3. Method of Exercise; Payment; Issuance of New Warrant; Net Issuance.

(a) Subject to Section 2 hereof, the purchase right represented by this Warrant may be exercised by the Holder, in whole or in part and from time to time, at the election of the Holder, by (a) the surrender of this Warrant (with the notice of exercise substantially in the form attached hereto as Exhibit A-1 duly completed and executed) at the principal office of the Company and by the payment to the Company, by certified or bank check, or by wire transfer to an account designated by the Company (a “Wire Transfer”) of an amount equal to the then applicable Warrant Price multiplied by the number of Shares then being purchased; (b) if in connection with a registered public offering of the Company’s securities, the surrender of this Warrant (with the notice of exercise form attached hereto as Exhibit A-2 duly completed and executed) at the principal office of the Company together with notice of arrangements reasonably satisfactory to the Company for payment to the Company from the proceeds of the sale of shares to be sold by the Holder in such public offering of an amount equal to the then applicable Warrant Price per share multiplied by the number of Shares then being purchased; or (c) exercise of the “net issuance” right provided for in Section 3(b) hereof. The person or persons in whose name(s) Shares shall be registered upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the shares represented thereby (and such shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised. In the event of any exercise of this Warrant, certificates for the shares of stock so purchased shall be delivered to the Holder as soon as possible and in any event within thirty (30) days after such exercise and, unless this Warrant has been fully exercised or expired, a new Warrant representing the portion of the Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder as soon as possible and in any event within such thirty-day period; provided, however, that at such time as the Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, if requested by the Holder, the Company shall cause its transfer agent to deliver the certificate representing Shares issued upon exercise of this Warrant to, or credit the securities account of, a broker or other person (as directed by the Holder exercising this Warrant) within the time period required to settle any trade made by the Holder after exercise of this Warrant.

(b) Right to Convert Warrant into Stock: Net Issuance.

(i) Right to Convert. In addition to and without limiting the rights of the Holder under the terms of this Warrant, the Holder shall have the right to convert this Warrant or any portion thereof (the “Conversion Right”) into shares of Series Preferred as provided in this Section 3(b) at any time or from time to time during the term of this Warrant. Upon exercise of the Conversion Right with respect to a particular number of shares subject to this Warrant (the “Converted Warrant Shares”), the Company shall deliver to the Holder (without payment by the Holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Series Preferred as is determined according to the following formula:

-3-

(ii) Method of Exercise. The Conversion Right may be exercised by the Holder by the surrender of this Warrant at the principal office of the Company together with a written statement (which may be in the form of Exhibit A-1 or Exhibit A-2 hereto) specifying that the Holder thereby intends to exercise the Conversion Right and indicating the number of shares subject to this Warrant which are being surrendered (referred to in Section 3(b)(i) hereof as the Converted Warrant Shares) in exercise of the Conversion Right. Such conversion shall be effective upon receipt by the Company of this Warrant together with the aforesaid written statement, or on such later date as is specified therein (the “Conversion Date”), and, at the election of the Holder, may be made contingent upon the closing of the sale of the Company’s Common Stock to the public in a public offering pursuant to a registration statement under the Act (a “Public Offering”).

(iii) Determination of Fair Market Value. For purposes of this Section 3(b), “fair market value” of a share of Series Preferred (or Common Stock if the Series Preferred has been automatically converted into Common Stock) as of a particular date (the “Determination Date”) shall mean:

(1) If the Conversion Right is exercised in connection with and contingent upon a Public Offering, and if the Company’s registration statement relating to such Public Offering (“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “Price to Public” specified in the final prospectus with respect to such Public Offering.

(2) If the Conversion Right is not exercised in connection with and contingent upon a Public Offering, then as follows:

(A) If traded on a securities exchange, the fair market value of the Common Stock shall be deemed to be the average of the closing prices of the Common Stock on such exchange over the five trading days immediately prior to the Determination Date, and the fair market value of the Series Preferred shall be deemed to be such fair market value of the Common Stock multiplied (if the Series Preferred is not then constituted as Common Stock) by the number of shares of Common Stock into which each share of Series Preferred is then convertible;

(B) If traded on the Nasdaq Stock Market or other over-the-counter system, the fair market value of the Common Stock shall be deemed to be the average of the closing bid prices of the Common Stock over the five trading days immediately prior to the Determination Date, and the fair market value of the Series Preferred shall be deemed to be such fair market value of the Common Stock multiplied (if the Series Preferred is not then constituted as Common Stock) by the number of shares of Common Stock into which each share of Series Preferred is then convertible; and

(C) If there is no public market for the Common Stock, then fair market value shall be reasonably determined in good faith by the board of directors of the Company.

(iv) In making a determination under clauses (A) or (B) above, if on the Determination Date, five trading days had not passed since the IPO, then the fair market value of the Common Stock shall be the average closing prices or closing bid prices, as applicable, for the shorter period beginning on and including the first trading day after the pricing of the IPO and ending on the trading day prior to the Determination Date (or if such period includes only one trading day the closing price or closing bid price, as applicable, for such trading day). If closing prices or closing bid prices are no longer reported by a securities exchange or other trading system, the closing price or closing bid price shall be that which is reported by such securities exchange or other trading system at 4:00 p.m. New York City time on the applicable trading day.

4. Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all preemptive rights and taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of its Series Preferred to provide for the exercise of the rights represented by this Warrant and, while applicable, a sufficient number of shares of its Common Stock to provide for the conversion of the Series Preferred into Common Stock.

5. Adjustment of Warrant Price and Number of Shares. The number and kind of securities purchasable upon the exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a) Corporate Events.

(i) In case of (A) any reclassification or change of securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or (B) in case of any merger of the Company with or into another corporation (other than a merger with another corporation in which the Company is the acquiring and the surviving corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant) (each, a “Corporate Event”), the Company, or such successor corporation, as the case may be, shall duly execute and deliver to the Holder a new Warrant (in form and substance satisfactory to the Holder), or the Company shall make appropriate provision without the issuance of a new Warrant, so that the Holder shall have the right to receive upon exercise of this Warrant, at a total purchase price not to exceed that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the shares of Series Preferred theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such Corporate Event by a holder of the number of shares of Series Preferred then purchasable under this Warrant. Any new Warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The provisions of this Section 5(a)(i) shall similarly apply to successive Corporate Events.

(ii) Notwithstanding anything to the contrary set forth in Section 5(a)(i), in the event of a Corporate Event (other than a Corporate Event described in clause (A) of such defined term), any sale of all or substantially all of the assets of the Company or an IPO, in which Holder has not exercised this Warrant in accordance with the terms of either Sections 3(a) or 3(b) above, at Holder’s option, immediately prior to, and contingent upon, the consummation of any such transaction, Holder may elect to surrender this Warrant to the Company in exchange for a cash payment in an amount equal to the product of (x) two (2) times the Warrant Price then in effect and (y) the number of shares of Series Preferred issuable pursuant to the terms hereof had Holder elected to exercise this Warrant immediately prior to the consummation of such transaction.

(b) Subdivision or Combination of Shares. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Series Preferred, the Warrant Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision and the Warrant Price shall be proportionately increased and the number of Shares issuable hereunder shall be proportionately decreased in the case of a combination.

(c) Stock Dividends and Other Distributions. If the Company at any time while this Warrant is outstanding and unexpired shall (i) pay a dividend with respect to Series Preferred payable in Series Preferred, then the Warrant Price shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the Warrant Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Series Preferred outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total

-5-

number of shares of Series Preferred outstanding immediately after such dividend or distribution; or (ii) make any other distribution with respect to Series Preferred (except any distribution specifically provided for in Sections 5(a) and 5(b)), then, in each such case, provision shall be made by the Company such that the Holder shall receive upon exercise of this Warrant a proportionate share of any such dividend or distribution as though it were the holder of the Series Preferred (or Common Stock issuable upon conversion thereof) as of the record date fixed for the determination of the shareholders of the Company entitled to receive such dividend or distribution.

(d) Adjustment of Number of Shares. Upon each adjustment in the Warrant Price, the number of Shares of Series Preferred purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter.

(e) Antidilution Rights. The other antidilution rights applicable to the Shares of Series Preferred purchasable hereunder are set forth in the Company’s Certificate of Incorporation, as amended through the Date of Grant, a true and complete copy of which is attached hereto as Exhibit B (the “Charter”). If the Company proposes a restatement, amendment, modification or waiver of antidilution rights that treats the Holder disproportionately in an adverse manner than the other holders of the Shares of Series Preferred purchasable hereunder with respect to such antidilution rights, then such restatement, amendment, modification or waiver shall require the consent of the Holder. The Company shall promptly provide the Holder with any restatement, amendment, modification or waiver of the Charter promptly after the same has been made.

6. Notice of Adjustments. Whenever the Warrant Price or the number of Shares purchasable hereunder shall be adjusted pursuant to Section 5 hereof, the Company shall deliver to Holder a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Price and the number of Shares purchasable hereunder after giving effect to such adjustment. In addition, whenever the conversion price or conversion ratio of the Series Preferred shall be adjusted, the Company shall deliver to Holder a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the conversion price or ratio of the Series Preferred after giving effect to such adjustment. Whenever the Warrant Price or the number of Shares purchasable hereunder shall be fixed according to a formula based upon the occurrence of an event or events subsequent to the Date of Grant, at the end of the period during which the event or events can occur, the Company shall deliver to Holder a certificate signed by its chief financial officer setting forth the Warrant Price and/or number of Shares purchasable hereunder, and, in reasonable detail, the calculation of the Warrant Price and/or such number of Shares.

7. Fractional Shares. No fractional shares of Series Preferred will be issued in connection with any exercise or conversion hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor based on the fair market value of the Series Preferred on the date of exercise or conversion as reasonably determined in good faith by the Company’s Board of Directors.

8. Compliance with Act; Disposition of Warrant or Shares of Series Preferred.

(a) Compliance with Act. The Holder, by acceptance hereof, agrees that this Warrant, and the shares of Series Preferred to be issued upon exercise hereof and any Common Stock issued upon conversion thereof are being acquired for investment and that the Holder will not offer, sell or otherwise dispose of this Warrant, or any shares of Series Preferred to be issued upon exercise hereof or any Common Stock issued upon conversion thereof except under circumstances which will not result in a violation of the Act or any applicable state securities laws. Upon exercise of this Warrant, unless the Shares being acquired are registered under the Act and any applicable state securities laws or an exemption from such registration is available, the Holder shall confirm in writing that the shares of Series Preferred so purchased (and any Common Stock issued upon conversion thereof) are being acquired for investment and not with a view toward distribution or resale in violation of the Act and shall confirm such other matters related thereto as may be

-6-

reasonably requested by the Company. This Warrant and all shares of Series Preferred issued upon exercise of this Warrant and all Common Stock issued upon conversion thereof (unless registered under the Act and any applicable state securities laws) shall be stamped or imprinted with a legend in substantially the following form:

“THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED, (iii) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE PROVISIONS OF SECTION 8 OF THE WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY.”

Said legend shall be removed by the Company, upon the request of the Holder, at such time as the restrictions on the transfer of the applicable security shall have terminated. In addition, in connection with the issuance of this Warrant, the Holder specifically represents to the Company by acceptance of this Warrant as follows:

(1) The Holder is aware of the Company’s business affairs and financial condition, and has acquired information about the Company sufficient to reach an informed and knowledgeable decision to acquire this Warrant. The Holder is acquiring this Warrant for its own account for investment purposes only and not with a view to, or for the resale in connection with, any “distribution” thereof in violation of the Act.

(2) The Holder understands that this Warrant has not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein.

(3) The Holder further understands that this Warrant and the Series Preferred must be held indefinitely unless subsequently registered under the Act and qualified under any applicable state securities laws, or unless exemptions from registration and qualification are otherwise available. The Holder is aware of the provisions of Rule 144, promulgated under the Act.

(4) The Holder is an “accredited investor” as such term is defined in Rule 501 of Regulation D promulgated under the Act.

(b) Disposition of Warrant or Shares. With respect to any offer, sale or other disposition of this Warrant or any shares of Series Preferred acquired pursuant to the exercise of this Warrant, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of counsel, or other evidence, if reasonably satisfactory to the Company, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such shares of Series Preferred or Common Stock and indicating whether or not under the Act certificates for this Warrant or such shares of Series Preferred to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory opinion or other evidence, the Company, as promptly as practicable but no later than fifteen (15) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of this Warrant or such shares of Series Preferred or Common Stock, all in accordance with the terms of the notice delivered to the Company. If a determination has been made pursuant to this Section 8(b) that the opinion of counsel or other evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such determination has been made. Notwithstanding the foregoing, this Warrant or such shares of Series Preferred or Common Stock may, as to such federal laws, be offered, sold or otherwise disposed of (i) pursuant to an effective registration statement covering such securities or (ii) in accordance with Rule 144 or 144A under the Act, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 or 144A have been satisfied.

-7-

Each certificate representing this Warrant or the shares of Series Preferred thus transferred (except a transfer pursuant to an effective registration statement or Rule 144 or 144A) shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions.

(c) Applicability of Restrictions. Neither any restrictions of any legend described in this Warrant nor the requirements of Section 8(b) above shall apply to any transfer of, or grant of a security interest in, this Warrant (or the Series Preferred or Common Stock obtainable upon exercise thereof) or any part hereof (i) to a partner of the Holder if the Holder is a partnership or to a member of the Holder if the Holder is a limited liability company, (ii) to a partnership of which the Holder is a partner or to a limited liability company of which the Holder is a member, or (iii) to a single affiliate of the Holder if the Holder is a corporation, where, in each case, the transferee is an “accredited investor”. [To be used for Horizon Warrant: In addition to the foregoing, Holder may transfer this Warrant (i) to any corporation, company, limited liability company, limited partnership, partnership, or other person managed or sponsored by [            ] (“Finance LLC”) or its principals or in which Finance LLC has an interest, (ii) to Horizon Credit I LLC or (iii) to a lender of the Holder or any of the foregoing.] In any such transfer described in this Section 8(c), if applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of this Warrant as if an original holder hereof.

9. Rights as Shareholders; Information. No Holder, as a holder of this Warrant, shall be entitled to vote or receive dividends or be deemed the holder of Series Preferred or any other securities of the Company which may at any time be issuable upon the exercise or conversion hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised or converted and the Shares purchasable upon the exercise or conversion hereof shall have become deliverable, as provided herein. Notwithstanding the foregoing, the Company will transmit to the Holder such information, documents and reports as are generally distributed to the holders of Series Preferred or Common Stock concurrently with the distribution thereof to the shareholders. In addition, the Company agrees to provide in a timely manner any information reasonably requested by the Holder to enable the Holder and its affiliates to comply with their accounting reporting requirements.

10. Market Stand-Off Agreement. Holder shall not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by Holder (other than those included in the registration), for a period of time specified by the managing underwriter(s) (not to exceed one hundred eighty (180) days) (or such longer period as the underwriters or the Company shall request in order to facilitate compliance with NASD Rule 2711 so long as the investors party to the Registration Rights Agreement (as defined below) are also subject to such extension) following the effective date of a registration statement of the Company filed under the Act. Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the managing underwriter(s) which are consistent with the foregoing or which are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to such Common Stock (or other securities) until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 10 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

11. Registration Rights. The Company grants registration rights to the Holder of this Warrant for any Common Stock of the Company obtained upon conversion of the Series Preferred, the registration rights granted to the investors in that certain Amended and Restated Investors’ Rights Agreement dated as of December 11, 2007, (as may be amended from time to time, the “Registration Rights Agreement”), with the following exceptions and clarifications:

-8-

(a) The Holder will only participate in a “piggyback” registration demanded by others, but will not have the right to demand registration.

(b) The Holder will be subject to the same provisions, including regarding indemnification, as contained in the Registration Rights Agreement.

(c) The registration rights are freely assignable by the Holder of this Warrant in connection with a permitted transfer of this Warrant or the Shares.

12. Additional Rights.

The Company shall provide the Holder with at least twenty (20) days’ written notice prior to closing thereof of the terms and conditions of any of the following transactions (to the extent the Company has notice thereof): (i) the sale, lease, exchange, conveyance or other disposition of all or substantially all of the Company’s property or business, or (ii) its merger into or consolidation with any other corporation (other than a wholly-owned subsidiary of the Company) in which the Security holders of the Company immediately prior to such merger or consolidation do not own at least a majority of the voting power of the surviving corporation, or any transaction (including a merger or other reorganization) or series of related transactions, in which more than 50% of the voting power of the Company is transferred. In addition, in the event the Company proposes to enter into a Corporate Event (other than a Corporate Event described in clause (A) of such defined term), any sale of all or substantially all of the assets of the Company or an IPO, the Company shall provide the Holder with at least twenty (20) days’ written notice prior to closing thereof of the terms and conditions of such event and specifying that Holder may elect to (i) exercise its purchase right in accordance with the provisions of Section 3(a) hereof, if applicable, (ii) exercise its Conversion Right in accordance with the provisions of Section 3(b) hereof, (iii) receive a new Warrant or receive appropriate provisions without the issuance of a new Warrant in accordance with the provisions of Section 5(a)(i) hereof, if applicable, (iv) surrender this Warrant in exchange for cash payment in accordance with the provisions of Section 5(a)(ii) hereof, or (v) allow this Warrant to continue in effect until this Warrant is exercised pursuant to the terms hereof or expires, if applicable.

(b) Exercise Prior to Expiration. To the extent this Warrant is not previously exercised as to all of the Shares subject hereto, and if the fair market value of one share of the Series Preferred is greater than the Warrant Price then in effect, this Warrant shall be deemed automatically exercised pursuant to Section 3(b) above (even if not surrendered) immediately before its expiration. For purposes of such automatic exercise, the fair market value of one share of the Series Preferred upon such expiration shall be determined pursuant to Section 3(b). To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 12(b), the Company agrees to promptly notify the Holder of the number of Shares, if any, the Holder is to receive by reason of such automatic exercise.
