The Initial Registration Statement shall be on Form S-3 (or such other form available to register for resale all of the Registrable Securities as a secondary offering) and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement) a “Plan of Distribution” section substantially in the form attached hereto as Annex A (which may be modified to respond to comments, if any, provided by the Commission). The Company shall notify the Investor in writing promptly upon the filing of the Initial Registration Statement. Notwithstanding the registration obligations set forth in this Section 2, in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform the Investor and use its commercially reasonable best efforts to file amendments to the Initial Registration Statement as required by the Commission, and/or (ii) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering all of the Registrable Securities permitted to be registered by the Commission, on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering. In the event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable best efforts to file with the Commission, as promptly as allowed by the Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”). The Investor shall not be named as an “underwriter” in any Registration Statement without its prior written consent.

(b)The Company shall use its commercially reasonable best efforts to cause each Registration Statement or any post-effective amendment thereto to be declared effective by the Commission as soon as practicable and, with respect to the Initial Registration Statement or the New Registration Statement, as applicable, no later than the Effectiveness Deadline, and shall use its commercially reasonable best efforts to keep each Registration Statement continuously effective under the Securities Act until the earliest of (i) such time as all of the Registrable Securities covered by such Registration Statement have been publicly sold by the Investor; (ii)

such time as all Registrable Securities covered by such Registration Statement may be sold (A) without limitations as to volume of sales, method of sale requirements or notice requirements pursuant to Rule 144 and (B) without the requirement for the Company to be in compliance with the current public information requirement under Rule 144(c)(1); or (iii) the date that is three (3) years following the Closing Date (the “Effectiveness Period”), provided, that such Effectiveness Period shall be extended for a period of time equal to the Lock-up Period (as defined in the Subscription Agreement). The Company shall, by 5:00 p.m. New York City time on the first Business Day after the Effective Date, file a final Prospectus with the Commission, as required by Rule 424(b).

(c)The Investor agrees to furnish to the Company a completed Selling Stockholder Questionnaire not more than ten (10) Business Days following the date of this Agreement. At least ten (10) Business Days prior to the first anticipated filing date of a Registration Statement for any registration under this Agreement, the Company will notify the Investor of the information the Company requires from the Investor other than the information contained in the Selling Stockholder Questionnaire, if any, which shall be completed and delivered to the Company promptly upon request and, in any event, within three (3) Business Days prior to the applicable anticipated filing date. The Investor further agrees that it shall not be entitled to be named as a selling security holder in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time, unless the Investor has returned to the Company a completed and signed Selling Stockholder Questionnaire and a response to any requests for further information as described in the previous sentence. The Investor acknowledges and agrees that the information in the Selling Stockholder Questionnaire or request for further information as described in this Section 2(c) will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement.

3.Registration Procedures.

In connection with the Company’s registration obligations hereunder, the Company shall:

(a) (i) Subject to Section 3(g), prepare and file with the Commission such amendments (including post-effective amendments) and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for its Effectiveness Period; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably practicable to any comments received from the Commission with respect to each Registration Statement or any amendment thereto; and (iv) comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement until such time as all of such Registrable Securities cease to be Registrable Securities or shall have been disposed of (subject to the terms of this Agreement) in accordance with the intended methods of disposition by the Investor as set forth in such Registration Statement as so amended or in such Prospectus as so supplemented; provided, however, that in the event the Company informs the Investor in writing that it does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Investor is required to deliver a Prospectus in connection with any disposition of Registrable Securities, the Investor shall be responsible for the delivery of the Prospectus to the

Persons to whom Investor sells any of the Registrable Securities, and the Investor agrees to dispose of Registrable Securities in compliance with the “Plan of Distribution” described in the Registration Statement and otherwise in compliance with applicable federal and state securities laws.

(b)Notify the Investor (which notice shall be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably practicable via facsimile or electronic mail: (i) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (ii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (iii) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or amendment or supplement thereto, in light of the circumstances under which they were made), not misleading.

(c)Use commercially reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as reasonably practicable.

(d)If requested by the Investor, furnish to the Investor, without charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by the Investor (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission; provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system.

(e)Prior to any resale of Registrable Securities by the Investor, use its commercially reasonable efforts to register or qualify or cooperate with the Investor in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for resale by the Investor under the securities or “blue sky” laws of such jurisdictions within the United States as the Investor reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that the Company shall not be required to qualify generally to do business in any jurisdiction where it

is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject, or file a general consent to service of process in any such jurisdiction.

(f)If requested by Investor, cooperate with Investor to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement, which certificates shall be free, to the extent permitted by the applicable Subscription Agreement and under law, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as the Investor may reasonably request.

(g)Following the occurrence of any event contemplated by Section 3(b), as promptly as reasonably practicable (taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event), prepare a supplement or amendment, including a post-effective amendment, to the affected Registration Statements or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will 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 (in the case of any Prospectus, form of prospectus or amendment or supplement thereto, in light of the circumstances under which they were made), not misleading. If the Company notifies the Investor in accordance with Section 3(b) above to suspend the use of any Prospectus until the requisite changes to such Prospectus have been made, then the Investor shall suspend use of such Prospectus. The Company will use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 3(g) to suspend the availability of a Registration Statement and Prospectus for a period not to exceed 45 calendar days (which need not be consecutive days) in any 12-month period.

(h)The Company may require the Investor to furnish to the Company a certified statement as to (i) the number of shares of Common Stock beneficially owned by the Investor and any Affiliate thereof, (ii) any Financial Industry Regulatory Authority, Inc. (“FINRA”) affiliations, (iii) any natural persons who have the power to vote or dispose of the common stock, and (iv) any other information as may be requested by the Commission, FINRA or any state securities commission.

(i)In the event the number of shares available under any Registration Statement is insufficient to cover all of the Registrable Securities required to be covered by such Registration Statement, the Company shall amend such Registration Statement (if permissible), or file with the Commission a new registration statement, so as to cover at least all Registrable Securities immediately preceding the date of the filing of such amendment or new registration statement, in each case, as soon as practicable, but in any event not later than fifteen (15) Business Days after the necessity therefor arises. The Company shall use its commercially reasonable best efforts to cause such amendment to such registration statement to become effective as soon as practicable following the filing thereof with the Commission, but in no event later than the applicable Effectiveness Deadline for such registration statement.

4.Registration Expenses. All fees and expenses incident to the Company’s performance of

or compliance with its obligations under this Agreement (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for the Investor) shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. In no event shall the Company be responsible for any underwriting, broker or similar fees or commissions of the Investor or any legal fees or other costs of the Investor. Expenses of any Registration Statement abandoned prior to the effectiveness thereof at the request of the Investor shall be borne by the Investor.

5.Indemnification.

(a)Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold harmless the Investor, its officers, directors, agents and employees , each Person who controls the Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus, form of prospectus or amendment or supplement thereto (it being understood that the Investor has approved Annex A hereto for this purpose), or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or amendment or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding the Investor furnished in writing to the Company by the Investor, or to the extent that such information relates to the Investor or its proposed method of distribution of Registrable Securities and was reviewed and approved in writing by the Investor expressly for use in the Registration Statement, Prospectus, form of prospectus or in any amendment or supplement thereto (it being understood that the Investor has approved Annex A hereto for this purpose) or (B) in the case of an occurrence of an event of the type specified in Section 3(b), related to the use by the Investor of an outdated or defective Prospectus after the Company has notified the Investor in writing that the Prospectus is outdated or defective and prior to the receipt by the Investor of the Advice contemplated and defined in Section 6(c) below, or (C) any such Losses arise out of the Investor’s (or any other indemnified Person’s) failure to send or give a copy of the Prospectus or supplement (as then amended or supplemented), if required pursuant to Rule 172 under the Securities Act (or any successor rule), to the Persons asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person, if such statement or omission was corrected in such Prospectus or supplement. The Company shall notify the Investor promptly of the institution, threat or assertion of any Proceeding arising from

or in connection with the transactions contemplated by this Agreement of which the Company is aware.

(b)Indemnification by the Investor. The Investor shall and notwithstanding any termination of this Agreement, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based solely upon (i) the Investor’s failure to comply with the prospectus delivery requirements of the Securities Act, or (ii) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus, form of prospectus or amendment or supplement thereto, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or amendment or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that (A) such untrue statements or omissions are based upon information regarding the Investor furnished in writing to the Company by the Investor expressly for use therein or (B) such information relates to the Investor and was reviewed and approved in writing by the Investor expressly for use in any Registration Statement, Prospectus, form of prospectus or amendment or supplement thereto (it being understood that the Investor has approved Annex A hereto for this purpose), or (C) in the case of an occurrence of an event of the type specified in Section 3(b), such Losses are related to the use by the Investor of an outdated or defective Prospectus after the Company has notified the Investor in writing that the Prospectus is outdated or defective and prior to the receipt by the Investor of the Advice contemplated in Section 6(c). In no event shall the liability of the Investor be greater in amount than the dollar amount of the net proceeds received by the Investor upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c)Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable fees and expenses incurred in connection with the defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; (ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party,

and such Indemnified Party shall have been advised by counsel that a conflict of interest would exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party); provided, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding and such settlement does not include any non-monetary limitation on the actions of any Indemnified Party or any of its affiliates or any admission of fault or liability on behalf of any such Indemnified Party. Notwithstanding any other provision of this Section 5(c), if an Indemnified Party withholds its consent to a bona fide settlement offer, where but for such action the Indemnifying Party could have settled a Proceeding, the Indemnifying Party will be required to indemnify the Indemnified Party only up to the amount of the bona fide settlement offer for which the Indemnifying Party could have settled such Proceeding.

Subject to the terms of this Agreement, all fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section 5) shall be paid to the Indemnified Party, as incurred, within 20 Business Days of written notice thereof to the Indemnifying Party; provided, that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified Party is finally judicially determined to not be entitled to indemnification hereunder. The failure to deliver written notice to the Indemnifying Party within a reasonable time of the commencement of any such action shall not relieve such Indemnifying Party of any liability to the Indemnified Party under this Section 5, except to the extent that the Indemnifying Party is materially and adversely prejudiced in its ability to defend such action.

(d)Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each 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 Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or

expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 5 was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), (A) the Investor shall not be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by the Investor from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that the Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (B) no contribution will be made under circumstances where the maker of such contribution would not have been required to indemnify the Indemnified Party under the fault standards set forth in this Section 5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section 5 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties and are not in diminution or limitation of the indemnification provisions under the Subscription Agreement.

6.Miscellaneous.

(a)Remedies. Subject to the limitations set forth elsewhere in this Agreement, in the event of a breach by the Company or by the Investor of any of their obligations under this Agreement, the Investor or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and the Investor agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b)Compliance. The Investor covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it (unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant to the Registration Statement, and shall sell the Registrable Securities only in accordance with a method of distribution described in the Registration Statement.

(c)Discontinued Disposition. By its acquisition of Registrable Securities, the Investor agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(b), the Investor will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its commercially reasonable best efforts to ensure that the

use of the Prospectus may be resumed as promptly as is practicable. The Company may provide appropriate stop orders to enforce the provisions of this paragraph.

(d)Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Investor, and any amendment to any provision of this Agreement made in accordance with this Section 6(d) shall be binding.

(e)Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as set forth in the applicable Subscription Agreement.

(f)Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of the Investor. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. The Company may not assign its rights (except by merger or in connection with another entity acquiring all or substantially all of the Company’s assets) or obligations hereunder without the prior written consent of the Investor. The Investor may assign its respective rights with respect to any or all of its Shares hereunder in the manner and to the Persons as permitted under the Subscription Agreement; provided that (i) the Investor agrees in writing with the transferee or assignee to assign such rights and related obligations under this Agreement, and for the transferee or assignee to assume such obligations, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (iii) at or before the time the Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein, and (iv) the transferee is an “accredited investor,” as that term is defined in Rule 501 of Regulation D.

(g)Execution and Counterparts. This Agreement may be executed in two or more counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same Agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature were the original thereof.

(i)Cumulative Remedies. Except as provided herein, the remedies provided herein are cumulative and not exclusive of any other remedies provided by law.

(j)Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

(k)Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. Any references to paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

Annex A

PLAN OF DISTRIBUTION

The Investor and any of its assignees and successors-in-interest (collectively the “Selling Stockholders”) may, from time to time, sell any or all of their shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling shares:

●	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

●	block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

●	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

●	an exchange distribution in accordance with the rules of the applicable exchange;

●	privately negotiated transactions;

●	broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share;

●	a combination of any such methods of sale; and

●	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell shares under Rule 144 under the Securities Act of 1933, as amended, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

The Selling Stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We are required to pay all fees and expenses incident to the registration of the shares, but not including certain fees and disbursements of counsel to the Selling Stockholders; in addition, a Selling Stockholder will pay all underwriting discounts and selling commissions, if any. We have agreed to indemnify the Selling Stockholders against certain losses, claims, damages and

liabilities, including liabilities under the Securities Act. We may be indemnified by the Selling Stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished to us by the Selling Stockholder specifically for use in this prospectus, in accordance with the registration rights agreement, or we may be entitled to contribution.

To the extent required, we will amend or supplement this prospectus to disclose material arrangements regarding the plan of distribution.

To comply with the securities laws of certain jurisdictions, registered or licensed brokers or dealers may need to offer or sell the shares offered by this prospectus. The applicable rules and regulations under the Securities Exchange Act of 1934, as amended, may limit any person engaged in a distribution of the shares of common stock covered by this prospectus in its ability to engage in market activities with respect to such shares. A Selling Stockholder, for example, will be subject to applicable provisions of the Exchange Act and the rules and regulations under it, including, without limitation, Regulation M of the Exchange Act, which provisions may limit the timing of purchases and sales of any shares of common stock by that Selling Stockholder. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.
