17.17Standstill.

17.17.1Except as permitted by the last sentence of this Section 17.17, during the Term of this Agreement and for a period of twelve (12) months thereafter, without the prior written consent of the Board of Directors of Tandem, DexCom and its officers, directors and Affiliates, will not directly or indirectly in any manner: (i) acquire, announce an intention to acquire, or agree to acquire, directly or indirectly, alone or in concert with others, by purchase, gift or otherwise, any direct or indirect beneficial ownership (within the meaning of Rule 13d-3

under the Securities Exchange Act of 1934 (the “Exchange Act”)) or interest in any securities or direct or indirect rights, warrants or options to acquire, or securities convertible into or exchangeable for, any securities of Tandem (ii) make, or in any way participate in, directly or indirectly, alone or in concert with others, any “solicitation” of “proxies” to vote (as such terms are used in the proxy rules of the SEC promulgated pursuant to Section 14 of the Exchange Act) any securities of Tandem with respect to any business combination, restructuring, recapitalization or similar transaction; (iii) form, join or in any way participate in a “group” within the meaning of Section 13(d)(3) of the Exchange Act with respect to any voting securities of Tandem; (iv) acquire, announce an intention to acquire, or agree to acquire, directly or indirectly, alone or in concert with others, by purchase, exchange or otherwise, (a) any of the assets, tangible or intangible, of Tandem or (b) direct or indirect rights, warrants or options to acquire any assets of Tandem, other than in the ordinary course of business; (v) enter into any arrangement or understanding with, or otherwise assist or encourage, others to do any of the actions restricted or prohibited under clauses (i), (ii), (iii) or (iv) of this Section 17.17; (vi) otherwise act in concert with others, to seek to offer to Tandem or any of its stockholders any business combination, restructuring, recapitalization or similar transaction to or with Tandem, or (vii) take any action to control the management, Board of Directors or policies of Tandem. Notwithstanding the above, cumulative acquisitions by DexCom, including any Affiliate of DexCom, of less than one percent (1%) of Tandem's outstanding common shares shall not be deemed a breach of this provision.

17.17.2The standstill provisions of Section 17.17.1 shall not apply in the event that, without any violation of the standstill provision, (i) a Third Party unrelated to DexCom shall have entered into a definitive agreement with Tandem to acquire more than 50% of the outstanding common stock of Tandem, or (ii) a Third Party unrelated to DexCom commences a tender offer for more than 50% of the outstanding common stock of Tandem that the board of directors of Tandem recommends. The standstill provisions of Section 17.17.1 shall automatically become applicable again if the Third Party announces its intent not to proceed with the acquisition or commenced tender offer.

17.17.3DexCom recognizes that, if it fails to perform or breaches any of its obligations under this Section 17.17, any remedy at law may prove to be inadequate relief to Tandem. DexCom therefore agrees that Tandem is entitled to seek temporary and permanent injunctive relief or specific performance in any such case.
