                             INTRODUCTORY STATEMENT

         This Amendment No. 1 to Schedule TO amends and supplements the Tender
Offer Statement on Schedule TO filed by Sorrento Networks Corporation with the
Securities and Exchange Commission on April 3, 2002 (the "Schedule TO") relating
to our offer to our employees and to employees of our subsidiaries to exchange
outstanding options to purchase our common stock, par value $0.30 per share,
having an exercise price greater than or equal to $7.50 per share for FIBR
options and all outstanding options of our subsidiary, Sorrento Networks Inc.
("SNI"), granted under the Sorrento Networks Corporation 1988 Stock Option Plan
(the "1988 Plan"), the Amended and Restated 1997 Incentive and Non-Qualified
Stock Option Plan (the "1997 Plan"), the Sorrento Networks Corporation 2000
Stock Incentive Plan (the "2000 Plan"), the Sorrento Networks Inc. 2000 Stock
Option/Stock Issuance Plan (the "SNI Plan") (collectively with the 1988 Plan,
1997 Plan and the 2000 Plan, the "Plans") for new nonqualified stock options
with a new exercise price (the "New Options").

         Employees who were granted stock options on or after October 1, 2001,
even if those options have an exercise price greater than $7.49 per share for
FIBR options or if those options are SNI options, may not participate in the New
Grant Program. Current and former directors and executive officers (within the
meaning of Rule 16a-1(f) promulgated under the Securities Exchange Act of 1934,
as amended) and key management as well as independent contractors, advisory
board members and other non-employees of ours or of our subsidiaries are not
eligible to participate in the New Grant Program.

         "Non-plan" option grants, previously included in this offer to exchange
options, are now excluded from this offer. Accordingly, we are extending the
offer to exchange outstanding stock options under the Plans. This offer will now
remain open until 5:00 p.m. Pacific Time on May 17, 2002.

         We are changing the fax number to which elections to exchange grants of
stock options should be delivered. The new number is (858) 450-4947. If you have
already submitted your Letter of Transmittal (Election to Participate), you do
not need to do anything further.

ITEM 1. SUMMARY TERM SHEET

         The reference to the inclusion of certain "non-plan" options in this
Offer to Exchange, contained in the Summary Term Sheet under the introduction
and under section 2 ("What securities are we offering to exchange?") is hereby
deleted and the following information is hereby substituted in its stead:

                  "Non-plan" options are excluded from this offer to exchange
         stock options.

         The information contained in the Summary Term Sheet under the
introduction and under sections 3 ("Why is Sorrento Networks corporation
implementing the New Grant Program?"), 13 ("What will happen if I do not turn in
my form by the deadline?"), and 30 ("What will be the share amount of the new
options?") is hereby supplemented by the inclusion of the following

                                       3







information after each reference therein to the conversion ratio of 1 FIBR share
for every 3.9 SNI shares:

                  Upon conversion of SNI option grants into FIBR option grants,
         the exercise price of the converted FIBR option grant is equal to the
         exercise price of the SNI option grant multiplied by 3.9. For example,
         an employee who tenders an option to purchase 3.9 shares of SNI stock
         at an exercise price of $5.45 per share will receive an option to
         purchase 1 share of FIBR stock with an exercise price of $21.25.

         The information contained in the Summary Term Sheet under section 13
("What will happen if I do not turn in my form by the deadline?") is hereby
supplemented by the inclusion of the following information before the last
sentence:

                  Supplemental option grants equal to 10% of the equivalent
         number of FIBR options that are made to employees who elect not to
         participate in this offer to exchange will vest at the rate of 25%
         every three months for one year in total.

         The information contained in the Summary Term Sheet under the following
sections:

                  section 4 ("What do I need to do to participate in the New
                  Grant Program?");
                  section 11 ("If I decide to participate in the New Grant
                  Program, what will happen to my current options?");
                  section 12 ("What is the deadline to participate in the
                  New Grant Program, and how do I participate?");
                  section 14 ("How do I withdraw from the New Grant Program
                  after I have submitted a Letter of Transmittal (Election to
                  Participate)?");
                  section 15 ("During what period of time may I withdraw a
                  previous election to participate in the New Grant Program?");
                  section 20 ("What if my employment at Sorrento Networks
                  Corporation ends between the date of this Offer to Exchange
                  and the replacement grant date?");

                  Program, what will happen to my options that will be
                  cancelled?");
                  section 29 ("When will we grant the new options?"); and
                  section 38 ("What do I need to do to participate in the New
                  Grant Program?")

is hereby amended to change the date on which this Offer to Exchange expires to
5:00 p.m. Pacific Time on May 17, 2002 and also to change the fax number to
which Letters of Transmittal (Election to Participate) should be sent. The new
fax number is (858) 450-4947. If you have already submitted your Letter of
Transmittal (Election to Participate), you do not need to do anything further.

and section 2 ("What securities are we offering to exchange?") is hereby deleted
and the following information is hereby substituted in its stead:

         The Summary Term Sheet and Section 3 are hereby supplemented by the
inclusion of the following information:

         Supplemental option grants equal to 10% of the equivalent number of
         FIBR options that are made to employees who elect not to participate in

         at an exercise price of $5.45 per share will receive an option to
         purchase 1 share of FIBR stock with an exercise price of $21.25.

         The information contained in the Summary Term Sheet, and in Sections 3
(Procedures for Electing to Participate in the New Grant Program") is hereby
amended to change the fax number to which Letters of Transmittal (Election to

         The information set forth in the Offer to Exchange under Section 16

                  In addition, you should review any amendments to our Schedule
         TO and the Offer to Exchange that was filed with the SEC, including,
         among other things, the information contained in Amendment No. 1 to the
         Schedule TO, and delivered to you as an Amendment to the Offer to
         Exchange.

ITEM 6. PURPOSES OF THE TRANSACTION AND PLANS OR PROPOSALS

         The information set forth in the Offer to Exchange under Section 2
(Purpose of the New Grant Program) is hereby amended to read as follows:

         We issued the options outstanding under the Plans to provide our
employees an opportunity to acquire or increase their ownership stake in
Sorrento Networks Corporation, creating a stronger incentive to expend maximum
effort for our growth and success and encouraging our employees to continue
their employment with us.

         Many of these options, whether or not they are currently exercisable,
have exercise prices that are significantly higher than the current market price
of our common stock. We are implementing the New Grant Program to provide our
employees with the opportunity to own options that over time may have a greater
potential to increase in value, which we hope will create better performance
incentives for employees and will maximize the value of our common stock for our
current stockholders.

         Because of the number of options currently outstanding, a grant of
additional options to all Sorrento Networks Corporation employees holding
out-of-the-money options could be significantly dilutive to our current and
future stockholders and could potentially have a negative impact on our
outstanding shares and earnings per share.

CONSIDERING THE RISKS ASSOCIATED WITH THE VOLATILE AND UNPREDICTABLE NATURE OF
THE STOCK MARKET, THE TECHNOLOGY SECTOR AND OUR INDUSTRY IN PARTICULAR, THERE IS
NO GUARANTEE THAT THE CLOSING MARKET PRICE OF OUR COMMON STOCK ON THE
REPLACEMENT GRANT DATE (AND THEREFORE THE EXERCISE PRICE OF ANY NEW OPTION) WILL
BE LESS THAN OR EQUAL TO THE EXERCISE PRICE OF YOUR EXISTING OPTION, OR THAT
YOUR NEW OPTION WILL INCREASE IN VALUE.

         We are continuing our negotiations with the holders of SNI's Series A
Convertible

                                       6







Preferred Stock but have not reached an agreement with them. On an "as
converted" basis, the shares of Series A Convertible Preferred Stock represent
approximately 14% of the outstanding shares of SNI. The terms of a settlement
with the holders of such shares of Preferred Stock may include a requirement
that we issue a significant and material quantity of our equity securities or
securities that are convertible into our common stock.

         Subject to the foregoing, and except as otherwise disclosed in this
Offer to Exchange, we currently have no plans or proposals that relate to or
would result in:

          o    an extraordinary transaction, such as a merger, reorganization or
               liquidation, involving us or any of our subsidiaries that is
               material to us (however, we expect to consider such matters from
               time to time);
          o    any purchase, sale or transfer of a material amount of our assets
               or the assets of any of our subsidiaries;
          o    any material change in our present dividend rate or policy, or
               our indebtedness or capitalization;
          o    any other material change in our corporate structure or business;
          o    our common stock not being authorized for quotation in an
               automated quotation system operated by a national securities
               association;
          o    our common stock becoming eligible for termination of
               registration pursuant to Section 12(g)(4) of the Securities
               Exchange Act;
          o    the suspension of our obligation to file reports under Section
               15(d) of the Securities Exchange Act;
          o    the acquisition by any person of any of our securities or the
               disposition of any of our securities (other than as a result of
               the exercise of stock options issued under the Plans or purchases
               made under our employee stock purchase plan) in an amount that is
               material to us; or
          o    any changes in our certificate of incorporation, bylaws of other
               governing instruments or any actions that could impede the
               acquisition of control of us.

         Neither we nor our Board of Directors makes any recommendation as to
whether you should elect to participate in the New Grant Program, nor have we
authorized any person to make any such recommendation. We urge you to evaluate
carefully all of the information in this Offer to Exchange and to consult your
own investment and tax advisors. You must make your own decision whether to
elect to participate in the New Grant Program.
