REGISTRATION RIGHTS

Section 2.1 Shelf Registration.

(a) Shelf Registration. As soon as practicable but in no event more than thirty (30) days following the date of this Agreement, the Company shall use its commercially reasonable efforts to prepare and file a Shelf Registration Statement under the Securities Act covering the Registrable Securities. The Company shall use its commercially reasonable efforts to cause such Shelf Registration Statement to become effective as promptly as practicable after the date of filing of such Shelf Registration Statement (the “Filing Date”). The Company will use its commercially reasonable efforts to cause such Shelf Registration Statement filed pursuant to this Section 2.1(a) to be continuously effective under the Securities Act until the earliest of (i) all Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as contemplated in such Shelf Registration Statement, (ii) there are no longer any Registrable Securities outstanding or (iii) one year from the Effective Date (the “Effectiveness Period”). A Shelf Registration Statement filed pursuant to this Section 2.1(a) shall be on such appropriate registration form of the Commission as shall be selected by the Company. A Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (and, in the case of any prospectus contained in such Shelf Registration Statement,

4

in the light of the circumstances under which a statement is made). As soon as practicable following the date that a Shelf Registration Statement filed pursuant to this Section 2.1(a) becomes effective, but in any event within five (5) Business Days of such date, the Company shall provide the Holders with written notice of the effectiveness of a Shelf Registration Statement.    

(b) Resale Registration Opt-Out. Any Holder may deliver advance written notice (a “Resale Opt-Out Notice”) to the Company requesting that such Holder not be included in a Shelf Registration Statement filed pursuant to Section 2.1(a). Following receipt of a Resale Opt-Out Notice from a Holder, the Company shall not be required to include the Registrable Securities of such Holder in such Shelf Registration Statement.

(c) Delay Rights. Notwithstanding anything to the contrary contained herein, the Company may delay the filing of a Shelf Registration Statement required by Section 2.1(a) and may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if (i) the Company is pursuing a financing, acquisition, merger, reorganization, disposition or other similar transaction or a material event or occurrence has occurred with respect to the Company that has not been disclosed to the public and (ii) the Company determines in good faith that the disclosure of such transaction or event at such time would be detrimental to the Company or the holders of the Common Stock; provided, however, that in no event will the Company’s obligation to file a Shelf Registration Statement pursuant to Section 2.1(a) or a Selling Holder’s right to sell Registrable Securities be suspended for a period that exceeds an aggregate of sixty (60) days in any one hundred eighty (180) day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 2.2 Piggyback Registration.

(a) Participation. If (x) the Company proposes to file (A) a registration statement under the Securities Act providing for the public offering of Common Stock, for its own account or for the account of a selling stockholder (other than a Holder pursuant to this Agreement), excluding a registration statement on Form S-4 or Form S-8 promulgated under the Securities Act (or any successor forms thereto), a registration statement for the sale of Common Stock issued upon conversion of debt securities, a registration statement for sale to the public in an Underwritten Offering, or any form not available for registering the Registrable Securities for sale to the public, or (B) a prospectus supplement to an effective Shelf Registration Statement, so long as the Company is a WKSI at such time, and (y) a Holder’s Registrable Securities shall not have been included in a Registration Statement pursuant to Section 2.1(a), then the Company will notify such Holder of the proposed filing and afford such Holder an opportunity to include all or any part of the Registrable Securities then held by such Holder (the “Included Registrable Securities”) that may properly be offered on such registration statement (a “Piggyback Registration”); provided, however, that the Company may at any time withdraw or cease

5

proceeding with any such registration if it shall at the same time withdraw or cease proceeding with the registration of all other equity securities originally proposed to be registered. Each Holder of Registrable Securities agrees that the fact that such a notice has been delivered shall constitute confidential information and such Holder agrees not to disclose that such notice has been delivered or effect any public sale or distribution of Common Stock until the earlier of (i) the date that the applicable registration statement or prospectus supplement has been filed with the Commission and (ii) twenty (20) days after the date of such notice. Each Holder desiring to include in such Piggyback Registration all or part of such Registrable Securities held by such Holder that may be included in such Piggyback Registration shall, within three (3) Business Days after receipt of the above-described notice from the Company in the case of a filing of a registration statement and within two (2) Business Days after the day of receipt of the above-described notice from the Company in the case of a filing of a prospectus supplement to an effective Shelf Registration Statement with respect to a Piggyback Registration, so notify the Company in writing (such notice, a “Piggyback Notice”), and in such notice shall inform the Company of the number of Registrable Securities such Holder wishes to include in such Piggyback Registration and provide the Company with such information with respect to such Holder as shall be reasonably necessary in order to assure compliance with federal and applicable state securities Laws. If no request for inclusion from a Holder is received within the time period specified in this Section 2.2(a), such Holder shall have no further right to participate in such Piggyback Registration. .

Section 2.3 Sale Procedures. In connection with its obligations under this Article II, the Company will, as promptly as practicable:

(a) subject to Section 2.1(c), prepare and file with the Commission such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep a Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by a Shelf Registration Statement;

(b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto (other than any amendment or supplement resulting from the filing of a document incorporated by reference therein), upon request, copies of reasonably complete drafts of all such documents proposed to be filed (excluding exhibits and any document incorporated by reference therein), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing such Shelf Registration Statement or such other registration statement and the prospectus included therein or any such supplement or amendment thereto, and (ii) such number of copies of such Shelf Registration Statement or such other registration statement and the prospectus included therein and any such supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement or any other registration statement;

6

(c) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by a Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request, provided that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

(d) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the filing of a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus included therein or any amendment or supplement thereto (other than any amendment or supplement resulting from the filing of a document incorporated by reference therein), and, with respect to such Shelf Registration Statement or any other registration statement or any post-effective amendment thereto, in each case other than an Automatic Shelf Registration Statement, when the same has become effective; and (ii) the receipt of any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to such Shelf Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

(e) immediately notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus contained in a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplemental amendment thereto, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of such Shelf Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice but subject to Section 2.1(c), the Company agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(f) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning after the Effective Date of such registration statement, which earnings statement shall satisfy the provisions of Section l1(a) of the Securities Act and Rule 158 promulgated thereunder;

7

(g) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed; provided, that nothing herein shall prevent the Company from consummating a transaction in which the Common Stock ceases to be listed on a securities exchange;

(h) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(i) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the Effective Date; and

(j) if reasonably requested by a Selling Holder, (i) incorporate in a prospectus supplement or post-effective amendment such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities by such Selling Holder, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment.

Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (e) of this Section 2.3, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (e) of this Section 2.3 or until it is advised in writing by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by the Company, such Selling Holder will deliver to the Company (at the Company’s expense) all copies in its possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus and any prospectus supplement covering such Registrable Securities current at the time of receipt of such notice.

Section 2.4 Cooperation by Holders. The Company shall have no obligation to include Registrable Securities of a Holder in the Shelf Registration Statement under Article II of this Agreement if such Selling Holder has failed to timely furnish such information that the Company determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.5 Restrictions on Public Sale by Holders of Registrable Securities. In the event of an Underwritten Offering, if requested by a Managing Underwriter, each Holder of Registrable Securities hereby agrees, and shall cause any directors, officers and Affiliates of such Holder to agree, to be bound by reasonable and customary “lock up” agreements with such Managing Underwriters restricting the ability to dispose of the Common Stock, directly or indirectly, during the period requested by the Managing Underwriter; provided, however, that such period shall in no event be greater than that which applies to executive officers and directors of

8

the Company. In order to enforce the foregoing covenant, the Company shall have the right to impose stop transfer instructions with respect to the Registrable Securities and such other securities of each Holder (and the securities of every other Person subject to the foregoing restriction) until the end of such period.

Section 2.6 Expenses.

(a) Certain Definitions. “Registration Expenses” means all expenses incident to the Company’s performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration Statement pursuant to Section 2.1 or a Piggyback Registration pursuant to Section 2.2, and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and Nasdaq fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, the fees and disbursements of counsel and independent public accountants for the Company, including the expenses of any special audits or “comfort” letters required by or incident to such performance and compliance. Except as otherwise provided in Section 2.7, the Company shall not be responsible for legal fees or disbursements incurred by Holders in connection with the exercise of such Holders’ rights hereunder. In addition, the Company shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions or broker or similar commissions or fees, and transfer taxes allocable to the sale of the Registrable Securities.

(b) Expenses. The Company will pay all reasonable Registration Expenses in connection with a Shelf Registration Statement or a Piggyback Registration, whether or not any sale is made pursuant to such Shelf Registration Statement or Piggyback Registration. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.7 Indemnification.

(a) By the Company. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Holder thereunder, its directors, officers and agents and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers and agents, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading,

9

and will reimburse each such Selling Holder, its directors and officers and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or such other registration statement, or prospectus supplement, as applicable.

(b) By Each Selling Holder. Each Selling Holder agrees to, severally and not jointly, indemnify and hold harmless the Company, its directors, officers and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or prospectus supplement relating to the Registrable Securities, or any amendment or supplement thereto.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.7(c) except to the extent that the indemnifying party is materially prejudiced by such failure. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.7(c) for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, the indemnifying party shall not settle any indemnified claim without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete release from liability of, and does not contain any admission of wrong doing by, the indemnified party.

10

(d) Contribution. If the indemnification provided for in this Section 2.7 is held by a court or government agency of competent jurisdiction to be unavailable to the Company or any Selling Holder or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and of such Selling Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and each Selling Holder on the other 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 has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to indemnification or contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.7 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.8 Transfer or Assignment of Registration Rights. The right to cause the Company to register Registrable Securities granted to ▇▇▇▇▇▇▇▇ and the Munger Sellers by the Company under this Article II may be transferred or assigned by ▇▇▇▇▇▇▇▇ and the Munger Sellers, respectively, only to one or more transferee(s) or assignee(s) of such Registrable Securities that is an Affiliate of ▇▇▇▇▇▇▇▇ or the Munger Sellers, as applicable. The Company shall be given written notice prior to any such transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, and each such transferee shall assume in writing responsibility for its obligations under this Agreement.

Section 2.9 Transfer Restrictions. Without the prior written approval of the Company, no Holder shall, directly or indirectly, sell, offer or agree to sell, or otherwise transfer, or loan or pledge (other than a pledge in connection with a bona fide third party debt financing), through swap or hedging transactions, or grant any option to purchase, make any short sale or otherwise dispose of (“Transfer”) any Shares to (a) any Person whose business directly and substantially competes with the business of the Company or (b) any Person who after giving effect to such Transfer and, to the Transferring Holder’s knowledge, would own 5.0% or more of the outstanding shares of Common Stock (other than any Person entitled to file a Schedule 13G with respect to the Common Stock pursuant to Rule 13d-1(b)(1) under the Exchange Act); provided, however, that this Section 2.9 shall not apply to (A) a transfer to an Affiliate of such Holder or (B) any Transfer effected through an open market transaction in which the transferee’s identity is not known to such Holder. Any attempt to Transfer any Shares in violation of this Section 2.9 shall be null and void ab initio and no right, title or interest therein or thereto shall be Transferred to the purported Transferee. The Company will not give, and will not permit the Company’s transfer agent to give, any effect to such attempted Transfer on its records.

11
