Further, if the Company or any of its subsidiaries incurs unsecured indebtedness under the uncapped general indebtedness basket or permitted convertible indebtedness basket of the Credit Agreement in excess of $50 million in connection with a transaction that is a Springing Covenant Event or during a Springing Covenant Period, then the maximum consolidated senior secured net leverage ratio shall be, or shall automatically step down to, 3.50:1.00 at the time of such incurrence. The First Amendment further added additional financial flexibility by amending the $30 million external debt capped basket to be an unlimited amount and permitting, subject to certain requirements, the incurrence of convertible indebtedness by the Company in an aggregate principal amount of up to $172.5 million. Any such convertible indebtedness must be incurred in pro forma compliance with the financial covenants in the Credit Agreement, unsecured and otherwise rank junior to borrowings under the Credit Agreement, and have a stated maturity date of at least 91 days after the latest scheduled maturity date of loans and commitments under the Credit Agreement. Net cash proceeds from any incurrence of convertible indebtedness must be used to repurchase minority shares of Adtran Networks or repay revolver borrowings under the Credit Agreement. Lastly, the First Amendment added market environmental, social and governance provisions and extended the required delivery date of the financial statements of the Company and its subsidiaries for the fiscal quarter ended June 30, 2023 to August 18, 2023.

Proceeds of the DDTL may only be used to repurchase minority shares of Adtran Networks. The DDTL remains available for borrowing from the occurrence of a Springing Covenant Event through the period that is three consecutive fiscal quarters thereafter;

•

a revised applicable margin, which varies based on consolidated total net leverage ratio and ranges from, (a) in the case of revolving loans, (i) 1.65%, with respect to term SOFR loans, to 2.65%, (ii) 1.75%, with respect to EURIBOR loans, to 2.75% and (iii) 0.65%, with respect to base rate loans (including swingline loans) to 1.65%, and (b) in the case of term loans, ranging from (i) 1.90%, with respect to term SOFR loans, to 2.90% and (ii) 0.90%, with respect to Base Rate Loans, to 1.90% (each as defined in the First Amendment to the Credit Agreement);

•

a revised commitment fee, which varies based on consolidated total net leverage ratio and ranges from 0.20% to 0.25% per annum on the average daily unused portion of the revolving credit commitment of the revolving credit lenders (other than the defaulting lenders, if any) (each as defined in the credit agreement); and

•

revised financial covenants, including (i) the addition of an automatic step up in the consolidated total net leverage ratio to 5.00:1.00 from 3.25:1.00 upon the occurrence of a Springing Covenant Event and continuing for the fiscal quarter in which the Springing Covenant Event occurs and the next three consecutive fiscal quarters thereafter (such period, a “Springing Covenant Period”) and (ii) the addition of a consolidated senior secured net leverage ratio covenant to be tested quarterly during a Springing Covenant Period and sized at 4.00:1.00 during the first quarter ending after a Springing Covenant Event, 3.75:1.00 during the second quarter ending after a Springing Covenant Event and 3.50:1.00 during the third and fourth quarters ending after a Springing Covenant Event. Further, if the Company or any of its subsidiaries incurs unsecured indebtedness under the uncapped general indebtedness basket or permitted convertible indebtedness basket of the Credit Agreement in excess of $50 million in connection with a transaction that is a Springing Covenant Event or during a Springing Covenant Period, then the maximum consolidated senior secured net leverage ratio shall be, or shall automatically step down to, 3.50:1.00 at the time of such incurrence.

The First Amendment further added additional financial flexibility by amending the $30 million external debt capped basket to be an unlimited amount and permitting, subject to certain requirements, the incurrence of convertible indebtedness by the Company in an aggregate principal amount of up to $172.5 million. Any such convertible indebtedness must be incurred in pro forma compliance with the financial covenants in the Credit Agreement, unsecured and otherwise rank junior to borrowings under the Credit Agreement, and have a stated maturity date of at least 91 days after the latest scheduled maturity date of loans and commitments under the Credit Agreement. Net cash proceeds from any incurrence of convertible indebtedness must be used to repurchase minority shares of Adtran Networks or repay revolver borrowings under the Credit Agreement.

Lastly, the First Amendment added market environmental, social and governance provisions and extended the required delivery date of the financial statements of the Company and its subsidiaries for the fiscal quarter ended June 30, 2023 to August 18, 2023.
