On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to 1,476,378 Additional Shares at the Purchase Price, subject to the conditions specified in this paragraph.

It is understood, however, that except as provided in this Section, Section 8 entitled “Indemnity and Contribution”, and the last paragraph of Section 10 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make.

7. Covenants of the Underwriters. The Underwriters covenant with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of the Underwriters that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriters. The Underwriters acknowledge and agree that, except as may be set forth in Schedule II hereto, the Company has not authorized or approved any “issuer information” (as defined in Rule 433(h)) for use in any free writing prospectus prepared by or on behalf of the Underwriters.

8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act or the Prospectus (if used within the period set forth in paragraph (c) of Section 6 hereof and as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by 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, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use in the Registration Statement, the preliminary prospectus, the Time of Sale Prospectus, any other free writing prospectus that the Company has filed or is required to file pursuant to Rule 433(d) of the Securities Act or the Prospectus or any amendment or supplement thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person

(the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, in the case of parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 8(a), 8(b) or 8(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and

distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

9. Termination. The Underwriters may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Prospectus.

10. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of

Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on the Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on the Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

12. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

13. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

14. Nature of Underwriter’s Obligations. The Company acknowledges that in connection with the offering of the Shares: (a) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (b) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (c) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

15. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company, on the one hand, and the Underwriters, on the other, with respect to the preparation of the preliminary prospectus, the Time of Sale Prospectus, the Prospectus, and the conduct of the offering, and the purchase and sale of the Shares.

16. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to you in care of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Equity Syndicate Desk, with a copy to the Legal Department; and if to the Company shall be delivered, mailed or sent to ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇.

The opinion of ▇▇▇▇▇, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLP to be delivered pursuant to Section 5(c) of the Underwriting Agreement, shall be rendered to the Underwriters at the request of the Company and shall so state therein. Such opinion shall be to the effect that:

A. The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Nevada, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus.

B. AirTran Airways, Inc. has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Delaware, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus.

G. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

H. The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Underwriting Agreement will not contravene any provision of applicable law or the articles of incorporation or by-laws of the Company or, to the best of such counsel’s knowledge, any

agreement or other instrument binding upon the Company or any of its subsidiaries that is material to the Company and its subsidiaries, taken as a whole, or, to the best of such counsel’s knowledge, any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company or any subsidiary, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under the Underwriting Agreement, except such as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Shares.

With respect to matters referred to in this paragraph, such counsel’s beliefs may be based solely upon such counsel’s participation in the preparation of the Registration Statement, the Time of Sale Prospectus and Prospectus and review and discussion of the contents thereof and review of the documents incorporated by reference therein, but are without independent check or verification.

EXHIBIT A-2

OPINION OF SENIOR VICE PRESIDENT AND GENERAL COUNSEL

FOR THE COMPANY

The opinion of the Senior Vice President and General Counsel for the Company, to be delivered pursuant to Section 5(c) of the Underwriting Agreement, shall be rendered to the Underwriters at the request of the Company and shall so state therein. Such opinion shall be to the effect that:

A. The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except where the Company has advised us that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

B. Each subsidiary of the Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole; all of the issued shares of capital stock of each subsidiary of the Company have been duly and validly authorized and issued, are fully paid and non-assessable, and are owned directly by the Company, free and clear of all liens, encumbrances, equities or claims.

C. The execution and delivery by the Company of its obligations under the Underwriting Agreement will not contravene any provision of applicable law of the State of Nevada or New York or of applicable federal law of the United States or, to the best of such counsel’s knowledge, any agreement or other instrument binding upon the Company or any of its subsidiaries that is material to the Company and its subsidiaries, taken as a whole, or, to the best of such counsel’s knowledge, any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company or any subsidiary, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under the Underwriting Agreement, except such as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Shares.

D. Such counsel does not know of any legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject other than proceedings fairly summarized in all material respects in the Time of Sale Prospectus and proceedings which such counsel believes are not likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, or on the power or ability of the Company to perform its obligations under the Underwriting Agreement or as contemplated by the Time of Sale Prospectus.

E. The Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies, including the Department of Transportation and the Federal Aviation Administration, necessary to conduct the business now operated by it and its subsidiaries, except where the failure so to comply would not, singly or in the aggregate, have a material adverse effect on the Company; (ii) the Company and its subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, have a material adverse effect on the Company; (iii) all of the Government Licenses are valid and in full force, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not have a material adverse effect on the Company; and (iv) the Company and its subsidiaries have not received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, is reasonably likely to have a material adverse effect on the Company.

F. AirTran Airways, Inc. (i) is an “air carrier” within the meaning of 49 U.S.C. Section 40102(a); (ii) holds an air carrier operating certificate issued by the Secretary of Transportation pursuant to Chapter 447 of Title 49 of the United States Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo; and (iii) is a “citizen of the United States” as defined in 49 U.S.C. Section 401102.

G. The statements relating to legal matters, documents or proceedings included in the Prospectus, in “Item 3 - Legal Proceedings” of the Company’s most recent annual report on Form 10-K, in Part II “Item 1 - Legal Proceedings” of any quarterly report on Form 10-Q and in “Item 5 - Other Events” of any current report on Form 8-K included or incorporated by reference in the Registration Statement or the Prospectus, fairly summarize in all material respects such matters or proceedings.

OPINION OF ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP

The opinion of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP to be delivered pursuant to Section 5(d) of the Underwriting Agreement shall be to the effect that:

A. The statements relating to legal matters included in the Prospectus under the caption “Underwriting” fairly summarize in all material respects such matters.

B. Nothing has come to the attention of such counsel that causes such counsel to believe that (i) each document, if any, filed or to be filed pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus (except for the financial statements and financial schedules and other financial and statistical data included therein, as to which such counsel need not express any belief) did not comply as to form when filed in all material respects with the requirements of the Exchange Act and the applicable rules and regulations of the Securities and Exchange Commission thereunder, (ii) the Registration Statement, as supplemented by the Prospectus Supplement (except as to financial statements or other financial and statistical data of the Company included therein, or omitted therefrom, as to which such counsel need not express any belief), on the date of the Underwriting Agreement contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) each of the Time of Sale Prospectus and the Prospectus (except as to financial statements or other financial and statistical data of the Company included therein, or omitted therefrom, as to which such counsel need not express any belief) on the date of the Underwriting Agreement or on the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

With respect to the matters referred to in the paragraph above, ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP may state that their beliefs are based upon their participation in the preparation of the Registration Statement, the Time of Sale Prospectus and Prospectus and any amendments or supplements thereto and documents incorporated therein by reference and review and discussion of the contents thereof, but are without independent check or verification, except as specified. With respect to clauses (i), (ii) and (iii) of the paragraph above, ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP may state that their beliefs are based upon their participation in the preparation of the Registration Statement, Time of Sale Prospectus and Prospectus and any amendments or supplements thereto (other than the

documents incorporated by reference) and upon review and discussion of the contents thereof (including documents incorporated by reference), but are without independent check or verification, except as specified.

▇▇▇▇ ▇▇▇▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Dear Sirs and Mesdames:

The undersigned understands that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”) proposes to enter into two Underwriting Agreements (the “Underwriting Agreements”) with AirTran Holdings, Inc., a Nevada corporation (the “Company”), providing for the public offering (the “Equity Public Offerings”) by the several Underwriters, including ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated (the “Underwriters”), of shares (the “Shares”) of the Common Stock, par value $0.001, (the “Common Stock”), and a concurrent public offering (the “Debt Public Offering”, and together with the Equity Public Offering, the “Public Offerings”) of Senior Convertible Notes (the “Notes”), of the Company. Neither of the Public Offerings is conditioned on the other, and this Lock-Up Agreement shall continue in effect if either Public Offering proceeds.

To induce the Underwriters that may participate in the Public Offerings to continue their efforts in connection with the Public Offerings, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus relating to the Equity Public Offering or Debt Public Offering, as applicable (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) the

sale of any Shares to the Underwriters pursuant to the applicable Underwriting Agreement, (b) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the applicable Public Offering, (c) the issuance by the Company of Common Stock upon the exercise of an option outstanding on the date hereof under the Company’s stock option plans, (d) bona fide gifts or transfers by will or intestate succession of Common Stock or any security convertible into or exercisable for Common Stock or distributions of Common Stock to limited partners, members or shareholders of the undersigned or (e) transactions pursuant to the Company’s existing Rule 10b5-1 trading programs, provided that, in the case of (c) or (d), any such donee or transferee agrees to be bound by the provisions of this Lock-Up Agreement. In addition, the undersigned agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 90 days after the date of the Prospectus relating to the Equity Public Offering or the Debt Public Offering, as applicable, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Equity Public Offering or the Debt Public Offering, as applicable. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Equity Public Offering or the Debt Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters. If for any reason the Underwriting Agreement related to the Equity Public Offering or Debt Public Offering, as applicable, is terminated prior to the closing of such Public Offering, this Lock-Up Agreement shall likewise be terminated with respect to such Public Offering.

Very truly yours,
