On August 4, 2015, RSP Permian, Inc., a Delaware corporation (the “Company”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with Goldman, Sachs & Co. (the “Underwriter”) relating to the offer and sale (the “Offering”) of 7,000,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), by the Company at a price to the public of $22.50 per share ($22.19 per share net of underwriting discounts and commissions). Pursuant to the Underwriting Agreement, the Company has granted the Underwriter a 30-day option to purchase up to an additional 1,050,000 shares of Common Stock.

The Underwriting Agreement contains customary representations and warranties, agreements and obligations, closing conditions and termination provisions. The Company has agreed to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments the Underwriter may be required to make in the event of any such liabilities.

As more fully described under the caption “Underwriting” in the prospectus supplement, dated August 4, 2015, filed with the Securities and Exchange Commission on August 6, 2015, the Underwriter and certain of its affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for the Company and its affiliates, for which they received or may in the future receive customary fees and expenses.
