                         COMMON STOCK PURCHASE AGREEMENT

        This COMMON STOCK PURCHASE AGREEMENT (this "Agreement") is entered into
as of August 31, 2000, by and between OmniSky Corporation, a Delaware
corporation (the "Company"), and America Online, Inc., a Delaware corporation
(the "Purchaser").

                                    RECITALS

        WHEREAS, the Purchaser desires to purchase shares of the Company's
common stock ("Common Stock") in a private placement to close concurrently with,
but not before, the closing of the initial public offering of the Company's
common stock (the "IPO") pursuant to a Registration Statement on Form S-1 filed
with the Securities and Exchange Commission (the "Commission") (such
registration statement, as amended, shall be referred to herein as the
"Registration Statement"); and

        WHEREAS, the Company desires to issue and sell the Shares (as defined
below) to the Purchaser on the terms and conditions set forth herein.

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual promises hereinafter set forth, the parties hereto agree as follows:

1.      AGREEMENT TO SELL AND PURCHASE

        1.1. AUTHORIZATION OF SHARES. On or prior to the Closing (as defined in
Section 2 below), the Company shall have authorized the sale and issuance to the
Purchaser of the Shares. Prior to the Closing, the Company will have adopted and
filed a Certificate of Incorporation (the "Certificate of Incorporation") with
the Secretary of State of the State of Delaware authorizing sufficient shares of
Common Stock to cover the sale and issuance of the Shares to be purchased
hereunder.

        1.2. SALE AND PURCHASE OF COMMON STOCK. Subject to the terms and
conditions hereof, the Company hereby agrees to issue and sell to the Purchaser
and the Purchaser agrees to purchase from the Company, at the Closing, that
whole number of shares of Common Stock equal to the quotient determined by
dividing $5 million by the per share Price to Public (as defined below) and
rounding down to the nearest whole number. The shares of Common Stock to be
purchased hereunder are referred to as the "Shares". The per share purchase
price for the Shares purchased hereunder shall be the per share Price to Public.
The "Purchase Price" shall be equal to the amount obtained by multiplying the
Shares by the per share Price to Public.

        For purposes of this Agreement, the term "Price to Public" shall mean
the Price to Public set forth on the cover page of the final Prospectus (as
defined below), less the underwriting discounts and commissions per share as set
forth on the cover page of the final Prospectus. For purposes of this Agreement,
the term "Prospectus" means the prospectus, as amended, on file with the
Commission at the time the Registration Statement becomes effective, including
the information deemed to be part of the Registration at the time of
effectiveness pursuant to Rule
<PAGE>   3
430A, if applicable, except that if the Prospectus filed by the Company pursuant
to Rule 424(b) differs from the prospectus on file at the time the Registration
Statement becomes effective, the term "Prospectus" shall refer to the Rule
424(b) Prospectus from and after the time it was filed with the Commission or
transmitted to the Commission for filing.

        1.3. HART-SCOTT-RODINO COMPLIANCE. Notwithstanding anything else in this
Agreement, if the sale and issuance of the Shares is subject to the premerger
notification requirements of the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), it shall be a condition to the Closing that
any waiting period under the HSR Act applicable to the purchase of the Shares
shall have expired or been terminated and any approvals required thereunder
shall have been obtained, and the parties shall cooperate in promptly filing
premerger reports and in taking all steps reasonably necessary to obtain early
termination of any applicable HSR Act waiting periods. If any such waiting
period shall not have expired or been subject to early termination on or before
the date ninety (90) days from the date of this Agreement, either party may
terminate this Agreement by giving written notice to the other.

2.      CLOSING, DELIVERY AND PAYMENT

        Subject to the terms of Section 5, the closing of the sale and purchase
of the Shares under this Agreement (the "Closing") shall take place concurrently
with, but not before, the closing of the IPO at the offices of Wilson Sonsini
Goodrich & Rosati, Professional Corporation, 650 Page Mill Road, Palo Alto,
California 94304. The date of the Closing is referred to as the "Closing Date."
At the Closing, subject to the terms and conditions hereof, the Company will
deliver to the Purchaser a certificate representing the number of Shares to be
purchased at the Closing against payment in immediately available funds by or on
behalf of the Purchaser of the Purchase Price in cash, by wire transfer or by
such other means as shall be mutually agreeable to the Purchaser and the
Company.

3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and
warrants to the Purchaser that the representations and warranties set forth in
the underwriting agreement entered into with the managing underwriters of the
IPO (the "Underwriting Agreement") will be true and correct in all respects and
are hereby incorporated by reference herein. Except as set forth in the Schedule

that have not been properly waived or complied with. When issued in compliance
with the provisions of this Agreement and the Certificate of Incorporation, the
Shares will be validly issued, fully paid and nonassessable, and will be free of
any liens or encumbrances; provided, however, that the Shares may be subject to

material modification of, any material contract or otherwise give any other

or be in conflict with or constitute a default under any term, of its
Certificate of Incorporation or bylaws or any law, statute, order or regulation
applicable to the Company.

        3.4. LITIGATION. There is no action, suit, proceeding nor, to the
Company's knowledge, any investigation pending or currently threatened against
the Company, that questions the validity of this Agreement or the right of the
Company to enter into such agreement, or which might result, either individually
or in the aggregate, in any material adverse change in the assets, affairs or
condition (financial or otherwise) of the Company.

        3.5. GOVERNMENTAL CONSENT. No consent, approval or authorization of, or
designation, declaration or filing with, any governmental authority on the part
of the Company is required in connection with the valid execution, delivery, and
performance of this Agreement or the offer, sale or issuance of the Shares, or
the consummation of any other transaction contemplated by this Agreement, except

(the "Securities Act") and state securities laws and regulations, which filings
will be made timely in accordance with the applicable law or regulation, or the
HSR Act, if applicable.

        3.6. INTELLECTUAL PROPERTY RIGHTS. To the knowledge of the Company, the

4. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser hereby
represents and warrants to the Company as follows:

        4.1. REQUISITE CORPORATE POWER AND AUTHORITY. The Purchaser has all
necessary corporate power and authority under all applicable provisions of law
to execute and deliver this Agreement and to carry out the provisions of this
Agreement. All action on the Purchaser's part required for the lawful execution
and delivery of this Agreement has been or will be effectively taken prior to
the Closing. This Agreement, when executed and delivered, will be a valid and
binding obligation of the Purchaser, enforceable against the Purchaser in
accordance with its terms, except (i) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
affecting enforcement of creditors' rights and (ii) general principles of equity
that restrict the availability of equitable remedies.

        4.2. CONSENTS. All consents, approvals, orders, authorizations,
registrations, qualifications, designations, declarations or filings with any
governmental or banking authority on the part of the Purchaser required in
connection with the consummation of the transactions contemplated in this
Agreement have been or shall have been obtained prior to and be effective as of
the Closing.

        4.3. INVESTMENT REPRESENTATIONS. The Purchaser understands that the
Shares have not been registered under the Securities Act. The Purchaser also
understands that the Shares are being offered and sold pursuant to an exemption
from registration contained in the Securities Act based in part upon the
Purchaser's representations contained in the Agreement. The Purchaser hereby
represents and warrants as follows:

             (a) The Purchaser is an Accredited Investor. The Purchaser
        represents that the Purchaser is an "accredited investor" within the
        meaning of Rule 501(a) of Regulation D under the Securities Act.

             (b) The Purchaser Bears Economic Risk. The Purchaser must bear
        the economic risk of this investment indefinitely unless the Shares are
        registered pursuant to the Securities Act, or an exemption from
        registration is available. The Purchaser understands that there is no
        assurance that any exemption from registration under the Securities Act
        will be available and that, even if available, such exemption may not
        allow

                                        4
<PAGE>   6

        the Purchaser to transfer all or any portion of the Shares under the
        circumstances, in the amounts or at the times the Purchaser might
        propose.

             (c) Acquisition For Own Account. The Purchaser is acquiring the
        Shares for the Purchaser's own account for investment only, and not with
        a view towards their distribution within the meaning of the Securities
        Act.

             (d) The Purchaser Can Protect Its Interest. The Purchaser
        represents that by reason of its, or its management's, business or
        financial experience, the Purchaser has the capacity to protect its own
        interests in connection with the transactions contemplated in this
        Agreement. The Purchaser is not a corporation, trust or partnership
        specifically formed for the purpose of consummating these transactions.

             (e) Company Information. The Purchaser has had an opportunity to
        discuss the Company's business, management and financial affairs with
        directors, officers and management of the Company and has had the
        opportunity to review the Company's operations and facilities. The
        Purchaser has also had the opportunity to ask questions of and receive
        answers from, the Company and its management regarding the terms and
        conditions of this investment.

        4.4. LEGENDS. Each certificate representing the Shares will be endorsed
with the following legends:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND
        ARE "RESTRICTED SECURITIES" AS DEFINED IN RULE 144 PROMULGATED UNDER THE
        ACT. THE SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE
        DISTRIBUTED EXCEPT (I) IN CONJUNCTION WITH AN EFFECTIVE REGISTRATION
        STATEMENT FOR THE SHARES UNDER THE ACT, (II) IN COMPLIANCE WITH RULE 144
        OR (III) PURSUANT TO AN OPINION OF COUNSEL TO THE COMPANY THAT SUCH

        Securities Exchange Act of 1934, as amended (the "Exchange Act").

             (c) so long as the Purchaser owns any Shares, to furnish to the
        Purchaser within a reasonable time upon a written request by the
        Purchaser, a written statement by the Company as to its compliance with
        the reporting requirements of said Rule 144 (at any time after ninety
        (90) days after the effective date of the first registration statement

        public) and of the Exchange Act (at any time after it has become subject
        to such reporting requirements), a copy of the most recent annual or

such first registration of the Company's securities, agrees not to sell, make
any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any Shares or any shares of Common Stock of the Company or any
securities convertible into or exercisable or exchangeable for Shares or Common

underwriters, as the case may be, for 180 days from the effective date of such
registration; provided, however, that all executive officers, directors and 2%
or greater shareholders of the Company must enter into similar lock-up
agreements as well. The Purchaser agrees that the Company may instruct its
transfer agent to place stop transfer notations in its records to enforce the

                             SCHEDULE OF EXCEPTIONS

        Pursuant to Section 3 of the Common Stock Purchase Agreement (the
"Agreement") dated as of August 31, 2000, by and between the Company and the
Purchaser, the Company hereby delivers this Schedule of Exceptions to the
representations and warranties of the Company given in the Agreement. Each
section number in this Schedule of Exceptions corresponds to the section numbers
in the Agreement; however, any information disclosed herein under any section
number shall be deemed to be disclosed and incorporated in any other section
number of the Agreement where such disclosure would be appropriate. Any
capitalized terms not otherwise defined herein shall have the meaning ascribed
to them in the Agreement.

3.1  Organization, Good Standing and Qualification

        No Exceptions.

3.2  Authorization; Binding Obligations

        No Exceptions.

3.3  Compliance with Other Instruments

        No Exceptions.

3.4  Litigation

        On July 6, 2000, a complaint was filed in the United States District
Court for the Northern District of California captioned "Julia Butterfly Hill v.
AT&T Corporation, a New York corporation; AT&T Wireless Services, Inc., a
Delaware corporation; OmniSky Corporation, a Delaware corporation; TWBA
Chiat/Day, a Delaware corporation; and Does I-XX, inclusive." The complaint
alleges, among other things, false endorsement and false designation of origin;
false and misleading advertising and misappropriation of likeness and image. We
have not yet been served with the complaint. We intend vigorously to defend
ourselves and believe that the claims alleged are without merit. We do not
believe that the resolution of this matter will have a material effect on our
financial condition or results of operations.

        Except as described in the previous paragraph, we are not currently
subject to any material legal proceedings. We may from time to time, however,
become a party to various legal proceedings arising in the ordinary course of
our business. We also may be indirectly affected, as we discussed above under
the subsection entitled "Government regulation" by administrative or court
proceedings or actions in which we are not involved but which have general
applicability to the Internet or wireless industries.

                             [FORM OF LEGAL OPINION]

                                 [Closing Date]

To the Purchaser of Common Stock of
OmniSky Corporation pursuant to the Common
Stock Purchase Agreement dated as of the date hereof

Ladies and Gentlemen:

        Reference is made to the Common Stock Purchase Agreement dated as of
August 31, 2000 (the "Purchase Agreement") by and among OmniSky Corporation, a
Delaware corporation (the "Company"), and America Online, Inc. (the
"Purchaser"), which provides for the issuance and sale by the Company to the
Purchaser of an aggregate of up to ____________ shares of Common Stock (the
"Shares") at a purchase price of $____ per share for an aggregate purchase price
of up to approximately $_________. This opinion is rendered to you pursuant to
Section 5.1(e) of the Purchase Agreement and all terms used herein have the
meanings defined for them in the Purchase Agreement unless otherwise defined
herein.

        We have acted as counsel for the Company in connection with the
negotiation, execution and delivery of the Purchase Agreement and the issuance
of the Shares to the Purchaser as contemplated by the Purchase Agreement. As
such counsel, we have made such legal and factual examinations and inquiries as
we have deemed advisable or necessary for the purpose of rendering this opinion,
and we have examined originals or copies of the following:

        (a)     The Certificate of Incorporation of the Company (the
                "Certificate");
        (b)     The Bylaws of the Company;
        (c)     The resolutions adopted by the Board of Directors of the Company
                and the stockholders of the Company with respect to the
                transactions contemplated by the Purchase Agreement;
        (d)     The certificates representing the shares of the Company's Common
                Stock issued to the Purchaser on the date hereof;
        (e)     Executed counterparts of the Purchase Agreement;
        (f)     The officer's certificate dated the date hereof delivered to
                you;
        (g)     The certified or official bank checks or evidence of wire
                transfers payable to the Company delivered by the Purchaser on
                the date hereof as consideration for the sale of the Shares; and
        (h)     The certificates of certain state authorities and filing
                officers, copies of which are being delivered to you on the date
                hereof.

<PAGE>   17

        As used in this opinion, the expressions "to our knowledge," "known to
us," and "of which we are aware" with reference to matters of fact means that,
after an examination of documents made available to us by the Company and after
inquiries of officers of the Company, we find no reason to believe that the
opinions expressed herein are factually incorrect. Further, the expressions "to
our knowledge," "known to us," "of which we are aware" or similar language with
reference to matters of fact refers to the current actual knowledge of the
attorneys of this firm who have worked on matters for the Company solely in
connection with the Purchase Agreement. We have not undertaken any independent
investigation to determine the existence or absence of any fact, and no
inference as to our knowledge of the existence or absence of any fact should be
drawn from our representation of the Company or the rendering of the opinions
set forth below.

        For purposes of this opinion, we are assuming that each party (other
than the Company) to the Purchase Agreement has all requisite power and
authority, and has taken any and all necessary corporate or partnership action,
to execute and deliver the Purchase Agreement to which it is a party and to
effect any and all transactions related or contemplated thereby, and that each
of you duly and validly executed and delivered the Purchase Agreement. We are
also assuming that the representations and warranties made by the Purchaser and
the Company under the Purchase Agreement are true and correct, and that the
Purchaser has purchased the Shares for value, in good faith and without notice
of adverse claims within the meaning of the Delaware Uniform Commercial Code.

        The opinions, hereinafter expressed are subject to the following
additional exceptions, qualifications, limitations and assumptions:

        We express no opinion as to (i) the effect of applicable bankruptcy,
insolvency, reorganization, liquidation, conservatorship, readjustment of debt,
moratorium or other similar laws affecting the rights of creditors or (ii) the
provisions of the Purchase Agreement relating to indemnity or contribution.

        We express no opinion as to the effect of rules of law governing
specific performance, injunctive relief or other equitable remedies (regardless
of whether any such remedy is considered in a proceeding at law or in equity) or
as to the effects of public policy on the enforceability of any provision of any
agreement.

        We express no opinion as to compliance with applicable anti-fraud
provisions of federal or state securities laws.

        We have assumed the genuineness of all signatures on original documents,
the authenticity of all documents submitted to us as originals, the conformity
to original documents of all copies submitted to us as copies thereof, the legal
capacity of natural persons, and the due execution and delivery of all documents
(except as to due execution and delivery by the Company) where due execution and
delivery are a prerequisite to the effectiveness thereof.

                                        2
<PAGE>   18

        Our opinion set forth in paragraph 1 below is based solely on the
certificate referenced above as to the legal existence and corporate and tax
good standing of the Company in the state of Delaware.

        This opinion is subject to the effect of statutes, principles of equity
and court decisions providing (i) that certain covenants and provisions of
agreements are unenforceable where enforcement of such covenants or provisions
under the circumstances would violate the enforcing party's implied covenant of
good faith and fair dealing and (ii) that a court may refuse to enforce, or may
limit the application of, a contract or any clause thereof that the court finds
to be unconscionable or contrary to public policy.

        We have not reviewed, and express no opinion on, (i) financial covenants
or similar provisions requiring financial calculations or determinations to
ascertain whether there is any such conflict, (ii) provisions relating to the
occurrence of a "material adverse event" or words of similar import or (iii)
parol evidence bearing on interpretation or construction.

        The opinions expressed herein are limited in all respects to existing
laws, rules and regulations of the State of California, the General Corporation
Law of the State of Delaware, as amended (the "DGCL") and applicable United
States federal laws, rules and regulations. Furthermore, we have made no inquiry
into, and express no opinion with respect to, any federal or state statute, rule
or regulation relating to any tax, antitrust, land use, safety, environmental,
hazardous material, patent, copyright, trademark or trade name matter, as to the
statutes, regulations, treaties or common laws of any other nation, state or
jurisdiction, or the effect on the transactions contemplated in the Purchase
Agreement of noncompliance under any such statutes, regulations, treaties or
common laws. We further disclaim any opinion as to any statute, rule,
regulation, ordinance, order or other promulgation of any regional or local
governmental body or as to any related judicial or administrative opinion.

        Our opinions relate solely to the express provisions of the Purchase
Agreement and the exhibits referred to therein and attached thereto and we
express no opinion as to any other oral or written agreements or understandings
between the Company or the Purchaser.

        Provisions of the Purchase Agreement requiring that waivers must be in
writing may not be binding or enforceable if a non-executory oral agreement has
been created modifying any such provision or an implied agreement by trade
practice or course of conduct has given rise to a waiver.

        Based upon and subject to the foregoing, and subject in all respects to
the disclosure on the Schedule of Exceptions attached to the Purchase Agreement,
we are of the opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware. The Company has the requisite
corporate power and authority to own the properties and assets owned by it and
to carry on its business as presently conducted.

2. The Company has all requisite legal and corporate power and authority to
execute and

                                        3
<PAGE>   19

deliver the Purchase Agreement, to sell and issue the shares of Common Stock to
the Purchaser as contemplated by the Purchase Agreement and to carry out and
perform its obligations under the terms of the Purchase Agreement.

3. The authorized capital stock of the Company consists of 200,000,000 shares of
Common Stock, ____________ of which are issued and outstanding, and 10,000,000
shares of Preferred Stock, none of which is outstanding. All issued and
outstanding shares have been duly authorized, validly issued, fully paid, and
nonassessable and have been issued in compliance with the registration and
qualifications requirements of all applicable securities laws. Upon the
issuance, sale, and delivery for the consideration stated in the Purchase
Agreement, the shares of Common Stock being issued and sold to the Purchaser on
the date hereof shall be duly authorized, validly issued, fully paid, and
nonassessable, shall have been issued in compliance with the registration or
qualification requirements of all applicable securities laws (but excluding
jurisdictions outside the United States); provided, however, that the shares of
Common Stock may be subject to restrictions on transfer under state and/or
federal securities laws. To our knowledge, except for rights described in the
Purchase Agreement (including the Schedule of Exceptions) or in the Prospectus
or the Certificate, there are no other options, warrants, conversion privileges
or other rights presently outstanding to purchase or otherwise acquire any
authorized but unissued shares of capital stock or other securities of the
Company, or any other agreements to issue any such securities or rights.

4. All corporate action on the part of the Company, its directors and
stockholders necessary for the authorization, execution, delivery and
performance of the Purchase Agreement by the Company, and the authorization,
sale, issuance and delivery of the Common Stock to the Purchaser pursuant to the
Purchase Agreement and the Certificate, and the performance of the Company's
obligations under the Purchase Agreement has been taken. The Purchase Agreement,
when executed and delivered by the parties thereto, shall constitute a valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms.

5. The execution, delivery and performance of the terms of the Purchase
Agreement and the issuance of the Common Stock to the Purchaser pursuant to the
Purchase Agreement do not violate (i) any provision of the Company's Certificate
or Bylaws, or (ii) to our knowledge, any law, statute, rule or regulation of the
United States or the State of California.

6. Subject to the accuracy of the Purchaser's representations in Section 4 of
the Purchase Agreement, we are of the opinion that the offer, sale and issuance
of the Common Stock to the Purchaser in conformity with the terms of the
Purchase Agreement and the Certificate constitute transactions exempt from the
registration and qualification requirements of Section 5 of the Securities Act
of 1933, as amended, the laws of the State of California, and the DGCL.

               (a) COMMERCIAL LAUNCH. Subject to the satisfactory completion by
each of AOL and OmniSky of the quality assurance procedures to be set forth by
AOL in Exhibit H,

                                      -4-
<PAGE>   5

AOL and OmniSky shall each use their commercially reasonable efforts to complete
the Launch on or about March 1, 2001, but in no event later than June 1, 2001.

               (b) OMNISKY SERVICE. No fewer than sixty (60)days prior to the
Launch, subject to the terms and conditions of this Agreement, AOL shall provide
OmniSky with the AOL Links. In connection with the Launch, OmniSky and AOL shall
provide OmniSky Subscribers with the OmniSky UI that contains the features and
functionality set forth on Exhibit C; the location and content of those portions
of such OmniSky UI that contain such AOL Links, or any other AOL Content, shall
be subject to AOL's prior written consent, which shall not be unreasonably
withheld. OmniSky shall ensure that the AOL Links shall receive comparable
placement, appearance, and prominence in connection with any changes to the
OmniSky Service.

               (c) CUSTOMIZED SERVICE. On and after the Launch, throughout the
Term, OmniSky shall provide all users of the OmniSky Installer with the option
(the "Customization Option") through a splash screen (the form and content of
which shall be determined by AOL in its sole discretion, subject to technical
limitations) (the "SPLASH SCREEN") to employ a user interface for the OmniSky
Service that has been customized by OmniSky for AOL (the "Customized UI"). The
software and functionality necessary for the Customization Option shall be
contained on the OmniSky Installer shipped on or after the Launch, throughout
the Term. In addition, on and after the Launch, throughout the Term, OmniSky
will provide and promote on its website a downloadable software update that
contains the software and functionality necessary to provide Users with the
Customization Option. On and after the Launch, throughout the Term, OmniSky will
also provide the software updates referred to in the preceding sentence to AOL,
at no cost to AOL, for distribution by AOL, in its sole discretion, through the
AOL Properties. The Customized UI shall incorporate the features and
functionalities set forth on Exhibit D and shall be developed by OmniSky (the
"Customized Service"), subject to AOL's prior written consent. Without limiting
the foregoing, any material changes to the Customized UI (including, without
limitation, any changes to the number, placement, or prominence of the primary
links, features and/or functionalities) shall be subject to AOL's prior written
consent. OmniSky shall perform all development work necessary in connection with
such software update(s), Customized Service and Customized UI at no cost
whatsoever to AOL, and AOL shall reasonably cooperate with OmniSky in connection
therewith. Without limiting the foregoing, Omnisky shall ensure that no splash
screens, solicitations or offers for third party customized services shall
appear on the OmniSky Installer until and unless such user has first
affirmatively opted out of receiving the Customized UI in the Splash Screen.
OmniSky acknowledges that the Customized Service will only be useable by AOL
Subscribers or registered users of other AOL Properties (as determined by AOL in
its sole discretion), subject to terms and conditions (e.g., end-user agreement)
designated by AOL, which agreement shall be subject to OmniSky's prior written
consent, which shall not be unreasonably withheld.

               (d) LINKS. Unless and until changed by AOL in its sole discretion
in accordance with the terms of this Agreement, the AOL Links used with the
OmniSky Service or

                                      -5-
<PAGE>   6

the Customized Service pursuant to this Agreement shall include only those
hyperlinks to be provided by AOL after the Effective Date and incorporated as
part of Exhibit A; provided that AOL shall determine at all times the
destination page or other AOL Content areas to which such AOL Links point. The
Parties shall mutually agree on any necessary processes to effect all such
changes designated by AOL. Without limiting the foregoing, OmniSky shall not
provide any links other than the AOL Links to any AOL Software, AOL Properties
or AOL Content in any manner whatsoever.

               (e) ADDITIONAL FEATURES AND FUNCTIONALITIES. AOL and OmniSky
shall, in good faith, after the date hereof, enter into discussions with respect
to additional features and functionalities that may be introduced to the OmniSky
Service or the Customized Service, including, without limitation, wireless
synchronization and advanced forms of notification and location-based services;
provided, however, that the terms and conditions of any such features or
functionalities, and the costs and expenses related to the development of such
features or functionalities, shall be mutually agreed upon by AOL and OmniSky
and neither Party shall have any obligation to effect any such changes unless
and until mutual agreement on the terms and conditions thereof has been reached.
In the event, however, that OmniSky, independent of its obligations under this
Agreement, develops and markets any new features and functionalities (including,
without limitation, devices and/or networks) for the OmniSky Service (including
any of the aforementioned new features or functionalities), (i) OmniSky will use
commercially reasonable efforts (and in connection therewith will ask third
parties in good faith for waiver of any applicable non-disclosure agreements
necessary) to provide AOL with (A) no less than 90 days advance notice of the
commercial release date of any and all features and/or functionalities to the
OmniSky Service, and OmniSky shall provide as much advance notice as is
reasonably practicable under the circumstances and (B) a regularly updated
schedule of such commercial release dates, subject to the aforementioned
limitations and (ii) OmniSky shall make such features and functionalities
available to AOL as early as and on terms and conditions, taken as a whole, that
are no less favorable than those offered to any third party; provided, however,
that with respect to any such new devices or networks, OmniSky shall offer such
devices or networks to AOL pursuant to the terms and conditions of this
Agreement if such terms are more favorable than those offered to any third
party. Notwithstanding the foregoing, AOL shall retain the right at all times to
decide, in its sole discretion, whether to include such devices or networks
within the scope of this Agreement, and shall have no obligation whatsoever to
so include such devices or networks.

               3. LICENSING. Subject to the terms and conditions of this
Agreement, the Parties hereto grant each other the following licenses:

               (a) AOL INTELLECTUAL PROPERTY.

Section 10(b), AOL may, upon forty-eight (48) hours prior written notice,
suspend or terminate (to the extent technically feasible) OmniSky's right to
display or distribute any AOL Software, AOL Content, AOL Brand Features or AOL
Links if: (1) AOL reasonably determines in good faith that OmniSky has misused

AOL Links, as applicable. Without limiting the foregoing, AOL shall have the
right to terminate this Agreement upon notice to OmniSky in the event of more

marketing and promotional efforts related to this Agreement. Notwithstanding
Section 10(b), OmniSky may suspend or terminate AOL's right to use, reproduce,
distribute or display the OmniSky Brand Features offline if OmniSky reasonably
determines in good faith that AOL has misused or misappropriated the OmniSky

use of its Marks. Each of such Parties further agrees to supply the other Party,
upon request, with a reasonable number of samples of any materials publicly
disseminated by such Party which utilize the other Party's Marks. Each of such
Parties shall also comply with all applicable laws, regulations and customs and
obtain any required government approvals pertaining to use of the other Party's

providing notification.

               4. OWNERSHIP.

               (a) OMNISKY INTELLECTUAL PROPERTY. AOL acknowledges and agrees

thereto, solely in connection with the AOL Links, as expressly authorized under
this Agreement. In connection therewith, OmniSky shall distribute and sublicense
the AOL Software pursuant to AOL's then current standard form of shrink-wrap
license agreement. Without limiting the foregoing, (i) any and all such OEMs
shall be required to agree to AOL's standard software license agreement with
respect to such AOL Software prior to any distribution or other use of the AOL
Software by such OEMs; and (ii) all such resellers shall be expressly prohibited
from any redistribution of or modification to all AOL Software. OmniSky shall

writing by AOL. Neither Party will alter, reverse-engineer, decompile or
disassemble software provided by the other Party, or otherwise attempt to
reconstruct the source code of such software, in any manner whatsoever
(including the AOL Software) without the prior written consent of the other
Party.

        (i) OmniSky shall not develop, promote, integrate, or distribute any

Members, or otherwise use the AOL Namespace or the ICQ Namespace.

        (ii) OmniSky will not integrate, or enter into an agreement to integrate
into any of the Devices or other products developed by or on behalf of OmniSky,

of this Agreement for which AOL shall have the immediate right to terminate this
Agreement upon notice to OmniSky. Without limiting foregoing, except for the
rights expressly granted to OmniSky by AOL hereunder, AOL hereby retains all of
its rights in and to the AOL Content, AOL Links, AOL Brand Features and AOL

however, shall prevent or limit AOL or OmniSky from communicating directly with
Users who use AOL Content or AOL Properties, except as set forth in this
Agreement.

                      (iii) NON-SOLICITATION. Without limiting and in addition
to the provisions of Sections 4(e)(i-ii) above, during the Term of this
Agreement and for the two-year period following the expiration or termination of
this Agreement, using information obtained in connection with this Agreement,
neither Omnisky nor its agents shall use or be permitted to use the AOL
Properties (including, without limitation, the e-mail network contained therein)
to solicit AOL Members when that solicitation is for the benefit of an AOL
Competitor. More generally, Omnisky will not send unsolicited, commercial e-mail
(i.e., "spam") through or into AOL's products or services, absent a Prior
Business Relationship. For purposes of this Agreement, a "PRIOR BUSINESS
RELATIONSHIP" will mean that the AOL Member to whom commercial e-mail is being
sent has voluntarily either (i) engaged in a transaction with Omnisky or (ii)
provided information to Omnisky through a contest, registration, or other
communication, which included clear notice to the AOL Member that the
information provided could result in commercial e-mail being sent to that member
by Omnisky or its agents. Any commercial e-mail to be sent through or into AOL's
products or services shall also be subject to AOL's then-standard restrictions
on distribution of bulk e-mail (e.g., related to the time and manner in which
such e-mail can be distributed through or into the AOL product or service in
question).

                      (iv) COLLECTION, USE AND DISCLOSURE OF MEMBER INFORMATION.

obtained from AOL Members under this Agreement ("MEMBER INFORMATION") complies
with (i) all applicable laws and regulations and (ii) AOL's standard privacy
policies, as made available to OmniSky during the Term of this Agreement.
Omnisky will not disclose Member Information collected hereunder to any third
party in a manner that identifies AOL Members as end users of an AOL product or
service or use Member Information collected under this Agreement to market an
AOL Competitor .

                      (v) USER RIGHTS. Users of AOL Properties and the AOL
Software on Devices will be subject to AOL's standard terms and conditions of
use and nothing contained in this Agreement shall affect or otherwise modify
those standard terms and conditions.

               5. PAYMENTS AND REVENUE ALLOCATION. Any payments to a Party and
any revenue allocation between the Parties shall be distributed as set forth on
Exhibit E; provided,

                                      -10-
<PAGE>   11

that such payments and revenue allocations shall be, taken as a whole, no less
favorable to AOL than to any third party.

               6. OTHER MATTERS.

               (a) PUBLICITY. Neither Party may make any public announcement
about the existence of or terms covered by this Agreement without the other
Party's prior written consent; provided, however, that this Agreement may be
filed with the Securities and Exchange Commission to the extent that counsel for
either Party determines that this Agreement is required by the rules of the
Securities and Exchange Commission to be so filed. Subject to the foregoing, AOL
may, in its sole discretion, announce the relationship set forth in this
Agreement. If a Party is required by law to make any such disclosure, it must
first provide to the other Party the content of the disclosure, the reasons that
such disclosure is required by law, and the time and place that the disclosure
will be made. Notwithstanding the foregoing, each Party shall be permitted
during the term of this Agreement, without the other Party's prior consent,
merely to list the other Party as one if its industry partners and to repeat
factual information or statements contained in any mutually agreed-upon press
release or other public statement. Each Party will submit to the other Party,
for its prior written approval, which will not be unreasonably withheld or
delayed, any marketing, advertising, and all other promotional materials related
to the transactions contemplated hereunder or using the other Party's Marks.

               (b) CO-MARKETING. During the Term , OmniSky will prominently
promote, in OmniSky's online and offline advertising, the AOL Content and AOL
Properties available through the OmniSky Service and Customized Service,
subject, to the extent applicable, the provisions of any co-operative
advertising agreements or arrangements to which OmniSky may otherwise be a
party, and subject to AOL's prior written consent and applicable guidelines as
made available to OmniSky by AOL. OmniSky will not promote third party content
provider's properties more prominently or frequently than it promotes AOL
Content and AOL Properties, taking into consideration the aggregate of OmniSky's
promotional efforts. OmniSky will include AOL branding on all OmniSky retail
boxes (distributed in connection with the OmniSky Service or the Customized
Service) in a manner mutually agreed upon, and subject to AOL's prior written
consent and applicable guidelines, and, at AOL's option and expense, OmniSky
will include an AOL Classic disc, or other AOL Software designated by AOL in its
sole discretion (provided that only a single disc shall be required to be
included), within all OmniSky retail boxes (distributed in connection with the
OmniSky Service or the Customized Service), all associated documentation
provided by AOL with respect to the AOL Software, if requested by AOL in its
sole discretion.

               (c) USER EXPERIENCE: Subject to the Channel and Sub-Channel
placement set forth in Exhibits C and D, AOL and OmniSky will coordinate access
to AOL Properties and AOL CONTENT and other aspects of the User experience;
provided, that AOL will maintain sole editorial control over the AOL Properties
and AOL Content and the terms of use thereof, including without limitation, the
dialogues and other information presented to the User within the

                                      -11-
<PAGE>   12

AOL Properties and AOL Content. AOL and OmniSky will mutually agree to a process
of quality assurance and deployment of AOL Content and AOL Properties on the
OmniSky Service and the Customized Service during the term of this Agreement, to
be attached and incorporated hereto as EXHIBIT H by AOL after the Effective
Date, prior to Launch. Without limiting the foregoing, throughout the Term
OmniSky shall provide to AOL no fewer than thirty (30) devices (e.g., modems)
which access the OmniSky Service (at no charge whatsoever to AOL for such modems
or the OmniSky Service) for use by AOL development, quality assurance and
management personnel.

               (d) SERVICE LEVELS. Prior to Launch, the Parties shall mutually
agree on service level agreements with respect to the activities contemplated in
this Agreement (the "SLAs"). The SLAs shall include, without limitation, the
following provisions: (i) OmniSky shall provide reasonable technical support to
AOL and its developers and contractors at no cost to AOL in connection with this
Agreement; provided that AOL shall pay OmniSky on an NRE basis (on terms no less
favorable than those provided to any third party by OmniSky) in connection with
additional customization to the Customized Service not contemplated in this
Agreement; (ii) OmniSky will reasonably support AOL's alpha and beta testing
efforts for AOL applications and content (including the AOL Content); and (iii)
OmniSky will reasonably assist AOL, using good faith efforts, with getting
service coverage extended to AOL's developers' location in Irvine, California
for the OmniSky Service and the Customized Service.

               (e) REGULATORY. OmniSky, will be responsible for compliance at
all times with all applicable regulatory and other operational requirements
relating to the OmniSky Service, the Customized Service, and the wireless
network utilized in connection with delivery of the OmniSky Service and the
Customized Service.

               (f) OTHER AGREEMENTS. OmniSky agrees that if OmniSky (i) offers
any third party content provider placement on the OmniSky UI (including, but not
limited to, presentation of such provider's name, icon or link) on a
higher-level or new Channel(s) or Sub-Channel(s) than AOL or (ii) customizes,
co-brands or develops a private label version of OmniSky's user interface for a
third party content provider (e.g., similar to the Customized Service), then AOL
shall, in the case of clause (i), be given the opportunity to obtain equivalent
exposure on such higher-level and/or new Channel(s) or Sub-Channel(s) or, in the
case of clause (ii), be given the opportunity to have the Customized Service
appropriately modified by OmniSky (i.e., equivalent customization, co-branding
and/or a private label service, at AOL's option), in each case upon no less
favorable terms and conditions, taken as a whole, as may be agreed to with such
other content provider; provided that, this Section 6(f) shall not apply to
contractual arrangements existing on the Effective Date between OmniSky and
third party content providers. OmniSky will in all cases market the Customized
Service at the lowest price, modem cost and with the most favorable warranty and
guarantee policies as those which apply generally to the OmniSky Service. In no
case will OmniSky charge Users a premium for use of the Customized Service
compared to the OmniSky Service.

                                      -12-

OmniSky will bundle the AOL Software designated by AOL on CD-ROMs containing the
OmniSky Installer; such AOL Software shall be no larger than one hundred (100)
megabytes in the aggregate. During the OmniSky installation process, all Users
will be presented with a Splash Screen that asks if they wish to install AOL
Classic and AOL Instant Messenger (or other AOL Software designated by AOL), and
that provides live links, approved and/or supplied by AOL in advance, to the
applicable AOL installation pages for such AOL Software. For each new, qualified
AOL Classic subscriber acquired by OmniSky pursuant to this Section, AOL will
pay AOL's standard bounty to OmniSky, in accordance with the then standard terms
and conditions set forth at http://affiliate.aol.com/affiliate/welcome.adp.

               8. INDEMNIFICATION.

               (a) OmniSky. OmniSky will indemnify, defend and hold harmless AOL
and its employees, officers, directors, representatives, and agents, against any
third party claim, demands, liabilities, costs, expenses, suit, action, or other
proceeding (collectively, "LIABILITIES") brought against such parties based on
or arising from (i) a claim brought by any third party alleging that the OmniSky
Brand Features, OmniSky UI, Customized UI, OmniSky Service, Customized Service
(and/or any technology used to provide the OmniSky Service or Customized
Service) or OmniSky Installer as provided by OmniSky, infringes in any manner
any copyright, trademark, service mark, patent, trade secret, or other
intellectual property right of such party or (ii) a breach by OmniSky of the
duties, representations and warranties contained in Section 7(a).
Indemnification under this Section 8(a) shall be AOL's sole and exclusive remedy
and OmniSky's sole and exclusive liability, for any infringement referred to in
clause (i).

               (b) AOL. AOL will indemnify, defend and hold harmless OmniSky and
its employees, officer, directors, representatives, and agents, against any
Liabilities based on or arising from (i) a claim brought by a third party
alleging that the AOL Brand Features, AOL Software, AOL Content owned and
operated by AOL (excluding any third party content that may be included within
the AOL Content), or the AOL Properties (excluding any third party content that
may be included therein) as provided by AOL, and in all cases solely and to the
extent accessed by Users through the OmniSky Service or the Customized Service
through the AOL Links, infringes in any manner any copyright, trademark, service
mark, patent, trade secret, or other intellectual property right of such party
or (ii) a breach by AOL of the duties, representations and warranties contained
in Section 7(b). Indemnification under this Section 8(b) shall be OmniSky's sole
and exclusive remedy, and AOL's sole and exclusive liability, for any
infringement referred to in clause (i).

               (c) Conditions to Indemnification. For purposes of this Section
8, the Party obligated to provide the indemnity will be referred to as the
"Indemnitor" and the Party receiving the benefit of such indemnity will be
referred to as the "Indemnitee." The Indemnitor's obligations of indemnification
are conditioned on (i) the Indemnitee's reasonably prompt notice to Indemnitor
of any claim, (ii) the Indemnitee permitting the Indemnitor to assume and
control the defense of the action, with counsel chosen by the Indemnitor (who
must be reasonably acceptable to the Indemnitee), (iii) the Indemnitee providing
all reasonably requested information, assistance and authority to Indemnitor in
the defense of the claim, at Indemnitor's expense; and (iv) Indemnitor not
entering into any settlement or compromise of any claim without the Indemnitee's
prior written approval, not to be unreasonably withheld, conditioned or delayed.
The Indemnitor will pay any and all costs, damages and attorneys' fees awarded
against the Indemnitee, and all reasonable expenses incurred by the Indemnitee,
in connection with or arising from any such claim, suit or proceeding. If the
Parties agree to settle a third party claim, neither Party will publicize the
settlement without first obtaining the other Party's written permission, which
permission will not be unreasonably withheld, conditioned or delayed.

               (d) Separate Counsel. Notwithstanding the foregoing, either Party
shall have the right, at its own expense, to employ separate counsel and
participate in the defense of any claim or action arising under this Section 8.

               9. LIMITATION OF LIABILITY.

        EXCEPT WITH RESPECT TO INDEMNIFICATION FOR AMOUNTS PAYABLE TO A THIRD
PARTY ARISING UNDER THE INDEMNIFICATION OBLIGATIONS UNDER SECTION 8 OR LIABILITY
FOR BREACH OF SECTION 14, UNDER NO CIRCUMSTANCES WILL EITHER PARTY BE LIABLE TO
THE OTHER PARTY FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR EXEMPLARY
DAMAGES ARISING OUT OF OR RELATING TO THIS AGREEMENT, EVEN IF THAT PARTY HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, SUCH AS, BUT NOT LIMITED TO,
LOSS OF REVENUE OR ANTICIPATED PROFITS OR LOST BUSINESS.

        EXCEPT FOR LIABILITY ARISING IN CONNECTION WITH THIRD PARTY CLAIMS UNDER
THE INDEMNIFICATION OBLIGATIONS SET FORTH IN SECTION 8 OR LIABILITY FOR BREACH
OF SECTION 14, IN NO EVENT SHALL EITHER PARTY'S AGGREGATE, CUMULATIVE LIABILITY
TO THE OTHER PARTY ARISING OUT OF OR RELATING TO THIS AGREEMENT EXCEED TEN
MILLION U.S. DOLLARS ($10,000,000.00 USD); PROVIDED THAT THE FOREGOING LIABILITY
CAP SHALL EQUAL TWENTY-FIVE MILLION DOLLARS ($25,000,000.00) WITH RESPECT TO
OMNISKY'S LIABILITY TO AOL IN CONNECTION WITH THE CO-BRANDED SERVICE. THE
EXISTENCE OF ONE OR MORE CLAIMS OR SUITS SHALL NOT ENLARGE THE LIMIT. EACH PARTY
ACKNOWLEDGES THAT THE MUTUAL PROMISES CONTAINED HEREIN REFLECT THE ALLOCATION OF
RISK SET FORTH IN THIS AGREEMENT AND THAT EACH PARTY WOULD NOT ENTER INTO THIS
AGREEMENT WITHOUT THESE LIMITATIONS ON LIABILITY.

               10. TERM AND TERMINATION.

               (a) TERM. This Agreement commences on the Effective Date and
will, unless sooner terminated as provided below or as otherwise agreed, remain
effective for three (3) years. The term shall automatically renew upon
expiration for two additional one (1) year terms, unless AOL provides OmniSky
with written notice of its intent to terminate within 30 days of expiration of
the initial term of this Agreement or any subsequent renewal term; provided,
however, that if AOL has not elected to offer the Co-Branded Service, as
referred to in Section 15, on or prior to the sixtieth day preceding the third
anniversary of the Effective Date, then, in such event, either Party may elect
not to renew this Agreement upon 30 days prior written notice to the other
Party. (The initial term, together with any renewal terms, collectively, the
"TERM".)

               (b) TERMINATION. This Agreement may be terminated by either Party
immediately upon receipt of notice if the other Party: (i) becomes insolvent;
(ii) files a petition in

                                      -16-
<PAGE>   17

bankruptcy; (iii) makes an assignment for the benefit of its creditors; (iv)
breaches any of its obligations under this Agreement in any material respect,
which breach is not cured within thirty (30) days following receipt of written
notice by such Party (except that the foregoing 30 day cure period does not
apply to a termination of the Agreement pursuant to Section 3(a)(iv)); or (v)
breaches any of its material obligations set forth in the SLAs, and fails to
cure such breach(s) in accordance with the cure periods set forth in the SLAs.

               (c) EFFECT OF TERMINATION. The provisions of Sections 1, 3, 4(d),
4(e)(iii), 6(a), 6(e), 7, 8, 9, 10(c), 10(d), 11, 12, 14, and 18 of the main
body of the Agreement, and Section 2(e) of Exhibit E, will survive any
termination or expiration of this Agreement. Upon a termination or expiration of
this Agreement, each of OmniSky and AOL agree to immediately cease using,
displaying, reproducing or distributing the AOL Brand Features, AOL Content, AOL
Software, AOL Properties (in the case of OmniSky, except as required in the
transition period described in Section 10(d) below), or the OmniSky Brand
Features (in the case of AOL); provided, however, that AOL understands that
OmniSky will not be able to recover installer disks that have been distributed
on or prior to the date of termination and that AOL Brand Features that have
been installed on the Devices will continue to appear on such Devices
notwithstanding any termination of this Agreement. Additionally, upon the
expiration or termination of the Agreement, each Party will, upon the written
request of the other Party, return or destroy (at the option of the Party
receiving the request) all Confidential Information, documents, manuals and
other materials provided by the other Party.

               (d) CONTINUATION OF OMNISKY SERVICE UPON EXPIRATION. Upon the
expiration or termination, of the initial term or a renewal term of this
Agreement, OmniSky shall continue, at AOL's option, to provide OmniSky Service
and/or Customized Service, as the case may be, to Users pursuant to the terms of
this Agreement for a period of time at least equal to (i) 12 months, in the
event that the aggregate number of subscribers to the Customized Service and the
Co-Branded Service is less than 100,000 on the date of such expiration or (ii)
24 months in all other cases. On and after the effective date of any termination
or expiration of this Agreement, OmniSky shall be entitled, subject to the usage
guidelines for Marks (i.e., AOL Brand Features) set forth in this Agreement, to
reposition or otherwise modify slotting arrangements for AOL Properties or AOL
Content with respect solely to the OmniSky Service (but not the Customized
Service), beginning twelve (12) months after the effective date of such
termination of the Agreement, and in any event, at any time after the conclusion
of any applicable transition period pursuant to this Section 10(d).

               11. EXPENSES. Unless otherwise expressly agreed by the Parties in
writing, each Party shall bear its own costs and expenses in performing its
obligations under this Agreement.

                                      -17-
<PAGE>   18

               12. NOTICES. All notices, requests and other communications
called for by this Agreement will be deemed to have been given as of the day
they are received either by messenger, or delivery service, or deposited in the
United States of America mails, postage prepaid, certified or registered, return
receipt requested, and addressed to the address set forth on the signature page
hereto, or to such other addresses as either Party may specify to the other from
time to time. Notice by any other means will be deemed made when actually
received by the Party to which notice is provided.

               13. CHANGE OF CONTROL. AOL shall have the right to terminate this
Agreement, without liability, at any time within 180 days after consummation of
an OmniSky Change of Control. In the event of any termination of this Agreement
pursuant to this Section 13, OmniSky shall pay to AOL (i) $5 million if AOL has
not provided OmniSky with notice of its election that it seeks to receive the
Co-Branded Service (the "CO-BRANDED ELECTION") on or prior to the date of such
termination or (ii) $15 million if AOL has provided Omnisky notice of such
Co-Branded Election on or prior to the date of such termination, in each case,
within ten days after the effective date of any such termination. For purposes
of this Section 13, a "Change of Control" shall mean (a) The consummation of a
reorganization, merger or consolidation or sale or other disposition of
substantially all of the assets of a party in which OmniSky is not the surviving
entity or a transaction in which the holders of a majority of the outstanding
stock of such Party prior to such merger or consolidation are not the holders of
a majority of the outstanding stock after such merger or consolidation, or (b)
the acquisition by any individual, entity or group (within the meaning of
Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended)
of beneficial ownership (within the meaning of Rule 13d-3 promulgated under such
Act) of, in the aggregate, more than 50% of either (i) the then outstanding
shares of common stock of such Party; or (ii) the combined voting power of the
then outstanding voting securities of such Party entitled to vote generally in
the election of directors.

               14. CONFIDENTIALITY.

               (a) CONFIDENTIAL INFORMATION. "Confidential Information" of a
Party means any information, in which such Party has rights, disclosed by that
Party to the other pursuant to this Agreement which is in written, graphic,
machine readable or other tangible form and is either marked "Confidential,"
"Proprietary" or in some other manner to indicate its confidential nature, or
under the circumstances surrounding its disclosure, ought to be treated by the
receiving Party as confidential. Each Party shall treat as confidential all
Confidential Information of the other Party, shall not use such Confidential
Information except as set forth herein, and may disclose Confidential
Information only to its employees or consultants on a need-to-know basis (who
shall be subject to the provisions of Sections 14(a)-(c)). Without limiting the
foregoing, each of the Parties shall use at least the same degree of care which
it uses to prevent the disclosure of its own confidential information of like
importance to prevent the disclosure of Confidential Information disclosed to it
by the other Party under this Agreement.

                                      -18-
<PAGE>   19

               (b) EXCEPTIONS. Notwithstanding the above, neither Party shall
have liability to the other with regard to any Confidential Information of the
other which (a) was in the public domain at the time it was disclosed or has
entered the public domain through no fault of the receiving Party; (b) was known
to the receiving Party, without restriction, at the time of disclosure; (c) is
disclosed with the prior written approval of the disclosing Party; (d) was
independently developed by the receiving Party without any use of the
Confidential Information; or (e) became known to the receiving Party, without
restriction, from a source other than the disclosing Party, without breach of
this Agreement by the receiving Party and otherwise not in violation of the
disclosing Party's rights.

               (c) ADDITIONAL OBLIGATIONS. The receiving Party shall: (i)
refrain from disclosing any Confidential Information of the disclosing Party to
third parties for three (3) years following the date it receives such
Confidential Information, except as expressly provided in this Section 14; (ii)
take reasonable security precautions, at least as great as the precautions it
takes to protect its own confidential information of a similar nature, but no
less than reasonable care, to keep confidential the Confidential Information of
the disclosing Party; (iii) disclose, reproduce, and/or summarize and distribute
Confidential Information of the disclosing Party only in pursuance of its
business relationship with the disclosing Party as expressly provided hereunder;
and (iv) refrain from reverse engineering, decompiling or disassembling any
software code and/or pre-release hardware devices disclosed by the disclosing
Party under the terms of this Agreement.

               (d) GOVERNMENTAL ORDERS. A Party may disclose the Confidential
Information of the other Party to the extent required by the order or
requirement of a court, administrative agency, or other governmental body;
provided, however, that the receiving Party shall provide prompt notice thereof
to the disclosing Party to enable the disclosing Party to seek a protective
order or otherwise prevent or restrict such disclosure.

               (e) This Section intentionally left blank.

               15. CO-BRANDED SERVICES. AOL may elect to offer a Co-Branded
Service, and AOL and OmniSky agree, in such event, to negotiate in good faith
definitive agreements and documentation, reasonably satisfactory to both Parties
(with the goal of entering into such agreements and documentation within thirty
(30) days after the date of AOL's election), providing for the development and
implementation of the Co-Branded Service (the "DEFINITIVE DOCUMENTATION"). AOL
and OmniSky agree that such Definitive Documentation shall have substantially
the terms and conditions set forth on Exhibit F; Sections 1, 3, 4(d)(i-ii),
4(e), 6(a), 6(e), 7, 8, 9, 10, 11, 12, 13, 14, 18 of this Agreement shall
additionally apply to the Co-Branded Service.

               16. AOL MARKETING OF OMNISKY SERVICE. During the Term , OmniSky
agrees to purchase from AOL an aggregate of three million dollars
($3,000,000.00) of online advertising on certain AOL Properties, subject to
AOL's customary terms and conditions

                                      -19-
<PAGE>   20

reasonably satisfactory to OmniSky, and in connection therewith, the Parties
shall mutually agree on two carriage plans with respect to such advertising
(each, a "CARRIAGE PLAN, and collectively, the "CARRIAGE PLANS"). The Parties
shall mutually agree on the first Carriage Plan within thirty (30) days of the
Effective Date with respect to the advertising to be run on the applicable AOL
Properties within the first six months after the Effective Date (the "SIX MONTH
PERIOD") (OmniSky shall not unreasonably withhold its consent with respect to
the Carriage Plans). The Parties shall mutually agree on the second Carriage
Plan within one hundred twenty (120) days after the Effective Date with respect
to the advertising to appear on the applicable AOL Properties during the
eighteen (18) months after the Six Month Period. OmniSky shall pay AOL One
Million Five Hundred Thousand Dollars ($1,500,000.00) within thirty (30) days of
the Effective Date, and an additional payment of One Million Five Hundred
Thousand Dollars ($1,500,000.00) within one hundred twenty (120) days of the
Effective Date, in exchange for such advertising. At AOL's election, OmniSky
will purchase $1.5 million of such online advertising during the first two full
calendar quarters after the Effective Date (i.e., with the advertising to run on
the applicable AOL Properties within the first two such calendar quarters after
the Effective Date) and the remaining $1.5 million of such online advertising
over the next eighteen (18) months after the Six Month Period, to be distributed
evenly on a quarterly basis. OmniSky may purchase such online advertising on any
or all of the AOL Properties listed on Exhibit G or, upon mutual agreement,
other AOL Properties not set forth on Exhibit G. The Parties acknowledge that
any such advertising running at or after Launch will be used to promote the
Customized Service or the availability of the AOL Properties on the OmniSky
Service; all advertising copy and content in connection therewith shall be
subject to AOL's prior written approval (which shall not be unreasonably
withheld).

               17. This Section intentionally left blank.

               18. MISCELLANEOUS.

               (a) INDEPENDENT CONTRACTORS. AOL and OmniSky are independent
contractors and nothing contained in this Agreement is intended or shall be
construed as creating a relationship of principal and agent, employer and
employee, partnership, franchise, or joint venture between the Parties.

               (b) AMENDMENTS. This Agreement shall constitute the binding
agreement of the Parties. This Agreement may not be changed or amended except in
writing dated subsequent to the Effective Date and signed by authorized
representatives of both Parties.

               (c) NO WAIVER. No failure or delay on the part of either Party in
the exercise of any right, power or remedy under this Agreement or under law, or
to insist upon or enforce performance by the other Party of any of the
provisions of this Agreement or under law, shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or remedy preclude
other or further exercise thereof, or the exercise of any other right, power or
remedy; rather the provision, right, or remedy shall be and remain in full force
and effect.

                                      -20-
<PAGE>   21

               (d) ASSIGNMENT. Neither Party shall assign the Agreement or any
right, interest or benefit under the Agreement without the prior written consent
of the other Party, not to be unreasonably withheld. Subject to the foregoing,
the Agreement will be fully binding upon, inure to the benefit of and be
enforceable by the Parties hereto and their respective successors and assigns.
Notwithstanding the foregoing, and without securing such consent, AOL shall have
the right to assign this Agreement and the obligations hereunder to any
successor of AOL by way of merger, consolidation or the acquisition of all or
substantially all of the business and assets of AOL relating to this Agreement,
including, without limitation, in connection with AOL's merger with Time Warner,
Inc.

               (e) SEVERABILITY. If for any reason a court of competent
jurisdiction finds any provision of this Agreement or portion thereof to be
unenforceable, that provision will be enforced to the maximum extent permissible
so as to effect the intent of the Parties and the remainder of this Agreement
will continue in full force and effect. This Agreement has been negotiated by
the Parties and their respective counsel, and will be interpreted fairly in
accordance with its terms and without any strict construction in favor of or
against either Party.

               (f) GOVERNING LAW. The Agreement will be interpreted, construed
and enforced in all respects in accordance with the laws of the Commonwealth of
Virginia except for its conflicts of laws principles.

               (g) TAXES. Each Party shall pay, and be responsible for, any and
all sales taxes, use taxes and any other taxes duly imposed on such Party by any
jurisdiction as a result of: (a) the entry into this Agreement; (b) the
performance of any of the provisions of this Agreement; or (c) the transfer of
any property, rights or any other grant hereunder.

               (h) EXCUSE. Neither of the Parties hereto will be liable for, or
be considered in breach of or default under this Agreement on account of, any
delay or failure to perform as required by this Agreement as a result of strike,
fire, explosion, flood, storm, material shortages, riot, insurrection,
governmental acts, labor conditions, acts of God, war, earthquake or any other
cause which is beyond the reasonable control of such Party; provided that the
nonperforming Party gives reasonably prompt notice under the circumstances of
such condition(s) to the other Party.

               (i) FURTHER ASSURANCES. Each of the Parties hereto will take such
action (including, but not limited to, the execution, acknowledgment and
delivery of documents) as may reasonably be requested by the other Party for the
implementation or continuing performance of this Agreement.

               (j) EXPORT CONTROLS. Each of the Parties hereto will adhere to
all applicable laws, regulations and rules relating to the export of technical
data and will not export or re-export any technical data, any products received
from the other Party or the direct product of such

                                      -21-
<PAGE>   22

technical data to any proscribed country listed in such applicable laws,
regulations and rules unless properly authorized.

               (k) HEADINGS. The captions and headings used in this Agreement
are inserted for convenience only and will not affect the meaning or
interpretation of this Agreement.

               (l) COUNTERPARTS; FACSIMILE. This Agreement may be executed in
counterparts and by facsimile, each of which counterparts will be deemed an
original and all of which together will constitute one and the same document.

               (m) ENTIRE AGREEMENT. This Agreement, including the Exhibits
hereto and any service level agreements executed after the Effective Date,
constitutes the entire understanding and agreement of the Parties hereto with
respect to the subject matter hereof and supersedes all prior and
contemporaneous agreements or understandings between the Parties.

               (n) INJUNCTIVE RELIEF; REMEDIES. Each Party acknowledges a
violation of this Agreement could cause irreparable harm to the other Party for
which monetary damages may be difficult to ascertain or an inadequate remedy.
Each Party therefore agrees that the other Party will have the right, in
addition to its other rights and remedies, to seek and obtain injunctive relief
for any violation by the other Party of such sections. Except where otherwise
specified, the rights and remedies granted to a Party under the Agreement are
cumulative and in addition to, and not in lieu of, any other rights or remedies
which the Party may possess at law or in equity.

               (o) This Section intentionally left blank.

               (p) EXPANSION OF TERRITORY. The Parties acknowledge that the
Agreement shall apply to services (e.g., the OmniSky Service, Customized
Service) provisioned by OmniSky within the United States of America (the
"TERRITORY"), and any other services similar to the OmniSky Service outside the
Territory provided by OmniSky. With respect to similar services provided by
entities related to OmniSky outside the Territory, the Parties shall discuss in
good faith the extension of this Agreement to such areas and services.

-   CONTENT AND SERVICES:

               o  AOL will control the creation, ownership, and economics of the
                  content and services provided through the Service. At AOL's
                  discretion, OmniSky will perform the development (e.g.,
                  development of content templates) work to implement the user
                  interface and customize the channel ontology in accordance
                  with AOL's specifications. OmniSky agrees to customize the

    provided that the applications inter-operate with the OmniSky browser

                          Upon mutual agreement, additional customization of the
                  Service will be performed by OmniSky on a NRE basis, for which
                  OmniSky will charge AOL either (i) commercially reasonable
                  rates or (ii) rates on terms no less favorable than those
                  offered to any other OmniSky partner. The Parties will
                  mutually agree to a process of quality assurance and
                  deployment of content on the Service during the term.

               o  AOL will develop or acquire all content or commerce vertical
                  services to be offered as part of the Service and may offer
                  any such services (including personalized information,
                  location-

<PAGE>   33

                  based services, e-commerce, content, transactions, etc) in its
                  discretion, provided that such services are compatible with
                  the OmniSky service architecture.

               o  OmniSky may present AOL with certain value-added services
                  (including wireless synchronization, advanced forms of
                  notification, and location-based services) that the Parties,
                  on a case by case basis, may mutually decide to implement
                  within the Service.

               o  To the extent that OmniSky introduces new capabilities to its
                  end-users and partners, OmniSky will make such services and/or
                  applications available to AOL as early as and on terms no less
                  favorable than those offered to any other OmniSky end-user or
                  partner.

               o  AOL will sell all advertising (e.g., advertising, slotting
                  fees, sponsorships, content placements) and mobile commerce
                  opportunities.

-   USER EXPERIENCE: AOL and OmniSky will coordinate customization of the
    installation process and other aspects of the Service's user experience,
    provided that AOL will maintain editorial control over the dialogues and
    other information presented to the user.

    ad-serving capabilities into the Service, when available. Should AOL decide
    to integrate OmniSky's advertising capabilities, AOL will sell all
    associated advertising inventory slots.

        B. LAUNCH: The Parties will use best or all reasonable efforts to launch
           the Service within 60 days of AOL providing notice that it wants to
           launch for any particular device/network then supported by OmniSky,
           provided that AOL notifies OmniSky either: 1) within 30 days of
           receiving notice from OmniSky that its service will be available on a
           new device or network (per "Future Networks and Devices" above, or 2)
           after commercial launch of OmniSky's own service for that device or
           network.

        C. BRANDING:

        -  SERVICE. The user interface for the Service will include branding as
           designated by AOL and will include OmniSky ingredient branding (e.g.,
           "AOL Wireless by OmniSky").

        -  MODEMS. If AOL elects to procure wireless modems from OmniSky,
           OmniSky will have the right to brand the modem with the OmniSky
           brand. AOL may purchase modems from a third party in accordance with
           OmniSky's specifications or from OmniSky's approved vendors in which
           case AOL has the right to brand the modems.

        D. MARKETING:

    any necessary artwork and marketing materials to AOL.

<PAGE>   34

        E. AOL may distribute the AOL-branded modems through its retail channels
           upon the implementation of a retail provisioning system.

        F. PACKAGING, FULFILLMENT AND PROVISIONING: OmniSky will create all
           packaging materials in accordance with AOL's specifications. OmniSky
           will provide all provisioning and fulfillment (including to the
           end-user) for the Service and related hardware. In the event AOL
           distributes the modem and Service through its retail channels, AOL
           will provide fulfillment and OmniSky will provision the Service. If
           mutually agreed, OmniSky will fulfill to AOL's retail channels.

        G. WARRANTEES. If AOL purchases OmniSky-branded modems from OmniSky,
           OmniSky will offer Service subscribers a modem warrantee on terms no
           less favorable than those offered to OmniSky Classic customers or
           other OmniSky partners. If AOL purchases the modems from a third
           party (subject to Section C), AOL will be responsible for any
           associated warrantee policy.

        H. RETURNS. If OmniSky fulfills OmniSky-branded modems directly to
           Service end users, OmniSky will offer a return policy with terms no
           less favorable than those offered to OmniSky Classic customers or to
           other OmniSky partners. If OmniSky fulfills OmniSky-branded modems to
           the retail channel, OmniSky will offer a return policy with terms no
           less favorable than those offered to OmniSky Classic channel partners
           and customers. If AOL fulfills modems to the retail channel or to end
           users, AOL will be responsible for any associated return policy.

        I. REACTIVATION. OmniSky will offer Service subscribers a reactivation
           option with terms no less favorable than those offered to OmniSky
           Classic customers or other OmniSky partners.

-   SERVICE SUBSCRIPTION FEES: For each subscriber to the Service, AOL will pay
    OmniSky the least of (i) [***]% of the lowest retail monthly, or its

    offers for fixed fees), price for the OmniSky-branded service, (ii) the
    lowest monthly, or its equivalent, wholesale rate charged by OmniSky to any
    other partner, or (iii) the flat fee per month per subscriber according to

-   The number of subscribers (for the above calculation) is determined on the
    last day of the month for the prior month. Those fees reflect wholesale
    pricing which includes billing and customer service and excludes credit card
    processing fees, merchant bank fees and bad debt expense unless otherwise
    specified.

-   If OmniSky's direct, variable costs to provide the Service decrease by 10%
    or more, AOL will receive the equivalent percentage discount on its
    wholesale rates set forth above. OmniSky will notify AOL of any such cost
    decrease and implement such wholesale rate decrease on a quarterly basis
    (AOL has audit rights).

-   MODEMS: At AOL's option, end users will receive modems in one of two ways:

               i.     AOL can buy modems from third parties (parameters outlined
                      in Section C) in which case AOL will fulfill and OmniSky
                      will provision the modems.

               ii.    AOL can buy modems from OmniSky at OmniSky's lowest
                      wholesale cost from its manufacturers or lowest wholesale
                      price provided to any third party in which case OmniSky
                      will fulfill and provision modems to the end-user.

-   ANCILLARY REVENUES: All advertising (including content slotting fees) and
    mobile commerce revenues directly attributable to the Service will be split
    [***]% to AOL and [***]% to OmniSky. In the event that OmniSky successfully
    refers a content provider to AOL (subject to AOL's prior written approval),
    the advertising (including content slotting fees) and mobile commerce
    revenues directly attributable to the Service will be split [***]% to
    OmniSky and [***]% to AOL.

        -  CONTENT-BASED ADVERTISING. AOL will make commercially reasonable
           efforts to sell advertising on the Service.

-   MARKETING.  AOL will be responsible for marketing the Service.

-   PACKAGING, PROVISIONING AND FULFILLMENT. AOL will reimburse OmniSky for all
    actual and reasonable incremental costs associated with packaging,
    provisioning and fulfillment.

-   SERVICE OPERATIONS AND MAINTENANCE. OmniSky will incur all service
    operations and maintenance costs. OmniSky will also incur all content
    deployment and quality assurance costs.

confidential redacted portion has been omitted and filed separately with the
Securities and Exchange Commission.

-   NOTIFICATION. OmniSky will provide AOL with at least 30 days advance notice
    of any retail price changes for the OmniSky-branded modem or service.
    OmniSky may also approach AOL on less than 30 days notice and seek a
    mutually agreeable response to a competitors retail promotion. (e.g.
    temporary pricing action)

        K. CUSTOMER SUPPORT: At AOL's discretion, OmniSky will provide
           first-tier customer support with hot transfers to AOL in the event of
           any questions specific to the AOL content or services. The Parties
           will agree to a script for customer support in the event OmniSky
           provides customer support. The Parties will work to transition
           customer support to AOL as soon as reasonably practicable.

        L. BILLING: At AOL's discretion, OmniSky will bill the subscriber for
           the Service in AOL's name and will remit all payments from the end
           user to AOL. The Parties will work to transition billing for the
           Service to AOL as soon as reasonably practicable.

        M. REGISTRATION AND SIGN-ON: Subscribers will register (or create an
           account) for the Service using an AOL screen name and password within
           the AOL namespace. OmniSky acknowledges that AOL, in its discretion,
           may require that Service subscribers also be subscribers to another
           AOL service (e.g., the AOL Classic ISP Service). AOL Classic
           end-users will have the ability to sign on using all their AOL
           Classic screen names for use under this service.

        N. SOURCING: AOL and OmniSky will collaborate on modem procurement and
           airtime pricing.

        O. MARKETING COMMITMENTS

AOL will make commercially reasonable efforts to market the Service.
