EXHIBIT 10.1


WARRANT EXERCISE AGREEMENT
This Warrant Exercise Agreement (this “Agreement”), dated as of March 6, 2019, is by and between SELLAS Life Sciences Group, Inc., a Delaware corporation (the “Company”), and the undersigned holder (the “Holder”) of warrants to purchase shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”).
WHEREAS, the Holder beneficially owns in the aggregate the number of warrants to purchase Common Stock with an exercise price of $2.10 per share that are exercisable until July 16, 2023, as set forth on the Holder's signature page hereto (the “Original Warrants”). 
WHEREAS, in order to induce the Holder to exercise certain of the Original Warrants, the Company and the Holder desire to amend the Original Warrants to reduce the exercise price thereof to $1.10 per share;
WHEREAS, the Holder desires to exercise certain of such Original Warrants in the amounts set forth on the applicable signature pages hereto using the Amended Exercise Price (as defined below) and, immediately prior to such exercise and in consideration of the Holder’s exercise of such Original Warrants, the Company has agreed to issue the Holder, in addition to the shares of Common Stock to which such exercising Holder is entitled pursuant to the exercise of such Original Warrants, an equal number of new warrants as the number of Original Warrants being exercised in the form attached hereto as Exhibit A (the “New Warrants”).  The shares of Common Stock underlying the Original Warrants are referred to herein as the “Warrant Shares”.  The shares of Common Stock underlying the New Warrants are referred to herein as the “New Warrant Shares” and collectively with the New Warrants and Warrant Shares, the “Securities”.
NOW, THEREFORE, IN CONSIDERATION of the mutual covenants contained in this Agreement, and for good and valuable consideration the receipt and adequacy of which are hereby acknowledged, the Holder and the Company agree as follows: 
ARTICLE I
DEFINITIONS
Section 1.1 Definitions.   Capitalized terms not defined in this Agreement shall have the meanings ascribed to such terms in the New Warrants.  
ARTICLE II
AMENDMENT AND EXERCISE OF ORIGINAL WARRANTS
Section 2.1 Amendment of Original Warrants.  (a) On the date hereof, the reference to “$2.10 per share” in the defined term “Exercise Price” set forth in Section 1(b) of the Original Warrants shall be amended and restated as follows: “$1.10 per share, provided that this Warrant is exercised prior to 5:00 p.m. EST on May 31, 2019; otherwise, such Exercise Price shall be $2.10 per share” (the “Amended Exercise Price”).
(b) All references to the Original Warrants used herein, after the execution of this Agreement, shall refer to the Original Warrants, as amended pursuant to clause (a) above.  Except as expressly set forth in this Agreement, all terms of the Original Warrants are, and shall continue to be, in full force and effect and are hereby ratified and confirmed in all respects, and the Holder reserves all of its rights, remedies, powers and privileges.











Section 2.2 Exercise of Warrants.   (a) By executing this Agreement, the Company and the Holder hereby agree that the Holder shall be deemed to have exercised the number of Original Warrants set forth on the signature page hereto for aggregate cash proceeds to the Company in the amount set forth on the Holder’s signature page hereto, pursuant to the terms of the Original Warrants, except that the exercise price thereunder shall be the Amended Exercise Price.  The Holder shall deliver the aggregate cash exercise price for such Original Warrants to the bank account set forth on the Company’s signature page hereto within two Trading Days after the date hereof and promptly after receipt of such funds, the Company shall deliver the Warrant Shares to the Holder via the Depository Trust Company Deposit or Withdrawal at Custodian system pursuant to the terms of the Original Warrants, but pursuant to DWAC instructions set forth on the Holder’s signature page hereto. The date of the closing of the initial exercise of the Original Warrants shall be referred to as the “Closing Date.”  
(b) After the Closing Date, until the Original Warrants are exercised in full, if and whenever the Holder, together with its Attribution Parties (as defined in Section 1(f) of the Original Warrants), can exercise at least 1,000,000 of the remaining Original Warrants (or such smaller number of Original Warrants as is remaining) in compliance with the Maximum Percentage, the Holder hereby covenants and agrees to promptly notify the Company of such event and to promptly exercise for cash at least such number of the remaining Original Warrants (or such smaller number of Original Warrants as is remaining) held by it by delivery of a Notice of Exercise pursuant to the terms and conditions of the applicable Original Warrants.  The parties hereto further agree that the Holder may voluntarily exercise for cash, from time to time, the Original Warrants pursuant to the terms and conditions of the applicable Original Warrants.
Section 2.3 Issuance of New Warrants. Within two Trading Days of the Closing Date, the Company shall deliver to the Holder the New Warrants to which the Holder is entitled.   The Holder shall be entitled to receive a New Warrant issuable for the identical number of shares of Common Stock as the Holder exercises for cash pursuant to Section 2.2(a) above.  Within two Trading Days of the exercise of any remaining Original Warrants for cash prior to May 31, 2019 (the “Termination Date”), whether such exercise is required under this Agreement, or is at the election of the Holder, the Company shall deliver to the Holder one New Warrant issuable for the identical number of remaining Original Warrants exercised.  The obligations under Section 2.3 shall terminate on the Termination Date.
 
Section 2.4 Legends; Restricted Securities.    (a) The Holder understands that the New Warrants and the shares of Common Stock underlying New Warrants are not, and may never be, registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state and, accordingly, each certificate, if any, representing such securities shall bear a legend substantially similar to the following:
“NEITHER THIS SECURITY NOR THE SECURITIES FOR WHICH THIS SECURITY IS EXERCISABLE HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.”











(b) Certificates evidencing shares of Common Stock underlying the New Warrants shall not contain any legend (including the legend set forth in Section 2.4(a) hereof), (i) while a registration statement covering the resale of such Common Stock is effective under the Securities Act, (ii) following any sale of such Common Stock pursuant to Rule 144, (iii) if such Common Stock is eligible for sale under Rule 144 (assuming cashless exercise of the New Warrants), without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Common Stock and without volume or manner-of-sale restrictions, (iv) if such Common Stock may be sold under Rule 144 (assuming cashless exercise of the New Warrants) and the Company is then in compliance with the current public information required under Rule 144 as to such Common Stock, or (v) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Securities and Exchange Commission (the “Commission”)). The Company shall cause its counsel to issue a legal opinion to the transfer agent promptly after the Delegend Date (as defined below) if required by the Company and/or the transfer agent to effect the removal of the legend hereunder, which opinion shall be in form and substance reasonably acceptable to the Holder. If such Common Stock may be sold under Rule 144 (assuming cashless exercise of the New Warrants) without the requirement for the Company to be in compliance with the current public information required under Rule 144 or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission), then such Common Stock shall be issued free of all legends. The Company agrees that following the Delegend Date or at such time as such legend is no longer required under this Section 2.4(b), it will, no later than two (2) Trading Days following the delivery by the Holder to the Company or the transfer agent of a certificate representing the Common Stock underlying the New Warrants issued with a restrictive legend (such second Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to the Holder a certificate representing such shares that is free from all restrictive and other legends or, at the request of the Holder shall credit the account of the Holder’s prime broker with the Depository Trust Company System as directed by the Holder. The Company may not make any notation on its records or give instructions to the transfer agent that enlarge the restrictions on transfer set forth in this Section 2.4(b).   “Delegend Date” means the earliest of the date that (a) a registration statement with respect to the Common Stock has been declared effective by the Commission or (b) all of the Common Stock has been sold pursuant to Rule 144 or may be sold pursuant to Rule 144 without the requirement for the Company to be in compliance with the current public information required under Rule 144 and without volume or manner-of-sale restrictions or (c) following the six (6) month anniversary of (I) the Closing Date, if a New Warrant is exercised pursuant to a cashless exercise, or (II) the date of the related cash exercise of the New Warrants provided, in each case, that the applicable holder of the New Warrants or the Common Stock, as the case may be, is not an Affiliate of the Company, the Company is in compliance with the current public information required under Rule 144 (“Current Public Information Requirement”) and all such Common Stock may be sold pursuant to Rule 144 or an exemption from registration under Section 4(a)(1) of the Securities Act without volume or manner-of-sale restrictions; provided, further, however, that if the Company fails to comply with the Current Public Information Requirement at any time following the applicable six (6) month anniversary set forth above and the one (1) year anniversary of the Closing Date, the Company shall promptly provide notice to the Holder and the Holder undertakes not to sell such Common Stock pursuant to Rule 144 until the Company notifies the Holder that it has regained compliance with the Current Public Information Requirement; and provided further, that if a delegending is in effect solely as the result of the effectiveness of a registration statement covering the resale of any Common Stock, the Holder undertakes not to sell any such Common Stock if the Holder is notified or otherwise becomes aware that such registration statement has been withdrawn or suspended, contains a material misstatement or omission or has become stale.  The Holder agrees with the Company that the Holder will only sell or transfer any New Warrants or shares of Common Stock underlying New Warrants pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein, and the Holder acknowledges that the removal of the restrictive legend from certificates representing any such securities as set forth in this Section 2.4 or otherwise is predicated upon the Company’s reliance upon this understanding.  











Section 2.4 Filing of Form 8-K. Prior to 9:00 am ET on March 6, 2019, the Company shall issue a Current Report on Form 8-K, reasonably acceptable to the Holder disclosing the material terms of the transactions contemplated hereby, which shall include this form of Agreement (the “8-K Filing”). From and after the issuance of the 8-K Filing, the Company represents to the Holder that the Holder shall not be in possession of any material, nonpublic information received from the Company, any of its Subsidiaries (as defined below) or any of their respective officers, directors, employees or agents, that is not disclosed in the 8-K Filing. In addition, effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, on the one hand, and the Holder or any of its Affiliates, on the other hand, shall terminate.  The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide the Holder with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the date hereof without the express prior written consent of the Holder. To the extent that the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, delivers any material, non-public information to the Holder without the Holder’s consent, the Company hereby covenants and agrees that the Holder shall not have any duty of confidentiality with respect to such material, non-public information.  As used herein, “Subsidiary” means any subsidiary of the Company, and shall, where applicable, also include any direct or indirect subsidiary of the Company formed or acquired after the date hereof.

The Company shall use commercially reasonable efforts to keep the Registration Statement effective and available for the issuance of the Warrant Shares underlying the Original Warrants until all Original Warrants are exercised.  If the Company is unable to keep the Registration Statement effective and available despite their commercially reasonable efforts, either the Company or the Holder may, by delivering written notice to the other, terminate all remaining obligations under this Agreement.  











(d) No Conflicts. The execution, delivery and performance of this Agreement by the Company and the consummation by the Company of the transactions contemplated hereby do not and will not: (i) conflict with or violate any provision of the Company’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, result in the creation of any lien upon any of the properties or assets of the Company, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any material agreement, credit facility, debt or other material instrument (evidencing Company debt or otherwise) or other material understanding to which the Company is a party or by which any property or asset of the Company is bound or affected, or (iii) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company is bound or affected, except in the case of each of clauses (ii) and (iii), such as would not have or reasonably be expected to result in (i) a material adverse effect on the legality, validity or enforceability of this Agreement, (ii) a material adverse effect on the results of operations, assets, business or condition (financial or otherwise) of the Company and its subsidiaries, taken as a whole, or (iii) a material adverse effect on the Company's ability to perform in any material respect on a timely basis its obligations under this Agreement (any of (i), (ii) or (iii), a “Material Adverse Effect”).
(e) Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by this Agreement, the Company confirms that neither it nor any other Person acting on its behalf has provided any of Holder or their agents or counsel with any information that it believes constitutes or might constitute material, non-public information. The Company understands and confirms that the Holder will rely on the foregoing representation in effecting transactions in securities of the Company. As of the date of this Agreement, all of the disclosure when furnished by or on behalf of the Company to the Holder regarding the Company and its Subsidiaries, their respective businesses and the transactions contemplated hereby, including but not limited to the disclosure set forth in the SEC Reports, is true and correct in all material respects and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

As of the Closing Date, a number of shares of Common Stock shall have been duly authorized and reserved for issuance which equals or exceeds the maximum number of Warrant Shares issuable upon exercise of the New Warrants (without taking into account any limitations on the exercise of the New Warrants set forth therein).  Upon exercise of the New Warrants in accordance with the New Warrants, the New Warrant Shares when issued will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights, taxes, liens, charges and other encumbrances with respect to the issue thereof, other than restrictions on transfer under applicable state and federal securities laws and liens or encumbrances created by or imposed by the Holder, with the holders being entitled to all rights accorded to a holder of Common Stock.  Assuming the accuracy of each of the representations and warranties set forth in Section 3.2 of this Agreement, the offer and issuance by the Company of the New Warrants is exempt from registration under the 1933 Act.

(h) No Integrated Offering.  None of the Company, its Subsidiaries or any of their Affiliates, nor any Person acting on 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 issuance of any of the New Warrants or the New Warrant Shares (collectively, the “New Securities”) under the Securities Act, whether through integration with 











prior offerings or otherwise, or cause this offering of the New Securities to require approval of shareholders of the Company for purposes of the Securities Act or any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of the Nasdaq Stock Market.  None of the Company, its Subsidiaries, their Affiliates nor any Person acting on their behalf will take any action or steps that would require registration of the issuance of any of the New Securities under the Securities Act or cause the offering of any of the New Securities to be integrated with other offerings for purposes of any such applicable shareholder approval provisions.

With respect to Securities to be offered and sold hereunder in reliance on Rule 506(b) under the Securities Act  (“Regulation D Securities”), none of the Company, any of its predecessors, any affiliated issuer, any director, executive officer, other officer of the Company participating in the offering hereunder, any beneficial owner of 20% or more of the Company's outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under the Securities Act) connected with the Company in any capacity at the time of sale (each, an “Issuer Covered Person” and, together, “Issuer Covered Persons”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (a “Disqualification Event”), except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3). The Company has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification Event.  The Company has complied, to the extent applicable, with its disclosure obligations under Rule 506(e), and has furnished to the Holder a copy of any disclosures provided thereunder.
Section 3.2 Representations and Warranties of the Holder. The Holder hereby makes the representations and warranties set forth below to the Company that as of the date of its execution of this Agreement.  
(a) Organization; Due Authorization.  The Holder is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder. The Holder represents and warrants that (i) the execution and delivery of this Agreement by it and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary action on its behalf and (ii) this Agreement has been duly executed and delivered by the Holder and constitutes the valid and binding obligation of the Holder, enforceable against it in accordance with its terms. 
(b) Understandings or Arrangements. The Holder is acquiring the Securities as principal for its own account and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this representation and warranty not limiting the Holder’s right to sell the Securities pursuant to a registration statement or otherwise in compliance with applicable federal and state securities laws). The Holder is acquiring the Securities hereunder in the ordinary course of its business.
(c) No Conflicts.  The Holder represents and warrants that the execution, delivery and performance of this Agreement by the Holder and the consummation by the Holder of the transactions contemplated hereby do not and will not: (i) conflict with or violate any provision of the Holder’s organizational or charter documents, or (ii) conflict with or result in a violation of any agreement, law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority which would interfere with the ability of the Holder to perform its obligations under this Agreement. 











(d)  Access to Information.  The Holder acknowledges that it has had the opportunity to review this Agreement and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the exercise of the Original Warrants and the merits and risks of investing in the Warrant Shares, the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. The Holder acknowledges and agrees that neither Oppenheimer & Co., Inc. (the “Advisor”) nor any Affiliate of the Advisor has provided the Holder with any information or advice with respect to the Securities nor is such information or advice necessary or desired. Neither the Advisor nor any Affiliate has made or makes any representation as to the Company or the quality of the securities issued and issuable hereunder and the Advisor and any Affiliate may have acquired non-public information with respect to the Company which the Holder agrees need not be provided to it. In connection with the issuance of the securities hereunder to the Holder, neither the Advisor nor any of its Affiliates has acted as a financial advisor or fiduciary to the Holder. 
 
(e)  Holder Status.  The Holder represents and warrants that at the time the Holder was offered the Securities, it was, and as of the date hereof it is, and on each date on which it exercises any New Warrants, it was or will be an “accredited investor” as defined in Rule 501 under the Securities Act. 
 
(f)  Knowledge.  The Holder, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Warrant Shares, and has so evaluated the merits and risks of such investment. The Holder is able to bear the economic risk of an investment in the Warrant Shares and, at the present time, is able to afford a complete loss of such investment.
ARTICLE IV
MISCELLANEOUS
 
Section 4.1 Subsequent Equity Sales. 
(a) From the date hereof until May 20, 2019 (the “Restricted Period”), neither the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents; provided however, that such Restricted Period shall terminate on the Trading Day following the date that the Common Stock’s Closing Sale Price (each as defined in the New Warrants) exceeds $1.83 (subject to adjustment for forward and reverse stock splits and the like) for a period of 10 consecutive Trading Days.  As used herein, “Common Stock Equivalents” means any securities of the Company or the Subsidiaries which would entitle the holder thereof to acquire at any time Common Stock, including, without limitation, any debt, preferred stock, right, option, warrant or other instrument that is at any time convertible into or exercisable or exchangeable for, or otherwise entitles the holder thereof to receive, Common Stock.  In addition, if the Restricted Period has not been earlier terminated pursuant to the proviso in the first sentence this Section 4.1(a), from the date hereof until May 20, 2019, the Company shall not, directly or indirectly, file any registration statement with the Securities and Exchange Commission (“SEC”), or file any amendment or supplement thereto or cause any registration statement or amendment thereto to be declared effective by the SEC, or grant any registration rights to any Person that can be exercised prior to such time as set forth above; provided however, that the foregoing shall not prevent the Company from filing during the Restricted Period a registration statement on Form S-8.
 











(b) Notwithstanding the foregoing, this Section 4.1 shall not apply in respect of an Exempt Issuance.  “Exempt Issuance” means the issuance of (a) shares of Common Stock or options to employees, officers or directors of the Company pursuant to any stock or option plan duly adopted for such purpose, by a majority of the non-employee members of the Board of Directors or a majority of the members of a committee of non-employee directors established for such purpose for services rendered to the Company, (b) securities upon the exercise or exchange of or conversion of any Securities issued hereunder and/or other securities exercisable or exchangeable for or convertible into shares of Common Stock issued and outstanding on the date of this Agreement, provided that such securities have not been amended since the date of this Agreement to increase the number of such securities or to decrease the exercise price, exchange price or conversion price of such securities (other than in connection with stock splits or combinations) or to extend the term of such securities, and (c) securities issued pursuant to acquisitions or strategic transactions approved by a majority of the disinterested directors of the Company, provided that any such issuance shall only be to a Person (or to the equity holders of a Person) which is, itself or through its subsidiaries, an operating company or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits in addition to the investment of funds, but shall not include 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; provided, that such securities are issued as “restricted securities” (as defined in Rule 144) and the recipients of such securities are not granted registration rights that enable or require the filing of a resale registration statement until after the time period specified in the first sentence of Section 4.1(a) above.
Section 4.2 Public Information.  At any time commencing on the six (6) month anniversary of the date hereof and ending when no New Warrants remain outstanding, if there is no effective registration statement covering the resale of the New Warrant Shares and the Company (i) shall fail for any reason to satisfy the current public information requirement under Rule 144(c) or (ii) the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”), then, in addition to such Holder’s other available remedies, the Company shall pay to a Holder, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the New Warrant Shares, an amount in cash equal to two percent (2.0%) of the product of (i) the maximum number of New Warrant Shares issuable upon a cash exercise of the New Warrants and (ii) the last Closing Sale Price less the Exercise Price of the New Warrants immediately prior to the time of the initial Public Information Failure and on every thirtieth (30th) day (pro-rated for periods totaling less than thirty (30) days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public information is no longer required for the Holders to transfer the New Warrant Shares pursuant to Rule 144.  The payments to which a Purchaser shall be entitled pursuant to this Section 4.2 are referred to herein as “Public Information Failure Payments.”  Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd) Trading Day after the event or failure giving rise to the Public Information Failure Payments is cured.  In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (pro-rated for partial months) until paid in full. Nothing herein shall limit such Holder’s right to pursue actual damages for the Public Information Failure, and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.
Section 4.3 Resale Registration Statement. The Company reserves the right at any time to file and cause to become effective a registration statement covering the resale of the New Warrant Shares.  Holder hereby covenants and agrees to promptly provide the Company with any material information that is reasonably required to be provided in such registration statement with respect to such Holder, including the completion, execution, acknowledgement and delivery of customary selling stockholder questionnaires and other documents, certificates, instruments, representations and warranties and indemnities as may be reasonably requested by the Company in connection with the filing of such registration statement, including, without limitation, representations and warranties (or indemnities with respect thereto) in connection with (i) Holder’s ownership of New Warrant Shares to be transferred free and clear of all liens, claims and encumbrances, (ii) Holder’s power and authority to effect such transfer, and (iii) such matters pertaining to compliance with applicable law by Holder. The Company may require Holder, by written notice given to Holder not less than seven (7) Trading Days prior to the filing date of a registration statement, to promptly, and in any event within five (5) Trading Days after receipt of such notice, furnish in writing to the Company such information 











regarding the distribution of the New Warrant Shares as the Company may from time to time reasonably request and such other information as may be legally required in connection with such registration.  Notwithstanding anything to the contrary contained herein, (i) the provisions of this Section 4.3 shall not be applicable to the extent that the Holder is required to be named as an underwriter in any resale registration statement, and (ii) any indemnities required to be provided in this Section 4.3 by the Holder shall apply solely with respect to written information provided by the Holder specifically for use in such registration statement, and such indemnities shall be limited to net proceeds received by such Holder with respect to sales of New Warrant Shares.
Section 4.4 Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be made by email to the email address of the Holder set forth on Holders’ signature page. 
Section 4.5 Survival. All warranties and representations (as of the date such warranties and representations were made) made herein or in any certificate or other instrument delivered by it or on its behalf under this Agreement shall be considered to have been relied upon by the parties hereto and shall survive the issuance of the New Warrants. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties; provided however that no party may assign this Agreement or the obligations and rights of such party hereunder without the prior written consent of the other parties hereto. 
Section 4.6 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart.
