designated by Inrange for special color orders) is *. The customization
preparation fee for expedited lead-time is *. The initial customization
preparation fee shall be paid at the time that the particular private label
customization is first requested. Thereafter, Ancor shall only be required to
pay an additional customization preparation fee for the Third-Party Private
Label Product if Ancor requests changes in the customization requirements in
that Third-Party Private Label Product. Such additional customization
preparation fee shall be paid at the time that the changes are first requested.
Private label customization shall include only the following features: (a)
replacement of the Inrange logo in its customary placement with the private
label, (b) replacement of the Inrange corporate name in its customary placement
with the customer's name, (c) one designated color paint for the switch cabinet,

and (f) accessory kit composed of two loopback plugs.

      2.2 Ancor Private Label Products. Ancor Private Label Products will not be
subject to customization lead-time or any customization preparation fee. All
Ancor Private Label Products will include the private label customization
features described in Section 2.1 and will be a single color, to be designated
by Ancor.

      2.3 Firm Purchase Orders. All orders for Designated Inrange Products
placed by Purchaser hereunder shall be evidenced by the Purchaser's firm
purchase order and shall be subject to all of the provisions set forth in this
Agreement. By placing each order, the Purchaser confirms its agreement with and
acceptance of all such terms and conditions. In the event of any discrepancy
between the provisions set forth herein, on the one hand, and any purchase
order, order confirmation,

* Confidential Treatment Requested with respect to this information.


                                       3
<PAGE>   4

or other communication between the parties, whether or not acknowledged by the
other party, on the other hand, the provisions hereof shall prevail. In
addition, any additional terms contained in any purchase order, order
confirmation or other communication between the parties, whether or not
acknowledged by the other party, shall not be binding on either party unless
such additional terms are expressly accepted in writing by both parties. No
order for any Designated Inrange Product placed by Purchaser hereunder shall be
binding on Inrange unless, and until, accepted by Inrange. Within five (5)
business days after the receipt of a Purchaser's purchase order hereunder,
Inrange shall either provide a written acknowledgement of acceptance of the
purchase order or written objections to the purchase order. If Inrange fails to
provide any such written acknowledgment or objection within five (5) business
days of its receipt of any Purchaser's purchase order hereunder, the purchase
order shall be deemed to be rejected by Inrange and of no further force and
effect. Purchase orders shall provide details sufficient to identify the
customer, the applicable customized features, and the shipping instructions.

      2.4 Prices. The prices charged to Purchaser for the Designated Inrange
Products shall be as set forth in Schedule 2.4 hereof; the parties shall
mutually agree upon an amendment to said Schedule which will finalize the
pricing for the FC/9000-128 products. Such prices shall remain firm for the term
of this Agreement. The prices set forth in Schedule 2.4 are predicated on
Release 1 of the Designated Inrange Products being generally available for
distribution on or before * and Release 2 of the Designated Inrange Products
being generally available for distribution on or before * (each, a "General
Availability Date"). For each full month prior to its General Availability Date
that a Designated Inrange Product is made generally available for purchase, the
price for such Designated Inrange Product under this Agreement will be subject
to a discount of *% This discount will only apply during the 12-month period
commencing upon the applicable accelerated General Availability Date.
Notwithstanding the foregoing, Ancor may request concessions in the prices for a
Third-Party Private Label Product if Ancor's volume for that Third-Party Private
Label Product exceeds * chassis in a 12-month period. If Ancor is entitled to
and does request a concession in prices as described above, the parties shall
negotiate in good faith to reach a revised price based on the applicable volume.

      2.5 Payment Terms. All prices are expressed, and shall be payable, in
United States Dollars. Payment terms shall be net thirty (30) days from the date
of invoice. Inrange shall issue invoices upon shipment. To the extent Purchaser
shall fail to make payments as specified in this Agreement, or if for any other
bona fide reason Inrange deems itself to be insecure as to payment, Inrange may
demand that Purchaser make full or partial payment in advance, open for
Inrange's benefit irrevocable documentary letters of credit, obtain for
Inrange's benefit bank guaranties, provide current financial statements for
Purchaser, and/or provide other satisfactory security or guaranties that
invoices will be promptly paid when due. All Designated Inrange Products sold
hereunder shall be invoiced to Purchaser, and Purchaser shall be responsible for
invoicing its customer. Inrange reserves the right to charge interest at one and
one half percent (1.5%) per month on any unpaid balance owing by Purchaser from
the date on which the unpaid balance was due to Inrange.

      2.6 Delivery/Shipment.

Products shall pass outside the U.S. Customs territory.

      2.7 Cancellation of Ordered Products. All Designated Inrange Products
ordered hereunder are considered customized products. After Purchaser has
received notice from Inrange of acceptance of an order but prior to the
originally scheduled shipment date, Purchaser will be able to cancel, reduce,
reconfigure or reschedule the order without the prior written consent of
Inrange; provided, however, that Purchaser shall not do so unreasonably and that
any such action shall be subject to the payment requirements set forth in this
Section. Purchaser shall not have the right to take any such action after the
order has been shipped. If, during the period beginning * and ending * prior to
the original shipment date, Purchaser cancels an order, reduces an order by more
than *% or reschedules an order for shipment more than * after the original
shipment date, Purchaser shall pay a charge equal to *% of the purchase price
for the affected Designated Inrange Products. If, during the period beginning *

charge in connection with a cancellation, reduction, reconfiguration or
reschedule of an order.

      2.8 Warranties.

            2.8.1 All sales to Purchaser shall be subject to Inrange's warranty
attached as Schedule 2.8 hereto. Except for permitted modifications to the
Software as described in Sections 2.16 and 2.17, Purchaser agrees that it shall
not in any way alter the Designated Inrange Products (nor the parts or
components thereof) without the prior written authorization of Inrange, nor make
any warranty or representation other than those contained in Inrange's warranty.
Any warranty given


                                       5
<PAGE>   6

by Purchaser with respect to Designated Inrange Products that have been altered
without prior authorization of Inrange or any such additional warranty or
representation shall be void. Claims by Purchaser in regard to any defect in any
Designated Inrange Product shall be made pursuant to claims procedures set forth
in the warranty and this Agreement.

            2.8.2 Inrange further warrants that it shall convey good title to
all Designated Inrange Products sold to Purchaser, free of all security
interests, liens and encumbrances, but subject to any licenses for third-party
software included in the Designated Inrange Products.

      2.9 Disclaimer of Warranties. THE FOREGOING WARRANTIES ARE EXCLUSIVE AND
IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES WHATSOEVER, INCLUDING BUT
NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR PARTICULAR
PURPOSE.

      2.10 Limitation of Liability.

            2.10.1 IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER (OR
SHALL INRANGE BE LIABLE TO ANY PURCHASER OR END USER OF ANY DESIGNATED INRANGE
PRODUCT) FOR ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL OR CONTINGENT
DAMAGES WHATSOEVER, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, INJURIES TO
PROPERTY, LOSS OF USE OF ANY DESIGNATED INRANGE PRODUCT OR ANY ASSOCIATED
EQUIPMENT, WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED THAT THE POSSIBILITY OF
SUCH LOSS, AND WHETHER THE CLAIM IS FOR BREACH OR REPUDIATION OR CONTRACT, TORT,
BREACH OF WARRANTY, NEGLIGENCE, OR OTHERWISE.

            2.10.2 EXCEPT FOR INDEMNIFICATION CLAIMS UNDER SECTION 2.18,
INRANGE'S AND PURCHASER'S LIABILITY UNDER, FOR BREACH OF, OR ARISING OUT OF
THESE TERMS AND CONDITIONS OR SALE AND/OR SALE OR USE OF A DESIGNATED INRANGE
PRODUCT SHALL BE LIMITED TO AN AMOUNT EQUAL TO THE PRICE OF THE AFFECTED
DESIGNATED INRANGE PRODUCT.

            THE ESSENTIAL PURPOSE OF THIS SECTION 2.10 IS TO LIMIT THE POTENTIAL
LIABILITY OF THE PARTIES ARISING OUT OF THESE TERMS AND CONDITIONS OF SALE, THE
PURCHASE AND SALE OF DESIGNATED INRANGE PRODUCTS HEREUNDER, AND ARE DESIGNATED
INRANGE PRODUCTS SOLD HEREUNDER.

      2.11 Liability Insurance. Each party shall maintain in effect appropriate
liability (including product liability) insurance policies with a recognized
carrier providing for coverage of not less than two million U.S. Dollars
($2,000,000). Upon written request, Purchaser shall provide to Inrange a
certificate of insurance evidencing the above coverage.

      2.12 Claims Procedure. Any claim against Inrange for shortages in or
damages to any Designated Inrange Product shipped to Purchaser shall be made in
accordance with Inrange's


                                       6
<PAGE>   7

standard procedures and other written instructions conveyed to Purchaser by
Inrange from time to time. Any other claims against Inrange arising out of
Designated Inrange Products sold to Purchaser shall be made within ninety (90)
days after Purchaser first knows or has reason to know of such claim. All such
claims shall be submitted to Inrange in writing and shall set forth in full the
details, basis, and amount of such claim against Inrange. Failure by Purchaser
to provide proper documentation to support an insurance claim that then results
in total or partial denial of coverage shall render Purchaser liable to Inrange
for all amounts unpaid.

      2.13 Product Modification or Discontinuance. Inrange will include
Purchaser in its engineering change order ("ECO") process with respect to the
Designated Inrange Products; however, Purchaser will not have any approval
rights with respect to Inrange's ECO process. Inrange may at any time make
changes in any Designated Inrange Product (whether in design, material, the
addition of improvements, or otherwise) and may discontinue the manufacture of
any Designated Inrange Product, all in its sole discretion, without incurring
any obligation of any kind as a result thereof. Inrange shall notify Purchaser
with as much advance notice as possible of changes to form, fit or function
which affect the Designated Inrange Products or the private label customization
features. Purchaser may request a delay in the implementation of a change to
form, fit or function in response to specific requirements from a customer, and
Inrange shall use reasonable efforts to accommodate such request; provided,
however, in no circumstance will Inrange be required to support any version of a
Designated Inrange Product other than the then-current version, the two
immediately preceding software versions, and the one immediately preceding
hardware version. Inrange shall notify Purchaser six (6) months in advance of
its discontinuance of the manufacture of any of the Designated Inrange Products,
and shall use reasonable efforts to support any discontinued Designated Inrange
Products for three (3) years after the sale. Purchaser may request an extension
of the support period in response to specific requirements from a customer, and
Inrange shall use reasonable efforts to accommodate such request; provided,
however, in no circumstance will Inrange be required to support any version of a
Designated Inrange Product other than the then-current version, the two
immediately preceding software versions, and the one immediately preceding
hardware version.

            Purchaser will include Inrange in its ECO process with respect to
the Designated Inrange Products; however, Inrange will not have any approval
rights with respect to Purchaser's ECO process. Purchaser shall notify Inrange
with as much advance notice as possible of changes to form, fit or function
which affect the Designated Inrange Products or the private label customization
features. Within five (5) business days of Inrange's receipt of a requested
change from Purchaser, Inrange will respond to Purchaser with a projected cut-in
date.

      2.14 Offsets. Any credits, allowances, or other amounts payable or
creditable to Purchaser by Inrange shall be subject to offset for any claims or
other amounts owed by Purchaser to Inrange pursuant to the provisions hereof or
otherwise.

      2.15 Security. As security for payment and performance of all of
Purchaser's obligations and liabilities to Inrange under this Agreement,
Purchaser grants to Inrange a security interest in all of the Designated Inrange
Products acquired by Purchaser pursuant to this Agreement, and in all proceeds
of any such Designated Inrange Products. Upon request by Inrange, Purchaser
agrees to


                                       7
<PAGE>   8

execute and deliver to Inrange any and all financing statements or other
instruments or documents reasonably necessary in order to establish, perfect, or
maintain such security interests.

      2.16 Software License. Designated Inrange Products delivered by Inrange
hereunder may contain or require the use of separable Software (the "Software"),
which is defined herein to include (i) computer programs consisting of
hard-wired logic instructions and/or instruction sequences in machine-readable
code, contained on a magnetic tape, diskette, semiconductor device or other
memory device or system memory which provides basic logic, operating
instructions and user-related application instructions and (ii) documentation
used to describe, maintain and use the programs. Inrange and Purchaser
acknowledge and agree that such Software includes Ancor Technology, Inrange
Technology and Developed Technology, which technologies are owned by Inrange
and/or Purchaser as stated in the Technology License Agreement. Notwithstanding
any other provisions of this Agreement and/or reference to "sale" of Designated
Inrange Products in this Agreement or Inrange's terms and conditions, the title
to, and ownership of, the Software shall remain in Inrange; provided, however,
that Inrange's and Purchaser's respective rights with respect to all Ancor
Technology, Inrange Technology and Developed Technology (even if included in the
Software) shall be as stated in the Technology License Agreement notwithstanding
Inrange's ownership of the compilation of all such technologies as embodied in
the Software.

            Inrange hereby grants to Purchaser a personal, non-exclusive,
non-assignable license to distribute and sublicense to Purchaser's OEMs and
their end users the object code for the Software for use solely in connection
with the Designated Inrange Products sold pursuant to this Agreement and subject
to Inrange's standard software license terms (which terms shall not apply to any
Ancor Technology or Developed Technology except as those technologies are
embodied in the Software).

            Inrange further grants to Purchaser a personal, non-exclusive,
non-assignable license to use, modify, create derivative works from, port,
integrate and translate the source code for the Software for use solely in
connection with the Designated Inrange Products sold pursuant to this Agreement
and subject to reasonable restrictions imposed by Inrange for protection of its
source code. Inrange further grants to Purchaser's OEMs the right to modify the
source code for the Software as required to perform private label customization
(i.e. change of logo and name) of the Software solely in connection with the
sale of Designated Inrange Products pursuant to this Agreement and subject to
reasonable restrictions imposed by Inrange for protection of its source code. On
a case-by-case basis, at Purchaser's request, Inrange will consider extending to
Purchaser the right to sublicense Purchaser's OEM to use, modify, and create
derivative works from the source code for the Software for use solely in
connection with the Designated Inrange Products sold pursuant to this Agreement.
The grant of such right to sublicense shall be subject to reasonable
restrictions imposed by Inrange for protection of its source code.
Notwithstanding the foregoing, the parties acknowledge and agree that the
Software may include certain third-party software and that Purchaser's rights
with respect to the source code for the Software will not extend to any such
third-party software.

            Inrange will not be responsible for any errors arising from the
content of those portions of the Software modified by Purchaser or any errors in
compilation arising from Purchaser's modification of the Software. Purchaser
will pay to Inrange, in addition to any other fees payable


                                       8
<PAGE>   9

under this Agreement, the cost of any license fees or charges related to any
third-party software included in the Software if Purchaser elects to have
Inrange deliver to Purchaser such third-party software as part of the Software.

            All rights, including copyrights, in the Software shall be retained
by Inrange (subject to Purchaser's ownership rights in and to the Ancor
Technology and Developed Technology embodied in the Software), and Purchaser
shall not have any right to copy or use the Software (whether modified or
unmodified) except as provided in this Agreement. Notwithstanding anything to
the contrary herein, Purchaser's rights to use, modify, distribute and create
derivative works of the Ancor Technology and Developed Technology, as stated in
the Technology License Agreement, shall not be restricted or prohibited in any
way by this Agreement, even if such Ancor Technology and Developed Technology is
also embodied in the Software; however, Purchaser's actions with respect to the
Software itself shall be in accordance with this Agreement

            If Purchaser's OEMs or their end user need support for
modifications, integration, interface or new features, Purchaser may request
that Inrange provide such support for a mutually acceptable NRE charge. Inrange
will use its reasonable efforts to accept reasonable requests by Purchaser for
customer customization requirements.

            Purchaser agrees further to enter into sub-license agreements with
its OEMs and to cause its OEMs to enter into sub-license agreements with their
end users, which, at a minimum, provide that (a) OEM or end user will keep
confidential and protect the Software and associated documentation from
unauthorized disclosure; (b) any reproduction of the Software shall be solely
for backup or archival purposes; (c) except as authorized in this Section 2.16,
OEM or end user will not modify or attempt to modify the Software without the
written consent of Inrange; (d) no transfer of title to the Software to OEM or
end user shall be deemed to have occurred by virtue of such sub-license; and (e)
the end user will use the Software solely in connection with the Designated
Inrange Products sold pursuant to this Agreement and for its internal business
purposes.

      2.17 Modification of Inrange's Java/Browser Control Software. As part of
the license to the Software described in Section 2.16, Inrange grants to
Purchaser a license to modify that portion of Inrange's Java/Browser Control
Software (the "JBC Software") which is based on Purchaser's source code and
included in the Designated Inrange Products, but solely for the purpose of (i)
replacing Inrange logos and name references with the logos and name references
of Purchaser or Purchaser's OEMs, as applicable, and revising pictures and
diagrams to conform to the private label customization features of the
Designated Inrange Products or (ii) modifying and creating derivative works of
the Ancor Technology and Developed Technology embodied in the JBC Software
solely for use in connection with Designated Inrange Products sold pursuant to
this Agreement. Purchaser will furnish the modified JBC Software files to
Inrange, and Inrange will produce the modified JBC Software for shipment with
the Designated Inrange Products. Inrange's obligation with respect to the JBC
Software will be limited to error-free compilation of the unmodified Inrange
portion. Inrange will not be responsible for any errors arising from the content
of those portions of the JBC Software modified by Purchaser or any errors in
compilation arising from Purchaser's modification of the JBC Software. Purchaser
will pay to Inrange, in addition to any other fees payable under this Agreement,
the cost of any license fees or charges related to any third-party software
included in the


                                       9
<PAGE>   10

JBC Software if Purchaser elects to have Inrange deliver to Purchaser such
third-party software as part of the JBC Software.

            All rights, including copyrights, in the JBC Software shall be
retained by Inrange (subject to purchaser's ownership rights in and to the Ancor
Technology and Developed Technology embodied in the JBC Software), and Purchaser
shall not have any right to copy or use the JBC Software (whether modified or
unmodified) except as provided in this Agreement. Notwithstanding anything to
the contrary herein, Purchaser's rights to use, modify, distribute and create
derivative works of the Ancor Technology and Developed Technology, as stated in

      2.18 Indemnification.

            2.18.1 Inrange shall defend, indemnify and hold harmless Purchaser
its officers, directors, employees, successors, and assigns, against any losses,
damages, or expenses of whatever form or nature, including attorneys' fees and
other costs of legal defense that they, or any of them, may sustain or incur as
a result of any third party suit, proceeding, claim or other legal action
(collectively. "Third Party Action") insofar as such Third Party Action is based
on a claim that a Designated Inrange Product or its use, manufacture (as
provided in Section 6.5), import or sale as permitted hereunder, constitutes an
infringement of any issued United States patent or copyright. The foregoing
indemnification obligation of Inrange shall be subject to (i) Purchaser promptly
notifying Inrange of any such Third Party Action and furnishing Inrange a
complete copy of each communication, notice or other action relating to the
alleged infringement. (ii) Inrange being given authority, information and
reasonable assistance necessary to settle, compromise or litigate such Third
Party Action, and (iii) no settlement of any Third Party Action being made
without the express permission of Inrange. If the Designated Inrange Product is
held in any such Third Party Action to infringe and the use of the Designated
Inrange Product is enjoined, or in the case of a settlement as described above,
Inrange shall, at its own expense, either procure for Purchaser a right to
continue using the Designated Inrange Product or replace same with a
noninfringing Designated Inrange Product, or modify same to make it
noninfringing, or, if Inrange cannot reasonably accomplish one of the foregoing
remedies, refund the depreciated value of the Designated Inrange Product and
accept the return of same.

            2.18.2 Inrange shall not be obligated to defend or be liable for
costs and damages if infringement as described in this Section arises out of (i)
compliance with Purchaser's specifications, (ii) incorporation of any Ancor
Technology in the Designated Inrange Product, (iii) any combination or use of
the Designated Inrange Product with materials or technology not furnished by
Inrange if such infringement would have been avoided by use of the Designated
Inrange Product alone, (iv) a modification of the Designated Inrange Product
after delivery by Inrange if the infringement would have been avoided without
such modification, or (v) other fault or action of Purchaser. In any of these
cases, Purchaser will indemnify and defend Inrange on the basis described in the
preceding


                                       10

subsection. Inrange may decline to make further shipments to Purchaser under
this Agreement if infringement caused by any such action of Purchaser has been
alleged or has occurred.

            2.18.3 The foregoing states the entire liability of Inrange for
patent, copyright, or other intellectual property infringement by The Designated
Inrange Products furnished hereunder. The obligations under this Section shall
survive the termination of this Agreement for any reason.

<PAGE>   19

breach is not susceptible of cure within such period, has failed to commence
such cure within such period;

            (d) Failure by Inrange to deliver at least 80% of the delivery

becomes effective and does not permit Purchaser to use Inrange's Confidential
Information to develop new products.

      6.6 Escrow. Within sixty (60) days alter execution of this Agreement,
Inrange and Purchaser and Purchaser's designated independent escrow agent will
execute a three party escrow agreement, consistent with the terms of Section
6.5, providing for the release of deposit materials in escrow to Purchaser upon
the occurrence of a Trigger Event. Within sixty (60) days after Inrange's first
sale of a Designated Inrange Product to Purchaser pursuant to this Agreement,
Inrange will deliver to the escrow agent all Inrange Confidential Information
required for the manufacture of the Designated Inrange Product. Inrange shall
update such escrow account from time to time during the term of this Agreement,
but no less than once in every six (6) month period, in order to keep such
account current. Purchaser shall pay all costs, fees and charges of the escrow
agent. Purchaser will use Inrange Confidential Information released by the
escrow agent only in connection with its right under Section 6.5 and will return
all such Inrange Confidential Information to Inrange upon the expiration or
termination of such right. Notwithstanding the foregoing, if Purchaser transfers
any of the Inrange Confidential Information to a third party in order to have
the Designated Inrange Product manufactured as contemplated in Section 6.5, then
(a) only such Inrange Confidential Information as is necessary to manufacture
the Designated Inrange Product may be transferred and (b) such third party shall
execute a written nondisclosure agreement that is at least as protective of
Inrange's rights in such transferred Inrange Confidential Information as is
provided

under this Agreement. Upon any release of the deposit materials in escrow to
Purchaser pursuant to such escrow agreement, Inrange shall have no further
obligation to maintain or update the escrow account. Further, upon the
expiration or termination of Purchaser's right to purchase Designated Inrange
Products pursuant to this Agreement, the escrow agreement shall be terminated
and all deposit materials in escrow shall be returned to Inrange.

written consent of the other party, whose consent shall not be unreasonably
withheld, except that no consent shall be required for Inrange to assign or
otherwise transfer its rights and/or obligations under this Agreement to one or
more of Inrange's affiliates (i.e., an entity that controls, is controlled by,
or is under common control with Inrange). Any prohibited assignment shall be
null and void.

      7.7 Announcements. The terms and conditions of this Agreement are

approved, in writing, by the referenced party prior to publication or release.

      7.8 Waivers. Any failure of either party to comply with any obligation,
covenant or agreement herein may be waived in writing by the other party, but
such waiver or failure to insist upon strict compliance of such obligation,
covenant or agreement shall not operate as a waiver of, or estoppel with respect
to, any subsequent or other failure.

counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same agreement.
