PURCHASE AND SALE AND INVESTMENT

2.1 Note Purchase. The Purchaser will purchase the Note from the Company in the aggregate Principal Amount of Five Million Dollars ($5,000,000).

2.3 Investment. (a) Subject to Section 2.3(d), in the sole discretion of the Company, the Purchaser shall purchase up to $5,000,000 of the Company’s securities (the “Investment”) on the same terms and conditions as the other investors in the Qualified Financing. At least ten (10) days prior to the closing of the Qualified Financing, the Company or the underwriter or placement agent shall provide the Purchaser with notice of the terms of the Qualified Financing.

(b) Subject to Section 2.3(d) below, if the Qualified Financing referred to in Section 2.3(a) has not occurred before the Successful Completion of the Futility Analysis (as described in Section 2.4(B) of the Option and Collaboration Agreement), the Investment would be made, in the sole discretion of the Company, and subject to the satisfaction of the conditions set forth in Section 2.7 below, in the form of an additional convertible promissory note in the principal amount of $5,000,000 (the “Subsequent Note”) whereby the Purchaser would purchase the Subsequent Note upon the same terms and conditions as set forth in the Note, which terms shall, except as otherwise agreed in writing by the parties, be identical to the Note, except that the maturity date of the Subsequent Note shall be the third anniversary of the issuance date of the Subsequent Note.

Accordingly, the maximum amount that Purchaser can be obligated to invest pursuant to Section 2.3(a) would be the lesser of (i) $5,000,000 and (ii) such amount as would result in Purchaser’s ownership being at or below the Threshold; provided, that an Investment in a Qualified Financing that is an IPO is not subject to this Section 2.3(d). Any remaining amount of Purchaser’s $5,000,000 Investment commitment would simultaneously be invested in a Subsequent Note pursuant to Section 2.3(b) above.

At the Closing, the Purchaser shall deliver to the Company, via wire transfer in immediately available funds an amount equal to the Purchaser’s Subscription and Option Amount, the Company shall deliver to the Purchaser its Note, and the Company and the Purchaser shall deliver the other items set forth in Section 2.5 deliverable at such Closing.

(x) Material Agreements. Set forth on Exhibit 3.1(x) is a list of any and all material contracts, instruments, agreements, commitments, obligations, plans or arrangements, to which the Company and any Subsidiary is a party. Each of the Company and any Subsidiary has in all respects performed all the obligations required to be performed by them to date under the foregoing agreements, have received no notice of default and are not in default under any such agreement now in effect, except where the failure to so perform or the default would not cause a Material Adverse Effect.

(z) Disclosure. The Company has made available to the Purchaser all of the information reasonably available to the Company that the Purchaser has requested for deciding whether to acquire the Securities, and all such materials were prepared in good faith. No representation or warranty of the Company contained in this Agreement, as qualified by the Disclosure Schedule, and no certificate furnished or to be furnished to the Purchaser at the Closing contains any untrue statement of a material fact or, to the Company’s Knowledge, omits to state a material fact necessary in order to make the statements contained herein or therein not misleading in light of the circumstances under which they were made. It is understood that this representation is qualified by the fact that the Company has not delivered to the Purchaser, and has not been requested to deliver, a private placement or similar memorandum or any written disclosure of the types of information customarily furnished to purchasers of securities.

3.2 Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants as of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein):

(a) Organization; Authority. The Purchaser is an entity duly formed, validly existing and in good standing under the laws of the jurisdiction of its formation with full right, corporate or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary limited liability company or similar action, as applicable, on the part of the Purchaser. Each Transaction Document to which it is a party has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally; (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies; and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(b) Own Account. The Purchaser understands that the Securities are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law and is acquiring the Securities as principal for its own account and not with a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable state securities law (this representation and warranty not limiting the Purchaser’s right to sell the Securities or any security into which they are converted or exchanged in compliance with applicable federal and state securities laws). The Purchaser is acquiring the Securities hereunder in the ordinary course of its business.

(c) Purchaser Status. At the time the Purchaser was offered the Securities, it was, and as of the date hereof it is, an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act.

(d) Experience of the Purchaser. The Purchaser, 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 Securities, and has so evaluated the merits and risks of such investment. The Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

(e) General Solicitation. The Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

(f) Confidentiality. Other than to other Persons party to this Agreement and to the Purchaser’s employees, officers, directors, attorneys and advisors, the Purchaser has maintained and will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

(g) Full Access. The Purchaser has had a reasonable opportunity to ask questions of and receive information and answers from a person or persons acting on behalf of the Company concerning the Securities and has had an opportunity to conduct a due diligence investigation of the Company. The Purchaser has reviewed the Company’s registration statement on Form S-1 filed with the Commission on December 23, 2015 and understands and acknowledges that there can be no assurance that such registration statement will be declared effective by the Commission or that the IPO for which the shares are being registered will be consummated.

The Company acknowledges and agrees that the representations contained in Section 3.2 shall not modify, amend or affect the Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1 Transfer Restrictions.

(a) The Securities may only be disposed of in compliance with state and federal securities laws.

(b) The Purchaser agrees to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Securities in the following form:

THIS SECURITY AND THE SECURITIES ISSUABLE UPON THE CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), or the securities laws of any other state or jurisdiction. They may not be purchased with a view for distribution or resale, and may only be offered, sold, mortgaged, pledged, hypothecated, or otherwise transferred in compliance with either an effective registration statement for such security under the SECURITIES act or any applicable state securities act, or an opinion of counsel for the company that registration is not required under SECURITIES act or the laws of any other jurisdiction.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN THE SECURITIES PURCHASE AGREEMENT BETWEEN THE COMPANY AND THE PURCHASER, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

4.2 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities.

4.3 Disclosure; Publicity. (a) The Company and the Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor the Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company, with respect to any press release of the Purchaser, or without the prior consent of the Purchaser, with respect to any press release of the Company, and each such consent shall not unreasonably be withheld or delayed, except if such disclosure is required by securities laws or rules, including those promulgated by the Commission, or any rules or requirements of stock exchanges on which equity securities of each of the Company and the Purchaser may be listed, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement, disclosure or communication. For the avoidance of doubt, the Purchaser understands that the U.S. federal securities laws generally require any company that is publicly held or that is registering its securities for public sale to disclose a broad range of financial and non-financial information in registration statements, annual reports and other filings made with the Commission. As a result, copies of this Agreement and the Note and descriptions thereof may be made public in the sole discretion of the Company or the Purchaser in order to comply with such securities laws and the rules and regulations of the Commission.

The Company shall use the net proceeds hereunder primarily to fund the completion of the Company’s Phase 3 clinical trial as currently contemplated with its product candidate CPP-1X/sul for the treatment of familial adenomatous polyposis (the “Phase 3 Trial”); provided that (a) this Section 4.4 shall not apply to any Investment in a Qualified Financing that is an IPO, and (b) the Company may use the net proceeds hereunder in its sole discretion in the event that either the Option and Collaboration Agreement or License Agreement is terminated or the Company’s Phase 3 Trial is terminated.

4.5 Indemnification of Purchaser. Subject to the provisions of this Section 4.5 and in consideration of the Purchaser’s execution of the Transaction Documents and acquiring the Securities, the Company will indemnify and hold the Purchaser and its directors, officers, shareholders, members, managers, 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, shareholders, agents, members, managers, 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 persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of: (a) any misrepresentation or breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents; or (b) any action instituted against any Purchaser Party in any capacity, or its Affiliates, by any stockholder of the Company who is neither an Affiliate of such Purchaser Party nor another Purchaser Party, with respect to (x) any of the transactions contemplated by the Transaction Documents; or (y) any transaction directly or indirectly financed with the proceeds of the issuance of the Securities (unless such action is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing; (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel; or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by the Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.5 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law.

4.6 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon request of the Purchaser. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchaser at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of the Purchaser.

Restrictions on Sale. The Purchaser hereby agrees not to sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Securities or other securities of the Company held by the Purchaser during the 180-day period following the effective date of the registration statement for the Company’s IPO (or such other period as may be requested by the Company or an underwriter solely to accommodate regulatory restrictions on (i) the publication or other distribution of research reports; and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto)(the “Lock-Up Period”), provided, that all officers and directors of the Company and holders of at least 5% of the Company’s voting securities are bound by and have entered into similar agreements. The obligations described in this Section 4.7 shall not apply to a registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions and may stamp each certificate with a legend as substantially set forth in Section 4.1 with respect to the shares of the Securities (or other securities of the Company) subject to the foregoing restriction until the end of such 180-day (or other) period. The Purchaser agrees to execute a market stand-off agreement with the underwriters in the offering in customary form consistent with the provisions of this Section 4.7. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all holders subject to such agreements, pro rata based on the number of shares subject to such agreements.

4.7 Option and Investment. Notwithstanding anything in this Agreement to the contrary, if the Purchaser does not consummate the Investment in accordance with the terms of this Agreement (including the satisfaction of the conditions set forth in Section 2.7(b) above), then (a) such failure to purchase shall be a material breach of this Agreement, and (b) the Option described in Section 2.2 and the Option and Collaboration Agreement shall be null and void and not exercisable by the Purchaser.

ARTICLE V.

MISCELLANEOUS

5.1 Board Observer Rights. (a) Beginning on the date hereof until the date of exercise of the option in accordance with the terms of the Option and Collaboration Agreement or the expiration of the option period as set forth therein (the “Observer Period”), the Company agrees that it will invite one representative designated by the Purchaser (the “Observer”) to attend, in a non-voting observer capacity, all formal meetings of the Board of Directors in which a quorum is present for the purposes of permitting Observer to have current information with respect to the affairs of the Company and the actions taken by the Board of Directors (the “Approved Purposes”); provided that such Observer designated by the Purchaser is subject to the Company’s approval (which approval shall not be unreasonably withheld). In no event shall Observer: (i) be deemed to be a member of the Board of Directors; (ii) have the right to vote on any matter under consideration by the Board of Directors or otherwise have any power to cause the Company to take, or not to take, any action; or (iii) except as expressly set forth in this Section 5.1, have or be deemed to have, or otherwise be subject to, any duties (fiduciary or otherwise) to the Company or its stockholders or any duties (fiduciary or otherwise) otherwise applicable to the directors of the Company. As a non-voting observer, Observer will also be provided (concurrently with delivery to the directors of the Company and in the same manner delivery is made to them) copies of all notices, minutes, consents, and all other materials or information (financial or otherwise) that are provided to the directors with respect to a meeting or any written consent in lieu of meeting (except to the extent Observer has been excluded therefrom pursuant to clause (d) below).

(c) If a meeting of the Board of Directors is conducted via telephone or other electronic medium (e.g., videoconference), Observer may attend such meeting via the same medium; provided, however, that Observer shall not provide any other person access to such meeting without the Company’s express prior written consent (which consent may be by e-mail).

(d) Notwithstanding the foregoing, the Company may exclude Observer from access to any material or meeting or portion thereof if: (i) the Board of Directors concludes in good faith, upon advice of the Company’s counsel, that such exclusion is reasonably necessary to preserve the attorney-client privilege between the Company and such counselor or if the Company in good faith believes that the Observer has a potential conflict of interest; provided, however, that any such exclusion shall apply only to such portion of the material or such portion of the meeting which would be required to preserve such privilege and not to any other portion thereof; or (ii) such portion of a meeting is an executive session limited solely to independent director members of the Board of Directors, independent auditors and/or legal counsel, as the Board of Directors may designate, and Observer (assuming Observer were a member of the Board of Directors) would not meet the then-applicable standards for independence adopted by the New York Stock Exchange, or such other exchange on which the Company’s securities are then traded.

(e) The Observer shall not receive compensation from the Company for the performance of as an Observer; however, the Company shall reimburse Observer for all reasonable out-of-pocket expenses incurred by Observer in connection with attendance at Board of Directors meetings. All reimbursements payable by the Company pursuant to this Section 5.1(d) shall be paid to Observer in accordance with the Company’s policies and practices with respect to director expense reimbursement then in effect

(f) The rights described in this Section 5.1 shall terminate upon: (i) the end of the Observer Period; (ii) any material violation of the terms of this Section 5.1 by Observer that (A) remains uncured within ten (10) business days after receipt of notice thereof, or (B) if such violation is not subject to cure, directly causes material harm to the Company in the Board of Directors’ sole and absolute discretion.

(g) In consideration of the Company’s disclosure to Observer of information that is not publicly available concerning the Company for the Approved Purposes, Purchaser agrees that this Section 5.1 will apply to all information, in any form whatsoever, disclosed or made available to Observer concerning the Company, its affiliates and/or the Approved Purposes (“Confidential Information”).

(h) Except as otherwise provided herein, Purchaser agrees: (i) to hold Confidential Information in strict confidence; (ii) not to disclose Confidential Information to any third parties; and (iii) not to use any Confidential Information for any purpose except for the Approved Purposes. Observer may disclose the Confidential Information to its responsible agents, advisors, affiliates and representatives with a bona fide need to know (“Representatives”), but only to the extent necessary for the Approved Purposes. Purchaser agrees that Observer shall instruct all such Representatives not to disclose such Confidential Information to third parties without the prior written permission of the Company. Purchaser will, at all times, remain liable under the terms of this Agreement for any unauthorized disclosure or use by Observer or any Representatives of Confidential Information provided to such Representatives by Observer.

(i) The foregoing restriction on the use and nondisclosure of Confidential Information will not include information which, as evidenced by written documentation: (i) is, or hereafter becomes, through no act or failure to act on the part of Observer, generally known or available to the public; (ii) was acquired by Observer before receiving such information from the Company, without restriction as to use or disclosure; (iii) is hereafter furnished to Observer by a third party, without, to Observer’s knowledge, restriction as to use or disclosure; (iv) such information was independently developed by Observer; or (v) is required or requested to be disclosed pursuant to judicial, regulatory or administrative process or court order, provided, that to the extent permitted by law, rule or regulation and reasonably practicable under the circumstances, Observer gives the Company prompt notice of such required disclosure so that the Company may challenge the same

(j) Following the termination of the rights of Observer described in this Section 5.1 and upon request of the Company, Observer will promptly: (i) return to the Company all physical materials containing or consisting of Confidential Information and all hard copies thereof; and (ii) destroy all electronically stored Confidential Information in Observer’s possession or control. Observer may retain in his confidential files one copy of any item of Confidential Information in order to comply with any legal, compliance or regulatory requirements. Any Confidential Information that is not returned or destroyed, including, without limitation, any oral Confidential Information, and all notes, analyses, compilations, studies or other documents prepared by or for the benefit of Observer from such information, will remain subject to the confidentiality obligations set forth in this Agreement indefinitely.

(k) All Confidential Information is provided to Observer “as is” and the Company does not make any representation or warranty as to the accuracy or completeness of the Confidential Information or any component thereof. The Company will have no liability to Observer resulting from the reliance on the Confidential Information by Observer or any third party to whom such Confidential Information is disclosed.

(l) Purchaser acknowledges that all of the Confidential Information is owned solely by the Company (or its licensors) and that the unauthorized disclosure or use of such Confidential Information would cause irreparable harm and significant injury, the degree of which may be difficult to ascertain. Therefore, in the event of any breach of this Agreement, the Company is entitled to seek all forms of equitable relief (including an injunction and order for specific performance), in addition to all other remedies available at law or in equity.

(m) Purchaser agrees that the Confidential Information is given in confidence in accordance with the terms of this Agreement, and Purchaser and Observer will not take any action relating to the securities of the Company which would constitute xxxxxxx xxxxxxx, market manipulation, or any other violation of applicable securities law. Observer agrees to instruct all of its Representatives to whom it discloses Confidential Information that they may not take any action relating to the securities of the Company which would constitute xxxxxxx xxxxxxx, market manipulation, or any other violation of applicable securities law.

(n) Prior to the designation of any Observer, Purchaser agrees to cause Observer to execute and deliver to the Company a written acknowledgement of such Observer’s obligations under this Section 5.1.

Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action, suit or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company under Section 4.5, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

5.10 Survival. The representations and warranties contained herein shall survive the Closings and the delivery of the Securities.

5.11 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 each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

5.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

5.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

5.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Purchaser will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.15 Payment Set Aside. To the extent that the Company makes a payment or payments to the Purchaser pursuant to any Transaction Document or the Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently set aside, recovered from, disgorged by or refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

5.16 Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plea or in any manner whatsoever claim, and will resist any and all effort to be compelled to take the benefit or advantage of, usury law wherever enacted, now or at any time hereafter in force, in connection with any claim, action or proceeding that may be brought by the Purchaser in order to enforce any right or remedy under any Transaction Document. Notwithstanding any provision to the contrary contained in any Transaction Document, it is expressly agreed and provided that the total liability of the Company under the Transaction Documents for payments in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”), and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated with any other sums in the nature of interest that the Company may be obligated to pay under the Transaction Documents exceed such Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to the Transaction Documents is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum contract rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents from the effective date thereof forward, unless such application is precluded by applicable law. If under any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Company to the Purchaser with respect to indebtedness evidenced by the Transaction Documents, such excess shall be applied by the Purchaser to the unpaid principal balance of any such indebtedness or be refunded to the Company, the manner of handling such excess to be at the Purchaser’s election.

5.17 Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

5.18 Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.

5.19 WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
