 Exhibit 10.21.1 
 ITC^DELTACOM, INC. 
 EXECUTIVE STOCK INCENTIVE PLAN 
 This ITC^DELTACOM, INC. EXECUTIVE STOCK INCENTIVE PLAN authorizes our Board, or a Committee appointed by the Board, to grant Stock Units. References to
the Board will include the Committee, if one is appointed and acting within the authority delegated to it. The Plan supplies a number of standard terms and conditions for Stock Units that will apply unless the Board provides otherwise in a
particular case. We have provided definitions for capitalized terms in Section 17 below. 
 1. PURPOSE 
 We adopted the Plan on May 10, 2005 so that we may grant our equity securities as an inducement material to certain senior executives entering into
employment with the Company within the meaning of Nasdaq Marketplace Rule 4350(i)(1)(A)(iv) who have been hired to provide services to us or our Affiliates. We believe that equity ownership will create strong incentives for these individuals to
produce good business results for us by giving them an opportunity to acquire a proprietary interest in ITC^DeltaCom, Inc. We believe that equity ownership will encourage these individuals to do their best to help us to achieve our corporate
objectives and that these individuals also will be more likely to stay with us instead of pursuing other employment or business opportunities. 
 We amended and restated the Plan effective on December 20, 2005. 
 We refer to Stock Units as “Incentive Awards.”

 2. ADMINISTRATION 
 (a) Board of Directors. The Board will administer the Plan. The Board will have the full power and authority to take all actions and to make all determinations required or permitted under the Plan consistent with the terms of each
Agreement. If any Incentive Award or Agreement needs to be interpreted or amended or if any other action by us is necessary or desirable to implement the Plan or any Incentive Award, the Board will have the authority to take those actions, in its
discretion. The Board will take action and make determinations in accordance with our Certificate of Incorporation and Bylaws by written consent in lieu of a meeting or by the affirmative vote of a majority of the members of the Board who are
present at a meeting at which any issue relating to the Plan is properly raised for consideration. 
 (b) Committee. The Board may
appoint a Committee and delegate all or a portion of the Board’s authority for the administration of the Plan to the Committee. The Committee will take action and make determinations in accordance with our Certificate of Incorporation and
Bylaws by written consent in lieu of a meeting or by the affirmative vote of a majority of the members of the Committee who are present at a meeting at which any issue relating to the Plan is properly raised for consideration. 







 (c) No Liability. No member of the Board or the Committee will be liable for any action or
determination made in good faith with respect to the Plan or any Incentive Award or Agreement. 
 (d) Scope and Effect of
Delegation to the Committee. If our Board delegates to the Committee the power and authority to take an action or make a determination, the Committee will have the same power and authority, to the extent delegated, that the Board
would have had. When the Board delegates power and authority to the Committee, the Board may retain the power and authority to take final actions and make final determinations itself. 
 3. STOCK 
 We may issue shares of our
Stock under the Plan, either from treasury shares or from our authorized but unissued shares of Stock. We will not issue more than (a) 2,000,000 shares of Common Stock, (b) 25,000 shares of Series A Preferred Stock and (c) 70,000
shares of Series B Preferred Stock under the Plan. We will adjust the foregoing numbers of shares as appropriate to reflect changes in our capitalization, as provided in Section 13 below. 
 4. ELIGIBILITY 
 We may grant
Incentive Awards to any Eligible Individual. 
 5. EFFECTIVE DATE AND TERM OF THE PLAN 
 (a) Effective Date. The Plan became effective on the Effective Date, which is the date on which the Board adopted the Plan. 
 (b) Term. Unless earlier terminated by the Board, the Plan will terminate eight years after the Effective Date. 
 6. STOCK UNITS 
 (a) Stock
Units. The Board may grant Stock Units to an Eligible Individual. Stock Units granted to an Eligible Individual will have the terms set forth in such Eligible Individual’s Agreement and, to the extent not set forth in such Agreement, in the
Plan. 
 (b) Delivery of Stock. Upon satisfying the specified Conditions applicable to such Stock Units, and unless otherwise set
forth in the Holder’s Agreement (including any deferral election form executed by such Holder thereunder), the Company will deliver to the Holder or the Holder’s beneficiary or estate, as the case may be, a certificate or certificates
evidencing the shares of Stock represented by the Stock Units. Notwithstanding the foregoing: 
 (i) if a Holder is a
“key employee” within the meaning of Code section 409A and shares of Stock would otherwise be delivered to such Holder on account of the termination of such Holder’s employment with the Company and its Affiliates, then such shares
will not be delivered to such Holder until six months (or such lesser period as may be permitted by Code section 409A) after such termination of employment to the extent necessary to avoid the imposition of the penalty under Code section 409A; and

  

 - 2 - 








 (ii) if the shares relating to the vested Stock Units would otherwise be delivered
during a period in which a Holder is (A) subject to a lock-up agreement restricting such Holder’s ability to sell shares of Stock in the open market, (B) restricted from selling shares of Stock in the open market because such Holder
is not then eligible to sell shares of Stock under the Company’s insider trading or similar plan or policy as then in effect (whether because a trading “window” is not open or such Holder is otherwise restricted from trading) or
(C) restricted from selling shares of Stock pursuant to an effective registration statement because of an applicable blackout thereunder, delivery of the shares of Stock related to the vested Stock Units will be delayed until no earlier than
the first date on which such Holder is no longer prohibited from selling shares of Stock due to a lock-up agreement, insider trading plan or policy restriction or applicable blackout, but in no event later than the end of the calendar year in which
the shares related to such vested Stock Units would otherwise have been delivered. 
 (c) Vesting of Incentive Awards. Incentive
Awards granted to an Eligible Individual under the Plan will vest in accordance with the terms set forth in such Eligible Individual’s Agreement and, to the extent not set forth in such Agreement, in the Plan. 
 (d) Waiver of Restrictions and Acceleration. By written notice to a Holder, the Board may waive restrictions and may accelerate the date on which
an Incentive Award may become vested. 
 7. RIGHTS OF HOLDERS OF STOCK UNITS 
 (a) No Rights as Stockholders. Holders of Stock Units will have no rights as stockholders of the Company, including without limitation, the right
to vote or to consent to any action of stockholders or to receive any notice of meetings of stockholders. 
 (b) Right to Cash
Payment. Each Holder of Stock Units representing Common Stock will be entitled to receive, upon the Company’s payment of a cash dividend on its outstanding shares of Common Stock, a cash payment for each such Stock Unit held by such Holder
as of the record date for such dividend which is equal to the per-share dividend paid on the outstanding shares of Common Stock.

 8. TRANSFERABILITY OF INCENTIVE AWARDS 
 Except as set forth in a Holder’s Agreement, or as the Board may otherwise agree, no Incentive Award held by such Holder may be transferred,
assigned, pledged or hypothecated, nor may such Incentive Award be made subject to execution, attachment or similar process. 
 9. RIGHTS
UPON TERMINATION OF EMPLOYMENT 
 If a Holder ceases to be an employee of the Company and its Affiliates other than because of death or
Disability, any Incentive Award held by such Holder that is not vested will vest or be forfeited by Holder in accordance with the terms of such Holder’s Agreement. 
 10. RIGHTS IN THE EVENT OF DEATH OR DISABILITY 
 If a Holder ceases to be an employee of the Company
and its Affiliates because of death or Disability, any Time-Vesting Incentive Award that is not vested will fully vest on the date of death or Disability. Upon such vesting upon a Holder’s death, the shares of Stock represented by the vested
Incentive Award will be deliverable in accordance with the terms of the Plan to the executors, administrators, legatees or distributes of such Holder’s estate. Any other Incentive Award held by such Holder that is not vested will vest or be
forfeited by Holder in accordance with the terms of such Holder’s Agreement 
 11. REQUIREMENTS OF LAW 
 We will not issue any shares of Stock under the Plan if doing so would result in a violation by us or anyone else of any law or regulation, including any
federal or state securities law or regulation. We are not obligated to register any shares of Stock or other securities covered by the Plan under the Securities Act. We are not obligated to take any action to cause shares of Stock issued or sold
because of the grant or vesting of Incentive Awards to comply with any law or regulation, including the Securities Act and the regulations thereunder. 
 12. AMENDMENT AND TERMINATION OF THE PLAN 
 The Board may amend, suspend or terminate the Plan. Except
as permitted under Section 13 below, no amendment, suspension or termination of the Plan will alter or impair any rights or obligations under any Incentive Award previously granted under the Plan without the Holder’s consent. With the
consent of a Holder, the Board may amend any Agreement with such Holder in a manner not inconsistent with the Plan. 
 Amendments to the Plan
will become effective when the Board adopts them.

 13. EFFECT OF CHANGES IN CAPITALIZATION 
 (a) Capitalization Change. If there is a Capitalization Change, we will adjust (i) the number and kinds of shares for which we may issue
Stock Units as provided in Section 3 above and (ii) the number and kind of shares for which Incentive Awards are outstanding as may be determined to be appropriate and equitable by the Board, in its sole discretion, to prevent dilution or
enlargement of existing rights. Without limiting the generality of the foregoing, we will use our reasonable efforts otherwise to adjust such outstanding Incentive Awards so that the proportionate interest of the Holder of such Incentive Awards
immediately after a Capitalization Change will be substantially the same as immediately before such Capitalization Change. Outstanding Incentive Awards representing shares of the Series A Preferred Stock or the Series B Preferred Stock will be so
adjusted if there is a Capitalization Change with respect to the Series A Preferred Stock or the Series B Preferred Stock, as the case may be. 
 (b) Reorganization in Which ITC^DeltaCom is the Surviving Corporation Not Involving a Corporate Transaction. If ITC^DeltaCom is the surviving corporation in any reorganization, merger or consolidation that is not a
Corporate Transaction, Incentive Awards will be adjusted so as to apply to the securities that a holder of the number and kind of shares of Stock subject to the Incentive Awards would have been entitled to receive immediately following such
reorganization, merger or consolidation. 
 (c) Reorganization in Which ITC^DeltaCom Is Not the Surviving Corporation or Involving a
Corporate Transaction. Upon the occurrence of any Corporate Transaction, (i) the Plan will terminate, unless ITC^DeltaCom or our Successor agrees in writing in connection with the Corporate Transaction to continue the Plan, and
(ii) unvested Incentive Awards will not vest or be forfeited in the case of such Corporate Transaction unless otherwise provided in the Agreement with respect to such Incentive Awards. 
 (d) Adjustments. The Board will make the adjustments to our Stock or securities under this Section 13, and the Board’s reasonable
determination in that respect will be final, binding and conclusive. Neither we nor any Successor will be required to issue any fractional shares of Stock or units of other securities, and any fractions resulting from any adjustment will be
eliminated in each case by rounding upward to the nearest whole share or unit. 
 (e) No Limitations on Company. The
grant of Incentive Awards pursuant to the Plan will not affect or limit in any way our right or power to make adjustments, reclassifications, reorganizations or changes of our capital or business structure or to merge, consolidate, dissolve or
liquidate, or to sell or transfer all or any part of our business or assets, without the consent of any Holder. 
 14. WITHHOLDING

 The Company or an Affiliate, as the case may be, has the right to deduct from payments of any kind otherwise due to a Holder any federal,
foreign, state or local taxes of any kind required by law to be withheld with respect to the vesting of or other lapse of 

 - 5 - 








 restrictions applicable to an Incentive Award or upon the issuance of any shares of Stock pursuant to an Incentive Award.
At the time of such vesting, lapse, exercise or issuance, the Holder will pay in cash to the Company or the Affiliate, as the case may be, any amount that the Company or the Affiliate may reasonably determine to be necessary to satisfy such
withholding obligation. Subject to the prior approval of the Company or the Affiliate, which may be withheld by the Company or the Affiliate, as the case may be, in its sole discretion, the Holder may elect to satisfy such obligations, in whole or
in part, (a) by causing the Company or the Affiliate to withhold shares of Stock otherwise issuable to the Holder or (b) by delivering to the Company or the Affiliate shares of Stock already owned by the Holder. The shares of Stock so
delivered or withheld will have an aggregate Fair Market Value equal to such withholding obligations. The Fair Market Value of the shares of Stock used to satisfy such withholding obligation will be determined by the Company or the Affiliate as of
the date that the amount of tax to be withheld is to be determined. A Holder who has made an election pursuant to this Section 14 may satisfy such Holder’s withholding obligation only with shares of Stock that are not subject to any
repurchase, forfeiture, unfulfilled vesting or other similar requirements. 
 15. DISCLAIMER OF RIGHTS 
 No provision in the Plan or in any Incentive Award granted pursuant to the Plan will be construed to confer upon any individual the right to remain in the
employ or service of the Company or any Affiliate, or to interfere in any way with our right and authority to terminate any employment or other relationship we have with any individual. Our obligation to pay any amounts or issue any Stock under the
Plan is only a contractual obligation to pay only those amounts, in the manner and under the conditions prescribed in the Plan and applicable Agreements. We are not required to transfer any amounts to a third party trustee or otherwise hold any
amounts in trust or escrow for payment to any participant or beneficiary under the Plan. 
 16. NONEXCLUSIVITY OF THE PLAN 

The Plan does not limit in any way the right and authority of the Board to adopt other incentive compensation arrangements that apply generally or that
are limited to single individuals, including arrangements providing for the award of unrestricted stock, restricted stock, stock units, stock options or stock appreciation rights.
