                             AND SECURITY AGREEMENT

         This Collateral Assignment, Patent Mortgage and Security Agreement is
made as of December 5, 2001 by and between Viseon, Inc. ("Assignor"), and
Silicon Valley Bank, a California banking corporation ("Assignee").

                                    RECITALS

         A. Assignee has agreed to lend to Assignor certain funds (the "Loans"),
pursuant to a Loan and Security Agreement dated December 5, 2001 (the "Loan
Agreement") and Assignor desires to borrow such funds from Assignee.

         B. In order to induce Assignee to make the Loans, Assignor has agreed
to assign certain intangible property to Assignee for purposes of securing the
obligations of Assignor to Assignee.

         NOW, THEREFORE, THE PARTIES HERETO AGREE AS FOLLOWS:

         1. Assignment, Patent Mortgage and Grant of Security Interest. As
collateral security for the prompt and complete payment and performance of all
of Assignor's present or future indebtedness, obligations and liabilities to
Assignee, Assignor hereby assigns, transfers, conveys and grants a security
interest and mortgage to Assignee, as security, but not as an ownership
interest, in and to Assignor's entire right, title and interest in, to and under
the following (all of which shall collectively be called the "Collateral"):

                  (a) All of present and future United States registered
copyrights and copyright registrations, including, without limitation, the
registered copyrights listed in Exhibit A-1 to this Agreement (and including all
of the exclusive rights afforded a copyright registrant in the United States
under 17 U.S.C. ss.106 and any exclusive rights which may in the future arise by
act of Congress or otherwise) and all present and future applications for
copyright registrations (including applications for copyright registrations of

and any and all royalties, payments, and other amounts payable to Assignor in
connection with the Registered Copyrights, together with all renewals and
extensions of the Registered Copyrights, the right to recover for all past,
present, and future infringements of the Registered Copyrights, and all computer
programs, computer databases, computer program flow diagrams, source codes,
object codes and all tangible property embodying or incorporating the Registered
Copyrights, and all other rights of every kind whatsoever accruing thereunder or
pertaining thereto.

                  (b) All present and future copyrights which are not registered
in the United States Copyright Office (the "Unregistered Copyrights"), whether
now owned or hereafter acquired, including without limitation the Unregistered
Copyrights listed in Exhibit A-2 to this Agreement, and any and all royalties,
payments, and other amounts payable to Assignor in connection with the
Unregistered Copyrights, together with all renewals and extensions of the
Unregistered Copyrights, the right to recover for all past, present, and future
infringements of the Unregistered Copyrights, and all computer programs,
computer databases, computer program flow diagrams, source codes, object codes
and all tangible property embodying or incorporating the Unregistered
Copyrights, and all other rights of every kind whatsoever accruing thereunder or
pertaining thereto. The Registered Copyrights and the Unregistered Copyrights
collectively are referred to herein as the "Copyrights."

Agreement (the "Licenses").

                  (g) All patents, patent applications and like protections
including, without limitation, improvements, divisions, continuations, renewals,
reissues, extensions and continuations-in-part of the same, including without
limitation the patents and patent applications set forth on Exhibit B attached
hereto (collectively, the "Patents");

                  (h) Any trademark and servicemark rights, whether registered
or not, applications to register and registrations of the same and like
protections, and the entire goodwill of the business of Assignor connected with
and symbolized by such trademarks, including without limitation those set forth
on Exhibit C attached hereto (collectively, the "Trademarks")

                  (i) Any and all claims for damages by way of past, present and
future infringements of any of the rights included above, with the right, but
not the obligation, to sue for and collect such damages for said use or
infringement of the intellectual property rights identified above;

                  (j) All licenses or other rights to use any of the Copyrights,

without limitation all payments under insurance or any indemnity or warranty
payable in respect of any of the foregoing.

OBLIGATIONS TO ASSIGNEE UNDER THE LOAN AGREEMENT.

         2. Authorization and Request. Assignor authorizes and requests that the
Register of Copyrights and the Commissioner of Patents and Trademarks record
this conditional assignment.

         3. Covenants and Warranties. Assignor represents, warrants, covenants
and agrees as follows:

                  (a) Assignor is now the sole owner of the Collateral, except
for non-exclusive licenses granted by Assignor to its customers in the ordinary
course of business.

                  (b) Listed on Exhibits A-1 and A-2 are all copyrights owned by
Assignor, in which Assignor has an interest, or which are used in Assignor's
business.

                  (c) Each employee, agent and/or independent contractor who has
participated in the creation of the property constituting the Collateral has
either executed an assignment of his or her rights of authorship to Assignor or
is an employee* of Assignor acting within the scope of his or her employment and
was such an employee at the time of said creation.

                  *, OR WAS AN EMPLOYEE,

                  (d) All of Assignor's present and future software, computer
programs and other works of authorship subject to United States copyright
protection, the sale, licensing or other disposition of which results in
royalties receivable, license fees receivable, accounts receivable or other sums
owing to Assignor (collectively, "Receivables"), have been and shall be
registered* with the United States Copyright Office prior to the date Assignor
requests or accepts any loan from Assignee with respect to such Receivables and
prior to the date Assignor includes any such Receivables in any accounts
receivable aging, borrowing base report or certificate or other similar report
provided to Assignee, and Assignor shall provide to Assignee copies of all such
registrations** promptly upon the receipt of the same.

*, OR APPLICATION FOR SUCH REGISTRATION HAS BEEN OR SHALL BE MADE,

**, AND RECEIPTS OR OTHER EVIDENCE OF THE APPLICATIONS THEREOF,

                  (e) Assignor shall undertake all reasonable measures to cause
its employees, agents and independent contractors to assign to Assignor all
rights of authorship to any copyrighted material in which Assignor has or may
subsequently acquire any right or interest.

                  (f) Performance of this Assignment does not conflict with or
result in a breach of any agreement to which Assignor is bound, except to the
extent that certain intellectual property agreements prohibit the assignment of
the rights thereunder to a third party without the licensor's or other party's
consent and this Assignment constitutes an assignment.

                  (g) During the term of this Agreement, Assignor will not
transfer or otherwise encumber any interest in the Collateral, except for
non-exclusive licenses granted by Assignor in the ordinary course of business or
as set forth in this Assignment;

                  (h) Each of the Patents is* valid and enforceable, and no part
of the Collateral has been judged invalid or unenforceable, in whole or in part,
and no claim has been made that any part of the Collateral violates the rights
of any third party;

                                      -3-
<PAGE>

*, TO THE BEST OF ASSIGNOR'S KNOWLEDGE,

                  (i) Assignor shall promptly advise Assignee of any material
adverse change in the composition of the Collateral, including but not limited
to any subsequent ownership right of the Assignor in or to any Trademark, Patent
or Copyright not specified in this Assignment;

                  (j) Assignor shall (i) protect, defend and maintain the
validity and enforceability of the Trademarks, Patents and Copyrights, (ii) use
its best efforts to detect infringements of the Trademarks, Patents and
Copyrights and promptly advise Assignee in writing of material infringements
detected and (iii) not allow any Trademarks, Patents, or Copyrights to be
abandoned, forfeited or dedicated to the public without the written consent of
Assignee, which shall not be unreasonably withheld unless Assignor determines
that reasonable business practices suggest that abandonment is appropriate.

                  (k) Assignor shall promptly* register the most recent version
of any of Assignor's Copyrights, if not so already registered, and shall, from
time to time, execute and file such other instruments, and take such further
actions as Assignee may reasonably request from time to time to perfect or
continue the perfection of Assignee's interest in the Collateral;

*MAKE APPLICATION TO

                  (l) This Assignment creates, and in the case of after acquired
Collateral, this Assignment will create at the time Assignor first has rights in
such after acquired Collateral, in favor of Assignee a valid and perfected first
priority security interest in the Collateral in the United States securing the
payment and performance of the obligations evidenced by the Loan Agreement upon
making the filings referred to in clause (m) below;

                  (m) To its knowledge, except for, and upon, the filing with
the United States Patent and Trademark office with respect to the Patents and
Trademarks and the Register of Copyrights with respect to the Copyrights
necessary to perfect the security interests and assignment created hereunder and
except as has been already made or obtained, no authorization, approval or other
action by, and no notice to or filing with, any U.S. governmental authority or
U.S. regulatory body is required either (i) for the grant by Assignor of the
security interest granted hereby or for the execution, delivery or performance
of this Assignment by Assignor in the U.S. or (ii) for the perfection in the
United States or the exercise by Assignee of its rights and remedies thereunder;

                  (n) All information heretofore, herein or hereafter supplied
to Assignee by or on behalf of Assignor with respect to the Collateral is
accurate and complete in all material respects.

                  (o) Assignor shall not enter into any agreement that would
materially impair or conflict with Assignor's obligations hereunder without
Assignee's prior written consent, which consent shall not be unreasonably
withheld. Assignor shall not permit the inclusion in any material contract to
which it becomes a party of any provisions that could or might in any way
prevent the creation of a security interest in Assignor's rights and interest in
any property included within the definition of the Collateral acquired under
such contracts, except that certain contracts may contain anti-assignment
provisions that could in effect prohibit the creation of a security interest in
such contracts.

                                      -4-
<PAGE>

                  (p) Upon any executive officer of Assignor obtaining actual
knowledge thereof, Assignor will promptly notify Assignee in writing of any
event that materially adversely affects the value of any material Collateral,
the ability of Assignor to dispose of any material Collateral or the rights and
remedies of Assignee in relation thereto, including the levy of any legal
process against any of the Collateral.

         4. Assignee's Rights. Assignee shall have the right, but not the
obligation, to take, at Assignor's sole expense, any actions that Assignor is
required under this Assignment to take but which Assignor fails to take, after
fifteen (15) days' notice to Assignor. Assignor shall reimburse and indemnify
Assignee for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this section 4.

         5. Inspection Rights. Assignor hereby grants to Assignee and its
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable written notice to Assignor, and any of Assignor's
plants and facilities that manufacture, install or store products (or that have
done so during the prior six-month period) that are sold utilizing any of the
Collateral, and to inspect the products and quality control records relating
thereto upon reasonable written notice to Assignor and as often as may be
reasonably requested, but not more than one (1) in every six (6) months;
provided, however, nothing herein shall entitle Assignee access to Assignor's
trade secrets and other proprietary information.

         6. Further Assurances; Attorney in Fact.

                  (a) Assignor will, subject to any prior licenses, encumbrances
and restrictions and prospective licenses, make, execute, acknowledge and
deliver, and file and record in the proper filing and recording places in the
United States, all such instruments, including, appropriate financing and
continuation statements and collateral agreements and filings with the United
States Patent and Trademarks Office and the Register of Copyrights, and take all
such action as may reasonably be deemed necessary or advisable, or as requested
by Assignee, to perfect Assignee's security interest in all Copyrights, Patents
and Trademarks and otherwise to carry out the intent and purposes of this
Collateral Assignment, or for assuring and confirming to Assignee the grant or
perfection of a security interest in all Collateral.

                  (b) Upon an Event of Default, Assignor hereby irrevocably
appoints Assignee as Assignor's attorney-in-fact, with full authority in the
place and stead of Assignor and in the name of Assignor, Assignee or otherwise,
from time to time in Assignee's discretion, upon Assignor's failure or inability
to do so, to take any action and to execute any instrument which Assignee may
deem necessary or advisable to accomplish the purposes of this Collateral
Assignment, including:

                           (i) To modify, in its sole discretion, this
Collateral Assignment without first obtaining Assignor's approval of or
signature to such modification by amending Exhibit A-1, Exhibit A-2, Exhibit
A-3, Exhibit B and Exhibit C, thereof, as appropriate, to include reference to
any right, title or interest in any Copyrights, Patents or Trademarks acquired
by Assignor after the execution hereof or to delete any reference to any right,
title or interest in any Copyrights, Patents or Trademarks in which Assignor no
longer has or claims any right, title or interest; and

                                      -5-
<PAGE>

                           (ii) To file, in its sole discretion, one or more
financing or continuation statements and amendments thereto, relative to any of
the Collateral without the signature of Assignor where permitted by law.

         7. Events of Default. The occurrence of any of the following shall
constitute an Event of Default under the Assignment:

                  (a) An Event of Default occurs under the Loan Agreement; or

                  (b) Assignor breaches any warranty or agreement made by
Assignor in this Assignment.

         8. Remedies. Upon the occurrence and continuance of an Event of
Default, Assignee shall have the right to exercise all the remedies of a secured
party under the California Uniform Commercial Code, including without limitation
the right to require Assignor to assemble the Collateral and any tangible
property in which Assignee has a security interest and to make it available to
Assignee at a place designated by Assignee. Assignee shall have a nonexclusive,
royalty free license to use the Copyrights, Patents and Trademarks to the extent
reasonably necessary to permit Assignee to exercise its rights and remedies upon
the occurrence of an Event of Default. Assignor will pay any expenses (including
reasonable attorney's fees) incurred by Assignee in connection with the exercise
of any of Assignee's rights hereunder, including without limitation any expense
incurred in disposing of the Collateral. All of Assignee's rights and remedies
with respect to the Collateral shall be cumulative.

         9. Indemnity. Assignor agrees to defend, indemnify and hold harmless
Assignee and its officers, employees, and agents against: (a) all obligations,
demands, claims, and liabilities claimed or asserted by any other party in
connection with the transactions contemplated by this Agreement, and (b) all
losses or expenses in any way suffered, incurred, or paid by Assignee as a
result of or in any way arising out of, following or consequential to
transactions between Assignee and Assignor, whether under this Assignment or
otherwise (including without limitation, reasonable attorneys fees and
reasonable expenses), except for losses arising form or out of Assignee's gross
negligence or willful misconduct.

         10. Release. At such time as Assignor shall completely satisfy all of
the obligations secured hereunder, Assignee shall execute and deliver to
Assignor all assignments and other instruments as may be reasonably necessary or
proper to terminate Assignee's security interest in the Collateral, subject to
any disposition of the Collateral which may have been made by Assignee pursuant
to this Agreement. For the purpose of this Agreement, the obligations secured
hereunder shall be deemed to continue if Assignor enters into any bankruptcy or
similar proceeding at a time when any amount paid to Assignee could be ordered
to be repaid as a preference or pursuant to a similar theory, and shall continue
until it is finally determined that no such repayment can be ordered.

                                      -6-
<PAGE>

         11. No Waiver. No course of dealing between Assignor and Assignee, nor
any failure to exercise nor any delay in exercising, on the part of Assignee,
any right, power, or privilege under this Agreement or under the Loan Agreement
or any other agreement, shall operate as a waiver. No single or partial exercise
of any right, power, or privilege under this Agreement or under the Loan
Agreement or any other agreement by Assignee shall preclude any other or further
exercise of such right, power, or privilege or the exercise of any other right,
power, or privilege by Assignee.

         12. Rights Are Cumulative. All of Assignee's rights and remedies with
respect to the Collateral whether established by this Agreement, the Loan
Agreement, or any other documents or agreements, or by law shall be cumulative
and may be exercised concurrently or in any order.

         13. Course of Dealing. No course of dealing, nor any failure to
exercise, nor any delay in exercising any right, power or privilege hereunder
shall operate as a waiver thereof.

         14. Attorneys' Fees. If any action relating to this Assignment is
brought by either party hereto against the other party, the prevailing party
shall be entitled to recover reasonable attorneys fees, costs and disbursements.

         15. Amendments. This Assignment may be amended only by a written
instrument signed by both parties hereto. To the extent that any provision of
this Agreement conflicts with any provision of the Loan Agreement, the provision
giving Assignee greater rights or remedies shall govern, it being understood
that the purpose of this Agreement is to add to, and not detract from, the
rights granted to Assignee under the Loan Agreement. This Agreement, the Loan
Agreement, and the documents relating thereto comprise the entire agreement of
the parties with respect to the matters addressed in this Agreement.

         16. Severability. The provisions of this Agreement are severable. If
any provision of this Agreement is held invalid or unenforceable in whole or in
part in any jurisdiction, then such invalidity or unenforceability shall affect
only such provision, or part thereof, in such jurisdiction, and shall not in any
manner affect such provision or part thereof in any other jurisdiction, or any
other provision of this Agreement in any jurisdiction.

         17. Counterparts. This Assignment may be executed in two or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute the same instrument.

         18. California Law and Jurisdiction. This Assignment shall be governed
by the laws of the State of California, without regard for choice of law
provisions. Assignor and Assignee consent to the nonexclusive jurisdiction of
any state or federal court located in Santa Clara County, California.

                                      -7-
<PAGE>

         19. Confidentiality. In handling any confidential information, Assignee
shall exercise the same degree of care that it exercises with respect to its own
proprietary information of the same types to maintain the confidentiality of any
non-public information thereby received or received pursuant to this Assignment
except that the disclosure of this information may be made (i) to the affiliates
of the Assignee, (ii) to prospective transferee or purchasers of an interest in
the obligations secured hereby, provided that they have entered into a
comparable confidentiality agreement in favor of Assignor and have delivered a
copy to Assignor, (iii) as required by law, regulation, rule or order, subpoena
judicial order or similar order and (iv) as may be required in connection with
the examination, audit or similar investigation of Assignee.

         20. WAIVER OF RIGHT TO JURY TRIAL. ASSIGNEE AND ASSIGNOR EACH HEREBY
WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING
OUT OF, OR IN ANY WAY RELATING TO: (I) THIS AGREEMENT; OR (II) ANY OTHER PRESENT
OR FUTURE INSTRUMENT OR AGREEMENT BETWEEN ASSIGNEE AND ASSIGNOR; OR (III) ANY
CONDUCT, ACTS OR OMISSIONS OF ASSIGNEE OR ASSIGNOR OR ANY OF THEIR DIRECTORS,
OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH
ASSIGNEE OR ASSIGNOR; IN EACH OF THE FOREGOING CASES, WHETHER SOUNDING IN
CONTRACT OR TORT OR OTHERWISE.

         IN WITNESS WHEREOF, the parties hereto have executed this Assignment on
the day and year first above written.
