rights not expressly granted to Inrange hereunder, including without limitation,
the right to sell, lease, license and distribute the Ancor Products (whether on
a chip, component, board or box level, but excluding the Boards), on a worldwide
basis in all markets other than the Inrange Market. The parties shall negotiate
in good faith a reduction of the royalty rate provided for in Section 3.3 if a
final unappealable judgment from a court of competent jurisdiction prohibits
Ancor from fulfilling its obligations under this Section 2.2 which reduction
shall be effective from the date Ancor does not fulfill its obligations.

      2.3 Sublicenses. The rights granted to Inrange under Section 2.1 may not
be sublicensed, transferred or assigned to any third party except with the prior
written consent of Ancor; which may not be unreasonably withheld, provided that
Inrange may sublicense its rights hereunder without such consent to any
affiliate of Inrange. As used herein, the term "affiliate" means any corporation
or business entity that controls, is controlled by or is under common control
with Inrange, with "control" meaning beneficial ownership of 50% or more of the
voting stock of, or a 50% or greater interest in the income of, such corporation
or other business entity, or the maximum ownership permitted by law or
administrative practice.

      2.4 Distribution in Inrange Market. Inrange shall have the right to
distribute the Inrange Products through its direct sales force, OEM
manufacturers, systems integrators, distributors and the like; provided that (a)
any OEM, systems integrator or distribution agreement shall contain terms
consistent with the terms hereof; and (b) Inrange shall use good faith efforts
to enforce such agreements against such OEMs, system integrators, distributors
and the like.

      2.5 Distribution of Software. Any and all distribution of the Software

with respect to the Software, only the licensing of that Software, in object
code format, pursuant to the terms of such license agreement.

      2.6 Rights to S-16 Products. The parties agree to include the S-16.X
series of Fibre Channel Switch chips as an ASIC subject to this Agreement,
subject to (a) payment by Inrange of a non-refundable license fee of $4 million
and (b) renegotiation of royalties payable hereunder for both the S-4.X and
S-16.X series of ASICs, to be negotiated in good faith by the parties within
thirty (30) days after Inrange notifies Ancor in writing of its desire to
include the S-16.X series.

      2.7 Licensee Obligations.

            (a) Best Efforts. Inrange shall use its best efforts, consistent
with its business plan, to further the promotion, marketing, and distribution of
the Inrange Products.

            (b) Reverse Engineering. Except to the extent that Inrange has
rights to Source Code, Inrange shall not reverse engineer, decompile or
disassemble the Software (including without limitation any portions thereof that
are embedded as firmware) and shall not knowingly allow any other person to do
so.

      2.8 Prices to OEMs, Distributors. Inrange shall, in its sole discretion,
determine the prices to be paid by third parties for the Inrange Products.

      2.9 OEM Agreement. The parties shall use their best efforts to negotiate

terms of which shall include (a) the appointment of Inrange as a nonexclusive
worldwide OEM distributor of Ancor's standard products; (b) pricing for such
products on a most-favored customer basis with respect to other OEM distributors
purchasing similar volumes of such products, and (c) other customary and
reasonable terms to be mutually agreed by the parties.

3. LICENSE FEE AND ROYALTIES

      3.1 License Fee. In consideration of the rights granted hereunder, Inrange
shall pay to Ancor a license fee of $* million, payable as follows: $* million
on the date this Agreement becomes effective as provided in Section 5.3 below,
$* million on or before December 15, 1998 and $* mi1lion on or before March 31,
1999. Such license fee shall be non-creditable and nonrefundable.

      3.2 Prepaid Royalties. Inrange shall pay to Ancor, on or before March 31,
1999, $* million in prepaid royalties. In consideration of such prepayment,
Inrange shall be entitled to a dollar for dollar credit of $* against royalties
which accrue under Section 3.3. The unused balance of such prepaid royalties
shall be refunded to Inrange in the following events: (a)

     *Confidential treatment requested with respect to this information.


                                      -5-
<PAGE>   6

the occurrence of any of the conditions set forth in Section 5.3; (b) the
acquisition or merger of Ancor with, or the sale of all of its assets to, any
Inrange competitor, or (c) the failure of the ASICs to meet the Descriptions,
which failure is not remedied within ninety (90) days written notice thereof
from Inrange or if such failure is not susceptible of cure within such period,
the failure of Ancor to commence implementation of a mutually agreed plan to
remedy such failure within such period. If the prepaid royalties are refunded to
Inrange on or before December 31, 1999, pursuant to this Section 3.2, the full
royalties set forth in Section 3.3 below shall apply to sales of Inrange
Products which occur after the date of the event giving rise to the refund. If
the refund occurs on or after January 1, 2000, the royalty payable by Inrange on
Inrange Products pursuant to Section 3.3 below shall be discounted in an amount
equal to * of the refunded prepaid royalty multiplied by the number of years
elapsing be the date of payment of the prepaid royalty (March 31, 1999) and the
date of the event giving rise to the refund. The discount shall be applied, on a
dollar for dollar basis, to royalties accrued by Inrange commencing upon said
date, until such the total discount amount exhausted.

      3.3 Royalties to Ancor.

      (a) Subject to Sections 3.2 and 3.4, Inrange shall pay Ancor the following
royalties for each Inrange Product sold, licensed, leased, distributed or
otherwise transferred by or on behalf of Inrange to any third party:

<TABLE>
<CAPTION>
            Product                       Royalty
            -------                       -------
            <S>                           <C>
            FC/9000                       *
            CD/9000                       *
            Broadband                     *
            All other Inrange Products    *
</TABLE>

Such royalty shall accrue on the date of sale, license, lease, distribution or
other transfer of such Inrange Product to such third party, and shall be payable
on a calendar quarterly basis, within 30 days of the end of the quarter in which
such royalty obligation accrued. Notwithstanding the generality of the
foregoing, no royalty obligation shall accrue upon the transfer of Inrange
Products to customers for the purpose of maintenance and repair if the transfer
of the Inrange Products is not revenue generating. Along with each such royalty
payment, Inrange shall provide a report showing the model/type and number of
units of Inrange Products (and the corresponding number of user ports, if
applicable) sold, licensed, leased, distributed or otherwise transferred during
such quarter. The above royalty rates may be renegotiated in good faith based on
market pricing, competitive pressures or Inrange's sales volume.

      (b) Should Ancor, during the term of this Agreement, grant to any
independent third party selling fibre channel connectivity products a license of
Ancor Technology on terms which, when viewed in their entirety (including,
without limitation, initial license fees, royalty rates charged and minimum
annual royalties due) are more favorable than the terms granted to Inrange


                                      -6-
<PAGE>   7

hereunder, then Ancor shall promptly provide to Inrange a correct and complete
summary of such more favorable terms.

      (c) Inrange shall be entitled, upon written request within ninety (90)
days after receipt of such summary from Ancor, to have the royalty terms in this
Agreement replaced with the more favorable terms, and the parties will effect an
appropriate amendment to this Agreement which shall be effective as of the date
Ancor receives such request from Inrange. Such amendment shall not affect any
transactions by the parties hereunder prior to its effective date. In no case
shall this provision be construed to impose any obligation on Ancor to repay to
Inrange any royalties previously paid pursuant to this Agreement or any
antecedent license agreement concerning the Ancor Technology.

      3.4 Limitation on Exclusivity. The anticipate that, by December 31,2000,
Inrange Products shall have attained at least * market share (the "Minimum
Market Share"). Thereafter, the Minimum Market Share for each year this
Agreement is in effect will be mutually agreed to by the parties by December 31
of the prior year (i.e., the Minimum Market Share for 2001 will be agreed to by
December 31, 2000). If the parties fail to agree whether the actual market share
attained by Inrange Products for a particular year meets the Minimum Market
Share for such year, then each party will select one (1) independent nationally
recognized market analyst within forty-five (45) days of the end of such year to
determine and certify whether the applicable Minimum Market Share was met during
the prior year. If the two analysts do not agree, then they shall appoint a
third analyst, and the conclusion of two of the three analysts shall control. If
two of the analysts determine that the Minimum Market Share was not met in a
particular year, they shall also be required to deliver, by the end of the first
quarter of the next calendar year, a written report setting forth in detail the
reasons for the failure and make recommendations so Inrange may attain the
Minimum Market Share by the end of the second fiscal quarter following delivery
of such report. Inrange shall adopt a specific, mutually agreeable plan based on
the analysts' recommendations so as to achieve the Minimum Market Share in the
next year. The costs of the analysts shall be borne equally by the parties. If
Inrange does not meet the Minimum Market Share by the end of the second fiscal
quarter following delivery of the report in any particular calendar year, then
Ancor may, at its option terminate the covenant set forth in Section 2.2.
Notwithstanding the foregoing, Ancor may not exercise this option referred to in
the preceding sentence if the analysts conclude that the failure of Inrange to
meet the Minimum Market Share in a particular calendar year is principally due
to any factor within the reasonable control of Ancor, including, without
limitation, problems with ASICs' supplier(s) or defects in ASIC and Board
designs.

      3.5 Audit Rights. Inrange shall keep adequate and complete books and
records related to the sales of the Inrange Products for a period of no less
than five (5) years following completion of the fiscal year in which the sale of
the Inrange Product occurred. Such books and records shall include all
information necessary to verify the total amount and computation of the sales of
such Products. Upon request, but no more than once per calendar year, Inrange
shall provide Ancor's independent auditors with access, during regular business
hours and upon


                                      -7-
<PAGE>   8

reasonable prior notice, and subject to the undertakings contained in this
Agreement, to Inrange's books and records relating to the Inrange Products
solely for the purpose of verifying the accuracy of the calculations hereunder.
If such audit shows any underpayment or overpayment, a correcting payment or
refund, together with interest at the current prime lending rate established by
leading New York banks as published in The Wall Street Journal, shall be made
within thirty (30) days of completion of such audit and submission of the
results thereof, with details of the calculations included therein. The costs of
such audit shall be borne by Ancor; provided that Inrange shall reimburse Ancor
its actual out-of-pocket expenses of such audit, if such audit reveals any
underpayment of amounts owing hereunder of more than ten percent (10%) for any
period covered by such audit.

      3.6 Tax Withholding. If any taxes are imposed as a result of this
Agreement or the performance of the parties hereunder, such taxes shall be borne
and paid by the party required to do so under applicable law or treaty. If law
or regulations in any country require that taxes be withheld, Inrange will (a)
deduct those taxes from the applicable royalty payment, (b) timely pay the taxes
to the proper taxing authority, and (c) furnish Ancor with a certificate of the
relevant tax authorities within such country, in a form issued by such tax
authorities and reasonably acceptable to the U.S. Internal Revenue Service,
documenting payment of such taxes.

4. DEVELOPMENT OF BOARDS, TECHNICAL ASSISTANCE AND TRAINING

      4.1 Development. Ancor agrees to design and develop, on behalf of Inrange,
the four (4) Boards in accordance with the Descriptions and the development
program set forth on Exhibit 4, including the project development schedule
established as part of the development program. The parties agree to fully
cooperate in developing the Boards, and to provide all reasonably necessary
information and resources so that the contemplated development program, along
with its schedule, may be met; provided that if such schedule is not met due to
the fault of a party, the other party shall not be deemed to be in default of
this provision. Each party shall designate an individual to coordinate
communications between the parties with respect to development and technical
assistance activities hereunder.

      4.2 Cost of Development. In consideration of such design and development
services hereunder, Inrange agrees to pay Ancor $* in development fees for the
first three (3) Boards listed on Exhibit 3, payable as follows: $* or each of
the three (3) Boards upon each of the following events: (1) start of the
functional requirements document therefor, (2) completion of the Beta Level
design of the applicable Board as agreed by Inrange, such agreement not to be
unreasonably withheld, and (3) final release by Inrange of the applicable Board.
Inrange also agrees to pay Ancor for development of the Internet Protocol or
Tunneling Board for Inrange's broadband products at a rate of $* per staff month
(i.e., 180 hours), not to exceed $* Ancor's responsibility in providing
assistance is limited to the Fibre Channel portion of the Board and layout, and
does not include changes to the ASICs for this Board. Such payments shall be
non-creditable and non-refundable.


                                      -8-
<PAGE>   9

      4.3 Additional Development. Upon Inrange's request, Ancor shall provide
reasonable development services, in addition to those development services
provided under Section 4.1, for development of additional boards incorporating
the ASICs, subject to availability of appropriate engineering personnel and
mutual agreement on the scope of such development services, at the rate of $*
per staff month.

      4.4 ASIC Redesign. If, during the term of this Agreement, the ASICs become
obsolete, Inrange may notify Ancor of such obsolescence and the parties shall
negotiate in good faith to determine what changes, if any, need to be made to
the ASICs and how the costs of such development should be allocated between
them. Ancor shall provide to Inrange within fourteen (14) days (or such longer
period as the parties may agree) of Inrange's notice a proposed development plan
for such change and the parties shall negotiate a mutually agreed final
development plan within fourteen (14) days (or such longer period as the parties
may agree) of Inrange's receipt of Ancor's submittal. For the purpose of the
preceding sentence, "obsolete" shall mean that the ASICs have become, for any
reason, incapable of providing the features contracted for in this Agreement, in
accordance with the Descriptions, and/or remaining current with industry
standards (applicable only to the Inrange Market) and competitive products in
the Inrange Market, on a going-forward basis. The parties also understand that
market changes may necessitate changes to the ASICs. If the necessary
non-recurring engineering required for such development affects or responds to
all markets for the ASICs, Ancor shall bear the major portion of the costs of
such non-recurring engineering, and if the necessary non-recurring engineering
primarily affects or responds to the Inrange Market, Inrange shall bear the
major portion of costs for such non-recurring engineering. Notwithstanding the
foregoing, Ancor shall bear the costs of assuring backward compatibility of any
redesign of the ASICs. Notwithstanding any ASIC redesign hereunder, during the
term of this Agreement, Ancor covenants, at its cost, to maintain the
functionality of the ASICs, as set forth in the Description for the ASICs and to
support then current fibre channel standards for all Class 1, 2 and 3 of fibre
channel connectivity. Within fourteen (14) days (or such longer period as the
parties may agree) of the date of Inrange's notice of noncompliance, Ancor shall
produce an action plan acceptable to Inrange for the correction of an ASIC
redesign that is not backward compatible or fails to conform to the Descriptions
or the then current fibre channel standards.

      4.5 Technology Transfer and Technical Assistance. Ancor shall not be
required hereunder to produce or provide detailed documentation for the ASICs,
but will work with Inrange to transfer necessary Ancor Technology relating to
applying the ASICs to the Boards in a timely manner. Such transfer shall be
accomplished by allowing Inrange engineers to monitor the Board design process
and to attend design reviews for the Boards, and providing to Inrange pertinent
technical information and/or documentation as reasonably required to
successfully complete the transfer. Inrange shall allocate* to monitor the Board
design process, attend such design reviews for the Boards and participate in the
training to be provided pursuant to Section 4.6. Ancor and Inrange shall also
engage in joint VHDL Simulation to enable Inrange to complete systems
integration of the ASICs into the Inrange Products, and shall use their best
efforts to resolve integration issues. In addition, Ancor will make available to


                                      -9-
<PAGE>   10
Inrange an engineer to provide "Application Engineer" Level assistance on
Inrange Products that incorporate the ASICs on a dedicated full time basis, for*
during the development of such Inrange Products or completion of the Boards,
whichever is longer,* , and thereafter, on an as-needed part time basis, at a
rate of * per staff month (i.e., 180 hours). Ancor further agrees to make
available sufficient technical resources to perform timely (i.e., within five
days unless otherwise agreed by both parties) and effective technical support to
correct design defects and perform bug fixes on the Boards.

      4.6 Training. Ancor shall provide reasonable training and documentation,
at*, in the use of the object code of the Software to Inrange's technical staff,
and in the use of the Ancor Products generally, to Inrange's sales and support
personnel; provided, however, that Inrange shall bear the travel and living
expenses of such personnel. The parties agree that such training shall follow
the "train the trainer" model.

      4.7 Sales and Marketing Support. Ancor shall provide Inrange with limited
sales and marketing support as reasonably requested by Inrange, including visits
to Inrange customers, participation by Ancor in one sales meeting per year and
in one Inrange Customer Advisory Council meeting per year; provided, however,
that Inrange shall bear the travel and living expenses of such personnel.

5. PURCHASE AND SUPPLY OF ASICS

      5.1 Purchase from Ancor's Third Party Manufacturer. Inrange acknowledges
that the ASICs are manufactured for Ancor by a third party foundry, LSI Logic
("LSI"), and that Inrange shall purchase all ASICs directly from LSI or its
distributors pursuant to written purchase orders submitted by Inrange directly
to LSI or its distributors. Ancor agrees to authorize LSI and its distributors,
in writing, to supply the ASICs directly to Inrange solely for incorporation
into the Inrange Products and resale into the Inrange Market. If Inrange cannot
agree to terms with LSI, then Ancor shall supply ASICs to Inrange pursuant to
written purchase orders, at Ancor's cost plus administrative expenses of * which
administrative expenses shall be capped at * per calendar year.

      5.2 Continuing Supply, Price and Quality of ASICs. Notwithstanding Section
14.6, Ancor agrees that if LSI or its distributors do not provide ASICs in the
quantities or at the price agreed with Inrange, or provide ASICs that do not
meet the performance warranties agreed with Inrange (as set forth in Exhibits 1,
2 and 3 hereof), Inrange shall so notify Ancor in writing and Ancor shall use
its best efforts to remedy such failures within forty-five (45) days of such
notice to Ancor, including if the parties deem appropriate after good faith
negotiations, locating and qualifying a second manufacturer for the ASICs and
porting the necessary Ancor Technology to such second manufacturer. The parties
shall mutually agree on how the costs of such technology porting shall be borne.

            (d)   Any Change of Control of Ancor that is not approved by a
                  majority of the Continuing Directors (as defined herein). The
                  term "Continuing Directors" shall mean those individuals who
                  are members of Ancor's Board of Directors on the date hereof
                  and any individual who subsequently becomes a member of
                  Ancor's Board of Directors, if such individual's nomination
                  for election or election to Ancor's Board of Directors is
                  approved by a vote of at least a majority of the Continuing
                  Directors; provided that no individual shall be considered a
                  Continuing Director if such individual initially assumed
                  office as a result of either an actual or threatened "Election
                  Contest" (as described in Rule 14a-1 promulgated under the
                  Exchange Act) or other actual or threatened solicitation of
                  proxies or consents by or on behalf of any entity or person
                  other than the Ancor Board of Directors (a "Proxy Contest")
                  including by reason of any agreement intended to avoid or
                  settle any Election Contest or Proxy Contest.

            (e)   Ancor or any successor thereto has materially breached this
                  Agreement, and has failed to cure such breach within thirty
                  (30) days written notice hereof from Inrange or, if such
                  breach is not susceptible of cure within such period, has
                  failed to commence such cure within such period; or

            (f)   LSI (or any successor foundry for the ASICs) or Ancor fails to
                  supply the ASICs in the quantities subject to purchase orders
                  accepted by LSI (or any successor foundry) or Ancor, as
                  applicable, pursuant to the supply arrangement between LSI (or
                  any successor foundry), or Ancor and Inrange, as contemplated
                  under Section 5.1 for a period of thirty (30), or access to
                  such ASICs is materially disrupted for a period of thirty (30)
                  days; provided that Ancor has not created a plan to cure such
                  failure within thirty (30) days that is reasonably acceptable
                  to Inrange.

If Inrange is entitled to access such Ancor Technology, Inrange shall have the
nonexclusive, nontransferable and non-sublicenseable (except as expressly
provided below) right, pursuant to such escrow agreement, to design, modify, use
and create derivative works of the Ancor Technology solely for the purposes of
(1) manufacturing or having manufactured the ASICs solely for incorporation into
the Boards or the Inrange Products; (2) modifying the ASICs as contemplated in
Section 4.4; (3) modifying the Boards or Inrange Products; (4) using,
reproducing and distributing the Software (in object code format only) in
connection with the Boards and the Inrange Products; (5) designing,
manufacturing, marketing, selling, leasing,


                                      -12-

servicing and sublicensing Inrange Products, and for no other purpose, and
Inrange shall continue to pay royalties with respect to the Inrange Products
pursuant to Section 3.3. In addition, Ancor agrees to provide reasonable
assistance to Inrange, to the extent that Ancor has engineering staff then
available, to achieve an orderly transition from ASIC to technology utilization.
Notwithstanding the foregoing, if Inrange is required to transfer any of the
Ancor Technology to a third party in order to have the ASICs manufactured as
contemplated above, then (a) only such Ancor Technology as is necessary to
manufacture the ASICs may be transferred, and (b) such third party shall execute
a written nondisclosure agreement that is as least as protective of Ancor's
rights in such transferred Ancor Technology as is provided hereunder. Upon any
release of the deposit materials in escrow to Inrange pursuant to such escrow
agreement: (1) Ancor shall have no further obligation to maintain or update the
escrow account; (2) Ancor's obligations under Sections 4.3, 4.4, 4.5, 4.6 and
4.7 shall only continue for a period of two years following the release of the
materials in escrow, provided, however, Ancor's obligation to redesign ASICs
under Section 4.4 shall be limited to*; and (3) Ancor's obligations under
Section 5.2 shall terminate, provided, however, if Inrange thereafter proposes
to locate and qualify a second manufacturer for the ASICs and port the necessary
Ancor Technology to such second manufacturer (collectively, a "Second
Sourcing"), (i) Ancor will participate and provide technical assistance with
respect to such Second Sourcing only to the extent mutually agreed by the
parties after good faith negotiations and (ii) Inrange shall be entitled to a
discount of * off the royalties payable to Ancor under Section 3.3 until such
time as Inrange has recovered, through such discounts, the costs of the Second
Sourcing (excluding any costs borne by Ancor), which costs shall be documented
by Inrange to Ancor within a reasonable period of time after such costs are
incurred.

6. EXPORT CONTROL AND OTHER GOVERNMENTAL APPROVALS

            not permitted under a general license established under the United
            States Export Administration Regulations unless and until Ancor
            shall have applied for and obtained, at the request and expense of
            Inrange, an individual validated license from the Office of Export
            Administration, United States Department of Commerce for such
            reexport.

affecting this Agreement and its performance hereunder and, without limiting the
generality of the foregoing, shall maintain all registrations with governmental
agencies, commercial registries, chambers of commerce, or other offices which
may be required under local law in order to enable it lawfully to conduct its
business and perform its obligations under this Agreement. In addition, Inrange
acknowledges that Ancor is subject to certain United States laws, including but
not limited to the Foreign Corrupt Practices Act, which apply to activities
carried out on its behalf outside the United States and agrees to neither take
nor omit to take any action if such act or omission, as the case may be, might
cause Ancor to be in violation of any such law. Upon written notice from Ancor,
Inrange shall provide such information as Ancor shall reasonably consider
necessary to verify compliance by Inrange with the provisions of this Section
6.4.

      11.3 Indemnification by Inrange. Inrange hereby agrees to indemnify,
defend and hold Ancor harmless from any Legal Action including any reasonable
costs or legal fees thereby incurred by Ancor, (a) that alleges the manufacture,
use or sale of the Inrange Products (other than the Ancor Technology contained
therein), Ancor Products (to the extent modified by Inrange or its agents or
sublicensees), or any of them, infringe any patent, copyright, or trade secret;
or (b) that arises or results from the marketing, distribution, maintenance and
support of the Inrange Products by Inrange (including, without limitation, any
warranties or representations made by Inrange or any of its subdistributors or
agents with respect to such Products or in connection with such activities of
Inrange or any of its subdistributors or agents) or any unfair business practice
of Inrange or any of its subdistributors or agents, except to the extent Ancor
is required to indemnify Inrange pursuant to Section 11.1 above.

      11.4 Indemnification Procedures. The indemnified party shall give written
notice of any Legal Action promptly after its first actual knowledge thereof,
and any failure to give such prompt notice to the indemnifying party shall
terminate the indemnifying party's duty of indemnification hereunder if such
failure to notify promptly materially prejudices the indemnifying party's
ability to defend. The indemnifying party shall have sole and exclusive control
of the defense of any Legal Action, including the choice and direction of any
legal counsel. The indemnified party may not settle or compromise any Legal
Action without the written consent of the indemnifying party.

      11.5 Sole Obligation. THE FOREGOING STATES THE SOLE OBLIGATION AND THE
EXCLUSIVE LIABILITY OF THE PARTIES FOR ANY INFRINGEMENT OR CLAIMS OF

action with respect to any such material breach that cannot be reasonably cured
within thirty (30) days; or

            (c) Ancor may, at its option, terminate this Agreement upon written

Section 12.2 hereof, (i) Ancor shall continue to authorize LSI and its

                                      -21-
<PAGE>   22

      13.1 Dispute Resolution. A party must not start court proceedings (except
proceedings seeking interlocutory relief) in respect of a dispute arising out of
or in connection with this Agreement (in this Section a "Dispute") unless it has
complied with this Section:

      (a) A party claiming that a Dispute has arisen must notify the other party
in writing.

      (b) Within seven days after a notice is given under Section 13.1(a), the
chief executive, managing director or general manager ("Managers") of each party
must meet for the purpose of attempting to resolve the Dispute within a further
seven (7) day period.

      (c) If the Managers of each party are unable to meet or to resolve the
Dispute within the further seven (7) day period, each party must then nominate
in writing to the other party a representative authorized to settle the Dispute
on its behalf.

      (d) Each party must ensure that within a period of twenty (20) days
immediately following the date on which the nomination notice is given under
Section 13.1(c) (or longer period agreed between the parties) its representative
uses his or her reasonable endeavors, with the other representative:

            (i)   to resolve the Dispute; or

            (ii)  to agree on:

                  (a) a process to resolve all or at least part of the Dispute
without court proceedings (e.g., mediation, arbitration, conciliation, executive
appraisal or independent expert determination);

                  (b) the selection and payment of any third party to be engaged
by the parties for, and the involvement of any dispute resolution organization
in, the process;

                  (c) any procedural rules;

resolution of the Dispute. A decision of any third party is not binding on a
party unless that party's representative has so agreed in writing.

      (f) Any information or documents disclosed by a representative under this
Section:


                                      -22-
<PAGE>   23

            (ii)  may not be used except to attempt to settle the Dispute.

      (g) Each party must bear its own costs of resolving a Dispute under this
Section and the parties must bear equally the cost of any third party (e.g.,
mediator, arbitrator) engaged.

      (h) Pending the resolution of any Dispute that is subject to the dispute
resolution process described in this Section 13.1, each party will continue to
perform all of its obligations under this Agreement without prejudice to any
final resolution of the Dispute.

      (i) In the event that a Dispute cannot be settled in accordance with the
foregoing procedure, the parties shall be free to pursue any and all remedies
available to them.

and construed in accordance with, the laws of the State of Minnesota, excluding
its choice of law rules.

14. MISCELLANEOUS

      14.1 Relationship. This Agreement does not make either party the employee,

acquisition, or sale of all or substantially all of the assets of such party
provided that such successor is bound by all of the predecessor's rights and
obligations hereunder. Ancor hereby consents to the proposed acquisition, merger
or consolidation of Inrange and/or its parent, General Signal Corporation, by or

benefit of the parties hereto and their respective permitted assignees. Any

return receipt requested, (b) private courier service, or (c) facsimile
addressed to the respective addresses of the parties as first above written or
at such other addresses as the respective parties may designate by like notice
from time to time. Notices so given shall be effective upon (1) receipt by the

      14.4 Entire Agreement. This Agreement and the Warrant Agreement, including
the Exhibits hereto and thereto which are incorporated herein and therein,
constitute the entire agreement of the parties with respect to the subject
matter hereof and supersede all proposals, oral or written, and all
negotiations, conversations and discussions between the parties.

      14.5 Amendment. This Agreement may not be modified, amended, rescinded,
canceled or waived, in whole or in part, except by written amendment signed by
both parties hereto.

      14.6 Force Majeure. If the performance of this Agreement or any obligation
hereunder (other than the payment of monies due and owing hereunder) is

other than a shortage of money beyond the reasonable control of such party
(including without limitation acts of State or governmental action, riots, war,
prolonged shortage of energy, epidemics, fire, flood, hurricane, typhoon,
earthquake, lightning and explosion, or any refusal or failure of any
governmental authority to grant any export license legally required), the party
so affected shall be excused from such performance, only for so long as and to
the extent that such a force prevents, restricts or interferes with the party's
performance and provided that the party affected gives notice thereof to the
other party and uses diligent efforts to remedy such event or conditions.

such disclosure is required to comply with governmental rules, regulations or
other governmental requirements. In such event, the publishing party shall
furnish a copy of such disclosure to the other party.

      14.9 Severability. If any provision of this Agreement is found
unenforceable under any the laws or regulations applicable thereto, such
provision terms shall be deemed stricken from this Agreement, but such
invalidity or unenforceability shall not invalidate any of the other provisions
of this Agreement.

counterparts, and each such counterpart shall be deemed an original hereof.

      14.11 Waiver. No failure by either party to take any action or assert any

continuation or repetition of the circumstances giving rise to such right
