Based on such information as the Investor has deemed appropriate and the Investor has independently made its own analysis and decision to purchase the Securities.

6. Registration Rights.

(a) Issuer agrees that, within thirty (30) business days following the date hereof (such deadline, the “Filing Deadline”), Issuer will submit to or file with the SEC a registration statement for a shelf registration on Form S-1 (the “Registration Statement”) covering the resale of the Shares acquired by the Investor pursuant to this Subscription Agreement and the Warrant Shares that are eligible for registration (determined as of two business days prior to such submission or filing) (the “Registrable Shares”) and Issuer shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 90th calendar day following the date hereof if the SEC notifies Issuer that it will “review” the Registration Statement (including a limited review) and (ii) the 10th business day after the date Issuer is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”); provided, however, that Issuer’s obligations to include the Registrable Shares in the Registration Statement are contingent upon Investor furnishing in writing to Issuer such information regarding Investor or its permitted assigns, the securities of Issuer held by Investor and the intended method of disposition of the Registrable Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by Issuer to effect the registration of the Registrable Shares at least five (5) business days in advance of the expected filing date of the Registration Statement, and Investor shall execute such documents in connection with such registration as Issuer may reasonably request that are customary of a selling stockholder in similar situations, including providing that Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement, if applicable, during any customary blackout or similar period or as permitted hereunder; provided that Investor shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable Shares. Notwithstanding the foregoing, if the SEC prevents Issuer from including any or all of the shares proposed to be registered under a Registration Statement due to limitations on the use of Rule 415 under the Securities Act for the resale of the Shares pursuant to this Section 6 by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as is permitted to be registered by the SEC. In such event, the number of Shares to be registered for each selling stockholder named in such Registration Statement shall be reduced pro rata among all such selling stockholders. In the event Issuer amends the Registration Statement in accordance with the foregoing, Issuer will use its commercially reasonable efforts to file with the SEC, as promptly as allowed by the SEC, one or more registration statements to register the resale of those Registrable Shares that were not registered on the initial Registration Statement, as so amended. For as long as the Investor holds Shares, Issuer will use commercially reasonable efforts to file all reports for so long as the condition in Rule 144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Shares pursuant to Rule 144 of the Securities Act (in each case, when Rule 144 of the Securities Act becomes available to the Investor). Any failure by Issuer to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve Issuer of its obligations to file or effect the Registration Statement as set forth above in this Section 6.

(b) At its expense Issuer shall:

(i) except for such times as Issuer is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which Issuer determines to obtain, continuously effective with respect to Investor, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (A) Investor ceases to hold any Registrable Shares, (B) the date all Registrable Shares held by Investor may be sold without restriction under Rule 144, including, without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for Issuer to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (C) two (2) years from the date of effectiveness of the Registration Statement (the period of time during which Issuer is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”);

(ii) during the Registration Period, advise Investor, as expeditiously as practicable:

(1) when a Registration Statement or any amendment thereto has been filed with the SEC;

(2) after it shall receive notice or obtain knowledge thereof, of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3) of the receipt by Issuer of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(4) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, Issuer shall not, when so advising Investor of such events, provide Investor with any material, nonpublic information regarding Issuer other than to the extent that providing notice to Investor of the occurrence of the events listed in (1) through (4) above constitutes material, nonpublic information regarding Issuer;

(iii) during the Registration Period, use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) during the Registration Period, upon the occurrence of any event contemplated in Section 6(b)(ii)(4) above, except for such times as Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, Issuer shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(v) during the Registration Period, use its commercially reasonable efforts to cause all Registrable Shares to be listed on each securities exchange or market, if any, on which the shares of common stock issued by Issuer have been listed;

(vi) during the Registration Period, use its commercially reasonable efforts to allow the Investor to review disclosure regarding the Investor in the Registration Statement; and

(vii) during the Registration Period, otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investor, consistent with the terms of this Subscription Agreement, in connection with the registration of the Registrable Shares.

(c) Notwithstanding anything to the contrary in this Subscription Agreement, Issuer shall be entitled to delay the filing or effectiveness of, or suspend the use of, the Registration Statement if it determines that in order for the Registration Statement not to contain a material misstatement or omission, (i) an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (ii) the negotiation or consummation of a transaction by Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event Issuer’s board of directors reasonably believes would require additional disclosure by Issuer in the Registration Statement of material information that Issuer has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of Issuer’s board of directors to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (iii) in the good faith judgment of the majority of the members of Issuer’s board of directors, such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to Issuer and the majority of the members of Issuer’s board of directors concludes as a result that it is essential to defer such filing (each such circumstance, a “Suspension Event”); provided, however, that Issuer may not delay or suspend the Registration Statement on more than three occasions or for more than ninety (90) consecutive calendar days, or more than one hundred and twenty (120) total calendar days in each case during any twelve-month period. Upon receipt of any written notice from Issuer of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances under which they were made, in the case of the prospectus) not misleading, Investor agrees that (i) it will immediately discontinue offers and sales of the Registrable Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Investor receives copies of a supplemental or amended prospectus (which Issuer agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by Issuer that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by Issuer unless otherwise required by law or subpoena. If so directed by Issuer, Investor will deliver to Issuer or, in Investor’s sole discretion destroy, all copies of the prospectus covering the Registrable Shares in Investor’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Shares shall not apply (A) to the extent Investor is required to retain a copy of such prospectus (1) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (2) in accordance with a bona fide pre-existing document retention policy or (B) to copies stored electronically on archival servers as a result of automatic data back-up.

(d) Indemnification.

(i) Issuer agrees to indemnify, to the extent permitted by law, Investor (to the extent a seller under the Registration Statement), its directors, officers and each person who controls Investor (within the meaning of the Securities Act or the Exchange Act), to the extent permitted by law, against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including reasonable and documented outside attorneys’ fees of one law firm (and one firm of local counsel)) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to Issuer by or on behalf of such Investor expressly for use therein.

(ii) In connection with any Registration Statement in which an Investor is participating, such Investor shall furnish (or cause to be furnished) to Issuer in writing such information and affidavits as Issuer reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify Issuer, its directors and officers and each person or entity who controls Issuer (within the meaning of the Securities Act or the Exchange Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission) in any information or affidavit so furnished in writing by on behalf of such Investor expressly for use therein; provided, however, that the liability of such Investor shall be several and not joint with any other investor and shall be in proportion to and limited to the net proceeds received by such Investor from the sale of Registrable Shares giving rise to such indemnification obligation.

(iii) Any person or entity entitled to indemnification herein shall (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (B) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(iv) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities.

(v) If the indemnification provided under this Section 6(d) from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the Investor shall be limited to the net proceeds received by such Investor from the sale of Registrable Shares giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 6(d)(i), (ii) and (iii) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 6(d)(v) from any person or entity who was not guilty of such fraudulent misrepresentation.

7. Rights of Participation. Until September 18, 2025, the Issuer shall not issue in a single transaction or in a series of related transactions (each such transaction or series of transactions, an “Issuance”) additional shares of Common Stock or equity securities convertible into or exchangeable or exercisable for shares of Common Stock (“Applicable Equity Securities”) other than (i) Applicable Equity Securities issued upon the exchange, exercise or conversion of options, warrants or other securities exchangeable or exercisable for or convertible into Applicable Equity Securities in accordance with the terms thereof, (ii) Applicable Equity Securities issued in connection with any unit split, dividend or recapitalization of Applicable Equity Securities, (iii) Applicable Equity Securities issued as consideration pursuant to the acquisition of, or investment in, another corporation, limited liability company, partnership or other business or entity or the acquisition of any assets thereof (whether through a purchase of securities, merger, consolidation, purchase of assets or otherwise), including, without limitation, joint ventures and strategic alliances, (iv) Applicable Equity Securities issued to credit financing sources in connection with a debt financing of the Issuer or any amendment, modification or restructuring thereof, (v) Applicable Equity Securities issued to employees, officers, directors or consultants of, or other providers of services to, the Issuer or any of its subsidiaries or (vi) Applicable Equity Securities issued in an Issuance in which the net proceeds to the Issuer from such Issuance do not exceed $10 million, unless, in each case, the Issuer notifies the Investor in writing of such Issuance (which notice may be sent by the Issuer prior to or after the completion of the applicable Issuance) (an “Issuance Notice”) and grants to the Investor the right (the “Right”) to subscribe for and purchase additional Applicable Equity Securities at the same price and upon the same terms and conditions (including, in the event such Applicable Equity Securities are or were issued as a unit together with other Applicable Equity Securities, the purchase of such other Applicable Equity Securities) as the proposed Issuance in an amount up to $2,000,000 (“Participation Right Securities”). The Investor may exercise all or any portion of the Right with respect to any Issuance by delivering to the Issuer within five (5) business days of the delivery by the Issuer of the Issuance Notice relating to such Issuance: (i) written notice of the Investor’s election to exercise the Right, including confirmation of the portion of the Right to be exercised, with respect to such issuance (the “Exercise Notice”) and (ii) an accurate and complete copy of Schedule A, duly executed by the Investor, evidencing that the Investor is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act), an “accredited investor” (within the meaning of Rule 501(a) under the Securities Act) or an entity in which all of the equityholders are accredited investors within the meaning of Rule 501(a) under the Securities Act as of the date of the applicable Exercise Notice (together with the Exercise Notice, the “Exercise Documentation”). The closing of the purchase and sale pursuant to the exercise of such Right shall occur at the Issuer’s discretion no later than twenty (20) business days after the delivery of the Exercise Documentation by the Investor; provided, that the Issuer shall not be required to issue Participation Right Securities to the Investor unless and until the Investor has delivered to the Issuer the purchase price with respect thereto by wire transfer of United States dollars in immediately available funds to an account specified by the Issuer.

8. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement; provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach.

9. Investor Covenant. Investor hereby agrees that, from the date of this Subscription Agreement, none of Investor, its controlled affiliates, or any person or entity acting on behalf of Investor or any of its controlled affiliates or pursuant to any understanding with Investor or any of its controlled affiliates will engage in any Short Sales with respect to securities of Issuer prior to the one year anniversary of the date hereof (or the termination of this Subscription Agreement, if earlier). For purposes of this Section 9, “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.

10. Miscellaneous.

(a) Neither this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than the Securities acquired hereunder, if any) may be transferred or assigned; provided that the Investor may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on behalf of the Investor or an affiliate thereof); provided, further, that no such assignment shall relieve the Investor of its obligations hereunder.

(b) Issuer may request from the Investor such additional information as Issuer may deem necessary to evaluate the eligibility of the Investor to acquire the Securities and in connection with the inclusion of the Securities in the Registration Statement, and the Investor shall provide such information as may reasonably be requested.

(f) This Subscription Agreement may not be modified, waived or terminated except by an instrument in writing, signed by each of the parties hereto.

The rights and remedies of the parties and third party beneficiaries hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

(g) This Subscription Agreement (including the schedule hereto) and the Warrant constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof. This Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and assigns.

(h) Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns.

(i) If any provision of this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(j) This Subscription Agreement may be executed in one or more counterparts (including by electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(k) The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement, without posting a bond or undertaking and without proof of damages, to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Issuer shall be entitled to specifically enforce the Investor’s obligations to fund the Subscription Amount and the provisions of the Subscription Agreement of which the Issuer is an express third party beneficiary, in each case, on the terms and subject to the conditions set forth herein.
