 Re: Initial Public Offering 
  
 Ladies and Gentlemen: 
  
 The undersigned officer, director and security holder of Good Harbor Partners Acquisition Corp. (the “Company”),
in consideration of HCFP/Brenner Securities LLC’s (“Brenner”) willingness to underwrite an initial public offering of the securities of the Company (the “IPO”) and embarking on the IPO process, hereby agrees as follows
(certain capitalized terms used herein are defined in paragraph 11 hereof): 
  
 1. In the event that the Company fails to consummate a Business Combination within 18 months from the effective date (“Effective Date”) of the registration statement relating to the IPO (or 24 months under
the circumstances described in the prospectus relating to the IPO), the undersigned will take all reasonable actions within his power to (i) cause the Trust Fund to be liquidated and distributed to the holders of the shares of Class B common stock
sold in the Company’s IPO and (ii) liquidate as soon as reasonably practicable. The undersigned waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund as a result of such liquidation with
respect to his Insider Securities (each a “Claim”) and hereby waives any Claim he 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 agrees to indemnify and hold harmless the Company, severally, pro rata with Richard Clarke, John Tritak, Jack Mallon, Thomas J. Colatosti, Roger Cressey and Brian Stafford (together with the undersigned the
“Indemnifiers”), based on the percentage of Insider Securities directly or indirectly beneficially owned by the Indemnifiers prior to the IPO, 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 by any target business, only in the event that such vendor, other person or target business did not execute an agreement waiving any
right, title, interest or claim of any kind in or to any amounts held in the Trust Fund, and only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount in the Trust Fund.

2. 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 an operating business, until the earlier of the consummation by the Company of a Business Combination, the liquidation of the Trust Fund
or until such time as the undersigned ceases to be an officer or director of the Company, subject to any pre-existing fiduciary obligations the undersigned might have. 
  
 3. 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 Brenner that the business combination is fair to the Company’s stockholders from a
financial perspective. 
  
 4. Neither the undersigned, any member
of the family of the undersigned, nor any affiliate (“Affiliate”) of the undersigned will be entitled to receive and will not accept any compensation or fees of any kind, including finder’s and consulting fees, prior to, or for
services they rendered in order to effectuate, the Business Combination. 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. 
  
 5. Neither the undersigned, any member of the
family of the undersigned, or 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. 
  
 6. The
undersigned agrees not to sell any of his Insider Securities until the Company’s completion of a Business Combination. 
  
 7. The undersigned has agreed to vote any shares of Class B common stock it holds or hereafter acquires in favor of any proposed Business Combination
approved by the Company’s Board of Directors. 
  
 8. The
undersigned agrees to be the Chief Executive Officer, Secretary and a member of the Board of Directors of the Company until the earlier of the consummation by the Company of a Business Combination or the distribution of the Trust Fund. The
undersigned’s biographical information furnished to the Company and Brenner 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 Section 401 of Regulation S-K, promulgated under the Securities Act of 1933. The undersigned’s Questionnaire furnished to the Company and Brenner and annexed as Exhibit B
