development will receive 100% of royalties due the other party until 125% of
such development cost is recovered, or as otherwise agreed to by mutual written
consent.

         (c) If the joint chips are sold by either party, the other party will
receive a royalty of 15% on the sales revenues of all such chips. Such royalty
may be adjusted from time to time by the mutual written consent of Mobility and
2C; provided, however, if the joint chips are also developed jointly with Cybex,
Cycom or any of their respective affiliates (collectively, the "Cybex Entities")
then any such royalty payable by Mobility to 2C hereunder shall be divided among
2C and the Cybex Entities as they deem appropriate and as specified in writing
to Mobility by the involved entities (including 2C); it being acknowledged and
agreed that such 15% royalty shall be the maximum aggregate amount payable by

have the right to purchase and sell such chips from the manufacturing foundry at
cost.

         (d) If the joint products are sold by either party, the other party
will receive a royalty of 6% on the sales revenue of all such products;
provided, however, if the joint products are also developed jointly with any
Cybex Entity then any such royalty payable by Mobility to 2C hereunder shall be
divided among 2C and the Cybex Entities as they deem appropriate and as
specified in writing to Mobility by the involved entities (including 2C); it
being acknowledged and agreed that such 6% royalty shall be the maximum
aggregate amount payable by Mobility to 2C and the Cybex Entities for any such
joint product. Such royalty may be adjusted from time to time by the mutual
written consent of Mobility and 2C. Both parties will have the right to
manufacture and sell such products.

         (e) Any technology contributed by a party will be owned 100% by such
contributing party, and may not be used by the non-contributing party for any
purpose other than the joint product and/or joint chip. Any new jointly
developed technology and any associated patents and patent rights will be
jointly owned by the parties, but also may not be used for any purpose other
than the joint product and/or joint chip as provided above without the other
party's consent.

         4.3      Pursuant to the terms of this agreement, 2C agrees to make
available to Mobility, to the extent it has the right to do so, all future
enhancements, variations, modifications, and future generations of 2C Technology
at a royalty rate defined below.

                                       V.

                          ROYALTIES AND LINK PURCHASES

         During the Term, Mobility shall pay to 2C royalties as follows:

         5.1      On all sales by Mobility of any product incorporating any 2C
Technology, 6% of Mobility's sale price of such product. This royalty will not
apply to any products sold by Mobility which are purchased from Cybex Computer
Products Corporation or 2C or its affiliates (including, without limitation,
Cycom, LLC) for resale.

         5.2      Subject to availability (it being acknowledged and agreed that
Mobility shall be treated at least similar to 2C's other customers), 2C and its
affiliates shall offer for sale to Mobility any of their products that
incorporate 2C Technology or Mobility Technology. The price of such product
sales to Mobility will be at a rate no greater than the lowest rate offered to
any third party independent of 2C or its affiliates that purchases the same
product at comparable

                                       3
<PAGE>   4

volumes. Moreover, 2C and its affiliates agree to provide Mobility an
appropriate discount on the pricing for the applicable products if the
applicable 2C or affiliate product incorporates a material amount of Mobility
Technology at terms to be mutually agreed upon in writing.

         5.3      Royalties due under Paragraph 5.1 shall be paid quarterly
within 30 days of the end of each quarter. Payments shall be made by wire
transfer to an account specified in writing at least 30 days prior to the date a
royalty payment is due. Within 30 days after the end of each quarter, Mobility
shall furnish to 2C a report providing the number and types of 2C Technology
sold, the applicable royalty rate, and the total royalty paid.

         5.4      Mobility agrees to make and maintain such books, records and
accounts as are reasonably necessary to verify the royalty payments due 2C under
this Agreement. An independent certified public accountant, selected by 2C, who
agrees to sign a nondisclosure agreement may, upon reasonable notice and during
normal business hours, but no more often than twice each year, audit and inspect
those records of Mobility which are necessary to determine the accuracy of the
royalty payments made to 2C. In the event that the independent audit reveals
that the royalties owed by Mobility for any given quarter are more than 5%
greater than the royalties actually paid by Mobility for that quarter, then in
addition to remitting all outstanding royalties shown to be due under the audit,
all expenses incurred by 2C in conducting the audit shall be paid by Mobility
within 30 days of receiving the auditor's report; otherwise, all expenses
incurred by 2C in conducting the audit shall be borne by 2C.

         5.5      2C intends to develop, at 2C's cost and expense, a new
physical interface transistor chip (the "PI Chip"). 2C agrees that 2C will sell
the PI Chip to Mobility at a price equal to the lower of: (a) the lowest price
offered to any third party independent of 2C and its affiliates that purchase
the PI Chip at comparable volumes or (b) a mutually agreeable price which
provides for the amortization of 2C's NRE costs.

                                      VI.

                                    COVENANTS

         6.1      2C hereby covenants not to utilize 2C Technology, Mobility
Technology or any technology jointly developed by Mobility and 2C in any docking
station product, application, or purpose for portable or handheld computers.

                                      VII.

                              TERM AND TERMINATION

         7.1      The Term of this agreement is perpetual and can only be
terminated upon the written consent of both 2C and Mobility or as provided in
Section 7.2.

         7.2      Either Party shall have the right to terminate this Agreement
upon a material default by the other Party of any of its obligations hereunder,
if such default has not been cured within sixty (60) days after receipt of
written notice from the other Party of the alleged default. For purposes of this
Agreement, a material default includes, but is not limited to, the failure of
Mobility to pay any royalties when due and/ or the use of 2C Technology except
as permitted in this Agreement.

representation by any of the Parties to this Agreement (i) as to the validity,
enforceability or scope of any patent, design patent or utility mode; (ii) that
any manufacture, sale, lease, import, use or other disposition of any products
hereunder will be free from infringement of any intellectual property right of
third parties.

         10.3     Nothing in this Agreement shall be construed as an agreement
or authorization for Mobility to bring or prosecute actions or suits on behalf
of 2C against third parties for patent infringement or conferring any right to
bring or prosecute actions or suits on behalf of 2C against third parties for
patent infringement.

                               GENERAL PROVISIONS

         11.1     MARKINGS. Mobility agrees to identify 2C's products and
packaging incorporating 2C Technology in a manner approved by 2C, which approval
will not be unreasonably withheld.

         11.2     SUPPORT. 2C agrees to provide reasonable support to Mobility
to educate Mobility in the use of 2C Technology at no charge. Additionally, 2C
will provide Mobility with development and architecture systems support to meet
Mobility's new product development objectives and requirements for a charge.
Such charge will be quoted in advance on a case by case basis.

         11.3     ASSIGNMENT; BINDING EFFECT, ETC. This Agreement shall be
binding upon and inure to the benefit of 2C and Mobility and their respective
permitted successors and permitted assigns. Subject to the following, the rights
and licenses of Mobility under this Agreement are personal to Mobility.
Notwithstanding the foregoing, Mobility may assign its rights and licenses under
this Agreement to any Affiliate (as hereinafter defined) or any successor to all
or substantially all of its business or assets without the prior written consent
of 2C, provided such Affiliate or successor assumes in writing the obligations
of Mobility under this Agreement. Mobility Indemnitees and 2C Indemnitees are
intended third party beneficiaries of this Agreement to the extent expressly
provided herein. Any permitted assignment of this Agreement by either party
shall not relieve or release such party from any of its duties or obligations
under this Agreement. 2C shall not assign or transfer the 2C Technology or grant
any security interest, lien, right, license or other encumbrance upon or
respecting the 2C Technology unless such assignment, transfer or grant is made
expressly subject to the licenses and other terms and conditions of this
Agreement. Each and every permitted successor and permitted assign to the
interests of either party to this Agreement shall hold such interests subject to
the terms, conditions and provisions of this Agreement. For the purpose of this
Agreement, the term "Affiliate" shall mean any and all corporations,
partnerships, limited liability entities, and other entities that are in or
under direct or indirect control of Mobility or of another Affiliate of Mobility
and any and all corporations, partnerships, limited liability entities, and
other entities that are under common control with Mobility or any successor to
all or substantially all of the business of Mobility or such Affiliate, and
"control" shall exist whenever there is an ownership, profits, voting, or other
similar interest (including any right or option to obtain such an interest)
representing at least thirty percent (30%) of the total interests of Mobility
then outstanding (treating as outstanding any interests obtainable by Mobility
or the relevant Affiliate pursuant to the exercise of the aforementioned rights
or options).

         11.4     INTERPRETATION. The parties acknowledge and agree that this
Agreement was prepared and drafted by the parties equally, and that neither
party shall be considered to have drafted this Agreement, nor shall this
Agreement, or any term hereof, be construed against a party on the grounds that
the party was the drafter.

         11.5     ARBITRATION. Except as otherwise provided for in this
Agreement, all disputes, claims and controversies between the parties to this
Agreement shall be submitted to arbitration before a panel of three arbitrators.
The arbitration shall be conducted according to the commercial arbitration rules
and the rules governing large, complex cases of the American Arbitration
Association. A party shall commence arbitration under this paragraph by
submitting a concise statement of its claim and a demand for arbitration to the
other party and to the American Arbitration Association. The decision and award
of the arbitrators shall be final and binding, and the award so rendered may be

in Atlanta, Georgia. The arbitrators shall render their decision within thirty
(30) days after the Parties complete their submission of evidence and final
argument.

         11.6     RELIEF. Nothing in this Agreement shall preclude a party from
seeking equitable or injunctive relief from a court on an emergency, temporary
or expedited basis prior to the pendency of an arbitration proceeding; provided
that the arbitration panel, once appointed, shall have the power and authority
to modify or rescind such relief. Venue for any action brought under this
paragraph shall be in Atlanta, Georgia.

accordance with the laws of the State of Delaware, without regard to its choice
of law principles.

         11.8     COUNTERPARTS. This Agreement and any amendments, waivers,
consents or supplements hereto may be executed in any number of counterparts,
and by different parties in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same agreement. Each such agreement

         11.10    ENTIRE AGREEMENT. This Agreement constitutes the full and

<PAGE>   11

and all other communications between the parties relating to such subject
matter. Each party represents and warrants to the other party that in entering
into this Agreement it has not relied on any representations, promises or
assurances from the other party or any employee, officer, director,
representative, or attorney of the other party not expressly contained in this
Agreement. Any other terms or conditions shall not be incorporated herein or be
binding upon either party unless expressly agreed to in writing by both parties.

         11.11    SEVERABILITY. If any provision of this Agreement is declared
or found to be illegal, unenforceable or void, then both parties shall be
relieved of all obligations arising under such provision, but only to the extent
that such provision is illegal, unenforceable or void. Further, this Agreement
shall be deemed amended by modifying such provision to the extent necessary to
make it legal and enforceable while preserving its intent or, if that is not
possible, by substituting therefor another provision that is legal and
enforceable and achieves the same intended objective. If the remainder of this
Agreement shall not be affected by such illegal, unenforceable or void provision
and is capable of substantial performance, then each provision not so affected
shall be enforced to the extent permitted by law.

         11.12    INTERPRETATION. In any interpretation of this Agreement, it
shall be deemed that this Agreement was prepared jointly by the parties, and no
ambiguity shall be construed or resolved against either party on the premise or
presumption that such party was responsible for drafting this Agreement.

         11.13    WAIVER. No delay or omission by either party to exercise any
right or power hereunder shall impair any right or power or be construed to be a
waiver thereof. A waiver by either of the parties of any of the covenants,
conditions or agreements to be performed by the other party or any breach
thereof shall not be construed to be a waiver of any succeeding breach thereof
or of any other covenant, condition or agreement contained herein. All remedies
provided for in this Agreement shall be cumulative and in addition to and not in
lieu of any other remedies available to either party at law, in equity or
otherwise, and may be enforced concurrently therewith or from time to time.

         11.14    HEADINGS. Captions, headings and titles in this Agreement are
for reference purposes only and are neither part of this Agreement nor to be
used for purposes of interpreting the Parties' intent.

         11.15    FURTHER ACTS. Each party shall do, or cause to be done, all
such further acts, and shall execute, acknowledge and deliver, or cause to be
executed, acknowledged and delivered, any and all such further documentation as
the other party reasonably requires to carry out the purposes of this Agreement.

         11.16    MEDIA RELEASES. All media releases, public announcements and
public disclosures by 2C or Mobility, or their respective representatives,
employees or agents, relating to this Agreement or its subject matter or using
the name of the other party shall be coordinated with and approved in writing by
the other party prior to the release thereof. Both 2C and Mobility may publicly
disclose the existence of this Agreement and its broad purpose, but not any of
the specific terms thereof.

         of Shareholders which requested such registration pursuant to Section
         2(a) may request the Company to withdraw or not to file the
         Registration Statement; and

                           (iii) the Company may, at its sole option, elect to
         satisfy a request for a registration pursuant to Section 2(a) on Form
         S-2 or Form S-3 promulgated under the Securities Act (or any successor
         forms thereto), if such forms are then available to the Company.

                  (c) The Company shall file a registration statement with
respect to each registration requested pursuant to Section 2(a) as soon as
practicable after receipt of the demand of the requesting Shareholders;
provided, however, that if in the good faith judgment of the Board of Directors
of the Company, such registration would be seriously detrimental to the Company
in that such registration would interfere with a proposed primary registration
of securities by the Company or any other material corporate transaction and the
Board of Directors concludes, as a result, that it is advisable to defer the
filing of such registration statement at such time (as evidenced by an
appropriate resolution of the Board), then the Company shall have the right to
defer such filing for the period during which such registration would be
seriously detrimental; provided, further, however, that (i) the Company may not
defer the filing for a period of more than one hundred and twenty (120) days
after receipt of the demand of the requesting Shareholders, (ii) the Company
shall not exercise its right to defer such a registration more than once, and
(iii) if the Company undertakes a primary registration following an exercise of
its deferral right, the holders of Registrable Shares shall have "piggyback"
rights under Section 3 hereof with respect to not less than one-third (1/3) of
the number of shares of Registrable Shares to be sold in such offering.

         Section 3.  Piggyback Registration.

                  If the Company at any time that is 180 days after its initial
Public Offering proposes for any reason to register shares of Common Stock under
the Securities Act (other than on Form S-4 or Form S-8 promulgated under the
Securities Act or any successor forms thereto), it shall promptly give written
notice to the Shareholders of its intention to so register such shares and, upon
the written request, delivered to the Company within 20 days after delivery of
any such notice by the Company, of any Shareholder to include in such
registration Registrable Shares (which request shall specify the number of
Registrable Shares proposed to be included in such registration), the Company
shall use its best efforts to cause all such Registrable Shares to be included
in such registration on the same terms and conditions as the Common Stock
otherwise being sold in such registration; provided, however, that if the
managing underwriter advises the Company that the inclusion of all Registrable
Shares requested to be included in such registration would interfere with the
successful marketing (including pricing) of the Primary Shares or Other Shares
proposed to be registered by the Company, then the number of Primary Shares,
Registrable Shares and Other Shares proposed to be included in such registration
shall be included in the following order:

                                      -5-
<PAGE>   8

                           (i) first, the Primary Shares or other Shares
         proposed to be registered by the Company; and

                           (ii) second, the Registrable Shares requested to be
         included in such registration pursuant to this Section 3, pro rata
         among the holders thereof based upon the number of Registrable Shares
         requested to be registered by each such holder; and

                           (iii) any other Shares.

         Section 4.  Registrations on Form S-3.

                  (a) Anything contained in Section 2 to the contrary
notwithstanding, at such time as the Company shall have qualified for the use of
Form S-3 promulgated under the Securities Act or any successor form thereto, a
Majority of Shareholders shall have the right to request in writing an unlimited
number of registrations of Registrable Shares on Form S-3 or such successor
form, which request or requests shall (i) specify the number of Registrable
Shares intended to be sold or disposed of and the holders thereof, (ii) state
the intended method of disposition of such Registrable Shares and (iii) relate
to Registrable Shares having an anticipated aggregate gross offering price
(before underwriting discounts and commissions) of at least $10,000,000, and
upon receipt of any such request, the Company shall use its best efforts
promptly to effect the registration under the Securities Act of the Registrable
Shares so requested to be registered. A requested registration on Form S-3 or
any such successor form in compliance with this Section 4 shall be treated as a
registration initiated pursuant to, and shall be subject to, the provisions of
Section 2.

                  (b) Subject to the further provisions of this Section 4(b), if
at any time after the first anniversary of this Agreement the Strategic Investor
requests that the Company include Registrable Shares for sale to the public
pursuant to a registration statement filed under the Securities Act on Form S-3
(including any successor form thereto), the Company shall use its best efforts
to promptly effect the registration under the Securities Act of such Registrable
Shares. Notwithstanding the foregoing provisions of this Section 4(b), the
Company shall not be obligated to effect any such registration pursuant to this
Section 4(b):

                           (i) if Form S-3 (or any successor or similar form)
         is not available for such offering; or

                           (ii) if the Strategic Investor proposes to sell
         Registrable Shares with an anticipated aggregate gross offering price
         (before underwriting discounts and commissions) to the public of less
         than five million dollars ($5,000,000); provided, however, that if the
         Strategic Investor has not previously requested a registration pursuant
         to this Section 4(b) and the anticipated aggregate gross offering price
         (before underwriting discounts and commissions) to the public of all
         Registrable Shares then held by the Strategic Investor is less than
         five million dollars ($5,000,000), then the Strategic Investor may
         request that the Company register all (but not less than all) of its
         Registrable Shares pursuant to this Section 4(b); or

                                      -6-
<PAGE>   9

                           (iii) if the Strategic Investor receives the written
         offer from the Company contemplated pursuant to Section 2(a), Section 3
         or Section 4(a) hereof to include Registrable Shares in a registration
         contemplated pursuant to Section 2(a), Section 3 or Section 4(a) hereof
         within ten days after making its request for registration pursuant to
         this Section 4(b); or

                           (iv) if the Company shall furnish to the Strategic
         Investor a certificate signed by the Chairman of the Board of Directors
         of the Company stating that in the good faith judgment of the Board of
         Directors of the Company, it would be seriously detrimental to the
         Company and its stockholders for such registration to be effected at
         such time, in which event the Company shall have the right to defer the
         filing of such registration statement for a period of not more than one
         hundred and twenty (120) days after receipt of the request of the
         Strategic Investor under this Section 4(b); provided, that such right
         to delay a request shall be exercised by the Company not more than once
         in any twelve (12) month period; or

                           (v) if the Company has, within the twelve (12) month
         period preceding the date of such request, already effected one (1)
         registration pursuant to a request made pursuant to this Section 4(b).

         Section 5.  Holdback Agreement.

                  (a) If the Company at any time shall register shares of Common
Stock under the Securities Act (including any registration pursuant to Section
2, Section 3 or Section 4) for sale to the public pursuant to an underwritten
offering, the Shareholders shall not sell publicly, make any short sale of,
grant any option for the purchase of, or otherwise dispose publicly of, any
Registrable Shares (other than those shares of Common Stock included in such
registration pursuant to Sections 2, 3 or 4) without the prior written consent
of the Company, for a period designated by the Company in writing to the
Shareholders, which period shall not begin more than 10 days prior to the
effectiveness of the Registration Statement pursuant to which such public
offering shall be made and shall not last more than 180 days after the closing
of sale of shares pursuant to such Registration Statement. The Company shall use
reasonable efforts to obtain the agreement of any Person permitted to sell
shares of Common Stock in a registration to be bound by and to comply with this
Section 5 with respect to such registration as if such Person was a Shareholder
hereunder.

                  (b) If the Company at any time pursuant to Section 2 or
Section 3 of this Agreement shall register under the Securities Act Registrable
Shares held by Shareholders for sale to the public pursuant to an underwritten
offering the Company shall not effect any public sale or distribution of
securities similar to those being registered, or any securities convertible into
or exercisable or exchangeable for such securities, for such period as shall be
determined by the managing underwriters, which period shall not begin more than
10 days prior to the effectiveness of the Registration Statement pursuant to
which such public offering shall be made and shall not last more than 180 days
after the closing of sale of shares pursuant to such Registration Statement.

         Section 6.  Preparation and Filing.

                  (a) If and whenever the Company is under an obligation
pursuant to the provisions of this Agreement to use its best efforts to effect
the registration of, and keep effective a Registration Statement for, any
Registrable Shares, the Company shall, as expeditiously as practicable:

                           (i) use its best efforts to cause a Registration
         Statement that registers such Registrable Shares to become and remain
         effective for a period of 90 days (extended for such period of time as
         the Shareholders are required to discontinue disposition of Registrable
         Shares pursuant to Section 6(b) below) or until all of such Registrable
         Shares have been disposed of (if earlier);

                           (ii) use its best efforts to furnish, at least five
         business days before filing a Registration Statement that relates to
         the registration of such Registrable Shares, a Prospectus relating
         thereto or any amendments or supplements relating to such a
         Registration Statement or Prospectus, to one counsel (the
         "Shareholders' Counsel") selected by a Majority of Shareholders, copies
         of all such documents proposed to be filed;

                           (iii) [Intentionally omitted];

                           (iv) notify in writing the Shareholders' Counsel, and
         the Shareholders whose Registrable Shares may be included in such
         Registration Statement, promptly of (A) the receipt by the Company of
         any notification with respect to any comments by the Commission with
         respect to such Registration Statement or Prospectus or any amendment
         or supplement thereto or any request by the Commission for the amending
         or supplementing thereof or for additional information with respect
         thereto, (B) the receipt by the Company of any notification or written
         information with respect to the issuance or threatened issuance by the
         Commission of any stop order suspending the effectiveness of such
         Registration Statement or Prospectus or any amendment or supplement
         thereto or the initiation or threatening of any proceeding for that
         purpose (and the Company shall use its best efforts to prevent the
         issuance thereof or, if issued, to obtain its withdrawal) and (C) the
         receipt by the Company of any notification with respect to the
         suspension of the qualification of such Registrable Shares for sale in
         any jurisdiction or the initiation or threatening of any proceeding for
         such purposes;

                           (v) use its best efforts to register or qualify such
         Registrable Shares under such other securities or blue sky laws of such
         jurisdictions as the Shareholders holding such Registrable Shares
         reasonably request and do any and all other acts and things which may
         be reasonably necessary or advisable to enable the Shareholders to
         consummate the disposition in such jurisdictions of the Registrable
         Shares owned by the Shareholders; provided, however, that the Company
         will not be required to qualify generally to do business, subject
         itself to general taxation or consent to general service of process in
         any jurisdiction where it would not otherwise be required to do so but
         for this clause (v);

                                      -8-
<PAGE>   11

                           (vi) furnish to the Shareholders holding such
         Registrable Shares such number of copies of a summary Prospectus, if
         any, or other Prospectus, including a preliminary Prospectus, in
         conformity with the requirements of the Securities Act, and such other
         documents as such Shareholders may reasonably request in order to
         facilitate the public sale or other disposition of such Registrable
         Shares;

                           (vii) use its best efforts to cause such Registrable
         Shares to be registered with or approved by such other governmental
         agencies or authorities as may be necessary by virtue of the business
         and operations of the Company to enable the Shareholders holding such
         Registrable Shares to consummate the disposition of such Registrable
         Shares;

                           (viii) notify the Shareholders holding such
         Registrable Shares on a timely basis at any time when a Prospectus
         relating to such Registrable Shares is required to be delivered under
         the Securities Act within the appropriate period mentioned in clause
         (i) of this Section 6(a), of the happening of any event as a result of
         which the Prospectus included in such Registration Statement, as then
         in effect, includes an untrue statement of a material fact or omits to
         state a material fact required to be stated therein or necessary to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading, and prepare and furnish to such
         Shareholders a reasonable number of copies of, and file with the
         Commission, a supplement to or an amendment of such Prospectus as may
         be necessary so that, as thereafter delivered to the offerees of such
         shares, such Prospectus shall not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading;

                           (ix) subject to the execution of confidentiality
         agreements in form and substance reasonably satisfactory to the
         Company, make available upon reasonable notice and during normal
         business hours, for inspection by the Shareholders holding Registrable
         Shares requested to be included in such registration, any underwriter
         participating in any disposition pursuant to such Registration
         Statement and any attorney, accountant or other agent retained by the
         Shareholders or underwriter (collectively, the "Inspectors"), all
         pertinent financial and other records, pertinent corporate documents
         and properties of the Company (collectively, the "Records"), and cause
         the Company's officers, directors and employees to supply all
         information (together with the Records, the "Information") reasonably
         requested by any such Inspector, in each case as shall be reasonably
         necessary to enable them to exercise their due diligence responsibility
         in connection with such Registration Statement; provided, however, that
         any of the Information that the Company determines in good faith to be
         confidential, and of which determination the Inspectors are so
         notified, shall not be disclosed by the Inspectors unless (A) the
         disclosure of such Information is necessary to avoid or correct a
         misstatement or omission in the Registration Statement or Prospectus,
         (B) the release of such Information is ordered pursuant to a subpoena
         or other order from a court of competent jurisdiction or, upon the
         written advice of counsel, is otherwise required by law, or (C) such
         Information has been made generally available to the public, and the
         Shareholders agree that they will, upon learning that disclosure of
         such Information is sought in a court of competent jurisdiction,

                                      -9-
<PAGE>   12

         give notice to the Company and allow the Company, at the Company's
         expense, to undertake appropriate action to prevent disclosure of the
         Information deemed confidential;

                           (x) use its best efforts to obtain from its
         independent certified public accountants "cold comfort" letters in
         customary form and at customary times and covering matters of the type
         customarily covered by cold comfort letters;

                           (xi) use its best efforts to obtain from its counsel
         an opinion or opinions in customary form naming the Shareholders as
         additional addressees or parties who may rely thereon;

                           (xii) provide a transfer agent and registrar (which
         may be the same entity and which may be the Company) for such
         Registrable Shares;

                           (xiii) issue to any underwriter to which the
         Shareholders holding such Registrable Shares may sell shares in such
         offering certificates evidencing such Registrable Shares;

                           (xiv) list such Registrable Shares on any national
         securities exchange on which any shares of the Common Stock are listed
         or, if the Common Stock is not listed on a national securities
         exchange, use its best efforts to qualify such Registrable Shares for
         inclusion on the Nasdaq National Market;

                           (xv) otherwise use its best efforts to comply with
         all applicable rules and regulations of the Commission and make
         available to its security holders, as soon as reasonably practicable,
         earnings statements (which need not be audited) covering a period of
         12 months beginning within three months after the effective date of the
         Registration Statement, which earnings statements shall satisfy the
         provisions of Section 1l(a) of the Securities Act; and

                           (xvi) use its best efforts to take all other steps
         necessary to effect the registration of, and maintain an effective
         Registration Statement with respect to, such Registrable Shares
         contemplated hereby.

                  (b) Each holder of the Registrable Shares, upon receipt of any
notice from the Company of any event of the kind described in Section 6(a)(viii)
hereof, shall forthwith discontinue disposition of the Registrable Shares
pursuant to the Registration Statement coveting such Registrable Shares until
such holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 6(a)(viii) hereof, and, if so directed by the Company,
such holder shall deliver to the Company all copies, other than permanent file
copies then in such holders possession, of the most recent Prospectus covering
such Registrable Shares at the time of receipt of such notice.

         Section 7.  Expenses.

                  All expenses (other than underwriting discounts and
commissions relating to the Registrable Shares) incurred by the Company and the
Shareholders in complying with this Agreement, including, without limitation,
all registration and filing fees (including all expenses incident to filings
with the National Association of Securities Dealers, Inc.), fees and expenses of
complying with securities and blue sky laws, printing expenses, fees and
expenses of the Company's counsel and accountants and fees and expenses of the
Shareholders' Counsel, shall be paid by the Company in connection with
registrations requested under Section 2 or Section 4; provided, however, that
all underwriting discounts and selling commissions applicable to the Registrable
Shares and Other Shares shall be borne by the holders selling such Registrable
Shares and Other Shares, in proportion to the number of Registrable Shares and
Other Shares sold by each such holder.

         Section 8.  Indemnification.

                  (a) In connection with any registration of any Registrable
Shares under the Securities Act pursuant to this Agreement, the Company shall
indemnify and hold harmless, to the fullest extent permitted by law, each holder
of Registrable Shares, each underwriter, broker or any other Person acting on
behalf of the holders of Registrable Shares and each other Person, if any, who
controls any of the foregoing Persons within the meaning of the Securities Act
(each such indemnified Person being referred to herein as an "Indemnified
Person") against any losses, claims, damages or liabilities, joint or several
(or actions in respect thereof), to which any of the foregoing Persons may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or allegedly untrue statement of a material
fact contained in or incorporated by reference in the Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary Prospectus or final Prospectus contained therein or otherwise
filed with the Commission, any amendment or supplement thereto or any document
incident to registration or qualification of any Registrable Shares, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or, with respect to any Prospectus, necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or any violation by the Company of the Securities Act or state
securities or blue sky laws applicable to the Company and relating to action or
inaction required of the Company in connection with such registration or
qualification under such state securities or blue sky laws; and shall promptly
reimburse the Indemnified Persons for any legal or other expenses reasonably
incurred by any of them in connection with investigating or defending any such
loss, claim, damage, liability or action; provided, however, that the Company
shall not be liable in any such case to any such Indemnified Person to the
extent that any such loss, claim, damage, liability or action (including any
legal or other expenses incurred) arises out of or is based upon: (i) an untrue
statement or allegedly untrue statement or omission or alleged omission made in
said Registration Statement, preliminary Prospectus, final Prospectus,
amendment, supplement or document incident to registration or qualification of
any Registrable Shares in reliance upon and in conformity with written
information furnished to the Company through an instrument duly executed by such
Indemnified Person specifically for use in the preparation thereof or (ii) any

                                      -11-
<PAGE>   14

Indemnified Person's failure to deliver a copy of the Prospectus (including any
amendment or supplement thereto) after the Company has delivered to such
Indemnified Person a sufficient number of copies of the same.

                  (b) In connection with any registration of Registrable Shares
under the Securities Act pursuant to this Agreement, each holder of Registrable
Shares being registered shall, severally and not jointly, to the fullest extent
permitted by law, indemnify and hold harmless (in the same manner and to the
same extent as set forth in Section 8(a) above) the Company, each director of
the Company, each officer of the Company who shall have signed such Registration
Statement, each other holder of Registrable Shares or Other Shares, each agent,
underwriter, broker or other Person acting on behalf of the Company, each other
holder of Registrable Shares or Other Shares and each Person who controls any of
the foregoing Persons within the meaning of the Securities Act with respect to
any statement or omission from such Registration Statement, any preliminary
Prospectus or final Prospectus contained therein or otherwise filed with the
Commission, any amendment or supplement thereto or any document incident to
registration or qualification of any Registrable Shares, if such statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company or such underwriter through an instrument duly executed
by such holder specifically for use in connection with the preparation of such
Registration Statement, preliminary Prospectus, final Prospectus, amendment,
supplement or document; provided, however, that the maximum amount of liability
in respect of such indemnification shall be limited, in the case of each seller
of Registrable Shares, to an amount equal to the net proceeds actually received
by such seller from the sale of Registrable Shares effected pursuant to such
registration.

                  (c) Promptly after receipt by an indemnified party of notice
of the commencement of any action involving a claim referred to in Section 8(a)
or Section 8(b), such indemnified party will, if a claim in respect thereof is
made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the indemnified party's
failure to give such notice shall not release, relieve or in any way affect the
indemnifying party's obligation hereunder to indemnify the indemnified party
unless and to the extent that the rights of the indemnifying party are
prejudiced thereby. In case any such action is brought against an indemnified
party, the indemnifying party will be entitled to participate in and to assume
the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that he, she, or it may wish, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of his, her or its election so to assume the
defense thereof, the indemnifying party shall not be responsible for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof, provided, however, that if any indemnified party shall
have reasonably concluded (based on the written advice of counsel) that there
may be one or more legal or equitable defenses available to such indemnified
party which are additional to or conflict with those available to the
indemnifying party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this
Section 8, the indemnifying party shall not have the right to assume the defense
of such action on behalf of such indemnified party and such indemnifying party
shall reimburse such indemnified party and any Person controlling such
indemnified party for that portion of the fees and expenses of any counsel
retained by the

                                      -12-

indemnified party which is reasonably related to the matters covered by the
indemnity agreement provided in this Section 8.

                  (d) If the indemnification provided for in this Section 8 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, claim, damage, liability or action referred to
herein (other than as a result of the applicability of the proviso in Section
8(a)), then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amounts paid or payable by such
indemnified party as a result of such loss, claim, damage, liability or action
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions which resulted in such loss, claim,
damage, liability or action as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

         Section 9.  Underwriting Agreement.

                  (a) If any registration pursuant to Section 2 or Section 4 is
requested to be an underwritten offering, the Company shall negotiate in good
faith to enter into a reasonable and customary underwriting agreement with the
underwriters thereof. The Company shall be entitled to receive indemnities from
lead institutions, underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the same
extent as provided above with respect to information so furnished in writing by
such Persons specifically for inclusion in any Prospectus or Registration
Statement and to the extent customary given their role in such distribution.

                  (b) No Shareholder may participate in any registration
hereunder that is underwritten unless such Shareholder agrees to (i) sell such
Shareholder's Registrable Shares proposed to be included therein on the basis
provided in any underwriting arrangements approved by the Company and a majority
of the Registrable Shares being included in such registration and (ii) as
expeditiously as possible, notify the Company of the occurrence of any event
concerning such Shareholder as a result of which the Prospectus relating to such
registration contains an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

         Section 10.  Information by Holder.

                  The Shareholders shall furnish to the Company such written
information regarding the Shareholders and the distribution proposed by the
Shareholders as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Agreement.

         Section 11.  Exchange Act Compliance.

                  From the Registration Date or such earlier date as a
Registration Statement filed by the Company pursuant to the Exchange Act
relating to any class of the Company's securities shall have become effective,
the Company shall comply with all of the reporting requirements of the Exchange
Act applicable to it (whether or not it shall be required to do so) and shall
comply with all other public information reporting requirements of the
Commission which are conditions to the availability of Rule 144 for the sale of
the Common Stock. The Company shall cooperate with the Shareholders in supplying
such information as may be necessary for the Shareholders to complete and file
any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

         Section 12.  Mergers, Etc.

                  The Company shall not, directly or indirectly, enter into any
merger, consolidation or reorganization in which the Company shall not be the
surviving corporation unless the surviving corporation shall, prior to such
merger, consolidation or reorganization, agree in writing to assume the
obligations of the Company under this Agreement, and for that purpose references
hereunder to "Registrable Shares" shall be deemed to include the shares of
common stock, if any, or other securities that the Shareholders would be
entitled to receive in exchange for Common Stock under any such merger,
consolidation or reorganization; provided, however, that, to the extent the
Shareholders receive securities that are by their terms convertible into shares
of common stock of the issuer thereof, then any such shares of common stock as
are issued or issuable upon conversion of said convertible securities shall be
included within the definition of "Registrable Shares."

         Section 13.  New Certificates.

                  As expeditiously as possible after the effectiveness of any
Registration Statement filed pursuant to this Agreement, the Company will
deliver in exchange for any legended certificate evidencing Registrable Shares
so registered, new stock certificates not bearing any restrictive legends.

         Section 14.  No Conflict of Rights; Selection of Underwriter.

                  The Company shall not, at any time after the date hereof,
grant any registration rights that conflict with or impair, or have any parity
with or priority over, the registration rights granted hereby. In any Public
Offering, the managing underwriter shall be a nationally recognized investment
banking firm chosen by the Board.

         Section 15.  Termination.

                  This Agreement shall terminate and be of no further force or
effect upon the written agreement of the Company, a majority of Registrable
Shares held by the Investors (which majority must include the affirmative vote
of all Registrable Shares then held by UBS) and a majority of Registrable Shares
held by all other Shareholders (which majority must include the

                                      -14-
<PAGE>   17

affirmative vote of all Registrable Shares then held by the Strategic Investor)
or when there shall no longer be any Restricted Shares outstanding.

         Section 16.  Miscellaneous.

                  (a) Successors and Assigns. Except as expressly set forth
herein, this Agreement shall bind and inure to the benefit of the Company and
the Shareholders and, subject to Section 16(b), the respective successors and
assigns of the Company and the Shareholders. This Agreement is not intended to
create any third party beneficiaries.

                  (b) Assignment. Each Shareholder may assign its rights
hereunder to any purchaser or transferee of Registrable Shares; provided,
however, that such purchaser or transferee shall, as a condition to the
effectiveness of such assignment, unless already a party to this Agreement, be
required to execute a counterpart to this Agreement agreeing to be treated as
Shareholder hereunder, whereupon such purchaser or transferee shall have the
benefits of and shall be subject to the restrictions contained in this Agreement
as if such purchaser or transferee was originally included in the definition of
a Shareholder and had originally been a party hereto.

                  (c) Severability. It is the desire and intent of the parties
hereto that the provisions of this Agreement be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any particular provision of this
Agreement shall be adjudicated by a court of competent jurisdiction to be
invalid, prohibited or unenforceable for any reason, such provision, as to such
jurisdiction, shall be ineffective, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of this
Agreement or affecting the validity or enforceability of such provision in any
other jurisdiction. Notwithstanding the foregoing, if such provision could be
more narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.

                  (d) Entire Agreement. This Agreement and the other writings
referred to herein or delivered pursuant hereto contain the entire agreement
among the parties with respect to the subject matter hereof and thereof and
supersede all prior and contemporaneous arrangements or understandings with
respect hereto and thereto (including, without limitation, the Existing
Agreement).

                  (e) Notices. All communications hereunder to any party shall
be deemed to be sufficient if contained in a written instrument delivered in

JURISDICTION OTHER THAN THE STATE OF DELAWARE TO BE APPLIED. IN FURTHERANCE OF

JURISDICTION'S CHOICE OF LAW OR CONFLICT OF LAW ANALYSIS, THE SUBSTANTIVE LAW OF
SOME OTHER JURISDICTION WOULD ORDINARILY APPLY.

not be deemed to modify, limit or restrict in any manner the construction of the
general statement to which it relates. The language used in this Agreement shall

intent, and no rule of strict construction shall be applied against any party.

                  (m) Effectiveness. This Agreement shall not be deemed
effective (and the Existing Agreement shall remain in full force and effect)

a majority of all Registrable Shares held by the Investors (which majority must
include the affirmative vote of all Registrable Shares then held by UBS) and a
majority of all Registrable Shares held by the Continuing Shareholders.
