Zenas has agreed to pay InnoCare an upfront cash payment of $35 million and also issued to InnoCare 5,000,000 shares (the “InnoCare Upfront Shares”) of its common stock, par value $0.0001 per share (“Common Stock”), representing approximately 10.6% of Zenas’s issued and outstanding Common Stock as of October 7, 2025, after giving effect to the issuance to InnoCare, and approximately 9.3% of Zenas’s issued and outstanding Common Stock after giving effect to the further issuance of the PIPE Shares (as defined below).

 

Zenas has agreed to make a one-time, cash payment of $25 million and issue 2,000,000 shares of Common Stock (the “InnoCare Near-Term Milestone Shares” and, together with the InnoCare Upfront Shares, the “InnoCare Shares”) upon the earlier of (i) Zenas’ initiation of a Phase 3 clinical trial for orelabrutinib in any indication other than primary progressive MS, and (ii) March 31, 2026, upon the occurrence of certain specified events (the “Orelabrutinib Near-Term Milestone”). Additionally, Zenas has agreed to make one-time, potential near-term milestone payments of $20 million each, upon the achievement of certain regulatory milestones for ZB021 and ZB022.

Each party has customary termination rights, including for uncured material breach, insolvency, patent challenge, or, in the case of Zenas, for convenience.

 

The foregoing description of the InnoCare License Agreement does not purport to be complete and is qualified in its entirety by reference to the InnoCare License Agreement, a copy of which the Company will file as an exhibit to its Annual Report on Form 10-K for the year ending December 31, 2025.

 

InnoCare Subscription Agreement and Registration Rights Agreement

 

On October 7, 2025, in connection with the InnoCare License Agreement described in Item 1.01 above, Zenas issued the InnoCare Upfront Shares (the “InnoCare Private Placement”), pursuant to the terms of a Subscription Agreement between InnoCare and Zenas (the “InnoCare Subscription Agreement”) in a private placement transaction. The InnoCare Subscription Agreement also provides that the Company will issue the Near-Term Milestone Shares upon the occurrence of the Orelabrutinib Near-Term Milestone. The InnoCare Subscription Agreement provides that InnoCare may not transfer any of the InnoCare Shares until October 7, 2026, and thereafter may not transfer InnoCare Shares during any one month in an amount the exceeds the greater of (i) one percent of the outstanding Common Stock as most recently reported by Zenas publicly and (ii) the average weekly reported volume of trading in the Common Stock during the four preceding calendar weeks. The foregoing restrictions will not apply to transfers to an affiliate of InnoCare, to Zenas or in connection with a change of control of Zenas approved by board of directors of Zenas.

 

In connection with the InnoCare Private Placement, the Company and InnoCare also entered into a Registration Rights Agreement on October 7, 2025 (the “InnoCare Registration Rights Agreement”). Pursuant to the terms of the InnoCare Registration Rights Agreement, the Company is obligated (i) to prepare and file with the Securities and Exchange Commission (the “SEC”) prior to October 7, 2026 a registration statement (the “InnoCare Registration Statement”) to register for resale the InnoCare Shares, and (ii) to use its reasonable best efforts to cause the Registration Statement to be declared effective by the SEC as soon as practicable thereafter.

 

The InnoCare Subscription Agreement contains customary representations, warranties and covenants that were made solely for the benefit of the parties to the InnoCare Subscription Agreement. Such representations, warranties and covenants (i) are intended as a way of allocating risk between the parties to the InnoCare Subscription Agreement and not as statements of fact, and (ii) may apply standards of materiality in a way that is different from what may be viewed as material by stockholders of, or other investors in, the Company. Accordingly, the InnoCare Subscription Agreement is included with this Current Report on Form 8-K only to provide investors with information regarding the terms of transaction and not to provide investors with any other factual information regarding the Company. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the InnoCare Subscription Agreement, which subsequent information may or may not be fully reflected in public disclosures.

 

The foregoing descriptions of the InnoCare Subscription Agreement and the InnoCare Registration Rights Agreement do not purport to be complete and are qualified in their entirety by reference to the Subscription Agreement and the Registration Rights Agreement, which are filed as Exhibit 10.1 and Exhibit 10.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

On October 7, 2025, the Company entered into a Securities Purchase Agreement (the "Securities Purchase Agreement") with (i) certain institutional and accredited investors (the "Institutional Investors") and (ii) certain directors and officers of the Company (the "Director and Officer Investors" and, together with the Institutional Investors, each, an "Investor" and, together, the "Investors"), pursuant to which the Company agreed to sell to (i) the Institutional Investors an aggregate of 6,261,893 shares of Common Stock (the "Institutional Investor PIPE Shares"), at a price of $19.00 per share, and (ii) the Director and Officer Investors an aggregate of 48,918 shares of Common Stock (the "Director and Officer Investor PIPE Shares" and, together with the Institutional Investor PIPE Shares, the "PIPE Shares") at a price of $20.85 per share, in each case in a private placement transaction (the "Investor Private Placement" and, together with the InnoCare Private Placement, the "Private Placements") for gross proceeds to the Company of approximately $120.0 million, before deducting placement agent fees and other expenses. The Closing of the Investor Private Placement is anticipated to occur on or about October 9, 2025 (the "PIPE Closing").

 

The Securities Purchase Agreement contains customary representations, warranties and covenants that were made solely for the benefit of the parties to the Securities Purchase Agreement. Such representations, warranties and covenants (i) are intended as a way of allocating risk between the parties to the Securities Purchase Agreement and not as statements of fact, and (ii) may apply standards of materiality in a way that is different from what may be viewed as material by stockholders of, or other investors in, the Company. Accordingly, the Securities Purchase Agreement is included with this Current Report on Form 8-K only to provide investors with information regarding the terms of transaction and not to provide investors with any other factual information regarding the Company. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Securities Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures.

 

PIPE Registration Rights Agreement

 

In connection with the Investor Private Placement, on October 7, 2025, the Company entered into a Registration Rights Agreement (the “PIPE Registration Rights Agreement”) with the Investors, pursuant to which the Company will prepare and file, within 15 days of the PIPE Closing and subject to certain allowable delays, an initial registration statement (the “PIPE Registration Statement”) with the SEC to register for resale the PIPE Shares.

On October 8, 2025, the Company issued a press release announcing the Agreement and the Private Placement. The Company is also hosting a conference call and webcast at 8 a.m. Eastern Time, on October 8, 2025.

 

A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and the presentation the Company intends to present on the conference call and webcast is furnished as Exhibit 99.2 to this Current Report on Form 8-K, and both are incorporated by reference herein. The exhibits furnished under Item 7.01 of this Current Report on Form 8-K shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Exchange Act or the Securities Act, regardless of any general incorporation language in such filing.

 

Item 8.01 Other Events

 

Recent Developments

 

Following entry into the InnoCare License Agreement, the Company’s pipeline currently comprises four programs it is developing initially for the treatment of immunology and inflammation diseases: (1) obexelimab, a bifunctional monoclonal antibody designed to bind both CD19 and  FcγRIIb, which are broadly present across the B cell lineage, in order to inhibit the activity of cells that are implicated in many autoimmune diseases without depleting them, (2) orelabrutinib, a highly selective and central nervous system-penetrant, oral small molecule Bruton’s Tyrosine Kinase inhibitor, (3) ZB021, an IL-17 AA/AF inhibitor and (4) ZB022, a brain-penetrant TYK2 inhibitor.

 

Additional information about the Company’s current pipeline can be found in Exhibit 99.3 to this Current Report on Form 8-K, which is incorporated by reference herein.

 

Company Cash Update

 

The Company estimates that, as of September 30, 2025, it had approximately $302 million in existing cash, cash equivalents and investments. During the three months ended September 30, 2025, a $5 million deposit was paid towards the $35 million upfront cash payment due to InnoCare. This estimated amount of cash, cash equivalents and investments as of September 30, 2025 is preliminary and is subject to completion of the Company’s financial closing procedures and has not been reviewed or audited by our independent auditors. Consequently, this amount may differ materially from the amount that will be reflected in the Company’s unaudited condensed consolidated balance sheet as of September 30, 2025.

 

As of the date of this Current Report on Form 8-K, after giving effect to the upfront cash consideration paid to InnoCare pursuant to the InnoCare License Agreement and the anticipated proceeds from the PIPE Transaction, the Company expects that its cash, cash equivalents and investments will be sufficient to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2026, and, assuming receipt from Royalty Pharma Investments 2019 ICAV (“Royalty Pharma”) of the potential $75 million milestone for the defined success criteria in the Phase 3 INDIGO trial of obexelimab pursuant to the Revenue Participation Right Purchase and Sale Agreement between the Company and Royalty Pharma, into the first quarter of 2027.

 

 

 

 

Forward Looking Statements

 

This Current Report on Form 8-K contains “forward-looking statements” which involve risks, uncertainties and contingencies, many of which are beyond the control of the Company, which may cause actual results, performance, or achievements to differ materially from anticipated results, performance, or achievements. All statements other than statements of historical facts contained in this Current Report on Form 8-K are forward-looking statements. In some cases, forward-looking statements can be identified by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. Forward-looking statements include, but are not limited to, statements concerning the Company’s milestones, expectations and intentions, including timing of the initiation of, results and data from clinical trials, including timing of reporting topline results from the INDIGO trial, and if successful, the timing of BLA submission, potential approval and commercial launch, the timing of reporting the 12-week and 24-week topline results from the MoonStone trial, the timing of the completion of enrollment and reporting the topline results from the SunStone trial, and if successful, the timing of initiating the Phase 3 trial in SLE, the timing of initiation of the Phase 3 clinical trial of orelabrutinib in patients with SPMS, the timing to submit an IND, and subject to IND clearance, the initiation of Phase 1 clinical studies of ZB021 and ZB022, the timing of initial patient data in ZB021; the potential benefits, development and commercialization of orelabrutinib and obexelimab and orelabrutinib’s potential as a franchise for progressive MS; the expansion of the Company’s pipeline; the expected PIPE Closing; the achievement of payment-triggering milestones pursuant to the InnoCare License Agreement and the Company’s cash guidance. The forward-looking statements in this Current Report on Form 8-K speak only as of the date of this Current Report on Form 8-K and are subject to a number of known and unknown risks, uncertainties and assumptions that could cause the Company’s actual results to differ materially from those anticipated in the forward-looking statements, including, but not limited to: the Company’s limited operating history, incurrence of substantial losses since the Company’s inception and anticipation of incurring substantial and increasing losses for the foreseeable future; the Company’s need for substantial additional financing to achieve the Company’s goals; the uncertainty of clinical development, which is lengthy and expensive, and characterized by uncertain outcomes, and risks related to additional costs or delays in completing, or failing to complete, the development and commercialization of the Company’s current product candidates or any future product candidates; delays or difficulties in the enrollment and dosing of patients in clinical trials; the impact of any significant adverse events or undesirable side effects caused by the Company’s product candidates; potential competition, including from large and specialty pharmaceutical and biotechnology companies, many of which already have approved therapies in the Company’s current indications; the Company’s ability to realize the benefits of the Company’s current or future collaborations or licensing arrangements and ability to successfully consummate future partnerships; the Company’s ability to obtain regulatory approval to commercialize any product candidate in the United States or any other jurisdiction, and the risk that any such approval may be for a more narrow indication than the Company seeks; the Company’s dependence on the services of the Company’s senior management and other clinical and scientific personnel, and the Company’s ability to retain these individuals or recruit additional management or clinical and scientific personnel; the Company’s ability to grow the Company’s organization, and manage the Company’s growth and expansion of the Company’s operations; risks related to the manufacturing of the Company’s product candidates, which is complex, and the risk that the Company’s third-party manufacturers may encounter difficulties in production; the Company’s ability to obtain and maintain sufficient intellectual property protection for the Company’s product candidates or any future product candidates the Company may develop; the Company’s reliance on third parties to conduct the Company’s preclinical studies and clinical trials; the Company’s compliance with the Company’s obligations under the licenses granted to the Company by others, for the rights to develop and commercialize the Company’s product candidates; significant political, trade, regulatory developments, including changes in relations between the U.S. and China; risks related to the operations of the Company’s suppliers, many of which are located outside of the United States, including the Company’s current sole contract manufacturing organization for drug substance and drug product, WuXi Biologics (Hong Kong) Limited, which is located in China; and other risks and uncertainties described in the section “Risk Factors” in the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, as well as other information the Company files with the Securities and Exchange Commission. The forward-looking statements in this Current Report on Form 8-K are inherently uncertain, speak only as of the date of this Current Report on Form 8-K and may prove incorrect. These statements are based upon information available to the Company as of the date of this Current Report on Form 8-K and while the Company believes such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that the Company has conducted an exhaustive inquiry into, or review of, all potentially available relevant information. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond the Company’s control, these forward-looking statements should not be relied upon as guarantees of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual future results, levels of activity, performance and events and circumstances could differ materially from those projected in the forward-looking statements. Moreover, the Company operates in an evolving environment. New risks and uncertainties may emerge from time to time, and management cannot predict all risks and uncertainties. Except as required by applicable law, the Company does not undertake to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

Before filing the Registration Statement, the Company shall furnish to the Investor a copy of the Registration Statement.

Such Registration Statement shall not include any shares of Common Stock or other securities for the account of any other holder of securities of the Company without the prior written consent of the Investor.

The Investor shall furnish all information reasonably requested by the Company and as shall be reasonably required in connection with any registration referred to in this Agreement.

(b)            The Company shall use its reasonable best efforts to have the Initial Registration Statement and any amendment declared effective by the Commission at the earliest possible date but no later than the earlier of the 75th calendar day following the initial filing date of the Initial Registration Statement if the Commission notifies the Company that it will “review” the Initial Registration Statement and (b) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Initial Registration Statement will not be “reviewed” or will not be subject to further review (the “Effectiveness Deadline”). The Company shall notify the Investor by e-mail as promptly as practicable, and in any event, within 24 hours, after the Registration Statement is declared effective or is supplemented and shall provide the Investor with copies of any related prospectus to be used in connection with the sale or other disposition of the securities covered thereby. The Company shall use reasonable best efforts to keep the Initial Registration Statement continuously effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investor of all of the Registrable Securities covered thereby at all times until the earliest to occur of the following events: (i) the date on which the Investor shall have resold all the Registrable Securities covered thereby; and (ii) the date on which the Registrable Securities may be resold by the Investor without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information requirement under Rule 144 under the Securities Act or any other rule of similar effect (the “Registration Period”).

(c)             In the event the number of shares available under the Initial Registration Statement at any time is insufficient to cover the Registrable Securities, the Company shall, to the extent necessary and permissible, amend the Initial Registration Statement or file a new registration statement (together with any prospectuses or prospectus supplements thereunder, a “New Registration Statement”), so as to cover all of such Registrable Securities as soon as reasonably practicable, but in any event not later than ten Business Days after the necessity therefor arises (the “New Registration Filing Deadline”). The Company shall use its reasonable best efforts to have such amendment and/or New Registration Statement become effective as soon as reasonably practicable following the filing thereof but no later than the earlier of the 75th calendar day following the initial filing date of the New Registration Statement if the Commission notifies the Company that it will “review” the New Registration Statement and (b) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the New Registration Statement will not be “reviewed” or will not be subject to further review (the earlier of such dates, the “New Registration Effectiveness Deadline”). The provisions of Section 2(a) and (b) shall apply to the New Registration Statement, except as modified hereby.

4

(d)            On no more than two occasions and for not more than 45 consecutive days or for a total of not more than 90 days in any 12 month period, the Company may delay the effectiveness of the Initial Registration Statement or any other Registration Statement, or suspend the use of any prospectus included in any Registration Statement, in the event that the Company determines in good faith and upon advice of reputable legal counsel that such delay or suspension is necessary to (A) delay the disclosure of material non-public information concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company or (B) amend or supplement the affected Registration Statement or the related prospectus so that such Registration Statement or prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that the Company shall promptly (a) notify each Investor in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor any material non-public information giving rise to an Allowed Delay, (b) advise the Investor in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use reasonable best efforts to terminate an Allowed Delay as promptly as practicable.

(e)             The Investor agrees to furnish to the Company a completed Selling Stockholder Questionnaire and, if reasonably requested by the Company, all other information as shall be reasonably required in connection with the registration of the Registrable Securities. The Investor acknowledges and agrees that the information in the Selling Stockholder Questionnaire or request for further information as described in this Section 2(e) will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement.

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

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

9

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

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

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

10

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

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

6.              Miscellaneous.

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

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

11

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

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

(e)            Assignment. The Company shall not assign this Agreement or any rights or obligations hereunder (whether by operation of law or otherwise) without the prior written consent of the Investor; provided, however, that in any transaction, whether by merger, reorganization, restructuring, consolidation, financing or otherwise, whereby the Company is a party and in which the Registrable Securities are converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Registrable Securities” shall be deemed to include the securities received by the Investor in connection with such transaction unless such securities are otherwise freely tradable by the Investor after giving effect to such transaction, and the prior written consent of the Investor shall not be required for such transaction. The Investor may transfer or assign its rights hereunder, in whole or from time to time in part, to one or more Persons in connection with the transfer of not fewer than 100,000 Registrable Securities by the Investor to such Person, provided that such Investor complies with all laws applicable thereto, and the provisions of the Subscription Agreement, and provides written notice of assignment to the Company promptly after such assignment is effected, and such Person agrees in writing to be bound by all of the provisions contained herein.

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

(g)            Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of the Investor. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. Neither the Company nor the Investor may assign its rights (except by merger or in connection with another entity acquiring all or substantially all of the Company’s assets) or obligations hereunder without the prior written consent of the other party hereto.

12

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

(i)              Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of New York for contracts to be wholly performed in such state and without giving effect to the principles thereof regarding the conflict of laws.

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

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

(l)              Non-Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, the Company covenants, agrees and acknowledges that no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement shall be had against any current or future director, officer, employee, shareholder, general or limited partner or member of the Investor or of any affiliates or assignees thereof, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any current or future director, officer, employee, shareholder, general or limited partner or member of the Investor or of any affiliates or assignees thereof, as such for any obligation of the Investor under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.

13

(m)            Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. Any references to paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary.

Exhibit A

Plan of Distribution

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

·distributions to members, partners, stockholders or other equityholders of the selling stockholders;

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

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

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

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

·privately negotiated transactions;

·short sales and settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

·through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

·broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

·a combination of any such methods of sale; and

A-1

·any other method permitted pursuant to applicable law.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling stockholders for purposes of this prospectus.

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or another available exemption from the registration requirements under the Securities Act.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act (it being understood that the selling stockholders shall not be deemed to be underwriters solely as a result of their participation in this offering). Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

A-2

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling stockholders to use reasonable best efforts to cause the registration statement of which this prospectus constitutes a part to become effective and to remain continuously effective until the earlier of: (i) the date on which the selling stockholders shall have resold or otherwise disposed of all the shares covered by this prospectus and (ii) the date on which the shares covered by this prospectus no longer constitute “Registrable Securities” as such term is defined in the Registration Rights Agreement, such that they may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations and without current public information pursuant to Rule 144 under the Securities Act or any other rule of similar effect.

Each Investor further represents and warrants to the Placement Agents that it, including any fund or funds that it manages or advises that participates in the offer and sale of the Shares, is permitted under its constitutive documents (including, without limitation, all limited partnership agreements, charters, bylaws, limited liability company agreements, all applicable side letters with investors, and similar documents) to make investments of the type contemplated by this Agreement. This Section 8.10 shall survive any termination of this Agreement.

 

(b)          The Company agrees and acknowledges that the Placement Agents may rely on its representations, warranties, agreements and covenants contained in this Agreement and each Investor agrees that the Placement Agents may rely on such Investor’s representations and warranties contained in this Agreement as if such representations and warranties, as applicable, were made directly to the Placement Agents.

 

(c)           Neither the Placement Agents nor any of their respective Affiliates or representatives (1) shall be liable for any improper payment made in accordance with the information provided by the Company; (2) makes any representation or warranty, or has any responsibilities as to the validity, enforceability, accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to the Transaction Agreements or in connection with any of the transactions contemplated therein; or (3) shall be liable (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred upon it by the Transaction Agreements or (y) for anything which any of them may do or refrain from doing in connection with the Transaction Agreements, except in each case for such party’s own gross negligence or willful misconduct.

 

33

 

 

(d)          The Company agrees that the Placement Agents, their respective affiliates and their respective representatives shall be entitled to (1) rely on, and shall be protected in acting upon, any certificate, instrument, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as the Placement Agents hereunder pursuant to the indemnification provisions set forth in the applicable letter agreement between the Company and the Placement Agents.

 

8.11         Third Parties. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties to this Agreement any rights, remedies, claims, benefits, obligations or liabilities under or by reason of this Agreement, and no Person that is not a party to this Agreement (including, without limitation, any partner, member, shareholder, director, officer, employee or other beneficial owner of any party to this Agreement, in its own capacity as such or in bringing a derivative action on behalf of a party to this Agreement) shall have any standing as a third party beneficiary with respect to this Agreement or the transactions contemplated hereby.

8.12         Independent Nature of Investors’ Obligations and Right. The obligations of each Investor under this Agreement are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance obligations of any other Investor under this Agreement. Nothing contained herein, and no action taken by any Investor pursuant hereto, shall be deemed to constitute the Investors as, and the Company acknowledges that the Investors do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group, and the Company will not assert any such claim with respect to such obligations or the transactions contemplated by this Agreement. The Company acknowledges and each Investor confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Investor also acknowledges that Ropes & Gray LLP has not rendered legal advice to such Investor. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company has elected to provide all Investors with the same terms and Transaction Agreements for the convenience of the Company and not because it was required or requested to do so by any Investor.

8.14         Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile or pdf signature including any electronic signatures complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile or pdf (or other electronic reproduction of a) signature.

 

8.15         Entire Agreement; Amendments. This Agreement and the other Transaction Agreements (including all schedules and exhibits hereto and thereto), together with any side letter agreements with any of the Investors, constitute the entire agreement between the parties hereto respecting the subject matter of this Agreement and supersedes all prior agreements, negotiations, understandings, representations and statements respecting the subject matter of this Agreement, whether written or oral. No amendment, modification, alteration, or change in any of the terms of this Agreement shall be valid or binding upon the parties hereto unless made in writing and duly executed by the Company and the Investors of at least a majority in interest of the Shares then held by the Investors, provided that prior to the Closing the consent of all Investors shall be required Notwithstanding the foregoing, this Agreement may not be amended and the observance of any term of this Agreement may not be waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. The Company, on the one hand, and each Investor, on the other hand, may by an instrument signed in writing by such parties waive the performance, compliance or satisfaction by such Investor or the Company, respectively, with any term or provision of this Agreement or any condition hereto to be performed, complied with or satisfied by such Investor or the Company, respectively. Notwithstanding the foregoing or anything else herein to the contrary, no amendment, modification, alteration, change or waiver of this Section 8.15 shall be valid without the prior written consent of the Placement Agents, which consent may be granted or withheld in the sole discretion of the Placement Agents.

 

8.16         Survival. The covenants, representations and warranties made by each party hereto contained in this Agreement shall survive the Closing and the delivery of the Shares in accordance with their respective terms. Each Investor shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

 

8.17         Contract Interpretation. This Agreement is the joint product of each Investor and the Company and each provision of this Agreement has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.

Exhibit 10.4

 

FORM OF REGISTRATION RIGHTS AGREEMENT

 

THIS REGISTRATION RIGHTS AGREEMENT (this “Agreement”), dated as of October 7, 2025, is entered into by and among Zenas BioPharma, Inc., a Delaware corporation (the “Company”), and the several investors signatory hereto (individually as an “Investor” and collectively together with their respective permitted assigns, the “Investors”). Capitalized terms used herein and not otherwise defined herein shall have the respective meanings set forth in the Securities Purchase Agreement by and among the parties hereto, dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”).

 

WHEREAS:

 

A.            Upon the terms and subject to the conditions of the Purchase Agreement, the Company has agreed to issue to the Investors, and the Investors have agreed to purchase, severally and not jointly, an aggregate of up to $119,995,907.30 of shares (the “Shares”) of the Company's common stock, par value $0.0001 per share (the “Common Stock”) pursuant to the Purchase Agreement.

 

B.            To induce the Investors to enter into the Purchase Agreement, the Company has agreed to provide certain registration rights under the U.S. Securities Act of 1933, as amended, and the rules and regulations thereunder, or any similar successor statute (collectively, the “Securities Act”), and applicable state securities laws.

 

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Investors hereby agree as follows:

 

1.DEFINITIONS.

 

For purposes of this Agreement, the following terms shall have the following meanings:

 

(a)            “Person” means an individual, partnership, corporation, limited liability company, business trust, joint stock company, trust, unincorporated association, joint venture or any other entity or organization.

 

(b)            “Prospectus” means (i) the prospectus included in any Registration Statement, as amended or supplemented by any prospectus supplement, with respect to the terms of the offering of any portion of the Registrable Securities covered by such Registration Statement and by all other amendments and supplements to the prospectus, including post-effective amendments and all material incorporated by reference in such prospectus, and (ii) any “free writing prospectus” as defined in Rule 405 under the Securities Act, relating to the terms of the offering of any portion of the Registrable Securities.

 

(c)            “Register,” “Registered,” and “Registration” refer to a registration effected by preparing and filing one or more registration statements of the Company in compliance with the Securities Act and providing for offering securities on a continuous basis, and the declaration or ordering of effectiveness of such registration statement(s) by the U.S. Securities and Exchange Commission (the “SEC”).

 

(d)            “Registrable Securities” means the Shares and any Common Stock issued or issuable with respect to the Shares as a result of any stock split or subdivision, stock dividend, recapitalization, exchange or similar event. Registrable Securities shall cease to be Registrable Securities with respect to each Investor upon the earlier of (i) the date on which such Investor shall have resold all the Registrable Securities held by such Investor covered by the Registration Statement and (ii) the date on which the Registrable Securities may be sold by such Investor under Rule 144(b)(1)(i) of the Securities Act in any ninety (90) day period without volume or manner of sale limitations.

 

 

 

 

(e)            “Registration Expenses” means all registration and filing fee expenses incurred by the Company in effecting any registration pursuant to this Agreement, including (i) all registration, qualification, and filing fees, printing expenses, and any other fees and expenses associated with filings required to be made with the SEC, FINRA or any other regulatory authority, (ii) all fees and expenses in connection with compliance with or clearing the Registrable Securities for sale under any securities or “Blue Sky” laws, (iii) all printing, duplicating, word processing, messenger, telephone, facsimile and delivery expenses, and (iv) all fees and disbursements of counsel for the Company and of all independent certified public accountants of the Company (including the expenses of any special audit and cold comfort letters required by or incident to such performance).

 

(f)            “Registration Statement” means any registration statement of the Company filed with, or to be filed with, the SEC under the Securities Act, that Registers Registrable Securities, including the related Prospectus, amendments and supplements to such registration statement, including pre- and post-effective amendments, and all exhibits and all material incorporated by reference in such registration statement as may be necessary to comply with applicable securities laws. “Registration Statement” shall also include a New Registration Statement, as amended when each became effective, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus subsequently filed with the SEC.

 

(g)            “Required Investors” means the Investors holding a majority of the Registrable Securities outstanding from time to time.

 

(h)            “Selling Expenses” means all underwriting discounts and selling commissions applicable to the sale of Registrable Securities and all similar fees and commissions relating to the Investors’ disposition of the Registrable Securities.

 

2.REGISTRATION.

 

(a)            Mandatory Registration. The Company shall, as promptly as reasonably practicable and in any event no later than 15 days after the Closing Date (the “Filing Deadline”), prepare and file with the SEC an initial Registration Statement (the “Initial Registration Statement”) covering the resale of all Registrable Securities. The Initial Registration Statement shall be designated by the Company as an “automatic shelf registration statement” (as defined in Rule 405 of the Securities Act) if the Company is a “well-known seasoned issuer” (as defined in Rule 405 of the Securities Act) at the time of filing of the Initial Registration Statement with the SEC. Before filing the Registration Statement, the Company shall furnish to the Investors a copy of the Registration Statement. The Investors and their counsel shall have at least three Business Days prior to the anticipated filing date of a Registration Statement to review and comment upon such Registration Statement and any amendment or supplement to such Registration Statement and any related Prospectus, prior to its filing with the SEC. Subject to any SEC comments, such Registration Statement shall include the plan of distribution substantially in the form attached hereto as Exhibit A. Such Registration Statement also shall cover, to the extent allowable under the Securities Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. Such Registration Statement shall not include any shares of Common Stock or other securities for the account of any other holder of securities of the Company without the prior written consent of the Required Investors. The Company shall (a) use commercially reasonable efforts to address in each such document prior to being so filed with the SEC such comments as the Investor or its counsel reasonably proposed by the Investor, and (b) not file any Registration Statement or Prospectus or any amendment or supplement thereto containing information regarding the Investor to which Investor reasonably objects, unless such information is required to comply with any applicable law or regulation. The Investors shall furnish all information reasonably requested by the Company and as shall be reasonably required in connection with any registration referred to in this Agreement.

 

2

 

 

(b)            Effectiveness. The Company shall use its reasonable best efforts to have the Initial Registration Statement and any amendment declared effective by the SEC at the earliest possible date but no later than the earlier of the 75th calendar day following the initial filing date of the Initial Registration Statement if the SEC notifies the Company that it will “review” the Initial Registration Statement and (b) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Initial Registration Statement will not be “reviewed” or will not be subject to further review (the “Effectiveness Deadline”). The Company shall notify the Investor by e-mail as promptly as practicable, and in any event, within 24 hours, after the Initial Registration Statement is declared effective or is supplemented and shall provide the Investor with copies of any Prospectus to be used in connection with the sale or other disposition of the securities covered thereby. The Company shall use reasonable best efforts to keep the Initial Registration Statement continuously effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investors of all of the Registrable Securities covered thereby at all times until the earlier to occur of the following events: (i) the date on which the Investors shall have resold all the Registrable Securities covered thereby; and (ii) the date on which the Registrable Securities may be resold by the Investors without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information requirement under Rule 144 under the Securities Act or any other rule of similar effect (the “Registration Period”). The Initial Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any 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 light of the circumstances in which they were made, not misleading.

 

(c)            Sufficient Number of Shares Registered. In the event the number of shares available under the Initial Registration Statement at any time is insufficient to cover the Registrable Securities, the Company shall, to the extent necessary and permissible, amend the Initial Registration Statement or file a new registration statement (together with any prospectuses or prospectus supplements thereunder, a “New Registration Statement”), so as to cover all of such Registrable Securities as soon as reasonably practicable, but in any event not later than ten Business Days after the necessity therefor arises (the “New Registration Filing Deadline”). The Company shall use its reasonable best efforts to have such amendment and/or New Registration Statement become effective as soon as reasonably practicable following the filing thereof but no later than the earlier of the 75th calendar day following the initial filing date of the New Registration Statement if the SEC notifies the Company that it will “review” the New Registration Statement and (b) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the New Registration Statement will not be “reviewed” or will not be subject to further review (the earlier of such dates, the “New Registration Effectiveness Deadline”). The provisions of Section 2(a) and (b) shall apply to the New Registration Statement, except as modified hereby.

 

(d)            Allowable Delays. On no more than two occasions and for not more than 30 consecutive days or for a total of not more than 60 days in any 12 month period, the Company may delay the effectiveness of the Initial Registration Statement or any other Registration Statement, or suspend the use of any Prospectus, in the event that the Company or Board of Directors determines, in good faith and upon advice of legal counsel, that such delay or suspension is necessary to (A) delay the disclosure of material non-public information concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company or (B) amend or supplement the affected Registration Statement or the related Prospectus so that such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that the Company shall promptly (a) notify each Investor in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor any material non-public information giving rise to an Allowed Delay, (b) advise the Investors in writing to cease all sales under the applicable Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.

 

3

 

 

(e)            Rule 415; Cutback. If at any time the SEC takes the position that the offering of some or all of the Registrable Securities in any Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act (provided, however, the Company shall be obligated to use reasonable best efforts to advocate with the SEC for the registration of all of the Registrable Securities) or requires any Investor to be named as an “underwriter,” the Company shall (i) promptly notify each holder of Registrable Securities thereof and (ii) make commercially reasonable efforts to persuade the SEC that the offering contemplated by such Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Investors is an “underwriter.” The Investors shall have the right to select one legal counsel, which counsel shall be selected by the Required Investors (provided that an Investor may elect to be represented by its own legal counsel at such Investor’s own expense), to review and oversee any registration or matters pursuant to this Section 2(f), including participation in any meetings or discussions with the SEC regarding the SEC’s position and to comment on any written submission made to the SEC with respect thereto. No such written submission with respect to this matter shall be made to the SEC to which any Investor’s counsel reasonably objects. In the event that, despite the Company’s reasonable best efforts and compliance with the terms of this Section 2(f), the SEC refuses to alter its position, the Company shall (i) remove from such Registration Statement such portion of the Registrable Securities (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not name any Investor as an “underwriter” in such Registration Statement without the prior written consent of such Investor (provided that, in the event an Investor withholds such consent, the Company shall have no obligation hereunder to include any Registrable Securities of such Investor in any Registration Statement covering the resale thereof until such time as the SEC no longer requires such Investor to be named as an “underwriter” in such Registration Statement or such Investor otherwise consents in writing to being so named). Any cut-back imposed on the Investors pursuant to this Section 2(f) shall be allocated among the Investors on a pro rata basis and shall be applied first to any of the Registrable Securities of such Investor as such Investor shall designate, unless the SEC Restrictions otherwise require or provide or the Investors otherwise agree.

 

3.RELATED COMPANY OBLIGATIONS.

 

With respect to the Registration Statement and whenever any Registrable Securities are to be Registered pursuant to Section 2, including on the Initial Registration Statement or on any New Registration Statement, the Company shall use its reasonable best efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations:

 

(a)            Notifications. The Company will promptly notify the Investors of the time when any subsequent amendment to the Initial Registration Statement or any New Registration Statement, other than documents incorporated by reference, has been filed with the SEC and/or has become effective or where a receipt has been issued therefor or any subsequent supplement to a Prospectus has been filed and of any request by the SEC for any amendment or supplement to the Registration Statement, any New Registration Statement or any Prospectus or for additional information.

 

4

 

 

(b)            Amendments. The Company will prepare and file with the SEC any amendments, post-effective amendments or supplements to the Initial Registration Statement, any New Registration Statement or any Prospectus, as applicable, that, (a) as may be necessary to keep such Registration Statement effective for the Registration Period and to comply with the provisions of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”) with respect to the distribution of all of the Registrable Securities covered thereby, or (b) in the reasonable opinion of the Investors and the Company, as may be necessary or advisable in connection with any acquisition or sale of Registrable Securities by the Investors.

 

(c)            Investor Review. The Company will not file any amendment or supplement to the Registration Statement, any New Registration Statement or any Prospectus, other than documents incorporated by reference, relating to the Investors, the Registrable Securities or the transactions contemplated hereby unless (A) the Investors and their counsel shall have been advised and afforded the opportunity to review and comment thereon at least three (3) Business Days prior to filing with the SEC and (B) the Company shall have given reasonable due consideration to any comments thereon received from the Investors or their counsel.

 

(d)            Copies Available. The Company will furnish to any Investor whose Registrable Securities are included in any Registration Statement and its counsel copies of the Initial Registration Statement, any Prospectus thereunder (including all documents incorporated by reference therein), any Prospectus supplement thereunder, any New Registration Statement and all amendments to the Initial Registration Statement or any New Registration Statement that are filed with the SEC during the Registration Period (including all documents filed with or furnished to the SEC during such period that are deemed to be incorporated by reference therein), each letter written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion thereof which contains information for which the Company has sought confidential treatment) and such other documents as Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by Investor that are covered by such Registration Statement, in each case as soon as reasonably practicable upon such Investor’s request and in such quantities as such Investor may from time to time reasonably request; provided, however, that the Company shall not be required to furnish any document to the Investor to the extent such document is available on EDGAR.

 

(e)            Notification of Stop Orders; Material Changes. The Company shall use commercially reasonable efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order as soon as practicable. The Company shall advise the Investors promptly (but in no event later than 24 hours) and shall confirm such advice in writing, in each case: (i) of the Company’s receipt of notice of any request by the SEC or any other federal or state governmental authority for amendment of or a supplement to the Registration Statement or any Prospectus or for any additional information; (ii) of the Company’s receipt of notice of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Initial Registration Statement or prohibiting or suspending the use of any Prospectus or Prospectus supplement, or any New Registration Statement, or of the Company’s receipt of any notification of the suspension of qualification of the Registrable Securities 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 any Registration Statement or any Prospectus untrue or which requires the making of any additions to or changes to the statements then made in any Registration Statement or any 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 any Prospectus, in light of the circumstances under which they were made) not misleading, or of the necessity to amend any Registration Statement or any Prospectus to comply with the Securities Act or any other law. The Company shall not be required to disclose to the Investors the substance of specific reasons of any of the events set forth in clause (i) to (iii) of the immediately preceding sentence (each, a “Suspension Event”), but rather, shall only be required to disclose that the event has occurred. If at any time the SEC, or any other federal or state governmental authority shall issue any stop order suspending the effectiveness of any Registration Statement or prohibiting or suspending the use of any Prospectus or Prospectus supplement, the Company shall use its reasonable best efforts to obtain the withdrawal of such order at the earliest practicable time. The Company shall furnish to the Investors, without charge, a copy of any correspondence from the SEC or the staff of the SEC, or any other federal or state governmental authority to the Company or its representatives relating to the Initial Registration Statement, any New Registration Statement or any Prospectus, or Prospectus supplement as the case may be. In the event of a Suspension Event set forth in clause (iii) of the first sentence of this Section 3(e), the Company will use its commercially reasonable efforts to publicly disclose such event as soon as reasonably practicable, or otherwise resolve the matter such that sales under Registration Statements may resume; provided, however, that if the Company has a bona fide business purpose for not making such information public, the Company may suspend the use of all Registration Statements for up to 60 consecutive calendar days; provided, further, that the Company may not suspend the use of all Registration Statements more than twice, or for more than 90 total calendar days, in each case during any twelve-month period.

 

5

 

 

(f)            Confirmation of Effectiveness. If reasonably requested by an Investor at any time in respect of any Registration Statement, the Company shall deliver to such Investor a written confirmation (email being sufficient) from Company’s counsel of whether or not the effectiveness of such Registration Statement has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not such Registration Statement is currently effective and available to the Company for sale of Registrable Securities.

(h)            Compliance. The Company shall otherwise use best efforts to comply with all applicable rules and regulations of the SEC under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under the Securities Act, promptly inform the Investor in writing if, at any time during the Registration Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Investor is required to deliver a prospectus in connection with any disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder, and make available to its security holders, as soon as reasonably practicable, but not later than the Availability Date (as defined below), an earnings statement covering a period of at least 12 months, beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act, including Rule 158 promulgated thereunder (for the purpose of this subsection 3(h), “Availability Date” means the 45th day following the end of the fourth fiscal quarter that includes the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the 90th day after the end of such fourth fiscal quarter).

 

(i)            Blue-Sky. The Company shall register or qualify or cooperate with the Investor and their counsel in connection with the registration or qualification of such Registrable Securities for the offer and sale under the securities or blue sky laws of such jurisdictions reasonably requested by the Investor; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (i) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(i), (ii) subject itself to general taxation in any jurisdiction where it would not otherwise be so subject but for this Section 3(i), or (iii) file a general consent to service of process in any such jurisdiction.

(j)            Rule 144. With a view to making available to the Investors the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock to the public without registration, the Company covenants and agrees to: (i) make and keep adequate current public information available, as those terms are understood and defined in Rule 144, until the earlier of (A) six months after such date as all of the Registrable Securities may be sold without restriction by the holders thereof pursuant to Rule 144 or any other rule of similar effect or (B) such date as there are no longer Registrable Securities; and (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Exchange Act; (iii) furnish electronically to each Investor upon request, as long as such Investor owns any Registrable Securities, (A) a written statement by the Company that it has complied with the reporting requirements of the Exchange Act, (B) a copy of or electronic access to the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be reasonably requested in order to avail such Investor of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration.

4.OBLIGATIONS OF THE INVESTORS.

 

(a)            Investor Information. Each Investor shall provide a completed Investor Questionnaire in the form attached hereto as Exhibit B or such other form or information required by the Company in connection with the registration of the Registrable Securities. If the Company has not received such completed Questionnaire from an Investor within three Business Days of the Company’s request, the Company may file the Registration Statement without including such Investor’s Registrable Securities.

 

(b)            Suspension of Sales. Each Investor, severally and not jointly with any other Investor, agrees that, upon receipt of any notice from the Company of the existence of an Allowed Delay or a Suspension Event as set forth in Section 3(e), the Investor will promptly discontinue disposition of Registrable Securities pursuant to any Registration Statement covering such Registrable Securities until the Investor's receipt of a notice from the Company confirming the resolution of such Allowed Delay or Suspension Event and that such dispositions may again be made; provided, for the avoidance of doubt, that the foregoing shall not limit the right of the Investor to sell or otherwise dispose of the Registrable Securities pursuant to Rule 144 or any other exemption from the registration requirements of the Securities Act or to settle a transaction pursuant to a Registration Statement as to which a contract for such sale was entered into prior to such Investor’s receipt of the notice from the Company of the existence of the Allowed Delay or Suspension Event. The Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of an Investor in accordance with any sale of Registrable Securities pursuant to a Registration Statement with respect to which such Investor has entered into a contract for sale prior to such Investor’s receipt of the notice from the Company of the existence of the Allowed Delay or Suspension Event.

 

7

 

 

(c)            Investor Cooperation. Each Investor, severally and not jointly with any other Investor, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any amendments and supplements to any Registration Statement or New Registration Statement hereunder, unless such Investor has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement.

(a)            To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Investors, each Person, if any, who controls the Investors, the members, the directors, officers, partners, employees, members, managers, agents, representatives and advisors of the Investors and each Person, if any, who controls the Investors within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Person”), against any losses, obligation, claims, damages, liabilities, contingencies, judgments, fines, penalties, charges, costs (including, without limitation, court costs and costs of preparation), reasonable and documented attorneys’ fees, amounts paid in settlement or reasonable and documented expenses, (collectively, “Claims”) reasonably incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency or body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement or omission or alleged omission of any material fact contained in any Registration Statement, any preliminary prospectus or final prospectus, or any amendment or supplement thereof, or (ii) any violation or alleged violation by the Company or any of its Subsidiaries of the Securities Act, Exchange Act or any other state securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered or any rule or regulation promulgated thereunder applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration of the Registrable Securities (the matters in the foregoing clauses (i) and (ii) being, collectively, “Violations”). The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any reasonable out-of-pocket legal fees or other reasonable and documented expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (A) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by the Investors or such Indemnified Person specifically for use in such Registration Statement or prospectus and was reviewed and approved in writing by such Investor or such Indemnified Person expressly for use in connection with the preparation of any Registration Statement, any prospectus or any such amendment thereof or supplement thereto, if such in each case if the foregoing was timely made available by the Company; (B) with respect to any superseded prospectus, shall not inure to the benefit of any such Person from whom the Person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any other Indemnified Person) if the untrue statement or omission of material fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, and the Indemnified Person was promptly advised in writing not to use the outdated, defective or incorrect prospectus prior to the use giving rise to a Violation; (C) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 8.

(b)            In connection with the Initial Registration Statement, any New Registration Statement or any Prospectus, the Investors, severally and not jointly, agree to indemnify, hold harmless and defend, the Company, each of its directors, each of its officers who signed the Initial Registration Statement or signs any New Registration Statement, each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Party”), against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with information about an Investor furnished in writing by such Investor to the Company and reviewed and approved in writing by such Investor or such Indemnified Person expressly for use in connection with the preparation of the Registration Statement, any New Registration Statement, any prospectus or any such amendment thereof or supplement thereto. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 6 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in such Registration Statement giving rise to such indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by any Investor pursuant to Section 8.

 

(c)            Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be, and upon such notice, the indemnifying party shall not be liable to the Indemnified Person or the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Person or the Indemnified Party in connection with the defense thereof; provided, however, that an Indemnified Person or Indemnified Party (together with all other Indemnified Persons and Indemnified Parties that may be represented without conflict by one counsel) shall have the right to retain its own counsel with the reasonable fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise unless such judgment or settlement (i) imposes no liability or obligation on, (ii) includes as an unconditional term thereof the giving of a complete, explicit and unconditional release from the party bringing such indemnified claims of all liability of the Indemnified Party or Indemnified Person in respect to or arising out of such claim or litigation in favor of, and (iii) does not include any admission of fault, culpability, wrongdoing, or wrongdoing or malfeasance by or on behalf of, the Indemnified Party or Indemnified Person. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

 

9

 

 

(d)            The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred. Any Person receiving a payment pursuant to this Section 6 which person is later determined to not be entitled to such payment shall return such payment (including reimbursement of expenses) to the person making it.

 

(e)            The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

 

7.CONTRIBUTION.

 

To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 7 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by such seller from the sale of such Registrable Securities giving rise to such contribution obligation.

 

8.ASSIGNMENT OF REGISTRATION RIGHTS.

 

The Company shall not assign this Agreement or any rights or obligations hereunder (whether by operation of law or otherwise) without the prior written consent of the Required Investors; provided, however, that in any transaction, whether by merger, reorganization, restructuring, consolidation, financing or otherwise, whereby the Company is a party and in which the Registrable Securities are converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Registrable Securities” shall be deemed to include the securities received by the Investor in connection with such transaction unless such securities are otherwise freely tradable by the Investor after giving effect to such transaction, and the prior written consent of the Required Investors shall not be required for such transaction.

 

10

 

 

An Investor may transfer or assign its rights hereunder, in whole or from time to time in part, to one or more Persons in connection with the transfer of Registrable Securities (including Registrable Securities issuable upon exercise of Warrants) by such Investor to such Person, provided that such Investor complies with all laws applicable thereto, and the provisions of the Purchase Agreement, and provides written notice of assignment to the Company promptly after such assignment is effected, and such Person agrees in writing to be bound by all of the provisions contained herein.

 

The provisions of this Agreement shall be binding upon and inure to the benefit of the Investor and its successors and permitted assigns.

 

9.AMENDMENTS AND WAIVERS.

 

The provisions of this Agreement, including the provisions of this sentence, may be amended, modified or supplemented, or waived only by a written instrument executed by (i) the Company and (ii) the Required Investors, provided that (1) any party may give a waiver as to itself, (2) any amendment, modification, supplement or waiver that disproportionately and adversely affects the rights and obligations of any Investor relative to the comparable rights and obligations of the other Investors shall require the prior written consent of such adversely affected Investor or each Investor, as applicable, and (3) any amendments to Section 6 or to the definitions of “Filing Deadline,” “Effectiveness Deadline,” or “Registration Period” shall require the written consent of each Investor. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of one or more Investors and that does not adversely directly or indirectly affect the rights of other Investors may be given by Investors holding all of the Registrable Securities to which such waiver or consent relates.

Exhibit A

 

PLAN OF DISTRIBUTION

 

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

 

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

 

distributions to members, partners, stockholders or other equityholders of the selling stockholders;

 

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

 

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

 

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

 

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

 

privately negotiated transactions;

 

short sales and settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

 

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

 

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

 

a combination of any such methods of sale; and

 

any other method permitted pursuant to applicable law.

 

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling stockholders for purposes of this prospectus.

 

1

 

 

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

 

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

 

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or another available exemption from the registration requirements under the Securities Act.

 

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act (it being understood that the selling stockholders shall not be deemed to be underwriters solely as a result of their participation in this offering). Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

 

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

 

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

 

2

 

 

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

 

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

 

We have agreed with the selling stockholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part to become effective and to remain continuously effective until the earlier of: (i) the date on which the selling stockholders shall have resold or otherwise disposed of all the shares covered by this prospectus and (ii) the date on which the shares covered by this prospectus no longer constitute “Registrable Securities” as such term is defined in the Registration Rights Agreement, such that they may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations and without current public information pursuant to Rule 144 under the Securities Act or any other rule of similar effect.

WALTHAM, Mass. and Beijing, October 8, 2025 (GLOBE NEWSWIRE) – Zenas BioPharma, Inc. (“Zenas,” “Zenas BioPharma” or the “Company”) (Nasdaq: ZBIO) and InnoCare Pharma Limited (“InnoCare” or “InnoCare Pharma”) (HKEX: 09969; SSE: 688428) today announced a transformational license agreement granting Zenas global development and commercialization rights to orelabrutinib for Multiple Sclerosis (MS) and across all therapeutic areas other than oncology. Zenas also secured rights to a novel, oral, IL-17AA/AF inhibitor, and an oral, brain-penetrant, TYK2 inhibitor.

 

Orelabrutinib is a potentially best-in-class, highly selective CNS-penetrant, oral, small molecule BTK inhibitor with the potential to address compartmentalized inflammation and disease progression in MS. A global, Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical trial evaluating the safety and efficacy of orelabrutinib dosed 80 mg once daily (QD) in patients with Primary Progressive MS (PPMS) has been initiated. Zenas plans to initiate a second global, Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical trial evaluating orelabrutinib in patients with Secondary Progressive MS (SPMS) in the first quarter of 2026.

 

In a previously completed global Phase 2 clinical trial in patients with Relapsing-Remitting MS (RRMS), orelabrutinib demonstrated significant reductions in new Gd+ T1 lesions versus placebo at weeks 12 and 24, with sustained reductions in inflammatory activity through week 96 as demonstrated by meaningful impact on endpoints indicative of disease progression. The safety and tolerability profile of orelabrutinib is consistent with other BTK inhibitors in development for MS and is well characterized across multiple prior autoimmune disease and hematologic cancer trials.

 

 

 

 

 

“InnoCare is a globally recognized company with a successful track record of drug discovery, development and commercialization. This transformative collaboration with InnoCare further positions Zenas to execute on its vision to become a global, fully integrated development and commercial-stage autoimmune-focused biopharmaceutical company. With global rights to orelabrutinib, we are advancing a potential blockbuster franchise for progressive MS. Orelabrutinib, with its best-in-class potential, is strongly positioned to address disease progression independent of relapse activity, the highest unmet medical need in MS, and to improve the lives of patients living with progressive MS. We are also excited to add two potentially best-in-class molecules, a novel, oral, IL-17AA/AF inhibitor and an oral, brain-penetrant, TYK2 inhibitor, to our pipeline. We plan to advance each of these programs to human clinical trials in 2026 and expect to have initial patient data from the oral IL-17AA/AF clinical program in 2027,” said Lonnie Moulder, Founder and Chief Executive Officer (CEO) of Zenas.

 

“We are delighted to partner with Zenas BioPharma. The partnership with Zenas BioPharma represents a significant milestone in our journey, and we will continue to enhance and advance our globalization efforts in the future,” said Dr. Jasmine Cui, Co-Founder, Chairwoman and CEO of InnoCare Pharma. “Orelabrutinib has a differentiated mechanism of action and strong clinical data underscoring its promising potential as a treatment for patients with progressive forms of MS. We are confident in Zenas’ management team given their exceptional track record of successful drug development, global regulatory approvals and commercial launches, and their commitment to driving innovation for autoimmune diseases.”

 

Mr. Moulder continued, “With this transaction, we have established a balanced portfolio of complementary mechanisms and modalities with best-in-class blockbuster potential across multiple therapeutic areas. With our two franchise programs, obexelimab concluding Phase 3 development for IgG4-RD, and now orelabrutinib for progressive forms of MS, Zenas is well positioned to meaningfully impact the lives of patients living with autoimmune diseases. We are prioritizing the tremendous opportunity ahead with orelabrutinib in PPMS and SPMS. We expect to report obexelimab topline 12-week primary endpoint results from the Phase 2 MoonStone trial in patients with RMS early in the fourth quarter of 2025 and 24-week data in the first quarter of 2026. We anticipate making a program decision based on these data and the evolving landscape for the development of new therapies for RMS in early 2026.”

 

“This strategic collaboration will leverage our shared focus to accelerate the development of orelabrutinib and help maximize its clinical and commercial potential on a global scale, particularly in MS,” added Dr. Cui, “Given the statistically significant and clinically meaningful data from the Phase 2 trial, and promising blood-brain barrier penetration capability, orelabrutinib has the potential to transform the treatment paradigm for this devastating disease. In addition to orelabrutinib, we have fortified our powerful discovery engine to focus on cutting-edge targets for the development of autoimmune therapeutics through B-cell and T-cell pathways, with the aim of delivering first-in-class and/or best-in-class treatments to address the massive unmet medical needs and strong market potential in China and worldwide.”

 

“BTK inhibition is a validated mechanism for the treatment of progressive forms of MS, and there is immense scientific interest in its potential to impact inflammation compartmentalized in the CNS and thereby potentially impact disability progression independent of relapse activity. We believe the differentiated, potentially best-in-class profile of orelabrutinib could make a meaningful difference for patients with PPMS and SPMS, which have few treatment options. With our late-stage development capabilities and expertise in MS, we are well positioned to execute on the pivotal, global, Phase 3 development of orelabrutinib, as well as advance two early candidates into clinical development,” said Lisa von Moltke, M.D., Head of Research and Development and Chief Medical Officer of Zenas.

About Obexelimab
Obexelimab is a bifunctional monoclonal antibody designed to bind both CD19 and FcγRIIb, which are broadly present across B cell lineage, to inhibit the activity of cells that are implicated in many autoimmune diseases without depleting them. This unique mechanism of action and self-administered, subcutaneous injection regimen may broadly and effectively address the pathogenic role of the B cell lineage in chronic autoimmune disease.

 

Obexelimab has been evaluated in six clinical trials in a total of 208 patients who received obexelimab either as an intravenous infusion or as a subcutaneous injection. Obexelimab was well tolerated and demonstrated clinical activity across these clinical trials, providing the Company with an initial clinical proof of concept for obexelimab as a potent B cell inhibitor for the treatment of patients living with certain autoimmune diseases. Zenas is conducting a fully enrolled Phase 3 trial in Immunoglobulin G4-Related Disease and Phase 2 trials for Relapsing Multiple Sclerosis and Systemic Lupus Erythematosus.

Obexelimab Recent Developments

 

Our Global Phase 2 Trial in RMS – MoonStone

 

In the second quarter of 2025, we completed enrollment of our Phase 2, double-blind, randomized, placebo controlled trial (the “MoonStone” trial) for obexelimab as a treatment for relapsing multiple sclerosis (“RMS”) and expect to report results from the MoonStone trial, including the 12-week primary endpoint results, early in the fourth quarter of 2025. The MoonStone trial, which remains blinded, enrolled 116 patients, with baseline characteristics including: a mean age of 42, 81 (70%) female, a median Expanded Disability Status Scale (“EDSS”) score of 3, and 25 patients with GdE T1 hyperintense lesions at screening, including a mean of .71 GdE T1 hyperintense lesions. Preliminary blinded review of MoonStone’s randomized controlled data (obexelimab and placebo 2:1 randomized) up to week 12 showed a rapid decline in new GdE T1 hyperintense lesions from .71 to .09 and new and existing lesions from .71 to .18. These are preliminary observations from an ongoing blinded study and are subject to change upon final unblinding and analysis.

 

In early 2026, we expect to decide whether and how to advance obexelimab for RMS based on a variety of factors, including our analysis of MoonStone trial data, including the 12 and 24-week data, the evolving landscape for the development of new therapies for RMS, including available therapies and regulatory endpoints, and allocation of capital.

 

Our Global Phase 2 Trial in SLE – SunStone

 

We expect to complete enrollment in our Phase 2, double-blind, randomized, placebo controlled trial (the “SunStone” trial) for obexelimab as a treatment for Systemic Lupus Erythematosus (“SLE”) around year-end 2025, and we expect to report topline results from the SunStone trial in mid-2026. Based on the outcome of the SunStone trial, and considering other factors, we may initiate a Phase 3 program in patients with SLE in the first half of 2027.

 

Our Global Phase 3 Trial in IgG4-RD – INDIGO

 

In the fourth quarter of 2024, we completed the target enrollment of our registration-directed Phase 3 trial (the “INDIGO” trial) for obexelimab as a treatment for IgG4-RD, and we expect to report topline results from the INDIGO trial around year-end 2025. If the topline results are positive, we expect to file a Biologics License Application with the U.S. Food and Drug Administration (“FDA”) in the first half of 2026, followed by a Marketing Authorization Application with the European Medicines Agency, and, if approved, commence the commercial launch initially in the U.S. and then in Europe.

 

Orelabrutinib Overview

 

Orelabrutinib, also known as ZB020, is a highly selective and central nervous system (“CNS”)-penetrant, oral small molecule BTK inhibitor. Orelabrutinib is designed to bind irreversibly to BTK with minimal off-target effects, compared to certain other BTK inhibitors, which may potentially reduce certain side effects. We believe orelabrutinib is designed to efficiently cross the blood-brain barrier, reaching therapeutic levels within the CNS to directly target inflammation in diseases like MS. This CNS penetration may be important for addressing the underlying disease pathology of progressive forms of MS, which is characterized by compartmentalized neuroinflammation and neurodegeneration. The mechanism of action of BTK inhibitors targets not only pathogenic B cells in the periphery, but also those in the CNS, as well as macrophages and microglial cells addressing the key pathogenic drivers of progressive MS, as shown below.

 

 

 

 

 

 

Orelabrutinib for the Treatment of MS

 

A significant unmet need exists in MS for CNS-penetrant mechanisms that address compartmentalized local inflammation and directly impact the biology of progressive disease and neurodegeneration. BTK inhibition could potentially address the underlying biology of progressive disease by impacting peripherally and centrally located pathogenic B cells and macrophages, and directly inhibiting microglia in the CNS.

 

We estimate a diagnosed prevalence of over 125,000 patients with secondary progressive multiple sclerosis (“SPMS”) and approximately 60,000 to 100,000 patients with primary progressive multiple sclerosis (“PPMS”) in the U.S. SPMS and PPMS have the highest unmet need across MS subtypes, with limited therapeutic options. Currently no treatments are approved for non-relapsing/non-active SPMS and only one approved treatment, Ocrevus, for PPMS. We estimate that the commercial opportunity for MS could exceed $30 billion, with in excess of $12 billion attributable to progressive forms of MS.

 

 

 

 

Phase 2 Study in RMS

 

In late 2024, the results of the Phase 2 trial of orelabrutinib for the treatment of RMS were announced. The Phase 2 trial was a global, double-blind, placebo-controlled trial. The primary endpoint was the cumulative number of new gadolinium-enhancing (“Gd+”) T1 brain lesions at Week 12 (based on new Gd+ T1 lesions at Weeks 4, 8, and 12) compared to placebo. The results of the Phase 2 trial demonstrated that treatment with orelabrutinib resulted in a rapid and deep reduction in new Gd+ T1 lesions across all evaluated doses. In the trial, 158 eligible RRMS patients were randomized in a 1:1:1:1 ratio to one of four treatment groups: placebo, orelabrutinib 50 mg once daily (“QD”), orelabrutinib 80 mg QD, and orelabrutinib 50 mg twice daily (“BID”). Subjects in the placebo group were switched to orelabrutinib 50 mg QD at Week 13.

 

 

 

At Week 12, all three treatment groups showed statistically significant reductions in the cumulative number of new Gd+ T1 lesions and new/enlarging T2 lesions compared to the placebo group (p < 0.05), while the 80 mg QD and 50 mg BID groups showed statistically significant reductions throughout 24 weeks compared to the placebo/50 mg QD group (p < 0.05). The 80 mg QD group demonstrated the highest reductions of 90.4% at Week 12 compared to placebo and 92.3% at Week 24 compared to the placebo/50 mg QD group. New lesion control in each orelabrutinib group occurred at the earliest assessment timepoint of Week 4 and was sustained through Week 24.

 

Safety Summary

 

Orelabrutinib was generally well tolerated in the Phase 2 study of patients with RMS.  

 

The known potential risks of orelabrutinib, as observed in clinical trials in patients with B-cell malignancies and autoimmune disease, include those associated with BTK inhibitor treatment such as hepatotoxicity, hemorrhage, cytopenia, infection, malignancy, hypertension, and arrhythmia.

 

 

 

 

In the Phase 2 RRMS trial, 151 patients received at least one dose of orelabrutinib. Treatment emergent adverse events(“TEAEs”) leading to drug discontinuation occurred in 2.6% of patients. The majority of TEAEs were Grades 1 or 2. Observed Grade 3 or higher events primarily included hematologic toxicities and infections, which are mechanism-related and commonly reported with BTK inhibitor treatment.

 

Elevation of liver enzyme levels classified as hepatotoxicity were observed in the Phase 2 RMS trial (ICP-CL-00112), as well as in Phase 1/2 trials in patients with SLE (ICP-CL-00109 and ICP-CL-00124) and Phase 2/3 trials in patients with Immune Thrombocytopenia (ICP-CL-00116 and ICP-CL-00126). Two cases of elevated liver enzymes and bilirubin met Hy’s Law criteria, one in the Phase 2 RMS trial and the other in the SLE trial. Both affected patients were asymptomatic and their liver markers normalized after treatment was discontinued. FDA issued a partial clinical hold for the conduct of the ongoing RMS trial. Three other BTK inhibitors, including those currently in development for progressive MS, were also placed on a partial clinical hold while under development in the U.S. for RMS. No development restrictions were placed by the European Medicines Agency.  In the Phase 3 progressive MS trials, weekly liver function monitoring will be conducted during the first 12 weeks of treatment, which will be implemented through an established hepatotoxicity management scheme. In addition, the safety of the study, including hepatotoxicity, will be monitored by an Independent Data Monitoring Committee (IDMC) and a Hepatoxicity Assessment Committee (HAC) through periodic or ad hoc reviews of study safety observations.

 

Orelabrutinib has been approved for commercial use for chronic lymphocytic leukemia and small lymphocytic lymphoma in China since December 2020.

 

Phase 3 Studies for PPMS and SPMS

 

In September 2024, InnoCare and the FDA reached an agreement to initiate a Phase 3 trial of orelabrutinib in patients with PPMS. The FDA also encouraged InnoCare to initiate a second Phase 3 clinical trial of orelabrutinib in Progressive Multiple Sclerosis (“PMS”) within the Secondary Progressive Multiple Sclerosis (“SPMS”) population. In February 2025, InnoCare reached alignment with the FDA on the Phase 3 clinical trial protocol for SPMS.

 

In September 2025, the Phase 3 study of orelabrutinib in patients with PPMS was initiated. The Phase 3 study is a global, multicenter, randomized, double-blind, placebo-controlled clinical trial evaluating the safety and efficacy of orelabrutinib dosed 80 mg once daily QD compared to placebo in patients with PPMS, with a primary endpoint of time to onset of 12-week composite confirmed disability progression (cCDP), with a goal to report topline results in 2030.

 

 

 

 

 

 

In the first quarter of 2026, we plan to initiate a second global, Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical trial evaluating orelabrutinib dosed 80 mg QD compared to placebo in patients with SPMS, with a primary endpoint of time to onset of 24-week CDP, with a goal to report topline results in 2030.

 

 

 

Early-Development Product Candidates: ZB021 and ZB022

 

We also in-licensed from InnoCare certain exclusive rights to two early-development product candidates: ZB021, an oral IL-17AA/AF inhibitor designed to block both IL-17AA homodimer and IL-17AF heterodimer signaling, and ZB022, an oral, brain-penetrant TYK2-JH2 inhibitor.

 

We believe ZB021 provides an opportunity for Zenas to expand its pipeline within rheumatology and into other therapeutic areas including dermatology. Anti-IL-17 biologics are a drug class focused on the treatment of rheumatic and dermatologic diseases that we estimate currently represents an approximately $10 billion commercial opportunity, with an average of approximately 50% annual growth since the first approval of a product was obtained. Preclinical studies for ZB021 have shown favorable PK and ADME properties. ZB021 achieved comparable activity in vivo to a reference anti-IL-17 biologic in a rat CIA model. Subject to the results of Investigational New Drug (“IND”)-enabling studies, Zenas expects to submit an IND application for ZB021, and if cleared, initiate a Phase 1 clinical study in 2026, with the potential for initial data in 2027.

 

ZB022 is currently in IND-enabling studies. Subject to the results of IND-enabling studies, Zenas expects to submit an IND application for ZB022, and if cleared, initiate a Phase 1 clinical study in 2026, with the potential for initial data in 2027.
