* 2020 includes $9,505 received in advance of performing services under a license agreement (see Note 15). The remainder of the 2020 and all of the 2021 deferral of revenue resulted from payments received in advance of performance under the biobanking services storage contracts that are recognized as revenue under the contract as performance is completed.

** During the third quarter of 2021, the Company terminated the license agreement with Sanuwave due to an uncured material breach (See Note 15). As a result, the Company recognized the remaining deferred revenue of $6,754 that was to be recognized on a straight-line basis over the non-cancelable term of the license agreement.
