substantial nature in connection with such Participant's position with the
Company, or other willful act that materially damages the reputation of the

                         [PLATINUM HOLDINGS LETTERHEAD]

___________, 20__

RE: AWARD AGREEMENT FOR RESTRICTED SHARE UNITS

Dear _________________________:

         In recognition of your performance with Platinum Underwriters Holdings,
Ltd. or its subsidiaries (collectively, "Platinum") during 20__, you have been
awarded _____ Restricted Share Units ("RSUs") under Platinum's Annual Incentive
Plan (the "AIP"). The terms of the AIP are incorporated herein by reference,
including the definitions of terms contained in the AIP.

         RSUs are notional units denominated in Common Shares, which represent a
nontransferable, unfunded, unsecured deferred compensation obligation of
Platinum. An RSU will accrue dividends at the same time and in the same amount
as dividends are paid on a Common Share. RSU dividends will be credited to you
as additional RSUs calculated at the price per Common Share on the date the
dividends are paid, rounded up in the nearest whole RSU. Please note, however,
that an RSU may not be sold, assigned, transferred, encumbered, hypothecated or
pledged by you. In addition, RSUs do not have any voting rights.

         On the Exchange Date (as defined below), Holdings will issue to you one
Common Share for each of your RSUs, reduced by an amount in cash equal to your
tax withholding obligation, if applicable; provided, however, that upon a Change
in Control, Platinum will pay you on the date of the Change in Control an amount
in cash equal to the number of your RSUs multiplied by the Fair Market Value of
the Common Shares on the date of such Change in Control, subject to applicable
withholding. If your employment with Platinum terminates prior to the Exchange
Date, however, your RSUs will be forfeited; except in the event that (i) your
employment with Platinum has terminated because of your death or Disability or
(ii) your employment with Platinum has been terminated by you for Good Reason or
by Platinum without Cause. The "Exchange Date" is the earlier of (i) the date
that is 6 months from the date hereof or (ii) the first business day which is 15
days after the date of your death or Disability or termination by you for Good
Reason or by Platinum without Cause, or such other date as may be agreed to by
you (or your beneficiaries) and Platinum.

         This agreement shall be governed by and construed in accordance with
the laws of New York, without regard to choice-of-law rules.
