duty of care, it enables corporations to limit available relief to equitable remedies such as
injunction or rescission. The statute has no effect on a director&#146;s duty of loyalty or liability

shall indemnify its directors, officers, employees and agents to the full extent permitted by the
General Corporation Law of the State of Delaware, including in circumstances in which
indemnification is otherwise discretionary under such law. In addition, with the approval of the
Board of Directors and the stockholders, the Registrant has entered into separate indemnification
agreements with its directors, officers and certain employees which require the Registrant, among
other things, to indemnify them against certain liabilities which may arise by reason of their
status or service (other than liabilities arising from willful misconduct of a culpable nature) and
to obtain directors&#146; and officers&#146; insurance, if available on reasonable terms.

final court approval of the settlement, the United States Court of Appeals vacated the class
certification of the plaintiff&#146;s claims against the underwriters in related test cases, and the
proposed settlement was thereafter withdrawn. Should the litigation proceed, these officers are
likely to assert claims for indemnification. Certain current or former officers and directors of
the Registrant also have been named as defendants in a derivative lawsuit in which the plaintiffs
have alleged that certain current or former officers and directors of the Registrant caused it to
grant stock options at less than fair market value, contrary to its public statements (including
its financial statements), and that, as a result, those officers and directors are liable to the
Registrant. These current or former officers and directors either have asserted or are likely to
assert a claim for indemnification in connection with this litigation. Other than the securities
class action litigation and the stock option derivative litigation, there is no pending litigation
or proceeding involving a director, officer, employee or other agent of the Registrant in which
indemnification is being sought nor is the Registrant aware of any threatened litigation that may
result in a claim for indemnification by any director, officer, employee or other agent of the
Registrant.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act may be permitted
to directors, officers and controlling persons of the registrant pursuant to the foregoing
provisions, 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 such director, officer or controlling person in connection with the
securities being registered, 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.

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 3.
Incorporation of Documents by Reference
Finisar Corporation (the "Registrant") hereby incorporates by reference in this registration
statement the following documents previously filed with the Securities and Exchange Commission (the
"Commission"):
(a) The Registrant's latest annual report on Form 10-K filed pursuant to Sections 13(a) or
15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), containing audited
financial statements for the Registrant's latest fiscal year ended April 30, 2008, as filed with
the Commission on June 30, 2008.
(b) All other reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act since the
end of the fiscal year covered by the Registrant's annual report referred to in (a) above.
(c) The Registrant's Registration Statement on Form 8-A filed with the Commission on
November 8, 1999 pursuant to Section 12(g) of the Exchange Act, in which there is described the
terms, rights and provisions applicable to the Registrant's Common Stock.
All documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and
15(d) of the Exchange Act, prior to the filing of a post-effective amendment to this registration
statement which indicates that all securities offered hereby have been sold or which deregisters
all securities remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such documents.
Item 4.
Description of Securities
The class of securities to be offered is registered under Section 12 of the Exchange Act.
Item 5.
Interests of Named Experts and Counsel
Inapplicable.
Item 6.
Indemnification of Directors and Officers
Section 102(b) of the General Corporation Law of the State of Delaware authorizes a
corporation to provide in its certificate of incorporation that a director of the corporation shall
not be personally liable to a corporation or its stockholders for monetary damages for breach or
alleged breach of the director's "duty of care." While this statute does not change a director's
duty of care, it enables corporations to limit available relief to equitable remedies such as
injunction or rescission. The statute has no effect on a director's duty of loyalty or liability
for acts or omissions not in good faith or involving intentional misconduct or knowing violations
of law, illegal payment of dividends or stock redemptions or repurchases, or
Table of Contents
for any transaction from which the director derives an improper personal benefit. As permitted
by the statute, the Registrant has adopted provisions in its Certificate of Incorporation which
eliminate to the fullest extent permissible under Delaware law the personal liability of its
directors to the Registrant and its stockholders for monetary damages for breach or alleged breach
of their duty of care.
Section 145 of the General Corporation Law of the State of Delaware permits indemnification of
officers, directors and other corporate agents under certain circumstances and subject to certain
limitations. The Registrant's Certificate of Incorporation and Bylaws provide that the Registrant
shall indemnify its directors, officers, employees and agents to the full extent permitted by the
General Corporation Law of the State of Delaware, including in circumstances in which
indemnification is otherwise discretionary under such law. In addition, with the approval of the
Board of Directors and the stockholders, the Registrant has entered into separate indemnification
agreements with its directors, officers and certain employees which require the Registrant, among
other things, to indemnify them against certain liabilities which may arise by reason of their
status or service (other than liabilities arising from willful misconduct of a culpable nature) and
to obtain directors' and officers' insurance, if available on reasonable terms.
Section 145 of the General Corporation Law of the State of Delaware provides for
indemnification in terms sufficiently broad to indemnify such individuals, under certain
circumstances, for liabilities (including reimbursement of expenses incurred) arising under the
Securities Act.
The Registrant's executive Chairman of the Board, its former Chief Technical Officer and its
Senior Vice President—Finance and Chief Financial Officer have been named as defendants in a
securities class action lawsuit filed against the Registrant and an underwriter in the Registrant's
initial public offering in November 1999 and a secondary offering in April 2000. Although the
parties reached an agreement in principle with respect to the settlement of the litigation, before
final court approval of the settlement, the United States Court of Appeals vacated the class
certification of the plaintiff's claims against the underwriters in related test cases, and the
proposed settlement was thereafter withdrawn. Should the litigation proceed, these officers are
likely to assert claims for indemnification. Certain current or former officers and directors of
the Registrant also have been named as defendants in a derivative lawsuit in which the plaintiffs
have alleged that certain current or former officers and directors of the Registrant caused it to
grant stock options at less than fair market value, contrary to its public statements (including
its financial statements), and that, as a result, those officers and directors are liable to the
Registrant. These current or former officers and directors either have asserted or are likely to
assert a claim for indemnification in connection with this litigation. Other than the securities
class action litigation and the stock option derivative litigation, there is no pending litigation
or proceeding involving a director, officer, employee or other agent of the Registrant in which
indemnification is being sought nor is the Registrant aware of any threatened litigation that may
result in a claim for indemnification by any director, officer, employee or other agent of the
Registrant.
The Registrant has obtained liability insurance for the benefit of its directors and officers.

Exhibits
See Exhibit Index.
Item 9.
Undertakings
The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the
registration statement (or the most recent post-effective amendment thereof) which, individually or
in the aggregate, represent a fundamental change in the information set forth in the registration
statement; and
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change to such information in
the registration statement;
provided
,
however
, that paragraphs (1)(i) and (l)(ii) do not apply if the
information required to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange
Act that are incorporated by reference in the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
The undersigned registrant hereby undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new registration statement relating
to the securities offered therein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.
Table of Contents
Insofar as indemnification for liabilities arising under the Securities Act may be permitted
to directors, officers and controlling persons of the registrant pursuant to the foregoing
provisions, 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 such director, officer or controlling person in connection with the
securities being registered, 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.
