	Employee’s Last Name	  	First Name	  	Middle Initial

  
 I, the undersigned,
recognize that in my position with the Company I will be performing a highly responsible role in a very competitive industry. Because of the injury that might accrue to the Company through my association with a competitor of the Company, combined
with my privileged access to the Company’s proprietary information, I understand that it is important that the Company protect itself. I, further, recognize that execution of this Agreement is an express condition of my employment. 

 
 In consideration of my employment, continued employment, promotion or
increase in compensation by the Company, I hereby agree as follows: 
  
 1. Definition. For the purposes of this Agreement, the “Company” means and includes Achillion Pharmaceuticals, Inc. and all of its existing, past or future parents, subsidiaries and affiliates.

  
 2. Best Efforts; Reasonableness of
Restrictions. 
  
 (a) During the period of my
employment with the Company, I shall devote my full time and best efforts to the business of the Company and I shall neither pursue any business opportunity outside the Company nor take any position with any organization other than the Company
without the approval of a majority of the disinterested members of the Company’s Board of Directors. 
  
 (b) I acknowledge and agree that (i) by virtue of my acquiring knowledge of the Company’s valuable trade secrets and
confidential information concerning the names, specialized needs, concerns, and characteristics of the Company’s customers and other aspects of the Company’s sales, marketing, pricing, and promotional activities learned or developed in the
course of my employment at the Company, and (ii) in recognition of the worldwide market for the Company’s services and technology, the restrictions contained in Sections 3 and 4 hereof are reasonable in all respects to protect the
Company’s investment in my training and development, to protect the Company from unfair competition, and to protect the good will and other business interests of the Company. 
  
 3. Covenant Not to Compete. 
  
 (a) I shall not during my employment with the Company and for a period of one year thereafter directly or
indirectly enter into, participate in or engage in a business or the solicitation of any business which is, directly or indirectly, in competition or proposes to be in competition with the business of the Company (which as of the date hereof is the
discovery, development and commercialization of small molecule drugs that combat resistance in infectious diseases, particularly those caused by hepatitis B virus, hepatitis C virus or HIV, including research and development relating to zinc finger
drug development technology and elvucitabine, as an individual on my own account, as a 

  

 Page 1 of 5 








 
stockholder, principal, partner or joint venturer, as the owner of an interest in, or as a director or officer of, any business or entity, as an employee,
agent, salesman, contractor or consultant of any person, business or entity, or otherwise, except that nothing contained herein will preclude me from purchasing or owning securities of any such business or entity if such securities are publicly
traded and my holdings thereof do not exceed one percent (1%) of the issued and outstanding securities of any class of securities of such business or entity. Notwithstanding the foregoing and any other provision of this Agreement, Employee will
not be restrained following his employment with the Company from participating in or engaging in a business or the solicitation of any business as an individual, employee, consultant, stockholder, principal, partner or joint venturer, owner,
director, officer of any business or entity so long as employee does not participate or engage in activities related to discovery, development and commercialization of small molecule drugs that combat resistance in infectious diseases, particularly
those caused by hepatitis B virus, hepatitis C virus or HIV, including research and development relating to zinc finger drug development technology and elvucitabine. 
  
 (b) I will not, at any time during or after the termination of my employment with the Company, interfere or
attempt to interfere with, the relationship of the Company with any person or entity which at any time during my employment with the Company was an employee, licensee, sales agent or sales representative (or employee thereof), or customer, potential
customer or vendor of, or supplier or licensor to, or in the habit of dealing with, the Company, as an individual on my own account, as a partner or joint venturer, as the owner of an interest in, or as a director or officer of, any entity, as an
employee, agent, salesman, contractor or consultant of any person or entity, or otherwise. 
  
 4. Covenant Not to Solicit. 
  
 (a) I will not during my employment with the Company and for a period of one year thereafter solicit, divert or appropriate, or attempt to
solicit, divert or appropriate, the business of any customer or potential customer of the Company as an individual on my own account, as a stockholder, principal, partner or joint venturer, as the owner of an interest in, or as a director or officer
of, any entity, as an employee, agent, salesman, contractor or consultant of any person or entity, or otherwise.

with the Company has terminated within six (6) months prior to or after my termination with the Company, to leave the Company’s employ, terminate his or its association with the Company, or otherwise interfere with the relationship of the

 5. Severability and Interpretation. I agree that each provision, subpart and
clause herein shall be treated as separate and independent clauses. In the event that any provision, subpart and/or clause of this Agreement is held invalid by a court of competent jurisdiction, the remaining provisions shall nonetheless be
enforceable according to their terms. Further, in the event that any provision, subpart and/or clause is held to be overbroad as written, such provision, subpart and/or clause shall be deemed amended to narrow its application to the extent necessary
to make the provision enforceable according to applicable law and enforced as amended. 
  
 6. Waiver. The Company’s waiver or failure to enforce the terms of this Agreement or any similar agreement in one instance
shall not constitute a waiver of its rights hereunder with respect to other violations of this or any other agreement. In addition, any amendment to or modification of this Agreement or any waiver of any provision hereof must be in writing and
signed by the Company. 
  
 7. Acquiescence in
Injunction. I understand that if I violate any provision of this Agreement the Company will be irreparably harmful and will have no adequate remedy at law. The Company shall have the right, in addition to any other rights it may have, to obtain
in any court of competent jurisdiction injunctive relief to restrain any breach or threatened breach of, or otherwise to specifically enforce, this Agreement. I hereby agree that if I act in violation of any provision hereof, the number of days that
I am in such violation will be added to the one year period specified in Sections 3 and 4 hereof. 
  
 8. No Conflicting Agreements: Disclosure to Future Employers. I represent and warrant that I have not previously assumed any
obligations inconsistent with those of this Agreement. I further represent and warrant that I am in compliance with, and my employment by the Company will not result in any violation of, any obligations previously assumed by me to any third party
with respect to non-competition. I have not entered into, and I will not enter into, any agreement either written or oral in conflict herewith. I will provide, and the Company, in its discretion, may similarly provide, a copy of the covenants
contained in this Agreement to any business or enterprise which I may directly or indirectly own, manage, operate, finance, join, control or in which I may participate in the ownership, management, operation, financing, or control, or with which I
may be connected as an officer, director, employee, partner, principal, agent, representative, consultant or otherwise. 
  
 9. Governing Law. This Agreement and any disputes arising under or in connection with it shall be governed by the laws of the State
of Connecticut, without giving effect to the principles of conflict of laws of such state. I hereby submit for the sole purpose of this Agreement and any dispute arising under or in connection with it to the jurisdiction of the courts located in the
State of Connecticut and any courts of appeal therefrom, and hereby waive any objection (on the grounds of lack of jurisdiction or forum non conveniens or otherwise) to the exercise of such jurisdiction over me by any such
courts. 
  
 10. Notice. Any notice which
the Company is required or may desire to give to me shall be given to me by personal delivery or registered or certified mail, return receipt requested, addressed to me at the address of record with the Company, or at such other place as I may from
time to time designate in writing. Any notice which I am required or may desire to 

  

 Page 3 of 5 








 
give to the Company hereunder shall be given by personal delivery or by registered or certified mail, return receipt requested, addressed to the Company at
its principal office, or at such other office as the Company may from time to time designate in writing. The date of personal delivery or the dates of mailing any such notice shall be deemed to be the date of delivery thereof. 
  
 11. Complete Agreement; Amendments: Prior Agreements:
Employment-at-Will. The foregoing is the entire agreement of the parties with respect to the subject matter hereof and may not be amended, supplemented, canceled or discharged except by written instrument executed by both parties hereto. This
Agreement supersedes any and all prior agreements between the Company and me with respect to the matters covered hereby; provided, however, that in the event of conflict between a provision of this Agreement and a provision of the Nondisclosure and
Assignment of Inventions Agreement, dated as of the date hereof, by and between the Company and me, the provision most favorable to the Company shall govern. Nothing herein is intended to alter my at-will employment. The Company and I understand and
agree that my employment at the Company is at-will and is not for any specified term and that either the Company or I may terminate the employment relationship with or without cause at any time, and that Sections 3 and 4 of this Agreement shall
survive any such termination. 
  
 12.
Miscellaneous. I agree that the provisions of this Agreement shall be binding on my heirs, assigns, executors, administrators and other legal representatives, and may be transferred by the Company to its successors and assigns. This Agreement
supersedes all previous agreements, written or oral, relating to the above subject matter, except for the Nondisclosure and Assignment of Inventions Agreement between me and the Company, which shall remain in full force and effect in accordance with
its respective terms. 
  
 13. Survival.
This Agreement shall be effective as of the date entered below. My obligations under this Agreement shall survive the termination of my employment regardless of the manner of such termination and shall be binding upon my heirs, executors,
administrators and legal representatives. 
  
 14.
Assignment. The Company shall have the right to assign this Agreement to its successors and assigns, and all covenants and agreements hereunder shall inure to the benefit of and be enforceable by said successors or assigns. I will not assign
this Agreement.

 (b) The provisions of this Paragraph shall apply to Proprietary Information obtained by
the Company from any third party under an agreement including restrictions on disclosure known to me. 
  
 3. Inventions. 
  
 (a) If at any time or times during my employment, I shall (either alone or with others) make, conceive, create, discover, invent or reduce
to practice any Development that (i) relates to the business of the Company or any customer of or supplier to the Company or any of the products or services being developed, manufactured or sold by the Company or which may be used in relation
therewith; or (ii) results from tasks assigned to me by the Company; or (iii) results from the use of premises or personal property (whether tangible or intangible) owned, leased or contracted for by the Company, then all such Developments
and the benefits thereof are and shall immediately become the sole and absolute property of the Company and its assigns, as “works made for hire” pursuant to the United States Copyright Act (17 U.S.C. Section 101.) or otherwise. The
term “Development” shall mean any invention, idea, creation, modification, discovery, design, development, improvement, biological or other process, cell line, lab notebook, software program, work of authorship, documentation, formula,
data, technique, know-how, trade secret or intellectual property right whatsoever or any interest therein (whether or not patentable or registrable under copyright, trademark or similar statutes or subject to analogous protection). I shall promptly
disclose to the Company (or any persons designated by it) each, such Development. I hereby assign all rights (including, but not limited to, rights to inventions, patentable subject matter, copyrights and trademarks), title and interest that I may
have or may acquire in the Developments and all benefits and/or rights resulting therefrom to the Company and its assigns without further compensation and shall communicate, without cost or delay, and without disclosing to others the same, all
available information relating thereto (with all necessary plans and models) to the Company. 
  
 (b) I agree that I will promptly disclose to the Company all ideas, inventions, discoveries and improvements (including, but not limited
to, those which are or may be patentable or subject to copyright protection) which I make, originate, conceive or reduce to practice during my employment with the Company and which relate directly or indirectly to the business of the Company or to
work or investigations done for the Company (collectively, “Inventions”). All Inventions shall be the sole and exclusive property of the Company, and I hereby assign to the Company all rights therein, except as may otherwise be
specifically agreed by the Company in writing. I further represent that, to the best of my knowledge and belief, none of the Developments will violate or infringe upon any right, patent, copyright, trademark or right of privacy, or constitute libel
or slander against or violate any other rights of any person, firm or corporation, and that I will use my best efforts to prevent any such violation. 
  
 (c) In order that the Company may protect its rights in the Inventions, I will make adequate written records of all Inventions, which
records shall be the Company’s property; and, both during and after termination of my employment with the Company, I will, without charge to the Company but at its request and expense, sign all papers,

including forms of assignment, and render any other proper assistance necessary or desirable to transfer or record the transfer to the Company of my entire
right, title and interest in and to the Inventions, and for the Company to obtain, maintain and enforce patents, copyrights, trade secrets or other protections thereon or with respect thereto (as the case may be) throughout the world. 
  
 (d) I represent that the Developments identified in the
Appendix, if any, attached hereto comprise all the Developments that I have made or conceived prior to my employment by the Company, which Developments are excluded from this Agreement. I understand that it is only necessary to list the title of
such Developments and the purpose thereof but not details of the Development itself. IF THERE ANY SUCH DEVELOPMENTS TO BE EXCLUDED, THE UNDERSIGNED SHOULD INITIAL HERE, OTHERWISE IT WILL BE DEEMED THAT THERE ARE NO SUCH EXCLUSIONS. __________

  
 (e) The obligations contained in this
Paragraph 3 shall continue beyond the termination of my employment with respect to Inventions (whether patentable or copyrightable or not) conceived or made by me during the period of my employment. 
  
 (f) With respect to any Developments, and work of any
similar nature (from any source), whenever created, which I have not prepared or originated in the performance of my employment, but which I provide to the Company or incorporate in any Company product or system, I hereby grant to the Company a
royalty-free, fully paid-up, non-exclusive, perpetual and irrevocable license throughout the world to use, modify, create derivative works from, disclose, publish, translate, reproduce, deliver, perform, dispose of, and to authorize others so to do,
all such Developments. I will not include in any Developments I deliver to the Company or use on its behalf, without the prior written approval of the Company, any material which is or will be patented, copyrighted or trademarked by me or others
unless I provide the Company with the written permission of the holder of any patent, copyright or trademark owner for the Company to use such material in a manner consistent with then- current Company policy. 
  
 (g) By this Agreement, I irrevocably constitute and appoint
the Company as my agent and attorney-in-fact for the purpose of executing, in my name and on my behalf, such instruments or other documents as may be necessary to transfer, confirm and perfect in the Company the rights I have granted to the Company
in this Paragraph 3 and to do all other lawfully permitted acts to further the prosecution and issuance of patent, copyright or trademark registrations or any other legal protection thereon with the same legal force and effect as if executed by me.

  
 4. Covenant to Report: Documents and Tangible Property.
I will promptly communicate and disclose to the Company all observations made and data obtained by me in the course of my employment by the Company and shall not make, use or permit to be used (at any time) any Company Property otherwise than for
the benefit of the Company. “Company Property” shall include all written materials, records, documents and other tangible property made by me or coming into my possession during my employment concerning the business or affairs of the
Company, including, but not limited to, any Proprietary Information and/or any 

  

 Page 3 of 6 








 
Inventions which are conceived or generated by me. All Company Property shall be the sole and exclusive property of the Company and, upon the termination of
my employment (or at such earlier time as the Company may request me to do so), I will promptly deliver the same, in my possession, custody or control, to the Company or to any party designated by it, without retaining any copies, notes or excerpts
thereof. I agree to render to the Company, or to any party designated by it, such reports of the activities undertaken by me or conducted under my direction during my employment as the Company may request. 
  
 5. Severability and Interpretation. In the event that any provision of
this Agreement is held invalid by a court of competent jurisdiction, the remaining provisions shall nonetheless be enforceable according to their terms. Further, in the event that any provision is held to be overbroad as written, such provision
shall, be deemed amended to narrow its application to the extent necessary to make the provision enforceable according to applicable law and enforced as amended. 
  
 6. Waiver. The Company’s waiver or failure to enforce the terms of this Agreement or any similar agreement in
one instance shall not constitute a waiver of its rights hereunder with respect to other violations of this or any other agreement. In addition, any amendment to or modification of this Agreement or any waiver of any provision hereof must be in
writing and signed by the Company. 
  
 7. Notices. Any
notice which the Company is required or may desire to give to me shall be given to me by personal delivery or registered or certified mail, return receipt requested, addressed to me at the address of record with the Company, or at such other place
as I may from time to time designate in writing. Any notice which I am .required or may desire to give to the Company hereunder shall be given by personal delivery or by registered or certified mail, return, receipt requested, addressed to the
Company at its principal office, or at such other office as the Company may from time to time designate in writing. The date of personal delivery or the dates of mailing any such notice shall be deemed to be the date of delivery thereof. 

 
 8. Acquiescence in Injunction. I understand that if I violate any
provision of this Agreement the Company will be irreparably harmed and will have no adequate remedy at law. The Company shall have the right, in addition to any other rights it may have, to obtain in any court of competent jurisdiction injunctive
relief to restrain any breach or threatened breach of, or otherwise to specifically enforce, this Agreement. 
  
 9. No Conflicting Agreements; Disclosure to Future Employers. I represent and warrant to the Company that I am not subject to any restrictions on
my ability to grant to the Company the rights referred to in this Agreement, and that I have not previously assumed any obligations inconsistent with those of this Agreement. I further represent, warrant and covenant to the Company that I am in
compliance and shall remain in compliance with any and all obligations previously assumed by me to any third party with respect to nondisclosure and assignment of inventions. I have not entered into, and I will not enter into, any agreement either
written or oral in conflict herewith. I will provide, and the Company, in its discretion, may similarly provide, a copy of the covenants contained in this Agreement to any business or enterprise which I may directly or indirectly own, manage,
operate, finance, join, control or in which I may participate in the ownership, management, operation, financing, or control, or with

which I may be connected as an officer, director, employee, partner, principal, agent, representative, consultant or otherwise. 
  
 10. Governing Law. This Agreement and any disputes arising under or in
connection with it shall be governed by the laws of the State of Connecticut, without giving effect to the principles of conflict of laws of such state. I hereby submit for the sole purpose of this Agreement and any dispute arising under or in
connection with it to the jurisdiction of the courts located in the State of Connecticut and any courts of appeal therefrom, and hereby waive any objection (on the grounds of lack of jurisdiction or forum non conveniens or
otherwise) to the exercise of such jurisdiction over me by any such courts. 
  
 11. Survival. This Agreement shall be effective as of the date entered below. My obligations under this Agreement shall survive the termination of my employment regardless of the manner of such termination and
shall be binding upon my heirs, executors, administrators and legal representatives. 
  
 12. Assignment. The Company shall have the right to assign this Agreement to its successors and assigns, and all covenants and agreements hereunder shall inure to the benefit of and, be enforceable by said
successors or assigns. I will not assign this Agreement. 
  
 13.
WAIVER OF JURY TRIAL. ANY ACTION, DEMAND, CLAIM OR COUNTERCLAIM ARISING UNDER OR RELATING TO THIS AGREEMENT WILL BE RESOLVED BY A JUDGE ALONE AND EACH OF THE COMPANY AND I WAIVE ANY RIGHT TO A JURY TRIAL THEREOF.
