EXHIBIT 10.1

FORM OF

This Subscription Agreement (this “Agreement”) has been executed by the purchaser set forth on the signature page hereof (the “Purchaser”) in connection with the private placement offering (the “Offering”) by Exicure, Inc., a Delaware corporation (formerly known as Max-1 Acquisition Corporation, the “Company”).

R E C I T A L S

A. The Company is offering a minimum of 6,666,666 shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), at a purchase price of $3.00 per share (the “Purchase Price”), for an aggregate purchase price of approximately $20 million (the “Minimum Offering Amount”), and a maximum of 13,333,333 shares of Common Stock at the Purchase Price for an aggregate Purchase Price of approximately $40 million (the “Maximum Offering Amount”). The Company may also sell an additional 3,333,333 shares of Common Stock at the Purchase Price for an aggregate Purchase Price of approximately $10 million to cover over-subscriptions (the “Over-Subscription Option”), in the event the Offering is oversubscribed.

B. The Initial Closing (as defined below) of no less than the Minimum Offering Amount, including the Minimum Insider Investment (as defined below) has been completed on September 26, 2017 concurrently with the closing of a merger by and among the Company, Max-1 Acquisition Sub, Inc., a Delaware corporation (“Merger-Sub”) and wholly owned subsidiary of the Company, and Exicure Operating Company, a Delaware corporation (formerly known as Exicure, Inc., “Exicure”), pursuant to which Merger-Sub merged with and into Exicure, with Exicure surviving the merger as a wholly owned subsidiary of the Company (the “Merger”) and pursuant to which all of the outstanding shares of Exicure’s capital stock were exchanged for 26,666,627 shares of the Company’s Common Stock (the “Merger Shares”). Upon the consummation of the Merger, Exicure changed its name to “Exicure Operating Company” and the Company changed its name to “Exicure, Inc.”

C. The Shares (as defined below) subscribed for pursuant to this Agreement have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). The Offering is being made on a reasonable best efforts basis to “accredited investors,” as defined in Regulation D under the Securities Act in reliance upon the exemption from securities registration afforded by Section 4(a)(2) of the Securities Act and Rule 506 of Regulation D.

AGREEMENT

The Company and the Purchaser hereby agree as follows:

1. Subscription.

1.1 Purchase and Sale of the Shares.

(a) Subject to the terms and conditions of this Agreement, the undersigned Purchaser agrees to purchase, and the Company agrees to sell and issue to such Purchaser, that number of shares set forth on such Purchaser’s Omnibus Signature Page attached hereto at the Purchase Price, for a total aggregate Purchase Price as set forth on such Omnibus Signature Page. The minimum subscription amount for each Purchaser in the Offering is

$49,998 (or 16,666 shares). The Company may accept subscriptions for less than $49,998 from any Purchaser in its sole discretion. Stockholders of Exicure will purchase a minimum of $12.5 million of Shares in the Offering (the “Minimum Insider Investment”) and certain existing stockholders of the Company will purchase a minimum of $500,000 of Shares in the Offering. For the purposes of this Agreement, “Shares” means the shares of Common Stock issued in the Offering at the Initial Closing (as defined below), the First Subsequent Closing (as defined below) or at any Subsequent Closing (as defined below).

(b) This Agreement is one of a series of subscription agreements issued (and to be issued) by the Company to purchasers of Shares in connection with the Offering with substantially the same terms and conditions set forth in this Agreement (each, a “Subscription Agreement”, and collectively, the “Subscription Agreements”).

1.2 Subscription Procedure; Closing.

(a) Initial Closing. The initial closing of purchase and sale of Shares in the Offering took place on September 26, 2017 (the “Initial Closing”).

(b) First Subsequent Closing. A subsequent closing of the purchase and sale of the Shares shall take place remotely via the exchange of documents and signatures on October 27, 2017 or at such other time and place as mutually agreed to by the Company and the Purchaser (the “First Subsequent Closing”).

(c) Subsequent Closings. If the Maximum Offering Amount is not sold at the Initial Closing or at the First Subsequent Closing, at any time prior to October 31, 2017 or at such later time as the Company and the Placement Agents may mutually agree without notice to or consent from the Purchaser, the Company may sell additional Shares up to the Maximum Offering Amount and if there are over-subscriptions, such additional Shares as may be sold in connection with the Over-Subscription Option to such persons as may be approved by the Company and who are reasonably acceptable to the Placement Agents (the “Additional Purchasers”) (the closing of each sale contemplated by this subsection (c), a “Subsequent Closing”); provided that in no event shall any Subsequent Closing occur after November 30, 2017 (the “Long-Stop Date”). The Company shall timely file with the Securities and Exchange Commission (the “SEC”) a Current Report on Form 8-K relating to the sale of securities in any such Subsequent Closing. All such sales made at any Subsequent Closing, shall be made on the same terms and conditions set forth in this Agreement.

(d) Subscription Procedure. To complete a subscription for the Shares pursuant hereto, the Purchaser must fully comply with the subscription procedure provided in paragraphs i. through iii. of this Section on or before the First Subsequent Closing or any Subsequent Closing, as applicable:

(i) Subscription Documents. At or before the First Subsequent Closing or any Subsequent Closing, as applicable, the Purchaser shall review, complete and execute the Omnibus Signature Page to this Agreement and the Registration Rights Agreement substantially in the form of Exhibit A hereto (the “Registration Rights Agreement”), Investor Profile, Anti-Money Laundering Form and Investor Certification, attached hereto following the Omnibus Signature Page (collectively, the “Subscription Documents”), if applicable, additional forms and questionnaires distributed to the Purchaser and deliver the Subscription Documents and such additional forms and questionnaires to the party indicated thereon at the address set forth under the caption “How to subscribe for Shares in the private offering of the Company.” below. Executed documents may be delivered to such party by facsimile or .pdf sent by electronic mail (e-mail).

(ii) Purchase Price. Simultaneously with the delivery of the Subscription Documents as provided herein, and in any event at or prior to the First Subsequent Closing or any Subsequent Closing, as applicable, the Purchaser shall deliver to Delaware Trust Company, in its capacity as escrow agent (the “Escrow Agent”), under an escrow agreement among the Company, the Placement Agents (as defined below) and the Escrow Agent (the “Escrow Agreement”) the full Purchase Price set forth on the Purchaser’s Omnibus Signature Page attached hereto, by certified or other bank check or by wire transfer of immediately available funds, pursuant to the instructions set forth under the caption “How to subscribe for Shares in the private offering of the Company” below. Such funds will be held for the Purchaser’s benefit in the escrow account established for the Offering (the “Escrow Account”) and will be returned promptly upon the Purchaser’s written request to the Escrow Agent or the Company, without interest or offset, if this Agreement is not accepted by the Company or if the Offering is terminated pursuant to the terms herein prior to the First Subsequent Closing or any Subsequent Closing, as applicable.

(iii) Company Discretion. The Purchaser understands and agrees that the Company in its sole discretion reserves the right to accept or reject this or any other subscription for Shares, in whole or in part, notwithstanding prior receipt by the Purchaser of notice of acceptance of this subscription. The Company shall have no obligation hereunder until the Company shall execute and deliver to the Purchaser an executed copy of this Agreement. If this subscription is rejected by the Company in whole pursuant to the first sentence of this Section 1.2(d)(iii), or the Offering is terminated, the Company shall immediately return, and shall cause the Escrow Agent to immediately return, all funds paid by or on behalf of the Purchaser pursuant to this Agreement, without interest or offset, and this Agreement shall thereafter be of no further force or effect. If this subscription is rejected by the Company in part, the Company shall immediately return, and shall cause the Escrow Agent to immediately return, all funds paid by or on behalf of the Purchaser for the rejected portion of this subscription, without interest or offset, and this Agreement shall continue in full force and effect to the extent this subscription was accepted.

2. Placement Agents.

(a) Katalyst Securities LLC., a U.S.-registered broker-dealer (“Katalyst”), has been engaged by the Company as placement agent on a reasonable best efforts basis, for the Offering. The Company, subject to its agreement with Katalyst, or Katalyst itself, may engage additional placement agents (Katalyst together with any such additional placement agents, the “Placement Agents”).

(b) The aggregate cash commission paid and Placement Agent Warrant (as defined below) coverage issued to the Placement Agents in connection with the Initial Closing is disclosed in the Super 8-K.

(c) The Placement Agents, collectively, will be paid at the First Subsequent Closing and each Subsequent Closing from the Offering proceeds a total cash commission of seven percent (7%) of the gross Purchase Price paid by Purchasers in the First Subsequent Closing and the applicable Subsequent Closings (if any) introduced by them (the “Cash Fee”) and will collectively receive warrants to purchase a number of shares of Common Stock equal to 7% of the number of shares of Common Stock sold to investors at

the First Subsequent Closing and the applicable Subsequent Closings (if any), introduced by them, with a term of three (3) years from the date of First Subsequent Closing and the applicable Subsequent Closing, and at an exercise price of $3.00 per share (the “Placement Agent Warrants”); provided that with respect to funds raised in the First Subsequent Closing and the applicable Subsequent Closings (if any) from existing stockholders of Exicure or other purchasers as agreed to by Exicure and Katalyst, the Company will, at the Company’s discretion, either (a) pay to the Placement Agents a cash payment equal to 6% of the aggregate amount raised from existing stockholders of Exicure in the Initial Closing, the First Subsequent Closing or any Subsequent Closing, as applicable or (b) issue to the Placement Agents a number of shares of the Company’s Common Stock equal to the quotient of (i) 6% of the aggregate amount raised from existing stockholders of Exicure in the Initial Closing, the First Subsequent Closing or any applicable Subsequent Closings, divided by (ii) the Purchase Price with respect to the Initial Closing, the First Subsequent Closing or any Subsequent Closings, as applicable, or (c) any combination of clauses (a) and (b) (the “Insider Payment”). Funds raised from existing stockholders of Exicure in the First Subsequent Closing and the applicable Subsequent Closings will have no Placement Agent Warrant coverage.

(d) As a condition to payment of the Insider Payment, Katalyst must raise a minimum of $10,000,000 in the Offering prior to October 31, 2017 (the “Finance Contingency”) from investors who are not existing Exicure investors. The Company has agreed that if Katalyst raises less than $10,000,000 in the Offering (and therefore the Finance Contingency is not met), but Katalyst raises more than $7,000,000 in the Offering, the Company will pay an amount of the Insider Payment at the First Subsequent Closing and each of the Subsequent Closings, as applicable, equal to the product of (a) 75% multiplied by (b) the quotient of (i) the amount raised by Katalyst in the Initial Closing, the First Subsequent Closing or any Subsequent Closing, as applicable, divided by (ii) $10,000,000, multiplied by (c) the Insider Payment that would be due at the Initial Closing, the First Subsequent Closing or any applicable Subsequent Closing, as the case may be, in the absence of the Finance Contingency. For the avoidance of doubt, the description of the Placement Agent compensation set forth in Section 2(c) and Section 2(d) is intended to be consistent with the description set forth in the Super 8-K (as defined below) and does not enlarge or create any obligation on the part of the Company that would not otherwise exist.

(e) The Company will also pay certain expenses of the Placement Agents in connection with the Offering. Any sub-agent of the Placement Agent that introduces investors that participate in the First Subsequent Closing and the applicable Subsequent Closings of the Offering will be entitled to share in the Cash Fee, Insider Payment and/or Placement Agent Warrants attributable to those investors pursuant to the terms of an executed sub-agent agreement. The shares, if any, issued pursuant to the Insider Payment will be subject to a lock-up agreement for a period of 18 months.

3. Representations and Warranties of the Company. Except (i) as set forth in the Disclosure Schedule delivered to the Purchaser concurrently with the execution of this Agreement (the “Disclosure Schedule”), or (ii) as disclosed in the Form 8-K describing the Merger, the Offering and the related transactions filed by the Company with the SEC on October 2, 2017 (the “Super 8-K”) (but excluding any disclosures contained under the heading “Risk Factors” and any disclosure of risks included in any “forward-looking statements” disclaimer or in any other section to the extent they are forward-looking statements or cautionary, predictive or forward-looking in nature), or (iii) as disclosed in the

The Company and each of its subsidiaries is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the assets, business, financial condition, results of operations or future prospects of the Company and its subsidiaries taken as a whole (a “Material Adverse Effect”). Each subsidiary of the Company is identified on Schedule 3a attached hereto.

(b) Authorization, Enforcement, Compliance with Other Instruments.

(e) No Conflicts. The execution, delivery and performance of each of the Transaction Documents by the Company, and the consummation by the Company of the transactions contemplated hereby and thereby including issuance and sale of the Shares in accordance with this Agreement will not (i) result in a violation of the Certificate of Incorporation or the Bylaws (or equivalent constitutive document) of the Company or any of its subsidiaries or (ii) violate or conflict with, or result in a breach of any provision of, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any subsidiary is a party, except for those which would not reasonably be expected to have a Material Adverse Effect, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including U.S. federal and state securities laws and regulations) applicable to the Company or any subsidiary or by which any property or asset of the Company or any subsidiary is bound or affected, except for those which would not reasonably be expected to have a Material Adverse Effect. Neither the Company nor any subsidiary is in violation of or in default under, any provision of its Certificate of Incorporation or Bylaws. Neither the Company nor any subsidiary is in violation of any term of or in default under any contract, agreement, mortgage, indebtedness, indenture, instrument, judgment, decree or order or any statute, rule or regulation applicable to the Company or any subsidiary, which violation or breach has had or would reasonably be expected to have a

Material Adverse Effect. Except as specifically contemplated by this Agreement and as required under the Securities Act and any applicable state securities laws, neither the Company nor any of its subsidiaries is required to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its obligations under or contemplated by this Agreement or the other Transaction Documents in accordance with the terms hereof or thereof. Except as disclosed in Schedule 3(e) or the Super 8-K, neither the execution and delivery by the Company of the Transaction Documents, nor the consummation by the Company of the transactions contemplated hereby or thereby, will require any notice, consent or waiver under any contract or instrument to which the Company or any subsidiary is a party or by which the Company or any subsidiary is bound or to which any of their assets is subject, except for any notice, consent or waiver the absence of which would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect. All consents, authorizations, orders, filings and registrations which the Company or any of its subsidiaries is required to obtain pursuant to the preceding two sentences have been or will be obtained or effected on or prior to the First Subsequent Closing.

(f) Absence of Litigation. Except as disclosed in Schedule 3(f) or the Super 8-K, there is no action, suit, claim, inquiry, notice of violation, proceeding (including any partial proceeding such as a deposition) or investigation before or by any court, public board, governmental or administrative agency, self-regulatory organization, arbitrator, regulatory authority, stock market, stock exchange or trading facility (an “Action”) now pending or, to the knowledge of the Company, threatened against or affecting the Company or any of its subsidiaries or any of their respective officers or directors, which would be reasonably likely to (i) adversely affect the validity or enforceability of, or the authority or ability of the Company to perform its obligations under, this Agreement or any of the other Transaction Documents, or (ii) have a Material Adverse Effect. For the purpose of this Agreement, the knowledge of the Company means the knowledge of the officers of the Company (for the avoidance of doubt, after giving effect to the Merger) and Exicure (both actual or constructive knowledge that they would have had upon reasonable inquiry of the personnel of Exicure responsible for the applicable subject matter). Neither the Company nor any of its subsidiaries is subject to any judgment, decree, or order which has had, or would reasonably be expected to have a Material Adverse Effect.

such terms are used in and construed under Rule 144 under the Securities Act (“Rule 144”). With respect to a Purchaser, any investment fund or managed account that is managed on a discretionary basis by the same investment manager as such Purchaser will be deemed to be an Affiliate of such Purchaser.

(i) No Integrated Offering. Neither the Company, nor any of its Affiliates, nor to the knowledge of the Company, any person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of the Shares under the Securities Act or cause this offering of the Shares to be integrated with prior offerings by the Company for purposes of the Securities Act.

(j) Employee Relations. Neither Company nor any subsidiary is involved in any labor dispute nor, to the knowledge of the Company, is any such dispute threatened. Neither Company nor any subsidiary is party to any collective bargaining agreement. The Company’s and/or its subsidiaries’ employees are not members of any union, and the Company believes that its and its subsidiaries’ relationship with their respective employees is good.

(a) The Purchaser has the knowledge and experience in financial and business matters necessary to evaluate the merits and risks of its prospective investment in the Company, and has carefully reviewed and understands the risks of, and other considerations relating to, the purchase of Shares and the tax consequences of the investment, and has the ability to bear the economic risks of the investment. The Purchaser can afford the loss of his, her or its entire investment.

(b) The Purchaser is acquiring the Shares for investment for his, her or its own account and not with the view to, or for resale in connection with, any distribution thereof. The Purchaser understands and acknowledges that the Offering and sale of the Shares have not been registered under the Securities Act or any state securities laws, by reason of a specific exemption from the registration provisions of the Securities Act and applicable state securities laws, which depends upon, among other things, the bona fide nature of the investment intent as expressed herein. The Purchaser further represents that he, she or it does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participation to any third person with respect to any of the Shares. The Purchaser understands and acknowledges that the Offering of the Shares will not be registered under the Securities Act nor under the state securities laws on the ground that the sale of the Shares to the Purchaser as provided for in this Agreement and the issuance of securities hereunder is exempt from the registration requirements of the Securities Act and any applicable state securities laws. The Purchaser is an “accredited investor” as defined in Rule 501 of Regulation D as promulgated by the SEC under the Securities Act, for the reason(s) specified on the Accredited Investor Certification attached hereto as completed by Purchaser, and Purchaser shall submit to the Company such further assurances of such status as may be reasonably requested by the Company.

The Purchaser has not taken any of the actions set forth in, and is not subject to, the disqualification provisions of Rule 506(d)(1) of the Securities Act.

(c) The Purchaser (i) if a natural person, represents that he or she is the greater of (A) 21 years of age or (B) the age of legal majority in his or her jurisdiction of residence, and has full power and authority to execute and deliver this Agreement and all other related agreements or certificates and to carry out the provisions hereof and thereof; (ii) if a corporation, partnership, limited liability company, association, joint stock company, trust, unincorporated organization or other entity, represents that such entity was not formed for the specific purpose of acquiring the Shares, such entity is duly organized, validly existing and in good standing under the laws of the state or jurisdiction of its organization, the consummation of the transactions contemplated hereby is authorized by, and will not result in a violation of state law or its charter or other organizational documents, such entity has full power and authority to execute and deliver this Agreement and all other related agreements or certificates and to carry out the provisions hereof and thereof and to purchase and hold the Shares, the execution and delivery of this Agreement has been duly authorized by all necessary action, this Agreement has been duly executed and delivered on behalf of such entity and is a legal, valid and binding obligation of such entity; or (iii) if executing this Agreement in a representative or fiduciary capacity, represents that he, she or it has full power and authority to execute and deliver this Agreement in such capacity and on behalf of the subscribing individual, xxxx, partnership, trust, estate, corporation, or limited liability company or partnership, or other entity for whom the Purchaser is executing this Agreement, and such individual, partnership, xxxx, trust, estate, corporation, or limited liability company or partnership, or other entity has full right and power to perform pursuant to this Agreement and make an investment in the Company, and represents that this Agreement constitutes a legal, valid and binding obligation of such entity. The execution and delivery of this Agreement will not violate or be in conflict with any order, judgment, injunction, agreement or controlling document to which the Purchaser is a party or by which it is bound.

(d) The Purchaser understands that the Shares are being offered and sold to him, her or it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Purchaser’s compliance with, the representations,

warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire such securities. The Purchaser further acknowledges and understands that the Company is relying on the representations and warranties made by the Purchaser hereunder and that such representations and warranties are a material inducement to the Company to sell the Shares to the Purchaser. The Purchaser further acknowledges that without such representations and warranties of the Purchaser made hereunder, the Company would not enter into this Agreement with the Purchaser.

(e) The Purchase understands that, other than as expressly provided in the Registration Rights Agreement, the Company does not currently intend to register the Shares under the Securities Act at any time in the future; and the undersigned will not immediately be entitled to the benefits of Rule 144 with respect to the Shares. The Purchaser understands that no public market exists for the Company’s Common Stock and that there can be no assurance that any public market for the Common Stock will exist or continue to exist. The Company’s Common Stock is not approved for quotation on OTC Markets or any other quotation system or listed on any exchange. The Company intends to cause the Common Stock to be quoted on OTC Markets QB tier as soon as practicable following the final Subsequent Closing of the Offering; however, the Company makes no representation, warranty or covenant with respect to the initiation of or continued quotation of the Common Stock on the OTC Markets quotation or listing on any other market or exchange.

(f) The Purchaser has received, reviewed and understood the information about the Company, including all Disclosure Materials, and has had an opportunity to discuss the Company’s business, management and financial affairs with the Company’s management. The Purchaser understands that such discussions, as well as any Disclosure Materials provided by the Company, were intended to describe the aspects of the Company’s business and prospects and the Offering which the Company believes to be material, but were not necessarily a thorough or exhaustive description, and except as expressly set forth in this Agreement, the Company makes no representation or warranty with respect to the completeness of such information and makes no representation or warranty of any kind with respect to any information provided by any entity other than the Company. Some of such information may include projections as to the future performance of the Company, which projections may not be realized, may be based on assumptions which may not be correct and may be subject to numerous factors beyond the Company’s control. The Purchaser acknowledges that he, she or it is not relying upon any person or entity, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. Additionally, the Purchaser understands and represents that he, she or it is purchasing the Shares notwithstanding the fact that the Company may disclose in the future certain material information the Purchaser has not received, including (without limitation) financial statements of the Company for the current or prior fiscal periods, and any subsequent period financial statements that will be filed with the SEC. Each Purchaser has sought such accounting, legal and tax advice as the Purchaser has considered necessary to make an informed investment decision with respect to his, her or its acquisition of the Shares.

(g) The Purchaser acknowledges that none of the Company or the Placement Agents is acting as a financial advisor or fiduciary of the Purchaser (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and no investment advice has been given by the Company, the Placement Agents or any of their respective representatives or agents in connection with

the Transaction Documents and the transactions contemplated hereby and thereby. The Purchaser further represents to the Company that the Purchaser’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Purchaser and the Purchaser’s representatives.

(h) As of the First Subsequent Closing or any Subsequent Closing, as applicable, all actions on the part of Purchaser, and its officers, directors and partners, if applicable, necessary for the authorization, execution and delivery of this Agreement and the Registration Rights Agreement and the performance of all obligations of the Purchaser hereunder and thereunder shall have been taken, and this Agreement and the Registration Rights Agreement, assuming due execution by the parties hereto and thereto, constitute valid and legally binding obligations of the Purchaser, enforceable in accordance with their respective terms, subject to: (i) judicial principles limiting the availability of specific performance, injunctive relief, and other equitable remedies and (ii) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect generally relating to or affecting creditors’ rights.

(i) Purchaser represents that neither it nor, to its knowledge, any person or entity controlling, controlled by or under common control with it, nor any person having a beneficial interest in the Purchaser, nor any person on whose behalf the Purchaser is acting: (i) is a person listed in the Annex to Executive Order No. 13224 (2001) issued by the President of the United States (Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism); (ii) is named on the List of Specially Designated Nationals and Blocked Persons maintained by the U.S. Office of Foreign Assets Control; (iii) is a non-U.S. shell bank or is providing banking services indirectly to a non-U.S. shell bank; (iv) is a senior non-U.S. political figure or an immediate family member or close associate of such figure; or (v) is otherwise prohibited from investing in the Company pursuant to applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules or orders (categories (i) through (v), each a “Prohibited Purchaser”). The Purchaser agrees to provide the Company, promptly upon request, all information that the Company reasonably deems necessary or appropriate to comply with applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules and orders. The Purchaser consents to the disclosure to U.S. regulators and law enforcement authorities by the Company and its Affiliates and agents of such information about the Purchaser as the Company reasonably deems necessary or appropriate to comply with applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules and orders. If the Purchaser is a financial institution that is subject to the USA Patriot Act, the Purchaser represents that it has met all of its obligations under the USA Patriot Act. The Purchaser acknowledges that if, following its investment in the Company, the Company reasonably believes that the Purchaser is a Prohibited Purchaser or is otherwise engaged in suspicious activity or refuses to promptly provide information that the Company requests, the Company has the right or may be obligated to prohibit additional investments, segregate the assets constituting the investment in accordance with applicable regulations or immediately require the Purchaser to transfer the Shares. The Purchaser further acknowledges that neither the Purchaser nor any of the Purchaser’s Affiliates or agents will have any claim against the Company or Exicure for any form of damages as a result of any of the foregoing actions.

(j) If the Purchaser is Affiliated with a non-U.S. banking institution (a “Foreign Bank”), or if the Purchaser receives deposits from, makes payments on behalf of, or handles other financial transactions related to a Foreign Bank, the Purchaser represents and

warrants to the Company that: (1) the Foreign Bank has a fixed address, other than solely an electronic address, in a country in which the Foreign Bank is authorized to conduct banking activities; (2) the Foreign Bank maintains operating records related to its banking activities; (3) the Foreign Bank is subject to inspection by the banking authority that licensed the Foreign Bank to conduct banking activities; and (4) the Foreign Bank does not provide banking services to any other Foreign Bank that does not have a physical presence in any country and that is not a regulated Affiliate.

(k) The Purchaser or its duly authorized representative realizes that because of the inherently speculative nature of businesses of the kind conducted and contemplated by the Company, the Company’s financial results may be expected to fluctuate from month to month and from period to period and will, generally, involve a high degree of financial and market risk that could result in substantial or, at times, even total losses for investors in securities of the Company. The Purchaser has carefully read the risk factors and other information (including the financial statements of Exicure) included in the Super 8- K. The Purchaser has carefully considered such risk factors before deciding to invest in the Shares.

(l) The Purchaser has adequate means of providing for its current and anticipated financial needs and contingencies, is able to bear the economic risk for an indefinite period of time and has no need for liquidity of the investment in the Shares and could afford complete loss of such investment.

(m) The Purchaser is not subscribing for Shares as a result of or subsequent to any advertisement, article, notice or other communication, published in any newspaper, magazine or similar media or broadcast over television, radio, or the internet, or presented at any seminar or meeting, or any solicitation of a subscription by a person not previously known to the Purchaser in connection with investments in securities generally.

(n) The Purchaser acknowledges that no U.S. federal or state agency or any other government or governmental agency has passed upon the Shares or made any finding or determination as to the fairness, suitability or wisdom of any investments therein.

(o) Other than consummating the transactions contemplated hereunder, the Purchaser has not directly or indirectly, nor has any individual or entity acting on behalf of or pursuant to any understanding with such Purchaser, executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that such Purchaser first received a term sheet (written or oral) from the Company or any other individual or entity representing the Company setting forth the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Agreement. Other than to other individuals or entities party to this Agreement, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or

securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. For purposes of this Agreement, “Short Sales” means all “short sales” as defined in Rule 200 of Regulation SHO under the Exchange Act (but shall not be deemed to include the location and/or reservation of borrowable shares of Common Stock).

(p) The Purchaser agrees to be bound by all of the terms and conditions of the Registration Rights Agreement and to perform all obligations thereby imposed upon it.

(r) All of the information concerning the Purchaser set forth herein, and any other information furnished by the Purchaser in writing to the Company or a Placement Agent for use in connection with the transactions contemplated by this Agreement, is true and correct in all material respects as of the date of this Agreement, and, if there should be any material change in such information prior to the Purchaser’s purchase of the Shares, the Purchaser will promptly furnish revised or corrected information to the Company.

(s) The Purchaser has reviewed with its own tax advisors the U.S. federal, state, local and foreign tax consequences of this investment and the transactions contemplated by the Transaction Documents. With respect to such matters, such Purchaser relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral. The Purchaser understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the transactions contemplated by the Transaction Documents.

(t) If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), the Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Shares or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Shares; (b) any foreign exchange restrictions applicable to such purchase; (c) any governmental or other consents that may need to be obtained; and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Shares. The Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of the Purchaser’s jurisdiction.

(u) (For ERISA plans only) If the Purchaser is a fiduciary of the Employee Retirement Income Security Act of 1974 (“ERISA”) plan (the “Plan”), the Purchaser represents that (i) such fiduciary has been informed of and understands the Company’s investment objectives, policies and strategies, and that the decision to invest “plan assets” (as such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets and impose other fiduciary responsibilities; and (ii) the Purchaser fiduciary or Plan (a) is responsible for the decision to invest in the Company; (b) is independent of the Company or any of its Affiliates; (c) is qualified to make such investment decision; and (d) in making such decision, the Purchaser fiduciary or Plan has not relied primarily on any advice or recommendation of the Company or any of its Affiliates.

(v) Neither the Purchaser nor, to the Purchaser’s knowledge, any of its directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or managing members is subject to any Disqualification Events, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) under the Securities Act, and disclosed in writing in reasonable detail to the Company.

(w) The Purchaser understands that there are substantial restrictions on the transferability of the Shares and that the certificates representing the Shares shall bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such certificates or other instruments):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND NEITHER SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS, OR (2) AN EXEMPTION FROM SUCH REGISTRATION EXISTS AND THE COMPANY RECEIVES AN OPINION OF COUNSEL, WHICH COUNSEL AND OPINION ARE REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR TRANSFERRED IN THE MANNER CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS OR (3) SOLD PURSUANT TO RULE 144 UNDER THE SECURITIES ACT.

In addition, if any Purchaser is an Affiliate of the Company, certificates evidencing the Shares issued to such Purchaser may bear a customary “Affiliates” legend.

The Company shall be obligated to promptly reissue unlegended certificates upon the request of any holder thereof (x) at such time as the holding period under Rule 144 or another applicable exemption from the registration requirements of the Securities Act has been satisfied or (y) at such time as a registration statement is available for the transfer of the Shares. The Company is entitled to request from any holder requesting unlegended certificates under clause (x) of the foregoing sentence an opinion of counsel reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be so disposed of without registration, qualification or legend.

(x) If the Purchaser is an individual, then the Purchaser resides in the state or province identified in the address of the Purchaser set forth on such Purchaser’s Omnibus Signature Page to this Agreement; if the Purchaser is a partnership, corporation, limited liability company or other entity, then the office or offices of the Purchaser in which its principal place of business is identified in the address or addresses of the Purchaser set forth on such Purchaser’s Omnibus Signature Page to this Agreement.

(y) Each Purchaser understands that the Company prior to the Merger was a “shell company” as defined in Rule 12b-2 under the Exchange Act, and that upon filing with the SEC of the Super 8-K reporting the consummation of the Merger and related transactions and the transactions contemplated by this Agreement,

and otherwise containing “Form 10 information” discussed below, the Company will reflect therein that it is no longer a shell company. Pursuant to Rule 144(i), securities issued by a current or former shell company (that is, the Shares) that otherwise meet the holding period and other requirements of Rule 144 nevertheless cannot be sold in reliance on Rule 144 until one year after the Company (a) is no longer a shell company; and (b) has filed current “Form 10 information” (as defined in Rule 144(i)) with the SEC reflecting that it is no longer a shell company, and provided that at the time of a proposed sale pursuant to Rule 144, the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act and has filed all reports and other materials required to be filed by Section 13 or 15(d) of the Exchange Act, as applicable, during the preceding 12 months (or for such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports.

(a) The Company agrees to indemnify and hold harmless the Purchaser, and its directors, officers, stockholders, members, partners, employees and agents (and any other persons with a functionally equivalent role of a person holding such titles notwithstanding a lack of such title or any other title), each person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, stockholders, agents, members, partners or employees (and any other persons with a functionally equivalent role of a person holding such titles notwithstanding a lack of such title or any other title) of such controlling person (collectively, the “Purchaser Indemnitees”), from and against all losses, liabilities, claims, damages, costs, fees and expenses whatsoever (including, but not limited to, any and all

expenses incurred in investigating, preparing or defending against any litigation commenced or threatened) based upon or arising out of the Company’s breach of any representation, warranty or covenant contained herein; provided, however, that the Company will not be liable in any such case to the extent and only to the extent that any such loss, liability, claim, damage, cost, fee or expense arises out of or is based upon the inaccuracy of any representations made by such indemnified party in this Agreement, or the failure of such indemnified party to comply with the covenants and agreements contained herein. The liability of the Company under this paragraph shall not exceed the total Purchase Price paid by the Purchaser hereunder, except in the case of fraud.

(b) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any Action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 7 except to the extent the indemnified party is actually prejudiced by such omission. In case any such Action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, if the defendants in any such Action include both the indemnified party and the indemnifying party and either (i) the indemnifying party or parties and the indemnified party or parties mutually agree or (ii) representation of both the indemnifying party or parties and the indemnified party or parties by the same counsel is inappropriate under applicable standards of professional conduct due to actual or potential differing interests between them, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such Action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such Action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 7 for any reasonable legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed counsel in connection with the assumption of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel in such circumstance), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the Action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened Action in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such Action) unless such settlement, compromise or consent requires only the payment of money damages, does not subject the indemnified party to any continuing obligation or require any admission of criminal or civil responsibility, and includes an unconditional release of each indemnified party from all liability arising out of such Action, or (ii) be liable for any settlement of any such Action effected without its written consent (which consent shall not be

unreasonably withheld), but if settled with its written consent or if there be a final judgment of the plaintiff in any such Action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(c) Purchaser acknowledges on behalf of itself and each Purchaser Indemnitee that, other than for actions seeking specific performance of the obligations under this Agreement or in the case of fraud, the sole and exclusive remedy of the Purchaser and the Purchaser Indemnitee with respect to any and all claims relating to this Agreement shall be pursuant to the indemnification provisions set forth in this Section 7.

8. Price Based Anti-Dilution.

(a) The Purchaser (but not any transferees of the Shares) shall have anti-dilution protection such that if within eighteen (18) months after the Initial Closing the Company shall issue Additional Shares of Common Stock (as defined below) for a consideration per share, or with an exercise or conversion price per share, less than the Purchase Price (adjusted proportionately for any event described in clause (iii) of the following paragraph) occurring after the Initial Closing) (the “Lower Price”), the Purchaser shall be entitled to receive from the Company (for no additional consideration) additional Shares with respect to the Shares purchased by such Purchaser in the Offering and still held of record and beneficially owned by such Purchaser at the time of the dilutive issuance (such shares, together with the shares issued to the other purchasers pursuant to the other Subscription Agreements of like tenor used in the Offering, the “Held Shares”) in an amount such that, when added to the Held Shares held by the Purchaser, will equal the number of shares of Common Stock that such Purchaser’s aggregate Purchase Price for such Held Shares would have purchased at the Lower Price. Either (i) holders of a majority of the then Held Shares or (ii) a representative of the holders of the then Held Shares, which representative shall be appointed by the three (3) Purchasers who then hold the largest number of Held Shares, shall have the authority to waive these anti-dilution rights with respect to a particular issuance of securities for Purchaser and all other purchasers party to the other Subscription Agreements of like tenor used in the Offering (such persons described in either clause (i) or (ii) of this sentence, the “Anti-Dilution Requisite Party”). Notwithstanding the foregoing, the anti-dilution protection in this Section 8(a) shall automatically terminate upon the Company’s receipt of gross proceeds of forty million dollars ($40,000,000) or more in one or more related closings (the “Anti-Dilution Threshold”) in a bona fide transaction pursuant to which the Company issues shares of Common Stock and/or Additional Shares of Common Stock with the principal purpose of raising capital. For the avoidance of doubt, the gross proceeds from this Offering may be included in the Anti-Dilution Threshold.

(b) For the purposes of this Agreement, “Additional Shares of Common Stock” shall mean all shares of Common Stock issued by the Company after the Initial Closing (including without limitation any shares of Common Stock issuable upon conversion or exchange of any convertible securities or upon exercise of any option, warrant or other right, on an as-converted or as-exercised basis, as of the date of issuance of such security, option, warrant or right), other than: (i) shares of Common Stock issued or issuable upon conversion or exchange of any convertible securities or exercise of any options or warrants outstanding as of immediately following the Merger and the Initial Closing (including the Placement Agent Warrants); (ii) securities issued or issuable to strategic investors in connection with an acquisition, collaboration, joint venture, technology license agreement or

other strategic transaction; (iii) shares of Common Stock issued or issuable by reason of a stock dividend, stock split, split-up or other distribution on shares of Common Stock relating to any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets or other transaction effected in such a way that there is no change of control; (iv) securities of the Company issued or issuable pursuant to the acquisition of another entity or business by the Company by merger, purchase of substantially all of the assets or other reorganization, but not including a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities; (v) issuances of Common Stock, options of other equity awards to officers, directors and employees of, or consultants to, the Company pursuant to the Company’s 2017 Equity Incentive Plan or its 2017 Employee Stock Purchase Plan or assumed by the Company in connection with the Merger, or upon exercise of options or warrants granted to such parties pursuant to such plans or such arrangements assumed by the Company in connection with the Merger; and (vi) securities issued to financial institutions, institutional investors or lessors in connection with credit arrangements, equipment financings, lease arrangements or similar transactions, in the aggregate not exceeding ten percent (10%) of the number of shares of Common Stock outstanding at the time of such issuance.

9. Revocability; Binding Effect. The subscription hereunder may be revoked prior to the First Subsequent Closing or any Subsequent Closing, as applicable, thereon, provided that written notice of revocation is sent and is received by the Company or a Placement Agent at least one Business Day prior to the First Subsequent Closing or any Subsequent Closing, as applicable, on such subscription. The Purchaser hereby acknowledges and agrees that this Agreement shall survive the death or disability of the Purchaser and shall be binding upon and inure to the benefit of the parties and their heirs, executors, administrators, successors, legal representatives and permitted assigns. If the Purchaser is more than one person, the obligations of the Purchaser hereunder shall be joint and several and the agreements, representations, warranties and acknowledgments herein shall be deemed to be made by and be binding upon each such person and such person’s heirs, executors, administrators, successors, legal representatives and permitted assigns. For the purposes of this Agreement, “Business Day” means a day, other than a Saturday or Sunday, on which banks in Xxx Xxxx Xxxx, Xxxx Xxxx, Xxxxxxxxx and the People’s Republic of China are open for the general transaction of business.

10. Next Equity Financing. From the date of the First Subsequent Closing through the Long Stop Date, if the Company issues or sells any Additional Shares of Common Stock from which the Company receives gross proceeds of two million five hundred thousand dollars ($2,500,000) or more in one or more related closings (the “Next Equity Financing”) with terms and conditions, including price, more favorable to the holder of such security in the Next Equity Financing than the terms and conditions set forth in this Agreement, including the Purchase Price, then the Company shall promptly provide the Purchaser with written notice of such fact (and the relevant terms and conditions) and, unless otherwise agreed by the Company and the Purchaser, this Agreement, without any further action of the Company or the Purchaser, shall be deemed automatically amended and modified to include such more favorable terms such that the Purchaser shall receive the benefit of such more favorable terms. To the extent the terms and conditions, including price, applicable to any investor in the Initial Closing are more favorable than the terms and conditions set forth in this Agreement, the Company shall promptly provide the Purchaser

with written notice of such fact (and the relevant terms and conditions) and, unless otherwise agreed by the Company and the Purchaser, this Agreement, without any further action of the Company or the Purchaser, shall be deemed automatically amended and modified to include such more favorable terms such that the Purchaser shall receive the benefit of such more favorable terms. To the extent an investor in the Next Equity Financing receives securities other than shares of Common Stock, then the Purchaser shall have the right to exchange its then Held Shares (for no additional consideration) for the amount of securities equal to the aggregate Purchase Price for the then Held Shares. For clarity, any Subsequent Closing pursuant to the same terms of this Agreement (other than necessary changes of name, address and/or amount of aggregate (but not per share) Purchase Price) shall not be a Next Equity Financing.

11. Miscellaneous.

(a) Modification. This Agreement shall not be amended, modified or waived except by an instrument in writing signed by the Company and the holders of at least a majority of the then Held Shares (as defined above), provided that Section 8 of this Agreement shall not be amended or modified except by an instrument in writing signed by the Company and the Anti-Dilution Requisite Party (as defined above).

(o) This Agreement may be executed in one or more original or facsimile or by an e-mail which contains a portable document format (.pdf) file of an executed signature page counterparts, each of which shall be deemed an original, but all of which shall together constitute one and the same instrument and which shall be enforceable against the parties actually executing such counterparts. The exchange of copies of this Agreement and of signature pages by facsimile transmission or in .pdf format shall constitute effective execution and delivery of this Agreement as to the parties and may be used in lieu of the original Agreement for all purposes. Signatures of the parties transmitted by facsimile or by e- mail of a document in pdf format shall be deemed to be their original signatures for all purposes.

(p) Each provision of this Agreement shall be considered separable and, if for any reason any provision or provisions hereof are determined to be invalid or contrary to applicable law, such invalidity or illegality shall not impair the operation of or affect the remaining portions of this Agreement.

(q) Paragraph titles are for descriptive purposes only and shall not control or alter the meaning of this Agreement as set forth in the text.

(r) The Purchaser understands and acknowledges that there may be multiple Subsequent Closings for the Offering.

(s) The Purchaser hereby agrees to furnish the Company such other information as the Company may request prior to the First Subsequent Closing or any Subsequent Closing, as applicable, with respect to its subscription hereunder.

(u) Omnibus Signature Page. This Agreement is intended to be read and construed in conjunction with the Registration Rights Agreement. Accordingly, pursuant to the terms and conditions of this Agreement and the Registration Rights Agreement, it is hereby agreed that the execution by the Purchaser of this Agreement, in the place set forth on the Omnibus Signature Page below, shall constitute agreement to be bound by the terms and conditions hereof and the terms and conditions of the Registration Rights Agreement, with the same effect as if each of such separate but related agreement were separately signed.

(v) Public Disclosure. Neither the Purchaser nor any officer, manager, director, member, partner, stockholder, employee, Affiliate, Affiliated person or entity of the Purchaser shall make or issue any press releases or otherwise make any public statements or make any disclosures to any third person or entity with respect to the transactions contemplated herein and will not make or issue any press releases or otherwise make any public statements of any nature whatsoever with respect to the Company without the Company’s express prior approval (which may be withheld in the Company’s sole discretion), except to the extent such disclosure is required by law, request of the staff of the SEC or of any regulatory agency or principal trading market regulations.

(w) Potential Conflicts. The Placement Agents, their sub-agents, legal counsel to the Company, the Placement Agents or Exicure and/or their respective Affiliates, principals, representatives or employees may now or hereafter own shares of the Company.

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

(y) Waiver of Conflicts. Each party to this Agreement acknowledges that Sidley Austin LLP, counsel for the Company, has in the past performed and may continue to perform legal services for certain of the Purchasers in matters unrelated to the transactions described in this Agreement, including financings and other matters. Accordingly, each party to this Agreement hereby (a) acknowledges that they have had an opportunity to ask for information relevant to this disclosure; (b) acknowledges that Sidley Austin LLP represented the Company in the transaction contemplated by this Agreement and has not represented any individual Purchaser in connection with such transaction; and (c) gives its informed consent to Sidley Austin LLP’s representation of certain of the Purchasers in such unrelated matters and to Sidley Austin LLP’s representation of the Company in connection with this Agreement and the transactions contemplated hereby.

ANTI MONEY LAUNDERING REQUIREMENTS

The USA PATRIOT Act

The USA PATRIOT Act is designed to detect, deter, and punish terrorists in the United States and abroad. The Act imposes new anti-money laundering requirements on brokerage firms and financial institutions. Since April 24, 2002 all brokerage firms have been required to have new, comprehensive anti-money laundering programs.

To help you understand these efforts, we want to provide you with some information about money laundering and our steps to implement the USA PATRIOT Act.

What is money laundering?

Money laundering is the process of disguising illegally obtained money so that the funds appear to come from legitimate sources or activities. Money laundering occurs in connection with a wide variety of crimes, including illegal arms sales, drug trafficking, robbery, fraud, racketeering, and terrorism.

How big is the problem and why is it important?

The use of the U.S. financial system by criminals to facilitate terrorism or other crimes could well taint our financial markets. According to the U.S. State Department, one recent estimate puts the amount of worldwide money laundering activity at $1 trillion a year.

What are we required to do to eliminate money laundering?

Under rules required by the USA PATRIOT Act, our anti-money laundering program must designate a special compliance officer, set up employee training, conduct independent audits, and establish policies and procedures to detect and report suspicious transaction and ensure compliance with such laws. As part of our required program, we may ask you to provide various identification documents or other information. Until you provide the information or documents we need, we may not be able to effect any transactions for you.

ANTI-MONEY LAUNDERING INFORMATION FORM

The following is required in accordance with the AML provision of the USA PATRIOT ACT.
