 AMENDED AND RESTATED PREFERRED SHARE PURCHASE RIGHTS PLAN, dated as of December 29, 2008 (the
“Rights Plan” or this “Agreement”), by and between Mednax, Inc., a Florida corporation (the “Company”), and Computershare Trust Company, N.A., a national banking association (the “Rights Agent”). 

RECITALS 
 WHEREAS, Mednax
Services, Inc. (“Oldco”), formerly known as Pediatrix Medical Group, Inc., and now a wholly owned subsidiary of the Company, and the Rights Agent were party to a Preferred Share Purchase Rights Plan dated as of March 31, 1999, as
amended (the “Original Rights Plan”); 
 WHEREAS, Oldco formed the Company as a wholly owned subsidiary, and in turn caused
the Company to form PMG Merger Sub, Inc. (“Merger Sub”) as a wholly owned subsidiary of the Company; 
 WHEREAS, on
December 29, 2008, Oldco, the Company, and Merger Sub entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which: (i) Oldco agreed to merge with Merger Sub (the “Merger”), thereby becoming
a wholly owned subsidiary of the Company and (ii) each shareholder of Oldco will receive shares in the Company in exchange for an equivalent number of shares in Oldco; 
 WHEREAS, pursuant to the Merger Agreement, Oldco and the Rights Agent have executed an amendment to the Original Rights Plan providing for the
expiration of the Original Rights Plan at the earlier of March 31, 2009 and the Effective Time (as defined in the Merger Agreement); 
 WHEREAS, pursuant to the Merger Agreement, the Company and the Rights Agent now desire to adopt an Amended and Restated Preferred Share Purchase Rights Plan on substantially the same terms as the Original Rights Plan; and 

WHEREAS, the Board of Directors of the Company authorized and declared effective on the date hereof a dividend of one preferred share purchase
right (a “Right”) for each share of Common Stock (as hereinafter defined) outstanding at 11:59 p.m. Eastern Standard Time on December 31, 2008, the effective time of the Merger (the “Record Date”), and has authorized the
issuance, upon the terms and subject to the conditions hereinafter set forth, of one Right (subject to adjustment) in respect of each share of Common Stock issued after the Record Date, each Right representing the right to purchase, upon the terms
and subject to the conditions hereinafter set forth, one two-thousandth (subject to adjustment) of a Preferred Share (as hereinafter defined); and 
 WHEREAS, Preferred Share shall mean a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, of the Company having the rights and preferences set forth in the Form of Articles of Amendment attached to this
Agreement as Exhibit A. 

 AGREEMENT — SHARE PURCHASE RIGHTS PLAN 
 NOW, THEREFORE, in consideration of the premises and the mutual agreements herein set forth, the parties hereby agree as follows:

 Section 1. Certain Definitions. For purposes of this Rights Plan, the following terms have the meanings indicated (capitalized
terms within any definition shall have the meanings indicated elsewhere herein with respect to such terms): 
 (a) “Acquiring
Person” shall mean any Person who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner of fifteen percent (15.0%) or more of the shares of Common Stock then outstanding. Notwithstanding the
foregoing, the term “Acquiring Person” shall not mean or include (i) the Company, 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; (ii) any Person who or which, together with all Affiliates and Associates of such Person, would be an Acquiring Person solely by reason of a reduction in the
number of issued and outstanding shares of Common Stock of the Company pursuant to a transaction or a series of related transactions voted on and approved by a Majority Director Vote (as defined below); provided, however, that in the event that such
Person described in the foregoing clause (ii) does not become an Acquiring Person by reason of the foregoing clause (ii), such Person shall nonetheless become an Acquiring Person in the event such Person thereafter acquires Beneficial Ownership
of an additional 1.0% of the issued and outstanding Common Stock of the Company, unless such additional Common Stock ownership results solely from a subsequent reduction in the number of issued and outstanding shares of Common Stock of the Company
pursuant to a transaction or a series of related transactions approved by a Majority Director Vote; (iii) any Person who or which, together with all Affiliates and Associates of such Person, would be an Acquiring Person solely by reason of a
transaction in which the Company (or one or more of its Subsidiaries) acquires a business (whether such acquisition is accomplished by means of a purchase of stock or assets, a merger, share exchange or otherwise) owned by such Person in exchange
(in whole or in part) for shares of Common Stock of the Company pursuant to a transaction (or a series of related transactions) approved by a Majority Director Vote (an “Approved Acquisition Transaction”); provided, however, that in the
event that such Person described in the foregoing clause (iii) does not become an Acquiring Person by reason of the foregoing clause (iii), such Person shall nonetheless become an Acquiring Person in the event such Person thereafter acquires
Beneficial Ownership of an additional 1.0% of the issued and outstanding Common Stock of the Company, unless such additional Common Stock ownership results solely from a reduction in the number of issued and outstanding shares of Common Stock of the
Company (such as that described in clause (ii) above), or a subsequent Approved Acquisition Transaction, pursuant to a transaction or a series of related transactions approved by a Majority Director Vote; or (v) any Person that on the date
of this Rights Agreement is the Beneficial Owner of fifteen percent (15%) or more of the outstanding Common Stock unless and until such Person becomes the Beneficial Owner of an additional one percent (1%) or more of the outstanding Common
Stock. 
  

 2 

 Notwithstanding the foregoing, if the Board of Directors of the Company determines in good faith that a
Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provision, has become such inadvertently, and such Person divests as promptly as practicable a sufficient number of shares of Common Stock so that
such Person would no longer be an “Acquiring Person,” as defined pursuant to the foregoing provisions, then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement. 
 (b) “Acquiring Person Transferee” shall have the meaning set forth in Section 7(e) hereof. 
 (c) “Act” shall mean the Securities Act of 1933, as amended. 
 (d) “Affiliate” shall have the meaning ascribed to such term in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

 (e) “Associate” shall have the meaning ascribed to such term in Rule 12b-2 of the General Rules and Regulations under the
Exchange Act. 
 (f) A Person shall be deemed the “beneficial owner” of, and shall be deemed to “beneficially own”, any
securities: 
 (i) which such Person or any of such Person’s Affiliates or Associates beneficially owns, directly or
indirectly; 
 (ii) which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the
right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (whether or not in writing) or upon the exercise of conversion rights, exchange rights, rights
(other than these 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 or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange; or (B) any security with respect to which such person has the right to vote
pursuant to any agreement, arrangement or understanding, if the agreement, arrangement or understanding to vote such security (1) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent
solicitation made pursuant to, and in accordance with, the applicable rules and regulations promulgated under the Exchange Act, and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report);
or 
 (iii) which are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof)
with which such Person (or any of such Persons 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
proviso (B) to subparagraph (ii) of this Section 1(f)) or disposing of any voting securities of the Company; provided, however, that nothing in this Section 1(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 after the
date of such acquisition. 
  

 3 

 Notwithstanding anything in this definition of Beneficial Ownership to the contrary, the phrase
“then outstanding,” when used with reference to a Person’s Beneficial Ownership of securities of the Company, shall mean the number of such securities then issued and outstanding, together with the number of such securities not then
actually issued and outstanding which such Person would be deemed to own beneficially hereunder. 
 (g) “Business day” shall mean
any day other than a Saturday, Sunday or a day on which banking institutions in the Commonwealth of Massachusetts are authorized or obligated by law or executive order to close. 
 (h) “Close of business” on any given date shall mean 5:00 P.M., Eastern time, on such date; provided, however, that if such date is not a
Business Day it shall mean 5:00 P.M., Eastern time, on the next succeeding day which is a Business Day. 
 (i) “Common Stock” shall
mean the common stock, par value $0.01 per share, of the Company, except that “Common Stock” when used with reference to any Person other than the Company shall mean the capital stock of such Person with the greatest voting power, or the
equity securities or other equity interest having power to control or direct the management, of such Person. 
 (j) “Current market
price” shall have the meaning set forth in Section 11(d) hereof. 
 (k) “Distribution Date” shall have the meaning set
forth in Section 3(a) hereof. 
 (l) “Exchange Act” shall have the meaning set forth in Section 1(d) hereof. 

(m) “Exchange Ratio” shall have the meaning set forth in Section 11(r)(i) hereof. 
 (n) “Expiration Date” shall have the meaning set forth in Section 7(a) hereof. 
 (o) “Final Expiration Date” shall have the meaning set forth in Section 7(a) hereof. 
 (p) “Independent Director” shall mean any member of the Company’s Board of Directors, while such person is a member of the Board, who
(i) is not an Acquiring Person or an Affiliate or Associate of an Acquiring Person, (ii) is not an employee or officer of the Company or an employee, officer or director of any Acquiring Person, and (iii) is not a relative or spouse
of (A) an Acquiring Person, (B) any officer or other person employed in a management position with the Company or with any Acquiring Person or (C) any director of any Acquiring Person. For the avoidance of doubt, a director meeting
the foregoing definition of an Independent Director shall be an Independent Director irrespective of whether, and shall not be deemed an Affiliate or Associate of an Acquiring Person solely because, such director was (x) elected following a
Special Vote Event (as defined below), (y) nominated for election as a director by, or received votes (either at a meeting of shareholders or pursuant to a written consent in lieu of a meeting of shareholders) in favor of such election as a
director from, an Acquiring Person or an Affiliate or Associate of an Acquiring Person or (z) appointed to fill a vacancy on the Board by a vote of the Board including directors who are not Independent Directors. 
  

 4 

 (q) “Majority Director Vote” shall mean (whether the reference relates to a determination,
approval or vote of the Board of Directors, the Company or certain of the directors of the Company) the affirmative vote and approval of the directors of the Company (duly elected or appointed in accordance with the Company’s By-laws)
constituting a majority in number of the total number of directors then constituting the Company’s Board of Directors (as authorized in accordance with the Company’s By-laws); provided, however, that if a Majority Director Vote is required
or taken hereunder (or otherwise pursuant to this Agreement) at any time on or after a Special Vote Event (as defined below) shall have occurred, then, in addition to such vote and approval of the full Board of Directors, the vote and approval of a
majority of the Independent Directors, if any, shall also be required. For purposes of this Agreement, a “Special Vote Event” shall mean and include either (or the earlier of) (i) the time any Person becomes an Acquiring Person, or
(ii) the date of a change, resulting from a proxy or consent solicitation, in a majority of the directors of the Company in office at the commencement of such solicitation, if any Person who is a participant in such solicitation has stated (or,
if upon the commencement of such solicitation, a majority of the Board of Directors of the Company has determined in good faith) that such Person (or any of its Affiliates or Associates) intends to take, or may consider taking, any action which
would result in such Person becoming an Acquiring Person or which would cause the occurrence of a Triggering Event. To the extent permitted or required under Florida law, the authorization and approval of this Agreement by the Company’s Board
of Directors shall also constitute the authorization and approval of the special quorum and vote requirements with respect to the directors of the Company (including any requirement with regard to a vote by or approval of Independent Directors), as
set forth or provided in this Agreement. 
 (r) “Person” shall mean any individual, firm, company, corporation, partnership, trust

 5

purposes of this definition, shall include a report filed pursuant to the Exchange Act) by the Company or an Acquiring Person that a Person has become an Acquiring Person.

 (dd)
“Summary of Rights” shall have the meaning set forth in Section 3(b) hereof. 
 (ee) “Trading Day” shall have the
meaning set forth in Section 11(d) hereof. 
 (ff) “Triggering Event” shall mean (or, as the case may be, the earliest of) a
Section 11(a)(ii) Event or any Section 13 Event. 
 Section 2. Appointment of Rights Agent. The Company hereby appoints the
Rights Agent to act as agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such other Agents or Co-Rights Agents as it may deem
necessary or desirable, upon ten (10) days’ prior written notice to the Rights Agent. The Rights Agent shall have no duty to supervise, and shall in no event be liable for, the acts or omissions of any such co-Rights Agent. 
 Section 3. Issuance of Rights Certificates. 
 (a) Rights shall be issued in respect of all shares of Common Stock of the Company outstanding on the Record Date. Until the earlier of (i) the close of business on the tenth day after the Stock Acquisition Date (or, if the tenth day
after such date occurs before the Record Date, the close of business on the Record Date), or (ii) the close of business on the tenth business day (or such later date as may be determined by a Majority Director Vote prior to such time as any
Person becomes an Acquiring Person) after the date of the commencement 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 or entity
organized, appointed or established by the Company for or pursuant to the terms of any such plan) of, or of the first public announcement of the intention of 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 or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan) to commence, a tender or exchange offer the consummation of which
would result in any Person becoming the beneficial owner of shares of Common Stock of the Company aggregating 15% or more of the then outstanding shares of Common Stock of the Company (including any such date which is after the date of this
Agreement and prior to the issuance of the Rights) (the earlier of such dates referred to in clauses (i) and (ii) of this sentence being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced
(subject to the provisions of paragraph (b) of this Section 3) by the certificates for the Common Stock of the Company registered in the names of the holders thereof (which certificates shall be deemed also to be Rights Certificates) and
not by separate certificates or, to the extent that Common Stock of the Company is issued in uncertificated form, by the notation of the ownership of shares of Common Stock of the Company in any book entry system that establishes the ownership of
any 

  

 6 

 
such shares of Common Stock of the Company, and (y) the Rights (and the right to receive Rights Certificates) will be transferable only in connection
with the transfer of the underlying shares of Common Stock of the Company (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
Company will send or cause to be sent (and the Rights Agent, if requested, will send) by first-class, insured, postage prepaid mail, to each record holder of the Common Stock of the Company 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 certificate(s), in substantially the form attached hereto as Exhibit B (the “Rights Certificates”), evidencing one Right for each share of Common Stock so
held (subject to adjustment as provided herein). 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 the Distribution Date, the Rights will be evidenced solely by the Rights Certificates. 
 (b) With respect to certificates for
the Common Stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates for the Common Stock and the registered holders of the Common Stock shall also be the registered holders of the
associated Rights. Until the Distribution Date (or the earlier of the Redemption Date or the Final Expiration Date), the transfer (or surrender for transfer) of any certificates representing shares of Common Stock outstanding on the Record Date
shall also constitute the transfer of the Rights associated with the shares of Common Stock represented thereby. 
 (c) Rights shall also be
issued (consistent with the provisions of subsection (a) of this Section 3) in respect of all shares of Common Stock of the Company which are issued after the Record Date but prior to the earliest of the Distribution Date, the Redemption
Date or the Final Expiration Date. Certificates for shares of Common Stock (including, without limitation, any reacquired shares referred to in the last sentence of this Section 3(c)) which become outstanding after the Record Date but prior to
the earliest of the Distribution Date, the Redemption Date or the Final Expiration Date shall have impressed on, printed on, written on or otherwise affixed to them the following legend: 
 “This certificate also evidences and entitles the holder hereof to certain rights as set forth in an Amended and Restated Preferred
Share Purchase Rights Plan between Mednax, Inc. (the “Company”) and Computershare Trust Company, N.A., as Rights Agent (the “Rights Agent”), dated as of December 29, 2008, as it may be amended from time to time (the
“Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Agreement, such Rights (as
defined in the Agreement) 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 Agreement, as in effect on the date of mailing, without
charge after the receipt of a written request therefor. Under certain circumstances set forth in the Agreement, Rights issued to, or held or beneficially owned by, any Person who becomes an Acquiring Person (as such terms are defined in the
Agreement), whether currently held by or on behalf of such Person or by any subsequent holder, become null and void.” 
  

 7 

 With respect to such certificate(s) containing the foregoing legend, until the Distribution Date, the
Rights associated with the Common Stock of the Company represented by such certificate(s) shall be evidenced by such certificate(s) alone, and the surrender for transfer of any such certificate(s) shall also constitute the transfer of the Rights
associated with the shares of Common Stock of the Company represented thereby or, to the extent that Common Stock of the Company is issued in uncertificated form, by the notation of the ownership of shares of Common Stock of the Company in any book
entry system that establishes the ownership of any such shares of Common Stock of the Company. In the event that the Company purchases or acquires any Common Stock of the Company after the Record Date but prior to the Distribution Date, any Rights
associated with such reacquired Common Stock of the Company shall be deemed cancelled and retired so that the Company shall not be entitled to exercise any Rights associated with the shares of Common Stock of the Company which are no longer
outstanding. 
 Section 4. Form of Rights Certificates. 
 (a) The Rights Certificates (and the forms of election to purchase Preferred Shares and of assignment to be printed on the reverse thereof) shall each be in substantially the form attached hereto as Exhibit B and may
have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Rights Plan, or as may be required to comply
with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or stock quotation or trading system on which the Rights may from time to time be listed or quoted for trading, or to
conform to 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 shall entitle the holders thereof to purchase such number of one
two-thousandths of a Preferred Share as shall be set forth therein at the price per one two-thousandth of a Preferred Share set forth therein (as determined in accordance with Section 7(b) hereof, the “Purchase Price”), but the number
and type of securities purchasable upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment as provided herein. 
 (b) Any Rights Certificate issued pursuant to Section 3(a) or Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring Person or any Associate or Affiliate thereof, (ii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a
transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring
Person or to any Person with whom such Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors (or directors, as the case may be) of the
Company, by a Majority Director Vote, has determined, in its sole discretion, is part of a plan, scheme, arrangement or understanding which has as a primary purpose or effect the avoidance or 

  

 8 

 
circumvention 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 (to the extent feasible) the following legend: 
 “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 thereof (as such terms are defined in an Amended
and Restated Preferred Share Purchase Rights Plan between Mednax, Inc. (the “Company”) and Computershare Trust Company, N.A., as Rights Agent (the “Agreement”). Accordingly, this Rights Certificate and the Rights represented
hereby become null and void in the circumstances specified in Section 7(e) of the Agreement. The Company will mail to the holder of this certificate a copy of the Agreement, as in effect on the date of mailing, without charge after the receipt
of a written request therefor.” 
 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 or its President, either
manually or by facsimile signature, and shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile signature. The Rights Certificates shall be manually or by facsimile signature countersigned by the
Rights Agent and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall have signed any of the Rights Certificates shall cease to be such officer of the Company before countersignature by the Rights
Agent and issuance and delivery by the Company, such Rights Certificates, nevertheless, may be countersigned by the Rights Agent and issued and delivered by the Company with the same force and effect as though the person who signed such Rights
Certificates had not ceased to be such officer of the Company; and any Rights Certificates may be signed on behalf of the Company by any person who, at the actual date of the execution of such Rights Certificate, shall be a proper officer of the
Company authorized to sign such Rights Certificate, although at the date of the execution of this Rights Plan any such person was not such an officer. 
 (b) Following the Distribution Date, the Rights Agent will keep or cause to be kept, at its principal office or offices designated as the appropriate place for surrender of Rights Certificates upon exercise or
transfer, books for registration and transfer of the Rights Certificates issued hereunder. Such books shall show the name 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 earlier of the Redemption Date and the Final Expiration Date, any Rights Certificate or
Rights Certificates (other than any Right Certificates representing Rights that have become void pursuant to Section 7(e) hereof or that have been exchanged pursuant to 

  

 9 

 
Section 11(r) hereof) may be transferred, split up, combined or exchanged for another Rights Certificate or Certificates, entitling the registered holder
thereof to purchase a like number of shares of one two-thousandths of a Preferred Share as the Rights Certificate or Certificates surrendered then entitled such holder (or former holder in the case of a transfer) to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or Certificates shall make such request in writing delivered to the Rights Agent and shall surrender the Rights Certificate or Certificates to be transferred, split up,
combined or exchanged at the principal office or offices of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the
Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request. Thereupon the Rights Agent shall, subject to Section 4(b), Section 7(e) and Section 14 hereof, countersign and
deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection
with any transfer, split up, combination or exchange of Rights Certificates. 
 (b) Upon receipt by the Company and the Rights Agent of
evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Rights Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and reimbursement to the Company
and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Rights Certificate if mutilated, the Company will execute and deliver a new Rights Certificate of like tenor to the
Rights Agent for countersignature and delivery to the registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated. 
 Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights. 
 (a) Subject to Sections 7(e), 11 and 13 and
other provisions hereof, the registered holder of any Rights Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein including, without limitation, the restrictions on exercisability set forth in Section 9(c)
and Section 23(a) hereof), in whole or in part, at any time after the Distribution Date, upon surrender of the Rights Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed, to the
Rights Agent at the principal office of the Rights Agent designated for such purpose, together with payment of the aggregate Purchase Price for each one two-thousandth of a Preferred Share (or other securities) as to which the Rights evidenced by
such Rights Certificate are exercised, at or prior to the earliest of (i) the close of business on March 31, 2009 (the “Final Expiration Date”), the time at which the Rights are redeemed as provided in Section 23 hereof (the
“Redemption Date”), or (iii) the time at which the Rights are exchanged as provided in Section 11(r) hereof (the earliest of (i), (ii) and (iii) being sometimes herein referred to as the “Expiration Date”).

 (b) The Purchase Price for each one two-thousandth of a Preferred Share purchasable pursuant to the exercise of a Right shall initially be
$75.00, and shall be subject to adjustment from time to time as provided in Section 11 or 13 hereof, and shall be payable in lawful money of the United States of America in accordance with paragraph (c) below. 
  

 10 

 (c) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to
purchase and the certificate duly executed, accompanied by payment of the Purchase Price for each share to be purchased upon exercise of such Rights, as set forth below, and an amount equal to any applicable transfer tax required to be paid by the
holder of such Rights Certificate, the Rights Agent shall, subject to Section 20(j) hereof, thereupon promptly (i) (A) requisition from any transfer agent of the Preferred Shares or other securities to be purchased (or make available,
if the Rights Agent is the transfer agent for such shares) certificates for the total number of shares 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, in its sole discretion, to deposit the total number of shares issuable upon exercise of the Rights hereunder with a depositary agent, requisition from the depositary agent depositary receipts representing such number of shares as
are to be purchased (in which case certificates for the shares 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 appropriate, requisition from the Company the amount of cash, if any, to be paid in lieu of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such certificates or depositary receipts, cause the
same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, and (iv) when appropriate, 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 and any applicable transfer taxes shall be made in cash or by certified bank check or cashier’s check payable to the Company. 

(d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the registered holder of such Rights Certificate, registered in such name or names as may be designated by
such holder, subject to the provisions of Section 14 hereof. 
 (e) Notwithstanding anything in this Rights Plan to the contrary, from
and after the occurrence of a Section 11(a)(ii) Event, any Rights that are or were acquired or beneficially owned by an Acquiring Person (or any Associate or Affiliate of such Acquiring Person) or an Acquiring Person Transferee (as such term is
defined below in this Section 7(e)), shall be and become null and void without any further action, and no holder of such Rights (or of Rights Certificates evidencing such Rights) shall have any rights whatsoever with respect to such Rights
(including, without limitation, any rights to exercise such Rights), whether under any provision of this Rights Plan or otherwise. The Company shall use all reasonable efforts to ensure that the provisions of this Section 7(e) and
Section 4(b) hereof are complied with, but shall have no liability to any holder of Rights Certificates or any other Person as a result of its failure to make any determinations with respect to an Acquiring Person or their respective
Affiliates, Associates or Acquiring Person Transferees hereunder. No Rights Certificate(s) shall be issued pursuant to Section 3 hereof that represents Rights beneficially owned by an Acquiring Person (or any Associate or Affiliate thereof or
any Acquiring Person Transferee) whose Rights would be null and void pursuant to the preceding sentence; in addition, no Rights Certificate(s) shall be issued 

  

 11 

 
at any time upon the transfer of any Rights to an Acquiring Person (or any Associate or Affiliate thereof or any Acquiring Person Transferee) whose Rights
would be null and void pursuant to the preceding sentence; and any Rights Certificate(s) delivered to the Rights Agent for transfer to an Acquiring Person (or any Associate or Affiliate thereof or any Acquiring Person Transferee) whose Rights would
be null and void pursuant to the preceding sentence shall be cancelled. For purposes of this Agreement, the term “Acquiring Person Transferee” shall mean and include, with respect to Rights (whether or not attached to shares of Common
Stock), (i) a transferee of an Acquiring Person (or of any Associate or Affiliate of such Acquiring Person) who becomes a transferee after the Acquiring Person becomes such, or (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders
of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights, or (B) a transfer which the Board of Directors of the
Company has determined, in its sole discretion, is part of a plan, scheme, arrangement or understanding which has as a primary purpose or effect the avoidance or circumvention of this Section 7(e). 
 (f) Notwithstanding anything in this Rights Plan 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 completed and signed the certificate contained in the form of election to purchase set
forth on the reverse side of the Rights Certificate surrendered for such exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request. 
 Section 8. Cancellation and Destruction of Rights Certificates. All Rights Certificates surrendered for
the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or any of its agents, be delivered to the Rights Agent for cancellation or in 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 Rights Plan. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights
Agent shall so cancel and retire, any other Rights Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Rights Certificates to the Company, or shall, at the written
request of the Company, destroy such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company. 
 Section 9. Reservation and Availability of Preferred Shares. 
 (a) Subject to the Company’s
rights in Section 11(q) or elsewhere herein to otherwise fulfill its obligations hereunder, the Company covenants and agrees that, from and after the Distribution Date, it will cause to be reserved and kept available out of its authorized and
unissued Preferred Shares or any Preferred Shares held in its treasury, the number of Preferred Shares that, as provided in this Rights Plan, will be sufficient to permit the exercise in full of all outstanding Rights; provided, however, that the
Company shall not be required to reserve and 

  

 12 

 
keep available shares of Common Stock or other securities sufficient to permit the exercise in full of all outstanding Rights pursuant to the adjustments set
forth in Section 11(a)(ii) or Section 13 hereof unless the Rights become exercisable pursuant to such adjustments. 
 (b) So long
as the Common Stock is listed on any national securities exchange or listed or registered for quotation on any other market (including, without limitation, the NASDAQ Stock Market (“NASDAQ”)), the Company shall use its best efforts to
cause, from and after such time as the Rights become exercisable, all Preferred Shares and/or other securities issuable pursuant to outstanding Rights 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 and as 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 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 date
of the expiration or termination of the Rights. The Company will also take such action as may be appropriate under, or to ensure compliance with, the securities or “blue sky” laws of the various states in connection with the exercisability
of the Rights. The Company may temporarily suspend, for a period or periods of time from time to time, not to exceed ninety (90) days in the aggregate 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 such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has
been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. Notwithstanding any provision of this Rights Plan to the contrary, the Rights shall not be exercisable in any jurisdiction unless or
until the requisite qualification in such jurisdiction shall have been obtained. 
 (d) The Company covenants and agrees that it will take
all such action as may be necessary to ensure that all shares delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price therefore), be duly and validly authorized
and issued and fully paid and nonassessable shares. 
 (e) The Company further covenants and agrees that it will pay when due and payable any
and all federal and state transfer taxes and charges which may be payable in respect of the issuance or delivery of the Rights Certificates and of any certificates for shares issued upon the exercise of Rights. The Company shall not, however, be
required to pay any transfer tax 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 shares 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 shares in a name other than that of the registered holder upon the exercise of any Rights until such tax shall have been paid (any such tax
being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax is due. 
  

 13 

 Section 10. Preferred Stock Record Date. Each person in whose name any certificate for a number of
Preferred Shares or shares of Common Stock (or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of such shares represented thereby on, and such
certificates shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and all applicable transfer taxes) was made; provided, however, that if the date of such surrender
and payment is a date upon which the share transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the
share 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 shareholder of the Company with respect to shares for which the Rights
shall be exercisable, including, without limitation, the right to vote (or consent with respect thereto), to transfer, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice
of any meeting or proceeding of the Company, except as provided herein. 
 Section 11. Adjustment of Purchase Price; Number and Kind of
Shares or Number of Rights; Exchange of Rights for Shares of Common Stock. 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 Common Stock payable in shares of Common Stock, (B) subdivide the outstanding shares of Common Stock, (C) combine the outstanding Common Stock into a smaller number of shares, or (D) issue any shares of its capital stock in a
reclassification of the Common 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) or
Section 7(e) hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of shares of capital stock issuable on
such date, shall be appropriately and proportionately adjusted (including applicable adjustments under paragraph (p) of this Section 11) 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 capital stock which, if such Right had been exercised immediately prior to such date and at a time when the 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, combination or reclassification; provided, however, that in no event shall the consideration to be paid upon the exercise of any Right be less
than the aggregate par value of the shares of capital stock of the Company issuable upon exercise of such Right. 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) In the event that, at any time after the Record Date, any Person shall become an Acquiring Person (such event being referred to
herein as a “Section 11(a)(ii) Event”), then, subject to Sections 11(r) and 23(a) and except as otherwise provided in this Section 11, each holder of a Right (except as provided in Section 7(e) hereof) shall thereafter have the
right 

  

 14 

 
to receive, in accordance with the terms of this Agreement, upon exercise thereof at a price equal to the then current Purchase Price multiplied by the
number of one two-thousandths of a Preferred Share for which the Right is then exercisable, 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 number
of one two-thousandths of a Preferred Share for which a Right was exercisable immediately prior to the first occurrence of the Section 11(a)(ii) Event, and dividing that product by (y) 50% of the then current market price (as determined
pursuant to Section 11(d) hereof) per share of the Common Stock of the Company on the date of the occurrence of such Section 11(a)(ii) Event. In the event that there shall not be sufficient shares of Common Stock authorized or available
for issuance to permit the exercise in full of the Rights in accordance with this Section 11(a)(ii), the Company shall take all such action as may be necessary to authorize additional shares of Common Stock for issuance upon exercise of the
Rights. In the event the Company shall, after good faith effort, be unable to take all such action as may be necessary to authorize such additional shares of Common Stock, the Company shall substitute, for each share of Common Stock that would
otherwise be issuable upon exercise of a Right, a number of Preferred Shares or fraction thereof such that the current market price (as defined in paragraph (d) below) of one Preferred Share multiplied by such number or fraction is equal to the
current market price of one Common Share as of the date of issuance of such Preferred Shares or fraction thereof. In the event that any Person shall become an Acquiring Person and the Rights shall then be outstanding, the Company shall not take any
action which would eliminate or diminish the benefits intended to be afforded by the Rights as provided under this Agreement. 
 (b) In case
the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Common Stock entitling them (for a period expiring within forty-five (45) calendar days after such record date) to subscribe for or purchase
Common Stock (or shares having the same rights, privileges and preferences as the shares of Common Stock (“equivalent common stock”)) or securities convertible into Common Stock or equivalent common stock at a price per share of Common
Stock or per share of equivalent common stock (or having a conversion price per share, if a security convertible into Common Stock or equivalent common stock) less than the current market price (as determined pursuant to Section 11(d) hereof)
per share of Common 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 Common Stock outstanding on such record date, plus the number of shares of Common Stock which the aggregate offering price of the total number of shares of Common Stock and/or equivalent common 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 Common Stock outstanding on such record date,
plus the number of additional shares of Common Stock and/or equivalent common stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible); provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon exercise of one Right. In case such subscription price may be paid by delivery of
consideration part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the
Rights Agent and shall be 

  

 15 

 
binding on the Rights Agent and the holders of the Rights. Shares of Common 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. 
 (c) In case the Company shall fix a record date for a
distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness, cash (other than a regular quarterly
cash dividend out of the earnings or retained earnings of the Company), assets (other than a dividend payable in Common Stock, but including any dividend payable in stock other than Common Stock) or subscription rights or warrants (excluding those
referred to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be
the current market price (as determined pursuant to Section 11(d) hereof) per share of Common Stock on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall
be described in a statement filed with the Rights Agent) 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 Common Stock, and the denominator of
which shall be such current market price (as determined pursuant to Section 11(d) hereof) per share of Common Stock; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon exercise of one Right. 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) For
the purpose of any computation hereunder, the “current market price” per Preferred Share (subject to the second paragraph of this paragraph (d)) or share of Common Stock (or per share of any other security) on any date shall be deemed to
be the average of the daily closing prices per share of such security for the thirty (30) consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; provided, however, that in the event that the current
market price per share of the security is determined during a period following the announcement by the issuer of such security of (A) a dividend or distribution on such security payable in shares of such security or securities convertible into
shares of such security (other than the Rights), or (B) any subdivision, combination or reclassification of such security, and prior to the expiration of the requisite thirty (30) Trading Day period after the ex-dividend date for such
dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the “current market price” shall be properly adjusted to take into account ex-dividend 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 New York Stock Exchange or, if the security in question is not listed or admitted to 

  

 16 

 
trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the
principal national securities exchange on which the security is listed or admitted to trading or, if the security is 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 security in question is 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 security selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the security, the fair value of such shares on such
date as determined in good faith by the Board of Directors of the Company shall be used. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the security in question is listed or admitted to
trading is open for the transaction of business or, if the security is not listed or admitted to trading on any national securities exchange, a Business Day. If the security is not publicly held or not so listed or traded, “current market
price” per share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all
purposes of this Rights Plan. 
 For the purpose of any computation hereunder, the “current market price” per Preferred Share shall
be determined in accordance with the preceding paragraph. However, if the Preferred Shares are not publicly traded, the “current market price” of a Preferred Share shall be conclusively deemed to be the current market price per share of
the Common Stock as determined pursuant to the preceding paragraph (appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof), multiplied by one thousand. 
 (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 (1.0%) 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 one-millionth of a Preferred Share or one-thousandth of a share of Common Stock or other share 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 requires such adjustment, or the date of
the expiration of the right to exercise any Rights. 
 (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 or fraction of a share of capital stock other than Common Stock, thereafter the number or fraction 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 Common 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 Common Stock shall apply on like terms to any such other shares. 
  

 17 

 (g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price
or otherwise hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of (or fraction of) Preferred Shares or shares of Common Stock or other securities purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein. 
 (h) Unless the Company shall have exercised its election as provided in
Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase,
at the adjusted Purchase Price, that number of one two-thousandths of a Preferred Share (calculated to the nearest one-millionth) obtained by (i) multiplying (x) the number of one two-thousandths of a Preferred 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 two-thousandths of a Preferred Share 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 two-thousandths of a Preferred Share of Common 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-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall
make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase
Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least ten (10) days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the
number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14
hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights
Certificates held by such holders prior to the date of adjustment, and 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 two-thousandths of a Preferred Share issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Purchase Price and the number of one
two-thousandths of a Preferred Share which were expressed in the initial Rights Certificates issued hereunder. 
  

 18 

 (k) Before taking any action that would cause an adjustment reducing the Purchase Price below one
two-thousandth of the then stated or par value, if any, of the Preferred Shares issuable upon exercise of the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue such number of duly authorized, fully paid and nonassessable Preferred Shares (or shares of Common Stock or other securities issuable thereunder, as the case may be) at such adjusted Purchase Price. 
 (l) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Preferred Shares or shares of Common Stock or other capital stock or securities
of the Company, if any, issuable upon such exercise over and above the number of Preferred Shares or shares of Common 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 the Board of Directors of the Company shall
determine in good faith by a Majority Director Vote to be advisable in order that any (i) consolidation or subdivision of the Common Stock, (ii) issuance wholly for cash of any shares of Common Stock at less than the current market price,
(iii) issuance wholly for cash of shares of Common Stock or securities which by their terms are convertible into or exchangeable for shares of Common 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 Common Stock shall not be taxable to such shareholders. 
 (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 or earning power aggregating 50% or more of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its
Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), if (x) at the time of or immediately after such consolidation, merger 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
shareholders of 

  

 19 

 
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 or Section 26 hereof or otherwise specifically permitted by this Rights Plan, take (or permit any Subsidiary to take) any action if at the time such action is taken it is
reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights. 
 (p) Anything in this Rights Plan to the contrary notwithstanding, in the event that the Company shall at any time after the Record 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, then, (A) in any such case the Purchase Price shall be
adjusted by multiplying the Purchase Price in effect prior to such occurrence by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately before such event and the denominator of which is the number of
shares of Common Stock outstanding immediately after such event, and (B) each share of Common Stock outstanding immediately after such event shall have issued with respect to it that number of Rights which each share of Common Stock outstanding
immediately prior to such event had issued with respect to it. The adjustments provided for in this Section 11(p) shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination or consolidation is
effected. 
 (q) In lieu of issuing shares of Common Stock (and/or Preferred Shares) in accordance with Section 11(a)(ii) hereof, the
Board of Directors may, if the number of shares of Common Stock which are authorized by the Company’s Articles of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is not sufficient
to permit the exercise in full of the Rights in accordance with Section 11(a)(ii) hereof, the Board of Directors shall, to the extent permitted by applicable law and any material agreements then in effect to which the Company is a party,
(A) determine the value of the shares of Common Stock (the “Adjustment Shares”) issuable upon the exercise of a Right immediately after the adjustments provided for in Section 11(a)(ii) (the “Current Value”), and
(B) with respect to each Right (other than Rights which have become void pursuant to the provisions hereof), make adequate provision to substitute for any or all such Adjustment Shares, upon payment of the applicable Purchase Price,
(1) cash, (2) other equity securities of the Company (including, without limitation, shares, or units of shares, of preferred stock which are deemed in good faith by the Board of Directors to have substantially the same value as shares of
Common Stock (such shares or units of shares of preferred stock are herein called “Common Stock equivalents”)), (3) debt securities of the Company, (4) other assets, (5) a reduction of the Purchase Price, or (6) any
combination of the foregoing having a value which, when added to the value of the shares of Common Stock (and/or Preferred Shares) actually issued upon exercise of such Right, shall have an aggregate value equal to the Current Value, where such
aggregate value has been determined in good faith by the Board of Directors based upon the advice of a nationally recognized independent investment banking firm selected in good faith by the Board of Directors; provided that if the Company shall not
have made adequate provision to deliver 

  

 20 

 
value pursuant to clause (B) above within thirty (30) days following the date (the “Section 11(a)(ii) Trigger Date”) which is 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, 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 Preferred Shares and then, if necessary, cash, which shares and cash have an aggregate value equal to the excess of
(x) the Current Value over (y) the Purchase Price for the number of shares (or fraction of a share) for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event. If, upon the occurrence of a
Section 11(a)(ii) Event, the number of shares of Common Stock that are authorized by the Company’s Articles of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights are not
sufficient to permit exercise in full of the Rights in accordance with Section 11(a)(ii) hereof, and if the Board of Directors shall determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized
for issuance upon exercise in full of the Rights, then, if the Board of Directors so elects, the thirty (30) day period set forth above may be extended to the extent necessary, but not more than ninety (90) days after the
Section 11(a)(ii) Trigger Date, in order that the Company may seek shareholder 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 some action must be taken pursuant to the first or second sentence of this Section 11(q), the Company (x) shall provide, subject to Section 7(e) hereof and the last
sentence of this Section 11(q), that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of
additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that
the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such times as the suspension is no longer in effect. For purposes of this Section 11(q), the value of the Common Stock shall be the current
market price per share of the 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. The Board of Directors may, but shall not be required to, establish procedures to allocate the right to receive Common Stock upon the exercise of the Rights among holders of Rights pursuant to this Section 11(q). 
 (r) (i) The Board of Directors of the Company may, at its option upon approval by a Majority Director Vote, at any time after any Person becomes an
Acquiring Person, exchange shares of Common Stock for all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 7(e) hereof), at an exchange ratio of
one (1.0) share of Common Stock per Right, appropriately adjusted to reflect any adjustment in the number of Rights pursuant to Section 11(i) hereof (such exchange ratio being hereinafter referred to as the “Exchange Ratio”).
Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than the Company, any Subsidiary of the Company, any employee benefit plan of the Company or any such
Subsidiary, or any entity holding Common Stock for or pursuant to the 

  

 21 

 
terms of any such plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the shares of Common
Stock then outstanding. 
 (ii) Immediately upon the action of the Board of Directors of the Company ordering the exchange of
any Rights pursuant to paragraph (i) of this Section 11(r) and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to
receive that number of shares of Common Stock equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice of any such exchange; provided, however, that the failure to give,
or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the
Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange 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 which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions
of Section 7(e) hereof) held by each holder of Rights. 
 (iii) In the event that there shall not be sufficient shares of
Common Stock available for issuance to permit any exchange of Rights as contemplated in accordance with this Section 11(r), the Company shall either take such action as may be necessary to authorize additional shares of Common Stock for
issuance upon exchange of the Rights or, alternatively, at the option and in the sole discretion of the Board of Directors (or directors, as the case may be), approved by a Majority Director Vote, in lieu of issuing Common Stock in exchange for each
such Right, (x) pay cash in an amount equal to the Current Value (as hereinafter defined), (y) issue debt or equity securities or a combination thereof (which may include Preferred Shares), having a value equal to the Current Value, where
the value of such securities shall be determined by the Board of Directors in good faith based upon the advice of a nationally recognized investment banking firm selected by the Board of Directors, or (z) deliver any combination of cash,
property, Common Stock and/or other securities having a value equal to the Current Value (again, where the value of such securities shall be determined by the Board of Directors in good faith based upon the advice of a nationally recognized
investment banking firm selected by the Board of Directors). For purposes of this paragraph (iii) only, the term “Current Value” shall mean the product of the current market price per share of Common Stock (determined pursuant to
Section 11(d) as of the Stock Acquisition Date) multiplied by the number of shares of Common Stock for which the Right otherwise would be exchangeable if there were sufficient shares available. To the extent that the Company determines that
some action need be taken pursuant to clauses (x), (y) or (z) of this paragraph (iii), the Board of Directors may temporarily suspend the exercisability of the Rights for a period of up to ninety (90) days following the Stock
Acquisition Date, in order to seek any authorization of additional shares of Common Stock and/or to decide the appropriate form of distribution to be made pursuant to this paragraph (iii) and to determine the value thereof. In the event of any
such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended. 
  

 22 

 Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is
made as provided in Section 11 or Section 13 hereof, the Company shall (a) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment, promptly file with the Rights
Agent, and with the transfer agent for the Common Stock, a copy of such certificate, and (c) 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. 
 Section 13. Consolidation, Merger or Sale or Transfer
of Assets 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 or earning power aggregating
50% or more of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any Person or Persons (other than the Company or any Subsidiary of the Company in one or more transactions each of which complies with
Section 11(o) hereof), then, and in each such case, proper provisions 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,
in accordance with the terms of this Rights Plan, such number of duly and validly authorized and issued, fully paid, nonassessable and freely tradeable shares of Common Stock of the Principal Party (as such term is hereinafter defined), not subject
to any liens, encumbrances, rights of first refusal or other adverse claims, as shall be equal to the result obtained by (1) multiplying the then current Purchase Price by the number of one two-thousandths of a Preferred Share for which a Right
is exercisable immediately prior to the first occurrence of a Section 13 Event, and dividing that product (which product, following the first occurrence of a Section 13 Event, shall be the aggregate “Purchase Price” for all the
securities that may be purchased pursuant to the Right upon the adjustment pursuant to this clause (i) and for all purposes of this Rights Plan) by (2) 50% of the current market price (determined pursuant to Section 11(d) hereof) per
share of the Common Stock of such Principal Party on the date of consummation of such Section 13 Event; (ii) such Principal Party (i.e., the issuer of such shares) shall thereafter be liable for, and shall assume, by virtue of such
Section 13 Event, all the obligations and duties of the Company pursuant to this Rights Plan; (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, but not limited to, the reservation of a
sufficient number of shares of its Common Stock in accordance with the provisions of this Rights Plan) in connection with the consummation of any such transaction as may be necessary to assure that the provisions hereof shall thereafter be 

  

 23 

 
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), 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), the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions; provided, however, that in any such case, (1) if the
Common Stock of such Person is not at such time and has not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, and such Person is a direct or indirect Subsidiary of another Person
the Common Stock of which is and has been so registered, “Principal Party” shall refer to such other Person; and (2) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Stocks of two or
more of which are and have been so registered, “Principal Party” shall refer to whichever of such Persons is the issuer of the Common Stock having the greatest aggregate market value. 
 (c) The Company shall not consummate any such consolidation, merger, sale or transfer (or any other transaction constituting a Section 13 Event)
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 (or any other transaction constituting a Section 13 Event), 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; and 
 (ii) 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 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). The 

  

 24 

 
Company shall not enter into any transaction of the kind referred to in this Section 13 if at the time of such transaction there are any rights,
warrants, instruments or securities outstanding or any agreements or arrangements which, as a result of the consummation of such transaction, would eliminate or substantially diminish the benefits intended to be afforded by the Rights. 

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, there shall be paid to the registered holders of the Rights Certificates with regard to which such fractional Rights would be otherwise issuable, an amount in cash equal to the same fraction of the current
market value of a whole Right. For purposes of this Section 14(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have
been otherwise issuable. The closing price of the Rights for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, 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 of Directors of the Company. 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 of Directors of the Company shall be used. 
 (b) The Company shall not be required to issue fractions of Preferred Shares (other than integral multiples of one two-thousandths of a Preferred Share)
or fractions of shares of Common Stock or other securities upon exercise or exchange of the Rights or to distribute certificates which evidence such fractional shares. In lieu of fractional shares of Common Stock or Preferred Shares, the Company may
pay to the registered holders of Rights Certificates at the time such Rights are exercised or exchanged as herein provided an amount in cash equal to (A) in the case of fractional Common Stock, the same fraction of the current market value of a
share of Common Stock and (B) in the case of a fractional portion of a Preferred Share, the same fraction of the current market value of one Preferred Share. For purposes of this Section 14(b), the current market value of a share shall be
the closing price of such share (as determined pursuant to Section 11(d) hereof) for the Trading Day immediately prior to the date of such exercise. 
 (c) The holder of a Right, by the acceptance of the Right, expressly waives such holder’s right to receive any fractional Rights or any fractional shares upon exercise or exchange of a Right, except as permitted
by this Section 14. 
  

 25 

 Section 15. Rights of Action. All rights of action in respect of this Rights Plan are vested in
the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common Stock); and any registered holder of any Rights Certificate (or, prior to the Distribution Date, of the Common
Stock), without the consent of the Rights Agent or of the holder of any other Rights Certificate (or, prior to the Distribution Date, of the Common Stock), may, in his own behalf and for his own benefit, enforce, and may institute and maintain any
suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Rights Certificate and in this Rights Plan. Without limiting the foregoing or any remedies available to the
holders of the Rights, it is specifically acknowledged that the holders of the Rights would not have an adequate remedy at law for any breach of this Agreement, and shall be entitled to specific performance of the obligations under, and injunctive
relief against actual or threatened violations of the obligations of any Person subject to, this Agreement. 
 Section 16. Agreement of
Rights Holders. Every holder of a Right by acceptance of 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 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 principal
office or offices of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates fully executed; 
 (c) subject to Section 6(a) and Section 7(f) hereof, the Company and the Rights Agent may deem and treat the person in whose name a Rights
Certificate (or, prior to the Distribution Date, the associated Common Stock certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Rights
Certificates or the associated Common Stock certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent, subject to the second sentence of Section 7(e) hereof,
shall be required to be affected by any notice to the contrary; and 
 (d) notwithstanding anything in this Rights Plan to the contrary,
neither the Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Rights Plan by reason of any preliminary or permanent injunction or
other order, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental
authority, prohibiting or otherwise restraining performance of such obligations. 
 Section 17. Rights Certificate Holder Not Deemed a
Shareholder. No holder of any Rights Certificate, as such, shall be entitled to vote (or consent with respect to), receive dividends or be deemed for any purpose whatsoever the holder of any Preferred Shares (or any portion thereof) or shares of
Common Stock or of any other securities of the Company which 
  

 26 

 
may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed
to confer upon the holder of any Rights Certificate, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings, proceedings or other actions affecting shareholders (except as provided in Section 24 hereof), or to receive dividends or subscription rights, or otherwise, until the
Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof. 
 Section 18.
Concerning the Rights Agent. 
 (a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by
it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and disbursements and other disbursements incurred in the administration and execution of this Rights Plan and the exercise and performance
of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent,
for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Rights Plan. 
 (b) The Rights
Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Rights Plan in reliance upon any Rights Certificate or certificate for Common Stock
or for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons. 
 Section 19. Merger or Consolidation
or Change of Name of Rights Agent. 
 (a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or with
which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding to the corporate trust business of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent under this Rights Plan without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided, however, that such corporation would
be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Rights Plan any of the Rights Certificates shall have
been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall
not have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have the full
force provided in the Rights Certificates and in this Rights Plan. 
  

 27 

 (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 Rights Plan. 
 Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties and obligations imposed by this Rights
Plan upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound: 
 (a) The Rights Agent may consult with legal counsel acceptable to the Company (who may be legal counsel for the Company), and the opinion of such counsel shall be full and complete authorization and protection to the
Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion. 
 (b) Whenever in the performance of
its duties under this Rights Plan the Rights Agent shall deem it necessary or desirable that any fact or matter (including, without limitation, the identity of any Acquiring Person and the determination of “current market price”) be proved
or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a
certificate signed by the Chairman of the Board, the President, any Vice President, the Treasurer or the Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights Agent for any action
taken or suffered in good faith by it under the provisions of this Rights Plan in reliance upon such certificate. 
 (c) The Rights Agent
shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct. 
 (d) The Rights Agent shall not be under any
responsibility in respect of the validity of this Rights Plan or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Rights Certificate (except its
countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Rights Plan or in any Rights Certificate; nor shall it be responsible for any adjustment required under the
provisions of Section 11 or Section 13 hereof or responsible for the manner, method or amount of any such adjustment (except with respect to the exercise of Rights evidenced by Rights Certificates after actual notice of any such
adjustment); 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 to be issued pursuant to this Rights Plan or any Rights Certificate or as to whether
any shares of Common Stock will, when so issued, be validly authorized and issued, fully paid and nonassessable. 
 (e) The Company agrees
that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out
or performing by the Rights Agent of the provisions of this Rights Plan. 
  

 28 

 (f) The Rights Agent is hereby authorized and directed to accept instructions with respect to the
performance of its duties hereunder from the Chairman of the Board, the President, any Vice President, the Secretary or the Treasurer of the Company, and to apply to such officers for advice or instructions in connection with its duties, and it
shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer. 
 (g) The Rights Agent and any shareholder, director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the
Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Rights Agent under this Rights Plan. Nothing herein shall preclude the Rights Agent from acting in any other capacity
for the Company or for any other legal entity. 
 (h) The Rights Agent may execute and exercise any of the rights or powers hereby vested in
it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the
Company resulting from any such act, default, neglect or misconduct; provided, however, reasonable care was exercised in the selection and continued employment thereof. 
 (i) No provision of this Rights Plan shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of
its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it. 
 (j) 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 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. 
 Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this Rights Plan upon sixty (60) days’ notice in writing mailed to the Company, and to each transfer agent of the Common Stock or Preferred Shares, by registered or
certified mail, and to the holders of the Rights Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon thirty (30) days’ notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to the transfer agent of the Common Stock or Preferred Shares, by registered or certified mail, and to the 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 have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination, and the Company shall be

  

 29 

 
responsible for sending any required notice. 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 sixty (60) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then any registered holder of any Rights Certificate may apply to any court
of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United States or of any
state of the United States, in good standing, which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights
Agent a combined capital and surplus, along with its Affiliates, of at least $50,000,000. 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 and records at the time held by it hereunder, and execute and deliver any further assurance, conveyance,
act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock and Preferred Shares and
mail a notice thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be. 
 Section 22. Issuance of New Rights
Certificates. Notwithstanding any of the provisions of this Rights Plan or of the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by its Board of Directors
to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other securities or property purchasable under the Rights Certificates made in accordance with the provisions of this Rights Plan. In addition, in
connection with the issuance or sale of shares of Common Stock following the Distribution Date and prior to the redemption 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 plan or arrangement, or upon the exercise, conversion or exchange of securities hereinafter issued by the Company, and (b) may, in any other case, if deemed necessary or appropriate by the
Board of Directors of the Company, issue Rights Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Rights Certificate shall be issued if, and to the extent
that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Rights Certificate would be issued, and (ii) no such Rights
Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof. 
  

 30 

 Section 23. Redemption and Termination. 
 (a) The Board of Directors of the Company may, at its option, as approved by a Majority Director Vote, at any time prior to the earlier of (i) the
time that any Person becomes an Acquiring Person, or (ii) the Final Expiration Date, redeem all but not less than all of the then outstanding Rights at a redemption price of $.0025 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”). The redemption of the Rights pursuant to this
Section 23(a) may be made effective at such time, on such basis and with such conditions as the Board of Directors of the Company, in its sole discretion, may establish (as approved by a Majority Director Vote). 
 (b) Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price for each Right so held. Promptly
after the action of the Board of Directors ordering the redemption of the Rights, the Company shall give notice of such redemption to the Rights Agent and the 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; provided, however, that the failure to give, or any defect in,
any such notice shall not affect the validity of such redemption. 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. Neither the Company nor any of its Affiliates or Associates may redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this
Section 23 or in Section 11(r) hereof, and other than in connection with the purchase of shares of Common Stock prior to the Distribution Date. 
 Section 24. 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 Common Stock or to make any other distribution to the holders of Common 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 Common Stock rights or warrants to subscribe for or to purchase any additional shares of Common Stock or shares of stock of any class or any other securities, rights or options, or
(iii) to effect any reclassification of its Common Stock (other than a reclassification involving only the subdivision of outstanding shares of Common 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 50% or more of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Rights Certificate, to the
extent feasible and in accordance with Section 25 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 

  

 31 

 
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 Common Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least twenty (20) days prior to the record date
for determining holders of the shares of Common Stock for purposes of such action, and in the case of any such other action, at least twenty (20) days prior to the date of the taking of such proposed action or the date of participation therein
by the holders of the shares of Common 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 each holder of a Rights Certificate, to the extent feasible and in accordance with Section 25 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 Common Stock shall be deemed
thereafter to refer, if appropriate, to other securities. 
 (c) The failure to give notice required by this Section 24 or any defect
therein shall not affect the legality or validity of the action taken by the Company or the vote on any such action. 
 Section 25.

 Section 26. Supplements and Amendments. The Company may, and the Rights Agent shall if the Company
so directs, from time to time, supplement or amend this Agreement without the approval of any holder(s) of Rights Certificates in order to cure any ambiguity, to correct or supplement any provision contained herein which may be defective or
inconsistent with any other provisions herein, or to make, change or effect any other provisions with respect to the Rights which the Company may deem necessary or desirable, any such supplement or amendment to be approved by a Majority Director
Vote and evidenced by a writing signed by the Company and the Rights Agent; provided, however, that, from and after such time as any Person becomes an Acquiring Person, this Agreement shall not be amended in any manner which would adversely affect
the interests of the holders of Rights. Without limiting the foregoing, the Company may, at any time prior to such time as any Person becomes an Acquiring Person, amend this Agreement to lower the percentage thresholds set forth in Sections 1(a) and
3(a) hereof to not less than the greater of (a) the sum of .001% and the largest percentage of the outstanding shares of Common Stock then known by the Company to be beneficially owned by any Person (other than the Company, any Subsidiary of
the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any entity holding shares of Common Stock for or pursuant to the terms of any such plan) and (b) 10.0%. Upon the delivery of a certificate from an
appropriate officer of the Company which states that the proposed supplement or amendment is in compliance with the terms of this Section 26, the Rights Agent shall execute such supplement or amendment. Notwithstanding anything contained in
this Rights Plan to the contrary, no supplement or amendment may be made after the time that any Person becomes an Acquiring Person unless such supplement or amendment (i) does not adversely affect the interests of the holders of Rights, and
(ii) is approved by a Majority Director Vote. 
 Section 27. Successors. All the covenants and provisions of this Rights Plan 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 28. Determinations and Actions by the Board of Directors, etc. For all purposes of this Rights Plan, any calculation of the number of shares of Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common Stock of which any Person is the Beneficial Owner, shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the
Exchange Act. The Board of Directors of the Company (where specifically provided for herein, by the requisite vote and/or with the approval of Independent Directors (where a Majority Director Vote is required)) shall have the exclusive power and
authority to administer this Rights Plan and to exercise all rights and powers specifically granted to the Board (with, where specifically provided for herein, the approval of Independent Directors (where a Majority Director Vote is required)) or to
the Company, or as may be necessary or advisable in the administration of this Rights Plan, including, without limitation, the right and power to (i) interpret the provisions of this Rights Plan and (ii) make all determinations deemed
necessary or advisable for the administration of this Rights Plan (including a determination to redeem or not redeem the Rights, to exchange the Rights or to amend or supplement this Rights Plan). All such actions, calculations, interpretations and
determinations (including, for purposes 
  

 33 

 
of clause (y) below, all omissions with respect to the foregoing) which are done or made by the Board (with, where specifically provided for herein, the
approval of Independent Directors (where a Majority Director Vote is required)) in good faith, shall (x) be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights and all other parties and (y) not subject
the Board or the Independent Directors (if applicable) to any liability to the holders of the Rights. 
 The Board may at any time and from
time to time (and upon the occurrence of a Triggering Event shall forthwith) establish and set aside one or more funds (in such amount or amounts as the Board shall deem necessary or desirable), whether in trust, escrow or other segregated accounts
(regardless of whether any such fund is combined for administrative purposes with any other fund or funds established by the Company, for the purpose of assuring that adequate resources are available to the Board of Directors (or Independent
Directors, as the case may be), to enable them to carry out their prescribed functions, and to maintain their authority and powers, under this Agreement, or to fulfill their fiduciary obligations to the shareholders of the Company. Without limiting
the generality of the statement of purposes contained in the next preceding sentence, the fund or funds so established shall, on demand of a majority of the Independent Directors, be made available to the Independent Directors for the purposes of
(i) seeking affirmatively to establish, or to defend, the validity of this Agreement, including, without limitation, this Section 28, and (ii) seeking affirmatively to establish, or to defend, the validity and/or propriety of any
action taken (or omitted to be taken) by the Independent Directors pursuant to this Agreement, the Articles of Incorporation or the Bylaws or applicable provisions of the Florida Business Corporation Act. The establishment by the Board, and
utilization by the Board of Directors (or Independent Directors, as the case may be), of any fund or funds established pursuant to this paragraph shall be separate and apart from, and shall not detract from, diminish or otherwise affect adversely,
any rights or protections afforded, conferred or given to the Company’s Directors (including the Independent Directors) pursuant to the Articles of Incorporation or Bylaws of the Company. 
 Section 29. Benefits of this Rights Plan. 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, the registered holders of the Common Stock). 
 Section 30. 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. Without limiting the
foregoing, if any provision requiring that a determination, vote or approval be made by less than the entire Board (or at a time or with the concurrence of a group of directors consisting of less than the entire Board) is held by a court of
competent jurisdiction or other authority to be invalid, void or unenforceable, such determination, vote or approval shall then be made by the full Board of Directors in accordance with applicable law and the Company’s Articles of Incorporation
and By-laws. 
  

 34 

 Section 31. 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 Florida 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; except that the rights, duties and obligations of the Rights Agent shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts. 
 Section 32. Consent to Jurisdiction; Service of Process. The Company, the Rights Agent and the holders of the Rights Certificates hereby
irrevocably submit to the jurisdiction of the state or federal courts located in Broward County, Florida in connection with any suit, action or other proceeding arising out of or relating to this Rights Plan and the transactions contemplated hereby,
and hereby agree not to assert, by way of motion, as a defense, or otherwise in any such suit, action or proceeding that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper
or that this Rights Plan or the subject matter hereof may not be enforced by such courts. 
 Section 33. Counterparts. This Agreement
may be executed in counterparts and both of such counterparts shall for all purposes be deemed to be an original, and such counterparts shall together constitute but one and the same instrument. 
 Section 34. Descriptive Headings. Descriptive headings of the several Sections of this Rights Plan are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof. 
 Section 35. Consequential Damages. Neither party to
this Agreement shall be liable to the other party or any third party for consequential damages. 
 Section 36. 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.

 EXHIBIT A 
 FORM 
 of 
 ARTICLES OF AMENDMENT 
 DESIGNATING 
 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK 
 of 
 MEDNAX, INC. 
 (Pursuant to
Section 607.0602 of the 
 Florida Business Corporation Act) 
 Mednax, Inc., a corporation organized and existing under the Florida Business Corporation Act (hereinafter called the “Corporation”), hereby
adopts the following amendments to its Articles of Incorporation, which were approved, without the requirement of shareholder action, by resolution adopted by the Board of Directors of the Corporation as required by Section 607.0602 of the
Florida Business Corporation Act by unanimous written consent in lieu of a meeting dated December __, 2008. 
 Pursuant to the authority
granted to and vested in the Board of Directors of this Corporation (hereinafter called the “Board of Directors” or the “Board”) in accordance with the provisions of the Corporation’s Articles of Incorporation, the
Corporation hereby creates a series of Preferred Stock, par value $0.01 per share, of the Corporation (the “Preferred Stock”), and hereby states the designation and number of shares, and fixes the relative rights, preferences, and
limitations thereof as follows: 
 Series A Junior Participating Preferred Stock: 
 Section 1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Stock”
(the “Series A Preferred Stock”) and the number of shares constituting the Series A Preferred Stock shall be fifty thousand (50,000). Such number of shares may be increased or decreased by resolution of the Board of Directors; provided,
that no decrease shall reduce the number of shares of Series A Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, rights or warrants
or upon the conversion of any outstanding securities issued by the Corporation convertible into Series A Preferred Stock. 
 Section 2.
Dividends and Distributions. 
 (A) Subject to the rights of the holders of any shares of any series of Preferred Stock (or any
similar stock) ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred Stock, in preference to the holders of Common Stock, par value $.01 per share (the “Common
Stock”), of the Corporation, and of any 

  

 A-1 

 
other junior 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 first 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 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, 2,000 times the aggregate per share amount of all cash dividends, and 2,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions, other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock since the immediately preceding Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series A Preferred Stock. In the event the Corporation shall at any time declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision
or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case
the amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 
 (B) The Corporation shall declare a dividend or distribution on the Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); 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 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 Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the
date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The
Board of Directors may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be not more than 60 days prior to the
date fixed for the payment thereof. 
  

 A-2 

 Section 3. Voting Rights. The holders of shares of Series A Preferred Stock shall have the
following voting rights: 
 (A) Subject to the provision for adjustment hereinafter set forth, each share of Series A Preferred Stock shall
entitle the holder thereof to 2,000 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time declare or pay any dividend on the Common Stock payable in shares of Common Stock, or
effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the number of votes per share to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 
 (B) Except as otherwise provided herein, in any other Articles of Designations creating a series of Preferred Stock or any similar stock, or by law, the
holders of shares of Series A Preferred Stock and the holders of shares of Common Stock and any other capital stock of the Corporation having general voting rights shall vote together as one class on all matters submitted to a vote of stockholders
of the Corporation. 
 (C) Except as set forth herein, or as otherwise provided by law, holders of Series A Preferred Stock shall have no
special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action. 
 Section 4. Certain Restrictions. 
 (A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or
not declared, on shares of Series A Preferred Stock outstanding shall have been paid in full, the Corporation shall not: 
  

	 	(i)	declare or pay dividends, or make any other distributions, on any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the
Series A Preferred Stock; 

  

	 	(ii)	declare or pay dividends, or make any other distributions, on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with
the Series A Preferred Stock, except dividends paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then
entitled; 

  

 A-3 

	 	(iii)	redeem or purchase or otherwise acquire for consideration shares of any stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such junior stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution,
liquidation or winding up) to the Series A Preferred Stock; or 

  

	 	(iv)	redeem or purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A Preferred Stock,
except in accordance with a purchase offer made in writing or by publication (as determined by the Board 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 Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the
acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock subject to the conditions and restrictions on issuance set
forth herein, in the Articles of Incorporation, or in any other Articles of Designations creating a series of Preferred Stock or any similar stock or as otherwise required by law. 
 Section 6. Liquidation, Dissolution or Winding Up. Upon any liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall
have received $1.00 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, and further provided that the holders of shares of Series A Preferred Stock shall be
entitled to receive an aggregate amount per share, subject to the provision for adjustment hereinafter set forth, equal to 2,000 times the aggregate amount to be distributed per share to holders of shares of Common Stock, or (2) to the holders
of shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except distributions made ratably on the Series A Preferred Stock and all such parity stock in
proportion to the total amounts to which the holders of all such shares are entitled upon such liquidation, dissolution or winding up. In the event the Corporation shall at any time declare or pay any dividend on the Common Stock payable in shares
of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares
of Common Stock, then in each such case the aggregate amount to which holders of shares of 

  

 A-4 

 
Series A Preferred Stock were entitled immediately prior to such event under the proviso in clause (1) 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. 
 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 each share of Series A Preferred Stock shall at the same
time be similarly exchanged or changed into an amount per share, subject to the provision for adjustment hereinafter set forth, equal to 2,000 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the
case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the
amount set forth in the preceding sentence with respect to the exchange or change of shares of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 
 Section 8. No Redemption. The shares of Series A Preferred Stock shall not be redeemable. 
 Section 9. Rank. The Series A Preferred Stock shall rank, with respect to the payment of dividends and the distribution of assets, junior to all series of any other class of the Corporation’s Preferred Stock. 
 Section 10. Amendment. The Articles of Incorporation of the Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock so as to affect them adversely without the affirmative vote of the holders of at least two-thirds of the outstanding shares of Series A Preferred Stock, voting together
as a single class. At any time when there are no shares of Series A Preferred Stock outstanding, the number, designation, preferences and rights of the Series A Preferred Stock as set forth in these Articles of Designations may be amended by the
Board of Directors in the manner provided in Section 607.0602 and as otherwise permitted under the Florida Business Corporation Act. 
 Section 11. Fractional Shares. The holder of any fractional share of Series A Preferred Stock issued by the Corporation shall have the proportional rights of a holder of a share of Series A Preferred Stock to the extent of the
fractional amount issued. For example, a holder of one two-thousandth of a share of Series A Preferred Stock would have one two-thousandth of the rights of a holder of one share of the Series A Preferred Stock (e.g., the holder of one two-thousandth
of a share would have one vote on matters subject to a vote of holders of the Series A Preferred Stock, as compared to a whole share which has 2,000 votes).

 RIGHTS CERTIFICATE 
 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 Preferred Share Purchase Rights Plan, dated as of December __, 2008 (the “Rights
Plan”), between Mednax, Inc., a Florida corporation (the “Company”), and Computershare Trust Company, N.A. (the “Rights Agent”), to purchase from the Company at any time prior to 5:00 P.M. (Eastern time) on March 31,
2009 at the office or offices of the Rights Agent designated for such purpose, or its successor(s) as Rights Agent, one two-thousandth of a fully paid, non-assessable share of the Company’s Series A Junior Participating Preferred Stock, par
value $0.01 per share (the “Preferred Shares”) (or in certain circumstances, cash, property or other securities), at a purchase price of $75.00 per one two-thousandth of a Preferred 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 Purchase Price shall be paid in cash. 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 __, 2008, based on the Company’s Common Stock and Preferred Shares as constituted at
such date. 
 Upon the occurrence of a Section 11(a)(ii) Event (as such term is defined in the Rights Plan), if the Rights evidenced by
this Rights Certificate are beneficially owned by (i) an Acquiring Person or an Affiliate or Associate thereof (as such terms are defined in the Rights Plan), or (ii) an Acquiring Person Transferee (as such term is defined in the Rights
Plan), such Rights 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 Plan, the Purchase Price and the number and kind of shares of the Company’s capital 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 (as such term is defined in the Rights Plan). 
 This Rights Certificate, and the Rights evidenced hereby, are subject to all of the terms, provisions and conditions of the Rights Plan, which terms,
provisions and conditions are hereby incorporated herein by reference and made a part hereof and to which Rights Plan reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder
and thereunder of the Rights Agent, the Company and the holders of the Rights Certificates, which limitations of rights include (without limitation) the temporary suspension of the exercisability of such Rights under the specific circumstances set
forth in the Rights Plan. In the event of any conflict or inconsistency between the terms, provisions and conditions of Rights as set forth in the Rights Plan and those described or set forth in this Rights Certificate, the terms, provisions and
conditions set forth in the Rights Plan shall govern and prevail. Copies of the Rights Plan are on file at the above-mentioned office of the Rights Agent and are also available upon written request to the Rights Agent. 
  

 B-2 

 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. This Rights Certificate, with or without other Rights Certificates, upon surrender at the principal office or offices of the Rights
Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing Rights entitling the holder to purchase a like aggregate number of Preferred Shares as the Rights evidenced
by the Rights Certificate or Rights Certificates surrendered shall have entitled such holder to purchase. 
 Subject to the terms, provisions
and conditions of the Rights Plan, the Rights evidenced by this Certificate (i) may be redeemed by the Company at its option at a redemption price of $.0025 per Right or (ii) may be exchanged in whole or in part for shares of Common Stock.
Under certain circumstances set forth in the Rights Plan, the decision to redeem shall require the concurrence of a majority of the members of the full Board of Directors and a majority of any Independent Directors (as such term is defined in the
Rights Plan). The Rights Plan is also subject to amendment and supplement by the Company, on the terms and conditions set forth in the Rights Plan. 
 No fractional shares of Common Stock or Preferred Shares (other than integral multiples of one two-thousandth of a Preferred Share) will be issued upon the exercise of any Right or Rights evidenced hereby, but in lieu thereof a cash payment
will be made, as provided in the Rights Plan. 
 No holder of this Rights Certificate shall be entitled to vote (or consent with respect to)
or receive dividends or be deemed for any purpose the holder of any Preferred Shares or shares of Common 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 Plan or herein be construed to confer upon the holder hereof, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting or
proceeding thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in the Rights Plan), 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 Plan. 
 This
Rights Certificate shall not be valid or obligatory for any purpose until it shall have been countersigned by the Rights Agent.

 B-12Assignment and Joinder Agreement, dated as of January 1, 2009

 Exhibit 10.1 
 THIS ASSIGNMENT AND JOINDER AGREEMENT IS NOT SUBJECT TO THE DOCUMENTARY STAMP TAX OF THE STATE OF FLORIDA BECAUSE (1) IT IS NOT SECURED BY A MORTGAGE ON FLORIDA REAL ESTATE; AND (2) IT WAS EXECUTED BY THE
INITIAL BORROWER, THE PERMANENT BORROWER AND THE GUARANTORS IN THE STATE OF VIRGINIA AND DELIVERED TO THE LENDER IN THE STATE OF NORTH CAROLINA, AND THUS WAS EXECUTED AND DELIVERED OUTSIDE OF THE STATE OF FLORIDA. SEE RULE 12B-4.053(34) FLORIDA
ADMINISTRATIVE CODE. 
 ASSIGNMENT AND JOINDER AGREEMENT 
 THIS ASSIGNMENT AND JOINDER AGREEMENT (this “Agreement”), dated as of January 1, 2009, is by and among Mednax, Inc., a Florida
corporation (the “Permanent Borrower”), Mednax Services, Inc. (formerly known as Pediatrix Medical Group, Inc.), a Florida corporation (the “Initial Borrower”), the Guarantors identified on the signature pages
hereto and Wachovia Bank, National Association, in its capacity as administrative agent (in such capacity, the “Administrative Agent”) under that certain Credit Agreement, dated as of September 3, 2008 (as amended, modified,
extended, restated, replaced, or supplemented from time to time, the “Credit Agreement”), by and among the Initial Borrower, the Guarantors identified therein (the “Guarantors”), the Lenders identified therein and
the Administrative Agent. Capitalized terms used herein but not otherwise defined shall have the meanings provided in the Credit Agreement. 
 The Initial Borrower is exercising its option under Section 9.6(g) of the Credit Agreement to assign all of its rights and obligations under the Credit Agreement to the Permanent Borrower (the “Assignment”) effective
as of the date hereof. In connection with the Assignment, the Permanent Borrower is required to become the “Borrower” under the Credit Agreement, and the Initial Borrower is required to become a “Guarantor” under the Credit
Agreement. 
 Accordingly, the Permanent Borrower and the Initial Borrower hereby agree as follows with the Administrative Agent, for the
benefit of the Lenders: 
 1. The Permanent Borrower hereby acknowledges, agrees and confirms that, by its execution of this Agreement, the
Permanent Borrower (a) assumes the rights and obligations of the Initial Borrower as Borrower under the Credit Agreement and (b) agrees to become the Borrower under the Credit Agreement and shall have all of the obligations of the Borrower
thereunder as if it had executed the Credit Agreement. The Permanent Borrower hereby ratifies, as of the date hereof, and agrees to be bound by, all of the terms, provisions and conditions contained in the applicable Credit Documents, including,
without limitation (a) all of the representations and warranties set forth in Article III of the Credit Agreement, (b) all of the affirmative and negative covenants set forth in Articles V and VI of the Credit Agreement and
(c) the expense and indemnification provisions set forth in Section 9.5 of the Credit Agreement. Without limiting the generality of the foregoing terms of this Paragraph 1, the Permanent Borrower hereby assumes and agrees punctually
to pay, perform and discharge when due each of the Credit Party Obligations and each and every debt, covenant and agreement incurred, made or to be paid, performed or discharged by the Borrower under the Credit Documents. 

 2. The Initial Borrower hereby (a) assigns its rights and obligations as Borrower under the Credit
Agreement to the Permanent Borrower and (b) acknowledges, agrees and confirms that, by its execution of this Agreement, the Initial Borrower will remain a party to the Credit Agreement as a “Guarantor” thereunder and shall have all of
the obligations of a Guarantor thereunder as if it had executed the Credit Agreement as such. The Initial Borrower hereby ratifies, as of the date hereof, and agrees to be bound by, all of the terms, provisions and conditions contained in the
applicable Credit Documents, including, without limitation (a) all of the representations and warranties set forth in Article III of the Credit Agreement and (b) all of the affirmative and negative covenants set forth in
Articles V and VI of the Credit Agreement. Without limiting the generality of the foregoing terms of this Paragraph 1, the Initial Borrower hereby guarantees, jointly and severally together with the other Guarantors, the prompt payment of
the Credit Party Obligations in accordance with Article X of the Credit Agreement. 
 3. Upon the effectiveness of the assumptions
provided for in this Agreement, (a) the Permanent Borrower will be the “Borrower” for all purposes of the Credit Agreement and the other Credit Documents and shall be subject to each and every Obligation, debt, covenant and agreement
incurred, made or to be paid, performed or discharged by the Borrower thereunder and shall exercise every right and power of the Borrower under the Credit Agreement and the other Credit Documents with the same force and effect as if the Permanent
Borrower were the original Borrower thereunder and (b) the Initial Borrower will be a “Guarantor” for all purposes of the Credit Agreement and the other Credit Documents and shall be subject to each and every Obligation, debt,
covenant and agreement incurred, made or to be paid, performed or discharged by a Guarantor thereunder and shall exercise every right and power of a Guarantor under the Credit Agreement and the other Credit Documents with the same force and effect
as if the Initial Borrower were an original Guarantor thereunder. 
 4. The Permanent Borrower acknowledges and confirms that it has received
a copy of the Credit Agreement and the schedules and exhibits thereto. The information on the schedules to the Credit Agreement are hereby supplemented (to the extent permitted under the Credit Agreement) to reflect the information shown on the
attached Schedule A. 
 5. Each of the parties hereto certifies that the information on Schedule B to this Agreement is
true and correct as of the date hereof. 
 6. The Initial Borrower and the Guarantors confirm that the Credit Agreement is, and upon the
Permanent Borrower becoming the Borrower, shall continue to be, in full force and effect. The parties hereto confirm and agree that immediately upon the Permanent Borrower becoming the Borrower the term “Credit Party Obligations,” as used
in the Credit Agreement, shall include all obligations of the Permanent Borrower under the Credit Agreement and under each other Credit Document. 

 7. Each of the Permanent Borrower and the Initial Borrower agrees that, after giving effect to this
Agreement, the Permanent Borrower shall own directly or indirectly 100% of the Equity Interests of the Initial Borrower. 
 8. Each of the
Permanent Borrower, the Initial Borrower and the Guarantors agree that at any time and from time to time, upon the written request of the Administrative Agent, it will execute and deliver such further documents and do such further acts as the
Administrative Agent may reasonably request in accordance with the terms and conditions of the Credit Agreement in order to effect the purposes of this Agreement. 
 9. This Agreement (a) may be executed in two or more counterparts, each of which shall constitute an original but all of which when taken together shall constitute one contract and (b) may, upon execution,
be delivered by facsimile or electronic mail, which shall be deemed for all purposes to be an original signature. 
 10. This Agreement shall
be governed by and construed and enforced in accordance with the laws of the State of New York. The terms of Sections 9.13 and 9.16 of the Credit Agreement are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to
such terms. 
 [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK] 

 IN WITNESS WHEREOF, each of the Initial Borrower and the Permanent Borrower has caused this Agreement to
be duly executed by its authorized officer, and the Administrative Agent, for the benefit of the Lenders, has caused the same to be accepted by its authorized officer, effective as of the day and year first above written.
