(3) days after delayed party becomes aware of such event, as well as the
cessation thereof.

        12.2 Subcontractor's Default. Any delays in performance by Seller's
subcontractors or suppliers shall be deemed excusable delays with respect to
Seller only if (i) such subcontractor's non-performance is caused by Force

subcontractor from other sources in sufficient time and on customary terms to
prevent interruption of Seller's performance of this Agreement.

        12.3   Termination.

                      (a) If Force Majeure results in a delay to make any
scheduled delivery under this Agreement by more than sixty (60) days, Buyer may
terminate this Agreement in whole or in part and such termination shall not be
deemed a breach of this Agreement.

                      (b) If Buyer does not terminate within such sixty (60) day
period, and the Force Majeure prevails for further forty-five (45) days, Buyer
may terminate this Agreement, but it shall have no right to claim damages from
Seller for breach of the Agreement. The foregoing expresses Buyer's sole remedy
and Seller's sole liability for such termination resulting from Force Majeure.

                                TECHNICAL SUPPORT

infrastructure and process as follows:

LEVEL I TECHNICAL SUPPORT

        Level I Technical Support will be provided by OpenSky to their direct
        and indirect customers. Level I Support is defined as calls* originating
        from OpenSky customers, resellers or distributors regarding Palm
        Products, OpenSky Service, Wireless Service Providers, Minstrel III or
        Minstrel V products including but not limited to pre and post sale
        inquiries concerning the basic operation of the hardware and software,
        functionality, interoperability and capabilities of those products and
        services.

        For calls regarding the Minstrel III and Minstrel V products, OpenSky
        will make every attempt to answer customer questions and resolve issues
        using available tools, documentation, test equipment and other materials
        used to support the Minstrel III and Minstrel V products (see training
        section below). If the customer question/issue regarding the Minstrel
        III or Minstrel V product cannot be resolved by OpenSky support
        personnel to the customers' satisfaction, the issue will be forwarded to
        Novatel Wireless Level II Technical Support for further investigation
        and resolution.

        *Calls include phone calls, e-mail, web-based inquiries, faxes and
        letters.

        staff directly to OpenSky Level I Support personnel to assist in the
        resolution of open customer issues that have not been resolved to the
        satisfaction of OpenSky customers during a Level I Support call. OpenSky
        will have direct access to designated support staff within the Novatel
        Wireless support organization for this purpose. A direct line of
        communication between the two organizations will be established and
        Novatel Wireless support technicians will be available during normal
        OpenSky technical support operation hours to assist in

        resolution of customer problems. Novatel Wireless support engineering
        will work directly with OpenSky support staff to resolve issues and
        answer questions, this may require OpenSky support staff to gather
        additional information and provide system information or test results
        back to Novatel support staff to aid in the definition and resolution of
        the problem. It will be OpenSky support staff's responsibility to
        communicate directly with the end-user customer. Problems that are not
        resolved within three business days or problems that are flagged as
        sensitive/mission critical will be escalated to Level III Technical
        Support for final resolution.

LEVEL III TECHNICAL SUPPORT (ESCALATION)

        Level III Technical Support will be provided by the Novatel Wireless
        support and system engineering staff to resolve issues that cannot be
        satisfactorily resolved by Level I and Level II Support personnel. Level
        III Technical Support will handle all OpenSky product escalations issues
        including unresolved support calls and will work directly with Novatel

                       FIRST AMENDMENT TO SUPPLY AGREEMENT

        This First Amendment to Supply Agreement (this "Amendment") is made as
of October ___, 1999 by and among Novatel Wireless, Inc., a Delaware corporation
("Novatel") and OpenSky Corporation, a Delaware corporation ("OpenSky").

        WHEREAS, Novatel and OpenSky entered into that certain Supply Agreement,
dated and effective as of August 12, 1999 (the "Supply Agreement"); and

        WHEREAS, pursuant to Section 13.10 of the Supply Agreement, Novatel and
OpenSky desire to amend certain terms and provisions of the Supply Agreement;

        NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the parties hereto agree as follows (all capitalized
terms not otherwise defined herein shall have the meanings therefor set forth in
the Supply Agreement):

        1. Pursuant to Section 1.3, OpenSky hereby changes the Mix and delivery
schedule in accordance with Exhibit A hereto.

2.      Section 1.2 is amended in its entirety to read as follows:

                             "1.2 Payments. Buyer shall make payments due to
        Seller for Deliverable Items either directly to Seller or to such bank
        as Seller may designate in writing. Payments for Modems shall be due and
        payable in full, in cash, by Buyer thirty (30) days prior to each
        scheduled delivery of Modems into Seller's Distribution Facility in San
        Diego, California (the "Novatel Distribution Facility") with respect to
        any delivery scheduled in Annex A to be made on or before December 31,
        1999. Payments for Modems shall be due and payable in full, in cash, by
        Buyer within thirty (30) days following the date of each scheduled
        delivery of Modems into the Novatel Distribution Facility with respect
        to any delivery scheduled in Annex A to be made on or after January 1,
        2000. Each delivery of specification compliant Modems in accordance with
        Annex D for which a pre-payment by Buyer has been received may not be
        canceled. Payments for Deliverable Items (other than Modems), shall be
        due and payable in full, in cash, by Buyer within thirty (30) days
        following the date of shipment to end-users on behalf of Buyer. For
        purposes of this Agreement, "Deliverable Items" shall mean any item, or
        parts thereof, that Seller is obligated to provide under this Agreement
        including but not limited to Modems, documentation, know-how and
        information. Payment for shipping and configuration and activation shall
        be due and payable in full, in cash, as set forth in Sections 1.8 and
        2.1, respectively."

        3. Section 1.7 is amended in its entirety to read as follows:

                             "1.7 Delivery and Title. The Modems sold to Buyer
        shall be delivered to the Novatel Distribution Facility in accordance to
        the delivery schedule set forth in Annex A. Title and risk of loss in
        the Modems shall transfer to Buyer FOB Manufacturer, as determined by
        Seller. Seller shall warehouse the inventory on behalf of Buyer and ship
        to end-users the Modems on behalf of Buyer from the Novatel Distribution
        Facility in accordance with Section 1.8 below. Subject to Section 8
        below, all Modems delivered to Buyer shall be non-returnable."

<PAGE>   21
        4. Section 1.8.1 is amended by deleting the date "March 1, 2000" in the
first sentence and replacing it with the date "May 1, 2000", so that the
Shipping Period ends on May 1, 2000.

        5. Section 7.1 is amended by deleting the date "April 1, 2000" in the
first sentence and replacing it with the date "May 1, 2000", so that the term of
the Supply Agreement ends on May 1, 2000.

        6. In all other respects, the Supply Agreement, as herein amended, shall
remain in full force and effect, including Section 1.3 of the Supply Agreement
without giving effect to this Amendment. Subject to the foregoing, to the extent
that any provisions of the Supply Agreement and any provisions of this Amendment
are in conflict, the provisions of this Amendment shall govern. In the event any
one or more of the provisions contained in this Amendment or any instrument
entered into in connection herewith is for any reason held to be invalid or
unenforceable in any respect, that event shall not affect any other provision of
this Amendment or such other instrument.

        7. This Amendment shall be governed by, and construed and enforced in
accordance with, the substantive laws of the State of California, without regard
to its principles of conflicts of laws.

        8. This Amendment shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns, legal
representatives and heirs.

        9. This Amendment may be executed in one or more counterparts, each of
which shall be deemed to be an original, but all of which take together shall
constitute one and the same instrument.
