 PREFERRED STOCK RIGHTS AGREEMENT 
  
 This Preferred Stock Rights Agreement is dated as of December 30, 2002 (this “Agreement”), between
Centillium Communications, Inc., a Delaware corporation (the “Company”), and Mellon Investor Services LLC, a New Jersey limited liability company, as Rights Agent (the “Rights
Agent”). 
  
 On December 27, 2002, (the “Rights Dividend Declaration
Date”), the Board of Directors of the Company authorized and declared a dividend of one Preferred Share Purchase Right (a “Right”) for each Common Share (as hereinafter defined) of the Company outstanding as of
the Close of Business (as hereinafter defined) on January 9, 2003 (the “Record Date”), each Right representing the right to purchase one one-thousandth (0.001) of a share of Series A Participating Preferred Stock (as such
number may be adjusted pursuant to the provisions of this Agreement), having the rights, preferences and privileges set forth in the form of Certificate of Designation of Rights, Preferences and Privileges of Series A Participating Preferred Stock
attached hereto as Exhibit A, upon the terms and subject to the conditions herein set forth, and further authorized and directed the issuance of one Right (as such number may be adjusted pursuant to the provisions of this Agreement) with
respect to each Common Share that shall become outstanding between the Record Date and the earlier of the Distribution Date and the Expiration Date (as such terms are hereinafter defined), and in certain circumstances after the Distribution Date.

  
 NOW, THEREFORE, in consideration of the promises and the mutual agreements herein set forth, the parties hereby
agree as follows: 
  
 Section 1.    Certain Definitions.    For
purposes of this Agreement, the following terms have the meanings indicated: 
  
 (a)    “Acquiring Person” shall mean any Person, who or which, together with all Affiliates and Associates of such Person, shall be the Beneficial Owner of 15% or more of the Common Shares
then outstanding, but shall not include the Company, any Subsidiary of the Company or any employee benefit plan of the Company or of any Subsidiary of the Company, or any entity holding Common Shares for or pursuant to the terms of any such plan.
Notwithstanding the foregoing, no Person shall be deemed to be an Acquiring Person as the result of an acquisition of Common Shares by the Company which, by reducing the number of shares outstanding, increases the proportionate number of shares
beneficially owned by such Person to 15% or more of the Common Shares of the Company then outstanding; provided, however, that if a Person shall become the Beneficial Owner of 15% or more of the Common Shares of the Company then
outstanding by reason of share purchases by the Company and shall, after such share purchases by the Company, become the Beneficial Owner of any additional Common Shares of the Company (other than pursuant to a dividend or distribution paid or made
by the Company on the outstanding Common Shares in Common Shares or pursuant to a split or subdivision of the outstanding Common Shares), then such Person shall be deemed to be an Acquiring Person unless upon becoming the Beneficial 







  
 Owner of such additional Common Shares of the Company such Person does not
beneficially own 15% or more of the Common Shares of the Company then outstanding. Notwithstanding the foregoing, (i) if the Company’s 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 paragraph (a), has become such inadvertently (including, without limitation, because (A) such Person was unaware that it beneficially owned a percentage of the Common Shares that
would otherwise cause such Person to be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this paragraph (a), or (B) such Person was aware of the extent of the Common Shares it beneficially owned but had no actual
knowledge of the consequences of such beneficial ownership under this Agreement) and without any intention of changing or influencing control of the Company, and if such Person divested or 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 paragraph (a), then such Person shall not be deemed to be or to have become an “Acquiring Person”
for any purposes of this Agreement including, without limitation Section 1(hh) hereof; and (ii) if, as of the date hereof, any Person is the Beneficial Owner of 15% or more of the Common Shares outstanding, such Person shall not be or become an
“Acquiring Person,” as defined pursuant to the foregoing provisions of this paragraph (a), unless and until such time as such Person shall become the Beneficial Owner of additional Common Shares (other than pursuant to a dividend or
distribution paid or made by the Company on the outstanding Common Shares in Common Shares or pursuant to a split or subdivision of the outstanding Common Shares), unless, upon becoming the Beneficial Owner of such additional Common Shares, such
Person is not then the Beneficial Owner of 15% or more of the Common Shares then outstanding. 
  
 (b)    “Adjustment Fraction” shall have the meaning set forth in Section 11(a)(i) hereof. 
  
 (c)    “Affiliate” and “Associate” shall have the respective meanings ascribed to such
terms in Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in effect on the date of this Agreement. 
  
 (d)    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, for purposes of Section 13(d) of the Exchange Act and Rule 13d-3 thereunder (or any comparable or successor law or regulation); 
  
 (ii)    which such Person or any of such Person’s Affiliates or Associates 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 (other than the Rights), warrants or options, or otherwise; provided, however, that a Person shall not be deemed pursuant to this Section 1(d)(ii)(A) to
be the Beneficial Owner of, or to beneficially own, (1) securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or 

 
 -2- 








  
 any of such Person’s Affiliates or Associates until such tendered securities
are accepted for purchase or exchange, or (2) securities which a Person or any of such Person’s Affiliates or Associates may be deemed to have the right to acquire pursuant to any merger or other acquisition agreement between the Company and
such Person (or one or more of its Affiliates or Associates) if such agreement has been approved by the Board of Directors of the Company prior to there being an Acquiring Person; or (B) the right to vote 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 under this Section 1(d)(ii)(B) if the agreement, arrangement or understanding to vote such security (1)
arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations of the Exchange Act and (2) is not also then
reportable on Schedule 13D under the Exchange Act (or any comparable or successor report); or 
  
 (iii)    which are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) with which such Person or any of such Person’s Affiliates or Associates has any
agreement, arrangement or understanding, whether or not in writing (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities) for the purpose of acquiring,
holding, voting (except to the extent contemplated by the proviso to Section 1(d)(ii)(B)) or disposing of any securities of the Company; provided, however, that in no case shall an officer or director of the Company be deemed (x) the
Beneficial Owner of any securities beneficially owned by another officer or director of the Company solely by reason of actions undertaken by such persons in their capacity as officers or directors of the Company or (y) the Beneficial Owner of
securities held of record by the trustee of any employee benefit plan of the Company or any Subsidiary of the Company for the benefit of any employee of the Company or any Subsidiary of the Company, other than the officer or director, by reason of
any influence that such officer or director may have over the voting of the securities held in the plan. 
  
 (e)    “Business Day” shall mean any day other than a Saturday, Sunday or a day on which banking institutions in New York or California are authorized or obligated by law or executive order
to close. 
  
 (f)    “Close of Business” on any given
date shall mean 5:00 P.M., California time, on such date; provided, however, that if such date is not a Business Day it shall mean 5:00 P.M., California time, on the next succeeding Business Day. 
  
 (g)    “Common Stock Equivalents” shall have the meaning set forth in Section
11(a)(iii) hereof. 
  
 (h)    “Common Shares” when used
with reference to the Company shall mean the shares of Common Stock of the Company, par value at $0.001 per share. Common Shares when used with reference to any Person other than the Company shall mean the capital stock (or equity interest) with the
greatest voting power of such other Person or, if such other Person is a Subsidiary of another Person, the Person or Persons which ultimately control such first-mentioned Person.

 (i)    “Company”
shall mean Centillium Communications, Inc., a Delaware corporation, subject to the terms of Section 13(a)(iii)(C) hereof. 
  
 (j)    “Current Per Share Market Price” of any security (a “Security” for purposes of this definition), for all computations other than those made pursuant to Section
11(a)(iii) hereof, shall mean the average of the daily closing prices per share of such Security for the thirty (30) consecutive Trading Days immediately prior to such date, and for purposes of computations made pursuant to Section 11(a)(iii)
hereof, the Current Per Share Market Price of any Security on any date shall be deemed to be the average of the daily closing prices per share of such Security for the ten (10) consecutive Trading Days immediately prior to 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 (i) a dividend or distribution on such Security
payable in shares of such Security or securities convertible into such shares or (ii) any subdivision, combination or reclassification of such Security, and prior to the expiration of the applicable thirty (30) Trading Day or ten (10) Trading Day
period, after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the Current Per Share Market Price shall be appropriately adjusted to
reflect the current market price per share equivalent of such Security. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Security is not listed or admitted to trading on

selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the Security, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used,
whose determination shall be conclusive for all purposes. If the Preferred Shares are not publicly traded, the Current Per Share Market Price of the Preferred Shares shall be conclusively deemed to be (x) the Current Per Share Market Price of the
Common Shares as determined pursuant to this Section 1(j), as appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof, multiplied by (y) 1,000. If the Security is not 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 of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall
be conclusive for all purposes.

 Section 3.    Issuance of Rights Certificates. 

 
 (a)    Until the Distribution Date, (i) the Rights will be evidenced (subject to the

the right to receive Rights Certificates will be transferable only in connection with the transfer of Common Shares. Until the earlier of the Distribution Date or the Expiration Date, the surrender for transfer of certificates for Common Shares

Rights Certificates and may be transferred by the transfer of the Rights Certificates as permitted hereby, separately and apart from any transfer of Common Shares, and the holders of such Rights Certificates as listed in the records of the Company
or any transfer agent or registrar for the Rights shall be the record holders thereof. 

 
 -7- 








  
 (b)    On the Record Date or as soon as
practicable thereafter, the Company will send a copy of 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’s transfer agent and registrar. 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 the Summary of Rights. 
  
 (c)    Unless the
Company’s Board of Directors by resolution adopted at or before the time of the issuance of any Common Shares after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date (or, in certain circumstances provided
in Section 22 hereof, after the Distribution Date) specifies to the contrary, Rights shall be issued in respect of all Common Shares that are so issued, and Certificates representing such Common Shares shall also be deemed to be certificates for
Rights, and shall bear the following legend: 
  
 THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER HEREOF TO
CERTAIN RIGHTS AS SET FORTH IN A PREFERRED STOCK RIGHTS AGREEMENT BETWEEN CENTILLIUM COMMUNICATIONS, INC. AND MELLON INVESTOR SERVICES LLC, AS THE RIGHTS AGENT, DATED AS OF DECEMBER 30, 2002 (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 CENTILLIUM COMMUNICATIONS, INC. UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, SUCH RIGHTS WILL BE EVIDENCED BY SEPARATE
CERTIFICATES AND WILL NO LONGER BE EVIDENCED BY THIS CERTIFICATE. THE COMPANY WILL MAIL TO THE HOLDER OF THIS CERTIFICATE A COPY OF THE RIGHTS AGREEMENT WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN REQUEST THEREFOR. UNDER CERTAIN CIRCUMSTANCES SET
FORTH IN THE RIGHTS AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), WHETHER CURRENTLY HELD BY OR ON BEHALF OF
SUCH PERSON OR BY ANY SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID. 
  
 With respect to such certificates containing
the foregoing legend, until the earlier of the Distribution Date or the Expiration Date, the Rights associated with the Common 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. 
  
 (d)    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


 
 -8- 








  
 Shares shall be deemed canceled and retired so that the Company shall not be
entitled to exercise any Rights associated with the Common Shares that are no longer outstanding. 
  
 Section
4.    Form of Rights Certificates. 
  
 (a)    The
Rights Certificates (and the forms of election to purchase Common Shares and of assignment to be printed on the reverse thereof) shall be substantially in the form of 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, which do not affect the rights, duties or responsibilities of the Rights Agent, and which are not inconsistent with the provisions of this Agreement, or
as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or a national market system, on which the Rights may from time to time be listed or
included, or to conform to usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated as of the Record Date (or in the case of Rights issued with respect to Common Shares
issued by the Company after the Record Date, as of the date of issuance of such Common Shares) and on their face shall entitle the holders thereof to purchase such number of one-thousandths (0.001) of a Preferred Share as shall be set forth therein
at the price set forth therein (such exercise price per one one-thousandth (0.001) of a Preferred Share being hereinafter referred to as the “Exercise Price” and the aggregate Exercise Price of all Preferred Shares issuable
upon exercise of one Right being hereinafter referred to as the “Total Exercise Price”), but the number and type of securities purchasable upon the exercise of each Right and the Exercise 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 Post-Event Transferee, (iii) a Pre-Event Transferee or (iv) any subsequent transferee
receiving transferred Rights from a Post-Event Transferee or a Pre-Event Transferee, either directly or through one or more intermediate transferees, and any Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer,
exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain (to the extent feasible) the following legend: 
  
 THE RIGHTS REPRESENTED BY THIS RIGHTS CERTIFICATE ARE OR WERE BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN ACQUIRING PERSON OR AN AFFILIATE OR ASSOCIATE OF AN ACQUIRING PERSON (AS SUCH TERMS ARE
DEFINED IN THE PREFERRED STOCK RIGHTS AGREEMENT BETWEEN CENTILLIUM COMMUNICATIONS, INC. AND MELLON INVESTOR SERVICES LLC, AS THE RIGHTS AGENT, DATED AS OF DECEMBER 30, 2002 (THE “RIGHTS AGREEMENT”)). ACCORDINGLY, THIS RIGHTS CERTIFICATE
AND THE RIGHTS REPRESENTED HEREBY MAY BECOME NULL AND VOID IN THE CIRCUMSTANCES SPECIFIED IN SECTION 7(e) OF THE RIGHTS AGREEMENT.

 Section 5.    Countersignature and Registration.

  
 (a)    The Rights Certificates shall be executed on behalf of the Company by
its Chairman of the Board, its Chief Executive Officer, its Chief Financial Officer, its President or any Vice President, either manually or by facsimile signature, and by the Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature, and shall have affixed thereto the Company’s seal (if any) or a facsimile thereof. The Rights Certificates shall be manually 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 on behalf of the Company had not ceased to be such officer of the
Company; and any Rights Certificate may be signed on behalf of the Company by any person who, at the actual date of the execution of such Rights Certificate, shall be a proper officer of the Company to sign such Rights Certificate, although at the
date of the execution of this Agreement any such person was not such an officer. 
  
 (b)    Following the Distribution Date and receipt by the Rights Agent of all relevant information, the Rights Agent will keep or cause to be kept, at its office designated for such purposes, books for
registration and transfer of the Rights Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Rights Certificates, the number of Rights evidenced on its face by each of the Rights Certificates
and the date of each of the Rights Certificates. 
  
 Section 6.    Transfer, Split Up,
Combination and Exchange of Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. 
  
 (a)    Subject to the provisions of Sections 7(e), 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 Expiration Date, any Rights
Certificate or Rights Certificates 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-thousandths (0.001) of a Preferred Share
(or, following a Triggering Event, other securities, cash or other assets, as the case may be) as the Rights Certificate or Rights Certificates surrendered then entitled such holder to purchase. Any registered holder desiring to transfer, split up,
combine or exchange any Rights Certificate or Rights Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Rights Certificates to be transferred, split up, combined or exchanged
at the office of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Rights Certificate until the registered
holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial
Owner) or Affiliates or Associates thereof as the Company shall reasonably request. Thereupon the Rights Agent shall, 

 
 -10- 








  
 subject to Sections 7(e), 14 and 24 hereof, countersign and deliver to the Person
entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment from the registered holder of a sum sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Rights Certificates. The Rights Agent shall have no duty or obligation under this Section unless and until it is satisfied that all such taxes and/or governmental 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 countersignature and delivery to the registered holder in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated. 
  
 Section 7.    Exercise of Rights; Exercise Price; Expiration Date of Rights. 
  
 (a)    Subject to Sections 7(e), 23(b) and 24(b) hereof, the registered holder of any Rights Certificate may exercise the Rights
evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date and prior to the Close of Business on the Expiration Date by surrender of the Rights Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the Exercise Price for each one-thousandth (0.001) of a Preferred Share (or, following a
Triggering Event, other securities, cash or other assets as the case may be) as to which the Rights are exercised. 
  
 (b)    The Exercise Price for each one-thousandth (0.001) of a Preferred Share issuable pursuant to the 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 paragraph (c) below. 
  
 (c)    Upon receipt of a Rights Certificate representing exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Exercise Price for the number of one-thousandths (0.001) of a Preferred Share (or, following a Triggering Event, other securities, cash or other assets as the case may be) to be purchased and an amount equal to any
applicable tax or governmental charge required to be paid by the holder of such Rights Certificate in accordance with Section 9(e) hereof, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition from any
transfer agent of the Preferred Shares (or make available, if the Rights Agent is the transfer agent for the Preferred Shares) a certificate or certificates for the number of one-thousandths (0.001) of a Preferred Share (or, following a Triggering
Event, other securities, cash or other assets as the case may be) to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests or (B) if the Company shall have elected to deposit the total number
of one-thousandths (0.001) of a Preferred Share (or, following a Triggering Event, other securities, cash or other assets as the case may be) 

 
 -11- 








  
 issuable upon exercise of the Rights hereunder with a depository agent,
requisition from the depository agent depository receipts representing such number of one-thousandths (0.001) of a Preferred Share (or, following a Triggering Event, other securities, cash or other assets as the case may be) as are to be purchased
(in which case certificates for the Preferred Shares (or, following a Triggering Event, other securities, cash or other assets as the case may be) represented by such receipts shall be deposited by the transfer agent with the depository agent) and
the Company hereby directs the depository agent to comply with such request, (ii) when appropriate, requisition from the Company 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 depository receipts, cause the same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder and (iv) when
appropriate, after receipt thereof, deliver such cash to or upon the order of the registered holder of such Rights Certificate. The payment of the Exercise Price (as such amount may be reduced (including to zero) pursuant to Section 11(a)(iii)
hereof) and an amount equal to any applicable transfer tax required to be paid by the holder of such Rights Certificate in accordance with Section 9(e) hereof, may be made in cash or by certified bank check, cashier’s check or bank draft
payable to the order of the Company. In the event that the Company is obligated to issue securities of the Company other than Preferred Shares, pay cash and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all
arrangements necessary so that such other securities, cash and/or other property are available for distribution by the Rights Agent, if and when necessary to comply with this Agreement. 
  
 (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 or her duly authorized assigns, subject to the provisions of Section 6 and
Section 14 hereof. 
  
 (e)    Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Triggering Event, any Rights beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person becomes such (a “Post-Event Transferee”), (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person
with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Company’s Board of Directors has determined is part of a plan, arrangement or understanding
which has as a primary purpose or effect the avoidance of this Section 7(e) (a “Pre-Event Transferee”) or (iv) any subsequent transferee receiving transferred Rights from a Post-Event Transferee or a Pre-Event Transferee,
either directly or through one or more intermediate transferees, shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this
Agreement or otherwise. The Company shall notify the Rights Agent when this Section 7(e) and Section 4(b) applies and shall use all reasonable efforts to ensure 

 
 -12- 








  
 that the provisions of this Section 7(e) and Section 4(b) hereof are complied
with, but neither the Rights Agent nor the Company shall have any liability to any holder of Rights Certificates or to any other Person as a result of the Company’s failure to make any determinations with respect to an Acquiring Person or any
of such Acquiring Person’s Affiliates, Associates or transferees hereunder. 
  
 (f)    Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any
purported exercise as set forth in Section 7 unless such registered holder shall, in addition to having complied with the requirements of subsection 7(a), have (i) properly completed and signed the certificate contained in the form of election to
purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the
Company and the Rights Agent shall reasonably request. 
  
 Section 8.    Cancellation and
Destruction of Rights Certificates.    All Rights Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to
the Rights Agent for cancellation or in canceled form, or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this
Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any Rights Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The
Rights Agent shall deliver all canceled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such canceled Rights Certificates, and in such case shall deliver a certificate evidencing the destruction thereof
to the Company. 
  
 Section 9.    Reservation and Availability of Preferred Shares.

  
 (a)    The Company covenants and agrees that it will use its best efforts to
cause to be reserved and kept available out of its authorized and unissued Preferred Shares not reserved for another purpose (and, following the occurrence of a Triggering Event, out of its authorized and unissued Common Shares and/or other
securities), the number of Preferred Shares (and, following the occurrence of the Triggering Event, Common Shares and/or other securities) that will be sufficient to permit the exercise in full of all outstanding Rights in accordance with this
Agreement. 
  
 (b)    If the Company shall hereafter list any of its Preferred
Shares on a national securities exchange, then so long as the Preferred Shares (and, following the occurrence of a Triggering Event, Common Shares and/or other securities) issuable and deliverable upon exercise of the Rights may be listed on such
exchange, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable (but only to the extent that the Company’s Board of Directors determines that it is reasonably likely that the Rights will be
exercised), all shares reserved for such issuance to be listed on such exchange upon official notice of issuance upon such exercise. 
  
 (c)    The Company shall use its best efforts to (i) file, as soon as practicable following the earliest date after the first occurrence of a Triggering Event in which the
consideration 

 
 -13- 








  
 to be delivered by the Company upon exercise of the Rights is described in
Section 11(a)(ii) or Section 11(a)(iii) hereof, or as soon as is required by law following the Distribution Date, as the case may be, a registration statement under the Securities Act with respect to the securities purchasable upon exercise of the
Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the
requirements of the Securities Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities and (B) the date of expiration of the Rights. The Company may temporarily suspend, for a period not to exceed
ninety (90) days after the date set forth in clause (i) of the first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating, and notify the Rights Agent, that the exercisability of the Rights has been temporarily suspended, as well as a public announcement and notification to the Rights Agent at such time
as the suspension is no longer in effect. 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. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction, unless the requisite qualification in such jurisdiction shall have been obtained, or an exemption therefrom shall
be available, and until a registration statement has been declared and remains effective. 
  
 (d)    The Company covenants and agrees that it will take all such action as may be necessary to ensure that all Preferred Shares (or other securities of the Company) delivered upon exercise of Rights shall, at
the time of delivery of the certificates for such securities (subject to payment of the Exercise Price), be duly and validly authorized and issued and fully paid and nonassessable. 
  
 (e)    The Company further covenants and agrees that it will pay when due and payable any and all taxes and charges which may be payable
in respect of the original issuance or delivery of the Rights Certificates or of any Preferred Shares (or other securities of the Company) upon the exercise of Rights. The Company shall not, however, be required to pay any tax or charge which may be
payable in respect of any transfer or delivery of Rights Certificates to a Person other than, or the issuance or delivery of certificates or depository receipts for the Preferred Shares (or other securities of the Company) 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 depository receipts for Preferred Shares (or other securities of the Company) upon the exercise of any
Rights until any such tax and charge shall have been paid (any such tax and charge being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax
or charge is due. 
  
 Section 10.    Record Date.    Each Person in
whose name any certificate for a number of one-thousandths (0.001) of a Preferred Share (or other securities of the Company) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of Preferred
Shares (or other securities of the Company) represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and 

 
 -14- 








  
 payment of the Total Exercise Price with respect to which the Rights have been
exercised (and any applicable transfer taxes and charges) was made; provided, however, that if the date of such surrender and payment is a date upon which the 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 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 other securities of the Company) 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 Exercise Price, Number of Shares or Number of Rights.    The Exercise Price, the number and kind of shares or other property
covered by each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11. 
  
 (a)    (i)    Anything in this Agreement to the contrary notwithstanding, in the event that 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 (by reverse stock split or otherwise) 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), then, in each
such event, except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the Exercise Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification
shall be adjusted so that the Exercise Price thereafter shall equal the result obtained by dividing the Exercise Price in effect immediately prior to such time by a fraction (the “Adjustment Fraction”), the numerator of which
shall be the total number of Preferred Shares (or shares of capital stock issued in such reclassification of the Preferred Shares) outstanding immediately following such time and the denominator of which shall be the total number of Preferred Shares
outstanding immediately prior to such time; 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 such Right; and (2) the number of one-thousandths (0.001) of a Preferred Share (or share of such other capital stock) issuable upon the exercise of each Right shall equal the number of one-thousandths (0.001) of a Preferred
Share (or share of such other capital stock) as was issuable upon exercise of a Right immediately prior to the occurrence of the event described in clauses (A)-(D) of this Section 11(a)(i), multiplied by the Adjustment Fraction; provided, however,
that, no such adjustment shall be made pursuant to this Section 11(a)(i) to the extent that there shall have simultaneously occurred an event described in clause (A), (B), (C) or (D) of Section 11(n) with a proportionate adjustment being made
thereunder. Each Common Share that shall become outstanding after an adjustment has been made pursuant to this Section 11(a)(i) shall have associated with it the number of Rights, exercisable at the Exercise Price and for the number of
one-thousandths (0.001) of a Preferred Share (or shares of such other capital stock) as one Common Share has associated with it immediately following the adjustment made pursuant to this Section 11(a)(i). 

 
 -15- 








  
 (ii)    Subject to Section 24 of this
Agreement, in the event that a Triggering Event shall have occurred, then promptly following such Triggering Event each holder of a Right, except as provided in Section 7(e) hereof, shall thereafter have the right to receive for each Right, upon
exercise thereof in accordance with the terms of this Agreement and payment of the Exercise Price in effect immediately prior to the occurrence of the Triggering Event, in lieu of a number of one-thousandths (0.001) of a Preferred Share, such number
of Common Shares of the Company as shall equal the quotient obtained by dividing (A) the product obtained by multiplying (1) the Exercise Price in effect immediately prior to the occurrence of the Triggering Event by (2) the number of
one-thousandths (0.001) of a Preferred Share for which a Right was exercisable (or would have been exercisable if the Distribution Date had occurred) immediately prior to the first occurrence of a Triggering Event, by (B) fifty percent (50%) of the
Current Per Share Market Price for Common Shares on the date of occurrence of the Triggering Event; provided, however, that the Exercise Price and the number of Common Shares of the Company so receivable upon exercise of a Right shall
be subject to further adjustment as appropriate in accordance with Section 11(e) hereof to reflect any events occurring in respect of the Common Shares of the Company after the occurrence of the Triggering Event. 
  
 (iii)    In lieu of issuing Common Shares in accordance with Section 11(a)(ii) hereof, the Company
may, if the Company’s Board of Directors determines that such action is necessary or appropriate and not contrary to the interest of holders of Rights and, in the event that the number of Common Shares which are authorized by the Company’s
Certificate of Incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights are not sufficient to permit the exercise in full of the Rights, or if any necessary regulatory approval for such issuance
has not been obtained by the Company, the Company shall: (A) determine the excess of (1) the value of the Common Shares issuable upon the exercise of a Right (the “Current Value”) over (2) the Exercise Price (such excess,
the “Spread”) and (B) with respect to each Right, make adequate provision to substitute for such Common Shares, upon exercise of the Rights, (1) cash, (2) a reduction in the Exercise Price, (3) other equity securities of the
Company (including, without limitation, shares or units of shares of any series of preferred stock which the Company’s Board of Directors has deemed to have the same value as Common Shares (such shares or units of shares of preferred stock are
herein called “Common Stock Equivalents”)), except to the extent that the Company has not obtained any necessary stockholder or regulatory approval for such issuance, (4) debt securities of the Company, except to the extent
that the Company has not obtained any necessary stockholder or regulatory approval for such issuance, (5) other assets or (6) any combination of the foregoing, having an aggregate value equal to the Current Value, where such aggregate value has been
determined by the Company’s Board of Directors based upon the advice of a nationally recognized investment banking firm selected by the Company’s Board of Directors; provided, however, that if the Company shall not have made
adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the later of (x) the first occurrence of a Triggering Event and (y) the date on which the Company’s right of redemption pursuant to Section 23(a)
expires (the later of (x) and (y) being referred to herein as the “Section 11(a)(ii) 

 
 -16- 








  
 Trigger Date”), then the Company shall be obligated to
deliver, upon the surrender for exercise of a Right and without requiring payment of the Exercise Price, Common Shares (to the extent available), except to the extent that the Company has not obtained any necessary stockholder or regulatory approval
for such issuance, and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If the Company’s Board of Directors shall determine in good faith that it is likely that sufficient additional Common Shares
could be authorized for issuance upon exercise in full of the Rights or that any necessary regulatory approval for such issuance will be obtained, the thirty (30) day period set forth above may be extended to the extent necessary, but not more than
ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares or take action to obtain such regulatory approval (such period, as it may be extended,
the “Substitution Period”). To the extent that the Company determines that some action need be taken pursuant to the first and/or second sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to Section
7(e) hereof, that such action shall apply uniformly to all outstanding Rights and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares, to take any
action to obtain any required regulatory approval and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall promptly
notify the Rights Agent thereof and shall issue a public announcement (with prompt notice thereof to the Rights Agent) stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement (with prompt notice
thereof to the Rights Agent) at such time as the suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of the Common Shares shall be the Current Per Share Market Price of the Common Shares on the Section 11(a)(ii)
Trigger Date and the value of any Common Stock Equivalent shall be deemed to have the same value as the Common Shares on such date. 
  
 (b)    In case the Company shall, at any time after the date of this Agreement, fix a record date for the issuance of rights, options or warrants to all holders of Preferred Shares
entitling such holders (for a period expiring within forty-five (45) calendar days after such record date) to subscribe for or purchase Preferred Shares or Equivalent Shares or securities convertible into Preferred Shares or Equivalent Shares at a
price per share (or having a conversion price per share, if a security convertible into Preferred Shares or Equivalent Shares) less than the then Current Per Share Market Price of the Preferred Shares or Equivalent Shares on such record date, then,
in each such case, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of Preferred
Shares and Equivalent Shares (if any) outstanding on such record date, plus the number of Preferred Shares or Equivalent Shares, as the case may be, which the aggregate offering price of the total number of Preferred Shares or Equivalent Shares, as
the case may be, to be offered or issued (and/or the aggregate initial conversion price of the convertible securities to be offered or issued) would purchase at such current market price, and the denominator of which shall be the number of Preferred
Shares and Equivalent Shares (if any) outstanding on such record date, plus the number of additional Preferred Shares or Equivalent Shares, as the case may be, 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 

 
 -17- 








  
 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 Company’s Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive and binding on the Rights Agent and the holders of the Rights for all purposes. Preferred
Shares and Equivalent 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 Exercise Price shall be adjusted to be the Exercise Price which would then be in effect if such record date had not been fixed. 
  
 (c)    In case the Company shall, at any time after the date of this Agreement, fix a record date for the making of a distribution to
all holders of the Preferred Shares or of any class or series of Equivalent Shares (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving Person) of evidences of
indebtedness or assets (other than a regular quarterly cash dividend, if any, or a dividend payable in Preferred Shares) or subscription rights, options or warrants (excluding those referred to in Section 11(b)), then, in each such case, the
Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the Current Per Share Market Price of a
Preferred Share or an Equivalent Share on such record date, less the fair market value per Preferred Share or Equivalent Share (as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be conclusive for all purposes) of the portion of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to a Preferred Share or
Equivalent Share, as the case may be, and the denominator of which shall be such Current Per Share Market Price of a Preferred Share or Equivalent Share on such record date; provided, however, that in no event shall the consideration
to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon exercise of one Right. Such adjustments shall be made successively whenever such a record date is fixed, and
in the event that such distribution is not so made, the Exercise Price shall be adjusted to be the Exercise Price which would have been in effect if such record date had not been fixed. 
  
 (d)    Anything herein to the contrary notwithstanding, no adjustment in the Exercise Price shall be required unless such adjustment
would require an increase or decrease of at least one percent (1%) of the Exercise Price; provided, however, that any adjustments which by reason of this Section 11(d) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest ten-thousandth (0.0001) of a Common Share or other share or one hundred-thousandth (0.00001) of a Preferred Share, as
the case may be. Notwithstanding the first sentence of this Section 11(d), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three (3) years from the date of the transaction which requires such adjustment or
(ii) the Expiration Date. 

 
 -18- 








  
 (e)    If as a result of an adjustment made
pursuant to Section 11(a) or Section 13(a) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock other than Preferred Shares, thereafter the number of such other shares so receivable upon
exercise of any Right and, if required, the Exercise Price thereof, shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Shares contained in
Sections 11(a), 11(b), 11(c), 11(d), 11(g), 11(h), 11(i), 11(j), 11(k) and 11(l), 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. 
  
 (f)    All Rights originally issued by the Company subsequent to any adjustment made to the Exercise
Price hereunder shall evidence the right to purchase, at the adjusted Exercise Price, the number of one-thousandths (0.001) of a Preferred Share purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment
as provided herein. 
  
 (g)    Unless the Company shall have exercised its
election as provided in Section 11(h), upon each adjustment of the Exercise Price as a result of the calculations made in Section 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the
right to purchase, at the adjusted Exercise Price, that number of Preferred Shares (calculated to the nearest one hundred-thousandth (0.00001) of a share) obtained by (i) multiplying (x) the number of Preferred Shares covered by a Right immediately
prior to this adjustment, by (y) the Exercise Price in effect immediately prior to such adjustment of the Exercise Price, and (ii) dividing the product so obtained by the Exercise Price in effect immediately after such adjustment of the Exercise
Price. 
  
 (h)    The Company may elect on or after the date of any adjustment of
the Exercise Price as a result of the calculations made in Section 11(b) or (c) to adjust the number of Rights, in substitution for any adjustment in the number of Preferred Shares 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-thousandths (0.001) 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 hundred-thousandth (0.00001)) obtained by dividing the Exercise Price in effect immediately prior to adjustment of the Exercise Price by the
Exercise Price in effect immediately after adjustment of the Exercise Price. The Company shall make a public announcement and promptly notify 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 Exercise Price is adjusted or any day thereafter, but, if any Rights Certificates have been issued, shall be at least ten
(10) days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(h), 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 

 
 -19- 








  
 prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may
bear, at the option of the Company, the adjusted Exercise Price) and shall be registered in the names of the holders of record of Rights Certificates on the record date specified in the public announcement. 
  
 (i)    Irrespective of any adjustment or change in the Exercise Price or the number of Preferred
Shares issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price per one one-thousandth (0.001) of a Preferred Share and the number of one-thousandths (0.001) of a
Preferred Share which were expressed in the initial Rights Certificates issued hereunder. 
  
 (j)    Before taking any action that would cause an adjustment reducing the Exercise Price below the par or stated value, if any, of the number of one-thousandths (0.001) of a Preferred Share 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 as fully paid and nonassessable shares such number of one-thousandths
(0.001) of a Preferred Share at such adjusted Exercise Price. 
  
 (k)    In any
case in which this Section 11 shall require that an adjustment in the Exercise 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 number of one-thousandths (0.001) of a Preferred Share and other capital stock or securities of the Company, if any, issuable upon such exercise
over and above the number of one-thousandths (0.001) of a Preferred Share and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment;
provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional shares (fractional or otherwise) upon the occurrence of the
event requiring such adjustment. 
  
 (l)    Anything in this Section 11 to the
contrary notwithstanding, prior to the Distribution Date, the Company shall be entitled to make such adjustments in the Exercise 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 (i) consolidation or subdivision of the Preferred or Common Shares, (ii) issuance wholly for cash of any Preferred or Common Shares at less than the current market price, (iii) issuance
wholly for cash of Preferred or Common Shares or securities which by their terms are convertible into or exchangeable for Preferred or Common Shares, (iv) stock dividends or (v) issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Company to holders of its Preferred or Common Shares shall not be taxable to such stockholders. 
  
 (m)    The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted by Sections 23, 24 or 27 hereof, take (or permit to be taken) any action if at the time such
action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights. 

 
 -20- 








  
 (n)    In the event that the Company shall at
any time after the date of this Agreement (A) declare a dividend on the Common Shares payable in Common Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding Common Shares (by reverse stock split or otherwise) into a
smaller number of Common Shares, or (D) issue any shares of its capital stock in a reclassification of the Common Shares (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or
surviving Person), then, in each such event, except as otherwise provided in this Section 11(a) and Section 7(e) hereof: (1) each Common Share (or shares of capital stock issued in such reclassification of the Common Shares) outstanding immediately
following such time shall have associated with it the number of Rights as were associated with one Common Share immediately prior to the occurrence of the event described in clauses (A)-(D) above; (2) the Exercise Price in effect at the time of the
record date for such dividend or of the effective date of such subdivision, combination or reclassification shall be adjusted so that the Exercise Price thereafter shall equal the result obtained by multiplying the Exercise Price in effect
immediately prior to such time by a fraction, the numerator of which shall be the total number of Common Shares outstanding immediately prior to the event described in clauses (A)-(D) above, and the denominator of which shall be the total number of
Common Shares outstanding immediately after such event; 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 such Right; and (3) the number of one-thousandths (0.001) of a Preferred Share (or shares of such other capital stock) issuable upon the exercise of each Right outstanding after such event shall equal the number of
one-thousandths (0.001) of a Preferred Share (or shares of such other capital stock) as were issuable with respect to one Right immediately prior to such event. Each Common Share that shall become outstanding after an adjustment has been made
pursuant to this Section 11(n) shall have associated with it the number of Rights, exercisable at the Exercise Price and for the number of one-thousandths (0.001) of a Preferred Share (or shares of such other capital stock) as one Common Share has
associated with it immediately following the adjustment made pursuant to this Section 11(n). If an event occurs which would require an adjustment under both this Section 11(n) and Section 11(a)(ii) hereof, the adjustment provided for in this Section
11(n) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii) hereof. 
  
 Section 12.    Certificate of Adjusted Exercise Price or Number of Shares.    Whenever an adjustment is made as provided in Sections 11 or 13 hereof, the Company shall promptly (a)
prepare a certificate setting forth such adjustment and a brief statement of the facts and computations accounting for such adjustment, (b) file with the Rights Agent and with each transfer agent for 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 26 hereof. Notwithstanding the foregoing sentence, the failure of the Company to make such certification or give such notice shall not affect the
validity of such adjustment or the force or effect of the requirement for such adjustment. 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. 

 
 -21- 








  
 Section 13.    Consolidation, Merger or Sale or Transfer
of Assets or Earning Power. 
  
 (a)    In the event that, following a
Triggering Event, directly or indirectly: 
  
 (i)    the Company shall
consolidate with, or merge with and into, any other Person (other than a wholly-owned Subsidiary of the Company in a transaction the principal purpose of which is to change the state of incorporation of the Company and which complies with Section
11(m) hereof); 
  
 (ii)    any Person shall consolidate with the Company, or
merge with and into the Company and the Company shall be the continuing or surviving Person of such consolidation or merger and, in connection with such merger, all or part of the Common Shares shall be changed into or exchanged for stock or other
securities of any other Person (or the Company); or 
  
 (iii)    the Company
shall sell or otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise transfer), in one or more transactions, assets or earning power aggregating fifty percent (50%) or more of the assets or earning power of the Company and
its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company or one or more of its wholly owned Subsidiaries in one or more transactions, each of which individually (and together) complies with Section 11(m) hereof),

  
 then, concurrent with and in each such case, 
  
 (A)    each holder of a Right (except as provided in Section 7(e) hereof) shall thereafter have the
right to receive, upon the exercise thereof at a price equal to the Total Exercise Price applicable immediately prior to the occurrence of the Section 13 Event in accordance with the terms of this Agreement, such number of validly authorized and
issued, fully paid, nonassessable and freely tradeable Common Shares of the Principal Party (as hereinafter defined), free of any liens, encumbrances, rights of first refusal or other adverse claims, as shall be equal to the result obtained by
dividing such Total Exercise Price by an amount equal to fifty percent (50%) of the Current Per Share Market Price of the Common Shares of such Principal Party on the date of consummation of such Section 13 Event, provided, however,
that the Exercise Price and the number of Common Shares of such Principal Party so receivable upon exercise of a Right shall be subject to further adjustment as appropriate in accordance with Section 11(e) hereof; 
  
 (B)    such Principal Party shall thereafter be liable for, and shall assume, by virtue of such
Section 13 Event, all the obligations and duties of the Company pursuant to this Agreement; 
  
 (C)    the term “Company” shall thereafter be deemed to refer to such Principal Party, it being specifically intended that the provisions of Section 11 hereof shall apply only to such Principal Party
following the first occurrence of a Section 13 Event; 

 
 -22- 








  
 (D)    such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of its Common Shares) in connection with the consummation of any such transaction as may be necessary to ensure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to its Common Shares thereafter deliverable upon the exercise of the Rights; and 
  
 (E)    upon the subsequent occurrence of any consolidation, merger, sale or transfer of assets or other extraordinary transaction in respect of such Principal Party, each holder of
a Right shall thereupon be entitled to receive, upon exercise of a Right and payment of the Total Exercise Price as provided in this Section 13(a), such cash, shares, rights, warrants and other property which such holder would have been entitled to
receive had such holder, at the time of such transaction, owned the Common Shares of the Principal Party receivable upon the exercise of such Right pursuant to this Section 13(a), and such Principal Party shall take such steps (including, but not
limited to, reservation of shares of stock) as may be necessary to permit the subsequent exercise of the Rights in accordance with the terms hereof for such cash, shares, rights, warrants and other property. 
  
 (F)    For purposes hereof, the “earning power” of the Company and its Subsidiaries shall
be determined in good faith by the Company’s Board of Directors on the basis of the operating income of each business operated by the Company and its Subsidiaries during the three fiscal years preceding the date of such determination (or, in
the case of any business not operated by the Company or any Subsidiary during three full fiscal years preceding such date, during the period such business was operated by the Company or any Subsidiary). 
  
 (b)    For purposes of this Agreement, the term “Principal Party” shall mean:

  
 (i)    in the case of any transaction described in clause (i) or (ii) of
Section 13(a) hereof: (A) the Person that is the issuer of the securities into which the Common Shares are converted in such merger or consolidation, or, if there is more than one such issuer, the issuer the Common Shares of which have the greatest
aggregate market value of shares outstanding, or (B) if no securities are so issued, (x) the Person that is the other party to the merger, if such Person survives said merger, or, if there is more than one such Person, the Person the Common Shares
of which have the greatest aggregate market value of shares outstanding or (y) if the Person that is the other party to the merger does not survive the merger, the Person that does survive the merger (including the Company if it survives) or (z) the
Person resulting from the consolidation; and 
  
 (ii)    in the case of any
transaction described in clause (iii) of Section 13(a) hereof, the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions, or, if more than one Person that is a
party to such transaction or transactions receives the same portion of the assets or earning power so transferred and each such portion would, were it not for the other equal portions, constitute the greatest portion of the assets or earning power
so transferred, or if the Person receiving the greatest portion of the assets or earning power cannot be determined, whichever of such Persons is the issuer of Common Shares having the greatest aggregate market value of shares outstanding; provided
that in any such case described in the foregoing clause (b)(i) or (b)(ii), if the Common Shares of such
 

 
 -23- 








 
Person are not at such time or have not been continuously over the preceding 12-month period registered under Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so registered, the term “Principal Party” shall refer to such other Person, or (2) if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of which are and have been so registered, the term “Principal Party” shall refer to whichever of such Persons is the issuer of Common Shares having the greatest aggregate market value of shares outstanding, or (3) if 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 clauses (1) and (2) above shall apply to each of the owners having an
interest in the venture as if the Person owned by the joint venture was a Subsidiary of both or all of such joint venturers, and the Principal Party in each such case shall bear the obligations set forth in this Section 13 in the same ration as its
interest in such Person bears to the total of such interests. 
  
 (c)    The
Company shall not consummate any Section 13 Event unless the Principal Party shall have a sufficient number of authorized Common Shares that have not been issued or reserved for issuance to permit the exercise in full of the Rights in accordance
with this Section 13 and unless prior thereto the Company and such issuer shall have executed and delivered to the Rights Agent a supplemental agreement confirming that such Principal Party shall, upon consummation of such Section 13 Event, assume
this Agreement in accordance with Sections 13(a) and 13(b) hereof, that all rights of first refusal or preemptive rights in respect of the issuance of Common Shares of such Principal Party upon exercise of outstanding Rights have been waived, that
there are no 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 and that such transaction shall not result in a default by such Principal Party under this Agreement, and further providing that, as soon as practicable after the date of such Section 13 Event, such Principal Party will: 

 
 (i)    prepare and file a registration statement under the Securities Act with respect to
the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, use its best efforts to cause such registration statement to become effective as soon as practicable after such filing and use its best efforts to cause
such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Expiration Date, and similarly comply with applicable state securities laws; 
  
 (ii)    use its best efforts to list (or continue the listing of) the Rights and the securities
purchasable upon exercise of the Rights on a national securities exchange or to meet the eligibility requirements for quotation on Nasdaq and list (or continue the listing of) the Rights and the securities purchasable upon exercise of the Rights on
Nasdaq; and 
  
 (iii)    deliver to holders of the Rights historical financial
statements for such Principal Party that comply in all respects with the requirements for registration on Form 10 (or any successor form) under the Exchange Act. 

 
 -24- 








  
 In the event that at any time after the occurrence of a
Triggering Event some or all of the Rights shall not have been exercised at the time of a transaction described in this Section 13, the Rights which have not theretofore been exercised shall thereafter be exercisable in the manner described in
Section 13(a) (without taking into account any prior adjustment required by Section 11(a)(ii)). 
  
 (d)    In case the “Principal Party” for purposes of Section 13(b) hereof has provision in any of its authorized securities or in its certificate of incorporation or by-laws or other instrument governing
its corporate affairs, which provision would have the effect of (i) causing such Principal Party to issue (other than to holders of Rights pursuant to Section 13 hereof), in connection with, or as a consequence of, the consummation of a Section 13
Event, Common Shares or Equivalent Shares of such Principal Party at less than the then Current Per Share Market Price thereof or securities exercisable for, or convertible into, Common Shares or Equivalent Shares of such Principal Party at less
than such then Current Per Share Market Price, or (ii) providing for any special payment, tax or similar provision in connection with the issuance of the Common Shares of such Principal Party pursuant to the provisions of Section 13 hereof, then, in
such event, the Company hereby agrees with each holder of Rights that it shall not consummate any such transaction unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental
agreement providing that the provision in question of such Principal Party shall have been canceled, waived or amended, or that the authorized securities shall be redeemed, so that the applicable provision will have no effect in connection with or
as a consequence of, the consummation of the proposed transaction. 
  
 (e)    The
Company covenants and agrees that it shall not, at any time after the Distribution Date, effect or permit to occur any Section 13 Event, if (i) at the time or immediately after such Section 13 Event there are any rights, warrants or other
instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights, (ii) prior to, simultaneously with or immediately after such Section 13
Event, the stockholders of the Person who constitutes, or would constitute, the “Principal Party” for purposes of Section 13(b) hereof shall have received a distribution of Rights previously owned by such Person or any of its Affiliates or
Associates or (iii) the form or nature of organization of the Principal Party would preclude or limit the exercisability of the Rights. 
  
 (f)    The provisions of this Section 13 shall similarly apply to successive mergers or consolidations or sales or other 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 that evidence
fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Rights Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of
the current market value of a whole Right. For 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, as determined pursuant to the second sentence of Section 1(j) hereof. 

 
 -25- 








  
 (b)    The Company shall not be required to
issue fractions of Preferred Shares (other than fractions that are integral multiples of one one-thousandth (0.001) of a Preferred Share) upon exercise of the Rights or to distribute certificates which evidence fractional Preferred Shares (other
than fractions that are integral multiples of one one-thousandth (0.001) of a Preferred Share). Interests in fractions of Preferred Shares in integral multiples of one one-thousandth (0.001) of a Preferred Share may, at the election of the Company,
be evidenced by depository receipts, pursuant to an appropriate agreement between the Company and a depository selected by it; provided, that such agreement shall provide that the holders of such depository receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of the Preferred Shares represented by such depository receipts. In lieu of fractional Preferred Shares that are not integral multiples of one one-thousandth (0.001) 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 a Preferred Share. For
purposes of this Section 14(b), the current market value of a Preferred Share shall be (x) one thousand multiplied by (y) the closing price of a Common Share (as determined pursuant to the second sentence of Section 1(j) hereof) for the Trading Day
immediately prior to the date of such exercise. 
  
 (c)    The Company shall not
be required to issue fractions of Common Shares or to distribute certificates that evidence fractional Common Shares upon the exercise or exchange of Rights. In lieu of such fractional Common Shares, the Company shall pay to the registered holders
of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of a Common Share. For purposes of this Section 14(c), the current market value of a Common
Share shall be the closing price of a Common Share (as determined pursuant to the second sentence of Section 1(j) 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 or her right to receive any fractional Rights or any
fractional shares (other than fractions that are integral multiples of one one-thousandth (0.001) of a Preferred Share) upon exercise of a Right. 
  
 Section 15.    Rights of Action.    All rights of action in respect of this Agreement, excepting the rights of action given to the Rights Agent hereunder,
are vested in the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common 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 his or her own behalf and for his or her own benefit, enforce, and
may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his or her right to exercise the Rights evidenced by such Rights Certificate in the manner provided in such Rights Certificate
and in this Agreement. Without limiting the foregoing or any remedies available to the holders of
 

 
 -26- 








 
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. 
  
 (a)    Notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a
result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, 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 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 are transferable only on the registry books of the Rights Agent if
surrendered at the office or offices of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates fully executed; and 
  
 (c)    subject to Sections 6(a) and 7(f) hereof, 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 Common Shares certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Rights Certificates or the associated Common Shares certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any
notice to the contrary. 
  
 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 to be 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 specifically 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. 

 
 -27- 








  
 Section 18.    Concerning the Rights Agent.

  
 (a)    The Company agrees to pay to the Rights Agent reasonable compensation
for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the preparation, delivery, amendment, administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or
expense (including, without limitation, the reasonable fees and expenses of legal counsel), incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent (each as 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. The costs
and expenses incurred in enforcing this right of indemnification and defending against any claim of liability shall be paid by the Company. The provisions of this Section 18 and Section 20 below shall survive the termination of this Agreement, the
exercise or expiration of the Rights and the resignation or removal of the Rights Agent. 
  
 (b)    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. 
  
 Section
19.    Merger or Consolidation or Change of Name of Rights Agent. 
  
 (a)    Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or
any successor Rights Agent shall be a party, or any Person succeeding to the shareholder services business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or
filing of any paper or any further act on the part of any of the parties hereto; provided, however, 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
 

 
 -28- 








 
countersign such Rights Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have the
full force provided in the Rights Certificates and in this Agreement. 
  
 (b)    In case at any time the name of the Rights Agent shall be changed and at such time any of the Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the
countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in
its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement. 
  
 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 and 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 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 Chief Financial Officer, the Secretary or any Assistant Secretary of the Company
and delivered to the Rights Agent; and such certificate shall be full and complete authorization and protection to the Rights Agent and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted by it under
the provisions of this Agreement in reliance upon such certificate. 
  
 (c)    The Rights Agent shall be liable hereunder to the Company and any other Person only for its own gross negligence, bad faith or willful misconduct (each as determined by a final, non-appealable order,
judgment, decree or ruling of a court of competent jurisdiction). Anything to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. Any liability of the Rights Agent under this Rights Agreement will be limited to the amount of fees paid by
the Company to the Rights Agent. 

 
 -29- 








  
 (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 liable nor responsible 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 liable or 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 liable or responsible for any change in the
exercisability of the Rights or any adjustment in the terms of the Rights (including the manner, method or amount thereof) provided for in Sections 3, 11, 13, 23 or 24, 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 by the Rights Agent of a certificate furnished pursuant to Section 12 describing such change or adjustment, upon which certificate 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 to be issued pursuant to this Agreement or any Rights Certificate or as to whether any
Preferred Shares 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 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 Chief Financial Officer, the Secretary or any Assistant Secretary of the Company, and to apply to such officers for advice or instructions in connection with its duties, and 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 Rights 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 (5) 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. 

 
 -30- 








  
 (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, omission, 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,
omission, default, neglect or misconduct, absent gross negligence or bad faith in the selection and continued employment thereof (which gross negligence or bad faith must be determined by a final, non-appealable order, judgment, decree or ruling of
a court of competent jurisdiction). 
  
 (j)    No provision of this Agreement
shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder 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 reasonably assured to it. 
  
 (k)    If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the form of assignment or form of election to purchase, as the case may be,
has either not been completed or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Company.

  
 Section 21.    Change of Rights Agent.    The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30) days’ notice in writing mailed to the Company and to each transfer agent of the Preferred Shares and the Common Shares by registered or
certified mail. The Company may remove the Rights Agent or any successor Rights Agent upon thirty (30) days’ notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the
Preferred Shares and the Common 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 thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the holder of a Rights Certificate (who shall, with such notice, submit his or her Rights Certificate for inspection by the Company), then the registered holder of any Rights Certificate may apply to
any court of competent jurisdiction for the appointment of a new Rights Agent. 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
 

 
 -31- 








 
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 Preferred Shares and the Common 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 its Board of Directors to reflect any adjustment or change in the Exercise Price and the number or kind or class of shares or other securities or property purchasable under the Rights Certificates
made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of Common Shares following the Distribution Date and prior to the redemption or expiration of the Rights, the Company (a) shall, with
respect to Common Shares so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement or upon the exercise, conversion or exchange of other securities of the Company outstanding at the date hereof or upon the
exercise, conversion or exchange of securities hereinafter issued by the Company and (b) may, in any other case, if deemed necessary or appropriate by the Board of Directors of the Company, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale; provided, however, that (i) no such Rights Certificate shall be issued and this sentence shall be null and void ab initio if, and to the extent that, such issuance or
this sentence would create a significant risk of or result in material adverse tax consequences to the Company or the Person to whom such Rights Certificate would be issued or would create a significant risk of or result in such options’ or
employee plans’ or arrangements’ failing to qualify for otherwise available special tax treatment and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu
of the issuance thereof. 
  
 Section 23.    Redemption. 
  
 (a)    The Company may, at its option and with the approval of the Company’s Board of Directors,
at any time prior to the Close of Business on the earlier of (i) the fifth day following the Shares Acquisition Date (or such later date as may be determined by action of the Company’s Board of Directors and publicly announced by the Company)
and (ii) the Final Expiration Date, redeem all but not less than all the then outstanding Rights at a redemption price of $0.001 per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the
date hereof (such redemption price being herein referred to as the “Redemption Price”) and the Company may, at its option, pay the Redemption Price either in Common Shares (based on the Current Per Share Market Price thereof
at the time of redemption) or cash. Such redemption of the Rights by the Company may be made effective at such time, on such basis and with such conditions as the Company’s Board of Directors in its sole discretion may establish. The date on
which the Company’s Board of Directors elects to make the redemption effective shall be referred to as the “Redemption Date.” 

 
 -32- 








  
 (b)    Immediately upon the action of the
Board of Directors of the Company ordering the redemption of the Rights, evidence of which shall have been filed with the Rights Agent, and without any further action and without any notice, the right to exercise the Rights will terminate and the
only right thereafter of the holders of Rights shall be to receive the Redemption Price. The Company shall promptly give public notice of any such redemption (with prompt notice thereof to the Rights Agent); provided, however, that the
failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Within ten (10) days after the action of the Company’s Board of Directors ordering the redemption of the Rights, the Company shall give notice
of such redemption to the Rights Agent and the holders of the then outstanding Rights by mailing such notice to all such holders at 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 that is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by
which the payment of the Redemption Price will be made. Neither the Company nor any of its Affiliates or Associates may redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this Section
23 or in Section 24 hereof, and other than in connection with the purchase of Common Shares prior to the Distribution Date. 
  
 Section 24.    Exchange. 
  
 (a)    Subject to applicable laws, rules and regulations, and subject to subsection 24(c) below, the Company may, at its option, by action of the Company’s Board of Directors, at any time after the occurrence
of a Triggering Event, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become null and void pursuant to the provisions of Section 7(e) hereof) for Common 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 (such exchange ratio being hereinafter referred to as the “Exchange Ratio”).
Notwithstanding the foregoing, the Company’s 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 Company’s Board of Directors
ordering the exchange of any Rights pursuant to Section 24(a) 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 such Rights held by such holder multiplied by the Exchange Ratio. The Company shall give public notice (with prompt notice thereof to the Rights Agent) of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company
 

 
 -33- 








 
shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice that is mailed in the
manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the Common Shares for Rights will be effected and, in the event of any partial
exchange, the number of Rights that will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become null and void pursuant to the provisions of Section 7(e) hereof) held by each
holder of Rights. 
  
 (c)    In the event that there shall not be sufficient
Common Shares issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with Section 24(a), the Company shall either take such action as may be necessary to authorize additional Common
Shares for issuance upon exchange of the Rights or alternatively, at the option of a majority of the Company’s Board of Directors, with respect to each Right (i) pay cash in an amount equal to the Current Value (as hereinafter defined), in lieu
of issuing Common Shares in exchange therefor, or (ii) issue debt or equity securities or a combination thereof, having a value equal to the Current Value, in lieu of issuing Common Shares in exchange for each such Right, where the value of such
securities shall be determined by a nationally recognized investment banking firm selected by majority vote of the Company’s Board of Directors, or (iii) deliver any combination of cash, property, Common Shares and/or other securities having a
value equal to the Current Value in exchange for each Right. For purposes of this Section 24(c) only, the Current Value shall mean the product of the Current Per Share Market Price of Common Shares on the date of the occurrence of the event
described above in subsection (a), multiplied by the number of Common Shares for which the Right otherwise would be exchangeable if there were sufficient shares available. To the extent that the Company determines that some action need be taken
pursuant to clauses (i), (ii) or (iii) of this Section 24(c), the Company’s Board of Directors may temporarily suspend the exercisability of the Rights for a period of up to sixty (60) days following the date on which the event described in
Section 24(a) shall have occurred, in order to seek any authorization of additional Common Shares and/or to decide the appropriate form of distribution to be made pursuant to the above provision and to determine the value thereof. In the event of
any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended. 
  
 (d)    The Company shall not be required to issue fractions of Common Shares or to distribute certificates that evidence fractional Common Shares. In lieu of such fractional Common
Shares, there shall be paid 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 (as determined pursuant to the second sentence of Section 1(j) hereof). 
  
 (e)    The Company may, at its option, by majority vote of the Company’s Board of Directors, at any time before any Person has become an Acquiring Person, exchange all or part of the then outstanding Rights
for rights of substantially equivalent value, as determined reasonably and with good faith by the Company’s Board of Directors based upon the advice of one or more nationally recognized investment banking firms. 

 
 -34- 








  
 (f)    Immediately upon the action of the
Company’s Board of Directors ordering the exchange of any Rights pursuant to Section 24(e) 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 rights in exchange therefor as has been determined by the Company’s Board of Directors in accordance with subsection 24(e) above. The Company shall give public notice (with prompt notice thereof to
the Rights Agent) of any such exchange; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company 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 transfer agent for the Common Shares of the Company. Any notice that is mailed in the manner herein provided shall be deemed given, whether or not the
holder receives the notice. Each such notice of exchange will state the method by which the exchange of the Rights will be effected. 
  
 Section 25.    Notice of Certain Events. 
  
 (a)    In case the Company shall propose to effect or permit to occur any Triggering Event or Section 13 Event, the Company shall give notice thereof to each holder of Rights in accordance with Section 26 hereof
at least twenty (20) days prior to occurrence of such Triggering Event or such Section 13 Event. 
  
 (b)    In case any Triggering Event or Section 13 Event shall occur, then, in any such case, the Company shall as soon as practicable thereafter give to each holder of a Rights Certificate and the Rights Agent, in
accordance with Section 26 hereof, a notice of the occurrence of such event, which shall specify the event and the consequences of the event to holders of Rights under Sections 11(a)(ii) and 13 hereof. 
  
 Section 26.    Notices.    Notices or demands authorized by this Agreement to be given or
made by the Rights Agent or by the holder of any Rights Certificate to or on the Company shall be sufficiently given or made if delivered, in the case of domestic delivery, by first-class mail, postage prepaid or by overnight courier service, or in

Section 27.    Supplements and Amendments.    Prior to the occurrence of a Distribution Date, the Company may supplement
or amend this Agreement in any respect without the approval of any holders of Rights and the Rights Agent shall, if the Company so instructs, execute such supplement or amendment. From and after the occurrence of a Distribution Date, the Company and
the Rights Agent may from time to time supplement or amend this Agreement without the approval of any holders of Rights in order to (i) cure any ambiguity, (ii) correct or supplement any provision contained herein which may be defective or
inconsistent with any other provisions herein, (iii) shorten or lengthen any time period hereunder or (iv) to change or supplement the provisions hereunder in any manner that the Company may deem necessary or desirable and that shall not adversely
affect the interests of the holders of Rights (other than an Acquiring Person or an Affiliate or Associate of an Acquiring Person); provided, this Agreement may not be supplemented or amended to lengthen, pursuant to clause (iii) of this
sentence, (A) a time period relating to when the
 

 
 -36- 








 
Rights may be redeemed at such time as the Rights are not then redeemable or (B) any other time period unless such lengthening is for the purpose of protecting, enhancing or clarifying the rights
of, and/or the benefits to, the holders of Rights (other than an Acquiring Person or an Affiliate or Associate of an Acquiring Person). Upon the delivery of a certificate from an appropriate officer of the Company that states that the proposed
supplement or amendment is in compliance with the terms of this Section 27 and provided that such supplement or amendment does not change or increase the Rights Agent’s rights, duties, liabilities or obligations hereunder, the Rights Agent
shall execute such supplement or amendment. Prior to the Distribution Date, the interests of the holders of Rights shall be deemed coincident with the interests of the holders of Common Shares. 
  

Section 28.    Successors.    All the covenants and provisions of this Agreement by or for the benefit of the Company or
the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder. 
  
 Section 29.    Determinations and Actions by the Company’s Board of Directors, etc.    For all purposes of this Agreement, any calculation of the number of Common Shares outstanding
at any particular time, including for purposes of determining the particular percentage of such outstanding Common Shares of which any Person is the Beneficial Owner, shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the
General Rules and Regulations under the Exchange Act. The Board of Directors of the Company shall have the exclusive power and authority to administer this Agreement and to exercise all rights and powers specifically granted to the Company’s
Board of Directors, or the Company, or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right and power (i) to interpret the provisions of this Agreement and (ii) to make all determinations
deemed necessary or advisable for the administration of this Agreement (including a determination to redeem or not redeem the Rights or to amend the Agreement). All such actions, calculations, interpretations and determinations (including, for
purposes of clause (y) below, all omissions with respect to the foregoing) which are done or made by the Company’s Board of Directors in good faith, shall (x) be final, conclusive and binding on the Company, the Rights Agent, the holders of the
Rights Certificates and all other parties and (y) with respect to claims specifically arising from the Agreement, not subject the Board of Directors of the Company to any liability to the holders of the Rights. The Rights Agent is entitled always to
assume the Company’s Board of Directors acted in good faith and shall be fully protected and incur no liability in reliance thereon. 
  
 Section 30.    Benefits of this Agreement.    Nothing in this Agreement shall be construed to give to any Person other than the Company, the Rights Agent and the registered
holders of the Rights Certificates (and, prior to the Distribution Date, the Common Shares) any legal or equitable right, remedy or claim pursuant to this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the
Rights Agent and the registered holders of the Rights Certificates (and, prior to the Distribution Date, the Common Shares). 
  
 Section 31.    Severability.    If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated; provided, however, that notwithstanding
anything in this Agreement to the contrary, if any such term, provision, covenant or restriction is held by such court or authority to be invalid, void or unenforceable and the Board of Directors of the Company determines in its good faith judgment
that severing the invalid language from this Agreement would adversely affect the purpose or effect of this Agreement, the right of redemption set forth in Section 23 hereof shall be reinstated and shall not expire until the Close of Business on the
tenth day following the date of such determination by the Company’s Board of Directors.

Law.    This Agreement and each Right and each Rights Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed in
accordance with the laws of such State applicable to contracts to be made and performed entirely within such State, except that all provisions regarding the rights, duties, obligations and immunities of the Rights Agent shall be governed by and
construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State.

 EXHIBIT A 
  
 FORM OF CERTIFICATE OF DESIGNATION OF RIGHTS, PREFERENCES AND 
 PRIVILEGES OF SERIES
A PARTICIPATING PREFERRED STOCK OF 
 CENTILLIUM COMMUNICATIONS, INC. 
  
 The undersigned, Darrel Slack, does hereby certify: 
  
 1.    That he is the duly elected and acting Chief Financial Officer of Centillium Communications, Inc., a Delaware corporation (the “Corporation”). 
  
 2.    That pursuant to the authority conferred upon the Corporation’s Board of Directors by the Amended and
Restated Certificate of Incorporation of the said Corporation, the said Board of Directors of the Corporation on December 27, 2002 adopted the following resolutions creating a series of Preferred Stock designated as Series A Participating Preferred
Stock: 
  
 “RESOLVED:    that pursuant to the authority vested in the Board of
Directors of the Corporation by the Amended and Restated Certificate of Incorporation, the Corporation’s Board of Directors does hereby provide for the issue of a series of Preferred Stock of the Corporation and does hereby fix and herein state
and express the designations, powers, preferences and relative and other special rights and the qualifications, limitations and restrictions of such series of Preferred Stock as follows: 
  
 Section 1.    Designation and Amount.    The shares of such series shall be designated as “Series A Participating
Preferred Stock.” The Series A Participating Preferred Stock shall have a par value of $0.001 per share, and the number of shares constituting such series shall be 500,000. 
  
 Section 2.    Proportional Adjustment.    In the event that the Corporation shall at any time after the issuance of any share
or shares of Series A Participating Preferred Stock (i) declare any dividend on Common Stock of the Corporation (“Common Stock”) payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine
the outstanding Common Stock into a smaller number of shares, then in each such case the Corporation shall simultaneously effect a proportional adjustment to the number of outstanding shares of Series A Participating Preferred Stock. 

 
 Section 3.    Dividends and Distributions. 
  

(a)    Subject to the prior and superior right of the holders of any shares of any series of Preferred Stock ranking prior and
superior to the shares of Series A Participating Preferred Stock with respect to dividends, the holders of shares of Series A Participating Preferred Stock shall be entitled to receive when, as and if declared by the Corporation’s Board of
Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the last day of March, June, September, and December in each year (each such date being referred to herein as a “Quarterly 

 







 
Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Participating Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to 1,000 times the aggregate per share amount of all cash dividends, and 1,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions
other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock since the immediately preceding Quarterly Dividend Payment Date, or,
with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Participating Preferred Stock. 
  
 (b)    The Corporation shall declare a dividend or distribution on the Series A Participating Preferred Stock as provided in paragraph
(a) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock). 
  
 (c)    Dividends shall begin to accrue on outstanding shares of Series A Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of
such shares of Series A Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of
issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Participating Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A
Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The
Corporation’s Board of Directors may fix a record date for the determination of holders of shares of Series A Participating Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be
no more than 30 days prior to the date fixed for the payment thereof. 
  
 Section 4.    Voting
Rights.    The holders of shares of Series A Participating Preferred Stock shall have the following voting rights:

Corporation. 
  
 (b)    Except as otherwise provided herein or by law, the
holders of shares of Series A Participating Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. 
  
 (c)    Except as required by law, the holders of Series A Participating Preferred Stock shall have no
special voting rights and their consent shall not be required (except to the extent that they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action.

 Section 5.    Certain Restrictions. 

 
 (a)    The Corporation shall not declare any dividend on, make any distribution on, or
redeem or purchase or otherwise acquire for consideration any shares of Common Stock after the first issuance of a share or fraction of a share of Series A Participating Preferred Stock unless concurrently therewith it shall declare a dividend on
the Series A Participating Preferred Stock as required by Section 3 hereof. 
  
 (b)    Whenever quarterly dividends or other dividends or distributions payable on the Series A Participating Preferred Stock as provided in Section 3 are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on shares of Series A Participating Preferred Stock outstanding shall have been paid in full, the Corporation shall not: 
  
 (i)    declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any
shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Participating Preferred Stock; 
  
 (ii)    declare or pay dividends on, or make any other distributions on any shares of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with the Series A Participating Preferred Stock, except dividends paid ratably on the Series A Participating Preferred Stock and all such parity stock on which dividends are payable or in arrears in
proportion to the total amounts to which the holders of all such shares are then entitled; 
  
 (iii)    redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Participating
Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution,
liquidation or winding up) to the Series A Participating Preferred Stock; or 
  
 (iv)    purchase or otherwise acquire for consideration any shares of Series A Participating Preferred Stock, or any shares of stock ranking on a parity with the Series A Participating Preferred Stock, except in
accordance with a purchase offer made in writing or by publication (as determined by the Corporation’s Board of Directors) to all holders of such shares upon such terms as the Corporation’s Board of Directors, after consideration of the
respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. 

 
 (c)    The Corporation shall not permit any subsidiary of the Corporation to purchase or
otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (a) of this Section 5, purchase or otherwise acquire such shares at such time and in such manner. 

 
 -3- 








  
 Section 6.    Reacquired
Shares.    Any shares of Series A Participating Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Corporation’s Board of Directors, subject to
the conditions and restrictions on issuance set forth herein and in the Amended and Restated Certificate of Incorporation, as then amended. 
  
 Section 7.    Liquidation, Dissolution or Winding Up.    Upon any liquidation, dissolution or winding up of the Corporation, the holders of shares of
Series A Participating Preferred Stock shall be entitled to receive an aggregate amount per share equal to 1,000 times the aggregate amount to be distributed per share to holders of shares of Common Stock plus an amount equal to any accrued and
unpaid dividends on such shares of Series A Participating Preferred Stock. 
  
 Section
8.    Consolidation, Merger, etc.    In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed
into other stock or securities, cash and/or any other property, then in any such case the shares of Series A Participating Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share equal to 1,000 times the
aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. 
  
 Section 9.    No Redemption.    The shares of Series A Participating Preferred Stock shall not be redeemable. 

 
 Section 10.    Ranking.    The Series A Participating Preferred Stock shall rank
junior to all other series of the Corporation’s Preferred Stock as to the payment of dividends and the distribution of assets, unless the terms of any such series shall provide otherwise. 
  

Section 11.    Amendment.    The Amended and Restated Certificate of Incorporation of the Corporation shall not be
further amended in any manner which would materially alter or change the powers, preference or special rights of the Series A Participating Preferred Stock so as to affect them adversely without the affirmative vote of the holders of a majority of
the outstanding shares of Series A Participating Preferred Stock, voting separately as a series. 
  
 Section
12.    Fractional Shares.    Series A Participating Preferred Stock may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to
exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Participating Preferred Stock.

 EXHIBIT C 
  
 STOCKHOLDER RIGHTS PLAN 
 CENTILLIUM COMMUNICATIONS, INC. 

 
 Summary of Rights 
  
 
	 
	 Distribution and Transfer of Rights; Rights Certificate:
 	  	 The Board of Directors of the Company has declared a dividend of one Right for each share of Common Stock of Centillium Communications, Inc. (the
“Company”) outstanding. Prior to the Distribution Date referred to below, the Rights will be evidenced by and trade with the certificates for the Common Stock. After the Distribution Date, the Company will mail Rights
certificates to the Company’s stockholders and the Rights will become transferable apart from the Common Stock.
 
	 
	 Distribution Date:
 	  	 Rights will separate from the Common Stock and become exercisable following (a) the tenth day (or such later date as may be determined by the Company’s
Board of Directors) after a person or group acquires beneficial ownership of 15% or more of the Company’s Common Stock or (b) the tenth business day (or such later date as may be determined by the Company’s Board of Directors) after a
person or group announces a tender or exchange offer, the consummation of which would result in ownership by a person or group of 15% or more of the Company’s Common Stock.
 
	 
	 Preferred Stock Purchasable Upon Exercise of Rights:
 	  	 After the Distribution Date, each Right will entitle the holder to purchase for $25.00 (the “Exercise Price”), a fraction of a share of
the Company’s Preferred Stock with economic terms similar to that of one share of the Company’s Common Stock.
 
	 
	 Flip-In:
 	  	 If an acquirer (an “Acquiring Person”) obtains 15% or more of the Company’s Common Stock, then each Right (other than Rights owned
by an Acquiring Person or its affiliates) will entitle the holder thereof to purchase, for the Exercise Price, a number of shares of the Company’s Common Stock having a then-current market value of twice the Exercise Price.
 
	 
	 Flip-Over:
 	  	 If, after an Acquiring Person obtains 15% or more of the Company’s Common Stock, (a) the Company merges into another entity, (b) an acquiring entity merges
into the Company or (c) the Company sells more than 50% of the Company’s assets or earning power, then each Right (other than Rights owned by an Acquiring Person or its affiliates) will entitle the holder thereof to purchase, for the Exercise
Price, a number of shares of Common Stock of the person engaging in the transaction having a then current market value of twice the Exercise Price.
 

 







  
 
	 Exchange Provision:
 	  	 At any time after the date on which an Acquiring Person obtains 15% or more of the Company’s Common Stock and prior to the acquisition by the Acquiring
Person of 50% of the outstanding Common Stock, the Board of Directors of the Company may exchange the Rights (other than Rights owned by the Acquiring Person or its affiliates), in whole or in part, for shares of Common Stock of the Company at an
exchange ratio of one share of Common Stock per Right (subject to adjustment).
 
	 
	 Redemption of the Rights:
 	  	 Rights will be redeemable at the Company’s option for $0.001 per Right at any time on or prior to the fifth day (or such later date as may be determined by
the Company’s Board of Directors) after public announcement that a Person has acquired beneficial ownership of 15% or more of the Company’s Common Stock (the “Shares Acquisition Date”).
 
	 
	 Expiration of the Rights:
 	  	 The Rights expire on the earliest of (a) January 9, 2013 or (b) exchange or redemption of the Rights as described above.
 
	 
	 Amendment of Terms of Rights:
 	  	 The terms of the Rights and the Rights Agreement may be amended in any respect without the consent of the Rights holders on or prior to the Distribution Date;
thereafter, the terms of the Rights and the Rights Agreement may be amended without the consent of the Rights holders in order to cure any ambiguities or to make changes which do not adversely affect the interests of Rights holders (other than the
Acquiring Person).
 
	 
	 Voting Rights:
 	  	 Rights will not have any voting rights.
 
	 
	 Anti-Dilution Provisions:
 	  	 Rights will have the benefit of certain customary anti-dilution provisions.
 
	 
	 Taxes:
 	  	 The Rights distribution should not be taxable for federal income tax purposes. However, following an event that renders the Rights exercisable or upon
