SEPARATION AGREEMENT 

AND GENERAL RELEASE 

This Separation Agreement and General Release (“Agreement”) is entered into effective as of the 21st day of April, 2010, by and
between Paul T. Brady (“Executive”) and KV Pharmaceutical Company, a Delaware corporation (the “Company” or “KV”, and, together with Executive, the “Parties”). 

RECITALS 
 WHEREAS,
Executive has been employed by the Company as Vice President, Business Development and President of Particle Dynamics, Inc. (“PDI’); 

WHEREAS, KV is currently negotiating an asset purchase transaction (“Transaction”) wherein the assets of PDI will be
acquired by Edgewater Capital Partners, II L.P. (“Edgewater”); 
 WHEREAS, In connection with the Transaction,
Edgewater , which will be assuming the assets of PDI, would like Executive to serve as the Chief Executive Officer of PDI. Executive is willing to serve in such capacity; and Company understands and agrees that Executive will be serving as CEO of
PDI. 
 WHEREAS, The Company in part is entering into this Agreement in recognition of the positive contributions made by
Executive to the Company; 
 NOW THEREFORE, in consideration of the promises and mutual covenants contained herein, and
for other good and valuable consideration, the receipt and sufficiency of which are expressly acknowledged, the Parties agree and promise as follows: 
  

	1.	TERMINATION. Executive’s Resignation is effective as of the date the Transaction closes (the “Separation Date”). 

 

	2.	PAYMENTS. 

  

	 	a.	The Company shall immediately pay to Executive an amount equal to accrued but unpaid vacation pay due on the Separation Date. At the same time, or as soon as
practicable thereafter, the Company shall pay to Executive an amount equal to any unpaid expense reimbursements due to Executive (subject, however, to Executive’s obligation to provide adequate documentation of such expenses in the normal
course). All of Executive’s expenses were submitted current through the Separation date. 

  

	 	b.	With respect to any benefits or rights that Executive has accrued or earned under any of the Company’s employee benefit plans as of the Separation Date, Executive
shall be entitled to such benefits pursuant to the terms of such plans. 

  

 1 

	3.	TERMINATION BENEFITS. Subject to Executive abiding by the terms of this Agreement, his satisfactory transition of non-PDI responsibilities to other KV employees
which has been agreed to by the CEO, and in consideration of Executive’s release of claims and Executive’s other covenants and agreements contained herein, Executive shall be entitled to the following benefits: 

 

	 	a.	In the event the Transaction closes by May 30, 2010, the Company shall pay Executive a bonus equal to 26 weeks of his final annual salary, payable in two equal
installments. The initial installment shall be paid on the Separation Date and the second installment shall be paid on the date six months following the Separation Date. In addition, Executive shall be paid 26 weeks of his final annual salary on
KV’s regularly scheduled paydays in accordance with KV’s regular pay practice which are that Executive will be paid every two weeks for 26 weeks. 

 

	 	b.	 The Company shall pay Executive the additional sum of Forty Thousand Dollars ($40,000.00), representing the Retention Bonus to which Executive would
have become entitled had his employment continued. It shall be payable on
30th day of June 2010, and upon the condition that the
Executive satisfactorily performs his duties until the Separation Date; the approval for payment of this sum shall not be unreasonably withheld; 

  

	 	c.	Except as set forth in this Agreement, and with respect to any benefits or rights under any of the Company’s “employee benefit plans” within the meaning
of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), Executive acknowledges and agrees that he is not entitled to receive any other compensation or benefits of any sort from the Company or any
of its plans, direct or indirect subsidiaries, or other entities controlled by the Company, including, without limitation, salary, vacation, bonuses, annual incentives, stock options, short-term or long-term disability benefits.

  

	4.	SETTLEMENT OF EQUITY BASED AWARDS. Executive waives any and all right to unvested stock options held by Executive immediately prior to the Separation Date. In
lieu thereof Executive shall, on the first anniversary of the Separation Date, receive a payment of $50,000 (“Initial Payment”) plus an additional payment (the “Gross-Up Payment”) in an amount such that after payment by Executive
of all taxes, including federal, state, local, foreign and employment taxes, (collectively the “Taxes”) imposed on the Initial Payment and Gross-Up Payment, the Executive retains an amount equal to the Initial Payment. The Gross-Up Payment
shall be made at the same time as the Initial Payment, and the amount of applicable Taxes shall be based on the assumption that Executive pays taxes at the highest applicable marginal rate, and shall not be later adjusted. The determination of the
Company as to the amount of the Gross-Up Payment shall be final and conclusive and binding on the Executive and his beneficiaries, successors and assigns. 

  

	5.	INDEMNIFICATION. The Company agrees to indemnify Executive in accordance with the Bylaws in effect at the time of the request for indemnification.

  

	6.	COMPLETE RELEASE. The Parties intend to release and discharge each other from any and all claims they have or may have one against the other, and that such
releases and discharges extend to themselves and to the Released Parties, as defined below. Therefore, the Parties agree:

Company may not be aware. It is further understood and agreed that both Executive and Company are waiving all rights under any statute or common law principle which otherwise limit application of a general release to claims which the releasing party
does not know or suspect to exist in his favor at the time of signing the release which, if known by him, would have materially affected his settlement with the party being released/releasee. 

 

	 	f.	Neither the Executive nor the Company, nor his or its respective heirs, successors, agents, representatives or attorneys has filed or caused to be filed any lawsuit,
complaint, or charge with respect to any claim that such party/entity is releasing in this Agreement. Except as prohibited by law or public policy, each party promises never (i) to file or prosecute a lawsuit or complaint based on the claims
released by it in this Agreement, or (ii) to seek any damages, remedies, or other relief for him or it by filing or prosecuting a claim or charge with any administrative, judicial, or other governmental body, or in any arbitration proceeding
with respect to any claim released by such party/entity in this Agreement. Each Party hereto promises to request any governmental body or arbitration tribunal assuming jurisdiction of any such lawsuit, complaint, or charge to withdraw from the
matter or dismiss the matter against any and all Released Parties with prejudice against it. Neither the Executive nor the Company has assigned or transferred any claim that it is releasing, nor has such party/entity purported to do so.

  

 3 

	 	g.	Revocation Period. Executive acknowledges: (a) that Executive has hereby been advised in writing to consult with an attorney before signing this Release,
and (b) that Executive has had at least twenty-one (21) days after receipt of this Release to consider whether to accept or reject this Release. Executive understands that Executive may sign this Release prior to the end of such twenty-one
(21) day period, but is not required to do so. In addition, under ADEA, Executive has seven (7) days after Executive signs this Release to revoke it. Such revocation must be in writing and delivered either by hand or mailed and postmarked
within the seven (7) day period. If sent by mail, it is requested that it be sent by certified mail, return receipt. 

  

	7.	RETURN OF THE COMPANY’S DOCUMENTS AND PROPERTY. Executive agrees to return all records, documents, proposals, notes, lists, files, and any and all other
materials including, without limitation, computerized and/or electronic information (collectively, “Information”) that refers, relates or otherwise pertains to the Company and its affiliates, and/or their respective partners, principals,
officers, directors, stockholders, managers, employees, agents, representatives, or insurance companies, or their respective predecessors, successors or assigns at any time. In addition, Executive shall return to the Company all property or
equipment of the Company that he has been issued during the course of his employment or which he otherwise currently possesses. At Executive’s expense, Executive shall deliver to the Company at its St. Louis offices immediately following the

information described above. 

  

	8.	CONFIDENTIALITY; NON-DISPARAGEMENT. 

  

	 	a.	Executive acknowledges and agrees that he is subject to the terms and conditions of the “Confidential Information” and “Publication” and “Right
to Work Product” provisions set forth in Sections 6, 7, and 9 of the Employment Agreement and agrees to continue to be bound by those terms and conditions in accordance therewith. 

 

	 	b.	The parties agree that their professional and personal reputations are important and should not be impaired by either party after this Agreement is executed. Executive
therefore agrees to not make any oral or written communication to any person or entity which disparages, or has the effect of damaging the reputation of, or otherwise working in any way to the detriment of, the Company, its officers, shareholders,
directors, or management. The Company agrees that it will likewise not make any oral or written communication to any person or entity which disparages, or has the effect of damaging the reputation of, or otherwise working in any way to the detriment
of Executive’s professional or personal reputation. 

  

	 	c.	Nothing in this Section 8 shall prevent either Party from giving truthful testimony or information to law enforcement entities, administrative agencies or courts
or in any other legal proceedings as required by law, including, but not limited to, assisting in an investigation or proceeding brought by any governmental or regulatory body or official related to alleged violations of any law relating to fraud or
any rule or regulation of the Securities and Exchange Commission, or in asserting, enforcing, prosecuting or defending any rights or claims of Company or Executive under this Agreement or otherwise. 

 

 4 

	 	d.	Confidentiality. Executive and his attorneys agree that they will keep this Separation Agreement confidential, and will not disclose any of the terms of this
Separation Agreement, and any of the negotiations preceding or following it, to any third party, except (a) with the prior written consent of KV; (b) pursuant to an order or direction of court or agency or other governmental body having
jurisdiction to issue such order; (c) to tax advisors or accounting professionals themselves bound by ethical restraints of confidentiality; (d) to counsel for Executive, or (e) as may be necessary for the Parties to establish or
enforce rights under this agreement.

contained in the Employment Agreement and agrees to continue to be bound by those terms and conditions until 36 months after separationat which point Executive will be relieved of any and all Restrictive Covenants, including covenants to not
compete. However, if the Company fails to pay a timely monthly payment to Executive pursuant to this Agreement, then Executive shall be immediately released from any and all Restrictive Covenants, including covenants not to compete.

  

	10.	COOPERATION BY EXECUTIVE. Executive will cooperate in all reasonable respects with the Company and its affiliates in connection with any and all existing or
future litigation, actions, investigations or proceedings (whether civil, criminal, administrative, regulatory or otherwise) brought by or against the Company or any of its affiliates or otherwise, to the extent the Company reasonably deems
Executive’s cooperation necessary. Executive shall be promptly reimbursed for all reasonable out-of-pocket expenses incurred by him as a result of such cooperation, including, without limitation, his attorneys’ fees and expenses.

  

	11.	NON-ADMISSION OF LIABILITY. Nothing in this Agreement shall be construed as an admission of liability by Executive, any member of the Company or any of the
Released Parties; rather, Executive, the Company and the Released Parties are resolving all matters arising out of their employer-employee relationship and all other relationships between them as to which the Released Parties and the Company and
Executive each deny any liability. 

  

	12.	NECESSARY ACTIONS. The parties will take or cause to be taken such actions as are necessary to authorize, approve and take and/or carry out the actions
contemplated by this Agreement. 

  

	13.	BINDING EFFECT. This Agreement shall be binding upon and inure to the benefit of the Parties, and their respective heirs, administrators, representatives,
executors, attorneys, successors and assigns. 

  

	14.	SEVERABILITY. While the provisions contained in this Agreement are considered by the Parties to be reasonable in all circumstances, it is recognized that some
provisions may fail for technical reasons. Accordingly, it is hereby agreed and declared that if any of such provisions shall, either by itself or themselves or taken with others, be adjudged to be invalid as exceeding what is reasonable in all
circumstances for the protection of the interests of the Company, but would be valid if any particular restrictions or provisions were deleted or restricted or limited in a particular manner, then said provisions shall apply with any such deletions,
restrictions, limitations, reductions, curtailments, or modifications as may be necessary to make them valid and effective, and the remaining provisions shall be unaffected thereby, so long as both parties obtain the essential benefits of this
Agreement notwithstanding such deletions, restrictions, limitations, reductions, curtailments, or modifications. 

  

 5 

	15.	ENTIRE AGREEMENT; MODIFICATION. Except as set out herein, this Agreement constitutes the entire understanding among the Parties with respect to the matters set
forth herein. This Agreement supersedes all prior written and/or oral and all contemporaneous oral agreements, understandings and negotiations regarding the subject matter hereof. 

 

	16.	INTERPRETATION; GOVERNING LAW. This Agreement shall be construed as a whole according to its fair meaning and shall not be construed strictly for or against
either Party. Any uncertainty or ambiguity shall not be construed against the drafter. Captions are intended solely for convenience of reference and shall not be used in the interpretation of this Agreement. This Agreement shall be governed by and
construed and enforced pursuant to the laws of the State of Missouri applicable to contracts made and entirely to be performed therein without regard to rules relating to conflicts of law.

FORM OF COMMON STOCK 

WARRANT AGREEMENT 

DATED AS OF              

 SUNESIS PHARMACEUTICALS, INC. 

FORM OF COMMON STOCK WARRANT AGREEMENT 

COMMON STOCK WARRANT AGREEMENT (this “Agreement”), dated as of
                     between Sunesis Pharmaceuticals, Inc. , a Delaware corporation (the “Company”) and
                    , a [corporation] [national banking association] organized and existing under the laws of
                     and having a corporate trust office
in                    , as warrant agent (the “Warrant Agent”). 

WHEREAS, the Company proposes to sell [if Warrants are sold with other securities—[title of such other
securities being offered] (the “Other Securities”) with] warrant certificates evidencing one or more warrants (the “Warrants” or, individually, a “Warrant”) representing the right to purchase Common
Stock of the Company, par value $0.0001 per share (the “Warrant Securities”), such warrant certificates and other warrant certificates issued pursuant to this Agreement being herein called the “Warrant Certificates”; and

 WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing so to
act, in connection with the issuance, registration, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the
terms and conditions on which they may be issued, registered, transferred, exchanged, exercised and replaced. 
 NOW
THEREFORE, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree as follows: 

ARTICLE 1 

ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT CERTIFICATES 

1.1 Issuance Of Warrants. [If Warrants alone—Upon issuance, each Warrant Certificate shall evidence
one or more Warrants.] [If Other Securities and Warrants—Warrant Certificates shall be [initially] issued in connection with the issuance of the Other Securities [but shall be separately transferable on and after
                     (the “Detachable Date”)] [and shall not be separately transferable] and each Warrant Certificate shall evidence
one or more Warrants.] Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein, to purchase one Warrant Security. [If Other Securities and Warrants—Warrant Certificates
shall be initially issued in units with the Other Securities and each Warrant Certificate included in such a unit shall evidence                     
Warrants for each [$                     principal amount]
[                     shares] of Other Securities included in such unit.]

1.2 Execution And Delivery Of Warrant Certificates. Each Warrant Certificate, whenever issued, shall be in registered
form substantially in the form set forth in Exhibit A hereto, shall be dated the date of its countersignature by the Warrant Agent and may have such letters, numbers, or other marks of identification or designation and such legends or
endorsements printed, lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Agreement, or
as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange on which the Warrants may be listed, or to conform to usage. The Warrant Certificates shall
be signed on behalf of the Company by any of its present or future chief executive officers, presidents, senior vice presidents, vice presidents, chief financial officers, chief legal officers, treasurers, assistant treasurers, controllers,
assistant controllers, secretaries or assistant secretaries under its corporate seal reproduced thereon. Such signatures may be manual or facsimile signatures of such authorized officers and may be imprinted or otherwise reproduced on the
Warrant Certificates. The seal of the Company may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates. 

No Warrant Certificate shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant
Certificate has been countersigned by the manual signature of the Warrant Agent. Such signature by the Warrant Agent upon any Warrant Certificate executed by the Company shall be conclusive evidence that the Warrant Certificate so countersigned
has been duly issued hereunder. 
 In case any officer of the Company who shall have signed any of the Warrant Certificates
either manually or by facsimile signature shall cease to be such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent, such Warrant Certificates may be countersigned and delivered
notwithstanding that the person who signed Warrant Certificates ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Warrant
Certificate, shall be the proper officers of the Company, although at the date of the execution of this Agreement any such person was not such officer. 

The term “holder” or “holder of a Warrant Certificate” as used herein shall mean any person in whose name at the time
any Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose [If Other Securities 

 
and Warrants are not immediately detachable—or upon the registration of the Other Securities prior to the Detachable Date. Prior to the Detachable Date, the Company will,
or will cause the registrar of the Other Securities to, make available at all times to the Warrant Agent such information as to holders of the Other Securities as may be necessary to keep the Warrant Agent’s records up to date]. 

1.3 Issuance Of Warrant Certificates. Warrant Certificates evidencing the right to purchase Warrant Securities may be
executed by the Company and delivered to the Warrant Agent upon the execution of this Warrant Agreement or from time to time thereafter. The Warrant Agent shall, upon receipt of Warrant Certificates duly executed on behalf of the Company,
countersign such Warrant Certificates and shall deliver such Warrant Certificates to or upon the order of the Company.

ARTICLE 2 

WARRANT PRICE, DURATION AND EXERCISE OF WARRANTS 

2.1 Warrant Price. During the period specified in Section 2.2, each Warrant shall, subject to the terms of this
Warrant Agreement and the applicable Warrant Certificate, entitle the holder thereof to purchase the number of Warrant Securities specified in the applicable Warrant Certificate at an exercise price of
$                     per Warrant Security, subject to adjustment upon the occurrence of certain events, as hereinafter provided. Such purchase
price per Warrant Security is referred to in this Agreement as the “Warrant Price.” 
 2.2 Duration Of
Warrants. Each Warrant may be exercised in whole or in part at any time, as specified herein, on or after [the date thereof]
[                    ] and at or before
[                    ] p.m.,
[                    ] time, on
[                    ] or such later date as the Company may designate by notice to the Warrant Agent and the holders of Warrant Certificates mailed
to their addresses as set forth in the record books of the Warrant Agent (the “Expiration Date”). Each Warrant not exercised at or before
[                    ] p.m.,
[                    ] time, on the Expiration Date shall become void, and all rights of the holder of the Warrant Certificate evidencing such
Warrant under this Agreement shall cease. 
 2.3 Exercise Of Warrants. 

(a) During the period specified in Section 2.2, the Warrants may be exercised to purchase a whole number of Warrant
Securities in registered form by providing certain information as set forth on the reverse side of the Warrant Certificate and by paying in full, in lawful money of the United States of America, [in cash or by certified check or official bank check
in New York Clearing House funds] [by bank wire transfer in immediately available funds] the Warrant Price for each Warrant Security with respect to which a Warrant is being exercised to the Warrant Agent at its corporate trust office, provided that
such exercise is subject to receipt within five business days of such payment by the Warrant Agent of the Warrant Certificate with the form of election to purchase Warrant Securities set forth on the reverse side of the Warrant Certificate properly
completed and duly executed. The date on which payment in full of the Warrant Price is received by the Warrant Agent shall, subject to receipt of the Warrant Certificate as aforesaid, be deemed to be the date on which the Warrant is exercised;
provided, however, that if, at the date of receipt of such Warrant Certificates and payment in full of the Warrant Price, the transfer books for the Warrant Securities purchasable upon the exercise of such Warrants shall be closed, no such receipt
of such Warrant Certificates and no such payment of such Warrant Price shall be effective to constitute the person so designated to be named as the holder of record of such Warrant Securities on such date, but shall be effective to constitute such
person as the holder of record of such Warrant Securities for all purposes at the opening of business on the next succeeding day on which the transfer books for the Warrant Securities purchasable upon the exercise of such Warrants shall be opened,
and the certificates for the Warrant Securities in respect of which such Warrants are then exercised shall be issuable as of the date on such next succeeding day on which the transfer books shall next be opened, and until such date the Company shall
be under no duty to deliver any certificate for such Warrant Securities. The Warrant Agent shall deposit all funds received by it in payment of the Warrant Price in an account of the Company maintained with it and shall advise the Company by
telephone at the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited to its account. The Warrant Agent shall promptly confirm such telephone advice to the Company in writing.

(b) The Warrant Agent shall, from time to time, as promptly as practicable, advise the Company of (i) the number of
Warrant Securities with respect to which Warrants were exercised, (ii) the instructions of each holder of the Warrant Certificates evidencing such Warrants with respect to delivery of the Warrant Securities to which such holder is entitled upon
such exercise, (iii) delivery of Warrant Certificates evidencing the balance, if any, of the Warrants for the remaining Warrant Securities after such exercise, and (iv) such other information as the Company shall reasonably require.

 (c) As soon as practicable after the exercise of any Warrant, the Company shall issue to or upon the order of the
holder of the Warrant Certificate evidencing such Warrant the Warrant Securities to which such holder is entitled, in fully registered form, registered in such name or names as may be directed by such holder. If fewer than all of the Warrants
evidenced by such Warrant Certificate are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign and deliver, a new Warrant Certificate evidencing Warrants for the number of Warrant Securities
remaining unexercised. 
 (d) The Company shall not be required to pay any stamp or other tax or other governmental
charge required to be paid in connection with any transfer involved in the issue of the Warrant Securities, and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Security until such
tax or other charge shall have been paid or it has been established to the Company’s satisfaction that no such tax or other charge is due. 

 (e) Prior to the issuance of any Warrants there shall have been reserved, and
the Company shall at all times through the Expiration Date keep reserved, out of its authorized but unissued Warrant Securities, a number of shares sufficient to provide for the exercise of the Warrants. 

ARTICLE 3 

OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT CERTIFICATES 

3.1 No Rights As Warrant Securityholder Conferred By Warrants Or Warrant Certificates. No Warrant Certificate or Warrant
evidenced thereby shall entitle the holder thereof to any of the rights of a holder of Warrant Securities, including, without limitation, the right to receive the payment of dividends or distributions, if any, on the Warrant Securities or to
exercise any voting rights, except to the extent expressly set forth in this Agreement or the applicable Warrant Certificate.

3.2 Lost, Stolen, Mutilated Or Destroyed Warrant Certificates. Upon receipt by the Warrant Agent of evidence reasonably
satisfactory to it and the Company of the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate and/or indemnity reasonably satisfactory to the Warrant Agent and the Company and, in the case of mutilation, upon
surrender of the mutilated Warrant Certificate to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a bona fide purchaser, the Company shall
execute, and an authorized officer of the Warrant Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, stolen, destroyed or mutilated Warrant Certificate, a new Warrant Certificate of the same tenor and evidencing
Warrants for a like number of Warrant Securities. Upon the issuance of any new Warrant Certificate under this Section 3.2, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant to this Section 3.2 in lieu of any
lost, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to
the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. The provisions of this Section 3.2 are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement of mutilated, lost, stolen or destroyed Warrant Certificates. 

3.3 Holder Of Warrant Certificate May Enforce Rights. Notwithstanding any of the provisions of this Agreement, any
holder of a Warrant Certificate, without the consent of the Warrant Agent, the holder of any Warrant Securities or the holder of any other Warrant Certificate, may, in such holder’s own behalf and for such holder’s own benefit, enforce,
and may institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such holder’s right to exercise the Warrants evidenced by such holder’s Warrant Certificate in the manner
provided in such holder’s Warrant Certificate and in this Agreement. 
 3.4 Adjustments. 

(a) In case the Company shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares,
the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced and the number of Warrant Securities purchasable under the Warrants shall be proportionately increased. Conversely, in case the outstanding
shares of Common Stock of the Company shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Securities purchasable under the
Warrants shall be proportionately decreased. 
 (b) If at any time or from time to time the holders of Common Stock
(or any shares of stock or other securities at the time receivable upon the exercise of the Warrants) shall have received or become entitled to receive, without payment therefore, 

(i) Common Stock or any shares of stock or other securities which are at any time directly or indirectly convertible into or
exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution; 

(ii) any cash paid or payable otherwise than as a cash dividend paid or payable out of the Company’s current or
retained earnings; 
 (iii) any evidence of the Company’s indebtedness or rights to subscribe for or purchase
the Company’s indebtedness; or 
 (iv) Common Stock or additional stock or other securities or property
(including cash) by way of spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement (other than shares of Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of
Section 3.4(a) above), then and in each such case, the holder of each Warrant shall, upon the exercise of the Warrant, be entitled to receive, in addition to the number of Warrant Securities receivable thereupon, and without payment of any
additional consideration therefore, the amount of stock and other securities and property (including cash and indebtedness or rights to subscribe for or purchase indebtedness) which such holder would

 
hold on the date of such exercise had he been the holder of record of such Warrant Securities as of the date on which holders of Common Stock received or became entitled to receive such shares or
all other additional stock and other securities and property. 
 (c) In case of (i) any reclassification,
capital reorganization, or change in the Common Stock of the Company (other than as a result of a subdivision, combination, or stock dividend provided for in Section 3.4(a) or Section 3.4(b) above), (ii) share exchange, merger or
similar transaction of the Company with or into another person or entity (other than a share exchange, merger or similar transaction in which the Company is the acquiring or surviving corporation and which does not result in any change in the Common
Stock other than the issuance of additional shares of Common Stock) or (iii) the sale, exchange, lease, transfer or other disposition of all or substantially all of the properties and assets of the Company as an entirety (in any such case, a
“Reorganization Event”), then, as a condition of such Reorganization Event, lawful provisions shall be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the holders of the
Warrants, so that the holders of the Warrants shall have the right at any time prior to the expiration of the Warrants to purchase, at a total price equal to that payable upon the exercise of the Warrants, the kind and amount of shares of stock and
other securities and property receivable in connection with such Reorganization Event by a holder of the same number of Warrant Securities as were purchasable by the holders of the Warrants immediately prior to such Reorganization Event. In any
such case appropriate provisions shall be made with respect to the rights and interests of the holders of the Warrants so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities and property
deliverable upon exercise the Warrants, and appropriate adjustments shall be made to the Warrant Price payable hereunder provided the aggregate purchase price shall remain the same. In the case of any transaction described in clauses
(ii) and (iii) above, the Company shall thereupon be relieved of any further obligation hereunder or under the Warrants, and the Company as the predecessor corporation may thereupon or at any time thereafter be dissolved, wound up or
liquidated. Such successor or assuming entity thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Warrants issuable hereunder which heretofore shall not have been signed by the
Company, and may execute and deliver securities in its own name, in fulfillment of its obligations to deliver Warrant Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same legal rank and
benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Warrants had been issued at the date of the execution hereof. In any case of any such
Reorganization Event, such changes in phraseology and form (but not in substance) may be made in the Warrants thereafter to be issued as may be appropriate. The Warrant Agent may receive a written opinion of legal counsel as conclusive evidence
that any such Reorganization Event complies with the provisions of this Section 3.4.
 (d) The Company may, at
its option, at any time until the Expiration Date, reduce the then current Warrant Price to any amount deemed appropriate by the Board of Directors of the Company for any period not exceeding twenty consecutive days (as evidenced in a resolution
adopted by such Board of Directors), but only upon giving the notices required by Section 3.5 at least ten days prior to taking such action. 

(e) Except as herein otherwise expressly provided, no adjustment in the Warrant Price shall be made by reason of the issuance
of shares of Common Stock, or securities convertible into or exchangeable for shares of Common Stock, or securities carrying the right to purchase any of the foregoing or for any other reason whatsoever. 

(f) No fractional Warrant Securities shall be issued upon the exercise of Warrants. If more than one Warrant shall be
exercised at one time by the same holder, the number of full Warrant Securities which shall be issuable upon such exercise shall be computed on the basis of the aggregate number of Warrant Securities purchased pursuant to the Warrants so
exercised. Instead of any fractional Warrant Security which would otherwise be issuable upon exercise of any Warrant, the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the last
reported sale price (or bid price if there were no sales) per Warrant Security, in either case as reported on the principal registered national securities exchange on which the Warrant Securities are listed or admitted to trading on the business day
that next precedes the day of exercise or, if the Warrant Securities are not then listed or admitted to trading on any registered national securities exchange, the average of the closing high bid and low asked prices as reported on the OTC Bulletin
Board Service (the “OTC Bulletin Board”) operated by the Financial Industry Regulatory Authority, Inc. (“FINRA”) or, if not available on the OTC Bulletin Board, then the average of the closing high bid and low asked
prices as reported on any other U.S. quotation medium or inter-dealer quotation system on such date, or if on any such date the Warrant Securities are not listed or admitted to trading on a registered national securities exchange, are not included
in the OTC Bulletin Board, and are not quoted on any other U.S. quotation medium or inter-dealer quotation system, an amount equal to the same fraction of the average of the closing bid and asked prices as furnished by any FINRA member firm selected
from time to time by the Company for that purpose at the close of business on the business day that next precedes the day of exercise. 

(g) Whenever the Warrant Price then in effect is adjusted as herein provided, the Company shall mail to each holder of the
Warrants at such holder’s address as it shall appear on the books of the Company a statement setting forth the adjusted Warrant Price then and thereafter effective under the provisions hereof, together with the facts, in reasonable detail, upon
which such adjustment is based.
 3.5 Notice To Warrantholders. In case the Company shall (a) effect any
dividend or distribution described in Section 3.4(b), (b) effect any Reorganization Event, (c) make any distribution on or in respect of the Common Stock in connection with the dissolution, liquidation or winding up of the Company, or
(d) reduce the then current Warrant Price pursuant to Section 3.4(d), then the Company shall mail to each holder of Warrants at such holder’s address as it shall appear on the books of the Warrant Agent, at least ten days prior to the
applicable date hereinafter specified, a notice stating (x) the record date for such dividend or distribution, or, if a record is not to be taken, the date as of which the holders of record of Common Stock that will be entitled to

 
such dividend or distribution are to be determined, (y) the date on which such Reorganization Event, dissolution, liquidation or winding up is expected to become effective, and the date as
of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such Reorganization Event, dissolution, liquidation or winding up, or
(z) the first date on which the then current Warrant Price shall be reduced pursuant to Section 3.4(d). No failure to mail such notice nor any defect therein or in the mailing thereof shall affect any such transaction or any
adjustment in the Warrant Price required by Section 3.4. 
 3.6 [If The Warrants Are Subject To Acceleration By The
Company, Insert—Acceleration Of Warrants By The Company. 
 (a) At any time on or after
                    , the Company shall have the right to accelerate any or all Warrants at any time by causing them to expire at the close of
business on the day next preceding a specified date (the “Acceleration Date”), if the Market Price (as hereinafter defined) of the Common Stock equals or exceeds      percent (    %) of the
then effective Warrant Price on any twenty Trading Days (as hereinafter defined) within a period of thirty consecutive Trading Days ending no more than five Trading Days prior to the date on which the Company gives notice to the Warrant Agent of its
election to accelerate the Warrants. 
 (b) “Market Price” for each Trading Day shall be, if the
Common Stock is listed or admitted to trading on any registered national securities exchange, the last reported sale price, regular way (or, if no such price is reported, the average of the reported closing bid and asked prices, regular way) of
Common Stock, in either case as reported on the principal registered national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on any registered national securities exchange, the
average of the closing high bid and low asked prices as reported on the OTC Bulletin Board operated by FINRA, or if not available on the OTC Bulletin Board, then the average of the closing high bid and low asked prices as reported on any other U.S.
quotation medium or inter-dealer quotation system, or if on any such date the shares of Common Stock are not listed or admitted to trading on a registered national securities exchange, are not included in the OTC Bulletin Board, and are not quoted
on any other U.S. quotation medium or inter-dealer quotation system, the average of the closing bid and asked prices as furnished by any FINRA member firm selected from time to time by the Company for that purpose. “Trading Day”
shall be each Monday through Friday, other than any day on which securities are not traded in the system or on the exchange that is the principal market for the Common Stock, as determined by the Board of Directors of the Company.

(c) In the event of an acceleration of less than all of the Warrants, the Warrant Agent shall select the Warrants to be
accelerated by lot, pro rata or in such other manner as it deems, in its discretion, to be fair and appropriate. 

(d) Notice of an acceleration specifying the Acceleration Date shall be sent by mail first class, postage prepaid, to each
registered holder of a Warrant Certificate representing a Warrant accelerated at such holder’s address appearing on the books of the Warrant Agent not more than sixty days nor less than thirty days before the Acceleration Date. Such notice
of an acceleration also shall be given no more than twenty days, and no less than ten days, prior to the mailing of notice to registered holders of Warrants pursuant to this Section 3.6, by publication at least once in a newspaper of general
circulation in the City of New York. 
 (e) Any Warrant accelerated may be exercised until
[                    ] p.m.,
[                    ] time, on the business day next preceding the Acceleration Date. The Warrant Price shall be payable as provided in
Section 2.] 
 ARTICLE 4 

EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES 

4.1 Exchange And Transfer Of Warrant Certificates. [If Other Securities with Warrants which are immediately
detachable—Upon] [If Other Securities with Warrants which are not immediately detachable—Prior to the Detachable Date, a Warrant Certificate may be exchanged or transferred only together with the Other Security to
which the Warrant Certificate was initially attached, and only for the purpose of effecting or in conjunction with an exchange or transfer of such Other Security. Prior to any Detachable Date, each transfer of the Other Security shall operate
also to transfer the related Warrant Certificates. After the Detachable Date, upon] surrender at the corporate trust office of the Warrant Agent, Warrant Certificates evidencing Warrants may be exchanged for Warrant Certificates in other
denominations evidencing such Warrants or the transfer thereof may be registered in whole or in part; provided that such other Warrant Certificates evidence Warrants for the same aggregate number of Warrant Securities as the Warrant Certificates so
surrendered. The Warrant Agent shall keep, at its corporate trust office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates and exchanges and transfers of outstanding Warrant
Certificates, upon surrender of the Warrant Certificates to the Warrant Agent at its corporate trust office for exchange or registration of transfer, properly endorsed or accompanied by appropriate instruments of registration of transfer and written
instructions for transfer, all in form satisfactory to the Company and the Warrant Agent. No service charge shall be made for any exchange or registration of transfer of Warrant Certificates, but the Company may require payment of a sum
sufficient to cover any stamp or other tax or other governmental charge that may be imposed in connection with any such exchange or registration of transfer. Whenever any Warrant Certificates are so surrendered for exchange or registration of
transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled thereto a Warrant Certificate or Warrant Certificates duly authorized and executed by the Company, as so
requested. The Warrant Agent shall not be required to effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate evidencing a Warrant for a fraction of a

 
Warrant Security or a number of Warrants for a whole number of Warrant Securities and a fraction of a Warrant Security. All Warrant Certificates issued upon any exchange or registration of
transfer of Warrant Certificates shall be the valid obligations of the Company, evidencing the same obligations and entitled to the same benefits under this Agreement as the Warrant Certificate surrendered for such exchange or registration of
transfer.
 4.2 Treatment Of Holders Of Warrant Certificates. [If Other Securities and Warrants are not
immediately detachable—Prior to the Detachable Date, the Company, the Warrant Agent and all other persons may treat the owner of the Other Security as the owner of the Warrant Certificates initially attached thereto for any purpose and
as the person entitled to exercise the rights represented by the Warrants evidenced by such Warrant Certificates, any notice to the contrary notwithstanding. After the Detachable Date and prior to due presentment of a Warrant Certificate for
registration of transfer, the] [The] Company, the Warrant Agent and all other persons may treat the registered holder of a Warrant Certificate as the absolute owner thereof for any purpose and as the person entitled to exercise the rights
represented by the Warrants evidenced thereby, any notice to the contrary notwithstanding. 
 4.3 Cancellation Of
Warrant Certificates. Any Warrant Certificate surrendered for exchange, registration of transfer or exercise of the Warrants evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent and all Warrant
Certificates surrendered or so delivered to the Warrant Agent shall be promptly canceled by the Warrant Agent and shall not be reissued and, except as expressly permitted by this Agreement, no Warrant Certificate shall be issued hereunder in
exchange therefor or in lieu thereof. 
 The Warrant Agent shall deliver to the Company from time to time or otherwise dispose
of canceled Warrant Certificates in a manner satisfactory to the Company. 
 ARTICLE 5

upon with the Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket expenses (including reasonable counsel fees) incurred without negligence, bad faith or willful misconduct by the
Warrant Agent in connection with the services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless against, any loss, liability or expense incurred without negligence, bad
faith or willful misconduct on the part of the Warrant Agent, arising out of or in connection with its acting as Warrant Agent hereunder, including the reasonable costs and expenses of defending against any claim of such liability.

(b) Agent For The Company. In acting under this Warrant Agreement and in connection with the Warrant Certificates, the
Warrant Agent is acting solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any of the holders of Warrant Certificates or beneficial owners of Warrants. 

(c) Counsel. The Warrant Agent may consult with counsel satisfactory to it, which may include counsel for the Company,
and the written advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with the advice of such counsel. 

(d) Documents. The Warrant Agent shall be protected and shall incur no liability for or in respect of any action taken
or omitted by it in reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other paper or document reasonably believed by it to be genuine and to have been presented or signed by the proper parties.

 (e) Certain Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner

transaction with the Company and may act on, or as depositary, trustee or agent for, any committee or body of holders of Warrant Securities or other obligations of the Company as freely as if it were not the Warrant Agent hereunder. Nothing in

interest on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates.

Warrant Certificates specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrant Certificates against the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action
hereunder which may tend to involve it in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it. The Warrant Agent shall not be accountable or under any duty or responsibility
for the use by the Company of any of the Warrant Certificates authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application by the Company of the proceeds of the Warrant
Certificates. The Warrant Agent shall have no duty or responsibility in case of any default by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in the case of the receipt of any
written demand from a holder of a Warrant Certificate with respect to such default, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or,
except as provided in Section 6.2 hereof, to make any demand upon the Company. 
 5.3 Resignation, Removal And
Appointment Of Successors.

Warrant Certificates, that there shall at all times be a Warrant Agent hereunder until all the Warrants have been exercised or are no longer exercisable. 

(b) The Warrant Agent may at any time resign as agent by giving written notice to the Company of such intention on its part,
specifying the date on which its desired resignation shall become effective; provided that such date shall not be less than three months after the date on which such notice is given unless the Company otherwise agrees. The Warrant Agent
hereunder may be removed at any time by the filing with it of an instrument in writing signed by or on behalf of the Company and specifying such removal and the intended date when it shall become effective. Such resignation or removal shall
take effect upon the appointment by the Company, as hereinafter provided, of a successor Warrant Agent (which shall be a bank or trust company authorized under the laws of the jurisdiction of its organization to exercise corporate trust powers) and
the acceptance of such appointment by such successor Warrant Agent. The obligation of the Company under Section 5.2(a) shall continue to the extent set forth therein notwithstanding the resignation or removal of the Warrant Agent.

 (c) In case at any time the Warrant Agent shall resign, or shall be removed, or shall become incapable of acting,
or shall be adjudged a bankrupt or insolvent, or shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter constituted, or under any other applicable Federal or state bankruptcy, insolvency or similar law or shall
consent to the appointment of or taking possession by a receiver, custodian, liquidator, assignee, trustee, sequestrator (or other similar official) of the Warrant Agent or its property or affairs, or shall make an assignment for the benefit of
creditors, or shall admit in writing its inability to pay its debts generally as they become due, or shall take corporate action in furtherance of any such action, or a decree or order for relief by a court having jurisdiction in the premises shall
have been entered in respect of the Warrant Agent in an involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or state bankruptcy, insolvency or similar law, or a decree or order by a
court having jurisdiction in the premises shall have been entered for the appointment of a receiver, custodian, liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant Agent or of its property or affairs, or any public

Agent hereunder.
 (d) Any successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its
predecessor and to the Company an instrument accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance, shall become vested with all the authority, rights, powers, trusts,
immunities, duties and obligations of such predecessor with like effect as if originally named as Warrant Agent hereunder, and such predecessor, upon payment of its charges and disbursements then unpaid, shall thereupon become obligated to transfer,
deliver and pay over, and such successor Warrant Agent shall be entitled to receive, all monies, securities and other property on deposit with or held by such predecessor, as Warrant Agent hereunder. 

(e) Any corporation into which the Warrant Agent hereunder may be merged or converted or any corporation with which the
Warrant Agent may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or
substantially all the assets and business of the Warrant Agent, provided that it shall be qualified as aforesaid, shall be the successor Warrant Agent under this Agreement without the execution or filing of any paper or any further act on the part
