(b) The Subscriber is acquiring the Subscription Shares solely for the Subscriber’s own beneficial account, for investment purposes, and not with a view to, or for resale in connection with, any distribution of the Subscription Shares and Subscriber has not entered into any put, call, participation or similar arrangements, directly or indirectly, with respect to the Subscription Shares. The Subscriber has sufficient liquidity to hold its investment in the Subscription Shares indefinitely. The Subscriber understands that the Subscription Shares have not been and will not be registered under the Securities Act, the securities laws of any state thereof or the securities laws of any other jurisdiction, nor is such registration contemplated, and that they are being offered and sold pursuant to an exemption from such registration and qualification. The Subscriber understands that the Company is relying upon the representations and agreements contained in this Subscription Agreement (and any supplemental information) for the purpose of determining whether this transaction meets such exemptions.

(c) The Subscriber understands and agrees that it may not sell or dispose of any Subscription Shares except pursuant to an effective registration statement under, or in a transaction exempt from, the registration requirements of the Securities Act and any other applicable securities laws, and in the case of a transaction exempt from registration, unless the Company has received an opinion of counsel to the Company reasonably satisfactory to it that such transaction does not require registration under the Securities Act or such other applicable securities laws. Except as set forth in Section 5, the Subscriber understands that the Company has no obligation or intention to register any of the Subscription Shares or the offering or sale thereof, or to take action so as to permit offers or sales pursuant to the Securities Act or an exemption from registration thereunder (including pursuant to Rule 144 thereunder).

(e) The Subscriber has no need for liquidity in connection with its purchase of the Subscription Shares, understands that his investment carries a high degree of risk, and can bear the risk of loss of its entire investment in the Subscription Shares for an indeterminate period of time. The Subscriber is familiar with the operations of the Company and its subsidiaries, and has received all the information it deems necessary or desirable in making an informed investment decision. The undersigned has had the opportunity to ask questions of, and receive answers from, the Company concerning the terms and conditions of the offering of Subscription Shares in the Company and to obtain such information, to the extent such persons possessed or could acquire it without unreasonable effort or expense, as the undersigned deemed necessary or desirable in making an informed investment decision. The Subscriber represents that it is not relying on (and will not at any time rely on) any communication of the Company, as investment advice or as a recommendation to purchase the Subscription Shares and the Subscriber has made its own independent decision that the investment in the Subscription Shares is suitable and appropriate for the Subscriber.

In deciding to purchase the Subscription Shares, the undersigned is not relying on the advice or recommendations of the Company and the undersigned has made its own independent decision that the investment in the Subscription Shares is suitable and appropriate for the undersigned.

(g) The Subscriber understands the risks associated with an investment in the Company and has consulted its own attorney, accountant, tax, financial or investment adviser with respect to the investment contemplated hereby and its suitability for the Subscriber.

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements contained herein and for other good and valuable consideration, the sufficiency of which is agreed, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Lock-Up Provisions.

(a) The Subscriber hereby agrees not to, during the period (the “Post-Closing Lock-Up Period”) commencing on the date hereof and ending on the earlier of (i) the one year anniversary of the date hereof and (ii) the date after the date hereof on which the Company consummates a liquidation, merger, share exchange, reorganization or other similar transaction with an unaffiliated third party that results in all of the Company’s stockholders having the right to exchange their equity holdings in the Company for cash, securities or other property, without the prior written consent of the Company: (A) lend, offer, pledge, hypothecate, encumber, donate, assign, 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, establish or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) promulgated thereunder, or otherwise transfer or dispose of, directly or indirectly, any Securities, (B) 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 Securities, whether any such transaction is to be settled by delivery of such Securities, in cash or otherwise, or (C) publicly announce the intention to do any

of the foregoing, whether any such transaction described in clauses (A), (B) or (C) above is to be settled by delivery of Securities or other securities, in cash or otherwise (any of the foregoing described in clauses (A), (B) or (C), a “Prohibited Transfer”). The foregoing sentence shall not apply to the transfer of any or all of the Securities owned by the Subscriber (i) by gift, will or intestate succession upon the death of the Subscriber, (ii) to any Permitted Transferee (as defined below), (iii) pursuant to a final court order or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union or pursuant to a domestic relations order, (iv) to the Company in connection with the “net” or “cashless” exercise of options or other rights to purchase Securities granted pursuant to an equity incentive plan, stock purchase plan or other arrangement in satisfaction of any tax withholding obligations through cashless surrender or otherwise (provided any Securities issued upon exercise of such option or other rights shall remain subject to the terms of this Agreement), or (v) in connection with the exercise or conversion of any Derivative Instruments (defined below); provided, however, that in any of the cases of clauses (i), (ii) or (iii) it shall be a condition to such transfer that the transferee executes and delivers to the Company an agreement stating that the transferee is receiving and holding the Securities subject to the provisions of this Agreement applicable to the Subscriber, and there shall be no further transfer of such Securities except in accordance with this Agreement. As used in this Agreement, the term “Permitted Transferee” shall mean: (i) the members of the Subscriber’s immediate family (for purposes of this Agreement, “immediate family” shall mean with respect to any natural person, any of the following: such person’s spouse, the siblings of such person and his or her spouse, and the direct descendants and ascendants (including adopted and step children and parents) of such person and his or her spouses and siblings), (ii) any trust or charitable organization for the direct or indirect benefit of the Subscriber or the immediate family of the Subscriber, (iii) if the Subscriber is a trust, the trustor or beneficiary of such trust or to the estate of a beneficiary of such trust, (iv) if the Subscriber is an entity, as a distribution to limited partners, shareholders, members of, or owners of similar equity interests in the Subscriber, or (iv) to any affiliate of the Subscriber. The Subscriber further agrees to execute such agreements as may be reasonably requested by the Company that are consistent with the foregoing or that are necessary to give further effect thereto. Notwithstanding the foregoing, the Subscriber shall be permitted to establish a trading plan pursuant to Rule 10b5-1 promulgated under the Exchange Act, provided that (i) such plan does not provide for the transfer, sale or other disposal of Securities during the Post-Closing Lock-Up Period and (ii) any public announcement or filing with the SEC under the Exchange Act made by any person regarding the establishment of such plan during the Post-Closing Lock-Up Period shall include a statement that the undersigned is not permitted to transfer, sell or otherwise dispose of securities under such plan during the Post-Closing Lock-Up Period in contravention of this Agreement.

(b) Notwithstanding anything contained herein to the contrary, (i) 33.33% of the Securities subject to the restrictions set forth in Section 1(a) held by the Subscriber as of the Closing Date will be automatically released from the restrictions contained in Section 1(a) immediately prior to the opening of The Nasdaq Global Market on the six month anniversary of the Closing Date and (ii) 33.33% of the Securities subject to the restrictions set forth in Section 1(a) held by the Subscriber as of the Closing Date will be automatically released from the restrictions contained in Section 1(a) immediately prior to the opening of The Nasdaq Global Market on the nine month anniversary of the Closing Date.

(c) Notwithstanding anything contained herein to the contrary, if, prior to the expiration of the Post-Closing Lock-Up Period, the Company consents at its discretion to release any shares of Class A Common Stock or any Securities convertible into, exchangeable for or that represent the right to receive shares of Class A Common Stock (such options, warrants or other securities, collectively, “Derivative Instruments”), held by any directors, officers, stockholders of 5.0% or more of the then outstanding shares of Common Stock of the Company that has delivered a lock-up agreement to the Company, other than the Subscriber, from the restrictions described herein (any such release being a “Triggering Release” and such party receiving such release being a “Triggering Release Party”), then a number of the Subscriber’s Securities subject to this Agreement shall also be released from the restrictions set forth herein on the same

2

terms on a pro rata basis, such number of the Subscriber’s Securities being the total number of Securities held by the Subscriber on the date of the Triggering Release that are subject to this Agreement multiplied by a fraction, the numerator of which shall be the number of Securities and Derivative Instruments released pursuant to the Triggering Release and the denominator of which shall be the total number of shares of Securities and Derivative Instruments held by the Triggering Release Party on such date that were subject to a lock-up restriction (e.g., restrictions similar to this Section 1) immediately prior to such release.

(d) If any transfer of Securities is made or attempted contrary to the provisions of this Agreement, such purported transfer shall be null and void ab initio, and the Company shall refuse to recognize any such purported transferee of the Securities as one of its equity holders for any purpose. In order to enforce this Section 1, the Company may impose stop-transfer instructions with respect to the Securities of the Subscriber (and Permitted Transferees and assigns thereof) (including through its transfer agent) until the end of the Post-Closing Lock-Up Period.

The Company may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise) or affiliate without obtaining the consent or approval of the Subscriber.

(b) Third Parties. Nothing expressed or implied in this Agreement is intended or shall be construed to confer upon or give any person, other than the parties hereto, any right or remedies under or by reason of this Agreement.
