| 9. | Rights Agreement
In consideration of Molteni’s entry into the Restated Loan Agreement and the Purchase Agreement, on March 21, 2018, we entered into an agreement (as amended in May 2018, the “Rights Agreement”) with Molteni pursuant to which we agreed to (i) issue Molteni seven-year warrants to purchase 540,000 shares of our common stock at an exercise price of $1.20 per share (the “Molteni Warrants”), (ii) provide Molteni customary demand and piggy-back registration rights with respect to the shares of common stock issuable upon conversion of its loan and exercise of the Molteni Warrants, (iii) appoint one member of our board of directors under certain circumstances and (iv) provide board observer rights to Molteni if it has not designated a board nominee as well as certain information rights. The board designation, observer and information rights will terminate at such time as Molteni ceases to beneficially own at least one percent of our outstanding capital stock (inclusive of the shares issuable upon conversion of debt under the Restated Loan Agreement and exercise of the Molteni Warrants). The Molteni Warrants have been classified as equity and their fair value at the time of issuance was determined using a Black Scholes valuation model. The amount was allocated equally between the Restated Loan Agreement and the Purchase Agreement and was recorded in the Condensed Balance Sheet as a discount to the debt obligation and a contract asset, respectively. The key assumptions used to value the Molteni Warrants were as follows:
