                                 FIRST AMENDMENT

This First Amendment to the Services Agreement No. 01-02-203 ("Amendment") made
by and between George Reyes and ONI Systems Corp. is entered into as of the 9th
day of April 2002 (the "Amendment Effective Date") by George Reyes
("Contractor") and ONI Systems Corp. ("ONI").

                                    RECITALS

A.      The parties have previously entered into the Services Agreement No.
        01-02-203 ("Agreement"), effective as of January 24, 2002.

B.      The parties desire to amend the Agreement in order to extend its Term as
        provided below.

Accordingly, the parties agree as follows:

        1.      The terms used in this Amendment shall have the same meanings as
                set out in the Agreement.

        2.      Section 1 of the Statement of Work is hereby deleted in its
                entirety and replaced with the following:

                Contractor shall, consistent with the terms of this Agreement,
                perform services for, and on behalf of ONI for the three (3)
                month period following the Effective Date ("Initial Term"),
                which shall be automatically renewed for successive one (1)
                month periods ("Renewal Period") unless either party provides
                thirty (30) days prior written notice of its intent not to renew
                (collectively, "Term").

        3.      Section 3 of the Statement of Work should be modified by the
                insertion of the following at the end of the provision:

                As consideration for Services rendered by Contractor during any
                Renewal Period following the Initial Term, ONI will pay
                Contractor twenty thousand dollars ($20,000) and grant
                Contractor a stock option to purchase eight thousand (8,000)
                shares of ONI's common stock with an exercise price equal to the
                fair market value on the date of grant. The stock option(s) must
                be approved by ONI's Board of Directors. The option(s) will vest
                and become exercisable upon the monthly anniversary of the
                Effective Date. Vesting will depend upon Contractor continuing
                to provide Services to ONI for each Renewal Period. Contractor
                will be able to exercise the option for a period of one (1) year
                following the date on which Contractor ceases to provide
                Services to ONI, provided that the option may not be exercised
                more than ten (10) years after the date of grant. The option
                will be subject to the terms of ONI's 2000 Equity Incentive Plan
                and a Stock Option Agreement between Contractor and ONI.

        4.      This Amendment shall prevail and control with respect to any
                inconsistency between the terms of this Amendment and the terms
                of the Agreement. Except as specifically provided by this
                Amendment, the Agreement shall continue in full force and effect
                in accordance with its terms. This Amendment shall be effective
                as of the Amendment Effective Date set forth above.

        In witness whereof, the parties have caused this Amendment to be
executed by their respective authorized representatives.

                                     Keith A. Zar, Secretary

                                    EXHIBIT A

                      Series A Convertible Preferred Stock

A. DESIGNATION OF SHARES; REGISTER

           There is hereby designated 9,000,000 shares of the Preferred Stock of
the Company as Series A Convertible Preferred Stock ("Series A Preferred
Stock"). Each share of Series A Preferred Stock shall have a par value of $0.01
per share. The Company shall register shares of the Series A Preferred Stock in
records to be maintained by the Company for that purpose (the "Preferred Stock
Register"), in the name of the record holders thereof from time to time. The
Company may deem and treat the registered holder of shares of Series A Preferred
Stock as the absolute owner thereof for the purpose of any conversion hereof or
any distribution to such holder, and for all other purposes, absent actual
notice to the contrary. The Company shall register the transfer of any shares of
Series A Preferred Stock in the Preferred Stock Register, upon surrender of
properly endorsed certificates evidencing such shares to the Company. Upon any
such registration or transfer, a new certificate evidencing the shares of Series
A Preferred Stock so transferred shall be issued to the transferee and a new
certificate evidencing the remaining portion of the shares not so transferred,
if any, shall be issued to the transferring holder.

B. PREFERRED STOCK

        1. DIVIDENDS

           a. The holders of the Series A Preferred Stock shall be entitled to
receive, when, as and if declared by the Company's Board of Directors, but only
out of any funds legally available therefor, cumulative dividends at an annual
rate of 7.5% of the Purchase Price (as defined below) per outstanding share of
Series A Preferred Stock. Such dividends shall accrue whether or not they have
been declared and whether or not there are profits, surplus or other

                                       2
<PAGE>

funds of the Company legally available for the payment of dividends. Dividends
paid under this Section B.1. shall be payable prior and in preference to any
dividend (payable other than in Common Stock) on the Common Stock of the
Company. So long as any Preferred Stock is outstanding, (i) the Company shall
not, directly or indirectly, redeem, purchase or otherwise acquire any Common
Stock or set aside any monies for such a redemption, purchase or other
acquisition, and (ii) the Company shall not pay or declare any dividend or make
any distribution on any Common Stock, except stock dividends on the Common Stock
payable in additional shares of Common Stock. The Company may elect to pay such
dividends on the Series A Preferred Stock under Section B.1. in additional
shares of Series A Preferred Stock valued at the Purchase Price. If the Company
elects to pay such dividends in additional shares of Series A Preferred Stock,
such additional shares shall be validly issued and nonassessable and, upon
issuance, shall have rights identical to the outstanding shares of Series A
Preferred Stock.

           b. The amount of dividends payable for any period that is shorter or
longer than a full annual dividend period shall be computed on the basis of a
360-day year and the actual number of days elapsed (including the first day but
excluding the last day) occurring in the period for which such amount is
payable. If a dividend cannot be paid in full, then such dividends shall be
paid, to the maximum possible extent, to the Record Holders (as defined below),
ratably based on the respective amount of such dividend otherwise payable to
them.

        2. LIQUIDATION PREFERENCE

           a. If the Company proposes to consummate a Liquidation Event (as
defined below), after paying or providing for payment of its debts and other
liabilities, the Company shall, before paying any amount to the holders of the
Company's Common Stock, pay to the Record Holders their Series A Preference for
each outstanding share of Series A Preferred Stock.

           b. The "Series A Preference" is the amount for each outstanding share
of Series A Preferred Stock equal to the Liquidation Price (as defined below).

           c. If the Company's assets to be distributed among the Record Holders
on a Liquidation Event are insufficient to permit the Company to pay the full
Series A Preference for each outstanding share of Series A Preferred Stock, the
Company shall distribute its assets among the Record Holders ratably based on
the respective amounts otherwise payable to them.

           d. Thereafter, the remaining assets of the Company shall be
distributed to holders of the Common Stock.

           e. The Company shall pay all amounts due to the Record Holders under
this Section B.2. by the closing of such Liquidation Event.

        3.  OPTIONAL REDEMPTION

           a. Redemption Right of Holder. Record Holders owning a majority of
the shares of Series A Preferred Stock issued and outstanding at such time shall
have the right, by delivery of written notice to the Company (the "Demand
Notice"), to require the Company to redeem their shares of Series A Preferred
Stock at the Redemption Price (as defined below) per share, on or after February
19, 2007 (the "Redemption Date"). The Company shall within ten

                                       3
<PAGE>

days of receipt of the Demand Notice send notice (the "Redemption Notice") to
each other Record Holder, granting such Record Holders the option to have their
shares of Series A Preferred Stock repurchased by the Company at the Redemption
Price. Each Record Holder which elects to have their shares of Series A
Preferred Stock repurchased by the Company shall notify the Company within 20
days of such Record Holder's receipt of the Redemption Notice (the "Election
Notice").

           b. Closing. Within sixty (60) days after the Redemption Date, the
Company will purchase, and the electing Record Holders will sell, the Series A
Preferred Stock requested to be purchased in the Demand Notice or the Election
Notice and requested to be included in the redemption pursuant to Section
B.3.a., at a time and place mutually agreeable to the Company and the electing
Record Holders owning a majority of the Series A Preferred Stock to be
repurchased (the "Redemption Closing"). At the Redemption Closing, the electing
Record Holders shall deliver to the Company certificates representing such
Record Holders' shares of Series A Preferred Stock to be repurchased by the
Company, and the Company shall pay to each such Record Holder the applicable
Redemption Price by a cashier's or certified check or by wire transfer in
immediately available funds.

           c. Effect of Redemption. From and after the Redemption Closing,
unless there shall have been a default in payment of the consideration to be
provided in such redemption, all rights of the holders of such shares as holders
of the Series A Preferred Stock to be redeemed shall cease with respect to such
shares, and such shares shall not thereafter be transferred on the books of the
Company or be deemed to be outstanding for any purpose whatsoever. Subject to
the rights of additional series of Preferred Stock which may from time to time
come into existence, if the funds of the Company legally available for
redemption of shares of Series A Preferred Stock at the Redemption Closing are
insufficient or are not permitted to be used under any financing agreement to
redeem the total number of shares of Series A Preferred Stock to be redeemed,
those funds which are legally available will be used to redeem the maximum
possible number of such shares ratably among such holders based upon such
holders aggregate holdings of Series A Preferred Stock. The shares of Series A
Preferred Stock not redeemed shall remain outstanding and entitled to all the
rights and preferences provided herein, including, without limitation, the right
to make subsequent redemption requests.

        4. VOLUNTARY CONVERSION

           Each share of Series A Preferred Stock shall have the following
conversion rights (the "Conversion Rights"):

           a. Conversion Option. Each Record Holder may, at such Record Holder's
option at any time and from time to time, convert any or all of its shares of
Series A Preferred Stock into the number of fully paid and nonassessable shares
of Common Stock determined pursuant to Section B.4.b.

           b. Conversion Price. Each share of Series A Preferred Stock shall be
convertible into such number of fully paid and nonassessable shares of Common
Stock as is determined by dividing (x) the Purchase Price plus cumulative
accrued and unpaid dividends, if any, by (y) the Conversion Price (as defined
below) in effect on the date the certificate is

                                       4
<PAGE>

surrendered for conversion. The initial Conversion Price per share for shares of
Series A Preferred Stock shall be one-half of the Purchase Price (the
"Conversion Price"). The Conversion Price shall be subject to adjustment as set
forth in this Section B.4.

           c. Mechanics of Conversion.

              (1) A Record Holder may exercise the conversion option specified
in Section B.4.a. as to all or any part of its Series A Preferred Stock by
surrendering to the Company (or to another person designated by the Company's
Board of Directors) the certificates evidencing the shares such Record Holder
elects to convert, endorsed and assigned to the Company in blank, and
accompanied by written notice confirming such Record Holder's exercise of its
conversion option as to all or a specified portion of the shares evidenced by
the certificates.

              (2) Conversion of shares of Series A Preferred Stock to Common
Stock will be effective when the Record Holder delivers to the Company notice of
its election to convert and duly endorsed certificates evidencing the converted
shares (the "Conversion Date").

              (3) As promptly as practicable after the Conversion Date and in
any event within three (3) days after surrender of the certificate or
certificates representing converted shares of Series A Preferred Stock, the
Company shall issue and deliver at its expense to a converting Record Holder (or
to another person designated in writing by such Record Holder), a certificate
evidencing the number of whole shares of Common Stock to which such Record
Holder is entitled. The person in whose name the certificate or certificates for
Common Stock are to be issued will be deemed the record holder of such Common
Stock as of the close of business on the Conversion Date.

              (4) At the close of business on the Conversion Date, (i) the
converted shares of Series A Preferred Stock will cease to be outstanding, (ii)
the holders of the converted shares will cease to have any further rights with
respect to those shares, except to receive Common Stock and cash (as specified
below) with respect to the converted shares, and (iii) the holders of the
converted shares will be deemed to have become the record holder of the Common
Stock for all purposes.

           d. Fractional Shares. The Record Holder and subsequent Record
Holders, by the acceptance thereof, expressly waive their right to receive
fractional shares of Common Stock or Series A Preferred Stock on conversion of
shares of Series A Preferred Stock. If any fraction of a share would be issuable
on the conversion of Series A Preferred Stock (or any specified portion
thereof), the Company shall pay to the Record Holder in lieu thereof an amount
in cash equal to the product of such resulting fraction and the Conversion
Price.

           e. Reservation of Stock Issuable Upon Conversion. The Company shall
at all times reserve out of its authorized but unissued Common Stock, solely for
the purposes of effecting the conversion of the Series A Preferred Stock, the
number of shares of Common Stock issuable on conversion of all outstanding
Series A Preferred Stock.

           f. Payment of Taxes. The Company shall pay any and all taxes,
documentary or otherwise, that are payable with respect to the issuance or
delivery of Common Stock on

                                       5
<PAGE>

conversion of the Series A Preferred Stock. The Company shall not, however, be
required to pay tax with respect to a transfer involved in the issue or transfer
and delivery of shares of Common Stock in a name other than the record name of
the converted Series A Preferred Stock, and no issuance or delivery shall be
made unless and until the person requesting such issue pays to the Company the
amount of any such tax or establishes to the Company's satisfaction payment of
the tax or that no tax is due. In no event need the Company pay or reimburse a
registered holder for any income tax or ad valorem tax payable by the holder
because of the issuance of Common Stock on conversion of Series A Preferred
Stock.

           g. No Reissuance of Series A Preferred Stock. Shares of Series A
Preferred Stock converted pursuant to this Section B.4. will be held as treasury
shares to be available to make in kind payments pursuant to Section B.1.

           h. Adjustments for Merger, Consolidation, etc. Except as set forth in
Section B.2., in the case of any classification, reclassification, or other
reorganization of the Company's capital stock, or in the case of the merger or
consolidation of the Company with or into another company, or the conveyance to
another company of all or any material portion of the Company's assets, then, as
part of the classification, reclassification, merger, consolidation, or
conveyance, adequate provision shall be made for each Record Holder, on
conversion, to receive on the same basis and conditions set forth in this
Section B.4. with respect to the Common Stock, the stock, securities, or other
property that the Record Holder would have been entitled to receive on such
classification, reclassification, merger, consolidation, or conveyance, if such
Record Holder had converted immediately before the classification,
reclassification, merger, consolidation, or conveyance, and in any such case
appropriate provision will be made with respect to the rights and interests of
such Record Holder to the end that the provisions of this Section B.4. will be
applicable to the shares of stock, securities, or other property deliverable
upon conversion; and, as a condition of any consolidation, merger, or
conveyance, any company that succeeds to the Company by reason of the merger,
consolidation or conveyance shall assume the obligation to deliver, upon
conversion, the shares of stock, securities or other considerations that the
Record Holders are entitled to receive pursuant to this Section B.4.

           i. Subdivision or Combination of Common Stock. If the Company at any
time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the Conversion Price in effect immediately prior to
such subdivision shall be proportionately reduced, and if the Company at any
time combines (by reverse stock split or otherwise) one or more classes of its
outstanding shares of Common Stock into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination shall be
proportionately increased.

           j. No Conversion of Preferred Stock Being Purchased Pursuant to
Redemption. Notwithstanding this Section B.4., no share of Series A Preferred
Stock for which the Record Holder has exercised its optional redemption rights
pursuant to Section B.3. may be converted into Common Stock, unless (i) such
Record Holder effectively withdraws the notice of redemption and nullifies the
redemption or (ii) the requested redemption was not consummated due to
insufficient funds.

                                       6
<PAGE>

        5. VOTING RIGHTS

           a. General. In addition to its voting rights granted by applicable
law, each Record Holder will be entitled to voting rights with respect to all
matters on which holders of Common Stock have the right to vote. Each Record
Holder may cast that number of votes as is equal to the number of whole shares
of Common Stock into which the Record Holder's shares of Series A Preferred
Stock would be convertible pursuant to the applicable provisions set forth above
as of the record date for the determination of stockholders entitled to vote on
the matter. Each Record Holder's votes will be counted together with all other
shares of capital stock having general voting powers and not separately as a
class, except as otherwise provided herein or by applicable law.

           b. Protective Provisions. So long as any shares of the Series A
Preferred Stock are outstanding, the Company shall not, without the affirmative
vote of Record Holders of a majority of the outstanding shares of Series A
Preferred Stock voting together as a separate class, in addition to any other
vote, consent, or approval required by law or otherwise:

              (1) change any of the rights, preferences, or privileges of the
shares of Series A Preferred Stock so as to adversely affect such shares;

              (2) increase or decrease (other than by redemption or conversion)
the authorized shares of Series A Preferred Stock;

              (3) authorize the issuance of any equity security (other than (i)
the issuance of securities upon exercise or conversion of outstanding options or
other convertible securities, (ii) the issuance of stock options to employees,
directors or consultants of the Company, and (iii) the issuance of additional
shares of Series A Preferred Stock pursuant to Section B.1.);

              (4) alter the size of the Company's Board of Directors;

              (5) amend the Company's Certificate of Incorporation, this
Certificate of Designation, or Bylaws in any manner which adversely affects the
relative rights and preferences of the Series A Preferred Stock; or

              (6) enter into any agreement with respect to the foregoing.
