Grand Prix Acquisition Corp. (which we refer to as "Purchaser"), a wholly-owned subsidiary of CA, Inc., a Delaware corporation (which we refer to as "Parent" or "CA") is offering to purchase for cash all of the outstanding shares of common stock, par value $0.0001 per share (the "Shares"), of Rally Software Development Corp., a Delaware corporation (which we refer to as the "Company" or "Rally") at a purchase price of $19.50 per Share (the "Offer Price"), without interest thereon, net to the seller in cash, and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings, upon the terms and subject to the conditions set forth in this Offer to Purchase (the "Offer to Purchase") and in the related Letter of Transmittal (the "Letter of Transmittal", which, together with this Offer to Purchase and other related materials, as each may be amended or supplemented from time to time in accordance with the terms of the Acquisition Agreement (as described below), constitutes the "Offer"). Under no circumstances will interest be paid on the purchase price for Shares, regardless of any extension of the Offer or any delay in making payment for Shares. The date and time at which the Offer expires by its terms (as it may be extended in accordance with the Acquisition Agreement described below) is referred to herein as the "Expiration Date" and the date and time at which Purchaser accepts Shares for payment pursuant to the Offer is referred to herein as the "Acceptance Time".

or the Merger) any applicable law that has the effect of making the consummation of any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) illegal or prohibiting or otherwise preventing the consummation of any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) or (B) issued or granted any order that remains in effect and has the effect of making any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) illegal or which has the effect of prohibiting or otherwise preventing the consummation of any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger). The Offer also is subject to other conditions as described in this Offer to Purchase. See Section 15—"Certain Conditions to the Offer". The Offer is not subject to any financing condition. On June 5, 2015, the United States Federal Trade Commission terminated early the waiting period applicable to the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger).

The Offer is being made pursuant to an Acquisition Agreement, dated as of May 27, 2015 (as it may be amended or supplemented from time to time in accordance with its terms, the "Acquisition Agreement"), by and among CA, Purchaser and Rally. The Acquisition Agreement provides, among other things, that promptly following the consummation of the Offer, subject to the satisfaction or waiver of conditions set forth in the Acquisition Agreement, Purchaser will be merged with and into Rally (the "Merger"), with Rally continuing as the surviving corporation (which we refer to as the "Surviving Corporation") of the Merger and a wholly-owned subsidiary of CA. The closing of the Merger will occur promptly after the consummation of the Offer and is referred to as the "Merger Closing." As a result of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger (the "Effective Time"), other than (i) Shares owned by CA, Purchaser, Rally or any other direct or indirect wholly-owned subsidiary of CA, Purchaser or Rally and (ii) Shares held by stockholders who have properly and validly exercised their statutory rights of appraisal in respect of such Shares in accordance with Section 262 of the General Corporation Law of the State of Delaware (the "DGCL"), will be automatically converted into the right to receive the Offer Price, without interest thereon and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings. As a result of the Merger, Rally will cease to be a publicly traded company and will become wholly-owned by CA.

After careful consideration, Rally's board of directors, among other things, has unanimously (i) determined that the Acquisition Agreement is advisable, (ii) determined that the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, taken together, are at a price and on terms that are fair to, and in the best interests of Rally and its stockholders; (iii) approved the execution, delivery and performance by Rally of the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, (iv) agreed that the Merger will be governed by Section 251(h) of the DGCL, and (v) resolved to recommend that Rally's stockholders tender their Shares to Purchaser pursuant to the Offer, all upon the terms and subject to the conditions set forth in the Acquisition Agreement.

Purchaser		Grand Prix Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of CA, Inc., a Delaware corporation

Grand Prix Acquisition Corp., referred to as "Purchaser", a wholly-owned subsidiary of CA, Inc., referred to as "Parent" or "CA", is offering to purchase for cash any and all of the outstanding shares of common stock, par value $0.0001 per share, of Rally Software Development Corp, referred to as the "Company" or "Rally." Purchaser is a Delaware corporation which was formed for the sole purpose of making the Offer and completing the process by which Purchaser will be merged with and into Rally in accordance with the Acquisition Agreement (as described below) and the General Corporation Law of the State of Delaware (the "DGCL"), referred to as the "Merger."

Unless the context indicates otherwise, in this Offer to Purchase, we use the terms "us", "we" and "our" to refer to Purchaser and, where appropriate, CA. We use the term "Parent" to refer to CA, Inc. alone, the term "Purchaser" to refer to Grand Prix Acquisition Corp. alone and the term "Rally" to refer to Rally Software Development Corp. alone.

Purchaser is offering to purchase any and all of the outstanding shares of common stock, par value $0.0001 per share, of Rally on the terms and subject to the conditions set forth in this Offer to Purchase and the Letter of Transmittal. Unless the context otherwise requires, in this Offer to Purchase we use the term "Offer" to refer to this offer and the term "Shares" to refer to shares of common stock, par value $0.0001 per share, of Rally that are the subject of the Offer.

See the "Introduction" to this Offer to Purchase and Section 1—"Terms of the Offer".

Purchaser is offering to purchase and all of the outstanding Shares on the terms and subject to the conditions set forth in this Offer to Purchase and the related Letter of Transmittal.

Purchaser is offering to pay $19.50 per Share, without interest thereon, net to the seller in cash, and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings. If you are the record owner of your Shares and you tender your Shares in the Offer, you will not have to pay brokerage fees or commissions. If you own your Shares through a broker or other nominee and your broker or other nominee tenders your Shares on your behalf, your broker or nominee may charge you a fee for doing so. You should consult your broker or nominee to determine whether any charges will apply.

See the "Introduction", Section 1—"Terms of the Offer" and Section 2—"Acceptance for Payment and Payment for Shares".

What are the material U.S. federal income tax consequences of tendering Shares?

For U.S. Holders (as defined in Section 5—"Material U.S. Federal Income Tax Consequences"), the receipt of cash in exchange for your Shares pursuant to the Offer or the Merger generally will result in the recognition of gain or loss in an amount equal to the difference, if any, between the amount of cash that such U.S. Holder receives in the Offer or the Merger and such U.S. Holder's adjusted tax basis in the Shares surrendered .

A Non-U.S. Holder (as defined in Section 5—"Material U.S. Federal Income Tax Consequences") generally will not be subject to U.S. federal income tax with respect to the exchange of common stock for cash in the Merger unless such Non-U.S. Holder has certain connections to the United States.

We urge you to consult your own tax advisor as to the particular tax consequences to you of the Offer and the Merger. See Section 5—"Material U.S. Federal Income Tax Consequences" for a more detailed discussion of the tax consequences of the Offer and the Merger.

Yes, we will have sufficient resources available to us. We estimate that we will need approximately $548 million to purchase all of the Shares pursuant to the Offer, to consummate the Merger (which estimate includes, among other things, payment in respect of outstanding in-the-money options, restricted stock units and phantom stock rights) and to pay related transaction fees and expenses. Purchaser will have sufficient cash on hand at the expiration of the Offer to pay the offer price for all Shares that are tendered in the Offer because CA will contribute or otherwise advance funds to Purchaser to enable Purchaser to pay for the Shares that are tendered in the Offer. CA intends to fund the tender offer using cash on hand, borrowings under its existing credit facility or access to capital markets. The offer is not subject to any financing conditions.

Is Purchaser's financial condition relevant to my decision to tender my Shares?

No, we do not believe Purchaser's financial condition is relevant to your decision to tender your Shares in the Offer because:

In addition, the Offer is subject to the other conditions set forth in Section 15—"Certain Conditions to the Offer". On June 5, 2015, the United States Federal Trade Commission terminated early the waiting period applicable to the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger).

The foregoing conditions are for the sole benefit of CA and Purchaser and, accordingly, may be waived by CA and Purchaser, in whole or in part, at any time and from time to time prior to the expiration of the Offer, in their sole and absolute discretion; provided, however, that the Minimum Condition can be waived only with the prior written consent of Rally.

Yes. We have agreed in the Acquisition Agreement that, subject to our rights to terminate the Acquisition Agreement in accordance with its terms:

In no event are we required to (or permitted, without the prior written consent of Rally, to) extend the Offer beyond October 27, 2015. Further, subject to our rights to terminate the Acquisition Agreement in accordance with its terms, we are not permitted to withdraw or terminate the Offer prior to any scheduled Expiration Date without the prior written consent of Rally.

See Section 1—"Terms of the Offer" of this Offer to Purchase for more details on our obligation and ability to extend the Offer.

If we extend the Offer, we will inform Computershare Trust Company, N.A., which is the depository for the Offer ("Depository"), of any extension and will issue a press release announcing the extension not later than 9:00 a.m. (Eastern Time) the business day following the date on which the Offer was scheduled to expire.

Yes. As a condition to CA's and Purchaser's willingness to enter into the Acquisition Agreement, certain directors and named executive officers of Rally, in their capacity as owners of Shares and Shares issuable upon exercise of outstanding options, restricted stock units and warrants, as applicable, entered into Support Agreements with CA (the "Support Agreements") that, among other things, obligate each of them to tender all their respective Shares in the Offer.

See Section 8—"Certain Information Concerning Parent and Purchaser" and Section 11—"The Acquisition Agreement; Other Agreements—Support Agreements".

After careful consideration, Rally's board of directors (the "Rally Board"), among other things, has unanimously:

A more complete description of the reasons for the Rally Board's approval of the Offer and the Merger is set forth in Rally's Solicitation/Recommendation Statement on Schedule 14D-9, which will be filed with the SEC and is being mailed to Rally's stockholders with this Offer to Purchase.

If you hold your Shares directly as the registered owner, you can tender your Shares in the Offer not later than the Expiration Date:

The Letter of Transmittal is enclosed with this Offer to Purchase. If you hold your Shares in street name through a broker, dealer, commercial bank, trust company or other nominee, you must contact the institution that holds your Shares and give instructions that your Shares be tendered. You should contact the institution that holds your Shares for more details. If you cannot deliver everything required to make a valid tender to the Depository before the Expiration Date, you may have a limited amount of additional time by having a financial institution (including most banks, savings and loan associations and brokerage houses) that is a member of a recognized Medallion Program approved by The Securities Transfer Association Inc., including the Securities Transfer Agents Medallion Program (STAMP), the Stock Exchange Medallion Program (SEMP) and The New York Stock Exchange Medallion Signature Program (MSP), guarantee, pursuant to a Notice of Guaranteed Delivery, that the missing items will be received by the Depository within three New York Stock Exchange (the "NYSE") trading days. However, the Depository must receive the missing items within that three NYSE trading day period.

You will have until 12:01 a.m. (Eastern Time) on July 8, 2015 to tender your Shares in the Offer, unless we extend the Offer pursuant to the terms of the Acquisition Agreement (the date and time at which the Offer expires by its terms (as it may be extended in accordance with the Acquisition Agreement), the "Expiration Date") or the Offer is earlier terminated in the event that the Acquisition Agreement is terminated.

See Section 1—"Terms of the Offer" and Section 3—"Procedures for Accepting the Offer and Tendering Shares".

Yes. To withdraw previously tendered Shares, you must deliver a written notice of withdrawal with the required information to the Depository while you still have the right to withdraw Shares. If you tendered Shares by giving instructions to a broker, banker or other nominee, you must instruct the broker, banker or other nominee to arrange for the withdrawal of your Shares.

You may withdraw your previously tendered Shares at any time prior to 12:01 a.m. (Eastern Time) on July 8, 2015, or such later date as the Offer may be extended and, unless accepted for payment by Purchaser pursuant to the Offer, pursuant to Section 14(d)(5) of the Exchange Act, previously tendered Shares may also be withdrawn at any time after withdrawn at any time after the date that is 60 days from the date of the Offer to Purchase.

If the Offer is consummated, we intend to consummate the Merger promptly thereafter. No vote of Rally's stockholders will be required to consummate the Merger. If the Merger is consummated, Rally will no longer be publicly traded.

If I decide not to tender my Shares in the Offer, how will the Offer affect my Shares?

If the Offer is consummated and certain other conditions are met, the Merger will be consummated promptly thereafter and all of the Shares then outstanding (other than Shares held by CA, Purchaser, Rally or any other direct or indirect wholly-owned subsidiary of CA, Purchaser or Rally or Shares held by stockholders who have properly and validly exercised their statutory rights of appraisal in respect of such Shares in accordance with Section 262 of the DGCL) will be converted into the right to receive the Offer Price, without interest thereon and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings. Therefore, if the Offer and the Merger are consummated, the only difference between tendering your Shares in the Offer and not tendering your Shares in the Offer is that you will be paid somewhat earlier if you tender your Shares in the Offer.

See the "Introduction" to this Offer to Purchase and Section 13—"Certain Effects of the Offer".

No appraisal rights will be available to you in connection with the Offer. However, subject to and in accordance with Delaware law, holders of Shares will be entitled to appraisal rights in connection with the Merger if they do not tender Shares in the Offer and properly perfect their right to seek appraisal under Delaware law in connection with the Merger.

Grand Prix Acquisition Corp. (which we refer to as "Purchaser"), a wholly-owned subsidiary of CA, Inc., a Delaware corporation (which we refer to as "Parent" or "CA") is offering to purchase for cash all of the outstanding shares of common stock, par value $0.0001 per share (the "Shares"), of Rally Software Development Corp., a Delaware corporation (which we refer to as the "Company" or "Rally") at a purchase price of $19.50 per Share (the "Offer Price"), without interest thereon, net to the seller in cash, and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings, upon the terms and subject to the conditions set forth in this Offer to Purchase (the "Offer to Purchase") and in the related Letter of Transmittal (the "Letter of Transmittal" which, together with this Offer to Purchase and other related materials, as each may be amended or supplemented from time to time in accordance with the terms of the Acquisition Agreement (as described below), constitutes the "Offer"). Under no circumstances will interest be paid on the purchase price for Shares, regardless of any extension of the Offer or any delay in making payment for Shares. The date and time at which the Offer expires by its terms (as it may be extended in accordance with the Acquisition Agreement described below) is referred to herein as the "Expiration Date" and the date and time at which Purchaser accepts Shares for payment pursuant to the Offer is referred to herein as the "Acceptance Time".

Tendering stockholders who are record owners of their Shares and who tender directly to Computershare Trust Company, N.A. (the "Depository") will not be obligated to pay brokerage fees or commissions or, except as otherwise provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes with respect to the purchase of Shares by Purchaser pursuant to the Offer. Stockholders who hold their Shares through a broker, banker or other nominee should consult such institution as to whether it charges any service fees or commissions.

Purchaser will not be required to (and may not) accept any Shares for payment pursuant to the Offer, unless, at the Expiration Date, the number of Shares validly tendered in accordance with the terms of the Offer (after giving effect to any withdrawals of previously tendered Shares), taken together with any Shares then owned by CA and Purchaser, represent a majority of all then outstanding Shares (excluding Shares tendered pursuant to guaranteed delivery procedures that have not yet been "received", as such term is defined in Section 251(h) of the DGCL, by the depository for the Offer pursuant to such procedures). In addition, Purchaser will not be required to accept any Shares for payment pursuant to the Offer if, at the Expiration Date, (i) Rally has breached its covenants under the Acquisition Agreement in any material respect, (ii) a "Company Material Adverse Effect" (as defined in the Acquisition Agreement) has occurred and is continuing, or (iii) a governmental authority has (A) enacted, issued, promulgated, entered, enforced or deemed applicable to any of the transactions contemplated by the Acquisition Agreement (including the Offer or the Merger) any applicable law that has the effect of making the consummation of any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) illegal or prohibiting or otherwise preventing the consummation of any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) or (B) issued or granted any order that remains in effect and has the effect of making any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) illegal or which has the effect of prohibiting or otherwise preventing the consummation of any of the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger). The Offer also is subject to other conditions as described in this Offer to Purchase. See Section 15—"Certain Conditions to the Offer". The Offer is not subject to any financing condition. On June 5, 2015, the United States Federal Trade Commission terminated early the waiting

period applicable to the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger).

The Offer is being made pursuant to an Acquisition Agreement, dated as of May 27, 2015 (as it may be amended or supplemented from time to time in accordance with its terms, the "Acquisition Agreement"), by and among CA, Purchaser and Rally. The Acquisition Agreement provides, among other things, that promptly following the consummation of the Offer, subject to the satisfaction or waiver of conditions set forth in the Acquisition Agreement, Purchaser will be merged with and into Rally (the "Merger"), with Rally continuing as the surviving corporation (the "Surviving Corporation") of the Merger and a wholly-owned subsidiary of CA. The closing of the Merger will occur promptly after the consummation of the Offer and is referred to as the "Merger Closing." As a result of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger (the "Effective Time"), other than (i) Shares owned by CA, Purchaser, Rally or any other direct or indirect wholly-owned subsidiary of CA, Purchaser or Rally and (ii) Shares held by stockholders who have properly and validly exercised their statutory rights of appraisal in respect of such Shares in accordance with Section 262 of the General Corporation Law of the State of Delaware (the "DGCL"), will be automatically converted into the right to receive the Offer Price, without interest thereon and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings. As a result of the Merger, Rally will cease to be a publicly traded company and will become wholly-owned by CA.

After careful consideration, Rally's board of directors (the "Rally Board"), among other things, has unanimously (i) determined that the Acquisition Agreement is advisable, (ii) determined that the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, taken together, are at a price and on terms that are fair to, and in the best interests of Rally and its stockholders; (iii) approved the execution, delivery and performance by Rally of the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, (iv) agreed that the Merger will be governed by Section 251(h) of the DGCL, and (v) resolved to recommend that Rally's stockholders tender their Shares to Purchaser pursuant to the Offer, all upon the terms and subject to the conditions set forth in the Acquisition Agreement (the "Company Board Recommendation").

A more complete description of the Rally Board's reasons for authorizing and approving the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, is set forth in Rally's Solicitation/Recommendation Statement on Schedule 14D-9 (together with any exhibits and annexes attached thereto, the "Schedule 14D-9") that is being furnished to stockholders in connection with the Offer. Stockholders should carefully read the information set forth in the Schedule 14D-9, including the information set forth under "Item 4. The Solicitation or Recommendation".

Rally has advised CA that, on June 2, 2015, (a) 25,647,582 Shares were issued and outstanding, (b) 945,443 Shares were issuable upon the exercise of outstanding stock options of Rally granted under any of Rally's Amended and Restated 2002 Stock Option Plan and 2013 Equity Incentive Plan (each, a "Stock Plan" and collectively, the "Stock Plans") to purchase Shares ("Options") that were vested ("Vested Options"), (c) 1,034,734 Shares were subject to restricted stock units of Rally granted under any of the Stock Plans ("RSU"), (d) 190,000 Shares were estimated to be subject to outstanding rights under the 2013 Employee Stock Purchase Plans and (e) 7,951 Shares were issuable upon the exercise of outstanding warrants to purchase Shares ("Warrants"). The Minimum Condition would be satisfied if at the Expiration Date, there will have been validly tendered in accordance with the terms of the Offer (after giving effect to any withdrawals of previously tendered shares) a number of Shares that, taken together with any Shares then owned by CA and Purchaser, represent a majority of all then outstanding Shares (excluding Shares tendered pursuant to guaranteed delivery procedures that have

not yet been "received", as such term is defined in Section 251(h) of the DGCL, by the Depository pursuant to such procedures).

Pursuant to the Acquisition Agreement, at the Effective Time, (a) the members of the board of directors of Purchaser immediately prior to the Effective Time will become the initial directors of the Surviving Corporation and (b) the officers of Purchaser immediately prior to the Effective Time will become the initial officers of the Surviving Corporation, in each case to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors have been duly elected, appointed or qualified.

Upon the consummation of the Offer, Purchaser will have acquired a sufficient number of Shares to approve the Merger without a vote of the stockholders of Rally pursuant to Section 251(h) of the DGCL. Therefore, the parties have agreed to take all necessary and lawful actions to cause the Merger to become effective, without a meeting of the stockholders of Rally, in accordance with Section 251(h) of the DGCL.

The material U.S. federal income tax consequences of the sale of Shares pursuant to the Offer and the exchange of Shares in the Merger are described in Section 5—"Material U.S. Federal Income Tax Consequences".

This Offer to Purchase and the related Letter of Transmittal contain important information that should be read carefully before any decision is made with respect to the Offer.

Upon the terms and subject to the conditions to the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), we will accept for payment and promptly pay for all Shares validly tendered prior to the Expiration Date and not withdrawn as permitted under Section 4—"Withdrawal Rights".

The date and time at which Purchaser accepts Shares for payment pursuant to the Offer is referred to herein as the "Acceptance Time", which will occur promptly following the expiration of the Offer (which is expected to be at 12:01 a.m. (Eastern Time) on July 8, 2015 (the date and time at which the Offer expires by its terms (as it may be extended in accordance with the Acquisition Agreement), the "Expiration Date"). The time at which the Merger becomes effective is referred to herein as the "Effective Time."

The Offer is conditioned upon, among other things, the satisfaction of the Minimum Condition, the Governmental Authority Condition and the other conditions described in Section 15—"Certain Conditions to the Offer".

The Expiration Date may be extended in certain circumstances, subject to CA's right to terminate the Acquisition Agreement in accordance with its terms, in accordance with the Acquisition Agreement, including that: (i) Purchaser will (and CA will cause Purchaser to) extend the Offer for any period required by any rule, regulation or other requirement of the Securities and Exchange Commission (the "SEC") (or its staff) that is applicable to the Offer or any rule or regulation of the New York Stock Exchange (the "NYSE") that is applicable to the Offer; and (ii) in the event that any of the conditions to the Offer are not satisfied or waived as of any scheduled Expiration Date, Purchaser may (but will not be required to) extend the Offer for one or more successive extension periods of up to ten business days each in order to further seek to satisfy the conditions to the Offer. In no event is Purchaser required to (or permitted, without the prior consent of Rally, to) extend the Offer beyond October 27, 2015. Further, subject to CA's rights to terminate the Acquisition Agreement in accordance with its terms, Purchaser is not permitted to withdraw or terminate the Offer prior to any scheduled Expiration Date without the prior written consent of Rally.

CA and Purchaser may increase the Offer Price or otherwise amend, modify, or make changes to the terms and conditions of the Offer; provided, however, that unless otherwise provided by the Acquisition Agreement or previously approved by Rally in writing, neither CA nor Purchaser may make any change to the terms and conditions of the Offer that (i) decreases the Offer Price; (ii) changes the form of consideration to be paid in the Offer; (iii) reduces the number of Shares sought to be purchased in the Offer; (iv) waives, amends, modifies or otherwise changes the Minimum Condition; (v) amends, modifies or otherwise changes any conditions to the Offer (other than the Minimum Condition) in a manner that adversely impacts or reasonably could adversely impact Rally's stockholders in any material respect; (vi) imposes conditions to the Offer that are in addition to the conditions to the Offer set forth in the Acquisition Agreement; (vii) extends or otherwise changes the Expiration Date in a manner other than as required or permitted by the Acquisition Agreement; or (viii) provides for any "subsequent offering period" within the meaning of Rule 14d-11 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Any extension, delay, termination or amendment of the Offer will be followed as promptly as practicable by public announcement thereof, and such announcement in the case of an extension will be made no later than 9:00 a.m. (Eastern Time) on the business day following the date on which the Offer was scheduled to expire. Without limiting the manner in which Purchaser may choose to make any public announcement, it currently intends to make announcements regarding the Offer by issuing a press release and making any appropriate filing with the SEC.

If we extend the Offer, are delayed in our acceptance for payment of or payment (whether before or after our acceptance for payment for Shares) for Shares or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer and the Acquisition Agreement, the Depository may retain tendered Shares on our behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described herein under Section 4—"Withdrawal Rights". However, our ability to delay the payment for Shares that we have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires us to promptly pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer.

If we make a material change in the terms of the Offer or the information concerning the Offer or if we waive a material condition of the Offer, we will disseminate additional tender offer materials and extend the Offer if and to the extent required by Rules 14d-4(d)(1), 14d-6(c) and 14e-1 under the Exchange Act. The minimum period during which an offer must remain open following material changes in the terms of the Offer or information concerning the Offer, other than a change in price or a change in percentage of securities sought, will depend upon the facts and circumstances, including the relative materiality of the terms or information changes. We understand that in the SEC's view, an offer should remain open for a minimum of five business days from the date the material change is first published, sent or given to stockholders, and with respect to a change in price or a change in percentage of securities sought, a minimum ten business day period generally is required to allow for adequate dissemination to stockholders and investor response.

If, on or before the Expiration Date, we increase the consideration being paid for Shares accepted for payment in the Offer, such increased consideration will be paid to all stockholders whose Shares are purchased in the Offer, whether or not such Shares were tendered before the announcement of the increase in consideration.

We expressly reserve the right, in our sole and absolute discretion, subject to the terms and conditions of the Acquisition Agreement and the applicable rules and regulations of the SEC, not to accept for payment any Shares if, at the Expiration Date, any of the conditions to the Offer have not been satisfied. See Section 15—"Certain Conditions to the Offer".

Under certain circumstances, we may terminate the Acquisition Agreement and the Offer. Without limiting the generality of the foregoing, subject to certain exceptions, we may terminate the Acquisition Agreement if:

Rally has provided us with Rally's stockholder list and security position listings for the purpose of disseminating this Offer to Purchase, the related Letter of Transmittal and other related materials to holders of Shares. This Offer to Purchase and the related Letter of Transmittal will be mailed to record holders of Shares whose names appear on Rally's stockholder list and will be furnished, for subsequent transmittal to beneficial owners of Shares, to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency's security position listing for subsequent transmittal to beneficial owners of Shares.

Subject to the satisfaction or waiver of all the conditions to the Offer set forth in Section 15—"Certain Conditions to the Offer", we will accept for payment and promptly pay for Shares validly tendered and not withdrawn pursuant to the Offer on or after the Expiration Date. Subject to compliance with Rule 14e-1(c) under the Exchange Act, we expressly reserve the right to delay payment for Shares in order to comply in whole or in part with any applicable law. See Section 16—"Certain Legal Matters; Regulatory Approvals".

In all cases, we will pay for Shares tendered and accepted for payment pursuant to the Offer only after timely receipt by the Depository of (i) (A) the certificates evidencing such Shares (the "Share Certificates") or (B) confirmation of a book-entry transfer of such Shares (a "Book-Entry Confirmation") into the Depository's account at The Depository Trust Company ("DTC") pursuant to the procedures set forth in Section 3—Procedures for Accepting the Offer and Tendering Shares", (ii) the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees or, in the case of a book-entry transfer, an Agent's Message (as described below) in lieu of the Letter of Transmittal and (iii) any other documents required by the Letter of Transmittal. Accordingly, tendering stockholders may be paid at different times depending upon when Share Certificates or Book-Entry Confirmations with respect to Shares are actually received by the Depository.

The term "Agent's Message" means a message, transmitted by DTC to and received by the Depository and forming a part of a Book-Entry Confirmation, that states that DTC has received an express acknowledgment from the participant in DTC tendering the Shares that are the subject of such Book-Entry Confirmation, that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that Purchaser may enforce such agreement against such participant.

On the terms of and subject to the conditions to the Offer, promptly after the Expiration Date, we will accept for payment, and pay for, all Shares validly tendered to us in the Offer and not validly withdrawn on or prior to the Expiration Date of the Offer. For purposes of the Offer, we will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered and not validly withdrawn as, if and when we give oral or written notice to the Depository of our acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions to the

Offer, payment for Shares accepted for payment pursuant to the Offer will be made by deposit of the Offer Price for such Shares with the Depository, which will act as paying agent for tendering stockholders for the purpose of receiving payments from us and transmitting such payments to tendering stockholders whose Shares have been accepted for payment. If we extend the Offer, are delayed in our acceptance for payment of Shares or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer and the Acquisition Agreement, the Depository may retain tendered Shares on our behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described herein under Section 4—"Withdrawal Rights" and as otherwise required by Rule 14e-1(c) under the Exchange Act. Under no circumstances will we pay interest on the purchase price for Shares by reason of any extension of the Offer or any delay in making such payment for Shares.

Shares tendered by Notice of Guaranteed Delivery will not be deemed validly tendered for purposes of satisfying the Minimum Condition unless and until Shares underlying such Notice of Guaranteed Delivery are received by the Depository pursuant to Section 251(h) of the DGCL or unless otherwise mutually agreed by Rally and us.

If any tendered Shares are not accepted for payment for any reason pursuant to the terms and conditions to the Offer, or if Share Certificates are submitted evidencing more Shares than are tendered, Share Certificates evidencing unpurchased Shares will be returned, without expense to the tendering stockholder (or, in the case of Shares tendered by book-entry transfer into the Depository's account at DTC pursuant to the procedure set forth in Section 3—"Procedures for Accepting the Offer and Tendering Shares", such Shares will be credited to an account maintained at DTC), promptly following the expiration or termination of the Offer.

Valid Tenders. In order for a stockholder to validly tender Shares pursuant to the Offer, the Letter of Transmittal, properly completed and duly executed, together with any required signature guarantees (or, in the case of a book-entry transfer, an Agent's Message in lieu of the Letter of Transmittal) and any other documents required by the Letter of Transmittal must be received by the Depository at one of its addresses set forth on the back cover of this Offer to Purchase and either (A) the Share Certificates evidencing tendered Shares must be received by the Depository at such address, (B) such Shares must be tendered pursuant to the procedure for book-entry transfer described below and a Book-Entry Confirmation must be received by the Depository, or (C) the guaranteed delivery procedure described below must be complied with, in each case prior to the Expiration Date.

Book-Entry Transfer. The Depository will establish an account with respect to the Shares at DTC for purposes of the Offer within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in the system of DTC may make a book-entry delivery of Shares by causing DTC to transfer such Shares into the Depository's account at DTC in accordance with DTC's procedures for such transfer. However, although delivery of Shares may be effected through book-entry transfer at DTC, either the Letter of Transmittal, properly completed and duly executed, together with any required signature guarantees, or an Agent's Message in lieu of the Letter of Transmittal, and any other required documents, must, in any case, be received by the Depository at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Date, or the guaranteed delivery procedure described below must be complied with. Delivery of documents to DTC does not constitute delivery to the Depository.

Guaranteed Delivery. If you wish to tender Shares pursuant to the Offer and cannot deliver such Shares and all other required documents to the Depository by the Expiration Date or cannot complete

the procedure for delivery by book-entry transfer on a timely basis, you may nevertheless tender such Shares if all of the following conditions are met:

The Notice of Guaranteed Delivery may be delivered or transmitted by telegram, telex, facsimile transmission or mail to the Depository and must include a guarantee by an Eligible Institution in the form set forth in such Notice of Guaranteed Delivery.

Guarantee of Signatures. No signature guarantee is required on the Letter of Transmittal (i) if the Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this Section 3, includes any participant in DTC's systems whose name appears on a security position listing as the owner of the Shares) of the Shares tendered therewith, unless such registered holder has completed either the box entitled "Special Payment Instructions" or the box entitled "Special Delivery Instructions" on the Letter of Transmittal or (ii) if the Shares are tendered for the account of a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a member in good standing of the Securities Transfer Agents Medallion Program or any other "eligible guarantor institution", as such term is defined in Rule 17Ad-15 of the Exchange Act (each, an "Eligible Institution" and, collectively, the "Eligible Institutions"). In all other cases, all signatures on a Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 1 of the Letter of Transmittal. If a Share Certificate is registered in the name of a person or persons other than the signer of the Letter of Transmittal, or if payment is to be made or delivered to, or a Share Certificate not accepted for payment or not tendered is to be issued in, the name of a person other than the registered holder, then the Share Certificate must be endorsed or accompanied by duly executed stock powers, in either case signed exactly as the name of the registered holder appears on the Share Certificate, with the signature on such Share Certificate or stock powers guaranteed by an Eligible Institution as provided in the Letter of Transmittal. See Instructions 1 and 5 of the Letter of Transmittal.

Notwithstanding any other provision of this Offer to Purchase, payment for Shares accepted pursuant to the Offer will in all cases only be made after timely receipt by the Depository of (i) (A) Share Certificates evidencing such Shares or (B) a Book-Entry Confirmation of a book-entry transfer of such Shares into the Depository's account at DTC pursuant to the procedures set forth in this Section 3, (ii) the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees or, in the case of a book-entry transfer, an Agent's Message in lieu of the Letter of Transmittal and (iii) any other documents required by the Letter of Transmittal. Accordingly, tendering stockholders may be paid at different times depending upon when Share Certificates or Book-Entry Confirmations with respect to Shares are actually received by the Depository.

The method of delivery of Share Certificates, the Letter of Transmittal and all other required documents, including delivery through DTC, is at the option and risk of the tendering stockholder, and the delivery of all such documents will be deemed made (and the risk of loss and the title of Share Certificates will pass) only when actually received by the Depository (including, in the case of a book-entry transfer, receipt of a Book-Entry Confirmation). If delivery is by mail, registered mail with

return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery prior to the Expiration Date.

Irregularities. The tender of Shares pursuant to any one of the procedures described above will constitute the tendering stockholder's acceptance of the Offer, as well as the tendering stockholder's representation and warranty that such stockholder has the full power and authority to tender and assign the Shares tendered, as specified in the Letter of Transmittal. Our acceptance for payment of Shares tendered pursuant to the Offer will constitute a binding agreement between the tendering stockholder and us upon the terms and subject to the conditions to the Offer (and if the Offer is extended or amended, the terms of or the conditions to any such extension or amendment).

Determination of Validity. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by us, in our sole discretion. We reserve the absolute right to reject any and all tenders determined by us not to be in proper form or the acceptance for payment of which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been waived or cured within such time as we will determine. None of Purchaser, the Depository, Innisfree M&A Incorporated (the "Information Agent") or any other person will be under any duty to give notice of any defects or irregularities in tenders or incur any liability for failure to give any such notice. Any determination made by us with respect to the terms and conditions to the Offer may be challenged by Rally's stockholders, to the extent permitted by law, and are subject to review by a court of competent jurisdiction.

Appointment. By executing the Letter of Transmittal as set forth above, the tendering stockholder will irrevocably appoint designees of Purchaser as such stockholder's attorneys-in-fact and proxies in the manner set forth in the Letter of Transmittal, each with full power of substitution, to the full extent of such stockholder's rights with respect to the Shares tendered by such stockholder and accepted for payment by Purchaser and with respect to any and all other Shares or other securities or rights issued or issuable in respect of such Shares. All such powers of attorney and proxies will be considered irrevocable and coupled with an interest in the tendered Shares. Such appointment will be effective when, and only to the extent that, we accept for payment Shares tendered by such stockholder as provided herein. Upon such appointment, all prior powers of attorney, proxies and consents given by such stockholder with respect to such Shares or other securities or rights will, without further action, be revoked and no subsequent powers of attorney, proxies, consents or revocations may be given by such stockholder (and, if given, will not be deemed effective). The designees of Purchaser will thereby be empowered to exercise all voting and other rights with respect to such Shares and other securities or rights, including, without limitation, in respect of any annual, special or adjourned meeting of Rally's stockholders, actions by written consent in lieu of any such meeting or otherwise, as they in their sole discretion deem proper.

We reserve the right to require that, in order for Shares to be deemed validly tendered, immediately upon our acceptance for payment of such Shares, Purchaser or its designees must be able to exercise full voting, consent and other rights with respect to such Shares and other related securities or rights, including voting at any meeting of Rally's stockholders.

Information Reporting and Backup Withholding. Payments made to stockholders of Rally in the Offer or the Merger generally will be subject to information reporting and may be subject to backup withholding. To avoid backup withholding, U.S. stockholders that do not otherwise establish an exemption should complete and return the Internal Revenue Service ("IRS") Form W-9 included in the Letter of Transmittal, certifying that such stockholder is a United States person, the taxpayer identification number provided is correct, and that such stockholder is not subject to backup

withholding. Non-U.S. stockholders should submit an appropriate and properly completed IRS Form W-8 in order to avoid backup withholding. Such stockholders should consult a tax advisor to determine which IRS Form W-8 is appropriate.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a stockholder's United States federal income tax liability, provided the required information is timely furnished in the appropriate manner to the IRS.

Except as otherwise provided in this Section 4, tenders of Shares made pursuant to the Offer are irrevocable.

Shares tendered pursuant to the Offer may be withdrawn at any time prior to 12:01 a.m. (Eastern Time) on the Expiration Date and, unless theretofore accepted for payment by Purchaser pursuant to the Offer, may also be withdrawn at any time after the date that is 60 days from the date of the Offer to Purchase.

For a withdrawal to be effective, a written notice of withdrawal must be timely received by the Depository at one of its addresses set forth on the back cover page of this Offer to Purchase. Any such notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of such Shares, if different from that of the person who tendered such Shares. If Share Certificates evidencing Shares to be withdrawn have been delivered or otherwise identified to the Depository, then, prior to the physical release of such Share Certificates, the serial numbers shown on such Share Certificates must be submitted to the Depository and the signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution, unless such Shares have been tendered for the account of an Eligible Institution. If Shares have been tendered pursuant to the procedure for book-entry transfer as set forth in Section 3—"Procedures for Accepting the Offer and Tendering Shares", any notice of withdrawal must also specify the name and number of the account at DTC to be credited with the withdrawn Shares.

Withdrawals of Shares may not be rescinded. Any Shares validly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered by again following one of the procedures described in Section 3—"Procedures for Accepting the Offer and Tendering Shares" at any time prior to the Expiration Date.

We will determine, in our sole discretion, all questions as to the form and validity (including time of receipt) of any notice of withdrawal. None of Purchaser, the Depository, the Information Agent or any other person will be under any duty to give notice of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

The following discussion is a summary of material U.S. federal income tax consequences of the Offer and the Merger that may be relevant to U.S. Holders and Non-U.S. Holders (each as defined below) whose Shares are tendered and accepted for payment pursuant to the Offer or whose Shares are converted into the right to receive cash in the Merger. This discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated under the Code, court decisions, published positions of the Internal Revenue Service (the "IRS"), and other applicable authorities, all as in effect on the date of this proxy statement and all of which are subject to change or differing interpretations, possibly with retroactive effect. This discussion is limited to holders who hold their shares of common stock as "capital assets" within the meaning of Section 1221 of the Code (generally, property held for investment purposes).

This discussion is for general information only and does not address all of the tax consequences that may be relevant to holders in light of their particular circumstances. For example, this discussion does not address:

If a partnership (including an entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of Shares, then the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partner and the partnership. Partnerships holding Shares and partners therein should consult their tax advisors regarding the consequences of the Offer and the Merger.

No ruling has been or will be obtained from the IRS regarding the U.S. federal income tax consequences of the Offer or the Merger described below, nor will counsel to Purchaser or Rally render a tax opinion in connection with the Offer or the Merger. If the IRS contests a conclusion set forth herein, no assurance can be given that a holder would ultimately prevail in a final determination by a court.

THIS DISCUSSION IS PROVIDED FOR GENERAL INFORMATION ONLY AND DOES NOT CONSTITUTE LEGAL ADVICE TO ANY HOLDER. A HOLDER SHOULD CONSULT ITS OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES RELATING TO THE OFFER AND THE MERGER IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES AND ANY CONSEQUENCES ARISING UNDER FEDERAL NON-INCOME TAX LAWS OR THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION.

For purposes of this discussion, a "U.S. Holder" is a beneficial owner of shares of common stock that is for U.S. federal income tax purposes:

The receipt of cash by a U.S. Holder in exchange for Shares pursuant to the Offer or the Merger will be a taxable transaction for U.S. federal income tax purposes. In general, such U.S. Holder's gain or loss will be equal to the difference, if any, between the amount of cash received and the U.S. Holder's adjusted tax basis in the Shares surrendered. A U.S. Holder's adjusted tax basis generally will equal the amount that such U.S. Holder paid for the Shares. Such gain or loss will be capital gain or loss and will be long-term capital gain or loss if such U.S. Holder's holding period in such Shares is more than one year. A reduced tax rate on capital gain generally will apply to long-term capital gain of a non-corporate U.S. Holder (including individuals). Short-term capital gain is taxed at ordinary income rates. The deductibility of capital losses is subject to limitations.

For purposes of this discussion, the term "Non-U.S. Holder" means a beneficial owner of Shares that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.

Any gain realized by a Non-U.S. Holder pursuant to the Offer or the Merger generally will not be subject to U.S. federal income tax unless:

A U.S. Holder or Non-U.S. Holder who exchanges Shares pursuant to the Offer or the Merger is subject to information reporting and may be subject to backup withholding unless certain information is provided to the Depository or an exemption applies. See Section 3—"Procedures for Accepting the Offer and Tendering Shares".

The Shares currently trade on the NYSE under the symbol "RALY" and have been traded since April 12, 2013.

On June 5, 2015, the last full trading day before the commencement of the Offer, the reported closing sales price of the Shares on the NYSE was $19.41.

According to Rally's Annual Report on Form 10-K for the fiscal year ended January 31, 2015, Rally has never declared or paid any cash dividends on its common stock. Stockholders are urged to obtain a current market quotation for the Shares.

Although neither CA nor Purchaser has any knowledge that any such information is untrue, neither CA nor Purchaser takes any responsibility for the accuracy or completeness of information contained in this Offer to Purchase with respect to Rally or any of its subsidiaries or affiliates or for any failure by Rally to disclose any events which may have occurred or may affect the significance or accuracy of any such information.

CA is one of the world's leading providers of information technology (IT) management software and solutions, and CA's solutions help organizations of all sizes plan, develop, manage, and secure applications and IT infrastructure that increase productivity and enhance competitiveness in their businesses. The following description of CA and its business has been taken from CA's Annual Report on Form 10-K for the fiscal year ended March 31, 2015 and is qualified in its entirety by reference to such Form 10-K.

Purchaser is a Delaware corporation incorporated on May 26, 2015. Purchaser was formed solely for the purpose of completing the proposed Offer and Merger and has conducted no business activities other than those related to the structuring and negotiating of the Offer and the Merger. Purchaser has minimal assets and liabilities other than the contractual rights and obligations related to the Acquisition Agreement. Upon the completion of the Merger, Purchaser will cease to exist and Rally will continue as the Surviving Corporation. Until immediately prior to the time Purchaser purchases Shares pursuant to the Offer, it is not anticipated that Purchaser will have any significant assets or liabilities or engage in activities other than those incidental to their formation and capitalization and the transactions contemplated by the Offer and the Merger.

The principal offices of CA and Purchaser are located at 520 Madison Avenue 22^nd Floor, New York, New York 10022, and the telephone number of CA and Purchaser is 1-800-225-5224. The name,

citizenship, business address, present principal occupation or employment and five-year employment history of each of the members, directors or executive officers of Purchaser and CA are listed in Schedule I to this Offer to Purchase.

During the last five years, none of Purchaser or CA or, to the best knowledge of Purchaser and CA, any of the persons listed in Schedule I to this Offer to Purchase (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to any judicial or administrative proceeding (except for matters that were dismissed without sanction or settlement) that resulted in a judgment, decree or final Order enjoining such person from future violations of, or prohibiting activities subject to, federal or state securities laws, or a finding of any violation of such laws.

Except as described above or in Schedule I hereto, (i) none of Purchaser or CA or, to the best knowledge of Purchaser and CA, any of the persons listed in Schedule I to this Offer to Purchase beneficially owns or has any right to acquire, directly or indirectly, any Shares and (ii) none of CA, Purchaser or, to the best knowledge of Purchaser and CA, any of the persons or entities referred to in Schedule I hereto nor any director, executive officer or subsidiary of any of the foregoing has effected any transaction in respect of any Shares during the past sixty days. Notwithstanding the foregoing, in conjunction with entering into the Acquisition Agreement, CA and Purchaser also entered into the Support Agreements (as described in Section 11—"The Acquisition Agreement; Other Agreements—Support Agreements") with the directors and named executive officers of Rally, who in the aggregate, beneficially owned 5.9% of the Shares as of May 27, 2015, and, accordingly, CA and Purchaser may be deemed to have beneficial ownership over such Shares under the Exchange Act and the rules promulgated thereunder, which define beneficial ownership in part as any person, directly or indirectly, through any contract, having or sharing voting power with respect to an entity's securities.

Except as provided in the Acquisition Agreement or as otherwise described in this Offer to Purchase, none of Purchaser or CA or, to the best knowledge of Purchaser and CA, any of the persons listed in Schedule I to this Offer to Purchase, has any contract, arrangement, understanding or relationship with any other person with respect to any securities of Rally (including, but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or the voting of any such securities, joint ventures, loan or option arrangements, puts or calls, guaranties of loans, guaranties against loss, or the giving or withholding of proxies, consents or authorizations).

Except as set forth in this Offer to Purchase, none of Purchaser or CA or, to the best knowledge of Purchaser and CA, any of the persons listed in Schedule I hereto, has had any business relationship or transaction with Rally or any of its executive officers, directors or affiliates that is required to be reported under the rules and regulations of the SEC applicable to the Offer. Except as set forth in this Offer to Purchase, there have been no contacts, negotiations or transactions between CA or any of its subsidiaries or, to the best knowledge of Purchaser and CA, any of the persons listed in Schedule I to this Offer to Purchase, on the one hand, and Rally or its affiliates, on the other hand, concerning a merger, consolidation or acquisition, tender offer or other acquisition of securities, an election of directors or a sale or other transfer of a material amount of assets during the past two years.

Available Information. The summary information of CA is qualified in its entirety by reference to CA's public filings with the SEC and should be considered in conjunction with the more comprehensive financial and other information in such reports and other publicly available information. Pursuant to Rule 14d-3 under the Exchange Act, we have filed with the SEC a Tender Offer Statement on Schedule TO (the "Schedule TO"), of which this Offer to Purchase forms a part, and exhibits to the Schedule TO. CA's public filings and the Schedule TO and the exhibits thereto, as well as other information filed by Parent and Purchaser with the SEC, are available for inspection at the SEC at 100 F Street, N.E., Washington, D.C. 20549. Please call the SEC at 1-800-SEC-0330 for further information. Copies of such information may be obtainable by mail, upon payment of the SEC's

customary charges, by writing to the SEC at the address above. The SEC also maintains a web site on the Internet at www.sec.gov that contains the Schedule TO and the exhibits thereto and other information that Purchaser and/or Parent have filed electronically with the SEC.

Purchaser believes that the financial condition of CA, Purchaser and their respective affiliates is not material to a decision by a holder of Shares whether to tender such Shares in the Offer because (i) Purchaser was organized solely in connection with the Offer and the Merger and, prior to the Expiration Date, will not carry on any activities other than in connection with the Offer and the Merger; (ii) the Offer is being made for all outstanding Shares solely for cash; (iii) if Purchaser consummates the Offer, Purchaser expects to acquire all remaining Shares for the same cash price in the Merger that was paid for Shares validly tendered and not withdrawn pursuant to the Offer; and (iv) CA will cause Purchaser to have sufficient funds available to consummate the purchase of the Shares in the Offer and the Merger. The Offer is not subject to any financing condition.

CA and Purchaser estimate that the total funds required to complete the Offer and the Merger and to pay related transaction fees and expenses will be approximately $548 million. CA intends to fund the tender offer using cash on hand, borrowings under its existing credit facility or access to capital markets. The offer is not subject to any financing conditions.

On November 26, 2014, a representative of Qatalyst Partners LP ("Qatalyst"), on behalf of CA, contacted Rally's Chief Executive Officer, Mr. Timothy Miller, in order to express CA's potential interest in engaging in strategic discussions with Rally. CA has been a customer and partner of Rally's offerings for approximately four years.

On November 29, 2014, Messrs. Timothy Miller, Rally's Chief Executive Officer, and Michael Gregoire, CA's Chief Executive Officer, spoke by telephone regarding CA's interest in a potential strategic transaction, as well as their views regarding the strategic plan of their respective companies and industry. Mr. Miller communicated that Rally was not currently in a position to proactively enter into strategic discussions at that time, but that he would review Mr. Gregoire's interest with the Rally Board and the Rally management team.

On December 3, 2014, a representative of Qatalyst telephoned Rally's Chief Financial Officer, Mr. James Lejeal, to discuss whether Rally was amenable to more detailed discussions among management teams, during which high-level operating and strategy due diligence information would be exchanged. Mr. Lejeal agreed to review the proposal for additional discussion with the Rally Board. In preparation for any such meeting, the parties agreed to have respective outside counsel review and negotiate an appropriate confidentiality agreement.

Between December 5, 2014 and December 9, 2014, representatives of Cooley LLP, outside counsel to Rally ("Cooley") and Wilson Sonsini Goodrich & Rosati, outside counsel to CA ("Wilson Sonsini"), negotiated the terms of a confidentiality agreement. During this period, and as instructed by the Rally Board, Rally's financial advisor, Deutsche Bank Securities Inc. ("Deutsche Bank"), contacted representatives of Qatalyst to discuss the general agenda, scope and expectations for Rally's and CA's upcoming meeting.

On December 9, 2014, CA and Rally executed a confidentiality agreement which included a customary standstill provision (and not a so-called "don't-ask-don't-waive" provision).

On December 10, 2014, representatives of CA, Rally, Qatalyst and Deutsche Bank, respectively, met for high-level diligence meetings to discuss Rally's historical financial performance, future outlook (as publicly disclosed) and high-level strategic plan. At the conclusion of the meeting, CA agreed to continue to review the information presented and contact Rally with any appropriate follow-up.

On December 21, 2014, representatives of CA and Rally, together with representatives of Qatalyst and Deutsche Bank, respectively, convened a telephonic meeting to provide and discuss the scope and substance of additional diligence requests.

On December 29, 2014, CA delivered orally and in writing a non-binding indication of interest to acquire Rally for $14.25 per Share in cash based upon public information and certain information provided by Rally. The letter indicated that CA anticipated conducting a thorough due diligence investigation and requested 45 days of exclusivity.

On December 30, 2014, on behalf of the Rally Board, Deutsche Bank communicated to Qatalyst the Rally Board's position that the CA proposal was inadequate from a financial perspective, but had also conveyed the Rally Board's willingness to remain open to any improved proposal that CA might consider in the future.

On January 12, 2015, following the Rally Board's rejection of CA's $14.25 per Share proposal, representatives of CA and Rally, together with Qatalyst and Deutsche Bank, respectively, met telephonically, at Qatalyst's request, to discuss the scope of additional diligence information that might inform CA's review of its previous proposal terms. The teams discussed CA's request to review information regarding Rally's 2016 fiscal year operating plan, Rally's long-term operating plan and outlook for its fourth quarter performance (based on analyst consensus estimates).

On January 13, 2015, in accordance with the directives of CA and Rally, representatives of Qatalyst and Deutsche Bank, respectively, met telephonically as a follow-up to their previous conversation on January 12^th to discuss and review the additional financial diligence information provided.

Also on January 16, 2015, CA delivered orally and in writing a non-binding indication of interest to acquire Rally for $14.75 per Share in cash based upon public information and the additional diligence information provided by Rally. The letter again indicated that CA anticipated conducting a thorough due diligence investigation and requested 45 days of exclusivity. Shortly thereafter, on behalf of the Rally Board, Deutsche Bank communicated to Qatalyst that the Rally Board again determined that the CA proposal was inadequate from a financial perspective, and that, based on the proposal, Rally was not interested in further discussions with CA, unless CA was willing to present a proposal more in line with Rally's historical value and anticipated future performance.

On April 2, 2015, Mr. Miller contacted Mr. Gregoire to discuss reengaging in potential strategic discussions and provide an update on Rally's upcoming first quarter of fiscal year 2016 and the product partnership between the companies. During the related discussion, Mr. Miller noted that a transaction price in the range of $19.00—$20.00 per Share would be more aligned with the Rally Board's valuation expectations if a transaction were to occur at this time. Mr. Gregoire agreed to review any additional discussion with the CA board of directors and management team.

On April 9, 2015, Mr. Gregoire contacted Mr. Miller to convey continuing interest in strategic discussions, commitment to the valuation range previously discussed (subject to confirmatory due diligence) and an expectation of delivering a formal written offer the following week.

On April 16, 2015, CA delivered orally and in writing a non-binding indication of interest to acquire Rally for $19.50 per Share in cash, which CA confirmed was its best and final offer. The letter again indicated that CA anticipated conducting a thorough due diligence investigation and requested 45 days of exclusivity.

From April 17 to April 19, 2015, Wilson Sonsini and Cooley exchanged drafts of a letter of intent and exclusivity agreement, which were executed on April 19^th with a 45-day exclusivity provision as requested by CA (and approved by the Rally Board) in connection with CA's full diligence review.

Over the course of the next several weeks, the parties and their respective advisors met in person and telephonically to provide and review business and legal due diligence, as well as to discuss a potential transaction timeline.

On May 3, 2015, Wilson Sonsini provided Cooley with a first draft of the proposed Acquisition Agreement to be negotiated concurrently with the completion of CA's due diligence. The Acquisition Agreement indicated that CA expected to enter into employment offer letters with certain members of Company management in connection with signing the Acquisition Agreement. As directed by the Rally Board, it was determined that any employment-related discussions would not begin until material terms of the Acquisition Agreement were finalized. On May 9, 2015, Cooley delivered a revised Acquisition Agreement to Wilson Sonsini, with material open points regarding tender offer conditions and the size of the proposed termination fee.

Over the course of the next two weeks, the parties and their respective advisors continued to review and finalize due diligence, resulting in no change to the CA offer of $19.50 per Share in cash. Wilson Sonsini and Cooley continued to negotiate and revise the Acquisition Agreement and related disclosure schedules, as well the Support Agreements requested by CA for execution by certain Company officers and directors.

On May 21, 2015, CA began engaging with certain members of Company management regarding employment offers to be executed in connection with signing the proposed Acquisition Agreement. Review and negotiation of these arrangements continued through May 27th.

On May 27, 2015, following a meeting of the Rally Board, Rally, CA and Purchaser executed the Acquisition Agreement on the terms approved by their respective boards of directors. The transaction was announced in a joint press release issued by Rally and CA following the close of the financial markets on May 27, 2015.

On May 27, 2015, the board of directors of CA convened, reviewed with management the terms of the transaction and approved the transaction.

With respect to any accrued but unused personal, sick or vacation time to which any U.S.-based Continuing Employee is entitled pursuant to the personal, sick or vacation policies applicable to such Continuing Employee immediately prior to the Effective Time, Rally will cash out all such vacation at the Merger Closing. With respect to any accrued but unused personal, sick or vacation time to which any Non-U.S.-based Continuing Employee is entitled pursuant to the personal, sick or vacation policies, laws or contracts applicable to such Non-U.S.-based Continuing Employee immediately prior to the Effective Time, CA will, or will cause the Surviving Corporation to and instruct its subsidiaries to, as applicable (and without duplication of benefits), assume the liability for such accrued personal, sick or vacation time and allow such Non-U.S.-based Continuing Employee to use such accrued personal, sick or vacation time in accordance with the practice and policies of CA and applicable laws and contracts.

CA will be solely responsible for all termination and severance benefits, costs, charges and liabilities of any nature incurred with respect to the termination of any Continuing Employees after the Effective Time, including any claims arising out of or relating to any mass layoff or similar event under applicable law occurring on or after the Effective Time.

CA agrees that all Continuing Employees will be eligible to continue to participate in the Surviving Corporation's health and welfare benefit plans.

Rally will terminate any and all 401(k) plans maintained by Rally or any ERISA Affiliates (as described below) (each, a "401(k) Plan"), in each case effective as of the day immediately preceding the date Rally becomes a member of the same controlled group of corporations (as defined in Section 414(b) of the Code) as CA (the "401(k) Termination Date"), unless CA provides prior written notice to CA that such 401(k) Plan(s) will not be terminated. Rally will provide CA evidence that the 401(k) plan(s) of Rally and its subsidiaries have been terminated pursuant to resolutions of the Rally Board or the board of directors of its subsidiaries, as applicable. Rally will also take such other actions

in furtherance of terminating any such 401(k) Plan(s) as CA may reasonably request. CA will use commercially reasonable efforts to allow the Continuing Employees to rollover any associated loan notes to the extent permitted under the 401(k) Plan. CA shall take all steps necessary to permit each such Continuing Employee who has received an eligible rollover distribution (as defined in Section 402(c)(4) of the Code) from Rally's 401(k) Plan to roll such eligible rollover distribution, including, for a reasonable period of time following the Effective Time, any associated loans into an account under a 401(k) plan maintained by CA or its subsidiaries to the extent permissible under such 401(k) plan, provided that CA shall undertake commercially reasonable efforts for a reasonable period of time following the Effective Time to amend the 401(k) plan maintained by CA to permit such rollover.

Rally will terminate any Stock Plans, group severance, separation, deferred compensation or salary continuation plans, programs or arrangements maintained by Rally or any of its ERISA Affiliates and other employee plans, in each case effective as of the day immediately preceding the last day of the initial period of the Offer.

As used herein, an "ERISA Affiliate" means each subsidiary of Rally and any other person or entity under common control with Rally or a subsidiary of Rally within the meaning of Section 414(b), (c), (m) or (o) of the Code.

In addition, except (i) as expressly contemplated or expressly permitted by the Acquisition Agreement, (ii) as set forth in Rally's confidential disclosure schedule to the Acquisition Agreement or (iii) as approved in advance by CA in writing (which approval will not be unreasonably withheld, delayed or conditioned with respect to (b) and (i) below), at all times during the period commencing with the execution and delivery of the Acquisition Agreement and continuing until the earlier to occur of (x) the Acceptance Time, (y) the Effective Time and (z) the termination of the Acquisition Agreement in accordance with its terms, Rally will not, and will cause its subsidiaries not to:

Nonsolicitation Obligation. Rally has agreed to immediately cease any and all existing activities, discussions or negotiations with any persons with respect to any offer, proposal or indication of interest relating to any Acquisition Transaction. Rally must promptly (and in any event within three business days following May 27, 2015) request in writing each person that has executed a confidentiality agreement in connection with its consideration of acquiring Rally or any portion thereof to return all confidential information furnished to such person by or on behalf of Rally, and Rally will use its reasonable best efforts to have such information returned or destroyed (to the extent destruction of such information is permitted by such confidentiality agreement). Such written notice will contain a notice to each person that any information that is sent in the future will not be treated as confidential pursuant to such confidentiality agreement.

Until the earlier to occur of the termination of the Acquisition Agreement and the Effective Time, Rally and its subsidiaries will not, and will use their reasonable best efforts to cause any of their respective directors, officers or other employees, controlled affiliates, or any investment banker, attorney or other advisors or representatives retained by any of them (collectively, the "Rally Representatives") not to (and will not authorize or permit any of them to), directly or indirectly,

(i) solicit, initiate, knowingly encourage, assist, facilitate or induce the making, submission or announcement of, an Acquisition Proposal (as described below) or Acquisition Transaction, (ii) except as expressly provided in the paragraph immediately below, participate or engage in discussions or negotiations with any person regarding an Acquisition Proposal or Acquisition Transaction, or furnish any non-public information relating to Rally or any of its subsidiaries, or afford access to the business, properties, assets, books or records of Rally or any of its subsidiaries to, or take any other action intended to encourage, assist or facilitate, any person that is seeking to make or has made an Acquisition Proposal, (iii) enter into any letter of intent, memorandum of understanding, definitive agreement or similar document or contract relating to any Acquisition Proposal or Acquisition Transaction, (iv) terminate, amend, waive or fail to enforce any rights under any "standstill" or other similar agreement between Rally or any of its subsidiaries and any person, or (v) waive the applicability of all or any portion of Section 203 of the DGCL in respect of any person (other than CA and its affiliates) in relation to any Acquisition Proposal or Acquisition Transaction.

Before the Acceptance Time, the Board of Directors of Rally may, directly or indirectly through advisors, agents or other intermediaries, subject to Rally's compliance with its nonsolicitation obligations, (A) engage or participate in discussions or negotiations with any person that has made (and not withdrawn) an unsolicited, bona fide, written Acquisition Proposal on or after May 27, 2015 that did not result from a breach of the Acquisition Agreement and that the Rally Board determines in good faith (after consultation with a financial advisor of nationally recognized standing and its outside legal counsel) is a Superior Proposal (as described below) or is reasonably likely to lead to a Superior Proposal and (B) furnish to any person that has made (and not withdrawn) an unsolicited, bona fide, written Acquisition Proposal on or after May 27, 2015 that did not result from a breach of the Acquisition Agreement and that the Rally Board determines in good faith (after consultation with a financial advisor of nationally recognized standing and its outside legal counsel) is a Superior Proposal or is reasonably likely to lead to a Superior Proposal any non-public information relating to Rally or any of its subsidiaries pursuant to a confidentiality agreement the terms of which are no less favorable to Rally than those contained in the confidentiality agreement by and between Rally and CA; provided, however, that in the case of any action taken pursuant to the foregoing clauses (A) or (B), (1) the Rally Board has determined in good faith (after consultation with outside legal counsel) that the failure to take such action is reasonably required to comply with its fiduciary duties to the stockholders of Rally under Delaware law, (2) at least forty-eight hours prior to taking any of the actions set forth in clauses (A) or (B), Rally gives CA written notice containing the information set forth in the paragraph immediately below, and of Rally's intention to take such actions and (3) contemporaneously with furnishing any non-public information to such person, Rally furnishes such non-public information to CA (to the extent not previously furnished). Any violation of Rally's nonsolicitation restrictions by any of Rally's directors, officers or other employees, controlled affiliates, or any investment banker, attorney or other advisors or representatives retained by any of them will constitute a breach of those restrictions by Rally.

In addition to Rally's nonsolicitation obligations, Rally must promptly, and in all cases within twenty-four (24) hours of its receipt, advise CA in writing of (i) any Acquisition Proposal, (ii) any request for information that would reasonably be expected to lead to an Acquisition Proposal or Acquisition Transaction or (iii) any inquiry with respect to, or which would reasonably be expected to lead to, any Acquisition Proposal or Acquisition Transaction, in each case, including the terms and conditions of such Acquisition Proposal or Acquisition Transaction, request or inquiry (unless such Acquisition Proposal is in written form, in which case Rally must give CA a copy thereof), and the identity of the person or group making any such Acquisition Proposal, request or inquiry. Rally must keep CA promptly and reasonably informed of the status, details, terms and conditions (including all amendments or proposed amendments) of any such Acquisition Proposal, request or inquiry. Rally must provide CA with at least forty-eight hours' prior written notice of a meeting of the Rally Board at which it is reasonably expected to consider an Acquisition Proposal or Acquisition Transaction, an

inquiry relating to a potential Acquisition Proposal or Acquisition Transaction, or a request to provide nonpublic information to any person in relation to an Acquisition Proposal or Acquisition Transaction.

Under the Acquisition Agreement, "Acquisition Proposal" means any offer, proposal or indication of interest (other than by CA or Purchaser or any designees of CA or Purchaser) relating to any Acquisition Transaction.

Under the Acquisition Agreement, "Acquisition Transaction" means any transaction or series of related transactions (other than the transactions contemplated by the Acquisition Agreement) involving: (i) any acquisition or purchase by any person or "group" (as defined in or under Section 13(d) of the Exchange Act), directly or indirectly, of more than a twenty percent (20%) interest in the total outstanding voting securities of Rally or one or more of its subsidiaries that own or control more than twenty percent (20%) of the consolidated assets (measured by the lesser of book or fair market value at the time of determination), revenues or earnings (measured as of the 12-month period immediately preceding the date of determination) of Rally and its subsidiaries, taken together as a whole, or any tender offer or exchange offer that if consummated would result in any person or "group" (as defined in or under Section 13(d) of the Exchange Act) beneficially owning more than twenty percent (20%) of the total outstanding voting securities of Rally or one or more of its subsidiaries that own or control more than twenty percent (20%) of the consolidated assets (measured by the lesser of book or fair market value at the time of determination), revenues or earnings (measured as of the 12-month period immediately preceding the date of determination) of Rally and its subsidiaries, taken together as a whole; (ii) any merger, consolidation, business combination or other similar transaction pursuant to which Rally stockholders immediately preceding such transaction hold, directly or indirectly, less than eighty percent (80%) of the equity interests in the surviving or resulting entity of such transaction; (iii) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition or disposition of more than twenty percent (20%) of the consolidated assets of Rally and its subsidiaries, taken together as a whole (measured by the lesser of book or fair market value thereof); (iv) any liquidation or dissolution of Rally or any of its subsidiaries or (v) any combination of the foregoing.

Under the Acquisition Agreement, "Superior Proposal" means any unsolicited, bona fide written offer or proposal to acquire 75% of the outstanding voting securities of Rally which Rally Board will have determined in good faith (after consultation with a financial advisor of nationally recognized standing and outside legal counsel, and after taking into account all aspects of such offer or proposal, including the identity of the third party making such offer or proposal, all financial, legal and regulatory aspects of such offer or proposal, the conditions to and prospects for completion of such offer or proposal and the transaction(s) contemplated thereby, as well as any counter-offer or proposal made by CA in response thereto) is more favorable to the Rally stockholders (in their capacity as such), from a financial point of view, than the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) and, if applicable, any counter-offer or proposal made by CA or any of its affiliates in response thereto.

Change in Board Recommendation. The Rally Board has unanimously (i) determined that the Acquisition Agreement is advisable, (ii) determined that the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, taken together, are at a price and on terms that are fair to, and in the best interests of Rally and its stockholders; (iii) approved the execution, delivery and performance by Rally of the Acquisition Agreement and the transactions contemplated thereby, including the Offer and the Merger, (iv) agreed that the Merger will be governed by Section 251(h) of the DGCL, and (v) resolved to recommend that Rally's stockholders tender their Shares to Purchaser pursuant to the Offer (the "Company Board Recommendation"). Neither the Rally Board nor any committee thereof will (A) fail to make, withhold, withdraw, amend, qualify or modify, or publicly propose to refuse to make, withhold, withdraw, amend, qualify or modify, the Company Board Recommendation, (B) approve, endorse or recommend an Acquisition Proposal,

or fail to publicly recommend against any such Acquisition Proposal that is a tender offer or exchange offer for Shares within ten business days after commencement of such offer (and at all times thereafter during which any such tender offer or exchange offer is pending) and reaffirm the Company Board Recommendation within such ten business day-period (and at all times thereafter during which any such tender offer or exchange offer is pending), (C) fail to include the Company Board Recommendation in the Schedule 14D-9, (D) fail to reaffirm the Company Board Recommendation within five Business days of a written request to do so by CA (which such request, in the case of an Acquisition Proposal which has not been made publicly known, CA will be limited to making no more than once every fifteen (15) days), or (E) resolve, agree or publicly propose to take any of the foregoing actions (any action described in the preceding clauses (A)—(E) being referred to collectively as a "Company Board Recommendation Change"); provided, however, that notwithstanding the foregoing, a "stop, look and listen" communication by the Rally Board pursuant to and in compliance with Rule 14d9-(f) of the Exchange Act will not be deemed to be a Company Board Recommendation Change and will not require compliance with the procedures set forth in this paragraph..

At any time prior to the Acceptance Time, the Rally Board may effect a Company Board Recommendation Change, if (A) the Rally Board has received an unsolicited, bona fide, written Acquisition Proposal and after consultation with a financial advisor of nationally recognized standing and outside legal counsel, the Rally Board will have determined, in good faith, that such Acquisition Proposal constitutes a Superior Proposal, (B) such Acquisition Proposal did not arise out of a breach of the provisions of the Acquisition Agreement, (C) the Board of Directors of rally has determined in good faith (after consultation with outside legal counsel and after considering in good faith any counter-offer or proposal made by CA pursuant to clause (E) below), that, in light of the foregoing Superior Proposal, the Rally Board is reasonably required to effect a Company Board Recommendation Change in order to comply with its fiduciary duties to the Rally stockholders under Delaware law, (D) prior to effecting such Company Board Recommendation Change, the Rally Board will have given CA at least four (4) business days prior written notice thereof (a "Determination Notice") (which Determination Notice will not constitute a Company Board Recommendation Change), which Determination Notice will attach such Superior Proposal and set forth the identity of the person making such Superior Proposal and all the material terms and conditions of such Superior Proposal in reasonable detail, and the opportunity to meet with the Rally Board and its outside legal counsel, all with the purpose and intent of enabling CA and Rally to discuss in good faith a modification of the terms and conditions of the Acquisition Agreement so that the transactions contemplated Thereby may be effected and (E) CA will not have made, within four business days after receipt of Rally's Determination Notice of its intention to effect a Company Board Recommendation Change, a counter-offer or proposal of a nature such that Rally Board will have determined in good faith (after consultation with a financial advisor of nationally recognized standing and its outside legal counsel) that the Acquisition Proposal no longer constitutes a Superior Proposal and after consultation with outside legal counsel the Rally Board is no longer reasonably required to effect a Company Board Recommendation Change in order to comply with its fiduciary duties to the Rally stockholders under Delaware law. Rally will keep confidential any such counter-offers or proposals made by CA to revise the terms of the Acquisition Agreement in accordance with its terms, other than in the event of any amendment to the Acquisition Agreement and to the extent required to be disclosed in any SEC Reports. The provisions of this paragraph also apply to any material amendment to any Acquisition Proposal and require a new Determination Notice, except that the references to four business days will be deemed to be two business days.

At any time prior to the Acceptance Time, the Rally Board may effect a Company Board Recommendation Change in response to an Intervening Event if (A) the Rally Board will have determined in good faith (after consultation with outside legal counsel) that, in light of such Intervening Event, the Rally Board is reasonably required to effect a Company Board Recommendation Change in order to comply with its fiduciary duties to Rally stockholders under Delaware law, (B) prior

to effecting such Company Board Recommendation Change, the Rally Board will have given CA a Determination Notice at least four business days prior written notice thereof, which Determination Notice will specify in reasonable detail the facts underlying the determination that an Intervening Event has occurred and the rationale and basis for such Company Board Recommendation Change and the opportunity to meet with the Rally Board and its outside legal counsel, all with the purpose and intent of enabling CA and Rally to discuss in good faith a modification of the terms and conditions of the Acquisition Agreement so as to obviate the need to effect a Company Board Recommendation Change on the basis of such Intervening Event so that the transactions contemplated thereby may be effected, and (C) following the expiration of such four-business day period, the Rally Board will have determined in good faith (after consultation with outside legal counsel) and after giving good faith consideration to any offer or proposal from CA, that, in light of such Intervening Event, the Rally Board is reasonably required to effect a Company Board Recommendation Change in order to comply with its fiduciary duties to the Rally stockholders under Delaware law.

Under the Acquisition Agreement, "Intervening Event" means, with respect to Rally, a material fact, event, change, development or set of circumstances (other than, and not arising out of or resulting from, an Acquisition Proposal) that (i) was neither known to nor reasonably foreseeable by any member of the Rally Board, assuming reasonable consultation with the executive officers of Rally, as of or prior to May 27, 2015, (ii) did not result from or arise out of the reasonably foreseeable consequences of the announcement or pendency of, or any actions required to be taken (or to be refrained from being taken) pursuant to, the Acquisition Agreement, and (iii) does not relate to, result from or arise out of any Acquisition Proposal (whether or not a Superior Proposal) May 27, 2015.

Director and Officer Indemnification and Insurance. After the Effective Time, CA must cause the Surviving Corporation and its subsidiaries to honor and fulfill Rally's and its subsidiaries' obligations under their respective certificates of incorporation and bylaws (and other similar organizational documents) and all indemnification agreements in effect as of May 27, 2015 between Rally or any of its subsidiaries and any of their respective current or former directors and officers (the "Company Indemnified Parties") May 27, 2015.

For six years after the Effective Time, CA and the Surviving Corporation will maintain Rally's current directors' and officers' liability insurance ("D&O Insurance") in respect of acts or omissions occurring at or prior to the Acceptance Time, covering each person covered by the D&O Insurance as of May 27, 2015, on terms with respect to the coverage and amounts no less favorable, in the aggregate, than those of the D&O Insurance in effect on May 27, 2015; provided, however, that the Surviving Corporation may, at its option, substitute policies containing terms with respect to coverage and amounts no less favorable, in the aggregate, to such persons than the D&O Insurance. CA and the Surviving Corporation will not be obligated to pay annual premiums in excess of two hundred percent (200%) of the amount paid by Rally for coverage for its last full fiscal year (such two hundred percent (200%) amount, the "Maximum Annual Premium"), except that if the annual premiums of such insurance coverage exceed that amount, CA and the Surviving Corporation will be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Before the Acceptance Time, CA may purchase a six-year "tail" prepaid policy (the "Tail Policy") on the D&O Insurance on terms and conditions no less favorable, in the aggregate, than the D&O Insurance. If CA purchases a Tail Policy before the Acceptance Time, CA and the Surviving Corporation will maintain the Tail Policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of the obligations under the first sentence of this paragraph for so long as such Tail Policy is maintained.

If CA or the Surviving Corporation or any of its successors or assigns consolidate with or merge into any other person and are not the continuing or surviving corporation or entity of such consolidation or merger or transfer all or substantially all of its properties and assets to any person, then proper provisions will be made so that the successors and assigns of CA and the Surviving

Corporation will assume all of the obligations of CA and Rally in this section titled "Director and Officer Indemnification and Insurance".

The obligations in this section titled "Director and Officer Indemnification and Insurance" will not be terminated, amended or otherwise modified in a manner as to adversely affect any Company Indemnified Party without the prior written consent of such person.

Termination Prior to Acceptance Time. The Acquisition Agreement and the Offer can be terminated and abandoned prior to the Acceptance Time only as follows:

Under the terms of the Acquisition Agreement, "Parent Material Adverse Effect" means any fact, event, circumstance, change or effect that, individually or when taken together with all other such facts, events, circumstances, changes or effects, would reasonably be expected to materially impede the ability of CA or Purchaser to consummate the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) in accordance with the terms of the Acquisition Agreement and applicable law.

Under the terms of the Acquisition Agreement, "Company Material Adverse Effect" means any fact, event, circumstance, change or effect that, individually or when taken together with all other such facts, events, circumstances, changes or effects, has been or would reasonably be expected to (x) be materially adverse to the business, operations, properties, assets (including intangible assets), liabilities, condition (financial or otherwise) or results of operations of Rally and its subsidiaries, taken together as a whole or (y) materially impede the ability of Rally or its subsidiaries to consummate the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger) in

accordance with the terms of the Acquisition Agreement and applicable law; provided, however, that none of the following facts, events, circumstances, changes or effects, by itself or when aggregated with any one or more of the other such facts, events, circumstances, changes or effects, will be deemed to be or constitute a Company Material Adverse Effect and none of the following facts, events, circumstances, changes or effects, by itself or when aggregated with any one or more of the other such facts, events, circumstances, changes or effects, will be taken into account when determining whether a Company Material Adverse Effect has occurred or would reasonably be expected to occur:

Effect of Termination. If the Acquisition Agreement is terminated it will be of no further force or effect without liability of any party or parties thereto to the other party or parties thereto, except (i) the notice obligations of the Acquisition Agreement, Rally's obligations with respect to the payment of the Termination Fee Amount, and certain general provisions of the Acquisition Agreement, each of which will survive the termination of the Acquisition Agreement, and (ii) that nothing will relieve any party or parties thereto from liability for any willful or intentional breach of, or fraud in connection with, the Acquisition Agreement.

Termination Fees. If (i) following the execution and delivery of the Acquisition Agreement and before the termination thereof, an Acquisition Proposal has been publicly announced or become publicly known, or will have been communicated or otherwise made known to Rally, and (ii) the

Acquisition Agreement is thereafter terminated pursuant to the second or third bullet of the section titled "Termination Prior to Acceptance Time", and (iii) within twelve months following the termination of the Acquisition Agreement, either an Acquisition Transaction (whether or not the Acquisition Transaction referenced in the preceding clause (i)) is consummated or Rally enters into a letter of intent, memorandum of understanding or other contract providing for an Acquisition Transaction (whether or not the Acquisition Transaction referenced in the preceding clause (i)), then Rally will pay CA (or its designee), within one business days after the event in the preceding clause (iii) that triggers the obligation to pay such fee, a fee in the amount of $17.4 million (the "Termination Fee Amount") payable in cash by wire transfer of immediately available funds to an account designated in writing by CA (provided that for purposes of this paragraph, the references to "20%" and "80%" in the definition of "Acquisition Transaction" will be deemed to be references to "50%"). If (i) following the execution and delivery of the Acquisition Agreement and prior to the breach described in clause (ii) below that forms the basis for the termination of the Acquisition Agreement, an Acquisition Proposal will have been publicly announced or will have become publicly known, or will have been communicated or otherwise made known to Rally and (ii) the Acquisition Agreement is thereafter terminated pursuant to section (i) of the fifth bullet of the section titled "Termination Prior to Acceptance Time" (solely where the underlying breach of the covenant or agreement by Rally was intentional) and (iii) within twelve months following the termination of the Acquisition Agreement, either an Acquisition Transaction (whether or not the Acquisition Transaction referenced in the preceding clause (i)) is consummated or Rally enters into a letter of intent, memorandum of understanding or other contract providing for an Acquisition Transaction (whether or not the Acquisition Transaction referenced in the preceding clause (i)), then Rally will pay to CA (or its designee), within one business day after the event in the preceding clause (iii) that triggers the obligation to such fee, the Termination Fee Amount in cash by wire transfer of immediately available funds to an account designated in writing by CA (provided that for purposes of this paragraph the references to "20%" and "80%" in the definition of "Acquisition Transaction" will be deemed to be references to "50%").

If the Acquisition Agreement is terminated pursuant to the seventh bullet of the section titled "Termination Prior to Acceptance Time", Rally will pay to CA (or its designee), within one business day after such termination, the Termination Fee Amount in cash by wire transfer of immediately available funds to an account designated in writing by CA.

If the Acquisition Agreement is terminated pursuant to the eight bullet of the section titled "Termination Prior to Acceptance Time", Rally will pay to CA (or its designee), contemporaneously with such termination, the Termination Fee Amount in cash by wire transfer of immediately available funds to an account designated in writing by CA.

If Rally fails to pay the Termination Fee Amount in a timely manner and, in order to obtain such payment, CA makes a claim that results in a judgment against Rally, Rally must promptly reimburse CA its reasonable costs and expenses (including its reasonable attorneys' fees and expenses) incurred in connection with such suit, together with interest on the Termination Fee Amount at the prime rate of Citibank N.A. in effect on the date such payment was required to be made. Payment of Termination Fee Amount is not in lieu of, or replacement or substitution for, damages incurred in the event of any breach of the Acquisition Agreement.

The following directors and named executive officers of Rally, as owners of the Shares and Shares issuable upon exercise of outstanding options, restricted stock units and warrants, as applicable, next to their names below, entered into Support Agreements with CA (the "Support Agreements") that, among other things (i) restrict the transfer of their Shares; (ii) obligate each of them to grant an irrevocable

proxy to CA to vote their respective Shares in favor of the adoption of the Acquisition Agreement and any other matter necessary for consummation of the transactions contemplated by the Acquisition Agreement and/or against any action or agreement which would in any material respect impede, interfere with or prevent the Offer or the Merger, including, but not limited to, any (a) Acquisition Proposal, (b) reorganization, recapitalization, dissolution, liquidation or winding-up of Rally or any other extraordinary transaction involving Rally other than the Merger, (c) action, proposal, transaction or agreement that would reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of such individual under his or her respective Support Agreement, or (d) corporate action or agreement, the consummation of which, or proposal, the approval of which, would reasonably be expected to prevent or materially delay the consummation of any of the transactions contemplated by the Acquisition Agreement, including the Offer and the Merger; and (iii) obligate each of them to tender all their respective Shares in the Offer not later than the fifth business day after commencement of the Offer (or if such individual has not received the Offer Documents by such time, within two business days following receipt of such documents) and no later than the third business day after such individual acquires beneficial ownership of any additional Shares.

Based on the number of Shares outstanding as of May 27, 2015, the number of Shares beneficially owned by the stockholders that entered into the Support Agreements and eligible to be tendered in the Offer represent approximately 5.9% of Rally's issued and outstanding common stock. This summary is qualified in its entirety by reference to the Form of Support Agreement, which is filed as Exhibit (a)(2)(B) to this Schedule TO and is incorporated by reference herein.

On December 9, 2014, Rally and CA entered into the Confidentiality Agreement in order to facilitate the consideration and negotiation of a possible negotiated transaction involving the parties and/or their affiliates. Under the Confidentiality Agreement, Rally and CA agreed, subject to certain exceptions, (i) not to make use of or disclose to any other person any of the other party's confidential information; (ii) to certain employee non-solicitation provisions for a period of twelve months commencing on the date of the Confidentiality Agreement; and (iii) to certain standstill provisions during the twelve month period commencing on the date of the Confidentiality Agreement.

The foregoing summaries of the Confidentiality Agreement do not purport to be complete and are qualified in their entirety by reference to the Confidentiality Agreement, a copy of which is filed as Exhibit (d)(2) to the Schedule TO filed with the SEC, which is incorporated herein by reference.

Concurrent with the execution of the Merger Agreement, CA entered into new offer letters and employment and confidentiality agreements (each offer letter and the corresponding employment and confidentiality agreement, an "Executive Offer Letter") with certain individuals, including each of Rally's executive officers. Each such Executive Offer Letter shall be effective as of the Merger Closing Date. The Executive Offer Letters provide for, among other things, certain retention bonuses and severance benefits in the event of involuntary terminations of employment. If the severance payments and benefits or any other payments or benefits provided for a CA employee constitute "excess parachute payments" within the meaning of Section 280G of the Code, then those payments and benefits will either be (x) delivered in full (to the extent due) to the employee or (y) reduced to the minimum extent necessary so that the employee will receive the greatest economic benefit on an after-tax basis, notwithstanding that all or some portion of the payments and benefits may be subject to an excise tax under Sections 280G and 4999 of the Code.

A more complete description of the Executive Offer Letters is included in Rally's Schedule 14D-9, which will be filed with the SEC and is being mailed to Rally's stockholders with this Offer to Purchase.

Purpose of the Offer. The purpose of the Offer is for CA to acquire control of, and all of the equity interests in, Rally. The Offer, as the first step in the acquisition of Rally, is intended to facilitate the acquisition of all of the outstanding Shares. The purpose of the Merger is to acquire all of the outstanding Shares not tendered and purchased pursuant to the Offer. The Merger Closing will take place promptly after the consummation of the Offer.

If you sell your Shares in the Offer, you will cease to have any equity interest in Rally or any right to participate in its earnings and future growth. If you do not tender your Shares, but the Merger is consummated, you also will no longer have an equity interest in Rally. Similarly, after selling your Shares in the Offer or the subsequent Merger, you will not bear the risk of any decrease in the value of Rally.

Merger Without a Meeting. If the conditions to the Offer are satisfied and the Offer is consummated, we will not seek the approval of Rally's remaining public stockholders before effecting the Merger. Section 251(h) of the DGCL provides that following consummation of a successful tender offer for a public corporation, and subject to certain statutory provisions, if the acquirer holds at least the amount of shares of each class of stock of the target corporation that would otherwise be required to approve a merger for the target corporation, and the other stockholders receive the same consideration for their stock in the merger as was payable in the tender offer, then the acquirer can effect a merger without the action of the non-tendering stockholders of the target corporation. With respect to a tender offer, Section 251(h) of the DGCL provides that the word "consummate" (and with correlative meaning, "consummation" and "consummating") means the irrevocable acceptance for purchase of shares tendered pursuant to a tender offer. Therefore, references to a consummation of the Offer herein refer to the occurrence of the Acceptance Time. Accordingly, if we consummate the Offer, we intend to effect the Merger Closing without a vote of the stockholders of Rally pursuant to and in accordance with Section 251(h) of the DGCL.

Plans for Rally. It is expected that, initially following the Merger, the business and operations of Rally will, except as set forth in this Offer to Purchase, be continued substantially as they are currently being conducted. In connection with or following the Merger Closing, CA may consolidate or reorganize certain corporate entities in Rally's structure, but CA has no present plans or proposals to sell or transfer any such entities or change the business or operations of Rally as a result of such consolidation or corporate reorganization. CA will continue to evaluate the business and operations of Rally during the pendency of the Offer and after the consummation of the Offer and the Merger and will take such actions as it deems appropriate under the circumstances then existing. Thereafter, CA intends to review such information as part of a comprehensive review of Rally's business, operations, capitalization and management with a view to optimizing development of Rally's potential.

As set forth in this in this Offer to Purchase, including Section 11—"The Acquisition Agreement; Other Agreements", and the Schedule 14D-9, certain members of Rally's current management team have entered into new employment arrangements with CA, which will not become effective until the consummation of the Offer, if at all. To the best knowledge of Purchaser and CA, other than the foregoing and as otherwise disclosed in this Offer to Purchase (including the Support Agreements described in Section 8—"Certain Information Concerning Parent and Purchaser"), no employment, equity contribution, or other agreement, arrangement or understanding between any executive officer or director of Rally, on the one hand, and CA, Purchaser, or Rally, on the other hand, existed as of May 27, 2015, and neither the Offer nor the Merger is conditioned upon any executive officer or director of Rally entering into any such agreement, arrangement or understanding.

At the Effective Time, (a) the certificate of incorporation of Rally be amended and restated in its entirety to read identically to the certificate of incorporation of Purchaser, as in effect immediately prior to the Effective Time, and such amended and restated Certificate of Incorporation will become the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with the applicable provisions of Delaware law and such certificate of incorporation; provided, however, that at the Effective Time the certificate of incorporation of the Surviving Corporation will be amended so that the name of the Surviving Corporation will be "Rally Software Development Corp." and (b) the bylaws of Purchaser, as in effect immediately prior to the Effective Time, will become the bylaws of the Surviving Corporation until thereafter amended in accordance with the applicable provisions of Delaware law, the certificate of incorporation of the Surviving Corporation and such bylaws. At the Effective Time, (a) the members of the board of directors of Purchaser immediately prior to the Effective Time will become the initial directors of the Surviving Corporation and (b) the officers of Purchaser immediately prior to the Effective Time will become the initial officers of the Surviving Corporation, in each case to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors have been duly elected, appointed or qualified.

Except as set forth in this Offer to Purchase, including as contemplated in this Section 12—"Purpose of the Offer; Plans for Rally—Plans for Rally", CA and Purchaser have no present plans or proposals that would relate to or result in (i) any extraordinary corporate transaction involving Rally or any of its subsidiaries (such as a merger, liquidation, relocation of any operations or sale or other transfer of a material amount of assets), (ii) any sale or transfer of a material amount of assets of Rally or any of its subsidiaries, (iii) any material change in Rally's capitalization or dividend policy, or (iv) any other material change in Rally's corporate structure or business or composition of its management or board of directors.

Market for the Shares. If the conditions to the Offer are satisfied and the Offer is consummated, there will be no market for the Shares because CA intends to consummate the Merger immediately following the Acceptance Time.

Stock Quotation. The Shares are currently listed on the NYSE. Immediately following the Effective Time, the Shares will no longer meet the requirements for continued listing on the NYSE because the only stockholder will be CA. The NYSE requires, among other things, that any listed shares of common stock have at least 600,000 publicly held shares. Immediately following the consummation of the Merger, CA intends and will cause Rally to delist the Shares from the NYSE.

Margin Regulations. The Shares are currently "margin securities" under the Regulations of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board"), which has the effect, among other things, of allowing brokers to extend credit on the collateral of such Shares. Immediately following the consummation of the Offer, the Shares would no longer constitute "margin securities" for the purposes of the margin regulations of the Federal Reserve Board and, therefore, could no longer be used as collateral for loans made by brokers.

Exchange Act Registration. The Shares are currently registered under the Exchange Act. Such registration may be terminated upon application of Rally to the SEC if the Shares are neither listed on a national securities exchange nor held by 300 or more holders of record. Termination of registration of the Shares under the Exchange Act would substantially reduce the information required to be furnished by Rally to its stockholders and to the SEC and would make certain provisions of the Exchange Act no longer applicable to Rally, such as the short-swing profit recovery provisions of Section 16(b) of the Exchange Act, the requirement of furnishing a proxy statement pursuant to Section 14(a) of the Exchange Act in connection with stockholders' meetings and the related requirement of furnishing an

annual report to stockholders and the requirements of Rule 13e-3 under the Exchange Act with respect to "going private" transactions. Furthermore, the ability of "affiliates" of Rally and persons holding "restricted securities" of Rally to dispose of such securities pursuant to Rule 144 promulgated under the Securities Act may be impaired or eliminated. If registration of the Shares under the Exchange Act were terminated, the shares would no longer be "margin securities" or be eligible for listing on the NYSE. We intend and will cause Rally to terminate the registration of the Shares under the Exchange Act as soon after consummation of the Offer as the requirements for termination of registration are met and, in any event, following the consummation of the Merger.

The Acquisition Agreement provides that from May 27, 2015 to until the earlier to occur of (x) the Acceptance Time, (y) the Effective Time and (z) the termination of the Acquisition Agreement pursuant in accordance with its terms, unless expressly permitted by the Acquisition Agreement, set forth in a confidential disclosure schedule to the Acquisition Agreement or approved in advance in writing by CA, other than cash dividends made by any direct or indirect wholly-owned subsidiary of Rally to Rally or one of its subsidiaries, Rally will not, and will cause its subsidiaries not to, split, combine or reclassify any shares of capital stock, declare, set aside or pay any dividend or other distribution (whether in cash, shares or property or any combination thereof) in respect of any shares of capital stock, or make any other actual, constructive or deemed distribution in respect of the shares of capital stock.

Notwithstanding any other term of the Offer or the Acquisition Agreement, Purchaser is not required to, and CA is not required to cause Purchaser to, accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) promulgated under the Exchange Act (relating to Purchaser's obligation to pay for or return tendered Shares of Rally promptly after the termination or withdrawal of the Offer), pay for any Shares that are validly tendered in the Offer and not withdrawn prior to the Expiration Date unless, at or prior to the Expiration Date:

On June 5, 2015, the United States Federal Trade Commission terminated early the waiting period applicable to the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger).

As used herein, a "Fundamental Representations" means the representations and warranties of Rally with respect to organization and good standing, authorization and enforceability, absence of certain changes and Company Material Adverse Effect, and brokers.

As used herein, a "Capitalization Representation" means the representations and warranties of Rally with respect to capitalization.

CA and Purchaser may increase the Offer Price or otherwise amend, modify, or make changes to the terms and conditions of the Offer; provided, however, that unless otherwise provided by the Acquisition Agreement or previously approved by Rally in writing, neither CA nor Purchaser may make any change to the terms and conditions of the Offer that:

General. Except as described in this Section 16, including HSR approval, based on our examination of publicly available information filed by Rally with the SEC and other information concerning Rally, we are not aware of any governmental license or regulatory permit that appears to be material to Rally's business that might be adversely affected by our acquisition of Shares as contemplated herein or of any approval or other action by any governmental, administrative or regulatory authority or agency, domestic or foreign, that would be required for the acquisition or ownership of Shares by Purchaser or CA as contemplated herein. Should any such approval or other action be required, we currently contemplate that, except as described below under "State Takeover Laws", such approval or other action will be sought. While we do not currently intend to delay acceptance for payment of Shares tendered pursuant to the Offer pending the outcome of any such matter, there can be no assurance that any such approval or other action, if needed, would be obtained or would be obtained without substantial conditions or that if such approvals were not obtained or such other actions were not taken, adverse consequences might not result to Rally's business, any of which under certain conditions specified in the Acquisition Agreement could cause us to elect to terminate the Offer without the purchase of Shares thereunder under certain conditions. See Section 15—"Certain Conditions to the Offer".

Antitrust Compliance. Under the HSR Act, and the related rules and regulations that have been issued by the United States Federal Trade Commission (the "FTC"), certain transactions may not be consummated unless specified information and documentary material (including the "Premerger Notification and Report Forms") have been furnished to the FTC and the Antitrust Division of the Department of Justice (the "Antitrust Division") and certain waiting period requirements have been satisfied. These requirements of the HSR Act apply to the acquisition of Shares in the Offer and the Merger.

Under the HSR Act, the purchase of Shares in the Offer may not be completed until the expiration of a fifteen calendar day waiting period following the filing by CA of a Premerger Notification and Report Form concerning the Offer with the FTC and the Antitrust Division, unless the waiting period is earlier terminated by the FTC and the Antitrust Division.

CA and Rally filed their Premerger Notification and Report Forms on May 28, 2015 with the FTC and the Antitrust Division in connection with the purchase of Shares in the Offer and the Merger. On June 5, 2015, the United States Federal Trade Commission terminated early the waiting period applicable to the transactions contemplated by the Acquisition Agreement (including the Offer and the Merger).

The FTC and the Antitrust Division may scrutinize the legality under the antitrust laws of Purchaser's proposed acquisition of Rally Shares pursuant to the Offer. At any time before or after Purchaser's acceptance for payment of Shares pursuant to the Offer, if the Antitrust Division or the FTC believes that the Offer would violate the U.S. federal antitrust laws by substantially lessening competition in any line of commerce affecting U.S. consumers, the FTC and the Antitrust Division have the authority to challenge the transaction by seeking a federal court order enjoining the transaction or, if Shares have already been acquired, requiring disposition of such Shares, or the divestiture of substantial assets of Purchaser, Rally, or any of their respective subsidiaries or affiliates, or requiring other conduct relief. United States state attorneys general and private persons may also bring legal action under the antitrust laws seeking similar relief or seeking conditions to the completion of the Offer. While CA believes that consummation of the Offer would not violate any antitrust laws, there can be no assurance that a challenge to the Offer on antitrust grounds will not be made or, if a challenge is made, what the result will be. If any such action is threatened or commenced by the FTC, the Antitrust Division or any state or any other person, Purchaser may not be obligated to consummate the Offer or the Merger. See Section 15—"Certain Conditions to the Offer."

State Takeover Laws. A number of states (including Delaware, where Rally is incorporated) have adopted takeover laws and regulations which purport, to varying degrees, to be applicable to attempts to acquire securities of corporations that are incorporated in such states or that have substantial assets, stockholders, principal executive offices or principal places of business, or whose business operations otherwise have substantial economic effects therein.

In general, Section 203 of the DGCL prevents a Delaware corporation from engaging in a "business combination" (defined to include mergers and certain other actions) with an "interested stockholder" (including a person who owns or has the right to acquire 15% or more of a corporation's outstanding voting stock) for a period of three years following the time such person became an "interested stockholder" unless, among other things, the "business combination" is approved by the board of directors of such corporation before such person became an "interested stockholder." The Rally Board has approved the Acquisition Agreement and the transactions contemplated thereby, including the Offer, and the Merger, for purposes of Section 203 of the DGCL.

Based on information supplied by Rally and the approval of the Acquisition Agreement and the transactions contemplated by the Acquisition Agreement by the Rally Board, we do not believe that any other state takeover statutes or similar laws purport to apply to the Offer or the Merger. Except as described herein, neither CA nor Rally has currently attempted to comply with any state takeover statute or regulation. We reserve the right to challenge the applicability or validity of any state law purportedly applicable to the Offer or the Merger and nothing in this Offer to Purchase or any action taken in connection with the Offer or the Merger is intended as a waiver of such right. If it is asserted that any state takeover statute is applicable to the Offer or the Merger and an appropriate court does not determine that it is inapplicable or invalid as applied to the Offer or the Merger, we might be required to file certain information with, or to receive approvals from, the relevant state authorities, and we might be unable to accept for payment or pay for Shares tendered pursuant to the Offer, or be delayed in consummating the Offer or the Merger. In such case, we may not be obligated to accept payment or pay for any Shares tendered pursuant to the Offer. See Section 15—"Certain Conditions to the Offer" of this Offer to Purchase.

Stockholders do not have appraisal rights as a result of the Offer. However, if the Merger is consummated, all Shares that are issued and outstanding immediately prior to the Effective Time and held by stockholders who have properly and validly exercised their statutory rights of appraisal in respect of such Shares in accordance with Section 262 of the DGCL (collectively, "Dissenting Company Shares") will not be converted into, or represent the right to receive, the Merger Consideration, but will be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Company Shares. At the Effective Time, the Dissenting Company Shares will no longer be outstanding and will automatically be cancelled and cease to exist, and each Rally stockholder who holds Dissenting Company Shares will cease to have any rights with respect to such Dissenting Company Shares, except the right to receive payment of the appraised value of such Dissenting Company Shares in accordance with the provisions of Section 262 of the DGCL. Each holder of Dissenting Company Shares will be entitled to receive a judicial determination of the fair value of such Dissenting Company Shares (exclusive of any element of value arising from the accomplishment or expectation of the merger or similar business combination), and to receive payment of such fair value in cash, together with a fair rate of interest, if any, of such Dissenting Company Shares. Any such judicial determination could be based upon considerations other than, or in addition to, the price paid in the Offer and the market value of such Dissenting Company Shares. Rally stockholders should recognize that the judicially-determined fair value could be higher or lower than the Offer Price. Moreover, Rally may argue in an appraisal proceeding that, for purposes of such a proceeding, the fair value of the Dissenting Company Shares is less than the price paid for Shares in the Offer or the Merger. Rally stockholders should also

note that investment banking opinions as to the fairness, from a financial point of view, of the consideration payable in a sale transaction, such as the Offer or the Merger, are not opinions as to, and do not otherwise address, fair value under Section 262 of the DGCL.

If any holder of Shares who demands appraisal under Section 262 of the DGCL fails to perfect, or effectively withdraws or loses his, her or its rights to appraisal as provided under the DGCL, or a court of competent jurisdiction determines that such holder is not entitled to the relief provided by Section 262 of the DGCL, then the Shares of such Rally stockholder will be converted into the right to receive the Merger Consideration (which will be the same as the Offer Price), without interest thereon, in accordance with the Acquisition Agreement.

A stockholder may, within sixty days after the Effective Time of the Merger, withdraw a demand for appraisal by delivering to Rally a written withdrawal of the demand for appraisal and accept the terms offered pursuant to the Merger Agreement. Failure to follow the steps required by Section 262 of the DGCL for perfecting appraisal rights may result in the loss of such rights.

The foregoing summary of the rights of stockholders seeking appraisal under Delaware law does not purport to be a complete statement of the procedures to be followed by stockholders desiring to exercise any appraisal rights available thereunder and is qualified in its entirety by reference to Section 262 of the DGCL. The foregoing does not constitute the notice of appraisal rights and related disclosure required by Section 262 of the DGCL. That notice and disclosure will be included in Rally's Appraisal Rights Statement on Schedule 14D-9.

The perfection of appraisal rights requires strict adherence to the applicable provisions of the DGCL. If a stockholder withdraws or loses the right to appraisal, such stockholder will be entitled to receive only the Merger Consideration.
