----------
(1)   The amount shown on this table represents hypothetical gains that could be
      achieved for the respective options, if exercised at the end of the option
      term. These gains are based on assumed rates of stock price appreciation
      of 5% and 10% compounded annually from the date the respective options
      were granted to their expiration date. The gains shown are net of the
      option exercise price, but do not include deductions for taxes or other
      expenses associated with the exercise. Actual gains, if any, on stock
      option exercises will depend on the future performance of the Common
      Stock, the option holder's continued employment through the option period,
      and the date on which the options are exercised. These amounts are not
      intended to forecast possible future appreciation, if any, of the
      Company's stock price.

(2)   Options granted June 28, 2001. Options have a two-year vesting schedule,
      vesting 50% on the first anniversary of grant and 50% on the second
      anniversary of the grant, except for such earlier vesting permitted under
      the terms of the Amended and Restated Stock Incentive Plan.

(3)   Options granted June 28, 2001.  Options were completely vested upon grant.

The following table sets forth the number of shares acquired on exercise of
stock options and the aggregate gains realized on exercise in 2001 by the Named
Executive Officers. The table also sets forth the number of shares covered by
exercisable and unexercisable options held by such executives on December 31,
2001 and the aggregate gains that would have been realized had these options
been exercised on December 31, 2001, even though these options were not
exercised, and the unexercisable options could not have been exercised, on
December 31, 2001.

In June 2001 the shareholders of the Company approved and ratified stock option
plans for the Company's wholly-owned subsidiaries, Aegean Networks, Incorporated
and Centauri Netsystems Corporation. The Stock Option Committee subsequently
approved preliminary grants of options under these plans for stock intended to
approximate 6% to 8% of the equity of these entities to be issued to all of our
employees, including approximately 3.7% related to the Company's executive
officers. Per the option agreements, rights to these options could not vest
until the "initial funding" of the related project. This initial funding has not
occurred. Effective December 31, 2001 the Company terminated these plans, and
the majority of the preliminary option grants, including those related to the
Company's executive officers, have been cancelled.

or if he terminates "without good reason"), all unvested stock options issued
and outstanding shall vest upon such termination.

In the event of a termination by the Company for "cause" (as defined in the
agreement) or by Mr. Frietsch "without good reason", then the Company's
obligation to pay compensation and benefits shall terminate as of that date,
other than for salary and benefits already accrued. In the event of termination

reason" (e.g., a material breach of the employment agreement by the Company, a
material change in the nature or scope of his authority and duties, his salary
is reduced, bonus eligibility is denied or required compensation payments are
not made), then the Company shall pay Mr. Frietsch as severance pay, at Mr.
Frietsch's option, in accordance with the general payroll practices of the
Company or in a lump sum payment, the greater of (i) $1,000,000 or (ii) the sum

is terminated upon or following within twelve months of a "change in control",
the Company shall pay as severance pay and as liquidated damages, at Mr.
Frietsch's option the greater of (i) the sum of three years of his base salary
and (ii) $1,000,000. In the event of termination for disability or death, then
Mr. Frietsch or his estate, as the case may be, is entitled to receive payments

or in a lump sum payment. Mr. Frietsch is entitled to a gross-up payment to
compensate for any excise taxes imposed.

2001, which provides for his continued employment as Executive Vice President
and Corporate Development Officer. Pursuant to the arrangement, Dr. Helms is to
receive a base salary of $225,000 per year. The term of the arrangement extends
through January 1, 2004 and is automatically renewed for subsequent one-year

provisions of the agreement. The Company may terminate Dr. Helms for disability,
cause, without cause, and for death or disability, and Dr. Helms may terminate
the agreement for good reason and without good reason ( as defined in the
agreement). In the event of Dr. Helms' disability, as defined, the Company has

ITEM 12 - SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information as of April 23, 2002, unless
otherwise noted, with respect to the beneficial ownership of the Company's
Common Stock by (i) each person known by the Company to own beneficially more
than 5% of the outstanding Common Stock; (ii) each director and nominee for
director; (iii) each executive officer named in the Summary Compensation Table
under the heading "Executive Compensation" below; and (iv) all directors and
executive officers of the Company as a group. Unless otherwise indicated, the
information included below is based upon the Company's stock transfer records as
maintained by the Company's stock transfer agent.

The number of shares of Common Stock beneficially owned by each director or
executive officer is determined pursuant to the rules of the Securities and
Exchange Commission (the SEC), and the information is not necessarily indicative
of beneficial ownership for any other purpose. Under the SEC's rules, an
individual beneficially owns any shares as to which the individual has sole or
shared voting power or investment power and, any shares, which the individual
has the right to acquire through the exercise of any stock option or other right
within the next 60 days. Unless otherwise indicated, each person has sole
investment and voting power (or shares such power with his or her spouse) with
respect to the shares set forth in the following table. The inclusion herein of
any shares deemed beneficially owned does not constitute admission of beneficial
ownership of those shares.

ITEM 13 - CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

On April 11, 2002, we agreed to issue 1,000,000 shares of Common Stock to The
Coastal Corporation Second Pension Trust ("Coastal") in exchange for the return
and cancellation of warrants for the purchase of 6,517,308 shares of Common
Stock that Coastal held. The 1,000,000 shares of Common Stock will be deemed
restricted under federal securities laws; however, we have agreed to register
these shares with the SEC so Coastal may resell them without restriction.

On April 11, 2002 we agreed to issue 1,000,000 shares of Common Stock to St.
James Capital Partners, L.P. and SJMP, L.P. (collectively "St. James") in
exchange for the return and cancellation of warrants for the purchase of
19,500,000 shares of Common Stock. We also agreed to issue 3,000,000 additional
shares to St. James if our Common Stock trades at a price of $0.75 or more for a
period of ten consecutive trading days before October 14, 2002. These shares
will be deemed restricted under federal securities laws; however, we have agreed
to register these shares with the SEC so St. James may resell them without
restriction.

The Company is obligated to Mr. Frietsch under a demand note with a principal
amount of $100,000. The note bears interest at prime plus 3%. Accrued and unpaid
interest amounted to approximately $45,000 as of December 31, 2001. The note and
accrued interest is convertible into Common Stock at the option of Mr. Frietsch
at a rate of $1.00 per share.
