Item 4.

Purpose of Transaction

Item 4 of Schedule 13D is supplemented and superseded, as the case may be, as follows:

Closing of Merger

On November 5, 2019, Taylor Morrison Home Corporation (“Taylor Morrison”), and Tower Merger Sub, Inc., a wholly owned, direct subsidiary of Taylor Morrison (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with William Lyon Homes (the “Issuer”), pursuant to which Merger Sub will be merged with and into the Issuer (the “Merger”), with the Issuer continuing as the surviving entity in the Merger as a wholly owned, direct subsidiary of Taylor Morrison. On February 6, 2020, the Merger closed.

At the effective time of the Merger (the “Effective Time”), each issued and outstanding share of Class A Common Stock of the Issuer, and each issued and outstanding share of Class B Common Stock of the Issuer (together, the “Common Shares”), (excluding any shares (i) that are restricted Common Shares; (ii) held by any stockholder who properly demands and perfects his, her or its appraisal rights with respect to such shares; or (iii) owned directly by the Issuer (or any wholly owned subsidiary of the Issuer, Taylor Morrison or Merger Sub immediately prior to the Effective Time) was converted into the right to receive and became exchangeable for (A) 0.8000 validly issued, fully paid and nonassessable shares of common stock, $0.00001 par value per share, of Taylor Morrison (“Taylor Morrison Shares”) and (B) $2.50 in cash, without any interest thereon. No fractional Taylor Morrison Shares were issued in the Merger, and Issuer stockholders received cash in lieu of any fractional shares. All Common Shares of the Issuer beneficially owned by the Reporting Persons were converted at the Effective Time pursuant to the Merger as described in this paragraph, including 234,217 shares of Class A Common Stock directly held by William H. Lyon, 2,933 shares of Class A Common Stock directly held by the Lyon Separate Property Trust, and 4,817,394 shares of Class B Common Stock directly held by the Lyon Investor.

At the Effective Time, each outstanding and unexercised stock option (each, an “Option”), whether vested or unvested, exercisable or not exercisable, of the Issuer was substituted and converted by Taylor Morrison granting an option (each, a “Taylor Morrison Option”) in substitution of such Option, to purchase a number of whole Taylor Morrison Shares (rounded down to the nearest whole share) equal to the product obtained by multiplying (i) the number of Common Shares subject to such Option immediately prior to the Effective Time by (ii) the sum (the “Equity Award Exchange Ratio”) of (x) 0.8000 and (y) the quotient obtained by dividing $2.50 by the volume weighted average per-share price of Taylor Morrison Shares during the ten full trading days ending on (and including) the trading day immediately preceding the Effective Time. The exercise price per share of such Taylor Morrison Option (rounded up to the nearest cent) is equal to the quotient obtained by dividing (i) the exercise price per Common Share of such Option immediately prior to the Effective Time by (ii) the Equity Award Exchange Ratio. Following the Effective Time, such Taylor Morrison Options are subject to the same vesting and acceleration of vesting terms and conditions as, and have other terms and conditions that are substantially similar to, those that applied to the Options immediately prior to the Effective Time. The options to purchase 120,000 Class A shares of the Issuer held directly by William H. Lyon were substituted and converted at the Effective Time pursuant to the Merger as described in this paragraph.

In addition, at the Effective Time, (i) each outstanding award of restricted Common Shares (each, a “Restricted Stock Award”) and (ii) each outstanding performance stock unit award in respect of Common Shares (each, a “PSU Award”) were substituted and converted by Taylor Morrison granting in substitution a corresponding award in respect of Taylor Morrison Shares (each, a “Taylor Morrison Award”), with the number of whole Taylor Morrison Shares underlying each such Taylor Morrison Award equal to (rounded down to the nearest whole share) the product obtained by multiplying (i) the number of Common Shares underlying such Restricted Stock Award or PSU Award, as applicable, immediately prior to the Effective Time (assuming that any performance-based vesting conditions applicable to such Restricted Stock Award or PSU Award, as applicable, for any performance period that has not been completed as of the Effective Time are achieved at target) by (ii) the Equity Award Exchange Ratio. Following the Effective Time, such Taylor Morrison Awards are subject to the same vesting and acceleration of vesting terms and conditions (other than any performance-based vesting conditions) as, and have other terms and conditions that are substantially similar to, those that applied to the corresponding Restricted Stock Award or PSU Award, as applicable, immediately prior to the Effective Time. The 55,345 Restricted Stock Awards and the 29,446 PSU Awards held directly by William H. Lyon were substituted and converted at the Effective Time pursuant to the Merger as described in this paragraph.

Further, at the Effective Time, the Class B Warrant held by Lyon Investor was substituted and converted by Taylor Morrison issuing a warrant (the “Taylor Morrison Warrant”) to be settled in Taylor Morrison Shares in substitution of the Class B Warrant exercisable for a number of whole Taylor Morrison Shares (rounded down to the nearest whole share) equal to the product obtained by multiplying (i) the number of Common Shares subject to the Class B Warrant immediately prior to the Effective Time by (ii) the Equity Award Exchange Ratio. The exercise price per share of the Taylor Morrison Warrant (rounded up to the nearest cent) will be equal to the quotient obtained by dividing (i) the exercise price per share of Class B Common Stock of the Class B Warrant immediately prior to the Effective Time by (ii) the Equity Award Exchange Ratio. Following the Effective Time, the Taylor Morrison Warrant is subject to substantially identical terms to those of the Class B Warrant immediately prior to the Effective Time, except that the Taylor Morrison Warrant will be exercisable on a net exercise basis.

At the Effective Time, William H. Lyon resigned from the Board of Directors of the Issuer.
