Amendment No. 1 to Rock-Tenn Company Annual Excecutive Bonus Program

 Exhibit 10.1 
 AMENDMENT NUMBER 1 TO 
 ROCK-TENN COMPANY 
 ANNUAL EXECUTIVE BONUS PROGRAM 
 Rock-Tenn Company hereby amends § 5 of the Rock-Tenn Company Annual Executive Bonus Program to read as
follows: 
 CERTIFICATION 
 The Committee at the end
of each Fiscal Year shall certify the extent, if any, to which the Performance Goals set for each Participant for such Fiscal Year have been met and shall determine the bonus payable to each Participant based on the extent, if any, to which he or
she met his or her Performance Goals. However, the Committee shall have the right to reduce the bonus determined under this § 5 to the extent that the Committee acting in its discretion determines that the Performance Goals set for a
Participant for a Fiscal Year no longer were appropriate for such Participant at the end of such Fiscal Year. If the Committee certifies that a bonus is payable to a Participant for any Fiscal Year, such bonus shall be paid in cash as soon as
practical after such certification has been made, but in any event, by no later than the 15th day of March following the end of such Fiscal Year. However, no
Participant shall have a right to the payment of a bonus for any Fiscal Year if his or her employment with Rock-Tenn Company has terminated for any reason whatsoever before the date the bonus is actually paid unless the Committee in the exercise of
its absolute discretion affirmatively directs Rock-Tenn Company to pay such bonus to, or on behalf of, such Participant. 
 This Amendment Number 1
shall be effective as of this 30th day of October 2008.

 AMENDED AND RESTATED RIGHTS AGREEMENT 
 This Amended and Restated Rights Agreement (this “Agreement”), dated as of January 30, 2009, between Nanophase Technologies Corporation, a
Delaware corporation (the “Company”), and Mellon Investor Services LLC, a New Jersey limited liability company, as Rights Agent (the “Rights Agent”) amends and restates the Rights Agreement, dated as of October 28, 1998,
between the Company and LaSalle National Bank, as amended (the “Original Agreement”). 
 On October 28, 1998, the Board of
Directors of the Company (the “Board of Directors”) authorized and declared a dividend of one preferred share purchase right (a “Right”) for each Common Share (as hereinafter defined) of the Company outstanding on
November 10, 1998 (the “Record Date”), each Right representing the right to purchase one ten-thousandth of a Preferred Share (as hereinafter defined), upon the terms and subject to the conditions herein set forth, and further
authorized and directed the issuance of one Right with respect to each Common Share that shall become outstanding between the Record Date and the earliest of the Distribution Date, the Redemption Date and the Final Expiration Date (as such terms are
hereinafter defined). 
 The Company and the Rights Agent may from time to time supplement or amend the Original Agreement in accordance with
the provisions of Section 27 of the Original Agreement. 
 The Board of Directors has determined that the amendment and restatement of
the Original Agreement as set forth herein is desirable and in the best interest of the Company and its shareholders. 
 Accordingly, in
consideration of the premises and the mutual agreements herein set forth, the parties hereby agree as follows: 
 Section 1. Certain
Definitions. For purposes of this Agreement, the following terms have the meanings indicated: 
 (a) “Acquiring Person” shall
mean any Person (as such term is hereinafter defined) who or which, together with all Affiliates and Associates (as such terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as hereinafter defined) of 35% or more of the
Common Shares of the Company then outstanding, but shall not include (i) the Company, (ii) any Subsidiary (as hereinafter defined) of the Company, (iii) any employee benefit plan of the Company or any Subsidiary of the Company,
(iv) any entity organized, appointed or established by the Company for, or pursuant to the terms of, any such plan, or (v) any Person who, prior to the Company’s public announcement of the Board’s approval of this Agreement, is
the Beneficial Owner of 35% or more of the Common Shares of the Company then outstanding (a “Current 35% Owner”); provided, however, that if following such public announcement of the Board’s approval of this Agreement, such Current
35% Owner becomes the Beneficial Owner of any additional Common Shares of the Company and is the Beneficial Owner of 35% or more of the Common Shares of the Company then outstanding, then such Current 35% Owner shall be deemed an “Acquiring
Person”. Notwithstanding the foregoing, no 

 
Person shall become an “Acquiring Person” as the result of (a) an acquisition of Common Shares by the Company which, by reducing the number of
Common Shares outstanding, increases the proportionate number of Common Shares beneficially owned by such Person to 35% or more of the Common Shares of the Company then outstanding or (b) the acquisition by such Person of newly issued Common
Shares directly from the Company (it being understood that a purchase from an underwriter or other intermediary is not directly from the Company); provided, however, that if a Person becomes the Beneficial Owner of 35% or more of the Common Shares
of the Company then outstanding by reason of share purchases by the Company or the receipt of newly-issued Common Shares directly from the Company and, after such share purchases or direct issuance by the Company, becomes the Beneficial Owner of any
additional Common Shares of the Company and is the Beneficial Owner of 35% or more of the Common Shares of the Company then outstanding, then such Person shall be deemed to be an “Acquiring Person”. Notwithstanding the foregoing, if the
Board of Directors determines in good faith that a Person who would otherwise be an “Acquiring Person”, as defined pursuant to the foregoing provisions of this Section 1(a), has become such inadvertently, and such Person divests as
promptly as practicable a sufficient number of Common Shares so that such Person would no longer be an Acquiring Person, as defined pursuant to the foregoing provisions of this Section 1(a), then such Person shall not be deemed to be an
“Acquiring Person” for any purposes of this Agreement. 
 (b) “Affiliate” and “Associate” shall have the
respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under the Exchange Act (as hereinafter defined) as in effect on the date of this Agreement. 
 (c) 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 (A) the right to acquire (whether such
right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public
offering of securities), or upon the exercise of conversion rights, exchange rights, rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, (x) 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, (y) securities issuable upon
exercise of Rights at any time prior to the occurrence of a Triggering Event (as hereinafter defined) or (z) securities issuable upon exercise of Rights from, and after the occurrence of, a Triggering Event which Rights were acquired by such
Person or any of such Person’s Affiliates or Associates prior to the Distribution Date or pursuant to Section 3(a) or Section 22 hereof (the “Original Rights”) or pursuant to Section 11(i) hereof in connection with an
adjustment made with respect to any Original Rights; or (B) the sole or shared right to vote or dispose pursuant to any agreement, arrangement or understanding; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to
beneficially own, any security if the agreement, arrangement or understanding to vote such security (1) arises 

  

 2 

 
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 or Schedule 13G under the Exchange Act (or any comparable or successor report); or (C) “beneficial
ownership” of (as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Exchange Act); 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 Person’s Affiliates or Associates has any agreement, arrangement or understanding, whether written or
oral (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), for the purpose of acquiring, holding, voting (except to the extent contemplated by the proviso
to Section 1(c)(ii)(B)) or disposing of any securities of the Company. 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. 
 (d) “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking
institutions in Illinois, New York or New Jersey are authorized or obligated by law or executive order to close. 
 (e) “Close of
Business” on any given date shall mean 5:00 P.M., Chicago, Illinois time, on such date; provided, however, that if such date is not a Business Day it shall mean 5:00 P.M., Chicago, Illinois time, on the next succeeding Business Day. 

(f) “Common Shares” shall mean the shares of Common Stock, par value $.01 per share, of the Company, except that when the context refers to
“Common Shares” of any Person other than the Company such term shall mean the capital stock (or equity interest) of such other 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. 
 (g) “Distribution Date” shall have the meaning set forth in Section 3 hereof.

 (h) “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended. 
 (i) “Final Expiration Date” shall have the meaning set forth in Section 7 hereof. 
 (j) “Person” shall mean any individual, trust, firm, corporation, partnership, limited liability company or other entity, and shall include
any successor (by merger or otherwise) of such entity. 
  

 3 

 (k) “Preferred Shares” shall mean shares of Series A Junior Participating Preferred Stock, par
value $.01 per share, of the Company having the rights and preferences set forth in the Form of Certificate of Designations attached to this Agreement as Exhibit A. 
 (l) “Redemption Date” shall have the meaning set forth in Section 7 hereof. 
 (m)
“Section 11(a)(ii) Event” shall mean an event described in Section 11(a)(ii) hereof. 
 (n) “Shares Acquisition
Date” shall mean the first date of public announcement (which for purposes of this definition, shall include, without limitation, a report filed pursuant to Section 13(d) under the Exchange Act) by the Company or an Acquiring Person that
an Acquiring Person has become such. 
 (o) “Subsidiary” of any Person shall mean any corporation or other entity of which a
majority of the voting power of the voting equity securities or equity interest is owned, directly or indirectly, by such Person. 
 (p)
“Triggering Event” shall mean a Section 11(a)(ii) Event (as hereinafter defined) or an event described in Section 13(a) hereof. 
 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 co-Rights Agents as it may deem necessary or desirable. The Rights Agent shall have no duty to
supervise, and in no event shall be liable for, the acts or omissions of any such co-Rights Agent. 
 Section 3. Issuance of Rights
Certificates. 
 (a) Until the earlier of (i) the Close of Business on the tenth day after the Shares Acquisition Date or
(ii) the Close of Business on the tenth Business Day (or such later date as may be determined by action of the Board of Directors 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 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 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 Common Shares aggregating 35% or more of the
then outstanding Common Shares (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 being herein referred to as the “Distribution Date”), (x) the Rights
will be evidenced (subject to the provisions of Section 3(b) 

  

 4 

 
hereof) by the certificates for Common Shares registered in the names of the holders thereof (which certificates shall also be deemed to be certificates for
Rights) and not by separate certificates, (y) the Rights will be transferable only in connection with the transfer of Common Shares and (z) each transfer of Common Shares (including a transfer to the Company) shall constitute a transfer of
the Rights associated with such Common Shares. 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 will, if
requested and provided with all necessary information, send) by first-class, insured, postage-prepaid mail, to each record holder of Common Shares as of the Close of Business on the Distribution Date, at the address of such holder shown on the
records of the Company or the transfer agent or registrar for the Common Shares, a Rights Certificate, in substantially the form of Exhibit B hereto (a “Rights Certificate”), evidencing one Right for each Common Share so held. As of and
after the Distribution Date, the Rights will be evidenced solely by such Rights Certificates. The Company shall promptly notify the Rights Agent in writing upon the occurrence of the Distribution Date and, if such notification is given orally, the
Company shall confirm same in writing on or prior to the Business Day next following. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the Distribution Date has not occurred.

 (b) On the Record Date, or as soon as practicable thereafter, the Company will send a copy of a Summary of Rights to Purchase Preferred
Shares, in substantially the form of Exhibit C hereto (the “Summary of Rights”), by first-class, postage-prepaid mail, to each record holder of Common Shares as of the Close of Business on the Record Date, at the address of such holder
shown on the records of the Company or the transfer agent or registrar for the Common Shares. With respect to certificates for Common Shares outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such
certificates registered in the names of the holders thereof together with a copy of the Summary of Rights attached thereto. Until the Distribution Date (or the earlier of the Redemption Date or the Final Expiration Date), the surrender for transfer
of any certificate for Common Shares outstanding on the Record Date, with or without a copy of the Summary of Rights attached thereto, shall also constitute the transfer of the Rights associated with the Common Shares represented thereby.

 (c) Certificates for Common Shares which become outstanding (including, without limitation, reacquired Common Shares referred to in the
last sentence of this Section 3 (c)) 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 a
legend in substantially the following form: 
 This certificate also evidences and entitles the holder hereof to certain rights as set forth
in a Rights Agreement, as amended, between Nanophase Technologies Corporation and Mellon Investor Services LLC, as Rights Agent, dated as of October 28, 1998 (the “Rights 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 Nanophase Technologies Corporation. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will
no longer be evidenced by this certificate. Nanophase Technologies Corporation will mail to the holder of this certificate a copy of the Rights Agreement, without charge, after receipt of a written request therefor. As described in the Rights
Agreement, Rights issued to any Person who becomes an Acquiring Person or any Associate or Affiliate thereof (as such terms are defined in the Rights Agreement) shall become null and void. 
  

 5 

 With respect to such certificates containing the foregoing legend, until the Distribution Date, the
Rights associated with the Common Shares represented by such certificates shall be evidenced by such certificates alone, and the surrender for transfer of any such certificate shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby. In the event that the Company purchases or acquires any Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such Common Shares shall be deemed cancelled and retired so
that the Company shall not be entitled to exercise any Rights associated with the Common Shares which are no longer outstanding. 
 Section 4. Form of Rights Certificates. 
 (a) The Rights Certificates and the forms of election to purchase and of
assignment to be printed on the reverse thereof, shall be substantially the same as Exhibit B hereto, and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem
appropriate (but which do not affect the rights, duties or responsibilities of the Rights Agent) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the terms, provisions and restrictions elsewhere herein, the Rights
Certificates shall entitle the holders thereof to purchase such number of one ten-thousandths of a Preferred Share as shall be set forth therein at the price per one ten-thousandth of a Preferred Share set forth therein (the “Purchase
Price”), but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price 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 of an Acquiring
Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person became an Acquiring Person, 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 an Acquiring Person and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to
holders of equity interests in such Acquiring Person or to any Person with whom such Acquiring Person has any continuing agreement, arrangement or understanding, whether written or oral, regarding the transferred Rights or (B) a transfer which
the Board of Directors has determined in good faith is part of a plan, arrangement or understanding, whether written or oral, which has as a primary purpose or effect avoidance of the second paragraph of Section 11(a)(ii) 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, and only if the Company
has provided specific written instructions to the Rights Agent) a legend in substantially the following form: 
 The Rights represented by
this Rights Certificate are or were beneficially owned by a Person who was or became an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Rights Agreement). Accordingly, this Rights Certificate
and the Rights represented hereby may become null and void in the circumstances specified in the second paragraph of Section 11(a)(ii) of the Rights Agreement. 
  

 6 

 The provisions of the second paragraph of Section 11(a)(ii) shall apply whether or not any Rights
Certificate actually contains the foregoing legend. 
 Section 5. Countersignature and Registration. The Rights Certificates
shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, any of its Vice Presidents, or its Treasurer, either manually or by facsimile signature, shall have affixed thereto the
Company’s seal or a facsimile thereof, 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 either manually or by facsimile signature
countersigned by the Rights Agent and shall not be valid for any purpose unless countersigned. In case any officer of the Company who shall have signed any of the Rights Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company, such Rights Certificates, nevertheless, may be countersigned by the Rights Agent and issued and delivered by the Company with the same force and effect as though the
Person who signed such Rights Certificates had not ceased to be such officer of the Company; and any Rights Certificate may be signed on behalf of the Company by any Person who, at the actual date of the execution of such Rights Certificate, shall
be a proper officer of the Company to sign such Rights Certificate (as described in the first sentence of this Section 5), although at the date of the execution of this Rights Agreement any such Person was not such an officer. 
 Following the Distribution Date, receipt by the Rights Agent of notice to that effect and all other relevant information referred to in
Section 3(a), the Rights Agent will keep or cause to be kept, at its office designated for such purpose, books for registration and transfer of the Rights Certificates of each series issued hereunder. Such books shall show the names and
addresses of the respective holders of the Rights Certificates, the number of Rights evidenced on its face by each of the Rights Certificates and the date of each of the Rights Certificates. 
 Section 6. Transfer, Split-Up, Combination and Exchange of Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

 (a) Subject to the provisions of Sections 4(b), 14 and 24 hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the earlier of the Redemption Date or the Final Expiration Date, any Rights Certificate or Rights Certificates (other than Rights Certificates representing Rights that have become null and void pursuant to
Section 11(a)(ii) hereof or that have been exchanged pursuant to Section 24 hereof) may be transferred, split-up, combined or exchanged for another Rights Certificate or Rights Certificates, entitling the registered holder to purchase a
like number of one ten-thousandths of a Preferred Share (or Common Shares, other securities or property, as the case may be) as the Rights Certificate or Rights Certificates surrendered then entitle such holder to purchase. Any registered holder
desiring to transfer, split-up, combine or exchange any Rights 

  

 7 

 
Certificate or Rights Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Rights
Certificates to be transferred, split-up, combined or exchanged at the office of the Rights Agent designated for such purpose. The Rights Certificates are transferable only on the registry books of the Rights Agent. 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 or Certificates until the registered holder thereof shall have (i) completed and signed the certificate contained
in the form of assignment set forth on the reverse side of each such Rights Certificate, (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) thereof and of the Rights evidenced thereby and
the Affiliates and Associates thereof as the Company or the Rights Agent shall reasonably request, and (iii) paid a sum sufficient to cover any tax or charge that may be imposed in connection with any transfer, split up, combination or exchange
of the Rights Certificates as required by Section 9 hereof. Thereupon, the Rights Agent shall, subject to Sections 4 and 11(a)(ii) hereof, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as
the case may be, as so requested, registered in such name or names as may be designated by the surrendering registered holder. The Rights Agent shall promptly forward any such sum collected by it to the Company or to such Persons as the Company
shall specify by written notice. The Rights Agent shall have no duty or obligation under any Section of this Agreement which requires the payment of taxes or charges unless and until it is satisfied that all such taxes and/or charges have been paid.

 (b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or
mutilation of a Rights Certificate, and, in case of loss, theft or destruction, of indemnity or security satisfactory to them, and, at the Company’s request, 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 make and deliver a new Rights Certificate of like tenor to the Rights Agent for delivery to the registered holder
in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated. 
 Section 7. Exercise of Rights; Purchase Price;
Expiration Date of Rights. 
 (a) Subject to Section 11(a)(ii) hereof, the registered holder of any valid 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) 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 properly completed and duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose,
together with payment of the Purchase Price (as defined below) for each one ten-thousandth of a Preferred Share (or Common Shares, other securities, cash or property, as the case may be) as to which the Rights are exercised, and an amount equal to
any tax or charge required to be paid under Section 9 hereof, by certified check, cashier’s check, bank draft or money order payable to the order of the Company, at or prior to the earliest of (i) the Close of Business on
October 28, 2011 (the “Final Expiration Date”), (ii) the time at which the Rights are redeemed as provided in Section 23 hereof (the “Redemption Date”), or (iii) the time at which such Rights are exchanged as
provided in Section 24 hereof. Except for those provisions herein which expressly survive the termination of this Agreement, this Agreement shall terminate at such time as the Rights are no longer exercisable hereunder. 
  

 8 

 (b) The Purchase Price for each one ten-thousandth of a Preferred Share to be issued upon exercise of a
Right shall initially be $25.00, shall be subject to adjustment from time to time as provided in Sections 11 and 13 hereof and shall be payable in lawful money of the United States of America in accordance with Section 7(c) below. 

(c) Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to purchase and the certificate on the reverse
side of the Rights Certificate properly completed and duly executed, accompanied by payment of the aggregate Purchase Price for the Preferred Shares (or other securities or property, as the case may be) to be purchased and an amount equal to any
applicable tax or charge required to be paid by the holder of such Rights Certificate in accordance with Section 9 hereof by wire transfer, certified check, cashier’s check, bank draft or money order payable to the order of the Company, or
such other payment method reasonably required by the Company, subject to Section 20(j) hereof, the Rights Agent shall thereupon promptly (i) (A) requisition from any transfer agent of the Preferred Shares (or make available if the
Rights Agent is the transfer agent of the Preferred Shares) certificates for the number of Preferred Shares to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests or (B) requisition
from the depositary agent depositary receipts as provided in Section 14(b) hereof, representing such number of one ten-thousandths of a Preferred Share as are to be purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent with the depositary agent and the Company hereby directs the depositary agent to comply with such request, (ii) when necessary to comply with this Rights Agreement, requisition from the
Company or such other entity the amount of cash to be paid in lieu of issuance of fractional shares in accordance with Section 14 hereof, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to,
or upon the order of, the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, and (iv) when necessary to comply with this Rights Agreement, after receipt, deliver such cash to, or
upon the order of, the registered holder of such Rights Certificate. In the event that the Company elects or is obligated to issue other securities (including Common Shares) of the Company, pay cash and/or distribute other property pursuant to
Section 11(a)(iii) hereof, the Company will make all arrangements necessary so that such other securities, cash and/or property are available for distribution by the Rights Agent, if and when necessary to comply with this Rights Agreement.

 (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 to the registered holder of such Rights Certificate or to his duly authorized assigns, subject to the provisions of Section 14
hereof. 
 (e) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder of Rights or other securities upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered holder shall have (i) properly 

  

 9 

 
completed and duly executed the certificate contained in the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered
for such exercise, and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) thereof and of the Rights evidenced thereby and of the Affiliates or Associates thereof as the Company or the
Rights Agent shall reasonably request. 
 (f) Notwithstanding any statement to the contrary contained in this Agreement or in any Rights
Certificate, if the Distribution Date or the Shares Acquisition Date shall occur prior to the Record Date, the provisions of this Agreement, including (without limitation) Sections 3 and 11(a)(ii), shall be applicable to the Rights upon their
issuance to the same extent such provisions would have been applicable if the Record Date were the date of this Agreement. 
 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 to 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 Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Rights Certificate purchased or acquired by the Company otherwise than upon the exercise
thereof. The Rights Agent shall deliver all cancelled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company. 
 Section 9. Availability of Capital Stock. 
 (a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued Preferred Shares (and,
following the occurrence of a Distribution Date, out of its authorized and unissued Common Shares and/or other securities or out of its authorized and issued shares held in its treasury), the number of Preferred Shares (or Common Shares and/or other
securities, as the case may be) that will be sufficient to permit the exercise in full of all outstanding Rights as provided in this Agreement. 
 (b) The Company covenants and agrees that it will take all such action as may be necessary to ensure that all Preferred Shares (or Common Shares and/or other securities, as the case may be) delivered upon exercise of Rights shall be, at the
time of delivery of the certificates for such Preferred Shares (or Common Shares and/or other securities, as the case may be) (subject to any necessary payment of the Purchase Price), duly and validly authorized and issued and fully paid and
nonassessable shares. 
 (c) 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 or of any Preferred Shares (or Common Shares and/or other securities, as the case may be) upon the exercise of Rights. The Company
shall not, however, be required to pay any transfer tax which may be payable in respect of any transfer or delivery of Rights Certificates to a Person other than, or the issuance or 

  

 10 

 
delivery of certificates or depositary receipts for the Preferred Shares (or Common Shares and/or other securities, as the case may be) in a name other than
that of, the registered holder of the Rights Certificate evidencing Rights surrendered for exercise or to issue or to deliver any certificates or depositary receipts for Preferred Shares (or Common Shares and/or other securities, as the case may be)
upon the exercise of any Rights until any 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 or the Rights Agent’s
reasonable satisfaction that no such tax or charge is due. 
 (d) So long as the Preferred Shares (and, following the occurrence of a
Distribution Date, Common Shares and/or other securities, as the case may be) issuable and deliverable upon the exercise of the Rights may be listed on any inter-dealer quotation system or national securities exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance to be listed on one such system or exchange upon official notice of issuance upon such exercise. 
 (e) The Company shall use its best efforts to (i) file on the appropriate form, as soon as practicable following the earliest date after the first
occurrence of a Section 11(a)(ii) Event on which the consideration to be delivered by the Company upon exercise of the Rights has been determined hereunder, a registration statement under the Securities Act of 1933, as amended (the
“Act”), with respect to the securities purchasable upon exercise of the Rights, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to
remain effective (with a prospectus at all times meeting the requirements of the Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities, and (B) the Final Expiration Date. The Company
may temporarily suspend, for a period of time not to exceed ninety (90) days after the date set forth in clause (i) of the first sentence of this Section 9(e), 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. In addition, if the Company shall determine that a registration statement is required following the Distribution Date, the Company may temporarily suspend the exercisability of the Rights until such
time as a registration statement has been declared effective. 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 shall notify the Rights Agent whenever it makes a public announcement pursuant to this Section 9 and give the Rights Agent a copy of such announcement. Notwithstanding any provision of this Agreement to
the contrary, the Rights shall not be exercisable in any jurisdiction if the requisite qualification in such jurisdiction shall not have been obtained, the exercise thereof shall not be permitted under applicable law or a registration statement
shall not have been declared effective. 
 Section 10. Preferred Shares Record Date. Each Person in whose name any certificate
for Preferred Shares (or Common Shares and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Preferred Shares (or Common Shares and/or other
securities, as the case may be) represented thereby on, and such certificate shall be dated, the date upon which the Rights 

  

 11 

 
Certificate evidencing such Rights was duly surrendered and payment of the applicable Purchase Price (and any applicable transfer taxes or charges) was made
(or Rights were duly surrendered in exchange for Common Shares pursuant to Section 24 hereof); provided, however, that if the date of such surrender and payment is a date upon which the Preferred Shares (or Common Shares and/or other
securities, as the case may be) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred
Shares (or Common Shares and/or other securities, as the case may be) transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate shall not be entitled to any rights of a holder
of Preferred Shares (or Common Shares and/or other securities, as the case may be) for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein. 
 Section 11.
Adjustment of Purchase Price, Number and Kind of Shares or Number of Rights. The Purchase Price, the number and kind of shares covered by and obtainable upon exercise of each Right, and the number of Rights outstanding, are subject to
adjustment from time to time as provided in this Section 11 and Section 13 hereof. 
 (a) (i) In the event the Company shall at any
time after the date of this Agreement (A) declare a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine the outstanding Preferred Shares into a smaller number of
Preferred Shares or (D) issue any shares of its capital stock in a reclassification of the Preferred Shares (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), 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 proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive 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 Preferred Shares 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 one Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. If an event occurs which would require adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made
prior to, any adjustment required pursuant to Section 11(a)(ii) hereof. 
 (ii) Subject to Section 24 hereof, in the event any
Person shall become an Acquiring Person, each holder of a valid Right shall thereafter have a right to receive, upon exercise thereof at a price equal to the then current Purchase Price multiplied by the number of one ten-thousandths of a Preferred
Share for which a Right is then exercisable, in accordance with the terms of this Agreement, and in lieu of Preferred Shares, such number of Common Shares of the Company as shall equal the result obtained by (x) multiplying the then 

  

 12 

 
current Purchase Price by the number of one ten-thousandths of a Preferred Share for which a Right is then exercisable, and dividing that product by
(y) 50% of the then current per share market price of the Company’s Common Shares (determined pursuant to Section 11(d) hereof) on the date of the occurrence of the event described above. 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. 
 From and after the time when a Person becomes an Acquiring Person (a “Section 11(a)(ii) Event”) any Rights that are or were acquired or
beneficially owned by (i) any Acquiring Person or any Associate or Affiliate of such Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person
became an Acquiring Person 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 an Acquiring Person and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom such Acquiring Person has any continuing agreement, arrangement or
understanding, whether written or oral, regarding the transferred Rights or (B) a transfer which the Board of Directors has determined in good faith is part of a plan, arrangement or understanding, whether written or oral, which has as a
primary purpose or effect the avoidance of this second paragraph of this Section 11(a)(ii), shall each be null and void without any further action and any holder of such Rights shall thereafter have no exercise or any other rights whatsoever
with respect to such Rights under any provision of this Agreement or otherwise. No Rights Certificate shall be issued pursuant to Section 3, this Section 11(a)(ii) or Section 24 that represents Rights beneficially owned by an
Acquiring Person or any Associate or Affiliate thereof whose Rights would be null and void pursuant to the preceding sentence; no Rights Certificate shall be issued at any time upon the transfer of any Rights to an Acquiring Person or any Associate
or Affiliate thereof whose Rights would be null and void pursuant to the preceding sentence or to any nominee of such Acquiring Person, Associate or Affiliate; and any Rights Certificate delivered to the Rights Agent for transfer to an Acquiring
Person, Associate or Affiliate thereof whose Rights would be null and void pursuant to the preceding sentence shall be cancelled. The Company shall give the Rights Agent written notice of the identity of any such Acquiring Person, Associate or
Affiliate, or the nominee of any of the foregoing, and the Rights Agent may rely on such notice in carrying out its duties under this Agreement and shall be deemed not to have any knowledge of the identity of any such Acquiring Person, Associate or
Affiliate, or the nominee of any of the foregoing unless and until it shall have received such notice. 
 (iii) In lieu of issuing Common
Shares of the Company in accordance with Section 11(a)(ii) hereof, the Company may, in the sole discretion of the Board of Directors, elect to (and, in the event that the Board of Directors has not exercised the exchange right contained in
Section 24 hereof and there are not sufficient issued but not outstanding and authorized but unissued Common Shares to permit the exercise in full of the Rights in accordance with Section 11(a)(ii) hereof, the Company shall) take all such
action as may be necessary to authorize, issue or pay, upon the exercise of the Rights, cash (including by way of a reduction of the Purchase Price), property, other securities or any combination thereof having an aggregate value equal to the value
of the Common Shares of the Company which 

  

 13 

 
otherwise would have been issuable pursuant to Section 11(a)(ii), which aggregate value shall be determined by the Board of Directors. For purposes of
the preceding sentence, the value of the Common Shares shall be determined pursuant to Section 11(d) hereof and the value of any equity securities which the Board of Directors determines to be a “common stock equivalent” (including
the Preferred Shares, in such ratio as the Board of Directors shall determine) shall be deemed to have the same value as the Common Shares. Any such election by the Board of Directors must be made and publicly announced within 60 days following the
date on which the event described in Section 11(a)(ii) shall have occurred. Following the occurrence of the event described in Section 11(a)(ii), the Board of Directors may suspend the exercisability of the Rights for a period of up to 60
days following the date on which the event described in Section 11(a)(ii) shall have occurred to the extent that the Board of Directors has not determined whether to exercise the Company’s right of election under this
Section 11(a)(iii). 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. The Company shall notify the Rights Agent whenever it makes a
public announcement pursuant to this Section 11 and give the Rights Agent a copy of such announcement. 
 (b) In case the Company shall
fix a record date for the issuance of rights, options or warrants to all holders of Preferred Shares entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Preferred Shares (or shares
having the same rights, privileges and preferences as the Preferred Shares (“equivalent preferred shares”)) or securities convertible into Preferred Shares or equivalent preferred shares at a price per Preferred Share or equivalent
preferred share (or having a conversion price per share, if a security convertible into Preferred Shares or equivalent preferred shares) less than the then current per share market price of the Preferred Shares (as defined in Section 11(d)) 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 Preferred
Shares outstanding on such record date plus the number of Preferred Shares which could be purchased at the current per share market price for the aggregate offering price of the total number of Preferred Shares and/or equivalent preferred shares so
to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) and the denominator of which shall be the number of Preferred Shares outstanding on such record date plus the number of additional Preferred
Shares and/or equivalent preferred shares 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 in a consideration part or all of which shall be in a form
other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent. Preferred Shares owned by or held for the account of
the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed; and in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. 
  

 14 

 (c) In case the Company shall fix a record date for the making of a distribution to all holders of the
Preferred Shares (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving corporation) of evidences of indebtedness or assets (other than a regular quarterly cash dividend
or a dividend payable in Preferred Shares) 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 then current per share market price of the Preferred Shares on such record date, less the fair market value (as determined in good faith by the Board
of Directors, whose determination shall be described in a statement filed with the Rights Agent) of the portion of the assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to one Preferred
Share and the denominator of which shall be such current per share market price of the Preferred Shares; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of
the shares of capital stock of the Company to be issued upon exercise of one Right. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the Purchase Price shall
again be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. 
 (d) (i) For the purpose
of any computation hereunder, the “current per share market price” of any security (a “Security” for the purpose of this Section 11(d)(i)) on any date shall be deemed to be the average of the daily closing prices (determined
as provided in the next sentence) per share of such Security for the 30 consecutive Trading Days (as such term is hereinafter defined) immediately prior to, but not including, such date, and for the purpose of any computation under
Section 11(a)(iii) hereof, the “current per share market price” of a Security on any date shall be deemed to be the average of the daily closing prices per share of such Security for the 30 consecutive Trading Days immediately
following, but not including, such date; provided, however, that in the event that the current per share market price 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 such shares (other than the Rights), or (B) any subdivision, combination or reclassification of such Security and prior to the expiration of 30
Trading Days 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 per share market price shall be appropriately adjusted to
reflect the current market price per share equivalent of such Security as if such dividend, distribution, combination or reclassification has not been declared. 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 on the Nasdaq National Market
or, if the Security is listed or admitted for trading on a national 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 on the Nasdaq National Market or 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 any other system then in use, or, if on any such date the Security is not quoted by any such organization, the average of the closing bid and asked prices 

  

 15 

 
as furnished by a professional market maker making a market in the Security selected by the Board of Directors. The term “Trading Day” shall mean a
day on which the inter-dealer quotation system or principal national securities exchange on which the Security 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
inter-dealer quotation system or national securities exchange, a Business Day. 
 (ii) For the purpose of any computation hereunder, the
“current per share market price” of the Preferred Shares shall be determined in accordance with the method set forth in Section 11(d)(i) hereof. If the Preferred Shares are not publicly traded, the “current per share market
price” of the Preferred Shares shall be conclusively deemed to be the current per share market price of the Common Shares as determined pursuant to Section 11(d)(i) (appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof), multiplied by ten-thousand. If neither the Common Shares nor the Preferred Shares are publicly held or so listed or traded, “current per share market price” shall mean the fair value
per share as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent. 
 (e) No adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Purchase Price; provided, however, that any adjustments 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 one-millionth of a
Preferred Share or one ten-thousandth of any other share or security, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of
(i) three years from the date of the transaction which requires such adjustment or (ii) 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) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than
Preferred Shares, thereafter the number of such other shares so receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the
Preferred Shares contained in Sections 11(a), 11(b) and 11(c), and the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares shall apply on like terms to any such other shares. 
 (g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase,
at the adjusted Purchase Price, the number of one ten-thousandths of a Preferred Share purchasable from time to time hereunder upon exercise of the Rights all subject to further adjustment as provided herein. 
 (h) Unless the Company shall have exercised its election as provided in Section 11(i) hereof, upon each adjustment of the Purchase Price as a
result of the calculations made in Sections 11(b) and 11(c) hereof, each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted 

  

 16 

 
Purchase Price, that number of one ten-thousandths of a Preferred Share (calculated to the nearest one one-millionth of a Preferred Share) obtained by
(i) multiplying (x) the number of one ten-thousandths of a share covered by a Right immediately prior to this adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and
(ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price. 
 (i)
The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in substitution for any adjustment in the number of one ten-thousandths of a Preferred Share purchasable upon the exercise of a Right.
Each of the Rights outstanding after such adjustment of the number of Rights shall be exercisable for the number of one ten-thousandths of a Preferred Share for which a Right was exercisable immediately prior to such adjustment. Each Right held of
record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement (with prompt written notice thereof to the Rights Agent) of its election to adjust the number of Rights, indicating the record
date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be
at least 10 days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be
distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14 hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the
option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company,
new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein and 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 ten-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 ten-thousandths of a Preferred Share which were expressed in the initial Rights Certificates issued hereunder, without prejudice to the validity of such Rights Certificate(s) or the application of the provisions
hereof. 
 (k) Before taking any action that would cause an adjustment reducing the Purchase Price below one ten-thousandth of the then 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 fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price. 
  

 17 

 (l) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be
made effective as of a record date for a specified event, the Company may elect to defer (with prompt written notice thereof to the Rights Agent) until the occurrence of such event the issuing to the holder of any Right exercised after such record
date of the Preferred Shares and other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Preferred Shares 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
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 it in its sole discretion shall determine to be advisable in order that
any consolidation or subdivision of the Preferred Shares, issuance wholly for cash of any Preferred Shares at less than the current market price, issuance wholly for cash of Preferred Shares or securities which by their terms are convertible into or
exchangeable for Preferred Shares, dividends on Preferred Shares payable in Preferred Shares or issuance of rights, options or warrants referred to in Section 11(b), hereafter made by the Company to holders of its Preferred Shares shall not be
taxable to such stockholders. 
 (n) In the event that at any time after the date of this Agreement and prior to the Shares Acquisition
Date, the Company shall (i) declare or pay any dividend on the Common Shares payable in Common Shares or (ii) effect a subdivision, combination or consolidation of the Common Shares (by reclassification or otherwise than by payment of
dividends in Common Shares) into a greater or lesser number of Common Shares, then in any such case (i) the number of one ten-thousandths of a Preferred Share purchasable after such event upon proper exercise of each Right shall be determined
by multiplying the number of one ten-thousandths of a Preferred Share so purchasable immediately prior to such event by a fraction, the numerator of which is the number of Common Shares outstanding immediately before such event and the denominator
of which is the number of Common Shares outstanding immediately after such event, and (ii) each Common Share outstanding immediately after such event shall have issued with respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments provided for in this Section 11(n) shall be made successively whenever such a dividend is declared or paid or such a subdivision, combination or consolidation is
effected. 
 Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as provided
in Section 11 and 13 hereof, the Company shall promptly (a) prepare a certificate setting forth such adjustment, and a brief statement of the facts accounting for such adjustment, (b) file with the Rights Agent and with each transfer
agent for the Common Shares or the Preferred Shares a copy of such certificate and (c) mail a brief summary thereof to each holder of a Rights Certificate in accordance with Section 25 hereof. The Rights Agent shall be fully protected in
relying on any such certificate and on any adjustment or statement therein contained and shall have no duty or liability with respect to, and shall not be deemed to have knowledge of, any adjustment or any such event unless and until it shall have
received such a certificate. 
  

 18 

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

(a) If, after the Shares Acquisition Date, directly or indirectly, (w) the Company shall consolidate with, or merge with and into, any other
Person, (x) any Person shall consolidate with the Company, or merge with and into the Company and the Company shall be the continuing or surviving corporation of such merger and, in connection with such merger or consolidation all or part of
the outstanding Common Shares are changed into or exchanged for stock or other securities of any other Person (or the Company) or cash or any other property, (y) the Company shall sell, mortgage or otherwise transfer (or one or more of its
Subsidiaries shall sell, mortgage or otherwise transfer), in one or more 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 other than the
Company or one or more of its wholly-owned Subsidiaries, or (z) any Acquiring Person or any Associate or Affiliate of any such Acquiring Person, at any time after the date of this Agreement, directly or indirectly, (A) shall, in one
transaction or a series of transactions, transfer any assets to the Company or to any of its Subsidiaries in exchange (in whole or in part) for Common Shares, for shares of other equity securities of the Company or for securities exercisable for or
convertible into shares of equity securities of the Company (Common Shares or otherwise) or otherwise obtain from the Company, with or without consideration, any additional shares of such equity securities or securities exercisable for or
convertible into shares of such equity securities (other than pursuant to a pro rata distribution to all holders of Common Shares), (B) shall sell, purchase, lease, exchange, mortgage, pledge, transfer or otherwise acquire or dispose of assets,
in one transaction or a series of transactions, to, from or with the Company or any of its Subsidiaries without obtaining a written opinion from a nationally recognized investment banking firm that the terms of such transaction or arrangement are no
less favorable to the Company than the Company would be able to obtain in arm’s-length negotiation with an unaffiliated third party, (C) shall sell, purchase, lease, exchange, mortgage, pledge, transfer or otherwise acquire or dispose of
in one transaction or a series of transactions, to, from or with the Company or any of the Company’s Subsidiaries (other than incidental to the lines of business, if any, engaged in as of the date hereof between the Company and such Acquiring
Person or Associate or Affiliate) assets having an aggregate fair market value of more than $5,000,000, (D) shall receive any compensation from the Company or any of the Company’s Subsidiaries other than compensation for full-time
employment as a regular employee at rates in accordance with the Company’s (or its Subsidiaries’) past practices, or (E) shall receive the benefit, directly or indirectly (except proportionately as a stockholder and except if
resulting from a requirement of law or governmental regulation), of any loans, advances, guarantees, pledges or other financial assistance or any tax credits or other tax advantage provided by the Company or any of its Subsidiaries, then, and in
each such case, (i) each holder of a Right (except as otherwise provided herein) shall thereafter have the right to receive, upon the exercise thereof at a price equal to the then current Purchase Price multiplied by the number of one
ten-thousandths of a Preferred Share for which a Right is then exercisable in accordance with the terms of this Agreement, and in lieu of Preferred Shares, such number of validly authorized and issued, fully paid, non-assessable and freely tradeable
Common Shares of the Principal Party (as hereinafter defined) not subject to any liens, encumbrances, rights of first refusal or other adverse claims, as shall equal the result obtained by (A) multiplying the then current Purchase Price by the
number of one ten-thousandths of a Preferred Share for which a Right is then exercisable and dividing 

  

 19 

 
that product by (B) 50% of the then current per share market price of the Common Shares of the Principal Party (determined pursuant to
Section 11(d) hereof) on the date of consummation of such consolidation, merger, sale or transfer; (ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such consolidation, merger, sale or transfer, all
the obligations and duties of the Company pursuant to this Agreement; (iii) the term “Company” shall thereafter be deemed to refer to such Principal Party; and (iv) such Principal Party shall take such steps (including, but not
limited to, the reservation of a sufficient number of its Common Shares in accordance with Section 9 hereof) in connection with such consummation as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly
as reasonably may be, in relation to the Common Shares thereafter deliverable upon the exercise of the Rights. 
 (b) “Principal
Party” shall mean: 
 (i) In the case of any transaction described in (w) or (x) of the first sentence of Section 13(a)
hereof, the Person that is the issuer of any securities into which Common Shares of the Company are converted in such merger or consolidation, and if no securities are so issued, the Person that is the surviving entity of such merger or
consolidation (including the Company if applicable); and 
 (ii) in the case of any transaction described in (y) or (z) of the
first sentence in Section 13(a) hereof, the Person that is the party receiving the greatest portion of the assets, securities, earning power or other benefit transferred pursuant to such transaction or transactions; 
 provided, however, that in any such case described in clauses (b)(i) and (b)(ii): (1) if the Common Shares of such Person are not at such time and
have not been continuously over the preceding 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 Shares of which are and have been so registered,
“Principal Party” shall refer to such other Person; (2) in case such Person is a Subsidiary, directly or indirectly, of more than one Person, the Common Shares 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 Shares having the greatest aggregate market value; and (3) in case such Person is owned, directly or indirectly, by a joint venture formed by two or more Persons
that are not owned, directly or indirectly, by the same Person, the rules set forth in (1) and (2) above shall apply to each of the chains of ownership having an interest in such joint venture as if such party were a “Subsidiary”
of both or all of such joint venturers and the Principal Parties in each such chain shall bear the obligations set forth in this Section 13 in the same ratio as their direct or indirect interests in such Person bear to the total of such
interests. 
 (c) The Company shall not consummate any such consolidation, merger, sale or transfer unless the Principal Party shall have
sufficient Common Shares authorized to permit the full exercise of the Rights and 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
Sections 13(a) and 13(b) hereof and further providing that, as soon as practicable after the date of any consolidation, merger, sale or transfer mentioned in Section 13(a) hereof, 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 Final Expiration Date; 
  

 20 

 (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; and 
 (iii) take
such actions as may be necessary or appropriate under the blue sky laws of the various states. The 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. The
provisions of this Section 13 shall similarly apply to successive mergers, consolidations, sales or transfers. 
 Section 14.
Fractional Rights and Fractional Shares. 
 (a) The Company shall not be required to issue fractions of Rights 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 otherwise be issuable, an amount in cash
equal to the same fraction of the current market value of a whole Right. For the 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 for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the principal national securities exchange or the Nasdaq National Market 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 or the Nasdaq National Market, 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 any 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. 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 shall
be used. 
 (b) The Company shall not be required to issue fractions of Preferred Shares (other than fractions which are integral multiples
of one ten-thousandth of a Preferred Share) upon exercise of the Rights or to distribute certificates which evidence fractional Preferred Shares (other than fractions which are integral multiples of one ten-thousandth of a Preferred Share).
Fractions of Preferred Shares in integral multiples of one ten-thousandth of a Preferred Share may, at the election of the Company, be evidenced by depositary receipts, 

  

 21 

 
pursuant to an appropriate agreement between the Company and a depositary selected by it; provided, that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners of the Preferred Shares represented by such depositary receipts. In lieu of fractional Preferred Shares that are not
integral multiples of one ten-thousandth of a Preferred Share, the Company shall pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the
current market value of one Preferred Share. For the purposes of this Section 14(b), the current market value of a Preferred Share shall be the closing price of a Preferred Share (as determined pursuant to the second sentence of
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of such exercise. 
 (c) Following the occurrence of a
Distribution Date, the Company shall not be required to issue fractions of Common Shares upon exercise of the Rights or to distribute certificates which evidence fractional Common Shares. In lieu of fractional Common Shares, the Company may pay to
the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one Common Share. For purposes of this Section 14(c), the current
market value of one Common Share shall be the closing price of one Common Share (as determined pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of such exercise. 
 (d) The holder of a Right by the acceptance of the Right expressly waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above). 
 (e) Whenever a payment for fractional Rights or fractional shares is to be made by the
Rights Agent, the Company shall (i) promptly prepare and deliver to the Rights Agent a certificate setting forth in reasonable detail the facts related to such payments and the prices and/or formulas utilized in calculating such payments, and
(ii) provide sufficient monies to the Rights Agent in the form of fully collected funds to make such payments. The Rights Agent shall be fully protected in relying upon such a certificate and shall have no duty with respect to, and shall not be
deemed to have knowledge of any payment for fractional Rights or fractional shares under any Section of this Agreement relating to the payment of fractional Rights or fractional shares unless and until the Rights Agent shall have received such a
certificate and sufficient monies. 
 Section 15. Rights of Action. All rights of action in respect of this Agreement, excepting
the rights of action given to the Rights Agent under Section 18 hereof, are vested in the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common Shares); and any
registered holder of any Rights Certificate (or, prior to the Distribution Date, of the Common Shares), 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
Shares), may, in its own behalf and for its own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, its right to exercise the Rights evidenced by such Rights
Certificate in the manner provided in such Rights Certificate and in this Agreement. Without limiting the 

  

 22 

 
foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at
law for any breach of this Agreement and will 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 accepting the same, consents and agrees with the Company and the Rights
Agent and with every other holder of a Right that: 
 (a) prior to the Distribution Date, the Rights will be transferable only in connection
with the transfer of the Common Shares; 
 (b) after the Distribution Date, the Rights Certificates will be transferable only on the
registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer and with appropriate forms and certificates fully executed; 

(c) the Company and the Rights Agent may deem and treat the Person in whose name the Rights Certificate (or, prior to the Distribution Date, the
associated certificate for Common Shares) 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 certificate for Common
Shares made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary; and 
 (d) notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a
Right or any other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, judgment, decree or ruling (whether interlocutory or final) issued by
a court or by a governmental, regulatory, self-regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority prohibiting or otherwise restraining
performance of such obligation; provided, however, that the Company must use all reasonable efforts to have any such injunction order, judgment, decree or ruling lifted or otherwise overturned as soon as possible. 
 Section 17. Rights Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Rights Certificate shall be entitled to vote,
receive dividends or be deemed for any purpose the holder of the Preferred Shares or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in
any Rights Certificate be construed to confer upon the holder of any Rights Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 25 hereof), or to receive dividends or subscription rights, or
otherwise, until the Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof. 
  

 23 

 Section 18. Concerning the Rights Agent. The Company agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the preparation, deliver, amendment, administration
and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim,
demand, settlement, cost or expense (including, without limitation, the reasonable fees and expenses of legal counsel), incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent (which gross negligence, bad
faith or willful misconduct must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction), for any action taken, suffered or omitted by the Rights Agent in connection with the acceptance,
administration, exercise and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising, directly or indirectly, therefrom. The costs and expenses incurred in enforcing this
right of indemnification shall be paid by the Company. The provisions of this Section 18 and Section 20 below shall survive the resignation, replacement, removal or substitution of the Rights Agent, the termination of this Agreement and
the exercise or expiration of the Rights. Anything to the contrary notwithstanding, in no case shall the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damage of any kind whatsoever (including but not
limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. Any liability of the Rights Agent under this Agreement will be limited to the amount of fees paid by the Company to the Rights Agent.

 The Rights Agent shall be authorized and protected and shall incur no liability for, or in respect of any action taken, suffered or
omitted by it in connection with, its acceptance and administration of this Agreement and the exercise and performance of its duties hereunder, in reliance upon any Rights Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed,
executed and, where necessary, verified or acknowledged, by the proper Person or Persons, or otherwise upon the advice of counsel as set forth in Section 20 hereof. The Rights Agent shall not be deemed to have knowledge of any event of which it
was supposed to receive notice thereof hereunder, and the Rights Agent shall be fully protected and shall incur no liability for failing to take any action in connection therewith unless and until it has received such notice. 
 Section 19. Merger or Consolidation or Change of Name of Rights Agent. Any Person into which the Rights Agent or any successor Rights Agent
may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the shareholder services business of
the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such Person would
be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement any of the Rights Certificates shall have
been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall
not have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall
have the full force provided in the Rights Certificates and in this Agreement. 
  

 24 

 In case at any time the name of the Rights Agent shall be changed and at such time any of the Rights
Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not
have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in
this Agreement. 
 Section 20. Duties of Rights Agent. The Rights Agent undertakes to perform only the duties and obligations
expressly imposed by this Agreement (and no implied duties) upon the following terms and conditions by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound: 
 (a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company or an employee of the Rights Agent), and the advice or
opinion of such counsel shall be full and complete authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted by it in the absence of gross negligence,
bad faith or willful misconduct in accordance with such advice or opinion. 
 (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter (including without limitation, the identity of an Acquiring Person and the determination of the current per share market price of any security) be proved or
established by the Company prior to taking, suffering or omitting to take any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established
by a certificate signed by any one of the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer or the Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full and
complete authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted by it under the provisions of this Agreement in reliance upon such certificate.

 (c) The Rights Agent shall be liable hereunder to the Company and any other Person only for its own gross negligence, bad faith or
willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction). 
  

 25 

 (d) The Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals
contained in this Agreement or in the Rights Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Company only. 
 (e) The Rights Agent shall not be have any liability for or be under any responsibility in respect of the validity of this Agreement or the execution
and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Rights Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Rights Certificate; nor shall it be responsible for any change in the exercisability of the Rights (including the Rights becoming null and void pursuant to Section 11(a)(ii) hereof) or
any change or adjustment in the terms of the Rights (including the manner, method or amount thereof) provided for in Section 3, 11, 13, 23 or 24 hereof, or the ascertaining of the existence of facts that would require any such change or
adjustment (except with respect to the exercise of Rights evidenced by Rights Certificates after receipt of a certificate described in Section 12 hereof, upon which the Rights Agent may rely); nor shall it by any act hereunder be deemed to make
any representation or warranty as to the authorization or reservation of any Preferred Shares (or Common Shares and/or other securities, as the case may be) to be issued pursuant to this Agreement or any Rights Certificate or as to whether any
Preferred Shares (or Common Shares and/or other securities, as the case may be) will, when issued, be validly authorized and issued, fully paid and nonassessable. 
 (f) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement. 
 (g) The Rights Agent is hereby authorized and directed to accept, prior to the Shares Acquisition Date, instructions with respect to the performance of its duties hereunder from any one of the Chairman of the Board, the Chief Executive
Officer, the President, any Vice President, the Secretary or the Treasurer of the Company, and to apply to such officers for advice or instructions in connection with its duties, such instructions shall be full authorization and protection to the
Rights Agent and the Rights Agent shall not be liable for or in respect of any action taken, suffered or omitted by it in accordance with instructions of any such officer or for any delay in acting while waiting for those instructions. The Rights
Agent shall be fully authorized and protected in relying upon the most recent instructions received by any such officer. Any application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth
in writing any action proposed to be taken, suffered or omitted by the Rights Agent under this Agreement and the date on and/or after which such action shall be taken or suffered or such omission shall be effective. The Rights Agent shall not be
liable for any action taken or suffered by, or omission of, the Rights Agent in accordance with a proposal included in any such application on or after the date specified in such application (which date shall not be less than five Business Days
after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to an earlier date) unless, prior to taking any such action (or the effective date in the case of an omission), the
Rights Agent shall have received written instructions in response to such application specifying the action to be taken, suffered or omitted. 
  

 26 

 (h) The Rights Agent and any stockholder, affiliate, director, officer or employee of the Rights Agent
may buy, sell or deal in any of the Rights or other securities of the Company, or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and
freely as though the Rights Agent were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent or any such stockholder, affiliate, director, officer or employee from acting in any other capacity for the Company or for
any other Person. 
 (i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty
hereunder either itself (through its directors, officers and employees) or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents
or for any loss to the Company or any other Person resulting from any such act, default, neglect or misconduct absent gross negligence, bad faith or willful misconduct in the selection and continued employment thereof (which gross negligence, bad
faith or willful misconduct must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction). 
 (j) If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate contained in the form of assignment or the form of election to purchase set forth on the reverse thereof, as the case
may be, has either not been completed or indicates an affirmative response to clause 1 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.

 (k) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder or in the exercise of its rights if it believes that repayment of such funds or adequate indemnification against such risk or liability is not assured to it. 
 Section 21. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and thereafter be discharged from its duties
under this Agreement upon 30 days’ notice in writing mailed to the Company and to each transfer agent of the Common Shares or Preferred Shares known to the Rights Agent by registered or certified mail, and to the holders of the Rights
Certificates by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon 30 days’ notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the
Common Shares or Preferred Shares by registered or certified mail, and to the holders of the Rights Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall
appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of 30 days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Rights Certificate (who shall, with such notice, submit his Rights Certificate for inspection by the Company), then the registered holder 

  

 27 

 
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 either (A) a Person organized and doing business under the laws of the United States or of any state of the United States, in good standing, authorized under such laws to exercise corporate
trust or stock transfer powers, and subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50 million or (B) an affiliate of
such a Person. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent
shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such
appointment the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares or 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
Agreement or of the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change in the Purchase Price and the
number or kind or class of shares or other securities or property purchasable under the Rights Certificates made in accordance with the provisions of this Agreement. 
 Section 23. Redemption. 
 (a) The Rights may be redeemed by action of the Board of Directors
pursuant to Section 23 (b) hereof and shall not be redeemed in any other manner. 
 (b) The Board of Directors may, at its option,
at any time prior to such time as any Person becomes an Acquiring Person, redeem all, but not less than all, of the then outstanding Rights at a redemption price of $.01 per Right, 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 by the Board of Directors may be made effective at such time on such basis
and with such conditions as the Board of Directors in its sole discretion may establish. If redemption of the Rights is to be effective as of a future date, the Rights shall continue to be exercisable, subject to Section 11(a)(ii) hereof, until
the effective date of the redemption, provided that nothing contained herein shall preclude the Board of Directors from subsequently causing the Rights to be redeemed at a date earlier than the previously scheduled effective date of the redemption.
The Company may, at its option, pay the Redemption Price in cash, Common Shares (based on the current per share market price of the Common Shares at the time of redemption) or any other form of consideration deemed appropriate by the Board of
Directors. 
  

 28 

 (c) Immediately upon the action of the Board of Directors ordering the redemption of the Rights pursuant
to Section 23(b) hereof (or at the effective time of such redemption established by the Board of Directors pursuant to Section 23(b) hereof), 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. The Company shall promptly give public notice of any such redemption (with prompt written notice thereof to the Rights Agent); provided,
however, that the failure to give, or any defect in, any such notice shall not affect the legality or validity of such redemption. Within 10 days after such action of the Board of Directors ordering the redemption of the Rights pursuant to
Section 23(b) hereof or if later, the effectiveness of the redemption of the rights pursuant to the last sentence of Section 23(b), the Company shall mail a notice of redemption to all the holders of the then outstanding Rights at their
last addresses as they appear 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 Shares. 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. The Company may, at its option, discharge all of its obligations with respect to
the Rights by (i) issuing a press release announcing the manner of redemption of the Rights (with prompt written notice thereof to the Rights Agent), (ii) depositing with a bank or trust company having a capital and surplus of at least
$100 million, funds necessary for such redemption, in trust, to be applied to the redemption of the Rights so called for redemption and (iii) arranging for the mailing of the Redemption Price to the registered holders of the Rights; then, and
upon such action, all outstanding Rights Certificates shall be null and void without further action by the Company. 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 24 hereof, and other than in connection with the purchase of Common Shares prior to the Shares Acquisition Date. 
 Section 24. Exchange. 
 (a) The
Board of Directors may, at its option, at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become null and void pursuant to the
provisions of Section 11(a)(ii) hereof) for Common Shares at an exchange ratio of one Common Share per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof.
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 Shares for or pursuant to the terms of any such plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the Common Shares then outstanding.

 (b) Immediately upon the action of the Board of Directors ordering the exchange of any Rights pursuant to Section 24(a) hereof 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 Common Shares equal to the number of valid Rights held
by such holder. The Company shall promptly give public notice of 

  

 29 

 
any such exchange (with prompt written notice thereof to the Rights Agent); provided, however, that the failure to give, or any defect in, such notice shall
not affect the legality or validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice
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 Shares 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 null and void pursuant to the provisions of
Section 11(a)(ii) hereof) held by each holder of Rights. 
 (c) In any exchange pursuant to this Section 24, the Company, at its
option, may substitute Preferred Shares (or equivalent preferred shares, as such term is defined in Section 11(b) hereof) for Common Shares exchangeable for Rights, at the initial rate of one ten-thousandth of a Preferred Share (or equivalent
preferred share) for each Common Share, as appropriately adjusted to reflect adjustments in the voting rights of the Preferred Shares pursuant to the terms thereof, so that the fraction of a Preferred Share delivered in lieu of each Common Share
shall have the same voting rights as one Common Share. 
 (d) In the event that there shall not be sufficient Common Shares or Preferred
Shares issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 24, the Company shall take all such action as may be necessary to authorize additional Common Shares
or Preferred Shares for issuance upon exchange of the Rights. 
 (e) The Company shall not be required to issue fractions of Common Shares
or to distribute certificates which evidence fractional Common Shares. In lieu of such fractional Common Shares, the Company shall pay to the registered holders of the Rights Certificates with regard to which such fractional Common Shares would
otherwise be issuable an amount in cash equal to the same fraction of the current market value of a whole Common Share. For the purposes of this Section 24(e), the current market value of a whole Common Share shall be the closing price of a
Common Share (as determined pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of exchange pursuant to this Section 24. 
 Section 25. Notice of Certain Events. 
 (a) In case the Company shall propose (i) to pay any dividend payable in stock of any class to the holders of its Preferred Shares or to make any other distribution to the holders of its Preferred Shares (other than a regular quarterly
cash dividend), (ii) to offer to the holders of its Preferred Shares rights or warrants to subscribe for or to purchase any additional Preferred Shares or shares of stock of any class or any other securities, rights or options, (iii) to
effect any reclassification of its Preferred Shares (other than a reclassification involving only the subdivision of outstanding Preferred Shares), (iv) to effect any consolidation or merger into or with, 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 or more transactions, of 50% or more of the assets or earning 

  

 30 

 
power of the Company and its Subsidiaries (taken as a whole) to, any other Person, (v) to effect the liquidation, dissolution or winding up of the
Company, or (vi) to declare or pay any dividend on the Common Shares payable in Common Shares or to effect a subdivision, combination or consolidation of the Common Shares (by reclassification or otherwise), then, in each such case, the Company
shall give to the Rights Agent and to each holder of a Rights Certificate, in accordance with Section 26 hereof, a notice of such proposed action, which shall specify the record date for such event, and the date of participation therein by the
holders of the Common Shares and/or Preferred Shares, 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 10 days prior to the record date for
determining holders of the Preferred Shares for purposes of such action, and in the case of any such other action, at least 10 days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the
Common Shares and/or Preferred Shares, whichever shall be the earlier. 
 (b) In case any of the events set forth in Section 11(a)(ii)
hereof shall occur, then the Company shall as soon as practicable thereafter give to the Rights Agent and to each holder of a Rights Certificate, in accordance with Section 26 hereof, a notice of the occurrence of such event, which notice shall
describe such event and the consequences of such event to holders of Rights under Section 11(a)(ii) hereof.

 EXHIBIT A 
 FORM OF CERTIFICATE OF DESIGNATIONS 
 OF SERIES A JUNIOR PARTICIPATING PREFERRED STOCK 
 OF NANOPHASE TECHNOLOGIES CORPORATION 
 (Pursuant to Section 151 of the Delaware General Corporation Law) 
 NANOPHASE TECHNOLOGIES CORPORATION, a corporation
organized and existing under the General Corporation Law of the State of Delaware (hereinafter called the “Company”), hereby certifies that the following resolution was adopted by the Board of Directors of the Company as required by
Section 151 of the General Corporation Law at a meeting duly called and held on October 26, 1998: 
 RESOLVED, that pursuant to the
authority granted to and vested in the Board of Directors of this Company (hereinafter called the “Board of Directors” or the “Board”) in accordance with the provisions of the Company’s Certificate of Incorporation, the
Board of Directors hereby creates a series of Preferred Stock, par value $.01 per share (the “Preferred Stock”), of the Company 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 initially be 2,500. 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 or rights issued by the Company convertible into Series A Preferred Stock and further provided that the Board of Directors shall increase the number of shares constituting the Series A Preferred Stock to
the extent necessary for the Company to have available sufficient shares of such Series A Preferred Stock available to fulfill all of the Company’s obligations to holders of securities and Rights of the Company. 
 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 Company, and of any other junior stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of the
funds legally available for the purpose, dividends payable when and as dividends are declared on the Common Stock in an amount, subject to the provision for adjustment hereinafter set forth, equal to 10,000 times the aggregate per share amount of
all cash dividends, and 10,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions, declared on the Common Stock (except as provided in the next 

  

 A-1 

 
sentence). In the event the Company 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 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 Company shall declare a dividend or distribution on the Series A Preferred Stock as provided in paragraph (A) of this Section 2
immediately after it declares a dividend or distribution on the Common Stock. 
 Section 3. Voting Rights. The holders of shares
of Series A Preferred Stock shall have the following voting rights: 
 (C) Each share of Series A Preferred Stock shall entitle the holder
thereof to 10,000 votes on all matters submitted to a vote of the stockholders of the Company. 
 (D) Except as otherwise provided herein,
in any other Certificate 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 Company
having general voting rights shall vote together as one class on all matters submitted to a vote of stockholders of the Company. 
 (E)
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. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Company 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 Company’s Certificate of Incorporation, or in any other Certificate of Designations creating a series of
Preferred Stock or any similar stock or as otherwise required by law. 
 Section 5. Liquidation, Dissolution or Winding Up. Upon
any liquidation, dissolution or winding up of the Company, 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 an aggregate amount per share, subject to the provision for adjustment hereinafter set forth, equal to 10,000 times the aggregate amount to be
distributed per share to holders of shares of Common Stock. In the event the Company shall at any time declare 

  

 A-2 

 
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 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 6. Consolidation, Merger, etc. In case the Company 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 10,000 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 Company 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 7. No Redemption. The shares of Series A Preferred Stock shall
not be redeemable. 
 Section 8. 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 Company’s Preferred Stock. 
 Section 9. Amendment.
The Certificate of Incorporation of the Company 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.

 EXHIBIT C 
 SUMMARY OF RIGHTS TO PURCHASE 
 PREFERRED SHARES UNDER PLAN ADOPTED BY 
 NANOPHASE TECHNOLOGIES CORPORATION 
 On
October 26, 1998, the Board of Directors of Nanophase Technologies Corporation (the “Company”) declared a dividend of one Right for each outstanding share of common stock (a “Right”), par value $.01 per share (the
“Common Shares”), of the Company. The dividend is payable on November 10, 1998 (the “Record Date”) to the stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one
ten-thousandth of a share of Series A Junior Participating Preferred Stock, par value $.01 per share (the “Preferred Shares”), of the Company at a price of $25.00 per one ten-thousandth of a Preferred Share (the “Purchase
Price”), subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement, as amended (the “Rights Agreement”) between the Company and Mellon Investor Services LLC, as Rights Agent (the “Rights
Agent”). 
 Until the earlier of (i) the Close of Business on the tenth day after the first public announcement that a Person or
group of affiliated or associated Persons have acquired beneficial ownership of 35% or more of the outstanding Common Shares (an “Acquiring Person”), or (ii) the Close of Business on the tenth day (or such later date as may be
determined by action of the Company’s Board of Directors prior to such time as any Person becomes an Acquiring Person) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of
which would result in the beneficial ownership of such Person or group of 35% or more of such outstanding Common Shares (the earlier of such dates being called the “Distribution Date”), the Rights will be evidenced by the Common Share
certificates, will be transferable only by the transfer of the Common Shares associated with such Rights and any transfer of the Common Shares (including a transfer to the Company) will constitute a transfer of the Rights. As described below, after
a Person or group becomes an Acquiring Person, the Rights may not be redeemed or amended. 
 Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Common Share certificates issued after the Record Date, upon transfer or new issuance of Common Shares, will contain a legend incorporating the Rights Agreement by reference. Until the Distribution Date
(or earlier redemption or expiration of the Rights), the surrender for transfer of any certificates for Common Shares outstanding as of the Record Date, even without such notation or a copy of this Summary of Rights being attached, will also
constitute the transfer of the Rights associated with the Common Shares represented by such certificate. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Rights Certificates”) will be
mailed to holders of record of the Common Shares as of the Close of Business on the Distribution Date and such separate Rights Certificates alone will evidence the Rights. Each Right is exercisable for one-ten thousandth of a Preferred Share at any
time after the Distribution Date. 
 The Rights are not exercisable for Common Shares until a Person or group becomes an Acquiring Person.
The Rights will expire on October 28, 2011 (the “Final Expiration Date”), unless the Final Expiration Date is extended or unless the Rights are redeemed earlier by the Company, in each case, as described below. 
  

 C-1 

 If a Person or group of affiliated or associated Persons becomes an Acquiring Person, each holder of a
Right (other than those described in the next sentence) will thereafter have the right to receive, upon exercise, Common Shares (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the
Purchase Price of the Right. All Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null and void. 
 At any time after the first date of public announcement by the Company or an Acquiring Person than an Acquiring Person has become such, if (i) the
Company is the surviving corporation in a merger with any other company or entity, (ii) the Company is acquired in a merger or other business combination transaction, (iii) 50% or more of the Company’s consolidated assets or earning
power are sold, or (iv) an Acquiring Person engages in certain “self-dealing” transactions with the Company, each holder of a Right (other than those whose Rights have become null and void) will thereafter have the right to receive,
upon the exercise thereof at the then current Purchase Price of the Right, that number of shares of common stock of the surviving or acquiring company which at the time of such transaction will have a market value of two times the Purchase Price of
such Right. 
 At any time after a Person or group becomes an Acquiring Person and prior to the acquisition by such Person or group of 50% or
more of the outstanding Common Shares, the Board of Directors of the Company may exchange the Rights (other than Rights owned by such Person or group which have become null and void), in whole or in part, without any additional payment, for Common
Shares at an exchange ratio of one Common Share (or of a share of a class or series of the Company’s preferred shares having equivalent rights, preferences and privileges), per Right (subject to adjustment). 
 With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least 1% in such
Purchase Price. No fractional Preferred Shares will be issued (other than fractions which are integral multiples of one ten-thousandth of a Preferred Share, which may, at the election of the Company, be evidenced by depositary receipts) and in lieu
thereof, an adjustment in cash will be made based on the market price of the Preferred Shares on the last trading day prior to the date of exercise. 
 At any time prior to a Person or group becoming an Acquiring Person, the Board of Directors of the Company may redeem all, but not less than all, of the Rights at a price of $.01 per Right (the “Redemption
Price”). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish. 
 Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price. 
 Any of the provisions of the Rights may be amended by the Board of Directors of the Company in order to cure
any ambiguity or to make any other changes which the Board 

  

 C-2 

 
deems necessary or desirable. However, after a Person or group becomes an Acquiring Person, any such amendment must not adversely affect the interests of
holders of Rights (excluding the interests of any Acquiring Person). 
 A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 8-A dated November __, 1998. A copy of the Rights Agreement is available free of charge from the Company. This summary description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement, which is hereby incorporated herein by reference.
