conflicts with the interests of the Company or its subsidiaries, (y) interferes
with the proper and efficient performance of his duties for the Company, or (z)

Salary, the size of Employee's family living in Bermuda and foreign exchange
rate fluctuations between the U.S. dollar and Bermuda dollar. The actual amount

          Section 8. TERMINATION OF EMPLOYMENT.

          (a) General. The Term of Employment shall terminate upon the earliest
to occur of (i) Employee's death, (ii) a termination by reason of a Disability,
(iii) a termination by the Company with or without Cause, and (iv) a termination
by Employee with or without Good Reason. Upon any termination of Employee's
employment for any reason, except as may otherwise be requested by the Company
in writing and agreed upon in writing by Employee, Employee shall resign from
any and all directorships, committee memberships or any other positions Employee
holds with the Company or any of its subsidiaries.

          (b) Termination due to Death or Disability. Employee's employment
shall terminate automatically upon his death. The Company may terminate
Employee's employment immediately upon the occurrence of a Disability, such
termination to be effective upon Employee's receipt of written notice of such
termination. In the event Employee's employment is terminated due to his death
or Disability, Employee or his estate or his beneficiaries, as the case may be,
shall be entitled to:

               (i) The Accrued Obligations;

               (ii) Any unpaid Annual Bonus in respect to any completed fiscal
     year which has ended prior to the date of such termination, such amount to
     be paid at the same time it would otherwise be paid to Employee had no such
     termination occurred;

               (iii) A pro rata Annual Bonus (determined using the target Annual
     Bonus if such termination occurs during the fiscal year in which the
     Commencement Date falls, and using the highest Annual Bonus paid or payable
     for the two immediately prior fiscal years for terminations after the
     fiscal year in which the Commencement Date falls) based on the number of
     days elapsed from the commencement of such fiscal year through and
     including the date of such termination, such amount to be paid within five
     (5) business days of such termination; and

               (iv) Vesting, as of the date of such termination, in the number
     of equity-based awards, if any, which would otherwise have vested during
     the one (1) year period immediately following such termination (without
     regard to any subsequent vesting events).

Except as set forth in this Section 8(b), following Employee's termination by
reason of his death or Disability, Employee shall have no further rights to any
compensation or any other benefits under this Agreement.

          (c) Termination by the Company for Cause.

               (i) A termination for Cause shall not take effect unless the
     provisions of this subsection (i) are complied with. Employee shall be
     given not less than fifteen (15) days prior written notice by the Board of
     the intention to terminate his employment for Cause, such notice to state
     in detail the particular act or acts or failure or failures to act that
     constitute the grounds on which the proposed termination for Cause is
     based. Employee shall have fifteen (15) days after the date that such
     written notice has been


                                       -7-

<PAGE>

     given to Employee in which to cure such act or acts or failure or failures
     to act, to the extent such cure is possible. If he fails to cure such act
     or acts or failure or failures to act, the termination shall be effective
     on the date immediately following the expiration of the fifteen (15) day
     notice period. If cure is not possible, the termination shall be effective
     on the date of receipt of such notice by Employee. During any cure period
     provided hereunder, the Board may, in its sole and absolute discretion,
     prohibit Employee from entering the premises of the Company (or any
     subsidiary thereof) or otherwise performing his duties hereunder, and any
     such prohibition shall in no event constitute an event pursuant to which
     Employee may terminate employment with Good Reason; provided, however, that
     if cure is possible, and Employee can reasonably demonstrate to the Board
     that he desires to enter the premises of the Company (or a subsidiary
     thereof) or to otherwise perform his duties hereunder solely to attempt to
     cure the act or acts or failure or failures to act that constitute the
     grounds on which the proposed termination for Cause is based, Employee
     shall be permitted to enter the premises of the Company (or a subsidiary
     thereof) or otherwise to perform his duties hereunder solely for the
     purposes of curing such act or acts or failure or failures to act.

               (ii) In the event the Company terminates Employee's employment
     for Cause, he shall be entitled only to the Accrued Obligations. Following
     such termination of Employee's employment for Cause, except as set forth in
     this Section 8(c)(ii), Employee shall have no further rights to any
     compensation or any other benefits under this Agreement.

          (d) Termination by the Company without Cause. The Company may
terminate Employee's employment at any time without Cause, effective upon
Employee's receipt of written notice of such termination. In the event
Employee's employment is terminated by the Company without Cause (other than due
to death or Disability), Employee shall be entitled to:

               (i) The Accrued Obligations;

               (ii) Any unpaid Annual Bonus in respect to any completed fiscal
     year which has ended prior to the date of such termination, such amount to
     be paid at the same time it would otherwise be paid to Employee had no such
     termination occurred;

               (iii) An amount equal to the Severance Multiplier multiplied by
     the sum of his then current Base Salary and Annual Bonus (determined using
     the target Annual Bonus if such termination occurs during the fiscal year
     in which the Commencement Date falls, and using the highest Annual Bonus
     paid or payable for the two immediately prior fiscal years for terminations
     after the fiscal year in which the Commencement Date falls), payable in
     substantially equal monthly installments over the period commencing on the
     date of termination and ending on the date that is one day prior to two and
     one-half months following the end of the Company's fiscal year in which
     such termination occurs (the "Severance Term");

               (iv) Continuation of participation under the Company's health and
     other insurance plans for a period of years equal to the Severance
     Multiplier, or if such continued participation in is not permissible,
     provide Employee with coverage that is


                                       -8-

<PAGE>

     economically equivalent to Employee through alternative arrangements, or
     the cash value of such coverage, in a manner that places the Employee in a
     net economic position that is at least equivalent to the position in which
     the Employee would have been had such alternative arrangements not been
     used by the Company; and

               (v) Vesting, as of the date of such termination, in the number of
     equity-based awards, if any, which would otherwise have vested during the
     two (2) year period immediately following such termination (without regard
     to any subsequent vesting events).

Notwithstanding the foregoing, the payments and benefits described in
subsections (ii) through (iv) above shall immediately cease, and the Company
shall have no further obligations to Employee with respect thereto, in the event
that Employee breaches any provision of Section 9 hereof.

          Following such termination of Employee's employment by the Company
without Cause, except as set forth in this Section 8(d), Employee shall have no
further rights to any compensation or any other benefits under this Agreement.

          (e) Termination by Employee with Good Reason. Employee may terminate
his employment with Good Reason by providing the Company fifteen (15) days prior
written notice setting forth in reasonable specificity the event that
constitutes Good Reason, which written notice, to be effective, must be provided
to the Company within ninety (90) days of the occurrence of such event. During
such fifteen (15) day notice period, the Company shall have a cure right (if
curable), and if not cured within such period, Employee's termination will be
effective upon the date immediately following the expiration of the fifteen (15)
day notice period, and Employee shall be entitled to the same payments and
benefits as provided in Section 8(d) above for a termination without Cause, it
being agreed that Employee's right to any such payments and benefits shall be
subject to the same terms and conditions as described in Section 8(d) above.
Following such termination of Employee's employment by Employee with Good
Reason, except as set forth in this Section 8(e), Employee shall have no further
rights to any compensation or any other benefits under this Agreement.

          (f) Termination by Employee without Good Reason. Employee may
terminate his employment without Good Reason by providing the Company thirty
(30) days prior written notice of such termination. In the event of a
termination of employment by Employee under this Section 8(f), Employee shall be
entitled only to the Accrued Obligations. In the event of termination of
Employee's employment under this Section 8(f), the Company may, in its sole and
absolute discretion, by written notice accelerate such date of termination and
still have it treated as a termination without Good Reason. Following such
termination of Employee's employment by Employee without Good Reason, except as
set forth in this Section 8(f), and, if applicable, such additional compensation
and benefits described in Section 1(v)(iii), Employee shall have no further
rights to any compensation or any other benefits under this Agreement.

          (g) Release. Notwithstanding any provision herein to the contrary, the
Company may require that, prior to payment of any amount or provision of any
benefit pursuant


                                       -9-

<PAGE>

to subsections (d) or (e) of this Section 8, Employee shall have executed a
general release in favor of the Company and its subsidiaries and related parties
in the form as is reasonably required by the Company, and any waiting periods
contained in such release shall have expired.

          Section 9. RESTRICTIVE COVENANTS.

          Employee acknowledges and agrees that (A) the agreements and covenants
contained in this Section 9 are (i) reasonable and valid in geographical and
temporal scope and in all other respects, and (ii) essential to protect the
value of the Company's business and assets; and (B) by his employment with the
Company, Employee will obtain knowledge, contacts, know-how, training and
experience and there is a substantial probability that such knowledge, contacts,
know-how, training and experience could be used to the substantial advantage of
a competitor of the Company and to the Company's substantial detriment. For
purposes of this Section 9, references to the Company shall be deemed to include
its subsidiaries.

          (a) Confidential Information. At any time during and after the end of
the Term of Employment, without the prior written consent of the Board, except
to the extent required by an order of a court having jurisdiction or under
subpoena from an appropriate government agency, in which event, Employee shall,
to the extent legally permitted, consult with the Board prior to responding to
any such order or subpoena, and except as he in good faith believes necessary or
desirable in the performance of his duties hereunder, Employee shall not
disclose to or use for the benefit of any third party any confidential or
proprietary trade secrets, customer lists, drawings, designs, information
regarding product development (including types of insurance products), marketing
plans, sales plans, management organization information, operating policies
(including underwriting policies and risk assessment policies) or manuals,
business plans, financial records, packaging design or other financial,
commercial, business or technical information (i) relating to the Company, or
(ii) that the Company may receive belonging to suppliers, customers or others
who do business with the Company (including insurance brokers) as a result of
his position with the Company (collectively, "Confidential Information").
Employee's obligation under this Section 9(a) shall not apply to any information
that is publicly available or hereafter becomes publicly available, in each case
without the breach by Employee of this Section 9(a).

          (b) Non-Competition. Employee covenants and agrees that during the
Non-Compete Period, with respect to Bermuda (including any province thereof),
any State of the United States of America or any other jurisdiction in which the
Company engages (or has committed plans to engage) in business during the Term
of Employment, or, following termination of Employee's employment, was engaged
in business (or had committed plans to engage) at the time of such termination
of employment, Employee shall not, directly or indirectly, individually or
jointly, own any interest in, operate, join, control or participate as a
partner, director, principal, officer, or agent of, enter into the employment
of, act as a consultant to, or perform any services for any Person (other than
the Company), that engages in any Competitive Activities. Notwithstanding
anything herein to the contrary, this Section 9(b) shall not prevent Employee
from acquiring as an investment securities representing not more than three
percent (3%) of the outstanding voting securities of any publicly-held
corporation or from being a passive investor in any mutual fund, hedge fund,
private equity fund or similar pooled


                                      -10-
<PAGE>

account so long as Employee's interest therein is less than three percent (3%)
and he has no role in selecting or managing investments thereof.

          (c) Non-Interference. During the Non-Interference Period, Employee
shall not, directly or indirectly, for his own account or for the account of any
other Person, engage in Interfering Activities.

          (d) Return of Documents. In the event of the termination of Employee's
employment for any reason, Employee shall deliver to the Company all of (i) the
property of the Company, and (ii) the documents and data of any nature and in
whatever medium of the Company, and he shall not take with him any such
property, documents or data or any reproduction thereof, or any documents
containing or pertaining to any Confidential Information.

          (e) Works for Hire. Employee agrees that the Company shall own all
right, title and interest throughout the world in and to any and all inventions,
original works of authorship, developments, concepts, know-how, improvements or
trade secrets, whether or not patentable or registerable under copyright or
similar laws, which Employee may solely or jointly conceive or develop or reduce
to practice, or cause to be conceived or developed or reduced to practice during
the Term of Employment, whether or not during regular working hours, provided
they either (i) relate at the time of conception or development to the actual or
demonstrably proposed business or research and development activities of the
Company; (ii) result from or relate to any work performed for the Company; or
(iii) are developed through the use of Confidential Information and/or Company
resources or in consultation with Company personnel (collectively referred to as
"Developments"). Employee hereby assigns all right, title and interest in and to
any and all of these Developments to the Company. Employee agrees to assist the
Company, at the Company's expense (but for no other consideration of any kind),
to further evidence, record and perfect such assignments, and to perfect,
obtain, maintain, enforce and defend any rights specified to be so owned or
assigned. Employee hereby irrevocably designates and appoints the Company and
its agents as attorneys-in-fact to act for and on Employee's behalf to execute
and file any document and to do all other lawfully permitted acts to further the
purposes of the foregoing with the same legal force and effect as if executed by
Employee. In addition, and not in contravention of any of the foregoing,
Employee acknowledges that all original works of authorship which are made by
him (solely or jointly with others) within the scope of employment and which are
protectable by copyright are "works made for hire," as that term is defined in
the United States Copyright Act (17 USC Sec. 101) or any similar Bermuda law or
regulation. To the extent allowed by law, this includes all rights of paternity,
integrity, disclosure and withdrawal and any other rights that may be known as
or referred to as "moral rights." To the extent Employee retains any such moral
rights under applicable law, Employee hereby waives such moral rights and
consents to any action consistent with the terms of this Agreement with respect
to such moral rights, in each case, to the full extent of such applicable law.
Employee will confirm any such waivers and consents from time to time as
requested by the Company.

          (f) Blue Pencil. If any court of competent jurisdiction shall at any
time deem the duration or the geographic scope of any of the provisions of this
Section 9 unenforceable, the other provisions of this Section 9 shall
nevertheless stand and the duration and/or geographic scope set forth herein
shall be deemed to be the longest period and/or greatest size permissible by


                                      -11-

<PAGE>

law under the circumstances, and the parties hereto agree that such court shall
reduce the time period and/or geographic scope to a permissible duration or
size.

          Section 10. BREACH OF RESTRICTIVE COVENANTS.

          Without limiting the remedies available to the Company, Employee
acknowledges that a breach of any of the covenants contained in Section 9 hereof
may result in material irreparable injury to the Company or its subsidiaries for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of such a
breach or threat thereof, the Company shall be entitled to obtain a temporary
restraining order and/or a preliminary or permanent injunction, without the
posting of a bond or the necessity of proving irreparable harm or injury as a
result of such breach or threatened breach of Section 9 hereof, restraining
Employee from engaging in activities prohibited by Section 9 hereof or such
other relief as may be required specifically to enforce any of the covenants in
Section 9 hereof. Notwithstanding any other provision to the contrary, the
Non-Compete Period, in the case of the covenants contained in Section 9(b), and
the Non-Interference Period, in the case of the covenants contained in Section
9(c), shall be tolled during any period of violation of any of such covenants
and during any other period required for litigation during which the Company
seeks to enforce such covenants against Employee or another Person with whom
Employee is affiliated if it is ultimately determined that Employee was in
breach of such covenants.

          Section 11. REPRESENTATIONS AND WARRANTIES OF EMPLOYEE.

          Employee represents and warrants to the Company that:

          (a) Employee's employment will not conflict with or result in his
breach of any agreement to which he is a party or otherwise may be bound;

          (b) Employee has not violated, and in connection with his employment
with the Company will not violate, any non-solicitation, non-competition or
other similar covenant or agreement of a prior employer by which he is or may be
bound; and

          (c) In connection with Employee's employment with the Company, he will
not use any confidential or proprietary information that he may have obtained in
connection with employment with any prior employer.

          Section 12. INDEMNIFICATION.

          Subject to the terms and conditions of the Memorandum of Association
and Bye-Laws of the Company (in each case, as in effect from time to time), the
Company agrees to indemnify and hold Employee harmless to the fullest extent
permitted by the laws of Bermuda, as in effect at the time of the subject act or
omission. In connection therewith, Employee shall be entitled to the protection
of any insurance policies which the Company elects to maintain generally for the
benefit of the Company's directors and officers, against all costs, charges and
expenses whatsoever incurred or sustained by Employee in connection with any
action, suit or proceeding to which he may be made a party by reason of his
being or having been a director,


                                      -12-

<PAGE>

officer or employee of the Company. This provision shall survive any termination
of Employee's employment hereunder.

          Section 13. TAXES.

          The Company may withhold from any payments made under this Agreement
all applicable taxes, including, but not limited to, income, employment and
social insurance taxes, as shall be required by law.

          Section 14. NO MITIGATION OR SET OFF.

          Employee shall not be required to mitigate the amount of any payment
provided for pursuant to this Agreement by seeking other employment or otherwise
and the amount of any payment provided for pursuant to this Agreement shall not
be reduced by any compensation earned as a result of Employee's other employment
or otherwise.

          Section 15. SUCCESSORS AND ASSIGNS; NO THIRD-PARTY BENEFICIARIES.

          (a) The Company. This Agreement shall inure to the benefit of and be
enforceable by, and may be assigned by the Company to, any purchaser of all or
substantially all of the Company's business or assets or any successor to the
Company (whether direct or indirect, by purchase, merger, consolidation or
otherwise). The Company will require, in a writing delivered to Employee, any
such purchaser, successor or assignee to expressly assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform it if no such purchase, succession or assignment had
taken place. The Company may make no other assignment of this Agreement or its
obligations hereunder.

          (b) Employee. Employee's rights and obligations under this Agreement
shall not be transferable by Employee by assignment or otherwise, without the
prior written consent of the Company; provided, however, that if Employee shall
die, all amounts then payable to Employee hereunder shall be paid in accordance
with the terms of this Agreement to Employee's devisee, legatee or other
designee or, if there be no such designee, to Employee's estate.

          (c) No Third-Party Beneficiaries. Except as otherwise set forth in
Section 8(b) or Section 15(b) hereof, nothing expressed or referred to in this
Agreement will be construed to give any Person other than the Company and
Employee any legal or equitable right, remedy or claim under or with respect to
this Agreement or any provision of this Agreement.

          Section 16. WAIVER AND AMENDMENTS.

          Any waiver, alteration, amendment or modification of any of the terms
of this Agreement shall be valid only if made in writing and signed by each of
the parties hereto; provided, however, that any such waiver, alteration,
amendment or modification is consented to on the Company's behalf by the Board.
No waiver by either of the parties hereto of their rights hereunder shall be
deemed to constitute a waiver with respect to any subsequent occurrences or
transactions hereunder unless such waiver specifically states that it is to be
construed as a continuing waiver.

          Section 17. SEVERABILITY.

          If any covenants or such other provisions of this Agreement are found
to be invalid or unenforceable by a final determination of a court of competent
jurisdiction: (a) the remaining terms and provisions hereof shall be unimpaired,
and (b) the invalid or unenforceable term or provision hereof shall be deemed
replaced by a term or provision that is valid and enforceable and that comes
closest to expressing the intention of the invalid or unenforceable term or
provision hereof.

          Section 18. GOVERNING LAW.

          THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO THE CHOICE OF LAW
PRINCIPLES THEREOF) APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED ENTIRELY
WITHIN SUCH STATE.

          Section 19. DISPUTE RESOLUTION.

          Any controversy arising out of or relating to this Agreement or the
breach hereof (other than claims for injunctive relief pursuant to Section 10
hereof) shall be settled by binding arbitration in accordance with the
Employment Dispute Resolution Rules of the American Arbitration Association
(before a single arbitrator) and judgment upon the award rendered may be entered
in any court having jurisdiction thereof. The costs of any such arbitration
proceedings shall be borne equally by the Company and Employee; provided,
however, that the arbitrator shall have the right to award to either party
reasonable attorneys' fees and costs expended in the course of such arbitration
or enforcement of the awarded rendered thereunder. Any award made by such
arbitrator shall be final, binding and conclusive on the parties for all
purposes, and judgment upon the award rendered by the arbitrators may be entered
in any court having jurisdiction thereof.

          Section 20. NOTICES.

          (a) Every notice or other communication relating to this Agreement
shall be in writing, and shall be mailed to or delivered to the party for whom
it is intended at such address as may from time to time be designated by it in a
notice mailed or delivered to the other party as herein provided, provided that,
unless and until some other address be so designated, all notices or
communications by Employee to the Company shall be mailed or delivered to the
Company at its principal executive office, and all notices or communications by
the Company to Employee may be given to Employee personally or may be mailed to
Employee at Employee's last known address, as reflected in the Company's
records.

          (b) Any notice so addressed shall be deemed to be given: (i) if
delivered by hand, on the date of such delivery; (ii) if mailed by courier or by
overnight mail, on the first business day following the date of such mailing;
