 SECOND AMENDED AND RESTATED 
 RIGHTS AGREEMENT 
  
 This Rights Agreement, dated as of January 31, 1997 as amended and restated as of June 17, 1999 and as further amended and restated as of October 24, 2004 (the “Agreement”), between Syntroleum Corporation, a
Delaware corporation (the “Company”), and American Stock Transfer & Trust Company (the “Rights Agent”), 
  
 W I T N E S S E T H: 
  
 Syntroleum Corporation, a Kansas corporation formerly named SLH Corporation (“Syntroleum-Kansas”), and the Rights
Agent entered into a Rights Agreement dated as of January 31, 1997 (the “Original Rights Agreement”). The Board of Directors of Syntroleum-Kansas authorized and declared a dividend of one preferred share purchase right (a “Predecessor
Right”) for each Common Share (as defined in the Original Rights Agreement) of Syntroleum-Kansas outstanding as of the close of business on February 24, 1997 (the “Record Date”), each Predecessor Right originally representing the
right to purchase one one-hundredth of a Preferred Share (as defined in the Original Rights Agreement), upon the terms and subject to the conditions set forth in the Original Rights Agreement, and further authorized and directed the issuance of one
Predecessor Right with respect to each Common Share that shall become outstanding between the Record Date and the earliest of the Distribution Date, the Redemption Date and the Final Expiration Date (as such terms are defined in the Original Rights
Agreement). 
  
 On July 21, 1997, Syntroleum-Kansas effected a
three-for-one split of its Common Shares, and on February 9, 1998, Syntroleum-Kansas effected a two-for-one split of its Common Shares (collectively, the “Stock Splits”), resulting in an adjustment to the Predecessor Rights to represent
the right to purchase one-sixth of one one-hundredth of a Preferred Share (as defined in the Original Rights Agreement). 
  
 Syntroleum-Kansas and the Rights Agent entered into an Amendment to Rights Agreement dated as of March 30, 1998 and a Second Amendment to Rights Agreement
dated as of August 7, 1998 (collectively, the “Rights Agreement Amendments”) to amend Section 1(a) thereof to provide that neither Kenneth L. Agee, nor Mark A. Agee, nor members of their immediate families, nor any of their Affiliates or
Associates, individually or collectively, shall be deemed an Acquiring Person. 
  
 The Company, pursuant to an agreement dated June 17, 1999 (the “First Restated Rights Agreement”), amended and restated the Original Rights Agreement to reflect the Stock Splits, the Rights Agreement
Amendments and the following transactions: 
  
 Syntroleum-Kansas
and the Company were parties to an Agreement and Plan of Merger (the “Merger Agreement”) dated as of May 7, 1999, pursuant to which (i) Syntroleum-Kansas would be merged with and into the Company, (ii) the Company would be the surviving
corporation, (iii) each outstanding Common Share of Syntroleum-Kansas would be converted into the right to receive one Common Share (as defined in the First Restated Rights Agreement) of the Company in accordance with and pursuant to the terms and
conditions set forth in the Merger Agreement, (iv) the Original Rights Agreement, as amended, would be assumed by the 
  

 1 

 Company and amended and restated to effect such assumption and (v) each Predecessor Right would be converted into and
become a preferred share purchase right representing the right to purchase one-sixth of one one-hundredth of a Preferred Share (as defined in the First Restated Rights Agreement). The Board of Directors of the Company authorized and directed the
issuance of one Right with respect to each Common Share that shall become outstanding between the Effective Time and the earliest of the Distribution Date, the Redemption Date and the Final Expiration Date (as such terms are defined in the First
Restated Rights Agreement). 
  
 On October 31, 2003, the Company
and the Rights Agent entered into a First Amendment to the Amended and Restated Rights Agreement to amend Section 1(a) thereof to provide that neither Robert A. Day nor members of his immediate family, nor any of their Affiliates or Associates,
individually or collectively, shall be deemed an Acquiring Person unless Robert A. Day or any member of his immediate family, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner of 35% or more of the Common
Shares of the Company then outstanding, and to effect related changes. 
  
 WHEREAS, the Company desires to make certain amendments to the terms of the First Restated Rights Agreement and to restate the Agreement; 
  
 WHEREAS, on October 24, 2004, the Board of Directors of the Company authorized the issuance of one Right (as such number may hereinafter be adjusted
pursuant to the provisions of Section 11(p) hereof) for each share of Common Stock of the Company issued (whether originally issued or delivered from the Company’s treasury) between the date hereof and the earlier of the Distribution Date (as
hereinafter defined) and the Expiration Date (as hereinafter defined), and, in certain circumstances provided for in Section 22 hereof, after the Distribution Date, each Right initially representing the right to purchase one Fractional Share (as
hereinafter defined) of Series A Junior Participating Preferred Stock of the Company, upon the terms and subject to the conditions hereinafter set forth (the “Rights”); 
  
 NOW, THEREFORE, in consideration of the premises and the mutual agreements herein set forth, the parties hereby agree as
follows: 
  
 Section 1. Certain Definitions. For purposes
of this Agreement, the following terms shall have the meanings indicated: 
  
 “Acquiring Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner of 20% or more of the shares of Common Stock then outstanding,
but shall not include any Exempt Person; provided, however, that a Person shall not be or become an Acquiring Person if such Person, together with its Affiliates and Associates, shall become the Beneficial Owner of 20% or more of the shares
of Common Stock then outstanding solely as a result of a reduction in the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company, unless and until such time as such Person together with its Affiliates and
Associates shall purchase or otherwise become the Beneficial Owner of additional shares of Common Stock constituting 1% or more of the then outstanding shares of Common Stock or any other Person (or Persons) who is (or collectively are) the
Beneficial Owner of shares of Common Stock constituting 1% or more of the then outstanding shares of Common Stock shall become an Affiliate or Associate of such 
  

 2 

 Person, unless, in either such case, such Person, together with all Affiliates and Associates of such Person, is not then
the Beneficial Owner of 20% or more of the shares of Common Stock then outstanding; and provided, further, that if the Board of Directors determines in good faith that a Person that would otherwise be an “Acquiring Person” has
become such inadvertently (including, without limitation, because (i) such Person was unaware that it beneficially owned a percentage of Common Stock that would otherwise cause such Person to be an “Acquiring Person” or (ii) such Person
was aware of the extent of its Beneficial Ownership of Common Stock but had no actual knowledge of the consequences of such Beneficial Ownership under this Agreement) and without any intention of changing control of the Company, and if such Person
as promptly as practicable divested or divests itself of Beneficial Ownership of a sufficient number of shares of Common Stock so that such Person would no longer be an “Acquiring Person,” then such Person shall not be deemed to be or to
have become an “Acquiring Person” for any purposes of this Agreement. 
  
 Notwithstanding anything in this definition of “Acquiring Person” to the contrary, Robert A. Day, members of his immediate family and any Affiliate or Associate thereof individually or collectively (the
“Day Parties”) shall not be or become an Acquiring Person unless and until the Day Parties become the Beneficial Owner of 35% or more of the shares of Common Stock then outstanding; provided, however, that the Day Parties shall not become
an Acquiring Person if the Day Parties shall become the Beneficial Owner of 35% or more of the shares of Common Stock then outstanding solely as a result of a reduction in the number of shares of Common Stock outstanding due to the repurchase of
Common Stock by the Company, unless and until such time as the Day Parties shall purchase or otherwise become the Beneficial Owner of additional shares of Common Stock constituting 1% or more of the then outstanding shares of Common Stock or any
other Person (or Persons) who is (or collectively are) the Beneficial Owner of shares of Common Stock constituting 1% or more of the then outstanding shares of Common Stock shall become an Affiliate or Associate of the Day Parties. 
  
 At any time that the Rights are redeemable, the Board of Directors may,
generally or with respect to any specified Person or Persons, determine to increase to a specified percentage or amount greater than that set forth herein or decrease to a specified percentage or amount lower than that set forth herein or determine
a number of shares to be (but in no event less than or equal to the percentage or number of shares of Common Stock then beneficially owned by such Person), the level of Beneficial Ownership of Common Stock at which a Person or such Person or Persons
becomes an Acquiring Person. 
  
 “Adjustment Shares”
shall have the meaning set forth in Section 11(a)(ii) hereof. 
  
 “Affiliate” shall have the meaning ascribed to such term in Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in effect on the date of this Agreement.

corporation, firm, partnership, association, unincorporated organization or other entity (other than the Company or a Subsidiary of the Company) of which such Person is an officer or general partner (or officer or general partner of a general
partner) or is, directly or indirectly, the Beneficial Owner of 10% or more of any class of equity securities, (2) any trust or other estate in which such Person has a 
  

 3 

 substantial beneficial interest or as to which such Person serves as trustee or in a similar fiduciary capacity and (3)
any relative or spouse of such Person, or any relative of such spouse, who has the same home as such Person. 
  
 A Person shall be deemed the “Beneficial Owner” of, and shall be deemed to “beneficially own,” any securities: 
  
 (i) that such Person or any of such Person’s Affiliates
or Associates, directly or indirectly, is the “beneficial owner” of (as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Exchange Act as in effect on the date of this Agreement) or otherwise has the right to
vote or dispose of, including pursuant to any agreement, arrangement or understanding (whether or not in writing); provided, however, that a Person shall not be deemed the “Beneficial Owner” of, or to “beneficially own,”
any security under this subparagraph (i) as a result of an agreement, arrangement or understanding to vote such security if such agreement, arrangement or understanding: (A) arises solely from a revocable proxy or consent given in response to a
public (i.e., not including a solicitation exempted by Rule 14a-2(b)(2) of the General Rules and Regulations under the Exchange Act as in effect on the date of this Agreement) proxy or consent solicitation made pursuant to, and in accordance
with, the applicable provisions of the General Rules and Regulations under the Exchange Act, (B) is not then reportable by such Person on Schedule 13D under the Exchange Act (or any comparable or successor report) and (C) does not constitute a
trust, proxy, power of attorney or other device with the purpose or effect of allowing two or more persons, acting in concert, to avoid being deemed “beneficial owners” of such security or otherwise avoid the status of “Acquiring
Person” under the terms of this Agreement or as part of a plan or scheme to evade the reporting requirements under Schedule 13D or Sections 13(d) or 13(g) of the Exchange Act; 
  
 (ii) that such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the
right or obligation to acquire (whether such right or obligation is exercisable or effective immediately or only after the passage of time or the occurrence of an event) pursuant to any agreement, arrangement or understanding (whether or not in
writing) or upon the exercise of conversion rights, exchange rights, other rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the “Beneficial Owner” of, or to “beneficially
own,” (A) securities tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange, (B) securities issuable upon
exercise of Rights at any time prior to the occurrence of a Triggering Event, or (C) securities issuable upon exercise of Rights from and after the occurrence of a Triggering Event which Rights were acquired by such Person or any of such
Person’s Affiliates or Associates prior to the Distribution Date or pursuant to Section 3(a) or Section 22 hereof (the “Original Rights”) or pursuant to Section 11(i) or (p) hereof in connection with an adjustment made with respect to
any Original Rights; or 
  
 (iii) that are

 4 

 in writing) for the purpose of acquiring, holding, voting (except pursuant to a revocable proxy or
consent as described in the proviso to subparagraph (i) of this definition) or disposing of any voting securities of the Company or (B) any group (as that term is used in Rule 13d-5(b) of the General Rules and Regulations under the Exchange Act, as
in effect on the date of this Agreement) of which such Person is a member; 
  
 provided, however, that nothing in this definition shall cause a Person engaged in business as an underwriter of securities to be the “Beneficial Owner” of, or to “beneficially own,” any securities acquired
through such Person’s participation in good faith in a firm commitment underwriting (including, without limitation, securities acquired pursuant to stabilizing transactions to facilitate a public offering in accordance with Regulation M
promulgated under the Exchange Act, or to cover overallotments created in connection with a public offering) until the expiration of forty days after the date of such acquisition. For purposes of this Agreement, “voting” a security shall
include voting, granting a proxy, acting by consent, making a request or demand relating to corporate action (including, without limitation, calling a stockholder meeting), entering into a voting trust or voting agreement or otherwise giving an

is listed or admitted to trading, or, if such security is not listed or admitted to trading on any national securities exchange but sales price information is reported for such security, as reported by NASDAQ or such other self-regulatory

low asked prices in the over-the-counter market on such day, as reported by NASDAQ or such other entity, or, if on such day such security is not quoted by any such entity, the average of the closing bid and asked prices as furnished by a

the Expiration Date, the transfer of any of the certificates for Common Stock outstanding on the Record Date, with or without a copy of the Summary of Rights, shall also constitute the transfer of the Rights associated with the Common Stock
represented by such certificates. 
  
 (c) Rights have been and
shall be issued in respect of all shares of Common Stock that have been issued (whether originally issued or delivered from the Company’s treasury) after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date
or, in certain circumstances provided in Section 22 hereof, after the Distribution Date.

set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. Syntroleum Corporation will mail to the holder of this certificate a copy of the Rights Agreement without
charge after receipt of a written request therefor. Under certain circumstances, as set forth in the Rights Agreement, Rights issued to any Person who becomes an Acquiring Person (as defined in the Rights Agreement) may become null and void.

  
 With respect to such certificates containing the foregoing legend, until the
earlier of the Distribution Date or the Expiration Date, the Rights associated with the Common Stock represented by such certificates shall be evidenced by such certificates alone, and registered holders of Common Stock shall also be the registered
holders of the associated Rights, and the transfer of any of such certificates shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificates. 
  
 Section 4. Form of Rights Certificates. 
  
 (a) The Rights Certificates (and the forms of election to purchase and of
assignment to be printed on the reverse thereof), when, as and if issued, shall be substantially in the form set forth in Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed
thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any stock exchange or quotation system on which the Rights may from time to time be listed or quoted, or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights Certificates, whenever issued,
shall be dated as of the Record Date and on their face shall entitle the holders thereof to purchase such number of Fractional Shares of Preferred Stock as shall be set forth therein at the price set forth therein (such exercise price per Fractional
Share (or, as set forth in this Agreement, for other securities), the “Purchase Price”), but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as
provided herein. 
  
 (b) Any Rights Certificate issued pursuant to
Section 3(a) or Section 22 hereof that represents Rights beneficially owned by a Person described in the first sentence of Section 7(e), and any Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon 
  

 10 

 transfer, exchange, replacement or adjustment of any such Rights, shall contain (to the extent feasible) the following
legend, modified as applicable to apply to such Person: 
  
 The
Rights represented by this Rights Certificate are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Rights Agreement). Accordingly, this
Rights Certificate and the Rights represented hereby [will] [have] become null and void in the circumstances and with the effect specified in Section 7(e) of such Agreement. 
  
 The provisions of Section 7(e) of this Agreement shall be operative whether or not the foregoing legend is contained on any such Rights
Certificate. The Company shall give notice to the Rights Agent promptly after it becomes aware of the existence of any Acquiring Person or any Associate or Affiliate thereof. 
  
 Section 5. Countersignature and Registration. 
  
 (a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, its President or any
Vice President, either manually or by facsimile signature, and shall have affixed thereto the Company’s seal or a facsimile thereof, which shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Rights Certificates shall be countersigned by the Rights Agent, either manually or by facsimile signature, and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall have
signed any of the Rights Certificates shall cease to be such officer of the Company before countersignature by the Rights Agent and issuance and delivery by the Company, such Rights Certificates, nevertheless, may be countersigned by the Rights
Agent and issued and delivered by the Company with the same force and effect as though the person who signed such Rights Certificates had not ceased to be such officer of the Company; and any Rights Certificate may be signed on behalf of the Company
by any person who, at the actual date of the execution of such Rights Certificate, shall be a proper officer of the Company to sign such Rights Certificate, although at the date of the execution of this Rights Agreement any such person was not such
an officer. 
  
 (b) Following the Distribution Date, the Rights
Agent will keep or cause to be kept, at its principal office or offices designated as the appropriate place for surrender of Rights Certificates upon exercise or transfer, books for registration and transfer of the Rights Certificates issued
hereunder. Such books shall show the names and addresses of the respective holders of the Rights Certificates, the number of Rights evidenced on its face by each of the Rights Certificates and the certificate number and the date of each of the
Rights Certificates. 
  
 Section 6. Transfer, Split-Up,
Combination and Exchange of Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. 
  
 (a) Subject to the provisions of Section 4(b), Section 7(e), Section 13(d), Section 14 and Section 24 hereof, at any time after the close of business on
the Distribution Date, and at or prior to the close of business on the Expiration Date, any Rights Certificate or Rights Certificates may be transferred, split up, combined or exchanged for another Rights Certificate or 
  

 11 

 Rights Certificates, entitling the registered holder to purchase a like number of Fractional Shares of Preferred Stock
(or, following a Triggering Event, Common Stock, other securities, cash or other assets, as the case may be) as the Rights Certificate or Rights Certificates surrendered then entitled such holder (or former holder in the case of a transfer) to
purchase. Any registered holder desiring to transfer, split up, combine or exchange any Rights Certificate or Rights Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Rights
Certificates to be transferred, split up, combined or exchanged at the principal office or offices of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with
respect to the transfer of any such surrendered Rights Certificate until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Rights Certificate and shall have provided
such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) thereof or of the Affiliates or Associates thereof as the Company shall reasonably request. Thereupon the Rights Agent shall, subject to Section 4(b),
Section 7(e), Section 13(d), Section 14 and Section 24 hereof, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment by the holder of
a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split-up, combination or exchange of Rights Certificates. 
  
 (b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft,
destruction or mutilation of a Rights Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and reimbursement to the Company and the Rights Agent of all reasonable expenses incidental
thereto, and upon surrender to the Rights Agent and cancellation of the Rights Certificate if mutilated, the Company will, subject to Section 4(b), Section 7(e), Section 13(d), Section 14 and Section 24, execute and deliver a new Rights Certificate
of like tenor to the Rights Agent for countersignature and delivery to the registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated. 
  
 Section 7. Exercise of Rights; Purchase Price. 
  
 (a) Subject to Section 7(e) hereof, the registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein including, without limitation, the restrictions on exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a) hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly completed and executed, to the Rights Agent at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price with respect to the total number of Fractional Shares of Preferred Stock (or other securities, cash or other assets, as the case may be) as to which such surrendered Rights are then
exercisable, at or prior to the Expiration Date. 
  
 (b) The
Purchase Price for each Fractional Share of Preferred Stock pursuant to the exercise of a Right shall initially be $20.83 1/3, and shall be subject to adjustment from time to time as provided in Sections 11 and 13(a) hereof and shall be payable in accordance with paragraph (c) below. 
  

 12 

 (c) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to
purchase and the certificate on the reverse side thereof duly executed, accompanied by payment, with respect to each Right so exercised, of the Purchase Price per Fractional Share of Preferred Stock (or other shares, securities, cash or other
assets, as the case may be) to be purchased as set forth below and an amount equal to any applicable transfer tax, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly (i)(A) requisition from any transfer agent of the shares
of Preferred Stock (or make available, if the Rights Agent is the transfer agent for such shares) certificates for the total number of Fractional Shares of Preferred Stock to be purchased, and the Company hereby irrevocably authorizes its transfer
agent to comply with all such requests, or (B) if the Company, in its sole discretion, shall have elected to deposit the shares of Preferred Stock issuable upon exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing interests in such number of Fractional Shares of Preferred Stock as are to be purchased (in which case certificates for the shares of Preferred Stock represented by such receipts shall be deposited
by the transfer agent with the depositary agent) and the Company will direct the depositary agent to comply with such request, (ii) requisition from the Company the amount of cash, if any, to be paid in lieu of fractional shares in accordance with
Section 14 hereof, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by
such holder and (iv) after receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Rights Certificate. The payment of the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii) hereof)
may be made in cash or by certified check, cashier’s or official bank check or bank draft payable to the order of the Company or the Rights Agent. In the event that the Company is obligated to issue other securities (including Common Stock) of
the Company, pay cash and/or distribute other property pursuant to Section 11(a) or Section 13(a) hereof, the Company will make all arrangements necessary so that such other securities, cash and/or other property are available for distribution by
the Rights Agent, if and when appropriate. The Company reserves the right to require prior to the occurrence of a Triggering Event that, upon exercise of Rights, a number of Rights be exercised so that only whole shares of Preferred Stock would be
issued. 
  
 (d) In case the registered holder of any Rights
Certificate shall exercise fewer than all the Rights evidenced thereby, a new Rights Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the
registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, subject to the provisions of Section 14 hereof. 
  
 (e) Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of a Triggering Event,
any Rights beneficially owned by or transferred to (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person other than any such Person that became such pursuant to a Permitted Offer and the Board of Directors in good faith
determines was not involved in and did not cause or facilitate, directly or indirectly, such Triggering Event, (ii) a direct or indirect transferee of such Rights from such Acquiring Person (or any such Associate or Affiliate) who becomes a
transferee after such Triggering Event or (iii) a direct or indirect transferee of such Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with such Triggering Event and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from 
  

 13 

 such Acquiring Person (or such Affiliate or Associate) to holders of equity interests in such Acquiring Person (or such
Affiliate or Associate) or to any Person with whom such Acquiring Person (or such Affiliate or Associate) has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer that the Board of Directors of
the Company determines is part of a plan, arrangement or understanding that has as a primary purpose or effect the avoidance of this Section 7(e), shall become null and void without any further action, no holder of such Rights shall have any rights
whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise, and such Rights shall not be transferable. The Company shall use all reasonable efforts to ensure that the provisions of this Section 7(e) and
Section 4(b) hereof are complied with, but shall have no liability to any holder of Rights Certificates or other Person as a result of its failure to make any determinations with respect to an Acquiring Person or its Affiliates, Associates or
transferees hereunder. 
  
 (f) Notwithstanding anything in this
Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered
holder shall have (i) completed and signed the certificate contained in the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise and (ii) provided such additional evidence of the identity
of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request. 
  
 Section 8. Cancellation and Destruction of Rights Certificates. All Rights Certificates surrendered for the purpose of exercise, transfer,
split-up, combination or exchange shall, if surrendered to the Company or any of its agents, be delivered to the Rights Agent for cancellation or in canceled form, or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire,
any other Rights Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all canceled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such
canceled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company. 
  
 Section 9. Reservation and Availability of Capital Stock. 
  

(a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares, or out of its
authorized and issued shares held in its treasury, the number of shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) that, as provided in this Agreement, including Section 11(a)(iii)
hereof, will be sufficient to permit the exercise in full of all outstanding Rights. 
  
 (b) So long as any shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) issuable and deliverable upon the exercise of the Rights are listed on any
national securities exchange or quoted on any trading system, the Company shall use its best efforts to cause, from and after such time as the Rights 
  

 14 

 become exercisable, all shares reserved for such issuance to be listed on such exchange, or quoted on such system, upon
official notice of issuance upon such exercise. Following the occurrence of a Triggering Event, the Company will use its best efforts to list (or continue the listing of) the Rights and the securities issuable and deliverable upon the exercise of
the Rights on one or more national securities exchanges or to cause the Rights and the securities purchasable upon exercise of the Rights to be reported by NASDAQ or such other transaction reporting system then in use. 
  
 (c) The Company shall use its best efforts to (i) prepare and file, as soon
as practicable following the first occurrence of a Flip-In Event or, if applicable, as soon as practicable following the earliest date after the first occurrence of a Flip-In Event on which the consideration to be delivered by the Company upon
exercise of the Rights has been determined pursuant to this Agreement (including in accordance with Section 11(a)(iii) hereof), a registration statement on an appropriate form under the Securities Act with respect to the securities purchasable upon
exercise of the Rights, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of
the Securities Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities and (B) the Expiration Date. The Company will also take such action as may be appropriate under, or to ensure compliance with,
the securities or “blue sky” laws of the various states in connection with the exercisability of the Rights. The Company may temporarily suspend, for a period of time not to exceed 90 days after the date set forth in clause (i) of the
first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. In addition, if the Company shall determine that the Securities Act requires an
effective registration statement under the Securities Act following the Distribution Date, the Company may temporarily suspend the exercisability of the Rights until such time as such a registration statement has been declared effective. Upon any
such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction if the requisite qualification in such jurisdiction shall not have been obtained, the exercise thereof shall not be permitted under applicable law
or any required registration statement shall not have been declared effective. 
  
 (d) The Company covenants and agrees that it will take all such action as may be necessary to ensure that all Fractional Shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock
and/or other securities) delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable.

  
 (e) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges that may be payable in respect of the issuance or delivery of the Rights Certificates and of any certificates for a number of Fractional Shares of Preferred Stock (or
Common Stock and/or other securities, as the case may be) upon the exercise of Rights. The Company shall not, however, be required to pay any transfer tax that may be payable in respect of any transfer or delivery of Rights Certificates to a

  

 15 

 Person other than, or the issuance or delivery of a number of Fractional Shares of Preferred Stock (or Common Stock
and/or other securities, as the case may be) in respect of a name other than that of, the registered holder of the Rights Certificates evidencing Rights surrendered for exercise or to issue or deliver any certificates for a number of Fractional
Shares of Preferred Stock (or Common Stock and/or other securities, as the case may be) in a name other than that of the registered holder upon the exercise of any Rights until such tax shall have been paid (any such tax being payable by the holder
of such Rights Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax is due. 
  
 Section 10. Preferred Stock Record Date. Each Person in whose name any certificate for a number of Fractional Shares of Preferred Stock (or Common
Stock and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of such shares (fractional or otherwise) of Preferred Stock (or Common Stock and/or other
securities, as the case may be) represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and all applicable transfer taxes)
was made; provided, however, that if the date of such surrender and payment is a date upon which the Preferred Stock (or Common Stock and/or other securities, as the case may be) transfer books of the Company are closed, such Person shall be
deemed to have become the record holder of such shares (fractional or otherwise) on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred Stock (or Common Stock and/or other securities, as the case may be)
transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate, as such, shall not be entitled to any rights of a stockholder of the Company with respect to shares for which the
Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company,
except as provided herein. 
  
 Section 11. Adjustment of
Purchase Price, Number and Kind of Shares or Number of Rights. The Purchase Price, the number and kind of shares or other securities subject to purchase upon exercise of each Right and the number of Rights outstanding are subject to adjustment
from time to time as provided in this Section 11. 
  
 (a) (i) In the event the Company shall at any time after the Rights Dividend Declaration Date (A) declare a dividend on the outstanding shares of Preferred Stock payable in shares of Preferred Stock, (B) subdivide the outstanding shares of
Preferred Stock, (C) combine the outstanding shares of Preferred Stock into a smaller number of shares or (D) otherwise reclassify the outstanding shares of Preferred Stock (including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective
date of such subdivision, combination or reclassification, and the number and kind of shares of Preferred Stock or capital stock or other securities, as the 
  

 16 

 case may be, issuable on such date, shall be proportionately adjusted so that the holder of any Right
exercised after such time shall be entitled to receive, upon payment of the Purchase Price then in effect, the aggregate number and kind of shares of Preferred Stock or capital stock or other securities, as the case may be, which, if such Right had
been exercised immediately prior to such date and at a time when the Preferred Stock transfer books of the Company were open, he would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or
reclassification. If an event occurs that would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any
adjustment required pursuant to Section 11(a)(ii) hereof. 
  
 (ii) Subject to Sections 23 and 24 of this Agreement, in the event any Person shall, at any time after the Rights Dividend Declaration Date, become an Acquiring Person, unless the event causing such Person to become
an Acquiring Person is (1) a Flip-Over Event or (2) an acquisition of shares of Common Stock pursuant to a Permitted Offer (provided that this clause (2) shall cease to apply if such Acquiring Person thereafter becomes the Beneficial Owner of
any additional shares of Common Stock other than pursuant to such Permitted Offer or a transaction set forth in Section 13(a) or 13(d) hereof), then (x) the Purchase Price shall be adjusted to be the Purchase Price immediately prior to the first
occurrence of a Flip-In Event multiplied by the number of Fractional Shares of Preferred Stock for which a Right was exercisable immediately prior to such first occurrence and (y) each holder of a Right (except as provided below in Section
11(a)(iii) and in Section 7(e) hereof) shall thereafter have the right to receive, upon exercise thereof at a price equal to the Purchase Price in accordance with the terms of this Agreement, in lieu of the shares of Preferred Stock otherwise
purchasable thereunder, such number of shares of Common Stock of the Company as shall equal the result obtained by dividing the Purchase Price by 50% of the Current Market Price per share of Common Stock on the date of such first occurrence (such
number of shares, the “Adjustment Shares”); provided that the Purchase Price and the number of Adjustment Shares shall be further adjusted as provided in this Agreement to reflect any events occurring after the date of such first
occurrence. 
  
 (iii) In the event that the
number of shares of Common Stock that are authorized by the Company’s certificate of incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is not sufficient to permit the exercise in full
of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a), the Company shall, to the extent permitted by applicable law and regulation, (A) determine the excess of (1) the value of the Adjustment Shares issuable upon the
exercise of a Right (computed using the Current Market Price used to determine the number of Adjustment Shares) (the “Current Value”) over (2) the Purchase Price (such excess is herein referred to as the “Spread”), and (B) with
respect to each Right, make adequate provision to substitute for the Adjustment Shares, upon the exercise of the Rights and payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common Stock or other equity
securities of the Company (including, without limitation, shares, or units of shares, of preferred stock (including, without limitation, the Preferred Stock) that the Board of Directors of the Company has determined to have the same value as shares
of Common Stock (such shares of preferred stock are herein referred to as “Common Stock Equivalents”)), (4) debt securities of the Company, (5) other assets or (6) any combination of the foregoing, having an aggregate value equal to the
Current Value, where such aggregate value has been determined by the 
  

 17 

 Board of Directors of the Company based upon the advice of a nationally recognized investment banking
firm selected by the Board of Directors of the Company; provided, however, if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within 30 days following the later of (x) the first occurrence of a
Flip-In Event and (y) the date on which the Company’s right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the “Flip-In Trigger Date”), then the Company shall be obligated to
deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, shares of Common Stock (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the
Spread. If the Board of Directors of the Company shall determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, the 30-day period set forth
above may be extended to the extent necessary, but not more than 90 days after the Flip-In Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares (such period, as it may be extended, the
“Substitution Period”). To the extent that the Company or the Board of Directors determines that some action need be taken pursuant to the first and/or second sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to
Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares
and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability
of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of the Common Stock shall be the Current Market Price per share
of the Common Stock on the Flip-In Trigger Date and the value of any Common Stock Equivalent shall be deemed to have the same value as the Common Stock on such date. 
  
 (b) In case the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Preferred
Stock entitling them to subscribe for or purchase (for a period expiring within 45 calendar days after such record date) Preferred Stock (or shares having substantially the same rights, privileges and preferences as the shares of Preferred Stock
(“Equivalent Preferred Stock”)) or securities convertible into Preferred Stock or Equivalent Preferred Stock at a price per share of Preferred Stock or per share of Equivalent Preferred Stock (or having a conversion price per share, if a
security convertible into Preferred Stock or Equivalent Preferred Stock) less than the Current Market Price per share of Preferred Stock on such record date, the Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of shares of Preferred Stock outstanding on such record date, plus the number of shares of Preferred Stock that
the aggregate offering price of the total number of shares of Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such
Current Market Price, and the denominator of which shall be the number of shares of Preferred Stock outstanding on such record date, plus the number of additional shares of Preferred Stock and/or Equivalent Preferred Stock to be offered for
subscription or purchase 
  

 18 

 (or into which the convertible securities so to be offered are initially convertible). In case such subscription price
may be paid by delivery of consideration, part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors of the Company, whose determination shall be described in
a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Shares of Preferred Stock owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such
computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price that would then be in effect
if such record date had not been fixed. 
  
 (c) In case the
Company shall fix a record date for a distribution to all holders of Preferred Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving corporation) of evidences of
indebtedness, cash (other than a regular quarterly cash dividend out of the earnings or retained earnings of the Company), assets (other than a dividend payable in Preferred Stock, but including any dividend payable in stock other than Preferred
Stock) or subscription rights or warrants (excluding those referred to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the Current Market Price per share of Preferred Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent) of the portion of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants
applicable to a share of Preferred Stock and the denominator of which shall be such Current Market Price per share of Preferred Stock. Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such
distribution is not so made, the Purchase Price shall be adjusted to be the Purchase Price that would have been in effect if such record date had not been fixed. 
  
 (d) (i) For the purpose of any computation hereunder, other than computations made pursuant to Section 11(a)(iii) hereof,
the “Current Market Price” per share of Common Stock of a Person on any date shall be deemed to be the average of the daily Closing Prices per share of such Common Stock for the 30 consecutive Trading Days immediately prior to such date,
and for purposes of computations made pursuant to Section 11(a)(iii) hereof, the “Current Market Price” per share of Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of such Common Stock for
the 10 consecutive Trading Days immediately following such date; provided, however, that in the event that the Current Market Price per share of Common Stock is determined during a period following the announcement of (A) a dividend or
distribution on such Common Stock other than a regular quarterly cash dividend or the dividend of the Rights or (B) any subdivision, combination or reclassification of such Common Stock, and the ex-dividend date for such dividend or distribution, or
the record date for such subdivision, combination or reclassification, shall not have occurred prior to the commencement of the requisite 30 Trading Day or 10 Trading Day period, as set forth above, then, and in each such case, the Current Market
Price shall be properly adjusted to take into account ex-dividend trading. If the Common Stock is not publicly held or not so listed or traded, “Current Market Price” per share shall mean the fair value per share as determined in good
faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

 (ii) For the purpose of any computation hereunder, the “Current Market Price” per share (or
Fractional Share) of Preferred Stock shall be determined in the same manner as set forth above for the Common Stock in clause (i) of this Section 11(d) (other than the last sentence thereof). If the Current Market Price per share (or Fractional
Share) of Preferred Stock cannot be determined in the manner provided above or if the Preferred Stock is not publicly held or listed or traded in a manner described in clause (i) of this Section 11(d), the “Current Market Price” per share
of Preferred Stock shall be conclusively deemed to be an amount equal to 100 (as such number may be appropriately adjusted for such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock occurring after the
date of this Agreement) multiplied by the Current Market Price per share of the Common Stock. If neither the Common Stock nor the Preferred Stock is publicly held or so listed or traded, Current Market Price per share of the Preferred Stock shall
mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. For all purposes of this
Agreement, the Current Market Price of a Fractional Share of Preferred Stock shall be equal to the Current Market Price of one share of Preferred Stock divided by 100. 
  
 (e) Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the Purchase Price; provided, however, that any adjustments that by reason of this Section 11(e) are not required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest ten-thousandth of a share of Common Stock or other share or to the nearest ten-thousandth of a Fractional Share of Preferred Stock, as
the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction which mandates such adjustment or (ii)
the Expiration Date. 
  
 (f) If as a result of an adjustment made
pursuant to Section 11(a) or Section 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive in respect of such Right any shares of capital stock other than Preferred Stock, thereafter the number of such other
shares so receivable upon exercise of any Right and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock
contained in Sections 11(a), (b), (c), (e), (f), (g), (h), (i), (j), (k) and (m) hereof, and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like terms to any such other shares. 
  
 (g) All Rights originally issued by the Company subsequent to any adjustment
made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of Fractional Shares of Preferred Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further
adjustment as provided herein. 
  

 20 

 (h) Unless the Company shall have exercised its election as provided in Section 11(i) hereof, upon each
adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and (c) hereof, each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted
Purchase Price, that number of Fractional Shares of Preferred Stock (calculated to the nearest one ten-thousandth of a Fractional Share) obtained by (i) multiplying (x) the number of Fractional Shares of Preferred Stock covered by a Right
immediately prior to this adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price, and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the
Purchase Price. 
  
 (i) The Company may elect, on or after the
date of any adjustment of the Purchase Price, to adjust the number of Rights in lieu of any adjustment in the number of Fractional Shares of Preferred Stock purchasable upon the exercise of a Right. Each of the Rights outstanding after the
adjustment in the number of Rights shall be exercisable for the number of Fractional Shares of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number
of Rights shall become that number of Rights (calculated to the nearest ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after
adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This
record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least 10 days later than the date of the public announcement. If Rights Certificates have been
issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and
replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after
such adjustment. Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of
the holders of record of Rights Certificates on the record date specified in the public announcement. 
  
 (j) Irrespective of any adjustment or change in the Purchase Price or the number of Fractional Shares of Preferred Stock issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Purchase Price per Fractional Share and the number of Fractional Shares that were expressed in the initial Rights Certificates issued hereunder.

  
 (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, or the stated capital of the number of Fractional Shares of Preferred Stock or of the number of shares of Common Stock or other securities issuable upon exercise of a Right, the Company
shall take any corporate action that may, in the 
  

 21 

 opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable
such number of Fractional Shares of Preferred Stock or such number of shares of Common Stock or other securities at such adjusted Purchase Price. 
  
 (l) In any case in which this Section 11 shall require that an adjustment in the Purchase 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 the issuance to the holder of any Right exercised after such record date the number of Fractional Shares of Preferred Stock and other capital stock or securities of the
Company, if any, issuable upon such exercise over and above the number of Fractional Shares of Preferred Stock and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect
prior to such adjustment; provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional shares (fractional or otherwise) or
securities upon the occurrence of the event requiring such adjustment. 
  
 (m) Anything in this Section 11 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that
in their good faith judgment the Board of Directors of the Company shall determine to be advisable in order that any (i) consolidation or subdivision of the Preferred Stock, (ii) issuance wholly for cash of any shares of Preferred Stock at less than
the current market price, (iii) issuance wholly for cash of shares of Preferred Stock or securities that by their terms are convertible into or exchangeable for shares of Preferred Stock, (iv) stock dividends or (v) issuance of rights, options or
warrants referred to in this Section 11 hereafter made by the Company to holders of its Preferred Stock shall not be taxable to such stockholders. 
  
 (n) The Company covenants and agrees that it shall not, at any time that there is an Acquiring Person, (i) consolidate with any other Person, (ii) merge
with or into any other Person or (iii) sell, lease or transfer (or permit one or more Subsidiaries to sell, lease or transfer), in one transaction or a series of related transactions, assets, earning power or cash flow aggregating more than 50% of
the assets, earning power or cash flow of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons, if (x) at the time of or immediately after such consolidation, merger, sale, lease or transfer there are any rights,
warrants or other instruments or securities of the Company or any other Person outstanding or agreements, arrangements or understandings in effect that would substantially diminish or otherwise eliminate the benefits intended to be afforded by the
Rights, (y) prior to, simultaneously with or immediately after such consolidation, merger, sale, lease or transfer, the stockholders or other equity owners of the Person who constitutes, or would constitute, the “Principal Party” for
purposes of Section 13(a) hereof shall have received a distribution of Rights previously owned by such Person or any of its Affiliates or Associates, or (z) the identity, form or nature of organization of the Principal Party (including, without
limitation, the selection of the Person that will be the Principal Party as a result of the Company’s entering into one or more consolidations, mergers, sales, leases or transfers with more than one party) would preclude or limit the exercise
of Rights or otherwise diminish substantially or eliminate the benefits intended to be afforded by the Rights. 
  

 22 

 (o) The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted
by Section 23, Section 24 or Section 27 hereof, take (or permit any Subsidiary to take) any action if the purpose of such action is to, or if at the time such action is taken it is reasonably foreseeable that such action will, diminish substantially
or eliminate the benefits intended to be afforded by the Rights. 
  
 (p) Notwithstanding Section 3(c) hereof or any other provision of this Agreement to the contrary, in the event that the Company shall at any time after the Rights Dividend Declaration Date and prior to the Distribution Date (i) declare a
dividend on the outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding shares of Common Stock, (iii) combine the outstanding shares of Common Stock into a smaller number of shares or (iv) otherwise
reclassify the outstanding shares of Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), the number of Rights associated with each share of
Common Stock then outstanding, or issued or delivered thereafter with Rights, shall be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result
obtained by multiplying the number of Rights associated with each share of Common Stock immediately prior to such event by a fraction (the “Adjustment Fraction”), the numerator of which shall be the total number of shares of Common Stock
outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of Common Stock outstanding immediately following the occurrence of such event. In lieu of such adjustment in the number of
Rights associated with one share of Common Stock, the Company may elect to adjust the number of Fractional Shares of Preferred Stock purchasable upon the exercise of one Right and the Purchase Price. If the Company makes such election, the number of
Rights associated with one share of Common Stock shall remain unchanged, and the number of Fractional Shares of Preferred Stock purchasable upon exercise of one Right and the Purchase Price shall be proportionately adjusted so that (i) the number of
Fractional Shares of Preferred Stock purchasable upon exercise of a Right following such adjustment shall equal the product of the number of Fractional Shares of Preferred Stock purchasable upon exercise of a Right immediately prior to such
adjustment multiplied by the Adjustment Fraction and (ii) the Purchase Price following such adjustment shall remain unchanged, with the effect that the amount payable to exercise each Right will be changed to be equal the product of the Purchase
Price immediately prior to such adjustment multiplied by the Adjustment Fraction. 
  
 Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as provided in Section 11 or Section 13 hereof, the Company shall (a) promptly prepare a certificate
setting forth such adjustment and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Rights Agent, and with each transfer agent for the Preferred Stock and the Common Stock, a copy of such certificate and (c)
mail a brief summary thereof to each registered holder of a Rights Certificate (or, if prior to the Distribution Date, to each registered holder of a certificate representing shares of Common Stock) in accordance with Section 26 hereof. The Rights
Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained. 
  

 23 

 Section 13. Consolidation, Merger or Sale or Transfer of Assets, Cash Flow or Earning Power.

  
 (a) In the event that, from and after the time an Acquiring
Person has become such, directly or indirectly, (x) the Company shall consolidate with, or merge with and into, any other Person, and the Company shall not be the continuing or surviving corporation of such consolidation or merger, (y) any Person
shall consolidate with, or merge with or into, the Company, and the Company shall be the continuing or surviving corporation of such consolidation or merger, and, in connection with such consolidation or merger, all or part of the outstanding shares
of Common Stock shall be changed into or exchanged for stock or other securities of the Company or any other Person or cash or any other property, or (z) the Company shall sell, lease or otherwise transfer (or one or more of its Subsidiaries shall
sell, lease or otherwise transfer), in one transaction or a series of related transactions, assets, cash flow or earning power aggregating more than 50% of the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole)
to any Person or Persons (other than the Company or any wholly owned Subsidiary of the Company or any combination thereof in one or more transactions each of which complies (and all of which together comply) with Section 11(o) hereof), then, and in
each such case (except as may be contemplated by Section 13(d) hereof), proper provision shall be made so that: (i) the Purchase Price shall be adjusted to be the Purchase Price immediately prior to the first occurrence of a Triggering Event
multiplied by the number of Fractional Shares of Preferred Stock for which a Right was exercisable immediately prior to such first occurrence; (ii) on and after the Distribution Date, each holder of a Right, except as provided in Section 7(e)
hereof, shall thereafter have the right to receive, upon the exercise thereof at the Purchase Price in accordance with the terms of this Agreement, in lieu of shares of Preferred Stock or Common Stock of the Company, such number of validly
authorized and issued, fully paid, nonassessable and freely tradeable shares of Common Stock of the Principal Party (as such term is hereinafter defined), not subject to any liens, encumbrances, rights of first refusal or other adverse claims, as
shall be equal to the result obtained by dividing the Purchase Price by 50% of the Current Market Price per share of the Common Stock of such Principal Party on the date of consummation of such Flip-Over Event; provided that the Purchase
Price and the number of shares of Common Stock of such Principal Party issuable upon exercise of each Right shall be further adjusted as provided in this Agreement to reflect any events occurring after the date of such first occurrence of a
Triggering Event or after the date of such Flip-Over Event, as applicable; (iii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Flip-Over Event, all the obligations and duties of the Company pursuant to this
Agreement; (iv) the term “Company” shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party following the first occurrence
of a Flip-Over Event; (v) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of shares of its Common Stock) in connection with the consummation of any such transaction as may be
necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to its shares of Common Stock thereafter deliverable upon the exercise of the Rights; and (vi) the provisions of Section
11(a)(ii) hereof shall be of no effect following the occurrence of any Flip-Over Event. 
  
 (b) “Principal Party” shall mean 
  
 (i) in the case of any transaction described in clause (x) or (y) of the first sentence of Section 13(a), (A) the Person that is the issuer of any securities into which shares of Common Stock of the Company are
converted in such merger or consolidation, 
  

 24 

 or, if there is more than one such issuer, the issuer the Common Stock of which has the greatest
aggregate market value, or (B) if no securities are so issued, (x) the Person that survives such consolidation or is the other party to the merger and survives such merger, or, if there is more than one such Person, the Person the Common Stock of
which has the greatest aggregate market value or (y) if the Person that is the other party to the merger does not survive the merger, the Person that does survive the merger (including the Company if it survives); and 
  
 (ii) in the case of any transaction described in clause (z)
of the first sentence of Section 13(a), the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions, or, if each Person that is a party to such transaction or
transactions receives the same portion of the assets or earning power so transferred, or if the Person receiving the greatest portion of the assets or earning power cannot be determined, the Person the Common Stock of which has the greatest
aggregate market value; 
  
 provided, however, that in any such case, if
the Common Stock of such Person is not at such time and has not been continuously over the preceding twelve-month period registered under Section 12 of the Exchange Act, and if (1) such Person is a direct or indirect Subsidiary of another Person the
Common Stock of which is and has been so registered, “Principal Party” shall refer to such other Person; (2) such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Stocks of all of which are and have been
so registered, “Principal Party” shall refer to whichever of such Persons is the issuer of the Common Stock having the greatest aggregate market value; and (3) such Person is owned, directly or indirectly, by a joint venture formed by two
or more Persons that are not owned, directly or indirectly, by the same Person, the rules set forth in (1) and (2) above shall apply to each of the chains of ownership having an interest in such joint venture as if such party were a
“Subsidiary” of both or all of such joint venturers and the Principal Parties in each such chain shall bear the obligations set forth in this Section 13 in the same ratio as their direct or indirect interests in such Person bear to the
total of such interests. 
  
 (c) The Company shall not consummate
any Flip-Over Event unless each Principal Party (or Person that may become a Principal Party as a result of such Flip-Over Event) shall have a sufficient number of authorized shares of its Common Stock that have not been issued or reserved for
issuance to permit the exercise in full of the Rights in accordance with this Section 13 and unless prior thereto the Company and each such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement providing for
the terms set forth in paragraphs (a) and (b) of this Section 13 and further providing that, as soon as practicable after the date of such Flip-Over Event, the Principal Party at its own expense will 
  
 (i) prepare and file a registration statement under the
Securities Act with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, and will use its best efforts to cause such registration statement to (A) become effective as soon as practicable after such
filing and (B) remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Expiration Date; 
  

 25 

 (ii) use its best efforts to qualify or register the Rights and the securities
purchasable upon exercise of the Rights under the “blue sky” laws of such jurisdictions as may be necessary or appropriate; 
  
 (iii) use its best efforts, if the Common Stock of the Principal Party is or shall become listed on a national securities exchange, to
list (or continue the listing of) the Rights and the securities purchasable upon exercise of the Rights on such securities exchange and, if the Common Stock of the Principal Party shall not be listed on a national securities exchange, to cause the
Rights and the securities purchasable upon exercise of the Rights to be reported by NASDAQ or such other transaction reporting system then in use; and 
  
 (iv) deliver to holders of the Rights historical financial statements for the Principal Party and each of its Affiliates that comply in
all respects with the requirements for registration on Form 10 under the Exchange Act. 
  
 The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other transfers. In the event that a Flip-Over Event shall occur at any time after the occurrence of a Flip-In Event, the Rights
that have not theretofore been exercised shall thereafter become exercisable in the manner described in Section 13(a). 
  
 (d) Notwithstanding anything in this Agreement to the contrary, Section 13 shall not be applicable to a transaction described in subparagraphs (x) and (y)
of Section 13(a) if (i) such transaction is consummated with a Person or Persons who acquired shares of Common Stock pursuant to a Permitted Offer (or a wholly owned Subsidiary of any such Person or Persons), (ii) the price per share of Common Stock
offered in such transaction is not less than the price per share of Common Stock paid to all holders of Common Stock whose shares were purchased pursuant to such Permitted Offer, and (iii) the form of consideration being offered to the remaining
holders of shares of Common Stock pursuant to such transaction is the same as the form of consideration paid pursuant to such Permitted Offer. Upon consummation of any such transaction contemplated by this Section 13(d), all Rights hereunder shall
expire. 
  
 Section 14. Fractional Rights and Fractional
Shares. 
  
 (a) The Company shall not be required to issue
fractions of Rights, except prior to the Distribution Date as provided in Section 11(p) hereof, or to distribute Rights Certificates or scrip evidencing fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered
holders of the Rights Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the Closing Price of one Right for the Trading Day immediately prior to the date on which
such fractional Rights would have been otherwise issuable. 
  
 (b)
The Company shall not be required to issue fractions of shares of Preferred Stock (other than, except as provided in Section 7(c) hereof, fractions that are integral multiples of a Fractional Share of Preferred Stock) upon exercise of the Rights or
to distribute certificates or scrip evidencing fractional shares of Preferred Stock (other than, except as provided in Section 7(c) hereof, fractions that are integral multiples of a Fractional Share of 
  

 26 

 Preferred Stock). Interests in fractions of shares of Preferred Stock in integral multiples of a Fractional Share of
Preferred Stock may, at the election of the Company in its sole discretion, be evidenced by depositary receipts, pursuant to an appropriate agreement between the Company and a depositary selected by it, provided that such agreement shall provide
that the holders of such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners of the shares of Preferred Stock represented by such depositary receipts. In lieu of fractional shares
of Preferred Stock that are not integral multiples of a Fractional Share of Preferred Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the
same fraction of one one-hundredth of the Closing Price of a share of Preferred Stock for the Trading Day immediately prior to the date of such exercise. 
  
 (c) Following the occurrence of a Triggering Event, the Company shall not be required to issue fractions of shares of Common Stock upon exercise of the
Rights or to distribute certificates or scrip evidencing fractional shares of Common Stock. In lieu of fractional shares of Common Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are exercised as
herein provided an amount in cash equal to the same fraction of the Closing Price of one share of Common Stock for the Trading Day immediately prior to the date of such exercise. 
  
 (d) The holder of a Right by the acceptance of the Right expressly waives his right to receive any fractional Rights or any
fractional shares upon exercise of a Right, except as permitted by this Section 14. 
  
 Section 15. Rights of Action. All rights of action in respect of this Agreement, other than rights of action vested in the Rights Agent pursuant to Section 18 hereof, are vested in the respective registered
holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common Stock) and, where applicable, the Company; and any registered holder of any Rights Certificate (or, prior to the Distribution Date, of the
Common Stock), without the consent of the Rights Agent or of the holder of any other Rights Certificate (or, prior to the Distribution Date, of the Common Stock), may, in his own behalf and for his own benefit, enforce, and may institute and
maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Rights Certificate in the manner provided in such Rights Certificate and in this Agreement.
Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and shall be entitled to specific
performance of the obligations hereunder and injunctive relief against actual or threatened violations of the obligations hereunder of any Person subject to this Agreement. After a Triggering Event, holders of Rights shall be entitled to recover the
reasonable costs and expenses, including attorneys’ fees, incurred by them in any action to enforce the provisions of this Agreement. 
  

 27 

 Section 16. Agreement of Rights Holders . Every holder of a Right by accepting the same consents
and agrees with the Company and the Rights Agent and with every other holder of a Right that: 
  
 (a) prior to the Distribution Date, the Rights will not be evidenced by Rights Certificates and will be transferable only in connection with the transfer of Common Stock; 
  
 (b) after the Distribution Date, the Rights Certificates will be transferable
only on the registry books of the Rights Agent if surrendered at the principal office or offices of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the form of assignment set
forth on the reverse side thereof and the certificate contained therein duly completed and fully executed; 
  
 (c) subject to Section 6(a) and Section 7(f) hereof, the Company and the Rights Agent may deem and treat the Person in whose name a Rights Certificate
(or, prior to the Distribution Date, the associated Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Rights Certificates or the
associated Common Stock certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary; and 
  
 (d) notwithstanding anything in this Agreement to the contrary, neither the
Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order,
decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority,
prohibiting or otherwise restraining performance of such obligation; provided, however, the Company must use its best efforts to have any such order, decree or ruling lifted or otherwise overturned as soon as possible. 
  
 Section 17. Rights Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose the holder of the number of Fractional Shares of Preferred Stock or any other securities of the Company that may at any time be
issuable upon the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed to confer upon the holder of any Rights Certificate, as such, any of the rights of a stockholder of the
Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof.

  

 28 

 Section 18. Concerning the Rights Agent. 
  
 (a) The Company agrees to pay to the Rights Agent reasonable compensation
for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and
performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability or expense, incurred without negligence, bad faith or willful misconduct on the part of the Rights
Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending against any claim of liability in the premises. 
  
 (b) The Rights Agent shall be protected and shall incur no liability for or
in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any Rights Certificate or certificate for the Preferred Stock or Common Stock or for other securities of the Company,
instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document believed by it, to be genuine and to be signed, executed and, where necessary,
verified or acknowledged, by the proper person or persons, or otherwise upon the advice of counsel as set forth in Section 20 hereof. 
  
 Section 19. Merger or Consolidation or Change of Name of Rights Agent. 
  
 (a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or with which it may be
consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding to the stock transfer or corporate trust powers of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided, that such corporation would be
eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Rights Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not
have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have
the full force provided in the Rights Certificates and in this Agreement. 
  
 (b) In case at any time the name of the Rights Agent shall be changed and at such time any of the Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or
in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. 
  

 29 

 Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties and obligations imposed
by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound: 
  
 (a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such
counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion. 
  
 (b) Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable
that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer, or the Secretary of the Company and delivered to the Rights Agent; and such
certificate shall be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate. 
  
 (c) The Rights Agent shall be liable hereunder to the Company and any other Person only for its own negligence, bad faith or
willful misconduct. 
  
 (d) The Rights Agent shall not be liable
for or by reason of any of the statements of fact or recitals contained in this Agreement or in the Rights Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and shall be
deemed to have been made by the Company only. 
  
 (e) The Rights
Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Rights Certificate
(except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Rights Certificate; nor shall it be responsible for any change in the exercisability
of the Rights (including the Rights becoming void pursuant to Section 7(e) hereof) or any adjustment in the terms of the Rights (including the manner, method or amount thereof) provided for in Section 3, 11, 13, 23 or 24 or the ascertaining of the
existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Rights Certificates after actual notice that such change or adjustment is required); nor shall it by any act hereunder be deemed to
make any representation or warranty as to the authorization or reservation of any Preferred Stock to be issued pursuant to this Agreement or any Rights Certificate or as to whether any Preferred Stock will, when issued, be validly authorized and
issued, fully paid and nonassessable. 
  

 30 

 (f) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed,
executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement.

  
 (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Secretary or the Treasurer of the Company, and to apply to
such officers for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith in accordance with instructions of any such officer or for any delay in acting while waiting for
those instructions. 
  
 (h) The Rights Agent and any stockholder,
director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which 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 Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity.

  
 (i) The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys
or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct; provided, reasonable care was exercised in the selection and continued employment thereof. 
  
 Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in writing mailed to the Company, and to each transfer agent of the Common Stock and the Preferred Stock, by registered or certified mail, and
to the holders of the Rights Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon 30 days’ notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and
to each transfer agent of the Common Stock or Preferred Stock, by registered or certified mail, and to the holders of the Rights Certificates, by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of 30 days after giving notice of such removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then the registered holder of any Rights Certificate may
apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United
States or of the State of Oklahoma (or of any other state of the United States so long as such corporation is authorized to do business as a banking institution in the State of Oklahoma), in good standing, having an office in the State of Oklahoma,
which is authorized under such laws to exercise corporate trust or 
  

 31 

 stock transfer powers and is subject to supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at least $50 million. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance,
act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock or Preferred Stock, and
mail a notice thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be. 
  
 Section 22. Issuance of New Rights Certificates. Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Rights Certificates made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of shares of Common Stock following the Distribution Date and prior to
the Expiration Date, the Company (a) shall, with respect to shares of Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement granted or awarded on or prior to the Distribution Date, or upon
the exercise, conversion or exchange of securities issued by the Company on or prior to the Distribution Date, and (b) may, in any other case, if deemed necessary or appropriate by the Board of Directors of the Company, issue Rights Certificates
representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Rights Certificate shall be issued if, and to the extent that, the Company shall be advised by counsel that such issuance
would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Rights Certificate would be issued, and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof. 
  
 Section 23. Redemption and Termination. 
  
 (a)
The Board of Directors of the Company may, at its option, at any time prior to the earlier of (i) the close of business on the tenth day following the first date of public announcement of the occurrence of a Flip-In Event (or, if such date shall
have occurred prior to the Record Date, the close of business on the tenth day following the Record Date) and (ii) the Expiration Date, cause the Company to redeem all but not less than all the then outstanding Rights at a redemption price of $.01
per Right, as such amount may be appropriately adjusted, if necessary, to reflect any stock split, stock dividend or similar transaction occurring after the Rights Dividend Declaration Date (such redemption price being hereinafter referred to as the
“Redemption Price”); provided, however, that the Rights may not be redeemed following any merger to which the Company is a party that (i) occurs when there is an Acquiring Person and (ii) was not approved (x) prior to the time such
Person became an Acquiring Person by the Board 
  

 32 

 of Directors of the Company and (y) prior to such merger by the stockholders of the Company at a stockholders’
meeting (and not by written consent). Notwithstanding anything contained in this Agreement to the contrary, the Rights shall not be exercisable after the first occurrence of a Flip-In Event until such time as the Company’s right of redemption
hereunder has expired. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on the Current Market Price of the Common Stock at the time of redemption) or any other form of consideration deemed appropriate
by the Board of Directors. 
  
 (b) Immediately upon the
effectiveness of the action of the Board of Directors of the Company ordering the redemption of the Rights (the effectiveness of which action may be conditioned on the occurrence of one or more events or on the existence of one or more facts or may
be effective at some future time), evidence of which shall be filed with the Rights Agent and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price for each Right so held. Promptly after the effectiveness of the action of the Board of Directors ordering the redemption of the Rights, the Company shall give notice of such redemption to the Rights Agent and
the registered holders of the then outstanding Rights by mailing such notice to all such holders at each holder’s last address as it appears upon the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books
of the Company for the Common Stock. Any notice that is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption shall state the method by which the payment of the
Redemption Price will be made. 
  
 Section 24. Exchange.

  
 (a) The Board of Directors of the Company may, at its option,
at any time and from time to time after the occurrence of a Flip-In Event, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 7(e) hereof)
for shares of Common Stock or Common Stock Equivalents or any combination thereof, at an exchange ratio of one share of Common Stock, or such number of Common Stock Equivalents or units representing fractions thereof as would be deemed to have the
same value as one share of Common Stock, per Right, appropriately adjusted, if necessary, to reflect any stock split, stock dividend or similar transaction occurring after the Rights Dividend Declaration Date (such exchange ratio being hereinafter
referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board of Directors may not effect such exchange at any time after (i) any Person (other than an Exempt Person), together with all Affiliates and Associates of such
Person, becomes the Beneficial Owner of 50% or more of the shares of Common Stock then outstanding or (ii) the occurrence of a Flip-Over Event. 
  
 (b) Immediately upon the effectiveness of the action of the Board of Directors of the Company ordering the exchange of any Rights pursuant to and in
accordance with subsection (a) of this Section 24 (the effectiveness of which action may be conditioned on the occurrence of one or more events or on the existence of one or more facts or may be effective at some future time) and without any further
action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to receive that number of shares of Common Stock and/or Common Stock Equivalents equal to the

  

 33 

 number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice
of any such exchange; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the registered holders of
such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of
exchange will state the method by which the exchange of the shares of Common Stock and/or Common Stock Equivalents for Rights will be effected and, in the event of any partial exchange, the number of Rights that will be exchanged. Any partial
exchange shall be effected as nearly pro rata as possible based on the number of Rights (other than Rights that have become void pursuant to the provisions of Section 7(e) hereof) held by each holder of Rights. 
  
 (c) In the event that the number of shares of Common Stock that are
authorized by the Company’s certificate of incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is not sufficient to permit an exchange of Rights as contemplated in accordance with this
Section 24, the Company may, at its option, take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exchange of the Rights. 
  
 (d) The Company shall not be required to issue fractions of shares of Common Stock or to distribute certificates or scrip
evidencing fractional shares of Common Stock upon exchange of the Rights. In lieu of such fractional shares of Common Stock, the Company shall pay to the registered holders of Rights with regard to which such fractional shares of Common Stock would
otherwise be issuable an amount in cash equal to the same fraction of the value of a whole share of Common Stock. For purposes of this Section 24, the value of a whole share of Common Stock shall be the Closing Price per share of Common Stock for
the Trading Day immediately prior to the date of exchange pursuant to this Section 24, and the value of any Common Stock Equivalent shall be deemed to have the same value as the Common Stock on such date. 
  
 Section 25. Notice of Certain Events. 
  
 (a) In case the Company shall propose, at any time after the Distribution
Date, (i) to pay any dividend payable in stock of any class to the holders of Preferred Stock or to make any other distribution to the holders of Preferred Stock (other than a regular quarterly cash dividend out of earnings or retained earnings of
the Company), or (ii) to offer to the holders of Preferred Stock rights or warrants to subscribe for or to purchase any additional shares of Preferred Stock or shares of stock of any class or any other securities, rights or options, or (iii) to
effect any reclassification of its Preferred Stock (other than a reclassification involving only the subdivision of outstanding shares of Preferred Stock), or (iv) to effect any consolidation or merger into or with any other Person (other than a
wholly owned Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), or to effect any sale, lease or other transfer of all or substantially all the Company’s assets, cash flow or earning power to any other Person or
Persons (other than a wholly owned Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to
each holder of record of a Rights 
  

 34 

 Certificate, to the extent feasible and in accordance with Section 26 hereof, a notice of such proposed action, which
shall specify the record date for the purposes of such stock dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, lease, transfer, liquidation, dissolution or winding up is to take
place and the date of participation therein by the holders of the shares of Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least 20 days prior to
the record date for determining holders of the shares of Preferred Stock for purposes of such action, and in the case of any such other action, at least 20 days prior to the date of the taking of such proposed action or the date of participation
therein by the holders of the shares of Preferred Stock, whichever shall be the earlier. The failure to give notice required by this Section 25 or any defect therein shall not affect the legality or validity of the action taken by the Company or the
vote upon any such action. 
  
 (b) In case any Flip-In Event or
Flip-Over Event shall occur, then (i) the Company shall as soon as practicable thereafter give to each registered holder of a Rights Certificate (or if occurring prior to the Distribution Date, the registered holders of Common Stock), in accordance
with Section 26 hereof, a notice of the occurrence of such event, which shall specify the event and the consequences of the event to holders of Rights under Section 11(a)(ii) or Section 13(a) hereof, and (ii) all references in the preceding
paragraph to Preferred Stock shall be deemed thereafter to refer to Common Stock and/or, if appropriate, other securities. 
  
 Section 26. Notices. Notices or demands authorized by this Agreement to be given or made by the Rights Agent or by the holder of any Rights
Certificate to or on the Company shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Rights Agent) as follows:

 4322 South 49th West Avenue 
 Tulsa, Oklahoma 74107

 Subject to the provisions of Section 21, any notice or demand authorized by this Agreement to

Company) as follows:

 40 Wall Street, 46th Floor

 Notices or demands authorized by this Agreement to be given or made by the Company or the Rights Agent to the holder of any Rights Certificate (or, if prior to the
Distribution Date, to the holder of certificates representing shares of Common Stock) shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed to such holder at the address of such holder as shown on the registry
books of the Company. 
  

 35 

 Section 27. Supplements and Amendments. Except as provided in the last sentence of this Section
27, at any time when the Rights are then redeemable, the Company may in its sole and absolute discretion and the Rights Agent shall, if the Company so directs, supplement or amend any provision of this Agreement in any respect without the approval
of any holders of Rights or holders of Common Stock. At any time when the Rights are not redeemable, except as provided in the last sentence of this Section 27, the Company may and the Rights Agent shall, if the Company so directs, supplement or
amend this Agreement without the approval of any holders of Rights in order (i) to cure any ambiguity, (ii) to correct or supplement any provision contained herein that may be defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder or (iv) to change or supplement the provisions hereunder in any manner that the Company may deem necessary or desirable; provided that no such amendment or supplement shall materially adversely affect
the interests of the holders of Rights (other than an Acquiring Person or an Affiliate or Associate of an Acquiring Person); and further provided that this Agreement may not be supplemented or amended pursuant to this sentence to lengthen (A) a time
period relating to when the Rights may be redeemed or (B) any other time period unless the lengthening of such other time period is for the purpose of protecting, enhancing or clarifying the rights of, and/or the benefits to, the holders of Rights
(other than any Acquiring Person and its Affiliates and Associates). Upon the delivery of a certificate from an appropriate officer of the Company which states that the proposed supplement or amendment is in compliance with the terms of this Section
27, the Rights Agent shall execute such supplement or amendment; provided, however, that the Rights Agent may, but shall not be obligated to, enter into any such supplement or amendment that affects the Rights Agent’s own rights, duties or
immunities under this Agreement. Notwithstanding anything contained in this Agreement to the contrary, no supplement or amendment shall be made that decreases the Redemption Price. 
  
 Section 28. Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or
the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder. 
  
 Section 29. Determinations and Actions by the Board of Directors, etc. For all purposes of this Agreement, any calculation of the number of
shares of Common Stock outstanding at any particular time, including for purposes of determining the particular percentage of such outstanding shares of Common Stock of which any Person is the Beneficial Owner, shall be made in accordance with the
last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act as in effect on the date of this Agreement. The Board of Directors of the Company (or, as set forth herein, certain specified members thereof) shall
have the exclusive power and authority to administer this Agreement and to exercise all rights and powers specifically granted to the Board of Directors of the Company or to the Company, or as may be necessary or advisable in the administration of
this Agreement, including, without limitation, the right and power to (i) interpret the provisions of this Agreement and (ii) make all determinations deemed necessary or advisable for the administration of this Agreement (including, without
limitation, a determination to redeem or not redeem the Rights or to amend this Agreement). All such actions, calculations, interpretations and determinations (including, for purposes of clause (y) below, all omissions with respect to the foregoing)
that are done or made by the Board of Directors of the Company in good faith, shall (x) be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights, as such, and all other parties, and (y) not subject the Board of
Directors to any liability to the holders of the Rights. 
  

 36 

 Section 30. Benefits of this Agreement. Nothing in this Agreement shall be construed to give to
any Person other than the Company, the Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of the Common Stock) any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, registered holders of the Common Stock).

  
 Section 31. Severability. If any term, provision,
covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full
force and effect and shall in no way be affected, impaired or invalidated; provided, however, that notwithstanding anything in this Agreement to the contrary, if any such term, provision, covenant or restriction is held by such court or authority to
be invalid, void or unenforceable and the Board of Directors of the Company determines in its good faith judgment that severing the invalid language from this Agreement would adversely affect the purpose or effect of this Agreement, then, unless
there has occurred a merger referred to in the proviso to the first sentence of Section 23(a), the right of redemption set forth in Section 23 hereof shall be reinstated and shall not expire until the close of business on the tenth day following the
date of such determination by the Board of Directors of the Company or, if earlier, immediately prior to any such merger. Without limiting the foregoing, if any provision requiring that a determination be made by less than the entire Board of
Directors of the Company is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, such determination shall then be made by the entire Board of Directors of the Company. 
  
 Section 32. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed in accordance with the laws of such State applicable to contracts made and to be
performed entirely within such State. 
  
 Section 33.
Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

  
 Section 34. Descriptive Headings. Descriptive headings
of the several Sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

 Exhibit A 
  
 FORM OF 
 AMENDED AND RESTATED

 CERTIFICATE OF DESIGNATIONS 
 of 
 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK 
 of 
 SYNTROLEUM CORPORATION 
  
 Pursuant to Section 151 of the General Corporation Law 
 of the State of Delaware 
  
 SYNTROLEUM CORPORATION, a corporation organized and existing under the General Corporation Law of the State of Delaware, in accordance with the provisions
of Section 103 thereof, DOES HEREBY CERTIFY: 
  
 That (i) on June
17, 1999 a Certificate of Designation of said Corporation was filed with the Secretary of State of the State of Delaware pursuant to Section 151 of the General Corporation Law of the State of Delaware with respect to a series of 250,000 shares of
Preferred Stock designated as “Series A Junior Participating Preferred Stock”, (ii) no shares of such series have been issued as of the date hereof and (iii) pursuant to the authority vested in the Board of Directors in accordance with the
provisions of the Certificate of Incorporation of the said Corporation, the said Board of Directors on October 24, 2004 adopted the following resolution amending and restating the terms of a series of 250,000 shares of Preferred Stock designated as
“Series A Junior Participating Preferred Stock:” 
  
 RESOLVED, that pursuant to the authority vested in the Board of Directors of this Corporation in accordance with the provisions of the Certificate of Incorporation, a series of Preferred Stock, par value $.01 per
share, of the Corporation be and hereby is created, and that the designation and number of shares thereof and the voting and other powers, preferences and relative, participating, optional or other rights of the shares of such series and the
qualifications, limitations and restrictions thereof are as follows: 
  
 Series A Junior Participating Preferred Stock 
  
 1. Designation and Amount. There shall be a series of Preferred Stock that shall be designated as “Series A Junior Participating Preferred Stock,” and the number of shares constituting such series shall be 250,000. Such
number of shares may be increased or decreased by resolution of the Board of Directors; provided, however, that no decrease shall reduce the number of shares of Series A Junior Participating Preferred Stock to less than the number of shares then
issued and outstanding plus the number of shares issuable upon exercise of outstanding rights, options or warrants or upon conversion of outstanding securities issued by the Corporation. 
  

 A-1 

 2. Dividends and Distributions. 
  
 (A) Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and
superior to the shares of Series A Junior Participating Preferred Stock with respect to dividends, the holders of shares of Series A Junior Participating Preferred Stock, in preference to the holders of shares of any class or series of stock of the
Corporation ranking junior to the Series A Junior Participating Preferred Stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on
the 15th day of March, June, September and December in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share
or fraction of a share of Series A Junior Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b) the Adjustment Number (as defined below) times the aggregate per share amount of
all cash dividends, and the Adjustment Number times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares
of Common Stock (by reclassification or otherwise), declared on the Common Stock, par value $.01 per share, of the Corporation (the “Common Stock”) since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Junior Participating Preferred Stock. The “Adjustment Number” shall initially be 100. In the event the Corporation shall at any
time after October 24, 2004 (the “Rights Declaration Date”) (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 
  
 (B) The Corporation shall declare a dividend or distribution on the Series A Junior Participating Preferred Stock as
provided in paragraph (A) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution shall have been declared
on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Series A Junior Participating Preferred Stock shall nevertheless be
payable on such subsequent Quarterly Dividend Payment Date. 
  
 (C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Junior Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series A Junior
Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Junior Participating Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend 
  

 A-2 

 Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly
Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Junior Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Junior Participating Preferred Stock
entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. 
  
 3. Voting Rights. The holders of shares of Series A Junior Participating Preferred Stock shall have the following
voting rights: 
  
 (A) Each share of Series A Junior
Participating Preferred Stock shall entitle the holder thereof to a number of votes equal to the Adjustment Number on all matters submitted to a vote of the stockholders of the Corporation. 
  
 (B) Except as otherwise provided herein, in the Certificate of Incorporation
or by law, the holders of shares of Series A Junior Participating Preferred Stock, the holders of shares of any other class or series entitled to vote with the Common Stock and the holders of shares of Common Stock shall vote together as one class
on all matters submitted to a vote of stockholders of the Corporation. 
  
 (C) (i) If at any time dividends on any Series A Junior Participating Preferred Stock shall be in arrears in an amount equal to six quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein
called a “default period”) that shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Series A Junior Participating
Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each default period, (1) the number of Directors shall be increased by two, effective as of the time of election of such Directors as herein
provided, and (2) the holders of Preferred Stock (including holders of the Series A Junior Participating Preferred Stock) upon which these or like voting rights have been conferred and are exercisable (the “Voting Preferred Stock”) with
dividends in arrears in an amount equal to six quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect such two Directors. 
  
 (i) During any default period, such voting right of the holders of Series A Junior Participating Preferred Stock may be
exercised initially at a special meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders, provided that such voting right shall not be exercised
unless the holders of at least one-third in number of the shares of Voting Preferred Stock outstanding shall be present in person or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of
Voting Preferred Stock of such voting right. At any meeting at which the holders of Voting Preferred Stock shall exercise such voting right initially during an existing default period, they shall have the right, voting as a class, to elect Directors
to fill such vacancies, if any, in the Board of Directors as may then exist up to two Directors or, if such right is exercised at an annual meeting, to elect two Directors. 
  

 A-3 

 If the number that may be so elected at any special meeting does not amount to the required number, the holders of the
Voting Preferred Stock shall, to the extent not inconsistent with the Certificate of Incorporation, have the right to make such increase in the number of Directors as shall be necessary to permit the election by them of the required number. After
the holders of the Voting Preferred Stock shall have exercised their right to elect Directors in any default period and during the continuance of such period, the number of Directors shall not be increased or decreased except by vote of the holders
of Voting Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Junior Participating Preferred Stock. 
  
 (ii) Unless the holders of Voting Preferred Stock shall, during an existing
default period, have previously exercised their right to elect Directors, the Board of Directors may order, or any stockholder or stockholders owning in the aggregate not less than ten percent of the total number of shares of Voting Preferred Stock
outstanding, irrespective of series, may request, the calling of a special meeting of the holders of Voting Preferred Stock, which meeting shall thereupon be called by the Chairman of the Board, the President, a Vice President or the Secretary of
the Corporation. Notice of such meeting and of any annual meeting at which holders of Voting Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii) shall be given to each holder of record of Voting Preferred Stock by mailing a copy
of such notice to him at his last address as the same appears on the books of the Corporation. Such meeting shall be called for a time not earlier than 20 days and not later than 60 days after such order or request or, in default of the calling of
such meeting within 60 days after such order or request, such meeting may be called on similar notice by any stockholder or stockholders owning in the aggregate not less than ten percent of the total number of shares of Voting Preferred Stock
outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the stockholders. 
  
 (iii) In any default period, after the holders of Voting Preferred Stock
shall have exercised their right to elect Directors voting as a class, (x) the Directors so elected by the holders of Voting Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the
expiration of the default period, and (y) any vacancy in the Board of Directors may (except as provided in paragraph (C)(ii) of this Section 3) be filled by vote of a majority of the remaining Directors theretofore elected by the holders of the
class or classes of stock which elected the Director whose office shall have become vacant. References in this paragraph (C) to Directors elected by the holders of a particular class or classes of stock shall include Directors elected by such
Directors to fill vacancies as provided in clause (y) of the foregoing sentence. 
  
 (iv) Immediately upon the expiration of a default period, (x) the right of the holders of Voting Preferred Stock as a class to elect Directors shall cease, (y) the term of any Directors elected by the holders of
Voting Preferred Stock as a class shall terminate and (z) the number of Directors shall be such number as may be provided for in the Certificate of Incorporation or By-Laws irrespective of any increase made pursuant to the provisions of paragraph
(C) of this Section 3 (such number being subject, however, to change thereafter in any manner provided by law or in the Certificate of Incorporation or By-Laws). Any vacancies in the Board of Directors effected by the provisions of clauses (y) and
(z) in the preceding sentence may be filled by a majority of the remaining Directors. 
  

 A-4 

 (D) Except as set forth herein, holders of Series A Junior Participating Preferred Stock shall have no
special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action. 
  
 4. Certain Restrictions. 
  
 (A) Whenever quarterly dividends or other dividends or distributions payable
on the Series A Junior Participating Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Junior Participating Preferred
Stock outstanding shall have been paid in full, the Corporation shall not 
  
 (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred Stock; 
  
 (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or
upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, except dividends paid ratably on the Series A Junior Participating Preferred Stock and all such parity stock on which dividends are payable or in
arrears in proportion to the total amounts to which the holders of all such shares are then entitled; or 
  
 (iii) redeem or purchase or otherwise acquire for consideration any shares of Series A Junior Participating Preferred Stock, or any shares
of stock ranking on a parity with the Series A Junior Participating Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of Series A Junior
Participating Preferred Stock, or to all such holders and the holders of any such shares ranking on a parity therewith, upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights
and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. 
  
 (B) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration
any shares of stock of the Corporation unless the Corporation could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner. 
  
 5. Reacquired Shares. Any shares of Series A Junior Participating Preferred Stock purchased or otherwise acquired by
the Corporation in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a
new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to any conditions and restrictions on issuance set forth herein. 
  

 A-5 

 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation (voluntary or otherwise),
dissolution or winding up of the Corporation, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock
unless, prior thereto, the holders of shares of Series A Junior Participating Preferred Stock shall have received $100 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of
such payment (the “Series A Junior Participating Preferred Stock Liquidation Preference”). Following the payment of the full amount of the Series A Junior Participating Preferred Stock Liquidation Preference, no additional distributions
shall be made to the holders of shares of Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the “Common Adjustment”) equal to the quotient
obtained by dividing (i) the Series A Junior Participating Preferred Stock Liquidation Preference by (ii) the Adjustment Number. Following the payment of the full amount of the Series A Junior Participating Preferred Stock Liquidation Preference and
the Common Adjustment in respect of all outstanding shares of Series A Junior Participating Preferred Stock and Common Stock, respectively, holders of Series A Junior Participating Preferred Stock and holders of shares of Common Stock shall, subject
to the prior rights of all other series of Preferred Stock, if any, ranking prior thereto, receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Series
A Junior Participating Preferred Stock and Common Stock, on a per share basis, respectively. 
  
 (A) In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Junior Participating Preferred Stock Liquidation Preference and the liquidation preferences of all
other series of Preferred Stock, if any, that rank on a parity with the Series A Junior Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective
liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock. 
  
 (B) Neither the merger or consolidation of the Corporation into or with
another corporation nor the merger or consolidation of any other corporation into or with the Corporation shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 6, but the sale, lease or
conveyance of all or substantially all the Corporation’s assets shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 6. 
  
 7. Consolidation, Merger, etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each share of Series A Junior
Participating Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share equal to the Adjustment Number times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the
case may be, into which or for which each share of Common Stock is changed or exchanged. 
  

 A-6 

 8. Redemption. The Corporation, at its option, may redeem shares of the Series A Junior
Participating Preferred Stock in whole at any time and in part from time to time, at a redemption price equal to the Adjustment Number times the current per share market price (as such term is hereinafter defined) of the Common Stock on the date of
the mailing of the notice of redemption, together with unpaid accumulated dividends to the date of such redemption. The “current per share market price” on any date shall be deemed to be the average of the closing price per share of such
Common Stock for the ten consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; provided, however, that in the event that the current per share market price of the Common Stock is determined during a period
following the announcement of (A) a dividend or distribution on the Common Stock other than a regular quarterly cash dividend or (B) any subdivision, combination or reclassification of such Common Stock and the ex-dividend date for such dividend or
distribution, or the record date for such subdivision, combination or reclassification, shall not have occurred prior to the commencement of such ten Trading Day period, then, and in each such case, the current per share market price shall be
properly adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sales price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in
either case as reported in the principal transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange, or, if the Common Stock is not listed or admitted to trading on the New York Stock
Exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading, or, if the Common Stock is not listed or admitted to trading on any national securities exchange but sales price information is
reported for such security, as reported by the National Association of Securities Dealers, Inc. Automated Quotations System (“NASDAQ”) or such other self-regulatory organization or registered securities information processor (as such terms
are used under the Securities Exchange Act of 1934, as amended) that then reports information concerning the Common Stock, or, if sales price information is not so reported, the average of the high bid and low asked prices in the over-the-counter
market on such day, as reported by NASDAQ or such other entity, or, if on any such date the Common Stock is not quoted by any such entity, the average of the closing bid and asked prices as furnished by a professional market maker making a market in
the Common Stock selected by the Board of Directors of the Corporation. If on any such date no such market maker is making a market in the Common Stock, the fair value of the Common Stock on such date as determined in good faith by the Board of
Directors of the Corporation shall be used. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the Common Stock is listed or admitted to trading is open for the transaction of business, or,
if the Common Stock is not listed or admitted to trading on any national securities exchange but is quoted by NASDAQ, a day on which NASDAQ reports trades, or, if the Common Stock is not so quoted, a Monday, Tuesday, Wednesday, Thursday or Friday on
which banking institutions in the State of New York are not authorized or obligated by law or executive order to close. 
  
 (A) In the event that fewer than all the outstanding shares of the Series A Junior Participating Preferred Stock are to be redeemed, the number of shares
to be redeemed shall be determined by the Board of Directors and the shares to be redeemed shall be determined by lot or pro rata as may be determined by the Board of Directors or by any other method that may be determined by the Board of Directors
in its sole discretion to be equitable. 
  

 A-7 

 (B) Notice of any such redemption shall be given by mailing to the holders of the shares of Series A
Junior Participating Preferred Stock to be redeemed a notice of such redemption, first class postage prepaid, not later than the fifteenth day and not earlier than the sixtieth day before the date fixed for redemption, at their last address as the
same shall appear upon the books of the Corporation. Each such notice shall state: (i) the redemption date; (ii) the number of shares to be redeemed and, if fewer than all the shares held by such holder are to be redeemed, the number of such shares
to be redeemed from such holder; (iii) the redemption price; (iv) the place or places where certificates for such shares are to be surrendered for payment of the redemption price; and (v) that dividends on the shares to be redeemed will cease to
accrue on the close of business on such redemption date. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the stockholder received such notice, and failure duly to give
such notice by mail, or any defect in such notice, to any holder of Series A Junior Participating Preferred Stock shall not affect the validity of the proceedings for the redemption of any other shares of Series A Junior Participating Preferred
Stock that are to be redeemed. On or after the date fixed for redemption as stated in such notice, each holder of the shares called for redemption shall surrender the certificate evidencing such shares to the Corporation at the place designated in
such notice and shall thereupon be entitled to receive payment of the redemption price. If fewer than all the shares represented by any such surrendered certificate are redeemed, a new certificate shall be issued representing the unredeemed shares.

  
 The shares of Series A Junior Participating Preferred Stock
shall not be subject to the operation of any purchase, retirement or sinking fund. 
  
 9. Ranking. The Series A Junior Participating Preferred Stock shall rank junior to all other series of the Corporation’s Preferred Stock as to the payment of dividends and the distribution of assets,
unless the terms of any such series shall provide otherwise, and shall rank senior to the Common Stock as to such matters. 
  
 10. Amendment. At any time that any shares of Series A Junior Participating Preferred Stock are outstanding, the Certificate of Incorporation of
the Corporation shall not be amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Junior Participating Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of two-thirds or more of the outstanding shares of Series A Junior Participating Preferred Stock, voting separately as a class. 
  
 11. Fractional Shares. Series A Junior Participating Preferred Stock may be issued in fractions of a share that shall entitle the holder, in
proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Junior Participating Preferred Stock.

 SYNTROLEUM CORPORATION 
  
 This certifies that
                                , or registered assigns, is the registered owner
of the number of Rights set forth above, each of which entitles the owner thereof, subject to the terms, provisions and conditions of the Second Amended and Restated Rights Agreement, dated as of October 24, 2004 as it may from time to time be
supplemented or amended (the “Rights Agreement”), between Syntroleum Corporation, a Delaware corporation (the “Company”), and American Stock Transfer & Trust Company (the “Rights Agent”), to purchase from the
Company at any time prior to 5:00 p.m. (New York, New York time) on October 24, 2014 at the principal office or offices of the Rights Agent designated for such purpose, or its successors as Rights Agent, one one-hundredth of a fully paid,
nonassessable share (a “Fractional Share”) of Series A Junior Participating Preferred Stock, par value $.01 per share (the “Preferred Stock”), of the Company, at a purchase price of $20.83 1/3 per one one-hundredth of a share

thereof) set forth above, and the Purchase Price per Fractional Share set forth above, are the number and Purchase Price as of October 24, 2004, based on the Preferred Stock as constituted at such date. The Company reserves the right to require
prior to the occurrence of a Triggering Event (as such term is defined in the Rights Agreement) that a number of Rights be exercised so that only whole shares of Preferred Stock will be issued. 
  
 From and after the first occurrence of a Triggering Event (as such term is
defined in the Rights Agreement), if the Rights evidenced by this Rights Certificate are beneficially owned by or transferred to (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person (as such terms are defined in the Rights

 B-1 

 Acquiring Person, Associate or Affiliate, or (iii) under certain circumstances specified in the Rights Agreement, a
transferee of a person who, concurrently with or after such transfer, became an Acquiring Person or an Affiliate or Associate of an Acquiring Person, such Rights shall, with certain exceptions, become null and void in the circumstances set forth in
the Rights Agreement, and no holder hereof shall have any rights whatsoever with respect to such Rights from and after the occurrence of such Triggering Event. 
  

As provided in the Rights Agreement, the Purchase Price and the number and kind of shares of Preferred Stock or other securities or assets that may be
purchased upon the exercise of the Rights evidenced by this Rights Certificate are subject to modification and adjustment upon the happening of certain events, including Triggering Events. 
  
 This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are hereby incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of
rights, obligations, duties and immunities hereunder of the Rights Agent, the Company and the holders of the Rights Certificates, which limitations of rights include the temporary suspension of the exercisability of such Rights under the specific
circumstances set forth in the Rights Agreement. Copies of the Rights Agreement are on file at the above-mentioned office of the Rights Agent and are also available upon written request to the Company. 
  
 This Rights Certificate, with or without other Rights Certificates, upon
surrender at the principal office or offices of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of Fractional Shares of Preferred Stock as the Rights evidenced by the Rights Certificate or Rights Certificates surrendered shall have entitled such holder to purchase. If this Rights Certificate shall be exercised in part, the
holder shall be entitled to receive upon surrender hereof another Rights Certificate or Rights Certificates for the number of whole Rights not exercised. 
  
 Subject to the provisions of the Rights Agreement, the Rights evidenced by this Certificate (i) may be redeemed by the Company at its option at a
redemption price of $.01 per Right, payable, at the election of the Company, in cash or shares of Common Stock or such other consideration as the Board of Directors may determine, at any time prior to the earlier of the close of business on (a) the
tenth day following the first public announcement of the occurrence of a Flip-In Event (as such time period may be extended or shortened pursuant to the Rights Agreement) and (b) the Expiration Date (as such term is defined in the Rights Agreement)
or (ii) may be exchanged in whole or in part for shares of Common Stock and/or other equity securities of the Company deemed to have the same value as shares of Common Stock, at any time prior to a person’s becoming the beneficial owner of 50%
or more of the shares of Common Stock outstanding or the occurrence of a Flip-Over Event. 
  
 No fractional shares of Preferred Stock are required to be issued upon the exercise of any Right or Rights evidenced hereby (other than, except as set forth above, fractions that are integral multiples of a Fractional
Share of Preferred Stock, which may, at the election of the Company, be evidenced by depositary receipts), but in lieu thereof a cash payment may be made, as provided in the Rights Agreement. 
  

 B-2 

 No holder of this Rights Certificate, as such, shall be entitled to vote or receive dividends or be
deemed for any purpose the holder of shares of Preferred Stock or of any other securities of the Company that may at any time be issuable on the exercise hereof, nor shall anything contained in the Rights Agreement or herein be construed to confer
upon the holder hereof, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in the Rights Agreement), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by this Rights
Certificate shall have been exercised as provided in the Rights Agreement. 
  
 This Rights Certificate shall not be valid or obligatory for any purpose until it shall have been countersigned by the Rights Agent.

 B-7Amendment No. 3 to Letter Agreement

 Exhibit 10.1 
  
 Mr. Ziad Ghandour 
 Principal 
 TI Capital Management 
 9200 Sunset Blvd 
 Penthouse 2 
 Los Angeles, CA 90069 
  
 Dear Ziad: 
  
 This Amendment No. 3 (the “Amendment”) to our Letter Agreement dated October 3, 2003 (“Letter
Agreement”) between Syntroleum Corporation (“Syntroleum”) and TI Capital Management (“Consultant”, and together with Syntroleum, the “Parties”), as amended by the Letter Agreement dated October 15, 2003 and the
Amendment dated February 2, 2004 to the Letter Agreement, is entered into as of October 25, 2004. 
  
 Syntroleum, Consultant and Mr. Ziad Ghandour hereby agree to amend the terms of the Letter Agreement to add the following thereto: 
  
 Syntroleum will pay Mr. Ziad Ghandour in connection with the closing of a
financing with a Chinese company represented by Bear Stearns & Co. and/or introduced to Syntroleum before September 20, 2005, either (i) subject to stockholder approval in accordance with the requirements of the Nasdaq National Market, a number
of shares of Syntroleum common stock equal to such 1% of net proceeds divided by $5.79 per share (the “Shares”) or (ii) if the stockholder approval provided for in (i) above has not yet been received, an amount of cash equal to the market
value on the date of such closing of the number of shares Mr. Ghandour would have received under (i) above; provided, that such closing occurs by February 1, 2006, or such later date as Syntroleum, in its sole discretion, may designate. Such payment
shall be made promptly after the meeting of stockholders at which the proposal to approve the issuance of the Shares is submitted, as provided for below. For the purpose of clarity the following example is given. If the net proceeds received by
Syntroleum from the financing are $100,000,000 then 1% of such is $1,000,000 which is divided by $5.79 to give the number of shares to be provided to Mr. Ghandour under (i) above or 172,711 shares. In the event that stockholder approval provided for
in (i) above has not been received or given and the market value of one share of Common Stock on the date of the closing of the financing is $10 per share, Mr. Ghandour would receive in lieu of the Shares cash in the amount of $1,727,110.

  
 In connection with any issuance of Shares, Syntroleum and Mr.
Ziad Ghandour shall enter into a Registration Rights Agreement substantially in the form of Exhibit A hereto. 
  
 Syntroleum agrees to use its reasonable commercial efforts to submit a proposal to approve the issuance of the Shares to Mr. Ziad Ghandour at the first
annual or special meeting of its stockholders following the date of this Amendment, the time and place of such annual or special meeting to be determined by Syntroleum in its sole discretion. 
  
 It is understood that Syntroleum will not exercise its right to terminate the
Letter Agreement, as amended, for the purpose of avoiding the payment of cash compensation or issuance of the Shares. However, Syntroleum’s determination of whether to enter into any agreement or to agree that any agreement results in the
payment of cash compensation or issuance of the Shares shall be in Syntroleum’s sole discretion.

 Mr. Ziad Ghandour acknowledges that the Shares referred to herein are “restricted securities”
as such term is defined in Rule 144(a)(3) under the Securities Act of 1933, as amended (the “Securities Act”). He agrees that he has not and will not make any offer, sale or other transfer of the Shares by any means which would not comply
with applicable law or this agreement or which would otherwise impose upon Syntroleum any obligation to satisfy any public filing or registration requirement. He further agrees that he will not offer, sell or transfer the Shares unless: 

 

	 	(a)	there is then in effect a registration statement under the Securities Act covering such proposed disposition (the “Registration Statement”) and such disposition is made in
accordance with the Registration Statement; or 

  

	 	(b)	he shall have notified Syntroleum of the proposed disposition and shall have furnished Syntroleum with a statement of the circumstances surrounding the proposed disposition, and, if
requested by Syntroleum, he shall have furnished Syntroleum with an opinion of counsel, reasonably satisfactory to Syntroleum that such disposition is exempt from registration of such Securities under the Securities Act or any applicable state,
foreign or other securities laws. 

  
 Mr. Ziad
Ghandour acknowledges that Syntroleum is under no obligation to aid him in obtaining any exemption from registration requirements in connection with a proposed disposition. He understands and agrees that any disposition of the Shares in violation of
this Agreement shall be null and void, and that no transfer of the Shares shall be made by Syntroleum or the transfer agent for Syntroleum’s common stock upon Syntroleum’s stock transfer books or records unless and until there has been
compliance with the terms of this agreement, the Securities Act, any applicable state and foreign securities law and any other laws. He agrees that he will not transfer the Securities, other than pursuant to a Registration Statement or in a
transaction that complies with Rule 144, unless the transferee agrees to be bound by the restrictions on transfer contained herein. 
  
 Each certificate representing (i) the Shares and (ii) any other securities issued in respect of the Shares upon any stock split, stock dividend,
recapitalization, merger, consolidation or similar event, shall be stamped or otherwise imprinted with a legend in the following form: 
  
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH
SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SYNTROLEUM RECEIVES AN OPINION OF COUNSEL OR OTHER EVIDENCE REASONABLY ACCEPTABLE TO IT THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS
OF SAID ACT.

 Mr. Ziad Ghandour consents to Syntroleum making a notation on its records and giving instructions to any
transfer agent of Syntroleum’s common stock in order to implement the restrictions on transfer established in this agreement. 
  
 Mr. Ziad Ghandour represents and warrants to Syntroleum as follows: 
  
 (a) Experience; Accredited Investor. He is a sophisticated investor and has experience in evaluating and investing in
private placement transactions of securities in companies similar to Syntroleum so that he is capable of evaluating the merits and risks of his investment in Syntroleum and has the capacity to protect his own interests. Further, he recognizes that
an investment in Syntroleum is highly speculative and involves significant risks (including those identified in the Syntroleum’s filings with the Securities and Exchange Commission) including a complete loss of such investment. In addition, he
is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and has accurately completed the questionnaire attached hereto as Exhibit B. He (i) has no need for liquidity in the investment in
the Shares, (ii) is able to bear the substantial economic risk of an investment in the Shares for an indefinite period and (iii) could afford the complete loss of his investment in the Shares. 
  
 (b) Investment. He is acquiring the Shares for investment for his own
account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof. He has not offered or sold any portion of the Shares to be acquired by him and has no present intention of reselling or
otherwise disposing of any portion of such Shares either currently or after the passage of a fixed or determinable period of time or upon the occurrence or nonoccurrence of any predetermined event or circumstance. He understands that the Shares have
not been registered under the Securities Act or qualified under applicable blue sky or other state securities laws by reason of specific exemptions from the registration provisions of the Securities Act and the qualification provisions of applicable
blue sky and other state securities laws, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of his representations as expressed herein. He understands that no Federal or state
agency has passed upon the Shares or made any finding or determination as to the fairness of the investment or any recommendation or endorsement of the Shares. He acknowledges that the Shares must be held indefinitely unless subsequently registered
under the Securities Act or unless an exemption from such registration is available. He is aware of the provisions of Rule 144 promulgated under the Securities Act, which permit limited resale of securities purchased in a private placement subject
to the satisfaction of certain conditions. In acquiring the Shares, he is acting on his own behalf and is not acting together with any other person or entity for the purpose of acquiring, holding, voting or disposing of the Shares within the meaning
of Section 13(d) of the Securities Exchange Act of 1934, as amended. Unless he has otherwise notified Syntroleum in writing, he is not a broker or dealer of securities, nor is he the beneficial owner of 5% or more of the outstanding shares of
Syntroleum’s 
  

 3 

 common stock. He has not prior to the date hereof directly or indirectly, through related parties, affiliates or
otherwise (a) sold “short” or “short against the box” (as those terms are generally understood) any equity security of Syntroleum; or (b) otherwise engaged in any transaction which involves hedging of its position in, or reducing
of its economic exposure to, the securities of Syntroleum. 
  
 (c) Access to Data. He has read carefully and understands this agreement and has consulted with his own attorney, accountant or investment advisor with respect to the investment contemplated hereby and its suitability for him. He has
received a copy of the Syntroleum’s filings with the Securities and Exchange Commission since January 1, 2004. He has had an opportunity to discuss Syntroleum’s business, management and financial affairs with its management and has had the
opportunity to review Syntroleum’s facilities. He also has had opportunity to ask questions of officers of Syntroleum. 
  
 THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF OKLAHOMA, UNITED STATES OF AMERICA, WITHOUT REGARD TO
CONFLICT OF LAW PROVISIONS THEREOF. 
  
 Except as amended by this
Amendment, the Letter Agreement shall remain in full force and effect. 
  
 This Amendment may be executed in any number of counterparts and by different Parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which taken together shall
constitute but one and the same instrument. Delivery of an executed counterpart of the signature page of this Amendment by facsimile transmission shall be equally as effective as delivery of a manually executed counterpart of this Amendment.
