expressly permitted by this Agreement): (a) distributing, copying, duplicating
or otherwise reproducing all or any part of the Packeteer Software, (b)
distributing or using copies of all or any portion of the Packeteer Software
other than as embedded in a royalty-bearing ADC Product, or (c) failing to
ensure that each End User receives a license agreement as required by PARAGRAPH
2.6 ("End User License") will constitute a material breach of this Agreement.

     10.6 GOVERNMENT AGREEMENTS. ADC will take all reasonable steps in making
proposals to and agreements with governments that involve the ADC Product and
related documentation to ensure that Packeteer's proprietary rights receive the
maximum protection available from such governments for commercial computer
software and related documentation developed at private expense.

     10.7 PACKETEER TRADE SECRETS. Packeteer represents that the Packeteer
Software and those techniques, algorithms, and processes contained in the
Packeteer Software which have been developed, acquired or licensed by
Packeteer, or any modification or extraction thereof, constitute trade secrets
of Packeteer and/or its suppliers, and ADC agrees they will be used by ADC only
in accordance with the terms of this Agreement. ADC will take all measures
reasonably required to protect the proprietary rights of Packeteer and its
suppliers in the Packeteer Software Information.

     10.8 ACCESS. In consideration of the licenses and access to proprietary
information and technology of Packeteer granted under this Agreement, ADC
hereby agrees: (a) not to use the Packeteer Software to develop, manufacture or
distribute goods which compete with the Packeteer products ("Competitive
Products"); and (b) to obtain the Packeteer Software only from Packeteer.
Subject to the terms of restrictions on use of proprietary information
(including, but not limited to this PARAGRAPH 10 ("Protection of Proprietary
Rights"), ATTACHMENT D ("Packeteer Trademarks"), and ATTACHMENT E ("Secure
Procedures") provided under this Agreement, this Agreement does not preclude
ADC from independently developing similar technologies or products, where ADC
can demonstrate by competent proof that such independent


                                      10.
<PAGE>   11
development has been created without reference to the Packeteer Software
Source, Packeteer Software Information, or Packeteer Documentation.

11.   TRADEMARKS

      11.1  PROPER USE. Unless ADC or Packeteer opt to terminate the following
requirement of trademark usage and the trademark license of PARAGRAPH 2.5
("Trademark License") under the conditions set out below, ADC will make use of
the Packeteer Trademarks in accordance with the guidelines and requirements set
forth in ATTACHMENT D ("Packeteer Trademarks") and the standard guidelines and
usage requirements as promulgated by Packeteer from time to time regarding the
Trademarks. If Packeteer promulgates any changes to the standard guidelines and
usage requirements, then ADC: (a) shall have six (6) months to continue
operating under the old guidelines; (b) shall have six (6) months to continue
operating under the old guidelines for existing inventory. Either Packeteer or
ADC shall have the right to terminate the trademark usage requirement of this
PARAGRAPH 11.1 ("Proper Use") if ADC does not pay an annual Maintenance Fee as
set out in PARAGRAPH 5.2 ("Annual Maintenance") when such Maintenance Fee is
due. Furthermore, Packeteer shall, under the same instance, additionally be
able to prohibit ADC from using any Packeteer Trademark.

      11.2  RIGHT OF REVIEW. In order to assure the Packeteer Trademarks are
associated only with products and services of Packeteer's high quality
standards, Packeteer will have the right to inspect and review all such
products and services. In the event that any use of the Packeteer Trademark
does not comport with the quality standards set by Packeteer, Packeteer will
advise ADC, and ADC will improve the quality within thirty (30) days so as to
comport with Packeteer's standards or cease use of the Packeteer Trademarks
immediately.

      11.3  NO COMPETITIVE EXPLOITATION OF TRADEMARKS. With respect to any
Competitive Products which ADC develops or markets, ADC agrees that ADC will
not exploit its access to the Packeteer Software, its relationship with
Packeteer, or the existence of the Ported Software to promote Competitive
Products. Furthermore, so long as ADC is marketing the ADC Product under the
Trademarks, ADC agrees to use all reasonable efforts to distinguish the ADC
Product from any Competitive Product when displaying or referring to the ADC
Product in advertisements, catalogs, brochures and at trade shows by (a)
identifying the ADC Product prominently and exclusively with the Trademarks in
such proximity that the viewer is unlikely to associate the ADC Product with the
Competitive Product, and (b) not associating the Trademarks with any
Competitive Product in advertising, press releases, and other promotional and
marketing materials.

12.   CONFIDENTIALITY

      12.1  RESTRICTION ON USE. Except as expressly permitted by this
Agreement, each party ("Recipient"), its employees, and its contractors will
not use in any way for its own account or the account of any third party, nor
disclose to any third party, any Confidential Information revealed to it by the
other party ("Disclosing Party") without the Disclosing Party's prior written
consent; provided, however, that if any Confidential Information of the other
party is required to be disclosed pursuant to any statute, regulation, order,
subpoena or document discovery request, then the Recipient shall provide
written notice thereof to the Disclosing Party as soon as



                                      11.
<PAGE>   12

practicable in order to afford the Disclosing Party an opportunity to seek a
protective order (it being agreed that if the Disclosing Party is unable to
obtain or does not seek a protective order and the Recipient is legally
compelled to disclose such information, disclosure of such information may be
made without liability).

      12.2  DEFINITION OF CONFIDENTIAL INFORMATION. For purposes of this
Agreement, "Confidential Information" consists of (a) any information
designated by the Disclosing party in writing as confidential, (b) the
Packeteer Software Source and the Packeteer Software Information, (c) the
source code and technical documentation for the ADC Product, and (d) the terms
and conditions of this Agreement. Information in oral form will be considered
Confidential Information only to the extent it is (x) identified as
confidential prior to disclosure and (y) summarized in writing and transmitted
to the Recipient, identified as proprietary, within thirty (30) days after the
oral disclosure.

      12.3  EXCLUSIONS FROM DEFINITION OF CONFIDENTIAL INFORMATION.
Confidential Information will not include, and this PARAGRAPH 12
("Confidentiality") will not apply to information that (a) was known to the
Recipient prior to its receipt from the Disclosing Party; (b) is or becomes
public knowledge without fault of Recipient; (c) is acquired by Recipient from
a third party with the right to disclose same and without binder of secrecy;
(d) is independently developed by a party without using the other party's
Confidential Information; or (e) has been approved for release by written
authorization of the Disclosing Party.

      12.4  STANDARD OF CARE. Each party will use the same standard of care
that it applies to its own Confidential Information, but in no event less than
reasonable care. Each party agrees to notify the other promptly in the event of
any breach of confidentiality or security under conditions in which it would
appear that any Confidential Information was prejudiced or exposed to loss, and
will, upon request of the other, take all reasonable steps necessary to recover
any compromised trade secrets disclosed to it or placed in its possession by
virtue of this Agreement. Without limiting the generality of the foregoing, ADC
agrees to comply with the terms of ATTACHMENT E ("Secure Procedures") regarding
the handling of the Packeteer Software.

13.   LIMITATION OF LIABILITY

EXCEPT IN THE CASE OF WILLFULNESS OR GROSS NEGLIGENCE, NEITHER PACKETEER NOR
ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AFFILIATES, OR AGENTS WILL BE LIABLE
TO ADC OR TO ANY THIRD PARTY FOR ANY LOSS OF USE, INTERRUPTION OF BUSINESS, OR
FOR ANY INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOST
PROFITS OR REVENUES) OR SIMILAR DAMAGES, WHETHER BASED ON TORT (INCLUDING
WITHOUT LIMITATION, NEGLIGENCE OR STRICT LIABILITY), CONTRACT, OR OTHER LEGAL
OR EQUITABLE GROUNDS, EVEN IF PACKETEER HAS BEEN ADVISED OR HAD REASON TO KNOW
OF THE POSSIBILITY OF SUCH DAMAGES AND EVEN IN THE EVENT OF FAILURE OF
EXCLUSIVE REMEDIES. In no event will Packeteer's liability under this
Agreement, including claims for contribution or indemnity, exceed the greater
of US $100,000 (One Hundred Thousand Dollars) and all fees paid pursuant to
this Agreement in the twelve (12) months preceding the claim giving rise to
such liability.

authorized in this Agreement, ADC's End Users, and ADC's other direct and
indirect customers of Packeteer Software (collectively "Customers") exercise
the rights expressly granted in PARAGRAPH 2 ("License Grants") to ADC, or which
ADC is authorized to grant to Customers herein, Packeteer will not (a) assert
any Packeteer Patent Right against ADC, (b) assert any Packeteer Patent Right
against Customers, or (c) require any additional fee or royalty from ADC or
Customers based upon any Packeteer Patent Right. Except to the extent of such
covenant not to assert any Packeteer Patent Right, nothing contained herein

license or right with respect to any Packeteer Patent Right.

     15.2 ADC PATENTS. As used herein, "ADC Patent Right" means any patent
right arising under any United States or foreign patent issued or assigned to

<PAGE>   15
date after the inventor had access to the Packeteer Software in which (a) an
inventor is (1) an employee of ADC who has had access to the Packeteer Software
or (2) an independent contractor who has had access to the Packeteer Software
and has assigned patent rights in the claimed invention to ADC and (b) the
Packeteer Software contributed to the claimed invention. ADC Patent Right will
not include any patent applications filed three (3) years after termination or
expiration of this Agreement. ADC covenants that it will not (a) assert any ADC
Patent Right against Packeteer or against its sublicensees or customers for
products of a similar nature to that distributed by ADC, or (b) require any fee
or royalty from Packeteer or such sublicensees or customers for the sale of
such products based upon ADC Patent Rights. Except to the extent expressed
above, nothing contained herein will be construed as conferring, by

16.  GENERAL

     16.1 GOVERNING LAW. This Agreement will be governed in all respects by the
laws of the United States of America and the State of California as such laws
are applied to agreements entered into and to be performed entirely within
California between California residents. The parties agree that the United
Nations convention on Contracts for the International Sale of Goods is
specifically excluded from application to this Agreement.

     16.2 GOVERNING LANGUAGE. This governing language and any interpretation or
construction of this Agreement will be English.

     16.3 FORUM. All disputes arising under this Agreement may be brought in
the state and federal courts located in San Jose, California, or Minneapolis,
Minnesota as permitted by law. ADC and Packeteer consent to the personal
jurisdiction of the above courts.

     16.4 NOTICES. All notices or reports permitted or required under this
Agreement will be in writing and will be delivered by personal delivery,
telegram, telex, telecopier, facsimile transmission, or by certified or
registered mail, return receipt requested, and will be deemed given upon
personal delivery, five (5) days after deposit in the mail, or upon
acknowledgment of receipt of electronic transmission. Notices will be sent to
the addresses set forth in the introductory paragraph of this Agreement and
shall be sent to the attention of the Chief Financial Officer, or to such other
address or person as may be designated in writing.

     16.5 INJUNCTIVE RELIEF. It is understood and agreed that, notwithstanding
any other provisions of this Agreement, breach of the provisions of this
Agreement relating to the protection of intellectual property rights
(including, but not limited to, PARAGRAPHS 2 ("License Grants"), 10
("Protection of Proprietary Rights"), 11 ("Trademarks"), 12
("Confidentiality"), ATTACHMENT D ("Packeteer Trademarks"), and ATTACHMENT E
("Secure Procedures") may cause the other party irreparable damage for which
recovery of money damages would be inadequate, and that a party will therefore
be entitled to obtain timely injunctive relief (whether by arbitral or judicial
authority) to protect its rights under this Agreement in addition to any and
all remedies available at law.

     16.6 NO AGENCY. Nothing contained herein will be construed as creating any
agency, partnership, or other form of joint enterprise between the parties.




                                      15.
<PAGE>   16
     16.7 FORCE MAJEURE. Neither party will be liable hereunder by reason of
any failure or delay in the performance of its obligations hereunder (except for
the payment of money) on account of strikes, shortages, riots, insurrection,
fires, flood, storm, explosions, acts of God, war, governmental action, labor
conditions, earthquakes, material shortages or any other cause which is beyond
the reasonable control of such party.

     16.8 WAIVER. The failure of either party to require performance by the
other party of any provision hereof will not affect the full right to require
such performance at any time thereafter; nor will the waiver by either party of
a breach of any provision hereof be taken or held to be a waiver of the
provision itself.

     16.9 SEVERABILITY. In the event that any provision of this Agreement will
be unenforceable or invalid under any applicable law or be so held by applicable
court decision, such unenforceability or invalidity will not render this
Agreement unenforceable or invalid as a whole, and, in such event, such
provision will be changed and interpreted so as to best accomplish the
objectives of such unenforceable or invalid provision within the limits of
applicable law or applicable decisions.

     16.10 HEADINGS. The Paragraph headings appearing in this Agreement are
inserted only as a matter of convenience and in no way define, limit, construe,
or describe the scope or extent of such Paragraph or in any way affect this
Agreement.

     16.11 ASSIGNMENT. Neither this Agreement nor any rights or obligations of
ADC hereunder may be assigned or transferred by ADC in whole or in part, whether
by operation of law or otherwise, without the prior written approval of
Packeteer which shall not unreasonably be withheld. For the purposes of this
Paragraph, a change in ownership or sale of substantially all of the assets of
ADC or the business division of ADC primarily involved in this Agreement shall
not be considered an assignment or transfer of ADC's rights. Packeteer may
exercise full transfer and assignment rights in any manner at Packeteer's
discretion and specifically may sell, pledge, or otherwise transfer its right to
receive royalties under this Agreement.

     16.12 EXPORT. ADC acknowledges that the laws and regulations of the United
States restrict the export and re-export of commodities and technical data of
United States origin, including the Packeteer Software licensed hereunder. ADC
agrees that it will not export or re-export the Packeteer Software or ADC
Product in any form, without the appropriate United States and foreign
governmental licenses, if legally required. ADC agrees that its obligations
pursuant to this Paragraph will survive and continue after any termination or
expiration of rights under this Agreement.

     16.13 FULL POWER. Each party warrants that it has full power to enter into
and perform this Agreement, and the person signing this Agreement on each
party's behalf has been duly authorized and empowered to enter into this
Agreement. Each party further acknowledges that it has read this Agreement,
understands it and agrees to be bound by it.

     16.14 ENTIRE AGREEMENT. This Agreement together with the Attachments and
appendices completely and exclusively states the agreement of the parties
regarding its subject matter. If supersedes, and its terms govern, all prior
proposals, agreements, or other



                                      16.

<PAGE>   17
communications between the parties, oral or written, regarding such subject
matter. This Agreement will not be modified except by a subsequently dated
written amendment signed on behalf of all parties by their duly authorized
representative and any provision of a purchase order purporting to supplement
or vary the provisions hereof will be void.

     16.15  COUNTERPARTS. This Agreement may be executed simultaneously in two
or more counterparts, each of which will be considered an original, but all of
which together will constitute one and the same instrument.

     IN WITNESS WHEREOF, the parties hereof have caused this OEM Agreement to
be executed by their duly authorized representatives as of the Effective Date.

                      PACKETEER END USER LICENSE AGREEMENT

The following is a sample form of the Packeteer End User Agreement as of the
Effective Date:

    "THIS AGREEMENT IS PROOF OF YOUR RIGHT TO USE THE SOFTWARE CONTAINED IN
    THE PACKETEER PACKETSHAPER PRODUCT AND CONTAINS ADDITIONAL INFORMATION
     CONCERNING PACKETEER'S PRODUCT WARRANTY AND LIMITATIONS OF LIABILITY.
                           PLEASE READ IT CAREFULLY.

This Agreement is between you (either an individual or an entity) and
PACKETEER, INC. ("Packeteer"). Packeteer is willing to grant you the following
rights to use the software incorporated in or supplied with the Packeteer
PacketShaper product and its accompanying documentation (collectively, the
"Packeteer Software") only if you agree to be bound by all of the terms of this
Agreement. By installing the product (the "Equipment") or using the Packeteer
Software, you agree to be bound by all the terms of this Agreement. If you do
not agree to be bound by any of the terms of this Agreement, Packeteer is
unwilling to grant you any rights to use the Packeteer Software and you must
not use the Packeteer Software or the Equipment; instead you must promptly
return the Equipment and Packeteer Software for a full refund to Packeteer or
to the authorized Packeteer reseller that provided you with the product.

1.   OWNERSHIP: The Packeteer Software is and shall remain a proprietary
product of Packeteer. Packeteer and Packeteer's suppliers shall retain
ownership of all patents, copyrights, trademarks, trade names, trade secrets
and other proprietary rights relating to or residing in the Packeteer Software
and Equipment. Except for the license grant provided in Paragraph 2, you shall
have no right, title or interest in or to the Packeteer Software. The Packeteer
Software is licensed, not sold, to you for use only under the terms of this
Agreement.

2.   GRANT OF LICENSE: Packeteer grants you a non-transferable (except as set
forth in this Paragraph) non-exclusive, restricted right to use the Packeteer
Software as incorporated in or supplied with the Equipment and solely in
connection with the operation of the Equipment for your own internal business
purposes. You understand that Packeteer may update the Packeteer Software at
any time and in doing so incurs no obligation to furnish such updates to you
pursuant to this Agreement. You may transfer the license to use the Packeteer
Software only in connection with a sale or transfer of the Equipment and as
included with the Equipment and not on a standalone basis, provided the buyer
or transferee agrees to be bound by the terms and conditions of this Agreement.

3.   RESTRICTIONS: Packeteer reserves all rights in the Packeteer Software not
expressly granted to you. Except as permitted in Paragraph 2, you may not use,
copy, modify, create derivative works of, distribute, sell, assign, pledge,
sublicense, lease, loan, rent, timeshare, deliver or otherwise transfer the
Packeteer Software, nor permit any other party to do any of the foregoing. You
may not remove from the Packeteer Software, or alter, any of the trademarks,
trade names, logos, patent or copyright notices or markings, or add any other
notices or markings to the Packeteer Software. To the extent permissible by
applicable law, you may not derive or attempt to derive the source code of the
Packeteer Software by any means, nor permit any other party to derive or
attempt to derive such source code. To the extent permissible by applicable
law, you may not reverse engineer, decompile, disassemble, or translate the
Packeteer Software or any part thereof.

4.   LIMITED WARRANTY: Packeteer does not warrant that the functions contained
in the Packeteer Software and Equipment will meet your requirements or that the
operation of your Packeteer Software or Equipment will be uninterrupted or
error free. Packeteer warrants that for a period of ninety (90) days from your
date of receipt of the Equipment and Packeteer Software, (a) the Equipment will
be free of any defects in materials and workmanship and (b) the Packeteer
Software will perform substantially in accordance with the accompanying
documentation. This limited warranty is void if failure of the Equipment or
Packeteer Software to conform with the warranty has resulted from improper
installation, testing, misuse, neglect, accident, fire or other hazard, or any
breach of this Agreement.

5.   LIMITED REMEDIES: In the event of a breach of the foregoing limited
warranty, you must return the Equipment and Packeteer Software to Packeteer or
the Packeteer authorized reseller that provided you with the Packeteer
Software, postage prepaid, before the expiration of the warranty period, with a
copy of the invoice for the unit. Packeteer's sole and exclusive obligation and
your sole and exclusive remedy shall be, at Packeteer's sole discretion, to
either (a) repair the Packeteer Software or Equipment; (b) provide a
replacement unit or a replacement copy of the Packeteer Software or (c) refund
the amount you paid for the unit and terminate this Agreement. Any replacement
copy of the Packeteer Software or replacement Equipment unit will be warranted
for the remainder of the original warranty period or thirty (30) days,
whichever is longer.

6.   NO OTHER WARRANTIES: OTHER THAN THE FOREGOING LIMITED WARRANTY, PACKETEER
HEREBY EXPRESSLY DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
WITHOUT LIMITATION THE IMPLIED WARRANTIES OF TITLE, NON-INFRINGEMENT, FITNESS
FOR A PARTICULAR PURPOSE AND MERCHANTABILITY. SOME JURISDICTIONS DO NOT ALLOW

Packeteer may adopt certain trademarks, trade names, marks, and logos
("Trademarks") from time to time in its sole discretion. The following
Packeteer Trademarks are licensed to ADC pursuant to this Agreement:

                             [PACKETEER INC. LOGO]

The above trademark is designated to be included on the front panel of the
ServicePoint product(s). Pending platform(s) design, this trademark use will be

Trademarks in Packeteer. ADC agrees that it will do nothing inconsistent with
such ownership and that all use of the Trademarks by ADC will inure to the
benefit of and be on behalf of Packeteer. ADC acknowledges that Trademarks are
valid under applicable law and that ADC's utilization of the Trademarks will
not create any right, title or interest in or to such Trademarks. ADC
acknowledges Packeteer's exclusive right to use of the Trademarks and agrees
not to do anything contesting or impairing the trademark rights of the
Packeteer. Any use of the Trademarks must identify Packeteer as the owner of
such Trademarks.

2.   QUALITY STANDARDS. Packeteer hereby appoints ADC as its representative for
the limited purpose of controlling the quality of the ADC Products and any
other products or services it supplies in connection with the use of the
Trademarks. ADC agrees that (a) the nature and quality of the ADC Products and
any other products or services it supplies in connection with use of the
Trademarks will conform to the standards set by Packeteer, and (b) it will
cooperate with Packeteer in facilitating Packeteer's monitoring and control of
the nature and quality of such products and services. Such assistance will
include supplying Packeteer, upon its request, with specimens of its use of the
Trademarks, including supplying samples of reprinted documentation,
translations, product packaging and promotional materials that use the
Trademarks in conjunction with ADC's marketing of ADC Products. Upon reasonable
notice to ADC and at Packeteer's sole expense, Packeteer may conduct an
inspection of such specimens at facilities of its choosing to determine
conformance with the standards. ADC will, at Packeteer's request and expense,
assist Packeteer in conducting such inspection and testing including, but not
limited to, providing Packeteer with applicable hardware. If, at any time,
Packeteer determines that ADC has not met the Packeteer quality standards,
Packeteer will so advise ADC and, upon ADC's receipt of such notice by any
means, ADC will have thirty (30) days to improve the quality to the standard
previously approved by Packeteer, or to cease the use of all Trademarks.



                                      D-1.

<PAGE>   23
ADC will comply with all applicable laws and regulations pertaining to the use
of the Trademarks and to the distribution and advertising of the ADC Products;
however, Packeteer shall obtain all appropriate government approvals pertaining
to the use of the Trademarks.

3.   INFRINGEMENT PROCEEDINGS. ADC agrees to notify Packeteer of any
unauthorized use of the Trademarks by others promptly as it comes to ADC's
attention. Packeteer will have the sole right and discretion to bring
infringement or unfair competition proceedings involving the Trademarks.

4.   ADC'S USE OF TRADEMARKS. Except as set forth otherwise in the Agreement,
ADC agrees that it will (a) prominently and permanently include the Packeteer
Trademarks on all copies of the Packeteer Software and on any ADC Products
distributed to End Users (b) use the Packeteer Trademarks, including the
Packeteer logo, in any advertising or printed materials concerning the ADC
Products, (c) use all applicable Trademarks on all copies, advertisements,
brochures, manuals, packaging and other appropriate uses made in the promotion,
sale or use of the ADC Products, and (d) ensure that the logo set forth above
will appear prominently on the logon screen, splash screen, or other first
display created by the Packeteer Software when End Users initialize the
Packeteer Software.

5.   TRADEMARK REGISTRATIONS. ADC, at Packeteer's request and expense, will (a)
promptly provide Packeteer with any specimens, (b) execute all applications for
trademark registrations, assignments or other applicable documents, and (c)
perform any other act reasonably necessary for Packeteer to secure or maintain
any and all trademark rights in any country in which ADC is marketing the ADC
Products in association with a Trademark. ADC's responsibilities will include
complying with the formalities of local law, including, but not limited to,
executing any application for registration as a registered user, executing
additional license agreements suitable for recording with the appropriate
authorities or providing proof of use of the trademarks in any other applicable
documents.

6.   NO UNITARY OR COMPOSITE TRADEMARKS. ADC agrees not to use any other
trademark or service mark in close proximity to any of the Packeteer Trademarks
or combine the marks so as to effectively create a unitary composite mark
without the prior written approval of Packeteer.

                                  ATTACHMENT E

                               SECURE PROCEDURES


     1.  AUTHORIZED EMPLOYEES AND CONTRACTORS. ADC agrees that it will not
disclose all or any portion of the Packeteer Software to third parties, with the
exception of authorized employees ("Authorized Employees") and authorized
contractors ("Authorized Contractors") (subject to ADC's having obtained
authorization for use of such contractors in accordance with PARAGRAPH 2 of this
ATTACHMENT E, below) who (a) require access thereto for a purpose authorized by
this Agreement, (b) have signed an employee or contractor agreement in which
such employee or contractor agrees to protect third party confidential
information and (c) in the case of disclosure of Packeteer Software Source or
Packeteer Software Information ("Source Information"), have received a notice of
confidentiality prior to access to such Source Information, and again upon any
termination of such access, that contains, at a minimum provisions substantially
in accordance with the following:

     "Recipient has previously signed an agreement with ADC pursuant to which
     Recipient has agreed to maintain the confidentiality of confidential
     information of ADC and its suppliers (the "Confidential Information") and
     to use the Confidential Information solely for ADC's benefit. The purpose
     of this notice is to apprise Recipient that Recipient will be receiving
     certain proprietary information of Packeteer, including internal source
     code, interface specifications and related documentation for the Packeteer
     product and related Packeteer information, all of which is of a
     confidential nature and which contains valuable trade secrets, known-how,
     and proprietary information of Packeteer (the "Packeteer Information") and
     which constitutes Confidential Information under Recipient's agreement with
     ADC.

     This is to inform Recipient that the Packeteer Information cannot be used
     for any purpose except for the specific purposes which ADC or Packeteer
     authorize in writing and that Recipient is not authorized to disclose the
     Packeteer Information to any person at any time except to employees of
     Packeteer and to those Authorized Employees and Authorized Contractors
     which ADC informs Recipient are authorized to receive such Packeteer
     Information.

     All materials including, without limitation, programs, recorded
     information, documents, drawings, models, apparatus, sketches, designs, and
     lists furnished to Recipient by ADC or Packeteer which are designated in
     writing to be the property of Packeteer remain the property of Packeteer
     and must be returned to Packeteer promptly at its request, together with
     any copies or modifications thereof."

ADC guarantees the compliance of all such Authorized Employees and Authorized
Contractors with their obligations under such confidentiality agreements.

     2.  PRIOR APPROVAL OF CONTRACTORS. Notwithstanding the provisions in this
ATTACHMENT E permitting Authorized Contractors to have access to Source
Information, ADC may not permit a contractor to come into contact with Source
Information, or engage in the


                                      E-1.
<PAGE>   25
development of the Ported Software hereunder unless ADC has first obtained such
authorization in writing from Packeteer. Packeteer, in its sole discretion, may
withhold such approval in the event that a contractor (or contractor's
employer) to whom ADC intends to disclose Source Information is engaged in
Competitive Product development, either for its own benefit or for the benefit
of a third party, or if Packeteer believes that the contractor may be engaged
in similar product development, and ADC cannot assure Packeteer to its
satisfaction that contractor, while engaged in supporting such development
activities, will be able to refrain from commingling or sharing any portion of
the Source Information with any such Competitive Product development.

     3.   PACKETEER SUPPORT INFORMATION.

          3.1  ADC will ensure that all Source Information received from
Packeteer, and copies made thereof, will be properly marked or otherwise
appropriately identified as Packeteer Information before being made available
to Authorized Employees and Authorized Contractors hereunder.

          3.2  ADC will ensure that the same degree of care is used to prevent
the unauthorized use, dissemination, or publication of the Source Information
as ADC uses to protect its own confidential information of a like nature, but
in no event will the safeguards for protecting such Packeteer Support
Information be less than a reasonably prudent business would exercise under
similar circumstances. ADC will take prompt and appropriate action to prevent
unauthorized use or disclosure of Source Information.

          3.3  ADC will instruct Authorized Employees and Authorized
contractors not to copy Source Information on their own, and not to disclose
Source Information to any one not authorized to receive it.

          3.4  Source Information will be handled, used, and stored solely at
the Development Site. The Source Information will not be stored on any computer
or network which is accessible from outside of the Development Site or by
people other than Authorized Employees or Authorized Contractors.

          3.5  ADC will provide Packeteer with a log of all Authorized
Employees and Authorized Contractors who have access to the Source Information
and who have had access in the preceding five (5) years.

     4.   TRADE SECRETS. The Packeteer Software, including the techniques,
algorithms, and processes contained in the Packeteer Software which have been
developed, acquired, or licensed by Packeteer, or any modification or
extraction thereof, constitute trade secrets of Packeteer and/or its suppliers,
and will be used by ADC only in accordance with the terms of this Agreement. ADC
will take all measures reasonably required to protect the proprietary rights of
Packeteer and its suppliers in the Packeteer Software and will promptly notify
Packeteer of any lost or missing items and take all reasonable steps to recover
such items. ADC agrees that it will not attempt to reverse engineer any portion
of the Packeteer Software which is provided to ADC solely in object code form.

     5.   NO COMMINGLING OF TECHNOLOGY. If ADC engages in development of
products (other than the Ported Software) that are comparable to the Packeteer
Software

                                      E-2.








<PAGE>   26
("Comparable Products") during the term of this Agreement, it will ensure that
there is no sharing with such Comparable Products development any of the
following: (a) design documents of schematics supplied by Packeteer; (b) Source
Information or other information based upon or derived from the Source
Information; or (c) any computing resources (including, but not limited to,
computer systems and network storage devices), or (d) personnel with access to
any of (a)-(c) above. ADC will ensure that all Authorized Employees and
Authorized Contractors who have had previous access to the Packeteer Software
will be precluded for a period of twenty-four (24) months after their latest
access to such Packeteer Software from being employed in any Comparable Product
development (either internally or externally) by or for ADC or any Competitive
Product (as defined in PARAGRAPH 10.8 ("Access") of this Agreement) or
Comparable Product development for any third parties. "Employment in any
Competitive (or Comparable) Product development" will be defined as having
direct access to, or producing any specifications, documentation, or source
code, for components of a Competitive (or Comparable) Product.

     6.   PROPRIETARY RIGHTS AUDIT. During the term of the Agreement and for a
period of twenty-four (24) months thereafter, an independent auditor selected
by Packeteer will have access to such portion of ADC's records and premises to
allow Packeteer to determine whether ADC is substantially in compliance with
this ATTACHMENT E and PARAGRAPH 10 ("Protection of Proprietary Rights") of the
Agreement. In no event will audits be made hereunder more frequently than twice
per year. Such access will be (a) during ADC's regular business hours, (b)
arranged so that, to the extent possible, ADC's regular business activities are
minimally disrupted and (c) under the terms of an appropriate confidentiality
agreement executed by the individual(s) conducting such audit. ADC will
immediately correct any deficiencies discovered in the course of the audit.

exceeds the minimum quarterly royalty obligation payable for such quarter, ADC
shall remit the additional royalties due along with the other quarterly
payments for such quarter.

References to calendar quarters and year periods for the royalty obligations
(but not the maintenance payments) set forth in Section I above are measured
from the FCS Date.
