(b) Upon receipt of the Registration Request, the Company will, as promptly as practicable thereafter but in any event within 45 days of receipt of the Registration Request, file (unless an applicable shelf registration statement has already been filed) and use its commercially reasonable efforts to effect such registration on an appropriate and available form of registration statement (including, if available, an automatic registration statement for a “well-known seasoned issuer” as defined under the Securities Act, and including, without limitation, to cause such registration statement to be declared effective under the Securities Act as promptly as practicable after the filing thereof, and filing post-effective amendments, appropriate qualifications under applicable “Blue Sky” or other state securities laws, and appropriate compliance with the Securities Act) to permit or facilitate the sale and distribution of all or such portion of such Shares as are specified in such request. No securities other than Shares held by Purchaser shall be included under any such registration statement without the written consent of Purchaser (not to be unreasonably withheld or delayed); provided that in no event shall any such additional securities take priority over the sale of Shares held by Purchaser in any offering thereunder.

(c) If the Company provides notice to Purchaser in a certificate signed by the Chief Executive Officer or Chief Financial Officer of the Company that (i) in the good faith judgment of the Board of Directors of the Company, the filing of a registration statement covering the Shares at such time would be materially detrimental to the Company, and the reason for such judgment (which shall not be stated in such notice) is because such filing (A) would materially interfere with a bona fide and imminent material financing of the Company or imminent material transaction under consideration by the Company or (B) would require the disclosure of information that has not been, and is not otherwise required to be, disclosed to the public, the premature disclosure of which would be materially detrimental to the Company and (ii) the Board of Directors of the Company concluded, as a result, that it is in the best interests of the Company to defer the filing (or, in the case of clause (B), suspend the use) of the registration statement specified in Section 6.1(b) above at such time, then the Company shall have the right to defer such filing (and, in the case of clause (B), suspend the use) of the registration statement for a reasonable period not to exceed (x) 60 days in any case and (y) 105 days in the aggregate in any twelve-month period. If the Company so postpones effecting a registration (or suspends the ability to use a shelf registration), Purchaser shall be entitled to withdraw its Registration Request, in which case such Registration Request shall not count for purposes of the limitation set forth in Section 6.1(a).

(d) In addition to the foregoing, in the event Purchaser shall in good faith determine, based on the advice of reputable U.S. securities legal counsel (and after consultation with the Company and its reputable U.S. securities legal counsel), that Purchaser might be deemed an “affiliate” of the Company under the U.S. federal securities laws as a result of an increase in its beneficial ownership percentage of the Company (except as a result of its purchase or acquisition of shares of Common Stock other than from the Company), upon the request of Purchaser, the Company will, as promptly as practicable thereafter but in any event within 45 days of receipt of such request, file and use its commercially reasonable efforts to qualify for registration on a Form S-3 registration statement (including, if available, an automatic registration statement for a “well-known seasoned issuer”

as defined under the Securities Act) or any comparable or successor form (“Short-Form Registration”), which shall constitute a “shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis of, the Shares, pursuant to Rule 415 under the Securities Act, to permit the distribution of the Shares in accordance with the methods of distribution elected by Purchaser, including by means of an underwritten offering or block sale that could be effected pursuant to a Registration Request. Upon filing a Short-Form Registration, the Company shall use its commercially reasonable efforts to keep such Short-Form Registration effective with the SEC at all times and any Short-Form Registration shall be re-filed upon its expiration, and the Company shall cooperate in any shelf take-down by amending or supplementing the prospectus related to such Short-Form Registration as may be reasonably requested by Purchaser or as otherwise required, until the disposition of all of Purchaser’s Shares is complete or the date that is 90 days after the date Purchaser ceases to be deemed an “affiliate” of the Company (as determined in good faith by Purchaser, based on the advice of reputable U.S. securities legal counsel (and after consultation with the Company and its reputable U.S. securities legal counsel)).

6.2 Company Registration.

(a) After the Transfer Restriction Period shall have expired, if the Company shall determine to register any of its Common Stock for its own account, other than a registration relating solely to employee benefit plans, a registration relating to the offer and sale of convertible or other debt securities, a registration relating to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will (i) promptly give written notice of the proposed registration to Purchaser and (ii) use its commercially reasonable efforts to include in such registration (and any related qualification under “Blue Sky” laws or other compliance), except as set forth in Section 6.2(b) below, and in any underwriting involved therein, all of such Shares as are specified in a written request made by Purchaser received by the Company within ten Trading Days after such written notice from the Company is mailed or delivered. Such written request may specify that all or a part of the Shares are requested to be registered.

(b) If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise Purchaser as a part of the written notice given pursuant to Section 6.2(a)(i). In such event, the right of Purchaser to registration pursuant to this Section 6.2(b) shall be conditioned upon Purchaser’s participation in such underwriting and the inclusion of the Shares in the underwriting to the extent provided herein. If Purchaser proposes to distribute its securities through such underwriting, Purchaser shall (together with the Company) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company. Notwithstanding any other provision of this Section 6.2, if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares of Common Stock to be underwritten, the underwriters may (subject to the limitations set forth below) exclude all Shares from, or limit the number of Shares to be included in, the registration and underwriting. The Company shall so advise all holders of securities requesting registration, and the number of shares of Common Stock that are entitled to be included in the registration and underwriting shall be allocated, as follows: (i) first, to the Company for shares of Common Stock being sold for its own account and (ii) second, to Purchaser requesting

to include the Shares in such registration statement. If Purchaser requests inclusion in such registration but does not agree to the terms of any such underwriting, Purchaser shall also be excluded therefrom by written notice from the Company or the underwriter. The Shares so excluded shall also be withdrawn from such underwriting. Any Shares excluded or withdrawn from such underwriting shall be withdrawn from such registration.

(c) The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 6.2 prior to the effectiveness of such registration whether or not Purchaser has elected to include Shares in such registration. Purchaser shall have the right to withdraw all or part of the Shares from such registration.

(d) No registration pursuant to this Section 6.2 shall count towards registrations required pursuant to Section 6.1.

6.3 Expenses of Registration. Except as otherwise provided below, the Company and Purchaser shall pay equally all out-of-pocket expenses (a) incident to the Company’s performance of or compliance with its obligations under this Article VI, including, without limitation, (i) all registration, filing and listing fees, (ii) printing expenses and (iii) fees and disbursements of counsel for the Company and all independent certified public accountants (including, without limitation, the expenses of any “comfort” letters) and (b) of Purchaser in connection with the registration and sale of Shares under this Article VI (including, without limitation, reasonable out-of-pocket fees and disbursements of one outside counsel (together with appropriate local counsel) for Purchaser). Notwithstanding the forgoing, (w) the Company shall pay its own internal expenses, (x) Purchaser shall pay its own internal expenses, (y) Purchaser shall pay all underwriting discounts and any other selling commissions relating to Shares sold by it, and (z) in connection with the registration and sale of Shares by Purchaser under Section 6.2, the Company shall pay all expenses except the expenses set forth in clauses (x) and (y) above and fees and disbursements of counsel for Purchaser.

6.4 Registration Procedures. In the case of a registration effected by the Company at the request of Purchaser, the Company will advise Purchaser in writing as to the initiation of each registration and as to the completion thereof. The Company will use its commercially reasonable efforts to:

(a) Keep such registration effective (i) in the case of a shelf registration statement, in accordance with Section 6.1(d), or (ii) in all other cases, for a period ending on the earlier of the date which is 120 days from the effective date of the registration statement or such time as Purchaser has completed the distribution and actual sale of all Shares described in the registration statement relating thereto (plus such additional time thereafter equal to the period of any suspension of an effective registration statement pursuant to Section 6.1(c) above and as may be customarily required by the underwriters pursuant to the underwriting agreement);

(b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in Section 6.4(a)

above, including, without limitation, to promptly include in a prospectus supplement or post-effective amendment such information as may reasonably be requested in order to permit the intended method of distribution of Shares (provided that before filing a registration statement or prospectus, or any amendments or supplements thereto, the Company shall furnish to Purchaser, Purchaser’s counsel and the managing underwriters, if any, copies of all such documents proposed to be filed (which documents will be subject to the reasonable review and comment of such counsel), and such other documents reasonably requested by such counsel (including, without limitation, any comment letter from the SEC));

(c) Furnish such number of prospectuses, including any preliminary prospectuses, and other documents incident thereto, including any amendment of or supplement to the prospectus, as Purchaser or underwriters from time to time may reasonably request;

(d) Register and qualify the securities covered by such registration statement under such other securities or “Blue Sky” laws of such jurisdiction as shall be reasonably requested by Purchaser; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

(e) Notify Purchaser (i) of the happening of any event as a result of which such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading (or as a result of which the prospectus that is part of such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading), and following such event as promptly as practicable prepare, file with the SEC (if required) and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such registration statement and prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such registration statement and prospectus shall 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 (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading, (ii) when a prospectus or any supplement or post-effective amendment has been filed, and, with respect to a registration statement or amendment thereto, when the same has become effective, (iii) of any request by the SEC or any other governmental authority for amendments or supplements to a registration statement or related prospectus or for additional information, or (iv) of the issuance by the SEC of any stop order suspending the effectiveness of a registration statement or the initiation of any proceedings for that purpose (and the Company shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement at the reasonably earliest practical date);

(f) Make available, upon reasonable prior notice and during normal business hours, at the headquarters offices of the Company, for inspection by Purchaser, any underwriter participating in any disposition pursuant to a registration hereof and any attorney, accountant or other agent retained by Purchaser or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company;

(g) Instruct the Company’s independent public accountants (and where applicable, provide such assistance and information as required) to be available to discuss with Purchaser and underwriters, in connection with an underwritten offering and in a reasonable and customary fashion, the audit reports and interim financial information procedures as well as general information concerning the relationship and review of the Company's financial statements;

(h) Cooperate and assist in any filings required to be made with the Financial Industry Regulatory Authority and in the performance of any due diligence investigation by any underwriter in an underwritten offering; and

(i) Upon the request by Purchaser, if such Purchaser intends to undertake a block trade or an underwritten offering of Shares, enter into customary agreements (including without limitation, an underwriting agreement in customary form that requires indemnification by the Company on terms customary for issuers under underwriting agreements and requires of the Company delivery (i) by the Company’s independent accountants of comfort letters and (ii) by counsel for the Company of legal opinions, in each case in customary form and covering such matters of the type customarily covered by comfort letters and legal opinions, respectively, to underwriters in connection with public offerings) and take such other actions (including, without limitation, making senior management of the Company available to participate on a reasonable and customary basis in road show presentations and in due diligence presentations, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by Purchaser or any such underwriter) as are reasonably required in order to expedite or facilitate the disposition of the Shares included in the registration statement. If any offering of Shares in a registration pursuant to Section 6.1 is an underwritten offering, Purchaser shall have the right to select the investment banker or investment bankers and managers to administer the offering, subject to approval by the Company (not to be unreasonably withheld or delayed). The Company shall have the right to select the investment banker or investment bankers and managers to administer any offering pursuant to Section 6.2.

Purchaser agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by Purchaser to the Company as a result of which any prospectus relating to such registration contains or would contain an untrue statement of a material fact regarding Purchaser or Purchaser’s intended method of disposition of such Shares or omits to state any material fact regarding Purchaser or Purchaser’s intended method of disposition of such Shares necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so that such prospectus shall not contain, with respect to Purchaser or the disposition of such Shares, an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

6.5 Indemnification.

(a) To the fullest extent permitted by law, the Company shall indemnify and hold harmless Purchaser, each of its officers, directors, legal counsel and accountants and each person controlling Purchaser within the meaning of Section 15 of the Securities Act, each holder of Shares with respect to which registration, qualification or compliance has been effected pursuant to this Article VI, and each underwriter, if any, and each person who controls within the meaning of Section 15 of the Securities Act any such holder or underwriter against all expenses, claims, losses, damages and liabilities (or actions, proceedings or settlements in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any registration statement, any prospectus included in the registration statement, any issuer free writing prospectus (as defined in Rule 433 of the Securities Act), any issuer information (as defined in Rule 433 of the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any other document incident to any such registration, qualification or compliance prepared by or on behalf of the Company or used or referred to by the Company, (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation (or alleged violation) by the Company of the Securities Act, any state securities laws or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any offering covered by such registration, qualification or compliance, and the Company will reimburse Purchaser, each of its officers, directors, partners, legal counsel and accountants and each person controlling Purchaser, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, loss, damage, liability or action; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or action arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by Purchaser, any of Purchaser’s officers, directors, legal counsel or accountants, any person controlling Purchaser, such underwriter acting for Purchaser or any person who controls any such underwriter, and stated to be specifically for use therein; and provided, further that, the indemnity agreement contained in this Section 6.5(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (not to be unreasonably withheld or delayed). Such indemnity (A) shall remain in full force and effect regardless of any investigation made by or on behalf of any such indemnitee and shall survive the transfer of the Shares and (B) is in addition to any liability that the Company may otherwise have.

(b) To the extent permitted by law, Purchaser will indemnify and hold harmless the Company, each of its directors, officers, legal counsel and accountants, and each person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any prospectus, offering circular or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification or compliance, or (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and such directors, officers, legal counsel and accountants, persons, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim,

loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by Purchaser and stated to be specifically for use therein; provided, however, that the obligations of Purchaser hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages or liabilities (or actions in respect thereof) if such settlement is effected without the consent of Purchaser (not to be unreasonably withheld or delayed).

(c) Each party entitled to indemnification under this Section 6.5 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (not to be unreasonably withheld or delayed), and the Indemnified Party may participate in such defense at such party’s expense (provided that the Indemnified Party shall have the right to employ separate counsel and participate, at the Indemnifying Party’s expense, in the defense conducted by the Indemnifying Party and its counsel, if in the Indemnified Party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claims, provided further that the Indemnifying Party shall not, in connection with any one claim or separate but substantially similar or related claims in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one firm of attorneys (together with appropriate local counsel) at any time for all of the Indemnified Parties); and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 6.5 to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

(d) If the indemnification provided for in this Section 6.5 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the

Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity that was not guilty of such fraudulent misrepresentation. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6.5(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 6.5(d).

(e) Notwithstanding anything to the contrary contained in this Agreement, Purchaser shall not be required to indemnify or contribute any amount in excess of the amount by which the net proceeds received by Purchaser from the sale of Shares in the applicable offering exceeds the amount of any damages that Purchaser has otherwise been required to pay by reason of the applicable untrue or alleged untrue statement or omission or alleged omission.

6.6 Termination of Registration Rights. The right of Purchaser to request registration pursuant to (i) Section 6.1(a) or Section 6.2 shall terminate on the date Purchaser ceases to own at least 2,000,000 Shares unless extended as mutually determined by the Company and Purchaser, and (ii) Section 6.1(d), if ever applicable, shall terminate on the date that is 90 days after the date Purchaser (as determined pursuant to Section 6.1(d)) ceases to be deemed an “affiliate” of the Company. For the avoidance of doubt, Section 6.5 and any unsatisfied obligations under Section 6.3 shall survive such termination.

6.7 Furnishing of Information. As long as Purchaser owns Shares, the Company covenants to file all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act in order to allow Purchaser to satisfy the requirements of Rule 144. As long as Purchaser owns Shares, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to Purchaser and make publicly available in accordance with Rule 144(c) such information as is required for Purchaser to sell the Shares under Rule 144. The Company further covenants that it will take such further action as Purchaser may reasonably request, to the extent required from time to time to enable Purchaser to sell such Shares without registration under the Securities Act within the requirements of the exemption provided by Rule 144.

10.12 No Waiver.
