Each holder of our common stockCommon Stock is entitled to one vote per share on each matter submitted to a vote of stockholders, unless otherwise provided by our certificate of incorporation. Our bylaws provide that the presence, in person or by proxy, of holders of shares representing a majority of the issued and outstanding shares of capital stock entitled to vote at a stockholders’ meeting shall constitute a quorum. When a quorum is present, the affirmative vote of a majority of the votes cast is required to take action, unless otherwise specified by law, our bylaws, our certificate of incorporation or our Stockholders’ Agreement. There are no cumulative voting rights.

Warrants
Our warrants are issued under the Amended and Restated Warrant Agreement, dated as of July 31, 2019 between Continental Stock Transfer & Trust Company, as warrant agent, and the Company. The following summary of certain provisions relating to our warrants does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the Amended and Restated Warrant Agreement. Each of our outstanding warrants is exercisable for one share of our common stock at a price of $11.50 per share, beginning 30 days from the completion of the Transactions, subject to adjustment as discussed below. The warrants will expire at 5:00 p.m., New York City time, five years after the completion of the Transactions or earlier upon redemption or liquidation.
We may call the warrants for redemption (excluding the private warrants that continue to be held by the holders holding such private warrants as of the date of any such redemption), in whole and not in part, at a price of $0.01 per warrant,

at any time while the warrants are exercisable;
upon not less than 30 days’ prior written notice of redemption to each warrant holder;
if, and only if, the reported last sale price of the common stock equals or exceeds $18.00 per share, for any 20 trading days within a 30-day trading period ending on the third business day prior to the notice of redemption to warrant holders; and
if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants commencing five business days prior to the 30-day trading period and continuing each day thereafter until the date of redemption.
The warrants will be forfeited unless exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.
If we call the warrants for redemption as described above, our management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock of the Company underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. In this case, the “fair market value” will mean the average reported last sale price of the shares of our common stock for the ten trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. Whether we will exercise our option to require all holders to exercise their warrants on a “cashless basis” will depend on a variety of factors including the price of shares of our common stock at the time the warrants are called for redemption, our cash needs at such time and concerns regarding dilutive stock issuances.
The private warrants (including the common stock issuable upon exercise thereof) will not be redeemable by us and may be exercisable for cash or on a cashless basis so long as they are held by the initial holders or their permitted transferees. The holders of the private warrants agreed to additional transfer restrictions relating to its common stock pursuant to the Stockholders’ Agreement. Otherwise, the private warrants have terms and provisions that are identical to those of the public warrants. If the private warrants are held by holders other than the initial holders thereof or their permitted transferees, the private warrants will be redeemable by us and exercisable by the holders on the same basis as the public warrants. If holders of the private warrants elect to exercise them on a cashless basis, they will pay the exercise price by surrendering his, her or its private warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the private warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. In this case, the “fair market value” shall mean the average reported last sale price of the common stock for the 10 trading days ending on the third trading day prior to the date of exercise.
The exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or our recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuances of shares of common stock at a price below their respective exercise prices.
The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of our common stock or any voting rights unless and until they exercise their warrants and receive shares of common stock. After the issuance of shares of our common stock upon exercise of the warrants, each holder will be entitled to one vote for each share of common stock held of record on all matters to be voted on by stockholders.
Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 4.9% or 9.8% (as specified by the holder) of the shares of our common stock outstanding immediately after giving effect to such exercise.
No fractional shares of common stock will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share of common stock, we will, upon exercise, follow the requirements of the Delaware General Corporation Law (the “DGCL”).

Certain Anti-Takeover Provisions of Delaware Law and Our Certificate of Incorporation

We have certain anti-takeover provisions in place as follows:

Staggered Board of Directors

Our certificate of incorporationcharter provides that ourthe board of directors be classified into three classes of directors of approximately equal size. As a result, in most circumstances, a person can gain control of our board only by successfully engaging in a proxy contest at two or more annual meetings. Furthermore, because the board will beis classified, directors may be removed only with cause by a majority of our outstanding shares.

Action by Written Consent; Special Meetingmeeting of Stockholders

stockholders

Our charter provides that stockholder action may only be taken by written consent in lieu of a meeting while Platinum Equity Advisors, LLC (“Platinum”) and its affiliates collectively beneficially own, in the aggregate, at least 50% in voting power of the stock of the Company entitled to vote generally in the election of directors, any action required or permitted to be taken at any annual or special meeting of stockholders of the Company.

The DGCLGeneral Corporation Law of the State of Delaware (the “DGCL”) provides that special meetings of our stockholders may be called by the board of directors.

Our charter provides that, at any time when Platinum and its affiliates collectively beneficially own, in the aggregate, at least 5% in voting power of the stock of the Company entitled to vote generally in the election of directors, the Chairman of the Board shall call a special meeting of stockholders at the request of Platinum from time to time.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our bylaws requireprovide that stockholders must comply with certain procedures in orderseeking to bring business before our annual meeting of stockholders, or to nominate candidates to our board offor election as directors or to propose matters to be acted upon at our annual meeting of stockholders.stockholders, must provide timely notice of their intent in writing. To be timely, a stockholder’s notice will need to be received by the company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the open of business on the 120th day prior to the anniversary date of the immediately preceding general meeting of stockholders (except that, with respect to Platinum’s nomination of directors, the reference to 90 days shall be 45 days). Such notice also must fulfill certain information requirements with respect to the stockholder delivering such notice and the matter proposed (or director candidate nominated) of which Platinum is partially exempt. Pursuant to Rule 14a-8 of the Exchange Act, proposals seeking inclusion in our annual proxy statement must comply with the notice periods contained therein. Our bylaws also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before the general meeting of stockholders or from making nominations for directors at our general meeting of stockholders.

Authorized but Unissued Shares

Our authorized but unissued common stockCommon Stock and preferred stock will be available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stockCommon Stock and preferred stock could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum Selection

Our certificate of incorporation requires, to the fullest extent permitted by law, that, unless we consent in writing to the selection of an alternative forum, derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware (or, in the event that the Court of Chancery of the State of Delaware does not have jurisdiction (such as in the case of claims brought to enforce any liability or duty created by the Exchange Act, in which case federal courts have exclusive jurisdiction), the federal district court for the District of Delaware or other state courts of the State of Delaware) and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel. This exclusive forum provision applies to state and federal law claims brought by stockholders (including claims pursuant to the Securities Act and the Exchange Act), although stockholders will not be deemed to have waived the Company’s compliance with the federal securities laws and the rules and regulations thereunder. The enforceability of similar choice of forum provisions in other companies’ organizational documents has been challenged in legal proceedings, and it is possible that, in connection with claims arising under federal securities laws, a court could find the choice of forum provisions contained in our Certificate of Incorporationcharter to be inapplicable or unenforceable. Although we believe this provision benefits our company by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Section 203 of the Delaware General Corporation Law

Business Combinations with Interested Stockholders

Our charter provides that we are not subject to Section 203 of the DGCL, provides that ifan anti-takeover law. In general, Section 203 prohibits a person acquires 15% or more of the voting stock of apublicly held Delaware corporation from engaging in a business combination, such person becomesas a merger, with an “interested stockholder” and may not engage in certain “business combinations” with the corporation for(which includes a period of three years from the time such person acquiredor group owning 15% or more of the corporation’s voting stock, unless: (1)stock) for a period of three years following the board of directors approves the acquisition of stock or the merger transaction before the time thatdate the person becomesbecame an interested stockholder, (2)unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder owns at least 85%is approved in a prescribed manner. Accordingly, we are not subject to any anti-takeover effects of Section 203. Nevertheless, our charter will contain provisions that will have a similar effect to Section 203, except that they will provide that (i) Platinum; (ii) Energy Capital Partners, LLC, a Delaware limited liability company, Energy Capital Partners II, LLC, Energy Capital Partners III, LLC, Energy Capital Partners Mezzanine, LLC, Energy Capital Partners IV, LLC, Energy Capital Partners Credit Solutions II, LLC, ECP ControlCo, LLC, Energy Capital Partners Holdings, LP, ECP Feeder, LP, and ECP Management GP, LLC; (iii) Capitol Acquisition Management IV LLC and Capitol Acquisition Founder IV LLC; and (iv) Blackstone Management Partners L.L.C. and their respective direct and indirect transferees will not be deemed to be “interested stockholders,” regardless of the outstanding voting stockpercentage of the corporation at the time the merger transaction commences (excludingCompany’s voting stock owned by directors who are also officersthem, and certain employee stock plans), or (3) the merger transaction is approved by the board of directors and at a meeting of stockholders,accordingly will not by written consent, by the affirmative vote of 2/3 of the outstanding voting stock which is not owned by the interested stockholder. A Delaware corporation may elect in its certificate of incorporation or bylaws not to be governed by this particular Delaware law. As set forth in our certificate of incorporation, we have opted out of, and are therefore not subject to Section 203 of the DGCL.

such restrictions.

Limitation on Liability and Indemnification of Directors and Officers

Our certificate of incorporationcharter provides that directors and officers will be indemnified by us to the fullest extent authorized by Delaware law as it now exists or may in the future be amended. In addition, our certificate of incorporationcharter provides that directors will not be personally liable for monetary damages to the Company for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to usthe Company or ourits stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

Our bylaws also permit usthe Company to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware law would permit indemnification. Upon consummation of the Transactions, we willWe have purchased a policy of directors’ and officers’ liability insurance that insures ourits directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances and insures usit against ourthe obligations to indemnify the directors and officers.

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit usthe Company and ourits stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we paythe Company pays the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

We are offering the shares of common stock underlying our warrants upon the exercise of the warrants by the holders thereof. The warrants may be exercised upon the surrender of the certificate evidencing such warrant on or before the expiration date at the offices of the warrant agent, Continental Stock Transfer

LEGAL MATTERS

Latham & Trust Company, in the Borough of Manhattan, City and State of New York, with the subscription form, as set forth in the warrants, duly executed, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. Additionally, the warrants (excluding the private warrants that continue to be held by the holders holding such private warrants as of the date of any such redemption) will be required to be exercised on a cashless basis in the event of a redemption of the warrants pursuant to the warrant agreement governing our warrants in which our board of directors has elected to require all holders of the warrants who exercise their warrants to do so on a cashless basis. In such event, such holder will exercise his, her or its warrants on a cashless basis by paying the exercise price by surrendering his, her or its warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants to be exercised, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. In this case, the “fair market value” will mean the average reported last sale price of the shares of our common stock for the ten trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

The private warrants (including the common stock issuable upon exercise thereof) will not be redeemable by us and may be exercisable for cash or on a cashless basis so long as they are held by the initial holders or their permitted transferees. If the private warrants are held by holders other than the initial holders thereof or their permitted transferees, the private warrants will be redeemable by us and exercisable by the holders on the same basis as the public warrants. If holders of the private warrants elect to exercise them on a cashless basis, they will pay the exercise price by surrendering his, her or its private warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the private warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. In this case, the “fair market value” shall mean the average reported last sale price of the common stock for the 10 trading days ending on the third trading day prior to the date of exercise.
No fractional shares will be issued upon the exercise of the warrants. If, upon the exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon the exercise, round up to the nearest whole number the number of shares of common stock to be issued to such holder.

Item 15. Indemnification of Directors and Officers

Subsection (a) of Section 145 of the General Corporation Law of the DGCL empowers a corporation to indemnify any person who was or is a party or who is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Subsection (b) of Section 145 empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 145 further provides that to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the indemnification provided for by Section 145 shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person’s heirs, executors and administrators. Section 145 also empowers the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.

With respect to any such Proceeding initiated by any such indemnified person, the Company will be required to indemnity such person only if the Proceeding was authorized in the specific case by the board of directors of the Company.

The Company entered into indemnification agreements with its directors and executive officers, in addition to the indemnification provided for in its certificate of incorporation and bylaws, and intends to enter into indemnification agreements with any new directors and executive officers in the future.

(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;

II-3

(ii)To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§ 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and


II-3



in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§ 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

Registration Statement.

(2)That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)
Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-4

(5)That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned Registrant;registrant;

(iii)the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.


II-4



(b)The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
