Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Footnote (7) to the original Form 4 filed by the Reporting Person on March 5, 2018 incorrectly states that the amount reported in Column 5 includes 6,974 units of common stock granted pursuant to restricted stock unit ("RSU") awards and subject to time-based vesting. As reported in this amendment, the correct number of RSUs is 8,474. Following the transactions reported by the Reporting Person on March 5, 2018 and as of the date of this amendment, the Reporting Person holds 525 shares of common stock outright. The transactions and total amount reported in Column 5 of the original filing are otherwise correctly reported.
(2)	Includes 8,474 units of common stock that were granted pursuant to RSU awards under the athenahealth, Inc. 2007 Stock Option and Incentive Plan, as amended and restated. The RSUs are subject to time-based vesting and will be settled only in stock.
