Description of Organization and Business Operations	Note 1—Description of Organization and Business Operations *Organization and General* Kayne Anderson Acquisition Corp. (the “Company”) was incorporated in Delaware on December 12, 2016. 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 “Initial Business Combination”). We intend to focus our search for a target business in the energy industry. 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”). At March 31, 2017, the Company had not commenced any operations. All activity for the three months ended March 31, 2017 relates to the Company’s formation and the initial public offering (“Public Offering”) described below. On April 4, 2017, the Company closed its Public Offering (See Note 3 and Note 6). The Company will not generate any operating revenues until after completion of its Initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Public Offering. The Company has selected December 31 as its fiscal year end. *Sponsor* The Company’s sponsor is Kayne Anderson Sponsor, LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Public Offering (as described in Note 3) was declared effective by the United States Securities and Exchange Commission (the “SEC”) on March 29, 2017. *The Trust Account* The proceeds held in the trust account with American Stock Transfer & Trust Company, LLC acting as trustee (the “Trust Account”) will be invested only in U.S. government treasury bills with a maturity of one hundred eighty (180) days or less or in money market funds that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”) and that invest only in direct U.S. government obligations. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Initial Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. The Company’s amended and restated certificate of incorporation provides that, other than the withdrawal of interest to pay taxes, if any, none of the funds held in the Trust Account will be released until the earlier of: (i) the completion of the Initial Business Combination; (ii) the redemption of any shares of Class A Common Stock included in the units (the “Public Shares”) sold in the Public Offering that have been properly tendered in connection with a stockholder vote to amend the Company’s certificate of incorporation to modify the substance or timing of its obligation to redeem 100% of such shares of Class A Common Stock if it does not complete the Initial Business Combination within 24 months from the closing of the Public Offering; and (iii) the redemption of 100% of the shares of Class A Common Stock included in the Units sold in the Public Offering if the Company is unable to complete an Initial Business Combination within 24 months from the closing of the Public Offering (subject to the requirements of law). The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public stockholders. Initial 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 an Initial Business Combination. The Initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into the Initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an Initial Business Combination. The Company, after signing a definitive agreement for an Initial Business Combination, will either (i) seek stockholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable, or (ii) provide stockholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. The decision as to whether the Company will seek stockholder approval of the Initial Business Combination or will allow stockholders to sell their Public 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, unless a vote is required by law or under rules of The Nasdaq Stock Market. If the Company seeks stockholder approval, it will complete its Initial Business Combination only if a majority of the outstanding shares of common stock voted are voted in favor of the Initial 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 upon consummation of the Initial Business Combination. In such case, the Company would not proceed with the redemption of its Public Shares and the related Initial Business Combination, and instead may search for an alternate Initial Business Combination. If the Company holds a stockholder vote or there is a tender offer for shares in connection with an Initial 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 consummation of the Initial Business Combination, including interest but less taxes payable. As a result, such shares of Class A Common Stock will be recorded at redemption amount and classified as temporary equity upon the completion of the Public Offering, in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, “Distinguishing Liabilities from Equity.” Pursuant to the Company’s amended and restated certificate of incorporation, if the Company is unable to complete the Initial Business Combination within 24 months from the closing of the Public Offering, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, subject to lawfully available funds therefor, 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 held in the Trust Account and not previously released to us to pay the Company’s franchise and income 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 liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s 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 Sponsor and the Company’s officers and directors have entered into letter agreements with the Company, pursuant to which they have agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined below) held by them if the Company fails to complete the Initial Business Combination within 24 months of the closing of the Public Offering. However, if the Sponsor or any of the Company’s directors, officers or affiliates acquire shares of Class A Common Stock in or after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete the Initial Business Combination within the prescribed time period. In the event of a liquidation, dissolution or winding up of the Company after an Initial Business Combination, the Company’s stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock. The Company’s stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock, except that the Company will provide its stockholders with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Initial Business Combination, subject to the limitations described herein.

Initial 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 an Initial Business Combination. The Initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into the Initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an Initial Business Combination.

The Company, after signing a definitive agreement for an Initial Business Combination, will either (i) seek stockholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable, or (ii) provide stockholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable.

Pursuant to the Company’s amended and restated certificate of incorporation, if the Company is unable to complete the Initial Business Combination within 24 months from the closing of the Public Offering, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, subject to lawfully available funds therefor, 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 held in the Trust Account and not previously released to us to pay the Company’s franchise and income 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 liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s 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.
