                                     PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

     Avocent Corporation, formerly known as Aegean Sea Inc., ("Avocent") hereby
incorporates by reference in this registration statement the following documents
which were previously filed with the Securities and Exchange Commission:

     (a)  Avocent's Registration Statement on Form S-4 (No. 333-33768) filed
          March 31, 2000, as amended.

     (b)  The description of Avocent's Common Stock contained in its
          Registration Statement on Form 8-A, filed May 9, 2000 pursuant to
          Section 12(g) of the Securities Exchange Act of 1934.

     All documents subsequently filed by Avocent pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, prior to the filing
of a post-effective amendment to this registration statement which indicates
that all securities offered hereby have been sold or which deregisters all
securities remaining unsold, shall be deemed to be incorporated by reference in
this registration statement and to be a part hereof from the date of filing of
such documents.

ITEM 4. DESCRIPTION OF SECURITIES.

     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by current law.

     Article XI of Avocent's Certificate of Incorporation provides for the
indemnification of directors to the fullest extent permissible under Delaware
General Corporation law.

     Article VI of Avocent's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the corporation to the
fullest extent permissible under the Delaware General Corporation Law.

     Avocent has entered into indemnification agreements with its directors and
executive officers, in addition to the indemnification provided for in Avocent's
Certificate of Incorporation and Bylaws, and intends to enter into
indemnification agreements with any new directors and executive officers in the
future.


                                      -2-
<PAGE>

     In addition, pursuant to the terms of the Agreement and Plan of
Reorganization by and among Avocent, Apex Inc., a Washington corporation and
Cybex Computer Products Corporation, an Alabama corporation, dated as of March
8, 2000, Avocent has agreed to fulfill and honor in all respects the obligations
of Apex and Cybex pursuant to any indemnification agreements between Apex and
Cybex and their directors and officers as of March 8, 2000 and any
indemnification provisions under Apex's and Cybex's Articles of Incorporation or
Bylaws as in effect immediately prior to the merger. In connection with the
reorganization, Apex and Cybex each became a wholly-owned subsidiary of Avocent
by merging with wholly-owned subsidiaries of Avocent. The Articles of
Incorporation and Bylaws of these wholly-owned subsidiaries contain provisions
with respect to exculpation and indemnification that are at least as favorable
to the parties to the indemnification agreements as those contained in the
Articles of Incorporation and Bylaws of Apex and Cybex, respectively, as in
effect immediately prior to the merger. The provisions will not be amended,
repealed or otherwise modified for a period of six years from March 8, 2000 in
any manner that would adversely affect the rights thereunder of individuals who,
immediately prior to March 8, 2000, were directors, officers, employees or
agents of Apex and Cybex, respectively, unless such modification is required by
law.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling Avocent
pursuant to the foregoing provisions, Avocent has been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is
therefore unenforceable.

ITEM 9. UNDERTAKINGS.

     (a)  RULE 415 OFFERING

     Avocent hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement;

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  FILING INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE

     Avocent hereby undertakes that, for purposes of determining any liability
under the Securities Act of 1933, each filing of Avocent's annual report
pursuant to section 13(a) or section 15(d) of the


                                      -4-
<PAGE>

Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the Exchange
Act) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (c)  REQUEST FOR ACCELERATION OF EFFECTIVE DATE OR FILING OF REGISTRATION
          STATEMENT ON FORM S-8

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
Avocent pursuant to the foregoing provisions, or otherwise, Avocent has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of Avocent in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, Avocent will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

     Avocent Corporation, formerly known as Aegean Sea Inc., ("Avocent") hereby
incorporates by reference in this registration statement the following documents
which were previously filed with the Securities and Exchange Commission:

     (a)  Avocent's Registration Statement on Form S-4 (No. 333-33768) filed
          March 31, 2000, as amended.

     (b)  The description of Avocent's Common Stock contained in its
          Registration Statement on Form 8-A, filed May 9, 2000 pursuant to
          Section 12(g) of the Securities Exchange Act of 1934.

     All documents subsequently filed by Avocent pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, prior to the filing
of a post-effective amendment to this registration statement which indicates
that all securities offered hereby have been sold or which deregisters all
securities remaining unsold, shall be deemed to be incorporated by reference in
this registration statement and to be a part hereof from the date of filing of
such documents.

ITEM 4. DESCRIPTION OF SECURITIES.

     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by current law.

     Article XI of Avocent's Certificate of Incorporation provides for the
indemnification of directors to the fullest extent permissible under Delaware
General Corporation law.

     Article VI of Avocent's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the corporation to the
fullest extent permissible under the Delaware General Corporation Law.

     Avocent has entered into indemnification agreements with its directors and
executive officers, in addition to the indemnification provided for in Avocent's
Certificate of Incorporation and Bylaws, and intends to enter into
indemnification agreements with any new directors and executive officers in the
future.

                                      -2-
In addition, pursuant to the terms of the Agreement and Plan of
Reorganization by and among Avocent, Apex Inc., a Washington corporation and
Cybex Computer Products Corporation, an Alabama corporation, dated as of March
8, 2000, Avocent has agreed to fulfill and honor in all respects the obligations
of Apex and Cybex pursuant to any indemnification agreements between Apex and
Cybex and their directors and officers as of March 8, 2000 and any
indemnification provisions under Apex's and Cybex's Articles of Incorporation or
Bylaws as in effect immediately prior to the merger. In connection with the
reorganization, Apex and Cybex each became a wholly-owned subsidiary of Avocent
by merging with wholly-owned subsidiaries of Avocent. The Articles of
Incorporation and Bylaws of these wholly-owned subsidiaries contain provisions
with respect to exculpation and indemnification that are at least as favorable
to the parties to the indemnification agreements as those contained in the
Articles of Incorporation and Bylaws of Apex and Cybex, respectively, as in
effect immediately prior to the merger. The provisions will not be amended,
repealed or otherwise modified for a period of six years from March 8, 2000 in
any manner that would adversely affect the rights thereunder of individuals who,
immediately prior to March 8, 2000, were directors, officers, employees or
agents of Apex and Cybex, respectively, unless such modification is required by
law.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling Avocent
pursuant to the foregoing provisions, Avocent has been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is
therefore unenforceable.

ITEM 9. UNDERTAKINGS.

     (a)  RULE 415 OFFERING

     Avocent hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement;

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  FILING INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE

     Avocent hereby undertakes that, for purposes of determining any liability
under the Securities Act of 1933, each filing of Avocent's annual report
pursuant to section 13(a) or section 15(d) of the

                                      -4-
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the Exchange
Act) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (c)  REQUEST FOR ACCELERATION OF EFFECTIVE DATE OR FILING OF REGISTRATION
          STATEMENT ON FORM S-8

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
Avocent pursuant to the foregoing provisions, or otherwise, Avocent has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of Avocent in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, Avocent will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

                                      -5-
