Exhibit 4.5 

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

As of March 13, 2020, Pure Acquisition Corp. (the “Company”) has three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): (1) our units; (2) our common stock; and (3) our warrants.

The following description of our units, common stock, and warrants is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to our second amended and restated certificate of incorporation, dated as of April 10, 2018, as amended by that certain certificate of amendment to certificate of incorporation of the Company, effective as of April 12, 2018, as further amended by that certain third amendment to the second amended and restated certificate of incorporation of the Company, effective as of February 20, 2020 (collectively, our “Charter”) and our Bylaws (the “Bylaws”), each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.5 is a part. We encourage you to read our Charter, our Bylaws and the applicable provisions of Delaware General Corporations Law (Title 8, Chapter 1 of the Delaware Code).

Terms not otherwise defined herein shall have the meaning assigned to them in the Annual Report on Form 10-K of which this Exhibit 4.5 is a part.

1.             Description of Units

Each unit consists of one share of common stock and one-half of one redeemable warrant. Each warrant entitles the holder thereof to purchase one share of our common stock at a price of  $11.50 per share, subject to adjustment in either case as described in the prospectus filed with the SEC on April 16, 2018 (File No. 333-223845) (the “Prospectus”). Pursuant to the warrant agreement, a warrantholder may exercise its warrants only for a whole number of shares of common stock. No fractional shares will be issued upon exercise of the warrants.

2.             Description of Common Stock

Pursuant to our Charter, our authorized capital stock consists of 200,000,000 shares of common stock, $0.0001 par value and 1,000,000 shares of preferred stock, $0.0001 par value.

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Unless specified in our Charter or Bylaws, or as required by applicable law or stock exchange rules, the affirmative vote of a majority of our shares of common stock that are voted is required to approve any such matter voted on by our stockholders (including the election of directors). Our board of directors is divided into three classes, each of which, other than the initial term, generally serves for a term of three years with only one class of directors being elected in each year. There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors. Our stockholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor.

Because our Charter authorizes the issuance of up to 200,000,000 shares of common stock, if we were to enter into an initial business combination, we may (depending on the terms of such an initial business combination) be required to increase the number of shares of common stock which we are authorized to issue at the same time as our stockholders vote on the initial business combination to the extent we seek stockholder approval in connection with our initial business combination.

We will provide our stockholders with the opportunity to redeem all or a portion of their public shares upon the completion of our initial 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 our initial business combination including interest earned on the funds held in the trust account and not previously released to us to pay our franchise and income taxes, divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the trust account is anticipated to be approximately $10.10 per public share at December 31. 2019. The per-share amount we will distribute to investors who properly redeem their shares will not be reduced by the fee payable to EarlyBirdCapital and Oppenheimer & Co. Inc. (or, at our discretion, other FINRA members) pursuant to the terms of the business combination marketing agreement. Our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to any founders shares and any public shares held by them in connection with the completion of our initial business combination. Unlike many blank check companies that hold stockholder votes and conduct proxy solicitations in conjunction with their initial business combinations and provide for related redemptions of public shares for cash upon completion of such initial business combinations even when a vote is not required by law, if a stockholder vote is not required by law and we do not decide to hold a stockholder vote for business or other legal reasons, we will, pursuant to our Charter, conduct the redemptions pursuant to the tender offer rules of the SEC, and file tender offer documents with the SEC prior to completing our initial business combination. Our Charter requires these tender offer documents to contain substantially the same financial and other information about the initial business combination and the redemption rights as is required under the SEC’s proxy rules. If, however, a stockholder approval of the transaction is required by law, or we decide to obtain stockholder approval for business or other legal reasons, we will, like many blank check companies, offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If we seek stockholder approval, we will complete our initial business combination only if a majority of the outstanding shares of common stock voted are voted in favor of the initial business combination. A quorum for such meeting will consist of the holders present in person or by proxy of shares of outstanding capital stock of the company representing a majority of the voting power of all outstanding shares of capital stock of the company entitled to vote at such meeting.

However, the participation of our sponsor, officers, directors, advisors or their affiliates in privately-negotiated transactions (as described in the Prospectus), if any, could result in the approval of our initial business combination even if a majority of our public stockholders vote, or indicate their intention to vote, against such business combination.

If we seek stockholder approval in connection with our initial business combination, pursuant to the letter agreement our sponsor, officers and directors have agreed to vote their founders shares and any public shares purchased during or after the Public Offering (including in open market and privately negotiated transactions) in favor of our initial business combination. Additionally, each public stockholder may elect to redeem its public shares irrespective of whether they vote for or against the proposed transaction (subject to the limitation described in the preceding paragraph).

We will consummate our initial business combination only if we have net tangible assets of at least $5,000,001 upon consummation of the initial business combination. 

Pursuant to our Charter, if we are unable to complete our initial business combination by May 21, 2020, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no 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 our franchise and income taxes (less up to $50,000 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 our remaining stockholders and our board of directors, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their rights to liquidating distributions from the trust account with respect to any founders shares held by them if we fail to complete our initial business combination by May 21, 2020. However, if our initial stockholders acquire public shares in or after the Public Offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the prescribed time period.

3.             Description of Founders Shares

The founders shares are identical to the shares of common stock, and holders of founders shares have the same stockholder rights as public stockholders, except that (i) the founders shares are subject to certain transfer restrictions, as described in more detail below, (ii) our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed (A) to waive their redemption rights with respect to any founders shares and any public shares held by them in connection with the completion of our initial business combination, (B) to waive their redemption rights with respect to their founders shares and public shares in connection with a stockholder vote to approve an amendment to our Charter to modify the substance or timing of our obligation to redeem 100% of our public shares if we do not complete our initial business combination by May 21, 2020 and (C) to waive their rights to liquidating distributions from the trust account with respect to any founders shares held by them if we fail to complete our initial business combination by May 21, 2020, although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within such time period, and (iii) the holders of founders shares are entitled to registration rights. If we submit our initial business combination to our public stockholders for a vote, our sponsor, officers and directors have agreed pursuant to the letter agreement to vote any founders shares held by them and any public shares purchased during or after the Public Offering (including in open market and privately negotiated transactions) in favor of our initial business combination. 

With certain limited exceptions, the founder shares are not transferable, assignable or salable (except to our officers and directors and other persons or entities affiliated with our sponsor, each of whom are subject to the same transfer restrictions) until the earlier of  (A) one year after the completion of our initial business combination or (B) subsequent to our initial business combination, (x) if the last sale price of our 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 our initial business combination, or (y) the date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of our stockholders having the right to exchange their shares of common stock for cash, securities or other property.

4.             Description of Public Redeemable Warrants

Each warrant entitles the registered holder thereof to purchase one share of our common stock at a price of $11.50 per share. Pursuant to the warrant agreement, a warrantholder may exercise its warrants only for a whole number of shares of common stock. This means that no fractional shares will be issued upon exercise of the warrants. The warrants will expire five years after the completion of our initial business combination or earlier upon redemption or liquidation.

We are not obligated to deliver any shares of common stock pursuant to the exercise of a warrant and have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of common stock underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration. No warrant will be exercisable and we will not be obligated to issue shares of common stock upon exercise of a warrant unless common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will we be required to settle any warrant on a cashless basis. In the event a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the share of common stock underlying such unit.

We have agreed that as soon as practicable, but in no event later than 15 business days after the closing of our initial business combination, we will use our best efforts to file with the SEC a registration statement covering the shares of common stock issuable upon exercise of the warrants, to cause such registration statement to become effective and to maintain a current prospectus relating to those shares of common stock until the warrants expire or are redeemed, as specified in the warrant agreement.

Once the warrants become exercisable, we may call the warrants for redemption:

● in whole and not in part;

● at a price of $0.01 per warrant;

● upon not less than 30 days’ prior written notice of redemption to each warrantholder; and if, and only if, the reported last sale price of the common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three business days before we send the notice of redemption to the warrantholders.​

If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. We will use our best efforts to register or qualify such shares of common stock under the blue sky laws of the state of residence in those states in which the warrants were offered by us in the Public Offering.

We have established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrantholder will be entitled to exercise its warrant prior to the scheduled redemption date. However, the price of the common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 warrant exercise price after the redemption notice is issued.

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 Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock 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. The “fair market value” shall mean the average reported last sale price of the shares of Class A common stock for the five 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.   

5.             Description of Private Placement Warrants

The private placement warrants (including the common stock issuable upon exercise of the private placement warrants) will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except, among other limited exceptions as described in the Prospectus). Otherwise, the private placement warrants have terms and provisions that are identical to those of the warrants being sold as part of the units in the Public Offering, except the private placement warrants will not be redeemable by us so long as they are held by the initial purchasers or their permitted transferees.

In order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. Up to $1,500,000 of such working capital loans may be convertible into additional warrants at a price of $1.00. Such warrants would be identical to the private placement warrants, including as to exercisability and exercise price.  

In addition, holders of our private placement warrants are entitled to certain registration rights. Our sponsor has agreed not to transfer, assign or sell any of the private placement warrants (including the underlying securities and the common stock issuable upon exercise of any of the private placement warrants) until the date that is 30 days after the date we complete our initial business combination, except that, among other limited exceptions as described in the Prospectus.
