Equity Deferral Program for Employees and Directors, and it was one of several programs offered under the ADTRAN, Inc. Deferred Compensation Plan (the “DCP”). Effective October 1, 2011, the ADTRAN, Inc. Equity Deferral Program for Employees and Directors was spun off from the DCP and split into two separate plans: the ADTRAN, Inc. Equity Deferral Program for Employees and the ADTRAN, Inc. Equity Deferral Program for Directors.

This Plan is intended to be unfunded, maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees of the Employer (as defined below) in compliance with all applicable laws (including Code section 409A), and operated and interpreted in accordance with these intentions.

06507618.2

other distributions become payable with respect to any shares of ADTRAN Holdings, Inc. common stock held in a Participant’s Account or such shares of ADTRAN Holdings, Inc. common stock shall be converted or exchanged into stock or other securities of another entity pursuant to a merger, consolidation, exchange, offer or other transaction, the Participant’s Account shall be credited with such non-cash amounts, which shall continue to be held in such form until the earlier of the date such amounts are distributed to the Participant pursuant to Article VIII or, for Deferral Contributions pursuant to awards vesting on or after November 1, 2011, the date that all or a portion of such amounts are moved to another deemed investment pursuant to an election made by the Participant as described in (b) below.

(or its designee). Any election by a Participant under this paragraph shall become effective as soon as administratively possible, but may be subject to reasonable delays for processing by the Administrator (or its delegate) and Plan recordkeeper.

Notwithstanding any other provision to the contrary, the investments described in this Plan are to be used for measurement purposes only, and the crediting or debiting of amounts to a Participant’s Account shall not be considered or construed in any manner as an actual investment of his or her Account in any investment fund or ADTRAN Holdings, Inc. common stock.

If more than one person is designated as the Beneficiary, their respective interests shall be as indicated on the designation form.

Immediately following the death of the Participant, a copy of the death certificate or other sufficient documentation must be filed with and approved by the Administrator. If upon the death of the Participant there is, in the opinion of the Administrator, no designated Beneficiary for part or all of the Participant’s Account, such amount will be paid to his surviving spouse or, if none, to his estate (such spouse or estate shall be deemed to be the Beneficiary for purposes of the Plan). If a Beneficiary dies after benefits to such Beneficiary have commenced, but before they have been completed, and, in the opinion of the Administrator, no person has been designated to receive such remaining benefits, then such benefits shall be paid to the deceased Beneficiary’s estate.

Page of 13

06507618.2

applicable election. If the Participant does not designate in the manner prescribed by the Administrator the method of distribution, such method of distribution shall be a lump sum.

(d)

A Participant’s entitlement to installments will not be treated as an entitlement to a series of separate payments.

(e)

Notwithstanding anything herein to the contrary, the Administrator may, in its discretion, automatically pay out a Participant’s Account in a lump sum, provided that such payment satisfies the requirements in (1) through (3) below:

(1)

Such payment results in the termination and liquidation of the entirety of the Participant’s interest under the Plan, including all agreements, methods, programs, or other arrangements with respect to which deferrals of compensation are treated as having been deferred under a single nonqualified deferred compensation plan under Treasury Regulations section 1.409A-1(c)(2);

(2)

Such payment is not greater than the applicable dollar amount under Code section 402(g)(1)(B); and

(3)

Such exercise of Administrator discretion is evidenced in writing no later than the date of such payment.

(1)

In the event the Administrator reasonably anticipates that, if the payment were made as scheduled, the Employer’s deduction with respect to such payment would not be permitted due to the application of Code section 162(m), provided the delay complies with the conditions in Treasury Regulations section 1.409A-2(b)(7)(i);

(2)

In the event the Administrator reasonably anticipates that the making of such payment will violate Federal securities laws or other applicable law, provided the delay complies with the conditions in Treasury Regulations section 1.409A-2(b)(7)(ii);

(3)

Upon such other events and conditions as the Commissioner of the Internal Revenue Service may prescribe in generally applicable guidance published in the Internal Revenue Bulletin; or

(4)

Upon a change in control event, provided the delay complies with conditions in Treasury Regulations section 1.409A-3(i)(5)(iv).

(g)

Notwithstanding anything herein to the contrary, the Administrator may provide an election to change the time or form of a payment hereunder to satisfy the requirements of the Uniformed Services Employment and Reemployment Rights Act of 1994, as amended, 38 USC sections 4301 through 4344.

Participants are solely responsible and liable for the satisfaction of all taxes and penalties that may arise in connection with this Plan (including any taxes arising under Code section 409A). Neither the Employer nor its affiliates nor any of their directors, officers or employees shall have any obligation to indemnify or otherwise hold any Participant harmless from any such taxes.

ARTICLE IX AMENDMENT AND TERMINATION

9.1

Amendment by Employer. ADTRAN Holdings, Inc. reserves the authority to amend the Plan in its discretion.

10.1

Limitation of Rights.

Pursuant to a

Page of 13

06507618.2

domestic relations order, payments may be accelerated to a time sooner, and pursuant to a schedule more rapid, than the time and schedule applicable in the absence of the domestic relations order, provided that such payment pursuant to such order is not made to the Participant and provided further that this provision shall not be construed to provide the Participant discretion regarding whether such payment time or schedule will be accelerated.

10.3

Facility of Payment. In the event the Administrator determines, on the basis of medical reports or other evidence satisfactory to the Administrator, that the recipient of any benefit payments under the Plan is incapable of handling his affairs by reason of minority, illness, infirmity or other incapacity, the Administrator may disburse such payments, or direct the Trustee to disburse such payments, as applicable, to a person or institution designated by a court which has jurisdiction over such recipient or a person or institution otherwise having the legal authority under state law for the care and control of such recipient.

Although the principal of each Trust and any earnings thereon shall be held separate and apart from other funds of Employer and shall be used exclusively for the uses and purposes of Participants and there Beneficiaries as set forth therein, neither the Participants nor their Beneficiaries shall have any preferred claim on, or any beneficial ownership in, any assets of the Trust prior to the time such assets are paid to the Participants or their Beneficiaries as benefits and all rights created under this Plan shall be unsecured contractual rights of Participants and their Beneficiaries against the Employer.

The Administrator will notify such person of its decision in writing. Such notification will be written in a manner calculated to be understood by such person and will contain specific reasons for the decision as well as specific references to pertinent Plan provisions. The decision on review will be made within 60 days after the request for review is received by the Administrator (or within 120 days, if special circumstances require an extension of time for processing the request, such as an election by the Administrator to hold a hearing, and if written notice of such extension and circumstances is given to such person within the initial 60-day period). The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render the determination on review.

The Plan Administrator shall provide the claimant with written notification of the Plan’s benefit determination on review. In the case of an adverse benefit determination, the notification shall set forth, in a manner calculated to be understood by the claimant — the specific reason or reasons for the adverse determinations, reference to the specific Plan provisions on which the benefit determination is based, a statement that the claimant is entitled to receive, upon the claimant’s request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claim for benefits.

11.3

Indemnification by the Employer: Liability Insurance. The Employer shall pay or reimburse any of the Employer’s officers, directors, administrators, subcommittee members, delegates, or employees who are fiduciaries with respect to the Plan for all expenses incurred by such persons with respect to, and shall indemnify and hold them harmless from, all claims, liability and costs (including reasonable attorneys’ fees) arising out of the good faith performance of their duties under this Plan. The Employer may obtain and provide for any such person, at the Employer’s expense, liability insurance against liabilities imposed on such person by law.
