 Exhibit 10.1 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (the “Agreement”), dated as of
                     , 20         , between Salarius
Pharmaceuticals, Inc., a Delaware corporation (the “Company”), and                  (“Indemnitee”). 

W I T N E S S E T H: 
 WHEREAS,
Indemnitee is either a member of the Board of Directors of the Company (the “Board of Directors”) or an officer of the Company, or both, and in such capacity or capacities, or otherwise as an Agent (as hereinafter defined) of the
Company, is performing a valuable service for the Company; and 
 WHEREAS, the Company is aware that competent and experienced persons are
increasingly reluctant to serve as directors or officers of corporations or other business entities unless they are protected by comprehensive indemnification and liability insurance, due to increased exposure to litigation costs and risks resulting
from their service to such corporations, and because the exposure frequently bears no reasonable relationship to the compensation of such directors and officers; and 

WHEREAS, the Board of Directors of the Company has concluded that, to retain and attract talented and experienced individuals to serve or
continue to serve as officers or directors of the Company or as an Agent, and to encourage such individuals to take the business risks necessary for the success of the Company, it is necessary for the Company contractually to indemnify directors,
officers and Agents and to assume for itself to the fullest extent permitted by law expenses and damages in connection with claims against such officers, directors and Agents in connection with their service to the Company; and 

WHEREAS, Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”), under which the Company is
organized, empowers the Company to indemnify by agreement its officers, directors, employees and agents, and persons who serve, at the request of the Company, as directors, officers, employees or agents of other corporations or enterprises, and
expressly provides that the indemnification provided by the DGCL is not exclusive; and 
 WHEREAS, the Company desires and has requested the
Indemnitee to serve or continue to serve as a director, officer or Agent of the Company free from undue concern for claims for damages arising out of or related to such services to the Company; and 

WHEREAS, Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition
that he or she be indemnified as herein provided; and 
 WHEREAS, it is intended that Indemnitee shall be paid promptly by the Company all
amounts necessary to effectuate in full the indemnity provided herein; and 
 WHEREAS, certain defined terms are set forth in
Section 17 below: 












 NOW, THEREFORE, in consideration of the premises and the covenants in this Agreement, and of
Indemnitee serving or continuing to serve the Company as an Agent and intending to be legally bound hereby, the parties hereto agree as follows: 

1. Services by Indemnitee. Indemnitee agrees to serve or continue to serve (a) as a director or an officer of the Company, or both,
so long as Indemnitee is duly appointed or elected and qualified, and until such time as Indemnitee resigns or fails to stand for election or is removed from Indemnitee’s position in each case in accordance with the applicable provisions of the
Certificate of Incorporation and Bylaws of the Company, or (b) otherwise as an Agent of the Company. Indemnitee may from time to time also perform other services at the request or for the convenience of, or otherwise benefiting the Company or
any subsidiary of the Company. Indemnitee may at any time and for any reason resign or be removed from such position (subject to any other contractual obligation or other obligation imposed by operation of law), in which event the Company shall have
no obligation under this Agreement to continue Indemnitee in any such position. 
 2. Indemnification of Indemnitee. Subject to the
limitations set forth herein and particularly in Section 6 hereof, the Company hereby agrees to indemnify Indemnitee as follows: 
 (a)
The Company shall, with respect to any Proceeding (as hereinafter defined), indemnify Indemnitee to the fullest extent permitted by applicable law or as such law may from time to time be amended (but, in the case of any such amendment, only to the
extent such amendment permits the Company to provide broader indemnification rights than the law permitted the Company to provide before such amendment). The right to indemnification conferred herein shall be presumed to have been relied upon by
Indemnitee in serving or continuing to serve the Company as an Agent and shall be enforceable as a contract right. Without in any way diminishing the scope of the indemnification provided by this Section 2(a), the rights of indemnification of
Indemnitee shall include but shall not be limited to those rights hereinafter set forth. 
 (b) The Company shall indemnify Indemnitee if
Indemnitee is or was a party or is threatened to be made a party to any Proceeding (other than an action by or in the right of the Company) by reason of the fact that Indemnitee is or was an Agent of the Company, or any subsidiary of the Company, or
by reason of the fact that Indemnitee is or was serving at the request of the Company as an Agent of another corporation, partnership, joint venture, trust or other enterprise, against Expenses (as hereinafter defined) or Liabilities (as hereinafter
defined), actually and reasonably incurred by Indemnitee in connection with such Proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful. 
 (c) The Company
shall indemnify Indemnitee if Indemnitee was or is a party or is threatened to be made a party to any Proceeding by or in the right of the Company or any subsidiary of the Company to procure a judgment in its favor by reason of the fact that
Indemnitee is or was an Agent of the Company, or any subsidiary of the Company, or by reason of the fact that Indemnitee is or was serving at the request of the Company as an Agent of another corporation, partnership, joint venture, trust or other
enterprise, against (i) Expenses and (ii) to the fullest extent permitted by law, Liabilities if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company,
except with respect to both clauses (i) and (ii) hereof, no indemnification shall be made in respect of any claim, issue or matter as to which Indemnitee shall have been adjudged to be liable to the Company unless and only to the extent that
the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly
and reasonably entitled to indemnity for such expenses which the Court of Chancery of the State of Delaware or such other court shall deem proper.

 3. Advancement of Expenses. All reasonable Expenses incurred by or on behalf of
Indemnitee (including costs of enforcement of this Agreement) shall be advanced from time to time by the Company to Indemnitee within thirty (30) days after the receipt by the Company of a written request for an advance of Expenses, whether
prior to or after final disposition of a Proceeding (except to the extent that there has been a Final Adverse Determination (as hereinafter defined) that Indemnitee is not entitled to be indemnified for such Expenses), including without limitation
any Proceeding brought by or in the right of the Company. The written request for an advancement of any and all Expenses under this paragraph shall contain reasonable detail of the Expenses incurred by Indemnitee. In the event that such written
request shall be accompanied by an affidavit of counsel to Indemnitee to the effect that such counsel has reviewed such Expenses and that such Expenses are reasonable in such counsel’s view, then such expenses shall be deemed reasonable in the
absence of clear and convincing evidence to the contrary. By execution of this Agreement, Indemnitee shall be deemed to have made whatever undertaking as may be required by law at the time of any advancement of Expenses with respect to repayment to
the Company of such Expenses. In the event that the Company shall breach its obligation to advance Expenses under this Section 3, the parties hereto agree that Indemnitee’s remedies available at law would not be adequate and that
Indemnitee would be entitled to specific performance. 
 4. Presumptions and Effect of Certain Proceedings. Upon making a request for
indemnification, Indemnitee shall be presumed to be entitled to indemnification under this Agreement and the Company shall have the burden of proof to overcome that presumption in reaching any contrary determination. The termination of any
Proceeding by judgment, order, settlement, arbitration award or conviction, or upon a plea of nolo contendere or its equivalent shall not affect this presumption or, except as determined by a judgment or other final adjudication adverse to
Indemnitee, establish a presumption regarding any factual matter relevant to determining Indemnitee’s rights to indemnification hereunder. If the person or persons so empowered to make a determination pursuant to Section 5 hereof shall
have failed to make the requested determination within the period provided for in Section 5 hereof, a determination that Indemnitee is entitled to indemnification shall be deemed to have been made. 

5. Procedure for Determination of Entitlement to Indemnification. 

(a) Whenever Indemnitee believes that Indemnitee is entitled to indemnification pursuant to this Agreement, Indemnitee shall submit a written
request for indemnification to the Company. Any request for indemnification shall include sufficient documentation or information reasonably available to Indemnitee for the determination of entitlement to indemnification. In any event, Indemnitee
shall submit Indemnitee’s claim for indemnification within a reasonable time, not to exceed five (5) years after any judgment, order, settlement, dismissal, arbitration award, conviction, acceptance of a plea of nolo contendere or its
equivalent, or final determination, whichever is the later date for which Indemnitee requests indemnification. The Secretary or other appropriate officer shall, promptly upon receipt of Indemnitee’s request for indemnification, advise the Board
of Directors in writing that Indemnitee has made such request. Determination of Indemnitee’s entitlement to indemnification shall be made not later than sixty (60) days after the Company’s receipt of Indemnitee’s written request
for such indemnification, provided that any request for indemnification for Liabilities, other than amounts paid in settlement, shall have been made after a determination thereof in a Proceeding. If it is so determined that the Indemnitee is
entitled to indemnification, and Indemnitee has already paid the Liabilities, reimbursement to the Indemnitee shall be made within ten (10) days after such determination; otherwise, the Company shall pay the Liabilities on behalf of the
Indemnitee if and when the Indemnitee becomes legally obligated to make payment. 
 (b) The Company shall be entitled to select the forum in
which Indemnitee’s entitlement to indemnification will be heard; provided, however, that if there is a Change in Control of the Company, Independent Legal Counsel (as hereinafter defined) shall determine whether Indemnitee is entitled to
indemnification. The forum shall be any one of the following: 
 (i) a majority vote of Disinterested Directors (as
hereinafter defined), even though less than a quorum; 
 (ii) by a committee of Disinterested Directors designated by
majority vote of Disinterested Directors, even though less than a quorum; 

  
 3 













 (iii) Independent Legal Counsel, whose determination shall be made in a
written opinion; or 
 (iv) the stockholders of the Company. 

6. Specific Limitations on Indemnification. Notwithstanding anything in this Agreement to the contrary, the Company shall not be
obligated under this Agreement to make any payment to Indemnitee with respect to any Proceeding (and Indemnitee hereby waives and relinquishes any right under this Agreement, the Certificate of Incorporation, the Bylaws or otherwise to be
indemnified and held harmless or to receive any advancement of Expenses): 
 (a) Provided there has been no Change in Control, for
Liabilities in connection with Proceedings settled without the Company’s consent, which consent, however, shall not be unreasonably withheld; 

(b) For an accounting of profits made from the purchase or sale by Indemnitee of securities of the Company within the meaning of section 16(b)
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or similar provisions of any state statutory or common law; 

(c) To the extent it would be otherwise prohibited by law; or 

(d) In connection with a Proceeding commenced by Indemnitee (other than a Proceeding commenced by Indemnitee to enforce Indemnitee’s
rights under this Agreement) unless the commencement of such Proceeding was authorized by the Board of Directors. 
 7. Fees and Expenses
of Independent Legal Counsel. The Company agrees to pay the reasonable fees and expenses of Independent Legal Counsel should such Independent Legal Counsel be retained to make a determination of Indemnitee’s entitlement to indemnification
pursuant to Section 5(b) of this Agreement, and to fully indemnify such Independent Legal Counsel against any and all expenses and losses incurred by any of them arising out of or relating to this Agreement or their engagement pursuant hereto.

 8. Remedies of Indemnitee. 

(a) In the event that (i) a determination pursuant to Section 5 hereof is made that Indemnitee is not entitled to indemnification,
(ii) advances of Expenses are not made pursuant to this Agreement, (iii) payment has not been timely made following a determination of entitlement to indemnification pursuant to this Agreement, or (iv) Indemnitee otherwise seeks
enforcement of this Agreement, Indemnitee shall be entitled to a final adjudication in the Court of Chancery of the State of Delaware of the remedy sought. Alternatively, unless court approval is required by law for the indemnification sought by
Indemnitee, Indemnitee at Indemnitee’s option may seek an award in arbitration to be conducted by a single arbitrator in accordance with JAMS’ Comprehensive Arbitration Rules and Procedures then in effect, which award is to be made within
ninety (90) days following the filing of the demand for arbitration. The Company shall not oppose Indemnitee’s right to seek any such adjudication or arbitration award. In any such proceeding or arbitration Indemnitee shall be presumed to
be entitled to indemnification and advancement of Expenses under this Agreement and the Company shall have the burden of proof to overcome that presumption. 

  
 4 













 (b) In the event that a determination that Indemnitee is not entitled to indemnification, in
whole or in part, has been made pursuant to Section 5 hereof, the decision in the judicial proceeding or arbitration provided in paragraph (a) of this Section 8 shall be made de novo and Indemnitee shall not be prejudiced by
reason of a determination that Indemnitee is not entitled to indemnification. 
 (c) If a determination that Indemnitee is entitled to
indemnification has been made pursuant to Section 5 hereof, or is deemed to have been made pursuant to Section 4 hereof or otherwise pursuant to the terms of this Agreement, the Company shall be bound by such determination. 

(d) The Company shall be precluded from asserting that the procedures and presumptions of this Agreement are not valid, binding and
enforceable. The Company shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement and is precluded from making any assertion to the contrary. 

(e) Expenses reasonably incurred by Indemnitee in connection with Indemnitee’s request for indemnification under, seeking enforcement of
or to recover damages for breach of this Agreement shall be advanced by the Company when and as incurred by Indemnitee irrespective of any Final Adverse Determination that Indemnitee is not entitled to indemnification. 

9. Contribution. To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is
unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in
settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect
(i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and
agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 10. Maintenance of Insurance. The Company represents
that it presently has in place certain directors’ and officers’ liability insurance policies covering its directors and officers. Subject only to the provisions within this Section 10, the Company agrees that so long as Indemnitee
shall have consented to serve or shall continue to serve as a director or officer of the Company, or both, or as an Agent of the Company, and thereafter so long as Indemnitee shall be subject to any possible Proceeding (such periods being
hereinafter sometimes referred to as the “Indemnification Period”), the Company will use all reasonable efforts to maintain in effect for the benefit of Indemnitee one or more valid, binding and enforceable policies of
directors’ and officers’ liability insurance from established and reputable insurers, providing, in all material respects, coverage both in scope and amount which are substantially similar to that presently provided or, following the
Company’s initial public offering, than that provided as of the time of such initial public offering. 
 Anything in this Agreement to
the contrary notwithstanding, to the extent that and for so long as the Company shall choose to continue to maintain any policies of directors’ and officers’ liability insurance during the Indemnification Period, the Company shall maintain
similar and equivalent insurance for the benefit of Indemnitee during the Indemnification Period (unless such insurance shall be less favorable to Indemnitee than the Company’s existing policies). 

  
 5 













 11. Modification, Waiver, Termination and Cancellation. No supplement, modification,
termination, cancellation or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. 
 12. Subrogation. In the event of
payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights,
including the execution of such documents necessary to enable the Company effectively to bring suit to enforce such rights. 
 13. Notice
by Indemnitee and Defense of Claim. Indemnitee shall promptly notify the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any matter, whether civil,
criminal, administrative or investigative that may result in the right to indemnification or the advancement of Expenses, but the omission so to notify the Company will not relieve it from any liability that it may have to Indemnitee if such
omission does not prejudice the Company’s rights. If such omission does prejudice the Company’s rights, the Company will be relieved from liability only to the extent of such prejudice. Notwithstanding the foregoing, such omission will not
relieve the Company from any liability that it may have to Indemnitee otherwise than under this Agreement. With respect to any Proceeding as to which Indemnitee notifies the Company of the commencement thereof: 

(a) The Company will be entitled to participate therein at its own expense; and 

(b) The Company jointly with any other indemnifying party similarly notified will be entitled to assume the defense thereof, with counsel
reasonably satisfactory to Indemnitee; provided, however, that the Company shall not be entitled to assume the defense of any Proceeding if there has been a Change in Control or if Indemnitee shall have reasonably concluded that there may be a
conflict of interest between the Company and Indemnitee with respect to such Proceeding. After notice from the Company to Indemnitee of its election to assume the defense thereof, the Company will not be liable to Indemnitee under this Agreement for
any Expenses subsequently incurred by Indemnitee in connection with the defense thereof, other than reasonable costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ Indemnitee’s own counsel in such
Proceeding, but the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defense thereof shall be at the expense of Indemnitee unless: 

(i) the employment of counsel by Indemnitee has been authorized by the Company; 

(ii) Indemnitee shall have reasonably concluded that counsel engaged by the Company may not adequately represent Indemnitee due
to, among other things, actual or potential differing interests; or 
 (iii) the Company shall not in fact have employed
counsel to assume the defense in such Proceeding or shall not in fact have assumed such defense and be acting in connection therewith with reasonable diligence; in each of which cases the fees and expenses of such counsel shall be at the expense of
the Company. 
 (c) The Company shall not settle any Proceeding in any manner that would impose any penalty or limitation on Indemnitee
without Indemnitee’s written consent; provided, however, that Indemnitee will not unreasonably withhold his or her consent to any proposed settlement.

 14. Notices. All notices, requests, demands and other communications hereunder shall
be in writing and shall be deemed to have been duly given if (i) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, or (ii) mailed by certified or registered mail with
postage prepaid, on the third business day after the date on which it is so mailed: 
  

	 	(a)	 If to Indemnitee, to the address set forth below Indemnitee’s signature on the signature page hereof.



  

	 	(b)	 If to the Company, to: 



Salarius Pharmaceuticals, Inc. 

2450 Holcombe Blvd. 
 Suite J-608 
 Houston, Texas 77021 

or to such other address as may have been furnished to Indemnitee by the Company or to the Company by Indemnitee, as the case may be. 

15. Nonexclusivity. The rights of Indemnitee hereunder shall not be deemed exclusive of any other rights to which Indemnitee may be
entitled under applicable law, the Company’s Certificate of Incorporation or Bylaws, or any agreements, vote of stockholders, resolution of the Board of Directors or otherwise, and to the extent that during the Indemnification Period the rights
of the then existing directors and officers are more favorable to such directors or officers than the rights currently provided to Indemnitee thereunder or under this Agreement, Indemnitee shall be entitled to the full benefits of such more
favorable rights. 
 16. Indemnification and Advancement Rights Primary. The Company hereby acknowledges that Indemnitee has or may
have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more parties other than the Company or an affiliate of the Company (collectively, the “Secondary Indemnitors”). The Company hereby
acknowledges and the Company and Indemnitee hereby agree that: (i) the Company is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Secondary Indemnitors to advance expenses or to provide
indemnification for the same expenses or liabilities incurred by Indemnitee are secondary); (ii) the Company shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all expenses,
judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation and/or Bylaws of the Company (or any other agreement between the Company
and Indemnitee), without regard to any rights Indemnitee may have against the Secondary Indemnitors; and (iii) the Company irrevocably waives, relinquishes and releases the Secondary Indemnitors from any and all claims against the Secondary
Indemnitors that the Company may have for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Secondary Indemnitors on behalf of Indemnitee with respect to
any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Secondary Indemnitors shall have a right of contribution and/or subrogation to the extent of such advancement or payment to all of the
rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Secondary Indemnitors are express third party beneficiaries of the terms of this provision.

of the election or nomination and directors whose election or nomination was previously so approved; 
 (iv) The stockholders
of the Company approve a merger or consolidation of the Company with any other Company, if such merger or consolidation would result in the voting securities of the Company outstanding immediately prior thereto representing (either by remaining

consolidation; or 
 (v) The stockholders of the Company approve (A) a plan of complete liquidation of the Company or
(B) an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets. 
 For purposes
of Subsections (i) and (ii) above, the term “person” shall have the same meaning as when used in sections 13(d) and 14(d) of the Exchange Act, but shall exclude (x) a trustee or other fiduciary holding securities

stock of the Company.

 8 













 Any other provision of this Section 17(b) notwithstanding, the term “Change in
Control” shall not include a transaction, if undertaken at the election of the Company, the result of which is to sell all or substantially all of the assets of the Company to another corporation (the “Surviving Company”);
provided that the Surviving Company is owned directly or indirectly by the stockholders of the Company immediately following such transaction in substantially the same proportions as their ownership of the Company’s common stock immediately
preceding such transaction; and provided, further, that the Surviving Company expressly assumes this Agreement. 
 (c) “Disinterested
Director” shall mean a director of the Company who is not or was not a party to the Proceeding in respect of which indemnification is being sought by Indemnitee. 

(d) “Expenses” shall include all direct and indirect costs (including, without limitation, attorneys’ fees, retainers,

include any Liabilities. 
 (e) “Final Adverse Determination” shall mean that a determination that Indemnitee is not
entitled to indemnification shall have been made pursuant to Section 5 hereof and either (1) a final adjudication in the courts of the State of Delaware from which there is no further right of appeal or decision of an arbitrator pursuant
to Section 8(a) hereof shall have denied Indemnitee’s right to indemnification hereunder, or (2) Indemnitee shall have failed to file a complaint in a Delaware court or seek an arbitrator’s award pursuant to Section 8(a) for
a period of one hundred twenty (120) days after the determination made pursuant to Section 5 hereof. 
 (f) “Independent
Legal Counsel” shall mean a law firm or a member of a firm selected by the Company and approved by Indemnitee (which approval shall not be unreasonably withheld) or, if there has been a Change in Control, selected by Indemnitee and approved

Company of which Indemnitee was or is a director, officer, employee or agent, or any subsidiary or affiliate of such a corporation, in any material matter, or (ii) any other party to the Proceeding giving rise to a claim for indemnification
hereunder. Notwithstanding the foregoing, the term “Independent Legal Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing
either the Company or Indemnitee in an action to determine Indemnitee’s right to indemnification under this Agreement. 
 (g)
“Liabilities” shall mean liabilities of any type whatsoever including, but not limited to, any judgments, fines, Employee Retirement Income Security Act excise taxes and penalties, penalties and amounts paid in settlement (including

(h) “Proceeding” shall mean any threatened, pending or completed action, claim, suit, arbitration, alternate dispute
resolution mechanism, investigation, administrative hearing or any other proceeding whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party, as a witness or otherwise, that is associated
with Indemnitee’s being an Agent of the Company.

Agreement, the Company and Indemnitee each irrevocably consent to the jurisdiction of the courts of the State of Delaware for all purposes in connection with any action or proceeding that arises out of or relates to this Agreement and agree that any
action instituted under this Agreement shall be brought only in the state courts of the State of Delaware. 
 22. Entire Agreement.

referred to herein or as provided in Section 15 hereof. 
 23. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement.
