Loan description       We are in current discussions with Pinnacle and negotiating with them in good faith on these terms, and expect to come to a mutually agreeable outcome, which, at this time, we believe will provide that Pinnacle will accept certain amounts we expect to receive in purchase orders over the next few months ($325 by December 15, 2025), provided that if such purchase orders are not fulfilled, $325 will be due in December, regardless, and in each case the balance outstanding ($155) will be due by January 15, 2026. While the Company believes it has a good working relationship with Pinnacle, Pinnacle could seek other remedies against the Company pursuant to the Loan Agreement or terminate the Loan Agreement. If the Company is unable to comply with the Loan Agreement, or amendments if applicable, the Company may lose its financing with Pinnacle.
