AMENDED
AND RESTATED PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT


 


THIS AMENDED AND RESTATED
PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, dated as of June 10, 2015 (as it may from time to time be amended, this “Agreement”),
is entered into by and between Electrum Special Acquisition Corporation, a British Virgin Islands company (the “Company”),
and ESAC Holdings LLC, a Delaware limited liability company (the “Purchaser”), amends and restates in its entirety,
the Private Placement Warrants Purchase Agreement made as of June 10, 2015, by and between the Company and the Purchaser.


 


The Company intends
to consummate an initial public offering of the Company’s units (the “Public Offering”), each unit consisting
of one ordinary share, of no par value, of the Company (a “Share”), and one warrant. Each warrant entitles the holder
to purchase one-half of one Share at an exercise price of $5.75 per half Share. The Purchaser has agreed to purchase 13,050,000
warrants in the aggregate (the “Private Placement Warrants”), at a price of $0.50 per warrant. Each Private Placement
Warrant entitles the holder to purchase one-half of one Share at an exercise price of $5.75 per half Share.


 


NOW THEREFORE, in consideration
of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

provisions of any agreement, instrument, order, judgment or decree to which the Purchaser is subject.


 


C.        Investment
Representations.


 


(i)        Pursuant
to Section 1 of this Agreement, the Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement
Warrants, the Shares issuable upon such exercise (collectively, the “Securities”) for the Purchaser’s own account,
for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.


 


(ii)        The
Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities
Act.


 


(iii)        The
Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the
registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth
and accuracy of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein
in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.


 


(iv)        The
Purchaser decided to enter into this Agreement not as a result of any general solicitation or general advertising within the meaning
of Rule 502(c) under the Securities Act.


 


(v)        The
Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials
relating to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the
opportunity to ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment
in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary
to make an informed investment decision with respect to the acquisition of the Securities.


 


(vi)        The
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on
or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities
by the Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(vii)        The
Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state
securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or
(2) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement,
neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state
securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, the Purchaser understands
that the SEC has taken the position that promoters or affiliates of a blank check company and their transferees, both before and
after an initial business combination, are deemed to be “underwriters” under the Securities Act when reselling the
securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available
for resale transactions of the Securities despite technical compliance with the requirements of such Rule, and the Securities can
be resold only through a registered offering or in reliance upon another exemption from the registration requirements of the Securities
Act.

(viii)        The
Purchaser has such knowledge and experience in financial and business matters, knows of the high degree of risk associated with
investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and
risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount
contemplated hereunder for an indefinite period of time. The Purchaser has adequate means of providing for its current financial
needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment
in the Securities. The Purchaser can afford a complete loss of its investment in the Securities.
