wholly-owned subsidiary of Finisar (“Sub”), and InterSAN, Inc., a Delaware
corporation (“InterSAN”).

RECITALS

     WHEREAS, the Boards of Directors of Finisar, Sub and InterSAN deem it
advisable and in the best interests of each corporation and its respective
stockholders that Finisar and InterSAN combine in order to advance the long-term
business interests of Finisar and InterSAN;

     WHEREAS, the combination of Finisar and InterSAN shall be effected by the
terms of this Agreement through a transaction (the “Merger”) in which Sub will
merge with and into InterSAN, InterSAN will become a wholly-owned subsidiary of
Finisar and the stockholders of InterSAN will become stockholders of Finisar;
and

     WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the “Code”).

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
parties agree as follows:

ARTICLE I

THE MERGER

     Section 1.1 Effective Time of the Merger. Subject to the provisions of this
Agreement, a Certificate of Merger (the “Certificate of Merger”) in
substantially the form attached hereto as Exhibit A as required by the relevant
provisions of the Delaware General Corporation Law (the “DGCL”) shall be duly
executed and acknowledged by Sub and by InterSAN as the Surviving Corporation
(as defined in Section 1.3(a)) and delivered to the Delaware Secretary of State
for filing on, or as soon as practicable after, the Closing Date (as defined in
Section 1.2). The Merger shall become effective upon the filing of the
Certificate of Merger with the Delaware Secretary of State (the “Effective
Time”).

     Section 1.2 Closing. The closing of the Merger (the “Closing”) will take
place at 8:00 a.m., Pacific Time, on a date to be specified by Finisar and
InterSAN (the “Closing Date”), which shall be no later than the second business
day after satisfaction of the latest to occur of the conditions set forth in
Article VII of this Agreement (other than those conditions which by their nature
will be satisfied on the Closing Date), at the offices of DLA Piper Rudnick Gray
Cary US LLP, 2000 University Avenue, East Palo Alto, CA 94303-2248 unless
another date or place is agreed to in writing by Finisar and InterSAN.

          (a) At the Effective Time (i) Sub shall be merged with and into
InterSAN (the “Surviving Corporation”) and the separate existence of Sub shall
cease, (ii) the Certificate of Incorporation of InterSAN, as the Surviving

of Incorporation of Sub as in effect immediately prior to the Effective Time,
except that Article I of such Certificate of Incorporation shall be amended to
read as follows: “The name of the corporation is InterSAN, Inc.” and (iii) the
Bylaws of InterSAN, as the Surviving Corporation, shall be amended and restated

          (b) At and after the Effective Time, the Surviving Corporation shall

each of the Constituent Corporations, and all real, personal and mixed property,
and all liabilities, obligations and debts due to either of the Constituent
Corporations on whatever account, as well as for stock subscriptions and all
other things in action or belonging to each of the Constituent Corporations,
shall be vested in the Surviving Corporation, and all assets, property, rights,
privileges, powers and franchises, and all and every other interest shall be
thereafter as effectually the property of the Surviving Corporation as they were
of the Constituent Corporations, and the title to any real estate vested by deed
or otherwise, in either of the Constituent Corporations, shall not revert or be
in any way impaired, but all rights of creditors and all Liens (as hereinafter
defined) upon any property of either of the Constituent Corporations shall be
preserved unimpaired, and all obligations, debts, liabilities and duties of the
Constituent Corporations shall thereafter attach to the Surviving Corporation
and may be enforced against it to the same extent as if such obligations, debts,
liabilities and duties had been incurred by it.

     Section 1.4 Directors and Officers. The directors and officers of Sub
immediately prior to the Effective Time shall be the directors and officers of
the Surviving Corporation at the Effective Time, each of whom will hold office
in accordance with the Certificate of Incorporation and Bylaws of the Surviving
Corporation, in each case until their respective successors are duly elected or
appointed.

cancelled and retired and shall cease to exist, and each holder of a certificate
representing any such shares shall cease to have any rights with respect
thereto, except rights as a holder of the shares of Finisar Common Stock into
which the InterSAN Capital Stock has been converted and the right to receive any
cash in lieu of fractional shares of Finisar Common Stock to be issued or paid
in consideration therefor upon the surrender of such certificate in accordance
with Section 2.3, without interest, or to exercise their dissenter’s rights as
set forth in Section 2.5 hereof.

4

--------------------------------------------------------------------------------

 

          (c) InterSAN Warrants. At the Effective Time, all then outstanding
warrants to purchase InterSAN Capital Stock (each, an “InterSAN Warrant”) which
are not exercised or do not otherwise expire as of the Effective Time shall be
assumed by Finisar and converted into a warrant (an “Assumed Warrant”) to
acquire, on the same terms and conditions as were applicable under the InterSAN
Warrant, such number of shares of Finisar Common Stock which the holder of such
InterSAN Warrant would have been entitled to receive pursuant to the Merger
pursuant to Section 2.2(b) if the InterSAN Warrant had been exercised prior to
the Effective Time (rounded down to the nearest whole share) at a price per
share (rounded up to the nearest whole cent) equal to (i) the aggregate exercise
price of the InterSAN Capital Stock purchasable pursuant to such InterSAN
Warrant immediately prior to the Effective Time divided by (ii) the number of
full shares of Finisar Common Stock purchasable pursuant to the Assumed Warrant.

     Section 2.3 Exchange of Certificates. The procedures for exchanging
outstanding shares of InterSAN Capital Stock for Finisar Common Stock and cash
pursuant to the Merger are as follows:

          (a) Exchange Agent. Promptly after the Effective Time, Finisar shall
cause to be deposited with an exchange agent designated by Finisar (the
“Exchange Agent”), for exchange in accordance with this Section 2.3, through the
Exchange Agent, shares of Finisar Common Stock issuable and payable to the
holders of InterSAN Capital Stock pursuant to Section 2.2, less the Escrow
Shares issuable and deliverable to the Escrow Agent pursuant to Section 2.4
(such shares of Finisar Common Stock, together with any dividends or
distributions with respect thereto, being hereinafter referred to as the
“Exchange Fund”), in exchange for outstanding shares of InterSAN Capital Stock.

          (b) Exchange Procedures. Upon surrender by a holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of InterSAN Capital Stock (each a “Certificate”
and, collectively, the “Certificates”) whose shares were converted pursuant to
Section 2.2 into shares of Finisar Common Stock, together with (i) a duly
executed letter of transmittal (in a form to be provided by Finisar prior to the
Closing), which shall specify that delivery shall be effected, and risk of loss
and title to the Certificates shall pass, only upon delivery of the Certificates
to the Exchange Agent and shall be in such form and have such other provisions
as Finisar and InterSAN may reasonably specify, and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for shares of Finisar
Common Stock, the holder of such Certificate shall be entitled to receive in
exchange therefor the number of whole shares of Finisar Common Stock into which
such InterSAN Capital Stock has been converted pursuant to the provisions of
Section 2.2 less the number of whole Escrow Shares in respect of such InterSAN
Capital Stock that is placed in escrow pursuant to Section 2.4. The Certificates
so surrendered shall immediately be canceled. If requested by a holder of record
of InterSAN Capital Stock in the letter of transmittal delivered to Finisar,
Finisar shall cause the shares of Finisar Common Stock issued in exchange for
the shares of InterSAN Capital Stock to be transferred by book entry to an
account established by such holder at a broker to be identified by InterSAN who
shall be reasonably acceptable to Finisar. If requested by a holder of InterSAN
Common Stock acquired upon the exercise of an InterSAN Option for which InterSAN
is obligated to withhold federal or state taxes, Finisar shall retain the number
of shares of Finisar Common Stock otherwise issuable to such holder equal to the
amount of InterSAN’s statutory tax withholding obligations in complete
satisfaction of the

5

--------------------------------------------------------------------------------

 

holder’s liability therefor to InterSAN and Finisar. In the event of a transfer
of ownership of InterSAN Capital Stock which is not registered in the transfer
records of InterSAN, the shares of Finisar Common Stock to which the holder is
entitled may be issued to a transferee if the Certificate representing such
InterSAN Capital Stock is presented to the Exchange Agent accompanied by all
documents required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.3, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the shares of Finisar Common Stock and cash in lieu of any fractional
shares of Finisar Common Stock as contemplated by this Section 2.3.

          (c) InterSAN Restricted Stock. Notwithstanding the foregoing, if any
unvested shares of InterSAN Capital Stock subject to a right of repurchase by
InterSAN (“InterSAN Restricted Stock”) remain outstanding immediately prior to
the Effective Time, subject to the surrender of the Certificate or Certificates
representing such shares of the InterSAN Restricted Stock in accordance with the
foregoing terms of this Section 2.3, the shares of Finisar Common Stock into
which such shares of InterSAN Restricted Stock are converted shall be held by
the Secretary of Finisar subject to the terms and conditions of the agreement(s)
between such holders and InterSAN (the “Restricted Stock Agreements”) until the
expiration of the right of repurchase to which such shares of InterSAN
Restricted Stock were subject thereunder, and Finisar shall cause the Secretary
of Finisar to release such number of shares of Finisar Common Stock to the
former holder of InterSAN Restricted Stock from time to time and at such time as
such right of repurchase expires pursuant to, and in accordance with, the terms
and conditions of the Restricted Stock Agreements.

          (d) Distributions with Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the Effective Time with respect to
Finisar Common Stock with a record date after the Effective Time shall be paid
to the holder of any unsurrendered Certificate with respect to the shares of
Finisar Common Stock represented thereby and no cash payment in lieu of
fractional shares payable to any such holder pursuant to subsection (f) below
shall be paid until the holder of record of such Certificate shall surrender
such Certificate. Subject to the effect of applicable laws, following surrender
of any such Certificate, there shall be paid to the record holder of the whole
shares of Finisar Common Stock issued in exchange for such Certificate, without
interest, (i) at the time of such surrender, the amount of any cash payable in
lieu of a fractional share of Finisar Common Stock to which such holder is
entitled pursuant to subsection (f) below and the amount of dividends or other
distributions with a record date after the Effective Time previously paid with
respect to such whole shares of Finisar Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to surrender and a payment date
subsequent to surrender payable with respect to such whole shares of Finisar
Common Stock.

          (e) No Further Ownership Rights in InterSAN Capital Stock. All shares
of Finisar Common Stock delivered upon the surrender for exchange of shares of
InterSAN Capital Stock in accordance with the terms hereof (including any cash
paid pursuant to subsection (d) or (f) of this Section 2.3) shall be deemed to
have been delivered in full satisfaction of all rights pertaining to such shares
of InterSAN Capital Stock, and there shall be no further registration of
transfers on the stock transfer books of the Surviving Corporation of the shares
of InterSAN

6

--------------------------------------------------------------------------------

 

Capital Stock which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Section 2.3.

          (f) No Fractional Shares. No fractional shares of Finisar Common Stock
shall be issued upon the surrender for exchange of Certificates, and such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a shareholder of Finisar. Notwithstanding any other provision of this
Agreement, each holder of shares of InterSAN Capital Stock exchanged pursuant to
the Merger who would otherwise have been entitled to receive a fraction of a
share of Finisar Common Stock (after taking into account all Certificates
delivered by such holder) shall receive, in lieu thereof, cash (without
interest) in an amount equal to such fractional part of a share of Finisar
Common Stock multiplied by the Finisar Share Price.

          (g) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the stockholders of InterSAN after one year after
the Effective Time shall be delivered to Finisar, upon demand, and any
stockholders of InterSAN who have not previously complied with this Section 2.3
shall thereafter look only to Finisar for payment of their claim for Finisar
Common Stock, any cash in lieu of fractional shares of Finisar Common Stock, and
any dividends or distributions with respect to Finisar Common Stock.

          (h) No Liability. Neither the Exchange Agent, Finisar nor InterSAN
shall be liable to any holder of shares of InterSAN Capital Stock or Finisar
Common Stock, as the case may be, for such shares (or dividends or distributions
with respect thereto) delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

          (i) Lost Certificates. In the event any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed, Finisar shall
issue in exchange for such lost, stolen or destroyed Certificate the shares of
Finisar Common Stock issuable in exchange therefor pursuant to the provisions of
this Article II, together with cash, if any, in lieu of fractional shares in
accordance with Section 2.3(f) hereof. The Board of Directors of Finisar may in
its discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed Certificate to provide to Finisar an
indemnity agreement against any claim that may be made against Finisar with
respect to the Certificate alleged to have been lost, stolen or destroyed.

     Section 2.4 Escrow.

          (a) At the Closing, or as soon as practicable after the Effective
Time, Finisar will cause to be deposited into escrow (the “Escrow”) certificates
representing the Escrow Shares. The Escrow Shares shall be held by U.S. Bank
Trust National Association or such other financial institution as Finisar and
InterSAN shall mutually determine (the “Escrow Agent”) in accordance with and
subject to the provisions of an Escrow Agreement substantially in the form of
Exhibit B hereto (the “Escrow Agreement”). The Escrow Shares shall be deemed to
have been contributed only by holders of issued and outstanding InterSAN Capital
Stock immediately prior to the Effective Time (“InterSAN Stockholders”). The
percentage of the Escrow Shares contributed on behalf of each holder of InterSAN
Common Stock contributing to the Escrow, as shown in a schedule to be delivered
at the Closing and attached to the Escrow Agreement, shall

7

--------------------------------------------------------------------------------

 

be ten percent (10%) of the shares of Finisar Common Stock entitled to be
received by each such holder of InterSAN Common Stock at the Effective Time;
provided, however, that if ten percent (10%) of the shares of Finisar Common
Stock to be delivered to any holder of InterSAN Common Stock is less than ten
(10) shares, such holder shall not be obligated to contribute shares of Finisar
Common Stock to the Escrow. The percentage of the Escrow Shares contributed on
behalf of each holder of InterSAN Preferred Stock contributing to the Escrow, as
shown in a schedule to be delivered at the Closing and attached to the Escrow
Agreement, shall be ten percent (10%) of the shares of Finisar Common Stock
entitled to be received by each such holder of InterSAN Preferred Stock at the
Effective Time; provided, however, that if ten percent (10%) of the shares of
Finisar Common Stock to be delivered to any holder of InterSAN Preferred Stock
is less than ten (10) shares, such holder shall not be obligated to contribute
shares of Finisar Common Stock to the Escrow.

          (b) The Escrow Shares shall be subject to claims of indemnification
under Article IX and the procedures specified in the Escrow Agreement. Subject
to the provisions of Section 9.2(d), the sole recourse for claims under this
Agreement shall be the Escrow Shares.

     Section 2.5 Dissenters’ Rights. In the event the Merger becomes effective
without the approval of the holders of 100% of the outstanding shares of
InterSAN Capital Stock, any shares of InterSAN Capital Stock held by
stockholders who properly exercise and perfect the appraisal rights set forth in
Section 262 of the DGCL (and, if InterSAN is subject to Section 2115 of the
California Corporations Code, such rights as may be granted to persons in
Chapter 13 of the California Corporations Code) (the “Dissenting Shares”) shall
not be converted pursuant to Section 2.2, but shall instead be converted into
the right to receive such consideration as may be determined to be due with
respect to such Dissenting Shares pursuant to the provisions of the applicable
law. Finisar shall have the right to control all negotiations and proceedings
with respect to the determination of the appropriate value of the InterSAN
Capital Stock pursuant to the applicable law. InterSAN agrees that, without the
prior written consent of Finisar or as required under the applicable law, it
will not voluntarily make any payment with respect to, or determine or offer to
determine, the value of the InterSAN Capital Stock. Each holder of Dissenting
Shares (a “Dissenting Shareholder”) who, pursuant to the provisions of the
applicable law, becomes entitled to payment of the value of InterSAN Capital
Stock, as determined pursuant to applicable law, shall receive payment therefor
(but only after the value therefor shall have been agreed upon or finally
determined pursuant to the provisions of the applicable law). In the event that
any holder of InterSAN Capital Stock fails to make an effective demand for
payment or otherwise loses his, her or its status as a Dissenting Shareholder,
Finisar shall, as of the later of the Effective Time or the occurrence of such
event, issue and deliver, upon surrender by such Dissenting Shareholder of his,
her or its Certificate(s), the shares of Finisar Common Stock and cash,
including any cash payment in lieu of fractional shares, in each case without

InterSAN and would not prevent or materially alter or delay any of the
transactions contemplated by this Agreement.

     Section 3.4 Financial Statements. InterSAN has delivered to Finisar its
audited financial statements, including statements of operations and cash flows,
for the year ended December 31, 2003, and its unaudited financial statements,
including statements of operations and cash flows, for the year ended
December 31, 2004 and a balance sheet as of December 31, 2004 (the “Balance
Sheet Date”) (collectively, the “InterSAN Financial Statements”). The InterSAN
Financial Statements were prepared in accordance with United States generally
accepted accounting principles (“GAAP”) applied on a consistent basis throughout
the periods involved and fairly present, in all material respects, the financial
position of InterSAN as of such dates, and its results of operations and cash
flows for such periods, except that, in the case of unaudited financial
statements, all notes to financial statements required under GAAP are not
included and such unaudited financial statements are subject to normal and
recurring year-end adjustments. InterSAN’s cash balance as of February 28, 2005
is set forth in Section 3.4 of the InterSAN Disclosure Schedule.

     Section 3.5 Absence of Undisclosed Liabilities. InterSAN does not have any
liabilities, either accrued or contingent (whether or not required to be
reflected in financial statements in accordance with GAAP), and whether due or
to become due, other than (i) liabilities reflected or provided for on the
balance sheet as of the Balance Sheet Date (the “InterSAN Balance Sheet”)
contained in the InterSAN Financial Statements, (ii) liabilities contemplated by
this Agreement or described in the InterSAN Disclosure Schedule, and
(iii) normal or recurring liabilities incurred since the Balance Sheet Date in
the ordinary course of business consistent with past practices.

     Section 3.6 Accounts Receivable. All accounts receivable of InterSAN
(including those accounts receivable shown on the InterSAN Balance Sheet that
have not yet been collected and those accounts receivable that have arisen since
the Balance Sheet Date and have not yet

11

--------------------------------------------------------------------------------

 

been collected) (i) represent valid obligations of customers of InterSAN arising
from bona fide transactions entered into in the ordinary course of business,
(ii) are current, and (iii) other than accounts receivable owed by Finisar, will
be collected in full. None of such accounts receivable is subject to any claim
of offset or recoupment or counterclaim, and InterSAN has no knowledge of any
specific facts that would be likely to give rise to any such claim. No amount of
such accounts receivable is contingent upon the performance by InterSAN of any
obligation and no agreement for deduction or discount has been made with respect
to any such accounts receivable.

     Section 3.7 Inventories. The inventories shown on the InterSAN Balance
Sheet or thereafter acquired by InterSAN consist of items of a quantity and
quality usable or salable in the ordinary course of business. Since the Balance
Sheet Date, InterSAN has continued to replenish inventories in a normal and
customary manner consistent with past practices. InterSAN has not received
written notice that it will experience in the foreseeable future any difficulty
in its ability to obtain (in the desired quantity and quality, and at prices and
on other terms and conditions of supply consistent with past availability), the
supplies or component products required for the manufacture, assembly or
production of its products. The value at which inventories are carried reflect
the inventory valuation policy of InterSAN, which is consistent with its past
practice and in accordance with GAAP. Due provision has been made on the books
of InterSAN, consistent with past practices, to provide for all slow-moving,
obsolete, or unusable inventories at their estimated useful or scrap values, and
such inventory reserves are adequate to provide for such slow-moving, obsolete
or unusable inventory and inventory shrinkage.

     Section 3.8 Absence of Certain Changes or Events. Since December 31, 2004,
InterSAN has conducted its business in the ordinary course and in a manner
consistent with past practices and, since such date, InterSAN has not:

Effect on InterSAN;

insurance or not, having a Material Adverse Effect on InterSAN;

Stock issued upon exercise of options under the InterSAN Option Plan outstanding

business;

          (n) agreed to take any action described in this Section 3.8; or

          (o) taken any other action that would have required the consent of

          (i) Neither InterSAN nor, to the knowledge of InterSAN, any of its
current or former officers, employees or consultants has any patents issued or
patent applications pending for any device, process, method, design or invention
of any kind now used or needed by InterSAN in the furtherance of its business
operations as currently being conducted or as currently proposed to be conducted
by InterSAN, which patents or applications have not been assigned to InterSAN
with such assignment duly recorded in the United States Patent Office or with
the applicable foreign Governmental Entity.

          (j) InterSAN has taken reasonable measures and precautions to protect
and maintain the confidentiality, secrecy and value of all InterSAN Intellectual
Property Rights (except InterSAN Intellectual Property Rights whose value would
not be impaired by disclosure). Without limiting the generality of the
foregoing, (i) all current and former employees of InterSAN who are or were
involved in, or who have contributed to, the creation or development of any
InterSAN Intellectual Property Rights have executed and delivered to InterSAN an
agreement (containing no exceptions to or exclusions from the scope of its
coverage) that is substantially identical to the form of confidential
information and invention assignment agreement previously delivered by InterSAN
to Finisar, and (ii) all current and former consultants and independent
contractors to InterSAN who are or were involved in, or who have contributed to,
the creation or development of any InterSAN Intellectual Property Rights have
executed and delivered to InterSAN an agreement (containing no exceptions to or
exclusions from the scope of its coverage) that is substantially identical to
the form of consultant confidential information and invention assignment
agreement previously delivered to Finisar. No current or former employee,
officer, director, stockholder, consultant or independent contractor has any
right, claim or interest in or with respect to any InterSAN Intellectual
Property Rights. Neither the execution or delivery of any such agreement by any
such person, nor the carrying on by any such person, as an employee, consultant
or independent contractor, of InterSAN’s business as currently conducted and as
currently proposed to be conducted, has or 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
obligated.

     Section 3.12 Bank Accounts. The InterSAN Disclosure Schedule sets forth the
names and locations of all banks and other financial institutions at which
InterSAN maintains accounts of any nature, the type of accounts maintained at

          (b) No party to any such contract, agreement or instrument has
notified InterSAN that it intends to cancel, withdraw, modify or amend such
contract, agreement or instrument.

          (c) InterSAN is not in default under or in breach or violation of, nor
is there any valid basis for any claim of default by InterSAN under, or breach
or violation by InterSAN of, any Material Contract. To InterSAN’s knowledge, no
other party is in default under or in breach or violation of, nor is there any
valid basis for any claim of default by any other party under, or breach or
violation by any other party of, any Material Contract. All of the Material
Contracts are in full force and effect and valid, binding and enforceable in
accordance with their respective terms, except as such enforceability may be
limited by (i) bankruptcy, insolvency, moratorium or other similar laws
affecting or relating to creditors’ rights generally, and (ii) general

labor practice and there is no unfair labor practice complaint against InterSAN
pending or, to InterSAN’s knowledge, threatened before any Governmental Entity.

InterSAN’s knowledge, threatened against InterSAN.

period. All of the prices charged by InterSAN in connection with the marketing

entity, discriminatory pricing, price fixing, unfair competition, false

to anti-competitive practices or unfair trade practices of any kind, and, to
InterSAN’s knowledge, no specific situation, set of facts or occurrence provides
any basis for any such claim.

the Securities Act of 1933, as amended (the “Securities Act”), and the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), as the case
may be, and (ii) did not at the time it was filed (or if amended or superseded
by a filing prior to the date of this Agreement, then on the date of such
filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated in such Finisar SEC Report or necessary in

27

--------------------------------------------------------------------------------

 

order to make the statements in such Finisar SEC Report, in the light of the
circumstances under which they were made, not misleading.

          (b) Each of the consolidated financial statements (including, in each
case, any related notes) contained in the Finisar SEC Reports, including any
Finisar SEC Reports filed after the date of this Agreement until the Closing,
complied or will comply as to form in all material respects with the applicable
published rules and regulations of the SEC with respect thereto, was or will be
prepared in accordance with GAAP applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited statements, as permitted by Form 10-Q
promulgated by the SEC) and presented fairly or will present fairly, in all
material respects, the consolidated financial position of Finisar and its
Subsidiaries as of the respective dates, and the consolidated results of its
operations and cash flows for the periods indicated, except that the unaudited
interim financial statements were or are subject to normal and recurring
year-end adjustments which were not or are not expected to be material in
amount. The unaudited consolidated balance sheet of Finisar as of October 31,
2004 is referred to herein as the “Finisar Balance Sheet.”

     Section 4.5 Absence of Undisclosed Liabilities. Finisar and its
Subsidiaries do not have any liabilities, either accrued or contingent (whether
or not required to be reflected in financial statements in accordance with
GAAP), and whether due or to become due, which individually or in the aggregate
would be reasonably likely to have a Material Adverse Effect on Finisar, other
than (i) liabilities reflected or provided for on the Finisar Balance Sheet,
(ii) liabilities specifically contemplated by this Agreement, or described in
the Finisar Disclosure Schedule or Finisar SEC Reports, and (iii) normal or
recurring liabilities incurred since October 31, 2004 in the ordinary course of
business consistent with past practices.

     Section 4.6 Litigation. Except as described in the Finisar SEC Reports,
there is no action, suit or proceeding, claim, arbitration or investigation
against Finisar pending or as to which Finisar has received any written notice
of assertion, which is reasonably likely to have a Material Adverse Effect on
Finisar or a material adverse effect on the ability of Finisar to consummate the
transactions contemplated by this Agreement.

     Section 4.7 Tax Reorganization. As of the date hereof, Finisar has not
taken or agreed to take any action, and does not have knowledge of any fact or
circumstance, that would prevent the Merger from qualifying as a reorganization
within the meaning of Section 368(a) of the Code.

     Section 4.8 Stockholder Approval. The approval of the stockholders of
Finisar is not required for the execution and delivery of this Agreement and the
other Transaction Documents to which Finisar or Sub is or will be a party or the
consummation of the transactions contemplated hereby and thereby.

     Section 4.9 Absence of Certain Changes. Since October 31, 2004 through the
date hereof, except as disclosed in the Finisar SEC Reports there has not been a
Material Adverse Effect on the business or operations of Finisar. Without
limiting the foregoing, during such

28

--------------------------------------------------------------------------------

 

period, except as disclosed in the Finisar SEC Reports or as contemplated by
this Agreement, there has not been:

          (a) any declaration, setting aside or payment of any dividend or other
distribution with respect to any outstanding shares of capital stock or other
equity securities of, or other ownership interests in, Finisar;

          (b) any amendment to any provision of the Certificate of Incorporation
or Bylaws of Finisar, or of any material term of any outstanding security issued
by Finisar; or

          (c) any authorization of, or commitment or agreement to take any of,
the foregoing actions, except as otherwise permitted by this Agreement.

     Section 4.10 Rule 144. Finisar satisfies all of the issuer requirements
under Rule 144(c) of the Securities Act and has taken such actions as would be
required to enable a holder of InterSAN Capital Stock to sell the shares of
Finisar Common Stock issued in the Merger under Rule 145(d) of the Securities
Act.

     Section 4.11 No Misrepresentation. No representation or warranty by Finisar
or Sub in this Agreement, or any exhibit or schedule hereto, or any certificate
or instrument furnished or to be furnished by or on behalf of Finisar or Sub
pursuant to this Agreement, when taken together, contains or shall contain any
untrue statement of a material fact.

shall first endeavor to satisfy such current obligations with the proceeds from
payments made by Finisar under purchase orders or other contracts with InterSAN

ADDITIONAL AGREEMENTS

     Section 6.1 No Solicitation.

          (a) During the period from the date of this Agreement until the
earlier of the Effective Time or the termination of this Agreement pursuant to
Article VIII of this Agreement, InterSAN shall not, directly or indirectly,
through any officer, director, employee, representative or agent (each a
“Representative”), (i) enter into any agreement, understanding or arrangement
relating to any Acquisition Proposal (as defined below) with any party other
than Finisar, (ii) solicit, initiate, induce or entertain offers from, negotiate
with or in any manner encourage, discuss, accept, or consider, any Acquisition
Proposal from any party other than Finisar, (iii) provide any nonpublic
information regarding InterSAN or its business or operations to any party (other
than to representatives of Finisar) in connection with, in response to or in
anticipation of an Acquisition Proposal or an inquiry or indication of interest
that could reasonably be expected to lead to an Acquisition Proposal, or
(iv) permit any Representative or affiliate of InterSAN to do any of the
foregoing (other than to representatives of Finisar). The term “Acquisition
Proposal,” as used in this Agreement, refers to any proposal, plan, agreement,
understanding or arrangement contemplating (i) any tender offer, merger,
consolidation, business combination, reorganization, recapitalization or similar
transaction involving InterSAN or any of its affiliates, (ii) any transfer or
issuance of ten percent (10%) or more of the capital stock or other securities
of InterSAN or any of its affiliates, (iii) any transfer or license of any
material assets of InterSAN or any of its affiliates (other than sales in the
ordinary course of business), or (iv) any similar transaction that would be
reasonably likely to have a Material Adverse Effect upon any of the transactions
contemplated by this Agreement.

          (b) InterSAN shall promptly (and in no event later than twenty-four
(24) hours after receipt by InterSAN or its Representatives of any Acquisition
Proposal or any request for nonpublic information in connection with an
Acquisition Proposal or for access to the properties, books or records of
InterSAN by any person or entity that informs InterSAN that it is considering
making, or has made, an Acquisition Proposal) notify Finisar of such Acquisition
Proposal or request for such information or for access to InterSAN’s properties,
books or records. Such notice shall be made orally and in writing and shall
indicate in reasonable detail the identity of the offeror and the terms and
conditions of such proposal, inquiry or contact, subject to the terms of any
confidentiality agreement in effect as of the date of this Agreement. InterSAN
shall keep Finisar informed with respect to any material changes in the status
of any such Acquisition Proposal, inquiry, indication of interest or request and
any modification or proposed modification thereto.

     Section 6.2 Consents. Each of Finisar and InterSAN shall use all reasonable
efforts to obtain all necessary consents, waivers and approvals under any of
Finisar’s or InterSAN’s material agreements, contracts, licenses or leases as
may be necessary or advisable to consummate the Merger and the other
transactions contemplated by this Agreement.

     Section 6.3 Access to Information. Upon reasonable notice, InterSAN shall
afford to the officers, employees, accountants, counsel and other
representatives of Finisar, reasonable

32

--------------------------------------------------------------------------------

 

access, during normal business hours during the period prior to the Effective
Time, to all its properties, books, contracts, commitments and records and,
during such period, InterSAN shall promptly furnish or make available to Finisar
or its representatives all other information concerning its business, properties
and personnel as such other party may reasonably request. Unless otherwise
required by law, the parties will treat any such information which is nonpublic
in confidence in accordance with the Mutual Nondisclosure Agreement dated
October 3, 2004 (the “Confidentiality Agreement”) between Finisar and InterSAN,
which Confidentiality Agreement shall continue in full force and effect in
accordance with its terms. No information or knowledge obtained in any
investigation pursuant to this Section 6.3 shall affect or be deemed to modify
any representation or warranty contained in this Agreement or the conditions to
the obligations of the parties to consummate the Merger.

     Section 6.4 Legal Conditions to Merger. Each of Finisar and InterSAN will
take all reasonable actions necessary to comply promptly with all legal
requirements which may be imposed on itself with respect to the Merger (which
actions shall include, without limitation, furnishing all information reasonably
necessary in connection with approvals of or filings with any Governmental
Entity) and will promptly cooperate with and furnish information to each other
in connection with any such requirements imposed upon either of them or any of
their Subsidiaries in connection with the Merger. Each of Finisar and InterSAN
will take all reasonable actions necessary to obtain (and will cooperate with
each other in obtaining) any consent, authorization, order or approval of, or
any exemption by, any Governmental Entity required to be obtained or made by
InterSAN, Finisar or any of their Subsidiaries in connection with the Merger or
the taking of any action contemplated thereby or by this Agreement and to enable
the Closing to occur as promptly as practicable.

     Section 6.5 Public Disclosure. Finisar and InterSAN shall consult with each
other before issuing any press release or otherwise making any public statement
with respect to the Merger or this Agreement and neither party shall issue any
such press release or make any such public statement prior to receiving written
consent to such press release or public statement from the other party, except
as may be required by law or by the rules or regulations of the SEC or the NNM.

     Section 6.6 Tax-Free Reorganization. Finisar and InterSAN each intend that
the Merger shall qualify for treatment as a reorganization within the meaning of
Section 368(a) of the Code. Finisar and InterSAN each agree to refrain from
taking any action prior to, on or after the Effective Time that would cause the
Merger to fail to qualify as a reorganization within the meaning of Section
368(a) of the Code. Finisar and InterSAN agree to report the Merger as a
reorganization on all Tax Returns.

     Section 6.7 Nasdaq Quotation. Finisar agrees to continue the quotation of
Finisar Common Stock on the NNM during the term of this Agreement. Finisar shall
take all actions within its power and use its best efforts to cause the shares
of Finisar Common Stock to be issued in connection with the Merger to be
approved for quotation on the NNM, subject to official notice of issuance, prior
to the Closing Date.

33

--------------------------------------------------------------------------------

 

     Section 6.8 Securities Law Matters.

          (a) Unless Finisar elects to file a Registration Statement pursuant to
Section 6.8(g) below, as soon as practicable following the execution of this
Agreement, Finisar, with the cooperation of InterSAN, will file a request for a
hearing (the “Hearing”) before the Commissioner of Corporations of the State of
California (the “California Commissioner”) to consider the terms, conditions and
fairness of the transactions contemplated by this Agreement pursuant to
Section 25142 of the California Corporations Code, together with an application
for a permit relating to the transactions contemplated by this Agreement and the
Certificate of Merger (the “Permit”). Finisar shall take all actions reasonably
required to complete the request for Hearing, the application for Permit and
such other notices and documents as may be reasonably required in connection
with the Hearing and the application for Permit. InterSAN shall promptly furnish
to Finisar all data and information relating to InterSAN as Finisar shall
reasonably determine to be necessary in connection with such request and
application and such other notices and documents as may be required in
connection with the Hearing and application for Permit. Finisar and InterSAN
shall use their respective best efforts to cause the Hearing to take place and
the Permit to be issued at the earliest practicable date.

          (b) Finisar shall prepare and file with appropriate state securities
or “Blue Sky” authorities all applications for qualification or approval (or
notices required to perfect exemptions from such compliance) as may be required
in connection with the Merger. InterSAN shall use all reasonable efforts to
assist Finisar as may be necessary to comply with all appropriate state
securities or Blue Sky laws which may be applicable in connection with the
Merger.

          (c) In connection with the Hearing, InterSAN shall prepare, with the
cooperation of Finisar, a disclosure document (the “Consent Solicitation
Statement”) describing this Agreement and the transactions contemplated hereby
for the purpose of soliciting the approval of InterSAN stockholders. Finisar
shall provide such information about itself as InterSAN shall reasonably
request. The information supplied by InterSAN for inclusion in the Consent
Solicitation Statement shall not, on the date the Consent Solicitation Statement
is first mailed to InterSAN Stockholders, nor at the Effective Time, contain any
statement which, at such time, is false or misleading with respect to any
material fact, or omit to state any material fact necessary in order to make the
statements made therein, in light of the circumstances under which they are
made, not false or misleading, or omit to state any material fact necessary to
correct any statement in any earlier communication which has become false or
misleading. Notwithstanding the foregoing, InterSAN makes no representation,
warranty or covenant with respect to any information supplied by Finisar or Sub
which is contained in any of the foregoing documents. The information supplied
by Finisar for inclusion in the Consent Solicitation Statement shall not, on the
date the Consent Solicitation Statement is first mailed to InterSAN’s
stockholders, nor at the Effective Time, contain any statement which, at such
time, is false or misleading with respect to any material fact, or omit to state
any material fact necessary in order to make the statements made therein, in
light of the circumstances under which they are made, not false or misleading;
or omit to state any material fact necessary to correct any statement in any
earlier communication which has become false or misleading. Notwithstanding the
foregoing, Finisar and Sub make no representation, warranty or covenant with
respect to any information supplied by InterSAN which is contained in any of the
foregoing documents.

34

--------------------------------------------------------------------------------

 

          (d) The Consent Solicitation Statement shall constitute a disclosure
document for the offer and issuance of shares of Finisar Common Stock to be
received by the holders of InterSAN Capital Stock in the Merger. Finisar and
InterSAN shall each use reasonable efforts to cause the Consent Solicitation
Statement to comply with applicable federal and state securities laws
requirements. Each of Finisar and InterSAN agrees to provide promptly to the
other such information concerning its business and financial statements and
affairs as, in the reasonable judgment of the providing party or its counsel,
may be required or appropriate for inclusion in the Consent Solicitation
Statement or in any amendments or supplements thereto, and to cause its counsel
and auditors, if applicable, to cooperate with the other’s counsel and auditors,
if applicable, in the preparation of the Consent Solicitation Statement.
InterSAN will promptly advise Finisar, and Finisar will promptly advise
InterSAN, in writing if at any time prior to the Effective Time either InterSAN
or Finisar shall obtain knowledge of any facts that might make it necessary or
appropriate to amend or supplement the Consent Solicitation Statement in order
to make the statements contained or incorporated by reference therein not
misleading or to comply with applicable law. The Consent Solicitation Statement
shall contain the unanimous recommendation of the Board of Directors of InterSAN
that the stockholders of InterSAN approve the Merger and this Agreement and the
unanimous conclusion of the Board of Directors that the terms and conditions of
the Merger are fair and reasonable to the stockholders of InterSAN. Anything to
the contrary contained herein notwithstanding, InterSAN shall not include in the
Consent Solicitation Statement any information with respect to Finisar or its
affiliates or associates, the form and content of which information shall not
have been approved by Finisar prior to such inclusion.

          (e) Upon receipt of the Permit, InterSAN shall, as promptly as
possible but not later than three (3) days following the effectiveness of the
Permit, submit this Agreement and the transactions contemplated hereby to the
stockholders of InterSAN for approval and adoption as provided by the DGCL and
its Certificate of Incorporation and Bylaws. InterSAN shall use all reasonable
efforts to solicit and obtain the consent of the InterSAN stockholders
sufficient to approve the Merger and this Agreement and to enable the Closing to
occur as promptly as practicable. InterSAN shall ensure that the meeting of the
stockholders of InterSAN called for the purpose of approving the Merger and this
Agreement, or the solicitation of written consents of the stockholders of
InterSAN without a meeting, is conducted, and that all proxies solicited by
InterSAN in connection with any such meeting are solicited, in compliance with
applicable law and the InterSAN charter documents. Subject to the provisions of
Section 8.1(e) of this Agreement, InterSAN’s obligation to call, give notice of,
convene and hold the stockholders’ meeting, or to solicit the written consent of
its stockholders without a meeting, in accordance with this Section 6.8(e) shall
not be limited to or otherwise affected by the commencement, disclosure,
announcement or submission to InterSAN of any Acquisition Proposal.

          (f) Schedule 6.8(f) sets forth those persons who, in InterSAN’s
reasonable judgment are or may be “affiliates” of InterSAN within the meaning of
Rule 145 promulgated under the Securities Act (each such person a “InterSAN
Affiliate”). InterSAN shall provide Finisar such information and documents as
Finisar shall reasonably request in connection with Finisar’s review of such
list. InterSAN shall use all reasonable efforts to deliver or cause to be
delivered to Finisar, promptly following the execution of this Agreement (and in
any case prior to the Closing), from each of the InterSAN Affiliates an executed
Affiliate Agreement in the form attached hereto as Exhibit C. Finisar shall be
entitled to place appropriate legends on the

35

--------------------------------------------------------------------------------

 

certificates evidencing any Finisar Common Stock to be received by such InterSAN
Affiliates pursuant to the terms of this Agreement, and to issue appropriate
stop transfer instructions to the transfer agent for Finisar Common Stock,
consistent with the terms of such Affiliate Agreements.

          (g) If Finisar and InterSAN mutually agree, or in the event that the
California Commissioner notifies Finisar or InterSAN of the California
Commissioner’s determination not to grant the Hearing, not to permit the mailing
of the Hearing Notice and/or not to issue the Permit (or that any of the
foregoing will be conditioned upon a material alteration to the terms of this
Agreement, any exhibit or schedule hereto or the transactions contemplated
hereby or thereby) (such date on which Finisar and InterSAN receive such
notification, the “Notification Date”), then, Finisar shall use commercially
reasonable efforts to cause the shares of Finisar Common Stock issued in the
Merger (collectively, the “Registrable Securities”) to be registered under the
Securities Act so as to permit the resale thereof, and in connection therewith
shall use its best efforts to prepare and file with the SEC within fifteen
(15) days following the Closing Date, and shall use commercially reasonable
efforts to cause to become effective no later than sixty (60) days thereafter, a
registration statement (the “Registration Statement”) on Form S-3 or on such
successor form as is then available under the Securities Act covering the
Registrable Securities; provided, however, that each holder of Registrable
Securities (“Holder”) shall provide all such information and materials to
Finisar and take all such action as may be required in order to permit Finisar
to comply with all applicable requirements of the SEC and to obtain any desired
acceleration of the effective date of such Registration Statement. Such
provision of information and materials is a condition precedent to the
obligations of Finisar pursuant to this Section 6.8(g). Finisar shall not be
required to effect more than one (1) registration under this Section 6.8(g). The
offering made pursuant to such registration shall not be underwritten.
Notwithstanding the foregoing, Finisar shall be entitled to postpone the filing
or declaration of effectiveness of the Registration Statement for a reasonable
period of time not to exceed thirty (30) calendar days after the deadlines
therefore set forth in this Section 6.8(g), if Finisar determines that there
exists material nonpublic information about Finisar which would be required by
the Securities Act to be disclosed in the Registration Statement, the disclosure
of which, in the good faith determination of the Board of Directors of Finisar,
would be detrimental to Finisar.

               Subject to the limitations of this Section 6.8(g), Finisar shall:
(i) prepare and file the Registration Statement with the SEC in accordance with
this Section 6.8(g) with respect to the Registrable Securities and shall take
all actions within its power or control to cause the Registration Statement to
become effective as promptly as practicable after filing and to keep the
Registration Statement effective until twelve (12) months after the Effective
Time; (ii) prepare and file with the SEC such amendments and supplements to the
Registration Statement and the prospectus used in connection therewith as may be
necessary, and to comply with the provisions of the Securities Act with respect
to the sale or other disposition of all securities proposed to be registered in
the Registration Statement during the period specified in clause (i) above; and
(iii) furnish to each Holder such number of copies of any prospectus (including
any preliminary prospectus and any amended or supplemented prospectus) in
conformity with the requirements of the Securities Act, and such other
documents, as each Holder may reasonably request in order to effect the offering
and sale of the Registrable Securities to be offered and sold.

36

--------------------------------------------------------------------------------

 

               Notwithstanding any other provision of this Section 6.8(g),
Finisar shall have the right at any time to require that all Holders suspend
further open market offers and sales of Registrable Securities pursuant to the
Registration Statement whenever, and for so long as, in the reasonable judgment
of Finisar in good faith after consultation with counsel, there is or may be in
existence material undisclosed information or events with respect to Finisar
(the “Suspension Right”). In the event Finisar exercises the Suspension Right,
such suspension will continue for the period of time reasonably necessary for
disclosure to occur at a time that is not materially detrimental to Finisar and
its stockholders or until such time as the information or event is no longer
material, each as determined in good faith by Finisar after consultation with
counsel. Finisar will use all reasonable efforts to limit the length of the
suspension to thirty (30) calendar days or less. Finisar agrees to notify the
Holders promptly upon termination of the suspension. Notwithstanding any other
provision of this Section 6.8(g), in no event shall the Suspension Right be
exercised (i) more than two (2) times in any 12-month period or (ii) for a total
of more than ninety (90) days in any 12-month period.

               Finisar will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act against all expenses, claims,
losses, damages or liabilities (or actions in respect thereof), including any of
the foregoing incurred in settlement of any litigation, commenced or threatened,
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any registration statement, prospectus, preliminary
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any registration, qualification or compliance effected
pursuant to this Section 6.8, 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, in light of the circumstances in which they were made,
not misleading, or any violation or any alleged violation by Finisar of any rule
or regulation promulgated under the Securities Act or the Exchange Act in
connection with any such registration, qualification or compliance, and Finisar
will reimburse each such Holder, each of its officers and directors, 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, as such expenses are incurred,
provided that Finisar 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 Finisar by
such Holder or controlling person and specifically for use therein.

               It shall be a condition to Finisar’s obligations hereunder to
register the Registrable Securities of any Holder that such Holder agrees to
indemnify Finisar, each of Finisar’s directors and officers, each person who
controls Finisar 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
Finisar, such other Holders,

37

--------------------------------------------------------------------------------

 

directors, officers, persons 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, as such expenses are incurred, 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 about such Holder or
such Holder’s plans for distributing the Registrable Securities furnished to
Finisar by such Holder specifically for use therein.

               Each party entitled to indemnification under this Section 6.8(g)
(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 unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party’s expense; provided, however, that an Indemnified Party (together with all
other Indemnified Parties which 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 differing or potentially differing interests between such
Indemnified Party and any other party represented by such counsel in such
proceeding. The failure of any Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under this
Section 6.8(g) unless the failure to give such notice is materially prejudicial
to an Indemnifying Party’s ability to defend such action. 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.

               If the average of the closing prices per share of the Finisar
Common Stock on the NNM over the five (5) day period ending one (1) day prior to
the date on which the Registration Statement is declared effective (the “S-3
Share Price”) is less than the Finisar Share Price, Finisar shall deliver to
each holder of Registrable Securities a whole number of shares of Finisar Common
Stock (rounded to the nearest whole share) equal to the difference between
(i) the number of shares of Registrable Securities issued to such holder at the
Effective Time divided by the quotient of the S-3 Share Price and the Finisar
Share Price less (ii) the number of shares of Registrable Securities issued to
such holder at the Effective Time.

     Section 6.9 Employment Matters.

          (a) Effective on the Closing Date, Chris Melville and Christina
Mercier (the “Key Employees”) will become employees of the Surviving Corporation
pursuant to the terms of Employment Agreements in the form of Exhibit D-1 and
Exhibit D-2 hereto, respectively (the “Employment Agreements”).

38

--------------------------------------------------------------------------------

 

          (b) Prior to the Closing Date, Finisar will make offers of “at will”
employment (on behalf of the Surviving Corporation) to all employees of InterSAN
recommended by the Chief Executive Officer of InterSAN and set forth on
Schedule 6.9(b) hereto, such offers to be conditioned upon the consummation of
the Merger. The employment of all InterSAN employees whose employment will not
be continued by the Surviving Corporation will be terminated by InterSAN prior
to the Closing Date.

          (c) Prior to the Closing Date, all InterSAN employees who continue as
employees of Finisar or InterSAN following the Effective Time (the “Continuing
Employees”) shall have executed Finisar’s standard form of confidential
information and invention assignment agreement.

          (d) Finisar agrees to maintain offices at InterSAN’s existing
facility, or an equivalent facility, in Scotts Valley, California for the
Continuing Employees for at least twelve (12) months following the Closing Date.

          (e) Finisar agrees to provide Continuing Employees who are terminated
for reasons other than cause prior to the six (6) month anniversary of the
Closing Date with their then current base salaries as set forth in the list
provided to Finisar and with equivalent employee benefits as described in
Section 6.10 below. For purposes of this Section 6.9(e), “Cause” means a
Continuing Employee’s (i) theft, dishonesty or falsification of any documents or
records of InterSAN, Finisar, the Surviving Corporation or any of their
respective affiliates; (ii) breach of the employee confidential information and
invention assignment agreement of InterSAN, Finisar, the Surviving Corporation
or any of their respective affiliates; (iii) willful failure to perform any
reasonably assigned duties after written notice from InterSAN, Finisar, the
Surviving Corporation or any of their respective affiliates of, and a reasonable
opportunity (not to exceed 30 days) to cure, such willful failure;
(iv) conviction (including any plea of guilty or nolo contendere) of any felony
or other crime(s) involving moral turpitude; or (v) repeated willful failure to
abide by the workplace conduct guidelines and employee policies of InterSAN,
Finisar, the Surviving Corporation or any of their respective affiliates
following written notification of such willful failure.

          (f) Finisar agrees that Continuing Employees other than the Key
Employees will retain their current titles as set forth in the list provided to
Finisar and the current reporting structure following the Closing Date;
provided, however, that Finisar shall have the right in its sole discretion to
change such titles and reporting structure as necessary to implement changes in
Finisar’s plans and strategies for the Surviving Corporation and Finisar
following the Closing Date.

          (g) Finisar agrees to maintain the base salaries of Continuing
Employees at no less than the current levels set forth in the list provided to
Finisar, and in all events at the level of compensation provided to Finisar
employees holding comparable positions, until the earlier of their termination
of employment or a performance review in the summer of 2006.

     Section 6.10 Employee Benefits. All Continuing Employees shall be eligible
to participate in those benefit plans and programs (the “Finisar Plans”) that
are available to other Finisar employees holding comparable positions. To the
extent permitted by the Finisar Plans or

39

--------------------------------------------------------------------------------

 

as required by law, each Continuing Employee shall be given credit, for purposes
of any service requirements for participation or vesting, for his or her period
of continuous service with InterSAN prior to the Effective Time.

immediately preceding the Effective Time, InterSAN shall terminate any and all
InterSAN Employee Plans that are subject to the requirements of Code Section
401(k) (collectively, the “401(k) Plan”) unless Finisar notifies InterSAN, in
writing, no later than five (5) days prior to the Effective Time that such
termination is not required. Prior to the Effective Time, InterSAN shall provide
to Finisar (i) executed resolutions by InterSAN’s Board of Directors authorizing
the termination of the 401(k) Plan and (ii) an executed amendment to the 401(k)
Plan sufficient to assure compliance with all applicable requirements of the
Code and regulations thereunder so that the tax-qualified status of the 401(k)
Plan shall be maintained at the time of termination. The form and substance of
such resolutions and amendment shall be subject to the prior review and approval
of Finisar.

     Section 6.12 Brokers or Finders. Each of Finisar and InterSAN represents,
as to itself, its Subsidiaries and its Affiliates, that no agent, broker,
investment banker, financial advisor or other firm or person is or will be
entitled to any broker’s or finder’s fee or any other commission or similar fee
in connection with any of the transactions contemplated by this Agreement,
except White Dove Partners (“White Dove”), financial advisor to Finisar. Except
for the fees and expenses of White Dove which are to be paid by Finisar, each of
Finisar and InterSAN agrees to indemnify and hold the other harmless from and
against any and all liability for any broker’s or finder’s fee or any other
commission or similar fee in connection with any of the transactions
contemplated by this Agreement.

     Section 6.13 Additional Agreements; Reasonable Efforts. Subject to the
terms and conditions of this Agreement, each of the parties agrees to use all
reasonable efforts to take, or cause to be taken, all action and to do, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
this Agreement, including cooperating fully with the other party, including by
provision of information. Without limiting the generality of the foregoing,
(a) InterSAN will provide to Finisar all financial and accounting records that
shall be reasonably requested by Finisar for the purpose of preparing financial
statements of InterSAN for any period, or as of any date, prior to the Effective
Time to the extent such financial statements are required by GAAP or the
applicable rules and regulations of the SEC and (b) Finisar will take such
actions as may be necessary to provide InterSAN stockholders with the Merger
Consideration which they are entitled to receive hereunder within two
(2) business days after receipt of the documents to be delivered by the InterSAN
stockholders specified in Section 2.3(b) and will disclose information
concerning the Merger to the public, if required by the rules or regulations of
the SEC, within two (2) business days after the Effective Time. In case at any
time after the Effective Time any further action is necessary or desirable to
carry out the purposes of this Agreement or to vest the Surviving Corporation
with full title to all properties, assets, rights, approvals, immunities and
franchises of either of the Constituent Corporations, the proper officers and
directors of each party to this Agreement shall take all such necessary action.

40

--------------------------------------------------------------------------------

 

     Section 6.14 Expenses. The parties shall each pay their own legal,
accounting, financial advisory and consulting fees and other out-of-pocket
expenses related to the negotiation, preparation and carrying out of this
Agreement and the transactions herein contemplated. In the event the Merger is
consummated, all legal, accounting, financial advisory and consulting fees and
expenses incurred by InterSAN (whether paid or accrued) relating to the
negotiation, preparation and carrying out of this Agreement and the transactions
contemplated hereby, and obtaining all authorizations, consents, orders or
approvals of, or declarations or filings with, all Governmental Entities in
connection with such transactions (the “InterSAN Transaction Expenses”) shall be
paid by the Surviving Corporation; provided, however, that any InterSAN
Transaction Expenses in excess of $50,000 shall be borne by the former security
holders of InterSAN, as hereinafter provided. InterSAN shall provide a schedule
of estimated InterSAN Transaction Expenses not later than two (2) business days
prior to the Closing (the “Closing InterSAN Transaction Expense Schedule”). In
the event that the Closing InterSAN Transaction Expense Schedule sets forth
InterSAN Transaction Expenses in excess of $50,000 (“Excess InterSAN Transaction
Expenses”), the Merger Consideration shall be reduced as set forth in
Section 2.1(n). In the event that the Merger Consideration was not reduced by
the full amount of Excess InterSAN Transaction Expenses pursuant to
Section 2.1(n) or if any Excess InterSAN Transaction Expenses are identified
after the Effective Time, Finisar shall be entitled to assert a claim against
the Escrow Shares pursuant to Article IX hereof in order to recover all such
Excess InterSAN Transaction Expenses.

     Section 6.15 Amendment to InterSAN’s Certificate of Incorporation. InterSAN
shall use all reasonable efforts to obtain the approval by its stockholders of
an amendment to its Certificate of Incorporation to provide that the liquidation
preferences set forth in Article IV, Section 2 therein shall not apply to the
Merger and that the allocation of the Merger Consideration shall be as set forth
in this Agreement.

     Section 6.16 Waiver Agreements by Disqualified Individuals. Prior to the
Effective Time and, in any event, prior to the earliest time following the date
of this Agreement at which any payment or benefit which would constitute an
“excess parachute payment” within the meaning of Section 280G of the Code as a
consequence of any transaction or event contemplated by this Agreement (each
such payment or benefit being hereinafter referred to as a “Potential Excess
Parachute Payment”) in the absence of satisfaction of the shareholder approval
requirements described in Section 280G(b)(5) of the Code (the “Shareholder
Approval Requirements”) is paid or provided to or for the benefit of any person
who, with respect to InterSAN, is a “disqualified individual” within the meaning
of Section 280G(c) of the Code, InterSAN shall require such person to agree in
writing, in a form reasonably acceptable to Finisar (a “Waiver Agreement”), to
forfeit such person’s right to receive each and every Potential Excess Parachute
Payment unless, subsequent to the date of such Waiver Agreement, the
stockholders of InterSAN approve such Potential Excess Parachute Payment in
compliance with the Shareholder Approval Requirements.

and liabilities of the parties hereunder with respect to the portions of such
Third Party Claims that are covered by the indemnification provisions in this
Article IX (but excluding all other portions of such Third Party Claims and all
counterclaims and the like by the Indemnitee or its affiliates) shall be subject
to the following terms and conditions:

          (a) Indemnitee shall give the Stockholders’ Representative and the
Escrow Agent written notice of any such Third Party Claim promptly after receipt
by Indemnitee of notice thereof, and the Stockholders’ Representative may
undertake control of the defense thereof by counsel of its own choosing, which
counsel shall be reasonably acceptable to the Indemnitee. In such event,
Indemnitee may participate in the defense through its own counsel at its own
expense. If, however, the Stockholders’ Representative fails or refuses to
undertake the defense of such Third Party Claim within twenty (20) days after
written notice of such claim has

47

--------------------------------------------------------------------------------

 

been delivered to the Stockholders’ Representative by Indemnitee, Indemnitee
shall have the right to undertake the defense, compromise and, subject to
Section 9.5, settlement of such Third Party Claim with counsel of its own
choosing. Failure of Indemnitee to furnish written notice to the Stockholders’
Representative or the Escrow Agent of a Third Party Claim shall not release the
InterSAN Stockholders from their obligations hereunder, except to the extent
they are prejudiced by such failure.

          (b) Indemnitee and the Stockholders’ Representative shall cooperate
with each other in all reasonable respects in connection with the defense of any
Third Party Claim, including making available records relating to such claim and
furnishing employees of Indemnitee as may be reasonably necessary for the
preparation of the defense of any such Third Party Claim or for testimony as
witness in any proceeding relating to such claim.

          (c) Unless the Stockholders’ Representative has failed to fulfill its
obligations under this Article IX, no settlement by Indemnitee of a Third Party
Claim shall be made without the prior written consent by or on behalf of the
Stockholders’ Representative, which consent shall not be unreasonably withheld
or delayed. If the Stockholders’ Representative has assumed the defense of a
Third Party Claim as contemplated by this Section 9.4, no settlement of such
Third Party Claim may be made by the Stockholders’ Representative without the
prior written consent by or on behalf of Indemnitee, which consent shall not be
unreasonably withheld or delayed.

     Section 9.5 Manner of Indemnification.

          (a) The Escrow Shares deposited into Escrow pursuant to the Escrow
Agreement in accordance with the provisions of Section 2.5 shall provide a fund
against which members of the Finisar Group may assert claims of indemnification
under this Article IX. Except as specifically provided in Section 9.2(d), the
sole recourse of any member of the Finisar Group for claims with respect to this
Agreement or the transactions contemplated by this Agreement is to the Escrow
Shares.

          (b) Each claim asserted against the InterSAN Stockholders pursuant to
this Article IX shall be made only in accordance with the procedures set forth
herein and in the Escrow Agreement, subject to the provisions of Section 9.2(d)
hereof.

     Section 9.6 Appointment of Stockholders’ Representative. For purposes of
this Agreement, the InterSAN Stockholders hereby consent to the appointment of
Ned Carlson as the representative and attorney-in-fact for and on behalf of the
InterSAN Stockholders (the “Stockholders’ Representative”), and to the taking by
the Stockholders’ Representative of any and all actions and the making of any
decisions required or permitted to be taken by him under this Agreement or the
Escrow Agreement, including, without limitation, the exercise of the power to
(i) execute the Escrow Agreement on behalf of the InterSAN Stockholders,
(ii) authorize delivery to Finisar of Escrow Shares in satisfaction of
Indemnification Claims, (iii) agree to, negotiate, enter into settlements and
compromises of and comply with orders of courts and awards of arbitrators with
respect to such Indemnification Claims, (iv) resolve any Indemnification Claims
and (v) take all actions necessary in the judgment of the Stockholders’
Representative for the accomplishment of the foregoing and all of the other
terms, conditions and

48

--------------------------------------------------------------------------------

 

limitations of this Agreement and the Escrow Agreement. Accordingly, the
Stockholders’ Representative has unlimited authority and power to act on behalf
of each InterSAN Shareholder with respect to the Escrow Agreement and the
disposition, settlement or other handling of all Indemnification Claims. Each
InterSAN Stockholder will be bound by all actions taken by the Stockholders’
Representative in connection with all Indemnification Claims, and Finisar shall
be entitled to rely on any action or decision of the Stockholders’
Representative or taken by any person that Finisar reasonably believes to be
authorized to act on behalf of the Stockholders’ Representative. The
Stockholders’ Representative will incur no liability with respect to any action
taken or suffered by it in reliance upon any notice, direction, instruction,
consent, statement or other document believed by it to be genuine and to have
been signed by the proper person (and shall have no responsibility to determine
the authenticity thereof), nor for any other action or inaction, except his own
willful misconduct or bad faith. In all questions arising under this Agreement
or the Escrow Agreement, the Stockholders’ Representative may rely on the advice
of counsel, and the Stockholders’ Representative will not be liable to anyone
for anything done, omitted or suffered in good faith by the Stockholders’
Representative based on such advice. Except as expressly provided herein, the
Stockholders’ Representative will not be required to take any action involving
any expense unless the payment of such expense is made or provided for in a
manner satisfactory to him. The expenses of the Stockholders’ Representative
shall be paid from the Escrow Shares to the extent any Escrow Shares are
available after payment of all Finisar Losses under this Article IX. At any time
during the term of the Escrow Agreement, holders of a majority of the Escrow
Shares then held in Escrow may, by written consent, appoint a new representative
as the Stockholders’ Representative by sending notice and a copy of the written
consent appointing such new representative signed by holders of a majority of
the Escrow Shares to Finisar and the Escrow Agent. Such appointment will be
effective upon the later of the date indicated in the consent or the date such
consent is received by Finisar and the Escrow Agent. The Stockholders’
Representative may resign at any time. Upon the resignation of the Stockholders’
Representative, a successor, who shall be bound by all of the terms of this
Section 9.6, shall be named pursuant to Section 11 of the Escrow Agreement.

indicated;

50

--------------------------------------------------------------------------------

 

               (ii) The words “include,” “includes” and “including” when used
herein shall be deemed in each case to be followed by the words “without
limitation;”

               (iii) The phrase “made available” in this Agreement shall mean
that the information referred to has been provided to or made accessible to the
party to whom such information is to be made available;

               (iv) The phrases “the date of this Agreement,” “the date hereof,”
and terms of similar import, unless the context otherwise requires, shall be
deemed to refer to March 2 2005;

               (v) Any reference to a “Material Adverse Effect” with respect to
any entity or group of entities means any change or circumstance or effect that,

effects, is or would reasonably be expected to be, materially adverse to the
business, assets, property (tangible and intangible), condition (financial or
otherwise), or results of operations of such entity or group of entities, taken
as a whole. For the avoidance of doubt, a failure by such entity or entities to
meet the financial performance expectations of financial analysts for any
quarter prior to the Effective Time or to execute by a specified time any
material contract with a customer shall not, in and of itself, be deemed to be a
Material Adverse Effect on such entity or group of entities;

               (vi) Any reference to a party’s “knowledge” means such party’s
actual knowledge after reasonable inquiry of its directors, officers and other
management level employees that have responsibility for the referenced matters;

               (vii) Any reference to the “prospects” of InterSAN or its

means such prospects or business without taking into account the effects of the
Merger or any changes to InterSAN’s business that are initiated by Finisar
thereafter;

               (viii) The term “Permitted Encumbrances” means (i) Liens for
Taxes, assessments or other charges by Governmental Entities which are not yet
due and payable or are due but not delinquent or are being contested in good
faith by appropriate proceedings, (ii) purchase money security interests
incurred in the ordinary course of business and (iii) minor Liens that will not,
in any case or in the aggregate, materially detract from the value of the assets
subject thereto or materially impair the operations of InterSAN;

               (ix) The word “Subsidiary” means, with respect to any party, any
corporation or other organization, whether incorporated or unincorporated, of
which (i) such party or any other Subsidiary of such party is a general partner
(excluding partnerships, the general partnership interests of which held by such
party or any Subsidiary of such party do not have a majority of the voting
interest in such partnership) or (ii) at least a majority of the securities or
other interests having ordinary voting power to elect a majority of the Board of
Directors or others performing similar functions with respect to such
corporation or other organization is directly or indirectly owned or controlled
by such party or by any one or more of its Subsidiaries, or by such party and
one or more of its Subsidiaries; and
