The foregoing indemnity does not apply to:

                  (a) any Claim based upon any use of a Product other than for
         its intended purpose, whether by Tandy, any customer, end user, or
         otherwise;

                  (b) any Claim which is not timely noticed to Digital
         Convergence by Tandy;

                  (c) any Claim asserting infringement by a combination of a
         Product with other products, which combination is not intended by the
         Parties; and

                  (d) any settlement of a Claim made without Digital
         Convergence's written consent.

         2.7. DESIGNS. MOLDS AND TOOLS. Digital Convergence will notify Tandy
prior to issuing an "Order" (as defined in Section 3.4), and will state on the
Order itself, whether the pricing for the Order should include charges for
designs, molds and tools necessary for the manufacture of the :CAT Products.
Tandy will coordinate payment for, and assist in transferring ownership and
possession of, such designs, molds and tools from the Authorized Manufacturer to
Digital Convergence. As between the parties hereto, Digital Convergence will

license at a royalty rate no less favorable to the rates charged by Digital
Convergence to its top 10 clients.

3.       MANUFACTURING

         3.1.     MANUFACTURING RELATIONSHIP


                                       4
<PAGE>


                  (a) MANAGER. A&A will be the product sourcing manager. The
Tandy employee who shall serve as the primary contact person for Digital
Convergence on all issues related to Product production and delivery will be the
Manager of Internet Alliances (currently, Bill Berryhill). The identified
contact person shall be authorized to act for Tandy, and will interact with A&A
on all product sourcing issues as well as all issues concerning the Authorized
Manufacturer and its manufacturing process, testing and analysis, and quality.
A&A will, as product sourcing manager, oversee all manufacturing operations by
Authorized Manufacturers involving or related to the :CAT Product and, if
applicable, upon the request by Digital Convergence, the pressing of CD-ROM
discs with the Concerto-TM- software.

                  (b) TANDY'S RELATIONSHIP WITH AUTHORIZED MANUFACTURERS. The
parties agree that although Tandy is not the manufacturer of the :CAT Products,
Tandy will stand behind the Authorized Manufacturer[s] by using its best efforts
to monitor and, to the extent possible, control the manufacturing of :CAT
Products to meet scheduled delivery dates and desired Product quality. To that
end, Tandy will cause A&A to have persons from its foreign offices monitor the
Authorized Manufacturer's[s'] adherence to production schedules, perform
sampling inspection at the Authorized Manufacturer's[s'] facility of every lot
of :CAT Products manufactured, and perform routine audits to ensure that factory
personnel are performing ongoing testing similar to that required by Tandy on
its own products.

         3.2. QUALITY. Tandy agrees that it will manage the manufacture of :CAT
Products to meet the same quality goals used to manufacture its own line of
private label products. Digital Convergence may, at its sole cost and expense,
have quality control or other appropriate personnel present at all sites of
manufacture of :CAT Products and may conduct reasonable inspections of the
manufacturing processes of the :CAT Products. Digital Convergence shall
coordinate any such visits and inspections with A&A.

         3.3. COST REDUCTION. The Parties acknowledge that reduction in the cost
of manufacturing the :CAT Product(s) is a primary goal of the Parties. Tandy and
Digital Convergence each agree to use commercially reasonable efforts to reduce
the manufacturing costs for the :CAT Product(s) from present levels. If Tandy
fails to reduce the manufacturing costs within six (6) months of the effective
date of this Agreement, Digital Convergence may, upon payment of all outstanding
invoices (including work in progress) and thirty (30) days prior written notice,
terminate all of Tandy's product sourcing functions under this Agreement and
cause Tandy to terminate all manufacturing by Authorized Manufacturers. This
right of limited termination shall be the sole remedy under this section.

         3.4. ORDERS.

                  (a) PURCHASE ORDERS. Digital Convergence shall submit
manufacturing orders ("Orders") in writing to Tandy. Such Orders shall be
subject to and governed by the terms and conditions of this Agreement. The
preprinted terms and conditions of the Order form shall not apply to, and shall
be of no force and effect with regard to, any Order placed hereunder. Orders
shall, at


                                       5
<PAGE>



a minimum, contain: (i) a description of the Product to be manufactured; (ii)
the quantity desired; (iii) the price; (iv) the delivery date; and (v) the
delivery mechanism pursuant to Section 3.5, below.

                  (b) ORDER ACCEPTANCE. Upon receipt of any Order conforming to
this Agreement, Tandy will forward the Order to an Authorized Manufacturer for
acceptance. Upon receipt of such acceptance, Tandy will provide Digital
Convergence with written notice of acceptance of the Order and acknowledge
tentative delivery date(s) of ordered Products, such written notice of
acceptance to be provided within fourteen (14) business days from Tandy's
receipt of the Order.

                  (c) ORDER REJECTION. If the Order is rejected, Tandy will
provide written notice within fourteen (14) business days from receipt of the
Order specifying that the Order is not acceptable, stating the reasons and
giving Digital Convergence an opportunity to correct it. If the Order is not
correctable, or if the reason for rejection of the Order is Tandy's inability to
fulfill an order, Digital Convergence may exercise its Second Sourcing rights
set out in, and subject to Section 3.12 below.

                  (d) CANCELLATION AND RESCHEDULING. Digital Convergence may,
upon giving written notice fifteen (15) days prior to the date of actual
manufacture of Products, request that any Order be rescheduled or cancelled. In
the event of such cancellation or rescheduling, Tandy shall be entitled to
reimbursement from Digital Convergence in the amount of its reasonable, actual
costs (including costs of the Authorized Manufacturer) plus ten percent (10%) of
such costs. Such additional reimbursement, if any, shall be separately invoiced
by Tandy to Digital Convergence and due and payable within thirty (30) days from
the date of the invoice.

                  (e) PRODUCT SPECIFICATIONS AND DESIGN. From time to time,
Digital Convergence will provide Tandy with specifications for one or more of
the Products ("Product Specifications") which Tandy will provide to the
Authorized Manufacturer. Based upon Product Specifications, Tandy will have the
Authorized Manufacturer create a design for the Product ("Product Design") which
Tandy will provide to Digital Convergence. Digital Convergence shall either
approve or reject the Product Design in writing, and shall state the reasons for
any rejection. If the Product Design is approved, subject to Section 3.10,
Digital Convergence may begin submitting Orders for the Product. If the Product
Design is rejected, Tandy will have the Authorized Manufacturer modify the
Product Design to eliminate the basis of the rejection, and will re-submit the
Product Design for approval or rejection.

                  (f) REQUESTED CHANGES TO PRODUCTS. After a Product Design has
been approved, either Party may submit a written request for changes in the
Product, which the other may approve in its discretion. If the change appears to
be substantial, either party may notify the other party that formal change
control procedures will be utilized as follows: Within thirty (30) days of
receipt of a written request for a substantial change in the Product, Tandy will
discuss the change with the Authorized Manufacturer and will inform Digital
Convergence of the price effect, if any, as well as the point of incorporation
and anticipated logistic considerations of such change. Both Parties agree to
negotiate in good faith regarding the incorporation of any such change, and if
incorporated, the


                                       6
<PAGE>



price and other terms concerning such change. However, neither Party is under
any obligation to agree to change requests unless otherwise expressly stated in
this Agreement.

         3.5. DELIVERY, INSPECTION AND ACCEPTANCE. The Parties anticipate two
basic delivery mechanisms under this Agreement. Tandy may deliver Products to
Digital Convergence or its designate for distribution by Digital Convergence or
its designate as set forth in subsection (a) below, or Tandy may deliver
Products to Digital Convergence by delivering same to Tandy's distribution
centers for distribution by Tandy to RadioShack stores, as set forth in
subsection (b) below.

                  (a)      DELIVERY TO DIGITAL CONVERGENCE.

                           (i) DELIVERY. Delivery of Products to Digital
         Convergence shall be deemed completed when delivered duty paid to
         Digital Convergence's carrier or forwarding agent which is intended to
         deliver the Products from the U.S. port of entry to their ultimate
         "ship to" location (hereinafter each is referred to as a "Delivery").
         Unless specified in Digital Convergence's Orders, at least thirty (30)
         days prior to the scheduled delivery date, Digital Convergence shall
         give Tandy written instructions regarding the ultimate "ship to"
         location, forwarding agent and/or carrier and type of conveyance by
         which such purchases are to be shipped from the U.S. port of entry to
         the ultimate "ship to" location. Should Digital Convergence fail to
         arrange and pay for the forwarding agent and/or carrier, Tandy shall
         select same, which selection shall conform to the standard commercial
         practices of Tandy for shipment of its products. All costs of
         transportation of Products from the U.S. port of entry to the ultimate
         "ship to" location shall be the responsibility of Digital Convergence.

                           (ii) TITLE AND RISK OF LOSS. Title and risk of loss
         and damages shall pass from Tandy to Digital Convergence upon
         completion of Delivery as set forth in Section 3.5(a)(i) above.

                           (iii) SECURITY INTEREST. Until the purchase price and
         all other charges payable by Digital Convergence hereunder are received
         in full, Tandy will retain a security interest in the Products, and
         proceeds therefrom, under the Uniform Commercial Code. If requested by
         Tandy, Digital Convergence agrees to execute such documents as may be

million units of :CAT Products, or should a need for a Second Source arise
pursuant to Section 12.6 ("Delays"), Section 3.11 ("Large Scale Failures"), or
Tandy's rejection of an Order due to the inability of an Authorized Manufacturer
to fill the Order pursuant to Section 3.4(c) ("Order Rejection"), Tandy agrees
that Digital Convergence may purchase :CAT Products from manufacturers other
than those Authorized Manufacturers utilized by Tandy to perform its services
under this Agreement (collectively "Second Sources"), provided that: (i) Digital
Convergence has paid all invoices properly and currently due (including costs
and work in progress); and (ii) Digital Convergence provides sixty (60) days
prior written notice to Tandy that Digital Convergence intends to purchase :CAT

or at such other address as may be substituted by notice given as herein
provided. The giving of any notice required hereunder may be waived in writing
by the party entitled to receive such notice. Every notice, demand, request,
consent, approval, declaration, delivery or other communication hereunder shall
be deemed to have been duly given or served on the date on which personally
delivered, with receipt acknowledged, or three (3) business days after the same
shall have been deposited in the United States mail.

personal to Tandy and may not be assigned without the written consent of Digital
Convergence.

         12.3. HEADINGS. The section or other headings herein are inserted only
for convenience and ease of reference and are not to be considered in the
construction or interpretation of any provision of this Agreement. Unless
otherwise stated, references to Sections herein are references to Sections
hereof.

         12.4. GOVERNING LAW; VENUE; LIMITATIONS. This Agreement and the rights
and obligations of the Parties hereunder shall be governed by and construed in
accordance with the laws of the State of Texas without reference to its
provisions on conflict of laws. Texas is the exclusive venue if the action
includes a claim arising out of or relating to this Agreement or the use of the
Product. All payments to Tandy hereunder shall be made in Fort Worth, Tarrant
County, Texas and all disputes hereunder shall be resolved in the applicable
state or federal courts located in Tarrant County, Texas. Any and all claims
hereunder shall be raised within one (1) year of the event or occurrence from
which they arise.

         12.5. COSTS. If either Party must bring suit to enforce or preserve its
rights under this Agreement, the Party prevailing in such suit shall be entitled
to all costs and expenses related to such enforcement, including, but not
limited to, reasonable attorneys' fees.

         12.6. DELAYS. Neither Party shall be liable to the other Party for any
delay or failure to perform under this Agreement due to causes beyond the
reasonable control of the nonperforming Party. Should such delay occur, the date
or dates for performance shall be extended for a period equal to the number of
days during which performance is so delayed. Notwithstanding the foregoing, if
the Delivery of any :CAT Product is delayed for more than sixty (60) days due to
any cause beyond the control of Digital Convergence but within the control of
Tandy or the Authorized Manufacturer, Digital Convergence may cancel its Order
for the delayed :CAT Product by giving written notice to Tandy of such
cancellation at any time prior to Delivery thereof, and may exercise its Second
Sourcing rights set out in, and subject to, Section 3.12 in lieu of any and all
other remedies. Such cancellation will be without penalty if the cause of the
delay was within Tandy's or the Authorized Manufacturers' control. Otherwise,
the Parties will cooperate in good faith to reasonably apportion the costs of
cancellation among Tandy, Digital Convergence and the Authorized Manufacturer.

         12.7. SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law. If the application of any provision of this Agreement to any
particular facts or circumstances shall be held to be invalid or unenforceable
by a court of competent jurisdiction, then: (i) the validity and enforceability
of such provision as applied to any other particular facts or circumstances and
the validity of other provisions of this Agreement shall not in any way be
affected or impaired thereby; and (ii) such provision shall be enforced to the
maximum extent possible so as to effect the intent of the Parties and shall be
reformed without further action by the Parties to the extent necessary to make
such provision valid and enforceable while preserving the original intent of the
Parties.

         12.8. WAIVER. The waiver by either Party of a breach of or a default
under any provision of this Agreement shall be in writing and shall not be
construed as a waiver of any subsequent breach of or default under the same
or any other provision of this Agreement, nor shall any delay or omission on
the part of either Party to exercise or avail itself of any right or remedy
that it has or may have hereunder or by law or at equity operate as a waiver
of any right or remedy.

         12.9. ENTIRE AGREEMENT. This Agreement together with the Exhibits
hereto constitutes the entire agreement between the Parties pertaining to the
subject matter hereof and supersedes all previous communications, agreements,
and understandings between the Parties relating to the subject matter hereof.
Neither Party has entered into this Agreement in reliance upon any
representation, warranty, or undertaking of the other Party that is not set out
or referred to in this Agreement. No amendment or modification of any provision
of this Agreement shall be effective unless in writing and signed by a duly
authorized representative of each Party.

         12.10. APPROVALS AND CONSENTS. Except as expressly provided otherwise

Party is required by any provision of this Agreement, that action will not be
unreasonably delayed or withheld.

enter into additional agreements or assignments, or will obtain other

         12.12. REPRESENTATION OF COUNSEL; MUTUAL NEGOTIATION. Each Party
acknowledges it has had the opportunity to be represented by counsel of its
choice in negotiating this Agreement. This Agreement will therefore be deemed to
have been negotiated and prepared at the joint request, direction, and
construction of the Parties, at arms length, with the advice and participation
of counsel, and will be interpreted in accordance with its terms without favor
to any Party.

         12.13. SUPREMACY OF CONTRACT. If there is any conflict between the
terms and conditions of this Agreement and any Exhibit, Schedule, addendum, or
document incorporated by reference in this Agreement, the body of this Agreement
will control.

         12.14. MEDIA RELEASES. The Parties shall cooperate with each other to
prepare a mutually acceptable press release with regard to the announcement of
this Agreement.

         12.15. NO PARTNERSHIP. The sole relationship between the Parties shall
be that of independent contractors. Nothing herein shall be construed to
constitute the Parties as partners, joint venturers, or agents of each other in
any way whatsoever. Neither Party shall make any warranties or representations,
or assume or create any obligations, on the other Party's behalf. Each Party
shall be solely responsible for the actions of its respective employees, agents,
and representatives.

agreement related to the manufacturing and marketing of such a product.

faith to determine if it is feasible to market a "premium" :CAT Product. If the

on and shall inure to the benefit of the parties hereto, their successors,
administrators, heirs and assigns.

         12.19. SALES, USE, PROPERTY TAXES. All liability for sales/use taxes or
property taxes due or claimed due as a result of the distribution of the
Products to end-users (if any) shall be the responsibility of Digital
Convergence.

         IN WITNESS WHEREOF, the Parties have caused this Agreement to be duly
executed.
