<PAGE>   4
("Short-Form Registrations"), if available. In addition, subject to Section 2(g)
below, the holders of a majority of the Cornerstone Registrable Securities or
the PPEI Registrable Securities, as the case may be, may request that the
Company, with respect to any Registrable Securities held by such holders file
with the SEC a registration statement under the Securities Act on any applicable
form pursuant to Rule 415 under the Securities Act (a "415 Registration"). Each
request for a Long-Form Registration or Short-Form Registration shall specify
the approximate number of Registrable Securities requested to be registered and
the anticipated per share price range for such offering. Within ten days after
receipt of any such request for a Long-Form Registration or Short-Form
Registration, (1) the Company will give written notice of such requested
registration to all other holders of Registrable Securities and will include
(subject to the provisions of this Agreement) in such registration, all
Registrable Securities with respect to which the Company has received written
requests for inclusion therein within 20 days after the receipt of the Company's
notice. All registrations requested pursuant to this Section 2(a) are referred
to herein as "Demand Registrations".

                  (b) Long-Form Registrations. The holders of the Cornerstone
Registrable Securities and the holders of the PPEI Registrable Securities will
each be entitled to request up to five (5) Long-Form Registrations with respect
to Registrable Securities held by such holders, in which the Company will pay
all Registration Expenses. The holders of the Kuck Registrable Securities will
be entitled to request up to three (3) Long-Form Registrations with respect to
Registrable Securities held by such holders, in which the Company will pay all
Registration Expenses. The holders of the Series C Registrable Securities will
be entitled to request one (1) Long-Form Registration with respect to
Registrable Securities held by such holders, in which the Company will pay all
Registration Expenses. The holders of the Wisconsin Registrable Securities will
be entitled to request one (1) Long-Form Registration with respect to
Registrable Securities held by such holders, in which the Company will pay all
Registration Expenses. A registration will not count as a permitted Long-Form
Registration until it has become effective and unless the holders of Cornerstone
Registrable Securities, PPEI Registrable Securities, Kuck Registrable
Securities, Series C Registrable Securities, or Wisconsin Registrable
Securities, as the case may be, are able to register and sell at least 80% of
the Registrable Securities that holders of Cornerstone Registrable Securities,
PPEI Registrable Securities, Kuck Registrable Securities, Series C Registrable
Securities, or Wisconsin Registrable Securities, as the case may be, have
requested to be included in such registration.

                  (c) Short-Form Registrations. In addition to the Long-Form
Registrations provided pursuant to Section 2(b), holders of Registrable
Securities will be entitled to request an unlimited number of Short-Form
Registrations with respect to Registrable Securities held by such holders in
which the Company will pay all Registration Expenses. Demand Registrations
(other than 415 Registrations) will be Short-Form Registrations whenever the
Company is permitted to use any applicable short form. After the Company has
become subject to the reporting requirements of the Exchange Act, the Company
will use its best efforts to make Short-Form Registrations available for the
sale of Registrable Securities, and after the Company has become subject to such
reporting requirements, the Company will use its best efforts to make Short-Form
Registrations available for the sale of Registrable Securities.

                  (d) Priority on Demand Registrations. The Company will not
include in any Long-Form Registration or Short-Form Registration any securities
which are not Registrable Securities without the prior written consent of the
holders of at least a majority of the Cornerstone Registrable Securities, PPEI
Registrable Securities, Kuck Registrable Securities, Series C Registrable
Securities, or Wisconsin Registrable Securities, as the case may be, demanding
such registration. If a Long-Form Registration or a Short-Form Registration is
an underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering,
exceeds the number of Registrable Securities and other securities, if any, which
can be sold therein without adversely affecting the marketability of the
offering (including price), the Company will include in such registration (i)
first, the number of Registrable Securities requested to be included in such
registration pro rata, if necessary, among the holders of Registrable Securities
based on the number of shares of Registrable Securities held by each such holder
and (ii) second, any other securities of the Company requested to be included in
such registration pro rata, if necessary, on the basis of the number of shares
of such other securities owned by each such holder. Any Persons other than
holders of Registrable Securities who participate in Demand Registrations which
are not at the Company's expense, must pay their share of the Registration
Expenses as provided in Section 6 hereof.

                  (e) Restrictions on Demand Registrations. The Company will not
be obligated to effect any Demand Registration within three months after the
effective date of a previous Demand Registration for Registrable Securities.

                  (f) Selection of Underwriters. In the case of a Demand
Registration for an underwritten offering, the holders of a majority of the
Registrable Securities to be included in such Demand Registration will have the
right to select the investment banker(s) and manager(s) to administer the
offering, which investment banker(s) and manager(s) will be nationally
recognized.

                  (g) 415 Registrations.

                      (i) The holders of a majority of the Cornerstone
Registrable Securities and the holders of a majority of the PPEI Registrable
Securities will each be entitled to request one (1) 415 Registration with
respect to Cornerstone Registrable Securities and PPEI Registrable Securities,
respectively, in which the Company will pay all Registration Expenses; provided,
that Kuck and the holders of the Series C Registrable Securities have the right
to participate in any such registration pro rata with Cornerstone and PPEI on
the basis of the number of shares of Registrable Securities held by such
holders. Subject to the availability of required financial information, within
45 days after the Company receives written notice of a request for a 415
Registration, the Company shall file with the SEC a registration statement under
the Securities Act for the 415 Registration. The Company shall use its best
efforts to cause the 415 Registration to be declared effective under the
Securities Act as soon as practical after filing, and once effective, the
Company shall (subject to the provisions of clause (ii) below) cause such 415
Registration to remain effective for such time period as is specified in such
request, but for no time period longer than the period ending on the earlier of
(1) the third anniversary of the date of filing of such 415 Registration, (2)
the date on which all Registrable Securities so registered have been sold
pursuant to the 415 Registration or

                                       -5-
<PAGE>   6
(3) the date as of which there are no longer any Registrable Securities in
existence. Any sale pursuant to the registration contemplated by this subsection
3(g)(i) is referred to herein as a "Takedown."

                      (ii) If the holders of a majority of the Cornerstone
Registrable Securities, the holders of a majority of the PPEI Registrable
Securities, the holders of a majority of the Kuck Registrable Securities, or the
holders of a majority of the Series C Registrable Securities notify the Company
in writing that they intend to effect the sale of all or a substantial portion
of the Cornerstone Registrable Securities, the Kuck Registrable Securities, the
PPEI Registrable Securities, or the Series C Registrable Securities held by such
holders, pursuant to a Takedown, the Company and each holder of Registrable
Securities shall not effect any public sale or distribution of its equity
securities, or any securities convertible into or exchangeable or exercisable
for its equity securities, during the 90-day period beginning on the date such
notice of a Takedown is received.

                      (iii) If in connection with any Takedown the managing
underwriters (selected in accordance with clause (iv) below) advise the Company
that, in their opinion, the inclusion of any securities other than Cornerstone
Registrable Securities, Kuck Registrable Securities, PPEI Registrable
Securities, or Series C Registrable Securities would adversely affect the
marketability of the offering, then no such other securities shall be permitted
to be included. Additionally, if in connection with such an offering, the number
of Cornerstone Registrable Securities, Kuck Registrable Securities, PPEI
Registrable Securities, Series C Registrable Securities and other securities (if
any) requested to be included in such Takedown exceeds the number of Cornerstone
Registrable Securities, PPEI Registrable Securities, Kuck Registrable
Securities, Series C Registrable Securities and other securities which can be
sold in such offering without adversely affecting the marketability of the
offering, the Company shall include in such Takedown (i) first, the Cornerstone
Registrable Securities, Kuck Registrable Securities, PPEI Registrable Securities
and Series C Registrable Securities requested to be included in such Takedown,
pro rata among the holders of such Cornerstone Registrable Securities, Kuck
Registrable Securities, PPEI Registrable Securities and Series C Registrable
Securities on the basis of the number of Cornerstone Registrable Securities,
Kuck Registrable Securities, PPEI Registrable Securities and Series C
Registrable Securities owned by each such holder, (ii) second, the remaining
Registrable Securities requested to be included in such Takedown, pro rata among
the holders of such Registrable Securities on the basis of the number of
Registrable Securities owned by each such holder, and (iii) third, other
securities requested to be included in such Takedown to the extent permitted
hereunder.

                      (iv) The holders of a majority of the Cornerstone
Registrable Securities and the holders of a majority of the PPEI Registrable
Securities shall have the right to retain and select an investment banker and
manager to administer the 415 Registration with respect to Registrable
Securities and any Takedown pursuant thereto.

                      (v) In addition to the provisions in Section 6 below, all
expenses incurred in connection with the management of the 415 Registration
(whether incurred by the Company, the holders of the Cornerstone Registrable
Securities, or the holders of the PPEI Registrable Securities)

                                       -6-
<PAGE>   7
shall be borne by the Company (including, without limitation, all fees and
expenses of the investment banker and manager) (excluding discounts and
commissions).

                  (h) Other Registration Rights. Except as provided in this
Agreement, the Company shall not grant to any Persons the right to request the
Company to register any of its equity securities or any securities convertible
or exchangeable into or exercisable for such securities, without the prior
written consent of the holders of a majority of the Cornerstone Registrable
Securities and the holders of a majority of the PPEI Registrable Securities.

                  3.  Piggyback Registrations.

                  (a) Right to Piggyback. Whenever the Company proposes to
register any shares of Common Stock under the Securities Act (in the case of all
holders of Registrable Securities except holders of Sigma Registrable
Securities, other than pursuant to a Demand Registration, and in the case of all
holders of Registrable Securities, other than pursuant to a registration
statement on Form S-8 or S-4 or any similar form or in connection with a
registration the primary purpose of which is to register debt securities (i.e.,
in connection with a so-called "equity kicker")), and a registration form to be
used may be used for the registration of Registrable Securities (a "Piggyback
Registration"), the Company will give prompt written notice to all holders of
Registrable Securities of its intention to effect such a registration. The
Company shall include in any such registration by it all Registrable Securities
with respect to which it has received written requests for inclusion therein
within 20 days after the receipt of the Company's notice. Notwithstanding the
foregoing, in connection only with the initial registered public offering of the
Company's securities which offering is a primary offering, no Registrable
Securities shall be included in such registration without the prior written
consent of the Company; provided, that if the Company consents to include in
such registration any Registrable Securities held by any holder of Registrable
Securities, the Company shall consent to include in such registration the
Registrable Securities of all holders of Registrable Securities in accordance
with the provisions of Section 3(c) below.

                  (b) Piggyback Expenses. The Registration Expenses of the
holders of Registrable Securities will be paid by the Company.

                  (c) Priority on Primary Registrations. Subject to paragraph
3(a), if a Piggyback Registration is an underwritten primary registration on
behalf of the Company, the Company will include in such registration all
Registrable Securities requested to be included in such registration; provided,
that if the managing underwriters advise the Company in writing that in their
opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering without adversely
affecting the marketability of the offering, the Company will include in such
registration (i) first, the securities that the Company proposes to sell, (ii)
second, the number of Registrable Securities requested to be included in such
registration, pro rata among the holders of such Registrable Securities on the
basis of the number of shares of Registrable Securities owned by each such
holder, and (iii) third, other securities, if any, requested to be included in
such registration not covered by clause (i) above.

                                       -7-
<PAGE>   8
                  (d) Priority on Secondary Registrations. If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Company's securities (which registration was consented to pursuant to
Section 2(h) above), and the managing underwriters advise the Company in writing
that in their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering without
adversely affecting the marketability of the offering, the Company will include
in such registration (i) first, the securities requested to be included therein
by the holders requesting such registration, (ii) second, the number of
Registrable Securities requested to be included in such registration, pro rata
among the holders of such Registrable Securities on the basis of the number of
shares of Registrable Securities owned by each such holder, and (iii) third,
other securities, if any, requested to be included in such registration not
covered by clause (i) above.

                  (e) Selection of Underwriters. If any Piggyback Registration
is an underwritten offering, the investment banker(s) and manager(s) for the
offering shall be acceptable to the holders of a majority of the Registrable
Securities for which registration has been proposed.

                  (f) Other Registrations. If (i) the Company has previously
filed a registration statement with respect to Registrable Securities pursuant
to this Section 3, and if such previous registration has not been withdrawn or
abandoned, the Company will not file or cause to be effected any other
registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Securities
Act (except on Forms S-4 or S-8 or any successor forms), whether on its own
behalf or at the request of any holder or holders of such securities, until a
period of at least six months has elapsed from the effective date of such
previous registration.

                  4.  Holdback Agreements.

                  (a) Each holder of Registrable Securities hereby agrees not to
effect any public sale or distribution (including sales pursuant to Rule 144) of
equity securities of the Company or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and the 180-day period beginning on the effective date of any Demand
Registration (other than a 415 Registration) or Piggyback Registration for a
public offering to be underwritten on a firm commitment basis in which
Registrable Securities are included (except as part of such underwritten
registration), unless the underwriters managing the registered public offering
otherwise agree.

                  (b) The Company agrees (i) not to effect any public sale or
distribution of its respective equity securities, or any securities convertible
into or exchangeable or exercisable for such securities, during the seven days
prior to and during the 180-day period beginning on the effective date of any
underwritten Demand Registration (other than a 415 Registration) or Piggyback
Registration for Registrable Securities (except as part of such underwritten
registration or pursuant to registrations on Forms S-4 or S-8 or any successor
forms), unless the underwriters managing the registered public offering
otherwise agree, and (ii) to cause each holder of Registrable Securities and
each other holder of at least 5% (on a fully diluted basis) of equity securities
of the Company, or any securities convertible into or exchangeable or
exercisable for such equity securities, purchased from the Company at any time
after the date hereof (other than in a registered public offering) to agree

                                      -8-
<PAGE>   9
not to effect any public sale or distribution (including sales pursuant to Rule
144) of any such securities during such period (except as part of such
underwritten registration, if otherwise permitted), unless the underwriters
managing the registered public offering otherwise agree.

                  5. Registration Procedures. Whenever the holders of
Registrable Securities have requested that any Registrable Securities be
registered pursuant to this Agreement, the Company will use its best efforts to
effect the registration and the sale of such Registrable Securities in
accordance with the intended method of disposition thereof, and pursuant thereto
the Company will as expeditiously as possible:

                  (a) prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective (provided that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company will furnish to the counsel selected by the holders of a majority of
the Registrable Securities covered by such registration statement copies of all
such documents proposed to be filed);

                  (b) prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
a period of not less than six months and comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of disposition by the sellers thereof set forth in such registration
statement;

                  (c) furnish to each seller of Registrable Securities such
number of copies of such registration statement, each amendment and supplement
thereto, the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

                  (d) use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller (provided that the Company will not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subsection, (ii) subject itself to
taxation in any such jurisdiction or (iii) consent to general service of process
(i.e., service of process which is not limited solely to securities law
violations) in any such jurisdiction);

                  (e) notify each seller of such Registrable Securities, at any
time when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such seller, the Company will
promptly prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such

                                      -9-
<PAGE>   10
Registrable Securities, such prospectus will not contain an untrue statement of
a material fact or omit to state any fact necessary to make the statements
therein not misleading;

                  (f) cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company, are then
listed and, if not so listed, to be listed on the Nasdaq National Market
("Nasdaq Market") and, if listed on the Nasdaq Market, use its best efforts to
secure designation of all such Registrable Securities covered by such
registration statement as a Nasdaq "National Market System security" within the
meaning of Rule 11Aa2-1 of the SEC or, failing that, to secure Nasdaq Market
authorization for such Registrable Securities and, without limiting the
generality of the foregoing, to arrange for at least two market makers to
register as such with respect to such Registrable Securities with the National
Association of Securities Dealers;

                  (g) provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such registration
statement;

                  (h) enter into such customary agreements (including
underwriting agreements in customary form) and take all such other actions as
the holders of a majority of the Registrable Securities being sold or the
underwriters, if any, reasonably request in order to expedite or facilitate the
disposition of such Registrable Securities (including, without limitation,
effecting a stock split or a combination of shares);

                  (i) make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the officers,
directors, employees and independent accountants of the Company to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement;

                  (j) otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, an earning statement covering the
period of at least twelve months beginning with the first day of the first full
calendar quarter of the Company, as applicable, after the effective date of the
registration statement, which earning statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

                  (k) permit any holder of Registrable Securities which holder,
in its sole and exclusive judgment, might be deemed to be an underwriter or a
controlling person of the Company to participate in the preparation of such
registration or comparable statement and to require the insertion therein of
material, furnished to the Company, in writing, which in the reasonable judgment
of such holder and its counsel should be included;

                  (l) in the event of the issuance of any stop order suspending
the effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any securities included in such registration statement for sale in

                                      -10-
<PAGE>   11
any jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order;

                  (m) use its best efforts to cause such Registrable Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
sellers thereof to consummate the disposition of such Registrable Securities;
and

                  (n) obtain a "cold comfort" letter from the independent public
accountants of the Company in customary form and covering such matters of the
type customarily covered by "cold comfort" letters as the holders of a majority
of the Registrable Securities being sold reasonably request.

If any such registration or comparable statement refers to any holder by name or
otherwise as the holder of any securities of the Company, and if, in its sole
and exclusive judgment, such holder is or might be deemed to be a controlling
Person of the Company, such holder shall have the right to require (i) the
insertion therein of language, in form and substance satisfactory to such holder
and presented to the Company, in writing, to the effect that the holding by such
holder of such securities is not to be construed as a recommendation by such
holder of the investment quality of the Company's securities covered thereby and
that such holding does not imply that such holder will assist in meeting any
future financial requirements of the Company, or (ii) in the event that such
reference to such holder by name or otherwise is not required by the Securities
Act or any similar Federal statute then in force, the deletion of the reference
to such holder; provided, that with respect to this clause (ii) such holder
shall furnish to the Company, an opinion of counsel to such effect, which
opinion and counsel shall be reasonably satisfactory to the Company.

                  6.  Registration Expenses.

                  (a) All expenses incident to the Company's performance of or
compliance with this Agreement, including without limitation all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, and fees and
disbursements of counsel for the Company, and all independent certified public
accountants, underwriters (excluding discounts and commissions) and other
Persons retained by the Company, will be borne by the Company, with respect to
any registration, proposed or otherwise, of its securities.

                  (b) In connection with each Demand Registration, each
Piggyback Registration and each 415 Registration, the Company will reimburse the
holders of Registrable Securities covered by such registration for the
reasonable fees and disbursements of one counsel chosen by the holders of a
majority of the Registrable Securities initially requesting such registration.

                  7.  Indemnification.

                  (a) The Company agrees to indemnify, to the extent permitted
by law, each holder of Registrable Securities, its respective partners, members,
officers and directors and each Person who controls such holder (within the
meaning of the Securities Act) against all losses, claims, damages, liabilities
and expenses arising out of or based upon any untrue or alleged untrue statement
of material fact contained in any registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse
such holder, director, officer or controlling Person for any legal or other
expenses reasonably incurred by such holder, director, officer or controlling
Person in connection with the investigation or defense of such loss, claim,
damage, liability or expense, except insofar as the same are caused by or
contained in any information furnished in writing to the Company by such holder
expressly for use therein or by such holder's failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto
after the Company has furnished such holder with a sufficient number of copies
of the same. In connection with an underwritten offering, the Company will
indemnify such underwriters, their officers and directors and each Person who
controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the holders
of Registrable Securities.

                  (b) In connection with any registration statement in which a
holder of Registrable Securities is participating, each such holder will furnish
to the Company in writing such information and affidavits as the Company
reasonably requests for use in connection with any such registration statement
or prospectus and, to the extent permitted by law, will indemnify the Company in
connection with any registration of Registrable Securities, and its members,
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act), as applicable, against any losses, claims,
damages, liabilities and expenses resulting from any untrue or alleged untrue
statement of material fact contained in such registration statement, prospectus
or preliminary prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent
that such untrue statement or omission is contained in any information or
affidavit so furnished in writing by such holder; provided, that the obligation
to indemnify will be individual to each holder and will be limited to the net
amount of proceeds received by such holder from the sale of Registrable
Securities pursuant to such registration statement.

                  (c) Any Person entitled to indemnification hereunder will (i)
give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one

                                      -12-
<PAGE>   13
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim.

                  (d) The indemnification provided for under this Agreement will
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any partner, member, officer, director or
controlling Person of such indemnified party and will survive the transfer of
securities. The Company, to the extent so liable, also agrees to make such
provisions, as are reasonably requested by any indemnified party, for
contribution to such party in the event that the Company's indemnification is
unavailable for any reason.

                  8. Participation in Underwritten Registrations. No Person may
participate in any registration hereunder which is underwritten unless such
Person (a) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (b) completes and executes all customary
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements; provided, that no holder of Registrable Securities included in any
underwritten registration shall be required to make any representations or
warranties to the Company or the underwriters other than representations and
warranties regarding such holder and such holder's intended method of
distribution.

                  9. Rule 144 Reporting. With a view to making available to the
holders of Registrable Securities the benefits of certain rules and regulations
of the SEC which may permit the sale of the Registrable Securities to the public
without registration, the Company agrees to use its best efforts to:

                  (a) make and keep current public information available, within
the meaning of Rule 144 or any similar or analogous rule promulgated under the
Securities Act, at all times after it has become subject to the reporting
requirements of the Exchange Act;

                  (b) file with the SEC, in a timely manner, all reports and
other documents required under the Securities Act and Exchange Act (after it has
become subject to such reporting requirements); and

                  (c) so long as any party hereto owns any Registrable
Securities, furnish to such Person forthwith upon request a written statement as
to its compliance with the reporting requirements of said Rule 144 (at any time
commencing 90 days after the effective date of the first registration filed by
the Company for an offering of its securities to the general public), the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements); a copy of its most recent annual or quarterly
report; and such other reports and documents as such Person may reasonably
request in availing itself of any rule or regulation of the SEC allowing it to
sell any such securities without registration.

                  10. Notices. All notices, demands or other communications to
be given or delivered under or by reason of the provisions of this Agreement
will be in writing and will be

                                      -13-

                                PURPOSE OF PLAN

     The 1997 Stock Option Plan (the "PLAN") of Centurion International, Inc.

Company effective April __, 1997, is intended to advance the best interests of
the Company by providing executives and other key employees of the Company or
any Subsidiary who have substantial responsibility for the management and
growth of the Company or any Subsidiary with additional incentives by allowing
such employees to acquire an ownership interest in the Company. The Plan is a
compensatory benefit plan within the meaning of Rule 701 under the Securities
Act of 1933, as amended (the "SECURITIES ACT").

                                   ARTICLE II

Option Shares hereunder.

transactions (other than sales in the ordinary course of business) or (ii)
merger or consolidation to which the Company is a party, other than a merger in

power (under ordinary circumstances) to elect a majority of the Board being

of such capital stock immediately prior to such merger.

                                  ARTICLE III

                                 ADMINISTRATION

     The Plan shall be administered by the Committee. Subject to the
limitations of the Plan, the Committee shall have the sole and complete
authority to: (i) select Participants, (ii) grant Options to Participants in
such forms and amounts as it shall determine, (iii) impose such limitations,
restrictions and conditions upon such Options as it shall deem appropriate,
(iv) interpret the Plan and adopt, amend, and rescind administrative
guidelines and other rules and regulations relating to the Plan, (v) correct
any defect or omission or reconcile any inconsistency in the Plan or in any
Options granted under the Plan and (vi) make all other determinations and take
all other actions necessary or advisable for the implementation and
administration of the Plan. The Committee's determinations on matters within
its authority shall be conclusive and binding upon the Participants, the
Company and all other persons. All expenses associated with the administration
of the Plan shall be borne by the Company. The Committee may, as approved by
the Board and to the extent permissible by law, delegate any of its authority
hereunder to such persons or entities as it deems appropriate.

                         LIMITATION ON AGGREGATE SHARES

     The number of shares of Common Stock with respect to which stock purchase
options ("OPTIONS") may be granted under the Plan shall not exceed, in the
aggregate, 1,000,000 shares, subject to adjustment in accordance with Section
6.4 below. To the extent any Options expire unexercised or are cancelled,
terminated or forfeited in any manner without the issuance of Common Stock
thereunder, such shares shall again be available under the Plan. The shares of
Common Stock available under the Plan may consist of authorized and unissued
shares, treasury shares, or a combination thereof, as the Committee shall
determine.

                                   ARTICLE V

                                     AWARDS

     5.1 GRANT OF OPTIONS. The Committee may grant Options to Participants from
time to time in accordance with this Article V. Options granted under the Plan
may be nonqualified stock options or "incentive stock options" within the
meaning of Section 422 of the Code or any successor provision, as specified by
the Committee; provided, however, that no incentive stock option may be granted
to any Participant who, at the time of grant, owns stock of the Company (or any
Subsidiary) representing more than 10% of the total combined voting power of all
classes of stock of the Company (or any Subsidiary), unless such incentive stock
option shall at the time of grant (a) have a termination date not later than the
fifth anniversary of the issuance date and (b) have an exercise price per share
equal to at least 110% of the Fair Market Value of a share of Common Stock on
the date of grant. The exercise price per share of Common Stock under each
incentive stock option shall be fixed by the Committee at the time of grant of
the Option and shall equal at least 100% of the Fair Market Value of a share of
Common Stock on the date of grant, but not less than the par value per share (as
adjusted pursuant to Section 6.4). Options shall be exercisable at such time or
times as the Committee shall determine; provided, however, that any option
intended to be an incentive stock option shall be treated as an incentive stock
option only to the extent that the aggregate Fair Market Value of the Common
Stock (determined as of the date of Option grant) with respect to which
incentive stock options (but not nonqualified options) are exercisable for the
first time by any Participant during any calendar year (under all stock option
plans of the Company and its Subsidiaries) does not exceed $100,000. The
Committee shall determine the term of each Option, which term shall not exceed
ten years from the date of grant of the Option.

     5.2 EXERCISE PROCEDURE. Options shall be exercisable, to the extent they
are vested, by written notice to the Company (to the attention of the Company's
Secretary) accompanied by payment in full of the applicable exercise price.
Payment of such exercise price may be made (i) in cash (including check, bank
draft, money order or wire transfer of immediately available funds), (ii) if
approved by the Committee prior to exercise (in the case of an incentive stock
option, if approved by the Committee in the grant) by delivery of a full
recourse promissory note of the Participant bearing interest at a rate not less
than the applicable federal rate determined pursuant to Section 1274 of the
Code, (iii) in shares of Common Stock valued at their Fair Market Value as of
the date of exercise as provided in Section 5.3 below, or (iii) in a
combination of the foregoing.

     5.3 EXCHANGE OF PREVIOUSLY ACQUIRED STOCK. The Committee, in its
discretion and subject to such conditions as the Committee may determine, may
permit the exercise price for the shares being acquired upon the exercise of an
Option to be paid, in full or in part, by the delivery to the Company of Common
Stock. Any Common Stock so delivered shall be treated as the payment of cash
equal to the aggregate Fair Market Value of such Common Stock. In the case of
incentive stock options, the Committee shall specify in the Option grant
whether the option holder may satisfy the exercise price with respect to shares
of Common Stock purchased upon exercise of such Option by delivering to the
Company shares of previously acquired Common Stock.

     5.4 WITHHOLDING TAX REQUIREMENTS.

                                      -4-

<PAGE>   6
     (a)  AMOUNT OF WITHHOLDING. It shall be a condition of the exercise of any
Option that the Participant exercising the Option make appropriate payment or
other provision acceptable to the Company with respect to any withholding tax
requirement arising from such exercise. The amount of withholding tax required,
if any, with respect to any Option exercise (the "WITHHOLDING AMOUNT") shall be
determined by the Treasurer or other appropriate officer of the Company, and
the Participant shall furnish such information and make such representations as
such officer requires to make such determination.

     (b) WITHHOLDING PROCEDURE. If the Company determines that withholding tax
is required with respect to any exercise of an Option, the Company shall notify
the Participant of the Withholding Amount, and the Participant shall pay to the
Company an amount not less than the Withholding Amount. In lieu of making such
payment, the Participant may elect to pay the Withholding Amount by either (i)
delivering to the Company a number of shares of Common Stock having an aggregate
Fair Market Value as of the Measurement Date not less than the Withholding
Amount or (ii) directing the Company to withhold (and not to deliver or issue to
the Participant) a number of shares of Common Stock, otherwise issuable upon the
exercise of an Option, having an aggregate Fair Market Value as of the
Measurement Date not less than the Withholding Amount. In addition, if the
Committee approves, a Participant may elect pursuant to the prior sentence to
deliver or direct the withholding of shares of Common Stock having an aggregate
Fair Market Value in excess of the minimum Withholding Amount but not in excess
of the Participant's applicable highest marginal combined federal income and
state income tax rate, as estimated in good faith by such Participant. Any
fractional share interests resulting from the delivery or withholding of shares
of Common Stock to meet withholding tax requirements shall be settled in cash.
All amounts paid to or withheld by the Company and the value of all shares of
Common Stock delivered to or withheld by the Company pursuant to this Section
5.4 shall be deposited in accordance with applicable law by the Company as
withholding tax for the Participant's account. If the Treasurer or other
appropriate officer of the Company determines that no withholding tax is
required with respect to the exercise of any Option (because such Option is an
incentive stock option or otherwise), but subsequently it is determined that the
exercise resulted in taxable income as to which withholding is required (as a
result of a disposition of shares or otherwise), the Participant shall promptly,
upon being notified of the withholding requirement, pay to the Company, by means
acceptable to the Company, the amount required to be withheld; and at its
election the Company may condition the transfer of any shares issued upon
exercise of an incentive stock option upon receipt of such payment.

     5.5  NOTIFICATION OF INQUIRIES AND AGREEMENTS. Each Participant and each
Permitted Transferee shall notify the Company in writing within 10 days after
the date such Participant or Permitted Transferee (i) first obtains
knowledge of any Internal Revenue Service inquiry, audit, assertion,
determination, investigation, or question relating in any manner to the value
of Options granted hereunder; (ii) includes or agrees (including, without
limitation, in any settlement, closing or other similar agreement) to include
in gross income with respect to any Option granted under this Plan (A) any
amount in excess of the amount reported on Form 1099 or Form W-2 to such
Participant by the Company, or (B) if no such Form was received, any amount;
and/or (iii) exercises, sells, disposes of, or otherwise transfers an Option
acquired pursuant to this Plan. Upon request, a Participant or Permitted
Transferee shall provide to the Company any information or document relating to
any event described in the preceding sentence which the Company (in its sole
discretion) requires in order to calculate and substantiate any change in the
Company's tax liability as a result of such event.

                                        -5-

<PAGE>   7
 5.6  CONDITIONS AND LIMITATIONS ON EXERCISE. At the discretion of the
Committee, exercised at the time of grant, Options may vest, in one or more
installments, upon (i) the fulfillment of certain conditions, (ii) the passage
of a specified period of time, and/or (iii) the achievement by the Company or
any Subsidiary of certain performance goals. Unless the Committee specifies
otherwise in the Option Agreement, the Option shall vest with respect to 25% of
the Option Shares subject to such Option on each of the first through the fourth
annual anniversaries of the date of grant. In the event of a Sale of the
Company, the Committee may provide, in its discretion, that the Options shall
become immediately vested and that such Options shall terminate if not exercised
as of the date of the Sale of the Company or any other designated date (the
"DESIGNATED DATE") or that such Options shall thereafter represent only the
right to receive the excess of the consideration per share of Common Stock
offered in such Sale of the Company over the exercise price of such Options. The
Company shall give all Participants notice of an impending Sale of the Company
at least 15 days prior to the date of such Sale of the Company or the Designated
Date, whichever is earlier.

     5.7  EXPIRATION OF OPTIONS.

          (a)  NORMAL EXPIRATION. In no event shall any part of any Option be
exercisable after the stated date of expiration thereof.

          (b)  EARLY EXPIRATION UPON TERMINATION OF EMPLOYMENT. Any part of any
Option that was not vested on a Participant's Termination Date shall expire and
be forfeited on such date, and any part of any Option that was vested on the
Termination Date shall also expire and be forfeited to the extent not
theretofore exercised on the thirtieth (30th) day (one year if termination is
caused by the Participant's death or disability) following the Termination
Date, but in no event after the stated date of expiration thereof.

     5.8  RIGHT TO PURCHASE OPTION SHARES UPON TERMINATION OF EMPLOYMENT.

          (a)  REPURCHASE RIGHT. In the event a Participant's employment with
the Company is terminated for any reason, the Option Shares (whether held by
such Participant or one or more transferees and including any Option Shares
acquired subsequent to such termination of employment) will be subject to
repurchase by the Company pursuant to the terms and conditions set forth in
this Section 5.8 (the "REPURCHASE OPTION") at a price per share equal to the
Fair Market Value thereof determined as of the Termination Date.

          (b)  REPURCHASE NOTICE. The Board may elect to purchase all or any
portion of the Option Shares by delivery of written notice (the "REPURCHASE
NOTICE") to the holder or holders of the Option Shares within 180 days after
the Termination Date. The Repurchase Notice will set forth the number of Option
Shares to be acquired from such holder, the aggregate consideration to be paid
for such shares and the time and place for the closing of the transaction.

          (c)  CLOSING OF REPURCHASE. The closing of the repurchase transaction
will take place on the date designated by the Company in the Repurchase Notice,
which date will not be more than 45 days nor less than 10 days after the
delivery of such notice. The Company will pay for the Option Shares to be
purchased pursuant to the Repurchase Option by delivering, at the option of the
Company to such Participant and/or the other holder(s), (1) a check in the
amount of the aggregate sale price of the Option Shares to be repurchased or
(2) if the aggregate consideration to be paid to such holder(s) of Option
Shares exceeds $50,000, a check

                                      -6-

in the amount of 20% of the aggregate sale price of the Option Shares to be
repurchased and a subordinated promissory note in a principal amount equal to
the remainder of the aggregate sale price, bearing interest at a floating rate
of interest equal to the prime rate as stated from time to time by Chase
Manhattan Bank or any successor thereto, and payable, as to principal and
interest, in four equal annual installments on the first four anniversaries of
the closing of such repurchase; provided that if the Company determines that
withholding tax is required with respect to the exercise of a Repurchase
Option, the Company shall withhold an amount equal to such withholding tax from
the purchase price. At the closing, the Participant and each other seller will
deliver the certificates representing the Option Shares to be sold duly
endorsed in form for transfer to the Company or its designee, and the Company
will be entitled to receive customary representations and warranties from the
Participant and the other sellers regarding title to the Option Shares.

     5.9  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS.  A Participant may not sell, pledge or otherwise
transfer any interest in any Option Shares except pursuant to the provisions of
this Section 5.9. At least 60 days prior to making any transfer, the
Participant proposing such transfer shall deliver a written notice (the "SALE
NOTICE") to the Company. The Sale Notice will disclose in reasonable detail
the identity of the prospective transferee(s) and the terms and conditions of
the proposed transfer. Such Participant (and such Participant's transferees)
shall not consummate any such transfer until 60 days after the Sale Notice has
been delivered to the Company unless the Company has notified such Participant
in writing that it will not exercise its rights under this Section 5.9. (The
date of the first to occur of such events is referred to herein as the
"AUTHORIZATION DATE").

          (b)  REPURCHASE OPTION.  The Company may elect to purchase all or any
portion of the Option Shares to be transferred upon the same terms and
conditions as those set forth in the Sale Notice (the "RIGHT OF FIRST REFUSAL")
by delivering a written notice of such election to such Participant within 30
days after the receipt of the Sale Notice by the Company (the "ELECTION
NOTICE"). If the Company has not elected to purchase all of the Option Shares
specified in the Sale Notice, such Participant may transfer the Option Shares
not purchased by the Company to the prospective transferee(s) as specified in
the Sale Notice at a price and on terms no more favorable to the transferee(s)
thereof than specified in the Sale Notice during the 60-day period immediately
following the Authorization Date. Any Option Shares not so transferred within
such 60-day period must be reoffered to the Company in accordance with the
provisions of this Section 5.9 in connection with any subsequent proposed
transfer.

          (c)  EXCEPTIONS.  The restrictions contained in this Section 5.9 will
not apply with respect to transfers of Option Shares (1) pursuant to applicable
laws of descent and distribution or (2) among the Participant's family group;
provided that the restrictions contained in this paragraph will continue to be
applicable to the Option Shares after any such transfer and the transferees of
such Option Shares have agreed in writing to be bound by the terms and
provisions of this Plan and the Option grant, as amended from time to time. The
Participant's "family group" means the Participant's spouse and descendants
(whether natural or adopted) and any trust solely for the benefit of the
Participant and/or the Participant's spouse and/or descendants.

     5.10  TERMINATION OF RESTRICTIONS.  The rights and obligations set forth
in Sections 5.8 and 5.9 hereof will terminate upon the earlier of (A) the
consummation by the Company of a Public Offering or (B) the sale of Option
Shares in accordance with the terms and conditions of Section 5.9 (except for a
transfer pursuant

                                      -7-
<PAGE>   9
to Section 5.9(c)); provided that with respect to clause (B) above, such rights
and obligations shall terminate only with respect to those Option Shares sold.

                                   ARTICLE VI

                               GENERAL PROVISIONS

     6.1  WRITTEN AGREEMENT. Each Option granted hereunder shall be embodied in
a written agreement (the "OPTION AGREEMENT") which shall be signed by the
Participant to whom the Option is granted and shall be subject to the terms and
conditions set forth herein.

     6.2  LISTING, REGISTRATION AND LEGAL COMPLIANCE. If at any time the
Committee determines, in its discretion, that the listing, registration, or
qualification of the shares subject to Options upon any securities exchange or
under any state or federal securities or other law or regulation, or the
consent or approval of any governmental regulatory body, is necessary or
desirable as a condition to or in connection with the granting of Options or
the purchase or issuance of shares thereunder, no Options may be granted or
exercised, in whole or in part, unless such listing, registration,
qualification, consent or approval shall have been effected or obtained free of
any conditions not acceptable to the Committee. The holders of such Options
will supply the Company with such certificates, representations and information
as the Company shall request and shall otherwise cooperate with the Company in
obtaining such listing, registration, qualification, consent or approval. In
the case of officers and other persons subject to Section 16(b) of the
Securities Exchange Act of 1934, as amended, the Committee may at any time
impose any limitations upon the exercise of Options that, in the Committee's
discretion, are necessary or desirable in order to comply with such Section
16(b) and the rules and regulations hereunder. If the Company, as part of an
offering of securities or otherwise, finds it desirable because of federal or
state regulatory requirements to reduce the period during which any Options may
be exercised, the Committee may, in its discretion and without the
Participant's consent, so reduce such period on not less than 15 days' written
notice to the holders thereof.

     6.3  OPTIONS NOT TRANSFERRABLE. Options may not be transferred other than
by will or the laws of descent and distribution and, during the lifetime of the
Participant to whom they were granted, may be exercised only by such
Participant (or, if such Participant is incapacitated, by such Participant's
legal guardian or legal representative). In the event of the death of a
Participant, Options which are not vested on the date of death shall terminate;
exercise of Options granted hereunder to such Participant, which are vested as
of the date of death, may be made only by the executor or administrator of such
Participant's estate or the person or persons to whom such Participant's rights
under the Options will pass by will or the laws of descent and distribution.

     6.4  ADJUSTMENTS. In the event of a reorganization, recapitalization,
stock dividend or stock split, or combination or other change in the shares of
Common Stock, the Board or the Committee may, in order to prevent the dilution
or enlargement of rights under the Plan or outstanding Options, adjust (i) the
number and type of shares as to which options may be granted under the Plan,
(ii) the number and type of shares covered by outstanding Options, (iii) the
exercise prices specified therein and (iv) other provisions of this Plan which
specify a number of shares, all as such Board or Committee determines to be
appropriate and equitable.

                                     - 8 -

     6.5  RIGHTS OF PARTICIPANTS. Nothing in the Plan shall interfere with or
limit in any way the right of the Company or any Subsidiary to terminate any
Participant's employment at any time (with or without cause), or confer upon any
Participant any right to continue in the employ of the Company or any Subsidiary
for any period of time or to continue to receive such Participant's current (or
other) rate of compensation. No employee shall have a right to be selected as a
Participant or, having been so selected, to be selected again as a Participant.

     6.6  AMENDMENT, SUSPENSION AND TERMINATION OF PLAN.  The Board or the
Committee may suspend or terminate the Plan or any portion thereof at any time
and may amend it from time to time in such respects as the Board or the
Committee may deem advisable; provided, however, that no such amendment shall be
made without stockholder approval to the extent such approval is required by
law, agreement or the rules of any exchange upon which the Common Stock is
listed, and no such amendment, suspension or termination shall impair the rights
of Participants under outstanding Options without the consent of the
Participants affected thereby, except as provided below. No Options shall be
granted hereunder after the tenth anniversary of the adoption of the Plan.

     6.7  AMENDMENT OF OUTSTANDING OPTIONS.  The Committee may amend or modify
any Option in any manner to the extent that the Committee would have had the
authority under the Plan initially to grant such Option; provided that, except
as expressly contemplated elsewhere herein or in any agreement evidencing such
Option, no such amendment or modification shall impair the rights of any
Participant under any outstanding Option without the consent of such
Participant.

     6.8  INDEMNIFICATION.  In addition to such other rights of indemnification
as they may have as members of the Board or the Committee, the members of the
Committee shall be indemnified by the Company against (i) all costs and expenses
reasonably incurred by them in connection with any action, suit or proceeding to
which they or any of them may be party by reason of any action taken or failure
to act under or in connection with the Plan or any Option granted under the
Plan, and (ii) all amounts paid by them in settlement thereof (provided such
settlement is approved by independent legal counsel selected by the Company) or
paid by them in satisfaction of a judgment in any such action, suit or
proceeding; provided, however, that any such Committee member shall be entitled
to the indemnification rights set forth in this Section 6.8 only if such member
(1) acted in good faith and in a manner that such member reasonably believed to
be in, and not opposed to, the best interests of the Company, and (2) with
respect to any criminal action or proceeding, (A) had no reasonable cause to
believe that such conduct was unlawful, and (B) upon the institution of any such
action, suit or proceeding a Committee member shall give the Company written
notice thereof and an opportunity to handle and defend the same before such
Committee member undertakes to handle and defend it on his own behalf.

     6.9  RESTRICTED SECURITIES.  All Common Stock issued pursuant to the terms
of this Plan shall constitute "restricted securities," as that term is defined
in Rule 144 promulgated by the Securities and Exchange Commission pursuant to
the Securities Act, and may not be transferred except in compliance with the
registration requirements of the Securities Act or an exemption therefrom.
