ITEM 14. 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 the current law.

     Article VIII of our amended and restated certificate of incorporation
provides for the indemnification of directors and officers to the fullest extent
permissible under Delaware law.

     Article VI of our bylaws provides for the indemnification of officers,
directors and third parties acting on behalf of Avanex if such person acted in
good faith and in a manner reasonably believed to be in and not opposed to our
best interest, and, with respect to any criminal action or proceeding, the
indemnified party had no reason to believe his or her conduct was unlawful.

     We have entered into indemnification agreements with our directors and
executive officers, in addition to indemnification provided for in our bylaws,
and intend to enter into indemnification agreements with any new directors and
executive officers in the future. The indemnification agreements may require us,
among other things, to indemnify our directors and officers against certain
liability that may arise by reason of their status or service as directors and
officers (other than liabilities arising from willful misconduct of a culpable
nature), to advance their expenses incurred as a result of any proceeding
against them as to which they could be indemnified, and to obtain directors and
officers' insurance, if available on reasonable terms.

     Reference is also made to Section 7 of the form of Underwriting Agreement
contained in Exhibit 1.1 hereto, indemnifying officers and directors of Avanex
against certain liabilities.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     Since inception, we have issued unregistered securities to a limited number
of persons, as described below. None of these transactions involved any
underwriters, underwriting discounts or commissions, or any public offering, and
we believe that each transaction was exempt from the registration requirements
of the Securities Act by virtue of Section 4(2) thereof, Regulation D
promulgated thereunder or Rule 701 pursuant to compensatory benefit plans and
contracts relating to compensation as provided under such Rule 701. The

                                      II-1

recipients of securities in each such transaction represented their intention to
acquire the securities for investment only and not with a view to or for sale in
connection with any distribution thereof, and appropriate legends were affixed
to the share certificates and instruments issued in such transactions. All
recipients had adequate access, through their relationships with us, to

          directors pursuant to our 1998 Stock Plan, as amended.

      (2) From inception through October 1, 1999, we issued an aggregate of

          our common stock at an exercise price of $6.00 a share to each of
          Simon Cao, Haiguang Lu, and Lee Wang.

      (8) On February 19, 1999 and March 25, 1999, we sold 9,032,169 shares of
          Series C Preferred Stock for $0.756 per share to a group of private
          investors for an aggregate purchase price of $6,828,320.

      (9) On July 8, 1999, in connection with a Revolving Credit and Security
          Agreement, we issued a warrant to purchase 19,565 shares of Series D
          Preferred Stock at an exercise price of $5.75 to Comerica
          Bank -- California.

     Schedules not listed above have been omitted because they are not
applicable or are not required or the information required to be set forth
therein is included in the consolidated financial statements or notes thereto.


ITEM 17. UNDERTAKINGS

     We hereby undertake to provide to the Underwriters at the closing specified
in the Underwriting Agreement certificates in such denominations and registered
in such names as required by the Underwriters to permit prompt delivery to each
purchaser.

     Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement or otherwise, the Registrant 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 the Registrant in the
successful defense of any action, suit or proceeding) is asserted by director,
officer or controlling person in connection with the securities being registered
hereunder, the Registrant 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.

     We hereby undertake that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of Prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of Prospectus 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.

                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               AVANEX CORPORATION

                             Void after 12/31, 2003


     This certifies that, for value received, HAIGUANG LU or his or her
registered assigns ("Holder") is entitled, subject to the terms set forth
below, to purchase from AVANEX CORPORATION (the "Company"), a California
corporation, Seventy-Five Thousand (75,000) shares of the Common Stock of the
Company, as constituted on the date hereof (the "Warrant Issue Date"), upon
surrender hereof, at the principal office of the Company referred to below, with
the subscription form attached hereto duly executed, and simultaneous payment
therefor in lawful money of the United States or otherwise as hereinafter
provided, at the Exercise Price as set forth in Section 2 below. The number,
character and Exercise Price of such shares of Common Stock are subject to
adjustment as provided below.

     1.   Term of Warrant. Subject to the terms and conditions set forth
herein, this Warrant shall be exercisable, in whole or in part, during the term
commencing on the Warrant Issue Date and ending at 5:00 p.m., Pacific Standard
Time, on 12/31, 2003 (the "Term"), and shall be void thereafter.

     2.   Exercise Price. The Exercise Price at which this Warrant may be
exercised shall be $6.00 per share of Common Stock as adjusted from time to time
pursuant to Section 10 hereof (the "Exercise Price").

     3.   Exercise of Warrant.

          (a)  Manner of Exercise. This Warrant is exercisable by the Holder in
whole or in part, but not for less than twenty thousand (20,000) shares at a
time (or if the maximum number of shares purchasable upon exercise of this
Warrant is less than 20,000, this Warrant shall be exercisable for such lesser
number of shares which may then constitute the maximum number purchasable), at
any time, or from time to time, during the term hereof as described in Section
1 above, by the surrender of this



<PAGE>   3
Warrant and the Notice of Exercise annexed hereto duly completed and executed
on behalf of the Holder, at the office of the Company (or such other office or
agency of the Company as it may designated by notice in writing to the Holder
at the address of the Holder appearing on the books of the Company). Unless
Holder is exercising the conversion right set forth in Section 3(c), Holder
shall also deliver to the Company a check for the aggregate Exercise Price for
the shares of Common Stock being purchased.

          (b)  This Warrant shall be deemed to have been exercised immediately
prior to the close of business on the date of its surrender for exercise as
provided above, and the person entitled to receive the shares of Common Stock
issuable upon such exercise shall be treated for all purposes as the holder of
record of such shares as of the close of business on such date. As promptly as
practicable on or after such date and in any event within twenty (20) days
thereafter, the Company at its expense shall issue and deliver to the person or
persons entitled to receive the same a certificate or certificates for the
number of shares issuable upon such exercise. In the event that this Warrant is
exercised in part, the Company at its expense will execute and deliver a new
Warrant of like tenor exercisable for the remaining number of shares for which
this Warrant may then be exercised.

          (c)  Net Exercise Conversion Right. In lieu of exercising this
Warrant as specified in Section 3(a), Holder may from time to time convert this
Warrant, in whole or in part, into a number of Shares determined by dividing
(y) the aggregate fair market value of the shares of Common Stock or other
securities otherwise issuable upon exercise of this Warrant minus the aggregate
Warrant Price of such shares of Common Stock by (z) the fair market value of
one shares of Common Stock. The fair market value of the shares of Common Stock
shall be determined pursuant to Section 3(d).

          (d)  Fair Market Value. The Board of Directors of the Company shall
determine fair market value of the Company's Common Stock in its reasonable
good faith judgment. The foregoing notwithstanding, if Holder advises the Board
of Directors in writing that Holder disagrees with such determination, then the
Company and Holder shall promptly agree upon a reputable investment banking
firm to undertake such valuation. If the valuation of such investment banking
firm is greater than that determined by the Board of Directors, then all fees
and expenses of such investment banking firm shall be paid by the Company. In
all other circumstances, such fees and expenses shall be paid by Holder.

     4.   No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional share shall be issued upon the exercise of this
Warrant. In lieu of any fractional share to which the Holder would otherwise be
entitled, the Company shall make a cash payment equal to the Exercise Price
multiplied by such fraction.

     5.   Replacement of Warrant. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of loss, theft, or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and substance to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense shall execute and deliver, in lieu of this
Warrant, a new warrant of like tenor and amount.


                                      -2-

     6.   Rights of Stockholders. Subject to Sections 8 and 10 of this Warrant,
the Holder shall not be entitled to vote or receive dividends or be deemed the
holder of Common Stock or any other securities of the Company that may at any
time be issuable on the exercise hereof for any purpose, nor shall anything
contained herein be construed to confer upon the Holder, as such, any of the
rights of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, or change of stock to no par value, consolidation, merger, conveyance or
otherwise) or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until the Warrant shall have been exercised and
the shares of Common Stock purchasable upon the exercise hereof (the "Warrant
Shares") shall have been issued, as provided herein.

     7.   Compliance with Securities Laws. This Warrant may not be transferred
or assigned in whole or in part without compliance with all applicable federal
and state securities laws by the transferor and the transferee (including the
delivery of investment representation letters and legal opinions reasonably
satisfactory to the Company, if such are requested by the Company).

          (a)  The Holder of this Warrant, by acceptance thereof, acknowledges
that this Warrant and the shares of Common Stock to be issued upon exercise
hereof are being acquired solely for the Holder's own account and not as a
nominee for any other party, and for investment, and that the Holder will not
offer, sell or otherwise dispose of this Warrant or any shares of Common Stock
to be issued upon exercise hereof except under circumstances that will not
result in a violation of any federal securities laws, including without
limitation the Securities Act of 1933, as amended (the "Act"), any state
securities laws or any applicable securities law of foreign jurisdictions, or
any rules or regulations promulgated thereunder. Upon exercise of this Warrant,
the Holder shall, if requested by the Company, confirm in writing in a form
satisfactory to the Company, that the shares of Common Stock so purchased are
being acquired solely for the Holder's own account and not as a nominee for any
other party, for investment, and not with a view toward distribution or resale.

          (b)  Without in any way limiting the representations set forth in (a)
above, the Holder further agrees not to make any disposition of all or any
portion of this Warrant or any Warrant Shares unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by this
Section 7, and the satisfaction of the following conditions: (i) the Holder
shall have notified the Company of the proposed disposition and shall have
furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, and (ii) if reasonably requested by the
Company, the Holder shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the Company, that such disposition will not
require registration of such securities under the Act.

          (c)  This Warrant and all shares issuable hereunder shall bear the
following legends:

               (i)  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED


                                      -3-
<PAGE>   5
IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO SUCH
SECURITIES, OR DELIVERY OF AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
SATISFACTORY TO THE ISSUER OF THESE SECURITIES THAT SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE WITH THE ACT."

               (ii) Any legend required by applicable state law.

     8.   Reservation of Stock. The Company covenants that during the Term this
Warrant is exercisable, the Company will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of Common Stock upon the exercise of this Warrant and, from time to time, will
take all steps necessary to provide sufficient reserves of shares of the Common
Stock issuable upon the exercise of the Warrant. The Company further covenants
that all shares that may be issued upon the exercise of rights represented by
this Warrant and payment of the Exercise Price, all as set forth herein, will be
free from all taxes, liens, and charges in respect to the issue thereof (other
than taxes in respect to any transfer occurring contemporaneously or otherwise
specified herein). The Company agrees that its issuance of this Warrant shall
constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates for
shares of Common Stock upon the exercise of this Warrant.

     9.   Amendments and Waivers. Any term of this Warrant may be amended and
the observance of any term of this Warrant may be waived (either generally or in
a particular instance and either retroactively or prospectively) only with the
written consent of the Company and the Holder. No waivers of or exceptions to
any term, condition or provision of this Warrant, in any one or more instances,
shall be deemed to be, or construed as, a further or continuing waiver of any
such term, condition or provision.

     10.   Adjustments. The Exercise Price and the number of shares purchasable
hereunder are subject to adjustment from time to time as follows:

          (a)  Reclassification, etc. If the Company at any time while this
Warrant, or any portion thereof, remains outstanding and unexpired shall, by
reclassification of securities or otherwise, change any of the securities as to
which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, this Warrant shall
thereafter represent the right to acquire such number and kind of securities as
would have been issuable as the result of such change with respect to the
securities which were subject to the purchase rights under the Warrant
immediately prior to such reclassification or other change and the Exercise
Price therefor shall be appropriately adjusted, all subject to further
adjustment as provided in this Section 10.

          (b)  Split, Subdivision or Combination of Shares. If the Company at
any time while this Warrant, or any portion hereof, remains outstanding and
unexpired shall split, subdivide or combine the securities as to which purchase
rights under this Warrant exist, into a different number of securities of the
same class, the Exercise Price for such securities shall be proportionately
decreased and the number of securities issuable upon exercise proportionately
increased in the case of a split or subdivision

                                      -4-

<PAGE>   6
or the Exercise Price of such securities shall be proportionately increased and
the number of securities issuable upon exercise proportionately decreased in the
case of a combination.

          (c)  Adjustments for Dividends in Stock or Other Securities or
Property. If, while this Warrant, or any portion hereof, remains outstanding and
unexpired the holders of the securities as to which purchase rights under this
Warrant exist at the time shall have received, or, on or after the record date
fixed for the determination of eligible Stockholders, shall have become entitled
to receive, without payment therefor, other or additional stock or other
securities or property (other than cash) of the Company by way of dividend, then
and in each case, this Warrant shall represent the right to acquire, in addition
to the number of shares of the security receivable upon the exercise of this
Warrant, and without payment of any additional consideration thereof, the amount
of such other or additional stock or other securities or property (other than
cash) of the Company which such holder would hold on the date of such exercise
had it been the holder of record of the security receivable upon exercise of
this Warrant on the date hereof and had thereafter, during the period from the
date hereof to and including the date of such exercise, retained such shares
and/or all other additional stock available by it as aforesaid during such
period, giving effect to all adjustments called for during such period by the
provisions of this Section 10.

          (d)  Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment pursuant to this Section 10, the Company shall, upon
the written request of any holder of this Warrant, furnish or cause to be
furnished to such holder a certificate setting forth: (i) such adjustments and
readjustments; (ii) the Exercise Price at the time in effect; and (iii) the
number of shares and the amount, if any, of other property which at the time
would be received upon the exercise of the Warrant.

          (e)  No Impairment. The Company will not, by any voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Company, but will at all times in good
faith assist in the carrying out of all of the provisions of this Section 10 and
in the taking of all such action as may be necessary or appropriate in order to
protect the rights of the holders of this Warrant against impairment.

    11.   Expiration of Warrant Upon Occurrence of Certain Events.

          (a)  Upon the closing of any Acquisition or Initial Public Offering,
this Warrant shall expire.

          (b)  Definitions. For the purpose of this Section 11 the following
definitions shall apply:

               (i)  "Acquisition" means any sale, license, or other disposition
of all or substantially all of the assets (including intellectual property) of

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT

                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               AVANEX CORPORATION

                           Void after Dec. 31st, 2003


     This certifies that, for value received, SIMIN CAI or his or her
registered assigns ("Holder") is entitled, subject to the terms set forth
below, to purchase from AVANEX CORPORATION (the "Company"), a California
corporation, Seventy-Five Thousand (75,000) shares of the Common Stock of the
Company, as constituted on the date hereof (the "Warrant Issue Date"), upon
surrender hereof, at the principal office of the Company referred to below, with
the subscription form attached hereto duly executed, and simultaneous payment
therefor in lawful money of the United States or otherwise as hereinafter
provided, at the Exercise Price as set forth in Section 2 below. The number,
character and Exercise Price of such shares of Common Stock are subject to
adjustment as provided below.

     1.   Term of Warrant. Subject to the terms and conditions set forth
herein, this Warrant shall be exercisable, in whole or in part, during the term
commencing on the Warrant Issue Date and ending at 5:00 p.m., Pacific Standard
Time, on Dec. 31st, 2003 (the "Term"), and shall be void thereafter.

     2.   Exercise Price. The Exercise Price at which this Warrant may be
exercised shall be $6.00 per share of Common Stock as adjusted from time to time
pursuant to Section 10 hereof (the "Exercise Price").

     3.   Exercise of Warrant.

          (a)  Manner of Exercise. This Warrant is exercisable by the Holder in
whole or in part, but not for less than twenty thousand (20,000) shares at a
time (or if the maximum number of shares purchasable upon exercise of this
Warrant is less than 20,000, this Warrant shall be exercisable for such lesser
number of shares which may then constitute the maximum number purchasable), at
anytime, or from time to time, during the term hereof as described in Section
1 above, by the surrender of this



<PAGE>   12
Warrant and the Notice of Exercise annexed hereto duly completed and executed on
behalf of the Holder, at the office of the Company (or such other office or
agency of the Company as it may designate by notice in writing to the Holder at
the address of the Holder appearing on the books of the Company). Unless Holder
is exercising the conversion right set forth in Section 3(c), Holder shall also
deliver to the Company a check for the aggregate Exercise Price for the shares
of Common Stock being purchased.

          (b)  This Warrant shall be deemed to have been exercised immediately
prior to the close of business on the date of its surrender for exercise as
provided above, and the person entitled to receive the share of Common Stock
issuable upon such exercise shall be treated for all purposes as the holder of
record of such shares as of the close of business on such date. As promptly as
practicable on or after such date and in any event within twenty (20) days
thereafter, the Company at its expense shall issue and deliver to the person or
persons entitled to receive the same a certificate or certificates for the
number of shares issuable upon such exercise. In the event this Warrant is
exercised in part, the Company at its expense will execute and deliver a new
Warrant of like tenor exercisable for the remaining number of shares for which
this Warrant may then be exercised.

          (c)  Net Exercise Conversion Right. In lieu of exercising this Warrant
as specified in Section 3(a), Holder may from time to time convert this Warrant,
in whole or in part, into a number of Shares determined by dividing (y) the
aggregate fair market value of the shares of Common Stock or other securities
otherwise issuable upon exercise of this Warrant minus the aggregate Warrant
Price of such shares of Common Stock by (z) the fair market value of one shares
of Common Stock. The fair market value of the shares of Common Stock shall be
determined pursuant to Section 3(d).

          (d)  Fair Market value. The Board of Directors of the Company shall
determine fair market value of the Company's Common Stock in its reasonable good
faith judgment. The foregoing notwithstanding, if Holder advises the Board of
Directors in writing that Holder disagrees with such determination, then the
Company and Holder shall promptly agree upon a reputable investment banking firm
to undertake such valuation. If the valuation of such investment banking firm is
greater than that determined by the Board of Directors, then all fees and
expenses of such investment banking firm shall be paid by the Company. In all
other circumstances, such fees and expenses shall be paid by Holder.

     4.   No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional share shall be issued upon the exercise of this Warrant.
In lieu of any fractional share to which the Holder would otherwise be entitled,
the Company shall make a cash payment equal to the Exercise Price multiplied by
such fraction.

     5.   Replacement of Warrant. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction, or mutilation of this Warrant
and, in the case of loss, theft, or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and substance to the Company or, in
the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new
warrant of like tenor and amount.

                                      -2-

<PAGE>   13
     6.  Rights of Stockholders. Subject to Sections 8 and 10 of this Warrant,
the Holder shall not be entitled to vote or receive dividends or be deemed the
holder of Common Stock or any other securities of the Company that may at any
time be issuable on the exercise hereof for any purpose, nor shall anything
contained herein be construed to confer upon the Holder, as such, any of the
rights of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, or change of stock to no par value, consolidation, merger, conveyance,
or otherwise) or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until the Warrant shall have been exercised
and the shares of Common Stock purchasable upon the exercise hereof (the
"Warrant Shares") shall have been issued, as provided herein.

     7.  Compliance with Securities Laws. This Warrant may not be transferred
or assigned in whole or in part without compliance with all applicable federal
and state securities laws by the transferor and the transferee (including the
delivery of investment representation letters and legal opinions reasonably
satisfactory to the Company, if such are requested by the Company).

         (a)  The Holder of this Warrant, by acceptance thereof, acknowledges
that this Warrant and the shares of Common Stock to be issued upon exercise
hereof are being acquired solely for the Holder's own account and not as a
nominee for any other party, and for investment, and that the Holder will not
offer, sell or otherwise dispose of this Warrant or any shares of Common Stock
to be issued upon exercise hereof except under circumstances that will not
result in a violation of any federal securities laws, including without
limitation the Securities Act of 1933, as amended (the "Act"), any state
securities laws or any applicable securities law of foreign jurisdictions, or
any rules or regulations promulgated thereunder. Upon exercise of this Warrant,
the Holder shall, if requested by the Company, confirm in writing in a form
satisfactory to the Company, that the shares of Common Stock so purchased are
being acquired solely for the Holder's own account and not as a nominee for any
other party, for investment, and not with a view toward distribution or resale.

         (b)  Without in any way limiting the representations set forth in (a)
above, the Holder further agrees not to make any disposition of all or any
portion of this Warrant or any Warrant Shares unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by this
Section 7, and the satisfaction of the following conditions: (i) the Holder
shall have notified the Company of the proposed disposition and shall have
furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, and (ii) if reasonably requested by the
Company, the Holder shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the Company, that such disposition will not
require registration of such securities under the Act.

         (c)  This Warrant and all shares issuable hereunder shall bear the
following legends:

              (i)  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED

                                      -3-
<PAGE>   14
IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO SUCH
SECURITIES, OR DELIVERY OF AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
SATISFACTORY TO THE ISSUER OF THESE SECURITIES THAT SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE WITH THE ACT."

               (ii)  Any legend required by applicable state law.

     8.  Reservation of Stock. The Company covenants that during the Term this
Warrant is exercisable, the Company will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of Common Stock upon the exercise of this Warrant and, from time to time, will
take all steps necessary to provide sufficient reserves of shares of the Common
Stock issuable upon the exercise of the Warrant. The Company further covenants
that all shares that may be issued upon the exercise of rights represented by
this Warrant and payment of the Exercise Price, all as set forth herein, will
be free from all taxes, liens, and charges in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously or
otherwise specified herein). The Company agrees that its issuance of this
Warrant shall constitute full authority to its officers who are charged with
the duty of executing stock certificates to execute and issue the necessary
certificates for shares of Common Stock upon the exercise of this Warrant.

     9.  Amendments and Waivers. Any term of this Warrant may be amended and the
observance of any term of this Warrant may be waived (either generally or in a
particular instance and either retroactively or prospectively) only with the
written consent of the Company and the Holder. No waivers of or exceptions to
any term, condition or provision of this Warrant, in any one or more instances,
shall be deemed to be, or construed as, a further or continuing waiver of any
such term, condition or provision.

     10. Adjustments. The Exercise Price and the number of shares purchasable
hereunder are subject to adjustment from time to time as follows:

         (a)  Reclassification, etc. If the Company at any time while this
Warrant, or any portion thereof, remains outstanding and unexpired shall, by
reclassification of securities or otherwise, change any of the securities as to
which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, this Warrant shall
thereafter represent the right to acquire such number and kind of securities as
would have been issuable as the result of such change with respect to the
securities which were subject to the purchase rights under this Warrant
immediately prior to such reclassification or other change and the Exercise
Price therefor shall be appropriately adjusted, all subject to further
adjustment as provided in this Section 10.

         (b)  Split Subdivision or Combination of Shares.  If the Company at any
time while this Warrant, or any portion hereof, remains outstanding and
unexpired shall split, subdivide or combine the securities as to which purchase
rights under this Warrant exist, into a different number of securities of the
same class, the Exercise Price for such securities shall be proportionately
decreased and the number of securities issuable upon exercise proportionately
increased in the case of a split or subdivision

                                      -4-
<PAGE>   15
or the Exercise Price of such securities shall be proportionately increased and
the number of securities issuable upon exercise proportionately decreased in
the case of a combination.

          (c)  Adjustments for Dividends in Stock or Other Securities or
Property. If, while this Warrant, or any portion hereof, remains outstanding
and unexpired the holders of the securities as to which purchase rights under
this Warrant exist at the time shall have received, or, on or after the record
date fixed for the determination of eligible Stockholders, shall have become
entitled to receive, without payment therefor, other or additional stock or
other securities or property (other than cash) of the Company by way of
dividend, then and in each case, this Warrant shall represent the right to
acquire, in addition to the number of shares of the security receivable upon
the exercise of this Warrant, and without payment of any additional
consideration thereof, the amount of such other or additional stock or other
securities or property (other than cash) of the Company which such holder would
hold on the date of such exercise had it been the holder of record of the
security receivable upon exercise of this Warrant on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock available
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by the provisions of this Section 10.

          (d)  Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment pursuant to this Section 10, the Company shall, upon
the written request of any holder of this Warrant, furnish or cause to be
furnished to such holder a certificate setting forth: (i) such adjustments and
readjustments; (ii) the Exercise Price at the time in effect; and (iii) the
number of shares and the amount, if any, of other property which at the time
would be received upon the exercise of the Warrant.

          (e)  No Impairment. The Company will not, by any voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Company, but will at all times in good
faith assist in the carrying out of all of the provisions of this Section 10
and in the taking of all such action as may be necessary or appropriate in
order to protect the rights of the holders of this Warrant against impairment.

     11.  Expiration of Warrant Upon Occurrence of Certain Events.

          (a)  Upon the closing of any Acquisition or Initial Public Offering,
this Warrant shall expire.

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT
IN EFFECT WITH RESPECT TO SUCH SECURITIES, OR DELIVERY OF AN OPINION OF COUNSEL
IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES THAT SUCH

                                                        Warrant to Purchase

                                                        of Common Stock
                                                        Dated 12/31, 1998

                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               AVANEX CORPORATION

                             Void after 12/31, 2003


     This certifies that, for value received, LEE WANG or his or her registered
assigns ("Holder") is entitled, subject to the terms set forth below, to
purchase from AVANEX CORPORATION (the "Company"), a California corporation,
Seventy-Five Thousand (75,000) shares of the Common Stock of the Company, as
constituted on the date hereof (the "Warrant Issue Date"), upon surrender
hereof, at the principal office of the Company referred to below, with the
subscription form attached hereto duly executed, and simultaneous payment
therefor in lawful money of the United States or otherwise as hereinafter
provided, at the Exercise Price as set forth in Section 2 below. The number,
character and Exercise Price of such shares of Common Stock are subject to
adjustment as provided below.

     1.   Term of Warrant. Subject to the terms and conditions set forth
herein, this Warrant shall be exercisable, in whole or in part, during the term
commencing on the Warrant Issue Date and ending at 5:00 p.m., Pacific Standard
Time, on 12/31, 2003 (the "Term"), and shall be void thereafter.

     2.   Exercise Price. The Exercise Price at which this Warrant may be
exercised shall be $6.00 per share of Common Stock as adjusted from time to time
pursuant to Section 10 hereof (the "Exercise Price").

     3.   Exercise of Warrant.

          (a)  Manner of Exercise. This Warrant is exercisable by the Holder in
whole or in part, but not for less than twenty thousand (20,000) shares at a
time (or if the maximum number of shares purchasable upon exercise of this
Warrant is less than 20,000, this Warrant shall be exercisable for such lesser
number of shares which may then constitute the maximum number purchasable), at
any time, or from time to time, during the term hereof as described in Section
1 above, by the surrender of this



<PAGE>   20
Warrant and the Notice of Exercise annexed hereto duly completed and executed on
behalf of the Holder, at the office of the Company (or such other office or
agency of the Company as it may designate by notice in writing to the Holder at
the address of the Holder appearing on the books of the Company). Unless Holder
is exercising the conversion right set forth in Section 3(c), Holder shall also
deliver to the Company a check for the aggregate Exercise Price for the shares
of Common Stock being purchased.

          (b)  This Warrant shall be deemed to have been exercised immediately
prior to the close of business on the date of its surrender for exercise as
provided above, and the person entitled to receive the shares of Common Stock
issuable upon such exercise shall be treated for all purposes as the holder of
record of such shares as of the close of business on such date. As promptly as
practicable on or after such date and in any event within twenty (20) days
thereafter, the Company at its expense shall issue and deliver to the person or
persons entitled to receive the same a certificate or certificates for the
number of shares issuable upon such exercise. In the event that this Warrant is
exercised in part, the Company at its expense will execute and deliver a new
Warrant of like tenor exercisable for the remaining number of shares for which
this Warrant may then be exercised.

          (c)  Net Exercise Conversion Right. In lieu of exercising this Warrant
as specified in Section 3(a), Holder may from time to time convert this Warrant,
in whole or in part, into a number of Shares determined by dividing (y) the
aggregate fair market value of the shares of Common Stock or other securities
otherwise issuable upon exercise of this Warrant minus the aggregate Warrant
Price of such shares of Common Stock by (z) the fair market value of one shares
of Common Stock. The fair market value of the shares of Common Stock shall be
determined pursuant to Section 3(d).

          (d)  Fair Market Value. The Board of Directors of the Company shall
determine fair market value of the Company's Common Stock in its reasonable good
faith judgment. The foregoing notwithstanding, if Holder advises the Board of
Directors in writing that Holder disagrees with such determination, then the
Company and Holder shall promptly agree upon a reputable investment banking firm
to undertake such valuation. If the valuation of such investment banking firm is
greater than that determined by the Board of Directors, then all fees and
expenses of such investment banking firm shall be paid by the Company. In all
other circumstances, such fees and expenses shall be paid by Holder.

     4.   No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional share shall be issued upon the exercise of this Warrant.
In lieu of any fractional share to which the Holder would otherwise be entitled,
the Company shall make a cash payment equal to the Exercise Price multiplied by
such fraction.

     5.   Replacement of Warrant. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction, or mutilation of this Warrant
and, in the case of loss, theft, or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and substance to the Company or, in
the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new
warrant of like tenor and amount.

                                      -2-

<PAGE>   21
     6.   Rights of Stockholders. Subject to Sections 8 and 10 of this Warrant,
the Holder shall not be entitled to vote or receive dividends or be deemed the
holder of Common Stock of any other securities of the Company that may at any
time be issuable on the exercise hereof for any purpose, nor shall anything
contained herein be construed to confer upon the Holder, as such, any of the
rights of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, or change of stock to no par value, consolidation, merger, conveyance,
or otherwise) or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until the Warrant shall have been exercised
and the shares of Common Stock purchasable upon the exercise hereof (the
"Warrant Shares") shall have been issued, as provided herein.

     7.   Compliance with Securities Laws. This Warrant may not be transferred
or assigned in whole or in part without compliance with all applicable federal
and state securities laws by the transferor and the transferee (including the
delivery of investment representation letters and legal opinions reasonably
satisfactory to the Company, if such are requested by the Company).

          (a)  The Holder of this Warrant, by acceptance thereof, acknowledges
that this Warrant and the shares of Common Stock to be issued upon exercise
hereof are being acquired solely for the Holder's own account and not as a
nominee for any other party, and for investment, and that the Holder will not
offer, sell or otherwise dispose of this Warrant or any shares of Common Stock
to be issued upon exercise hereof except under circumstances that will not
result in a violation of any federal securities laws, including without
limitation the Securities Act of 1933, as amended (the "Act"), any state
securities laws or any applicable securities law of foreign jurisdictions, or
any rules or regulations promulgated thereunder. Upon exercise of this Warrant,
the Holder shall, if requested by the Company, confirm in writing in a form
satisfactory to the Company, that the shares of Common Stock so purchased are
being acquired solely for the Holder's own account and not as a nominee for any
other party, for investment, and not with a view toward distribution or resale.

          (b)  Without in any way limiting the representations set forth in (a)
above, the Holder further agrees not to make any disposition of all or any
portion of this Warrant or any Warrant Shares unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by this
Section 7, and the satisfaction of the following conditions: (i) the Holder
shall have notified the Company of the proposed disposition and shall have
furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, and (ii) if reasonably requested by the
Company, the Holder shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the Company, that such disposition shall
not require registration of such securities under the Act.

          (c)  This Warrant and all shares issuable hereunder shall bear the
following legends:

               (i)  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED


                                      -3-
<PAGE>   22
IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO SUCH
SECURITIES, OR DELIVERY OF AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
SATISFACTORY TO THE ISSUER OF THESE SECURITIES THAT SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE WITH THE ACT."

               (ii) Any legend required by applicable state law.

     8.   Reservation of Stock. The Company covenants that during the Term this
Warrant is exercisable, the Company will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of Common Stock upon the exercise of this Warrant and, from time to time, will
take all steps necessary to provide sufficient reserves of shares of the Common
Stock issuable upon the exercise of the Warrant. The Company further covenants
that all shares that may be issued upon the exercise of rights represented by
this Warrant and payment of the Exercise Price, all as set forth herein, will
be free from all taxes, liens, and charges in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously or
otherwise specified herein). The Company agrees that its issuance of this
Warrant shall constitute full authority to its officers who are charged with
the duty of executing stock certificates to execute and issue the necessary
certificates for shares of Common Stock upon the exercise of this Warrant.

     9.   Amendments and Waivers. Any term of this Warrant may be amended and
the observance of any term of this Warrant may be waived (either generally or
in a particular instance and either retroactively or prospectively) only with
the written consent of the Company and the Holder. No waivers of or exceptions
to any term, condition or provision of this Warrant, in any one or more
instances, shall be deemed to be, or construed as, a further or continuing
waiver of any such term, condition or provision.

     10.  Adjustments. The Exercise Price and the number of shares purchasable
hereunder are subject to adjustment from time to time as follows:

          (a)  Reclassification, etc. If the Company at any time while this
Warrant, or any portion thereof, remains outstanding and unexpired shall, by
reclassification of securities or otherwise, change any of the securities as to
which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, this Warrant shall
thereafter represent the right to acquire such number and kind of securities as
would have been issuable as the result of such change with respect to the
securities which were subject to the purchase rights under this Warrant
immediately prior to such reclassification or other change and the Exercise
Price therefor shall be appropriately adjusted, all subject to further
adjustment as provided in this Section 10.

          (b)  Split, Subdivision or Combination of Shares. If the Company at
any time while this Warrant, or any portion hereof, remains outstanding and
unexpired shall split, subdivide or combine the securities as to which purchase
rights under this Warrant exist, into a different number of securities of the
same class, the Exercise Price for such securities shall be proportionately
decreased and the number of securities issuable upon exercise proportionately
increased in the case of a split or subdivision


                                      -4-
<PAGE>   23
or the Exercise Price of such securities shall be proportionately increased and
the number of securities issuable upon exercise proportionately decreased in the
case of a combination.

          (c)  Adjustments for Dividends in Stock or Other Securities or
Property. If, while this Warrant, or any portion hereof, remains outstanding and
unexpired the holders of the securities as to which purchase rights under this
Warrant exist at the time shall have received, or, on or after the record date
fixed for the determination of eligible Stockholders, shall have become entitled
to receive, without payment therefor, other or additional stock or other
securities or property (other than cash) of the Company by way of dividend, then
and in each case, this Warrant shall represent the right to acquire, in addition
to the number of shares of the security receivable upon the exercise of this
Warrant, and without payment of any additional consideration thereof, the amount
of such other or additional stock or other securities or property (other than
cash) of the Company which such holder would hold on the date of such exercise
had it been the holder of record of the security receivable upon exercise of
this Warrant on the date hereof and had thereafter, during the period from the
date hereof to and including the date of such exercise, retained such shares
and/or all other additional stock available by it as aforesaid during such
period, giving effect to all adjustments called for during such period by the
provisions of this Section 10.

          (d)  Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment pursuant to this Section 10, the Company shall, upon
the written request of any holder of this Warrant, furnish or cause to be
furnished to such holder a certificate setting forth: (i) such adjustments and
readjustments; (ii) the Exercise Price at the time in effect; and (iii) the
number of shares and the amount, if any, of other property which at the time
would be received upon the exercise of the Warrant.

          (e) No Impairment. The Company will not, by any voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Company, but will at all times in good
faith assist in the carrying out of all of the provisions of this Section 10 and
in the taking of all such action as may be necessary or appropriate in order to
protect the rights of the holders of this Warrant against impairment.

     11.  Expiration of Warrant Upon Occurrence of Certain Events.

          (a)  Upon the closing of any Acquisition or Initial Public Offering,
this Warrant shall expire.

of all or substantially all of the assets (including intellectual property) of

surviving entity after the transaction.

shall inure to the benefit of and be binding upon the Company and Holder and
their respective permitted successors and assigns.

     13.  Attorneys' Fees. If any action of law or equity is necessary to
enforce or interpret the terms of this Warrant, the prevailing party shall be

      1. Purposes of the Plan. The purposes of this 1998 Stock Plan are:

                  positions of substantial responsibility,

            -     to provide additional incentive to Employees, Directors and
                  Consultants, and

            -     to promote the success of the Company's business.

            Options granted under the Plan may be Incentive Stock Options or
Nonstatutory Stock Options, as determined by the Administrator at the time of

returned to the Plan and shall not become available for future distribution
under the Plan, except that if Shares of Restricted Stock are repurchased by the
Company at their original purchase price, such Shares shall become available for
future grant under the Plan.

      4. Administration of the Plan.

            (a)   Procedure.

                     (i) Multiple Administrative Bodies. Different Committees
with respect to different groups of Service Providers may administer the Plan.

                     (ii) Section 162(m). To the extent that the Administrator
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

                     (iii) Rule 16b-3. To the extent desirable to qualify
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.

                     (iv) Other Administration. Other than as provided above,
the Plan shall be administered by (A) the Board or (B) a Committee, which
committee shall be constituted to satisfy Applicable Laws.

            (b) Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                     (i) to determine the Fair Market Value;

                     (ii) to select the Service Providers to whom Options and
Stock Purchase Rights may be granted hereunder;



                                      -4-
<PAGE>   5
                     (iii) to determine the number of shares of Common Stock to
be covered by each Option and Stock Purchase Right granted hereunder;

                     (iv) to approve forms of agreement for use under the Plan;

                     (v) to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any Option or Stock Purchase Right granted
hereunder. Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options or Stock Purchase Rights may be
exercised (which may be based on performance criteria), any vesting acceleration
or waiver of forfeiture restrictions, and any restriction or limitation
regarding any Option or Stock Purchase Right or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                     (vi) to reduce the exercise price of any Option or Stock
Purchase Right to the then current Fair Market Value if the Fair Market Value of
the Common Stock covered by such Option or Stock Purchase Right shall have
declined since the date the Option or Stock Purchase Right was granted;

                     (vii) to institute an Option Exchange Program;

                     (viii) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                     (ix) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

                     (x) to modify or amend each Option or Stock Purchase Right
(subject to Section 15(c) of the Plan), including the discretionary authority to
extend the post-termination exercisability period of Options longer than is
otherwise provided for in the Plan;

                     (xi) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

                     (xii) to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

                     (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

            (c) Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

      5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may
be granted to Service Providers. Incentive Stock Options may be granted only to
Employees.

      6. Limitations.

            (a) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

            (b) Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

            (c) The following limitations shall apply to grants of Options:

                     (i) No Service Provider shall be granted, in any fiscal
year of the Company, Options to purchase more than 1,000,000 Shares.

                     (ii) In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional
3,000,000 Shares, which shall not count against the limit set forth in
subsection (i) above.

                     (iii) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 13.

                     (iv) If an Option is cancelled in the same fiscal year of
the Company in which it was granted (other than in connection with a transaction
described in Section 13), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

      7. Term of Plan. Subject to Section 19 of the Plan, the amendment and
restatement of the Plan shall become effective upon the IPO Effective Date. It
shall continue in effect for a term of ten (10) years from the date of obtaining
stockholder approval of the Plan in December, 1999, unless terminated earlier
under Section 15 of the Plan.



                                      -6-
<PAGE>   7
      8. Term of Option. The term of each Option shall be stated in the Option
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement.

      9. Option Exercise Price and Consideration.

            (a) Exercise Price. The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                     (i) In the case of an Incentive Stock Option

                        (A) granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                        (B) granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

                     (ii) In the case of a Nonstatutory Stock Option, the per
Share exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                     (iii) Notwithstanding the foregoing, Options may be granted
with a per Share exercise price of less than 100% of the Fair Market Value per
Share on the date of grant pursuant to a merger or other corporate transaction.

            (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

            (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

                     (i) cash;

                     (ii) check;



                                      -7-
<PAGE>   8
                     (iii) promissory note;

                     (iv) other Shares which (A) in the case of Shares acquired
upon exercise of an option, have been owned by the Optionee for more than six
months on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

                     (v) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

                     (vi) a reduction in the amount of any Company liability to
the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                     (vii) any combination of the foregoing methods of payment;
or

                     (viii) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws.

      10. Exercise of Option.

            (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

                  Exercising an Option in any manner shall decrease the number
of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

            (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise



                                      -8-
<PAGE>   9
his or her Option within such period of time as is specified in the Option
Agreement to the extent that the Option is vested on the date of termination
(but in no event later than the expiration of the term of such Option as set
forth in the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for three (3) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified by the
Administrator, the Option shall terminate, and the Shares covered by such Option
shall revert to the Plan.

            (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

            (d) Death of Optionee. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death. In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination. If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan. The Option may be exercised by the executor or administrator
of the Optionee's estate or, if none, by the person(s) entitled to exercise the
Option under the Optionee's will or the laws of descent or distribution. If the
Option is not so exercised within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

            (e) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

      11.   Stock Purchase Rights.

            (a) Rights to Purchase. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept



                                      -9-
<PAGE>   10
such offer. The offer shall be accepted by execution of a Restricted Stock
Purchase Agreement in the form determined by the Administrator.

            (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator.

            (c) Other Provisions. The Restricted Stock Purchase Agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

            (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.

      12. Non-Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator, an Option or Stock Purchase Right may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee. If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

      13. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.

            (a) Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall



                                      -10-
<PAGE>   11
be made with respect to, the number or price of shares of Common Stock subject
to an Option or Stock Purchase Right.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse
as to all such Shares, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent it has not been
previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

            (c) Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or Stock Purchase Right becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully vested and exercisable for a
period of fifteen (15) days from the date of such notice, and the Option or
Stock Purchase Right shall terminate upon the expiration of such period. For the
purposes of this paragraph, the Option or Stock Purchase Right shall be
considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option or Stock Purchase Right immediately prior to the merger or
sale of assets, the consideration (whether stock, cash, or other securities or
property) received in the merger or sale of assets by holders of Common Stock
for each Share held on the effective date of the transaction (and if holders
were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Stock Purchase Right, for each Share
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

      14. Date of Grant. The date of grant of an Option or Stock Purchase Right
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator. Notice of the determination shall be
provided to each Optionee within a reasonable time after the date of such grant.



                                      -11-
<PAGE>   12
      15. Amendment and Termination of the Plan.

            (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

            (b) Shareholder Approval. The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

            (c) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

      16.   Conditions Upon Issuance of Shares.

            (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right and the issuance and delivery of such Shares shall
comply with Applicable Laws and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

            (b) Investment Representations. As a condition to the exercise of an
Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

      17. Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

      18. Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

      19. Shareholder Approval. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

      25% of the Shares subject to the Option shall vest twelve months after the

<PAGE>   14

      Termination Period:

      This Option may be exercised for three months after Optionee ceases to be

II.   AGREEMENT

      A. Grant of Option.

            The Plan Administrator of the Company hereby grants to the Optionee
named in the Notice of Grant attached as Part I of this Agreement (the
"Optionee") an option (the "Option") to purchase the number of Shares, as set
forth in the Notice of Grant, at the exercise price per share set forth in the
Notice of Grant (the "Exercise Price"), subject to the terms and conditions of
the Plan, which is incorporated herein by reference. Subject to Section 15(c) of
the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

            If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code. However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

      B. Exercise of Option.

            (a) Right to Exercise. This Option is exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

            (b) Method of Exercise. This Option is exercisable by delivery of an
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to [TITLE] of the Company. The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

                      No Shares shall be issued pursuant to the exercise of this
Option unless such issuance and exercise complies with Applicable Laws. Assuming
such compliance, for income tax purposes the Exercised Shares shall be
considered transferred to the Optionee on the date the Option is exercised with
respect to such Exercised Shares.



                                      -2-
<PAGE>   15
      C. Method of Payment.

            Payment of the aggregate Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Optionee:

             1. cash; or

             2. check; or

             3. consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

             4. surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

      D. Non-Transferability of Option.

            This Option may not be transferred in any manner otherwise than by
will or by the laws of descent or distribution and may be exercised during the
lifetime of Optionee only by the Optionee. The terms of the Plan and this Option
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

      E. Term of Option.

            This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with
the Plan and the terms of this Option Agreement.

      F. Tax Consequences.

            Some of the federal tax consequences relating to this Option, as of
the date of this Option, are set forth below. THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE
SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE
SHARES.

      G. Exercising the Option.

             1. Nonstatutory Stock Option. The Optionee may incur regular
federal income tax liability upon exercise of a NSO. The Optionee will be
treated as having received compensation income (taxable at ordinary income tax
rates) equal to the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price. If the
Optionee is an Employee or a former Employee, the Company will be required to
withhold from his or her compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to



                                      -3-
<PAGE>   16

honor the exercise and refuse to deliver Shares if such withholding amounts are
not delivered at the time of exercise.

             2. Incentive Stock Option. If this Option qualifies as an ISO, the
Optionee will have no regular federal income tax liability upon its exercise,
although the excess, if any, of the Fair Market Value of the Exercised Shares on
the date of exercise over their aggregate Exercise Price will be treated as an
adjustment to alternative minimum taxable income for federal tax purposes and
may subject the Optionee to alternative minimum tax in the year of exercise. In
the event that the Optionee ceases to be an Employee but remains a Service
Provider, any Incentive Stock Option of the Optionee that remains unexercised
shall cease to qualify as an Incentive Stock Option and will be treated for tax
purposes as a Nonstatutory Stock Option on the date three (3) months and one (1)
day following such change of status.

             3. Disposition of Shares.

                  (a) NSO. If the Optionee holds NSO Shares for at least one
year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

                  (b) ISO. If the Optionee holds ISO Shares for at least one
year after exercise and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price. Any additional gain will be taxed
as capital gain, short-term or long-term depending on the period that the ISO
Shares were held.

                  (c) Notice of Disqualifying Disposition of ISO Shares. If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition. The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

      H. Entire Agreement; Governing Law.

            The Plan is incorporated herein by reference. The Plan and this
Option Agreement constitute the entire agreement of the parties with respect to
the subject matter hereof and supersede in their entirety all prior undertakings
and agreements of the Company and Optionee with respect to the subject matter
hereof, and may not be modified adversely to the Optionee's interest except by
means of a writing signed by the Company and Optionee. This agreement is
governed by the internal substantive laws, but not the choice of law rules, of
California.

      I. NO GUARANTEE OF CONTINUED SERVICE.

            OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT
TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED,
BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). OPTIONEE FURTHER
ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED
HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS
OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING
PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT
OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE
PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

      By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
terms and conditions of the Plan and this Option Agreement. Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
Agreement and fully understands all provisions of the Plan and Option Agreement.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions relating to the Plan
and Option Agreement. Optionee further agrees to notify the Company upon any
change in the residence address indicated below.

                                    Recitals

      Pursuant to Pledgor's election to purchase Shares under the Option
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under
Pledgee's 1998 Stock Plan, and Pledgor's election under the terms of the Option
to pay for such shares with his promissory note (the "Note"), Pledgor has
purchased _________ shares of Pledgee's Common Stock (the "Shares") at a price
of $________ per share, for a total purchase price of $__________. The Note and
the obligations thereunder are as set forth in Exhibit C to the Option.

      NOW, THEREFORE, it is agreed as follows:

      1. Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor,
pursuant to the California Commercial Code, hereby pledges all of such Shares
(herein sometimes referred to as the "Collateral") represented by certificate
number ______, duly endorsed in blank or with executed stock powers, and
herewith delivers said certificate to the Secretary of Pledgee ("Pledgeholder"),
who shall hold said certificate subject to the terms and conditions of this
Security Agreement.

            The pledged stock (together with an executed blank stock assignment
for use in transferring all or a portion of the Shares to Pledgee if, as and
when required pursuant to this Security Agreement) shall be held by the
Pledgeholder as security for the repayment of the Note, and any extensions or
renewals thereof, to be executed by Pledgor pursuant to the terms of the Option,
and the Pledgeholder shall not encumber or dispose of such Shares except in
accordance with the provisions of this Security Agreement.

      2. Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

            (a) Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

            (b) Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the

to cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of

securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

      6. Default.  Pledgor shall be deemed to be in default of the Note and
of this Security Agreement in the event:

delinquent for a period of 10 days or more; or

            (b) Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

            In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

      7. Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the

negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

      12. Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

      13. Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein

                               AVANEX CORPORATION

                                 1998 STOCK PLAN

                       RESTRICTED STOCK PURCHASE AGREEMENT



      Unless otherwise defined herein, the terms defined in the Plan shall have
the same defined meanings in this Restricted Stock Purchase Agreement.

      WHEREAS the Purchaser named in the Notice of Grant, (the "Purchaser") is a
Service Provider, and the Purchaser's continued participation is considered by
the Company to be important for the Company's continued growth; and

      WHEREAS in order to give the Purchaser an opportunity to acquire an equity
interest in the Company as an incentive for the Purchaser to participate in the
affairs of the Company, the Administrator has granted to the Purchaser a Stock
Purchase Right subject to the terms and conditions of the Plan and the Notice of
Grant, which are incorporated herein by reference, and pursuant to this
Restricted Stock Purchase Agreement (the "Agreement").

      NOW THEREFORE, the parties agree as follows:

      1. Sale of Stock. The Company hereby agrees to sell to the Purchaser
and the Purchaser hereby agrees to purchase shares of the Company's Common Stock
(the "Shares"), at the per Share purchase price and as otherwise described in
the Notice of Grant.

      2. Payment of Purchase Price. The purchase price for the Shares may be
paid by delivery to the Company at the time of execution of this Agreement of
cash, a check, or some combination thereof.

      3. Repurchase Option.

            (a) In the event the Purchaser ceases to be a Service Provider for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (see Section 4), the Company
shall, upon the date of such termination (as reasonably fixed and determined by
the Company) have an irrevocable, exclusive option (the "Repurchase Option") for
a period of sixty (60) days from such date to repurchase up to that number of
shares which constitute the Unreleased Shares (as defined in Section 4) at the
original purchase price per share (the "Repurchase Price"). The Repurchase
Option shall be exercised by the Company by delivering written notice to the
Purchaser or the Purchaser's executor (with a copy to the Escrow Holder) AND, at
the Company's option, (i) by delivering to the Purchaser or the Purchaser's
executor a check in the amount of the aggregate Repurchase Price, or (ii) by
canceling an amount of the Purchaser's



<PAGE>   28

indebtedness to the Company equal to the aggregate Repurchase Price, or (iii) by
a combination of (i) and (ii) so that the combined payment and cancellation of
indebtedness equals the aggregate Repurchase Price. Upon delivery of such notice
and the payment of the aggregate Repurchase Price, the Company shall become the
legal and beneficial owner of the Shares being repurchased and all rights and
interests therein or relating thereto, and the Company shall have the right to
retain and transfer to its own name the number of Shares being repurchased by
the Company.

            (b) Whenever the Company shall have the right to repurchase Shares
hereunder, the Company may designate and assign one or more employees, officers,
directors or shareholders of the Company or other persons or organizations to
exercise all or a part of the Company's purchase rights under this Agreement and
purchase all or a part of such Shares. If the Fair Market Value of the Shares to
be repurchased on the date of such designation or assignment (the "Repurchase
FMV") exceeds the aggregate Repurchase Price of such Shares, then each such
designee or assignee shall pay the Company cash equal to the difference between
the Repurchase FMV and the aggregate Repurchase Price of such Shares.

      4. Release of Shares From Repurchase Option.

            (a)__________________________ percent (______%) of the Shares shall
be released from the Company's Repurchase Option [one year] after the Date of
Grant and __________________ percent (______%) of the Shares [at the end of each
month thereafter], provided that the Purchaser does not cease to be a Service
Provider prior to the date of any such release.

            (b) Any of the Shares that have not yet been released from the
Repurchase Option are referred to herein as "Unreleased Shares."

            (c) The Shares that have been released from the Repurchase Option
shall be delivered to the Purchaser at the Purchaser's request (see Section 6).

      5. Restriction on Transfer. Except for the escrow described in Section
6 or the transfer of the Shares to the Company or its assignees contemplated by
this Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until such Shares
are released from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

      6. Escrow of Shares.

            (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon repurchase by the Company pursuant to the Repurchase
Option, the Purchaser shall, upon execution of this Agreement, deliver and
deposit with an escrow holder designated by the Company (the "Escrow Holder")
the share certificates representing the Unreleased Shares, together with the
stock assignment duly endorsed in blank, attached hereto as Exhibit A-2. The
Unreleased Shares and stock assignment shall be held by the Escrow Holder,
pursuant to the Joint Escrow Instructions of the Company and Purchaser attached
hereto as Exhibit A-3, until such time as the Company's



                                      -2-
<PAGE>   29

Repurchase Option expires. As a further condition to the Company's obligations
under this Agreement, the Company may require the spouse of Purchaser, if any,
to execute and deliver to the Company the Consent of Spouse attached hereto as
Exhibit A-4.

            (b) The Escrow Holder shall not be liable for any act it may do or
omit to do with respect to holding the Unreleased Shares in escrow while acting
in good faith and in the exercise of its judgment.

            (c) If the Company or any assignee exercises the Repurchase Option
hereunder, the Escrow Holder, upon receipt of written notice of such exercise
from the proposed transferee, shall take all steps necessary to accomplish such
transfer.

            (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from the Repurchase
Option, upon request the Escrow Holder shall promptly cause a new certificate to
be issued for the released Shares and shall deliver the certificate to the
Company or the Purchaser, as the case may be.

            (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to the Shares while they are held in
escrow, including without limitation, the right to vote the Shares and to
receive any cash dividends declared thereon. If, from time to time during the
term of the Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Repurchase Option.

      7. Legends. The share certificate evidencing the Shares, if any, issued
hereunder shall be endorsed with the following legend (in addition to any legend
required under applicable state securities laws):

         THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT
BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.

      8. Adjustment for Stock Split. All references to the number of Shares
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, stock dividend or other change in the
Shares that may be made by the Company after the date of this Agreement.

      9. Tax Consequences. The Purchaser has reviewed with the Purchaser's
own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. The Purchaser understands that



                                      -3-
<PAGE>   30

the Purchaser (and not the Company) shall be responsible for the Purchaser's own
tax liability that may arise as a result of the transactions contemplated by
this Agreement. The Purchaser understands that Section 83 of the Internal
Revenue Code of 1986, as amended (the "Code"), taxes as ordinary income the
difference between the purchase price for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" includes the right of the Company to buy back the Shares
pursuant to the Repurchase Option. The Purchaser understands that the Purchaser
may elect to be taxed at the time the Shares are purchased rather than when and
as the Repurchase Option expires by filing an election under Section 83(b) of
the Code with the IRS within 30 days from the date of purchase. The form for
making this election is attached as Exhibit A-5 hereto.

            THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

      10. General Provisions.

            (a) This Agreement shall be governed by the internal substantive
laws, but not the choice of law rules of California. This Agreement, subject to
the terms and conditions of the Plan and the Notice of Grant, represents the
entire agreement between the parties with respect to the purchase of the Shares
by the Purchaser. Subject to Section 15(c) of the Plan, in the event of a
conflict between the terms and conditions of the Plan and the terms and
conditions of this Agreement, the terms and conditions of the Plan shall
prevail. Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Agreement.

            (b) Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

               Any notice to the Escrow Holder shall be sent to the Company's
address with a copy to the other party hereto.

            (c) The rights of the Company under this Agreement shall be
transferable to any one or more persons or entities, and all covenants and
agreements hereunder shall inure to the benefit of, and be enforceable by the
Company's successors and assigns. The rights and obligations of the Purchaser
under this Agreement may only be assigned with the prior written consent of the
Company.

            (d) Either party's failure to enforce any provision of this
Agreement shall not in any way be construed as a waiver of any such provision,
nor prevent that party from thereafter enforcing any other provision of this
Agreement. The rights granted both parties hereunder are



                                      -4-
<PAGE>   31

cumulative and shall not constitute a waiver of either party's right to assert
any other legal remedy available to it.

            (e) The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

            (f) PURCHASER ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES
PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED OR
PURCHASING SHARES HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT
THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE
SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED
ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT
ALL, AND SHALL NOT INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE PURCHASER'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

      2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate

      3. Purchaser irrevocably authorizes the Company to deposit with you any

authorities or rights of the parties executing or delivering or purporting to

                               AVANEX CORPORATION

                       FOUNDER'S STOCK PURCHASE AGREEMENT


     THIS AGREEMENT is made as of January 13, 1998, by and between Avanex
Corporation, a California corporation (the "COMPANY"), and Simon Xiaofan Cao
(the "PURCHASER").

     Whereas, Purchaser possesses certain Technology (as defined below) related
to the business of the Company which the Company's Board of Directors has
determined to have a value of $800.00.

     Whereas, Purchaser and the Company desire to assign the Technology to the
Company in consideration for the sale and issuance of shares of the Company's
common stock (as described below), and to sell additional shares of the
Company's common stock to Purchaser.

     The parties agree as follows:

     1.   Sale of Stock. The Company hereby agrees to sell to the Purchaser and
the Purchaser hereby agrees to purchase an aggregate of 1,800,000 shares of the
Company's Common Stock, no par value (the "SHARES") at a price of $0.001 per
share for an aggregate purchase price of $1,000.00, plus the assignment of all
of Purchaser's right, title and interest in and to the Technology as described
in Section 13 hereof.

     2.   Payment of Purchase Price. The payment of the purchase price shall be
by either cash, check, promissory notes payable to the Company, or an
assignment of all right, title and interest in certain property by Purchaser
to the company as provided in that certain Assignment of Proprietary Rights
between the Company and the Purchaser of even date herewith, or any combination
of these.

     3.   Repurchase Option. In the event of any voluntary or involuntary
termination of the Purchaser's employment by, or services to, the Company for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (as defined below in Section 4),
the Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option, but not the
obligation, for a period of 90 days from such date to repurchase all or any
portion of the Unreleased Shares (as defined below in Section 4) at such time
at the original purchase price per share (the "REPURCHASE PRICE"). The
Repurchase Option shall be exercisable by the Company by written notice to the
Purchaser or the Purchaser's executor (with a copy to the Escrow Agent, as
defined below in Section 6) and shall be exercisable, at the company's option,
(i) by delivery to the Purchaser or the Purchaser's executor with such notice
of a check in the amount of the purchase price for the Shares being
repurchased, or (ii) by cancellation by the Company of an amount of the
Purchaser's indebtedness, if any, to the Company equal to the purchase price
for the Shares being repurchased, or (iii) by a combination of (i) and (ii) so
that the combined payment and cancellation of indebtedness equals the
Repurchased Price times the number of shares to be repurchased (the "AGGREGATE
REPURCHASE PRICE"). Upon delivery of such notice and the payment of the
Aggregate Repurchase Price in any of the ways described above, the Company
shall become the legal and beneficial owner of the Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall
have the right to retain and transfer to its own name the number of Shares
being repurchased by the Company. The Repurchase Option set forth in this
Section may be assigned by the Company in whole or in part in its sole and
unfettered discretion.
<PAGE>   2
     4.   Release of Shares from Repurchase Option.

          (a)  As of the date of this Agreement, all of the Shares shall be
subject to the Company's repurchase option (the "REPURCHASE OPTION"). The
Shares shall be released from the Repurchase Option as follows:

               (i)  One quarter (1/4) of the Shares shall be released from the
Repurchase Option on January 13, 1999; and

               (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

          (b)  Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "UNRELEASED
SHARES".

          (c)  The Shares which have been released from the Repurchase Option
shall be delivered to the Purchaser at the Purchaser's request.

          (d)  Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released form the Repurchase Option on the same schedule as existed prior to the
Change of Control. For example, if a Change of Control occurs on a date where
25% of Purchaser's Shares have been released from the Company's Purchase Option,
then an additional 25% of the Shares shall be released from the Purchase Option
pursuant hereto. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

     For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:

               (i)  Any "person" (as such term is defined in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities
other than in a private financing transaction approved by the Board of
Directors;

               (ii) the direct or indirect sale or exchange by the shareholders
of the Company of all or substantially all of the stock of the Company;

               (iii) a merger or consolidation in which the Company is a party
and in which the shareholders of the Company before such merger or
consolidation do not retain, directly or indirectly, at a least majority of the
beneficial interest in the voting stock of the Company after such transaction;
or


                                      -2-
<PAGE>   3
               (iv)   the sale or disposition by the Company of all or
substantially all the Company's assets.

          (e)  Acceleration Upon Termination of Employment. In addition to the
Shares released from the Company's Repurchase Option pursuant to Section 4(d)
above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

     For the purposes of this Section 4(e), the following terms referred to in
this Agreement shall have the following meanings:

               (i)   Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

               (ii)  Disability. "Disability" shall mean that the Purchaser has
been unable to substantially perform his duties as the result of his incapacity
due to physical or mental illness, and such inability, at least 26 weeks after
its commencement, is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the Purchaser or the
Purchaser's legal representative (such agreement as to acceptability not to be
unreasonably withheld).

               (iii) Involuntary Termination. "Involuntary Termination" shall
mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the relocation of the Purchaser to a facility or a location more than 50
miles from the Purchaser's then present location, without the Purchaser's
express written consent; (vi) any purported termination of the Purchaser by the
Company which is not effected for death or Disability or for Cause, or any
purported termination for which the grounds relied upon are not valid; or (vii)
the failure of the Company to obtain the assumption of this agreement by any
successors contemplated in Section 4(f) below.

                                      -3-
<PAGE>   4
          (f)  Successors.

               (i)  Company's Successors. Any successor to the Company (whether
direct or indirect and whether by purchase, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Section 4 and agree expressly to
perform the obligations under this Section 4 in the same manner and to the same
extent as the Company would be required to perform such obligations in the
absence of a succession. For all purposes under this Section 4, the term
"COMPANY" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this Section
4(f)(i) or which becomes bound by the terms of this Agreement by operation of
law.

              (ii)  Purchaser's Successors. The terms of this Section 4 and all
rights of the Purchaser hereunder shall inure to the benefit of, and be
enforceable by, the Purchaser's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

     5.   Restriction on Transfer.

          (a)  Except for the escrow described below in Section 6, none of the
Shares or any beneficial interest therein shall be transferred, encumbered or
otherwise disposed of in any manner until the release of such shares from the
Repurchase Option in accordance with the provisions of this Agreement.

          (b)  Before any Shares may be sold or transferred (including transfer
by operation of law), such Shares shall first be offered to the Company (the
"RIGHT OF FIRST REFUSAL").

               (i)   Notice. In the event the Purchaser wishes to sell the
Shares, Purchaser shall deliver a notice ("Notice") to the Company stating (A)
his bona fide intention to sell or transfer such Shares, (B) the number of such
Shares to be sold or transferred, (C) the price for which he proposes to sell or
transfer such Shares, and (D) the name of the proposed purchaser or transferee.

              (ii)   Election to Purchase. Within thirty (30) days after receipt
of the Notice, the Company or its assignee may elect to purchase all or none of
the Shares to which the Notice refers, at the price per share specified in the
Notice. The purchase of the Shares in either such event shall occur at a closing
held at the Company's principal office at a mutually agreed upon time which in
no event shall be more than thirty (30) days following the end of the time
period in which the Company had to elect to purchase such Shares.

             (iii)  Sale of Shares by Purchaser. If all of the Shares to which
the Notice refers are not elected to be purchased, as provided in this Section
5(b), Purchaser may sell the Shares to any person named in the Notice at the
price specified in the Notice or at a higher price, provided that such sale or
transfer is consummated within sixty (60) days of the date of said Notice to the
Company, and provided, further, that any such sale is in accordance with all the
terms and conditions hereof.

              (iv)  Termination of Restrictions. Notwithstanding the provisions
of Section 5(a) above, the Company's Right of First Refusal shall terminate
immediately as to all Shares upon the occurrence of the first to occur of the
following events:

                                      -4-
<PAGE>   5
                    (A)  the acquisition of the Company by another entity by
means of the merger or consolidation of the Company with or into another
corporation in which the stock-holders of the Company immediately prior to such
merger or consolidation own less than 50% of the voting securities of the
surviving entity,

                    (B)  the sale of all or substantially all of the assets of
the Company, or

                    (C)  the date upon which a public market exists for the
Company's capital stock (or any other stock issued to purchasers in exchange for
the Shares purchased under this Agreement). For the purpose of this Agreement, a
"Public Market" shall be deemed to exist if (1) such stock is listed on a
national securities exchange (as that term is used in the Securities Exchange
Act of 1934), or (2) such stock is traded on the over-the-counter market and
prices are published daily on business days in a recognized financial journal.

               (v)  Assignment. Whenever the Company shall have the right to
purchase Shares under this Section 5, the Company may designate and assign one
or more employees, officers, directors or shareholders of the Company or other
persons or organizations to exercise all of the Company's purchase rights under
this Agreement and purchase all of such Shares; provided that if the fair market
value of the Shares to be purchased on the date of such designated or assignment
(the "Repurchase FMV") exceeds the purchase price of the Shares (determined as
described hereinabove) to be purchased, then each such designee or assignee
shall pay the Company cash equal to the difference between the Repurchase FMV
and the purchase price of the Shares which such designee or assignee shall have
the right to purchase.

               (vi) Exempt Transfers. The provisions of this Section 5 shall not
apply to a transfer of any Shares by Purchaser, either during his lifetime or on
death by will or intestacy to his ancestors, descendants or spouse, or any
custodian or trustee for the account of Purchaser or Purchaser's ancestors,
descendants or spouse; provided, in each such case that the transferee shall
receive and hold such Shares subject to all of the provisions of this Section 5
and there shall be no further transfer of such Shares except in accordance
herewith.

     6.   Escrow of Shares. Pursuant to the terms of the Joint Escrow
Instructions attached hereto as Exhibit B, the Shares issued under this
Agreement shall be held by the Escrow Agent (as defined in such Joint Escrow
Instructions) along with a stock assignment executed by the Purchaser in blank
in the form hereto as Exhibit A.

     7.   Investment Representations. In connection with the purchase of the
Shares, the Purchaser represents to the Company the following:

          (a)  The Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. The
Purchaser is purchasing the Shares for investment for the Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "SECURITIES ACT").



                                      -5-
<PAGE>   6
          (b)  The Purchaser understands that the Shares have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of the
Purchaser's investment intent as expressed herein. In this connection, the
Purchaser understands that, in the view of the Securities and Exchange
Commission (the "COMMISSION"), the statutory basis for such exemption may not be
present if the Purchaser's representations meant that the Purchaser's present
intention was to hold the Shares for a minimum capital gains period under
applicable tax statues, for a deferred sale, for a market rise, for a sale if
the market does not rise, or for a year or any other fixed period in the future.

          (c)  The Purchaser further acknowledges and understands that the
Shares must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. The
Purchaser further acknowledges and understands that the Company is under no
obligation to register the Shares. The Purchaser understands that the
certificate evidencing the Shares will be imprinted with a legend which
prohibits the transfer of the Shares unless they are registered or such
registration is not required in the opinion of counsel satisfactory to the
Company.

     8.   Stock Certificate Legends. The share certificate evidencing the Shares
issued hereunder shall be endorsed with the following legends:

          (a)  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.
     THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
     REGISTRATION OR ANY EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE
     AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
     TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
     OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE
     PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

          (b)  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED
     ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND
     THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE
     COMPANY.

          (c)  Any legend required by any applicable state securities laws.

     9.   Market Stand-Off Agreement. The Purchaser hereby agrees, if so
requested by the managing underwriters or the Company in connection with the
initial public offering of the Company's Common Stock, that, without the prior
written consent of such managing underwriters, the Purchaser will not offer,
sell, contract to sell, grant any option to purchase, make any short sale or
otherwise dispose of, assign any legal or beneficial interest in or make a
distribution of any capital stock of the Company held by or on behalf of the
Purchaser or beneficially owned by the Purchaser in accordance with the rules
and regulations of the Securities and Exchange Commission for a period of up to
180 days after the date of the final prospectus relating to the Company's
initial public offering.

     10.  Adjustment for Stock Split. All references to the number of Shares and
the purchaser price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, reverse stock split


                                      -6-
<PAGE>   7
or stock dividend or other similar change in the Shares which may be made by
the Company after the date of this Agreement.

     11.  Tax Consequences. The Purchaser has reviewed with the Purchaser's own
tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser
is relying solely on such advisors and not on any statements or
representations of the Company or any of its agents. The Purchaser understands
that the Purchaser (and not the Company) shall be responsible for the
Purchaser's own tax liability that may arise as a result of this investment or
the transactions contemplated by this Agreement. The Purchaser understands that
Section 83 of the Internal Revenue Code of 1986, as amended (the "CODE"), taxes
as ordinary income both (i) the difference between the fair market value of the
Shares when the Company granted the Purchaser the right to purchase the Shares
and the fair market value of the Shares on the date of this Agreement, and (ii)
the difference between the amount paid for the Shares and the fair market value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" includes the right of the Company to buy back the Shares
pursuant to its repurchase option. In the event the Company has registered
under the Exchange Act, "restriction" with respect to officers, directors and
10% shareholders could be subject to suit under Section 16(b) of the Exchange
Act. The Purchaser understands that the Purchaser may elect to be taxed at the
time the Shares are purchased rather than when and as the Company's repurchase
option or 16(b) period expires by filing an election under Section 83(b) of the
Code with the I.R.S. within 30 days from the date of purchase.

          THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

     12.  California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH
ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER
OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES
OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO
SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM
THE QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA
CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY
CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO
EXEMPT.

     13.  Assignment of Technology. In partial consideration for the sale and
issuance of the Stock by the Company to the Purchaser:

     (i)  Purchaser hereby irrevocably assigns, transfers and conveys to the
Company all of its right, title and interest in and to:

          (a)  all technical information, know-how, processes, procedures,
compositions, devices, methods, techniques, data, marks (and the goodwill
associated therewith), ideas, discoveries, trade secrets, copyrights or other
subject matter generally relating to micro-optic based broadband and low loss
Dispersion Compensators capable of compensating dispersion induced signal
distortion, and thermally


                                      -7-
<PAGE>   8
tunable WDM devices capable of wavelength tuning for applications such as
programmable ADD/DROP Modules and Optical Cross-Connect systems (collectively,
the "Technology"), including without limitation any and all invention(s)
disclosed in the Technology and all embodiments thereof (the "Inventions");

          (b)  all rights to apply in any and all countries of the world for
patents, certificates of inventions or other governmental grants on the
Inventions, including the right to apply for patents pursuant to the
International Convention for the Protection of Industrial Property or pursuant
to any other convention, treaty, agreement or understanding;

          (c)  any and all applications filed and any and all patents,
certificates of inventions or other governmental grants granted on the
Invention in the United States or any other country, including each and every
application filed and each and every patent granted on any application which is
a division, substitution or continuation of any of said applications
(collectively, the "Patents");

          (d)  each and every reissue or extension of any of the Patents;

          (e)  in and to each and every patent claim resulting from a
reexamination certificate for any and all of the Patents; and

          (f)  any and all causes of action relating to the enforcement of the
Technology and any and all other right or interest in or to the Technology, in
each case existing as of or arising after the Effective Date.

     (ii) Purchaser represents and warrants that (i) Purchaser is the owner of
the entire right, title, and interest in and to the Technology; (ii) Purchaser
has the sole right and authority to enter into this Agreement and grant the
rights hereunder; (iii) Purchaser has not previously granted and will not grant
any rights or licenses in the Technology; (iv) to the best of its knowledge,
there are no claims of third parties that would call into question the rights of
Purchaser to grant to the Company the rights contemplated hereunder; (v) as of
the Closing Date, Purchaser does not own any patents, patent applications,
technical information, know-how, processes, compositions, devices, methods,
techniques, data, market, ideas, discoveries, trade secrets, copyrights or other
intellectual property related to micro-optic based broadband and low loss
Dispersion Compensators capable of compensating dispersion induced signal
distortion, and thermally tunable WDM devices capable of wavelength tuning for
applications such as programmable ADD/DROP Modules and Optical Cross-Connect
systems except for the Technology assigned to the Company.

     (iii)     Purchaser agrees to execute any and all papers and documents, and
take such other actions as are reasonably requested by the Company, to evidence,
perfect or defend the foregoing assignment and fully implement the Company's
proprietary rights in the subject matter assigned hereunder, such as obtaining
and enforcing patents, and to fully cooperate in the prosecution, enforcement
and defense of such proprietary rights. Purchaser further agrees that if the
Company is unable, for any reason, to secure such signatures to apply for or to
pursue any application for any patent, copyright or other proprietary right
covering any Technology assigned to the Company above, then Purchaser hereby
irrevocably designates and appoints the Company and its duly authorized officers
and agents as Purchaser's agent and attorney-in-fact, to act for and in
Purchaser's behalf and stead to execute and file any such applications and


                                      -8-
<PAGE>   9
to do all other lawfully permitted acts to further the prosecution and issuance
of patents, copyright and other registrations thereon with the same legal force
and effect as if executed by Purchaser.

     14.  General Provisions.

          (a)  This Agreement shall be governed by the laws of the State of
California. This Agreement represents the entire agreement between the parties
with respect to the purchase of Common Stock by the Purchaser and may only be
modified or amended in writing signed by both parties.

          (b)  Any notice, demand or request required or permitted to be given
by either the Company or the Purchaser pursuant to the terms of this Agreement
shall be in writing and shall be deemed given when delivered personally or
deposited in the U.S. mail, First Class with postage prepaid, and addressed to
the parties at the addresses of the parties set forth at the end of this
Agreement or such other address as a party may request by notifying the other
in writing.

          (c)  The rights and benefits of the Company under this Agreement
shall be transferable to any one or more persons or entities, and all covenants
and agreements hereunder shall inure to the benefit of, and be enforceable by
the Company's successors and assigns. The rights and obligations of the
Purchaser under this Agreement may only be assigned with the prior written
consent of the Company and any purported transfer otherwise shall be null and
void.

          (d)  Either party's failure to enforce any provision or provisions of
this Agreement shall not in any way be construed as a waiver of any such
provision or provisions, nor prevent that party thereafter from enforcing each
and every other provision of this Agreement. The rights granted both parties
herein are cumulative and shall not constitute a waiver of either party's right
to assert all other legal remedies available to it under the circumstances.

          (e)  The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

          (f)  PURCHASER ACKNOWLEDGES AND AGREES THAT THE LAPSING OF THE

SERVICE AS AN "AT WILL" EMPLOYEE OF THE COMPANY (AND NOT THROUGH THE ACT OF
BEING HIRED OR PURCHASING SHARES HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE
REPURCHASE OPTION SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR
IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS AN EMPLOYEE FOR SUCH PERIOD, FOR ANY
PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH THE COMPANY'S RIGHT TO
TERMINATE PURCHASER'S EMPLOYMENT AT ANY TIME, WITH OR WITHOUT CAUSE.

          (g)  Purchaser has reviewed this Agreement in its entirety, has had
an opportunity to obtain the advice of counsel prior to executing this
Agreement and fully understands all provisions of this Agreement.

Attention: Judith M. O'Brien

Ladies and Gentlemen:

     As escrow agent (the "Escrow Agent") for both Avanex Corporation, a
California corporation (the "Company"), and the undersigned purchaser of stock
of the Company (the "Purchaser"), you are hereby authorized and directed to hold
the documents delivered to you pursuant to the terms of that certain Founder
Stock Purchase Agreement ("Agreement") between the Company and the undersigned
(the "Escrow"), in accordance with the following instructions:

     1.   In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the
Company's Repurchase Option (as defined in the Agreement), the Company shall
give to Purchaser and you a written notice specifying the number of shares of
stock to be purchased, the purchase price and the time for a closing hereunder
at the principal office of the Company. Purchaser and the Company hereby
irrevocably authorize and direct you to close the transaction contemplated by
such notice in accordance with the terms of said notice.

     2.   At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, cancellation of indebtedness or some combination thereof) for
the number of shares of stock being purchased pursuant to the exercise of the
Company's repurchase option.

     3.   Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this Escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky
authority of any required applications for consent to, or notice of transfer of,
the securities. Subject to the provisions




<PAGE>   14
of the Agreement and of this Escrow Agreement, Purchaser shall exercise all
rights and privileges of a shareholder of the Company while the stock is held by
you.

     4.   Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's repurchase option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's repurchase option.
Within 90 days after cessation of Purchaser's continuous employment by the
Company, or any parent or subsidiary of the Company, you will deliver to
Purchaser a certificate or certificates representing the aggregate number of
shares held or issued pursuant to the Agreement and not purchased by the Company
or its assignees pursuant to exercise of the Company's repurchase option.

     5.   If at the time of termination of this escrow you should have in your
possession any documents, securities or other property belonging to Purchaser,
you shall deliver all of the same to Purchaser and shall be discharged of all
further obligations hereunder.

     6.   Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

     7.   You shall be obligated only for the performance of such duties as are
specifically set forth herein and may rely and shall be protected in relying or
refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith,
and any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

     8.   You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court. In
case you obey or comply with any such order, judgment or decree, you shall not
be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

     9.   You shall not be liable in any respect on account of the identity,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

     10.  You shall not be liable for the outlawing of any rights under the
Statute of Limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

     11.  You shall be entitled to employ such legal counsel and other experts
as you may deem necessary properly to advise you in connection with your
obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.


                                      -2-
<PAGE>   15
     12.  Your responsibilities as Escrow Agent shall terminate if you shall
cease to be an officer or agent of the Company or if you shall resign by written
notice to each party. In the event of any such termination, the Company shall
appoint a successor Escrow Agent.

     13.  If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

     14.  It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the securities held
by you hereunder, you are authorized and directed to retain in your possession
without liability to anyone all or any part of said securities until such
disputes have been settled either by mutual written agreement of the parties
concerned or by a final order, decree or judgment of a court of competent
jurisdiction after the time for appeal has expired and no appeal has been
perfected, but you shall be under no duty whatsoever to institute or defend any
such proceedings.

     15.  Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in
the United States Post Office, by registered or certified mail with postage and
fees prepaid, addressed to each of the other parties thereunto entitled at the

                       RESTRICTED STOCK PURCHASE AGREEMENT

        Unless otherwise defined herein, the terms defined in the 1998 Stock
Plan shall have the same defined meanings in this Restricted Stock Purchase
Agreement (the "Agreement").

I.      NOTICE OF GRANT OF STOCK PURCHASE RIGHT

        WALTER ALESSANDRINI

        You have been granted the right to purchase Common Stock of the Company,
subject to the terms and conditions of the Plan and this Agreement, as follows:

        Date of Grant                       October 8, 1999

        Exercise Price Per Share            $0.58

        Total Number of Shares Subject      347,706
        to This Stock Purchase Right

        Expiration Date                     January 6, 2000

        YOU MUST EXERCISE THIS STOCK PURCHASE RIGHT BEFORE THE EXPIRATION DATE
OR IT WILL TERMINATE AND YOU WILL HAVE NO FURTHER RIGHT TO PURCHASE THE SHARES.

Non-Transferability of Stock Purchase Right.

        This Stock Purchase Right may not be transferred in any manner otherwise
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Optionee only by Optionee. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

II.     AGREEMENT

        1. Sale of Stock. The Company hereby agrees to sell to the individual
named in the Notice of Grant of Stock Purchase Right (the "Purchaser"), and the
Purchaser hereby agrees to purchase the number of Shares set forth in the Notice
of Grant of Stock Purchase Right, at the exercise price per share set forth in
the Notice of Grant of Stock Purchase Right (the "Exercise Price"), and subject
to the terms and conditions of the Plan, which is incorporated herein by
reference. Subject to 14(c) of the Plan, in the event of a conflict between the
terms and conditions of the Plan and this Agreement, the terms and conditions of
the Plan shall prevail.

        2. Payment of Purchase Price. Purchaser herewith delivers to the Company
the aggregate Exercise Price for the Shares by cash or check.

        3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit B.

        4. Repurchase Option.

               (a) In the event the Purchaser's continuous status as a Service
Provider terminates for any or no reason (including death or Disability), the
Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option for a period
of sixty (60) days from such date to repurchase up to that number of shares
which constitute the Unreleased Shares (as defined in Section 5) at the Exercise
Price per share (the "Repurchase Price") (the "Repurchase Option").

               (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

               (c) Whenever the Company shall have the right to repurchase the
Unreleased Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unreleased Shares. If the Fair Market Value of the
Unreleased Shares to be repurchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of the
Unreleased Shares, then each such designee or assignee shall pay the Company
cash equal to the difference between the Repurchase FMV and the aggregate
Repurchase Price of Unreleased Shares to be purchased.

               (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

       5. Release of Shares From Repurchase Option.

               (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

                      (i) One quarter (1/4) of the Shares shall be released from
the Repurchase Option on March 22, 2000; and

                      (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

               (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

               (c) The Shares which have been released from the Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request (see
Section 7).

               (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

        For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:

                      (i)  Any "person" (as such term is used in Sections 13(d)
and 14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities
other than in a private financing transaction approved by the Board of
Directors;

                      (ii) the direct or indirect sale or exchange by the
shareholders of the Company of all or substantially all of the stock of the
Company;

                                       3


<PAGE>   4

                      (iii) a merger or consolidation in which the Company is a
party and in which the shareholders of the Company before such merger or
consolidation do not retain, directly or indirectly, at a least majority of the
beneficial interest in the voting stock of the Company after such transaction;
or

                      (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

        For the purposes of this Section 5(e), the following terms referred to
in this Agreement shall have the following meanings:

                      (i)  Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

                      (ii) Disability. "Disability" shall mean that the
Purchaser has been unable to substantially perform his duties as the result of
his incapacity due to physical or mental illness, and such inability, at least
26 weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the
Purchaser or the Purchaser's legal representative (such agreement as to
acceptability not to be unreasonably withheld).

                      (iii) Involuntary Termination. "Involuntary Termination"
shall mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the


                                       4
<PAGE>   5



relocation of the Purchaser to a facility or a location more than 50 miles from
the Purchaser's then present location, without the Purchaser's express written
consent; (vi) any purported termination of the Purchaser by the Company which is
not effected for death or Disability or for Cause, or any purported termination
for which the grounds relied upon are not valid; or (vii) the failure of the
Company to obtain the assumption of this agreement by any successors
contemplated in Section 4(f) below.

               (f) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's
request.

        6. Restriction on Transfer. Except for the escrow described in 7 or
transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

        7. Escrow of Shares.

               (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

               (b) The Escrow Holder shall not be liable for any act it may do
or omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise of its judgment.

               (c) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

               (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

               (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time




                                       5
<PAGE>   6


during the term of the Company's Repurchase Option, there is (i) any stock
dividend, stock split or other change in the Shares, or (ii) any merger or sale
of all or substantially all of the assets or other acquisition of the Company,
any and all new, substituted or additional securities to which the Purchaser is
entitled by reason of the Purchaser's ownership of the Shares shall be
immediately subject to this escrow, deposited with the Escrow Holder and
included thereafter as "Shares" for purposes of this Agreement and the Company's
Repurchase Option.

        8. Company's Right of First Refusal. Before any Shares held by Purchaser
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

               (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

               (b) Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

               (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.

               (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or (iii) by any combination thereof within thirty (30) days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

               (e) Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided

                                       6


<PAGE>   7

further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, a new Notice shall be
given to the Company, and the Company and/or its assignees shall again be
offered the Right of First Refusal before any Shares held by the Holder may be
sold or otherwise transferred.

               (f) Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

               (g) Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the date of the first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the 1933 Act.

        9. Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

               (a) Purchaser understands and agrees that the Company shall cause
the legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
               SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
               UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL
               SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE
               OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
               RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A
               REPURCHASE OPTION

                                       7


<PAGE>   8

               HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE
               RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE ISSUER AND THE
               ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED
               AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER
               RESTRICTIONS, RIGHT OF FIRST REFUSAL AND REPURCHASE OPTION ARE
               BINDING ON TRANSFEREES OF THESE SHARES.

               (b) Stop-Transfer Notices. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

        10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

        11. Tax Consequences. Set forth below is a brief summary as of the date
of grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

               (a) Exercise of Stock Purchase Right. Generally, no income will
be recognized by Purchaser in connection with the exercise of the stock
purchaser right for shares subject to the Repurchase Option, unless an election
under Section 83(b) of the Code is filed with the Internal Revenue Service
within 30 days of the date of exercise of the right to purchase stock. The form
for making this election is attached as Exhibit A-4 hereto. Otherwise, as the
Company's repurchase right lapses, Purchaser will recognize compensation income
in an amount equal to the difference between the Fair Market Value of the stock
at the time the Company's repurchase right lapses and the amount paid for the
stock, if any (the "Spread"). If Purchaser is an Employee or former Employee,
the


                                       8


<PAGE>   9

Spread will be subject to tax withholding by the Company, and the Company will
be entitled to a tax deduction in the amount at the time the Purchaser
recognizes ordinary income with respect to a Stock Purchase Right.

                       INVESTMENT REPRESENTATION STATEMENT

             PURCHASER:      WALTER ALESSANDRINI

             COMPANY:        AVANEX CORPORATION

             SECURITY:       COMMON STOCK

             AMOUNT:         347,706

             DATE:           OCTOBER 8, 1999

        In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

        (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

        (b) reach an informed and knowledgeable decision to acquire the
Securities. Purchaser is acquiring these Securities for investment for
Purchaser's own account only and not with a view to, or for resale in connection
with, any "distribution" thereof within the meaning of the Securities Act of
1933, as amended (the "Securities Act").

        (c) Purchaser acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Purchaser's investment intent as expressed herein. In this connection,
Purchaser understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Purchaser's representation was predicated solely upon a present intention to
hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one (1) year or any other
fixed period in the future. Purchaser further understands that the Securities
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
further acknowledges and understands that the Company is under no obligation to
register the Securities. Purchaser understands that the certificate evidencing
the Securities will be imprinted with a legend which prohibits the transfer of
the Securities unless they are registered or such registration is not required
in the opinion of counsel satisfactory to the Company, a legend prohibiting
their transfer without the consent of the Commissioner of Corporations of the
State of California and any other legend required under applicable state
securities laws.

        (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities"


<PAGE>   20

acquired, directly or indirectly from the issuer thereof, in a non-public
offering subject to the satisfaction of certain conditions. Rule 701 provides
that if the issuer qualifies under Rule 701 at the time of the grant of the
Stock Purchase Right to the Purchaser, the exercise will be exempt from
registration under the Securities Act. In the event the Company becomes subject
to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market
stand-off agreement may require) the Securities exempt under Rule 701 may be
resold, subject to the satisfaction of certain of the conditions specified by
Rule 144, including: (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and,
in the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of Securities being sold during any three (3)
month period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (e) Purchaser further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                               SECURITY AGREEMENT

        This Security Agreement is made as of October 8, 1999 between Avanex
Corporation ("Pledgee") and Walter Alessandrini ("(Pledgor").

                                    Recitals

        Pursuant to Pledgor's election to purchase Shares under the Restricted
Stock Purchase Agreement dated April 30, 1999 (the "Agreement"), between Pledgor
and Pledgee under Pledgee's 1998 Stock Plan, and the Pledgor's election under
the terms of the Agreement to pay for such shares with his promissory note (the
"Note"), Pledgor has purchased 347,706 shares of Pledgee's Common Stock (the
"Shares") at a price of $0.58 per share, for a total purchase price of
$201,669.48.

        NOW, THEREFORE, it is agreed as follows:

        1. Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Agreement, Pledgor, pursuant to
the California Commercial Code, hereby pledges all of such Shares (herein
sometimes referred to as the "Collateral") represented by certificate number 13
duly endorsed in blank or with executed stock powers, and herewith delivers said
certificate to Wilson Sonsini Goodrich & Rosati, Professional Corporation
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

        The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and extensions or renewals thereof,
to be executed by Pledgor pursuant to the terms of the Agreement, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

        2. Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

               a. Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

               b. Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.

               c. Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within the meaning of the regulations under Part 207
of Title 12 of the Code of Federal Regulations


<PAGE>   25


("Regulation G"), Pledgor agrees to cooperate with Pledgee in making any
amendments to the Note or providing any additional collateral as may be
necessary to comply with such regulations.

        3. Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

        4. Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        5. Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

        6. Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

        In the case of an event of Default, as set forth above, Pledgee shall
have the right to accelerate payment of the Note upon notice to Pledgor, and
Pledgee shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

        7. Release of Collateral. Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

        9. Term. The within pledge of Shares shall continue until the payment of
all indebtedness secured hereby, at which time the remaining pledged stock shall
be promptly delivered to Pledgor, subject to the provisions for prior release of
a portion of the Collateral as provided in paragraph 7 above.

        10. Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

        11. Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

        12. Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

        13. Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein
shall be deemed to include, for all purposes, the respective designees,
successors, assigns, heirs, executors and administrators.

        14. Governing Law. This Security Agreement shall be interpreted and
governed under the laws of the State of California.

Agreement (the "Agreement").

I.      NOTICE OF GRANT OF STOCK PURCHASE RIGHT

        You have been granted the right to purchase Common Stock of the Company,

        to This Stock Purchase Right

        Expiration Date                     June 26, 1999

        YOU MUST EXERCISE THIS STOCK PURCHASE RIGHT BEFORE THE EXPIRATION DATE
OR IT WILL TERMINATE AND YOU WILL HAVE NO FURTHER RIGHT TO PURCHASE THE SHARES.

Non-Transferability of Stock Purchase Right.

        This Stock Purchase Right may not be transferred in any manner otherwise
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Optionee only by Optionee. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors

a conflict between the terms and conditions of the Plan and this Agreement, the
terms and conditions of the Plan shall prevail.


<PAGE>   2
        2.      Payment of Purchase Price. Purchaser herewith delivers to the
Company the aggregate Exercise Price for the Shares by cash or check.

        3.      Purchaser's Representations. In the event the Shares have not
been registered under the Securities Act of 1933, as amended, at the time this
Stock Purchase Right is exercised, the Optionee shall, if required by the
Company, concurrently with the exercise of all or any portion of this Stock
Purchase Right, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit B.

        4.      Repurchase Option.

                (a)     In the event the Purchaser's continuous status as a
Service Provider terminates for any or no reason (including death or
Disability), the Company shall, upon the date of such termination (as reasonably
fixed and determined by the Company), have an irrevocable, exclusive option for
a period of sixty (60) days from such date to repurchase up to that number of
shares which constitute the Unreleased Shares (as defined in Section 5) at the
Exercise Price per share (the "Repurchase Price") (the "Repurchase Option").

                (b)     The Repurchase Option shall be exercised by the Company
by delivering written notice to the Purchaser or the Purchaser's executor (with
a copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

                (c)     Whenever the Company shall have the right to repurchase
the Unreleased Shares hereunder, the Company may designate and assign one or
more employees, officers, directors or shareholders of the Company or other
persons or organizations to exercise all or a part of the Company's Repurchase
Option to purchase all or a part of the Unreleased Shares. If the Fair Market
Value of the Unreleased Shares to be repurchased on the date of such designation
or assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of
the Unreleased Shares, then each such designee or assignee shall pay the Company
cash equal to the difference between the Repurchase FMV and the aggregate
Repurchase Price of Unreleased Shares to be purchased.

                (d)     If the Company or its assignee does not elect to
exercise the Repurchase Option conferred above by giving the requisite notice
within ninety (90) days following Purchaser's termination as a Service Provider,
the Repurchase Option shall terminate.

        5. Release of Shares From Repurchase Option.

               (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

                      (i) One quarter (1/4) of the Shares shall be released from
the Repurchase Option on March 22, 2000; and

                      (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

               (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

               (c) The Shares which have been released from the Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request (see
Section 7).

               (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

        For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:

                      (i) Any "person" (as such term is used in Sections 13(d)
and 14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities

                      (ii) the direct or indirect sale or exchange by the
shareholders of the Company of all or substantially all of the stock of the
Company;

                      (iii) a merger or consolidation in which the Company is a
party and in which the shareholders of the Company before such merger or
consolidation do not retain, directly or indirectly, at a least majority of the
beneficial interest in the voting stock of the Company after such transaction;
or

                      (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

        For the purposes of this Section 5(e), the following terms referred to
in this Agreement shall have the following meanings:

                      (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

                      (ii) Disability. "Disability" shall mean that the
Purchaser has been unable to substantially perform his duties as the result of
his incapacity due to physical or mental illness, and such inability, at least
26 weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the
Purchaser or the Purchaser's legal representative (such agreement as to
acceptability not to be unreasonably withheld).

                      (iii) Involuntary Termination. "Involuntary Termination"
shall mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written


                                       4


<PAGE>   5
consent, a material reduction by the Company in the base compensation of the
Purchaser as in effect immediately prior to such reduction, or the ineligibility
of the Purchaser to continue to participate in any long-term incentive plan of
the Company; (iv) a material reduction by the Company in the kind or level of
employee benefits to which the Purchaser is entitled immediately prior to such
reduction with the result that the Purchaser's overall benefits package is
significantly reduced; (v) the relocation of the Purchaser to a facility or a
location more than 50 miles from the Purchaser's then present location, without
the Purchaser's express written consent; (vi) any purported termination of the
Purchaser by the Company which is not effected for death or Disability or for
Cause, or any purported termination for which the grounds relied upon are not
valid; or (vii) the failure of the Company to obtain the assumption of this
agreement by any successors contemplated in Section 4(f) below.

               (f) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's
request.

        6. Restriction on Transfer. Except for the escrow described in 7 or
transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

        7. Escrow of Shares.

               (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

               (b) The Escrow Holder shall not be liable for any act it may do
or omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise of its judgment.

               (c) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.


                                       5


<PAGE>   6
               (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

               (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Company's Repurchase Option.

        8. Company's Right of First Refusal. Before any Shares held by Purchaser
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

               (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

               (b) Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

               (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.


                                       6


<PAGE>   7
               (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or (iii) by any combination thereof within thirty (30) days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

               (e) Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section shall continue to apply to
the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a
new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

               (f) Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

               (g) Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the date of the first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the 1933 Act.

        9. Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

               (a) Purchaser understands and agrees that the Company shall cause
the legends set forth below or legends substantially equivalent thereto, to be

any other legends that may be required by the Company or by applicable state or
federal securities laws:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933 (THE


                                       7


<PAGE>   8
               "ACT") AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED,
               PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT
               OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE
               SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION
               IS IN COMPLIANCE THEREWITH.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
               RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A
               REPURCHASE OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET
               FORTH IN THE RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE
               ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH
               MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH
               TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND REPURCHASE
               OPTION ARE BINDING ON TRANSFEREES OF THESE SHARES.

               (b) Stop-Transfer Notices. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

        10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

        11. Tax Consequences. Set forth below is a brief summary as of the date
of grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

               (a) Exercise of Stock Purchase Right. Generally, no income will
be recognized by Purchaser in connection with the exercise of the stock
purchaser right for shares subject to the Repurchase Option, unless an election
under Section 83(b) of the Code is filed with the Internal Revenue Service
within 30 days of the date of exercise of the right to purchase stock. The form
for making this election is attached as Exhibit A-4 hereto. Otherwise, as the
Company's repurchase right lapses, Purchaser will recognize compensation income
in an amount equal to the difference between the Fair Market Value of the stock
at the time the Company's repurchase right lapses and the amount paid for the
stock, if any (the "Spread"). If Purchaser is an Employee or former Employee,
the Spread will be subject to tax withholding by the Company, and the Company
will be entitled to a tax deduction in the amount at the time the Purchaser
recognizes ordinary income with respect to a Stock Purchase Right.

               (b) Disposition of Shares. Upon disposition of the Shares, any
gain or loss is treated as capital gain or loss. If the Shares are held for at
least one year, any gain realized on disposition of the shares will be treated
as long-term capital gain for federal income tax purposes. Long-term capital
gains are grouped and netted by holding periods. Net capital gains on assets
held for more than 12 months is capped at 20%. Capital losses are allowed in
full against capital gains, and up to $3,000 against other income.

        THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

        12. No Guarantee of Continued Service. PURCHASER ACKNOWLEDGES AND AGREES
THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO
4 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS SERVICE PROVIDER AT THE WILL OF
THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES HEREUNDER).
PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE PURCHASER'S
RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.


                                       9

        13. Notices. Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and

this Agreement or such other address as a party may request by notifying the
other in writing.

        Any notice to the Escrow Holder shall be sent to the Company's address
with a copy to the other party not sending the notice.

        14. No Waiver. Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor prevent that party from thereafter
enforcing each and every other provision of this Agreement. The rights granted
both parties herein are cumulative and shall not constitute a waiver of either
party's right to assert all other legal remedies available to it under the
circumstances.

        15. Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

        16. Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

        17. Governing Law; Severability. This Agreement is governed by the
internal substantive laws but not the choice of law rules, of California.

        18. Entire Agreement. The Plan is incorporated herein by reference. This
Agreement (including the exhibits referenced herein), the Plan, and the
Investment Representation Statement constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Purchaser with
respect to the subject matter hereof, and may not be modified adversely to the
Purchaser's interest except by means of a writing signed by the Company and
Purchaser.

        PURCHASER:    WALTER ALESSANDRINI

        COMPANY:      AVANEX CORPORATION

        SECURITY:     COMMON STOCK

        AMOUNT:       3,477,059

        DATE:         APRIL 30, 1999

        In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

        (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

        (b) reach an informed and knowledgeable decision to acquire the
Securities. Purchaser is acquiring these Securities for investment for
Purchaser's own account only and not with a view to, or for resale in connection
with, any "distribution" thereof within the meaning of the Securities Act of
1933, as amended (the "Securities Act").

        (c) Purchaser acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Purchaser's investment intent as expressed herein. In this connection,
Purchaser understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Purchaser's representation was predicated solely upon a present intention to
hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one (1) year or any other
fixed period in the future. Purchaser further understands that the Securities
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
further acknowledges and understands that the Company is under no obligation to
register the Securities. Purchaser understands that the certificate evidencing
the Securities will be imprinted with a legend which prohibits the transfer of
the Securities unless they are registered or such registration is not required
in the opinion of counsel satisfactory to the Company, a legend prohibiting
their transfer without the consent of the Commissioner of Corporations of the
State of California and any other legend required under applicable state
securities laws.


<PAGE>   21
        (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Stock Purchase Right to the Purchaser, the
exercise will be exempt from registration under the Securities Act. In the event
the Company becomes subject to the reporting requirements of Section 13 or 15(d)
of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such
longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of certain of
the conditions specified by Rule 144, including: (1) the resale being made
through a broker in an unsolicited "broker's transaction" or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of
certain public information about the Company, (3) the amount of Securities being
sold during any three (3) month period not exceeding the limitations specified
in Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (e) Purchaser further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                               SECURITY AGREEMENT

        This Security Agreement is made as of April 30, 1999 between Avanex
Corporation ("Pledgee") and Walter Alessandrini ("Pledgor").

                                    Recitals

        Pursuant to Pledgor's election to purchase Shares under the Restricted
Stock Purchase Agreement dated April 30, 1999 (the "Agreement"), between Pledgor
and Pledgee under Pledgee's 1998 Stock Plan, and the Pledgor's election under
the terms of the Agreement to pay for such shares with his promissory note (the
"Note"), Pledgor has purchased 3,477,059 shares of Pledgee's Common Stock (the
"Shares") at a price of $0.08 per share, for a total purchase price of
$278,164.72.

        NOW, THEREFORE, it is agreed as follows:

        1. Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Agreement, Pledgor, pursuant to
the California Commercial Code, hereby pledges all of such Shares (herein
sometimes referred to as the "Collateral") represented by certificate number 13
duly endorsed in blank or with executed stock powers, and herewith delivers said
certificate to Wilson Sonsini Goodrich & Rosati, Professional Corporation
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

        The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and extensions or renewals thereof,
to be executed by Pledgor pursuant to the terms of the Agreement, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

        2. Pledgor's Representations and Covenants. To induce Pledgee to enter

cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        5. Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in

        6. Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

for a period of 10 days or more; or

            b. Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

        In the case of an event of Default, as set forth above, Pledgee shall
have the right to accelerate payment of the Note upon notice to Pledgor, and
Pledgee shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

        7. Release of Collateral. Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein

                                                                  EXHIBIT 10.8.1
                               AVANEX CORPORATION

                            STOCK PURCHASE AGREEMENT


        THIS AGREEMENT is made as of July 22, 1999, by and between Avanex
Corporation, a California corporation (the "COMPANY"), and Paul Shi-Qi Jiang
(the "PURCHASER").


        The parties agree as follows:

        1. Sale of Stock. The Company hereby agrees to sell to the Purchaser and
the Purchaser hereby agrees to purchase an aggregate of 300,000 shares of the
Company's Common Stock, no par value (the "SHARES") at a price of $0.04 per
share for an aggregate purchase price of $12,000.00.

        2. Payment of Purchase Price. The payment of the purchase price shall be
by $300.00 in cash or check, and the balance by delivery of a promissory note in
the form attached hereto as EXHIBIT C, secured by the shares so purchased
pursuant to a Pledge Agreement in the form attached hereto as EXHIBIT D.

        3. Repurchase Option. In the event of any voluntary or involuntary
termination of the Purchaser's employment by, or services to, the Company for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (as defined below in Section 4),
the Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option, but not the
obligation, for a period of 90 days from such date to repurchase all or any
portion of the Unreleased Shares (as defined below in Section 4) at such time at
the original purchase price per share (the "REPURCHASE PRICE"). The Repurchase
Option shall be exercisable by the Company by written notice to the Purchaser or
the Purchaser's executor (with a copy to the Escrow Agent, as defined below in
Section 6) and shall be exercisable, at the Company's option, (i) by delivery to
the Purchaser or the Purchaser's executor with such notice of a check in the
amount of the purchase price for the Shares being repurchased, or (ii) by
cancellation by the Company of an amount of the Purchaser's indebtedness, if
any, to the Company equal to the purchase price for the Shares being
repurchased, or (iii) by a combination of (i) and (ii) so that the combined
payment and cancellation of indebtedness equals the Repurchase Price times the
number of shares to be repurchased (the "AGGREGATE REPURCHASE PRICE"). Upon
delivery of such notice and the payment of the Aggregate Repurchase Price in any
of the ways described above, the Company shall become the legal and beneficial
owner of the Shares being repurchased and all rights and interests therein or
relating thereto, and the Company shall have the right to retain and transfer to
its own name the number of Shares being repurchased by the Company. The
Repurchase Option set forth in this Section may be assigned by the Company in
whole or in part in its sole and unfettered discretion.

        4. Release of Shares From Repurchase Option.

               (a) The Shares shall vest to Purchaser and be released from the
Company's repurchase option as follows: Provided that Purchaser maintains a
continuous status as a Service Provider of the Company, 25% of the Shares shall
be released from the Company's Repurchase Option on the one year anniversary of
the Vesting Commencement Date and an additional 1/48th of the Shares



<PAGE>   2

shall be released from the Company's Repurchase Option on the last day of each
full calendar month thereafter. Notwithstanding the foregoing, upon any Change
of Control (as herein defined) that number of Unreleased Shares, if any, which,
when aggregated with any Shares previously released from the Repurchase Option,
are required to equal fifty percent (50%) of the Shares shall be released from
the Repurchase Option on the date the event constituting a Change of Control is
consummated. The balance of the Shares subject to the Repurchase Option shall
continue to be released from the Repurchase Option on the same schedule as
existed prior to the Change of Control. For example, if a Change of Control
occurs on a date where 25% of Purchaser's Shares have been released from the
Company's Purchase Option, then an additional 25% of the Shares shall be
released from the Purchase Option pursuant hereto. If a Change of Control occurs
on a date where more than 50% of Purchaser's Shares have already been released
from the Company's Purchase Option, then no additional Shares shall be released
from the Purchase Option.

               (b) "Change of Control" shall mean any of the following: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the shareholders of the Company of more than fifty percent (50%)
of the voting stock of the Company, (ii) a merger or consolidation of the
Company with any other corporation which results in the voting securities of the
Company outstanding immediately prior thereto representing (either by remaining
outstanding or by being converted into voting securities of the surviving entity
or its parent) less than fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity (or
its parent) outstanding immediately after such merger or consolidation, or (iii)
the approval by the shareholders of the Company of a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all the Company's assets.

               (c) Any of the Shares which have not yet been released from the
Company's repurchase option are referred to herein as "Unreleased Shares."

               (d) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's request
(see Section 3).

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Repurchase Option upon the date of such termination.

        For the purposes of this Section 4(e), the following terms referred to
in this Agreement shall have the following meanings:

                    (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

               (ii) Disability. "Disability" shall mean that the Purchaser has
been unable to substantially perform his duties as the result of his incapacity
due to physical or mental illness, and



                                      -2-
<PAGE>   3

such inability, at least 26 weeks after its commencement, is determined to be
total and permanent by a physician selected by the Company or its insurers and
acceptable to the Purchaser or the Purchaser's legal representative (such
agreement as to acceptability not to be unreasonably withheld).

               (iii) Involuntary Termination. "Involuntary Termination" shall
mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the relocation of the Purchaser to a facility or a location more than 50
miles from the Purchaser's then present location, without the Purchaser's
express written consent; (vi) any purported termination of the Purchaser by the
Company which is not effected for death or Disability or for Cause, or any
purported termination for which the grounds relied upon are not valid; or (vii)
the failure of the Company to obtain the assumption of this agreement by any
successors contemplated in Section 4(f) below.

        (f) Successors.

               (i) Company's Successors. Any successor to the Company (whether
direct or indirect and whether by purchase, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Section 4 and agree expressly to
perform the obligations under this Section 4 in the same manner and to the same
extent as the Company would be required to perform such obligations in the
absence of a succession. For all purposes under this Section 4, the term
"COMPANY" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this Section
4(f)(i) or which becomes bound by the terms of this Agreement by operation of
law.

               (ii) Purchaser's Successors. The terms of this Section 4 and all
rights of the Purchaser hereunder shall inure to the benefit of, and be
enforceable by, the Purchaser's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

        5. Restriction on Transfer.

               (a) Except for the escrow described below in Section 6, none of
the Shares or any beneficial interest therein shall be transferred, encumbered
or otherwise disposed of in any manner until the release of such Shares from the
Repurchase Option in accordance with the provisions of this Agreement.



                                      -3-
<PAGE>   4

               (b) Before any Shares may be sold or transferred (including
transfer by operation of law), such Shares shall first be offered to the Company
(the "RIGHT OF FIRST REFUSAL").

                    (i) Notice. In the event the Purchaser wishes to sell the
Shares, Purchaser shall deliver a notice ("Notice") to the Company stating (A)
his bona fide intention to sell or transfer such Shares, (B) the number of such
Shares to be sold or transferred, (C) the price for which he proposes to sell or
transfer such Shares, and (D) the name of the proposed purchaser or transferee.

                    (ii) Election to Purchase. Within thirty (30) days after
receipt of the Notice, the Company or its assignee may elect to purchase all or
none of the Shares to which the Notice refers, at the price per share specified
in the Notice. The purchase of the Shares in either such event shall occur at a
closing held at the Company's principal office at a mutually agreed upon time
which in no event shall be more than thirty (30) days following the end of the
time period in which the Company had to elect to purchase such Shares.

                    (iii) Sale of Shares by Purchaser. If all of the Shares to
which the Notice refers are not elected to be purchased, as provided in this
Section 5(b), Purchaser may sell the Shares to any person named in the Notice at
the price specified in the Notice or at a higher price, provided that such sale
or transfer is consummated within sixty (60) days of the date of said Notice to
the Company, and provided, further, that any such sale is in accordance with all
the terms and conditions hereof.

                    (iv) Termination of Restrictions. Notwithstanding the
provisions of Section 5(a) above, the Company's Right of First Refusal shall
terminate immediately as to all Shares upon the occurrence of the first to occur
of the following events:

                         (A) the acquisition of the Company by another entity by
means of the merger or consolidation of the Company with or into another
corporation in which the stock-holders of the Company immediately prior to such
merger or consolidation own less than 50% of the voting securities of the
surviving entity,

                         (B) the sale of all or substantially all of the assets
of the Company, or

                         (C) the date upon which a public market exists for the
Company's capital stock (or any other stock issued to purchasers in exchange for
the Shares purchased under this Agreement). For the purpose of this Agreement, a
"Public Market" shall be deemed to exist if (1) such stock is listed on a
national securities exchange (as that term is used in the Securities Exchange
Act of 1934), or (2) such stock is traded on the over-the-counter market and
prices are published daily on business days in a recognized financial journal.

                    (v) Assignment. Whenever the Company shall have the right to
purchase Shares under this Section 5, the Company may designate and assign one
or more employees, officers, directors or shareholders of the Company or other
persons or organizations to exercise all of the Company's purchase rights under
this Agreement and purchase all of such Shares; provided that if the fair market
value of the Shares to be purchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the purchase price of the Shares
(determined as described hereinabove) to be purchased, then each such designee
or assignee shall pay the Company cash equal to the difference



                                      -4-
<PAGE>   5

between the Repurchase FMV and the purchase price of the Shares which such
designee or assignee shall have the right to purchase.

                    (vi) Exempt Transfers. The provisions of this Section 5
shall not apply to a transfer of any Shares by Purchaser, either during his
lifetime or on death by will or intestacy to his ancestors, descendants or
spouse, or any custodian or trustee for the account of Purchaser or Purchaser's
ancestors, descendants or spouse; provided, in each such case that the
transferee shall receive and hold such Shares subject to all of the provisions
of this Section 5 and there shall be no further transfer of such Shares except
in accordance herewith.

        6. Escrow of Shares. Pursuant to the terms of the Joint Escrow
Instructions attached hereto as EXHIBIT B, the Shares issued under this
Agreement shall be held by the Escrow Agent (as defined in such Joint Escrow
Instructions) along with a stock assignment executed by the Purchaser in blank
in the form attached hereto as EXHIBIT A.

        7. Investment Representations. In connection with the purchase of the
Shares, the Purchaser represents to the Company the following:

               (a) The Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. The
Purchaser is purchasing the Shares for investment for the Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "SECURITIES ACT").

               (b) The Purchaser understands that the Shares have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of the
Purchaser's investment intent as expressed herein. In this connection, the
Purchaser understands that, in the view of the Securities and Exchange
Commission (the "COMMISSION"), the statutory basis for such exemption may not be
present if the Purchaser's representations meant that the Purchaser's present
intention was to hold the Shares for a minimum capital gains period under
applicable tax statutes, for a deferred sale, for a market rise, for a sale if
the market does not rise, or for a year or any other fixed period in the future.

               (c) The Purchaser further acknowledges and understands that the
Shares must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. The
Purchaser further acknowledges and understands that the Company is under no
obligation to register the Shares. The Purchaser understands that the
certificate evidencing the Shares will be imprinted with a legend which
prohibits the transfer of the Shares unless they are registered or such
registration is not required in the opinion of counsel satisfactory to the
Company.

        8. Stock Certificate Legends. The share certificate evidencing the
Shares issued hereunder shall be endorsed with the following legends:

               (a) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
        ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933. THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN
        THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM



                                      -5-
<PAGE>   6

        UNDER SAID ACT. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE
        SHARES AND RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY
        WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
        SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
        CORPORATION.

               (b) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED
        ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY
        AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF
        THE COMPANY.

               (c) Any legend required by any applicable state securities laws.

        9. Market Stand-Off Agreement. The Purchaser hereby agrees, if so
requested by the managing underwriters or the Company in connection with the
initial public offering of the Company's Common Stock, that, without the prior
written consent of such managing underwriters, the Purchaser will not offer,
sell, contract to sell, grant any option to purchase, make any short sale or
otherwise dispose of, assign any legal or beneficial interest in or make a
distribution of any capital stock of the Company held by or on behalf of the
Purchaser or beneficially owned by the Purchaser in accordance with the rules
and regulations of the Securities and Exchange Commission for a period of up to
180 days after the date of the final prospectus relating to the Company's
initial public offering.

        10. Adjustment for Stock Split. All references to the number of Shares
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, reverse stock split or stock dividend or
other similar change in the Shares which may be made by the Company after the
date of this Agreement.

        11. Tax Consequences. The Purchaser has reviewed with the Purchaser's
own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. The Purchaser understands that the Purchaser
(and not the Company) shall be responsible for the Purchaser's own tax liability
that may arise as a result of this investment or the transactions contemplated
by this Agreement. The Purchaser understands that Section 83 of the Internal
Revenue Code of 1986, as amended (the "CODE"), taxes as ordinary income both (i)
the difference between the fair market value of the Shares when the Company
granted the Purchaser the right to purchase the Shares and the fair market value
of the Shares on the date of this Agreement, and (ii) the difference between the
amount paid for the Shares and the fair market value of the Shares as of the
date any restrictions on the Shares lapse. In this context, "restriction"
includes the right of the Company to buy back the Shares pursuant to its
repurchase option. In the event the Company has registered under the Exchange
Act, "restriction" with respect to officers, directors and 10% shareholders also
means the period after the purchase of the Shares during which such officers,
directors and 10% shareholders could be subject to suit under Section 16(b) of
the Exchange Act. The Purchaser understands that the Purchaser may elect to be
taxed at the time the Shares are purchased rather than when and as the Company's
repurchase option or 16(b) period expires by filing an election under Section
83(b) of the Code with the I.R.S. within 30 days from the date of purchase.

<PAGE>   7

               THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

        12. California Corporate Securities Law. THE SALE OF THE SECURITIES
WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE
COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH
SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR
PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT
FROM THE QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA
CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY
CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO
EXEMPT.

        13. General Provisions.

               (a) This Agreement shall be governed by the laws of the State of
California. This Agreement represents the entire agreement between the parties
with respect to the purchase of Common Stock by the Purchaser and may only be
modified or amended in writing signed by both parties.

               (b) Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

               (c) The rights and benefits of the Company under this Agreement
shall be transferable to any one or more persons or entities, and all covenants
and agreements hereunder shall inure to the benefit of, and be enforceable by
the Company's successors and assigns. The rights and obligations of the
Purchaser under this Agreement may only be assigned with the prior written
consent of the Company and any purported transfer otherwise shall be null and
void.

               (d) Either party's failure to enforce any provision or provisions
of this Agreement shall not in any way be construed as a waiver of any such
provision or provisions, nor prevent that party thereafter from enforcing each
and every other provision of this Agreement. The rights granted both parties
herein are cumulative and shall not constitute a waiver of either party's right
to assert all other legal remedies available to it under the circumstances.

               (e) The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

               (f) PURCHASER ACKNOWLEDGES AND AGREES THAT THE LAPSING OF THE
REPURCHASE OPTION PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING
SERVICE AS AN "AT WILL" EMPLOYEE OF THE COMPANY (AND NOT THROUGH THE ACT OF
BEING HIRED OR PURCHASING SHARES HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE



                                      -7-
<PAGE>   8

TRANSACTIONS CONTEMPLATED HEREUNDER AND THE REPURCHASE OPTION SCHEDULE SET FORTH
HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT
AS AN EMPLOYEE FOR SUCH PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE WITH THE COMPANY'S RIGHT TO TERMINATE PURCHASER'S EMPLOYMENT AT ANY
TIME, WITH OR WITHOUT CAUSE.

               (g) Purchaser has reviewed this Agreement in its entirety, has
had an opportunity to obtain the advice of counsel prior to executing this
Agreement and fully understands all provisions of this Agreement.

Attention:  Judith M. O'Brien

Ladies and Gentlemen:

        As escrow agent (the "Escrow Agent") for both Avanex Corporation, a
California corporation (the "Company"), and the undersigned purchaser of stock
of the Company (the "Purchaser"), you are hereby authorized and directed to hold
the documents delivered to you pursuant to the terms of that certain Stock
Purchase Agreement ("Agreement") between the Company and the undersigned (the
"Escrow"), in accordance with the following instructions:

        1. In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the Company's
Repurchase Option (as defined in the Agreement), the Company shall give to
Purchaser and you a written notice specifying the number of shares of stock to
be purchased, the purchase price and the time for a closing hereunder at the
principal office of the Company. Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

        2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, cancellation of indebtedness or some combination thereof) for the
number of shares of stock being purchased pursuant to the exercise of the
Company's repurchase option.

        3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this Escrow to execute with respect
to such securities all documents necessary or appropriate to make such

the securities. Subject to the provisions of the Agreement and of this Escrow
Agreement, Purchaser shall exercise all rights and privileges of a shareholder
of the Company while the stock is held by you.

        4. Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's repurchase option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's repurchase option.
Within 90 days after cessation of Purchaser's continuous employment by the
Company, or any parent or subsidiary of the Company, you will deliver to
Purchaser a certificate or certificates representing the aggregate number of
shares held or issued pursuant to the Agreement and not purchased by the Company
or its assignees pursuant to exercise of the Company's repurchase option.

        5. If at the time of termination of this escrow you should have in your
possession any documents, securities or other property belonging to Purchaser,
you shall deliver all of the same to Purchaser and shall be discharged of all
further obligations hereunder.

        6. Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith,
and any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

        8. You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court. In
case you obey or comply with any such order, judgment or decree, you shall not
be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

        9. You shall not be liable in any respect on account of the identity,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

as you may deem necessary properly to advise you in connection with your
obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.

        12. Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be an officer or agent of the Company or if you shall resign
by written notice to each party. In the event of any such termination, the
Company shall appoint a successor Escrow Agent.

        13. If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

        14. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

                               SECURITY AGREEMENT

        This Security Agreement is made as of July 22, 1999 between Avanex
Corporation a ("Pledgee"), and Paul Shi-Qi Jiang ("Pledgor").

                                    Recitals

        1. Pledgor has incurred payment obligations (the "Payment Obligations")
to Pledgee set forth in a Promissory Note of even date herewith.

        A. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common Stock of the Pledgee, all options, and similar rights
to acquire such capital stock or interests, and all rights to receive profits or
surplus or other dividends or distributions from the Pledgee to its
shareholders, in each case whether now owned or existing or hereafter acquired
or arising, wherever located, together with all substitutions, replacements,
(the "Shares") to secure performance by Pledgor of the Payment Obligations, all
as more specifically set forth in this Pledge Agreement.

        NOW, THEREFORE, it is agreed as follows:

        (1) Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement), Pledgor, pursuant to the California Commercial Code, hereby pledges
all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number ___, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

        The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Agreement, and
the Pledgeholder shall not encumber or dispose of such Shares except in
accordance with the provisions of this Security Agreement.

        (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

               a. Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

               b. Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.



<PAGE>   19


               c. Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within the meaning of the regulations under Part 207
of Title 12 of the Code of Federal Regulations ("Regulation G"), Pledgor agrees
to cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

        (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

        (4) Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        (5) Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

        (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

               In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

        (7) Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall



                                      -2-
<PAGE>   20

be that number of full Shares which bears the same proportion to the initial
number of Shares pledged hereunder as the payment of principal bears to the
initial full principal amount of the Note.

        (8) Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

        (9) Term. The within pledge of Shares shall continue until the payment
of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

        (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

        (11) Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

        (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

        (13) Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein
shall be deemed to include, for all purposes, the respective designees,
successors, assigns, heirs, executors and administrators.

        (14) Governing Law. This Security Agreement shall be interpreted and
governed under the laws of the State of California.

                               AVANEX CORPORATION

                       RESTRICTED STOCK PURCHASE AGREEMENT

        THIS AGREEMENT is made as of August 4, 1999, by and between Avanex
Corporation, a California corporation (the "COMPANY"), and Simon Xiaofan Cao
(the "PURCHASER").

        The parties agree as follows:

        1. Sale of Stock. The Company hereby agrees to sell to the Purchaser and
the Purchaser hereby agrees to purchase an aggregate of 600,000 shares of the
Company's Common Stock, no par value (the "SHARES") at a price of $0.15 per
share for an aggregate purchase price of $90,000.00.

        2. Payment of Purchase Price. The payment of the purchase price shall be
by by delivery of a promissory note in the form attached hereto as EXHIBIT C,
secured by the shares so purchased pursuant to a Pledge Agreement in the form
attached hereto as EXHIBIT D.

        3. Repurchase Option. In the event of any voluntary or involuntary
termination of the Purchaser's employment by, or services to, the Company for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (as defined below in Section 4),
the Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option, but not the
obligation, for a period of 90 days from such date to repurchase all or any
portion of the Unreleased Shares (as defined below in Section 4) at such time at
the original purchase price per share (the "REPURCHASE PRICE"). The Repurchase
Option shall be exercisable by the Company by written notice to the Purchaser or
the Purchaser's executor (with a copy to the Escrow Agent, as defined below in
Section 6) and shall be exercisable, at the Company's option, (i) by delivery to
the Purchaser or the Purchaser's executor with such notice of a check in the
amount of the purchase price for the Shares being repurchased, or (ii) by
cancellation by the Company of an amount of the Purchaser's indebtedness, if
any, to the Company equal to the purchase price for the Shares being
repurchased, or (iii) by a combination of (i) and (ii) so that the combined
payment and cancellation of indebtedness equals the Repurchase Price times the
number of shares to be repurchased (the "AGGREGATE REPURCHASE PRICE"). Upon
delivery of such notice and the payment of the Aggregate Repurchase Price in any
of the ways described above, the Company shall become the legal and beneficial
owner of the Shares being repurchased and all rights and interests therein or
relating thereto, and the Company shall have the right to retain and transfer to
its own name the number of Shares being repurchased by the Company. The
Repurchase Option set forth in this Section may be assigned by the Company in
whole or in part in its sole and unfettered discretion.

        4. Release of Shares From Repurchase Option.

               (a) The Shares shall vest to Purchaser and be released from the
Company's repurchase option as follows: Provided that Purchaser maintains a
continuous status as a Service Provider of the Company, 25% of the Shares shall
be released from the Company's Repurchase


<PAGE>   2






Option on the one year anniversary of the Vesting Commencement Date and an
additional 1/48th of the Shares shall be released from the Company's Repurchase
Option on the last day of each full calendar month thereafter. Notwithstanding
the foregoing, upon any Change of Control (as herein defined) that number of
Unreleased Shares, if any, which, when aggregated with any Shares previously
released from the Repurchase Option, are required to equal fifty percent (50%)
of the Shares shall be released from the Repurchase Option on the date the event
constituting a Change of Control is consummated. The balance of the Shares
subject to the Repurchase Option shall continue to be released from the
Repurchase Option on the same schedule as existed prior to the Change of
Control. For example, if a Change of Control occurs on a date where 25% of
Purchaser's Shares have been released from the Company's Purchase Option, then
an additional 25% of the Shares shall be released from the Purchase Option
pursuant hereto. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

               (b) "Change of Control" shall mean any of the following: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the shareholders of the Company of more than fifty percent (50%)
of the voting stock of the Company, (ii) a merger or consolidation of the
Company with any other corporation which results in the voting securities of the
Company outstanding immediately prior thereto representing (either by remaining
outstanding or by being converted into voting securities of the surviving entity
or its parent) less than fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity (or
its parent) outstanding immediately after such merger or consolidation, or (iii)
the approval by the shareholders of the Company of a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all the Company's assets.

               (c) Any of the Shares which have not yet been released from the
Company's repurchase option are referred to herein as "Unreleased Shares."

               (d) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's request
(see Section 3).

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Repurchase Option upon the date of such termination.

        For the purposes of this Section 4(e), the following terms referred to
in this Agreement shall have the following meanings:

                      (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.


                                      -2-
<PAGE>   3






                      (ii) Disability. "Disability" shall mean that the
Purchaser has been unable to substantially perform his duties as the result of
his incapacity due to physical or mental illness, and such inability, at least
26 weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the
Purchaser or the Purchaser's legal representative (such agreement as to
acceptability not to be unreasonably withheld).

                      (iii) Involuntary Termination. "Involuntary Termination"
shall mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the relocation of the Purchaser to a facility or a location more than 50
miles from the Purchaser's then present location, without the Purchaser's
express written consent; (vi) any purported termination of the Purchaser by the
Company which is not effected for death or Disability or for Cause, or any
purported termination for which the grounds relied upon are not valid; or (vii)
the failure of the Company to obtain the assumption of this agreement by any
successors contemplated in Section 4(f) below.

               (f) Successors.

                      (i) Company's Successors. Any successor to the Company
(whether direct or indirect and whether by purchase, merger, consolidation,
liquidation or otherwise) to all or substantially all of the Company's business
and/or assets shall assume the obligations under this Section 4 and agree
expressly to perform the obligations under this Section 4 in the same manner and
to the same extent as the Company would be required to perform such obligations
in the absence of a succession. For all purposes under this Section 4, the term
"COMPANY" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this Section
4(f)(i) or which becomes bound by the terms of this Agreement by operation of
law.

                      (ii) Purchaser's Successors. The terms of this Section 4
and all rights of the Purchaser hereunder shall inure to the benefit of, and be
enforceable by, the Purchaser's personal


                                      -3-
<PAGE>   4






or legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees.

        5. Restriction on Transfer.

               (a) Except for the escrow described below in Section 6, none of
the Shares or any beneficial interest therein shall be transferred, encumbered
or otherwise disposed of in any manner until the release of such Shares from the
Repurchase Option in accordance with the provisions of this Agreement.

               (b) Before any Shares may be sold or transferred (including
transfer by operation of law), such Shares shall first be offered to the Company
(the "RIGHT OF FIRST Refusal").

                      (i) Notice. In the event the Purchaser wishes to sell the
Shares, Purchaser shall deliver a notice ("Notice") to the Company stating (A)
his bona fide intention to sell or transfer such Shares, (B) the number of such
Shares to be sold or transferred, (C) the price for which he proposes to sell or
transfer such Shares, and (D) the name of the proposed purchaser or transferee.

                      (ii) Election to Purchase. Within thirty (30) days after
receipt of the Notice, the Company or its assignee may elect to purchase all or
none of the Shares to which the Notice refers, at the price per share specified
in the Notice. The purchase of the Shares in either such event shall occur at a
closing held at the Company's principal office at a mutually agreed upon time
which in no event shall be more than thirty (30) days following the end of the
time period in which the Company had to elect to purchase such Shares.

                      (iii) Sale of Shares by Purchaser. If all of the Shares to
which the Notice refers are not elected to be purchased, as provided in this
Section 5(b), Purchaser may sell the Shares to any person named in the Notice at
the price specified in the Notice or at a higher price, provided that such sale
or transfer is consummated within sixty (60) days of the date of said Notice to
the Company, and provided, further, that any such sale is in accordance with all
the terms and conditions hereof.

                      (iv) Termination of Restrictions. Notwithstanding the
provisions of Section 5(a) above, the Company's Right of First Refusal shall
terminate immediately as to all Shares upon the occurrence of the first to occur
of the following events:

                           (A) the acquisition of the Company by another entity
by means of the merger or consolidation of the Company with or into another
corporation in which the stock-holders of the Company immediately prior to such
merger or consolidation own less than 50% of the voting securities of the
surviving entity,

                           (B) the sale of all or substantially all of the
assets of the Company, or


                                      -4-
<PAGE>   5






                           (C) the date upon which a public market exists for
the Company's capital stock (or any other stock issued to purchasers in exchange
for the Shares purchased under this Agreement). For the purpose of this
Agreement, a "Public Market" shall be deemed to exist if (1) such stock is
listed on a national securities exchange (as that term is used in the Securities
Exchange Act of 1934), or (2) such stock is traded on the over-the-counter
market and prices are published daily on business days in a recognized financial
journal.

                      (v) Assignment. Whenever the Company shall have the right
to purchase Shares under this Section 5, the Company may designate and assign
one or more employees, officers, directors or shareholders of the Company or
other persons or organizations to exercise all of the Company's purchase rights
under this Agreement and purchase all of such Shares; provided that if the fair
market value of the Shares to be purchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the purchase price of the Shares
(determined as described hereinabove) to be purchased, then each such designee
or assignee shall pay the Company cash equal to the difference between the
Repurchase FMV and the purchase price of the Shares which such designee or
assignee shall have the right to purchase.

                      (vi) Exempt Transfers. The provisions of this Section 5
shall not apply to a transfer of any Shares by Purchaser, either during his
lifetime or on death by will or intestacy to his ancestors, descendants or
spouse, or any custodian or trustee for the account of Purchaser or Purchaser's
ancestors, descendants or spouse; provided, in each such case that the
transferee shall receive and hold such Shares subject to all of the provisions
of this Section 5 and there shall be no further transfer of such Shares except
in accordance herewith.

        6. Escrow of Shares. Pursuant to the terms of the Joint Escrow
Instructions attached hereto as EXHIBIT B, the Shares issued under this
Agreement shall be held by the Escrow Agent (as defined in such Joint Escrow
Instructions) along with a stock assignment executed by the Purchaser in blank
in the form attached hereto as EXHIBIT A.

        7. Investment Representations. In connection with the purchase of the
Shares, the Purchaser represents to the Company the following:

               (a) The Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. The
Purchaser is purchasing the Shares for investment for the Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "SECURITIES ACT").

               (b) The Purchaser understands that the Shares have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of the
Purchaser's investment intent as expressed herein. In this connection, the
Purchaser understands that, in the view of the Securities and Exchange
Commission (the "COMMISSION"), the statutory basis for such exemption may not be
present if the Purchaser's representations meant that the Purchaser's present
intention was to hold the Shares for a minimum


                                      -5-
<PAGE>   6






capital gains period under applicable tax statutes, for a deferred sale, for a
market rise, for a sale if the market does not rise, or for a year or any other
fixed period in the future.

               (c) The Purchaser further acknowledges and understands that the
Shares must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. The
Purchaser further acknowledges and understands that the Company is under no
obligation to register the Shares. The Purchaser understands that the
certificate evidencing the Shares will be imprinted with a legend which
prohibits the transfer of the Shares unless they are registered or such
registration is not required in the opinion of counsel satisfactory to the
Company.

        8. Stock Certificate Legends. The share certificate evidencing the
Shares issued hereunder shall be endorsed with the following legends:

               (a) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
        FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
        1933. THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
        REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE
        AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
        TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE
        HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION
        AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

               (b) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED
        ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY
        AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF
        THE COMPANY.

               (c) Any legend required by any applicable state securities laws.

        9. Market Stand-Off Agreement. The Purchaser hereby agrees, if so
requested by the managing underwriters or the Company in connection with the
initial public offering of the Company's Common Stock, that, without the prior
written consent of such managing underwriters, the Purchaser will not offer,
sell, contract to sell, grant any option to purchase, make any short sale or
otherwise dispose of, assign any legal or beneficial interest in or make a
distribution of any capital stock of the Company held by or on behalf of the
Purchaser or beneficially owned by the Purchaser in accordance with the rules
and regulations of the Securities and Exchange Commission for a period of up to
180 days after the date of the final prospectus relating to the Company's
initial public offering.

        10. Adjustment for Stock Split. All references to the number of Shares
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, reverse stock split or stock dividend or
other similar change in the Shares which may be made by the Company after the
date of this Agreement.


                                      -6-

        11. Tax Consequences. The Purchaser has reviewed with the Purchaser's
own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. The Purchaser understands that the Purchaser
(and not the Company) shall be responsible for the Purchaser's own tax liability
that may arise as a result of this investment or the transactions contemplated
by this Agreement. The Purchaser understands that Section 83 of the Internal
Revenue Code of 1986, as amended (the "CODE"), taxes as ordinary income both (i)
the difference between the fair market value of the Shares when the Company
granted the Purchaser the right to purchase the Shares and the fair market value
of the Shares on the date of this Agreement, and (ii) the difference between the
amount paid for the Shares and the fair market value of the Shares as of the
date any restrictions on the Shares lapse. In this context, "restriction"
includes the right of the Company to buy back the Shares pursuant to its
repurchase option. In the event the Company has registered under the Exchange
Act, "restriction" with respect to officers, directors and 10% shareholders also
means the period after the purchase of the Shares during which such officers,
directors and 10% shareholders could be subject to suit under Section 16(b) of
the Exchange Act. The Purchaser understands that the Purchaser may elect to be
taxed at the time the Shares are purchased rather than when and as the Company's
repurchase option or 16(b) period expires by filing an election under Section
83(b) of the Code with the I.R.S. within 30 days from the date of purchase.

               THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

        12. California Corporate Securities Law. THE SALE OF THE SECURITIES
WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE
COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH
SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR
PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT
FROM THE QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA
CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY
CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO
EXEMPT.

        13. General Provisions.

Repurchase Option (as defined in the Agreement), the Company shall give to
Purchaser and you a written notice specifying the number of shares of stock to
be purchased, the purchase price and the time for a closing hereunder at the

        2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate

Company's repurchase option.

        3. Purchaser irrevocably authorizes the Company to deposit with you any

shares held or issued pursuant to the Agreement and not purchased by the Company
or its assignees pursuant to exercise of the Company's repurchase option.

excepting only orders or process of courts of law and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court. In

be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to

                               SECURITY AGREEMENT

        This Security Agreement is made as of August 4, 1999 between Avanex
Corporation a ("Pledgee"), and Simon Xiaofan Cao ("Pledgor").

                                    Recitals

        A. Pledgor has incurred payment obligations (the "Payment Obligations")
to Pledgee set forth in a Promissory Note of even date herewith.

        B. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common Stock of the Pledgee, all options, and similar rights
to acquire such capital stock or interests, and all rights to receive profits or
surplus or other dividends or distributions from the Pledgee to its
shareholders, in each case whether now owned or existing or hereafter acquired
or arising, wherever located, together with all substitutions, replacements,
(the "Shares") to secure performance by Pledgor of the Payment Obligations, all
as more specifically set forth in this Pledge Agreement.

        NOW, THEREFORE, it is agreed as follows:

        (1) Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement), Pledgor, pursuant to the California Commercial Code, hereby pledges
all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number ___, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

        The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Agreement, and
the Pledgeholder shall not encumber or dispose of such Shares except in
accordance with the provisions of this Security Agreement.

        (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

               a. Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

               b. Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.

               c. Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within the meaning of the regulations under Part 207
of Title 12 of the Code of Federal Regulations


<PAGE>   20


("Regulation G"), Pledgor agrees to cooperate with Pledgee in making any
amendments to the Note or providing any additional collateral as may be
necessary to comply with such regulations.

        (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

        (4) Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        (5) Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

        (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

               In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

        (7) Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

        (8) Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

        (9) Term. The within pledge of Shares shall continue until the payment
of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

        (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

        (11) Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

        (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

        (13) Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein
shall be deemed to include, for all purposes, the respective designees,
successors, assigns, heirs, executors and administrators.

        (14) Governing Law. This Security Agreement shall be interpreted and

                               AVANEX CORPORATION

                       RESTRICTED STOCK PURCHASE AGREEMENT


     THIS AGREEMENT is made as of August 4, 1999, by and between Avanex
Corporation, a California corporation (the "COMPANY"), and Peter Maguire (the
"PURCHASER").

     The parties agree as follows:

     1. Sale of Stock. The Company hereby agrees to sell to the Purchaser and
the Purchaser hereby agrees to purchase an aggregate of 550,000 shares of the
Company's Common Stock, no par value (the "SHARES") at a price of $0.15 per
share for an aggregate purchase price of $82,500.00.

     2. Payment of Purchase Price. The payment of the purchase price shall be by
by delivery of a promissory note in the form attached hereto as EXHIBIT C,
secured by the shares so purchased pursuant to a Pledge Agreement in the form
attached hereto as EXHIBIT D.

     3. Repurchase Option. In the event of any voluntary or involuntary
termination of the Purchaser's employment by, or services to, the Company for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (as defined below in Section 4),
the Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option, but not the
obligation, for a period of 90 days from such date to repurchase all or any
portion of the Unreleased Shares (as defined below in Section 4) at such time at
the original purchase price per share (the "REPURCHASE PRICE"). The Repurchase
Option shall be exercisable by the Company by written notice to the Purchaser or
the Purchaser's executor (with a copy to the Escrow Agent, as defined below in
Section 6) and shall be exercisable, at the Company's option, (i) by delivery to
the Purchaser or the Purchaser's executor with such notice of a check in the
amount of the purchase price for the Shares being repurchased, or (ii) by
cancellation by the Company of an amount of the Purchaser's indebtedness, if
any, to the Company equal to the purchase price for the Shares being
repurchased, or (iii) by a combination of (i) and (ii) so that the combined
payment and cancellation of indebtedness equals the Repurchase Price times the
number of shares to be repurchased (the "AGGREGATE REPURCHASE PRICE"). Upon
delivery of such notice and the payment of the Aggregate Repurchase Price in any
of the ways described above, the Company shall become the legal and beneficial
owner of the Shares being repurchased and all rights and interests therein or
relating thereto, and the Company shall have the right to retain and transfer to
its own name the number of Shares being repurchased by the Company. The
Repurchase Option set forth in this Section may be assigned by the Company in
whole or in part in its sole and unfettered discretion.

     4. Release of Shares From Repurchase Option.

          (a) The Shares shall vest to Purchaser and be released from the
Company's repurchase option as follows: Provided that Purchaser maintains a
continuous status as a Service Provider of the Company, 25% of the Shares shall
be released from the Company's Repurchase Option on the one year anniversary of
the Vesting Commencement Date and an additional 1/48th of the Shares shall be
released from the Company's Repurchase Option on the last day of each full

<PAGE>   2

calendar month thereafter. Notwithstanding the foregoing, upon any Change of
Control (as herein defined) that number of Unreleased Shares, if any, which,
when aggregated with any Shares previously released from the Repurchase Option,
are required to equal fifty percent (50%) of the Shares shall be released from
the Repurchase Option on the date the event constituting a Change of Control is
consummated. The balance of the Shares subject to the Repurchase Option shall
continue to be released from the Repurchase Option on the same schedule as
existed prior to the Change of Control. For example, if a Change of Control
occurs on a date where 25% of Purchaser's Shares have been released from the
Company's Purchase Option, then an additional 25% of the Shares shall be
released from the Purchase Option pursuant hereto. If a Change of Control occurs
on a date where more than 50% of Purchaser's Shares have already been released
from the Company's Purchase Option, then no additional Shares shall be released
from the Purchase Option.

          (b) "Change of Control" shall mean any of the following: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the shareholders of the Company of more than fifty percent (50%)
of the voting stock of the Company, (ii) a merger or consolidation of the
Company with any other corporation which results in the voting securities of the
Company outstanding immediately prior thereto representing (either by remaining
outstanding or by being converted into voting securities of the surviving entity
or its parent) less than fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity (or
its parent) outstanding immediately after such merger or consolidation, or (iii)
the approval by the shareholders of the Company of a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all the Company's assets.

          (c) Any of the Shares which have not yet been released from the
Company's repurchase option are referred to herein as "Unreleased Shares."

          (d)  The Shares which have been released from the Company's Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request (see
Section 3).

          (e)  Acceleration Upon Termination of Employment. In addition to the
Shares released from the Company's Repurchase Option pursuant to Section 4(d)
above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Repurchase Option upon the date of such termination.

     For the purposes of this Section 4(e), the following terms referred to in
this Agreement shall have the following meanings:

               (i)  Cause. "Cause" shall mean (i) any act of personal dishonesty
taken by the Purchaser in connection with his responsibilities as an employee
and intended to result in substantial personal enrichment of the Purchaser, (ii)
conviction of a felony that is injurious to the Company, and (iii) a willful act
by the Purchaser which constitutes gross misconduct and which is injurious to
the Company.

               (ii) Disability. "Disability" shall mean that the Purchaser has
been unable to substantially perform his duties as the result of his incapacity
due to physical or mental illness,

                                      -2-
<PAGE>   3
and such inability, at least 26 weeks after its commencement, is determined to
be total and permanent by a physician selected by the Company or its insurers
and acceptable to the Purchaser or the Purchaser's legal representative (such
agreement as to acceptability not to be unreasonably withheld).

               (iii) Involuntary Termination. "Involuntary Termination" shall
mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the relocation of the Purchaser to a facility or a location more than 50
miles from the Purchaser's then present location, without the Purchaser's
express written consent; (vi) any purported termination of the Purchaser by the
Company which is not effected for death or Disability or for Cause, or any
purported termination for which the grounds relied upon are not valid; or (vii)
the failure of the Company to obtain the assumption of this agreement by any
successors contemplated in Section 4(f) below.

          (f)  Successors.

               (i)  Company's Successors. Any successor to the Company (whether
direct or indirect and whether by purchase, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Section 4 and agree expressly to
perform the obligations under this Section 4 in the same manner and to the same
extent as the Company would be required to perform such obligations in the
absence of a succession. For all purposes under this Section 4, the term
"COMPANY" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this Section
4(f)(i) or which becomes bound by the terms of this Agreement by operation of
law.

               (ii) Purchaser's Successors. The terms of this Section 4 and all
rights of the Purchaser hereunder shall inure to the benefit of, and be
enforceable by, the Purchaser's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

                                      -3-

     5.   Restriction on Transfer.

          (a)  Except for the escrow described below in Section 6, none of the
Shares or any beneficial interest therein shall be transferred, encumbered or
otherwise disposed of in any manner until the release of such Shares from the
Repurchase Option in accordance with the provisions of this Agreement.

          (b)  Before any Shares may be sold or transferred (including transfer
by operation of law), such Shares shall first be offered to the Company (the
"RIGHT OF FIRST REFUSAL").

               (i)  Notice. In the event the Purchaser wishes to sell the
Shares, Purchaser shall deliver a notice ("Notice") to the Company stating (A)
his bona fide intention to sell or transfer such Shares, (B) the number of such
Shares to be sold or transferred, (C) the price for which he proposes to sell or
transfer such Shares, and (D) the name of the proposed purchaser or transferee.

               (ii) Election to Purchase. Within thirty (30) days after receipt
of the Notice, the Company or its assignee may elect to purchase all or none of
the Shares to which the Notice refers, at the price per share specified in the
Notice. The purchase of the Shares in either such event shall occur at a closing
held at the Company's principal office at a mutually agreed upon time which in
no event shall be more than thirty (30) days following the end of the time
period in which the Company had to elect to purchase such Shares.

               (iii) Sale of Shares by Purchaser. If all of the Shares to which
the Notice refers are not elected to be purchased, as provided in this Section
5(b), Purchaser may sell the Shares to any person named in the Notice at the
price specified in the Notice or at a higher price, provided that such sale or
transfer is consummated within sixty (60) days of the date of said Notice to the
Company, and provided, further, that any such sale is in accordance with all the
terms and conditions hereof.

               (iv) Termination of Restrictions. Notwithstanding the provisions
of Section 5(a) above, the Company's Right of First Refusal shall terminate
immediately as to all Shares upon the occurrence of the first to occur of the
following events:

                    (A)  the acquisition of the Company by another entity by
means of the merger or consolidation of the Company with or into another
corporation in which the stock-holders of the Company immediately prior to such
merger or consolidation own less than 50% of the voting securities of the
surviving entity,

                    (B)  the sale of all or substantially all of the assets of
the Company, or

                    (C)  the date upon which a public market exists for the
Company's capital stock (or any other stock issued to purchasers in exchange for
the Shares purchased under this Agreement). For the purpose of this Agreement, a
"Public Market" shall be deemed to exist if (1) such stock is listed on a
national securities exchange (as that term is used in the Securities Exchange
Act of 1934), or (2) such stock is traded on the over-the-counter market and
prices are published daily on business days in a recognized financial journal.

                                      -4-
<PAGE>   5

               (v)  Assignment. Whenever the Company shall have the right to
purchase Shares under this Section 5, the Company may designate and assign one
or more employees, officers, directors or shareholders of the Company or other
persons or organizations to exercise all of the Company's purchase rights under
this Agreement and purchase all of such Shares; provided that if the fair market
value of the Shares to be purchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the purchase price of the Shares
(determined as described hereinabove) to be purchased, then each such designee
or assignee shall pay the Company cash equal to the difference between the
Repurchase FMV and the purchase price of the Shares which such designee or
assignee shall have the right to purchase.

               (vi) Exempt Transfers. The provisions of this Section 5 shall not
apply to a transfer of any Shares by Purchaser, either during his lifetime or on
death by will or intestacy to his ancestors, descendants or spouse, or any
custodian or trustee for the account of Purchaser or Purchaser's ancestors,
descendants or spouse; provided, in each such case that the transferee shall
receive and hold such Shares subject to all of the provisions of this Section 5
and there shall be no further transfer of such Shares except in accordance
herewith.

     6. Escrow of Shares. Pursuant to the terms of the Joint Escrow Instructions
attached hereto as EXHIBIT B, the Shares issued under this Agreement shall be
held by the Escrow Agent (as defined in such Joint Escrow Instructions) along
with a stock assignment executed by the Purchaser in blank in the form attached
hereto as EXHIBIT A.

     7. Investment Representations. In connection with the purchase of the
Shares, the Purchaser represents to the Company the following:

        (a)  The Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. The
Purchaser is purchasing the Shares for investment for the Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "SECURITIES ACT").

          (b) The Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of the
Purchaser's investment intent as expressed herein. In this connection, the
Purchaser understands that, in the view of the Securities and Exchange
Commission (the "COMMISSION"), the statutory basis for such exemption may not be
present if the Purchaser's representations meant that the Purchaser's present
intention was to hold the Shares for a minimum capital gains period under
applicable tax statutes, for a deferred sale, for a market rise, for a sale if
the market does not rise, or for a year or any other fixed period in the future.

          (c) The Purchaser further acknowledges and understands that the Shares
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. The
Purchaser further acknowledges and understands that the Company is under no
obligation to register the Shares. The Purchaser understands that the
certificate evidencing the Shares will be imprinted with a legend which
prohibits the transfer of the

                                      -5-
<PAGE>   6

Shares unless they are registered or such registration is not required in the
opinion of counsel satisfactory to the Company.

     8.   Stock Certificate Legends. The share certificate evidencing the Shares
issued hereunder shall be endorsed with the following legends:

          (a) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THESE
SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE AGREEMENT COVERING THE
PURCHASE OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO
COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
CORPORATION.

          (b) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY
IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE
SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

          (c) Any legend required by any applicable state securities laws.

     9.   Market Stand-Off Agreement. The Purchaser hereby agrees, if so
requested by the managing underwriters or the Company in connection with the
initial public offering of the Company's Common Stock, that, without the prior
written consent of such managing underwriters, the Purchaser will not offer,
sell, contract to sell, grant any option to purchase, make any short sale or
otherwise dispose of, assign any legal or beneficial interest in or make a
distribution of any capital stock of the Company held by or on behalf of the
Purchaser or beneficially owned by the Purchaser in accordance with the rules
and regulations of the Securities and Exchange Commission for a period of up to
180 days after the date of the final prospectus relating to the Company's
initial public offering.

     10. Adjustment for Stock Split. All references to the number of Shares and
the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, reverse stock split or stock dividend or
other similar change in the Shares which may be made by the Company after the
date of this Agreement.

     11. Tax Consequences. The Purchaser has reviewed with the Purchaser's own
tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. The Purchaser understands that the Purchaser
(and not the Company) shall be responsible for the Purchaser's own tax liability
that may arise as a result of this investment or the transactions contemplated
by this Agreement. The Purchaser understands that Section 83 of the Internal
Revenue Code of 1986, as amended (the "CODE"), taxes as ordinary income both (i)
the difference between the fair market value of the Shares

                                      -6-
<PAGE>   7

when the Company granted the Purchaser the right to purchase the Shares and the
fair market value of the Shares on the date of this Agreement, and (ii) the
difference between the amount paid for the Shares and the fair market value of
the Shares as of the date any restrictions on the Shares lapse. In this context,
"restriction" includes the right of the Company to buy back the Shares pursuant
to its repurchase option. In the event the Company has registered under the
Exchange Act, "restriction" with respect to officers, directors and 10%
shareholders also means the period after the purchase of the Shares during which
such officers, directors and 10% shareholders could be subject to suit under
Section 16(b) of the Exchange Act. The Purchaser understands that the Purchaser
may elect to be taxed at the time the Shares are purchased rather than when and
as the Company's repurchase option or 16(b) period expires by filing an election
under Section 83(b) of the Code with the I.R.S. within 30 days from the date of
purchase.

     THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE RESPONSIBILITY
AND NOT THE COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION 83(b), EVEN IF
THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON
THE PURCHASER'S BEHALF.

     12. California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH
ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER
OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES
OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO
SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM THE
QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA CORPORATIONS
CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON
SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

     13.  General Provisions.

          (a)  This Agreement shall be governed by the laws of the State of
California. This Agreement represents the entire agreement between the parties
with respect to the purchase of Common Stock by the Purchaser and may only be
modified or amended in writing signed by both parties.

          (b) Any notice, demand or request required or permitted to be given by
either the Company or the Purchaser pursuant to the terms of this Agreement
shall be in writing and shall be deemed given when delivered personally or
deposited in the U.S. mail, First Class with postage prepaid, and addressed to
the parties at the addresses of the parties set forth at the end of this
Agreement or such other address as a party may request by notifying the other in
writing.

          (c) The rights and benefits of the Company under this Agreement shall
be transferable to any one or more persons or entities, and all covenants and
agreements hereunder shall inure to the benefit of, and be enforceable by the
Company's successors and assigns. The rights and obligations of the Purchaser
under this Agreement may only be assigned with the prior written consent of the
Company and any purported transfer otherwise shall be null and void.

                                      -7-
<PAGE>   8

          (d) Either party's failure to enforce any provision or provisions of
this Agreement shall not in any way be construed as a waiver of any such
provision or provisions, nor prevent that party thereafter from enforcing each
and every other provision of this Agreement. The rights granted both parties
herein are cumulative and shall not constitute a waiver of either party's right
to assert all other legal remedies available to it under the circumstances.

          (e) The Purchaser agrees upon request to execute any further documents
or instruments necessary or desirable to carry out the purposes or intent of
this Agreement.

                               SECURITY AGREEMENT

     This Security Agreement is made as of August 4, 1999 between Avanex
Corporation a ("Pledgee"), and Peter Maguire ("Pledgor").

                                    Recitals

     A. Pledgor has incurred payment obligations (the "Payment Obligations") to
Pledgee set forth in a Promissory Note of even date herewith.

     B. Pledgor desires to provide a security interest in all of the Pledgor's
shares of Common Stock of the Pledgee, all options, and similar rights to
acquire such capital stock or interests, and all rights to receive profits or
surplus or other dividends or distributions from the Pledgee to its
shareholders, in each case whether now owned or existing or hereafter acquired
or arising, wherever located, together with all substitutions, replacements,
(the "Shares") to secure performance by Pledgor of the Payment Obligations, all
as more specifically set forth in this Pledge Agreement.

     NOW, THEREFORE, it is agreed as follows:

     (1) Creation and Description of Security Interest. In consideration of the
transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement), Pledgor, pursuant to the California Commercial Code, hereby pledges
all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number __, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

     The pledged stock (together with an executed blank stock assignment for use
in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Agreement, and
the Pledgeholder shall not encumber or dispose of such Shares except in
accordance with the provisions of this Security Agreement.

     (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

          a. Payment of Indebtedness. Pledgor will pay the principal sum of the
Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

          b. Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.

          c. Margin Regulations. In the event that Pledgee's Common Stock is now
or later becomes margin-listed by the Federal Reserve Board and Pledgee is
classified as a "lender" within the meaning of the regulations under Part 207 of
Title 12 of the Code of Federal Regulations

<PAGE>   18

("Regulation G"), Pledgor agrees to cooperate with Pledgee in making any
amendments to the Note or providing any additional collateral as may be
necessary to comply with such regulations.

     (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

     (4) Stock Adjustments. In the event that during the term of the pledge any
stock dividend, reclassification, readjustment or other changes are declared or
made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

     (5) Options and Rights. In the event that, during the term of this pledge,
subscription Options or other rights or options shall be issued in connection
with the pledged Shares, such rights, Options and options shall be the property
of Pledgor and, if exercised by Pledgor, all new stock or other securities so
acquired by Pledgor as it relates to the pledged Shares then held by
Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.


     (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

          a. Payment of principal or interest on the Note shall be delinquent
for a period of 10 days or more; or

          b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

     In the case of an event of Default, as set forth above, Pledgee shall have
the right to accelerate payment of the Note upon notice to Pledgor, and Pledgee
shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

     (7) Release of Collateral. Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

                                      -2-
<PAGE>   19

withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

     (9) Term. The within pledge of Shares shall continue until the payment of
all indebtedness secured hereby, at which time the remaining pledged stock shall
be promptly delivered to Pledgor, subject to the provisions for prior release of
a portion of the Collateral as provided in paragraph 7 above.

     (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

     (11) Pledgeholder Liability. In the absence of willful or gross negligence,
Pledgeholder shall not be liable to any party for any of his acts, or omissions
to act, as Pledgeholder.

     (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

     (13) Successors or Assigns. Pledgor and Pledgee agree that all of the terms
of this Security Agreement shall be binding on their respective successors and
assigns, and that the term "Pledgor" and the term "Pledgee" as used herein shall
be deemed to include, for all purposes, the respective designees, successors,
assigns, heirs, executors and administrators.

        2. Payment of Purchase Price. Purchaser herewith delivers to the Company
the aggregate Exercise Price for the Shares by cash or check.

        3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit B.

        4. Repurchase Option.

               (a) In the event the Purchaser's continuous status as a Service
Provider terminates for any or no reason (including death or Disability), the
Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option for a period
of sixty (60) days from such date to repurchase up to that number of shares
which constitute the Unreleased Shares (as defined in Section 5) at the Exercise
Price per share (the "Repurchase Price") (the "Repurchase Option").

               (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

               (c) Whenever the Company shall have the right to repurchase the
Unreleased Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unreleased Shares. If the Fair Market Value of the
Unreleased Shares to be repurchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of the
Unreleased Shares, then each such designee or assignee shall pay the Company
cash equal to the difference between the Repurchase FMV and the aggregate
Repurchase Price of Unreleased Shares to be purchased.

               (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

        5. Release of Shares From Repurchase Option.

               (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

                         (i) One quarter (1/4) of the Shares shall be released
from the Repurchase Option on August 2, 2000; and

                         (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

               (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

               (c) The Shares which have been released from the Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request (see
Section 7).

               (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

        For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:

                         (i) Any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) is or
becomes the "beneficial owner" (as defined in Rule 13d-3 under said Act),
directly or indirectly, of securities of the Company representing 50% or more of
the total voting power represented by the Company's then outstanding voting
securities other than in a private financing transaction approved by the Board
of Directors;

                         (ii) the direct or indirect sale or exchange by the
shareholders of the Company of all or substantially all of the stock of the
Company;



                                       3
<PAGE>   4

                         (iii) a merger or consolidation in which the Company is
a party and in which the shareholders of the Company before such merger or
consolidation do not retain, directly or indirectly, at a least majority of the
beneficial interest in the voting stock of the Company after such transaction;
or

                         (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

        For the purposes of this Section 5(e), the following terms referred to
in this Agreement shall have the following meanings:

                         (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

                         (ii) Disability. "Disability" shall mean that the
Purchaser has been unable to substantially perform his duties as the result of
his incapacity due to physical or mental illness, and such inability, at least
26 weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the
Purchaser or the Purchaser's legal representative (such agreement as to
acceptability not to be unreasonably withheld).

                         (iii) Involuntary Termination. "Involuntary
Termination" shall mean (i) without the Purchaser's express written consent, the
significant reduction of the Purchaser's duties or responsibilities relative to
the Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the



                                       4
<PAGE>   5

relocation of the Purchaser to a facility or a location more than 50 miles from
the Purchaser's then present location, without the Purchaser's express written
consent; (vi) any purported termination of the Purchaser by the Company which is
not effected for death or Disability or for Cause, or any purported termination
for which the grounds relied upon are not valid; or (vii) the failure of the
Company to obtain the assumption of this agreement by any successors
contemplated in Section 4(f) below.

               (f) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's
request.

        6. Restriction on Transfer. Except for the escrow described in 7 or
transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

        7. Escrow of Shares.

               (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

               (b) The Escrow Holder shall not be liable for any act it may do
or omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise of its judgment.

               (c) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

               (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

               (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time



                                       5
<PAGE>   6

during the term of the Company's Repurchase Option, there is (i) any stock
dividend, stock split or other change in the Shares, or (ii) any merger or sale
of all or substantially all of the assets or other acquisition of the Company,
any and all new, substituted or additional securities to which the Purchaser is
entitled by reason of the Purchaser's ownership of the Shares shall be
immediately subject to this escrow, deposited with the Escrow Holder and
included thereafter as "Shares" for purposes of this Agreement and the Company's
Repurchase Option.

        8. Company's Right of First Refusal. Before any Shares held by Purchaser
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

               (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

               (b) Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

               (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.

               (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or (iii) by any combination thereof within thirty (30) days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

               (e) Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided



                                       6
<PAGE>   7

further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, a new Notice shall be
given to the Company, and the Company and/or its assignees shall again be
offered the Right of First Refusal before any Shares held by the Holder may be
sold or otherwise transferred.

               (f) Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

               (g) Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the date of the first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the 1933 Act.

        9. Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

               (a) Purchaser understands and agrees that the Company shall cause
the legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
               SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
               UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL
               SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE
               OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
               RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A
               REPURCHASE OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET
               FORTH IN THE RESTRICTED STOCK PURCHASE AGREEMENT



                                       7
<PAGE>   8

               BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A
               COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE
               ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND
               REPURCHASE OPTION ARE BINDING ON TRANSFEREES OF THESE SHARES.

               (b) Stop-Transfer Notices. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

        10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

        11. Tax Consequences. Set forth below is a brief summary as of the date
of grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

               (a) Exercise of Stock Purchase Right. Generally, no income will
be recognized by Purchaser in connection with the exercise of the stock
purchaser right for shares subject to the Repurchase Option, unless an election
under Section 83(b) of the Code is filed with the Internal Revenue Service
within 30 days of the date of exercise of the right to purchase stock. The form
for making this election is attached as Exhibit A-4 hereto. Otherwise, as the
Company's repurchase right lapses, Purchaser will recognize compensation income
in an amount equal to the difference between the Fair Market Value of the stock
at the time the Company's repurchase right lapses and the amount paid for the
stock, if any (the "Spread"). If Purchaser is an Employee or former Employee,
the Spread will be subject to tax withholding by the Company, and the Company
will be entitled to a tax



                                       8
<PAGE>   9

deduction in the amount at the time the Purchaser recognizes ordinary income
with respect to a Stock Purchase Right.

               (b) Disposition of Shares. Upon disposition of the Shares, any
gain or loss is treated as capital gain or loss. If the Shares are held for at
least one year, any gain realized on disposition of the shares will be treated
as long-term capital gain for federal income tax purposes. Long-term capital
gains are grouped and netted by holding periods. Net capital gains on assets
held for more than 12 months is capped at 20%. Capital losses are allowed in
full against capital gains, and up to $3,000 against other income.

        THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

        12. No Guarantee of Continued Service. PURCHASER ACKNOWLEDGES AND AGREES
THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO
4 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS SERVICE PROVIDER AT THE WILL OF
THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES HEREUNDER).
PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE PURCHASER'S
RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

        13. Notices. Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

        Any notice to the Escrow Holder shall be sent to the Company's address
with a copy to the other party not sending the notice.

        14. No Waiver. Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor prevent that party from thereafter
enforcing each and every other provision of this Agreement. The rights granted
both parties herein are cumulative and shall not constitute a waiver of either
party's right to assert all other legal remedies available to it under the
circumstances.

Corporate Secretary
Avanex Corporation

Fremont, CA 94538

Dear Sirs:

        As Escrow Agent for both Avanex Corporation, a California corporation
(the "Company"), and the undersigned purchaser of stock of the Company (the
"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

        1. In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the Company's
repurchase option set forth in the Agreement (the "Repurchase Option"), the
Company shall give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Company. Purchaser and the
Company hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

        2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, or some combination thereof) for the number of shares of stock
being purchased pursuant to the exercise of the Company's Repurchase Option.

        3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky
authority of any required applications for consent to, or notice of transfer of,
the securities. Subject to the provisions of this paragraph 3, Purchaser shall
exercise all rights and privileges of a shareholder of the Company while the
stock is held by you.



                                       2

        4. Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's Repurchase Option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's Repurchase Option.
Within ninety (90) days after cessation of Purchaser's continuous employment by
or services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's Repurchase
Option.

        5. If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of the same to Purchaser and shall be discharged of all
further obligations hereunder.

        6. Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

        7. You shall be obligated only for the performance of such duties as are
specifically set forth herein and may rely and shall be protected in relying or

shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith,
and any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

        8. You are hereby expressly authorized to disregard any and all warnings
given by any of the parties hereto or by any other person or corporation,
excepting only orders or process of courts of law and are hereby expressly
authorized to comply with and obey orders, judgments or decrees of any court. In
case you obey or comply with any such order, judgment or decree, you shall not
be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.

        12. Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be an officer or agent of the Company or if you shall resign
by written notice to each party. In the event of any such termination, the
Company shall appoint a successor Escrow Agent.

        13. If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

        15. Any notice required or permitted hereunder shall be given in writing
and shall be deemed effectively given upon personal delivery or upon deposit in

                       INVESTMENT REPRESENTATION STATEMENT

        PURCHASER:    JAMES L. PICKERING III

        COMPANY:      AVANEX CORPORATION

        SECURITY:     COMMON STOCK

        AMOUNT:       175,920

        DATE:         OCTOBER 1, 1999

        In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

        (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

        (b) reach an informed and knowledgeable decision to acquire the
Securities. Purchaser is acquiring these Securities for investment for
Purchaser's own account only and not with a view to, or for resale in connection
with, any "distribution" thereof within the meaning of the Securities Act of
1933, as amended (the "Securities Act").

        (c) Purchaser acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Purchaser's investment intent as expressed herein. In this connection,
Purchaser understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Purchaser's representation was predicated solely upon a present intention to
hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one (1) year or any other
fixed period in the future. Purchaser further understands that the Securities
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
further acknowledges and understands that the Company is under no obligation to
register the Securities. Purchaser understands that the certificate evidencing
the Securities will be imprinted with a legend which prohibits the transfer of
the Securities unless they are registered or such registration is not required
in the opinion of counsel satisfactory to the Company, a legend prohibiting
their transfer without the consent of the Commissioner of Corporations of the
State of California and any other legend required under applicable state
securities laws.

        (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities"



                                       8
<PAGE>   20

acquired, directly or indirectly from the issuer thereof, in a non-public
offering subject to the satisfaction of certain conditions. Rule 701 provides
that if the issuer qualifies under Rule 701 at the time of the grant of the
Stock Purchase Right to the Purchaser, the exercise will be exempt from
registration under the Securities Act. In the event the Company becomes subject
to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market
stand-off agreement may require) the Securities exempt under Rule 701 may be
resold, subject to the satisfaction of certain of the conditions specified by
Rule 144, including: (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and,
in the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of Securities being sold during any three (3)
month period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (e) Purchaser further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

<PAGE>   24

                               SECURITY AGREEMENT

               This Security Agreement is made as of October 1, 1999 between
Avanex Corporation ("Pledgee"), and James L. Pickering III ("Pledgor").

                                    Recitals

               A. Pledgor has incurred payment obligations (the "Payment
Obligations") to Pledgee setforth in a Promissory Note of even date herewith.

               B. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common

        Stock of the Pledgee, all options, and similar rights to acquire such
capital stock or interests, and all rights to receive profits or surplus or
other dividends or distributions from the Pledgee to its shareholders, in each
case whether now owned or existing or hereafter acquired or arising, wherever
located, together with all substitutions, replacements, (the "Shares") to secure
performance by Pledgor of the Payment Obligations, all as more specifically set
forth in this Pledge Agreement.

               NOW, THEREFORE, it is agreed as follows:

               (1) Creation and Description of Security Interest. In
consideration of the transfer of the Shares to Pledgor under the Stock Purchase
Agreement (the "Agreement), Pledgor, pursuant to the California Commercial Code,
hereby pledges all of such Shares (herein sometimes referred to as the
"Collateral") represented by certificate number __, duly endorsed in blank or
with executed stock powers, and herewith delivers said certificate to the
Secretary of Pledgee ("Pledgeholder"), who shall hold said certificate subject
to the terms and conditions of this Security Agreement.

               The pledged stock (together with an executed blank stock
assignment for use in transferring all or a portion of the Shares to Pledgee if,
as and when required pursuant to this Security Agreement) shall be held by the
Pledgeholder as security for the repayment of the Note, and any extensions or
renewals thereof, to be executed by Pledgor pursuant to the terms of the
Agreement, and the Pledgeholder shall not encumber or dispose of such Shares
except in accordance with the provisions of this Security Agreement.

               (2) Pledgor's Representations and Covenants. To induce Pledgee to
enter into this Security Agreement, Pledgor represents and covenants to Pledgee,
its successors and assigns, as follows:

               (a) Payment of Indebtedness. Pledgor will pay the principal sum
               of the Note secured hereby, together with interest thereon, at
               the time and in the manner provided in the Note.

               (b) Encumbrances. The Shares are free of all other encumbrances,
               defenses and liens, and Pledgor will not further encumber the
               Shares without the prior written consent of Pledgee.

               (c) Margin Regulations. In the event that Pledgee's Common Stock
               is now or later becomes margin-listed by the Federal Reserve
               Board and Pledgee is classified as a "lender" within the meaning
               of the regulations under Part 207 of Title 12 of the Code of
               Federal Regulations ("Regulation G"), Pledgor agrees to cooperate
               with Pledgee in making any amendments to the Note or providing
               any additional collateral as may be necessary to comply with such
               regulations.

               (3) Voting Rights. During the term of this pledge and so long as
all payments of principal and interest are made as they become due under the
terms of the Note, Pledgor shall have the right to vote all of the Shares
pledged hereunder.

               (4) Stock Adjustments. In the event that during the term of the
pledge any stock dividend, reclassification, readjustment or other changes are
declared or made in the capital structure of Pledgee, all new, substituted and
additional shares or other securities issued by reason of any such change shall
be delivered to and held by the Pledgee under the terms of this Security
Agreement in the same manner as the Shares originally pledged hereunder. In the
event of substitution of such securities, Pledgor, Pledgee and Pledgeholder
shall cooperate and execute such documents as are reasonable so as to provide
for the substitution of such Collateral and, upon such substitution, references
to "Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

               (5) Options and Rights. In the event that, during the term of
this pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

               (6) Default. Pledgor shall be deemed to be in default of the Note
and of this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

               In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

               (7) Release of Collateral. Subject to any applicable contrary
rules under Regulation G, there shall be released from this pledge a portion of
the pledged Shares held by Pledgeholder hereunder upon payments of the principal
of the Note. The number of the pledged Shares which shall be released shall be
that number of full Shares which bears the same proportion to the initial number
of Shares pledged hereunder as the payment of principal bears to the initial
full principal amount of the Note.

               (8) Withdrawal or Substitution of Collateral. Pledgor shall not
sell, withdraw, pledge, substitute or otherwise dispose of all or any part of
the Collateral without the prior written consent of Pledgee.

               (9) Term. The within pledge of Shares shall continue until the
payment of all indebtedness secured hereby, at which time the remaining pledged
stock shall be promptly delivered to Pledgor, subject to the provisions for
prior release of a portion of the Collateral as provided in paragraph 7 above.

               (10) Insolvency. Pledgor agrees that if a bankruptcy or
insolvency proceeding is instituted by or against it, or if a receiver is
appointed for the property of Pledgor, or if Pledgor makes an assignment for the
benefit of creditors, the entire amount unpaid on the Note shall become
immediately due and payable, and Pledgee may proceed as provided in the case of
default.

               (11) Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

               (12) Invalidity of Particular Provisions. Pledgor and Pledgee
agree that the enforceability or invalidity of any provision or provisions of
this Security Agreement shall not render any other provision or provisions
herein contained unenforceable or invalid.

     Expiration Date                    January 7, 2000

     YOU MUST EXERCISE THIS STOCK PURCHASE RIGHT BEFORE THE EXPIRATION DATE OR
IT WILL TERMINATE AND YOU WILL HAVE NO FURTHER RIGHT TO PURCHASE THE SHARES.

Non-Transferability of Stock Purchase Right.

     This Stock Purchase Right may not be transferred in any manner otherwise
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Optionee only by Optionee. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

II.  AGREEMENT

     1. Sale of Stock. The Company hereby agrees to sell to the individual named
in the Notice of Grant of Stock Purchase Right (the "Purchaser"), and the
Purchaser hereby agrees to purchase the number of Shares set forth in the Notice
of Grant of Stock Purchase Right, at the exercise price per share set forth in
the Notice of Grant of Stock Purchase Right (the "Exercise
<PAGE>   2
Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to 14(c) of the Plan, in the event of
a conflict between the terms and conditions of the Plan and this Agreement, the
terms and conditions of the Plan shall prevail.

     2. Payment of Purchase Price. Purchaser herewith delivers to the Company
the aggregate Exercise Price for the Shares by cash or check or promissory note
in the form of Exhibit C secured by the shares pursuant to a Security Agreement
in the form of Exhibit D.

     3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit B.

     4. Repurchase Option.

          (a) In the event the Purchaser's continuous status as a Service
Provider terminates for any or no reason (including death or Disability), the
Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option for a period
of ninety (90) days from such date to repurchase up to that number of shares
which constitute the Unreleased Shares (as defined in Section 5) at the Exercise
Price per share (the "Repurchase Price") (the "Repurchase Option").

          (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

          (c) Whenever the Company shall have the right to repurchase the
Unreleased Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unreleased Shares. If the Fair Market Value of the
Unreleased Shares to be repurchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of the
Unreleased Shares, then each such designee or assignee shall pay the Company
cash equal to the difference between the Repurchase FMV and the aggregate
Repurchase Price of Unreleased Shares to be purchased.

                                       2
<PAGE>   3

          (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

     5. Release of Shares From Repurchase Option.

          (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

               (i) One quarter (1/4) of the Shares shall be released from the
Repurchase Option on October 9, 2000; and

               (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

          (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

          (c) The Shares which have been released from the Repurchase Option
shall be delivered to the Purchaser at the Purchaser's request (see Section 7).

          (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

     For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:

               (i) Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or

                                       3
<PAGE>   4

more of the total voting power represented by the Company's then outstanding
voting securities other than in a private financing transaction approved by the
Board of Directors;

               (ii) the direct or indirect sale or exchange by the shareholders
of the Company of all or substantially all of the stock of the Company;

               (iii) a merger or consolidation in which the Company is a party
and in which the shareholders of the Company before such merger or consolidation
do not retain, directly or indirectly, at a least majority of the beneficial
interest in the voting stock of the Company after such transaction; or

               (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

          (e) Acceleration Upon Termination of Employment. In addition to the
Shares released from the Company's Repurchase Option pursuant to Section 4(d)
above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

     For the purposes of this Section 5(e), the following terms referred to in
this Agreement shall have the following meanings:

               (i) Cause. "Cause" shall mean (i) any act of personal dishonesty
taken by the Purchaser in connection with his responsibilities as an employee
and intended to result in substantial personal enrichment of the Purchaser, (ii)
conviction of a felony that is injurious to the Company, and (iii) a willful act
by the Purchaser which constitutes gross misconduct and which is injurious to
the Company.

               (ii) Disability. "Disability" shall mean that the Purchaser has
been unable to substantially perform his duties as the result of his incapacity
due to physical or mental illness, and such inability, at least 26 weeks after
its commencement, is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the Purchaser or the
Purchaser's legal representative (such agreement as to acceptability not to be
unreasonably withheld).

               (iii) Involuntary Termination. "Involuntary Termination" shall
mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available

                                       4
<PAGE>   5
to the Purchaser immediately prior to such reduction without the Purchaser's
express written consent, a material reduction by the Company in the base
compensation of the Purchaser as in effect immediately prior to such reduction,
or the ineligibility of the Purchaser to continue to participate in any
long-term incentive plan of the Company; (iv) a material reduction by the
Company in the kind or level of employee benefits to which the Purchaser is
entitled immediately prior to such reduction with the result that the
Purchaser's overall benefits package is significantly reduced; (v) the
relocation of the Purchaser to a facility or a location more than 50 miles from
the Purchaser's then present location, without the Purchaser's express written
consent; (vi) any purported termination of the Purchaser by the Company which is
not effected for death or Disability or for Cause, or any purported termination
for which the grounds relied upon are not valid; or (vii) the failure of the
Company to obtain the assumption of this agreement by any successors
contemplated in Section 4(f) below.

          (f) The Shares which have been released from the Company's Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request.

     6. Restriction on Transfer. Except for the escrow described in Section 7 or
transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

     7. Escrow of Shares.

          (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

          (b) The Escrow Holder shall not be liable for any act it may do or
omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise of its judgment and the Company shall
hold Escrow Holder harmless from any and all such liability, including attorneys
fees and other expenses of defending against the assertion of any such claim.

          (c) If the Company or any assignee exercises its Repurchase Option
hereunder, the Escrow Holder, upon receipt of written notice of such option
exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

                                       5
<PAGE>   6

          (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

          (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Company's Repurchase Option.

     8. Company's Right of First Refusal. Before any Shares held by Purchaser or
any transferee (either being sometimes referred to herein as the "Holder") may
be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

          (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

          (b) Exercise of Right of First Refusal. At any time within thirty (30)
days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

          (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.

          (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee,

                                       6
<PAGE>   7

to the assignee), or (iii) by any combination thereof within thirty (30) days
after receipt of the Notice or in the manner and at the times set forth in the
Notice.

          (e) Holder's Right to Transfer. If all of the Shares proposed in the
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section, then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section shall continue to apply to
the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a
new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

          (f) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Purchaser's lifetime or on the Purchaser's death by will or
intestacy to the Purchaser's immediate family or a trust for the benefit of the
Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

          (g) Termination of Right of First Refusal. The Right of First Refusal
shall terminate as to any Shares upon the date of the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
1933 Act.

     9.   Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

          (a) Purchaser understands and agrees that the Company shall cause the
legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
          OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
          REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO
          THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER,


                                       7
<PAGE>   8

          PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

          THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A REPURCHASE
          OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE
          RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE ISSUER AND THE
          ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT
          THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT
          OF FIRST REFUSAL AND REPURCHASE OPTION ARE BINDING ON TRANSFEREES OF
          THESE SHARES.

          (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

     10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

     11. Tax Consequences. Set forth below is a brief summary as of the date of
grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

          (a) Exercise of Stock Purchase Right. Generally, no income will be
recognized by Purchaser in connection with the exercise of the stock purchaser
right for shares subject to the Repurchase Option, unless an election under
Section 83(b) of the Code is filed with the Internal

                                       8
<PAGE>   9

Revenue Service within 30 days of the date of exercise of the right to purchase
stock. The form for making this election is attached as Exhibit A-4 hereto.
Otherwise, as the Company's repurchase right lapses, Purchaser will recognize
compensation income in an amount equal to the difference between the Fair Market
Value of the stock at the time the Company's repurchase right lapses and the
amount paid for the stock, if any (the "Spread"). If Purchaser is an Employee or
former Employee, the Spread will be subject to tax withholding by the Company,
and the Company will be entitled to a tax deduction in the amount at the time
the Purchaser recognizes ordinary income with respect to a Stock Purchase Right.

          (b) Disposition of Shares. Upon disposition of the Shares, any gain or
loss is treated as capital gain or loss. If the Shares are held for at least one
year, any gain realized on disposition of the shares will be treated as
long-term capital gain for federal income tax purposes. Long-term capital gains
are grouped and netted by holding periods. Net capital gains on assets held for
more than 12 months is capped at 20%. Capital losses are allowed in full against
capital gains, and up to $3,000 against other income.

     THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE RESPONSIBILITY
AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF
THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON
THE PURCHASER'S BEHALF.

     12. No Guarantee of Continued Service. PURCHASER ACKNOWLEDGES AND AGREES
THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO
SECTION 12 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS SERVICE PROVIDER AT
THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES
HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
PURCHASER'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.

     13. Notices. Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

     Any notice to the Escrow Holder shall be sent to the Company's address with
a copy to the other party not sending the notice.

     14. No Waiver. Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor

                                       9
<PAGE>   10

prevent that party from thereafter enforcing each and every other provision of
this Agreement. The rights granted both parties herein are cumulative and shall
not constitute a waiver of either party's right to assert all other legal
remedies available to it under the circumstances.

     15. Successors and Assigns. The Company may assign any of its rights under
this Agreement to single or multiple assignees, and this Agreement shall inure
to the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer herein set forth, this Agreement shall be binding upon
Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     16. Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

     17. Governing Law; Severability. This Agreement is governed by the internal
substantive laws but not the choice of law rules, of California.

     18. Entire Agreement. The Plan is incorporated herein by reference. This
Agreement (including the exhibits referenced herein), the Plan, and the
Investment Representation Statement constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Purchaser with
respect to the subject matter hereof, and may not be modified adversely to the
Purchaser's interest except by means of a writing signed by the Company and
Purchaser.

     By Purchaser's signature below, Purchaser represents that he or she is
familiar with the terms and provisions of the Plan, and hereby accepts this
Agreement subject to all of the terms and provisions thereof. Purchaser has
reviewed the Plan and this Agreement in their entirety, has had an opportunity
to obtain the advice of counsel prior to executing this Agreement and fully
understands all provisions of this Agreement. Purchaser agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Agreement.

delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

     1. In the event the Company and/or any assignee of the Company (referred to

repurchase option set forth in the Agreement (the "Repurchase Option"), the
Company shall give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Company. Purchaser and the
Company hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

     2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate

     3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any

corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

     9. You shall not be liable in any respect on account of the identity,
authorities or rights of the parties executing or delivering or purporting to

parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

                       INVESTMENT REPRESENTATION STATEMENT


     PURCHASER:   MARGARET QUINN

     COMPANY:     AVANEX CORPORATION

     SECURITY:    COMMON STOCK

     AMOUNT:      90,000

     DATE:        OCTOBER 8, 1999

     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

     (b) reach an informed and knowledgeable decision to acquire the Securities.
Purchaser is acquiring these Securities for investment for Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "Securities Act").

     (c) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein. In this connection, Purchaser understands
that, in the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Purchaser's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one (1) year or any other fixed period in the future. Purchaser
further understands that the Securities must be held indefinitely unless they
are subsequently registered under the Securities Act or an exemption from such
registration is available. Purchaser further acknowledges and understands that
the Company is under no obligation to register the Securities.

     (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Stock Purchase Right to the Purchaser, the
exercise will be exempt from registration under the Securities Act. In the event
the Company becomes subject to the reporting requirements of Section 13 or 15(d)
of the Securities Exchange Act of 1934, ninety (90) days

<PAGE>   20

thereafter (or such longer period as any market stand-off agreement may require)
the Securities exempt under Rule 701 may be resold, subject to the satisfaction
of certain of the conditions specified by Rule 144, including: (1) the resale
being made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the
availability of certain public information about the Company, (3) the amount of
Securities being sold during any three (3) month period not exceeding the
limitations specified in Rule 144(e), and (4) the timely filing of a Form 144,
if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                               SECURITY AGREEMENT

     This Security Agreement is made as of October 8, 1999 between Avanex
Corporation ("Pledgee"), Margaret Quinn ("Pledgor") and the Secretary of Pledgee
as "Pledgeholder."

                                    Recitals

     A. Pledgor has incurred payment obligations (the "Payment Obligations") to
Pledgee set forth in a Promissory Note of even date herewith.

     B. Pledgor desires to provide a security interest in all of the Pledgor's
shares of Common

     Stock of the Pledgee, all options, and similar rights to acquire such
capital stock or interests, and all rights to receive profits or surplus or
other dividends or distributions from the Pledgee to its shareholders, in each
case whether now owned or existing or hereafter acquired or arising, wherever
located, together with all substitutions, replacements, (the "Shares") to secure
performance by Pledgor of the Payment Obligations, all as more specifically set
forth in this Pledge Agreement.

     NOW, THEREFORE, it is agreed as follows:

     (1) Creation and Description of Security Interest. In consideration of the
transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement), Pledgor, pursuant to the California Commercial Code, hereby pledges
all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number __, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

     The pledged stock (together with an executed blank stock assignment for use
in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Agreement, and
the Pledgeholder shall not encumber or dispose of such Shares except in
accordance with the provisions of this Security Agreement. (2)

<PAGE>   22

     (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

          (a) Payment of Indebtedness. Pledgor will pay the principal sum of the
Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

          (b) Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.

          (c) Margin Regulations. In the event that Pledgee's Common Stock is
now or later becomes margin-listed by the Federal Reserve Board and Pledgee is
classified as a "lender" within the meaning of the regulations under Part 207 of
Title 12 of the Code of Federal Regulations ("Regulation G"), Pledgor agrees to
cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

     (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

     (4) Stock Adjustments. In the event that during the term of the pledge any
stock dividend, reclassification, readjustment or other changes are declared or
made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

     (5) Options and Rights. In the event that, during the term of this pledge,
subscription Options or other rights or options shall be issued in connection
with the pledged Shares, such rights, Options and options shall be the property
of Pledgor and, if exercised by Pledgor, all new stock or other securities so
acquired by Pledgor as it relates to the pledged Shares then held by
Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

                                      -2-
<PAGE>   23

     (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

          a. Payment of principal or interest on the Note shall be delinquent
for a period of 10 days or more; or

          b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

          In the case of an event of Default, as set forth above, Pledgee shall
have the right to accelerate payment of the Note upon notice to Pledgor, and
Pledgee shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

     (7) Release of Collateral. Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

     (8) Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

     (9) Term. The within pledge of Shares shall continue until the payment of
all indebtedness secured hereby, at which time the remaining pledged stock shall
be promptly delivered to Pledgor, subject to the provisions for prior release of
a portion of the Collateral as provided in paragraph 7 above.

     (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

     (11) Pledgeholder Liability. In the absence of willful or gross negligence,
Pledgeholder shall not be liable to any party for any of his acts, or omissions
to act, as Pledgeholder.

     (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

     (13) Successors or Assigns. Pledgor and Pledgee agree that all of the terms
of this Security Agreement shall be binding on their respective successors and
assigns, and that the term "Pledgor"

                                      -3-
<PAGE>   24

purposes, the respective designees, successors, assigns, heirs, executors and
administrators.

governed under the laws of the State of California.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of

                               AVANEX CORPORATION

                       RESTRICTED STOCK PURCHASE AGREEMENT

        THIS AGREEMENT is made as of October 12, 1999, by and between Avanex
Corporation, a California corporation (the "COMPANY"), and Simon Xiaofan Cao
(the "PURCHASER").

        The parties agree as follows:

        1. Sale of Stock. The Company hereby agrees to sell to the Purchaser and
the Purchaser hereby agrees to purchase an aggregate of 680,484 shares of the
Company's Common Stock, no par value (the "SHARES") at a price of $0.58 per
share for an aggregate purchase price of $394,680.72.

        2. Payment of Purchase Price. The payment of the purchase price shall be
by delivery of a promissory note in the form attached hereto as EXHIBIT C,
secured by the shares so purchased pursuant to a Pledge Agreement in the form
attached hereto as EXHIBIT D.

        3. Repurchase Option. In the event of any voluntary or involuntary
termination of the Purchaser's employment by, or services to, the Company for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (as defined below in Section 4),
the Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option, but not the
obligation, for a period of 90 days from such date to repurchase all or any
portion of the Unreleased Shares (as defined below in Section 4) at such time at
the original purchase price per share (the "REPURCHASE PRICE"). The Repurchase
Option shall be exercisable by the Company by written notice to the Purchaser or
the Purchaser's executor (with a copy to the Escrow Agent, as defined below in
Section 6) and shall be exercisable, at the Company's option, (i) by delivery to
the Purchaser or the Purchaser's executor with such notice of a check in the
amount of the purchase price for the Shares being repurchased, or (ii) by
cancellation by the Company of an amount of the Purchaser's indebtedness, if
any, to the Company equal to the purchase price for the Shares being
repurchased, or (iii) by a combination of (i) and (ii) so that the combined
payment and cancellation of indebtedness equals the Repurchase Price times the
number of shares to be repurchased (the "AGGREGATE REPURCHASE PRICE"). Upon
delivery of such notice and the payment of the Aggregate Repurchase Price in any
of the ways described above, the Company shall become the legal and beneficial
owner of the Shares being repurchased and all rights and interests therein or
relating thereto, and the Company shall have the right to retain and transfer to
its own name the number of Shares being repurchased by the Company. The
Repurchase Option set forth in this Section may be assigned by the Company in
whole or in part in its sole and unfettered discretion.

        4. Release of Shares From Repurchase Option.

               (a) The Shares shall vest to Purchaser and be released from the
Company's repurchase option as follows: Provided that Purchaser maintains a
continuous status as a Service Provider of the Company, 25% of the Shares shall
be released from the Company's Repurchase Option on October 8, 2000 and an
additional 1/48th of the Shares shall be released from the Company's Repurchase
Option on the last day of each full calendar month thereafter.



<PAGE>   2

Notwithstanding the foregoing, upon any Change of Control (as herein defined)
that number of Unreleased Shares, if any, which, when aggregated with any Shares
previously released from the Repurchase Option, are required to equal fifty
percent (50%) of the Shares shall be released from the Repurchase Option on the
date the event constituting a Change of Control is consummated. The balance of
the Shares subject to the Repurchase Option shall continue to be released from
the Repurchase Option on the same schedule as existed prior to the Change of
Control. For example, if a Change of Control occurs on a date where 25% of
Purchaser's Shares have been released from the Company's Purchase Option, then
an additional 25% of the Shares shall be released from the Purchase Option
pursuant hereto. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

               (b) "Change of Control" shall mean any of the following: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the shareholders of the Company of more than fifty percent (50%)
of the voting stock of the Company, (ii) a merger or consolidation of the
Company with any other corporation which results in the voting securities of the
Company outstanding immediately prior thereto representing (either by remaining
outstanding or by being converted into voting securities of the surviving entity
or its parent) less than fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity (or
its parent) outstanding immediately after such merger or consolidation, or (iii)
the approval by the shareholders of the Company of a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all the Company's assets.

               (c) Any of the Shares which have not yet been released from the
Company's repurchase option are referred to herein as "Unreleased Shares."

               (d) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's request
(see Section 3).

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Repurchase Option upon the date of such termination.

        For the purposes of this Section 4(e), the following terms referred to
in this Agreement shall have the following meanings:

                    (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

                    (ii) Disability. "Disability" shall mean that the Purchaser
has been unable to substantially perform his duties as the result of his
incapacity due to physical or mental illness,



                                      -2-
<PAGE>   3

and such inability, at least 26 weeks after its commencement, is determined to
be total and permanent by a physician selected by the Company or its insurers
and acceptable to the Purchaser or the Purchaser's legal representative (such
agreement as to acceptability not to be unreasonably withheld).

                    (iii) Involuntary Termination. "Involuntary Termination"
shall mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of the Company being acquired and made part of a larger entity
(as, for example, when the Chief Financial Officer of Company remains as such
following a Change of Control and is not made the Chief Financial Officer of the
acquiring corporation) shall not constitute an "Involuntary Termination"; (ii)
without the Purchaser's express written consent, a substantial reduction,
without good business reasons, of the facilities and perquisites (including
office space and location) available to the Purchaser immediately prior to such
reduction; (iii) without the Purchaser's express written consent, a material
reduction by the Company in the base compensation of the Purchaser as in effect
immediately prior to such reduction, or the ineligibility of the Purchaser to
continue to participate in any long-term incentive plan of the Company; (iv) a
material reduction by the Company in the kind or level of employee benefits to
which the Purchaser is entitled immediately prior to such reduction with the
result that the Purchaser's overall benefits package is significantly reduced;
(v) the relocation of the Purchaser to a facility or a location more than 50
miles from the Purchaser's then present location, without the Purchaser's
express written consent; (vi) any purported termination of the Purchaser by the
Company which is not effected for death or Disability or for Cause, or any
purported termination for which the grounds relied upon are not valid; or (vii)
the failure of the Company to obtain the assumption of this agreement by any
successors contemplated in Section 4(f) below.

               (f) Successors.

                    (i) Company's Successors. Any successor to the Company
(whether direct or indirect and whether by purchase, merger, consolidation,
liquidation or otherwise) to all or substantially all of the Company's business
and/or assets shall assume the obligations under this Section 4 and agree
expressly to perform the obligations under this Section 4 in the same manner and
to the same extent as the Company would be required to perform such obligations
in the absence of a succession. For all purposes under this Section 4, the term
"COMPANY" shall include any successor to the Company's business and/or assets
which executes and delivers the assumption agreement described in this Section
4(f)(i) or which becomes bound by the terms of this Agreement by operation of
law.

                    (ii) Purchaser's Successors. The terms of this Section 4 and
all rights of the Purchaser hereunder shall inure to the benefit of, and be
enforceable by, the Purchaser's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

        5. Restriction on Transfer.



                                      -3-
<PAGE>   4

               (a) Except for the escrow described below in Section 6, none of
the Shares or any beneficial interest therein shall be transferred, encumbered
or otherwise disposed of in any manner until the release of such Shares from the
Repurchase Option in accordance with the provisions of this Agreement.

               (b) Before any Shares may be sold or transferred (including
transfer by operation of law), such Shares shall first be offered to the Company
(the "RIGHT OF FIRST Refusal").

                    (i) Notice. In the event the Purchaser wishes to sell the
Shares, Purchaser shall deliver a notice ("Notice") to the Company stating (A)
his bona fide intention to sell or transfer such Shares, (B) the number of such
Shares to be sold or transferred, (C) the price for which he proposes to sell or
transfer such Shares, and (D) the name of the proposed purchaser or transferee.

                    (ii) Election to Purchase. Within thirty (30) days after
receipt of the Notice, the Company or its assignee may elect to purchase all or
none of the Shares to which the Notice refers, at the price per share specified
in the Notice. The purchase of the Shares in either such event shall occur at a
closing held at the Company's principal office at a mutually agreed upon time
which in no event shall be more than thirty (30) days following the end of the
time period in which the Company had to elect to purchase such Shares.

                    (iii) Sale of Shares by Purchaser. If all of the Shares to
which the Notice refers are not elected to be purchased, as provided in this
Section 5(b), Purchaser may sell the Shares to any person named in the Notice at
the price specified in the Notice or at a higher price, provided that such sale
or transfer is consummated within sixty (60) days of the date of said Notice to
the Company, and provided, further, that any such sale is in accordance with all
the terms and conditions hereof.

                    (iv) Termination of Restrictions. Notwithstanding the
provisions of Section 5(a) above, the Company's Right of First Refusal shall
terminate immediately as to all Shares upon the occurrence of the first to occur
of the following events:

                         (A) the acquisition of the Company by another entity by
means of the merger or consolidation of the Company with or into another
corporation in which the stock-holders of the Company immediately prior to such
merger or consolidation own less than 50% of the voting securities of the
surviving entity,

                         (B) the sale of all or substantially all of the assets
of the Company, or

                         (C) the date upon which a public market exists for the
Company's capital stock (or any other stock issued to purchasers in exchange for
the Shares purchased under this Agreement). For the purpose of this Agreement, a
"Public Market" shall be deemed to exist if (1) such stock is listed on a
national securities exchange (as that term is used in the Securities Exchange
Act of 1934), or (2) such stock is traded on the over-the-counter market and
prices are published daily on business days in a recognized financial journal.



                                      -4-
<PAGE>   5

                    (v) Assignment. Whenever the Company shall have the right to
purchase Shares under this Section 5, the Company may designate and assign one
or more employees, officers, directors or shareholders of the Company or other
persons or organizations to exercise all of the Company's purchase rights under
this Agreement and purchase all of such Shares; provided that if the fair market
value of the Shares to be purchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the purchase price of the Shares
(determined as described hereinabove) to be purchased, then each such designee
or assignee shall pay the Company cash equal to the difference between the
Repurchase FMV and the purchase price of the Shares which such designee or
assignee shall have the right to purchase.

                    (vi) Exempt Transfers. The provisions of this Section 5
shall not apply to a transfer of any Shares by Purchaser, either during his
lifetime or on death by will or intestacy to his ancestors, descendants or
spouse, or any custodian or trustee for the account of Purchaser or Purchaser's
ancestors, descendants or spouse; provided, in each such case that the
transferee shall receive and hold such Shares subject to all of the provisions
of this Section 5 and there shall be no further transfer of such Shares except
in accordance herewith.

        6. Escrow of Shares. Pursuant to the terms of the Joint Escrow
Instructions attached hereto as EXHIBIT B, the Shares issued under this
Agreement shall be held by the Escrow Agent (as defined in such Joint Escrow
Instructions) along with a stock assignment executed by the Purchaser in blank
in the form attached hereto as EXHIBIT A.

        7. Investment Representations. In connection with the purchase of the
Shares, the Purchaser represents to the Company the following:

               (a) The Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. The
Purchaser is purchasing the Shares for investment for the Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "SECURITIES ACT").

               (b) The Purchaser understands that the Shares have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of the
Purchaser's investment intent as expressed herein. In this connection, the
Purchaser understands that, in the view of the Securities and Exchange
Commission (the "COMMISSION"), the statutory basis for such exemption may not be
present if the Purchaser's representations meant that the Purchaser's present
intention was to hold the Shares for a minimum capital gains period under
applicable tax statutes, for a deferred sale, for a market rise, for a sale if
the market does not rise, or for a year or any other fixed period in the future.

               (c) The Purchaser further acknowledges and understands that the
Shares must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. The
Purchaser further acknowledges and understands that the Company is under no
obligation to register the Shares. The Purchaser understands that the
certificate evidencing the Shares will be imprinted with a legend which
prohibits the transfer of the



                                      -5-
<PAGE>   6

Shares unless they are registered or such registration is not required in the
opinion of counsel satisfactory to the Company.

        8. Stock Certificate Legends. The share certificate evidencing the
Shares issued hereunder shall be endorsed with the following legends:

               (a) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
        FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
        1933. THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
        REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE
        AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
        TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE
        HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION
        AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

               (b) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED
        ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY
        AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF
        THE COMPANY.

               (c) Any legend required by any applicable state securities laws.

        9. Market Stand-Off Agreement. The Purchaser hereby agrees, if so
requested by the managing underwriters or the Company in connection with the
initial public offering of the Company's Common Stock, that, without the prior
written consent of such managing underwriters, the Purchaser will not offer,
sell, contract to sell, grant any option to purchase, make any short sale or
otherwise dispose of, assign any legal or beneficial interest in or make a
distribution of any capital stock of the Company held by or on behalf of the
Purchaser or beneficially owned by the Purchaser in accordance with the rules
and regulations of the Securities and Exchange Commission for a period of up to
180 days after the date of the final prospectus relating to the Company's
initial public offering.

        10. Adjustment for Stock Split. All references to the number of Shares
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, reverse stock split or stock dividend or
other similar change in the Shares which may be made by the Company after the
date of this Agreement.

        11. Tax Consequences. The Purchaser has reviewed with the Purchaser's
own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. The Purchaser understands that the Purchaser
(and not the Company) shall be responsible for the Purchaser's own tax liability
that may arise as a result of this investment or the transactions contemplated
by this Agreement. The Purchaser understands that Section 83 of the Internal
Revenue Code of 1986, as amended (the "CODE"), taxes as ordinary income both (i)
the difference between the fair market value of the Shares



                                      -6-
<PAGE>   7

when the Company granted the Purchaser the right to purchase the Shares and the
fair market value of the Shares on the date of this Agreement, and (ii) the
difference between the amount paid for the Shares and the fair market value of
the Shares as of the date any restrictions on the Shares lapse. In this context,
"restriction" includes the right of the Company to buy back the Shares pursuant
to its repurchase option. In the event the Company has registered under the
Exchange Act, "restriction" with respect to officers, directors and 10%
shareholders also means the period after the purchase of the Shares during which
such officers, directors and 10% shareholders could be subject to suit under
Section 16(b) of the Exchange Act. The Purchaser understands that the Purchaser
may elect to be taxed at the time the Shares are purchased rather than when and
as the Company's repurchase option or 16(b) period expires by filing an election
under Section 83(b) of the Code with the I.R.S. within 30 days from the date of
purchase.

               THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

        12. California Corporate Securities Law. THE SALE OF THE SECURITIES
WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE
COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH
SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR
PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT
FROM THE QUALIFICATION BY SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA
CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY
CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO
EXEMPT.

        13. General Provisions.

               (a) This Agreement shall be governed by the laws of the State of
California. This Agreement represents the entire agreement between the parties
with respect to the purchase of Common Stock by the Purchaser and may only be
modified or amended in writing signed by both parties.

               (b) Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

               (c) The rights and benefits of the Company under this Agreement
shall be transferable to any one or more persons or entities, and all covenants
and agreements hereunder shall inure to the benefit of, and be enforceable by
the Company's successors and assigns. The rights and obligations of the
Purchaser under this Agreement may only be assigned with the prior written
consent of the Company and any purported transfer otherwise shall be null and
void.



                                      -7-
<PAGE>   8

               (d) Either party's failure to enforce any provision or provisions
of this Agreement shall not in any way be construed as a waiver of any such
provision or provisions, nor prevent that party thereafter from enforcing each
and every other provision of this Agreement. The rights granted both parties
herein are cumulative and shall not constitute a waiver of either party's right
to assert all other legal remedies available to it under the circumstances.

               (e) The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

               (f) PURCHASER ACKNOWLEDGES AND AGREES THAT THE LAPSING OF THE
REPURCHASE OPTION PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING
SERVICE AS AN "AT WILL" EMPLOYEE OF THE COMPANY (AND NOT THROUGH THE ACT OF
BEING HIRED OR PURCHASING SHARES HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE
REPURCHASE OPTION SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR
IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS AN EMPLOYEE FOR SUCH PERIOD, FOR ANY
PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH THE COMPANY'S RIGHT TO TERMINATE
PURCHASER'S EMPLOYMENT AT ANY TIME, WITH OR WITHOUT CAUSE.

               (g) Purchaser has reviewed this Agreement in its entirety, has
had an opportunity to obtain the advice of counsel prior to executing this
Agreement and fully understands all provisions of this Agreement.

Palo Alto, California  94304-1050
Attention:  Judith M. O'Brien

Ladies and Gentlemen:

        As escrow agent (the "Escrow Agent") for both Avanex Corporation, a
California corporation (the "Company"), and the undersigned purchaser of stock
of the Company (the "Purchaser"), you are hereby authorized and directed to hold
the documents delivered to you pursuant to the terms of that certain Stock
Purchase Agreement ("Agreement") between the Company and the undersigned (the
"Escrow"), in accordance with the following instructions:

        1. In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the Company's
Repurchase Option (as defined in the Agreement), the Company shall give to
Purchaser and you a written notice specifying the number of shares of stock to
be purchased, the purchase price and the time for a closing hereunder at the
principal office of the Company. Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

        2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, cancellation of indebtedness or some combination thereof) for the
number of shares of stock being purchased pursuant to the exercise of the
Company's repurchase option.

        3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this Escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state


<PAGE>   13

blue sky authority of any required applications for consent to, or notice of
transfer of, the securities. Subject to the provisions of the Agreement and of
this Escrow Agreement, Purchaser shall exercise all rights and privileges of a
shareholder of the Company while the stock is held by you.

        4. Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's repurchase option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many

                                   EXHIBIT D

                               SECURITY AGREEMENT

        This Security Agreement is made as of October 12, 1999 between Avanex

        A. Pledgor has incurred payment obligations (the "Payment Obligations")
to Pledgee set forth in a Promissory Note of even date herewith.

        B. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common Stock of the Pledgee, all options, and similar rights
to acquire such capital stock or interests, and all rights to receive profits or
surplus or other dividends or distributions from the Pledgee to its
shareholders, in each case whether now owned or existing or hereafter acquired
or arising, wherever located, together with all substitutions, replacements,
(the "Shares") to secure performance by Pledgor of the Payment Obligations, all
as more specifically set forth in this Pledge Agreement.

        NOW, THEREFORE, it is agreed as follows:

        (1) Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Stock Purchase Agreement (the

all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number ___, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

        The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Agreement, and
the Pledgeholder shall not encumber or dispose of such Shares except in
accordance with the provisions of this Security Agreement.

        (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

               a. Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

               b. Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.



<PAGE>   19

               c. Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within the meaning of the regulations under Part 207

to cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

        (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

        (4) Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        (5) Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

        (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

               In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

        (7) Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that

<PAGE>   20

principal amount of the Note.

withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

        (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

        (11) Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

        (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein

Non-Transferability of Stock Purchase Right.

     This Stock Purchase Right may not be transferred in any manner otherwise
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Optionee only by Optionee. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

II.  AGREEMENT

     1. Sale of Stock. The Company hereby agrees to sell to the individual named
in the Notice of Grant of Stock Purchase Right (the "Purchaser"), and the
Purchaser hereby agrees to purchase the number of Shares set forth in the Notice
of Grant of Stock Purchase Right, at the

<PAGE>   2

exercise price per share set forth in the Notice of Grant of Stock Purchase
Right (the "Exercise Price"), and subject to the terms and conditions of the
Plan, which is incorporated herein by reference. Subject to 14(c) of the Plan,
in the event of a conflict between the terms and conditions of the Plan and this
Agreement, the terms and conditions of the Plan shall prevail.

     2. Payment of Purchase Price. Purchaser herewith delivers to the Company
the aggregate Exercise Price for the Shares by cash or check or promissory note
in the form of Exhibit C secured by the shares pursuant to a Security Agreement
in the form of Exhibit D.

     3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit B.

     4. Repurchase Option.

          (a) In the event the Purchaser's continuous status as a Service
Provider terminates for any or no reason (including death or Disability), the
Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option for a period
of ninety (90) days from such date to repurchase up to that number of shares
which constitute the Unreleased Shares (as defined in Section 5) at the Exercise
Price per share (the "Repurchase Price") (the "Repurchase Option").

          (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

          (c) Whenever the Company shall have the right to repurchase the
Unreleased Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unreleased Shares. If the Fair Market Value of the
Unreleased Shares to be repurchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of the
Unreleased Shares, then each

                                        2
<PAGE>   3

such designee or assignee shall pay the Company cash equal to the difference
between the Repurchase FMV and the aggregate Repurchase Price of Unreleased
Shares to be purchased.

          (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

     5.   Release of Shares From Repurchase Option.

          (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

               (i) One quarter (1/4) of the Shares shall be released from the
Repurchase Option on November 14, 2000; and

               (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

          (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

          (c) The Shares which have been released from the Repurchase Option
shall be delivered to the Purchaser at the Purchaser's request (see Section 7).

          (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

     For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:

                                       3
<PAGE>   4

               (i) Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities
other than in a private financing transaction approved by the Board of
Directors;

               (ii) the direct or indirect sale or exchange by the shareholders
of the Company of all or substantially all of the stock of the Company;

               (iii) a merger or consolidation in which the Company is a party
and in which the shareholders of the Company before such merger or consolidation
do not retain, directly or indirectly, at a least majority of the beneficial
interest in the voting stock of the Company after such transaction; or

               (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

          (e) Acceleration Upon Termination of Employment. In addition to the
Shares released from the Company's Repurchase Option pursuant to Section 4(d)
above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

               For the purposes of this Section 5(e), the following terms
referred to in this Agreement shall have the following meanings:

               (i) Cause. "Cause" shall mean (i) any act of personal dishonesty
taken by the Purchaser in connection with his responsibilities as an employee
and intended to result in substantial personal enrichment of the Purchaser, (ii)
conviction of a felony that is injurious to the Company, and (iii) a willful act
by the Purchaser which constitutes gross misconduct and which is injurious to
the Company.

               (ii) Disability. "Disability" shall mean that the Purchaser has
been unable to substantially perform his duties as the result of his incapacity
due to physical or mental illness, and such inability, at least 26 weeks after
its commencement, is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the Purchaser or the
Purchaser's legal representative (such agreement as to acceptability not to be
unreasonably withheld).

               (iii) Involuntary Termination. "Involuntary Termination" shall
mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of

                                       4
<PAGE>   5

the Company being acquired and made part of a larger entity (as, for example,
when the Chief Financial Officer of Company remains as such following a Change
of Control and is not made the Chief Financial Officer of the acquiring
corporation) shall not constitute an "Involuntary Termination"; (ii) without the
Purchaser's express written consent, a substantial reduction, without good
business reasons, of the facilities and perquisites (including office space and
location) available to the Purchaser immediately prior to such reduction; (iii)
without the Purchaser's express written consent, a material reduction by the
Company in the base compensation of the Purchaser as in effect immediately prior
to such reduction, or the ineligibility of the Purchaser to continue to
participate in any long-term incentive plan of the Company; (iv) a material
reduction by the Company in the kind or level of employee benefits to which the
Purchaser is entitled immediately prior to such reduction with the result that
the Purchaser's overall benefits package is significantly reduced; (v) the
relocation of the Purchaser to a facility or a location more than 50 miles from
the Purchaser's then present location, without the Purchaser's express written
consent; (vi) any purported termination of the Purchaser by the Company which is
not effected for death or Disability or for Cause, or any purported termination
for which the grounds relied upon are not valid; or (vii) the failure of the
Company to obtain the assumption of this agreement by any successors
contemplated in Section 4(f) below.

               (f) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's
request.

     6.   Restriction on Transfer. Except for the escrow described in Section 7
or transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

     7.   Escrow of Shares.

               (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

               (b) The Escrow Holder shall not be liable for any act it may do
or omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise

                                       5
<PAGE>   6

of its judgment and the Company shall hold Escrow Holder harmless from any and
all such liability, including attorney's fees and other expenses of defending
against the assertion of any such claim.

               (c) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

               (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

               (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Company's Repurchase Option.

     8. Company's Right of First Refusal. Before any Shares held by Purchaser or
any transferee (either being sometimes referred to herein as the "Holder") may
be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

          (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

          (b) Exercise of Right of First Refusal. At any time within thirty (30)
days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

                                       6
<PAGE>   7

          (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.

          (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or (iii) by any combination thereof within thirty (30) days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

          (e) Holder's Right to Transfer. If all of the Shares proposed in the
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section, then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section shall continue to apply to
the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a
new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

          (f) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Purchaser's lifetime or on the Purchaser's death by will or
intestacy to the Purchaser's immediate family or a trust for the benefit of the
Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

          (g) Termination of Right of First Refusal. The Right of First Refusal
shall terminate as to any Shares upon the date of the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
1933 Act.

                                       7
<PAGE>   8

     9.   Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

          (a) Purchaser understands and agrees that the Company shall cause the
legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
          OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
          REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO
          THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE
          OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

          THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A REPURCHASE
          OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE
          RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE ISSUER AND THE
          ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT
          THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT
          OF FIRST REFUSAL AND REPURCHASE OPTION ARE BINDING ON TRANSFEREES OF
          THESE SHARES.

          (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

     10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day

                                       8
<PAGE>   9

period (or such other period as may be requested in writing by the Managing
Underwriter and agreed to in writing by the Company) (the "Market Standoff
Period") following the effective date of a registration statement of the Company
filed under the Securities Act. Such restriction shall apply only to the first
registration statement of the Company to become effective under the Securities
Act that includes securities to be sold on behalf of the Company to the public
in an underwritten public offering under the Securities Act. The Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such Market Standoff Period.

     11.  Tax Consequences. Set forth below is a brief summary as of the date of
grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

          (a) Exercise of Stock Purchase Right. Generally, no income will be
recognized by Purchaser in connection with the exercise of the stock purchaser
right for shares subject to the Repurchase Option, unless an election under
Section 83(b) of the Code is filed with the Internal Revenue Service within 30
days of the date of exercise of the right to purchase stock. The form for making
this election is attached as Exhibit A-4 hereto. Otherwise, as the Company's
repurchase right lapses, Purchaser will recognize compensation income in an
amount equal to the difference between the Fair Market Value of the stock at the
time the Company's repurchase right lapses and the amount paid for the stock, if
any (the "Spread"). If Purchaser is an Employee or former Employee, the Spread
will be subject to tax withholding by the Company, and the Company will be
entitled to a tax deduction in the amount at the time the Purchaser recognizes
ordinary income with respect to a Stock Purchase Right.

          (b) Disposition of Shares. Upon disposition of the Shares, any gain or
loss is treated as capital gain or loss. If the Shares are held for at least one
year, any gain realized on disposition of the shares will be treated as
long-term capital gain for federal income tax purposes. Long-term capital gains
are grouped and netted by holding periods. Net capital gains on assets held for
more than 12 months is capped at 20%. Capital losses are allowed in full against
capital gains, and up to $3,000 against other income.

     THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE RESPONSIBILITY
AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF
THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON
THE PURCHASER'S BEHALF.

     12. No Guarantee of Continued Service. PURCHASER ACKNOWLEDGES AND AGREES
THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO
SECTION 5 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS SERVICE PROVIDER AT THE
WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES
HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE

                                       9
<PAGE>   10

TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
PURCHASER'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.

          13. Notices. Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

     Any notice to the Escrow Holder shall be sent to the Company's address with
a copy to the other party not sending the notice.

     14. No Waiver. Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor prevent that party from thereafter
enforcing each and every other provision of this Agreement. The rights granted
both parties herein are cumulative and shall not constitute a waiver of either
party's right to assert all other legal remedies available to it under the
circumstances.

     15. Successors and Assigns. The Company may assign any of its rights under
this Agreement to single or multiple assignees, and this Agreement shall inure
to the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer herein set forth, this Agreement shall be binding upon
Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     16. Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

     17. Governing Law; Severability. This Agreement is governed by the internal
substantive laws but not the choice of law rules, of California.

     18. Entire Agreement. The Plan is incorporated herein by reference. This
Agreement (including the exhibits referenced herein), the Plan, and the
Investment Representation Statement constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Purchaser with
respect to the subject matter hereof, and may not be modified adversely to the
Purchaser's interest except by means of a writing signed by the Company and
Purchaser.

Corporate Secretary
Avanex Corporation
40919 Encyclopedia Circle
Fremont, CA 94538-2436

Dear Sirs:

     As Escrow Agent for both Avanex Corporation, a California corporation (the
"Company"), and the undersigned purchaser of stock of the Company (the
"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

     1. In the event the Company and/or any assignee of the Company (referred to
collectively for convenience herein as the "Company") exercises the Company's
repurchase option set forth in the Agreement (the "Repurchase Option"), the
Company shall give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Company. Purchaser and the
Company hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

     2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, or some combination thereof) for the number of shares of stock
being purchased pursuant to the exercise of the Company's Repurchase Option.

     3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky

the securities. Subject to the provisions of this paragraph 3, Purchaser shall
exercise all rights and privileges of a shareholder of the Company while the
stock is held by you.

<PAGE>   14

     4. Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's Repurchase Option has been exercised, you
will deliver to Purchaser a certificate or certificates representing so many
shares of stock as are not then subject to the Company's Repurchase Option.
Within ninety (90) days after cessation of Purchaser's continuous employment by
or services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's Repurchase

                       INVESTMENT REPRESENTATION STATEMENT


     PURCHASER: ANTHONY FLORENCE

     COMPANY:   AVANEX CORPORATION

     SECURITY:  COMMON STOCK

     AMOUNT:    130,000 SHARES

     DATE:      NOVEMBER 19, 1999


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

     (b) reach an informed and knowledgeable decision to acquire the Securities.
Purchaser is acquiring these Securities for investment for Purchaser's own
account only and not with a view to, or for resale in connection with, any
"distribution" thereof within the meaning of the Securities Act of 1933, as
amended (the "Securities Act").

     (c) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein. In this connection, Purchaser understands
that, in the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Purchaser's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one (1) year or any other fixed period in the future. Purchaser
further understands that the Securities must be held indefinitely unless they
are subsequently registered under the Securities Act or an exemption from such
registration is available. Purchaser further acknowledges and understands that
the Company is under no obligation to register the Securities.

     (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Stock Purchase Right to the Purchaser, the
exercise will be exempt from registration under the Securities Act. In the event
the Company becomes subject to the reporting

<PAGE>   20

requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
ninety (90) days thereafter (or such longer period as any market stand-off
agreement may require) the Securities exempt under Rule 701 may be resold,
subject to the satisfaction of certain of the conditions specified by Rule 144,
including: (1) the resale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934); and, in the case of
an affiliate, (2) the availability of certain public information about the
Company, (3) the amount of Securities being sold during any three (3) month
period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                        Signature of Purchaser:


                                        /s/ ANTHONY FLORENCE

                               SECURITY AGREEMENT

          This Security Agreement is made as of November 19, 1999 between Avanex
Corporation ("Pledgee"), Anthony Florence ("Pledgor") and the Secretary of
Pledgee as "Pledgeholder."

                                    Recitals

          A. Pledgor has incurred payment obligations (the "Payment
Obligations") to Pledgee set forth in a Promissory Note of even date herewith.

          B. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common

     Stock of the Pledgee, all options, and similar rights to acquire such
capital stock or interests, and all rights to receive profits or surplus or
other dividends or distributions from the Pledgee to its shareholders, in each
case whether now owned or existing or hereafter acquired or arising, wherever
located, together with all substitutions, replacements, (the "Shares") to secure
performance by Pledgor of the Payment Obligations, all as more specifically set
forth in this Pledge Agreement.

          NOW, THEREFORE, it is agreed as follows:

     (1) Creation and Description of Security Interest. In consideration of the
transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement"), Pledgor, pursuant to the California Commercial Code, hereby
pledges all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number __, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

          The pledged stock (together with an executed blank stock assignment
for use in transferring all or a portion of the Shares to Pledgee if, as and
when required pursuant to this Security Agreement) shall be held by the
Pledgeholder as security for the repayment of the Note, and any extensions or
renewals thereof, to be executed by Pledgor pursuant to the terms of the
Agreement, and the Pledgeholder shall not encumber or dispose of such Shares
except in accordance with the provisions of this Security Agreement.

<PAGE>   22

     (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

          (a) Payment of Indebtedness. Pledgor will pay the principal sum of the
          Note secured hereby, together with interest thereon, at the time and
          in the manner provided in the Note.

          (b) Encumbrances. The Shares are free of all other encumbrances,
          defenses and liens, and Pledgor will not further encumber the Shares
          without the prior written consent of Pledgee.

          (c) Margin Regulations. In the event that Pledgee's Common Stock is
          now or later becomes margin-listed by the Federal Reserve Board and
          Pledgee is classified as a "lender" within the meaning of the
          regulations under Part 207 of Title 12 of the Code of Federal
          Regulations ("Regulation G"), Pledgor agrees to cooperate with Pledgee
          in making any amendments to the Note or providing any additional
          collateral as may be necessary to comply with such regulations.

     (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

     (4) Stock Adjustments. In the event that during the term of the pledge any
stock dividend, reclassification, readjustment or other changes are declared or
made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

     (5) Options and Rights. In the event that, during the term of this pledge,
subscription Options or other rights or options shall be issued in connection
with the pledged Shares, such rights, Options and options shall be the property
of Pledgor and, if exercised by Pledgor, all new stock or other securities so
acquired by Pledgor as it relates to the pledged Shares then held by
Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

                                      -2-
<PAGE>   23

     (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

          a. Payment of principal or interest on the Note shall be delinquent
for a period of 10 days or more; or

          b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

          In the case of an event of Default, as set forth above, Pledgee shall
have the right to accelerate payment of the Note upon notice to Pledgor, and
Pledgee shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

     (7) Release of Collateral. Subject to any applicable contrary rules under
Regulation G, there shall be released from this pledge a portion of the pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

     (8) Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

     (9) Term. The within pledge of Shares shall continue until the payment of
all indebtedness secured hereby, at which time the remaining pledged stock shall
be promptly delivered to Pledgor, subject to the provisions for prior release of
a portion of the Collateral as provided in paragraph 7 above.

     (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

     (11) Pledgeholder Liability. In the absence of willful or gross negligence,
Pledgeholder shall not be liable to any party for any of his acts, or omissions
to act, as Pledgeholder.

     (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

     (13) Successors or Assigns. Pledgor and Pledgee agree that all of the terms
of this Security Agreement shall be binding on their respective successors and
assigns, and that the term

                                      -3-

governed under the laws of the State of California.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

        Unless otherwise defined herein, the terms defined in the 1998 Stock

Agreement (the "Agreement").

I.      NOTICE OF GRANT OF STOCK PURCHASE RIGHT

        JESSY CHAO

        You have been granted the right to purchase Common Stock of the Company,
subject to the terms and conditions of the Plan and this Agreement, as follows:

        Expiration Date                            February 25, 2000

        YOU MUST EXERCISE THIS STOCK PURCHASE RIGHT BEFORE THE EXPIRATION DATE
OR IT WILL TERMINATE AND YOU WILL HAVE NO FURTHER RIGHT TO PURCHASE THE SHARES.

Non-Transferability of Stock Purchase Right.

        This Stock Purchase Right may not be transferred in any manner otherwise
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Optionee only by Optionee. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

II.     AGREEMENT

        1. Sale of Stock. The Company hereby agrees to sell to the individual
named in the Notice of Grant of Stock Purchase Right (the "Purchaser"), and the
Purchaser hereby agrees to purchase the number of Shares set forth in the Notice
of Grant of Stock Purchase Right, at the


<PAGE>   2

exercise price per share set forth in the Notice of Grant of Stock Purchase
Right (the "Exercise Price"), and subject to the terms and conditions of the
Plan, which is incorporated herein by reference. Subject to 14(c) of the Plan,
in the event of a conflict between the terms and conditions of the Plan and this
Agreement, the terms and conditions of the Plan shall prevail.

        2. Payment of Purchase Price. Purchaser herewith delivers to the Company
the aggregate Exercise Price for the Shares by cash or check or promissory note
in the form of Exhibit C secured by the shares pursuant to a Security Agreement
in the form of Exhibit D.

        3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit B.

        4. Repurchase Option.

               (a) In the event the Purchaser's continuous status as a Service
Provider terminates for any or no reason (including death or Disability), the
Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option for a period
of ninety (90) days from such date to repurchase up to that number of shares
which constitute the Unreleased Shares (as defined in Section 5) at the Exercise
Price per share (the "Repurchase Price") (the "Repurchase Option").

               (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

               (c) Whenever the Company shall have the right to repurchase the
Unreleased Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unreleased Shares. If the Fair Market Value of the
Unreleased Shares to be repurchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of the
Unreleased Shares, then each



                                       2
<PAGE>   3

such designee or assignee shall pay the Company cash equal to the difference
between the Repurchase FMV and the aggregate Repurchase Price of Unreleased
Shares to be purchased.

               (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

        5. Release of Shares From Repurchase Option.

               (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

                    (i)One quarter (1/4) of the Shares shall be released from
the Repurchase Option on November 22, 2000; and

                    (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

               (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

               (c) The Shares which have been released from the Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request (see
Section 7).

               (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

        For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:



                                       3
<PAGE>   4

                    (i) Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities
other than in a private financing transaction approved by the Board of
Directors;

                    (ii) the direct or indirect sale or exchange by the
shareholders of the Company of all or substantially all of the stock of the
Company;

                    (iii) a merger or consolidation in which the Company is a
party and in which the shareholders of the Company before such merger or
consolidation do not retain, directly or indirectly, at a least majority of the
beneficial interest in the voting stock of the Company after such transaction;
or

                    (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

        For the purposes of this Section 5(e), the following terms referred to
in this Agreement shall have the following meanings:

                    (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

                    (ii) Disability. "Disability" shall mean that the Purchaser
has been unable to substantially perform his duties as the result of his
incapacity due to physical or mental illness, and such inability, at least 26
weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the
Purchaser or the Purchaser's legal representative (such agreement as to
acceptability not to be unreasonably withheld).

                    (iii) Involuntary Termination. "Involuntary Termination"
shall mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of



                                       4
<PAGE>   5

the Company being acquired and made part of a larger entity (as, for example,
when the Chief Financial Officer of Company remains as such following a Change
of Control and is not made the Chief Financial Officer of the acquiring
corporation) shall not constitute an "Involuntary Termination"; (ii) without the
Purchaser's express written consent, a substantial reduction, without good
business reasons, of the facilities and perquisites (including office space and
location) available to the Purchaser immediately prior to such reduction; (iii)
without the Purchaser's express written consent, a material reduction by the
Company in the base compensation of the Purchaser as in effect immediately prior
to such reduction, or the ineligibility of the Purchaser to continue to
participate in any long-term incentive plan of the Company; (iv) a material
reduction by the Company in the kind or level of employee benefits to which the
Purchaser is entitled immediately prior to such reduction with the result that
the Purchaser's overall benefits package is significantly reduced; (v) the
relocation of the Purchaser to a facility or a location more than 50 miles from
the Purchaser's then present location, without the Purchaser's express written
consent; (vi) any purported termination of the Purchaser by the Company which is
not effected for death or Disability or for Cause, or any purported termination
for which the grounds relied upon are not valid; or (vii) the failure of the
Company to obtain the assumption of this agreement by any successors
contemplated in Section 4(f) below.

               (f) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's
request.

        6. Restriction on Transfer. Except for the escrow described in Section 7
or transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

        7. Escrow of Shares.

               (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

               (b) The Escrow Holder shall not be liable for any act it may do
or omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise



                                       5
<PAGE>   6

of its judgment and the Company shall hold Escrow Holder harmless from any and
all such liability, including attorney's fees and other expenses of defending
against the assertion of any such claim.

               (c) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

               (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

               (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Company's Repurchase Option.

        8. Company's Right of First Refusal. Before any Shares held by Purchaser
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

               (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

               (b) Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.



                                       6
<PAGE>   7

               (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.

               (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or (iii) by any combination thereof within thirty (30) days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

               (e) Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section shall continue to apply to
the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a
new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

               (f) Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

               (g) Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the date of the first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the 1933 Act.



                                       7

        9. Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

               (a) Purchaser understands and agrees that the Company shall cause
the legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
               SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
               UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL
               SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE
               OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
               RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A
               REPURCHASE OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET
               FORTH IN THE RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE
               ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH
               MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH
               TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND REPURCHASE
               OPTION ARE BINDING ON TRANSFEREES OF THESE SHARES.

               (b) Stop-Transfer Notices. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

        10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day



                                       8
<PAGE>   9

period (or such other period as may be requested in writing by the Managing
Underwriter and agreed to in writing by the Company) (the "Market Standoff
Period") following the effective date of a registration statement of the Company
filed under the Securities Act. Such restriction shall apply only to the first
registration statement of the Company to become effective under the Securities
Act that includes securities to be sold on behalf of the Company to the public
in an underwritten public offering under the Securities Act. The Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such Market Standoff Period.

        11. Tax Consequences. Set forth below is a brief summary as of the date
of grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

               (a) Exercise of Stock Purchase Right. Generally, no income will
be recognized by Purchaser in connection with the exercise of the stock
purchaser right for shares subject to the Repurchase Option, unless an election
under Section 83(b) of the Code is filed with the Internal Revenue Service
within 30 days of the date of exercise of the right to purchase stock. The form
for making this election is attached as Exhibit A-4 hereto. Otherwise, as the
Company's repurchase right lapses, Purchaser will recognize compensation income
in an amount equal to the difference between the Fair Market Value of the stock
at the time the Company's repurchase right lapses and the amount paid for the
stock, if any (the "Spread"). If Purchaser is an Employee or former Employee,
the Spread will be subject to tax withholding by the Company, and the Company
will be entitled to a tax deduction in the amount at the time the Purchaser
recognizes ordinary income with respect to a Stock Purchase Right.

               (b) Disposition of Shares. Upon disposition of the Shares, any
gain or loss is treated as capital gain or loss. If the Shares are held for at
least one year, any gain realized on disposition of the shares will be treated
as long-term capital gain for federal income tax purposes. Long-term capital
gains are grouped and netted by holding periods. Net capital gains on assets
held for more than 12 months is capped at 20%. Capital losses are allowed in
full against capital gains, and up to $3,000 against other income.

        THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

Dear Sirs:

        As Escrow Agent for both Avanex Corporation, a California corporation

"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

        1. In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the Company's
repurchase option set forth in the Agreement (the "Repurchase Option"), the
Company shall give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Company. Purchaser and the
Company hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

        2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, or some combination thereof) for the number of shares of stock
being purchased pursuant to the exercise of the Company's Repurchase Option.

        3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky

the securities. Subject to the provisions of this paragraph 3, Purchaser shall
exercise all rights and privileges of a shareholder of the Company while the
stock is held by you.

        4. Upon written request of the Purchaser, but no more than once per
calendar year, unless the Company's Repurchase Option has been exercised, you

shares of stock as are not then subject to the Company's Repurchase Option.
Within ninety (90) days after cessation of Purchaser's continuous employment by
or services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's Repurchase
Option.

        5. If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you shall deliver all of the same to Purchaser and shall be discharged of all
further obligations hereunder.

        6. Your duties hereunder may be altered, amended, modified or revoked

vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

any such proceedings.

                       INVESTMENT REPRESENTATION STATEMENT

        PURCHASER:           JESSY CHAO

        COMPANY:             AVANEX CORPORATION

        SECURITY:            COMMON STOCK

        AMOUNT:              100,000 SHARES

        DATE:                NOVEMBER 26, 1999

        In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

        (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

        (b) reach an informed and knowledgeable decision to acquire the
Securities. Purchaser is acquiring these Securities for investment for
Purchaser's own account only and not with a view to, or for resale in connection
with, any "distribution" thereof within the meaning of the Securities Act of
1933, as amended (the "Securities Act").

        (c) Purchaser acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Purchaser's investment intent as expressed herein. In this connection,
Purchaser understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Purchaser's representation was predicated solely upon a present intention to
hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one (1) year or any other
fixed period in the future. Purchaser further understands that the Securities
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
further acknowledges and understands that the Company is under no obligation to
register the Securities.

        (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Stock Purchase Right to the Purchaser, the
exercise will be exempt from registration under the Securities Act. In the event
the Company becomes subject to the reporting


<PAGE>   20

requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
ninety (90) days thereafter (or such longer period as any market stand-off
agreement may require) the Securities exempt under Rule 701 may be resold,
subject to the satisfaction of certain of the conditions specified by Rule 144,
including: (1) the resale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934); and, in the case of
an affiliate, (2) the availability of certain public information about the
Company, (3) the amount of Securities being sold during any three (3) month
period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (e) Purchaser further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that

                               SECURITY AGREEMENT

               This Security Agreement is made as of November 26, 1999 between
Avanex Corporation ("Pledgee"), Jessy Chao ("Pledgor") and the Secretary of
Pledgee as "Pledgeholder."

                                    Recitals

               A. Pledgor has incurred payment obligations (the "Payment
Obligations") to Pledgee set forth in a Promissory Note of even date herewith.

               B. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common

        Stock of the Pledgee, all options, and similar rights to acquire such
capital stock or interests, and all rights to receive profits or surplus or
other dividends or distributions from the Pledgee to its shareholders, in each
case whether now owned or existing or hereafter acquired or arising, wherever
located, together with all substitutions, replacements, (the "Shares") to secure
performance by Pledgor of the Payment Obligations, all as more specifically set
forth in this Pledge Agreement.

               NOW, THEREFORE, it is agreed as follows:

        (1) Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement"), Pledgor, pursuant to the California Commercial Code, hereby
pledges all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number __, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

               The pledged stock (together with an executed blank stock
assignment for use in transferring all or a portion of the Shares to Pledgee if,
as and when required pursuant to this Security Agreement) shall be held by the
Pledgeholder as security for the repayment of the Note, and any extensions or
renewals thereof, to be executed by Pledgor pursuant to the terms of the
Agreement, and the Pledgeholder shall not encumber or dispose of such Shares
except in accordance with the provisions of this Security Agreement.



<PAGE>   22






        (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

               (a) Payment of Indebtedness. Pledgor will pay the principal sum
               of the Note secured hereby, together with interest thereon, at
               the time and in the manner provided in the Note.

               (b) Encumbrances. The Shares are free of all other encumbrances,
               defenses and liens, and Pledgor will not further encumber the
               Shares without the prior written consent of Pledgee.

               (c) Margin Regulations. In the event that Pledgee's Common Stock
               is now or later becomes margin-listed by the Federal Reserve
               Board and Pledgee is classified as a "lender" within the meaning
               of the regulations under Part 207 of Title 12 of the Code of
               Federal Regulations ("Regulation G"), Pledgor agrees to cooperate
               with Pledgee in making any amendments to the Note or providing
               any additional collateral as may be necessary to comply with such
               regulations.

        (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

        (4) Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        (5) Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.



<PAGE>   23






        (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

               In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

        (7) Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

        (8) Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

        (9) Term. The within pledge of Shares shall continue until the payment
of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

        (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

        (11) Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

        (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

        (13) Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term



                                      -3-
<PAGE>   24

"Pledgor" and the term "Pledgee" as used herein shall be deemed to include, for
all purposes, the respective designees, successors, assigns, heirs, executors
and administrators.

        (14) Governing Law. This Security Agreement shall be interpreted and
governed under the laws of the State of California.

               IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first above written.

        Expiration Date                            February 25, 2000

        YOU MUST EXERCISE THIS STOCK PURCHASE RIGHT BEFORE THE EXPIRATION DATE
OR IT WILL TERMINATE AND YOU WILL HAVE NO FURTHER RIGHT TO PURCHASE THE SHARES.

Non-Transferability of Stock Purchase Right.

        This Stock Purchase Right may not be transferred in any manner otherwise
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Optionee only by Optionee. The terms of the Plan and this
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

II.     AGREEMENT

        1. Sale of Stock. The Company hereby agrees to sell to the individual
named in the Notice of Grant of Stock Purchase Right (the "Purchaser"), and the
Purchaser hereby agrees to purchase the number of Shares set forth in the Notice
of Grant of Stock Purchase Right, at the


<PAGE>   2

exercise price per share set forth in the Notice of Grant of Stock Purchase
Right (the "Exercise Price"), and subject to the terms and conditions of the
Plan, which is incorporated herein by reference. Subject to 14(c) of the Plan,
in the event of a conflict between the terms and conditions of the Plan and this
Agreement, the terms and conditions of the Plan shall prevail.

        2. Payment of Purchase Price. Purchaser herewith delivers to the Company
the aggregate Exercise Price for the Shares by cash or check or promissory note
in the form of Exhibit C secured by the shares pursuant to a Security Agreement
in the form of Exhibit D.

        3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit B.

        4. Repurchase Option.

               (a) In the event the Purchaser's continuous status as a Service
Provider terminates for any or no reason (including death or Disability), the
Company shall, upon the date of such termination (as reasonably fixed and
determined by the Company), have an irrevocable, exclusive option for a period
of ninety (90) days from such date to repurchase up to that number of shares
which constitute the Unreleased Shares (as defined in Section 5) at the Exercise
Price per share (the "Repurchase Price") (the "Repurchase Option").

               (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) AND, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unreleased Shares being repurchased and
all rights and interests therein or relating thereto, and the Company shall have
the right to retain and transfer to its own name the number of Unreleased Shares
being repurchased by the Company.

               (c) Whenever the Company shall have the right to repurchase the
Unreleased Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unreleased Shares. If the Fair Market Value of the
Unreleased Shares to be repurchased on the date of such designation or
assignment (the "Repurchase FMV") exceeds the aggregate Repurchase Price of the
Unreleased Shares, then each



                                       2
<PAGE>   3

such designee or assignee shall pay the Company cash equal to the difference
between the Repurchase FMV and the aggregate Repurchase Price of Unreleased
Shares to be purchased.

               (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

        5. Release of Shares From Repurchase Option.

               (a) As of the date of this Agreement, all of the Shares shall be
subject to the Company's Repurchase Option. The Shares shall be released from
the Repurchase Option as follows:

                    (i) One quarter (1/4) of the Shares shall be released from
the Repurchase Option on November 22, 2000; and

                    (ii) One forty-eighth (1/48) shall be released from the
Repurchase Option each full calendar month elapsing thereafter during all of
which Purchaser was a full time employee of the Company.

               (b) Any of the Shares which, from time to time, have not yet been
released from the Repurchase Option are referred to herein as "Unreleased
Shares."

               (c) The Shares which have been released from the Repurchase
Option shall be delivered to the Purchaser at the Purchaser's request (see
Section 7).

               (d) Notwithstanding the foregoing, upon a Change of Control, as
defined below, for any reason that occurs while Purchaser is an employee of the
Company, that number of Unreleased Shares, if any, which, when aggregated with
any Shares previously released from the Repurchase Option, are required to equal
fifty percent (50%) of the Shares shall be released from the Repurchase Option
on the date the event constituting a Change of Control is consummated. The
balance of the Shares subject to the Repurchase Option shall continue to be
released from the Repurchase Option on the same schedule (i.e., the same number
of shares shall vest each month) as existed prior to the Change of Control. For
example, if a Change of Control occurs on a date where 25% of Purchaser's Shares
have been released from the Company's Purchase Option, then an additional 25% of
the Shares shall be released from the Purchase Option pursuant hereto. The
remaining 50% of the Shares shall vest at the rate of 1/48th of the Shares per
month thereafter, such that all Shares are fully vested after an additional
24-month period. If a Change of Control occurs on a date where more than 50% of
Purchaser's Shares have already been released from the Company's Purchase
Option, then no additional Shares shall be released from the Purchase Option.

        For the purposes of the foregoing, a Change of Control shall mean the
occurrence of any of the following events:



                                       3
<PAGE>   4

                    (i) Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities
other than in a private financing transaction approved by the Board of
Directors;

                    (ii) the direct or indirect sale or exchange by the
shareholders of the Company of all or substantially all of the stock of the
Company;

                    (iii) a merger or consolidation in which the Company is a
party and in which the shareholders of the Company before such merger or
consolidation do not retain, directly or indirectly, at a least majority of the
beneficial interest in the voting stock of the Company after such transaction;
or

                    (iv) the sale or disposition by the Company of all or
substantially all the Company's assets.

               (e) Acceleration Upon Termination of Employment. In addition to
the Shares released from the Company's Repurchase Option pursuant to Section
4(d) above, in the event the Purchaser's employment terminates as a result of an
Involuntary Termination other than for Cause upon or within 12 months after a
Change of Control, all Unreleased Shares shall be released from the Company's
Purchase Option upon the date of such termination.

        For the purposes of this Section 5(e), the following terms referred to
in this Agreement shall have the following meanings:

                    (i) Cause. "Cause" shall mean (i) any act of personal
dishonesty taken by the Purchaser in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of the
Purchaser, (ii) conviction of a felony that is injurious to the Company, and
(iii) a willful act by the Purchaser which constitutes gross misconduct and
which is injurious to the Company.

                    (ii) Disability. "Disability" shall mean that the Purchaser
has been unable to substantially perform his duties as the result of his
incapacity due to physical or mental illness, and such inability, at least 26
weeks after its commencement, is determined to be total and permanent by a
physician selected by the Company or its insurers and acceptable to the
Purchaser or the Purchaser's legal representative (such agreement as to
acceptability not to be unreasonably withheld).

                    (iii) Involuntary Termination. "Involuntary Termination"
shall mean (i) without the Purchaser's express written consent, the significant
reduction of the Purchaser's duties or responsibilities relative to the
Purchaser's duties or responsibilities in effect immediately prior to such
reduction; provided, however, that a reduction in duties or responsibilities
solely by virtue of



                                       4
<PAGE>   5

the Company being acquired and made part of a larger entity (as, for example,
when the Chief Financial Officer of Company remains as such following a Change
of Control and is not made the Chief Financial Officer of the acquiring
corporation) shall not constitute an "Involuntary Termination"; (ii) without the
Purchaser's express written consent, a substantial reduction, without good
business reasons, of the facilities and perquisites (including office space and
location) available to the Purchaser immediately prior to such reduction; (iii)
without the Purchaser's express written consent, a material reduction by the
Company in the base compensation of the Purchaser as in effect immediately prior
to such reduction, or the ineligibility of the Purchaser to continue to
participate in any long-term incentive plan of the Company; (iv) a material
reduction by the Company in the kind or level of employee benefits to which the
Purchaser is entitled immediately prior to such reduction with the result that
the Purchaser's overall benefits package is significantly reduced; (v) the
relocation of the Purchaser to a facility or a location more than 50 miles from
the Purchaser's then present location, without the Purchaser's express written
consent; (vi) any purported termination of the Purchaser by the Company which is
not effected for death or Disability or for Cause, or any purported termination
for which the grounds relied upon are not valid; or (vii) the failure of the
Company to obtain the assumption of this agreement by any successors
contemplated in Section 4(f) below.

               (f) The Shares which have been released from the Company's
Repurchase Option shall be delivered to the Purchaser at the Purchaser's
request.

        6. Restriction on Transfer. Except for the escrow described in Section 7
or transfer of the Shares to the Company or its assignees contemplated by this
Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until the release of
such Shares from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

        7. Escrow of Shares.

               (a) To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon exercise of the Repurchase Option by the Company, the
Purchaser shall, upon execution of this Agreement, deliver and deposit with an
escrow holder designated by the Company (the "Escrow Holder") the share
certificates representing the Unreleased Shares, together with the Assignment
Separate from Certificate (the "Stock Assignment") duly endorsed in blank,
attached hereto as Exhibit A-1. The Unreleased Shares and Stock Assignment shall
be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the
Company and Purchaser attached as Exhibit A-2 hereto, until such time as the
Company's Repurchase Option expires. As a further condition to the Company's
obligations under this Agreement, the spouse of Purchaser, if any, shall execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

               (b) The Escrow Holder shall not be liable for any act it may do
or omit to do with respect to holding the Unreleased Shares in escrow and while
acting in good faith and in the exercise



                                       5
<PAGE>   6

of its judgment and the Company shall hold Escrow Holder harmless from any and
all such liability, including attorney's fees and other expenses of defending
against the assertion of any such claim.

               (c) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

               (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from such Repurchase
Option, upon Purchaser's request the Escrow Holder shall promptly cause a new
certificate to be issued for such released Shares and shall deliver such
certificate to the Company or the Purchaser, as the case may be.

               (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Company's Repurchase Option.

        8. Company's Right of First Refusal. Before any Shares held by Purchaser
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this (the "Right of
First Refusal").

               (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).

               (b) Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.



                                       6
<PAGE>   7

               (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are not Unreleased Shares, or
(ii) in the case of Shares that are Unreleased Shares, the lower of the Offered
Price or the Repurchase Price as defined in Section 4(a) hereof. If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the
Company in good faith.

               (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), (i) by cash or check, (ii) by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or (iii) by any combination thereof within thirty (30) days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

               (e) Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section shall continue to apply to
the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a
new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

               (f) Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section, provided that the Purchaser notifies the Company in writing within
thirty (30) days of said transfer. "Immediate Family" as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In
such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not
limited to this Section and Section 4, and there shall be no further transfer of
such Shares except in accordance with the terms of this Section.

               (g) Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the date of the first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the 1933 Act.

        9. Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

               (a) Purchaser understands and agrees that the Company shall cause
the legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
               SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
               UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL
               SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE
               OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
               RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL, AND A
               REPURCHASE OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET
               FORTH IN THE RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE
               ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH
               MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH
               TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND REPURCHASE
               OPTION ARE BINDING ON TRANSFEREES OF THESE SHARES.

               (b) Stop-Transfer Notices. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

        10. Lock-Up Period. Purchaser hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Purchaser shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day



                                       8
<PAGE>   9

period (or such other period as may be requested in writing by the Managing
Underwriter and agreed to in writing by the Company) (the "Market Standoff
Period") following the effective date of a registration statement of the Company
filed under the Securities Act. Such restriction shall apply only to the first
registration statement of the Company to become effective under the Securities
Act that includes securities to be sold on behalf of the Company to the public
in an underwritten public offering under the Securities Act. The Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such Market Standoff Period.

        11. Tax Consequences. Set forth below is a brief summary as of the date
of grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

               (a) Exercise of Stock Purchase Right. Generally, no income will
be recognized by Purchaser in connection with the exercise of the stock
purchaser right for shares subject to the Repurchase Option, unless an election
under Section 83(b) of the Code is filed with the Internal Revenue Service
within 30 days of the date of exercise of the right to purchase stock. The form
for making this election is attached as Exhibit A-4 hereto. Otherwise, as the
Company's repurchase right lapses, Purchaser will recognize compensation income
in an amount equal to the difference between the Fair Market Value of the stock
at the time the Company's repurchase right lapses and the amount paid for the
stock, if any (the "Spread"). If Purchaser is an Employee or former Employee,
the Spread will be subject to tax withholding by the Company, and the Company
will be entitled to a tax deduction in the amount at the time the Purchaser
recognizes ordinary income with respect to a Stock Purchase Right.

               (b) Disposition of Shares. Upon disposition of the Shares, any
gain or loss is treated as capital gain or loss. If the Shares are held for at
least one year, any gain realized on disposition of the shares will be treated
as long-term capital gain for federal income tax purposes. Long-term capital
gains are grouped and netted by holding periods. Net capital gains on assets
held for more than 12 months is capped at 20%. Capital losses are allowed in
full against capital gains, and up to $3,000 against other income.

        THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

        12. No Guarantee of Continued Service. PURCHASER ACKNOWLEDGES AND AGREES
THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO
SECTION 5 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS SERVICE PROVIDER AT THE
WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES
HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE



                                       9
<PAGE>   10

TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE
PURCHASER'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE.

        13. Notices. Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

        Any notice to the Escrow Holder shall be sent to the Company's address
with a copy to the other party not sending the notice.

        14. No Waiver. Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor prevent that party from thereafter
enforcing each and every other provision of this Agreement. The rights granted
both parties herein are cumulative and shall not constitute a waiver of either
party's right to assert all other legal remedies available to it under the
circumstances.

        15. Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

        16. Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

        17. Governing Law; Severability. This Agreement is governed by the
internal substantive laws but not the choice of law rules, of California.

        18. Entire Agreement. The Plan is incorporated herein by reference. This
Agreement (including the exhibits referenced herein), the Plan, and the
Investment Representation Statement constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Purchaser with
respect to the subject matter hereof, and may not be modified adversely to the
Purchaser's interest except by means of a writing signed by the Company and
Purchaser.

Dear Sirs:

        As Escrow Agent for both Avanex Corporation, a California corporation

"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

        1. In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the Company's
repurchase option set forth in the Agreement (the "Repurchase Option"), the
Company shall give to Purchaser and you a written notice specifying the number
of shares of stock to be purchased, the purchase price, and the time for a
closing hereunder at the principal office of the Company. Purchaser and the
Company hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

        2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, or some combination thereof) for the number of shares of stock
being purchased pursuant to the exercise of the Company's Repurchase Option.

        3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any

including but not limited to the filing with any applicable state blue sky
authority of any required applications for consent to, or notice of transfer of,
the securities. Subject to the provisions of this paragraph 3, Purchaser shall
exercise all rights and privileges of a shareholder of the Company while the
stock is held by you.

number of shares held or issued pursuant to the Agreement and not purchased by
the Company or its assignees pursuant to exercise of the Company's Repurchase
Option.

authorities or rights of the parties executing or delivering or purporting to

securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

                       INVESTMENT REPRESENTATION STATEMENT

        PURCHASER:           PAUL SHI-QI JIANG

        COMPANY:             AVANEX CORPORATION

        SECURITY:            COMMON STOCK

        AMOUNT:              100,000 SHARES

        DATE:                NOVEMBER 26, 1999

        In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

        (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to

        (b) reach an informed and knowledgeable decision to acquire the
Securities. Purchaser is acquiring these Securities for investment for
Purchaser's own account only and not with a view to, or for resale in connection
with, any "distribution" thereof within the meaning of the Securities Act of
1933, as amended (the "Securities Act").

        (c) Purchaser acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Purchaser's investment intent as expressed herein. In this connection,
Purchaser understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Purchaser's representation was predicated solely upon a present intention to
hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one (1) year or any other
fixed period in the future. Purchaser further understands that the Securities
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
further acknowledges and understands that the Company is under no obligation to
register the Securities.

        (d) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Stock Purchase Right to the Purchaser, the
exercise will be exempt from registration under the Securities Act. In the event
the Company becomes subject to the reporting


<PAGE>   20

requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
ninety (90) days thereafter (or such longer period as any market stand-off
agreement may require) the Securities exempt under Rule 701 may be resold,
subject to the satisfaction of certain of the conditions specified by Rule 144,
including: (1) the resale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934); and, in the case of
an affiliate, (2) the availability of certain public information about the
Company, (3) the amount of Securities being sold during any three (3) month
period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (e) Purchaser further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                       Signature of Purchaser: /s/ PAUL SHI-QI JIANG

                               SECURITY AGREEMENT

               This Security Agreement is made as of November 26, 1999 between
Avanex Corporation ("Pledgee"), Paul Shi-Qi Jiang ("Pledgor") and the Secretary
of Pledgee as "Pledgeholder."

                                    Recitals

               A. Pledgor has incurred payment obligations (the "Payment
Obligations") to Pledgee set forth in a Promissory Note of even date herewith.

               B. Pledgor desires to provide a security interest in all of the
Pledgor's shares of Common

        Stock of the Pledgee, all options, and similar rights to acquire such
capital stock or interests, and all rights to receive profits or surplus or
other dividends or distributions from the Pledgee to its shareholders, in each
case whether now owned or existing or hereafter acquired or arising, wherever
located, together with all substitutions, replacements, (the "Shares") to secure
performance by Pledgor of the Payment Obligations, all as more specifically set
forth in this Pledge Agreement.

               NOW, THEREFORE, it is agreed as follows:

        (1) Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Stock Purchase Agreement (the
"Agreement"), Pledgor, pursuant to the California Commercial Code, hereby
pledges all of such Shares (herein sometimes referred to as the "Collateral")
represented by certificate number __, duly endorsed in blank or with executed
stock powers, and herewith delivers said certificate to the Secretary of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

               The pledged stock (together with an executed blank stock
assignment for use in transferring all or a portion of the Shares to Pledgee if,
as and when required pursuant to this Security Agreement) shall be held by the
Pledgeholder as security for the repayment of the Note, and any extensions or
renewals thereof, to be executed by Pledgor pursuant to the terms of the
Agreement, and the Pledgeholder shall not encumber or dispose of such Shares
except in accordance with the provisions of this Security Agreement.



<PAGE>   22

        (2) Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

               (a) Payment of Indebtedness. Pledgor will pay the principal sum
               of the Note secured hereby, together with interest thereon, at
               the time and in the manner provided in the Note.

               (b) Encumbrances. The Shares are free of all other encumbrances,
               defenses and liens, and Pledgor will not further encumber the
               Shares without the prior written consent of Pledgee.

               (c) Margin Regulations. In the event that Pledgee's Common Stock
               is now or later becomes margin-listed by the Federal Reserve
               Board and Pledgee is classified as a "lender" within the meaning
               of the regulations under Part 207 of Title 12 of the Code of
               Federal Regulations ("Regulation G"), Pledgor agrees to cooperate
               with Pledgee in making any amendments to the Note or providing
               any additional collateral as may be necessary to comply with such
               regulations.

        (3) Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

        (4) Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        (5) Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.




                                      -2-
<PAGE>   23

        (6) Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

               a. Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

               b. Pledgor fails to perform any of the covenants set forth in the
Agreement or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

               In the case of an event of Default, as set forth above, Pledgee
shall have the right to accelerate payment of the Note upon notice to Pledgor,
and Pledgee shall thereafter be entitled to pursue its remedies under the
California Commercial Code.

        (7) Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial number of
Shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

        (8) Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

        (9) Term. The within pledge of Shares shall continue until the payment
of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

        (10) Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

        (11) Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

        (12) Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

        (13) Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term

                                      -3-

all purposes, the respective designees, successors, assigns, heirs, executors
and administrators.

        (14) Governing Law. This Security Agreement shall be interpreted and

               IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first above written.

marketable title to its properties and assets, and has good title to all its
leasehold interests, in each case subject to no mortgage, pledge, lien, lease,
encumbrance or charge, other than (i) the lien of current taxes not yet due and
payable, and (ii) possible minor liens and encumbrances which do not in any case
materially detract from the value of the property subject thereto or materially
impair the operations of the Company, and which have not arisen otherwise than
in the ordinary course of business.

        3.7 Patents, Trademarks, etc. The Company owns or has the right to use,
free and clear of all liens, charges, claims and restrictions, all patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses and
proprietary rights necessary to its business as now conducted, and is not
infringing upon or otherwise acting adversely to the right or claimed right of,
to the Company's knowledge, any person under or with respect to any of the
foregoing. There are no outstanding options, licenses, or agreements of any kind
relating to the foregoing, nor is the Company bound by or a party to any
options, licenses or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information, proprietary rights and processes of any other person or entity. The
Company has not received any communications alleging that the Company has
violated or, by conducting its business as currently proposed, would violate any
patent, trademark, service mark, trade name, copyright or trade secret or other
proprietary right of any other person or entity. To the Company's knowledge,
after reasonable investigation, none of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of the Company or that would conflict with the
Company's business as currently proposed to be conducted. Neither the execution
nor delivery of this Agreement, the Shareholders Rights Agreement or the Co-Sale
Agreement, nor the carrying on of the Company's business by the employees of the
Company, nor the conduct of the Company's business as currently proposed to be
conducted, will conflict with or result in a breach of the terms, conditions or
provisions of, or constitute a default under, any contract, covenant or
instrument under which any of such employees is now obligated. The Company does
not believe, after reasonable investigation, that it is or will be necessary to
utilize any inventions of any of the Company's employees (or people it currently
intends to hire) made prior to their employment by the Company.

        3.8 Agreements. There are no agreements, understandings, instruments,
contracts or transactions currently in negotiation, which the Company is a party
that may involve (i) obligations (contingent or otherwise) of, or payments to
the Company in excess of, $10,000, (ii) the license of any patent, copyright,
trade secret or other proprietary right to or from the Company or (iii)
indemnification by the Company with respect to infringements of proprietary
rights.

knowledge of the Company, any third party is in default under any material
contract, agreement or instrument to which the Company is a party.

        3.10 Compliance with Other Instruments, None Burdensome, etc. The
Company is not in violation of any term of its Restated Articles or Bylaws, or
in any material respect of any term or provision of any mortgage, indenture,
contract, agreement, instrument, judgment or decree to which it is a party, and
the Company is not in violation of any federal or state judgment, order,
statute, law, rule or regulation applicable to the Company, which violation
would have a material adverse effect on the Company's business. The execution,
delivery and performance of and compliance with this Agreement, the Shareholder
Rights Agreement and the Co-Sale Agreement and the issuance of the Shares and
the Conversion Shares, will not result in any violation of, or conflict with, or
constitute a default under, any material contract, agreement, instrument or
mortgage, or any pledge, lien, encumbrance or charge upon any of the properties
or assets of the Company; and there is no such violation or default or event
which, with the passage of time or giving of notice or both, would constitute a
violation or default which materially and adversely affects the business of the
Company or any of its properties or assets.

        3.11 Litigation, etc. There are no actions, suits, proceedings or
investigations pending against the Company or its properties before any court or
governmental agency (nor, to the Company's knowledge, is there any threat
thereof or basis therefor), which, either in any case or in the aggregate, would
result in any material adverse change in the business or financial condition of
the Company or any of its properties or assets, or in any material impairment of
the right or ability of the Company to carry on its business as now conducted or
as proposed to be conducted, or in any material liability on the part of the
Company, and none which questions the validity of this Agreement, the
Shareholders Rights Agreement or the Co-Sale Agreement, or any action taken or
to be taken in connection herewith or therewith. The foregoing includes, without
limitation, any action, suit, proceeding, or investigation pending or, to the
Company's knowledge, currently threatened involving the prior employment of any
of the Company's employees, such employees' use in connection with the Company's
business of any information or techniques allegedly proprietary to any of their
former employers, such employees' obligations under any agreements with prior
employers, or negotiations by the Company with potential backers of, or
investors in, the Company or its proposed business. The Company is not a party
to, or to its knowledge, named in any order, writ, injunction, judgment or
decree of any court or government agency or instrumentality. There is no action,
suit or proceeding by the Company currently pending or that the Company
currently intends to initiate.

        3.12 Employees. To the Company's knowledge, no employee of the Company
is in violation of any term of any employment contract, patent disclosure
agreement or any other contract or agreement relating to the relationship of any
such employee with the Company or any other party because of the nature of the
business conducted or to be conducted by the Company. The Company does not have
any collective bargaining agreements covering any of its employees. The
employment of each officer and employee of the Company is terminable at the will
of the Company.

        3.13 Employee Agreements. Each person presently employed by the Company
has executed (or will execute by the Closing Date) an Employment, Confidential
Information and Invention Assignment Agreement in the form previously provided
to or made available to the Purchasers. To the Company's knowledge, neither the
execution, delivery or performance of such agreements, nor the carrying on of
the Company's business as employees by such persons, nor the conduct of the
Company's business as currently proposed will conflict with or result in a
breach of the terms, conditions or provisions of or constitute a default under
any contract, covenant or instrument under which any of such persons is now
obligated.

        3.14 No Conflict of Interest. The Company is not indebted, directly or
indirectly, to any of its officers or directors or to their respective spouses

expenses of employees. To the Company's knowledge, none of the Company's
officers or directors, or any members of their immediate families, are, directly
or indirectly, indebted to the Company (other than in connection with purchases
of the Company's stock) or have any direct or indirect ownership interest in any
firm or corporation with which the Company is affiliated or with which the
Company has a business relationship, or any firm or corporation which competes
with the Company except that officers, directors and/or shareholders of the
Company may own stock in (but not exceeding two percent of the outstanding
capital stock of ) any publicly traded companies that may compete with the
Company. To the Company's knowledge, none of the Company's officers or directors
or any members of their immediate families are, directly or indirectly,

to the Purchasers that, to the best of its knowledge, the Shares should qualify
as "Qualified Small Business Stock" as defined in Section 1202(c) of the

        3.18 Registration Rights. Except as set forth in the Shareholder Rights

the Closing.

        3.20 Permits. The Company has all franchises, permits, licenses, and any

in any material respect under any of such franchises, permits, licenses or other
similar authority.

                                    SECTION 4

                Representations and Warranties of the Purchasers

        Each Purchaser hereby represents and warrants to the Company with
respect to its purchase of the Shares as follows:

        4.1 Investment Representations and Covenants of the Purchasers.

               (a) This Agreement is made by the Company with each Purchaser in
reliance upon such Purchaser's representations and covenants made in this
Section 4, which by its execution of this Agreement each Purchaser hereby
confirms. Each Purchaser represents that the Shares to be received will be
acquired for investment for its own account, not as a nominee or agent, and not
with a view to the sale or distribution of any part thereof, and that it has no
present intention of selling, granting any participation in or otherwise
distributing the same. Each Purchaser further represents that it does not have
any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to any of the Shares or any Common Stock acquired on conversion thereof.

               (b) Each Purchaser understands and acknowledges that the offering
of the Shares pursuant to this Agreement will not, and any issuance of Common
Stock on conversion thereof may not, be registered under the Securities Act on
the ground that the sale provided for in this Agreement and the issuance of
securities hereunder is exempt pursuant to section 4(2) or Section 3(b) of the
Securities Act, and that the Company's reliance on such exemption is predicated
on the Purchasers' representations set forth herein.

               (c) Each Purchaser covenants that in no event will it make any
disposition of any of the Shares, or any Conversion Shares acquired upon the
conversion thereof, except in accordance with Section 4 of the Shareholder
Rights Agreement.

               (d) Each Purchaser represents that it is experienced in
evaluating recently organized, high technology companies such as the Company, is
able to fend for itself in transactions such as the one contemplated by this
Agreement, has such knowledge and experience in financial and business matters
that it is capable of evaluating the merits and risks of its prospective
investment in the Company, and has the ability to bear the economic risks of the
investment.

               (e) Each Purchaser acknowledges and understands that the Shares,
and any Conversion Shares, must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available, and that, except as otherwise provided in the
Shareholder Rights Agreement, the Company is under no obligation to register
either the Shares or Conversion Shares.


                                      -9-


<PAGE>   16

               (f) Each Purchaser acknowledges that it has received and reviewed
a copy of Rule 144 promulgated under the Act, which permits limited public
resales of securities acquired in a non-public offering, subject to the
satisfaction of certain conditions. Each Purchaser understands that before the
Shares, or any Conversion Shares, may be sold under Rule 144, the following
conditions must be fulfilled, except as otherwise described below: (i) certain
public information about the Company must be available, (ii) the sale must occur
at least one year after the later of the date the Shares were sold by the
Company or the date they were sold by an affiliate of the Company, (iii) the
sale must be made in a broker's transaction and (iv) the number of Shares sold
must not exceed certain volume limitations. If, however, the sale occurs at
least two years after the Shares were sold by the Company or an affiliate of the
Company, and if the Purchaser is not an affiliate of the Company, the foregoing
conditions will not apply. Each Purchaser understands that the current
information referred to above is not now available and the Company has no
present plans to make such information available.

               (g) Each Purchaser acknowledges that in the event the applicable
requirements of Rule 144 are not met, registration under the Securities Act or
compliance with another exemption from registration will be required for any
disposition of its stock. Each Purchaser understands that although Rule 144 is
not exclusive, the Commission has expressed its opinion that persons proposing
to sell restricted securities received in a private offering other than in a
registered offering or pursuant to Rule 144 will have a substantial burden of
proof in establishing that an exemption from registration is available for such
offers or sales and that such persons and the brokers who participate in the
transactions do so at their own risk.

               (h) Each Purchaser covenants that, in the absence of an effective
registration statement covering the stock in question, it will sell, transfer,
or otherwise dispose of the Shares and any Conversion Shares only in a manner
consistent with its representations and covenants set forth in this Section 4.
In connection therewith each Purchaser acknowledges that the Company shall make
a notation on its stock books regarding the restrictions on transfer set forth
in this Section 4 and shall transfer shares on the books of the Company only to
the extent not inconsistent therewith.

               (i) Each Purchaser represents that it is an "accredited investor"
as defined in Rule 501 pursuant to the Securities Act.

        4.2 No Public Market. Each Purchaser understands that no public market
now exists for any of the securities issued by the Company and that it is
unlikely that a public market will ever exist for the Shares.

        4.3 Receipt of Information. Each Purchaser has received and reviewed
this Agreement and all Exhibits hereto; it, its attorney and its accountant have
had access to, and an opportunity to review all documents and other materials
requested of, the Company; it and they have been given an opportunity to ask any
and all questions of, and receive answers from, the Company concerning the terms
and conditions of the offering and to evaluate the suitability of an investment

<PAGE>   10

Shareholder Rights Agreement, the Co-Sale Agreement and the Voting Agreement, to

of the Company enforceable in accordance with their respective terms. The

<PAGE>   11

good and marketable title to its properties and assets, and has good title to
all its leasehold interests, in each case subject to no mortgage, pledge, lien,
lease, encumbrance or charge, other than (i) the lien of current taxes not yet
due and payable, and (ii) possible minor liens and encumbrances which do not in
any case materially detract from the value of the property subject thereto or
materially impair the operations of the Company, and which have not arisen
otherwise than in the ordinary course of business.

         3.7      Patents, Trademarks, etc. The Company owns or has the right to
use, free and clear of all liens, charges, claims and restrictions, all patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses and
proprietary rights necessary to its business as now conducted, and is not
infringing upon or otherwise acting adversely to the right or claimed right of,
to the Company's knowledge, any person under or with respect to any of the
foregoing. There are no outstanding options, licenses, or agreements of any kind
relating to the foregoing, nor is the Company bound by or a party to any
options, licenses or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information, proprietary rights and processes of any other person or entity. The
Company has not received any communications alleging that the Company has
violated or, by conducting its business as currently proposed, would violate any
patent, trademark, service mark, trade name, copyright or trade secret or other
proprietary right of any other person or entity. To the Company's knowledge,
after reasonable investigation, none of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of the Company or that would conflict with the
Company's business as currently proposed to be conducted. Neither the execution
nor delivery of this Agreement, the Shareholders Rights Agreement or the Co-Sale
Agreement, nor the carrying on of the Company's business by the employees of the
Company, nor the conduct of the Company's business as currently proposed to be
conducted, will conflict with or result in a breach of the terms, conditions or
provisions of, or constitute a default under, any contract, covenant or
instrument under which any of such employees is now obligated. The Company does
not believe, after reasonable investigation, that it is or will be necessary to
utilize any inventions of any of the Company's employees (or people it currently
intends to hire) made prior to their employment by the Company.

         3.8      Agreements. There are no agreements, understandings,
instruments, contracts or transactions currently in negotiation, which the
Company is a party that may involve (i) obligations (contingent or otherwise)
of, or payments to the Company in excess of, $10,000, (ii) the license of any
patent, copyright, trade secret or other proprietary right to or from the
Company or (iii) indemnification by the Company with respect to infringements of
proprietary rights.

to the knowledge of the Company, any third party is in default under any
material contract, agreement or instrument to which the Company is a party.

         3.10     Compliance with Other Instruments, None Burdensome, etc. The

in any material respect of any term or provision of any mortgage, indenture,
contract, agreement, instrument, judgment or decree to which it is a party, and
the Company is not in violation of any federal or state judgment, order,
statute, law, rule or regulation applicable to the Company, which violation
would have a material adverse effect on the Company's business. The execution,
delivery and performance of and compliance with this Agreement, the Shareholder
Rights Agreement and the Co-Sale Agreement and the issuance of the Shares and
the Conversion Shares, will not result in any violation of, or conflict with, or
constitute a default under, any material contract, agreement, instrument or
mortgage, or any pledge, lien, encumbrance or charge upon any of the properties
or assets of the Company; and there is no such violation or default or event
which, with the passage of time or giving of notice or both, would constitute a
violation or default which materially and adversely affects the business of the
Company or any of its properties or assets.

         3.11     Litigation, etc. There are no actions, suits, proceedings or
investigations pending against the Company or its properties before any court or
governmental agency (nor, to the Company's knowledge, is there any threat
thereof or basis therefor), which, either in any case or in the aggregate, would
result in any material adverse change in the business or financial condition of
the Company or any of its properties or assets, or in any material impairment of
the right or ability of the Company to carry on its business as now conducted or
as proposed to be conducted, or in any material liability on the part of the
Company, and none which questions the validity of this Agreement, the
Shareholders Rights Agreement or the Co-Sale Agreement, or any action taken or
to be taken in connection herewith or therewith. The foregoing includes, without
limitation, any action, suit, proceeding, or investigation pending or, to the
Company's knowledge, currently threatened involving the prior employment of any
of the Company's employees, such employees' use in connection with the Company's
business of any information or techniques allegedly proprietary to any of their
former employers, such employees' obligations under any agreements with prior
employers, or negotiations by the Company with potential backers of, or
investors in, the Company or its proposed business. The Company is not a party
to, or to its knowledge, named in any order, writ, injunction, judgment or
decree of any court or government agency or instrumentality. There is no action,
suit or proceeding by the Company currently pending or that the Company
currently intends to initiate.

         3.12     Employees. To the Company's knowledge, no employee of the
Company is in violation of any term of any employment contract, patent
disclosure agreement or any other contract or agreement relating to the
relationship of any such employee with the Company or any other party because of
the nature of the business conducted or to be conducted by the Company. The
Company does not have any collective bargaining agreements covering any of its
employees. The employment of each officer and employee of the Company is
terminable at the will of the Company.

Company has executed (or will execute by the Closing Date) an Employment,
Confidential Information and Invention Assignment Agreement in the form
previously provided to or made available to the Purchasers. To the Company's
knowledge, neither the execution, delivery or performance of such agreements,
nor the carrying on of the Company's business as employees by such persons, nor
the conduct of the Company's business as currently proposed will conflict with
or result in a breach of the terms, conditions or provisions of or constitute a
default under any contract, covenant or instrument under which any of such
persons is now obligated.

         3.14     No Conflict of Interest. The Company is not indebted, directly
or indirectly, to any of its officers or directors or to their respective

interest in any firm or corporation with which the Company is affiliated or with
which the Company has a business relationship, or any firm or corporation which
competes with the Company except that officers, directors and/or shareholders of
the Company may own stock in (but not exceeding two percent of the outstanding
capital stock of ) any publicly traded companies that may compete with the
Company. To the Company's knowledge, none of the Company's officers or directors

         3.18     Registration Rights. Except as set forth in the Shareholder

the Closing.

         3.20     Permits. The Company has all franchises, permits, licenses,

in any material respect under any of such franchises, permits, licenses or other

                                    SECTION 4

                Representations and Warranties of the Purchasers

         Each Purchaser hereby represents and warrants to the Company with
respect to its purchase of the Shares as follows:

         4.1      Investment Representations and Covenants of the Purchasers.

                  (a) This Agreement is made by the Company with each Purchaser
in reliance upon such Purchaser's representations and covenants made in this
Section 4, which by its execution of this Agreement each Purchaser hereby
confirms. Each Purchaser represents that the Shares to be received will be
acquired for investment for its own account, not as a nominee or agent, and not
with a view to the sale or distribution of any part thereof, and that it has no
present intention of selling, granting any participation in or otherwise
distributing the same. Each Purchaser further represents that it does not have
any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to any of the Shares or any Common Stock acquired on conversion thereof.

                  (b) Each Purchaser understands and acknowledges that the
offering of the Shares pursuant to this Agreement will not, and any issuance of
Common Stock on conversion thereof may not, be registered under the Securities
Act on the ground that the sale provided for in this Agreement and the issuance
of securities hereunder is exempt pursuant to Section 4(2) or Section 3(b) of
the Securities Act, and that the Company's reliance on such exemption is
predicated on the Purchasers' representations set forth herein.

                  (c) Each Purchaser covenants that in no event will it make any
disposition of any of the Shares, or any Conversion Shares acquired upon the
conversion thereof, except in accordance with Section 4 of the Shareholder
Rights Agreement.

                  (d) Each Purchaser represents that it is experienced in
evaluating recently organized, high technology companies such as the Company, is
able to fend for itself in transactions such as the one contemplated by this
Agreement, has such knowledge and experience in financial and business matters
that it is capable of evaluating the merits and risks of its prospective
investment in the Company, and has the ability to bear the economic risks of the
investment.

                  (e) Each Purchaser acknowledges and understands that the
Shares, and any Conversion Shares, must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available, and that, except as otherwise provided in the
Shareholder Rights Agreement, the Company is under no obligation to register
either the Shares or Conversion Shares.



                                      -10-
<PAGE>   16

                  (f) Each Purchaser acknowledges that it has received and
reviewed a copy of Rule 144 promulgated under the Act, which permits limited
public resales of securities acquired in a non-public offering, subject to the
satisfaction of certain conditions. Each Purchaser understands that before the
Shares, or any Conversion Shares, may be sold under Rule 144, the following
conditions must be fulfilled, except as otherwise described below: (i) certain
public information about the Company must be available, (ii) the sale must occur
at least one year after the later of the date the Shares were sold by the
Company or the date they were sold by an affiliate of the Company, (iii) the
sale must be made in a broker's transaction and (iv) the number of Shares sold
must not exceed certain volume limitations. If, however, the sale occurs at
least two years after the Shares were sold by the Company or an affiliate of the
Company, and if the Purchaser is not an affiliate of the Company, the foregoing
conditions will not apply. Each Purchaser understands that the current
information referred to above is not now available and the Company has no
present plans to make such information available.

                  (g) Each Purchaser acknowledges that in the event the
applicable requirements of Rule 144 are not met, registration under the
Securities Act or compliance with another exemption from registration will be
required for any disposition of its stock. Each Purchaser understands that
although Rule 144 is not exclusive, the Commission has expressed its opinion
that persons proposing to sell restricted securities received in a private
offering other than in a registered offering or pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales and that such persons and the brokers who
participate in the transactions do so at their own risk.

                  (h) Each Purchaser covenants that, in the absence of an
effective registration statement covering the stock in question, it will sell,
transfer, or otherwise dispose of the Shares and any Conversion Shares only in a
manner consistent with its representations and covenants set forth in this
Section 4. In connection therewith each Purchaser acknowledges that the Company
shall make a notation on its stock books regarding the restrictions on transfer
set forth in this Section 4 and shall transfer shares on the books of the
Company only to the extent not inconsistent therewith.

                  (i) Each Purchaser represents that it is an "accredited
investor" as defined in Rule 501 pursuant to the Securities Act.

         4.2      No Public Market. Each Purchaser understands that no public
market now exists for any of the securities issued by the Company and that it is
unlikely that a public market will ever exist for the Shares.

         4.3      Receipt of Information. Each Purchaser has received and
reviewed this Agreement and all Exhibits hereto; it, its attorney and its
accountant have had access to, and an opportunity to review all documents and
other materials requested of the Company; it and they have been given an
opportunity to ask any and all questions of, and receive answers from, the
Company concerning the terms and conditions of the offering and to evaluate the
suitability of an investment in the Shares; and, in evaluating the suitability
of an investment in the Shares, it and they have not relied upon any
representations or other information (whether oral or written) other than as set
forth in the documents



                                      -11-
<PAGE>   17

and answers referred to above. The foregoing, however, does not limit or modify
the representations and warranties of the Company in Section 3 of this Agreement
or the right of the Purchasers to rely thereon.

         4.4      Authorization. Each of the Purchasers has the full right,
power and authority to enter into and perform the Purchasers' obligations under
this Agreement, the Shareholder Rights Agreement and the Co-Sale Agreement, and
this Agreement and the Shareholder Rights Agreement and the Co-Sale Agreement
constitute valid and binding obligations of the Purchaser enforceable in
accordance with their terms except (i) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium, and other laws of general application
affecting enforcement of creditor's rights generally, (ii) as limited by laws
relating to the availability of specific performance, injunctive relief or other
equitable remedies and (iii) to the extent that the indemnification provisions
set forth in the Shareholder Rights Agreement may be limited by applicable laws.

         4.5      Consents. No consent, approval or authorization of, or
designation, declaration or filing with, any governmental authority on the part
of the Purchaser is required in connection with the valid execution and delivery
of this Agreement, the Shareholder Rights Agreement or the Co-Sale Agreement.

breach or default, or an acquiescence therein, or of or in any similar breach or
default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring. Any waiver, permit, consent or approval of any kind or

Agreement, or any waiver on the part of any holder of any provisions or
conditions of this Agreement, must be in writing and shall be effective only to

EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, OR SUCH EXEMPTION

as the case may be, is responsible.

         11.10    Counterparts. This Agreement may be executed in any number of
counterparts, each of which may be executed by less than all of the Purchasers,
each of which shall be enforceable against the parties actually executing such

effective if it materially changes the economic benefit of this Agreement to any
party.

marketable title to its properties and assets, and has good title to all its
leasehold interests, in each case subject to no mortgage, pledge, lien, lease,
encumbrance or charge, other than (i) the lien of current taxes not yet due and
payable, and (ii) possible minor liens and encumbrances which do not in any case
materially detract from the value of the property subject thereto or materially
impair the operations of the Company, and which have not arisen otherwise than
in the ordinary course of business.

        3.7 Patents, Trademarks, etc. The Company owns or has the right to use,
free and clear of all liens, charges, claims and restrictions, all patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses and
proprietary rights necessary to its business as now conducted, and is not
infringing upon or otherwise acting adversely to the right or claimed right of,
to the Company's knowledge, any person under or with respect to any of the
foregoing. There are no outstanding options, licenses, or agreements of any kind
relating to the foregoing, nor is the Company bound by or a party to any
options, licenses or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information, proprietary rights and processes of any other person or entity. The
Company has not received any communications alleging that the Company has
violated or, by conducting its business as currently proposed, would violate any
patent, trademark, service mark, trade name, copyright or trade secret or other
proprietary right of any other person or entity. To the Company's knowledge,
after reasonable investigation, none of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of the Company or that would conflict with the
Company's business as currently proposed to be conducted. Neither the execution
nor delivery of this Agreement, the Shareholders Rights Agreement or the Co-Sale
Agreement, nor the carrying on of the Company's business by the employees of the
Company, nor the conduct of the Company's business as currently proposed to be
conducted, will conflict with or result in a breach of the terms, conditions or
provisions of, or constitute a default under, any contract, covenant or
instrument under which any of such employees is now obligated. The Company does
not believe, after reasonable investigation, that it is or will be necessary to
utilize any inventions of any of the Company's employees (or people it currently
intends to hire) made prior to their employment by the Company.

        3.8 Agreements. There are no agreements, understandings, instruments,
contracts or transactions currently in negotiation, which the Company is a party
that may involve (i) obligations (contingent or otherwise) of, or payments to
the Company in excess of, $10,000, (ii) the license of any patent, copyright,
trade secret or other proprietary right to or from the Company or (iii)
indemnification by the Company with respect to infringements of proprietary
rights.

        3.9 Material Contracts and Commitments. Neither the Company, nor, to the
knowledge of the Company, any third party is in default under any material
contract, agreement or instrument to which the Company is a party.

        3.10 Compliance with Other Instruments, None Burdensome, etc. The
Company is not in violation of any term of its Restated Articles or Bylaws, or
in any material respect of any term or provision of any mortgage, indenture,
contract, agreement, instrument, judgment or decree to which it is a party, and
the Company is not in violation of any federal or state judgment, order,
statute, law,


                                      -4-


<PAGE>   9
rule or regulation applicable to the Company, which violation would have a
material adverse effect on the Company's business. The execution, delivery and
performance of and compliance with this Agreement, the Shareholder Rights
Agreement and the Co-Sale Agreement and the issuance of the Shares and the
Conversion Shares, will not result in any violation of, or conflict with, or
constitute a default under, any material contract, agreement, instrument or
mortgage, or any pledge, lien, encumbrance or charge upon any of the properties
or assets of the Company; and there is no such violation or default or event
which, with the passage of time or giving of notice or both, would constitute a
violation or default which materially and adversely affects the business of the
Company or any of its properties or assets.

        3.11 Litigation, etc. There are no actions, suits, proceedings or
investigations pending against the Company or its properties before any court or
governmental agency (nor, to the Company's knowledge, is there any threat
thereof or basis therefor), which, either in any case or in the aggregate, would
result in any material adverse change in the business or financial condition of
the Company or any of its properties or assets, or in any material impairment of
the right or ability of the Company to carry on its business as now conducted or
as proposed to be conducted, or in any material liability on the part of the
Company, and none which questions the validity of this Agreement, the
Shareholders Rights Agreement or the Co-Sale Agreement, or any action taken or
to be taken in connection herewith or therewith. The foregoing includes, without
limitation, any action, suit, proceeding, or investigation pending or, to the
Company's knowledge, currently threatened involving the prior employment of any
of the Company's employees, such employees' use in connection with the Company's
business of any information or techniques allegedly proprietary to any of their
former employers, such employees' obligations under any agreements with prior
employers, or negotiations by the Company with potential backers of, or
investors in, the Company or its proposed business. The Company is not a party
to, or to its knowledge, named in any order, writ, injunction, judgment or
decree of any court or government agency or instrumentality. There is no action,
suit or proceeding by the Company currently pending or that the Company
currently intends to initiate.

        3.12 Employees. To the Company's knowledge, no employee of the Company
is in violation of any term of any employment contract, patent disclosure
agreement or any other contract or agreement relating to the relationship of any
such employee with the Company or any other party because of the nature of the
business conducted or to be conducted by the Company. The Company does not have
any collective bargaining agreements covering any of its employees. The
employment of each officer and employee of the Company is terminable at the will
of the Company.

        3.13 Employee Agreements. Each person presently employed by the Company
has executed (or will execute by the Closing Date) an Employment, Confidential
Information and Invention Assignment Agreement in the form previously provided
to or made available to the Purchasers. To the Company's knowledge, neither the
execution, delivery or performance of such agreements, nor the carrying on of
the Company's business as employees by such persons, nor the conduct of the
Company's business as currently proposed will conflict with or result in a
breach of the terms, conditions or provisions of or constitute a default under
any contract, covenant or instrument under which any of such persons is now
obligated.

        3.14 No Conflict of Interest. The Company is not indebted, directly or
indirectly, to any of its officers or directors or to their respective spouses
or children, in any amount whatsoever other than in connection with expenses or
advances of expenses incurred in the ordinary course of business or relocation
expenses of employees. To the Company's knowledge, none of the Company's
officers or directors, or any members of their immediate families, are, directly
or indirectly, indebted to the Company (other than in connection with purchases
of the Company's stock) or have any direct or indirect ownership interest in any
firm or corporation with which the Company is affiliated or with which the
Company has a business relationship, or any firm or corporation which competes
with the Company except that officers, directors and/or shareholders of the
Company may own stock in (but not exceeding two percent of the outstanding
capital stock of ) any publicly traded companies that may compete with the
Company. To the Company's knowledge, none of the Company's officers or directors
or any members of their immediate families are, directly or indirectly,
interested in any material contract with the Company. The Company is not a
guarantor or indemnitor of any indebtedness of any other person, firm or
corporation.

its unaudited financial statements (balance sheet and statement of operations

(the "Financial Statements"). The Financial Statements have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis throughout the periods indicated and with each other, except that the
unaudited Financial Statements may not contain all footnotes required by
generally accepted accounting principles. The Financial Statements fairly
present the financial condition and operating results of the Company as of the
dates, and for the periods, indicated therein, subject in the case of the
unaudited Financial Statements to normal year-end audit adjustments. Except as
set forth in the Financial Statements, the Company has no material liabilities,
contingent or otherwise, other than (i) liabilities incurred in the ordinary
course of business subsequent to June 30, 1999 and (ii) obligations under
contracts and commitments incurred in the ordinary course of business and not
required under generally accepted accounting principles to be reflected in the
Financial Statements, which, in both cases, individually or in the aggregate,
are not material to the financial condition or operating results of the Company.
Except as disclosed in the Financial Statements, the Company is not a guarantor
or indemnitor of any indebtedness of any other person, firm or corporation. The
Company maintains and will continue to maintain a standard system of accounting
established and administered in accordance with generally accepted accounting
principles.

its business as currently planned to be conducted. The Company is not in default
in any material respect under any of such franchises, permits, licenses or other
similar authority.

Company in this Agreement, or in any written statement or certificate furnished
to the Purchasers pursuant to this Agreement, contains any untrue statement of a
material fact or, when taken together, omits to state a material fact necessary
to make the statements made herein, in light of the circumstances under which
they were made, not misleading. However, as to any projections furnished to the
Purchasers, such projections were prepared in good faith by the Company, but the
Company makes no representation or warranty that it will be able to achieve such
projections. The Company has fully provided each Purchaser with all the
information that such Purchaser has requested for deciding whether to purchase
the Shares.

                                    SECTION 4

                Representations and Warranties of the Purchasers

        Each Purchaser hereby represents and warrants to the Company with
respect to its purchase of the Shares as follows:

        4.1 Investment Representations and Covenants of the Purchasers.

               (a) This Agreement is made by the Company with each Purchaser in
reliance upon such Purchaser's representations and covenants made in this
Section 4, which by its execution of this Agreement each Purchaser hereby
confirms. Each Purchaser represents that the Shares to be received will be
acquired for investment for its own account, not as a nominee or agent, and not
with a view to the sale or distribution of any part thereof, and that it has no
present intention of selling, granting any participation in or otherwise
distributing the same. Each Purchaser further represents that it does not have
any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to any of the Shares or any Common Stock acquired on conversion thereof.

               (b) Each Purchaser understands and acknowledges that the offering
of the Shares pursuant to this Agreement will not, and any issuance of Common
Stock on conversion thereof may not, be registered under the Securities Act on
the ground that the sale provided for in this Agreement and the issuance of
securities hereunder is exempt pursuant to Section 4(2) or Section 3(b) of the
Securities Act, and that the Company's reliance on such exemption is predicated
on the Purchasers' representations set forth herein.

               (c) Each Purchaser covenants that in no event will it make any
disposition of any of the Shares, or any Conversion Shares acquired upon the
conversion thereof, except in accordance with Section 4 of the Shareholder
Rights Agreement.

               (d) Each Purchaser represents that it is experienced in
evaluating recently organized, high technology companies such as the Company, is
able to fend for itself in transactions such as the one contemplated by this
Agreement, has such knowledge and experience in financial and business matters
that it is capable of evaluating the merits and risks of its prospective
investment in the Company, and has the ability to bear the economic risks of the
investment.

               (e) Each Purchaser acknowledges and understands that the Shares,
and any Conversion Shares, must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available, and that, except as otherwise provided in the
Shareholder Rights Agreement, the Company is under no obligation to register
either the Shares or Conversion Shares.

               (f) Each Purchaser acknowledges that it has received and reviewed
a copy of Rule 144 promulgated under the Act, which permits limited public
resales of securities acquired in a


                                      -8-


<PAGE>   13
non-public offering, subject to the satisfaction of certain conditions. Each
Purchaser understands that before the Shares, or any Conversion Shares, may be
sold under Rule 144, the following conditions must be fulfilled, except as
otherwise described below: (i) certain public information about the Company must
be available, (ii) the sale must occur at least one year after the later of the
date the Shares were sold by the Company or the date they were sold by an
affiliate of the Company, (iii) the sale must be made in a broker's transaction
and (iv) the number of Shares sold must not exceed certain volume limitations.
If, however, the sale occurs at least two years after the Shares were sold by
the Company or an affiliate of the Company, and if the Purchaser is not an
affiliate of the Company, the foregoing conditions will not apply. Each
Purchaser understands that the current information referred to above is not now
available and the Company has no present plans to make such information
available.

               (g) Each Purchaser acknowledges that in the event the applicable
requirements of Rule 144 are not met, registration under the Securities Act or
compliance with another exemption from registration will be required for any
disposition of its stock. Each Purchaser understands that although Rule 144 is
not exclusive, the Commission has expressed its opinion that persons proposing
to sell restricted securities received in a private offering other than in a
registered offering or pursuant to Rule 144 will have a substantial burden of
proof in establishing that an exemption from registration is available for such
offers or sales and that such persons and the brokers who participate in the
transactions do so at their own risk.

               (h) Each Purchaser covenants that, in the absence of an effective
registration statement covering the stock in question, it will sell, transfer,
or otherwise dispose of the Shares and any Conversion Shares only in a manner
consistent with its representations and covenants set forth in this Section 4.
In connection therewith each Purchaser acknowledges that the Company shall make
a notation on its stock books regarding the restrictions on transfer set forth
in this Section 4 and shall transfer shares on the books of the Company only to
the extent not inconsistent therewith.

               (i) Each Purchaser represents that it is an "accredited investor"
as defined in Rule 501 pursuant to the Securities Act.

        4.2 No Public Market. Each Purchaser understands that no public market
now exists for any of the securities issued by the Company and that it is
unlikely that a public market will ever exist for the Shares.

        4.3 Receipt of Information. Each Purchaser has received and reviewed
this Agreement and all Exhibits hereto; it, its attorney and its accountant have
had access to, and an opportunity to review all documents and other materials
requested of the Company; it and they have been given an opportunity to ask any
and all questions of, and receive answers from, the Company concerning the terms
and conditions of the offering and to evaluate the suitability of an investment
in the Shares; and, in evaluating the suitability of an investment in the
Shares, it and they have not relied upon any representations or other
information (whether oral or written) other than as set forth in the documents
and answers referred to above. The foregoing, however, does not limit or modify
the representations and warranties of the Company in Section 3 of this Agreement
or the right of the Purchasers to rely thereon.

        4.4 Authorization. Each of the Purchasers has the full right, power and
authority to enter into and perform the Purchasers' obligations under this
Agreement, the Shareholder Rights Agreement and the Co-Sale Agreement, and this
Agreement and the Shareholder Rights Agreement and the Co-Sale Agreement
constitute valid and binding obligations of the Purchaser enforceable in

        7.3 Successors and Assigns. Except as otherwise provided herein, the
provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors, and administrators of the parties hereto,
provided, however, that the rights of a Purchaser to purchase Shares shall not
be assignable without the consent of the Company.

        7.4 Entire Agreement; Amendment. This Agreement and the other documents
delivered pursuant hereto constitute the full and entire understanding and
agreement between the parties with regard to the subjects hereof and thereof.
This Agreement shall supersede and cancel all prior agreements between the
parties hereto with regard to the subject matter hereof, including, but not
limited to, the Prior Purchase Agreement. Neither this Agreement nor any term
hereof may be amended, waived, discharged, or terminated other than by a written
instrument signed by the party against whom enforcement of any such amendment,
waiver, discharge, or termination is sought; provided, however, that holders of
sixty-seven percent (67%) of the shares of Common Stock issued or issuable upon
conversion of the outstanding Shares and (whether or not converted) not resold
to the public may waive or amend, on behalf of all Purchasers, any provisions
hereof, so long as the effect thereof will be that all such Purchasers and other
holders of the Shares will be treated equally.

        7.5 Notices, etc. All notices and other communications required or
permitted hereunder shall be in writing and shall be deemed effectively given
upon delivery to the party to be notified in person by facsimile or by courier
service or five days after deposit with the United States mail, by registered or

Purchaser's address set forth in Exhibit A, or at such other address as such
Purchaser shall have furnished to the Company in writing, or (b) if to any other
holder of any Shares, at such address as such holder shall have furnished the
Company in writing, or, until any such holder so furnishes an address to the
Company, then to and at the address of the last holder of such Shares who has so
furnished an address to the Company, or (c) if to the Company, one copy should
be sent to its address and facsimile number set forth at the end of this
Agreement and addressed to the attention of the Corporate Secretary, or at such
other address as the Company shall have furnished to the Purchasers (with a copy
to Judith M. O'Brien, Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo
Alto, California 94304; facsimile: (650) 493-6811).

        7.6 Delays or Omissions. No delay or omission to exercise any right,
power or remedy accruing to any holder of any Shares, upon any breach or default
of the Company under this Agreement, shall impair any such right, power or
remedy of such holder nor shall it be construed to be a waiver of any such
breach or default, or an acquiescence therein, or of or in any similar breach or
default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring. Any waiver, permit, consent or approval of any kind or
character on the part of any holder of any breach or default under this
Agreement, or any waiver on the part of any holder of any provisions or
conditions of this Agreement, must be in writing and shall be effective only to
the extent specifically set forth in such writing. All remedies, either under
this Agreement or by law or otherwise afforded to any holder, shall be
cumulative and not alternative.

ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE
CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL UNLESS AN
EXEMPTION FROM SUCH QUALIFICATION IS AVAILABLE. THE RIGHTS OF ALL PARTIES TO
THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED,
OR SUCH EXEMPTION BEING AVAILABLE.

        7.8 Expenses. The Company and the Purchasers shall each bear their own
expenses and legal fees with respect to this Agreement and the transactions
contemplated hereby.

        7.9 Finder's Fee. The Company and the Purchasers shall each indemnify
and hold the other harmless from any liability for any commission or
compensation in the nature of a finder's fee (including the costs, expenses and
legal fees of defending against such liability) for which the Company or the
Purchaser's, or any of their respective partners, employees, or representatives,
as the case may be, is responsible.

        7.10 Counterparts. This Agreement may be executed in any number of
counterparts, each of which may be executed by less than all of the Purchasers,
each of which shall be enforceable against the parties actually executing such
counterparts, and all of which together shall constitute one instrument.

        7.11 Severability. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic benefit of this Agreement to any party.

        7.12 Gender. The use of the neuter gender herein shall be deemed to
include the masculine and the feminine gender, if the context so requires.

        7.13 Headings. Headings and the table of contents in this Agreement are

<PAGE>   2

      F. The parties to the Prior Co-Sale Agreement wish to amend, restate and
supersede such agreement and adopt this Co-Sale Agreement in lieu thereof.

      NOW, THEREFORE, in consideration of the mutual covenants set forth herein,
the Purchasers, the Founders and the Company agree as follows:

AGREEMENT

      1.    Definitions

            (a) "Common Stock Equivalents" shall mean the Company's Common Stock
then outstanding and the shares of Common Stock then issuable upon conversion of
all outstanding Preferred Stock, options and other securities convertible into
Common Stock of the Company or convertible into securities convertible into
Common Stock of the Company.

            (b) "Transactions" shall mean any transaction or series of related
transactions which require the giving of notice by a Founder in accordance with
Section 2(a).

            (c) "Participant" shall mean a Purchaser who elects to participate
in a Founder's sale pursuant to Section 2(b) or Section 3(b).

      2.    Sales by a Founder

            (a) Before a Founder attempts to transfer any Co-Sale Shares in one
or more transactions, such Founder shall promptly notify all Purchasers and the
Company of the terms and conditions of the transaction at least twenty (20) days
prior to the proposed closing date of the transaction.

            (b) A Purchaser shall have the right, exercisable upon written
notice to such Founder within ten (10) days after receipt of the Founder's
notice pursuant to Section 2(a), to participate in the Founder's sale of Co-Sale
Shares pursuant to the specified terms and conditions of such Transaction. The
Founder shall have the exclusive right to determine the terms and conditions of
such sale and the Participants participating in any such sale shall each pay a
pro rata share of the reasonable expenses reasonably incurred by the Founder in
connection therewith. In order to participate in the Founder's sale of Common
Stock, a Participant may be required to sell Common Stock in the Transaction
and, accordingly, may be required to convert such Participant's Preferred Stock
into Common Stock immediately prior to the closing of the Transaction. To the
extent one or



                                       2
<PAGE>   3
more of the Purchasers exercise such right of participation in accordance with
the terms and conditions set forth below, the number of shares of Common Stock
which the Founder may sell in the Transaction shall be correspondingly reduced.
The right of participation of each of the Participants shall be subject to the
following terms and conditions.

                     (i) Each of the Participants may sell all or any part of
that number of shares of Common Stock Equivalents of the Company then held by
such Participant equal to the product obtained by multiplying (x) the aggregate
number of shares of Common Stock Equivalents covered by the Transaction by (y) a
fraction, the numerator of which is the number of shares of Common Stock
Equivalents owned by the Participant prior to the Transaction, and the
denominator of which is the aggregate number of shares of Common Stock
Equivalents outstanding prior to the Transaction.

                     (ii) Each of the Participants shall effect its
participation in the sale by delivering to the Founder for transfer to the
purchase offeror one or more certificates, properly endorsed for transfer, which
represent the number of shares of Common Stock Equivalents which the Participant
elects to sell pursuant to this Section 2(b).

            (c) The certificates which the Participants deliver to the Founders
pursuant to Section 2(b) shall be transferred by the Founders to the purchase
offeror in consummation of the Transaction pursuant to the terms and conditions
specified in the Section 2(a) notice to the Participants, and the Founders shall
promptly thereafter remit to each Participant that portion of the sale proceeds
to which the Participant is entitled by reason of its participation in such
sale.

            (d) The exercise or non-exercise of the rights of the Participants
hereunder to participate in one or more Transactions made by the Founders shall
not adversely affect their rights to participate in subsequent Transactions
which satisfy the circumstances specified in Section 2(a).

            (e) The provisions of Section 2(a) shall not apply to (i) any pledge
of Co-Sale Shares made by a Founder which creates a mere security interest,
provided the pledgee shall furnish the Participants with a written agreement
providing that such pledgee shall be bound by and comply with all provisions of
this Co-Sale Agreement applicable to the Founder, (ii) the sale or other
transfer by a Founder or any transferee of a Founder, on a cumulative basis, of
up to 1% of the number of Co-Sale Shares held by such Founder or transferee on
the date of this Agreement in any twelve-month period (as adjusted for stock
splits, stock dividends or other recapitalizations), (iii) any transfer by a
Founder or any transferee or beneficiary of a Founder to his spouse, siblings,
parents or lineal descendants, or a trust or trusts for the benefit of any of
them, provided the transferee or beneficiary shall furnish the Participant with
a written agreement to be bound by and comply with all provisions of this
Agreement applicable to the Founders, (iv) any transfer in connection with (x)
the merger or consolidation of the Company with or into any other corporation or
other entity or person, or any other corporate reorganization in which the
Company shall not be the surviving or continuing entity of such merger,
consolidation or reorganization, so long as such merger, consolidation, or other
corporate reorganization shall have been approved by the Purchasers, or (y) the
sale of all or substantially all of the assets of the Company, (v) any transfer
in connection with an underwritten public offering of the Company's Common Stock
registered under the Securities Act of 1933, as



                                       3
<PAGE>   4
amended, (vi) any sale, assignment or transfer of Co-Sale Shares in connection
with the repurchase of unvested shares of Common Stock by the Company pursuant
to contractual arrangements and (vii) any sale made with the unanimous approval
of the Board of Directors.

      3.    Prohibited Transfers

            (a) In the event a Founder should sell any Co-Sale Shares in
contravention of the participation rights of the Purchasers under this Agreement
(a "Prohibited Transfer"), the Purchasers shall have the put option provided in
Section 3(b) below, and the Founder shall be bound by the applicable provisions
of such put option.

            (b) In the event of a Prohibited Transfer, each Purchaser shall have
the option to sell to the Founder a number of shares of Common Stock Equivalents
of the Company equal (after giving effect to any stock dividends, stock splits
or other recapitalization) to the number of shares such Purchaser would have
been entitled to sell if the Founder had complied with the provisions of Section
2 on the following terms and conditions:

                     (i) The price per share at which the shares are to be sold
to the Founder shall be equal to the price per share paid by the third party
purchaser or purchasers to the Founder.

                     (ii) The Purchaser shall deliver to the Founder, within ten
(10) days after it has received written notice of the Prohibited Transfer, the
certificate or certificates representing shares to be sold, each certificate to
be properly endorsed for transfer.

                     (iii) The Founder shall, upon receipt of the
certificates for the shares subject to the put option, pay the aggregate Section
3(b) purchase price therefor, by certified check or bank draft made payable to
the order of the Participants exercising the Section 3(b) option, and shall
reimburse the Participants for any additional expenses, including legal fees and
expenses, incurred in effecting such purchase and resale.

                     (iv) The parties agree that the foregoing is a liquidated
damages provision, and not a penalty, which is reasonable in light of the
difficulty of determining damages for the breach hereof.

            (c) Notwithstanding the foregoing, any attempt to transfer shares of
the Company in violation of Section 2 hereof shall be void, and the Company
agrees that it will not effect such a transfer nor will it treat any alleged
transferee as the holder of such shares without the written consent of the
number of the Founders and Purchasers having the right to amend this Co-Sale
Agreement as provided below.

      4.    Legended Certificates

            (a) Each certificate representing the Co-Sale Shares now or
hereafter owned by the Founders or any permitted assignee in accordance
herewith, shall be endorsed with the following legend:



                                       4
<PAGE>   5
      "THE SALE OF TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS

THE ORIGINAL OWNER OF THESE SHARES AND CERTAIN SHAREHOLDERS OF THE ISSUER.
COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY
OF THE ISSUER.

            (b) Each Founder hereby agrees to imprint the foregoing legend on
all certificates of Co-Sale Shares now or hereafter in such Founder's possession
and further agrees that the Company may instruct its transfer agent to impose
transfer restrictions on the shares represented by such certificates to enforce
the provisions of this Co-Sale Agreement. Such legend and transfer restrictions
referenced above shall be removed upon termination of this Co-Sale Agreement in
accordance with the provisions of Section 5(a).

      5.    Miscellaneous Provisions

benefit of creditors or the appointment of a receiver or trustee to take
possession of the property and assets of the Company, (iii) the closing of a

covering the offer and sale of securities for the account of the Company to the
public, (iv) the closing of the acquisition of the Company by another entity by
means of merger or consolidation resulting in the exchange of the outstanding

of the assets of the Company. In addition, this Co-Sale Agreement shall

the Securities Exchange Act of 1934, as amended.

            (b) Each Founder represents and warrants that (subject to any

and beneficial owner of the Co-Sale Shares and that no other person has any
interest in such shares.

            (c) All notices required or permitted hereunder shall be in writing
and shall be deemed effectively given upon personal delivery to the party to be
notified or three (3) days after deposit in the United States mail, by
registered or certified mail, postage prepaid and properly addressed to the

address as such party may designate by ten days' advance written notice to the
other parties hereto.

            (d) The rights and obligations of the parties hereunder shall inure
to the benefit of and be binding upon, their respective successors, assigns and
legal representatives.

            (e) In the event one or more of the provisions of this Co-Sale
Agreement should, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity,



                                       5
<PAGE>   6
illegality or unenforceability shall not affect any other provisions of this
Co-Sale Agreement, and this Co-Sale Agreement shall be construed as if such
invalid, illegal or unenforceable provision had never been contained herein.

            (f) Any provision of this Co-Sale Agreement may be amended, waived
or modified only upon the written consent of (i) the Company, (ii) the holders
of a majority of the outstanding shares of the Company's Preferred Stock (or
Common Stock issued upon conversion thereof), acting together as a single class
and (iii) the Founders, provided that any Purchaser may waive any of his rights
hereunder without obtaining the consent of any other Purchaser.

            (g) This Agreement shall be governed by and construed in accordance
with the laws of the State of California.

            (h) In the event of any dispute involving the terms hereof, the
prevailing parties shall be entitled to collect reasonable legal fees and
expenses from the other party(ies) to the dispute.

            (i) This Co-Sale Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

hereof. This Co-Sale Agreement shall supersede and cancel all prior agreements

Agreement of even date herewith (the "SERIES D AGREEMENT") between the Company
and such purchasers (including purchasers in subsequent closings under the

(the "Series D Purchasers") (the Series A Preferred, Series B Preferred, Series
C Preferred and Series D Preferred are collectively referred to herein as the
"Preferred Stock") (the Prior Purchasers and the Series D Purchasers being
collectively referred to herein as the "Purchasers").

        WHEREAS, the Company and Series D Purchasers entered into the Series D
Preferred Purchase Agreement pursuant to which the Company agreed to grant to
Series D Purchasers registration rights upon the terms hereinafter set forth;

        WHEREAS, the Company, the Prior Purchasers have entered into that

(the "PRIOR AGREEMENT");

        WHEREAS, pursuant to Section 24 of the Prior Agreement, the Prior
Agreement may be amended as set forth herein with the Company's prior written
consent and the holders of a majority of the outstanding Registrable Securities
under such Prior Agreement;

        WHEREAS, the parties hereto consisting of the Company, the Founders, the
Prior Purchasers and the Series D Purchasers desire to amend, restate and
supersede in their entirety the Prior Agreement as set forth herein to modify

        NOW, THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, the parties agree as follows:

                                    Agreement

        1. Certain Definitions. As used in this Agreement, the following terms
shall have the following respective meanings:

               "Commission" shall mean the Securities and Exchange Commission or
any successor agency.

<PAGE>   2

               "Registrable Securities" shall mean (i) shares of the Company's
Common Stock issued or issuable upon the conversion of the Series A Preferred,
Series B Preferred, or Series C Preferred or Series D Preferred; (ii) any Common
Stock of the Company or other securities issued or issuable in respect of shares
of the Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred; and (iii) shares of the Company's Common Stock or other securities
issued or issuable with respect to, or in exchange for or in replacement of
shares of the Company's Common Stock issued or issuable upon conversion of the
Series A Preferred, Series B Preferred, Series C Preferred or Series D Preferred
or other securities convertible into or exercisable for the Series A Preferred,
Series B Preferred, Series C Preferred or Series D Preferred upon any stock
split, stock dividend, recapitalization, or similar event; provided, however,
that any shares described in clauses (i)-(iii) above which have been resold to
the public or can be sold pursuant to Rule 144 of the Securities Act (as defined
below) shall cease to be Registrable Securities.

               "Holder" shall mean each Purchaser and any transferee of
Registrable Securities who, pursuant to Section 15 below, is entitled to
registration rights hereunder.

               "Restricted Securities" shall mean the securities of the Company
required to bear the legend set forth in Section 3 hereof (or any similar
legend).

               The terms "register," "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act (as defined below), and the declaration or
ordering of the effectiveness of such registration statement.

               "Registration Expenses" shall mean all expenses incurred by the
Company in complying with Sections 5, 6 and 9 hereof, including, without
limitation, all registration, qualification and filing fees, printing expenses,
escrow fees, fees and disbursements of counsel for the Company, blue sky fees
and expenses, accounting fees of the Company, and the expense of any special
audits incident to or required by any such registration.

               "Securities Act" shall mean the Securities Act of 1933, as
amended.

               "Selling Expenses" shall mean all underwriting discounts, selling
commissions and stock transfer taxes applicable to the securities registered by
the Holders.

        2. Restrictions on Transferability. The Restricted Securities shall not
be transferable except upon the conditions specified in this Agreement, which
conditions are intended to ensure compliance with the provisions of the
Securities Act. Each Holder of Restricted Securities will cause any proposed
transferee of the Restricted Securities held by such Holder to agree to take and
hold such Restricted Securities subject to the provisions and upon the
conditions specified in this Agreement.

        3. Restrictive Legend. Each certificate representing (i) the Series A
Preferred, Series B Preferred, Series C Preferred or Series D Preferred, (ii)
shares of the Company's Common Stock issued upon conversion of the Series A
Preferred, Series B Preferred, Series C Preferred or Series D Preferred, and
(iii) any other securities issued in respect of the Series A Preferred, Series B
Preferred, Series C Preferred or Series D Preferred and Common Stock issued upon
conversion of the Series A Preferred, Series B Preferred, Series C Preferred or
Series D Preferred upon any stock



                                      -2-
<PAGE>   3

split, stock dividend, recapitalization, merger, consolidation or similar event,
shall (unless otherwise permitted by the provisions of Section 4 below) be
stamped or otherwise imprinted with a legend in the following form (in addition
to any legend required under applicable state securities laws):

        THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
        INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
        1933. THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
        REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE
        AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
        TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE
        HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION
        AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

        4. Notice of Proposed Transfers. The Holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Prior to any proposed transfer
of any Restricted Securities (other than (i) a transfer not involving a change
in beneficial ownership, or (ii) in transactions involving the distribution
without consideration of Restricted Securities by a Purchaser to any of its
partners, or retired partners, or to the estate of any of its partners or
retired partners, (iii) a transfer to an affiliated fund or partnership, (iv)
transfers in compliance with Rule 144, so long as the Company is furnished with
satisfactory evidence of compliance with such Rule), unless there is in effect a
registration statement under the Securities Act covering the proposed transfer,
the Holder thereof shall give written notice to the Company of such Holder's
intention to effect such transfer. Each such notice shall describe the manner
and circumstances of the proposed transfer in sufficient detail, and shall, if
the Company so requests, be accompanied (except in transactions in compliance
with Rule 144) by either (i) an unqualified written opinion of legal counsel who
shall be reasonably satisfactory to the Company, addressed to the Company and
reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act, or (ii) a "no action" letter from
the Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company. Each certificate evidencing the Restricted Securities transferred as
above provided shall bear the appropriate restrictive legend set forth in
Section 3 above, except that such certificate shall not bear such restrictive
legend if in the opinion of counsel for the Company such legend is not required
in order to establish compliance with any provisions of the Securities Act.

        5.     Requested Registration.

                  (a) Request for Registration. If at any time after the earlier
of (i) five years from September 14, 1999 or (ii) six months after the closing
date of the first registration statement filed by the Company covering an
underwritten offering of any of its securities to the general public, the
Company shall receive from any Holder or group of Holders holding at least a
majority of the Registrable Securities (the "Initiating Holders") a written
request that the Company effect any



                                      -3-
<PAGE>   4

registration, qualification or compliance with respect to at least thirty
percent (30%) of the shares of Registrable Securities, or such lesser number of
shares of Registrable Securities if the reasonably anticipated aggregate
proceeds of such offering exceed $15,000,000, the Company will:

                      (x) promptly give written notice of the proposed
registration, qualification or compliance to all other Holders holding
Registrable Securities; and

                      (y) as soon as practicable, use its best efforts to effect
such registration, qualification or compliance (including, without limitation,
the execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act and any other governmental requirements or regulations) as may be so
requested and as would permit or facilitate the sale and distribution of all or
such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within 20 days after receipt of such written notice from the
Company;

               Provided, however, that the Company shall not be obligated to
take any action to effect any such registration, qualification or compliance
pursuant to this Section 5:

                             (A) In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                             (B) After the Company has effected two such
registrations pursuant to this Section 5(a), such registrations have been
declared or ordered effective and the securities offered pursuant to such
registrations have been sold; or

                             (C) Within six months following the effective date
of a registration statement previously filed by the Company.

        Subject to the foregoing clauses (A), (B) and (C), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Initiating Holders. If, however, the Company shall furnish to the
Initiating Holders a certificate signed by the President of the Company stating
that, in the good faith judgment of the Board of Directors of the Company, it
would be seriously detrimental to the Company and its shareholders for such
registration statement to be filed and it is therefore essential to defer the
filing of such registration statement, the Company shall have the right to defer
such filing for a period of not more than 120 days after receipt of the request
of the Initiating Holder, provided, however, that the Company may not utilize
this right more than once in any twelve-month period.

                  (b) Underwriting. If the Initiating Holders intend to
distribute the Registrable Securities covered by their request by means of an
underwriting, they shall so advise the Company as a part of their request made
pursuant to Section 5(a) and the Company shall include such information in the
written notice referred to in Section 5(a)(x). The right of any Holder to



                                      -4-
<PAGE>   5

registration pursuant to Section 5 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent requested (unless
otherwise mutually agreed by a majority in interest of the Holders) and to the
extent provided herein.

        The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by a majority in interest of the Initiating Holders. Notwithstanding any other
provision of this Section 5, if the managing underwriter advises the Initiating
Holders in writing that marketing factors require a limitation of the number of
shares to be underwritten, then, subject to the provisions of Section 5(a), the
Company shall so advise all Holders and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among all Holders requesting inclusion in the registration in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities held by such Holders at the time of filing the registration
statement. No Registrable Securities excluded from the underwriting by reason of
the managing underwriter's marketing limitation shall be included in such
registration.

        If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the other Holders. The Registrable
Securities and/or other securities so withdrawn shall also be withdrawn from
registration; provided, however, that if by the withdrawal of such Registrable
Securities a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the maximum of any limitation imposed by
the underwriters), then the Company may offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used in determining the
underwriter limitation in this Section 5(b). If the registration does not become
effective due to the withdrawal of Registrable Securities, then either (1) the
Holders requesting registration shall reimburse the Company for expenses
incurred in complying with the request or (2) the aborted registration shall be
treated as effected for purposes of Section 5(a)(B).

        6.     Company Registration.

                  (a) Notice of Registration. If the Company shall determine to
register any of its securities, either for its own account or the account of a
security holder or holders exercising their respective requested registration
rights, other than (i) a registration relating solely to employee benefit plans,
(ii) a registration relating solely to a transaction pursuant to Rule 145 of the
Securities Act, or (iii) a registration on Form S-3 solely for the purpose of
registering shares issued in a non-underwritten offering in connection with a
merger, combination or acquisition, the Company will:

                      (i) promptly give to each Holder written notice thereof;
and

                      (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 20 days after receipt of such written notice from the
Company, by any Holder or Holders.



                                      -5-
<PAGE>   6

                  (b) Underwriting. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 6(a)(i). In such event, the right of any Holder to
registration pursuant to Section 6 shall be conditioned upon such Holder's
participation in such underwriting to the extent provided herein. The Company
shall (together with all Holders proposing to distribute their securities
through such underwriting) enter into an underwriting agreement in customary
form with the managing underwriter selected for such underwriting by the
Company. Notwithstanding any other provision of this Section 6, if the managing
underwriter determines that marketing factors require a limitation of the number
of shares to be underwritten, the managing underwriter may limit the Registrable
Securities and other securities to be distributed through such underwriting,
provided that the Company may limit, to the extent so advised by the
underwriters, the amount of Registrable Securities to be included in the
registration by the Holders to an amount not less than 30% of the total number
of securities included in the offering, unless such offering is the initial
public offering of the Company's securities, in which case all Registrable
Securities may be excluded from such offering. No Registrable Securities
excluded from the underwriting by reason of the managing underwriter's marketing
limitation shall be included in such registration.

        If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the other Holders. The Registrable
Securities and/or other securities so withdrawn shall also be withdrawn from
registration; provided, however, that if by the withdrawal of such Registrable
Securities a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the maximum of any limitation imposed by
the underwriters), then the Company may offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used in determining the
underwriter limitation in this Section 6(b).

                  (c) In all registered public offerings, whether underwritten
or not, the amount of Registrable Securities of Holders which are included in
such registration, in accordance with the limitations set forth in Section
6(a)(ii) above, shall be allocated to the Holders in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities which would be
held by each of such Holders assuming conversion of all outstanding Series A
Preferred, Series B Preferred and Series C Preferred as of the date of the
notice given pursuant to this Section 6.

        7. Expenses of Registration. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Section 5(a), Section 6 and Section 9 shall be borne by the Company. All Selling
Expenses relating to securities registered by the Holders shall be borne by the
Holders of such securities pro rata on the basis of the number of shares so
registered.

        8. Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

                  (a) Prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least 120 days or
until the distribution described in the registration statement has been



                                      -6-
<PAGE>   7

completed; provided, however, that such one 120-day period shall be extended for
a period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company;

                  (b) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement;

                  (c) Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable
number of copies of the registration statement, preliminary prospectus, final
prospectus and such other documents as such underwriters may reasonably request
in order to facilitate the public offering of such securities;

                  (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement;

                  (f) Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of material fact or omits to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing;

                  (g) Cause such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed; and

                  (h) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

        9. Registration on Form S-3. In addition to the rights set forth in
Section 5, if the Holders holding at least 30% of the Registrable Securities
request in writing that the Company file a registration statement on Form S-3
(or any successor thereto) for a public offering of shares of Registrable
Securities the reasonably anticipated aggregate price to the public of which
would exceed $1,000,000, and the Company is a registrant entitled to use Form
S-3 to register securities for such an offering, the Company shall use its best
efforts to cause such shares to be registered for the offering on such form (or
any successor thereto). The Company will promptly give written notice of



                                      -7-
<PAGE>   8

the request for the proposed registration to all other Holders and include all
Registrable Securities of any Holder or Holders joining in such request as are
specified in a written request received by the Company within 30 days after
receipt of such written notice from the Company. The substantive provisions of
Section 5(b) shall be applicable to each registration initiated under this
Section 9. A Holder or group of Holders is entitled to an unlimited number of
Form S-3 registrations; provided, however, that the Company shall be required to
file no more than one (1) such registration statement during any 12-month
period.

        10. Termination of Registration Rights. The registration rights granted
pursuant to this Agreement shall terminate (i) as to all Holders on the fifth
anniversary of the closing of the Company's initial public offering and (ii) as
to any Holder, at such time after the Company's initial public offering as the
Registrable Securities held by such Holder represents 1% or less of the
outstanding Common Stock of the Company and such Holder is able to sell such
Registrable Securities under Rule 144 or such Holder is able to sell all
Registrable Securities held by it pursuant to Rule 144(k) promulgated under the
Securities Act.

        11. Lockup Agreement. In consideration for the Company agreeing to its
obligations under this Agreement each Holder of Registrable Securities and each
transferee pursuant to Section 15 hereof agrees, in connection with the first
registration of the Company's securities, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Registrable Securities or other securities of the
Company (other than those included in the registration) without the prior
written consent of the Company or such underwriters, as the case may be, for
such period of time (not to exceed 180 days) from the effective date of such
registration as the Company or the underwriters may specify; provided, however
that all executive officers and directors of the Company must enter into similar
Lock-Up Agreements as well. Each Holder agrees that the Company may instruct its
transfer agent to place stop transfer notations in its records to enforce the
provisions of this Section 11.

        12.    Indemnification.

                  (a) The Company will indemnify each Holder, each of its
officers, directors and partners and such Holder's legal counsel and independent
accountants, and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Agreement, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, arising out of or
based on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, not misleading, or any violation by
the Company of any rule or regulation promulgated under the Securities Act
applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, qualification or compliance,
and will reimburse each such Holder, each of its officers, directors and
partners and



                                      -8-
<PAGE>   9

such Holder's legal counsel and independent accountants, and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder or underwriter and stated to be specifically for use therein.

                  (b) Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers and its legal counsel and independent accountants,
each underwriter, if any, of the Company's securities covered by such a
registration statement, each person who controls the Company or such underwriter
within the meaning of Section 15 of the Securities Act, and each other such
Holder, each of its officers and directors and each person controlling such
Holder within the meaning of Section 15 of the Securities Act, against all
claims, losses, damages and liabilities (or actions in respect thereof) arising
out of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any such registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company, such Holders,
such directors, officers, legal counsel, independent accountants, underwriters
or control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder and
stated to be specifically for use therein; provided, however, that the
obligations of such Holders hereunder shall be limited to an amount equal to the
gross proceeds before expenses and commissions to each such Holder of
Registrable Securities sold as contemplated herein.

                  (c) Each party entitled to indemnification under this Section
12 (the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense; provided, however, that the Indemnified Party (together with
all other Indemnified Parties that may be represented without conflict by one
counsel) shall have the right to retain one separate counsel, with the fees and
expenses to be paid by the Indemnifying Party, if representation of such
Indemnified Party by the counsel retained by the Indemnifying Party would be
inappropriate due to actual or potential differing interests between such
Indemnified Party and any other party represented by such counsel in such
proceeding; and provided further that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Agreement, except to the extent, but only to the extent,
that the



                                      -9-
<PAGE>   10

Indemnifying Party's ability to defend against such claim or litigation is
impaired as a result of such failure to give notice. No Indemnifying Party, in
the defense of any such claim or litigation, shall, except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation.

        13. Information by Holder. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Agreement.

        14. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to:

                  (a) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date of the first registration under the Securities Act
filed by the Company for an offering of its securities to the general public;

                  (b) Use its best efforts to then file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Securities Exchange Act of 1934, as amended (at any time
after it has become subject to such reporting requirements); and

                  (c) Furnish to Holders of Registrable Securities forthwith
upon request, a written statement by the Company as to its compliance with the
reporting requirements of Rule 144 (at any time after 90 days after the
effective date of the first registration statement filed by the Company for an
offering of its securities to the general public), and of the Securities Act and
the Securities Exchange Act of 1934 (at any time after it has become subject to
such reporting requirements), a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents of the Company as a
Holder of Registrable Securities may reasonably request in availing itself of
any rule or regulation of the Commission allowing such Holder to sell any such
securities without registration.

        15. Transfer of Registration Rights. The right to cause the Company to
register securities granted hereunder may be assigned to a transferee or
assignee who acquires at least 500,000 shares of Series A Preferred, Series B
Preferred, Series C Preferred or Series D Preferred (or Common Stock issued on
conversion thereof) (as adjusted for stock splits, reverse stock splits or
similar events after the date hereof), provided that the Company is given
written notice of such assignment prior to such assignment. In addition, rights
to cause the Company to register securities may be freely assigned (a) to any
constituent partner or retired partner of a Holder, where such Holder is a
partnership, (b) to any affiliate (as that term is defined in Rule 405
promulgated by the Commission under the Securities Act), (c) to any officer,
director or principal shareholder thereof, where such Holder is a corporation or
(d) to the spouse, children, grandchildren or spouse of such children or



                                      -10-
<PAGE>   11

grandchildren of any Holder or to trusts for the benefit of any Holder or such
persons where the Holder is a natural person.

        16. Subsequent Grant of Registration Rights. The Company shall not grant
rights to have securities other than the Registrable Securities registered under
the Securities Act that are pari passu or superior to the registration rights
granted herein without the written consent of the holders of a majority of the
shares of Series A Preferred, Series B Preferred, Series C Preferred and Series
D Preferred (or Common Stock issued upon conversion thereof) (voting together as
a single class on an as converted basis).

        17. Company Covenants. The Company hereby covenants and agrees as
follows:

               17.1 Annual Financial Information. The Company will furnish to
each Purchaser for so long as such Purchaser is a holder of any shares of Series
A Preferred, Series B Preferred, Series C Preferred or Series D Preferred
purchased by such person pursuant to the Agreement (or Common Stock issued upon
conversion of the Series A Preferred, Series B Preferred, Series C Preferred or
Series D Preferred), as soon as practicable after the end of each fiscal year,
and in any event within 90 days thereafter, consolidated balance sheets of the
Company and its subsidiaries, if any, as of the end of such fiscal year, and
consolidated statements of income and consolidated statements of cash flows of
the Company and its subsidiaries, if any, for such year, prepared in accordance
with generally accepted accounting principles consistently applied and setting
forth in each case in comparative form the figures for the previous fiscal year,
all in reasonable detail and certified by independent public accountants of
national standing selected by the Company.

               17.2 Quarterly Financial Information and Financial Plan. The
Company will furnish the following reports to each Purchaser for so long as such
Purchaser is a holder of at least 500,000 shares of Series A Preferred, Series B
Preferred, Series C Preferred or Series D Preferred (or Common Stock issued upon
conversion of Series A Preferred, Series B Preferred, Series C Preferred or
Series D Preferred or a combination of such Series A Preferred, Series B
Preferred, Series C Preferred and Common Stock) (adjusted for stock splits,
reverse stock splits or similar events after the date hereof).

                  (a) As soon as practicable after the end of each fiscal
quarter (except for the fiscal quarter ending December 31 of each year), and in
any event with 45 days thereafter, consolidated balance sheets of the Company
and its subsidiaries, if any, as of the end of such quarter, and cash flow
statements and consolidated statements of income for each quarter and for the
current fiscal year to date, prepared in accordance with generally accepted
accounting principles consistently applied, all in reasonable detail and signed,
subject to changes resulting from year-end audit adjustments, by the principal
financial or accounting officer of the Company, together with a comparison of
such statements to the Company's operating plan then in effect and approved by
its Board of Directors.

                  (b) As soon as available (but in any event within 10 days
after the commencement of its fiscal year), a summary of the financial plan of
the Company for each fiscal year, including (but not limited to) a cash flow
projection and operating budget, calculated monthly, as contained in its
operating plan approved by the Company's Board of Directors.



                                      -11-
<PAGE>   12

               17.3 Assignment of Rights to Financial Information. The rights to
receive information pursuant to Section 17.1 may be assigned or otherwise
conveyed by any Purchaser or subsequent transferee to any transferee of shares
of Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred (or Common Stock issued upon conversion thereof). The rights specified
in Section 17.2 may be assigned or otherwise conveyed by a Purchaser or
subsequent transferee only to a transferee who acquires at least 500,000 shares
of Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred (or Common Stock issued upon conversion thereof) (adjusted for stock
splits, reverse stock splits or similar events after the date hereof).

               17.4 Inspection. The Company shall permit each Purchaser for so
long as such Purchaser is eligible to receive reports under Section 17.2 at such
Purchaser's expense, to visit and inspect the Company's properties, to examine
its books of account and records and to discuss the Company's affairs, finances
and accounts with its officers, all at such reasonable times as may be requested
by the Purchaser; provided, however, that the Company shall not be obligated
pursuant to this Section 17.4 to provide access to any information which it
reasonably considers to be a trade secret or similar confidential information.

               17.5 Employment, Confidential Information and Invention
Assignment Agreement. The Company will require each person employed by the
Company, whether at present or in the future, to execute an Employment,
Confidential Information and Invention Assignment Agreement in a form approved
by the Company's Board of Directors as a condition of such employment.

               17.6 Vesting of Employee Stock. All stock and options to acquire
stock of the Company granted to employees of the Company pursuant to a stock
grant, option plan or purchase plan or other employee stock incentive program
approved by the Board of Directors will be subject to four year vesting, except
as otherwise approved by the Company's Board of Directors.

               17.7 Confidentiality Agreement. Each Purchaser and any successor
or assign of such Purchaser, who receives from the Company or its agents,
directly or indirectly, any information which the Company has not made generally
available to the public, pursuant to the preparation and execution of this
Agreement or disclosure in connection therewith or pursuant to the provisions of
this Section 17, acknowledges and agrees that such information is confidential
and for its use only in connection with evaluating its investment in the
Company, and further agrees that it will not disseminate such information to any
person other than its accountant, investment advisor or attorney and that such
dissemination shall be only for purposes of evaluating its investment.

               17.8 Termination of Covenants. Notwithstanding anything to the
contrary set forth herein, the covenants set forth in this Section 17 shall
terminate and be of no further force or effect after the date upon which the
first registration statement filed by the Company under the Securities Act in
connection with an underwritten public offering of its securities first becomes
effective ("IPO").

        18. Rights of First Refusal. The Company hereby grants to each Purchaser
who holds at least 600,000 shares of Registrable Securities the right of first
refusal to purchase its pro rata share of "New Securities" (as defined in this
Section 18) that the Company may, from time to time propose to sell and issue.
Such pro rata share, for purposes of this right of first refusal, is the ratio
of (X) the number of shares of Common Stock immediately prior to the issuances
of New Securities then


                                      -12-
<PAGE>   13
owned by such Purchaser or issuable upon the conversion of the Series A
Preferred, Series B Preferred, Series C Preferred or Series D Preferred then
owned by such Purchaser (including shares issuable upon exercise of options or
warrants held by such Purchaser), to (Y) the total number of shares of Common
Stock immediately prior to the issuances of New Securities then outstanding,
after giving effect to the conversion of all outstanding convertible securities
(including the Series A Preferred Stock, Series B Preferred, Series C Preferred
and Series D Preferred) and the exercise of all outstanding options. This right
of first refusal shall be subject to the following provisions:

                  (a) "New Securities" shall mean any Common Stock and Preferred
Stock of the Company whether or not authorized on the date hereof, and rights,
options, or warrants to purchase Common Stock or Preferred Stock and securities
of any type whatsoever that are, or may become, convertible into Common Stock or
Preferred Stock; provided, however, that "New Securities" does not include the
following:

                      (i) the Series A Preferred, the Series B Preferred, the
Series C Preferred or any agreement or commitment to issue any of the foregoing;

                      (ii) shares of Common Stock, or options to purchase shares
of Common Stock (including all options granted by the Company prior to the date
of this Agreement), issued or granted to officers, directors and employees of,
or consultants to, the Company pursuant to a stock grant, employee restricted
stock purchase agreement, option plan or purchase plan or other stock incentive
program (collectively, the "Plans");

                      (iii) shares of Common Stock issuable upon conversion of
the Series A Preferred, Series B Preferred and Series C Preferred;

                      (iv) securities of the Company offered to the public
pursuant to a firm commitment underwritten public offering pursuant to a
registration statement filed under the Securities Act;

                      (v) securities of the Company issued pursuant to the
acquisition of another corporation by the Company by merger, purchase of
substantially all of the assets, or other reorganization whereby the Company
owns more than fifty percent (50%) of the voting power of such other
corporation;

                      (vi) securities of the Company issued in connection with
equipment lease financing transactions, real estate leases or bank financing
transactions the principal purpose of which is not to raise equity funding;

                      (vii) securities issued to corporate partners or in
connection with other strategic alliances if the Board of Directors agrees that
such transaction should be excluded from operation of this Section 18; and

                      (viii) shares of Common Stock or Preferred Stock issued in
connection with any stock split, stock dividend, or recapitalization by the
Company.



                                      -13-
<PAGE>   14

                  (b) In the event that Company proposes to undertake an
issuance of New Securities, it shall give each Purchaser written notice of its
intention, describing the type of New Securities, the price, and the general
terms upon which the Company proposes to issue the same. Each Purchaser shall
have twenty (20) business days after receipt of such notice to agree to purchase
its pro rata share of such New Securities at the price and upon the terms
specified in the notice by giving written notice to the Company and stating
therein the quantity of New Securities to be purchased. If any Purchaser fails
to agree to purchase its full pro rata share within such twenty (20) business
day period, the Company shall give the Purchasers who did so agree (the
"Electing Purchasers") notice of the number of shares which were not subscribed
for. Such notice may be by telephone if followed by written confirmation within
two days. The Electing Purchasers shall have five (5) business days from the
date of such notice to agree to purchase their pro rata share of all of the New
Securities not purchased by such non-purchasing Purchasers.

                  (c) In the event that Purchasers fail to exercise in full the
right of first refusal within the twenty (20) business day plus five (5)
business day period specified above, the Company shall have one hundred twenty
(120) days thereafter to sell (or enter into an agreement pursuant to which the
sale of New Securities covered thereby shall be closed, if at all, within sixty
(60) days from the date of said agreement) the New Securities respecting which
the rights of the Purchasers were not exercised at a price and upon terms no
more favorable to the purchasers thereof than specified in the Company's notice.
In the event the Company has not sold the New Securities within such one hundred
twenty (120) day period (or sold and issued New Securities in accordance with
the foregoing within sixty (60) days from the date of such agreement) the
Company shall not thereafter issue or sell any New Securities, without first
offering such New Securities to the Purchasers and in the manner provided above.

                  (d) The right of first refusal granted under this Section 18
shall expire upon an IPO.

                  (e) This right of first refusal is nonassignable except to any
transferee to whom registration rights may be transferred pursuant to Section 15
of this Agreement.

        19. Governing Law. This Agreement and the legal relations between the
parties arising hereunder shall be governed by and interpreted in accordance
with the laws of the State of California. The parties hereto agree to submit to
the jurisdiction of the federal and state courts of the State of California with
respect to the breach or interpretation of this Agreement or the enforcement of
any and all rights, duties, liabilities, obligations, powers, and other
relations between the parties arising under this Agreement.

        20. Entire Agreement. This Agreement constitutes the full and entire
understanding and agreement between the parties regarding rights to
registration. Except as otherwise expressly provided herein, the provisions
hereof shall inure to the benefit of, and be binding upon, the successors,
assigns, heirs, executors and administrators of the parties hereto. This
Agreement shall supersede and cancel all prior agreements between the parties
hereto with regard to the subject matter hereof, including, but not limited to,
the Prior Rights Agreement.

upon delivery to the party to be notified in person by facsimile or by courier
service or five days after deposit with the United States mail, by registered or
certified mail, postage prepaid, addressed (a) if to a Purchaser, at such

Company, then to and at the address of the last holder of such Shares who has so
furnished an address to the Company, or (c) if to the Company, one copy should
be sent to its address and facsimile number set forth at the end of this
Agreement and addressed to the attention of the Corporate Secretary, or at such

        22. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

        23. Additional Parties. The parties to this Agreement acknowledge that
the Company's Preferred Stock may be sold in multiple closings pursuant to the
Purchase Agreement, and the parties hereto agree that all of the purchasers of
Preferred Stock pursuant to the Purchase Agreement can be added as parties to
this Agreement and granted all of the rights of Purchasers under this Agreement
without any further action or approval by other parties to this Agreement.

        24. Amendment. Any provision of this Agreement may be amended, waived or
modified upon the written consent of the Company and the Holders of a majority
of the Registrable Securities. Any amendment or waiver effected in accordance
with this Section shall be binding upon each Holder of Registrable Securities
and the Company. Any Purchaser may waive any of its rights or the Company's
obligations hereunder without obtaining the consent of any other person.

        25. Headings. Headings and the table of contents in this Agreement are

hereunder, the amount from time to time outstanding, the applicable interest
rate in respect of each Loan, and the amount and date of any repayment
hereunder, shall be noted on Bank's books and records, which shall be conclusive

                                       9
<PAGE>   11

        3.3 Payments on Non-Business Day. In the event that any payment of any
principal, interest, fees or any other amounts payable by Borrower under or
pursuant to this Agreement, or under any other Loan Document shall become due on
any day which is not a Business Day, such due date shall be extended to the next
succeeding Business Day, and, to the extent applicable, interest shall continue
to accrue and be payable at the applicable rate(s) for and during any such
extension.

        3.4 Payment Procedures. All sums payable by Borrower to Bank under or
pursuant to this Agreement, or any other Loan Document, whether principal,
interest, or otherwise, shall be paid, when due, directly to Bank at the office
of Bank identified on the signature page of this Agreement, or at such other
office of Bank as Bank may designate in writing to Borrower from time to time,
in immediately available United States funds, and without setoff, deduction or
counterclaim. Bank may, in its discretion, charge any and all deposit or other
accounts (including, without limitation, any account evidenced by a certificate
of deposit or time deposit) of Borrower maintained with Bank for all or any part
of any Indebtedness then due and payable; provided, however, that such
authorization shall not affect Borrower's obligations to pay all Indebtedness,
when due, whether or not any such account balances maintained by Borrower with
Bank are insufficient to pay any amounts then due.

        3.5 Default Rate. Notwithstanding anything to the contrary set forth
herein, in the event that and so long as any Event of Default shall have
occurred and be continuing or exist, all Indebtedness outstanding shall bear
interest at a rate equal to the then applicable interest rate plus three percent
(3%), which interest, in any case, shall be payable upon demand.

        3.6 Receipt of Payments by Bank. Any payment by Borrower of any of the
Indebtedness made by mail will be deemed tendered and received by Bank only upon
actual receipt thereof by Bank at the address designated for such payment,
whether or not Bank has authorized payment by mail or in any other manner, and
such payment shall not be deemed to have been made in a timely manner unless
actually received by Bank on or before the date due for such payment, time being
of the essence. Borrower expressly assumes all risks of loss or liability
resulting from non-delivery or delay of delivery of any item of payment
transmitted by mail or in any other manner. Acceptance by Bank of any payment in
an amount less than the amount then due shall be deemed an acceptance on account
only, and any failure to pay the entire amount then due shall constitute and
continue to be an Event of Default hereunder, and at any time thereafter, and
until the entire amount then due has been paid in full, Bank shall be entitled
to exercise any and all rights and remedies conferred upon and otherwise
available to Bank hereunder or any of the other Loan Documents upon the
occurrence and during the continuance of any such Event of Default. Prior to the
occurrence of any Event of Default hereunder, Borrower shall have the right to
direct the application of any and all payments made to Bank by Borrower
hereunder to the respective Indebtedness. Borrower waives the right to direct
the application of any and all payments received by Bank from and on behalf of
Borrower at any time or times after the occurrence and during the continuance of
any Event of Default hereunder. Borrower further agrees that after the
occurrence and during the continuance of any Event of Default hereunder, or
prior to the occurrence of any Event of Default hereunder if Borrower has failed
to direct such application, Bank shall have the continuing exclusive right to
apply and to reapply any and all payments received by Bank at any time or times
hereafter, whether as voluntary payments, proceeds from any Collateral, offsets,
or otherwise, against the Indebtedness in such order and in such manner as Bank
may, in its sole discretion, deem advisable, notwithstanding any entry by Bank
upon any of its books and records. Borrower hereby expressly agrees that, to the
extent that Bank receives any payment or benefit of or otherwise upon any of the
Indebtedness, and such payment or benefit, or any part thereof, is subsequently
invalidated, declared to be fraudulent or preferential, set aside, or required
to be repaid to a trustee, receiver, or any other party under any bankruptcy
act, state or federal law, common law, or equitable cause, then to the extent of
such payment or benefit, the Indebtedness, or part thereof, intended to be
satisfied shall be revived and continued in full force and effect as if such
payment or benefit had not been made by Borrower or received by Bank, and,
further, any such repayment by Bank shall be added to and be deemed to be
additional Indebtedness.

SECTION 4: CREATION OF SECURITY INTEREST

        4.1 Grant of Security Interest. Borrower grants and pledges to Bank a
continuing security interest in all presently existing and hereafter acquired or
arising Collateral in order to secure prompt payment of any and all Indebtedness
and in order to secure prompt performance by Borrower of each of its covenants
and duties under the Loan Documents. Except for Permitted Liens, such security
interest constitutes a valid, first priority security interest


                                       10
<PAGE>   12

in the presently existing Collateral, and will constitute a valid, first
priority security interest in Collateral acquired after the date hereof, in each
case, to the extent that a security interest in such Collateral can be perfected
by the filing of a financing statement or, in the case of Collateral consisting
of instruments, documents, chattel paper or certificated securities, to the
extent that Bank takes possession of such Collateral. Borrower acknowledges that
Bank may place a "hold" on any deposit account pledged as Collateral to secure
the Indebtedness. Bank agrees to execute and deliver to Borrower from time to
time such subordination agreements as Borrower may request and as are necessary
to give to other lenders which finance equipment for Borrower a first priority
security interest in the equipment financed so long as the Liens and the
Indebtedness incurred with respect to such equipment financing are permitted
under this Agreement. Notwithstanding the foregoing, the security interest
granted herein shall not extend to and the term "Collateral" shall not include
any property, rights or licenses to the extent the granting of a security
interest therein (i) would be contrary to applicable law or (ii) is prohibited
by or would constitute a default under any agreement or document governing such
property, rights or licenses (but only to the extent such prohibition is
enforceable under applicable law, including without limitation Section 9318 of
the Code); provided that immediately and automatically upon the ineffectiveness,
lapse or termination of any such prohibition or restriction, the Collateral
shall include such property, rights or licenses, and Borrower shall be deemed to
have granted a security interest in all such rights and interests as if such
prohibition or restriction had never been in effect. Notwithstanding termination
of this Agreement, Bank's Lien on the Collateral shall remain in effect for so
long as any Indebtedness is outstanding.

        4.2 Delivery of Additional Documentation Required. Borrower shall from
time to time execute and deliver to Bank, at the request of Bank, all negotiable
Collateral, all financing statements and other documents that Bank may
reasonably request, in form satisfactory to Bank, to perfect and continue
perfected Bank's security interests in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

        4.3 Rights to Inspect. Bank (through any of its officers, employers, or
agents) shall have the right, upon reasonable prior notice, from time to time
during Borrower's usual business hours, to inspect Borrower's Books and to make
copies thereof and to check, test, and appraise the Collateral in order to
verify Borrower's financial condition or the amount, condition of, or any other
matter relating to, the Collateral. Notwithstanding any provision of this
Agreement to the contrary, except upon the occurrence and during the
continuation of an Event of Default, Borrower shall not be required to disclose,
permit the inspection, examination, copying or making extracts of, or discuss,
any document, information or other matter that (i) constitutes non-financial
trade secrets or non-financial proprietary information, or (ii) the disclosure
of which to Bank, or their designated representative, is then prohibited by (a)
law, or (b) an agreement binding on the Borrower that was not entered into by
the Borrower for the primary purpose of concealing information from the Bank.

SECTION 5: CONDITIONS PRECEDENT

and authorized to do business as a corporation in each jurisdiction where the

performance by Borrower of this Agreement, each of the Loan Documents, and any
and all other documents and instruments required under this Agreement and/or to
which it is a party or is otherwise bound are within the corporate powers of

contemplated by this Agreement: Borrower is now and shall be at all times
solvent and able to pay its debts (including trade debts) as they mature.

        6.6 No Material Adverse Change in Financial Statement. All consolidated
financial statements related to Borrower and any Subsidiary that have been
delivered by Borrower to Bank fairly present in all material respects Borrower's
consolidated financial condition as of the date thereof and Borrower's

since the date of the most recent of such financial statements submitted to Bank
on or about the date of this Agreement.

        6.7 Subsidiaries. There are no directly or indirectly owned Subsidiaries

except to the extent such tax payments are being actively and diligently
contested in good faith by appropriate proceedings.

any of its Subsidiaries violated any Environmental Law(s), (ii) asserts or
alleges that Borrower or any of its Subsidiaries is required to clean up,
remove, or take any other remedial or response action due to the disposal,
depositing, discharge, leaking or other release of any hazardous materials, or
(iii) asserts or alleges that Borrower or any of its Subsidiaries is required to
pay all or a portion of any past, present or future clean-up, removal or other
remedial or response action which arises out of or is related to the disposal,
depositing, discharge, leaking or other release of any hazardous materials by
Borrower or any of its Subsidiaries, and which, either singularly or in the
aggregate, could have a Material Adverse Effect upon the business, operations,
conditions (financial or otherwise), performance or properties of Borrower or
any of its Subsidiaries.

<PAGE>   15

                6.13.1 To the best of Borrower's knowledge, there are no
        conditions existing currently which could subject Borrower or any of its
        Subsidiaries to damages, penalties, injunctive relief or clean-up costs
        under any applicable Environmental Law(s), or which require, or are
        likely to require, clean-up, removal, remedial action or other response
        pursuant to any applicable Environmental Law(s) by Borrower or any of
        its Subsidiaries, and which, in any case, either singularly or in
        aggregate, could have a Material Adverse Effect upon the business,
        operations, conditions (financial or otherwise), performance or
        properties of Borrower or any of its Subsidiaries.

                6.13.2 Neither Borrower nor any of its Subsidiaries is subject
        to any judgment, decree, order or citation related to or arising out of
        any applicable Environmental Law(s), which, either singularly or in the
        aggregate, could have a Material Adverse Effect upon the business,
        operations, conditions (financial or otherwise), performance or
        properties of Borrower or any of its Subsidiaries; and, to the best of
        Borrower's knowledge, neither Borrower nor any of its Subsidiaries has
        been named or listed as a potentially responsible party by any
        governmental body or agency in any matter arising under any applicable
        Environmental Law(s).

                6.13.3 Borrower and each of its Subsidiaries have all material
        permits, licenses and approvals required under applicable Environmental
        Laws, where the failure to so obtain or maintain any such permits,
        licenses or approvals could have a Material Adverse Effect upon the
        business, operations, conditions (financial or otherwise), performance
        or properties of Borrower or any of its Subsidiaries.

        6.14 Warranties, Representations and Agreements. Each warranty,
representation and agreement contained in this Agreement shall be automatically
deemed repeated with each Advance and shall be conclusively presumed to have
been relied on by Bank regardless of any investigation made or information
possessed by Bank. The warranties, representations and agreements set forth
herein shall be cumulative and in addition to any and all other warranties,
representations and agreements which Borrower shall give, or cause to be given,
to Bank, either now or hereafter.

        6.15 Merchantable Inventory. All Inventory is in all material respects
of good and marketable quality, free from all material defects.

        6.16 Accuracy of Information. The Financial Statements of Borrower and
its Subsidiaries, previously furnished to Bank, have been prepared in accordance
with GAAP, are complete and correct in all material respects, and fairly present
the financial condition of Borrower and the consolidated financial condition of
Borrower and its Subsidiaries, and the results of their respective operations as
of the dates and for the periods covered thereby; and since the date(s) of said
financial statements, there has been no material adverse change in the financial
condition of Borrower or any of its Subsidiaries. Neither Borrower nor any of
its Subsidiaries has any material contingent obligations, liabilities for taxes,
long-term leases, or long-term commitments not disclosed by, or reserved against
in, such financial statements. Borrower and each of its Subsidiaries is solvent,
able to pay its respective debts as they mature, has capital sufficient to carry
on its business and has assets the fair market value of which exceed its
liabilities, and Borrower will not be rendered insolvent, under-capitalized or
unable to pay debts generally as they become due by the execution or performance
of this Agreement, or any of the other Loan Documents to which it is a party or
by which it is otherwise bound.

SECTION 7: AFFIRMATIVE COVENANTS

        Borrower covenants and agrees that, so long as Bank is committed to make
any Loan(s) under this Agreement, and thereafter, so long as any Indebtedness
remains outstanding under this Agreement, it will, and, as applicable, it will

business substantially as conducted and operated during the present and

franchises and trade names and preserve all the remainder of its property and

election and without demand, do any one or more of the following, all of which
are authorized by Borrower:

                (a) Declare all Indebtedness, whether evidenced by this
        Agreement, by any of the other Loan Documents, or otherwise, immediately
        due and payable (provided that upon the occurrence of an Event of
        Default described in Section 9.1(j), all Indebtedness shall become
        immediately due and payable without any action by Bank);

                (b) Cease advancing money or extending credit to or for the
        benefit of Borrower under this Agreement or under any other agreement
        between Borrower and Bank;

                (c) Terminate this Agreement as to any future liability or
        obligation of Bank, but without affecting Bank's rights and security
        interests in the Collateral, and the Indebtedness of Borrower to Bank;

                (d) Demand that Borrower (i) deposit cash with Bank in an amount
        equal to the amount of any Letters of Credit remaining undrawn, as
        collateral security for the repayment of any future drawings under such
        Letters of Credit, and Borrower shall forthwith deposit and pay such
        amounts, and (ii) pay in advance all Letters of Credit fees scheduled to
        be paid or payable over the remaining term of the Letters of Credit;

                (e) Settle or adjust disputes and claims directly with account

        reasonable to protect its security interest in the Collateral. Borrower

        Collateral available to Bank as Bank may designate. Borrower authorizes
        Bank to enter the premises where the Collateral is located, to take and
        maintain possession of the Collateral, or any part of it, and to pay,
        purchase, contest, or compromise any encumbrance, charge, or lien which
        in Bank's determination appears to be prior or superior to its security
        interest and to pay all expenses incurred in connection therewith. With
        respect to any of Borrower's premises. Borrower hereby grants Bank a
        license to enter such premises and to occupy the same, without charge,
        in order to exercise any of Bank's rights or remedies provided herein,
        at law, in equity, or otherwise;

                (g) Without notice to Borrower set off and apply to the
        Indebtedness any and all (i) balances and deposits of Borrower held by
        Bank, or (ii) indebtedness at any time owing to or for the credit or the
        account of Borrower held by Bank;

                (h) Ship, reclaim, recover, store, finish, maintain, repair,
        prepare for sale, advertise for sale, and sell (in the manner provided
        for herein) the Collateral;


                                       21
<PAGE>   23

                (i) Sell the Collateral at either a public or private sale, or
        both, by way of one or more contracts or transactions, for cash or on
        terms, in such manner and at such places (including Borrower's premises)
        as Bank determines is commercially reasonable, and apply the proceeds
        thereof to the Indebtedness in whatever manner or order Bank deems
        appropriate;

                (j) Bank may credit bid and purchase at any public sale, or at
        any private sale as permitted by law;

                (k) Any deficiency that exists after disposition of the
        Collateral as provided above will be paid immediately by Borrower;

                (l) Without limiting Bank's rights under any security interest,
        Bank is hereby granted a license or other right to use, without charge,
        Borrower's labels, patents, copyrights, rights of use of any name, trade
        secrets, trade names, trademarks and advertising matter, or any property
        of a similar nature as it pertains to the Collateral, in completing
        production of, advertising for sale and selling any Collateral and
        Borrower's rights under all licenses and all franchise agreement shall
        inure to Bank's benefit, and Bank shall have the right and power to
        enter into sublicense agreements with respect to all such rights with
        third parties on terms acceptable to Bank;

                (m) Borrower shall pay all Bank Expenses incurred in connection
        with Bank's enforcement and exercise of any of its rights and remedies
        as herein provided, whether or not suit is commenced by Bank.

        10.2 Power of Attorney. Effective only upon the occurrence and during
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
Account Debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against Account Debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to Account
Debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; (e) settle and adjust disputes and
claims respecting the Accounts directly with Account Debtors, for amounts and
upon terms which Bank determines to be reasonable; (f) to file, in its sole
discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of Borrower
where permitted by law; and (g) to transfer any intellectual property Collateral
into the name of Bank or a third party to the extent permitted under the
California Uniform Commercial Code, provided Bank may exercise such power of
attorney to sign the name of Borrower on any of the documents described in
Section 4.2 regardless of whether an Event of Default has occurred. The
appointment of Bank as Borrower's attorney in fact, and each and every one of
Bank's rights and powers, being coupled with an interest, is irrevocable until
all of the Indebtedness has been fully repaid and performed and Bank's
obligation to provide Advances hereunder is terminated.

        10.3 Accounts Collection. At any time from the date of this Agreement,
Bank may notify any Person owing funds to Borrower of Bank's security interest
in such funds and verify the amount of such Account. Borrower shall collect all
amounts owing to Borrower for Bank, receive in trust all payments as Bank's
trustee, and, if requested or required by Bank, immediately deliver such
payments to Bank in their original form as received from the account debtor,
with proper endorsements for deposit.

        10.4 Bank Expenses. If Borrower fails to pay any amounts or furnish any
required proof of payment due to third persons or entities, as required under
the terms of this Agreement, then Bank may do any or all of the following: (a)
make payment of the same or any part thereof; (b) set up such reserves under the
Committed Revolving Line as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance policies
of the type discussed in Section 7.8 of this Agreement, and take any action with
respect to such policies as Bank deems prudent. Any amounts so paid or deposited
by Bank shall constitute Bank Expenses, shall be immediately due and payable,
and shall bear interest at the then applicable rate hereinabove provided, and
shall be secured by the Collateral. Any payments made by Bank shall not
constitute an agreement by Bank to make similar payments in the future or a

<PAGE>   24

        10.5 Bank's Liability for Collateral. So long as Bank complies with its
obligations under Section 9207 of the Code. Bank shall not in any way or manner
be liable or responsible for: (a) the safekeeping of the Collateral, (b) any
loss or damage thereto occurring or arising in any manner or fashion from any
cause; (c) any diminution in the value thereof; or (d) any act or default of any
carrier, warehouseman, bailee, forwarding agency, or other person whomsoever.
All risk of loss, damage or destruction of the Collateral shall be borne by
Borrower.

        10.6 Waiver of Certain Laws. To the extent permitted by applicable law,
Borrower hereby agrees to waive, and does hereby absolutely and irrevocably
waive and relinquish, the benefit and advantage of any valuation, stay,
appraisement, extension or redemption laws now existing or which may hereafter
exist, which, but for this provision, might be applicable to any sale made under
the judgment, order or decree of any court, on any claim for interest on the
Notes, or any security interest or mortgage contemplated by or granted under or
in connection with this Agreement or the Indebtedness.

        10.7 Waiver of Defaults. No Default or Event of Default shall be waived
by Bank except in a written instrument specifying the scope and terms of such
waiver and signed by an authorized officer of Bank, and such waiver and shall be
effective only for the specific time(s) and purpose(s) given. No single or
partial exercise of any right, power or privilege hereunder, nor any delay in
the exercise thereof, shall preclude other or further exercise of Bank's rights.
No waiver of any Default or Event of Default shall extend to any other or
further Default or Event of Default. No forbearance on the part of Bank in
enforcing any of Bank's rights or remedies hereunder or any of the other Loan
Documents shall constitute a waiver of any of its rights or remedies. Borrower
expressly agrees that this Section may not be waived or modified by Bank by
course of performance, estoppel or otherwise.

        10.8 Receiver. Bank, in any action or suit to foreclose upon any of the
Collateral, shall be entitled, without notice or consent, and completely without
regard to the adequacy of any security for the Indebtedness, to the appointment
of a receiver of the business and premises in question, and of the rents and
profits derived therefrom. This appointment shall be in addition to any other
rights, relief or remedies afforded Bank. Such receiver, in addition to any
other rights to which he shall be entitled, shall be authorized to sell,
foreclose or complete foreclosure on Collateral contemplated by this Agreement
for the benefit of Bank, pursuant to provisions of applicable law.

        10.9 Remedies Cumulative. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not expressly set forth herein as
provided under the UCC, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

        10.10 Demand: Protest. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

SECTION II: MISCELLANEOUS

        11.1 Loans to Borrower. Bank and Borrower agree that any loans which
Bank in its sole discretion has made or may now or hereafter make to Borrower
shall be subject to the terms and conditions of this Agreement unless otherwise
agreed in writing by Bank and Borrower.

        11.2 Accounting Principles. Except to the extent expressly stated to the
contrary herein, where the character or amount of any asset or liability or item
of income or expense is required to be determined, or any consolidation or other
accounting computation is required to be made for purposes of this Agreement, it
shall be done in accordance with GAAP, and all accounting terms not specifically
defined in this Agreement shall be construed in accordance with GAAP.


                                       23
<PAGE>   25

        11.3 Audits of Collateral: Fees. Bank shall have the right from time to
time to audit Borrower's Accounts, Inventory, or other Collateral, provided that
such audits will be conducted upon reasonable notice. Borrower agrees to
reimburse Bank, on demand, for customary and reasonable fees and costs incurred
by Bank for such audits, and for each appraisal of Collateral and financial
analysis and examination of Borrower performed from time to time by its agents.

        11.4 Taxes and Fees. Should any tax (other than a tax based upon the net
income of Bank) or recording or filing fee become payable in respect of this
Agreement or any of the Loan Documents, any of the Collateral, or any amendment,
modification or supplement hereof or thereof, Borrower agrees to pay such taxes
(or reimburse Bank therefor), together with any interest or penalties thereon,
and agree to hold Bank harmless with respect thereto.

        11.5 Governing Law. This Agreement, each of the Notes, and each of the
other Loan and Collateral Documents, shall be deemed to have been delivered in
the State of California, and shall be governed by and construed and enforced in
accordance with the laws of the State of California, except to the extent that
the Uniform Commercial Code, other personal property law or real property law of
another jurisdiction where Collateral is located is applicable, and except to
the extent expressed to the contrary in any of the Loan Documents. Whenever
possible, each provision of this Agreement shall be interpreted in such manner
as to be effective and valid under applicable law, but if any provision of this
Agreement shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Agreement.

        11.6 Costs and Expenses. Borrower shall pay Bank, on demand, all costs
and expenses, including, without limitation, reasonable attorneys' fees and
legal expenses, incurred by Bank in perfecting, revising, protecting or
enforcing any of its rights or remedies against Borrower or any Collateral, or
otherwise incurred by Bank in connection with any Default or Event of Default or
the enforcement of this Agreement, the Loan Documents, or the Indebtedness.
Following Bank's demand upon Borrower for the payment of any such costs and
expenses, and until the same are paid in full, the unpaid amount of such costs
and expenses shall constitute Indebtedness and shall bear interest at the Base
Rate.

        11.7 Notices. All notices and other communications provided for herein
or in any document contemplated hereby, given hereunder or required by law to be
given, shall be in writing (unless expressly provided to the contrary). If
personally delivered, such notices shall be effective when delivered, and in the
case of mailing, such notices shall be effective two (2) Business Days after
sending by first class mail, postage prepaid, in each case addressed to the
parties as set forth on the signature page of this Agreement, or to such other
address as a party shall have designated to the other in writing in accordance
with this Section. The giving of at least five (5) days' notice before Bank
shall take any action described in any notice shall conclusively be deemed
reasonable for all purposes; provided, that this shall not be deemed to require
Bank to give such five (5) days' notice, or any notice, if not specifically
required to do so in this Agreement.

        11.8 Further Action. Borrower, from time to time, upon written request
of Bank, will promptly make, execute, acknowledge and deliver, or cause to be
made, executed, acknowledged and delivered, all such further and additional
instruments, and promptly take all such further action as may be required to
carry out the intent and purpose of this Agreement, and to provide for the Loans
under and payment of the Notes, according to the intent and purpose herein and
therein expressed.

        11.9 Successors and Assigns: Participation. This Agreement shall be
binding upon and shall inure to the benefit of Borrower and Bank and their
respective successors and assigns. The foregoing shall not authorize any
assignment or transfer by Borrower, of any of its respective rights, duties or
obligations hereunder, such assignments or transfers being expressly prohibited.
Bank, however, may freely assign, whether by assignment, participation or
otherwise, its rights and obligations hereunder, and is hereby authorized to
disclose to any such assignee or participant any financial or other information
in its knowledge or possession regarding Borrower, its Subsidiaries and
Affiliates, or the Indebtedness.

        11.10 Indulgence. No delay or failure of Bank in exercising any right,
power or privilege hereunder or under any of the Loan Documents shall affect
such right, power or privilege, nor shall any single or partial exercise thereof
preclude any further exercise thereof, nor the exercise of any other right,
power or privilege available to


                                       24
<PAGE>   26

Bank. The rights and remedies of Bank hereunder are cumulative and are not
exclusive of any rights or remedies of Bank.

        11.11 Amendment and Waiver. No amendment or waiver of any provision of
this Agreement or any Loan Document, nor consent to any departure by Borrower,
therefrom, shall in any event be effective unless the same shall be in writing
and signed by Bank, and then such waiver or consent shall be effective only in
the specific instance(s) and for the specific time(s) and purpose(s) for which
given.

        11.12 Severability. In case any one or more of the obligations of
Borrower under this Agreement, any Note, or any of the other Loan Documents
shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining obligations of Borrower shall not
in any way be affected or impaired thereby, and such invalidity, illegality or
unenforceability in one jurisdiction shall not affect the validity, legality or
enforceability of the obligations of Borrower under this Agreement, the Notes or
any of the other Loan Documents in any other jurisdiction.

        11.13 Headings and Construction of Terms. The headings of the various
sub-Sections hereof are for convenience of reference only and shall in no way
modify or affect any of the terms or provisions hereof. Where the context herein
requires, the singular number shall include the plural, and any gender shall
include any other gender.

        11.14 Independence of Covenants. Each covenant hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any such covenant, the fact that it would be permitted by an exception to, or
would be otherwise within the limitations of, another covenant shall not avoid
the occurrence of any Default or Event of Default.

        11.15 Reliance on and Survival of Various Provisions. All terms,
covenants, agreements, representations and warranties of Borrower made herein or
in any of the Loan Documents, or in any certificate, report, financial statement
or other document furnished by or on behalf of Borrower in connection with this
Agreement or any of the Loan Documents, shall be deemed to have been relied upon
by Bank, notwithstanding any investigation heretofore or hereafter made by Bank
or on Bank's behalf, and those covenants and agreements of Borrower set forth in
this Agreement (together with any other indemnities of Borrower contained
elsewhere in this Agreement or in any of the Loan Documents) shall survive the
termination of this Agreement and the repayment in full of the Indebtedness.

        11.16 Effective Upon Execution. This Agreement shall become effective
upon the execution hereof by Bank and Borrower, and shall remain effective until
the Indebtedness under this Agreement and each of the Notes shall have been
repaid and discharged in full and no commitment to extend any credit hereunder
(whether optional or obligatory) remains outstanding.

        11.17 Complete Agreement: Conflicts. This Agreement, the Notes, the
other Loan Documents, any agreements, certificates, or other documents given in
connection with the Indebtedness under this Agreement, and any commitment letter
previously issued by Bank with respect thereto (provided that in the event of
any inconsistency or conflict between this Agreement and the other Loan
Documents, on one hand, and such commitment letter, on the other hand, this
Agreement and the Loan Documents shall control), contain the entire agreement of
the parties thereto and supersedes all prior agreements and understandings
related to the subject matter hereof, and none of the parties shall be bound by
anything not expressed in writing. In the event that and to the extent that any
of the terms, conditions or provisions of any of the other Loan Documents are
inconsistent with or in conflict with any of the terms, conditions or provisions
of this Agreement, the applicable terms, conditions and provisions of this
Agreement shall govern and control.

        11.18 Confidentiality. In handling any confidential information, Bank
shall exercise the same degree of care that it exercises with respect to its own
proprietary information of the same types to maintain the confidentiality of any
non-public information thereby received or received pursuant to this Agreement,
except that disclosure of such information may be made (a) to the subsidiaries
or affiliates of Bank in connection with their present or prospective business
relations with Borrower; (b) to prospective transferees or purchasers of any
interest in the Loans, provided that they have entered into a comparable
confidentiality agreement in favor of Borrower and have delivered a copy to
Borrower; (c) as required by law, regulations, rule or order, subpoena, judicial
order or similar


                                       25
<PAGE>   27

order; (d) as may be required in connection with the examination, audit or
similar investigation of Bank, and, (e) as Bank may deem appropriate in
connection with the exercise of any remedies hereunder. Confidential information
hereunder shall not include information that either: (i) is in the public domain
or in the knowledge or possession of Bank when disclosed to Bank, or becomes
part of the public domain after disclosure to Bank through no fault of Bank; or,
(ii) is disclosed to Bank by a third party, provided Bank does not have actual
knowledge that such third party is prohibited from disclosing such information.

        11.19 WAIVER OF JURY TRIAL. BANK AND BORROWER EACH ACKNOWLEDGE THAT THE
RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH
OF THEM, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT, WITH COUNSEL
OF THEIR CHOICE, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT ANY
OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT
OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR LOAN DOCUMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING,
STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTION OF ANY OF THEM. THESE PROVISIONS
SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY BANK
OR BORROWER, EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM.

        11.20 Counterparts. This Agreement may be executed in any number of
counterparts and by different parties on separate counterparts, each of which,
when executed and delivered, shall be deemed to be an original, and all of
which, when taken together, shall constitute but one and the same Agreement.

        WITNESS the due execution hereof as of the day and year first above
written.

                 SENIOR LOAN AND SECURITY AGREEMENT NO. 053-6193

THIS SENIOR LOAN AND SECURITY AGREEMENT NO. 053-6193 (this "Security Agreement")
is dated as of November 5, 1998 between AVANEX CORPORATION, a California
corporation ("Borrower") and PHOENIX LEASING INCORPORATED, a California
corporation ("Lender").

                                    RECITALS

      A. Borrower desires to borrow from Lender in one or more borrowings an
amount not to exceed $1,300,000 in the aggregate, and Lender desires to loan,
subject to the terms and conditions herein set forth, such amount to Borrower
(each, a "Loan" and collectively, the "Loans"). Such borrowings shall be
evidenced by one or more Senior Secured Promissory Notes (each, a "Note" and
collectively, the "Notes"), in the form attached hereto.

      B. As security for Borrower's obligations to Lender under this Security
Agreement, the Notes and any other agreement between Borrower and Lender,
Borrower will grant to Lender hereunder a first priority security interest in
certain of its equipment, machinery, fixtures, other items and intangibles and
also certain custom use equipment, installation and delivery costs, purchase
tax, toolings, software and other items generally considered fungible or
expendable ("Soft Costs") whether now owned by Borrower or hereafter acquired,
and all substitutions and replacements of and additions, improvements,
accessions and accumulations to said equipment, machinery and fixtures and other
items, together with all rents, issues, income, profits and proceeds therefrom
(collectively, the "Collateral") which is described on the Note attached hereto
or any subsequently-executed Note entered into by Lender and Borrower and which
incorporates this Security Agreement by reference.

NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS:

SECTION 1. TERM OF AGREEMENT. The term of this Security Agreement begins on the
date set forth above and shall continue thereafter and be in effect so long as
and at any time any Note entered into pursuant to this Security Agreement is in
effect. The Term and monthly payment amount payable with respect to each item of
Collateral shall be as set forth in and as stated in the respective Note(s). The
terms of each Note hereto are subject to all conditions and provisions of this
Security Agreement as it may at any time be amended. Each Note shall constitute
a separate and independent Loan and contractual obligation of Borrower and shall
incorporate the terms and conditions of this Security Agreement and any
additional provisions contained in such Note. In the event of a conflict between
the terms and conditions of this Security Agreement and any provisions of such
Note, the provisions of such Note shall prevail with respect to such Note only.

SECTION 2. NON-CANCELABLE LOAN. This Security Agreement and each Note cannot be
canceled or terminated except as expressly provided herein. Borrower agrees that
its obligations to pay all monthly payment amounts and other sums payable
hereunder (and under any Note) and the rights of Lender and any assignee in and
to such rent and other sums, are absolute and unconditional and are not subject
to any abatement, reduction, setoff, defense, counterclaim or recoupment due or
alleged to be due to, or by reason of, any past, present or future claims which
Borrower may have against Lender, any assignee, the manufacturer or seller of
the Collateral, or against any person for any reason whatsoever.

SECTION 3. LENDER COMMITMENT. (a) General Terms. Subject to the terms and
conditions of

<PAGE>   2
this Security Agreement and so long as no Event of Default or event which with
the giving of notice or passage of time, or both, would become an Event of
Default has occurred and is continuing, Lender hereby agrees to make one or more
senior secured Loans to Borrower, subject to the following conditions: (i) each
Loan shall be evidenced by a Note; (ii) the total principal amount of the Loans
shall not exceed $1,300,000 in the aggregate (the "Commitment"); (iii) at the
time of each Loan, no Event of Default or event which with the giving of notice
or passage of time, or both, would become an Event of Default shall have
occurred and be continuing, as reasonably determined by Lender, and certified by
Borrower; (iv) the amount of each Loan shall be at least $25,000 except for a
final Loan which may be less than $25,000; (v) Lender shall not be obligated to

extended to August 31, 1999 if Lender has received and approved in its sole
discretion Borrower's monthly 2000 business plan; (vi) for each Loan, Borrower
shall present to Lender a list of proposed Collateral for approval by Lender in
its sole discretion; (vii) for each Loan, Borrower shall have provided Lender

Sheet," 2 pages, dated September 16, 1998 (the "Business Plan"), as may be
amended from time to time in form and substance acceptable to Lender; (ix) there
shall be no material adverse change in Borrower's condition, financial or
otherwise, that would materially impair the ability of Borrower to meet its

reasonably determined by Lender, and Borrower so certifies, from (yy) the date

the date of the proposed Loan; (x) Borrower shall use the proceeds of all Loans

address as Lender specifies in writing, all amounts payable to it under this
Security Agreement and the Notes.

SECTION 7. LOCATION; INSPECTION; LABELS. Except for "mobile goods" (as such term

limitation, laptop computers and other mobile equipment, and other equipment
used at trade shows, all of the Collateral shall be located at the address (the
"Collateral Location") shown on Exhibit A to each Note and shall not be moved
without Lender's prior written consent which location shall in all events be
within the United States. All of the



                                       3
<PAGE>   4
records regarding the Collateral shall be located at 42501 Albrae Street,
Fremont, CA 94538, or such other location of which Borrower has given notice to
Lender in accordance with this Security Agreement. Lender shall have the right
to inspect Collateral, including records relating thereto, and Borrower's books
and records at any time (upon reasonable notification) during regular business
hours, such books and records to be maintained in accordance with generally
accepted accounting principles. Borrower shall be responsible for all labor,
material and freight charges incurred in connection with any removal or
relocation of Collateral which is requested by Borrower and consented to by
Lender, as well as for any charges due to the installation or moving of the
Collateral. Payments under the Notes and under this Security Agreement shall
continue during any period in which the Collateral is in transit during a
relocation. During Borrower's regular business hours and upon at least two days'
notice to Borrower, Lender or its agent shall mark and label Collateral, which
labels (to be provided by Lender) shall state that such Collateral is subject to
a security interest of Lender, and Borrower shall keep such labels on the
Collateral as so labeled.

SECTION 8. COLLATERAL MAINTENANCE. (a) General. Upon reasonable notice, Borrower
will reasonably permit Lender to inspect each item of Collateral and its
maintenance records during Borrower's regular business hours. Borrower will at
its sole expense comply with all applicable laws, rules, regulations,
requirements and orders with respect to the use, maintenance, repair, condition,
storage and operation of each item of Collateral. Any addition or improvement
that is so required or cannot be so removed will immediately become Collateral
of Lender. (b) Service and Repair. Borrower will at its sole expense maintain
and service and repair any damage to each item of Collateral in a manner
consistent with prudent industry practice and Borrower's own practice so that
such item of Collateral is at all times (i) in the same condition as when
delivered to Borrower, except for ordinary wear and tear, and (ii) in good
operating order for the function intended by its manufacturer's warranties and
recommendations.

SECTION 9. LOSS OR DAMAGE. Borrower assumes the entire risk of loss to the
Collateral through use, operation or otherwise. Borrower hereby indemnifies and
holds harmless Lender from and against all claims, loss of Loan payments, costs,
damages, and expenses relating to or resulting from any loss, damage or
destruction of the Collateral, any such occurrence being hereinafter called a
"Casualty Occurrence." No later than sixty (60) days after such Casualty
Occurrence, Borrower shall, at its election, either: (a) repair the Collateral
returning it to good operating condition, or (b) replace the Collateral with
Collateral acceptable to Lender in its reasonable discretion, in good condition
and repair taking all steps required by Lender to perfect Lender's first
priority security interest therein, which replacement Collateral shall be
subject to the terms of this Security Agreement, or (c) pay to Lender an amount
equal to the Balance Due (as defined below) for each lost or damaged item of
Collateral. The Balance Due for each such item is the sum of: (i) all amounts
for each item which may be then due or accrued to the payment date, plus (ii) as
of such payment date, an amount discounted to present value at 6% equal to the
product of the fraction specified below times the sum of all remaining payments
under the respective Note, including the amount of any mandatory or optional
payment required or permitted to be paid by Borrower to Lender at the maturity
of the Note. The numerator of the fraction shall be the collateral value (as set
forth on the applicable Note) of the item and the denominator shall be the
aggregate collateral value of all items under the Note. Upon the making of such
payments, Lender shall release such item of Collateral from its lien hereunder.

SECTION 10. INSURANCE. Borrower at its expense shall keep the Collateral insured
against all risks of physical loss for at least the replacement value of the
Collateral (including, in the case of Collateral which is vehicles,
comprehensive and collision coverage) and in no event for less than the amount
payable following a Casualty Occurrence (as provided in Section 9). Such
insurance shall provide for a loss payable endorsement to Lender and/or any
assignee of Lender. Borrower shall maintain commercial general liability
insurance, including products liability and completed operations coverage, with
respect to loss or damage



                                       4
<PAGE>   5
for personal injury, death or property damage in an amount not less than
$2,000,000 in the aggregate, (and in the case of Collateral which is vehicles,
in an amount not less than $1,000,000 covering bodily injury and property damage
in a combined single limit) naming Lender and/or Lender's assignee as additional
insured. Such insurance shall contain insurer's agreement to give thirty (30)
days' advance written notice to Lender before cancellation or material change of
any policy of insurance. Borrower will provide Lender and any assignee of Lender
with a certificate of insurance from the insurer evidencing Lender's or such
assignee's interest in the policy of insurance. Such insurance shall cover any
Casualty Occurrence to any unit of Collateral. Notwithstanding anything in
Section 9 or this Section 10 to the contrary, this Security Agreement and
Borrower's obligations hereunder shall remain in full force and effect with
respect to any unit of Collateral which is not subject to a Casualty Occurrence.
If Borrower fails to provide or maintain insurance as required herein, Lender
shall have the right, but shall not be obligated, to obtain such insurance. In
that event, Borrower shall pay to Lender the cost thereof.

SECTION 11. MISCELLANEOUS AFFIRMATIVE COVENANTS. So long as any portion of the
Indebtedness is unpaid and as long as any of the Obligations are outstanding
Borrower will: (a) duly pay all governmental taxes and assessments at the time
they become due and payable; provided, however, Borrower may contest the same in
good faith so long as no payment default by Borrower has occurred and is
continuing; (b) comply with all applicable material governmental laws, rules and
regulations relating to its business and the Collateral where a failure to
comply could reasonably be expected to have a Material Adverse Effect; (c) take
no action to adversely affect Lender's security interest in the Collateral as a
first and prior perfected security interest; (d) furnish Lender with its annual
audited financial statements within one hundred twenty (120) days following the
end of Borrower's fiscal year, unaudited quarterly financial statements within
forty-five (45) days after the end of each fiscal quarter, and within thirty
(30) days of the end of each month a financial statement for that month prepared
by Borrower, and including an income statement and balance sheet, all of which
shall be certified by an officer of Borrower as true and correct and shall be
prepared in accordance with generally accepted accounting principles
consistently applied, and such other information as Lender may reasonably
request; and (e) promptly (but in no event more than five (5) days after the
occurrence of such event) notify Lender of any change in Borrower's condition
during the commitment period which constitutes a Material Adverse Effect, and of
the occurrence of any Event of Default.

SECTION 12. INDEMNITIES. Borrower will protect, indemnify and save harmless
Lender and any assignees from and against all liabilities, obligations, claims,
damages, penalties, causes of action, costs and expenses (including reasonable
attorneys' fees and expenses), imposed upon or incurred by or asserted against
Lender or any assignee of Lender by Borrower or any third party by reason of the
occurrence or existence (or alleged occurrence or existence) of any act or event
relating to or caused by any portion of the Collateral, or its purchase,
acceptance, possession, use, maintenance or transportation, including without
limitation, consequential or special damages of any kind, any failure on the
part of Borrower to perform or comply with any of the terms of this Security
Agreement or any Note, claims for latent or other defects, claims for patent,
trademark or copyright infringement and claims for personal injury, death or
property damage, including those based on Lender's negligence or strict
liability in tort and excluding only those based on Lender's gross negligence or
willful misconduct. In the event that any action, suit or proceeding is brought
against Lender by reason of any such occurrence, Borrower, upon Lender's
request, will, at Borrower's expense, resist and defend such action, suit or
proceeding or cause the same to be resisted and defended by counsel designated
and approved by Lender. Borrower's obligations under this Section 12 shall
survive the payment in full of all the Indebtedness and the performance of all
Obligations with respect to acts or events occurring or alleged to have occurred
prior to the payment in full of all the Indebtedness and the performance of all
Obligations.



                                       5
<PAGE>   6
SECTION 13. TAXES. Borrower agrees to reimburse Lender (or pay directly if
instructed by Lender) and any assignee of Lender for, and to indemnify and hold
Lender and any assignee harmless from, all fees (including, but not limited to,
license, documentation, recording and registration fees), and all sales, use,
gross receipts, personal property, occupational, value added or other taxes,
levies, imposts, duties, assessments, charges, or withholdings of any nature
whatsoever, together with any penalties, fines, additions to tax, or interest
thereon (the foregoing collectively "Impositions"), except same as may be
attributable to Lender's income, arising at any time prior to or during the term
of any Notes or of this Security Agreement, or upon termination or early
termination of this Security Agreement and levied or imposed upon Lender
directly or otherwise by any Federal, state or local government in the United
States or by any foreign country or foreign or international taxing authority
upon or with respect to (a) the Collateral, (b) the exportation, importation,
registration, purchase, ownership, delivery, leasing, financing, possession,
use, operation, storage, maintenance, repair, return, sale, transfer of title,
or other disposition thereof, (c) the rentals, receipts, or earnings arising
from the Collateral, or any disposition of the rights to such rentals, receipts,
or earnings, (d) any payment pursuant to this Security Agreement or the Notes,
or (e) this Security Agreement, the Notes or any transaction or any part hereof
or thereof.

SECTION 14. RELEASE OF LIENS. Upon payment of all of the Indebtedness and
performance of all of the Obligations, Lender shall execute UCC termination
statements and such other documents as Borrower shall reasonably request to
evidence the release of Lender's lien relating to the Collateral.

SECTION 15. ASSIGNMENT. WITHOUT LENDER'S PRIOR WRITTEN CONSENT WHICH CONSENT
WILL NOT BE UNREASONABLY WITHHELD OR DELAYED, BORROWER SHALL NOT (a) ASSIGN,
TRANSFER, PLEDGE, HYPOTHECATE OR OTHERWISE DISPOSE OF THIS SECURITY AGREEMENT,
ANY NOTE, ANY COLLATERAL, OR ANY INTEREST THEREIN, (b) LEASE OR LEND COLLATERAL
OR PERMIT IT TO BE USED BY ANYONE OTHER THAN BORROWER OR BORROWER'S EMPLOYEES,
CONTRACTORS AND AGENTS OR (c) MERGE INTO, CONSOLIDATE WITH OR CONVEY OR TRANSFER
ITS PROPERTIES SUBSTANTIALLY AS AN ENTIRETY TO ANY OTHER PERSON OR ENTITY.
LENDER MAY ASSIGN ANY OF THE NOTES, THIS SECURITY AGREEMENT OR ITS SECURITY
INTEREST IN ANY OR ALL COLLATERAL, OR ANY OR ALL OF THE ABOVE, IN WHOLE OR IN
PART TO ONE OR MORE ASSIGNEES OR SECURED PARTIES WITHOUT NOTICE TO BORROWER. If
Borrower is given notice of such assignment it agrees to acknowledge receipt
thereof in writing and Borrower shall execute such additional documentation as
Lender's assignee and/or secured party shall reasonably require at Lender's
expense. Each such assignee and/or secured party shall have all of the rights,
but (except as provided in this Section 15) none of the obligations, of Lender
under this Security Agreement, unless such assignee or secured party expressly
agrees to assume such obligations in writing, provided that notwithstanding
anything contained herein, any assignee of any portion of Lender's commitment
and obligation to extend Loans as set forth in Section 3(a)(ii) of this Security
Agreement, shall be obligated to extend such Loans. Borrower shall not assert
against any assignee and/or secured party any defense, counterclaim or offset
that Borrower may have against Lender. Notwithstanding any such assignment, and
providing no Event of Default has occurred and is continuing, Lender, or its
assignees, secured parties, or their agents or assigns, shall not interfere with
Borrower's right to quietly enjoy use of Collateral subject to the terms and
conditions of this Security Agreement. Subject to the foregoing, the Notes and
this Security Agreement shall inure to the benefit of, and are binding upon, the
successors and assignees of the parties hereto. Borrower acknowledges that any
such assignment by Lender will not change Borrower's duties or obligations under
this Security Agreement and the Notes or increase any burden or risk on
Borrower.



                                       6
<PAGE>   7
SECTION 16. DEFAULT. (a) Events of Default. Any of the following events or
conditions shall constitute an "Event of Default" hereunder: (i) Borrower's
failure to pay any monies due to Lender hereunder or under any Note beyond the
tenth (10th) day after the same is due; (ii) Borrower's failure to comply with
its obligations under Section 10 or Section 15; (iii) any representation or
warranty of Borrower made in this Security Agreement or the Notes or in any
other agreement, statement or certificate furnished to Lender in connection with
this Security Agreement or the Notes shall prove to have been incorrect in any
material respect when made or given; (iv) Borrower's failure to comply with or
perform any material term, covenant or condition of this Security Agreement or
any Note or under any other agreement between Borrower and Lender or under any
lease or mortgage of real property covering the location of the Collateral if
such failure to comply or perform is not cured by Borrower within thirty (30)
days after Borrower knows of the noncompliance or nonperformance or notice from
Lender or such longer period that Borrower is diligently attempting to effect
such cure; (v) seizure of any of the Collateral under legal process; (vi) the
filing by or against Borrower or any guarantor under any guaranty executed in
connection with this Security Agreement ("Guarantor") of a petition for
reorganization or liquidation under the Bankruptcy Code or any amendment thereto
or under any other insolvency law providing for the relief of debtors provided
that in the case of all such involuntary proceedings, same are not dismissed
within sixty (60) days after commencement; (vii) the voluntary or involuntary
making of an assignment of a substantial portion of its assets by Borrower or by
any Guarantor for the benefit of its creditors, the appointment of a receiver or
trustee for Borrower or any Guarantor or for any of Borrower's or Guarantor's
assets, the institution by or against Borrower or any Guarantor of any formal or
informal proceeding for dissolution, liquidation, settlement of claims against
or winding up of the affairs of Borrower or any Guarantor provided that in the
case of all such involuntary proceedings, same are not dismissed within sixty
(60) days after commencement; (viii) the making by Borrower or by any Guarantor
of a transfer of all or a material portion of Borrower's or Guarantor's assets
or inventory not in the ordinary course of business; or (ix) any default or
breach by any Guarantor of any of the terms of its guaranty to Lender in
connection with this Security Agreement.

      (b) Remedies. If any Event of Default has occurred and is continuing,
Lender may in its sole discretion exercise one or more of the following remedies
with respect to any or all of the Collateral: (i) declare due any or all of the
aggregate sum of all remaining payments under the Notes, including the amount of
any mandatory or optional payment required or permitted to be paid by Borrower
to Lender at the maturity of the Notes ("Remaining Payments"); (ii) proceed by
appropriate court action or actions either at law or in equity to enforce
Borrower's performance of the applicable covenants of the Notes and this
Security Agreement or to recover all damages and expenses incurred by Lender by
reason of an Event of Default; (iii) except as provided by law, without court
order or prior demand, enter upon the premises where the Collateral is located
and take immediate possession of and remove it without liability of Lender to
Borrower or any other person or entity; (iv) terminate this Security Agreement
and sell the Collateral at public or private sale, or otherwise dispose of,
hold, use or lease any or all of the Collateral in a commercially reasonable
manner; or (v) exercise any other right or remedy available to it under
applicable law. If Lender has declared due any or all of the Remaining Payments,
Borrower will pay immediately to Lender, without duplication, (A) the Remaining
Payments discounted at 6% per annum compounded monthly on the basis of a 360 day
year, (B) all amounts which may be then due or accrued, and (C) all other
amounts due under this Security Agreement and under the Notes (Lender's Return,
as referred to below, means the amounts described in clauses (A), (B) and (C)
above). The net proceeds of any sale or lease of such Collateral will be
credited against Lender's Return. The net proceeds of a sale of the Collateral
pursuant to this Section 16(b) is defined as the sales price of the Collateral
less selling expenses, including, without limitation, costs of remarketing the
Collateral and all refurbishing costs and commissions paid with respect to such
remarketing.



                                       7
<PAGE>   8
Borrower agrees to pay all reasonable out-of-pocket costs of Lender incurred in
enforcement of this Security Agreement, the Notes or any instrument or agreement
required under this Security Agreement, including, but not limited to reasonable
attorneys' fees and litigation expenses and fees of collection agencies ("Remedy
Expenses"). At Lender's request, Borrower shall assemble the Collateral and make
it available to Lender at such time and location as Lender may reasonably
designate. Borrower waives any right it may have to redeem the Collateral.

Declaration that any or all amounts under this Security Agreement and/or the
Notes are immediately due and payable and Lender's taking possession of any or
all Equipment shall not terminate this Security Agreement or any of the Notes
unless Lender so notifies Borrower in writing. None of the above remedies is
intended to be exclusive but each is cumulative and may be enforced separately
or concurrently.

      (c) Application of Proceeds. The proceeds of any sale of all or any part
of the Collateral and the proceeds of any remedy afforded to Lender by this
Security Agreement shall be paid to and applied as follows:

            First, to the payment of reasonable costs and expenses of suit or
foreclosure, if any, and of the sale, if any, including, without limitation,
refurbishing costs, costs of remarketing and commissions related to remarketing,
all Remedy Expenses, all expenses, liabilities and advances incurred or made
pursuant to this Security Agreement or any Note by Lender in connection with
foreclosure, suit, sale or enforcement of this Security Agreement or the Notes,
and taxes, assessments or liens superior to Lender's security interest granted
by this Security Agreement;

            Second, to the payment of all other amounts not described in item
Third below due under this Security Agreement and all Notes;

            Third, to pay Lender an amount equal to Lender's Return, to the
extent not previously paid by Borrower; and

            Fourth, to the payment of any surplus to Borrower or to whomever may
lawfully be entitled to receive it.

      (d) Effect of Delay: Waiver: Foreclosure on Collateral. No delay or
omission of Lender, in exercising any right or power arising from any Event of
Default shall prevent Lender from exercising that right or power if the Event of
Default continues. No waiver of an Event of Default, whether full or partial, by
Lender or such holder shall be taken to extend to any subsequent Event of
Default, or to impair the rights of Lender in respect of any damages suffered as
a result of the Event of Default. The giving, taking or enforcement of any other
or additional security, collateral or guaranty for the payment or discharge of
the Indebtedness and performance of the Obligations shall in no way operate to
prejudice, waive or affect the security interest created by this Security
Agreement or any rights, powers or remedies exercised hereunder or thereunder.
Lender shall not be required first to foreclose on the Collateral prior to
bringing an action against Borrower for sums owed to Lender under this Security
Agreement or under any Note.

SECTION 17. LATE PAYMENTS. Borrower shall pay Lender a late charge of 8% of any
payment owed Lender by Borrower which is not paid when due (taking into account
applicable grace periods), for each month such payment is not paid when due, but
in no event an amount greater than the highest rate permitted by applicable law.
If such amounts have not been received by Lender at Lender's place of business
or by



                                       8
<PAGE>   9
Lender's designated agent by the date such amounts are due under this Security
Agreement or the Notes, Lender shall bill Borrower for such charges. Borrower
acknowledges that invoices for amounts due hereunder or under the Notes are sent
by Lender for Borrower's convenience only. Borrower's non-receipt of an invoice
will not relieve Borrower of its obligation to make payments hereunder or under
the Notes.

SECTION 18. PAYMENTS BY LENDER. If Borrower shall fail to make any payment or
perform any act required hereunder (including, but not limited to, maintenance
of any insurance required by Section 10), then Lender may, but shall not be
required to, after such notice to Borrower as is reasonable under the
circumstances, make such payment or perform such act with the same effect as if
made or performed by Borrower. Borrower will upon demand reimburse Lender for
all sums paid and all reasonable costs and expenses incurred in connection with
the performance of any such act.

SECTION 19. FINANCING STATEMENTS. Borrower hereby appoints Lender (and each of
Lender's officers, employees or agents designated by Lender) with full power of
substitution by Lender, as Borrower's attorney, with power to execute and
deliver on Borrower's behalf, financing statements and other documents necessary
to perfect and/or give notice of Lender's security interest in any of the
Collateral. Notwithstanding the above, Borrower will, upon Lender's request,
execute all financing statements pursuant to the Uniform Commercial Code and all
such other documents reasonably requested by Lender to perfect Lender's security
interests hereunder. Borrower authorizes Lender to file financing statements
signed only by Lender (where such authorization is permitted by law) at all
places where Lender deems necessary.

SECTION 20. NATURE OF TRANSACTION. Lender makes no representation whatsoever,
express or implied, concerning the legal character of the transaction evidenced
hereby, for tax or any other purpose.

SECTION 21. SUSPENSION OF LENDER'S OBLIGATIONS. The obligations of Lender
hereunder will be suspended to the extent that Lender is hindered or prevented
from complying therewith because of labor disturbances, including but not
limited to strikes and lockouts, acts of God, fires, floods, storms, accidents,
industrial unrest, acts of war, insurrection, riot or civil disorder, any order,
decree, law or governmental regulations or interference, failure of the
manufacturer to deliver any item of Collateral or any cause whatsoever not
within the sole and exclusive control of Lender.

SECTION 22. LENDER'S EXPENSE. Borrower shall pay Lender all reasonable costs and
expenses including reasonable attorney's fees and the fees of collection
agencies, incurred by Lender (a) in enforcing any of the terms, conditions or
provisions hereof and related to the exercise of its remedies, and (b) in
connection with any bankruptcy or post-judgment proceeding, whether or not suit
is filed and, in each and every action, suit or proceeding, including any and
all appeals and petitions therefrom.

SECTION 23. ALTERATIONS; ATTACHMENTS. Other than in conformity with the
manufacturer's warranty and/or other functional improvements, no alterations or
attachments shall be made to the Collateral without Lender's prior written
consent, which shall not be given for changes that will affect the reliability
and utility of the Collateral or which cannot be removed without damage to the
Collateral, or which in any way affect the value of the Collateral for purposes
of resale or lease. All attachments and improvements to the Collateral shall be
deemed to be "Collateral" for purposes of the Security Agreement, and a first
priority security interest therein shall immediately vest in Lessor.

SECTION 24. COMMITMENT FEE. Borrower has paid to Lender a commitment fee ("Fee")
of $13,000. The Fee shall be applied by Lender to reimburse Lender for all
out-of-pocket UCC and other search costs, inspections and labeling costs and
appraisal fees, if any, incurred by Lender. The balance shall then be



                                       9
<PAGE>   10
applied proportionally to the first monthly payment for each Note hereunder in
the proportion that the Collateral value for such Note bears to Lender's entire
commitment. However, the portion of the Fee which is not applied to such monthly
payments shall be non-refundable except if Lender defaults in its obligation to
fund Loans pursuant to Section 3.

SECTION 25. NOTICES. All notices hereunder shall be in writing, by registered
mail, or reliable messenger or delivery service (including overnight service)
and shall be directed, as the case may be, to Lender at 2401 Kerner Boulevard,
San Rafael, California 94901, Attention: Asset Management and to Borrower at
42501 Albrae Street, Fremont, CA 94538, Attention: Jessy Chao.

SECTION 26. MISCELLANEOUS. (a) Borrower shall provide Lender with such corporate
resolutions, financial statements and other documents as Lender shall reasonably
request from time to time. (b) Borrower represents that the Collateral hereunder
is used solely for business purposes. (c) Time is of the essence with respect to
this Security Agreement. (d) Borrower acknowledges that Borrower has read this
Security Agreement and the Notes, understands them and agrees to be bound by
their terms and further agrees that this Security Agreement and the Notes
constitute the entire agreement between Lender and Borrower with respect to the
subject matter hereof and supersede all previous agreements, promises, or
representations. (e) This Security Agreement and the Notes may not be changed,
altered or modified except by an instrument signed by an officer or authorized
representative of Lender and Borrower. (f) Any failure of Lender to require
strict performance by Borrower or any waiver by Lender of any provision herein
or in a Note shall not be construed as a consent or waiver of any other breach
of the same or any other provision. (g) If any provision of this Security
Agreement or any Note is held invalid, such invalidity shall not affect any
other provisions hereof or thereof. (h) The obligations of Borrower to pay the
Indebtedness and perform the Obligations shall survive the expiration or earlier
termination of this Security Agreement and each Note until all Obligations of
Borrower to Lender have been met and all liabilities of Borrower to Lender and
any assignee have been paid in full. (i) Borrower will notify Lender at least 30
days before changing its name, principal place of business or chief executive
office. (j) Borrower will, at its expense, promptly execute and deliver to
Lender such documents and assurances (including financing statements) and take
such further action as Lender may reasonably request in order to carry out the
intent of this Security Agreement and Lender's rights and remedies.

SECTION 27. JURISDICTION AND WAIVER OF JURY TRIAL. This Security Agreement and
the Notes shall be deemed to have been negotiated, entered into and performed in
the State of California and it is understood and agreed that the validity of
this Security Agreement and of any of the terms and provisions, of the Security
Agreement and Notes, as well as the rights and duties of Lender and Borrower,
shall be construed pursuant to and in accordance with the laws of the State of
California, without giving effect to conflicts of law principles. It is agreed
that exclusive jurisdiction and venue for any legal action between the parties
arising out of or relating to this Security Agreement and each Note shall be in
the Superior Court for Marin County, California, or, in cases where federal
diversity jurisdiction is available, in the United States District Court for the
Northern District of California situated in San Francisco. BORROWER, TO THE
EXTENT IT MAY LAWFULLY DO SO, HEREBY WAIVES ITS RIGHT TO TRIAL BY JURY IN ANY
ACTION BROUGHT ON OR WITH RESPECT TO THIS SECURITY AGREEMENT, ANY NOTE, ANY
SECURITY DOCUMENTS, OR ANY OTHER AGREEMENTS EXECUTED IN CONNECTION HEREWITH.

SECTION 28. ADDITIONAL INTEREST COMPENSATION: (a) General. Borrower shall be
required to choose a final payment or Note extension election ("Additional
Interest Compensation") at the expiration of the first Note's term. Borrower
shall provide written notice of its election to Lender at least 90 days prior



                                       10
<PAGE>   11
to the end of the term of the first Note. That choice shall be an election of
Borrower's additional interest compensation election for all, but not less than
all, of the Collateral under all Notes under the Security Agreement.

Fair market value shall be determined for the Collateral under all Notes prior
to the first Note's expiration.

In the event Borrower does not provide 90 days' prior written notice of its
election, the Loan shall continue on at the original Loan rate until such 90
days' notice is given and then for an additional 90 days following such notice.
At the end of such notice period, payments under Borrower's election shall be
due.

(b) End of Loan Position Elections. As Additional Interest Compensation,
Borrower shall be required to:

Election No. 1: Make a final payment equal to the Collateral's fair market
value, in no event less than 10% nor more than 20% of the Note's original
principal amount. Fair market value shall be determined by Lender.

Election No. 2: Extend the Note's term for an additional 12 months ("Extended
Term") for a monthly rate of 1.85% of the Note's original principal amount.

IN WITNESS WHEREOF, Borrower and Lender have caused this Security Agreement to
be executed as of the date and year first above written.

MASTER LEASE No. S7280, dated June 2, 1999

FINOVA Capital Corporation ("we", "us" or "FINOVA") agrees to lease to Avanex
Corporation ("you" or "Lessee") and you agree to lease from us, the Equipment
described in any schedule to this Lease (a "Schedule"). The Equipment also
includes any replacement parts, repairs, additions and accessories that you may
add to the Equipment. We may treat any Schedule as a separate lease containing
all of the provisions of this Lease.

      1.    PURCHASING AND INSTALLING THE EQUIPMENT

      We will purchase the Equipment from the Supplier you chose. The Supplier
      will deliver the Equipment to you at your expense. You will properly
      install the Equipment at your expense at the location(s) indicated in the
      Schedule.

      2.    TERM

      -     The Term of each Schedule begins when any of the Equipment on that
            Schedule is delivered to you, or a later date that we agree to in
            writing.

      -     The Term continues until you fully perform in all material respects
            all of your obligations under this Lease and the Schedule.

      -     If the Equipment is not delivered, installed and accepted by you by
            the date indicated in the Schedule, we may terminate this Lease and
            the Schedule as to the Equipment that was not delivered, installed
            and accepted by giving you 10 days written notice of termination.

      -     Before we make any progress payment or final payment for the
            Equipment on any Schedule, we require the following:

      -     That no payment is past due to us under any lease, loan or other
            financial arrangement that you or any guarantor have with us.

      -     That you are complying in all material respects with all the terms
            of this Lease.

      -     That we have received all the documents we requested, including the
            signed Schedule and Delivery and Acceptance Certificate.

      -     That there has been no material adverse change in your financial
            condition, business, operations or prospects, or that of any
            guarantor, from the condition that you disclosed to us in your
            application for credit.

      3.    RENT

      -     The rent is indicated on the Schedule. The rent is payable
            periodically in advance from time to time (for example, monthly).
            You agree that you owe us the total of all of these rent payments
            over the Term of the Schedule.

      -     The first rent payment is due at the beginning of the Term or at a
            later date that we agree to in writing. Subsequent rent payments are
            due on the same day of each successive period until you pay us in
            full all of the rent and any other charges or expenses you owe us.

      -     If the first rent payment is due later than the beginning of the
            Term, you will also pay us interim rent on the first rent payment
            date. The interim rent will be for the period from the beginning of
            the Term until the date that the first rent payment is due. Interim
            rent will be calculated at the same rate as the regular rent
            payment, but on a daily basis for the number of days for which
            interim rent is due.

      -     YOUR OBLIGATION TO PAY US ALL RENT IS ABSOLUTE AND UNCONDITIONAL.
            YOU ARE NOT EXCUSED FROM PAYING THE RENT, IN


<PAGE>   2
            FULL, FOR ANY REASON. YOU AGREE THAT YOU HAVE NO DEFENSE FOR FAILURE
            TO PAY THE RENT AND YOU WILL NOT MAKE ANY COUNTERCLAIMS OR SETOFFS
            TO AVOID PAYING THE RENT.

      4.    NON-CANCELABLE LEASE. YOU AGREE THAT YOU MAY NOT CANCEL OR TERMINATE
            THIS LEASE OR ANY SCHEDULE.

      5.    PROTECTION OF OUR INTEREST IN THE EQUIPMENT; FEES.

      -     The Equipment is our property. It will remain our property. You will
            not own the Equipment unless the Schedule gives you an option to
            purchase the Equipment and you have exercised that option and paid
            us in full for the Equipment and any other amounts you may owe us.
            If we request, you will put labels supplied by us stating "PROPERTY
            OF FINOVA" on the Equipment where they are clearly visible.

      -     You give us permission to add to this Lease or any Schedule the
            serial numbers and other information about the Equipment.

      -     While this Lease is intended to be a lease (and not a loan), you
            grant us a security interest in the Equipment to protect our
            interest in the Equipment if this Lease is later determined to be a
            security agreement. You give us permission to file this Lease or a
            Uniform Commercial Code financing statement, at your expense, in
            order to perfect this security interest. You also give us permission
            to sign your name on the Uniform Commercial Code financing
            statements where this is permitted by law.

      -     You will pay our cost to do searches for other filings or judgments
            against you or your affiliates. You will also pay any filing,
            recording or stamp fees or taxes resulting from filing this Lease or
            a Uniform Commercial Code financing statement. You will also pay our
            fees in effect from time to time for documentation, administration
            and Termination of this Lease.

      -     At your expense, you will defend our ownership rights in the
            Equipment against, and keep the Equipment free of, any legal
            process, liens, security interests, attachments, levies and
            executions. You will give us immediate written notice of any legal
            process, liens, attachments, levies or executions, and you will
            indemnify us against any loss that results to us from these causes.

      -     You will notify us at least 15 days before you change the address of
            your principal executive office.

      -     You will promptly sign and return additional documents that we may
            request in order to protect our interest in the Equipment.

      -     The Equipment is personal property and will remain personal
            property. You will not incorporate it into real estate and will not
            do anything that will cause the Equipment to become part of real
            estate or a fixture.

      6.    CARE, USE, LOCATION AND ALTERATION OF THE EQUIPMENT

      -     You will make sure that the Equipment is maintained in good
            operating condition, and that it is serviced, repaired and
            overhauled when this is necessary to keep the Equipment in good
            operating condition. All maintenance must be done according to the
            Supplier's or Manufacturer's requirements or recommendations. All
            maintenance must also comply with any legal or regulatory
            requirements.

      -     You will maintain service logs for the Equipment, if applicable, and
            permit us to inspect the Equipment, the service logs and service
            reports. You give us permission to make copies of the service logs
            and service reports.

      -     We will give you prior notice if we, or our agent, want to inspect
            the Equipment or the service logs or service reports. We may inspect
            it during regular business hours. If we find during an inspection
            that you are not complying with this Lease, you will pay our travel,
            meals and lodging costs, our salary costs, and the costs and fees of
            our agents for reinspection. You will promptly cure any problems
            with the Equipment that are discovered during our inspection.

      -     You will use the Equipment only for business purposes. You will obey
            all legal and regulatory requirements in your use of the Equipment.



                                        2


<PAGE>   3
      -     You will make all additions, modifications and improvements to the
            Equipment that are required by law or government regulation.
            Otherwise, you will not alter the Equipment without our written
            permission. You will replace all worn, lost, stolen or destroyed
            parts of the Equipment with replacement parts that are as good or
            better than the original parts. The new parts will become our
            property upon replacement.

      -     You will not remove the Equipment from the location indicated in the
            Schedule without our written permission.

      7.    RETURN OF EQUIPMENT. Unless otherwise stated in the Schedule:

      -     You must give us written notice at least 60 days before the end of
            the Term if you want to purchase the equipment from us (assuming the
            Schedule provides you with an option to purchase the Equipment).

      -     You must give us written notice at least 60 days before the end of
            the Term if you want to return the Equipment to us.

      -     If you do not give us written notice at least 60 days before the end
            of the Term either that you want to purchase or that you want to
            return the Equipment, you will continue to rent the Equipment and
            this Lease and the Schedule will be automatically extended until 120
            days after we receive your notice. The rent will be the fair market
            rental value of the Equipment, as determined by us. Unless we notify
            you otherwise, the fair market rental value will not exceed the rent
            then being charged under this Lease and the Schedule.

      -     If you do give us 60 days written notice that you want to purchase
            the Equipment but you do not pay us the purchase price, you will
            continue to rent the Equipment. The rent will be the fair market
            rental value of the Equipment, as determined by us. You will
            continue to pay us this rent until you have paid the purchase price
            for the Equipment. The rent payments will not be credited to the
            purchase price.

      -     If you do give us 60 days written notice that you want to return the
            Equipment to us, but you do not return the Equipment in compliance
            with the return conditions contained in the next paragraph, you will
            continue to rent the Equipment. The rent will be the fair market
            rental value of the Equipment, as determined by us. You will
            continue to pay us this rent until you have returned the Equipment
            to us in compliance with these return conditions.

      -     Return conditions: - You will return the Equipment, freight and
            insurance prepaid by you, to us at a location we request in the
            United States of America. It will be returned in good operating
            condition, as required by section 6 above. The Equipment will not be
            subject to any liens when it is returned.

            -     You will pack or crate the Equipment for shipping in the
                  original containers, or comparable ones. You will do this
                  carefully and follow all recommendations of the Supplier and
                  the Manufacturer as to packing or crating.

            -     You will also return to us the plans, specifications,
                  operating manuals, software documentation, discs, warranties
                  and other documents furnished by the Manufacturer or Supplier.
                  You will also return to us all service logs and service
                  reports, as well as all written materials that you may have
                  concerning the maintenance and operation of the Equipment.

            -     At our request, you will provide us with up to 60 days free
                  storage of the Equipment at your location, and upon prior
                  notice and during normal business hours (except in a case of
                  an Event of Default in which case no notice is due) you will
                  let us (or our agent) have access to the Equipment in order to
                  inspect it and sell it.

            -     You will pay us what it costs us to repair the Equipment if
                  you do not return it in the required condition.

      8.    RISK OF LOSS

      -     You have the complete risk of loss or damage to the Equipment. Loss
            or damage to the Equipment will not relieve you of your obligation
            to pay rent.

      -     If any Equipment is lost or damaged, you have two choices (although
            if you are in default under this Lease, we and not you will have the
            two options). The choices are:

      (1)   Repair or replace the damaged or lost Equipment so that, once again,
            we own Equipment in good operating condition and have clear title to
            it.

      (2)   Pay us the present value (as of the date of payment) of the
            remaining rent payments and our residual interest in the Equipment.
            We will calculate the present value using a discount rate of five
            (5%) percent per year. Once you have paid us this amount and any
            other amount that you may owe us, you (or your insurer) may keep the
            Equipment for salvage purposes, on an "AS IS, WHERE IS" basis.

      9.    INSURANCE

      -     Until you have properly returned the Equipment to us, you will keep
            it insured. The amount of the insurance, the coverage, and the
            insurance company must be acceptable to us.

      -     If you do not provide us with written evidence of insurance that is
            acceptable to us, we may buy the insurance ourselves, at your
            expense. You will promptly pay us the cost of this insurance. We
            have no obligation to purchase any insurance. Any insurance that we
            purchase will be our insurance, and not yours, and may insure the
            Equipment beyond the end of the Term.

      -     Insurance proceeds may be used to repair or replace damaged or lost
            Equipment or to pay us the present value of the rent and our
            residual interest in the Equipment. (See section 8, "Risk of Loss",
            above.)

      -     You appoint us as your "attorney-in-fact" to make claims under the
            insurance policies, to receive payments under the insurance
            policies, and to endorse your name on all documents, checks or
            drafts relating to insurance claims for Equipment.

      10.   TAXES

      -     You will pay all sales, use, excise, stamp, documentary and ad
            valorem taxes, license and registration fees, assessments, fines,
            penalties and similar charges imposed on the ownership, possession,
            use or lease of the Equipment.

      -     You will pay all taxes (other than our federal or state net income
            taxes) imposed on you or on us or the rent payments.

      -     You will reimburse us for any of these taxes that we pay or advance.

      -     Unless we notify you otherwise, we will file and pay for any
            personal property taxes on the Equipment. You will reimburse us for
            the full amount of these taxes, without regard to early payment
            discount. We may estimate the amount of these taxes in advance and
            bill you periodically in advance for these taxes.

      11.   INDEMNITY

      -     You will indemnify us, defend us and hold us harmless. This applies
            to any and all claims, expenses and attorney's fees concerning or
            arising from the Equipment, this Lease, or any Schedule. It includes
            any claims concerning the manufacture, selection, delivery,
            possession, use, operation or return of the Equipment, excluding
            claims arising out of our gross negligence or willful misconduct.

      -     This obligation of yours to indemnify us continues even after the
            Term is over.

      12.   DEFAULT

      You are in default if any of the following happens:

      -     You do not pay us, within five (5) days of when it is due, any rent
            payment or other payment that you owe us under this Lease, any
            Schedule, or any other lease, loan or other financial arrangement
            that you have with us.

      -     Any of the financial information that you give us is not true and
            complete, or you fail to tell us



                                       4

<PAGE>   5
            anything that would make the financial information misleading in any
            material respect.

      -     You do something you are not permitted to do, or you fail to do
            anything that is required of you, under this Lease, any Schedule or
            any other lease, loan or other financial arrangement that you have
            with us, which continues uncured for thirty (30) days after written
            notice by us to you.

      -     An event of default occurs for any other lease, loan or obligation
            of yours (or any guarantor) that exceeds $50,000.

      -     You or any guarantor file bankruptcy, or involuntary bankruptcy is
            filed against you or any guarantor and is not dismissed within 60
            days.

      -     You or any guarantor are subject to any other insolvency proceeding
            other than bankruptcy (for example, a receivership action or an
            assignment for benefit of creditors) and such proceeding that is
            involuntary is not dismissed within 60 days.

      -     Without our permission, which shall not be unreasonably withheld or
            delayed you sell all or a substantial part of its assets, merge or
            consolidate, or a majority of your voting stock or interests (or any
            guarantor's voting stock or interests) is transferred.

      -     There is a material adverse change in your financial condition,
            business, operations or prospects, or that of any guarantor, from
            the condition that you disclosed to us in your application for
            credit.

      13.   REMEDIES, DEFAULT INTEREST, LATE FEES

      If you are in default we may exercise one or more of our "remedies." Each
      of our remedies is independent. We may exercise any of our remedies, all
      of our remedies or none of our remedies. We may exercise them in any order
      we choose. Our exercise of any remedy will not prevent us from exercising
      any other remedy or be an "election of remedies." If we do not exercise a
      remedy, or if we delay in exercising a remedy, this does not mean that we
      are forgiving your default or that we are giving up our right to exercise
      the remedy. Our remedies allow us to do one or more of the following:

      -     Require you to immediately pay us all rent for the entire Term for
            any or all Schedules.

      -     Require you to immediately pay us all amounts that you are required
            to pay us for the entire Term of any other leases, loans or other
            financial arrangements that you have with us.

      -     Sue you for all rent and other amounts you owe us plus the greater
            of (1) the actual residual value of the Equipment or (2) the
            residual value we assumed when we leased it to you. Future rent and
            residual value will be discounted to present value using a discount
            rate of five (5%) percent per year.

      -     Require you at your expense to assemble the Equipment at a location
            we request in the United States of America.

      -     Remove and repossess the Equipment from where it is located, without
            demand or notice, or make the Equipment inoperable. We have your
            permission to remove any physical obstructions to removal of the
            Equipment. We may also disconnect and separate all Equipment from
            other property. No court order, court hearing or "legal process"
            will be required for us to repossess the Equipment. You will not be
            entitled to any damages resulting from removal or repossession of
            the Equipment. We may use, ship, store, repair or lease any
            Equipment that we repossess. We may sell any repossessed Equipment
            at private or public sale. You give us permission to show the
            Equipment to buyers at your location free of charge during normal
            business hours. If we do this, we do not have to remove the
            Equipment from your location. If we repossess the Equipment and sell
            it, we will give you credit for the net sale price, after
            subtracting our costs of repossessing and selling the Equipment. If
            we rent the Equipment to somebody else, we will give you credit for
            the net rent received, after subtracting our costs of repossessing
            and renting the Equipment, but the credit will be discounted to
            present value using the discount rate that we used in calculating
            your rental payment under the Schedule for the Equipment. The credit
            will be applied against what you owe us under this Lease, the
            Schedules and any other leases, loans or other financial
            arrangements that you have with us. If the credit exceeds the amount
            you owe under this Lease,



                                       5
<PAGE>   6
            the Schedules and any other leases, loans or other financial
            arrangements that you have with us, we will refund the amount of the
            excess to you.

      -     You will also pay us the following:

      -     All our expenses of enforcing our remedies. This includes all our
            expenses to repossess, store, ship, repair and sell the Equipment.

      -     Our reasonable attorney's fees and expenses.

      -     Default interest on everything you owe us from the date of your
            default to the date on which we are paid in full. The "default
            interest rate" will be one and one-half (1.5%) percent per month. If
            this interest rate exceeds the highest legal interest rate, you will
            only be required to pay us default interest at the highest legal
            interest rate.

      You realize that the damages we could suffer as a result of your default
      are very uncertain. You also realize that the value of an unexpired lease
      Term is difficult or impossible to calculate. This is why we have agreed
      with you in advance on the discount rates and default interest rate to be
      used in calculating the payments you will owe us if you default. You agree
      that, for these reasons, the payments you will owe us if you default are
      "agreed" or "liquidated" damages. You understand that these payments are
      not "penalties" or "forfeitures."

      You will pay us a late fee whenever you pay any amount that you owe us
      more than ten (10) days after it is due. You will pay the late fee within
      one month after the late payment was originally due. The late fee will be
      five (5%) percent of the late payment. If this exceeds the highest legal
      amount we can charge you; you will only be required to pay the highest
      legal amount. The late fee is intended to reimburse us for our collection
      costs that are caused by late payment. It is charged in addition to all
      other amounts you are required to pay us, including default interest.

      14.   PERFORMING YOUR OBLIGATIONS IF YOU DO NOT

      If you do not perform one or more of your obligations under this Lease or
      a Schedule, we may perform it for you. We will notify you in writing at
      least ten (10) days before we do this. We do not have to perform any of
      your obligations for you. If we do choose to perform them, you will pay us
      all of our expenses to perform the obligations. You will also reimburse us
      for any money that we advance to perform your obligations, together with
      interest at the default interest rate on that amount. This will be
      additional "rent" that you will owe us and you will pay it at the same
      time that your next rent payment is due.

      15.   ASSIGNMENT

      WE MAY ASSIGN THIS LEASE OR ANY SCHEDULE OR ANY RENT PAYMENTS WITHOUT YOUR
      PERMISSION.

      WE MAY GRANT A SECURITY INTEREST IN THE EQUIPMENT WITHOUT YOUR PERMISSION.

      THE PERSON TO WHOM WE ASSIGN IS CALLED THE "ASSIGNEE." THE ASSIGNEE WILL
      NOT HAVE ANY OF OUR OBLIGATIONS UNDER THIS LEASE. YOU WILL NOT BE ABLE TO
      RAISE ANY DEFENSE, COUNTERCLAIM OR OFFSET AGAINST THE ASSIGNEE.

      AFTER ASSIGNMENT YOU MAY "QUIETLY ENJOY" THE USE OF THE EQUIPMENT SO LONG
      AS YOU ARE NOT IN DEFAULT.

      UNLESS YOU RECEIVE OUR WRITTEN PERMISSION, YOU MAY NOT ASSIGN OR TRANSFER
      YOUR RIGHTS UNDER THIS LEASE OR ANY SCHEDULE. YOU ALSO ARE NOT ALLOWED TO
      SUBLET THE EQUIPMENT OR LET ANYBODY ELSE USE IT UNLESS WE GIVE YOU OUR
      WRITTEN PERMISSION.

      16.   UNIFORM COMMERCIAL CODE DISCLAIMERS OF WARRANTIES AND WAIVERS

      WE DID NOT MANUFACTURE OR SUPPLY THE EQUIPMENT. WE ARE NOT A DEALER IN THE
      EQUIPMENT. INSTEAD, YOU CHOSE THE EQUIPMENT.

      WE DO NOT MAKE ANY WARRANTY AS TO THE EQUIPMENT. WE DO NOT MAKE ANY
      WARRANTY AS TO "MERCHANTABILITY" OR "SUITABILITY" OR "FITNESS FOR A
      PARTICULAR PURPOSE" OR

      "NONINFRINGEMENT" OF ANY PATENT, COPYRIGHT OR OTHER INTELLECTUAL PROPERTY
      RIGHT.

      WE WILL NOT BE RESPONSIBLE FOR ANY LOSS, DAMAGE, OR INJURY TO YOU OR
      ANYBODY ELSE AS A RESULT OF ANY DEFECTS, HIDDEN OR OTHERWISE, IN THE
      EQUIPMENT UNDER "STRICT LIABILITY" LAWS OR ANY OTHER LAWS.

      WE WILL NOT BE RESPONSIBLE FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL
      DAMAGES, LOSS OF PROFITS OR GOODWILL.

      WE MAKE NO WARRANTY AS TO THE TREATMENT OF THIS LEASE FOR TAX OR
      ACCOUNTING PURPOSES.

      If the Equipment is unsatisfactory, you will continue to pay us all rent
      and other amounts you are required to pay us. You must seek repair or
      replacement of the Equipment solely from the Manufacturer or Supplier and
      not from us. You may use our rights under any Manufacturer or Supplier
      warranties on the Equipment to get it repaired or replaced. Neither the
      Manufacturer nor the Supplier is our "agent," so they cannot speak for us
      and they are not allowed to make any changes in this Lease or any
      Schedule, or give up any of our rights.

      17. UNIFORM COMMERCIAL CODE ARTICLE 2A PROVISIONS.

      This Lease is a "Finance Lease" under Article 2A of the Uniform Commercial
      Code. You agree that (a) we have advised you of the identity of the
      Supplier, (b) you may have rights under the "supply contract" under which
      we are purchasing the Equipment from the Supplier and (c) you may contact
      the Supplier for a description of these rights.

      YOU WAIVE ANY AND ALL OF YOUR RIGHTS AND REMEDIES UNDER ARTICLE 2A OF THE
      UNIFORM COMMERCIAL CODE, INCLUDING SECTIONS 2A-508 THROUGH 2A-522 OF THE
      UNIFORM COMMERCIAL CODE.

      THEORIES, INCLUDING CONTRACT, TORT AND STRICT LIABILITY. YOU CONSENT TO

      MARICOPA COUNTY, ARIZONA, IS AN "INCONVENIENT FORUM" OR THAT IT IS NOT A
      PROPER "VENUE."

      19.   INFORMATION SUPPLIED BY YOU AND ANY GUARANTOR

      -     All financial information and other information that you or any
            guarantor have given us is true and complete. You or any guarantor
            have not failed to tell us anything that would make the financial
            information misleading. There has been no material adverse change in
            your financial condition, business, operations or prospects, or the
            financial condition of any guarantor, from the financial condition
            that you disclosed to us in your application for credit.



                                       7
<PAGE>   8
      -     You have supplied us with information about the Equipment. You
            promise to us that the amount we are paying for the Equipment is no
            more than the fair and usual price for this kind of Equipment,
            taking into account any discounts, rebates and allowances that you
            or any affiliate of yours may have been given for the Equipment.

      -     During the Term you will promptly give copies of any filings you
            make with the Securities and Exchange Commission (SEC). You and any
            guarantor will also provide us with the following financial
            statements:

      -     Quarterly balance sheet and statements of earnings and cash flow -
            within 45 days after the end of your first three fiscal quarters in
            each fiscal year. These will be certified by your chief financial
            officer and accompanied by a certificate of your chief financial
            officer stating that no default exists, or, if he or she cannot
            certify this because a default does exist, he or she must specify in
            reasonable detail the nature of the default.

      -     Annual balance sheet and statements of earnings and cash flow -
            within 120 days after the end of each fiscal year. These will be
            audited by independent auditors acceptable to us and will be
            accompanied by a certificate executed by your Chief Financial
            Officer stating that you have complied with all covenants contained
            in the Lease and that there are no events of default thereunder
            ("the Compliance Certificate"). Their audit report must be
            unqualified or otherwise acceptable to FINOVA.

      These financial statements will be prepared according to generally
      accepted accounting principles, consistently applied.

      All financial statements and SEC filings that you or any guarantor provide
      us will be true and complete. They will not fail to tell us anything that
      would make them misleading.

      20.   NOTICES

      service, or by fax. Notice will be sent to your address below your

Comerica

                               SECURITY AGREEMENT

As of September 16, 1999, for value received, the undersigned ("Debtor") grants
to Comerica Bank-California ("Bank"), a California banking corporation, a
continuing security interest in the collateral (as defined below) to secure
payment when due, whether by stated maturity, demand acceleration or otherwise,
of all existing and future indebtedness ("Indebtedness") ?? the Bank of Avanex
Corporation ("Borrower") and/or Debtor. Indebtedness includes without limit any
and all obligations or liabilities of the Borrower and/or Debtor to the Bank,
whether absolute or contingent, direct or indirect, voluntary or involuntary,
liquidated or unliquidated, joint or several, known or unknown; any and all
obligations or liabilites for which the Borrower and/or Debtor would otherwise
be liable to the Bank were it not for the invalidity or unenforceability of them
by reason of any bankruptcy, insolvency or other law, or for any other reason;
any and all amendments, modifications, renewals and/or extensions of any of the
above; all costs incurred by Bank in establishing, determining, continuing, or
defending the validity or priority of its security interest, or in pursuing its
rights and remedies under this Agreement or under any other agreement between
Bank and Borrower and/or Debtor or in connection with any proceeding involving
Bank as a result of any financial accommodation to Borrower and/or Debtor; and
all other costs of collecting indebtedness, including without limit attorney
fees. Debtor agrees to pay Bank all such costs incurred by the Bank, immediately
upon demand, and until paid all costs shall bear interest at the highest per
annum rate applicable to any of the indebtedness, but not in excess of the
maximum rate permitted by law. Any reference in this Agreement to attorney fees
shall be deemed a reference to reasonable fees, costs, and expenses of both
in-house and outside counsel and paralegals, whether or not a suit or action is
instituted and to court costs if a suit or action is instituted, and whether
attorney fees or court costs are incurred at the trial court level, on appeal,
in a bankruptcy, administrative or probate proceeding or otherwise.

1.      Collateral shall mean all of the following property Debtor now or later
        owns or has an interest in, wherever located:

        *       specific items listed below and/or on attached Schedule A, if
                any, is/are also included in Collateral: A Certificate of
                Deposit (#850750000070251) dated, in the name of Avanex
                Corporation, in the amount of $800,000.00 and any and all
                subsequent renewals thereof.

        *       all goods, instruments, documents, policies and certificates of
                insurance, deposits, money or other property (except real
                property which is not a fixture) which are now or later in
                possession of Bank, or as to which Bank now or later controls
                possession by documents or otherwise, and

        *       all additions, attachments, accessions, parts, replacements,
                substitutions, renewals, interest, dividends, distributions,
                rights of any kind (including but not limited to stock splits,
                stock rights, voting and preferential rights), products, and
                proceeds of or pertaining to the above including, without limit,
                cash or other property which were proceeds and are recovered by
                a bankruptcy trustee or otherwise as a preferential transfer by
                Debtor.

2.      Warranties, Covenants and Agreements. Debtor warrants, covenants and
        agrees as follows:

        2.1     Debtor shall furnish to Bank, in form and at intervals as Bank
                may request, any information Bank may reasonably request and
                allow Bank to examine, inspect, and copy any of Debtor's books
                and records. Debtor shall, at the request of Bank, mark its
                records and the Collateral to clearly indicate the security
                interest of Bank under this Agreement.

        2.2     At the time any Collateral becomes, or is represented to be,
                subject to a security interest in favor of Bank, Debtor shall be
                deemed to have warranted that (a) Debtor is the lawful owner of
                the Collateral and has the right and authority to subject it to
                a security interest granted to Bank; (b) none of the Collateral
                is subject to any security interest other than that in favor of
                Bank and there are no financing statements on file, other than
                in favor of Bank; and (c) Debtor acquired its rights in the
                Collateral in the ordinary course of its business.

        2.3     Debtor will keep the Collateral free at all times from all
                claims, liens, security interests and encumbrances other than
                those in favor of Bank. Debtor will not, without the prior
                written consent of Bank, sell, transfer or lease, or permit to
                be sold, transferred or leased, any or all of the Collateral,
                except (where inventory is pledged as Collateral) for inventory
                in the ordinary course of its business and will not return any
                Inventory to its supplier. Bank or its representatives may at
                all reasonable times inspect the Collateral and may enter upon
                all premises where the Collateral is kept or might be located.

        2.4     Debtor will do all acts and will execute or cause to be executed
                all writings requested by Bank to establish, maintain and
                continue a perfected and first security interest of Bank in the
                Collateral. Debtor agrees that Bank has no obligation to acquire
                or perfect any lien on or security interest in any asset(s),
                whether realty or personalty, to secure payment of the
                Indebtedness, and Debtor is not relying upon assets in which the
                Bank may have a lien or security interest for payment of the
                Indebtedness.

        2.5     Debtor will pay within the time that they can be paid without
                interest or penalty all taxes, assessments and similar charges
                which at any time are or may become a lien, charge, or
                encumbrance upon any Collateral, except to the extent contested
                in good faith and bonded in a manner satisfactory to Bank. If
                Debtor fails to pay any of these taxes, assessments, or other
                charges in the time provided above, Bank has the option (but not
                the obligation) to do so and Debtor agrees to repay all amounts
                so expanded by Bank immediately upon demand, together with
                interest at the highest lawful default rate which could be
                charged by Bank on any Indebtedness.

        2.6     Debtor will keep the Collateral in good condition and will
                protect it from loss, damage, or deterioration from any cause.
                Debtor has and will maintain at all times (a) with respect to
                the Collateral, insurance under an "all risk" policy against
                fire and other risks customarily insured against; and (b) public
                liability insurance and other insurance as may be required by
                law or reasonably required by Bank, all of which insurance shall
                be in amount, form and content, and written by companies as may
                be satisfactory to Bank, containing a Lender's loss payable
                endorsement acceptable to Bank. Debtor will deliver to Bank
                immediately upon demand evidence satisfactory to Bank that the
                required insurance has been procured. If Debtor fails to
                maintain satisfactory insurance, Bank has the option (but not
                the obligation) to do so and Debtor agrees to repay all amounts
                so expended by Bank immediately upon demand, together with
                interest at the highest lawful default rate which could be
                charged by Bank on any indebtedness.

        2.7     If Accounts Receivable are pledged as Collateral under this
                Agreement, then on each occasion on which Debtor evidences to
                Bank the account balances on and the nature and extent of the
                Accounts Receivable, Debtor shall be deemed to have warranted
                that except as otherwise indicated (a) each of those Accounts
                Receivable is valid and enforceable without performance by
                Debtor of any act; (b) each of those account balances are in
                fact owing, (c) there are no setoffs, recoupments, credits,
                contra accounts, counterclaims or defenses against any of those
                Accounts Receivable, (d) as to any Accounts Receivable
                represented by a note, trade acceptance, draft or other
                instrument or by any chattel paper or document, the same have
                been endorsed and/or delivered by Debtor to Bank, (e) Debtor has
                not received with respect to any Account Receivable, any notice
                of the death of the related account debtor, nor of the
                dissolution, liquidation, termination of existence, insolvency,
                business failure, appointment of a receiver for, assignment for
                the benefit of creditors by, or filing of a petition in
                bankruptcy by or against, the account debtor, and (f) as to each
                Account Receivable, the account debtor is not an affiliate of
                Debtor, the United States of America or any department, agency
                or instrumentality of it, or a citizen or resident of any
                jurisdiction outside of the United States. Debtor will do all
                acts and will execute all writings requested by Bank to perform,
                enforce performance of, and collect all Accounts Receivable.
                Debtor shall neither make nor permit any modification,
                compromise or substitution for any Account Receivable without
                the prior written consent of Bank. Debtor shall, at Bank's
                request, arrange for verification of Accounts Receivable
                directly with account debtors or by other methods acceptable to
                Bank.

        2.8     Debtor at all times shall be in strict compliance with all
                applicable laws, including without limit any laws,


<PAGE>   2
                ordinances, directives, orders, statutes, or regulations an
                object of which is to regulate or improve health, safety, or the
                environment ("Environmental Laws").

        2.9     If marketable securities are pledged as Collateral under this
                Agreement and if at any time the outstanding principal balance
                of the Indebtedness exceeds N/A of the value of the Collateral,
                as such value is determined from time to time by Bank (herein
                called the "Margin Requirement"), Debtor shall immediately pay
                or cause to be paid to Bank an amount sufficient to reduce the
                Indebtedness such that the remaining principal outstanding
                thereunder is equal to or less than the Margin Requirement. Bank
                shall apply payments made under this paragraph in payment of the
                Indebtedness in such order and manner of application as Bank in
                its sole discretion elects. In the alternative, Debtor may
                provide or cause to be provided to Bank additional collateral in
                the form of cash or other property acceptable to Bank and with a
                value, as determined by Bank, that when added to the Collateral
                will constitute compliance with the Margin Requirement.

        2.10    If Bank, acting in its sole discretion, redelivers Collateral to
                Debtor or Debtor's designee for the purpose of (a) the ultimate
                sale or exchange thereof; or (b) presentation, collection,
                renewal, or registration of transfer thereof; or (c) loading,
                unloading, storing, shipping, transshipping, manufacturing,
                processing or otherwise dealing with it preliminary to sale or
                exchange; such redelivery shall be in trust for the benefit of
                Bank and shall not constitute a release of Bank's security
                interest in it or in the proceeds or products of it unless Bank
                specifically so agrees in writing. If Debtor requests any such
                redelivery, Debtor will deliver with such request a duly
                executed financing statement in form and substance satisfactory
                to Bank. Any proceeds of Collateral coming into Debtor's
                possession as a result of any such redelivery shall be held in
                trust for Bank and immediately delivered to Bank for application
                on the Indebtedness. Bank may (in its sole discretion) deliver
                any or all of the Collateral to Debtor, and such delivery by
                Bank shall discharge Bank from all liability or responsibility
                for such Collateral. Bank, at its option, may require delivery
                of any Collateral to Bank at any time with such endorsements or
                assignments of the Collateral as Bank may request.

        2.11    At any time and without notice, Bank may, as to Collateral other
                than Equipment, Fixtures or Inventory, (a) cause any or all of
                such Collateral to be transferred to its name or to the name of
                its nominees; (b) receive or collect by legal proceedings or
                otherwise all dividends, interest, principal payments and other
                sums and all other distributions at any time payable or
                receivable on account of such Collateral, and hold the same as
                Collateral, or apply the same to the Indebtedness, the manner
                and distribution of the application to be in the sole discretion
                of Bank; (c) enter into any extension, subordination,
                reorganization, deposit, merger or consolidation agreement or
                any other agreement relating to or affecting such Collateral,
                and deposit or surrender control of such Collateral, and accept
                other property in exchange for such Collateral and hold or apply
                the property or money so received pursuant to this Agreement.

        2.12    Bank may assign any of the Indebtedness and deliver any or all
                of the Collateral to its assignee, who then shall have with
                respect to Collateral so delivered all the rights and powers of
                Bank under this Agreement, and after that Bank shall be fully
                discharged from all liability and responsibility with respect to
                Collateral so delivered.

        2.13    Debtor delivers this Agreement based solely on Debtor's
                independent investigation of (or decision not to investigate)
                the financial condition of Borrower and is not relying on any
                information furnished by Bank. Debtor assumes full
                responsibility for obtaining any further information concerning
                the Borrower's financial condition, the status of the
                Indebtedness or any other matter which the undersigned may deem
                necessary or appropriate now or Later. Debtor waives any duty on
                the part of Bank, and agrees that Debtor is not relying upon nor
                expecting Bank to disclose to Debtor any fact now or later known
                by Bank, whether relating to the operations or condition of
                Borrower, the existence, Liabilities or financial condition of
                any guarantor of the Indebtedness, the occurrence of any default
                with respect to the Indebtedness, or otherwise, notwithstanding
                any effect such fact may have upon Debtor's risk or Debtor's
                rights against Borrower. Debtor knowingly accepts the full range
                of risk encompassed in this Agreement, which risk includes
                without Limit the possibility that Borrower may incur
                Indebtedness to Bank after the financial condition of Borrower,
                or Borrower's ability to pay debts as they mature, has
                deteriorated.

        2.16    Debtor shall defend, indemnify and hold harmless Bank, its
                employees, agents, shareholders, affiliates, officers, and
                directors from and against any and all claims, damages, fines,
                expenses, liabilities or causes of action of whatever kind,
                including without limit consultant fees, legal expenses, and
                attorney fees, suffered by any of them as a direct or indirect
                result of any actual or asserted violation of any law,
                including, without limit, Environmental Laws, or of any
                remediation relating to any property required by any law,
                including without limit Environmental Laws.

3.      Collection of Proceeds.

        3.1     Debtor agrees to collect and enforce payment of all Collateral
                until Bank shall direct Debtor to the contrary. Immediately upon
                notice to Debtor by Bank and at all times after that, Debtor
                agrees to fully and promptly cooperate and assist Bank in the
                collection and enforcement of all Collateral and to hold in
                trust for Bank all payments received in connection with
                Collateral and from the sale, lease or other disposition of any
                Collateral, all rights by way of suretyship or guaranty and all
                rights in the nature of a lien or security interest which Debtor
                now or later has regarding Collateral. Immediately upon and
                after such notice, Debtor agrees to (a) endorse to Bank and
                immediately deliver to Bank all payments received on Collateral
                or from the sale, lease or other disposition of any Collateral
                or arising from any other rights or interests of Debtor in the
                Collateral, in the form received by Debtor without commingling
                with any other funds, and (b) immediately deliver to Bank all
                property in Debtor's possession or later coming into Debtor's
                possession through enforcement of Debtor's rights or interests
                in the Collateral. Debtor irrevocably authorizes Bank or any
                Bank employee or agent to endorse the name of Debtor upon any
                checks or other items which are received in payment for any
                Collateral, and to do any and all things necessary in order to
                reduce these items to money. Bank shall have no duty as to the
                collection or protection of Collateral or the proceeds of it,
                nor as to the preservation of any related rights, beyond the use
                of reasonable care in the custody and preservation of Collateral
                in the possession of Bank. Debtor agrees to take all steps
                necessary to preserve rights against prior parties with respect
                to the Collateral. Nothing in this Section 3.1 shall be deemed a
                consent by Bank to any sale, lease or other disposition of any
                Collateral.

        3.2     If Accounts Receivable are pledged as Collateral, this Section
                3.2 shall be applicable and Debtor agrees that immediately upon
                Bank's request (whether or not any Event of Default exists) the
                indebtedness shall be on a "remittance basis" as follows: Debtor
                shall at its sole expense establish and maintain (and Bank, at
                Bank's option, may establish and maintain at Debtor's expense):
                (a) an United States Post Office Lock box (the "Lock Box"), to
                which Bank shall have exclusive access and control. Debtor
                expressly authorizes Bank, from time to time, to remove contents
                from the Lock Box, for disposition in accordance with this
                Agreement. Debtor agrees to notify all account debtors and other
                parties obligated to Debtor that all payments made to Debtor
                agrees to payments by electronic funds transfer) shall be
                remitted, for the credit of Debtor, to the Lock Box, and Debtor
                shall include a like statement on all invoices; and (b) a
                non-interest bearing deposit account with Bank which shall be
                titled as designated by Bank (the "Cash Collateral Account") to
                which Bank shall have exclusive access and control. Debtor
                agrees to notify all account debtors and other parties obligated
                to Debtor that all payments made to Debtor by electronic funds
                transfer shall be remitted to the Cash Collateral Account, and
                Debtor, at Bank's request, shall include a like statement on all
                invoices. Debtor shall execute all documents and authorization
                as required by Bank to establish and maintain the Lock Box and
                the Cash Collateral Account.

        3.3     If Accounts Receivable are pledged as Collateral, this Section
                3.3 shall be applicable, and all items or amounts which are
                remitted to the Lock Box, to the Cash Collateral Account, or
                otherwise delivered by or for the benefit of Debtor to Bank on
                account of partial or full payment of, or with respect to, any
                Collateral shall, at Bank's option, (i) be applied to the
                payment of the Indebtedness, whether then due or not, in such
                order or at such time of application as Bank may determine in
                its sole discretion, or, (ii) be deposited to the Cash
                Collateral Account. Debtor agrees that Bank shall not be liable
                for any loss or damage which Debtor may suffer as a result of
                Bank's processing of items or its exercise of any other rights
                or remedies under this Agreement, including without Limitation
                indirect, special or consequential damages, loss of revenues or
                profits, or any claim, demand or action by any third party
                arising out of or in connection with the processing of items or
                the exercise of any other rights or remedies under this
                Agreement. Debtor agrees to indemnify and hold Bank harmless
                from and against all


<PAGE>   3
                such third party claims, demands or actions, and all related
                expenses or liabilities, including, without limitation, attorney
                fees.

                        indebtedness when due, or such portion of it as may be
                        due, by acceleration or otherwise; or

                (b)     Any failure or neglect to comply with, or breach of or

                        agreement or commitment between Borrower, Debtor, or any
                        guarantor of any of the Indebtedness ("Guarantor") and
                        Bank; or

                (c)     Any warranty, representation, financial statement, or
                        other information made, given or furnished to Bank by or
                        on behalf of Borrower, Debtor, or any Guarantor shall
                        be, or shall prove to have been, false or materially
                        misleading when made, given, or furnished; or

                (d)     Any loss, theft, substantial damage or destruction to or

                        attachment, levy, garnishment or the commencement of any
                        proceeding in connection with any Collateral or of any
                        other judicial process of, upon or in respect of
                        Borrower, Debtor, any Guarantor, or any Collateral; or

                (e)     Sale or other disposition by Borrower, Debtor, or any
                        Guarantor of any substantial portion of its assets or
                        property or voluntary suspension of the transaction of
                        business by Borrower, Debtor, or any Guarantor, or
                        death, dissolution, termination of existence, merger,
                        consolidation, insolvency, business failure, or
                        assignment for the benefit of creditors of or by
                        Borrower, Debtor, or any Guarantor; or commencement of
                        any proceedings under any state or federal bankruptcy or
                        insolvency laws or laws for the relief of debtors by or
                        against Borrower, Debtor, or any Guarantor; or the
                        appointment of a receiver, trustee, court appointee,
                        sequestrator or otherwise, for all or any part of the
                        property of Borrower, Debtor, or any Guarantor; or

                (f)     Bank deems the margin of Collateral insufficient or
                        itself insecure, in good faith believing that the
                        prospect of payment of the Indebtedness or performance
                        of this Agreement is impaired or shall fear
                        deterioration, removal, or waste of Collateral.

        4.2     Upon the occurrence of any Event of Default, Bank may at its
                discretion and without prior notice to Debtor declare any or all
                of the Indebtedness to be immediately due and payable, and shall
                have and may exercise any one or more of the following rights

                (b)     Institute legal proceedings to foreclose upon the lien
                        and security interest granted by this Agreement, to
                        recover judgment for all amounts then due and owing as
                        Indebtedness, and to collect the same out of any
                        Collateral or the proceeds of any sale of it;

                (c)     Institute legal proceedings for the sale, under the
                        Judgment or decree of any court of competent
                        jurisdiction, of any or all Collateral; and/or

                (d)     Personally or by agents, attorneys, or appointment of a
                        receiver, enter upon any premises where Collateral may
                        then be located, and take possession of all or any of it
                        and/or render it unusable; and without being responsible
                        for loss or damage to such Collateral, hold, operate,
                        sell, lease, or dispose of all or any Collateral at one
                        or more public or private sales, leasings or other
                        dispositions, at places and times and on terms and
                        conditions as Bank may deem fit, without any previous
                        demand or advertisement; and except as provided in this
                        Agreement, all notice of sale, lease or other
                        disposition, and advertisement, and other notice or
                        demand, any right or equity of redemption, and any
                        obligation of a prospective purchaser or lessee to
                        inquire as to the power and authority of Bank to sell,
                        lease, or otherwise dispose of the Collateral or as to
                        the application by Bank of the proceeds of sale or
                        otherwise, which would otherwise be required by, or
                        available to Debtor under, applicable law are expressly
                        waived by Debtor to the fullest extent permitted.

                        At any sale pursuant to this Section 4.2, whether under
                        the power of sale, by virtue of judicial proceedings or
                        otherwise, it shall not be necessary for Bank or a
                        public officer under order of a court to have present
                        physical or constructive possession of Collateral to be
                        sold. The recitals contained in any conveyances and
                        receipts made and given by Bank or the public officer to
                        any purchaser at any sale made pursuant to this
                        Agreement shall, to the extent permitted by applicable
                        law, conclusively establish the truth and accuracy of
                        the matters stated (including, without limit, as to the
                        amounts of the principal of and interest on the
                        Indebtedness, the accrual and nonpayment of it and
                        advertisement and conduct of the sale); and all
                        prerequisites to the sale shall be presumed to have been
                        satisfied and performed. Upon any sale of any
                        Collateral, the receipt of the officer making the sale
                        under judicial proceedings or of Bank shall be
                        sufficient discharge to the purchaser for the purchase
                        money, and the purchaser shall not be obligated to see
                        to the application of the money. Any sale of any
                        Collateral under this Agreement shall be a perpetual bar
                        against Debtor with respect to that Collateral.

        4.3     Debtor shall at the request of Bank, notify the account debtors
                or obligors of Bank's security interest in the Collateral and
                direct payment of it to Bank. Bank may, itself, upon the
                occurrence of any Event of Default so notify and direct any
                account debtor or obligor.

        4.4     The proceeds of any sale or other disposition of Collateral
                authorized by this Agreement shall be applied by Bank first upon
                all expenses authorized by the Uniform Commercial Code and all
                reasonable attorney fees and legal expenses incurred by Bank;
                the balance of the proceeds of the sale or other disposition
                shall be applied in the payment of the Indebtedness, first to
                interest, then to principal, then to remaining Indebtedness and
                the surplus, if any, shall be paid over to Debtor or to such
                other person(s) as may be entitled to it under applicable law.
                Debtor shall remain liable for any deficiency, which it shall
                pay to Bank immediately upon demand.

        4.5     Nothing in this Agreement is intended, nor shall it be
                construed, to preclude Bank from pursuing any other remedy
                provided by law for the collection of the Indebtedness or for
                the recovery of any other sum to which Bank may be entitled for
                the breach of this Agreement by Debtor. Nothing in this
                Agreement shall reduce or release in any way any rights or
                security interests of Bank contained in any existing agreement
                between Borrower, Debtor, or any Guarantor and Bank.

        4.6     No waiver of default or consent to any act by Debtor shall be
                effective unless in writing and signed by an authorized officer
                of Bank. No waiver of any default or forbearance on the part of
                Bank in enforcing any of its rights under this Agreement shall
                operate as a waiver of any other default or of the same default
                on a future occasion or of any rights.

        4.7     Debtor irrevocably appoints Bank or any agent of Bank (which
                appointment is coupled with an interest) the true and lawful
                attorney of Debtor (with full power of substitution) in the
                name, place and stead of, and at the expense of, Debtor:

                (a)     to demand, receive, sue for, and give receipts or
                        acquittances for any moneys due or to become due on any
                        Collateral and to endorse any item representing any
                        payment on or proceeds of the Collateral;

                (b)     to execute and file in the name of and on behalf of
                        Debtor all financing statements or other filings deemed
                        necessary or desirable by Bank to evidence, perfect, or
                        continue the security interests granted in this


<PAGE>   4
                        Agreement; and

                (c)     to do and perform any act on behalf of Debtor permitted
                        or required under this Agreement.

        4.8     Upon the occurrence of an Event of Default, Debtor also agrees,
                upon request of Bank, to assemble the Collateral and make it
                available to Bank at any place designated by Bank which is
                reasonably convenient to Bank and Debtor.

5.      Miscellaneous.

        5.1     Until Bank is advised in writing by Debtor to the contrary, all
                notices, requests and demands required under this Agreement or
                by law shall be given to, or made upon, Debtor at the first
                address indicated in Section 5.15 below.

        5.2     Debtor will give Bank not less than 90 days prior written notice
                of all contemplated changes in Debtor's name, chief executive
                office location, and/or location of any Collateral, but the
                giving of this notice shall not cure any Event of Default caused
                by this change.

        5.3     Bank assumes no duty of performance or other responsibility
                under any contracts contained within the Collateral.

        5.4     Bank has the right to sell, assign, transfer, negotiate or grant
                participations or any interest in, any or all of the
                Indebtedness and any related obligations, including without
                limit this Agreement. In connection with the above, but without
                limiting its ability to make other disclosures to the full
                extent allowable, Bank may disclose all documents and
                information which Bank now or later has relating to Debtor, the
                Indebtedness or this Agreement, however obtained. Debtor further
                agrees that Bank may provide information relating to this
                Agreement or relating to Debtor to the Bank's parent,
                affiliates, subsidiaries, and service providers.

        5.5     In addition to Bank's other rights, any indebtedness owing from
                Bank to Debtor can be set off and applied by Bank on any
                Indebtedness at any time(s) either before or after maturity or
                demand without notice to anyone.

        5.6     Debtor waives any right to require the Bank to: (a) proceed
                against any person or property; (b) give notice of the terms,
                time and place of any public or private sale of personal
                property security held from Borrower or any other person, or
                otherwise comply with the provisions of Section 9-504 of the
                Uniform Commercial Code; or (c) pursue any other remedy in the
                Bank's power. Debtor waives notice of acceptance of this
                Agreement and presentment, demand, protest, notice of protest,
                dishonor, notice of dishonor, notice of default, notice of
                intent to accelerate or demand payment of any Indebtedness, any
                and all other notices to which the undersigned might otherwise
                be entitled, and diligence in collecting any Indebtedness, and
                agree(s) that the Bank may, once or any number of times, modify
                the terms of any Indebtedness, compromise, extend, increase,
                accelerate, renew or forbear to enforce payment of any or all
                Indebtedness, or permit Borrower to incur additional
                Indebtedness, all without notice to Debtor and without affecting
                in any manner the unconditional obligation of Debtor under this
                Agreement. Debtor unconditionally and irrevocably waives each
                and every defense and setoff of any nature which, under
                principles of guaranty or otherwise, would operate to impair or
                diminish in any way the obligation of Debtor under this
                Agreement, and acknowledges that such waiver is by this
                reference incorporated into each security agreement, collateral
                assignment, pledge and/or other document from Debtor now or
                later securing the Indebtedness, and acknowledges that as of the
                date of this Agreement no such defense or setoff exists.

        5.7     Debtor waives any and all rights (whether by subrogation,
                indemnity, reimbursement, or otherwise) to recover from Borrower
                any amounts paid or the value of any Collateral given by Debtor
                pursuant to this Agreement.

        5.8     In the event that applicable law shall obligate Bank to give
                prior notice to Debtor of any action to be taken under this
                Agreement, Debtor agrees that a written notice given to Debtor
                at least five days before the date of the act shall be
                reasonable notice of the act and, specifically, reasonable
                notification of the time and place of any public sale or of the
                time after which any private sale, lease, or other dispostion is
                to be made, unless a shorter notice period is reasonable under
                the circumstances. A notice shall be deemed to be given under
                this Agreement when delivered to Debtor or when placed in an
                envelope addressed to Debtor and deposited, with postage
                prepaid, in a post office or official depository under the
                exclusive care and custody of the United States Postal Service
                or delivered to an overnight courier. The mailing shall be by
                overnight courier, certified, or first class mail.

        5.9     Notwithstanding any prior revocation, termination, surrender, or
                discharge of this Agreement in whole or in part, the
                effectiveness of this Agreement shall automatically continue or
                be reinstated in the event that any payment received or credit
                given by Bank in respect of the Indebtedness is returned,
                disagreed, or rescinded under any applicable law, including,
                without limitation, bankruptcy or insolvency laws, in which case
                this Agreement, shall be enforceable against Debtor as if the
                returned, disgorged, or rescinded payment or credit had not been
                received or given by Bank, and whether or not Bank relied upon
                this payment or credit or changed its position as a consequence
                of it. In the event of continuation or reinstatement of this
                Agreement, Debtor agrees upon demand by Bank to execute and
                deliver to Bank those documents which Bank determines are
                appropriate to further evidence (in the public records or
                otherwise) this continuation or reinstatement, although the
                failure of Debtor to do so shall not affect in any way the
                reinstatement or continuation.

        5.10    This Agreement and all the rights and remedies of Bank under
                this Agreement shall inure to the benefit of Bank's successors
                and assigns and to any other holder who derives from Bank title
                to or an interest in the Indebtedness or any portion of it, and
                shall bind Debtor and the heirs, legal representatives,
                successors, and assigns of Debtor. Nothing in this Section 5.10
                is deemed a consent by Bank to any assignment by Debtor.

        5.11    If there is more than one Debtor, all undertakings, warranties
                and covenants made by Debtor and all rights, powers and
                authorities given to or conferred upon Bank are made or given
                jointly and severally.

        5.12    Except as otherwise provided in this Agreement, all terms in
                this Agreement have the meanings assigned to them in Division 9
                (or, absent definition in Division 9, in any other Division) of
                the Uniform commercial Code, as of the date of this Agreement.
                "Uniform Commercial Code" means the California Uniform
                Commercial Code, as amended.

        5.13    No single or partial exercise, or delay in the exercise, of any
                right or power under this Agreement, shall preclude other or
                further exercise of the rights and powers under this Agreement.
                The unenforceability of any provision of this Agreement shall
                not affect the enforceability of the remainder of this
                Agreement. This Agreement constitutes the entire agreement of
                Debtor and Bank with respect to the subject matter of this
                Agreement. No amendment or modification of this Agreement shall
                be effective unless the same shall be in writing and signed by
                Debtor and an authorized officer of Bank. This Agreement shall
                be governed by and construed in accordance with the internal
                laws of the State of California, without regard to conflict of
                laws principles.

        5.14    To the extent that any of the Indebtedness is payable upon
                demand, nothing contained in this Agreement shall modify the
                terms and conditions of that Indebtedness nor shall anything
                contained in this Agreement prevent Bank from making demand,
                without notice and with or without reason, for immediate payment
                of any or all of that Indebtedness at any time(s), whether or
                not an Event of Default has occurred.

        5.15    Debtor's chief executive office is located and shall be
                maintained at 42501 Albrae Street

Dear Mr. Alessandrini:

        This letter represents your approval of the following amendment to the
Secured Promissory Note dated May 20, 1999, by and between Walter Alessandrini
and Avanex Corporation (the "Note"). Section 1 of the Note is hereby amended and
restated in its entirety to read as follows:

                "1. The principal amount of this Note and all accrued but unpaid
                interest from the date hereof shall be due on the earliest of
                (i) six months from that date on which the Borrower can sell
                shares of the Company's common stock for an amount equal to the
                principal and interest owed on this Note, so long as the sale
                complies with all applicable federal and state laws, contractual
                obligations with the Company's underwriters, Company's bylaws
                and any applicable insider trading restrictions imposed on the
                Company's employees, or (ii) the termination of Borrower's
                employment with the Company. All payments made pursuant hereto,
                regardless of when made, shall be applied first to reduce
                accrued and unpaid interest on the outstanding principal hereof
                and any remaining portion of such payments shall then be applied
                to reduce the principal hereof. All payments shall be made in
                lawful money of the United States of America. Borrower shall
                have the right to prepay at any time, and from time to time,
                without premium or penalty all or any portion of the principal
                and accrued interest hereunder."

        Please sign and date this letter to agree to the aforementioned

$300,000.00                                                  Fremont, California

                                                                    May 20, 1999

        FOR VALUE RECEIVED, the undersigned, Walter Alessandrini ("Borrower"),
hereby promises to pay to the order of Avanex Corporation, a California
corporation (the "Company"), the principal sum of Three Hundred Thousand Dollars
($300,000.00), with simple interest thereon at the rate of 4.90% per annum, at
the principal offices of the Company, upon the following terms and conditions.

        1. The principal amount of this Note and all accrued but unpaid interest
from the date hereof shall be due on the earliest of (i) the closing of the sale
by Borrower of Borrower's South Carolina home, (ii) a liquidity event of the
Company (including an initial public offering of our common stock or the sale of
substantially all of our stock or assets) or (iii) the termination of Borrower's
employment with the Company. All payments made pursuant hereto, regardless of
when made, shall be applied first to reduce accrued and unpaid interest on the
outstanding principal hereof and any remaining portion of such payments shall
then be applied to reduce the principal hereof. All payments shall be made in
lawful money of the United States of America. Borrower shall have the right to
prepay at any time, and from time to time, without premium or penalty all or any
portion of the principal and accrued interest hereunder.

        2. Borrower represents that Borrower will use the principal amount
borrowed pursuant to this Note as a down-payment on a home in the Bay Area, and
hereby grants the holder a security interest in such Bay Area home. Borrower
covenants to promptly take such action as may be required to sell Borrower's
South Carolina home and to repay all amounts of principal and interest owed
pursuant to this Note as quickly as possible.

        3. In the event that (a) Borrower defaults in the payment when due of
the principal hereof or interest hereon or the undersigned shall fail to pay
when due any other amount owing from time to time to the holder hereof, or (b)
any of the events described in Section 1 above occur, then, in any such event
and at the option of the holder of this Note, the entire principal amount then
outstanding hereunder and all accrued and unpaid interest hereon through the
date of such default or other event shall become immediately due and payable.

        4. The holder of this Note shall have full recourse against the
undersigned.

        5. Borrower hereby waives presentment, protest, demand for payment,
notice of dishonor and all other notices or demands in connection with the
delivery, acceptance, performance, default or endorsement of this Note. No
waiver by the holder hereof of any default shall be effective unless in writing
nor shall it operate as a waiver of any other default or of the same default on
a future occasion. This Note shall be binding upon the undersigned and its
successors and assigns. The undersigned agrees to pay all costs of collection of
this Note, including without limitation reasonable attorneys' fees and costs, in
the event it is not paid when due.

        6. Borrower understands that nothing in this Note modifies Borrower's
at-will status with the Company. Either the Company or Borrower can terminate
the employment relationship at any time, with or without cause.

        7. Time is of the essence of this Note. This Note may not be modified
orally, but only by a writing executed by Borrower and the holder hereof. This
Note has been made and delivered in the State of California and shall be
construed in accordance with, and all actions arising hereunder shall be
governed by, the laws of the State of California.

          (a) Position: Employment Commencement Date.  The Company shall employ

the Company through the term of this Agreement. As the Acting Chief Executive
Officer, Executive will lead the executive team of the Company. Executive agrees
not to commit to activities outside of his employment with the Company that
would require more than half of his business efforts and time. Executive will
inform the Board of any new business activities or time commitments that he
makes subsequent to the commencement of his employment with the Company.

     Executive's performance objectives include the following:

     o    Delivery of the initial components business in Fiscal Year 1998,
          including contract completing, staffing and appropriate product
          shipments and related deliverables.

     3.   At-Will Employment. Executive and the Company understand and
acknowledge that Executive's employment with the Company constitutes "at-will"
employment. Executive and the Company acknowledge that this employment
relationship may be terminated at any time, with or without good cause or for
any or no cause, at the option either of the Company or Executive.

     4.   Stock Option. The Company will grant to Executive an option for
shares of Common Stock equal to 0.75 percent of the Company's outstanding
shares of Common Stock on an as-converted and fully diluted basis assuming
issuance of all shares of Preferred Stock pursuant to the Series A, Series B
and Series C Preferred Stock Purchase Agreement dated as of February 10, 1998
and at an exercise price of the then fair market value of the Common Stock, as
determined by the Board pursuant to a Stock Option Agreement in substantially
the form attached hereto as Exhibit A.

     5.   Expenses. The Company will pay or reimburse Executive for reasonable
travel, entertainment or other expenses incurred by Executive in the furtherance
of or in connection with the performance of Executive's duties hereunder in

discussed by the Board.

     6.   No Additional Compensation. Executive shall not be entitled to any
annual salary or compensation not otherwise described in this Agreement.
Executive understands and agrees that neither his job performance nor
promotions, commendations, bonuses or the like from the Company give rise to or
in any way serve as the basis for modification, amendment, or extension, by
implication or otherwise, of this Agreement.

     7.   Enforcement. In the event of any action to enforce the terms of this
Agreement, the prevailing party in such action shall be entitled to such
party's reasonable costs and expenses of enforcement including, without
limitation, reasonable attorneys' fees.

     8.   Assignment. This Agreement shall be binding upon and inure to the
benefit of (a) the heirs, executors and legal representatives of Executive upon
Executive's death and (b) any successor of the Company. Any such successor of
the Company shall be deemed substituted for the Company under the terms of this
Agreement for all purposes. As used herein, "successor" shall include any
person, firm, corporation or other business entity which at any time, whether
by purchase, merger or otherwise, directly or indirectly acquires all or
substantially all of the assets or business of the Company. None of the rights
of Executive to receive any form of compensation payable pursuant to this
Agreement shall be assignable or transferable except through a testamentary
disposition or by the laws of descent and distribution upon the death of
Executive following termination without cause. Any attempted assignment,
transfer, conveyance or other disposition (other than as aforesaid) of any
interest in the rights of Executive to receive any form of compensation
hereunder shall be null and void.

which is attached hereto as Exhibit A).

     B.   Sublessor, as sublessor, and Assignor, as sublessee, are parties to
that certain Sublease Agreement dated October 16, 1997, as amended by an
Amendment to Sublease dated January, 1998 (as amended, the "Sublease"), a copy
of which is attached hereto as Exhibit B, concerning certain premises

     1.   Assignment. Effective as October 1, 1998 (the "Effective Date"),
          Assignor hereby assigns to Assignee all of Assignor's right, title and
          interest in the Sublease, and Assignee hereby assumes from Assignor

          make good any breach or default by Assignee with respect to any of
          Assignee's aforesaid obligations, covenants, conditions or agreements.

          Assignee harmless from and against any and all loss, claims, damages
          or expenses, including, without limitation, reasonable attorneys' fees
          and costs of suit, arising out of Assignor's occupancy of the Premises

          Assignor harmless from and against any and all loss, claims, damages
          or expense, including, without limitation, reasonable attorneys' fees
          and costs of suit, arising out of Assignee's occupancy of the Premises
          or under the Sublease, to the extent accruing on or after the

          termination of the Sublease.

          sooner termination of the Sublease.

     11.  Consent of Landlord. The effectiveness of this Assignment shall be
          contingent on the approval of Sublessor and the landlord under the

In the case of a single building Project the term "Building" as used herein
shall be synonymous with the term "Project". If the Leased Premises encompass an
entire building, then the term "Leased Premises" shall be synonymous with

thereof, is contained in Exhibit B to be attached.

        4. TERM:

                (a) The term of this Lease shall be Sixty, (60) months

behalf of Tenant, the rent under this Lease shall not commence until substantial
completion of the work described in said plans and specifications and the

completion notice from Landlord. Landlord shall have a reasonable time after
receipt of such notice in which to take such corrective action as may be
necessary and shall notify Tenant in writing as soon as it deems such corrective
action has been completed so that the Leased Premises are completed and ready
for occupancy. In the event of any dispute as to substantial completion or work

indebtedness, then Landlord shall have the right to terminate this Lease by
delivering written notice of termination to Tenant within fifteen (15) days
after such requirement is made. All rights and obligations under this Lease
shall then cease.

any improvements which Tenant may construct or install on the Leased Premises or
any signs identifying Tenant's business located on the exterior of the Building.

waivers will preclude the assignment of any such claim by way of subrogation (or
otherwise) to an insurance company (or any other person), each party hereto
hereby agrees immediately to give to its respective insurance companies written
notice of the terms of such mutual waivers and to have their respective
insurance policies properly endorsed, if necessary, to prevent the invalidation
of such insurance coverages by reason of such waivers. This provision shall be
cumulative of Paragraph 21 below.

        21. HOLD HARMLESS: Landlord shall not be liable to Tenant, Tenant's
employees, agents, invitees, licensees or visitors, or to any other person, for
any injury to person or damage to property on or about the Leased Premises or

employees, invitees, or of any other persons entering upon the Leased Premises
or the Project under express or implied invitation by Tenant. Tenant agrees to
indemnify and hold Landlord harmless from any and all loss, attorney's fees,

may incur or suffer by reason of Tenant's default or the termination of the
lease under this subparagraph, whether through inability to relet the Leased
Premises on satisfactory terms or otherwise. Tenant acknowledges that its
obligation to pay Base Rent and all additional Rent hereunder is not only
compensation for use of the Leased Premises but also compensation for sums
already expended and/or being expended by Landlord with respect to its
obligations hereunder and with respect to the Leased Premises, and Tenant
acknowledges that Tenant's default in timely payment of all sums due hereunder
shall constitute significant financial loss to Landlord. Tenant further
acknowledges that any failure to pay any sum due hereunder shall evidence
Tenant's inability to meet its debts as they become due. In such event, in
addition to Landlord's other remedies hereunder. Landlord shall be entitled to
accelerate all Base Rental remaining unpaid hereunder, the entirety of which

the Leased Premises and to reimburse Landlord on demand for any losses, costs,
and expenses, including without limitation, reconfiguration expenses, rental
concessions and other inducements to new tenants, advertising costs or broker's
commissions, which Landlord may incur or suffer as a result of Tenant's default
or in reletting the Leased Premises. Tenant further agrees to reimburse Landlord

subparagraph, whether caused by the negligence of Landlord or otherwise.

                (d) Landlord may pursue any remedy provided at law or in equity.

                (e) Landlord shall have no duty to relet the Premises, and the
failure of Landlord to do so shall not release or affect Tenant's liability for
Rentals and other charges due hereunder or for damages.

                (f) No re-entry or reletting of the Premises or any filing or
service of an unlawful detainer action or similar action shall be construed as
an election by Landlord to terminate Tenant's right to possession under this
Lease unless a written notice of such intention is given by Landlord to Tenant.
Notwithstanding any such reletting without termination, Landlord may at any time
thereafter elect to terminate this Lease and Tenant's right to possession
hereunder.

        28. TERMINATION OF OPTIONS: If there exist any options or special rights
which Landlord may have granted Tenant under this lease including, but not
limited to, options or rights regarding extensions of the lease term, expansion
of the Leased Premises, or acquisition of any other interest in the Leased
Premises or the Building, then all such options and rights are independent of
the leasehold estate hereby granted to Tenant by Landlord. Landlord and Tenant
agree and acknowledge that the negotiated consideration for any such options or
special rights is Tenant's entry into this Lease and that no portion of any sums
due and payable by Tenant to Landlord hereunder is attributable thereto. In
addition to, and not in lieu of, the above remedies of Landlord for Tenant's
default, any and all such options or special rights shall be automatically
terminated upon the occurrence of the following events:

                (a) Tenant shall have failed to pay when due any installment of

event of default described under Paragraph 26 above, whether or not such default
is cured by Tenant.

        29. WAIVER OF DEFAULT OR REMEDY: Failure of Landlord to declare a
default immediately upon its occurrence, or delay in taking any action in
connection with an event of default, shall not be waiver of the default.
Landlord shall have the right to declare the default at any time and take such
action as is lawful or authorized under this Lease. Pursuit of any one or more
of the remedies set forth in Paragraphs 27 or 28 above shall not preclude
pursuit of any one or more of the other remedies provided therein or elsewhere
in this Lease provided by law, nor shall pursuit of any remedy be a forfeiture
or waiver of any Rent or damages accruing to Landlord by reason of the violation
of any of the terms of this Lease. Failure by Landlord to enforce one or more of
its remedies upon an event of default shall not be construed as a waiver of the
default or of any other violation or breach of any of the terms contained in
this Lease.

        30. ATTORNEY'S FEES: In the event any litigation arises hereunder, it is
specifically stipulated that this Lease shall be interpreted and construed
according to the laws of the State in which the Leased Premises are located.

be entitled to recover, as a part of its judgment, reasonable attorney's fees.

of time or otherwise, surrender immediate possession to Landlord. If Landlord
agrees in writing that Tenant may hold over after the expiration or termination

shall be subject to termination by Landlord at any time upon not less than five
(5) days advance written notice, or by Tenant at any time upon not less than
thirty (30) days advance written notice. Further, all of the terms and
provisions of this Lease shall be applicable during the hold over period, except
that Tenant shall pay Landlord from time to time upon demand, as Base Rent for
the period of any hold over, an amount equal to one and one-half times (1-1/2)
the Base Rent in effect on the termination date, computed on a daily basis for
each day of the hold over period, plus all additional rental and other sums due
hereunder. If Tenant shall fail immediately to surrender possession of the
Leased Premises to Landlord upon termination of this Lease, by lapse of time or
otherwise, and Landlord has not agreed to such continued possession as above
provided, then, until Landlord can dispossess Tenant under the terms hereof or
otherwise. Tenant shall pay Landlord from time to time upon demand, as Base Rent
for the period of any such holdover, an amount equal to twice the Base Rent in
effect on the termination date, computed on a daily basis for each day of the
hold over period, plus all additional rental and other sums due hereunder. No
holding over by Tenant, whether with or without consent of Landlord, shall
operate to extend this Lease except as otherwise expressly agreed by the
parties. The preceding provisions of this Paragraph shall not be construed as
Landlord's consent for Tenant to hold over.

existing or hereafter to exist with respect to the Leased Premises. Landlord is

Purchaser, as its Landlord. Such attornment shall be effective without the
execution of any further instruments upon the Purchaser succeeding to the
interest of Landlord under this Lease. The respective rights and obligations of
Tenant and the Purchaser upon the attornment, to the extent of the then
remaining


                                      -8-

        8. Paragraph 6(b) of the Lease is hereby amended as follows:

                (a) As of October 1, 1995, the first sentence of Paragraph 6(b)

        In other words, commencing October 1, 1995 for any calendar year (or
        applicable portion thereof) Tenant shall be obligated to pay its pro

        prorated portion thereof).

                (b) In the event that during all or any portion of any calendar
        year the Building is not fully rented or fully occupied, Landlord may

        Expenses for such calendar year by determining the Common Area
        Maintenance Expenses that would have been incurred had the Building been
        ninety-five (95%) rented and occupied, and the amount so determined
        shall be deemed to have been the Common Area Maintenance Expenses for
        the applicable period.

                (c) Notwithstanding anything to the contrary contained in this

                such HVAC to be replaced and the monthly Base Rent payments
                under the Lease shall immediately be increased by an amount
                which would cause the full amount of all costs incurred by
                Landlord for the HVAC replacement, together with interest
                thereon at the rate of twelve percent (12%) per annum, to be
                repaid to Landlord over a five (5) year period. Nothing in the
                immediately preceding sentence shall in any way obviate Tenant's
                obligations under the Lease to maintain and repair the HVAC.

        10. Notwithstanding anything in the Lease to the contrary, construction
of leasehold improvements (the "Leasehold Improvements") in the Leased Premises

governed by Schedule 2 attached hereto and made a part hereof for all purposes.

        11. Tenant shall be responsible, at Tenant's sole cost and expense, for

as amended ("ADA") as such compliance relates to the Leased Premises. Tenant
shall be responsible, at Tenant's sole cost and expense, for compliance with any
and all present and future laws, rules and/or regulations regarding air quality

for compliance with the ADA as such compliance relates to the common areas of
the Building. Any expenses incurred by Landlord in connection with such
compliance shall be included in Common Area Maintenance Expenses.

entirety. Schedule 3 attached hereto is hereby made a part of the Lease and a
part hereof for all purposes.

        13. All capitalized terms used in this Amendment and not otherwise
defined herein, shall have the meaning ascribed to such terms in the Lease.

                                   SCHEDULE 2


                             LEASEHOLD IMPROVEMENTS


        1. Construction of Leasehold Improvements. Tenant shall retain its own
contractor to construct and install leasehold improvements in or respecting the
Leased Premises (the "Leasehold Improvements"), pursuant to a written
construction contract (the "Construction Contract") and subject to and in
accordance with this Schedule 2. Landlord and Tenant expressly understand and
agree (i) that Landlord shall have no responsibility or obligation for the
construction and installation of the Leasehold Improvements in and to or
respecting the Leased Premises, and (ii) Landlord shall have no responsibility
or obligation to pay for any of the Leasehold Improvements, except for the
Construction Allowance.

        2. Tenant's Contractor. Landlord shall have the right to approve
Tenant's selection of the contractor ("Tenant's Contractor") to construct the
Leasehold Improvements. Landlord shall have no obligation or duty to ensure
timely completion of, or supervise or manage in any way, the construction of the
Leasehold Improvements, and Landlord shall have no obligation to provide
builder's risk or other insurance on behalf of Tenant or Tenant's Contractor.
Landlord will cooperate with Tenant in the manner provided in subparagraphs (a)
and (b) below.

                (a) Access. Tenant shall be entitled to immediate possession of
        the Leased Premises for the purpose of constructing Tenant's Leasehold
        Improvements. Landlord shall take reasonable steps to provide any
        contractors and/or subcontractors engaged by Tenant and approved by
        Landlord with access to the common areas of the Building and to the
        Leased Premises as is reasonably necessary in order to allow Tenant to
        construct the Leasehold Improvements, subject to such requirements,
        rules and regulations as Landlord may reasonably impose from time to
        time.

                (b) Water and Electrical Power. Landlord will provide to Tenant
        and Tenant's Contractor water and electrical power to the Leased
        Premises 24 hours per day, 7 days per week during the period of
        construction of the Leasehold Improvements.

        3. Construction Allowance.

                (a) Landlord shall provide to Tenant an allowance (the
        "Construction Allowance") not to exceed $38,992.00 to be used by Tenant
        to construct and install the Leasehold Improvements in the Leased
        Premises upon the terms and conditions set forth in this Schedule 2.
        Landlord and Tenant agree that Landlord shall own the Leasehold
        Improvements as constructed by Tenant and Tenant shall have no right or
        interest in the Leasehold Improvements except as a lessee hereunder. The
        cost of the Leasehold Improvements shall include all costs of labor and
        materials for the physical improvements to the Leased Premises
        including, but not limited to, partitioning, doors, frames, hardware,
        millwork, finishes, mechanical work and electrical work, plus fees and
        overhead to Tenant's Contractor. Any portion of the Construction
        Allowance not used for construction of the Leasehold Improvements shall
        be forfeited by Tenant and Tenant shall not receive such unused portion
        of the Construction Allowance or any credit therefor.

                (b) Landlord shall disburse the Construction Allowance to Tenant
        to enable Tenant to make progress payments to pay costs of constructing
        and installing the Leasehold Improvements until the Construction
        Allowance has been fully exhausted; provided, that Landlord shall not be
        obligated to disburse funds for materials stored off-site, and provided
        further, that Landlord receives from Tenant and is reasonably satisfied
        with the form and content of (a) a request for payment, (b) a copy of a
        certificate signed by Tenant's architect certifying the percentage of
        completion of the Leasehold Improvements and approving payment of an
        amount at least equal to the amount set forth in Tenant's request for
        payment, (c) partial releases of liens and/or lien waivers from Tenant's
        Contractor and subcontractors requesting payment, and (d) a copy of the
        Construction Contract (collectively, the "Back-Up"). Landlord shall not
        be obligated to make any payment of the Construction Allowance at any
        time there is an


                                       1
<PAGE>   24

        unbonded lien outstanding against the Building or the Leased Premises or
        Tenant's interest therein by reason of work done, or claimed to have
        been done, or materials supplied, or claimed to have been supplied, to
        or for Tenant or the Leased Premises or if the conditions to advances of
        the Construction Allowance are not satisfied. Notwithstanding anything
        in this Paragraph 3 to the contrary Landlord shall not be required to
        make more than one (1) advance during any calendar month.

        4. Compliance of Leased Premises. Tenant shall be responsible for
complying with laws, ordinances and regulations applicable to the Leasehold
Improvements.

        5. Plans. Tenant's architect shall, at Tenant's expense, prepare all
plans and documents for the construction of the Leasehold Improvements, it being
understood and agreed, however, that all such plans and documents shall be
subject to Landlord's written approval. Tenant shall submit to Landlord final
working drawings for all Leasehold Improvements and such final working drawings
shall be subject to Landlord's prior approval. If there are any significant
changes by Tenant from the improvements set forth in the final working drawings
referred to above, each such change must receive the prior written approval of
Landlord. In the event of any change in the working drawings, Tenant shall, upon
completion of the Leasehold Improvements, furnish Landlord with an accurate
"as-built" plan of the portion of the Leasehold Improvements covered by such
changes as constructed. All design, construction and installation of the
Leasehold Improvements shall conform to the requirements of applicable building,
plumbing and electrical codes and the requirements of any authority having
jurisdiction with respect to such work. All plans and working drawings submitted
to Landlord for approval shall be deemed approved by Landlord on the fifteenth
(15th) business day after submission unless Landlord notifies Tenant to the
contrary.

        6. Construction Contractors. Landlord shall have the right to approve
the mechanical, electrical and structural contractors and engineers retained by
Tenant or Tenant's Contractor. The mechanical, electrical and structural
contractors and engineers retained by Tenant or Tenant's Contractor shall be
deemed approved by Landlord on the fifteenth (15th) business day after their
names are submitted to Landlord unless Landlord notifies Tenant to the contrary.
Any contractors and/or subcontractors engaged shall comply with all standards
and regulations established by Landlord in its reasonable discretion, provided
that same have been furnished to Tenant in advance by Landlord. Such contractors
and subcontractors shall coordinate their efforts to ensure timely completion of
all work. During construction of any improvements, all contractors and
subcontractors shall coordinate with Landlord the movement of equipment and
materials. All contractors and subcontractors shall ensure that the work be
conducted in such manner so as to maintain harmonious labor relations and not to
interfere with Landlord's operation of the Building and/or the use of the
Building by other tenants. Tenant shall provide Landlord with a copy of the
Construction Contract for Landlord's approval, prior to full execution thereof.
In addition, Tenant shall provide Landlord with all reasonable information that
Landlord may request concerning the construction and installation of the
Leasehold Improvements. Tenant shall maintain builder's risk and other insurance
during the construction of the Leasehold Improvements in conformity with
Tenant's obligations to maintain insurance as set forth in the Lease and shall
provide Landlord with certificates evidencing such builder's risk and other
insurance.

        7. Landlord's Approval. Any approval by Landlord or its architects of
any of Tenant's drawings, plans and specifications which are prepared in
connection with the construction of the Leasehold Improvements or any inspection
by Landlord of the Leasehold Improvements shall not in any way be construed or
operate to bind Landlord or to constitute a representation or warranty of
Landlord as to the adequacy of sufficiency of such drawings, plans and
specifications or the Leasehold Improvements to which they relate, for any use,
purpose or condition, but such approval shall merely be the consent of Landlord
as may be required hereunder in connection with the construction of Leasehold
Improvements.

                                   SCHEDULE 3


                                 RENEWAL OPTION


        Tenant shall have the right to renew and extend the term of this Lease
with respect to the Leased Premises then subject to this Lease for the Renewal
Term (herein so called) upon and subject to the following terms and conditions:

        1. Tenant may extend this Lease for one (1) Renewal Term of five (5)
years by Tenant's giving written notice thereof to Landlord no later than April
1, 2000. The Renewal Term shall commence immediately upon the expiration of the
original term of this Lease (as extended by the Third Amendment of Commercial
Lease Agreement), and upon exercise of the renewal option the date of expiration
of the term of this Lease shall automatically become the last day of the Renewal
Term.

        2. The exercise by Tenant of the renewal option set forth herein must be
made, if at all, by written notice executed by Tenant and delivered to Landlord
on or before the date set forth hereinabove. Once Tenant shall exercise the
renewal option, Tenant may not thereafter revoke such exercise. Tenant shall not
have the right to exercise the renewal option if Tenant is in default under this
Lease, either at the time Tenant gives notice of its election to renew, or
immediately prior to the commencement of the Renewal Term. Tenant's failure to
exercise timely the renewal option for any reason whatsoever shall conclusively
be deemed a waiver of such renewal option.

        3. Tenant shall take the Leased Premises "as is" for the Renewal Term
and Landlord shall have no obligation to make any improvements or alterations to
the Leased Premises.

        4. Base Rent for the Renewal Term shall be at the Fair Market Value Rate
(hereinafter defined) multiplied by the number of net rentable square feet of
floor space in the Leased Premises, provided, however, that in no event shall
the Base Rent for the Renewal Term be less than the Base Rent in effect
immediately prior to the expiration of the original term of this Lease (as
extended by the Third Amendment of Commercial Lease Agreement). For purposes
hereof the "Fair Market Value Rate" means the fair market rental rate per square
foot of net rentable square feet of floor space in the Leased Premises which
Landlord is charging for a comparable lease term at the appropriate time for
comparable tenants leasing space of comparable size similarly situated in the
Building.

        5. Except as set forth in this Schedule 3, the leasing of the Leased
Premises for the Renewal Term shall be upon the same terms and conditions as are
applicable for the original term of this Lease (as extended by the Third
Amendment of Commercial Lease Agreement), and shall be upon and subject to all
of the provisions of this Lease, including without limitation the obligation of
Tenant to pay the amounts set forth in Paragraph 4 above.

                    INTELLECTUAL PROPERTY SECURITY AGREEMENT


        This Intellectual Property Security Agreement (the "Agreement") is made
as of July 8, 1999, by and between Avanex Corporation ("Grantor"), and COMERICA
BANK-CALIFORNIA, ("Secured Party")

                                    RECITALS

        A. Secured Party has agreed to lend to Grantor, certain funds (the
"Loan") and Grantor desires to borrow such funds from Secured Party pursuant to
the terms of a REVOLVING CREDIT & SECURITY AGREEMENT, dated of even date
herewith, (the "Loan Documents"). All capitalized terms used herein without
definition shall have the meanings ascribed to them in the Loan Documents.

        B. In order to induce Secured Party to make the Loan, Grantor has agreed
to assign certain intangible property to Secured Party for purposes of securing
the obligations of Grantor to Secured Party.

        NOW, THEREFORE, THE PARTIES HERETO AGREE AS FOLLOWS:

        1. Grant of Security Interest. As collateral security for the prompt and
complete payment and performance of all of Grantor's present or future
indebtedness, obligations and liabilities to Secured Party, Grantor hereby
grants a security interest and mortgage to Secured Party, as security, in and to
Grantor's entire right, title and interest in, to and under the following (all
of which shall collectively be called the "Collateral"):

               (a) Any and all copyright rights, copyright applications,
copyright registrations and like protections in each work or authorship and
derivative work thereof, whether published or unpublished and whether or not the
same also constitutes a trade secret, now or hereafter existing, created,
acquired or held, including without limitation those set forth on Exhibit A
attached hereto (collectively, the "Copyrights");

               (b) Any and all trade secrets, and any and all intellectual
property rights in computer software and computer software products now or
hereafter existing, created, acquired or held;

               (c) Any and all design rights which may be available to Grantor
now or hereafter existing, created, acquired or held;

               (d) All patents, patent applications and like protections
including, without limitation, improvements, divisions, continuations, renewals,
reissues, extensions and continuations-in-part of the same, including without
limitation the patents and patent applications set forth on Exhibit B attached
hereto (collectively, the "Patents");

               (e) Any trademark and servicemark rights, whether registered or
not, applications to register and registrations of the same and like
protections, and the entire goodwill of the business of Grantor connected with
and symbolized by such trademarks, including without limitation those set forth
on Exhibit C attached hereto (collectively, the "Trademarks");

               (f) Any and all claims for damages by way of past, present and
future infringement of any of the rights included above, with the right, but not
the obligation, to sue for and collect such damages for said use or infringement
of the intellectual property rights identified above;

               (g) All licenses or other rights to use any of the Copyrights,
Patents or Trademarks, and all license fees and royalties arising from such use
to the extent permitted by such license or rights; and

               (h) All amendments, extensions, renewals and extensions of any of
the Copyrights, Trademarks or Patents; and



                                        1
<PAGE>   2

               (i) All proceeds and products of the foregoing, including without
limitation all payments under insurance or any indemnity or warranty payable in
respect of any of the foregoing.

Notwithstanding the foregoing, the security interest granted herein shall not
extend to and the term "Collateral" shall not include any property, rights or
licenses to the extent the granting of a security interest therein (i) would be
contrary to applicable law or (ii) is prohibited by or would constitute a
default under any agreement or document governing such property, rights or
licenses (but only to the extent such prohibition is enforceable under
applicable law including without limitation Section 9318 of the Code); provided
that immediately and automatically upon the ineffectiveness, lapse or
termination of any such prohibition or restriction, the Collateral shall include
such property, rights or licenses, and Borrower shall be deemed to have granted
a security interest in all such rights and interests as if such prohibition or
restriction has never been in effect.

        2. Authorization and Request. Grantor authorizes and requests that the
Register of Copyrights and the Commissioner of Patents and Trademarks record
this security agreement.

        3. Covenants and Warranties. Grantor represents, warrants, covenants and
agrees as follows:

               (a) Grantor is now the sole owner of the Collateral, except for
non-exclusive licenses granted by Grantor to its customers in the ordinary
course of business;

               (b) Performance of this Agreement does not conflict with or
result in a breach of any agreement to which Grantor is party or by which
Grantor is bound, except to the extent that certain intellectual property
agreements prohibit the assignment of the rights thereunder to a third party
without the licensor's or other party's consent and this Agreement constitutes
an assignment;

               (c) During the term of this Agreement, Grantor will not transfer
or otherwise encumber any interest in the Collateral, except for non-exclusive
licenses granted by Grantor in the ordinary course of business, or as set forth
in this Agreement or other Permitted Liens (as defined in the Loan Documents);

               (d) Each of the Patents is valid and enforceable, and no part of
the Collateral has been judged invalid or unenforceable, in whole or in part,
and no claim has been made that any part of the Collateral violates the rights
of any third party;

               (e) Grantor shall deliver to Secured Party within thirty (30)
days of the last day of each fiscal quarter, a report signed by Grantor, in form
reasonably acceptable to Secured Party, listing any applications or
registrations that Grantor has made or filed in respect of any patents,
copyrights or trademarks and the status of any outstanding applications or
registrations. Grantor shall promptly advise Secured Party of any material
change in the composition of the Collateral, including but not limited to any
subsequent ownership right of the Grantor in or to any Trademark, Patent or
Copyright not specified in this Agreement;

               (f) Grantor shall (i) protect, defend and maintain the validity
and enforceability of the Trademarks, Patents and Copyrights, (ii) use its best
efforts to detect infringements of the Trademarks, Patents and Copyrights and
promptly advise Secured Party in writing of material infringements detected and
(iii) not allow any Trademarks, Patents or Copyrights to be abandoned, forfeited
or dedicated to the public without the written consent of Secured Party, which
shall not be unreasonably withheld, unless Grantor determines that reasonable
business practices suggest that abandonment is appropriate;

               (g) Grantor shall register or cause to be registered (to the
extent not already registered) with the United States Patent and Trademark
Office or the United States Copyright Office, as applicable, those intellectual
property rights listed on Exhibits A, B and C hereto within thirty (30) days of
the date of this Agreement. Grantor shall register or cause to be registered
with the United States Patent and Trademark Office or the United States
Copyright Office, as applicable, those additional intellectual property rights
developed or acquired by Grantor from time to time in connection with any
product prior to the sale or licensing of such product to any third party
(including without limitation revisions or additions to the intellectual
property rights listed on such Exhibits A, B and C). Grantor shall, from time to
time, execute and file such other instruments, and take such further actions as



                                        2
<PAGE>   3

Secured Party may reasonably request from time to time to perfect or continue
the perfection of Secured Party's interest in the Collateral:.

               (h) This Agreement creates, and in the case of after acquired
Collateral, this Agreement will create at the time Grantor first has rights in
such after acquired Collateral, in favor of Secured Party a valid and perfected
first priority security interest in the Collateral in the United States securing
the payment and performance of the obligations evidenced by the Loan Documents
upon making the filings referred to in clause (i) below;

               (i) Except for, and upon, the filing with the United States
Patent and Trademark office with respect to the Patents and Trademarks and the
Register of Copyrights with respect to the Copyrights necessary to perfect the
security interests created hereunder, and, except as has been already made or
obtained, no authorization, approval or other action by, and no notice to or
filing with, any U.S. governmental authority or U.S. regulatory body is required
either (i) for the grant by Grantor of the security interest granted hereby or
for the execution, delivery or performance of this Agreement by Grantor in the
U.S. or (ii) for the perfection in the United States or the exercise by Secured
Party of its rights and remedies hereunder;

               (j) All information heretofore, herein or hereafter supplied to
Secured Party by or on behalf of Grantor with respect to the Collateral is
accurate and complete in all material respects.

               (k) Grantor shall not enter into any agreement that would
materially impair or conflict with Grantor's obligations hereunder without
Secured Party's prior written consent, which consent shall not be unreasonably
withheld. Grantor shall not permit the inclusion in any material contract to
which it becomes a party of any provisions that could or might in any way
prevent the creation of a security interest in Grantor's rights and interests in
any property included within the definition of the Collateral acquired under
such contracts, except that certain contracts may contain anti-assignment
provisions that could in effect prohibit the creation of a security interest in
such contracts if Grantor is required, in its commercially reasonable judgment
to accept such provisions; and

               (l) Upon any executive officer of Grantor obtaining knowledge
thereof, Grantor will promptly notify Secured Party in writing of any event that
materially adversely affects the value of any of the Collateral, the ability of
Grantor to dispose of any Collateral or the rights and remedies of Secured Party
in relation thereto, including the levy of any legal process against any of the
Collateral.

        4. Secured Party's Rights. Secured Party shall have the right, but not
the obligation, to take, at Grantor's sole expense, any actions that Grantor is
required under this Agreement to take but which Grantor fails to take, after
fifteen (15) days' notice to Grantor. Grantor shall reimburse and indemnify
Secured Party for all reasonable costs and expenses incurred in the reasonable
exercise of its rights under this section 4.

        5. Inspection Rights. Grantor hereby grants to Secured Party and its
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable written notice to Grantor, any of Grantor's plants
and facilities that manufacture, install or store products (or that have done so
during the prior six-month period) that are sold utilizing any of the
Collateral, and to inspect the products and quality control records relating
thereto upon reasonable notice to Grantor and as often as may be reasonably
requested. Notwithstanding any provision of this Agreement to the contrary,
except upon the occurrence and continuation of an Event of Default, Grantor
shall not be required to disclose, permit the inspection, examination, copying
or making extracts of, or discuss, any document, information or other matter
that (i) constitutes non-financial trade secrets or non-financial proprietary
information, or (ii) the disclosure of which to the Secured Party, or its
designated representative, is then prohibited by (a) law, or (b) an agreement
binding on the Grantor that was not entered into by the Grantor for the primary
purpose of concealing information from the Secured Party.

        6.     Further Assurances; Attorney in Fact.

               (a) On a continuing basis, Grantor will make, execute,
acknowledge and deliver, and file and record in the proper filing and recording
places in the United States, all such instruments, including, appropriate
financing and continuation statements and collateral agreements and filings with
the United States Patent and



                                        3
<PAGE>   4

Trademark Office and the Register of Copyrights, and take all such action as may
reasonably be deemed necessary or advisable, or as requested by Secured Party,
to perfect Secured Party's security interest in all Copyrights, Patents and
Trademarks and otherwise to carry out the intent and purposes of this Agreement,
or for assuring and confirming to Secured Party the grant or perfection of a
security interest in all Collateral.

               (b) Grantor hereby irrevocably appoints Secured Party as
Grantor's attorney-in-fact, with full authority in the place and stead of
Grantor and in the name of Grantor, from time to time in Secured Party's
discretion, to take any action and to execute any instrument which Secured Party
may deem necessary or advisable to accomplish the purposes of this Agreement,
including:

                      (i) To modify, in its sole discretion, this Agreement
without first obtaining Grantor's approval of or signature to such modification
by amending Exhibit A, Exhibit B and Exhibit C, hereof, as appropriate, to
include reference to any right, title or interest in any Copyrights, Patents or
Trademarks acquired by Grantor after the execution hereof or to delete any
reference to any right, title or interest in any Copyrights, Patents or
Trademarks in which Grantor no longer has or claims any right, title or
interest;

                      (ii) To file, in its sole discretion, one or more
financing or continuation statements and amendments thereto, relative to any of
the Collateral without the signature of Grantor where permitted by law; and

                      (iii) After the occurrence of an Event of Default, to

California Uniform Commercial Code, including without limitation the right to
require Grantor to assemble the Collateral and any tangible property in which

reasonably necessary to permit Secured Party to exercise its rights and remedies
upon the occurrence of an Event of Default. Grantor will pay any expenses
(including attorneys' fees) incurred by Secured Party in connection with the
exercise of any of Secured Party's rights hereunder, including without
limitation any expense incurred in disposing of the Collateral. All of Secured

Party as a result of or in any way arising out of, following or consequential to
transactions between Secured Party and Grantor, whether under this Agreement or
otherwise (including without limitation attorneys fees and expenses), except for
losses arising from or out of Secured Party's gross negligence or willful
misconduct.

        10. Course of Dealing. No course of dealing, nor any failure to
exercise, nor any delay in exercising any right, power or privilege hereunder
shall operate as a waiver thereof.

        11. Attorneys Fees. If any action relating to this Agreement is brought
by either party hereto against the other party, the prevailing party shall be
entitled to recover reasonable attorneys fees, costs and disbursements.

                               AVANEX CORPORATION
                          LICENSE AND SUPPLY AGREEMENT

        This License and Supply Agreement (the "Agreement") is made and entered
into by and between Avanex Corporation, a California corporation with principal
offices at 42501 Albrae Street, Fremont, California 94538 ("Avanex"), and
Concord Micro-Optics, Inc. a California corporation with principal offices at
_____________________________ ("CMI"). The parties hereby agree as follows:

        1. Scope. In order to avoid repetitive negotiations, this Agreement
shall apply to all purchase orders placed by Avanex and accepted by CMI (or the
JV Co., as defined below) during the Term (as defined below) for the Products
described in Exhibit A attached hereto ("Product(s)"), as such Exhibit may be
amended from time to time to add products upon the mutual agreement of the
parties. This Agreement shall apply to all current or future divisions,
subsidiaries, affiliates, locations and operations of Avanex, wherever located.
It is acknowledged and agreed by the parties that as soon as practicable after
the execution of this Agreement, CMI will establish and control a Sino-foreign
joint venture company in Tianjin, China (the "JV Co.") organized under the laws
of the People's Republic of China ("PRC") and that CMI shall, within ten (10)
days of the establishment of the JVCo, cause the JV Co. to execute, and its
board of directors to ratify, the Acknowledgment and Agreement, in the form set
out in Exhibit B attached hereto, pursuant to which the JV Co. shall become a
party hereto. CMI and the JV Co. shall be jointly and severally liable for all
obligations of CMI contained herein.

        2. Term. The term of this Agreement shall commence upon execution of
this Agreement by Avanex and CMI (the "Effective Date") and shall continue for
[*](the "Initial Term"). Subject to a maximum aggregate of [*]), this Agreement
shall be automatically renewed for additional [*] (the "Extended Term") unless
either party gives written notice of termination at least [*] before the end of
the Initial Term or any [*] thereof or unless sooner terminated in accordance
with the provisions hereof (collectively the "Extended Term"). "Term" shall mean
the Initial Term and the Extended Term, if applicable.

        3. Terms and Conditions.

                (a) This Agreement contains the exclusive terms and conditions
which apply to all purchases, notwithstanding any purchase order, acknowledgment
or other business forms transmitted by CMI, the JV Co. or Avanex. All CMI and JV
Co. acknowledgments and invoices must reference this Agreement and the
applicable Avanex purchase order.

                (b) This Agreement does not constitute a purchase order.
Purchases hereunder shall be made only by Avanex's purchase orders issued by
Avanex's purchasing department. Avanex shall be liable under this Agreement only
for those Products covered by such purchase orders. [*]

        4. Products and Prices.



                                        1

- ----------
* Certain information on this page has been omitted and filed separately with
the Commission. Confidential treatment has been requested with respect to the
omitted portions.
<PAGE>   2

                (a) The Products covered by this Agreement and the prices for
such Products are as specified in Exhibit A. Prices are set forth in United
States Dollars.

                (b) CMI represents that to the best of its knowledge this
Agreement does not violate provisions of the Robinson-Patman Act.

                (c) [*]

                (d) The prices set forth in Exhibit A are inclusive of any and
all applicable taxes including any PRC and U.S. federal, state and local VAT
sales, use and like taxes and any such applicable taxes shall be detailed on
CMI's invoice. If Avanex complies with the U.S. statutory resale tax certificate
requirements of states where appropriate, no sales, use or like taxes shall be
included in the price.

                (e) The parties agree that any new or modified Products will be
priced based upon assumed volumes and complexity factors employed in the pricing
model of that Product that most closely resembles the new or modified Products
to be priced.

        5. F.O.B. Point. Unless otherwise specifically provided on the face of
the purchase order, Products shall be delivered on an F.O.B. destination basis
to the Avanex's designated plant in Fremont, California, at which time title
shall pass to Avanex. CMI shall insure and ship such items at Avanex's expense.
Orders which are to be drop shipped to Avanex's customers will be designated on
the purchase order as F.O.B. CMI, at CMI's manufacturing facility. Avanex will
specify carrier, insurer and freight terms.

        6. Invoices.

                (a) Upon shipment of Products ordered, CMI will submit to Avanex
an invoice showing invoice number and date, remit to address, the purchase order
number, Avanex part number and revision, quantity of each Product, unit prices,
each applicable tax and extended totals.

                (b) Avanex shall pay each invoice by the later of:

                        (i) Payment Due Date which is defined as thirty (30)
days after the receipt of invoice, or

                        (ii) thirty (30) days after receipt of the shipment.

        7. Ordering and Delivery.

                (a) Avanex shall provide CMI with a non-binding rolling [*]
forecast on a [*] basis of the quantity of each Product desired. Actual
Avanex orders shall be submitted by telecopier or in writing on Avanex's
standard purchase order form and shall



                                        2

- ----------
* Certain information on this page has been omitted and filed separately with

<PAGE>   3

specify the purchase order number, Avanex part number for each Product, quantity
of Product desired, the locations to which the Product is to be delivered, and
the date or dates desired for delivery of the ordered Product to such locations.

                (b) CMI agrees to accept each order for the full quantity of
Product ordered. After receipt of an order from Avanex, CMI shall notify Avanex
within seventy-two (72) hours if CMI cannot meet the desired delivery date(s)
and will propose alternative delivery date(s). If, within seven (7) business
days after notification of any proposed alternative delivery date(s), Avanex
does not notify CMI of Avanex's rejection of CMI's alternative delivery date(s),
or otherwise reach agreement with CMI on the agreed delivery date, then the
order shall be considered confirmed with the alternative delivery date(s)
becoming the agreed delivery date. CMI's failure to so notify Avanex shall
constitute CMI's agreement to Avanex's desired delivery date(s), which will then
become the agreed delivery date. CMI shall send Avanex a formal written
acknowledgment of each Avanex purchase order within five (5) business days. All
delivery dates and the terms "deliver" and "delivery" as used herein, shall
refer to delivery to Avanex's designated plant in Fremont, California, or in the
instance of any order to be drop shipped to Avanex's customer, delivery by CMI
to the freight carrier specified in such order, or if no carrier is specified,
to the carrier selected by CMI.

                (c) Notwithstanding anything set forth above to the contrary,
all Avanex requested delivery dates providing the minimum number of business
days lead time specified in Exhibit A of this Agreement for a Product (the "Lead
Time") shall be the Agreed delivery date. The Lead Time set forth on Exhibit A
may be adjusted by CMI: (i) upon thirty (30) days written notice with respect to
increases in Lead Times; or immediately upon written notice to Avanex with
respect to decreases in Lead Times. CMI agrees to use its best efforts to
minimize the Lead Times set forth on Exhibit A.

                (d) CMI shall meet the agreed delivery dates and understands
that time is of the essence with respect to its performance of its obligations
hereunder. CMI agrees that its obligations to use its best efforts include an
obligation to diligently monitor its performance against its delivery
obligations hereunder and agrees that any failure to perform such monitoring
obligations shall constitute a material default of this Agreement.

                (e) CMI agrees to maintain safety stock of component parts for
the quantities of Products set forth on Exhibit C hereto as amended by Avanex
from time to time by written notice to CMI.

                (f) Certain long lead time components (the "Long Lead
Components") are set forth on Exhibit D. Avanex shall update Exhibit D from time
to time by written notice to CMI. CMI agrees to use Avanex's forecast of
Products volumes and its material planning system to calculate the quantities of
such Long Lead Components which should be ordered in advance of Avanex's
issuance of a purchase order for Products hereunder in order for CMI to meet the
Lead Times set forth on Exhibit A. CMI shall prepare a report setting forth the
quantities of such Long Lead Components which must be ordered, the quantities
already on order in advance of Avanex's issuance of purchase orders.

        8. Avanex Requested Changes.

                (a) Avanex may, at any time, make changes in writing to any of
the following:

                        (i) applicable drawings, designs or specifications,

                        (ii) method of shipment or packing, and



                                        3
<PAGE>   4

                        (iii) place of delivery.

If the change causes an increase in the cost or the time required by CMI for
performance of any purchase order issued under this Agreement and CMI so
notifies Avanex in writing, then if Avanex wishes such change to be made, an
equitable adjustment will be made in the price or delivery schedule or both and
the Agreement and/or any applicable purchase order will be modified accordingly
in writing. With respect to rework orders, the parties shall negotiate in good
faith to determine the price of such changes. Claims by CMI for adjustment due
to an Avanex change order must be made within fifteen (15) days from the date of
CMI's receipt of the change order; such period may be extended upon the written
approval of Avanex.

                (a) If Avanex decides to cancel any definitive purchase order,
Avanex must give CMI forty-five (45) days' notice before CMI's committed
delivery date. If the time period remaining between the then current date and
CMI's committed delivery date for a Product is less than forty-five (45) days,
Avanex must pay CMI [*] of the canceled amount.

                (b) If the time period remaining between the then current date
and CMI's committed delivery date for a Product is more than forty-five (45)
days, then Avanex may with respect to each purchase order and at no charge make
any changes to delivery dates and unit quantities for such Product.

        9. Over Shipments. Avanex will pay only for maximum quantities ordered,
unless Avanex has issued a change order authorizing an over shipment prior to
such delivery by CMI.

        10. Early Shipments and Late Shipments. For Products delivered five (5)
or more days before or seven (7) or more days after the agreed delivery date,
Avanex may:

                (a) Return such Products to CMI (or to the JV Co., as the case
may be) freight collect,

                (b) Accept such Products with payment based upon the agreed
delivery date and not the date of receipt by Avanex, or

                (c) In the event of late shipments, charge CMI (or the JV Co.,
as the case may be) a late delivery fee equal to [*] of the agreed delivery
amount for each full week of delay.

        11. Modifications to Agreed Delivery Dates. CMI shall at all times use
its best efforts to deliver the unit quantity of Products to be delivered to
Avanex on the agreed delivery date. If, after employing such best efforts, CMI
first determines that it will be unable to deliver the unit quantity of Products
to be delivered to Avanex on the Agreed delivery date, then CMI shall notify
Avanex within twenty-four hours of such determination, and the parties will
negotiate in good faith new agreed delivery date, predicated on CMI's continued
use of such best efforts, for such Product(s). Any partial deliveries resulting
from such re-scheduling shall be separately invoiced by CMI and paid for by
Avanex without regard to subsequent deliveries.

        12. [*]

packing materials or Styrofoam.

                (b) Shipments of Product having multiple date codes at the
intermediate container level must have the unit containers organized to afford
easy identification and separation, Therefore:

                        (i)     unit containers may not contain mixed date
                                codes;

                        (ii)    intermediate containers may not contain more
                                than two (2) date codes; and

                        (iii)   shipments may not contain more than five (5)
                                date codes.

                (c) Intermediate containers shall be marked with a label on the
end listing:

                        (i)     CMI's name, part number, part description;

                        (ii)    total quantity of Product in the container, date
                                code(s) by quantity; and

                        (iii)   Avanex's part number and purchase order number

                (d) The maximum acceptable weight for the shipping container is
45 pounds. Skids or pallets must be used with containers that are unsuitable for
manual handling.

        14. Acceptance and Quality.

                (a) Avanex may inspect the Products, materials and components
held by JV Co. for Avanex at JV Co.'s facilities during JV Co.'s regular

security and handling measures of the JV Co. while on JV Co.'s premises.



                                        5
<PAGE>   6

                (b) CMI covenants to Avanex that Products sold to Avanex will
meet or exceed Avanex's product qualification requirements. Subject to the
provisions of Section 14(f) below, CMI will provide the following types of
quality inspections in accordance with its own published manual and, when
applicable, Avanex provided specifications, drawings and other such
documentation:

                        (i)     incoming material inspections;

                        (ii)    in-process inspections;

                        (iii)   vendor control; and

                        (iv)    final inspection.

                (c) CMI may not make parts substitutions without the prior
written approval of Avanex. CMI shall direct all such requests for parts
substitutions to Avanex's Contract Administrator, as set forth below.

                (d) Avanex may inspect, and based upon the results of such
inspection, reject or accept Products delivered hereunder in a reasonable period
of time. Any Products rejected shall be returned to CMI (or JV Co.) upon
Avanex's receipt of a return materials authorization ("RMA") for such return.
CMI shall issue RMA numbers within two (2) business days. Avanex shall return
Products in the original shipping container, if possible; otherwise Avanex shall
use a similar shipping container and such container shall be marked with the RMA
number. CMI shall repair or replace such rejected Products within five (5)
business days. With respect to Products to be repaired or replaced, the date
determined in the prior sentence shall be deemed an Agreed Delivery Date for
purposes of this Agreement, subject to modification in accordance with Section
11 hereof.

                (e) Personnel designated by Avanex may freely communicate with
designated personnel of CMI (or JV Co.) with respect to technical assistance and
exchanges of information. Avanex's designated personnel shall, as reasonable,
provide technical assistance and answer questions for JV Co. personnel from time
to time, provided, however, that such communication shall not permit CMI to
deviate from any of its obligations under this Agreement.

        25. Transfer of Information. In connection with this Agreement, Avanex
shall provide CMI with information necessary to produce the Products. Such
information transfer shall take place in the manner set forth in Exhibit F
attached hereto. CMI acknowledges that all information to be transferred to it
by Avanex pursuant to this Section 25 is Proprietary and Confidential
Information (as defined below) of Avanex subject to the obligations of
Confidentiality in Section 26.

        26. Confidential Information.

                (a) CMI acknowledges that information which Avanex may disclose
to CMI (or JV Co.) in a tangible form marked "Confidential," "Proprietary" (or
with similar legend), or that is disclosed orally and confirmed in writing as
confidential within a reasonable time, comprises proprietary and confidential
information of Avanex ("Confidential Information"). In addition, Confidential
Information shall include all designs, engineering details, schematics,
drawings, and specifications developed by CMI (or JV Co.) with respect to the
Products. If Confidential Information is orally disclosed it shall be identified
as such at the time of disclosure and a confirmation of the confidential nature
of the information shall be sent to the CMI (or JV Co.) within thirty (30) days
after the disclosure.

                (b) CMI agrees not to use Confidential Information or disclose,
distribute or disseminate such Confidential Information to any third person
except as expressly permitted under this Agreement or as expressly agreed in
writing by Avanex. CMI agrees to restrict access to such Confidential
Information to those employees, contractors or consultants of CMI or JV Co. who
have agreed to be bound by and have duly executed a Confidentiality Undertaking
in the form set forth in Exhibit G. CMI shall not use such materials at a
location other than at the JV Co.'s registered address in Tianjin, China without
Avanex's prior written consent. CMI agrees to establish adequate internal
safeguards and otherwise use reasonable care in restricting the use and
dissemination of any Confidential Information in order to protect against its
unauthorized use or disclosure to any third party. CMI shall exercise the same
degree of care to prevent unauthorized use or disclosure of the Confidential
Information to others as it takes to preserve and safeguard its own confidential
information, but in any event, no less than a reasonable degree of care.

                (c) CMI (or JV Co.) shall be permitted to disclose to any
government, regulatory authority or court, any Confidential Information if CMI
(or JV Co.) is required by law or judicial decree to do so for the express
purposes of obtaining their approval to make Licensed Products in the PRC. Such
disclosure shall not constitute a breach of this Agreement provided that CMI
promptly notifies Avanex when such obligation of disclosure arises to enable CMI
to seek an appropriate protective order and to make known to the said
government, regulatory authority or court the proprietary nature of the
Confidential Information to be disclosed and to make any applicable claim of
confidentiality prior to the disclosure being made and provided CMI has first
informed Avanex of any requirement that exists in Chinese laws, regulations or
judicial decrees for that government, regulatory authority or court to make
further disclosures of the information to any third party.

                (d) CMI shall be relieved of this obligation of confidentiality
to the extent any Avanex information:

                        (i) was in the public domain at the time it was
disclosed or has become in the public domain through no fault of CMI;

                        (ii) CMI can prove was known to CMI, without
restriction, at the time of disclosure as shown by the files of the CMI in
existence at the time of disclosure;

                        (iii) is disclosed by CMI with the prior written
approval of Avanex;

                        (iv) CMI can prove was independently developed by CMI
without any use of the Confidential Information and by employees or other agents
of (or independent contractors hired by) CMI who have not had access to any
Confidential Information; or

                        (v) becomes known to CMI, without restriction, from a
source other than Avanex without breach of this Agreement by CMI and otherwise
not in violation of Avanex's rights.

                (e) CMI acknowledges that breach of the confidentiality
obligation would cause irreparable harm to Avanex, the extent of which would be
difficult to ascertain. Accordingly, CMI agrees that Avanex may seek immediate
injunctive relief in the event of breach of the confidentiality obligation by
CMI or JV Co.

                (f) Within seventy-five (75) business days after termination of
this Agreement, CMI shall promptly return all tangible materials containing such
Confidential Information to Avanex. Concurrently with the return of such
materials, CMI agrees to confirm in writing that all materials containing
Confidential Information have been returned to Avanex by CMI.

        27 License, Intellectual Property Rights

                (a) For so long as this license remains in effect under PRC law,
Avanex hereby grants to CMI and JV Co. (i) a [*] restrictive, nontransferable,
license with no right to sublicense under which CMI may (A) make Licensed
Products (as set forth on Exhibit H) in the PRC (excluding the Hong Kong SAR,
Macau, and Taiwan) and in the United States and use and sell Licensed Products
worldwide, and (ii) use the Licensed Information (as set forth on Exhibit H) in
China and the United States. This license shall be exclusive with respect to the
manufacture of Licensed Products in the PRC (excluding the Hong Kong SAR, Macau,

other party information related to any revision or improvement of Licensed
Products or Licensed Information.

                (b) Notwithstanding the foregoing, Avanex retains for itself all
proprietary and intellectual property rights including all patent rights in and
to all designs, engineering details, schematics, drawings, specifications and
other similar data and Confidential Information which:

                        (i) pertain to the Products; and are

property rights, including all patent rights, in and to such designs,
engineering details, schematics, drawings, specifications and other similar data
and Confidential Information. Avanex shall have the sole right to file any
patent applications thereon. CMI agrees to cooperate with Avanex and take all
reasonable additional actions and execute such agreements, instruments, and
documents as may be necessary or desirable to perfect Avanex's ownership
interests in accordance with the intent of this Section 27(b), including, but
not limited to, the execution of necessary and appropriate instruments of
assignment.

                (c) Any such information and materials which Avanex may furnish
to CMI (or JVCo) shall be in CMI's (or JV Co.'s) possession pursuant only to a
restrictive, nontransferable, nonexclusive license with no right to sublicense
under which CMI may use such information and materials solely for the purposes
of manufacturing, operating, servicing and repairing the Products for Avanex's
purposes pursuant to this Agreement. Within seventy-five (75) business days
after termination of this Agreement, CMI shall promptly return all tangible
materials containing such Confidential Information to Avanex. Concurrently with
the return of such materials, CMI agrees to confirm in writing that all
materials containing Confidential Information have been returned to Avanex by
CMI.

                (d) CMI shall inform Avanex in writing immediately upon becoming
aware of any use, suspected use, of the Licensed Information, or any party of
it, by any other party. In the event of any actual, any threatened or potential
litigation against Avanex alleging infringement of a third party's patent or any
other rights of such third party arising from the use of the Licensed
Information, CMI shall give immediate written notice to Avanex. Avanex shall
bear all legal and economic responsibilities for defending or otherwise dealing
with such actual or threatened litigation and CMI shall in a timely manner
provide Avanex with all assistance as may be reasonably requested by Avanex from
time to time. CMI agrees not to be involved in any discussions with any third
party relating to nor to take any steps relating to or to compromise any
litigation or threatened or potential litigation relating to the Licensed
Information, without the prior written consent of Avanex.

        28. Documentation Reproduction

                Subject to CMI's strict compliance with Sections 26 and 27 of
this Agreement, CMI may reproduce documentation, including Confidential
Information, in the performance of its obligations under this Agreement.

        29. Avanex-unique Components. Except in accordance with Section 27, CMI
will not ship any Product that is developed by, in conjunction with, or in
accordance with specifications from Avanex ("Avanex-unique Components"), to any
third party without the express, prior written consent of Avanex.

        30. Inventions.

                (a) All discoveries, improvements and inventions, whether or not
patentable, conceived or first reduced to practice, as those terms are used
before the U.S. Patent and Trademark Office, in the performance of this
Agreement by Avanex personnel shall be the sole and exclusive property of Avanex
and Avanex shall retain any and all rights to file any patent applications
thereon.

                (b) Subject to the provisions of Section 27(b) hereof, all

<PAGE>   11

                (c) Subject to the provisions of Section 27(b) hereof, all
discoveries, improvements and inventions conceived or first reduced to practice,
as those terms are used before the U.S. Patent and Trademark Office, whether or
not patentable, in the performance of this Agreement jointly by CMI personnel
and Avanex personnel (the "Joint Inventions"), shall be the property jointly of
CMI and Avanex, each party having [*] interest therein. Each party shall be
entitled to use, exploit, transfer, and grant licenses with respect to its
interest in Joint Inventions without notice or accounting to the other party.

        31. CMI's Process Changes. CMI agrees that it will not invoke any
changes in process, design or method of manufacturing that might affect form,
fit or function of the Products, including without limitation, changes in
performance, maintenance procedures, interchangeability, interconnectability,
reliability or manufacture compatibility of Products during the term of this
Agreement without Avanex's prior written consent. CMI further agrees that any
contemplated changes in process or method of manufacturing will be submitted to
Avanex in writing, (the original notification to be provided to the
Administrator and copies to Avanex personnel as may be required), in sufficient
time to enable Avanex a reasonable opportunity in which to evaluate such
changes. If said design change, in Avanex's opinion, necessitates evaluation by
Avanex of compatibility with Avanex's systems, CMI, upon request from Avanex,
will provide Avanex prototype units of Product for evaluation. Such design
change, once approved by Avanex, shall cause the revision level of the Product
to be rolled. CMI WILL NOT IMPLEMENT SUCH CHANGES WITHOUT THE PRIOR WRITTEN
CONSENT OF AVANEX.

        32. Discontinuance or Reduction of Production of a Product. CMI may
reduce or discontinue its production of a Product upon [*] prior written notice
to Avanex, so long as CMI does not offer such Product to any other of its
customers after it stops offering such Product to Avanex. Within sixty (60) days
after receipt by Avanex of written notice of such discontinuance ("Notice
Date"), Avanex may place and CMI shall accept all orders unless otherwise
precluded by any law, regulation, court judgment, order or permit, for delivery
over a [*] period following Notice Date with respect to any Product adversely
affected by such Product discontinuance. As a material inducement to entering
into this Agreement, CMI represents to Avanex that after diligent inquiry CMI is
aware of no Product or process involved in the production of any Product which
violates any law, regulation, judgment, order or permit.

        33. Safety Standards and Legal Compliance.

                (a) CMI will use its best efforts to provide information,
participate in inspections and perform all other actions reasonably requested by
Avanex to receive and/or maintain safety certifications by governmental
agencies, to the extent required or applicable.

                (b) CMI agrees to notify Avanex of any post-sale warnings,
retrofits or recalls which CMI implements with respect to any suppliers,
materials, and processes that are used by or for, or included in the Product(s).

                (c) CMI will promptly notify Avanex with respect to any matter
to which CMI receives or develops knowledge with respect to the safe and
reliable operation of the Product(s).

        34. Insurance. During the Term of this Agreement, CMI, at its sole cost
and expense, shall carry and maintain insurance adequate to cover its
manufacturing operations, product liability (naming Avanex as loss payee) and
its other obligations under this Agreement. CMI shall provide Avanex with a
Certificate of Insurance stating that such insurance policies are in full force
and effect. CMI shall require its insurer(s) to give Avanex thirty (30) days
written notice before the policy or policies are canceled or materially altered.

all Products delivered: (i) are new, unused, will be free from defects in
workmanship and manufacture; and (ii) will conform to the product and test
specifications incorporated by reference in Exhibit D and the Bellcore
standards, as applicable. CMI shall assign to Avanex any warranties with respect

CMI (or JV Co.) upon Avanex's receipt of a RMA for such return. CMI shall issue
RMA numbers within two (2) business days. Avanex shall return Products in the
original shipping container, if possible, otherwise Avanex shall use a similar
shipping container and such container shall be marked with the RMA number. CMI
shall repair or replace such rejected Products within five (5) business days.
With respect to Products to be repaired or replaced, the date determined in the
prior sentence shall be deemed an Agreed Delivery Date for purposes of this
Agreement, subject to modification in accordance with Section 11 hereof.

                (c) CMI shall not unreasonably withhold its approval of Avanex's
offer to correct itself, or to reimburse a third party to correct, the defective
or non-conforming Products and charge CMI with the cost of such correction.

                (d) Any repaired or replaced Products shall be subject to the
warranty set forth above. Out of warranty service shall be provided at CMI's
standard terms, conditions, and rates.

                (e) Subject to Avanex's rights with respect to Section 35(c) and
Section 36 hereof such repair or replacement shall be Avanex's exclusive remedy
and CMI's sole liability for any breach of the warranty set forth in this
Section.

        36. Indemnification and Hold Harmless. Subject to the limitations
provided in Section 39 of this Agreement, in connection with the transactions
contemplated by this Agreement CMI agrees to indemnify and hold Avanex harmless
from and against any claims, actions, losses, damages, costs and expenses
(including without limitation, reasonable attorneys' fees) arising from any of
the following:

                (a) breach or violation of any import or export laws of China or
the United States;

                (b) breach of any representation or warranty made by CMI in this
Agreement;

                (c) claim brought by any third party that CMI's (or the JV

Licensed Technology, violates any intellectual property rights of such party or
another third party; or

                (d) claim brought by any third party against Avanex for any
loss, damage, cost, expense or liability arising from defects in the Products

                (a) Avanex may, at any time prior to delivery, by written
notice, cancel this Agreement in whole or in part, or any purchase order issued

Delivery Date as such date may be modified under Section 11 hereof;

                        (ii) other than as provided in the previous clause,

                (b) If this Agreement or any purchase order under this Agreement
is canceled for CMI's default, Avanex may, in addition to all legal and
equitable remedies that may be available to Avanex, procure upon such terms and

substantially similar to those canceled. CMI will then be liable to Avanex for
any excess costs occasioned thereby.

                (c) If all or a portion of this Agreement or any purchase order
is canceled for CMI's default, Avanex may, in addition to all other remedies
that may be available to Avanex, require CMI to transfer title and to deliver to
Avanex, in the manner and to the extent directed by Avanex, provided that Avanex
pays for such property pursuant to Section 37(e), below:

                        (i) any completed items not yet delivered; and/or

                        (ii) any partially completed items and materials that
CMI (or JV Co.) has produced or acquired for the performance of the terminated
portion.

                (d) CMI will, upon direction of Avanex, protect and preserve the
property listed in this Section that is in the possession of CMI or JV Co.
Nothing in this Section 37 is intended to excuse CMI from proceeding with any
uncanceled portion of this Agreement or purchase order(s) under this Agreement.

                (e) Avanex will pay CMI the following amounts for property for
which title has been transferred and delivery completed under Section 37(c),
and/or for any services performed under Section 37(d), above:

services rendered in accordance with this Agreement;

                        (ii) the actual costs incurred by CMI which are properly
allocable under recognized commercial accounting practices to the terminated
portion of this Agreement, plus a fair and reasonable profit on such costs (as
reasonably agreed to by the parties) with respect to partially completed
Products and materials that CMI has produced or acquired for the performance of
the terminated portion of this Agreement. With respect to work in progress, if
it



                                       13
<PAGE>   14

appears that CMI would have sustained a loss on the order, no profit will be
allowed, and an adjustment will be made reducing the amount of the settlement to
reflect the indicated rate of loss; or

                        (iii) the reasonable costs incurred by CMI in protecting
property in which Avanex has or may acquire an interest under this Section 37.

                (f) Payments made under this Section 37 may not exceed the

excluded from amounts otherwise payable to CMI under this Section 37.

                (g) Both parties agree to negotiate in good faith the settlement
of any dispute that may arise under this Agreement. Pending settlement of any
dispute, CMI agrees to continue to fabricate and deliver Products under the
terms of this Agreement as directed by Avanex.

                (a) At any time for convenience, Avanex may terminate work under
this Agreement in whole or in part, by [*] written notice to CMI specifying the
extent to which performance of work is terminated and the time at which such

orders, settle all claims thereunder after obtaining Avanex's approval, protect
all property in which Avanex has or may acquire an interest, and transfer title
and make delivery to Avanex of all articles, materials, work in process, and
other things held or acquired by CMI in connection with the terminated portion
of this Agreement. CMI will proceed promptly to comply with Avanex's
instructions respecting each of the foregoing without awaiting settlement or
payment of its termination claim. Within thirty (30) days after such
termination, CMI may submit to Avanex its written claim for termination charges,
in the form and with the certifications prescribed by Avanex. Failure to submit
such a claim within thirty days will constitute an unconditional and absolute
waiver of all claims and a release of all Avanex's liability arising out of the
termination. The parties may agree upon the amount to be paid CMI for such
termination. If they fail to agree, Avanex will pay CMI the following amounts:

                        (i) the contract price for any completed Products or
services rendered in accordance with this Agreement;

                        (ii) the actual costs incurred by CMI which are properly
allocable under recognized commercial accounting practices to the terminated
portion of this Agreement, plus a fair and reasonable profit on such costs (as
reasonably agreed to by the parties) with respect to partially completed
Products and materials that CMI has produced or acquired for the performance of
the terminated portion of this Agreement. With respect to work in progress, if
it appears that CMI would have sustained a loss on the order, no profit will be
allowed, and an adjustment will be made reducing the amount of the settlement to
reflect the indicated rate of loss; or

                        (iii) the reasonable costs incurred by CMI in making
settlement and in protecting property in which Avanex has or may acquire an
interest.

                (b) Payments made under this Section 38 may not exceed the
aggregate price specified in this Agreement or purchase order(s) under this
Agreement less payments otherwise

made or to be made. Any amounts payable for property lost, damaged, stolen or
destroyed prior to delivery to Avanex will be excluded from amounts otherwise
payable to CMI under this Section 38.

                (c) Cancellation by Avanex under this Section 38 of any purchase
order shall not excuse CMI's performance with respect to any other Agreement or
Purchase order.

        39. LIMITATION OF LIABILITY. IN NO EVENT WILL EITHER AVANEX OR CMI OR JV
CO. BE LIABLE FOR ANY SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING OUT
OF THIS AGREEMENT, WHETHER UNDER THEORY OF CONTRACT, TORT (INCLUDING
NEGLIGENCE), PRODUCT LIABILITY OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES AND EVEN IF SUCH DAMAGES COULD HAVE BEEN REASONABLY FORESEEN.
NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS AGREEMENT IS MEANT TO ALTER THE
RIGHTS OR REMEDIES OF EITHER PARTY AGAINST THE OTHER PARTY IN ANY ACTION IN LAW
OR EQUITY BROUGHT BY A THIRD PARTY WITH REGARD TO ANY CLAIM MADE BY SUCH THIRD
PARTY.

        40. Force Majeure. Neither party shall be liable for any delay or
failure in performance hereunder caused by acts of God or other causes beyond
the parties' control and without fault or negligence. In the event CMI fails to
deliver Product due to such causes, Avanex may suspend this Agreement in whole
or in part for the duration of the delaying cause, and at Avanex's option, buy
the Products elsewhere and deduct from any purchase order to CMI the quantity so
purchased. CMI shall resume performance under this Agreement immediately after
the delaying cause ceases and, at Avanex's option, extend the Initial Term
and/or Term for a period equivalent to the length of time the excused delay
endured.

        41. Equal Opportunity. The "Equal Opportunity Clause" set forth in 41
C.F.R. section 60-1.4(a), the clause labeled "Affirmative Action of Disabled
Veterans and Veterans of the Vietnam Era" set forth in 41 C.F.R. section
60-250.4 and the clause labeled "Affirmative Action for Handicapped Workers" set
forth in 41 C.F.R. section 60-741.4 are hereby incorporated by reference and all
references in such clauses to "the contractor" shall be deemed to be references
to CMI.

        42. Government Contracts. If any purchase order under this Agreement is
issued for any purpose that is either directly or indirectly connected with the
performance of a prime contract with the U.S. government or a subcontract
thereunder, the terms that the Federal Acquisition Regulations or other
appropriate regulations required to be inserted in contracts or subcontracts,
except for those terms pertaining to cost and pricing data and cost accounting
standards, will be deemed to apply to any purchase order under this Agreement.
CMI will promptly notify Avanex if CMI becomes, or with the passage of time will
become, ineligible to perform contracts or subcontracts under U.S. Federal
Acquisition Regulations. Avanex shall use its best efforts to notify CMI of any
provision that is so passed on.

        43. Survival. Notwithstanding the termination or expiration of the
Initial Term of this Agreement or any Extended Term thereof, it is acknowledged
and agreed that those rights and obligations which by their nature are intended
to survive such expiration or earlier termination shall survive including,
without limiting the foregoing, following Sections: 26, 27(b) and (c), 28, 29,
30, 35, 39, 44, 45, 47 and 48, for a period of [*]. All obligations to return
information and materials shall survive the termination of this Agreement.

        44. Relationship of Parties.

any obligation or responsibility, express or implied, on behalf of the other
party or in the other party's name.

                (b) Nothing stated in this Agreement shall be construed as

master and servant, or principal and agent.

        45. Publicity. Neither Avanex or CMI shall publicize or disclose the

        46. Administration.

                (a) Avanex and CMI shall each assign an individual to administer
this Agreement throughout this term:

                      Avanex's Administrator shall be:

                             Mr. Jessy Chao
                             Avanex Corporation
                             42501 Albrae Street
                             Fremont, California 94538
                             (510) 360-0693

                      CMI's Administrator shall be:

                             --------------------------
                             --------------------------
                             --------------------------


                (b) Each party shall inform the Administrator of the other in
writing of a change of Administrator or such Administrator's address or
telephone number.

                (c) Any notice required or permitted to be given under this
Agreement shall be given in writing and shall be addressed to Avanex or CMI, as

be given in writing and: (i) by airmail, postage prepaid, certified mail, return
receipt requested; (ii) transmitted by facsimile with a confirming copy
immediately mailed thereafter; or (iii) delivered by a messenger or overnight
delivery service.

        47. General. This Agreement and all of its referenced Exhibits, which
are incorporated herein by reference as if set forth in full, together with all
purchase orders, but not the preprinted terms and conditions thereof, constitute
the entire agreement between the parties with respect to the subject matter
hereof and supersede all prior proposals, negotiations and communications, oral
or written, between the parties with respect to the subject matter hereof. No
deviation from these provisions shall be binding unless in writing and signed by
an authorized representative of the party to be charged.

                Except as specifically set forth herein, all rights and remedies
conferred under this Agreement or by any other instrument or law shall be
cumulative and may be exercised singularly or concurrently. Failure by either
party to enforce any provision shall not be deemed a waiver of future
enforcement of that or any other provision. In the event that any portion of
this



                                       16
<PAGE>   17

Agreement shall be held to be unenforceable, the remaining portions of this
Agreement shall remain in full force and effect and the parties shall negotiate
substitute provisions for those provisions held to be unenforceable that most
nearly effect the parties intent in entering into this Agreement. In the event
any provisions of this Agreement shall be held unenforceable against the JV Co.
under PRC law, CMI shall nevertheless be obligated to perform such obligation
unless the same shall be unenforceable under California law.

        48. Governing Law and Dispute Resolution. This Agreement is entered into
at Fremont, California and shall be governed by and construed in accordance with
the laws of the State of California, USA, except that body of law of California
law concerning conflicts of law. Any dispute, controversy or claim arising out
of or relating to this Agreement shall be finally and exclusively resolved by
submission to a single arbitrator in San Francisco, California in accordance
with the commercial arbitration rules of the American Arbitration Association.
The prevailing party shall be entitled to reasonable attorneys' fees and costs.
The arbitrator shall set a limited time period and establish procedures designed
to reduce the cost and time for discovery while allowing the parties an
opportunity, adequate in the sole judgment of the arbitrator, to discover
relevant information from the opposing parties about the subject matter of the
dispute. The arbitrator shall rule on motions to compel or limit discovery and
shall have the authority to impose sanctions, including attorneys' fees and
costs, to the same extent as a court of competent law or equity, should the
arbitrator determine that the discovery was refused or objected to without
substantial justification. The arbitrator shall have the authority to grant any
equitable and legal remedies that would be available in any judicial proceeding
instituted under California substantive law to resolve a dispute. Any award
issued by the arbitrator shall be final and binding on the parties and
enforceable against them. Any award issued against the JV Co. shall be
enforceable by any competent court having jurisdiction over the JV Co. in
accordance with the terms of the NEW YORK (UN) CONVENTION FOR THE RECOGNITION,
AND ENFORCEMENT OF FOREIGN ARBITRAL AWARDS.

        49. Assignments.

                (a) The rights, duties and obligations of CMI (or JV Co.) under
this Agreement may not be assigned in whole or in part by operation of law or
otherwise without the prior express written consent of Avanex, and any attempted
assignment of any rights, duties or obligations hereunder without such consent
shall be null and void. This Agreement shall be binding on the parties and their
respective successors and permitted assigns.

                (b) Avanex shall not assign its rights duties and obligations
under this Agreement without the prior written approval of CMI, which approval
CMI shall not unreasonably withhold, provided, however, that Avanex may assign
this Agreement without the prior written approval of CMI to a person or entity
into which Avanex has merged or which has otherwise succeeded to all or
substantially all of its business and assets, and which has assumed in writing
or by operation of law its obligations under this Agreement.

        50. Exhibits. The following is the list of Exhibits which are attached
hereto and hereby incorporated into this Agreement by reference:

                      INTERNATIONAL DISTRIBUTOR AGREEMENT

This International Distributor Agreement (the "Agreement") is made and entered
into this ___ day of November, 1999, by and between Avanex Corporation, a
corporation duly organized and existing under the laws of California, having its
principal place of business at 40919 Encyclopedia Circle, Fremont, California
94538 (hereinafter referred to as "Manufacturer") and Hakuto Co., Ltd., a
corporation duly organized and existing under the laws of Japan, having its
principal place of business at 1-13, Shinjuku 1-chome, Shinjuku-ku, Tokyo
160-8910, Japan (hereinafter referred to as "Hakuto" or "Distributor"),

WITNESSETH:

WHEREAS, Manufacturer is engaged in the business of the manufacture of various
photonic processors including the Products hereinafter defined; and

WHEREAS, Hakuto is engaged in the business of the sale and marketing of
merchandise throughout the world, including products similar or related to the
Products of Manufacturer; and

WHEREAS, Hakuto is desirous of being appointed distributor of the Products in
the Territory hereinafter defined.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein
contained, Manufacturer and Hakuto do hereby agree the terms and conditions set
forth below:


1.  Distributorship, Products and Territory

1.01 Distributorship. Manufacturer hereby grants to Hakuto during the term of
this Agreement the non-exclusive right to sell the Products in the Territory all
in accordance with the terms and conditions herein set forth. Distributor shall
pursue aggressive sales policies and procedures to realize the maximum sales
potential for the Products in the Territory. Manufacturer reserves the right to
market its products directly to the House Accounts set forth on Exhibit A.

1.02 Products. The term Products as used herein shall refer to the equipment set
forth on Exhibit B attached hereto and made a part hereof, as well as all
accessories, attachments, spare parts and renewal parts therefor. Manufacturer
shall have the right to modify, alter, improve, change or discontinue any or all
of the Products covered by this Agreement but only upon [*] prior written notice
to Hakuto. In the event Manufacturer manufactures any new or additional products
similar to or related to the Products hereunder, said products, at the option of
Hakuto, shall be added to the Products covered by this Agreement.

1.03 Territory. Territory shall have the meaning set forth in Exhibit C.

1.04 Conflict of Interest. Distributor warrants to Manufacturer that it does not
currently represent or promote any lines or products that compete with the
Products. During the term of this Agreement, Distributor shall not, without
Manufacturer's prior written consent, represent, promote or otherwise try to
sell within the Territory any lines or products that, in Manufacturer's
judgment, compete with the Products covered by this Agreement.


2.  Orders and Shipment

2.01 Order and Acceptance. Before accepting order from its customers, Hakuto
shall place written order inquiry for the Products with Manufacturer on Hakuto's
standard order inquiry form setting forth the quantity of Products, the
specifications therefor, and the desired delivery date. Manufacturer shall use
its reasonable best efforts to notify Distributor of the acceptance or rejection
of an order inquiry and of the assigned delivery date for accepted orders within
five (5) days after receipt of the order inquiry. Upon acceptance of the order
inquiry by the Manufacturer, Hakuto shall place written orders for the Products
with Manufacturer on Hakuto's standard purchase order form setting forth the
quantity of Products, the specifications therefor, and the desired delivery date
as agreed by Manufacturer. To facilitate Manufacturer's production scheduling,
Distributor shall submit purchase orders to Manufacturer at least sixty (60)
days prior to the first day of the requested month of delivery. No order shall
be binding upon Manufacturer until accepted by Manufacturer in writing, and
Manufacturer shall have no liability to Distributor with respect to purchase
orders that are not accepted. No partial shipment of an order shall constitute
the acceptance of the entire order, absent the written acceptance of such entire
order. Manufacturer shall use its reasonable best efforts to deliver Products at
the times specified

the Commission. Confidential treatment has been requested with respect to the
omitted portions.
<PAGE>   2

either in its quotation or in its written acceptance of Distributor's purchase
orders. The Products sold to Hakuto by Manufacturer shall be shipped F.O.B. (as
defined in Section 2319 of the California Uniform Commercial Code)
Manufacturer's factory at Fremont, CA to the destination in the Territory
designated by Hakuto in the purchase order, unless otherwise agreed by the
parties. Hakuto will supply a [*] rolling forecast throughout the agreement.


2.02 Reservation of Title. Title to and all risks of loss or damage of the
Products shipped to Hakuto from Manufacturer shall be subject to full payment of
the Purchase Price therefor. Until such full payment, the Product shall remain
the property of Manufacturer. For all Products to which Manufacturer retains
title, Distributor shall (i) carry full insurance on the Products throughout the
time they are in Distributor's possession and (ii) segregate those Products from
other products in Distributor's inventory.

2.03 Terms of Purchase Orders. Distributor's purchase orders submitted to
Manufacturer from time to time with respect to Products to be purchased
hereunder shall be governed by the terms of this Agreement, and nothing
contained in any such purchase order shall in any way modify such terms of
purchase or add any additional terms or conditions.

2.04 Import and Export Requirements. Distributor shall, at its own expense, pay
all import and export licenses and permits, pay customs charges and duty fees,
and take all other actions required to accomplish the export and import of the
Products purchased by Distributor. Distributor understands that Manufacturer is

6. Warranty to Distributor's Customers

6.01 Distributor shall pass on to its customers Manufacturer's standard limited
warranty for the Products, including the limitations set forth in 6.02 and 6.03
below. Manufacturer warranty shall state that the Products shall be free from
defects in design, materials and workmanship for a period of twelve (12) months
after the date of customer's acceptance. Manufacturer shall replace free of
charge all Products or parts found to be defective during said period. Hakuto

transportation charges for the return of defective Products or parts thereof,
and all transportation charges for the replacement Products or parts thereof.
Manufacturer shall supply Hakuto free of charge replacement parts necessary for
the after-sale warranty servicing performed by Hakuto and Manufacturer shall
provide to Hakuto for replacement parts necessary for post-warranty servicing at
a reasonable price. This warranty is contingent upon proper use of a Product in
the application for which it was intended and does not cover Products that were
modified without Manufacturer's approval or that were subjected by the customer
to unusual physical or electrical stress.

OTHERWISE, REGARDING THE PRODUCTS, THEIR FITNESS FOR ANY PURPOSE, THEIR QUALITY,
THEIR MERCHANTABILITY, OR OTHERWISE.

8. Report

Hakuto agrees to furnish to Manufacturer quarterly reports regarding sales to
customers or to prospective customers in the Territory.


9. Intellectual Property Rights

9.01 Property Rights. Distributor agrees that Manufacturer owns all right,
title, and interest in the product lines that include the Products and in all of
Manufacturer's patents, trademarks, trade names, inventions, copyrights,
know-how, and trade secrets relating to the design, manufacture, operation or
service of the Products. The use by Distributor of any of these property rights
is authorized only for the purposes herein set forth, and upon termination of
this Agreement for any reason such authorization shall cease.

9.02 Sale Conveys no Right to Manufacture or Copy. The Products are offered for
sale and are sold by Manufacturer subject in every case to the condition that
such sale does not convey any license, expressly or by implication, to
manufacture, duplicate or otherwise copy or reproduce any of the Products.
Distributor shall take appropriate steps with its customers, as Manufacturer may
request, to inform them of and assure compliance with the restrictions.

9.03 Confidentiality. Distributor acknowledges that by reason of its
relationship to Manufacturer hereunder it will have access to certain
information and materials concerning Manufacturer's business, plans, customers,
technology, and products that are confidential and of substantial value to
Manufacturer, which value would be impaired if such information were disclosed
to third parties. Distributor agrees that it will not use in any way for its own
account or the account of any third party, nor disclose to any third party, any
such confidential information revealed to it by Manufacturer. Distributor shall
take every reasonable precaution to protect the confidentiality of such
information. Upon request by Distributor, Manufacturer shall advise whether or
not it considers any particular information or materials to be confidential.
Distributor shall not publish any technical description of the Products beyond
the description published by Manufacturer (except to translate that description
into appropriate languages for the Territory). In the event of termination of
this Agreement, there shall be no use or disclosure by Distributor of any
confidential information of Manufacturer, and Distributor shall not manufacture
or have manufactured any devices, components or assemblies utilizing any of
Manufacturer's confidential information. Distributor expressly consents to
Manufacturer's use of Distributor's name in promotional materials and other
documents delivered to government agencies and otherwise.

9.04 Trademarks and Trade Names.

                (a) Use. During the term of this Agreement, Distributor shall
have the right to indicate to the public that it is an authorized distributor of
Manufacturer's Products and to advertise within the Territory such Products
under the trademarks, marks, and trade names that Manufacturer may adopt from
time to time ("Manufacturer's Trademarks"). Distributor shall not alter or
remove any Manufacturer's Trademark applied to the Products at the factory.
Except as set forth in this Section 9.04, nothing contained in this Agreement
shall grant to Distributor any right, title or interest in Manufacturer's
Trademarks. At no time during or after the term of this Agreement shall
Distributor challenge or assist others to challenge Manufacturer's Trademarks or
the registration thereof or attempt to register any trademarks, marks or trade
names confusingly similar to those of Manufacturer.

                (b) Approval of Representations. All representations of
Manufacturer's Trademarks that Distributor intends to use shall first be
submitted to Manufacturer for approval (which shall not be unreasonably
withheld) of design, color, and other details or shall be exact copies of those
used by Manufacturer. If any of Manufacturer's Trademarks are to be used in
conjunction with another trademark on or in relation to the Products, then
Manufacturer's mark shall be presented equally legibly, equally prominently, and
of greater size than the other but nevertheless separated from the other so that
each appears to be a mark in its own right, distinct from the other mark.

9.05 Patent, Copyright and Trademark Indemnity.

                (a) Indemnification. Distributor agrees that Manufacturer has
the right to defend, or at its option to settle, and Manufacturer agrees, at its
own expense, to defend or at its option to settle, any claim, suit or proceeding
brought against Distributor or its customer on the issue of infringement of any
United States or Japan patent, copyright or trademark by the Products sold
hereunder or the use thereof, subject to the limitations hereinafter set forth.
Manufacturer shall have sole control of any such action or settlement
negotiations, and Manufacturer agrees to pay, subject to the limitations
hereinafter set forth, any final judgment entered against Distributor or its
customer on such issue in any such suit or proceeding defended by Manufacturer.
Distributor agrees that Manufacturer at its sole


<PAGE>   5

option shall be relieved of the foregoing obligations unless Distributor or its
customer notifies Manufacturer promptly in writing of such claim, suit or
proceeding and gives Manufacturer authority to proceed as contemplated herein,
and, at Manufacturer's expense, gives Manufacturer proper and full information
and assistance to settle and/or defend any such claim, suit or proceeding. If
the Products, or any part thereof, are, or in the opinion of Manufacturer may
become, the subject of any claim, suit or proceeding for infringement of any
United States or Japan patent, copyright or trademark, or if it is
adjudicatively determined that the Products, or any part thereof, infringe any
United States or Japan patent, copyright or trademark, or if the sale or use of
the Products, or any part thereof, is, as a result, enjoined, then Manufacturer
may, at its option and expense either: (i) procure for Distributor and its
customers the right under such patent, copyright or trademark to sell or use, as
appropriate, the Products or such part thereof; or (ii) replace the Products, or
part thereof, with other suitable Products or parts; or (iii) suitably modify
the Products, or part thereof; or (iv) if the use of the Products, or part
thereof, is prevented by injunction, remove the Products, or part thereof, and
refund the aggregate payments paid therefor by Distributor, less a reasonable
sum for use and damage. Manufacturer shall not be liable for any costs or
expenses incurred without its prior written authorization.

                (b) Limitation. Notwithstanding the provisions of Subsection
9.05(a) above, Manufacturer assumes no liability for (i) infringements covering
completed equipment or any assembly, circuit, combination, method or process in
which any of the Products may be used but not covering the Products when used
alone; (ii) trademark infringements involving any marking or branding not
applied by Manufacturer or involving any marking or branding applied at the
request of Distributor; or (iii) infringements involving the modification or
servicing of the Products, or any part thereof, unless such modification or
servicing was done by Manufacturer.

                (c) Entire Liability. The foregoing provisions of this Section
9.05 state the entire liability and obligations of Manufacturer and the
exclusive remedy of Distributor and its customers, with respect to any alleged
infringement of patents, copyrights, trademarks or other intellectual property
rights by the Products or any part thereof.


10. Relationship of Parties

The relationship between Manufacturer and Hakuto shall not be that of a
principal and an agent, but shall be that of a seller and purchaser, each acting
as an independent contractor. Hakuto shall have no right or authority to incur,
assume or create, in writing or otherwise, any warranty, liability, or
obligation of any kind, express or implied, in the name of or on behalf of
Manufacturer.
