Macerich Company_left_Nov06.wmfMACERICH History of Strong Corporate Governance 7 Macerich stands out among REIT peers as having a long history of strong, stockholder-friendly governance .Single class of common stock (one share / one vote) .Commitment to declassified Board1 .Majority voting for directors with director resignation policy .Right to call special meeting .Strong Lead Independent Director role .All committees consist 100% of independent directors .Annual evaluations of individual directors and committees .Limit to number of other boards directors can serve on .Regular succession planning and proactive board refreshment practices .Comprehensive risk oversight .Robust Code of Ethics for directors and senior management .Focus on corporate social responsibility Key Governance Practices (1): Macerich implemented an annually elected board in 2008; in response to the SPG proposal, a classified board was adoptedfor a limited duration, and Macerich has committed to declassify the Board no later than immediately after the 2016 Annual Meeting

Macerich Company_left_Nov06.wmfMACERICH Overview of the Board’s Response to Simon’s Interest 8 .Macerich received an unsolicited acquisition proposal from Simon Property Group on March 9, 2015 –SPG’s proposal included a partnership between SPG (the #1 mall owner by assets) and General Growth Partners (#2), with an agreement for SPG to sell selected Macerich assets to GGP –SPG’s “best and final” proposal 3 weeks later represented less than a 5% increase over the March 9, 2015 offer .In evaluating the proposal, the Board considered factors including the following: –The proposal substantially undervalued the company and, while it would have benefited SPG (who established a position in Macerich's stock prior to bidding) and investors with short-term horizons, it was not in the best interests of our long-term stockholders –Macerich’s portfolio, which contains many trophy assets that rarely become available for sale and cannot be replicated –Macerich’s strategic plan and current management team’s track record of successful execution –Macerich’s development and redevelopment plans over the next 5 to 10 years, which are expected to be high return-on-cost projects and materially enhance long-term stockholder value –The structure, timing and circumstances of SPG’s proposals, which reduced the potential for competitive offers –The implications of SPG’s stock as consideration, including the dual-class nature and lack of transparent disclosures .The Board’s process for evaluating the proposal was robust –Highly independent Board consisting of real estate and financial experts, assisted by independent financial advisors and counsel –Board includes significant investor perspectives, including a representative of one of Macerich’s largest current stockholders and our Lead Independent Director, Fred Hubbell, is the former Chairman, Insurance and Asset Management Americas for ING Group –Board met eight times over several months in connection with SPG’s interest, including executive sessions of solely independent directors led by our Lead Independent Director

Macerich Company_left_Nov06.wmfMACERICH Macerich is Responsive to Stockholder Feedback 9 Macerich has engaged with investors holding more than 50%of shares to facilitate an open dialogue In response to the unique circumstances surrounding SPG’s proposal, Macerich’s Board took actions including: .Unanimously rejecting the SPG proposal as not in the best interests of stockholders .Adopting temporary governance changes to provide sufficient time for Macerich and its long-term stockholders to evaluate SPG's proposal and for Macerich to pursue a full range of alternatives should SPG have subsequently submitted a proposal that did not significantly undervalue Macerich –Macerich has committed to reverse these changes –Terminated stockholder rights plan as of May 7, 2015 –Committed to declassify Board no later than immediately after the 2016 Annual Meeting .Providing stockholders with enhanced disclosure regarding Macerich’s robust development pipeline and shadow pipeline Board considers key decisions with stockholders’ interest at front of mind With a focus on maintaining a balance of perspectives and experiences on the Board level, we added two new independent director nominees: .Added John Alschuler –Chairman of HR&A Advisors, Inc., an economic development, real-estate and public policy consulting organization .Added Steven Hash –President and COO of Renaissance Macro Research and Former Head of Real Estate Investment Banking at Barclays .Two current directors will retire and not stand for reelection at this year’s Annual Meeting New directors increase overall Board independence and decrease average tenure
