 TAX BENEFIT PRESERVATION PLAN 

Tax Benefit Preservation Plan, dated as of February 13, 2013 (this “Plan”), between US AIRWAYS
GROUP, INC., a Delaware corporation (the “Company”), and AMERICAN STOCK TRANSFER & TRUST COMPANY, LLC, a New York limited liability trust company, as Rights Agent (the “Rights Agent”).

 RECITALS 
 WHEREAS, the Company intends to execute and become a party to that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of the date hereof, among AMR Corporation
(“AMR”), AMR Merger Sub, Inc. and the Company; 
 WHEREAS, on February 13, 2013, the Board
of Directors (the “Board”) of the Company, in connection with approval of the Merger Agreement, adopted this Plan, and has authorized and declared a dividend of one common stock purchase right (a “Right”) for each
share of Common Stock (as defined in Section 1.6) of the Company outstanding at the close of business on February 27, 2013 (the “Record Date”) and has authorized and directed the issuance of one Right (subject to
adjustment as provided herein) with respect to each share of Common Stock that shall become outstanding between the Record Date and the earliest of the Distribution Date and the Expiration Date (as such terms are defined in Sections 3.1 and
7.1, respectively), each Right initially representing the right to purchase one tenth (subject to adjustment) of a share of Common Stock of the Company, upon the terms and subject to the conditions hereinafter set forth; provided,
however, that Rights may be issued with respect to Common Stock that shall become outstanding after the Distribution Date and prior to the Expiration Date in accordance with Section 22; 

WHEREAS, each of AMR and the Company view their respective Tax Benefits (as defined herein) available under the Internal
Revenue Code of 1986, as amended from time to time (the “Code”), as material assets of each constituent to the Merger Agreement and of the combined enterprise (the “Combined Enterprise”) to be created upon the
consummation of the transactions contemplated by the Merger Agreement, and have reached certain agreements reflected in the Merger Agreement to preserve the ability to utilize the Tax Benefits to the Combined Enterprise; and 

WHEREAS, in order to best preserve the ability to utilize such Tax Benefits, the Company has determined that it is in its
best interests and those of its stockholders to provide for the protection of the Tax Benefits on the terms and subject to the conditions set forth herein. 
 NOW, THEREFORE, in consideration of the premises and the mutual agreements herein set forth, the parties hereby agree as follows: 
 Section 1. Certain Definitions. For purposes of this Plan, the following terms have the meanings indicated: 
 1.1. “Acquiring Person” shall mean any Person who or which, from and after the date of this Plan, is or becomes a Substantial Stockholder, whether or not such Person continues to be a
Substantial Stockholder, but shall not include (i) an Exempt Person or (ii) any 

 
Existing Holder, unless and until such time as, after the first public announcement of this Agreement, the Percentage Stock Ownership of such Existing Holder shall be increased (other than
pursuant to a dividend or distribution paid or made by the Company on the outstanding Common Stock in Common Stock or pursuant to a split or subdivision of the outstanding Common Stock), unless upon such increase in the Percentage Stock Ownership,
such Existing Holder is not a Substantial Stockholder. 
 Notwithstanding the foregoing, no Person shall become an
“Acquiring Person” as the result of an acquisition of Common Stock by the Company which, by reducing the number of shares outstanding, increases the Percentage Stock Ownership of such Person; provided, however, that if a Person
shall become a Substantial Stockholder solely by reason of share purchases by the Company and shall, after such share purchases by the Company, increase its Percentage Stock Ownership in the Company (other than pursuant to a dividend or distribution
paid or made by the Company on the outstanding Common Stock in Common Stock or pursuant to a split or subdivision of the outstanding Common Stock), then such Person shall be deemed to be an “Acquiring Person” unless, upon such increase in
Percentage Stock Ownership, such Person is not a Substantial Stockholder. 
 Notwithstanding the foregoing, if the Board
determines in good faith that a Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this Section 1.1, has become such inadvertently (including, without limitation, because
(A) such Person was unaware that its Percentage Stock Ownership was sufficient to cause such Person to be an “Acquiring Person” or (B) such Person was aware of the extent of its Percentage Stock Ownership but had no actual
knowledge of the consequences of such Percentage Stock Ownership under this Plan), and such Person divests as promptly as practicable (as determined, in good faith, by the Board) a sufficient number of shares of Common Stock so that such Person
would no longer be an Acquiring Person, as defined pursuant to the foregoing provisions of this Section 1.1 (provided that such divestiture may be subject to terms and conditions satisfactory to the Board, including, without limitation,
the disgorgement of any profit attributable to the Beneficial Ownership of the Common Stock being divested), then such Person shall not be deemed to be or have become an “Acquiring Person” at any time for any purposes of this Plan. For all
purposes of this Plan, any calculation of the number of shares of Common Stock outstanding at any particular time, including for purposes of determining the Percentage Stock Ownership of any Person, shall be made pursuant to and in accordance with
Section 382 and the Treasury Regulations promulgated thereunder. 
 1.2. “Affiliate” and
“Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as in effect on
the date of this Plan and, to the extent not included within the foregoing, shall also include, with respect to any Person, any other Person whose Stock or other securities (i) would be deemed constructively owned by such first Person for
purposes of Section 382 (without regard to the rule that treats stock of an entity as to which the constructive ownership rules apply as no longer owned by that entity), (ii) would be deemed owned by a single “entity” as defined
in Treasury Regulation § 1.382-3(a)(1) in which both such first Person and such other Person are included or (iii) otherwise would be deemed aggregated with the Stock or other securities owned by such first Person pursuant to the
provisions of Section 382.

 1.3. A Person shall be deemed the “Beneficial Owner” of and
shall be deemed to “Beneficially Own” or have “Beneficial Ownership” of any securities (i) which such Person directly owns or (ii) which such Person would be deemed to constructively own (without regard to
the rule that treats stock of an entity as to which the constructive ownership rules apply as no longer owned by that entity) pursuant to Section 382 and the Treasury Regulations promulgated thereunder. 

1.4. “Business Day” shall mean any day other than a Saturday, Sunday, or a day on which banking
institutions in the State of New York are authorized or obligated by law or executive order to close. 
 1.5.
“close of business” on any given date shall mean 5:00 p.m., New York time, on such date; provided, however, that if such date is not a Business Day it shall mean 5:00 p.m., New York time, on the next succeeding Business Day.

 1.6. “Common Stock” when used with reference to the Company shall mean the Common Stock, par
value $0.01 per share, of the Company. “Common Stock” when used with reference to any Person other than the Company shall mean the capital stock with the greatest voting power, or the equity securities or other equity interest having power
to control or direct the management of, such other Person or, if such Person is a Subsidiary of another Person, the Person or Persons which ultimately control such first-mentioned Person, and which has issued and outstanding such capital stock,
equity securities or equity interest. 
 1.7. “Company Securities” means (i) shares of
Common Stock, (ii) shares of preferred stock (other than preferred stock described in Section 1504(a)(4) of the Code or treated as so described pursuant to Treasury Regulation § 1.382–2(a)(3)(i)), (iii) warrants, rights, or
options (including options within the meaning of Treasury Regulation § 1.382-2T(h)(4)(v)) to purchase stock of the Company, and (iv) any other interest that would be treated as “stock” of the Company pursuant to Treasury
Regulation § 1.382-2T(f)(18).
 1.8. “Exempt Person” shall mean (i) the Company and
any Subsidiary of the Company, in each case including, without limitation, the officers and members of the boards of directors thereof acting in their fiduciary capacities, or any employee benefit plan of the Company or of any Subsidiary of the
Company or any entity or trustee holding (or acting in a fiduciary capacity in respect of) shares of capital stock of the Company for or pursuant to the terms of any such plan, or for the purpose of funding other employee benefits for employees of

the adoption of this Plan, is a Substantial Stockholder.

that (i) for purposes of applying Treasury Regulation § 1.382–2T(k)(2), the Company shall be treated as having “actual knowledge” of the beneficial ownership of all outstanding Company Securities

  
 3 

 
that would be attributed to any individual or entity, and (ii) for the sole purpose of determining the Percentage Stock Ownership of any entity (and not for the purpose of determining the
Percentage Stock Ownership of any other Person), Company Securities held by such entity shall not be treated as no longer owned by such entity pursuant to Treasury Regulation § 1.382–2T(h)(2)(i)(A). 

1.11. “Person” shall mean any individual, partnership, joint venture, limited liability company, firm,
corporation, unincorporated association or organization, trust or other entity, or any group of such “Persons” having a formal or informal understanding among themselves to make a “coordinated acquisition” of shares within the

 Section 2. Appointment of Rights Agent. The Company hereby appoints
the Rights Agent to act as rights agent for the Company and the holders of the Rights (who, in accordance with Section 3, shall prior to the Distribution Date, also be the holders of the 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. In the event the Company appoints one or more co-rights agents, the
respective duties of the Rights Agent and any such other rights agents shall be as the Company shall determine. Contemporaneously with such appointment, if any, the Company shall notify the Rights Agent thereof. 

Section 3. Issuance of Right Certificates. 

3.1. Rights Evidenced by Stock Certificates. Until the close of business on the tenth
(10th) Business Day after the Stock Acquisition Date
(the “Distribution Date”), (x) the Rights (unless earlier expired, redeemed or terminated) will be evidenced (subject to the provisions of Section 3.2) by the certificates for Common Stock registered in the names of
the holders thereof or, in the case of uncertificated Common Stock registered in book entry form (“Book Entry Shares”), by notation in book entry (which certificates for Common Stock and Book Entry Shares shall also be deemed to be
Right Certificates) and not by separate certificates, and (y) the Rights (and the right to receive certificates therefor) will be transferable only in connection with the transfer of the underlying Common Stock. The preceding sentence
notwithstanding, prior to the occurrence of a Distribution Date (or such later Distribution Date as the Board may select pursuant to this sentence), the Board may postpone, one or more times, the Distribution Date in order to make a determination
pursuant to Sections 7.1(v), 7.1(vi), 28 or 29. As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign and the Company (or, if requested, the Rights
Agent) will send, by first-class, 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 Affiliate or Associate of an Acquiring Person), at the address
of such holder shown on the records of the Company or the transfer agent or registrar for the Common Stock, one or more certificates for Rights, in substantially the form of Exhibit A 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. 

3.2. Summary of Rights. On the Record Date or as soon as practicable thereafter, the Company will send or cause to
be sent a copy of a Summary of Rights to Purchase Common Stock, in substantially the form attached hereto as Exhibit B (the “Summary of Rights”), by first-class, postage-prepaid mail, to each record holder of Common Stock as
of the close of business on the Record Date (other than any Acquiring Person or any Affiliate or Associate of any Acquiring Person) at the address of such holder shown on the records of the Company or the transfer agent or registrar for the Common
Stock. Any failure to send a copy of the Summary of Rights shall not invalidate the Rights or affect their transfer with the Common Stock. With respect to certificates representing Common Stock and Book Entry Shares outstanding as of the close of
business on the Record Date, until the Distribution Date (or the earlier Expiration Date), the Rights will be evidenced by such certificates for Common Stock registered in the names of the holders thereof or Book Entry Shares, as applicable,
together with a copy of the Summary of Rights and the registered holders of the Common Stock shall also be registered holders of the associated Rights. Until the Distribution Date (or the earlier Expiration Date), the surrender for transfer of any
certificate for Common Stock or Book Entry Shares outstanding at the close of business on the Record Date, 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 and the Book Entry Shares, as applicable. 

  
 6 

 3.3. New Certificates and Uncertificated Shares After Record Date.
Certificates for Common Stock that become outstanding (whether upon issuance out of authorized but unissued Common Stock, disposition out of treasury or transfer or exchange of outstanding Common Stock) after the Record Date but prior to the
earliest of the Distribution Date or the Expiration Date, or in certain circumstances provided in Section 22 hereof, after the Distribution Date, shall have impressed, printed, stamped, written or otherwise affixed onto them a legend in
substantially the following form: 
 This certificate also evidences and entitles the holder
hereof to certain rights as set forth in a Tax Benefit Preservation Plan between US Airways Group, Inc. (the “Company”) and American Stock Transfer & Trust Company, LLC, as Rights Agent, dated as of February 13, 2013,
as the same may be amended from time to time (the “Plan”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances,
as set forth in the Plan, such Rights (as defined in the Plan) will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Company will mail to the holder of this certificate a copy of the Plan without charge
after receipt of a written request therefor. As described in the Plan, Rights which are owned by, transferred to or have been owned by Acquiring Persons (as defined in the Plan) or any Affiliate or Associate (as defined in the Plan) of any
Acquiring Person shall become null and void and will no longer be transferable. 
 With respect to any Book Entry
Shares, such legend shall be included in a notice to the record holder of such shares in accordance with applicable law. Until the Distribution Date (or the earlier Expiration Date), the Rights associated with the Common Stock represented by such
certificates and such Book Entry Shares shall be evidenced solely by such certificates or the Book Entry Shares alone, and the surrender for transfer of any such certificates or Book Entry Shares, 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 Record Date but prior to the Distribution Date, any Rights
associated with such Common Stock shall be deemed canceled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common Stock that are no longer outstanding. 

Notwithstanding this Section 3.3, neither the omission of the legend required hereby, nor the failure to
provide the notice thereof, shall affect the enforceability of any part of this Plan or the rights of any holder of the Rights. 

  
 7 

 Section 4. Form of Right Certificates. The Right Certificates
(and the forms of election to purchase shares and assignment, including the certifications therein, to be printed on the reverse thereof) shall each be substantially in the form set forth in Exhibit A 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 Plan, or as may be required to comply with any applicable law or
with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or trading system on which the Rights may from time to time be listed or quoted, or to conform to usage. Subject to the terms and conditions
hereof, the Right Certificates, whenever issued, shall be dated as of the Record Date, and shall show the date of countersignature by the Rights Agent, and on their face shall entitle the holders thereof to purchase such number of one tenths of a
share of Common Stock as shall be set forth therein at the price per one tenth of a share of Common Stock set forth therein (the “Purchase Price”), but the number of such one tenths of a share of Common Stock and the Purchase Price
shall be subject to adjustment as provided herein. 
 Section 5. Countersignature and Registration.
The Right Certificates shall be executed on behalf of the Company by the Chief Executive Officer, the President, any Executive Vice President and/or any such other officers of the Company as any of them may designate, either manually or by facsimile
signature, and shall have affixed thereto the Company’s seal or a facsimile thereof which shall be attested by the Secretary or any Assistant Secretary of the Company or by such officers as the Board may designate, either manually or by
facsimile signature. The Right Certificates shall be countersigned, either manually or by facsimile signature, by an authorized signatory of the Rights Agent, but it shall not be necessary for the same signatory to countersign all of the Right
Certificates hereunder. No Right Certificate shall be valid for any purpose unless so 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 Plan any such Person was not such an officer. 
 Following the Distribution Date, the Rights Agent will keep or cause to be kept, at its principal office, 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, the certificate number of 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. Subject to the provisions of this Plan, including, but not limited to, Section 11.1.2 and Section 14, at any time after the close of business on the Distribution
Date, and at or prior to the close of business on the Expiration Date, any Right Certificate or Right Certificates (other than Right Certificates representing Rights that have become null and void pursuant to Section 11.1.2 or that have
been exchanged pursuant to Section 27) may be transferred, split up, combined or exchanged for another Right 

  
 8 

 
Certificate or Right Certificates, entitling the registered holder to purchase a like number of one tenths of a share of Common Stock 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 shall make such request in writing delivered to the Rights Agent, and shall surrender, together with any required
form of assignment and certificate duly executed and properly completed, the Right Certificate or Right Certificates to be transferred, split up or combined or exchanged at the office of the Rights Agent designated for such purpose. Neither the
Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Right Certificate or Right Certificates until the registered holder shall have properly completed and duly executed
the certificate contained in the form of assignment on the reverse side of such Right Certificate or Right Certificates and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) thereof or
any Affiliate or Associate of such registered holder or such Beneficial Owner (or such former Beneficial Owner), in each case, 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 from the holders of Right Certificates of a sum sufficient to cover any tax or charge that may be imposed in connection with any
transfer, split up or combination or exchange of such Right Certificates. 
 Subject to the provisions of
Section 11.1.2, at any time after the Distribution Date and prior to the 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 countersignature and delivery to the registered
owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated. 
 Section 7. Exercise
of Rights; Purchase Price; Expiration Date of Rights. 
 7.1. Exercise of Rights. Subject to
Section 11.1.2 and except as otherwise provided herein, the registered holder of any Right Certificate may exercise the Rights evidenced thereby 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 certification on the reverse side thereof properly completed and duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the
aggregate Purchase Price for the total number of one tenths of a share of Common Stock (or other securities, cash or other assets) as to which the Rights are exercised, at or prior to the time (the “Expiration Date”) that is the
earliest of (i) the close of business on February 13, 2014 (the “Final Expiration Date”), (ii) the time at which the Rights are redeemed as provided in Section 23, (iii) immediately prior to the
closing of any merger or other acquisition transaction involving the Company pursuant to an agreement of the type described in Section 13.3, other than the Merger Agreement, at which time the Rights are deemed terminated, (iv) the
time at which the Rights are exchanged as provided in Section 27, (v) the close of business on the effective date of the repeal of Section 382 if the Board determines that this Plan is no longer necessary or desirable for the
preservation of the Tax 

  
 9 

 
Benefits, (vi) the time at which the Board determines that the Tax Benefits are fully utilized or no longer available under Section 382 or that an ownership change under
Section 382 would not adversely impact in any material respect the time period in which the Company or any successor or the Combined Enterprise could use the Tax Benefits, or materially impair the amount of the Tax Benefits that could be used
by the Company or any successor or the Combined Enterprise in any particular time period, for applicable tax purposes, (vii) the time at which the Merger Agreement is terminated, or (viii) notwithstanding anything contained herein to the
contrary, immediately prior to the occurrence of the Effective Time (as defined in the Merger Agreement). 

7.2. Purchase. The Purchase Price for each one tenth of a share of Common Stock pursuant to the exercise of a
Right shall be initially $3.00 (equivalent to $30.00 for each whole share of Common Stock), shall be subject to adjustment from time to time as provided in Sections 11, 13 and 26 and shall be payable in lawful money of the
United States of America in accordance with Section 7.3. 
 7.3. Payment Procedures. Except
as otherwise provided herein, upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase and certification properly completed and duly executed, accompanied by payment of the aggregate Purchase Price
for the total number of one tenths of a share of Common Stock to be purchased and an amount equal to any applicable tax or charge required to be paid by the holder of such Right Certificate in accordance with Section 9, in cash or by
certified or cashier’s check or money order payable to the order of the Company, the Rights Agent shall thereupon promptly (i)(A) requisition from any transfer agent of the Common Stock (or make available, if the Rights Agent is the transfer
agent) certificates for the number of shares of Common Stock to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests, or (B) if the Company shall have elected to deposit the total number
of shares of Common Stock issuable upon exercise of the Rights hereunder with a depositary agent, requisition from such depositary agent depositary receipts representing interests in such number of one tenths of a share of Common Stock as are to be
purchased (in which case certificates for the Common Stock represented by such receipts shall be deposited by the transfer agent with such depositary agent) and the Company hereby directs such depositary agent to comply with all such requests;
(ii) when appropriate, requisition from the Company the amount of cash to be paid in lieu of the issuance of fractional shares in accordance with Section 14 or otherwise in accordance with Section 11.1.3;
(iii) promptly after receipt of such certificates or depositary receipts, cause the same to be delivered to the registered holder of such Right Certificate, 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 the registered holder of such Right Certificate, or upon the order of the registered holder of such Right
Certificate, to such other Person as designated by such holder. In the event that the Company is obligated to issue other securities of the Company, pay cash and/or distribute other property pursuant to Section 11.1.3, 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. 

7.4. Partial Exercise. 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 Rights remaining unexercised shall be issued by the Rights Agent and delivered to the registered holder of such Right Certificate or to his or her duly authorized
assigns, subject to the provisions of Section 14. 

  
 10 

 7.5. Full Information Concerning Ownership. Notwithstanding anything
in this Plan 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 or as set forth in this Section 7 unless the certification contained in the form of election to purchase set forth on the reverse side of the Right Certificate surrendered for such exercise shall have been properly
completed and duly executed by the registered holder thereof and the Company shall have been provided with such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) thereof or any Affiliate or Associate of such
registered holder or such Beneficial Owner (or such former Beneficial Owner), in each case, as the Company shall reasonably request. 
 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 canceled form, or, if surrendered to the Rights Agent, shall be canceled by it, and no Right Certificates shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Plan. 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. Subject to applicable law and regulation, the Rights Agent shall maintain in a retrievable database electronic records or physical records of all cancelled or destroyed Rights Certificates which have
been cancelled or destroyed by the Rights Agent. The Rights Agent shall maintain such electronic records or physical records for the time period required by applicable law and regulation. Upon written request of the Company (and at the expense of
the Company), the Rights Agent shall provide to the Company or its designee copies of such electronic records or physical records relating to Rights Certificates cancelled or destroyed by the Rights Agent.

Section 9. Reservation and Availability of Capital Stock. The Company covenants and agrees that, from and
after the Distribution Date, it will cause to be reserved and kept available out of its authorized and unissued Common Stock (and, following the occurrence of a Trigger Event, out of its authorized and unissued Common Stock and/or other securities
or out of its shares held in its treasury) the number of shares of Common Stock (and, following the occurrence of a Trigger Event, Common Stock and/or other securities) that will be sufficient to permit the exercise in full of all outstanding
Rights. 
 So long as the Common Stock (and, following the occurrence of a Trigger Event, Common Stock and/or
other securities) issuable upon the exercise of Rights may be listed on the New York Stock Exchange (“NYSE”) or any other national securities exchange or traded in the over-the-counter market, 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 NYSE or such other exchange or market upon official notice of issuance upon such exercise.

  
 11 

 The Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Common Stock (and, following the occurrence of a Trigger Event, Common Stock and/or other securities) delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to
payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable shares. 
 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 Common Stock upon the exercise of Rights, to register and
qualify such Common Stock 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 Expiration Date. The Company may temporarily
suspend, from time to time for a period of time not to exceed one hundred twenty (120) days in any particular instance, the exercisability of the Rights in order to prepare and file a registration statement under the Securities Act and permit
it to become effective or in order to prepare and file any supplement or amendment to such registration statement that the Board determines to be necessary and appropriate under applicable law. Upon any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. Notwithstanding any provision of this Plan to the contrary, the
Rights shall not be exercisable in any jurisdiction unless the requisite qualification or exemption in such jurisdiction shall have been obtained and until a registration statement under the Securities Act (if required) shall have been declared
effective. 
 The Company further covenants and agrees that it will pay when due and payable any and all taxes
and charges which may be payable in respect of the issuance or delivery of the Right Certificates or of any Common Stock (and/or other securities, as the case may be) upon the exercise of Rights. The Company shall not, however, be required to pay
any tax or charge which may be payable in respect of any transfer or delivery of Right Certificates to a Person other than, or the issuance or delivery of certificates for the Common Stock (and/or other securities, as the case may be) 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 for Common Stock (and/or other securities, as the case may be) in a name other than that of the
registered holder upon the exercise of any Rights until any such tax or charge shall have been paid (any such tax or charge being payable by the registered holder of such Right Certificate at the time of surrender) or until it has been established
to the Company’s satisfaction that no such tax or charge is due. 
 Section 10. Common Stock Record
Date. Each Person in whose name any certificate for Common Stock (and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Stock (and/or
other securities, as the case may be) represented thereby on, and such certificate shall be dated, the date upon which the Right Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and any applicable taxes or
charges) was duly made; provided, however, that if the date of such surrender and payment is a date upon which the Common Stock (and/or other securities, as the case may be) transfer books of the

  
 12 

 
Company are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the Common Stock
(and/or other securities, as the case may be) transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby (or an exchange pursuant to Section 27), the holder of a Right Certificate shall not be entitled
to any rights of a holder of Common Stock (or other securities, as the case may be) 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. 
 Section 11.
Adjustment of Purchase Price, Number of Shares or Number of Rights. The Purchase Price, the number of shares of Common 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. 
 11.1. Post-Execution
Events. 
 11.1.1. Corporate Dividends, Reclassifications, Etc. In the event the Company shall, at
any time after the date of this Plan, (A) declare and pay a dividend on the Common Stock payable in Common Stock, (B) subdivide the outstanding Common Stock, (C) combine the outstanding Common Stock into a smaller number of shares of
Common Stock or (D) issue any shares of its capital stock in a reclassification of the Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving
corporation), except as otherwise provided in this Section 11.1.1, 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 Common Stock transfer books of the Company were open, such holder would have owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination or reclassification; provided, however, that in no event shall the consideration to be paid upon the exercise of 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 Section 11.1.1 and Section 11.1.2, the adjustment provided for in this Section 11.1.1 shall be in addition to,
and shall be made prior to, the adjustment required pursuant to, Section 11.1.2. 
 11.1.2. Acquiring Person Events; Triggering Events. Subject to Section 27, in the event that a Trigger Event occurs, then, from and after the close of business on the tenth (10th) business day after the first occurrence of such event (or such
later date as the Board may select), each holder of a Right, except as provided below, shall thereafter have a right to receive, upon exercise thereof at a price per Right equal to the product of ten (10) times the then-current Purchase Price
multiplied by the number of one tenths of a share of Common Stock for which a Right is then exercisable (without giving effect to this Section 11.1.2), in accordance with the terms of this Plan, such number of whole shares of Common
Stock as shall equal the result obtained by (x) multiplying the product of ten (10) times the then-current Purchase Price by the 

  
 13 

 
number of one tenths of a share of Common Stock for which a Right is then exercisable (without giving effect to this Section 11.1.2) and (y) dividing that product by 50% of the
then-current per share market price of the Common Stock (determined pursuant to Section 11.4) on the earlier of the date of the occurrence of or the date of the first public announcement of a Trigger Event (such number of whole shares of
Common Stock, the “Adjustment Shares”); provided that the Purchase Price and the number of Adjustment Shares shall thereafter be subject to further adjustment as appropriate in accordance with Section 11.6.
Notwithstanding the foregoing, upon and after the occurrence of a Trigger Event, any Rights that are or were acquired or Beneficially Owned by (1) any Acquiring Person or any Affiliate or Associate of an Acquiring Person, (2) a transferee
of any Acquiring Person (or any Affiliate or Associate of an Acquiring Person) who becomes a transferee after the Acquiring Person becomes such, or (3) a transferee of any Acquiring Person (or any Affiliate or Associate of an Acquiring Person)
who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in
such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board has determined is part of a plan, arrangement or
understanding which has as a primary purpose or effect avoidance of this Section 11.1.2, and subsequent transferees, shall become void without any further action, and any holder (whether or not such holder is an Acquiring Person or an
Affiliate or Associate of an Acquiring Person) of such Rights shall thereafter have no right to exercise such Rights under any provision of this Plan or otherwise. From and after the Trigger Event, no Right Certificate shall be issued pursuant to
Section 3 or Section 6 that represents Rights that are or have become void pursuant to the provisions of this paragraph, and any Right Certificate delivered to the Rights Agent that represents Rights that are or have become
void pursuant to the provisions of this paragraph shall be canceled. 
 The Company shall use all reasonable
efforts to ensure that the provisions of this Section 11.1.2 are complied with, but shall have no liability to any holder of Right Certificates or any other Person as a result of its failure to make any determinations with respect to any
Acquiring Person or any Affiliate or Associate of an Acquiring Person or transferees hereunder. 
 From and
after the occurrence of an event specified in Section 13.1, any Rights that theretofore have not been exercised pursuant to this Section 11.1.2 shall thereafter be exercisable only in accordance with Section 13
and not pursuant to this Section 11.1.2. 
 11.1.3. Insufficient Shares. In the event that
upon the occurrence of a Trigger Event there shall not be sufficient Common Stock authorized but unissued, or held by the Company as treasury shares, to permit the exercise in full of the Rights in accordance with the foregoing
Section 11.1.2, the Company shall take all such action as may be necessary to authorize additional Common Stock for issuance upon exercise of the Rights, provided, however, that if the Company determines that it is unable to cause
the authorization of a sufficient number of additional shares of Common Stock, then, in the event the Rights become exercisable, the Company, with respect to each Right and to the extent necessary and permitted by applicable law and any agreements
or instruments in effect on the date hereof to which it is a party, shall: (A) determine the excess of (1) the value of the Adjustment Shares issuable upon the exercise of a Right (the “Current Value”), over (2) the
product of ten (10) times the Purchase Price (such 

  
 14 

 
excess, the “Spread”) and (B) with respect to each Right (other than Rights which have become null and void pursuant to Section 11.1.2), make adequate provision
to substitute for the Adjustment Shares, upon payment of the product of ten (10) times 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 fractions of shares, of preferred stock which, by virtue of having dividend, voting and liquidation rights substantially comparable to those of the Common Stock, the Board has deemed in good faith to have substantially the
same value as the Common Stock) (each such share of preferred stock or fractions of shares of preferred stock constituting a “common stock equivalent”)), (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, where such aggregate value has been determined by the Board based upon the advice of a nationally recognized investment banking firm selected in good faith by the
Board; provided, however, that if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the occurrence of a Trigger Event, then the Company shall be
obligated to deliver, to the extent necessary and permitted by applicable law and any agreements or instruments in effect on the date hereof to which it is a party, upon the surrender for exercise of a Right and without requiring payment of the
product of ten (10) times the Purchase Price, Common Stock (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If, upon the occurrence of a Trigger Event, the Board shall
determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, then, if the Board so elects, the thirty (30) day period set forth above may be
extended to the extent necessary, but not more than one hundred twenty (120) days following the occurrence of a Trigger Event, in order that the Company may seek stockholder approval for the authorization of such additional shares (such thirty
(30) day period, as it may be extended, is herein called the “Substitution Period”). To the extent that the Company determines that some actions need be taken pursuant to the first and/or second sentences of this
Section 11.1.3, the Company (x) shall provide that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to
seek any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily suspended as well as a public announcement at such time as the suspension is no longer in effect. For purposes of this Section 11.1.3, the value of a share
of Common Stock shall be the then-current per share market price (as determined pursuant to Section 11.4) on the date of the occurrence of a Trigger Event and the value of any “common stock equivalent” shall be deemed to have
the same value as the Common Stock on such date. The Board may, but shall not be required to, establish procedures to allocate the right to receive Common Stock upon the exercise of the Rights among holders of Rights pursuant to this
Section 11.1.3. 
 11.2. Dilutive Rights Offering. In case the Company shall fix a record
date for the issuance of rights, options or warrants to all holders of Common Stock entitling them (for a period expiring within forty-five (45) calendar days after such record date) to subscribe for or purchase Common Stock (or common stock
equivalents) or securities convertible into Common Stock or common stock equivalents at a price per share of Common Stock or per share of common stock equivalents (or having a conversion or exercise price per share, if a security

  
 15 

 
convertible into or exercisable for Common Stock or common stock equivalents) less than the then-current per share market price of the Common Stock (as determined pursuant to
Section 11.4) on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which
shall be the number of shares of Common Stock and common stock equivalents outstanding on such record date plus the number of shares of Common Stock and common stock equivalents which the aggregate offering price of the total number of shares of
Common Stock and/or common stock equivalents to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current per share market price and the denominator of which shall be the
number of shares of Common Stock and shares of common stock equivalents outstanding on such record date plus the number of additional shares of Common Stock and/or common stock equivalents 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, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Common Stock and common stock equivalents owned by or held for the account of the
Company or any Subsidiary of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such rights or warrants are not
so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed. 
 11.3. Distributions. In case the Company shall fix a record date for the making of a distribution to all holders of the Common 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, cash, securities or assets (other than regular periodic cash dividends out of the earnings or retained earnings of the Company) or
convertible securities, or subscription rights or warrants (excluding those referred to in Section 11.2), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which shall be the then-current per share market price of the Common Stock (as determined pursuant to Section 11.4) on such record date, less the fair market value (as
determined in good faith by the Board, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent) of the portion of the cash, assets, securities or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to one share of Common Stock and the denominator of which shall be such then-current per share market price of the Common Stock (as determined pursuant to Section 11.4);
provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company to be issued upon exercise of one Right. Such adjustments
shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the Purchase Price shall again be adjusted to be the Purchase Price that would then be in effect if such record date had not
been fixed. 

  
 16 

 11.4. Current Per Share Market Value. 

11.4.1. General. For the purpose of any computation hereunder, the “current per share market
price” of any security (a “Security” for the purpose of this Section 11.4.1) on any date shall be deemed to be the average of the daily closing prices per share of such Security for the thirty
(30) consecutive Trading Days (as such term is hereinafter defined) immediately prior to, but not including, such date; provided, however, that in the event that the then-current per share market price of the Security is determined
during any period following the announcement by the issuer of such Security of (i) a dividend or distribution on such Security payable in shares of such Security or securities convertible into such shares or (ii) any subdivision,
combination or reclassification of such Security, and prior to the expiration of thirty (30) Trading Days after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification,
then, and in each such case, the “current per share market price” shall be appropriately adjusted to reflect the then-current market price per share equivalent of such Security. The closing price for each day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or
admitted to trading on the NYSE or, if the Security is not listed or admitted to trading on the NYSE, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities
exchange on which the Security is listed or admitted to trading or, if the Security is not listed or admitted to trading on any national securities exchange, the last quoted price or, if on such date the Security is not so quoted, the average of the
high bid and low asked prices in the over-the-counter market, as reported thereby or such other system then in use, or, if on any such date the Security is not quoted by any such organization, the average of the closing bid and asked prices as
furnished by a professional market maker making a market in the Security selected by the Board. If on any such date no such market maker is making a market in the Security, the fair value of the Security 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 Security is listed or admitted to trading is open for the transaction of business or, if the Security
is not listed or admitted to trading on any national securities exchange, a Business Day. If the Security is not publicly held or not so listed or traded, or if on any such date the Security is not so quoted and no such market maker is making a
market in the Security, “current per share market price” shall mean the fair value per share as determined in good faith by the Board or, if at the time of such determination there is an Acquiring Person, by a nationally recognized
investment banking firm selected by the Board, which shall have the duty to make such determination in a reasonable and objective manner, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for
all purposes. 
 11.5. Insignificant Changes. 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. Any adjustments which by reason of this Section 11.5 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 thousandth of a share of Common Stock or other share or security, as the case may be. 

  
 17 

 11.6. Shares Other Than Common Stock. If as a result of an adjustment
made pursuant to Section 11.1, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than Common Stock, thereafter the number of such other shares so receivable
upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock contained in Sections 11.1, 11.2, 11.3, 11.5, 11.8,
11.9 and 11.13, and the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Common Stock shall apply on like terms to any such other shares. 

11.7. Rights Issued Subsequent to Adjustment. 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 tenths of a share of Common Stock and shares of other capital stock or other securities, assets or cash of the
Company, if any, purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein. 
 11.8. Effect of Adjustments on Existing Rights. Unless the Company shall have exercised its election as provided in Section 11.9, upon each adjustment of the Purchase Price as a result
of the calculations made in Sections 11.2 and 11.3, each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one tenths of
a share of Common Stock (calculated to the nearest thousandth of a share of Common Stock) obtained by (i) multiplying (x) the number of one tenths of a share of Common Stock covered by a Right immediately prior to this adjustment by
(y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price. 

11.9. Adjustment in Number of Rights. 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 tenths of a share of Common Stock issuable 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 tenths of a share of Common Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of
Rights (calculated to the nearest 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 ten (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 11.9, 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, 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 

  
 18 

 
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 may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Right Certificates
on the record date specified in the public announcement. 
 11.10. Right Certificates Unchanged.
Irrespective of any adjustment or change in the Purchase Price or the number of one tenths of a share of Common Stock issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the
Purchase Price per one tenth of a share and the number of one tenths of a share of Common Stock which were expressed in the initial Right Certificates issued hereunder. 

11.11. Par Value Limitations. Before taking any action that would cause an adjustment reducing the Purchase Price
per whole share of Common Stock (or other capital stock) below the then par value, if any, of the Common 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 Common Stock or other such shares at such adjusted Purchase Price. 

11.12. Deferred Issuance. In any case in which this Section 11 shall require that an adjustment in the
Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date of that number of shares of Common
Stock and shares of other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Common Stock and shares of other capital stock or other securities, assets or cash 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. 
 11.13. Reduction in
Purchase Price. 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 Common Stock, issuance wholly for cash of any of the Common Stock at less than the
then-current market price, issuance wholly for cash of Common Stock or securities which by their terms are convertible into or exchangeable for Common Stock, dividends on Common Stock payable in Common Stock or issuance of rights, options or
warrants referred to hereinabove in this Section 11, hereafter made by the Company to holders of its Common Stock shall not be taxable to such stockholders. 

11.14. Company Not to Diminish Benefits of Rights. The Company covenants and agrees that after the earlier of the
Stock Acquisition Date or Distribution Date it will not, except as permitted by Section 23, Section 26 or Section 27, 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 substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights. 

  
 19 

 11.15. Adjustment of Rights Associated with Common Stock.
Notwithstanding anything contained in this Plan to the contrary, in the event that the Company shall at any time after the date hereof and prior to the Distribution Date (i) declare or pay any dividend on the outstanding Common Stock payable in
shares of Common Stock, (ii) effect a subdivision or consolidation of the outstanding Common Stock (by reclassification or otherwise than by the payment of dividends payable in shares of Common Stock), or (iii) combine the outstanding
Common Stock into a greater or lesser number of shares 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 but prior to the Distribution Date or
in accordance with Section 22 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. The adjustments provided for in this Section 11.15 shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation is effected. 

Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as
provided in Sections 11 or 13, the Company shall (a) promptly prepare a certificate setting forth such adjustment, and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Rights Agent and
with each transfer agent for the Common Stock a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate (or, if before the Distribution Date, to each holder of a certificate representing shares of
Common Stock or Book Entry Shares in respect thereof) in accordance with Section 25. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment or statement 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. Consolidation, Merger or Sale or Transfer of Assets or Earning Power. 

13.1. Certain Transactions. In the event that, from and after the first occurrence of a Trigger Event, directly or
indirectly, (A) the Company shall consolidate with, or merge with and into, any other Person and the Company shall not be the continuing or surviving corporation, (B) any Person shall consolidate with the Company, or merge with and into
the Company and the Company shall be the continuing or surviving corporation of such merger and, in connection with such merger, all or part of the Common Stock shall be changed into or exchanged for stock or other securities of the Company or any
other Person or cash or any other property, or (C) the Company shall sell, exchange, mortgage or otherwise transfer (or one or more of its Subsidiaries shall sell, exchange, mortgage or otherwise transfer), in one or more transactions, assets
or earning power aggregating 50% or more of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company or one or 

  
 20 

 
more wholly-owned Subsidiaries of the Company in one or more transactions each of which complies with Section 11.14), then, and in each such case, proper provision shall be made so
that (i) each holder of a Right (other than Rights which have become null and void pursuant to Section 11.1.2) shall thereafter have the right to receive, upon the exercise thereof at a price per Right equal to the product of ten
(10) times the then-current Purchase Price multiplied by the number of one tenths of a share of Common Stock for which a Right was exercisable immediately prior to the first occurrence of a Trigger Event (as subsequently adjusted pursuant to
Sections 11.1.1, 11.2, 11.3, 11.8, 11.9 and 11.12), in accordance with the terms of this Plan and in lieu of Common Stock, such number of validly authorized and issued, fully paid, non-assessable and freely tradable shares of Common
Stock of the Principal Party (as such term is hereinafter defined) not subject to any liens, encumbrances, rights of first refusal or other adverse claims, as shall be equal to the result obtained by (x) multiplying the product of ten
(10) times the then-current Purchase Price by the number of one tenths of a share of Common Stock for which a Right was exercisable immediately prior to the first occurrence of a Trigger Event (as subsequently adjusted pursuant to Sections
11.1.1, 11.2, 11.3, 11.8, 11.9 and 11.12) and (y) dividing that product by 50% of the then-current per share market price of the Common Stock of such Principal Party (determined pursuant to Section 11.4) on the date of
consummation of such consolidation, merger, sale or transfer; provided that the price per Right so payable and the number of shares of Common Stock of such Principal Party so receivable upon exercise of a Right shall thereafter be subject to
further adjustment as appropriate in accordance with Section 11.6 to reflect any events covered thereby occurring in respect of the Common Stock of such Principal Party after the occurrence of such consolidation, merger, sale or
transfer; (ii) such Principal Party shall thereafter be liable for, and shall assume, by virtue of such consolidation, merger, sale or transfer, all of the obligations and duties of the Company pursuant to this Plan; (iii) the term
“Company” shall thereafter be deemed to refer to such Principal Party; and (iv) such Principal Party shall take such steps (including, but not limited to, the reservation of a sufficient number of shares of its Common Stock in
accordance with Section 9) in connection with such consummation as may be necessary to assure that the provisions hereof shall thereafter be applicable, as nearly as reasonably may be, in relation to its Common Stock thereafter
deliverable upon the exercise of the Rights; provided that, upon the subsequent occurrence of any consolidation, merger, sale or transfer of assets or other extraordinary transaction in respect of such Principal Party, each holder of a Right
shall thereupon be entitled to receive, upon exercise of a Right and payment of the Purchase Price as provided in this Section 13.1, such cash, shares, rights, warrants and other property which such holder would have been entitled to
receive had such holder, at the time of such transaction, owned the Common Stock of the Principal Party receivable upon the exercise of a Right pursuant to this Section 13.1, and such Principal Party shall take such steps (including, but
not limited to, reservation of shares of stock) as may be necessary to permit the subsequent exercise of the Rights in accordance with the terms hereof for such cash, shares, rights, warrants and other property. The Company shall not consummate any
such consolidation, merger, sale or transfer unless prior thereto the Company and such Principal Party shall have executed and delivered to the Rights Agent a supplemental agreement confirming that the requirements of this Section 13.1
and Section 13.2 shall promptly be performed in accordance with their terms and that such consolidation, merger, sale or transfer of assets shall not result in a default by the Principal Party under this Plan as the same shall have been
assumed by the Principal Party pursuant to this Section 13.1 and Section 13.2 and providing that, as soon as practicable after executing such agreement pursuant to this Section 13, the Principal Party, at its own
expense, shall: 
  

  
 21 

 (1) prepare and file a registration statement under the Securities Act, if
necessary, with respect to the Rights and the securities purchasable upon exercise of the Rights on an appropriate form, use its best efforts to cause such registration statement to become effective as soon as practicable after such filing and use
its best efforts to cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Expiration Date and similarly comply with applicable state securities laws;

 (2) use its best efforts, if the Common Stock of the Principal Party shall be listed or admitted to trading
on the NYSE or on another national securities exchange, to list or admit to trading (or continue the listing of) the Rights and the securities purchasable upon exercise of the Rights on the NYSE or such securities exchange; 

(3) deliver to holders of the Rights historical financial statements for the Principal Party which comply in all respects
with the requirements for registration on Form 10 (or any successor form) under the Exchange Act; and 
 (4)
obtain waivers of any rights of first refusal or preemptive rights in respect of the Common Stock of the Principal Party subject to purchase upon exercise of outstanding Rights. 

In case the Principal Party has a provision in any of its authorized securities or in its articles or certificate of
incorporation or by-laws or other instrument governing its corporate affairs, which provision would have the effect of (i) causing such Principal Party to issue (other than to holders of Rights pursuant to this Section 13), in
connection with, or as a consequence of, the consummation of a transaction referred to in this Section 13, Common Stock or common stock equivalents of such Principal Party at less than the then-current market price per share thereof
(determined pursuant to Section 11.4) or securities exercisable for, or convertible into, Common Stock or common stock equivalents of such Principal Party at less than such then-current market price (other than to holders of Rights
pursuant to this Section 13), or (ii) providing for any special payment, taxes, charges or similar provision in connection with the issuance of the Common Stock of such Principal Party pursuant to the provision of
Section 13, then, in such event, the Company hereby agrees with each holder of Rights that it shall not consummate any such transaction unless prior thereto the Company and such Principal Party shall have executed and delivered to the
Rights Agent a supplemental agreement providing that the provision in question of such Principal Party shall have been canceled, waived or amended, or that the authorized securities shall be redeemed, so that the applicable provision will have no
effect in connection with, or as a consequence of, the consummation of the proposed transaction. 
 The Company
covenants and agrees that it shall not, at any time after the Trigger Event, enter into any transaction of the type described in clauses (A) through (C) of this Section 13.1 if (i) at the time of or immediately after
such consolidation, merger, sale, transfer or other transaction there are any rights, warrants or other instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits

  
 22 

 
intended to be afforded by the Rights, (ii) prior to, simultaneously with or immediately after such consolidation, merger, sale, transfer or other transaction, the stockholders of the Person
who constitutes, or would constitute, the Principal Party for purposes of Section 13.2 shall have received a distribution of Rights previously owned by such Person or any of its Affiliates or Associates or (iii) the form or nature
of organization of the Principal Party would preclude or limit the exercisability of the Rights. The provisions of this Section 13 shall similarly apply to successive transactions of the type described in clauses (A) through
(C) of this Section 13.1. 
 13.2. Principal Party. “Principal Party” shall mean:

 (i) in the case of any transaction described in clauses (A) or (B) of the first sentence of
Section 13.1: (i) the Person that is the issuer of the securities into which the Common Stock is converted in such merger or consolidation, or, if there is more than one such issuer, the issuer the Common Stock of which has the
greatest aggregate market value of shares outstanding, or (ii) if no securities are so issued, (x) the Person that is the other party to the merger, if such Person survives said merger, or, if there is more than one such Person, the Person
the Common Stock of which has the greatest aggregate market value of shares outstanding or (y) if the Person that is the other party to the merger does not survive the merger, the Person that does survive the merger (including the Company if it
survives) or (z) the Person resulting from the consolidation; and 
 (ii) in the case of any transaction
described in clause (C) of the first sentence in Section 13.1, the Person that is the party receiving the greatest portion of the assets or earning power transferred pursuant to such transaction or transactions, or, if each Person
that is a party to such transaction or transactions receives the same portion of the assets or earning power so transferred or if the Person receiving the greatest portion of the assets or earning power cannot be determined, whichever of such
Persons is the issuer of Common Stock having the greatest aggregate market value of shares outstanding; provided, however, that in any such case described in the foregoing clause (i) or (ii) of this Section 13.2, if the
shares of Common Stock of such Person are not at such time or have not been continuously over the preceding twelve (12) month period registered under Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the shares of Common Stock of which are and have been so registered, the term “Principal Party” shall refer to such other Person, or (2) if such Person is a Subsidiary, directly or indirectly, of more than
one Person, the shares of Common Stock of all of which are and have been so registered, the term “Principal Party” shall refer to whichever of such Persons is the issuer of Common Stock having the greatest aggregate market value of shares
outstanding, or (3) if such Person is owned, directly or indirectly, by a joint venture formed by two or more Persons that are not owned, directly or indirectly, by the same Person, the rules set forth in clauses (1) and (2) above
shall apply to each of the owners having an interest in the venture as if the Person owned by the joint venture was a Subsidiary of both or all of such joint venturers, and the Principal Party in each such case shall bear the obligations set forth
in this Section 13 in the same ratio as its interest in such Person bears to the total of such interests. 
 13.3. Approved Acquisitions. Notwithstanding anything contained herein to the contrary, upon the consummation of any merger or other acquisition transaction of the type described in clause (A),
(B) or (C) of Section 13.1 involving the Company pursuant to a merger or other acquisition agreement between the Company and any Person (or one or more of such Person’s Affiliates or Associates), which agreement has been
approved by the Board prior to any Person becoming an Acquiring Person, this Plan and the rights of holders of Rights hereunder shall be terminated in accordance with Section 7.1. 

  
 23 

 Section 14. Fractional Rights and Fractional Shares. 

14.1. Cash in Lieu of Fractional Rights. 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 11.15). 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 then-current market value of a whole Right. For the purposes of this Section 14.1, the then-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 NYSE or, if the Rights are not listed or admitted to trading on the NYSE, 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 the NYSE or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Rights selected by the Board. If on any such date no such market maker is making a market in the Rights, the then-current market value of the Rights on such date shall be the fair value of the Rights as determined
in good faith by the Board, or, if at the time of such determination there is an Acquiring Person, by a nationally recognized investment banking firm selected by the Board, which shall have the duty to make such determination in a reasonable and
objective manner, which determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes. 
 14.2. Cash in Lieu of Fractional Shares of Common Stock. The Company shall not be required to issue fractions of shares of Common Stock upon exercise of the Rights (notwithstanding the fact that
any individual Right may only be exercisable for a fraction of a share 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 (as
determined in accordance with Section 14.1) for the Trading Day immediately prior to the date of such exercise or exchange. For all purposes under this Plan, the Company shall aggregate the Rights held by each record holder of Right
Certificates (and the number of shares of Common Stock represented by such Rights) in determining whether and to what extent such record holder would otherwise be entitled to receive fractional shares of Common Stock. 

  
 24 

 14.3. Waiver of Right to Receive Fractional Rights or Shares. The
holder of a Right by the acceptance of the Rights expressly waives his right to receive any fractional Rights or any fractional shares upon exercise or exchange of a Right, except as permitted by this Section 14. 

Section 15. Rights of Action. All rights of action in respect of this Plan, except the rights of action given
to the Rights Agent under Section 18, 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), may, in his own behalf and for
his own benefit, enforce this Plan, and may institute and maintain any suit, action or proceeding against the Company to enforce this Plan, or otherwise enforce or 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 Plan. 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 Plan and shall be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of, the obligations
of any Person (including, without limitation, the Company) subject to this Plan. 
 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 not be evidenced by a Right Certificate and will be
transferable only in connection with the transfer of the Common Stock; 
 (b) as of and after the
Distribution Date, the Right Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer
with all required certifications completed; and 
 (c) the Company and the Rights Agent may deem
and treat the Person in whose name the Right Certificate (or, prior to the Distribution Date, the associated Common Stock certificate or Book Entry Share) 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 Book Entry Share made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the
Company nor the Rights Agent shall be affected by any notice to the contrary. 
 Section 17. 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 Common 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 

  
 25 

 
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
Section 24), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Right Certificate shall have been exercised in accordance with the provisions hereof. 

Section 18. Concerning the Rights Agent. 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 Plan and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without
gross negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Plan, including the costs and expenses of defending
against any claim of liability arising therefrom, directly or indirectly. 
 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 Plan in reliance upon any Right Certificate or certificate for the 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. 
 Section 19. Merger
or Consolidation or Change of Name of Rights Agent. Any corporation or limited liability company or other entity into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any corporation or
limited liability company or other entity resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation or limited liability company 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 Plan 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 or limited liability company or other entity would be eligible for appointment as a successor Rights Agent under the provisions of Section 21. In case at the time such successor Rights Agent shall succeed to the
agency created by this Plan, 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 Plan. 

  
 26 

 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 Plan. 
 Section 20. Duties of Rights Agent. The Rights Agent undertakes
the duties and obligations imposed by this Plan 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: 

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

20.2. Certificates as to Facts or Matters. Whenever in the performance of its duties under this Plan 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 Chief Executive Officer, the President, any Executive Vice President or any such other officers of the Company as any of them may designate
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 Plan in reliance upon such certificate. 

20.3. Standard of Care. The Rights Agent shall be liable hereunder only for its own gross negligence, bad faith or
willful misconduct. 
 20.4. Reliance on Plan and Right Certificates. The Rights Agent shall not be
liable for or by reason of any of the statements of fact or recitals contained in this Plan or in the Right Certificates (except as to 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. 
 20.5. No Responsibility as to Certain Matters.
The Rights Agent shall not be under any responsibility in respect of the validity of this Plan or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any 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 Plan 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 11.1.2) or any adjustment required under the provisions of Sections 3, 11, 13, 23 or 27 or responsible for the manner, method or amount of
any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after actual notice of any such change or adjustment); nor shall
it by any act 

  
 27 

 
hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Common Stock or other securities to be issued pursuant to this Plan or any Right
Certificate or as to whether any Common Stock will, when so issued, be validly authorized and issued, fully paid and nonassessable. 
 20.6. Further Assurance by Company. 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 Plan. 

20.7. Authorized Company Officers. The Rights Agent is hereby authorized and directed to accept instructions with
respect to the performance of its duties hereunder from any one of the Chief Executive Officer, the President, any Executive Vice President and/or any such other officers of the Company as any of them may designate, and to apply to such officers for
advice or instructions in connection with its duties under this Plan, and it shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer or for any delay in acting while
waiting for these 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 with respect to
its duties or obligations under this Plan 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 to the Company 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 therein (which date shall not be less than three (3) Business Days after the date any such officer actually receives such application, unless
any such officer shall have consented in writing to an earlier date) unless, prior to taking of any such action (or the effective date in the case of omission), the Rights Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted. 
 20.8. Freedom to Trade in Company
Securities. 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 Plan. Nothing herein shall preclude the Rights Agent from acting in any other capacity for
the Company or for any other legal entity. 
 20.9. Reliance on Attorneys and Agents. 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, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, omission, default, neglect or misconduct, provided that reasonable care was exercised in the selection and continued
employment thereof. 

  
 28 

 20.10. Incomplete Certificate. 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 of an Acquiring Person), the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Company. 

20.11. Rights Holders List. 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 Rights. 

Section 21. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and be
discharged from its duties under this Plan upon thirty (30) days’ notice in writing mailed to the Company and to each transfer agent of the Common Stock by registered or certified mail. Following the Distribution Date, the Company shall
promptly notify the holders of the Right Certificates by first-class mail of any such resignation. The Company may remove the Rights Agent or any successor Rights Agent upon thirty (30) days’ notice in writing, mailed to the Rights Agent
or successor Rights Agent, as the case may be, and to each transfer agent of the Common Stock by registered or certified mail, and 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 thirty (30) days after giving notice of
such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a 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 a Person organized and doing business under the laws of the State of New York or the State of Delaware (or any other state of the United States so long as such Person is authorized to do business as a banking institution in the State of New York
or the State of Delaware) in good standing, having an office in the State of New York or the State of Delaware, which is authorized under such laws to exercise stock transfer or corporate trust powers and is subject to supervision or examination by
Federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $100 million. 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

  
 29 

 
and each transfer agent of the Common 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
Plan 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 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 Plan. In addition, in connection with the issuance or sale of Common Stock following the Distribution Date and
prior to the Expiration Date, the Company shall, with respect to Common Stock so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement, granted or awarded, or upon exercise, conversion or exchange of
securities heretofore or hereinafter issued by the Company, in each case existing prior to the Distribution Date, 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. 
 23.1. Right to Redeem. The Board may, at its option, at any time prior to a Trigger Event, redeem all but not less than all of the then outstanding Rights at a redemption price of $0.0001 per
Right, appropriately adjusted to reflect any stock split, stock dividend, recapitalization or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the “Redemption Price”), and
the Company may, at its option, pay the Redemption Price in Common Stock (based on the “current per share market price,” determined pursuant to Section 11.4, of the Common Stock at the time of redemption), cash or any other
form of consideration deemed appropriate by the Board. The redemption of the Rights by the Board may be made effective at such time, on such basis and subject to such conditions as the Board in its sole discretion may establish. 

23.2. Redemption Procedures. Immediately upon the action of the Board ordering the redemption of the Rights (or at
such later time as the Board may establish for the effectiveness of such redemption), and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall
be to receive the Redemption Price for each Right so held. The Company shall promptly give public notice of such redemption; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such
redemption. The Company shall promptly give, or cause the Rights Agent to give, notice of such redemption to the holders of the then outstanding Rights by mailing such notice to all such holders at their last addresses as they appear upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the 

  
 30 

 
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. The failure to give notice required by this Section 23.2 or any defect therein shall not affect the validity of the action taken by
the Company. Neither the Company nor any of its Affiliates or Associates may redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this Section 23 or in
Section 27, and other than in connection with the purchase, acquisition or redemption of Common Stock prior to the Distribution Date. 
 Section 24. Notice of Certain Events. In case the Company shall propose at any time after the earlier of the Stock Acquisition Date and the Distribution Date (a) to pay any dividend
payable in stock of any class to the holders of Common Stock or to make any other distribution to the holders of Common Stock (other than regular periodic cash dividends out of earnings or retained earnings of the Company), or (b) to offer to
the holders of Common Stock rights or warrants to subscribe for or to purchase any additional Common Stock or shares of stock of any class or any other securities, rights or options, or (c) to effect any reclassification of its Common Stock
(other than a reclassification involving only the subdivision of outstanding Common Stock), or (d) to effect any consolidation or merger into or with, or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more of the assets or earning power of the Company and its Subsidiaries (taken as a whole) to, any other Person, or (e) to effect the liquidation, dissolution or winding
up of the Company, or (f) to declare or pay any dividend on the Common Stock payable in Common Stock or to effect a subdivision, combination or consolidation of the Common Stock (by reclassification or otherwise than by payment of dividends in
Common Stock), then, in each such case, the Company shall give to the Rights Agent and to each holder of a Right Certificate, in accordance with Section 25, 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 Common Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (a) or (b) above at least ten (10) days prior to the record date for determining holders
of the Common Stock for purposes of such action, and in the case of any such other action, at least ten (10) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Common Stock,
whichever shall be the earlier. 
 In case any event set forth in Section 11.1.2 or
Section 13 shall occur, then, in any such case, (i) the Company shall as soon as practicable thereafter give to the Rights Agent and to each holder of a Right Certificate, in accordance with Section 25, a notice of the
occurrence of such event, which notice shall describe the event and the consequences of the event to holders of Rights under Section 11.1.2 and Section 13, and (ii) all references in this Section 24 to Common
Stock shall be deemed thereafter to also refer to other securities, if appropriate.

 Notices or demands authorized by this Plan to be given or made by the Company or the Rights Agent to the holder of any Right Certificate (or, prior to the Distribution Date, to the holder of any
certificate representing Common Stock or of any Book Entry Shares) 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
or the transfer agent or registrar for the Common Stock; provided that prior to the Distribution Date a filing by the Company with the Securities and Exchange Commission shall constitute sufficient notice to the holders of securities of the
Company, including the Rights, for purposes of this Plan and no other notice need be given. 
 Section 26.
Supplements and Amendments. 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 Plan in any
respect without the approval of any holders of Rights or Common Stock. From and after the time that the Rights are no longer redeemable, the Company may, and the Rights Agent shall, if the Company so directs, from time to time supplement or amend
this Plan without the approval of any holders of Rights (i) to cure any ambiguity or to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein or (ii) to make any other
changes or provisions in regard to matters or questions arising hereunder which the Company may deem necessary or desirable, including but not limited to extending the Final Expiration Date; provided, however, that no such supplement or
amendment shall adversely affect the 

  
 32 

 
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 supplement or amendment may cause the Rights again to
become redeemable or cause this Plan again to become amendable as to an Acquiring Person or an Affiliate or Associate of an Acquiring Person, other than in accordance with this sentence; provided further, that the right of the Board to extend
the Distribution Date shall not require any amendment or supplement hereunder. 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 that does not amend Sections 18, 19, 20 or 21 hereof or this
Section 26 or any other Section of this Plan 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. The Company shall promptly provide
the Rights Agent with written notice of such supplement or amendment. 
 Section 27. Exchange. 

27.1. Exchange of Common Stock for Rights. The Board may, at its option, at any time after the occurrence of a
Trigger Event, exchange Common Stock for all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 11.1.2) by exchanging at an exchange ratio of
one share of Common Stock (or a lesser ratio as determined by the Board, if the Company does not have sufficient authorized and unreserved shares of Common Stock) per Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such amount per Right being hereinafter referred to as the “Exchange Consideration”). Notwithstanding the foregoing, the Board shall not be empowered to effect such exchange at
any time after any Acquiring Person shall have become the Beneficial Owner of 50% or more of the Common Stock then outstanding. From and after the occurrence of an event specified in Section 13.1, any Rights that theretofore have not
been exchanged pursuant to this Section 27.1 shall thereafter be exercisable only in accordance with Section 13 and may not be exchanged pursuant to this Section 27.1. The exchange of the Rights by the Board may
be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. Without limiting the foregoing, prior to effecting an exchange pursuant to this Section 27, the Board may direct
the Company to enter into a Trust Agreement in such form and with such terms as the Board shall then approve (the “Trust Agreement”). If the Board 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 Common Stock issuable pursuant to the exchange (or any portion thereof that has not theretofore been issued in connection with the exchange). From and after the time at which
such shares are issued to the Trust, all stockholders then 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. Any Common Stock issued at the direction of the Board in connection herewith shall be validly issued, fully paid
and nonassessable Common Stock, and the Company shall be deemed to have received as consideration for such issuance a benefit having a value that is at least equal to the aggregate par value of the shares so issued. 

  
 33 

 27.2. Exchange Procedures. Immediately upon the effectiveness of the
action of the Board ordering the exchange for any Rights pursuant to Section 27.1 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 the Exchange Consideration. The Company shall promptly give public notice of any such exchange; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such
exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange shall state the method by which the exchange of the Common Stock for Rights will be effected and, in the event of any partial exchange, the number of
Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than the Rights that have become null and void pursuant to the provisions of Section 11.1.2) held by each holder of
Rights. 
 27.3. Insufficient Shares. The Company may at its option substitute for each share of Common
Stock that would otherwise be issuable upon exchange of a Right, (i) cash, (ii) other equity securities of the Company or common stock equivalents, as such term is defined in Section 11.1.3), (iii) debt securities of the
Company, (iv) other assets or (v) any combination of the foregoing, in each case having an aggregate value equal to the current per share market price of one share of Common Stock (determined pursuant to Section 11.4) as of the
date of such exchange. Pursuant to Section 27.1, the Board may also determine a lesser ratio of shares of Common Stock per Right if the Company does not have sufficient authorized and unreserved shares of Common Stock to effect the
exchange at an exchange ratio of one share of Common Stock per Right. In the event that there shall not be sufficient shares of Common Stock issued but not outstanding or authorized but unissued and otherwise available for issuance to permit an
exchange of Rights for Common Stock as contemplated in accordance with this Section 27, the Company shall substitute to the extent of such insufficiency, for each share of Common Stock that would otherwise be issuable upon exchange of a
Right, consideration of any type described in Section 11.1.3(B)(1)-(6), which consideration shall have an aggregate current per share market price (determined pursuant to Section 11.4 hereof) equal to the current per share
market price of one share of Common Stock (determined pursuant to Section 11.4 hereof) as of the date of such exchange. 
 Section 28. Process to Seek Exemption Prior to Trigger Event. Any Person who desires to effect any acquisition of Common Stock that would, if consummated, result in such Person becoming an
Acquiring Person (a “Requesting Person”) may, prior to the Stock Acquisition Date, request that the Board grant an exemption with respect to such acquisition under this Plan so that such Person would be deemed to be an “Exempt
Person” under subsection (ii) of Section 1.8 hereof for purposes of this Plan, provided that such request is fully compliant and in accordance with this Section 28 (an “Exemption Request”).
An Exemption Request shall be in proper form and shall be delivered by overnight delivery service or first-class mail, postage prepaid, to the Secretary of the Company at the principal executive office of the Company. The Exemption Request shall be
deemed made upon actual receipt by the Secretary of the Company. To be in proper form, an Exemption Request shall set forth (i) the name and address of the Requesting Person, (ii) the number of shares of Common Stock then Beneficially
Owned by and the Percentage Stock Ownership of the Requesting Person, together with all Affiliates and 

  
 34 

 
Associates of the Requesting Person, and (iii) a reasonably detailed description of the transaction or transactions by which the Requesting Person would propose to become an Acquiring Person
and the maximum number and percentage of shares of Common Stock that the Requesting Person proposes to acquire. The Exemption Request shall be considered and evaluated by directors serving on the Board, or a duly constituted committee thereof, and
in the case of a duly constituted committee, the determination thereof shall be deemed to be the determination of the Board for purposes of such Exemption Request. The Board shall make a determination whether to grant an exemption in response to an
Exemption Request as promptly as practicable (and, in any event, within ten (10) Business Days) after receipt thereof; provided, that the failure of the Board to make a determination within such period shall be deemed to constitute the
denial by the Board of the Exemption Request. The Requesting Person shall respond promptly to reasonable and appropriate requests for additional information from the Board and its advisors to assist the Board in making its determination. For
purposes of considering the Exemption Request, any calculation of the number of shares of Common Stock outstanding at any particular time, including for purposes of determining the Percentage Stock Ownership of any Person, shall be made pursuant to
and in accordance with Section 382. The Board shall only grant an exemption in response to an Exemption Request if the Board determines in its sole discretion that the acquisition of Beneficial Ownership of Common Stock by the Requesting
Person, considered alone or with other transactions (including, without limitation, past transactions or contemplated transactions) (A) will not create a material risk that the Company’s (or any successor’s, or the Combined
Enterprise’s) Tax Benefits may be jeopardized or (B) is in the best interests of the Company or any successor or the Combined Enterprise despite the fact that it will create a material risk that the Company’s (or any successor’s
or the Combined Enterprise’s) Tax Benefits may be jeopardized. Any exemption granted hereunder may be granted in whole or in part, and may be subject to limitations or conditions (including a requirement that the Requesting Person agree that it
will not acquire Beneficial Ownership of shares of Common Stock in excess of the maximum number and percentage of shares approved by the Board), in each case as and to the extent the Board shall determine necessary or desirable to provide for the
protection of the Tax Benefits. Any Exemption Request may be submitted on a confidential basis and, except to the extent required by applicable law, the Company shall maintain the confidentiality of such Exemption Request and the Board’s
determination with respect thereto, unless the information contained in the Exemption Request or the Board’s determination with respect thereto otherwise becomes publicly available. 

Section 29. Waiver Subsequent to Stock Acquisition Date. The Board may, of its own accord or upon the request
of a stockholder (a “Waiver Request”), subsequent to a Stock Acquisition Date and prior to the Distribution Date, grant an exemption with respect to any Acquiring Person under this Plan so that such Acquiring Person would be deemed
to be an “Exempt Person” under subsection (ii) of Section 1.8 hereof for purposes of this Plan, provided that such request is fully compliant and in accordance with this Section 29. A Waiver Request
shall be in proper form and shall be delivered by overnight delivery service or first-class mail, postage prepaid, to the Secretary of the Company at the principal executive office of the Company. The Waiver Request shall be deemed made upon actual
receipt by the Secretary of the Company. To be in proper form, a Waiver Request shall set forth (i) the name and address of the Acquiring Person, (ii) the number of shares of Common Stock then Beneficially Owned by and the Percentage Stock
Ownership of the Acquiring Person, together with all Affiliates and Associates of the Acquiring Person, and (iii) a reasonably detailed description of the transaction 

  
 35 

 
or transactions by which the Acquiring Person became an Acquiring Person and the maximum number and percentage of shares of Common Stock that the Acquiring Person proposes to acquire. The facts
and circumstances with respect to the Trigger Event, including whether to grant an exemption, shall be considered and evaluated by directors serving on the Board, or a duly constituted committee thereof, and in the case of a duly constituted
committee, the determination thereof shall be deemed to be the determination of the Board for purposes of any exemption granted pursuant to this Section 29. The Board shall make a determination whether to grant an exemption in response
to a Waiver Request as promptly as practicable (and, in any event, within ten (10) Business Days) after receipt thereof; provided, that the failure of the Board to make a determination within such period shall be deemed to constitute the
denial by the Board of the Waiver Request. The Acquiring Person shall respond promptly to reasonable and appropriate requests for additional information from the Board and its advisors to assist the Board in making its determination. For purposes of
considering the Waiver Request, any calculation of the number of shares of Common Stock outstanding at any particular time, including for purposes of determining the Percentage Stock Ownership of any Person, shall be made pursuant to and in
accordance with Section 382. The Board shall only grant an exemption for an Acquiring Person if the Board determines in its sole discretion that the acquisition of Beneficial Ownership of Common Stock, considered alone or with other
transactions (including, without limitation, past transactions or contemplated transactions), would not create a material risk that the Company’s (or any successor’s or the Combined Enterprise’s) Tax Benefits may be jeopardized. Any
exemption granted hereunder may be granted in whole or in part, and may be subject to limitations or conditions (including a requirement that such Acquiring Person agree that it will not acquire Beneficial Ownership of shares of Common Stock in
excess of the maximum number and percentage of shares approved by the Board), in each case as and to the extent the Board shall determine necessary or desirable to provide for the protection of the Company’s or any successor’s or the
Combined Enterprise’s Tax Benefits. 
 Section 30. Successors. All the covenants and provisions
of this Plan by or for the benefit of the Company or the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder. 
 Section 31. Benefits of this Plan. Nothing in this Plan 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 Plan; but this Plan 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 32. Determination and
Actions by the Board or Committee Thereof. The Board, or a duly authorized committee thereof, shall have the exclusive power and authority to administer this Plan and to exercise the rights and powers specifically granted to the Board or to the
Company, or as may be necessary or advisable in the administration of this Plan, including, without limitation, the right and power to (i) interpret the provisions of this Plan and (ii) make all determinations deemed necessary or advisable
for the administration of this Plan (including, without limitation, a determination to redeem or not redeem the Rights or amend this Plan). In administering this Plan and exercising the rights and powers specifically granted to the Board and to the
Company hereunder, and in interpreting this Plan and making any 

  
 36 

 
determination hereunder, the Board, or a duly authorized committee thereof, may consider any and all facts, circumstances or information it deems to be necessary, useful or appropriate. All such
actions, calculations, interpretations and determinations that are done or made by the Board, or a duly authorized committee thereof, 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 to the fullest extent permitted by applicable law. In identifying any Acquiring Person, including the Percentage Stock Ownership of such Person, the Board is entitled to rely on the existence and absence of filings of
Schedule 13D or 13G under the Securities Exchange Act of 1934, as amended (or similar filings), as of any date, subject to its actual knowledge of the ownership of Company Securities. 

Section 33. Severability. If any term, provision, covenant or restriction of this Plan 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 Plan shall remain in full force and effect and shall in no way be affected, impaired or
invalidated. 
 Section 34. Governing Law. This Plan and each Right Certificate issued hereunder
shall be deemed to be a contract made under the internal 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 35. Counterparts. This Plan may be executed in any number of counterparts and
each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. A signature to this Plan transmitted electronically shall have the same authority,
effect and enforceability as an original signature. 
 Section 36. Descriptive Headings. Descriptive
headings of the several Sections of this Plan are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

 NOT EXERCISABLE AFTER FEBRUARY 13, 2014 OR AS OTHERWISE PROVIDED IN THE
TAX BENEFIT PRESERVATION PLAN (THE “PLAN”). THE RIGHTS ARE SUBJECT TO REDEMPTION AT $0.0001 PER RIGHT, AND TO EXCHANGE ON THE TERMS SET FORTH IN THE PLAN. UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SECTION 11.1.2 OF THE PLAN),
RIGHTS BENEFICIALLY OWNED BY OR TRANSFERRED TO AN ACQUIRING PERSON (AS DEFINED IN THE PLAN), OR ANY SUBSEQUENT HOLDER OF SUCH RIGHTS, WILL BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE. 

Right Certificate 

US AIRWAYS GROUP, INC. 
 This certifies that                     , or registered assigns, is the registered owner of the
number of Rights set forth above, each of which entitles the owner thereof, subject to the terms, provisions and conditions of the Tax Benefit Preservation Plan, dated as of February 13, 2013, as the same may be amended from time to time (the
“Plan”), between US Airways Group, Inc., a Delaware corporation (the “Company”), and American Stock Transfer & Trust Company, LLC, a New York limited liability trust company, as Rights Agent (the
“Rights Agent”), to purchase from the Company at any time after the Distribution Date and prior to 5:00 P.M. (New York time) on February 13, 2014, at the offices of the Rights Agent, or its successors as Rights Agent,
designated for such purpose, one tenth of a fully paid, nonassessable share of Common Stock, par value $0.01 per share (the “Common Stock”), of the Company, at a purchase price of $3.00 per one tenth of a share of Common Stock,
subject to adjustment (the “Purchase Price”), upon presentation and surrender of this Right Certificate with the Form of Election to Purchase and certification duly executed. The number of Rights evidenced by this Right Certificate
(and the number of one tenths of a share of Common Stock which may be purchased upon exercise thereof) set forth above, and the Purchase Price set forth above, are the number and Purchase Price as of February 13, 2013, based on the Common Stock
as constituted at such date. Capitalized terms used in this Right Certificate without definition shall have the meanings ascribed to them in the Plan. As provided in the Plan, the Purchase Price and the number of shares of Common Stock 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. 
 This Right Certificate is subject to all of the terms, provisions and conditions of the Plan, which terms, provisions and conditions are hereby incorporated herein by reference and made a part hereof and
to which Plan reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the Rights Agent, the Company and the holders of the Right Certificates. Copies of the Plan are on
file at the principal offices of the Company and the Rights Agent. 

  
 A- 1

 This Right Certificate, with or without other Right Certificates, upon
surrender at the offices of the Rights Agent designated for such purpose, may be exchanged for another Right Certificate or Right Certificates of like tenor and date evidencing Rights entitling the holder to purchase a like aggregate number of one
tenths of a share of Common Stock as the Rights evidenced by the Right Certificate or Right Certificates surrendered shall have entitled such holder to purchase. If this Right Certificate shall be exercised in part, the holder shall be entitled to
receive upon surrender hereof another Right Certificate or Right Certificates for the number of whole Rights not exercised. 
 Subject to the provisions of the Plan, the Board may, at its option, (i) redeem the Rights evidenced by this Right Certificate at a redemption price of $0.0001 per Right or (ii) exchange Common
Stock for the Rights evidenced by this Certificate, in whole or in part. 
 No fractional Common Stock will be
issued upon the exercise of any Right or Rights evidenced hereby, but in lieu thereof a cash payment will be made, as provided in the Plan. The number of shares of Common Stock to be issued upon the exercise of any Right or Rights evidenced hereby
shall be aggregated with the number of shares of Common Stock to be issued upon the exercise of any Right or Rights evidenced by any other Rights Certificates held by the holder hereof for purposes of determining whether and to what extent such
holder would otherwise be entitled to receive fractional shares of Common Stock hereunder. 
 No holder of this
Right Certificate, as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of the Common Stock or of any other securities of the Company which may at any time be issuable on the exercise hereof, nor shall
anything contained in the Plan or herein be construed to confer upon the holder hereof, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in the Plan), or to receive dividends or subscription rights, or otherwise, until
the Right or Rights evidenced by this Right Certificate shall have been exercised as provided in the Plan. 
 If
any term, provision, covenant or restriction of the Plan 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 the Plan shall
remain in full force and effect and shall in no way be affected, impaired or invalidated. 
 This Right
Certificate shall not be valid or binding for any purpose until it shall have been countersigned by the Rights Agent.

 EXHIBIT B 

As described in the Tax Benefit Preservation Plan, Rights which 

are held by or have been held by an Acquiring Person or any Affiliate or Associate of an Acquiring 

Person (as defined in the Tax Benefit Preservation Plan) and certain transferees thereof shall 

become null and void and will no longer be transferable. 
 SUMMARY OF RIGHTS TO PURCHASE 
 COMMON STOCK 

On February 13, 2013, and in connection with approving a certain Agreement and Plan of Merger (the “Merger
Agreement”), among AMR Corporation (“AMR”), AMR Merger Sub, Inc. and US Airways Group, Inc. (the “Company”), the Board of Directors of the Company declared a dividend of one common stock purchase right (a
“Right”) for each share of Common Stock, par value $0.01 (the “Common Stock”), of the Company outstanding at the close of business on February 27, 2013 (the “Record Date”). As long as the
Rights are attached to the Common Stock, the Company will issue one Right (subject to adjustment) with each new share of Common Stock so that all such shares will have attached Rights. When exercisable, each Right will entitle the registered holder
to purchase from the Company one tenth of a share of Common Stock at a price of $3.00 per one tenth of a share of Common Stock, subject to adjustment (the “Purchase Price”). The description and terms of the Rights are set forth in a
Tax Benefit Preservation Plan, dated as of February 13, 2013, as the same may be amended from time to time (the “Plan”), between the Company and American Stock Transfer & Trust Company, LLC, as Rights Agent (the
“Rights Agent”). 
 By adopting the Plan, the Board of Directors is seeking to protect certain
tax benefits of AMR, the Company and the combined enterprise (the “Combined Enterprise”) to be created upon the consummation of the transactions contemplated by the Merger Agreement, as described in the Plan (the “Tax
Benefits”). The Plan is intended to act as a deterrent to any person acquiring beneficial ownership pursuant to Section 382 of the Internal Revenue Code (the “Code”) of 4.9% or more of the outstanding shares of Common
Stock without the approval of the Board of Directors, to endeavor to protect the Tax Benefits. The Board of Directors believes it is in the best interest of the Company and its stockholders that the Company provide for the protection of the Tax
Benefits by adopting the Plan. 
 Until the close of business on the tenth (10th) business day following a
public announcement that a person or group has acquired, or obtained the right to acquire, beneficial ownership of 4.9% or more of the Common Stock (an “Acquiring Person”) or such earlier date that a majority of the Board becomes
aware of the existence of an Acquiring Person (the “Distribution Date”), the Rights will be evidenced, with respect to any of the Common Stock certificates outstanding as of the Record Date, by such Common Stock certificates or,
with respect to any uncertificated Common Stock registered in book entry form, by notation in book entry, in either case together with a copy of this Summary of Rights. The Board can postpone the Distribution Date in certain circumstances. Shares
held by persons participating in a group are deemed to be beneficially owned by all persons treated as the same entity for purposes of Section 382 of the Code. The Plan provides that any person who beneficially owned 4.9% or more of the Common
Stock immediately prior to the first public announcement of the adoption 

  
 B-1

 
of the Plan (each an “Existing Holder”), shall not be deemed to be an “Acquiring Person” for purposes of the Plan unless the Existing Holder becomes the beneficial
owner of one or more additional shares of Common Stock (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding Common Stock in Common Stock or pursuant to a split or subdivision of the outstanding Common
Stock). However, if upon acquiring beneficial ownership of one or more additional shares of Common Stock, the Existing Holder does not beneficially own 4.9% or more of the Common Stock then outstanding, the Existing Holder shall not be deemed to be
an “Acquiring Person” for purposes of the Plan. The Plan includes a procedure whereby the Board of Directors will consider requests (a) to exempt certain acquisitions of Common Stock of the Company from the applicable ownership
trigger if the Board determines that the acquisition will not jeopardize or endanger the availability of the Tax Benefits to the Company or any successor or the Combined Enterprise and (b) solely before a person beneficially owns shares of
Common Stock equal to or exceeding 4.9% of the Common Stock then outstanding, to exempt certain acquisitions of Common Stock of the Company from the applicable ownership trigger if the Board determines that the acquisition is in the best interests
of the Company or any successor or the Combined Enterprise even if it jeopardizes or endangers the availability of the Tax Benefits. 
 The Plan provides that until the Distribution Date (or earlier redemption, exchange, termination or expiration of the Rights), the Rights will be transferred with and only with the Common Stock. Until the
Distribution Date (or earlier redemption, exchange, termination or expiration of the Rights), new Common Stock certificates issued after the close of business on the Record Date upon transfer or new issuance of the Common Stock will contain a
notation incorporating the Plan by reference, and the Company will deliver a notice to that effect upon the transfer or new issuance of book entry shares. Until the Distribution Date (or earlier redemption, exchange, termination or expiration of the
Rights), the surrender for transfer of any certificates for Common Stock, with or without such notation or a copy of this Summary of Rights, will also constitute the transfer of the Rights associated with the Common Stock represented by such
certificate or the book entry shares. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Right Certificates”) will be mailed to holders of record of the Common Stock as of the close
of business on the Distribution Date and such separate Right Certificates alone will evidence the Rights. 
 The
Rights are not exercisable until the Distribution Date. The Rights will expire, unless earlier redeemed or exchanged by the Company or terminated, on the earliest to occur of: (i) February 13, 2014, subject to the Company’s right to
extend such date (the “Final Expiration Date”), (ii) the close of business on the effective date of the repeal of Section 382 or any successor statute if the Board determines that the Plan is no longer necessary or
desirable for the preservation of the Tax Benefits, (iii) the time at which the Board of Directors determines that the Tax Benefits are fully utilized or no longer available under Section 382 of the Code or that an ownership change under
Section 382 of the Code would not adversely impact in any material respect the time period in which the Company or any successor or the Combined Enterprise could use the Tax Benefits, or materially impair the amount of the Tax Benefits that
could be used by the Company or any successor or the Combined Enterprise in any particular time period, for applicable tax purposes, (iv) the time at which the Merger Agreement is terminated, or (v) immediately prior to the occurrence of
the Effective Time (as defined in the Merger Agreement). 

  
 B-2

 The Purchase Price payable, and the number of shares of Common 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 Common Stock,
(ii) upon the grant to holders of the Common Stock of certain rights or warrants to subscribe for or purchase Common Stock or convertible securities at less than the current market price of the Common Stock or (iii) upon the distribution
to holders of the Common Stock of evidences of indebtedness, cash, securities or assets (excluding regular periodic cash dividends paid out of earnings or retained earnings) or of subscription rights or warrants (other than those referred to above).

 In the event that a Person becomes an Acquiring Person or if the Company were the surviving corporation in a
merger with an Acquiring Person or any affiliate or associate of an Acquiring Person and shares of the Common Stock were not changed or exchanged, each holder of a Right, other than Rights that are or were acquired or beneficially owned by the
Acquiring Person (which Rights will thereafter be null and void), will thereafter have the right to receive upon exercise and payment of ten times the then-current Purchase Price that number of shares of Common Stock having a market value of twenty
times the then-current Purchase Price of the Right. In the event that, after a Person has become an Acquiring Person, the Company were acquired in a merger or other business combination transaction or more than 50% of its assets or earning power
were sold, proper provision shall be made so that each holder of a Right shall thereafter have the right to receive, upon the exercise and payment of ten times the then-current Purchase Price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction would have a market value of twenty times the then-current Purchase Price of the Right. 
 At any time after a Person becomes an Acquiring Person and prior to the earlier of one of the events described in the last sentence of the previous paragraph or the acquisition by such Acquiring Person of
50% or more of the outstanding Common Stock, the Board of Directors may cause the Company to exchange the Rights (other than Rights owned by an Acquiring Person which will have become null and void), in whole or in part, for Common Stock at an
exchange rate of one share of Common Stock per Right (subject to adjustment). 
 No adjustment in the Purchase
Price will be required until cumulative adjustments require an adjustment of at least 1% in such Purchase Price. No fractional Common Stock will be issued, and in lieu thereof, a payment in cash will be made based on the market price of the Common
Stock on the last trading date prior to the date of exercise. The Company will aggregate the Rights held by each record holder (and the number of shares of Common Stock represented by such Rights) in determining whether and to what extent such
record holder would otherwise be entitled to receive fractional shares of Common Stock. 
 The Rights may be
redeemed in whole, but not in part, at a price of $0.0001 per Right (the “Redemption Price”) by the Board of Directors at any time prior to the time that an Acquiring Person has become such. The redemption of the Rights may be made
effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the
holders of Rights will be to receive the Redemption Price. 

  
 B-3

 Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company beyond those as an existing stockholder, including, without limitation, the right to vote or to receive dividends. 
 Any of the provisions of the Plan may be amended by the Board of Directors, or a duly authorized committee thereof, for so long as the Rights are then redeemable, and after the Rights are no longer
redeemable, the Company may amend or supplement the Plan in any manner that does not adversely affect the interests of the holders of the Rights (other than an Acquiring Person or any affiliate or associate of an Acquiring Person). 

A copy of the Plan has been filed with the Securities and Exchange Commission as an Exhibit to a Current Report on Form
8-K. A copy of the Plan 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 Plan, which is incorporated herein by reference.
