indemnify its directors, officers, employees and agents and its former directors, officers,
employees and agents and those who serve, at the corporation&#146;s request, in such capacities with
another enterprise, against expenses (including attorneys&#146; fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in connection with the
defense of any action, suit or proceeding in which they or any of them were or are made parties or
are threatened to be made parties by reason of their serving or having served in such capacity. The
DGCL provides, however, that such person must have acted in good faith and in a manner such person
reasonably believed to be in (or not opposed to) the best interests of the corporation and, in the
case of a criminal action, such person must have had no reasonable cause to believe his or her
conduct was unlawful. In addition, the DGCL does not permit indemnification in an action or suit by
or in the right of the corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person fairly and reasonably is
entitled to indemnity for costs the court deems proper in light of liability adjudication.
Indemnity is mandatory to the extent a claim, issue or matter has been successfully defended.

Certificate&#148;) contains provisions that provide that no director of Ciena shall be liable for breach
of fiduciary duty as a director, except for: (1)&nbsp;any breach of the directors&#146; duty of loyalty to
Ciena or its stockholders; (2)&nbsp;acts or omissions not in good faith or which involve intentional

contains provisions that further provide for the indemnification of directors and officers to the
fullest extent permitted by the DGCL. Under the bylaws of Ciena, Ciena is required to advance
expenses incurred by an officer or director in defending any such action if the director or officer
undertakes to repay such amount if it is determined that the director or officer is not entitled to
indemnification. In addition, Ciena has entered into indemnification agreements with each of its
directors and executive officers pursuant to which Ciena has agreed to indemnify such persons as
permitted by the DGCL. Ciena has obtained directors&#146; and officers&#146; liability insurance against

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;To file, during any period in which offers or sales are being made, a post-effective

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act of 1933;

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. Notwithstanding the foregoing, any increase or decrease in volume of securities offered
(if the total dollar value of securities offered would not exceed that which was registered) and
any deviation from the low or high end of the estimated maximum offering range may be reflected in
the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20&nbsp;percent change in the maximum aggregate
offering price set forth in the &#147;Calculation of Registration Fee&#148; table in the effective
registration statement; and

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 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 Act and
will be governed by the final adjudication of such issue.

Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Under Section 145 of the Delaware General Corporation Law ("DGCL"), a corporation may
indemnify its directors, officers, employees and agents and its former directors, officers,
employees and agents and those who serve, at the corporation's request, in such capacities with
another enterprise, against expenses (including attorneys' fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in connection with the
defense of any action, suit or proceeding in which they or any of them were or are made parties or
are threatened to be made parties by reason of their serving or having served in such capacity. The
DGCL provides, however, that such person must have acted in good faith and in a manner such person
reasonably believed to be in (or not opposed to) the best interests of the corporation and, in the
case of a criminal action, such person must have had no reasonable cause to believe his or her
conduct was unlawful. In addition, the DGCL does not permit indemnification in an action or suit by
or in the right of the corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person fairly and reasonably is
entitled to indemnity for costs the court deems proper in light of liability adjudication.
Indemnity is mandatory to the extent a claim, issue or matter has been successfully defended.
The Third Restated Certificate of Incorporation, as amended, of Ciena (the "Ciena
Certificate") contains provisions that provide that no director of Ciena shall be liable for breach
of fiduciary duty as a director, except for: (1) any breach of the directors' duty of loyalty to
Ciena or its stockholders; (2) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of the law; (3) liability under Section 174 of the DGCL; or (4)
any transaction from which the director derived an improper personal benefit. The Ciena Certificate
contains provisions that further provide for the indemnification of directors and officers to the
fullest extent permitted by the DGCL. Under the bylaws of Ciena, Ciena is required to advance
expenses incurred by an officer or director in defending any such action if the director or officer
undertakes to repay such amount if it is determined that the director or officer is not entitled to
indemnification. In addition, Ciena has entered into indemnification agreements with each of its
directors and executive officers pursuant to which Ciena has agreed to indemnify such persons as
permitted by the DGCL. Ciena has obtained directors' and officers' liability insurance against
certain liabilities, including liabilities under the Securities Act.

Item 9. Undertakings.
(a) 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 of 1933;
(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. Notwithstanding the foregoing, any increase or decrease in volume of securities offered
(if the total dollar value of securities offered would not exceed that which was registered) and
any deviation from the low or high end of the estimated maximum offering range may be reflected in
the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the maximum aggregate
offering price set forth in the "Calculation of Registration Fee" table in the effective
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 (a)(1)(i) and (a)(1)(ii) do not apply if the registration
statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports filed with or
furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act that are incorporated by reference in the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, 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.
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant
to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities
Exchange Act of 1934) 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.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 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 Act and
will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it

has duly caused this Registration Statement to be signed on its behalf by the undersigned,
