Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Organization and Business Operations

Organization and General

TPG Pace Energy Holdings Corp. (the “Company”) was incorporated in the state of Delaware on February 14, 2017 (“Inception”). The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The Company’s sponsor is TPG Pace Energy Sponsor, LLC, a Delaware limited liability company (the “Sponsor”), which is an affiliate of TPG Global, LLC.

On March 15, 2018, the Company formed three indirect wholly owned subsidiaries; TPG Pace Energy Parent LLC, TPG Pace Energy Intermediate LLC and TPG Pace Energy Operating LLC. All three entities are Delaware limited liability companies and were formed in contemplation of the Proposed Business Combination (as defined herein).

All activity for the period from Inception to March 31, 2018 relates to the Company’s formation and the initial public offering of units, each consisting of one of the Company’s shares of Class A common stock and one-third of one warrant to purchase one share of Class A common stock (the “Public Offering”), and the identification and evaluation of prospective acquisition targets for a Business Combination, including with respect to the Proposed Business Combination. The Company will not generate operating revenues prior to the completion of the Business Combination and will generate non-operating income in the form of interest income on Permitted Investments (as defined below) from the proceeds derived from the Public Offering. The Company has selected December 31st as its fiscal year end.

Financing

The registration statement for the Company’s Public Offering was declared effective by the United States Securities and Exchange Commission (the “SEC”) on May 4, 2017. The Public Offering closed on May 10, 2017 (the “Close Date”). The Sponsor purchased an aggregate of 10,000,000 warrants at a purchase price of $1.50 per warrant, or $15,000,000 in the aggregate, in a private placement on the Close Date (the “Private Placement”). The warrants are included in additional paid-in capital at the balance sheet.

The Company intends to finance a Business Combination with, among other things, proceeds from its $650,000,000 Public Offering (see Note 3) and $15,000,000 Private Placement (see Note 4). The proposed financing for the Proposed Business Combination is discussed below under “ Proposed Business Combination .” At the Close Date, proceeds of $650,000,000, net of underwriting discounts of $13,000,000 and funds designated for operational use of $2,000,000, were deposited in a trust account with Continental Stock Transfer and Trust Company acting as trustee (the “Trust Account”) as described below.

The Trust Account

On the Close Date, all funds held in the Trust Account were invested in U.S. government treasury bills with a maturity of 180 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations (collectively, “Permitted Investments”).

Funds will remain in the Trust Account except for the withdrawal of interest to fund working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes. The proceeds from the Public Offering will not be released from the Trust Account until the earliest of (i) the completion of the Business Combination, (ii) the redemption of any public shares properly submitted in connection with a stockholder vote to amend the amended and restated certificate of incorporation to modify the substance and timing of the Company’s obligation to redeem 100% of the public shares if the Company does not complete the Business Combination within 24 months from the Close Date, or (iii) the redemption of all of the Company’s public shares if it is unable to complete the Business Combination within 24 months from the Close Date, subject to applicable law. In addition, if the Company is unable to complete the Business Combination within 24 months from the Close Date for any reason, compliance with Delaware law may require that the Company submit a plan of dissolution to the then-existing stockholders for approval prior to the distribution of the proceeds held in the Trust Account.

5

Of the remaining proceeds of $2,000,000 held outside the Trust Account, $300,000 was used to repay the loan from the Sponsor, with the remainder av ailable to pay offering costs, business, legal and accounting due diligence on prospective acquisitions, listing fees and continuing general and administrative expenses.

Business Combination

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating a Business Combination with (or acquisition of) a target business. As used herein, the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the Company signing a definitive agreement.

After signing a definitive agreement for a Business Combination, the Company will provide the public stockholders with the opportunity to redeem all or a portion of their public shares either (i) in connection with a stockholder meeting to approve the Business Combination or (ii) by means of a tender offer. Each public stockholder may elect to redeem their shares irrespective of whether they vote for or against the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to fund its working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes, divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the Trust Account is initially anticipated to be approximately $10.00 per public share. The per share amount the Company will distribute to investors who properly redeem their shares will not be reduced by any deferred underwriting commissions payable to underwriters. The decision as to whether the Company will seek stockholder approval of the Business Combination or will allow stockholders to sell their shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek stockholder approval under the law or stock exchange listing requirements. If the Company seeks stockholder approval, it will complete its Business Combination only if a majority of the outstanding shares voted are voted in favor of the Business Combination. However, in no event will the Company redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001 after payment of the deferred underwriting commission. In such an instance, the Company would not proceed with the redemption of its public shares and the related Business Combination, and instead may search for an alternate Business Combination.

The Company has 24 months from the Close Date to complete its Business Combination. If the Company does not complete a Business Combination within this period, it shall (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds in the Trust Account and not previously released to the Company to fund its working capital requirements, subject to an annual limit of $750,000, and/or to pay its taxes (less up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. The Company’s Sponsor and four independent directors (collectively, “Initial Stockholders”) and the Company’s officers and directors have entered into a letter agreement with the Company, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to their Founder Shares (as defined in Note 4) if the Company fails to complete the Business Combination within 24 months from the Close Date. However, if the Initial Stockholders acquire public shares after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such public shares if the Company fails to complete the Business Combination within the allotted 24-month time period.

The underwriters have agreed to waive their rights to any deferred underwriting commission held in the Trust Account in the event the Company does not complete the Business Combination and those amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s public shares.

If the Company fails to complete the Business Combination, the redemption of the Company’s public shares will reduce the book value of the shares held by the Initial Stockholders, who will be the only remaining stockholders after such redemptions.

6

If the Company holds a stockholder vote or there is a tender offer for shares in connection with a Business Combination, a public stockholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the co nsummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to fund its working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes. As a result, such shares are recorded at their redemption amount and classified as temporary equity on the balance sheet, in accordance with ASC 480, “Distinguishing Liabilities from Equity.”

Proposed Business Combination

On March 20, 2018, the Company and TPG Pace Energy Parent LLC, a Delaware limited liability company and direct wholly owned subsidiary of the Company (“Pace LLC”), as applicable, entered into the following agreements:

At the closing of the Proposed Business Combination, the Company will acquire the Karnes County Assets, the Giddings Assets and the Ironwood Interests. On May 10, 2018, the Company, Pace LLC and the Karnes County Contributors entered into Amendment No. 1 to the Karnes Country Contribution Agreement to make certain changes in the forms of the Stockholder Agreement and the Second A&R Charter attached as exhibits to the Karnes County Contribution Agreement.

7

The following table summarizes certain material ter ms with respect to the Proposed Business Combination:

8

Unless waived by the parties to the Business Combination Agreements, the closing of the Proposed Business Combination is subject to a number of conditions set f orth in the Business Combination Agreements, including, among others, receipt of the requisite approval of the Company’s stockholders and the Company having at least $610,000,000 in Available Cash (as defined in the Karnes County Purchase Agreement). The o bligations of the Company and Pace LLC (but not the Karnes County Contributors) to consummate the Karnes County Transaction are conditioned upon the closing of the Giddings Transaction. The obligations of Pace LLC (but not the Giddings Sellers) to consumma te the Giddings Transaction are conditioned upon the closing of the Karnes County Transaction. The obligations of the parties to consummate the Ironwood Transaction are conditioned upon the closing of the Karnes County Transaction. The Business Combination Agreements may be terminated at any time prior to the consummation of the Proposed Business Combination upon agreement of the parties thereto, or for other reasons in specified circumstances. The Company (but not the Karnes County Contributors) may termin ate the Karnes County Contribution Agreement if the Giddings Purchase Agreement has been terminated in accordance with its terms. Pace LLC (but not the Giddings Sellers) may terminate the Giddings Purchase Agreement if the Karnes County Contribution Agreem ent has been terminated in accordance with its terms. Any party to the Ironwood MIPA may terminate such agreement if the Karnes County Contribution Agreement has been terminated in accordance with its terms.

Commitment Letters. On March 20, 2018, TPG Pace Energy Operating LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of the Company (“Pace Operating LLC”), entered into a debt commitment letter (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Debt Commitment Letter”) with the lender parties thereto (collectively, the “Commitment Parties”), pursuant to which the Commitment Parties committed to make available to Pace Operating LLC in accordance with the terms of the Debt Commitment Letter an RBL Facility in an aggregate principal amount of $1,000 million and a Senior Bridge Facility in an aggregate principal amount of $500,000,000 (less any proceeds received from the issuance of the Senior Notes on or prior to the Closing Date). The RBL Facility will have availability of $385,000,000 on the closing date of the Proposed Business Combination and an initial borrowing base of $550,000,000. The proceeds of the borrowings on the closing date of the Proposed Business Combination under the RBL Facility (if any) and the Senior Bridge Facility (if any), together with the proceeds from the issuance of the Senior Notes (if any), the PIPE Investment and the cash in the Trust Account, will be used to finance the cash portion of the consideration of the Proposed Business Combination, to fund redemptions of shares by public stockholders in connection with the Proposed Business Combination, to pay the costs, fees and expenses (including original issue discount and/or upfront fees and deferred underwriting expenses in respect of the Company’s initial public offering and fees and expenses payable pursuant to the Business Combination Agreements) associated with the Proposed Business Combination and for working capital and general corporate purposes.

The Company filed a preliminary proxy statement with the SEC in connection with the Proposed Business Combination on May 10, 2018 (the “Proxy Statement”). The Proxy Statement contains important information regarding the Proposed Business Combination.

For more information regarding the Proposed Business Combination, please see “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Proposed Business Combination.”

Going Concern

At March 31, 2018, the Company had current liabilities of $5,962,718 and negative working capital of $5,237,063 largely due to amounts owed for professional services associated with the Public Offering and operating of the Company. As discussed above, the Company has the ability to use annually up to $750,000 of interest earned from the Trust Account to fund working capital. The Company's ability to continue as a going concern is dependent upon its ability to consummate a Business Combination or have access to sufficient interest income from the Trust Account to fund expenses and negative working capital balances. If there is insufficient interest income available to pay such amounts in full or if a Business Combination does not occur, the Company will need to obtain additional funds to meet its liabilities. Management's options for obtaining additional working capital, to the extent needed, include potentially requesting loans from the Sponsor or affiliates of the Sponsor, or certain of the Company’s executive officers or directors. Additional funds could also be raised through a private offering of debt or equity. There can be no assurance that the Company will be able to raise such funds if they are needed. In addition, the Company’s Proposed Business Combination still has conditions upon which a successful completion is contingent. The uncertainty regarding the need for and ability to obtain such funding raises substantial doubt about the Company’s ability to continue as a going concern.

The accompanying unaudited interim condensed consolidated financial statements have been prepared on a going concern basis and do not include any adjustments that might arise as a result of uncertainties about the Company’s ability to continue as a going concern.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting and disclosure rules and regulations of the SEC, and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the Company’s financial position at March 31, 2018 and the results of operations and cash flows for the periods presented. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to such rules and regulations. Interim results are not necessarily indicative of results for the full year or any future periods. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed by the Company on February 14, 2018 with the SEC. As discussed above in Note 1, the accompanying unaudited interim condensed consolidated financial statements have been prepared on a going concern basis and do not include any adjustments that might arise as a result of uncertainties that exist about the Company’s ability to continue as a going concern.

Principles of Consolidation

The accompanying interim condensed consolidated financial statements include the accounts of the Company and the accounts of the Company’s wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.

Emerging Growth Company

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Cash

Cash and cash equivalents include cash on hand and on deposit at banking institutions as well as all highly liquid short-term investments with original maturities of 90 days or less. The Company did not have cash equivalents at March 31, 2018.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which at times, may exceed the Federal depository insurance coverage of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet due to their short-term nature.

Fair Value Measurement

ASC 820 establishes a fair value hierarchy that prioritizes and ranks the level of observability of inputs used to measure investments at fair value. The observability of inputs is impacted by a number of factors, including the type of investment, characteristics specific to the investment, market conditions and other factors. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements).

Investments with readily available quoted prices or for which fair value can be measured from quoted prices in active markets will typically have a higher degree of input observability and a lesser degree of judgment applied in determining fair value.

10

The three levels of the fair value hierarchy under ASC 820 are as follows:

Level I—Quoted prices (unadjusted) in active markets for identical investments at the measurement date are used.

Level II—Pricing inputs are other than quoted prices included within Level I that are observable for the investment, either directly or indirectly. Level II pricing inputs include quoted prices for similar investments in active markets, quoted prices for identical or similar investments in markets that are not active, inputs other than quoted prices that are observable for the investment, and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level III—Pricing inputs are unobservable and include situations where there is little, if any, market activity for the investment. The inputs used in determination of fair value require significant judgment and estimation.

In some cases, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the investment is categorized in its entirety is determined based on the lowest level input that is significant to the investment. Assessing the significance of a particular input to the valuation of an investment in its entirety requires judgment and considers factors specific to the investment. The categorization of an investment within the hierarchy is based upon the pricing transparency of the investment and does not necessarily correspond to the perceived risk of that investment.

The Permitted Investments are Level I at March 31, 2018.

Redeemable Common Stock

All 65,000,000 shares of Class A common stock sold as part of the Units (as defined below) in the Public Offering contain a redemption feature as discussed above. In accordance with ASC 480, redemption provisions not solely within the control of the Company require the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. Although the Company did not specify a maximum redemption threshold, its charter provides that in no event will it redeem its Class A common stock in an amount that would cause its net tangible assets, or total stockholders’ equity, to fall below $5,000,001. Accordingly, at March 31, 2018 and December 31, 2017, 62,284,034 and 62,438,263, respectively, of the Company’s 65,000,000 shares of Class A common stock were classified outside of permanent equity at their redemption value.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Offering Costs

The Company complies with the requirements of ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A “Expenses of Offering”. The Company incurred offering costs of $1,424,561 in connection with the Public Offering. These costs, together with the underwriter discount and Deferred Discount (as defined below), totaling $35,750,000, were charged to additional paid-in capital upon completion of the Public Offering.

Net Loss Per Share of Common Stock

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Net loss per share of common stock is computed by dividing net income by the weighted average number of common shares outstanding during the period as calculated using the treasury stock method. At March 31, 2018, the Company had outstanding warrants to purchase up to 31,666,666 shares of Class A common stock. The weighted average of these shares was excluded from the calculation of diluted net income per share of common stock since the exercise of the warrants is contingent upon the occurrence of future events. At March 31, 2018, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company under the treasury stock method. As a result, diluted net income per share of common stock is the same as basic net income per share of common stock for the period.

11

Income Taxes

Under ASC 740, “Income Taxes,” deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date. Valuation allowances are established when it is more likely than not that some or all of the deferred tax assets will not be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at March 31, 2018. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since Inception.

The Company has incurred costs related to the Proposed Business Combination which are expected to be deductible for federal income tax purposes if the Proposed Business Combination is completed. These costs generated a deferred tax asset of approximately $914,685 at March 31, 2018, which is currently available to offset future taxable income.

For the three months ended March 31, 2018 and the period from Inception to March 31, 2017, the Company incurred United States federal income tax benefits of approximately $409,975 and $22,121, respectively.

On September 15, 2017 and December 15, 2017, the Company made estimated quarterly tax payments of $400,000 and $407,000, respectively, to the Internal Revenue Service (“IRS”) for federal income taxes estimated for 2017 on interest earned in the Trust Account. The funds were paid from the Trust Account. At March 31, 2018 and December 31, 2017 the Company had accrued federal income taxes of $759,964 and $359,823, respectively.

State Franchise Tax

As the Company is incorporated in the state of Delaware, it is subject to Delaware state franchise tax which is computed based on an analysis of both authorized shares and total gross assets. At March 31, 2018 and December 31, 2017, the Company had accrued Delaware state franchise taxes of $50,000 and $152,610, respectively, included in accrued professional fees and other expenses on the balance sheet.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

3. Public Offering

In its Public Offering, the Company sold 65,000,000 units at a price of $10.00 per unit. Each unit consists of one share of Class A common stock of the Company at $0.0001 par value and one-third of one warrant (a “Unit”). Each whole warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share (a “Warrant”). Only whole Warrants may be exercised and no fractional Warrants will be issued upon separation of the Units and only whole Warrants may be traded. The Warrants will become exercisable on the later of 30 days after the completion of the Business Combination or 12 months from the Close Date, and will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. Alternatively, if the Company does not complete a Business Combination within 24 months after the Close Date, the Warrants will expire at the end of such period. If the Company is unable to deliver registered shares of Class A common stock to the holder upon exercise of Warrants issued in connection with the 65,000,000 Units during the exercise period, the Warrants will expire worthless, except to the extent that they may be exercised on a cashless basis in the circumstances described in the agreement governing the Warrants.

Once the Warrants become exercisable, the Company may redeem the outstanding Warrants in whole, but not in part, at a price of $0.01 per Warrant upon a minimum of 30 days’ prior written notice of redemption, and only in the event that the last sale price of the Company’s public shares equals or exceeds $18.00 per share for any 20 trading days within the 30-trading day period ending on the third trading day before the Company sends the notice of redemption to the Warrant holders. The Company has agreed to use its best efforts to file a registration statement for the shares of Class A common stock issuable upon exercise of the Warrants under the Securities Act as soon as practicable, but in no event later than 15 business days following the completion of a Business Combination.

12

The Company paid an underwriting discount of 2.00% of t he gross proceeds of the Public Offering, or $13,000,000, to the underwriters at the Close Date, with an additional fee (the “Deferred Discount”) of 3.50% of the gross proceeds of the Public Offering, or $22,750,000, payable upon the Company’s completion o f a Business Combination. The Deferred Discount will become payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completes a Business Combination. The underwriters are not entitled to receive any of the int erest earned on Trust Account funds that would be used to pay the Deferred Discount. The Deferred Discount has been recorded as a deferred liability on the balance sheet at March 31, 2018 as management has deemed the consummation of a Business Combination to be probable.

4. Related Party Transactions

Founder Shares

On February 22, 2017, the Sponsor purchased an aggregate of 11,500,000 shares of the Company’s Class F common stock (the “Founder Shares”) for an aggregate purchase price of $25,000, or approximately $0.002 per share. Prior to the Sponsor’s initial investment in the Company of $25,000, the Company had no assets. The purchase price of the Founder Shares was determined by dividing the amount of cash contributed to the Company by the number of Founder Shares issued by the Company.

On April 24, 2017, the Company agreed to effect a stock dividend prior to the closing of the Public Offering of approximately 0.5 shares of Class F common stock for each share of Class F common stock, which resulted in a total of 17,250,000 issued and outstanding Founder Shares. The stock dividend also adjusted the Founder Shares subject to forfeiture from 1,500,000 to 2,250,000 such that the Founder Shares would represent 20.0% of the Company’s issued and outstanding common shares after the Public Offering. The stock dividend was accounted for with a transfer from additional paid in capital to Class F common stock as there is a legal requirement to maintain par value per share. On April 24, 2017, the Sponsor transferred 40,000 Founder Shares to each of the Company’s four independent directors at their original purchase price. On June 24, 2017, the Sponsor forfeited 1,000,000 Founder Shares on the expiration of the underwriters’ over-allotment option. At March 31, 2018, the Initial Stockholders held, collectively, 16,250,000 Founder Shares.

The Founder Shares are identical to the Class A common stock included in the Units sold in the Public Offering except that:

Additionally, the Initial Stockholders have agreed not to transfer, assign or sell any of their respective Founder Shares until the earlier of (i) one year after the completion of the Business Combination or (ii) subsequent to the Business Combination, if the last sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination and (iii) the date following the completion of the Business Combination on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s public stockholders having the right to exchange their shares of Class A common stock for cash, securities or other property (the “Lock Up Period”).

Private Placement Warrants

On the Close Date, the Sponsor purchased from the Company an aggregate of 10,000,000 private placement warrants at a price of $1.50 per warrant, or approximately $15,000,000, in the Private Placement (the “Private Placement Warrants”). Each Private Placement Warrant entitles the holder to purchase one share of Class A common stock at $11.50 per share, subject to adjustment. A portion of the purchase price of the Private Placement Warrants was placed in the Trust Account. The Private Placement Warrants will not be redeemable by the Company so long as they are held by the Sponsor or its permitted transferees. If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable

13

by the Company and exercisable by the holders on the same basis as the warrants included in the Units sold i n the Public Offering. The Sponsor, or its permitted transferees, will have the option to exercise the Private Placement Warrants on a cashless basis. The Private Placement Warrants will not be transferable, assignable or salable until 30 days after the co mpletion of the Business Combination.

If the Company does not complete the Business Combination within 24 months from the Close Date, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Company’s public shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

During the period from August 18, 2017 to August 23, 2017, the Company’s Chief Executive Officer purchased a total of 27,900 Units in a series of open market transactions at a weighted average price of $10.24 per Unit.

Registration Rights

Holders of the Founder Shares and Private Placement Warrants are entitled to registration rights pursuant to a registration rights agreement signed on the effective date of the Public Offering (the “Initial Registration Rights Agreement”). The holders of these securities are entitled to make up to three demands that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to other registration statements filed by the Company subsequent to its completion of the Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the Initial Registration Rights Agreement provides that that Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable Lock Up Period. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Indemnity

The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a vendor (other than the Company’s independent auditors) for services rendered or products sold to the Company, or a prospective target business with which the Company discussed entering into a transaction agreement, reduces the amount of funds in the Trust Account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to fund the Company’s working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Public Offering against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. The Company has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believes that the Sponsor’s only assets are securities of the Company and, therefore, the Sponsor may not be able to satisfy those obligations. The Company has not asked the Sponsor to reserve for such eventuality as the Company believes the likelihood of the Sponsor having to indemnify the Trust Account is limited because the Company will endeavor to have all vendors and prospective target businesses as well as other entities execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Related Party Note Payable

Between Inception and the Close Date, the Company’s Sponsor loaned the Company $300,000 in unsecured promissory notes. The funds were used to pay up front expenses associated with the Public Offering. These notes were non-interest bearing and were repaid in full to the Sponsor at the Close Date.

PIPE Investment

The Company agreed to issue and sell in a private placement 1,500,000 shares of Class A Common Stock (the “PIPE Investment”)  to Stephen Chazen, the Company’s President, Chief Executive Officer and Chairman, and 1,000,000 shares of Class A Common Stock to TPG Holdings III, L.P. (“TPG Holdings”). Prior to the closing of the Proposed Business Combination, TPG Holdings expects to assign its right to purchase Class A Common Stock in connection with the PIPE Investment to certain TPG executives, which the Company expects will include two of the Company’s directors, David Bonderman and Michael MacDougall, and the Company’s Executive Vice President of Corporate Development and Secretary, Eduardo Tamraz. The PIPE Investment is conditioned upon the satisfaction or waiver of all conditions precedent to the closing of the Karnes County Transaction and other customary conditions, and is expected to close concurrently with, the Proposed Business Combination.
