	Recipient:	 	Desert
    Ventures Inc.

 

1.
Definitions. The terms defined in the instrument to which this Exhibit is attached and made part of shall have the same meanings
in this Exhibit. The following definitions shall apply to this Exhibit.

 

1.1
“Gross Returns” means all income and revenues accrued, received, and realized by Payor from the production of Minerals
and products of Minerals from the Property.

 

1.2
“Property” means the real property described in the instrument to which these Gross Returns provisions are attached
and made a part.

 

2.
Payment Procedures.

 

2.1
Accrual of Obligation. Payor’s obligation to pay the royalty shall accrue and become due and payable upon the sale or
shipment from the Property of unrefined metals, dore metal, concentrates, ores or other Minerals or Minerals products or, if refined
metals are produced, upon the outturn of refined metals meeting the requirements of the specified published price to Payor’s
account.

 

2.2
Futures or Forward Sales, Etc. Gross Returns shall be determined irrespective of any actual arrangements for the sale or other
disposition of Minerals by Payor, specifically including but not limited to forward sales, futures trading or commodities options
trading, and any other price hedging, price protection, and speculative arrangements that may involve the possible delivery of
gold, silver or other metals produced from Minerals.

 

2.3
Quarterly Calculations and Payments. The Royalty shall be determined on a quarterly basis. Payor shall pay Recipient each
quarterly royalty payment on or before the last business day of the quarter immediately following the quarter in which the royalty
payment obligation accrued. Payor acknowledges that late payment by Payor to Recipient of royalty payments will cause Recipient
to incur costs, the exact amount of which will be difficult to ascertain. Accordingly, if any amount due and payable by Payor
is not received by Recipient within ten (10) days after such amount is due, then Payor shall pay to Recipient a late charge equal
to ten percent (10%) of such overdue amount. Recipient’s acceptance of such late charge shall not constitute a waiver of
Payor’ default with respect to such overdue amount, nor prevent Recipient from exercising any of Recipient’s other
rights and remedies. If any amount payable by Payor remains delinquent for a period in excess of thirty (30) days, Payor shall
pay to Recipient, in addition to the late payment, interest from and after the due date at the statutory interest rate.

 

    	 	13	 

    	 

    

 

2.4
Statements. At the time of payment of the royalty, Payor shall accompany such payment with a statement which shows in detail
the quantities and grades of refined gold, silver or other metals or dore, concentrates or ores produced and sold or deemed sold
by Payor in the preceding quarter. Payor shall pay the Royalty by wire transfer to an account which Recipient designates.

 

2.5
Audit. Upon reasonable notice and at a reasonable time, the Recipient shall have the right to audit and examine the Payor’s
accounts and records relating to the calculation of the Gross Returns Royalty payments. If such audit determines that there has
been a deficiency or an excess in the payment made to Recipient, such deficiency or excess shall be resolved by adjusting the
next monthly royalty payment due Recipient. Recipient shall pay all costs of such audit unless a deficiency of three percent (3%)
or more of the royalty payment due for the calendar month in question is determined to exist. All books and records used by Payor
to calculate the Royalty payments shall be kept in accordance with generally accepted accounting principles applicable to the
mining industry.

 

2.6
Sampling and Commingling. Payor shall have the right to commingle Minerals and ores from the Property and materials from other
properties, provided, that Payor first informs Recipient, in writing, of Payor’s intention to commingle and delivers to
Recipient a detailed written description of Payor’s commingling plan. Recipient shall have ninety (90) days during which
to review, comment on and approve Payor’s proposed commingling plan. In any and all events, all Minerals and ores shall
be measured and sampled by Payor in accordance with sound mining and metallurgical practices for metal and mineral content before
commingling of any such Minerals or ores with materials from any other property. Representative samples of materials from the
Property intended to be commingled shall be retained by Payor, and assays of these samples shall be made before commingling to
determine the metal content of each ore. Detailed records shall be kept by Recipient showing measurements, assays of metal content
and gross metal content of the materials from the Property are commingled. Payor shall prepare and maintain records of the production
of Minerals from the Property, assays of samples taken from the Property and all other records reasonably necessary to accurately
account for the production of Minerals from the Property.

 

2.7
Royalty as Burden on the Property. The Royalty shall be a burden on, an interest in, and a covenant which runs with the Property.
The Royalty shall be prior and superior to any interest in the Property or the Agreement of which this Net Smelter Return provision
is a part which Payor grants to any third party. Payor agrees and covenants that at Recipient’s request, Payor, Recipient,
and Payor’s refiner or smelter shall enter into an agreement pursuant to which the Royalty shall be deposited or paid directly
to an account in Recipient’s name with the refiner or smelter.

AGENT
 FORM OF COMMON STOCK

WARRANT AGREEMENT
 DATED
AS OF                      

 SUNESIS PHARMACEUTICALS, INC. 

FORM OF COMMON STOCK WARRANT AGREEMENT 

THIS 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 will be issued in connection with the issuance of the Other Securities but shall 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 will be issued
with the Other Securities and each Warrant Certificate will evidence [●] Warrants for each [$[●] principal amount] [[●] shares] of Other Securities issued.]  

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 such 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. 

  
 1 

 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.  

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., [City] 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., [City] 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. 

  
 2 

 (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, 

  
 3 

 (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 

  
 4 

 
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 

  
 5 

 
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., [City] 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. 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. 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.

CONCERNING THE WARRANT AGENT

appointment. The Warrant Agent shall have the powers and authority granted to and conferred upon it in the Warrant Certificates and hereby and such further powers and authority to act on behalf of the Company as the Company may hereafter grant to or

 6 

 5.2 Conditions Of Warrant Agent’s Obligations. The Warrant Agent accepts its obligations
herein set forth upon the terms and conditions hereof, including the following to all of which the Company agrees and to all of which the rights hereunder of the holders from time to time of the Warrant Certificates shall be subject: 

(a) Compensation And Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation to be agreed 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 of, or acquire any interest in,
Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted by applicable law, it or they may engage or be interested in any financial or other 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 this Warrant Agreement shall be deemed
to prevent the Warrant Agent from acting as trustee under any indenture to which the Company is a party. 
 (f) No Liability For Interest.
Unless otherwise agreed with the Company, the Warrant Agent shall have no liability for interest on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates. 

(g) No Liability For Invalidity. The Warrant Agent shall have no liability with respect to any invalidity of this Agreement or any of the
Warrant Certificates (except as to the Warrant Agent’s countersignature thereon). 
 (h) No Responsibility For Representations. The
Warrant Agent shall not be responsible for any of the recitals or representations herein or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon), all of which are made solely by the Company. 

(i) No Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as are herein and in the 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. 

(a) The Company agrees, for the benefit of the holders from time to time of the 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 

  
 7 

 
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 officer shall take charge or control of the Warrant Agent or of its property or affairs for the purpose of rehabilitation, conservation, winding up
or liquidation, a successor Warrant Agent, qualified as aforesaid, shall be appointed by the Company by an instrument in writing, filed with the successor Warrant Agent. Upon the appointment as aforesaid of a successor Warrant Agent and acceptance
by the successor Warrant Agent of such appointment, the Warrant Agent shall cease to be Warrant 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
of any of the parties hereto.
