THE SHARES REPRESENTED BY THE CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER CONTAINED IN THE STOCKHOLDER'S AGREEMENT BY AND BETWEEN THE ISSUER AND THE ORIGINAL HOLDER HEREOF, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH RESTRICTIONS ARE BINDING ON TRANSFEREES OF THESE SHARES.

TRANSFER OF RESTRICTED SECURITIES. (A) NOTICE OF PROPOSED TRANSFERS. The holder of each certificate representing Restricted Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 4. Prior to any proposed sale, assignment, transfer or pledge of any Restricted Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transfer, the holder thereof shall give written notice to the Company of such holder's intention to effect such transfer, sale, assignment or pledge. Each such notice shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge in sufficient detail, and, if requested by the Company, the holder shall also provide, at such holder's election and expense, either (i) a written opinion of legal counsel who shall be, and whose legal opinion shall be reasonably satisfactory to the Company, addressed to the Company, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, or (ii) a "no action" letter from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the holder to the Company; provided, however, that no opinion of counsel or "no action" letter shall be required with respect to (i) a transfer not involving a change in beneficial ownership, (ii) a transaction involving the distribution without consideration of Restricted Securities by the holder to its constituent partners or members in proportion to their ownership interests in the holder, or (iii) a transaction involving the transfer without consideration of Restricted Securities by an individual holder during such holder's lifetime by way of gift or on death by will or intestacy. Each certificate evidencing the Restricted Securities transferred as above provided shall bear, except if such transfer is made pursuant to Rule 144, the appropriate restrictive legend set forth in Section 3 above, except that such certificate shall not bear such restrictive legend if in the opinion of counsel for such holder and counsel for the Company such legend is not required in order to establish compliance with any provision of the Securities Act. (B) REMOVAL OF LEGENDS. If any shares of Common Stock that were Restricted Securities become eligible for sale pursuant to Rule 144(k) or otherwise cease to be Restricted Securities, the Company shall, upon the request of the holder of such Common Stock, promptly remove the first legend set forth in Section 3 from the certificates for such Common Stock. At any time following the date that is six months after the Closing Date, the Company shall, upon the request of Investor, promptly remove the second legend set forth in Section 3 from any certificates representing shares of Common Stock. 5. TRANSFER OF RIGHTS. The rights granted to Investor or a permitted transferee hereunder may be assigned to any transferee of any shares of Common Stock, including any constituent partner or member of a holder which is a partnership or limited liability company, or to an Affiliate of a holder which is a corporation, partnership or limited liability company, provided that: (i) such transferee or assignee has acquired at least twenty percent (20%) of the Common Stock previously purchased by Investor pursuant to Investor's Investment Agreement; (ii) such transfer is effected in accordance with applicable securities laws and the terms of this Agreement; (iii) written notice is promptly given to the Company; and (iv) such transferee or assignee agrees in writing to be bound by the provisions of this Agreement; provided, further, that clause (i) in the foregoing proviso shall not apply with respect to the provisions of Section 6 hereof. 6. REGISTRATION RIGHTS. (A) COMPANY REGISTRATION. The Company shall (i) cause a shelf registration statement on Form S-3 (or other appropriate form) covering the resale of all of the Registrable Securities to be filed with the Commission within forty-five (45) days after the Closing Date, (ii) cause such registration statement to be declared effective by the Commission no later than six (6) months after the Closing Date and (iii) keep such registration statement continuously effective until Investor no longer holds any Registrable Securities that may not be sold either pursuant to (x) Rule 144(k) or (y) in their entirety in a single transaction pursuant to Rule 144.

If the Company proposes to register any of its shares of Common Stock (other than any registration for the account of the Company of securities issued pursuant to any employee benefit plan or in any acquisition by the Company), the Company will include in such registration all shares of Common Stock held by the holders of Registrable Securities requested to be so included; provided, however, that if, in the case of an underwritten offering, the managing underwriter informs the Company that the number of shares of Registrable Securities requested to be included in such offering by Investor, together with all Registrable Securities (as defined in the Other Stockholder Agreements) requested to be included in such offering by the Other Investors pursuant to the Other Stockholder Agreements (collectively, the "REQUESTED INVESTOR SHARES") exceeds the amount which can be sold in such offering without adversely affecting the distribution of the shares being offered, the Company shall include, first, all of the shares the Company has proposed to register; second, as many of the Requested Investor Shares, chosen pro rata based on the number of Requested Investor Shares, as can be included without adversely affecting such distribution; and, third, any other shares of Common Stock proposed to be included in such offering. With respect to terms and conditions not provided for in this paragraph or in this Section 6, the "piggyback" rights provided for in this paragraph are intended to be on customary terms. Notwithstanding the foregoing, this Section 6(a) shall not be applicable to (i) any registration statements filed in connection with the registration of warrants to purchase Common Stock issued by the Company on the date hereof, (ii) the Company's Registration Statement on Form S-1 (File No. 333-126226) or (iii) any registration statements filed in connection with the registration of Convertible Notes being offered by the Company as contemplated by the preliminary offering memorandum, dated September 20, 2005. (B) EXPENSES OF REGISTRATION. All Registration Expenses incurred in connection with the registration described in Section 6(a) shall be borne by the Company. All other registration expenses, if any, (i) that are not directly attributable to a single Investor shall be borne by Investor and the Other Investors pro rata on the basis of the number of shares so registered or proposed to be so registered and (ii) that are directly attributable to a single Investor shall be borne by such Investor. (C) REGISTRATION PROCEDURES. The Company will keep Investor advised in writing as to the initiation of the registration described in Section 6(a) and as to the completion thereof. The Company will: (I) Registration Statement.

Furnish to Investor such number of copies of the registration statement, any amendments thereto, any documents incorporated by reference therein, a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as Investor may reasonably request in order to facilitate the disposition of Registrable Securities owned by Investor. (IV) Qualification. Use its reasonable best efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by Investor; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act. (V) Underwriting Obligations. In the event of any underwritten public offering of Registrable Securities, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. If Investor participates in such underwriting, Investor shall also enter into and perform its obligations under such an underwriting agreement. The Company shall, if requested by the managing underwriter or underwriters, if any, counsel to Investor, or any holder of Registrable Securities included in such offering, promptly incorporate in a prospectus supplement or post-effective amendment such information as such managing underwriter or underwriters, counsel to Investor or any holder of Registrable Securities reasonably requests to be included therein, and which is reasonably related to the offering of such Registrable Securities, including, without limitation, with respect to the Registrable Securities being sold by such holder to such underwriter or underwriters, the purchase price being paid therefor by such underwriter or underwriters and any other terms of an underwritten offering of the Registrable Securities to be sold in such offering, and the Company shall promptly make all required filings of such prospectus supplement or post-effective amendment. (VI) Notice. If Investor is holding Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act, immediately notify Investor of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing (a "SUSPENSION NOTICE"); provided, however, that (i) the Company shall not give more than two Suspension Notices during any period of twelve consecutive months, (ii) any such Suspension Notice shall not be given within 120 days of the end of the Suspension Notice period under the prior Suspension Notice and (iii) in no event shall the period from the date on which any holder of Registrable Securities receives a Suspension Notice until the date on which such holder receives copies of the supplemented or amended prospectus or is advised in writing by the Company that the use of the prospectus may be resumed exceed for all Suspension Notices in the aggregate, 60 days in any 365 day period. The Company will use reasonable best efforts to promptly amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. (VII) Listing. Cause all such Registrable Securities registered pursuant hereto to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed or, if no securities are then listed, on the NASDAQ Stock Market Inc.'s National Market or on the New York Stock Exchange.

Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities not later than the effective date of such registration.

(XII) NASD Matters. Cooperate with Investor and each underwriter participating in the disposition of Registrable Securities and their respective counsel in connection with any filings required to be made with the National Association of Securities Dealers, Inc. ("NASD"), including, if appropriate, the pre-filing of a prospectus as part of a registration statement in advance of an underwritten offering. (D) INDEMNIFICATION. (I) Company Indemnification. The Company will indemnify each holder (if Registrable Securities held by such holder are included in the securities as to which such registration is being effected), each of its officers and directors and partners, and each person controlling such holder within the meaning of Section 15 of the Securities Act, with respect to which registration has been effected pursuant to this Agreement, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by the Company of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to the Company in connection with any such registration, and the Company will reimburse each such holder, each of its officers and directors, and each person controlling such holder, for any legal and any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such holder or controlling person, and stated to be specifically for use therein; provided, further, that the indemnity agreement contained in this subsection 6(d)(i) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld). (II) Investor Indemnification. Each holder will, if Registrable Securities held by such holder are included in the securities as to which such registration is being effected, indemnify the Company, each of its directors and officers, other holders of the Company's securities covered by such registration statement, each person who controls the Company within the meaning of Section 15 of the Securities Act, and each such holder, each of its officers and directors and each person controlling such holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by such holder of the Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under such laws applicable to such holder, and will reimburse the Company, each such other holder, such directors, officers, persons, underwriters or control persons for any legal or any other expenses reasonably incurred, as such expenses are incurred, in connection with investigating or defending any such claim, loss, damage, liability or action, but in the case of the Company or such other holder or their officers, directors or controlling persons, only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such holder and stated to be specifically for use therein; provided, further, that the indemnity agreement contained in this Subsection 6(d)(ii) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such indemnifying holder (which consent shall not be unreasonably withheld or delayed). The liability of any holder for indemnification under this Section 6(d) in its capacity as a seller of Registrable Securities shall not exceed the lesser of (i) that proportion of the total of such losses, claims, damages, expenses or liabilities indemnified against equal to the proportion of the total securities sold under such registration statement by such holder, and (ii) the amount equal to the net proceeds to such holder of the securities sold in any such registration. (III) Notice. Each party entitled to indemnification under this Section 6(d) (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement unless the failure to give such notice is materially prejudicial to an Indemnifying Party's ability to defend such action and provided further, that the Indemnifying Party shall not assume the defense for matters as to which there is a conflict of interest or there are separate and different defenses. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (whose consent shall not be unreasonably withheld), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (IV) Contribution. If the indemnification provided for in this Section 6(d) is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any losses, claims, damages or liabilities referred to herein, the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the untrue statement or omission that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by Investor hereunder exceed the proceeds from the offering received by Investor. (V) Survival. The obligations of the Company and Investor under this Section 6(d) shall survive completion of any offering of Registrable Securities in a registration statement and the termination of this agreement. The provisions of this Section 6(d) shall survive any termination of this Agreement. (E) INFORMATION BY INVESTOR. If Investor holds Registrable Securities included in any registration, Investor shall furnish to the Company such information regarding Investor, the Registrable Securities held by Investor and the distribution proposed by Investor as the Company may request in writing and as shall be required in connection with any registration referred to in this Agreement. (F) RULE 144 REPORTING. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Restricted Securities to the public without registration, the Company agrees to use reasonable best efforts to: (I) Public Information. Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act; (II) Filing. File with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (III) Rule 144 Statement. So long as Investor owns any Restricted Securities, furnish Investor forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after 90 days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company and other information in the possession of or reasonably obtainable by the Company as Investor may reasonably request in availing itself of any rule or regulation of the Commission allowing Investor to sell any such securities without registration. (G) DELAY FEE. If: (i) any registration statement required to be filed pursuant to Section 6(a) is not filed within the time period specified therein, (ii) a registration statement filed hereunder is not declared effective by the SEC within the time period specified in Section 6(a) or (iii) a registration statement ceases to be effective and available for resales of Registrable Securities by Investor when the Company is required to keep such registration statement effective under this Agreement, (any such failure or breach being referred to as a "REGISTRATION DEFAULT" and, for purposes of clause (i), (ii) or (iii), the date on which such Registration Default occurs, being referred to as an "EVENT DATE"), then, in addition to, and not in lieu or limitation of, any other remedies the Investors may have in law (including damages) or equity, the Company shall pay to Investor an amount, in cash ("RD FEES") (x) upon the occurrence of a Registration Default, an amount equal to $0.165 for each Registrable Security then held by Investor, and (y) if the Registration Default has not been cured by the first month anniversary following the date of the Registration Default, an amount equal to $0.165 for each Registrable Security then held by Investor, and (z) on each monthly anniversary thereafter until the Registration Default has been cured, an amount equal to $0.165 for each Registrable Security then held by Investor; provided, however, that all periods referred to in clauses (y) and (z) above shall be tolled during delays caused by the action or inaction of Investor, and the Company shall have no liability to Investor in respect of any such delay. The RD Fees payable pursuant hereto shall be payable within five (5) business days following the date of the Registration Default or the monthly anniversary thereof, as the case may be. Notwithstanding anything to the contrary contained herein, RD Fees shall not be payable under this Section 6(g) for more than one Registration Default occurring or existing at any one time. 7. ELECTION OF DIRECTOR. (I) At or prior to the effective time of the Merger (as such term is defined in Investor's Investment Agreement), the Board of Directors of the Company (as such term is defined in Investor's Investment Agreement) shall take such actions as are necessary to cause the persons indicated on Exhibit B to be elected to the Board of Directors of the Company, for an initial three-year term, at the effective time of the Merger; provided, however, that the directors nominated by each of PAR Investment Partners, L.P., ACE Aviation Holdings Inc. and Eastshore Aviation, LLC shall be appointed to the Board of Directors of the Company on the date which is two business days after the effective time of the Merger. (II) For so long as Investor, together with its Affiliates and any of their respective shareholders, partners or members, collectively, holds not less than 35% of the number of shares of Common Stock (after accounting for any reverse stock split, pro rata repurchases or similar actions by the Company) acquired by Investor pursuant to Investor's Investment Agreement (the "DESIGNATING INVESTOR THRESHOLD"), the Company agrees to nominate, at the expiration of the term of the Investor's designee, a director nominee designated by the Investor for a successive three year term and, in the event the Investor's designee resigns, dies or become incapacitated, the Company shall cause the vacancy so created to be filled by a designee of the Investor to serve the unexpired term of the director being replaced, provided that, in either such case, the director designated or nominated by the Investor meets the basic qualifications for directors, if any, contained in the Company's bylaws applicable to all directors of the Company. If the Investor, together with its Affiliates and any of their respective shareholders, partners or members, collectively, falls below the Designating Investor Threshold, its designee shall serve out his or her term, but Investor shall no longer have a right to designate a director to the Company's Board of Directors. 8. AMENDMENT. Except as otherwise provided herein, additional parties may be added to this Agreement and any provision of this Agreement may be amended or the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Investor. Any amendment or waiver effected in accordance with this Section 8 shall be binding upon Investor, any transferee thereof and the Company. So long as the Investor and/or its permitted transferees who become parties to and bound by this Agreement collectively hold not less than 10% of the number of shares of Common Stock acquired by the Investor pursuant to such Investor's Investment Agreement, the Company shall not amend or waive any provision of any Other Stockholder Agreement except with the prior written consent of Investor. 9. GOVERNING LAW. This Agreement shall be governed in all respects by the internal laws of the State of Delaware without regard to conflict of laws provisions. 10. ENTIRE AGREEMENT.
