Dear Sirs:

1. INTRODUCTORY. Aerie Pharmaceuticals, Inc., a Delaware corporation (the “Company”), proposes to sell, pursuant to the terms of this Agreement, to the several underwriters named in Schedule A hereto (the “Underwriters,” or, each, an “Underwriter”), an aggregate of 1,266,892 shares of common stock, $0.001 par value (the “Common Stock”), of the Company. The aggregate of 1,266,892 shares of Common Stock so proposed to be sold is hereinafter referred to as the “Firm Stock.” The Company also proposes to sell to the Underwriters, upon the terms and conditions set forth in Section 3 hereof, up to an additional 190,033 shares of Common Stock (the “Optional Stock”). The Firm Stock and the Optional Stock are hereinafter collectively referred to as the “Stock.” Cantor Xxxxxxxxxx & Co. is acting as representative of the several Underwriters and in such capacity is hereinafter referred to as the “Representative.”

2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to the several Underwriters, as of the date hereof and as of the Closing Date or the Option Closing Date (each as defined below), as the case may be, and agrees with the several Underwriters, that:

(a) Compliance with Registration Requirements. A registration statement of the Company on Form S-3 (File No. 333-213643) (including all pre-effective amendments thereto and all post-effective amendments thereto filed before execution of this Agreement, the “Initial Registration Statement”) in respect of the Stock was filed with the Securities and Exchange Commission (the “Commission”) on September 15, 2016 pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). The Initial Registration Statement and any post-effective amendment thereto, each in the form heretofore delivered to you, became effective upon filing in such form and meet the requirements of the Securities Act and the rules and regulations of the Commission thereunder (the “Rules and Regulations”) in all material respects. At the time the Initial Registration Statement originally became effective, and thereafter, if applicable, at the time the Company’s most recent Annual Report on Form 10-K was filed with the Commission, as well as at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) made any offer relating to the Stock in reliance on the exemption of Rule 163 under the Securities Act, the Company was a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act. The Initial Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 under the Securities Act, and became effective on September 15, 2016. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the Company’s use of the automatic shelf registration form. Other than (i) the Initial Registration Statement, (ii) a registration statement, if any, increasing the size of the offering filed pursuant to Rule 462(b) under the Securities Act and the Rules and Regulations (a “Rule 462(b) Registration Statement”), (iii) any Preliminary Prospectus (as defined below), (iv) the Prospectus (as defined below) contemplated by this Agreement to be filed pursuant to Rule 424(b) of the Rules and Regulations in accordance with Section 4(a) hereof and (v) any Issuer Free Writing Prospectus (as defined below), no other document with respect to the offer and sale of the Stock has heretofore been filed with the Commission. No stop order suspending the effectiveness of the Initial Registration Statement, any post-effective amendment thereto or the Rule 462(b) Registration Statement, if any, has been issued and no proceeding for that purpose or pursuant to Section 8A of the Securities Act has been initiated or, to the

knowledge of the Company, threatened by the Commission. The Base Prospectus (as defined below), as supplemented by any preliminary prospectus relating to the offer and sale of the Stock filed with the Commission pursuant to Rule 424 of the Rules and Regulations is hereinafter called a “Preliminary Prospectus.” The various parts of the Initial Registration Statement and the Rule 462(b) Registration Statement, if any, in each case including all exhibits thereto and including (i) the information contained in the Prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations and deemed by virtue of Rule 430A, 430B or 430C of the Rules and Regulations to be part of the Initial Registration Statement at the time specified in the applicable Rule and (ii) the documents incorporated by reference in the Rule 462(b) Registration Statement at the time the Rule 462(b) Registration Statement became effective, are hereinafter collectively called the “Registration Statements.” The base prospectus included in the Initial Registration Statement at the time of effectiveness thereof (the “Base Prospectus”), as supplemented by the final prospectus supplement relating to the offer and sale of the Stock, in the form filed pursuant to and within the time limits described in Rule 424(b) of the Rules and Regulations, is hereinafter called the “Prospectus.”

Any reference herein to any Registration Statement, Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, to the extent such information has not been superseded or modified in accordance with Rule 412 of the Rules and Regulations. Any reference to any amendment or supplement to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such Preliminary Prospectus or the Prospectus under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and deemed incorporated by reference in such Preliminary Prospectus or Prospectus, as the case may be. Any reference to (i) any Registration Statement shall be deemed to refer to and include any document filed under the Exchange Act that is deemed incorporated by reference in such Registration Statement, including the Annual Report on Form 10-K of the last completed fiscal year of the Company filed under Section 13(a) or 15(d) of the Exchange Act on or prior to the date hereof and (ii) the effective date of such Registration Statement shall be deemed to refer to and include the date such Registration Statement became effective, and, if later the date such Form 10-K was so filed. Any reference to any amendment to the Registration Statements shall be deemed to refer to and include any document filed under the Exchange Act that is deemed incorporated by reference in such Registration Statement, including any annual report of the Company filed pursuant to Section 13(a) or 15(d) of the Exchange Act after the date of this Agreement that is incorporated by reference in the Registration Statement.

(b) Disclosure. As of the Applicable Time (as defined below) and as of the Closing Date or the Option Closing Date, as the case may be, none of (i) the General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time, the Pricing Prospectus (as defined below) and the information included on Schedule B hereto, all considered together (collectively, the “General Disclosure Package”), (ii) any individual Limited Use Free Writing Prospectus (as defined below), or (iii) any “bona fide electronic road show” (as defined in Rule 433(h)(5) of the Rules and Regulations), in each case when considered together with the General Disclosure Package, included or will include any untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to information contained or omitted, in reliance upon, and in conformity with, written information furnished to the Company through the Representative by or on behalf of any Underwriter specifically for inclusion therein, which information the parties hereto agree is limited to the Underwriters’ Information (as defined in Section 17).

The Company has requisite corporate power to conduct its business as described in the Registration Statements, the General Disclosure Package and the Prospectus. The Company is duly qualified to transact business and is in good standing in all jurisdictions in which the conduct of its business requires such qualification; except where the failure to be so qualified or to be in good standing would not, individually or in the aggregate, (i) have a material adverse effect on the condition (financial or otherwise), properties, assets, liabilities, operations, earnings, business or prospects of the Company taken as a whole, whether or not arising from transactions in the ordinary course of business, (ii) prevent or materially interfere with consummation of the transactions contemplated hereby or (iii) prevent the Stock from being accepted for listing on, or resulting in the delisting of the Stock from, the Nasdaq Global Market (the “Exchange”) (the occurrence of any of the foregoing events in clauses (i), (ii) or (iii) being a “Material Adverse Effect”).

Neither the filing of the Registration Statements nor the offering or sale of the Firm Stock or the Optional Stock, if any, as contemplated by this Agreement gives rise to any rights for or relating to the registration of any shares of Common Stock, other than such rights that have been waived or otherwise satisfied and disclosed in the Registration Statements, the General Disclosure Package and the Prospectus.

The execution and delivery of this Agreement and the consummation of the transactions herein contemplated and the performance by the Company of its obligations hereunder will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, (x) any contract, indenture, mortgage, deed of trust or other agreement or instrument to which the Company is a party, (y) the Charter or bylaws of the Company or (z) any order, rule or regulation applicable to the Company of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction over the Company, except in the case of clauses (x) and (z) where such conflict, breach or default would not individually or in the aggregate cause a Material Adverse Effect.

(x) No Consents Required. No approval, consent, order, authorization or filing by or with any regulatory, administrative or other governmental body is necessary in connection with the execution and delivery by the Company of this Agreement and the consummation of the transactions herein contemplated (except such as have been already obtained or such additional steps as may be required by the Commission, the Financial Industry Regulatory Authority, Inc.

There is no claim, proceeding or controversy, pending or, to the knowledge of the Company, threatened, involving the status of or sanctions under any of the Permits which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect. The Company has fulfilled and performed all of its material obligations with respect to the Permits.

(z) Certain Market Activities. Neither the Company, nor to the Company’s knowledge, any of its affiliates, has taken or may take, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of the shares of Common Stock to facilitate the sale or resale of the Stock.

(c) If at any time when a prospectus relating to the Stock is required to be delivered (or in lieu thereof, the notice referred to in Rule 173(a) of the Rules and Regulations): (i) any event occurs or condition exists as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact, or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made when the Prospectus is delivered (or in lieu thereof, the notice referred to in Rule 173(a) of the Rules and Regulations), not misleading, or if it is necessary at any time to amend or supplement any Registration Statement or the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Representative thereof or (ii) in the opinion of the Representative it is necessary to amend or supplement any Registration Statement or the Prospectus to comply with applicable law or to file under the Exchange Act any document incorporated by reference in the Prospectus to comply with applicable law, then in the case of clauses (i) and (ii), upon the request of the Representative, the Company will prepare an appropriate amendment or supplement or upon the Representative’s request make an appropriate filing pursuant to Section 13 or 14 of the Exchange Act in form and substance reasonably satisfactory to the Representative that will correct such statement or omission or effect such compliance and will use its reasonable best efforts to have any amendment to any Registration Statement declared effective as soon as possible. The Company will furnish without charge to each Underwriter and to any dealer in securities as many copies as the Representative may from time to time reasonably request of such amendment or supplement; provided that the Company shall not be required to furnish any amendment or supplement (other than an amendment or supplement to the Prospectus) to the extent such amendment or supplement is available on XXXXX.

The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company through the Representative by or on behalf of any Underwriter specifically for inclusion therein, which information the parties hereto agree is limited to the Underwriters’ Information (as defined in Section 17).

7. INDEMNIFICATION AND CONTRIBUTION.

(a) Company Indemnification. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates and their respective partners, members, directors, officers, employees and agents and each person, if any, who controls any Underwriter or any affiliate within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statements (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any related Issuer Free Writing Prospectus, any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that any such settlement is effected with the written consent of the Company, which consent shall not unreasonably be delayed or withheld; and

(iii) against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, whether or not a party, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made solely in reliance upon and in conformity with written information furnished to the Company through the Representative by or on behalf of any Underwriter expressly for use in the Registration Statements (or any amendment thereto), or in any related Issuer Free Writing Prospectus, any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Underwriter Indemnification. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company and its directors and each officer of the Company who signed the Registration Statements, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 7(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statements (or any amendments thereto), any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information furnished to the Company in writing through the Representative by or on behalf of that Underwriter expressly for use therein, which information the parties hereto agree is limited to the Underwriters’ Information (as defined in Section 17).

(c) Procedure. Any party that proposes to assert the right to be indemnified under this Section 7 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 7, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this Section 7 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 7 unless, and only to the

extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any other legal expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel to assume the defense of such action or counsel satisfactory to the indemnified party, in each case, within a reasonable time after receiving notice of the commencement of the action; in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction (plus local counsel) at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred and after the indemnifying party receives a written notice relating to the fees, disbursements and other charges in reasonable detail. An indemnifying party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 7 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (1) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (2) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) [Reserved].

(e) Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 7 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Underwriters, the Company and the Underwriters will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriters, such as persons who control the Company within the meaning of the Securities Act, officers of the Company who signed the Registration Statements and directors of the Company, who also may be liable for contribution) to which the Company and the Underwriters may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand. The relative benefits received by the Company on the one hand and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the sale of the Stock (before deducting expenses) received by the Company bear to the total compensation received by the Underwriters (before deducting expenses) from the sale of Stock on behalf of the Company. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such

proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, with respect to the statements or omission that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(e) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section 7(e) shall be deemed to include, for the purpose of this Section 7(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with Section 7(c) hereof. Notwithstanding the foregoing provisions of this Section 7(e), no Underwriter shall be required to contribute any amount in excess of the compensation received by such Underwriter under this Agreement and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7(e), any person who controls a party to this Agreement within the meaning of the Securities Act, and any officers, directors, partners, employees or agents of the Underwriters, will have the same rights to contribution as that party, and each director of the Company and each officer of the Company who signed the Registration Statements will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 7(e), will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 7(e) except to the extent that the failure to so notify such other party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section 7(c) hereof, no party will be liable for contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section 7(c) hereof.

8. TERMINATION. The obligations of the Underwriters hereunder may be terminated by the Representative, in its absolute discretion by notice given to the Company prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 6(j) or 6(k) have occurred.

9. REIMBURSEMENT OF UNDERWRITERS’ EXPENSES. Notwithstanding anything to the contrary in this Agreement, if (a) this Agreement shall have been terminated pursuant to Section 8, (b) the Company shall fail to tender the Stock for delivery to the Underwriters for any reason not permitted under this Agreement or (c) the sale of the Stock is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of the refusal, inability or failure on the part of the Company to perform in all material respects any agreement herein or to satisfy any condition or to comply with the provisions hereof, then in addition to the payment of amounts in accordance with Section 5, the Company shall, pro rata based on the number of shares of Firm Stock and Optional Stock it agreed to sell hereunder, reimburse the Underwriters for the reasonable and documented out-of-pocket fees and expenses of Underwriters’ counsel (limited to one counsel) and for such other reasonable and documented out-of-pocket expenses as shall have been reasonably incurred by them in connection with this Agreement and the proposed purchase of the Stock, including, without limitation, travel and lodging expenses of the Underwriters, and upon demand the Company shall pay the full amount thereof to the Representative; provided that if this Agreement is terminated by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of expenses to the extent incurred by such defaulting Underwriter provided further that the foregoing shall not limit any reimbursement obligation of the Company to any non-defaulting Underwriter under this Section 9.

10. SUBSTITUTION OF UNDERWRITERS. If any Underwriter or Underwriters shall default in its or their obligations to purchase shares of Stock hereunder on the Closing Date or the Option Closing Date, as the case may be, and the aggregate number of shares which such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed ten percent (10%) of the total number of shares to be purchased by all Underwriters on such Closing Date or Option Closing Date, as the case may be, the other Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the shares which such defaulting Underwriter or Underwriters agreed but failed to purchase on such Closing Date or Option Closing Date, as the case may be. If any Underwriter or Underwriters shall so default and the aggregate number of shares with respect to which such default or defaults occur is more than ten percent (10%) of the total number of shares to be purchased by all Underwriters on such Closing Date or Option Closing Date, as the case may be, and arrangements satisfactory to the Representative and the Company for the purchase of such shares by other persons are not made within forty-eight (48) hours after such default, this Agreement shall terminate.

If the remaining Underwriters or substituted Underwriters are required hereby or agree to take up all or part of the shares of Stock of a defaulting Underwriter or Underwriters on such Closing Date or Option Closing Date, as the case may be, as provided in this Section 10, (i) the Company shall have the right to postpone such Closing Date or Option Closing Date, as the case may be, for a period of not more than five (5) full business days in order that the Company may effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees promptly to file any amendments to the Registration Statement or supplements to the Prospectus which may thereby be made necessary, and (ii) the respective numbers of shares to be purchased by the remaining Underwriters or substituted Underwriters shall be taken as the basis of their underwriting obligation for all purposes of this Agreement. Nothing herein contained shall relieve any defaulting Underwriter of its liability to the Company or the other Underwriters for damages occasioned by its default hereunder. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of any non-defaulting Underwriter or the Company, except that the representations, warranties, covenants, indemnities, agreements and other statements set forth in Section 2, the obligations with respect to expenses to be paid or reimbursed pursuant to Sections 5 and 9 and the provisions of Section 7 and Sections 12 through 21, inclusive, shall not terminate and shall remain in full force and effect.

11. ABSENCE OF FIDUCIARY RELATIONSHIP. The Company acknowledges and agrees that:

(a) each Underwriter’s responsibility to the Company is solely contractual in nature, the Representative has been retained solely to act as underwriter in connection with the sale of the Stock and no fiduciary, advisory or agency relationship between the Company and the Representative has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Representative has advised or is advising the Company on other matters;

(b) the price of the Stock set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Representative and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) it has been advised that the Representative and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Representative has no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) it waives, to the fullest extent permitted by law, any claims it may have against the Representative for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representative shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including shareholders, employees or creditors of the Company.

12. SUCCESSORS; PERSONS ENTITLED TO BENEFIT OF AGREEMENT.

Re:	Aerie Pharmaceuticals, Inc. – Registration Statement on Form S-3 for Shares of Common Stock

Ladies and Gentlemen:

This agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) between Aerie Pharmaceuticals, Inc., a Delaware corporation (the “Company”), and Cantor Xxxxxxxxxx & Co. (“Cantor”), as represetative to the several underwriters listed in Schedule A thereto (collectively, the “Underwriters”) relating to the proposed public offering of shares of the common stock, par value $0.001 per share, of the Company (the “Common Stock”).

In order to induce you and the other Underwriters to enter into the Underwriting Agreement, and in light of the benefits that the offering of Common Stock will confer upon the undersigned in its capacity as a securityholder and/or an officer and/or director of the Company, and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with Cantor that, during the period beginning on the date hereof through and including the date that is the 60^th day after the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of Cantor, directly or indirectly, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, or publicly announce the intention to otherwise dispose of, any shares of Common Stock (including, without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations promulgated under the Securities Exchange Act of 1934, as the same may be amended or supplemented from time to time (the “Exchange Act”)) or securities convertible into or exercisable or exchangeable for Common Stock, (ii) enter into any swap, hedge or similar agreement or arrangement that transfers in whole or in part, the economic risk of ownership of the Common Stock or securities convertible into or exercisable or exchangeable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or (iii) engage in any short selling of Common Stock.

The restrictions set forth in the immediately preceding paragraph shall not apply to:

(1) if the undersigned is a natural person, any transfers made by the undersigned (a) as a bona fide gift to any member of the immediate family (as defined below) of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned or members of the undersigned’s immediate family, (b) by will or intestate succession upon the death of the undersigned or (c) as a bona fide gift to a charity, non-profit organization or educational institution,

(2) if the undersigned is a corporation, partnership, limited liability company or other business entity, any transfers to any shareholder, partner or member of, or owner of a similar equity interest in, the undersigned, as the case may be, if, in any such case, such transfer is not for value,

(3) if the undersigned is a corporation, partnership, limited liability company or other business entity, any transfer made by the undersigned (a) in connection with the sale or other bona fide transfer in a single transaction of all or substantially all of the undersigned’s capital stock, partnership interests, membership interests or other similar equity interests, as the case may be, or all or substantially all of the undersigned’s assets, in any such case not undertaken for the purpose of avoiding the restrictions imposed by this agreement or (b) to another corporation, partnership, limited liability company or other business entity so long as the transferee is an affiliate (as defined below) of the undersigned and such transfer is not for value,

(4) the transfer or sale of any shares of Common Stock or other securities pursuant to any contract, instruction or plan meeting the requirements of Rule 10b5-1 under the Exchange Act, that has been entered into by the undersigned (or a member of the undersigned’s immediate family) prior to the date hereof, and

(5) any transfer pursuant to an order of a court or regulatory agency or by operation of law;

provided, however, that (A) in the case of any transfer described in clause (1)(a), 1(c), (2) or (3) above, prior to the expiration of the Lock-Up Period, no public disclosure or filing under Section 16(a) of the Exchange Act shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Common Stock in connection with such transfer, (B) in the case of any transfer described in clause (1)(a), (1)(b), (2) or (3) above, it shall be a condition to the transfer that the transferee executes and delivers to Cantor, acting on behalf of the Underwriters, not later than one business day (as defined in the Underwriting Agreement) prior to such transfer, a written agreement, in substantially the form of this agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the undersigned and not to the immediate family of the transferee) and otherwise reasonably satisfactory in form and substance to Cantor, and (C) in the case of any transfer described in clause (4) above, if the undersigned is required to file a report under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock during the Lock-Up Period, the undersigned shall include a statement in such report to the effect that such transfer is being made pursuant to a contract, instruction or plan meeting the requirements of Rule 10b5-1 under the Exchange Act.

Notwithstanding the foregoing, the restrictions described herein shall not apply to (A) the exercise of any options or warrants to purchase shares of Common Stock or the vesting of any other equity-based awards, including on a “cashless” or “net exercise” basis and/or to satisfy withholding obligations in connection with the exercise of options or warrants to purchase shares of Common Stock or the vesting of any other equity-based awards; provided that in any such case the shares of Common Stock issued upon exercise or vesting shall remain subject to the provisions of this agreement and, prior to the expiration of the Lock-Up Period, no public disclosure or filing under Section 16(a) of the Exchange Act shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Common Stock in connection with such exercise or vesting, except that a filing under Section 16 of the Exchange Act may be made by the undersigned if the footnotes thereto clearly indicate (1) that no shares were sold by the reporting person and that the shares received upon exercise of the option or warrant or vesting of the equity-based award are subject to a lock-up agreement with Cantor and (2) the disposition of any shares was made solely to the Company or (B) the entering into by the undersigned of a trading plan (a “New Plan”) meeting the requirements of Rule 10b5-1 under the Exchange Act, relating to the sale of shares of Common Stock or other securities, if then permitted by the Company and applicable law; provided, that the shares of Common Stock or other securities subject to such New Plan shall not be sold during the Lock-Up Period.

For purposes of this agreement, “immediate family” shall mean a spouse, domestic partner, child, grandchild or other lineal descendant (including by adoption), father, mother, brother or sister of the undersigned; and “affiliate” shall have the meaning set forth in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”).

The undersigned further agrees that (i) it will not, during the Lock-Up Period, make any demand or request for or exercise any right with respect to the registration under the Securities Act, of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, and (ii) the Company may, with respect to any Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock owned or held (of record or beneficially) by the undersigned, cause the transfer agent or other registrar to enter stop transfer instructions and implement stop transfer procedures with respect to such securities during the Lock-Up Period.

It is understood that, if (i) the Company notifies Cantor in writing that it does not intend to proceed with the offering of Common Stock contemplated by the Underwriting Agreement; (ii) the Underwriting Agreement relating to the offering of Common Stock is not executed on or before January 31, 2018; or (iii) the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated for any reason prior to payment for and delivery of the shares of Common Stock to be sold thereunder, this agreement shall immediately terminate and the undersigned shall automatically be released from all of his, her or its obligations under this agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement and that this agreement has been duly authorized (if the undersigned is not a natural person), executed and delivered by the undersigned and is a valid and binding agreement of the undersigned (except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws). This agreement and all authority herein conferred are irrevocable and shall survive the death or incapacity of the undersigned (if a natural person) and shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

This agreement shall be governed by and construed in accordance with the law of the State of New York, without regard to the conflict of laws principles thereof.

The undersigned acknowledges that whether or not any public offering of Common Stock actually occurs depends on a number of factors, including market conditions.
