Inc.

   As Representatives of the
   several Underwriters listed
   in Schedule 1 hereto

c/o J.P. Morgan Securities Inc.
277 Park Avenue
New York, New York 10172


Ladies and Gentlemen:

     Aircastle Limited, a Bermuda exempted company (the "Company"), proposes to
issue and sell to the several Underwriters listed in Schedule 1 hereto (the
"Underwriters"), for whom you are acting as representatives (the
"Representatives"), an aggregate of 13,500,000 common shares, par value U.S.
$0.01 per share, of the Company (the "Underwritten Shares") and, at the option
of the Underwriters, up to an additional 2,025,000 common shares of the Company
(the "Option Shares"). The Underwritten Shares and the Option Shares are herein
referred to as the "Shares." The common shares of the Company to be issued and
outstanding after giving effect to the sale of the Shares are herein referred to
as the "Stock."

     As part of the offering contemplated by this Agreement, the Underwriters
have agreed to reserve on a pro rata basis out of the Shares set forth opposite
their names on Schedule 1 to this Agreement, up to 1,552,500 of the common
shares, for sale to the Company's employees, officers, and directors and other
parties associated with the Company (collectively, "Participants") (the
"Directed Share Program"). The Shares to be sold by or on behalf of the
Underwriters pursuant to the Directed Share Program (the "Directed Shares") will
be sold pursuant to this Agreement at the public offering price. Any Directed
Shares not confirmed for purchase by any Participants via the Company's Directed
Share Program web site or orally by telephone by 8:00 A.M., New York City time,
on the day immediately following the date on which this Agreement is executed
will be offered to the public with the remaining Shares.

     The Company hereby confirms its agreement with the several Underwriters
concerning the purchase and sale of the Shares, as follows:

     1. Registration Statement. The Company has prepared and filed with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Securities Act"), a registration statement on Form S-1 (File
No. 333-140228), including a prospectus, relating to the Shares. Such
registration statement, as amended at the time it becomes effective, including
the information, if any, deemed pursuant to Rule 430A under the Securities Act
to be part of the registration statement at the time of its effectiveness ("Rule
430A Information"), is referred to herein as the "Registration Statement"; and
as used herein, the term "Preliminary Prospectus" means each prospectus included
in such registration statement (and any amendments thereto) before it becomes
effective (including any prospectus wrapper or Directed Share Program material
prepared by or with the consent of the Company for distribution in connection
with the Directed Share Program attached to or included with any preliminary
prospectus), any prospectus filed with the Commission pursuant to Rule 424(a)
under the Securities Act and the prospectus included in the Registration
Statement at the time of its effectiveness that omits Rule 430A Information, and
the term "Prospectus" means the final prospectus in the form first used (or made
available to the Underwriters for delivery, upon request of purchasers pursuant
to Rule 173 under the Securities Act) in connection with sales of the Shares
(including any prospectus wrapper or Directed Share Program material prepared by
or with the consent of the Company for distribution in connection with the
Directed Share Program attached to or included with final prospectus). If the
Company has filed an abbreviated registration statement pursuant to Rule 462(b)
under the Securities Act (the "Rule 462 Registration Statement"), then any
reference herein to the term "Registration Statement" shall be deemed to include
such Rule 462 Registration Statement. Capitalized terms used but not defined
herein shall have the meanings given to such terms in the Registration Statement
and the Prospectus.

     At or prior to the time when sales of the Shares were first made (the "Time
of Sale"), the Company had prepared the following information (collectively with
the pricing information set forth on Annex A, the "Time of Sale Information"): a
Preliminary Prospectus dated February 1, 2007, and each "free-writing
prospectus" (as defined pursuant to Rule 405 under the Securities Act) listed on
Annex B(ii) hereto.


     2. Purchase of the Shares by the Underwriters. (a) The Company agrees to
issue and sell the Shares to the several Underwriters as provided in this
Agreement, and each Underwriter, on the basis of the representations, warranties
and agreements set forth herein and subject to the conditions set forth herein,
agrees, severally and not jointly, to purchase from the Company the respective
number of Underwritten Shares set forth opposite such Underwriter's name in
Schedule 1 hereto at a price per share (the "Purchase Price") of U.S. $31.845.

     In addition, the Company agrees to issue and sell the Option Shares to the
several Underwriters as provided in this Agreement, and the Underwriters, on the
basis of the representations, warranties and agreements set forth herein and
subject to the conditions set forth herein, shall have the option to purchase,
severally and not jointly, from the Company the Option Shares at the Purchase
Price less an amount equal to any dividends or distributions paid or payable on
the Underwritten Shares but not payable on such Option Shares.

     If any Option Shares are to be purchased, the number of Option Shares to be
purchased by each Underwriter shall be the number of Option Shares which bears
the same ratio to the aggregate number of Option Shares being purchased as the
number of Underwritten Shares set forth opposite the name of such Underwriter in
Schedule 1 hereto (or such number increased as set forth in Section 10 hereof)
bears to the aggregate number of Underwritten Shares being purchased from the
Company by the several Underwriters, subject, however, to such adjustments to
eliminate any fractional Shares as the Representatives in their sole discretion
shall make.

     The Underwriters may exercise the option to purchase the Option Shares at
any time in whole, or from time to time in part, on or before the thirtieth day
following the date of this Agreement, by written notice from the Representatives
to the Company. Such notice shall set forth the aggregate number of Option
Shares as to which the option is being exercised and the date and time when the
Option Shares are to be issued and paid for which may be the same date and time
as the Closing Date (as hereinafter defined) but shall not be earlier than the
Closing Date nor later than the tenth full business day (as hereinafter defined)
after the date of such notice (unless such time and date are postponed in
accordance with the provisions of Section 10 hereof). Any such notice shall be
given at least two business days prior to the date and time of issue specified
therein.

     (b) The Company understands that the Underwriters intend to make a public
offering of the Shares as soon after the effectiveness of this Agreement as in
the judgment of the Representatives is advisable, and initially to offer the
Shares on the terms set forth in the Prospectus. The Company acknowledges and
agrees that the Underwriters may offer and sell Shares to or through any
affiliate of an Underwriter and that any such affiliate may offer and sell
Shares purchased by it to or through any Underwriter.

     (c) Payment for the Shares shall be made by wire transfer in immediately
available funds to the account specified by the Company to the Representatives
in the case of the Underwritten Shares, at the offices of Sidley Austin LLP at
10:00 A.M., New York City time, on February 13, 2007, or at such other time or
place on the same or such other date, not later than the fifth business day
thereafter, as the Representatives and the Company may agree upon in writing or,
in the case of the Option Shares, on the date and at the time and place
specified by the Representatives in the written notice of the Underwriters'
election to purchase such Option Shares. The time and date of such payment for
the Underwritten Shares is referred to herein as the "Closing Date" and the time
and date for such payment for the Option Shares, if other than the Closing Date,
is herein referred to as the "Additional Closing Date."

     Payment for the Shares to be purchased on the Closing Date or the
Additional Closing Date, as the case may be, shall be made against issue to the
Representatives for the respective accounts of the several Underwriters of the
Shares to be purchased on such date in definitive form registered in such names
and in such denominations as the Representatives shall request in writing not
later than two full business days prior to the Closing Date or the Additional
Closing Date, as the case may be, with any transfer taxes payable in connection
with the sale of the Shares duly paid by the Company. The certificates for the
Shares will be made available for inspection and packaging by the
Representatives at the office of J.P. Morgan Securities Inc. set forth above not
later than 1:00 P.M., New York City time, on the business day prior to the
Closing Date or the Additional Closing Date, as the case may be.

     (d) The Company acknowledges and agrees that the Underwriters are acting
solely in the capacity of an arm's length contractual counterparty to the
Company with respect to the offering of Shares contemplated hereby (including in
connection with determining the terms of the offering) and not as a financial
advisor or a fiduciary to, or an agent of, the Company or any other person.
Additionally, none of the Representatives or other Underwriters are advising the
Company or any other person as to any legal, tax, investment, accounting or
regulatory matters in any jurisdiction. The Company shall consult with its own
advisors concerning such matters and shall be responsible for making its own
independent investigation and appraisal of the transactions contemplated hereby,
and the Underwriters shall have no responsibility or liability to the Company
with respect thereto. Any review by the Underwriters of the Company, the
transactions contemplated hereby or other matters relating to such transactions
will be performed solely for the benefit of the Underwriters and shall not be on
behalf of the Company.

     3. Representations and Warranties of the Company. The Company represents
and warrants to each Underwriter that:

     (a) Preliminary Prospectus. No order preventing or suspending the use of
any Preliminary Prospectus has been issued by the Commission, and each
Preliminary Prospectus, at the time of filing thereof, complied in all material
respects with the Securities Act and did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided that the
Company makes no representation and warranty with respect to any statements or
omissions made in reliance upon and in conformity with information relating to
any Underwriter furnished to the Company in writing by such Underwriter through
the Representatives expressly for use in any Preliminary Prospectus.

     (b) Time of Sale Information. The Time of Sale Information, at the Time of
Sale did not, and at the Closing Date and as of the Additional Closing Date, as
the case may be, will not, contain any untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading;
provided that the Company makes no representation and warranty with respect to
any statements or omissions made in reliance upon and in conformity with
information relating to any Underwriter furnished to the Company in writing by
such Underwriter through the Representatives expressly for use in such Time of
Sale Information. No statement of material fact included in the Prospectus has
been omitted from the Time of Sale Information and no statement of material fact
included in the Time of Sale Information that is required to be included in the
Prospectus has been omitted therefrom.

     (c) Issuer Free Writing Prospectus. Other than the Preliminary Prospectus
and the Prospectus, the Company (including its agents and representatives, other
than the Underwriters in their capacity as such) has not made, used, prepared,
authorized, approved or referred to and will not prepare, make, use, authorize,
approve or refer to any "written communication" (as defined in Rule 405 under
the Securities Act) that constitutes an offer to sell or solicitation of an
offer to buy the Shares (each such communication by the Company or its agents
and representatives (other than a communication referred to in clause (i) below)
an "Issuer Free Writing Prospectus") other than (i) any document not
constituting a prospectus pursuant to Section 2(a)(10)(a) of the Securities Act
or Rule 134 under the Securities Act or (ii) the documents listed on Annex B(i)
or Annex B(ii) hereto and other written communications approved in writing in
advance by the Representatives. Each such Issuer Free Writing Prospectus
complied in all material respects with the Securities Act, has been filed in
accordance with the Securities Act (to the extent required thereby) and, when
taken together with the Preliminary Prospectus accompanying, or delivered prior
to delivery of, such Issuer Free Writing Prospectus, did not, and at the Closing
Date and as of the Additional Closing Date, as the case may be, will not,
contain any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided that the
Company makes no representation and warranty with respect to any statements or
omissions made in each such Issuer Free Writing Prospectus in reliance upon and
in conformity with information relating to any Underwriter furnished to the
Company in writing by such Underwriter through the Representatives expressly for
use in any Issuer Free Writing Prospectus.

     (d) Registration Statement and Prospectus. The Registration Statement has
been declared effective by the Commission. No order suspending the effectiveness
of the Registration Statement has been issued by the Commission and, to the
Company's knowledge, no proceeding for that purpose or pursuant to Section 8A of
the Securities Act against the Company or related to the offering has been
initiated or, to the Company's knowledge, is contemplated or threatened by the
Commission; as of the applicable effective date of the Registration Statement
and any amendment thereto, the Registration Statement complied and will comply
in all material respects with the Securities Act, and neither the Registration
Statement nor any amendment thereto contained or will contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading; and as of the date of the Prospectus and any amendment or supplement
thereto and as of the Closing Date and as of the Additional Closing Date, as the
case may be, neither the Prospectus nor any amendment or supplement thereto will
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided that the Company makes no representation and warranty with
respect to any statements or omissions made in reliance upon and in conformity
with information relating to any Underwriter furnished to the Company in writing
by such Underwriter through the Representatives expressly for use in the
Registration Statement and the Prospectus and any amendment or supplement
thereto.

     (e) Financial Statements. The financial statements together with the
related notes thereto of the Company and its consolidated subsidiaries included
in the Registration Statement, the Time of Sale Information and the Prospectus
comply in all material respects with the applicable requirements of the
Securities Act and present fairly in all material respects the financial
position of the Company and its subsidiaries as of the dates indicated and the
results of their operations and the changes in their cash flows for the periods
specified; such financial statements have been prepared in conformity with U.S.
generally accepted accounting principles applied on a consistent basis
throughout the periods covered thereby, and the supporting schedules, if any,
included in the Registration Statement present fairly in all material respects
the information required to be stated therein; and the other financial
information included in the Registration Statement, the Time of Sale Information
and the Prospectus has been derived from the accounting records of the Company

forma financial statements or the financial statements of any other business or
entity in the Registration Statement, the Time of Sale Information or the
Prospectus under the Securities Act.

     (f) No Material Adverse Change. Since the date of the most recent financial
statements of the Company included in the Registration Statement, the Time of
Sale Information and the Prospectus, except in each case as otherwise disclosed
in the Registration Statement, the Time of Sale Information and the Prospectus,
(i) there has not been any change in the share capital or long-term debt of the
Company or any of its subsidiaries, or any dividend or distribution of any kind
declared, set aside for payment, paid or made by the Company on any class of
shares, or any material adverse change, or any development involving a
prospective material adverse change, in or affecting the business, properties,
management, financial position, shareholders' equity, results of operations or
prospects of the Company and its subsidiaries taken as a whole (other than
changes (a) in the ordinary course of business in amounts outstanding under the
Company's credit facilities or repurchase agreements described in the
Registration Statement, the Time of Sale Information and the Prospectus, or (b)
due to issuances of the Company's common shares or securities convertible or

benefit and option plans described in the Registration Statement, the Time of
Sale Information and the Prospectus, including the settlement of a restricted
share award), (ii) neither the Company nor any of its subsidiaries has entered

any loss or interference with its business from fire, explosion, flood or other

subsidiaries taken as a whole.

     (g) Organization and Good Standing. The Company and each "significant
subsidiary" (as defined in Rule 1-02 of Regulation S-X) of the Company, which

have been duly organized and are validly existing and in good standing under the
laws of their respective jurisdiction of incorporation or formation, as

jurisdiction in which their respective ownership or lease of property or the
conduct of their respective businesses requires such qualification, and have all
power and authority necessary to own or hold their respective properties and to
conduct the businesses in which they are engaged, except where the failure to be
so qualified or have such power or authority would not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on the
business, properties, management, financial position, shareholders' equity,
results of operations or prospects of the Company and its subsidiaries taken as
a whole (a "Material Adverse Effect"). The Company does not own or control,
directly or indirectly, any company, corporation, association or other entity
other than (i) the subsidiaries listed in Exhibit 21.1 to the Registration
Statement and (ii) subsidiaries, if considered in the aggregate as a single

relating to the issuance of shares in the capital of the Company or any such
subsidiary, any such convertible or exchangeable securities or any such rights,
warrants or options; the share capital of the Company conforms in all material
respects to the description thereof contained in the Registration Statement, the
Time of Sale Information and the Prospectus; and all the outstanding shares or
other equity interests of each Significant Subsidiary of the Company have been

or regulatory authority, except, in the case of clause (i) above, with respect
to subsidiaries of the Company other than the Significant Subsidiaries and in
the case of clauses (ii) and (iii) above, for any such default or violation that
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

     (m) No Conflicts. The execution, delivery and performance by the Company of
this Agreement, the issuance and sale of the Shares and the consummation of the
transactions contemplated by this Agreement will not (i) conflict with or result
in a breach or violation of any of the terms or provisions of, or constitute a

except, in each case, as would not have a Material Adverse Effect.

     (x) Compliance With Environmental Laws. (i) The Company and its
subsidiaries (x) are in compliance with any and all applicable Bermuda, Ireland,
U.S. federal, state and local and foreign laws, rules, regulations,

Adverse Effect.

     (y) Compliance With ERISA. Each employee benefit plan, within the meaning
of Section 3(3) of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), that is maintained, administered or contributed to by the
Company or any of its affiliates for employees or former employees of the
Company and its affiliates has been maintained in compliance in all material
respects with its terms and the requirements of any applicable statutes, orders,
rules and regulations, including but not limited to ERISA and the Internal

the meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred
with respect to any such plan excluding transactions effected pursuant to a

"accumulated funding deficiency" as defined in Section 412 of the Code has been
incurred, whether or not waived, and the fair market value of the assets of each
such plan (excluding for these purposes accrued but unpaid contributions)
exceeds the present value of all benefits accrued under such plan determined
using reasonable actuarial assumptions.

     (z) Accounting and Disclosure Controls. The Company (individually and on a
consolidated basis) and its subsidiaries maintain systems of "internal control
over financial reporting" (as defined in Rule 13a-15(f) of the Securities
Exchange Act of 1934, as amended, and the rules and regulations of the
Commission thereunder (collectively, the "Exchange Act")), that complies with
the requirements of the Exchange Act and has been designed by the Company's
principal executive officer and principal financial officer, or under their
supervision, sufficient to provide reasonable assurance that: (i) transactions
are executed in accordance with management's general or specific authorizations;
(ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with U.S. generally accepted accounting principles and
to maintain asset accountability; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences. The Company's internal control over financial reporting is
effective and the Company is not aware of any material weakness in its internal
control over financial reporting.

     Since the date of the latest audited financial statements of the Company
included in the Prospectus, there has been no change in the Company's internal
control over financial reporting that has materially affected, or is reasonably
likely to materially affect, the Company's internal control over financial
reporting.

     The Company maintains disclosure controls and procedures (as such term is
defined in Rule 13a-15(e) under the Exchange Act) that comply with the
requirements of the Exchange Act; such disclosure controls and procedures have
been designed to ensure that material information relating to the Company and
its subsidiaries is made known to the Company's principal executive officer and
principal financial officer by others within those entities; and such disclosure
controls and procedures are effective.

     (aa) Insurance. The Company and its subsidiaries have insurance covering
their respective properties, operations, personnel and businesses, including
business interruption insurance, which insurance is in amounts and insures
against such losses and risks as are customary for entities engaged in similar
businesses in similar industries and as are adequate in accordance with the
Company's reasonable business judgment to protect the Company and its
subsidiaries and their respective businesses; and neither the Company nor any of
its subsidiaries has (i) received notice from any insurer or agent of such
insurer that material capital improvements or other material expenditures are
required or necessary to be made in order to continue such insurance or (ii) any
reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage at
reasonable cost from similar insurers as may be necessary to continue its
business.

     (bb) No Unlawful Payments. None of the Company, any of the Company's
subsidiaries or, to the knowledge of the Company, any director, officer, agent,
employee or other person associated with or acting on behalf of the Company or

contribution, gift, entertainment or other unlawful expense relating to
political activity, (ii) made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds, (iii)
violated or is in violation of any provision of the Foreign Corrupt Practices
Act of 1977 or (iv) made any bribe, rebate, payoff, influence payment, kickback
or other unlawful payment.

and its subsidiaries are and have been conducted at all times in compliance in
all material respects with applicable financial recordkeeping and reporting
requirements of the Currency and Foreign Transactions Reporting Act of 1970, as
amended, the money laundering statutes of all jurisdictions, the rules and
regulations thereunder and any related or similar rules, regulations or
guidelines, issued, administered or enforced by any governmental agency
(collectively, the "Money Laundering Laws") and no action, suit or proceeding by
or before any court or governmental agency, authority or body or any arbitrator
involving the Company or any of its subsidiaries with respect to the Money
Laundering Laws is pending or, to the knowledge of the Company, threatened.

     (dd) Compliance with OFAC. None of the Company, any of the Company's
subsidiaries or, to the knowledge of the Company, any director, officer, agent,
employee or Affiliate of the Company or any of its subsidiaries is currently
subject to any U.S. sanctions administered by the Office of Foreign Assets
Control of the U.S. Department of the Treasury ("OFAC"); and the Company will
not directly or indirectly use the proceeds of the offering of the Shares
hereunder, or lend, contribute or otherwise make available such proceeds to any
subsidiary, joint venture partner or other person or entity, for the purpose of
financing the activities of any person currently subject to any U.S. sanctions
administered by OFAC.

     (ee) No Restrictions on Subsidiaries. Except as set forth in the
Registration Statement, the Time of Sale Information and the Prospectus, no

any agreement or other instrument to which it is a party or is subject, from
paying any dividends to the Company, from making any other distribution on such
subsidiary's capital stock, from repaying to the Company any loans or advances
to such subsidiary from the Company or from transferring any of such
subsidiary's properties or assets to the Company or any other subsidiary of the
Company.

     (ff) No Broker's Fees. Neither the Company nor any of its subsidiaries is a
party to any contract, agreement or understanding with any person (other than

of its subsidiaries or any Underwriter for a brokerage commission, finder's fee
or like payment in connection with the offering and sale of the Shares.

     (gg) No Registration Rights. Except as set forth in the Registration
Statement, the Time of Sale Information and the Prospectus, no person has the
right to require the Company or any of its subsidiaries to register any
securities for sale under the Securities Act by reason of the filing of the
Registration Statement with the Commission or the issuance and sale of the
Shares.

     (hh) No  Stabilization.  The Company has not taken,  directly or indirectly
(without  giving  any  effect to  activities  by the  Underwriters),  any action
designed  to or that  could  reasonably  be  expected  to cause or result in any
stabilization or manipulation of the price of the Shares.

     (ii) Forward-Looking Statements. No forward-looking statement (within the
meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act) contained in the Registration Statement, the Time of Sale Information or
the Prospectus has been made or reaffirmed without a reasonable basis or has
been disclosed other than in good faith.

     (jj) Statistical and Market Data. Nothing has come to the attention of the
Company that has caused the Company to believe that the statistical and
market-related data included in the Registration Statement, the Time of Sale
Information or the Prospectus is not based on or derived from sources that are
reliable and accurate in all material respects.

     (mm) Directed Share Program. The Registration Statement, the Prospectus and
the Time of Sale Information comply, and any further amendments or supplements
thereto will comply, in all material respects, with any applicable laws or
regulations of each jurisdiction in which the Time of Sale Information or the

than as disclosed in the Registration Statement, the Time of Sale Information
and the Prospectus, no regulatory agency or body or other governmental authority

supplemented would include any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances existing when the
Prospectus, the Time of Sale Information or any such Issuer Free Writing
Prospectus is delivered to a purchaser, not misleading and (vii) of the receipt
by the Company of any notice with respect to any suspension of the qualification

best efforts to prevent the issuance of any such order suspending the
effectiveness of the Registration Statement, preventing or suspending the use of
any Preliminary Prospectus or the Prospectus or suspending any such

the circumstances, be misleading or so that the Time of Sale Information will
comply with law.

     (f) Blue Sky Compliance. The Company will qualify the Shares for offer and
sale under the securities or Blue Sky laws of such jurisdictions as the

to its broad unrestricted dissemination.

     (c) It has not and will not, without the prior written consent of the

retain copies of each free writing prospectus used or referred to by it, in
accordance with Rule 433 under the Securities Act.

defined by the Commission for purposes of Rule 436(g)(2) under the Securities
Act and (ii) no such organization shall have publicly announced that it has
under surveillance or review, or has changed its outlook with respect to, its
rating of any debt securities of or guaranteed by the Company or any of its
subsidiaries (other than an announcement with positive implications of a
possible upgrading).

     (d) No Material Adverse Change. No event or condition of a type described
in Section 3(f) hereof shall have occurred or shall exist, which event or
condition is not described in the Time of Sale Information (excluding any

Representatives makes it impracticable or inadvisable to proceed with the

Closing Date, as the case may be, on the terms and in the manner contemplated by
this Agreement, the Time of Sale Information and the Prospectus.

     (e) Officer's Certificate. The Representatives shall have received on and

case may be, an opinion of Sidley Austin LLP, counsel for the Underwriters, with
respect to such matters as the Representatives may reasonably request, and such
counsel shall have received such documents and information as they may
reasonably request to enable them to pass upon such matters.

     (i) No Legal Impediment to Issuance. No action shall have been taken and no
statute, rule, regulation or order shall have been enacted, adopted or issued by
any Bermuda or U.S. federal or state or foreign governmental or regulatory
authority that would, as of the Closing Date or the Additional Closing Date, as

     (j) Good Standing. The Representatives shall have received on and as of the
Closing Date or the Additional Closing Date, as the case may be, satisfactory
evidence of the good standing of the Company and its Significant Subsidiaries in

provisions hereof only if they are in form and substance reasonably satisfactory

     7. Indemnification and Contribution.

     (a) Indemnification of the Underwriters. The Company agrees to indemnify
and hold harmless each Underwriter, its affiliates, directors and officers and
each person, if any, who controls such Underwriter within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act from and against any
and all losses, claims, damages and liabilities (including, without limitation,
legal fees and other expenses incurred in connection with any suit, action or
proceeding or any claim asserted, as such fees and expenses are incurred), joint
or several, that arise out of, or are based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, not misleading or (ii) any untrue statement or alleged
untrue statement of a material fact contained in the Prospectus (or any
amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time
of Sale Information (including any Time of Sale Information that has
subsequently been amended) or caused by any omission or alleged omission to
state therein a material fact necessary in order to make the statements therein,
in light of the circumstances under which they were made, not misleading, in
each case except insofar as such losses, claims, damages or liabilities arise
out of, or are based upon, any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with any
information relating to any Underwriter furnished to the Company in writing by
such Underwriter through the Representatives expressly for use therein, it being
understood and agreed that the only such information furnished by any
Underwriter consists of the information described as such in subsection (b)
below.

     The Company agrees to indemnify and hold harmless the Underwriters and any
selling group member participating in the Directed Share Program, their
affiliates, directors and officers and each person who controls each Underwriter
or any selling group member participating in the Directed Share Program within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act from and against any and all losses, claims, damages and liabilities
(including, without limitation, legal fees and other expenses incurred in
connection with any suit, action or proceeding or any claim asserted, as such
fees and expenses are incurred), joint or several, that (i) arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in the prospectus wrapper or Directed Share Program material prepared
by or with the consent of the Company for distribution in connection with the
Directed Share Program attached to or included with the Prospectus or any
preliminary prospectus, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statement therein, when considered in conjunction with
the Prospectus or any applicable preliminary prospectus, not misleading, (ii)
are caused by the failure of any Participant to pay for and accept delivery of
the Shares which were subject to a properly confirmed agreement to purchase or
(iii) are related to, arise out of, or are in connection with the Directed Share
Program, except that this clause (iii) shall not apply to the extent that such
loss, claim, damage or liability is finally judicially determined to have
resulted from the bad faith, gross negligence or willful misconduct of the
Underwriters or any selling group member participating in the Directed Share
Program.

     (b) Indemnification of the Company. Each Underwriter agrees, severally and
not jointly, to indemnify and hold harmless the Company, its directors, its
officers who signed the Registration Statement and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the indemnity set forth in
paragraph (a) above, but only with respect to any losses, claims, damages or
liabilities that arise out of, or are based upon, any untrue statement or
omission or alleged untrue statement or omission made in reliance upon and in
conformity with any information relating to such Underwriter furnished to the
Company in writing by such Underwriter through the Representatives expressly for
use in the Registration Statement, the Prospectus (or any amendment or
supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale
Information, it being understood and agreed upon that the only such information
furnished by any Underwriter consists of the following information in the
Prospectus furnished on behalf of each Underwriter: (i) the concession and
reallowance figures appearing in the first and second sentences of the fourth
paragraph under the caption "Underwriting," (ii) the third, fourth and fifth
sentences of the fourth paragraph under the caption "Underwriting," (iii) the
eighth, fifteenth and sixteenth paragraphs under the caption "Underwriting" and
(iv) the second and third sentences of the seventeenth paragraph under the
caption "Underwriting."

     (c) Notice and Procedures. If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any person in respect of which indemnification may be sought
pursuant to either paragraph (a) or (b) above, such person (the "Indemnified
Person") shall promptly notify the person against whom such indemnification may
be sought (the "Indemnifying Person") in writing; provided that the failure to
notify the Indemnifying Person shall not relieve it from any liability that it
may have under this Section 7 except to the extent that it has been materially
prejudiced (through the forfeiture of substantive rights or defenses) by such
failure; and provided, further, that the failure to notify the Indemnifying
Person shall not relieve it from any liability that it may have to an
Indemnified Person otherwise than under this Section 7. If any such proceeding
shall be brought or asserted against an Indemnified Person and it shall have
notified the Indemnifying Person thereof, the Indemnifying Person shall retain
counsel reasonably satisfactory to the Indemnified Person (who shall not,
without the consent of the Indemnified Person, be counsel to the Indemnifying
Person) to represent the Indemnified Person in such proceeding and shall pay the
fees and expenses of such counsel related to such proceeding, as incurred. In
any such proceeding, any Indemnified Person shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed to the contrary, (ii) the
Indemnifying Person has failed within a reasonable time to retain counsel
reasonably satisfactory to the Indemnified Person, (iii) the Indemnifying Person
does not diligently defend the action after assumption of the defense or (iv)
such Indemnified Person or Persons shall have reasonably concluded that there
may be defenses available to it or them which are different from or additional
to those available to one or all of the Indemnifying Persons (in which case the
Indemnifying Persons shall not have the right to direct the defense of such
action on behalf of the Indemnified Person or Persons). It is understood and
agreed that the Indemnifying Person shall not, in connection with any proceeding
or related proceeding in the same jurisdiction, be liable for the fees and
expenses of more than one separate firm (in addition to any local counsel) for
all Indemnified Persons, and that all such fees and expenses shall be paid or
reimbursed as they are incurred; provided, however that if indemnity may be
sought pursuant to the second paragraph of Section 7(a) above in respect of such
action or proceeding, then in addition to such separate firm of the
Underwriters, their affiliates and such control persons of the Underwriters, the
Indemnifying Party shall be liable for the reasonable fees and expenses of not
more than one separate firm (in addition to any local counsel) for Citigroup
Global Markets Inc., the directors, officers, employees and agents of Citigroup
Global Markets Inc., and all persons, if any, who control Citigroup Global
Markets Inc. within the meaning of either the Act or the Exchange Act for the
defense of any losses, claims, damages and liabilities arising out of the
Directed Share Program. Any such separate firm for any Underwriter, its
affiliates, directors and officers and any control persons of such Underwriter
shall be designated in writing by J.P. Morgan Securities Inc. and any such
separate firm for the Company, its directors, its officers who signed the
Registration Statement and any control persons of the Company shall be
designated in writing by the Company. The Indemnifying Person shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified
Person shall have requested that an Indemnifying Person reimburse the
Indemnified Person for fees and expenses of counsel as contemplated by this
paragraph, the Indemnifying Person shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 60 days after receipt by the Indemnifying Person of such
request and, (ii) the Indemnifying Person shall not have reimbursed the
Indemnified Person in accordance with such request prior to the date of such
settlement. No Indemnifying Person shall, without the written consent of the
Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party and indemnification could have been sought hereunder by such Indemnified
Person, unless such settlement (x) includes an unconditional release of such
Indemnified Person, in form and substance reasonably satisfactory to such
Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (y) does not include any statement as to or any admission of
fault, culpability or a failure to act by or on behalf of any Indemnified
Person.

     (d) Contribution. If the indemnification provided for in paragraphs (a) and
(b) above is unavailable to an Indemnified Person or insufficient in respect of
any losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company, on the one hand, and the Underwriters (both in
their capacity as underwriters and in connection with the Directed Share
Program), on the other, from the offering of the Shares or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) but also the relative fault of the Company, on the one hand,
and the Underwriters (both in their capacity as underwriters and in connection
with the Directed Share Program), on the other, in connection with the
statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative benefits received by the Company, on the one hand, and the Underwriters
(both in their capacity as underwriters and in connection with the Directed
Share Program), on the other, shall be deemed to be in the same respective
proportions as the net proceeds (before deducting expenses) received by the
Company from the sale of the Shares and the total underwriting discounts and
commissions received by the Underwriters in connection therewith, in each case
as set forth in the table on the cover of the Prospectus, bear to the aggregate
offering price of the Shares. The relative fault of the Company, on the one
hand, and the Underwriters (both in their capacity as underwriters and in
connection with the Directed Share Program), on the other, 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 to state a
material fact relates to information supplied by the Company or by the
Underwriters (both in their capacity as underwriters and in connection with the
Directed Share Program), and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     (e) Limitation on Liability. The Company and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in paragraph (d) above. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses incurred by such Indemnified Person in connection with any such
action or claim. Notwithstanding the provisions of this Section 7, in no event
shall an Underwriter be required to contribute any amount in excess of the
amount by which the total underwriting discounts and commissions received by
such Underwriter with respect to the offering of the Shares exceeds the amount
of any damages that such Underwriter has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute pursuant to this Section 7 are several
in proportion to their respective purchase obligations hereunder and not joint.

     (f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are
not exclusive and shall not limit any rights or remedies which may otherwise be
available to any Indemnified Person at law or in equity.

     8.  Effectiveness of Agreement.  This Agreement shall become effective upon
the execution and delivery hereof by the parties hereto.

     9. Termination. This Agreement may be terminated in the absolute discretion
of the Representatives, by notice to the Company, if after the execution and
delivery of this Agreement and prior to the Closing Date or, in the case of the
Option Shares, prior to the Additional Closing Date, (i) trading generally shall
have been suspended or materially limited on or by any of the NYSE, the American
Stock Exchange, the National Association of Securities Dealers, Inc., the
Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago
Board of Trade, (ii) trading of any securities issued or guaranteed by the
Company shall have been suspended on any exchange or in any over-the-counter
market, (iii) a general moratorium on commercial banking activities shall have
been declared by U.S. federal or New York State or Bermuda authorities or a
material disruption in commercial banking or securities settlement or clearance
services in the United States or (iv) there shall have occurred any outbreak or
escalation of hostilities or any change in financial markets or any calamity or
crisis, either within or outside the United States, that, in the judgment of the
Representatives, is material and adverse and makes it impracticable or
inadvisable to proceed with the offering, sale or delivery of the Shares on the
Closing Date or the Additional Closing Date, as the case may be, on the terms
and in the manner contemplated by this Agreement, the Time of Sale Information
and the Prospectus.

     10. Defaulting Underwriter. (a) If, on the Closing Date or the Additional
Closing Date, as the case may be, any Underwriter defaults on its obligation to
purchase the Shares that it has agreed to purchase hereunder on such date, the
non-defaulting Underwriters may in their discretion arrange for the purchase of
such Shares by other persons satisfactory to the Company on the terms contained
in this Agreement. If, within 36 hours after any such default by any
Underwriter, the non-defaulting Underwriters do not arrange for the purchase of
such Shares, then the Company shall be entitled to a further period of 36 hours
within which to procure other persons satisfactory to the non-defaulting
Underwriters to purchase such Shares on such terms. If other persons become
obligated or agree to purchase the Shares of a defaulting Underwriter, either
the non-defaulting Underwriters or the Company may postpone the Closing Date or
the Additional Closing Date, as the case may be, for up to five full business
days in order to effect any changes that in the opinion of counsel for the
Company or counsel for the Underwriters may be necessary in the Registration
Statement and the Prospectus or in any other document or arrangement, and the
Company agrees to promptly prepare any amendment or supplement to the
Registration Statement and the Prospectus that effects any such changes. As used
in this Agreement, the term "Underwriter" includes, for all purposes of this
Agreement unless the context otherwise requires, any person not listed in
Schedule 1 hereto that, pursuant to this Section 10, purchases Shares that a
defaulting Underwriter agreed but failed to purchase.

     (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by the non-defaulting
Underwriters and the Company as provided in paragraph (a) above, the aggregate
number of Shares that remain unpurchased on the Closing Date or the Additional
Closing Date, as the case may be, does not exceed one-eleventh of the aggregate
number of Shares to be purchased on such date, then the Company shall have the
right to require each non-defaulting Underwriter to purchase the number of
Shares that such Underwriter agreed to purchase hereunder on such date plus such
Underwriter's pro rata share (based on the number of Shares that such
Underwriter agreed to purchase on such date) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made.

     (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by the non-defaulting
Underwriters and the Company as provided in paragraph (a) above, the aggregate
number of Shares that remain unpurchased on the Closing Date or the Additional
Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount
of Shares to be purchased on such date, or if the Company shall not exercise the
right described in paragraph (b) above, then this Agreement or, with respect to
any Additional Closing Date, the obligation of the Underwriters to purchase
Shares on the Additional Closing Date, as the case may be, shall terminate
without liability on the part of the non-defaulting Underwriters. Any
termination of this Agreement pursuant to this Section 10 shall be without
liability on the part of the Company, except that the Company will continue to
be liable for the payment of expenses as set forth in Section 11 hereof and
except that the provisions of Section 7 hereof shall not terminate and shall
remain in effect.

     (d) Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company or any non-defaulting Underwriter for
damages caused by its default.

     11. Payment of Expenses. (a) Whether or not the transactions contemplated
by this Agreement are consummated or this Agreement is terminated, the Company
will pay or cause to be paid all costs and expenses incident to the performance
of its obligations hereunder, including without limitation, (i) the costs
incident to the authorization, issuance, sale, preparation and delivery of the
Shares and any taxes payable in connection therewith, (ii) the costs incident to
the preparation, printing and filing under the Securities Act of the
Registration Statement, the Preliminary Prospectus, any Issuer Free Writing
Prospectus, any Time of Sale Information and the Prospectus (including all
exhibits, amendments and supplements thereto) and the distribution thereof,
(iii) the costs of reproducing and distributing this Agreement, (iv) the fees
and expenses of the Company's counsel and independent accountants, (v) the fees
and expenses incurred in connection with the registration or qualification and
determination of eligibility for investment of the Shares under the laws of such
jurisdictions as the Representatives may designate and the preparation, printing
and distribution of a Blue Sky Memorandum (including the related fees and
expenses of counsel for the Underwriters), (vi) the cost of preparing share
certificates, (vii) the costs and charges of any transfer agent and any
registrar, (viii) all expenses and application fees incurred in connection with
any filing with, and clearance of the offering by, the National Association of
Securities Dealers, Inc. (ix) all expenses incurred by the Company in connection
with any "road show" presentation to potential investors, (x) all expenses and
application fees related to the listing of the Shares on the Exchange and (xi)
all fees and disbursements of counsel incurred by the Underwriters in connection
with the Directed Share Program, including the printing (or reproduction) and
delivery (including postage, air freight charges and charges for counting and
packaging) of such copies of any prospectus wrapper or the Directed Share
Program material and stamp duties, similar taxes or duties or other taxes, if
any, incurred by the Underwriters in connection with the Directed Share Program.

     (b) If (i) this Agreement is terminated pursuant to clause (ii) of Section
9 hereof, (ii) the Company for any reason fails to tender the Shares for
delivery to the Underwriters or (iii) the Underwriters decline to purchase the
Shares for any reason permitted under this Agreement (other than following
termination of this Agreement pursuant to clauses (i), (iii) or (iv) of Section
9 hereof), the Company agrees to reimburse the Underwriters for all
out-of-pocket costs and expenses (including the fees and expenses of their
counsel) reasonably incurred by the Underwriters in connection with this
Agreement and the offering contemplated hereby.

     12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective
successors and the officers and directors and any controlling persons referred
to in Section 7 hereof. Nothing in this Agreement is intended or shall be
construed to give any other person any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein. No
purchaser of Shares from any Underwriter shall be deemed to be a successor
merely by reason of such purchase.

     13. Survival. The respective indemnities, rights of contribution,
representations, warranties and agreements of the Company and the Underwriters
contained in this Agreement or made by or on behalf of the Company or the
Underwriters pursuant to this Agreement or any certificate delivered pursuant
hereto shall survive the delivery of and payment for the Shares and shall remain
in full force and effect, regardless of any termination of this Agreement or any
investigation made by or on behalf of the Company or the Underwriters.

     14. Certain Defined Terms. For purposes of this Agreement, (a) except where
otherwise expressly provided, the term "affiliate" has the meaning set forth in
Rule 405 under the Securities Act; (b) the term "business day" means any day
other than a day on which banks are permitted or required to be closed in New
York City; and (c) the term "subsidiary" has the meaning set forth in Rule 405
under the Securities Act.

     15. Submission to Jurisdiction; Process Agent; Waiver of Trial by Jury. The

out of or based upon this Agreement or the transactions contemplated hereby may
be instituted in any state or federal court located in the Borough of Manhattan,
The City of New York, New York (each, a "New York Court"), (ii) waives, to the
fullest extent it may effectively do so, any objection which it may now or

sovereign immunity, immunity to pre-judgment attachment, post judgment
attachment and execution) in any legal suit, action or proceeding against it
arising out of or based on this Agreement or the transactions contemplated
hereby which is instituted in any New York Court or in any competent court in
Bermuda. The Company has appointed David Walton, who, as its authorized agent
(the "Authorized Agent") upon whom process may be served in any such suit,

transactions contemplated hereby which may be instituted in any New York Court
by the Underwriters or by any person who controls an Underwriter, expressly
consents to the jurisdiction of any such court in respect of any such suit,
action or proceeding, and waives any other requirements of or objections to
personal jurisdiction with respect thereto. Such appointments shall be
irrevocable. The Company represents and warrants that the Authorized Agent has

all action, including the filing of any and all documents and instruments that
