         5. Termination of Employment.

            (a) During the Employment Term, the Employee's status as an employee
will terminate immediately and automatically and this Agreement shall terminate,
subject to the provisions of Section 2 (b), upon the earliest to occur of:

                   (i)   the death or "Disability" (as defined below) of the
            Employee;

                   (ii)  the discharge of the Employee by the Company "For
            Cause" (as defined below);

                   (iii) termination by Employee "For Good Reason" (as defined
            below); or

                   (iv)  the expiration of the Employment Term.

         The Employee hereby accepts such employment subject to the terms and
conditions hereof.

            (b) As used herein, "For Cause" shall mean any one or more of the
following:

                   (i)   material or repeated violations by the Employee (after
            notice thereof from the Company) of the terms of this Agreement or
            the Employee's material or repeated failure (after notice thereof
            from the Company and the opportunity to remedy the failure within
            thirty (30) days of such notice) to perform the Employee's duties in
            a manner consistent with the Employee's position;

                   (ii)  the Employee's final conviction of a felony; or

                   (iii) substance abuse on the part of the Employee.

         Anything in this Agreement to the contrary notwithstanding, the
Employee's employment may not be terminated "for cause" unless and until there
shall have been delivered to the Employee a copy of a resolution duly adopted by
the affirmative vote of not less than a majority of the entire membership of the
Board (without giving effect to the Employee's status as a director or any vote
of

                                      -2-

<PAGE>

the Employee) at a meeting of the Board called and held for the purpose (after
reasonable notice to the employee and an opportunity for the Employee to be
heard before the Board), finding that in the good faith opinion of the Board the
Employee was guilty of any of the conduct set forth in clause (i) through (ii)
of this subparagraph (b) and specifying the particulars thereof in detail.

         (c) As used herein, "Disability" shall mean a physical or mental
incapacity of the Employee that, in the good faith determination of the Board,
has prevented the Employee from performing the duties assigned the Employee by
the Company for 60 consecutive days or for a period of more than 90 days in the
aggregate in any 12-month period and that, in the determination of the Company
after consultation with a medical doctor appointed by the Company, may be
expected to prevent the Employee for any period of time thereafter from devoting
the Employee's reasonably necessary time and energies (or such lesser time and
energies as may be acceptable to the Company in its sole discretion) to the
Employee's duties as provided hereunder. The Employee's employment hereunder,
except as otherwise agreed to in writing between the Company and the Employee,
shall cease as of the date of such determination. The Employee agrees to submit
to medical examinations, at the Company's sole cost and expense, to determine
whether a Disability exists pursuant to reasonable requests that the Company may
make from time to time. During the period of any such physical or mental
incapacity as provided above, the salary otherwise payable to the Employee may,
in the absolute discretion of the Company, be reduced by the amount of any
disability benefits or payments received by the Employee from the Company or any
disability or health plan funded in whole or in part by the Company (excluding
health insurance benefits or other reimbursement of medical expenses
attributable to insurance policies that have not been funded in any part by the
Company).

         (d) As used herein, "For Good Reason" shall mean breach of any
provision of this Agreement by Company and failure to remedy such breach within
thirty (30) days of written notice; failure of the Employee to be elected to the
Board or to be elected by the Board as its Chairman; the acquisition or a public
announcement that a person or group of persons (other than the holders of the
Company's common stock on the date of this Agreement and other than the Company
or any of its subsidiaries or any employee benefit plan of the Company or any
such subsidiary) has acquired 30% or more of the company's outstanding common
stock; the Company is involved in a merger or other business combination or sale
or transfer of assets or earning power aggregating more than 50% of the assets
or earning power of the Company and its subsidiaries, taken as a whole and as a
result of such transaction the Company's equity holders prior to the transaction
hold less than fifty (50%) percent of the surviving or transferee entity; or
relocation of Employee's place of employment outside the Houston Metropolitan
area.

         6. Effect of Termination on Compensation. In the event of termination
of this Agreement by Employee for Good Reason, or by Company for any reason
other than For Cause, Employee shall be entitled to the following:

         (a) a lump sum payment by Company equal to two hundred (200%) percent
of Employee's annual base salary in effect at the time of termination;

         (b) immediate vesting of any stock options or other equity based awards
issued to Employee prior to termination, with the right to exercise any such
options within five years of termination, but in no event greater than ten years
from date of issuance;

                                      -3-

<PAGE>

         (c) continued participation in any welfare benefit plans including
without limit medical, life insurance and disability insurance for a period of
two (2) years from termination; and

         (d) continued payment of the automobile allowance for a period of two
(2) years from termination.

         (e) a pro rata bonus in an amount determined by calculating the bonus
that the Executive would receive for the Fiscal Year in which the Termination
Date occurs based upon the level of achievement of the applicable performance
goals through the end of the fiscal quarter in which the Termination Date
occurs, annualized as if such level of performance had continued throughout the
entire Fiscal Year and then multiplying such bonus amount by the fraction
obtained by dividing the number of days in the year through the Termination Date
by 365 (the "Pro Rata Bonus");

         (f) Employee shall have no duty to find new employment following the
termination of his employment under circumstances which require Company to pay
any amount to Employee pursuant to this Section 6. Any salary or remuneration
received by Employee from a third party for the providing of personal services
(whether by employment or by functioning as an independent contractor) following
the termination of his employment under circumstances pursuant to which Section
6 applies shall not reduce Company's obligation to make a payment to Employee
(or the amount of such payment) pursuant to the terms of Section 6.

         7. Additional Payments By Company. Notwithstanding anything to the
contrary in this Agreement, in the event that any payment, benefit or
distribution by Company to or for the benefit of the Employee, whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise (a "Payment"), would be subject to the excise tax imposed by
Section 4999 of the Internal Revenue Code of 1986, as amended, or any interest
or penalties with respect to such excise tax (such excise tax, together with any
such interest or penalties, are hereinafter collectively referred to as the
"Excise Tax"), Company shall pay to the Employee an additional payment (a
"Gross-up Payment") in an amount such that after payment by the Employee of all
taxes (including any interest or penalties imposed with respect to such taxes),
including any Excise Tax imposed on any Gross-up Payment, the Employee retains
an amount of the Gross-up Payment equal to the Excise Tax imposed upon the
Payments. Company and the Employee shall make an initial determination as to
whether a Gross-up Payment is required and the amount of any such Gross-up
Payment. The Employee shall notify Company in writing of any claim by the
Internal Revenue Service which, if successful, would require Company to make a
Gross-up Payment (or a Gross-up Payment in excess of that, if any, initially
determined by Company and the Employee) within five days of the receipt of such
claim. Company shall notify the Employee in writing at least ten days prior to
the due date of any response required with respect to such claim if it plans to
contest the claim. If Company decides to contest such claim, the Employee shall
cooperate fully with Company in such action; provided, however, Company shall
bear and pay directly or indirectly all costs and expenses (including additional
interest and penalties) incurred in connection with such action and shall
indemnify and hold the Employee harmless, on an after-tax basis, for any Excise
Tax or income tax, including interest and penalties with respect thereto,
imposed as a result of Company's action. If, as a result of Company's action
with respect to a claim, the Employee receives a refund of any amount

                                      -4-

<PAGE>

paid by Company with respect to such claim, the Employee shall promptly pay such
refund to Company. If Company fails to timely notify the Employee whether it
will contest such claim or Company determines not to contest such claim, then
Company shall immediately pay to the Employee the portion of such claim, if any,
which it has not previously paid to the Employee.

         8. Trade Secrets, Etc. The Employee shall hold, both during the
Employment Term and thereafter, in a fiduciary capacity for the benefit of the
Company all secret or confidential information, knowledge or data relating to
the Company or any of its subsidiaries or corporate affiliates and their
respective businesses and operations, which shall have been obtained by the
Employee during the Employee's employment (whether prior to or after the date
hereof) and which shall not have become public knowledge (other than by acts of
the Employee or his representatives in violation of this Agreement). The
Employee agrees (i) that, without the prior written consent of the Company or as
may be otherwise required by law or legal process, he will not communicate or
divulge any such information, knowledge or data to any party other than the
Company and (ii) to deliver promptly to the Company upon its written request any
confidential information, knowledge or data in his possession, whether produced
by the Company or any of its subsidiaries and corporate affiliates or by the
Employee, that relates to the business of the Company or any of its subsidiaries
and joint ventures or any past, current or prospective activity of the Company
or any of its subsidiaries and joint ventures. The Employee shall be permitted
to retain copies of such data as are necessary in order to enable the Employee
to assert any rights under this Agreement, provided that such data shall be used
solely for such purpose.

         9. Limited Covenant Not to Compete. (a) While Employee is employed by
the Company and for a period of one (1) year following the termination of
Employee's employment with the Company the Employee will not, directly or
indirectly, own, manage, operate, control, be employed by, participate in, or be
connected in any manner with the ownership, management, operation or control of
any company or other business enterprise engaged in a line or lines of business
similar to that of the Company or any of its subsidiaries or joint ventures,
within the State of Texas, Louisiana, Mississippi, Alabama or Florida (including
any area offshore in the Gulf of Mexico or any such state) or any other
jurisdiction, whether within or outside the United States in which the business
of the Company or any of its subsidiaries or joint ventures is carried on, so
long as the Company or any of its subsidiaries or joint ventures carries on a
like line of business therein; provided, however, that nothing contained herein
shall prohibit the Employee from making investments in any company which do not
exceed in the aggregate two percent of the equity interest of such company.

         (b) As part of the consideration for the compensation and benefits to
be paid to the Employee hereunder; to protect the trade secrets and confidential
information of Company and its affiliates that have been and will in the future
be disclosed or entrusted to the Employee, the business good will of the Company
and its affiliates that has been and will in the future be developed in the
Employee, or the business opportunities that have been and will in the future be
disclosed or entrusted to the Employee by the Company and its affiliates; and,
as an additional incentive for the Company to enter in this Agreement, the
Company and the Employee agree to the non-competition obligations hereunder. The
obligations of the Employee set forth in this Section 9 shall apply during the
term of this Agreement and shall survive termination of this Agreement and/or
the termination of the Employee's services under this Agreement regardless of
the reason for such termination.

                                      -5-

<PAGE>

         10. No Tampering. While Employee is employed by the Company and for one
year following the termination of Employee's employment with the Company, the
Employee shall not (a) request, induce or attempt to influence any supplier of
goods or services to the Company curtail or cancel any business they may
transact with the Company; (b) request, induce or attempt to influence any
customers of the Company that have done business with or potential customers
which have been in contact with the Company to curtail or cancel any business
they may transact with the Company; or (c) request, induce or attempt to
influence any employee of the Company to terminate his or her employment with
the Company.

         11. Statements Concerning the Company. The Parties shall refrain, both
during the Employment Term and following the termination of Employee's
employment by the Company for any reason, from publishing any oral or written
statements about the other, any of their affiliates, or any of such entities'
officers, employees, agents or representatives that are slanderous, libelous, or
defamatory; or that disclose private or confidential information about the
Employee or the Company, any of its affiliates, or any of such entities'
business affairs, officers, employees, agents or representatives; or that
constitute an intrusion into the seclusion or private lives of the Employee, the
Company, any of its affiliates, or any of such entities' officers, employees,
agents or representatives or that give rise to unreasonable publicity about the
private lives of the Employee, the Company, any of its affiliates, or any of
such entities' officers, employees, agents or representatives; or that place the
Employee or the Company, any of its affiliates, or any of such entities'
officers, employee, agents or representatives in a false light before the
public; or that constitute a misappropriation of the name or likeness of the
Company, any of its affiliates, or any of such entities; officers, employees,
agents or representatives. A violation or threatened violation of this
prohibition may be enjoined by the courts. The rights afforded the Employee and
the Company and its affiliates under this provision are in addition to any and
all rights and remedies otherwise afforded by law.

         12. Injunctive Relief. In the event of a breach or threatened breach by
the Employee of the provisions of Sections 8, 9, 10 or 11 of this Agreement
during or after the term of this Agreement, the Company shall be entitled to
injunctive relief restraining the Employee from violation of such paragraph.
Nothing herein shall be construed as prohibiting the Company from pursuing any
other remedy at law or in equity it may have in the event of breach or
threatened breach of this Agreement by the Employee.

         13. Binding Effect.

direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the assets or businesses of the Company (i) to assume
unconditionally and expressly this Agreement and (ii) to agree to perform all of
the obligations under this Agreement in the same manner and to the same extent
as would have been required of the Company had no assignment or succession
occurred, such

                                    EXHIBIT A

                     STOCK OPTION AGREEMENT FOR THE GRANT OF
                      NON-QUALIFIED STOCK OPTIONS UNDER THE
                             HORIZON OFFSHORE, INC.
                            2002 STOCK INCENTIVE PLAN

         THIS AGREEMENT is entered into by and between Horizon Offshore, Inc., a
Delaware corporation (the "Company"), and James Devine (the "Optionee").

         WHEREAS, Optionee is an employee to a subsidiary of the Company and the
Company considers it desirable and in its best interest that Optionee be given
an inducement to acquire a proprietary interest in the Company and an incentive
to advance the interests of the Company by possessing an option to purchase
shares of the common stock of the Company, $1.00 par value per share (the
"Common Stock"), in accordance with the Horizon Offshore, Inc. 2002 Stock
Incentive Plan (the "Plan").

         NOW, THEREFORE, in consideration of the premises, it is agreed by and
between the parties as follows:

                                       I.
                                 Grant of Option

         The Company hereby grants to Optionee the right, privilege and option
(the "Option") to purchase 4,611 shares of Common Stock at an exercise price of
$4.98 per share (the "Exercise Price"), effective as of January 1, 2003 (the
"Date of Grant"). The Option shall be exercisable at the time specified in
Section II below. The Option is a non-qualified stock option and shall not be
treated as an incentive stock option under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code").

                                       II.
                                Time of Exercise

         2.1 Subject to the provisions of the Plan and the other provisions of
this Section II, the Optionee shall be entitled to exercise the Option in full
immediately as of the Date of Grant. The Option shall expire and may not be
exercised later than five years following the Date of Grant.

         2.2 During Optionee's lifetime, the Option may be exercised only by him
or his guardian if he has been declared incompetent. In the event of death, the
Option may be exercised as provided herein by the Optionee's estate or by the
person to whom such right devolves as a result of the Optionee's death.

                                      III.
                          Method of Exercise of Option

         3.1 Optionee may exercise all or a portion of the Option by delivering
to the Company a signed written notice of his intention to exercise the Option,
specifying therein the number of shares of Common Stock to be purchased. Upon
receiving such notice, and after the Company has received full payment of the
Exercise Price, multiplied by the number of shares to be received upon exercise
(the "Aggregate Exercise Price"), the appropriate officer of the Company shall
cause the transfer of title of the shares of Common Stock purchased to Optionee
on the Company's stock records and cause to be issued to the Optionee a stock
certificate for the number of shares of Common Stock being acquired. Optionee
shall not have any rights as a stockholder until the stock certificate is issued
to him.

         3.2 The Option may be exercised by the payment of the Aggregate
Exercise Price in cash, in shares of Common Stock held for six months or in a
combination of cash and shares of Common Stock held for six months. The Optionee
may also pay the Aggregate Exercise Price by delivering a properly executed
exercise notice together with irrevocable instructions to a broker approved by
the Compensation Committee (with a copy to the Company) to promptly deliver to
the Company the amount of sale or loan proceeds to pay the Aggregate Exercise
Price.

                                       IV.
                       No Right to Continue as an Employee

         Nothing in this Agreement shall confer upon Optionee any right to
continue to serve as an employee, or shall constitute evidence of any agreement
or understanding, express or implied, that the Company will retain Optionee as
an employee for any period of time, or at any particular rate of compensation.

                                       V.
                                 Binding Effect

         This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, executors, administrators and
successors.

                                       VI.
                               Non-Transferability

         The Option granted hereby may not be transferred, assigned, pledged or
hypothecated in any manner, by operation of law or otherwise, other than by
will, by the laws of descent and distribution or pursuant to a domestic
relations order, as defined in the Code, and shall not be subject to execution,
attachment or similar process.

                                      VII.
                             Inconsistent Provisions

         The Option granted hereby is subject to the provisions of the Plan as
in effect on the date hereof and as it may be amended. In the event any
provision of this Agreement conflicts with such a provision of the Plan, the
Plan provision shall control.

         IN WITNESS WHEREOF the parties hereto have caused this Agreement to be
executed on the Date of Grant.
