                             AMENDMENT NO. 2 TO THE
                            OSI PHARMACEUTICAL, INC.
                    AMENDED AND RESTATED STOCK INCENTIVE PLAN

      Pursuant to the powers reserved to the Board of Directors of OSI
Pharmaceutical, Inc., a Delaware corporation, under Section 13 of the OSI
Pharmaceuticals, Inc., Amended and Restated Stock Incentive Plan (the "Plan"),
the Plan is hereby amended as follows, effective as of June 15, 2005:

                              FIRST AND ONLY CHANGE

      Section 6(f) of the Plan is amended to make the changes indicated and to
read as follows:

            "(f) Effect of Termination of Employment. If a recipient's
      employment (or service as an officer, director or consultant) shall
      terminate for any reason, other than death or Retirement (as defined
      below), the right of the recipient to exercise any option otherwise
      exercisable on the date of such termination shall expire unless such right
      is exercised within a period of 90 days after the date of such
      termination. For Options issued prior to June 15, 2005, the term
      "Retirement" shall mean the voluntary termination of employment (or
      service as an officer, director or consultant) by a recipient who has
      attained the age of 55 and who has completed at least five years of
      service with the Company. For Options issued on or after June 15, 2005,
      unless otherwise determined by the Committee and defined in the applicable
      Award Agreement, the term "Retirement" shall mean the voluntary
      termination of employment (or service as an officer, director or
      consultant) by a recipient who has attained the age of 60 and who has
      completed at least twenty years of service with the Company. If a
      recipient's employment (or service as an officer, director or consultant)
      shall terminate because of death or Retirement, the right of the recipient
      to exercise any option otherwise exercisable on the date of such
      termination shall be unaffected by such termination and shall continue
      until the normal expiration of such option. Notwithstanding the foregoing,
      the tax treatment available pursuant to Section 421 of the Code upon the
      exercise of an Incentive Stock Option will not be available in connection
      with the exercise of any Incentive Stock Option more than three months
      after the date of termination of such option recipient's employment due to
      Retirement. Option rights shall not be affected by any change of
      employment as long as the recipient continues to be employed by either the
      Company or a parent or subsidiary of the Company. In no event, however,
      shall an option be exercisable after the expiration of its original term
      as determined by the Committee. The Committee may, if it determines that
      to do so would be in the Company's best interests, provide in a specific
      case or cases for the exercise of options which would otherwise terminate
      upon termination of employment with the Company for any reason, upon such
      terms and conditions as the
<PAGE>
      Committee determines to be appropriate. Nothing in the Plan or in any
      Award Agreement shall confer any right to continue in the employ of the
      Company or any parent or subsidiary of the Company or interfere in any way
      with the right of the Company or any parent or subsidiary of the Company
      to terminate the employment of a recipient at any time."

Ladies and Gentlemen:

     Goldman, Sachs & Co. (“Goldman Sachs”) and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner
& Smith Incorporated (“Merrill Lynch,” and together with Goldman Sachs, the “Remarketing Agents”)
are undertaking to remarket the 5.25% Senior Guaranteed Notes due November 16, 2007 (the “Notes”)
issued by Platinum Underwriters Finance, Inc., a Delaware corporation (“Platinum Finance”) and
guaranteed by Platinum Underwriters Holdings, Ltd., a Bermuda company (the “Company”) on a senior,
unsecured basis (the “Guarantees”). The Notes (which term as used herein includes the Guarantees
unless the context otherwise requires) were issued pursuant to an Indenture, dated as of October
10, 2002 (the “Base Indenture”), among the Company, Platinum Finance and JPMorgan Chase Bank, N.A.
(as successor to JPMorgan Chase Bank), as Trustee (the “Trustee”), as supplemented by the First
Supplemental Indenture, dated as of November 1, 2002 (the
“First Supplemental Indenture” and,
together with the Base Indenture, the “Indenture”) among the Company, Platinum Finance and the
Trustee, as the same will be supplemented by a Second Supplemental Indenture (the “Second
Supplemental Indenture”) to be entered into among the Company, Platinum Finance and the Trustee, in
relation to the Exchange Securities (as defined in Section 4(d)).

The Notes were initially issued by Platinum Finance as part of an equity security unit (a “Unit”)
issued by the Company that also included a contract (a “Purchase Contract”)

1

 

between the Company and the holder of the Unit. Under each Purchase Contract, the holder of a Unit
is obligated to buy, and the Company is obligated to sell, on November 16, 2005 (the “Share
Purchase Date”), at a price per share equal to the Stated Amount (as defined in the Purchase
Contract Agreement (as defined below)), a number of newly-issued common shares, par value $0.01 per
share, of the Company (the “Common Shares”), equal to the Settlement Rate (as defined in the
Purchase Contract Agreement). The Units are described in and governed by the Purchase Contract
Agreement between the Company and JPMorgan Chase Bank, N.A. (successor to JPMorgan Chase Bank), as
purchase contract agent (the “Purchase Contract Agent”), dated as of November 1, 2002 (the
“Purchase Contract Agreement”).

The Notes constituting a part of the Units have been pledged by the Purchase Contract Agent, on
behalf of the holders of the Units, to U.S. Bank National Association (successor to State Street
Bank and Trust Company), as collateral agent, custodial agent and securities intermediary (the
“Collateral Agent”) pursuant to the Pledge Agreement dated as of November 1, 2002 (the “Pledge
Agreement”) among the Company, the Purchase Contract Agent and the Collateral Agent, to secure the
holders’ obligations to purchase the Common Shares under the Purchase Contracts.

Capitalized terms used and not defined in this Agreement shall have the meanings set forth in the
Purchase Contract Agreement, the Pledge Agreement and the Indenture, as the case may be. Unless the
context otherwise requires, all references to time shall be understood to refer to time in New York
City. As used in this Agreement, “Transaction Documents” means, collectively, the Purchase
Contract Agreement, the Indenture, the Pledge Agreement, this Agreement, the Exchange and
Registration Rights Agreement to be dated as of August 16, 2005 (the “Notes Registration Rights
Agreement”) among the Company, Platinum Finance and the Remarketing Agents, and the Jurisdiction
Agreement, dated as of the date hereof (the “Jurisdiction Agreement”) among Platinum Finance, the
Company, the Remarketing Agents, the Reset Agent and the Purchase Contract Agent.

The Notes of the Units holders and of the Separate Notes holders electing to have their Notes
remarketed will be remarketed by the Remarketing Agents on August 11, 2005 (the “Remarketing
Date”). In the event that the Remarketing Agents cannot remarket the Notes on the Remarketing Date,
the Notes of the Units holders and of the Separate Notes holders electing to have their Notes
remarketed will be remarketed by the Remarketing Agents in a Subsequent Remarketing on each of the
two immediately following Business Days. In the event of a Failed Remarketing with respect to the
first Remarketing Period, the Notes of the Units holders and of the Separate Notes holders electing
to have their Notes remarketed will be remarketed in a Subsequent Remarketing by the Remarketing
Agents on each of the three Business Days immediately preceding October 2, 2005. In the event of a
Failed Remarketing in this second Remarketing Period, the Notes of the Units holders and of the
Separate Notes holders electing to have their Notes remarketed will be remarketed in a Subsequent
Remarketing by the Remarketing Agents on the third Business Day immediately preceding the Share
Purchase Date. In the event of a Last Failed Remarketing, any Units holder that has not otherwise
settled its Purchase

2

 

Contracts in cash by the Business Day immediately preceding the Share Purchase Date will be deemed
to have directed the Company to retain the Notes pledged as collateral in satisfaction of such Unit
holder’s obligations under the related Purchase Contracts.

In the event of a successful remarketing on the Remarketing Date or a Subsequent Remarketing Date,
as the case may be, the applicable interest rate on the Notes will be reset, effective from the
Reset Date, to the Reset Rate which shall be determined by the Reset Agent as the rate that such
Notes should bear in order for the Notes to have a market value at the Remarketing Date or the
Subsequent Remarketing Date, as the case may be, of at least 100.25% of the Remarketing Value,
assuming, for this purpose, even if not true, that all of the Notes are held as components of
Normal Units and will be remarketed, provided that the Reset Rate will in no event exceed the
maximum rate, if any, permitted by applicable law. “Remarketing” means the remarketing of the
Notes on the Remarketing Date or a Subsequent Remarketing Date, as the case may be, pursuant to
this Agreement.

States, the United Kingdom, Bermuda or elsewhere, if the effect of any such event specified in
clause (v) or (vi) in the judgment of the Remarketing Agents makes it impracticable or inadvisable
to proceed with the Remarketing of the Notes on the terms and in the manner contemplated in the

performance by the Company and Platinum Finance of all of their respective obligations hereunder to
be performed at or prior to such Remarketing Closing Date, as to the matters set forth in
subsection (g) of this Section and as to such other matters as the Remarketing Agents may
reasonably request; and

(m) Each of the Company and Platinum Finance shall have entered into the Notes Registration Rights
Agreement.

7. Indemnification.

(a) Each of the Company and Platinum Finance, jointly and severally, will indemnify and hold
harmless each Remarketing Agent and Reset Agent against any losses, claims, damages or liabilities,
joint or several, to which such Remarketing Agent or Reset Agent may become subject, under the Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Offering Circular or the Offering Circular, or any
amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission
to state therein a material fact necessary to make the statements therein not misleading or (ii)
the Remarketing of

22

 

the Notes or the establishment of the Reset Rate, as the case may be, or (iii) the engagement of
the Remarketing Agents or the Reset Agent pursuant to, or the performance by the Remarketing Agents
or Reset Agent of their respective services (including any such services performed on or prior to
the date hereof) contemplated by this Agreement; and will reimburse each Remarketing Agent and
Reset Agent for any legal or other expenses reasonably incurred by such Remarketing Agent or Reset
Agent, as the case may be, in connection with investigating or defending any such action or claim
as such expenses are incurred; provided, however, that neither the Company nor Platinum Finance
shall be liable under clause (a)(i) in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Preliminary Offering Circular or the Offering Circular
or any such amendment or supplement in reliance upon and in conformity with written information
furnished to the Company or Platinum Finance by any Remarketing Agent or Reset Agent, as the case
may be, through Goldman Sachs, expressly for use therein. The Remarketing Agents and Reset Agent
shall incur no liability to and shall be indemnified and held harmless by the Company and Platinum
Finance for, or in respect of, any actions taken, omitted to be taken or suffered to be taken in
the absence of bad faith or gross negligence by the Remarketing Agents or Reset Agent, as the case
may be, in reasonable reliance upon the advice of counsel satisfactory to it or instructions from
the Trustee (pursuant to the Indenture) or the Company or Platinum Finance.

(b) Each Remarketing Agent and Reset Agent, severally and not jointly, will indemnify and hold
harmless the Company and Platinum Finance against any losses, claims, damages or liabilities to
which the Company or Platinum Finance may become subject, under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are
based upon an untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Offering Circular or the Offering Circular, or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein a material fact
necessary to make the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission or alleged omission
was made in the Preliminary Offering Circular or the Offering Circular or any such amendment or
supplement in reliance upon and in conformity with written information furnished to the Company or
Platinum Finance by such Remarketing Agent or Reset Agent, as the case may be, expressly for use
therein; and will reimburse the Company and Platinum Finance for any legal or other expenses
reasonably incurred by the Company or Platinum Finance in connection with investigating or
defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of
the commencement of any action, such indemnified party shall, if a claim in respect thereof is to
be made against the indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the indemnifying party shall not
relieve it from any liability which it may have to any indemnified party, except to the extent it
has been materially prejudiced thereby, and

23

 

in any event it shall not relieve it from any liability otherwise than under subsection (a) or (b)
of this Section 7. In case any such action shall be brought against any indemnified party and it
shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal expenses of other
counsel or any other expenses, in each case subsequently incurred by such indemnified party, in
connection with the defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the written consent of the indemnified party, effect the settlement or
compromise of, or consent to the entry of any judgment with respect to, any pending or threatened
action or claim in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional release of the
indemnified party (or such other release of the indemnified party as shall be satisfactory to the
indemnified party) from all liability arising out of such action or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any
indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold
harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims,
damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying
party shall contribute to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by the Company and Platinum Finance on the
one hand and the Remarketing Agents and Reset Agent on the other from the Remarketing of the Notes.
If, however, the allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required under subsection (c)
above, then each indemnifying party shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only such relative benefits
but also the relative fault of the Company and Platinum Finance on the one hand and the Remarketing
Agents and Reset Agent on the other in connection with the statements or omissions which resulted
in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the Company and Platinum
Finance on the one hand and the Remarketing Agents and Reset Agent on the other hand in connection
with the Remarketing shall be deemed to be in the same proportion as the aggregate principal amount
of the Notes which are, or are to be, remarketed bears to the aggregate fees received by the
Remarketing Agents and Reset Agent with respect to the Remarketing. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission

24

 

to state a material fact relates to information supplied by the Company and Platinum Finance on the
one hand or the Remarketing Agents and Reset Agent on the other and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission.
The Company, Platinum Finance, the Remarketing Agents and Reset Agent agree that it would not be
just and equitable if contributions pursuant to this subsection (d) were determined by pro rata
allocation (even if the Remarketing Agents and Reset Agent were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the equitable
considerations referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this subsection (d), no
Remarketing Agent or Reset Agent shall be required to contribute any amount in excess of the amount
by which its aggregate fee in connection with the Remarketing exceeds the amount of any damages
which such Remarketing Agent or Reset Agent has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. The Remarketing Agents’ and
Reset Agent’s obligations in this subsection (d) to contribute are several and not joint.

(e) The obligations of the Company and Platinum Finance under this Section 7 shall be in addition
to any liability which the Company and Platinum Finance may otherwise have and shall extend, upon
the same terms and conditions, to each director and officer of each Remarketing Agent and Reset
Agent and each person, if any, who controls a Remarketing Agent or Reset Agent within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act, and shall be binding upon or inure to
the benefit of, as the case may be, any successors, assigns, heirs and personal representatives of
the Company, Platinum Finance, the Remarketing Agents and the Reset Agent; and the obligations of
the Remarketing Agents and Reset Agent under this Section 7 shall be in addition to any liability
which the respective Remarketing Agents or Reset Agent, as the case may be, may otherwise have and
shall extend, upon the same terms and conditions, to each officer and director of the Company or
Platinum Finance and to each person, if any, who controls the Company or Platinum Finance within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act and shall be binding upon or
inure to the benefit of, as the case may be, any successors, assigns, heirs and personal
representatives of the Company, Platinum Finance, the Remarketing Agents and Reset Agent.

8. Further Liability. If this Agreement shall be terminated by a Remarketing Agent or Reset Agent
pursuant to Section 10(a), the Company and Platinum Finance shall then be under no liability to
such Remarketing Agent or Reset Agent except as provided in Sections 1, 5 and 7 hereof; but, if for
any other reason, any Notes are not remarketed by or on behalf of the Company and Platinum Finance
as provided herein, the Company and Platinum Finance will reimburse the Remarketing Agents and
Reset Agent, for all out-of-pocket expenses approved in writing by you, including fees and
disbursements of counsel, reasonably incurred by the Remarketing Agents and Reset Agent in making
preparations for the Remarketing of the Notes not so remarketed, but the Company and

25

 

Platinum Finance shall then be under no further liability to the Remarketing Agents and Reset Agent
in respect of the Notes not so remarketed except as provided in Sections 1, 5 and 7 hereof.

9. Dealing in the Notes. Each of the Remarketing Agents and the Reset Agent, when acting
hereunder, or when acting in its individual or any other capacity, may, to the extent permitted by
law, buy, sell, hold or deal in any of the remarketed Notes. Each of the Remarketing Agents and the
Reset Agent may exercise any vote or join in any action which any beneficial owner of remarketed
Notes may be entitled to exercise or take pursuant to the Indenture with like effect as if it did
not act in any capacity hereunder. Each of the Remarketing Agents and the Reset Agent, in its
individual capacity, either as principal or agent, may also engage in or have an interest in any
financial or other transaction with the Company as freely as if it did not act in any capacity
hereunder.

10. Resignation and Removal. (a) The Remarketing Agents and the Reset Agent may resign and be
discharged from their duties and obligations hereunder, and the Company may remove any Remarketing
Agent or Reset Agent, by giving five (5) Business Days’ prior written notice, in the case of a
resignation, to the Company, Platinum Finance and the Purchase Contract Agent and, in the case of a
removal, to the removed Remarketing Agent or Reset Agent; provided that no such resignation nor any
such removal shall become effective until the Company shall have appointed at least one nationally
recognized broker-dealer as successor to such Remarketing Agent or Reset Agent, as the case may be,
and such successor Remarketing Agent or Reset Agent shall have entered into a remarketing agreement
with the Company, Platinum Finance and the Purchase Contract Agent in which it shall have agreed to
conduct the remarketing substantially in accordance with the Transaction Documents. In any such
case, the Company will use its reasonable efforts to appoint a successor Remarketing Agent or Reset
Agent, as the case may be, and enter into such a remarketing agreement with such person as soon as
reasonably practicable.

(b) The provisions of this Section 10 shall survive the resignation or removal of any Remarketing
Agent or Reset Agent pursuant to this Agreement.

11. Termination of Remarketing Agreement. This Agreement shall terminate as to any Remarketing
Agent or Reset Agent, which is replaced on the effective date of the resignation or removal of such
Remarketing Agent or Reset Agent pursuant to Section 10. In addition, the obligations of such
Remarketing Agent or Reset Agent may be terminated by it by notice given to the Company and
Platinum Finance prior to 10:00 a.m., New York City time, on the Remarketing Date or a Subsequent
Remarketing Date, as the case may be, if, prior to that time, any of the conditions precedent to
the obligations of the Remarketing Agents and the Reset Agent described in Section 6 hereof shall
have failed to occur or upon the occurrence of any of the events in Section 6(g), (h) or (i), which
termination shall be without liability on the part of any party to any other party, except that
Sections 1, 5, 7, 8 and 10 shall at all times be effective and shall survive such termination.

26

 

12. Survival. Notwithstanding any termination pursuant to Section 10 or 11 hereof, the obligations
set forth in Section 5 hereof shall survive and remain in full force and effect until all amounts
payable under Section 5 shall have been paid in full. In addition, each former Remarketing Agent
and Reset Agent shall be entitled to the rights and benefits under Sections 1 and 7 of this
Agreement notwithstanding the replacement of such Remarketing Agent or Reset Agent. The respective
indemnities, agreements, representations, warranties and other statements of the Company, Platinum
Finance, the Remarketing Agents or Reset Agent, as set forth in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof) made by or on behalf
of any Remarketing Agent or Reset Agent, or any controlling person of any Remarketing Agent, Reset
Agent, Platinum Finance or the Company, or any officer or director or controlling person of the
Company or Platinum Finance, and shall survive the Remarketing.

13. Remarketing Agents’ and Reset Agent’s Performance; Duty of Care.

(a) The duties and obligations of the Remarketing Agents and the Reset Agent shall be determined
solely by the express provisions of this Agreement. No implied covenants or obligations of or
against the Remarketing Agents or the Reset Agent shall be read into this Agreement. In the absence
of bad faith on the part of a Remarketing Agent or Reset Agent, as the case may be, such
Remarketing Agent or Reset Agent may conclusively rely upon any document furnished to it which
purports to conform to the requirements of, or any information supplied to it by the Company or
Platinum Finance pursuant to, the Transaction Documents or the Notes as to the truth of the
statements expressed in any such documents. Each of the Remarketing Agents and the Reset Agent
shall be protected in acting upon any document or communication reasonably believed by it to be
signed, presented or made by the proper party or parties. In no event shall the Remarketing Agents
or the Reset Agent be liable to any person for special, indirect or consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the Remarketing Agents or
Reset Agent, as the case may be, have been advised of the likelihood of such loss or damage and
regardless of the form of action.

(b) Neither the Remarketing Agents nor the Reset Agent shall have any obligation to determine
whether there is any limitation under applicable law on the Reset Rate on the Notes or, if there is
any such limitation, the maximum permissible Reset Rate on the Notes, and they shall rely solely
upon written notice from the Company (which the Company agrees to provide on or prior to the
Business Day immediately preceding the Remarketing Date or a Subsequent Remarketing Date, as the
case may be) as to whether or not there is any such limitation and, if so, the maximum permissible
Reset Rate. The Reset Agent shall not be liable for any error resulting from the use of or reliance
on a source of information in good faith to make any determination, calculation or declaration
hereunder. In acting under this Agreement and in connection with the Notes, the Remarketing Agents
and the Reset Agent are acting solely as agents of the Company and Platinum Finance, do not assume
any obligations to, or relationship of agency or trust for or with, any of the owners or holders of
the Notes and none of the Remarketing Agents or

27

 

the Reset Agent, acting under this Agreement, shall incur any liability (whether direct or
indirect, in contract or tort or otherwise) to the Company or Platinum Finance or their respective
security holders or creditors or to any beneficial owner or holder of remarketed Notes in its
individual capacity or as Remarketing Agent or Reset Agent, as the case may be, relating to or
arising out of the engagement of such Remarketing Agent or Reset Agent pursuant to, or the
performance by such Remarketing Agent or Reset Agent of their respective services contemplated by,
this Agreement or for any action or failure to act in connection with the Remarketing or otherwise,
except to the extent such liability is found in a final judgment by a court of competent
jurisdiction to have resulted from the bad faith or gross negligence on the part of such
Remarketing Agent or Reset Agent, as the case may be. The Remarketing Agents and Reset Agent may,
upon obtaining the prior written consent of the Company and Platinum Finance, perform any duties
hereunder through agents or attorneys, and the Remarketing Agent and Reset Agent shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed with
due care and in the absence of bad faith or gross negligence by it hereunder. Each of the
Remarketing Agents and Reset Agent may, but shall not be obligated to, purchase remarketed Notes
for its own account. Any determination made by the Remarketing Agents or the Reset Agent in
accordance with the terms of this Agreement and the Notes and in the absence of bad faith or gross
negligence shall be conclusive and binding upon the Remarketing Agents, the Reset Agent, the
Company, Platinum Finance, the Trustee and the owners of the Notes, absent manifest error. The
provisions of this Section 13 shall survive any termination of this Agreement and shall also
continue to apply to every Remarketing Agent and Reset Agent notwithstanding their resignation or
removal.

14. Miscellaneous.

(a) Except as otherwise stated herein, all statements, requests, notices and agreements hereunder
shall be in writing, and if to the Remarketing Agents, shall be delivered or sent by mail or

and 13 hereof, the officers and directors of the Company and Platinum Finance and each person who
controls the Company or Platinum Finance or the Remarketing Agents or Reset Agent, and their
respective heirs, executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Notes
from the Remarketing Agents shall be deemed a successor or assign by reason merely of such
purchase.

(c) Time shall be of the essence of this Agreement.

(d) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF

EXHIBIT A

FORM OF OPINION OF DEWEY BALLANTINE LLP DELIVERED PURSUANT TO SECTION 6(b)

     (i) Assuming each of the Remarketing Agreement, the Jurisdiction Agreement,
the Notes Registration Rights Agreement and the Indenture has been duly authorized,
executed and delivered by the Company under Bermuda law, each of the Remarketing Agreement,
the Jurisdiction Agreement, the Notes Registration Rights Agreement and the Indenture has
been duly delivered by the Company under New York law, and each of the Notes Registration
Rights Agreement (when executed and delivered by the Remarketing Agents, and assuming it is
binding on the Remarketing Agents) and the Indenture (assuming it is binding on the
Trustee), constitutes a valid and legally binding obligation of the Company, enforceable
against the Company in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors’ rights and to general equity principles (other than the
indemnities provided for in the Notes Registration Rights Agreement, as to which no opinion
need be expressed).

     (ii) Each of the Indenture, the Remarketing Agreement, the Notes
Registration Rights Agreement and the Jurisdiction Agreement has been duly authorized,
executed and delivered by Platinum Finance, and each of the Notes Registration Rights
Agreement (when executed and delivered by the Remarketing Agents, and assuming it is
binding on the Remarketing Agents) and the Indenture, constitutes a valid and legally
binding obligation of Platinum Finance, enforceable against Platinum Finance in accordance
with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting creditors’
rights and to general equity principles (other than the indemnities provided for in the
Notes Registration Rights Agreement, as to which no opinion need be expressed), and the
Indenture has been duly qualified under the Trust Indenture Act.

     (iii) The Notes have been duly authorized, issued and executed by Platinum
Finance, and, when authenticated by the Trustee in accordance with the Indenture and
delivered to the Remarketing Agents against payment therefor in accordance with the terms
of the Remarketing Agreement, the Notes will have been duly delivered by Platinum Finance,
will be in the form contemplated by the Indenture, will be entitled to the benefits of the
Indenture and will constitute valid and legally binding obligations of Platinum Finance
enforceable against Platinum Finance in accordance with their terms, subject to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors’ rights and to general equity principles,
and will conform in all material respects to the description thereof in the Offering
Circular under the caption “Description of the Remarketed Notes.”

34

 

     (iv) The Exchange Securities have been duly authorized by Platinum Finance,
and, when authenticated by the Trustee in accordance with the Indenture and the Second
Supplemental Indenture and delivered in accordance with the Notes Registration Rights
Agreement, the Exchange Securities will have been duly delivered by Platinum Finance, will
be in the form contemplated by the Indenture and the Second Supplemental Indenture, will be
entitled to the benefits of the Indenture and the Second Supplemental Indenture, will
constitute valid and binding obligations of Platinum Finance enforceable against Platinum
Finance in accordance with their terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors’ rights and to general equity principles, and will conform in all
material respects to the description thereof in the Offering Circular under the caption
“Description of the Remarketed Notes.”

     (v) Assuming the Guarantees endorsed on the Notes have been duly authorized
by the Company under Bermuda law and assuming the payment therefor in accordance with the
terms of the Remarketing Agreement, the Guarantees constitute valid and binding obligations
of the Company, enforceable against the Company in accordance with their terms, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization and similar laws of general
applicability relating to or affecting creditors’ rights and to general equity principles,
and are in the form contemplated by, and entitled to the benefits of, the Indenture.

     (vi) It is not necessary in connection with Remarketing of the Notes by the
Remarketing Agents pursuant to the Remarketing Agreement and the Offering Circular to
register under the Act such Notes.

     (vii) Based solely on such counsel’s review of the Certificate of Good
Standing of Platinum US certified by the Secretary of State of the State of Maryland, dated
such date as stated in such counsel’s opinion (with a telephonic confirmation dated the
date of such counsel’s opinion), Platinum US has been duly incorporated and is an existing
corporation in good standing under the laws of the State of Maryland, with corporate power

     (x) Assuming that each of the Filed Agreements that is governed by New York

the Company under Bermuda law and is binding on the other party or parties thereto, each of
such agreements has been duly delivered by the Company under New York law and constitutes a
valid and legally binding obligation of the Company, enforceable against the Company in
accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to or
affecting creditors’ rights and to general equity principles (other than the indemnities

opinion is expressed).

     (xi) Assuming that each of the Filed Agreements that is governed by New York
law and to which Platinum US is a party has been duly authorized, executed and delivered by

Platinum Finance and constitutes a valid and legally binding obligation of Platinum Finance
enforceable against Platinum Finance in accordance with its terms, subject to bankruptcy,
insolvency, fraudulent transfer, reorganization and similar laws of general applicability
relating to or affecting creditors’ rights and to general equity principles, except that
such counsel need not express any opinion as to the enforceability of any leases,
sub-leases or assignments of leases or other agreements relating to real property
constituting a Filed Agreement or as to the enforceability of the indemnities provided for
in the 2005 Registration Rights Agreement.

36

 

     (xiii) No consent, approval, authorization or order of, or qualification
with, any United States Federal or New York State governmental body or agency is required
for the Remarketing of the Notes, the issuance and delivery of the Exchange Securities or
the consummation by the Company and Platinum Finance of the transactions contemplated by
the Remarketing Agreement, the Jurisdiction Agreement, the Notes Registration Rights
Agreement or the Indenture, except (A) such as may be required by the securities or Blue

Exchange Securities pursuant to and in the manner contemplated by the Remarketing Agreement
and the Notes Registration Rights Agreement and the performance by the Company and Platinum

Agreement, the Notes Registration Rights Agreement and the Indenture will not (i) result in
a default under or a breach of any of the Filed Agreements that is governed by New York law
and to which the Company or any subsidiary is a party, except any such default or breaches
as (A) would not individually or in the aggregate have a material adverse effect on the
consolidated financial position, shareholders’ equity or results of operations of the
Company and its subsidiaries, taken as a whole, (B) would not affect the due authorization
and enforceability in accordance with their terms of the Notes or the Exchange Securities;
or (C) would not adversely affect the consummation of the transactions contemplated by the
Remarketing Agreement, the Notes Registration Rights Agreement and the Indenture, or (ii)
violate any Federal law of the United States or law of the State of New York applicable to
the Company or Platinum Finance; provided, however, that for purposes of this paragraph
(xiv), such counsel need not express any opinion with respect to Federal or state
securities laws, other antifraud laws or fraudulent transfer laws; and provided, further,
that insofar as performance by the Company and Platinum Finance of their respective
obligations under such agreements is concerned, such counsel need not express any opinion
as to bankruptcy, insolvency, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors’ rights or general equity principles.

     (xv) Assuming that the Jurisdiction Agreement has been duly authorized,
executed and delivered by the Company under Bermuda law and is binding on the other party
or parties thereto and assuming that the Jurisdiction Agreement is not terminated, amended
or modified in any way, under the laws of the State of New York relating to submission to
jurisdiction, pursuant to the Jurisdiction Agreement, (A) each of the Company and Platinum
Finance has validly and irrevocably submitted to the non-exclusive jurisdiction of any New
York Court with respect to any legal suit, action or proceeding against the

37

 

Company or Platinum Finance brought by any Remarketing Agent, Reset Agent, Purchase
Contract Agent or Control Person (as defined in the Jurisdiction Agreement) arising out of
or based on the Remarketing Agreement, the Notes Registration Rights Agreement or the
transactions contemplated thereby, and has validly and irrevocably waived, to the fullest
extent that it may effectively do so, any objection to the venue of such suit, action or
proceeding in any such court, and (B) each of the Company and Platinum Finance has validly
appointed CT Corporation System as its authorized agent for the purpose and to the extent
described in the Jurisdiction Agreement, and service of process effected on such agent in
the manner set forth therein will be effective to confer valid personal jurisdiction over
the Company and Platinum Finance with respect to such suit, action or proceeding, assuming,
in each of clauses (A) and (B), (1) the validity of such actions under Bermuda law and (2)
the due authorization, execution and delivery of the Jurisdiction Agreement by the
Remarketing Agents.

     (xvi) Neither the Company nor Platinum Finance is required to register as an
“investment company” under the Investment Company Act and the rules and regulations
promulgated thereunder.

     (xvii) The statements set forth in the Form 10-K under the caption “Related
Party Transactions,” and in the Offering Circular under the captions “Description of the

Consequences to U.S. Holders,” “Material U.S. Federal Income Tax Considerations—U.S.
Federal Income Tax Consequences to Non-U.S. Holders,” “ERISA Considerations,” and
“Remarketing” insofar as they purport to describe the provisions of the New York and
Federal laws and documents referred to therein, are true and complete in all material
respects.

     Such counsel shall also furnish to you a written statement that each of the documents
incorporated by reference in the Offering Circular which were filed under the Exchange Act,
as of their respective dates (in each case, other than the financial statements and related
notes and schedules and other financial information therein, as to which such counsel need
express no opinion), appeared on their face to be appropriately responsive in all material
respects to the requirements of the Exchange Act and the applicable rules and regulations
of the Commission thereunder. Further, nothing came to such counsel’s attention in the
course of its review that has caused such counsel to believe that the Offering Circular, as
of its date, and the documents incorporated therein by reference which were filed under the
Exchange Act, as of their respective dates (in each case, other than the financial
statements and related notes and schedules and other financial information therein, as to
which such counsel need express no opinion) contained any untrue statement of a material
fact or omitted to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not misleading.
Also, nothing has come to such counsel’s attention that has caused such counsel to believe
that, as

38

 

of the date and time of delivery of such counsel’s written opinion, the Offering
Circular (other than the financial statements and related notes and schedules and other
financial information therein, as to which such counsel need express no opinion), contained
any untrue statement of a material fact or omitted to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under which they
were made, not misleading. Such counsel shall state that they do not assume any
responsibility for the accuracy or completeness of the statements contained in the Offering
Circular, or in any of the documents incorporated by reference in the Offering Circular or
in any further amendment or supplement thereto which were filed under the Exchange Act,
except for those made under the caption “Related Party Transactions” in the Form 10-K and
under the captions “Description of the Remarketed Notes,” “Material U.S. Federal Income Tax
Considerations—U.S. Federal Income Tax Consequences to U.S. Holders,” “Material U.S.
Federal Income Tax Considerations—U.S. Federal Income Tax Consequences to Non-U.S.
Holders,” “ERISA Considerations” and “Remarketing” in the Offering Circular insofar as they
relate to provisions of documents or of United States Federal tax law therein described.

Such counsel may state that its opinions are solely for the benefit of the Remarketing Agents and
may not be relied upon by any other person.

EXHIBIT B

FORM OF OPINION OF CONYERS DELIVERED PURSUANT TO SECTION 6(c)

     (i) Each of the Company and Platinum Bermuda is a limited liability company duly
incorporated and existing under the laws of Bermuda in good standing (“good standing” meaning
solely that it has not failed to make any filing with any Bermuda governmental authority or to pay
any Bermuda government fee or tax which would make it liable to be struck off the Register of
Companies and thereby cease to exist under the laws of Bermuda).

     (ii) Each of the Company and Platinum Bermuda has the necessary power and authority
to own, lease and operate its properties as described in the Offering Circular.

     (iii) The Company has the necessary corporate power and authority to carry on its
business as described in the Offering Circular. No further approvals of the insurance regulatory,
governmental or administrative body or authority of Bermuda are required for the conduct of such
business by the Company.

     (iv) Platinum Bermuda has the necessary corporate power and authority to carry on
its business as described in the Offering Circular, including its insurance and reinsurance
business as described in the Offering Circular, and is registered as a Class 4 insurer under the
Insurance Act 1978 effective June 6, 2002 and is licensed to carry on long-term business subject to
the provisions of the Insurance Act 1978 and the regulations promulgated thereunder, and the
conditions set out in Schedule I to the Certificate of Registration, issued by the Bermuda Monetary
Authority to Platinum Bermuda, dated June 6, 2002. No further approvals of the insurance
regulatory, governmental or administrative body or authority of Bermuda are required for the
conduct of such business by Platinum Bermuda.

     (v) The Company has the necessary corporate power and authority to enter into and
perform its obligations under each of the Transaction Documents. The execution and delivery of
each of the Transaction Documents, by the Company and the performance by the Company of its
obligations thereunder will not violate the memorandum of association or bye-laws of the Company
nor any applicable law, regulation, order or decree in Bermuda.

     (vi) The Company has taken all corporate action required to authorize its execution,
delivery and performance of each of the Transaction Documents. Each of the Transaction Documents
has been duly executed and delivered by or on behalf of the Company and constitutes the valid,
binding and enforceable obligation of the Company in accordance with the terms thereof.

     (vii) The Company has taken all corporate action required to authorize its
execution, delivery and performance of the Guarantees endorsed on the Notes. The Guarantees
endorsed on the Notes have been duly executed and delivered by or on behalf

40

 

of the Company and constitute the valid and binding obligation of the Company, enforceable in
accordance with the terms thereof.

     (viii) No order, consent, approval, license, authorization or validation of,
registration with or exemption by any government or public body or authority of Bermuda or any
sub-division thereof is required to authorize or is required in connection with the execution,
delivery, performance and enforcement of each of the Transaction Documents, except such as have
been duly obtained in accordance with Bermuda law.

     (ix) It is not necessary or desirable to ensure the enforceability in Bermuda of
each of the Transaction Documents that they be registered in any register kept by, or filed with,
any governmental authority or regulatory body in Bermuda.

     (x) Based solely on a review of a certified copy of the Company’s Memorandum of
Association, the Company has an authorized share capitalization as described in the Offering
Circular. Based solely on a review of a certified copy of the Register of Members of the Company
prepared by the branch registrar of the Company (the “Register of Members”), dated such date as
stated in such counsel’s opinion, the issued share capital of the Company at the date of the
Register of Members consists of such number of common shares, as specified in such counsel’s
opinion and such shares are duly authorized and validly issued, fully paid and nonassessable (which
term means when used in this Section 7(c) that no further sums are required to be paid by the
holders thereof in connection with the issue thereof).

     (xi) Subject to the requirement that any shares of the Company are listed on the
Exchange or on another appointed stock exchange (as defined in section 2(1) of the Companies Act
1981), the Company has received permission under the Exchange Control Act 1972 (and Regulations
made thereunder) from the Bermuda Monetary Authority for: (i) the issue and subsequent free
transferability of the Company’s shares, up to the amount of its authorized capital from time to
time, to and among persons non resident of Bermuda for exchange control purposes; (ii) the issue
and subsequent free transferability of up to 20% of the Company’s shares in issue from time to time
to persons resident in Bermuda for exchange control purposes; and (iii) the issuance of options,
warrants, depository receipts, rights, loan notes and other securities of the Company and the
subsequent free transferability thereof.

     (xii) The Guarantees conform, as to legal matters, to the description thereof
contained in the Offering Circular in all material respects.

     (xiii) The Guarantees will not constitute unlawful financial assistance by the
Company under Bermuda law.

     (xiv) Based solely on such counsel’s review of a certified copy of the Register of
Members of Platinum Bermuda dated as of the date set forth in such opinion, all of the issued
shares of Platinum Bermuda have been duly authorized and validly issued, fully

41

 

paid and non-assessable (as such term is defined above) and are registered in the name of the
Company.

     (xv) None of this Agreement, the Jurisdiction Agreement and the Notes Registration
Rights Agreement will be subject to ad valorem stamp duty in Bermuda and no registration,
documentary, recording, transfer or other similar tax, fee or charge is payable in Bermuda in
connection with the execution, delivery, filing, registration or performance of this Agreement, the
Jurisdiction Agreement or the Notes Registration Rights Agreement.

     (xvi) Under current Bermuda law there is no Bermuda income tax, withholding tax,
capital gains tax, capital transfer tax, estate or inheritance tax, payable by investors who are
not resident in Bermuda (or are deemed not to be resident in Bermuda for Bermuda exchange
purposes).

     (xvii) The Company and Platinum Bermuda have received from the Bermuda Minister of
Finance an assurance under The Exempted Undertakings Tax Protection Act 1966 of Bermuda to the
effect that in the event Bermuda enacts any legislation imposing tax computed on profits or income,
or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or
inheritance tax, then such tax will not apply to the Company and Platinum Bermuda or to any of
their operations or their shares, debentures or other obligations, until March 28, 2016. This
assurance does not preclude the application of any tax or duty to persons that are “ordinarily
resident” in Bermuda (the Company and Platinum Bermuda are not “ordinarily resident” in Bermuda) or
the application of any tax payable by the Company or Platinum Bermuda in respect of real property
owned or leased by the Company or Platinum Bermuda in Bermuda.

     (xviii) The statements in the Offering Circular under the captions “Management’s
Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition,
Liquidity and Capital Resources—Liquidity Requirements,” “Business—Regulation—Bermuda Regulation”
and “Description of Our Share Capital,” to the extent that they constitute statements of Bermuda
law, are accurate in all material respects.

     (xix) The Company can sue and be sued in its own name under the laws of Bermuda.

     (xx) The choice of New York law as the governing law of this Agreement, the
Jurisdiction Agreement and the Notes Registration Rights is a valid choice of law and would be
recognized and given effect to in any action brought before a court of competent jurisdiction in
Bermuda, except for those laws (i) which such court considers to be procedural in nature, (ii)
which are revenue or penal laws or (iii) the application of which would be inconsistent with public
policy, as such term is interpreted under the laws of Bermuda. The submission in the Jurisdiction
Agreement to the non-exclusive jurisdiction of the New York Courts (as defined in the Jurisdiction
Agreement) is valid and binding upon the Company.

42

 

     (xxi) The courts of Bermuda would recognize as a valid judgment, a final and
conclusive judgment in personam, obtained in the New York Courts against the Company based upon
this Agreement, the Jurisdiction Agreement and the Notes Registration Rights Agreement and the
Indenture under which a sum of money is payable (other than a sum of money payable in respect of
multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty)
and would give a judgment based thereon provided that (a) such courts had proper jurisdiction over
the parties subject to such judgment, (b) such courts did not contravene the rules of natural
justice of Bermuda, (c) such judgment was not obtained by fraud, (d) the enforcement of the
judgment would not be contrary to the public policy of Bermuda, (e) no new admissible evidence
relevant to the action is submitted prior to the rendering of the judgment by the courts of Bermuda
and (f) there is due compliance in seeking validation of such judgment with the correct procedures
under the laws of Bermuda.

     (xxii) Under Section 16 of the Companies Act 1981, the bye-laws of the Company shall
bind the Company and the members of the Company to the same extent as if such bye-laws had been
signed and sealed by each such member, and contain covenants on the part of each such member to
observe all the provisions of the bye-laws of the Company, except, as provided in Section 17 of the
Companies Act 1981, no member of the Company shall be bound by an alteration made in the bye-laws
after the date on which he became a member, if and so far as the alteration requires him to take or
subscribe for more shares than the number held by him at the date on which the alteration is made,
or in any way increases his liability as at that date to contribute to the share capital of, or
otherwise to pay money to, the Company (unless the member agrees in writing, either before or after
the alteration is made, to be bound thereby).

     (xxiii) Based solely on a search of the Register of Charges, maintained by the
Registrar of Companies pursuant to Section 55 of the Companies Act 1981, conducted on the date
identified in such opinion, there are no registered charges registered against the Company or
Platinum Bermuda.

     (xxiv) Based solely upon a search of the Cause Book of the Supreme Court of Bermuda
conducted on the date identified in such opinion, there are no judgments, nor legal or governmental
proceedings pending in Bermuda to which either of the Company or Platinum Bermuda is a party.

     (xxv) The Remarketing Agents and the Reset Agent will not be deemed to be resident,
domiciled or carrying on business in Bermuda by reason only of the execution, performance and
enforcement of this Agreement, the Jurisdiction Agreement or the Notes Registration Rights
Agreement.

     (xxvi) Each of the Remarketing Agents, Reset Agent and Purchase Contract Agent has
standing to bring an action or proceedings before the appropriate courts in Bermuda for the
enforcement of this Agreement, the Jurisdiction Agreement and the Notes Registration Rights
Agreement. It is not necessary or advisable in order for the Remarketing Agents to enforce its
rights under this Agreement, the Jurisdiction

43

 

Agreement or the Notes Registration Rights Agreement, including the exercise of remedies
thereunder, that it be licensed, qualified or otherwise entitled to carry on business in Bermuda.

     (xxvii) The Company and Platinum Bermuda have been designated as non-resident for
the purposes of the Exchange Control Act, 1972 and as such are free to acquire, hold and sell
foreign currency (including the payment of dividends and other distributions) and securities
without restriction. No currency exchange control laws or withholding taxes of Bermuda apply to
the payment of dividends (a) on the Common Shares by the Company or (b) by Platinum Bermuda to the
Company, except in each case as described in or contemplated by the Offering Circular; and Platinum
Bermuda is not currently prohibited by any Bermuda law or governmental authority, directly or
indirectly, from paying any dividends to the Company, from making any other distributions on its
capital stock, from repaying to the Company any loans or advances to it from the Company or from
transferring any of its property or assets to the Company, except as contemplated by the Offering
Circular.

     (xxviii) Neither the Company nor Platinum Bermuda is entitled to any immunity under
the laws of Bermuda, whether characterized as sovereign immunity or otherwise, from any legal
proceedings to enforce this Agreement, the Jurisdiction Agreement or the Notes Registration Rights
Agreement in respect of itself or its property.

     (xxix) The procedure for the service of process on the Company through C.T.
Corporation System in New York, New York, United States of America, acting as agent for the
Company, as set out in Section 1(ee) of this Agreement and in the Jurisdiction Agreement and the
Notes Registration Rights Agreement, would be effective, in so far as Bermuda law is concerned, to
constitute valid service of the proceedings on the Company.

     (i) The Company has been duly qualified as a foreign corporation for the transaction of
business and is in good standing under the laws of each jurisdiction in which it owns or leases
properties or conducts any business so as to require such qualification, or is subject to no
material liability or disability by reason of failure to be so qualified in any such jurisdiction
(such counsel being entitled to rely in respect of the opinion in this clause upon opinions of
local counsel and in respect of matters of fact upon certificates of officers of the Company and of
public officials, provided that such counsel shall state that he believes that both you and he are
justified in relying upon such opinions and certificates);

     (ii) Platinum Finance has been duly qualified as a foreign corporation for the
transaction of business and is in good standing under the laws of each jurisdiction in which it
owns or leases properties or conducts any business so as to require such qualification, or is
subject to no material liability or disability by reason of failure to be so qualified in any such
jurisdiction (such counsel being entitled to rely in respect of the opinion in this clause upon
opinions of local counsel and in respect of matters of fact upon certificates of officers of
Platinum Finance and of public officials, provided that such counsel shall state that he believes
that both you and he are justified in relying upon such opinions and certificates);

     (iii) To the best of such counsel’s knowledge and other than as set forth in the
Offering Circular, there are no legal or governmental proceedings pending to which the Company or
any of its subsidiaries is a party or of which any property of the Company or any of its
subsidiaries is the subject which, if determined adversely to the Company or any of its
subsidiaries, would individually or in the aggregate have a material adverse effect on the
consolidated financial position, shareholders’ equity or results of operations of the Company and
its subsidiaries, taken as a whole; and, to the best of such counsel’s knowledge, no such
proceedings are threatened or contemplated by governmental authorities or threatened by others.

     (iv) The Remarketing of the Notes and the issuance and delivery of the Exchange
Securities pursuant to and in the manner contemplated by the Remarketing Agreement and the Notes
Registration Rights Agreement and the compliance by the Company and Platinum Finance with all of
the provisions of the Remarketing Agreement, the Jurisdiction Agreement, the Notes Registration
Rights Agreement and the Indenture and the consummation of the transactions therein contemplated
will not conflict with or result in a breach or violation of any of the terms or provisions of, or
constitute a default under, or give rise to a right of termination under, any of the Filed
Agreements or under any indenture, mortgage, deed of trust, loan agreement or other agreement or
instrument known to such counsel to which the Company or any of its subsidiaries is a party or by
which the Company or any of its subsidiaries is bound or to which any of the property or assets of

subsidiaries, taken as a whole, (B) would not affect the due authorization and enforceability in
accordance with their terms of the Notes; or (C) would not adversely affect the consummation of the

position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken
as a whole; (B) would not affect the due authorization and enforceability in accordance with their
terms of the Notes; or (C) would not adversely affect the consummation of the transactions
contemplated by the Remarketing Agreement, the Notes Registration Rights Agreement and the
Indenture; and

     (vi) Platinum US is duly licensed as an insurer or reinsurer, as the case may be,
under the Insurance Laws of each jurisdiction in which the conduct of its business requires such
licensing, except for such jurisdictions in which the failure of Platinum US to be so licensed
would not, individually or in the aggregate, have a material adverse effect on the consolidated
financial position, shareholders’ equity or results of operations of the Company and its
subsidiaries, taken as a whole. Platinum US has made all required filings under applicable
Insurance Laws in each jurisdiction where such filings are required, except for such jurisdictions
in which the failure to make such filings would not, individually or in the aggregate, have a
material adverse effect on the consolidated financial position, shareholder’s equity or results of

necessary authorizations, approvals, orders, consents, certificates, permits, registrations and
qualifications of and from all insurance regulatory authorities necessary to conduct its business
as described in the Offering Circular and all of the foregoing are in full force and effect, except
where the failure to have such authorizations, approvals, orders, consents, certificates, permits,
registrations or qualifications or their failure to be in full force and effect would not,
individually or in the aggregate, have a material adverse effect on the consolidated financial
position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken
as a whole. To such counsel’s knowledge, Platinum US has not received any notification from any
insurance regulatory authority or other governmental authority in the United States, Ireland, the

order, consent, certificate, permit, registration or qualification is needed to be obtained by
Platinum US; and, to such counsel’s knowledge, no insurance regulatory authority has issued any
order or decree

46

 

impairing, restricting or prohibiting the payment of dividends by Platinum US to its parent;

     Such counsel shall also furnish to you a written statement that nothing came to his attention
in the course of his review that has caused such counsel to believe that the Offering Circular, as
of its date, and the documents incorporated therein by reference which were filed under the
Exchange Act, as of their respective dates (in each case, other than the financial statements and
related notes and schedules and other financial information therein, as to which he need express no
opinion) contained any untrue statement of a material fact or omitted to state any material fact
necessary in order to make the statements therein, in the light of the circumstances under which
