ELECTION OF DIRECTORS

Our Board of Directors is divided into three separate classes of directors, designated Class I, Class II and Class III, respectively. At each annual meeting of stockholders, the term of one class of directors expires and successors to such directors are elected to serve three-year terms. The terms of the Class I, Class II and Class III directors expire at the 2006, 2004 and 2005 annual meetings of the stockholders, respectively.

Pursuant to the Modified Plan and our Restated By-Laws, we are currently obligated to nominate for election (in connection with any meeting of or written consent solicited from our stockholders called for the purpose of electing directors) two individuals designated by Cerberus, two individuals designated by Huff and the individual acting as our Chief Executive Officer. The Chief Executive Officer is a Class I director, one designee of Cerberus and Huff, respectively, is a Class II director, and the other designee of Cerberus and Huff, respectively, is a Class III director. The election of directors is decided by the vote of the holders of a majority of the outstanding shares of all classes of the Company's stock entitled to vote, present in person or by proxy at the meeting, voting as a single class. In addition, Cerberus has the option to appoint one non-voting, non-participating observer to our Board of Directors.

DIRECTOR COMPENSATION

The Company compensates its non-employee directors $1,000 for attendance at in-person meetings of the Board of Directors and an annual fee of $26,000. Further, in February 2003, the Board approved a resolution authorizing the Company to pay a yearly fee of $25,000 to the chairman of both the Audit and Compensation Committees. Non-employee directors are also eligible to receive grants of options under the ICG Communications, Inc. Directors' Stock Option Plan.

EXECUTIVE EMPLOYMENT AGREEMENTS

The Company and its subsidiaries have employment agreements with Richard E. Fish, Jr., Michael D. Kallet, Bernard L. Zuroff, and John V. Colgan.

The Company's employment agreements with Richard E. Fish, Jr., Michael D. Kallet, Bernard L. Zuroff, and John V. Colgan provide for base salaries and such other benefits as are generally provided to senior executives, including reimbursement of reasonable out-of-pocket expenses incurred on behalf of the Company. These employment agreements may be terminated by the Company with or without

cause or by the employee upon the occurrence of a constructive dismissal (as defined therein). If an agreement is terminated by the Company for any reason other than the employee's death, disability or for cause, or if there is a constructive dismissal, the employee will receive an amount equal to twelve months' salary at the rate then in effect. Fifty percent will be paid in a lump sum within 15 days of termination and the remaining fifty percent is payable in twelve installments commencing 30 days after termination. If the employee obtains new employment within such twelve-month period, the severance is subject to mitigation on a dollar for dollar basis. If the employee's employment is terminated in the case of death, his estate will receive an amount equal to three months' base salary. Messrs. Fish, Kallet, Zuroff, and Colgan are subject to a ten-year confidentiality covenant and a one-year non-interference commitment following termination of employment.

The Company had an employment agreement with its former Chief Executive Officer, Randall E. Curran, which was terminated upon his departure from the Company in November 2003. In accordance with the terms of that Agreement, Mr. Curran was paid severance in an amount equal to 15 months salary. See "Executive Officer Compensation" table.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

None of our current executive officers has ever served as a member of the board of directors, or any committee thereof, of any other entity that has or has had one or more executive officers serving as a member of our Board of Directors, or any committee thereof.

Our Compensation Committee of our Board of Directors is comprised of our four non-employee directors: John A. Scarpati, who serves as Chairman, William J. Connors, Timothy F. Price and Joseph R. Thornton. None of the individuals serving on the Compensation Committee during fiscal year 2003 was an officer or employee of us or our subsidiaries during the fiscal year 2003, was an officer of us or our subsidiaries prior to the fiscal year 2003 or had any relationship that required disclosure under the caption "Certain Relationships and Related Transactions" contained herein.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Our Compensation Committee's responsibilities include:

•: The evaluation and implementation of fair, reasonable and competitive compensation practices for executive officers and other key employees of the Company based on the Company's established goals and objectives.
•: Oversight of broad-based employee compensation policies and programs.
•: Oversight of the Company's retirement and employee benefit plans.

Annual compensation for executives consists of base salary and performance-based bonuses. In general, the Company targets base salary levels for Company executives competitive with executives in peer companies. Typically, the performance award is based upon the Company's attainment of certain annual EBITDA targets. Payments are made only if financial performance meets or exceeds the threshold targets. The awards recognize and reward employees whose performance, contribution and skill promote the achievement of the Company's long-term financial and business objectives, align the interests of employees and stockholders, improve our earnings, and attract, motivate and retain employees. In fiscal year 2003, the targets were not met and no performance bonuses were awarded.

The Company also employs long-term equity incentives in the form of stock options. Stock options align the interests of employees and stockholders because they only have value if the stock price increases. The options have a term of ten years, are granted at the market price on the date of grant, and encourage employees' continued commitment to the Company's performance. Further, the Committee believes that options help retain key employees because such options typically vest over a

three-year period and are forfeited if the employee leaves the Company prior to vesting. Certain members of senior management have received stock option grants as of the Effective Date. See detailed information under the "Stock Option" heading.

The Company also has employment agreements with certain of its executive officers that provide for various other benefits. See "Executive Employment Agreements" for descriptions of those agreements. The Company's interim Chief Executive Officer, Mr. Jeffrey Pearl, does not have an employment agreement. Effective as of December 1, 2003, however, Mr. Pearl's annual base salary was increased by 33% from $300,000 to $400,000. The Committee believes the increase was reasonable light of Mr. Pearl assuming the additional duties of the office.

The Compensation Committee established the existing executive compensation program to encourage and reward management's efforts to strengthen the Company's business. The Company operates in a competitive marketplace and needs to retain well-qualified executive talent. Executive compensation is reviewed regularly to ensure compliance within existing guidelines and for competitiveness in the marketplace. Further, the Committee utilizes an outside consultant to review executive compensation and benefits provided to our executives.

The Compensation Committee has reviewed the compensation of the Company's executive officers and has concluded that their compensation is reasonable and appropriate. The Compensation Committee continually evaluates the compensation of the Company's executive officers, including an assessment of compensation reports for comparable companies and for the telecommunications industry in particular. The Compensation Committee believes that maintaining suitable executive compensation programs is necessary to support the future progress of the Company.

		William J. Connors Timothy F. Price John A. Scarpati Joseph R. Thornton

1.: The information regarding beneficial ownership of our common stock has been presented in accordance with the rules of the SEC and is not necessarily indicative of beneficial ownership for any other purpose. Under these rules, beneficial ownership of common stock includes any shares as to which a person, directly or indirectly, has or shares voting power or investment power and also any shares as to which a person has the right to acquire such voting or investment power within 60 days through the exercise of any stock option or other right. The percentage of beneficial ownership as to any person as of a particular date is calculated by dividing the number of shares beneficially owned by such person by the sum of the number of shares outstanding as of such date and the number of shares as to which such person has the right to acquire voting or investment power within 60 days. The number of shares of our common stock deemed outstanding on April 27, 2004 for purposes of calculating the percent of class owned was 8,000,000. As used in this registration statement, "voting power" is the power to vote or direct the voting of shares and "investment power" is the power to dispose or direct the disposition of shares. Except as noted,

each stockholder listed has sole voting and investment power with respect to the shares shown as beneficially owned by such stockholder.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Senior Subordinated Term Loan and Related Warrants

Pursuant to the Modified Plan, Cerberus arranged our $25 million senior subordinated term loan, all of the proceeds of which were distributed pro rata to the holders of our pre-petition secured notes. The senior subordinated term loan, which was prepaid pursuant to its terms following the completion of the Qwest transaction, had the following terms:

•: subordinated to the secured notes;
•: secured by liens, which were junior to the liens securing the then-outstanding secured notes, on substantially all of our assets;

•: 4-year maturity; and
•: interest rate of 14% per annum.

Madeleine L.L.C., a lender under the senior subordinated term loan, received warrants to purchase a total of 426,316 additional shares of common stock which are beneficially owned by Stephen Feinberg, a selling stockholder and the beneficial owner of more than 5% of our common stock. See "Security Ownership of Certain Beneficial Owners and Management." In addition, as a result of the Qwest transaction, we prepaid to Madeleine L.L.C. $22.5 million in principal and all accrued interest due to Madeleine L.L.C. under our senior subordinated term loan. See "Liquidity and Capital Resources—Prepayment of Secured Notes and Senior Subordinated Term Loan."

Nomination Rights to Board of Directors

Our Restated By-Laws, which were adopted in connection with the Modified Plan, provide that under certain conditions that are currently satisfied Huff and Cerberus and their respective affiliates each have the right to require us to nominate two individuals for election to our Board of Directors. Further, Cerberus has the right to appoint one non-voting, non-participating observer to our Board of Directors. Accordingly, Cerberus required us to nominate Timothy F. Price and John A. Scarpati, and both were elected and currently serve as members of our Board of Directors. Huff required us to nominate William J. Connors and Joseph R. Thornton, and both were elected and currently serve as members of our Board of Directors. Mr. Connors and Mr. Thornton are both currently employed by Huff. Furthermore, in connection with the Modified Plan, we entered into a letter agreement with Huff, dated as of July 25, 2002, pursuant to which Huff will cause one or more of the individuals who were nominated for election to our Board of Directors by Huff, as described above, to resign from our Board of Directors upon a specified reduction in the percentage of our common stock that they control. See "Executive Compensation—Election of Directors."

Registration Rights Agreement

Madeleine L.L.C. and Huff entered into a registration rights agreement with us at the time of our emergence from bankruptcy which gives them certain registration rights with respect to the shares of our common stock owned by them.

Under the terms of the registration rights agreement, the above holders are entitled to demand up to five total registrations with respect to our securities, provided the securities to be registered in any such registration either equal a minimum of $5,000,000 aggregate offering price to the public or the requested registration constitutes all of such holder's registrable securities. We are required to register all shares of our common stock currently owned or subsequently acquired by these holders. The registration rights agreement also provides these holders with unlimited "piggyback" registration rights for securities owned by them, which gives them the right to include the securities they own in registration statements in which we are registering securities for sale on our behalf or on behalf of other holders of our securities. Although we will be responsible for all expenses incurred in connection with any registration offered pursuant to the registration rights agreement, we will not be responsible for applicable underwriting discounts, selling commissions or stock transfer taxes incurred by the holders or for the expenses of more than one counsel for all such holders. The registration rights agreement also includes customary indemnification and contribution provisions.

Indemnification Agreements

In March of 2003, we entered into indemnification agreements with each of our directors. The indemnification agreements require us to indemnify our directors to the fullest extent permitted by law and require us to advance the expenses incurred by such directors as a result of any threatened claims or proceedings brought against them as to which they could be indemnified, subject to applicable law.

ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES

Pre-Approval Policies and Procedures

The Audit Committee of our Board of Directors is responsible for the appointment, compensation and oversight of the work of our independent public accountant. Pursuant to the Audit Committee's charter, the Audit Committee pre-approves all auditing and permissible non-auditing services provided by our independent auditor. Approval of audit and permissible non-audit services may also be delegated to one or more designated members of the Committee, and the person(s) granting such approval is required to report such approval to the full Committee at the next scheduled meeting.

Independent Auditor Fees

We have engaged KPMG LLP to be our independent accountant. Fees billed to the Company by KPMG LLP for services rendered during fiscal year 2002 and 2003 were as follows:

	2002		2003
	(in thousands)
Audit fees:(1)	$	562,000	$	534,000
Audit-related fees:(2)		202,000		—
Tax fees:(3)		264,000		159,000
All other fees:(4)		30,000		—

For purposes of the preceding table, the professional fees are classified as follows:

(1): Audit Fees—These fees were for professional services performed for the audit of our annual financial statements and review of our quarterly financial statements included in our Form 10-Q filings, services that are normally provided by our independent accountant in connection with statutory and regulatory filings or engagements, and services that generally only our independent accountant reasonably can provide, such as comfort letters, statutory audits, attest services, consents and assistance with and review of documents filed with the SEC.
(2): Audit-related fees were primarily related to KPMG LLP's consultations with the Company in regard to the implementation of new accounting methods, including Fresh Start reporting, and for other services related to the Company's filing and emergence from Chapter 11 bankruptcy.
(3): Tax Fees—These are fees for all professional services performed by professional staff in our independent accountant's tax division, except those services related to the audit of our financial statements. These include fees for tax compliance, tax planning and tax advice.
(4): Other fees relate to non-auditing support services provided in conjunction with the Company's bankruptcy proceedings, including assistance with bankruptcy filings and responding to information requests by the Company's creditors and the Company's unsecured Creditors' Committee.

SEC rules effective as of May 6, 2003 require our Audit Committee to pre-approve all auditing and permissible non-auditing services provided by our independent auditor (with certain limited exceptions). Since the effective date of these rules, our Audit Committee approved in advance all of the services performed by KPMG LLP, as described above.
