This COMMON STOCK PURCHASE AGREEMENT, made and entered into on this 10^th day of May, 2011 (this “Agreement”), by and between Azimuth Opportunity Ltd., an international business company incorporated under the laws of the British Virgin Islands (the “Investor”), and Omeros Corporation, a corporation organized and existing under the laws of the State of Washington (the “Company”). Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in Annex A hereto.

RECITALS

WHEREAS, the parties desire that, upon the terms and subject to the conditions contained herein, the Company may issue and sell to the Investor and the Investor shall thereupon purchase from the Company up to $40,000,000 of newly issued shares of the Company’s common stock, $0.01 par value (“Common Stock”), subject, in all cases, to the Trading Market Limit (except as expressly provided in Section 2.13); and

WHEREAS, the offer and sale of the shares of Common Stock hereunder have been registered by the Company in the Registration Statement, which has been declared effective by order of the Commission under the Securities Act;

NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby agree as follows:

ARTICLE I

PURCHASE AND SALE OF COMMON STOCK

Section 1.1 Purchase and Sale of Stock. Upon the terms and subject to the conditions of this Agreement, during the Investment Period the Company in its discretion may issue and sell to the Investor up to $40,000,000 (the “Total Commitment”) of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock (subject in all cases to the Trading Market Limit (except as expressly provided in Section 2.13), the “Aggregate Limit”), by (i) the delivery to the Investor of not more than 24 separate Fixed Request Notices (unless the Investor and the Company mutually agree that a different number of Fixed Request Notices may be delivered) as provided in Article II hereof and (ii) the exercise by the Investor of Optional Amounts, which the Company may in its discretion grant to the Investor and which may be exercised by the Investor, in whole or in part, as provided in Article II hereof. The aggregate of all Fixed Request Amounts and Optional Amount Dollar Amounts shall not exceed the Aggregate Limit.

Section 1.2 Effective Date; Settlement Dates. This Agreement shall become effective and binding upon delivery of counterpart signature pages of this Agreement executed by each of the parties hereto, and by delivery of an opinion of counsel and a certificate of the Company as provided in Section 6.1 hereof, to the offices of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, at 4:00 p.m., New York time, on the Effective Date. In consideration of and in express reliance upon the representations, warranties and covenants, and otherwise upon the terms and subject to the conditions, of this Agreement, from and after the Effective Date and during the Investment Period (i) the Company shall issue and sell to the

Investor, and the Investor agrees to purchase from the Company, the Shares in respect of each Fixed Request and (ii) the Investor may in its discretion elect to purchase Shares in respect of each Optional Amount. The issuance and sale of Shares to the Investor pursuant to any Fixed Request or Optional Amount shall occur on the applicable Settlement Date in accordance with Sections 2.7 and 2.9 (or on such Trading Day in accordance with Section 2.8, as applicable), provided in each case that all of the conditions precedent thereto set forth in Article VI theretofore shall have been fulfilled or (to the extent permitted by applicable law) waived.

Section 1.3 The Shares. The Company has or will have duly authorized and reserved for issuance, and covenants to continue to so reserve once reserved for issuance, free of all preemptive and other similar rights, at all times during the Investment Period, the requisite aggregate number of authorized but unissued shares of its Common Stock to timely effect the issuance, sale and delivery in full to the Investor of all Shares to be issued in respect of all Fixed Requests and Optional Amounts under this Agreement, in any case prior to the issuance to the Investor of such Shares.

Section 1.4 Current Report; Prospectus Supplement. As soon as practicable, but in any event not later than 5:30 p.m. (New York time) on the first Trading Day immediately following the Effective Date, the Company shall file with the Commission (i) a report on Form 8-K relating to the transactions contemplated by, and describing the material terms and conditions of, this Agreement (the “Current Report”), and (ii) a Prospectus Supplement pursuant to Rule 424(b) under the Securities Act specifically relating to the transactions contemplated by, and describing the material terms and conditions of, this Agreement, containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430B under the Securities Act, and disclosing all information relating to the transactions contemplated hereby required to be disclosed in the Registration Statement and the Prospectus as of the Effective Date, including, without limitation, information required to be disclosed in the section captioned “Plan of Distribution” in the Prospectus. The Current Report shall include a copy of this Agreement as an exhibit and shall be incorporated by reference in the Registration Statement and the Prospectus. The Company heretofore has provided the Investor a reasonable opportunity to comment on a draft of such Current Report and Prospectus Supplement and has given due consideration to such comments. Pursuant to Section 5.9 and subject to the provisions of Section 5.8, on the first Trading Day immediately following the last Trading Day of each Pricing Period, the Company shall file with the Commission a Prospectus Supplement pursuant to Rule 424(b) under the Securities Act disclosing the total number of Shares to be issued and sold to the Investor thereunder, the total purchase price therefor and the net proceeds to be received by the Company therefrom.

Section 1.5 Termination of Prior Agreements. Contemporaneously with the entry into this Agreement, and effective as of the Effective Date, both of (i) the Common Stock Purchase Agreement dated July 28, 2010, by and between the Investor and the Company and (ii) the Registration Rights Agreement dated July 28, 2010 by and between the Investor and the Company shall be terminated and be of no further force and effect.

ARTICLE II

FIXED REQUEST TERMS; OPTIONAL AMOUNT

Subject to the satisfaction of the conditions set forth in this Agreement, the parties agree (unless otherwise mutually agreed upon by the parties in writing) as follows:

Section 2.1 Fixed Request Notice. The Company may, from time to time in its sole discretion, no later than 9:30 a.m. (New York time) on the first Trading Day of the Pricing Period, provide to the Investor a Fixed Request notice, substantially in the form attached hereto as Exhibit A (the “Fixed Request Notice”), which Fixed Request Notice shall become effective at 9:30 a.m. (New York time) on the first Trading Day of the Pricing Period specified in the Fixed Request Notice; provided, however, that if the Company delivers the Fixed Request Notice to the Investor later than 9:30 a.m. (New York time) on a Trading Day, then the first Trading Day of such Pricing Period shall not be the Trading Day on which the Investor received such Fixed Request Notice, but rather shall be the next Trading Day (unless a subsequent Trading Day is therein specified). The Fixed Request Notice shall specify the Fixed Amount Requested, establish the Threshold Price for such Fixed Request, designate the first and last Trading Day of the Pricing Period and specify the Optional Amount, if any, that the Company elects to grant to the Investor during the Pricing Period and the applicable Threshold Price for such Optional Amount (the “Optional Amount Threshold Price”). The Threshold Price and the Optional Amount Threshold Price established by the Company in a Fixed Request Notice may be the same or different, in the Company’s sole discretion. Upon the terms and subject to the conditions of this Agreement, the Investor is obligated to accept each Fixed Request Notice prepared and delivered in accordance with the provisions of this Agreement.

Section 2.2 Fixed Requests. From time to time during the Investment Period, the Company may in its sole discretion deliver to the Investor a Fixed Request Notice for a specified Fixed Amount Requested, and the applicable discount price (the “Discount Price”) shall be determined, in accordance with the price and share amount parameters as set forth below or such other parameters mutually agreed upon by the Investor and the Company, and upon the terms and subject to the conditions of this Agreement, the Investor shall purchase from the Company the Shares subject to such Fixed Request Notice at the Discount Price; provided, however, that (i) if an ex-dividend date is established by the Trading Market in respect of the Common Stock on or between the first Trading Day of the applicable Pricing Period and the applicable Settlement Date, the Discount Price shall be reduced by the per share dividend amount and (ii) unless the parties otherwise mutually agree, the Company may not deliver any single Fixed Request Notice for a Fixed Amount Requested in excess of the lesser of (a) the amount in the applicable Fixed Amount Requested column below and (b) 2.5% of the Market Capitalization:


Threshold Price	Fixed Amount Requested	Discount Price
Equal to or greater than $35.00	Not to exceed $8,000,000	97.000% of the VWAP
Equal to or greater than $30.00 and less than $35.00	Not to exceed $7,000,000	96.750% of the VWAP
Equal to or greater than $25.00 and less than $30.00	Not to exceed $6,000,000	96.500% of the VWAP
Equal to or greater than $20.00 and less than $25.00	Not to exceed $5,000,000	96.250% of the VWAP


Equal to or greater than $15.00 and less than $20.00	Not to exceed $4,000,000	96.000% of the VWAP
Equal to or greater than $10.50 and less than $15.00	Not to exceed $3,000,000	95.800% of the VWAP
Equal to or greater than $9.50 and less than $10.50	Not to exceed $2,100,000	95.700% of the VWAP
Equal to or greater than $8.50 and less than $9.50	Not to exceed $1,900,000	95.600% of the VWAP
Equal to or greater than $7.50 and less than $8.50	Not to exceed $1,700,000	95.500% of the VWAP
Equal to or greater than $6.50 and less than $7.50	Not to exceed $1,500,000	95.250% of the VWAP
Equal to or greater than $5.50 and less than $6.50	Not to exceed $1,300,000	95.000% of the VWAP
Equal to or greater than $4.50 and less than $5.50	Not to exceed $1,100,000	94.500% of the VWAP
Equal to or greater than $3.00 and less than $4.50	Not to exceed $1,000,000	94.000% of the VWAP

Anything to the contrary in this Agreement notwithstanding, unless otherwise mutually agreed upon by the Investor and the Company, at no time shall the Investor be required to purchase more than $8,000,000 worth of Common Stock in respect of any Pricing Period (not including Common Stock subject to any Optional Amount). The date on which the Company delivers any Fixed Request Notice in accordance with this Section 2.2 hereinafter shall be referred to as a “Fixed Request Exercise Date”.

Section 2.3 Share Calculation. With respect to the Trading Days during the applicable Pricing Period for which the VWAP equals or exceeds the Threshold Price, the number of Shares to be issued by the Company to the Investor pursuant to a Fixed Request shall equal the aggregate sum of each quotient (calculated for each Trading Day during the applicable Pricing Period for which the VWAP equals or exceeds the Threshold Price) determined pursuant to the following equation (rounded to the nearest whole Share):


N =		(A x B)/C, where:

N =		the number of Shares to be issued by the Company to the Investor in respect of a Trading Day during the applicable Pricing Period for which the VWAP equals or exceeds the Threshold Price,

A =		0.10 (the “Multiplier”), provided, however, that if the Company and the Investor mutually agree prior to the commencement of a Pricing Period that the number of consecutive Trading Days constituting a Pricing Period shall be less than 10, then the Multiplier correspondingly shall be increased to equal the decimal equivalent (in 10-millionths) of a fraction, the numerator of which is one and the denominator of which equals the number of Trading Days in the reduced Pricing Period (it being hereby acknowledged and agreed that this proviso shall not apply to any unilateral determination by the Company to reduce a Pricing Period, but rather, Section 2.8 hereof shall apply),


B =		the total Fixed Amount Requested, and

C =		the applicable Discount Price.

Section 2.4 Limitation of Fixed Requests. The Company shall not make more than one Fixed Request in each Pricing Period. Not less than five Trading Days shall elapse between the end of one Pricing Period and the commencement of any other Pricing Period during the Investment Period. There shall be permitted a maximum of 24 Fixed Requests during the Investment Period. Each Fixed Request automatically shall expire immediately following the last Trading Day of each Pricing Period.

Section 2.5 Reduction of Commitment. On the Settlement Date with respect to a Pricing Period, the Investor’s Total Commitment under this Agreement automatically (and without the need for any amendment to this Agreement) shall be reduced, on a dollar-for-dollar basis, by the total amount of the Fixed Request Amount and the Optional Amount Dollar Amount, if any, for such Pricing Period paid to the Company at such Settlement Date.

Section 2.6 Below Threshold Price. If the VWAP on any Trading Day in a Pricing Period is lower than the Threshold Price, then for each such Trading Day the Fixed Amount Requested shall be reduced, on a dollar-for-dollar basis, by an amount equal to the product of (x) the Multiplier and (y) the total Fixed Amount Requested, and no Shares shall be purchased or sold with respect to such Trading Day, except as provided below. If trading in the Common Stock on NASDAQ (or any other U.S. national securities exchange on which the Common Stock is then listed) is suspended for any reason for more than three hours on any Trading Day, the Investor may at its option deem the price of the Common Stock to be lower than the Threshold Price for such Trading Day and, for each such Trading Day, the total amount of the Fixed Amount Requested shall be reduced as provided in the immediately preceding sentence, and no Shares shall be purchased or sold with respect to such Trading Day, except as provided below. For each Trading Day during a Pricing Period on which the VWAP is lower (or is deemed to be lower as provided in the immediately preceding sentence) than the Threshold Price, the Investor may in its sole discretion elect to purchase such U.S. dollar amount of Shares equal to the amount by which the Fixed Amount Requested has been reduced in accordance with this Section 2.6, at the Threshold Price multiplied by the applicable percentage determined in accordance with the price and share amount parameters set forth in Section 2.2. The Investor shall inform the Company via facsimile transmission not later than 8:00 p.m. (New York time) on the last Trading Day of such Pricing Period as to the number of Shares, if any, the Investor elects to purchase as provided in this Section 2.6.

Section 2.7 Settlement. The payment for, against simultaneous delivery of, Shares in respect of each Fixed Request shall be settled on the second Trading Day next following the last Trading Day of each Pricing Period, or on such earlier date as the parties may mutually agree (the “Settlement Date”). On each Settlement Date, the Company shall, or shall cause its transfer agent to, electronically transfer the Shares purchased by the Investor by crediting the Investor’s or its designees’ account at DTC through its Deposit/Withdrawal at Custodian (DWAC) system, which Shares shall be freely tradable and transferable and without restriction on resale, against simultaneous payment therefor to the Company’s designated account by wire transfer of immediately available funds; provided that if the Shares are received by the Investor later than 1:00 p.m. (New York time), payment therefor shall be made with next day funds. As set forth in Section 9.1(ii), a failure by the Company to deliver such Shares shall result in the payment of partial damages by the Company to the Investor.

Section 2.8 Reduction of Pricing Period. If during a Pricing Period the Company elects to reduce the number of Trading Days in such Pricing Period (and thereby amend its previously delivered Fixed Request Notice), the Company shall so notify the Investor before 9:00 a.m. (New York time) on any Trading Day during a Pricing Period (a “Reduction Notice”) and the last Trading Day of such Pricing Period shall be the Trading Day immediately preceding the Trading Day on which the Investor received such Reduction Notice; provided, however, that if the Company delivers the Reduction Notice later than 9:00 a.m. (New York time) on a Trading Day during a Pricing Period, then the last Trading Day of such Pricing Period instead shall be the Trading Day on which the Investor received such Reduction Notice.

Upon receipt of a Reduction Notice, the Investor (i) shall purchase the Shares in respect of each Trading Day in such reduced Pricing Period for which the VWAP equals or exceeds the Threshold Price in accordance with Section 2.3 hereof; (ii) may elect to purchase the Shares in respect of any Trading Day in such reduced Pricing Period for which the VWAP is (or is deemed to be) lower than the Threshold Price in accordance with Section 2.6 hereof; and (iii) may elect to exercise all or any portion of an Optional Amount on any Trading Day during such reduced Pricing Period in accordance with Sections 2.10 and 2.11 hereof.

In addition, upon receipt of a Reduction Notice, the Investor may elect to purchase such U.S. dollar amount of additional Shares equal to the product determined pursuant to the following equation:


D =		(A/B) × (B – C), where:

D =		the U.S. dollar amount of additional Shares to be purchased,

A =		the Fixed Amount Requested,

B =		10 or, for purposes of this Section 2.8, such lesser number of Trading Days as the parties may mutually agree to, and

C =		the number of Trading Days in the reduced Pricing Period,

at a per Share price equal to (x) the Fixed Amount Requested attributable to the reduced Pricing Period divided by (y) the number of Shares to be purchased during such reduced Pricing Period pursuant to clauses (i) and (ii) (as applicable) of the immediately preceding paragraph.

The Investor may also elect to exercise any portion of the applicable Optional Amount which was unexercised during the reduced Pricing Period by issuing an Optional Amount Notice to the Company not later than 10:00 a.m. (New York time) on the first Trading Day next following the last Trading Day of the reduced Pricing Period. The number of Shares to be issued upon exercise of such Optional Amount shall be calculated pursuant to the equation set forth in Section 2.10 hereof, except that “C” shall equal the greater of (i) the VWAP for the Common Stock on the last Trading Day of the reduced Pricing Period or (ii) the Optional Amount Threshold Price.

The payment for, against simultaneous delivery of, Shares to be purchased and sold in accordance with this Section 2.8 shall be settled on the second Trading Day next following the Trading Day on which the Investor receives a Reduction Notice.

Section 2.9 Optional Amount. With respect to any Pricing Period, the Company may in its sole discretion grant to the Investor the right to exercise, from time to time during the Pricing Period (but not more than once on any Trading Day), all or any portion of an Optional Amount. The maximum Optional Amount Dollar Amount and the Optional Amount Threshold Price shall be set forth in the Fixed Request Notice. If an ex-dividend date is established by the Trading Market in respect of the Common Stock on or between the first Trading Day of the applicable Pricing Period and the applicable Settlement Date, the applicable exercise price in respect of the Optional Amount shall be reduced by the per share dividend amount. Each daily Optional Amount exercise shall be aggregated during the Pricing Period and settled on the next Settlement Date. The Optional Amount Threshold Price designated by the Company in its Fixed Request Notice shall apply to each Optional Amount exercised during the applicable Pricing Period.

Section 2.10 Calculation of Optional Amount Shares. The number of shares of Common Stock to be issued in connection with the exercise of an Optional Amount shall be the quotient determined pursuant to the following equation (rounded to the nearest whole Share):


O =		A/(B × C), where:

O =		the number of shares of Common Stock to be issued in connection with such Optional Amount exercise,

A =		the Optional Amount Dollar Amount with respect to which the Investor has delivered an Optional Amount Notice,

B =		the applicable percentage determined in accordance with the price and shares amount parameters set forth in Section 2.2 (with the Optional Amount Threshold Price serving as the Threshold Price for such purposes), and

C =		the greater of (i) the VWAP for the Common Stock on the day the Investor delivers the Optional Amount Notice and (ii) the Optional Amount Threshold Price.

Section 2.11 Exercise of Optional Amount. If granted by the Company to the Investor with respect to a Pricing Period, all or any portion of the Optional Amount may be exercised by the Investor on any Trading Day during the Pricing Period, subject to the limitations set forth in Section 2.9. As a condition to each exercise of an Optional Amount pursuant to this Section 2.11, the Investor shall issue an Optional Amount Notice to the Company no later than 8:00 p.m. (New York time) on the day of such Optional Amount exercise. If the Investor does not exercise an Optional Amount in full by 8:00 p.m. (New York time) on the last Trading Day of the applicable Pricing Period, such unexercised portion of the Investor’s Optional Amount with respect to that Pricing Period automatically shall lapse and terminate.

Section 2.12 Aggregate Limit. Notwithstanding anything to the contrary contained in this Agreement, in no event may the Company issue a Fixed Request Notice or grant an Optional Amount to the extent that the sale of Shares pursuant thereto and pursuant to all prior Fixed Request Notices and Optional Amounts issued hereunder, and as partial damages pursuant to Section 9.1(ii), would cause the Company to sell or the Investor to purchase Shares which in the aggregate are in excess of the Aggregate Limit. If the Company issues a Fixed Request Notice or Optional Amount that otherwise would permit the Investor to purchase shares of Common Stock which would cause the aggregate purchases by Investor hereunder to exceed the Aggregate Limit, such Fixed Request Notice or Optional Amount shall be void ab initio to the extent of the amount by which the dollar value of shares or number of shares, as the case may be, of Common Stock otherwise issuable pursuant to such Fixed Request Notice or Optional Amount together with the dollar value of shares or number of shares, as the case may be, of all other Common Stock purchased by the Investor pursuant hereto, or issued as partial damages pursuant to Section 9.1(ii), would exceed the Aggregate Limit. The Company hereby represents, warrants and covenants that neither it nor any of its Subsidiaries (i) has effected any transaction or series of transactions, (ii) is a party to any pending transaction or series of transactions or (iii) shall enter into any contract, agreement, agreement-in-principle, arrangement or understanding with respect to, or shall effect, any Other Financing which, in any of such cases, may be aggregated with the transactions contemplated by this Agreement for purposes of determining whether approval of the Company’s shareholders is required under any bylaw, listed securities maintenance standards or other rules of the Trading Market; provided, however, that the Company shall be permitted to take any action referred to in clause (iii) above if (a) the Company has timely provided the Investor with an Integration Notice as provided in Section 5.6(ii) hereof and (b) unless the Investor has previously terminated this Agreement pursuant to Section 7.2, the Company obtains any requisite shareholder approval which may be required for the Company to consummate such Other Financing described in such Integration Notice.

At the Company’s sole discretion, and effective automatically upon delivery of notice thereof by the Company to the Investor, this Agreement may be amended by the Company from time to time to reduce the Aggregate Limit by a specified dollar amount and/or number of shares of Common Stock as shall be determined by the Company in its sole discretion; provided, however, that any such amendment of this Agreement (and any such purported amendment) shall be void and of no force and effect if the effect thereof would restrict, materially delay, conflict with or impair the ability or right of the Company to perform its obligations under this Agreement, including, without limitation, the obligation of the Company to deliver Shares to the Investor in respect of a previously provided Fixed Request Notice or Optional Amount on the applicable Settlement Date. In the event the Company shall have elected to reduce the Aggregate Limit as provided in the immediately preceding sentence, at the Company’s sole discretion, and effective automatically upon delivery of notice thereof by the Company to the Investor, the Company may subsequently amend this Agreement to increase the Aggregate Limit up to $40,000,000; provided, however, that in no event shall the Company be entitled to issue Fixed Requests and grant Optional Amounts during the remainder of the Investment Period for an aggregate amount greater than the amount obtained by subtracting (x) the aggregate of all Fixed Request Amounts and Optional Amount Dollar Amounts (including any amounts paid as partial damages pursuant to Section 9.1(ii) hereunder) covered by all Fixed Requests and Optional Amounts theretofore issued or granted by the Company in respect of which a settlement has occurred pursuant to Section 2.7 from (y) $40,000,000, subject in all cases to the Trading Market Limit (except as expressly provided in Section 2.13).

Section 2.13 Trading Market Regulation. Notwithstanding anything in this Agreement to the contrary, the Trading Market Limit shall not be applicable for any purposes of this Agreement or the transactions contemplated hereby, solely to the extent (and only for so long as) the Average Discount Price shall equal or exceed the Base Price (it being hereby acknowledged and agreed that the Trading Market Limit shall be applicable for all purposes of this Agreement and the transactions contemplated hereby at all other times during the term of this Agreement); provided, however, that the Company shall not issue any shares of Common Stock under this Agreement if such issuance would otherwise breach the Company’s obligations under the rules and regulations of the Trading Market. “Base Price” shall mean a price per Share equal to $5.02, representing the consolidated closing bid price of the Common Stock as reported on the Trading Market on the Trading Day immediately preceding the Effective Date, subject to (a) upward adjustment (by such amount to be mutually agreed by the Company and the Investor consistent with the rules and regulations of the Trading Market) in the event any shares of Common Stock are issued by the Company as partial damages pursuant to Section 9.1(ii) and (b) adjustment for any stock splits, stock combinations, stock dividends, recapitalizations and other similar transactions that occur on or after the date of this Agreement. The Company hereby represents and warrants to the Investor that the book value per share of Common Stock on the Trading Day immediately preceding the Effective Date is less than the Base Price. “Average Discount Price” shall mean a price per Share (rounded to the nearest tenth of a cent) equal to the quotient obtained by dividing (i) the total aggregate gross purchase price paid by the Investor for all Shares purchased pursuant to all Fixed Requests and Optional Amounts under this Agreement, by (ii) the total aggregate number of Shares issued pursuant to all Fixed Requests and Optional Amounts under this Agreement. The provisions of this Section 2.13 shall be implemented in a manner otherwise than in strict conformity with the terms of this Section 2.13, only if necessary to ensure compliance with the rules and regulations of the Trading Market.

The Commission has not notified the Company of any objection to the use of the form of the Registration Statement pursuant to Rule 401(g)(1) under the Securities Act. The Registration Statement complied in all material respects on the date on which it was declared effective by the Commission, and will comply in all material respects at each deemed effective date with respect to the Investor pursuant to Rule 430B(f)(2) of the Securities Act, with the requirements of the Securities Act, and the Registration Statement (including the documents incorporated by reference therein) did not on the date it was declared effective by the Commission, and shall not at each deemed effective date with respect to the Investor pursuant to Rule 430B(f)(2) of the Securities Act, 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; provided that this representation and warranty does not apply to statements in or omissions from the Registration Statement made in reliance upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the Investor expressly for use therein. The Registration Statement, as of the Effective Date, meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act. The Base Prospectus complied in all material respects on its date and on the Effective Date, and will comply in all material respects on each applicable Fixed Request Exercise Date and, when taken together with the applicable Prospectus Supplement and any applicable Permitted Free Writing Prospectus, on each applicable Settlement Date, with the requirements of the Securities Act and did not on its date and on the Effective Date and shall not on each applicable Fixed Request Exercise Date and, when taken together with the applicable Prospectus Supplement and any applicable Permitted Free Writing Prospectus, on each applicable Settlement Date 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 light of the circumstances under which they were made, not misleading; provided that this representation and warranty does not apply to statements in or omissions from the Base Prospectus, each applicable Prospectus Supplement and any Permitted Free Writing Prospectus made in reliance upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the Investor expressly for use therein.

(iii) Each Prospectus Supplement required to be filed pursuant to Sections 1.4 and 5.9 hereof, when taken together with the Base Prospectus and any applicable Permitted Free Writing Prospectus, on its date and on the applicable Settlement Date, shall comply in all material respects with the provisions of the Securities Act and shall not on its date and on the applicable Settlement Date 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 light of the circumstances under which they are made, not misleading, except that this representation and warranty does not apply to statements in or omissions from any Prospectus Supplement made in reliance upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the Investor expressly for use therein.

(iv) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Securities Act) relating to the Shares, the Company was not and is not an

“ineligible issuer” (as defined in Rule 405 under the Securities Act). Each Permitted Free Writing Prospectus (a) shall conform in all material respects to the requirements of the Securities Act on the date of its first use, (b) when considered together with the Prospectus on each applicable Fixed Request Exercise Date and on each applicable Settlement Date, shall 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, in the light of the circumstances under which they are made, not misleading, and (c) shall not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated by reference therein and any Prospectus Supplement deemed to be a part thereof that has not been superseded or modified. The immediately preceding sentence does not apply to statements in or omissions from any Permitted Free Writing Prospectus made in reliance upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the Investor expressly for use therein.

(v) Prior to the Effective Date, the Company has not distributed any offering material in connection with the offering and sale of the Shares. From and after the Effective Date and prior to the completion of the distribution of the Shares, the Company shall not distribute any offering material in connection with the offering and sale of the Shares, other than the Registration Statement, the Base Prospectus as supplemented by any Prospectus Supplement or a Permitted Free Writing Prospectus.

Section 4.19 Employees. As of the Effective Date, neither the Company nor any Subsidiary of the Company has any collective bargaining arrangements or agreements covering any of its employees, except as set forth in the Commission Documents. As of the Effective Date, except as disclosed in the Registration Statement or the Commission Documents, no officer, consultant or key employee of the Company or any Subsidiary whose termination, either individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect, has terminated or, to the knowledge of the Company, has any present intention of terminating his or her employment or engagement with the Company or any Subsidiary.

Section 4.20 Use of Proceeds. The proceeds from the sale of the Shares shall be used by the Company and its Subsidiaries as set forth in the Base Prospectus and any Prospectus Supplement filed pursuant to Sections 1.4 and 5.9.

Section 4.21 Investment Company Act Status. The Company is not, and as a result of the consummation of the transactions contemplated by this Agreement and the application of the proceeds from the sale of the Shares as set forth in the Base Prospectus and any Prospectus Supplement shall not be required to be registered as an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

Section 4.22 ERISA. No liability to the Pension Benefit Guaranty Corporation has been incurred with respect to any Plan by the Company or any of its Subsidiaries which has had or would have a Material Adverse Effect. No “prohibited transaction” (as defined in Section 406 of ERISA or Section 4975 of the Code) or “accumulated funding deficiency” (as defined in Section 203 of ERISA) or any of the events set forth in Section 4043(b) of ERISA has occurred with respect to any Plan which has had or would have a Material Adverse Effect, and the

execution and delivery of this Agreement and the issuance and sale of the Shares hereunder shall not result in any of the foregoing events. Each Plan is in compliance in all material respects with applicable law, including ERISA and the Code; the Company has not incurred and does not expect to incur liability under Title IV of ERISA with respect to the termination of, or withdrawal from, any Plan; and each Plan for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualifications. As used in this Section 4.22, the term “Plan” shall mean an “employee pension benefit plan” (as defined in Section 3 of ERISA) which is or has been established or maintained, or to which contributions are or have been made, by the Company or any Subsidiary or by any trade or business, whether or not incorporated, which, together with the Company or any Subsidiary, is under common control, as described in Section 414(b) or (c) of the Code.

Section 4.23 Taxes. The Company (i) has filed all necessary federal, state and foreign income and franchise tax returns or has duly requested extensions thereof, except for those the failure of which to file would not have a Material Adverse Effect, (ii) has paid all federal, state, local and foreign taxes due and payable for which it is liable, except to the extent that any such taxes are being contested in good faith and by appropriate proceedings, except for such taxes the failure of which to pay would not have a Material Adverse Effect, and (iii) does not have any tax deficiency or claims outstanding or assessed or, to the Company’s knowledge, proposed against it which would have a Material Adverse Effect.

Section 4.24 Insurance. The Company carries, or is covered by, insurance in such amounts and covering such risks as the Company deems is adequate for the conduct of its and its Subsidiaries’ businesses and the value of their respective properties and as is customary for companies engaged in similar businesses in similar industries.

Section 4.25 Acknowledgement Regarding Investor’s Purchase of Shares. The Company acknowledges and agrees that the Investor is acting solely in the capacity of an arm’s length purchaser with respect to this Agreement and the transactions contemplated hereunder. The Company further acknowledges that the Investor is not acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereunder, and any advice given by the Investor or any of its representatives or agents in connection with this Agreement and the transactions contemplated hereunder is merely incidental to the Investor’s purchase of the Shares.

ARTICLE V

The Company covenants with the Investor, and the Investor covenants with the Company, as follows, which covenants of one party are for the benefit of the other party, during the Investment Period:

Section 5.1 Securities Compliance; FINRA Filing.

(i) The Company shall notify the Trading Market in accordance with its applicable rules and regulations of the transactions contemplated by this Agreement, and shall take all necessary action, undertake all proceedings and obtain all registrations, permits, consents and approvals for the legal and valid issuance of the Shares to the Investor in accordance with the terms of this Agreement.

(ii) The Company shall (with the Investor’s assistance) assist Reedland with the preparation and filing with the FINRA’s Corporate Financing Department via CobraDesk (not later than 24 hours after the Effective Date) of all documents and information required to be filed with the FINRA pursuant to FINRA Rule 5110 with regard to the transactions contemplated by this Agreement (the “FINRA Filing”). Prior to the Effective Date, the Company shall have paid to the FINRA by wire transfer of immediately available funds the applicable filing fee with respect to the FINRA Filing, and the Company shall be solely responsible for payment of such fee. The parties hereby agree to provide each other and Reedland all requisite information and otherwise to assist each other and Reedland in a timely fashion in order for Reedland to complete the preparation and submission of the FINRA Filing in accordance with this Section 5.1(ii) and to assist Reedland in promptly responding to any inquiries or requests from FINRA or its staff. Each party hereto shall (A) promptly notify the other party and Reedland of any communication to that party or its affiliates from the FINRA, including, without limitation, any request from the FINRA or its staff for amendments or supplements to or additional information in respect of the FINRA Filing and permit the other party and Reedland to review in advance any proposed written communication to the FINRA and (B) furnish the other party and Reedland with copies of all written correspondence, filings and communications between them and their affiliates and their respective representatives and advisors, on the one hand, and the FINRA or members of its staff, on the other hand, with respect to this Agreement or the transactions contemplated hereby. Each of the parties hereto agrees to use its commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other party and Reedland in doing, all things necessary, proper or advisable to obtain as promptly as practicable (but in no event later than 60 days after the Effective Date) written confirmation from the FINRA to the effect that the FINRA’s Corporate Financing Department has determined not to raise any objection with respect to the fairness and reasonableness of the terms of this Agreement or the transactions contemplated hereby; provided, however, that the Investor shall have no responsibility for the compliance or non-compliance of any Broker-Dealer with FINRA Rule 5110 and shall not be required to (x) disclose to the FINRA or to any other governmental agency, person or entity any business, financial or other information that the Investor deems, in its sole and absolute discretion, to be proprietary, confidential or otherwise sensitive information, (y) amend, modify or change any of the terms or conditions of this Agreement or (z) otherwise take any other action, including, without limitation, modifying the Discount Price thresholds referred to in Section 2.2 or the amount of fees and commissions to be paid to the Broker-Dealer in connection with the transactions contemplated by this Agreement, in each case, in such a manner that would, in the Investor’s sole and absolute discretion, render the terms and conditions of this Agreement and the transactions contemplated hereby to be no longer advisable to the Investor. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be permitted to deliver any Fixed Request Notice to the Investor, and the Investor shall not be obligated to purchase any Shares pursuant to a Fixed Request Notice, unless and until the

parties hereto and Reedland shall have received written confirmation from the FINRA to the effect that the FINRA’s Corporate Financing Department has determined not to raise any objection with respect to the fairness and reasonableness of the terms of this Agreement or the transactions contemplated hereby.

Section 5.2 Registration and Listing. The Company shall take all action necessary to cause the Common Stock to continue to be registered as a class of securities under Sections 12(b) or 12(g) of the Exchange Act, shall comply with its reporting and filing obligations under the Exchange Act, and shall not take any action or file any document (whether or not permitted by the Securities Act) to terminate or suspend such registration or to terminate or suspend its reporting and filing obligations under the Exchange Act or Securities Act, except as permitted herein. The Company shall use its reasonable best efforts to continue the listing and trading of its Common Stock and the listing of the Shares purchased by Investor hereunder on the Trading Market (including, without limitation, maintaining sufficient tangible net assets), and shall comply with the Company’s reporting, filing and other obligations under the bylaws, listed securities maintenance standards and other rules and regulations of the FINRA and the Trading Market. The Company shall not take any action which could be reasonably expected to result in the delisting or suspension (other than any suspension of trading of limited duration agreed to by the Company, which suspension shall be terminated prior to any Fixed Request Exercise Date or Settlement Date) of the Common Stock on the Trading Market.

Section 5.3 Compliance with Laws.

(i) The Company shall comply, and cause each Subsidiary to comply, (a) with all laws, rules, regulations and orders applicable to the business and operations of the Company and its Subsidiaries except as would not have a Material Adverse Effect and (b) with all applicable provisions of the Securities Act, the Exchange Act, the rules and regulations of the FINRA and the listing standards of the Trading Market. Without limiting the generality of the foregoing, neither the Company nor any of its officers, directors or affiliates has taken or will take, directly or indirectly, any action designed or intended to stabilize or manipulate the price of any security of the Company, or which caused or resulted in, or which would in the future reasonably be expected to cause or result in, stabilization or manipulation of the price of any security of the Company.

(ii) The Investor shall comply with all laws, rules, regulations and orders applicable to the performance by it of its obligations under this Agreement and its investment in the Shares, except as would not, individually or in the aggregate, prohibit or otherwise interfere with the ability of the Investor to enter into and perform its obligations under this Agreement in any material respect. Without limiting the foregoing, the Investor shall comply with all applicable provisions of the Securities Act and the Exchange Act.

Section 5.4 Keeping of Records and Books of Account; Foreign Corrupt Practices Act.

(i) The Company shall keep and cause each Subsidiary to keep adequate records and books of account, in which complete entries shall be made in accordance with GAAP consistently applied, reflecting all financial transactions of the Company and its

Subsidiaries, and in which, for each fiscal year, all proper reserves for depreciation, depletion, obsolescence, amortization, taxes, bad debts and other purposes in connection with its business shall be made. The Company shall maintain a system of internal accounting controls that (a) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (b) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (c) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s financial statements (it being acknowledged and agreed that the identification by the Company and/or its independent registered public accounting firm of any “significant deficiencies” or “material weaknesses” (each as defined by the Public Company Accounting Oversight Board) in the Company’s internal controls over its financial reporting shall not, in and of itself, constitute a breach of this Section 5.4(i)).

(ii) Neither the Company, nor any of its Subsidiaries, nor to the knowledge of the Company, any of their respective directors, officers, agents, employees or any other persons acting on their behalf shall, in connection with the operation of the Company’s and its Subsidiaries’ respective businesses, (a) use any corporate funds for unlawful contributions, payments, gifts or entertainment or to make any unlawful expenditures relating to political activity to government officials, candidates or members of political parties or organizations, (b) pay, accept or receive any unlawful contributions, payments, expenditures or gifts, or (c) violate or operate in noncompliance with any export restrictions, anti-boycott regulations, embargo regulations or other applicable domestic or foreign laws and regulations, except for such violations or noncompliant operations that would not likely result in a Material Adverse Effect.

(iii) Subject to the requirements of Section 5.12 of this Agreement, from time to time from and after the period beginning with the third Trading Day immediately preceding each Fixed Request Exercise Date through and including the applicable Settlement Date, the Company shall make available for inspection and review by the Investor during normal business hours and after reasonable notice, customary documentation reasonably requested by the Investor and/or its appointed counsel or advisors to conduct due diligence.

Section 5.5 Limitations on Holdings and Issuances. Notwithstanding any other provision of this Agreement, the Company shall not issue and the Investor shall not purchase any shares of Common Stock which, when aggregated with all other shares of Common Stock then beneficially owned (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder) by the Investor and its affiliates, would result in the beneficial ownership by the Investor of more than 9.9% of the then issued and outstanding shares of Common Stock. Promptly following any request by the Company, the Investor shall inform the Company of the number of shares of Common Stock then beneficially owned by the Investor and its affiliates.

Section 5.6 Other Agreements and Other Financings.

(i) The Company shall not enter into, announce or recommend to its shareholders any agreement, plan, arrangement or transaction in or of which the terms thereof would restrict, materially delay, conflict with or impair the ability or right of the Company to perform its obligations under this Agreement, including, without limitation, the obligation of the Company to deliver Shares to the Investor in respect of a previously provided Fixed Request Notice or Optional Amount on the applicable Settlement Date. For the avoidance of doubt, nothing in this Section 5.6(i) shall in any way limit the Company’s right to terminate this Agreement in accordance with Section 7.1 (subject in all cases to Section 7.3).

(ii) If the Company enters into any agreement, plan, arrangement or transaction with a third party or seeks to utilize any existing agreement, plan or arrangement with a third party, in each case the principal purpose of which is to implement, effect or consummate, at any time during the period beginning on the first Trading Day of any Pricing Period and ending on the second Trading Day next following the applicable Settlement Date (the “Reference Period”), an Other Financing that does not constitute an Acceptable Financing, the Company shall provide prompt notice thereof (an “Other Financing Notice”) to the Investor; provided, however, that such Other Financing Notice must be received by the Investor not later than the earlier of (a) 48 hours after the Company’s execution of any agreement, plan, arrangement or transaction relating to such Other Financing (or, with respect to any existing agreement, plan or arrangement, 48 hours after the Company has determined to utilize any such existing agreement, plan or arrangement to implement, effect or consummate such Other Financing) and (b) the second Trading Day immediately preceding the applicable Settlement Date with respect to the applicable Fixed Request Notice; provided, further, that the Company shall notify the Investor within 24 hours (an “Integration Notice”) if it enters into any agreement, plan, arrangement or transaction with a third party, the principal purpose of which is to obtain at any time during the Investment Period an Other Financing that may be aggregated with the transactions contemplated by this Agreement for purposes of determining whether approval of the Company’s shareholders is required under any bylaw, listed securities maintenance standards or other rules of the Trading Market and, if required under applicable law, including, without limitation, Regulation FD promulgated by the Commission, or under the applicable rules and regulations of the Trading Market, the Company shall publicly disclose such information in accordance with Regulation FD and the applicable rules and regulations of the Trading Market. For purposes of this Section 5.6(ii), any press release issued by, or Commission Document filed by, the Company shall constitute sufficient notice, provided that it is issued or filed, as the case may be, within the time requirements set forth in the first sentence of this Section 5.6(ii) for an Other Financing Notice or an Integration Notice, as applicable. With respect to any Pricing Period for which the Company is required to provide an Other Financing Notice pursuant to the first sentence (including the provisos thereto) of this Section 5.6(ii), the Investor shall (i) have the option to purchase the Shares subject to the Fixed Request at (x) the price therefor in accordance with the terms of this Agreement or (y) the third party’s per share purchase price in connection with the Other Financing, net of such third party’s discounts, Warrant Value and fees, or (ii) the Investor may elect to not purchase any Shares subject to the Fixed Request for that Pricing Period. An “Other Financing” shall mean (w) the issuance of Common Stock for a purchase price less than, or the issuance of securities convertible into or exchangeable for Common Stock at an exercise or conversion price (as the case may be) less than, the then Current Market Price of the Common

Stock (including, without limitation, pursuant to any “equity line” or other financing that is substantially similar to the financing provided for under this Agreement, or pursuant to any other transaction in which the purchase, conversion or exchange price for such Common Stock is determined using a floating discount or other post-issuance adjustable discount to the then Current Market Price (any such transaction, a “Similar Financing”)), in each case, after all fees, discounts, Warrant Value and commissions associated with the transaction (a “Below Market Offering”); (x) an “at-the-market” offering of Common Stock or securities convertible into or exchangeable for Common Stock pursuant to Rule 415(a)(4) under the Securities Act (an “ATM”); (y) the implementation by the Company of any mechanism in respect of any securities convertible into or exchangeable for Common Stock for the reset of the purchase price of the Common Stock to below the then Current Market Price of the Common Stock (including, without limitation, any antidilution or similar adjustment provisions in respect of any Company securities, but specifically excluding customary adjustments for stock splits, stock dividends, stock combinations and similar events) (a “Price Reset Provision”); or (z) the issuance of options, warrants or similar rights of subscription in each case not constituting an Acceptable Financing. “Acceptable Financing” shall mean the issuance by the Company of: (1) debt securities or any class or series of preferred stock of the Company, in each case that are not convertible into or exchangeable for Common Stock or securities convertible into or exchangeable for Common Stock; (2) shares of Common Stock or securities convertible into or exchangeable for Common Stock (including, without limitation, convertible debt securities) other than in connection with a Below Market Offering or an ATM, and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof; (3) shares of Common Stock or securities convertible into or exchangeable for Common Stock (including, without limitation, convertible debt securities) in connection with an underwritten public offering of securities of the Company or a registered direct public offering of securities of the Company, in each case where the price per share of such Common Stock (or the conversion or exercise price of such securities, as applicable) is fixed concurrently with the execution of definitive documentation relating to such offering, and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof; (4) shares of Common Stock or securities convertible into or exchangeable for Common Stock in connection with awards under the Company’s benefit and equity plans and arrangements or shareholder rights plan (as applicable) and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof; (5) shares of Common Stock issuable upon the conversion, exercise or exchange of equity awards or convertible, exercisable or exchangeable securities (including, without limitation, convertible debt securities) outstanding as of the Effective Date; (6) shares of Common Stock in connection with stock splits, stock dividends, stock combinations, recapitalizations, reclassifications and similar events; (7) shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock (including, without limitation, convertible debt securities) issued in connection with the acquisition, license or sale of one or more other companies, equipment, technologies, other assets or lines of business, and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof; (8) shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock (including, without limitation, convertible debt securities) or similar rights to subscribe for the purchase of shares of Common Stock in connection with technology sharing, collaboration, partnering, licensing, research and joint development agreements (or amendments thereto) with third parties, and the issuance of shares of Common Stock upon the conversion, exercise or exchange thereof (including, for the avoidance of doubt,

Section 5.7 Stop Orders. The Company shall advise the Investor promptly (but in no event later than 24 hours) and shall confirm such advice in writing: (i) of the Company’s receipt of notice of any request by the Commission for amendment of or a supplement to the Registration Statement, the Prospectus, any Permitted Free Writing Prospectus or for any additional information; (ii) of the Company’s receipt of notice of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or prohibiting or suspending the use of the Prospectus or any Prospectus Supplement, or of the suspension of qualification of the Shares for offering or sale in any jurisdiction, or the initiation or contemplated initiation of any proceeding for such purpose; and (iii) of the Company becoming aware of the happening of any event, which makes any statement of a material fact made in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus untrue or which requires the making of any additions to or changes to the statements then made in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus in order to state a material fact required by the Securities Act to be stated therein or necessary in order to make the statements then made therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading, or of the necessity to amend the Registration Statement or supplement the Prospectus or any Permitted Free Writing Prospectus to comply with the Securities Act or any other law. The Company shall not be required to disclose to the Investor the substance or specific reasons of any of the events set forth in clauses (i) through (iii) of the immediately preceding sentence, but rather, shall only be required to disclose that the event has occurred. The Company shall not issue any Fixed Request during the continuation of any of the foregoing events. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement or prohibiting or suspending the use of the Prospectus or any Prospectus Supplement, the Company shall use commercially reasonable efforts to obtain the withdrawal of such order at the earliest possible time. The Company shall also advise the Investor promptly (but in no event later than 24 hours) and shall confirm such advice in writing of the Company becoming aware of the happening of any event, which makes any statement made in the FINRA Filing untrue or which requires the making of any additions to or changes to the statements then made in the FINRA Filing in order to comply with FINRA Rule 5110.

Section 5.8 Amendments to the Registration Statement; Prospectus Supplements; Free Writing Prospectuses.

(i) Except as provided in this Agreement and other than periodic and current reports required to be filed pursuant to the Exchange Act, the Company shall not file with the Commission any amendment to the Registration Statement that relates to the Investor, the Agreement or the transactions contemplated hereby or file with the Commission any Prospectus Supplement that relates to the Investor, this Agreement or the transactions contemplated hereby

with respect to which (a) the Investor shall not previously have been advised, (b) the Company shall not have given due consideration to any comments thereon received from the Investor or its counsel, or (c) the Investor shall reasonably object after being so advised, unless the Company reasonably has determined that it is necessary to amend the Registration Statement or make any supplement to the Prospectus to comply with the Securities Act or any other applicable law or regulation, in which case the Company shall promptly (but in no event later than 24 hours) so inform the Investor, the Investor shall be provided with a reasonable opportunity to review and comment upon any disclosure relating to the Investor and the Company shall expeditiously furnish to the Investor an electronic copy thereof. In addition, for so long as, in the reasonable opinion of counsel for the Investor, the Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required to be delivered in connection with any purchase or sale of Shares by the Investor, the Company shall not file any Prospectus Supplement with respect to the Shares without delivering or making available a copy of such Prospectus Supplement, together with the Base Prospectus, to the Investor promptly.

(ii) The Company has not made, and agrees that unless it obtains the prior written consent of the Investor it will not make, an offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed by the Company or the Investor with the Commission or retained by the Company or the Investor under Rule 433 under the Securities Act. The Investor has not made, and agrees that unless it obtains the prior written consent of the Company it will not make an offer relating to the Shares that would constitute a Free Writing Prospectus required to be filed by the Company with the Commission or retained by the Company under Rule 433 under the Securities Act. Any such Issuer Free Writing Prospectus or other Free Writing Prospectus consented to by the Investor or the Company is referred to in this Agreement as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

The Company consents to the use of the Prospectus (and of any Prospectus Supplement thereto) in accordance with the provisions of the Securities Act and with the securities or “blue sky” laws of the jurisdictions in which the Shares may be sold by the Investor, in connection with the offering and sale of the Shares and for such period of time thereafter as the Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is required by the Securities Act to be delivered in connection with sales of the Shares. If during such period of time any event shall occur that in the judgment of the Company and its counsel is required to be set forth in the Registration Statement or the Prospectus or any Permitted Free Writing

Prospectus or should be set forth therein in order to make the statements made therein (in the case of the Prospectus or Permitted Free Writing Prospectus, in light of the circumstances under which they were made) not misleading, or if it is necessary to amend the Registration Statement or supplement or amend the Prospectus or any Permitted Free Writing Prospectus to comply with the Securities Act or any other applicable law or regulation, the Company shall forthwith prepare and, subject to Section 5.8 above, file with the Commission an appropriate amendment to the Registration Statement or Prospectus Supplement to the Prospectus (or supplement to the Permitted Free Writing Prospectus) and shall expeditiously furnish or make available to the Investor an electronic copy thereof.

Section 5.10 Selling Restrictions.

Prior to and during the Restricted Period, the Investor shall not grant any option to purchase or acquire any right to dispose or otherwise dispose for value of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for, or warrants to purchase, any shares of Common Stock, or enter into any swap, hedge or other agreement that transfers, in whole or in part, the economic risk of ownership of the Common Stock, except for such sales expressly permitted by this Section 5.10(i).

(ii) In addition to the foregoing, in connection with any sale of the Company’s securities (including any sale permitted by paragraph (i) above), the Investor shall comply in all respects with all applicable laws, rules, regulations and orders, including, without limitation, the requirements of the Securities Act and the Exchange Act.

ARTICLE VIII

INDEMNIFICATION

Section 8.1 General Indemnity.

(i) Indemnification by the Company. The Company shall indemnify and hold harmless the Investor, each affiliate, employee, representative and advisor of and to the Investor, and each person, if any, who controls the Investor within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act from and against all losses, claims, damages, liabilities and expenses (including reasonable costs of defense and investigation and all attorneys’ fees) to which the Investor and each such other person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities and expenses (or actions in respect thereof) arise out of or are based upon (a) any violation of United States federal or state securities laws or the rules and regulations of the Trading Market in connection with the transactions contemplated by this Agreement by the Company or any of its Subsidiaries, affiliates, officers, directors or employees, (b) any untrue statement or alleged untrue statement of a material fact contained, or incorporated by reference, in the Registration Statement or any amendment thereto or any omission or alleged omission to state therein, or in any document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein not misleading, or (c) any untrue statement or alleged untrue statement of a material fact contained, or incorporated by reference, in the Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or in any “issuer information” (as defined in Rule 433 under the Securities Act) of the Company, which “issuer information” is required to be, or is, filed with the Commission or otherwise contained in any Free Writing Prospectus, or any amendment or supplement thereto, or any omission or alleged omission to state therein, or in any document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that (A) the Company shall not be liable under this Section 8.1(i) to the extent that a court of competent jurisdiction shall have determined by a final judgment (from which no further appeals are available) that such loss, claim, damage, liability or expense resulted directly and solely from any such acts or failures to act, undertaken or omitted to be taken by the Investor or such person through its gross negligence, bad faith or willful or reckless misconduct, (B) the foregoing indemnity shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Investor expressly for use in the Current Report,

any Prospectus Supplement or any Permitted Free Writing Prospectus, or any amendment thereof or supplement thereto, and (C) with respect to the Prospectus, the foregoing indemnity shall not inure to the benefit of the Investor or any such person from whom the person asserting any loss, claim, damage, liability or expense purchased Common Stock, if copies of all Prospectus Supplements required to be filed pursuant to Section 1.4 and 5.9, together with the Base Prospectus, were timely delivered or made available to the Investor pursuant hereto and a copy of the Base Prospectus, together with a Prospectus Supplement (as applicable), was not sent or given by or on behalf of the Investor or any such person to such person, if required by law to have been delivered, at or prior to the written confirmation of the sale of the Common Stock to such person, and if delivery of the Base Prospectus, together with a Prospectus Supplement (as applicable), would have cured the defect giving rise to such loss, claim, damage, liability or expense.

Subject to Section 8.2, the Company shall reimburse the Investor and each such controlling person promptly upon demand (with accompanying presentation of documentary evidence) for all legal and other costs and expenses reasonably incurred by the Investor or such indemnified persons in investigating, defending against, or preparing to defend against any such claim, action, suit or proceeding with respect to which it is entitled to indemnification.

(ii) Indemnification by the Investor. The Investor shall indemnify and hold harmless the Company, each of its directors and officers, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act from and against all losses, claims, damages, liabilities and expenses (including reasonable costs of defense and investigation and all attorneys fees) to which the Company and each such other person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities and expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Current Report or any Prospectus Supplement or Permitted Free Writing Prospectus, or in any amendment thereof or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case, to the extent, but only to the extent, the untrue statement, alleged untrue statement, omission or alleged omission was made in reliance upon, and in conformity with, written information furnished by the Investor to the Company expressly for inclusion in the Current Report or such Prospectus Supplement or Permitted Free Writing Prospectus, or any amendment thereof or supplement thereto.

Subject to Section 8.2, the Investor shall reimburse the Company and each such director, officer or controlling person promptly upon demand for all legal and other costs and expenses reasonably incurred by the Company or such indemnified persons in investigating, defending against, or preparing to defend against any such claim, action, suit or proceeding with respect to which it is entitled to indemnification.

Section 8.2 Indemnification Procedures. Promptly after a person receives notice of a claim or the commencement of an action for which the person intends to seek indemnification under Section 8.1, the person will notify the indemnifying party in writing of the claim or commencement of the action, suit or proceeding; provided, however, that failure to notify the

indemnifying party will not relieve the indemnifying party from liability under Section 8.1, except to the extent it has been materially prejudiced by the failure to give notice. The indemnifying party will be entitled to participate in the defense of any claim, action, suit or proceeding as to which indemnification is being sought, and if the indemnifying party acknowledges in writing the obligation to indemnify the party against whom the claim or action is brought, the indemnifying party may (but will not be required to) assume the defense against the claim, action, suit or proceeding with counsel satisfactory to it. After an indemnifying party notifies an indemnified party that the indemnifying party wishes to assume the defense of a claim, action, suit or proceeding, the indemnifying party will not be liable for any legal or other expenses incurred by the indemnified party in connection with the defense against the claim, action, suit or proceeding except that if, in the opinion of counsel to the indemnifying party, it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent the indemnifying party and one or more of the indemnified parties. In such event, the indemnifying party will pay the reasonable fees and expenses of not more than one separate counsel for all of the indemnified parties. Each indemnified party, as a condition to receiving indemnification as provided in Section 8.1, will cooperate in all reasonable respects with the indemnifying party in the defense of any action or claim as to which indemnification is sought. No indemnifying party will be liable for any settlement of any action effected without its prior written consent. No indemnifying party will, without the prior written consent of the indemnified party, effect any settlement of a pending or threatened action with respect to which an indemnified party is, or is informed that it may be, made a party and for which it would be entitled to indemnification, unless the settlement includes an unconditional release of the indemnified party from all liability and claims which are the subject matter of the pending or threatened action.

If for any reason the indemnification provided for in this Agreement is not available to, or is not sufficient to hold harmless, an indemnified party in respect of any loss or liability referred to in Section 8.1 as to which such indemnified party is entitled to indemnification thereunder, each indemnifying party shall, in lieu of indemnifying the indemnified party, contribute to the amount paid or payable by the indemnified party as a result of such loss or liability, (i) in the proportion which is appropriate to reflect the relative benefits received by the indemnifying party, on the one hand, and by the indemnified party, on the other hand, from the sale of Shares which is the subject of the claim, action, suit or proceeding which resulted in the loss or liability or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above, but also the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, with respect to the statements or omissions which are the subject of the claim, action, suit or proceeding that resulted in the loss or liability, as well as any other relevant equitable considerations.

The remedies provided for in Section 8.1 and this Section 8.2 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified person at law or in equity.

ARTICLE IX

Section 9.6 Headings; Construction.

Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Agreement instead of just the provision in which they are found. The parties agree that each of them and their respective counsel has reviewed and had an opportunity to revise this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement.

The assignment by a party to this Agreement of any rights hereunder shall not affect the obligations of such party under this Agreement.

Section 9.8 Governing Law.

In the event any signature is delivered by facsimile, digital or electronic transmission, such transmission shall constitute delivery of the manually executed original and the party using such means of delivery shall thereafter cause four additional executed signature pages to be physically delivered to the other parties within five days of the execution and delivery hereof. Failure to provide or delay in the delivery of such additional executed signature pages shall not adversely affect the efficacy of the original delivery.

The Investor shall have the right to approve, prior to issuance or filing, any press release, Commission filing or any other public disclosure made by or on behalf of the Company relating to the Investor, its purchases hereunder or any aspect of this Agreement or the transactions contemplated hereby (unless the same disclosure has been previously reviewed and approved by the Investor); provided, however, that except as otherwise provided in this Agreement, the Company shall be entitled, without the prior approval of the Investor, to make any press release or other public disclosure (including any filings with the Commission) with respect thereto as is required by applicable law and regulations (including the regulations of the Trading Market), so long as prior to making any such press release or other public disclosure, if reasonably practicable, the Company and its counsel shall have provided the Investor and its counsel with a reasonable opportunity to review and comment upon, and shall have consulted with the Investor and its counsel on the form and substance of, such press release or other disclosure.

Section 9.13 No Third Party Beneficiaries. Except as expressly provided in Article VIII, this Agreement is intended only for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person.
