REGISTRATION RIGHTS AGREEMENT

This Registration Rights Agreement (this “Agreement”) is made as of April 6, 2021, by and among Frontier Group Holdings, Inc., a Delaware corporation (the “Company”), Indigo Frontier Holdings Company, LLC, a Delaware limited liability company (the “Sponsor”), and such other persons, if any, that from time to time become parties hereto pursuant to the terms hereof or who join this Agreement pursuant to a Joinder Agreement substantially in the form of Exhibit A (together, with the Sponsor, the “Stockholders”). This agreement shall become effective immediately prior to the consummation of the Initial Public Offering (such date, the “Effective Date”). Unless otherwise noted herein, capitalized terms used herein shall have the meanings set forth in Section 5.

RECITALS

A. Pursuant to that certain Subscription Agreement, dated as of December 3, 2013, by and between the Company, formerly known as Falcon Acquisition Group, Inc., a Delaware corporation, and the Sponsor, the Sponsor previously acquired 5,200,000 shares of Common Stock, par value $0.001 per share (as adjusted for any stock splits, stock dividends, reclassifications, reorganizations or similar transactions since December 3, 2013, the “Shares”), of the Company (the “Subscription Agreement”).

B. As partial consideration for the investment by the Sponsor, pursuant to Section 5.1 of the Subscription Agreement, the Company agreed upon the request of the Sponsor to enter into a registration rights agreement with the Sponsor containing certain specified terms and conditions set forth therein and other terms and conditions customary for such agreements.

C. The parties hereto desire for the Company to provide the registration rights set out in this Agreement to the Sponsor in full and complete satisfaction of the Company’s obligations under Section 5.1 of the Subscription Agreement.

AGREEMENT

NOW, THEREFORE, the parties to this Agreement hereby agree as follows:

SECTION I. DEMAND REGISTRATIONS

1.1 Requests for Registration. Subject to the other provisions of this Section 1, the Sponsor may (on behalf of itself and any Affiliate), at any time, initiate up to eight (8) registrations of all or part of its Registrable Securities on Form S-1 or any similar or successor long-form registration (“Long-Form Registrations”) and, if available, an unlimited number of registrations of all or part of their Registrable Securities on Form S-3 or any similar or successor short-form registration (“Short-Form Registrations” and, collectively with any Long-Form Registration, the “Demand Registrations”).

1.2 Demand Notice. All requests for Demand Registrations shall be made by giving written notice to the Company (a “Demand Notice”). Each Demand Notice shall specify the approximate number of Registrable Securities requested to be registered. Within ten (10) days after receipt of any such Demand Notice, the Company will give written notice of such requested registration to all other Stockholders, if any, and, subject to Section 1.5, the Company will include in any such registration (and in all related registrations and qualifications under blue sky laws or in compliance with other registration requirements and in any related underwriting), all Registrable Securities with respect to which the Company has received written requests from such other Stockholders, if any, for inclusion therein within fifteen (15) days after the delivery of the Company’s notice.

1.3 Demand Registration Expenses. The Company will pay all Registration Expenses (as defined in Section 3.2) in connection with any registration initiated as a Demand Registration, whether or not it has become effective.

1.4 Short-Form Registrations. Demand Registrations will be Short-Form Registrations whenever the Company is permitted to use any applicable short-form (unless the managing underwriter(s) of such offering requests the Company to use a Long-Form Registration in order to sell all of the Registrable Securities requested to be sold). After the Company has become subject to the reporting requirements of the Exchange Act, the Company will use its reasonable best efforts to make Short-Form Registrations available for the sale of Registrable Securities. To the extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) (a “WKSI”) at the time any Demand Notice for a Short Form Registration is submitted to the Company in accordance with Section 1.2, the Company will use its reasonable best efforts to (i) if so requested, file an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “automatic shelf registration statement”) to effect such registration, and (ii) remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such automatic shelf registration statement is required to remain effective in accordance with this Agreement.

1.5 Priority on Demand Registrations. The Company shall not include in any Demand Registration any securities which are not Registrable Securities, other than securities of the Company to be offered by the Company solely for its own account (the “Company Offered Securities”), without the prior written consent of the Sponsor. If a Demand Registration is an underwritten offering and the managing underwriter(s) advises the Company in writing that in its opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold therein without adversely affecting the marketability of the offering, then the Company shall include in such registration, prior to the inclusion of any securities that are not Registrable Securities, other than Company Offered Securities, the number of Registrable Securities requested to be included in such offering that, in the opinion of such underwriter(s), can be sold without adversely affecting the marketability of the offering, pro rata among the respective holders thereof on the basis of the number of Registrable Securities owned by each such holder, and only after all such Registrable Securities are included in such offering, shall securities that are not Company Offered Securities or Registrable Securities, if any, be included in such offering.

1.6 Selection of Underwriters. The Sponsor shall have the right to select the underwriter or underwriters to administer the offering for any Demand Registration.

1.7 Other Registration Rights. The Company represents and warrants that it is not a party to, or otherwise subject to, any other agreement granting registration rights to any other Person with respect to any securities of the Company, other than this Agreement. Except as provided in this Agreement, for so long as any Registrable Securities are outstanding, the Company shall not grant to any Persons the right to request the Company to register any equity securities of the Company, or any securities convertible or exchangeable into or exercisable for such securities, without the approval of the Sponsor.

SECTION II. PIGGYBACK REGISTRATIONS.

2.1 Right to Piggyback.

(a) The Company will include in its Initial Public Offering all Registrable Securities held and requested by the Sponsor to be included in such registration (the “Initial Public Offering Piggyback Registration”).

(b) Following the Initial Public Offering, whenever the Company proposes to register any of its equity securities under the Securities Act, including any registration pursuant to Section 1.1 above (other in connection with registration on Form S-4 or Form S-8 or any successor or similar form) and the registration form to be used may be used for the registration of Registrable Securities (a “Non-Initial Public Offering Piggyback Registration”), the Company will give prompt written notice to all Stockholders of its intention to effect such a registration and, subject to Sections 2.3 and 2.4 below, will include in such registration all Registrable Securities held by any Stockholders upon notice from such Stockholder within fifteen (15) days after the delivery of the Company’s notice. Each such Company notice shall specify the approximate number of Company equity securities to be registered and the anticipated per share price range for such offering.

2.2 Piggyback Expenses. The Registration Expenses of the Stockholders will be paid by the Company in all Piggyback Registrations, whether or not any such registration becomes effective.

2.3 Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company and the managing underwriter(s) advises the Company in writing (with a copy to each applicable Stockholder requesting registration of Registrable Securities) that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of such offering, the Company will include in such registration: (a) first, the securities the Company proposes to sell solely for its own account, (b) second, the Registrable Securities requested to be included in such registration, pro rata among the applicable holders of such Registrable Securities on the basis of the number of shares owned by each such holder, and (c) third, other securities requested to be included in such registration.

2.4 Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s securities (other than the Stockholders with respect to Registrable Securities), and the managing underwriter(s) advises the Company in writing that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such registration: (a) first, the Registrable Securities requested to be included in such registration by the Stockholders, pro rata among the holders of such Registrable Securities on the basis of the number of Registrable Securities owned by each such holder, and (b) second, other such securities requested to be included in such registration.

SECTION III. REGISTRATION AND COORDINATION GENERALLY.

3.1 Registration Procedures. Whenever the Stockholders request that any Registrable Securities be registered pursuant to this Agreement, the Company will use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof and pursuant thereto the Company will as expeditiously as reasonably practicable:

(a) prepare and (within, in the case of a Long-Form Registration, forty-five (45) days, or, in the case of a Short-Form Registration, thirty (30) days, in each case, after the end of the period within which requests for inclusion in such registration may be given to the Company, if relevant) file with the Securities and Exchange Commission a registration statement with respect to such Registrable Securities and thereafter use its reasonable best efforts to cause such registration statement to become effective (provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company will furnish to the counsel selected by the Sponsor for any registration in which the Sponsor participates (or counsel selected by the Stockholders holding a majority of the Registrable Securities for which registration is sought, for any registration in which the Sponsor does not participate and in which the other Stockholders do participate), copies of all such documents proposed to be filed, which documents will be subject to review by such counsel);

(b) prepare and file with the Securities and Exchange Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary (i) to keep such registration statement effective (A) for at least ninety (90) days (subject to extension pursuant to Section 3.3(b)) or until each Stockholder participating in such registration has completed the distribution described in the registration statement relating to such distribution, whichever occurs first or, if such registration statement relates to an underwritten offering, such longer period as in the opinion of counsel for the underwriters a prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer, or (B) in the case of a Shelf Registration, until the earlier of (1) the date on which all Registrable Securities have been sold under the Shelf Registration or otherwise no longer qualify as Registrable Securities and (2) the latest date allowed by applicable law, and (ii) to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement until such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement;

(c) furnish to each Stockholder participating in such registration such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such Stockholder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Stockholder;

(d) use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any Stockholder participating in such registration reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such Stockholder to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Stockholder (provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, (ii) subject itself to taxation in respect of doing business in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction);

(e) promptly notify each Stockholder participating in such registration at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon discovery that, or upon the discovery of the happening of any event as a result of which, the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and, at the request of any Stockholder participating in such registration, the Company will prepare and furnish to such Stockholder a reasonable number of copies of a supplement or amendment to such prospectus so that, as thereafter delivered to the prospective purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made;

(f) cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement;

(h) if at any time when the Company is required to re-evaluate its WKSI status for purposes of an automatic shelf registration statement used to effect a request for registration in accordance with Section 1.4 (i) the Company determines that it is not a WKSI, (ii) the registration statement is required to be kept effective in accordance with this Agreement, and (iii) the registration rights of the Stockholders hereunder have not terminated, promptly amend the registration statement onto a form the Company is then eligible to use or file a new registration statement on such form, and keep such registration statement effective in accordance with the requirements otherwise applicable under this Agreement;

(i) if (i) a Shelf Registration is required to be kept effective in accordance with this Agreement after the third anniversary of the initial effective date of the Shelf Registration, (ii) the registration rights of the Stockholders hereunder have not terminated and (iii) the Company is eligible at such time to file a Shelf Registration, file a new registration statement with respect to any unsold Registrable Securities subject to the original request for registration prior to the end of the three year period after the initial effective date of the Shelf Registration, and keep such registration statement effective in accordance with the requirements otherwise applicable under this Agreement;

(j) enter into such customary agreements (including underwriting agreements in customary form) and perform the Company’s obligations thereunder and take all such other actions as the Stockholders participating in such registration or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (which might include effecting a stock split or a combination of shares);

(k) subject to reasonable confidentiality undertakings, make available for inspection by each Stockholder participating in such registration, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by such Stockholders or any such underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such Stockholder, underwriter, attorney, accountant or agent in connection with such registration statement, and to cooperate and participate as reasonably requested by any such seller in road show presentations, in the preparation of the registration statement, each amendment and supplement thereto, the prospectus included therein, and other activities as such Stockholder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Stockholder;

(l) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Securities and Exchange Commission, and make available to its security holders, as soon as reasonably practicable, but not later than fifteen (15) months after the effective date of the registration statement, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(m) in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any securities included in such registration statement for sale in any jurisdiction, the Company will use its reasonable best efforts promptly to obtain the withdrawal of such order;

(n) obtain one or more comfort letters, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, also dated the date of the closing under the underwriting agreement) addressed to the Persons participating in such offering, signed by the Company’s independent public accountants in the then-current customary form and covering such matters of the type customarily covered from time to time by comfort letters as the Stockholders participating in such registration may reasonably request;

(o) provide one or more legal opinions of the Company’s outside counsel, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering, dated the date of the closing under the underwriting agreement and addressed to the underwriters), with respect to the registration statement, each amendment and supplement thereto, the prospectus included therein (including the preliminary prospectus) and such other documents relating thereto in the then-current customary form and covering such matters of the type customarily covered from time to time by legal opinions of such nature (in a form reasonably acceptable to the Stockholders participating in such registration);

(p) cooperate with the Stockholders participating in such registration and the managing underwriter(s), if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter(s), if any, or the Sponsor may request;

(q) notify counsel for the Stockholders participating in such registration and the managing underwriter(s), immediately, and confirm the notice in writing (i) when the registration statement, or any post-effective amendment to the registration statement, shall have become effective, or any supplement to the prospectus or any amendment prospectus shall have been filed, (ii) of the receipt of any comments from the Securities and Exchange Commission, (iii) of any request of the Securities and Exchange Commission to amend the registration statement or amend or supplement the prospectus or for additional information, and (iv) of the issuance by the Securities and Exchange Commission of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the registration statement for offering or sale in any jurisdiction, or of the institution or threatening of any proceedings for any of such purposes;

(r) use its reasonable best efforts to prevent the issuance of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus;

(s) if requested by the managing underwriter(s) or any Stockholder participating in such registration, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter(s) or such Stockholder reasonably requests to be included therein, including, without limitation, with respect to the number of Registrable Securities being sold by such Stockholder to such underwriter or agent, the purchase price being paid therefor by such underwriter or agent and with respect to any other terms of the underwritten offering of the Registrable Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters incorporated in such prospectus supplement or post-effective amendment; and

(t) cooperate with each Stockholder participating in such registration and each underwriter or agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority, Inc.

The Company may require each Stockholder participating in such registration to furnish the Company such information relating to the sale or registration of such securities regarding such Stockholder and the distribution of such securities as the Company hereunder may from time to time reasonably request in writing.

3.2 Registration Expenses.

(a) All expenses incident to the Company’s performance of or compliance with this Agreement, including, without limitation, all registration, qualification and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, transfer agent’s and registrar’s fees, cost of distributing prospectuses in preliminary and final form as well as supplements thereto and fees and disbursements of counsel for the Company and all independent certified public accountants, underwriters (excluding discounts and commissions) and other Persons retained by the Company (all such expenses, as well as any expenses identified in Section 3.2(b), being herein called “Registration Expenses”), will be paid by the Company in respect of each Demand Registration and each Piggyback Registration, whether or not it has become effective, including that the Company will pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed; provided, that all underwriting discounts and commissions and transfer taxes, if any, attributable to the sale of equity securities of the Company shall not be included as Registration Expenses and shall be borne by the applicable seller of such equity securities of the Company.

(b) In connection with each Demand Registration and each Piggyback Registration, whether or not it has become effective, the Company will pay, and reimburse the Stockholders for the payment of, the reasonable fees and disbursements of one counsel selected by the Sponsor (or counsel selected by the Stockholders holding a majority of the Registrable Securities for which registration is sought, for any registration in which the Sponsor does not participate and in which the other Stockholders do participate), and such expenses shall be considered Registration Expenses hereunder.

3.3 Participation in Underwritten Offerings.

(a) No Stockholder may participate in any registration hereunder which is underwritten unless such Stockholder (i) agrees to sell its securities on the basis provided in any underwriting arrangements approved by the Sponsor (or the Stockholders holding a majority of the Registrable Securities for which registration is sought, for any registration in which the Sponsor does not participate and in which the other Stockholders do participate) including, without limitation, pursuant to the terms of any over-allotment or “green shoe” option requested by the managing underwriter(s), provided that such Stockholder will not be required to sell more than the number of Registrable Securities that such Stockholder has requested the Company to include in any registration, and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

(b) Each Stockholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.1(e) above, such Stockholder will forthwith discontinue the disposition of its Registrable Securities pursuant to the registration statement until such Stockholder’s receipt of the copies of a supplemented or amended prospectus as contemplated by such Section 3.1(e). In the event the Company shall give any such notice, the applicable time period mentioned in Section 3.1(b) during which a Registration Statement is to remain effective shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this paragraph to and including the date when such Stockholder shall have received the copies of the supplemented or amended prospectus contemplated by Section 3.1(e).

3.4 Company Holdback. The Company shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, with respect to any other underwritten Demand Registration or any underwritten Piggyback Registration in which Registrable Securities are included, during the seven (7) days prior to and the ninety (90)-day period beginning on the effective date of such registration, and (c) upon notice from the Sponsor that the Stockholders intend to effect an underwritten distribution of Registrable Securities pursuant to a Shelf Registration, the seven (7) days prior to and the ninety (90)-day period beginning on the date of the commencement of such distribution, in each case except as part of such underwritten registration or pursuant to registrations on Form S-4 or Form S-8, and in each case unless the managing underwriter(s) otherwise agrees.

3.5 Current Public Information. At all times after the Company has filed a registration statement with the Securities and Exchange Commission pursuant to the requirements of either the Securities Act or the Exchange Act, the Company will use its reasonable best efforts to timely file all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the Securities and Exchange Commission thereunder, and will take such further action as any holder or holders of Registrable Securities may reasonably request, all to the extent required to enable such holders to sell Registrable Securities pursuant to Rule 144.

3.6 Shelf Take-Downs. At any time that a Shelf Registration is effective, if a Stockholder delivers a notice to the Company (a “Take-Down Notice”) stating that it intends to effect an offering of all or part of its Registrable Securities included by it on the Shelf Registration, whether such offering is underwritten or non-underwritten (a “Shelf Offering”) and stating the number of the Registrable Securities to be included in the Shelf Offering, then, the Company shall amend or supplement the Shelf Registration as may be necessary in order to enable such Registrable Securities to be distributed pursuant to the Shelf Offering. In connection with any Shelf Offering, in the event that the managing underwriter(s), if any, advises the Company in writing that in its opinion the number of Registrable Securities to be included in such Shelf Offering exceeds the number of Registrable Securities which can be sold therein without adversely affecting the marketability of the offering, such managing underwriter(s), if any, may limit the number of shares which would otherwise be included in such Shelf Offering in the same manner as is described in Section 1.5.

SECTION IV. INDEMNIFICATION.

4.1 Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Stockholder and, as applicable, its officers, directors, trustees, employees, stockholders, holders of beneficial interests, members, and general and limited partners (collectively, such Stockholder’s “Indemnitees”) and each Person who controls such Stockholder (within the meaning of the Securities Act) against any and all losses, claims, damages, liabilities, joint or several, to which such Stockholder or any such Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (a) any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, together with any documents incorporated therein by reference or, (b) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse such Stockholder and each of its Indemnitees for any legal or any other expenses, including any amounts paid in any settlement effected with the consent of the Company, which consent will not be unreasonably

withheld or delayed, incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished to the Company by such Stockholder expressly for use therein. In connection with an underwritten offering, the Company will indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of such Stockholder.

4.2 Indemnification by the Stockholders. In connection with any registration statement in which a Stockholder is participating, each such Stockholder will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, will indemnify and hold harmless the Company and its Indemnitees against any losses, claims, damages, liabilities, joint or several, to which the Company or any such Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (a) any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or in any application, together with any documents incorporated therein by reference or (b) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto, or in any application, in reliance upon and in conformity with written information prepared and furnished to the Company by such Stockholder expressly for use therein, and such Stockholder will reimburse the Company and each such Indemnitee for any legal or any other expenses including any amounts paid in any settlement effected with the consent of such Stockholder, which consent will not be unreasonably withheld or delayed, incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided, however, that the obligation to indemnify will be individual (and not joint and several) to each Stockholder and will be limited to the net amount of proceeds received by such Stockholder from the sale of Registrable Securities pursuant to such registration statement, less any other amounts paid by such Stockholder in respect of such untrue statement, alleged untrue statement, omission or alleged omission.

4.3 Procedure. Any Person entitled to indemnification hereunder will (a) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided, however, that the failure of any indemnified party to give such notice shall not relieve the indemnifying party of its obligations hereunder, except to the extent that the indemnifying party is actually prejudiced by such failure to give such notice), and (b) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.

4.4 Entry of Judgment; Settlement. The indemnifying party shall not, except with the approval of each indemnified party, 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 each indemnified party of a release from all liability in respect to such claim or litigation without any payment or consideration provided by such indemnified party.

4.5 Contribution. If the indemnification provided for in this Section 4 is, other than expressly pursuant to its terms, unavailable to or is insufficient to hold harmless an indemnified party under the provisions above in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (a) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and each Stockholder and any other sellers participating in the registration on the other hand from the sale of Registrable Securities pursuant to the registered offering of securities as to which indemnity is sought or (b) if the allocation provided by clause (a) above is not permitted by applicable law, in such proportion as is appropriate to reflect the relative benefits referred to in clause (a) above but also the relative fault of the Company on the one hand and of the Stockholders and any other sellers participating in the registration on the other hand in connection with the statement or omissions which 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 Stockholders and any other sellers participating in the registration on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) to the Company bear to the total net proceeds from the offering (before deducting expenses) to the Stockholders and any other sellers participating in the registration. The relative fault of the Company on the one hand and of the Stockholders and any other sellers participating in the registration on the other hand shall be determined by reference to, among other things, whether the untrue or alleged statement or omission to state a material fact relates to information supplied by the Company or by the Stockholders or other sellers participating in the registration and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Stockholders participating in the registration agree that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation (even if the Stockholders participating in the registration were treated as one entity for such purposes) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. 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 4, no Stockholder participating in the registration shall be required to contribute any amount in excess of the net proceeds received by such Stockholder from the sale of Registrable Securities covered by the relevant registration statement filed pursuant hereto, less any other amounts paid by such Stockholder in respect of such untrue statement, alleged untrue statement, 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.

4.6 Other Rights. The indemnification and contribution by any such party provided for under this Agreement shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and will remain in full force and effect regardless of any investigation made or omitted by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of securities.

SECTION VII. MISCELLANEOUS.

7.1 No Inconsistent Agreements. The Company will not hereafter enter into any agreement with respect to its securities which is inconsistent with or violates the rights granted to the Stockholders in this Agreement.

7.2 Adjustments Affecting Registrable Securities. The Company will not take any action, or permit any change to occur, with respect to its securities which would materially and adversely affect the ability of the Stockholders to include its Registrable Securities in a registration undertaken pursuant to this Agreement (including, without limitation, effecting a stock split, stock dividend, reclassification, reorganization or similar transaction). If the Company or any Affiliate creates a new holding company (“Holdco”) or otherwise engages in any reorganization of any kind, the result of which is that the stockholders of the Company immediately before such event become all the stockholders of Holdco or such other successor entity, then in each instance the provisions of this Agreement will, in addition to applying to the Company, also apply to Holdco or such other successor entity in the same manner as if Holdco or such other successor entity were substituted for the Company throughout this Agreement.

7.3 Amendment and Waiver. This Agreement may be amended, modified, extended, terminated or waived (an “Amendment”), and the provisions hereof may be waived, only by an agreement in writing signed by the Company and the Sponsor. Each such Amendment shall be binding upon each party hereto. In addition, each party hereto and each Stockholder subject hereto may waive any right hereunder, as to itself, by an instrument in writing signed by such party. The failure of any party to enforce any provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. To the extent the Amendment of any Section of this Agreement would require a specific consent pursuant to this Section 7.3, any Amendment to the definitions used in such Section as applied to such Section shall also require the same specified consent.

7.4 Successors and Assigns; Transferees. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns. Registrable Securities shall continue to be Registrable Securities after any Transfer pursuant to which the transferee is deemed to hold “restricted securities” as such term is defined in Rule 144(a)(3); provided, however, that Registrable Securities shall not continue to be Registrable Securities if such securities were effectively registered under the Securities Act and disposed of in accordance with the registration statement covering them. Any transferee receiving shares of Registrable Securities in a Transfer shall become a Stockholder party to this Agreement and subject to the terms and conditions of, and be entitled to enforce, this Agreement to the same extent, and in the same capacity, as the Person that Transfers such shares to such transferee. If the Sponsor Transfers 100% of its Registrable Securities, the term “Sponsor” hereunder shall be deemed to include all Stockholders, if any, and any exercise of rights by the Stockholders in such capacity shall be determined by Stockholders holding a majority of Registrable

Securities then outstanding. Prior to the Transfer of any Registrable Securities to any transferee, and as a condition thereto, each Stockholder effecting such Transfer shall cause such transferee to deliver to the Company a joinder agreement, in form and substance reasonably satisfactory to the Company, to be bound by the terms and conditions of this Agreement.

7.5 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or the effectiveness or validity of any provision in any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

7.6 Counterparts. This Agreement may be executed in separate counterparts (including by means of facsimile or electronic transmission in portable document format (pdf)), each of which shall be an original and all of which taken together shall constitute one and the same Agreement.

7.7 Descriptive Headings. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

7.8 Notices. Any notices and other communications required or permitted in this Agreement shall be effective if in writing and (a) delivered personally, (b) sent by facsimile or electronic transmission, or (c) sent by overnight courier, in each case, addressed as follows:
