It is important that you vote every GOLD card you receive.

How to Vote the Gold Card Vote Online Vote By Phone Vote By Mail How to vote GOLD To vote for Pershing Square’s Nominees for ADP’s Transformation, vote the GOLD Proxy Card or GOLD Voting Instruction Form. Based on your account holdings, you will receive similar material from ADP that will say “White Proxy Card” or “White Voting Instruction Form.” PLEASE DISCARD ANY MATERIALS YOU RECEIVE FROM ADP.

Voting FAQ Proxy and Voting Information When Should Shareholders Receive Their Proxy Materials? Shareholders should start receiving the Proxy Materials, including the GOLD Proxy Card or GOLD Voting Instruction Form, the week of September 25th. How Do I Vote By Proxy? You can vote online, by mail or by phone. See the “How To Vote” section of this website. When Is The Cut-Off For Voting My Proxy? If you hold your shares through a bank or brokerage firm, the voting cut-off for Internet or telephone voting is 11:59 PM on November 6, 2017. If you hold your shares in registered form (not through a bank or brokerage firm), the voting cut-off for Internet and telephone voting is at 8:30 am on November 7, 2017 (the start of the Annual Meeting). Why Have I Received More Than One Proxy Card? You will receive multiple GOLD Proxy Cards or GOLD Voting Instruction Forms for each account that holds shares of ADP. It is very important to submit a vote for each account in which you hold shares via the GOLD Proxy Cards or GOLD Voting Instruction Forms and discard any white proxy cards or white voting instruction forms you receive from ADP. Should I Vote Again When I Get Duplicate Mailings? Yes, you should vote each and every GOLD Proxy Card or GOLD Voting Instruction Form, for every account holding ADP shares. What Happens if I Voted the White Proxy Card and Then Want to Change my Vote to Vote for Pershing Square’s Nominees for ADP’s Transformation? Only your latest dated proxy will count. If you previously voted via a white proxy card or white voting instruction form, you can revoke it by subsequently voting a later dated GOLD Proxy Card or GOLD Voting Instruction Form. I Have Multiple Gold And White Cards. What Should I Do? Vote each GOLD Proxy Card or GOLD Voting Instruction Form you receive to support Pershing Square’s Nominees for ADP’s Transformation. You should discard all white cards you receive from ADP. What Should I Do With The White Proxy Card? You should discard all white proxy cards or white voting instruction forms you receive from ADP. How Did Pershing Square Get My Name And Address? ADP turned over its shareholder lists to Pershing Square as required by state law. Can A Vote Be Changed Or Revoked After A Proxy Card Is Returned? Yes, if you previously returned a white card or white voting instruction form, you can revoke it by subsequently voting a later dated and signed GOLD Proxy Card or GOLD Voting Instruction Form. Voting via the white proxy card will revoke any vote you previously made via the GOLD Proxy Card or GOLD Voting Instruction Form. Accordingly, you should not vote any white proxy cards or white voting instruction forms. Only your most recent vote will count at the annual meeting. Can I Vote In Person At The Annual Meeting Instead Of Voting By Proxy? Yes. If you hold your shares in registered form (not through a bank or brokerage firm), you can vote by ballot at the annual meeting. If you hold your shares through a bank or brokerage firm, you must obtain a “legal proxy” from your bank or brokerage firm to enable you to vote at the annual meeting. However, we encourage you to vote your GOLD proxy by Internet, telephone, or mail prior to the meeting, even if you plan to attend in person. Will My Control Number Be The Same For All Of My Accounts? No. You will have a different control number for each account that holds ADP shares. Will The Control Number Be The Same For ADP’s and Pershing Square’s Materials? No. Each account that holds ADP shares will have separate control numbers for the proxy materials sent to you by Pershing Square (GOLD proxy card control number) versus proxy materials sent to you by ADP (white proxy card control number). Am I a “Registered Shareholder” or a “Beneficial Shareholder”? What’s the difference? You’re a registered shareholder if you own ADP shares in your own name (not through a bank or brokerage firm). You’re a beneficial shareholder if you own the shares through a bank or brokerage firm. Registered shareholders should vote the GOLD Proxy Card. Beneficial shareholders should vote on the GOLD Voting Instruction Form. What Should I Do If I’m Not Sure if I Have Received the Right Voting Forms?

ADP Ascending HOME HOW TO VOTE THE NOMINEES INVESTOR RELATIONS REACTIONS CONTACT REACTIONS “[ADP’s] rebuttal was, in our view, a confident, well-articulated, detailed, reiteration of the status quo for ADP, providing plenty of insightful incremental data points and disclosures, but no material change to the financial outlook for the company. ADP established three-year guidance for the first time, but the guidance was consistent with its already-disseminated FY18 guidance and long-term business model.” Lisa Ellis, Bernstein (Sep 13, 2017) “We continue to view Pershing’s activism as a net win for the company longer term.” Tien-Tsin Huang, J.P. Morgan (Sep 7, 2017) “ADP gross margins are noticeably lower than peer PAYX and the software providers despite the company’s significant scale. In addition, despite the comparison issues such as inclusion of pass through revenues, greater international exposure (higher growth/lower margins), and revenue mix, we believe the company has significant opportunity to expand margins… we agree that there are significant margin expansion opportunities and expect the activist involvement to potentially help drive greater focus on improving the Employer Services margins going forward.” Bryan Keane, Deutsche Bank (Sep 5, 2017) “We believe there is likely a valid case for accelerated margin expansion at ADP, and there is merit in Pershing challenging the rate and pace at which ADP is driving efficiency in service delivery and addressing its legacy platforms. There is a 10-15ppt delta between ADP and competitor margins which cannot be easily explained by structural differences, ADP’s business is more labor-intensive than peers, and examples exist (e.g., CDK) of successful margin expansion after spinning out of ADP.” Lisa Ellis, Bernstein (Aug 31, 2017) “We agreed with many of the points highlighted by Pershing… There is an opportunity to further improve margins. ADP’s revenue/employee lags competitors reflecting multiple platforms and redundant service centers.” Mark Marcon, Baird (Aug 18, 2017) “Pershing clearly did its homework and scored some important points. After listening in, our sense is there is an above consensus opportunity to boost profitability.We were expecting a much more detailed rebuttal from the company yesterday. Instead, all we got was a claim that Pershing’s presentation ‘betrays a fundamental lack of understanding of the current state of ADP’s business.’ To that, we’d say that at this point, no investor, no analyst, NO ADVISOR, and probably few board members know more about problems in the company than Pershing Square.” Don Bilson and Eric Wiley, Gordon Haskett (Aug 18, 2017) “[Pershing Square] did break out a number of analytically sound points that can add up to a sizeable benefit. We particularly liked the points on the level of support (vs. service); product sprawl; siloed / unnecessarily complex organization and duplication. Our own checks suggest this may be true… ADP has been managed for risk-averse multi-year gain, it is appropriate to ask these tough questions and expect an answer on the likelihood of setting an aggressive target and trying to deliver on it.” Ashwin Shirvaikar, Citi (Aug 17, 2017) “We agree with Pershing’s longer-term goals; we suspect management and the board will as well. … The notion of consolidating the Enterprise segment onto the mid-market platform is perhaps our most significant incremental takeaway. This could substantially simplify ADP’s operating model and increase scale efficiencies if it can be executed.” David Grossman and Craig Jones, Stifel (Aug 17, 2017) “This is similar to Pershing Square’s investment in Canadian Pacific, a company that was near its all-time high when Pershing Square filed its 13D with a thesis of margin improvement. Canadian Pacific also had excuses for its margins (i.e., bad weather) but Pershing Square ultimately implemented its plan and doubled the profit margins, leading to a 153.3% return on its investment. Similarly, Pershing Square was instrumental in improving margins at Air Products by 50% in three years.” 13 D Monitor (Aug 7, 2017) “Why is there such a long period before the shareholder meeting for director nominations Does Pershing Square maybe have a leg to stand on “Rodriguez needs to acknowledge that while no one likes to face the fact that they can be replaced, a CEO must always realize that they serve at the pleasure of the Board and the shareholders of the company. All shareholders deserve respect and acknowledgement. It’s the job of the CEO not only to sell their vision of the company to clients but also to shareholders – even the hostile shareholders. “No CEO, Chairman or Board member should ever forget that their true boss is the shareholder.”– Egan-Jones Proxy Services | August 14th, 2017 Sign up for email updates: EMAIL* SUBMIT Contacts Pershing Square Fran McGill 212 909 2455 McGill@persq.com Rubenstein Steve Murray 212 843 8293 smurray@rubenstein.com Eric Kuo 212 843 8494 ekuo@rubenstein.com Note: Due to copyright protection we are not able to provide analyst and other reports in their entirety.
