Dear Fellow CPA®:17 – Global Stockholder, The Boards of Directors of Corporate Property Associates 17 – Global Inc. (“CPA®:17 – Global”) and W. P. Carey Inc. have approved a proposal to combine the two companies in a merger. We believe this transaction will be beneficial to you as a CPA®:17 – Global stockholder by providing you with liquid shares of W. P. Carey (NYSE: WPC), a leading publicly traded net lease real estate investment trust (“REIT”) that is positioned for continued stable dividends and growth. We are proposing to combine CPA®:17 – Global and W. P. Carey because we believe that the the merger will offer: As a CPA®:17 – Global stockholder, you will receive 0.160 shares of W. P. Carey common stock for each share of CPA®:17 – Global stock owned. Based on the range of W. P. Carey’s stock closing prices during the period from June 15, 2018 (the last trading day prior to the announcement of the merger) through August 22, 2018, this implies a per share merger consideration value ranging from a low of $10.34 to a high of $10.87. This represents a premium of 3% to 8%, respectively, to CPA®:17 – Global’s estimated net asset value (“NAV”) per share of $10.04 as of December 31, 2017. Because the exchange is based on a fixed ratio, the ultimate consideration received by CPA®:17 – Global investors may be higher or lower as W. P. Carey’s stock price changes. As a result of the merger, CPA®:17 – Global investors will hold shares of W. P. Carey, CPA®:17 – Global’s advisor since inception. Founded 45 years ago, W. P. Carey has been publicly traded since 1998 and a REIT since 2012, providing attractive returns to its investors for more than four decades and increasing its dividend every year since going public twenty years ago. W. P. Carey ranks among the largest and foremost net lease REITs. Following the merger, W. P. Carey will have a pro forma total enterprise value of approximately $17 billion and a diversified portfolio of more than 131 million square feet of income-generating corporate real estate leased to 302 tenant companies. The com-bined company is expected to have even greater financial strength and flexibility given its larger balance sheet and diversified portfolio. • • Liquidity for CPA®:17 – Global stockholders The opportunity for CPA®:17 – Global stockholders to continue their investment in a similar company, on a tax-deferred basis, receiving income in the form of quarterly dividends and participating in the potential upside of a publicly traded REIT A high-quality portfolio of premium net lease assets diversified across industries, geographies and property types with limited integration risk Significant scale, with a pro forma enterprise value of $16.7 billion A combined company poised for growth with the potential to drive shareholder value by enhancing revenue, credit profile and portfolio composition • • • W.

CPA®:17 – Global’s Reasons for the Merger with W. P. Carey and the Charter Amendment include: The Potential Negative Factors and Risks of the Merger with W. P. Carey and the Charter Amendment include: • the merger provides liquidity to CPA®:17 – Global’s stockholders by delivering to them shares in a publicly traded company with a broad stockholder base, and with no lock-ups or other restrictions on transfer; based on the range of W. P. Carey’s closing stock prices during the period from June 15, 2018 (the last trading day prior to the announcement of the merger) through August 22, 2018, the exchange ratio represents a per share merger consideration value ranging from a low of $10.34 to a high of $10.87, implying a premium of 3% to 8%, respectively, to CPA®:17 – Global’s estimated NAV of $10.04 per share as of December 31, 2017; the dividend that CPA®:17 – Global stockholders will receive based on the exchange ratio and W. P. Carey’s existing dividend rate will increase slightly and the improved payout ratio will result in dividends of a higher quality, which may lead to greater divi-dend growth over time; as a result of its larger size and enhanced balance sheet, the combined company is expected to have greater operating and financial flexibility and better access to capital markets with a lower cost of capital than CPA®:17 – Global on a standalone basis; and the Charter Amendment will permit the merger to occur without having to comply with the procedural and substantive require-ments of the CPA®:17 – Global Charter applicable to ‘‘Roll-Up Transactions,’’ which the CPA®:17 – Global Board of Directors and the CPA®:17 – Global Special Committee believe are impractical. • the average lease maturity of the combined company’s portfolio will be approximately 10.4 years, which is lower than CPA®:17 – Global’s current average lease maturity of 11.5 years and may increase risks related to re-leasing or dispositions; the challenges inherent in the combination of two business enterprises that are the size of CPA®:17 – Global and W. P. Carey and the risks and costs to CPA®:17 – Global if the merger does not close; the possibility that the transaction with W. P. Carey will not be completed or may be delayed, and the possible adverse effects on the future liquidity options for CPA®:17 – Global that might result if the proposed transaction with W. P. Carey were announced and not completed; the risk that a different liquidity alternative or a decision not to enter into a current liquidity transaction could ultimately have been more beneficial to CPA®:17 – Global stockholders than the proposed transaction with W. P. Carey; and if the CPA®:17 – Global stockholders approve the Charter Amendment, the consummation of the merger will be excluded from the procedural and substantive provisions of the CPA®:17 – Global Charter applicable to “Roll-Up Transactions.” • • • • • • • • CPA®:17 – Global Has Generated Strong Returns for Investors 1 Reflects distributions declared through June 2018.
