The KeyBank Credit Facility includes a commitment of $350.0 million from KeyBank and other banks and allows the Company, through TCF, to borrow up to $400.0 million. Borrowings under the KeyBank Credit Agreement bear interest at a rate equal to Adjusted Term SOFR plus 2.85%, subject to the number of eligible loans in the collateral pool. The KeyBank Credit Facility provides for a variable advance rate of up to 60% on eligible term loans and up to 64% on eligible equipment finance loans.

The KeyBank Credit Facility includes a three-year revolving period and a two-year amortization period and matures on October 27, 2026, unless extended. Such credit facility is collateralized by all investment assets held by TCF. The KeyBank Credit Agreement contains representations and warranties and affirmative and negative covenants customary for secured financings of this type, including certain financial covenants such as a consolidated tangible net worth requirement and a required asset coverage ratio.

The KeyBank Credit Agreement also contains customary events of default (subject to certain grace periods, as applicable), including but not limited to the nonpayment of principal, interest or fees; breach of covenants; inaccuracy of representations or warranties in any material respect; voluntary or involuntary bankruptcy proceedings; and change of control of the borrower without the prior written consent of KeyBank.

The 2025 Notes have the same CUSIP number and are fungible and rank equally.

On December 11, 2020, the Company completed a private offering (the “Private Convertible Note Offering”) of $50.0 million in aggregate principal amount of its unsecured Convertible Notes in reliance upon the available exemptions from the registration requirements of the Securities Act. KBW acted as the initial purchaser and placement agent in connection with the Private Convertible Note Offering pursuant to a purchase/placement agreement dated December 4, 2020, by and between the Company and KBW.

The Convertible Notes were issued pursuant to the Base Indenture and a Second Supplemental Indenture, dated as of December 11, 2020 (the “Second Supplemental Indenture” and together with the Base Indenture, the

“Convertible Notes Indenture”), between the Company and the Trustee. Concurrent with the closing of the Convertible Note Offering, on December 11, 2020, the Company entered into a registration rights agreement for the benefit of the holders of the Convertible Notes and the shares of common stock issuable upon conversion thereof. Aggregate offering costs in connection with the Convertible Note Offering, including the initial purchaser and placement agent discount and commissions, were approximately $1.9 million, which were capitalized and deferred.

The Convertible Notes bear interest at a fixed rate of 6.00% per year, subject to additional interest upon certain events, payable semiannually in arrears on May 1 and November 1 of each year, beginning on May 1, 2021. If an investment grade rating is not maintained with respect to the Convertible Notes, additional interest of 0.75% per annum will accrue on the Convertible Notes until such time as the Convertible Notes have received an investment grade rating of “BBB-” (or its equivalent) or better. The rating remained at investment grade as of March 31, 2024. The Convertible Notes mature on December 11, 2025 (the “Convertible Notes Maturity Date”), unless earlier converted or repurchased in accordance with their terms.

Holders may convert their Convertible Notes, at their option, at any time on or prior to the close of business on the business day immediately preceding the Convertible Notes Maturity Date. The conversion rate was initially 66.6667 shares of the Company’s common stock, per $1,000 principal amount of the Convertible Notes (equivalent to an initial conversion price of approximately $15.00 per share of common stock). Effective immediately after the close of business on March 28, 2024, the conversion rate changed to 78.0543 shares of the Company’s common stock, per $1,000 principal amount of the Convertible Notes (equivalent to a conversion price of approximately $12.81 per share of common stock) as a result of a certain cash dividend of the Company. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events, further described in the Convertible Note Indenture, that occur prior to the Convertible Notes Maturity Date, the Company will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event in certain circumstances. Upon conversion of the Convertible Notes, the Company will pay or deliver, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, at the Company’s election, per $1,000 principal amount of the Convertible Notes, equal to the then existing conversion rate.

At the Company’s option, it may cause holders to convert all or a portion of the then outstanding principal amount of the Convertible Notes plus accrued but unpaid interest, at any time on or prior to the close of business on the business day immediately preceding the Convertible Notes Maturity Date, if the closing sale price of the Company’s common stock for any 30 consecutive trading days exceeds 120% of the conversion price, as may be adjusted. Upon such conversion, the Company will pay or deliver, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, at the Company’s election, per $1,000 principal amount of the Convertible Notes, equal to the then existing conversion rate, and a forced conversion make-whole payment (as defined in the Second Supplemental Indenture), if any, in cash. Otherwise, the Company may not redeem the Convertible Notes at its option prior to maturity.

In addition, if the Company undergoes a fundamental change (as defined in the Second Supplemental Indenture), holders may require the Company to repurchase for cash all or part of such holders’ Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Convertible Notes are direct unsecured obligations of the Company and rank pari passu, or equal in right of payment, with all of the Company’s existing and future unsecured indebtedness or other obligations that are not so subordinated, and senior in right of payment to all of the Company’s future indebtedness or other obligations that are expressly subordinated, or junior, in right of payment to the Convertible Notes.

The Convertible Notes are accounted for in accordance with ASC 470-20, Debt Instruments with Conversion and Other Options. In accounting for the Convertible Notes, the Company estimated at the time of issuance that the values of the debt and the embedded conversion feature of the Convertible Notes were approximately 99.1% and 0.9%, respectively.
