Delaware corporations may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an
action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys&#146; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such
action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable
cause to believe the person&#146;s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption
that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe
that the person&#146;s conduct was unlawful. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;145(b) of the DGCL states that Delaware corporations may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys&#146;
fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests
of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which the person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of
Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity
for such expenses as the Delaware Court of Chancery or such other court shall deem proper. </P>

a Delaware corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a)&nbsp;and (b) of Section&nbsp;145, or in defense of any claim, issue or matter therein, such person

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;145(d) of the DGCL states that any indemnification under subsections (a)&nbsp;and (b) of Section&nbsp;145 (unless ordered by a court) shall be
made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard
of conduct set forth in subsections (a)&nbsp;and (b) of Section&nbsp;145. Such determination shall be made with respect to a person who is a director or officer at the time of such determination (1)&nbsp;by a majority vote of the directors who are
not parties to such action, suit or proceeding, even though less than a quorum, (2)&nbsp;by a committee of such directors designated by majority vote of such directors, even though less than a quorum, (3)&nbsp;if there are no such directors, or if

entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person&#146;s official capacity and as to action in another capacity while holding such office. </P>

any liability asserted against such person and incurred by such person in any such capacity or arising out of such person&#146;s status as such, whether or not the corporation would have the power to indemnify such person against such liability

duty of loyalty to the corporation or its stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;for willful or negligent conduct in paying dividends or
repurchasing stock out of other than lawfully available funds, or (4)&nbsp;for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or
omission occurring prior to the date when such provision becomes effective. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;102(b)(7) of the DGCL further authorizes exculpation of certain

individual identified in the corporation&#146;s public filings with the Commission as a named executive officer; and (iii)&nbsp;an individual who, by written agreement with the corporation, has consented to be identified as an officer for purposes
of accepting service of process (&#147;Covered Officers&#148;). Such exculpation may not eliminate or limit the liability of a Covered Officer (1)&nbsp;for any breach of such Covered Officer&#146;s duty of loyalty to the corporation or its
stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;for any transaction from which the Covered Officer derived an improper personal benefit, or (4)&nbsp;for

Incorporation (the &#147;Certificate of Incorporation&#148;) provides that no director shall be personally liable for breach of fiduciary duty as a director, provided, however that such clause shall not apply to any liability of a director
(1)&nbsp;for any breach of the director&#146;s duty of loyalty to Ciena or its stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;liability under
Section&nbsp;174 of the DGCL, or (4)&nbsp;for any transaction from which the director derived an improper personal benefit. In addition, Ciena&#146;s Bylaws provide that Ciena shall indemnify the persons entitled to be indemnified to the fullest
extent permitted by the DGCL. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Certificate of Incorporation also provides exculpation to Covered Officers for personal liability for monetary damages
in connection with direct claims brought by stockholders for breach of fiduciary duty of care, including class actions (the &#147;Exculpation Provision&#148;). The Exculpation Provision does not exculpate such the Covered Officers&#146; personal
liability for monetary damages for breach of fiduciary duty of care claims brought by Ciena or for derivative claims brought by stockholders in the right of Ciena. Accordingly, Ciena and its stockholders still have the ability to hold officers
accountable for wrongdoing. In addition, the Exculpation Provision does not limit the liability of Covered Officers for: (i)&nbsp;a breach of the duty of loyalty; (ii)&nbsp;acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; or (iii)&nbsp;any transaction from which a Covered Officer derived an improper personal benefit. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Indemnification
