Re:

Initial Public Offering

Gentlemen:

This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between Chardan Healthcare Acquisition Corp., a Delaware corporation (the “Company”) and Chardan Capital Markets LLC, as representative (the “Representative”) of the 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 Common Stock of the Company, par value $0.001 per share (the “Common Stock”), and one warrant, with each warrant being exercisable to purchase one-half of one share of Common Stock at a price of $11.50 per full share (“Warrant”). Certain capitalized terms used herein are defined in paragraph 14 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 shareholder 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 shareholders of a Business Combination, the undersigned will vote all shares of Common Stock beneficially owned by him, her or it, whether acquired before, in or after the IPO, in favor of such Business Combination.

2. (a) In the event that the Company fails to consummate a Business Combination within 24 months from the closing of the Company’s IPO, the undersigned shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of IPO Shares and (ii) cause the Company to liquidate as soon as reasonably practicable.

(b) The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net assets of the Company as a result of such liquidation with respect to his, her or its Insider Shares, [Private Warrants] (and the underlying 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 Fund for any reason whatsoever. [The undersigned acknowledges and agrees that there will be no distribution from the Trust Fund with respect to any Common Stock underlying the Private Warrants, all rights of which will terminate on the Company’s liquidation.]

[ (c) In the event of the liquidation of the Trust Fund, the undersigned agrees 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) 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, 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 Fund; provided, that such indemnity shall not apply if such vendor or other person has executed an agreement waiving any claims against the Trust Fund. ]¹

[ (d) In the event that the Company does not consummate a Business Combination and must liquidate and its remaining net assets are insufficient to complete such liquidation, the undersigned agrees to advance such funds necessary to complete such liquidation and agrees not to seek repayment for such expenses.]²

3. The undersigned will escrow all of his, her or its Insider Shares pursuant to the terms of a Stock Escrow Agreement which the Company will enter into with the undersigned and an escrow agent acceptable to the Company.

[4. The undersigned agrees that until the Company consummates a Business Combination, the undersigned’s Private Warrants will be subject to the transfer restrictions described in the Subscription Agreement relating to the undersigned’s Private Warrants.]³

5. In order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned agrees to present to the Company for its consideration, prior to presentation to any other person or entity, any suitable opportunity to acquire a target business, until the earlier of the consummation by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations the undersigned might have.

6. The undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders of the Company or their affiliates, including any company that is a portfolio company of, or otherwise affiliated with, or has received financial investment from, an entity with which any Insider or their affiliates is affiliated, such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm that such Business Combination is fair to the Company’s unaffiliated shareholders from a financial point of view.

7. 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 or other cash payment prior to, or for services rendered in connection with, the consummation of the Business Combination. Notwithstanding the foregoing, the undersigned and any affiliate of the undersigned shall be entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with identifying, investigating and consummating a Business Combination.

8. 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.
