 Exhibit 10.4 
 SECOND AMENDMENT 
 TO THE 

FEDERAL HOME LOAN MORTGAGE CORPORATION 
 MANDATORY EXECUTIVE DEFERRED BASE SALARY PLAN 
 (As Effective
January 1, 2009) 
 SECOND AMENDMENT TO THE FEDERAL HOME LOAN MORTGAGE CORPORATION MANDATORY EXECUTIVE DEFERRED BASE
SALARY PLAN (the “Plan”) by the FEDERAL HOME LOAN MORTGAGE CORPORATION (the “Corporation”), a corporation organized and existing under the laws of the United States of America. 

W I T N E S S E T H: 
 WHEREAS, the Plan was adopted effective January 1, 2009, and first amended in 2011; 
 WHEREAS, the Corporation now desires to further amend the Plan, to reflect certain changes to the Corporation’s compensation structure effective January 1, 2012; 

WHEREAS, Section 8.1 of the Plan permits the Corporation to amend the Plan; and 

WHEREAS, the appropriate officer of the Corporation has been duly authorized to execute this amendment. 

NOW, THEREFORE, the Plan is amended, as follows, effective January 1, 2012: 

 

	 	1.	Article I (Establishment of the Plan) is hereby amended as follows: 

 

	 	(i)	Section 1.2 (Effective Date), and Section 1.3 (Name) are hereby redesignated as Sections 1.3 and 1.4, respectively. 

 

	 	(ii)	The following new Section 1.2 (Plan Applicability and Automatic Termination) is hereby added, following Section 1.1 (Purpose):

  

	 	“1.2	Plan Applicability and Automatic Termination. 

  

	 	(a)	The Plan is applicable solely to amounts paid as Deferred Base Salary under the Federal Home Loan Mortgage Corporation Executive Management Compensation Program. That
compensation program applied to calendar years prior to 2012. For calendar years beginning on or after January 1, 2012, Executives are not compensated under that program, and do not earn Deferred Base Salary with respect to 2012 or future
years. Therefore, the Plan does not apply to pay earned in 2012 or future years, including pay under the so-called “2012 Executive Management Compensation Program. 

	 	(b)	By operation of this section, the Plan shall terminate automatically as of the earlier of (i) December 31, 2012, or, (ii) the date as of which no further
distributions to Participants will occur.” 

 IN WITNESS WHEREOF, the Corporation has caused this SECOND AMENDMENT TO THE
FEDERAL HOME LOAN MORTGAGE CORPORATION MANDATORY EXECUTIVE DEFERRED BASE SALARY PLAN to be executed by its duly authorized representative this 14th day of June, 2012.

 RIGHTS AGREEMENT 
 RIGHTS AGREEMENT, dated August 6, 2012 (the “Agreement”), between Savient Pharmaceuticals, Inc., a Delaware corporation (the “Company”), and American Stock Transfer &
Trust Company, LLC, a New York limited liability company, as Rights Agent (the “Rights Agent”). 
 W I
T N E S S E T H 
 WHEREAS, on August 6, 2012 the Board of Directors of the Company
(the “Board”) authorized and declared a dividend distribution of one Right for each share of Common Stock (as hereinafter defined) of the Company outstanding at the close of business on August 17, 2012 (the “Record Date”),
and authorized the issuance of one Right (as such number may hereinafter be adjusted pursuant to the provisions of Section 11(i) or Section 11(p) hereof) for each share of Common Stock (as hereinafter defined) that shall become outstanding
between the Record Date (whether originally issued or delivered from the Company’s treasury) and the earlier of the Distribution Date and the Expiration Date and certain additional shares of Common Stock that shall become outstanding after the
Distribution Date as provided in Section 3 of this Agreement, each Right initially representing the right to purchase one one-thousandth of a share of Series A Junior Participating Preferred Stock (as hereinafter defined) having the
rights, powers and preferences set forth in the form of Certificate of Designations attached hereto as Exhibit A, 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 have the meanings indicated: 

(a) “Acquiring Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, shall be
the Beneficial Owner of 15% or more of the shares of Common Stock then outstanding, but shall not include (i) the Company, (ii) any Subsidiary of the Company, (iii) any employee benefit plan of the Company or of any Subsidiary of the
Company, (iv) any Person organized, appointed or established by the Company for or pursuant to the terms of any such plan or (v) an Exempted Person. Notwithstanding the foregoing, (x) no Person shall become an “Acquiring
Person” as the result of an acquisition of Common Stock by the Company which, by reducing the number of shares outstanding, increases the proportionate number of shares beneficially owned by such Person to 15% or more of the shares of Common
Stock then outstanding; provided, however that if a Person shall become the Beneficial Owner of 15% or more of the shares of Common Stock then outstanding as the result of an acquisition of Common Stock by the Company and shall, following written
notice from, or public disclosure by the Company of such share purchases by the Company become the Beneficial Owner of additional Common Stock representing 1% or more of the shares of Common Stock then outstanding (other than as a result of a
dividend or distribution of shares by the Company made on a pro rata basis pursuant to a split or subdivision of the outstanding Common Stock) and shall then beneficially own 15% or more of the shares of Common Stock

 
then outstanding, then such Person shall be deemed to be an “Acquiring Person” and (y) if the Board determines in good faith that a Person who would otherwise be an “Acquiring
Person,” as defined pursuant to the foregoing provisions of this paragraph (a), has become such inadvertently, without any plan or intention to obtain, change or influence the control of the Company, and such Person (without exercising or
retaining any power, including without limitation, voting power with respect to such shares) divests as promptly as practicable (as determined in good faith by the Board), but in any event within fifteen (15) Business Days, following receipt of
written notice from the Company of such event, of Beneficial Ownership of a sufficient number of shares of Common Stock so that such Person would no longer be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this
paragraph (a), then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement unless and until such Person shall again become an “Acquiring Person.” 

(b) “Act” shall mean the Securities Act of 1933, as amended. 

(c) “Affiliate” and “Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 of the
General Rules and Regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as in effect on the date of this Agreement. 
 (d) “Adjustment Shares” shall have the meaning set forth in Section 11(a)(ii). 
 (e) A Person shall be deemed the “Beneficial Owner” and to have “Beneficial Ownership” of, and shall be deemed to “Beneficially Own,” any securities: 

(i) as to which such Person or any of such Person’s Affiliates or Associates is or may be deemed to be the beneficial owner,
directly or indirectly, pursuant to Rules 13d-3 and 13d-5 of the General Rules and Regulations under the Exchange Act, as such Rules are in effect on the date of this Agreement; 

(ii) as to which such Person or any of such Person’s Affiliates or Associates has the right to become the Beneficial Owner (whether
such right is exercisable immediately or only after the passage of time or the occurrence of conditions), directly or indirectly, pursuant to any agreement, arrangement or understanding, whether or not in writing (other than customary agreements
with and between underwriters and selling group members with respect to a bona fide public offering of securities or agreements with or between Persons and the Company with respect to any other bona fide issuance of securities by the Company to such
Persons for resale within forty (40) days, including without limitation pursuant to Section 4(2) of the Act or Rule 144A or Regulation S promulgated under the Act), or upon the exercise of conversion rights, exchange rights, rights (other
than the Rights), warrants or options, or otherwise; 
 (iii) which are Beneficially Owned, directly or indirectly, by any other
Person or any of such other Person’s Affiliates or Associates with which such first Person or any of such first Person’s Affiliates or Associates has any agreement, arrangement or understanding, whether or not in writing, for the purpose
of acquiring, holding, voting (except pursuant to a revocable proxy as described in clause (B) of subsection (iv) of this definition) or disposing of any voting securities of the Company; and 

  
 -2-

 (iv) that such Person or any of such Person’s Affiliates or Associates are deemed to
Constructively Own; provided, however, that a Person shall not be deemed the “Beneficial Owner,” or to have “Beneficial Ownership” of, or to “Beneficially Own,” any security for purposes of this Agreement
(A) solely because such security has been tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered security is accepted for payment or exchange, or
(B) solely because such Person or any of such Person’s Affiliates or Associates has or shares the power to vote or direct the voting of such security pursuant to a revocable proxy or consent given in response to a public proxy or consent
solicitation made to more than ten holders of shares of a class of stock of the Company registered under Section 12 of the Exchange Act and pursuant to, and in accordance with, the applicable provisions of the General Rules and Regulations
under the Exchange Act, except if such power (or the arrangements relating thereto (whether or not in writing)) is then reportable under Item 6 of Schedule 13D under the Exchange Act (or any similar provision of a comparable or successor
statement), or (C) issuable upon exercise of the Rights at any time prior to the occurrence of a Triggering Event or 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) hereof in connection with an
adjustment made with respect to any Original Rights. Notwithstanding the foregoing, no officer or director of the Company shall be deemed to Beneficially Own any securities of any other Person solely by virtue of any actions that such officer or
director takes in such capacity. 
 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)(l)(i) of
the General Rules and Regulations under the Exchange Act. Notwithstanding any other provision in this Section 1(e), no Person shall be deemed to Beneficially Own shares of Common Stock issuable (but not yet issued) upon the conversion of the

clause at the beginning of this Agreement.

however, that if such date is not a Business Day it shall mean 5:00 p.m., New York City time, on the next succeeding Business Day.

Stock in respect of such Synthetic Long Position that is specified in a filing by such Person or any of such Person’s Affiliates or Associates with the SEC or in the documentation evidencing such Synthetic Long Position as the basis upon which
the value or settlement amount of such right, option, derivative or other interest, or the opportunity of the holder of such right, option, derivative or other interest to profit or share in any profit, is to be calculated in whole or in part, and
in any case (or if no such number of shares of Common Stock is specified in any filing or documentation), as determined by the Board in good faith to be the number of shares of Common Stock to which such Synthetic Long Position relates.

 Section 3. Issuance of Rights.

 (a) Until the earlier of (i) the close of business on the tenth (10th) day after the Stock Acquisition Date (or, if the tenth
(10th) day after the Stock Acquisition Date occurs
before the Record Date, the close of business on the Record Date), and (ii) the close of business on the tenth
(10th) day (or such later date as may be determined
by action of the Board prior to such time as any Person becomes an Acquiring Person) after the date that a tender or exchange offer by any Person (other than the Company, any Subsidiary of the Company, any employee benefit plan of the Company or of
any Subsidiary of the Company, or any Person organized, appointed or established by the Company for or pursuant to the terms of any such plan) is first published or sent or given within the meaning of Rule 14d-2 of the General Rules and
Regulations under the Exchange Act, if upon consummation thereof, such Person together with all Affiliates and Associates of such Person, would be the Beneficial Owner of 15% or more of the shares of Common Stock then outstanding, or, in the case of
an Exempted Person, 17.5% or more of the shares of Common Stock then outstanding, (the earlier of (i) and (ii) being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced by the certificates for
the Common Stock registered in the names of the holders of the Common Stock and not by separate certificates, and (y) the Rights will be transferable only in connection with the transfer of the underlying shares of Common Stock (including a
transfer to the Company). As soon as practicable after the Distribution Date, the Rights Agent will send by first-class, insured, postage prepaid mail, to each record holder of the Common Stock as of the close of business on the Distribution Date,
at the address of such holder shown on the records of the Company, one or more rights certificates, in substantially the form of Exhibit B hereto (the “Rights Certificates”), evidencing one Right for each share of Common Stock
so held, subject to adjustment as provided herein. With respect to shares of Common Stock outstanding as of the close of business on the Record Date, until the Distribution Date, the Rights will be evidenced by certificates for such shares of Common
Stock (or if the shares of Common Stock are uncertificated, by registration of the associated shares of Common Stock on the stock transfer books of the Company) and the registered holders of the Common Stock shall also be the registered holders of
the associated Rights. 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 (i) shall, with respect to shares of Common Stock so issued or
sold pursuant to the exercise of stock options or under any employee benefit plan or arrangement, or upon the exercise, conversion or exchange 

  
 -7-

 
of securities granted or issued by the Company prior to the Distribution Date, and (ii) may, in any other case, if deemed necessary or appropriate by the Board, issue Rights Certificates
representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (x) 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 (y) 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. In the event that an adjustment in the number of Rights per share of Common Stock has been made pursuant to Sections 11(i) or 11(p) hereof, at the time of
distribution of the Rights Certificates, the Company shall make the necessary and appropriate rounding adjustments (in accordance with Section 14(a) hereof) so that Rights Certificates representing only whole numbers of Rights are distributed
and cash is paid in lieu of any fractional Rights. As of and after the Distribution Date, the Rights will be evidenced solely by such Rights Certificates. 
 (b) As promptly as practicable following the Record Date, the Company will send a copy of a Summary of Rights to Purchase Preferred Stock, in substantially the form attached hereto as
Exhibit C, by first-class, postage prepaid mail, to each record holder of the Common Stock as of the close of business on the Record Date, at the address of such holder shown on the records of the Company. The failure to send a copy of
the Summary of Rights shall not affect the enforceability of any part of this Rights Agreement or the rights of any holder of the Rights. 
 (c) Rights shall be issued in respect of all shares of Common Stock that are issued after the Record Date but prior to the earlier of the Distribution Date and the Expiration Date. Confirmation and
account statements sent to holders of Common Stock that is uncertificated and registered in book entry form, or, in the case of certificated shares, certificates representing such shares of Common Stock (including, without limitation, certificates
issued upon transfer or exchange of Common Stock) shall also be deemed to be certificates for Rights, and shall bear the following (or a substantially similar) legend: 
 This certificate also evidences and entitles the holder hereof to certain Rights as set forth in the Rights Agreement between Savient Pharmaceuticals, Inc. (the “Company”) and American Stock
Transfer & Trust Company, LLC, (the “Rights Agent”) dated August 6, 2012, as the same may be amended, restated or renewed from time to time (the “Rights Agreement”), the terms of which are hereby incorporated herein
by reference and a copy of which is on file at the principal offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this
certificate. The Company will mail to the holder of this certificate a copy of the Rights Agreement, as in effect on the date of mailing, without charge promptly after receipt of a written request therefor. Under certain circumstances set forth in
the Rights Agreement, Rights issued to, or held by, any Person who is, was or becomes an Acquiring Person or any Affiliate or Associate thereof (as such terms are defined in the Rights Agreement), whether currently held by or on behalf of such
Person or by any subsequent holder, may become null and void. 

  
 -8-

 With respect to certificated Common Stock represented by stock certificates containing the foregoing (or a
substantially similar) legend, until the earlier of (i) the Distribution Date and (ii) the Expiration Date, the Rights associated with such Common Stock shall be evidenced by such certificates alone and registered holders of Common Stock
shall also be the registered holders of the associated Rights. With respect to Common Stock that is uncertificated and registered in book entry form and for which there has been sent a confirmation or account statement containing the foregoing (or a
substantially similar) legend, until the earlier of (i) the Distribution Date and (ii) the Expiration Date, the Rights associated with the Common Stock represented by such book entry registrations shall be represented by such Common Stock
alone, and transfer of any such Common Stock shall also constitute the transfer of Rights associated with such shares of Common Stock. Notwithstanding this Section 3(c), the omission of a legend shall not affect the enforceability of any part
of this Rights Agreement or the rights of any holder of the Rights. 
 Until the earlier of the Distribution Date and the Expiration Date, the
transfer of any certificates representing shares of Common Stock in respect of which Rights have been issued shall also constitute the transfer of the Rights associated with such shares of Common Stock. If the Common Stock issued after the Record
Date but prior to the earlier of the Distribution Date or the Expiration Date shall be uncertificated, the registration of such Common Stock on the stock transfer books of the Company shall evidence the Rights associated with each share of Common
Stock represented thereby. In the event that the Company purchases or acquires any shares of Common Stock after the Record Date but prior to the Distribution Date, any Rights associated with such shares of Common Stock shall be deemed cancelled and
retired so that the Company shall not be entitled to exercise any Rights associated with the shares of Common Stock which are no longer outstanding. 
 Section 4. Form of Rights Certificates. The Rights Certificates (and the forms of election to purchase, certification and assignment to be printed on the reverse thereof) shall each 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 national securities exchange or quotation system on which the
Rights may from time to time be listed or traded (“Trading Regulation”), or to conform to usage. Subject to the provisions of this Agreement, the Rights Certificates, whenever distributed, shall entitle the holders thereof to purchase such
number of one one-thousandths of a share of Preferred Stock as shall be set forth therein at the price set forth therein (such exercise price per one one-thousandth of a share, 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.

 Section 5. Countersignature and Registration. 

(a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, 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 , either manually or by facsimile signature, by the Rights Agent 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 Certificates 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 shall keep or cause to be kept, at its office 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, the Rights 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 7(e) and Section 14 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 Certificates (other than Rights Certificates representing Rights that have become void pursuant to Section 7(e) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up, combined or exchanged for another Rights Certificate or Certificates, entitling the registered holder to purchase a like number of one one-thousandths of a share 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 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 Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or
Certificates to be transferred, split up, combined or exchanged, with the form of assignment and certificate appropriately executed, at the office 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) or Affiliates or Associates thereof as the Company shall reasonably request. Thereupon the Rights Agent
shall, subject to Section 7(e) and Section 14 hereof, 

  
 -10-

 
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 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 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; Expiration Date of Rights. 

(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) and Section 11(a)(iii) 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 executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the aggregate
Purchase Price with respect to the total number of one one-thousandths of a share of Preferred Stock (or other shares, securities, cash or other assets, as the case may be) as to which such surrendered Rights are then exercisable, at or prior to the
earliest of (i) the Final Expiration Date, (ii) the time at which the Rights are redeemed as provided in Section 23 hereof (the “Redemption Date”) and (iii) the time at which such Rights are exchanged as provided in
Section 24 hereof (the earliest of (i), (ii) and (iii) being herein referred to as the “Expiration Date”). 
 (b) The Purchase Price for each one one-thousandth of a share of Preferred Stock pursuant to the exercise of a Right shall initially be $2.50 and shall be subject to adjustment from time to time as
provided in Sections 11 and 13(a) hereof and shall be payable in lawful money of the United States of America in accordance with paragraph (c) below. 
 (c) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to purchase and the certificate duly executed, accompanied by payment, with respect to each Right so
exercised, of the Purchase Price per one one-thousandth of a share of Preferred Stock (or other shares, securities, cash or other assets, as the case may be) to be purchased 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 one one-thousandths of a share of Preferred Stock to be purchased and the Company hereby authorizes its transfer agent to comply with such requests, or (B) if the Company shall have elected to deposit the total number of shares of
Preferred Stock issuable upon exercise of the Rights hereunder with a depositary agent, requisition from the 

  
 -11-

 
depositary agent depositary receipts representing such number of one one-thousandths of a share 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 hereby directs the depositary agent to comply with such requests, (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 bank check or money order payable to the order of the Company. 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) hereof, the Company shall 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. 
 (d) In case the registered holder of any Rights Certificate shall
exercise less 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 Section 11(a)(ii) Event, any Rights Beneficially Owned by (i) an Acquiring Person or an
Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person
(or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring
Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding (whether or not in writing) regarding the transferred Rights or (B) a
transfer which the Board has determined is part of a plan, arrangement or understanding (whether or not in writing) that has as a primary purpose or effect avoidance of this Section 7(e), shall become null and void without any further action
and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. No Rights Certificate shall be issued at any time upon the transfer of any Rights to an Acquiring
Person whose Rights would be void pursuant to the preceding sentence or any Associate or Affiliate thereof or to any nominee of such Acquiring Person, Associate or Affiliate; and any Rights Certificate delivered to the Rights Agent for transfer to
an Acquiring Person whose Rights would be void pursuant to the preceding sentence shall be cancelled. The Company shall use all reasonable efforts to insure that the provisions of this Section 7(e) 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. 

  
 -12-

 (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 transfer or exercise as set forth in this Section 7 unless such registered holder shall have (i) completed and
signed the certificate following the form of assignment or election to purchase set forth on the reverse side of the Rights Certificate surrendered for such assignment or exercise, and (ii) provided such additional evidence of the identity of
the Beneficial Owner (or former Beneficial Owner) or any 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 cancelled form, or, if surrendered to the Rights Agent, shall be cancelled 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 cancelled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such cancelled 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) Subject to the provisions of Section 11(f), the Company covenants and agrees that, from and after such time as the
Rights become exercisable, it will use commercially reasonable efforts to keep reserved and available out of its authorized and unissued shares of Preferred Stock (and, following the occurrence of a Triggering Event, out of its authorized and
unissued shares of Common Stock and/or other securities, as the case may be, the number of shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities, as the case may be) 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 the shares of Preferred Stock (and, following the occurrence of a Section 11(a)(ii) Event, Common Stock and/or other securities, as the case may be) issuable and deliverable upon the
exercise of the Rights may be listed on any national securities exchange or automated quotation system, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance
to be so listed upon official notice of issuance upon such exercise. 
 (c) The Company shall use its best efforts to
(i) file, as soon as practicable following the earliest date after the first occurrence of a Section 11(a)(ii) Event on which the consideration to be delivered by the Company upon exercise of the Rights has been determined in accordance
with Section 11(a)(iii) hereof, or as soon as is required by law following the Distribution Date, as the case may be, a registration statement under the Act, with respect to the securities purchasable upon exercise of the Rights on an
appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, (iii) cause such registration statement to 

  
 -13-

 
remain effective (with a prospectus at all times meeting the requirements of the 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, and (iv) obtain such other regulatory approvals as may be necessary for it to issue securities purchasable upon the exercise of the Rights. 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 ninety (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 or to obtain any other required regulatory
approval (including without limitation any Trading Regulation) in connection with the exercisability of the Rights. 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 unless the
requisite registration or qualification in such jurisdiction shall have been effected or obtained. 
 (d) The Company covenants
and agrees that it will take all such action as may be necessary to ensure that all one one-thousandths of a share of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities, as the case may be)
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 one one-thousandths of a share 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 (i) to pay any transfer tax that may be payable in respect of any transfer or delivery of Rights Certificates to a Person other than, or the issuance or delivery of a
number of one one-thousandths of a share 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 Certificate evidencing Rights surrendered for
exercise or (ii) to issue or deliver any certificates for a number of one one-thousandths of a share 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 one one-thousandths
of a share 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 fractional shares 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 

  
 -14-

 
duly surrendered with the forms of election and certification duly executed 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 securities 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 covered by 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 date of this Agreement (A) declare a dividend on the Preferred Stock payable in shares of Preferred Stock, (B) subdivide the
outstanding Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller number of shares, or (D) issue any shares of its capital stock in a reclassification of the Preferred Stock (including any such reclassification in
connection with a consolidation, merger or share exchange in which the Company is the continuing, surviving or acquiring 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, as the 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, 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; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right; provided, further that if the record date for any such dividend, subdivision, combination or reclassification shall occur prior to the Distribution Date, the Company shall make an appropriate adjustment to the
Purchase Price (taking into account any additional Rights which may be issued as a result of such dividend, subdivision, combination or reclassification), in lieu of adjusting (as described above) the number of shares of Preferred Stock (or Common
Stock and/or other securities, as the case may be) issuable upon exercise of the Rights and, in accordance with Section 3(c), but subject to Sections 11(i) and 11(p), each additional share of Preferred Stock issued in connection with such
dividend, subdivision or reclassification shall have associated with it one Right, so that immediately after such event each share of Preferred Stock (or Common Stock and/or other 

  
 -15-

 
securities, as the case may be) will have exactly one Right associated with it. 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 Section 24 of this Agreement, in the event that any Person, alone or together with its Affiliates or Associates,
becomes an Acquiring Person, then, promptly following the first occurrence of such event, proper provision shall be made so that each holder of a Right (except as provided below and in Section 7(e) hereof) shall thereafter have the right to
receive), upon exercise thereof at the then current Purchase Price in accordance with the terms of this Agreement, in lieu of a number of one one-thousandths of a share of Preferred Stock, such number of shares of Common Stock that equals the result
obtained by (x) multiplying the then current Purchase Price by the then number of one one-thousandths of a share of Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event,
and (y) dividing that product (which, following such first occurrence, shall thereafter be referred to as the “Purchase Price” for each Right and for all purposes of this Agreement) by 50% of the current market price (determined
pursuant to Section 11(d) hereof) per share of Common Stock on the date of such first occurrence (such number of shares, the “Adjustment Shares”). 
 (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 are 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: (A) determine the excess of (1) the value of
the Adjustment Shares issuable upon the exercise of a Right (the “Current Value”) over (2) the Purchase Price (such excess, the “Spread”), and (B) with respect to each Right, make adequate provision to substitute for
the Adjustment Shares, upon 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 which the Board has deemed to have the same value as shares of Common Stock (such shares of preferred stock, “common stock equivalents”)), (4) debt securities of the Company (provided that the Company shall
not agree to issue debt securities if such issuance would constitute an event of default under any of the Company’s then outstanding indebtedness), (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 Board based upon the advice of a nationally recognized investment banking firm selected by the Board; provided, however, if the Company shall not have
made adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the the first occurrence of a Section 11(a)(ii) Event (the “Section 11(a)(ii) 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 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 thirty (30) day period set forth
above may be extended to the extent necessary, but not more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in 

  
 -16-

 
order that the Company may seek shareholder approval for the authorization of such additional shares (such period, as it may be extended in accordance with this sentence until up to ninety
(90) days after the Section 11(a)(ii) Trigger Date, the “Substitution Period”). To the extent that the Company 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 (as determined pursuant to Section 11(d) hereof) per share of the Common Stock on the Section 11(a)(ii) 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 forty-five (45) days after such record date) Preferred Stock (or
shares having 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 (as determined pursuant to Section 11(d)
hereof) 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 which 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 (or into which the convertible securities so to be offered are initially
convertible); provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon exercise of one Right. 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, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes. 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, options or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had
not been fixed. 

  
 -17-

 (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, merger on share exchange in which the Company is the continuing or acquiring 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 (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date, less the fair market value (as determined in good faith by the Board, whose determination shall be described in
a statement filed with the Rights Agent and shall be conclusive for all purposes) 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 (as determined pursuant to Section 11(d) hereof) per share of Preferred Stock on such record date; provided, however, that in no event shall the consideration to be paid upon
the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company to be issued upon exercise of one Right. 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 which 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 on any date
shall be deemed to be the average of the daily closing prices per share of such Common Stock for the thirty (30) consecutive Trading Days (as such term is hereinafter defined) 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 ten
(10) consecutive Trading Days immediately following such date; provided, however, that in the event that the current market price per share of the Common Stock is determined during a period following the announcement by the issuer
of such Common Stock of (A) a dividend or distribution on such Common Stock payable in shares of such Common Stock or securities convertible into shares of such Common Stock (other than the Rights), or (B) any subdivision, combination or
reclassification of such Common Stock, and prior to the expiration of the requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth above, after the ex-dividend date for such dividend or distribution, or the record
date for such subdivision, combination or reclassification, then, and in each such case, the “current market price” shall be properly adjusted to take into account ex-dividend or post-record date trading. The closing price for each day
shall be the last sale 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 consolidated transaction reporting system with
respect to securities listed or admitted to trading on the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading or, if the shares of Common Stock are not listed or admitted to trading on any
national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and the low asked prices in the over-the-counter market, as reported by such 

  
 -18-

 
system then in use, or, if on any such date the shares of Common Stock are not quoted by any such organization, 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. All references in this Section to closing prices, last quoted prices or other stock prices mean prices during regular trading hours, without giving effect to any after-hours or
extended hours trading. If on any such date no market maker is making a market in the Common Stock, the fair value of such shares on such date shall be as determined in good faith by the Board, whose determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes. The term “Trading Day” shall mean a day on which or any national securities exchange on which the shares of Common Stock are listed or admitted to trading is open for
the transaction of business or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, a Business Day. 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, 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 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 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 1,000 (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, which 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 one one-thousandth of a
share of Preferred Stock shall be equal to the “current market price” of one share of Preferred Stock divided by 1,000. 
 (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 one percent (1%) in
the Purchase Price; provided, however, that any adjustments which 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-millionth of a share of Preferred Stock, or hundred-thousandth of a share of Common Stock or other security, 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)(ii) or Section 13(a) hereof, the holder of any Right
thereafter exercised shall become entitled to receive any 

  
 -19-

 
securities other than Preferred Stock, thereafter the number of such other securities 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), (g), (h), (i), (j), (k) and (m), 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 securities; provided, however, that the Company shall not be liable for its inability to reserve and keep available for issuance upon
exercise of the Rights pursuant to Section 11(a)(ii) a number of shares of Common Stock greater than the number then authorized by the Company’s Certificate of Incorporation but not outstanding or reserved for other purposes. 

(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 one one-thousandths of a share of Preferred Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein. 

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as
a result of the calculations made in Sections 11(b) and (c), 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 one
one-thousandths of a share of Preferred Stock (calculated to the nearest ten-millionth) obtained by (i) multiplying (x) the number of one one-thousandths of a share 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 one one-thousandths of a share 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 one
one-thousandths of a share 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 one-hundred- 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 ten (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 

  
 -20-

 
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 one one-thousandths of a share 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 one one-thousandth of a share and
the number of one one-thousandths of a share which 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, of the number of one one-thousandths of a share of Preferred Stock issuable upon exercise of the Rights, the Company shall take any
corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue such number of one one-thousandths of a share of fully paid and nonassessable Preferred Stock 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 one one-thousandths of a share of Preferred Stock and
other capital stock or securities of the Company, if any, issuable upon such exercise over and above the number of one one-thousandths of a share 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 its sole discretion the Board 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 which 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 after the Distribution Date,
(i) consolidate with any other Person (other than a Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary of the Company in a transaction
that complies with Section 11(o) 

  
 -21-

 
hereof), (iii) consummate a share exchange with any other Person (other than a Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), or (iv) sell or
transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole)
to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), if (x) at the time of or immediately after such consolidation, merger,
share exchange or sale there are any charter or bylaw provisions or any rights, warrants or other instruments or securities outstanding or agreements in effect that would substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights or (y) prior to, simultaneously with or immediately after such consolidation, merger, share exchange or sale, the stockholders 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. The Company shall not consummate any consolidation, merger, share exchange sale or transfer
described in clause (i), (ii), (iii) or (iv) of the prior sentence unless prior thereto the Company and such other Person shall have executed and delivered to the Rights Agent a supplemental agreement evidencing compliance with this
Section 11(n). 
 (o) The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted
by Section 24 or Section 27 hereof, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits
intended to be afforded by the Rights. 
 (p) Notwithstanding anything in this Agreement to the contrary, prior to the
Distribution Date, the Company may, in lieu of making any adjustment to the Purchase Price, the number of shares of Common Stock eligible for purchase on exercise of each Right or the number of Rights outstanding, which adjustment would otherwise be
required by Section 11(a)(i), 11(b), 11(c), 11(h) or 11(i), make such other equitable adjustment or adjustments thereto as the Board (whose determination shall be conclusive) deems appropriate in the circumstances and not inconsistent with the
objectives of the Board in adopting this Agreement and such Sections. 
 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 promptly (a) prepare a certificate setting forth such adjustment and a brief statement of the facts accounting
for such adjustment, (b) 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) if such adjustment occurs following a Distribution Date, mail a brief
summary thereof to each holder of a Rights Certificate 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 and shall not be deemed to have
knowledge of any adjustment unless and until it shall have received such certificate. 

  
 -22-

 Section 13. Consolidation, Merger, Share Exchange or Sale or Transfer of Assets or
Earning Power. 
 (a) In the event that, at any time after a Person has become an Acquiring Person, (x) the Company
shall consolidate with, merge with and into, or consummate a share exchange with, any other Person (other than a Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), and the Company shall not be the continuing,
surviving or acquiring corporation of such consolidation, merger or share exchange, (y) any Person (other than a Subsidiary of the Company in a transaction that complies with Section 11(o) hereof) shall consolidate with, or merge with or
into, the Company, and the Company shall be the continuing, surviving, or acquiring corporation of such consolidation, merger, or share exchange and, in connection with such consolidation, merger or share exchange, all or part of the outstanding
shares of Common Stock shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, or (z) the Company shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or
otherwise transfer), in one transaction or a series of related transactions, assets or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons (other than
the Company or any Subsidiary of the Company in one or more transactions each of which complies with Section 11(o) hereof), then, and in each such case, proper provision shall be made so that: (i) 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 then current Purchase Price in accordance with the terms of this Agreement, such number of validly authorized and issued, fully paid,
non-assessable and freely tradable shares of Common Stock of the Principal Party (as such term is hereinafter defined), which shall not be subject to any liens, encumbrances, rights of first refusal or other adverse claims, as shall be equal to the
result obtained by (1) multiplying the then current Purchase Price by the number of one one-thousandths of a share of Preferred Stock for which a Right is exercisable immediately prior to the first occurrence of a Section 13 Event (or, if
a Section 11(a)(ii) Event has occurred prior to the first occurrence of a Section 13 Event, multiplying the number of such one one-thousandths of a share for which a Right was exercisable immediately prior to the first occurrence of a
Section 11(a)(ii) Event by the Purchase Price in effect immediately prior to such first occurrence), and (2) dividing that product (which, following the first occurrence of a Section 13 Event, shall be referred to as the
“Purchase Price” for each Right and for all purposes of this Agreement) by 50% of the current market price (determined pursuant to Section 11(d) hereof) per share of the Common Stock of such Principal Party on the date of
consummation of such Section 13 Event; (ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such Section 13 Event, all the obligations and duties of the Company pursuant to this Agreement;
(iii) the term “Company” shall thereafter be deemed to refer to such Principal Party, it being specifically intended that, subject to clause (v) below, the provisions of Section 11 hereof shall apply only to such Principal
Party following the first occurrence of a Section 13 Event; (iv) 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 (v) the provisions of Section 11(a)(ii) hereof shall be of no effect following the first occurrence of any Section 13 Event. 
 (b) “Principal Party” shall mean 

  
 -23-

 (i) in the case of any transaction described in clause (x) or (y) of the first
sentence of Section 13(a), the Person that is the issuer of any securities into which shares of Common Stock are converted, or for which shares of Common Stock are exchanged, in such merger, consolidation or share exchange, and if no securities
are so issued, the Person that is the other party to such merger, consolidation or share exchange; 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;

 provided, however, that in any such case, (1) if the Common Stock of such Person is not at such time and has not been
continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, and 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) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Stocks of two or more 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) in case 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 ventures 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 such consolidation, merger, share exchange, sale or transfer unless the
Principal Party shall have a sufficient number of authorized shares of its Common Stock which 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 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 any consolidation, merger, share exchange or sale of assets mentioned in paragraph (a) of this Section 13, the Principal Party will 
 (i) prepare and file a registration statement under the 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 Act) until the Expiration Date; 

(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; and 

  
 -24-

 (iii) 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, consolidations, share exchanges or sales or other transfers. In the event that a Section 13 Event shall occur at the same time as, or at any time after, the
occurrence of a Section 11(a)(ii) Event, the Rights which have not theretofore been exercised shall thereafter become exercisable in the manner described in
 Section 13(a). 

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(a)(i), 11(i) or 11(p) hereof, or to distribute Rights Certificates
that evidence 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 current market value of a whole Right. For purposes of this Section 14(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such
fractional Rights would have been otherwise issuable. The closing price of the Rights for any day shall be the last sale 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 consolidated transaction reporting system with respect to securities listed or admitted to trading on the principal national securities exchange on which the Rights are listed or admitted to trading,
or if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and the low asked prices in the over-the-counter market, as reported by such system
then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board. All references
in this Section to closing prices, last quoted prices or other stock prices means prices during regular trading hours, without giving effect to any after-hours or extended hours trading. If on any such date no such market maker is making a market in
the Rights, the fair value of the Rights on such date as determined in good faith by the Board shall be used, which determination shall be described in a statement filed with Rights Agent and shall be conclusive for all purposes. 

(b) The Company shall not be required to issue fractions of shares of Preferred Stock (other than fractions which are integral multiples
of one one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to distribute certificates that evidence fractional shares of Preferred Stock (other than fractions which are integral multiples of one one-thousandth of a share of
Preferred Stock). Fractional shares of Preferred Stock in integral multiples of one one-thousandth of a share of Preferred Stock may, at the election of the Company, be evidenced by depositary receipts; provided, however, that holders of such
depositary receipts shall have all of the designations and the powers, preferences and rights, and the qualifications, limitations and restrictions 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 (other 

  
 -25-

 
than fractions which are integral multiples of one one-thousandth of a share of Preferred Stock), the Company shall 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 current market value of one one-thousandth of a share of Preferred Stock. For purposes of this Section 14(b), the current market value of one one-thousandth of
a share of Preferred Stock shall be one one-thousandth of the closing price of a share of Preferred Stock (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of such exercise. 

(c) The Company shall not be required to issue fractions of shares of Common Stock upon exercise of the Rights or to distribute
certificates that evidence fractional shares of Common Stock. In lieu of fractional shares of Common Stock, the Company shall 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 current market value of a whole share of Common Stock. For purposes of this Section 14(c), the current market value of a whole share of Common Stock shall be the closing price of a share of Common Stock
(as determined pursuant to Section 11(d) hereof) for the Trading Day immediately prior to the date of such exercise. 
 (d)
The holder of a Right by the acceptance of such 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, except the rights of action expressly given to
the Rights Agent in 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 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. 

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 be
evidenced by the certificates of Common Stock registered in the names of the holders thereof (or if the shares of Common Stock are uncertificated, by registration of the associated shares of Common Stock on the stock transfer books of the Company),
and the Rights will be transferable only in connection with the transfer of Common Stock; 

  
 -26-

 (b) after the Distribution Date, the Rights Certificates are transferable only on the
registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates 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 is registered (or, prior to the Distribution Date, each registered holder of Common Stock) 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, subject to the
penultimate sentence of Section 7(e) hereof, shall be required to 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 prevent the issuance of any such
order, decree or ruling and 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 one one-thousandths of a share of Preferred Stock or any other securities of the Company which may at any time be issuable on 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. 

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 disbursements 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 gross negligence, bad faith or willful 

  
 -27-

 
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 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. 
 (c) Notwithstanding anything to the contrary contained herein, the Rights Agent shall not be liable for any delays or failures in performance resulting from acts beyond its reasonable control including,
without limitation, acts of God, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or
retrieval systems, labor difficulties, war, or civil unrest. 
 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 corporate trust business 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, however, 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 a 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 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.

 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 (including, without limitation, the identity of any
Acquiring Person and the determination of “current market price”) 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 the Chairman of the Board, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant
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 only for its own gross 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 or be required to verify the same (except as to its countersignature on such Rights Certificates), 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 adjustment required under the provisions of Section 11, Section 13 or Section 24 hereof or responsible for the manner,
method or amount of any such adjustment 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 receipt of a certificate describing
any such adjustment, delivered pursuant to Section 12); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock or Preferred Stock to be issued
pursuant to this Agreement or any Rights Certificate or as to whether any shares of Common Stock or Preferred Stock will, when so issued, be validly authorized and issued, fully paid and nonassessable. 

(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. 

  
 -29-

 (g) The Rights Agent is hereby authorized and directed to accept instructions with respect
to the performance of its duties hereunder from the Chairman of the Board, the President, any Vice President, the Secretary, any Assistant Secretary, the Treasurer or any Assistant 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 to be taken by it in good faith in accordance with instructions of any such officer. Any application by the Rights Agent for written
instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken or omitted by the Rights Agent with respect to its duties or obligations under this Rights Agreement and the date on and/or
after which such action shall be taken or omitted and the Rights Agent shall not be liable for any action taken or omitted in accordance with a proposal included in any such application on or after the date specified therein (which date shall not be
less than five (5) Business Days after the date any such officer actually receives such application, unless any such officer shall have consented in writing to an earlier date) unless, prior to taking or omitting any such action, the Rights
Agent has received written instructions in response to such application specifying the action to be taken or omitted. 
 (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, however, reasonable care was exercised in the selection and continued employment thereof. 

(j) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably
assured to it. 
 (k) If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the
certificate attached to the form of assignment or form of election to purchase, as the case may be, has not been completed, the Company and the Rights Agent will deem the Beneficial Owner of the rights evidenced by such Rights Certificate to be an
Acquiring Person or an Affiliate or Associate thereof and such assignment or election to purchase will not be honored.

 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 thirty (30) days’ notice in writing mailed to the Company, and, to each transfer agent of the Common Stock and 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 thirty (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 and Preferred Stock, by registered or certified 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 thirty (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 any 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) a Person organized and doing business under the laws of the United States (or of any state of
the United States) in good standing, which is authorized under such laws to exercise corporate trust or 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 $50,000,000 or (b) an Affiliate of a Person described in clause (a) of this sentence. 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 and the Preferred Stock. 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 the Board 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. 

Section 23. Redemption. 
 (a) The Board may, at its option, at any time prior to the earlier of (i) such time as any Person becomes an Acquiring Person and (ii) the Final Expiration Date, redeem all but not less than all
the then outstanding Rights at a redemption price of $0.001 per Right, as such amount may be appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such redemption price being
hereinafter referred to as 

  
 -31-

 
the “Redemption Price”). The redemption of the Rights by the Board may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may
establish. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on the “current market price,” as defined in Section 11(d)(i) hereof, of the Common Stock at the time of redemption) or any
other form of consideration, or any combination of any of the foregoing, deemed appropriate by the Board. 
 (b) Immediately
upon the action of the Board ordering the redemption of the Rights, evidence of which shall have been filed with the Rights Agent and without any further action and without any notice, the right to exercise the Rights shall 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 action of the Board ordering the redemption of the Rights, the Company shall give notice of such redemption to the Rights
Agent and the 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 Transfer Agent for the Common Stock. 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 redemption will state the method by which the payment of the
Redemption Price will be made. 
 (c) In the event of a redemption of the Rights in accordance with this Agreement, the Company
may, at its option, discharge all of its obligations with respect to the Rights by (i) issuing a press release announcing the manner of redemption of the Rights in accordance with this Agreement and (ii) mailing payment of the Redemption
Price to the registered holders of the Rights at their last addresses as they appear on the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the Transfer Agent of the Common Stock, and upon such action,
all outstanding Rights and Right Certificates shall be null and void without any further action by the Company. 
 Section 24.
Exchange. 
 (a) The Board may, at its option, at any time after a Section 11(a)(ii) Event, exchange all or part of
the then outstanding and exercisable Rights (which (i) shall not include Rights that have become void pursuant to the provisions of Section 7(e) hereof, and (ii) shall include, without limitation, any Rights issued after the
Distribution Date) for shares of Common Stock at an exchange ratio of one share of Common Stock per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such exchange ratio
being hereinafter referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board shall not be empowered to effect such exchange at any time after any Person (other than the Company, any Subsidiary of the Company, any
employee benefit plan of the Company or any such Subsidiary, or any entity holding Common Stock for or pursuant to the terms of any such plan), 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. 
 (b) Immediately upon the action of the Board ordering the exchange of any
Rights pursuant to subsection (a) of this Section 24, evidence of which shall have been filed with the 

  
 -32-

 
Rights Agent, 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 equal to the 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 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 shall state the method by which the exchange of shares of Common Stock for
Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights. 
 (c) Following the action of the Board ordering the
exchange of any Rights pursuant to this Section 24, the Company may implement such procedures as it deems appropriate, in its sole discretion, for the purpose of ensuring that the Common Stock (or such other consideration) issuable upon an
exchange pursuant to this Section 24 is not received by holders of Rights that have become null and void pursuant to Section 7(e). Before effecting an exchange pursuant to this Section 24, the Board may direct the Company to enter
into a Trust Agreement in such form and with such terms as the Board shall then approve (the “Trust Agreement”). If the Board so directs, the Company shall enter into the Trust Agreement and shall issue to the trust created by such
agreement (the “Trust”) all or a portion (as designated by the Board) of the shares of Common Stock (or other securities) issuable pursuant to the exchange, and all holders of Rights entitled to receive such shares or securities pursuant
to the exchange shall be entitled to receive such shares or securities (and any dividends paid or distributions made thereon after the date on which such shares are deposited in the Trust) only from the Trust and solely upon compliance with the
relevant terms and provisions of the Trust Agreement. Prior to effecting an exchange and registering shares of Common Stock (or other such securities) in any Person’s name, including any nominee or transferee of a Person, the Company may
require (or cause the trustee of the Trust to require), as a condition thereof, that any holder of Rights provide evidence, including, without limitation, the identity of the Beneficial Owners thereof and their Affiliates and Associates (or former
Beneficial Owners thereof and their Affiliates and Associates) as the Company shall reasonably request in order to determine if such Rights are null and void. If any Person shall fail to comply with such request, the Company shall be entitled
conclusively to deem the Rights formerly held by such Person to be null and void pursuant to Section 7(e) and not transferable or exercisable or exchangeable in connection herewith. Any shares of Common Stock or other securities issued at the
direction of the Board in connection herewith shall be validly issued, fully paid and nonassessable shares of Common Stock or of such other securities (as the case may be), and the Company shall be deemed to have received as consideration for such
issuance a benefit having a value that is at least equal to the aggregate par value of the shares so issued. 
 (d) In the event
that there shall not be sufficient shares of Common Stock or Preferred Stock issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 24, the Company shall take all
such action as may be necessary to authorize additional shares of Common Stock or Preferred Stock for issuance upon exchange of the Rights. 

  
 -33-

 (e) The Company shall not be required to issue fractions of shares of Common Stock or to
distribute certificates which evidence fractional shares of Common Stock. In lieu of such fractional shares of Common Stock, there shall be paid to the registered holders of the Right Certificates 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 current market value of a whole share of Common Stock. For the purposes of this subsection (e), the current market value of a whole share of Common
Stock shall be the closing price per share of Common Stock (as determined pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of exchange pursuant to this Section 24. 

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 Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), to effect
a share exchange with any other Person (other than a Subsidiary of the Company in a transaction that complies with Section 11(o) hereof), or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale
or other transfer), in one transaction or a series of related transactions, of more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of
its Subsidiaries in one or more transactions each of which 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 a
Rights 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, share exchange, sale, 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 twenty (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 twenty (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. 

  
 -34-

 (b) In case a Section 11(a)(ii) Event shall occur, then, in any such case, (i) the
Company shall as soon as practicable thereafter give to each holder of a Rights Certificate, to the extent feasible and 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) hereof, and (ii) all references in the preceding paragraph to Preferred Stock shall be deemed thereafter to refer also to Common Stock and/or, if appropriate, other
securities; provided that the failure to give such notice shall not affect the validity of such consent. 
 Section 26.

 -35-

 
supplement or amend this Agreement without the approval of any holders of Rights in order (i) to cure any ambiguity or (ii) to correct or supplement any provision contained herein which
may be defective or inconsistent with any other provisions herein, provided that no such supplement or amendment shall adversely affect the interests of the holders of Rights as such (other than an Acquiring Person or an Affiliate or Associate of an
Acquiring Person). 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

the extent that the Board determines in good faith that some action will or need be taken pursuant to, or in order to properly give effect to, Sections 7, 11, 21 or 24 or to comply with federal or state securities laws or applicable Trading
Regulations, the Company may suspend the exercisability or exchangeability of the Rights for a reasonable period sufficient to allow it to take such action or comply with such laws or Trading Regulations. In the event of any such suspension, the
Company shall issue as promptly as practicable a public announcement (with prompt written notice to the Rights Agent) stating that the exercisability or exchangeability of the Rights has been temporarily suspended. Notice thereof pursuant to
Section 26 shall not be required. Upon such suspension, any rights of action vested in a holder of Rights shall be similarly suspended.

successors and assigns hereunder. 
 Section 30. Actions by the Board, etc. The Board shall have the exclusive power and
authority to administer this Agreement and to exercise all rights and powers specifically granted to the Board or to the Company, or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right

conclusive and binding on the Company, the Rights Agent, the holders of the Rights and all other parties, and (y) not subject the Board to any liability to the holders of the Rights.

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).

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 determines in its good faith judgment that severing the invalid, void or unenforceable language from this Agreement would adversely affect the purpose or effect of this Agreement, 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
(10th) day following the date of such determination

 FORM OF 
 CERTIFICATE OF DESIGNATIONS 
 OF 

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK 
 OF 
 SAVIENT PHARMACEUTICALS, INC. 

 
  
 Savient Pharmaceuticals, Inc., a corporation organized and existing under the laws of the State of Delaware (hereinafter called the “Corporation”), hereby certifies that the following resolution
was adopted by the Board of Directors of the Corporation at a meeting duly called and held on August 6, 2012: 
 RESOLVED: That pursuant to
the authority granted to and vested in the Board of Directors of the Corporation (hereinafter called the “Board”) in accordance with the provisions of the Certificate of Incorporation, as amended, the Board hereby creates a series of
Preferred Stock, $0.01 par value per share (the “Preferred Stock”), of the Corporation and hereby states the designation and number of shares, and fixes the relative rights, preferences and limitations thereof as follows: 

Series A Junior Participating Preferred Stock: 
 Section 1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” (the “Series A Preferred Stock”)
and the number of shares constituting the Series A Preferred Stock shall be One Hundred Fifty Thousand (150,000). Such number of shares may be increased or decreased by resolution of the Board prior to issuance; provided, that no decrease shall
reduce the number of shares of Series A Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, rights or warrants or upon the
conversion of any outstanding securities issued by the Corporation convertible into Series A Preferred Stock. 
 Section 2.
Dividends and Distributions. 
 (A) Subject to the rights of the holders of any shares of any series of Preferred Stock
(or any similar stock) ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred Stock, in preference to the holders of Common Stock, $0.01 par value per share (the
“Common Stock”), of the Corporation, and of any other junior stock, shall be entitled to receive, when, as and if declared by the Board out of funds of the Corporation legally available for the payment of dividends, quarterly dividends
payable in 

  
 A-1

 
cash on the last day of each fiscal quarter of the Corporation 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 Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $10 or (b) subject to the provision
for adjustment hereinafter set forth, 1,000 times the aggregate per share amount of all cash dividends, and 1,000 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 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 Preferred Stock (but only to the extent that such dividends do not result in an event of default under any of the Corporation’s then
outstanding indebtedness). In the event the Corporation shall at any time declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount 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. In the event the Corporation shall at any time declare or pay any dividend on the Series A Preferred Stock payable in
shares of Series A Preferred Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Series A Preferred Stock (by reclassification or otherwise than by payment of a dividend in shares of Series A Preferred Stock)
into a greater or lesser number of shares of Series A Preferred Stock, then in each such case the amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under clause (b) of the first sentence
of this Section 2(A) shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Series A Preferred Stock that were outstanding immediately prior to such event and the denominator of which is
the number of shares of Series A Preferred Stock outstanding immediately after such event. 
 (B) The Corporation shall declare
a dividend or distribution on the Series A Preferred Stock as provided in paragraph (A) of this Section immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock) and
the Corporation shall pay such dividend or distribution on the Series A Preferred Stock before the dividend or distribution declared on the Common Stock is paid or set apart; 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 $10 per share on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date (but only to the extent that such dividends do not result in an event of default under any of the Corporation’s then outstanding indebtedness). 

  
 A-2

 (C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A
Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares, 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 Preferred Stock
entitled to receive a quarterly dividend and before such Quarterly Dividend 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 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 may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be not more
than sixty (60) days prior to the date fixed for the payment thereof. 
 Section 3. Voting Rights. The holders of
shares of Series A Preferred Stock shall have the following voting rights: 
 (A) Subject to the provision for adjustment
hereinafter set forth, each share of Series A Preferred Stock shall entitle the holder thereof to 1,000 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time declare or
pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of
Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the number of votes per share to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by
multiplying such 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. In the event the Corporation shall at any time declare or pay any dividend on the Series A Preferred Stock payable in shares of Series A Preferred Stock, or effect a subdivision, combination or consolidation of the outstanding
shares of Series A Preferred Stock (by reclassification or otherwise than by payment of a dividend in shares of Series A Preferred Stock) into a greater or lesser number of shares of Series A Preferred Stock, then in each such case the number of
votes per share to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Series A Preferred
Stock that were outstanding immediately prior to such event and the denominator of which is the number of shares of Series A Preferred Stock outstanding immediately after such event. 

(B) Except as otherwise provided herein, in the Certificate of Incorporation or by law, the holders of shares of Series A Preferred Stock
and the holders of shares of Common Stock and any other capital stock of the Corporation having general voting rights shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. 

  
 A-3

 (C) (i) If at any time dividends on any Series A Preferred Stock shall be in arrears in an
amount equal to six quarterly dividends thereon, the holders of the Series A Preferred Stock, voting as a separate series from all other series of Preferred Stock and classes of capital stock, shall be entitled to elect two members of the Board in
addition to any Directors elected by any other series, class or classes of securities and the authorized number of Directors will automatically be increased by two. Promptly thereafter, the Board of the Corporation shall, as soon as may be
practicable, call a special meeting of holders of Series A Preferred Stock for the purpose of electing such members of the Board. Such special meeting shall in any event be held within forty-five (45) days of the occurrence of such arrearage.

 (ii) During any period when the holders of Series A Preferred Stock, voting as a separate series, shall be entitled and shall
have exercised their right to elect two Directors, then, and during such time as such right continues, (a) the then authorized number of Directors shall be increased by two, and the holders of Series A Preferred Stock, voting as a separate
series, shall be entitled to elect the additional Directors so provided for, and (b) each such additional Director shall not be a member of any existing class of the Board, but shall serve until the next annual meeting of stockholders for the
election of Directors, or until his successor shall be elected and shall qualify, or until his right to hold such office terminates pursuant to the provisions of this Section 3(C). 

(iii) A Director elected pursuant to the terms hereof may be removed with or without cause by the holders of Series A Preferred Stock
entitled to vote in an election of such Director. 
 (iv) If, during any interval between annual meetings of stockholders for
the election of Directors and while the holders of Series A Preferred Stock shall be entitled to elect two Directors, there is no such Director in office by reason of resignation, death or removal, then, promptly thereafter, the Board shall call a
special meeting of the holders of Series A Preferred Stock for the purpose of filling such vacancy and such vacancy shall be filled at such special meeting. Such special meeting shall in any event be held within forty-five (45) days of the
occurrence of such vacancy. 
 (v) At such time as the arrearage is fully cured, and all dividends accumulated and unpaid on any
shares of Series A Preferred Stock outstanding are paid, and, in addition thereto, at least one regular dividend has been paid subsequent to curing such arrearage, the term of office of any Director elected pursuant to this Section 3(C), or his
successor, shall automatically terminate, and the authorized number of Directors shall automatically decrease by two, the rights of the holders of the shares of the Series A Preferred Stock to vote as provided in this Section 3(C) shall cease,
subject to renewal from time to time upon the same terms and conditions, and the holders of shares of the Series A Preferred Stock shall have only the limited voting rights elsewhere herein set forth. 

(D) Except as set forth herein, or as otherwise provided by law, holders of Series A 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. 

  
 A-4

 Section 4. Certain Restrictions. 

(A) Whenever quarterly dividends or other dividends or distributions payable on the Series A 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 Preferred Stock outstanding shall have been paid in full, the Corporation shall not: 

(i) declare or pay dividends, or make any other distributions, on any shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock; 
 (ii) declare or pay dividends, 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 Preferred Stock, except dividends paid ratably on the Series A 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; 
 (iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock,
provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such junior stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution, liquidation or
winding up) to the Series A Preferred Stock; or 
 (iv) redeem or purchase or otherwise acquire for consideration any shares of
Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board) to all holders of such shares upon such
terms as the Board, 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. 

Section 5. Reacquired Shares. Any shares of Series A Preferred Stock purchased or otherwise acquired by the Corporation in any
manner whatsoever shall be retired and cancelled 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 subject to the conditions and restrictions on issuance set forth herein, in the Certificate of Incorporation, or in any other Certificate of Designations creating a series of Preferred Stock or any similar stock or as otherwise required by
law. 

  
 A-5

 Section 6. Liquidation, Dissolution or Winding Up. 

(A) Upon any liquidation, dissolution or winding up of the Corporation, no distribution shall be made (1) to the holders of shares
of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall have received $1,000 per share, plus an
amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, provided that the holders of shares of Series A Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000 times the aggregate amount to be distributed per share to holders of shares of Common Stock, or (2) to the holders of shares of stock ranking on a parity (either as
to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except distributions made ratably on the Series A Preferred Stock and all such parity stock in proportion to the total amounts to which the holders of
all such shares are entitled upon such liquidation, dissolution or winding up. 
 (B) Neither the consolidation, merger or other
business combination of the Corporation with or into any other corporation nor the sale, lease, exchange or conveyance of all or any part of the property, assets or business of the Corporation shall be deemed to be a liquidation, dissolution or
winding up of the Corporation for purposes of this Section 6. 
 (C) In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of
Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the aggregate amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under the proviso in
clause (1) of paragraph (A) of this Section 6 shall be adjusted by multiplying such amount 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. In the event the Corporation shall at any time declare or pay any dividend on the Series A Preferred Stock payable in shares of Series A Preferred
Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Series A Preferred Stock (by reclassification or otherwise than by payment of a dividend in shares of Series A Preferred Stock) into a greater or lesser number
of shares of Series A Preferred Stock, then in each such case the aggregate amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under the proviso in clause (1) of paragraph (A) of
this Section 6 shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Series A Preferred Stock that were outstanding immediately prior to such event and the denominator of which is the
number of shares of Series A Preferred Stock outstanding immediately after such event. 
 Section 7. Consolidation, Merger,
etc. Notwithstanding anything to the contrary contained herein, 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 

  
 A-6

 
Series A Preferred Stock shall at the same time be similarly exchanged or changed into an amount per share, subject to the provision for adjustment hereinafter set forth, equal to 1,000 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. In the event the Corporation shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision, combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of Series A Preferred Stock shall be adjusted by multiplying
such amount 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. In the event the Corporation shall at any time declare or pay any dividend on the Series A Preferred Stock payable in shares of Series A Preferred Stock, or effect a subdivision, combination or consolidation of the outstanding shares of
Series A Preferred Stock (by reclassification or otherwise than by payment of a dividend in shares of Series A Preferred Stock) into a greater or lesser number of shares of Series A Preferred Stock, then in each such case the amount set forth in the
first sentence of this Section 7 with respect to the exchange or change of shares of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Series A Preferred Stock
that were outstanding immediately prior to such event and the denominator of which is the number of shares of Series A Preferred Stock outstanding immediately after such event. 

Section 8. No Redemption. The shares of Series A Preferred Stock shall not be redeemable. 

Section 9. Rank. The Series A Preferred Stock shall rank, with respect to the payment of dividends and the distribution of assets,
junior to all series of any other class of the Preferred Stock issued either before or after the issuance of the Series A Preferred Stock, unless the terms of any such series shall provide otherwise. 

Section 10. Amendment. At such time as any shares of Series A Preferred Stock are outstanding, the Certificate of Incorporation,
as amended, 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 Preferred Stock so as to affect them adversely without the affirmative vote of the
holders of at least two-thirds of the outstanding shares of Series A Preferred Stock, voting together as a single class. 

Section 11. Fractional Shares. Series A Preferred Stock may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and have the benefit of all other rights of holders of Series A Preferred Stock.

 SUMMARY OF RIGHTS TO 
 PURCHASE PREFERRED STOCK 
 On August 6, 2012, the Board of Directors of Savient
Pharmaceuticals, Inc. (the “Company”), declared a dividend of one Right for each outstanding share of the Company’s Common Stock to stockholders of record at the close of business on August 17, 2012 (the “Record Date”).
Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, $0.01 par value per share (the “Preferred Stock”), at a Purchase Price of $2.50 in cash,
subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement dated August 6, 2012 (the “Rights Agreement”) between the Company and American Stock Transfer & Trust Company, LLC, as Rights
Agent. 
 Initially, the Rights are not exercisable and will be attached to all certificates representing outstanding shares of Common Stock (or
in the case of uncertificated shares of Common Stock, by such Common Stock alone), and no separate Rights Certificates will be distributed. The Rights will separate from the Common Stock, and the Distribution Date will occur, upon the earlier of
(i) ten (10) days following the later of (a) the first date of a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired, or obtained the right to acquire,
beneficial ownership of 15% or more of the outstanding shares of Common Stock, or, in the case of an Exempted Person (as such term is defined in the Rights Agreement), 17.5% or more of the outstanding shares of Common Stock, or the disclosure of
facts indicating that an Acquiring Person has become such, and (b) the first date on which an executive officer of the Company has actual knowledge that an Acquiring Person has become such (the “Stock Acquisition Date”), and
(ii) ten (10) days following the commencement of a tender offer or exchange offer that would result in a person or group beneficially owning 15% or more of the outstanding shares of Common Stock, or, in the case of an Exempted Person,
17.5% or more of the outstanding shares of Common Stock. No person or entity shall be deemed to beneficially own shares of Common Stock issuable (but not yet issued) upon the conversion of the Company’s 4.75% Convertible Senior Notes due 2018.
The Distribution Date may be deferred in certain circumstances by the Board of Directors. In addition, certain inadvertent acquisitions will not trigger the occurrence of the Distribution Date. Until the Distribution Date (or earlier redemption or
expiration of the Rights), (i) the Rights will be evidenced by the Common Stock certificates outstanding on the Record Date (or in the case of uncertificated shares of Common Stock, by the registration of such shares on the transfer books of
the Company), together with this Summary of Rights, or by new Common Stock certificates issued after the Record Date (or in the case of uncertificated shares, by registration of such shares on the transfer books of the Company), (ii) any new
Common Stock certificates issued after the Record Date (or in the case of uncertificated shares, confirmation and account statements sent to holders of Common Stock after the Record Date) shall contain a notation incorporating the Rights Agreement
by reference, and (iii) the Rights will be transferred with and only with such Common Stock. 

  
 C-1

 The Rights are not exercisable until the Distribution Date and will expire upon the close of business on the
earlier of (i) the close of business on August 6, 2015 or (ii) the close of business on August 6, 2013 if the Stockholder Approval (as defined in the Rights Agreement) shall not have been obtained by the close of business on such
date (such earlier date, the “Final Expiration Date”), unless earlier redeemed or exchanged as described below. As soon as practicable after the Distribution Date, separate Rights Certificates will be mailed to holders of record of the
Common Stock as of the close of business on the Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. 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 (i) shall, with respect to shares of Common Stock so issued or sold pursuant to the exercise of stock options or under any employee benefit plan or arrangement, or upon the
exercise, conversion or exchange of securities granted or issued by the Company prior to the Distribution Date, and (ii) may, in any other case, if deemed necessary or appropriate by the Board, issue Rights Certificates representing the
appropriate number of Rights in connection with such issuance or sale, subject to certain exceptions. 
 In the event that any Person becomes an
Acquiring Person, then, promptly following the first occurrence of such event, each holder of a Right (except as provided below and in Section 7(e) of the Rights Agreement) shall thereafter have the right to receive, upon exercise, that number
of shares of Common Stock (or, in certain circumstances, cash, property or other securities of the Company) which equals the exercise price of the Right divided by 50% of the current market price (as defined in the Rights Agreement) per share of
Common Stock at the date of the occurrence of such event. Notwithstanding any of the foregoing, following the occurrence of such event, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned
by any Acquiring Person will be null and void. The event summarized in this paragraph is referred to as a “Section 11(a)(ii) Event.” 

For example, at an exercise price of $2.50 per Right, each Right not owned by an Acquiring Person (or by certain related parties) following a
Section 11(a)(ii) Event would entitle its holder to purchase for $2.50 such number of shares of Common Stock (or other consideration, as noted above) as equals $2.50 divided by one-half of the current market price (as defined in the Rights
Agreement) of the Common Stock. Assuming that the Common Stock had a market price of $1.25 per share at such time, the holder of each valid Right would be entitled to purchase four shares of Common Stock, having a market value of 4 x $1.25, or
$5.00, for $2.50. 
 In the event that, at any time after any Person becomes an Acquiring Person, (i) the Company is consolidated with, or
merged with and into, or consummates a share exchange with, another entity and the Company is not the surviving or acquiring entity of such consolidation, merger or share exchange or if the Company is the surviving entity, but shares of its
outstanding Common Stock are changed or exchanged for stock or securities (of any other person) or cash or any other property, or (ii) more than 50% of the Company’s assets or earning power is sold or transferred, each holder of a Right
(except Rights which previously have been voided as set forth above) shall thereafter have the right to receive, upon exercise, that number of shares of common stock of the acquiring company which equals the exercise price of the Right divided by
50% of the 

  
 C-2

 
current market price (as defined in the Rights Agreement) of such common stock at the date of the occurrence of the event. The events summarized in this paragraph are referred to as “Section
13 Events.” A Section 11(a)(ii) Event and Section 13 Events are collectively referred to as “Triggering Events.” 
 For
example, at an exercise price of $2.50 per Right, each valid Right following a Section 13 Event would entitle its holder to purchase for $2.50 such number of shares of common stock of the acquiring company as equals $2.50 divided by one-half of
the current market price (as defined in the Rights Agreement) of such common stock. Assuming that such common stock had a market price of $0.625 per share at such time, the holder of each valid Right would be entitled to purchase eight shares of
common stock of the acquiring company, having a market value of 8 x $0.625 or $5.00, for $2.50. 
 At any time after the occurrence of a
Section 11(a)(ii) Event, when no person owns a majority of the Common Stock, the Board of Directors of the Company may exchange the Rights (other than Rights owned by such Acquiring Person which have become void), in whole or in part, at an
exchange ratio of one share of Common Stock, or one one-thousandth of a share of Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per Right (subject to
adjustment). 
 The Purchase Price payable, and the number of units of Preferred Stock or other securities or property issuable, upon exercise
of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Preferred Stock, (ii) if holders of the Preferred Stock are
granted certain rights or warrants to subscribe for Preferred Stock or convertible securities at less than the then-current market price (as defined in the Rights Agreement) of the Preferred Stock, or (iii) upon the distribution to holders of
the Preferred Stock of evidences of indebtedness or assets (excluding regular periodic cash dividends paid out of earnings or retained earnings) or of subscription rights or warrants (other than those referred to above). The number of Rights
associated with each share of Common Stock is also subject to adjustment in the event of a stock split of the Common Stock or a stock dividend on the Common Stock payable in Common Stock or subdivisions, consolidations or combinations of the Common
Stock occurring, in any such case, prior to the Distribution Date. 
 With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase Price. No fractional shares of Preferred Stock (other than fractions which are integral multiples of one one-thousandth of a share of Preferred Stock) will be issued and, in
lieu thereof, an adjustment in cash will be made based on the market price of the Preferred Stock on the last trading date prior to the date of exercise. 
 Preferred Stock purchasable upon exercise of the Rights will not be redeemable. Each share of Preferred Stock will be entitled to receive, when, as and if declared by the Board of Directors, a minimum
preferential quarterly dividend payment of $10 per share or, if greater, an aggregate dividend of 1,000 times the dividend declared per share of Common Stock. In the event of 

  
 C-3

 
liquidation, the holders of the Preferred Stock will be entitled to a minimum preferential liquidation payment of $1,000 per share, plus an amount equal to accrued and unpaid dividends, and will
be entitled to an aggregate payment of 1,000 times the payment made per share of Common Stock. Each share of Preferred Stock will have 1,000 votes, voting together with the Common Stock. In the event of any merger, consolidation or other transaction
in which Common Stock is changed or exchanged, each share of Preferred Stock will be entitled to receive 1,000 times the amount received per share of Common Stock. These rights are protected by customary antidilution provisions. Because of the
nature of the Preferred Stock’s dividend, liquidation and voting rights, the value of one one-thousandth of a share of Preferred Stock purchasable upon exercise of each Right should approximate the value of one share of Common Stock.

 At any time prior to the earlier of such time as any Person becomes an Acquiring Person and the Final Expiration Date, the Company may redeem
the Rights in whole, but not in part, at a price of $0.001 per Right (the “Redemption Price”), payable in cash or stock. Immediately upon the redemption of the Rights or such earlier time as established by the Board in the resolution
ordering the redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. 
 Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. Although the
distribution of the Rights should not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Common Stock (or other
consideration) of the Company or for common stock of the acquiring company as set forth above. 
 Any provision of the Rights Agreement may be
amended by the Board prior to such time as the Rights are no longer redeemable. After the Rights are no longer redeemable, the Rights Agreement shall not be supplemented or amended in any manner that would adversely affect the interests of the
holders of Rights (other than Rights of Acquiring Persons and their transferees that have become null and void pursuant to the Rights Agreement). 
 The Rights are intended to protect the stockholders of the Company in the event of an unfair or coercive offer to acquire the Company and to provide the Board with adequate time to evaluate unsolicited
offers. The Rights may have anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Company without conditioning the offer on a substantial number of Rights being acquired. The Rights
should not interfere with any merger , share exchange or other business combination approved by the Board. 
 A copy of the Rights Agreement has
been filed with the Securities and Exchange Commission as an Exhibit to the Company’s Current Report on Form 8-K dated August 7, 2012. A copy of the Rights Agreement is available free of charge from the Company. This summary description of
the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, which is incorporated herein by reference.
