1.  Issuance and Sale of Placement Shares . The Company agrees that, from time to time during the term of this Agreement, on the terms and subject to the conditions set forth herein, and in its sole discretion, it may issue and sell through HCW, shares (the “ Placement Shares ”) of the Company’s common stock, $0.0075 par value per share (the “ Common Stock ”); provided however, that in no event shall the Company issue or sell through HCW such number of Placement Shares that (a) exceeds the number of shares or dollar amount of Common Stock registered on the effective Registration Statement (as defined below) pursuant to which the offering is being made or (b) exceeds the number of shares or dollar amount registered on the Prospectus Supplement (as defined below) (the lesser of (a) or (b), the “ Maximum Amount ”). Notwithstanding anything to the contrary contained herein, the parties hereto agree that compliance with the limitations set forth in this Section  1 on the number of Placement Shares issued and sold under this Agreement shall be the sole responsibility of the Company and that HCW shall have no obligation in connection with such compliance. The issuance and sale of Placement Shares through HCW will be effected pursuant to the Registration Statement (as defined below), although nothing in this Agreement shall be construed as requiring the Company to use the Registration Statement to issue any Placement Shares.

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (the “ Securities Act ”), with the Securities and Exchange Commission (the “ Commission ”), a registration statement on Form S-3 (File No. 333-223493), including a base prospectus, relating to certain securities, including the Common Stock to be issued from time to time by the Company, and which incorporates by reference documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), and the rules and regulations thereunder. The Company has prepared a prospectus supplement to the base prospectus included as part of the registration statement, which prospectus supplement relates to the Placement Shares to be issued from time to time by the Company pursuant to this Agreement (the “ Prospectus Supplement ”). The Company will furnish to HCW, for use by HCW, copies of the base prospectus included as part of such registration statement, as supplemented by the

Prospectus Supplement, relating to the Placement Shares to be issued from time to time by the Company. The Company may file, if necessary, one or more additional registration statements from time to time that will contain a base prospectus and related prospectus or prospectus supplement, if applicable (which shall be a Prospectus Supplement), with respect to the Placement Shares. Except where the context otherwise requires, such registration statement(s), and any post-effective amendment thereto, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part of such registration statement(s) pursuant to Rule 430B of the Securities Act, is herein called the “ Registration Statement .” The base prospectus or base prospectuses, including all documents incorporated or deemed incorporated therein by reference, included in the Registration Statement, as it may be supplemented by the Prospectus Supplement, in the form in which such prospectus or prospectuses and/or Prospectus Supplement have most recently been filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act, together with any then issued “issuer free writing prospectus(es),” as defined in Rule 433 promulgated under the Securities Act, relating to the Placement Shares that (i) is required to be filed with the Commission by the Company or (ii) is exempt from filing pursuant to Rule 433(d)(5)(1), in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 533(g), is herein called the “ Prospectus .”

Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include any documents deemed incorporated by reference therein (pursuant to the Securities Act or the Exchange Act) (the “ Incorporated Documents ”), and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include the filing after the execution hereof of any Incorporated Document. For purposes of this Agreement, all references to the Registration Statement, to the Prospectus, to the Incorporated Documents or to any amendment or supplement thereto shall be deemed to include the most recent copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval System, or if applicable, the Interactive Data Electronic Application system when used by the Commission (collectively, “ EDGAR ”).

2.  Placements . Each time that the Company wishes to issue and sell Placement Shares hereunder (each, a “ Placement ”), it will notify HCW by email notice from a person identified on Schedule 2 (or other method mutually agreed to in writing by the parties) (a “ Placement Notice ”) containing the parameters in accordance with which it desires the Placement Shares to be sold, which shall at a minimum include the number or dollar value of Placement Shares to be issued, the time period during which sales are requested to be made, any limitation on the number of Placement Shares that may be sold in any one Trading Day (as defined in Section  3 ) and any minimum price below which sales may not be made, a form of which containing such minimum sales parameters necessary is attached hereto as Schedule 1 .

3.  Sale of Placement Shares by HCW .

(a) Subject to the terms and conditions herein set forth, upon the Company’s delivery of a Placement Notice, and unless the sale of the Placement Shares described therein has been declined, suspended, or otherwise terminated in accordance with the terms of this Agreement, HCW, for the period specified in the Placement Notice, will use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Global Market (the “ Exchange ”) to sell such Placement Shares up to the amount specified, and otherwise in accordance with the terms of such Placement Notice.

This indemnity agreement will be in addition to any liability that the Company might otherwise have.

- 24 -

(b)  HCW Indemnification . HCW agrees to indemnify and hold harmless the Company and its directors, officers, employees and agents of the Company and each person, if any, who (i) controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or (ii) is controlled by or is under common control with the Company (each, a “ Company Affiliate ”) from and against any and all losses, claims, liabilities, expenses and damages (including, but not limited to, any and all reasonably investigative, legal and other expenses incurred in connection with, and any and all amounts paid in settlement (in accordance with Section  9(a) ) of, any action, suit or proceeding between any indemnified party and any third party, or any claim asserted by a third party), as and when incurred, to which the Company, or any Company Affiliate, may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based, directly or indirectly, on untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information relating to HCW and furnished to the Company in writing by HCW expressly for use therein.

(c)  Procedure . Any party that proposes to assert the right to be indemnified under this Section  9 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section  9 , notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this Section  9 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section  9 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party or to the extent the indemnifying party has been damaged or prejudiced thereby. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict of interest exists (based on advice of counsel to the

- 25 -

indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees and documented out-of-pocket disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such reasonable fees and documented out-of-pocket disbursements and other charges will be promptly reimbursed by the indemnifying party following the receipt of reasonably detailed documentation with respect to the incurrence of such fees, disbursements and other charges. So long as the indemnifying party is conducting the defense of the claim for liability in accordance with this Section, the indemnified party will reasonably cooperate with the indemnifying party’s defense of such claim. An indemnifying party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section  9 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding and (ii) does not include any statement or admission as to fault, culpability or a failure to act on the part of any indemnified party.

(d)  Contribution . In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section  9 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or HCW, the Company and HCW will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than HCW, such as persons who control the Company within the meaning of the Securities Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and HCW may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and HCW on the other hand. The relative benefits received by the Company on the one hand and HCW on the other hand shall be deemed to be in the same proportion as the total Net Proceeds from the sale of the Placement Shares (before deducting expenses) received by the Company bear to the total compensation received by HCW (before deducting expenses) from the sale of Placement Shares on behalf of the Company. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and HCW, on the other, with respect to the statements or omission that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well

- 26 -

as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or HCW, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and HCW agree that it would not be just and equitable if contributions pursuant to this Section  9(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section  9(d) shall be deemed to include, for the purpose of this Section  9(d) , any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with Section  9(c) hereof. Notwithstanding the foregoing provisions of this Section  9(d) , HCW shall not be required to contribute any amount in excess of the commissions received by it under this Agreement and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section  9(d) , any person who controls a party to this Agreement within the meaning of the Securities Act, and any officers, directors, partners, employees or agents of HCW, will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section  9(d) , will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section  9(d) except to the extent that the failure to so notify such other party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section  9(c) hereof, no party will be liable for contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section  9(c) hereof.

10.  Representations and Agreements to Survive Delivery . The indemnity and contribution agreements contained in Section  9 of this Agreement and all representations and warranties of the Company herein or in certificates delivered pursuant hereto shall survive, as of their respective dates, regardless of (i) any investigation made by or on behalf of HCW, any controlling persons, or the Company (or any of their respective officers, directors or controlling persons), (ii) delivery and acceptance of the Placement Shares and payment therefor or (iii) any termination of this Agreement.

11.  Termination.

(a) HCW shall have the right by giving written notice as hereinafter specified at any time to terminate this Agreement if (i) since the date of this Agreement, any Material Adverse Change, or any development that would reasonably be expected to result in a Material Adverse Change has occurred that, in the reasonable judgment of HCW, may materially impair the ability

- 27 -

of HCW to sell the Placement Shares hereunder, (ii) the Company shall have failed, refused or been unable to perform any agreement on its part to be performed hereunder (through no fault of HCW); provided, however, in the case of any failure of the Company to deliver (or cause another person to deliver) any certification, opinion, or letter required under Sections 7(m) , 7(n) , or 7(o) , HCW’s right to terminate shall not arise unless such failure to deliver (or cause to be delivered) continues for more than thirty (30) days from the date such delivery was required; (iii) any other condition of HCW’s obligations hereunder is not fulfilled; or (iv), any suspension of trading in the Common Stock shall have occurred. Any such termination shall be without liability of any party to any other party except that the provisions of Section  7(g) (Expenses), Section  9 (Indemnification and Contribution), Section  10 (Representations and Agreements to Survive Delivery), Section  16 (Applicable Law; Consent to Jurisdiction) and Section  17 (Waiver of Jury Trial) hereof shall remain in full force and effect notwithstanding such termination. If HCW elects to terminate this Agreement as provided in this Section  11(a) , HCW shall provide the required written notice as specified in Section  12 (Notices).

(b) The Company shall have the right, by giving five (5) days’ notice as hereinafter specified to terminate this Agreement in its sole discretion at any time after the date of this Agreement .

(c) HCW shall have the right, by giving five (5) days’ notice as hereinafter specified to terminate this Agreement in its sole discretion at any time after the date of this Agreement . Any such termination shall be without liability of any party to any other party except that the provisions of Section 7(g), Section 9, Section 10, Section 16 and Section 17 hereof shall remain in full force and effect notwithstanding such termination.

(d) Unless earlier terminated pursuant to this Section  11 , this Agreement shall automatically terminate upon the issuance and sale of all of the Placement Shares through HCW on the terms and subject to the conditions set forth herein; provided that the provisions of Section  7(g) , Section  9 , Section  10 , Section  16 and Section  17 hereof shall remain in full force and effect notwithstanding such termination.

(e) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 11(a) , (b) , (c) , or (d)  above or otherwise by mutual agreement of the parties; provided, however, that any such termination by mutual agreement shall in all cases be deemed to provide that Section  7(g) , Section  9 , Section  10 , Section  16 and Section  17 shall remain in full force and effect.

(f) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided, however, that such termination shall not be effective until the close of business on the date of receipt of such notice by HCW or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Placement Shares, such Placement Shares shall settle in accordance with the provisions of this Agreement.
