2. Waiver of Offset; Payment of Principal Amount.

(a) The Company hereby waives and relinquishes any and all rights to set off any amount due or payable by it hereunder against any obligations of the Seller or any of its Affiliates now or hereafter existing or arising under the Purchase Agreement, any Ancillary Agreement or otherwise.

(b) The Principal Amount shall be due and payable in cash on the Maturity Date.

3. Interest.

(a) The Company shall pay interest to the Holder on the Principal Amount at the rate of 8% per annum, payable in Common Stock on Conversion Dates as the Principal Amount is converted as provided in Sections 6 and 7. Beginning on the Original Issue Date and continuing until November 15, 2004, no interest shall have accrued on the portion of the Principal Amount equal to Three Million One Hundred Eighty-Eight Thousand Three Hundred Seventy-Five and no/100 Dollars ($3,188,375).

(b) Interest shall be calculated on the basis of a 365-day year and shall accrue daily commencing on the Original Issue Date. Interest paid in Underlying Shares shall be rounded up to the nearest whole share and otherwise paid as provided in Sections 6 and 7.

(c) Notwithstanding the foregoing, the Company may not pay the interest in Common Stock unless, at such time, the Equity Conditions are satisfied with respect to such Common Stock.

4. Note Register. The Company shall register this Note upon records to be maintained by the Company for that purpose (the “Note Register”) in the name of each record holder thereof from time to time. The Company may deem and treat the registered Holder of this Note as the absolute owner hereof for the purpose of any conversion hereof or any payment of interest hereon, and for all other purposes, absent actual notice to the contrary.

5. Registration of Permitted Transfers and Exchanges.

(a) No Holder shall Transfer all or any portion of this Note without the prior written consent of the Company (which consent may be withheld at the discretion of the Company), except (i) a Transfer to a spouse, children (natural or adopted), stepchildren, grandchildren or descendants or a trust for the benefit of any of them, or an entity or foundation owned by a Holder, a spouse, children (natural or adopted), stepchildren, grandchildren or descendants; or (ii) a Transfer by any Holder to an Affiliate of such Holder (any such Transfer, a “Permitted Transfer”).

(b) The Company shall register the Permitted Transfer of any portion of this Note in the Note Register upon surrender of this Note to the Company at its address for notice set forth herein. Upon any such Permitted Transfer, a new note, in substantially the form of this Note (any such new note, a “New Note”), evidencing the portion of this Note so transferred shall be issued to the transferee (each, a “Holder”) and a New Note evidencing the remaining portion of this Note not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Note by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Note. No service charge or other fee will be imposed in connection with any such registration of Permitted Transfer.

REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. ADDITIONALLY, THIS NOTE IS SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND OTHER TERMS AND CONDITIONS SET FORTH IN THE NOTE.

6. Conversion of the Principal Amount and Payment of Interest in Underlying Shares.

(a) Mandatory Conversion of Principal Amount and Payment of Interest. Subject to limitations set forth in this Section 6 and in accordance with the procedures set forth in Section 7, following the Initial Conversion Event, this Note shall be payable and convertible on successive Conversion Dates in installments of Underlying Shares, each of which installment shall equal the Conversion and Interest Payment Amount. The Conversion and Interest Payment Amount on each Conversion Date will be applied first to payment of accrued and unpaid interest and then to conversion of the Principal Amount. Subject to the limitations expressed in the first sentence of this subsection 6(a), the Conversion and Interest Payment Amount shall automatically convert into and be payable with Underlying Shares on each Conversion Date (in each case based on the Conversion Share Amount and Conversion Price applicable to such Conversion Date). The Principal Amount shall not convert into Underlying Shares, and interest shall not be paid in the form of Underlying Shares, except in each case as provided in this Section 6.

(b) Conversion Schedule. On each Conversion Date, the Company shall deliver a Conversion Notice to the Holder and the Transfer Agent, instructing the Transfer Agent to issue the Converted Shares to the Holder at the address specified in writing by the Holder to the Company from time to time together with a schedule in the form of Schedule I attached hereto (the “Conversion Schedule”).

(i) Notwithstanding anything to the contrary contained herein, this Note shall not be convertible to the extent that such conversion or exercise would result in the Holder owning more than 4.99% of the outstanding shares of the Common Stock of the Issuer at the date of conversion, other than in connection with a Fundamental Transaction as contemplated in Section 12(b).

(ii) Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by the Holder upon any conversion of, or payment of interest on, this Note (or otherwise in respect hereof) shall be limited to the extent necessary to insure that the voting power represented by the Underlying Shares into which this Note may be converted or with which interest may be paid (together with all Underlying Shares into which this Note shall theretofore have been converted and with which interest shall theretofore have been paid) will not exceed 19.9% of the voting power represented by all of the issued and outstanding shares of Common Stock of the Company before such conversion.

(iii) If a conversion or payment of interest hereunder may not be effected in full due to the application of this Section 6(c), the Company shall honor and effect such conversion and interest payment to the extent permissible hereunder and shall promptly deliver to the Holder a Conversion Schedule indicating the Principal Amount which has not been converted.

(d) Equity Conditions. Notwithstanding anything contained in this Section 6 to the contrary, if the Equity Conditions are not satisfied on any Conversion Date, then the payment of interest and conversion under subsection 6(a) shall not occur on such Conversion Date, and such day shall no longer be considered a Conversion Date for any purpose. Subject to the terms of this Note, the Installment Period that, in the absence of the failure to satisfy the Equity Conditions, would have commenced on the Monday of the week in which the former Conversion Date occurred shall instead commence on the first Monday occurring at least five Trading Days after the date on which the Equity Conditions are next satisfied, and the next Conversion Date would be the first Trading Day of such Installment Period; provided that, if the Floor Price shall exceed the Conversion Price on two consecutive Conversion Dates during the Term, item (vii) of the Equity Conditions shall thereafter not be considered in determining whether the Equity Conditions shall have been satisfied.

For example, subject to the foregoing proviso, if accrued interest on this Note were to be paid and a part of the Principal Amount were to convert on Monday September 13, 2004 in accordance with this Section 6, then such date would be a Conversion Date. If on such date the Equity Conditions are not satisfied, no such

payment of interest or conversion would occur on such Conversion Date, and in such event, that day would no longer be a Conversion Date for any purpose. In this example, the Equity Conditions are assumed to be next satisfied on Friday September 17, 2004. Subject to the terms of this Note, the Installment Period that, in the absence of the aforementioned condition, would have commenced on September 13, 2004, would instead commence on Monday, September 27, 2004, and the Conversion Date shall be the first Trading Day of that Installment Period.

(e) Option to pay in Cash. Notwithstanding anything contained in this Section 6 to the contrary, the Company may pay cash in lieu of issuing Underlying Shares on conversion of the Principal Amount or payment of accrued interest thereon on any Conversion Date without advance notice, so long as such cash payment is greater than or equal to the applicable Conversion and Interest Payment Amount.

7. Mechanics of Conversion.

(a) The number of Underlying Shares issuable on each Conversion Date as provided in Section 6 shall equal the Conversion and Interest Payment Amount, divided by the Conversion Price on that Conversion Date (for each conversion, the “Converted Shares”).

(b) Upon each conversion of this Note, the Company shall promptly (but in no event later than the second Trading Day following each Conversion Notice) issue or cause to be issued and cause to be delivered to or upon the written order of the Holder a certificate representing the Converted Shares issuable upon such conversion, bearing the following legend, if applicable:

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO FINISAR CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.

(c) Notwithstanding subsection (b) above, the Company shall, if requested by the Holder in connection with one or more Conversion Dates, cause its legal counsel to consult with the Company’s transfer agent with a view to causing the certificates representing Converted Shares to be issued without restrictive legends in accordance with applicable laws and regulations. The Holder agrees, at the Company’s expense, to cooperate with the Company in this regard and to execute certificates, questionnaires and any other documents reasonably requested by the Company’s legal counsel for such purpose.

(d) The Holder shall be deemed to have become holder of record of such Converted Shares as of the Conversion Date.

(e) The Holder shall not deliver the original Note upon a conversion hereunder, except upon the final conversion resulting in payment of the Principal Amount and accrued interest in full, at which time Holder shall deliver this Note marked “Cancelled — Paid in Full.” Rather, execution and delivery of the Conversion Notice shall have the same effect as a prepayment of a portion of the Principal Amount to the extent converted by the issuance of Conversion and Interest Payment Amounts as provided in Section 6.

8. Prepayments. At any time following the Original Issue Date and prior to the Maturity Date, upon delivery of a written notice to the Holder (a “Prepayment Notice” and the date such notice is delivered by the Company, the “Prepayment Notice Date”), the Company shall be entitled to prepay in cash all or any part of the Principal Amount (together with the accrued and unpaid interest in the portion so prepaid). Once delivered, the Company shall not be entitled to rescind a Prepayment Notice. The prepayment shall be due on the 5^th Trading Day immediately following the Prepayment Notice Date.

9. Events of Default.

(a) “Event of Default” means any default by the Company in the payment or conversion (free of any claim of subordination) of the Principal Amount or interest thereon, as and when the same becomes due and payable (whether on a Conversion Date or the Maturity Date or by acceleration or prepayment or otherwise).

(b) At any time or times following the occurrence of an Event of Default, the Holder shall have the

option to elect, by notice to the Company (an “Event Notice”), to require the Company to repurchase all or any portion of the Principal Amount, at a repurchase price equal to the balance thereof, plus all accrued but unpaid interest thereon, through the date of payment. The aggregate amount payable pursuant to the preceding sentence is referred to as the “Event Price.” The Company shall pay the aggregate Event Price to the Holder no later than the third Trading Day following the date of delivery of the Event Notice, and upon receipt thereof the Holder shall deliver the original Note.

(c) Upon the occurrence of any Bankruptcy Event, all of the Principal Amount and accrued but unpaid interest thereon shall immediately become due and payable in full in cash, without any further action by the Holder, and the Company shall immediately be obligated to repurchase this Note at the Event Price pursuant to the preceding paragraph as if the Holder had delivered an Event Notice immediately prior to the occurrence of such Bankruptcy Event.

(d) In connection with any Event of Default, the Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Any such declaration may be rescinded and annulled by the Holder at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereto.

10. Charges, Taxes and Expenses. Issuance of certificates for Converted Shares shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Converted Shares or this Note in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Note or receiving Converted Shares in respect hereof (including receiving the Converted Shares in full or partial payment of the purchase price under the Purchase Agreement).

11. Reservation of Underlying Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Underlying Shares as required hereunder, the number of Underlying Shares which are then issuable and deliverable upon the conversion of (and otherwise in respect of) this entire Note (taking into account the adjustments contemplated by Section 12), free from preemptive rights or any other contingent purchase rights of persons other than the Holder. The Company covenants that all Underlying Shares so issuable and deliverable shall, upon issuance in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. The Company covenants that, once the Registration Statement becomes effective, it shall keep the Registration Statement effective as agreed in the Purchase Agreement.

12. Certain Adjustments. Certain provisions of this Note are subject to adjustment from time to time as set forth in this Section 12.

(a) Stock Dividends and Splits. If the Company, (i) pays or declares a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case an equitable adjustment shall be made such that (A) the Floor Price shall be proportionately adjusted to reflect such event, (B) the Conversion Share Amount, if such event shall occur during a Reference Period, shall be proportionately adjusted to reflect such event and (C) the Conversion Price shall be proportionately and equitably adjusted if, and only if, the effective date for such event is Conversion Date or one of the three Trading Days to be used for the determination of the Conversion Price. Any adjustment made pursuant to this paragraph shall become effective immediately after the agreed determination of the Company and the Holder.

(b) Fundamental Transactions. If, at any time while this Note is outstanding, (i) the Company effects any merger or consolidation of the Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, (iv) the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any

class of capital stock of the Company (other than any dividends, distributions and other transactions to which Section 12(a) applies and ordinary dividends and distributions paid exclusively in cash) or evidences of its indebtedness or other assets, including securities, or (v) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 12(a) above) (in any such case, a “Fundamental Transaction”), then upon any subsequent conversion of this Note, the Holder shall have the right to receive, for each Underlying Share that would have been issuable upon such conversion absent such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the “Alternate Consideration”). For purposes of any such conversion, the Company shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction must issue to the Holder a new note consistent with the foregoing provisions and evidencing the Holder’s right to convert such note into Alternate Consideration and deliver an undertaking pursuant to which it will assume the obligation to comply with the provisions of Sections 8.3, 8.4 and 8.9 and Article XIII of the Purchase Agreement with respect to such Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms (i) requiring any such successor or surviving entity to comply with the provisions of this paragraph (b), (ii) providing that the issuance price of such Alternate Consideration shall at the time of issuance be based on the principles upon which the Underlying Shares are priced hereunder and (iii) insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. Notwithstanding the foregoing, if the Alternate Consideration is cash or is not freely saleable by Holder without restriction under the Securities Act then upon the consummation of such transaction the Holder may elect to convert the Principal Amount and receive cash in connection with such Fundamental Transaction or to have the then Principal Amount (together with all accrued but unpaid interest thereon) paid to it in full in cash in connection with such Fundamental Transaction.

(c) Calculations. All calculations under this Section 12 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

(d) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 12, the Company at its expense will promptly compute such adjustment in accordance with the terms hereof and prepare a certificate describing in reasonable detail such adjustment and the transactions giving rise thereto, including all facts upon which such adjustment is based.
