"Employee") and Centennial Communications Corp., and any and all of its
affiliates, subsidiaries, predecessors, successors and assigns and any of its

                                    RECITALS

      A.    Employee resigned from the employ of Employer effective April 1,
            2002 (the "Resignation Date").

      B.    Employee and Employer wish to permanently resolve any and all claims
            and disputes, whether known or unknown, which exist or may exist on
            Employee's behalf, including but not limited to any claims arising
            out of Employee's employment with Employer and the termination of
            that employment.

      NOW THEREFORE, in exchange for the consideration, covenants and promises
contained herein, the receipt and sufficiency of which is hereby acknowledged,
Employer and Employee agree as follows:

      1.    Employer shall pay Employee the amounts set forth on Exhibit 1
            hereto, subject to applicable tax withholdings. Employee
            acknowledges that Employee has been paid for any and all allowances
            or payments due and owing to Employee at the Resignation Date.
            Except as expressly provided herein, Employee acknowledges that he
            is not entitled to receive any vacation accrual or other payments or
            benefits after the Resignation Date, other than customary
            reimbursement of business expenses through the Resignation Date.

      2.    Effective on the Resignation Date, Employee will cease to
            participate in any Employer sponsored plans and benefits, including
            without limitation any employee stock option plan, employee stock
            purchase plan and 401(k) plan. All funds previously contributed to

            date hereof to exercise any previously vested stock options pursuant
            to the terms of Employer's Stock Option and Restricted Stock
            Purchase Plan and Employee's relevant stock option agreement.

      3.    Employee hereby irrevocably fully waives, releases, acquits and
            forever discharges Employer from any and all claims, charges,
            complaints, liabilities, allegations, demands, injuries, debts,
            breaches, violations, acts or omissions and causes of action, known

            laws, including without limitation, Puerto Rico and Dominican
            Republic laws (collectively, "Claims").

            he is the sole owner of any and all Claims that he is relinquishing
            by executing this Agreement and that no other person has any
            interest in any such Claims. Employee acknowledges that he has had
            the benefit of advice of competent legal counsel with respect to the
            decision to enter into this Agreement.

      5.    Except as set forth in Schedule 1, Employee represents and warrants
            to Employer that on or prior to the date hereof, Employee has (i)
            returned to Employer all keys, vehicles, computers, telephones,
            beepers, inventory and/or any other property of Employer including
            any and all confidential and proprietary information that is in
            Employee's possession or control and will make no further use of
            same after the date hereof and (ii) repaid Employer all amounts

            professional advisors to whom the disclosure is necessary to
            accomplish the purposes for which such party has contacted such
            advisors.

      8.    Employee acknowledges that due to the position Employee has occupied
            and the responsibilities Employee has had while employed by
            Employer, Employee has received confidential and proprietary
            information concerning Employer. Employee hereby promises and agrees
            that, unless compelled by legal process, Employee will not disclose

            parties.

      9.    Employee agrees that he will not directly or indirectly induce or
            attempt to induce any employee of the Employer to leave the employ
            of the Employer or in any way interfere with the relationship
            between the Employer and any employee thereof. Employee agrees that
            he will not now, or in the future, deliberately disrupt, damage,
            injure or interfere with the business of Employer.

      10.   Employee agrees that he will not now, or in the future, make any
            disparaging statements (whether oral or written) concerning
            Employer.

      11.   In exchange for the consideration to be received by Employee
            hereunder, which Employee expressly acknowledges is sufficient and
            satisfactory, Employee agrees that for a period of one year after
            the expiration of the Consulting Agreement attached hereto as
            Exhibit 2, Employee agrees that he will not, directly or indirectly,
            own, manage, control, participate in, consult with, render services
            for or in any manner engage in any business in the Service Area (as
            defined below) which shall compete with any business conducted by
            the Employer on the date

                                       3
<PAGE>
            hereof. For purposes of this covenant, the term Service Area means
            Puerto Rico, the USVI, Jamaica, and the Dominican Republic. Employee
            acknowledges that he fully understands the scope and meaning of this
            non-compete provision and agrees that it is reasonable in light of
            the circumstances.

      12.   Employee hereby acknowledges and agrees that a violation of Section
            8, 9, 10 or 11 will cause irreparable injury to Employer and
            Employer will be entitled, in addition to any other rights and
            remedies Employer may have at law or in equity, to seek an
            injunction enjoining and restraining Employee from doing or
            continuing to do any such violative act.

      13.   This Agreement and any documents referred to herein shall, in all
            respects, be interpreted, enforced, and governed by and under the
            laws of the State of New Jersey.

      14.   Employee acknowledges that nothing herein shall be interpreted to be
            an admission of liability by Employer.

      15.   Employee agrees that all covenants contained in this Agreement shall
            survive its execution.

      16.   If any provision of this Agreement is deemed to be invalid or
            unenforceable, the remainder of the Agreement shall not be affected,
            and a suitable and equitable provision shall be substituted for the
            invalid and unenforceable provision in order to carry out, as far as
            may be valid and enforceable, the intent and purpose of such invalid
            or unenforceable provision.

      17.   Employee acknowledges and agrees that no promises or representations
            were made to Employee by any person which do not appear written
            herein and that Employee has not relied on any such promise or
            representation. This Agreement contains the entire agreement of the
            parties on the subject matter thereof. This Agreement may not be
            modified except by a writing signed by the parties or as provided in
            paragraph 16. This Agreement may be executed in one or more
            counterparts, each of which will be deemed to be an original copy of
            this Agreement with signatures by fax counting for all purposes as
            original signatures.

      18.   Employee hereby acknowledges that Employee has read and understands
            this Agreement and that Employee signs this Agreement voluntarily,
            with full knowledge of any and all rights which he may have, and
            without coercion and was given the opportunity to review this
            Agreement with his attorney. Employee further acknowledges that the
            waivers Employee has made in this Agreement are knowing, conscious
            and voluntary and are made with full appreciation that Employee is
            forever foreclosed from pursuing any of the claims so waived. After
            having sufficient time to carefully read all the terms and
            conditions of this Agreement, Employee affirms that he completely
            understands the same, as well as

                                       4
<PAGE>
            their consequences. Employee acknowledges that he has been informed
            that he can, and must, seek legal counsel before signing this
            Agreement, and that a reasonable time of at least twenty-one (21)
            days has been given to seek such legal counsel. The parties agree
            that Employee has a period of seven (7) days from the date this
            Agreement is signed to revoke the same. For such reason, the parties
            agree that any payments to be made to Employee hereunder will be
            made after the seven (7) day period has expired.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date set forth below.

                              CONSULTING AGREEMENT

THIS CONSULTING AGREEMENT (this "Agreement") dated April 1, 2002 between
Centennial Communications Corp. (the "Company"), and Carlos Bofill (the
"Consultant").

                                    RECITALS

            A. The Company desires to obtain the consulting services of the
Consultant and the Consultant is willing to provide such services, all upon and
subject to the terms and conditions contained in this Agreement.

            NOW THEREFORE, in consideration of the premises and mutual covenants
set forth in this Agreement, the Company and the Consultant agree as follows:

            1.    Term of Employment.

      The Company hereby employs the Consultant, and the Consultant hereby
accepts employment with the Company, as a consultant, for a period commencing on
the date hereof and ending on the one (1) year anniversary of the date hereof
(April 1, 2003), subject to earlier termination as provided below (the "Term").
In the event that Consultant fails to perform his duties set forth herein after
notice to Consultant of such failure to perform, the Company may terminate this
Agreement upon 15 days prior written notice to Consultant. Upon termination, all
outstanding fees and expenses incurred to the date of termination will be
immediately due and payable. The Company and the Consultant may extend the Term
for additional periods of time upon mutual agreement.

            2.    Duties.

      During the Term, the Consultant will serve as Vice Chairman of Centennial
Caribbean Holding Corp., and will report directly to the Chief Executive Officer
of the Company. During the Term, the Consultant will provide the Company with
such consulting services as are reasonably requested by the Chief Executive
Officer of the Company, including without limitation, assisting with strategic
decisions and opportunities regarding the Company's Caribbean operations and
supporting the Caribbean operations by interfacing with major customers,
strategic partners and government officials in the Caribbean. The Consultant
agrees to perform not less than approximately 40 hours per month towards the
duties described above.

            3.    Compensation and Expenses.

      In exchange for the services to be rendered by the Consultant to the
Company pursuant to this Agreement, during the Term, the Company shall pay the
Consultant compensation at an annual rate of $250,000 per year, payable
semi-monthly in accordance with the Company's typical payroll procedures. In
addition, during the Term, Consultant shall be

                                       7
<PAGE>
eligible to participate in the Company's Cigna health plan in the same manner as
if such Consultant was an employee of the Company and shall receive a housing
allowance in the aggregate amount of $12,000 payable as provided above. The
Company agrees that all reasonable and documented expenses incurred by the
Consultant in the discharge and fulfillment of his duties for the Company will
be reimbursed by the Company upon written substantiation therefor signed by the
Consultant, itemizing such expenses and containing all applicable vouchers or
other substantiation consistent with Company policy in effect from time to time.
Consultant shall submit all requests for expense reimbursement directly to the
Chief Executive Officer.

            4.    Assignability.

      The rights and obligations of the Company under this Agreement shall inure
to the benefit of and be binding upon the successors and assigns of the Company.
Except as otherwise provided herein, the Consultant's rights and obligations
hereunder may not be assigned or alienated and any attempt to do so by the
Consultant will be void.

            5.    Nondisclosure of Confidential Information.

            The Consultant acknowledges that his employment hereunder will
necessarily involve his understanding of and access to certain trade secrets and
confidential information pertaining to the businesses and activities of the
Company. Accordingly, the Consultant agrees that during the period of employment
and at all times thereafter, he will not disclose to any unauthorized third
party any such trade secrets or confidential information and will not (other
than in connection with carrying out his duties) for any reason remove or retain
without the express consent of the Company any figures or calculation, letters,
papers, records or other information of a type likely to be regarded as
confidential. The provisions of this section shall survive the termination, for
any reason, of this Agreement.

            6.    Independent Contractor.

      The Consultant shall be an independent contractor and shall have no power
or authority to bind the Company or to assume or to create any obligation or
responsibility, express or implied, on behalf of or in the name of the Company.
The Company shall not have any liability whatsoever for withholding, collection
or payment of income taxes or for taxes of any other nature on behalf of the
Consultant. It is specifically understood that the Company shall, with respect
to the consulting services to be rendered by the Consultant, not exercise such
control over the Consultant as is contrary to its relationship with the
Consultant as an independent contractor. All references to Consulting Fees to be
paid to the Consultant are to the gross amounts thereof which are due hereunder.
Notwithstanding the provisions of this Section 6, in the event that the
provisions of this Section 6 shall not apply, for whatever reason, then whenever
payments are to be made or income earned by the Consultant, the Company in its
discretion may require the Consultant to remit to the Company, or withhold from
a payment, all or any part of the amount determined in the Company's discretion
to be sufficient to satisfy federal, state and local withholding tax obligations
(including, but not limited to, payment required by the Federal

                                       8
<PAGE>
Insurance Contributions Act and any federal, state, or local income tax
withholding) which the Company or its counsel determines may arise from any
payment to the Consultant pursuant to this Agreement. The Consultant will, at
his own expense, comply with all applicable provisions of the workman's
compensation, unemployment compensation and Social Security laws and/or any
other applicable laws, rules or regulations.

            7.    Miscellaneous.

accordance with the laws of the State of New Jersey, without giving effect to

between the parties with respect to the subject matter of this Agreement.

</TABLE>

            Pursuant to the Centennial Communications Corp. and its Subsidiaries
1999 Stock Option and Restricted Stock Purchase Plan, as amended (the "Plan"),
the Board of Directors of Centennial Communications Corp. (the "Company") has
granted to you on this date an award (the "Award") to purchase, on the terms and
subject to the conditions set forth herein, 50,000 shares of the Company's
Common Stock, $.01 par value ("Common Stock"). Such shares (as the same may be
adjusted as described in Section 10 below) are herein referred to as the
"Restricted Stock." The Award shall constitute and be treated at all times by
you and the Company as restricted stock for federal income tax purposes. The
terms and conditions of the Award are set out below.

            1. Date of Grant. The Award is granted to you on April 1, 2002 (the
"Grant Date"). The Company is issuing and selling the Restricted Stock to you
today in consideration of your agreement to be a consultant of the Company
pursuant to a Consulting Agreement being entered into on the date hereof (the
"Consulting Agreement") and to perform services for the Company in connection
therewith.

            2. Purchase Price.  The purchase price to be paid by you today for
the Restricted Stock is $0.01 per share ($500.00).

            3. Vesting. 20,000 shares of the Restricted Stock will vest on the
Grant Date. The remaining 30,000 shares of Restricted Stock will vest on May 31,
2003, provided that the Consulting Agreement has not been terminated by the
Company prior to February 28, 2003. In the event that the Consulting Agreement
is terminated due to your death or disability, the Award will immediately fully
vest.

            4. Rights as a Stockholder. Subject to the provisions of Section 6
hereof, you will have all rights of a stockholder with respect to all Restricted
Stock being purchased by you today, including the right to vote such Restricted
Stock and to receive any dividends paid thereon.

                                       11
<PAGE>
            5. Investment Representations. You hereby represent and warrant to
the Company that you are acquiring the Restricted Stock for your own account for
investment and not with a view to, or for sale in connection with, any
distribution thereof.

            6. Company's Right of Repurchase upon Termination of Consulting
Agreement

            (a) If the Consulting Agreement terminates for any reason prior to
any vesting date (other than a termination upon your death or disability), then
the Company shall have the right and option, but not the obligation, of
repurchasing all of the unvested Restricted Stock for a consideration equal to
$.01 per Share. The Company may exercise the right and option set forth in this
Section 6(a) by giving you a written notice of election to purchase at any time
within 90 days after the termination of the Consulting Agreement. The closing
for the purchase by the Company of the Restricted Stock pursuant to the
provisions of this Section 6(a) will take place at the offices of the Company on
the date specified in such written notice, which date shall be a business day
not later than 15 days after the date such notice is given. At such closing, you
or your representative will deliver such Restricted Stock, duly endorsed for
transfer, against payment of the purchase price therefore. Such purchase price
shall be payable to you by check payable to your order. To the extent the
Company chooses not to exercise such right and option under this Section 6(a) to
repurchase the Restricted Stock, such Restricted Stock shall thereafter cease to
be subject to the provisions of this Section 6(a).

            (b) In order to facilitate any repurchase of Restricted Stock by the
Company under Section 6(a), the stock certificates representing any part of the
Restricted Stock shall, for so long as such Restricted Stock is subject to
repurchase under such Section 6(a) (including any period during which the
Company has an option to repurchase and any period after the Company gives
notice of its election to repurchase but before the closing of such repurchase
has occurred), remain in the custody of the Company acting as escrow agent and
as custodian for your account. You agree to provide the Company, acting in such
custodial capacity, with a stock power or other instrument of transfer,
appropriately endorsed in blank, in respect of the Restricted Stock.

            7. Acceleration. The Board of Directors of the Company, in its sole
discretion, may at any time accelerate the vesting of the Award.

            8. Transferability of Award. You may not transfer the Restricted
Stock prior to the relevant vesting date.

            9. Representations. (a) You acknowledge receipt of a copy of the
Information Statement Regarding the Plan, prepared and distributed by the
Company pursuant to the Registration Statements on Form S-8 filed by the Company
with the Securities and Exchange Commission on or about December 7, 1999 and
November 28, 2001.

      (b) You further represent and warrant that you understand the federal,
state and local income tax consequences of the granting of the Award to you, the
purchase of the Restricted Stock, and the subsequent sale or other disposition
of any Restricted Stock. In addition, you understand that the Company will be
required to withhold federal, state or local taxes (including

                                       12
<PAGE>
social security and Medicare taxes) in respect of any compensation income
realized by you as a result of the vesting of the Restricted Stock, which
compensation income shall generally equal the excess of the fair market value of
any Restricted Stock received upon vesting over the purchase price of the
Restricted Stock. You are specifically advised to consult immediately with your
tax advisor with respect to the tax consequences of the Award, including without
limitation, the advisability of making an election under Section 83(b) of the
Internal Revenue Code of 1986, as amended. To the extent that the Company is
required to withhold any such taxes, you hereby agree that the Company may
deduct from any payments of any kind otherwise due to you an amount equal to the
total federal, state and local taxes required to be so withheld, or if such
payments are inadequate to satisfy such federal, state and local taxes, or if no
such payments are due or to become due to you, then you agree to provide the
Company with cash funds or make other arrangements satisfactory to the Company
regarding such payment. It is understood that all matters with respect to the
total amount of taxes to be withheld in respect of any such compensation income
shall be determined by the Company in its sole discretion.

            10. Adjustments; Reorganization, Reclassification, Consolidation,
Merger or Sale. (a) In the event that, after the date hereof, the outstanding
shares of Common Stock shall be increased or decreased or changed into or
exchanged for a different number or kind of shares of stock or other securities
of the Company or of another corporation in each such case through
reorganization, merger or consolidation, recapitalization, reclassification,
stock split, split-up, combination or exchange of shares or declaration of any
dividends payable in Common Stock, the Board of Directors of the Company shall,
in good faith, appropriately adjust the number of shares of Common Stock subject
to the Award (to the nearest possible full share), and such adjustment shall be
effective and binding for all purposes of this Agreement and the Plan.

            (b) If any capital reorganization or reclassification of the capital
stock of the Company or any consolidation or merger of the Company with another
corporation, or the sale of all or substantially all its assets to another
corporation, shall be effected after the date hereof in such a way that holders
of Common Stock shall be entitled to receive stock, securities or assets with
respect to or in exchange for Common Stock, then you shall thereafter have the
right to receive upon the basis and upon the terms and conditions specified in
the Award and in lieu of the shares of Common Stock of the Company immediately
theretofore receivable upon the vesting of the Award, such shares of stock,
securities or assets (including cash) as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such stock immediately theretofore so receivable had
such reorganization, reclassification, consolidation, merger or sale not taken
place.

            11. Legend on Stock Certificates. Each stock certificate
representing the unvested portion of the Restricted Stock shall be conspicuously
endorsed with the following legend written on the face thereof:

            THE RIGHTS OF THE HOLDER OF THE SHARES EVIDENCED BY THIS CERTIFICATE
            ARE SUBJECT TO AND LIMITED BY THE TERMS AND CONDITIONS OF A CERTAIN
            RESTRICTED STOCK PURCHASE AGREEMENT DATED APRIL 1, 2002 BETWEEN THE

            AGREEMENT, TO WHICH REFERENCE IS HEREBY MADE, IS ON FILE AND MAY BE
            EXAMINED AT THE OFFICES OF CENTENNIAL COMMUNICATIONS CORP."

            12. Continuation of Consulting Agreement. Neither the Plan nor the
Restricted Stock shall confer upon you any right to continue in the employ of
the Company or any subsidiary or parent thereof, or limit in any respect the
right of the Company or any subsidiary or parent thereof to terminate the
Consulting Agreement or other relationship with the Company or any subsidiary or
parent thereof, as the case may be, at any time.

            13. Plan Documents. This Agreement is qualified in its entirety by
reference to the provisions of the Plan, which are hereby incorporated herein by
reference.

            14. General Provisions. (a) This Agreement shall be governed by and
construed in accordance with the laws of the State of New York. If any one or
more provisions of this Agreement shall be found to be illegal or unenforceable
in any respect, the validity and enforceability of the remaining provisions
hereof shall not in any way be affected or impaired thereby.

            (b) This Agreement and the Plan contain the entire agreement between
the Company and you relating to the Award. Except as expressly provided in this
Agreement or the Plan with respect to certain actions permitted to be taken by
the Board of Directors of the Company or the Committee (as defined in the Plan)
with respect to this Agreement and the terms of the Award, this Agreement may
not be amended, modified, changed or waived other than by written instrument
signed by the parties hereto.

            (c) This Agreement may be executed in two or more counterparts, each
of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.
