                             VALIDUS HOLDINGS, LTD.
                              AMENDED AND RESTATED
                           RESTRICTED SHARE AGREEMENT

          THIS AMENDED AND RESTATED AGREEMENT, dated as of February 4, 2006,
between Validus Holdings, Ltd. (the "Company"), a Bermuda corporation, and
George Reeth (the "Employee").

          WHEREAS, the Employee has entered into a written employment agreement
with the Company (the "Employment Agreement") providing for this grant of
Restricted Shares;

          WHEREAS, the Employee has been granted 184,690 Restricted Shares under
the Company's 2005 Long Term Incentive Plan (the "Plan") evidenced by an
agreement between the parties hereto dated as of February 4, 2006, and the
parties hereto wish to amend and restate the terms of such agreement in its
entirety as set forth herein;

          NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein, and for other good and valuable consideration, the parties
hereto agree as follows.

               1. Award of Shares. Pursuant to the provisions of the Plan, the
terms of which are incorporated herein by reference, the Employee is hereby
awarded 184,690 Restricted Shares (the "Award"), subject to the terms and
conditions of the Plan and those herein set forth. The Award is granted as of
February 4, 2006. Capitalized terms used herein and not defined shall have the
meanings set forth in the Plan. In the event of any conflict between this
Agreement and the Plan, the Plan shall control.

               2. Vesting of Award. Subject to the provisions of Section 3 below
and the other terms and conditions of this Agreement, this Award shall become
vested 100% on December 12, 2008, provided, except as set forth in Section 3
below, the Employee remains actively employed by the Company or a Subsidiary
through such vesting date. All dividends and other amounts receivable in
connection with any adjustments to the Shares under Section 4(b) of the Plan
shall be subject to the vesting schedule herein and shall be paid to the
Employee upon any vesting of the Restricted Shares hereunder in respect of which
such dividends or other amounts are payable.

               3. Termination of Employment.

                    (a) Termination Not For Cause or For Good Reason. If the
Employment Period (as defined in the Employment Agreement) shall be terminated
by the Employee for Good Reason (as defined in the Employment Agreement) or by
the Company without Cause (as defined in the Employment Agreement), the Award
shall continue to vest through the Date of Termination (as defined in the
Employment Agreement); provided, however, that in such event no less than 25% of
the Restricted Shares subject to the Award will vest on the

<PAGE>

                                       -2-


Date of Termination. For the avoidance of doubt, except as otherwise set forth
in the immediately preceding sentence, Restricted Shares granted hereunder will
vest only to the extent a vesting date, as set forth above, occurs on or prior
to the Date of Termination. Any portion of the Award that is not vested on the
Date of Termination shall be forfeited by the Employee and become the property
of the Company.

                    (b) Resignation Without Good Reason. If the Employment
Period shall be terminated as a result of the Employee's resignation or leaving
of his employment, other than for Good Reason, no portion of the Award shall
vest on or following the date the Employee provides Notice of Termination (as
defined in the Employment Agreement) without Good Reason to the Company (the
"Notice Date"). Any portion of the Award that has not vested on the Notice Date
shall be forfeited by the Employee and become the property of the Company.

                    (c) Change in Control. Notwithstanding any provision of this
Agreement to the contrary, if, within two years following a Change in Control,
the Employee's employment is terminated by the Company not for Cause or by the
Employee for Good Reason, the Award shall become immediately vested in full upon
such termination of employment. For purposes of this Agreement, "Change in
Control" shall have the meaning set forth in the Plan.

                    (d) Termination of Service; Forfeiture of Unvested Shares.
In the event of Termination of Service of the Employee other than as set forth
above prior to the date the Award otherwise becomes vested, the unvested portion
of the Award shall immediately be forfeited by the Employee and become the
property of the Company.

               4. Certificates. Each certificate or other evidence of ownership
issued in respect of Restricted Shares awarded hereunder shall be deposited with
the Company, or its designee, together with, if requested by the Company, a
stock power executed in blank by the Employee, and shall bear a legend
disclosing the restrictions on transferability imposed on such Restricted Shares
by this Agreement (the "Restrictive Legend"). Upon the vesting of Restricted
Shares pursuant hereto and the satisfaction of any withholding tax liability
pursuant to Section 9 hereof, the certificates evidencing such vested Shares,
not bearing the Restrictive Legend (but still bearing the legend set forth in
Section 11(d) below), shall be delivered to the Employee or other evidence of
vested Shares shall be provided to the Employee.

               5. Rights of a Stockholder. Prior to the time a Restricted Share
is fully vested hereunder, the Employee shall have no right to transfer, pledge,
hypothecate or otherwise encumber such Restricted Share. During such period, the
Employee shall have all other rights of a stockholder, including, but not
limited to, the right to vote and to receive dividends (subject to Section 2
hereof) at the time paid on such Restricted Shares.

               6. No Right to Continued Employment. This Award shall not confer
upon the Employee any right with respect to continuance of employment by the
Company nor shall this Award interfere with the right of the Company to
terminate the Employee's employment at any time.

               7. Transfer of Shares. Any vested Shares delivered hereunder, or
any interest therein, may be sold, assigned, pledged, hypothecated, encumbered,
or transferred or disposed of in any other manner, in whole or in part, only in
compliance with the terms, conditions and restrictions as set forth in the
governing instruments of the Company, the provisions of this Agreement,
applicable federal and state securities laws or any other applicable laws or
regulations and the terms and conditions hereof.

               8. Expenses of Issuance of Shares. The issuance of stock
certificates hereunder shall be without charge to the Employee. The Company
shall pay, and indemnify the Employee from and against any issuance, stamp or
documentary taxes (other than transfer taxes) or charges imposed by any
governmental body, agency or official (other than income taxes) by reason of the
issuance of Shares.

               9. Withholding. No later than the date of vesting of (or the date
of an election by the Employee under Section 83(b) of the Code with respect to)
the Award granted hereunder, the Employee shall pay to the Company or make
arrangements satisfactory to the Committee regarding payment of any federal,
state or local taxes of any kind required by law to be withheld at such time
with respect to such Award and the Company shall, to the extent permitted or
required by law, have the right to deduct from any payment of any kind otherwise
due to the Employee, federal, state and local taxes of any kind required by law
to be withheld at such time.

               10. Market Stand Off Period. The Employee covenants and agrees
that he or she shall not, without the prior written consent of the Company, sell
or otherwise dispose of any shares of stock of the Company during such period (a
"Market Stand Off Period") as the Company or its underwriters shall establish in
connection with the filing of a registration statement in connection with an
initial public offering of the stock of the Company (an "Initial Public
Offering").

               11. Purchase Option. The Employee's Shares are subject to
repurchase as provided below in subsections (a) through (g) below:

                    (a) If the Employee's active service with the Company or a
Subsidiary is terminated by the Employee other than for Good Reason (such
termination of active service shall be treated as occurring on the Notice Date)
or by the Company for Cause, the Company and/or its designee(s) shall have the
option (the "Purchase Option") to purchase, and if the Purchase Option is
exercised, the Grantor (as defined below) shall sell to the Company and/or its
assignee(s), all or any portion (at the Company's option) of the Shares held by
the Grantor (such Shares collectively being referred to as the "Purchasable
Shares").

                    (b) The Company shall give notice in writing to the Grantor
of the exercise of the Purchase Option within one (1) year after the Date of the
Termination (as defined in the Employment Agreement) of the Employee's service.
Such notice shall state the number of Purchasable Shares to be purchased by the
Company and the determination of the purchase price

<PAGE>

                                       -4-


of such Purchasable Shares. If no notice is given within the time limit
specified above, the Purchase Option shall be deemed to have terminated.

                    (c) The purchase price to be paid for the Purchasable Shares
purchased pursuant to the Purchase Option shall be the Book Value (as defined
below) per share as of the date of the notice of exercise of the Purchase Option
times the number of Shares being purchased. The purchase price for the
Purchasable Shares shall be paid in cash or by wire transfer of immediately
available funds. The closing of such purchase shall take place at the Company's
principal executive offices within ten (10) days after the purchase price has
been determined. At such closing, the Grantor shall deliver to the purchaser(s)
the certificates or instruments evidencing the Purchasable Shares being
purchased, duly endorsed (or accompanied by duly executed stock powers) and
otherwise in good form for delivery, against payment of the purchase price by
check of the purchaser(s). In the event that, notwithstanding the foregoing, the
Grantor shall have failed to obtain the release of any pledge or other
encumbrance on any Purchasable Shares by the scheduled closing date, at the
option of the purchaser(s) the closing shall nevertheless occur on such
scheduled closing date, with the cash purchase price being reduced to the extent
of, and paid to the holder of, all unpaid indebtedness for which such
Purchasable Shares are then pledged or encumbered.

                    (d) To ensure the enforceability of the Company's rights
hereunder, each certificate or instrument representing Shares shall bear a
conspicuous legend in substantially the following form:

                    "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                    AN OPTION TO REPURCHASE PROVIDED UNDER THE PROVISIONS OF THE
                    COMPANY'S 2005 LONG TERM INCENTIVE PLAN AND A STOCK OPTION
                    AGREEMENT ENTERED INTO PURSUANT THERETO. A COPY OF SUCH LONG
                    TERM INCENTIVE PLAN AND STOCK OPTION AGREEMENT ARE AVAILABLE
                    UPON WRITTEN REQUEST TO THE COMPANY AT ITS PRINCIPAL
                    EXECUTIVE OFFICES."

                    (e) The Company's rights under this Section 11 shall
terminate upon the consummation of an Initial Public Offering.

                    (f) "Book Value" shall mean the book value of a Share at the
end of the fiscal quarter in which the termination of active service occurs
(which, in the case of termination by the Employee other than for Good Reason,
shall be treated as the Notice Date), as determined on a fully diluted basis by
the Board of Directors in good faith. Such determination shall be final,
conclusive and binding on all persons.

                    (g) "Grantor" shall mean, collectively, the Employee, the
Employee's assignee, the executor or the administrator of the Employee's estate
in the event of the Employee's death, and the Employee's legal representative in
the event of the Employee's incapacity.

               12. Forfeiture Upon Breach of Certain Other Agreements. The
Employee's breach of any noncompete, nondisclosure, nonsolicitation, assignment
of inventions, or other intellectual property agreement that he may be a party
to with the Company or a Subsidiary, in addition to whatever other equitable
relief or monetary damages that the Company or a Subsidiary may be entitled to,
shall result in automatic rescission, forfeiture, cancellation, and return of
any Shares (whether or not otherwise vested) held by the Employees or Grantor,
and all profits, proceeds, gains, or other consideration received through the
sale or other transfer of the or Shares shall be promptly returned and repaid to
the Company.

               13. References. References herein to rights and obligations of
the Employee shall apply, where appropriate, to the Employee's legal
representative or estate without regard to whether specific reference to such
legal representative or estate is contained in a particular provision of this
Agreement.
