Item 1.01.    Entry into a Material Definitive Agreement.
On April 12, 2019, Cyanotech Corporation (the "Company") obtained an unsecured subordinated loan from Skywords Family Foundation, Inc. ("Skywords") in the principal amount of $1,500,000 pursuant to a Promissory Note (the "Note") executed by the Company in favor of Skywords.  Skywords is controlled by Michael Davis, the Company's Chairman of the Board of Directors and largest stockholder.  The Note bears interest at a rate of 1% plus the prime rate (as published by the Wall Street Journal), which will be recalculated and payable on a quarterly basis.  The principal amount and any accrued and unpaid interest will be due and payable on April 12, 2021, unless accelerated in an event of default.  The Company may prepay the Note at any time without penalty. The proceeds of the Note will be used to pay down accounts payable and for general operating capital purposes.
The financing was undertaken to address a decrease in cash and cash equivalents due to decreased sales, resulting primarily from changes in purchasing and inventory practices among some of our major customers.  The Company continues to work with its customers to help determine purchasing requirements and inventory levels, and is considering alternatives to address resulting periodic changes in cash requirements.
The foregoing description of the Note does not purport to be complete and is qualified in its entirety by reference to the full text of the Note, a copy of which is filed by the Company as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 1.01.
Item 2.03.    Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.
The disclosure in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.
