		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. 
	 

	 
		 3. 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; provided, however, that nothing
		contained herein shall override a person’s fiduciary obligations to any
		entity with which he is currently directly or indirectly associated or
		affiliated or by whom he is currently employed.
	 

	 
		4. The undersigned acknowledges and agrees
		that the Company will not consummate any Business Combination which involves a
		company which is affiliated with any of the Insiders unless the Company obtains
		an opinion from an independent investment banking firm reasonably acceptable to
		the Representative that the business combination is fair to the Company’s
		stockholders from a financial perspective.
	 

	 
		5. Neither the undersigned, any member of
		the family of the undersigned, nor any affiliate of the undersigned will be
		entitled to receive and will not accept any compensation for services rendered
		to the Company prior to or in connection with the consummation of the Business
		Combination; provided, however, that the undersigned shall be entitled to
		reimbursement from the Company for his 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.
	 

	 
		8. [Intentionally Omitted]
	 

	 
		9. The undersigned agrees to be a Director
		of the Company until the earlier of the consummation by the Company of a
		Business Combination or the liquidation of the Company; provided that nothing
		herein shall be construed as providing a right of the undersigned to any
		position if removed by proper corporate action. The undersigned further agrees
		to sign all documents necessary or in connection with the IPO. The
		undersigned’s biographical information furnished to the Company and the
		Representative and attached hereto as Exhibit A is true and accurate in all
		respects, does not omit any material information with respect to the
		undersigned’s background and contains all of the information required to
		be disclosed pursuant to Item 401 of Regulation S-K, promulgated under the
		Securities Act of 1933. The undersigned’s NASD and Director and Officer
		Questionnaires furnished to the Company and the Representative and annexed as
		Exhibit B hereto are true and accurate in all respects. The undersigned
		represents and warrants that:
	 

	 
		(a) he is not subject to, or a respondent
		in, any legal action for, any injunction, cease-and-desist order or order or
		stipulation to desist or refrain from any act or practice relating to the
		offering of securities in any jurisdiction;
	 

	 
		(b) he has never been convicted of or
		pleaded guilty to any crime (i) involving any fraud or (ii) relating to any
		financial transaction or handling of funds of another person, or (iii)

		defendant in any such criminal proceeding; and
	 

	 
		(c) he has never been suspended or expelled
		from membership in any securities or commodities exchange or association or had
		a securities or commodities license or registration denied, suspended or
		revoked.
	 

	 
		10. The undersigned has full right and
		power, without violating any agreement by which he is bound, to enter into this
		letter agreement and to serve as a Director of the Company and hereby consents
		to being named in the registration statement as such.
	 

	 
		 
	 



	 
	 

	 

	 
		11. The undersigned hereby waives his right
		to exercise conversion rights with respect to any shares of the Company’s
		common stock owned or to be owned by the undersigned, directly or indirectly,
		and agrees that he will not seek conversion with respect to such shares in
		connection with any vote to approve a Business Combination.
	 

	 
		12. The undersigned hereby agrees to not
		propose, or vote in favor of, an amendment to the Company’s Certificate of
		Incorporation to extend the period of time in which the Company must consummate

		before stockholders, the undersigned hereby agrees to vote against such
		proposal except in connection with a Business Combination to give the Company
		perpetual existence. This paragraph may not be modified or amended under any
		circumstances.

		14. This letter agreement shall be governed
		by and construed and enforced in accordance with the laws of the State of New
		York, without giving effect to conflicts of law principles that would result in
		the application of the substantive laws of another jurisdiction. The
		undersigned hereby (i) agrees that any action, proceeding or claim arising out
		of or relating in any way to this letter agreement (a
		“Proceeding”) shall be brought and enforced in the
		courts of the State of New York of the United States of America for the
		Southern District of New York, and irrevocably submits to such jurisdiction,
		which jurisdiction shall be exclusive and (ii) waives any objection to such
		exclusive jurisdiction and that such courts represent an inconvenient forum.
		
	 

	 
		15. The undersigned acknowledges and
		understands that the Underwriters and the Company will rely upon the
		agreements, representations and warranties set forth herein in proceeding with
		the IPO. Nothing contained herein shall be deemed to render the Underwriters a
		representative of, or a fiduciary with respect to, the Company, its
		stockholders or any creditor or vendor of the Company with respect to the
		subject matter hereof. 
	 

	 
		16. This letter agreement shall be binding
		on the undersigned and such person’s respective successors, heirs,
		personal representatives and assigns. This letter agreement shall terminate on
		the earlier of (i) the expiration of the longest applicable lock-up period

		such termination shall not relieve the undersigned from liability for any
		breach of this agreement prior to its termination.

		stock exchange, asset acquisition or other similar business combination with an

		Representative and its legal representatives or agents (including any
		investigative search firm retained by the Representative) any information they
		may have about the undersigned’s background and finances
		(“Information”), purely for the purposes of the
		Company’s IPO (and shall thereafter hold such information confidential).
