2.      Company

not impair in any material respect the consummation of the Company’s obligations hereunder or reasonably be expected to have
a material adverse effect on the financial position, stockholders’ equity or results of operations of the Company and its
subsidiaries, taken as a whole.

 

3.     
Representations of the Seller. In connection with the transactions contemplated hereby, the Seller represents and warrants
to the Company that:

 

(a)         
Seller is duly organized and existing under the laws of its state of organization.

 

(b)        
All consents, approvals, authorizations and orders necessary for the execution and delivery by the Seller of this Agreement and
for the sale and delivery of the Repurchase Shares to be sold by the Seller hereunder, have been obtained; and Seller has full
right, power and authority to enter into this Agreement and to sell, assign, transfer and deliver the Repurchase Shares to be sold
by Seller hereunder, except for such consents, approvals, authorizations and orders as would not impair in any material respect
the consummation of the Seller’s obligations hereunder.

 

     

     

    

 

(c)         
This Agreement has been duly authorized, executed and delivered by the Seller and constitutes a valid and binding agreement of
Seller, enforceable in accordance with its terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency,
reorganization or other laws affecting enforcement of creditors’ rights or by general equitable principles.

 

(d)        
The sale of the Repurchase Shares to be sold by the Seller hereunder and the compliance by Seller with all of the provisions of
this Agreement and the consummation of the transactions contemplated hereby (i) will not conflict with or result in a breach
or violation of any of the terms or provisions of, or constitute a default under, any statute, indenture, mortgage, deed of trust,
loan agreement or other agreement or instrument to which Seller is a party or by which the Seller is bound or to which any of the
property or assets of the Seller is subject, (ii) nor will such action result in any violation of the provisions of (x) any
organizational or similar documents pursuant to which Seller was formed or (y) any statute or any order, rule or regulation
of any court or governmental agency or body having jurisdiction over Seller or the property of Seller.

 

(e)         
As of the date hereof and immediately prior to the delivery of the Repurchase Shares to the Company at the Closing, Seller holds
good and valid title to the Repurchase Shares or a securities entitlement in respect thereof, and holds, and will hold, such Repurchase
Shares free and clear of all liens, encumbrances, equities or claims; and, upon delivery of such Repurchase Shares and payment
therefor pursuant hereto, assuming that the Company has no notice of any adverse claims within the meaning of Section 8-105
of the Delaware Uniform Commercial Code as in effect in the State of Delaware from time to time (the “UCC”),
the Company will acquire good and valid title to the Repurchase Shares, free and clear of all liens, encumbrances, equities or
claims, as well as a valid security entitlement (within the meaning of Section 8-102(a)(17) of the UCC) to such Repurchase
Shares purchased by the Company, and no action (whether framed in conversion, replevin, constructive trust, equitable lien or other
theory) based on an adverse claim (within the meaning of Section 8-105 of the UCC) to such security entitlement may be asserted
against the Company.

 

(f)         
The Seller (either alone or together with its advisors) has such knowledge and experience in financial or business matters that
it is capable of evaluating the merits and risks of the Repurchase Transaction. Seller has had the opportunity to ask questions
and receive answers concerning the terms and conditions of the Repurchase Transaction and the Repurchase Shares and has had full
access to such other information concerning the Repurchase Shares and the Company as it has requested. Seller has received all
information that it believes is necessary or appropriate in connection with the Repurchase Transaction. Seller is an informed and
sophisticated party and has engaged, to the extent Seller deems appropriate, expert advisors experienced in the evaluation of transactions
of the type contemplated hereby. Seller acknowledges that it has not relied upon any express or implied representations or warranties
of any nature made by or on behalf of the Company, whether or not any such representations, warranties or statements were made
in writing or orally, except as expressly set forth for the benefit of Seller in this Agreement.

 

     

     

    

 

(g)        
The Seller has received and carefully reviewed the Annual Report of the Company on Form 10-K for the fiscal year ended December
31, 2014 and all subsequent public filings of the Company with the Securities and Exchange Commission (the “SEC”),
other publicly available information regarding the Company, and such other information that it and its advisers deem necessary
to make its decision to proceed with the Repurchase Transaction.

 

(h)        
Seller acknowledges and understands that the Company and its officers and affiliates may possess material non-public information
not known to Seller that may impact the value of the Securities (the “Information”), that the Company is unable
to disclose to Seller, including without limitation, (i) information received by principals and employees of the Company in their
capacities as directors, officers, significant stockholders and/or affiliates of the Company, (ii) information otherwise received
from the Company on a confidential basis, and (iii) information received on a privileged basis from the attorneys and financial
advisers representing the Company and its Board. Seller understands, based on its experience, the disadvantage to which Seller
is subject due to the disparity of information between Seller and the Company. Notwithstanding this, Seller has deemed it appropriate
to engage in the Repurchase Transaction.

 

(i)          
Seller agrees that the Company Releasees (as defined below) shall have no liability to any Seller Releasor (as defined below),
whatsoever due to or in connection with the Company’s use or non-disclosure of the Information, and Seller hereby irrevocably
waives any claims that it might have based on the failure of the Company or any of its affiliates to disclose the Information,
and Seller hereby irrevocably waives any claims that it might have based on any such acts or omissions.

 

4.     
Mutual Release of All Claims.

 

(a)         
Release by the Company. The Company, on behalf of itself and its successors, affiliates, subsidiaries, officers, directors,
partners, members, managing members, managers, trustees, beneficiaries, employees, agents, representatives, attorneys and any other
advisors or consultants (the “Company Releasors”), hereby do remise, release and forever discharge, and covenant
not to sue or take any steps to further any claim, action or proceeding against the Seller and its respective successors, affiliates,
subsidiaries, officers, directors, partners, members, managing members, managers, trustees, beneficiaries, employees, agents, representatives,
attorneys and any other advisors or consultants (the “Seller Releasees”), and each of them, from and in respect
of any and all claims and causes of action, whether based on any federal, state or foreign law or right of action, direct, indirect
or representative in nature, foreseen or unforeseen, matured or unmatured, known or unknown, which all or any of the Company Releasors
have, had or may have against the Seller Releasees, or any of them, of any kind, nature or type whatsoever, up to the date of this
Agreement, except that the foregoing release does not release any rights and duties under this Agreement or any claims the Company
Releasors may have for the breach of any provisions of this Agreement.

 

(b)        
Release by the Seller. Seller, on behalf of itself and its respective successors, affiliates, subsidiaries, officers, directors,
partners, members, managing members, managers, trustees, beneficiaries, employees, agents, representatives, attorneys and any other
advisors or consultants (the “Seller Releasors”), hereby do remise, release and forever discharge, and covenant

officers, directors, partners, members, managing members, managers, trustees, beneficiaries, employees, agents, representatives,

or representative in nature, foreseen or unforeseen, matured or unmatured, known or unknown, which the Seller has, had or may have
against the Company Releasees, or any of them, of any kind, nature or type whatsoever, up to the date of this Agreement, except

or purported to transfer or assign, to any person, firm, or corporation any claims, demands, obligations, losses, causes of action,
damages, penalties, costs, expenses, attorneys’ fees, liabilities or indemnities herein released. Each of the parties represents
and warrants that neither it nor any assignee has filed any lawsuit against the other.

 

(d)No Limitations
on Releases. The parties to this Agreement waive any and all rights (to the extent permitted by state law, federal law, principles
of common law or any other law) which may have the effect of limiting the releases as set forth in this Section 4. Without
limiting the generality of the foregoing, the parties acknowledge that there is a risk that the damages which they believe they
have suffered or will suffer may turn out to be other than or greater than those now known, suspected, or believed to be true.
In addition, the cost and damages they have incurred or have suffered may be greater than or other than those now known. Facts
on which they have been relying in entering into this Agreement may later turn out to be other than or different from those now
known, suspected or believed to be true. The parties acknowledge that in entering into this Agreement, they have expressed that
they agree to accept the risk of any such possible unknown damages, claims, facts, demands, actions, and causes of action.

are binding, unconditional and final as of the date hereof.

by any party in connection herewith shall survive the execution and delivery of this Agreement and the consummation of the transactions
contemplated hereby.

 

(b)        
Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective
and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal, or unenforceable in any
respect under any applicable law or rule in any jurisdiction, such invalidity, illegality, or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be reformed, construed, and enforced in such jurisdiction
as if such invalid, illegal, or unenforceable provision had never been contained herein.

 

(c)         
Complete Agreement. This Agreement and any other agreements ancillary thereto and executed and delivered on the date hereof
embody the complete agreement and understanding between the parties and supersede and preempt any prior understandings, agreements,
or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

 

(d)        
Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed to be an original and all
of which taken together constitute one and the same agreement. In the event that any signature to this Agreement is delivered by
facsimile transmission or by e-mail delivery of a portable document format (.pdf or similar format) data file, such signature shall
create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force
and effect as if such facsimile or “.pdf” signature page were an original thereof.

 

(e)         
Assignment; Successors and Assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder shall
be assigned, in whole or in part, by any of the parties without the prior written consent of the other parties. Subject to the
preceding sentence, this Agreement shall bind and inure to the benefit of and be enforceable by the Seller and the Company and
their respective successors and permitted assigns. Any purported assignment not permitted under this paragraph shall be null and
void.

 

(f)         
No Third Party Beneficiaries or Other Rights. This Agreement is for the sole benefit of the parties and their successors
and permitted assigns and nothing herein express or implied shall give or shall be construed to confer any legal or equitable rights
or remedies to any person other than the parties to this Agreement and such successors and permitted assigns; provided, however,
that the Seller Releasees and the Company Releasees shall be third party beneficiaries with respect to Sections 3(i) and 4 hereof.

 

(g)        
Governing Law; Jurisdiction. The Agreement and all disputes arising out of or related to this agreement (whether in contract,
tort or otherwise) will be governed by and construed in accordance with the laws of the State of Delaware. EACH OF THE PARTIES
TO THIS AGREEMENT IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS
AGREEMENT. Each of the parties (i) irrevocably submits to the personal jurisdiction of any state or federal court sitting
in Wilmington, Delaware, as well as to the jurisdiction of all courts to which an appeal may be taken from such courts, in any
suit, action or proceeding relating to or arising out of, under or in connection with this Agreement, (ii) agrees that all
claims in respect of such suit, action or proceeding, whether arising under contract, tort or otherwise, shall be brought, heard
and determined exclusively in the Delaware Court of Chancery (provided that, in the event that subject matter jurisdiction is unavailable
in that court, then all such claims shall be brought, heard and determined exclusively in any other state or federal court sitting
in Wilmington, Delaware), (iii) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or
other request for leave from such court, and (iv) agrees not to bring any action or proceeding relating to or arising out
of, under or in connection with this Agreement or the Company’s business or affairs in any other court, tribunal, forum or
proceeding. Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding brought
in accordance with this paragraph. Each of the parties agrees that service of any process, summons, notice or document by U.S.
registered mail to its address set forth herein shall be effective service of process for any action, suit or proceeding brought
against it in accordance with this paragraph, provided that nothing in the foregoing sentence shall affect the right of any party
to serve legal process in any other manner permitted by law.

 

     

     

    

 

(h)        
Representation by Counsel. Each party hereto acknowledges to the other that it has been represented by independent legal
counsel of its own choice throughout all of the negotiations that preceded the execution of this Agreement. Each party further
acknowledges that it and its counsel have had adequate opportunity to make whatever investigation or inquiry they may deem necessary
or desirable in connection with the subject matter of this Agreement prior to the execution hereof.

 

(i)          
Mutuality of Drafting. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event
an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as jointly drafted by the parties,
and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision
of the Agreement.

 

(j)          
Construction. For purposes of this Agreement, whenever the context requires: the singular number shall include the plural,
and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine
and neuter genders; and the neuter gender shall include the masculine and feminine genders.

 

(k)        
Remedies.  The parties hereto agree and acknowledge that money damages will not be an adequate remedy for any breach
of the provisions of this Agreement, that any breach of the provisions of this Agreement shall cause the other parties irreparable
harm, and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting
any bond or deposit) for specific performance or other injunctive relief in order to enforce, or prevent any violations of, the
provisions of this Agreement.

 

(l)          
Amendment and Waiver. The provisions of this Agreement may be amended, modified or waived only with the prior written consent
of the Seller and the Company. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver
of any other provisions of this Agreement, nor shall any waiver constitute a continuing waiver. Moreover, no failure by any party
to insist upon strict performance of any of the provisions of this Agreement or to exercise any right or remedy arising out of
a breach thereof shall constitute a waiver of any other provisions or any other breaches of this Agreement.

 

     

     

    

 

(m)      
Further Assurances. Each of the Company and the Seller shall execute and deliver such additional documents and instruments
and shall take such further action as may be necessary or appropriate to effectuate fully the provisions of this Agreement.

Agreement provides that, prior to the Distribution Date, the Company and the Rights Agent shall, if the Company so directs, supplement or amend any provision of the First Restated Rights Agreement without the approval of any holders of shares of
Common Stock upon 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 Section 27 of the First Restated Rights Agreement, provided that
the First Restated Rights Agreement may not be amended at a time when the Rights (as defined in the First Restated Rights Agreement) are not redeemable; 

WHEREAS, no Distribution Date has occurred prior to the adoption of the amendments to the First Restated Rights Agreement set forth in this Agreement, and the

compliance with the terms of Section 27 of the First Restated Rights Agreement. 
 NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree to amend and restate the First Restated Rights Agreement to read in its entirety 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

the Company, or any Person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan, (iv) any Person who becomes the Beneficial Owner of 15% or more of the shares of Common Stock then
outstanding as a result of a reduction in the number of shares of Common Stock outstanding due to the repurchase of shares of Common Stock by the Company (or any Subsidiary of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company, or any Person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan) unless and until such Person, after becoming aware that such Person has become the Beneficial Owner
of 15% or more of the then outstanding shares of Common Stock, acquires Beneficial Ownership of any one 

  
 2 

 
or more additional shares of Common Stock, (v) any Person who has reported or is required to report Beneficial Ownership of 15% or more of the shares of Common Stock then outstanding
(x) on Schedule 13G under the Exchange Act (or any comparable or successor report) or (y) on Schedule 13D under the Exchange Act (or any comparable or successor report), which Schedule 13D does not state any intention to or
reserve the right to control or influence the management or policies of the Company or engage in any of the actions specified in Item 4 of such schedule (other than the disposition of the Common Stock), and, in either case, within ten
(10) Business Days of being requested by the Company to advise it regarding the same, certifies to the Company that such Person acquired shares of Common Stock in excess of 14.99% or more of the shares of Common Stock then outstanding
inadvertently or without knowledge of the terms of the Rights and who or which, together with all Affiliates and Associates, thereafter reduces such Person’s, together with its Affiliates’ and Associates’, Beneficial Ownership to less
than 15% of the shares of Common Stock then outstanding; provided, however, that if the Person requested to so certify fails to do so within ten (10) Business Days of being requested by the Company or breaches or
violates such certification, then such Person shall become an Acquiring Person immediately after such ten (10) Business Day period or such breach or violation, or (vi) an Exempt Person, but only for so long as such Exempt Person,
together with such Person’s Affiliates and Associates, does not become the Beneficial Owner of any one or more additional shares of Common Stock (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding
Common Stock or pursuant to a split or subdivision of the outstanding Common Stock) while such Person is an Exempt Person. Notwithstanding the foregoing, no Person shall become an “Acquiring Person” solely as a result of any unilateral
grant of any security by the Company or through the exercise of any options, warrants, rights or similar interests (including restricted stock) granted by the Company to its directors, officers and employees.

exercisable immediately or only after the passage of time or upon the satisfaction of one or more conditions (whether or not within the control of such Person), compliance with regulatory requirements or otherwise) pursuant to any agreement,
arrangement or understanding (whether or not in writing) or upon the exercise of conversion rights, exchange rights, other rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the
“Beneficial Owner” of, or to “beneficially own,” (A) securities tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered securities are
accepted for purchase or exchange, (B) securities issuable upon exercise of Rights at any time prior to the occurrence of a Triggering Event, or (C) securities issuable upon exercise of Rights from and after the occurrence of a Triggering
Event which Rights were acquired by such Person or any of such Person’s Affiliates or Associates prior to the Distribution Date or pursuant to Section 3(a) or Section 22 hereof (the “Original Rights”) or pursuant to
Section 11(a)(i) hereof in connection with an adjustment made with respect to any Original Rights; 
 (ii) that such Person or any of such
Person’s Affiliates or Associates, directly or indirectly, has the right to vote or dispose of or has “beneficial ownership” of (as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Exchange Act),
including pursuant to any agreement, arrangement or understanding, whether or not in writing; provided, however, that a Person shall not be deemed the “Beneficial Owner” of, or to “beneficially own,” any security
under this subparagraph (ii) as a result of an agreement, arrangement or understanding to vote such security if such agreement, arrangement or understanding: (A) arises solely from a revocable proxy given in response to a public proxy
or consent solicitation made pursuant to, and in accordance with, the applicable provisions of the General Rules and Regulations under the Exchange Act, and (B) is not reportable by such Person on Schedule 13D under the Exchange Act (or
any comparable or successor report); 

  
 3 

 (iii) that are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate
thereof) with which such Person (or any of such 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 the proviso to subparagraph (ii) of this paragraph (f)) or disposing of any voting securities of the Company; or 
 (iv) that
are the subject of a derivative transaction entered into by such Person or any of such Person’s Affiliates or Associates, including, for these purposes, any derivative security acquired by such Person or any of such Person’s Affiliates or
Associates, that gives such Person or any of such Person’s Affiliates or Associates the economic equivalent of ownership of an amount of such securities due to the fact that the value of the derivative is explicitly determined by reference to
the price or value of such securities, or which provides such Person or any of such Person’s Affiliates or Associates an opportunity, directly or indirectly, to profit, or to share in any profit, derived from any change in the value of such
securities, in any case without regard to whether (a) such derivative conveys any voting rights in such securities to such Person or any of such Person’s Affiliates or Associates, (b) the derivative is required to be, or capable of
being, settled through delivery of such securities, or (c) such Person or any of such Person’s Affiliates or Associates may have entered into other transactions that hedge the economic effect of such derivative. In determining the number
of shares of Common Stock “beneficially owned” by virtue of the operation of this Section 1(f)(iv), the subject Person shall be deemed to “beneficially own” (without duplication) the notional or other number of shares of
Common Stock specified in the documentation evidencing the derivative position as being subject to be acquired upon the exercise or settlement of the applicable right or as the basis upon which the value or settlement amount of such right, or the
opportunity of the holder of such right 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 such documentation or otherwise), as determined by the
Board in good faith to be the number of shares of Common Stock to which the derivative position relates; 
 provided, however, that nothing in
this paragraph (f) shall cause a Person engaged in business as an underwriter of securities to be the “Beneficial Owner” of, or to “beneficially own,” any securities acquired through such Person’s participation in
good faith in a firm commitment underwriting until the expiration of forty days (40) after the date of such acquisition, and then only if such securities continue to be owned by such Person at such expiration of forty (40) days.

ten (10) days’ prior written notice to the Rights Agent. The Rights Agent shall have no duty to supervise, and in no event be liable for, the acts or omissions of any such co-rights agent. In the event the Company appoints one or more

Section 3. Issuance of Rights Certificates. 
 (a)
Until the earlier of (i) the close of business on the tenth Business Day after the Stock Acquisition Date, or (ii) the close of business on the tenth Business Day (or such later date as the Board shall determine) 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(a) of the General Rules and Regulations under the Exchange Act, if upon consummation thereof, such Person would become an
Acquiring Person, in either instance other than pursuant to a Qualified Offer (the earlier of (i) and (ii) being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced (subject to the provisions of
paragraphs (b) and (c) of this Section 3) by the certificates for the Common Stock registered in the names of the holders of the Common Stock (which certificates for Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates (or, for shares participating in the direct registration system, by notations in the respective book entry accounts for the Common Stock), 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 Company will prepare and execute, the Rights Agent will countersign, and the Rights Agent will, if
requested and provided with all the necessary information, 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 

  
 6 

 
each share of Common Stock so held, subject to adjustment as provided herein. To the extent that a Triggering Event under Section 11(a)(ii) hereof has also occurred, the Company may
implement such procedures, as it deems appropriate in its sole discretion, to minimize the possibility that Rights are received by Persons whose Rights would be null and void under Section 7(e) hereof. In the event that an adjustment in
the number of Rights per share of Common Stock has been made pursuant to Section 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, and the Right Certificates and the Rights will be transferable separately from the transfer of shares of Common Stock. The Company shall promptly notify the Rights Agent in writing upon occurrence of a Distribution Date.
Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that a Distribution Date has not occurred. 

(b) The Company will make available a copy of the Summary of Rights, in substantially the form attached hereto as Exhibit C (the “Summary of
Rights”) to any holder of Rights who may so request from time to time prior to the Expiration Date. With respect to certificates for the Common Stock outstanding as of the Record Date, or issued subsequent to the Record Date, unless and until
the Distribution Date shall occur, the Rights will be evidenced by the certificates for the Common Stock (or, in the case of shares reflected on the direct registration system, the notations in the book-entry account system of the transfer agent for
the Common Stock), and the registered holders of the Common Stock shall also be the registered holders of the associated Rights. Until the earlier of the Distribution Date or the Expiration Date, the transfer of any 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. Notwithstanding anything to the contrary set forth in this Agreement, upon the effectiveness of a redemption pursuant to
Section 23 hereof or an exchange pursuant to Section 24 hereof, the Company shall not thereafter issue any additional Rights and, for the avoidance of doubt, no Rights shall be attached to or shall be issued with any shares of Common Stock
(including any shares of Common Stock issued pursuant to an exchange) at any time thereafter. 
 (c) Rights shall be issued in respect of all shares of
Common Stock that are issued (whether originally issued or delivered from the Company’s treasury) after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date or, in certain circumstances provided in
Section 22 hereof, after the Distribution Date. Certificates representing such shares of Common Stock shall also be deemed to be certificates for Rights, and shall bear a legend in substantially the following form if such certificates are
issued after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date: 
 THIS CERTIFICATE ALSO EVIDENCES AND
ENTITLES THE HOLDER HEREOF TO CERTAIN RIGHTS AS SET FORTH IN THE RIGHTS AGREEMENT BETWEEN SORRENTO THERAPEUTICS, INC. (THE “COMPANY”) AND THE RIGHTS AGENT THEREUNDER (THE “RIGHTS AGENT”) DATED AS OF NOVEMBER 7, 2013, AS
ORIGINALLY EXECUTED AND AS IT MAY BE AMENDED OR RESTATED 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. 

  
 7 

 With respect to such certificates containing the foregoing legend, until the earlier of (i) the Distribution
Date or (ii) the Expiration Date, the Rights associated with the Common Stock represented by such certificates shall be evidenced by such certificates alone and registered holders of Common Stock shall also be the registered holders of the
associated Rights, and the transfer of any of such certificates shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificates. Similarly, during such time periods, transfers of shares
participating in the direct registration system shall also be deemed to be transfers of the associated Rights. In the case of any shares participating in the direct registration system, the Company shall cause the transfer agent for the Common Stock
to include on each direct registration account statement with respect thereto issued prior to the Distribution Date a notation to the effect that the Company will mail to the stockholder a copy of the Agreement, as in effect on the date of mailing,
without charge, promptly after receipt of a written request therefor and that the recipient of the statement, as a holder of shares of Common Stock, may have certain rights thereunder. In the event that shares of the Common Stock are not represented
by certificates, references in this Agreement to certificates shall be deemed to refer to the notations in the book entry accounts reflecting ownership of such shares. 

Section 4. Form of Rights Certificates. 
 (a) The Rights
Certificates (and the forms of election to purchase and of assignment to be printed on the reverse thereof) shall each be substantially in the form set forth in Exhibit B hereto and may have such changes or marks of identification or
designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate (but which do not affect the rights, duties, responsibilities and liabilities of the Rights Agent) 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 applicable rule or regulation of any stock exchange on which the Rights may from time to time be
listed, or to conform to customary usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated as of the Record Date and on their face 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. 
 (b)
Any Rights Certificate issued pursuant to Section 3(a), Section 11(i) or Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person,
(ii) a transferee of an Acquiring Person (or of any Associate or Affiliate of an Acquiring Person) 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 such 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) which has as a primary purpose or effect the avoidance of Section 7(e) hereof, and any Rights Certificate issued pursuant to Section 6 or
Section 11 hereof upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain (if the Company and the Rights Agent have knowledge that such Person is an Acquiring Person or an
Associate or Affiliate thereof or transferee of such Persons or a nominee of any of the foregoing and to the extent feasible) a legend in substantially the following form: 

The Rights represented by this Rights Certificate are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or
Associate of an Acquiring Person (as such terms are defined in the Amended and Restated Rights Agreement between Sorrento Therapeutics, Inc. and Philadelphia Stock Transfer, Inc., as rights agent, dated as of December 21, 2015 (the “Rights
Agreement”)). Accordingly, this Rights Certificate and the Rights represented hereby may become null and void in the circumstances specified in Section 7(e) of the Rights Agreement. 

The Company shall instruct the Rights Agent in writing of the Rights which should be so legended. The Company shall give written notice to the Rights Agent
promptly after the Company becomes aware of the existence and identity of any Acquiring Person or any Associate or Affiliate thereof. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that
no Person has become an Acquiring Person or an Affiliate or an Associate of an Acquiring Person. 

  
 8 

 Section 5. Countersignature and Registration. 

(a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President or any Vice
President, either manually or by facsimile signature, and shall have affixed thereto the Company’s seal or a facsimile thereof which shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile
signature. The Rights Certificates shall be countersigned by the Rights Agent, either manually or by facsimile signature, and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall have signed or
attested 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 or attested such Rights Certificates had not ceased to be such officer of the Company; and any Rights Certificates may be signed or attested
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 or attest such Rights Certificate, although at the date of the execution of this Agreement
any such person was not such an officer. 
 (b) Following the Distribution Date, receipt by the Rights Agent of written notice to that effect and all other
relevant information referred to in Section 3(a) to this Agreement, the Rights Agent will keep, or cause to be kept, at its office or offices designated for such purposes, books for registration and transfer of the Rights Certificates
issued hereunder. Such books shall show the names and addresses of the respective holders of the Rights Certificates, the number of Rights evidenced on its face by each of the Rights Certificates and the date of each of the Rights Certificates. 

Section 6. Transfer, Split Up, Combination and Exchange of Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. 

(a) Subject to the provisions of Section 4(b), Section 7(e) 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 may 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 entitles 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 at
the office or offices of the Rights Agent designated for such purpose. Notwithstanding anything in this Agreement to the contrary, 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 thereof shall have properly completed and duly executed the certificate contained in the form of assignment on the reverse side of such Rights Certificate, 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 or the Rights Agent shall reasonably request. Thereupon the Rights Agent shall, subject to
Section 4(b), Section 7(e), Section 14 hereof and Section 24 hereof, countersign (by manual or facsimile signature) and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so
requested. The Company or the Rights Agent may require from the holders of the Rights Certificates payment of a sum sufficient to cover any tax or charge that may be imposed in connection with any transfer, split up, combination or exchange of
Rights Certificates. If and to the extent the Company does require payment of any such taxes or charges, the Company shall give the Rights Agent prompt written notice thereof and the Rights Agent shall not deliver any Right Certificate unless and
until it is satisfied that all such payments have been made, and the Rights Agent shall forward any such sum collected by it to the Company or to such Persons as the Company shall specify by written notice. The Rights Agent shall have no duty or
obligation to take any action under any section of this Agreement related to the issuance or delivery of Rights Certificates unless and until the Rights Agent is satisfied that all such taxes and/or charges have been paid. 

(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 such additional evidence of the identity of the Beneficial Owner 

  
 9 

 
(or former Beneficial Owner) or Affiliates or Associates thereof as the Company or the Rights Agent shall reasonably request, 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 holder 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, at any time after the Distribution Date the registered holder of any Rights Certificate may exercise the Rights
evidenced thereby (except as otherwise provided herein including the restrictions on exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a) hereof) in whole or in part upon surrender of the Rights
Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed and properly completed, to the Rights Agent at the office or offices of the Rights Agent designated for such purpose, together with
payment of the aggregate Purchase Price with respect to the total number of one one-thousandths of a share of Preferred Stock (or other securities, cash or other assets, as the case may be) as to which such surrendered Rights are then exercisable,
at or prior to the earliest of (i) 5:00 P.M., New York City time, on November 7, 2018 or such later date as may be established by the Board prior to the expiration of the Rights (such date, as it may be extended by the Board, the
“Final Expiration Date”), or (ii) the time at which the Rights are redeemed as provided in Section 23 hereof, or (iii) the time at which the Rights may be exchanged as provided in Section 24 hereof, or (iv) the
time at which all of the Rights expire pursuant to Section 13(d) hereof (the earliest of (i), (ii), (iii) and (iv) 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 initially shall be $40.00, shall be
subject to adjustment from time to time as provided in Section 11 and Section 13(a) hereof and shall be payable 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 and properly
completed, 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 as set
forth below and an amount equal to any applicable tax or charge required to be paid by the holder of such Rights Certificate in cash, or by certified bank check, money order, cashier’s check or bank draft payable to the order of the Company,
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 irrevocably authorizes its transfer agent to comply with all 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 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 will direct the depositary agent to
comply with such request, (ii) when necessary to comply with this Agreement, requisition from the Company the amount of cash, if any, to be paid in lieu of the issuance 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) when necessary to comply with this Agreement, 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) shall be made in cash or by certified bank check, money order, cashier’s check or bank draft 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 will make all arrangements necessary so that such other securities, cash and/or other property are
available for distribution by the Rights Agent, if and when necessary to comply with this Agreement. The Company reserves the right to require prior to the occurrence of a Triggering Event that, upon any exercise of Rights, a number of Rights be
exercised so that only whole shares of Preferred Stock would be issued. 

  
 10 

 (d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced
thereby, a new Rights Certificate evidencing 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 Associate
or Affiliate of an Acquiring Person) who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or of any Associate or Affiliate of an Acquiring Person) 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 which has as a primary purpose or effect the 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, or any
Rights Certificate which formerly evidenced such Rights. The Company shall use all reasonable efforts to insure that the provisions of this Section 7(e) and Section 4(b) hereof are complied with, but neither the Company nor the
Rights Agent shall have any liability to any holder of Rights Certificates or any other Person as a result of the Company’s failure to make any determinations with respect to an Acquiring Person or any of such Acquiring Person’s
Affiliates, Associates or transferees hereunder. The Company shall give the Rights Agent written notice of the identity of any such Acquiring Person, Associate or Affiliate, or the nominee of any of the foregoing, and the Rights Agent may rely on
such notice in carrying out its duties under this Agreement and shall be deemed not to have any knowledge of the identity of any such Acquiring Person, Associate or Affiliate, or the nominee of any of the foregoing unless and until it shall have
received such notice. 
 (f) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered holder shall have (i) properly completed and duly executed the certificate
contained in the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise, and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner)
or Affiliates or Associates thereof as the Company or the Rights Agent shall reasonably request. 
 Section 8. Cancellation and Destruction of
Rights Certificates. 
 All Rights Certificates surrendered for the purpose of exercise, transfer, split up, combination, redemption 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, or cause to be destroyed, 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) The Company covenants and agrees that it will cause to be reserved and kept 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 or out of its authorized and issued shares held in its treasury), the number of shares of
Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) that, as provided in this Agreement including Section 11(a)(iii) hereof, will be sufficient to permit the exercise in full of all
outstanding Rights. 

  
 11 

 (b) So long as the shares of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock
and/or other securities) issuable and deliverable upon the exercise of the Rights may be listed on any national securities exchange, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable (but only
to the extent that it is reasonably likely that the Rights will be exercised), all shares reserved for such issuance to be listed on such exchange 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 pursuant to this Agreement (including in accordance with Section 11(a)(iii) hereof), or as soon as
is required by law following the Distribution Date, 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, and (iii) cause such registration statement to 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. 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. Upon any suspension referred to in this paragraph, the Company shall issue a public announcement stating,
and promptly notify the Rights Agent in writing, that the exercisability of the Rights has been temporarily suspended, as well as a public announcement and prompt written notification to the Rights Agent at such time as the suspension has been
rescinded. In addition, if the Company shall determine that a registration statement is required following the Distribution Date, the Company may temporarily suspend the exercisability of the Rights until such time as a registration statement has
been declared effective. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction if the requisite qualification in such jurisdiction shall not have been obtained, the exercise thereof
shall not be permitted under applicable law, or a registration statement in respect thereof shall not have been declared effective. 
 (d) The Company
covenants and agrees that it will take all such action as may be necessary to ensure that all one one-thousandths of a share of Preferred Stock (and, following the occurrence of a Triggering Event, Common Stock and/or other securities) delivered
upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable. 

(e) The Company further covenants and agrees that it will pay when due and payable any and all taxes and charges which 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 to pay any tax or charge which 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 Certificates evidencing Rights surrendered for exercise or 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 Certificates at the time of surrender) or until it has been established to the Company’s and the Rights Agent’s satisfaction that no such tax or charge 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 duly surrendered and payment of the Purchase Price (and all applicable taxes and
charges) 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 

  
 12 

 
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 shall not be entitled to any rights of a stockholder of the Company with respect to shares for which the Rights shall be exercisable, including 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 or split the outstanding shares of Preferred Stock, (C) combine or
consolidate the outstanding shares of Preferred Stock into a smaller number of shares, through a reverse stock split or otherwise, 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 or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price in
effect at the time of the record date for such dividend or of the effective date of such subdivision, split, combination, consolidation 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, such holder would have owned upon such exercise and
been entitled to receive by virtue of such dividend, subdivision, split, combination, consolidation or reclassification. If an event occurs which 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 hereof, in the event that any Person shall, at any time after the Rights Dividend Declaration Date, become an Acquiring
Person, unless the event causing such Person to become an Acquiring Person is a transaction set forth in Section 13(a) hereof, or is an acquisition of shares of Common Stock pursuant to a tender offer or an exchange offer for all
outstanding shares of Common Stock at a price and on terms determined by at least a majority of the members of the Board who are not officers of the Company and who are not representatives, nominees, Affiliates or Associates of an Acquiring Person,
after receiving advice from one or more investment banking firms, to be (a) at a price which is fair to stockholders and not inadequate (taking into account all factors which such members of the Board deem relevant, including, without
limitation, prices which could reasonably be achieved if the Company or its assets were sold on an orderly basis designed to realize maximum value) and (b) otherwise in the best interests of the Company and its stockholders (a “Qualified
Offer”), then, promptly following the 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 of the Company as shall equal 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 fifty percent
(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”). The Company shall notify the
Rights Agent when this Section 11(a)(ii) applies. 
 (iii) In the event that the number of shares of Common Stock which is authorized by the
Company’s restated certificate of incorporation, as amended, but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights, is not sufficient to permit the exercise in full of the Rights in accordance with the
foregoing subparagraph (ii) of this Section 11(a), the Company shall (A) determine the value of the Adjustment Shares issuable upon the exercise of a Right (the “Current Value”), and (B) with respect to each Right
(subject to 

  
 13 

 
Section 7(e) hereof), make adequate provision to substitute for the Adjustment Shares, upon the exercise of a Right and payment of the applicable Purchase Price, (1) cash,
(2) a reduction in the Purchase Price, (3) Common Stock or other equity securities of the Company (including shares, or units of shares, of preferred stock, such as the Preferred Stock, which the Board has deemed to have essentially the
same value or economic rights as shares of Common Stock (such shares of preferred stock being referred to as “Common Stock Equivalents”)), (4) debt securities of the Company, (5) other assets, or (6) any combination of the
foregoing, having an aggregate value equal to the Current Value (less the amount of any reduction in the Purchase Price), 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, whose determination shall be described in a statement filed with the Rights Agent that shall be binding on the Rights Agent and holders of Rights; provided, however, that if the Company shall not have made
adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the later of (x) the first occurrence of a Section 11(a)(ii) Event and (y) the date on which the Company’s
right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the “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. For purposes
of the preceding sentence, the term “Spread” shall mean the excess of (i) the Current Value over (ii) the Purchase Price. If the Board determines 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 (with prompt written notice of such extension to the Rights Agent), but not more than
ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares (such thirty (30) day period, as it may be extended, is
herein called the “Substitution Period”). To the extent that the Company determines that action should be taken pursuant to the first and/or third sentences of this Section 11(a)(iii), the Company (1) shall provide, subject to
Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights, and (2) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek such stockholder approval for
such 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, and promptly notify the Rights Agent in writing, that the exercisability of the Rights has been temporarily suspended, as well as a public announcement and prompt written notification to the Rights Agent at such time as the
suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of each Adjustment Share shall be the Current Market Price per share of Common Stock on the Section 11(a)(ii) Trigger Date and the per share or per
unit value of any Common Stock Equivalent shall be deemed to equal the Current Market Price per share of 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 shares of Preferred Stock entitling them to subscribe for or purchase (for a period expiring within forty-five (45) calendar days after such
record date) shares of 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). 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 that shall be binding on the Rights Agent and holders of Rights. Shares of Preferred Stock owned by or held for the account of the Company shall not be deemed
outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights or warrants are not so issued, the Purchase Price shall be adjusted to be the
Purchase Price which would then be in effect if such record date had not been fixed. 

  
 14 

 (c) In case the Company shall fix a record date for a distribution to all holders of shares of Preferred Stock
(including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), 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 evidences of indebtedness, or of 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 and binding on the Rights Agent, the holders of the Rights and all other Persons) 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. 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 immediately prior to but not including 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 but not including 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, consolidation, reverse stock split or reclassification of such Common Stock, and the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination, consolidation,
reverse stock split or reclassification shall not have occurred prior to the commencement of the requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth above, then, and in each such case, the Current
Market Price shall be properly adjusted to take into account ex dividend trading. 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 NASDAQ Stock Market LLC (“NASDAQ”) or, if the shares of Common Stock
are not listed or admitted to trading on the NASDAQ, as reported in the principal consolidated transaction reporting system with respect to securities listed 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 low asked prices in the
over-the-counter market, as reported by NASDAQ, or such other 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. 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 that shall be binding on the Rights Agent and holders of Rights. The term “Trading Day” shall mean a day on which the principal 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, the 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. 

  
 15 

 (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, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. 

(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 thousandth of a share of Common Stock or other share or one millionth of a share of Preferred Stock, as the case may be.
Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three (3) 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 shares of capital stock other than Preferred Stock, thereafter the number of such other shares so receivable upon exercise of any Right
and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in Sections 11(a), (b), (c), (e), (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 shares. 

(g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the
adjusted Purchase Price, the number of 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) hereof, upon each adjustment of the Purchase Price as a result
of the calculations made in Sections 11(b) and (c) hereof, each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one
one-thousandths of a share of Preferred Stock (calculated to the nearest one-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 ten-thousandth)
obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election
to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made, and shall promptly give the Rights Agent a copy of such announcement. 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 

  
 16 

 
promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14 hereof, the additional
Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall
be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Rights Certificates on the record date
specified in the public announcement. 
 (j) Irrespective of any adjustment or change in the Purchase Price or the number of 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-thousandth 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 stated 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 fully paid and nonassessable such number of one one-thousandths of a share of 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 (with prompt written notice thereof to the Rights Agent) 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 their good faith judgment 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 which complies with Section 11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), or
(iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of related transactions, assets, cash flow or earning power aggregating more than 50% of the assets, cash flow or earning power of the
Company and its Subsidiaries (taken as a whole) to any 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 or sale there are any rights, warrants or other instruments or securities outstanding or agreements in effect which 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 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 and Associates. 
 (o)
The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted by Section 23, Section 24 or Section 27 hereof, take (or permit any Subsidiary to take) any action if 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. 

  
 17 

 (p) Anything in this Agreement to the contrary notwithstanding, in the event that the Company shall at any time
after the Rights Dividend Declaration Date and prior to the Distribution Date (i) declare a dividend on the outstanding shares of Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding shares of Common Stock, or
(iii) combine the outstanding shares of Common Stock into a smaller number of shares, the number of Rights associated with each share of Common Stock then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall
be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result obtained by multiplying the number of Rights associated with each share of Common Stock
immediately prior to such event by a fraction the numerator which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of
Common Stock outstanding immediately following the occurrence of such event. 
 Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made or any event affecting the Rights or their exercisability (including without limitation an event which causes the Rights to become null and void) occurs as provided in Section 11 and Section 13
hereof, the Company shall (a) promptly prepare a certificate setting forth such adjustment or describing such event and a brief, reasonably detailed statement of the facts and computations accounting for such adjustment or event,
(b) promptly file with the Rights Agent, and with each transfer agent for the Preferred Stock and the Common Stock, a copy of such certificate and (c) if a Distribution Date has occurred, mail a brief summary thereof to each holder of a
Rights Certificate (or, if prior to the Distribution Date, to each holder of a certificate representing shares of Common Stock) in accordance with Section 25 hereof. The Rights Agent shall be fully protected in relying on any such certificate
and on any adjustment or statement contained therein and shall have no duty or liability with respect to, and shall not be deemed to have knowledge of, any such adjustment or any such event unless and until it shall have received such certificate.

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

(a) In the event that, following the Stock Acquisition Date, directly or indirectly, (x) the Company shall consolidate with, or merge with and into, any
other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), and the Company shall not be the continuing or surviving corporation of such consolidation or merger, (y) any Person (other
than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof) shall consolidate with, or merge with or into, the Company, and the Company shall be the continuing or surviving corporation of such consolidation or
merger and, in connection with such consolidation or merger, all or part of the outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of 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, cash flow or earning power aggregating more than fifty percent
(50%) of the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons (other than the Company or any Subsidiary of the Company in one or more transactions each of which complies with
Section 11(o) hereof), then, and in each such case (except as may be contemplated by Section 13(d) hereof), proper provision shall be made so that: (i) 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 tradeable
shares of Common Stock of the Principal Party, not 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 of a Section 11(a)(ii) Event), 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)(i) 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 

  
 18 

 
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 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 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: 
 (i) in the case of
any transaction described in clause (x) or (y) of the first sentence of Section 13(a) hereof, the Person that is the issuer of any securities into which shares of Common Stock of the Company are converted in such merger or
consolidation, and if no securities are so issued, the Person that is the other party to such merger or consolidation; and 
 (ii) in the case of any
transaction described in clause (z) of the first sentence of Section 13(a) hereof, the Person that is the party receiving the greatest portion of the assets, cash flow 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; and (2) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Stock 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. 
 (c)
The Company shall not consummate any such consolidation, merger, 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 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) take all such other action as may be necessary to enable the Principal Party to issue the
securities purchasable upon exercise of the Rights, including the registration or qualification of such securities under all requisite securities laws of jurisdictions of the various states and the listing of such securities on such exchanges and
trading markets as may be necessary or appropriate; and 
 (iii) deliver to holders of the Rights historical financial statements for the Principal Party
and each of its Affiliates, which comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act. 

The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other transfers. In the event that a
Section 13 Event shall occur 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). 

(d) Notwithstanding anything in this Agreement to the contrary, Section 13 shall not be applicable to a transaction described in
subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is consummated with a Person or Persons who acquired shares of Common Stock pursuant to a tender offer or exchange offer for all outstanding shares of
Common Stock which is a Qualified Offer as such term is defined in Section 11(a)(ii) hereof (or a wholly owned subsidiary of any such Person or Persons), (ii) the price per share of Common Stock offered in such transaction is not less
than the price per share of Common Stock paid to all holders of shares of Common Stock whose shares were purchased pursuant to such tender offer or exchange offer and (iii) the form of consideration being offered to the remaining holders of
shares of Common Stock pursuant to such transaction is the same as the form of consideration paid pursuant to such tender offer or exchange offer. Upon consummation of any such transaction contemplated by this Section 13(d), all Rights
hereunder shall expire.

 Section 14. Fractional Rights and Fractional Shares. 

(a) The Company shall not be required to issue fractions of Rights, except prior to the Distribution Date as provided in Section 11(p) hereof, or to
distribute Rights Certificates which evidence fractional Rights. In lieu of such fractional Rights, the Company shall pay 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 Trading 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 NASDAQ or, if the Rights are not listed or admitted to
trading on NASDAQ, as reported in the principal consolidated transaction reporting system with respect to securities listed 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 low asked prices in the over the counter market, as reported by NASDAQ or such other 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. 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 the Rights Agent that shall be binding
on the Rights Agent and holders of Rights. 
 (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 which evidence fractional shares of Preferred Stock (other than fractions which are integral multiples of one
one-thousandth of a share of Preferred Stock). In lieu of fractional shares of Preferred Stock that are not integral multiples of one one-thousandth of a share of Preferred Stock, the Company may pay to the registered holders of Rights Certificates
at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of 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) Following the occurrence of a Triggering Event, the Company shall not be required to issue fractions of shares of Common Stock upon
exercise of the Rights or to distribute certificates which evidence fractional shares of Common Stock. In lieu of fractional shares of Common Stock, the Company may pay to the registered holders of Rights Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the current market value of one (1) share of Common Stock. For purposes of this Section 14(c), the current market value of one share of Common Stock shall be
the closing price per share of Common Stock (as determined pursuant to Section 11(d)(i) hereof) on the Trading Day immediately prior to the date of such exercise. 

(d) The holder of a Right by the acceptance of the Rights expressly waives such holder’s right to receive any fractional Rights or any fractional shares
upon exercise of a Right, except as permitted by this Section 14. 
 (e) Whenever a payment for fractional Rights or fractional shares is to be made by
the Rights Agent under any Section of this Agreement, the Company shall (i) promptly prepare and deliver to the Rights Agent a certificate setting forth in reasonable detail the facts related to such payment and the prices and/or formulas
utilized in calculating such payments, and (ii) provide sufficient monies to the Rights Agent in the form of fully collected funds to make such payments. The Rights Agent shall be fully protected in relying upon such a certificate and shall
have no duty with respect to, and shall not be deemed to have knowledge of any payment for fractional Rights or fractional shares under any Section of this Agreement relating to the payment of fractional Rights or fractional shares unless and until
the Rights Agent shall have received such a certificate and sufficient monies. 

  
 20 

 Section 15. Rights of Action. All rights of action in respect of this Agreement, except those rights of
action given to the Rights Agent hereunder, 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 such holder’s own
behalf and for such holder’s own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, such holder’s 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 by the Company of this Agreement and shall be entitled to specific performance of the obligations hereunder and injunctive relief against actual or threatened violations by the Company 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 transferable only in connection with the transfer of shares of Common Stock; 
 (b) after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent if surrendered at the office or offices 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 properly completed and fully executed; 
 (c) subject to Section 6(a) and Section 7(f) hereof, the Company and the Rights
Agent may deem and treat the Person in whose name a Rights Certificate (or, prior to the Distribution Date, the associated Common Stock certificate (or book entry shares in respect of Common Stock)) is registered as the absolute owner thereof and of
the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Rights Certificates or the associated Common Stock certificate (or notices provided to holders of book entry shares of Common Stock) 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 last 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 the inability of the Company or the Rights Agent to perform any of its or their obligations under this Agreement by reason of any preliminary or permanent injunction or other order, judgment, decree or ruling (whether
interlocutory or final) issued by a court of competent jurisdiction or by a governmental, regulatory, self-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 shall use its best efforts to have any such injunction, order, judgment, 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 or
exchange of the Rights represented thereby, nor shall anything contained herein or in any Rights 

  
 21 

 
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 or exchanged 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 preparation, negotiation, delivery, amendment, 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, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense (including, without limitation, the reasonable fees and expenses of counsel), incurred without gross negligence, bad faith or willful
misconduct on the part of the Rights Agent (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction), for any action taken, suffered, or omitted to be taken
by the Rights Agent in connection with the acceptance, administration, exercise and performance of its duties under this Agreement, including, without limitation, the costs and expenses of defending against any claim of liability and appealing any
claim of liability arising therefrom, directly or indirectly. The provisions of this Section 18 and Section 20 below shall survive the termination of this Agreement, the exercise or expiration of the Rights and the resignation, replacement
or removal of the Rights Agent. The costs and expenses incurred in enforcing this right of indemnification shall be paid by the Company. 
 (b) The Rights
Agent shall be authorized to rely conclusively on, and shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted to be taken by it in connection with its acceptance and administration of this
Agreement and in the exercise and performance of its duties hereunder, in reliance upon any Rights Certificate or certificate for Common Stock or, in the case of uncertificated shares, the associated balance indicated in the book-entry account
system of the transfer agent for the 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, in the absence of gross negligence, bad faith or willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction), 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 of this Agreement. The Rights Agent shall not be deemed to
have any knowledge of any event of which it was supposed to receive notice thereof hereunder, and the Rights Agent shall be fully protected and shall incur no liability for failing to take action in connection therewith unless and until it has
received such notice in writing. 
 Section 19. Merger or Consolidation or Change of Name of Rights Agent. 

(a) Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the shareholder services 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; but only if such Person would be eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. The purchase of all or substantially all of the Rights Agent’s assets employed in the performance of transfer agent activities shall be deemed a merger or consolidation for purposes of this Section 19. 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 Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. 

(b) In case at any time the name of the Rights Agent shall be changed and at such time any of the Rights Certificates shall have been countersigned but not
delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may
countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. 

  
 22 

 Section 20. Duties of Rights Agent. The Rights Agent undertakes to perform the duties and obligations
expressly imposed by this Agreement (and no implied duties or obligations) 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) Before the Rights Agent acts or refrains from acting, the Rights Agent may consult with legal counsel selected by it (who may be legal counsel for the
Company or an employee of the Rights Agent), and the opinion or advice of such counsel shall be full and complete authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken,
suffered or omitted to be taken by it in the absence of gross negligence, bad faith and willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent
jurisdiction) and in accordance with such opinion or advice. 
 (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, suffering or omitting
to take 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 Chief
Executive Officer, the Chief Financial Officer, 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
and complete authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted to be taken in the absence of gross negligence, bad faith or willful misconduct
(which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction) by it under the provisions of this Agreement in reliance upon such certificate. 

(c) The Rights Agent shall be liable hereunder to the Company and any other Person only for its own gross negligence, bad faith or willful misconduct (each as
determined by a final, non-appealable judgment of a court of competent jurisdiction). Anything to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, consequential or incidental loss or damage
of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. Any liability of the Rights Agent under this Agreement will be limited to the amount of annual
fees paid by the Company to the Rights Agent. 
 (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 have any liability for or 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 change in the
exercisability of Rights (including Rights becoming null and void pursuant to Section 7(e) hereof) except with respect to the exercise of Rights evidenced by Rights Certificates after actual notice of such change; 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 or change 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 change 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 by the Rights Agent of a certificate furnished pursuant to Section 12 hereof describing such change or adjustment upon which the Rights 

  
 23 

 
Agent may rely); nor shall it be responsible for any determination by the Board of the current market value of the Rights or Preferred Stock or Common Stock pursuant to the provisions of
Section 14 hereof; 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 its duties under this Agreement. 

(g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder and certificates
delivered pursuant to any provision hereof from the Chairman of the Board, the Chief Executive Officer, the Chief Financial Officer, the President, any Vice President, the Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer
of the Company, and is authorized to apply to such officers for advice or instructions in connection with its duties, and such advice and instructions shall be full authorization and protection to the Rights Agent and the Rights Agent shall not be
liable for or in respect of any action taken, suffered, or omitted to be taken by it in accordance with written advice or instructions of any such officer or for any delay in acting while waiting for those instructions. The Rights Agent shall be
fully authorized and protected in relying upon the most recent instructions received by any such officer. 
 (h) The Rights Agent and any member,
stockholder, affiliate, 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 the Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent or any such stockholder, affiliate, director, officer or
employee from acting in any other capacity for the Company or for any other Person. 
 (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 (through its directors, officers and employees) or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss to the Company, to the holders of the Rights or any other Person resulting from any such act, omission, default, neglect or misconduct, absent gross negligence, bad faith
or willful misconduct in the continued employment thereof (each as determined by a final, non-appealable judgment of a court of competent jurisdiction). 

(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 (other than internal costs incurred by the Rights Agent in providing services to the Company in the ordinary course of its business as Rights Agent) or in the exercise of its rights if it reasonably
believes, after consultation with counsel, 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 either not been properly completed or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested
exercise or transfer without first consulting with the Company. 
 (l) The Rights Agent shall not be required to take notice or be deemed to have notice of
any fact, event or determination (including, without limitation, any dates or events defined in this Rights Agreement or the designation of any Person as an Acquiring Person, Affiliate or Associate) under this Rights Agreement unless and until the
Rights Agent shall be specifically notified in writing by the Company of such fact, event or determination. 
 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 known to the Rights Agent, by registered or 

  
 24 

 
certified mail at the expense of the Company, and, if such resignation occurs after the Distribution Date, to the registered holders of the Rights Certificates by first class mail. In the event
the transfer agency relationship in effect between the Company and the Rights Agent terminates, the Rights Agent will be deemed to resign automatically on the effective date of such termination; and any required notice will be sent by the Company.
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, and, if such removal occurs after the Distribution Date, to the holders of the Rights Certificates by first class mail. If the Rights Agent shall resign or be removed or shall otherwise become
incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of 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 the Rights Agent or
any registered holder of any Rights Certificate may apply at the expense of the Company 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 either be (a) a Person organized and doing business under the laws of the United States or any state of the United States, in good standing, which is authorized under such laws to exercise stock transfer or stockholder services
powers 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; and, except as the context herein otherwise requires, such successor Rights Agent shall be deemed to be the “Rights Agent” for all purposes of this Agreement. 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, and, if such appointment occurs after the Distribution Date, mail a notice
thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the
Rights Agent or the appointment of the successor Rights Agent, as the case may be. 
 Section 22. Issuance of New Rights Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by 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. In addition, in connection with the issuance
or sale of shares of Common Stock following the Distribution Date and prior to the redemption, exchange or expiration of the Rights, the Company (a) shall, with respect to shares of Common Stock so issued or sold pursuant to the exercise of
stock options or under any employee benefit plan or arrangement, granted or awarded as of the Distribution Date, or upon the exercise, conversion or exchange of securities hereinafter issued by the Company (except as may otherwise be provided in the
instrument(s) governing such securities), and (b) 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 (i) no such Rights Certificate shall be issued if, and to the extent that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to
the Company or the Person to whom such Rights Certificate would be issued, and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

 Section 23. Redemption and Termination. 
 (a)
The Board may, at its option, at any time prior to the earlier of (i) the close of business on the tenth Business Day following the Stock Acquisition Date, or (ii) the Final Expiration Date, redeem all but not less than all of 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 the “Redemption Price”). Notwithstanding anything contained in this Agreement to the contrary, the Rights shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event until such time
as the Company’s right of redemption hereunder has expired. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on the Current Market Price of the Common Stock at the time of redemption) or any other
form of consideration deemed appropriate by the Board. 
 (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 will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price
for each Right so held. The Company shall promptly give public notice of any such redemption (with prompt written notice thereof to the Rights Agent); provided, however, that the failure to give, or any defect in, such notice shall not affect the
legality or validity of such redemption. 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. 

  
 25 

 Section 24. Exchange. 

(a) The Board may, at its option, at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable
Rights (which shall not include Rights that have become null and void pursuant to the provisions of Section 7(e) hereof) for 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 (i) 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 fifty percent (50%) or more of the Common Stock then outstanding or (ii) the occurrence of an event specified in
Section 13(a) hereof. 
 (b) Immediately upon the action of the Board ordering the exchange of any Rights pursuant to subsection (a) of
this Section 24 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 (with prompt written notice thereof to the Rights Agent); provided, however, that the
failure to give, or any defect in, such notice shall not affect the legality or 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 that is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the
Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights that will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become null
and 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 subsection (a) of this Section 24, the Company may implement such procedures in its sole discretion as it deems appropriate for the purpose of ensuring that the Common Stock (or such other
consideration) issuable upon an exchange pursuant to this Section 24 not be received by holders of Rights that have become null and void pursuant to Section 7(e) hereof. In furtherance thereof, if so directed by the Company, all or a
portion of the shares of Common Stock (or other consideration) potentially issuable to holders of Rights upon an exchange pursuant to this Section 24, who have not verified to the satisfaction of the Company, in its sole discretion, that they
are not Acquiring Persons, may be deposited in a trust established by the Company pending receipt of appropriate verification. 
 (d) In any exchange
pursuant to this Section 24, the Company, at its option, may substitute Preferred Stock (or Equivalent Preferred Stock) for Common Stock exchangeable for Rights, at the initial rate of one one-thousandth of a share of Preferred Stock (or
Equivalent Preferred Stock) for each share of Common Stock, as appropriately adjusted to reflect stock splits, stock dividends and other similar transactions after the date hereof. 

  
 26 

 (e) In the event that there shall not be sufficient shares of Common 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 for issuance upon exchange of
the Rights. 
 (f) 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 Rights 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 (f), 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 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 which 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 fifty percent (50%) of the assets, cash flow 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 the Rights Agent and, to the extent feasible, to each holder of a Rights Certificate in accordance with Section 26 hereof, a notice of such proposed action, which shall specify the
record date for the purposes of such stock dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, 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 but not including 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 but not including 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. 
 (b)
In case any of the events set forth in Section 11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall as soon as practicable thereafter give to the Rights Agent and, to the extent feasible, each holder of a Rights
Certificate, 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 to Common Stock and/or, if appropriate, other securities.

ambiguity, (ii) correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein, (iii) shorten or lengthen any time period hereunder or (iv) change or supplement the

Notwithstanding anything contained in this Agreement to the contrary, the Rights Agent may, but shall not be obligated to, enter into any supplement or amendment that affects the Rights Agent’s own rights, duties and obligations or immunities
under this Agreement and it shall not be bound by any such supplement or amendment not executed by it. 
 Section 28. Successors. All the
covenants and provisions of this Agreement by or for the benefit of the Company or the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder. 

Section 29. Determinations and Actions by the Board, etc. For all purposes of this Agreement, any calculation of the number of shares of Common
Stock or any other class of capital stock outstanding at any particular time, including for purposes of determining the particular percentage of such outstanding shares of Common Stock of which any Person is the Beneficial Owner, shall be made in
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act. 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 the right and power to (i) interpret the provisions of this Agreement and (ii) make all
determinations deemed necessary or advisable for the administration of this Agreement (including a determination to redeem or not redeem the Rights or 

  
 28 

 
to amend the Agreement). All such actions, calculations, interpretations and determinations which are done or made by the Board in good faith, shall be final, conclusive and binding on the
Company, the Rights Agent, the holders of the Rights, as such, and all other Persons. The Rights Agent shall always be entitled to assume that the Board acted in good faith and shall be fully protected and incur no liability in reliance thereon.

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

Section 31. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated; provided,
however, that if such excluded provision shall affect the rights, immunities, duties or obligations of the Rights Agent, the Rights Agent shall be entitled to resign immediately upon written notice to the Company; 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 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 Business Day following the date of such determination by the Board. Without limiting the foregoing, if any provision requiring a specific group of directors to act is held to by any court of competent jurisdiction or other
authority to be invalid, void or unenforceable, such determination shall then be made by the Board in accordance with applicable law and the Company’s restated certificate of incorporation, as amended, and amended and restated bylaws. 

Section 32. Governing Law. This Agreement, each Right and each Rights Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for all purposes shall be governed by and construed in accordance with the laws of such State applicable to contracts made and to be performed entirely within such State; provided, however, that all provisions
regarding the rights, duties and obligations of the Rights Agent shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within the State of New York, without
regard to the principles or rules concerning conflicts of laws which might otherwise require application of the substantive laws of another jurisdiction. 

Section 33. Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. A signature to this Agreement transmitted electronically shall have the same authority, effect and enforceability as an original
signature. 
 Section 34. Descriptive Headings; Interpretation. 

(a) Descriptive headings of the several sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or
construction of any of the provisions hereof. 
 (b) Whenever the words “include,” “includes” or “including” are used in this
Agreement, they shall be deemed to be followed by the words “without limitation.” 
 Section 35. Force Majeure. 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 36. Patriot Act. The Company acknowledges that the Rights Agent is subject to the customer
identification program (“Customer Identification Program”) requirements under the USA PATRIOT Act and its implementing regulations, and that the Rights Agent must obtain, verify and record information that allows the Rights Agent to
identify the Company. Accordingly, prior to accepting an appointment hereunder, the Rights Agent has received information from the Company that will help the Rights Agent to identify the Company, including without limitation the Company’s
physical address, tax identification number, organizational documents, certificate of good standing, license to do business, or any other information that the Company deems necessary and that pending verification of received information the Rights
Agent may request further such information. The Company agrees to provide all reasonably requested information necessary for the Rights Agent to verify the Company’s identity in accordance with the Customer Identification Program requirements.

 Exhibit A 

CERTIFICATION OF DESIGNATION, PREFERENCES AND RIGHTS OF SERIES A JUNIOR 

PARTICIPATING PREFERRED STOCK 
 of

 SORRENTO THERAPEUTICS, INC. 

Pursuant to Section 151 of the 

General Corporation Law of the State of Delaware 

I, Richard Vincent, Chief Financial Officer of Sorrento Therapeutics, Inc., a corporation organized and existing under the General Corporation Law of the
State of Delaware, in accordance with the provisions of Section 103 thereof, DO HEREBY CERTIFY: 
 That pursuant to the authority conferred upon the
Board of Directors by the Restated Certificate of Incorporation of the said Corporation, the said Board of Directors on November 7, 2013 adopted the following resolution creating a series of 1,000,000 shares of Preferred Stock designated
as Series A Junior Participating Preferred Stock: 
 RESOLVED, that pursuant to the authority vested in the Board of Directors of this Corporation in
accordance with the provisions of its Restated Certificate of Incorporation, a series of Preferred Stock of the Corporation be and it hereby is created, and that the designation and amount thereof and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such series, and the qualifications, limitations or restrictions thereof are as follows: 

Section 1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” and
the number of shares constituting such series shall be 1,000,000. 
 Section 2. Dividends and Distributions. 

(A) Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the shares of Series
A Junior Participating Preferred Stock with respect to dividends, the holders of shares of Series A Junior Participating Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available
for the purpose, quarterly dividends payable in cash on the 15th day of March, June, September and December in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the
first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Junior Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00 or
(b) subject to the provision for adjustment hereinafter set forth, 1000 times the aggregate per share amount of all cash dividends, and 1000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock, par value $0.0001 per share, of the Corporation
(the “Common Stock”) since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Junior
Participating Preferred Stock. In the event the Corporation shall at any time after November 7, 2013 (the “Rights Declaration Date”) (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide
the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series A Junior Participating 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. 
 (B) The Corporation shall declare a
dividend or distribution on the Series A Junior Participating Preferred Stock as provided in Paragraph (A) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common
Stock); provided that, in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
$1.00 per share on the Series A Junior Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date. 

(C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Junior Participating Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares of Series A Junior Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends
on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Junior
Participating Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Junior Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Junior Participating Preferred Stock entitled to receive
payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. 

  
 32 

 Section 3. Voting Rights. The holders of shares of Series A Junior Participating Preferred Stock
shall have the following voting rights: 
 (A) Subject to the provision for adjustment hereinafter set forth, each share of Series A Junior Participating
Preferred Stock shall entitle the holder thereof to 1000 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the number of votes per share to
which holders of shares of Series A Junior Participating 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. 

(B) Except as otherwise provided herein or by law, the holders of shares of Series A Junior Participating Preferred Stock and the holders of shares of Common
Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. 
 (C) (i) If at any time dividends on
any Series A Junior Participating Preferred Stock shall be in arrears in an amount equal to six (6) quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a “default
period”) which shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Series A Junior Participating Preferred Stock then
outstanding shall have been declared and paid or set apart for payment. During each default period, all holders of Preferred Stock (including holders of the Series A Junior Participating Preferred Stock) with dividends in arrears in an amount equal
to six (6) quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect two (2) directors. 

(ii) During any default period, such voting right of the holders of Series A Junior Participating Preferred Stock may be exercised initially at a special
meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders, provided that neither such voting right nor the right of the holders of
any other series of Preferred Stock, if any, to increase, in certain cases, the authorized number of directors shall be exercised unless the holders of at least one-third in number of shares of Preferred Stock outstanding shall be present in person
or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Preferred Stock of such voting right. At any meeting at which the holders of Preferred Stock shall exercise such voting right
initially during an existing default period, they shall have the right, voting as a class, to elect directors to fill such vacancies, if any, in the Board of Directors as may then exist up to two (2) directors or, if such right is
exercised at an annual meeting, to elect two (2) directors. If the number which may be so elected at any special meeting does not amount to the required number, the holders of the Preferred Stock shall have the right to make such increase
in the number of directors as shall be necessary to permit the election by 

  
 33 

 
them of the required number. After the holders of the Preferred Stock shall have exercised their right to elect directors in any default period and during the continuance of such period, the
number of directors shall not be increased or decreased except by vote of the holders of Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Junior
Participating Preferred Stock. 
 (iii) Unless the holders of Preferred Stock shall, during an existing default period, have previously exercised their
right to elect directors, the Board of Directors may order, or any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Preferred Stock outstanding, irrespective of series, may
request, the calling of a special meeting of the holders of Preferred Stock, which meeting shall thereupon be called by the Chairman of the Board, the President, an Executive Vice-President, a Vice-President or the Secretary of the Corporation.
Notice of such meeting and of any annual meeting at which holders of Preferred Stock are entitled to vote pursuant to this Paragraph (C)(iii) shall be given to each holder of record of Preferred Stock by mailing a copy of such notice to
him at his last address as the same appears on the books of the Corporation. Such meeting shall be called for a time not earlier than 20 days and not later than 60 days after such order or request or in default of the calling of
such meeting within 60 days after such order or request, such meeting may be called on similar notice by any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of
Preferred Stock outstanding. Notwithstanding the provisions of this Paragraph (C)(iii), no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the
stockholders. 
 (iv) In any default period, the holders of Common Stock, and other classes of stock of the Corporation if applicable, shall continue to be
entitled to elect the whole number of directors until the holders of Preferred Stock shall have exercised their right to elect two (2) directors voting as a class, after the exercise of which right (x) the directors so elected by the
holders of Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the Board of Directors may (except as provided in
Paragraph (C)(ii) of this Section 3) be filled by vote of a majority of the remaining directors theretofore elected by the holders of the class of stock which elected the director whose office shall have become vacant. References in
this Paragraph (C) to directors elected by the holders of a particular class of stock shall include directors elected by such directors to fill vacancies as provided in clause (y) of the foregoing sentence. 

(v) Immediately upon the expiration of a default period, (x) the right of the holders of Preferred Stock as a class to elect directors shall cease,
(y) the term of any directors elected by the holders of Preferred Stock as a class shall terminate, and (z) the number of directors shall be such number as may be provided for in the restated certificate of incorporation of the
Corporation, as amended, or the Corporation’s amended and restated by-laws irrespective of any increase made pursuant to the provisions of Paragraph (C)(ii) of this Section 3 (such number being subject, however, to change
thereafter in any manner provided by law or in the restated certificate of incorporation of the Corporation, as amended, or the Corporation’s amended and restated by-laws). Any vacancies in the Board of Directors effected by the provisions of
clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining directors. 
 (D) Except as set forth herein,
holders of Series A Junior Participating Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any
corporate action. 
 Section 4. Certain Restrictions. 

(A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Junior Participating Preferred Stock as provided in
Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Junior Participating Preferred Stock outstanding shall have been paid in full, the Corporation
shall not: 
 (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of
stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock; 

  
 34 

 (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, except dividends paid ratably on the Series A Junior Participating Preferred Stock and all such parity stock on which
dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; 
 (iii) redeem or
purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, provided that the Corporation may
at any time redeem, purchase or otherwise acquire shares of any such parity 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 Junior
Participating Preferred Stock; or 
 (iv) purchase or otherwise acquire for consideration any shares of Series A Junior Participating Preferred Stock or any
shares of stock ranking on a parity with the Series A Junior Participating Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon
such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable
treatment among the respective series or classes. 
 (B) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire
for consideration any shares of stock of the Corporation unless the Corporation could, under Paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner. 

Section 5. Reacquired Shares. Any shares of Series A Junior Participating Preferred Stock purchased or otherwise acquired by the Corporation in
any manner whatsoever shall be retired and 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 to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein. 

Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock unless, prior thereto, the
holders of shares of Series A Junior Participating Preferred Stock shall have received an amount equal to $1,000 per share of Participating Preferred Stock, Series A, plus an amount equal to accrued and unpaid dividends and distributions
thereon, whether or not declared, to the date of such payment (the “Series A Liquidation Preference”). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the
holders of shares of Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the “Common Adjustment”) equal to the quotient obtained by dividing
(i) the Series A Liquidation Preference by (ii) 1000 (as appropriately adjusted as set forth in subparagraph (C) below to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock)
(such number in clause (ii), the “Adjustment Number”). Following the payment of the full amount of the Series A Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series A Junior Participating
Preferred Stock and Common Stock, respectively, holders of Series A Junior Participating Preferred Stock and holders of shares of Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio
of the Adjustment Number to 1 with respect to such Preferred Stock and Common Stock, on a per share basis, respectively. 
 (B) In the event, however,
that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of preferred stock, if any, which rank on a parity with the Series A Junior
Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets
available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock. 
 (C)
In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine

  
 35 

 
the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such
Adjustment Number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to
such event. 
 Section 7. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination or other
transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in 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 after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock,
(ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of
shares of Series A Junior Participating 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. 
 Section 8. No Redemption. The shares of Series
A Junior Participating Preferred Stock shall not be redeemable. 
 Section 9. Ranking. The Series A Junior Participating Preferred Stock shall
rank junior to all other series of the Corporation’s Preferred Stock as to the payment of dividends and the distribution of assets, unless the terms of any such series shall provide otherwise. 

Section 10. Amendment. At any time when any shares of Series A Junior Participating Preferred Stock are outstanding, neither the Restated
Certificate of Incorporation, as amended, of the Corporation nor this Certificate of Designation shall be amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Junior Participating
Preferred Stock so as to affect them adversely without the affirmative vote of the holders of two-thirds or more of the outstanding shares of Series A Junior Participating Preferred Stock, voting separately as a class. 

Section 11. Fractional Shares. Series A Junior Participating 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 to have the benefit of all other rights of holders of Series A Junior Participating Preferred Stock. 

IN WITNESS WHEREOF, Sorrento Therapeutics, Inc. has caused this Certificate of Designation to be executed in its corporate name this 7th day of November,
2013.

 This certifies that
                    , or registered assigns, is the registered owner of the number of Rights set forth above, each of which entitles the owner
thereof, subject to the terms, provisions and conditions of the Amended and Restated Rights Agreement, dated as of December 21, 2015 (the “Rights Agreement”), between Sorrento Therapeutics, Inc., a Delaware corporation (the
“Company”), and Philadelphia Stock Transfer, Inc. (the “Rights Agent”), to purchase from the Company at any time prior to 5:00 P.M. (New York City time) on November 7, 2018 (unless such date is extended prior thereto by
the Board of Directors), at the office or offices of the Rights Agent designated for such purpose, or its successors as Rights Agent, one one-thousandth of a fully paid, non assessable share of Series A Junior Participating Preferred Stock (the
“Preferred Stock”) of the Company, at a purchase price of $40.00 per one one-thousandth of a share (the “Purchase Price”), upon presentation and surrender of this Rights Certificate with the Form of Election to Purchase and
related Certificate duly executed. The number of Rights evidenced by this Rights Certificate (and the number of shares which may be purchased upon exercise thereof) set forth above, and the Purchase Price per share set forth above, are the number
and Purchase Price as of December 21, 2015, based on the Preferred Stock as constituted at such date. The Company reserves the right to require prior to the occurrence of a Triggering Event (as such term is defined in the Rights Agreement) that
a number of Rights be exercised so that only whole shares of Preferred Stock will be issued. Capitalized terms used in this Rights Certificate without definition shall have the meanings ascribed to them in the Rights Agreement. 

Upon the occurrence of a Section 11(a)(ii) Event (as such term is defined in the Rights Agreement), if the Rights evidenced by this Rights
Certificate are beneficially owned by (i) an Acquiring Person or an Affiliate or Associate of any such Acquiring Person (as such terms are defined in the Rights Agreement), (ii) a transferee of any such Acquiring Person, Associate or
Affiliate, or (iii) under certain circumstances specified in the Rights Agreement, a transferee of a person who, after such transfer, became an Acquiring Person, or an Affiliate or Associate of an Acquiring Person, such Rights shall become null
and void and no holder hereof shall have any right with respect to such Rights from and after the occurrence of such Section 11(a)(ii) Event. 

As provided in the Rights Agreement, the Purchase Price and the number and kind of shares of Preferred Stock or other securities, which may be purchased upon
the exercise of the Rights evidenced by this Rights Certificate are subject to modification and adjustment upon the happening of certain events, including Triggering Events. 

This Rights Certificate is subject to all of the terms, provisions and conditions of the Rights Agreement, which terms, provisions and conditions are hereby
incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the Rights Agent, the Company
and the holders of the Rights Certificates, which limitations of rights include the temporary suspension of the exercisability of such Rights under the specific circumstances set forth in the Rights Agreement. Copies of the Rights Agreement are on
file at the above mentioned office of the Rights Agent and are also available upon written request to the Rights Agent. 
 This Rights Certificate, with or
without other Rights Certificates, upon surrender at the office or offices of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing Rights entitling the
holder to purchase a like aggregate number of one one-thousandths of a share of Preferred Stock as the Rights evidenced by the Rights Certificate or Rights Certificates surrendered shall have entitled such holder to purchase. If this Rights
Certificate shall be exercised in part, the holder shall be entitled to receive upon surrender hereof another Rights Certificate or Rights Certificates for the number of whole Rights not exercised. 

Subject to the provisions of the Rights Agreement, the Rights evidenced by this Rights Certificate may be redeemed by the Company at its option at a
redemption price of $0.001 per Right at any time prior to the earlier of the close of business on (i) the tenth Business Day following the Stock Acquisition Date (as such time period may be extended pursuant to the Rights Agreement), and
(ii) the Final Expiration Date. In addition, under certain circumstances following the Stock Acquisition Date, the Rights may be exchanged, in whole or in part, for shares of the Common Stock, or shares of preferred stock of the Company having
essentially the same value or economic rights as such shares. Immediately upon the action of the Board of Directors of the Company authorizing any such exchange, and without any further action or any notice, the Rights (other than Rights which are
not subject to such exchange) will terminate and the Rights will only enable holders to receive the shares issuable upon such exchange. 

  
 38 

 No fractional shares of Preferred Stock will be issued upon the exercise of any Right or Rights evidenced hereby
(other than fractions which are integral multiples of one one-thousandth of a share of Preferred Stock, which may, at the election of the Company, be evidenced by depositary receipts), but in lieu thereof a cash payment will be made, as provided in
the Rights Agreement. The Company, at its election, may require that a number of Rights be exercised so that only whole shares of Preferred Stock would be issued. 

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

 Exhibit C 

FORM OF 
 SUMMARY OF RIGHTS
TO PURCHASE 
 PREFERRED STOCK 
 On
November 7, 2013, the Board of Directors (the “Board”) of Sorrento Therapeutics, Inc., a Delaware corporation (the “Company”), authorized and declared a dividend distribution of one right (a “Right”) for each
outstanding share of the common stock of the Company, par value $0.0001 per share (the “Common Stock”), to stockholders of record at the close of business on November 18, 2013 (the “Record Date”). Each Right entitles
the registered holder to purchase from the Company a unit consisting of one one-thousandth of a share (a “Unit”) of a newly authorized series of Series A Junior Participating Preferred Stock, par value $.0001 per share (the
“Preferred Stock”), at a purchase price of $40.00 per Unit, subject to adjustment (the “Purchase Price”). The complete terms of the Rights are set forth in an Amended and Restated Rights Agreement (the “Rights
Agreement”), dated as of December 21, 2015, between the Company and Philadelphia Stock Transfer, Inc., as Rights Agent. 
 Rights Certificates;
Exercise Period. 
 Initially, the Rights will be attached to all shares of Common Stock then outstanding, and no separate rights certificates
(“Rights Certificates”) will be distributed. Subject to certain exceptions specified in the Rights Agreement, the Rights will separate from the Common Stock and a distribution date (a “Distribution Date”) will occur upon the
earlier of (i) 10 business days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of fifteen percent (15%) or more of the
outstanding shares of Common Stock (the “Stock Acquisition Date”), other than as a result of repurchases of stock by the Company or certain inadvertent actions by certain stockholders or (ii) 10 business days (or such later date as
the Board shall determine) following the commencement of a tender offer or exchange offer that would result in a person or group becoming an Acquiring Person. For purposes of the Rights Agreement, beneficial ownership is defined to include ownership
of derivative securities. 
 Until a Distribution Date, (i) the Rights will be evidenced by the certificates for the Common Stock (or, in the case of
shares reflected on the direct registration system, by the notations in the book-entry account system) and will only be transferable with such Common Stock, (ii) new Common Stock certificates issued after the Record Date will contain a legend
incorporating the Rights Agreement by reference and (iii) the surrender for transfer of any certificates for Common Stock outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such
certificates. Pursuant to the Rights Agreement, the Company reserves the right to require prior to the occurrence of a Triggering Event (as defined below) that, upon any exercise of Rights, a number of Rights be exercised so that only whole shares
of Preferred Stock will be issued. 
 The Rights are not exercisable until a Distribution Date and will expire at 5:00 P.M., New York City time on
November 7, 2018, unless such date is extended or the Rights are earlier redeemed, exchanged or terminated. 
 As soon as practicable after a
Distribution Date, Rights Certificates will be mailed to holders of record of the Common Stock as of the close of business on a Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. Except as otherwise
determined by the Board, only shares of Common Stock issued prior to a Distribution Date will be issued with Rights. 
 Flip-in Trigger. 

In the event that a person or group of affiliated or associated persons becomes an Acquiring Person, except pursuant to an offer for all outstanding shares of
Common Stock which the independent directors determine to be fair and not inadequate and to otherwise be in the best interests of the Company and its stockholders after receiving advice from one or more investment banking firms, each holder of a
Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right. Notwithstanding the
foregoing, following the occurrence of the event set forth in this paragraph, 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. However,
Rights are not 

  
 46 

 
exercisable following the occurrence of the event set forth above until such time as the Rights are no longer redeemable by the Company as set forth below. Any person who, together with its
affiliates and associates, beneficially owns 15% or more of the outstanding shares of Common Stock as of the time of the first public announcement of the Rights Agreement (an “Exempt Person”) shall not be deemed an Acquiring Person,
but only for so long as such person, together with its affiliates and associates, does not become the beneficial owner of any additional shares of Common Stock while such person is an Exempt Person. A person will cease to be an Exempt Person if such
person, together with such person’s affiliates and associates, becomes the beneficial owner of less than 15% of the outstanding shares of Common Stock. 

Flip-over Trigger. 
 In the event that, at any time
following the Stock Acquisition Date, (i) the Company engages in a merger or other business combination transaction in which the Company is not the surviving corporation, (ii) the Company engages in a merger or other business combination
transaction in which the Company is the surviving corporation and the Common Stock of the Company is changed or exchanged, or (iii) 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, each holder of a
Right (except Rights which have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right. The events
set forth in this paragraph and in the second preceding paragraph are referred to as the “Triggering Events.” 
 Exchange Feature. 

At any time after a person becomes an Acquiring Person and prior to the acquisition by such person or group of fifty percent (50%) or more of the
outstanding Common Stock, the Board may exchange the Rights (other than Rights owned by such person or group which have become null and 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). 

Equitable Adjustments. 
 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 dividend on the Preferred Stock payable in shares
of Preferred Stock, a subdivision or split of outstanding shares of Preferred Stock, a combination or consolidation of Preferred Stock into a smaller number of shares through a reverse stock split or otherwise, or reclassification of the Preferred
Stock, (ii) if holders of the Preferred Stock are granted certain rights, options or warrants to subscribe for Preferred Stock or convertible securities at less than the current market price of the Preferred Stock, or (iii) upon the
distribution to holders of the Preferred Stock of cash (excluding regular quarterly cash dividends), assets, evidences of indebtedness or of subscription rights or warrants (other than those referred to above). 

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 Units 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. 

Redemption Rights. 
 At any time until ten business days
following the Stock Acquisition Date, the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (payable in cash, Common Stock or other consideration deemed appropriate by the Board). Immediately upon the
action of the Board ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the $0.001 redemption price. 

Miscellaneous. 
 Until a Right is exercised, the holder
thereof, as such, will have no separate rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends in respect of Rights. While the distribution of

the Rights will 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 or in the event of the redemption of the Rights as set forth above. 

Amendment. 
 Any of the provisions of the Rights Agreement
may be amended by the Board prior to a Distribution Date. After a Distribution Date, the provisions of the Rights Agreement may be amended by the Board in order to cure any ambiguity, to make changes which do not adversely affect the interests of
holders of Rights, or to shorten or lengthen any time period under the Rights Agreement. Notwithstanding the foregoing, no amendment may be made at such time as the Rights are not redeemable. 

Anti-Takeover Effects. 
 The Rights may have certain
anti-takeover effects. The Rights may cause substantial dilution to any person or group that attempts to acquire the Company without the approval of the Board. As a result, the overall effect of the Rights may be render more difficult or discourage
a merger, tender offer or other business combination involving the Company that is not supported by the Board. 
 A copy of the Rights Agreement has been or
will be filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A or a Current Report on Form 8-K. 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.
