Dear Exxon Mobil Shareowner:

Support Proposal #4 and #9 Requesting an Independent Board Chair and Improved Disclosure of Lobbying Activities

---

CalPERS is the largest state public pension fund in the United States with nearly $400 billion¹ in total assets under management, and a long-term owner of approximately ten million shares in Exxon Mobil Corp. We encourage shareowners to vote FOR proposal #4 and #9 at the company’s May 27^th, 2020 annual meeting of shareowners.

Please note that proposal #4 was filed by The Olga Monks Pertzoff Trust 1945 as lead proponent of a filing group, and proposal #9 was filed by The United Steelworkers.

Vote FOR Proposal #4 Requesting an Independent Board Chair

---

CalPERS believes that investors will benefit if the board is chaired by an independent director who can provide a balance of power between the CEO and the board, and support effective board oversight of management. In our view, appointing a board chair who is independent of management is nearly always preferable to having one individual lead both the board and the management team.

Leading corporate governance investor organizations like the Counsel of Institutional Investors and the International Corporate Governance Network also agree. While we recognize that Exxon Mobil has appointed a lead independent director, in our view, an independent board chair is better positioned to oversee the executives of the company and represent shareowners without the inherent conflicts that a CEO or other executive insiders will encounter.

Vote FOR Proposal #9 Requesting Improved Disclosure of Lobbying Activities

---

We believe that shareowners would benefit from improved disclosure of the company's political spending activities and lobbying expenditures. In our view, improved disclosure would allow shareowners to better assess the risks and benefits associated with such spending.

---

¹CalPERS total assets under management at year end December 31, 2019.

Vote FOR Proposal #4 and #9

---

As a significant investor in Exxon Mobil, we encourage shareowners to support proposal #4 and #9. We believe that an independent chair structure will lead to a more proactive, responsive, and effective board of directors. We also believe that improved disclosure of the company's political spending activities and lobbying expenditures would allow shareowners to better assess the risks and benefits associated with such spending.
