together with the goodwill associated therewith (collectively, the

     B.  Pursuant to the terms of the Asset Purchase Agreement between Licensor
and Licensee dated as of the date hereof (the "Asset Agreement"), Licensor has
transferred and assigned to Licensee certain assets relating to electronic

     C.  Licensee desires to secure from Licensor, and Licensor desires to
grant to Licensee, a license to use the Technology, Patents, Patent Rights and
Trademarks (the "Rights") subject to the terms and conditions set forth herein.

     NOW, THEREFORE, in consideration of the premises, the mutual covenants
contained herein, and other good and valuable consideration, the parties agree

part by, or is manufactured using a process that is covered in whole or in part
by, a Patent or Patent Right or (ii) a product that unless made, used or sold
pursuant to this Agreement, would infringe a Patent or Patent Right.

2.       License. Subject to the remaining provisions of this Agreement,
Licensor hereby grants to Licensee an exclusive and non-transferable license
(the "License") to use and practice the Rights in connection with the design,
manufacture, production, advertisement, promotion, sale and distribution of the
Products throughout the world. Nothing in this Section 2 or otherwise in this
Agreement shall be construed as conferring any right to use in any manner any
name, trademark, service mark, logo or trade name of Licensor other than the
Trademarks. Licensee shall have no right to sublicense any of its rights or
obligations under the License to any third party without the prior written
consent of Licensor.

3.       Obligations of Licensee.

         3.1      Compliance With Laws. During the term of this Agreement,
Licensee shall use the Rights, shall manufacture, advertise, sell and
distribute the Products, and shall otherwise conduct its business in compliance
with all applicable laws, statutes, rules and regulations.

         3.2      Intellectual Property.

                  3.2.1    Execution of Documents. Licensee shall make all
necessary disclosures, execute, acknowledge and deliver all instruments and
perform all acts requested by Licensor to secure and maintain in the name of
Licensor, or its designee, patent and other intellectual property protection
for the Rights. In the event Licensor is unable, for any reason whatsoever, to
obtain the signature of Licensee to any document or instrument necessary or
desirable to obtain ownership of, apply for protection of, or enforce any
action with respect to, any patent, copyright, trade secret or other
intellectual property right, Licensee hereby irrevocably designates and
appoints Licensor, and its duly authorized officers and agents, as Licensee's
agent and attorney-in-fact, whose power is expressly coupled with an interest,
to act for and on behalf of Licensee, to execute such documents and to take all
of the lawfully permitted actions to protect Licensor's interest in any patent,
copyright, trade secret or other intellectual property right with the same
legal force and effect as if executed by Licensee.

                  3.2.2    Marking of Products. Licensee shall mark all
Products with such patent and/or trademark legends as Licensor may from time
to time prescribe in writing in such manner and form as Licensor may require

<PAGE>   12
                  3.2.3    Use of the Trademarks. Licensee acknowledges that
the maintenance of the high quality of the Products is a material condition of
this Agreement. Accordingly, Licensor shall have the right to receive, at no
cost to Licensor, and test for approval purposes samples of all Products
incorporating the Trademarks, prior the sale, use or distribution of any such
Products. In addition, all advertising, promotional materials, packaging and
other materials containing or displaying any of the Trademarks shall be
forwarded to Licensor for its written approval prior to any use thereof by
Licensee. Licensee shall not sell, use or distribute any Product or material
disapproved by Licensor. Licensor acknowledges and agrees that Licensor is the
sole and exclusive owner of the Trademarks, and Licensee shall obtain no right
or interest in the Trademarks by virtue of its use thereof (all use of the
Trademarks by Licensee inuring to benefit of Licensor). Licensor shall not take
any action which is inconsistent with Licensor's exclusive ownership of and use
of the Trademarks, except as expressly provided herein.

         3.3      Confidentiality. During the term of this Agreement and
thereafter, Licensee (a) shall not directly or indirectly use, communicate or
divulge or enable another to use, communicate or divulge any Confidential
Information, and (b) shall not divulge to Licensor confidential information of
any other party the use, communication or disclosure of which is protected by
comparable confidentiality commitments, except as expressly permitted by this
Agreement.

         3.4      Best Efforts. Licensee shall at all times at its own cost and
expense use its best efforts and all due diligence energetically and
aggressively to develop the market for the Products throughout the world, to
promote the sale, distribution and use of the Products therein, and to enhance
the reputation and goodwill associated with the Products and the Trademarks.
See Rider 3.4 which is incorporated herein.

         3.5      Reasonable Restrictions. Licensee acknowledges and agrees
that (a) the provisions of Sections 3.2 and 3.3 hereof are reasonable and
necessary to protect the legitimate interests of Licensor, (b) the restrictions
contained in Sections 3.2 and 3.3 will not prevent Licensee from earning or
seeking a livelihood, (c) the restrictions contained in Sections 3.2 and 3.3
shall apply in all areas where such application is permitted by law, and (d)
any violation of this Agreement by Licensee would result in irreparable harm to
Licensor. Accordingly, Licensee consents and agrees that, if it violates any of
the provisions of this Agreement, Licensor shall be entitled to, in addition to
other remedies available to it, an injunction to be issued by any court of
competent jurisdiction restraining Licensee from committing or continuing any
violation of this Agreement, without being required to post a bond or other
security, or any other undertaking. In the event that the whole or any part of
any provision of Sections 3.2 or 3.3 hereof shall be determined to be invalid
by reason of the extent, duration, scope or other provision set forth therein,
the extent, duration, scope or other provision of that section shall be reduced
so as to cure such invalidity and in its reduced from the provisions of
Sections 3.2 and 3.3 shall be enforceable in the manner contemplated hereby.

         3.6 Inspection. Upon reasonable advance notice to Licensee, Licensee
shall permit Licensor and Licensor's employees or representatives to enter and
examine Licensee's facility and places of business and to inspect the Products,
its inventories of the Products, service records and other relevant documents
related to the Products and any components thereof.

4.       License Consideration.

         4.1      License Royalty Fee. Licensee shall pay to Licensor a royalty
fee equal to two percent (2%) of all gross sales of the Products (other than
Products sold more than 3 years after the date hereof which are covered solely
by a patent application; provided that such royalty fee shall not be less than
the guaranteed minimum royalty fee for each calendar quarter, as set forth
below; provided further that if the cumulative amount of royalty fees paid by
Licensee exceeds the guaranteed minimum cumulative royalty fee for such
calendar quarter, as set forth below, Licensee shall not be required to pay the
guaranteed minimum royalty fee for such calendar quarter. In no event shall the
foregoing proviso be deemed to release Licensee from its obligations to pay
Licensor the royalty fees as described above. If Licensee fails to pay the
guaranteed minimum royalty fee for any calendar quarter for a period of more
than 10 days following receipt of notice by Licensee of such failure, then in
addition to the right to demand and collect the guaranteed minimum royalty,
Licensor may declare the License to be non-exclusive. Upon such declaration,
Licensor shall be entitled, without liability or charge, to use, copy, promote,
distribute, sell, encumber, create derivative works of, revise and modify,
license, develop, manufacture, advertise, sale, distribute, or exploit, in any
manner, any or all of the Rights.

         4.2      Payment of Royalty Fees. The royalty fees due hereunder shall
be paid by Licensee to Licensor within twenty (20) days after the close of each
calendar quarter. Time is of the essence with respect to all provisions of this
Agreement relating to the payment of money. A failure by Licensee to make any
payment required hereunder in a timely fashion shall constitute a material
breach of this Agreement. All payments to Licensor hereunder shall be in U.S.
dollars by bank transfer to such bank account as Licensor may from time to time
designate in writing and shall be accompanied by a remittance advice
identifying the specific payments made. In the event of any underpayment or
late payment of any royalty fee payable hereunder, Licensee shall immediately
remit to Licensor the full amount owed, together with a late payment charge
calculated at a rate of one and one-half percent (1 1/2%) per month, compounded
on a monthly basis, or maximum rate permitted by law, whichever is less. In
addition, if the amount of such underpayment is in excess of two percent (2%)
of the amount properly payable by Licensee, Licensee shall promptly reimburse
Licensor for the cost of any examination or audit.

         4.3      Accounting and Reporting.


                                      -4-
<PAGE>   14
                  4.3.1    Records and Inspection. Licensee shall keep accurate
books of account, records and invoices concerning its business consistent with
generally accepted accounting principles. Said books, records and invoices
shall be maintained for a period of at least three (3) years after termination
or expiration of this Agreement and shall be available for inspection and
copying by Licensor or its duly appointed representative during regular
business hours and upon reasonable notice. Licensee shall cooperate fully with
Licensor in conducting such inspection.

                  4.3.2    Reporting. On or before the date specified in
Section 4.2 above for each quarterly payment of the royalty, Licensee shall
submit to Licensor a statement setting forth all sales of the Products (by
product category, style, units, dollars, and customer names and telephone
numbers), Licensee's aggregate gross revenues during such calendar quarter, the
total amount of the royalty fee payable to Licensor and the difference between
the quarterly royalty and the monthly royalty fee payable to Licensor pursuant
to Section 4.1, or a statement that no sales of the Products were made during
such month. Each quarterly statement shall be accompanied by a written
certification from the chief financial officer of Licensee that the statement
is correct and complete and prepared in compliance with this Agreement. Within
ninety (90) days after the end of each calendar year of this Agreement,
Licensee shall submit to Licensor, at Licensee's sole expense, an audited
financial statement for the preceding calendar year (by independent public
accountants acceptable to Licensor), and setting forth the aggregate royalty
fee for the preceding calendar year and the basis of calculation. Licensee
shall submit to Licensor within ninety (90) days after termination or
expiration of this Agreement a written statement certified by Licensee's chief
financial officer identifying all revenues upon which the royalty fee is
payable hereunder but which were not previously reported.

5.       Term and Termination.

         5.1      Term and Termination. Subject to the remaining provisions of
this Section 5, the term of this Agreement shall commence as of the date hereof
and shall terminate upon the expiration of the last of the Patents to expire
(as the life of such Patent may be extended or prolonged by any extensions,
renewals, continuations, continuations in part, or divisions thereof). This
Agreement may be terminated by Licensor immediately upon notice to Licensee
upon the occurrence of an "Event of Default" as defined in Section 10.1 of the
Asset Agreement or in the event that Licensee does any of the following: (a)
files a petition in bankruptcy or is adjudicated bankrupt or insolvent, or
makes an assignment for the benefit of creditors, or an arrangement pursuant to
any bankruptcy law, or if a receiver is appointed for Licensee or for
Licensee's business and such receiver is not discharged within thirty (30)
days, provided that the bankruptcy laws permit such Action by Licensor, (b)
fails to continue its business in the manner now conducted, (c) is late more

more than twice during any one (1) calendar year, (d) attempts to sublicense or
assign any of its rights or obligations under this Agreement without Licensor's
prior written approval, (e) fails to make any guaranteed minimum royalty
payment for a period of 180 or more days, (f) fails to obtain or maintain
insurance in the amount and of the type provided for herein, (g) engages in any
conduct or practice which in Licensor's judgment is detrimental to the good
name, goodwill or reputation of Licensor, any Affiliate of Licensor or the
Trademarks, or (h) directly or indirectly,


                                      -5-
<PAGE>   15
contests, opposes, or challenges any of the Rights, attempts to obtain
ownership of the Rights in any country, or assists any third party with
respect to the foregoing.

     5.2  Consequences of Termination or Expiration. Upon termination or
expiration of this Agreement for any reason, (a) the License granted hereunder
shall immediately terminate, (b) Licensee shall immediately and forever cease
from using the Rights, (c) Licensee shall immediately pay to Licensor all
amounts due to Licensor pursuant to Section 4 hereof for all Products sold
prior to the date of termination or expiration of this Agreement and any
guaranteed minimum royalty payments then due, (d) Licensor shall be entitled,
without liability or charge, to use, copy, promote, distribute, sell, encumber,
create derivative works of, revise and modify, license, develop, manufacture,
advertise, sale, distribute, or exploit, in any manner, any or all of the
Rights, and (e) Licenesee shall promptly return to Licensor all documents in
its possession or under its control relating to the Rights or to the rights
assigned in Subsection 3.2.2, together with any and all copies thereof. The
provisions of this Section 5.2, as well the provisions of Sections 3.2, 3.3,
3.4, 3.5, 4, 6 and 8, shall survive the expiration or termination of this
Agreement, irrespective of the reason therefor.

6.   Warranties: Disclaimers. Licensee acknowledges and agrees that the Rights
are being licensed to Licensee "AS IS," with absolutely no warranties of any
kind. Licensee further acknowledges that John Ossenmacher ("Ossenmacher"), an
officer of Licensee, was formerly president of Solium and, therefore, is
intimately familiar with the Rights. Moreover, with the assistance of
Ossenmacher, Licensee has evaluated for itself the Rights, their actual and
potential applications and their actual and potential commercial value and
viability. Licensor shall have no obligation to obtain or maintain Patent
protection for the Rights in any nation, provided that if LICENSOR elects not
to obtain or maintain any issued patent(s) or patent application(s) Licensee
may authorized and reimburse Licensor for the costs and attorney fees for
maintaining such patent(s) or patent application(s). Licensee is aware that
Licensor intends to abandon a significant number of its pending patent
applications unless Licensee elects to pay for the prosecution of such
applications. Without limiting the generality of the foregoing, LICENSOR (A)
SPECIFICALLY DISCLAIMS ALL WARRANTIES OF ANY KIND REGARDING THE RIGHTS,
INCLUDING ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE, (B) MAKES NO REPRESENTATIONS OR WARRANTIES REGARDING THE SUITABILITY
OF THE RIGHTS FOR LICENSEE'S OR ANY THIRD PARTY'S ACTUAL OR INTENDED USES, AND
(C) NO REPRESENTATIONS OR WARRANTIES AS TO WHETHER THE RIGHTS INFRINGE ON THE
PATENT, TRADEMARK OR OTHER PROPRIETARY RIGHT OF ANY THIRD PARTY. IN NO EVENT
SHALL THE LICENSOR (OR ANY AFFILIATE OF LICENSOR) BE LIABLE TO LICENSEE OR ANY
THIRD PARTY FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES
RESULTING FROM THE USE, OR INABILITY TO USE, THE RIGHTS, OR OTHERWISE ARISING
OUT OF THIS AGREEMENT.

7.   Infringement. In the event that Licensee or Licensor learns of any
infringement by any third party of any of the Rights, it shall promptly notify
the other party in writing. At any time after any such notice, Licensor shall
have the exclusive right but not the obligation, at Licensor's expense, to
commence legal action against such infringer and may settle or compromise any
such



                                      -6-
<PAGE>   16
 


action. Licensor shall be entitled to all payments recovered in connection with
such action, to the exclusion of Licensee. Licensee may not commence any such
action without the prior written consent of Licensor. In the event any third
party commences a legal action, suit or proceeding against Licensee alleging
that its use of the Rights infringe or violate any right of such third party,
Licensee shall promptly notify Licensor in writing. At any time after any such
notice, Licensor shall have the first right but not the obligation, at
Licensor's cost and expense, assume the defense of such action and, in
connection therewith, settle or compromise any such action. If Licensor does
not assume the defense of such action within thirty (30) days of such notice,
Licensee may, at Licensee's sole cost and expense, defend itself in such
action; provided that Licensee shall not settle any action without the prior
written consent of Licensor. Licensee and Licensor shall assist and cooperate
fully with each other in connection with any legal action.

8.   Indemnification and Insurance. Licensor shall have no liability to Licensee
or any third party with respect to the use of the Rights or in connection with
the design, manufacture, production, advertisement, promotion, sale and
distribution of the Products throughout the world pursuant to this Agreement.
Licensee shall indemnify, defend, and hold harmless Licensor and Licensor's
Affiliates from and against any and all claims, suits, losses, damages, fees and
expenses, including without limitation attorneys' fees and costs, arising out of
or relating to the design, manufacture, production, advertisement, promotion,
sale and distribution of the Products, all components thereof and Licensee's use
of the Rights, in any country or subdivision thereof, including, without
limitation any claims by third parties that the Rights infringe on the rights of
any third parties. During the term of this Agreement, Licensee shall obtain and
maintain employer's liability, workers' compensation, comprehensive general
liability, and product and completed operations insurance, with limits of
liability and issued by insurers approved in writing by Licensor, and shall
furnish Licensor with a certificate of insurance naming Licensor as an
additional insured, providing for such insurance and requiring sixty (60) days'
prior written notice to Licensor of any cancellation or modification of such
insurance. In no event shall Licensee sell, distribute or advertise the Products
prior to obtaining the insurance provided above.

9.   Miscellaneous.

     9.1  Assignability. Licensee shall not, without the prior written consent
of Licensor, assign, transfer, sell or encumber, by operation of law or
otherwise, this Agreement or any of its rights or obligations hereunder. Subject
to the foregoing, this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns. Nothing
expressed or implied in this Agreement is intended or shall be construed to
confer upon or give to any person, other than the parties to this Agreement, any
right, remedy or claim under or by reason of this Agreement or of any term,
covenant or condition of this Agreement, including, without limitation, any
claims by third parties that the Rights infringe on the rights of any Third
Parties.

     9.2  Notices. All notices, requests or consents required or permitted
under this Agreement shall be made in writing and shall be given to the other
party by personal delivery, overnight air courier (with receipt signature) or
facsimile transmission (with "answerback" confirmation of transmission), sent
to such party's address or facsimile number as are set forth 


                                      -7-
<PAGE>   17

below such party's signature to this Agreement, or such other address or
facsimile number of which such party has given notice pursuant to this
Subsection 9.2. Each such notice, request or consent shall be deemed effective
upon the date of actual receipt, receipt signature or confirmation of
transmission, as applicable, except as may otherwise be expressly provided for
herein.

     9.3  Amendments; Waivers; Severability. This Agreement may be amended,
modified, superseded, canceled, renewed or extended and the terms or covenants
of this Agreement may be waived only by a written instrument executed by the
parties to this Agreement or, in the case of a waiver, by the party waiving
compliance. The failure of any party at any time or times to require
performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party of the breach
of any term or provision contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed
as, a further or continuing waiver of any such breach, or a waiver of the
breach of any other term or covenant contained in this Agreement. Any
provision of this Agreement that is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     9.4  Relationship of Parties. Licensor and Licensee are and intend to
remain independent parties. Nothing contained in this Agreement shall be deemed
or construed to create the relationship of principal and agent or of
partnership or joint venture, and neither party shall hold itself out as an
agent, legal representative, partner, subsidiary, joint venturer, servant or
employee of the other. Neither party nor any officer or employee thereof shall,
in any event, have any right collectively or individually, to bind the other
party, to make any representations or warranties, to accept service of process,
to receive notice or to perform any act or thing on behalf of the other party,
except as authorized in writing by such other party in its sole discretion.

     9.5  Controversies; Venue. This Agreement shall be governed by and
construed and enforced in accordance with the internal substantive laws of the
