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) This statement is being filed by The Goldman Sachs Group, Inc. ("GS Group") and Goldman Sachs & Co. LLC ("Goldman Sachs" and together with GS Group, the "Reporting Persons"). Goldman Sachs is a subsidiary of GS Group. The Reporting Persons disclaim beneficial ownership of the securities reported herein except to the extent of their pecuniary interest therein, if any.
(2) The 18,000 shares of common stock, par value $0.001 per share (the "Common Stock"), were granted pursuant to T2 Biosystems, Inc.'s (the "Company") Amended and Restated 2014 Incentive Award Plan under the Company's Non-Employee Director Compensation Plan (the "Plan"), consisting of 18,000 restricted stock units granted to Adrian M. Jones, a managing director of Goldman Sachs, in his capacity as a director of the Company. The grant of 18,000 restricted stock units shall become fully vested on the first anniversary of the date of grant, which was June 2, 2017, subject to Mr. Jones continuing in service on the Company's board of directors through such vesting date. Each restricted stock unit represents a contingent right to receive one share of the Company's Common Stock. Mr. Jones has an understanding with GS Group pursuant to which he holds such securities for the benefit of GS Group.
(3) GS Group may be deemed to beneficially own 18,000 shares of Common Stock by reason of 18,000 restricted stock units that were granted to Mr. Jones pursuant to the Plan. The Reporting Persons may be deemed to beneficially own indirectly, in the aggregate, 4,157,240 shares of Common Stock of the Company by reason of the direct beneficial ownership of Common Stock by certain investment entities (the "GS Funds") because GS Group, or affiliates of GS Group and Goldman Sachs, are the general partner, managing general partner, managing partner, managing member or member of each of the GS Funds. Goldman Sachs is the investment manager of certain of the GS Funds.
(4) The options to purchase 66,176 shares of Common Stock of the Company were granted to Mr. Jones in his capacity as a director of the Company pursuant to the Plan. The options vest and become exercisable in substantially equal installments on each of the first three anniversaries of the date of grant, which was March 9, 2016, subject to Mr. Jones continuing in service on the Company's board of directors through each such vesting date. Mr. Jones has an understanding with GS Group pursuant to which he holds such options for the benefit of GS Group.
