The reporting person undertakes to provide to Accelerate Diagnostics, Inc. (the "Issuer"), any shareholder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the range set forth in this footnote (1) to this Form 4. ( 2 )Due to a clerical error, the reported shares owned indirectly by the reporting person through the John Patience Living Trust dated 7/23/1993 (the "Trust") has been adjusted to correct an understatement of 104,270 shares.

( 3 )These shares were previously reported as owned indirectly by the reporting person through the John Patience Defined Benefit Pension Plan but are now owned indirectly by the reporting person in the reporting person's individual retirement account (IRA). ( 4 )Due to a clerical error, the reported shares owned indirectly by the reporting person through Patience Enterprises LP (the "Partnership") has been adjusted to correct an understatement of 29,800 shares. The 29,800 shares were acquired by the Partnership on May 2, 2014, which were previously reported in the reporting person's Form 4 filed May 2, 2014 and inadvertently omitted in subsequent filings.
