                           TRADEMARK LICENSE AGREEMENT


   
         This Trademark License Agreement (this "Agreement") is made as of
September 18, 2000, by and between Inrange Technologies Corporation, a Delaware
corporation (the "Company") and SPX Corporation, a Delaware corporation ("SPX").
    

         WHEREAS, SPX is the owner of the trademark and tradename SPX and
registrations and applications therefor in the forms set forth on Schedule A
attached hereto (the "LICENSED TRADEMARK(s)").

         WHEREAS, the Company designs, manufactures, markets and services
networking and switching products for storage networks, data networks and
telecommunications networks and services related to such products (the "COMPANY
BUSINESS").

         WHEREAS, the Company has been an indirect wholly owned subsidiary of
SPX;

         WHEREAS, the Company is issuing shares of Class B Common Stock to the
public in an offering registered under the Securities Act of 1933, as amended,
as contemplated by a registration statement on Form S-1, as supplemented and
amended from time to time (the "IPO"); and

         WHEREAS, following the IPO, the Company desires to continue to use the
LICENSED TRADEMARK(s) in connection with the COMPANY BUSINESS for one year and
SPX is willing to grant to the Company the right to use the LICENSED
TRADEMARK(s) for one year on or in connection with the COMPANY BUSINESS, such
use subject to the terms and conditions of this Agreement.

         NOW THEREFORE, in consideration of the mutual promises and covenants
set forth herein, the parties, intending to be legally bound, hereto agree as
follows:


                          ARTICLE 1 - GRANT OF LICENSE

                1.1 SPX hereby grants to the Company, and the Company hereby
accepts, a non-exclusive, worldwide, royalty-free license to use the LICENSED
TRADEMARK(s) solely in connection with the COMPANY BUSINESS, subject to the
limitations set forth in this Agreement.

                1.2 The grant of license in Section 1.1 above includes the right
by the Company to grant sublicenses within the scope of such license to the
Company's wholly owned subsidiaries, but only for so long as each remains a
wholly owned subsidiary.
   2
                1.3 Except as provided in this Article, all licenses granted
herein shall be nontransferable and nonassignable without the prior written
consent of SPX.


                         ARTICLE 2- OWNERSHIP AND USE OF
                             THE LICENSED TRADEMARKS

                2.1 The Company acknowledges that SPX owns the LICENSED
TRADEMARK(s) and all rights therein and that nothing in this Agreement shall
give the Company any right, title or interest in or to the LICENSED TRADEMARK(s)
other than pursuant to the license granted hereby.

                2.2 The Company agrees that it will do nothing inconsistent with
SPX's ownership of the LICENSED TRADEMARK(s) and shall not claim adversely to
SPX, or assist any third party in attempting to claim adversely to SPX, with
regards to such ownership. The Company agrees that it will not challenge the
title of SPX to the LICENSED TRADEMARK(s), oppose any registration thereof, or
challenge the validity of this Agreement or the licenses granted herein.
Furthermore, the Company will not register, nor attempt to register, any trade
name or trademark which, in whole or in part, incorporates or is confusingly
similar to the LICENSED TRADEMARK(s).

                2.3 Without the prior written approval of SPX, the Company is
not authorized to use the LICENSED TRADEMARK(s) in connection with any business
activity unrelated to the COMPANY BUSINESS.

                2.4 Notwithstanding the license granted herein and any of the
provisions hereof, no rights or licenses are granted to the Company with respect
to any other trademark, service mark, and/or trade name not listed on Schedule A
hereto.

                2.5 The Company agrees to assist SPX in recording this Agreement
with appropriate government authorities where such recording is required by law
or regulation or where such recording is permitted or desired by SPX.

                2.6 All costs associated with recording this Agreement, the
license granted herein and registering, maintaining, or renewing LICENSED
TRADEMARK(S) exclusively used by the Company shall be borne by the Company. All
costs associated with registering, maintaining or renewing any LICENSED
TRADEMARK(S) also used by SPX shall be borne by SPX.


                          ARTICLE 3- QUALITY PROVISIONS

                3.1 The Company agrees that the nature and quality of all

the LICENSED

                                      -2-
   3
TRADEMARK(s) shall conform to the standards set by and under the control of SPX
(hereinafter, "QUALITY STANDARD"). Such QUALITY STANDARD shall be reasonable,
shall be no greater than the quality standards imposed by the Company's
customers in general, and shall be at least equal in quality to the products (in
the aggregate) sold by the Company prior to the date hereof.

                3.2 The Company shall, upon SPX's reasonable request, supply
samples of any products sampled, sold, or otherwise disposed of by the Company
that include the LICENSED TRADEMARK(s) to SPX. Alternatively, SPX may request
the Company to assure that such products conform to the QUALITY STANDARD and, to
this end, the Company shall permit reasonable inspection during business hours
by an authorized representative of SPX of the Company's facilities to inspect
the Company's operations, methods of manufacture, materials used, storage and
packing areas, and the like, associated with the manufacture of products that
include the LICENSED TRADEMARK(s). Any inspections conducted by SPX to ensure
that the QUALITY STANDARD provided herein has been satisfied shall be at the
expense of SPX.

                3.3 The Company shall deliver to SPX, upon SPX's request and
without charge to SPX, representative samples of labels, containers,
advertisements, catalogs, letterhead, and the like, containing the name SPX to
enable SPX to ensure that such name is used only in a manner set forth on
Schedule A.

                3.4 SPX shall have the right to impose on the Company, as
necessary, other specifications or requirements not provided for under this
Article to maintain control over the COMPANY BUSINESS to ensure the requisite
QUALITY STANDARD with respect to products manufactured by the Company that
include the LICENSED TRADEMARK(s).


                 ARTICLE 4- DURATION OF LICENSE AND TERMINATION

                4.1 This Agreement and the license granted herein shall be
effective as of the closing of the IPO, and shall terminate upon the earlier of
(i) one year following the date thereof and (ii) termination pursuant to this
Article 4.

                4.2 In the event that the Company breaches any provision of this
Agreement, including but not limited to failure by the Company to comply with
the QUALITY STANDARD established under Article 3, SPX shall have the right to
terminate the license granted if (i) it has given written notice to the Company
of such breach and (ii) such breach shall be continuing one month from the date
of such notice.

                4.3 SPX shall have the right to immediately terminate this
Agreement, or any or all licenses granted herein, upon written notice to the
Company in the event of a 


                                      -3-
   4
winding-up, sale, consolidation or merger where the Company is not the survivor,
or any sequestration by governmental authority of the Company.

                4.4 Upon the termination of this Agreement, the Company agrees
to (i) promptly discontinue all use of LICENSED TRADEMARK(s) and/or any similar
trade name which contain "SPX" as a part thereof and (ii) promptly take all
steps to refrain from using the LICENSED TRADEMARK(s) in advertising, commercial
registers, directories, internet and web-sites, telephone listings, and all
other similar listings.


                             ARTICLE 5 - PROTECTION

                5.1 The Company shall promptly notify SPX of any and all
infringements, imitations, simulations or other illegal use or misuse of the
LICENSED TRADEMARK(s) which come to the Company's attention. As the sole owner
of the LICENSED TRADEMARK(s), SPX shall determine whether to take any action to
prevent the infringement, imitation, simulation or other illegal use or misuse
of the LICENSED TRADEMARK(s). If SPX elects not to take such action, the Company
may take such action at the Company's expense if it has received SPX's prior
written approval to take such action. In this event, SPX shall, at the Company's
expense, cooperate in such action with the Company including, without
limitation, joining as a party. Any money recovered by way of damages or
otherwise with respect to such action shall be kept by the party which bore the
costs of such action; or, in any case where the parties have shared the costs,
such money shall be shared in proportion to the costs borne by each party.

                5.2 The Company shall render SPX all reasonable assistance in
connection with any matter pertaining to the protection, enforcement or
infringement of LICENSED TRADEMARK(s) used by the Company, whether in the
courts, administrative or quasi-judicial agencies, or otherwise.


                            ARTICLE 6- NEW TRADEMARKS

                6.1 Should the Company desire to develop a trademark using the
name "SPX" in any form other than the LICENSED TRADEMARKS, it must first consult
with and obtain the written approval of SPX, which may be withheld in its sole
discretion. Such newly developed trademarks will be registered in the name of
SPX, and will be deemed to be LICENSED TRADEMARK(s) licensed to the Company
hereunder and will be subject to all of the terms and conditions of this
Agreement. Such approval will not be contingent upon the payment of any fee or
royalties to SPX; however, the cost of obtaining and maintaining such new
trademarks shall be borne solely by the Company.

                                      -4-

                            ARTICLE 7-INDEMNIFICATION

                7.1 The Company agrees to indemnify and hold harmless SPX and
its directors, officers and employees from any and all claims for damage or
injury to persons or property or for loss of life or limb whereby SPX has been
found liable to any third party under any product liability, tort liability or
similar action arising out of or in connection with the use by the Company of
the LICENSED TRADEMARK(s).

                7.2 SPX agrees to indemnify and hold harmless the Company and
its directors, officers and employees from any and all claims of a third party
arising out of or in connection with any claim that the Company's use of the
LICENSED TRADEMARK(s) violates the rights of such third party to such LICENSED
TRADEMARK(s).

companies, affiliates and related entities.

                8.4 Waiver. The waiver by SPX of a breach of any provision

waiver of any subsequent breach of such provision or the waiver of the provision
itself.

                8.5 Injunctive Relief. The Company acknowledges that monetary
relief would not be an adequate remedy for a breach or threatened breach by the

equitable relief, without prejudice to any other rights and remedies that SPX
may have.
