         any related constraints on operating activities and any potential
         liabilities to third parties) which would, singly or in the aggregate,

         Issuers reasonably believe are prudent and customary in the businesses
         in which they are engaged; none of the Company, Centennial Cellular,
         Centennial PR or any such subsidiary has been refused any insurance
         coverage sought or applied for, except for any such refusal that would
         not reasonably be expected to have a material adverse effect on the
         Issuers and their subsidiaries, taken as a whole; and none of the
         Company, Centennial Cellular, Centennial PR or any such subsidiary has
         any reason to believe that it will not be able to renew its existing
         insurance coverage as and when such coverage expires or to obtain
         similar coverage from similar insurers as may be necessary to continue
         its business at a cost that would not reasonably be expected to have a
         material adverse effect on the Issuers and their subsidiaries, taken as
         a whole, except as described in the Final Memorandum.

<PAGE>

                  (y)      The Issuers and each of their subsidiaries keep
         accurate books and records reflecting their respective assets and
         maintain a system of internal accounting controls sufficient to provide
         reasonable assurance that (i) transactions are executed in accordance
         with management's general or specific authorizations; (ii) transactions
         are recorded as necessary to permit preparation of consolidated
         financial statements in conformity with generally accepted accounting
         principles and to maintain asset accountability; (iii) access to assets
         is permitted only in accordance with management's general or specific
         authorization; and (iv) the recorded accountability for assets is
         compared with the existing assets at reasonable intervals and
         appropriate action is taken with respect to any differences.

                  (z)      No labor dispute with the employees of the Company,
         Centennial Cellular, Centennial PR or their Significant Subsidiaries
         exists or, to the knowledge of the Issuers, is imminent; none of the
         Company, Centennial Cellular, Centennial PR or any of their
         subsidiaries is aware of any existing or imminent labor disturbance by
         the employees of any of the Company's, Centennial Cellular's,
         Centennial PR's or any of their subsidiaries' principal suppliers,
         manufacturers, customers or contractors which, in either case, would
         reasonably be expected to result in a material adverse effect on the
         Issuers and their subsidiaries, taken as a whole, except as described
         in the Final Memorandum.

                  (aa)     The Issuers and their Significant Subsidiaries have
         good and marketable title to all material real property owned by them
         and good title to all other material properties owned by them, in each
         case, free and clear of all mortgages, pledges, liens, security
         interests, claims, restrictions or encumbrances of any kind (other than
         Permitted Liens, as defined in the Indenture) except such as would not,
         singly or in the aggregate, reasonably be expected to materially affect
         the value of such property and would not interfere with the use made
         and proposed to be made of such property by the Company, Centennial
         Cellular, Centennial PR or any of their Significant Subsidiaries,
         except for any such interference that would not reasonably be expected
         to have a material adverse effect on the Issuers and their
         subsidiaries, taken as a whole; all of the leases and subleases
         material to the business of the Issuers and their subsidiaries,
         considered as one enterprise, and under which the Company, Centennial
         Cellular, Centennial PR or any of their subsidiaries hold properties,
         are in full force and effect, and none of the Company, Centennial
         Cellular, Centennial PR or any of their subsidiaries, has any notice of
         any material claim of any sort that has been asserted by anyone adverse
         to the rights of the Company, Centennial Cellular, Centennial PR or any
         of their subsidiaries under any of these leases or subleases, or
         affecting or questioning the rights of the Company, Centennial
         Cellular, Centennial PR or any of their subsidiaries to the continued
         possession of the leased or subleased premises under any such lease or
         sublease, except in each case to the extent such would not reasonably
         be expected to have a material adverse effect on the Issuers and their
         subsidiaries, taken as a whole.

                  (bb)     All material United States federal income tax returns
         of the Issuers and their subsidiaries required by law to be filed have
         been filed and all taxes shown by such returns or otherwise assessed,
         which are due and payable, have been paid, except assessments against
         which appeals have been or will be promptly taken and as to which
         adequate reserves have been provided. The Issuers and their
         subsidiaries have filed all

<PAGE>

         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 the failure to file such returns would not reasonably be
         expected to result in a material adverse effect on the Issuers and
         their subsidiaries, taken as a whole, and have paid all taxes due
         pursuant to such returns or pursuant to any assessment received by the
         Issuers and their subsidiaries, except for such 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 the Issuers and their subsidiaries in respect
         of all federal, state, local and foreign tax liabilities of the Issuers
         and each subsidiary for any years not finally determined are adequate
         to meet any assessments or reassessments for additional income tax for
         any years not finally determined, except to the extent of any
         inadequacy that would not reasonably be expected to result in a
         material adverse effect on the Issuers and their subsidiaries, taken as
         a whole.

                  (cc)     Except as disclosed in the Final Memorandum, there
         are no contracts, agreements or understandings between the Issuers with
         any person that would give rise to a claim against the Issuer or the
         Initial Purchasers for a brokerage commission, finder's fee or other
         like payment in connection with this offering.

                  (dd)     There are no persons or entities with registration or
         other similar rights to require the Issuers to include any securities
         in any registration statement filed pursuant to the Registration Rights
         Agreement or in any offering made pursuant to any such registration
         statement.

                  (ee)     Since the date as of which information is given in
         the Final Memorandum through the Closing Date (as defined herein), and
         except as may otherwise be disclosed in the Final Memorandum, the
         Issuers have not (i) issued or granted any securities other than the
         Securities or shares issued pursuant to existing employee benefit
         plans, qualified stock option plans or other employee compensation
         plans or pursuant to outstanding options, rights or warrants, (ii)
         incurred any material liability or obligation, direct or contingent,
         other than liabilities and obligations which were incurred in the
         ordinary course of business, (iii) entered into any material
         transaction which would be required to be disclosed in the Final
         Memorandum or (iv) declared or paid any dividend on its capital stock.

                  Each certificate signed by any officer of an Issuer and
         delivered to the Initial Purchasers or their counsel shall be deemed to
         be a representation and warranty by such Issuer to the Initial
         Purchasers as to the matters covered thereby.

<PAGE>

                  2.       Agreements to Sell and Purchase. The Issuers hereby

                  (i)      such Initial Purchaser understands that no action has
         been or will be taken in any jurisdiction by the Company, Centennial
         Cellular or Centennial PR that would permit a public offering of the
         Securities, or possession or distribution of either Memorandum or any
         other offering or publicity material relating to the Securities, in any
         country or jurisdiction where action for that purpose is required;

<PAGE>

                  (ii)     such Initial Purchaser will comply with all
         applicable laws and regulations in each jurisdiction in which it
         acquires, offers, sells or delivers Securities or has in its possession
         or distributes either Memorandum or any such other material, in all
         cases at its own expense;

                  (iii)    the Securities have not been registered under the
         Securities Act and may not be offered or sold within the United States
         or to, or for the account or benefit of, U.S. persons except in
         accordance with Rule 144A or Regulation S under the Securities Act or
         pursuant to another exemption from the registration requirements of the
         Securities Act;

                  (iv)     such Initial Purchaser has offered the Securities and
         will offer and sell the Securities (A) as part of their distribution at
         any time and (B) otherwise until 40 days after the later of the
         commencement of the offering and the Closing Date, only in accordance
         with Rule 903 of Regulation S or as otherwise permitted in Section
         7(a); accordingly, neither such Initial Purchaser, its Affiliates nor
         any persons acting on its or their behalf have engaged or will engage
         in any directed selling efforts (within the meaning of Regulation S)
         with respect to the Securities, and any such Initial Purchaser, its
         Affiliates and any such persons have complied and will comply with the
         offering restrictions requirement of Regulation S;

                  (v)      such Initial Purchaser (A) has not offered or sold
         and, prior to the date six months after the Closing Date, will not
         offer or sell any Securities to persons in the United Kingdom except to
         persons whose ordinary activities involve them in acquiring, holding,
         managing or disposing of investments (as principal or agent) for the
         purposes of their businesses or otherwise in circumstances which have
         not resulted and will not result in an offer to the public in the
         United Kingdom within the meaning of the Public Offers of Securities
         Regulations 1995; (B) has complied and will comply with all applicable
         provisions of the Financial Services and Markets Act 2000 (the "FSMA")
         with respect of anything done by it in relation to the Securities in,
         from or otherwise involving the United Kingdom, and (C) will only
         communicate or cause to be communicated any invitation or inducement to
         engage in investment activity (within the meaning of section 21 of the
         FSMA) received by it in connection with the issue or sale of the
         Securities in circumstances in which section 21(1) of the FSMA does not
         apply to the Company, Centennial Cellular or Centennial PR;

                  (vi)     such Initial Purchaser understands that the
         Securities have not been and will not be registered under the
         Securities and Exchange Law of Japan, and represents that it has not
         offered or sold, and agrees not to offer or sell, directly or
         indirectly, any Securities in Japan or for the account of any resident
         thereof except pursuant to any exemption from the registration
         requirements of the Securities and Exchange Law of Japan and otherwise
         in compliance with applicable provisions of Japanese law; and

                  (vii)    such Initial Purchaser agrees that, at or prior to
         confirmation of sales of the Securities, it will have sent to each
         distributor, dealer or person receiving a selling concession, fee or
         other remuneration that purchases Securities from it during the
         restricted period a confirmation or notice to substantially the
         following effect:

<PAGE>

                  "The Securities covered hereby have not been registered under
         the U.S. Securities Act of 1933 (the "Securities Act") and may not be
         offered and sold within the United States or to, or for the account or
         benefit of, U.S. persons (i) as part of their distribution at any time
         or (ii) otherwise until 40 days after the later of the commencement of
         the offering and the closing date, except in either case in accordance
         with Regulation S (or Rule 144A if available) under the Securities Act.
         Terms used above have the meaning given to them by Regulation S."

                  Terms used in this Section 7(b) have the meanings given to
         them by Regulation S.

                  8.       Indemnity and Contribution. (a) The Company,
Centennial Cellular and Centennial PR agree, jointly and severally, to indemnify
and hold harmless each Initial Purchaser and each person, if any, who controls
any Initial Purchaser within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act, and each affiliate of any Initial
Purchaser within the meaning of Rule 405 under the Securities Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in either
Memorandum (as amended or supplemented if the Issuers shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact necessary to make the statements
therein in the light of the circumstances under which they were made not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to any Initial Purchaser furnished to
the Issuers in writing by such Initial Purchaser through you expressly for use
therein; provided, however, that the foregoing indemnity agreement with respect
to losses, claims, damages or liabilities shall not inure to the benefit of any
Initial Purchaser (or any person controlling any Initial Purchaser) with respect
to any losses, claims, damages or liabilities arising out of or based upon (x)
any untrue statement or alleged untrue statement of any material fact in the
Preliminary Memorandum or (y) the omission or alleged omission to state in the
Preliminary Memorandum a material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, if: (1) the Company furnished sufficient copies of the Final
Memorandum on a timely basis to permit delivery of the Final Memorandum to all
persons purchasing Securities from the Initial Purchasers in the initial resale
of such Securities (such persons being the "Initial Resale Purchasers") at or
prior to the written confirmation of the sale of the Securities to such person;
(2) the Initial Resale Purchaser asserting such losses, claims, damages or
liabilities purchased Securities in the initial resale from the Initial
Purchasers and a copy of the Final Memorandum was not sent or given by or on
behalf of such Initial Purchaser to such Initial Resale Purchaser; and (3) the
Final Memorandum would have cured the defect giving rise to such losses, claims,
damages or liabilities. The term "Final Memorandum" as used for purposes of
Section 8(a) herein shall mean the Final Memorandum, as amended or supplemented
if the Issuers shall have furnished any amendments or supplements thereto.

                  (b)      Each Initial Purchaser agrees, severally and not
jointly, to indemnify and hold harmless the Issuers, their directors, their
officers and each person, if any, who controls any of the Issuers within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act to the same extent as the foregoing indemnity from the Issuers to such
Initial

<PAGE>

Purchaser, but only with reference to information relating to such Initial
Purchaser furnished to the Issuers in writing by such Initial Purchaser through
you expressly for use in either Memorandum or any amendments or supplements
thereto, where such information is actually included in either Memorandum and or
any amendment or supplement thereto. Additionally, each Initial Purchaser
acknowledges that the indemnity contained in (a) above shall not operate to
indemnify the Initial Purchasers regarding the matters described in the prior
sentence.

                  (c)      In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the
"INDEMNIFIED PARTY") shall promptly notify the person against whom such
indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the reasonable fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed to the retention of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
indemnifying party shall not, in respect of the legal expenses of any
indemnified party in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable fees and expenses of more
than one separate firm of legal counsel (in addition to any local counsel) for
all such indemnified parties and that all such fees and expenses shall be
reimbursed as they are incurred. Such firm shall be designated in writing by the
Representatives, in the case of parties indemnified pursuant to Section 8(a),
and by the Issuers, in the case of parties indemnified pursuant to Section 8(b).
The indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. Notwithstanding the foregoing sentence, if at
any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second and third sentences of this paragraph, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

                  (d)      To the extent the indemnification provided for in
Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each indemnifying party under such paragraph, in lieu of

<PAGE>

indemnifying such indemnified party thereunder, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (i) in such proportion as is appropriate to reflect the
relative benefits received by the Issuers on the one hand and the Initial
Purchasers on the other hand from the offering of the Securities or (ii) if the
allocation provided by clause 8(d)(i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause 8(d)(i) above but also the relative fault of the Issuers
on the one hand and of the Initial Purchasers on the other hand in connection
with the statements or omissions that resulted in such losses, claims, damages
or liabilities, as well as any other relevant equitable considerations. The
relative benefits received by the Issuers on the one hand and the Initial
Purchasers on the other hand in connection with the offering of the Securities
shall be deemed to be in the same respective proportions as the net proceeds
from the offering of the Securities (before deducting expenses) received by the
Issuers and the total discounts and commissions received by the Initial
Purchasers in respect thereof, bear to the aggregate offering price of the
Securities. The relative fault of the Issuers on the one hand and of the Initial
Purchasers on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuers 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 Initial Purchasers' respective obligations to
contribute pursuant to this Section 8 are several in proportion to the
respective principal amount of Securities they have purchased hereunder, and not
joint.

                  (e)      The Issuers and the Initial Purchasers agree that it
would not be just or equitable if contribution pursuant to this Section 8 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 that does
not take account of the equitable considerations referred to in Section 8(d).
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in Section 8(d) shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 8, no Initial Purchaser shall be required to contribute any amount in
excess of the amount by which the total price at which the Securities resold by
it in the initial placement of such Securities were offered to investors exceeds
the amount of any damages that 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 Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

                  (f)      The indemnity and contribution provisions contained
in this Section 8 and the representations, warranties and other statements of
the Issuers contained in this Agreement shall remain operative and in full force
and effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of any Initial Purchaser or any person
controlling any Initial Purchaser or any affiliate of any Initial Purchaser or
by or on behalf of the Company, Centennial Cellular or Centennial PR, their
officers or directors or any person

<PAGE>

controlling the Company, Centennial Cellular or Centennial PR and (iii)
acceptance of and payment for any of the Securities.

                  (g)      The only information furnished by the Initial
Purchasers to the Issuers for purposes of Section 8(a) and (b) hereof, to the
extent such statements relate to the Initial Purchasers, are (i) the names of
the Initial Purchasers set forth on (A) the front and back cover pages of the
Final Memorandum and (B) in the section of the Final Memorandum captioned "Plan
of Distribution"; (ii) statements set forth in the fifth full paragraph
appearing under the caption "Plan of Distribution" on page 152 of the Final
Memorandum, relating to the price at which the Initial Purchasers will offer the
Senior Notes; (iii) the first sentence of the sixth paragraph under the caption
"Plan of Distribution" on page 152 of the Final Memorandum, relating to the
Initial Purchaser's intention to sell the Senior Notes in reliance on Rule 144A
and Regulation S under the Securities Act; (iv) the sixth sentence of the tenth
paragraph under the caption "Plan of Distribution" on page 153 of the Final
Memorandum, relating to market-making activities of the Initial Purchasers; and
(v) the first three sentences of the twelfth paragraph under the caption "Plan
of Distribution" on page 153 of the Final Memorandum, relating to
over-allotment, stabilizing and covering transactions and penalty bids.

                  9.       Termination. This Agreement shall be subject to
termination by notice given by you to the Issuers, if subsequent to the
execution and delivery of this Agreement, there shall have occurred (i) any
change, or any development or event involving a prospective change, in the
condition (financial or other), business, properties or results of operations of
the Company and its subsidiaries taken as one enterprise which, in the judgment
of Lehman Brothers Inc. and Credit Suisse First Boston LLC is material and
adverse and makes it impractical or inadvisable to proceed with the completion
of the offering or the sale of and payment for the Securities; (ii) any
downgrading in the rating of any debt securities of the Issuers by any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Securities Act), or any public announcement that any
such organization has under surveillance or review its rating of any debt
securities of the Issuers (other than an announcement with positive implications
of a possible upgrading, and no implication of a possible downgrading, of such
rating) or any announcement that the Company, Centennial Cellular or Centennial
PR has been placed on negative outlook which, in the judgment of the Underwriter
makes it impracticable or inadvisable to proceed with the offering, sale or
delivery of the Notes on the terms and in the manner contemplated in the
Memorandum; (iii) any change in U.S. or international financial, political or
economic conditions or currency exchange rates or exchange controls as would, in
the judgment of the Representatives, be likely to prejudice materially the
success of the proposed issue, sale or distribution of the Securities, whether
in the primary market or in respect of dealings in the secondary market; (iv)
any material suspension or material limitation of trading in securities
generally on the New York Stock Exchange or any setting of minimum prices for
trading on such exchange, or any suspension of trading of any securities of the
Issuers on any exchange or in the over-the-counter market; (v) any banking
moratorium declared by U.S. Federal or New York authorities; (vi) any major
disruption of settlements of securities or clearance services in the United
States or (vii) any attack on, outbreak or escalation of hostilities or act of
terrorism involving the United States, any declaration of war by Congress or any
other national or international calamity or emergency if, in the judgment of
Lehman Brothers Inc. and Credit Suisse First Boston LLC, the effect of any such
attack, outbreak, escalation, act, declaration, calamity or emergency makes it
impracticable or inadvisable to proceed with

<PAGE>

completion of the offering or sale of and payment for the Securities in the
manner contemplated by the Final Memorandum.

                  10.      Effectiveness; Defaulting Initial Purchasers. This
Agreement shall become effective upon the execution and delivery hereof by the
parties hereto.

                  If, on the Closing Date, any one or more of the Initial
Purchasers shall fail or refuse to purchase Securities that it or they have
agreed to purchase hereunder on such date, and the aggregate principal amount of
Securities which such defaulting Initial Purchaser or Initial Purchasers agreed
but failed or refused to purchase is not more than one-tenth of the aggregate
principal amount of Securities to be purchased on such date, the other Initial
Purchasers shall be obligated severally in the proportions that the principal
amount of Securities set forth opposite their respective names in Schedule I
bears to the aggregate principal amount of Securities set forth opposite the
names of all such non-defaulting Initial Purchasers, or in such other
proportions as you may specify, to purchase the Securities which such defaulting
Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase
on such date; provided that in no event shall the principal amount of Securities
that any Initial Purchaser has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 10 by an amount in excess of one-ninth of
such principal amount of Securities without the written consent of such Initial
Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers
shall fail or refuse to purchase Securities which it or they have agreed to
purchase hereunder on such date and the aggregate principal amount of Securities
with respect to which such default occurs is more than one-tenth of the
aggregate principal amount of Securities to be purchased on such date, and
arrangements satisfactory to you and the Issuers for the purchase of such
Securities are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of any non-defaulting Initial Purchaser
or of the Issuers. In any such case either you or the Issuers shall have the
right to postpone the Closing Date, but in no event for longer than seven days,
in order that the required changes, if any, in the Final Memorandum or in any
other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Initial Purchaser from liability in
respect of any default of such Initial Purchaser under this Agreement.

                  If this Agreement shall be terminated by the Initial
Purchasers, or any of them, because of any failure or refusal on the part of the
Company, Centennial Cellular or Centennial PR to comply with the terms or to
fulfill any of the conditions of this Agreement, or if for any reason the
Company, Centennial Cellular or Centennial PR shall be unable to perform its
obligations under this Agreement, the Issuers will reimburse the Initial
Purchasers or such Initial Purchasers as have so terminated this Agreement with
respect to themselves, severally, for all reasonable fees and disbursements of
their counsel in connection with this Agreement or the offering contemplated
hereunder, provided that the Issuers shall have no obligation to reimburse any
Initial Purchaser that has breached its obligations hereunder for any such
out-of-pocket expenses.

                  11.      Notices. All notices and other communications under
this Agreement shall be in writing and mailed, delivered or sent by facsimile

number of counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were upon the same instrument.
