Form of Warrant Subscription Agreement



 Exhibit 10.6 
 WARRANT SUBSCRIPTION AGREEMENT, dated as of December 28, 2007 (this “Agreement”), by and between Grail Chalice SPAC Holdings LLC, a Delaware limited liability company (the “Purchaser”),
and Grail Investment Corp., a Delaware corporation (the “Company”). 
 INTRODUCTION 
 In connection with the consummation of the Company’s initial public offering (the “IPO”), the Company desires to issue and sell, and
Purchaser desires to purchase, on the terms and conditions set forth in this Agreement, 6,000,000 warrants (the “Insider Warrants”), each to purchase one share of the Company’s common stock, par value $0.0001 per share (the
“Common Stock”) at an initial exercise price of $7.50 per Insider Warrant. 
 The Insider Warrants shall have the terms set forth
in the warrant agreement to be entered into by and between the Company and Continental Stock Transfer & Trust Company (“Continental”), as Warrant Agent, in connection with the IPO, substantially in the form attached hereto as
Exhibit A (the “Warrant Agreement”). 
 In consideration of the premises and the mutual covenants and agreements contained
in this Agreement, Purchaser and the Company agree as follows: 
 1. Purchase and Sale of Insider Warrants. The purchase and sale of
the Insider Warrants shall occur simultaneously with the consummation of the IPO. At least 24 hours prior to the date of the final prospectus in connection with the IPO, the undersigned shall deliver $6,000,000 (the “Purchase Price”) to
Continental or such other agent as may be agreed to by the parties hereto (“Agent”) to hold in an account until the Company consummates the IPO. Simultaneously with the consummation of the IPO, Agent shall deposit the Purchase Price,
without interest or deduction, into a trust account established by the Company for the benefit of the Company’s public stockholders at JP Morgan Chase Bank and maintained by Continental, as trustee. In the event that the IPO is not consummated
within fourteen (14) days of the date the Purchase Price is delivered to Agent, Agent shall return the Purchase Price to the Purchaser, with accrued interest. 
 2. Terms of the Insider Warrants. Each Insider Warrant shall have the terms set forth in the Warrant Agreement. In connection with the IPO, the Company and Purchaser shall enter into an agreement granting
holders of the Insider Warrants registration rights with respect to the Insider Warrants and the shares of Common Stock issuable upon exercise of the Insider Warrants (the “Warrant Shares” and, together with the Insider Warrants, the
“Securities”). 
 3. Investment Representations and Covenants. 
 (a) Purchaser is acquiring the Insider Warrants for his, her or its own account, for investment only and not with a view towards, or for resale in
connection with, any public sale or distribution thereof. Unless a registration statement at the time of exercise of the Insider Warrants, the Purchaser covenants to acquire the Warrant Shares for his, her or its own account, for investment only and
not with a view towards, or for resale in connection with, any public sale or distribution thereof. 







 (b) Purchaser is an accredited investor as such term is defined in Rule 501 of Regulation D promulgated
by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Purchaser understands that its investment in the Securities involves a high degree of risk. Purchaser has sought such
accounting, legal and tax advice as Purchaser has considered necessary to make an informed decision with respect to the Purchaser’s acquisition of such Securities. Purchaser has knowledge and experience in financial and business matters and
knows of the high degree of risk associated with investments generally and particularly investments in the securities of development stage companies. Purchaser is able to bear the economic risk of an investment in the Securities in the amount
contemplated hereunder for an indefinite period of time. Purchaser can afford a complete loss of its investment in the Securities. Purchaser has had access to all information that it believes is necessary, sufficient or appropriate in connection
with the purchase of the Warrants. 
 (c) Purchaser understands that 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 (i) subsequently registered thereunder or (ii) sold in reliance on an exemption therefrom. No U.S. 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 nor have any such governmental authorities passed upon or
endorsed the merits of the offering of the Securities. 
 (d) 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 U.S. 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. 
 4. Certificates; Legends. 
 (a) The
certificates evidencing the Insider Warrants shall be substantially in the form attached as an exhibit to the Warrant Agreement and shall include a legend substantially in the following form:

ALL APLICABLE SECURITIES LAWS, AND, IN THE CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, ONLY IF THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY
SATISFACTORY TO THE COMPANY REGARDING THE AVAILABILITY OF SUCH EXEMPTION UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE LAWS. 
 (b)
Purchaser agrees, prior to any permitted transfer of the Securities, to give written notice to the Company expressing its desire to effect such transfer and describing briefly the proposed transfer. Upon receiving such notice, the Company shall
present copies thereof to its counsel. Purchaser shall not make any disposition of any Securities unless and until (i) there is then in effect a registration statement under the Securities Act covering such transfer and such transfer is made in
accordance with such registration statement or (ii) if reasonably requested by the Company, (x) Purchaser shall have furnished to the Company an opinion of counsel reasonably satisfactory to the Company that such disposition will not
require registration under the Securities Act and (y) the transferee shall have agreed to comply with the restrictions in the legend set forth in Section 4(a) above.
