This Employment Agreement (this “Agreement”) is made and entered into as of this 12th day of December, 2014, by and between Vertex Pharmaceuticals Incorporated, a Massachusetts corporation (together with its successors and assigns, the “Company”), and David Altshuler, M.D., Ph.D. (the “Executive”).  
W IT N E S S E T H 
WHEREAS, the Company is employing the Executive as the Company’s Executive Vice President, Global Research, & Chief Scientific Officer;
WHEREAS, the Executive has been designated as a member of the Executive and Management Committees of the Company; and
WHEREAS, the Executive has agreed as a condition precedent to the foregoing to resign from the Board of Directors, and the Company has accepted said resignation;
NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and for other good and valuable consideration, the receipt of which mutually is acknowledged, the Company and the Executive (each individually a “Party”, and together the “Parties”) agree as follows: 
1. DEFINITIONS. 
“Base Salary” shall mean the Executive’s base salary in accordance with Section 4 below. 
“Board” shall mean the Board of Directors of the Company. 
“Cause” shall mean (i) the Executive is convicted of a crime involving moral turpitude, (ii) the Executive commits a material breach of any provision of this Agreement not involving the performance or nonperformance of duties, or (iii) the Executive, in carrying out the Executive’s duties, acts or fails to act in a manner that is determined, in the sole discretion of the Board, after written notice of any such act or failure to act and a reasonable opportunity to cure the deficiency has been provided to the Executive, to be (A) willful gross neglect or (B) willful gross misconduct resulting, in either case, in material harm to the Company unless such act, or failure to act, was believed by the Executive, in good faith, to be in the best interests of the Company.  
“Change of Control” shall have the meaning set forth in the Change of Control Agreement. 


“Change of Control Agreement” shall mean the Change of Control letter agreement between the Company and the Executive of even date herewith.
“Code” shall mean the Internal Revenue Code of 1986, as amended.   
“Common Stock” shall mean the common stock of the Company. 
“Disability” or “Disabled” shall mean a disability as determined under the Company’s long-term disability plan or program in effect at the time the disability first occurs, or if no such 

166933_4    




Exhibit 10.34


plan or program exists at the time of disability, then a “disability” as defined under Section 22(e)(3) of the Code.
“Effective Date” shall mean January 12, 2015. 
“Good Reason” shall mean that, without the Executive’s consent, one or more of the following events occurs: 
		
	(i)
	 the Executive’s duties are materially diminished to an extent that results in either (A) the Executive no longer being an “officer,” as such term is defined in Rule 16a-1(f) promulgated under the Securities Exchange Act of 1934; or (B) the Executive ceases to be a member of the executive management team of the Company; or


		
	(ii)
	the Executive’s Base Salary is decreased unless such reduction is part of an across-the-board proportionate reduction in the salaries of the Company’s senior management team; or


		
	(iii)
	the office to which the Executive is assigned is relocated to a place 35 or more miles away and such relocation is not at the Executive’s request or with the Executive’s prior agreement (and other than, for Executives assigned to the Company’s principal executive offices, in connection with a change in location of the Company’s principal executive offices);


provided that Good Reason shall not exist unless and until within 30 days after the event giving rise to Good Reason under either (i) or (ii) above has occurred, the Executive delivers a written termination notice to the Company stating that an event giving rise to Good Reason has occurred and identifying with reasonable detail the event that the Executive asserts constitutes Good Reason under either (i) or (ii) above and the Company fails or refuses to cure or eliminate the event giving rise to Good Reason on or within 30 days after receiving such notice.  To avoid doubt, the termination of the Executive’s employment would become effective at the close of business on the thirtieth day after the Company receives the Executive’s termination notice, unless the Company cures or eliminates the event giving rise to Good Reason prior to such time.
“Severance Payment” shall mean an amount equal to the sum of the Base Salary in effect on the date of termination of Executive’s employment, plus the amount of the Target Bonus for the Executive for the year in which the Executive’s employment is terminated; provided, however, that if the Executive terminates the Executive’s employment for Good Reason based on a reduction in Base Salary, then the Base Salary to be used in calculating the Severance Payment shall be the Base Salary in effect immediately prior to such reduction in Base Salary. 
“Target Bonus” shall mean the target cash bonus for which the Executive is eligible on an annual basis, at a level consistent with the Executive’s title and responsibilities, under the Company’s bonus program then in effect and applicable to the Company’s senior executives generally.

Exhibit 10.34


the Company, its subsidiaries, and their officers, directors, agents and representatives, which is executed by Executive and becomes enforceable and non-revocable within 60 days of the date of termination): 
		
	(i)
	Base Salary earned by Executive but not paid through the date of termination of Executive’s employment under this Section 9(c); 


		
	(ii)
	all incentive compensation awards earned by Executive but not paid prior to the date of termination of Executive’s employment under this Section 9(c); 


		
	(iii)
	a cash payment to the Executive in an amount equal to the Severance Payment, payable within ten days after the execution of a general release and expiration, without revocation, of any applicable revocation periods under the general release provided that if the 60-day period during which the release is required to become effective and irrevocable begins in one calendar year and ends in another calendar year, the Severance Payment shall not be made before the first day of the second calendar year; 


		
	(iv)
	any amounts earned, accrued or owing to the Executive but not yet paid under Sections 5, 6 or 7 above; 


		
	(v)
	if COBRA coverage is elected by the Executive, the Company shall pay the cost of insurance continuation premiums on the Executive’s behalf (whether or not covered by COBRA) to continue standard medical, dental and life insurance coverage for the Executive (or the cash equivalent of same in the event the Executive is ineligible for continued coverage) until the earlier of: 


		
	(A)
	the date 12 months after the date the Executive’s employment is terminated; or 


		
	(B)
	the date, or dates, on which the Executive receives equivalent coverage and benefits under the plans, programs and/or arrangements of a subsequent employer (such coverage and benefits to be determined on a coverage-by-coverage or benefit-by-benefit basis). 


If Executive is a “specified employee” under Section 409A(a)(2)(B)(i) of the Code, any payment of “nonqualified deferred compensation” (as defined under Section 409A of the Code and related guidance) attributable to a “separation from service” (as defined under Section 409A of the Code and related guidance) shall not commence until the first full business day that is more than six months after the applicable separation from service (“Deferred Payment Date”).  Any payments that would otherwise have been made between the separation from service and the Deferred Payment Date, but for this paragraph, shall be made in a lump sum on the Deferred Payment Date.  Payments that, in any case, are scheduled to be made after the Deferred Payment Date shall continue according to the applicable payment schedule.  To the extent that the termination of the Executive’s employment does not constitute a separation of service under Section 409A(a)(2)(A)(i) of the Code (as the result of further services that reasonably are anticipated to be provided by the Executive to the Company at the time the Executive’s employment is terminated), the payment of any nonqualified deferred compensation will be further delayed until the date that is the first full business day that is more than six months after 

166933_4        5




Exhibit 10.34


the date of a subsequent event constituting a separation of service under Section 409A(a)(2)(A)(i) of the Code.

Any waiver must be in writing and signed by the Executive or an authorized officer of the Company, as the case may be. 
15. SEVERABILITY. 
If any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, in whole or in part, the remaining provisions of this Agreement shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by law.
