This Tax Benefit Protection Plan Agreement, dated as of January 28, 2013, is by and between Integrated Electrical Services, Inc., a
Delaware corporation (the “Company”), and American Stock Transfer & Trust Company, LLC, a New York limited liability trust company (the “Rights Agent”). 

RECITALS: 

WHEREAS, the Company and its subsidiaries have generated NOLs (as defined in Section 1 hereof) for United States federal
income tax purposes; and such NOLs may potentially provide valuable Tax Benefits (as defined in Section 1 hereof) to the Company, and the Company desires to avoid an “ownership change” within the meaning of Section 382 of
the Internal Revenue Code of 1986, as amended (the “Code”) and the Treasury Regulations (as defined in Section 1 hereof) promulgated thereunder, and thereby preserve its unrestricted use of such NOLs and certain other
Tax Benefits; and 
 WHEREAS, in furtherance of such objective, the Company desires to enter into this Agreement; and

 WHEREAS, the Board of Directors of the Company on January 24, 2013 (the “Rights Dividend Declaration
Date”) (i) authorized the issuance and declared a dividend of one preferred share purchase right (a “Right”) for each share of the common stock, par value $0.01 per share, of the Company (the “Common
Stock”) outstanding as of the close of business on February 19, 2013 (the “Record Date”), each Right representing the right to purchase one one-thousandth of a share of Series A Junior Participating Preferred Stock of
the Company having the rights, powers and preferences set forth in the form of Certificate of Designation attached hereto as Exhibit A upon the terms and subject to the conditions hereinafter set forth, and (ii) further authorized the issuance
of one Right with respect to each share of Common Stock that shall become outstanding between the Record Date and the earliest to occur of the Distribution Date, the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined);

holders of Common Stock) in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such co-Rights Agents as it may deem necessary or desirable. 

Section 3. Issue of Right Certificates. (a) Until the earlier of (i) the close of business on the tenth day after
the Stock Acquisition Date (or, if the tenth day after the Stock Acquisition Date occurs before the Record Date, then the Record Date) and (ii) the close of business on the tenth Business Day (or such later date as may be determined by action
of the Board of Directors prior to such time as any Person becomes an Acquiring Person) after the date of the commencement by any Person (other than an Exempt Person) of, or of the first public announcement of the intention of such Person (other
than an Exempt Person) to commence, a tender or exchange offer the consummation of which would result in any Person (other than an Exempt Person) becoming an Acquiring Person (including any such date which is after the date of this Agreement and
prior to the issuance of the Rights), the earlier of such dates being herein referred to as the “Distribution Date”), (x) the Rights will be evidenced (subject to the provisions of Section 3(b) hereof) by the
certificates for Common Stock registered in the names of the holders thereof (or by Book Entry in respect of shares of Common Stock) and not by separate Right Certificates, and (y) the Rights will be transferable only in connection with the
transfer of Common Stock. As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign, and the Company will send or cause to be sent (and the Rights Agent will, if requested, send) by
first-class, insured, postage-prepaid mail, to each record holder of Common Stock as of the close of business on the Distribution Date (other than any Acquiring Person or any Associate or Affiliate of an Acquiring Person), at the address of such
holder shown on the records of the Company, a Right Certificate, in substantially the form of Exhibit B hereto (a “Right Certificate”), evidencing one Right (subject to adjustment as provided herein) for each share of Common Stock
so held. As of the Distribution Date, the Rights will be evidenced solely by such Right Certificates. 

  
 8 

 (b) Attached hereto as Exhibit C is a Summary of Rights to Purchase Shares of
Preferred Stock (the “Summary of Rights”). As promptly as practicable following the Record Date, the Company shall send a copy of the Summary of Rights in substantially the form attached as Exhibit C to each record holder of
Common Stock as of the close of business on the Record date at the address shown on the records of the Company. With respect to certificates for Common Stock outstanding as of the date hereof, 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. Until the Distribution Date (or the earlier of the Redemption Date or the Final Expiration Date), the surrender for transfer of any
certificate for Common Stock outstanding as of the date hereof, with or without a copy of the Summary of Rights, shall also constitute the transfer of the Rights associated with the Common Stock represented thereby. 

(c) Rights shall be issued in respect of all shares of Common Stock which are issued (whether originally issued or from the
Company’s treasury) after the Record Date but before the earliest of the Distribution Date, the Final Expiration Date and the Redemption Date. Certificates issued for Common Stock (including, without limitation, upon transfer of outstanding
Common Stock, disposition of Common Stock out of treasury stock or issuance or reissuance of Common Stock out of authorized but unissued shares) after the date hereof but prior to the earliest of the Distribution Date, the Redemption Date and the
Final Expiration Date shall also be deemed to be certificates for the Rights, and shall have impressed on, printed on, written on or otherwise affixed to them the following legend: 

This certificate also evidences and entitles the holder hereof to certain rights, subject to adjustment, as set forth in a Tax Benefit
Protection Plan Agreement between Integrated Electrical Services, Inc. and American Stock Transfer & Trust Company, LLC, dated as of January 28, 2013 as the same may be amended from time to time (the “Rights
Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of Integrated Electrical Services, 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. Integrated Electrical Services, Inc. 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, as set forth in the Rights Agreement, Rights owned by or transferred to any Person who becomes an Acquiring Person (as defined in the Rights Agreement) and certain transferees
thereof will become null and void and will no longer be transferable. 
 With respect to Book Entry shares of Common Stock, such legend shall be
included in a notice to the registered holder of such shares in accordance with applicable law. With respect to such certificates containing the foregoing legend, or any notice of the foregoing legend delivered to the holders of Book Entry shares,
until the earlier of the Distribution Date and the Final Expiration Date, the Rights associated with the Common Stock represented by such certificates or Book Entry shares shall be evidenced by such certificates or Book Entry shares alone, and the
surrender for transfer of any such certificate, except as otherwise provided herein, shall also constitute the transfer of the Rights associated with the Common Stock represented thereby. In the event that the Company purchases or otherwise acquires
any Common Stock after the date hereof but prior to the Distribution Date, any Rights associated with such Common Stock shall be deemed cancelled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common
Stock which are no longer outstanding. 

  
 9 

 Notwithstanding this Section 3(c), neither the omission of a legend nor the
failure to deliver the notice of the legend required hereby shall affect the enforceability of any part of this Agreement or the rights of any holder of the Rights. 
 Section 4. Form of Right Certificates. (a) The Right Certificates (and the forms of election to purchase shares and of assignment to be printed on the reverse thereof) shall be
substantially in the form set forth in Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are not inconsistent with the
provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of the NASDAQ or of any other stock exchange or automated quotation system on
which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Sections 11 and 22 hereof, the Right Certificates shall entitle the holders thereof to purchase such number of one one-thousandths
of a share of Preferred Stock as shall be set forth therein at the price per one one-thousandth of a share of Preferred Stock set forth therein (as determined pursuant to Section 7; the “Purchase Price”), but the number
of such one one-thousandths of a share of Preferred Stock and the Purchase Price shall be subject to adjustment as provided herein. 
 (b) Any Right Certificate issued pursuant to Section 3(a), Section 11(i) or Section 22 hereof that represents Rights Beneficially Owned by any Person known to be:
(i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such, (iii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for
consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom such Acquiring Person has any continuing plan, agreement, arrangement or understanding regarding the transferred Rights or
(B) a transfer which the Board of the Company has determined is part of a plan, agreement, arrangement or understanding which has as a primary purpose or effect avoidance of Section 7(e) hereof, or (iv) subsequent transferees
of such Persons described in clause (i), (ii) or (iii) of this sentence, and any Right Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer, exchange, replacement or adjustment of any other
Right Certificate referred to in this sentence, shall contain (to the extent feasible) a legend substantially in the following form: “The Rights represented by this Right Certificate are or were Beneficially Owned by a Person who was or became
an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Rights Agreement). Accordingly, this Right Certificate and the Rights represented hereby may become null and void in the circumstances
specified in Section 7(e) of such Agreement.” The absence of the foregoing legend on any Right Certificate shall in no way affect any of the other provisions of this Agreement, including, without limitation, the provisions of
Section 7(e). 

  
 10 

 Section 5. Countersignature and Registration. (a) The Right Certificates
shall be executed on behalf of the Company by the President or any of the Vice Presidents, the Treasurer or the Controller of the Company, either manually or by facsimile signature, shall have affixed thereto the Company’s seal or a facsimile
thereof (if the Company has a seal), and shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile signature. The Right 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 Right Certificates shall cease to be such officer of the Company before countersignature by the Rights Agent and issuance and delivery
by the Company, such Right 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 Right Certificates had not ceased to be such
officer of the Company; and any Right Certificate may be signed on behalf of the Company by any Person who, at the actual date of the execution of such Right Certificate, shall be a proper officer of the Company to sign such Right Certificate,
although at the date of the execution of this Agreement any such Person was not such an officer. 
 (b) Following the
Distribution Date, the Rights Agent will keep or cause to be kept, at an office or agency designated as the appropriate place for surrender of Right Certificates upon exercise or transfer, books for registration and transfer of the Right
Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Right Certificates, the number of Rights evidenced on its face by each of the Right Certificates and the date of each of the Right
Certificates. 
 Section 6. Transfer, Split Up, Combination and Exchange of Right Certificates; Mutilated, Destroyed,
Lost or Stolen Right Certificates. (a) Subject to the provisions of Sections 7(e), 11(a)(ii) and 14 hereof, at any time after the close of business on the Distribution Date, and prior to the close of business on the
earlier of the Redemption Date and the Final Expiration Date, any Right Certificate or Right Certificates may be transferred, split up, combined or exchanged for another Right Certificate or Right Certificates, entitling the registered holder to
purchase a like number of one one-thousandths of a share of Preferred Stock (or, following a Section 11(a)(ii) Event, Common Stock, other securities, cash or other assets, as the case may be) as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase. Any registered holder desiring to transfer, split up, combine or exchange any Right Certificate or Right Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be transferred, split up, combined or exchanged at the office or agency 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 Right Certificate until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Right
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
countersign and deliver to the Person entitled thereto a Right Certificate or Right Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Right Certificates. The Rights Agent shall promptly forward any such sum collected by it to the Company or to such Person(s) as the Company shall specify by written notice.

  
 11 

 (b) Subject to the provisions of Section 11(a)(ii) hereof, at any time after the
Distribution Date and prior to the close of business on the earlier of the Redemption Date and the Final Expiration Date, upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or
mutilation of a Right Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably 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 Right Certificate if mutilated, the Company will make and deliver a new Right Certificate of like tenor to the Rights Agent for delivery to the registered holder in
lieu of the Right Certificate so lost, stolen, destroyed or mutilated. 
 Section 7. Exercise of Rights, Purchase Price;
Final Expiration Date of Rights. (a) Subject to Section 7(e) and Section 27 hereof, the registered holder of any Right Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein, including, without
limitation, the restrictions on exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23 hereof) in whole or in part at any time after the Distribution Date upon surrender of the Right
Certificate, with the form of election to purchase and the certificate on the reverse side thereof duly executed, to the Rights Agent at the principal office or offices of the Rights Agent designated for such purpose, together with payment of the
aggregate Purchase Price with respect to the total number of one one-thousandth of a share of Preferred Stock (or other securities, cash or other assets, as the case may be) as to which such surrendered Rights are then exercisable, at or prior to
the earliest of (i) the close of business on the Final Expiration Date, (ii) the Redemption Date, and (iii) the time at which all of the Rights (other than Rights that have become void pursuant to the provisions of
Section 7(e) hereof) are exchanged for Common Stock or other assets or securities as provided in Section 27 hereof (the earliest of (i) and (ii) and (iii) being herein referred to as the “Expiration
Date”). 
 (b) The Purchase Price shall be initially $20.00 (the “Purchase Price”) for each
one-thousandth of a share of Preferred Stock purchasable upon the exercise of a Right. The Purchase Price and the number of one one-thousandths of a share of Preferred Stock or other securities or property to be acquired upon exercise of a Right
shall be subject to adjustment from time to time as provided in Section 11 hereof and shall be payable in lawful money of the United States of America in accordance with Section 7(c). 

(c) Except as otherwise provided herein, upon receipt of a Right Certificate representing exercisable Rights, with the form of election
to purchase duly executed, accompanied by payment of the aggregate Purchase Price for the shares of Preferred Stock to be purchased and an amount equal to any applicable transfer tax required to be paid by the holder of such Right Certificate in
accordance with Section 9 hereof, in cash or by certified check, cashier’s check or money order payable to the order of the Company, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly
(i) (A) requisition from any transfer agent of the Preferred Stock certificates for the number of shares of Preferred Stock to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests,
or (B) requisition from the depositary agent depositary receipts representing interests in such number of one one-thousandths of a share of Preferred Stock as are to be purchased (in which case certificates for the Preferred Stock represented
by such receipts shall be deposited by the transfer agent with the depositary agent) and the Company hereby directs the depositary agent to 

  
 12 

 
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) promptly after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or names as may be designated by
such holder and (iv) when appropriate, after receipt, promptly deliver such cash to or upon the order of the registered holder of such Right Certificate. If the Company is obligated to issue other securities (including Common Stock) of the
Company, pay cash and/or distribute other property pursuant to Section 11(a) hereof, the Company will make all arrangements necessary so that such other securities, cash and/or other property are available for distribution by the Rights
Agent, if and when appropriate. The Company reserves the right to require prior to the occurrence of a Section 11(a)(ii) Event that, upon any exercise of Rights, a number of Rights be exercised so that only whole shares of Preferred
Stock would be issued. 
 (d) Except as otherwise provided herein, in case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent to the exercisable Rights remaining unexercised shall be issued by the Rights Agent to the registered holder of such Right Certificate or to
his duly authorized assigns, subject to the provisions of Section 14 hereof. 
 (e) Notwithstanding anything in this
Agreement to the contrary, from and after the first occurrence of a Section 11(a)(ii) Event, any Rights Beneficially Owned by any Person known to be (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, (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 plan, agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors has determined is part of a plan,
agreement, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e), or (iv) subsequent transferees of such Persons described in clause (i), (ii) or (iii) of this sentence,
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 use all reasonable efforts
to insure that the provisions of this Section 7(e) and Section 4(b) hereof are complied with, but shall have no liability to any holder of Right Certificates or other Person as a result of its failure to make any
determinations with respect to an Acquiring Person or any of its 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 of Rights upon the occurrence of any purported transfer or exercise
of Rights pursuant to Section 6 hereof or this Section 7 unless such registered holder shall have (i) properly completed and signed the certificate contained in the form of assignment or election to purchase set forth on
the reverse side of the Right Certificate surrendered for such transfer or exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) thereof as the Company shall reasonably request.

  
 13 

 Section 8. Cancellation and Destruction of Right Certificates. All Right
Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Rights Agent for cancellation or in cancelled form, or, if
surrendered to the Rights Agent, shall be cancelled by it, and no Right Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for
cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Right Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Right Certificates
to the Company, or shall, at the written request of the Company, destroy such cancelled Right Certificates, and in such case shall deliver a certificate of destruction thereof to the Company. 

Section 9. Reservation and Availability of Shares of Preferred Stock. 

(a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of
Preferred Stock or any shares of Preferred Stock held in its treasury (and, following the occurrence of a Section 11(a)(ii) Event, out of its authorized and unissued shares of Common Stock and/or other securities or out of its authorized
and unissued shares held in its treasury), the number of shares of Preferred Stock (and, following the occurrence of a Section 11(a)(ii) Event, Common Stock or other securities) that will be sufficient to permit the exercise in full of
all outstanding Rights in accordance with this Agreement. 
 (b) So long as the shares of Preferred Stock (and, following the
time that a Section 11(a)(ii) Event, shares of Common Stock and other securities) issuable and deliverable upon the exercise of Rights may be listed or admitted to trading on the NASDAQ or listed on any other national securities exchange
or quotation system, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance to be listed or admitted to trading on the NASDAQ or listed on any other exchange
or quotation system upon official notice of issuance upon such exercise. 
 (c) From and after such time as the Rights become
exercisable, the Company shall use its best efforts, if then necessary to permit the issuance of shares of Preferred Stock (and following the time that a Person first becomes an Acquiring Person, shares of Common Stock and other securities) upon the
exercise of Rights, to register and qualify such shares of Preferred Stock (and following the time that a Person first becomes an Acquiring Person, shares of Common Stock and other securities) under the Securities Act and any applicable state
securities or “Blue Sky” laws (to the extent exemptions therefrom are not available), cause such registration statement and qualifications to become effective as soon as possible after such filing and keep such registration and
qualifications effective until the earlier of the date as of which the Rights are no longer exercisable for such securities and the Final Expiration Date. The Company may temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file a registration statement under the Securities Act and permit it to become effective. Upon any such suspension, the Company shall issue a public

  
 14 

 
announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. Notwithstanding
any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction unless the requisite qualification in such jurisdiction shall have been obtained and until a registration statement under the Securities Act (if
required) shall have been declared effective. 
 (d) The Company covenants and agrees that it will take all such action as may be
necessary to ensure that all shares of Preferred Stock (and, following the time that a Person becomes an Acquiring Person, shares of Common Stock and other securities) delivered upon exercise of Rights shall, at the time of delivery of the
certificates therefor (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable shares. 
 (e) The Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges which may be payable in respect of the issuance or delivery of
the Right Certificates or of any shares of Preferred Stock (or shares of Common Stock or other securities) upon the exercise of Rights. The Company shall not, however, be required to pay any transfer tax which may be payable in respect of any
transfer or delivery of Right Certificates to a Person other than, or the issuance or delivery of certificates or depositary receipts for the Preferred Stock (or shares of Common Stock or other securities) in a name other than that of, the
registered holder of the Right Certificate evidencing Rights surrendered for exercise or to issue or deliver any certificates or depositary receipts for Preferred Stock (or shares of Common Stock or other securities) upon the exercise of any Rights
until any such tax shall have been paid (any such tax being payable by that holder of such Right Certificate at the time of surrender) or until it has been established to the Company’s reasonable satisfaction that no such tax is due.

 Section 10. Preferred Stock Record Date. Each Person in whose name any certificate for Preferred Stock is issued
upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the shares of Preferred Stock represented thereby on, and such certificate shall be dated, the date upon which the Right Certificate evidencing such
Rights was duly surrendered and payment of the Purchase Price (and any applicable transfer taxes) was made; provided, however, that if the date of such surrender and payment is a date upon which the Preferred Stock (or Common Stock or
other securities, as the case may be) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares (fractional or otherwise) on, and such certificate shall be dated, the next succeeding
Business Day on which the Preferred Stock (or Common Stock or other securities, as the case may be) transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Right Certificate shall not be
entitled to any rights of a holder of Preferred Stock for which the Rights shall be exercisable, including, without limitation, the right to vote or to receive dividends or other distributions, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein. 

  
 15 

 Section 11. Adjustment of Purchase Price, Number of Shares and Number of Rights.
The Purchase Price, the number of shares of Preferred Stock or other securities or property purchasable upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this
Section 11. 
 (a) (i) If the Company shall at any time after the date of this Agreement
(A) declare a dividend on the Preferred Stock payable in shares of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller number of Preferred Stock or (D) issue
any shares of its capital stock in a reclassification of the Preferred Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise
provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the
number and kind of shares of capital stock issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive the aggregate number and kind of shares of capital stock
which, if such Right had been exercised immediately prior to such date and at a time when the Preferred Stock transfer books of the Company were open, the holder would have owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination or reclassification; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the
Company issuable upon exercise of one Right. If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i)
shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii) hereof. 
 (ii) Subject to the provisions of this Agreement, including, without limitation, Section 27 hereof, if any Person becomes an Acquiring Person, then, promptly following the occurrence of such
event, proper provision shall be made so that each holder of a Right (except as provided below and in Section 7(e) hereof) shall thereafter have the right to receive, upon exercise thereof at the then current Purchase Price in accordance
with the terms of this Agreement, in lieu of a number of one one-thousandths of a share of Preferred Stock, such number of shares of Common Stock of the Company as shall equal the result obtained by (x) multiplying the then current Purchase
Price by the then number of one one-thousandths of a share of Preferred Stock for which a Right was exercisable immediately prior to the first occurrence of a Section 11(a)(ii) Event, and (y) dividing that product (which, following
such first occurrence, shall thereafter be referred to as the “Purchase Price” for each Right and for all purposes of this Agreement) by 50% of the Current Market Price (determined pursuant to Section 11(d) hereof) per
share of Common Stock on the date of such first occurrence (such number of shares, the “Adjustment Shares”). 
 (iii) If the number of shares of Common Stock which are authorized by the Company’s Certificate of Incorporation but not outstanding, subscribed for or reserved for issuance for purposes other than
upon exercise of the Rights are not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a), the Company shall (A) determine the value of the Adjustment
Shares issuable upon the exercise of a Right (the “Current Value”), and 

  
 16 

 
(B) with respect to each Right (subject to Section 7(e) hereof), make adequate provision to substitute for the Adjustment Shares, upon the exercise of a Right and payment of the
applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) other equity securities of the Company (including, without limitation, shares, or units of shares, of preferred stock, such as the Preferred Stock, which
the Board of Directors has deemed to have essentially the same value or economic rights as shares of Common Stock), (4) debt securities of the Company, (5) other assets, or (6) any combination of the foregoing, having an aggregate
value equal to the Current Value (less the amount of any reduction in the Purchase Price), where such aggregate value has been determined by the Board based upon the advice of a nationally recognized investment banking firm selected by the Board;
provided, however, that if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within 30 days following the later of (x) the first occurrence of a Section 11(a)(ii)
Event and (y) the date on which the Company’s right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the “Section 11(a)(ii) Trigger Date”), then
the Company shall be obligated to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, shares of Common Stock (to the extent available), and then, if necessary, cash, which shares and/or cash have
an aggregate value equal to the Spread. For purposes of the preceding sentence, the term “Spread” shall mean the excess of (i) the Current Value over (ii) the Purchase Price. If the Board of Directors determines in good
faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, the 30-day period set forth above may be extended to the extent necessary, but not more than 90 days
after the Section 11(a)(ii) Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares (such 30-day period, as it may be extended, is herein called the “Substitution
Period”). To the extent that the Company determines that action should be taken pursuant to the first and/or third sentences of this Section 11(a)(iii), the Company (1) shall provide, subject to Section 7(e)
hereof, that such action shall apply uniformly to all outstanding Rights, and (2) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek such stockholder approval for such authorization of
additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that
the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of each Adjustment Share shall be
the Current Market Price per share of the Common Stock on the Section 11(a)(ii) Trigger Date and the per share or per unit value of any Common Stock Equivalent shall be deemed to equal the Current Market Price per share of the Common
Stock on such date. 
 (b) In case the Company shall fix a record date for the issuance of rights, options or
warrants to all holders of Preferred Stock entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Preferred Stock (or shares having similar rights, privileges and preferences as the
Preferred Stock (“Equivalent Preferred Stock”)) or securities convertible into Preferred Stock or Equivalent Preferred Stock at a price per share of Preferred Stock or Equivalent Preferred

  
 17 

 
Stock (or having a conversion price per share, if a security convertible into shares of Preferred Stock or Equivalent Preferred Stock) less than the then current per share market price of the
Preferred Stock (determined pursuant to Section 11(d) hereof) on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record
date by a fraction, the numerator of which shall be the number of shares of Preferred Stock and Equivalent Preferred Stock outstanding on such record date plus the number of shares of Preferred Stock and Equivalent Preferred Stock which the
aggregate offering price of the total number of shares of Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such
current market price, and the denominator of which shall be the number of shares of Preferred Stock and Equivalent Preferred Stock outstanding on such record date plus the number of additional shares of Preferred Stock and/or Equivalent Preferred
Stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible); provided, however, that in no event shall the consideration to be paid upon the exercise of one
Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon exercise of one Right. In case such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent. Shares of Preferred Stock and Equivalent Preferred Stock owned by or held
for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed; and if such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. 
 (c) In case the Company shall fix a record date for the making of a distribution to all holders of the Preferred Stock (including any such distribution made in connection with a consolidation or merger in
which the Company is the continuing or surviving corporation) of evidences of indebtedness or assets (other than a regular quarterly cash dividend or a dividend payable in Preferred Stock) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be
the then Current Market Price per share of the Preferred Stock (determined pursuant to Section 11(d) hereof) on such record date, less the fair market value (as determined in good faith by the Board of Directors whose determination shall
be described in a statement filed with the Rights Agent) of the portion of the assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to one share of Preferred Stock, and the denominator of
which shall be such current per share market price (determined pursuant to Section 11(d) hereof) of the Preferred Stock; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right
be less than the aggregate par value of the shares of capital stock of the Company to be issued upon exercise of one Right. Such adjustments shall be made successively whenever such a record date is fixed; and if such distribution is not so made,
the Purchase Price shall again be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. 

  
 18 

 (d) (i) Except as otherwise provided herein, for the purpose of any
computation hereunder (other than computations made pursuant to Section 11(a)(ii) hereof), the Current Market Price per share of any security (a “Security” for the purpose of this Section 11(d)(i)) on any
date shall be deemed to be the average of the daily closing prices per share of such Security for the 30 consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date, and for purposes of computations made pursuant to
Section 11(a)(iii) hereof, the Current Market Price per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such Common Stock for the ten (10) consecutive Trading Days
immediately following such date; provided, however, that in the event that the Current Market Price per share of the Common Stock is determined during a period following the announcement by the issuer of such Common Stock of (A) a
dividend or distribution on such Common Stock payable in shares of such Common Stock or securities convertible into shares of such Common Stock (other than the Rights), or (B) any subdivision, combination or reclassification of such Common
Stock, and the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification shall not have occurred prior to the commencement of the requisite 30 Trading Day or ten (10) Trading
Day period, as set forth above, then, and in each such case, the Current Market Price shall be properly adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sale price, regular way, or, in case no such
sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New
York Stock Exchange or NASDAQ or, if the shares Common Stock is not listed or admitted to trading on the New York Stock Exchange or NASDAQ, as reported in the principal consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the shares of Common Stock is listed or admitted to trading or, if the shares of Common Stock is not listed or admitted to trading on any national securities exchange, the last quoted price or, if
not so quoted, the average of the high bid and low asked prices in the over-the-counter market or such other system then in use, or, if on any such date the shares of Common Stock is not so quoted, the average of the closing bid and asked prices as
furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors. If on any such date no market maker is making a market in the Common Stock, the fair value of such shares on such date as determined in
good faith by the Board shall be used. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the shares of Common Stock is listed or admitted to trading is open for the transaction of
business or, if the shares of Common Stock is not listed or admitted to trading on any national securities exchange, a Business Day. If the Common Stock is not publicly held or not so listed or traded, Current Market Price per share shall mean the
fair value per share as determined in good faith by the Board, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. 

  
 19 

 (ii) For the purpose of any computation hereunder, the Current Market Price
per share of Preferred Stock shall be determined in the same manner as set forth above for the Common Stock in clause (i) of this Section 11(d) (other than the last sentence thereof). If the Current Market Price per share of
Preferred Stock cannot be determined in the manner provided above or if the Preferred Stock is not publicly held or listed or traded in a manner described in clause (i) of this Section 11(d), the Current Market Price per share of
Preferred Stock shall be conclusively deemed to be an amount equal to 1,000 (as such number may be appropriately adjusted for such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock occurring after the
date of this Agreement) multiplied by the Current Market Price per share of the Common Stock. If neither the Class A Common Stock nor the Preferred Stock is publicly held or so listed or traded, Current Market Price per share of the Preferred
Stock shall mean the fair value per share as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. 

(e) No adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of
at least 1% in the Purchase Price; provided, however, that any adjustments which by reason of this Section 11(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All
calculations under this Section 11 shall be made to the nearest cent or to the nearest one ten-thousandth of a share of Preferred Stock or share of Common Stock or other share or security as the case may be. Notwithstanding the first
sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction which requires such adjustment and(ii) the date of
the expiration of the right to exercise any Rights. 
 (f) If as a result of an adjustment made pursuant to
Section 11(a)(ii) hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than the Preferred Stock, thereafter the Purchase Price and the number of such other
shares so receivable upon exercise of a Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in
Sections 11(a), 11(b), 11(c), 11(e), 11(g), 11(h), 11(i), 11(j), 11(k) and 11(m) and the provisions of Sections 7, 9, 10 and 14 hereof with
respect to the Preferred Stock shall apply on like terms to any such other shares. 
 (g) All Rights originally
issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-thousandths of a share of Preferred Stock purchasable from time to
time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein. 
 (h) Unless
the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and (c), each Right outstanding immediately prior
to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted 

  
 20 

 
Purchase Price, that number of one one-thousandths of a share of Preferred Stock (calculated to the nearest one ten-thousandth of a share of Preferred Stock) obtained by (i) multiplying
(x) the number of one one-thousandths of a share covered by a Right immediately prior to such adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so
obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price. 
 (i) The
Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in substitution for any adjustment in the number of one one-thousandths of a share of Preferred Stock 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 one-thousandths of a share of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each
Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase
Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at
the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been issued, shall be at least 10 days later than the date of the
public announcement. If Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company may, as promptly as practicable, cause to be distributed to holders of record of Right
Certificates on such record date Right 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 Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Right Certificates evidencing all
the Rights to which such holders shall be entitled after such adjustment. Right Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein and shall be registered in the names of the holders of
record of Right Certificates on the record date specified in the public announcement. 
 (j) Irrespective of any
adjustment or change in the Purchase Price or the number of one one-thousandths of a share of Preferred Stock issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Purchase
Price and the number of one one-thousandths of a share of Preferred Stock which were expressed in the initial Right Certificates issued hereunder. 
 (k) Before taking any action that would cause an adjustment reducing the Purchase Price below the then par value, if any, of the Preferred Stock or other shares of capital stock issuable upon exercise of
the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Preferred Stock or other such shares at
such adjusted Purchase Price. 

  
 21 

 (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event the issuing to the holder of any Right exercised after such record date of the Preferred
Stock and other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Preferred Stock and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase
Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional shares upon the
occurrence of the event requiring such adjustment. 
 (m) Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that it in its sole discretion shall determine to
be advisable in order that any consolidation or subdivision of the Preferred Stock, issuance wholly for cash of any shares of Preferred Stock at less than the current market price, issuance wholly for cash or Preferred Stock or securities which by
their terms are convertible into or exchangeable for Preferred Stock, dividends on Preferred Stock payable in shares of Preferred Stock or issuance of rights, options or warrants referred to hereinabove in Section 11(b), hereafter made
by the Company to holders of its Preferred Stock shall not be taxable to such stockholders. 
 (n) The Company
covenants and agrees that it shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof),
(ii) merge with or into any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one
transaction, or a series of related transactions, assets, cash flow or earning power aggregating more than 50% of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o) hereof), if at the time of or immediately after such consolidation, merger or sale there are any rights, warrants or other
instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights. 

(o) The Company agrees that, after the earlier of the Distribution Date or the Stock Acquisition Date, it will not, except
as permitted by Sections 23, 24 or 27 hereof, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or eliminate the
benefits intended to be afforded by the Rights. 
 (p) Anything in this Agreement to the contrary
notwithstanding, if at any time after the date of this Agreement and prior to the Distribution Date, the Company shall (i) declare or pay any dividend on the Common Stock payable in Common Stock or (ii) effect a subdivision, combination or
consolidation of the Common Stock (by reclassification or otherwise than by payment of a dividend payable in Common Stock) 

  
 22 

 
into a greater or lesser number of Common Stock, then in any such case, the number of Rights associated with each share of Common Stock then outstanding, or issued or delivered thereafter, shall
be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result obtained by multiplying the number of Rights associated with each share of Common Stock
immediately prior to such event by a fraction the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of
Common Stock outstanding immediately following the occurrence of such event. 
 Section 12. Certificate of Adjusted
Purchase Price or Number of Shares. Whenever an adjustment is made as provided in Section 11 hereof, the Company shall promptly (a) prepare a certificate setting forth such adjustment, and a brief statement of the facts
accounting for such adjustment, (b) file with the Rights Agent and with each transfer agent for the Common Stock or the Preferred Stock a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate
in accordance with Section 25 hereof (if so required under Section 25 hereof). The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained and shall not be deemed to
have knowledge of any such adjustment unless and until it shall have received such certificate. 
 Section 13.
[Intentionally Omitted] 
 Section 14. Fractional Rights and Fractional Shares. (a) The Company shall
not be required to issue fractions of Rights or to distribute Right Certificates which evidence fractional Rights (except prior to the Distribution Date in accordance with Section 11(p) hereof). In lieu of such fractional Rights, there
shall be paid to the registered holders of the Right Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For the purposes of
this Section 14(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing
price for any day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction
reporting system with respect to securities listed or admitted to trading on the NASDAQ or, if the Rights are not listed or admitted to trading on the NASDAQ, as reported in the principal consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing
bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors. If on any such date no such market maker is making a market in the Rights, the fair value of the Rights on such date
as determined in good faith by the Board of Directors shall be used. 

  
 23 

 (b) The Company shall not be required to issue fractions of Preferred Stock (other than
fractions which are integral multiples of one one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to distribute certificates which evidence fractional shares of Preferred Stock (other than fractions which are integral
multiples of one one-thousandth of a share of Preferred Stock). Interests in fractions of Preferred Stock in integral multiples of one one-thousandth of a share of Preferred Stock may, at the election of the Company, be evidenced by depositary
receipts, pursuant to an appropriate agreement between the Company and a depositary selected by it; provided, that such agreement shall provide that the holders of such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Stock represented by such depositary receipts. In lieu of fractional shares of Preferred Stock that are not integral multiples of one one-thousandth of a share of Preferred Stock, the
Company shall pay to the registered holders of Right Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one share of Preferred Stock. For the purposes of
this Section 14(b), the current market value of a share of Preferred Stock shall be the closing price of a share of Preferred Stock (as determined pursuant to Section 11(d)(i) hereof) for the Trading Day immediately prior to
the date of such exercise. 
 (c) Following the occurrence of a Section 11(a)(ii) Event, the Company shall not be
required to issue fractions of shares of Common Stock or to distribute certificates which evidence fractional shares of Common Stock upon the exercise or exchange of Rights. In lieu of such fractional shares of Common Stock, the Company shall pay to
the registered holders of the Right Certificates with regard to which such fractional shares of Common Stock would otherwise be issuable an amount in cash equal to the same fraction of the current market value of a whole share of Common Stock (as
determined in accordance with Section 14(a) hereof) for the Trading Day immediately prior to the date of such exercise or exchange. 
 (d) The holder of a Right by the acceptance of the Right expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right (except as provided above).

 Section 15. Rights of Action. All rights of action in respect of this Agreement, excepting the rights of action
given to the Rights Agent under Section 18 hereof, are vested in the respective registered holders of the Right Certificates (and, prior to the Distribution Date, the registered holders of the Common Stock); and any registered holder of
any Right Certificate (or, prior to the Distribution Date, of the Common Stock), without the consent of the Rights Agent or of the holder of any other Right Certificate (or, prior to the Distribution Date, of the Common Stock), on his own behalf and
for his own benefit, may enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Right Certificate (or, prior to the
Distribution Date, such Common Stock) in the manner provided in such Right Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of
Rights would not have an adequate remedy at law for any breach of this Agreement and 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. 

  
 24 

 Section 16. Agreement of Right 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
Stock; 
 (b) after the Distribution Date, the Right Certificates are transferable only on the registry books of
the Rights Agent if surrendered at the office or agency of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer; 

(c) subject to Section 6(a) and Section 7(f) hereof, the Company and the Rights Agent may deem and
treat the Person in whose name a Right Certificate (or, prior to the Distribution Date, the associated Common Stock certificate (or Book Entry shares in respect of Common Stock)) is registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or writing on the Right Certificates or the associated Common Stock certificate (or notices provided to holders of Book Entry shares of Common Stock) made by anyone other than the Company
or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent, subject to the last sentence of Section 7(e) hereof, shall be required to be affected by any notice to the contrary; and 

(d) notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any
liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree or ruling issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining
performance of such obligation; provided, however, the Company must use its reasonable best efforts to have any such order, decree or ruling lifted or otherwise overturned as soon as possible. 

Section 17. Right Certificate Holder Not Deemed a Stockholder. No holder, as such, of any Right Certificate shall be entitled
to vote, receive dividends or be deemed for any purpose the holder of the Preferred Stock or any other securities of the Company which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders
at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in this Agreement), or to receive dividends or subscription rights, or
otherwise, until the Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions hereof. 

  
 25 

 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 in accordance with a fee schedule to be mutually agreed upon and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other
disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability or
expense, incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs
and expenses of defending against any claim of liability in the premises. 
 (b) The Rights Agent shall be protected and shall
incur no liability for, or in respect of any action taken, suffered or omitted by it in connection with, its administration of this Agreement in reliance upon any Right Certificate or certificate for the Preferred Stock or Common Stock or for other
securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, instruction, 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 corporation into which the Rights Agent
or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation succeeding
to the corporate trust or stock transfer business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any
of the parties hereto; provided, that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 21 hereof. In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement, any of the Right 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 Right Certificates so
countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right 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 Right Certificates shall have the full force provided in the Right 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 Right Certificates shall have been countersigned but not delivered the Rights Agent may adopt the
countersignature under its prior name and deliver Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, the Rights Agent may countersign such Right Certificates either in its
prior name or in its changed name and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Agreement. 

  
 26 

 Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties and
obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Right Certificates, by their acceptance thereof, shall be bound: 

(a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the advice of such
counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion. 

(b) Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable
that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by any one of the President, any Vice President, the Treasurer, the Controller or the Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization to the
Rights Agent for any action taken or suffered in good faith by it under the provisions of this 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. 

(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 Right 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 under any responsibility in respect of the validity of this Agreement or the execution
and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Right Certificate; nor shall it be responsible for any change in the exercisability of the Rights (including the Rights becoming void pursuant to Section 7(e) hereof) or any
adjustment in the terms of the Rights (including the manner, method or amount thereof) provided for in Sections 3, 11, 23 and 27, 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 Right Certificates after receipt of a certificate furnished pursuant to Section 12, describing such change or adjustment); nor shall it by any act hereunder be deemed
to make any representation or warranty as to the authorization or reservation of any shares of Preferred Stock, Common Stock or other securities to be issued pursuant to this Agreement or any Right Certificate or as to whether any shares of
Preferred Stock, Common Stock or other securities 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 person reasonably believed by the Rights Agent to be one of the President, the Chief Financial Officer or the Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith in accordance with instructions of any such officer or for any delay in acting while waiting for those instructions. Any
application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken or omitted by the Rights Agent under this Agreement and the date on and/or after
which such action shall be taken or such omission shall be effective. The Rights Agent shall not be liable for any action taken by, or omission of, the Rights Agent in accordance with a proposal included in any such application on or after the date
specified in such application (which date shall not be less than five Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to an earlier date) unless,
prior to taking any such action (or the effective date in the case of an omission), the Rights Agent shall have received written instructions in response to such application specifying the action to be taken or omitted. 

(h) The Rights Agent and any stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in any
of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not
Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity. 

(i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty
hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from
any such act, default, neglect or misconduct, provided, however, that reasonable care was exercised in the selection and continued employment thereof. 

(j) At any time and from time to time after the Distribution Date, upon the request of the Company, the Rights Agent shall
promptly deliver to the Company a list, as of the most recent practicable date (or as of such earlier date as may be specified by the Company) of the holders of record of the Rights. 

(k) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty
hereunder through any corporate trust, stock issuance or stock transfer powers as may be reasonably determine is necessary for such purpose. 

  
 28 

 (l) No provision of this Agreement shall require the Rights Agent to expend
or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate
indemnification against such risk or liability is not reasonably assured to it. 
 (m) If, with respect to any
Right Certificate surrendered to the Rights Agent for exercise or transfer, the certificate contained in the form of assignment or the form of election to purchase set forth on the reverse thereof, as the case may be, has not been completed to
certify the holder is not an Acquiring Person (or an Affiliate or Associate 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 30 days’ notice in writing mailed to the Company and to each transfer agent of the Common Stock or Preferred Stock by registered or certified mail. The Company shall promptly notify the holders of the Right
Certificates by first-class mail of any such resignation following the Distribution Date. The Company may remove the Rights Agent or any successor Rights Agent upon 30 days’ notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Stock or Preferred Stock by registered or certified mail, and, following the Distribution Date, to the holders of the Right Certificates by first-class mail. If the Rights Agent
shall resign or be removed or shall otherwise become incapable of acting, the resigning, removed, or incapacitated Rights Agent shall remit to the Company, or to any successor Rights Agent designated by the Company, all books, records, funds,
certificates or other documents or instruments of any kind then in its possession which were acquired by such resigning, removed or incapacitated Rights Agent in connection with its services as Rights Agent hereunder, and shall thereafter be
discharged from all duties and obligations hereunder. Following notice of such removal, resignation or incapacity, the Company shall appoint a successor to such Rights Agent. If the Company shall fail to make such appointment within a period of 30
days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a Right Certificate (who shall, with such notice, submit his Right
Certificate for inspection by the Company), then the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company
or by such a court, shall be either (A) a corporation organized and doing business under the laws of the United States or of the State of New York or Texas (or any other state of the United States so long as such corporation is authorized to do
business as a banking institution in the State of New York or Texas), in good standing, having an office or an affiliate with an office in the State of New York which is authorized under such laws to exercise corporate trust or stock transfer powers
and is subject to supervision or examination by Federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50 million or (B) an affiliate of a corporation described in
clause (A) of this sentence which is a corporation organized and doing business under the laws of the United States or of the State of New York or Texas (or any other state of the United States so long as such corporation is authorized to do
business as a banking institution in the State of New York or Texas), in good standing, having a principal office in the State of New York, which 

  
 29 

 
is authorized under such laws to exercise corporate trust or stock transfer powers and is subject to supervision or examination by Federal or state authority. After appointment, the successor
Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor
Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock or Preferred Stock, and, following the Distribution Date, mail a notice thereof in writing to the registered holders of the Right 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 Right Certificates. Notwithstanding any of the provisions of this Agreement
or of the Rights to the contrary, the Company may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or
kind or class of shares or other securities or property purchasable under the Right Certificates made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of shares of Common Stock following the
Distribution Date and prior to the redemption or expiration of the Rights, the Company (a) shall, with respect to shares of Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement,
granted or awarded as of the Distribution Date, 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, issue
Right Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no such Right Certificate shall be issued if, and to the extent that, the Company shall be
advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Right Certificate would be issued, and (ii) no such Right 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 Board of Directors may, at its option, at any time prior to the earlier of (i) the close of business on the tenth day following the Stock Acquisition Date (or, if the Stock Acquisition Date shall have occurred
prior to the Record Date, the close of business on the twentieth day following the Record Date), 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 (the redemption price being hereinafter referred to as the “Redemption Price”). Notwithstanding anything
contained in this Agreement to the contrary, the Rights shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event until such time as the Company’s right of redemption hereunder has expired. The redemption of
the Rights may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on
the Current Market Price of the Common Stock at the time of redemption) or any other form of consideration deemed appropriate by the Board of Directors. 

  
 30 

 (b) Immediately upon the action of the Board of Directors ordering the redemption of the
Rights pursuant to paragraph (a) of this Section 23 (or at such later time as the Board of Directors may establish for the effectiveness of such redemption), 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; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Within 10 days after such action of the Board of Directors ordering the redemption of the
Rights (or such later time as the Board of Directors may establish for the effectiveness of such redemption), the Company shall mail a notice of redemption to all the holders of the then outstanding Rights at their last addresses as they appear upon
the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Stock. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of redemption shall state the method by which the payment of the Redemption Price will be made. 
 Section 24. Notice of Certain Events. (a) In case the Company shall at any time after the Distribution Date, propose (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of Preferred Stock (other than a regular quarterly cash dividend out of earnings or retained earnings of the Company), or (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares of Preferred Stock or shares of stock of any class or any other securities, rights or options, or (iii) to effect any reclassification of its Preferred Stock (other
than a reclassification involving only the subdivision of outstanding shares of Preferred Stock), or (iv) to effect any consolidation or merger into or with any other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer), in one transaction or a series of related transactions, of more than 50% of
the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with
Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Right Certificate, to the extent feasible and in accordance with
Section 25 hereof, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger,
sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the shares of Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any
action covered by clause (i) or (ii) above at least twenty (20) days prior to the record date for determining holders of the shares of Preferred Stock for purposes of such action, and in the case of any such other action, at least
twenty (20) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the shares of Preferred Stock, whichever shall be the earlier. (b) In case any event described in
Section 11(a)(ii) shall occur, then the Company shall as soon as practicable thereafter give to each holder of a Right Certificate (or if occurring prior to the Distribution Date, the holders of the Common Stock) in accordance with
Section 25 hereof, a notice of the occurrence of such event, which notice shall describe such event and the consequences of such event to holders of Rights under Section 11(a)(ii) hereof, and (ii) all references in the
preceding paragraph to Preferred Stock shall be deemed thereafter to refer to Class A Common Stock and/or, if appropriate, other securities. 

  
 31 

 (c) The failure to give any notice provided for herein shall not affect the validity or
enforceability of any action intended to be the subject thereof. 
 Section 25. Notices. Notices or demands
authorized by this Agreement to be given or made by the Rights Agent or by the holder of any Right Certificate to or on the Company shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is
filed in writing with the Rights Agent) as follows:

Subject to the provisions of Section 21 hereof, any notice or demand authorized by this Agreement to be given or made by the Company or by
the holder of any Right Certificate to or on the Rights Agent shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Company) as follows:

 Attention: General Counsel 
 Notices or demands authorized by this Agreement to be given or made by
the Company or the Rights Agent to the holder of any Right Certificate shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed to such holder at the address of such holder as shown on the registry books of the
Company. 
 Section 26. Supplements and Amendments. Except as otherwise provided in this Section 26, for
so long as the Rights are then redeemable, the Company may in its sole and absolute discretion, and the Rights Agent shall if the Company so directs, supplement or amend any provision of this Agreement in any respect without the approval of any
holders of the Rights. At any time when the Rights are no longer redeemable, except as otherwise provided in this Section 26, the Company may, and the Rights Agent shall, if the Company so directs, 

  
 32 

 
supplement or amend this Agreement without the approval of any holders of Right Certificates 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 or as required to comply with any change in applicable law, (iii) shorten or lengthen any time period hereunder, or (iv) change or supplement the provisions
hereunder in any manner which the Company may deem necessary or desirable; provided that no such supplement or amendment shall adversely affect the interests of the holders of Rights as such (other than an Acquiring Person or an Affiliate or
Associate of an Acquiring Person), and no such amendment may cause the rights again to become redeemable or cause the Agreement again to become amendable other than in accordance with this sentence. Notwithstanding anything contained in this
Agreement to the contrary, any supplement or amendment shall be made only upon approval by the Board of Directors. Upon the delivery of a certificate from an appropriate officer of the Company which states that the proposed supplement or amendment
is in compliance with the terms of this Section 26, the Rights Agent shall execute such supplement or amendment; provided, that any supplement or amendment other than to this Section 26 or Sections 18,
19, 20, 21 or 32 that does not amend this Agreement in a manner adverse to the Rights Agent shall become effective immediately upon execution by the Company, whether or not also executed by the Rights Agent. 

Section 27. Exchange. (a) The Company may, at its option, at any time after the Stock Acquisition Date, upon resolution
by the Board of Directors, exchange all or part of the then outstanding Rights (which shall not include Rights that have become void pursuant to the provisions of Section 7(e) hereof) for Common Stock at an exchange ratio of one share of
Common Stock per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date of this Agreement (such exchange ratio being hereinafter referred to as the “Section 27(a)(i) Exchange
Ratio”). Notwithstanding the foregoing, the Company may not effect such exchange at any time after any Acquiring Person, together with all Affiliates and Associates of such Acquiring Person, becomes the Beneficial Owner of shares of Common
Stock representing 50% or more of the voting power represented by the shares of Common Stock then outstanding. The exchange of the Rights by the Board of Directors may be made effective at such time, on such basis and with such conditions as the
Board of Directors in its sole discretion may establish. Prior to effecting an exchange pursuant to this Section 27, the Board of Directors may direct the Company to enter into a trust agreement in such form and with such terms as the
Board of Directors shall then approve (the “Trust Agreement”). If the Board of Directors so directs, the Company shall enter into the Trust Agreement and shall issue to the trust created by such agreement (the
“Trust”) all of the shares of Common Stock issuable pursuant to the exchange, and all Persons entitled to receive shares pursuant to the exchange shall be entitled to receive such shares (and any dividends or distributions made
thereon after the date on which such shares are deposited in the Trust) only from the Trust and solely upon compliance with the relevant terms and provisions of the Trust Agreement. 

(b) Immediately upon the action of the Board of Directors ordering the exchange of any Rights pursuant to Section 27(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 shares of Common Stock equal to the number of such
Rights held by such holder multiplied by the Section 27(a)(i) Exchange Ratio. The Company shall promptly give public notice of any such exchange; provided, however, that the failure to

  
 33 

 
give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their
last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the shares of Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of
Rights (other than Rights which have become void pursuant to the provisions of Section 7(e) hereof) held by each holder of Rights. 
 (c) If there shall not be sufficient shares of Common Stock issued but not outstanding or authorized but unissued (and unreserved) to permit any exchange of Rights as contemplated in accordance with this
Section 27, the Company shall make adequate provision to substitute, to the extent that there are insufficient shares of Common Stock available (1) cash, (2) other equity securities of the Company, (3) debt securities of
the Company, (4) other assets or (5) any combination of the foregoing, having an aggregate value per Right equal to the then current per share market price (determined pursuant to Section 11(d) hereof) of the Common Stock
multiplied by the Section 27(a)(i) Exchange Ratio, where such aggregate value has been determined by a majority of the members of the Board of Directors, after receiving advice from a nationally recognized investment banking firm. To the
extent that the Company determines that any such substitution must be made, the Company shall provide, subject to Section 7(e) hereof, that such substitution shall apply uniformly to all outstanding Rights. 

(d) The Company shall not be required to issue fractions of shares of Common Stock or to distribute certificates which evidence
fractional shares of Common Stock. In lieu of such fractional shares of Common Stock, the Company shall pay to the registered holders of the Right Certificates with regard to which such fractional shares of Common Stock would otherwise be issuable
an amount in cash equal to the same fraction of the current market value of a whole share of Common Stock. For the purposes of this Section 27(d), the current market value of a whole share of Common Stock shall be the closing price of a
share of Common Stock (as determined pursuant to the second sentence of Section 11(d) hereof) for the Trading Day immediately prior to the date of the exchange pursuant to this Section 27. 

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. 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 Right Certificates (and, prior to the Distribution Date, the Common Stock) any legal
or equitable right, remedy or claim under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Rights Agent and the registered holders of the Right Certificates (and, prior to the Distribution Date, the
Common Stock). 
 Section 30. Determinations and Actions by the Board of Directors. The Board of Directors shall
have the exclusive power and authority to administer this Agreement and to exercise the rights and powers specifically granted to the Board of Directors or to the Company, 

  
 34 

 
or as may be necessary or advisable in the administration of this Agreement, including, without limitation, the right and power to (i) interpret the provisions of this Agreement and
(ii) make all determinations deemed necessary or advisable for the administration of this Agreement (including, without limitation, a determination to redeem or not redeem the Rights or to amend this Agreement). All such actions, calculations,
interpretations and determinations that are done or made by the Board of Directors in good faith shall be final, conclusive and binding on the Company, the Rights Agent, the holders of the Rights, as such, and all other parties. 

Section 31. Severability. If any term, provision, covenant or restriction of this Agreement or applicable to 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 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 twentieth day following the date of such determination by the Board. 
 Section 32. Governing Law. This Agreement and each Right 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. 
 Section 33. Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such
counterparts shall together constitute but one and the same instrument. 
 Section 34. Descriptive Headings.
Descriptive headings of the several Sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

 EXHIBIT A 
 FORM OF 
 CERTIFICATE OF DESIGNATION 

OF 

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK 
 OF 
 INTEGRATED ELECTRICAL SERVICES, INC. 

(Pursuant to Section 151 of the 
 General Corporation Law of the State of Delaware) 
 Integrated Electrical
Services, Inc., a corporation organized and existing under the General Corporation Law of the State of Delaware (hereinafter called the “Company”), hereby certifies that the following resolution was duly adopted by the Board of
Directors of the Company as required by Section 151 of the General Corporation Law of the State of Delaware at a meeting duly called and held on January 24, 2013: 
 RESOLVED, that pursuant to the authority granted to and vested in the Board of Directors of the Company (hereinafter called the “Board of Directors” or the “Board”) in
accordance with the provisions of the Company’s Second Amended and Restated Certificate of Incorporation, as amended to date (hereinafter called the “Amended and Restated Certificate of Incorporation”), the Board of Directors
on January 24, 2013 adopted the following resolution creating a series of shares of Preferred Stock, par value $0.01 per share, designated as Series A Junior Participating Preferred Stock: 

RESOLVED, that pursuant to the authority vested in the Board of Directors of the Corporation in accordance with the provisions of the
Delaware General Corporation Law and the Certificate of Incorporation, a series of Preferred Stock of the Corporation be and it hereby is created, and that the designation and amount thereof and the powers, preferences and relative, participating,
optional and other special rights of the shares of such series, and the qualifications, limitations or restrictions thereof are as follows: 
 Section 1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” (the “Series A Preferred Stock”)
and the number of shares constituting the Series A Preferred Stock shall be 100,000. Such number of shares may be increased or decreased by resolution of the Board of Directors; provided, that no decrease shall reduce the number of shares of
Series A Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities
issued by the Company convertible into Series A Preferred Stock. 
 Section 2. Dividends and Distributions.

 (A) Subject to the rights of the holders of any shares of any series of Preferred Stock of the Company (the
“Preferred Stock”) (or any similar stock) ranking prior and superior to the Series A Preferred Stock with respect to dividends, the holders of shares of Series A Preferred 

  
 A-1

 
Stock, in preference to the holders of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”) and of any other stock of the Company ranking junior to the
Series A Preferred Stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the last day of January, April, July, and October in
each year (each such date being referred to herein as a “Dividend Payment Date”), commencing on the first Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $1.00 and (b) subject to the provision for adjustment hereinafter set forth, 1,000 times the aggregate per share amount of all cash dividends, and 1,000 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock, declared on the Common Stock since the immediately preceding Dividend Payment Date or, with respect to the
first Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Preferred Stock. If the Company shall at any time after January 24, 2013 (the “Rights Declaration Date”) declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each such case the amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under clause (b) of the preceding sentence
shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. 
 (B) The Company shall declare a dividend or distribution on the Series A
Preferred Stock as provided in paragraph Section 2(A) immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend
or distribution shall have been declared on the Common Stock during the period between any Dividend Payment Date and the next subsequent Dividend Payment Date, a dividend of $1.00 per share on the Series A Preferred Stock shall nevertheless be
payable, when, as and if declared, on such subsequent Dividend Payment Date. 
 (C) Dividends shall begin to accrue and be
cumulative, whether or not earned or declared, on outstanding shares of Series A Preferred Stock from the Dividend Payment Date next preceding the date of issue of such shares, unless the date of issue of such shares is prior to the record date for
the first 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 Dividend Payment Date or is a date after the record date for the determination of
holders of shares of Series A Preferred Stock entitled to receive a quarterly dividend and before such Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Dividend Payment Date. Accrued
but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be not more than 60 days prior to the date fixed for the payment thereof. 

  
 A-2

 Section 3. Voting Rights. The holders of shares of Series A Preferred Stock
shall have the following voting rights: 
 (A) Subject to the provision for adjustment hereinafter set forth and
except as otherwise provided in the Amended and Restated Certificate of Incorporation or required by law, each share of Series A Preferred Stock shall entitle the holder thereof to 1,000 votes on all matters upon which the holders of the Common
Stock of the Company are entitled to vote. If the Company shall at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock, then in each such case the number of votes per share to
which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately
after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 
 (B) Except as otherwise provided herein, in the Amended and Restated Certificate of Incorporation or in any other Certificate of Designations creating a series of Preferred Stock or any similar stock, and
except as otherwise required by law, the holders of shares of Series A Preferred Stock and the holders of shares of Common Stock and any other capital stock of the Company having general voting rights shall vote together as one class on all matters
submitted to a vote of stockholders of the Company. 
 (C) (i) If at any time dividends on any Series A Junior
Participating Preferred Stock shall be in arrears in an amount equal to six (6) quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a “default period”) which shall
extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Series A Junior Participating Preferred Stock then outstanding shall have been
declared and paid or set apart for payment. During each default period, all holders of Preferred Stock (including holders of the Series A Junior Participating Preferred Stock) with dividends in arrears in an amount equal to six (6) quarterly
dividends thereon, voting as a class, irrespective of series, shall have the right to elect two (2) Directors. 
 (ii) During any default period, such voting right of the holders of Series A Junior Participating Preferred Stock may be exercised initially at a special meeting called pursuant to this
Section 3(c)(ii) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders, provided that such voting right shall not be exercised unless the holders of ten percent (10%) in number of shares
of Preferred Stock outstanding shall be present in person or by proxy. The absence of a quorum of the 

  
 A-3

 
holders of Common Stock shall not affect the exercise by the holders of Preferred Stock of such voting right. At any meeting at which the holders of Preferred Stock shall exercise such voting
right initially during an existing default period, they shall have the right, voting as a class, to elect Directors to fill such vacancies, if any, in the Board of Directors as may then exist up to two (2) Directors or, if such right is
exercised at an annual meeting, to elect two (2) Directors from the class of Directors being elected at such annual meeting. If the number which may be so elected at any special meeting does not amount to the required number, the holders of the
Preferred Stock shall have the right to make such increase in the number of Directors in the class elected at the most recent annual meeting of stockholders as shall be necessary to permit the election by them of the required number. After the
holders of the Preferred Stock shall have exercised their right to elect Directors in any default period and during the continuance of such period, the number of Directors shall not be increased or decreased except by vote of the holders of
Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Junior Participating Preferred Stock. 

(iii) Unless the holders of Preferred Stock shall, during an existing default period, have previously exercised their
right to elect Directors, the Board of Directors may order, or any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Preferred Stock outstanding, irrespective of series, may
request, the calling of a special meeting of the holders of Preferred Stock, which meeting shall thereupon be called by the President, a Vice-President or the Secretary of the Corporation. Notice of such meeting and of any annual meeting at which
holders of Preferred Stock are entitled to vote pursuant to this Section 3(c)(iii) shall be given to each holder of record of Preferred Stock by mailing a copy of such notice to such holder at such holder’s last address as the same
appears on the books of the Company. Such meeting shall be called for a time not earlier than twenty (20) days and not later than sixty (60) days after such order or request, or in default of the calling of such meeting within sixty
(60) days after such order or request, such meeting may be called on similar notice by any stockholder or stockholders owning in the aggregate not less than ten percent (10%) of the total number of shares of Preferred Stock outstanding.
Notwithstanding the provisions of this Paragraph (c)(iii), no such special meeting shall be called during the period within sixty (60) days immediately preceding the date fixed for the next annual meeting of the stockholders. 

(iv) In any default period, the holders of Common Stock, and other classes of stock of the Company if applicable, shall
continue to be entitled to elect the whole number of Directors until the holders of Preferred Stock shall have exercised their right to elect two (2) Directors voting as a class, after the exercise of which right (x) the Directors so
elected by the holders of Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the Board of Directors may (except as
provided in Section 3(C)(ii)) be filled by vote of a majority of the remaining Directors theretofore elected by the holders of the class of stock which elected the Director whose office shall have become vacant. References in this
Section (C) to Directors elected by the holders of a particular class of stock shall include Directors elected by such Directors to fill vacancies as provided in clause (y) of the foregoing sentence. 

  
 A-4

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

Section 4. Certain Restrictions. 
 (A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not earned or declared, on shares of Series A Preferred Stock outstanding shall have been paid in full, the Company shall not: 

(i) declare or pay dividends, or make any other distributions, on any shares of stock ranking junior (as to dividends) to
the Series A Preferred Stock; 
 (ii) declare or pay dividends, or make any other distributions, on any shares of
stock ranking on a parity (as to dividends) with the Series A Preferred Stock, except dividends paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to
which the holders of all such shares are then entitled; 
 (iii) redeem or purchase or otherwise acquire for
consideration shares of any stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock, provided that the Company may at any time redeem, purchase or otherwise acquire shares
of any such junior stock in exchange for shares of any stock of the Company ranking junior (as to dividends and upon dissolution, liquidation or winding up) to the Series A Preferred Stock or rights, warrants or options to acquire such junior stock;

 (iv) redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either
as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, provided, that the Company may at any time redeem, purchase or otherwise acquire shares of any such parity stock in
exchange for shares of any stock of the Company ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series A Junior Participating Preferred Stock; or 

  
 A-5

 (v) redeem or purchase or otherwise acquire for consideration any shares of
Series A Preferred Stock, or any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except in accordance with a purchase offer made in writing or by
publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective
series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. 
 (B) The Company shall not permit any subsidiary of the Company to purchase or otherwise acquire for consideration any shares of stock of the Company unless the Company could, under
Section 4(A), purchase or otherwise acquire such shares at such time and in such manner. 
 Section 5.
Reacquired Shares. Any shares of Series A Preferred Stock purchased or otherwise acquired by the Company in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their
retirement become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to any conditions and restrictions on
issuance set forth herein. 
 Section 6. Liquidation, Dissolution or Winding Up. 

(a) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the Company, no distribution shall be made to the holders
of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Series A Junior Participating
Preferred Stock shall have received an amount equal to $100 per share of Series A Junior Participating Preferred Stock, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such
payment (the “Series A Liquidation Preference”). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the holders of shares of Series A Junior Participating
Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the “Common Adjustment”) equal to the quotient obtained by dividing (i) the Series A Liquidation Preference
by (ii) 1,000 (as appropriately adjusted as set forth in subparagraph (c) below to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock) (such number in clause (ii), the
“Adjustment Number”). Following the payment of the full amount of the Series A Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series A Junior Participating Preferred Stock and Common Stock,
respectively, holders of Series A Junior Participating Preferred Stock and holders of Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number (with respect to
such Preferred Stock) to 1 (with respect to such Common Stock) on a per share basis. 

  
 A-6

 (b) If, however, there are not sufficient assets available to permit payment
in full of the Series A Liquidation Preference and the liquidation preferences of all other series of Preferred Stock, if any, which rank on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior
Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets
available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock. 
 (c) If the Company shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or
(iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 

Section 7. Consolidation, Merger, etc. If the Company shall enter into any consolidation, merger, combination or other
transaction in which the shares of Common Stock are converted into, exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each share of Series A Preferred Stock shall at the same time be
similarly converted into, exchanged for or changed into an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 1,000 times the aggregate amount of stock, securities, cash and/or any other property (payable in
kind), as the case may be, into which or for which each share of Common Stock is converted, exchanged or converted. If the Company shall at any time after the Rights Declaration Date declares or pays any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of
shares of Common Stock, then in each such case the amount set forth in the preceding sentence with respect to the conversion, exchange or change of shares of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. 

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

Section 9. Rank. The Series A Preferred Stock shall rank, with respect to the payment of dividends and the distribution of
assets upon liquidation, dissolution or winding up of the Company, junior to all other series of Preferred Stock and senior to the Common Stock. 

  
 A-7

 Section 10. Amendment. If any proposed amendment to the Amended and Restated
Certificate of Incorporation (including this Certificate of Designations) would alter, change or repeal any of the preferences, powers or special rights given to the Series A Preferred Stock so as to affect the Series A Preferred Stock adversely,
then the holders of the Series A Preferred Stock shall be entitled to vote separately as a class upon such amendment, and the affirmative vote of a majority of the outstanding shares of the Series A Preferred Stock, voting separately as a class,
shall be necessary for the adoption thereof, in addition to such other vote as may be required by the General Corporation Law of the State of Delaware. 
 Section 11. Fractional Shares. Series A Preferred Stock may be issued in fractions of a share that 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 Preferred Stock.

transferee of any such Acquiring Person, Associate or Affiliate, or (iii) under certain circumstances specified in the Rights Agreement, a transferee of a person who, after such transfer, became an Acquiring Person, or an Affiliate or Associate
of an Acquiring Person, such Rights shall become null and void and no holder hereof shall have any right with respect to such Rights from and after the occurrence of such Section 11(a)(ii) Event. 

As provided in the Rights Agreement, the Purchase Price and the number and kind of shares of Preferred Stock or other securities, which
may be purchased upon the exercise of the Rights evidenced by this Right Certificate are subject to modification and adjustment upon the happening of certain events, including a Section 11(a)(ii) Event. 

This Right Certificate is subject to all of the terms, provisions and conditions of the Rights Agreement, which terms, provisions and
conditions are hereby incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the

 EXHIBIT C 
 UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS OWNED BY OR TRANSFERRED TO ANY PERSON WHO BECOMES AN ACQUIRING PERSON (AS DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN TRANSFEREES
THEREOF WILL BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE. 
 SUMMARY OF RIGHTS TO PURCHASE 

Shares of Preferred Stock 
 On January 24, 2013, the Board of Directors (the “Board”) of Integrated Electrical Services, Inc. (the “Company”) declared a dividend of one preferred share purchase
right (a “Right”) for each outstanding share of common stock, par value $0.01 per share, of the Company (the “Common Stock”). The dividend is payable to the stockholders of record as of the close of business on
February 19, 2013. Each Right represents a right to purchase one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share (“Preferred Stock”), of the Company at a price of $20.00 (as
the same may be adjusted, the “Purchase Price”). The description and terms of the Rights are set forth in a Tax Benefit Protection Plan Agreement (as the same may be amended from time to time, the “Rights
Agreement”) dated as of January 28, 2013, between the Company and American Stock Transfer & Trust Company, LLC, as Rights Agent (the “Rights Agent”). Capitalized terms used but not defined herein shall have
the meanings ascribed to such terms in the Rights Agreement. 
 The Board adopted the Rights Agreement in an effort to protect
stockholder value by attempting to protect against a possible limitation on the Company’s ability to use its net operating loss carryforwards (the “NOLs”) to reduce potential future federal income tax obligations. The Company
has experienced and continues to experience substantial operating losses. Under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules promulgated by the Internal Revenue Service, the Company may “carry
forward” these losses in certain circumstances to effect any current and future earnings, thereby reducing the Company‘s federal income tax liability, subject to certain requirements and restrictions. To the extent that the NOLs do not
otherwise become limited, the Company believes that it will be able to carry forward a significant amount of NOLs. As a result, the NOLs could be a substantial asset to the Company. However, if the Company experiences an “ownership
change”, as defined in Section 382 of the Code, its ability to use the NOLs will be substantially limited, and the timing of the usage of the NOLs could be substantially delayed, which could significantly impair the value of that asset.

 Distribution Date; Acquiring Persons, Transfer of Rights. Initially, the Rights will be attached to all Common Stock
certificates (or book entry shares) representing shares then outstanding, and no separate Right Certificates will be distributed. Subject to certain exceptions specified in the Rights Agreement, the Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) ten (10) days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired, or obtained the right to
acquire, beneficial ownership of 4.95% or more of the outstanding shares of Common Stock (the “Stock Acquisition Date”) and (ii) ten (10)

  
 C-1

 
business days following the commencement of, or the first public announcement of a person’s intention to commence, a tender offer or exchange offer that would result in a person or group
beneficially owning 4.95% or more of the outstanding shares of Common Stock. The definition of Acquiring Person excludes any Exempt Person (as defined below) and any person who would become an Acquiring Person solely as a result of an Exempt
Transaction (as defined below). Until the Distribution Date, (i) the Rights will be evidenced by the Common Stock certificates (or book entry shares in respect of the Common Stock) and will be transferred with and only with such Common Stock
certificates (or book entry shares in respect of the Common Stock), (ii) new Common Stock certificates (or book entry shares in respect of the Common Stock) after the Record Date will contain a notation incorporating the Rights Agreement by
reference and, with respect to any uncertificated book entry shares issued after the Record Date, proper notice will be provided that incorporates the Rights Agreement by reference and (iii) the surrender for transfer of any certificates for
Common stock (or book entry shares of Common Stock) outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such certificate or book entry shares. 

As soon as practicable after the Distribution Date, Right Certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date. Thereafter, the separate Right Certificates alone will represent the Rights. Except as otherwise determined by the Board, only shares of Common Stock issued prior to the Distribution Date will be issued
with Rights. 
 Exempt Persons. The following persons shall be “Exempt Persons” under the Rights Agreement:

 (i) Any person who, together with its Affiliates and Associates, is the Beneficial Owner of Common Stock, options and/or
warrants exercisable for shares of Common Stock representing 4.95% or more of the shares of Common stock outstanding on January 24, 2013 will be an “Exempt Person.” However, any such person will no longer be treated as an Exempt
Person and will be deemed an Acquiring Person if such person, together with its Affiliates and Associates, thereafter becomes the Beneficial Owner of securities representing a percentage of the outstanding Common Stock that exceeds by one-half of
one percent (0.5%) or more the lowest percentage of Common Stock Beneficially Owned by such person at any time since January 24, 2013, excluding increases in percentage ownership of Common Stock attributable to any (x) grant or adjustment
of an equity compensation award to such person by the Company or (y) repurchase or redemption of Common Stock by the Company. 
 (ii) In addition, any person who, together with its Affiliates and Associates, becomes the Beneficial Owner of Common Stock, options and/or warrants exercisable for shares of Common Stock representing
4.95% or more of the shares of Common Stock then outstanding because of a reduction in the number of outstanding shares of Common Stock as the result of a purchase of Common Stock by the Company or any of its subsidiaries will also be an
“Exempt Person.” However, any such person will no longer be treated as an Exempt Person and will be deemed an Acquiring Person if such person, together with its Affiliates and Associates, thereafter becomes the Beneficial Owner, of a
percentage of the outstanding Common Stock Beneficially Owned by such person at any time since such person first Beneficially Owned 4.95% or more of the Common Stock, excluding increases in percentage ownership of Common Stock attributable to any
(x) grant or adjustment of an equity compensation award to such person by the Company or (y) repurchase or redemption of shares of Common Stock by the Company. 

  
 C-2

 (iii) In addition, any person who, together with its Affiliates and Associates, is the
Beneficial Owner of Common Stock, options and/or warrants exercisable for shares of Common Stock representing 4.95% or more of the outstanding Common Stock, and whose Beneficial Ownership is determined by the Board, in its sole discretion,
(x) not to jeopardize or endanger the unrestricted availability to the Company of its Tax Benefits or (y) to be in the best interests of the Company, will be an “Exempt Person.” However, any such person shall no longer be treated
as an Exempt Person and will be deemed an Acquiring Person if (A) such person, together with its Affiliates and Associates, thereafter becomes the Beneficial Owner of a percentage of Common Stock that exceeds by one-half of one percent (0.5%)
or more the lowest percentage of Common Stock beneficially owned by such person at any time since such person first beneficially owned 4.95% or more of the Common Stock, excluding increases in Beneficial Ownership of Common Stock attributable to any
(I) grant or adjustment of an equity compensation award to such person by the Company or (II) repurchase or redemption of Common Stock by the Company, or (B) the Board, in its sole discretion, determines that such person’s Beneficial
Ownership (together with its Affiliates and Associates) may jeopardize or endanger the unrestricted availability to the Company of its Tax Benefits or not be in the best interests of the Company. 

A purchaser, assignee or transferee of shares of Common Stock (or options or warrants exercisable for Common Stock) from an Exempt Person
will not thereby become an Exempt Person, except that a transferee who receives Common Stock as a bequest or inheritance from the estate of an Exempt Person shall be an Exempt Person so long as such transferee continues to be the Beneficial Owner of
4.95% or more of the then outstanding shares of Common Stock. 
 Exempt Transactions. The following transactions shall be
“Exempt Transactions” under the Rights Agreement: any transaction that the Board determines, in its sole discretion, is exempt from the Rights Agreement, which determination shall be made in the sole and absolute discretion of the Board
prior to the date of such transaction, including, without limitation, if the Board determines that (i) neither the Beneficial Ownership of shares of Common Stock by any person, directly or indirectly, as a result of such transaction nor any
other aspect of such transaction would jeopardize or endanger the unrestricted availability to the Company of the Company’s Tax Benefits or (ii) such transaction is otherwise in the best interests of the Company. In granting an exemption
for an “Exempt Transaction,” the Board may require any person who would otherwise be an Acquiring Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or
undertakings will result in such consequences and subject the person to such conditions as the Board may determine in its sole discretion, including that any such violation shall result in such person becoming an Acquiring Person. 

Exercisability; Expiration. The Rights are not exercisable until the Distribution Date and will expire on the earliest of
(i) the close of business on December 31, 2017, (ii) the close of business on December 31, 2015 if stockholder approval of the Rights Agreement has not been received by or on such date, (iii) adjournment of the third annual
meeting of stockholders of the Company after the date of the Rights Agreement if stockholder approval of the Rights 

  
 C-3

 
Agreement has not been received by such date, (iv) the repeal of Section 382 of the Code and any successor statute or any other change of law if, as a result of such change of law, the
Board determines that the Rights Agreement is no longer necessary or desirable for the preservation of certain tax benefits, and (v) the beginning of the first taxable year of the Company to which the Board determines that certain tax benefits
may not be carried forward. At no time will the Rights have any voting power. 
 If, an Acquiring Person becomes the beneficial
owner of 4.95% or more of the outstanding shares of Common Stock, each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company), having
a value equal to two times the exercise price of the Right. The exercise price is the Purchase Price times the number of shares of Common Stock associated with each Right (initially, one). Notwithstanding any of the foregoing, following the
occurrence of an Acquiring Person becoming such (a “Flip-In Event”), all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null and void.
However, Rights are not exercisable following the occurrence of a Flip-In Event until such time as the Rights are no longer redeemable by the Company as set forth below. 
 For example, at an exercise price of $20.00 per Right, each Right distributed in respect of shares of Common Stock not owned by an Acquiring Person (or by certain related parties) following a Flip-In
Event would entitle its holder to purchase $40.00 worth of Common Stock (or other consideration, as noted above) for $20.00. If the Common Stock at the time of exercise had a market value per share of $4.00 per share, the holder of each valid Right
would be entitled to purchase 10 shares of Common Stock for $20.00. 
 Until a Right is exercised, the holder thereof, as such,
will have no rights as a shareholder of the Company, including, without limitation, the right to vote or to receive dividends. While the distribution of the Rights will not be taxable to shareholders or to the Company, shareholders may, depending
upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Common Stock (or other consideration) of the Company as set forth above or in the event the Rights are redeemed. 

Anti-Dilution Provisions. The Purchase Price payable, and the number of shares of Preferred Stock or other securities or property
issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Preferred Stock, (ii) if holders of
the Preferred Stock are granted certain rights or warrants to subscribe for Preferred Stock or convertible securities at less than the then-current market price of the Preferred Stock, or (iii) upon the distribution to holders of the Preferred
Stock of evidences of indebtedness or assets (excluding regular quarterly cash dividends) or of subscription rights or warrants (other than those referred to above). 
 With certain exceptions, no adjustments in the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price. No fractional shares will be issued and, in lieu
thereof, an adjustment in cash will be made based on the market price of the Preferred Stock on the last trading date prior to the date of exercise. 

  
 C-4

 Exchange. At any time after the Stock Acquisition Date, the Board may exchange the
Rights (other than Rights owned by an Acquiring Person), in whole or in part, at an exchange ratio equal to one (1) share of Common Stock per Right (subject to adjustment). 

Redemption. At any time until ten (10) days following the Stock Acquisition Date, the Company may redeem the Rights in whole,
but not in part, at a price of $0.001 per Right. Immediately upon action by the Board ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the $0.001 redemption price.

 Amendments. Other than those provisions relating to the principal economic terms of the Rights, any of the provisions
of the Rights Agreement may be amended by the Board prior to the Distribution Date. After the Distribution Date, the provisions of the Rights Agreement may be amended by the Board in order to cure any ambiguity, to make changes which do not
adversely affect the interests of holders of Rights (excluding the interests of any Acquiring Person), or to shorten or lengthen any time period under the Rights Agreement; provided, however, that no amendment to lengthen the time
period governing redemption shall be made at such time as the Rights are not redeemable. 
 A copy of the Rights Agreement has
been filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A. A copy of the Rights Agreement is available free of charge from the Company. This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement, as the same may be amended from time to time, which is hereby incorporated herein by reference.
