Upon request by the Seller, Purchaser shall document and confirm such position to the Seller.

6

Section 5.4 Indemnification.

(a) Indemnification by the Purchaser. If the Purchaser breaches any of the covenants set forth in Section 5.3 and, solely as a result of such breach, the Seller is required to pay, and does in fact pay, Swiss federal corporate income taxes arising out of the Repurchase Transaction and/or out of the transfer of 37,050,000 shares of Common Stock of the Purchaser to BigPoint Holding AG, the private holding company of Mr. Haefner, which, for the avoidance of doubt, shall be reduced by any deduction, loss, credit or other tax attribute that may be utilized to reduce such corporate income taxes, then the Purchaser shall pay to the Seller an amount such that, taking into account reasonable expenses incurred by the Seller with respect to such breach and the Swiss federal corporate income taxes (including interest and penalties) imposed on the Seller as the result of the payment received from the Purchaser pursuant to this Section 5.4(a), the Seller is in the same after-tax position in which the Seller would have been in the absence of the Purchaser’s breach of such covenants; provided that the Seller shall, at the Purchaser’s request, contest any imposition of such Swiss federal corporate income taxes in good faith to the fullest extent permitted by applicable law and; provided, further, that the Purchaser shall not be obligated to make any payment under this Section 5.4(a) until a final tax bill or decision, which can no longer be legally contested, will have been rendered, confirming that Swiss federal corporate income taxes arising out of the Repurchase Transaction and/or out of the transfer of the 37,050,000 shares of Common Stock of the Purchaser to BigPoint Holding AG are due, except that, if Seller has made a good faith determination that Purchaser is likely to have an obligation to make a payment under this Section 5.4(a), Purchaser shall advance to the Seller the amount of any tax payment or deposit of tax reasonably required to contest any imposition of such Swiss federal corporate income taxes, provided that any refund of such tax payment or deposit of tax shall be for the account of the Purchaser. The Purchaser will in any event not be liable for any consequential, incidental or indirect damages suffered by the Seller as a result of the Purchaser’s breach of such covenants. The Seller shall promptly notify the Purchaser in writing upon receipt of notice of any tax audits, examinations or assessments that could give rise to a liability for which the Purchaser may be responsible under this Section 5.4(a). The Seller shall also (i) notify the Purchaser of significant developments with respect to such tax audit, examination or assessment, (ii) give to the Purchaser a copy of any tax adjustment proposed in writing with respect to such tax audit, examination or proceeding and copies of any other written correspondence with the relevant taxing authority related to such tax audit, examination or proceeding, (iii) not settle or compromise any issue without the consent of the Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed, (iv) otherwise permit the Purchaser to participate in all aspects of such tax audit, examination or proceeding (including, but not limited to, appeal proceeding) at the Purchaser’s own expense. A certificate delivered by the Seller to the Purchaser after such payment of Swiss federal corporate income taxes shall, absent manifest error, be conclusive as to the amount owed by the Purchaser to the Seller. The Purchaser shall make a payment in cash to the Seller in the amount presented in such certificate within ten (10) business days of the receipt of such certificate. The Parties agree that, from and after the Closing, the remedies provided for in this Section 5.4(a) shall constitute the sole and exclusive remedy for any and all loss or damage that the Seller may suffer or incur arising from, or directly or indirectly relating to, a breach by the Purchaser of such covenants.

7

(b) Indemnification by the Seller. If the United States Internal Revenue Service (“IRS”) asserts that the deduction or withholding of taxes was required by applicable law with respect to the payment of the Purchase Price made by the Purchaser to the Seller pursuant to this Agreement, the Seller shall pay to the Purchaser an amount such that, taking into account reasonable expenses incurred by the Purchaser with respect to any such assertion and all taxes (including interest and penalties) imposed on the Purchaser as the result of the payment received from the Seller pursuant to this Section 5.4(b), the Purchaser is in the same after-tax position in which the Purchaser would have been if the IRS had not asserted that any deduction or withholding of taxes was so required; provided that the Purchaser shall, at the Seller’s request, contest any such assertion in good faith to the fullest extent permitted by applicable law and; provided, further, that the Seller shall not be obligated to make any payment under this Section 5.4(b) until there has been a final “determination” within the meaning of Section 1313(a) of the United States Internal Revenue Code of 1986, as amended, as to the amount of tax, if any, that is due by reason of the failure to so deduct or withhold, except that, if Purchaser has made a good faith determination that Seller is likely to have an obligation to make a payment under this Section 5.4(b), the Seller shall advance to the Purchaser the amount of any tax payment or deposit of tax reasonably required to contest any such assertion, provided that any refund of such tax payment or deposit of tax shall be for the account of the Seller. The Seller will in any event not be liable for any consequential, incidental or indirect damages suffered by the Purchaser as a result of the IRS’s assertion that any deduction or withholding of taxes was required. The Purchaser shall promptly notify the Seller in writing upon receipt of notice of any tax audits, examinations or assessments that could give rise to a liability for which the Seller may be responsible under this Section 5.4(b). The Purchaser shall also (i) notify the Seller of significant developments with respect to such tax audit, examination or assessment, (ii) give to the Seller a copy of any tax adjustment proposed in writing with respect to such tax audit, examination or proceeding and copies of any other written correspondence with the relevant taxing authority related to such tax audit, examination or proceeding, (iii) not settle or compromise any issue without the consent of the Seller, which consent shall not be unreasonably withheld, conditioned or delayed, (iv) otherwise permit the Seller to participate in all aspects of such tax audit, examination or proceeding at the Seller’s own expense. A certificate delivered by the Purchaser to the Seller after a final determination shall, absent manifest error, be conclusive as to the amount owed by the Seller to the Purchaser. The Seller shall make a payment in cash to the Purchaser in the amount presented in such certificate within ten (10) business days of the receipt of such certificate. The Parties agree that, from and after the Closing, the remedies provided for in this Section 5.4(b) shall constitute the sole and exclusive remedy for any and all loss or damage that the Purchaser may suffer or incur arising from, or directly or indirectly relating to, the IRS’s assertion that any deduction or withholding of taxes was required by applicable law with respect to the payment of the Purchase Price made by the Purchaser to the Seller pursuant to this Agreement.

Section 5.5 Survival. Section 5.3, Section 5.4 and this Section 5.5 shall survive the Closing.

Section 5.6 Tax Treatment. The Parties agree to treat any indemnity payment under Section 5.4 as an adjustment to the Purchase Price, which interpretation shall be followed for United States federal income tax and Swiss tax purposes to the fullest extent permitted by applicable law.

CA Technologies Increases Dividend, Accelerates Stock Repurchase Program, and Announces Additional $750M Stock Repurchase Authorization

NEW YORK, November 18, 2015 — CA Technologies (NASDAQ: CA) announced today that it intends to increase the dividend per share in Fiscal Year 2017, subject to quarterly board approval, to $1.02 per share for the year, or $0.255 per share on a quarterly basis. This is up from the current $1.00 per share annual dividend, or $0.25 per share on a quarterly basis.

The company has accelerated its Common Stock Repurchase Program, having agreed to repurchase 22 million shares of its Common Stock from Careal Holding AG, its largest shareholder, in a private transaction valued at $590 million (with an effective share repurchase price of $26.81 per share).

The per share purchase price represents a 3% discount to the 10-trading day volume weighted average price for CA stock using a reference date of November 5, 2015. The closing price of CA stock on November 17, 2015 was $26.90. The transaction, which is expected to close in the third quarter of Fiscal Year 2016, will be funded from US cash on hand.

Careal Holding AG has disclosed that Martin Haefner, one of Careal’s co-principals, will obtain approximately 37 million shares of CA common stock from Careal to add to his personal investment holdings.

This deal effectively concludes CA’s prior $1 billion stock repurchase program, through which CA had repurchased approximately 11 million shares as of September 30, 2015. As a result, as part of the company’s capital allocation strategy, CA’s board of directors has authorized a new $750 million share repurchase program.

The impact of the accelerated share repurchase is expected to benefit GAAP EPS by $0.03 and non-GAAP EPS by $0.04 in FY16.

“Our capital allocation strategy, which includes a new $750 million share buy-back authorization as well as an increasing dividend, reflects our improved confidence in our business as we look to the coming years,” said Rich Beckert, CFO, CA Technologies. “The transaction with Careal provided us with the opportunity to accelerate our share repurchase program at favorable prices, and highlights our long-term strategy of returning capital to shareholders.”

Careal used CA’s share buyback program as an opportunity to rebalance Careal’s assets as part of an overall reallocation. Careal issued a statement today that “Careal Holding AG and its shareholders remain the principal shareholders of CA Technologies… they believe that CA Technologies will continue to grow and intend to keep hold of their investments for the long term.”

Non-GAAP Financial Measures

This news release includes certain financial measures that exclude the impact of certain items and therefore have not been calculated in accordance with U.S. generally accepted accounting principles (GAAP). Non-GAAP metrics for diluted earnings per share exclude the following items: share-based compensation expense; non-cash amortization of purchased software and other intangible assets; charges relating to rebalancing initiatives that are large enough to require approval from the Company’s Board of Directors, and certain other gains and losses. The Company began expensing costs for internally developed software where development efforts commenced in the first quarter of fiscal 2014. Due to this change, the Company also adds back capitalized internal software costs and excludes amortization of internally developed software costs previously capitalized from these non-GAAP metrics. These non-GAAP financial measures may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. By excluding these items, non-GAAP financial measures facilitate management’s internal comparisons to the Company’s historical operating results and cash flows, to competitors’ operating results and cash flows, and to estimates made by securities analysts. Management uses these non-GAAP financial measures internally to evaluate its performance and they are key variables in determining management incentive compensation. The Company believes these non-GAAP financial measures are useful to investors in allowing for greater transparency of supplemental information used by management in its financial and operational decision-making. In addition, the Company has historically reported similar non-GAAP financial measures to its investors and believes that the inclusion of comparative numbers provides consistency in its financial reporting.

Cautionary Statement Regarding Forward-Looking Statements

The declaration and payment of future dividends is subject to the determination of the Company’s Board of Directors, in its sole discretion, after considering various factors, including the Company’s financial condition, historical and forecast operating results, and available cash flow, as well as any applicable laws and contractual covenants and any other relevant factors. The Company’s practice regarding payment of dividends may be modified at any time and from time to time.

Repurchases under the Company’s stock repurchase program may be made from time to time, subject to market conditions and other factors, in the open market, through solicited or unsolicited privately negotiated transactions or otherwise. The program does not obligate the Company to acquire any particular amount of common stock, and it may be modified or suspended at any time at the Company’s discretion. Certain statements in this communication (such as statements containing the words “believes,” “plans,” “anticipates,” “expects,” “estimates,” “targets” and similar expressions relating to the future) constitute “forward-looking statements” that are based upon the beliefs of, and assumptions made by, the Company’s management, as well as information currently available to management. These forward-looking statements reflect the Company’s current views with respect to future events and are subject to certain risks, uncertainties, and assumptions. A number of important factors could cause actual results or events to differ materially from those indicated by such forward-looking statements, including: the ability to achieve success in the Company’s strategy by, among other things, enabling the Company’s sales force to accelerate growth of new product sales (at levels sufficient to offset any decline in revenue in the Company’s Mainframe Solutions segment), improving the Company’s brand, technology and innovation awareness in the marketplace, ensuring the Company’s offerings for cloud computing, application development and IT operations (DevOps), Software-as-a-Service (SaaS), and mobile device management, as well as other new offerings, address the needs of a rapidly changing market, while not adversely affecting the demand for the Company’s traditional products or its profitability to an extent greater than anticipated, and effectively managing the strategic shift in the Company’s business model to develop more easily installed software, provide additional SaaS offerings and refocus the Company’s professional services and education engagements on those engagements that are connected to new product sales, without affecting the Company’s performance to an extent greater than anticipated; the failure to innovate or adapt to technological changes and introduce new software products and services in a timely manner; competition in product and service offerings and pricing; the ability of the Company’s products to remain compatible with ever-changing operating environments, platforms or third party products; global economic factors or political events beyond the Company’s control and other business and legal risks associated with non-U.S. operations; the failure to expand partner programs; the ability to retain and attract qualified professionals; general economic conditions and credit constraints, or unfavorable economic conditions in a particular region, industry or business sector; the ability to successfully integrate acquired companies and products into the Company’s existing business; risks associated with sales to government customers; breaches of the Company’s data center, network, as well as the Company’s software products, and the IT environments of the Company’s vendors and customers; the ability to adequately manage, evolve and protect the Company’s information systems, infrastructure and processes; fluctuations in foreign exchange rates; discovery of errors or omissions in the Company’s software products or documentation and potential product liability claims; the failure to protect the Company’s intellectual property rights and source code; the failure to renew large license transactions on a satisfactory basis; access to software licensed from third parties; risks associated with the use of software from open source code sources; third-party claims of intellectual property infringement or royalty payments; fluctuations in the number, terms and duration of the Company’s license agreements, as well as the timing of orders from customers and channel partners; events or circumstances that would require the Company to record an impairment charge relating to the Company’s goodwill or capitalized software and other intangible assets balances; potential tax liabilities; changes in market conditions or the Company’s credit ratings; the failure to effectively execute the Company’s workforce reductions, workforce rebalancing and facilities consolidations; successful and secure outsourcing of various functions to third parties; changes in generally accepted accounting principles; and other factors described more fully in the Company’s filings with the Securities and Exchange Commission. Should one or more of these risks or uncertainties occur, or should the Company’s assumptions prove incorrect, actual results may vary materially from those described herein as believed, planned, anticipated, expected, estimated, targeted or similarly expressed in a forward-looking manner.
