the successful conduct and operation of Oceanic's business, to its reputation

                  8.10 Survival and Injunctive Relief. Employee agrees that the
provisions of Section 8 of this Agreement shall survive the termination of this
Agreement, the Employment Period and Employee's employment with Oceanic.
Employee acknowledges that Oceanic has no adequate remedy at law and would be
irreparably harmed if Employee breaches or threatens to breach any of the
provisions of Section 8 of this Agreement, and, therefore, agrees that Oceanic
shall be entitled to injunctive relief to prevent any such breach or threatened
breach thereof and to specific performance of the terms of such sections (in
addition to any other legal or equitable remedy Oceanic may have.)

                  8.11 Restrictions Reasonable. Employee agrees that the
restrictions imposed by Section 8 are reasonable in business scope, geographic
scope and duration. Employee understands that the provisions of Section 8 may
affect or limit Employee's ability to earn a livelihood in a business similar to
the business of Division but Employee agrees that Employee shall receive (or
shall have received) sufficient consideration, remuneration and other benefits
from Oceanic to make enforceable the restrictions and limitations contained in
Section 8 of this Agreement.

         9. Miscellaneous.

                  9.1 Severability. All of the provisions of this Agreement
including without limitation Section 8, are intended by the parties hereto as
separate and divisible provisions and, if, for any reason, any one of them (or
part thereof) is held to be invalid or unenforceable, neither the validity nor
the enforceability of any other provision (or part thereof) shall be affected
thereby. To the extent that any covenant shall be determined to be judicially
unenforceable in any one or more county, or state, or foreign sovereign, that
covenant shall be construed as independent.

                  9.2 Remedies. Each and all of the several rights and remedies
provided for in this Agreement shall be cumulative. No one right or remedy shall
be exclusive of the others or of any right or remedy allowed in law or in
equity. No failure or delay on the part of any party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any
waiver on the part of any party of any right, power or privilege hereunder
preclude any further exercise thereof or the exercise of any other right, power
or privilege. Oceanic shall not be required to give notice to Employee to
enforce strict and full adherence to all terms of this Agreement

                  9.3 Material Conditions/Reasonableness of Agreement. Employee
hereby acknowledges and agrees that the protections set forth in this Agreement
are a material condition to her employment and continued employment with, and
compensation by, Oceanic. Employee hereby acknowledges and agrees that the
obligations which Employee is accepting under this

<PAGE>   8

Agreement are fair, reasonable and valid and understands that the strict and
full compliance with the provisions is a material condition to Employee's
employment with Oceanic.

<PAGE>   9

                  9.4 Survival of Obligations. Employee hereby acknowledges and
agrees that Employee's obligations under this Agreement will continue following
Employee's employment with Oceanic whether or not Employee's employment with
Oceanic is terminated voluntarily or involuntarily or with or without cause.

                  9.5 Judicial Restatement. If for any reason any court of
competent jurisdiction shall find the provisions of Section 8, or any other
section of this Agreement, unreasonable, Employee and Oceanic agree that the
restrictions and limitations contained in Section 8, or any other section of
this Agreement, shall be restated so that they are effective and enforceable to
the fullest extent allowed or allowable under the applicable law of any such
jurisdiction.

                  9.6 Successors. This Agreement is personal to the Employee and
shall not be assignable by the Employee. This Agreement shall be assignable by
Oceanic.

                  9.7 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of California without
reference in the principles of conflict of laws thereunder.

                  9.8 Construction, Amendment, Notice, Taxes. The captions of
this Agreement are not part of the provisions hereof and shall not have any
force or effect. This Agreement may not be amended or modified otherwise than by

            2. Transfers when the Company determines it due to the need in
service. The employee may, after having carried out this type of transfer,

work center due to a promotion for which he has applied, he may not request a
change of position outside of his new work center until twenty-four (24) months
have elapsed from the promotion.

salary corresponding to the new position as soon as he begins to occupy the
same.

e. If his probationary period were not satisfactorily approved, the
employee shall return to his previous position with the salary that would have
corresponded to him if he had continued in the previous position. The Company
shall reinstate to their previous position and salary the employees who would
have been promoted as a result of the vacancies that would have brought about
the promotion of said employee. If, as a result of said promotion, a new
employee had been hired, the Company would be free to separate said new employee
and the Union shall not file any complaint whatsoever under the Complaint and
Grievance Procedure.

f. Except in cases where events occur beyond the control of the Company and/or
the service may be adversely affected, the employee shall be placed in the
position in promotion within a period that shall not exceed thirty (30) days
from the date when the Recruitment Department adjudicates the same to him. g.

level of the new position, or toward another position in which the employee has

days. However, this initial waiting time, of up to a maximum of fifteen (15)

                                    PENSIONS

SECTION 1

         The Company agrees to maintain in effect the Pension Plan known as the
"Puerto Rico Telephone Company Pension Plan for Hourly Employees" put into
effect on January 1st, 1972, and agrees to amend the formula that is utilized to
determine the monthly pension in the following manner:

         o THE YEARS OF SERVICE UP TO 20 YEARS WORKED SHALL BE PAID AT THE RATE
OF $44.00 PER YEAR OF SERVICE.

         o THE PENSION OF THE EMPLOYEE WITH 21 TO 29 YEARS OF SERVICE SHALL BE
CALCULATED AT THE RATE OF $46.00 FOR EACH YEAR OF SERVICE.

         o THE PENSION OF THE EMPLOYEE WITH 30 OR MORE YEARS OF SERVICE SHALL BE
CALCULATED AT THE RATE OF $52.00 FOR EACH YEAR OF SERVICE.

SECTION 2

         To be entitled to a full and normal pension, the regular employee must
have turned 62 years of age and have at

                                       34
<PAGE>   36

least twenty (20) years of credited service. An employee shall be entitled to a
pension without any reduction when he has 30 years of service.

SECTION 3

         To be entitled to early retirement, the regular employee must have
turned 52 years of age with at least twenty (20) years of credited service.

SECTION 4

         To determine the early retirement pension, the same formula for the
determination of the normal pension shall be utilized and from the result three
percent (3%) shall be deducted for each year anticipating his pension at the age
of 62.

SECTION 5

         The Vesting Right section is amended only after having five (5) years
of credited service with the Company. In these cases, the pension will be
calculated on the basis of the formula which is in effect as of the date when
the employee has resigned or has been separated from the Company. The Vesting
Rights are calculated on the basis of the actuarial value at the moment when the
employee is receiving or requests his regular pension upon turning 62 years of
age.

SECTION 6

         An additional benefit is established for the spouses of the employees
in the event of death. This benefit provides in the case of the death of an
employee, before retiring, and that he is eligible as of the date of his death,
to an early retirement pension, a benefit payable to his spouse. The amount of
this benefit to be paid shall be the accrued benefit up to the date of his death
reduced by the corresponding early retirement factor (5% for each year in
advance of his turning 62 years of age if he still does not have 20 years of
credited service, or 3% for each year prior to his turning 62 years of age if he
has 20 or more years of credited service as of the date of his death). In the
cases of the employees who die after having turned 52 years of age and that
these have elected one of the reduced options provided by the plan in the event
of death after retirement, the amount of the benefit shall be reduced on an
actuarial basis basing itself strictly on the option that the employee has
selected.

         The Company and the Union agree that the aforementioned amendments
and/or changes shall be applicable to any employee from the bargaining unit who
retires after the signature of the present Collective Bargaining Agreement.

SECTION 7

         The benefits of the Pension Plan shall be payable in their entirety by
the Company.

SECTION 8

         The employees who choose this benefit, during the effective period of
the Collective Bargaining Agreement, shall receive the following lump sum:

         21 to 29 years of service          9 months of salary
         30 or more years of service       12 months of salary

SECTION 9

         All the employees from the bargaining unit who choose to receive the
retirement benefits after the signature of this Collective Bargaining Agreement,
shall be eligible to participate in a family medical plan which shall be similar
to that one provided to the employees covered by this Collective Bargaining
Agreement, without the benefit of dental coverage.

         The retired employee will have to make the contributions provided in
Article 43 (Medical Plan) during the effective period of this Collective
Bargaining Agreement.

to the fact that the Company has not offered the course or courses required for
his progression or when even though the same has been offered, the Company has
