Employees and Directors may become Participants in the Plan by completing and
filing with the Corporation a Purchase Agreement indicating their intention to
purchase Shares during the Offering Period. No Employee or Director will be

participate in or purchase Shares during any subsequent Offering Period.

SECTION 4. OFFERINGS AND PURCHASE OF SHARES

                a.         Offerings. The Board, in its sole discretion, will determine
the time or times that an Offering will be made to Employees and Directors. It
is anticipated that an Offering will be scheduled whenever the Corporation makes
a stock offering to existing shareholders. However, the Board may determine, in
its sole discretion and at any time, that an Offering will not be made,
regardless of any stock offering made to or scheduled to be made to existing
shareholders.

                b.         Offering Periods. For each Offering, the Board, in its
discretion, will determine, schedule and announce to all Employees and Directors
the beginning date and duration of each Offering Period and the maximum number
of Shares each Participant will be entitled to purchase during the Offering
Period. 

                c.         Number of Shares. The maximum number of Shares available for
purchase by a Participant during any Offering Period will be the same for all
Participants. 

                d.         Purchase of Shares.

-2-

                            i.         During each Offering Period, a Participant must complete and file a
Purchase Agreement with the Corporation indicating the specific number of Shares
the Participant wishes to purchase. The Purchase Agreement must be accompanied
by payment in full in cash or cash equivalents.

                            ii.         The purchase price of all Shares will be the Fair Market Value of
the Shares on the date of purchase.

                e.         Restrictions on Transfer. Shares offered for purchase under
the Plan may be purchased only by eligible Employees and Directors. The right to
purchase Shares in an Offering may not be sold, assigned, transferred, pledged
or otherwise encumbered. 

                f.         Delivery of Certificates. As soon as practicable after the
date of purchase of any Shares, the Corporation will have certificates
evidencing the Shares issued in the name of, and delivered to, the Participant.

SECTION 5. STOCK SUBJECT TO PLAN

                a.         Basic Limitation. The aggregate number of Shares that may be
issued under the Plan for purchase by Participants may not exceed 200,000
Shares. Shares offered under the Plan may be authorized but unissued Shares or
Treasury Shares.

                b.         Additional Shares. Any Shares that are offered to but not
purchased by Participants during any Offering Period again will be available for
purposes of the Plan.

SECTION 6. CONDITIONS TO OFFERINGS

                a.         Securities Law Requirements. No Offering may be made and no
Shares may be purchased or delivered under the Plan unless the Offering,
purchase or delivery of these Shares complies with (or is exempt from) all
applicable requirements of law, including (without limitation) the United States
Securities Act of 1933, as amended, the rules and regulations promulgated under
it, state securities laws and regulations, and the regulations of any stock
exchange or securities market on which the Corporation's securities then may be
traded. 

                b.         Inability to Obtain Authority. The inability of the
Corporation to obtain authority from any regulatory body having jurisdiction,
which authority is deemed by the Corporation's counsel to be necessary to the
lawful delivery of any Shares under this Plan, will relieve the Bank and the
Corporation of any liability in respect of the failure to sell, issue or deliver
those Shares as to which the requisite authority has not been obtained.

SECTION 7. ADMINISTRATION

                a.         Committees and Delegation of Powers.
The Plan may be administered by one or more Committees appointed by the Board. A
Committee will have the authority and be responsible for those functions
assigned to it by the Board. If no Committee is appointed, the 

-3-

entire Board will administer the Plan. Any reference to the Board in the Plan
will be construed as a reference to the Committee, if any, to which the Board
assigns a particular function in connection with the Plan. 

                b.         Powers of the Board. Subject to the provisions of the Plan,
the Board has the power to:

                            i.         Determine the time at which each Offering will be made, the
duration of each Offering Period, and the maximum number of Shares subject to
each Offering;

                            ii.         Prescribe, amend, or rescind any rules and regulations necessary
or appropriate for the administration of the Plan; 

                            iii.        Correct any defect, supply any deficiency, and reconcile any
inconsistency in the Plan or in any related agreement; and

                            iv.        Make other determinations and take such other action in connection
with the administration of the Plan as it deems necessary or advisable. 

                c.         Delegation of Duties. The Board may direct appropriate
officers of the Bank or the Corporation to implement its rules, regulations and
determinations and to execute and deliver on behalf of the Bank and the
Corporation such documents, forms, agreements and other instruments as are
deemed by the Board to be necessary for the administration and implementation of
the Plan.

                d.         Interpretation of Plan. The Board has the power in its sole
discretion to interpret and construe the Plan and all related agreements. All
decisions, interpretations and determinations of the Board with respect to the
Plan will be final and binding on all Participants and all persons deriving
their rights from Participants.

                e.         Indemnification. Each member of the Board or Committee is
indemnified and held harmless by the Corporation against any cost or expense
(including any sum paid in settlement of a claim with the approval of the
Corporation) arising out of any act or omission to act in connection with the
Plan to the extent permitted by applicable law. This indemnification is in
addition to any rights of indemnification a Board or Committee member may have
as a director or otherwise under the by-laws of the Corporation or the Bank, any
agreement, any vote of shareholders or disinterested directors, or otherwise.

SECTION 8. GENERAL

                a.         No Retention Rights. Nothing in the Plan or in any Offering
made under the Plan will confer on an Employee any right to continue in
employment for any period of time or will interfere with or otherwise restrict
in any way the rights of the Bank, the Corporation or the Employee, which rights
are expressly reserved by each, to terminate an Employee's employment at any
time and for any reason.

-4-

                b.         No Participation Rights. Nothing in the Plan or in any
Offering made under the Plan will confer on an Employee or Director any right to
receive additional Shares, to participate in or continue to participate in the
Plan following termination of Service, or to be entitled to compensation or
damages in lieu of participation or continued participation in the Plan.

                c.         Rights as a Stockholder. An Employee or Director will have
no rights as a stockholder with respect to any Shares offered for purchase in an
Offering until the date a stock certificate is issued to the Participant for the
Shares.

                d.         No Representation or Warranty. The Corporation and the Bank
make no representation or warranty as to the future market value of any Shares
purchased under the Plan. 

                e.         Plan Terms Control. In the event there is a discrepancy
between the terms of the Plan and the terms of any agreement issued under the
Plan, the terms of the Plan will control.

                f.         Effective Date. The effective date of the Plan is May 25,
2004.

SECTION 9. AMENDMENT AND TERMINATION

                a.         Right to Amend or Terminate the Plan. The Board may amend,
suspend or terminate the Plan at any time and for any reason.

                b.         Effect of Amendment or Termination. No amendment,
suspension, or termination of the Plan will, without the consent of the affected
Participant, alter or impair any rights or obligations under any Offering
previously made under the Plan, unless the amendment, suspension or termination
is required by applicable law.

SECTION 10. APPLICABLE LAW

                The Plan and all Offerings made under it will be construed and interpreted in
accordance with, and governed by, the laws of New York, other than its laws
regarding choice of law.

                To record the adoption of the Plan by the Board, the Corporation has caused
its authorized officer to execute it.

                           STOCK PURCHASE AGREEMENT

          THIS AGREEMENT (including all exhibits and schedules) (the
"Agreement") is made as of June 11, 2004, by and between RC Aviation LLC, a

owns directly and indirectly all of the issued and outstanding capital stock
of Hawaiian Airlines, Inc., a Hawaii corporation ("HAL").

          WHEREAS, HAL is a debtor in a case (the "Bankruptcy Case") filed in
the United States Bankruptcy Court for the District of Hawaii (the "Bankruptcy

replacement trustee (the "Trustee").

          WHEREAS, HHI has not filed, and has not had filed against it, a
petition for reorganization, or any other form relief under the Bankruptcy
Code, and, therefore, continues to operate outside of the jurisdiction of the
Bankruptcy Court.

          WHEREAS, subject to the terms and conditions set forth herein, Buyer
desires to acquire from Seller, Ten Million shares of the Common Stock (the

<PAGE>

the Seller to believe that the information contained therein is untrue,
incorrect or false or misleading in any material respect.

under the circumstances.

Section 8.2 shall be asserted and resolved as follows:

                    (i) Notice of Claims. In the event that (A) any claim,
               demand or action is asserted or instituted by any Person other
               than the parties to this Agreement or which could give rise to
               Damages for which an Indemnifying Party could be liable to an
               Indemnified Party under this Agreement (such claim, demand or
               Proceeding, a "Third Party Claim") or (B) any Indemnified Party
               under this Agreement shall have a claim to be indemnified by
               any Indemnifying Party under this Agreement which does not
               involve a Third Party Claim (such claim, a "Direct Claim" and,
               together with Third Party Claims, "Claims"), the Indemnified
               Party shall with reasonable promptness send to the Indemnifying
               Party a written notice specifying the nature of such Claim (a
               "Claim Notice"), provided that a delay in notifying the
               Indemnifying Party shall not relieve the Indemnifying Party of
               its obligations under this Agreement except to the extent that
               (and only to the extent that) the Indemnifying Party
               demonstrates such failure shall have caused the Damages for
               which the Indemnifying Party is obligated to be greater than
               such Damages would have been had the Indemnified Party given
               the Indemnifying Party timely notice.

<PAGE>

                    (ii) Third Party Claims. In the event of a Third Party
               Claim, the Indemnifying Party shall be entitled to appoint
               counsel of the Indemnifying Party's choice at the expense of
               the Indemnifying Party to represent the Indemnified Party and
               any others the Indemnifying Party may reasonably designate in
               connection with such claim, demand or Proceeding (in which case
               the Indemnifying Party shall not thereafter be responsible for
               the fees and expenses of any separate counsel retained by any
               Indemnified Party except as set forth below); provided, that
               the Indemnifying Party shall accept the defense thereof and
               acknowledge without qualifications its indemnification
               obligations as provided in this Article 8 if such defense is
               unsuccessful; provided further, that such counsel is reasonably
               acceptable to the Indemnified Party, which approval shall not
               be unreasonably withheld or delayed. Notwithstanding an
               Indemnifying Party's election to appoint counsel to represent
               an Indemnified Party in connection with a Third Party Claim, an
               Indemnified Party shall have the right to employ one separate
               counsel, and the Indemnifying Party shall bear the reasonable
               fees, costs and expenses of such separate counsel if (i) the
               Indemnifying Party is also party to such proceeding and the
               Indemnified Party determines in good faith and upon the advice
               of outside counsel that such joint representation would present
               a conflict of interest, (ii) the Indemnifying Party shall not
               have employed counsel to represent the Indemnified Party within
               a reasonable time (but no later than thirty (30) days) after
               notice of the institution of such Third Party Claim or (iii) if
               the Claim seeks injunctive relief which, if granted could
               materially and adversely affect the Indemnified Party. If
               requested by the Indemnifying Party, the Indemnified Party
               agrees to cooperate with the Indemnifying Party and its counsel
               in contesting any claim, demand or Proceeding which the
               Indemnifying Party defends, or, if appropriate and related to
               the claim, demand or Proceeding in question, in making any
               counterclaim against the person asserting the Third Party
               Claim, or any cross-complaint against any person. In the event
               the Indemnifying Party fails to assume the defense of such
               Claim within thirty (30) days after receipt of notice thereof,
               (i) the Indemnified Party against which such Claim has been
               asserted shall have the right to undertake the defense,
               compromise or settlement of such Claim on behalf of, at the
               expense of and for the account and risk of the Indemnifying
               Party, and (ii) the Indemnifying Party agrees to cooperate with
               the Indemnified Party in such defense and make available to the
               Indemnified Party, all witnesses, records, materials and
               Information in the Indemnifying Party's possession or under the
               Indemnifying Party's control relating thereto as may be
               reasonably requested by the Indemnified Party.

                    (iii) Settlement of Claims. Neither the Indemnifying Party
               nor the Indemnified Party shall, without the written consent of
               the other party (which consent shall not be unreasonably
               withheld), (A) settle or compromise any Claims or consent to
               the entry of any judgment which does not include as an
               unconditional term thereof the delivery by the claimant or
               plaintiff to the Indemnified Party or the Indemnifying Party,
               as applicable, of a written release from all liability in
               respect of such Claim of all Indemnified Parties affected by
               such Claim or (B) settle or compromise any Claim if the
               settlement imposes equitable remedies or material obligations
               on the Indemnified Party or the

                                      14
<PAGE>

               Indemnifying Party, as applicable, other than financial
               obligations for which such Indemnified Party or Indemnifying
               Party, as applicable, will be indemnified hereunder. No Claim
               which is being defended in good faith by the Indemnifying Party
               or the Indemnified Party, as applicable, in accordance with the
               terms of this Agreement shall be settled or compromised by the
               Indemnifying Party or the Indemnified Party, as applicable,
               without the written consent of the other party (which consent
               shall not be unreasonably withheld or delayed).

          (f) Access. From and after the delivery of a Claim Notice under this
Agreement, at the reasonable request of the Indemnifying Party, each
Indemnified Party shall grant the Indemnifying Party and its Representatives
all reasonable access to the books, records and properties of such Indemnified
Party to the extent reasonably related to the matters to which the Claim
Notice relates. All such access shall be granted during normal business hours
and shall be granted under conditions that will not unreasonably interfere
with the business and operations of such Indemnified Party. The Indemnifying
Party will not, and shall require that its Representatives do not, use (except
in connection with such Claim Notice) or disclose to any third person other
than the Indemnifying Party's Representatives (except as may be required by
Applicable Law) any Information obtained pursuant to this Section 8.2(f) which
is designated as confidential by an Indemnified Party.

unreasonably withheld.

          10.5 Severability

          Any term or provision of this Agreement that is invalid or
unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid
or unenforceable, the parties hereto agree that the court making the
determination of invalidity or unenforceability shall have the power to reduce
the scope, duration or area of the term or provision, to delete specific words
or phrases or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to

                                      21
<PAGE>

unenforceable term or provision, and this Agreement shall be enforceable as
so modified after the expiration of the time within which the judgment may be
appealed.

          10.6 No Strict Construction

          The language used in this Agreement shall be deemed to be the

          10.7 Amendment and Waiver

          Any provision of this Agreement or the Disclosure Letter or the
Exhibits or Schedules attached hereto may be amended or waived only in writing
signed by Buyer and Seller. No waiver of any provision hereunder or any breach
or default thereof shall extend to or affect in any way any other provision or
prior or subsequent breach or default.

          10.8 Complete Agreement

          This Agreement and the documents referred to herein (including the
Stockholders Agreement and the Registration Rights Agreement and the
Confidentiality Agreement) contain the complete agreement between the parties
hereto and supersede any prior understandings, agreements or representations
by or between the parties, written or oral, which may have related to the
subject matter hereof in any way.

          10.9 Counterparts

          This Agreement may be executed in multiple counterparts, any one of
which need not contain the signatures of more than one party, but all such

          All matters relating to the interpretation, construction, validity
and enforcement of this Agreement shall be governed by and construed in
accordance with the domestic laws of the State of Delaware without giving
effect to any choice or conflict of law provision or rule (whether of the
State of Delaware or any other jurisdiction) that would cause the application
of laws of any jurisdiction other than the State of Delaware.

          10.11 Submission to Jurisdiction

          All actions or proceedings arising in connection with this Agreement
may be tried and litigated in the state or federal courts located in the State
of Delaware. Each party hereby waives any right it may have to assert the
doctrine of forum non conveniens or similar doctrine or to object to venue
with respect to any proceeding brought in accordance with this paragraph, and
stipulates that the state and federal courts located in the State of Delaware
shall have in persona jurisdiction over each of them for the purpose of
litigating any such dispute, controversy, or proceeding. Each party hereby
authorizes and accepts service of process sufficient for personal jurisdiction
in any action against it as contemplated by this Section 10.11 by registered
or

                                      22
<PAGE>

certified mail, return receipt requested, postage prepaid, to its address
for the giving of notices as set forth in Section 10.3 above. Nothing herein
shall affect the right of any party to serve process in any other manner
permitted by law.

          10.12 Descriptive Headings; Interpretation

          The descriptive headings of this Agreement are inserted for
convenience only and do not constitute a part hereof or define, limit or
otherwise affect the meaning of any of the terms or provisions hereof. The use
of the word "including" in this Agreement shall be by way of example rather
than by limitation and shall be deemed to include the phrase "including
without limitation."

          Unless the context of this Agreement otherwise requires, (i) words
of any gender include each other gender; (ii) unless the context requires

or singular number, respectively; (iii) the terms "hereof," "herein," "hereby"
and derivative or similar words refer to this entire Agreement; and (iv) the

Agreement. Whenever this Agreement refers to a number of days, such number
shall refer to calendar days unless business days are specified. All
accounting terms used herein and not expressly defined herein shall have the
meanings given to them under GAAP.

          10.14 No Third Party Beneficiaries

Person other than the parties hereto and their respective heirs, personal
legal representatives, successors and permitted assigns, the Buyer Indemnified
Parties and the Seller Indemnified Parties.

          10.15 Delivery by Facsimile

          This Agreement and any signed agreement entered into in connection
herewith or contemplated hereby, and any amendments hereto or thereto, to the
extent signed and delivered by means of a facsimile machine, shall be treated
in all manner and respects as an original signed agreement and shall be
considered to have the same binding legal effects as if it were the original
signed version thereof delivered in person. At the request of any party hereto
or to any such agreement, each other party hereto or thereto shall re-execute
original forms thereof and deliver them to all other parties. No party hereto
or to any such agreement shall raise the use of a facsimile machine to deliver
a signature or the fact that any signature or agreement was transmitted or
communicated through the use of a facsimile machine as a defense to the
formation of an agreement and each such party forever waives any such defense.
