Section 4. Dividends. 
 (a) Rate. Holders of Series A shall be entitled to receive, on each share of Series A, out of funds legally available for the payment of dividends under Delaware law, cumulative cash dividends at a
per annum rate of 12% on the Liquidation Preference. Such dividends shall begin to accrue and be cumulative from the Original Issue Date of such share, shall compound on each Dividend Payment Date (i.e., no dividends shall accrue on other
dividends unless and until the first Dividend Payment Date for such other dividends has passed without such other dividends having been paid on such date), and shall be payable in arrears (as provided in this Section 4(a)). Through
December 31, 2014, dividends shall be payable only when, as and if declared by the Board of Directors. Thereafter, the Board of Directors shall declare dividends, payable on each Dividend Payment Date, subject only to the legal availability of
funds for declaration and payment thereof. If any such Dividend Payment Date would otherwise occur on a day that is not a Business Day, such Dividend Payment Date shall instead be (and any dividend payable on Series A on such Dividend Payment Date
shall instead be payable on) the immediately succeeding Business Day with the same force and effect as if made on such Dividend Payment Date. The amount of dividends payable on the Series A shall be computed on the basis of a 360-day year consisting
of twelve 30-day months, and with respect to any date of determination that is not a Dividend Payment Date, actual days elapsed over a 30-day month. 
 Dividends that are payable on Series A on any Dividend Payment Date shall be payable to holders of record of Series A as they appear on the stock register of the Corporation on the applicable record date,
which shall be the 15th calendar day before such Dividend Payment Date (as originally scheduled) or such other record date fixed by the Board of Directors that is not more than 60 nor less than 10 days prior to such Dividend Payment Date (each, a
“Dividend Record Date”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day. 

  
 4 

 Each dividend period (a “Dividend Period”) shall commence on the calendar
day immediately following a Dividend Payment Date (other than the initial Dividend Period with respect to any share of Series A, which shall commence on and include the Original Issue Date of such share) and shall end on and include the next
Dividend Payment Date. Dividends payable in respect of a Dividend Period shall be payable in arrears on the Dividend Payment Date ending such Dividend Period. 
 (b) Priority of Dividends. When dividends are not paid (or declared and a sum sufficient for payment thereof set aside for the benefit of the holders thereof on the applicable Dividend Record Date)
on any Dividend Payment Date in full upon the Series A, all dividends declared on the Series A and payable on such Dividend Payment Date shall be declared pro rata so that the respective amounts of such dividends declared shall bear the same
ratio to each other as all accrued and unpaid dividends per share on the Series A (including, if applicable as provided in Section 4(a) above, dividends on such amount) bear to each other. 

Section 5. Liquidation Rights. 
 (a) Voluntary or Involuntary Liquidation. In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, holders of Series A shall
be entitled to receive for each share of Series A, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to stockholders of the Corporation, and after satisfaction of all liabilities and
obligations to creditors of the Corporation, before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other Junior Stock, payment in full in an amount equal to the Liquidation Preference of
such share. 
 (b) Partial Payment. If in any distribution described in Section 5(a) above, the assets of the
Corporation or proceeds thereof are not sufficient to pay the Liquidation Preferences in full to all holders of Series A as to such distribution, the amounts paid to the holders of Series A shall be paid pro rata in accordance with the
respective aggregate Liquidation Preferences of the holders of Series A. 
 (c) Residual Distributions. If the Liquidation
Preference has been paid in full to all holders of Series A, the holders of other stock of the Corporation shall be entitled to receive all remaining assets of the Corporation (or proceeds thereof) according to their respective rights and
preferences. 
 (d) Merger, Consolidation and Sale of Assets Not Liquidation. For purposes of this Section 5, the
merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Series A receive cash, securities or other property for their shares, or the sale, lease or exchange
(for cash, securities or other property) of all or substantially all of the assets of the Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation, but shall be governed by Section 7. 

  
 5 

 Section 6. Redemption. 

(a) Mandatory Redemption. On March 21, 2018, the Corporation shall redeem, in whole, the shares of Series A at the time
outstanding, upon notice given as provided in Section 6(c) below, at a redemption price per share equal to 100% of the Liquidation Preference of such share as of the redemption date. The redemption price for any shares of Series A shall be
payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent. 
 (b) Optional Redemption. From and after one year from the Original Issue Date until March 21, 2018, the Corporation, at its option, may redeem, in whole at any time or in part from time to
time, the shares of Series A at the time outstanding, upon notice given as provided in Section 6(c) below, at a redemption price per share equal to 110% of the Liquidation Preference of such share as of the redemption date, provided that
the minimum number of shares of Series A redeemable at any time is the lesser of (i) 500 shares of Series A and (ii) the number of shares of Series A outstanding. The redemption price for any shares of Series A shall be payable on the
redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent. 
 (c) Notice of Redemption. Notice of every redemption of shares of Series A shall be given to the holders of record of the shares to be redeemed at their respective last addresses appearing on the
books of the Corporation. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this Subsection shall be conclusively presumed to have been duly given, whether or not
the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Series A designated for redemption shall not affect the validity of the proceedings for
the redemption of any other shares of Series A. Each notice of redemption given to a holder shall state: (1) the redemption date; (2) the number of shares of Series A to be redeemed and, if less than all the shares held by such holder are
to be redeemed, the number of such shares to be redeemed from such holder; (3) the redemption price; and (4) the place or places where certificates for such shares are to be surrendered for payment of the redemption price. 

(d) Partial Redemption. In case of any redemption of part of the shares of Series A at the time outstanding, the shares to be
redeemed shall be selected pro rata among holders of the Series A. If fewer than all the shares represented by any certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without charge to the holder
thereof. 
 (e) Effectiveness of Redemption. If notice of redemption has been duly given and if on or before the
redemption date specified in the notice all funds necessary for the redemption have been deposited by the Corporation, in trust for the pro rata benefit of the holders of the shares called for redemption, with a bank or trust company doing
business in the Borough of Manhattan, The City of New York, and having a capital and surplus of at least $500 million and selected by the Board of Directors, so as to be and continue to be available solely therefor, then, notwithstanding that any
certificate for any share so called for redemption has not been surrendered for cancellation, on and after the redemption date dividends shall cease to accrue on 

  
 6 

 
all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date
cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption from such bank or trust company, without interest. Any funds unclaimed at the end of three years from the redemption date shall, to
the extent permitted by law, be released to the Corporation, after which time the holders of the shares so called for redemption shall look only to the Corporation for payment of the redemption price of such shares. 

Section 7. Offer to Purchase Upon a Change of Control. 

(a) In connection with the occurrence of a Change of Control, the Corporation shall make an offer to purchase all of the shares of
Series A outstanding (a “Change of Control Offer”) on the terms set forth in this Section 7. The Change of Control Offer shall be made in compliance with all applicable laws, including, without limitation (if applicable),
Regulation 14E and 14D under the Exchange Act and the rules thereunder and all other applicable Federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this
Section 7, the Corporation shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 7 by virtue thereof.

consummation, or anticipated consummation, of a Change of Control, the Corporation shall commence the Change of Control Offer by mailing to each holder of shares of Series A a notice, which shall govern the terms of the Change of Control Offer, and

Series A tendered will be accepted for payment subject to the consummation of the Change of Control;

 (iii) that any shares of Series A
not tendered for payment pursuant to the Change of Control Offer shall continue to accrue dividends and be redeemable in accordance with the terms hereof; 
 (iv) that, unless the Corporation defaults in the payment of the Change of Control Price, all shares of Series A accepted for payment pursuant to the Change of Control Offer shall cease to accrue
dividends on the Change of Control Payment Date;

Series A, the number of shares of Series A such holder delivered for purchase, and a statement that such holder is withdrawing its election to have such shares of Series A purchased;

unpurchased shares of Series A represented by any certificate surrendered; 
 (viii) the instructions that holders must
follow in order to tender their shares of Series A; and

available therefore and otherwise lawful, accept for payment the shares of Series A tendered and not withdrawn pursuant to the Change of Control Offer. The Corporation shall promptly mail to each holder of shares of Series A so accepted payment (or
pay in person any holder presenting itself at the Corporation) in an amount equal to the purchase price for such shares, and the unpurchased shares of Series A surrendered, if any. 

(d) The Corporation shall make a public announcement of the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Payment Date.

 3. Exercise of Warrant; Term.

York City time, on the date that is ninety (90) months after the Issue Date (the “Expiration Time”), by (A) the surrender of this Warrant and Notice of Exercise annexed hereto, duly completed and executed on behalf of the
Warrantholder, at the principal executive office of the Corporation located at 210 Park Avenue, Suite 2750, Oklahoma City, OK 73102 (or such other office or agency of the Corporation in the United States as it may designate by notice in writing to
the Warrantholder at the address of the Warrantholder appearing on the books of the 

  
 3 

 
Corporation), and (B) payment of the Exercise Price for the Shares thereby purchased at the election of the Warrantholder by (i) tendering in cash, by certified or cashier’s check
payable to the order of the Corporation, or by wire transfer of immediately available funds to an account designated by the Corporation, (ii) electing a cashless exercise pursuant to Section 3(b), or (iii) offsetting the Exercise
Price against the Warrantholder’s Series A Liquidation Preference as set forth in Section 3(c). 
 (b) If, as of the
day immediately preceding the time a Notice of Exercise is delivered to the Corporation, the Market Price of one Share is greater than the Exercise Price, in lieu of exercising this Warrant for cash, the Warrantholder may elect to receive Shares
equal to the value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant and Notice of Exercise (which shall include notice of such election) in which event the Corporation shall issue to the
Warrantholder a number of Shares computed using the following formula: 
  

					
		 	X = Y (A-B)	  	
		 	            A	  	
			
		 	Where:	  	
		 	   X = the number of Shares to be issued to the Warrantholder

		 	   Y = the number of Shares purchasable under the Warrant or, if only a portion of the Warrant
is being
   exercised, the portion of the Warrant being exercised

		 	   A = the Market Price of one Share set forth above

		 	   B = the Exercise Price

 (c) In lieu of exercising this Warrant for cash, the Warrantholder may elect to pay the aggregate
Exercise Price payable for the Shares being purchased by delivering to the Corporation for cancellation such number of shares of Series A held by the Warrantholder having an aggregate Liquidation Preference equal to such aggregate Exercise Price as
of the date of such payment. 
 (d) If the Warrantholder does not exercise this Warrant in its entirety, the Warrantholder will
be entitled to receive from the Corporation within a reasonable time, and in any event not exceeding five business days, a new warrant in substantially identical form for the purchase of that number of Shares equal to the difference between the
number of Shares subject to this Warrant and the number of Shares as to which this Warrant is so exercised. Notwithstanding anything in this Warrant to the contrary, the Warrantholder hereby acknowledges and agrees that its exercise of this Warrant
for Shares is subject to the condition that the Warrantholder will have first received any applicable Regulatory Approvals. 

4. Forced Exercise. 
 (a) After the Effective Date, if the Conditions to Forced Exercise have been satisfied, the Corporation may force exercise of this Warrant by the Warrantholder, in whole or in part, as set forth in this
Section 4, by delivering to the Warrantholder a notice thereof in the form annexed hereto (“Forced Exercise Notice”), duly completed and executed on behalf of the Corporation. The aggregate number of Shares to be exercised with
respect to all warrants issued pursuant to 

  
 4 

 
the Purchase Agreement and the 2010 Purchase Agreement, including this Warrant (the “Forced Shares”), shall not be less than 750,000 or greater than 50% of the trading volume of
the Common Stock during the twenty (20) trading days preceding the date of the Forced Exercise Notice. Within forty (40) business days after receipt of the Forced Exercise Notice, the Warrantholder shall deliver to the Corporation a Notice
of Exercise as set forth in Section 3(a) for the Forced Shares applicable to this Warrant. If at any time prior to the delivery of the Notice of Exercise by the Warantholder, the Conditions to Forced Exercise cease to be met, the Forced
Exercise Notice shall be deemed to have been revoked. 
 (b) In no event shall the Warrantholder be forced to exercise in excess
of 50% of all Shares issuable hereunder nor shall the Corporation be permitted to deliver more than one Forced Exercise Notice in any three (3) month period. If the Corporation forces an exercise pursuant to this Section 4, it must then
simultaneously take the same action in the same proportion with respect to any other warrants issued pursuant to the Purchase Agreement. 
 (c) For purposes of this Section 4: 
 “Conditions to Forced
Exercise” means that each of the following conditions have been met: (i) the Weighted Average Price of the Common Stock exceeds 300% of the Exercise Price (subject to appropriate adjustments for stock splits, stock dividends, stock
combinations and other similar transactions after the Issue Date) for the thirty (30) consecutive trading days immediately preceding the date of delivery of the Forced Exercise Notice; (ii) a registration statement is effective and
available for the resale of all remaining Common Stock issuable upon exercise of the Warrants; (iii) the Common Stock is designated for quotation on the NASDAQ Global Market or another U.S. national securities exchange and must not have been
suspended from trading on such market nor shall delisting or suspension by such market been threatened or pending either (A) in writing by such market, or (B) by falling below the minimum listing maintenance requirements of such market;
and (iv) the Corporation otherwise must be in material compliance with and must not have breached in any material respect any provision, covenant, representation or warranty of any Transaction Document that remains uncured. 

“Weighted Average Price” means, with respect to the Common Stock as of any date, the dollar volume-weighted average
price for such security on the NASDAQ Global Market or, if the Common Stock is no longer traded on the NASDAQ Global Market, the principal U.S. national securities exchange on which the Common Stock is then traded, during the period beginning at
9:30:01 a.m., New York Time (or such other time as the NASDAQ Global Market or such exchange publicly announces is the official open of trading), and ending at 4:00:00 p.m., New York Time (or such other time as the NASDAQ Global Market or such
exchange publicly announces is the official close of trading) as reported by Bloomberg through its “Volume at Price” functions. 
 5. Issuance of Shares; Authorization; Listing. Subject to compliance with the transfer restrictions applicable to this Warrant and the Shares pursuant to the provisions hereof and the Purchase
Agreement, certificates for Shares issued upon exercise of this Warrant shall be issued in such name or names as the Warrantholder may designate and shall be delivered to such named Person or Persons within a reasonable time, not to exceed three
business days after the date on which this Warrant has been duly exercised and the Exercise Price for the Shares thereby 

  
 5 

 
purchased has been duly delivered, in accordance with the terms of this Warrant. The Corporation hereby represents and warrants that any Shares issued upon the exercise of this Warrant in
accordance with the provisions of Section 3 will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges (other than liens or charges created by the Warrantholder, except as otherwise
provided herein, income and franchise taxes incurred in connection with the exercise of the Warrant or taxes in respect of any transfer occurring contemporaneously therewith). The Shares so issued shall be deemed to have been issued to the
Warrantholder as of the close of business on the date on which this Warrant and payment of the Exercise Price are delivered to the Corporation in accordance with the terms of this Warrant, notwithstanding that the stock transfer books of the
Corporation may then be closed or certificates representing such Shares may not be actually delivered on such date. The Corporation shall at all times reserve and keep available, out of its authorized but unissued Common Stock, solely for the
purpose of providing for the exercise of this Warrant, the aggregate number of shares of Common Stock issuable upon exercise of this Warrant. The Corporation shall (A) procure, at its sole expense, the listing of the Shares issuable upon
exercise of this Warrant, subject to issuance or notice of issuance, on all principal stock exchanges on which the Common Stock is then listed or traded and (B) maintain such listings of such Shares at all times after issuance. The Corporation
shall use reasonable best efforts to ensure that the Shares may be issued without violation of any applicable law or regulation or of any requirement of any securities exchange on which the Shares are listed or traded. The Corporation and the
Warrantholder shall reasonably cooperate to take such other actions as are necessary to obtain (i) any Regulatory Approvals applicable to Warrantholder’s exercise of its rights hereunder, including with respect to the issuance of the
Shares and (ii) any regulatory approvals applicable to the Corporation as a result of the issuance of the Shares. 
 6.
No Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall be issued upon any exercise of this Warrant. In lieu of any fractional Share to which the Warrantholder would otherwise be entitled, the
Warrantholder shall be entitled to receive a cash payment equal to the Market Price of the Common Stock on the last trading day preceding the date of exercise less the Exercise Price for such fractional share; provided, however, that the
Corporation may, at its option, round up to the nearest whole share of Common Stock in lieu of any cash payment. 
 7. No
Rights as Stockholders; Transfer Books. This Warrant does not entitle the Warrantholder to any voting rights or other rights as a stockholder of the Corporation prior to the date of exercise hereof. The Corporation shall at no time close its
transfer books against transfer of this Warrant in any manner which interferes with the timely exercise of this Warrant. 
 8.
Charges, Taxes and Expenses. Issuance of certificates for Shares to the Warrantholder upon the exercise of this Warrant shall be made without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of
the issuance of such certificates, all of which taxes and expenses shall be paid by the Corporation. 

  
 6 

 9. Transfer/Assignment. 

(a) Subject to compliance with clauses (b) and (c) of this Section 9, this Warrant and all rights hereunder are
transferable, in whole or in part, upon the books of the Corporation by the registered holder hereof in person or by duly authorized attorney, and a new warrant shall be made and delivered by the Corporation, of the same tenor and date as this
Warrant but registered in the name of one or more transferees, upon surrender of this Warrant, duly endorsed, to the office or agency of the Corporation described in Section 3. All expenses (other than stock transfer taxes) and other charges
payable in connection with the preparation, execution and delivery of the new warrants pursuant to this Section 9 shall be paid by the Corporation. 
 (b) Notwithstanding the foregoing, this Warrant and any rights hereunder, and any Shares issued upon exercise of this Warrant, shall be subject to the applicable restrictions as set forth in
Section 4.3 of the Purchase Agreement. 
 (c) If and for so long as required by the Purchase Agreement, this Warrant
Certificate shall contain a legend as set forth in Section 4.4 of the Purchase Agreement. 
 10. Exchange and Registry
of Warrant. This Warrant is exchangeable, upon the surrender hereof by the Warrantholder to the Corporation, for a new warrant or warrants of like tenor and representing the right to purchase the same aggregate number of Shares. The Corporation
shall maintain a registry showing the name and address of the Warrantholder as the registered holder of this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance with its terms, at the office of the Corporation, and the
Corporation shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry. 
 11.
Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Corporation of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or
destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Corporation, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Corporation shall make and deliver, in lieu of such
lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same aggregate number of Shares as provided for in such lost, stolen, destroyed or mutilated Warrant. 

12. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right
required or granted herein shall not be a business day, then such action may be taken or such right may be exercised on the next succeeding day that is a business day. 
 13. Rule 144 Information. The Corporation shall use its reasonable best efforts to timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange
Act and the rules and regulations promulgated by the SEC thereunder (or, if the Corporation is not required to file such reports, it shall, upon the request of any Warrantholder, make publicly available such information as necessary to permit sales
pursuant to Rule 144 or Regulation S under the Securities Act), and it shall use reasonable best efforts to take such further action as any Warrantholder may reasonably request, in each case to the extent required from time to time to enable such
holder to, if permitted by the terms of this Warrant and the Purchase Agreement, sell this Warrant without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144 or Regulation S under the
Securities Act, 

  
 7 

 
as such rules may be amended from time to time, or (B) any successor rule or regulation hereafter adopted by the SEC. Upon the written request of any Warrantholder, the Corporation will
deliver to such Warrantholder a written statement that it has complied with such requirements. 
 14. Adjustments and Other
Rights. The Exercise Price and the number of Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows: 
 (a) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Corporation shall (i) declare and pay a dividend or make a distribution on its Common Stock in shares of Common Stock,
(ii) subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Shares issuable upon
exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder after such date shall be
entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this Warrant after such date had this Warrant been exercised immediately
prior to such date. In such event, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted to the number obtained by
dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the
dividend, distribution, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of Shares issuable upon exercise of the Warrant determined pursuant to the immediately preceding sentence. 

(b) Reorganization, Consolidation, Merger and Other Changes. In case of any capital reorganization or change in the Common Stock of
the Corporation (other than as a result of a subdivision, combination, or stock dividend provided for in Section 14(a) above), or consolidation or merger of the Corporation with or into another entity, or the sale of all or substantially all of
its assets to another entity shall be effected in such a way that holders of the Corporation’s Common Stock shall be entitled to receive stock, securities or assets with respect to or in exchange for such Common Stock, then, as a condition of
such reorganization, change, consolidation, merger or sale, lawful provision shall be made, and duly executed documents evidencing the same from the Corporation or its successor shall be delivered to the Warrantholder, so that the Warrantholder
shall have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and other securities and property receivable in
connection with such reclassification, reorganization, change, consolidation, merger or sale by a holder of the same number of shares of Common Stock as were purchasable by the Warrantholder immediately prior to such reclassification,
reorganization, change, consolidation, merger or sale. In any such case appropriate provisions shall be made with respect to the rights and interest of the Warrantholder so that the provisions hereof shall thereafter be applicable with respect to
any shares of stock or other securities and property deliverable upon exercise hereof, and appropriate adjustments shall be made to the purchase price per share payable hereunder, provided the aggregate purchase price shall remain the same.

  
 8 

 (c) Whenever the Exercise Price or the number of Shares into which this Warrant is
exercisable shall be adjusted as provided in this Section 14, the Corporation shall forthwith file at the principal office of the Corporation a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price
that shall be in effect and the number of Shares into which this Warrant shall be exercisable after such adjustment, and the Corporation shall also cause a copy of such statement to be sent to each Warrantholder at the address appearing in the
Corporation’s records. 
 15. Governing Law. This Warrant will be governed by and construed in accordance with
the laws of the State of New York applicable to contracts made and to be performed entirely within such State. Each of the parties hereto agrees (a) to submit to the non-exclusive personal jurisdiction of the State or Federal courts in the
Borough of Manhattan, The City of New York, (b) that non-exclusive jurisdiction and venue shall lie in the State or Federal courts in the State of New York, and (c) that notice may be served upon such party at the address and in the manner
set forth for such party in Section 3 hereof. To the extent permitted by applicable law, each of the parties hereto hereby unconditionally waives trial by jury in any legal action or proceeding relating to the Transaction Documents or the
transactions contemplated hereby or thereby.  
 16. Binding Effect. This Warrant shall be binding upon any
successors or assigns of the Corporation. 
 17. Amendments. This Warrant may be amended and the observance of any term
of this Warrant may be waived only with the written consent of the Corporation and the Warrantholder. 
 18. Notices. Any
notice, request, instruction or other document to be given hereunder by any party to the other will be in writing and will be deemed to have been duly given (a) on the date of delivery if delivered personally, or by facsimile, upon confirmation
of receipt, or (b) on the second business day following the date of dispatch if delivered by a recognized next day courier service. All notices hereunder shall be delivered as set forth below, or pursuant to such other instructions as may be
