 (iv) Each Warrant issued prior to the Separation Date will bear the Unit
Legend which may be contained on the face of the Unit. 
 (c) (i) If the Company determines (upon the advice of counsel and such
other certifications and evidence as the Company may reasonably require) that a Warrant is eligible for resale pursuant to Rule 144 under the Securities Act (or a successor provision) without the need to satisfy current information or other
requirements therein and that the Restricted Legend is no longer necessary or appropriate in order to ensure that subsequent transfers of the Warrant (or a beneficial interest therein) are effected in compliance with the Securities Act, or

 (ii) after a Warrant is sold pursuant to an effective registration statement under the Securities Act,

 the Company may instruct the Warrant Agent in writing to cancel the Warrant and issue to the Holder thereof (or to its transferee) a new
Warrant of like tenor, registered in the name of the Holder thereof (or its transferee), that does not bear the Restricted Legend, and the Warrant Agent will comply with such instruction. 

(d) By its acceptance of any Warrant bearing the Restricted Legend (or any beneficial interest in such a Warrant), each Holder thereof

 Section 3.03 . Warrant Registrar And Countersignature Agent. The Company may
appoint one or more Registrars, and the Warrant Agent may appoint a Countersignature Agent, in which case each reference in this Agreement to the Warrant Agent in respect of the obligations of the Warrant Agent to be performed by that Agent will be
deemed to be references to the Agent. The Company may act as Registrar. In each case the Company and the Warrant Agent will enter into an appropriate agreement with the Agent implementing the provisions of this Agreement relating to the obligations
of the Warrant Agent to be performed by the Agent and the related rights. The Company initially appoints the Warrant Agent as Registrar. 
 Section 3.04 . Replacement Warrants. If a mutilated Warrant is surrendered to the Warrant Agent or if a Holder claims that its Warrant has been lost, destroyed or wrongfully taken, the
Company will issue and the Warrant Agent will countersign a replacement Warrant. Every replacement Warrant is an additional obligation of the Company and entitled to the benefits of this Agreement. If required by the Warrant Agent or the Company, an
indemnity must be furnished by the Holder that is sufficient in the judgment of (i) the Warrant Agent to protect the Warrant Agent and (ii) the Company to protect the Company and the Warrant Agent from any loss they may suffer if a Warrant
is replaced. The Company may charge the Holder for the expenses of the Company and the Warrant Agent in replacing a Warrant. 

Section 3.05 . Outstanding Warrants. (a) Warrants outstanding at any time are all Warrants that have been countersigned by
the Warrant Agent except for 
 (i) Warrants cancelled by the Warrant Agent or delivered to it for cancellation;

 (ii) Warrants exercised by the Holder thereof; and 

(iii) any Warrant which has been replaced pursuant to Section 3.04 unless and until the Warrant Agent and the
Company receive proof satisfactory to them that the replaced Warrant is held by a bona fide purchaser, in which case the replacement Warrant issued pursuant to Section 3.04 shall be automatically cancelled. 

(b) A Warrant does not cease to be outstanding because the Company or one of its Affiliates holds the Warrant, provided that in
determining whether the Holders of the requisite principal amount of the outstanding Warrants have given or taken any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, Warrants owned by the Company or any
Affiliate of the Company will be disregarded and deemed not to be outstanding (it being understood that in determining whether the Warrant Agent is protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver
or other action, only Warrants which the Warrant Agent knows to be so owned will be so disregarded). Warrants so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Warrant
Agent the pledgee’s right so to act with respect to such Warrants and that the pledgee is not the Company or any Affiliate of the Company.

 Section 3.06 . Temporary Warrants. Until definitive Warrants are ready for
delivery, the Company may prepare and the Warrant Agent will countersign temporary Warrants. Temporary Warrants will be substantially in the form of definitive Warrants but may have insertions, substitutions, omissions and other variations
determined to be appropriate by the Officer executing the temporary Warrants, as evidenced by the execution of the temporary Warrants. If temporary Warrants are issued, the Company will cause definitive Warrants to be prepared without unreasonable
delay. After the preparation of definitive Warrants, the temporary Warrants will be exchangeable for definitive Warrants upon surrender of the temporary Warrants without charge to the Holder. Upon surrender for cancellation of any temporary
Warrants, the Company will execute and the Warrant Agent will countersign and deliver in exchange therefor a like amount of definitive Warrants. Until so exchanged, the temporary Warrants will be entitled to the same benefits under this Agreement as
definitive Warrants. 
 Section 3.07 . Cancellation. The Company at any time may deliver to the Warrant Agent for
cancellation any Warrants previously countersigned and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Warrant Agent for cancellation any Warrants previously countersigned hereunder which the
Company has not issued and sold. Any Registrar will forward to the Warrant Agent any Warrants surrendered to it for transfer, exchange or exercise. The Warrant Agent will cancel all Warrants surrendered for transfer, exchange, exercise or
cancellation and dispose of them in accordance with its normal procedures. Certification of the cancellation of all cancelled Warrants shall be delivered to the Company upon written request. The Company may not issue new Warrants to replace Warrants
that have been exercised or delivered to the Warrant Agent for cancellation. 
 Section 3.08 . CUSIP Numbers. The
Company in issuing the Warrants may use “CUSIP” numbers, and the Warrant Agent will use CUSIP numbers in notices as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either
as printed on the Warrants or as contained in any notice to any Holder. The Company will promptly notify the Warrant Agent in writing of any change in the CUSIP numbers. 
 Section 3.09 . Registration, Transfer And Exchange. (a) The Warrants will be issued in registered form only, and the Company shall cause the Warrant Agent to maintain a register (the
“Register”) of the Warrants, for registering the record ownership of the Warrants by the Holders and transfers and exchanges of the Warrants. 
 (b) (i) Each Global Warrant will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend. 

(ii) Each Global Warrant will be delivered to the Warrant Agent as custodian for the Depositary. Transfers of a Global
Warrant (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except (1) as set forth in Section 3.09(b)(iv) and
(2) transfers of portions thereof in the form of Certificated Warrants may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to the Warrant Agent by or on behalf of the Depositary in
accordance with customary procedures of the Depositary and in compliance with this Section and Section 3.10.

Table of Contents



 (iii) Agent Members will have no rights under this Agreement with respect to
any Global Warrant held on their behalf by the Depositary, and the Depositary may be treated by the Company, the Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner and Holder of such Global Warrant for all purposes
whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Warrant through an Agent Member) to
take any action which a Holder is entitled to take under the Warrant or the Warrants, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a
holder of any security. 
 (iv) If (1) the Depositary (a) notifies the Company that it is unwilling or
unable to continue as Depositary for a Global Warrant or (y) has ceased to be a clearing agency registered under the Exchange Act, and in each case a successor depositary is not appointed by the Company within 90 days of the notice; or
(2) the Company, at its option, notifies the Warrant Agent in writing that it elects to cause the issuance of Certificated Warrants, the Warrant Agent will promptly exchange each beneficial interest in the Global Warrant for one or more
Certificated Warrants in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Warrant Agent by the Depositary, and thereupon the Global Warrant will
be deemed canceled. If such Global Warrant does not bear the Restricted Legend, then the Certificated Warrants issued in exchange therefor will not bear the Restricted Legend. Except as otherwise provided in Section 3.01(c)(i) and (ii), if such
Global Warrant bears the Restricted Legend, then the Certificated Warrants issued in exchange therefor will bear the Restricted Legend. 
 (c) Each Certificated Warrant will be registered in the name of the holder thereof or its nominee. 
 (d) Prior to the Separation Date, when a Note issued under the Indenture is transferred, the Warrant associated with such Note shall be automatically transferred to the same party and during such period
each time a notation of a transfer of a Note is made on the register for the Notes maintained under the Indenture, a corresponding notation shall be made in the Register. On and after the Separation Date, a Holder may transfer a Warrant (or a
beneficial interest therein) to another Person or exchange a Warrant (or a beneficial interest therein) for another Warrant by presenting to the Warrant Agent a written request therefor stating the name of the proposed transferee or requesting such
an exchange, accompanied by any certification, opinion or other document required by this Agreement. The Warrant Agent will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the Register
maintained by the Warrant Agent for the purpose; provided that no transfer or exchange will be effective until it is registered in the Register. Prior to the registration of any transfer, the Company, the Warrant Agent and their agents will
treat the Person in whose name the Warrant is registered as the owner and Holder thereof for all purposes, and will not be affected by notice to the contrary.

 Neither the Company nor any agent of the Company shall have any responsibility or liability
for any aspect of the records on account of beneficial ownership interests of a Global Warrant, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

From time to time the Company will execute and the Warrant Agent will countersign additional Warrants as necessary in order to permit the
registration of a transfer or exchange in accordance with this Section. All Warrants issued upon transfer or exchange shall be the duly authorized, executed and delivered Warrants of the Company entitled to the benefits of this Agreement.

 No service charge will be imposed in connection with any transfer or exchange of any Warrant, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange pursuant to Section 3.09(b)(iv)).

 (e) (i) Global Warrant to Global Warrant. Subject to compliance with Section 3.10(b), if a beneficial interest in
a Global Warrant is transferred or exchanged for a beneficial interest in another Global Warrant, the Warrant Agent will (x) record a decrease in the amount of the Global Warrant being transferred or exchanged equal to the amount of such
transfer or exchange and (y) record a like increase in the amount of such other Global Warrant. Any beneficial interest in one Global Warrant that is transferred to a Person who takes delivery in the form of an interest in another Global
Warrant, or exchanged for an interest in another Global Warrant, will, upon transfer or exchange, cease to be an interest in such Global Warrant and become an interest in the other Global Warrant and, accordingly, will thereafter be subject to all
transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Warrant for as long as it remains such an interest. 

(ii) Global Warrant to Certificated Warrant. Subject to compliance with Section 3.10(b), if a beneficial
interest in a Global Warrant is transferred or exchanged for a Certificated Warrant, the Warrant Agent will (x) record a decrease in the principal amount of such Global Warrant equal to the principal amount of such transfer or exchange and
(y) deliver a new Certificated Warrants to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as applicable. 

(iii) Certificated Warrant to Global Warrant. Subject to compliance with Section 3.10(b), if a Certificated
Warrant is transferred or exchanged for a beneficial interest in a Global Warrant, the Warrant Agent will (x) cancel such Certificated Warrant, (y) record an increase in such Global Warrant equal to the number of Warrants being transferred
or exchanged and (z) in the event that such transfer or exchange involves less than the entire amount of the canceled Certificated Warrant, deliver to the Holder thereof one or more new Certificated Warrants having an aggregate number of
Warrants equal to the untransferred or unexchanged portion of the canceled Certificated Warrant, registered in the name of the Holder thereof.

 (iv) Certificated Warrant to Certificated Warrant. Subject to
compliance with Section 3.10(b), if a Certificated Warrant is transferred or exchanged for another Certificated Warrant, the Warrant Agent will (x) cancel the Certificated Warrant being transferred or exchanged, (y) deliver one or
more new Certificated Warrants having an aggregate principal amount equal to the amount of Warrants being transferred or exchanged to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Warrant (in the case of an
exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire amount of the canceled Certificated Warrant, deliver to the Holder thereof one or more

 ARTICLE 4 
 SEPARATION OF WARRANTS; TERMS OF WARRANTS; EXERCISE OF WARRANTS

 Section 4.01 . Separation Of Warrants; Terms Of Warrants; Exercise Of Warrants. (a) The Notes and Warrants
will not be separately transferable until the Separation Date. The Company shall provide written notice to the Warrant Agent upon the occurrence of the Separation Date. The Warrant Agent shall not be deemed to have any knowledge of the occurrence of
such Separation Date until it receives such notice from the Company. On the Separation Date, the Unit Legend shall be deemed removed from the Warrant, or face of Unit, and, whether or not such Unit Legend is actually removed, each Warrant shall be
deemed automatically separated from the associated Note and may be transferred separately from such Note. Each Warrant not exercised prior to 5:00 p.m., New York City time, on November 15, 2021 (the “Expiration Date”) shall
become void and all rights thereunder and all rights in respect thereof under this agreement shall cease as of such time. 
 (b)
Subject to the terms of this Agreement, the Warrants shall be exercisable, at the election of the Holders thereof, either in full or from time to time in part during the period commencing at the opening of business on the Separation Date and until
5:00 p.m., New York City time, on the Expiration Date, and shall entitle any Holder thereof to receive from the Company the number of fully paid and nonassessable Warrant Shares which the Holder may at the time be entitled to receive on exercise of
such Warrants and payment of the exercise price set forth in the form of Warrant attached as Exhibit A hereto (as adjusted from time to time hereunder, the “Exercise Price”) in cash, by wire transfer or by certified or official
check payable to the order of the Company, in each case, equal to the Exercise Price then in effect for such Warrant Shares; provided that Holders shall be able to exercise their Warrants only if the exercise of such Warrants is exempt from,
or in compliance with, the registration requirements of the Securities Act and such securities are qualified for sale or exempt from qualification under the applicable securities laws of the states in which the various holders of the Warrants or
other persons to whom it is proposed that the Warrant Shares be issued on exercise of the Warrants reside. No adjustments as to dividends will be made upon exercise of the Warrants. 

(c) Notwithstanding anything herein to the contrary, (but in all other respects in accordance with the exercise procedure set forth
herein), a Holder may elect to convert Warrants into shares of Common Stock, in which event the Company will issue to the Holder the number of shares of Common Stock equal to the result obtained by (i) subtracting B from A, (ii) dividing
the result by A, and (iii) multiplying the quotient by C as set forth in the following equation: 
  
 



 
 where: 
 X = the number of shares of Common Stock issuable upon exercise pursuant to this paragraph (c).

Table of Contents




			
	 A =
	  	the Daily Price on the day immediately preceding the date on which the Holder delivers written notice to the Company pursuant to paragraph (d).
		
	 B =
	  	the Exercise Price.
		
	 C =
	  	the number of shares of Common Stock as to which the Warrants are then being exercised (prior to payment of the Exercise Price).

 If the foregoing calculation results in a negative number, then no shares of Common Stock shall be issued
upon exercise pursuant to this paragraph. 
 (d) In order to exercise all or any of the Warrants, the Holder thereof must
deliver to the Warrant Agent at its Corporate Trust Office (i) such Warrants, (ii) the form of election to purchase on the reverse thereof duly filled in and signed, which signature shall be medallion guaranteed by an institution which is
a member of a Securities Transfer Association recognized signature guarantee program, and (iii) payment to the Warrant Agent for the account of the Company of the then-current Exercise Price (in the manner set forth in paragraphs (b) or
(c) above) for the number of Warrant Shares in respect of which the Warrants are being exercised. 
 (e) Upon compliance
with the provisions set forth above, the Warrant Agent shall deliver such information and payment amount, if any, to the Company for verification and shall request in writing from the Company and the Company shall upon such verification deliver or
cause to be delivered with all reasonable dispatch, to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate or certificates for the number of whole Warrant Shares issuable upon the exercise of
such Warrants or other securities or property to which such Holder is entitled, together with cash in lieu of fractional shares as provided in Section 6.02 hereof. Such certificate or certificates or other securities or property shall be deemed
to have been issued, and any person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares or other securities or property, as of the date of the surrender of such Warrants and payment of the
Exercise Price, notwithstanding that the stock transfer books of the Company shall then be closed or the certificates or other securities or property have not been delivered. 
 (f) If less than all the Warrants represented by a Warrant certificate are exercised, such Warrant certificate shall be surrendered and a new Warrant certificate of the same tenor and for the number of
Warrants which were not exercised shall be executed by the Company and delivered to the Warrant Agent and the Warrant Agent shall countersign the new Warrant certificate, registered in such name or names as may be directed in writing by the Holder,
and shall deliver the new Warrant certificate to the Person or Persons entitled to receive the same. 
 (g) All Warrant
certificates surrendered upon exercise of Warrants shall be cancelled by the Warrant Agent. Such cancelled Warrant certificates shall then be cancelled and disposed of by the Warrant Agent in accordance with its standard procedures. The Warrant
Agent shall account promptly to the Company with respect to Warrants exercised and concurrently pay to the Company all monies received by the Warrant Agent for the purchase of the Warrant Shares through the exercise of such Warrants.

 (h) The Warrant Agent shall keep copies of this Agreement and any notices given or received
hereunder available for inspection by the Holders during normal business hours at its office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the Warrant Agent may request. 

(i) Certificates representing Warrant Shares shall bear a Restricted Legend (with all references to Warrants therein replaced by
references to Common Stock, and with such changes thereto as the Company may deem appropriate) if (i) the Warrants for which they were issued carried a Restricted Legend or (ii) the Warrant Shares are issued in a transaction exempt from
registration under the Securities Act (other than the exemption provided by Section 3(a)(9) of the Securities Act), in each case until and unless the circumstances set forth in Section 3.01(c) apply to such Shares, and any transfers
thereof shall comply with the Restricted Legend. 
 (j) Notwithstanding Sections 3.09(d) and 4.01(a), the Separation Date shall
in the case of any Global Warrant be subject to timing requirements imposed by the applicable rules and procedures of the Depositary in effecting a separation pursuant to clause (iv) of the definition of Separation Date. The Company shall use
commercially reasonable efforts to comply with the applicable rules and procedures of the Depositary in order to effect a separation of the Global Warrants and Global Notes on the Separation Date or as shortly thereafter as is practicable.

 ARTICLE 5 
 COVENANTS OF THE COMPANY 
 Section 5.01 . Maintenance Of Office Or Agency. The Company will maintain in the United States an office or agency where Warrants may be surrendered for registration of transfer or exchange
or for presentation for exercise. The Company hereby initially designates the Corporate Trust Office of the Warrant Agent as such office of the Company. The Company will give prompt written notice to the Warrant Agent of the location, and any change
in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Warrant Agent with the address thereof, such presentations, surrenders, notices and demands may be
made or served to the Warrant Agent. 
 The Company may also from time to time designate one or more other offices or agencies
where the Warrants may be surrendered or presented for any of such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Warrant Agent of any such designation or rescission and of any change
in the location of any such other office or agency.

documentary, stamp or similar issue or transfer taxes in respect of the issuance or delivery of Warrant Shares upon the exercise of Warrants; provided that the Company shall not be required to pay any tax or taxes which may be payable in
respect of any transfer involved in the issue of any Warrants or any Warrant Shares in a name other than that of the registered holder of a Warrant surrendered upon exercise (other than a transfer tax or other similar governmental charge payable
upon exchange pursuant to Section 3.09(b)(iv)), and the Company shall not be required to issue or deliver such Warrant unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax
or shall have established to the satisfaction of the Company that such tax has been paid.

Warrants or Warrant Shares remain outstanding and constitute “restricted securities” under Rule 144, the Company will make available upon request to any prospective purchaser of the Warrants or Warrant Shares or beneficial owner of
Warrants or Warrants Shares in connection with any sale thereof the information required by Rule 144A(d)(4) under the Securities Act.

 ARTICLE 6 
 ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES
ISSUABLE 
 Section 6.01 . Adjustment Of Exercise Price And Number Of Warrant Shares Issuable. The
Exercise Price and the number of Warrant Shares issuable upon the exercise of each Warrant are subject to adjustment from time to time upon the occurrence of the events enumerated in this Section 6.01. For purposes of this Section 6.01,
“Common Stock” means shares now or hereafter authorized of any class of common stock of the Company and any other stock of the Company, however designated, that has the right (subject to any prior rights of any class or series of
preferred stock) to participate in any distribution of the assets or earnings of the Company without limit as to per share amount. 
 In the event that, at any time as a result of the provisions of this Section, the Holders of the Warrants shall become entitled upon subsequent exercise to receive any shares of capital stock of the
Company other than Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall thereafter be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions
contained herein. 
 (a) Adjustment for Change in Capital Stock. 

If the Company (i) pays a dividend or makes a distribution on its Common Stock in shares of its Common Stock, (ii) subdivides
its outstanding shares of Common Stock into a greater number of shares, (iii) combines its outstanding shares of Common Stock into a smaller number of shares, (iv) makes a distribution on its Common Stock in shares of its capital stock
other than Common Stock or (v) issues by reclassification of its Common Stock any shares of its capital stock, then the Exercise Price in effect immediately prior to such action shall be proportionately adjusted so that the holder of any
Warrant thereafter exercised may receive the aggregate number and kind of shares of capital stock of the Company which he would have owned immediately following such action if such Warrant had been exercised immediately prior to such action.


  
 17 








Table of Contents



 The adjustment shall become effective immediately after the record date in the case of a
dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification. If, after an adjustment, a holder of a Warrant upon exercise of it may receive shares of two or more classes of capital
stock of the Company, the Company shall determine, in good faith, the allocation of the adjusted Exercise Price between the classes of capital stock. After such allocation, the exercise privilege and the Exercise Price of each class of capital stock
shall thereafter be subject to adjustment on terms comparable to those applicable to Common Stock in this Section 6.01. Such adjustment shall be made successively whenever any event listed above shall occur. 

(b) Adjustment for Rights Issue. 
 If the Company distributes any rights, options or warrants to all holders of its Common Stock entitling them for a period expiring within 45 days after the record date mentioned below to purchase shares
of Common Stock or securities convertible into, or exercisable or exchangeable for, Common Stock, at a price per share less than the Fair Value per share on that record date, the Exercise Price shall be adjusted in accordance with the formula:

  
 



 
 where: 
 E’ = the adjusted Exercise Price. 
 E = the then current
Exercise Price. 
 O = the number of shares of Common Stock outstanding on the record date. 

N = the number of additional shares of Common Stock issuable pursuant to such rights, options or warrants. 

P = the aggregate price per share of the additional shares. 

M = the Fair Value per share of Common Stock on the record date. 

The adjustment shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately
after the record date for the determination of stockholders entitled to receive the rights, options or warrants. If at the end of the period during which such rights, options or warrants are exercisable, not all rights, options or warrants shall
have been exercised, the Exercise Price shall be immediately readjusted to what it would have been if “N” in the above formula had been the number of shares actually issued. 

(c) Adjustment for Other Distributions. 

  
 18 








Table of Contents



 If the Company distributes to all holders of its Common Stock any of its assets or debt
securities or any rights or warrants to purchase debt securities of the Company, the Exercise Price shall be adjusted in accordance with the formula: 
  





 
 where: 
  

			
	E’ =	  	the adjusted Exercise Price.
		
	E =	  	the then current Exercise Price.
		
	M =	  	the Fair Value per share of Common Stock on the record date mentioned below.
		
	F =	  	the fair market value on the record date of the assets, securities, rights or warrants to be distributed in respect of one share of Common Stock as determined in good faith by
the Board of Directors.

 The adjustment shall be made successively whenever any such distribution is made and shall become
effective immediately after the record date for the determination of stockholders entitled to receive the distribution. 
 This
Section 6.01(c) does not apply to rights, options or warrants referred to in Section 6.01(b) hereof. 
 (d)
Adjustment for Common Stock Issue. 
 If the Company issues shares of Common Stock for a consideration per share less
than the Fair Value per share on the date the Company fixes the offering price of such additional shares, the Exercise Price shall be adjusted in accordance with the formula: 

 
 



 
 where: 
  

			
	E’ =	  	the adjusted Exercise Price.
		
	E =	  	the then current Exercise Price.
		
	O =	  	the number of shares outstanding immediately prior to the issuance of such additional shares.


  
 19 








Table of Contents




			
	P =	  	the aggregate consideration received for the issuance of such additional shares.
		
	M =	  	the Fair Value per share on the date of issuance of such additional shares.
		
	A =	  	the number of shares outstanding immediately after the issuance of such additional shares.

 The adjustment shall be made successively whenever any such issuance is made, and shall become effective
immediately after such issuance. 
 This subsection (d) does not apply to: 

(i) any of the transactions described in subsections (a), (b) and (c) of this Section 6.01, 

(ii) the exercise of Warrants, or the conversion or exchange of other securities convertible or exchangeable for Common
Stock, which are the subject of Section 6.01(e), 
 (iii) shares of Common Stock issued in a merger of the
Company with a Person who is not an Affiliate of the Company; and 
 (iv) shares of Common Stock issued pursuant
to, or upon the exercise of awards granted pursuant to, employee benefit plans of the Company in an aggregate amount not to exceed, together with Common Stock issuable pursuant to Section 6.01(e)(iii), 10% of the outstanding shares of Common
Stock of the Company on the date of this Agreement on a fully-diluted basis after giving effect to the issuance of the Warrants, subject to any applicable anti-dilution adjustment. 

(e) Adjustment for Convertible Securities Issue. 
 If the Company issues any securities convertible into or exchangeable for Common Stock (other than (x) securities issued in transactions described in subsections (b) or (c) or (y) the
Warrants) for a consideration per share of Common Stock received for such securities that is less than the Fair Value per share on the date the Company fixes the offering price of such securities, the Exercise Price shall be adjusted in accordance
with this formula: 
  
 



 
 where: 
  

			
	E’ =	  	the adjusted Exercise Price.
		
	E =	  	the then current Exercise Price.


  
 20 








Table of Contents




			
	O =	  	the number of shares outstanding immediately prior to the issuance of such securities.
		
	P =	  	the aggregate consideration received for such securities.
		
	M =	  	the Fair Value per share on the date of issuance of such securities.
		
	D =	  	the maximum number of shares deliverable upon conversion or in exchange for such securities at the initial conversion or exchange rate.

 The adjustment shall be made successively whenever any such issuance is made, and shall become effective
immediately after such issuance. 
 If all of the Common Stock deliverable upon conversion or exchange of such securities have
not been issued when such securities are no longer outstanding, then the Exercise Price shall promptly be readjusted to the Exercise Price which would then be in effect had the adjustment upon the issuance of such securities been made on the basis
of the actual number of shares of Common Stock issued upon conversion or exchange of such securities. 
 This
subsection (e) does not apply to 
 (i) convertible or exchangeable securities issued in a merger of the
Company with a Person who is not an Affiliate of the Company; 
 (ii) convertible or exchangeable securities
issued as consideration in a merger of the Company with any of its Affiliates, if the Company obtains an opinion from a nationally recognized investment banking, appraisal or valuation firm stating that the consideration received in such merger is
fair to the Company; 
 (iii) securities issued pursuant to employee benefit plans of the Company convertible
into an aggregate number of shares of Common Stock not to exceed (together with shares issued pursuant to clause (d)(iv) above under employee benefit plans of the Company) 10% of the outstanding shares of Common Stock of the Company on the date of
this Agreement on a fully-diluted basis after giving effect to the issuance of the Warrants, subject to any applicable anti-dilution adjustment. 
 (f) Consideration Received. 
 For purposes of any computation respecting
consideration received pursuant to subsections (d) and (e) of this Section 6.01, the following shall apply: 
 (i) in the case of the issuance of shares of Common Stock for cash, the consideration shall be the amount of such cash, provided that in no case shall any deduction be made for any commissions,
discounts or other expenses incurred by the Company for any underwriting of the issue or otherwise in connection therewith; 

  
 21 








Table of Contents



 (ii) in the case of the issuance of shares of Common Stock for a
consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors and described in a Board Resolution (and, if such issuance
is to an Affiliate of the Company, approved by a majority of the Disinterested Directors or confirmed by a written opinion of a nationally recognized investment banking, appraisal of valuation firm that is not an Affiliate of the Company);

 (iii) in the case of the issuance of securities convertible into or exchangeable for shares of Common Stock,
the aggregate consideration received therefor shall be deemed to be the consideration received by the Company for the issuance of such securities plus the additional minimum consideration, if any, to be received by the Company upon the conversion or
exchange thereof (the consideration in each case to be determined in the same manner as provided in clauses (i) and (ii) of this subsection); and 
 (iv) in the case of the issuance of shares of Common Stock pursuant to rights, options or warrants which rights, options or warrants were originally issued together with one or more other securities as
part of a unit at a price per unit, the consideration shall be deemed to be the fair value of such rights, options or warrants at the time of issuance thereof as determined in good faith by the Board of Directors in accordance with GAAP whose
determination shall be described in a Board Resolution (and, if such issuance is to an Affiliate of the Company, approved by a majority of the Disinterested Directors or confirmed by a written opinion of a nationally recognized investment banking,
appraisal of valuation firm that is not an Affiliate of the Company) plus the additional minimum consideration, if any, to be received by the Company upon the exercise, conversion or exchange thereof (as determined in the same manner as
provided in clauses (i) and (ii) of this subsection). 
 (g) Fair Value. The “Fair Value” per
security at any date of determination shall be (x) in connection with a sale to a party that is not an Affiliate of the Company in an arm’s-length transaction (a “Non-Affiliate Sale”), the price per security at which such
security is sold, and (y) in connection with any sale to an Affiliate of the Company, (1) if shares of the applicable class of Common Stock are then quoted by any national securities exchange, the average (weighted by daily trading volume)
of the Daily Prices per share of the applicable class of Common Stock for the 20 consecutive trading days immediately prior to such date, or (2) if shares of the applicable class of Common Stock are not then quoted by any national securities
exchange: 
 (a) the last price per security at which such security was sold in a Non-Affiliate Sale within the three-month
period ending on such date of determination or 
 (b) if clause (a) is not applicable, the fair market value of such
security determined in good faith by

Table of Contents



 (i) a majority of the Board of Directors of the Company, including a
majority of the Disinterested Directors, and approved in a board resolution delivered to the Warrant Agent or 

(ii) a nationally recognized investment banking, appraisal or valuation firm, which is not an Affiliate of the Company,
in each case, taking into account, among all other factors deemed relevant by the Board of Directors or the investment banking, appraisal or valuation firm, the trading price and volume of such security on any national securities exchange or
automated quotation system on which such security is traded. 
 (h) When De Minimis Adjustment May Be Deferred.

 No adjustment in the Exercise Price need be made unless the adjustment would require an increase or decrease of at least 1%
in the Exercise Price. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 6.01 shall be made to the nearest cent or to the nearest 1/10,000th of a
share, as the case may be, it being understood that no such rounding shall be made under subsection (n) (and, in calculations made pursuant to such paragraph, the adjusted Exercise Price shall refer to such adjusted price before rounding).

 (i) When No Adjustment Required. 
 No adjustment need be made for a transaction referred to in Section 6.01(a), (b), (c), (d) or (e) hereof, if Holders are to participate (without being required to exercise their Warrants)
in the transaction on a basis and with notice that the Board of Directors determines to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. No adjustment need be made for
(i) rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest, or (ii) a change in the par value or no par value of the Common Stock. To the extent the Warrants become convertible into cash, no
adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. 
 (j) Notice of Adjustment.

 Whenever the Exercise Price is adjusted, the Company shall provide the notices required by Section 6.03 hereof.

 (k) Reorganization of Company. 
 If the Company consolidates or merges with or into, or transfers or leases all or substantially all its assets to, any Person, upon consummation of such transaction the Warrants shall automatically become
exercisable for the kind and amount of securities, cash or other assets which the Holder of a Warrant would have owned immediately after the consolidation, merger, transfer or lease if the Holder had exercised the Warrant immediately before the
effective date of the transaction. Concurrently with the consummation of such transaction, the Person formed by or surviving any such consolidation or merger if other than the Company, or the Person to which


  
 23 








Table of Contents



 
such transfer or lease shall have been made, shall enter into a supplemental Agreement so providing and further providing for adjustments which shall be as nearly equivalent as may be practical
to the adjustments provided for in this Section 6.01. The successor Company shall mail to Warrant Holders a notice describing the supplemental Agreement. If the issuer of securities deliverable upon exercise of Warrants under the supplemental
Agreement is an Affiliate of the formed, surviving, transferee or lessee person, that issuer shall join in the supplemental Agreement. If this Section 6.01(k) applies to a transaction, Section 6.01(a),(b), (c), (d) and (e) hereof
do not apply. 
 (l) Company Determination Final. 

Any determination that the Company or the Board of Directors must make pursuant to Section 6.01(a) through (i) hereof is
conclusive in the absence of manifest error or bad faith. 
 (m) When Issuance or Payment May Be Deferred. 

In any case in which this Section 6.01 shall require that an adjustment in the Exercise Price be made effective as of a record date
for a specified event, the Company may elect to defer until the occurrence of such event (i) issuing to the holder of any Warrant exercised after such record date the Warrant Shares and other capital stock of the Company, if any, issuable upon
such exercise over and above the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise on the basis of the Exercise Price and (ii) paying to such holder any amount in cash in lieu of a fractional share
pursuant to Section 6.02 hereof; provided that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional Warrant Shares, other capital stock and
cash upon the occurrence of the event requiring such adjustment. 
 (n) Adjustment in Number of Shares. 

Upon each adjustment of the Exercise Price pursuant to this Section 6.01, each Warrant outstanding prior to the making of the
adjustment in the Exercise Price shall thereafter evidence the right to receive upon payment of the adjusted Exercise Price that number of shares of Common Stock (calculated to the nearest hundredth) obtained from the following formula: 

 
 



 
 where: 
  

			
	N’ =	  	the adjusted number of Warrant Shares issuable upon exercise of a Warrant by payment of the adjusted Exercise Price.
		
	N =	  	the number of Warrant Shares previously issuable upon exercise of a Warrant by payment of the Exercise Price prior to adjustment.
		
	E’ =	  	the adjusted Exercise Price.


  
 24 








Table of Contents



 E    =    the Exercise Price prior
to adjustment. 
  

	 	(o)	Form of Warrants. 


Irrespective of any adjustments in the Exercise Price or the number or kind of shares purchasable upon the exercise of the Warrants,
Warrants theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the Warrants initially issuable pursuant to this Agreement. 

 

	 	(p)	No Adjustment Below Par Value. 

 Notwithstanding anything herein to the contrary, no adjustment will be made to the Exercise Price if, as a result of such adjustment, the Exercise Price per Warrant Share would be less than the par value
of the Company’s Common Stock (or other capital stock for which any Warrant is exercisable); provided that, before taking any action which would but for the foregoing limitation in this sentence have caused an adjustment to reduce the
Exercise Price below the then par value (if any) of its Common Stock (or other capital stock for which any Warrant is exercisable), the Company will take any corporate action which would, in the opinion of its counsel, be necessary in order that the
Company may validly issue Warrant Shares at the Exercise Price as so adjusted. 
 Section 6.02. Fractional Interests. The
Company shall not be required to issue fractional Warrant Shares or scrip representing fractional shares on the exercise of Warrants. If more than one Warrant shall be presented for exercise in full at the same time by the same Holder, the number of
full Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares purchasable on exercise of the Warrants so presented. If any fraction of a Warrant Share would, except for
the provisions of this Section 6.02, be issuable on the exercise of any Warrants (or specified portion thereof), the Company shall pay an amount in cash equal to the current Daily Price per Warrant Share, as determined on the date the Warrant
is presented for exercise, multiplied by such fraction, computed to the nearest whole U.S. cent. 
 Section 6.03. Notices To
Warrant Holders. (a) Upon any adjustment of the Exercise Price pursuant to Section 6.01 hereof, the Company shall promptly thereafter (i) cause to be filed with the Warrant Agent a certificate of a firm of independent public
accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Exercise Price after such adjustment and setting forth in reasonable detail the method of calculation and the
facts upon which such calculations are based and setting forth the number of Warrant Shares (or portion thereof) or other securities or property issuable after such adjustment in the Exercise Price, upon exercise of a Warrant and payment of the
adjusted Exercise Price, which certificate shall be conclusive evidence of the correctness of the matters set forth therein, and (ii) cause to be given to each of the Holders written notice of such adjustments by first-class mail, postage
prepaid. Where appropriate, such notice may be given in advance and included as a part of the notice required to be mailed under the other provisions of this Section 6.03.

 (b) In case: 

(i) the Company shall authorize the issuance to all holders of shares of Common Stock of rights, options or warrants to
subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; 
 (ii) the
Company shall authorize the distribution to all holders of shares of Common Stock of evidences of its indebtedness or assets (other than dividends or distributions referred to in Section 6.01(a) hereof); 

(iii) of any consolidation or merger to which the Company is a party, or of the transfer or lease of all or substantially
all assets of the Company, or of any reclassification or change of Common Stock issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a
subdivision or combination), or a tender offer or exchange offer for shares of Common Stock by the Company; 

(iv) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or 

(v) the Company proposes to take any action which would require an adjustment of the Exercise Price pursuant to
Section 6.01 hereof; 
 then the Company shall cause to be filed with the Warrant Agent and shall cause to be given to each of the Holders,
at least 20 days (or 10 days in any case specified in clauses (i) or (ii) above) prior to any applicable record date, or promptly in the case of events for which there is no record date, by first-class mail, postage prepaid, a written
notice stating (x) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such rights, options, warrants or distribution are to be determined, (y) the initial expiration date set forth in any
tender offer or exchange offer for shares of Common Stock, or (z) the date on which any such consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up is expected to become effective or consummated, and the date as of
which it is expected that holders of record of shares of Common Stock shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such reclassification, consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding up. The failure to give the notice required by this Section 6.03 or any defect therein shall not affect the legality or validity of any distribution, right, option, warrant, consolidation, merger, conveyance,
transfer, dissolution, liquidation or winding up, or the vote upon any action. 
 Section 6.04 . No Rights As Stockholders.
Nothing contained in this Agreement or the Warrants shall be construed as conferring upon the holders of Warrants the right to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of
directors of the Company or any other matter, or any rights whatsoever, including the right to receive dividends, as stockholders of the Company, or the right to share in the assets of the Company in the event of its liquidation, dissolution or
winding up.

of any securities or assets issued upon exercise of Warrants. 
 (c) The Warrant Agent shall not be accountable with respect to
the validity or value or the kind or amount of any Warrant Shares or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or with respect to whether any such Warrant Shares or other securities
will, when issued, be validly issued and fully paid and nonassessable, and makes no representation with respect thereto. 
 (d)
The Warrant Agent shall not be responsible for any failure of the Company to comply with any of the covenants contained in this Agreement or in the Warrants. 
 (e) In the absence of bad faith on its part, the Warrant Agent may rely, and will be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Warrant Agent need not
investigate any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the Warrant Agent pursuant to any provision hereof, the Warrant Agent shall examine the document to determine
whether it conforms to the requirements of this Agreement (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). The Warrant Agent, in its discretion, may make further inquiry or investigation
into such facts or matters as it sees fit.

action, its own negligent failure to act, or its own willful misconduct, except that this paragraph does not limit the effect of Section 7.01(e).

Table of Contents



 (h) The Warrant Agent shall not be subject to any fiduciary or other implied duties of any
kind or nature and its sole obligations shall be to comply with the terms contained in this Agreement. 
 (i) The Warrant Agent
may consult with counsel, and the written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon. 
 (j) No provision of this Agreement will require the Warrant Agent to expend or risk its own funds or otherwise incur
any financial liability in the performance of its duties hereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense. 

(k) The Warrant Agent shall act hereunder solely as agent for the Company, and its duties shall be determined solely by the provisions
hereof. No provision of this Agreement shall be construed to relieve the Warrant Agent from liability for its own negligent action, its own negligent failure to act or its own willful misconduct. 

Section 7.02. Compensation; Indemnity. (a) The Company will pay the Warrant Agent compensation as agreed upon
in writing for its services. The Company will reimburse the Warrant Agent upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Warrant Agent, except any such expense, disbursement or advance
attributable to its negligence or bad faith. Such expenses shall include the reasonable compensation and expenses of the Warrant Agent’s agents and counsel.

upon it or any of its officers in connection with the exercise or performance of any of its powers or duties under this Agreement and the Warrants, except to the extent any such loss, liability or expense may be attributable to its negligence or
willful misconduct. The Warrant Agent shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Warrant Agent to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall
defend the claim and the Warrant Agent shall cooperate in the defense at the Company’s expense. The Warrant Agent may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for
any settlement made without its consent, which consent shall not be unreasonably withheld.

the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity. An Agent may do the same with like rights.

association, the resulting, surviving or transferee corporation or national banking association without any further act will be the successor Warrant Agent with the same effect as if the successor Warrant Agent had been named as the Warrant Agent in

(a) Any notice, consent to amendment, supplement or waiver provided by this Agreement to be given by a Holder (an “act”) may be evidenced by an instrument signed by the Holder delivered to the Warrant Agent.

 (b) Any act by the Holder of any Warrant binds that Holder and every subsequent Holder of a Warrant certificate that
evidences the same Warrant of the acting Holder, even if no notation thereof appears on the Warrant certificate. Subject to paragraph (c), a Holder may revoke an act as to its Warrants, but only if the Warrant Agent receives the notice of revocation
before the date the amendment or waiver or other consequence of the act becomes effective.

 (c) The Company may, but is not obligated to, fix a record date for the purpose of
determining the Holders entitled to act with respect to any amendment or waiver or in any other regard. If a record date is fixed, those Persons that were Holders at such record date and only those Persons will be entitled to act, or to revoke any
previous act, whether or not those Persons continue to be Holders after the record date. No act will be valid or effective for more than 90 days after the record date. 
 Section 8.02. Notices. (a) Any notice or communication by the Company, on the one hand, or the Warrant Agent, on the other hand, to the other is duly given if in writing (i) when

communication to a Holder, if given by the Company, will be mailed to the Warrant Agent at the same time. Defect in mailing a notice or communication to any particular Holder will not affect its sufficiency with respect to other Holders. 


  
 31 








Table of Contents



 (c) Where this Agreement provides for notice, the notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and the waiver will be the equivalent of the notice. Waivers of notice by Holders must be filed with the Warrant Agent, but such filing is not a condition precedent to the
validity of any action taken in reliance upon such waivers. 
 Section 8.03 . Supplements And Amendments.
(a) The Company and the Warrant Agent may amend or supplement this Agreement or the Warrants without notice to or the consent of any Holder 
 (i) to cure any ambiguity, defect or inconsistency in this Agreement or the Warrants; 
 (ii) to comply with Section 6.01(k); 
 (iii) to evidence and
provide for the acceptance of an appointment hereunder by a successor Warrant Agent; or 
 (iv) to make any other
change that does not adversely affect the rights of any Holder. 
 (b) Except as otherwise provided in paragraphs (a) or
(c), the Company and the Warrant Agent may amend this Agreement and the Warrants with the written consent of the Holders of a majority of the outstanding Warrants, and the Holders of a majority of the outstanding Warrants by written notice to the
Warrant Agent may waive future compliance by the Company with any provision of this Agreement or the Warrants. In addition, any term of a specific Warrant may be amended or waived with the written consent of the Company and the Holder of such
Warrant. 
 (c) Notwithstanding the provisions of paragraph (b), without the consent of each Holder affected, an amendment or
waiver may not 
 (i) increase the Exercise Price; or 

(ii) decrease the number of shares of Common Stock or other securities or property issuable upon exercise of the Warrants

 except, in each case, for adjustments provided for in this Agreement. 

(d) It is not necessary for Holders to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if
their consent approves the substance thereof. 

  
 32 








Table of Contents



 (e) An amendment, supplement or waiver under this Section will become effective on receipt
by the Warrant Agent of written consents from the Holders of the requisite percentage of the outstanding Warrants. After an amendment, supplement or waiver under this Section becomes effective, the Company will send to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

 (f) After an amendment, supplement or waiver becomes effective, it will bind every Holder unless it is of the type requiring
the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder
of a Warrant with respect to which consent was granted. 
 (g) If an amendment, supplement or waiver changes the terms of a
Warrant, the Company or the Warrant Agent may require the Holder to deliver it to the Warrant Agent so that the Warrant Agent may place an appropriate notation of the changed terms on the Warrant and return it to the Holder, or exchange it for a new
Warrant that reflects the changed terms. The Warrant Agent may also place an appropriate notation on any Warrant thereafter countersigned. However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate
or exchange Warrants in this fashion. 
 (h) The Warrant Agent is entitled to receive, and will be fully protected in relying
upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this section is authorized or permitted by this Agreement. If the Warrant Agent has received such an Opinion of Counsel, it shall
sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Warrant Agent. The Warrant Agent may, but is not obligated to, execute any amendment, supplement or waiver that affects the Warrant Agent’s
own rights, duties or immunities under this Agreement. 
 Section 8.04 . Governing Law. This Agreement and the Warrants
shall be governed by, and construed in accordance with, the laws of the State of New York. 
 Section 8.05 . No
Adverse Interpretation of Other Agreements. This Agreement may not be used to interpret another agreement of the Company, and no such agreement may be used to interpret this Agreement. 

Section 8.06 . Successors. All agreements of the Company in this Agreement and the Warrants will bind its successors. All
agreements of the Warrant Agent in this Agreement will bind its successors. 
 Section 8.07 . Duplicate Originals.
The parties may sign any number of copies of this Agreement. Each signed copy shall be an original, but all of them together represent the same agreement. 
 Section 8.08 . Separability. In case any provision in this Agreement or in the Warrants is invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions will not in any way be affected or impaired thereby.

Warrant Agent and the registered holders of Warrants.

 GREEN FIELD ENERGY SERVICES,
INC. 
 [Reverse of Warrant Certificate] 
 1. Warrant Agreement 
 The Warrants evidenced by this Warrant
Certificate are part of a duly authorized issue of Warrants issued or to be issued pursuant to a Warrant Agreement dated as of November 15, 2011 (the “Warrant Agreement”), between the Company and Wilmington Trust, National
Association, as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the registered holders or registered holder) of the Warrants. To the extent
permitted by law, in the event of an inconsistency or conflict between the terms of this Warrant and the Warrant Agreement, the terms of the Warrant Agreement will prevail. 
 2. Exercise 
 Warrants may be exercised at any time on or after the
Separation Date (as defined in the Warrant Agreement) and on or before 5:00 p.m. New York City time on the Expiration Date; provided that holders shall be able to exercise their Warrants only if the exercise of such Warrants is exempt from,
or in compliance with, the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), and such securities are qualified for sale or exempt from qualification under the applicable securities laws of
the states in which the various holders of the Warrants or other persons to whom it is proposed that the Warrant Shares be issued on exercise of the Warrants reside. In order to exercise all or any of the Warrants represented by this Warrant
Certificate, the holder must deliver to the Warrant Agent at its Corporate Trust Office set forth in the Warrant Agreement this Warrant Certificate and the form of election to purchase on the reverse hereof duly completed, which signature shall be
medallion guaranteed by an institution which is a member of a Securities Transfer Association recognized signature guarantee program, and upon payment to the Warrant Agent for the account of the Company of the Exercise Price in the manner set forth
in the Warrant Agreement for the number of Warrant Shares in respect of which such Warrants are then exercised. 
 No Warrant
may be exercised after 5:00 p.m., New York City time, on the Expiration Date, and to the extent not exercised by such time the Warrants shall become void. 
 3. Adjustments 
 The Warrant Agreement provides that, upon the
occurrence of certain events, the Exercise Price set forth on the face hereof may, subject to certain conditions, be adjusted. The Warrant Agreement also provides that the number of shares of Common Stock issuable upon the exercise of each Warrant
shall be adjusted in certain events. 

  
 A-4








Table of Contents



 4. No Fractional Shares. 

No fractions of a share of Common Stock will be issued upon the exercise of any Warrant, but the Company will pay the cash value thereof
determined as provided in the Warrant Agreement. 
 5. Registration Rights. 

In addition to the rights provided to Holders under the Warrant Agreement, Holders of Registrable Securities (as defined in the Equity
Registration Rights Agreement) shall have all the rights set forth in the Equity Registration Rights Agreement, dated as of the date of the Warrant Agreement, among the Company and the Initial Purchaser, as such agreement may be amended, modified or
supplemented from time to time. 
 6. Registered Form; Transfer and Exchange. 

The Warrants are in registered form. Warrant Certificates, when surrendered at the office of the Warrant Agent by the registered holder
thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge (except as specified in
the Warrant Agreement), for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 
 Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed
