The Offer does not relate to the warrants issued to affiliates in private placements that occurred contemporaneously with our initial public offering. Any and all outstanding Public Warrants are eligible to be tendered pursuant to the Offer.

The undersigned hereby instructs you to exchange the number of Public Warrants indicated below or, if no number is indicated, all Public Warrants you hold for the account of the undersigned, on the terms and subject to the conditions of the Offer.

By participating in the Offer, the undersigned acknowledges that: (i) the Offer is discretionary and may be extended, modified, suspended or terminated by the Company as provided in the Offer Letter; (ii) such Public Warrant holder is voluntarily participating in the Offer; (iii) the future value of the Public Warrants is unknown and cannot be predicted with certainty; (iv) such Public Warrant holder has read the Offer Letter; (v) such Public Warrant holder has consulted his, her or its tax and financial advisors with regard to how the Offer will impact the tendering Public Warrant holder’s specific situation; (vi) any foreign exchange obligations triggered by such Public Warrant holder’s tender of Public Warrants or receipt of proceeds are solely his, her or its responsibility; and (vii) regardless of any action that the Company takes with respect to any or all income/capital gains tax, social security or insurance tax, transfer tax or other tax-related items (“Tax Items”) related to the Offer and the disposition of Public Warrants, such Public Warrant holder acknowledges that the ultimate liability for all Tax Items is and remains his, her or its sole responsibility. In that regard, a tender of Public Warrants authorizes the Company to withhold all applicable Tax Items potentially payable by a tendering Public Warrant holder. The Company’s acceptance for payment of Public Warrants tendered pursuant to the Offer will constitute a binding agreement between the tendering Public Warrant holder and the Company upon the terms and subject to certain conditions of the Offer.
