Item 1.01 Entry into a Material Definitive Agreeement.

On August 20, 2015, Principal Solar, Inc. (the “Company”) issued a Convertible Corporate Promissory Note (the “Note”) to Arowana International Limited (the “Lender”) in the original principal amount of $1,600,000. The Note matures on December 31, 2016, and bears simple interest at the rate of 6% per annum.

The Company used the proceeds from the Note to make investments in Innovative Solar 31, LLC; Innovative Solar 33, LLC; and Innovative Solar 47, LLC (the “Solar Projects”). The Solar Projects serve as collateral for the Company’s obligations under the Note.

The principal amount of the Note may be converted, at the Lender’s option, into limited liability company membership interests in Principal Sunrise V, LLC, at a conversion price determined with reference to the unlevered after tax project IRR that reflects the Lender’s investment valuation of Principal Sunrise V and other projects funds by the proceeds of the Note. The Company may pre-pay the Note at any time without pre-payment premium or penalty.

Subject to satisfactory completion of its due diligence, Lender commits to contribute equity capital in amounts sufficient to fund project development to completion of Principal Sunrise V and other projects funded by the proceeds of the Note. If, following Lender's completion of its due diligence on Principal Sunrise V, the Company and the Lender agree the project does not meet its investment return requirements, the parties agree to work in good faith to identify a substitute solar project as security under the Note.

The parties are obligated to enter into a strategic relationship providing Lender an opportunity to invest in the project equity in each of the Solar Projects, or equivalent substitute projects. Failure of the Company and Lender to reach such agreement on or before September 30, 2015, which such date may be extended by mutual agreement, shall be an Event of Default giving rise to Company's forfeiture of the Collateral to Lender, and the satisfaction and cancellation of the Note.
