WHEREAS, the parties desire that, upon the terms and subject to the conditions and limitations set forth herein, the Company may issue and sell to the Investor, from time to time as provided herein, and the Investor shall purchase from the Company, up to the lesser of (a) $2,750,000 and (b) 19.99% of the Company’s outstanding shares of Common Stock as of the date of this Agreement (to the extent applicable under Section 2.4 hereof), unless (i) stockholder approval is obtained to issue more than such 19.99% or (ii) the price of applicable sales of Common Stock to the Investor under this Agreement equals or exceeds the lower of (A) the official Closing Sale Price on the NYSEA immediately preceding the delivery of the applicable Fixed Purchase notice, VWAP Purchase notice, or Additional VWAP Purchase notice to the Investor and (B) the average of the Closing Sale Prices of the Common Stock on the NYSEA for the five business days immediately preceding the delivery of such Fixed Purchase notice, VWAP Purchase notice or Additional VWAP Purchase Notice, as applicable (in each case plus an incremental amount to take into account the Commitment Shares), such that the sales of such Common Stock to the Investor would not count toward the 19.99% because they are “at market” under applicable NYSEA rules;

WHEREAS, in consideration for the Investor’s execution and delivery of this Agreement, the Company shall cause its Transfer Agent to issue to the Investor the Commitment Shares in accordance with the terms and subject to the conditions of this Agreement; and

WHEREAS, the parties hereto are concurrently entering into a Registration Rights Agreement in the form attached as Exhibit A hereto (the “Registration Rights Agreement”), pursuant to which the Company shall provide Investor with certain registration rights related to the shares issued under this Agreement, upon the terms and subject to the conditions set forth therein.

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

ARTICLE I

Section 1.2. Closing Date; Settlement Dates.

ARTICLE II
PURCHASE TERMS

Subject to the satisfaction or (to the extent permitted by applicable law) waiver 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 Purchases. Upon the initial satisfaction of all of the conditions set forth in set forth in Section 6.2, (the “Commencement” and the date of initial satisfaction of all of such conditions, the “Commencement Date”) and from time to time thereafter, subject to the satisfaction of all of the conditions set forth in Section 6.3, and on any business day selected by the Company where the Closing Sale Price on the applicable national market, or quotation service, is equal to or greater than $0.20, the Company shall have the right, but not the obligation, to direct the Investor, by its delivery to the Investor of a Fixed Purchase Notice, to purchase a Fixed Purchase Share Amount, not to exceed the applicable Fixed Purchase Maximum Amount (calculated as of the applicable Fixed Purchase Date), at the applicable Fixed Purchase Price therefor on the applicable Fixed Purchase Date in accordance with this Agreement (each such purchase a “Fixed Purchase”); provided, however, that the Investor’s committed obligation under any single Fixed Purchase shall not exceed $50,000 (provided that all shares of Common Stock in respect of all prior Fixed Purchases, VWAP Purchases and Additional VWAP Purchases shall have been delivered to the Investor via DWAC). If the Company delivers any Fixed Purchase Notice directing the Investor to purchase a Fixed Purchase Share Amount in excess of the applicable Fixed Purchase Maximum Amount (calculated as of the applicable Fixed Purchase Date), such Fixed Purchase Notice shall be void ab initio to the extent of the amount by which the Fixed Purchase Share Amount set forth in such Fixed Purchase Notice exceeds such applicable Fixed Purchase Maximum Amount, and the Investor shall have no obligation to purchase such excess Shares in respect of such Fixed Purchase Notice; provided, however, that the Investor shall remain obligated to purchase the applicable Fixed Purchase Maximum Amount in such Fixed Purchase. The Company may deliver a Fixed Purchase Notice, in the Form attached hereto as Annex 2.1, to the Investor as often as every Trading Day, so long as (i) the Closing Sale Price of the Common Stock on such Trading Day is not less than $0.20 and (ii) all Shares subject to all prior Fixed Purchase Notices, VWAP Purchase Notices and Additional VWAP Purchase Notices (as applicable) have theretofore been received by the Investor as DWAC Shares. Since delivery of a Fixed Purchase Notice is made by the Company after market close on the applicable Fixed Purchase Date, the Fixed Purchase Price is determined and fixed at the time the Company delivers the Fixed Purchase to the Investor.

Section 2.2. VWAP Purchases. Upon the initial satisfaction of all of the conditions set forth in set forth in Section 6.2, on the Commencement Date and from time to time thereafter, and on any business day selected by the Company where the Closing Sale Price on the applicable national market, or quotation service is equal to or greater than $0.20, subject to the satisfaction of all of the conditions set forth in Section 6.3, in addition to purchases of Shares as described in Section 2.1, the Company shall also have the right, but not the obligation, to direct the Investor, by its delivery to the Investor of a VWAP Purchase Notice, to purchase the applicable VWAP Purchase Share Amount, not to exceed the applicable VWAP Purchase Maximum Amount, at the applicable VWAP Purchase Price therefor on the applicable VWAP Purchase Date in accordance with this Agreement (each such purchase, a “VWAP Purchase”); provided, however, that the Investor’s aggregate committed obligation under a VWAP Purchase and all Additional VWAP Purchases shall not exceed $1,000,000 in the aggregate for such VWAP Purchase and all such Additional VWAP Purchases, collectively. The Company may deliver VWAP Purchase Notice, in the Form attached hereto as Annex 2.2, to the Investor only (i) on a Trading Day on which the Company also properly submitted a Fixed Purchase Notice providing for a Fixed Purchase of an amount of Shares not less than the applicable Fixed Purchase Maximum Amount (calculated as of the applicable Fixed Purchase Date) and (ii) if all Shares subject to all prior Fixed Purchase Notices, VWAP Purchase Notices, and Additional VWAP Purchase Notices (as applicable) have theretofore been received by the Investor as DWAC Shares. The Investor is obligated to accept each VWAP Purchase Notice prepared and delivered by the Company in accordance with the terms of and subject to the satisfaction of the conditions contained in this Agreement. If the Company delivers any VWAP Purchase Notice directing the Investor to purchase a VWAP Purchase Share Amount in excess of the applicable VWAP Purchase Maximum Amount that the Company is then permitted to include in such VWAP Purchase Notice, such VWAP Purchase Notice shall be void ab initio to the extent of the amount by which the VWAP Purchase Share Amount set forth in such VWAP Purchase Notice exceeds such applicable VWAP Purchase Maximum Amount, and the Investor shall have no obligation to purchase such excess Shares in respect of such VWAP Purchase Notice; provided, however, that the Investor shall remain obligated to purchase the applicable VWAP Purchase Maximum Amount in such VWAP Purchase At or prior to 9:30 a.m., New York City time, on the Trading Day immediately following the VWAP Purchase Date for each VWAP Purchase, the Investor shall provide to the Company a written confirmation of such VWAP Purchase setting forth the applicable VWAP Purchase Share Amount and VWAP Purchase Price for such VWAP Purchase (each, a “VWAP Purchase Confirmation”).

Section 2.3. Additional VWAP Purchases. Upon the initial satisfaction of all of the conditions set forth in set forth in Section 6.3 on the Commencement Date and from time to time thereafter, subject to the satisfaction of all of the conditions set forth in Section 6.3, in addition to purchases of Shares as described in Section 2.1 and Section 2.2, the Company shall also have the right, but not the obligation, to direct the Investor, by its delivery to the Investor of an Additional VWAP Purchase Notice, to purchase the applicable Additional VWAP Purchase Share Amount, not to exceed the applicable Additional VWAP Purchase Maximum Amount, at the applicable Additional VWAP Purchase Price therefor on the applicable Additional VWAP Purchase Date in accordance with this Agreement (each such purchase, an “Additional VWAP Purchase”); provided, however, that the Investor’s aggregate committed obligation under a VWAP Purchase and all Additional VWAP Purchases, the applicable Additional VWAP Purchase Date therefor is the same Trading Day as the applicable VWAP Purchase Date for such VWAP Purchase, shall not exceed $1,000,000 in the aggregate for such VWAP Purchase and all such Additional VWAP Purchases, collectively. The Company may deliver an Additional VWAP Purchase Notice, in the Form attached hereto as Annex 2.3, to the Investor only (i) on a Trading Day that is also the VWAP Purchase Date for a VWAP Purchase with respect to which the Company properly submitted to the Investor a VWAP Purchase Notice in accordance with this Agreement on the applicable Fixed Purchase Date for a Fixed Purchase of an amount of Shares not less than the applicable Fixed Purchase Maximum Amount (calculated as of the applicable Fixed Purchase Date) and (ii) if all Shares subject to all prior Fixed Purchase Notices, VWAP Purchase Notices, and Additional VWAP Purchase Notices, including, without limitation, all prior VWAP Purchases and Additional VWAP Purchases effected on the same Trading Day as the Additional VWAP Purchase Date on which the applicable Additional VWAP Purchase is to be effected, as applicable, have theretofore been received by the Investor as DWAC Shares. The Investor is obligated to accept each Additional VWAP Purchase Notice prepared and delivered by the Company in accordance with the terms of and subject to the satisfaction of the conditions contained in this Agreement. If the Company delivers any Additional VWAP Purchase Notice directing the Investor to purchase an Additional VWAP Purchase Share Amount in excess of the applicable Additional VWAP Purchase Maximum Amount that the Company is then permitted to include in such Additional VWAP Purchase Notice, such Additional VWAP Purchase Notice shall be void ab initio to the extent of the amount by which the Additional VWAP Purchase Share Amount set forth in such Additional VWAP Purchase Notice exceeds such applicable Additional VWAP Purchase Maximum Amount, and the Investor shall have no obligation to purchase such excess Shares in respect of such Additional VWAP Purchase Notice; provided, however, that the Investor shall remain obligated to purchase the applicable Additional VWAP Purchase Maximum Amount in such Additional VWAP Purchase At or prior to 9:30 a.m., New York City time, on the Trading Day immediately following the Additional VWAP Purchase Date for each Additional VWAP Purchase, the Investor shall provide to the Company a written confirmation of such Additional VWAP Purchase setting forth the applicable Additional VWAP Purchase Share Amount and Additional VWAP Purchase Price for such Additional VWAP Purchase (each, an “Additional VWAP Purchase Confirmation”).

Section 2.4. Compliance with Rules of Trading Market.

(a) Share Issuance Restriction. The Company shall not issue or sell any shares of Common Stock pursuant to this Agreement, and the Investor shall not purchase or acquire any shares of Common Stock pursuant to this Agreement, to the extent that after giving effect thereto, the aggregate number of shares of Common Stock that would be issued pursuant to this Agreement and the transactions contemplated hereby, including the Commitment Shares, would exceed 6,567,409 (representing 19.99% of the shares of Common Stock issued and outstanding immediately prior to the execution of this Agreement), which number of shares shall be reduced, on a share-for-share basis, by the number of shares of Common Stock issued or issuable pursuant to any transaction or series of transactions that may be aggregated with the transactions contemplated by this Agreement under applicable rules of the Trading Market (such maximum number of shares of Common Stock issuable by the Company under this Agreement, the “Aggregate Limit”).

(b) General. The Company shall not issue or sell any shares of Common Stock pursuant to this Agreement if such issuance or sale would reasonably be expected to result in (A) a violation of the Securities Act or (B) a breach of the rules of the Trading Market. The provisions of this Section 2.4 shall be implemented in a manner otherwise than in strict conformity with the terms of this Section 2.4 only if necessary to ensure compliance with the Securities Act and the applicable rules of the Trading Market.

Section 2.5. Beneficial Ownership Limitation. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not issue or sell, and the Investor shall not purchase or acquire, any shares of Common Stock under this Agreement which, when aggregated with all other shares of Common Stock then beneficially owned by the Investor and its Affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder), would result in the beneficial ownership by the Investor of more than 4.99% of the outstanding shares of Common Stock (the “Beneficial Ownership Limitation”). Upon the written or oral request of the Investor, the Company shall promptly (but not later than the next business day on which the Transfer Agent is open for business) confirm orally or in writing to the Investor the number of shares of Common Stock outstanding as of the most recent date for which the Transfer Agent has such information. The Investor and the Company shall each cooperate in good faith in the determinations required under this Section 2.5 and the application of this Section 2.5. The Investor’s written certification to the Company of the applicability of the Beneficial Ownership Limitation, and the resulting effect thereof hereunder at any time, shall be conclusive with respect to the applicability thereof and such result absent manifest error. The provisions of this Section 2.5 shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2.5 to the extent necessary to properly give effect to the limitations contained in this Section 2.5.

Section 2.6. Commitment Shares. In consideration for the Investor’s execution and delivery of this Agreement, concurrently with the execution and delivery of this Agreement on the Closing Date, the Company shall deliver irrevocable instructions to its Transfer Agent to electronically issue to the Investor or its designee(s) the Commitment Shares, not including the Back End Commitment Shares, as DWAC Shares, such that they are credited to the Investor’s or its designee’s specified Deposit/Withdrawal at Custodian (“DWAC”) account with DTC under its Fast Automated Securities Transfer (FAST) Program not later than 4:00 p.m. (New York City time) on the Closing Date, and prior to the delivery of the initial Fixed Purchase Notice. The Commitment Shares, not including the Back End Commitment Shares, shall be included in the initial Prospectus Supplement to be freely tradable and transferable and without restriction on resale and without any stop transfer instructions maintained against the transfer thereof. Additionally, in further consideration for the Investor’s execution and delivery of this Agreement, upon the completion of a successful raise by the Company of a minimum of $2,750,000 from (i) this Agreement or (ii) another source, the Company shall deliver irrevocable instructions to its Transfer Agent to electronically issue to the Investor or its designee(s) the Back End Commitment Shares, as DWAC Shares, such that they are credited to the Investor’s or its designee’s specified DWAC account with DTC under its FAST Program not later than 4:00 p.m. (New York City time) on the closing of such capital raise. For the avoidance of doubt, all of the Commitment Shares, including the Back End Commitment Shares, shall be fully earned as of the Closing Date, regardless of whether any Fixed Purchases or VWAP Purchases are effected hereunder and regardless of any subsequent termination of this Agreement.

The Company and its officers and employees shall provide information on a reasonably timely basis and otherwise reasonably cooperate with the Investor in connection with any reasonable request by the Investor related to the Investor’s due diligence of the Company.

Subject to Section 7.3, this Agreement may be terminated at any time by the mutual written consent of the parties, effective as of the date of such mutual written consent unless otherwise provided in such written consent. Subject to Section 7.3, the Investor shall have the right to terminate this Agreement effective upon ten (10) Trading Days’ prior written notice to the Company in accordance with Section 9.4, if: (a) any condition, occurrence, state of facts or event constituting a Material Adverse Effect has occurred and is continuing; (b) a Fundamental Transaction shall have occurred; (c) the Initial Prospectus Supplement and any New Registration Statement is not filed by the applicable Filing Deadline therefor or declared effective by the Commission by the applicable Effectiveness Deadline (as defined in the Registration Rights Agreement) therefor, or the Company is otherwise in breach or default in any material respect under any of the other provisions of the Registration Rights Agreement, and, if such failure, breach or default is capable of being cured, such failure, breach or default is not cured within 10 Trading Days after notice of such failure, breach or default is delivered to the Company pursuant to Section 9.4; (d) while a Registration Statement, or any post-effective amendment thereto, is required to be maintained effective pursuant to the terms of the Registration Rights Agreement and the Investor holds any Registrable Securities, the effectiveness of such Registration Statement, or any post-effective amendment thereto, lapses for any reason (including, without limitation, the issuance of a stop order by the Commission) or such Registration Statement or any post-effective amendment thereto, the Prospectus contained therein or any Prospectus Supplement thereto otherwise becomes unavailable to the Investor for the resale of all of the Registrable Securities included therein in accordance with the terms of the Registration Rights Agreement, and such lapse or unavailability continues for a period of 20 consecutive Trading Days, other than due to acts of the Investor; (e) trading in the Common Stock on the Trading Market (or if the Common Stock is then listed on an Eligible Market, trading in the Common Stock on such Eligible Market) shall have been suspended and such suspension continues for a period of three (3) consecutive Trading Days; or (f) the Company is in material breach or default of this Agreement, and, if such breach or default is capable of being cured, such breach or default is not cured within 10 Trading Days after notice of such breach or default is delivered to the Company (as applicable) pursuant to Section 9.4. Unless notification thereof is required elsewhere in this Agreement (in which case such notification shall be provided in accordance with such other provision), the Company shall promptly (but in no event later than 24 hours) notify the Investor (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 (or if the Common Stock is then listed on an Eligible Market, the rules and regulations of such Eligible Market), the Company shall publicly disclose such information in accordance with Regulation FD and the applicable rules and regulations of the Trading Market, or the applicable rules and regulations of such Eligible Market, as applicable) upon becoming aware of any of the events set forth in the immediately preceding sentence.

Section 7.3. Effect of Termination. In the event of termination by the Company or the Investor (other than by mutual termination) pursuant to Section 7.2, written notice thereof shall forthwith be given to the other party as provided in Section 9.4 and the transactions contemplated by this Agreement shall be terminated without further action by either party. If this Agreement is terminated as provided in Section 7.1 or Section 7.2, this Agreement shall become void and of no further force and effect, except that (i) the provisions of Article IV (Representations and Warranties of the Company), Article VIII (Indemnification), Article IX (Miscellaneous) and this Article VII (Termination) shall remain in full force and effect indefinitely notwithstanding such termination, and, (ii) so long as the Investor owns any Securities, the covenants and agreements of the Company contained in Article V (Covenants) shall remain in full force and notwithstanding such termination for a period of six (6) months following such termination. Notwithstanding anything in this Agreement to the contrary, no termination of this Agreement by any party shall (i) become effective prior to the first Trading Day immediately following the settlement date related to any pending Fixed Purchase Notice, any pending VWAP Purchase Notice, or any pending Additional VWAP Purchase Notice (as applicable) that has not been fully settled in accordance with the terms and conditions of this Agreement (it being hereby acknowledged and agreed that no termination of this Agreement shall limit, alter, modify, change or otherwise affect any of the parties’ respective rights or obligations under the Transaction Documents with respect to any pending Fixed Purchase, pending VWAP Purchase, and pending Additional VWAP Purchase (as applicable), and that the parties shall fully perform their respective obligations with respect to any such pending Fixed Purchase, any such pending VWAP Purchase, and any such pending Additional VWAP Purchase (as applicable) under the Transaction Documents, provided all of the conditions to the settlement thereof set forth in Article VI are timely satisfied), (ii) limit, alter, modify, change or otherwise affect the parties’ respective rights or obligations under the Registration Rights Agreement, all of which shall survive any such termination, (iii) affect the Investor Expense Reimbursement paid to the Investor, all of which shall be non-refundable when paid as of the Closing Date pursuant to Section 9.1(i), regardless of whether any Fixed Purchases, VWAP Purchases, or Additional VWAP Purchases are made or settled hereunder or any subsequent termination of this Agreement, or (iv) affect any Commitment Shares previously issued or delivered, or any rights of any holder thereof, it being hereby acknowledged and agreed that all of the Commitment Shares shall be fully earned as of the Closing Date, regardless of whether any Fixed Purchases, VWAP Purchases or Additional VWAP Purchases are made or settled hereunder or any subsequent termination of this Agreement. Nothing in this Section 7.3 shall be deemed to release the Company or the Investor from any liability for any breach or default under this Agreement or any of the other Transaction Documents to which it is a party, or to impair the respective rights of the Company and the Investor to compel specific performance by the other party of its obligations under the Transaction Documents to which it is a party.

ARTICLE VIII
INDEMNIFICATION

Section 8.1. Indemnification of Investor. In consideration of the Investor’s execution and delivery of this Agreement and acquiring the Securities hereunder and in addition to all of the other respective obligations of the Company under the Transaction Documents to which it is a party, subject to the provisions of this Section 8.1, the Company shall indemnify and hold harmless the Investor, each of its directors, officers, shareholders, members, partners, employees, representatives, agents and advisors (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding the lack of such title or any other title), 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), and the respective directors, officers, shareholders, members, partners, employees, representatives, agents and advisors (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding the lack of such title or any other title) of such controlling Persons (each, an “Investor Party”), from and against all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses (including all judgments, amounts paid in settlement, court costs, reasonable attorneys’ fees and costs of defense and investigation) (collectively, “Damages”) that any Investor Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents to which it is a party or (b) any action, suit, claim or proceeding (including for these purposes a derivative action brought on behalf of the Company) instituted against such Investor Party arising out of or resulting from the execution, delivery, performance or enforcement of the Transaction Documents, other than claims for indemnification within the scope of Section 6 of the Registration Rights Agreement; provided, however, that (x) the foregoing indemnity shall not apply to any Damages to the extent, but only to the extent, that such Damages resulted directly and primarily from any acts or failures to act, undertaken or omitted to be taken by such Investor Party through its fraud, bad faith, gross negligence, or willful or reckless misconduct.

The Company shall reimburse any Investor Party promptly upon demand (with accompanying presentation of documentary evidence) for all legal and other costs and expenses reasonably incurred by such Investor Party in connection with (i) any action, suit, claim or proceeding, whether at law or in equity, to enforce compliance by the Company with any provision of the Transaction Documents to which it is a party or (ii) any other any action, suit, claim or proceeding, whether at law or in equity, with respect to which it is entitled to indemnification under this Section 8.1; provided that the Investor shall promptly reimburse the Company for all such legal and other costs and expenses to the extent a court of competent jurisdiction determines that any Investor Party was not entitled to such reimbursement.

An Investor Party’s right to indemnification or other remedies based upon the representations, warranties, covenants and agreements of the Company set forth in the Transaction Documents to which it is a party shall not in any way be affected by any investigation or knowledge of such Investor Party. Such representations, warranties, covenants and agreements shall not be affected or deemed waived by reason of the fact that an Investor Party knew or should have known that any representation or warranty might be inaccurate or that the Company failed to comply with any agreement or covenant. Any investigation by such Investor Party shall be for its own protection only and shall not affect or impair any right or remedy hereunder.

To the extent that the foregoing joint and several undertakings by the Company set forth in this Section 8.1 may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Damages which is permissible under Applicable Law.

Section 8.2. Indemnification Procedures. Promptly after an Investor Party receives notice of a claim or the commencement of an action for which the Investor Party intends to seek indemnification under Section 8.1, the Investor Party will notify the Company in writing of the claim or commencement of the action, suit or proceeding; provided, however, that failure to notify the Company will not relieve the Company from liability under Section 8.1, except to the extent it has been materially prejudiced by the failure to give notice. The Company 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 Company acknowledges in writing the obligation to indemnify the Investor Party against whom the claim or action is brought, the Company may (but will not be required to) assume the defense against the claim, action, suit or proceeding with counsel satisfactory to it. After the Company notifies the Investor Party that the Company wishes to assume the defense of a claim, action, suit or proceeding, the Company will not be liable for any further legal or other expenses incurred by the Investor Party in connection with the defense against the claim, action, suit or proceeding except that if, in the opinion of counsel to the Investor Party, it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and such Investor Party. In such event, the Company will pay the reasonable fees and expenses of no more than one separate counsel for all such Investor Parties promptly as such fees and expenses are incurred. Each Investor Party, as a condition to receiving indemnification as provided in Section 8.1, will cooperate in all reasonable respects with the Company in the defense of any action or claim as to which indemnification is sought. The Company will not be liable for any settlement of any action effected without its prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned. The Company will not, without the prior written consent of the Investor Party, effect any settlement of a pending or threatened action with respect to which an Investor 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 Investor Party from all liability and claims which are the subject matter of the pending or threatened action.

The remedies provided for in this Article VIII are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Investor Party at law or in equity.

ARTICLE IX
MISCELLANEOUS

Section 9.1. Certain Fees and Expenses; Commitment Shares; Commencement Irrevocable Transfer Agent Instructions.

(i) Certain Fees and Expenses. Each party shall bear its own fees and expenses related to the transactions contemplated by this Agreement; provided, however, that immediately following the initial Settlement hereunder, the Company shall pay, by wire transfer of immediately available funds to an account designated by the Investor, an amount equal to $25,000 to be applied against the Investor’s reasonable out-of-pocket expenses, including the legal fees and disbursements of the Investor’s legal counsel, incurred by the Investor in connection with the preparation, negotiation, execution and delivery of the Transaction Documents by the Investor and its due diligence investigation of the Company (such amount, the “Investor Expense Reimbursement”). For the avoidance of doubt, the Investor Expense Reimbursement, shall be non-refundable when paid as of the Closing Date, regardless of whether any Fixed Purchases, VWAP Purchases or Additional VWAP Purchases are made or settled hereunder or any subsequent termination of this Agreement. The Company shall pay all U.S. federal, state and local stamp and other similar transfer and other taxes and duties levied in connection with issuance of the Securities pursuant hereto.

(ii) Commitment Shares. In consideration for the Investor’s execution and delivery of this Agreement, concurrently with the execution and delivery of this Agreement on the Closing Date, the Company shall deliver irrevocable instructions to the Transfer Agent to issue to the Investor, not later than 4:00 p.m. (New York City time) on the Trading Day immediately following the Closing Date, one or more certificate(s) or book-entry statement(s) representing the Commitment Shares, not including the Back End Commitment Shares, payable as of the Closing Date, in the name of the Investor or its designee (in which case such designee name shall have been provided to the Company prior to the Closing Date). Such certificate or book-entry statement shall be delivered to the Investor by overnight courier at its address set forth in Section 9.4. Additionally, in further consideration for the Investor’s execution and delivery of this Agreement, upon the completion of a successful raise by the Company of a minimum of $2,750,000 from (i) this Agreement or (ii) another source, the Company shall deliver irrevocable instructions to its Transfer Agent to electronically issue to the Investor or its designee(s) the Back End Commitment Shares, as DWAC Shares, such that they are credited to the Investor’s or its designee’s specified DWAC account with DTC under its FAST Program not later than 4:00 p.m. (New York City time) on the closing of such capital raise. For the avoidance of doubt, all of the Commitment Shares shall be fully earned as of the Closing Date, and whether any Fixed Purchases, VWAP Purchases or Additional VWAP Purchases are made or settled hereunder or any subsequent termination of this Agreement. Upon issuance, the Commitment Shares shall constitute “restricted securities” as such term is defined in Rule 144(a)(3) under the Securities Act and, subject to the provisions of subsection (iv) of this Section 9.1, the certificate or book-entry statement representing the Commitment Shares shall bear the restrictive legend set forth below in subsection (iii) of this Section 9.1. The Commitment Shares shall constitute Registrable Securities and shall be included in the Initial Prospectus Supplement and any post-effective amendment thereto, and the Prospectus included therein and, if necessary to register the resale thereof by the Investor under the Securities Act, in any New Registration Statement and any post-effective amendment thereto, in each case in accordance with this Agreement and the Registration Rights Agreement.

(iii) Irrevocable Transfer Agent Instructions; Notice of Effectiveness. On the Commencement Date, the Company shall cause the Transfer Agent to credit the Investor’s or its designee’s account at DTC as DWAC Shares such number of shares of Common Stock equal to the number of Commitment Shares, not including the Back End Commitment Shares issued to the Investor pursuant to Section 9.1(ii). The Company shall take all actions to carry out the intent and accomplish the purposes of the immediately preceding sentence, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions to the Transfer Agent, and any successor transfer agent of the Company, as may be requested from time to time by the Investor or necessary or desirable to carry out the intent and accomplish the purposes of the immediately preceding sentence. Upon the filing of the Initial Prospectus Supplement, the Company shall deliver or cause to be delivered to the Transfer Agent (and thereafter, shall deliver or cause to be delivered to any subsequent transfer agent of the Company), (i) irrevocable instructions executed by the Company and acknowledged in writing by the Transfer Agent (the “Commencement Irrevocable Transfer Agent Instructions”) and (ii) the notice of effectiveness in the form attached as an exhibit to the Registration Rights Agreement (the “Notice of Effectiveness”) relating to the Initial Prospectus Supplement executed by the Company’s outside counsel, in each case directing the Transfer Agent to issue to the Investor or its designee all of the Commitment Shares, not including the Back End Commitment Shares, as DWAC Shares in accordance with this Agreement and the Registration Rights Agreement. With respect to any post-effective amendment to the Initial Prospectus Supplement, any New Registration Statement or any post-effective amendment to any New Registration Statement, in each case declared effective by the Commission after the Commencement Date, the Company shall deliver or cause to be delivered to the Transfer Agent (and thereafter, shall deliver or cause to be delivered to any subsequent transfer agent of the Company) (i) irrevocable instructions in the form substantially similar to the Commencement Irrevocable Transfer Agent Instructions executed by the Company and acknowledged in writing by the Transfer Agent and (ii) the Notice of Effectiveness, in each case modified as necessary to refer to such Registration Statement or post-effective amendment and the Registrable Securities included therein. For the avoidance of doubt, all Shares and Commitment Shares to be issued from and after Commencement to or for the benefit of the Investor pursuant to this Agreement shall be issued to the Investor or its designee only as DWAC Shares. The Company represents and warrants to the Investor that, while this Agreement is effective, no instruction other than those referred to in this Section 9.1(iv) will be given by the Company to the Transfer Agent, or any successor transfer agent of the Company, with respect to the Shares and the Commitment Shares from and after Commencement, and the Shares and the Commitment Shares (as applicable) covered by the Initial Prospectus Supplement or any post-effective amendment thereof, or any New Registration Statement or post-effective amendment thereof, as applicable, shall otherwise be freely transferable on the books and records of the Company and no stop transfer instructions shall be maintained against the transfer thereof. The Company agrees that if the Company fails to fully comply with the provisions of this Section 9.1(iv) within three (3) Trading Days after the date on which the Investor has provided the deliverables referred to above that the Investor is required to provide to the Company or the Transfer Agent, the Company shall, at the Investor’s written instruction, purchase from the Investor all shares of Common Stock purchased or acquired by the Investor pursuant to this Agreement that contain the restrictive legend referred to in Section 9.1(iii) hereof (or any similar restrictive legend) at the greater of (i) the purchase price paid for such shares of Common Stock (as applicable) and (ii) the Closing Sale Price of the Common Stock on the date of the Investor’s written instruction.

Section 9.2. Specific Enforcement, Consent to Jurisdiction, Waiver of Jury Trial.

(i) The Company and the Investor acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Company, on the one hand, and the Investor, on the other hand, shall be entitled to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement by the other party and to enforce specifically the terms and provisions hereof (without the necessity of showing economic loss and without any bond or other security being required), this being in addition to any other remedy to which either party may be entitled by law or equity.

(ii) Each of the Company and the Investor (a) hereby irrevocably submits to the jurisdiction of the U.S. District Court and other courts of the United States sitting in the State of New York for the purposes of any suit, action or proceeding arising out of or relating to this Agreement, and (b) hereby waives, and agrees not to assert in any such suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such court, that the suit, action or proceeding is brought in an inconvenient forum or that the venue of the suit, action or proceeding is improper. Each of the Company and the Investor consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing in this Section 9.2 shall affect or limit any right to serve process in any other manner permitted by law.

(iii) EACH OF THE COMPANY AND THE INVESTOR HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR DISPUTES RELATING HERETO. EACH OF THE COMPANY AND THE INVESTOR (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.2.

The Transaction Documents set forth the entire agreement and understanding of the parties with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements, negotiations and understandings between the parties, both oral and written, with respect to such matters. There are no promises, undertakings, representations or warranties by either party relative to subject matter hereof not expressly set forth in the Transaction Documents. The Disclosure Schedule and all exhibits to this Agreement are hereby incorporated by reference in, and made a part of, this Agreement as if set forth in full herein.

For the avoidance of doubt, the Company shall not be required to submit for review any such disclosure (i) contained in periodic reports filed with the Commission under the Exchange Act if it shall have previously provided the same disclosure to the Investor or its counsel for review in connection with a previous filing or (ii) any Prospectus Supplement if it contains disclosure that does not reference the Investor, its purchases hereunder or any aspect of the Transaction Documents or the transactions contemplated thereby.

Section 9.15. Severability. The provisions of this Agreement are severable and, in the event that any court of competent jurisdiction shall determine that any one or more of the provisions or part of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision or part of a provision of this Agreement, and this Agreement shall be reformed and construed as if such invalid or illegal or unenforceable provision, or part of such provision, had never been contained herein, so that such provisions would be valid, legal and enforceable to the maximum extent possible.
