union employees of the Company or a Subsidiary and (ii) do not receive grants of
options to purchase Shares under the Company's Long Term Incentive Plan on the

                                       2
<PAGE>

        Section 5.02 Purchase Price. For Optionees who are employees of the
Company or a Subsidiary on the IPO Date, the purchase price per Share under an
Option (the "Purchase Price") shall be not less than the price at which Shares
are offered to the public on the IPO Date (the "IPO Price"). For Optionees who
become employees of the Company or a Subsidiary after the IPO Date, the Purchase
Price shall be the greater of the Fair Market Value of the Shares (as defined
below) on the date of grant or the IPO Price. For purposes of this Program,
"Fair Market Value" shall mean the volume weighted average sale price of the
Shares as reported on Bloomberg on the first day of each month (or the preceding
business day if the first day of the month is not a business day) or, if the
volume weighted average sale price is not available, Fair Market Value shall
mean the fair market value of Shares determined by such methods or procedures as
shall be established from time to time by the Committee.

        Section 5.03 Date of Grant. Optionees who are employed by the Company or
a Subsidiary on the IPO Date will receive a grant of Options under this Program
on the IPO Date. Those employees eligible to be Optionees in the Program under
Section 4.01(b) will be granted Options on the first day of the first month
which is coincident with or follows their date of hire.

        Section 5.04 Term of Option. Options granted under this Program shall
expire on the tenth anniversary of the date of grant (the "Expiration Date").

        Section 5.05 Vesting of the Option. Options granted under this Program
shall vest and be exercisable in accordance with the following schedule: no
Shares subject to the Option will vest until the date which is the first
anniversary of the date of grant; on the first anniversary of the date of grant,
33 1/3% of the Shares subject to the Option will vest; on the second anniversary
of the date of grant, another 33 1/3% of the Shares subject to the Option will
vest; on the third anniversary of the date of grant, the remaining 33 1/3% of
the Shares subject to the Option will vest. Vested Options will be rounded to
the nearest whole number.

        Section 5.06 Manner of Exercise. An Option granted under this Program
may be exercised in whole or in part to the extent it is vested by giving
written notice of exercise in the manner specified by the Committee to the
Company specifying the number of Shares to be purchased. Payment of the purchase
price may be made by one or more of the following methods:

                (i)  In cash, by certified or official bank check or other
        instrument acceptable to the Committee; or

                (ii) By the Optionee delivering to the Company in the manner
        specified by the Committee a properly executed exercise notice together
        with irrevocable instructions to a broker to promptly deliver to the

                                       3
<PAGE>

        Company cash or a check payable and acceptable to the Company to pay the
        purchase price as so provided. The Optionee and the broker shall comply
        with such procedures and enter into such agreements of indemnity and
        other agreements as the Committee shall prescribe as a condition of such
        payment procedure; or

                (iii)  By such other methods as may be permitted by the
        Committee.

Payment instruments will be received subject to collection.  The issue and
allotment of the Shares and the delivery of certificates representing Shares to
be purchased pursuant to the exercise of the Option will be contingent upon
receipt from the Optionee by the Company of the full Purchase Price for such
Shares and any required withholding taxes, and the fulfillment of any other
requirements contained in the Program or applicable provisions of law.

        Section 5.07 Termination of Employment. Subject to the specific
provisions of Article 7 of this Program, if an Optionee ceases to be an employee
of the Company or a Subsidiary, the period within which to exercise the Option
shall be subject to earlier termination as set forth below:

                (i)  Termination Due to Death. If an Optionee ceases to be an
        employee due to his death, the Option held by the Optionee shall become
        fully vested and may be exercised by the Optionee's legally apppointed
        representative for a period of twelve (12) months from the date of death
        or until the Expiration Date, if earlier.

                (ii) Termination Due to Disability. If an Optionee ceases to be
        an employee to due his Disability (as defined herein), the Option held
        by the Optionee shall become fully vested and may be exercised by the
        Optionee (or the Optionee's legally appointed representative if the
        Optionee is incapacitated) for a period of twelve (12) months from the
        date of termination or until the Expiration Date if earlier.

                For purposes of this Program, "Disability" shall mean an
        Optionee's permanent and total incapacity of engaging in any employment
        for his or her employer for physical or mental reasons. Disability shall
        be deemed to exist only when an Optionee meets the requirements for
        disability benefits under his or her employer's long-term disability
        plan or, if the employer has no such plan applicable to an Optionee, the
        requirements for disability benefits under the United States Social
        Security law (or similar law outside the United States) then in effect.

                                       4
<PAGE>

                (iii)  Termination of Employment (other than for "Misconduct" or
        "Change of Control"). If an Optionee ceases to be an employee for any
        reason other than those specified in Section 5.07(i), (ii) and (iv)
        (including voluntary termination and retirement), then any unvested
        portion of the Option shall expire on the date of termination and be of
        no further force and effect and any portion of the Option that is vested
        and by its terms exercisable shall be exercisable by such Optionee for a
        period of three (3) months from the date of termination or until the
        Expiration Date, if earlier.

                (iv) Termination for "Misconduct". If an Optionee ceases to be
        an employee by reason of his or her discharge by his or her employer for
        Misconduct, then any unvested portion of an Option and any vested Option
        that has not been exercised shall be forfeited by Optionee and expire on
        the date of such discharge. The Company shall have the right to delay
        Option exercises for an Optionee who is undergoing an investigation for
        Misconduct that could reasonably lead to his or her discharge for
        Misconduct. For purposes of this Program, "Misconduct" shall mean an
        action or actions, that individually or collectively, are, in the
        opinion of the Committee, which opinion shall be conclusive, willfully
        or wantonly harmful to the Company or a Subsidiary.

                (v)  Termination of Employment due to "Change of Control". If
        the Optionee is terminated by the Company for any reason other than
        Misconduct at any time after a Change of Control, the Option held by the
        Optioneee shall become fully vested and may be exercised for a period of
        twelve (12) months from the date of termination or until the Expiration
        Date, if earlier.

For purposes of this Article 5, transfer of employment from the Company to a
Subsidiary, from a Subsidiary to the Company, or from one Subsidiary to another
shall not be considered a termination of employment.  Nor shall it be considered
a termination of employment if the Optionee is placed on a military or sick
leave or such other leave of absence which is considered by the Committee as
continuing intact the employment relationship; in such a case, the employment
relationship shall be continued until the later of the date when the leave
equals ninety days or the date when an Optionee's right to reemployment shall no
longer be guaranteed either by law or by contract.

        Section 5.08 Rights as a Shareholder. No Optionee shall have any rights
as a shareholder with respect to Shares subject to an Option granted under the
Program until the date of the entry of the name of the Optionee in the register
of members of the Company as the holder of such Shares. No adjustment shall be
made for dividends or other rights for which the record date is prior to the
date of such entry.

                                       5
<PAGE>

        Section 5.09 Transferability. The Option is not transferable otherwise
than by will or by the laws of succession, and shall be exercisable during an
Optionee's lifetime only by the Optionee or, in the case of incapacity, by the
Optionee's legally appointed representative.

                                  ARTICLE 6.
                              Capital Adjustments

        Section 6.01  Capital Adjustments. In the event it is determined that
any dividend or other distribution (whether in the form of cash, Shares, other
securities, or other property), recapitalization, share split, reverse share
split, subdivision, consolidation or reduction of capital, reorganization,
merger, scheme of arrangement, split-up, spin-off or combination involving the
Company or repurchase or exchange of Shares or other rights to purchase Shares
or other securities of the Company, or other similar corporate transaction or
event affects the Shares such that any adjustment is determined by the Committee
to be appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Program, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and type of Shares (or other securities or property) with respect
to which Options may be granted, (ii) the number and type of Shares (or other
securities or property subject to outstanding Options), and (iii) the grant or
exercise price with respect to any Option or, if deemed appropriate, make
provision for a cash payment to the holder of an outstanding Option; provided
that the number of Shares subject to any Option denominated in Shares shall
always be a whole number. Any determination made by either the Committee or the
Board under this Article 6 shall be final, binding and conclusive upon each
Optionee.

                                  ARTICLE 7.
                               Change of Control

        Section 7.01  Treatment of Options Upon a Change of Control. Except as
otherwise determined by the Committee at the time of grant of an Option, in the
event of a Change of Control, each outstanding Option shall be assumed or an
equivalent Option or right shall be substituted by the successor corporation or
a Parent or Subsidiary of the successor corporation. In the event that the
successor corporation refuses to assume or substitute for the Option at the time
of the Change of Control, all Options granted under this Program will become
fully vested and exercisable. If outstanding Options are assumed or substituted
upon a Change of Control and the Optionee is terminated other than for
Misconduct by the successor corporation at any time after a Change of Control,
all Options held by such Optionee shall fully vest and be immediately
exercisable as of the date of such termination. If the Options become fully
vested and exercisable upon a

                                       6
<PAGE>

Change of Control and the Shares of the Company are no longer traded on a
recognized national or international securities market or exchange, Optionees
who hold outstanding Options will be entitled to receive a cash payment equal to
the amount such Optionee would have received had such Optionee exercised and
sold the Shares underlying the Option on the last practicable date prior to the
Change of Control.

        Section 7.02  Definition. For purposes of this Program, a "Change of
Control" shall mean the occurrence of any of the following events:

                (i)  any "person" or "group" (as defined under Sections 13(d)
        and 14(d) of the Securities Exchange Act of 1934 (the "Exchange Act"))
        is or becomes the direct or indirect "beneficial owner" (as defined in
        Rules 13d-3 and 13d-5 under the Exchange Act), of securities
        representing 50% or more of the combined voting power of the Company's
        then outstanding voting securities other than in connection with a
        merger, amalgamation, scheme of arrangement or other combination
        pursuant to which the shareholders of the Company immediately prior to
        such event beneficially own 50% or more of the voting rights exercisable
        generally of any such person which is an entity;

                (ii) such time as the Continuing Directors (as defined below)
        cease for any reason, other than death , incapacity or retirement of a
        Director, to constitute a majority of the Board (or, if applicable, the
        Board of Directors of a successor corporation to the Company), where the
        term "Continuing Director" means at any date a member of the Board who
        (A) was a member of the Board on the IPO Date or (B) was nominated or
        elected subsequent to such date by at least a majority of the Directors
        who were Continuing Directors at the time of such nomination or election
        or whose election to the Board was recommended or endorsed by at least a
        majority of the Directors who were Continuing Directors at the time of
        such nomination or election; provided, however, that there shall be
        excluded from clause (B) any individual whose election to the Board
        occurred as a result of a meeting of the Company requisitioned pursuant
        to Section 74 of the Companies Act 1981 of Bermuda or otherwise as a
        result of action taken by or on behalf of a person other than the Board;

                (iii) any "person" or "group" (other than an employee benefit
        plan or plans maintained by the Company or its Affiliate) comes to
        possess, directly or indirectly, the legal right to direct the
        management and policies of the Company, whether through the ownership of
        securities, by contract or otherwise (other than solely by virtue of
        membership on the Board or any committee thereof); or

                                       7
<PAGE>

                (iv) a merger, amalgamation, scheme of arrangement or other
        combination of the Company with or into another person or any analogous
        or similar transaction or event occurs as a result of which the voting
        rights exercisable at general meetings of the Company in respect of the
        shares of the Company in issue immediately prior to the relevant event
        no longer represent a majority of all the voting rights normally
        exercisable at general meetings of the Company (or, if the Company is
        acquired by another entity in connection with such event, of such
        entity) in respect of the Shares of the Company (or, if the Company is
        acquired by another entity in connection with such event, of the
        securities of such entity) in issue immediately after such event;

        provided, however, that the Offering and any subsequent offering or
series of offerings of the Shares of the Company on an established securities
market or exchange or any distribution of Shares by the Parent, whether by
dividend, spinoff or otherwise, shall not be considered a "Change of Control."

                                  ARTICLE 8.

        Section 8.01  Right of the Company to Terminate Employment Relationship.
Nothing contained in the Program shall confer upon any Optionee any right to be

with the right of his or her employer to terminate such relationship for any
reason whatsoever, with or without cause, at any time.

        Section 8.02  Trading Policy Restrictions. Option exercises (and the

redundancy or resignation; and the benefits granted under the Plan are entirely

Company retains the right to amend or terminate the Plan at any time at its sole
discretion and without notice.

<PAGE>

either case, at such other address as one party may subsequently furnish to the
other party in writing.

        Section 8.05  No Obligation to Exercise. The granting of an Option
hereunder shall impose no obligation upon an Optionee to exercise such Option.

withholding requirements, if any, which the Committee or the Board in its
discretion deems applicable to such exercise.

        Section 8.08  Interpretations and Adjustments. To the extent permitted
by applicable law, an interpretation of the Program and a decision on any matter
within the Committee's or the Board's discretion made in good faith is binding
on all persons.

        Section 8.09  Governing Law. The Program and any and all Options granted
thereunder shall be governed by, and construed and enforced in accordance with,
the laws of Bermuda; except that any references to the laws of the United States
shall be interpreted in accordance with relevant United States law. The
