NEW YORK CITY TIME, FIVE YEARS FROM THE CLOSING DATE OF THE COMPANY’S INITIAL 

BUSINESS COMBINATION)

 CUSIP __________ 

WARRANT 
 THIS WARRANT CERTIFIES THAT, for value
received                 , or registered agents, is the registered holder of a Warrant or Warrants (the “Warrant”), expiring on a date which is five
(5) years from the completion of the Company’s initial business combination, to purchase three quarters (3/4) of one fully paid and non-assessable share (the “Warrant Shares”), of common
stock, par value $0.0001 per share (the “Common Stock”), of PTK ACQUISITION CORP., a Delaware corporation (the “Company”), for each Warrant evidenced by this Warrant Certificate. This Warrant Certificate is subject to and shall
be interpreted under the terms and conditions of the Warrant Agreement (as defined below). 
 The Warrant entitles the holder thereof to
purchase from the Company, from time to time, in whole or in part, commencing on the later to occur of (i) the completion of the Company’s initial business combination or (ii) twelve (12) months following the closing of the
Company’s initial public offering, such number of Warrant Shares at the price of $11.50 per whole share (the “Warrant Price”), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency of
Continental Stock Transfer & Trust Company (the “Warrant Agent”), such payment to be made subject to the conditions set forth herein and in the Warrant Agreement, dated [•], 2020, between the Company and the Warrant Agent
(the “Warrant Agreement”). In no event shall the registered holder(s) of this Warrant be entitled to receive a net-cash settlement in lieu of physical settlement in Warrant Shares of the Company. The
Warrant Agreement provides that, upon the occurrence of certain events, the Warrant Price and the number of Warrant Shares purchasable hereunder, set forth on the face hereof, may be adjusted, subject to certain conditions. The term Warrant Price as
used in this Warrant Certificate refers to the price per full Warrant Share at which Warrant Shares may be purchased at the time the Warrant is exercised. 

This Warrant will expire on the date first referenced above if it is not exercised prior to such date by the registered holder pursuant to the
terms of the Warrant Agreement or if it is not redeemed by the Company prior to such date. 
 No fraction of a Share will be issued upon any
exercise of a Warrant. If, upon exercise of a Warrant, a holder would be entitled to receive a fractional interest in a Share, the Company will, upon exercise, issue or cause to be issued only the largest whole number of Warrant Shares issuable on
such exercise (and such fraction of a Share will be disregarded). 
 Upon any exercise of the Warrant for less than the total number of full
Warrant Shares provided for herein, there shall be issued to the registered holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Warrant Shares for which the Warrant has not been exercised. 

Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder(s) hereof in person or by
attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor
and evidencing in the aggregate a like number of Warrants. 












 Upon due presentment for registration of transfer of the Warrant Certificate at the office
or agency of the Warrant Agent, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the
limitations provided in the Warrant Agreement, without charge except for any applicable tax or other governmental charge. 
 The Company and
the Warrant Agent may deem and treat the registered holder(s) as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof, of any
distribution to the registered holder(s), and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

This Warrant does not entitle the registered holder(s) to any of the rights of a stockholder of the Company. 

After the Warrant becomes exercisable and prior to its expiration date, the Company reserves the right to call the Warrant at any time, with a
notice of call in writing to the holder(s) of record of the Warrant, giving thirty (30) days’ written notice of such call if the last reported sale price of the Common Stock has been equal to or greater than $16.50 per share for any twenty
(20) trading days within a thirty (30) trading day period ending on the third (3rd) trading day prior to the date on which notice of such call is given, provided that (i) a registration statement under the Securities Act of 1933, as
amended (the “Act”) with respect to the shares of Common Stock issuable upon exercise must be effective and a current prospectus must be available for use by the registered holders hereof or (ii) the Warrants may be exercised on
cashless basis as set forth in the Warrant Agreement and such cashless exercise is exempt from registration under the Act. The call price is $0.01 per Warrant Share. No fractional shares will be issued upon exercise of the Warrant. 

If the foregoing conditions are satisfied and the Company calls the Warrant for redemption, each holder will then be entitled to exercise his,
her or its Warrant prior to the date scheduled for redemption; provided that the Company may require the Registered Holder who desires to exercise the Warrant, to elect cashless exercise as set forth in the Warrant Agreement, and such Registered
Holder must exercise the Warrants on a cashless basis if the Company so requires. Any Warrant either not exercised or tendered back to the Company by the end of the date specified in the notice of call shall be canceled on the books of the Company
and have no further value except for the $0.01 call price.
