Gentlemen:

This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between Highlands Acquisition Corp., a Delaware corporation (the “Company”), and Citigroup Global Markets Inc., as Representative (the “Representative”) of the several Underwriters named in Schedule I thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”), each comprised of one share of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), and one warrant exercisable for one share of Common Stock (each, a “Warrant”). Certain capitalized terms used herein are defined in Section 17 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such IPO will confer upon the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company as follows:

1. If the Company solicits approval of its stockholders of a Business Combination, the undersigned will (i) vote all shares of Founders’ Common Stock included in the Founders’ Units beneficially owned by him, her or it in accordance with the majority of the votes cast by the holders of the IPO Shares and in favor of an amendment to the Company's Amended & Restated Certificate of Incorporation to provide for the Company's perpetual existence and (ii) vote all other shares of the Company’s Common Stock that may be acquired by him, her or it in the IPO or in the aftermarket in favor of such Business Combination.

 

---

2. In the event that the Company fails to consummate a Business Combination within 24 months from the effective date (“Effective Date”) of the registration statement relating to the IPO, the undersigned will, as promptly as possible, (i) cause the Trust Account to be liquidated and distributed to the holders of IPO Shares and (ii) cause the Company to liquidate as soon as reasonably practicable. The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account and any remaining net assets of the Company as a result of such liquidation with respect to his shares of Founders’ Common Stock (“Claim”) and hereby waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever; provided, however, that in the event that the Company fails to consummate a Business Combination and the Trust Account is liquidated and distributed, nothing herein shall prevent the undersigned from participating in the Trust Account pro rata with the Company’s public stockholders with respect to any shares of Common Stock purchased by the undersigned as part of the IPO or in the aftermarket. In the event of the liquidation of the Trust Account, Ivy Capital Partners, of which the undersigned is co-founder, agrees, jointly and severally with Kanders & Company, Inc., to indemnify and hold harmless the Company against any and all loss, liability, claims, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by any vendor or other person who is owed money by the Company for services rendered or products sold or contracted for, or by any target business, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Account and only if such a vendor or prospective target business does not execute a valid and enforceable agreement waiving any claims against the Trust Account. The undersigned acknowledges and agrees that there will be no distribution from the Trust Account with respect to any warrants, all rights of which will terminate on the Company’s liquidation.

3. In order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned has agreed, until the earliest of the Company's consummation of a Business Combination, the liquidation of the Company or until such time as the undersigned ceases to be an officer or director of the Company, to present to the Company for its consideration, prior to presentation to any other person or entity, any business opportunity to acquire a privately held operating business, if, and only if (i) the target entity has a fair market value between 80% of the balance in the Trust Account (excluding deferred underwriting discounts and commissions) and $500 million, the target entity's principal business operations are in the healthcare industry and the opportunity is to acquire substantially all of the assets or 50.1% or greater of the voting securities of the target entity or (ii) the target entity's principal business operations are outside of the healthcare industry and the opportunity to acquire such target entity is presented by a third party to the undersigned expressly for consideration by the Company. With respect to all business opportunities, including those described in clause (i), but excluding those described in clause (ii) above, the obligation of the undersigned to present a business opportunity to the Company which may be reasonably required to be presented to the Company under Delaware law is subject to any pre-existing fiduciary or other obligations the undersigned may owe to another entity. The Board of Directors of the Company has adopted resolutions ("Resolutions") renouncing any interest in or expectancy to be presented any business opportunity outside of those described in clauses (i) and (ii) above (as qualified by the immediately preceding sentence) that comes to the attention of any of the Company's officers or non-independent directors, including the undersigned. Neither this section nor the Resolutions may be amended or rescinded in any way except upon prior approval by the holders of a majority of the Company's outstanding shares of common stock.

The undersigned understands that the Company may effect a Business Combination with any entity and agrees that, during the period commencing on the closing of the IPO and extending until the Company has entered into a letter of intent, agreement in principle or definitive agreement regarding the Company’s initial Business Combination, he will not participate in the formation of, or become affiliated as an officer, director or stockholder of, any blank check company with a focus on target businesses in the healthcare industry.

4. The undersigned acknowledges and agrees that the Company will not consummate any Business Combination which involves a company which is affiliated

Related Party and the undersigned shall also be entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination.

6. Neither the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive or accept a finder’s fee or any other compensation in the event the undersigned, any member of the family of the undersigned or any affiliate of the undersigned originates a Business Combination.

7. The undersigned will escrow all of his Founders’ Units (and underlying securities) until one year after the consummation by the Company of a Business Combination subject to the terms of an Escrow Agreement which the Company will enter into with the undersigned and an escrow agent acceptable to the Company.
