Company shall use its commercially reasonable efforts at the first opportunity that is permitted by the Commission to register for resale the Reduction Securities (pro rata among the Holders of such Reduction Securities) using one or more registration statements that it is then entitled to use. The Company shall use its commercially reasonable efforts to cause each such registration statement to be declared effective under the Securities Act as soon as possible, and shall use its commercially reasonable efforts to keep such registration statement continuously effective under the Securities Act during the entire Effectiveness Period. Notwithstanding the foregoing, the Company shall be entitled to suspend the effectiveness of such Registration Statement at any time prior to the expiration of the Effectiveness Period for the reasons and time periods during a Blackout Period. No liquidated damages shall accrue or be payable to any Holder pursuant to Section 3(b) with respect to any Registrable Securities that are excluded by reason of the Staff limiting the number of Registrable Securities that may be sold pursuant to a registration statement; provided that the Company continues to use commercially reasonable efforts to register such Registrable Securities for resale by other available means. Notwithstanding anything herein to the contrary, if the Commission limits the Company’s ability to file, or prohibits or delays the filing of a new registration statement, the Company’s compliance with such limitation, prohibition or delay solely to the extent of such limitation, prohibition or delay shall not be deemed a failure by the Company to use commercially reasonable efforts as set forth above or elsewhere in this Agreement and shall not require the payment of any liquidated damages by the Company under this Agreement.

(b)    Liquidated Damages. If a Registration Event occurs, then the Company will make payments to each Holder of Registrable Securities, as liquidated damages to such Holder by reason of the Registration Event, a cash sum calculated at a rate of twelve percent (12%) per annum of the total of the following, to the extent applicable to such Holder: (i) if the Holder purchased Registrable Securities pursuant to the Subscription Agreement, the aggregate purchase price paid by such Holder pursuant to the Subscription Agreement, (ii) if the Holder is a Placement Agent or a designee of a Placement Agent, $3.00 upon exercise of Placement Agent Warrants (or in the case of unexercised Placement Agent Warrants, of the exercise price thereof), or (iii) if the Holder is a Holder of Merger Shares or Registrable Pre-Merger Shares, the product of $3.00 (as adjusted for stock splits, stock dividends, combinations, recapitalizations or similar events) multiplied by the number of Merger Shares or Registrable Pre-Merger Shares held by such Holder, but in each case of (i)-(iii), only with respect to such Holder’s Registrable Securities that are affected by such Registration Event and only for the period during which such Registration Event continues to affect such Registrable Securities. Notwithstanding the foregoing, the maximum amount of liquidated damages that may be paid by the Company pursuant to this Section 3(b) shall be an amount equal to five percent (5%) of the applicable foregoing amounts described in clauses (i), (ii) and (iii) in the preceding sentence with respect to such Holder’s Registrable Securities that are affected by all Registration Events in the aggregate. Each payment of liquidated damages pursuant to this Section 3(b) shall be due and payable in arrears within five (5) days after the end of each full 30-day period of the Registration Default Period until the termination of the Registration Default Period and within five (5) days after such termination. The Registration Default Period shall terminate upon the earlier of such time as the Registrable Securities that are affected by the Registration Event cease to be Registrable Securities or (i) the filing of the Registration Statement in the case of clause (a) of the definition of Registration Event, (ii) the SEC Effective Date in the case of clause (b) of the definition of Registration Event, (iii) the ability of the Holders to effect sales pursuant to the Registration

6

Statement in the case of clause (c) of the definition of Registration Event, and (iv) the listing or inclusion and/or trading of the Common Stock on an Approved Market, as the case may be, in the case of clause (d) of the definition of Registration Event. The amounts payable as liquidated damages pursuant to this Section 3(b) shall be payable in lawful money of the United States. Notwithstanding the foregoing, the Company will not be liable for the payment of liquidated damages described in this Section 3(b) for any delay in registration of Registrable Securities that would otherwise be includable in the Registration Statement pursuant to Rule 415 solely as a result of a comment received from the Staff requiring a limit on the number of Registrable Securities included in such Registration Statement in order for such Registration Statement to be able to avail itself of Rule 415, or, with respect to a Holder, if such Holder fails to provide to the Company information concerning the Holder and manner of distribution of the Holder’s Registrable Securities that is required by SEC Rules to be disclosed in a registration statement utilized in connection with the registration of the Registrable Securities. In the event of any such circumstance, the Company will use its commercially reasonable efforts at the first opportunity that is permitted by the Commission to register for resale the Registrable Securities that have been cut back from being registered pursuant to Rule 415 only with respect to that portion of the Holders’ Registrable Securities that are then Registrable Securities.

(c)    Other Limitations. Notwithstanding the provisions of Section 3(b) above, if (i) the Commission does not declare the Registration Statement effective on or before the Registration Effectiveness Date, or (ii) the Commission allows the Registration Statement to be declared effective at any time before or after the Registration Effectiveness Date, subject to the withdrawal of certain Registrable Securities from the Registration Statement, and the reason for (i)    or (ii) is the Commission’s determination that (x) the offering of any of the Registrable Securities constitutes a primary offering of securities by the Company, (y) Rule 415 may not be relied upon for the registration of the resale of any or all of the Registrable Securities, and/or (z) a Holder of any Registrable Securities must be named as an underwriter, the Holders understand and agree that in the case of (ii) the Company may (notwithstanding anything to the contrary contained herein) reduce, on a pro rata basis, in the manner provided above, the total number of Registrable Securities to be registered on behalf of each such Holder, and in the case of (i) or (ii) the Holder shall not be entitled to liquidated damages with respect to the Registrable Securities not registered for the reason set forth in (i) or so reduced on a pro rata basis as set forth in (ii) above. The Company shall use its commercially reasonable efforts at the first opportunity that is permitted by the Commission to register for resale the Reduction Securities (pro rata among the Holders of such Reduction Securities) using one or more registration statements that it is then entitled to use. The Company shall use its commercially reasonable efforts to cause each such registration statement to be declared effective under the Securities Act as soon as possible, and shall use its commercially reasonable efforts to keep such registration statement continuously effective under the Securities Act during the entire Effectiveness Period. No liquidated damages shall accrue or be payable to any Holder pursuant to this Section 3(c) with respect to any Registrable Securities that are excluded by reason of the Staff limiting the number of Registrable Securities that may be sold pursuant to a registration statement; provided that the Company continues to use commercially reasonable efforts to register such Registrable Securities for resale by other available means. Notwithstanding anything herein to the contrary, if the Commission limits the Company’s ability to file, or prohibits or delays the filing of a new registration statement, the Company’s compliance with such limitation, prohibition or delay solely to the extent of such limitation, prohibition or delay shall not be deemed a failure by the Company to use commercially reasonable efforts as set forth above or elsewhere in this Agreement and shall not require the payment of any liquidated damages by the Company under this Agreement.

7

(d)    If the Company receives a written notice from the Holders of at least 50% of the Registrable Securities then outstanding that they desire to distribute the Registrable Securities held by them (or a portion thereof) by means of an underwritten offering or a block trade, the Company shall use commercially reasonable efforts to promptly engage one or more underwriter(s) or investment bank(s) to conduct such an offering of the Registrable Securities (a “Secondary Offering”). The underwriter(s) or investment bank(s) will be selected by the Company and shall be reasonably acceptable to the Holders of a majority of the Registrable Securities providing such notice. All Holders proposing to distribute their securities through such Secondary Offering shall enter into an underwriting agreement or other agreement(s), including any lock-up or market standoff agreements, in customary form with the underwriter(s) or investment bank(s) selected for such Secondary Offering as may be mutually agreed upon among the Company, the underwriter(s) or investment bank(s) and the selling Holders. In connection with a Secondary Offering, the Company shall enter into and perform its obligations under an underwriting agreement or other agreement(s), in usual and customary form as may be mutually agreed upon among the Company, the underwriter(s) or investment bank(s) and the selling Holders. Notwithstanding any other provision of this Section 3(d), if the underwriter(s) or investment bank(s) advise(s) such Holders that marketing factors require a limitation on the number of shares to be offered in the Secondary Offering, then the number of shares, including the Registrable Securities, that may be included in such Secondary Offering shall be allocated among such Holders of Registrable Securities, and any other holders of shares, as follows: (i) first to such Holders of Registrable Securities in proportion (as nearly as practicable) to the number of Registrable Securities owned by each such Holder or in such other proportion as shall mutually be agreed to by all such selling Holders; and (ii) second to all other holders of securities included in the Secondary Offering.

(a)    In the event of the offer and sale of Registrable Securities under the Securities Act, the Company shall, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, partners, employees and agents and each other person, if any, who controls or is under common control with such Holder within the meaning of Section 15 of the Securities Act (collectively, the “Holder Indemnified Parties”), against any losses, claims, damages or liabilities, joint or several, and expenses to which the Holder Indemnified Parties may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement prepared and filed by the Company under which Registrable Securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated or necessary to make the statements therein in light of the circumstances in which they were made not misleading, and the Company shall reimburse the Holder Indemnified Parties for any legal or any other expenses reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage, liability, action or proceeding; provided, however, that the Company shall not be liable in any such case (i) to the extent, but only to the extent, that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises solely out of or is solely based upon (x) an untrue statement in or omission from such registration statement, any such preliminary

12

prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information included in the Selling Securityholder Questionnaire, attached hereto as Annex A, furnished by a Holder or its representative (acting on such Holder’s behalf) to the Company expressly for use in the preparation thereof or (y) the failure of a Holder to comply with the covenants and agreements contained in Section 5 hereof respecting the sale of Registrable Securities; or (ii) if the person asserting any such loss, claim, damage, liability (or action or proceeding in respect thereof) who purchased the Registrable Securities that are the subject thereof did not receive a copy of an amended preliminary prospectus or the final prospectus (or the final prospectus as amended or supplemented) at or prior to the written confirmation of the sale of such Registrable Securities to such person because of the failure of such Holder to so provide such amended preliminary or final prospectus and the untrue statement or omission of a material fact made in such preliminary prospectus was corrected in the amended preliminary or final prospectus (or the final prospectus as amended or supplemented). Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holder Indemnified Parties and shall survive the transfer of such shares by the Holder.

(b)    As a condition to including Registrable Securities in any registration statement filed pursuant to this Agreement, each Holder agrees, severally and not jointly, to be bound by the terms of this Section 8 and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, each of its directors, officers, partners, and each underwriter, if any, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which the Company or any such director or officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise solely out of or are solely based upon any untrue statement of a material fact or any omission of a material fact required to be stated in any registration statement, any preliminary prospectus, final prospectus, summary prospectus, amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue statement or omission is included or omitted in reliance upon and in conformity with written information included in the Selling Securityholder Questionnaire, attached hereto as Annex A, furnished by the Holder or its representative (acting on such Holder’s behalf) to the Company expressly for use in the preparation thereof, and such Holder shall reimburse the Company, and its directors, officers, partners, and any such controlling persons for any legal or other expenses reasonably incurred by them in connection with investigating, defending, or settling any such loss, claim, damage, liability, action, or proceeding; provided, however, that indemnity obligation contained in this Section 8(b) shall in no event exceed the amount of the net proceeds received by such Holder as a result of the sale of such Holder’s Registrable Securities pursuant to such registration statement. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling person and shall survive the transfer by any Holder of such shares.

(c)    Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in this Section 8 (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the indemnifying party of the

13

commencement of such action; provided, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice in any material respect. In case any such action is brought against an indemnified party, unless in the reasonable judgment of counsel to such indemnified party a conflict of interest between such indemnified party and indemnifying parties may exist or the indemnified party may have defenses not available to the indemnifying party in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof or the indemnifying party fails to defend such claim in a diligent manner, other than reasonable costs of investigation. Neither an indemnified party nor an indemnifying party shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement, which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the defense of a claim. Each indemnified party shall furnish such information regarding itself or the claim in question as an indemnifying party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

(d)    If an indemnifying party does not or is not permitted to assume the defense of an action pursuant to Section 8(c) or in the case of the expense reimbursement obligation set forth in Sections 8(a) and 8(b), the indemnification required by Sections 8(a) and 8(b) 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 expenses, losses, damages, or liabilities are incurred.

(e)    If the indemnification provided for in Section 8(a) or 8(b) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense (i) in such proportion as is appropriate to reflect the proportionate relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission), or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, then in such proportion as is appropriate to reflect not only the proportionate relative

14

fault of the indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, as well as any other relevant equitable considerations. Notwithstanding any other provision of this Section 8(e), no Holder shall be required to contribute any amount in excess of the amount by which the net proceeds received by such Holder from the sale of the Registrable Securities pursuant to the Registration Statement exceeds the amount of damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement of a material fact or omission, except in the case of fraud or willful misconduct. No indemnified party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation.

(f)    The indemnity and contribution agreements contained in this Section 8 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.

9.    Rule 144. The Company shall file with the Commission “Form 10 information” (as defined in Rule 144(i)(3) under the Securities Act) reflecting its status as an entity that is no longer an issuer described in Rule 144(i)(1)(i) promptly following the closing of the Merger. Following the Effective Date, the Company will use its commercially reasonable efforts to timely file all reports required to be filed by the Company after the date hereof under the Exchange Act and the rules and regulations adopted by the Commission thereunder, and if the Company is not required to file reports pursuant to such sections, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell shares of Common Stock under Rule 144.

10.    Independent Nature of Each Purchaser’s Obligations and Rights. The obligations of each Purchaser and each Broker under this Agreement are several and not joint with the obligations of any other Purchaser or Broker, and each Purchaser and each Broker shall not be responsible in any way for the performance of the obligations of any other Purchaser or any Broker under this Agreement. Nothing contained herein and no action taken by any Purchaser or Broker pursuant hereto, shall be deemed to constitute such Purchasers and/or Brokers as a partnership, an association, a joint venture, or any other kind of entity, or create a presumption that the Purchasers and/or Brokers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser and each Broker 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 Purchaser or Broker to be joined as an additional party in any proceeding for such purpose.

11.    Miscellaneous.

(a)    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the United States of America and the State of Delaware, both substantive and remedial, without regard to Delaware conflicts of law principles. Any judicial proceeding brought against either of the parties to this Agreement or any dispute arising out of this Agreement or any matter related hereto shall be brought in the state or federal courts located

15

in the State of Delaware and, by its execution and delivery of this Agreement, each party to this Agreement accepts the jurisdiction of such courts. The foregoing consent to jurisdiction shall not be deemed to confer rights on any person other than the parties to this Agreement.

(b)    Remedies. Except as otherwise specifically set forth herein with respect to a Registration Event, in the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement, each Holder 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, shall be entitled to specific performance of its rights under this Agreement. Except as otherwise specifically set forth herein with respect to a Registration Event, the Company and each Holder 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 agrees that, in the event of any action for specific performance in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would be adequate.

(c)    Subsequent Registration Rights. Until the Registration Statement required hereunder is declared effective by the Commission, the Company shall not enter into any agreement granting any registration rights with respect to any of its securities to any Person without the written consent of Holders representing no less than a majority of the outstanding Registrable Securities.

(d)    Successors and Assigns. Except as otherwise provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, Permitted Assignees, executors and administrators of the parties hereto.

(e)    No Inconsistent Agreements. The Company has not entered, as of the date hereof, and shall not enter, on or after the date of this Agreement, into any agreement with respect to its securities that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof.

(f)    Entire Agreement. This Agreement and the documents, instruments and other agreements specifically referred to herein or delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof.

(g)    Notices, etc. All notices, consents, waivers, and other communications which are required or permitted under this Agreement shall be in writing will be deemed given to a party (a) upon receipt, when personally delivered; (b) one (1) Business Day after deposit with an nationally recognized overnight courier service with next day delivery specified, costs prepaid) on the date of delivery, if delivered to the appropriate address by hand or by nationally recognized overnight courier service (costs prepaid); (c) the date of transmission if sent by facsimile or e-mail with confirmation of transmission by the transmitting equipment if such notice or communication is delivered prior to 5:00 P.M., New York City time, on a Trading Day, or the next Trading Day after the date of transmission, if such notice or communication is delivered on a day that is not a Trading Day or later than 5:00 P.M., New York City time, on any Trading Day, provided confirmation of facsimile is mechanically or electronically generated and kept on file by the sending party and confirmation of email is kept on file, whether electronically

MAX-1 ACQUISITION CORPORATION

(TO BE RENAMED EXICURE, INC.)

Selling Securityholder Notice and Questionnaire

The undersigned beneficial owner of Registrable Securities of Max-1 Acquisition Corporation (to be renamed Exicure, Inc.), a Delaware corporation (the “Company”), understands that the Company has filed or intends to file with the U.S. Securities and Exchange Commission a registration statement (the “Registration Statement”) for the registration and resale under Rule 415 of the Securities Act of 1933, as amended, of the Registrable Securities, in accordance with the terms of the Registration Rights Agreement (the “Registration Rights Agreement”) to which this document is annexed. A copy of the Registration Rights Agreement is available from the Company upon request at the address set forth below. All capitalized terms not otherwise defined herein shall have the meanings ascribed thereto in the Registration Rights Agreement.

Certain legal consequences arise from being named as a selling security holder in the Registration Statement and the related prospectus. Accordingly, holders and beneficial owners of Registrable Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a selling security holder in the Registration Statement and the related prospectus.

NOTICE

The undersigned beneficial owner (the “Selling Securityholder”) of Registrable Securities hereby elects to include the Registrable Securities owned by it in the Registration Statement.

The undersigned hereby provides the following information to the Company and represents and warrants that such information is accurate:

4. Beneficial Ownership of Securities of the Company Owned by the Selling Securityholder:

Except as set forth below in this Item 4, the undersigned is not the beneficial or registered owner of any securities of the Company.

5. Relationships with the Company:

Except as set forth below, neither you nor (if you are a natural person) any member of your immediate family, nor (if you are not a natural person) any of your affiliates², officers, directors or principal equity holders (owners of 5% of more of the equity securities of the undersigned) has held any position or office or has had any other material relationship with the Company (or its predecessors or affiliates) during the past three years.

State any exceptions here:

It is possible that a security may have more than one “beneficial owner,” such as a trust, with two co-trustees sharing voting power, and the settlor or another third party having investment power, in which case each of the three would be the “beneficial owner” of the securities in the trust. The power to vote or direct the voting, or to invest or dispose of, or direct the investment or disposition of, a security may be indirect and arise from legal, economic, contractual or other rights, and the determination of beneficial ownership depends upon who ultimately possesses or shares the power to direct the voting or the disposition of the security.

The final determination of the existence of beneficial ownership depends upon the facts of each case. You may, if you believe the facts warrant it, disclaim beneficial ownership of securities that might otherwise be considered “beneficially owned” by you.

The undersigned agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein that may occur subsequent to the date hereof at any time while the Registration Statement remains effective.

By signing below, the undersigned consents to the disclosure of the information contained herein in its answers to Items 1 through 5 and the inclusion of such information in the Registration Statement and the related prospectus and any amendments or supplements thereto. The undersigned understands that such information will be relied upon by the Company in connection with the preparation or amendment of the Registration Statement and the related prospectus and any amendments or supplements thereto.

IN WITNESS WHEREOF the undersigned, by authority duly given, has caused this Selling Securityholder Notice and Questionnaire to be executed and delivered either in person or by its duly authorized agent.
