PROSPECTUS
 
                         Centennial Cellular Corp. and
                     Centennial Cellular Operating Co. LLC,
 
                                  the Issuers,
                            Offer to Exchange Their
             10 3/4% Senior Subordinated Notes due 2008, Series B,
                      for Any and All of Their Outstanding
              10 3/4% Senior Subordinated Notes due 2008, Series A
 
                                ---------------
 
     Centennial Cellular Corp. and Centennial Cellular Operating Co. LLC, as
issuers, are offering to exchange $370 million of their 10 3/4% Senior
Subordinated Notes due 2008, Series B ("New Notes"), which will have been
registered under the Securities Act of 1933, for $370 million of their
outstanding 10 3/4% Senior Subordinated Notes due 2008, Series A (the "Old
Notes" and, collectively with the New Notes, the "Notes"). The Company and
Centennial Cellular Operating Co. LLC will not receive any proceeds from this
exchange offer and have agreed to pay all the expenses related to it.
Centennial Cellular Operating Co. LLC is a wholly-owned subsidiary of the
Company.
 
   .  The New Notes are identical in all material respects to the Old Notes,
      except for certain transfer restrictions, registration rights and
      additional interest provisions relating to the Old Notes.
 
   .  Interest accrues from the date of issuance at the rate of 10 3/4% per
      annum, payable semi-annually in arrears on each June 15 and December
      15, commencing June 15, 1999.
 
   .  The New Notes are unsecured (except to the extent of the first three
      interest payments, which are secured by a portfolio of governmental
      securities pledged for the benefit of holders of the Notes) and
      subordinated to all existing and future Senior Debt of the issuers.
 
   .  They rank equally with all future senior subordinated indebtedness and
      rank senior to all future subordinated indebtedness. The New Notes
      effectively rank junior to all liabilities of Centennial Cellular
      Operating Co. LLC's subsidiaries. As of November 30, 1998, after giving
      pro forma effect to the merger of CCW Acquisition into Centennial
      Cellular Corp. (which is described in this Prospectus) and certain
      transactions to finance this merger, Centennial Cellular Operating Co.
      LLC would have had $936.0 million of senior indebtedness and $370.0
      million of senior subordinated indebtedness outstanding. The
      subsidiaries of Centennial Cellular Operating Co. LLC would not have
      had any long term-term indebtedness outstanding (other than their
      guarantees of Centennial Cellular Operating Co. LLC's indebtedness
      under its credit facility). As of November 30, 1998, after giving pro
      forma effect as described, Centennial Cellular Corp. (without its
      subsidiaries) would have had no indebtedness outstanding other than its
      guarantee of the credit facility, $180 million (face amount) of
      subordinated notes issued to WCAS Capital Partners III, L.P. and its
      obligations as co-obligor on the Notes.
 
   .  The Exchange Offer is being made for all of the Old Notes and expires at
      5:00 p.m., New York City time, on [     ], 1999.
 
   .  The Exchange Offer is subject to customary terms and conditions.
 
     Consider carefully the "Risk Factors" beginning on page 27 of this
Prospectus.
 
     You should rely only on the information contained in this Prospectus or
that we have referred you to. We have not authorized anyone to provide you with
information that is different. We are not offering to sell or asking you to buy
anything other than the New Notes. We are not offering to sell or asking you to
buy anything in any jurisdiction where doing so would be against the law.
 
     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or passed upon the
adequacy or accuracy of this Prospectus. Any representation to the contrary is
a criminal offense.
 
                  The date of this Prospectus is      , 1999.

                      WHERE YOU CAN FIND MORE INFORMATION
 
      We have filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-4 (the "Registration
Statement") under the Securities Act with respect to the 10 3/4% Senior
Subordinated Notes due 2008 (the "New Notes"). As allowed by the Commission's
rules, this Prospectus does not contain all of the information included in the
Registration Statement. Our descriptions in this Prospectus concerning the
contents of any contract, agreement or document are not necessarily complete.
For those contracts, agreements or documents that we filed as exhibits to the
Registration Statement, you should read the exhibit for a more complete

      Centennial Cellular Corp. ("Centennial" or the "Company") is currently
and will continue to be required to file annual, quarterly and special reports,
proxy and information statements with the Commission. You may read and copy any
document we file with the Commission, including the Registration Statement, at
the Commission's public reference room at Judiciary Plaza, 450 Fifth Street,

payment of a duplicating fee, by writing to the Commission at 450 Fifth Street,

      Centennial Cellular Operating Co. LLC ("Centennial Cellular Operating")
is a wholly-owned subsidiary of Centennial. Because of this relationship and
because the New Notes are co-issued by Centennial
 
                                       2

and Centennial Cellular Operating, we expect to receive advice from the staff

Act").

                           FORWARD-LOOKING STATEMENTS
 
      This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties and assumptions about us, including, among other things:
 
   .  Our high degree of leverage and the requirement for significant and
      sustained growth in our cash flow to meet our debt service
      requirements,
 
   .  That we are a holding company and the notes are structurally
      subordinated to all indebtedness of our subsidiaries, including
      guarantees by our subsidiaries of all indebtedness under our $1.05
      billion credit facility (approximately $936 million of which was drawn
      at closing of the merger and a portion of which was borrowed directly
      by our Puerto Rico subsidiary),
 
   .  Our history of net losses and the expectation of future losses,
 
   .  That the telecommunications industry is highly competitive,
 
   .  That new technologies or new business opportunities will require
      additional investments in network capacity or additional capital
      spending,
 
   .  That the success of any acquisitions will depend on our ability to
      integrate acquired businesses,
 
   .  That the telecommunications industry is subject to rapid and
      significant changes in technology,
 
   .  That there is potential for adverse regulatory change and the need for
      regulatory approvals in the operation of our business and renewal of
      our cellular licenses,
 
   .  Fluctuations in market value of our licenses,
 
   .  Risks associated with the regional economic conditions in the areas we
      operate our business,
 
   .  Operating costs due to fraud,
 
   .  That a decline in roaming rates may materially adversely affect us,
 
   .  That a dispute regarding reverse billing may materially adversely
      affect us,
 
   .  That the indenture governing the notes will require us to offer to
      purchase all of the notes issued and outstanding upon any change of
      control and that the credit facility contains similar provisions,
      which purchases, in each case, we may not have sufficient funds to
      consummate,
 
                                       3
<PAGE>
 
   .  That the indenture and the credit facility impose significant
      operating and financial restrictions on Centennial Cellular Operating,
 
   .  That Centennial Cellular Operating has pledged the capital stock of
      all its direct and indirect subsidiaries to the lenders under the
      credit facility and that all of the assets of such subsidiaries are
      pledged to such lenders,
 
   .  That Centennial has unconditionally guaranteed the obligations of the
      borrowers under the credit facility,
 
   .  That Centennial, as co-obligor, has no assets other than the stock of
      Centennial Cellular Operating and Centennial is not subject to the
      covenants contained in the indenture governing the notes,
 
   .  That the right of the trustee under the indenture and a Pledge and
      Escrow Agreement to obtain payment on the notes upon the occurrence of
      an event of default may be significantly impaired by applicable
      bankruptcy law,
 
   .  The lack of certainty with respect to how a court might decide a suit
      by an unpaid creditor on the basis of fraudulent conveyance,
 
   .  The potential effect of Year 2000 computer issues,
 
   .  Risks associated with new management and any future changes in
      management,
 
   .  That certain equity investors control Centennial and its subsidiaries
      and have the power to elect directors and take other corporate
      actions,
 
   .  That we have limited ability to direct the operations of the systems
      in which we hold minority cellular investment interests as a limited
      partner and that our interests in such systems may be diluted if we do
      not meet a capital call,
 
   .  The potential effect of equipment failure or natural disaster on our
      business,
 
   .  Concerns about radio frequency emissions from cellular handsets, and
 
   .  The absence of a public market for the New Notes.
 
      We undertake no obligation to publicly update or revise any forward-
looking statements, whether as a result of new information, future events or
otherwise. In light of these risks, uncertainties and assumptions, the forward-
looking events discussed in this Prospectus might not occur.
 
                                 CERTAIN TERMS
 
      Interests in cellular markets that are licensed by the FCC are commonly
measured on the basis of the population of the market served, with each person
in the market area referred to as a "Pop." The number of Pops or Net Pops owned
is not necessarily indicative of the number of subscribers or potential
subscribers. As used in this Prospectus, unless otherwise indicated, the term
"Pops" means the estimate of the 1996 population of a Metropolitan Statistical
Area ("MSA") or Rural Service Area ("RSA"), as derived from the 1997 Paul Kagan
Associates population estimates. The term "Net Pops" means the estimated
population with respect to a given service area multiplied by the percentage
interest that the Company owns in the entity licensed in such service area.
MSAs and RSAs are also referred to as "markets." The term "wireline" license
refers to the license for any market initially awarded to a company or group
that was affiliated with a local landline telephone carrier in the market. The
term "non-wireline" license refers to the license for any market that was
initially awarded to a company, individual or group not affiliated with any
landline carrier. The term "PCS" means personal communications services.

      Our company is one of the largest independent wireless telecommunications
service providers in the United States and Puerto Rico with approximately 10.8
million Net Pops and 384,600 subscribers as of November 30, 1998. Centennial
Rural Cellular serves 5.8 million Net Pops and its service area covers
approximately 81,645 square miles. Our subsidiary, Centennial de Puerto Rico,
is a fully integrated provider of communications services in Puerto Rico. These
operations utilize a PCS license that covers 3.8 million Pops in Puerto Rico
and the U.S. Virgin Islands and a Competitive Local Exchange Carrier ("CLEC")
license to operate in Puerto Rico. In addition, we own minority shares,
representing approximately 1.2 million Net Pops, in certain other cellular
operations controlled and managed by other cellular operators ("Minority
Cellular Investment Interests").

      The success of our company's operating and financial performance has been
driven by the quality and experience of its management and employees. We expect
to continue to benefit from the experienced members of operating management who
are expected to remain at Centennial Rural Cellular following the Merger. This
management team built the Company through internal growth and acquisitions from
approximately 1.7 million Net Pops in 1988 to approximately 10.8 million Net
Pops (including those in Puerto Rico and Minority Cellular Investment
Interests) as of November 30, 1998. The addition of Michael Small, formerly the
Chief Financial Officer of 360(degrees) Communications Company (now a
subsidiary of ALLTEL Corporation), as our Chief Executive Officer following the
Merger complements the existing management team. Rudy J. Graf, who has been the
Chief Operating Officer of the Company since 1991, continues to manage the day-
to-day operations of the Company.
 
Centennial's Rural Cellular Systems
 
      Centennial's domestic consolidated systems are among the leading
independent providers of rural non-wireline cellular telecommunications
services. We believe our rural and small-city cellular systems provide strong
growth opportunities due to lower penetration rates and higher subscriber
growth rates. We focus on underdeveloped rural and small-city cellular areas
that have a significant number of potential customers for wireless
communications because we believe these areas offer:
 
     .  Potential Penetration Growth. We believe these areas are in the
        early stages of their growth cycles and offer significant
        opportunities for increases in penetration and cellular usage;
 
     .  Insulation from Potential Competition. These regions are currently
        subject to less competition from other wireless providers (such as
        PCS) as compared to larger MSAs, and the population density of
        these regions suggests that the build-out of a PCS network may not
        be economically attractive to competitors at present; and
 
     .  Above-Average Revenue per Subscriber. Our domestic markets, which
        are strategically located between larger metropolitan areas, tend
        to exhibit long commute times and well-traveled roadways that have
        the potential to generate high levels of cellular minutes of use
        ("MOUs") and roaming revenues.
 
      The Company's domestic cellular interests consist primarily of three
operating clusters:
 
     .  Michiana Cluster contains approximately 3.4 million Net Pops in
        Michigan, Ohio and Indiana, covering portions of three major
        interstate highways that connect Chicago, Detroit and Indianapolis.
 
     .  East Texas/Louisiana Cluster contains approximately 2.1 million Net
        Pops, covering portions of interstate highway I-10, as well as
        sections of Texas, Louisiana and Mississippi adjacent to Houston,
        New Orleans, Shreveport and Baton Rouge.
 
     .  Southwestern Cluster contains approximately 296,000 Net Pops,
        covering the Yuma, Arizona and El Centro, California markets and is
        bordered by Los Angeles to the northwest, San Diego to the west,
        Phoenix to the east and Mexicali, Mexico to the south.
 
      Our domestic operations have achieved significant increases in revenue,
EBITDA and number of subscribers since 1988. For the year ended May 31, 1998,
the Company's domestic operations earned revenue of $182.9 million,
representing a CAGR of 28% over the previous two fiscal years. EBITDA from
domestic operations for the year ended May 31, 1998 was $86.7 million,
representing a CAGR of 34% over the previous two fiscal years. As of May 31,
1998, the Company's domestic operations had approximately 252,700 subscribers,
representing a CAGR of 37% over the number of subscribers in the previous two
fiscal years.

Centennial's Puerto Rico Systems
 
      Our Puerto Rico business, which are conducted through Centennial de
Puerto Rico, is a facilities-based integrated communications provider ("ICP")
of a broad range of wireless and wireline services in the Commonwealth of
Puerto Rico (an area covering approximately 3.8 million Pops). It is (i) the
only provider of PCS services in the Puerto Rico market, (ii) a provider of
facilities-based wireless local loop services to both business and residential
customers, and (iii) a provider of local, long distance and enhanced data
services through its subsidiary, Lambda Communications Inc. ("Lambda CLEC"),
which competes with the incumbent Puerto Rico Telephone Company ("PRTC"). We
believe that Puerto Rico represents an attractive market for communications
services due to unmet demand for wireless and local phone service, high
population density in the island's metropolitan areas, a growing economy and a
stable business environment.
 
      Centennial de Puerto Rico offers wireless and wireline services using a
shared Lucent Technologies 5 ESS switch and its sophisticated fiber optic
network, which contains over 292 route miles of fiber throughout the island of
Puerto Rico. The digital PCS network allows for coverage in most areas of
Puerto Rico using its established base of 120 cell sites and code division
multiple access ("CDMA") technology to transmit its calls.
 
 .  Wireless Services. Centennial de Puerto Rico offers both PCS and wireless
   local loop service to its customers. Our PCS business currently covers
   approximately 85% of the total Pops on the island of Puerto Rico and targets
   high volume users. We began offering PCS in December 1996 and as of November
   30, 1998 had approximately 98,700 subscribers, an increase of 95% over our
   approximately 50,700 subscribers at November 30, 1997. Our average monthly
   revenue ("ARPU") per PCS customer was approximately $89 during the three
   months ended November 30, 1998, compared to approximately $46 for the
   average U.S. wireless customer for the six months ended June 30, 1998,
   according to data from the Cellular Telecommunications Industry Association
   ("CTIA"). Centennial de Puerto Rico began offering wireless local loop
   service to business and residential customers in August 1997. Our ARPU per
   wireless local loop customer was $87 during the three months ended November
   30, 1998. This service uses our fully digital CDMA network in Puerto Rico
   and had over 14,200 subscribers as of November 30, 1998.
 
 .  Wireline Services. Lambda CLEC provides local, long distance and enhanced
   data services (including Internet-related services) to business and
   government customers over our high bandwidth, fiber optic network. We
   believe that our targeted CLEC customers have sophisticated communications
   service requirements, including the need for a reliable network providing
   data access and private line services and high quality customer service.
   Lambda CLEC has grown rapidly since its inception in September 1997,
   primarily due to its ability to offer a broad range of products as well as
   responsive and reliable service in an underserved market. Lambda CLEC
   provided approximately 41.7 million MOUs to its customers in November 1998,
   an increase of 87% over the MOUs provided in May 1998.
 
      Since operations commenced in December 1996, Centennial de Puerto Rico
has achieved significant growth in subscribers, revenue and EBITDA, which we
attribute to our premium service capabilities, experienced local management
team and limited competition in the region. Revenue for the fiscal year ended
May 31, 1998 was $54.6 million, compared to $5.9 million for the year ended May
31, 1997. EBITDA for the fiscal year ended May 31, 1998 was $12.5 million,
compared to an EBITDA deficit of $(8.4) million for the prior period. Revenue
for the six months ended November 30, 1998 was $51.8 million. EBITDA for the
six months ended November 30, 1998 was $21.3 million or $42.6 million on an
annualized basis.

                     Overview of Centennial Rural Cellular
 
Competitive Strengths in Rural Cellular Markets
 
 .  Significant Potential for Higher Penetration Levels. Centennial Rural
   Cellular's predominantly rural and small-city markets have lower penetration
   levels than most major metropolitan areas. In its three rural cellular
   clusters, Centennial's domestic operations have achieved a penetration rate
   of 4.9% as of November 30, 1998. According to industry estimates, the
   typical big city U.S. cellular operator's penetration rate is approximately
   10.8%. We believe that our domestic clusters are in the early stages of
   their growth cycles and afford significant opportunities for improvements in
   financial performance as the penetration levels in these regions follow a
   growth pattern similar to that observed in the more mature metropolitan
   cellular markets. We also believe that our continuing investment in both
   coverage and distribution has enhanced our potential to achieve higher
   penetration levels.
 
 .  Limited Near-Term PCS Competition. We have benefited from the fragmented
   nature of current competition in our domestic markets and expect to continue
   to benefit from an anticipated lack of near-term PCS competition. We believe
   that we may earn substantial PCS roaming revenues and remain relatively
   insulated from direct PCS competition because we believe that building new
   PCS networks is not currently economically attractive in most of our
   domestic markets, given the relatively low population density in these
   areas. We expect larger urban PCS operators to continue to use roaming
   agreements rather than to incur the significant expenditures associated with
   entering our markets. We have been aggressive in pricing our roaming rates
   in part to discourage urban wireless providers from expanding their
   footprints into Centennial's service areas.
 
 .  Significant Roaming Revenue. We have benefited from substantial roaming
   traffic within our coverage areas. Our company has successfully built strong
   franchises in rural areas that adjoin more densely populated markets and
   benefits from significant roaming revenue generated from intercity traffic
   between these larger metropolitan areas. Roaming arrangements with
   neighboring urban cellular operators are lucrative for our company because
   they generate incremental minutes of use on our existing network, require no
   additional marketing costs and entail few, if any, uncollectible accounts.
   In addition, our aggressive pricing policies for roaming rates are designed
   to encourage certain neighboring cellular providers to include portions of
   our service areas within their home calling regions, thereby increasing
   total minutes of use on our systems. Our roaming revenue from our company's
   domestic systems has increased at a compounded annual growth rate of
   approximately 24% over the last four fiscal years to $58.9 million for the
   year ended May 31, 1998.
 
 .  Superior Coverage and Features with Digital-Ready Infrastructure. We believe
   that our networks offer superior coverage and features compared to
   competitors in our markets. Our company has made capital expenditures of
   approximately $78 million (excluding acquisition of licenses) during its
   last two completed fiscal years to deploy cell sites, including 151 sites
   added in fiscal 1998, to install Nortel time-division multiple access
   ("TDMA")-capable supernode switches and to develop a state-of-the-art,
   digital-ready infrastructure in its domestic markets. These improvements
   have yielded low dropped and blocked call rates for the three months ended
   May 31, 1998 of 0.077% and 1.6%, respectively, which we believe are lower
   than those of a typical cellular carrier and demonstrates the high quality
   of our domestic network. Additionally, our sophisticated network permits us
   to offer subscribers premium service features, such as call waiting, three-
   way calling and voice mail, for additional revenue.
 
 
                                       8

 .  High Average Revenue Per Unit. Centennial's domestic operations have
   consistently recorded higher ARPU than those of typical wireless carriers in
   the United States. Our company's domestic operations recorded ARPU of $68
   for the year ended May 31, 1998, as compared to the industry average of $46,
   according to data from the CTIA. We believe that we will continue to enjoy
   high ARPUs as a result of (i) our expanded regional calling areas, (ii) the
   increasing popularity of our revenue-enhancing, premium service features
   such as call-waiting and voice mail and (iii) the potential continued growth
   in roaming revenues from neighboring metropolitan cellular and PCS providers
   as wireless penetration continues to grow.
 
 .  Direct Distribution System and Customer Care. Our company controls its
   distribution channels, including 65 retail outlets and 700 sales
   representatives in the United States (excluding Puerto Rico). Our domestic
   direct sales channel is larger than that of our local competitors and gives
   us greater control over the expectations of our customers, resulting in
   lower churn and higher customer satisfaction. We seek to assure consistently
   high-quality customer service by establishing local installation and repair
   facilities in all of our domestic systems and by enabling customers to
   report service problems 24 hours a day. The success of this emphasis on
   customer service is evidenced by the Company's domestic average monthly
   churn rate of 1.8%, which we believe is lower than that of a typical
   cellular carrier and demonstrates customer satisfaction with our services.
 
Rural Cellular Business Strategy
 
      Our objective is to become the leading provider of cellular
communications services in our domestic market clusters, while maximizing
revenue and cash flow by offering superior service and extensive coverage in
our markets. The principal elements of this strategy are to:
 
     .  Continue to Develop Market Clusters. We cluster our cellular
        systems geographically, which enables us (i) to offer subscribers a
        larger regional calling area, (ii) to achieve certain operating,
        marketing and customer service efficiencies and (iii) to increase
        efficient utilization of our company's network infrastructure.
        Clustering allows us to offer our subscribers more areas of
        uninterrupted service as they travel through a region. The Company
        thereby captures more of its subscribers' total minutes of airtime,
        which increases revenue and decreases the costs associated with
        providing airtime on competitors' networks. Our domestic markets,
        which are strategically located between larger metropolitan areas,
        exhibit a concentration of small businesses, long commute times and
        well-traveled roadways that have the potential to generate high
        levels of cellular use.
 
     .  Continue Build-Out of Advanced, Digital-Ready Network. We intend to
        continue to expand and improve coverage, increase capacity and
        build out our systems within our current geographic markets. We
        have made significant capital expenditures to deploy additional
        cell sites and to develop a state-of-the-art, digital-ready
        infrastructure. We believe that the investment necessary to switch
        to a fully-digital system is approximately $2 million (excluding
        the cost of new handsets) and will be incurred over the next two to
        three years as competition dictates and as prices of digital
        handsets fall. We believe that expanding and improving coverage and
        capacity in our systems will attract additional subscribers,
        increase usage by existing subscribers, increase roaming activity
        and further enhance the efficiency of our networks. Additionally,
        we expect to benefit from the increasing popularity of premium
        service features that we offer to subscribers, such as call waiting
        and voice mail.
 
 
                                       9
<PAGE>
 
     .  Pursue Selective Acquisition Strategy. Our strategy is to expand
        our current domestic clusters through the selective acquisition of
        small to mid-sized MSAs and RSAs or potentially larger MSAs located
        in contiguous markets that we believe are undervalued or
        underdeveloped or that possess characteristics indicative of
        potentially high cellular usage and superior financial performance.
        Upon acquiring a system, our company aims to make certain
        operational and organizational changes in order to increase the
        number and quality of subscribers and enhance operating cash flow,
        while controlling subscriber acquisition costs and promoting
        superior customer service.

                     Overview of Centennial de Puerto Rico
 
Puerto Rico Market Opportunity
 
      Our company also has a significant presence in Puerto Rico. We believe
that several factors make Puerto Rico an attractive market for communications
services. These factors include:
 
     .  Growing Economy and Stable Business Environment. Puerto Rico became
        a territory of the United States in 1898 and has been a
        Commonwealth since 1952. Puerto Rico is a major center of Caribbean
        commerce and finance and serves as a gateway or regional
        headquarters for businesses operating in Latin America and the
        Caribbean, including McDonald's Corporation, Johnson & Johnson and
        Mitsubishi. The island has a stable currency and regulatory
        environment, as Puerto Rico is subject to the U.S. legal system,
        including regulation by the Federal Communications Commission
        ("FCC"). In 1997, Puerto Rico's gross national product was
        approximately $32 billion, which represented a real growth rate of
        approximately 3.1% over 1996. The island has a population of
        approximately 3.8 million people, of which approximately 71% live
        in urban areas. The largest metropolitan area in our service area,
        the San Juan/Caguas MSA with over two million Pops, is
        characterized by a high population density of 1,880 persons per
        square mile (the mainland U.S. MSA average is 325).
 
     .  Underserved Telecommunications Market. We believe that there is
        substantial unmet demand for both wireless and wireline
        telecommunications services in Puerto Rico. Current market
        penetration for wireless services (including cellular, PCS and
        Enhanced Specialized Mobile Radio ("ESMR")) is approximately 11%,
        compared to approximately 22% for existing wireless providers in
        the U.S., according to estimates from the CTIA. We believe that the
        Puerto Rico market should support penetration levels comparable to
        those in U.S. markets. In addition, the high population density in
        Puerto Rico's metropolitan areas is well suited to the signal
        propagation characteristics of PCS, which requires a greater number
        of cell sites than cellular service to provide coverage in a given
        area. Prior to the introduction of Lambda CLEC's services, wireline
        telephone services were available only from the PRTC. Puerto Rico
        currently has approximately 38 phone lines per 100 Pops, compared
        to approximately 54 phone lines per 100 Pops in the U.S. We believe
        that the rapid subscriber growth achieved by Lambda CLEC since
        introduction reflects significant market demand by business
        customers for a broad range of product and service offerings, high
        bandwidth connectivity, prompt installation and responsive customer
        service.
 
     .  Limited Near-Term PCS Competition. Our company was the first
        provider to offer PCS in Puerto Rico. TeleCorp, Inc. ("TeleCorp"),
        as part of a joint venture with AT&T Wireless Services, is
        currently in the early stages of construction of a PCS network in
        Puerto Rico. The Company does not believe that TeleCorp will
        achieve significant network coverage within the next 12 months.
        While other competitors may be expected to enter the market in the
        future, we believe that this will offer additional revenue
        opportunities to the extent that such competitors contract with us
        for "backhaul" services to connect their cell sites to their
        switch, rather than constructing their own networks or contracting
        with the PRTC.

Puerto Rico Business Strategy
 
      Our business strategy in Puerto Rico is to become an integrated, full
service provider of superior wireless and wireline communications services
throughout Puerto Rico. The principal elements of this strategy are to:
 
     .  Become a Single Source Provider of Communications Services. We
        believe that there is a significant demand in Puerto Rico for an
        integrated bundle of wireless and wireline communications services
        tailored to satisfy the customer's total communications needs. Our
        company currently offers PCS service as well as local, domestic and
        international long distance, data and broadband services. We
        believe that our ability to provide an integrated package of
        communications services will enable us to (i) rapidly penetrate
        targeted markets, (ii) increase our share of existing customers'
        expenditures for communications services, (iii) increase customer
        satisfaction and (iv) reduce customer turnover.
 
     .  Target High Usage Customers. We will continue to focus on building
        a solid base of high usage customers in Puerto Rico. We believe
        that our 100% digital CDMA network, which offers subscribers
        superior voice quality, reliability, anti-fraud protection and
        premium features such as caller ID, call waiting, voice mail and
        conference calling, provides us with competitive advantages to
        attract and retain these customers. Our company's average PCS
        customer used approximately 360 MOUs per month and generated
        approximately $89 in monthly revenue during the three months ended
        November 30, 1998. The average cellular customer in the U.S. market
        uses approximately 130 MOUs per month and the average wireless
        customer generates approximately $46 in monthly revenue. The
        Company's average wireless local loop customer used approximately
        760 MOUs per month and generated approximately $87 in monthly
        revenue during the three months ended November 30, 1998. Lambda
        CLEC's service is targeted at large businesses with sophisticated
        communications needs and high usage patterns and has already
        attracted a number of significant local businesses, including MCI,
        Banco Santander and El Nuevo Dia, Puerto Rico's largest newspaper.
        In addition, we believe that all of the Internet service providers
        operating in Puerto Rico currently use Lambda CLEC's services.
        Lambda CLEC's average customer generated monthly revenues of
        approximately $16,000 during the month ended November 30, 1998.
 
     .  Leverage Technologically Advanced, Integrated Network. Our PCS
        infrastructure and fiber optic network provide us with a platform
        to offer an integrated package of wireless and wireline services.
        The system is served by a Lucent Technologies 5 ESS switch for both
        wireless and wireline services and the fiber optic network supports
        a self-healing SONET architecture. The construction of our planned
        network of fiber optics, cell sites and microwave transmitters has
        been largely completed. The installation of additional cell sites
        to provide service and network capacity throughout Puerto Rico is
        expected to be completed within the next twelve months, increasing
        estimated network coverage from 85% as of August 31, 1998 to 90% as
        of May 31, 1999. Thereafter, we expect to make other improvements
        to increase network capacity and enhance coverage in response to
        usage patterns. We intend to broaden our service offerings in the
        coming months to include dial-around long distance, direct Internet
        access and wireless data transmission. We believe that expanding
        and improving coverage and capacity in our systems and our range of
        services will attract additional subscribers, increase usage by
        existing subscribers and further enhance the efficiency of our
        networks.

     .  Build High-End Brand with Reputation for Superior Customer
        Service. We intend to continue to build on our reputation as a
        provider of high quality communications services and superior
        customer service throughout Puerto Rico. Our company designs and
        implements specific marketing strategies for its wireless system
        using a variety of television, billboard, radio and newspaper
        advertising to stimulate net subscriber growth and to focus on
        customers who are likely to generate higher monthly revenues,
        primarily business users. We seek to capitalize on our brand name
        recognition to attract new wireless and CLEC customers and to
        further develop our reputation as a provider of reliable and
        sophisticated communications services. Furthermore, by retaining
        control of our distribution channels, including our 52 retail
        outlets and 315 sales representatives in Puerto Rico, we maintain
        greater control over the expectations of our customers, resulting
        in consistently high levels of customer service and customer
        satisfaction.
 
     .  Maintain Positive EBITDA Growth. We intend to grow our subscriber
        base in Puerto Rico while maintaining its focus on attracting high
        volume users that generate higher revenues and EBITDA. Centennial
        de Puerto Rico achieved positive EBITDA within nine months of
        commencing its wireless and Lambda CLEC services and in fiscal 1999
        had annualized EBITDA of $42.6 million, based upon EBITDA for the
        six months ended November 30, 1998. Our sophisticated fiber optic
        network, which serves as the backbone to both our wireless and
        Lambda CLEC services, gives us greater flexibility to compete
        effectively in the marketplace, as we are not merely reselling
        services and infrastructure provided by other companies. In
        addition, unlike typical CLECs, we generally extend our network
        into new locations only upon request of our customers who then pay
        their own building-entry costs.
 
Recent Developments
 
      In September 1998, the Commonwealth of Puerto Rico sustained damage as a
result of the effects of Hurricane Georges. The Company has evaluated the
extent of damage to its Puerto Rico network infrastructure and the impact the
hurricane has had on the Company's Puerto Rico service revenue during the three
months ended November 30, 1998. After consideration of expected insurance
recoveries, the Company believes it will not incur significant losses as a
result of the effects of the damage caused by Hurricane Georges. During the
three months ended November 30, 1998, the Company recorded approximately $1.6
million of insurance recoveries related to subscriber refunds within revenue.

                            such New Notes. Each broker-dealer that receives
                            New Notes for its own account pursuant to the
                            Exchange Offer must acknowledge that it will
                            deliver a prospectus in connection with any resale
                            of such New Notes. See "Plan of Distribution." To
                            comply with the securities laws of certain
                            jurisdictions, it may be necessary to qualify for
                            sale or register the New Notes prior to offering or
                            selling such New Notes. The Company and Centennial
                            Cellular Operating do not currently intend to
                            register or qualify the sale of the New Notes in
                            any such jurisdictions.
 
Untendered Old Notes......  If you are eligible to participate in the Exchange
                            Offer but do not tender your Old Notes, you will
                            not have any further exchange rights and your Old
                            Notes will continue to be subject to certain
                            restrictions on transfer. Accordingly, the
                            liquidity of the market for your Old Notes could be
                            adversely affected. In general, such Old Notes may
                            not be offered or sold unless registered under the
                            Securities Act, except pursuant to an exemption
                            from, or in a transaction not subject to, the
                            Securities Act and applicable state securities
                            laws. See "The Exchange Offer--Consequences of
                            Failure to Exchange."

                             Terms of the New Notes
 
      The form and terms of the New Notes are identical in all material
respects to the Old Notes, except for certain transfer restrictions and
registration rights relating to the Old Notes. The New Notes will evidence the
same debt as the Old Notes, and both series of Notes will be entitled to the
benefits of the Indenture and treated as a single class of debt securities
thereunder. See "Description of the New Notes."
 
Securities Offered........  $370,000,000 aggregate principal amount of 10 3/4%
                            Senior Subordinated Notes due 2008, Series B.
 
                            December 15, 2008.
 
Maturity Date.............
                            June 15 and December 15 of each year, commencing
                            June 15, 1999.
 
Interest Payment Dates....
Ranking...................  The notes will be unsecured (except as described
                            under "--Security"), senior subordinated
                            obligations and will be subordinated to all of the
                            Obligors' existing and future senior indebtedness,
                            including all indebtedness of the Obligors under
                            the Credit Facility. The notes will rank equally
                            with all of the Obligors' other existing and future
                            senior subordinated indebtedness, and will rank
                            senior to all of the Obligors' subordinated
                            indebtedness. The notes effectively will rank
                            junior to all liabilities of the subsidiaries of
                            Centennial Cellular Operating, including
                            indebtedness under the Credit Facility. Because the
                            notes are subordinated, in the event of bankruptcy,
                            liquidation or dissolution, holders of the notes
                            will not receive any payment until holders of
                            senior indebtedness have been paid in full. The
                            terms "senior indebtedness" and "subordinated
                            indebtedness" are defined in the "Description of
                            the New Notes--Subordination" and "Description of
                            the New Notes--Certain Definitions" sections of
                            this Prospectus.
 
                            As of November 30, 1998, after giving pro forma
                            effect to the Merger, the Offering of Old Notes and
                            our use of the net proceeds from the Offering and
                            other financings related to the Merger, Centennial
                            Cellular Operating would have had outstanding
                            $936.0 million of senior indebtedness and $370.0
                            million of senior subordinated indebtedness. In
                            addition, on such a pro forma basis, the
                            subsidiaries of Centennial Cellular Operating would
                            have had no indebtedness outstanding other than
                            their guarantees of $936.0 million of Centennial
                            Cellular Operating's indebtedness under the Credit
                            Facility (a portion of which was borrowed directly
                            by Centennial de Puerto Rico); provided that
                            Centennial de Puerto Rico and its subsidiaries have
                            not initially guaranteed the obligations of
                            Centennial Cellular Operating under the Credit
                            Facility. As of November 30, 1998, after giving pro
                            forma effect as described, Centennial (without its
                            subsidiaries) would have had no indebtedness
                            outstanding other than $180 million (face amount)
                            of subordinated notes issued to WCAS Capital
                            Partners III, L.P., its guarantee under the Credit
                            Facility and its co-obligation under the notes.
 
Change of Control.........  Upon certain change of control events, each holder
                            of notes may require us to repurchase all or a
                            portion of its notes at a purchase price equal to
                            101% of the principal amount thereof, plus accrued
                            interest. See "Description of the New Notes--
                            Certain Covenants--

Optional Redemption.......  We may redeem the notes, in whole or in part, at
                            any time on or after December 15, 2003, at the
                            redemption prices (expressed as percentages of

                            Before December 15, 2001, we may redeem up to 35%
                            of the aggregate principal amount of the notes with
                            the net proceeds of a public equity offering or
                            strategic equity offering at 110.750% of the
                            principal amount thereof, plus accrued interest, if
                            at least 65% of the aggregate principal amount of
                            the notes originally issued remains outstanding
                            immediately after such redemption.
 
Change of Control
Optional Redemption.......
                            Upon certain change of control events, we may elect
                            to redeem all, but not some, of the notes at par,
                            together with accrued interest, plus an applicable
                            premium based on a discount rate calculated using
                            the interest rate of a Treasury security maturing
                            on the first redemption date plus 50 basis points;
                            provided, however, that the redemption price shall
                            be no less than 105.375%.
 
Security..................  The Company and Centennial Cellular Operating used
                            a portion of the proceeds from the offering of the
                            Old Notes to purchase a portfolio of government
                            securities in an amount sufficient to pay the first
                            three payments of interest on the notes. The
                            Company and Centennial Cellular Operating pledged
                            this portfolio of securities for the benefit of the
                            holders of the notes and may under certain
                            circumstances substitute other readily marketable
                            securities. See "Description of the New Notes--
                            Security."
 
Certain Covenants.........  The indenture governing the notes contains
                            covenants that, among other things, limit our
                            ability and the ability of our restricted
                            subsidiaries to:
 
                            .  incur additional indebtedness,
 
                            .  incur additional senior subordinated

                            .  pay dividends on, redeem or repurchase our
                               capital stock,
 
                            .  make investments,

                            .  guarantee indebtedness,

                            .  create certain liens,
 
                            .  consolidate, merge or transfer all or
                               substantially all of our assets and the assets
                               of our subsidiaries on a consolidated basis and
 
                            .  enter new lines of business.
 
                            These covenants are subject to important exceptions
                            and qualifications, which are described under the

                    Summary Historical Financial Information
 
      The following table sets forth summary historical consolidated financial
information for Centennial as of November 30, 1998 and for the six months ended
November 30, 1998 and 1997. Such data were derived from our unaudited condensed
consolidated financial statements and notes, but, in the opinion of our
management, include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the financial position and
results of operations for such periods. Operating results for the six months
ended November 30, 1998 and 1997 do not necessarily show what the results for a
full year may be. The table also sets forth summary historical consolidated
financial information for Centennial for the five years ended May 31, 1998.
Such data were derived from our audited consolidated financial statements and
notes. Since the information in this table is only a summary, you should read
our historical financial statements and the related notes, "--Sources and Uses
of Funds," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Unaudited Pro Forma Financial Information" found
elsewhere in this Prospectus.

     interest in earnings of limited partnerships controlled and managed by
     other cellular operators accounted for on the equity method.

 (2) Represents the percentage share of earnings of our consolidated
     subsidiaries that is allocable to unaffiliated holders of minority
     interests.
 
 (3) EBITDA is defined, for any period, as earnings before income from Minority
     Cellular Investment Interests, allocations to minority interests in
     consolidated subsidiaries, interest expense, interest income, income
     taxes, depreciation and amortization and gain on sale of assets. EBITDA is
     presented because it is a widely accepted financial indicator of a
     company's ability to service and/or incur indebtedness. EBITDA should not
     be considered an alternative to net income as a measure of our operating
     results or to cash flow as a measure of liquidity. In addition, although
     the EBITDA measure of performance is not recognized under generally
     accepted accounting principles, it is widely used by various companies as
     a general measure of a company's performance because it assists in
     comparing performance on a relatively consistent basis across companies
     without regard to depreciation and amortization, which can vary
     significantly depending on accounting methods (particularly where
     acquisitions are involved) or non-operating factors such as historical
     cost bases. Because EBITDA is not calculated identically by all companies,
     the presentation herein may not be strictly comparable to other similarly
     titled measures of other companies.
 
 (4) For the purposes of determining the ratio of earnings to fixed charges,
     earnings are defined as earnings before income taxes, minority interest
     and extraordinary items, plus fixed charges. Fixed charges include
     interest expense on all indebtedness, amortization of deferred debt
     issuance costs and one-third of rental expense on operating leases
     representing that portion of rental expense deemed to be attributable to
     interest. The ratio of earnings to fixed charges is less than one-to-one
     for all periods presented and, therefore, earnings are inadequate to cover
     fixed charges. The amount by which earnings exceeded (are less than) fixed
     charges for the six months ended November 30, 1998 and 1997 are $12,188
     and $(21,839), respectively, and for the years ended May 31, 1998, 1997,
     1996, 1995 and 1994 are $(45,382), $(43,189), $(33,412), $(47,117) and

                                  RISK FACTORS
 
      In addition to the other information in this Prospectus, you should
consider carefully the following risk factors before tendering your Old Notes
in the Exchange Offer.
 
Significant Indebtedness and Interest Payment Obligations
 
      The Company is highly leveraged as a result of the offering of Old Notes,
borrowings under the Credit Facility and the issuance of subordinated notes of
Centennial in the Mezzanine Financing. The proceeds of the Offering were used
as a portion of the financing of the Merger to (i) pay for shares of capital
stock of Centennial in the Merger, (ii) repay or repurchase certain
indebtedness of Centennial (including the outstanding notes acquired in the
debt tender offers), (iii) pay the fees and expenses incurred in connection
with the Merger, the financing of the Merger and any other transactions
contemplated by the Merger Agreement and (iv) purchase the pledged securities
that will fund the first three scheduled interest payments on the notes. See
"Use of Proceeds."
 
      As of November 30, 1998, after giving pro forma effect to the Offering
and other financing of the Merger, Centennial Cellular Operating's consolidated
long-term indebtedness would have been approximately $1.31 billion. In
addition, Centennial (without its subsidiaries) would have had $180 million
(face amount) of long-term indebtedness (other than its guarantee under the
Credit Facility and its co-obligation under the notes). Following the
financings related to the Merger, our consolidated long-term indebtedness was
substantially greater than our long-term indebtedness before the Merger. In
addition, the indenture governing the notes and our other debt instruments
allows us to incur additional indebtedness, including secured indebtedness. As
of November 30, 1998, on a pro forma basis, Centennial Cellular Operating would
have had an aggregate of $114.0 million available for borrowing under the
Credit Facility. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources." Our
ability to make payments with respect to the notes and to satisfy our other
debt obligations depends on our future operating performance, which will be
affected by prevailing economic conditions and financial, business and other
factors, certain of which are beyond our control.
 
      Our high level of indebtedness could have important consequences to
noteholders, such as:
 
     .  limiting our ability to obtain additional financing for future
        acquisitions (if any), working capital, capital expenditures or
        other purposes;
 
     .  limiting our ability to use operating cash flow in other areas of
        our business because we must dedicate a substantial portion of these
        funds to make principal payments and fund debt service;
 
     .  increasing our vulnerability to adverse economic and industry
        conditions;
 
     .  increasing our vulnerability to interest rate increases because
        borrowings under our Credit Facility are at variable interest rates;
        and
 
     .  increasing our vulnerability to competitive pressures, as many of
        our competitors will be less leveraged than we are.
 
      Upon the issuance of the notes, our consolidated interest expense has
increased compared to prior years. We currently believe that our cash flow,
together with available borrowings under the Credit Facility, will permit us to
pay our operating expenses and service our debts for the foreseeable future.
Our belief is based on significant assumptions, including, among other things,
that we will succeed in implementing our business strategy and that there will
be no material adverse developments in our business, liquidity or capital
requirements. If, in the future, we cannot generate sufficient cash from
operations to make scheduled payments on the notes or to meet our other
obligations, we will need to refinance, obtain additional financing or sell
assets. We cannot assure you that our business will generate cash flow, or that
we will be able to obtain
 
                                       27
<PAGE>
 
funding sufficient to satisfy our debt service requirements. On a pro forma
basis, earnings were insufficient to cover fixed charges for Centennial and
Centennial Cellular Operating by $161.8 million and $138.9 million for the year
ended May 31, 1998, and by $44.7 million and $32.9 million for the six months
ended November 30, 1998.
 
Covenant Restrictions
 
      We and our subsidiaries are subject to significant operating and
financial restrictions contained in the instruments governing the notes and our
Credit Facility. Such restrictions affect, and in many respects significantly
limit or prohibit, among other things, our ability to:
 
     .  borrow more funds,
 
     .  pay dividends,
 
     .  repay indebtedness prior to stated maturities,
 
     .  sell assets,
 
     .  make investments,
 
     .  engage in transactions with stockholders and affiliates,
 
     .  create liens, or
 
     .  engage in mergers or acquisitions.
 
      In addition, the Credit Facility requires us to maintain certain
financial ratios. These restrictions could also limit our ability to obtain
financing in the future, make needed capital expenditures, withstand a future
downturn in our business or the economy in general or in our specific areas of
coverage, or otherwise conduct necessary corporate activities. If we or our
subsidiaries fail to comply with these restrictions, we may be in default under
the terms of such indebtedness, even if we are otherwise able to meet our debt
service obligations. In the event of a default, the holders of such
indebtedness could elect to declare all such indebtedness, together with
accrued interest, to be due and payable and a significant portion of our other
indebtedness (including the notes) and that of our subsidiaries may become
immediately due and payable. We cannot assure you that we or our subsidiaries
would be able to make such payments or borrow sufficient funds from alternative
sources to make any such payment. Even if we were to obtain additional
financing, such financing may be on terms unfavorable to us.
 
Subordination of the Notes to Senior Debt; Structural Subordination of the
Notes to Subsidiary Debt
 
      The notes are subordinated to all our senior indebtedness. In addition,
the notes effectively rank junior to all liabilities of our subsidiaries. As of
November 30, 1998, after giving pro forma effect to the offering of Old Notes
and the Company's use of the net proceeds thereof, our borrowings under the
Credit Facility and an issuance of subordinated notes of Centennial, Centennial
Cellular Operating would have had outstanding $936.0 million of senior
indebtedness and $370 million of senior subordinated indebtedness. As of
November 30, 1998, after giving pro forma effect as described, (a) Centennial
(without its subsidiaries) would have had no indebtedness outstanding other
than $180 million (face amount) of subordinated notes issued to WCAS Capital
Partners III, L.P., its guarantee of $936.0 million of Centennial Cellular
Operating's indebtedness under the Credit Facility and its co-obligation on the
notes and (b) our subsidiaries would have had no indebtedness outstanding other
than their guarantees of $936.0 million of funded indebtedness under the Credit
Facility (a portion of which was borrowed directly by Centennial de Puerto
Rico, which indebtedness is effectively senior to the notes). We also may incur
additional senior indebtedness and our subsidiaries may incur additional
indebtedness consistent with the terms of our debt agreements. For example,
upon consummation of the offering of the Old Notes and the Company's use of the
net proceeds thereof, as of November 30, 1998, we would have had $114.0 million
available under our Credit Facility which, if borrowed, would be senior
 
                                       28
<PAGE>
 
indebtedness and would be guaranteed by our subsidiaries other than Centennial
de Puerto Rico and its subsidiaries. In the event of our bankruptcy,
liquidation or dissolution, our assets would be available to pay obligations on
the notes only after all payments had been made on our senior indebtedness. We
cannot assure you that sufficient assets will remain to make any payments on
the notes. In addition, certain events of default under our senior indebtedness
would prohibit us from making any payments on the notes. The term "senior
indebtedness" is defined in the "Description of the New Notes--Subordination"
section of this Prospectus.
 
      Our company depends on the cash flow from our subsidiaries to meet our
obligations, including all payments on the notes. Accordingly, our ability to
make payments to holders of the notes depends on the receipt of sufficient
funds from our subsidiaries. Because of the terms of existing and future
indebtedness of our subsidiaries, including the Credit Facility, which is
initially secured by the assets of our domestic subsidiaries, we may be
restricted in receiving funds from our subsidiaries. The indenture for the
notes permits our subsidiaries to enter into agreements which restrict
dividends and distributions to the obligors. See "Description of the New
Notes--Certain Covenants--Limitation on Restrictions on Subsidiary Dividends."
 
Notes Are Unsecured
 
      In addition to being subordinate to all of our senior indebtedness, the
notes are not secured by any of our assets (other than the funds pledged to pay
the first three interest payments). Our obligations under our Credit Facility
are secured by substantially all of our assets, including assets held by our
subsidiaries. Under the indenture governing the notes, the Obligors and their
subsidiaries are permitted to incur additional secured indebtedness. If we
became insolvent or are liquidated, or if payment under our Credit Facility is
accelerated, the lenders under our Credit Facility would be entitled to
exercise the remedies available to a secured lender under applicable law.
Therefore, our bank lenders will have a claim on such assets before the holders
of these notes. Because the notes are unsecured, there may be no assets
remaining for the holders of notes or any assets may be insufficient to pay off
the notes. See "Description of Certain Indebtedness."
 
Net Losses; Expectation of Future Net Losses
 
      Since our formation, we have concentrated on the acquisition, exchange,
construction, initial operation and development of cellular telephone systems
in our domestic markets and the provision of facilities-based integrated
communications in Puerto Rico. Our business operations have incurred net losses
for each of the past five fiscal years and, after giving pro forma effect to
the offering of the Old Notes and borrowings under the credit facility,
Centennial Cellular Operating would have incurred a net loss of $120.5 million
for the fiscal year ended May 31, 1998. Following the Merger, we expect to
report net losses for the foreseeable future due to increased interest payments
and non-cash charges such as depreciation and amortization. We cannot assure
you that in future periods our operations will generate sufficient earnings to
pay our obligations, including the notes.
 
Competition in Rural Cellular Markets
 
      Our principal business, wireless telephone service, is highly
competitive. Competition for wireless telephone service in each of our markets
is based primarily on the quality of service, price, system coverage,
enhancements offered, capacity and customer service. We compete with one
cellular licensee in each geographic area and most of these competitors are
larger, have greater financial resources than we do and may be less leveraged
than we are. We also face competition from paging companies, landline telephone
companies and resellers. The FCC requires cellular and PCS licensees to offer
service to resellers on a nondiscriminatory basis. A reseller buys blocks of
telephone numbers from cellular and PCS providers, usually at a discounted
rate, and resells the service to the public for a profit. Many
telecommunications companies resell wireless telephone service as a complement
to other services, such as long distance or local telephone services.
 
      As a result of recent regulatory and legislative initiatives, we also
face increased competition from entities using or proposing to use other
comparable communications technologies. The FCC currently is
 
                                       29
<PAGE>
 
licensing commercial PCS. The FCC identified two categories of PCS: broadband
and narrowband. PCS is not a specific technology, but a variety of potential
technologies that could compete with cellular telephone systems. For example,
the broadband PCS systems licensed to operate in the 2 GHz band may provide
wireless two-way telecommunications services for voice, data, graphic and other
transmissions. Equipment used for broadband PCS includes small, lightweight and
wireless telephone handsets, computers that can communicate over the airwaves
wherever they are located, and portable facsimile machines and other graphic
devices. Many PCS systems have commenced operations in the last few years. When
a PCS system employs microcell technology, as is common, it uses a network of
small, low-powered transceivers placed throughout a neighborhood, business
complex, community or metropolitan area to provide customers with mobile and
portable voice and data communications. Many PCS licensees who will compete
with us have access to substantial capital resources. In addition, many of
these companies, or their affiliates, already operate large cellular telephone
systems and thus bring significant wireless experience to this new marketplace.
To date, we have experienced little impact from PCS competition in our domestic
markets. However, there can be no assurance of the long-term effect these new
PCS licensees may have on us.
 
      ESMR is a two-way wireless communications service that incorporates
characteristics of cellular technology, including multiple low-power
transmitters and interconnection with the landline telephone network. ESMR
service may compete with cellular service by providing digital communication
technology, lower rates, enhanced privacy and additional features such as
electronic mail and built-in paging. Nextel Communications, Inc. is the primary
provider of such services today.
 
      We may also face competition from satellite-based services. The FCC has
issued a number of licenses to provide such services which would enable
subscribers to access mobile communications systems throughout the world.
Additional proposals for the provision of satellite services remain pending
with the FCC and foreign regulatory bodies must approve certain aspects of some
satellite systems. Although we may experience increased competition from such
services in the future, such systems have not affected our operations to date.
 
      The FCC has made available other frequency bands that may be used for the
provision of cellular-like services. The General Wireless Communications
Service ("GWCS") and the Wireless Communications Service ("WCS") are two such
services that are in their infancy. Although the FCC has proposed technical
rules for WCS that will make commercial mobile services like cellular and PCS
infeasible, there can be no assurance that the FCC will not adopt more flexible
WCS technical rules that will enable WCS licensees to provide service
comparable to cellular and PCS services.
 
      We are unable to predict whether such competing technologies or any new
technologies will be successful and, if successful, whether any will provide
significant competition for us. We cannot assure you that one or more of the
technologies that we currently use in our business will not become inferior or
obsolete at some time in the future.
 
Competition in Puerto Rico Market
 
Competition from Cellular Systems
 
      The market for wireless services is highly competitive in Puerto Rico.
Our two main competitors for wireless services in the Puerto Rico market are
CoreComm Incorporated ("CoreComm"), a publicly traded U.S. company, and the
Puerto Rico Telephone Company, which is currently owned by the Commonwealth of
Puerto Rico but which has agreed to sell a significant stake to GTE
Corporation, a U.S. telecommunications company which will control the PRTC's
board of directors. The parties' public statements indicate that they expect
the transaction to close during the first quarter of 1999. In July 1998, GTE
agreed to merge with Bell Atlantic. Both CoreComm and PRTC were earlier
entrants into the Puerto Rico wireless market, have greater resources than we
do and currently hold subscriber market shares of approximately 47% and 40%,
respectively. CoreComm and PRTC offer both analog and digital cellular service
(using TDMA technology) to their
 
                                       30
<PAGE>
 
subscribers and offer greater roaming capacity to their customers traveling
outside Puerto Rico, as both have roaming agreements with major cellular
providers in the U.S. We currently offer roaming ability in the U.S. pursuant
to an agreement with Sprint.
 
Competition From Other Broadband PCS Systems
 
      The FCC has issued a 30 MHz broadband PCS license for the Puerto Rico-
U.S. Virgin Islands MTA to TeleCorp. The FCC has also issued four broadband PCS
licenses for the San Juan, Puerto Rico Basic Trading Area ("BTA"), the
Mayaguez-Aguadilla-Ponce, Puerto Rico BTA and the U.S. Virgin Islands BTA to
other entities, including a 10 MHz license to the PRTC. If these licenses
become operational, these broadband PCS systems will present additional
competition to our PCS operations in Puerto Rico. We do not believe that
TeleCorp, which is in the early stages of construction of its PCS system as
part of a franchise relationship with AT&T Wireless Services, will achieve
significant network coverage within the next twelve months.
 
      New PCS competitors will face a number of significant hurdles in building
out their systems in Puerto Rico, including the development of a "backhaul"
network connecting its cell sites with its switch. A competitor may (i) utilize
PRTC's network, (ii) construct its own network, (iii) utilize our fiber optic
network or (iv) choose a combination of these methods. We believe that few
competitors will choose to build their own networks because of the significant
cost and time constraints, nor will they choose to contract with the PRTC
because of its poor reliability and the long wait times required for new T-1
service to be added. Thus, we believe that some of our competitors in Puerto
Rico may seek to contract with us for backhaul services.
 
Competition From Resellers
 
      The FCC requires all cellular and PCS system operators to provide service
on a nondiscriminatory basis to resellers, who provide service to customers but
do not hold an FCC license or own facilities for the provision of such
services. Instead, a reseller buys blocks of cellular telephone numbers from a
licensed carrier, usually at a discounted rate, and resells service to the
public through its own distribution methods. Thus, a reseller may be both a
customer of a cellular or PCS provider and also a competitor. Ameritel, acting
as a reseller, is currently offering cellular services at Radio Shack stores
throughout Puerto Rico. We do not know of any other significant cellular
resellers currently operating in competition with our PCS system.
 
Wireline Competition
 
      Our primary competitor for wireline service is the incumbent provider,
the Puerto Rico Telephone Company, which has considerably greater resources
than we do. GTE, which recently entered into a merger agreement with Bell
Atlantic, has agreed to buy a significant stake in the PRTC and will control
PRTC's board of directors. GTE and Bell Atlantic also have significantly
greater resources than we do and may make changes to improve service which in
turn may strengthen the PRTC's competitive position. The growth of the
Company's market presence will depend upon its ability to obtain customers that
are underserved by the PRTC (or its successor) or looking for an alternative.
Because of the Company's ability to provide more timely installation and
service to date, the Company has primarily attracted customers on the basis of
quality and service rather than price. KMS, a U.S. corporation based in New
Jersey, has announced plans to set up a fiber optic network in Puerto Rico to
offer Internet access and data transmission, although it has not yet commenced
construction.
 
Risks Associated With Acquisitions
 
      Since August 1988, we have acquired 29 cellular systems in the United
States that we own and manage. Following the Merger, we intend to expand our
current clusters through the acquisition of properties and target for purchase
other small to mid-sized MSAs and strategic RSAs that we believe are
undervalued or underdeveloped or that possess traits indicative of potentially
high cellular usage and superior financial
 
                                       31
<PAGE>
 
performance. There can be no assurance, however, that we will seek to acquire
or be successful in acquiring any of these systems. Increased competition for
acquisition candidates could result in fewer acquisition opportunities for us
and higher acquisition prices. The magnitude, timing and nature of future
acquisitions will depend upon various factors, including the availability of
suitable acquisition candidates, competition with other telecommunications
companies for suitable acquisitions, the negotiation of acceptable terms, our
financial capabilities, the availability of skilled employees to manage the
acquired companies and general economic and business conditions.
 
      We face risks that the systems we own and those we acquire in the future
will not perform as expected and that such systems will not generate the
returns necessary to repay the indebtedness incurred to acquire, or fund the
capital expenditures needed to develop, the systems. In addition, expansion of
our operations may place a significant strain on our company's management,
financial and other resources. Our ability to manage future growth will depend
upon our ability to monitor operations, control costs, maintain effective
quality controls and significantly expand our internal management, technical
and accounting systems, all of which will result in higher operating expenses.
A failure to expand these areas or to implement and improve such systems,
procedures and controls in an efficient manner and at a pace consistent with
the growth of our business could have a material adverse effect on our
business, prospects, operating results and ability to service our indebtedness,
including the notes.
 
      In addition, we will incur considerable expenses to integrate acquired
systems with existing operations before we earn any anticipated revenue from
these systems, which may cause our operating results to fluctuate
substantially. We will, among other things, have to integrate switching,
transmission, technical, sales, marketing, billing, accounting, quality
control, management, personnel, payroll, regulatory compliance and other
systems and operating hardware and software, some of which may be incompatible
with our existing systems. In addition, telecommunications providers generally
experience higher customer and employee turnover rates during and after an
acquisition. We cannot assure you that we will be able to successfully
integrate the systems we own or may acquire or any other businesses we may
acquire or that any such acquired business will not experience high employee or
customer turnover rates after such acquisition.
 
      We may fail or be unable to discover certain liabilities, including
liabilities arising from non-compliance with certain federal, state or local
environmental laws by prior owners, when we perform due diligence
investigations on each company or business we seek to acquire. We may be
responsible for these liabilities (which may be material) as a successor owner.
We generally seek to minimize our exposure to such liabilities by obtaining
indemnification from each seller of the acquired companies and, in some cases,
by deferring payment of a portion of the purchase price to support these
indemnification obligations. However, we cannot assure you that we could
enforce or collect such indemnifications, even if obtainable, or that the
indemnifications would be sufficient in amount, scope or duration to fully
offset the possible liabilities arising from the acquisitions.
 
      We expect to finance acquisitions with cash on hand, through issuances of
debt or equity securities and through borrowings under credit arrangements,
including pursuant to the credit facility. There is no assurance that we will
be able to obtain additional financing in order to finance our acquisition
strategy. The ability to obtain debt or equity financing is subject to market
conditions and our current debt instruments limit our ability to incur
additional indebtedness. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
Rapid Technological Changes
 
      Telecommunications providers face rapid and significant changes in
technology. Certain new technologies may be protected by patents or other
intellectual property laws and therefore may not be available. In particular,
the wireless telecommunications industry is experiencing significant
technological change, such as the increasing pace of digital upgrades in
existing analog wireless systems, evolving industry standards, the
 
                                       32
<PAGE>
 
allocation of new radio frequency spectrum in which to license and operate
wireless services, ongoing improvements in the capacity and quality of digital
technology, shorter development cycles for new products and enhancements, and
changes in end-user requirements and preferences. Like others in the industry,
we are uncertain about the extent of customer demand as well as the extent to
which airtime and monthly access rates may continue to decline. We cannot
predict the effect of technological changes on our business, and it is possible
that technological developments will have a material adverse effect on us.
 
Potential for Adverse Regulatory Change and Need for Regulatory Approvals
 
Wireless
 
      The FCC regulates the licensing, construction, operation, acquisition and
sale of commercial wireless communications systems, as well as the number of
wireless licensees permitted in each market. Certain aspects of cellular
operations may also be subject to public utility regulation in the state in
which the service is provided. Changes in the regulation of commercial wireless
services (such as cellular, PCS, or paging), wireless carriers, the licensing
of additional connecting carriers in our service areas, the deregulation of
interconnection arrangements or the loss of any license or licensed area
previously awarded to us could have a material adverse effect on our
operations. See "Business--Regulation."
 
      The FCC continues to license additional spectrum for the provision of
wireless communications. In addition, all cellular and PCS licenses in the
United States are subject to renewal upon the expiration of their initial ten-
year term. Our company's initial cellular licenses have expired and will
continue to expire in the near future. To date, however, we have successfully
renewed each of our cellular licenses. We will continue to apply for renewal of
our licenses in a timely fashion. Although we cannot assure you that these
licenses will be renewed, we believe that each license will be renewed based
upon FCC rules establishing a presumption in favor of licensees that have
complied with their regulatory obligations during the prior license term. Any
failure to renew our licenses would have a material adverse effect on our
business, financial condition and results of operations.
 
      We must obtain a number of other approvals, licenses and permits in the
operation of our business, including determinations of no hazard to navigation
from the Federal Aviation Administration in connection with the construction of
cellular and PCS towers. Additionally, the wireless communications industry is
subject to certain state and local government regulation. Operating costs are
also affected by other governmental actions that are beyond our control. We
cannot assure you that the various federal, state and local agencies
responsible for granting licenses, approvals and permits will do so or that,
once granted, will not revoke or fail to renew them. The absence of such
licenses, approvals and permits would adversely affect our existing operations
and could delay commencement of or prohibit business operations that we
propose.
 
      In addition, the Communications Act of 1934, as amended (the
"Communications Act"), generally prohibits foreign persons or entities from
controlling FCC licenses or holding interests of more than 25% in an FCC
licensee. An FCC licensee may, however, request that the FCC allow a foreign
entity to hold more than a 25% interest. These restrictions could adversely
affect our ability to attract additional equity financing.
 
      The wireless communications industry is subject to continually evolving
regulation. As new regulations are promulgated, we may be required to modify
our business plans or operations in order to comply with any such regulations.
There can be no assurance that we can do so in a cost-effective manner, if at
all.
 
      In Puerto Rico, we are also subject to regulation by the Puerto Rico
Planning Board, the Administration of Regulation and Permits and the Puerto
Rico Telecommunications Regulatory Board. The powers of these authorities
include a number of matters, such as cost-based rate-making that could have a
material adverse effect on our business, financial condition and results of
operations.
 
                                       33
<PAGE>
 
Wireline
 
      Lambda CLEC is subject to the Puerto Rico Telecommunications Act of 1996,
which grants jurisdiction over telecommunications services and providers to the
Puerto Rico Telecommunications Regulatory Board and purports to open the Puerto
Rico telecommunications market to competition.
 
      In addition, Lambda CLEC is subject to the Communications Act. Pursuant
to the Communications Act, the FCC requires all telecommunications carriers,
including Lambda CLEC, to contribute to the federal universal service fund. The
Communications Act also requires state public utilities commissions and/or the
FCC to implement policies that mandate reciprocal compensation between local
exchange carriers. On August 1, 1996, the FCC adopted rules implementing these
policies, but various aspects of the order have been overturned by a federal
court and the decision remains subject to further judicial review.
 
General
 
      From time to time, federal, state or commonwealth legislators propose
legislation that potentially could materially affect us either beneficially or
adversely. We cannot assure you that federal, state or commonwealth governments
will not enact legislation or that the FCC, state or commonwealth regulatory
authorities will not promulgate regulation or take other actions that might
have a material adverse affect on our business. If the FCC allocates radio
spectrum for services that compete with our business, these changes could
materially and adversely affect our business, prospects, operating results or
ability to service our indebtedness, including the notes.
 
Fluctuations in Market Value of Our Licenses
 
      A substantial portion of our assets consists of our interests in cellular
licenses held by subsidiaries. While there currently exists a market for the
purchase and sale of cellular licenses, including those in our markets, such a
market may not exist in the future or the values of our licenses in such a
market may fall. The future value of our interests in our cellular licenses
will depend significantly upon the success of our business. The transfer of
interests in such licenses is subject to prior FCC approval, which may have the
effect of reducing the value of the license. As a consequence, if the market
value of our cellular licenses decreases significantly, we may realize a
material loss upon the sale of any of our licenses.
 
Risks Associated with Regional Economic Conditions
 
      Our success depends upon various factors related to business and economic
conditions and consumer spending in the regions where our principal operations
are located. If existing economic conditions were to deteriorate in any of our
regions, the market for cellular services to business and consumer subscribers
may grow more slowly or may decline, thereby materially and adversely affecting
our business and results of operations. The fact that we have clustered our
operations geographically may increase this risk.
 
Risks Associated with Conditions in Puerto Rico
 
      Our business in Puerto Rico is dependent on the business and economic
conditions and consumer spending generally in Puerto Rico. If existing economic
conditions in Puerto Rico were to deteriorate, the market for wireless or
wireline services in Puerto Rico may grow more slowly or decline. This would
have an adverse impact on our business in Puerto Rico and, because our Puerto
Rico operations currently generate approximately 25% of our company's EBITDA,
on our financial condition and results of operations generally.
 
      In particular, our business in Puerto Rico may be materially adversely
affected by events such as hurricanes, labor strikes and the like which affect
Puerto Rico generally. Puerto Rico was hit by Hurricane Georges in September
1998. The island suffered significant damage as a result of the storm. Less
than 10% of
 
                                       34
<PAGE>
 
our PCS towers and microwave transmitters were damaged during the hurricane,
which interrupted service to approximately 25% of our customers in Puerto Rico.
After consideration of expected insurance recoveries, the Company believes it
will not incur significant losses as a result of the effects of the damage
caused by Hurricane Georges. During the three months ended November 30, 1998,
the Company recorded approximately $1.6 million of insurance recoveries related
to subscriber refunds within revenue. Other hurricanes or adverse weather
conditions that may hit the island from time to time may have a material
adverse effect on our business in Puerto Rico.
 
      Any change in Puerto Rico's political status with the U.S., or the
ongoing debate on such status, could also affect the economy of Puerto Rico.
The ultimate effect of possible changes in Puerto Rico's governmental and
political status is uncertain and, accordingly, we cannot assure you that such
changes will not materially adversely affect our business and results of
operations.
 
Operating Costs Due to Fraud
 
      Like most companies in the cellular industry, we incur costs associated
with unauthorized use of our network. Fraud increases interconnection costs,
capacity costs, administrative costs, costs incurred for fraud prevention and
payments to other carriers for unbillable fraudulent roaming. We currently
employ anti-fraud measures in our rural cellular clusters and intend to
continue to develop and invest in measures to prevent cellular fraud. Even so,
we cannot assure you that we will not incur substantial costs due to fraud. In
addition, while we have not experienced significant costs in the past due to
our anti-fraud measures and the costs associated with unauthorized use of our
cellular network, we cannot assure you that these costs will not become
substantial in the future.
 
      We have not yet experienced any fraud problems in connection with our
wireless service in Puerto Rico because of its use of CDMA technology. We
cannot assure you, however, that a fraud problem will not develop or that we
will not incur substantial costs due to fraud in the future.
 
Risk Related to Strategy to Reduce Roaming Rates
 
      We earn much of our revenue from customers of other cellular providers
who are roaming in our markets. Roaming rates per minute pursuant to reciprocal
roaming arrangements have declined over the last several years and we expect
that such declines will continue for the foreseeable future. We have
implemented a strategy of aggressively pricing roaming rates to encourage other
cellular and PCS providers to include portions of our service areas within
their home calling regions and to discourage wireless providers from expanding
their footprints into our service areas. While we benefit from lower roaming
rates when we remit to other cellular providers roaming charges incurred by our
subscribers in other cellular providers' calling regions, we receive less
revenue per minute of use from customers roaming in our markets. We cannot
assure you that the decline in roaming rates will be offset by the benefits of
increased roaming minutes of use by other cellular and PCS providers or that
such decline will not materially adversely affect our results of operations.
 
Possible Inability to Purchase Notes upon a Change of Control
 
      Upon certain change of control events, each holder of notes may require
us to repurchase all or a portion of its notes at a purchase price equal to
101% of the principal amount thereof, plus accrued interest. Our ability to
repurchase the notes upon a change of control event will be limited by the
terms of our debt agreements. Upon a change of control event, we may be
required immediately to repay the outstanding principal, any accrued interest
on and any other amounts owed by us under our Credit Facility or the Mezzanine
Financing. There can be no assurance that we would be able to repay amounts
outstanding under our Credit Facility or obtain necessary consents under such
facility to repurchase these notes. Any requirement to offer to purchase any
outstanding notes may result in us having to refinance our outstanding
indebtedness, which we may not be able to do. In addition, even if we were able
to refinance such indebtedness, such
 
                                       35
<PAGE>
 
financing may be on terms unfavorable to us. The term "Change of Control" is
defined in the section "Description of the New Notes--Certain Definitions."
 
Pledge of Stock by Centennial Cellular Operating
 
      Centennial Cellular Operating has pledged as security the shares of all
its direct and indirect subsidiaries (other than foreign subsidiaries) to the
lenders under the Credit Facility. The pledge of such shares could impair our
ability to obtain future financing on favorable terms, if at all. Further, in
the event Centennial Cellular Operating were to default on its obligations
under the Credit Facility and the lenders were to foreclose upon such pledged
capital stock, Centennial Cellular Operating, as the holding company for such
subsidiary, would likely be unable to service or repay its indebtedness,
including the notes. See "Description of Certain Indebtedness."
 
Risks Related to Co-Obligor; Guarantee by Centennial Under Credit Facility
 
      Centennial, which is a co-obligor of the Notes, has no assets other than
the stock of Centennial Cellular Operating. Therefore, Centennial would be
unlikely to be able to make payments on the notes if Centennial Cellular
Operating fails to make such payments. In addition, Centennial is not be
subject to the covenants of the indenture governing the notes before or after
the Merger.
 
      Centennial has unconditionally guaranteed all obligations of its
subsidiary, Centennial Cellular Operating, which is the borrower under the
credit facility. In the event that Centennial Cellular Operating were to
default on its obligations under the Credit Facility and the lenders were to
seek to enforce such guarantee, Centennial would likely be unable to service or
repay its indebtedness, including the notes. See "Description of Certain
Indebtedness."
 
Changes in Tax Law
 
      Section 936 of the Internal Revenue Code of 1986 was amended in 1996.
This section had historically provided tax incentives for U.S. companies to
operate in Puerto Rico and to reinvest the earnings from their Puerto Rico
operations in Puerto Rico. One result of this tax preference was to encourage
the development of business and manufacturing operations in Puerto Rico and to
make available to certain Puerto Rico businesses financing at rates below those
generally offered by commercial banks. As a result of the 1996 amendment to
Section 936, such favorable financing rates are no longer available.
 
      The tax benefits available to corporations, such as pharmaceutical
companies, doing business in Puerto Rico phase out in annual increments through
2005. Consequently, such corporations may reduce or close their Puerto Rico
operations and may reduce their re-investments in Puerto Rico. The changes may
also reduce the incentives for new investments in Puerto Rico. We do not yet
know the full extent to which our business in Puerto Rico will be affected by
such changes in the tax law. However, if the change diminishes the overall
level of business activity in Puerto Rico, it could cause our company's
business customers and other cellular subscribers roaming within our coverage
area to reduce their telecommunications usage. A significant reduction in such
usage would have a material adverse effect on our business and results of
operations.
 
Bankruptcy Risks Related to Escrow and Pledge Account
 
      If we or any of our subsidiaries commence a bankruptcy or reorganization
case, or one is commenced against us, the bankruptcy law may prevent the
trustee under the indenture governing the notes from foreclosing on and selling
the escrow funds if an event of default on the notes occurs. Under applicable
bankruptcy law, secured creditors such as the holders of the notes are
prohibited from foreclosing upon or disposing of a debtor's property without
prior bankruptcy court approval. See "Description of the New Notes--Security."
 
                                       36
<PAGE>
 
Fraudulent Conveyance
 
      We believe that we incurred the indebtedness represented by the notes for
proper purposes and in good faith. Based on current asset valuations and other
financial information, we also believe that we were solvent after issuing the
notes, consummating the Merger and completing the other financings required for
the Merger. We expect that we will have sufficient capital to carry on our
business and to pay our debts as they mature. See "--Significant Indebtedness
and Interest Payment Obligations." Notwithstanding this belief, however, if an
unpaid creditor or a representative of a creditor (such as a trustee in
bankruptcy or a debtor-in-possession) were to sue us in an appropriate court,
the court might find that, when we issued the notes,
 
  (i) we incurred the indebtedness with intent to hinder, delay or defraud
      any present or future creditor or we contemplated insolvency with a
      design to prefer one or more creditors to the exclusion in whole or in
      part of others; or
 
  (ii) we incurred the indebtedness for less than reasonably equivalent value
       and, at the time, we
 
     .  were insolvent,
 
     .  were rendered insolvent by reason of such incurrence,
 
     .  were engaged in a business or transaction for which our remaining
        assets constituted unreasonably small capital,
 
     .  intended to incur, or believed that we would incur, debts beyond
        our ability to pay such debts as they matured or
 
     .  were a defendant in an action for money damages or had a judgment
        for money damages docketed against us (in either case, if after
        final judgment, the judgment remained unsatisfied).
 
      In such event, the court could, among other things, (x) void all or a
portion of our obligations to you, the effect of which would be that you may
not be repaid in full and/or (y) subordinate our obligations to you to our
other existing and future indebtedness to a greater extent than would otherwise
be the case, the effect of which would entitle such other creditors to be paid
in full before any payment could be made on the notes. We cannot assure you
that, after providing for all prior claims, there would be sufficient assets to
satisfy the claims of holders of the notes.
 
      Courts applying the laws of different jurisdictions will use different
standards to determine whether we are insolvent for purposes of the foregoing.
Generally, however, a company would be considered insolvent for purposes of the
foregoing if the sum of the company's debts is greater than all of the
company's property at a fair valuation, or if the present fair saleable value
of the company's assets is less than the amount that will be required to pay
its probable liability on its existing debts as they become absolute and
mature. We cannot predict what standards a court would apply to determine
whether we were solvent at the relevant time.
 
Potential Failure of Computer Systems to Recognize Year 2000
 
      During fiscal 1998, we began a review of our computer systems and related
software to identify systems and software that might malfunction due to a
misidentification of the Year 2000. Most of our customer-related computer
systems and databases, including our billing systems, are managed by third
parties under contractual arrangements. We have requested those third parties
to advise us as to whether they anticipate difficulties in addressing Year 2000
problems and, if so, the nature of such difficulties. Our management has not
finally determined the cost associated with its Year 2000 readiness efforts and
the related potential impact on our results of operations. Amounts expended to
date have not been material. We cannot assure you that the systems of other
companies on which we rely, including third party billers, will be converted in
time or that any such failure to convert by another company will not have a
material adverse effect on our business, financial condition or results of
operations.

Risks Associated With Certain Changes in Senior Management
 
      Michael J. Small, who became the Chief Executive Officer of Centennial
upon the consummation of the Merger, has 17 years of experience in the
telecommunications industry but has no experience managing our operations. We
will not have employment contracts with senior management personnel other than
Mr. Small, whose contract expires on September 30, 2002; Rudy J. Graf, who is
the Chief Operating Officer pursuant to a new employment contract that expires
on May 31, 1999; Peter Chehayl, who became Vice President and Chief Financial
Officer following the Merger; and Edward G. Owen, who became Vice President--
Corporate Development following the Merger. To the extent that these key
individuals do not remain with Centennial at the end of their respective
employment terms, such change in management could have a material adverse
effect on our company unless we can obtain a suitable replacement in a timely
manner. Our management will also be required to devote additional time and
resources toward recruitment, hiring and training to fill such positions,
which, if substantial, could result in a material adverse effect on our
business, prospects, operations or results of operations. If the senior
management team is not put into place, or if our executive officers do not
achieve their management objectives in a timely manner, our business,
prospects, operating results and ability to service our indebtedness, including
the notes, may be materially adversely affected.
 
Control by the Equity Investors
 
      Following the Merger, 92.9% of Centennial's outstanding Common Shares are
held by WCAS VIII, certain of its affiliates and certain other equity
investors. Accordingly, these equity investors will, directly or indirectly,
control our company and have the power to elect all of our directors, appoint
new management and approve or reject any action requiring the approval of
stockholders, including adopting amendments to our charter and approving
mergers and sales of all or substantially all of our assets. In addition, the
existence of a controlling stockholder may have the effect of making it
difficult for a third party to acquire, or of discouraging a third party from
seeking to acquire, a majority of the outstanding Common Shares of Centennial.
See "Principal Stockholders" and "Certain Relationships and Related
Transactions--Equity Investor Agreements."
 
Investment Interests; Capital Calls
 
      We have a limited ability to direct the operation of any system in which
we now or in the future hold a minority investment as a limited partner. In
addition, these investment partnerships are entitled to make certain demands
for capital contributions, including to complete acquisitions by the limited
partnerships. If we do not meet such a capital call, our ownership interest in
such system may be diluted. Capital calls with respect to such investment
interests for the fiscal years ended May 31, 1998, 1997 and 1996 were
approximately $0.8 million, $2.9 million and $1.5 million, respectively. We
have, to date, paid all capital calls that we have received. Although we
anticipate that such capital calls will decrease over time, we cannot assure
you that such capital calls will, in fact, decrease. We cannot assure you that
we will be able to pay such capital calls when due. In addition, under the
indenture relating to the notes, we will be permitted to dividend to
Centennial, our parent company, all cash received from our non-subsidiary
investment interests.
 
Equipment Failure; Natural Disaster
 
      A major equipment failure or a natural disaster affecting any one of our
central switching offices or certain of our cell sites or microwave links could
have a material adverse effect on our business, prospects, operating results or
ability to service our indebtedness, including the notes. In particular, our
business in Puerto Rico may be materially adversely affected by events such as
hurricanes, labor strikes and the like which affect Puerto Rico generally.
Puerto Rico was hit by Hurricane Georges in September 1998 and the island
suffered significant damage as a result of the storm. After giving effect to
insurance proceeds that we expect to receive, there will be no material adverse
impact on our Company's operating results. Other hurricanes or adverse weather
conditions that may hit the island from time to time may have a material
adverse effect on our business
 
                                       38
<PAGE>
 
in Puerto Rico. Although we currently carry "business interruption" insurance
and expect to carry similar insurance following the Merger, our insurance
policies may not entirely cover all damages we may suffer.
 
Radio Frequency Emission Concerns
 
      Media reports have suggested that certain radio frequency ("RF")
emissions from portable cellular telephones may be linked to cancer and
interfere with heart pacemakers and other medical devices. Concerns over RF
emissions and interference may have the effect of discouraging the use of
cellular telephones, which could have an adverse effect upon our business.
During the past two years, the FCC has updated its guidelines and methods for
evaluating the environmental effects of RF emissions. The updated guidelines
generally are more stringent than the previous rules, based on recommendations
of federal health and safety agencies, including the Environmental Protection
Agency and the Food and Drug Administration. However, we do not believe these
guidelines will have a material impact on our operations. Among the guidelines
are limits for specific absorption rate for evaluation of certain hand-held
devices such as cellular telephones, as well as guidelines for the evaluation
of cellular transmitting facilities. We believe that the cellular telephones
currently marketed and generally used, as well as our transmission facilities,
comply with the new standards. Moreover, the FCC preempted state and local
government regulation of cellular and other personal wireless services
facilities based on RF environmental effects to the extent that such facilities
comply with the FCC's rules concerning such RF emissions. Potential
interference to medical devices involves primarily digital transmissions rather
than analog. Industry, government and medical experts have been conducting
tests and developing methods for reducing or eliminating such interference.
 
Information Provided to WCAS VIII
 
      This Prospectus contains projections that were prepared in June 1998 and
which we included herein solely because they were shown to WCAS VIII prior to
Acquisition's entering into the Merger Agreement and because they were included
in the registration statement on Form S-4 filed in connection with the Merger.
None of WCAS VIII, the Initial Purchasers or their affiliates prepared the
projections or expect them to be achieved. WCAS VIII has informed us that, in
its judgment, it does not expect the projected results to be achieved and,
accordingly, it did not rely on the projections in negotiating the Merger
Agreement. The projections have not been updated since June 1998 and we do not
intend to update the projections publicly. The projections were not prepared
with a view toward complying with the guidelines established by the American
Institute of Certified Public Accountants with respect to prospective financial
information. Accordingly, prospective investors in the notes are cautioned not
to place any reliance on the projections. See "Forward-Looking Statements."
 
      We have also informed WCAS VIII that our internal financial forecasts
(upon which the projected financial performance provided to WCAS VIII was based
in part) are, in general, prepared solely for internal use and capital
budgeting and other management decision-making purposes and are subjective in
many respects and thus susceptible to various interpretations and periodic
revision based on actual experience and business developments. Projected
information of this type is based on estimates and assumptions that are
inherently subject to significant economic and competitive uncertainties and
contingencies, all of which are difficult to predict and many of which are
beyond our control, or the control of WCAS VIII and its financial advisors.
Many of the assumptions upon which the foregoing projected financial
performance was based, none of which were approved by WCAS VIII, Acquisition or
the Initial Purchasers, are dependent upon economic forecasting (both general
and specific to our businesses), which is inherently uncertain and subjective.
ACCORDINGLY, THERE CAN BE NO ASSURANCE THAT FORECASTED RESULTS ARE INDICATIVE
OF OUR FUTURE PERFORMANCE OR THAT ACTUAL RESULTS WILL NOT BE MATERIALLY HIGHER
OR LOWER THAN THOSE FORECASTED. INCLUSION OF THE PROSPECTIVE FINANCIAL
INFORMATION IN THIS PROSPECTUS SHOULD NOT BE REGARDED AS A REPRESENTATION BY
ANY PERSON THAT THE FORECASTED RESULTS WILL BE ACHIEVED. None of WCAS VIII,
Acquisition, our company, the Initial Purchasers or their respective financial
advisors assumes any
 
                                       39
<PAGE>
 
responsibility for the ultimate outcome of any of such projections. Inclusion
of the foregoing projections should not be regarded as an indication that WCAS
VIII, Acquisition, our company, the Initial Purchasers or any other person who
received such information considers it an accurate prediction of future events.
 
Absence of Public Market for the New Notes
 
      The New Notes are being offered to the holders of the Old Notes. The Old
Notes were sold to the Initial Purchasers on December 14, 1998 and then resold
to "qualified institutional buyers" (as defined in Rule 144A under the
Securities Act) and pursuant to offers and sales outside the United States
within the meaning of Regulation S under the Securities Act and are eligible
for trading in the Private Offerings, Resale and Trading through Automated
Linkages (PORTAL) market. The New Notes are securities for which there
currently is no market. If the New Notes are trades, they may trade at a
discount from their face value, depending upon prevailing interest rates, the
market for similar securities and other factors. The Company and Centennial
Cellular Operating do not intend to apply for listing of the New Notes on any
securities exchange or the Nasdaq National Market. Accordingly, there can be no
assurance as to the development or liquidity of any trading market for the New
Notes.
 
      Historically, there has been substantial volatility in the market for
non-investment grade debt, such as the notes, due to market disruptions. This
volatility has increased in recent months and the liquidity of non-investment
grade securities has declined significantly. We cannot assure you that the
market, if any, for the notes will not be subject to similar disruptions. Any
such disruptions may have a material adverse effect on the holders of the
notes.
 
Consequences of the Exchange Offer to Non-Tendering Holders of the Old Notes
 
      In the event the Exchange Offer is consummated, the Company and
Centennial Cellular Operating will not be required to register the Old Notes
under the Securities Act. In such event, the New Notes would rank pari passu
with the Old Notes, and the holders of Old Notes seeking liquidity in their
investment would have to rely on exemptions from registration requirements
under the securities laws, including the Securities Act. A reduction of the
aggregate principal amount of the Old Notes outstanding as a result of the
consummation of the Exchange Offer may have an adverse effect on the ability of
holders of the Old Notes to transfer such Old Notes.

                                   THE MERGER
 
      The following is a summary of the structure of the Merger that was
consummated on January 7, 1999. This summary does not purport to be complete
and is qualified in its entirety by reference to the Merger Agreement, a copy
of which has been filed with the Commission.
 
Structure of the Merger
 
      Pursuant to the Merger Agreement and subject to the terms and conditions
set forth therein, Acquisition merged with and into Centennial and Centennial
was the surviving corporation in the Merger. At the effective time of the
Merger, by virtue of the Merger,
 
  .  each issued and outstanding share of Class A Common Stock, par value
     $.01 per share, of Centennial was converted into the right to receive,
     subject to proration so that the aggregate number of common shares of
     the surviving corporation received by the holders of Common Shares is
     equal to 7.1% of the common shares of the surviving corporation
     outstanding immediately after the effective time of the Merger, either
     (a) one common share of the surviving corporation or (b) $41.50 in cash
     (the "Cash Merger Consideration");
 
  .  all outstanding shares of Class B Common Stock, par value $.01 per
     share, were converted into the right to receive the Cash Merger
     Consideration; and
 
  .  all outstanding shares of Convertible Preferred Stock and Second Series
     Convertible Preferred Stock of Centennial were converted into the right
     to receive the Cash Merger Consideration on an as-converted basis.
 
      The surviving corporation in the Merger continues to operate under the
name "Centennial Cellular Corp."
 
Financing of the Merger
 
      A total of approximately $1.87 billion was required to pay the cash
consideration to Centennial stockholders in the Merger, repay the Company's
indebtedness (including the purchase of Tendered Notes in the Debt Tender
Offers), pay the related fees and expenses and purchase the Pledged Securities.
See "Summary--The Merger--Sources and Uses of Funds." The sources of funding
for the Merger and the related transactions were the Credit Facility, the
Mezzanine Financing, the Common Equity Contribution and the Offering of the Old
Notes (collectively, the "Merger Financing").
 
      In connection with the Merger, Centennial Cellular Operating and its
Puerto Rico subsidiary borrowed approximately $936.0 million under the $1,050
million Credit Facility. A group of lenders provided Centennial Cellular
Operating with the Credit Facility, consisting of an $900 million term loan
facility and a $150 million revolving credit facility. See "Description of
Certain Indebtedness."
 
      WCAS Capital Partners III, L.P., an investment partnership affiliated
with WCAS VIII, purchased, at the time of the consummation of the Merger,
unsecured subordinated notes due 2009 of Centennial and common shares of
Centennial at an aggregate price of $180 million. In addition, the other Equity
Investors made a Common Equity Contribution of $400 million to purchase Common
Shares at the time of the consummation of the Merger. In total, the Equity
Investors owned 9,638,554 Common Shares immediately following the consummation
of the Merger (prior to giving effect to a three-for-one stock split effected
on January 8, 1999).

Debt Tender Offers and Solicitations
 
      In connection with the Merger, Centennial consummated the Debt Tender
Offers to acquire approximately 99% of its outstanding Tendered Notes and to
eliminate the interest expense associated with the Old Notes. Pursuant to
consent solicitations which were made in order to enhance the operating and
financial flexibility of the Company, Centennial entered into supplemental
indentures, approved by the required number of holders of the Tendered Notes,
to eliminate most of the restrictive covenants contained in the indentures
governing the Tendered Notes and to amend certain other provisions contained in
such indentures. As of the expiration date of the Debt Tender Offers, valid
irrevocable tenders and consents had been received from 99.4% of holders of the
2001 Notes and 99.8% of holders of the 2005 Notes. From time to time in the
future, Centennial or its affiliates may seek to acquire any Tendered Notes
that remain outstanding following the consummation the Debt Tender Offers,
through open market purchases, privately negotiated transactions, tender
offers, exchange offers or otherwise, upon such terms and at such prices as it
may determine, which may be more or less than the price to be paid pursuant to
the related Debt Tender Offer and could be for cash or other consideration. In
addition, the Company may elect to redeem or defease any Tendered Notes that
remain outstanding in accordance with the terms of the applicable Tendered Note
indenture.

<PAGE>
 
                                USE OF PROCEEDS
 
      The Company and Centennial Cellular Operating will not receive any
proceeds from the issuance of New Notes pursuant to the Exchange Offer. The
Offering resulted in net proceeds to the Company, as the successor to
Centennial Finance Corp., and Centennial Cellular Operating of approximately
$353.6 million (after payment of underwriting discounts and other issuance
costs aggregating approximately $16.5 million). The net proceeds from the
Offering, the Mezzanine Financing and the Common Equity Contribution, together
with borrowings under the Credit Facility, were used to (i) fund payment of the
cash consideration in the Merger, (ii) repay or repurchase certain indebtedness
of Centennial (including the Tendered Notes purchased in the Debt Tender
Offers), (iii) pay the fees and expenses incurred in connection with the
Merger, the Merger Financings and the other transactions contemplated by the
Merger Agreement, and (iv) purchase the pledged securities.
 
      The following table sets forth the sources and uses of funds in
connection with the financing of the Merger as of the Merger's consummation on
January 7, 1999:

(1) The Credit Facility consists of three term loans in aggregate principal
    amount of $900 million and a revolving credit facility in an aggregate
    principal amount of up to $150 million. The borrowers under these
    facilities are Centennial Cellular Operating and, for a portion thereof,
    Centennial de Puerto Rico. Centennial, together with the direct and
    indirect subsidiaries of Centennial Cellular Operating (excluding initially
    Centennial de Puerto Rico and its subsidiaries, which subsidiaries have
    guaranteed the obligations of Centennial de Puerto Rico under the Credit
    Facility), have unconditionally guaranteed, jointly and severally, the
    obligations of the borrowers under such facilities. See "Description of
    Certain Indebtedness."
 
(2) Upon consummation of the Merger, approximately $57.5 million of the
    proceeds from the Old Notes was deposited with the Trustee to purchase
    pledged securities to pay the first three scheduled interest payments on
    the Notes at the stated interest rate. See "Description of the New Notes--
    Security."
 
(3) WCAS Capital Partners III, L.P., an investment partnership affiliated with
    WCAS VIII, purchased, at the time of the consummation of the Merger,
    unsecured subordinated notes due 2009 and common shares of Centennial at an
    aggregate price of $180 million. The issuance of $180 million principal
    amount of Mezzanine Financing has been allocated as $157.5 million debt and
    $22.5 million equity.
 
                                       43

(4) Includes $1,033.1 million in consideration for the Common Shares, $128.2
    million in consideration for the Common Shares issued upon conversion of
    Centennial's preferred stock and $42.3 million in consideration for the
    settlement of outstanding options to purchase Common Shares.
 
(5) Represents the amount of debt tender offer payments and funds required to
    repay total existing indebtedness of Centennial. In connection with the
    Merger, Centennial consummated the Debt Tender Offers to acquire its
    outstanding 8 7/8% Senior Notes due 2001 and 10 1/8% Senior Notes due 2005.
    At the expiration of the Debt Tender Offers, Centennial paid consent
    solicitation fees and tender offer payments to 99.4% of holders of the 2001
    Notes and 99.8% of holders of the 2005 Notes. The amount required to repay
    existing indebtedness and preferred dividends accrued of Centennial and the
    Notes includes accrued interest of $2.3 million and preferred dividends of
    $16.4 million, less cash on hand, which was approximately $18.7 million.
 
(6) The amount required to pay the debt tender premiums associated with the
    debt tender offers for the outstanding notes. The amount shown above
    includes the consent solicitation fees associated with the debt tender
    offers.

    expenses related to the Merger, this Offering and the transactions
    contemplated thereby.

                               THE EXCHANGE OFFER
 
Terms of the Exchange Offer
 
      The holders of the Old Notes currently are entitled to certain
registration rights under the Registration Rights Agreement. Pursuant thereto,
the Company and Centennial Cellular Operating became obligated to file with the
Commission a registration statement covering the offer by the Company and
Centennial Cellular Operating to the holders of the Old Notes to exchange all
of the Old Notes for the New Notes. The Exchange Offer being made hereby, if
consummated, will satisfy the Company's and Centennial Cellular Operating's
obligations under the Registration Rights Agreement.
 
      Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal, the Company and Centennial
Cellular Operating will accept all Old Notes properly tendered and not
withdrawn prior to 5:00 p.m., New York City time, on the Expiration Date. The
Company will issue $1,000 principal amount of New Notes in exchange for each
$1,000 principal amount of outstanding Old Notes accepted in the Exchange
Offer. Holders may tender some or all of their Old Notes pursuant to the
Exchange Offer.
 
      Based on an interpretation by the staff of the Commission set forth in
no-action letters issued to third parties, the Company believes that the New
Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale, resold and otherwise transferred by the holders thereof
(other than any such holder that is an "affiliate" of the Company within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such New Notes are acquired in the ordinary course of such holders'
business, and such holders have no arrangement with any person to participate
in the distribution of such New Notes. See Morgan Stanley & Co., Inc., SEC No-
Action Letter (available June 5, 1991), Exxon Capital Holdings Corporation, SEC
No-Action Letter (available May 13, 1988), and Shearman & Sterling, SEC No-
Action Letter (available July 2, 1993).
 
      If any person were to be participating in the Exchange Offer for the
purposes of distributing securities in a manner not permitted by the
Commission's interpretation, such person (i) could not rely on the position of
the staff of the Commission enunciated in Exxon Capital Holdings Corporation or
similar interpretive letters and (ii) must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction.
 
      Each broker-dealer that receives New Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. The Letter of Transmittal states
that by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. This Prospectus, as it may be amended or supplemented from time
to time, may be used by a broker-dealer in connection with resales of New Notes
received in exchange for Old Notes where such Old Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. See "Plan of Distribution."
 
      As of the date of this Prospectus, there was $370,000,000 aggregate
principal amount of the Old Notes outstanding. This Prospectus, together with
the Letter of Transmittal, is being sent to all such registered holders as of
the date of this Prospectus.
 
      The Company shall be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given written notice thereof to the Exchange
Agent. The Exchange Agent will act as agent for the tendering holders of Old
Notes for the purposes of receiving the New Notes from the Company and
delivering New Notes to such holders.
 
                                       45
<PAGE>
 
      If any tendered Old Notes are not accepted for exchange because of an
invalid tender, certificates for any such unaccepted Old Notes will be
returned, without expense, to the tendering holder thereof as promptly as
practicable after the Expiration Date.
 
      If Old Notes are not tendered, they shall remain outstanding and shall
continue to accrue interest from their date of issue, December 14, 1998, at a
rate of 10 3/4% per annum.
 
      In the event the Exchange Offer is consummated, the Company will not be
required to register the Old Notes. In such event, holders of Old Notes seeking
liquidity in their investment would have to rely on exemptions to registration
requirements under the securities laws, including the Securities Act. See "Risk
Factors--Consequences of the Exchange Offer to Non-Tendering Holders of the Old
Notes."
 
      The term "Expiration Date" shall mean the expiration date set forth on
the cover page of this Prospectus, unless the Company, in its sole discretion,
extends the Exchange Offer, in which case the term "Expiration Date" shall mean
the latest date to which the Exchange Offer is extended.
 
      In order to extend the Expiration Date, the Company will notify the
Exchange Agent of any extension by written notice and will mail to the record
holders of Old Notes an announcement thereof, each prior to 9:00 a.m., New York
City time, on the next business day after the previously scheduled Expiration
Date. Such announcement may state that the Company is extending the Exchange
Offer for a specified period of time.
 
      In addition, the Company will issue notice of each such extension by
press release or other public announcement as contemplated by the provisions of
Rule 14e-1 promulgated under the Exchange Act.
 
Interest on the New Notes
 
      The New Notes will bear interest from December 14, 1998, payable
semiannually on June 15 and December 15 of each year, commencing June 15, 1999,
at a rate of 10 3/4% per annum.
 
Procedures for Tendering
 
      The tender to the Company of Old Notes by a holder thereof pursuant to
one of the procedures set forth below will constitute an agreement between such
holder and the Company in accordance with the terms and subject to the
conditions set forth herein and in the Letter of Transmittal.
 
      A holder of Old Notes may tender the same by (i) properly completing and
signing the Letter of Transmittal or a facsimile thereof (all references in
this Prospectus to the Letter of Transmittal shall be deemed to include a
facsimile thereof) and delivering the same, together with the certificate or
certificates representing the Old Notes being tendered and any required
signature guarantees, to the Exchange Agent at its address set forth on the
back cover of this Prospectus on or prior to the Expiration Date (or complying
with the procedure for book-entry transfer described below) or (ii) complying
with the guaranteed delivery procedures described below.
 
      If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the New Notes to be issued in exchange therefor are
to be issued (and any untendered Old Notes are to be reissued) in the name of
the registered holder (which term, for the purposes described herein, shall
include any participant in The Depository Trust Company (also referred to as a
book-entry transfer facility) whose name appears on a security listing as the
owner of Old Notes), the signature of such signer need not be guaranteed. In
any other case, the tendered Old Notes must be endorsed or accompanied by
written instruments of transfer in form satisfactory to the Company and duly
executed by the registered holder, and the signature on the endorsement or
instrument of transfer must be guaranteed by a commercial bank or trust company
located or having an office or correspondent in the United States, or by a
member firm of a national securities exchange or of the
 
                                       46
<PAGE>
 
National Association of Securities Dealers, Inc., which firm must also be a
member of or participant in the Securities Transfer Agents Medallion Program,
the New York Stock Exchange Medallion Signature Program or the Stock Exchanges
Medallion Program (any of the foregoing being hereinafter referred to as an
"Eligible Institution"). If the New Notes and/or Old Notes not exchanged are to
be delivered to an address other than that of the registered holder appearing
on the note register for the Notes, the signature in the Letter of Transmittal
must be guaranteed by an Eligible Institution.
 
      The method of delivery of Old Notes and all other documents is at the
election and risk of the holder. If sent by mail, it is recommended that
registered mail, return receipt requested, be used, proper instance be
obtained, and the mailing be made sufficiently far in advance of the Expiration
Date to permit delivery to the Exchange Agent on or before the Expiration Date.
 
      The Exchange Agent will make a request promptly after the date of this
Prospectus to establish accounts with respect to the Old Notes at the book-
entry transfer facility for the purpose of facilitating the Exchange Offer, and
subject to the establishment thereof, any financial institution, that is a
participant in the book-entry transfer facility's system may make book-entry
delivery of Old Notes by causing such book-entry transfer facility to transfer
such Old Notes into the Exchange Agent's account with respect to the Old Notes
in accordance with the book-entry transfer facility's procedures for such
transfer. Although delivery of Old Notes may be effected through book-entry
transfer into the Exchange Agent's accounts at the book-entry transfer
facility, an appropriate Letter of Transmittal with any required signature
guarantee and all other required documents must in each case be transmitted to
and received or confirmed by the Exchange Agent at its address set forth on the
back cover page of this Prospectus on or prior to the Expiration Date, or, if
the guaranteed delivery procedures described below are complied with, within
the time period provided under such procedures.
 
      If a holder desires to accept the Exchange Offer, and time will not
permit a Letter of Transmittal or Old Notes to reach the Exchange Agent before
the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if the Exchange Agent has
received at its office listed on the back cover hereof on or prior to the
Expiration Date a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
names in which the Old Notes are registered and, if possible, the certificate
numbers of the Old Notes to be tendered, and stating that the tender is being
made thereby and guaranteeing that within five New York Stock Exchange trading
days after the date of execution of such letter, telegram or facsimile
transmission by the Eligible Institution, the Old Notes, in proper form for
transfer (or a confirmation of book-entry transfer of such Old Notes into the
Exchange Agent's account at the book-entry transfer facility), will be
delivered by such Eligible Institution together with a properly completed and
duly executed Letter of Transmittal (and any other required documents). Unless
Old Notes being tendered by the above-described method are deposited with the
Exchange Agent within the time period set forth above (accompanied or preceded
by a properly completed Letter of Transmittal and any other required
documents), the Company may, at its option, reject the tender. Copies of a
Notice of Guaranteed Delivery which may be used by Eligible Institutions for
the purposes described in this paragraph are available from the Exchange Agent.
 
      A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at the book-entry transfer
facility) is received by the Exchange Agent, or (ii) a Notice of Guaranteed
Delivery or letter, telegram or facsimile transmission to similar effect (as
provided above) from an Eligible Institution is received by the Exchange Agent.
Issuances of New Notes in exchange for Old Notes tendered pursuant to a Notice
of Guaranteed Delivery or letter, telegram or facsimile transmission to similar
effect (as provided above) by an Eligible Institution will be made only against
deposit of the Letter of Transmittal (and any other required documents) and the
tendered Old Notes.

      All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or irregularity
in the tender of any Old Notes. None of the Company, the Exchange Agent or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give such
notification.
 
      By tendering, each holder will represent to the Company that, among other
things, (i) the New Notes acquired pursuant to the Exchange Offer are being
obtained in the ordinary course of such holder's business, (ii) such holder has
no arrangement with any person to participate in the distribution of such New
Notes, (iii) such holder is not an "affiliate," as defined under Rule 405 of
the Securities Act, of the Company, and (iv) if such holder is a broker or a
dealer (as defined in the Exchange Act), that it acquired the Old Notes for its
own account as a result of market-making activities on other trading activities
and that it has not entered into any arrangement or understanding with the
Company or any "affiliate" of the Company to distribute the New Notes received
in the Exchange Offer.
 
Withdrawal of Tenders
 
      Except as otherwise provided herein, tenders of Old Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
      To withdraw a tender of Old Notes in the Exchange Offer, a written
transmission notice of withdrawal via telegram, telex, facsimile transmission
or letter must be received by the Exchange Agent at its address set forth
herein prior to 5:00 p.m., New York City time, on the Expiration Date. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Old Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to
be withdrawn (including the certificate number or numbers and principal amount
of such Old Notes), (iii) be signed by the Depositor in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the Old
Notes register the transfer of such Old Notes into the name of the depositor
withdrawing the tender, and (iv) specify the name in which any such Old Notes
are to be registered, if different from that of the Depositor. All questions as
to the validity, form and eligibility (including time of receipt) of such
withdrawal notices will be determined by the Company, whose determination shall
be final and binding on all parties. Any Old Notes so withdrawn will be deemed
not to have been validly tendered for purposes of the Exchange Offer, and no
New Notes will be issued with respect thereto unless the Old Notes so withdrawn
are validly retendered. Any Old Notes that have been tendered but that are not
accepted for exchange will be returned to thsoon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. Properly
withdrawn Old Notes may be retendered by following one of the procedures
described above under "Procedures for Tendering" at any time prior to the
Expiration Date.
 
Conditions
 
      The Exchange Offer is not subject to any conditions other than that the
Exchange Offer does not violate applicable law or any applicable interpretation
of the staff of the Commission.

(1) Represents our proportionate share of profits and losses based on our
    interest in earnings of limited partnerships controlled and managed by
    other cellular operators which we account for on the equity method.
 
(2) Represents the percentage share of earnings of our consolidated
    subsidiaries that is allocable to unaffiliated holders of minority
    interests.
 
(3) EBITDA is defined, for any period, as earnings before income from Minority
    Cellular Investment Interests, allocations to minority interests in
    consolidated subsidiaries, interest expense, interest income, income taxes,
    depreciation and amortization and gain on sale of assets. EBITDA is
    presented because it is a widely accepted financial indicator of a
    company's ability to service and/or incur indebtedness. EBITDA should not
    be considered an alternative to net income as a measure of our operating
    results or to cash flow as a measure of liquidity. In addition, although
    the EBITDA measure of performance is not recognized under generally
    accepted accounting principles, it is widely used by various companies as a
    general measure of a company's performance because it assists in comparing
    performance on a relatively
 
                                       52
<PAGE>
 
   consistent basis across companies without regard to depreciation and
   amortization, which can vary significantly depending on accounting methods
   (particularly where acquisitions are involved) or non-operating factors such
   as historical cost bases. Because EBITDA is not calculated identically by
   all companies, the presentation herein may not be strictly comparable to
   other similarly titled measures of other companies.
 
(4) For the purposes of determining the ratio of earnings to fixed charges,
    earnings are defined as earnings before income taxes, minority interest and
    extraordinary items, plus fixed charges. Fixed charges include interest
    expense on all indebtedness, amortization of deferred debt issuance costs
    and one-third of rental expense on operating leases representing that
    portion of rental expense deemed to be attributable to interest. The ratio
    of earnings to fixed charges is less than one-to-one for all periods
    presented and, therefore, earnings are inadequate to cover fixed charges.
    The amount by which earnings exceeded (are less than) fixed charges for the
    six months ended November 30, 1998 and 1997 are $12,188 and $(21,839),
    respectively, and for the years ended May 31, 1998, 1997, 1996, 1995 and
    1994 are $(45,382), $(43,189), $(33,412), $(47,117) and $(39,885),
    respectively.
 
(5) As of period-end.
 
(6) For the years ended May 31, 1995 and May 31, 1994, the number of Net Pops
    is based on 1990 population figures of an MSA or RSA, as derived from the
    1990 U.S. Census data.
 
(7) The penetration rate equals the percentage of total population in our
    service areas who are subscribers to our cellular service as of period-end.
 
(8) ARPU equals total monthly revenue per average subscriber.
 
(9) For the year ended as of the date shown. Determined for each period as
    total marketing cost plus cost of equipment sales (net of associated
    revenue), divided by the total subscriber activations during the fiscal
    year.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
 
      The following pro forma consolidated financial statements have been
derived by the application of pro forma adjustments to the Company's historical
consolidated financial statements included herein. The unaudited pro forma
statement of operations and other unaudited pro forma supplemental financial
information gives effect to (i) the Merger Financings and (ii) the Debt Tender
Offers and the repayment or conversion of all other existing indebtedness of
the Company. The pro forma balance sheet information as of November 30, 1998
has been prepared as if such transactions had occurred on that date, and the
pro forma statement of operations information for the fiscal year ended May 31,
1998 and the six months ended November 30, 1998 has been prepared as if such
transactions had occurred at June 1, 1997. The adjustments are described in the
accompanying notes. The pro forma consolidated financial statements should not
be considered indicative of actual results that would have been achieved had
the Merger and related transactions been consummated on the date or for the
periods indicated and do not purport to indicate balance sheet data or results
of operations as of any future date or for any future period. The pro forma
consolidated financial statements should be read in conjunction with the
Company's historical financial statements and the notes thereto included
herein.
 
      The pro forma adjustments were applied to the respective historical
consolidated financial statements to reflect and account for the Merger as a
recapitalization. Accordingly, the historical basis of the Company's assets and
liabilities will not be affected by the transaction.

  (i) The issuance of $180,000 principal amount of subordinated notes and
      Common Shares for $180,000 in cash in the Mezzanine Financing will be
      allocated as $157,500 debt and $22,500 equity.

(2) Represents the retirement of treasury shares.
 
(3) The adjustments represent the repurchase of Common Shares and preferred
    stock from existing stockholders.
 
(4) The adjustments represent the following:
 
  --Compensation expense of $42,332 ($31,608 after related tax effect)
   related to the repurchase of all outstanding stock options at the
   difference between $41.50 per share and the exercise price of the options,
   assuming the respective option holders agree to such repurchase.
 
  --Compensation expense of $2,638 ($1,635 after related tax effect) related
   to the immediate vesting, at a change of control, of restricted stock
   issued under the Company's 1993 Equity Incentive Plan.
 
(5) The adjustments represent the repayment of existing indebtedness and
    related accrued interest and preferred dividends accrued by the Company,
    including an estimated debt retirement premium of $42,000 ($26,040 after
    related tax effect), and assumes all note holders tender their Tendered
    Notes in the Debt Tender Offers. Such premium and unamortized deferred loan
    costs of $7,450 ($4,619 after related tax effect) related to existing
    indebtedness will be written off as an extraordinary charge upon repayment
    of the existing indebtedness.
 
(6) The adjustment represents the estimated transaction fees and expenses of
    $78,000. The portion of estimated transaction fees and expenses
    attributable to the Credit Facility and the Notes offered hereby totals
    $60,891 and will be recorded as debt issuance costs and will be amortized
    over the expected life of the debt to be issued. Such estimated debt
    issuance costs include estimated fees and expenses payable to banks and
    related advisors. The remaining estimated transaction fees and expenses of
    $17,109 represent costs associated with the equity transactions.
 
      (b) The pro forma consolidated balance sheet of Centennial Cellular
Operating excludes $180,000 of gross proceeds from the Mezzanine Financing.
Centennial Cellular Operating's pro forma additional paid-in capital and
accumulated deficit were therefore not affected by a distribution of this
amount. Accumulated deficit is calculated as follows:

                  NOTES TO PRO FORMA STATEMENTS OF OPERATIONS
                            (Dollars in thousands)
 
      The pro forma financial data have been derived by the application of pro
forma adjustments to the Company's historical financial statements for the
periods noted. The Merger will be accounted for as a recapitalization which
will have no impact on the historical basis of the Company's assets and
liabilities. The pro forma financial data assumes that there are no dissenting
stockholders to the Merger.
 
      The pro forma adjustments to the Statement of Operations exclude (a) the
write-offs of $7,450 ($4,619 after related tax effect) of deferred loan costs
associated with the existing indebtedness, (b) the estimated $42,000 ($26,040
after related tax effect) of fees payable for the early retirement of existing
indebtedness, (c) $42,332 ($31,608 after related tax effect) of employee
compensation expenses relating to the exercise of the options, and (d) $2,638
($1,635 after related tax effect) deferred compensation expenses. Such amounts
represent non-recurring expenses which the Company anticipates will be
recorded in the Consolidated Statement of Operations for the period including
the Merger.
      (a) The pro forma statement of operations of Centennial Cellular
Operating include all of the same adjustments made for Centennial noted below
except interest expense related to the Subordinated Notes described in the
table under note (d).
      (b) To eliminate interest income on overnight deposits.
      (c) Represents estimated monitoring fee to be paid to affiliates of WCAS
VIII and Blackstone.
      (d) The pro forma adjustments to interest expense reflect the following:

presented because it is a widely accepted financial indicator of a company's
ability to service and/or incur indebtedness. EBITDA should not be considered
an alternative to net income as a measure of the Company's operating results or
to cash flow as a measure of liquidity. In addition, although the EBITDA
measure of performance is not recognized under generally accepted accounting
principles, it is widely used by various companies as a general measure of a
company's performance because it assists in comparing performance on a
relatively consistent

basis across companies without regard to depreciation and amortization, which
can vary significantly depending on accounting methods (particularly where
acquisitions are involved) or non-operating factors such as historical cost
bases. Because EBITDA is not calculated identically by all companies, the
presentation herein may not be strictly comparable to other similarly titled
measures of other companies.
 
      Pro forma EBITDA is calculated as follows:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
General
 
      The Company is in a highly competitive business, competing with other
providers of cellular service and PCS and providers of telephone services using
different and competing technologies. Since August 1988, the Company has
acquired twenty-nine cellular telephone markets in the United States that it
owns and manages (the "Domestic Wireless Telephone Systems"). In addition, the
Company provides a broad range of wireless and wireline services throughout
Puerto Rico (the "Puerto Rico Systems"). The Company was the first entrant into
the Puerto Rico PCS market and also provides wireless local loop services to
both business and residential customers. The Company's wholly-owned subsidiary,
Lambda Communications Inc., a competitive local exchange carrier, is the only
authorized and operating provider of local telephone service in Puerto Rico
competing with the government-owned Puerto Rico Telephone Company.
 
      The Company must continue to adapt its business to technological,
competitive and economic changes. It is dependent on its ability to increase
its number of subscribers, net of cancellations, and to achieve acceptable
revenue per subscriber levels in increasingly competitive markets. The Company
expects net losses to continue until such time as the Domestic Wireless
Telephone Systems, the Puerto Rico Systems and related investments associated
with the acquisition, construction and development of its Domestic Wireless
Telephone Systems and Puerto Rico telecommunications network plant generate
sufficient earnings to offset the costs of such activities. There can be no
assurance that profitability will be achieved in the foreseeable future.
 
      The Company has been highly leveraged, and its leverage increased
substantially as a result of the Merger. The Company has required substantial
capital to operate, construct, expand and acquire wireless telephone systems,
to build-out its recently acquired Puerto Rico telecommunications network, and
to pay debt service and preferred stock dividends. Historically, the Company
has been dependent upon borrowings, the issuance of its equity securities and
operating cash flow to provide funds for such purposes. The Company currently
expects to rely on internally generated funds and borrowings under the Credit
Facility for its capital needs. There can be no assurance that it will continue
to have access to such sources of funds.
 
      The Company earns a substantial portion of its revenue from customers of
other cellular providers who are roaming in the Company's markets. Roaming
rates per minute pursuant to reciprocal roaming arrangements have declined over
the last several years and the Company expects that such declines will continue
for the foreseeable future. While the Company benefits from lower roaming rates
when it remits to other cellular providers roaming charges incurred by the
Company's subscribers in other cellular providers' calling regions, the Company
receives less revenue per minute of use from customers roaming in its markets.
The Company believes, however, that a decline in roaming rates may be
beneficial to the Company on balance and consistent with a strategy of
increasing cellular traffic between the Company's cellular markets and
contiguous cellular markets served by other cellular operators. The Company has
implemented a strategy of aggressively pricing roaming rates to encourage other
cellular and PCS providers to include portions of the Company's service areas
within their home calling regions and to discourage wireless providers from
expanding their footprints into Centennial's service areas.
 
Six Months Ended November 30, 1998 Compared to Six Months Ended November 30,
1997
 
      Revenue for the six months ended November 30, 1998 was $164.6 million, an
increase of $53.8 million or 49% over revenue of $110.8 million for the six
months ended November 30, 1997, reflecting growth in subscriptions to wireless
telephone service, of $54.2 million partially offset by reductions in rates
charged to subscribers of $5.5 million. Secondarily, the increase reflects
increased roamer usage of $11.2 million, partially offset by lower reciprocal
roaming rates with other wireless carriers of $6.1 million. The Puerto Rico
Wireless
 
                                       63
<PAGE>
 
Telephone System accounted for $31.6 million or 59% of the total increase in
revenue. This increase reflects subscriber growth of $35.4 million, partially
offset by subscriber rate reductions of $3.8 million.
 
      Revenue from the sale of wireless telephones and accessories to
subscribers for the six months ended November 30, 1998 increased by $0.5
million to $2.9 million or 20% as compared to the six months ended November 30,
1997. The increase in revenue was due to a larger number of telephone units
sold during the current six-month period. The Puerto Rico Wireless Telephone
System accounted for $1.0 million and $0.5 million of the equipment sales for
the six months ended November 30, 1998 and 1997, respectively.
 
      Continued growth in revenue is dependent upon increased levels of
wireless subscriptions and maintenance of the current subscriber base and the
average revenue per subscriber. Wireless telephone subscribers at November 30,
1998 were approximately 384,600, an increase of 43% from the 268,600
subscribers at November 30, 1997. Increases from new activations of 207,000
were offset by subscriber cancellations of 91,000. The cancellations
experienced by the Company are primarily the result of competitive factors. The
Puerto Rico Wireless Telephone System had approximately 98,700 and 50,700
subscribers at November 30, 1998, and 1997, respectively, and, as a result,
accounted for 41% of the net increase in subscriptions.
 
      Consolidated revenue per subscriber per month, based upon an average
number of subscribers for the six months ended November 30, 1998, was $74 as
compared to $78 for the six months ended November 30, 1997. The average monthly
revenue per subscriber was approximately $69 in the domestic markets, as
compared to approximately $89 in the Company's Puerto Rico Wireless Telephone
System. The Company expects that per subscriber revenue will continue to be
impacted by competition, the expansion of its local service calling areas and
lower reciprocal per minute roaming rates with other wireless carriers.
 
      Cost of services during the six months ended November 30, 1998 was $22.1
million, an increase of $3.7 million or 20% from the six months ended November
30, 1997. The increase was primarily due to the continued growth of PCS
telephone service in Puerto Rico. Cost of services for the Puerto Rico Wireless
Telephone System was $9.6 million and $6.3 million for the six months ended
November 30, 1998 and 1997, respectively. Secondarily, the variable costs
associated with a larger revenue and subscription base and increased coverage
areas resulting from the continued expansion of the Company's network accounted
for approximately $0.4 million of the increase.
 
      Cost of equipment sold during the six months ended November 30, 1998 was
$9.5 million, an increase of $0.8 million or 10% as compared to the six months
ended November 30, 1997. Domestic costs have declined as a result of a general
decline in the wholesale prices of telephones of approximately 27%. Cost of
equipment sold (primarily accessory equipment) for the Puerto Rico Wireless
Telephone System was $1.3 million and $0.3 million for the six months ended
November 30, 1998 and 1997, respectively.
 
      Selling, general and administrative expenses rose to $51.4 million for
the six months ended November 30, 1998, an increase of $11.8 million or 30%
above the expenses of $39.7 million for the six months ended November 30, 1997.
The Company's managerial, customer service and sales staff increased
approximately 21% to accommodate the larger subscription and revenue base,
anticipated growth of its wireless telephone business and the continued growth
of telephone services in Puerto Rico. Selling, general and administrative
expenses for the Puerto Rico Wireless Telephone System were $19.6 million and
$12.5 million for the six months ended November 30, 1998 and 1997,
respectively.
 
      The Company anticipates continued increases in the cost of services and
selling, general and administrative expenses as the growth of its existing
wireless telephone business continues. In addition, the Company expects that
the continued development of its markets as well as its participation in the
Puerto Rico telecommunications business will contribute to a continued increase
in the level of expenses.

      Depreciation and amortization for the six months ended November 30, 1998
was $64.5 million, an increase of $11.8 million or 22% over the six months
ended November 30, 1997. The increase resulted from capital expenditures made
during the six months ended November 30, 1998 and during the fiscal year ended
May 31, 1998 in connection with the development and network expansion of the
Company's wireless telephone systems and the purchase of PCS phones in Puerto
Rico. Depreciation and amortization related to the Puerto Rico Wireless
Telephone System accounted for $10.5 million or 89% of the increase.
 
      As a result of the factors noted above, the operating income for the six
months ended November 30, 1998 was $17.0 million, an increase of $25.8 million
from the operating loss of $8.7 million for the six months ended November 30,
1997. The operating loss for the Puerto Rico Wireless Telephone System was $1.7
million and $11.4 million for the six months ended November 30, 1998 and 1997,
respectively.
 
      Net interest expense was $21.9 million for the six months ended November
30, 1998, an increase of $1.4 million or 7% from the six months ended November
30, 1997. The increase in interest expense reflects additional borrowings of
$31.5 million for working capital, debt service and capital expenditures
related to the buildout of the Puerto Rico Wireless Telephone System's PCS
network infrastructure and the purchase of PCS telephones. The average debt
outstanding during the six months ended November 30, 1998 was $503.4 million,
an increase of $51.9 million as compared to the average debt level of $451.6
million during the six months ended November 30, 1997. The increase in average
debt outstanding is principally related to borrowings for the Puerto Rico
Wireless Telephone System. The Company's weighted average interest rate
decreased to 9.1% for the six months ended November 30, 1998 from 9.7% for the
six months ended November 30, 1997.
 
      After income attributable to minority interests in subsidiaries for the
six months ended November 30, 1998, pretax income was $12.2 million as compared
to a pretax loss of $22.1 million for the six months ended November 30, 1997.
The income tax expense of $5.8 million for the six months ended November 30,
1998 resulted primarily from the pre-tax gain of $9.6 million the Company
recognized on the sale of its Investment Interest in the Coconino, Arizona RSA
during the six months ended November 30, 1998.
 
      The net income of $6.3 million for the six months ended November 30, 1998
represents an increase of $22.8 million from the net loss of $16.4 million for
the six months ended November 30, 1997.
 
Year Ended May 31, 1998 Compared to Year Ended May 31, 1997
 
      Revenue for the year ended May 31, 1998 was $237.5 million, an increase
of $86.5 million or 57% over revenue of $151.0 million for the year ended May
31, 1997, reflecting growth in subscriptions to, and increased usage of,
wireless telephone service, partially offset by lower reciprocal per minute
roaming rates with other cellular carriers. The Puerto Rico Systems accounted
for $48.7 million or 56% of the total increase in revenue.
 
      Revenue from the sale of wireless telephones and accessories to
subscribers for the year ended May 31, 1998 increased by $1.9 million to $4.7
million or 65% as compared to the year ended May 31, 1997. The increase in
revenue was due to a larger number of telephone units sold during the year
ended May 31, 1998. The Puerto Rico Systems accounted for $1.2 million and $0.2
million of the equipment sales for the years ended May 31, 1998 and 1997,
respectively.
 
      Continued growth in revenue is dependent upon increased levels of
wireless subscriptions and maintenance of the current subscriber base and the
average revenue per subscriber. Wireless subscribers at May 31, 1998 were
approximately 322,200, an increase of 58% from the 203,900 subscribers at May
31, 1997. Increases from new activations of 191,400 were offset by subscriber
cancellations of 73,100. The cancellations experienced by the Company are
primarily the result of competitive factors. The Puerto Rico Systems had
approximately 69,500 and 16,900 subscribers at May 31, 1998 and 1997,
respectively, and, as a result, the Puerto Rico Systems accounted for 44% of
the net increase in subscriptions.
 
                                       65
<PAGE>
 
      Consolidated revenue per subscriber per month, based upon an average
number of subscribers for the year ended May 31, 1998, was $72 as compared to
$74 for the year ended May 31, 1997. The average monthly revenue per subscriber
was approximately $68 in the domestic markets, as compared to approximately $92
in the Company's Puerto Rico Systems. The Company expects that per subscriber
revenue will be impacted by competition, the expansion of its local service
calling areas and lower reciprocal per minute roaming rates with other wireless
carriers.
 
      Cost of services during the year ended May 31, 1998 was $38.4 million an
increase of $16.2 million or 73% from the year ended May 31, 1997. The increase
was primarily due to the continued growth of PCS telephone service in Puerto
Rico. Cost of services for the Puerto Rico Systems was $14.2 million and $3.2
million for the years ended May 31, 1998 and 1997, respectively. Secondarily,
the increase was due to the variable costs associated with a larger revenue and
subscription base and increased wireless coverage areas resulting from the
continued expansion of the Company's network.
 
      Cost of equipment sold during the year ended May 31, 1998 was $16.4
million, an increase of $0.4 million or 3% as compared to the year ended May
31, 1997. The primary reason was an increase in the number of telephone units
sold and higher phone costs in the Puerto Rico Systems. These increases were
partially offset by a general decline in the wholesale prices of telephones.
Cost of equipment sold for the Puerto Rico Systems was $0.8 million and $0.6
million for the years ended May 31, 1998 and 1997, respectively.
 
      Selling, general and administrative expenses rose to $81.8 million for
the year ended May 31, 1998, an increase of $26.7 million or 48% above the
expenses of $55.1 million for the year ended May 31, 1997. The Company's
managerial, customer service and sales staff increased to accommodate the
larger subscription and revenue base, anticipated growth of its wireless
telephone business and the continued growth of telephone services in Puerto
Rico. Selling, general and administrative expenses for the Puerto Rico Systems
were $26.8 million and $10.6 million for the years ended May 31, 1998 and 1997,
respectively.
 
      The Company anticipates continued increases in the cost of services and
selling, general and administrative expenses as the growth of its existing
wireless telephone business continues. In addition, the Company expects that
the continued development of its markets as well as its participation in the
Puerto Rico telecommunications business will contribute to a continued increase
in the level of expenses.
 
      Depreciation and amortization for the year ended May 31, 1998 was $114.2
million, an increase of $30.5 million or 36% over the year ended May 31, 1997.
The increase resulted from capital expenditures made during fiscal 1998 and
1997 in connection with the development and network expansion of the Company's
wireless telephone systems. Depreciation and amortization related to the Puerto
Rico Systems accounted for $26.5 million or 87% of the increase.
 
      The operating loss for the year ended May 31, 1998 was $13.3 million, a
decrease of $12.8 million or 49% from the loss of $26.1 million for the year
ended May 31, 1997. The operating loss for the Puerto Rico Systems was $20.0
million and $14.7 million for the years ended May 31, 1998 and 1997,
respectively.
 
      Interest expense was $45.2 million for the year ended May 31, 1998, an
increase of $11.8 million or 35% from the year ended May 31, 1997. Interest
expense for the year ended May 31, 1997 was reduced by $2.8 million of
capitalized interest charges related to the acquisition cost of the Company's
Puerto Rico PCS license during the pre-operational stage of the business. Gross
interest costs for the years ended May 31, 1998 and 1997 were $45.2 million and
$36.1 million, respectively. The increase in gross interest costs reflects
additional borrowings for working capital, debt service and capital
expenditures related to the build-out of the Puerto Rico Systems' PCS network
infrastructure and the purchase of PCS telephones. The average debt outstanding
during the year ended May 31, 1998 was $470.4 million, an increase of $95.5
million as compared to the average debt level of $374.9 million during the year
ended May 31, 1997. The increase in average debt outstanding is principally
related to the $76.0 million in additional borrowings for the Puerto Rico
Systems.
 
                                       66

The Company's weighted average interest rate decreased to 9.60% for the year
ended May 31, 1998 from 9.64% for the year ended May 31, 1997.
 
      After income attributable to minority interests in subsidiaries for the
year ended May 31, 1998, a pretax loss of $45.5 million was incurred, as
compared to a pretax loss of $40.6 million for the year ended May 31, 1997. The
income tax benefit of $13.6 million for the year ended May 31, 1998 represents
a reduction of the deferred tax liability by the tax effect of the current
period losses of the Company, offset by current state and local taxes for the
period. The tax benefits are non-cash in nature.
 
      The net loss of $31.9 million for the year ended May 31, 1998 represents
a decrease of $1.3 million or 4% from the net loss of $33.3 million for the
year ended May 31, 1997. The Puerto Rico PCS business accounted for 96% of the
consolidated net loss for the year ended May 31, 1998 as compared to 52% for
1997.
 
      For the year ended May 31, 1998, earnings were less than fixed charges by
$45.4 million. Fixed charges consist of interest expense, including
amortization of debt issue costs and the portion of rents deemed representative
of the interest portion of leases. The amount by which earnings were less than
fixed charges includes non-cash charges of $114.2 million relating to
depreciation and amortization.
 
Year Ended May 31, 1997 Compared to Year Ended May 31, 1996
 
      Revenue for the year ended May 31, 1997 was $151.0 million, an increase
of $38.8 million or 35% over revenue of $112.2 million for the year ended May
31, 1996, reflecting growth in subscriptions to and increased usage of wireless
telephone service. The acquisition of one domestic wireless telephone system
accounted for approximately $4.6 million or 12% of the increase in revenue. The
Puerto Rico Systems business contributed $5.9 million or 15% of the increase in
revenue.
 
      Revenue from the sale of equipment to subscribers for the year ended May
31, 1997 increased by $0.2 million or 8% to $2.9 million as compared to the
year ended May 31, 1996. The increase in such revenue was due to a larger
number of telephone units sold during the current year offset, in part, by a
reduction in the retail prices of wireless telephones.
 
      Continued growth in revenue is dependent upon increased levels of
wireless subscriptions, maintenance of the current subscriber base, and the
average revenue per subscriber. Wireless subscribers at May 31, 1997 were
approximately 203,900, an increase of 51% from the 135,000 subscribers at May
31, 1996. Increases from new activations of 104,800 and 7,500 subscribers from
acquisitions were offset by subscriber cancellations of 43,400. The
cancellations experienced by the Company are primarily the result of
competitive factors. The Puerto Rico Systems had approximately 16,900
subscribers at May 31, 1997 and, as a result, the Puerto Rico Systems accounted
for approximately 25% off the net increase in subscriptions.
 
      Consolidated revenue per subscriber per month, based upon an average
number of subscribers, was $74 for the year ended May 31, 1997, as compared to
$75 for the year ended May 31, 1996. The average monthly revenue per subscriber
for the year ended May 31, 1997 was approximately $73 in the Domestic Wireless
Telephone Systems, as compared to approximately $113 in the Company's Puerto
Rico Systems.
 
      Cost of services during the year ended May 31, 1997 was $22.2 million, an
increase of $6.9 million or 45% from the year ended May 31, 1996. The increase
was due to the variable costs associated with a larger revenue and subscription
base and increased wireless coverage areas resulting from (i) the continued
expansion of the Company's network and acquisitions completed during the fiscal
years ended May 31, 1997 and 1996 and (ii) the commencement of wireless
telephone service in Puerto Rico. Included in cost of services during the year
ended May 31, 1997 were $1.9 million of costs associated with the start-up of
the Company's Puerto Rico Systems.
 
 
                                       67
<PAGE>
 
      Cost of equipment sold during the year ended May 31, 1997 was $16.0
million, an increase of $5.2 million or 48% as compared to the year ended May
31, 1996. The primary reason for the increase was an increase in the number of
telephone units sold, offset by a decrease in the average unit cost of
telephones sold.
 
      Selling, general and administrative expenses rose to $55.1 million for
the year ended May 31, 1997, an increase of $20.9 million or 61% above the
expenses of $34.2 million for the year ended May 31, 1996. The Company
increased its managerial, customer service and sales staff to accommodate a
larger subscription and revenue base, anticipated growth of its domestic
wireless telephone systems as well as the commencement of wireless telephone
services in Puerto Rico. Included in selling, general and administrative
expenses during the year ended May 31, 1997 were $5.1 million of costs
associated with the start-up of the Company's Puerto Rico Systems.
 
      Depreciation and amortization for the year ended May 31, 1997 was $83.7
million, an increase of $12.7 million or 18% over the year ended May 31, 1996.
The increase results from acquisitions and capital expenditures made during
fiscal 1997 and 1996 in connection with the development and network expansion
of the Company's Domestic Wireless Telephone Systems and Puerto Rico Systems.
Depreciation and amortization related to the Puerto Rico Systems was $6.3
million or 50% of the increase.
 
      The operating loss for the year ended May 31, 1997 was $26.1 million, an
increase of $6.9 million or 36% from the loss of $19.1 million for the year
ended May 31, 1996.
 
      During the year ended May 31, 1997, the Company sold certain equipment
resulting in a gain of $3.8 million. During the year ended May 31, 1996, the
Company sold its 72.2% interest in the wireless telephone system serving the
Charlottesville, VA MSA for a cash purchase price of approximately $9.9
million. The Company recognized a gain of $4.2 million as a result of the sale
(see "--Acquisitions, Exchanges, and Dispositions"). In addition, the Company
recognized a gain of $4.1 million upon the sale of marketable securities
acquired and sold during fiscal 1996.
 
      Interest expense was $33.4 million for the year ended May 31, 1997, an
increase of $5.5 million or 20% from the year ended May 31, 1996. The increase
in interest expense is the result of interest charged on additional borrowings
for the Benton Harbor, Michigan acquisition, working capital needs and the
construction and, with respect to the operation of the Puerto Rico
telecommunications network as well as a decrease in capitalized interest
charges related to the pre-operational stage of the Company's Puerto Rico PCS
business. Capitalized interest for the year ended May 31, 1997 was $2.8
million, a decrease from the capitalized interest of $5.2 million for the year
ended May 31, 1996. Gross interest costs for the year ended May 31, 1997 and
May 31, 1996 were $36.1 million and $33.1 million, respectively. The average
debt outstanding during the year ended May 31, 1997 was $374.9 million, an
increase of $24.9 million as compared to the average debt level of $350.0
million during the year ended May 31, 1996. The Company's weighted average
interest rate increased to 9.64% for the year ended May 31, 1997 from 9.54% for
the year ended May 31, 1996.
 
      After income attributable to minority interests in subsidiaries for the
year ended May 31, 1997, a pretax loss of $40.6 million was incurred, as
compared to a pretax loss of $28.2 million for the year ended May 31, 1996. The
income tax benefit of $7.3 million for the year ended May 31, 1997 represents a
reduction of the deferred tax liability by the tax effect of the current period
losses of the Company, offset by current state and local taxes for the period.
The tax benefits are non-cash in nature.
 
      The net loss of $33.3 million for the year ended May 31, 1997 represents
an increase of $16.7 million or 100% from the net loss of $16.6 million for the
year ended May 31, 1996. The Puerto Rico PCS business accounted for 52% of the
consolidated net loss for the year ended May 31, 1997 as compared to 6% for
1996.

(1) EBITDA is defined, for any period, as earnings before income from Minority
    Cellular Investment Interests, allocations to minority interests in
    consolidated subsidiaries, interest expense, interest income, income taxes,
    depreciation and amortization, and gain on sale of assets. EBITDA is
    presented because it is a widely accepted financial indicator of a
    company's ability to service and/or incur indebtedness. EBITDA should not
    be considered an alternative to net income as a measure of the Company's
    operating results or to cash flow as a measure of liquidity. In addition,
    although the EBITDA measure of performance is not recognized under
    generally accepted accounting principles, it is widely used by various
    companies as a general measure of a company's performance because it
    assists in comparing performance on a relatively consistent basis across
    companies without regard to depreciation and amortization, which can vary
    significantly depending on accounting methods (particularly where
    acquisitions are involved) or non-operating factors such as historical cost
    bases. Because EBITDA is not calculated identically by all companies, the
    presentation herein may not be strictly comparable to other similarly
    titled measures of other companies.
 
Liquidity and Capital Resources
 
Historical
 
     The Company has historically relied primarily on bank debt, the issuance
of debt securities, the issuance of Common Shares and the incurrence of debt by
its subsidiaries in order to fund its working capital requirements,
acquisitions, capital expenditures and debt service. For the six months ended
November 30, 1998, earnings exceeded fixed charges by $12.2 million. For the
year ended May 31, 1998, earnings were less than fixed charges by $45.4
million. Fixed charges consist of interest expense, including amortization of
debt issue costs and the portion of rents deemed representative of the interest
portion of leases. The amount by which earnings exceeded fixed charges reflects
non-cash charges of $64.5 million and $114.2 million relating to depreciation
and amortization during the six months ended November 30, 1998 and year ended
May 31, 1998, respectively.

      During the six months ended November 30, 1998, the Company made capital
expenditures of $48.8 million, primarily to continue the construction of its
Puerto Rico Systems and its Domestic Wireless Telephone Systems to expand the
coverage areas of existing properties and to upgrade its cell sites and call
switching equipment. Capital expenditures for the Company's Puerto Rico Systems
were $30.6 million for the six months ended November 30, 1998, representing 63%
of the Company's total capital expenditures. The Puerto Rico Systems capital
expenditures included $14.7 million to continue the build-out of the Company's
PCS network infrastructure and $16.0 million to purchase telephone units which
remain the property of the Company while in use by subscribers. The Company's
future commitments for property and equipment include the addition of cell
sites to expand coverage and enhancements to the existing infrastructure of its
wireless telephone systems. During fiscal 1999, the Company anticipates capital
expenditures in the Domestic Wireless Telephone Systems of approximately $40.0
million. The Company currently estimates that the cost to continue the build-
out of its Puerto Rico network infrastructure through fiscal 1999 will be
approximately $50.0 million. This increase is an acceleration of expenditures
that would otherwise take place in future years and is related to the growth
the Company has experienced in its Puerto Rico Systems. It is anticipated that
the Company will seek various sources of external financing including, but not
limited to, bank financing, joint ventures, partnerships and placement of debt
or equity securities of the Company.
 
      Centennial Puerto Rico Wireless Corporation, a wholly owned subsidiary of
the Company ("CPRW"), has a four-year, $180.0 million revolving credit facility
(as amended, the "Old Puerto Rico Credit Facility"). As of November 30, 1998,
the Old Puerto Rico Credit Facility had $157.0 million outstanding. The
interest rate payable by CPRW on borrowings under the Old Puerto Rico Credit
Facility is based, at the election of CPRW, on (a) the Base Rate, as defined,
plus a margin of 1.50% or (b) the Eurodollar Base Rate, as defined, plus a
margin of 2.50%, adjusted for the maintenance of certain specified ratios, as
applicable. All indebtedness under the Old Puerto Rico Credit Facility was
repaid at the time of the Merger.
 
      As of November 30, 1998, no amounts were outstanding under the Company's
$75 million domestic revolving credit facility (the "Old Domestic Credit
Facility"). The interest rate payable on the Old Domestic Credit Facility is
based, at the election of the Company, on (a) the Base Rate, as defined, plus a
margin of 2% or (b) the Eurodollar Base Rate, as defined, plus a margin of 3%.
All indebtedness under the Old Rural Cellular Credit Facility was repaid at the
time of the Merger.
 
      The Company also had two outstanding public issuances of debt securities,
its $250 million 8 7/8% Senior Notes due 2001 (the "2001 Notes") and its $100
million 10 1/8% Senior Notes due 2005 (the "2005 Notes"). In connection with
the Merger, Centennial consummated the Debt Tender Offers to acquire
substantially all of its outstanding 2001 Notes and 2005 Notes. As of the
expiration date of the Debt Tender Offers, approximately 99% of the Company's
public debt was tendered to the Company. The Company completed the Debt Tender
Offers concurrently with the effective time of the Merger.
 
      As of November 30, 1998, the Company had $272.2 million of property,
plant and equipment (net) placed in service. During the six months ended
November 30, 1998 and the year ended May 31, 1998, the Company made capital
expenditures of $48.8 million and $129.3 million, respectively, primarily to
continue the construction of its Puerto Rico Systems and its Domestic Wireless
Telephone Systems, to expand the coverage areas of existing properties and to
upgrade its cell sites and call switching equipment. Capital expenditures for
the Company's Puerto Rico Systems were $90.3 million for the year ended May 31,
1998, representing 70% of the Company's total capital expenditures. The Puerto
Rico Systems capital expenditures included $57.1 million to continue the build-
out of the Company's PCS network infrastructure and $33.2 million to purchase
telephone units which remain the property of the Company while in use by
subscribers. The Company's future commitments for property and equipment
include the addition of cell sites to expand coverage and enhancements to the
existing infrastructure of its wireless telephone systems. During fiscal 1999,
the Company anticipates capital expenditures in the Domestic Wireless Telephone
Systems of approximately $40 million.

      In order to meet its obligations with respect to its operating needs,
capital expenditures, debt service and preferred stock obligations, it is
important that the Company continue to improve operating cash flow. In order to
do so, the Company's revenue must increase at a faster rate than operating
expenses. Increases in revenue will be dependent upon continuing growth in the
number of subscribers and maximizing revenue per subscriber. The Company has
continued the development of its managerial, administrative and marketing
functions, and is continuing the construction of wireless systems in its
existing and recently acquired markets in order to achieve these objectives.
There is no assurance that growth in subscribers or revenue will occur.
 
      In addition, the Company's participation in the Puerto Rico
telecommunications business has been, and is expected to continue to be,
capital intensive. Further, due to the start-up nature of the Puerto Rico
telecommunications operations, the Company expects that it will require
additional cash investment to fund its operations over the next several years.
The Puerto Rico telecommunications operations has been, and is expected to
continue to be, highly competitive with the two existing wireless telephone
providers, as well as the other Puerto Rico telecommunications license holders.
There is no assurance that the Puerto Rico telecommunications operations will
generate cash flow or reach profitability. Even if the Company's operating cash
flow increases, it is anticipated that cash generated from the Company's
wireless telephone systems will not be sufficient in the next several years to
cover interest, the preferred stock dividends that may be declared and made
payable and required capital expenditures.
 
      The Company anticipates that shortfalls in cash flow may be made up
either through debt and equity issuances or additional financing arrangements
that may be entered into by the Company. It is anticipated that the Company's
future funding needs will be met by the refinancing arrangements that are
expected to be made in connection with the Merger, although there is no
assurance that this refinancing will be obtained. Based upon current market
conditions and its current capital structure, the Company believes that cash
flows from operations and funds from available credit facilities will be
sufficient to enable the Company to meet required cash commitments for the
foreseeable future.
 
      The Company has filed a shelf registration statement with the Commission
for up to 8,000,000 shares of its Class A Common Stock that may be offered from
time to time in connection with acquisitions. The registration statement was
declared effective by the Commission on July 14, 1994. As of September 23,
1998, 4,239,231 shares remain available for issuance under this shelf
registration.
 
      The Company has filed a shelf registration statement with the Commission
for the issuance of $500 million of the Company's debt securities which was
declared effective by the Commission on April 6, 1995. The debt securities may
be issued from time to time in series on terms to be specified in one or more
prospectus supplements at the time of the offering. If so specified with
respect to any particular series, the debt securities may be convertible into
shares of the Company's Class A Common Stock. As of September 23, 1998, $400
million remained available for issuance under this shelf registration.
 
After the Merger
 
      Following the consummation of the Merger, Centennial Cellular Operating
has, on a consolidated basis, long-term indebtedness aggregating approximately
$1.31 billion. In addition, Centennial (without its subsidiaries) has $180
million (face amount) of long-term indebtedness. Substantially all of the
proceeds of such indebtedness were used to pay the consideration to
Centennial's stockholders in the Merger, repay Centennial's indebtedness
(including the purchase of Tendered Notes in the Debt Tender Offers), pay the
related fees and expenses and purchase the Pledged Securities. See "Use of
Proceeds."
 
      As a result of the Merger, the Obligors have significant cash
requirements for debt service. To meet their liquidity needs, the Obligors
currently expect to rely on internally generated funds, borrowings under the
revolving portion of the Credit Facility and, for the first three scheduled
interest payments of the Notes, the
 
                                       71
<PAGE>
 
Pledged Securities. On a pro forma basis, at November 30, 1998, Centennial
Cellular Operating and its subsidiaries would have had $114.0 million available
under the revolving portion of the Credit Facility.
 
      At the effective time of the Merger, Centennial Cellular Operating
entered into the Credit Facility. A portion of the Credit Facility was also
borrowed by Centennial de Puerto Rico. The Credit Facility provides term loans
in an aggregate principal amount of $900 million and revolving loans in an
aggregate principal amount of up to $150 million. The term loans consist of
four tranches and will amortize over eight years for each of tranche A term
loans and tranche A Puerto Rico term loans, eight and one-half years for
tranche B term loans and nine years for tranche C term loans. The revolving
loans will be reduced quarterly beginning in the fourth year and will mature
after eight years. Borrowings are subject to mandatory prepayment and reduction
in an amount equal to the net proceeds of asset dispositions, 75% of excess
cash flow reduced to 50% with respect to any fiscal year if the Total Leverage
Ratio (defined as the ratio of total debt to operating cash flow) is less than
6.0 to 1.0, the net proceeds of the issuance of debt or any sale and leaseback
and 50% of the net proceeds of any issuance of equity securities. Centennial
and each of Centennial Cellular Operating's direct and indirect existing and
future subsidiaries (other than foreign subsidiaries) have guaranteed
Centennial Cellular Operating's obligations under the Credit Facility.
Centennial Cellular Operating and Centennial de Puerto Rico's direct and
indirect existing and future subsidiaries have guaranteed Centennial de Puerto
Rico's obligations under the Credit Facility. The obligations of Centennial
Cellular Operating under the Credit Facility are secured by substantially all
of the assets of Centennial and each of its subsidiaries (other than foreign
subsidiaries), including the capital stock of such subsidiaries. The
obligations of Centennial de Puerto Rico under the Credit Facility are secured
by substantially all of the assets of Centennial de Puerto Rico and each of its
subsidiaries, including the capital stock of such subsidiaries. See
"Description of Certain Indebtedness."
 
      WCAS Capital Partners III, L.P. provided, at the effective time of the
Merger, Mezzanine Financing to Centennial in the original principal amount of
$180 million. The note will bear cash interest at a rate of 10% or pay-in-kind
interest at a rate of 13%. Centennial Cellular Operating is restricted from
making cash payments to Centennial to service the debt under certain
circumstances under the Notes and the Credit Facility. The note is prepayable
at Centennial's option and must be prepaid in the event of a Change of Control,
in each case subject to compliance with the Company's other debt instruments.
See "Description of Certain Indebtedness--Subordinated Debt."
 
      The Obligors issued $370 million of the Notes (including $57.5 million to
fund the first three interest payments). See "Description of the New Notes."
 
      Centennial plans to continue to expand its marketing efforts which will
include, but are not limited to, an increase in funds for advertising, cellular
telephone inventory purchases and other expenditures relating to subscriber
growth. For the years ending May 31, 1999 and 2000, Centennial anticipates that
it will spend approximately $40 million and $35 million, respectively, in
capital expenditures for its domestic operations. The Company currently
estimates that the capital expenditures to continue the build-out of its Puerto
Rico network infrastructure and expansion of its business operations through
fiscal 1999 will be approximately $50 million. However, actual capital
requirements may change. The ability of the Obligors to meet their debt service
obligations and reduce their total debt will be dependent on the future
performance of the Obligors, which in turn, will be subject to general economic
conditions and to financial, business and other factors, including the factors
described under "Risk Factors" and other factors beyond the Obligors' control.
 
      The Obligors believe that based on the current level of operations and
anticipated internal growth, cash flow from operations, together with other
available sources of funds, including borrowings under the revolving portion of
the Credit Facility, will be adequate to make required payments of principal
and interest on the Obligors' indebtedness and to fund anticipated capital
expenditures and working capital requirements for the foreseeable future. A
portion of the Obligors' debt bears interest at floating rates; therefore,
their financial condition is and will continue to be affected by changes in
prevailing interest rates.

Acquisitions, Exchanges and Dispositions
 
      The Company's primary acquisition strategy is to acquire controlling
ownership interests in wireless systems serving markets contiguous or proximate
to its current markets. This clustering strategy enables it to achieve
operating and cost efficiencies as well as joint advertising and marketing
benefits. Clustering also allows the Company to offer its subscribers more
areas of uninterrupted service as they travel through an area or state. In
addition to expanding its existing clusters, the Company may also seek to
acquire interests in wireless systems in other geographic areas. The Company
may also pursue other communications businesses related to its wireless
telephone and other mobile service operations, as well as other communications
businesses it determines to be desirable. The consideration for such
acquisitions may consist of shares of stock, cash, assumption of liabilities or
a combination thereof.
 
      On November 1, 1998, the Company exercised its right to acquire the
minority interests held by Century in the Cass and Jackson, Michigan systems
for the prices paid by Century for such minority interests in the acquisition
of such systems ($2.0 million and $1.0 million, respectively).
 
      On June 8, 1998, the Company disposed of its investment interest in
Arizona RSA #2, representing approximately 43,500 Net Pops, for $13.5 million
in cash. During the first quarter of fiscal 1999, the Company recorded a pre-
tax gain of approximately $9.5 million in relation to the sale of this
Investment Interest.
 
      On September 12, 1996, the Company acquired 100% of the ownership
interests in the partnership owning the wireless telephone system serving the
Benton Harbor, Michigan MSA for approximately $35.0 million in cash. The Benton
Harbor market represents approximately 161,400 Net Pops.
 
      On October 31, 1995, the Company acquired (i) a 94.3% interest in the
wireless telephone system serving the Lafayette, Louisiana MSA, representing
approximately 205,700 Net Pops, in exchange for the Company's wireless
telephone system serving the Jonesboro, Arkansas RSA (comprising approximately
205,000 Net Pops), the license rights and assets located in and covering the
Desoto and Red River Parishes of Louisiana RSA #3 (comprising approximately
34,700 Net Pops), the license rights and assets located in and covering a
section of Morehouse Parish of Louisiana RSA #2 (comprising approximately
24,100 Net Pops) and a cash payment by the Company of approximately $5.6
million, subject to adjustment, and (ii) an additional 14.3% minority interest
in the Elkhart, Indiana MSA, a market in which the Company now has a 91.4%
interest and an additional 12.7% equity investment interest in the Lake
Charles, Louisiana MSA, a market in which the Company now has a 25.1% interest,
for a cash payment of approximately $3.0 million.
 
      On June 30, 1995, the Company acquired the wireless telephone systems
serving (a) Newtown, LaPorte, Starke, Pulaski, Jasper and White, Indiana, (b)
Kosciusko, Noble, Steuben and Lagrange, Indiana, (c) Williams, Defiance, Henry
and Paulding, Ohio and (d) Copiah, Simpson, Lawrence, Jefferson Davis, Walthall
and Marion, Mississippi, representing an aggregate of approximately 608,100 Net
Pops. The above-described systems were acquired by the Company in exchange for
the Company's wireless telephone systems serving the Roanoke, Virginia MSA, the
Lynchburg, Virginia MSA, North Carolina RSA #3 and Iowa RSA #5, representing an
aggregate of approximately 644,000 Net Pops. Simultaneously with the
consummation of the transaction described above, the Company sold its 72.2%
interest in the wireless telephone system serving the Charlottesville, Virginia
MSA, representing an aggregate of approximately 94,700 Net Pops, for a cash
purchase price of approximately $9.9 million, subject to adjustment. The
Company recognized a gain of approximately $4.2 million as a result of the
sale.
 
      During the year ended May 31, 1998, the Company directly purchased
1,270,200 Common Shares in the open market for an aggregate purchase price of
$23.5 million pursuant to previous authorizations by the Company's Board of
Directors. These shares have been accounted for as treasury shares. Subsequent
to May 31, 1998, the Company has not directly purchased any additional Common
Shares in the open market. As of July 28, 1998, the Company is authorized to
directly purchase 2,729,800 additional shares of its Class A
 
                                       73
<PAGE>
 
Common Stock in the open market after giving effect to the shares purchased to
date. Additionally, through a recently terminated agreement, the Company
purchased 273,200 shares of its Class A Common Stock for approximately $5.4
million.
 
      During the six months ended November 30, 1997, the Company directly
purchased 1,181,200 shares of its Class A Common Stock in the open market for
an aggregate purchase price of $21.7 million pursuant to previous
authorizations by the Company's Board of Directors. These shares were accounted
for as treasury shares. During the six months ended November 30, 1998, the
Company did not directly purchase any additional shares of its Class A Common
Stock in the open market.
 
      The Company leases certain space for equipment in Puerto Rico from
Century-ML Cable Corp. ("Century-ML"), a cable television operator which is 50%
owned by Century, pursuant to a 25-year lease entered into in 1997 when Century
was an affiliate of the Company. Further, the Company leases and shares
capacity on the fiber optic cable television facility and network of Century-ML
for the purpose of operating as a competitive access provider. The Company
shares in the cost of construction, operation and maintenance of the Century-ML
fiber network on a pro rata basis based on the percentage of the number of
fibers of the network used by or reserved for the Company. During fiscal 1997,
the Company recorded a deferred asset and a related payable to an affiliate in
its consolidated balance sheet in the amount of $6.0 million to reflect certain
costs incurred by the Company to secure the use of the fiber optic network as
required by the Facilities Agreement with Century-ML dated January 2, 1995.
This amount, which was paid by the Company during fiscal 1998, represents the
Company's share of the costs of constructing Century-ML's fiber optic network.
 
Recent Developments
 
      In September 1998, the Commonwealth of Puerto Rico sustained damage as a
result of the effects of Hurricane Georges. The Company has evaluated the
extent of damage to its Puerto Rico network infrastructure and the impact the
hurricane has had on the Company's Puerto Rico service revenue during the three
months ended November 30, 1998. After consideration of expected insurance
recoveries, the Company believes it will not incur significant losses as a
result of the effects of the damage caused by Hurricane Georges. During the
three months ended November 30, 1998, the Company recorded approximately $1.6
million of insurance recoveries related to subscriber refunds within revenue.
 
Year 2000
 
      During fiscal 1998, the Company began a review of its computer systems
and related software to identify systems and software that might malfunction
due to a misidentification of the Year 2000. A committee consisting of members
of senior management from various disciplines within the Company has been
formed and is meeting regularly to discuss the steps that must be taken to deal
with any potential Year 2000 issues. The Company is utilizing both internal and
external resources to identify, correct or reprogram and test systems for Year
2000 readiness.
 
      Most of the Company's customer-related computer systems and data bases,
including its billing systems, are managed by third parties under contractual
arrangements. The Company has requested those third parties to advise the
Company as to whether they anticipate difficulties in addressing Year 2000
problems and, if so, the nature of such difficulties. The Company is also
working with others in the industry using the same or similar systems to
determine the appropriate steps necessary to address the anticipated
difficulties.
 
      The Company is currently undertaking an inventory of all local equipment
used in the transmission and reception of all signals to identify items that
need to be upgraded or replaced. The Company is also monitoring industry-wide
efforts with respect to signal delivery to its distribution plant and is
working with others in the industry to address potential solutions.
 
                                       74
<PAGE>
 
      Management of the Company has not finally determined the cost associated
with its Year 2000 readiness efforts and the related potential impact on the
Company's results of operations. Amounts expended to date have not been
material. There can be no assurance that the systems of other companies on
which the Company relies will be converted in time or that any such failure to
convert by another company will not have a material adverse effect on the
Company's business, financial condition or results of operations.
 
      After evaluating its internal compliance efforts as well as the
compliance of third parties as described above by the end of calendar year
1998, the Company will develop during 1999 appropriate contingency plans to
address situations in which various systems of the Company, or of third parties
with which the Company does business, are not Year 2000-compliant.
 
Certain Information Provided to WCAS VIII
 
      Prior to the execution of the Merger Agreement, in connection with WCAS
VIII's review of the Company, the Company provided representatives of WCAS VIII
information concerning projected revenue and expenses of the Company which was
prepared in June 1998. WCAS VIII has informed the Company that, in its
judgment, it does not expect the projected results to be achieved and,
accordingly, did not rely on such projections in negotiating the Merger
Agreement or the amount of the Cash Merger Consideration.

      The foregoing Company projections were based on the following
assumptions:
 
      (1) Subscribers are assumed to grow at a compound annual growth rate of
14% through 2004 for domestic operations and wireless subscribers are assumed
to grow at a compounded annual growth rate of 28% through 2004 for Puerto Rico
operations.
 
      (2) Service revenues per subscriber are assumed to decrease 5% in year
2000, 2.5% in 2001 and 1.5% in 2002, and remain flat thereafter for domestic
operations and service revenues per subscriber are assumed to decrease over the
next five years for Puerto Rico operations.

      The Company does not as a matter of course make public any projections as
to future performance or earnings, and the projections set forth above are
included in this Prospectus only because the information was made available to
representatives of WCAS VIII by the Company and were required to be included in
the Company's registration statement on Form S-4 filed with the Commission
relating to Centennial's stockholder information statement relating to the
Merger. The management of the Company has prepared the forecasted financial
information set forth above to present the five-year projections for the
Company. These forecasts were prepared in June 1998 and have not been updated.
The prospective financial information was not prepared with a view toward
public disclosure or with a view towards complying with the guidelines
established by the American Institute of Certified Public Accountants with
respect to prospective financial information, but, in the view of the Company's
management, were prepared on a reasonable basis, reflect the Company's
estimates and judgments at the time of preparation and presented, to the best
of management's knowledge and belief at the time of preparation, the expected
course of action and the expected future financial performance of the Company.
However, this information is not fact and should not be relied upon as
necessarily indicative of future results, and potential purchasers of the Notes
are cautioned not to place any reliance on the forecasted financial
information. Neither the Company's independent auditors, nor any other
independent accountants or financial advisors, nor the Initial Purchasers have
compiled, examined, or performed any procedures with respect to the prospective
financial information contained herein, nor have they expressed any opinion or
any form of assurance on such information or its achievability, and assume no
responsibility for, and disclaim any association with, the prospective
financial information.
 
      The Company has also informed WCAS VIII that its internal financial
forecasts (upon which the projected financial performance provided to WCAS VIII
was based in part) are, in general, prepared solely for internal use and
capital budgeting and other management decision-making purposes and are
subjective in many respects and thus susceptible to various interpretations and
periodic revision based on actual experience and business developments.
Projected information of this type is based on estimates and assumptions that
are inherently subject to significant economic and competitive uncertainties
and contingencies, all of which are difficult to predict and many of which are
beyond the control of the Company, WCAS VIII or Acquisition or their respective
financial advisors, including the Initial Purchasers. Many of the assumptions
upon which the foregoing projected financial performance was based, none of
which was approved by WCAS VIII, Acquisition or the Initial Purchasers, are
dependent upon economic forecasting (both general and specific to the Company's
businesses), which is inherently uncertain and subjective. ACCORDINGLY, THERE
CAN BE NO ASSURANCE THAT FORECASTED RESULTS ARE INDICATIVE OF THE FUTURE
PERFORMANCE OF THE COMPANY OR THAT ACTUAL RESULTS WILL NOT BE MATERIALLY HIGHER
OR LOWER THAN THOSE FORECASTED. INCLUSION OF THE PROSPECTIVE FINANCIAL
INFORMATION IN THIS PROSPECTUS SHOULD NOT BE REGARDED AS A REPRESENTATION BY
ANY PERSON THAT THE FORECASTED RESULTS WILL BE ACHIEVED. None of WCAS VIII,
Acquisition, the Company or their respective financial advisors, including the
Initial Purchasers, assumes any responsibility for the ultimate outcome of any
of such projections. Inclusion of the foregoing projections should not be
regarded as an indication that WCAS VIII, Acquisition, the Company or any other
person who received such information considers it an accurate prediction of
future events.
 
      The Company does not generally publish its business plans and strategies
or make external forecasts of its anticipated financial position or results of
operations. Accordingly, none of WCAS VIII, Acquisition or the Company, or
their respective financial advisors (including the Initial Purchasers), or any
other party, intends to publicly update or otherwise publicly revise the
projections set forth above to reflect circumstances existing since their
preparation or to reflect the occurrence of unanticipated events, even in the
event that any or all of the underlying assumptions are shown to be in error.
Furthermore, the Company does not intend to update or revise the prospective
financial information to reflect changes in general economic or industry
conditions.

     .  That the indenture and the credit facility impose significant
        operating and financial restrictions on Centennial Cellular
        Operating,
 
     .  That Centennial Cellular Operating has pledged the capital stock

     .  That the right of the trustee under the indenture and a Pledge and
        Escrow Agreement to obtain payment on the notes upon the
        occurrence of an event of default may be significantly impaired by
        applicable bankruptcy law,

     .  Risks associated with new management and any future changes in
        management,
 
     .  That certain equity investors control Centennial and its
        subsidiaries and have the power to elect directors and take other
        corporate actions,
 
     .  That we have limited ability to direct the operations of the
        systems in which we hold minority cellular investment interests as

                           Centennial Cellular Corp.
 
      Our company is one of the largest independent wireless telecommunications
service providers in the United States and Puerto Rico with approximately 10.8
million Net Pops and 384,600 subscribers as of November 30, 1998. Centennial
Rural Cellular serves 5.8 million Net Pops and its service area covers
approximately 81,645 square miles. Our subsidiary, Centennial de Puerto Rico,
is a fully integrated provider of communications services in Puerto Rico. These
operations utilize a PCS license that covers 3.8 million Pops in Puerto Rico
and the U.S. Virgin Islands and a CLEC license to operate in Puerto Rico. In
addition, we own minority shares, representing approximately 1.2 million Net
Pops, in certain Minority Cellular Investment Interests.
 
      The table below shows certain data for each of our two principal business
segments.

</TABLE>
 
      For the year ended May 31, 1998, our company earned revenue of $237.5
million, representing a CAGR of 45% over the previous two fiscal years. EBITDA
for the year ended May 31, 1998 was $99.2 million, representing a CAGR of 44%
over the previous two fiscal years.
 
      The success of our company's operating and financial performance has been
driven by the quality and experience of its management and employees. We expect
to continue to benefit from the experienced members of operating management who
are expected to remain at Centennial Rural Cellular following the Merger. This
management team built the Company through internal growth and acquisitions from
approximately 1.7 million Net Pops in 1988 to approximately 10.8 million Net
Pops (including those in Puerto Rico and Minority Cellular Investment
Interests) as of November 30, 1998. The addition of Michael Small, formerly the
Chief Financial Officer of 360(degrees) Communications Company (now a
subsidiary of ALLTEL Corporation), as our Chief Executive Officer following the
Merger complements the existing management team. Rudy J. Graf, who has been the
Chief Operating Officer of the Company since 1991, will continue to manage the
day-to-day operations of the Company
 
Centennial's Rural Cellular Systems
 
      Centennial's domestic consolidated systems are among the leading
independent providers of rural non-wireline cellular telecommunications
services. We believe our rural and small-city cellular systems provide strong
growth opportunities due to lower penetration rates and higher subscriber
growth rates. We focus on underdeveloped rural and small-city cellular areas
that have a significant number of potential customers for wireless
communications because we believe these areas offer:
 
     .  Potential Penetration Growth. We believe these areas are in the
        early stages of their growth cycles and offer significant
        opportunities for increases in penetration and cellular usage;
 
                                       79
<PAGE>
 
     .  Insulation from Potential Competition. These regions are currently
        subject to less competition from other wireless providers (such as
        PCS) as compared to larger MSAs, and the population density of
        these regions suggests that the build-out of a PCS network may not
        be economically attractive to competitors at present; and
 
     .  Above-Average Revenue per Subscriber. Our domestic markets, which
        are strategically located between larger metropolitan areas, tend
        to exhibit long commute times and well-traveled roadways that have
        the potential to generate high levels of cellular MOUs and roaming
        revenues.
 
      The Company's domestic cellular interests consist primarily of three
operating clusters:
 
     .  Michiana Cluster contains approximately 3.4 million Net Pops in
        Michigan, Ohio and Indiana, covering portions of three major
        interstate highways that connect Chicago, Detroit and
        Indianapolis.
 
     .  East Texas/Louisiana Cluster contains approximately 2.1 million
        Net Pops, covering portions of interstate highway I-10, as well as
        sections of Texas, Louisiana and Mississippi adjacent to Houston,
        New Orleans, Shreveport and Baton Rouge.
 
     .  Southwestern Cluster contains approximately 296,000 Net Pops,
        covering the Yuma, Arizona and El Centro, California markets and
        is bordered by Los Angeles to the northwest, San Diego to the
        west, Phoenix to the east and Mexicali, Mexico to the south.
 
      Our domestic operations have achieved significant increases in revenue,
EBITDA and number of subscribers since 1988. For the year ended May 31, 1998,
the Company's domestic operations earned revenue of $182.9 million,
representing a CAGR of 28% over the previous two fiscal years. EBITDA from
domestic operations for the year ended May 31, 1998 was $86.7 million,
representing a CAGR of 34% over the previous two fiscal years. As of May 31,
1998, the Company's domestic operations had approximately 252,700 subscribers,
representing a CAGR of 37% over the number of subscribers in the previous two
fiscal years.
 
Centennial's Puerto Rico Systems
 
      Our Puerto Rico business, which is conducted through Centennial de
Puerto Rico, is a facilities-based ICP of a broad range of wireless and
wireline services in the Commonwealth of Puerto Rico (an area covering
approximately 3.8 million Pops). It is (i) the only provider of PCS services
in the Puerto Rico market, (ii) a provider of facilities-based wireless local
loop services to both business and residential customers, and (iii) a provider
of local, long distance and enhanced data services through its subsidiary,
Lambda CLEC, which competes with the incumbent PRTC. We believe that Puerto
Rico represents an attractive market for communications services due to unmet
demand for wireless and local phone service, high population density in the
island's metropolitan areas, a growing economy and a stable business
environment.
 
      Centennial de Puerto Rico offers wireless and wireline services using a
shared Lucent Technologies 5 ESS switch and its sophisticated fiber optic
network, which contains over 292 route miles of fiber throughout the island of
Puerto Rico. The digital PCS network allows for coverage in most areas of
Puerto Rico using its established base of 120 cell sites and CDMA technology
to transmit its calls.
 
     .  Wireless Services. Centennial de Puerto Rico offers both PCS and
        wireless local loop service to its customers. Our PCS business
        currently covers approximately 85% of the total Pops on the island
        of Puerto Rico and targets high volume users. We began offering
        PCS in December 1996 and as of November 30, 1998 had approximately
        98,700 subscribers, an increase of 95% over our approximately
        50,700 subscribers at November 30, 1997. Our ARPU per PCS customer
        was approximately $89 during the three months ended November 30,
        1998, compared to approximately $46 for the average U.S. wireless
        customer for the six months ended June 30,
 
                                      80
<PAGE>
 
        1998, according to data from the CTIA. Centennial de Puerto Rico
        began offering wireless local loop service to business and
        residential customers in August 1997. Our ARPU per wireless local
        loop customer was $87 during the three months ended November 30,
        1998. This service uses our fully digital CDMA network in Puerto
        Rico and had over 14,200 subscribers as of November 30, 1998.
 
     .  Wireline Services. Lambda CLEC provides local, long distance and
        enhanced data services (including Internet-related services) to
        business and government customers over our high bandwidth, fiber
        optic network. We believe that our targeted CLEC customers have
        sophisticated communications service requirements, including the
        need for a reliable network providing data access and private line
        services and high quality customer service. Lambda CLEC has grown
        rapidly since its inception in September 1997, primarily due to
        its ability to offer a broad range of products as well as
        responsive and reliable service in an underserved market. Lambda
        CLEC provided approximately 41.7 million MOUs to its customers in
        November 1998, an increase of 87% over the MOUs provided in May
        1998.
 
      Since operations commenced in December 1996, Centennial de Puerto Rico
has achieved significant growth in subscribers, revenue and EBITDA, which we
attribute to our premium service capabilities, experienced local management
team and limited competition in the region. Revenue for the fiscal year ended
May 31, 1998 was $54.6 million, compared to $5.9 million for the year ended
May 31, 1997. EBITDA for the fiscal year ended May 31, 1998 was $12.5 million,
compared to an EBITDA deficit of $(8.4) million for the prior period. Revenue
for the six months ended November 30, 1998 was $51.8 million. EBITDA for the
six months ended November 30, 1998 was $21.3 million or $42.6 million on an
annualized basis.

Rural Cellular Markets and Systems
 
      The Company has focused on acquiring controlling ownership interests in
wireless telephone systems serving markets contiguous or proximate to its
current markets. The Company's strategy of clustering its wireless telephone
operations enables it to achieve operating and cost efficiencies, as well as
joint advertising and marketing benefits. Clustering also allows the Company to
offer its subscribers more areas of uninterrupted service as they travel
through an area or state. In addition to expanding its existing clusters, the
Company may seek to acquire interests in wireless telephone systems in other
geographic areas.
 
      The table below sets forth certain information about Centennial's
domestic systems as of February 28, 1999.

Centennial's Minority Cellular Investment Interests
 
      The Company holds Minority Cellular Investment Interests in six
independent cellular partnerships which own and operate cellular telephone
systems in the United States. The partnerships operate primarily in RSAs or
MSAs that include or are contiguous to major cities or that contain expressway
corridors linking metropolitan areas. Centennial acquired the Minority Cellular
Investment Interests in August 1991 in connection with a merger with Citizens
Cellular Company, which was a wholly owned subsidiary of Citizens Utilities
Company ("Citizens"). Citizens had acquired these interests as a result of
agreements among various companies providing local exchange telephone service
in markets in which Citizens also provided such service. The Company is
considering various alternatives with respect to the Minority Cellular
Investment Interests, including either selling such interests to its partners
in each respective partnership or, in some case, acquiring interests from its
partners in order to control the operations itself.

      At May 31, 1998, the Company's pro rata shares of subscribers relating to
the Minority Cellular Investment Interests was approximately 122,000.
 
Products and Services
 
      The Company's principal source of revenue in its domestic markets is
providing service to wireless telephone subscribers. The services available to
wireless telephone subscribers are similar to those provided by conventional
landline telephone systems, including custom calling features such as voice
mail, call forwarding, call waiting and conference calling.
 
      The Company is responsible for the quality, pricing and packaging of its
wireless service for its cellular systems. The Company offers several pricing
plans and customers are able to choose the plan that best fits their calling
needs. The plans combine different charges for monthly access, usage, custom
calling features and, in some cases, varying amounts of pre-paid minutes of
usage.
 
      The Company also generates revenue from subscribers of other wireless
telephone systems when such subscribers ("roamers") place or receive calls over
its systems. Reciprocal agreements between the Company and other wireless
telephone system operators allow their respective subscribers to place calls in
most service areas throughout the country. Roamers are charged usage rates that
are generally higher than the regular service rate.
 
      The Company offers for sale or lease to its customers a wide variety of
wireless telephones, including mobile, transportable and fully portable
wireless telephones. The Company generally has offered significant discounts on
wireless telephones in an effort to attract domestic customers.
 
Distribution
 
      The Company uses both its own internal sales force and independent
agents, dealers and resellers to obtain customers for wireless telephone
service in the domestic systems. The Company controls its distribution
channels, including 65 retail outlets and 700 sales representatives in the
United States.
 
      The Company's internal sales force is paid on a salary plus commission
basis. Sales commissions are structured to take into account the length of the
subscriber's contract, the rate plan selected and the type of wireless
telephone sold. The Company also maintains an ongoing training program to
improve the effectiveness of its internal sales force. The Company's dealers
are independent contractors paid solely on a commission basis, and include
entities whose principal business is selling wireless telephones as well as
other entities whose customers may become wireless telephone users, such as
office supply stores, car stereo companies, auto parts stores, appliance stores
and department stores.
 
Marketing
 
      Centennial Rural Cellular markets its services and products under the
name "Centennial Wireless." Centennial Rural Cellular designs and implements
specific marketing strategies for each of its cellular systems using a variety
of billboard, radio and newspaper advertising to stimulate interest in cellular
telephone service, increase its customer base, increase cellular usage and
reduce subscriber cancellations. The Company's current marketing strategy in
its domestic markets is designed to generate continued net subscriber growth
and to focus on customers who are likely to generate higher monthly revenues,
primarily business users. More recently, as a result of broader acceptance of
wireless communications in general and the continued decline in the cost of
cellular handsets, Centennial Rural Cellular has added subscribers from an
increasingly wider range of occupations and demographics.
 
                                       85
<PAGE>
 
      In marketing its wireless telephone service, the Company stresses the
quality of its wireless telephone service, easy and rapid access to telephone
services, competitive prices, state-of-the-art features, and the local presence
of its customer service representatives and technical staff. In areas where the
domestic systems are in markets adjacent or proximate to one another, the
Company emphasizes that its own subscribers may make calls from anywhere in
these markets without incurring fees or charges in addition to the standard
usage and service fees which often are incurred when a customer "roams" from
one market to an adjacent market owned by a third party.
 
      The Company has introduced numerous innovative and effective marketing
programs tailored to its various subscriber bases within its domestic markets.
Such programs that Centennial has implemented include: "Option 7" (allowing
customers to make 7c per minute calls in an extended home service area during
off-peak hours for an additional $4.95 per month); "Forever Warranty"
(guaranteeing repair or replacement of a damaged phone within one hour at no
charge); "Express" (offering prepaid minutes of cellular usage to primarily
low-credit customers); "Companion Program" (allowing customers to add new
phones to an existing account for half the applicable basic service rate and to
share the included minutes); "Multistate Home Coverage Rates" (eliminating long
distance surcharges for calls made within the primary service area to anywhere
within an extended service perimeter); and "TotalFONE" (providing a package of
call waiting, call forwarding and conference calling features for $4.95 per
month).
 
Customer Service
 
      The Company believes that its ability to provide superior customer
service is a key factor in acquiring new customers and reducing churn among
existing customers. The Company maintains a customer service staff of
approximately 112 persons in its domestic systems. The Company has established
repair facilities and customers are able to report telephone service problems
24 hours a day in the Company's domestic markets. The Company believes that by
having convenient offices and repair facilities and a high ratio of customer
service personnel to customers it is better able to service customers and
monitor the technical quality of its wireless telephone system.
 
      The success of this emphasis on customer service is evidenced by the
Company's domestic average monthly churn rate of 1.8% (during fiscal 1998)
which the Company believes is lower than that of a typical cellular carrier and
demonstrates customer satisfaction with the Company's network.
 
Fraud Control
 
      Centennial has invested heavily in sophisticated anti-fraud technology
from Corsair that allows cell sites to identify the unique electronic
fingerprint of each customer's phone. This technology effectively eliminates
the threat of "cloning," as these fingerprints cannot be read by unauthorized
third parties. For an added level of protection, the Company uses Coral Systems
customer profiling software that recognizes customer calling patterns and
identifies serious deviations. Finally, Centennial Cellular Operating, together
with telephone companies in adjacent geographic areas, shares its data in a
cooperative effort to eliminate fraudulent use. As a result of these efforts
over the twelve-month period ended May 31, 1998, losses due to fraudulent
activity have declined to approximately 0.4% of service revenues, compared to
losses due to fraudulent activity of 2.6% of revenue for the year ended May 31,
1997.
 
Real-Time Billing System
 
      The Company employs a fully integrated billing system for its wireless
services that incorporates point-of-sale, credit checking, inventory, cash
handling, switch provisioning and customer service subsystems. This system also
interfaces with flexible invoice generation, a collections system and a fraud
detection system in order to enhance customer bill accuracy and presentation.
The domestic billing system confidentially processes the appropriate
information on mainframe computers located in Pennsylvania that each of the
 
                                       86
<PAGE>
 
Company's clusters is able to access and upload data using personal computers
communicating through a Wide Area Network. As a result of this system, the
Company minimizes its cost of processing.
 
Suppliers and Equipment Partners
 
      The Company does not manufacture any customer or network equipment. The
high degree of compatibility among different manufacturers' models of handsets,
PCS phones and network facilities equipment allows the Company to design,
supply and operate its systems without being dependent on a single source of
such equipment. The Company currently purchases handsets primarily from
Motorola, Inc., Ericsson, Inc. and Nokia Telecommunications, Inc. The Company
currently purchases network equipment from Northern Telecom, Lucent
Technologies Inc., Harris, Inc. and Nokia Telecommunications, Inc.
 
Digital Wireless Technology
 
      Over the next decade, it is expected that wireless telephones will
gradually convert from analog to digital technology. This conversion is due in
part to capacity constraints in many of the largest cellular markets, such as
Los Angeles, New York and Chicago. As carriers reach limited capacity levels,
certain calls may be unable to be completed, especially during peak hours.
Digital technology increases system capacity and simultaneously provides a
network architecture that supports delivery of revenue-enhancing features and
services, including extended battery life on hand-held phones, improved overall
average signal quality, improved call security, intelligent system selection
and zone billing, alphanumeric paging, Internet-based electronic mail receipt,
caller identification, voice mail messaging display and the ability to provide
data/facsimile transmission services. The conversion from analog to digital
technology is expected to be an industry wide process that will take a number
of years.
 
      The Company is in the process of upgrading its domestic cellular
telephone systems from analog to digital technology. In its domestic markets,
the Company expects to deploy the TDMA standard, which has been adopted and
certified by the CTIA. TDMA is the digital standard being deployed nationally
by AT&T, and is supported by all of the major infrastructure providers, such as
Nortel, Lucent and Ericsson. TDMA encodes three voice calls on a single 30 KHz
channel, effectively yielding a spectral-efficient, three-fold increase in
system capacity. In Puerto Rico, the Company utilizes the CDMA standard, which
is a spread-spectrum technology.
 
      The implementation of digital technology will be fundamentally directed
by subscriber demand for secure and confidential communications, the
introduction of new cellular telephone services such as message waiting and
calling line identification, and the delivery of data communications. Where
cell sites are not yet at their maximum capacity of radio channels, the Company
is adding digital channels to the network incrementally based on the relative
demand for digital and analog channels. Where cell sites are at full capacity,
analog channels are being removed and redeveloped to expand capacity elsewhere
within the network and replaced in such cell sites by digital channels. The
implementation of digital cellular technology over a period of several years
will involve modest incremental expenditures for switch software and possible
significant cost reductions as a result of reduced purchases of radio channels
and a reduced requirement to split existing cells. However, as indicated above,
the extent of any implementation of digital radio channels and the amount of
any cost savings ultimately to be derived therefrom will depend primarily on
subscriber demand. In the ordinary course of business, equipment upgrades at
the cell sites have involved purchasing dual mode radios capable of using both
analog and digital technology.
 
      The benefits of digital radio channels can only be achieved if
subscribers purchase cellular telephones that are capable of transmitting and
receiving digital signals. Currently, such telephones are more costly than
analog telephones. The widespread use of digital cellular telephones is likely
to occur only over a substantial period of time and there can be no assurance
that this technology will replace analog cellular telephones. In
 
                                       87
<PAGE>
 
addition, the FCC currently requires cellular licenses to provide analog
service to subscribers desiring such service and most of the Company's existing
subscribers have cellular telephones that exclusively utilize analog
technology. Thus, it will be necessary to continue to support, and if necessary
increase, the number of analog radio channels within the network for many
years.
 
      The widespread availability of dual-mode or tri-mode phones capable of
transmitting and receiving calls using different wireless technologies may also
increase the usage of the Company's system. Traditionally, a cellular handset
is only capable of carrying calls from an analog and possibly one type of
digital network. Thus, a subscriber to a TDMA network can only place calls over
other TDMA networks. With multi-mode phones, a subscriber can place a call on
any network recognized by the phone. Thus, if a phone recognizes TDMA, CDMA,
and analog, a subscriber can place a call on any of these networks. One direct
impact of the availability of these phones is roaming revenue. A subscriber on
a CDMA network, for example, will be able to roam on the Company's analog or
TDMA networks, thus increasing the Company's roaming revenues.
 
Construction, Operation and Development
 
      The Company operates its Domestic Wireless Telephone Systems pursuant to
29 cellular licenses which it owns. Wireless telephone technology is based upon
the radio coverage of a given geographic area by a number of overlapping
"cells." Each cell contains a transmitter-receiver at a "base station" or "cell
site" that communicates by radio signal with wireless telephones located in the
cell and is connected to a mobile telephone switching office (the "MTSO"),
which, in turn are connected to the local landline telephone network. Since
wireless telephone systems are fully interconnected with the landline telephone
network and long distance networks, subscribers can receive and originate both
local and long distance calls from their wireless telephones.
 
      In accordance with its strategy of developing market clusters, the
Company has selected wireless switching systems that are capable of serving
multiple markets with a single MTSO and has already implemented this strategy
in most of its markets. The Domestic Wireless Telephone System is designed to
facilitate the installation of equipment which will permit microwave
interconnection between the MTSO and each cell site. In addition, microwave
facilities can be used to connect separate wireless telephone systems to the
same switch, which may reduce the total cost of the equipment necessary to
operate both systems. Where the Company has deemed it appropriate, the Company
has implemented microwave services in the Domestic Wireless Telephone Systems.
The other systems rely upon landline telephone connections to link cell sites
with the MTSO. Although the installation of microwave network equipment
requires a greater initial capital investment, a microwave link enables a
wireless telephone system operator to avoid the current and future charges
associated with leasing telephone lines from the landline telephone company and
generally improves system reliability. Subject to the availability of
appropriate microwave sites, the Company may replace the leased lines in the
Domestic Wireless Telephone Systems with microwave links as the volume of calls
in each system makes the use of such microwave links more cost efficient.
 
      The Company hires consulting engineers and telecommunications general
contractors to aid in the design and management of the construction and
expansion of its wireless telephone system. By doing so, the Company believes
it improves the overall system engineering and construction quality and reduces
the expense and time required to make and keep the systems operating at the
high level of technical quality.

Puerto Rico Wireless Services
 
Generally
 
      Centennial de Puerto Rico holds one of two MTA licenses to provide
broadband PCS in the Commonwealth of Puerto Rico and the U.S. Virgin Islands.
Centennial de Puerto Rico acquired the 30 MHz Block B broadband PCS license for
the Puerto Rico-Virgin Islands MTA from the FCC for a purchase price of
approximately $55 million in fiscal 1996. These markets contain approximately
3.8 million Pops. As of November 30, 1998, Centennial de Puerto Rico had
approximately 98,700 PCS subscribers and approximately 14,200 subscribers for
its wireless local loop services. The Company believes that it has an estimated
13% market share in Puerto Rico based upon the number of wireless subscribers
and an estimated 25% market share based upon revenues. The Company intends to
review the possibility of building a wireless network in the U.S. Virgin
Islands.
 
      The PCS and wireless local loop services utilize Centennial de Puerto
Rico's CDMA, digital PCS network. This network provides all of the increased
functionality that is typically associated with PCS service in the U.S. The
Company's CDMA technology operates on the 2 GHz radio frequency band and allows
the Company to offer a higher quality of voice transmission than the systems
currently used by the Company's competitors. The Company believes that CDMA
offers approximately eight times the capacity of a typical analog system and
three times the capacity of a TDMA system. CDMA also provides greater fraud and
privacy protection than other wireless technologies.
 
PCS Products and Services
 
      Centennial de Puerto Rico's fully digital CDMA network enables it to
provide a broader range of services and features than its two incumbent
cellular competitors. The Company tailors its service offerings to the demands
of the high usage subscriber in the Puerto Rico market and includes the
following:
 
     .  Integrated voicemail and paging
 
     .  Caller ID
 
     .  Use of mobile phone included free of charge
 
     .  "Forever Warranty" (which guarantees phone repair or replacement)
 
     .  Detailed billing (which itemizes all local and long distance
        charges)
 
      The Company also offers "Companion Program" (allowing customers to add
new phones to an existing account for $16.95 per month per phone and to share
the included minutes) and "Alcance" (offering prepaid minutes of wireless usage
to primarily no or low-credit customers). Centennial de Puerto Rico's "Alcance"
customers purchase a used and fully depreciated phone from the Company, pay an
activation fee and prepay for a certain number of minutes of wireless usage.
When a customer's balance of available minutes runs low, the customer receives
two notifications over the phone and may choose to be connected to a service
representative of the Company to prepay for additional minutes of service.
 
      The Company is responsible for the quality, pricing and packaging of its
wireless service. The Company offers several pricing plans and customers are
able to choose the plan that best fits their calling needs. The plans combine
different charges for monthly access, usage, custom calling features and
varying amounts of included minutes of usage. A customer may also purchase
additional calling features individually. The Company's premium calling
features, which the Company can provide at little or no incremental cost, have
achieved significant market penetration. As of November 30, 1998, 91% of
Centennial de Puerto Rico's customers had purchased loss protection for their
PCS phones, 59% of its customers had elected detailed
 
                                       89
<PAGE>
 
billing, and 59% had chosen the Super Feature, which includes call transfer,
call waiting, conference calling and caller ID. Thirty percent of Centennial de
Puerto Rico's customers subscribed for the voicemail feature. Centennial de
Puerto Rico's customers sign agreements acknowledging that they will be billed
for a minimum of six months on their accounts.
 
      Centennial de Puerto Rico has a roaming agreement with Sprint, which
commenced in September 1998. This agreement allows the Company's customers in
Puerto Rico to use their phones in Sprint's PCS coverage areas in the U.S. and
allows Sprint's customers to use their phones in Puerto Rico. The Company is
currently negotiating similar PCS roaming agreements with Primeco and Codetel.
Roaming is not expected to generate significant revenues in the current fiscal
year.
 
      The Company is in the process of beta testing a system that would allow
the Company to offer its wireless customers the ability to transmit data at
speeds of 14.4 Mbps over its system. This service would, for instance, allow
PCS and wireless local loop customers to receive and send email, and allow
businesses to send and receive sales information and access banks to complete
ATM transactions from remote locations. The Company does not believe that any
other wireless provider currently offers data transmission over a CDMA system.
The Company intends to evaluate the capacity required to complete such
transmissions to determine whether to offer this service to its customers.
 
Wireless Local Loop Services
 
      The Company introduced a wireless local loop system in Puerto Rico in
August 1997. A wireless local loop customer leases or purchases a wireless
phone from the Company, which is then plugged into an electric outlet. The
phone works the same as any other PCS phone, although it is intended to be used
in just one location. The service initially targeted private residences that
did not have access to wireline service from the PRTC or that wanted an
additional telephone line. However, in response to demand from business
customers, the Company began to offer service to businesses. The Company
believes its wireless local loop service provides an attractive alternative to
the PRTC for local business telephone service, particularly to those customers
who make most of their calls outside their PRTC local calling area. The Company
is able to leverage its existing PCS infrastructure to provide digital local
loop service at a low incremental cost wherever its PCS coverage already
exists.
 
      As of November 30, 1998, the Company had approximately 14,200 subscribers
to its wireless local loop service, which is marketed to residential customers
under the brand name "HomePhone" and to businesses under the name
"BusinessPhone." The wireless local loop service generated approximately $3.8
million in revenues for the fiscal year ended May 31, 1998, and an additional
$6.3 million in revenues in the six months ended November 30, 1998. The average
customer generates approximately $87 in monthly revenues during three months
ended November 30, 1998. The Company requires its new wireless local loop
customers to sign a one-year contract.
 
Marketing
 
      The Company markets its wireless services and products in Puerto Rico
under the name "Centennial de Puerto Rico." The Company designs and implements
specific marketing strategies for its wireless systems using a variety of
television, billboard, radio and newspaper advertising to stimulate net
subscriber growth and to focus on customers who are likely to generate higher
monthly revenues, primarily business users. The Company's marketing
expenditures for the six months ended November 30, 1998 totaled approximately
$10.2 million, and the average acquisition cost per subscriber during the same
period was approximately $185. Acquisition costs are determined for a period by
dividing selling and marketing expenses and cost of equipment sales (net of
associated revenue) by the gross wireless customers added during such period.
 
                                       90
<PAGE>
 
      In marketing wireless telephone service, the Company stresses the quality
and clarity of its wireless telephone service, easy and rapid access to
telephone services, competitive prices, state-of-the-art features and anti-
fraud protection. Subscribers in Puerto Rico are offered packages that include
integrated voice mail and pager service, caller ID, free usage of a PCS phone
and services in which the first minute of incoming calls are free. Customers
may also purchase additional calling features individually.
 
      The Company maintains 52 retail outlets throughout Puerto Rico, of which
six are stores located in the major metropolitan areas of the island. The
remainder are kiosks, which the Company has constructed in malls, supermarkets
and other large retail centers at a capital cost of approximately $4,000-8,000
each. Each outlet offers the full range of the Company's wireless services and
serve the needs of the Company's residential and small business customers. The
Company uses its internal sales force to market its services to larger
businesses throughout Puerto Rico.
 
      The Company's 315 sales representatives are paid on a salary plus
commission basis. Charge backs are taken from sales commissions in the event
that customers terminate service prior to the expiration of the minimum six-
month billing period. Sales commissions are structured to take into account the
rate plan and premium services selected. The Company maintains an ongoing
training program to improve the effectiveness of its sales force.
 
      The Company provides its subscribers with a basic PCS phone, which must
be returned when the service is disconnected. Customers are also able to choose
more expensive phone models in return for an additional fee. They can also
purchase used phones from the Company. The Company believes that providing free
phone usage is necessary due to the relative expense of PCS phones
(approximately $300) in comparison to the cost of typical cellular phones which
are given away as part of service plans by the Company's competitors
(approximately $100). The cost of the phones, which are owned by the Company,
are depreciated over an 18-month period. The Company refurbishes a PCS phone
that is returned before it has been fully depreciated and then resells it to a
new customer.
 
Lambda CLEC
 
Generally
 
      Lambda CLEC, a wholly owned subsidiary of the Company, is the only local
exchange carrier competing with the PRTC in offering local, long distance and
enhanced data services to business customers. The PRTC's inability to provide
broadband connectivity to businesses in a timely manner has enabled Lambda CLEC
to attract many large businesses, most of which have entered into multi-year
contracts with the Company for fiber optic connections. Its customers include
MCI, Banco Santander and El Nuevo Dia, Puerto Rico's largest newspaper. As of
November 30, 1998, Lambda CLEC provided services over 292 route miles of fiber.
For the six months ended November 30, 1998, Lambda CLEC had annualized EBITDA
of $9.8 million after only 21 months of operations.
 
      Lambda CLEC offers services in many locations as the Company's fiber
optic network runs through the major business and population centers of Puerto
Rico. The cost of leading the fiber optic cable from the street into an office
building is typically paid by the customer requesting the service. The
Company's customers are often willing to pay this price in return for the
faster installation times and service provided by the Company. Once a cable has
been installed in a building, the Company then markets its CLEC service to
other smaller businesses in the building. The Company is usually able to
install the necessary fiber optic cable and connect service within 60 days,
whereas the Company believes that some customers of the PRTC may have to wait
significantly longer to have additional lines of service installed. The Company
believes it offers timely and reliable service to its business customers as
well as competitive pricing.
 
                                       91
<PAGE>
 
      Lambda CLEC generated approximately $4.7 million in revenues for the
fiscal year ended May 31, 1998 and $8.8 million in revenues during the six
months ended November 30, 1998. The service provided approximately 41.7 million
MOUs to its customers in November 1998, an increase of 87% over the MOUs
provided in May 1998. Lambda CLEC's average customer generated approximately
$16,000 in monthly revenues during the month ended November 30, 1998. The churn
rate for these customers is close to zero, which the Company believes is due to
the cost and time involved in the design and installation process and the fact
that most of the Company's CLEC customers have long-term contracts.
 
Products and Services
 
      The Company's products and services are designed to appeal to the
integrated communications needs of its target customers.
 
     .  Local Services. The Company provides local dial-tone service to
        customers, which allows them to complete calls in the local
        calling area and to access a long distance calling area. The
        Company's network is designed to allow a customer to easily
        increase or decrease capacity and alter enhanced services as the
        communications requirements of the business change. In addition to
        its core local services, the Company also provides access to
        third-party directory assistance and operator services.
 
     .  Long Distance Services. The Company provides domestic and
        international long distance services for completing intra-island
        and international calls. Long distance service is offered as an
        additional service to the Company's local exchange customers. Long
        distance calls which do not terminate on the Company's network are
        passed to long distance carriers which route the remaining portion
        of the call. The Company has an agreement with Telefonica de
        Espana, a Spanish long distance company, pursuant to which the
        Company can offer its customers competitive international rates.
        The Company's customers can receive volume discounts based upon
        their total usage of both local and long distance calling. The
        Company's ability to integrate local and long distance services
        allows it to aggregate customers' monthly recurring, local usage
        and long distance charges on a single, consolidated invoice.
 
     .  Enhanced Services. In addition to providing typical enhanced
        services such as voice mail, call transfer and conference calling,
        the Company offers additional value-added enhanced services to
        complement its core local and long distance services. These
        enhanced service offerings include:
 
             .  Access to Internet Services: The Company maintains a server
                that enables its customers direct access to the Internet. The
                Company allows customers to access the Internet through other
                ISPs in Puerto Rico.
 
             .  Data Networking Services: The Company can provide high-speed,
                broadband services to use for data and Internet access such as
                Integrated Services Digital Network (ISDN) and Primary Rate
                Interface (PRI). The Company can provide for the transmission
                of voice and data over dedicated circuits ("private lines")
                and can install T-1, DS-1, DS-3 and OC-3 lines and provide E-1
                to T-1 conversion services.
 
             .  Specialized Application Services: The Company can create
                products and services that are tailored for target industries
                with special telecommunications needs such as the hospitality
                industry. These services typically include non-measured rate
                local calling, expanded local calling area, discounted long
                distance rates and tailored trunking configurations.
 
      In February 1999, Lambda CLEC began offering long distance services to
both residential and business customers. In March 1999, Lambda CLEC will also
begin offering direct Internet access to its customers.
 
                                       92

Marketing
 
      The Company has capitalized on the current lack of competitive services
and pricing structures in Puerto Rico by positioning its CLEC service as a
high-quality provider of integrated communications services, particularly for
business customers with high usage patterns and sophisticated communications
needs. Prior to the introduction of Lambda CLEC service, wireline telephone
services were only available in Puerto Rico from the PRTC. The Company believes
it offers prompt installation and timely and reliable service to its business
customers over its all digital network as well as competitive pricing.
 
      The CLEC service is marketed through a direct sales force of highly
trained account representatives. Currently, eight representatives primarily
target businesses that are heavy users of communications services and demand
prompt service. To further increase market awareness of its products and
services, the Company also conducts seminars targeting specific industry groups
that the Company believes would benefit from its services.
 
Real-Time Billing
 
      The preparation of bills for Puerto Rico customers is outsourced pursuant
to an agreement with ALLTEL Telecom Information Services, Inc. The preparation
of bills for Lambda CLEC's services are outsourced pursuant to an agreement
with Saville. Centennial de Puerto Rico is currently examining alternative
billing arrangements and vendors which would allow it to provide a consolidated
bill to customers utilizing both wireless and wireline services from Centennial
de Puerto Rico.
 
Suppliers and Equipment Partners
 
      Centennial de Puerto Rico currently purchases PCS phones primarily from
QualComm Incorporated and Sony Corporation and currently purchases network
equipment from Lucent Technologies Inc., Fujitsu and Alcatel.
 
Construction, Operation and Development
 
      Construction of wireless telephone systems is capital intensive,
requiring a substantial investment for land and improvements, buildings,
towers, MTSOs, cell site equipment, microwave equipment, engineering and
installation. Until technological limitations on total capacity are approached,
additional wireless telephone system capacity can normally be added in
increments that closely match demand and at less than the proportionate cost of
the initial capacity. However, once capacity on a switch has been reached, a
new switch must be added at significant cost. The Company anticipates that the
volume of calls carried on its system will require a second switch to be added
in the spring of 1999. The switch will be configured to handle both wireless
and wireline calls and will cost approximately $10 million. The FCC has
established construction benchmarks which require that 30 MHz broadband PCS
systems, including Centennial de Puerto Rico's PCS system, serve at least one-
third of the population in their licensed area within five years of being
licensed and two-thirds of the population in their licensed area within ten
years of being licensed. The Company, having substantially completed
installation of its initial system, believes it is in compliance with these
requirements. In addition, broadband PCS spectrum is currently used by
incumbent co-channel point-to-point microwave users. As a general proposition,
broadband PCS licensees are required to pay the costs associated with the
relocation of these existing microwave users to other portions of the radio
spectrum or other media.
 
      Both the wireless and CLEC services utilize the Company's switch and its
state-of-the-art fiber optic network, which contains over 292 route miles of
fiber throughout the island of Puerto Rico. The digital PCS network uses CDMA
technology to transmit its calls. The system is served by a Lucent Technologies
5 ESS switch for both wireless and wireline services. This single platform is
connected to the Company's digital CDMA network as well as its self-healing
(redundant) fiber optic SONET network, which operates at
 
                                       93
<PAGE>
 
2.5 billion bits per second and is capable of supporting 30,000 simultaneous
conversations. The SONET architecture minimizes the risk of downtime in the
event of a fiber cut and provides customers with high security and reliability.
The cost of leading the fiber optic cable from the street into an office
building is typically paid by the customer requesting the service.
 
      The Company's wireless telephone system is designed to facilitate the
installation of equipment which permits microwave interconnection between the
MTSO and each cell site. In the San Juan/Caguas area, the Company's cell sites
are connected directly to the Company's fiber optic network. Outside the area,
calls from cell sites are transmitted to the MTSO by microwave transmitters.
Using a microwave network enables the Company to avoid laying fiber optic cable
in areas where the Company believes its installation would not be cost
effective.
 
      The total cost to Centennial de Puerto Rico of the acquisition and build-
out of the infrastructure of the PCS and CLEC system (including the purchase of
equipment and installation services, a license fee that the Company has paid of
approximately $55 million and the upgrade of cell sites and call switching
equipment) has been approximately $184.6 million in the aggregate through
fiscal 1998. It is anticipated that approximately $50.0 million will be
expended in connection with the build-out through fiscal 1999.
 
      Recent improvements to the system have boosted the quality of the average
subscriber's experience, yielded a low dropped rate of approximately 2% and an
approximately 97% call completion rate, based on calls made during the three
months ended August 31, 1998. As of August 31, 1998, the Company had completed
120 of 138 planned cell sites and plans to complete 18 additional cell sites
and install 17 repeaters before the end of the fiscal year ending May 31, 1999.
Repeaters are used to amplify signals between cell sites and reduce the need
for additional sites.
 
      The Company hires consulting engineers and telecommunications general
contractors to aid in the design and management of the construction and
expansion of its wireless and wireline telephone systems. By doing so, the
Company believes it improves the overall system engineering and construction
quality and reduces the expense and time required to make and keep the systems
operating at a high level of technical quality.
 
Puerto Rico Interconnection Agreements
 
      The Company has entered into an interconnection agreement with the PRTC
that covers service throughout Puerto Rico. This agreement expires in March
1999. The Company is currently negotiating a new interconnection agreement with
the PRTC. Where an interconnection agreement cannot be reached on terms and
conditions satisfactory to the Company, the Company may pursue binding
arbitration of any disputes before the Puerto Rico utility commissions. There
can be no assurance, however, that the Company will be able to negotiate
interconnection agreements on terms and conditions satisfactory to the Company
or to renew existing interconnection agreements as they expire. A decision by
the United States Court of Appeals for the Eighth Circuit vacating several of
the FCC's rules creates uncertainty about the rules governing pricing, terms
and conditions of interconnection agreements. As a result of this decision,
which has been appealed to the Supreme Court, and a pending review of this
issue by the FCC, negotiations and enforcement of such agreements could become
more difficult and protracted, and renegotiation of existing agreements could
be required.

                                  Competition
 
Overview
 
      The Company currently competes with one cellular licensee in each
geographic area where it operates. Many of these licensees are larger and have
greater financial resources than the Company. In addition, the Company competes
in many of its markets with providers of other wireless communications services
such as PCS, ESMR and paging. The Company also competes with local landline
telephone companies for telephone usage by customers. Competition for
subscribers among wireless providers is based principally upon the services and
enhancements offered, the technical quality of the system, sound quality,
reliability of connections, customer service, system coverage, capacity and
price.
 
      The following chart lists the Company's principal cellular and PCS
competitors in each of its clusters and the major adjoining operators.

</TABLE>
 
      The Company's two main competitors for wireless services in the Puerto
Rico market are CoreComm, a publicly traded U.S. company, and the PRTC, which
is currently owned by the Commonwealth of Puerto Rico but which has agreed to
sell a significant stake to GTE Corporation, a U.S. telecommunications company
which will control the PRTC's board of directors. The parties' public
statements indicate that they expect the transaction to close during the first
quarter of 1999. In July 1998, GTE agreed to merge with Bell Atlantic. Both
CoreComm and PRTC were earlier entrants into the Puerto Rico wireless market
and currently hold subscriber market shares of approximately 47% and 40%,
respectively. CoreComm and PRTC offer both analog and digital cellular service
(using TDMA technology) to their subscribers and offer greater roaming capacity
to their customers traveling outside Puerto Rico, as both have roaming
agreements with major cellular providers in the U.S. The Company currently
offers roaming ability in the U.S. pursuant to an agreement with Sprint.
 
      PRTC is the primary wireline telephone service provider in Puerto Rico
and its wireline services are also a source of competition for the Company's
services. In addition, both CoreComm and the PRTC are substantially larger and
have greater resources than the Company, and there can be no assurance that the
 
                                       95
<PAGE>
 
Company will be able to compete effectively with them or other future entrants
into the Puerto Rico telecommunications market. Both GTE and Bell Atlantic also
have substantially greater resources than the Company and may make changes to
improve service which, in turn, may strengthen the PRTC's competitive position.
 
Competition From Resellers
 
      The FCC requires all cellular and PCS licensees to provide service to
resellers, who sell service to customers but do not hold an FCC license or
cellular facilities for the provision of these services. Instead, a reseller
buys blocks of telephone numbers from a licensed carrier and resells service to
the public through its own distribution methods. Thus, a reseller may be both a
customer of a cellular or PCS provider and also a competitor. The Company does
not know of any significant resellers currently operating in competition with
the Company's domestic systems. However, the Company may begin experiencing
resale competition given that many long-distance companies have announced plans
to integrate resold wireless services into their long-distance offerings.
 
      Ameritel, acting as a reseller, is currently offering cellular services
at Radio Shack stores throughout Puerto Rico. The Company does not know of any
other significant cellular resellers currently operating in competition with
the Company's PCS system.
 
Competition From Broadband PCS Systems
 
      Among other possible uses, broadband PCS is capable of providing a two-
way mobile voice and data telephone service that is similar to cellular
service. A broadband PCS system is a wireless communications system that
utilizes digital technology that allows it to compete effectively with cellular
systems, particularly in densely populated areas. Digital technology provides
certain advantages over the analog technology currently used by the Company in
most of its cellular markets, including increased system capacity, improved
overall signal quality and increased call security. Broadband PCS licenses are
awarded by competitive bidding. Although a number of broadband PCS systems are
currently in operation, service from these systems is generally limited to
relatively urban areas around the country. To date, the Company has experienced
only minor competition from PCS licensees, likely in part due to the rural
character of the Company's markets.
 
      It is uncertain what effect broadband PCS will have on the Company's
wireless telephone systems which it operates pursuant to cellular licenses. The
FCC revised its rules to authorize cellular licensees to provide any PCS-type
services on their channels without prior notification to the FCC. Management of
the Company believes that technological advances in present cellular telephone
technology, including the use of digital technology, in conjunction with build-
out of the present cellular systems throughout the nation with cell splitting
and microcell technology, will allow cellular licensees to provide essentially
the same services as the services that PCS providers are expected to offer, but
there can be no assurance that this will happen.
 
      The FCC has issued a 30 MHz broadband PCS license for the Puerto Rico-
U.S. Virgin Islands MTA to TeleCorp. The FCC has also issued as many as four
broadband PCS licenses for the San Juan, Puerto Rico BTA, the Mayaguez-
Aguadilla-Ponce, Puerto Rico BTA and the U.S. Virgin Islands BTA to other
entities, including a 10 MHz license to the PRTC. If these licenses become
operational, these broadband PCS systems will present additional competition to
the Company's PCS operations in Puerto Rico. The Company does not believe that
TeleCorp, which is in the early stages of construction of its PCS system as
part of a franchise relationship with AT&T Wireless Services, will achieve
significant network coverage within the next twelve months.
 
      New PCS competitors will face a number of significant hurdles in building
out their systems in Puerto Rico, including the development of a "backhaul"
network connecting their cell sites with their switch. A competitor may (i)
utilize PRTC's network, (ii) construct its own network, (iii) utilize the
Company's fiber
 
                                       96

optic network or (iv) choose a combination of these methods. The Company
believes that few competitors will choose to build their own networks because
of the significant cost and time constraints, nor will they choose to contract
with the PRTC because of its poor reliability and the long wait times required
for new T-1 service to be added. Thus, the Company believes that some of its
competitors may seek to contract with the Company for backhaul services.
 
Wireline Competition
 
      Centennial de Puerto Rico's primary competitor for wireline service is
the incumbent provider, the Puerto Rico Telephone Company. GTE, which recently
entered into a merger agreement with Bell Atlantic, has agreed to buy a
significant stake in the PRTC and will control PRTC's board of directors. The
growth of the Company's market presence will depend upon its ability to obtain
customers that are underserved by the PRTC or looking for an alternative.
Because of the Company's ability to provide more timely installation and
service, the Company has primarily attracted customers on the basis of quality
and service rather than price. KMS, a U.S. corporation based in New Jersey, has
announced plans to set up a fiber optic network in Puerto Rico to offer
Internet access and data transmission, although it has not yet commenced
construction.
 
Competition From Other Technologies
 
      Potential users of cellular systems may choose instead to obtain
communications services provided over other current or developing technologies.
PCS operators providing digital communications technology may compete with
cellular service with respect to rates, enhanced privacy and additional
features such as electronic mail and built-in paging capabilities. One-way
paging or beeper services that feature voice messages and data display as well
as tones may be adequate for potential subscribers who do not need to speak to
the caller. In the future, cellular service may also compete more directly with
traditional landline telephone service providers.
 
      ESMR and other land mobile radio systems, such as those historically used
by taxicabs and tow truck services, and other communications services that have
the technical capability to handle mobile telephone calls (including
interconnection to the landline telephone network), may provide competition to
cellular and PCS services in certain markets. Beginning in February 1991, the
FCC has permitted several large operators of ESMR systems to construct and
operate ESMR systems. This digital technology incorporates characteristics of
cellular technology, including multiple low power transmitters and
interconnection with the landline telephone network, to provide wide-area
mobile communications services that substantially increase the system's
customer capacity. ESMR service may compete with cellular service by providing
digital communication technology, lower rates, enhanced privacy and additional
features such as electronic mail and built-in paging. The FCC has auctioned,
and will auction in the future, licenses in the 800 and 900 MHz frequency bands
that are intended to promote wide-area ESMR systems that would be more
competitive with other wireless services, including cellular. Nextel is the
primary provider of such services.
 
      The FCC has also made available other frequency bands that may be used
for the provision of cellular-like services. GWCS and WCS are two such services
that are in their infancy. Although the FCC has proposed technical rules for
WCS that will make commercial mobile services like cellular and PCS infeasible,
there can be no assurance that the FCC will not adopt more flexible WCS
technical rules that will enable WCS licensees to provide service comparable to
cellular and PCS services.
 
      As a result of the above, the Company's cellular operations may face
increased competition from providers of other communication technologies and
services. The Company cannot predict the success of such competing technologies
or their operational abilities. While some of these technologies are currently
operational, others are operational on only a limited basis or are not yet
operational. There can be no assurance that the Company will be able to provide
or that it will choose to pursue, depending on the economics thereof, services
and features in addition to those already provided. While the Company believes
that competition from other technologies will increase over both the short and
long terms, it also believes that the development of
 
                                       97
<PAGE>
 
economically-proven, traditional cellular technology and the expansion of its
cellular clusters is its best strategy. Nonetheless, there can be no assurance
that one or more of the technologies currently used by the Company will not
become technologically or economically obsolete in the future.
 
                                   Regulation
 
Overview
 
      The wireless telecommunications industry is subject to extensive
governmental regulation on the federal level and to varying degrees on the
state level. Many aspects of such regulation have been affected by enactment of
the Telecommunications Act of 1996 (the "Telecom Act") and are currently
subject to administrative rulemakings that are significant to the Company.
Neither the outcome of these rulemakings nor their impact on the wireless
telecommunications industry can be predicted at this time. The following is a
summary of the federal laws and regulations that materially affect the wireless
telecommunications industry, as well as a description of certain state and
local laws and regulations. Puerto Rico is subject to U.S. laws and
regulations, including regulation by the FCC as well as local
telecommunications laws. This section does not purport to be a summary of all
present and proposed federal, state, and local regulations and legislation
relating to the wireless telecommunications industry.
 
Federal Regulation
 
      The FCC has granted two 25 MHz licenses to operate cellular telephone
systems in each of the 306 MSAs and the 428 RSAs. The FCC has also granted two
30 MHz licenses to operate broadband PCS systems in each of 51 defined MTAs and
one 30 MHz and three 10 MHz licenses in each of 493 BTAs, which are component
parts of MTAs.
 
      The licensing, ownership, construction, operation, and sale of
controlling interests in wireless telephone systems is governed by the
Communications Act and FCC rules and regulations. The FCC has promulgated rules
and regulations governing, among other things, applications to construct and
operate cellular and PCS systems, applications to transfer control of or assign
cellular and PCS licenses, and technical and operational standards for the
operation of wireless telecommunications systems.
 
      Pursuant to FCC rules, no entity may own, directly or indirectly, more
than a 5% interest in competing cellular systems in a market, unless such
ownership poses no competitive threat. The FCC also prohibits an entity from
having an attributable interest (as defined in FCC rules) in more than 45 MHz
of PCS, cellular, and ESMR spectrum if the service areas associated with such
spectrum overlap significantly. As a result, the Company must closely monitor
its investments, as well as the interests held by shareholders holding 5% or
more of Company stock, to ensure that the Company does not run afoul of either
rule.
 
      The FCC licenses cellular systems in accordance with geographically
defined market areas. In each market, the frequencies allocated for cellular
use are divided into two equal 25 MHz blocks. The FCC issued one license for
each frequency block in every cellular market. The initial cellular licensees
in each cellular market received the exclusive right to serve the market over
its allotted frequencies for five years after the grant of the licensee's
initial construction permit. At the end of this five-year period, any entity
meeting the FCC's eligibility criteria, including the initial licensees, may
request FCC authority to serve areas unserved by either of the initial
licensees. These five-year periods have expired in most markets and the FCC has
authorized parties other than the initial licensees to serve many areas
unserved by the initial licensees.
 
      The Communications Act requires FCC approval for transfers of controlling
interests in any license or construction permit. The Communications Act also
generally prohibits foreign persons or entities from controlling FCC licenses
or holding interests of more than 25% in an FCC licensee. The FCC will
generally
 
                                       98
<PAGE>
 
permit additional indirect ownership in excess of the statutory 25% benchmark
where that interest is to be held by an entity or entities from member
countries of the World Trade Organization. For investors who are not from such
countries, however, the FCC will determine whether the home country of the
foreign investor extends reciprocal treatment to U.S. entities called
"equivalent competitive opportunities" to U.S. entities. If such opportunities
do not exist, it is unlikely that the FCC will permit investment beyond the 25%
benchmark. Although there is no guarantee that requests for FCC approval of
transfers (especially those involving foreign ownership) will be granted or
acted on promptly, the Company has no reason to believe that any future
transfer applications it may file would not be approved. The FCC issued an
order granting the transfer of control of all necessary cellular licenses on
October 9, 1998. This order became final on November 18, 1998.
 
      Congress amended the Communications Act in 1996 and required state public
utilities commissions and/or the FCC to implement policies that mandate
reciprocal compensation between local exchange carriers and wireless telephone
service providers. On August 1, 1996, the FCC adopted rules implementing these
policies, but various aspects of the Order have been overturned by a federal
court and the decision remains subject to further judicial review. The FCC's
Order remains in effect, however, with regard to interconnection between local
exchange companies and certain wireless telecommunications carriers, including
cellular and PCS licensees. While it is too soon to predict the actual effect
of the FCC's Order, the Company believes that the new rules are likely to
reduce the interconnection expenses incurred by the Company. These
interconnection expenses currently are a major component of the Company's cost
structure.
 
      The cellular and PCS licenses held by the Company were granted for ten
year terms and are renewable for additional ten year terms. Near the conclusion
of the license term, licensees must file FCC applications requesting renewal of
their licenses. The original license terms for many of the Company's cellular
licenses have already expired, but to date the FCC has renewed each license for
a new ten-year term. If another entity files an application seeking a license
the Company is renewing, the FCC will determine whether the Company is entitled
to a renewal expectancy. A renewal expectancy will be granted if the Company
demonstrates that it has provided substantial service (i.e., better than
mediocre) and that it has substantially complied with FCC rules and
regulations. If a renewal expectancy is granted, the competing application will
not be entertained and the Company's license will be renewed.
 
      Similar renewal rules govern the Company's PCS license. In addition, the
Company must construct facilities that offer coverage to one-third of the
population within its PCS service area within five years, and two-thirds of the
population before the expiration of the license term. If the Company is unable
to satisfy these requirements, its PCS license will be subject to revocation.
 
      Applications for FCC licenses, including renewal applications, may be
denied or licenses revoked if the FCC determines that an entity lacks the
"character" qualifications needed to be a licensee. In making this
determination, the Commission considers whether the entity has been the subject
of adverse judicial or administrative findings relating to: felonies; the
possession or sale of unlawful drugs; fraud; misrepresentation; antitrust
violations; unfair competition; employment discrimination; or violations of the
Communications Act or FCC rules.
 
      The FCC requires wireless telephone service providers to satisfy a number
of technical and reporting requirements. For example, providers must coordinate
frequency usage to ensure that harmful technical interference is not created
between systems. Wireless telephone service providers also must file annual
reports governing equal employment opportunities. Additional requirements are
set forth below:
 
     .  The FCC regulates cellular resale practices and recently extended
        the resale requirement to broadband PCS and ESMR licensees.
        Cellular, PCS and ESMR providers may not restrict any customers'
        resale of their services or unreasonably discriminate against
        resellers of their services. Under present FCC policy, all resale
        obligations for cellular, broadband PCS and ESMR operators will
        terminate on November 24, 2002.
 
                                       99
<PAGE>
 
     .  The FCC has adopted requirements for cellular and other providers
        of two-way voice services to implement basic and enhanced 911
        services ("E-911"), providing emergency service providers with the
        ability to better locate callers that have used wireless phones to
        access 911 features. Implementation of the FCC's E-911
        requirements began in December 1997 and will continue in stages
        until October 2001. These requirements may create additional
        capital obligations for the Company if it is necessary to make
        system changes in order to comply.
 
     .  The Communications Assistance for Law Enforcement Act ("CALEA")
        requires all telecommunications carriers, including cellular,
        paging, and broadband PCS carriers, to modify and design their
        equipment, facilities and services to ensure that authorized law
        enforcement electronic surveillance ("wiretaps") can be performed.
        Specifically, carriers must (1) provide wiretap capabilities in
        the quantities which the FBI specifies in particular geographic
        areas; and (2) ensure that their equipment and services conform
        with CALEA-compliant technical standards and provide law
        enforcement with particular wiretap capabilities. Cellular and PCS
        carriers are required to provide law enforcement agencies with
        technical capabilities for wiretaps by June 30, 2000 and with
        capacity by March 12, 2001.
 
     .  The FCC has adopted telephone number portability rules for local
        exchange carriers ("LECs"), as well as cellular, broadband PCS and
        ESMR licensees, that could facilitate the development of local
        exchange competition, including wireless local loop service. The
        new number portability rules generally require cellular, broadband
        PCS and ESMR licensees to have the capability to deliver calls
        from their systems to ported numbers by December 31, 1998, to
        provide financial support for number portability costs that it
        shares with other carriers and to offer service provider number
        portability and roaming to ported numbers by March 31, 2000.
 
     .  Under current FCC rules, LECs are required to compensate cellular
        and PCS providers for the reasonable costs incurred by such
        providers in terminating traffic that originates on LEC
        facilities, and vice versa. Consistent with this ruling, the FCC
        has determined that LECs may not charge a cellular and PCS
        provider or other carrier for terminating LEC-originated traffic.
        Nor may LECs charge cellular and PCS providers for number
        activation and use fees. These interconnection issues are still in
        dispute, and it is unclear whether the FCC will maintain its
        current position.
 
     .  The FCC attempts to recover the costs of its enforcement, policy
        and rulemaking, international and user information activities by
        collecting "regulatory fees" from every FCC licensee on an annual
        basis. Each year, the FCC estimates what its costs might be and
        publishes a proposed Fee Schedule, setting forth the specific
        amounts it plans to collect from each type of FCC licensee.
        Generally, CMRS regulatory fees are based on units in service as
        of December 31st of the prior calendar year. Every year since it
        began collecting regulatory fees, the FCC has increased the amount
        per unit collected from CMRS licensees.
 
     .  The FCC has adopted new rules regarding payments by
        telecommunications companies into a revamped fund that will
        provide for the widespread availability of telecommunications
        services, including to low-income consumers ("Universal Service").
        Prior to the implementation of the Telecom Act, Universal Service
        obligations largely were met by local telephone companies,
        supplemented by long-distance telephone companies. Under the new
        rules, all telecommunications carriers, including cellular and PCS
        companies, are required to contribute to Universal Service Fund
        (the "Universal Service Fund"). In addition, certain state
        regulatory authorities have enacted, or have indicated that they
        intent to enact, similar contribution requirements based on state
        revenues. Payments into the Universal Service Fund will likely
        increase the cost of doing business. The FCC is currently
        considering whether to establish rules which clarify cellular and
        PCS carriers' federal and state universal service contribution
        requirements.
 
 
                                      100
<PAGE>
 
     .  The FCC has adopted rules to implement the Telecom Act provisions
        for customer proprietary network information (CPNI), including
        electronic computerized safeguards that may impose additional
        costs on the Company. These rules apply to all telecommunications
        carriers, including cellular, PCS and CLECs.
 
      The Company cannot accurately estimate the economic impact of each of
these requirements, which may necessitate system changes, which in turn may
require additional capital expenditures by the Company.
 
      As a wireless telephone service provider, the Company also must
contribute to the Telecommunications Relay Services ("TRS") Fund, which
compensates TRS providers for making service available to the hearing
impaired. The Company also must contribute to support numbering administration
and number portability administration.
 
State and Local Regulation
 
      The Communications Act preempts state or local regulation of the entry
of, or rates charged by, wireless telephone service providers. As a result,
the Company may set rates and offer new products and services without state
regulatory intervention. Nonetheless, state regulatory authority covers such
matters as the terms and conditions of interconnection between local exchange
carriers and wireless carriers with respect to intrastate services, and state
universal service programs. In addition, some states and localities still
exert jurisdiction over (i) zoning and building permits associated with the
construction of antenna towers; (ii) approval of acquisitions and transfers of
wireless systems; and (iii) resolving consumer complaints.
 
      The Company's wireless telephone systems rely on the availability of
antenna towers. The location and construction of such towers are subject to
regulation at the federal, state, and local level. In addition to FCC
regulation, towers are subject to environmental, zoning and land use, and
Federal Aviation Administration regulation. The Communications Act prohibits,
however, states and localities from unreasonably restricting the construction
of antenna towers associated with wireless telephone systems. For example,
localities cannot deny zoning approval for a proposed antenna tower based on
concerns related to radiofrequency ("RF") emissions, if the tower complies
with the Commission's RF rules. Disputes over zoning regulation are generally
subject to state and federal court jurisdiction, and carriers have met with
varying degrees of success in court.
 
      In Puerto Rico, we are also subject to regulation by the Puerto Rico
Planning Board, the Administration of Regulation and Permits and the Puerto
Rico Telecommunications Regulatory Board. These entities' powers include a
number of matters, such as cost-based rate-making that could have a material
adverse effect on our business, financial condition and results of operations.
 
Wireline CLEC Regulation
 
      Lambda CLEC is subject to the Puerto Rico Telecommunications Act of 1996
(the "Puerto Rico Act") which grants jurisdiction over telecommunications
services and providers to the Puerto Rico Telecommunications Regulatory Board
and purports to open the Puerto Rico telecommunications market to competition.
 
      In addition, Lambda CLEC is subject to the Communications Act. Pursuant
to the Communications Act, the FCC requires all telecommunications carriers,
including Lambda CLEC, to contribute to the federal universal service fund.
The Communications Act also requires state public utilities commissions and/or
the FCC to implement policies that mandate reciprocal compensation between
local exchange carriers. On August 1, 1996, the FCC adopted rules implementing
these policies, but various aspects of the Order have been overturned by a
federal court and the decision remains subject to further judicial review.
 
 
                                      101
<PAGE>
 
Relocation of Fixed Microwave Licenses
 
      In an effort to balance the competing interests of incumbent 2 GHz
microwave licensees and new emerging technology licensees (such as PCS
licensees) operating in the 2 GHz band, the FCC adopted a transition plan to
provide for the relocation of incumbent 2 GHz microwave licensees to different
frequencies. For a period of up to five years after the grant of a PCS license,
a PCS licensee may be required to accommodate existing licensees that operate
certain fixed microwave systems within its license area. During this period,
licensees engage in negotiations to set forth the parameters and costs of
relocation. If a PCS licensee provides sufficient incentives for an incumbent
microwave licensee, the incumbent may locate before the expiration of the five-
year period. If no relocation agreement is reached, an incumbent microwave
licensee can be forced to involuntarily relocate.
 
      Relocation generally involves a PCS operator compensating a microwave
incumbent for the costs associated with the aforementioned relocation, and may
include potential "premium" payments provided to the incumbent for relocating
early. Some of these costs are shared among all PCS licensees that benefit from
the relocation pursuant to an FCC mandated cost-sharing formula. Accordingly,
microwave relocation may increase the cost of completing and maintaining
Centennial de Puerto Rico's PCS network. The Company cannot accurately estimate
the degree to which it may be required to relocate 2 GHz microwave links or
anticipate the costs of such relocation.
 
Future Regulation
 
      From time to time, legislation that potentially could affect the Company,
either beneficially or adversely, is proposed by federal or state legislators.
There can be no assurance that such legislation will not be enacted, or that
regulations will not be adopted or actions taken by the FCC or state regulatory
authorities that might adversely affect the business of the Company. For
example, the allocation by the FCC of additional radio spectrum for the
provision of cellular or PCS-like services could adversely affect the Company's
operating results, and the imposition of additional or higher fees on the
provision of the Company's services could adversely impact the Company's
profitability.
 
      The Company has filed a Petition for Declaratory Ruling and Preemption
with the FCC in which it seeks a ruling that the regulatory approach as well as
certain provisions of the Puerto Rico Act are preempted pursuant to Sections
253(a) and 332(c) of the Communications Act because they are inconsistent with
the pro-competition language and/or objectives of the Telecom Act, constitute
impermissible barriers to the entry of local telecommunications competition
and/or constitute impermissible regulation of CMRS entry or rates. This matter
is currently pending.
 
                                   Employees
 
      The Company had 1,735 employees, including 594 employees in Puerto Rico,
as of November 30, 1998. None of the Company's employees is represented by a
labor organization. The Company considers its relationship with its employees
to be good.
 
                                   Properties
 
      The Company leases office space at 1305 and 1325 Campus Parkway, Neptune,
New Jersey where it has its principal executive offices.
 
      The properties for MTSO and cell sites in the Domestic Wireless Telephone
Systems and the Puerto Rico Systems are either owned (approximately 9%) or
leased (approximately 91%), typically under short-term
 
                                      102
<PAGE>
 
leases, by the Company or one of its subsidiaries or the partnership, joint
venture or corporation which holds the construction permit or license (in the
case of the Domestic Wireless Telephone Systems in which the Company has a
minority interest).
 
      The Company leases certain space for equipment in Puerto Rico from
Century-ML Cable Corp. ("Century-ML"), a cable television operator that is 50%
owned by Century, pursuant to a 25-year lease entered into in 1997 when Century
was an affiliate of the Company. Further, the Company leases and shares
capacity on the fiber optic cable television facility and network of Century-ML
for the purpose of operating as a CLEC. The Company shares in the cost of
construction, operation and maintenance of the Century-ML fiber network on a
pro rata basis based on the percentage of the number of fibers of the network
used by or reserved for the Company. This contract will remain in effect
following the Merger. The Company believes that the above transactions and
contemplated transactions between it and Century and Century-ML were entered
into on terms no less favorable to the Company than would have been obtainable
at that time in comparable transactions with unaffiliated parties.
 
      The Company considers the properties owned and leased by it to be
suitable and adequate for its business operations.
 
                               Legal Proceedings
 
      On December 26, 1996, the Company, on behalf of its PCS subsidiary, filed
a petition with the Board seeking arbitration of the many unresolved issues in
the negotiation with PRTC for interconnection of the Company's PCS network with
PRTC's landline telephone network. On January 21, 1997, the Company filed a
petition with the Board seeking arbitration of the many unresolved issues in
the negotiation with PRTC for interconnection of the Company's fiber optic
network with PRTC's landline telephone network. The two petitions were
substantially consolidated by the arbitrator and after several sessions with
the arbitrator and PRTC, the Company and its PCS subsidiary successfully
negotiated interconnection agreements with PRTC covering most of the unresolved
issues. Those agreements, which reflect considerably lower interconnection
rates than those PRTC had been charging, have been approved by the Board and
are currently in effect.
 
      On January 9, 1998, Centennial filed a complaint challenging the decision
of Ameritech Corporation Michigan Bell Telephone Co., d/b/a Ameritech Michigan
("Ameritech") to withdraw reverse billing. Reverse billing is an arrangement
that permits a landline telephone customer to place a call to a cellular or
pager customer without paying local or toll charges. Instead, the provider pays
Ameritech an access-like charge. The Michigan Public Service Commission found
that Centennial was not entitled to an order requiring Ameritech to continue to
offer reverse billing because federal and Michigan telecommunications laws
require parties to first negotiate among themselves and then submit to
arbitration, if necessary. If Centennial is unsuccessful in negotiating with
Ameritech or loses an arbitration, Centennial would need to reprogram its
customers' cellular phones to try to align their numbers with the areas where
the customer's land-to-mobile calls mainly originate. None of Centennial's
other interconnection partners has indicated that they are planning to withdraw
reverse billing, but there can be no assurance that reverse billing will
continue or that such reprogramming would not impose significant costs on
Centennial.
 
      There are no other material pending legal proceedings, other than routine
litigation incidental to the business, to which the Company or any of its
subsidiaries is a party to or which any of their property is subject.

Director Compensation
 
      Centennial Cellular Operating. None of the directors of Centennial
Cellular Operating will receive any remuneration from Centennial Cellular
Operating for their attendance at Board and committee meetings during 1999.
 
      Centennial. During the fiscal year ended May 31, 1998, each director who
was not also an employee of the Company received quarterly retainers of $3,000
plus a uniform fee of $750 for each Board and committee meeting attended. In
addition, options for 1,000 shares of Common Shares were automatically granted
under the 1993 Non-Employee/Officer Directors' Stock Option Plan to each person
who was a non-employee/officer director on the date of each annual meeting of
shareholders of the Company. During such period, directors who were also
employees of the Company received no remuneration for attendance at Board and
committee meetings.

an employee of the Company will receive compensation in accordance with the
Equity Investors' customary practices. The Company expects that such
compensation will be consistent with compensation paid to directors in
comparable public companies.

                             PRINCIPAL STOCKHOLDERS
 
      Following the consummation of the Merger and related transactions, all of
the issued and outstanding capital stock of Centennial Cellular Operating is
owned by Centennial. The following table sets forth certain information
regarding the beneficial ownership of Centennial's common stock immediately
following the consummation of the Merger and related transactions by (i) each
stockholder who owns beneficially five percent or more of the Class A Common
Stock, (ii) each director of the Centennial, (iii) each executive officer and
(iv) all directors and officers as a group.
 
      The number of shares beneficially owned by each stockholder, director or
officer is determined according to the rules of the Commission, and the
information is not necessarily indicative of beneficial ownership for any other
purpose. Under such rules, beneficial ownership includes any shares as to which
the individual or entity has sole or shared voting power or investment power.
As a consequence, several persons may be deemed to be the "beneficial owners"
of the same shares. Unless otherwise noted in the footnotes to this table, each
of the stockholders named in this table has sole voting and investment power
with respect to the Class A Common Stock shown as beneficially owned. The
percentage ownership of each stockholder is calculated based on 31,125,579
shares of Class A Common Stock outstanding (after giving effect to a three-for-
one stock split effected on January 8, 1999).

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
Equity Investor Agreements
 
      In connection with their initial investment in Acquisition and the Common
Equity Contribution and simultaneously with the consummation of the Merger, the
Equity Investors and Acquisition entered into a Securities Purchase Agreement,
a Registration Rights Agreement and a Stockholders Agreement.
 
      Pursuant to the Securities Purchase Agreement, the Equity Investors
purchased an aggregate of 9,638,554 shares of Common Stock of Acquisition at
the time of the Merger. The Securities Purchase Agreement contains customary
conditions, representations and warranties, and will terminate upon the
termination of the Merger Agreement.
 
      At the same time, the Equity Investors and the Company entered into a
Stockholders' Agreement pursuant to which they agreed to establish a board of
directors of the Company consisting of nine members. WCAS and certain of its
affiliates (the "WCAS Investors") will designate three of such directors, who
initially are Thomas E. McInerney, Anthony J. de Nicola and Rudolph E. Rupert,
so long as the WCAS Investors own in the aggregate at least 25% of the shares
of the surviving corporation owned by them as of the date of the Merger.
Blackstone and its affiliates (the "Blackstone Investors") will designate two
directors, who initially are Mark T. Gallogly and Lawrence H. Guffey, so long
as the Blackstone Investors own in the aggregate at least 25% of the shares of
the surviving corporation owned by them as of the date of the Merger. The Chief
Executive Officer and the Chief Operating Officer of the Company, who initially
are Michael J. Small and Rudy Graf, respectively, will also be directors. The
remaining two directors will be outside directors nominated by the board of
directors and elected by stockholders of the Company, including the Equity
Investors. Pursuant to the Stockholders Agreement, the Equity Investors (other
than the WCAS Investors) also have "tag-along" rights to participate in certain
proposed dispositions of the Company's shares by the WCAS Investors. In
addition, in the event that the WCAS Investors or the Company receives a third
party offer to purchase at least 80% of the outstanding capital stock of the
Company, a majority of the WCAS Investors may require the other Equity
Investors to accept such offer and to sell their shares of the Company to such
third party. The Company has also granted the Equity Investors pre-emptive
rights with respect to participating, on a pro rata basis according to their
stock ownership, in certain eligible offerings (excluding registered public
offerings of Common Shares and offerings of Common Shares or options to
purchase Common Shares in connection with certain stock option plans or stock
purchase plans). While the Stockholders Agreement is in effect, the Company may
not amend, alter or repeal its organizational documents without obtaining the
consent of a majority in interest of the WCAS Investors and the Blackstone
Investors, as well as a majority of the other Equity Investors adversely
affected by such amendment or alteration. Further, the Stockholders Agreement
contains certain restrictions on transactions with related persons. Upon the
consummation of the Merger and related transactions, an affiliate of each of
WCAS and Blackstone received a deal consummation fee of $10.6 million and $3.4
million, respectively. An Equity Investor unaffiliated with Blackstone and WCAS
received a fee of $4.0 million upon the consummation of the Merger. During the
term of the Stockholders' Agreement, an affiliate of each of WCAS and
Blackstone shall receive an annual monitoring fee of $450,000 and $300,000,
respectively.
 
      Pursuant to the Registration Rights Agreement entered into among the
Company and the Equity Investors, the WCAS Investors and the Blackstone
Investors have certain rights to require the Company to register their shares
of the Company under the Securities Act and to include, upon request, their
shares in any registration of shares effected by the Company.
 
Former Indebtedness of Certain Executive Officers
 
      During fiscal 1998, Thomas R. Cogar, Vice President of Engineering of
Centennial received a relocation loan from the Company of approximately $65,000
and John H. Casey, Vice President--
 
                                      112
<PAGE>
 
Administration of Centennial received a relocation and temporary house loan of
approximately $200,000. There are no amounts outstanding under these loans.
 
Arrangements with Former Controlling Stockholder
 
      Pursuant to the Stockholder Agreement, on the effective date of the
Merger, Century executed and delivered a non-compete agreement with Centennial,
pursuant to which Century agreed that, for a period of three years from the
effective date, it will not engage in, or acquire a controlling interest in,
any business that competes with any of the businesses of the Company's current
operations in Puerto Rico; provided, however, that such non-compete shall not
extend to or restrict in any manner the activities of Century's existing joint
venture in Puerto Rico, Century M-L.
 
      The Company and Century, which owned a controlling interest in Centennial
prior to the Merger, previously maintained combined workers compensation and
general insurance policies. The premiums were allocated between the Company and
Century based upon the actual cost of each respective company's coverage. The
Company believes that the amounts payable by the Company under such arrangement
were more favorable than the premiums the Company would have paid if it had
obtained coverage under a separate policy. The Company's cost of such insurance
was approximately $0.6 million, $0.7 million and $1.7 million for the fiscal
years ended May 31, 1998, 1997 and 1996, respectively, all of which was paid in
full during the current fiscal year. In fiscal 1996, the Company and Century
also maintained combined group health, life and casualty coverage. Pursuant to
the Merger Agreement, the Company has covenanted to maintain for a period of at
least two years employee benefits and incentive compensation that are no less
favorable to the employees.
 
      The Company and Century entered into a Services Agreement, effective
August 30, 1996 (the "Services Agreement"), pursuant to which Century, through
its personnel, provides design, construction, management, operational,
technical and maintenance for the wireless telephone, paging and related
systems owned and operated by the Company. Such services also include providing
all the services necessary for the monitoring, to the extent possible, of the
activities of the partnerships in which the Company has minority equity
interests, in such manner as to protect the interests of the Company. Such
services have historically been provided to the Company by Century. As
consideration for the services rendered under the Services Agreement, the
Company paid Century the annual sum of $1.0 million and reimbursed Century for
all costs incurred by Century or its affiliates (excluding the Company and its
subsidiaries) that were directly attributable to the design, construction,
management, operation and maintenance of the wireless telephone, paging and
related systems of the Company or to the performance by Century of its other
duties under the Services Agreement. For the years ended May 31, 1998 and 1997,
the Company recorded expenses of $1.0 million and $0.8 million, respectively,
under the Services Agreement. At May 31, 1998 and 1997, $0.3 million and $0.8
million, respectively, of such amounts were recorded within Payable to
Affiliate on the Company's consolidated balance sheet. As of the effective time
of the Merger, Century and Centennial terminated the Services Agreement.
 
      The Company leases space for the MTSO serving the southwestern cluster
and space on an antenna tower in the southwestern cluster from Century for an
aggregate current annual rent of approximately $1,000 pursuant to an oral
month-to-month lease agreement. Further, the Company leases certain warehouse
space in Puerto Rico to Century-ML for a current annual rent of approximately
$23,000 pursuant to a written lease agreement. The Company leases and shares
capacity on the fiber optic cable television facility and network of Century-ML
fiber network for the purposes of operating as a competitive access provider.
The Company shares the cost of construction, operation and maintenance of the
Century-ML fiber network on a pro rata basis based on the percentage of the
number of fibers of the network used by or reserved for the Company.
 
      During fiscal 1997, the Company recorded a deferred asset and related
payable to an affiliate in its consolidated balance sheet in the amount of $6.0
million to reflect certain costs incurred by the Company to secure the use of
the fiber optic network as required by the Facilities Agreement. This amount,
which was paid
 
                                      113
<PAGE>
 
by the Company during fiscal 1998, represents the Company's share of the costs
of constructing Century-ML's fiber optic network.
 
      Leavy Rosensweig & Hyman, of which David Z. Rosensweig, a director and
Secretary of the Company prior to the Merger, is a member, provides legal
services to the Company.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
The Credit Facility
 
      In connection with the Merger, Centennial and certain of its subsidiaries
entered into the Credit Facility with Merrill Lynch Capital Corporation
("Merrill Lynch Capital"), NationsBank, N.A. ("NationsBank"), The Chase
Manhattan Bank ("Chase"), The Bank of Nova Scotia ("Scotia") and Morgan Stanley
Senior Funding, Inc. ("Morgan Stanley" and collectively with Merrill Lynch
Capital, NationsBank, Chase and Scotia, the "Agents") and certain other
financial institutions (collectively, with the Agents, the "Lenders"), pursuant
to which the Lenders provided credit facilities to certain of Centennial's
subsidiaries. The following is a summary of the proposed terms and conditions
of each Credit Facility.
 
      The Borrowers. The borrowers under the Credit Facility are Centennial
Cellular Operating Co. LLC ("Centennial Cellular Operating"), a wholly-owned
direct subsidiary of Centennial, and Centennial de Puerto Rico, a wholly-owned
direct subsidiary of Centennial Cellular Operating (the "PR Borrower").
 
      The Facility. The Credit Facility provides for a senior secured revolving
credit facility (the "Revolving Credit Facility"), which provides revolving
loans (the "Revolving Credit Loans") in an aggregate principal amount of up to
the Lenders' revolving credit commitment (the "Revolving Credit Commitment"),
which will initially be $150 million (of which a sublimit thereof will be
available to be borrowed by PR Borrower), and senior secured term loan
facilities in four tranches (the "Term Loan Facilities"), which provide term
loans (the "Term Loans") in an aggregate principal amount of up to $900 million
(of which one tranche thereof is available to be drawn by PR Borrower).
 
      Use of Credit Facility Proceeds. The proceeds of the Credit Facility were
used, together with other proceeds of the Merger Financings, to fund payment of
cash consideration in the Merger, repay Centennial's indebtedness (including
the purchase of the Tendered Notes in the Debt Tender Offers), pay the related
fees and expenses and purchase the Pledged Securities. In addition, the
Revolving Credit Facility is available after the closing thereof subject to the
conditions set forth in the Credit Facility documentation to finance future
working capital needs, capital expenditures, permitted acquisitions, and for
general corporate purposes.
 
      Under certain circumstances, the Credit Facility may be increased by up
to $150 million in aggregate principal amount, upon terms and conditions no
more onerous than those contained in the Credit Facility.
 
      Availability of Loans. The Term Loans was available on the date of
closing of the Merger (the "Effective Date"). The Revolving Credit Loans were
available on the Effective Date in a principal amount not to exceed $65 million
and thereafter on a revolving basis until 30 days prior to the maturity
thereof. Up to $25 million of the Revolving Credit Facility is available for
the issuance of letters of credit and up to $30 million of the Revolving Credit
Facility will be available for swing loans.
 
      Maturity of Loans. The Revolving Credit Commitments will be reduced
quarterly beginning in the fourth year after the closing of the Credit Facility
(the "Closing Date") and the Revolving Credit Facility will mature eight years
after the Closing Date. The Term Loans will consist of four tranches and will
amortize over eight years for tranche A Term Loans ("Tranche A Loans"), eight
years for tranche A-PR Term Loans ("Tranche A-PR Loans"), eight and one-half
years for tranche B Term Loans (the "Tranche B Loans") and nine years for
tranche C Term Loans (the "Tranche C Loans").
 
      Prepayments. Borrowings and commitments under the Credit Facility are
subject to mandatory prepayment and reduction in an amount equal to (a) 100% of
the net proceeds of asset dispositions (including insurance proceeds resulting
from casualty to assets), subject to the borrower's ability to reinvest such
proceeds under certain circumstances, (b) 75% of excess cash flow (reduced to
50% with respect to any fiscal year if the Total Leverage Ratio (defined as the
ratio of total debt to operating cash flow) is less than 6.0:1.0), (c) 100% of
 
                                      115
<PAGE>
 
the net proceeds of the issuance or incurrence of debt or of any sale and
lease-back, and (d) 50% of the net proceeds of any issuance of equity
securities. Voluntary prepayment of the loans will be permitted in whole or in
part with prior notice. The Revolving Credit Loans and the Tranche A and
Tranche A-PR Loans are subject to prepayment without premium or penalty (other
than funding losses), subject to limitations as to minimum amounts. The Tranche
B and Tranche C Loans are subject to prepayment (x) on or prior to the first
anniversary of the Closing Date, with a premium of 2% of the aggregate
principal amount of loans prepaid, (y) after the first anniversary of the
Closing Date and on or prior to the second anniversary of the Closing Date,
with a premium of 1% of the aggregate principal amount of loans prepaid and (z)
thereafter, without premium or penalty (other than funding losses), subject to
limitations as to minimum amounts.
 
      Interest Rates. Borrowings under the Credit Facility bear interest at a
rate per annum of, at the borrowers' option, either (a) a base rate (defined as
the higher of (i) the announced prime rate of NationsBank, and (ii) the federal
funds rate, plus 0.50%) plus the Applicable Margin (as defined) or (b) a LIBOR
rate plus the Applicable Margin. The maximum Applicable Margin for the Tranche
A Loans, Tranche A-PR Loans and the Revolving Credit Loans is 2.00% for base
rate loans and 3.00% for LIBOR loans, for the Tranche B Loans will be 2.50% for
base rate loans and 3.50% for LIBOR loans, and for the Tranche C Loans will be
2.75% for base rate loans and 3.75% for LIBOR loans. Based upon Centennial
Cellular Operating's leverage ratio after the delivery of certain financial
statements after the Closing Date, the Applicable Margin for Tranche A Loans,
Tranche A-PR Loans and Revolving Credit Loans may be reduced by up to 1.250%
for base rate loans and LIBOR loans. The default rate under the Credit Facility
is 2.00% above the otherwise applicable rate.
 
      Fees and Expenses. The Credit Facility requires the borrower to pay (a)
commitment fees to the Lenders in an amount equal to 0.50% or 0.375% per annum
on the unused commitment under the Revolving Credit Facility, depending on
Centennial Cellular Operating's leverage ratio, and (b) an annual
administrative agent's fee. Additionally, the borrowers paid various fees and
costs in connection with the Credit Facility, including commitment fees and
underwriting fees to Merrill Lynch Capital, NationsBank, Chase, Scotia, and
Morgan Stanley.
 
      Guarantees. Centennial and each of Centennial Cellular Operating's direct
and indirect existing and future subsidiaries (other than foreign subsidiaries)
will be required to guarantee Centennial Cellular Operating's obligations under
the Credit Facility, and Centennial Cellular Operating and PR Borrower's direct
and indirect existing and future subsidiaries were required to guarantee PR
Borrower's obligations under the Credit Facility.
 
      Security. The obligations of Centennial Cellular Operating under the
Credit Facility are secured by substantially all of the assets of Centennial
and each of its direct and indirect existing and future subsidiaries (other
than foreign subsidiaries), including the capital stock of such subsidiaries,
and the obligations of PR Borrower under the Credit Facility are secured by
substantially all of the assets of PR Borrower and each of its direct and
indirect existing and future subsidiaries, including the capital stock of such
subsidiaries.
 
      In addition, Centennial guaranteed the Credit Facility and pledged as
security for Centennial Cellular Operating's obligations the capital stock of
Centennial Cellular Operating to the Lenders under the Credit Facility. The
pledge of such capital stock of Centennial Cellular Operating could impair
Centennial Cellular Operating's ability to obtain future financing on favorable
terms, if at all. Further, in the event Centennial Cellular Operating were to
default on its obligations under the Credit Facility and the Lenders were to
foreclose upon such pledged capital stock of Centennial Cellular Operating,
Centennial, as the holding company of Centennial Cellular Operating, would
likely be unable to service or repay its indebtedness, including the Notes.
 
      Conditions. Various conditions precedent to borrowings under the Credit
Facility on the Effective Date were satisfied.
 
 
                                      116
<PAGE>
 
      Representations and Warranties. The Credit Facility will contain
representations and warranties customarily found in loan agreements for similar
financings.
 
      Affirmative Covenants. The Credit Facility contains affirmative covenants
customarily found in loan agreements for similar financings. Centennial
Cellular Operating is required to enter into interest rate hedging agreements
with respect to 50% of the indebtedness under the Credit Facility for a period
of time satisfactory to the Lenders.
 
      Negative Covenants. The Credit Facility contains customary restrictive
covenants, including covenants that limit (subject to certain exceptions) the
ability of the Centennial Cellular Operating and its subsidiaries to: (a) incur
indebtedness or contingent obligations, issue guarantees or enter into
operating leases; (b) grant liens or negative pledges; (c) make investments or
enter into joint ventures; (d) make certain restricted payments; (e) make
fundamental changes in their business, corporate structure or capital
structure; (f) sell assets or receivables; (g) make capital expenditures; (h)
enter into transactions with affiliates; (i) amend documents relating to other
existing indebtedness and other material documents; or (j) prepay other
indebtedness.
 
      Financial Covenants. The Credit Facility contains financial covenants
relating to: (a) minimum interest coverage ratio; (b) minimum fixed charge
coverage ratio; (c) maximum ratio of total debt to operating cash flow; (d)
maximum ratio of senior debt to operating cash flow; (e) minimum pro forma debt
service coverage ratio; and (f) limitation on capital expenditures.
 
      Events of Default. The Credit Facility includes standard events of
default, including, subject to certain exceptions, those related to (i) default
in the payment of principal and interest, (ii) cross-default in payment of
other indebtedness of more than $10.0 million, (iii) materially incorrect
representations and warranties, (iv) default in the observance or performance
of any of the affirmative or negative covenants included in the Credit Facility
documentation or in the related security and pledge documents, (v) the failure
to or admission in writing of an inability to pay debts when such debts become
due, (vi) certain events of bankruptcy, (vii) certain judgments or decrees
involving more than $10.0 million, (viii) certain ERISA events, (ix) a Change
of Control (as defined in the Credit Facility), (x) the failure of the
applicable Credit Facility documents or any material provision thereof, the
guarantees, security documents or any related documents to be in full force and
effect, (xi) certain non-monetary judgments or decrees which might have a
material effect, (xii) the termination, revocation or nonrenewal of one or more
cellular licenses if such termination, revocation or nonrenewal will have a
material effect, and (xiii) the failure of the Merger to be consummated
substantially concurrent with the extension of credit under the Credit
Facilities.
 
Subordinated Debt
 
      As part of the Mezzanine Financing, WCAS Capital Partners III, L.P., an
investment partnership affiliated with WCAS, purchased at the time of the
consummation of the Merger, a Senior Subordinated Note of Centennial due 2009
(the "Senior Subordinated Note") in the original principal amount of $180
million, as well as an agreed upon number of shares of Common Stock of
Centennial, for an aggregate cash purchase price of $180 million. The Senior
Subordinated Note bears cash interest at a rate of 10% or pay-in-kind interest
at a rate of 13% per annum. Centennial Cellular Operating is restricted from
making cash payments to Centennial to service the debt under certain
circumstances under the Notes and the Credit Facility. See "Description of the
New Notes--Certain Covenants--Limitation on Restricted Payments."
 
      The Senior Subordinated Note is prepayable at Centennial's option and
must (subject to the terms of the Indenture and the Credit Facility) be prepaid
in the event of a "Change in Control," defined as (i) the acquisition by a
person or group acting together (other than the Equity Investors and their
affiliates) of either at least 50% of the voting stock of Centennial or
sufficient voting power to elect a majority of the Board of Directors, (ii) a
merger or consolidation of Centennial as a result of which the stockholders of
Centennial do
 
                                      117
<PAGE>
 
not continue to hold a majority of the voting capital stock of the resulting
entity or (iii) the sale by Centennial of substantially all of its assets.
 
      The Senior Subordinated Note contains certain affirmative and negative
covenants typically found in subordinated notes. The Senior Subordinated Note
may not be transferred without the consent of the Lenders under the Credit
Facility or, during the period ending 180 days after the closing of the
Offering of the Notes, without the consent of Merrill Lynch on behalf of the
Initial Purchasers.
 
      The Senior Subordinated Note is subordinate in right of payment to the
Notes to the extent set forth in the Senior Subordinated Note. Under the Senior
Subordinated Note, Centennial may not make any payments thereon if there is a
default under any "Senior Indebtedness" which is defined to include the Notes.
If an "Event of Default" occurs under the Senior Subordinated Note (except in
connection with certain bankruptcy events), the holder of the Senior
Subordinated Note may not accelerate such debt unless the indebtedness under
the Notes and the Credit Facility have been accelerated for at least 90 days.
The Senior Subordinated Note is also subordinate to the Credit Facility to the
same extent.
 
                                      118
<PAGE>
 
                          DESCRIPTION OF THE NEW NOTES
 
General
 
      The New Notes will be issued under the Indenture, dated as of December
14, 1998 (as amended, the "Indenture"), among Centennial Cellular Operating Co.
LLC, as the Issuer, Centennial Cellular Corp., as successor to Centennial
Finance Corp., as a co-obligor, and The Chase Manhattan Bank, as trustee (the
"Trustee"), a copy of which will be made available to holders of Old Notes upon
request. For purposes of this section, the term "Issuer" means Centennial
Cellular Operating Co. LLC without its subsidiaries and the term "Centennial"
means Centennial Cellular Corp. without its subsidiaries. For purposes of this
section, the term "Co-Obligors" means the Issuer and Centennial, in each case
without their respective subsidiaries.
 
      The terms of the New Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of
1939 (the "Trust Indenture Act"). The New Notes are subject to all such terms,
and prospective holders of New Notes are referred to the Indenture and the
Trust Indenture Act for a statement thereof. The following summary of certain
provisions of the Indenture and the Pledge and Escrow Agreement does not
purport to be complete and is qualified in its entirety by reference to the
Indenture and the Pledge and Escrow Agreement, including the definitions
therein of certain terms used below. Copies of the Indenture and Pledge and
Escrow Agreement are available from the Issuer upon request. The definitions of
certain terms used in the following summary are set forth below under the
caption "--Certain Definitions."
 
      The New Notes will be senior subordinated obligations of the Co-Obligors
limited to $370 million aggregate principal amount. The New Notes will be
issued at par. The New Notes will mature on December 15, 2008. The New Notes
will bear interest at the rate per annum stated on the cover page hereof from
December 14, 1998 or from the most recent Interest Payment Date to which
interest has been paid or provided for, payable semi-annually in arrears on
June 15 and December 15 of each year (each, an "Interest Payment Date"),
commencing June 15, 1999 to the Persons in whose names such New Notes are
registered at the close of business on June 1 or December 1 preceding such
Interest Payment Date. Interest on the New Notes will accrue from the most
recent Interest Payment Date to which interest has been paid or duly provided
for on the Old Note surrendered in exchange for such New Note, or, if no
interest has been paid or duly provided for on such Old Note, from December 14,
1998. Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months. The New Notes will be issued only in fully registered
form, without coupons, in denominations of $1,000 and integral multiples
thereof.
 
      The Indenture does not contain provisions which would afford Holders of
the New Notes protection in the event of a decline in the Co-Obligors' credit
quality resulting from highly leveraged or other similar transactions involving
the Co-Obligors.
 
      Principal of, premium, if any, and interest on the New Notes will be
payable, and, subject to the following provisions, the New Notes may be
presented for registration of transfer or exchange, at the office or agency of
the Co-Obligors maintained for such purpose, which office or agency shall be
maintained in the Borough of Manhattan of The City of New York. At the option
of the Co-Obligors, payment of interest may be made by check mailed to the
Holders of the New Notes at the addresses set forth upon the registry books of
the Co-Obligors. No service charge will be made for any registration of
transfer or exchange of New Notes, but the Co-Obligors may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith. Until otherwise designated by the Co-Obligors, the Co-
Obligors' office or agency will be the corporate trust office of the Trustee
presently located in New York, New York.
 
      Settlement for the New Notes will be made in same day funds. All payments
of principal and interest will be made by the Co-Obligors in same day funds.
The New Notes will trade in the Same-Day Funds Settlement System of The
Depository Trust Company (the "Depositary" or "DTC") until maturity, and
secondary market trading activity for the New Notes will therefore settle in
same day funds.
 
                                      119
<PAGE>
 
      When issued, the New Notes will be a new issue of securities with no
established trading market. No assurance can be given as to the liquidity of
the trading market for the Notes. See "Risk Factors--Absence of Public Trading
Market for the New Notes."
 
Ranking
 
      The payment of the principal of, premium, if any, and interest on, the
New Notes will be subordinated, as set forth in the Indenture, in right of
payment, to the prior payment in full of all Senior Indebtedness. The New Notes
will be senior subordinated indebtedness of the Issuer ranking pari passu with
all other existing and future senior subordinated indebtedness of the Issuer
and senior to all existing and future Subordinated Indebtedness of the Issuer.
 
      In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding
in connection therewith, relating to the Issuer or to its assets, or any
liquidation, dissolution or other winding-up of the Issuer, whether voluntary
or involuntary and whether or not involving insolvency or bankruptcy, or any
assignment for the benefit of creditors or their marshalling of assets or
liabilities of the Issuer (except in connection with the consolidation or
merger of the Issuer or its liquidation or dissolution following the
conveyance, transfer or lease of its properties and assets substantially as an
entirety upon the terms and conditions described under "Certain Covenants--
Limitation on Merger, Sale or Consolidation" below), the holders of Senior
Indebtedness will be entitled to receive payment in full in cash or cash
equivalents of all Senior Indebtedness, or provision shall be made for such
payment in full, before the holders of New Notes will be entitled to receive
any payment or distribution of any kind or character (other than any payment or
distribution in the form of equity securities or subordinated securities of the
Issuer or any successor obligor that, in the case of any such subordinated
securities, are subordinated in right of payment to all Senior Indebtedness
that may at the time be outstanding to at least the same extent as the New
Notes are so subordinated (such equity securities or subordinated securities
hereinafter being "Permitted Junior Securities") and any payment made pursuant
to the provisions described under "--Legal Defeasance and Covenant Defeasance"
from monies or U.S. Government Obligations (as defined in the Indenture)
previously deposited with the Trustee on account of principal of, or premium,
if any, or interest on the New Notes); and any payment or distribution of
assets of the Issuer of any kind or character, whether in cash, property or
securities (other than a payment or distribution in the form of Permitted
Junior Securities and payments made pursuant to the provision described under
"--Legal Defeasance and Covenant Defeasance" from monies or U.S. Government
Obligations previously deposited with the Trustee), by set-off or otherwise, to
which the holders of the New Notes or the Trustee would be entitled but for the
provisions of the Indenture shall be paid by the liquidating trustee or agent
or other person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Senior Indebtedness or their representative or representatives
ratably according to the aggregate amounts remaining unpaid on account of the
Senior Indebtedness to the extent necessary to make payment in full of all
Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution to the holders of such Senior Indebtedness.
 
      No payment or distribution of any assets of the Issuer of any kind or
character, whether in cash, property or securities (other than Permitted Junior
Securities and payments made pursuant to the provisions described under "--
Legal Defeasance and Covenant Defeasance" from monies or U.S. Government
Obligations previously deposited with the Trustee), may be made by or on behalf
of the Issuer on account of principal of, premium, if any, or interest on the
Notes or on account of the purchase, redemption or other acquisition of New
Notes upon the occurrence of any default in payment (whether at stated
maturity, upon scheduled installment, by acceleration or otherwise) of
principal of, premium, if any, or interest on Designated Senior Indebtedness
(as defined below) (a "Payment Default") until such Payment Default shall have
been cured or waived in writing or shall have ceased to exist or such
Designated Senior Indebtedness shall have been discharged or paid in full in
cash or cash equivalents.
 
 
                                      120

      No payment or distribution of any assets of the Issuer of any kind or
character, whether in cash, property or securities (other than Permitted Junior
Securities and payments made pursuant to the provisions described under "--
Legal Defeasance and Covenant Defeasance" from monies or U.S. Government
Obligations previously deposited with the Trustee), may be made by or on behalf
of the Issuer on account of principal of, premium, if any, or interest on the
New Notes or on account of the purchase, redemption or other acquisition of New
Notes for the period specified below (a "Payment Blockage Period") upon the
occurrence of any default or event of default with respect to any Designated
Senior Indebtedness other than any Payment Default pursuant to which the
maturity thereof may be accelerated (a "Non-Payment Default") and receipt by
the Trustee of written notice thereof from the agent bank under the Credit
Facility (the "Agent Bank") or other representative of holders of Designated
Senior Indebtedness.
 
      The Payment Blockage Period will commence upon the date of receipt by the
Trustee of written notice from the Agent Bank or such other representative of
the holders of the Designated Senior Indebtedness in respect of which the Non-
Payment Default exists and shall end on the earliest of (i) 179 days thereafter
(provided that any Designated Senior Indebtedness as to which notice was given
shall not theretofore have been accelerated), (ii) the date on which such Non-
Payment Default is cured, waived or ceases to exist or such Designated Senior
Indebtedness is discharged or paid in full in cash or cash equivalents or (iii)
the date on which such Payment Blockage Period shall have been terminated by
written notice to the Trustee or the Issuer from the Agent Bank or such other
representative initiating such Payment Blockage Period, after which the Issuer
will resume making any and all required payments in respect of the Notes,
including any missed payments. In any event, not more than one Payment Blockage
Period may be commenced during any period of 365 consecutive days, and there
must be at least 186 consecutive days in every 365 day period during which
there is no Payment Blockage Period. No event of default that existed or was
continuing on the date of the commencement of any Payment Blockage Period will
be, or can be made, the basis for the commencement of a subsequent Payment
Blockage Period, unless such default has been cured or waived for a period of
not less than 90 consecutive days subsequent to the commencement of such
initial Payment Blockage Period.
 
      In the event that, notwithstanding the provisions of the preceding four
paragraphs, any payment shall be made to the Trustee which is prohibited by
such provisions, then and in such event such payment shall be paid over and
delivered by such Trustee to the Agent Bank and any other representative of
holders of Designated Senior Indebtedness, as their interests may appear, for
application to Designated Senior Indebtedness. After all Senior Indebtedness is
paid in full and until the New Notes are paid in full, holders of the New Notes
shall be subrogated (equally and ratably with all other Indebtedness pari passu
with the New Notes, including the Old Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the New Notes
have been applied to the payment of Senior Indebtedness.
 
      Failure by the Issuer to make any required payment in respect of the New
Notes when due and within any applicable grace period, whether or not occurring
during a Payment Blockage Period, will result in an Event of Default under the
Indenture and, therefore, holders of the New Notes will have the right to
accelerate the maturity thereof. See "--Events of Default."
 
      By reason of such subordination, in the event of liquidation,
receivership, reorganization or insolvency of the Issuer, creditors of the
Issuer who are holders of Senior Indebtedness may recover more, ratably, than
the holders of the New Notes, and assets which would otherwise be available to
pay obligations in respect of the New Notes will be available only after all
Senior Indebtedness has been paid in full in cash or cash equivalents, and
there may not be sufficient assets remaining to pay amounts due on any or all
of the New Notes.
 
      "Senior Indebtedness" means the principal of, premium, if any, and
interest (including interest, to the extent allowable, accruing after the
filing of a petition initiating any proceeding under any state, federal or
foreign bankruptcy law) on any Indebtedness of the Issuer (other than as
otherwise provided in this definition), whether outstanding on the date of the
Indenture or thereafter created, incurred or assumed, and whether at any
 
                                      121
<PAGE>
 
time owing, actually or contingent, unless, in the case of any particular
Indebtedness, the instrument creating or evidencing the same or pursuant to
which the same is outstanding expressly provides that such Indebtedness shall
not be senior in right of payment to the New Notes. Notwithstanding the
foregoing, "Senior Indebtedness" shall not include (i) Indebtedness evidenced
by the Notes, (ii) Indebtedness that is subordinate or junior in right of
payment to any Indebtedness of the Issuer, (iii) Indebtedness which when
incurred and without respect to any election under Section 1111(b) of Title 11
United States Code, is without recourse to the Issuer, (iv) Indebtedness which
is represented by Disqualified Capital Stock, (v) any liability for foreign,
federal, state, local or other taxes owed or owing by the Issuer to the extent
such liability constitutes Indebtedness, (vi) Indebtedness of the Issuer to a
Subsidiary or any other Affiliate of the Issuer or any of such Affiliate's
Subsidiaries, (vii) to the extent it might constitute Indebtedness, amounts
owing for goods, materials or services purchased in the ordinary course of
business or consisting of trade accounts payable owed or owing by the Issuer,
and amounts owed by the Issuer for compensation to employees or services
rendered to the Issuer, (viii) that portion of any Indebtedness which at the
time of issuance is issued in violation of the Indenture and (ix) Indebtedness
evidenced by any guarantee of any Subordinated Indebtedness or Pari Passu
Indebtedness.
 
      "Designated Senior Indebtedness" means (i) all Senior Indebtedness under
the Credit Facility and (ii) any other Senior Indebtedness which at the time of
determination has an aggregate principal amount outstanding of at least $25
million and which is specifically designated in the instrument evidencing such
Senior Indebtedness or the agreement under which such Senior Indebtedness
arises as "Designated Senior Indebtedness" by the Issuer.
 
      The Indenture will limit, but not prohibit, the incurrence by the Issuer
and its Subsidiaries of additional Indebtedness, and the Indenture will
prohibit the incurrence by the Issuer of Indebtedness that is subordinated in
right of payment to any Senior Indebtedness of the Issuer and senior in right
of payment to the New Notes.
 
      The New Notes will rank junior to all Senior Indebtedness of the Issuer,
equal in right of payment to all future senior subordinated indebtedness of the
Issuer and senior to all Subordinated Indebtedness of the Issuer. As of
November 30, 1998, on a pro forma basis, the Issuer would have had $936.0
million in aggregate principal amount of Senior Indebtedness outstanding and
$370 million in aggregate principal amount of senior Subordinated Indebtedness
representing the Notes. See "Unaudited Pro Forma Financial Information."
 
      The Issuer conducts its operations through its Subsidiaries. Accordingly,
the Issuer's ability to meet its cash obligations is dependent upon the ability
of its Subsidiaries to make cash distributions to the Issuer. Dividends from
the Issuer's Subsidiaries are expected to be the only source for payment of
interest on the New Notes after the first three interest payments (which will
be satisfied from the Pledged Securities). Furthermore, any right of the Issuer
to receive the assets of any of its Subsidiaries upon any such Subsidiary's
liquidation (and the consequent right of the Holders of the New Notes to
participate in the distribution of the proceeds of those assets) effectively
will be subordinated by operation of law to the claims of such Subsidiary's
creditors (including trade creditors) and holders of its preferred stock, if
any, except to the extent that the Issuer is itself recognized as a creditor or
preferred stockholder of such Subsidiary, in which case the claims of the
Issuer would still be subordinate to any Indebtedness or preferred stock of
such Subsidiary senior in right of payment to that held by the Issuer. In the
event of the liquidation, bankruptcy, reorganization, insolvency, receivership
or similar proceeding or any assignment for the benefit of the creditors of the
Issuer or a marshaling of assets or liabilities of the Issuer, Holders of the
New Notes may receive ratably less than other such creditors or interest
holders. As of November 30, 1998, on a pro forma basis, the Issuer's
Subsidiaries would have had no long-term Indebtedness outstanding other than
their guarantees of the Indebtedness of the Issuer under the Credit Facility
(which was not initially guaranteed by Centennial de Puerto Rico and its
subsidiaries) and the portion of the Indebtedness borrowed by Centennial de
Puerto Rico under the Credit Facility (which was guaranteed by Centennial
Cellular Operating and Centennial de Puerto Rico's subsidiaries), all of which
effectively would have ranked senior to the New Notes.
 
                                      122
<PAGE>
 
      Upon consummation of the Merger, Centennial Finance Corp., which was
initially an obligor on the Old Notes, merged with and into Centennial and
Centennial became a joint and several obligor on the Notes under the Indenture
pursuant to an Assumption Agreement and Supplemental Indenture to the
Indenture. The Indenture provides that the New Notes are senior subordinated
obligations of any co-obligor to the same extent as the obligations are senior
subordinated obligations of the Issuer. As of November 30, 1998, on a pro forma
basis, Centennial (without its subsidiaries) would have had $936.0 million in
aggregate principal amount of Senior Indebtedness outstanding (representing its
guarantee under the Credit Facility).
 
Optional Redemption by the Co-Obligors
 
      General. The New Notes will be subject to redemption at any time on or
after December 15, 2003, at the option of the Co-Obligors, in whole or in part,
on not less than 30 nor more than 60 days' prior notice in amounts of $1,000 or
an integral multiple thereof at the following redemption prices (expressed as
percentages of the principal amount), if redeemed during the 12-month period
beginning December 15 of the years indicated below:
 
<TABLE>

</TABLE>
 
      and thereafter at 100% of the principal amount, in each case, together
with accrued and unpaid interest, if any, to the redemption date (subject to
the rights of holders of record on relevant record dates to receive interest
due on an interest payment date).
 
      Upon Certain Equity Offerings. In addition, at any time after
consummation of the Merger and prior to December 15, 2001, the Co-Obligors, at
their option, may use the net cash proceeds of one or more Public Equity
Offerings or Strategic Equity Offerings in a single transaction or a series of
related transactions to redeem up to an aggregate of 35% of the aggregate
principal amount of Notes originally issued under the Indenture at a redemption
price equal to 110.750% of the aggregate principal amount thereof, plus accrued
and unpaid interest thereon, if any, to the redemption date (subject to the
rights of holders of record on relevant record dates to receive interest due on
an interest payment date); provided that at least 65% of the initial aggregate
principal amount of Notes remains outstanding immediately after the occurrence
of such redemption; provided, further, that any such redemption with respect to
a Strategic Equity Offering may not occur in connection with or after the
occurrence of a Change of Control; provided, further, that any such net
proceeds received by Centennial or any other direct or indirect parent of the
Issuer are first contributed to the Issuer as a capital contribution prior to
any such redemption. In order to effect the foregoing redemption, the Co-
Obligors must mail a notice of redemption no later than 30 days after the
closing of the related Public Equity Offering or Strategic Equity Offering and
must consummate such redemption within 60 days of the closing of the Public
Equity Offering or Strategic Equity Offering.
 
      Upon a Change of Control. In addition, the Notes may be redeemed upon a
Change of Control at any time prior to December 15, 2003, at the option of the
Co-Obligors, in whole and not in part, within 60 days of such Change of Control
at a redemption price equal to (i) 100% of the principal amount of the Notes,
plus (ii) accrued interest to the redemption date (subject to the rights of
holders of record on relevant record dates to receive interest due on an
interest payment date) plus (iii) the Applicable Premium, if any. In no event
will the redemption price of the Notes be less than 105.375% (the redemption
price for the Notes on December 15, 2003) of the principal amount of the Notes,
plus accrued interest to the applicable redemption date.
 
      Procedures. Subject to the following, notice of any redemption will be
sent, by first-class mail, at least 30 days and not more than 60 days prior to
the date fixed for redemption to the Holder of each Note to be
 
                                      123
<PAGE>
 
redeemed to such Holder's last address as then shown upon the books of the
Registrar. Any notice which relates to a Note to be redeemed in part only must
state the portion of the principal amount to be redeemed and must state that on
and after the date fixed for redemption, upon surrender of such Note, a new
Note or Notes in a principal amount equal to the unredeemed portion thereof
will be issued. On and after the date fixed for redemption, interest will cease
to accrue on the portions of the Notes called for redemption.
 
      In the case of a partial redemption, the Trustee shall select the Notes
or portions thereof for redemption in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed,
or if the Notes are not so listed, on a pro rata basis, by lot or by any other
manner as it deems appropriate and fair; provided, that any such redemption
pursuant to the provisions relating to a Public Equity Offering or a Strategic
Equity Offering shall be made on a pro rata basis or on as nearly a pro rata
basis as practicable (subject to the procedures of DTC or any other
depositary). The Notes may be redeemed in part in multiples of $1,000 only.
 
Sinking Fund
 
      The New Notes will not have the benefit of a sinking fund.
 
Security
 
      Pursuant to the Pledge and Escrow Agreement, upon the closing of the
Merger, the Trustee purchased and holds in pledge for the benefit of the
Holders of the Notes the Pledged Securities in such amount and with such
maturity as will be sufficient upon receipt of scheduled interest and principal
payments of such securities, based on the report of an internationally
recognized firm of independent public accountants or a nationally recognized
investment banking firm, in either case selected by the Co-Obligors, to provide
for payment in full of the first three scheduled interest payments (excluding
Additional Interest) due on the Notes (unless already paid). The Pledged
Securities will consist of three groups of Government Securities, one for each
of the first three scheduled interest payments. Each such group will consist of
Government Securities maturing on, or as nearly as possible prior to, the date
of the corresponding scheduled interest payment in an aggregate amount
sufficient upon receipt of scheduled interest and principal payments of such
securities (determined as described in the preceding sentence) to provide for
payment in full of such scheduled interest payment. The Co-Obligors used
approximately $60 million of the net proceeds of the Offering retained in the
Initial Escrow and Pledge Account to acquire the Pledged Securities at the time
of the closing of the Merger. The Pledged Securities were pledged by the Co-
Obligors to the Trustee for the benefit of the Holders of Notes pursuant to the
Pledge and Escrow Agreement and are held by the Trustee in the Subsequent
Collateral Investments Account (or other accounts). Pursuant to the Pledge and
Escrow Agreement, immediately prior to an Interest Payment Date on the Notes,
the Co-Obligors may either deposit with the Trustee, from funds otherwise
available to the Co-Obligors, cash sufficient to pay the interest scheduled to
be paid on such date, or the Co-Obligors may direct the Trustee to release from
the Subsequent Collateral Investments Account (or other accounts) proceeds
sufficient to pay interest then due. In the event that the Co-Obligors exercise
the former option, the Co-Obligors may thereafter direct the Trustee to release
to the Co-Obligors proceeds or Pledged Securities from the Subsequent
Collateral Investments Account (or other accounts) in like amount. A failure by
the Co-Obligors to pay interest on the Notes in a timely manner on or prior to
the first three scheduled interest payments will constitute an immediate Event
of Default under the Indenture, with no grace or cure period.
 
      Interest earned on the Pledged Securities will be held in a cash
collateral account by the Trustee. In the event that collectively the funds
held in the cash collateral account and the Pledged Securities held in the
Subsequent Collateral Investments Account exceed the amount sufficient, based
on the report of an internationally recognized firm of independent public
accountants or a nationally recognized investment banking firm, in either case
selected by the Co-Obligors, to provide for payment in full of the first three
scheduled interest payments (excluding Additional Interest unless then due and
payable) due on the Notes (or, in the event an interest payment or payments
have been made, an amount sufficient to provide for payment in
 
                                      124
<PAGE>
 
full or any interest payments remaining, up to and including the third
scheduled interest payment) the Trustee will be permitted to release to the Co-
Obligors at the Co-Obligors' request any such excess amount. The Notes will be
secured by a first priority security interest in the Pledged Securities in the
Subsequent Collateral Investments Account and the cash collateral account and,
accordingly, the Pledged Securities in the Subsequent Collateral Investments
Account and the cash collateral account will also secure repayment of the
principal amount of the Notes to the extent of such security. The Pledge and
Escrow Agreement allows the Co-Obligors to substitute Marketable U.S.
Securities for the Government Securities originally pledged as collateral;
provided, however, that the Marketable U.S. Securities so substituted must have
a value (measured at the date of substitution), in the opinion of a nationally
recognized firm of independent public accountants selected by the Co-Obligors,
at least equal to 125.0% of the amount of all of the first three scheduled
interest payments on the Notes that are unpaid (or the pro rata portion of such
interest payments equal to the percentage of such interest payments to be
secured by such Marketable U.S. Securities) as of the date such Marketable U.S.
Securities are proposed to be substituted as security for the Co-Obligors's
obligations under the Pledge and Escrow Agreement.
 
      Under the Pledge and Escrow Agreement, assuming that the Co-Obligors make
the first three scheduled interest payments on the Notes in a timely manner,
all of the Pledged Securities will have been released from the Subsequent
Collateral Investments Account and thereafter the Notes will be unsecured.
 
Certain Covenants
 
      Repurchase of Notes at the Option of the Holder Upon a Change of
Control. The Indenture provides that, in the event that a Change of Control has
occurred, each Holder will have the right, at such Holder's option, pursuant to
an irrevocable and unconditional offer by the Co-Obligors (the "Change of
Control Offer"), to require the Co-Obligors to repurchase all or any part
(equal to $1,000 principal amount or an integral multiple thereof) of such
Holder's Notes, on a date (the "Change of Control Purchase Date") that is no
later than 45 Business Days after the occurrence of such Change of Control at a
cash price (the "Change of Control Purchase Price") equal to 101% of the
aggregate principal amount thereof, together with any accrued and unpaid
interest to the Change of Control Purchase Date. The Change of Control Offer
shall be made within 30 Business Days following a Change of Control and shall
remain open for 20 Business Days following its commencement (the "Change of
Control Offer Period"). Upon expiration of the Change of Control Offer Period,
the Co-Obligors shall purchase all Notes properly tendered in response to the
Change of Control Offer.
 
      On or before the Change of Control Purchase Date, the Co-Obligors will
(i) accept for payment Notes or portions thereof properly tendered pursuant to
the Change of Control Offer, (ii) deposit with the Paying Agent cash sufficient
to pay the Change of Control Purchase Price (together with accrued and unpaid
interest) of all Notes so tendered and (iii) deliver to the Trustee Notes so
accepted together with an Officers' Certificate listing the Notes or portions
thereof being purchased by the Co-Obligors. The Paying Agent promptly will
deliver to the Holders of Notes so accepted payment in an amount equal to the
Change of Control Purchase Price (together with any accrued and unpaid
interest), and the Trustee will promptly authenticate and mail or deliver to
such Holders a new Note equal in principal amount to any unpurchased portion of
the Note surrendered. Any Notes not so accepted will be promptly mailed or
delivered by the Co-Obligors to the Holder thereof. The Co-Obligors will
announce publicly the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Purchase Date.
 
      The Change of Control purchase feature of the Notes may make more
difficult or discourage a takeover of the Co-Obligors, and, thus, the removal
of incumbent management. The Change of Control purchase feature resulted from
negotiations between the Co-Obligors and the Initial Purchasers and is not the
result of any intention on the part of the Co-Obligors or their management to
discourage the acquisition of the Co-Obligors.
 
 
                                      125
<PAGE>
 
      The Credit Facility provides that certain change of control events with
respect to the Co-Obligors would constitute a default thereunder. Any future
credit agreements or other agreements to which any of the Co-Obligors or any of
their Subsidiaries becomes a party may contain similar restrictions and
provisions. In the event a Change of Control were to occur at a time when the
Co-Obligors are prohibited from purchasing Notes, the Co-Obligors could seek
the consent of their lenders to such purchase of Notes, or any of such
companies could attempt to refinance the borrowings that contain such
prohibition. If the Co-Obligors did not obtain such consents or repay such
borrowings, the Co-Obligors would not be able to purchase the Notes under a
Change of Control Offer. In such case, the Co-Obligors' failure to purchase
tendered Notes would constitute an Event of Default under the Indenture.
 
      If a Change of Control Offer is made, there can be no assurance that the
Co-Obligors will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Notes that might be delivered by holders of the
Notes seeking to accept the Change of Control Offer. See "--Ranking."
Centennial is a holding company with no material assets other than the stock of
the Issuer. The failure of the Co-Obligors to make or consummate the Change of
Control Offer or pay the Change of Control Purchase Price when due will give
the Trustee and the holders of the Notes the rights described under "Events of
Default."
 
      The term "all or substantially all" as used in the definition of "Change
of Control" has not been interpreted under New York law (which is the governing
law of the Indenture) to represent a specific quantitative test. As a
consequence, in the event the holders of the Notes elected to exercise their
rights under the Indenture and the Co-Obligors elected to contest such
election, there could be no assurance as to how a court interpreting New York
law would interpret the phrase.
 
      The provisions of the Indenture do not afford holders of the Notes the
right to require the Co-Obligors to repurchase the Notes in the event of a
highly leveraged transaction or certain transactions with the Co-Obligors'
management or Affiliates, including a reorganization, restructuring, merger or
similar transaction (including, in certain circumstances, an acquisition of the
Co-Obligors by management or its affiliates) involving the Co-Obligors that may
adversely affect holders of the Notes, if such transaction is not a transaction
defined as a Change of Control. A transaction involving the Co-Obligors'
management or Affiliates, or a transaction involving a recapitalization of the
Co-Obligors, will result in a Change of Control if it is the type of
transaction specified by such definition.
 
      Any Change of Control Offer will be made in compliance with all
applicable laws, rules and regulations, including, if applicable, Regulation
14E under the Exchange Act and the rules thereunder and all other applicable
Federal and state securities laws and the Co-Obligors may modify a Change of
Control Offer to the extent necessary to effect such compliance.
 
      Limitation on Incurrence of Additional Indebtedness. The Issuer will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, issue, create, incur, assume, guarantee or otherwise directly or
indirectly become liable for, or otherwise become responsible for, contingently
or otherwise (individually or collectively, to "Incur" or, as appropriate, an
"Incurrence"), any Indebtedness (including any Acquired Indebtedness). Neither
the accrual of interest (including the issuance of "pay in kind" securities or
similar instruments in respect of such accrued interest) pursuant to the terms
of Indebtedness Incurred in compliance with this covenant, nor the accretion of
original issue discount, nor the mere extension of the maturity of any
Indebtedness shall be deemed to be an Incurrence of Indebtedness.
 
      Notwithstanding the foregoing, the Issuer and any Guarantor may Incur
Indebtedness (including Acquired Indebtedness) and any Restricted Subsidiary
may Incur Acquired Indebtedness if the Issuer's Annual Operating Cash Flow
Ratio, after giving effect to the Incurrence of such Indebtedness and the
application of the proceeds therefrom, would have been less than 8.25 to 1.0 at
any time prior to December 31, 2000 and 7.5 to 1.0 thereafter.
 
 
                                      126
<PAGE>
 
      In addition, the foregoing limitations will not apply to the Incurrence
of the following:
 
     (i) Indebtedness of the Issuer, any Guarantor or Centennial de Puerto
  Rico under the Credit Facility in an aggregate principal amount at any one
  time outstanding not to exceed $1.05 billion, reduced by permanent
  reductions in commitments in satisfaction of the Net Cash Proceeds
  application requirement set forth in "--Limitation on Asset Sales and Sales
  of Subsidiary Stock," provided, that the aggregate principal amount of
  Indebtedness of Centennial de Puerto Rico pursuant to this clause (i) shall
  not exceed 25% of the principal amount which may be borrowed pursuant to
  this clause (i);
 
     (ii) Indebtedness of the Issuer (a) pursuant to the Notes or (b)

is in compliance with the terms of the Indenture and such Restricted Subsidiary
is released from all guarantees, if any, by it of other Indebtedness of the
Issuer or any Restricted Subsidiaries or (ii) the release by the holders of the
Indebtedness of the Issuer described in clause (a) above or their guarantee by
such Restricted Subsidiary (including any deemed release upon payment in full
of all obligations under such Indebtedness), which resulted in the Notes being
guaranteed by such Restricted Subsidiary, at such time as (A) no other
Indebtedness of the Issuer has been guaranteed by such Restricted Subsidiary or
(B) the holders of all such other Indebtedness which is guaranteed by such
Restricted Subsidiary also release their guarantee by such Restricted

Indebtedness of the Issuer ranking on a parity with the Notes from time to time
outstanding with similar provisions requiring the Issuer to make an offer to
purchase or to redeem such Indebtedness with the proceeds from asset sales, pro

the case of Indebtedness issued with an original issue discount) of the Notes
and such other Indebtedness then outstanding or to the repurchase of the Notes
and such other Indebtedness pursuant to an irrevocable, unconditional offer
(the "Asset Sale Offer") to repurchase such Indebtedness at a purchase price
(the "Asset Sale Offer Price") of 100% of the principal amount thereof in the
case of the Notes or 100% of the principal amount (or accreted value in the
case of Indebtedness issued with an original issue discount) of such
Indebtedness, plus, in each case, accrued interest to the date of payment, made

the Asset Sale Offer Amount is (i) invested (or committed, pursuant to a
binding commitment subject only to reasonable, customary closing conditions, to
be invested, and in fact is so invested, within an additional 90 days) in
tangible assets and property (other than notes, obligations or securities),
which in the good faith reasonable judgment of the Issuer are of a type used in
a Related Business, or Capital Stock of a Person (which, if such Person becomes
a Subsidiary of the Issuer by virtue of such Asset Sale, shall initially be
designated a Restricted Subsidiary) all or substantially all of whose assets
and property (in the good faith reasonable judgment of the Issuer) are of a
type used in a Related Business (provided that, with respect to such Capital
Stock, all of the requirements of the last proviso of clause (v) of the
following paragraph shall have been satisfied) or (ii) used to permanently
retire Senior Indebtedness of the Issuer or any Guarantor or Indebtedness of
any Restricted Subsidiary (which is not a Guarantor), (2) with respect to any
transaction or related series of transactions of securities, property or assets
with an aggregate fair market value in excess of $2,500,000, at least 75% of
the value of consideration for the assets disposed of in such Asset Sale
(excluding (a) Senior Indebtedness under a bank credit facility (and any
Refinancing Indebtedness issued to refinance any such Indebtedness) or any
Indebtedness of a Restricted Subsidiary in each case that is assumed by a
transferee which assumption permanently reduces the amount of Indebtedness
outstanding on the Issue Date and permitted to have been Incurred pursuant to
the covenant "--Limitation on Incurrence of Additional Indebtedness" (including
that in the case of a revolver or similar arrangement that makes credit
available, such commitment is permanently reduced by such amount), (b) Purchase
Money Indebtedness secured exclusively by the assets subject to such Asset Sale
which is assumed by a transferee and (c) marketable securities that are

promptly converted into cash or Cash Equivalents) consists of cash or Cash
Equivalents, provided that any cash or Cash Equivalents received within 12
months following any such Asset Sale upon conversion of any property or assets
(other than in the form of cash or Cash Equivalents) received in consideration
of such Asset Sale shall be applied promptly in the manner required of Net
Cash Proceeds of any such Asset Sale as set forth above (provided further that
the Issuer and its Restricted Subsidiaries shall not be required to receive
any cash in connection with the transfer or contribution of assets to a joint
venture), and (3) the Board of Directors of the Issuer determines in good
faith that the Issuer or such Restricted Subsidiary, as applicable, would
receive fair market value in consideration of such Asset Sale. The Indenture
provides that an Asset Sale Offer may be deferred until the accumulated Net
Cash Proceeds from Asset Sales not applied to the uses set forth in (1)(b)
above exceeds $15,000,000 and that each Asset Sale Offer shall remain open for
20 Business Days following its commencement and no longer, except as otherwise
required by applicable law (the "Asset Sale Offer Period"). Upon expiration of
the Asset Sale Offer Period, the Issuer shall apply the Asset Sale Offer
Amount, plus an amount equal to accrued interest to the purchase of all
Indebtedness properly tendered (on a pro rata basis as described above if the
Asset Sale Offer Amount is insufficient to purchase all Indebtedness so
tendered) at the Asset Sale Offer Price (together with accrued interest).
 
      Notwithstanding the foregoing provisions of the prior paragraph:
 
    (i) the Issuer and its Restricted Subsidiaries may, in the ordinary
  course of business, convey, sell, lease, transfer, assign or otherwise
  dispose of assets acquired and held for resale in the ordinary course of
  business;
 
    (ii) the Issuer and its Restricted Subsidiaries may convey, sell, lease,
  transfer, assign or otherwise dispose of assets pursuant to and in
  accordance with the "--Limitation on Mergers, Sales or Consolidations"
  covenant;
 
    (iii) the Issuer and its Restricted Subsidiaries may sell or dispose of
  damaged, worn out or other obsolete property in the ordinary course of
  business so long as such property is no longer necessary for the proper
  conduct of the business of the Issuer or such Restricted Subsidiary, as
  applicable;
 
    (iv) the Issuer and its Restricted Subsidiaries may convey, sell, lease,
  transfer, assign or otherwise dispose of assets to the Issuer or any of its
  Restricted Subsidiaries in accordance with the terms of the Indenture; and
 
    (v) the Issuer and its Restricted Subsidiaries may, in the ordinary
  course of business (or, if otherwise than in the ordinary course of
  business, in the case of exchanges in excess of $15 million upon receipt of
  a favorable written opinion by an independent financial advisor of national
  reputation as to the fairness from a financial point of view to the Issuer
  or such Restricted Subsidiary of the proposed transaction), exchange all or
  a portion of its property, businesses or assets for property, businesses or
  assets which, or Capital Stock of a Person all or substantially all of
  whose assets, are of a type used in the business of the Issuer on the date
  of the Indenture or a Related Business (provided that such Person shall
  initially be designated a Restricted Subsidiary if such Person becomes a
  Subsidiary of the Issuer by virtue of such Asset Sale), or a combination of
  any such property, businesses or assets, or Capital Stock of such a Person
  and cash or Cash Equivalents; provided that (i) a majority of the
  Disinterested Directors of the Board of Directors of the Issuer shall have
  approved a resolution of the Board of Directors that such exchange is fair
  to the Issuer or such Restricted Subsidiary, as the case may be, and (ii)
  any cash or Cash Equivalents received pursuant to any such exchange shall
  be applied in the manner applicable to Net Cash Proceeds from an Asset Sale
  as set forth pursuant to the provisions of the immediately preceding
  paragraph of this covenant; and provided, further, that any Capital Stock
  of a Person received in an Asset Sale pursuant to this clause (v) shall be
  owned directly by the Issuer or a Restricted Subsidiary and, when combined
  with the Capital Stock of such Person already owned by the Issuer and its
  Restricted Subsidiaries, shall constitute a majority of the voting power
  and Capital Stock of such Person.

      Restricted Payments that are made in compliance with "--Limitation on
Restricted Payments" shall not be deemed to be Asset Sales.
 
      Any Asset Sale Offer shall be made in compliance with all applicable
laws, rules, and regulations, including, if applicable, Regulation 14E of the
Exchange Act and the rules and regulations thereunder and all other applicable
Federal and state securities laws.
 
      Limitation on Liens. The Issuer will not, and will not cause or permit
any Restricted Subsidiary to, directly or indirectly, create, incur or affirm
any Lien of any kind securing any Pari Passu Indebtedness or Subordinated
Indebtedness (including any assumption, guarantee or other liability with
respect thereto by any Restricted Subsidiary) upon any property or assets
(including any intercompany notes) of the Issuer or any Restricted Subsidiary
owned on the date of the Indenture or acquired after the date of the Indenture,
or any income or profits therefrom, unless the Notes are directly secured
equally and ratably with (or, in the case of Subordinated Indebtedness, prior
or senior thereto, with the same relative priority as the Notes shall have with
respect to such Subordinated Indebtedness) the obligation or liability secured
by such Lien except for Liens (A) securing any Indebtedness which became
Indebtedness pursuant to a transaction permitted under "--Limitation on Merger,
Sale or Consolidation" or securing Acquired Indebtedness which was created
prior to (and not created in connection with, or in contemplation of) the
incurrence of such Pari Passu Indebtedness or Subordinated Indebtedness
(including any assumption, guarantee or other liability with respect thereto by
any Restricted Subsidiary) and which Indebtedness is permitted under the
provisions of "--Limitation on Incurrence of Additional Indebtedness" or (B)
securing any Indebtedness incurred in connection with any refinancing, renewal,
substitutions or replacements of any such Indebtedness described in clause (A),
so long as the aggregate principal amount of Indebtedness represented thereby
(or if such Indebtedness provides for an amount less than the principal amount
thereof to be due and payable upon a declaration of acceleration of the
maturity thereof, the original issue price of such Indebtedness plus any
accreted value attributable thereto since the original issuance of such
Indebtedness) is not increased by such refinancing by an amount greater than
the lesser of (i) the stated amount of any premium or other payment required to
be paid in connection with such a refinancing pursuant to the terms of the
Indebtedness being refinanced or (ii) the amount of premium or other payment
actually paid at such time to refinance the Indebtedness, plus, in either case,
the amount of expenses of the Issuer incurred in connection with such
refinancing, provided, however, that in the case of clauses (A) and (B), any
such Lien only extends to the assets that were subject to such Lien securing
such Indebtedness prior to the related acquisition by the Issuer or its
Restricted Subsidiaries. Notwithstanding the foregoing, any Lien securing the
Notes granted pursuant to this covenant shall be automatically and
unconditionally released and discharged upon the release by the holders of the
Pari Passu Indebtedness or Subordinated Indebtedness described above of their
Lien on the property or assets of the Issuer or any Restricted Subsidiary
(including any deemed release upon payment in full of all obligations under
such Indebtedness), at such time as the holders of all such Pari Passu
Indebtedness or Subordinated Indebtedness also release their Lien on the
property or assets of the Issuer or such Restricted Subsidiary, or upon any
sale, exchange or transfer to any Person not an Affiliate of the Issuer of the
property or assets secured by such Lien, or of all of the Capital Stock held by
the Issuer or any Restricted Subsidiary in, or all or substantially all the
assets of, any Restricted Subsidiary creating such Lien.
 
      Limitation on Merger, Sale or Consolidation. The Issuer will not
consolidate with or merge with or into another Person, or sell, lease, convey,
transfer or otherwise dispose of all or substantially all of its properties and
assets (computed on a consolidated basis), whether in a single transaction or a
series of related transactions, to another Person or group of affiliated
Persons, and the Issuer will not permit any Restricted Subsidiary to enter into
any such transaction or series of transactions which would result in a sale,
lease, conveyance, transfer or other disposition of all or substantially all of
the properties and assets of the Issuer on a consolidated basis, unless (i)
either (a) the Issuer is the continuing entity or (b) the resulting, surviving
or transferee entity is an entity organized under the laws of the United
States, any state thereof or the District of Columbia and expressly assumes by
supplemental indenture all of the obligations of the Issuer in connection with
the Notes, the Indenture and the Registration Rights Agreement, as the case may
be, and the Notes, the Indenture and the Registration Rights Agreement will
remain in full force and effect as so supplemented (and
 
                                      135
<PAGE>
 
any Guarantee shall be confirmed as applied to the surviving entity's
obligations); (ii) no Default or Event of Default shall exist or shall occur
immediately after giving effect on a pro forma basis (and treating any
Indebtedness not previously an obligation of the Issuer or any of its
Restricted Subsidiaries which becomes the obligation of the Issuer or any of
its Restricted Subsidiaries as a result of such transaction as having been
incurred at the time of such transaction) to such transaction; (iii)
immediately before and immediately after giving effect to such transaction on a
pro forma basis (on the assumption that the transaction occurred on the first
day of the four-quarter period for which financial statements are available
ending immediately prior to the consummation of such transaction with the
appropriate adjustments with respect to the transaction being included in such
pro forma calculation), either the Issuer or resulting surviving or transferee
entity would immediately thereafter be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Annual Operating Cash Flow Ratio
provision set forth in the second paragraph of the "--Limitation on Incurrence
of Additional Indebtedness" covenant or such Annual Operating Cash Flow Ratio
would be lower than such ratio immediately prior to such transaction; (iv) at
the time of the transaction any co-obligor, unless it is the other party to the
transaction described above, will have by supplemental indenture confirmed that
it remains a co-obligor under the Indenture and the Notes; (v) at the time of
the transaction each Guarantor, if any, unless it is the other party to the
transaction described above, will have by supplemental indenture confirmed that
its Guarantee shall apply to such Person's obligations under the Indenture and
the Notes; and (vi) at the time of the transaction the Issuer or the resulting
surviving or transferee entity will have delivered, or caused to be delivered,
to the Trustee, in form and substance reasonably satisfactory to the Trustee,
an officers' certificate and an opinion of counsel, each to the effect that
such consolidation, merger, transfer, sale, assignment, conveyance, transfer,
lease or other transaction and the supplemental indenture in respect thereof
comply with the Indenture and that all conditions precedent therein provided
for relating to such transaction have been complied with.
 
      Notwithstanding the foregoing, any Restricted Subsidiary may merge with
and into any other Restricted Subsidiary or the Issuer.
 
      Immediately upon consummation of the Merger, Finance Corp. shall merge
with and into Centennial and Centennial shall assume all of Finance Corp.'s
obligations under the Indenture and the Notes pursuant to an assumption
agreement in the form attached to the Indenture.
 
      Centennial will not, in a single transaction or through a series of
related transactions, consolidate with or merge with or into any other Person
(other than (i) the Issuer or any Guarantor, (ii) CCW Acquisition Corp. in
connection with the Merger or (iii) Finance Corp. upon consummation of the
Merger) or sell, assign, convey, transfer, lease or otherwise dispose of all or
substantially all of its properties and assets to any Person or group of
Persons (other than the Issuer or any Guarantor) unless at the time and after
giving effect thereto (i) either (a) Centennial will be the continuing
corporation or (b) the Person (if other than Centennial) formed by such
consolidation or into which Centennial is merged or the Person which acquires
by sale, assignment, conveyance, transfer, lease or disposition all or
substantially all of the properties and assets of Centennial on a Consolidated
basis will be a corporation duly organized and validly existing under the laws
of the United States of America, any state thereof or the District of Columbia
and such Person expressly assumes, by a supplemental indenture, in a form
reasonably satisfactory to the Trustee, all the obligations of Centennial under
the Notes and the Indenture and the Registration Rights Agreement and such
Note, Indenture and Registration Rights Agreement will remain in full force and
effect; (ii) immediately before and immediately after giving effect to such
transaction on a pro forma basis, no Default or Event of Default will have
occurred and be continuing; and (iii) at the time of the transaction Centennial
or the surviving entity will have delivered, or caused to be delivered, to the
Trustee, in form and substance reasonably satisfactory to the Trustee, an
officers' certificate and an opinion of counsel, each to the effect that such
consolidation, merger, transfer, sale, assignment, conveyance, lease or other
transaction and the supplemental indenture in respect thereof comply with the
Indenture and that all conditions precedent therein provided for relating to
such transaction have been complied with. In the event that Centennial shall
merge or consolidate with or into the Issuer, the provisions of the first
paragraph of this Section are also required to be satisfied.
 
                                      136
<PAGE>
 
      Upon any consolidation or merger or any transfer (other than a lease) of
all or substantially all of the assets of the Issuer or Centennial, as the case
may be in accordance with the foregoing, the successor corporation formed by
such consolidation or into which the Issuer or Centennial, as the case may be,
is merged or to which such transfer is made, shall succeed to, and be
substituted for, and may exercise every right and power of, the Issuer or
Centennial, as the case may be, under the Indenture with the same effect as if
such successor entity had been named therein as the Issuer or Centennial, as
the case may be, and the Issuer or Centennial, as the case may be (except in
connection with a transfer that results in the transfer of assets constituting
or accounting for less than 95% of the consolidated assets (as of the last
balance sheet available), revenues, or Annual Operating Cash Flow of the Issuer
or Centennial, as the case may be (as of the last twelve month period for which
financial statements are available), shall be released from the obligations
under the Notes and the Indenture.
 
      Limitation on Lines of Business. Neither the Issuer nor any of its
Restricted Subsidiaries shall directly or indirectly engage in any line or
lines of business activity other than that which, in the reasonable, good faith
judgment of the Board of Directors of the Issuer, is a Related Business.
 
      Limitation on Activities Prior to the Merger. Prior to consummation of
the Merger, the Co-Obligors may not, and must cause their Subsidiaries not to,
incur any Indebtedness or engage in any activities other than in connection
with the Merger and the Credit Facility.
 
      Transfer of Stock to the Issuer. Immediately following consummation of
the Merger, Centennial shall cause the Capital Stock of all of its existing
Subsidiaries and Minority Cellular Investment Interests to be contributed to
the Issuer and Centennial shall immediately thereafter have no material assets
other than its Investment in the Capital Stock of the Issuer.
 
      Limitation on Senior Subordinated Indebtedness. Each Issuer will not, and
will not permit or cause any Guarantor to, directly or indirectly, create,
incur, issue, assume, guarantee or otherwise in any manner become directly or
indirectly liable for or with respect to or otherwise permit to exist any
Indebtedness that is subordinate in right of payment to any Indebtedness of
such Co-Obligors or such Guarantor, as the case may be, unless such
Indebtedness is also pari passu with the Notes or the Guarantee of such
Guarantor or subordinated in right of payment to the Notes or such Guarantee at
least to the same extent as the Notes or such Guarantee are subordinated in
right of payment to Senior Indebtedness or Senior Indebtedness of such
Guarantor, as the case may be, as set forth in the Indenture.
 
      Limitation on Unrestricted Subsidiaries. The Indenture provides that the
Issuer may designate any Subsidiary (other than a Guarantor) as an
"Unrestricted Subsidiary" under the Indenture (a "Designation") only if:
 
    (a) no Default shall have occurred and be continuing at the time of or
  after giving effect to such Designation;
 
    (b) the Issuer would be permitted to make an Investment at the time of
  Designation (assuming the effectiveness of such Designation) pursuant to
  "--Limitation on Restricted Payments" above in an amount (the "Designation
  Amount") equal to the greater of (1) the net book value of the Issuer's
  interest in such Subsidiary calculated in accordance with GAAP or (2) the
  fair market value of the Issuer's interest in such Subsidiary as determined
  in good faith by the Issuer's board of directors;
 
    (c) such Unrestricted Subsidiary does not own any Capital Stock in any
  Restricted Subsidiary of the Issuer which is not simultaneously being
  designated an Unrestricted Subsidiary;
 
 
                                      137
<PAGE>
 
    (d) such Unrestricted Subsidiary is not liable, directly or indirectly,
  with respect to any Indebtedness other than Unrestricted Subsidiary
  Indebtedness, provided that an Unrestricted Subsidiary may provide a
  Guarantee for the Notes; and
 
    (e) such Unrestricted Subsidiary is not a party to any agreement,
  contract, arrangement or understanding at such time with the Issuer or any
  Restricted Subsidiary unless the terms of any such agreement, contract,
  arrangement or understanding are no less favorable to the Issuer or such
  Restricted Subsidiary than those that might be obtained at the time from
  Persons who are not Affiliates of the Issuer or, in the event such
  condition is not satisfied, the value of such agreement, contract,
  arrangement or understanding to such Unrestricted Subsidiary shall be
  deemed a Restricted Payment.
 
      In the event of any such Designation, the Issuer shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant
"--Limitation on Restricted Payments" for all purposes of the Indenture in the
Designation Amount.
 
      The Indenture will also provide that the Issuer shall not and shall not
cause or permit any Restricted Subsidiary to at any time (x) provide credit
support for (provided that operational contracts in the ordinary course of
business shall not be deemed credit support), or subject any of its property
or assets (other than the Capital Stock of any Unrestricted Subsidiary) to the
satisfaction of, any Indebtedness of any Unrestricted Subsidiary (including
any undertaking, agreement or instrument constituting such Indebtedness)
(other than Permitted Investments in Unrestricted Subsidiaries) or (y) be
directly or indirectly liable for any Indebtedness of any Unrestricted
Subsidiary. For purposes of the foregoing, the Designation of a Subsidiary of
the Issuer as an Unrestricted Subsidiary shall be deemed to be the Designation
of all of the Subsidiaries of such Subsidiary as Unrestricted Subsidiaries.
 
      The Issuer may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary (a "Revocation") if:
 
    (a) no Default shall have occurred and be continuing at the time of and
  after giving effect to such Revocation;
 
    (b) all Liens and Indebtedness of such Unrestricted Subsidiary
  outstanding immediately following such Revocation would, if incurred at
  such time, have been permitted to be incurred for all purposes of the
  Indenture; and
 
    (c) unless such redesignated Subsidiary shall not have any Indebtedness
  outstanding (other than Indebtedness that would be Permitted Indebtedness),
  immediately after giving effect to such proposed Revocation, and after
  giving pro forma effect to the incurrence of any such Indebtedness of such
  redesignated Subsidiary as if such Indebtedness was incurred on the date of
  the Revocation, the Issuer could incur $1.00 of additional Indebtedness
  (other than Permitted Indebtedness) pursuant to the covenant described
  under "--Limitation on Incurrence of Additional Indebtedness."
 
      All Designations and Revocations must be evidenced by a resolution of
the board of directors of the Issuer delivered to the Trustee certifying
compliance with the foregoing provisions.
 
      Provision of Financial Statements. Whether or not the Issuer is subject
to Section 13(a) or 15(d) of the Exchange Act, so long as any Notes are
outstanding, the Issuer will, to the extent permitted under the Exchange Act,
file with the Commission the annual reports, quarterly reports and other
documents which the Issuer would have been required to file with the
Commission pursuant to Section 13(a) or 15(d) if it were so subject, such
documents to be filed with the Commission on or prior to the date (the
"Required Filing Date") by which the Issuer would have been required so to
file such documents if it were so subject. The Issuer will also in any event
(x) within 15 days of each Required Filing Date (whether or not prior to the
120th calendar
 
                                      138

names and addresses appear in the security register, without cost to such
holders and (ii) file with the Trustee copies of the annual reports, quarterly
reports and other documents which the Issuer would have been required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act if
the Issuer were subject to either of such Sections and (y) if filing such
documents by the Issuer with the Commission is not permitted under the Exchange
Act, promptly upon written request and payment of the reasonable cost of
duplication and delivery, supply copies of such documents to any prospective
purchaser of Notes at the Issuer's cost. The Indenture also provides that, so
long as any of the Notes remain outstanding, the Issuer will make available to
any prospective purchaser of Notes or beneficial owner of Notes in connection
with any sale thereof the information required by Rule 144A(d)(4) under the
Securities Act, until such time as the Issuer has either exchanged the Notes
for securities identical in all material respects which have been registered
under the Securities Act or until such time as the holders thereof have
disposed of such Notes pursuant to an effective registration statement under
the Securities Act. The Issuer will be deemed to have satisfied the
requirements set forth above if (a) Centennial prepares, files, mails and
supplies reports and other documents prepared on a consolidated basis of the
types required above, in each case within the applicable time periods, (b) the
Issuer is not required to file such reports and other documents separately
under the applicable rules and regulations of the Commission (after giving
effect to any exemptive relief) because of the filings made by Centennial, (c)
Centennial does not own assets in excess of $10 million other than the Capital
Stock of the Issuer, and (d) Centennial does not have outstanding Indebtedness
in excess of $10 million (other than indebtedness under the Mezzanine Financing

      Amendments to Mezzanine Financing. The Indenture provides that the
Mezzanine Financing shall be in substantially the form attached to the
Indenture and Centennial shall not amend the terms of the Mezzanine Financing
in a manner adverse to the Holders.
 
      Additional Covenants. The Indenture also contains covenants with respect
to the following matters: (i) payment of principal, premium and interest; (ii)
maintenance of an office or agency in The City of New York; (iii) arrangements
regarding the handling of money held in trust; (iv) maintenance of corporate
existence; (v) payment of taxes and other claims; (vi) maintenance of

Corp. or the Issuer to pay any installment of interest on the Notes as and when

$20,000,000 (exclusive of any portion of any such payment covered by insurance,
if and to the extent the insurer has acknowledged in writing its liability
therefor), at any one time rendered against Finance Corp., the Issuer or any of
its Restricted Subsidiaries and not stayed, bonded or discharged within 60
days. The Indenture provides that, if a Default occurs and is continuing, the
Trustee must, within 90 days after the occurrence of such Default, give to the
Holders notice of such Default.
 
      If an Event of Default occurs and is continuing (other than an Event of
Default specified in clauses (iv) and (v) above relating to Centennial, the
Issuer or any Significant Restricted Subsidiary), then in every such case,
unless the principal of all of the Notes shall have already become due and
payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, by notice in writing to the
Issuer (and to the Trustee if given by Holders) (an "Acceleration Notice"), may
declare all principal of the Notes (or the Change in Control Purchase Price if
the Event of Default includes failure to pay the Change in Control Purchase
Price) (or the Special Redemption Price in connection with any Special
Mandatory Redemption if the Event of Default relates to failure to make payment
in connection with the Special Mandatory Redemption), determined as set forth
below, including in each case accrued interest thereon to be due and payable
immediately; provided that so long as the Credit Facility shall be in full
force and effect, if an Event of Default shall have occurred and be continuing
(other than as specified in clauses (iv) or (v) with respect to Centennial, the
Issuer or any Significant Restricted Subsidiary), any such acceleration shall
not be effective until the earlier to occur of (x) five business days following
delivery of a written notice of such acceleration of the Notes to the agent
under the Credit Facility and (y) the acceleration of any Indebtedness under
the Credit Facility. If an Event of Default specified in clauses (iv) and (v)
above relating to Centennial, the Issuer or any Restricted Subsidiary occurs,
all principal and accrued interest thereon will be immediately due and payable
on all outstanding Notes without any declaration or other act on the part of
Trustee or the Holders. The Holders of a majority in aggregate principal amount
of Notes generally are authorized to rescind such acceleration if all existing
Events of Default, other than the non-payment of the principal of, premium, if
any, and interest on the Notes which have become due solely by such
acceleration, have been cured or waived.
 
                                      140
<PAGE>
 
      The Holders of a majority in aggregate principal amount of the Notes at
the time outstanding may waive on behalf of all the Holders any Default, except
a Default in the payment of principal of or interest on any Note not yet cured,
or a Default with respect to any covenant or provision which cannot be modified
or amended without the consent of the Holder of each outstanding Note affected.
Subject to the provisions of the Indenture relating to the duties of the
Trustee, the Trustee will be under no obligation to exercise any of its rights
or powers under the Indenture at the request, order or direction of any of the
Holders, unless such Holders have offered to the Trustee reasonable security or
indemnity. Subject to all provisions of the Indenture and applicable law, the
Holders of a majority in aggregate principal amount of the Notes at the time
outstanding will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee.
 
      No holder of any of the Notes has any right to institute any proceedings
with respect to the Indenture or any remedy thereunder, unless the holders of
at least 25% in aggregate principal amount of the outstanding Notes have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as Trustee under the Notes and the Indenture, the Trustee has
failed to institute such proceeding within 15 days after receipt of such notice
and the Trustee, within such 15-day period, has not received directions
inconsistent with such written request by holders of a majority in aggregate
principal amount of the outstanding Notes. Such limitations do not, however,
apply to a suit instituted by a holder of a Note for the enforcement of the
payment of the principal of, premium, if any, or interest on such Note on or
after the respective due dates expressed in such Note.
 
      The Co-Obligors are required to notify the Trustee within five business
days of the occurrence of any Default. The Co-Obligors are required to deliver
to the Trustee, not more than 120 days after the end of each fiscal year, a
written statement as to compliance with the Indenture, including whether or not
any Default has occurred.
 
      The Trust Indenture Act contains limitations on the rights of the
Trustee, should it become a creditor of Centennial, the Issuer or any
Guarantor, if any, to obtain payment of claims in certain cases or to realize
on certain property received by it in respect of any such claims, as security
or otherwise. The Trustee is permitted to engage in other transactions,
provided that if it acquires any conflicting interest it must eliminate such
conflict upon the occurrence of an Event of Default or else resign.
 
Legal Defeasance and Covenant Defeasance
 
      The Indenture provides that the Issuer may, at its option and at any
time, elect to have the obligations of Centennial, the Issuer, any Guarantor
and any other obligor upon the Notes discharged with respect to the outstanding
Notes ("Legal Defeasance"). Such Legal Defeasance means that Centennial, the
Issuer, any such Guarantor and any other obligor under the Indenture shall be
deemed to have paid and discharged the entire indebtedness represented, and the
Indenture shall cease to be of further effect as to all outstanding Notes,
except as to (i) rights of Holders to receive payments in respect of the
principal of, premium, if any, and interest on such Notes when such payments
are due from the trust funds; (ii) the Co-Obligors' obligations with respect to
such Notes concerning issuing temporary Notes, registration of Notes,
mutilated, destroyed, lost or stolen Notes, and the maintenance of an office or
agency for payment and money for security payments held in trust; (iii) the
rights, powers, trust, duties, and immunities of the Trustee, and the Issuer's
obligations in connection therewith; and (iv) the Legal Defeasance provisions
of the Indenture. In addition, the Issuer may, at its option and at any time,
elect to have the obligations of Centennial, the Issuer and any Guarantor
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Notes. In the event Covenant Defeasance occurs, certain events (not
including events described in clauses (i), (ii), (iv) (with respect to the Co-
Obligors) and (v) (with respect to the Co-Obligors) described under "--Events
of Default") will no longer constitute an Event of Default with respect to the
Notes.

<PAGE>
 
      In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders, U.S. Legal Tender, non-callable government securities or a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay the
principal of, premium, if any, and interest on such Notes on the stated date
for payment thereof or on any redemption date of such principal or installment
of principal of, premium, if any, or interest on such Notes, and the holders of
Notes must have a valid, perfected, exclusive security interest in such trust;
(ii) in the case of Legal Defeasance, the Issuer shall have delivered to the
Trustee an opinion of counsel in the United States reasonably acceptable to the
Trustee confirming that (A) the Issuer has received from, or there has been
published by the Internal Revenue Service, a ruling or (B) since the date of
the Indenture, there has been a change in the applicable Federal income tax
law, in each case to the effect that, and based thereon such opinion of counsel
shall confirm that, the holders of such Notes will not recognize income, gain
or loss for Federal income tax purposes as a result of such Legal Defeasance,
and will be subject to Federal income tax in the same amount, in the same
manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; (iii) in the case of Covenant Defeasance, the
Issuer shall have delivered to the Trustee an opinion of counsel in the United
States reasonably acceptable to such Trustee confirming that the holders of
such Notes will not recognize income, gain or loss for Federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred; (iv) no
Default or Event of Default shall have occurred and be continuing on the date
of such deposit or insofar as Events of Default from bankruptcy or insolvency
events are concerned, at any time in the period ending on the 91state of
deposit (other than a Default which results from the borrowing of amounts to
finance the defeasance and which borrowing does not result in a breach or
violation of, or constitute a default under, any other material agreement or
instrument to which Centennial, the Issuer or any Restricted Subsidiary is a
party or to which it is bound) (it being understood that such condition will
not be satisfied until the expiration of such 91-day period); (v) the Issuer
shall have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee to the effect that (assuming that no
holder of any Notes would be considered an insider of the Issuer under any
applicable bankruptcy or insolvency law) after the 91st day following the
deposit, the trust funds will not be subject to the effect of any applicable
bankruptcy, insolvency, reorganization or similar laws affecting creditors
rights generally; (vi) such defeasance or covenant defeasance shall not cause
the Trustee for the Notes to have a conflicting interest for purposes of the
Trust Indenture Act with respect to any securities of the Issuer or any
Guarantor; (vii) such Legal Defeasance or Covenant Defeasance shall not result
in a breach or violation of, or constitute a default under the Indenture or any
other material agreement or instrument to which Centennial, the Issuer or any
of their Subsidiaries is a party or by which Centennial, the Issuer or any of
their Subsidiaries is bound; (viii) the Issuer shall have delivered to the
Trustee an officers' certificate stating that the deposit was not made by the
Issuer with the intent of preferring the Holders of such Notes over any other
creditors of the Issuer or with the intent of defeating, hindering, delaying or
defrauding any other creditors of the Issuer or others; and (ix) the Issuer
shall have delivered to the Trustee an officers' certificate and opinion of
counsel each stating that all conditions precedent provided for or relating to
the Legal Defeasance or the Covenant Defeasance have been complied with.

Merger and to Centennial Cellular Corp. after the Merger.
 
Satisfaction and Discharge
 
      The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights of registration of transfer or exchange of the
Notes as expressly provided for in the Indenture) as to all outstanding Notes
under the Indenture when (a) either (i) all such Notes theretofore
authenticated and delivered (except lost, stolen or destroyed Notes which have
been replaced or paid or Notes whose payment has been deposited in trust or
segregated and held in trust by the Issuer and thereafter repaid to the Issuer
or discharged from such trust as provided for in the Indenture) have been
delivered to the Trustee for cancellation or (ii) all Notes not theretofore
delivered to the Trustee for cancellation (x) have become due and payable, (y)
will become due and payable at their Stated Maturity within one year, or (z)
are to be called for redemption within
 
                                      142
<PAGE>
 
one year under arrangements satisfactory to the Trustee for the giving of
notice of redemption by the Trustee in the name, and at the expense, of the
Issuer; and Centennial, the Issuer or any Guarantor has irrevocably deposited
or caused to be deposited with the Trustee as trust funds in trust an amount in
United States dollars sufficient to pay and discharge the entire indebtedness
on the Notes not theretofore delivered to the Trustee for cancellation,
including principal of, premium, if any, and accrued interest at Maturity,
Stated Maturity or redemption date; (b) Centennial, the Issuer or any Guarantor
has paid or caused to be paid all other sums payable under the Indenture by
Centennial, the Issuer and any Guarantor; and (c) the Issuer and Centennial
have delivered to the Trustee an officers' certificate and an opinion of
independent counsel each stating that (i) all conditions precedent under the
Indenture relating to the satisfaction and discharge of such Indenture have
been complied with and (ii) such satisfaction and discharge will not result in
a breach or violation of, or constitute a default under, the Indenture or any
other material agreement or instrument to which Centennial, the Issuer, any
Guarantor or any Subsidiary is a party or by which Centennial, the Issuer, any
Guarantor or any Subsidiary is bound. References in this section to
"Centennial" refer to Finance Corp. before the Merger and to Centennial
Cellular Corp. after the Merger.
 
Amendments and Supplements
 
      The Indenture contains provisions permitting the Issuer, Centennial and
the Trustee to enter into a supplemental indenture for certain limited purposes
without the consent of the Holders. With the consent of the Holders of not less
than a majority in aggregate principal amount of the Notes at the time
outstanding, Centennial, the Issuer, each Guarantor, if any, and the Trustee
are permitted to amend or supplement the Indenture or any supplemental
indenture or modify the rights of the Holders; provided that no such
modification may, without the consent of each Holder affected thereby: (i)

time for payment) of interest thereon or any premium payable upon the
redemption thereof, or change the place of payment where, or the coin or
currency in which, any Note or any premium or the interest thereon is payable,
or impair the right to institute suit for the enforcement of any such payment
on or after the Stated Maturity thereof (or, in the case of redemption, on or
after the redemption date), or reduce the Change of Control Purchase Price or
the Asset Sale Offer Price or alter the redemption provisions or the provisions
of the "--Repurchase of Notes at the Option of the Holder Upon a Change of
Control" covenant, including, in each case, amending, changing or modifying any
definitions related thereto, but only to the extent such definitions relate
thereto, in a manner adverse to the Holders, (ii) reduce the percentage in
principal amount of the outstanding Notes, the consent of whose Holders is
required for any such amendment, supplemental indenture or waiver provided for

Notes, Centennial, the Issuer, any Guarantor, any other obligor under the Notes
and the Trustee may modify or amend the Indenture: (a) to evidence the

assumption by any such successor of the covenants of Centennial, the Issuer or
such Guarantor in the Indenture and in the Notes and in any Guarantee in
accordance with "--Certain Covenants--Limitation on Merger, Sale or
Consolidation" (including to execute a supplemental indenture upon consummation
of the Merger in which Centennial Cellular Corp. assumes the obligations under
the Indenture of Finance Corp.); (b) to add to the covenants of Centennial, the
Issuer, any Guarantor or any other obligor upon the Notes for the benefit of
the holders of the Notes or to surrender any right or power conferred upon
Centennial, the Issuer or any Guarantor or any other obligor upon the Notes, as
applicable, in the Indenture, in the Notes or in any Guarantee; (c) to
 
                                      143

cure any ambiguity, or to correct or supplement any provision in the Indenture,
the Notes or any Guarantee which may be defective or inconsistent with any
other provision in the Indenture, the Notes or any Guarantee or make any other
provisions with respect to matters or questions arising under the Indenture,
the Notes or any Guarantee; provided that, in each case, such provisions shall
not adversely affect the interest of the holders of the Notes; (d) to comply
with the requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act; (e) to add a
Guarantor under the Indenture; (f) to evidence and provide the acceptance of
the appointment of a successor Trustee under the Indenture; or (g) to mortgage,
pledge, hypothecate or grant a security interest in favor of the Trustee for
the benefit of the holders of the Notes as additional security for the payment
and performance of Centennial's, the Issuer's and any Guarantor's obligations
under the Indenture, in any property, or assets, including any of which are
required to be mortgaged, pledged or hypothecated, or in which a security
interest is required to be granted to the Trustee pursuant to the Indenture or
otherwise.
 
      The holders of a majority in aggregate principal amount of the Notes
outstanding may waive compliance with certain restrictive covenants and
provisions of the Indenture. References in this section to "Centennial" refer
to Finance Corp. before the Merger and to Centennial Cellular Corp. after the
Merger, unless otherwise indicated.
 
No Personal Liability of Partners, Stockholders, Officers, Directors
 
      The Indenture provides that no direct or indirect stockholder (or
partner, limited liability company member or employee of a stockholder),
employee, officer or director, as such, past, present or future of the Co-
Obligors or any successor entity or any Affiliate thereof shall have any
personal liability in respect of the obligations of the Co-Obligors under the
Indenture or the Notes by reason of his or its status as such stockholder,
employee, officer or director.
 
Governing Law
 
      The Indenture, the Notes and any Guarantee will be governed by, and
construed in accordance with, the laws of the State of New York, without giving
effect to the conflicts of law principles thereof.
 
Concerning the Trustee
 
      The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of Centennial or the Issuer, to obtain payment of
claims in certain cases, or to realize on certain property received in respect
of any such claim as security or otherwise. The Trustee will be permitted to
engage in other transactions; however, if it acquires any conflicting interest
it must eliminate such conflict within 90 days, apply to the Commission for
permission to continue as Trustee with such conflict or resign as Trustee.
 
      The holders of a majority in principal amount of the then outstanding
Notes will have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
occurs (which has not been cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any holder of Notes unless such holder shall have offered to
the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

the time such Person becomes a Restricted Subsidiary or (ii) assumed in
connection with the acquisition of assets from such Person, in each case, other

Person becoming a Restricted Subsidiary or such acquisition, as the case may
be. Acquired Indebtedness shall be deemed to be Incurred on the date of the
related acquisition of assets from any Person or the date the acquired Person
becomes a Restricted Subsidiary, as the case may be.
 
      "Affiliate" means, with respect to any specified Person, (i) any other

policies of a Person, directly or through one or more intermediaries, whether
through the ownership of voting securities, by contract, or otherwise, or (b)

the Transaction Date (after giving pro forma effect to the Incurrence of such
Indebtedness) (and without duplication of any Indebtedness that may be the
obligation of such Person and/or one or more of its Subsidiaries) divided by
(ii) the aggregate amount of Annual Operating Cash Flow of such Person
(determined on a pro forma basis after giving effect to all Investments in and
acquisitions or dispositions of any company or any business or any assets out
of the ordinary course of business, whether by merger, stock purchase or sale
or asset purchase or sale, made by such Person and its Subsidiaries from the
beginning of the Reference Period through the Transaction Date as if such
Investment, acquisition or disposition had occurred at the beginning of such
Reference Period); provided that, for purposes of such computation, in

definition shall be deemed to refer to the Issuer and its Restricted
Subsidiaries. Any such pro forma calculation may include adjustments for the

as a result of an acquisition by the Issuer or a Restricted Subsidiary which,
in the good faith judgment of the Issuer (as determined by a resolution of the
board of directors of the Issuer), will be eliminated or realized within one
year after the date of such transaction (provided that any such cost savings
are calculated in accordance with Regulation S-X under the Securities Act (or
any successor regulation)) or (b) any direct quantifiable savings from the
conversion of roaming expense which the Issuer will obtain within one year of
the transaction in the good faith judgment of the Board of Directors of the

services.

Book-Entry Delivery And Form
 
      The Global Note. The certificates representing the Old Notes were issued,
and the certificates representing the New Notes will be issued, in fully
registered form, without coupons. The Old Notes are represented by one or more
permanent global certificates in definitive, fully registered form without
interest coupons in an aggregate amount of $370 million (the "Initial Global
Note"). Except as described in the next paragraph, the New Notes initially will
be represented by one or more permanent global certificates in definitive,
fully registered form (the "Global Notes") and will be deposited with, or on
behalf of, the DTC (the "Depositary"), and registered in the name of Cede &
Co., as the DTC's nominee or will remain in the custody of the Trustee pursuant
to a FAST Balance Certificate Agreement between the DTC and the Trustee. If any
holder of Old Notes whose interest in such Old Notes is represented by the
Initial Global Note fails to tender in the Exchange Offer, the Company may
issue and deliver to such holder a separate certificate representing such
holder's Old Notes in registered form without interest coupons.
 
      Certain Book-Entry Procedures for Global Notes. The descriptions of the
operations and procedures of DTC that follow are provided solely as a matter of
convenience. These operations and procedures are solely within the control of
the respective settlement systems and are subject to change by them from time
to time. The Issuer takes no responsibility for these operations and procedures
and urges investors to contact DTC or its participants directly to discuss
these matters.
 
      DTC has advised the Issuer as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its participants ("participants") and facilitate the clearance
and settlement of securities transactions between participants through
electronic book-entry changes in accounts of its participants, thereby
eliminating the need for physical transfer and delivery of certificates.
Participants include securities brokers and dealers, banks, trust companies and
clearing corporations and may include certain other organizations. Indirect
access to the DTC system is available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly ("indirect
participants").
 
      Pursuant to procedures established by DTC, (i) upon the issuance of the
Initial Global Certificate, DTC credited, on its internal system, the
respective principal amount of the individual beneficial interests represented
by such Global Notes to the accounts with DTC of the participants through which
such interests are held and (ii) ownership of beneficial interest in the Global
Notes are shown on, and the transfer of that ownership is effected only
through, records maintained by DTC or its nominees (with respect to interest of
participants) and the records of participants and indirect participants (with
respect to interests of persons other than participants).
 
      As long as DTC, or its nominee, is the registered Holder of a Global
Note, DTC or such nominee, as the case may be, will be considered the sole
owner and Holder of the Notes represented by such Global Note for all purposes
under the Indenture and the Notes. Except in the limited circumstances
described below, owners of beneficial interests in a Global Note will not be
entitled to have any portions of such Global Note registered in their names,
and will not receive or be entitled to receive physical delivery of Notes in
definitive
 
                                      158
<PAGE>
 
form and will not be considered the owners or Holders of the Global Note (or
any Notes represented thereby) under the Indenture or the Notes.
 
      The laws of some states require that certain persons take physical
delivery in definitive form of securities that they own. Consequently, the
ability to transfer beneficial interests in a Global Note to such persons may
be limited to that extent. Because DTC can act only on behalf of its
participants, which in turn act on behalf of indirect participants and certain
banks, the ability of a person having beneficial interests in a Global Note to
pledge such interest to persons or entities that do not participate in the DTC
system, or otherwise take actions in respect of such interests, may be affected
by the lack of a physical certificate evidencing such interests.
 
      Payments of the principal of, premium, if any, and interest on Global
Notes will be made to DTC or its nominee as the registered owner thereof.
Neither the Issuer, the Trustee nor any of their respective agents will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interest in the Global Notes
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
      The Issuer expects that DTC or its nominee, upon receipt of any payment
of principal of, premium, if any, or interest in respect of a Global Note
representing any Notes held by it or its nominee, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note for such Notes as shown
on the records of DTC or its nominee. The Issuer also expects that payments by
participants to owners of beneficial interests in such Global Note held through
such participants will be governed by standing instructions and customary
practices, as is now the case with securities held for the accounts of
customers registered in "street name." Such payments will be the responsibility
of such participants. None of the Issuer or the Trustee will be liable for any
delay by DTC or any of its participants in identifying the beneficial owners of
the Notes, and the Issuer and the Trustee may conclusively rely on and will be
protected in relying on instructions from DTC or its nominee as the registered
owner of the Notes for all purposes.
 
      Interests in the Global Notes will trade in DTC's Same-Day Funds
Settlement System and secondary market trading activity in such interests will
therefore settle in immediately available funds, subject in all cases to the
rules and procedures of DTC and its participants. Transfers between
participants in DTC will be effected in accordance with DTC's procedures, and
will be settled in same-day funds.
 
      DTC has advised the Issuer that it will take any action permitted to be
taken by a holder of Notes only at the direction of one or more participants to
whose accounts with DTC interests in the Global Notes are credited and only in
respect of such portion of the aggregate principal amount of the Notes as to
which such participant or participants has or have given such direction.
However, if there is an Event of Default under the Notes, DTC reserves the
right to exchange the Global Notes for Notes in certificated form, and to
distribute such Notes to its participants.
 
      Although DTC has agreed to the foregoing procedures in order to
facilitate transfer of beneficial ownership interests in the Global Notes among
participants of DTC, it is under no obligation to perform or continue to
perform such procedures, and such procedures may be discontinued at any time.
None of the Issuer, the Trustee nor any of their respective agents will have
any responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing its operations, including maintaining, supervising or reviewing the
records relating to or payments made on account of, beneficial ownership
interests in Global Notes.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
      The following summary describes certain United States federal income tax
consequences of the exchange of Old Notes for New Notes as of the date hereof.
The discussion below is based upon the provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), and regulations, rulings and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified so as to result in federal income tax
consequences different from those discussed below. Persons considering the
exchange of Old Notes for New Notes should consult their own tax advisors
concerning the federal income tax consequences in light of their particular
situations as well as any consequences arising under the laws of any other
taxing jurisdiction.
 
Exchange of Notes
 
      The exchange of Old Notes for New Notes pursuant to the Exchange Offer
should not be treated as an "exchange" for federal income tax purposes, because
the New Notes should not be considered to differ materially in kind or extent
from the Old Notes. Rather, the New Notes received by a holder of Old Notes
should be treated as a continuation of the Old Notes in the hands of such
holder. As a result, there should be no federal income tax consequences to a
holder exchanging Old Notes for New Notes pursuant to the Exchange Offer.
 
                              PLAN OF DISTRIBUTION
 
      Each broker-dealer that receives New Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that, for a
period of 90 days after the Expiration Date, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. In
addition, for a period of 90 days after the Expiration Date, all dealers
effecting transactions in the New Notes may be required to deliver a
Prospectus.
 
      The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or at negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from any
such broker-dealer and/or the purchasers of any such New Notes. Any broker-
dealer that resells New Notes that were received by it for its own account
pursuant to the Exchange Offer and any broker or dealer that participates in a
distribution of New Notes may be deemed to be an "underwriter" within the
meaning of the Securities Act, and any profit on any such resale of New Notes
and any commissions or concessions received by any such person may be deemed to
be underwriting compensation under the Securities Act. The Letter of
Transmittal states that by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. The Company has no
arrangement or understanding with any broker or dealer to distribute the New
Notes received in the Exchange Offer.
 
      For a period of 90 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.

                (Dollar amounts in thousands except share data)
 
Note 1. Interim Financial Statements
 
      In the opinion of management, the accompanying interim unaudited
consolidated financial statements contain all adjustments (consisting only of
normal recurring accruals) necessary to present fairly the consolidated
financial position of Centennial Cellular Corp. and Subsidiaries (the
"Company") as of November 30, 1998 and the results of its consolidated
operations and cash flows for the periods ended November 30, 1998 and 1997.
These financial statements do not include all disclosures required by
generally accepted accounting principles. The statements should be read in
conjunction with the consolidated financial statements and notes thereto
included in the Company's May 31, 1998 Annual Report on Form 10-K, which
includes a summary of significant accounting policies and other disclosures.
The consolidated balance sheet at May 31, 1998 is audited.
 
Reclassifications
 
      Certain prior period balances have been reclassified to conform with the
current period presentation.
 
Note 2. Agreement and Plan of Merger
 
      On November 29, 1998, the Company and CCW Acquisition Corp.
("Acquisition"), a Delaware corporation organized at the direction of Welsh,
Carson, Anderson & Stowe VIII, L.P. ("WCAS VIII"), executed an Amendment to
the Agreement and Plan of Merger, dated as of July 2, 1998 (as amended, the
"Merger Agreement"), providing for the merger of Acquisition with and into
Centennial (the "Merger"). The Company expects to close the Merger in January
1999. Centennial will continue as the surviving corporation (the "Surviving
Corporation") in the Merger.
 
      Subject to the effects of proration, in the Merger, outstanding shares
of Class A Common Stock ("Class A Common Stock") will be converted into the
right to receive $41.50 per share in cash or to receive common shares of the
Surviving Corporation (the "Surviving Corporation Shares") representing up to
7.1% of the Surviving Corporation Shares outstanding immediately after the
Merger. Outstanding shares of Class B Common Stock ("Class B Common Stock")
will be converted into the right to receive $41.50 per share in cash;
provided, that if the aggregate number of Surviving Corporation Shares elected
to be received by holders of Class A Common Stock is less than 7.1% of the
common shares of the Surviving Corporation outstanding immediately after the
Merger, then a number of shares of Class B Common Stock equal to a portion of
such shortfall will be converted into Surviving Corporation Shares on a pro
rata basis with shares of Class A Common Stock with respect to which an
election to receive Surviving Corporation Shares has not been made. All
outstanding shares of Convertible Redeemable Preferred Stock (the "Convertible
Redeemable Preferred Stock") and Second Series Convertible Redeemable
Preferred Stock (the "Second Series Convertible Redeemable Preferred Stock"
and, together with the Convertible Redeemable Preferred Stock, the "Preferred
Stock") will be converted into the right to receive $41.50 per share in cash
on an as-converted basis.
 
      Because existing holders of common stock of the Company must receive in
the Merger an amount of Surviving Corporation Shares equal to 7.1% of the
common shares of the Surviving Corporation outstanding immediately after the
effective time of the Merger (the "Effective Time"), holders of Class A Common
Stock who do not elect to receive any shares and holders of Class B Common
Stock may, due to proration, be required to receive some Surviving Corporation
Shares. In addition, holders of Class A Common Stock who elect to receive
shares may, due to proration, receive Surviving Corporation Shares and receive
cash in amounts which vary from the amounts such holders elected.

                (Dollar amounts in thousands except share data)
 
 
      Pursuant to the Merger Agreement, it is anticipated that each option to
purchase shares of Class A Common Stock (an "Option") granted under the
Company's 1991 Employee Stock Option Plan and Non-Employee/Officer Director
Option Plan, as amended (collectively, the "Option Plans") will be exercised or
canceled pursuant to its terms or canceled in exchange for a cash amount equal
to the difference between $41.50 and the exercise price of the Option prior to
the Effective Time. Each Option that is not exercised or canceled will remain
outstanding immediately following the Effective Time and such Options will be
subject to adjustment pursuant to the terms of the Option Plans.
 
      In connection with the execution of the Merger Agreement, Century
Communications Corp. ("Century"), the Company's principal stockholder, entered
into a Stockholder Agreement, dated as of July 2, 1998, with Acquisition (the
"Stockholder Agreement"). Pursuant to the Stockholder Agreement, Century, which
has an approximate 33% Common Stock interest and, through its beneficial
ownership of approximately 81.2% of the Company's outstanding Class B Common
Stock, which has disproportionate votes per share (15 votes per share), an
approximate 74% voting interest in the Company as of November 30, 1998, agreed
to vote its shares in favor of the Merger so long as the Merger Agreement
remains in effect. Because Century agreed to approve the Merger by written
consent in lieu of meeting, and controls, on a fully diluted basis, more than a
majority of the outstanding votes of the Company required to approve the
Merger, no further vote was necessary to approve the Merger. On December 4,
1998, Century executed a written stockholder's consent in lieu of meeting to
approve the Merger.
 
      Pursuant to the Merger Agreement, from the date of the Merger Agreement
to the Effective Time, the Company shall conduct its business in the ordinary
course consistent with past practice and shall use reasonable efforts to
preserve intact its business organizations and relationships with third parties
and to keep available the services of its present officers and key employees.
All statements contained in this Quarterly Report, including discussions of the
Company's plans and strategies, are subject to the Company's covenants
regarding the conduct of its business pending the Merger.
 
      On December 8, 1998, the Company's Registration Statement on Form S-4
with respect to the issuance of common stock of the Company, as the Surviving
Corporation in the Merger, was declared effective by the Securities and
Exchange Commission (the "SEC"). Upon consummation of the Merger, such common
stock of the Surviving Corporation will be received by (i) current holders of
Class A Common Stock who make an effective election to receive such shares,
(ii) by current holders of Class A Common Stock with respect to which an
election to receive Surviving Corporation Shares has not been made who are
required to receive such shares due to proration or (iii) by current holders of
Class B Common Stock who are required to receive such shares due to proration.
A holder of Class A Common Stock electing to receive Surviving Corporation
Shares must make an election by 5:00 p.m., New York City time, on January 6,
1999.
 
      The consummation of the Merger is subject to certain conditions,
including, without limitation, the funding of committed financing, which
financing is no longer subject to any material adverse change in relevant
capital markets.
 
      Whether or not the Merger is consummated, all costs and expenses incurred
in connection with the Merger, the Merger Agreement and the transactions
contemplated by the Merger Agreement shall be paid by the party incurring such
expenses. However, in the event the Company or Acquisition shall have
terminated the Merger Agreement as a result of either the Company entering into
a definitive written agreement with respect to any merger, consolidation or
other business combination, tender or exchange offer, recapitalization

transaction, asset or stock purchase or other similar transaction with a third
party (an "Acquisition Transaction") or the Board of Directors of the Company
having withdrawn, modified or amended in any manner adverse to Acquisition or
the stockholders of Acquisition its approval or recommendation of the Merger
Agreement or approved, recommended or endorsed any proposal for an Acquisition
Transaction, then the Company shall simultaneously reimburse Acquisition for
documented fees and expenses (subject to a maximum of $25,000) and pay
Acquisition a termination fee of $40,000.
 
      In connection with the Merger, Acquisition has received a commitment from
third parties for financing for Acquisition and certain existing and future
subsidiaries of the Company in the aggregate amount of approximately $1,050,000
in the form of a senior secured credit facility. Additionally, an affiliate of
WCAS VIII has agreed to purchase approximately $180,000 aggregate amount of
unsecured subordinated notes of the Surviving Corporation. Finally, WCAS VIII
and other equity investors have agreed to purchase approximately $400,000 of
common stock of the Surviving Corporation. It is anticipated that this funding
will be used to pay the merger consideration described above, repay or
repurchase certain indebtedness of the Company and pay related fees and
expenses. Additionally, pursuant to the Merger Agreement, the Company has
agreed that, upon the request of Acquisition, it will commence offers to
repurchase its two outstanding issuances of public debt (the "Debt Offers").
Pursuant to the Merger Agreement and at the request of Acquisition, the Company
commenced the Debt Offers and consent solicitations with respect to these two
public debt issuances on September 8, 1998. The Company has extended the
expiration date for the Debt Offers to January 6, 1999. Through December 16,
1998, over 99% of the Company's public debt was tendered and consents were
delivered to the Company. As a condition to the closing of the Merger, the
Company must complete the Debt Offers for its two public debt issuances of
$350,000 in the aggregate, prior to the closing date of the Merger. The final
cost to the Company of the redemption, including accrued interest, is
approximately $398,000. The Company's obligation to accept for purchase, and to
pay for, the public debt validly tendered is subject to certain conditions,
including the consummation of the Merger, which, in turn, is subject to certain
other conditions.
 
      Acquisition notified the Company that on December 14, 1998, as part of
the financing necessary to effect the Merger, a corporation formed in
connection with the Merger, which will be a subsidiary of the Surviving
Corporation following the Merger, issued $370,000 of senior subordinated debt
securities to qualified institutional buyers under a private placement offering
pursuant to Rule 144A and Regulation S of the Securities Act of 1933, as
amended. There can be no assurance that Acquisition will receive the other
funding referred to above and, in the event that Acquisition must seek
alternative financing to consummate the Merger, there can be no assurance that
it will be able to secure alternative financing on terms no less favorable than
the terms of the above commitments. Additionally, there can be no assurance
that the Debt Offers will be consummated.
 
      The accompanying consolidated financial statements have been prepared on
a historical basis and do not include any adjustments relating to the Merger
Agreement.

      Centennial Puerto Rico Wireless Corporation, a wholly owned subsidiary of

CPRW, on (a) the Base Rate, as defined, plus a margin of 1.50% or (b) the
Eurodollar Base Rate, as defined, plus a margin of 2.50%, adjusted for the
maintenance of certain specified ratios, as applicable.
 
      As of November 30, 1998, no amounts were outstanding under the Company's
$75,000 domestic revolving credit facility (the "Domestic Credit Facility").
The commitment available under the Domestic Credit Facility terminates on

Note 4. Dispositions
 
      On June 8, 1998, the Company disposed of its investment interest in the
Coconino, Arizona RSA, representing approximately 43,500 Net Pops, for $13,500
in cash. The Company recorded a pre-tax gain of $9,556 in relation to the sale
of this investment interest during the three months ended August 31, 1998.
 
Note 5. Revenue Recognition
 
      Wireless telephone service income includes earned subscriber service
revenue and charges for installation and connections, net of associated roaming
costs of $23,556 and $18,026 for the six months ended November 30, 1998 and
1997, respectively.
 
Note 6. Income (Loss) per Common Share
 
      The Company applies the provisions of Statement of Financial Accounting
Standards No. 128, "Earnings Per Share" ("SFAS 128"). Under SFAS 128, Basic
earnings per share ("EPS") is calculated by dividing income (loss) applicable
to common shares by weighted average common shares outstanding. Diluted EPS
reflects the potential dilution that could occur if potential common stock
instruments of the Company were exercised, converted or issued.
 
Note 7. Commitments and Contingencies
 
      The Company is controlled by Century. Century has an approximately 33%
common stock interest and, through ownership of the Company's Class B Common
Stock which has disproportionate votes per share (15 votes per share), an
approximate 74% voting interest in the Company as of November 30, 1998. The
Company and Century entered into a Services Agreement, effective August 30,
1996 (the "Services Agreement"), pursuant to which Century, through its
personnel, provides design, construction, management, operational, technical
and maintenance services for the wireless telephone, paging and related systems
owned and operated by the Company. Such services also include providing all the
services necessary for the monitoring, to the extent possible, of the
activities of the partnerships in which the Company has minority equity
interests in such manner as to protect the interests of the Company. Such
services have historically been provided to the Company by Century. As
consideration for the services rendered and to be rendered under the Services
Agreement, the Company pays Century the annual sum of $1,000 and reimburses
Century for all costs incurred by Century or its affiliates (excluding the
Company and its subsidiaries) that are directly attributable to the design,
construction, management, operation and maintenance of the wireless telephone,
paging and related systems of the Company or to the performance by Century of
its other duties under the Services Agreement. For the six months ended
November 30, 1998, the Company has recorded expenses of $500 under the Services
Agreement of which $250 is recorded within payable to affiliate on the
Company's consolidated balance sheet at November 30, 1998. Century has entered

      In September 1998, the Commonwealth of Puerto Rico sustained damage as a
result of the effects of Hurricane Georges. The Company has evaluated the
extent of damage to its Puerto Rico network infrastructure and the impact the
Hurricane has had on the Company's Puerto Rico service revenue during the
second quarter ended November 30, 1998. After consideration of expected
insurance recoveries, the Company believes it will not incur significant losses
as a result of the effects of the damage caused by Hurricane Georges. During
the three months ended November 30, 1998, the Company recorded approximately
$1,600 of insurance recoveries related to subscriber refunds within revenue.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholders
Centennial Cellular Corp.
New Canaan, Connecticut
 
      We have audited the accompanying consolidated balance sheets of
Centennial Cellular Corp. and Subsidiaries as of May 31, 1998 and 1997, and the
related consolidated statements of operations, common stockholders' equity and
cash flows for each of the three years in the period ended May 31, 1998. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatements. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
      In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Centennial Cellular Corp. and

1. SIGNIFICANT ACCOUNTING POLICIES
 
      Description of business--Centennial Cellular Corp. ("Centennial" and
together with its subsidiaries and partnership interests, the "Company")
operates wireless telephone systems which produce high quality, high capacity
communications to and from vehicle-installed, ready-to-carry and hand-held
wireless telephones ("wireless telephones"). Wireless telephone systems are
designed to allow for mobility of the subscriber. In addition to mobility,
wireless telephone systems provide access through system interconnections to
local and long distance telecommunications networks and offer other ancillary
services such as voice mail, call waiting, call forwarding and conference
calling. These communications services can be integrated with a variety of
competing networks. Wireless telephone service is provided to subscribers
through a variety of price plans, the most common being a monthly fixed charge
plus additional variable charges per minute of airtime used.
 
      The Company operates and invests in wireless telephone systems in the
United States (the "Domestic Wireless Telephone Systems" or "Domestic
Wireless") and on December 12, 1996 the Company began providing wireless
telephone service in Puerto Rico (the "Puerto Rico Wireless Telephone System"
or "Puerto Rico Wireless"). The Company operates its Domestic Wireless
Telephone Systems pursuant to 29 cellular licenses which it owns. The Company
operates its Puerto Rico Wireless Telephone System pursuant to a Major Trading
Area ("MTA") Personal Communications Service ("PCS") license to provide
broadband PCS in the Commonwealth of Puerto Rico and the U.S. Virgin Islands.
The Company also participates in the alternative access business in Puerto Rico
pursuant to the Federal Communications Commission's requirements for interstate
service and pursuant to an authorization issued to Puerto Rico Wireless in
December 1994 by the Public Service Commission of the Commonwealth of Puerto
Rico for intrastate service. Puerto Rico Wireless began providing competitive
alternative access service in September 1997.
 
      Principles of consolidation--The consolidated financial statements
include the accounts of the Company and all of its subsidiaries and partnership
interests from their respective incorporation or acquisition dates. All
material intercompany transactions and balances have been eliminated.
 
      Property, plant and equipment--Property, plant and equipment is stated at
cost. Depreciation is computed by the straight-line method over the estimated
useful lives of the assets:
 
<TABLE>
       <S>                                                         <C>
       Wireless telephone transmission and distribution systems
        and related equipment.....................................   10 years
       Miscellaneous equipment and furniture and fixtures......... 5-15 years
       PCS phones.................................................  18 months
</TABLE>
 
      Cellular telephone and personal communications service licenses--Licenses
consist of amounts allocated under purchase accounting from the purchase price
of acquired assets. Cellular telephone licenses are amortized over a ten-year
life using the straight-line method. The PCS license is being amortized over a
forty-year life using the straight line method commencing with the date of
operations, December 12, 1996 (See Valuation of long lived assets). During the
fiscal years ended May 31, 1997 and 1996, the Company capitalized interest
costs of $2,752 and $5,200, respectively, related to the acquisition of the PCS
license. During 1998, no interest was capitalized.
 
      Equity investments in wireless systems--The Company records such
investments at purchased cost at the date of acquisition and adjusts for the
Company's share of net income or loss from the acquisition date. The difference
between the cost of such investment and the underlying book value of $123,024
is amortized over ten years (See Note 7).

                   CENTENNIAL CELLULAR CORP. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                    Years Ended May 31, 1998, 1997 and 1996
            (Amounts in thousands, except subscriber and share data)
 
      Goodwill--The excess of purchase price over the estimated fair value of
tangible and intangible net assets acquired is being amortized using the
straight-line method over 40 years (See Valuation of long lived assets).
 
      Other Assets--Included in other assets at May 31, 1998 is a $6,000
deferred charge, net of accumulated amortization of $350, which represent
certain costs incurred by the Company in relation to the Facilities Agreement
with Century-ML dated January 2, 1995 (the "Facilities Agreement") (See Note 9
"Transactions with Affiliated Companies"). These costs are being amortized over
the life of the Facilities Agreement (25 years).
 
      Income taxes--The Company accounts for income taxes in accordance with
Financial Accounting Standards No. 109, "Accounting for Income Taxes" which
provides that the deferred tax provision is determined by the liability method.
Deferred tax assets and liabilities are recognized based on the differences
between the book and tax basis of assets and liabilities using presently
enacted tax rates.
 
      Loss per common share--Effective with the quarter ended February 28,
1998, the Company adopted the provisions of Statement of Financial Accounting
Standards No. 128, "Earnings Per Share" ("SFAS 128"), which is effective for
financial statements ending after December 15, 1997. This statement supersedes
Accounting Principles Board Opinion No. 15 ("APB15") and replaces the
presentation of primary earnings per share ("EPS") and fully diluted EPS on the
face of the statement of operations with basic and diluted EPS. Basic EPS is
calculated by dividing loss applicable to common shares by weighted average
common shares outstanding. Diluted EPS reflects the potential dilution that
could occur if potential common stock instruments of the Company were
exercised, converted or issued. Adoption of SFAS 128 did not result in a change
of EPS previously reported by the Company using APB 15.
 
      Revenue recognition--Wireless telephone service income includes earned
subscriber service revenues and charges for installations and connections, net
of associated roaming costs of $36,769, $28,049, and $20,000, in 1998, 1997 and
1996, respectively. Subscriber services paid in advance are recognized as
income when earned.
 
      Valuation of long lived assets--The Company, on a quarterly basis,
undertakes a review and valuation of the net carrying value, recoverability and
write-off period of all categories of its long lived assets. The Company in its
valuation considers current market values of wireless properties, competition,
prevailing economic conditions, government policy including taxation and the
Company's and the industry's historical and current growth patterns. The
Company also considers its financial structure including the underlying cost of
the securities which support the Company's internal growth and acquisitions, as
well as the recoverability of the cost of its long lived assets based on a
comparison of estimated undiscounted operating cash flows for the systems which
generated long lived assets with the carrying value of the long lived assets.
 
      Management estimates--The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses
during the reporting periods. Actual results could differ from those estimates.
 
      Disclosure of fair value of financial instruments--The carrying amounts
reported in the balance sheets for cash and cash equivalents, accounts
receivable, accounts payable and accrued expenses approximates fair value
because of the immediate short-term maturity of these financial instruments.
The carrying amounts of the Company's credit facilities approximate their fair
values because of their variable interest rates.

            (Amounts in thousands, except subscriber and share data)
 
      Statement of cash flows--Short-term investments classified as cash
equivalents in the consolidated financial statements consist principally of
overnight deposits and commerical paper with acquired maturities of three
months or less.
 
      Reclassifications--Certain prior year balances have been reclassified to
conform with the current year presentation.
 
      New Accounting pronouncements--The Financial Accounting Standards Board
issued Statement of Financial Accounting Standards No. 129, "Disclosure of
Information about Capital Structure", Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income," and Statement of Financial
Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and
Related Information" in 1997, and Statement of Financial Accounting Standards
No. 132, "Employers' Disclosures about Pensions and Other Postretirement
Benefits" and Statement of Financial Accounting Standards No. 133, "Accounting
for Derivative Instruments and Hedging Activities" in 1998. Additionally,
during 1998, the AICPA's Accounting Standards Executive Committee issued
Statement of Position (SOP) 98-5 "Reporting on the Cost of Start-Up
Activities". The Company believes these statements will not have a material
impact on the Consolidated Financial Statements of the Company when adopted.
 
2. AGREEMENT AND PLAN OF MERGER
 
      On July 2, 1998, the Company and CCW Acquisition Corp. ("Acquisition"), a
Delaware corporation organized at the direction of Welsh, Carson, Anderson &
Stowe VIII, L.P. ("WCAS VIII"), entered into an Agreement and Plan of Merger
(the "Merger Agreement") providing for the merger of Acquisition with and into
Centennial (the "Merger"). Centennial will continue as the surviving
corporation (the "Surviving Corporation") in the Merger.
 
      Subject to proration, pursuant to the Merger Agreement, outstanding Class
A Common Stock ("Class A Common Stock") will be converted into the right to
receive $43.50 per share in cash or to retain up to 7.1% of the common stock of
the Surviving Corporation outstanding after the Merger. Class B Common Stock
("Class B Common Stock") will be converted into the right to receive $43.50 per
share in cash; provided, that if the aggregate number of shares of Class A
Common Stock elected to be retained by Centennial's existing stockholders is
less than 7.1% of the shares outstanding after the Merger, then a number of
shares of Class B Common Stock equal to the pro rata portion of such shortfall
will be converted into shares of Class A Common Stock and retained. All
outstanding Convertible Redeemable Preferred Stock (the "Convertible Redeemable
Preferred Stock") and Second Series Convertible Redeemable Preferred Stock (the
"Second Series Convertible Redeemable Preferred Stock" and, together with the
Convertible Redeemable Preferred Stock, the "Redeemable Preferred Stock") will
be converted into the right to receive $43.50 per share in cash on an as
converted basis. (See Note 12 to the Company's Consolidated Financial
Statements).
 
      Because 7.1% of the shares outstanding immediately after the effective
time of the Merger (the "Effective Time") must be retained by such existing
stockholders of the Company in the Merger, stockholders who do not elect to
retain any shares may, due to proration, be required to retain some Common
Stock. In addition, stockholders who elect to retain shares may, due to
proration, retain Common Stock and receive cash in amounts which vary from the
amounts such holders elected.
 
      Pursuant to the Merger Agreement, it is anticipated that each option to
purchase Class A Shares (an "Option") granted under the Company's 1991 Employee
Stock Option Plan and Non-Employee/Officer
 
                                      F-22

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                    Years Ended May 31, 1998, 1997 and 1996
            (Amounts in thousands, except subscriber and share data)
Director Option Plan, as amended (collectively, the "Option Plans") will be
exercised or canceled pursuant to its terms or in exchange for a cash amount
equal to the difference between $43.50 and the exercise price of the Option
prior to the Effective Time. Each Option that is not exercised or canceled will
remain outstanding immediately following the Effective Time and such Options
will be subject to adjustment pursuant to the terms of the Option Plans.
 
      In connection with the execution of the Merger Agreement, Century
Communications Corp. ("Century"), the Company's principal stockholder, entered
into a Stockholder Agreement, dated July 2, 1998, with Acquisition (the
"Stockholder Agreement"). Pursuant to the Stockholder Agreement, Century, which
has an approximate 34% Common Stock interest and, through ownership of the
Company's Class B Common Stock which has disproportionate votes per share (15
votes per share), an approximate 74% voting interest in the Company at May 31,
1998, agreed to vote its shares in favor of the approval and adoption of the
Merger Agreement. Because Century agreed to approve the Merger by written
consent, consummation of the Merger does not require approval by a majority of
the Company's stockholders who are not affiliated with the Company or
Acquisition.
 
      Pursuant to the Merger Agreement, from the date of the Merger Agreement
to the Effective Time, the Company shall conduct its business in the ordinary
course consistent with past practice and shall use reasonable efforts to
preserve intact its business organizations and relationships with third parties
and to keep available the services of its present officers and key employees.
All statements contained in this Annual Report, including discussions of the
Company's plans and strategies, are subject to the Company's covenants
regarding the conduct of its business pending the Merger.
 
      The consummation of the Merger is subject to certain conditions,
including, without limitation, the Company obtaining a final order from the
Federal Communications Commission (the "FCC") approving the transfer of control
of the Company to WCAS VIII and its affiliates, the expiration of antitrust
regulatory waiting periods and Acquisition obtaining financing substantially on
the terms contemplated by the commitment letters it received in connection with
the Merger Agreement.
 
      Whether or not the Merger is consummated, all costs and expenses incurred
in connection with the Merger, the Merger Agreement and the transactions
contemplated by the Merger Agreement shall be paid by the party incurring such
expenses. However, in the event the Company or Acquisition shall have
terminated the Merger Agreement as a result of either the Company entering into
a definitive written agreement with respect to any merger, consolidation or
other business combination, tender or exchange offer, recapitalization
transaction, asset or stock purchase or other similar transaction with a third
party (an "Acquisition Transaction") or the Board of Directors of the Company
having withdrawn, modified or amended in any manner adverse to Acquisition its
approval or recommendation of the Merger Agreement or approved, recommended or
endorsed any proposal for an Acquisition Transaction, then the Company shall
reimburse Acquisition for documented fees and expenses (subject to a maximum of
$25.0 million) and pay Acquisition a termination fee of $40 million.
 
      In connection with the Merger, Acquisition has received a commitment from
a third party for financing for Acquisition and certain existing and future
subsidiaries of the Company in the aggregate amount of approximately $1.6
billion in the form of senior secured credit facilities and an unsecured bridge
loan. Additionally, an affiliate of WCAS VIII has agreed to purchase
approximately $150 million aggregate amount of subordinated notes of the
Surviving Corporation. Finally, WCAS VIII and other equity investors have
agreed

            (Amounts in thousands, except subscriber and share data)
to purchase approximately $350 million of common stock of the Surviving
Corporation. It is anticipated that this funding will be used to pay the merger
consideration described above and related fees and expenses. Additionally,
pursuant to the Merger Agreement, the Company has agreed that, upon the request
of Acquisition, it will commence offers to repurchase its two outstanding
issuances of public debt (the "Debt Offers"). As a condition to the closing of
the Merger, the Company must consummate the Debt Offers prior to the closing
date of the Merger. There can be no assurance that Acquisition will receive the
funding referred to above or, if it does receive such funding, there can be no
assurance as to the timing or terms thereof. Additionally, there can be no
assurance that the Debt Offers will be consummated. Finally, in the event that
Acquisition must seek alternative financing to consummate the Merger there can
be no assurance that it will be able to secure alternative financing on terms
no less favorable than the terms of the above commitments.
 
      The accompanying consolidated financial statements have been prepared on
a historical basis and do not include any adjustments relating to the Agreement
and Plan of Merger.
 
3. SUPPLEMENTAL DISCLOSURE OF NON-CASH INVESTING AND FINANCING ACTIVITIES
 
      In connection with the completion of the acquisitions made during the
year ended May 31, 1996, the Company recorded approximately $9,120 in goodwill
and in deferred income taxes, resulting from differences between the book and
tax basis of certain assets acquired (See Note 4).
 
      During the year ended May 31, 1996, the Company reclassified $2,774 of
property, plant and equipment, $2,801 of goodwill, $160 of other assets, $476
of accounts receivable and $672 of accounts payable to cellular telephone
license as a result of the exchange of cellular markets described in Note 4.
 
4. ACQUISITIONS/EXCHANGES/DISPOSITIONS
 
      On June 8, 1998, the Company disposed of its investment interest in the
Coconino, Arizona RSA, representing approximately 43,500 Net Pops, for $13,500
in cash. During the first quarter of fiscal 1999, the Company recorded a pre-
tax gain of approximately $9,500 in relation to the sale of this investment
interest.
 
      During the three years ended May 31, 1998, the Company
acquired/exchanged/sold the net assets and interests in wireless telephone and
PCS licenses as follows:

      On November 15, 1993, the Company issued $250,000 of eight-year unsecured
Senior Notes (the "8 7/8% Notes"). The interest on the 8 7/8% Notes is payable
semi-annually at an interest rate of 8 7/8%. The interest is computed on the
basis of a 360-day year (twelve 30 day months). The maturity date of the 8 7/8%
Notes is November 1, 2001 unless redeemed earlier at the option of the Company,
however not prior to May 1, 1999. If early redemption is sought during the
twelve-month period beginning May 1 of each of the following years, the
redemption price is calculated using:

      Costs associated with the bond offering of $4,898 were capitalized and
are being amortized on a straight-line basis over the life of the issue. At May
31, 1998 and 1997, the 8 7/8% Notes were trading at 104.01% and 99.47% of par
or $260,025 and $248,675, respectively.
 
      On May 11, 1995, the Company issued $100,000 of ten-year unsecured Senior
Notes (the "10 1/8% Notes"). The interest on the 10 1/8% Notes is payable semi-
annually on the basis of a 360-day year (twelve 30 day months). The 10 1/8%
Notes rank "pari passu" with the Company's 8 7/8% Notes and may not be redeemed
prior to maturity on May 15, 2005. Costs associated with the May 11, 1995 bond
offering of approximately $4,614 were capitalized and are being amortized on a
straight-line basis over the life of the issue. At May 31, 1998 and 1997, the
notes were trading at 110.87% and 104.25% of par or $110,870 and $104,250,

      Centennial Puerto Rico Wireless Corporation, a wholly owned subsidiary of
the Company ("CPRW"), has a four-year $180,000 revolving credit facility, as
amended, (the "Puerto Rico Credit Facility"). As of May 31, 1998, the Puerto
Rico Credit Facility had $150,000 outstanding. The interest rate payable by
CPRW on borrowings under the Puerto Rico Credit Facility is based, at the
election of CPRW, on (a) the Base Rate, as defined, plus a margin of 1.50% or
(b) the Eurodollar Base Rate, as defined, plus a margin of 2.50%, adjusted for
the maintenance of certain specified ratios, as applicable. The Puerto Rico
Credit Facility, which is nonrecourse to the Company, is secured by
substantially all of the assets of CPRW and its direct and indirect
subsidiaries.
 
      As of May 31, 1998, the Company had $10,000 outstanding under its $75,000
domestic revolving credit facility (the "Domestic Credit Facility"). The
interest rate payable on the Domestic Credit Facility is based, at the election
of the Company, on (a) the Base Rate,as defined, plus a margin of 2% or (b) the
Eurodollar Base Rate, as defined, plus a margin of 3%. The Domestic Credit
Facility is secured by the pledge of the stock of certain of the Company's
subsidiaries, and is further guaranteed by certain subsidiaries holding
investment interests.
 
      The Domestic Credit Facility, the Puerto Rico Credit Facility and the
Company's public debt instruments require the maintenance of certain financial
and operating covenants, restrict the use of borrowing, limit the incurrence of
additional indebtedness and limit the ability to pay dividends and management
fees. The Company and CPRW were in compliance with all covenants of their debt
instruments at May 31, 1998.
 
9. TRANSACTIONS WITH AFFILIATED COMPANIES
 
      The Company and Century Communications Corp. ("Century"), owner of
approximately 34% of Centennial's common stock, currently maintain combined
workers compensation and general insurance policies. The premiums are allocated
between the Company and Century based upon the actual cost of each respective
company's coverage. The Company believes that the amounts payable by the
Company under such arrangement are more favorable than the premiums the Company
would pay if it were to obtain coverage under a separate policy. The Company's
cost of such insurance was approximately $624, $727 and $1,688 for the fiscal
years ended May 31, 1998, 1997 and 1996 respectively, all of which was paid in
full during the current fiscal year. In fiscal 1996 the Company and Century
also maintained combined group health, life and casualty coverage.
 
      The Company is controlled by Century. Century has an approximate 34%
common stock interest and, through ownership of the Company's Class B Common
Stock which has disproportionate votes per share (15 votes per share), an
approximate 74% voting interest in the Company at May 31, 1998. The Company and

            (Amounts in thousands, except subscriber and share data)
Century entered into a Services Agreement, effective August 30, 1996 (the
"Services Agreement"), pursuant to which Century, through its personnel,
provides design, construction, management, operational, technical and
maintenance for the wireless telephone, paging and related systems owned and
operated by the Company. Such services also include providing all the services
necessary for the monitoring, to the extent possible, of the activities of the
partnerships in which the Company has minority equity interests, in such manner
as to protect the interests of the Company. Such services have historically
been provided to the Company by Century. As consideration for the services
rendered and to be rendered under the Services Agreement, the Company pays
Century the annual sum of $1,000 and reimburses Century for all costs incurred
by Century or its affiliates (excluding the Company and its subsidiaries) that
are directly attributable to the design, construction, management, operation
and maintenance of the wireless telephone, paging and related systems of the
Company or to the performance by Century of its other duties under the Services
Agreement. For the year ended May 31, 1998 and 1997, the Company recorded
expenses of $1,000 and $750, respectively, under the Services Agreement. At May
31, 1998 and 1997, $250 and $750, respectively, of such amounts were recorded
within Payable to Affiliate on the Company's consolidated balance sheet.
Century has entered into an agreement with CCW Acquisition Corp. pursuant to
which it has agreed to terminate the Services Agreement as of the effective
time of the Merger.
 
      The Company leases space for the mobile telephone switching office
("MTSO") serving the southwestern cluster and space on an antenna tower in the
southwestern cluster from Century for an aggregate current annual rent of
approximately $1 pursuant to an oral month to month lease agreement. Further,
the Company leases certain warehouse space in Puerto Rico to Century-ML for a
current annual rent of approximately $23 pursuant to a written lease agreement.
The Company leases and shares capacity on the fiber optic cable television
facility and network of Century-ML for the purpose of operating as a
competitive access provider. The Company shares in the cost of construction,
operation and maintenance of the Century-ML fiber network on a pro rata basis
based on the percentage of the number of fibers of the network used by or
reserved for the Company.
 
      During fiscal 1997, the Company recorded a deferred asset and related
payable to an affiliate in its consolidated balance sheet in the amount of
$6,000 to reflect certain costs incurred by the Company to secure the use of
the fiber optic network as required by the Facilities Agreement. This amount,
which was paid by the Company during fiscal 1998, represents the Company's
share of the costs of constructing Century-ML's fiber optic network. (See Note
1).
 
      Leavy Rosensweig & Hyman, of which David Z. Rosensweig, a director and
Secretary of the Company, is a member, serves as general counsel to the Company
and Century. The Company paid approximately $426, $656 and $518, for legal
services to Leavy, Rosensweig & Hyman for the fiscal years ended May 31, 1998,
1997, and 1996, respectively.

      The net deferred tax liabilities at May 31, 1998 and 1997 of $26,584 and
$43,977 respectively, have been classified as non-current deferred income taxes
on the consolidated balance sheet.
 
      At May 31, 1998, the Company and its subsidiaries had approximately
$119,740 of net operating loss carryforwards for federal income tax purposes,
expiring through May 31, 2013, some of which are subject to limitation on their
future utilization under Section 382 of the Internal Revenue Code of 1986.

11. COMMITMENTS AND CONTINGENCIES
 
Equipment and Installation Services
 
      In July 1998, the Company entered into an agreement pursuant to which the
Company has agreed, subject to certain conditions, to purchase equipment and
installation services for its Domestic Wireless Telephone Systems over the next
3 years at a cost of approximately $50,000.
 
Legal Proceedings
 
      There are no material legal proceedings, other than routine litigation
incidental to the business, to which the Company or any of its subsidiaries is
a party to or which any of their property is subject.
 
Pending Acquisitions
 
      The Company plans to exercise, prior to the effective time of the Merger,
its right to acquire the minority interests held by Century Federal Inc., an
affiliate of Century ("Century Federal"), in the Cass and Jackson, Michigan
systems for the prices paid by Century Federal for such minority interests in
the acquisitions of such systems ($2,000 and $1,000, respectively). Upon
completion of these transactions, the Company will own 100% of these systems.

      During the year ended May 31, 1998, the Company directly purchased
1,270,200 shares of its Class A Common Stock in the open market for an
aggregate purchase price of $23,524 pursuant to previous authorizations by the
Company's Board of Directors. These shares have been accounted for as treasury

            (Amounts in thousands, except subscriber and share data)
 
      Shares of Class B common stock are convertible into shares of Class A
common stock on a one-for-one basis.
 
      The Company is restricted from paying dividends on its common stock by
its debt covenants (see Note 8).
 
Preferred Stock
 
      On August 30, 1991, the Company completed a merger (the "1991 Merger")
with Citizens Cellular Company, a wholly-owned subsidiary of Citizens
("Citizens Cellular"). In connection with the 1991 Merger, the Company issued
the Convertible Redeemable Preferred Stock valued at $128,450 and 1,367,099
shares of Class B Common Stock representing 18.8% of the then common equity.
The Convertible Redeemable Preferred Stock is convertible on or after the third
anniversary from the date of issuance into 2,972,335 shares of Class A or B
Common Stock. Although the Convertible Redeemable Preferred Stock carried no
cash dividend requirement through August 30, 1996, the shares accreted
liquidation preference and redemption value at the rate of 7.5% per annum,
compounded quarterly, until then. The fully accreted liquidation preference and
redemption value of such preferred stock at August 30, 1996 was $186,287. The
accretion for the years ended May 31, 1997 and 1996, totaled approximately
$3,475 and $13,080, respectively. Beginning September 1, 1996, the holders of
the Convertible Redeemable Preferred Stock were eligible to receive cash
dividends at the rate of 8.5% per annum, when and as declared by the Board of
Directors of the Company, in its discretion.
 
      In connection with an amendment to the New Services Agreement, which was
entered into in connection with the 1991 Merger, the Company issued to Century
the Second Series Convertible Redeemable Preferred Stock valued at $5,000. The
Second Series Convertible Redeemable Preferred Stock has terms identical to
those of the Convertible Redeemable Preferred stock discussed above. The Second
Series Convertible Redeemable Preferred Stock is convertible on or after the
third anniversary from the date of issuance into 115,710 shares of Class A or B
Common Stock. The fully accreted liquidation preference and redemption value of
such preferred stock at August 30, 1996 was $7,252. The accretion for the years
ended May 31, 1997 and 1996, totaled approximately $135 and $510, respectively.
 
      Assuming no change in the number of shares of such classes outstanding,
the annual dividend that may be declared and made payable, with respect to the
preferred stock is $15,834 and $616, respectively. Both classes of preferred
stock are subject to mandatory redemption in fiscal 2007. Any unpaid dividends
continue to accumulate without additional cost to the Company. During the years
ended May 31, 1998 and 1997, the Company paid quarterly cash dividends with
respect to both classes of preferred stock totaling $12,338 and $8,226,
respectively. The Company will determine, from time to time, the timing,
amount, or distribution (if any) of additional preferred stock dividends.
 
13. COMPENSATION PLANS AND ARRANGEMENTS
 
1991 Employee Stock Option Plan
 
      The Company's 1991 Employee Stock Option Plan (the "Employee Stock Option
Plan") as amended, provides for the grant of options to purchase up to
2,025,000 shares of Class A Common Stock reserved thereunder to directors,
officers and other key employees of the Company. The Employee Stock Option Plan
permits the issuance of "incentive stock options," as defined in Section 422A

1986, as amended (the "Code"), as well as non-qualified stock options and stock
appreciation rights. The Employee Stock Option Plan is administered by the
Employee Stock Option Committee of the Board of Directors which determines the
recipients and provisions of options granted under the Employee Stock Option
Plan, including the option price, term and number of shares subject to option.
The Board of Directors may amend the Employee Stock Option Plan, but the
approval of the stockholders is necessary to increase the total number of
shares that may be issued or transferred under the Employee Stock Option Plan,
to change the minimum purchase price for shares subject to options, to change
the maximum period during which options or stock appreciation rights may be
exercised or to extend the period during which options or stock appreciation
rights may be granted under the Employee Stock Option Plan. Generally, the
option price of incentive and non-statutory stock options granted may be as
determined by the Employee Stock Option Committee, but must be at least equal
to the fair market value of the shares on the date of grant. The maximum term
of each option is ten years.
 
      For any participant who owns shares possessing more than 10% of the
voting rights of the outstanding Common Stock, the exercise price of any
incentive stock option must be at least 110% of the fair market value of the
shares subject to such option on the date of grant and the term of the option
may not be longer than five years. Options become exercisable at such time or
times as the Employee Stock Option Committee may determine when it grants
options. The Employee Stock Option Plan permits the exercise of options by the
payment of cash or delivery of shares of Class A Common Stock equal in fair
market value on the date of exercise to the exercise price. Options granted
under the Employee Stock Option Plan are not transferable by the holder.
 
      Since December 27, 1991, the Company has awarded options to purchase
approximately 2,210,782 shares of Class A Common Stock under the Employee Stock
Option Plan to approximately 215 employees of the Company, including executive
officers and directors. During the fiscal years ended May 31, 1998, 1997 and
1996 the number of such options awarded were approximately 488,000, 925,782,
and 0, respectively. At May 31, 1998, 558,245 options were exercisable.
 
Director Option Plan
 
      The Company's Non-Employee/ Officer Director Option Plan (the "Director
Option Plan") was adopted on October 27, 1993. The Director Option Plan
provides for the grant of non-qualified options to purchase up to 50,000 shares
of Class A Common Stock to non-employee/officer directors, who are not
employees of the Company or its subsidiaries. Options for 1,000 shares of Class
A Common Stock shall be automatically granted under the Director Option Plan on
the date of the annual meeting of shareholders of the Company in each of the
years 1993 through 2002. The Board of Directors may amend the Director Option
Plan, except that the approval of the stockholders is necessary to increase the
total number of shares which may be issued or transferred under the Director
Option Plan, to change the minimum purchase price for shares subject to
options, to change the maximum period during which options may be exercised or
to extend the period during which options may be granted under the Director
Option Plan. Generally, the option price of non-qualified stock options granted
may be as determined by the Director Option Committee, but must be at least
equal to 100% of the fair market value of the shares on the date of the grant.
 
      Options become exercisable at the rate of 20% per year beginning with the
first anniversary of the date of the grant. The Director Option Plan permits
the exercise of options by payments of cash or Class A Common Stock equal in
value to the option price. Options granted under the Director Option Plan are
not transferable by the holder other than by will or the laws of descent and
distribution. During each of the fiscal

1991 Employee Stock Purchase Plan
 
      The Company has reserved 200,000 shares of Class A Common Stock for
issuance under the 1991 Employee Stock Purchase Plan (the "Purchase Plan").
Under the Purchase Plan, eligible employees (which generally includes all full-
time employees of the Company) are able to subscribe for shares of Class A
Common Stock at a purchase price of 85% of the average market price (as
defined) of the Class A Common Stock on the first day or last day of the
payroll deduction period relating to an offering under the Purchase Plan.
Payment of the purchase price of the shares is to be made in installments
through payroll deductions, with no right of prepayment. The Purchase Plan is
administered by the Compensation Committee of the Board of Directors. Rights to
purchase shares of Class A Common Stock under the Purchase Plan may not be
transferred

by the recipient and may be forfeited in the event of the recipient's
termination of employment. As of May 31, 1998, approximately 1,476 employees
and officers of the Company were eligible to participate in the Purchase Plan.
As of May 31, 1998, approximately 35,260 shares were subscribed for under the
Purchase Plan.
 
Equity Incentive Plan
 
      The Company's 1993 Equity Incentive Plan (the "Equity Plan") was adopted
by the Board of Directors and approved by the stockholders on October 27, 1993
and amended on October 29, 1996. The plan permits the issuance of up to 350,000
shares of the Company's Class A Common Stock for high levels of performance and
productivity by officers and other management employees of the Company. The
Equity Plan is administered by the Compensation Committee of the Company's
Board of Directors. The plan authorizes the Committee to grant stock based
awards that include but are not limited to, restricted stock, performance
shares and deferred stock. The Committee determines the recipients and
provisions of the grants under the Equity Plan, including the grant price, term
and number of shares subject to grant.
 
      Generally, any employee will realize compensation taxable as ordinary
income, and the Company will be entitled to a corresponding tax deduction in an
amount equal to the sum of any cash received by the employee plus the fair
market value of any shares of Class A Common Stock received by the employee.
During the fiscal years ended May 31, 1998, 1997 and 1996, the number of
restricted shares issued for awards under the Equity Plan were 131,000, 0 and
82,500. As of May 31, 1998, 216,500 restricted shares were outstanding under
the Equity Plan. The expense reflected in the consolidated financial statements
related to these restricted shares was not material. These restricted shares
vest five years after the date of grant or upon the completion of the Plan of
Merger (See Note 2).
 
      The estimated fair value of options granted during fiscal 1998, 1997 and
1996 were $6.69 per share, $3.49 per share and $5.81 per share, respectively.
The Company applies APB Opinion No. 25 and related interpretations in
accounting for its plans. Accordingly, no compensation cost has been recognized
with respect to its stock option, and stock purchase plans. Had compensation
cost for the Company's stock option plans and stock purchase plan been
determined based on the fair value of the awards on the grant dates in
accordance with the accounting provisions of Statement of Financial Accounting
Standards No. 123 "Accounting for Stock-Based Compensation" ("SFAS 123"), the
Company's net loss and net loss per common share for the years ended May 31,
1998, 1997 and 1996 would have been increased to the pro forma amounts

Incentive Award Plan
 
      The Incentive Award Plan (the "Incentive Plan") permits the grant of
awards to key employees of the Company, which may include employee-directors
and officers, payable in cash or shares of Class A Common Stock. The Company
has reserved 200,000 shares of Class A Common Stock for issuance under the
Incentive Plan. The awards are payable in five to ten equal annual installments
on January 1 of the succeeding years after the grant of the award, provided
that the recipient is an employee on the installment payment date. The
Incentive Plan is administered by the Compensation Committee of the Board of
Directors, which selects the recipients of awards as well as the amount of such
awards and any restriction on such awards. The Board of Directors may amend the
Incentive Plan. Awards granted under the Incentive Plan may not be transferred
by the recipient and may be forfeited in the event of the recipient's
termination of employment. As of May 31, 1998, approximately 1,490 employees,
officers and directors of the Company were eligible to participate in the
Incentive Plan. No awards have been made under the Incentive Plan.
 
1991 Stock Equivalent Plan
 
      The Company's 1991 Stock Equivalent Plan (the "Equivalent Plan") permits
the grant of units of Class A Common Stock Equivalents ("units") to key
employees of the Company, including officers and directors. The Equivalent Plan
is administered by the Compensation Committee of the Board of Directors, which
selects the employees to be granted units, determines the number of units
covered by each grant, determines when units will be granted and the conditions
subject to which any amount may become payable with respect to the units, and
prescribes the form of instruments evidencing units granted under the
Equivalent Plan. Payments for units may be made by the Company in cash or in
shares of Class A Common Stock at the fair market value of the Class A Common
Stock on the date of payment. The Company has reserved 200,000 shares of Class
A Common Stock for issuance under the Equivalent Plan. As of May 31, 1998,
approximately 1,490 employees, officers and directors of the Company were
eligible to participate in the Equivalent Plan. Under the terms of the
Equivalent Plan, the total number of units included in all grants to any
participant may not exceed 10% of the total number of units for which grants
may be made under the Equivalent Plan. Units granted under the Equivalent Plan
are not transferable. As of May 31, 1998, no units had been granted under the
Equivalent Plan.
 
Retirement Plan
 
      Effective January 1, 1994, the Company adopted a 401(k) defined
contribution retirement plan covering employees of its wholly owned
subsidiaries. If a participant decides to contribute, a portion of the
contribution is matched by the Company. Total expense under the plan was
approximately $326, $221, and $134 for the years ended May 31, 1998, 1997, and
1996, respectively.

      We have audited the consolidated financial statements of Centennial
Cellular Corp. and subsidiaries (the "Company") as of May 31, 1998 and 1997 for
each of the three years in the period ended May 31, 1998, and have issued our
report thereon dated July 17, 1998; such report is included elsewhere in this
Form 10-K. Our audits also included the financial statement schedules listed in
Item 14. These financial statement schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion based on our

relation to the basic financial statements taken as a whole, present fairly, in
all material respects, the information set forth therein.

or investigative (other than an action by or in the right of such corporation)
by reason of the fact that such person is or was a director, officer, employee
or agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation or
enterprise. A corporation may indemnify such person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. A Delaware corporation may indemnify officers
and directors in an action by or in the right of the corporation to procure a
judgment in its favor under the same conditions, except that no indemnification
is permitted without judicial approval if the officer or director is adjudged
to be liable to the corporation. Where an officer or director is successful on
the merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses (including attorneys' fees)
which he actually and reasonably incurred in connection therewith. The
indemnification provided is not deemed to be exclusive of any other rights to
which an officer or director may be entitled under any corporation's by-law,
agreement, vote or otherwise.
 
      In accordance with Section 145 of the DGCL, Centennial Cellular Corp.
("Centennial") has adopted a by-law that provides that, to the fullest extent
permitted by DGCL, Centennial shall indemnify any person serving as a director
or officer of Centennial and every such director or officer serving at the
request of Centennial as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise for expenses
incurred in the defense of, or in connection with, any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative. Under Section 145 of the DGCL and Centennial's by-laws, such
indemnification shall not be deemed exclusive of any other rights to which
those seeking indemnification may be entitled under any by-law, agreement, vote
of stockholders or disinterested directors or otherwise, both as to action in
his official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.
 
      Section 18-108 of the Delaware Limited Liability Company Act (the "LLC
Act") empowers a Delaware limited liability company to indemnify and hold
harmless any member or manager or other person from and against any and all
claims and demands whatsoever. In accordance with such section, the limited
liability company agreement of Centennial Cellular Operating Co. LLC
("Centennial Cellular Operating") provides that, to the fullest extent
permitted by the LLC Act, Centennial Cellular Operating shall indemnify a
member, any affiliate of a member, any officers, directors, shareholders,
partners, employees, representatives or agents of a member, or their respective
affiliates, or any employee or agent of Centennial Cellular Operating or its
affiliates (each, a "Covered Person") for any loss, damage or claim incurred by
such Covered Person by reason of any act or omission performed or omitted by
such Covered Person in good faith on behalf of Centennial Cellular Operating
and in a manner reasonably believed to be within such Covered Person's scope of
authority.
 
      Each of Centennial and Centennial Cellular Operating has purchased and
maintains insurance to protect persons entitled to indemnification pursuant to
its by-laws or limited liability company agreement (as the case may be), the
DGCL or the LLC Act against expenses, judgments, fines and amounts paid in
settlement, to the fullest extent permitted by the DGCL or the LLC Act (as the
case may be).

                  debited the amount of cash and the fair market value of
                  property distributed by the Company to such Member (net of
                  liabilities secured by such distributed property which the
                  Member is considered to assume or take subject to under

with Section 704(c) of the Code and the Treasury Regulations thereunder, income,
gain, loss and deduction with respect to any property contributed to the capital
of the Company shall, solely for income tax purposes, be allocated among the
Members so as to take account of any variation between the adjusted basis of
such property to the Company for federal income tax purposes and its initial
fair market value.

         Members.

         the receipt of any notice from the Internal Revenue Service in any
         administrative proceeding at the Company level relating to the
         determination of any Company item of income, gain, loss, deduction or
         credit, mail or otherwise deliver a copy of such notice to each Member.

          Section 11.2 Taxation as Partnership. The Company shall be treated as

                                   ARTICLE XII

                   LIABILITY, EXCULPATION AND INDEMNIFICATION

         Section 12.1 Liability. Except as otherwise provided by the Delaware
Act, the debts, obligations and liabilities of the Company, whether arising in
contract, tort or otherwise, shall be solely the debts, obligations and
liabilities of the Company, and no Covered Person shall be obligated personally
for any such debt, obligation or liability of the Company solely by reason of
being a Covered Person.

         Section 12.2  Exculpation.

                 12.2.1 No Covered Person shall be liable to the Company or any
         other Covered Person for any loss, damage or claim incurred by reason
         of any act or omission performed or omitted by such Covered Person in
         good faith on behalf of the Company and in a


                                       13
<PAGE>
 
         manner reasonably believed to be within the scope of authority
         conferred on such Covered Person by this Agreement, except that a
         Covered Person shall be liable for any such loss, damage or claim
         incurred by reason of such Covered Person's gross negligence or willful
         misconduct.

                  12.2.2 A Covered Person shall be fully protected in relying in
         good faith upon the records of the Company and upon such information,
         opinions, reports or statements presented to the Company by any Person
         as to matters the Covered Person reasonably believes are within such
         other Person's professional or expert competence and who has been
         selected with reasonable care by or on behalf of the Company, including
         information, opinions, reports or statements as to the value and amount
         of the assets, liabilities, Profits,
         Losses or Net Cash Flow or any other facts pertinent to the existence
         and amount of assets from which distributions to Members might properly
         be paid.

         Section 12.3 Fiduciary Duty. To the extent that, at law or in equity, a
Covered Person has duties (including fiduciary duties) and liabilities relating
thereto to the Company or to any other Covered Person, a Covered Person acting
under this Agreement shall not be liable to the Company or to any Member for its
good faith reliance on the provisions of this Agreement. The provisions of this
Agreement, to the extent that they restrict the duties and liabilities of a
Covered Person otherwise existing at law or in equity, are agreed by the parties
hereto to replace such other duties and liabilities of such Covered Person.

         Section 12.4 Indemnification. To the fullest extent permitted by
applicable law, a Covered Person shall be entitled to indemnification from the
Company for any loss, damage or claim incurred by such Covered Person by reason
of any act or omission performed or omitted by such Covered Person in good faith
on behalf of the Company and in a manner reasonably believed to be within the
scope of authority conferred on such Covered Person by this Agreement, except
that no Covered Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Covered Person by reason of gross
negligence or willful misconduct with respect to such acts or omissions;
provided, however, that any indemnity under this Section 12.4 shall be provided
out of and to the extent of Company assets only, and no Covered Person shall
have any personal liability on account thereof.

         Section 12.5 Expenses. To the fullest extent permitted by applicable
law, expenses (including legal fees) incurred by a Covered Person in defending
any claim, demand, action, suit or proceeding shall, from time to time, be
advanced by the Company prior to the final disposition of such claim, demand,
action, suit or proceeding upon receipt by the Company of an undertaking by or
on behalf of the Covered Person to repay such amount if it shall be determined
that the Covered Person is not entitled to be indemnified as authorized in
Section 12.4 hereof.

         Section 12.6 Insurance. The Company may purchase and maintain
insurance, to the extent and in such amounts as the Members shall, in their sole
discretion, deem reasonable, on behalf of Covered Persons and such other Persons
as the Members shall determine, against any


                                       14
<PAGE>
 
liability that may be asserted against or expenses that may be incurred by any
such Person in connection with the activities of the Company or such
indemnities, regardless of whether the Company would have the power to indemnify
such Person against such liability under the provisions of this Agreement. The
Members and the Company may enter into indemnity contracts with Covered Persons
and such other Persons as the Members shall determine and adopt written
procedures pursuant to which arrangements are made for the advancement of
expenses and the funding of obligations under Section 12.5 hereof and containing
such other procedures regarding indemnification as are appropriate.

         Section 12.7 Outside Businesses. Any Member or Affiliate thereof may
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the business
of the Company, and the Company and the Members shall have no rights by virtue
of this Agreement in and to such independent ventures or the income or profits
derived therefrom, and the pursuit of any such venture, even if competitive with
the business of the Company, shall not be deemed wrongful or improper. No Member
or Affiliate thereof shall be obligated to present any particular investment
opportunity to the Company even if such opportunity is of a character that, if
presented to the Company, could be taken by the Company, and any Member or
Affiliate thereof shall have the right to take for its own account (individually
or as a partner or fiduciary) or to recommend to others any such particular
investment opportunity.


                                  ARTICLE XIII

                               ADDITIONAL MEMBERS

         Section 13.1 Admission. By approval of all of the Members, the Company
is authorized to admit any Person as an additional member of the Company (each,
an "Additional Member" and collectively, the "Additional Members"). Each such
Person shall be admitted as an Additional Member at the time such Person (i)
executes this Agreement or a counterpart of this Agreement and (ii) is named as
a Member on Schedule A hereto. The legal fees and expenses associated with such
admission shall be borne by the Company.

         Section 13.2 Allocations. Additional Members shall not be entitled to
any retroactive allocation of the Company's income, gains, losses, deductions,
credits or other items; provided that, subject to the restrictions of Section
706(d) of the Code, Additional Members shall be entitled to their respective
share of the Company's income, gains, losses, deductions, credits and other
items arising under contracts entered into before the effective date of the
admission of any Additional Members to the extent that such income, gains,
losses, deductions, credits and other items arise after such effective date. To
the extent consistent with Section 706(d) of the Code and Treasury Regulations
promulgated thereunder, the Company's books may be closed at the time Additional
Members are admitted (as though the Company's tax year had ended) or the Company
may credit to the Additional Members pro rata allocations of the Company's
income,

                                       15
<PAGE>
 
gains, losses, deductions, credits and items for that portion of the
Company's Fiscal Year after the effective date of the admission of the
Additional Members.


                                   ARTICLE XIV

         Section 14.1 Assignability of Interests. No Member may assign the whole
or any part of its Interests.

         Section 14.2 Recognition of Assignment by Company. No assignment or
pledge of any Interest, or any part thereof, that is in violation of this
Article XIV shall be valid or effective, and neither the Company nor the Members
shall recognize the same for the purpose of making distributions pursuant to
this Agreement. Neither the Company nor the Members shall incur any liability as
a result of refusing to make any such distributions to the assignee of any such
invalid assignment.

         Section 14.3 Pledge. No Member may pledge or otherwise encumber the
whole or any part of its Interests.


                                   ARTICLE XV

                    DISSOLUTION, LIQUIDATION AND TERMINATION

         Section 15.2 Events Causing Dissolution. The Company shall be dissolved
and its affairs shall be wound up upon the occurrence of any of the following

         in Section 2.3 hereof;

                  15.2.2   the written consent of all Members;

                  15.2.3 the death, retirement, resignation, expulsion,
         bankruptcy or dissolution of a Member or the occurrence of any other
         event under the Delaware Act that terminates the continued membership
         of a Member in the Company unless, within ninety (90) days after the
         occurrence of such an event, all of the remaining Members agree in
         writing to continue the business of the Company; or



         
                                       16
<PAGE>
 
                 15.2.4 the entry of a decree of judicial dissolution under
         Section 18-802 of the Delaware Act.

         Section 15.3 Liquidation. Upon dissolution of the Company, the Members
shall carry out the winding up of the Company and shall immediately commence to
wind up the Company's affairs; provided, however, that a reasonable time shall
be allowed for the orderly liquidation of the assets of the Company and the
satisfaction of liabilities to creditors so as to enable the Members to minimize
the normal losses attendant upon a liquidation. The Members shall continue to
share Profits and Losses during liquidation in the same proportions, as
specified in Article VIII hereof, as before liquidation. The proceeds of
liquidation shall be distributed in the following order and priority:


                 15.3.1 to creditors of the Company, including Members who are
         creditors, to the extent otherwise permitted by law, in satisfaction of
         the liabilities of the Company (whether by payment or the making of
         reasonable provision for payment thereof); and

                 15.3.2 to the Members in accordance with their Capital Account
         balances, after giving effect to all contributions, distributions and
         allocations for all periods.

         Section 15.4 Termination. The Company shall terminate when all of the
assets of the Company, after payment of or due provision for all debts,
liabilities and obligations of the Company, shall have been distributed to the
Members in the manner provided for in this Article XV and the Certificate shall
have been canceled in the manner required by the Delaware Act.

         Section 15.5 Claims of the Members. The Members and former Members
shall look solely to the Company's assets for the return of their Capital
Contributions, and if the assets of the Company remaining after payment of or
due provision for all debts, liabilities and obligations of the Company are
insufficient to return such Capital Contributions, the Members and former
Members shall have no recourse against the Company or any other Member.


                                   ARTICLE XVI

                                  MISCELLANEOUS

         Company.

All such notices shall be deemed to have been given when received.

         Section 16.2 Failure to Pursue Remedies. The failure of any party to
seek redress for violation of, or to insist upon the strict performance of, any
provision of this Agreement shall not prevent a subsequent act, which would have
originally constituted a violation, from having the effect of an original
violation.

         Section 16.3 Cumulative Remedies. The rights and remedies provided by
this Agreement are cumulative and the use of any one right or remedy by any
party shall not preclude or waive its right to use any or all other remedies.
Said rights and remedies are given in addition to any other rights the parties
may have by law, statute, ordinance or otherwise.

         Section 16.4 Binding Effect. This Agreement shall be binding upon and
inure to the benefit of all of the parties and, to the extent permitted by this
Agreement, their successors, legal representatives and assigns.

         Section 16.5 Interpretation. Throughout this Agreement, nouns, pronouns
and verbs shall be construed as masculine, feminine, neuter, singular or plural,

particular provision of this Agreement shall not affect the other provisions
hereof, and this Agreement shall be construed in all respects as if such invalid
or unenforceable provision was omitted.

         Section 16.7 Counterparts. This Agreement may be executed in any number
of counterparts with the same effect as if all parties hereto had signed the
same document. All counterparts shall be construed together and shall constitute
one instrument.

agreement among the parties hereto pertaining to the subject matter hereof and
supersedes all prior agreements and understandings pertaining thereto.

         Section 16.9 Governing Law. This Agreement and the rights of the
parties hereunder shall be interpreted in accordance with the laws of the State
of Delaware, and all rights and remedies shall be governed by such laws without
regard to principles of conflict of laws.

Ladies and Gentlemen:

     Centennial Cellular Operating Co. LLC, a Delaware limited liability company
(the "Issuer"), and Centennial Finance Corp., a Delaware corporation (which will
be merged with and into Centennial Cellular Corp., a Delaware corporation
("Centennial"), upon consummation of the Merger (as defined below)), as co-
obligor ("Finance Corp."), confirm their respective agreements with Merrill
Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill
Lynch") and each of the other Initial Purchasers named in Schedule A hereto
(collectively, the "Initial Purchasers"), for whom Merrill Lynch is acting as
representative (in such capacity, the "Representative"), with respect to the
issue and sale by the Issuer and Finance Corp., jointly and severally, and the
purchase by the Initial Purchasers, acting severally and not jointly, of
$370,000,000 (including the approximate amount necessary to fund an interest
escrow equal to the first three regularly scheduled semi-annual interest
payments on the Notes (the "Interest Escrow")) aggregate principal amount of the
Issuer's and Finance Corp.'s Senior 


                                      -1-
<PAGE>
 
Subordinated Notes due 2008 (the "Securities"). Each Initial Purchaser shall
purchase, severally and not jointly, an amount of Securities equal to the total
amount of Securities purchased by all Initial Purchasers multiplied by the
percentage set forth next to its name in Schedule A hereto. The Securities are
to be issued pursuant to an indenture dated as of December 14, 1998 (the
"Indenture") among the Issuer, Finance Corp. and The Chase Manhattan Bank, as
trustee (the "Trustee"). Securities issued in book-entry form will be issued to
Cede & Co. as nominee of The Depository Trust Company ("DTC") pursuant to a
letter agreement, to be dated as of the Closing Time (as defined in Section
2(b)) (the "DTC Agreement"), among the Issuer, Finance Corp., the Trustee and
DTC.

     The Securities are being issued as part of the financing necessary to
effect the merger (the "Merger") of CCW Acquisition Corp., a Delaware
corporation ("Acquisition"), with and into Centennial, whereby Centennial will
be the surviving corporation in the Merger.  The Merger will be effected
pursuant to the Merger Agreement, dated as of July 2, 1998, between Centennial
and Acquisition, as amended on November 29, 1998 (as amended, the "Merger
Agreement").  Immediately following consummation of the Merger, Centennial (a)
shall cause all shares of capital stock and other equity interests of its
existing operating subsidiaries to be directly or indirectly contributed to the
Issuer and (b) shall have no other material assets other than its interest in
the capital stock of the Issuer.  Upon consummation of the Merger, Finance Corp.
will merge with and into Centennial, which will become a joint and several co-
obligor of the Securities.

     In connection with the Merger, Acquisition has received commitments from
Merrill Lynch Capital Corporation and others to provide the Issuer with $1.050
billion in senior secured credit facilities (the "Credit Facilities").
Acquisition has received commitments for $400 million in equity contributions
(the "Equity Contribution") from several investors (the "Equity Investors") and
Centennial has received a commitment from WCAS Capital Partners III, L.P. to
purchase senior subordinated notes in an aggregate principal amount of $180
million (the "Subordinated Notes"), as well as common stock of Centennial, for a
total price of $180 million (the "Mezzanine Financing").  In connection with the
Equity Contribution, the Equity Investors and Acquisition will enter into a
securities purchase agreement, stockholders agreement and registration rights
agreement which will govern the terms of their investment (the "Investment
Agreements").  Centennial will make and consummate tender offers (the "Tender
Offers") to acquire all of its 8 7/8% Senior Notes due 2001 (the "1993 Notes")
and its 10 1/8% Senior Notes due 2005 (the "1995 Notes" and together with the
1993 Notes, the "Old Notes").  The Merger Agreement, the Credit Facilities, the
Investment Agreements, and the agreements in connection with the Equity
Contribution, the Mezzanine Financing and the Tender Offers and all other
documents and instruments executed in connection with or pursuant to any of the
foregoing are collectively referred to herein as the "Recapitalization
Documents."  The Merger, the borrowings pursuant to the Credit Facilities, the
Equity Contribution, the Mezzanine Financing, the Tender Offers and the issuance
of the Securities are collectively referred to herein as the "Recapitalization
Transactions."

     Pending consummation of the Merger, the Initial Escrow Funds (as defined in
the Offering Memorandum) (which consist of the net proceeds from the sale of the
Securities and 


                                      -2-
<PAGE>
 
cash in the amount of $25 million from the Equity Investors (the "Additional
Escrow Amount")) will be held by the Trustee in an escrow and pledge account
(the "Initial Escrow and Pledge Account") pursuant to a Pledge and Escrow
Agreement (the "Pledge and Escrow Agreement"). The Initial Escrow Funds will be
required to be invested in Cash Equivalents (as defined in the Offering
Memorandum). The Issuer will be permitted to obtain release of the Initial
Escrow Funds (other than an amount necessary to purchase the Pledged Securities
(as defined in the Pledge and Escrow Agreement)) upon consummation of the Merger
and related transactions provided that at that time (a) Centennial shall have
received the Equity Contribution and Mezzanine Financing of at least $580
million, (b) (i) the Issuer shall have incurred or assumed no more than $1.350
billion and no less than $1.250 billion of Indebtedness under the Credit
Facilities and the Securities and (ii) Centennial shall have outstanding under
the Credit Facility, the Securities and the Mezzanine Financing no more than
$1.550 billion (less the principal amount of Old Notes not tendered and not
defeased) and no less than $1.40 billion of Indebtedness (plus the amount of any
(x) Old Notes which have been properly defeased and (y) Equity Contribution and
Mezzanine Financing in excess of $580 million less the principal amount of Old
Notes not tendered and not defeased) and (c) (i) the Issuer and its Restricted
Subsidiaries shall not have outstanding more than $25 million of Indebtedness
for borrowed money (other than the Securities and the borrowings under the
Credit Facilities) and (ii) Centennial shall not have outstanding more than $25
million of Indebtedness for borrowed money (other than its obligations under the
Securities and the Credit Facilities, the Mezzanine Financing and any remaining
Old Notes which have been properly defeased or not tendered and not defeased)
(collectively, the "Financing Condition"). Upon the earlier to occur of (i)
termination of the Merger Agreement and (ii) 60 days after the Issue Date (as
defined in the Offering Memorandum) (which date may be extended to 90 days in
certain circumstances described in the Pledge and Escrow Agreement), if the
Initial Escrow Funds have not been released by that time, all of the outstanding
Securities will be subject to a Special Mandatory Redemption (as defined in the
Offering Memorandum) upon seven days' prior written notice to the Holders with
the Initial Escrow Funds at a redemption price equal to 101% of the principal
amount plus accrued and unpaid interest, if any, to the date of redemption.

     Upon the closing of the Merger, Finance Corp. will merge with and into
Centennial, with Centennial as the surviving corporation, and Centennial will
assume by Supplemental Indenture (the "Supplemental Indenture") all of Finance
Corp.'s obligations, and the co-obligors under the Securities and the Indenture
will at such time and thereafter be the Issuer and Centennial.  Upon the closing
of the Merger, pursuant to the Pledge and Escrow Agreement the Issuer and
Centennial must purchase and pledge the Pledged Securities in such amount as
will be sufficient upon receipt of scheduled interest and principal payments of
such securities to provide for payment of the first three scheduled interest
payments due on the Securities (unless already paid).

     The Issuer and Finance Corp. understand that the Initial Purchasers propose
to make an offering of the Securities on the terms and in the manner set forth
herein and agree that the Initial Purchasers may resell, subject to the
conditions set forth herein, all or a portion of the Securities to purchasers
("Subsequent Purchasers") at any time after the date of this Agreement.  The
Securities are to be offered and sold through the Initial Purchasers without
being registered under 

                                      -3-
<PAGE>
 
the Securities Act of 1933, as amended (the "1933 Act"), in reliance upon
exemptions therefrom. Pursuant to the terms of the Securities and the Indenture,
investors that acquire the Securities may only resell or otherwise transfer such
Securities if such Securities are hereafter registered under the 1933 Act or if
an exemption from the registration requirements of the 1933 Act is available
(including the exemption afforded by Rule 144A ("Rule 144A") or Regulation S
("Regulation S") of the rules and regulations promulgated under the 1933 Act by
the Securities and Exchange Commission (the "Commission")).

     Centennial, the Issuer and Finance Corp. have prepared and delivered to
each Initial Purchaser copies of a preliminary offering memorandum dated
November 30, 1998 (the "Preliminary Offering Memorandum") and have prepared and
will deliver to each Initial Purchaser, on the date hereof or the next
succeeding day, copies of a final offering memorandum dated December 9, 1998
(the "Final Offering Memorandum"), each to be used by such Initial Purchaser in
connection with its solicitation of purchases of, or offering of, the
Securities.  "Offering Memorandum" means, for purposes of this Agreement, each
of the Preliminary Offering Memorandum and the Final Offering Memorandum.

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the Offering
Memorandum (or other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
is incorporated by reference in the Offering Memorandum;  and all references in
this Agreement to amendments or supplements to the Offering Memorandum shall be
deemed to mean and include the filing of any document under the Securities
Exchange Act of 1934 (the "1934 Act") which is incorporated by reference in the
Offering Memorandum.

     The holders of the Securities will be entitled to the benefits of the
registration rights agreement to be dated as of the Closing Time (the
"Registration Rights Agreement"), among the Issuer, Finance Corp. and the
Initial Purchasers.

     SECTION 1.  Representations and Warranties.

     (a) Representations and Warranties by the Issuer and Finance Corp.

     The Issuer and Finance Corp., jointly and severally, represent and warrant
to each Initial Purchaser as of the date hereof and as of the Closing Time
referred to in Section 2(b) hereof, and agree with each Initial Purchaser as
follows:

          (i)   Similar Offerings.  None of Centennial, the Issuer, Finance
                -----------------
     Corp. or any of their respective Subsidiaries has, directly or indirectly,
     solicited any offer to buy or offered to sell, or will, directly or
     indirectly, solicit any offer to buy or offer to sell, in the United States
     or to any United States citizen or resident, any security which is or would
     be integrated with the sale of the Securities in a manner that would
     require the Securities to be registered under the 1933 Act.

          (ii)  Offering Memorandum.  The Offering Memorandum does not, and at
                -------------------
     the Closing Time will not, include an untrue statement of a material fact
     or omit to state a 


                                      -4-
<PAGE>
 
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;
     provided, that this representation, warranty and agreement shall not apply
     to statements in or omissions from the Offering Memorandum made in reliance
     upon and in conformity with information furnished to the Issuer or Finance
     Corp. in writing by any Initial Purchaser expressly for use in the Offering
     Memorandum.

          (iii)  Independent Accountants.  The accountants who certified the
                 -----------------------
     financial statements and supporting schedules included in the Offering
     Memorandum are independent certified public accountants with respect to
     Centennial and its Subsidiaries (as defined below) within the meaning of
     Regulation S-X under the 1933 Act.

          (iv)   Financial Statements.  The financial statements, together with
                 --------------------
     the related schedules and notes, included in the Offering Memorandum
     present fairly the financial position of Centennial and its consolidated
     subsidiaries at the dates indicated and the statements of income, changes
     in shareholders' equity and cash flows of Centennial and its consolidated
     subsidiaries for the periods specified; said financial statements have been
     prepared in conformity with United States generally accepted accounting
     principles ("GAAP") applied on a consistent basis throughout the periods
     involved. The selected financial data and the summary financial information
     included in the Offering Memorandum present fairly the information shown
     therein and have been compiled on a basis consistent with that of the
     audited financial statements included in the Offering Memorandum. The pro
     forma financial statements of Centennial and its Subsidiaries and the
     related notes thereto, and the other pro forma financial information
     included in the Offering Memorandum, present fairly the information shown
     therein, have been prepared in all material respects in accordance with the
     Commission's rules and guidelines with respect to pro forma financial
     statements included in a registration statement under the 1933 Act and have
     been properly compiled on the bases described therein, and the assumptions
     used in the preparation thereof are reasonable and the adjustments used
     therein are appropriate to give effect to the transactions and
     circumstances referred to therein. The financial statements included in the
     Offering Memorandum are the only financial statements which would be
     required by Regulation S-X to be included in the Offering Memorandum if the
     Offering Memorandum was a registration statement on Form S-1. The Merger
     may be accounted for as a "recapitalization" for financial reporting
     purposes.

          (v)    No Material Adverse Change in Business. Since May 31, 1998, (A)
                 --------------------------------------
     there has been no material adverse change in the financial condition,
     earnings, or business affairs of Centennial, the Issuer and their
     Subsidiaries considered as one enterprise, whether or not arising in the
     ordinary course of business (a "Material Adverse Effect"), (B) there have
     been no transactions entered into by Centennial, the Issuer or any of their
     Subsidiaries, other than those contemplated hereby or in the ordinary
     course of business, which are material with respect to Centennial, the
     Issuer and their Subsidiaries considered as one enterprise, and (C) there
     has been no dividend or distribution of any

                                       -5-
<PAGE>
 
     kind declared, paid or made by Centennial, the Issuer or any of their
     Subsidiaries on any class of their capital stock or other equity interest.

          (vi)   Good Standing of the Issuer.  The Issuer has been duly formed
                 ---------------------------
     and is validly existing as a limited liability company in good standing
     under the laws of the State of Delaware and has power and authority to own,

     as a foreign limited liability company to transact business and is in good
     standing in each other jurisdiction in which such qualification is required
     or will be required after the Merger, whether by reason of the ownership or
     leasing of property or the conduct of business, except where the failure so
     to qualify or to be in good standing would not result in a Material Adverse
     Effect.

          (vii)  Good Standing of Centennial.  Centennial has been duly
                 ---------------------------
     organized and is validly existing as a corporation in good standing under

     reserves have been provided. Centennial and its Subsidiaries have filed all
     other tax returns that are required to have been filed by them pursuant to
     applicable foreign, federal, state, local or other law except insofar as

     taxes, if any, as are being contested in good faith and by appropriate
     proceedings and as to which adequate reserves have been provided. The
     charges, accruals and reserves on the books of Centennial and its
     Subsidiaries in respect of all federal, state, local and foreign tax
     liabilities of Centennial and each Subsidiary of Centennial for any years
     not finally determined are adequate to meet any assessments or re-

     without limitation, contingent liabilities, of such person, (b) the present

     to, and does not believe that it will, incur debts and liabilities beyond
     such person's ability to pay as such debts and liabilities mature, (d) such

     facilitate the sale or resale of the Securities. Centennial, the Issuer and
     their Subsidiaries have not distributed and, prior to the later to occur of

<PAGE>
 
other jurisdiction, and (y) prior to the completion of the placement of the
Securities by the Initial Purchasers, any material changes in or affecting the
earnings, business affairs or business prospects of Centennial, the Issuer and
their Subsidiaries which (i) make any statement in any Offering Memorandum or
any document incorporated by reference in any Offering Memorandum false or
misleading or (ii) are not disclosed in the Offering Memorandum. In such event
or if during such time any event shall occur or condition shall exist as a
result of which it is necessary, in the opinion of the Issuer, Finance Corp.,
their counsel, the Initial Purchasers or counsel for the Initial Purchasers, to
amend or supplement any Offering Memorandum in order that such Offering
Memorandum not include any untrue statement of a material fact or omit to state
a material fact necessary in order to make the statements therein not misleading
in the light of the circumstances then existing, the Issuer and Finance Corp.
will forthwith amend or supplement such Offering Memorandum by preparing and
furnishing to each Initial Purchaser an amendment or amendments of, or a
supplement or supplements to, such Offering Memorandum (in form and substance
satisfactory in the reasonable opinion of counsel for the Initial Purchasers) so
that, as so amended or supplemented, the Offering Memorandum will not include an
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements therein, in the light of the circumstances
existing at the time it is delivered to a Subsequent Purchaser, not misleading.

     (c) Amendment to Offering Memorandum and Supplements.  The Issuer and
Finance Corp. will advise each Initial Purchaser promptly of any proposal to
amend or supplement any Offering Memorandum and will not effect such amendment
or supplement without the consent of the Initial Purchasers. Neither the consent
of the Initial Purchasers to, nor the Initial Purchaser's delivery of, any such
amendment or supplement, shall constitute a waiver of any of the conditions set
forth in Section 5 hereo f.

     (d) Qualification of Securities for Offer and Sale. The Issuer and Finance
Corp. will use their best efforts to register or qualify the Securities for
offering and sale under the applicable securities laws of such jurisdictions as

Issuer and Finance Corp. shall not be obligated to file any general consent to
service of process or to qualify as a foreign corporation or as a dealer in
securities in any jurisdiction in which it is not so qualified or to subject
itself to taxation in respect of doing business in any jurisdiction in which it
is not otherwise so subject.

     (e) Integration.  The Issuer and Finance Corp. agree that they will not
and will cause their affiliates not to make any offer or sale of securities of
Centennial, the Issuer or Finance Corp., as the case may be, of any class if, as
a result of the doctrine of "integration" referred to in Rule 502 under the 1933
Act, such offer or sale could be deemed to render invalid (for the purpose of
(i) the sale of the Securities by the Issuer and Finance Corp. to the Initial
Purchasers, (ii) the resale of the Securities by the Initial Purchasers to
Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent
Purchasers to others) the exemption from the registration requirements of the
1933 Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S

Corp. will pledge for the benefit of the holders of the Notes government

counsel for the Initial Purchasers.

Agreement may be terminated by the Representative by notice to the Issuer and
Finance Corp. at any time at or prior to the Closing Time, and such termination

and remain in full force and effect.

     SECTION 6.  Indemnification.
                 --------------- 
     (a) Indemnification of Initial Purchasers.  The Issuer and Finance Corp.,
jointly and severally, agree to indemnify and hold harmless each Initial
Purchaser and each person, if any, who controls any Initial Purchaser within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in any Preliminary Offering
     Memorandum or the Final Offering Memorandum (or any amendment or supplement
     thereto (including any document incorporated by reference into the
     Preliminary Offering Memorandum or Final Offering Memorandum)), or the
     omission or alleged omission therefrom of a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or 

                                     -25-
<PAGE>
 
     omission, or any such alleged untrue statement or omission; provided that
     (subject to Section 6(d) below) any such settlement is effected with the
     written consent of Centennial and the Issuer; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by Merrill Lynch), reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any governmental agency or body,
     commenced or threatened, or any claim whatsoever based upon any such untrue
     statement or omission, or any such alleged untrue statement or omission, to
     the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
- --------  -------                                                            
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to Centennial, the
Issuer and Finance Corp. by any Initial Purchaser through Merrill Lynch
expressly for use in the Offering Memorandum (or any amendment thereto);
provided, further, that the Issuer and Finance Corp. will not be liable to the
- --------  -------                                                             
Initial Purchasers or any person controlling such Initial Purchasers with
respect to any such untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Offering Memorandum to the extent that
the Issuer and Finance Corp. shall sustain the burden of proving that any such
loss, liability, claim, damage or expense resulted from the fact that the
Initial Purchaser sold securities to a person to whom such Initial Purchaser
failed to send or give, at or prior to the written confirmation of the sale of
such Securities, a copy of the Final Offering Memorandum (as amended or
supplemented) if the Issuer and Finance Corp. have previously furnished copies
thereof to the Initial Purchasers (sufficiently in advance of the Closing Time
to allow for distribution of the Final Offering Memorandum in a timely manner)
and complied with their obligations under Sections 3(b) and 3(c) hereof and the
loss, liability, claim, damage or expense of the Initial Purchasers resulted
from an untrue statement or omission or alleged untrue statement or omission of
a material fact contained in or omitted from such Preliminary Offering
Memorandum (as amended or supplemented) which was corrected in the Final
Offering Memorandum (as amended or supplemented).

     (b) Indemnification of the Issuer, Finance Corp. and Directors.  Each
Initial Purchaser severally agrees to indemnify and hold harmless the Issuer,
Finance Corp. and their directors, and each person, if any, who controls the
Issuer or Finance Corp. within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act against any and all loss, liability, claim, damage
and expense described in the indemnity contained in subsection (a) of this
Section, as incurred, but only with respect to untrue statements or omissions,
or alleged untrue statements or omissions, made in the Offering Memorandum in
reliance upon and in conformity with written information furnished to the Issuer
or Finance Corp. by such Initial Purchaser expressly for use in the Offering
Memorandum.

     (c) Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an 

                                     -26-
<PAGE>
 
indemnifying party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have otherwise
than on account of this indemnity agreement. In the case of parties indemnified
pursuant to Section 6(a) above, counsel to the indemnified parties shall be
selected by Merrill Lynch, and, in the case of parties indemnified pursuant to
Section 6(b) above, counsel to the indemnified parties shall be selected by the
Issuer and Finance Corp. An indemnifying party may participate at its own
expense in the defense of any such action; provided, however, that counsel to
                                           --------  -------
the indemnifying party shall not (except with the consent of the indemnified
party) also be counsel to the indemnified party. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 6 or Section 7 hereof (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.


     (d) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 60 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

     SECTION 7.  Contribution.  If the indemnification provided for in Section 6
                 ------------
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Issuer and Finance
Corp. on the one hand and the Initial Purchasers on the other hand from the
offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the Issuer and Finance Corp. on the one
hand and of the Initial Purchasers on the other hand in connection with the
statements or omissions which resulted in 

                                     -27-
<PAGE>
 
such losses, liabilities, claims, damages or expenses, as well as any other
relevant equitable considerations.

     The relative benefits received by the Issuer and Finance Corp. on the one
hand and the Initial Purchasers on the other hand in connection with the
offering of the Securities pursuant to this Agreement shall be deemed to be in
the same respective proportions as the total net proceeds from the offering of
the Securities pursuant to this Agreement (before deducting expenses) received
by the Issuer and Finance Corp. and the total underwriting discount received by
the Initial Purchasers, bear to the aggregate initial offering price of the
Securities.

     The relative fault of the Issuer and Finance Corp. on the one hand and the
Initial Purchasers on the other hand shall be determined by reference to, among
other things, whether any such untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by the Issuer and Finance Corp. or by the Initial
Purchasers, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     The Issuer, Finance Corp. and the Initial Purchasers agree that it would
not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
Section 7.  The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
7 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
Initial Purchaser has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each person, if any, who controls an
Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall have the same rights to contribution as such Initial
Purchaser, and each director of the Issuer, Finance Corp. and each person, if
any, who controls the Issuer and Finance Corp. within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Issuer and Finance Corp.  The Initial Purchasers' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the principal amount of Securities set forth opposite their respective names
in Schedule A hereto and not joint.

                                     -28-

     SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.
                 ------------------------------------------------------------- 
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of Centennial, the Issuer or any of their Subsidiaries
submitted pursuant hereto, shall remain operative and in full force and effect,
regardless of any investigation made by or on behalf of any Initial Purchaser or
controlling person, or by or on behalf of Centennial, the Issuer or any
Subsidiary, and shall survive delivery of the Securities to the Initial
Purchasers.

     SECTION 9.  Termination of Agreement.
                 ------------------------ 

     (a)  Termination; General.  The Representative may terminate this
Agreement, by notice to the Issuer and Finance Corp., at any time at or prior to
the Closing Time (i) if there has been, since the time of execution of this
Agreement or since May 31, 1998, a Material Adverse Effect, or (ii) if trading
in any securities of Centennial or the Issuer has been suspended or limited by
the Commission or the NASDAQ National Market System, or if trading generally on
the American Stock Exchange or the New York Stock Exchange or in the NASDAQ
National Market System has been suspended or limited, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices have been
required, by any of said exchanges or by such system or by order of the
Commission, the National Association of Securities Dealers, Inc. or any other
governmental authority, or (iii) if a banking moratorium has been declared by
either Federal or New York authorities.

     (b)  Liabilities.  If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6 and 7 shall survive such termination and remain in full force and effect.

     SECTION 10. [Intentionally Omitted.]
                 ------------------------

     SECTION 11.  Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed, delivered

     SECTION 12. Parties.  This Agreement shall each inure to the benefit of
                 -------
and be binding upon the Initial Purchasers, the Issuer, Finance Corp. and their
respective successors (including Centennial as the successor to Finance Corp.
but solely upon consummation of the Merger). Nothing expressed or mentioned in
this Agreement is intended or shall be construed to give any person, firm or
corporation, other than the Initial Purchasers, the Issuer, Finance Corp. and
their respective successors and the controlling persons and directors referred
to in Sections 6 and 7 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in

deemed to be a successor by reason merely of such purchase.

                  -----------------------
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED

  The undersigned acknowledges receipt of the Prospectus dated    , 1999 (the
"Prospectus"), of Centennial Cellular Corp., a Delaware corporation
("Centennial"), and Centennial Cellular Operating Co. LLC, a Delaware limited
liability company (together with Centennial, the "Issuers"), and this Letter
of Transmittal (the "Letter of Transmittal"), which together with the
Prospectus constitutes the Issuers' offer (the "Exchange Offer") to exchange
$1,000 principal amount of their 10 3/4% Senior Subordinated Notes due 2008,
Series B (the "New Notes"), for each $1,000 principal amount of their
outstanding 10 3/4% Senior Subordinated Notes due 2008, Series A (the "Old
Notes"). Recipients of the Prospectus should read the requirements described
in such Prospectus with respect to eligibility to participate in the Exchange
Offer. Capitalized terms used but not defined herein have the meaning given to
them in the Prospectus.
 
  The undersigned hereby tenders the Old Notes described under "Description of
Old Notes" below pursuant to the terms and conditions described in the
Prospectus and this Letter of Transmittal. The undersigned is the registered
owner of all the Old Notes, and the undersigned represents that it has
received from each beneficial owner of Old Notes ("Beneficial Owners") a duly
completed and executed form of "Instruction to Registered Holder from
Beneficiary Owner" accompanying this Letter of Transmittal, instructing the
undersigned to take the action described in this Letter of Transmittal.
 
  This Letter of Transmittal is to be used by a holder of Old Notes (i) if
certificates representing Old Notes are to be forwarded herewith, (ii) if
delivery of Old Notes is to be made by book-entry transfer to the Exchange
Agent's account at The Depository Trust Company ("DTC"), pursuant to the
procedures set forth in the section of the Prospectus entitled "The Exchange
Offer," or (iii) if a tender is made pursuant to the guaranteed delivery
procedures in the section of the Prospectus entitled "The Exchange Offer."
 
  The undersigned hereby represents and warrants that the information received
from the beneficial owners is accurately reflected in the boxes entitled
"Beneficial Owner(s)--Purchaser Status" and "Beneficial Owner(s) Residence."
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact such registered holder of Old Notes promptly and
instruct such registered holder of Old Notes to tender on behalf of the
beneficial owner. If such beneficial owner wishes to tender on its own behalf,
such beneficial owner must, prior to completing and executing this Letter of
Transmittal and delivering its Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or
obtain a properly completed bond power from the registered holder of Old
Notes. The transfer of record ownership may take considerable time.
 
  In order to properly complete this Letter of Transmittal, a holder of Old
Notes must (i) complete the box entitled "Description of Old Notes," (ii)
complete the boxes entitled "Beneficial owner(s)--Purchaser Status" and
"Beneficial Owner(s)--Residence," (iii) if appropriate, check and complete the
boxes relating to book-entry transfer, guaranteed delivery, Special Issuance
Instructions and Special Delivery Instructions, (iv) sign the Letter of
Transmittal by completing the box entitled "Sign Here" and (v) complete the
Substitute Form W-9. Each holder of Old Notes should carefully read the
detailed instructions below prior to completing the Letter of Transmittal.
 
  Holders of Old Notes who desire to tender their Old Notes for exchange and
(i) whose Old Notes are not immediately available or (ii) who cannot deliver
their Old Notes, this Letter of Transmittal and all other documents required
hereby to the Exchange Agent on or prior to the Expiration Date, must tender
the Old Notes pursuant to the guaranteed delivery procedures set forth in the
section of the Prospectus entitled "The Exchange Offer." See Instruction 2.
 
  Holders of Old Notes who wish to tender their Old Notes for exchange must
complete columns (1) through (3) in the box below entitled "Description of Old
Notes," complete the boxes entitled and sign the box below entitled "Sign
Here." If only those columns are completed, such holder of Old Notes will have
tendered for exchange all Old Notes listed in column (3) below. If the holder
of Old Notes wishes to tender for exchange less than all of such Old Notes,
column (4) must be completed in full. In such case, such holder of Old Notes
should refer to Instruction 5.

                           IMPORTANT TAX INFORMATION
 
  Under current federal income tax law, a holder of Old Notes whose tendered
Old Notes are accepted for exchange may be subject to backup withholding
unless the holder provides the Issuers (as payor), through the Exchange Agent,
with either (i) such holder's correct taxpayer identification number ("TIN")
on Substitute Form W-9 attached hereto, certifying that the TIN provided on
Substitute Form W-9 is correct (or that such holder of Old Notes is awaiting a
TIN) and that (A) the holder of Old Notes has not been notified by the
Internal Revenue Service that he or she is subject to backup withholding as a
result of a failure to report all interest or dividends or (B) the Internal
Revenue Service has notified the holder of Old Notes that he or she is no
longer subject to backup withholding; or (ii) an adequate basis for exemption
from backup withholding. If such holder of Old Notes is an individual, the TIN
is such holder's social security number. If the Exchange Agent is not provided
with the correct taxpayer identification number, the holder of Old Notes may
be subject to certain penalties imposed by the Internal Revenue Service.
 
  Certain holders of Old Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt holders of Old Notes should indicate their
exempt status on Substitute Form W-9. A foreign individual may qualify as an
exempt recipient by submitting to the Exchange Agent a properly completed
Internal Revenue Service Form W-8 (which the Exchange Agent will provide upon
request) signed under penalty of perjury, attesting to the holder's exempt
status. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 (the "Guidelines") for additional
instructions.
 
  If backup withholding applies, the Issuers are required to withhold 31% of
any payment made to the holder of Old Notes or other payee. Backup withholding
is not an additional federal income tax. Rather, the federal income tax
liability of persons subject to backup withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be obtained from the Internal Revenue Service.
 
  The holder of Old Notes is required to give the Exchange Agent the TIN
(e.g., social security number or employer identification number) of the record
owner of the Old Notes. If the Old Notes are held in more than one name or are
not held in the name of the actual owner, consult the enclosed Guidelines for
additional guidance regarding which number to report.

Stock of the Company appearing opposite the name of such Stockholder on Schedule
I, Schedule II, Schedule III or Schedule IV hereto, as the case may be; and

                  WHEREAS, the Company and each of the Stockholders desire to

respect of all shares of capital stock of the Company (whether now or hereafter
acquired) owned by such Stockholder, and take all other appropriate action, and
the Company shall take all necessary and desirable actions within its control,

         Directors of the Company (the "Board") to be established at nine;

                  (ii)     the election to the Board of:

                           a) three directors designated by the holders of a
                  majority of the Common Stock then held by all WCAS
                  Purchasers (the "WCAS Designees") so long as the WCAS
                  Purchasers own (in the aggregate) not less than 25%
                  of the shares of Common Stock owned by them on the

                           b) two directors designated by the holders of a
                  majority of the Common Stock then held by all Blackstone
                  Purchasers (the "Blackstone Designees") so long as the
                  Blackstone Purchasers own (in the aggregate) not less than 25%
                  of the shares of Common Stock owned by them on the date
                  hereof, which directors will initially be Mark T. Gallogly and

                           c) the Chief Executive Officer and the Chief
                  Operation Officer of the Company (initially Michael J. Small
                  and Rudy J. Graf, respectively);

         all of which persons shall hold office, subject to their earlier
         removal in accordance with clause (iii) below, the By-laws of the
         Company and applicable corporate law, until their respective successors
         shall have been elected and shall have qualified;

                  (iii) the removal from the Board (with or without cause) of
         any director elected in accordance with subpart a) or b) of clause (ii)
         above upon the written request of the Stockholders that designated such
         director;

                  (iv) upon any vacancy in the Board as a result of any

         meeting such qualifications); and

                  (v) their respective designees to the Board of Directors of

                  (b) The two directors not designated pursuant to clause (ii)
of paragraph (a) above shall be directors (the "Outside Directors") that shall
be elected by the stockholders of the Company. In any such election, the
Stockholders shall vote their shares only for persons that (x) are not employees
or officers of (i) the Company or any of its subsidiaries or (ii) the
Stockholders or their respective stockholders, members or partners and (y)
otherwise qualify as "independent directors" under the rules applicable to
Nasdaq National Market companies as in effect on the date hereof and satisfy any
other requirements under applicable law or the rules of any exchange or
quotation system on which the Common Stock is then listed or traded.

                  (c) Each Stockholder agrees to use its best efforts to cause
its designees to the Board to vote or otherwise give such Director's consent to
the creation and maintenance of:

                  (i) a Compensation Committee of the Board consisting of three
         directors, two of whom shall be WCAS Designees, if any then exist, and
         the third of whom shall be a Blackstone Designee, if any then exist,
         which Compensation Committee shall approve all grants of stock options
         to employees of the Company, all increases in compensation of officers
         of the Company, all annual bonuses granted to officers of the Company
         and all other employee benefits (including, without limitation,
         vacation policy, benefit plans, company automobiles and insurance)
         granted to officers of the Company, and shall have such other duties
         and responsibilities as the Board of Directors may from time to time
         determine;

                  (ii) an Audit Committee of the Board of Directors, consisting
         of three directors, one of whom shall be a WCAS Designee, if any then
         exist, one of whom shall be a Blackstone Designee, if any then exist,
         and one of whom shall be an Outside Director, which Audit Committee
         shall review and approve the financial statements of the Company as
         audited by the Company's independent certified public accountants, and
         shall have such other duties and responsibilities as the Board of
         Directors may from time to time deter mine; and

                  (iii) such other committees as the Board shall from time to
         time deem appropri ate, consisting of at least two directors, at least
         one of whom shall be a WCAS Designee, if any then exist, and at least
         one of whom shall be a Blackstone Designee, if any then exist, which
         committees shall have such duties and responsibilities as the Board may
         from time to time determine.

                  To the extent there are no WCAS Designees or Blackstone
         Designees, the committee seats allocated to them above shall be filled
         as the Board shall determine.

                  (d) No Stockholder shall grant any proxy or enter into or
agree to be bound by any voting trust with respect to Common Stock held by it,
nor shall any Stockholder enter into any stockholder agreement or arrangement of
any kind with respect to Common Stock held by it, which conflicts or is
inconsistent in any manner with the provisions of this Agreement.

                  SECTION 2. Restrictions on Transfers by Management Purchasers.
In addition to the other restrictions set forth herein, each Management
Purchaser hereby agrees that such Management Purchaser shall not sell or in any
other way, directly or indirectly, transfer, assign, distribute or otherwise
dispose of any shares of capital stock (whether now owned or hereafter acquired)
then held by such Management Purchaser except:

                  (i) any transfer made with the prior written consent of the
         holders of a majority in interest of the shares of Common Stock then
         held by the WCAS Purchasers;

                  (ii) any transfer by such Management Purchaser to the spouse
         or lineal descendants of such Management Purchaser, including without
         limitation any transfer by bequest or devise, or to a trust or trusts
         for the benefit of such Management Purchaser or any of the foregoing;

                  (iii) any transfer of shares of capital stock that are the
         subject of an effective registration statement under the Securities Act
         of 1933, as amended (the "Securities Act"); or

                  (iv) any transfer of shares of capital stock pursuant to
         Section 3 or 4 hereof;

provided, in the case of a transfer pursuant to clause (i) or (ii) above, that
any such transferee that is not already a party to this Agreement shall agree in
writing to be bound by, and to comply with, all provisions of this Agreement as
though such transferee were a Management Purchaser.

                  SECTION 3.  Tag-Along Rights.

                  (a) Subject to the provisions of paragraph (d) below, if a
WCAS Purchaser or group of WCAS Purchasers (for purposes of this Section 3, a
"Selling Stockholder") wishes to directly or indirectly sell, transfer or
otherwise dispose of all or any portion of the Common Stock held by him, her or
it at any time, then such Selling Stockholder shall promptly deliver a notice
(an "Offering Notice") to the Company in writing of the proposed transfer,
specifying the number of such shares of Common Stock to be transferred by such
Selling Stockholder (such specified shares, the "Offered Shares"), the name of
the proposed purchaser or purchasers, the proposed purchase price per share, the
proposed date of transfer, the payment terms and all other material terms and
conditions thereof. In the event that the terms and/or conditions set forth in
the Offering Notice are thereafter amended in any respect, the Selling
Stockholder shall also give written notice (an "Amended Notice") of the amended
terms and conditions of the proposed transaction to the Company. Upon its
receipt of any Offering Notice or Amended Notice, the Company shall promptly,
but in all events within three (3) business days of its receipt thereof, forward
copies thereof to each of the Blackstone Purchasers, Signal Purchasers and
Management Purchasers (collectively, the "Other Stockholders"). The Selling
Stockholder shall provide such additional information with respect to the
proposed transfer as may be reasonably requested by the Company or the Other
Stockholders.

         
                                       4
<PAGE>
 
                  (b) Each Other Stockholder shall have the right and option,
exercisable upon written notice to the Company and the Selling Stockholder
within 15 days after receipt by such Other Stockholder of the Offering Notice,
or, if later, within 7 days after receipt by such Other Stockholder of the most
recent Amended Notice, to participate in the proposed transfer of shares by the
Selling Stockholder to the proposed purchaser on the same terms and conditions
as the Selling Stockholder (such participation right being hereinafter referred
to as a "tag-along" right); provided that no Other Stockholder shall be required
to make any representations or warranties or covenants, or bear any liability,
with respect to any other Stockholder or with respect to the Company or the
Company's business other than such Other Stockholder's pro rata share (based on
the number of shares of Common Stock to be transferred) of any indemnity
obligations for representations and warranties regarding the Company or its
business. Each Other Stockholder may participate in such transfer with respect
to all or any part of that number of shares of Common Stock which is equal to
the product obtained by multiplying (i) the number of Offered Shares by (ii) a
fraction, the numerator of which is the number of shares of Common Stock at the
time owned by such Other Stockholder and the denominator of which is the
aggregate number of shares of Common Stock then owned by the Stockholders. Any
Other Stockholders that have not notified the Selling Stockholder and the
Company of their intent to exercise their tag-along rights within 7 days after
receipt of an Amended Notice shall be deemed to have elected not to exercise
such rights with respect to the transaction contemplated by such Amended Notice
(regardless of their election pursuant to the Offering Notice or any prior
Amended Notice relating to such transaction), but only if such Amended Notice
sets forth the provisions of this sentence.

                  (c) Any Other Stockholder participating in the proposed
disposition shall deliver to the Company, as agent for such Other Stockholder,
for transfer to the proposed acquiror one or more certificates, properly
endorsed for transfer and with all stock transfer taxes paid and stamps affixed,
which represent the number of shares of Common Stock that such Other Stockholder
elects to dispose of pursuant to paragraph (b) above. The consummation of such
proposed disposition shall be subject to the sole discretion of the Selling
Stockholder, who shall have no liability or obligation whatsoever to any Other
Stockholder participating therein other than to obtain for such Other
Stockholder the same terms and conditions as those set forth in the Offering
Notice (or most recent Amended Notice, as the case may be). Upon the
consummation of any such sale, the Company (i) shall transfer to the acquiror a
stock certificate or certificates representing the number of shares of Common
Stock to be disposed of by any Other Stockholders and (ii) shall promptly
thereafter remit to each Other Stockholder (i) that portion of the proceeds of
the disposition to which such Other Stockholder is entitled by reason of such
participation and (ii) a stock certificate representing any balance of shares of
Common Stock that were not so disposed of (or all shares of Common Stock, in the
event the proposed disposition is not consummated).

                  (d) Anything to the contrary herein notwithstanding, the
provisions of this Section 3 shall not apply to (i) any transfer by a WCAS
Purchaser to any other WCAS Purchasers or affiliates thereof, (ii) any
distribution or transfer by any WCAS Purchaser that is a limited partnership to
its limited partners or (iii) in the case of a WCAS Purchaser who is an
individual,


                                       5
<PAGE>
 
transfer by such WCAS Purchaser to the spouse or lineal descendants of such WCAS
Purchaser, including, without limitation, transfer by bequest or devise, or to a
trust or trusts for the benefit of such WCAS Purchaser or any of the foregoing;
provided that in the case of a transfer pursuant to clause (i) or (iii) above,
such transferee agrees in writing to be bound by this Agreement as though such
transferee were a WCAS Purchaser.

                  (e) Each WCAS Purchaser, severally and not jointly, represents
and warrants to the Signal Purchasers that as of the date hereof there is no
contract, commitment or understanding between such person and any Blackstone
Purchaser with respect to "tag-along" or similar rights relating to shares of
capital stock of the Company, other than this Agreement. Each Blackstone
Purchaser, severally and not jointly, represents and warrants to the Signal
Purchasers that as of the date hereof there is no contract, commitment or
understanding between such person and any WCAS Purchaser with respect to
"tag-along" or similar rights relating to shares of capital stock of the
Company, other than this Agreement.

                  SECTION 4. Drag-Along Rights. In the event that any of the
WCAS Purchasers or the Company receives a bona fide offer from a third party not
affiliated with any WCAS Purchaser to purchase at least 80% of the outstanding
shares of capital stock of the Company and a majority in interest of the WCAS
Purchasers desires to accept such offer, and so long as the WCAS Purchasers
collectively own a greater number of outstanding shares of Common Stock than the
Blackstone Purchasers, such WCAS Purchasers shall have the right to require all
(but not less than all) of the Stockholders to sell all (or such lesser
percentage as may be necessary to achieve recapitalization accounting treatment,
but in no event less than 80%) of the shares of capital stock (together with any
options or warrants to acquire capital stock) then held by them (including all
or the same percent of all shares, options and warrants held by such WCAS
Purchasers) on the following terms:

                  (i) such sale shall only be a sale for cash or marketable
         securities and all expenses of the transaction, including, without
         limitation, legal, accounting and investment banking fees and expenses,
         shall be borne by the Company (for purposes of this paragraph,
         "marketable securities" shall mean securities which are debt or equity
         securities that are actively traded on a national securities exchange
         located in the United States or on Nasdaq that are part of an issue
         with a public capitalization in excess of $100 million and that may be
         freely traded without limitation as to volume on such exchange or
         Nasdaq immediately following receipt thereof or at any time thereafter
         by each Stockholder);

                  (ii) the proceeds from such sale (and, in the case of a sale
         of less than all of the outstanding shares of Common Stock of the
         Company, the number of shares to be sold by each Stockholder) shall be
         allocated among the Stockholders on a pro rata basis, based on the
         number of shares of Common Stock (treating all "in the money" options
         and warrants as the number of shares of Common Stock issuable upon the
         exercise thereof, less such number of shares of Common Stock the
         aggregate fair market value of which (based on
                             

                                       6
<PAGE>
 
         the value attributed in such sale) would be required to pay the 
         aggregate exercise price therefor, and treating any shares of
         convertible preferred stock or debt of the Company on an "as-converted"
         basis) then held by each Stockholder;

                  (iii) not less than 20 days prior to the closing date of such
         sale, such WCAS Purchasers shall notify each of the other Stockholders
         in writing of such sale, the terms thereof and the closing date
         thereof, and shall provide additional written notification promptly
         upon any amendment or modification to any thereof, all of which terms
         shall apply equally to all Stockholders except that no Other
         Stockholder shall be required to make any representations, warranties
         or covenants, or bear any liability, with respect to the Company or the
         Company's business or with respect to any other Stockholder;

                  (iv) at the closing of such sale, each of the Stockholders
         shall deliver certificates evidencing the Common Stock, options and
         warrants then held by it and to be sold in such sale, duly endorsed for
         transfer or accompanied by stock powers executed in blank, against
         payment of the purchase price therefor by wire transfer to the account
         or accounts specified by such Stockholder; and

                  (v) the Other Stockholders shall not be obligated to
         participate in such sale if all of the WCAS Purchasers shall not have
         concurrently sold all or the same percentage of their shares of Common
         Stock, options and/or warrants to be sold by them in connection with
         such sale.

                  SECTION 5.  Preemptive Rights.

                  (a) The Company hereby grants to each Stockholder the right to
purchase such Stockholder's Proportionate Percentage (as hereinafter defined) of
any future Eligible Offering (as hereinafter defined). For the purposes of this
Section 5, the following terms shall have the meanings set forth below:

                  "Proportionate Percentage" means, with respect to any
         Stockholder as of any date, the result (expressed as a percentage)
         obtained by dividing (i) the number of shares of Common Stock owned by
         such Stockholder as of such date by (ii) the total number of shares of
         Common Stock outstanding as of such date.

                  "Eligible Offering" means an offer by the Company to sell to
         any person or persons (including any of the Stockholders) for cash,
         cash equivalents or indebtedness any equity securities of the Company,
         or any security convertible into or exchangeable for, or carrying
         rights or options to purchase, equity securities of the Company, other
         than an offering by the Company:

                           (i) of shares of Common Stock or options to purchase
                  shares of Common Stock in connection with or pursuant to any
                  stock option or stock
                              

                                       7

                  purchase plan approved by the Board of Directors of the 
                  Company to full-time employees, officers, directors, 
                  consultants and/or advisors to the Company or its
                  subsidiaries;

                           (ii) in a public offering (a "Public Offering")
                  registered under the Securities Act.

                  (b) The Company shall, before issuing any securities pursuant
to an Eligible Offering, give written notice thereof to each Stockholder. Such
notice shall specify the security or securities the Company proposes to issue,
the proposed date of issuance, the consideration that the Company intends to
receive therefor and all other material terms and conditions of such proposed
issuance. For a period of 15 days following the date of such notice, each
Stockholder shall be entitled, by written notice to the Company, to elect to
purchase all or any part of such Stockholder's Proportionate Percentage of the
securities being sold in the Eligible Offering; provided, however, that if two
or more securities shall be proposed to be sold as a "unit" in an Eligible
Offering, any such election must relate to such unit of securities. To the
extent that elections pursuant to this Section 5(b) shall not be made with
respect to any securities included in an Eligible Offering within such 15-day
period, then the Company may issue such securities, but only for consideration
not less than, and otherwise on no less favorable terms to the Company than,
those set forth in the Company's notice and only within 60 days after the end of
such 15-day period. In the event that any such offer is accepted by a
Stockholder or Stockholders, the Company shall sell to such Stockholder or
Stockholders, and such Stockholder or Stockholders shall purchase from the
Company, for the consideration and on the terms set forth in the notice as
aforesaid, the securities that such Stockholder or Stockholders shall have
elected to purchase.

                  SECTION  6.  Right of First Offer.

                  (a) If any Blackstone Purchaser (for purposes of this Section
6, a "Seller") desires to sell, exchange or in any other manner dispose of
(other than in a manner permitted by Section 6(d) hereof) any shares of capital
stock of the Company held by it, then such Seller shall give to the Company a
written notice (a "Notice of Desire to Sell") which shall set forth in
reasonable detail the class and number of shares of capital stock which it
desires to sell and may, if the Seller so chooses to specify, set forth any
other terms and conditions of the desired disposition. The Company shall deliver
such Notice of Desire to Sell to each of the WCAS Purchasers promptly upon
receipt thereof. A Seller may deliver a Notice of Desire to Sell whether or not
such Seller has received an offer from a third party to purchase such shares of
capital stock.

                  (b) The WCAS Purchasers shall have the right, exercisable upon
written notice to the Seller within 15 days after receipt of any Notice of
Desire to Sell (the "Offer Notice"), to offer to purchase any or all shares of
capital stock proposed to be sold by the Seller at a purchase price equal to the
proposed purchase price specified in the Notice of Desire to Sell if so
specified, or as proposed in the Offer Notice if not specified in the Notice of
Desire to Sell,

                  

                                       8
<PAGE>
 
and otherwise on the terms and conditions specified in the Notice of Desire
to Sell to the extent so specified and any additional terms and conditions
proposed in the Offer Notice (collectively, including with respect to
purchase price, the "Offer Terms"). Each Offer Notice shall state the
number of shares to be purchased by the WCAS Purchasers delivering such
Offer Notice (the "Purchasing Stockholders") and that the Purchasing
Stockholders will purchase such shares within 45 days thereafter (or such
longer period as is necessary to obtain any necessary consents or approvals
or to otherwise comply with applicable law). In the event that more than
one WCAS Purchaser exercises its right to offer to purchase pursuant to
this paragraph (b), the allocation among such WCAS Purchasers of any shares
actually sold pursuant to this paragraph (b) shall be as agreed by such
WCAS Purchasers.

                  (c) If the WCAS Purchasers deliver, within the period
specified in paragraph (b) above, an Offer Notice with respect to capital stock
that is the subject of the Notice of Desire to Sell, the Seller shall be
entitled to sell such capital stock to such Purchasing Stockholders, on the
Offer Terms within the 45-day period specified in paragraph (b) above (or such
longer period as is necessary to obtain any necessary consents or approvals or
to otherwise comply with applicable law). Following the period specified in
paragraph (b) above, the Seller may (subject to any other applicable
restrictions hereunder) transfer such capital stock to any third party; provided
that, if an Offer Notice with respect to all of such shares of capital stock was
delivered within the 15 day period specified in paragraph (b) above, the Seller
may not sell such shares to such third party on material terms which are the

                  SECTION 8.  Right and Option to Repurchase Shares of Common 
Stock From Management Purchasers Upon Termination of Employment.

                  (a) In the event that any Management Purchaser ceases to be
employed by the Company or Centennial or any subsidiary thereof on a full-time
basis for any reason (including, without limitation, as a result of his death,
disability, incapacity, retirement, resignation or dismissal with or without
"cause" (as defined below)), the WCAS Purchasers shall have the right and
option, but not the obligation, to purchase from such Management Purchaser (or
in the case of his death, his legal representative), in such proportions as the
WCAS Purchasers shall agree, any or all of the shares of Common Stock purchased
by such Management Purchaser pursuant to the Purchase Agreement (the "Repurchase
Shares"). In the event that the WCAS Purchasers exercise such right and option,
the WCAS Purchasers shall pay to such Management Purchaser as the purchase price
for such Repurchase Shares (the "Purchase Price"), an amount per share equal to
the fair market value thereof as of the date such Management Purchaser ceased to
be so em ployed by the Company or Centennial or any subsidiary thereof, such
fair market value to be determined in good faith by the Board on a basis
consistent with the manner of determining the


         

                                       11
<PAGE>
 
fair market value of the Common Stock for purposes of offering of the Company's
Common Stock to equity investors (the "Fair Market Value").

                  (b) The WCAS Purchasers may exercise the right and option
described in Section 8(a) above by giving such Management Purchaser (or in the
case of his death, his legal representative) a written notice of election to
purchase at any time within 60 days after the date such employment ceases, which
notice of election shall specify the number of shares to be purchased by each
electing WCAS Purchaser and the Purchase Price for such shares. The closing for
the purchase by the WCAS Purchasers of Repurchase Shares pursuant to Section
8(a) will take place at the offices of Welsh, Carson, Anderson & Stowe on the
date specified in the written notice of election with respect to such shares,
which date shall be a business day not later than 60 days (or such longer period
as is necessary to obtain any necessary consents or approvals or to otherwise
comply with applicable law) after the date such notice is given. At such
closing, the Management Purchaser (or in the case of his death, his legal
representative) will deliver such shares, duly endorsed for transfer, against
payment in cash of the Purchase Price thereof.

                  (c) In the event that the WCAS Purchasers choose not to
exercise their rights and options under Section 8(a) hereof within the 60 day
period referred to in Section 8(b), the Company shall have the right and option,
but not the obligation, to purchase from the Management Purchaser whose
employment was terminated (or in the case of his death, his legal
representative) any or all of the Repurchase Shares. In the event that the
Company exercises such right and option, the purchase price for such shares
shall be the Purchase Price determined in accordance with Section 8(a).

                  (d) The Company may exercise the right and option described in
Section 8(c) above by giving such Management Purchaser (or in the case of his
death, his legal representative) a written notice of election to purchase at any
time within 30 days after the expiration of the 60 day period referred to in
Section 8(b) above, which notice of election shall specify the number of
Repurchase Shares to be purchased and the Purchase Price for such shares. The
closing for the purchase by the Company of Repurchase Shares pursuant to Section
8(c) will take place at the offices of the Company on the date specified in the
written notice of election with respect to such shares, which date shall be a
business day not later than 60 days (or such longer period as is necessary to
obtain any necessary consents or approvals or to otherwise comply with
applicable law) after the date such notice is given. At such closing, the
Management Purchaser (or in the case of his death, his legal representative)
will deliver such shares, duly endorsed for transfer, against payment in cash of
the Purchase Price thereof.

                  SECTION 9. Financial and Other Information. For so long as any
Stockholder holds at least 25% of the Common Stock held by it as of the date
hereof, the Company shall furnish to such Stockholder:

                  (i) within 90 days after the end of each fiscal year of the
         Company, a consolidated balance sheet of the Company and its

         regarding the opera tions, business, affairs and financial condition of
         the Company or any subsidiary as such Stockholder may reasonably
         request, subject to such confidentiality agreements as the Company may
         reasonably request.

                  SECTION 10. Legend on Stock Certificates. Each certificate
representing shares of Common Stock owned by any Stockholder shall conspicuously
bear the following legend until such time as the shares represented thereby are
no longer subject to the provisions hereof:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO

        OF JANUARY 7, 1999, AMONG THE COMPANY AND THE OTHER PARTIES
        THERETO. COPIES MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST
        MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
        COMPANY."


                               

                                       13

                  The Company covenants that it shall keep a copy of this
Agreement on file at the address listed in Section 19 for the purpose of
furnishing copies to the holders of record of shares of Common Stock.

                  SECTION 11. Duration of Agreement. (a) This Agreement (other
than the provisions of Sections 1, 10, 11(b) and 15 through 25) shall terminate
upon the earlier to occur of (i) the tenth anniversary of the date hereof or
(ii) the consummation of (x) a Public Offering by the Company of Common Stock
having an aggregate offering price to the public of not less than $50,000,000,
and (y) the sale, transfer or other disposition (including a distribution by a
limited partnership to its partners) by either the WCAS Purchasers or the
Blackstone Purchasers to persons or entities not required to become parties
hereto of at least 50% of the shares of Common Stock held by the WCAS Purchasers
or the Blackstone Purchasers, as the case may be, on the date hereof.

                  (b) The provisions of Sections 1, 10, 11(b) and 15 through 25
shall terminate upon the earlier to occur of (i) the tenth anniversary of the
date hereof or (ii) the consummation of (x) a Public Offering by the Company of
Common Stock having an aggregate offering price to the public of not less than
$50,000,000, and (y) the sale, transfer or other disposition (including a
distribution by a limited partnership to its partners) by both of the WCAS

payment of such monitoring fees is prohibited by any provision of any credit
agreement or other debt instrument, the Company shall use commercially
reasonable efforts to cause the lender or holder of such debt instrument to
waive any such prohibition. If, despite such efforts, such lender or holder is
unwilling to permit the Company to pay such monitoring fee, then any amounts not
so paid shall accrue and shall bear interest at the rate of 13% per annum until

the legal, valid and binding obligation of such Stockholder, enforceable in
accordance with its terms.

                  (c) The shares of Common Stock listed opposite the name of
such Stockholder on Schedule I, Schedule II, Schedule III or Schedule IV hereof,
as the case may be, constitute all the shares of Common Stock of the Company

                  SECTION 14. Representations and Warranties by the Company. The
Company hereby incorporates by reference and makes the representations and
warranties set forth in the Purchase Agreement, to the extent applicable to this

assigns any legal or equitable right, remedy or claim under or in respect of
this Agreement or any provision herein contained, this Agreement and all
conditions and provisions hereof being intended to be and being for the sole and
exclusive benefit of the parties hereto and their respective successors and
permitted assigns. Notwithstanding anything in this Section 17 to the contrary,
subject to compliance with the terms of this Agree ment, each Stockholder shall
have the right to assign its interests hereunder in whole or in part to any
transferee of the Common Stock held by such Stockholder in compliance with this
Agree ment; provided, however, that such transferee shall agree in writing with
the parties hereto to be bound by, and to comply with, all applicable provisions
of this Agreement and to be deemed to be a Stockholder for purposes of this
Agreement (it being understood that for purposes


                                       15

Agreement in the manner provided above so long as such transferee is, with

clause (i) or (iii) of Section 3(d). Any Stockholder may assign to any of its
affiliates which are also Stockholders all or any part of its tag-along rights
with respect to a particular proposed sale pursuant to Section 3 or its rights
to purchase securities pursuant to Section 5; provided the aggregate number of
shares of Common Stock to which such rights apply with respect to all such
affiliated Stockholders, taken as a whole, shall not be increased thereby.
Except as expressly permitted hereby, each party's rights and obligations under
this Agreement shall not be subject to assignment or delegation by any party
hereto, and any attempted assignment or delegation in violation hereof shall be
null and void ab initio.

                  SECTION 18. Notice of Transfer. To the extent that any

covenants, stipulations, promises and agreements in this Agreement contained by
or on behalf of any party shall bind its successors and permitted assigns,
whether so expressed or not. Without limiting the generality of the foregoing,
upon the consummation of the merger contemplated by the Merger Agreement (the
"Merger"), the corporation that survives the Merger shall succeed to all obliga
tions of the Company set forth herein and, immediately following such Merger,
shall execute and deliver to each Stockholder a supplement hereto in form and
substance reasonably acceptable to each Stockholder acknowledging that it is
bound by all such obligations of the Company.

                  SECTION 22. Counterparts. This Agreement may be executed in
any number of counterparts, and each such counterpart hereof shall be deemed to
be an original instrument, but all such counterparts together shall constitute
but one agreement.

                  SECTION 23. Changes in Common Stock. If, and as often as,
there are any changes in the Common Stock by way of stock split, stock dividend,
combination or reclassification, or through merger, consolidation,
reorganization or recapitalization, or by any other means, appropriate
adjustment shall be made in the provisions hereof as may be required so that the


                           
                                       17

rights and privileges granted hereby shall continue with respect to the Common
Stock as so changed.


                  SECTION 24. Specific Performance. Each party hereto agrees
that a remedy at law for any breach or threatened breach by such party of this
Agreement would be inadequate and therefore agrees that any other party hereto
shall be entitled to specific performance of this Agreement in addition to any
other available rights and remedies in case of any such breach or threatened
breach.

                 SECTION 25. Governing Law. This Agreement shall be governed by,
enforceable under, and construed in accordance with the laws of the State of
Delaware.



                                       18

                  IN WITNESS WHEREOF, each of the parties hereto has executed
this Agreement as a sealed instrument, all as of the day and year first above
written.
