RESTRICTED SHARE AGREEMENT
                     UNDER THE AIRCASTLE INVESTMENT LIMITED
                         2005 EQUITY AND INCENTIVE PLAN

                          [PURCHASED RESTRICTED SHARES]

          This Award Agreement (this "Restricted Share Agreement"), dated as of
_______, 2006 (the "Date of Grant"), is made by and between Aircastle Investment
Limited, a Bermuda exempted company (the "Company") and [__________] (the
"Participant"). Capitalized terms not defined herein shall have the meaning
ascribed to them in the Aircastle Investment Limited 2005 Equity and Incentive
Plan (the "Plan"). Where the context permits, references to the Company shall
include any successor to the Company.

          1. Grant of Restricted Shares. The Company hereby grants to the
Participant [________] Shares (such shares, the "Purchased Restricted Shares")
in exchange for payment by the Participant to the Company of US$[________],
subject to all of the terms and conditions of this Restricted Share Agreement
and the Plan.

          2. Restrictions.

               (a) All Purchased Restricted Shares shall be fully vested and
credited as fully paid at the time of payment in full of the amount specified in
Section 1 hereof. There will be no restrictions on sale, assignment, mortgage,
hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust
(voting or other) or other disposition of, or creation of a security interest in
or lien on, any of the Purchased Restricted Shares or any agreement or
commitment to do any of the foregoing (each a "Transfer") with respect to the
Purchased Restricted Shares, whether voluntary or involuntary, by operation of
law or otherwise, except as set forth specifically in this Restricted Share
Agreement, including (i) Section 2(b) hereof, which provides that, upon
termination of the Participant's employment, the Participant can be required to
sell the Purchased Restricted Shares to the Company, subject to certain terms
and conditions, (ii) Section 13 hereof, which provides that no Purchased
Restricted Shares shall be sold, assigned, transferred, pledged, hypothecated or
otherwise disposed of prior to the end of the Lock-Up Period except as otherwise
expressly permitted under this Restricted Share Agreement, (iii) Section 14(a)
hereof, which provides that Participant's right to participate in certain sales
is subject to specified requirements and limitations, and (iv) Section 14(b)
hereof, which provides that Participant can be compelled to participate in
certain sales.

               (b) Upon any termination of the Participant's employment with the
Company or any affiliate of the Company (unless, upon such termination,
Participant immediately becomes employed by the Company or another affiliate of
the Company) for any reason prior to the Public Offering Date (as defined in
Section 13(b) below) (a "Call Purchase Event"), subject to the provisions of
this Section 2(b), the Company may, at its option, exercisable by written notice
(a "Call Notice") delivered to the Participant (or in

                                       -1-

the case of a deceased Participant, the Participant's personal representative,
executor or administrator) within ninety (90) days after the applicable Call
Purchase Event (or, in the event the applicable Call Purchase Event is the death
of the Participant, within thirty (30) days after the appointment and
qualification of the deceased Participant's personal representative, if later),
elect to repurchase and, upon the giving of such notice, the Company shall be
obligated to repurchase and the Participant (and the related transferees, if
any, of the Participant or, in the case of a deceased Participant, his personal
representative, executor or administrator) (the "Seller") shall be obligated to
sell, all of the Restricted Purchased Shares held by the Seller at a per-Share
price equal to:

               (i)   if the Participant is terminated by the Company or an
                     affiliate for Cause, then the lower of (x) Fair Market
                     Value or (y) US$10;

               (ii)  if the Participant is terminated by the Company or an
                     affiliate without Cause, then Fair Market Value; or

               (iii) if Participant's employment with the Company or any
                     affiliate terminates for any other reason, then US$10.

"Fair Market Value" of the Shares, on a per-Share basis, shall be determined as
of the time of the Call Purchase Event by the Board in good faith and shall be
final, conclusive and binding on all persons, including the Company and the
Seller; provided, however, that such determination shall be based upon the
Company as a going concern and shall not discount the value of such shares
either because they are subject to the restrictions set forth in this Restricted
Share Agreement or because they constitute only a minority interest in the
Company.

          3. Adjustments. Pursuant to Section 5 of the Plan, in the event of a
change in capitalization as described therein, the Administrator shall make such
equitable changes or adjustments as it deems necessary or appropriate to the
number and kind of securities or other property (including cash) issued or
issuable in respect of outstanding Purchased Restricted Shares.

          4. Legend on Certificates. The Participant agrees that any certificate
issued for Purchased Restricted Shares (or, if applicable, any book entry
statement issued for Purchased Restricted Shares) prior to the lapse of any
outstanding restrictions relating thereto shall bear the following legend (in
addition to any other legend or legends required under applicable federal and
state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
     RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE (THE "RESTRICTIONS") AS
     SET FORTH IN THE AIRCASTLE INVESTMENT LIMITED 2005 EQUITY AND INCENTIVE
     PLAN AND A RESTRICTED SHARE AGREEMENT ENTERED INTO BETWEEN THE REGISTERED
     OWNER AND AIRCASTLE INVESTMENT LIMITED, COPIES OF WHICH ARE ON FILE WITH
     THE SECRETARY OF THE COMPANY. ANY ATTEMPT TO DISPOSE OF THESE SHARES IN

                                       -2-

     CONTRAVENTION OF THE RESTRICTIONS, INCLUDING BY WAY OF SALE, ASSIGNMENT,
     TRANSFER, PLEDGE, HYPOTHECATION OR OTHERWISE, SHALL BE NULL AND VOID AND
     WITHOUT EFFECT AND SHALL RESULT IN THE FORFEITURE OF SUCH SHARES AS
     PROVIDED BY SUCH PLAN AND AGREEMENT.

          5. Certain Changes. The Administrator may adjust any of the terms of
the Purchased Restricted Shares; provided that, subject to Section 5 of the
Plan, no action under this Section shall adversely affect the Participant's
rights hereunder.

          6. Notices. All notices and other communications under this Restricted
Share Agreement shall be in writing and shall be given by facsimile or first
class mail, certified or registered with return receipt requested, and shall be
deemed to have been duly given three days after mailing or 24 hours after
transmission by facsimile to the respective parties, as follows: (i) if to the
Company, c/o Aircastle Advisor LLC, 300 First Stamford Place, 5th Floor,
Stamford, CT 06902, Attn: General Counsel and (ii) if to the Participant, using
the contact information on file with the Company. Either party hereto may change
such party's address for notices by notice duly given pursuant hereto.

          7. Securities Laws Requirements. The Company shall not be obligated to
issue Shares to the Participant free of the restrictive legend described in
Section 4 hereof or of any other restrictive legend, if such transfer, in the
opinion of counsel for the Company, would violate the Securities Act of 1933, as
amended (the "Securities Act") (or any other federal or state statutes having
similar requirements as may be in effect at that time).

          8. No Obligation to Register. The Company shall be under no obligation
to register the Purchased Restricted Shares pursuant to the Securities Act or
any other federal or state securities laws.

          9. Protections Against Violations of Agreement. Any purported Transfer
of Purchased Restricted Shares or any economic benefit or interest therein in
violation of this Restricted Share Agreement shall be null and void ab initio,
and shall not create any obligation or liability of the Company, and any person
purportedly acquiring any Purchased Restricted Shares or any economic benefit or
interest therein transferred in violation of this Restricted Share Agreement
shall not be entitled to be recognized as a holder of such Shares.

          10. Taxes. The Participant understands that he or she (and not the
Company) shall be responsible for any tax liability that may arise as a result
of the transactions contemplated by this Restricted Share Agreement. The
Participant shall pay to the Company promptly upon request, and in any event at
the time the Participant recognizes taxable income in respect to the Purchased
Restricted Shares, an amount equal to the taxes the Company determines it is
required to withhold at the lowest applicable rate determined by the Company
under applicable tax laws with respect to the Purchased Restricted Shares. The
Participant may satisfy the foregoing requirement by making a payment to the
Company in cash or, with the approval of the Administrator, in its sole
discretion, by electing to have the Company repurchase Shares which the
Participant

                                       -3-

already owns and in such event the Company shall repurchase such number of
Shares having a value equal to the minimum amount of tax required to be
withheld. Such Shares shall be valued at their Fair Market Value on the date as
of which the amount of tax to be withheld is determined. Any fractional amounts
shall be settled in cash.

The Participant acknowledges that the tax laws and regulations applicable to the
Purchased Restricted Shares and the disposition of the Purchased Restricted
Shares following vesting are complex and subject to change, and it is the sole
responsibility of the Participant to obtain his or her own advice as to the tax
treatment of the terms of this Restricted Share Agreement.

     BY SIGNING THIS AGREEMENT, THE PARTICIPANT REPRESENTS THAT HE OR SHE HAS
     REVIEWED WITH HIS OR HER OWN TAX ADVISORS THE FEDERAL, STATE, LOCAL AND
     FOREIGN TAX CONSEQUENCES OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT
     AND THAT HE OR SHE IS RELYING SOLELY ON SUCH ADVISORS AND NOT ON ANY
     STATEMENTS OR REPRESENTATIONS OF THE COMPANY OR ANY OF ITS AGENTS. THE
     PARTICIPANT UNDERSTANDS AND AGREES THAT HE OR SHE (AND NOT THE COMPANY)
     SHALL BE RESPONSIBLE FOR ANY TAX LIABILITY THAT MAY ARISE AS A RESULT OF
     THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

          11. Failure to Enforce Not a Waiver. The failure of the Company to
enforce at any time any provision of this Restricted Share Agreement shall in no
way be construed to be a waiver of such provision or of any other provision
hereof.

          12. Investment Representation. The Participant hereby represents and
warrants to the Company that the Participant, by reason of the Participant's
business or financial experience (or the business or financial experience of the
Participant's professional advisors who are unaffiliated with and who are not
compensated by the Company or any affiliate or selling agent of the Company,
directly or indirectly), (a) has the capacity to protect the Participant's own
interests in connection with the transactions contemplated under this Restricted
Share Agreement and (b) is capable of evaluating the merits and risks of the
purchase of the Purchased Restricted Shares. In addition, the Participant hereby
represents and warrants that (i) he or she has an individual net worth, or a
joint net worth with his or her spouse, as of the date hereof in excess of
US$1,000,000 and (ii) he or she had an individual income in excess of US$200,000
in each of the two most recent years or join income with his or her spouse in
excess of US$300,000 in each of those years and he or she has a reasonable
expectation of reaching the same income level in the current year.

          13. Lock-Up.

               (a) The Participant agrees that, during the period specified in
Section 13(b) (the "Lock-Up Period"), he or she will not offer, sell, contract
to sell, charge, pledge, grant any option to purchase, make any short sale or
otherwise dispose of any Purchased Restricted Shares (the "Locked-Up Shares"),
except as set forth in Section

                                       -4-

13(d) hereof or Section 14(a) or 14(b) hereof. The foregoing restriction is
expressly agreed to preclude the Participant from engaging in any hedging or
other transaction which is designed to or which reasonably could be expected to
lead to or result in a sale or disposition of the Locked-Up Shares even if such
Shares would be disposed of by someone other than the Participant. Such
prohibited hedging or other transactions would include without limitation any
short sale or any purchase, sale or grant of any right (including without
limitation any put or call option) with respect to any of the Locked-Up Shares
or with respect to any security that includes, relates to, or derives any
significant part of its value from such shares.

               (b) The initial Lock-Up Period will commence on the Date of Grant
and continue for 120 days after the initial Public Offering (as defined in
Section 14(a) hereof) date set forth on the final prospectus used to sell the
Shares (the "Public Offering Date"); provided, however, that if (i) during the
last 17 days of the initial Lock-Up Period, the Company releases earnings
results or announces material news or a material event or (ii) prior to the
expiration of the initial Lock-Up Period, the Company announces that it will
release earnings results during the 15-day period following the last day of the
initial Lock-Up Period, then in each case the Lock-Up Period will be
automatically extended until the expiration of the 18-day period beginning on
the date of release of the earnings results or the announcement of the material
news or material event, as applicable, unless the initial Public Offering
underwriters each waives, in writing, such extension.

               (c) The Participant further agrees that, prior to engaging in any
transaction or taking any other action that is subject to the terms of this
Restricted Share Agreement during the period from the Date of Grant to and
including the 34th day following the expiration of the initial Lock-Up Period
(except in accordance with Section 14(a) or 14(b) hereof), it will give notice
thereof to the Company and will not consummate such transaction or take any such
action unless it has received written confirmation from the Company that the
Lock-Up Period (as such may have been extended pursuant to the previous
paragraph) has expired.

               (d) Notwithstanding the foregoing, if the Purchased Restricted
Shares are otherwise vested and transferable pursuant to this Restricted Share
Agreement, then the Participant may transfer the Locked-Up Shares (i) as a bona
fide gift or gifts, provided that the donee or donees thereof agree to be bound
in writing by the restrictions set forth herein, (ii) to any trust for the
direct or indirect benefit of the Participant or the immediate family of the
Participant, provided that the trustee of the trust agrees to be bound in
writing by the restrictions set forth herein, and provided further that any such
transfer shall not involve a disposition for value, or (iii) with the prior
written consent of the Company. For purposes of this Section 13, "immediate
family" shall mean any relationship by blood, marriage or adoption, not more
remote than first cousin. The Participant also agrees and consents to the entry
of stop transfer instructions with the Company's transfer agent and registrar
against the transfer of the Locked-Up Shares except in compliance with the
foregoing restrictions or in accordance with Section 14(a) or 14(b) hereof.

               (e) The Participant understands that the Company is relying

                                       -5-

upon the Participant's agreement in this Section 13 in proceeding toward
consummation of the initial Public Offering. The Participant further understands
that Participant's agreement in this Section 13 is irrevocable and shall be
binding upon the Participant's heirs, legal representatives, successors, and
assigns.

          14. Tag Along and Drag Along Rights.

               (a) Tag Along Rights. Prior to the initial Public Offering by the
Company, in the event that the Fortress Shareholders (as defined in this
Section) shall propose to transfer, in one or more transactions, more than 50%
of the Shares they collectively own to a third party or third parties (other
than another Fortress Shareholder) (a "Proposed Purchaser"), the Participant
shall have the right and option (the "Tag Along Right"), but not the obligation,
to participate in such sale, at the same price (which shall take into account
all consideration proposed to be paid by the Proposed Purchaser to the Fortress
Shareholders in such sale) and on the same terms and subject to the same
conditions as the sale proposed by the Fortress Shareholders, by transferring up
to the same proportion of the Purchased Restricted Shares acquired by the
Participant pursuant to this Agreement as the proportion of Fortress
Shareholders' Shares that shall be transferred in such sale. Fortress
Shareholders shall notify the Company and the Participant in writing of any such
proposed sale at least thirty (30) days prior to the proposed effective date of
such proposed sale, which notice shall specify the name and address of the
Proposed Purchaser in such sale, (ii) the proposed purchase price to be paid by
the Proposed Purchaser in such sale, (iii) the other material terms and
conditions of such proposed sale, (iv) the proposed effective date of the
proposed sale and (vi) that the Proposed Purchaser has been informed of the Tag
Along Right and has agreed to purchase the Participant's Shares. The Participant
may exercise the Tag Along Right in respect of any such sale by notifying the
Company and the Fortress Shareholders in writing within ten (10) days following
notice from the Fortress Shareholders described in the preceding sentence, but
in any event no later than fifteen (15) days prior to the proposed effective
date of such proposed sale, and, thereafter, shall be irrevocably bound to
participate in such sale on such terms and shall execute and deliver any
purchase agreement or other certificate, instrument or other agreement required
by the Proposed Purchaser to consummate the proposed sale. For purposes of this
Agreement, (i) "Fortress Shareholder" shall have the same meaning as Permitted
Transferee, and shall include the FIG Funds, as each such term is defined in the
Plan, that currently own Shares; and (ii) "Public Offering" shall mean an
offering of equity securities of the Company pursuant to an effective
registration statement under the Securities Act, including an offering in which
the Fortress Stockholders are entitled to sell Shares.

               (b) Drag Along Rights. Prior to the initial Public Offering by
the Company, in the event that the Fortress Shareholders shall propose to
transfer, in one or more transactions, more than 50% of the Shares they
collectively own to a Proposed Purchaser, the Fortress Shareholders shall have
the right and option (the "Drag Along Right"), but not the obligation, to compel
the Participant to participate in such sale, at the same price (which shall take
into account all consideration proposed to be paid by the Proposed Purchaser to
the Fortress Shareholders in such sale) and on the same terms and subject to the
same conditions as the sale proposed by the Fortress Shareholders, by

                                       -6-

transferring up to the same proportion of the Purchased Restricted Shares
acquired by the Participant pursuant to this Agreement as the proportion of the
Fortress Shareholders' Shares that shall be transferred in such sale. Fortress
Shareholders may exercise the Drag Along Right in respect of any such sale by
notifying the Company and the Participants in writing no later than fifteen (15)
days prior to the proposed effective date of such proposed sale of (i) the
proposed purchase price to be paid by the Proposed Purchaser in such sale, (ii)
the other material terms and conditions of such proposed sale and (iii) the
proposed effective date of the proposed sale. Upon receipt of such notice, the
Participant shall execute and deliver any purchase agreement or other
certificate, instrument or other agreement required by the Proposed Purchaser to
consummate the proposed sale on or prior to the proposed effective date.

          15. Governing Law. This Restricted Share Agreement shall be governed
by and construed according to the laws of Bermuda.

          16. Incorporation of Plan. The Plan is hereby incorporated by
reference and made a part hereof, and the Purchased Restricted Shares and this
Restricted Share Agreement shall be subject to all terms and conditions of the
Plan and this Restricted Share Agreement.

          17. Amendments; Construction. The Administrator may amend the terms of
this Restricted Share Agreement prospectively or retroactively at any time, but
no such amendment shall impair the rights of the Participant hereunder without
his or her consent. To the extent the terms of Section 12 above conflict with
any prior agreement between the parties related to such subject matter, the
terms of Section 12 shall supersede such conflicting terms and control. Headings
to Sections of this Restricted Share Agreement are intended for convenience of
reference only, are not part of this Restricted Share Agreement and shall have
no affect on the interpretation hereof.

          18. Survival of Terms. This Restricted Share Agreement shall apply to
and bind the Participant and the Company and their respective permitted
assignees and transferees, heirs, legatees, executors, administrators and legal
successors.

          19. Rights as a Shareholder. During the period until the restrictions
on Transfer of the Restricted Share lapse as provided in Section 2(a) hereof,
the Participant shall have all the rights of a shareholder with respect to the
Purchased Restricted Shares save only the right to Transfer the Purchased
Restricted Shares. Accordingly, the Participant shall have the right to vote the
Purchased Restricted Shares and to receive any ordinary dividends paid to or
made with respect to the Purchased Restricted Shares.

          20. Agreement Not a Contract for Services. Neither the Plan, the
granting of the Purchased Restricted Shares, this Restricted Share Agreement nor
any other action taken pursuant to the Plan shall constitute or be evidence of
any agreement or understanding, express or implied, that the Participant has a
right to continue to provide services as an officer, director, employee,
consultant or advisor of the Company or any Subsidiary or Affiliate for any
period of time or at any specific rate of compensation.

          21. Authority of the Administrator; Disputes. The Administrator shall

                                       -7-

have full authority to interpret and construe the terms of the Plan and this
Restricted Share Agreement. The determination of the Administrator as to any
such matter of interpretation or construction shall be final, binding and
conclusive.

          22. Representations. The Participant has reviewed with the
Participant's own tax advisors the Federal, state, local and foreign tax
consequences of the transactions contemplated by this Restricted Share
Agreement. The Participant is relying solely on such advisors and not on any
statements or representations of the Company or any of its agents. The
Participant understands that he or she (and not the Company) shall be
responsible for any tax liability that may arise as a result of the transactions
contemplated by this Restricted Share Agreement.

          23. Severability. Should any provision of this Restricted Share
Agreement be held by a court of competent jurisdiction to be unenforceable, or
enforceable only if modified, such holding shall not affect the validity of the
remainder of this Restricted Share Agreement, the balance of which shall
continue to be binding upon the parties hereto with any such modification (if
any) to become a part hereof and treated as though contained in this original
Restricted Share Agreement.

          24. Acceptance. The Participant hereby acknowledges receipt of a copy
of the Plan and this Restricted Share Agreement. The Participant has read and
understands the terms and provisions of the Plan and this Restricted Share
Agreement, and accepts the Purchased Restricted Shares subject to all the terms
and conditions of the Plan and this Restricted Share Agreement. The Participant
hereby agrees to accept as binding, conclusive and final all decisions or
interpretations of the Administrator upon any questions arising under this
Restricted Share Agreement.

          IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Restricted Share Agreement on the day and year first above written.

                                       -8-RESTRICTED SHARE AGREEMENT
                     UNDER THE AIRCASTLE INVESTMENT LIMITED
                         2005 EQUITY AND INCENTIVE PLAN

          This Award Agreement (this "Restricted Share Agreement"), dated as of
_______, 2006 (the "Date of Grant"), is made by and between Aircastle Investment
Limited, a Bermuda exempted Company (the "Company") and [__________] (the
"Participant"). Capitalized terms not defined herein shall have the meaning
ascribed to them in the Aircastle Investment Limited 2005 Equity and Incentive
Plan (the "Plan"). Where the context permits, references to the Company shall
include any successor to the Company.

          1. Grant of Restricted Shares. The Company hereby grants to the
Participant [________] Shares (such shares, the "Restricted Shares"), subject to
all of the terms and conditions of this Restricted Share Agreement and the Plan.

          2. Lapse of Restrictions.

               (a) Vesting.

               (i) General. Subject to the provisions set forth below, the
restrictions on Transfer (as defined in Section 9 hereof) set forth in Section
2(b) hereof shall lapse with respect to the number of Restricted Shares
specified for each Vesting Date as follows:

                      Number of
Vesting Date     Restricted Shares
--------------   -----------------
January 1, 200
January 1, 200
January 1, 200
January 1, 200
January 1, 200

subject in each case to the continued employment of the Participant by the
Company or one of its Subsidiaries or Affiliates from the date hereof through
the relevant Vesting Date, and provided that the Participant has not given
notice of resignation, as of each such Vesting Date, subject to paragraph (ii)
of this Section 2(a).

               (ii) Following Certain Terminations of Employment. Subject to the
next sentence, upon termination of the Participant's employment with the Company
and its Subsidiaries and Affiliates for any reason (including the death or
Disability of the Participant), any Restricted Shares in respect of which the
restrictions on Transfer described in this Section shall not already have lapsed
shall be immediately repurchased by the Company at a price equal to the par
value per Share and neither the Participant nor any of the Participant's
successors, heirs, assigns, or personal representatives shall

                                       -1-

thereafter have any further rights or interests in such Restricted Shares.
Notwithstanding the foregoing:

               (x) in the event that the Participant's employment with the
          Company or a Subsidiary or Affiliate is terminated without Cause, then
          the Restricted Shares (if any) which are due to vest at the next
          Vesting Date shall vest on the date of such termination of employment,
          and the restrictions on Transfer of such Restricted Shares set out in
          Section 2(b) shall lapse, subject to the Participant's execution of a
          separation agreement prepared by the Company (or any Subsidiary of
          Affiliate) which includes, inter alia, a general release of claims;
          and

               (y) in the event that the Participant's employment is terminated
          without Cause within 12 months following a Change of Control, then
          100% of the Restricted Shares that are not vested as of the date of
          such termination shall immediately vest.

               (b) Restrictions. Until the restrictions on Transfer of the
Restricted Shares lapse as provided in Section 2(a) hereof, or as otherwise
provided in the Plan, no Transfer of the Restricted Shares or any of the
Participant's rights with respect to the Restricted Shares, whether voluntary or
involuntary, by operation of law or otherwise, shall be permitted, except in
accordance with Section 14(b) hereof. Unless the Administrator determines
otherwise, upon any attempt to Transfer Restricted Shares or any rights in
respect of Restricted Shares, before the lapse of such restrictions (except in
accordance with Section 14(b) hereof), such Restricted Shares, and all of the
rights related thereto, shall be immediately repurchased by the Company at a
price equal to the par value per Share.

          3. Adjustments. Pursuant to Section 5 of the Plan, in the event of a
change in capitalization as described therein, the Administrator shall make such
equitable changes or adjustments as it deems necessary or appropriate to the
number and kind of securities or other property (including cash) issued or
issuable in respect of outstanding Restricted Shares.

          4. Legend on Certificates. The Participant agrees that any certificate
issued for Restricted Shares (or, if applicable, any book entry statement issued
for Restricted Shares) prior to the lapse of any outstanding restrictions
relating thereto shall bear the following legend (in addition to any other
legend or legends required under applicable federal and state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
     RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE (THE "RESTRICTIONS") AS
     SET FORTH IN THE AIRCASTLE INVESTMENT LIMITED 2005 EQUITY AND INCENTIVE
     PLAN AND A RESTRICTED SHARE AGREEMENT ENTERED INTO

                                       -2-

     BETWEEN THE REGISTERED OWNER AND AIRCASTLE INVESTMENT LIMITED, COPIES OF
     WHICH ARE ON FILE WITH THE SECRETARY OF THE COMPANY. ANY ATTEMPT TO DISPOSE
     OF THESE SHARES IN CONTRAVENTION OF THE RESTRICTIONS, INCLUDING BY WAY OF
     SALE, ASSIGNMENT, TRANSFER, PLEDGE, HYPOTHECATION OR OTHERWISE, SHALL BE
     NULL AND VOID AND WITHOUT EFFECT AND SHALL RESULT IN THE FORFEITURE OF SUCH
     SHARES AS PROVIDED BY SUCH PLAN AND AGREEMENT.

          5. Certain Changes. The Administrator may accelerate the date on which
the restrictions on transfer set forth in Section 2(b) hereof shall lapse or
otherwise adjust any of the terms of the Restricted Shares; provided that,
subject to Section 5 of the Plan, no action under this Section shall adversely
affect the Participant's rights hereunder.

          6. Notices. All notices and other communications under this Restricted
Share Agreement shall be in writing and shall be given by facsimile or first
class mail, certified or registered with return receipt requested, and shall be
deemed to have been duly given three days after mailing or 24 hours after
transmission by facsimile to the respective parties, as follows: (i) if to the
Company, c/o Aircastle Advisor LLC, 300 First Stamford Place, 5th Floor,
Stamford, CT 06902, Attn: General Counsel and (ii) if to the Participant, using
the contact information on file with the Company. Either party hereto may change
such party's address for notices by notice duly given pursuant hereto.

          7. Securities Laws Requirements. The Company shall not be obligated to
issue Shares to the Participant free of the restrictive legend described in
Section 4 hereof or of any other restrictive legend, if such transfer, in the
opinion of counsel for the Company, would violate the Securities Act of 1933, as
amended (the "Securities Act") (or any other federal or state statutes having
similar requirements as may be in effect at that time).

          8. No Obligation to Register. The Company shall be under no obligation
to register the Restricted Shares pursuant to the Securities Act or any other
federal or state securities laws.

          9. Protections Against Violations of Agreement. Until such time as the
Restricted Shares are fully vested in accordance with Section 2(a) hereof, no
purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge,
encumbrance, gift, transfer in trust (voting or other) or other disposition of,
or creation of a security interest in or lien on, any of the Restricted Shares
or any agreement or commitment to do any of the foregoing (each a "Transfer") by
any holder thereof in violation of the provisions of this Restricted Share
Agreement will be valid, except with the prior written consent of the Board of
Directors of the Company (such consent shall be granted or withheld in the sole
discretion of the Board of Directors) or except in accordance with Section 14(a)
or 14(b) hereof.

Any purported Transfer of Restricted Shares or any economic benefit or interest
therein in violation of this Restricted Share Agreement shall be null and void
ab initio, and shall not create any obligation or liability of the Company, and
any person purportedly acquiring

                                       -3-

any Restricted Shares or any economic benefit or interest therein transferred in
violation of this Restricted Share Agreement shall not be entitled to be
recognized as a holder of such Shares.

Without prejudice to the foregoing, in the event of a Transfer or an attempted
Transfer in violation of this Restricted Share Agreement, the Company shall have
the right (in its sole discretion) to require a repurchase from the Participant
of such Restricted Shares the subject of the Transfer or attempted Transfer at a
price per Share equal to the par value per Share.

          10. Taxes. The Participant understands that he or she (and not the
Company) shall be responsible for any tax liability that may arise as a result
of the transactions contemplated by this Restricted Share Agreement. The
Participant shall pay to the Company promptly upon request, and in any event at
the time the Participant recognizes taxable income in respect to the Restricted
Shares (or, if the Participant makes an election under Section 83(b) of the Code
in connection with such grant), an amount equal to the taxes the Company
determines it is required to withhold at the lowest applicable rate determined
by the Company under applicable tax laws with respect to the Restricted Shares.
The Participant may satisfy the foregoing requirement by making a payment to the
Company in cash or, with the approval of the Administrator, in its sole
discretion, by electing to have the Company repurchase Shares which the
Participant already owns and in such event the Company shall repurchase such
number of Shares having a value equal to the minimum amount of tax required to
be withheld. Such Shares shall be valued at their Fair Market Value on the date
as of which the amount of tax to be withheld is determined. Any fractional
amounts shall be settled in cash. The Participant shall promptly notify the
Company of any election made pursuant to Section 83(b) of the Code. A form of
such election is attached hereto as Exhibit A.

     THE PARTICIPANT ACKNOWLEDGES THAT IT IS THE PARTICIPANT'S SOLE
     RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER
     SECTION 83(b) OF THE CODE, EVEN IF THE PARTICIPANT REQUESTS THE COMPANY OR
     ITS REPRESENTATIVE TO MAKE THIS FILING ON THE PARTICIPANT'S BEHALF.

The Participant acknowledges that the tax laws and regulations applicable to the
Restricted Shares and the disposition of the Restricted Shares following vesting
are complex and subject to change, and it is the sole responsibility of the
Participant to obtain his or her own advice as to the tax treatment of the terms
of this Restricted Share Agreement.

     BY SIGNING THIS AGREEMENT, THE PARTICIPANT REPRESENTS THAT HE OR SHE HAS
     REVIEWED WITH HIS OR HER OWN TAX ADVISORS THE FEDERAL, STATE, LOCAL AND
     FOREIGN TAX CONSEQUENCES OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT
     AND THAT HE OR SHE IS RELYING SOLELY ON SUCH ADVISORS AND NOT ON ANY
     STATEMENTS OR REPRESENTATIONS OF THE COMPANY OR ANY OF ITS AGENTS. THE
     PARTICIPANT UNDERSTANDS AND AGREES

                                       -4-

     THAT HE OR SHE (AND NOT THE COMPANY) SHALL BE RESPONSIBLE FOR ANY TAX
     LIABILITY THAT MAY ARISE AS A RESULT OF THE TRANSACTIONS CONTEMPLATED BY
     THIS AGREEMENT.

          11. Failure to Enforce Not a Waiver. The failure of the Company to
enforce at any time any provision of this Restricted Share Agreement shall in no
way be construed to be a waiver of such provision or of any other provision
hereof.

          12. Confidentiality. The Participant acknowledges [and agrees to
comply with the confidentiality covenant in his employment letter dated
___________][that during the period of his employment with the Company or any
Subsidiary of Affiliate, he or she shall have access to the Company's
Confidential Information (as defined below). All books of account, records,
systems, correspondence, documents, and any and all other data, in whatever
form, concerning or containing any reference to the works and business of the
Company or its affiliated companies shall belong to the Company and shall be
given up to the Company whenever the Company requires the Participant to do so.
The Participant agrees that the Participant shall not at any time during the
term of the Participant's employment or thereafter, without the Company's prior
written consent, disclose to any person (individual or entity) any information
or any trade secrets, plans or other information or data, in whatever form,
(including, without limitation, (a) any financing strategies and practices,
pricing information and methods, training and operational procedures,
advertising, marketing, and sales information or methodologies or financial
information and (b) any Proprietary Information (as defined below)), concerning
the Company's or any of its affiliated companies' or customers' practices,
businesses, procedures, systems, plans or policies (collectively, "Confidential
Information"), nor shall the Participant utilize any such Confidential
Information in any way or communicate with or contact any such customer other
than in connection with the Participant's employment by the Company. The
Participant hereby confirms that all Confidential Information constitutes the
Company's exclusive property, and that all of the restrictions on the
Participant's activities contained in this Agreement and such other
nondisclosure policies of the Company are required for the Company's reasonable
protection. Confidential Information shall not include any information that has
otherwise been disclosed to the public not in violation of this Agreement. This
confidentiality provision shall survive the termination of this Restricted Share
Agreement and shall not be limited by any other confidentiality agreements
entered into with the Company or any of its affiliates.

With respect to any Confidential Information that constitutes a "trade secret"
pursuant to applicable law, the restrictions described above shall remain in
force for so long as the particular information remains a trade secret or for
the two year period immediately following termination of Participant's
employment for any reason, whichever is longer. With respect to any Confidential
Information that does not constitute a "trade secret" pursuant to applicable
law, the restrictions described above shall remain in force during Participant's
employment and for the two year period immediately following termination of
Participant's employment for any reason.

                                       -5-

The Participant agrees that the Participant shall promptly disclose to the
Company in writing all information and inventions generated, conceived or first
reduced to practice by him alone or in conjunction with others, during or after
working hours, while in the employ of the Company (all of which is collectively
referred to in this Agreement as "Proprietary Information"); provided, however,
that such Proprietary Information shall not include (a) any information that has
otherwise been disclosed to the public not in violation of this Agreement and
(b) general business knowledge and work skills of the Participant, even if
developed or improved by the Participant while in the employ of the Company. All
such Proprietary Information shall be the exclusive property of the Company and
is hereby assigned by the Participant to the Company. The Participant's
obligation relative to the disclosure to the Company of such Proprietary
Information anticipated in this Section shall continue beyond the Participant's
termination of employment and the Participant shall, at the Company's expense,
give the Company all assistance it reasonably requires to perfect, protect and
use its right to the Proprietary Information.

For purposes of this Section, the "Company" refers to the Company and any
incorporated or unincorporated affiliates of the Company, including any entity
which becomes the Participant's employer as a result of any reorganization or
restructuring of the Company for any reason. The Company shall be entitled, in
connection with its tax planning or other reasons, to terminate the
Participant's employment (which termination shall not be considered a
termination for any purposes of this Restricted Share Agreement, any employment
agreement or otherwise) in connection with an invitation from another affiliate
of the Company to accept employment with such affiliate in which case the terms
and conditions hereof shall apply to the Participant's employment relationship
with such entity mutatis mutandis.]

          13. Lock-Up.

               (a) The Participant agrees that, during the period specified in
Section 13(b) (the "Lock-Up Period"), he or she will not offer, sell, contract
to sell, charge, pledge, grant any option to purchase, make any short sale or
otherwise dispose of any Restricted Shares (including for all purposes of this
Section 13 Restricted Shares with respect to which all restrictions other than
those in this Section 13 have lapsed) (the "Locked-Up Shares"), except as set
forth in Section 13(d) hereof or Section 14(a) or 14(b) hereof. The foregoing
restriction is expressly agreed to preclude the Participant from engaging in any
hedging or other transaction which is designed to or which reasonably could be
expected to lead to or result in a sale or disposition of the Locked-Up Shares
even if such shares would be disposed of by someone other than the Participant.
Such prohibited hedging or other transactions would include without limitation
any short sale or any purchase, sale or grant of any right (including without
limitation any put or call option) with respect to any of the Locked-Up Shares
or with respect to any security that includes, relates to, or derives any
significant part of its value from such shares.

               (b) The initial Lock-Up Period will commence on the Date of Grant
and continue for 120 days after the initial Public Offering (as defined in
Section 14(a) hereof) date set forth on the final prospectus used to sell the
Shares (the "Public Offering Date"); provided, however, that if (i) during the
last 17 days of the initial Lock-

                                       -6-

Up Period, the Company releases earnings results or announces material news or a
material event or (ii) prior to the expiration of the initial Lock-Up Period,
the Company announces that it will release earnings results during the 15-day
period following the last day of the initial Lock-Up Period, then in each case
the Lock-Up Period will be automatically extended until the expiration of the
18-day period beginning on the date of release of the earnings results or the
announcement of the material news or material event, as applicable, unless the
initial Public Offering underwriters each waives, in writing, such extension.

               (c) The Participant further agrees that, prior to engaging in any
transaction or taking any other action that is subject to the terms of this
Restricted Share Agreement during the period from the Date of Grant to and
including the 34th day following the expiration of the initial Lock-Up Period
(except in accordance with Section 14(a) or 14(b) hereof), it will give notice
thereof to the Company and will not consummate such transaction or take any such
action unless it has received written confirmation from the Company that the
Lock-Up Period (as such may have been extended pursuant to the previous
paragraph) has expired.

               (d) Notwithstanding the foregoing, if the Restricted Shares are
otherwise vested and transferable pursuant to this Agreement, then the
Participant may transfer the Locked-Up Shares (i) as a bona fide gift or gifts,
provided that the donee or donees thereof agree to be bound in writing by the
restrictions set forth herein, (ii) to any trust for the direct or indirect
benefit of the Participant or the immediate family of the Participant, provided
that the trustee of the trust agrees to be bound in writing by the restrictions
set forth herein, and provided further that any such transfer shall not involve
a disposition for value, or (iii) with the prior written consent of the Company.
For purposes of this Section 13, "immediate family" shall mean any relationship
by blood, marriage or adoption, not more remote than first cousin. The
Participant also agrees and consents to the entry of stop transfer instructions
with the Company's transfer agent and registrar against the transfer of the
Locked-Up Shares except in compliance with the foregoing restrictions or in
accordance with Section 14(a) or 14(b) hereof.

               (e) The Participant understands that the Company is relying upon
the Participant's agreement in this Section 13 in proceeding toward consummation
of the initial Public Offering. The Participant further understands that
Participant's agreement in this Section 13 is irrevocable and shall be binding
upon the Participant's heirs, legal representatives, successors, and assigns.

          14. Tag Along and Drag Along Rights.

               (a) Tag Along Rights. Prior to the initial Public Offering by the
Company, in the event that the Fortress Shareholders (as defined in this
Section) shall propose to transfer, in one or more transactions, more than 50%
of the Shares they collectively own to a third party or third parties (other
than another Fortress Shareholder) (a "Proposed Purchaser"), the Participant
shall have the right and option (the "Tag Along Right"), but not the obligation,
to participate in such sale, at the same price (which shall take into account
all consideration proposed to be paid by the Proposed Purchaser to the

                                       -7-

Fortress Shareholders in such sale) and on the same terms and subject to the
same conditions as the sale proposed by the Fortress Shareholders, by
transferring up to the same proportion of the Restricted Shares held by the
Participant pursuant to this Agreement as to which restrictions on Transfer have
previously lapsed pursuant to Section 2(a) hereof as the proportion of Fortress
Shareholders' Shares that shall be transferred in such sale. Fortress
Shareholders shall notify the Company and the Participant in writing of any such
proposed sale at least thirty (30) days prior to the proposed effective date of
such proposed sale, which notice shall specify the name and address of the
Proposed Purchaser in such sale, (ii) the proposed purchase price to be paid by
the Proposed Purchaser in such sale, (iii) the other material terms and
conditions of such proposed sale, (iv) the proposed effective date of the
proposed sale and (vi) that the Proposed Purchaser has been informed of the Tag
Along Right and has agreed to purchase the Participant's Shares. The Participant
may exercise the Tag Along Right in respect of any such sale by notifying the
Company and the Fortress Shareholders in writing within ten (10) days following
notice from the Fortress Shareholders described in the preceding sentence, but
in any event no later than fifteen (15) days prior to the proposed effective
date of such proposed sale, and, thereafter, shall be irrevocably bound to
participate in such sale on such terms and shall execute and deliver any
purchase agreement or other certificate, instrument or other agreement required
by the Proposed Purchaser to consummate the proposed sale. For purposes of this
Agreement, (i) "Fortress Shareholder" shall have the same meaning as Permitted
Transferee, and shall include the FIG Funds, as each such term is defined in the
Plan, that currently own Shares; and (ii) "Public Offering" shall mean an
offering of equity securities of the Company pursuant to an effective
registration statement under the Securities Act, including an offering in which
the Fortress Stockholders are entitled to sell Shares.

               (b) Drag Along Rights. Prior to the initial Public Offering by
the Company, in the event that the Fortress Shareholders shall propose to
transfer, in one or more transactions, more than 50% of the Shares they
collectively own to a Proposed Purchaser, the Fortress Shareholders shall have
the right and option (the "Drag Along Right"), but not the obligation, to compel
the Participant to participate in such sale, at the same price (which shall take
into account all consideration proposed to be paid by the Proposed Purchaser to
the Fortress Shareholders in such sale) and on the same terms and subject to the
same conditions as the sale proposed by the Fortress Shareholders, by
transferring up to the same proportion of the Restricted Shares held by the
Participant pursuant to this Agreement (whether or not the restrictions on
Transfer have previously lapsed) as the proportion of the Fortress Shareholders'
Shares that shall be transferred in such sale. Notwithstanding any other
provision of this Agreement, any otherwise applicable restrictions on Transfer
shall not apply to a Transfer pursuant to this Section 14(b) and, after the
consummation of such Transfer, shall not apply to such formerly Restricted
Shares in the hands of the Proposed Purchaser or the Proposed Purchaser's
successors. Fortress Shareholders may exercise the Drag Along Right in respect
of any such sale by notifying the Company and the Participants in writing no
later than fifteen (15) days prior to the proposed effective date of such
proposed sale of (i) the proposed purchase price to be paid by the Proposed
Purchaser in such sale, (ii) the other material terms and conditions of such
proposed sale and (iii) the proposed effective date of the proposed sale. Upon
receipt of such notice, the Participant shall execute and deliver any

                                       -8-

purchase agreement or other certificate, instrument or other agreement required
by the Proposed Purchaser to consummate the proposed sale on or prior to the
proposed effective date.

          15. Governing Law. This Restricted Share Agreement shall be governed
by and construed according to the laws of Bermuda.

          16. Incorporation of Plan. The Plan is hereby incorporated by
reference and made a part hereof, and the Restricted Shares and this Restricted
Share Agreement shall be subject to all terms and conditions of the Plan and
this Restricted Share Agreement.

          17. Amendments; Construction. The Administrator may amend the terms of
this Restricted Share Agreement prospectively or retroactively at any time, but
no such amendment shall impair the rights of the Participant hereunder without
his or her consent. To the extent the terms of Section 12 above conflict with
any prior agreement between the parties related to such subject matter, the
terms of Section 12 shall supersede such conflicting terms and control. Headings
to Sections of this Restricted Share Agreement are intended for convenience of
reference only, are not part of this Restricted Share Agreement and shall have
no affect on the interpretation hereof.

          18. Survival of Terms. This Restricted Share Agreement shall apply to
and bind the Participant and the Company and their respective permitted
assignees and transferees, heirs, legatees, executors, administrators and legal
successors.

          19. Rights as a Shareholder. During the period until the restrictions
on Transfer of the Restricted Share lapse as provided in Section 2(a) hereof,
the Participant shall have all the rights of a shareholder with respect to the
Restricted Shares save only the right to Transfer the Restricted Shares.
Accordingly, the Participant shall have the right to vote the Restricted Shares
and to receive any ordinary dividends paid to or made with respect to the
Restricted Shares.

          20. Agreement Not a Contract for Services. Neither the Plan, the
granting of the Restricted Shares, this Restricted Share Agreement nor any other
action taken pursuant to the Plan shall constitute or be evidence of any
agreement or understanding, express or implied, that the Participant has a right
to continue to provide services as an officer, director, employee, consultant or
advisor of the Company or any Subsidiary or Affiliate for any period of time or
at any specific rate of compensation.

          21. Authority of the Administrator; Disputes. The Administrator shall
have full authority to interpret and construe the terms of the Plan and this
Restricted Share Agreement. The determination of the Administrator as to any
such matter of interpretation or construction shall be final, binding and
conclusive.

          22. Representations. The Participant has reviewed with the
Participant's own tax advisors the Federal, state, local and foreign tax
consequences of the transactions contemplated by this Restricted Share
Agreement. The Participant is relying solely on such advisors and not on any
statements or representations of the Company or

                                       -9-

any of its agents. The Participant understands that he or she (and not the
Company) shall be responsible for any tax liability that may arise as a result
of the transactions contemplated by this Restricted Share Agreement.

          23. Severability. Should any provision of this Restricted Share
Agreement be held by a court of competent jurisdiction to be unenforceable, or
enforceable only if modified, such holding shall not affect the validity of the
remainder of this Restricted Share Agreement, the balance of which shall
continue to be binding upon the parties hereto with any such modification (if
any) to become a part hereof and treated as though contained in this original
Restricted Share Agreement.

          24. Acceptance. The Participant hereby acknowledges receipt of a copy
of the Plan and this Restricted Share Agreement. The Participant has read and
understands the terms and provisions of the Plan and this Restricted Share
Agreement, and accepts the Restricted Shares subject to all the terms and
conditions of the Plan and this Restricted Share Agreement. The Participant
hereby agrees to accept as binding, conclusive and final all decisions or
interpretations of the Administrator upon any questions arising under this
Restricted Share Agreement.

          IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Restricted Share Agreement on the day and year first above written.
