         SECTION 2. Required Registration.

         (a) Buyer shall prepare and file or cause to be prepared and filed with
the SEC (1) as soon as practicable, but in any event within sixty (60) days
after the Closing Date, a registration statement for an offering to be made on a
delayed or continuous basis pursuant to Rule 415 of the Securities Act
registering (A) the resale from time to time by the Shareholders thereof of all
of the Registrable Shares delivered at the Closing or otherwise capable of being
registered at such time and (B) the issuance by Buyer of Buyer Stock upon
exercise of any Buyer Options delivered at the Closing, and (2) if necessary, as
soon as practicable, but in any event within sixty (60) days after each
Subsequent Event an additional registration statement for an offering to be made
on a delayed or continuous basis pursuant to Rule 415 of the Securities Act
registering (x) the resale from time to time of any additional Registrable
Shares delivered upon the occurrence of a Subsequent Event and (y) the issuance
by Buyer of Buyer Stock upon exercise of any Buyer Options delivered upon the
occurrence of a Subsequent Event. (Each registration statement required to be
filed pursuant to the preceding sentence, a "Shelf Registration Statement".)
Each Shelf Registration Statement shall be on Form S-3 or another appropriate
form permitting registration of such Registrable Shares for resale by such
Shareholders in accordance with the methods of distribution elected by the
Shareholders and set forth in such Shelf Registration Statement. Buyer shall use
its commercially reasonable efforts to cause each Shelf Registration Statement
to be declared effective under the Securities Act as promptly as is practicable
after the filing thereof with the SEC, but in any event within ninety (90) days
after the Closing Date or the relevant Subsequent Delivery Date, as the case may
be, and to keep such Shelf Registration Statement continuously effective under
the Securities Act until the expiration of the Effectiveness Period.
Notwithstanding the foregoing sentence, in the event that the staff of the SEC
notifies Buyer or its counsel (whether orally or in writing) that a Shelf
Registration Statement will not be reviewed ("No-Review"), the Buyer shall
notify each Shareholder within five (5) Business Days of such notification and
use its commercially reasonable efforts to cause such Shelf Registration
Statement to be declared effective (including by requesting acceleration of the
Shelf Registration Statement) no later than fifteen (15) days after receipt of
such notification from the staff of the SEC.

         At the time a Shelf Registration Statement is declared effective, each
Shareholder that became a Notice

                                       4
<PAGE>   5
Shareholder on or prior to the date ten (10) Business Days (or in the event of a
No-Review, five (5) Business Days) prior to such time of effectiveness shall be
named as a selling securityholder in such Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Shareholder to deliver
such Prospectus to purchasers of Registrable Shares in accordance with
applicable law.

         In the event that any public offering pursuant to this Agreement shall
involve, in whole or in part, an underwritten offering (which shall require the
prior consent of Buyer), Buyer shall have the right to designate an underwriter
or underwriters as the lead or managing underwriter(s) of such underwritten
offering who shall be reasonably acceptable to Shareholders owning a majority of
the Registrable Shares proposed to be sold therein. Each Shareholder agrees that
if such Shareholder's Registrable Shares, or any portion thereof, are sold in
any public offering involving, in whole or in part, an underwritten offering,
then such Shareholder will enter into a customary underwriting agreement with
the underwriter(s) selected pursuant to the preceding sentence.

         Notwithstanding the foregoing, Buyer may delay in filing any Shelf
Registration Statement and may withhold efforts to cause such Shelf Registration
Statement to become effective if the Buyer determines in good faith that such
filing or effectiveness might (1) interfere with or affect the negotiation or
completion of any transaction or other material event that is being contemplated
by Buyer (whether or not a final decision has been made to undertake such
transaction at the time the right to delay is exercised), or (2) involve initial
or continuing disclosure obligations that might not be in the best interest of
Buyer's shareowners. Buyer may exercise such right to delay the filing or
effectiveness of each registration statement one time and may delay the filing
or effectiveness of such Shelf Registration Statement for not more than sixty
(60) days beyond the relevant period set forth in the first paragraph of this
Section 2(a).

         (b) Following the effectiveness of a Shelf Registration Statement filed
pursuant to this Section 2, Buyer may suspend at any time the availability of
such Shelf Registration Statement and the related Prospectus upon (i) the
issuance by the SEC of a stop order with respect to such Shelf Registration
Statement or the initiation of proceedings with respect to such Shelf
Registration Statement under Section 8(d) or 8(e) of the Securities Act, (ii)
the occurrence of any event or the existence of any fact as a result of which
(A) any Shelf Registration

                                       5
<PAGE>   6
Statement shall contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading, or (B) any Prospectus shall contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, or (iii) the
occurrence or existence of any pending corporate development, including without
limitation any such development that may (y) interfere with or affect the
negotiation or completion of any transaction or other material event that is
being contemplated by Buyer (whether or not a final decision has been made to
undertake such transaction at the time the right to suspend is exercised), or
(z) involve initial or continuing disclosure obligations that might not be in
the best interest of Buyer's shareowners, that, in the reasonable discretion of
Buyer, makes it appropriate to suspend the availability of any Shelf
Registration Statement and the related Prospectus (each of (i), (ii) and (iii)
above is hereinafter referred to as a "Suspension Period"); provided that the
duration of a Suspension Period under subsections (ii) and (iii) shall not
extend beyond thirty (30) days. Notwithstanding the foregoing, Buyer shall be
limited to no more than two Suspension Periods under subsections (ii) and (iii)
above in any rolling 12-month period. Buyer shall use its reasonable efforts to
end any Suspension Period as promptly as practicable under the circumstances
and, in the case of subsection (iii) above, as soon as, in the discretion of
Buyer, such suspension is no longer appropriate.

         Provided that a Shareholder has timely delivered to Buyer a Notice and
Questionnaire, Buyer shall be obligated to notify such Shareholder in writing of
the existence of a Suspension Period. Upon receipt of any notice from Buyer of a
Suspension Period, the Shareholders shall forthwith discontinue any disposition
of Registrable Shares until the earlier of (1) the end of the Suspension Period
or (2) the Shareholders (i) are advised in writing by Buyer that the use of the
applicable Prospectus may be resumed, (ii) have received copies of a
supplemental or amended Prospectus, if applicable, and (iii) have received
copies of any additional or supplemental filings which are incorporated or
deemed to be incorporated by reference into such Prospectus.

         (c) The Shareholders acknowledge that Buyer's obligations under this
Section 2 may be satisfied, in Buyer's sole discretion, by the inclusion of the
Registrable Shares in any eligible registration statement filed by Buyer

                                       6
<PAGE>   7
for the benefit of any of its shareowners other than the Shareholders or by the
amendment of any existing Shelf Registration Statement.

         (d) In the event that any Shelf Registration Statement shall cease to
be effective, Buyer shall promptly prepare and file a new registration statement
covering the Registrable Shares previously covered by such Shelf Registration
and shall use its best efforts to have such registration statement declared
effective as soon as possible. Any such registration statement shall be
considered a "Shelf Registration Statement" hereunder.

         (e) Each Shareholder who wishes to sell Registrable Shares pursuant to
a Shelf Registration Statement and related Prospectus agrees that it will do so
only in accordance with Section 2(b) and this Section 2(e). Each Shareholder
wishing to sell Registrable Shares pursuant to a Shelf Registration Statement
and related Prospectus agrees to deliver a Notice and Questionnaire to Buyer at
least ten (10) Business Days prior to any intended distribution of Registrable
Shares under the Shelf Registration Statement (or in the event of a No-Review,
five (5) Business Days prior to the date the Shelf Registration Statement is
expected to be declared effective). From and after the date any Shelf
Registration Statement is declared effective, Buyer shall, as promptly as
practicable after the date a Notice and Questionnaire is delivered, and in any
event within ten (10) Business Days after such date, if required by applicable
law, file with the SEC a post-effective amendment to such Shelf Registration
Statement or prepare and, if required by applicable law, file a supplement to
the related Prospectus or a supplement or amendment to any document incorporated
therein by reference or file any other required document so that the Shareholder
delivering such Notice and Questionnaire is named as a selling securityholder in
such Shelf Registration Statement and the related Prospectus in such a manner as
to permit such Shareholder to deliver such Prospectus to purchasers of the
Registrable Shares in accordance with applicable law and, if Buyer shall file a
post-effective amendment to the Shelf Registration Statement, use reasonable
efforts to cause such post-effective amendment to be declared effective under
the Securities Act as promptly as is practicable, but in any event by the date
(the "Amendment Effectiveness Deadline Date") that is forty-five (45) days after
the date such post-effective amendment is required by this clause to be filed;
provided that if such Notice and Questionnaire is delivered during a Suspension
Period, Buyer shall take the actions set forth above as soon as possible upon
expiration of the Suspension Period. Notwithstanding anything

                                       7
<PAGE>   8
contained herein to the contrary, (i) Buyer shall be under no obligation to name
any Shareholder that is not a Notice Shareholder as a selling securityholder in
any Registration Statement or related Prospectus and (ii) the Amendment
Effectiveness Deadline Date shall be extended by up to ten (10) Business Days
from the expiration of a Suspension Period if such Suspension Period shall be in
effect on the Amendment Effectiveness Deadline Date.

         SECTION 3. Liquidated Damages.

         (a) If the Shelf Registration Statement to be filed pursuant to Section
2(a)(1) of this Schedule 7.4(a) (the "Initial Shelf Registration Statement") has
not been declared effective by the SEC on or prior to the 90th day after the
Closing Date (the "Initial Registration Deadline"), Buyer shall deposit in a
joint bank account maintained in The City of London selected by the Sellers'
Representative and reasonably satisfactory to Buyer (the "Account") an amount
equal to one-half of one percent (0.5%) of the Aggregate Closing Consideration
(the "Liquidated Damages Payment Amount") on each of the date (1) of the Initial
Registration Deadline, (2) which is thirty (30) days after the Initial
Registration Deadline and (3) which is sixty (60) days after the Initial
Registration Deadline. Any balance in the Account shall be invested in
accordance with such instructions as may be given by Buyer. If the Initial Shelf
Registration Statement has not been declared effective on or prior to the 180th
day after the Closing Date (the "Initial Registration Default"), Buyer and the
Shareholders agree that all amounts in the Account as of the date of the Initial
Registration Default shall be released to an account designated by the Sellers'
Representative, for the benefit of the Sellers (the "Sellers' Account") on the
next Business Day following the date of the Initial Registration Default.

         (b) For each 30-day period after the Initial Registration Default,
Buyer shall deposit the Liquidated Damages Payment Amount in the Account on the
first Business Day of any such 30 day period. Buyer and the Shareholders agree
that amounts deposited in the Account pursuant to this Section 3(b) shall be
released to the Sellers' Account at the end of every 30-day period thereafter
until such time as the Initial Registration Statement shall have been declared
effective.

         (c) If the Initial Shelf Registration Statement has been declared
effective on or prior to the 180th day after the Closing Date, Buyer and the
Shareholders agree that all amounts in the Account, together with any interest

                                       8
<PAGE>   9
thereon, shall be released to Buyer on the next Business Day immediately
following the day that the Initial Registration Statement is declared effective.
If the Initial Registration Statement is declared effective on or prior to the
end of any thirty (30) day period following the 180th day after the Closing
Date, the Shareholders and Buyer agree that amounts then held in the Account for
payment under Section 3(b), together with interest thereon, shall be released to
Buyer.

         (d) If (i) any Shelf Registration Statement other than the Initial
Shelf Registration Statement (a "Subsequent Shelf Registration Statement") has
not been declared effective by the SEC on or prior to the date specified in
Section 2(a)(2) of this Schedule 7.4(a) or (ii) if any Subsequent Shelf
Registration Statement is filed and declared effective but shall thereafter
cease to be effective or fail to be usable for any period of thirty (30)
consecutive days other than as a result of a Suspension Period (each a
"Subsequent Registration Default"), Buyer agrees to pay liquidated damages in an
amount equal to $1.50 per share per annum for all Registrable Shares subject to
such Subsequent Shelf Registration Statement, which shall accrue from the date
such Subsequent Registration Default occurs until the default is cured. All
liquidated damages accrued and unpaid under this Section (3)(d) shall be paid on
the last day of each month following such default or, if earlier, the date the
relevant Subsequent Registration Default is cured.

         SECTION 4. Registration Procedures. When Buyer effects the registration
of the Registrable Shares under the Securities Act pursuant to Section 2 hereof,
Buyer will, at its expense, as promptly as practicable:

         (a) Subject to Section 2(e) and in accordance with the Securities Act
and the rules and regulations of the SEC, prepare and file with the SEC such
amendments to each Shelf Registration Statement and supplements to the
Prospectus contained therein as may be necessary to keep such Shelf Registration
Statement effective for the Effectiveness Period and such Shelf Registration
Statement and Prospectus accurate and complete for the Effectiveness Period;

         (b) Furnish to the Shareholders such reasonable number of copies of
each Shelf Registration Statement (including exhibits), any preliminary or final
Prospectus, any amendment or supplement to any of the foregoing and such other
documents as the Shareholders may reasonably request, including any documents

a general consent to service of process or to qualify to do business as a
foreign corporation in any jurisdiction where it is not so qualified;

         (d) Notify the Shareholders, (i) promptly after it shall receive notice

any event which would cause any such Prospectus or any other Prospectus as then
in effect to include an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, and promptly prepare and file with the SEC, and promptly
notify the Shareholders of the filing of, such amendments or supplements to any
Shelf Registration Statement or Prospectus as may be necessary to correct any
such statements or omissions;

         (g) Advise the Shareholders, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the SEC
suspending the effectiveness of any Shelf Registration Statement or the
initiation or threatening of any proceeding for that purpose and promptly use
its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal if such stop order should be issued;

         (i) Permit a single firm of counsel designated by the Shareholders
(which initially shall be Weil, Gotshal & Manges) a reasonable period of time
prior to the filing of the Shelf Registration Statement with the SEC to review
any Shelf Registration Statement, and shall not file such Shelf Registration
Statement in a form to which such counsel reasonably objects;

         (j) Provide such information as is required for any filings required to
be made with the National Association of Securities Dealers, Inc.; and

         (k) Otherwise use commercially reasonable efforts to comply with all

Shareholders, as soon as reasonably practicable, an earning statement covering

statement shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder.

         SECTION 5. Expenses. With respect to any registration effected pursuant
to Section 2 hereof, all fees, costs and expenses of and incidental to such
registration and the public offering in connection therewith, including the
reasonable fees and expenses of one firm of counsel for the Shareholders, shall
be borne by Buyer; provided, however, that the Shareholders shall bear their own
underwriting discounts or commissions, selling or placement agent or broker fees
and commissions, and transfer taxes, if any, in connection with the sales of
securities by such Shareholders.

         SECTION 6. Indemnification.

         (a) By Buyer. Buyer will indemnify each Shareholder and each of its
officers, directors, stockholders, partners, employees and agents and each
person controlling such Shareholder within the meaning of Section 15 of the

has been effected pursuant to this Schedule 7.4(a), against all expenses,
claims, losses, damages and liabilities (or actions in respect thereof),
including any of the foregoing incurred in

                                       11
<PAGE>   12
settlement of any litigation (including reasonable attorneys' fees), arising out
of or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any Shelf Registration Statement or Prospectus (including, in
each case, all documents incorporated by reference therein, as such documents
may have been updated by later dated documents), or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, or any
violation by Buyer of any rule or regulation promulgated under the Securities
Act applicable to Buyer and relating to action or inaction required of Buyer in
connection with any such registration, qualification or compliance; provided,
however, that Buyer will not be liable in any such case to the extent that any
such claim, loss, damage, liability or expense arises out of or is based on any
untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with written information furnished to Buyer by
such Shareholder and stated to be specifically for use therein or by a
Shareholder's failure to deliver a copy of the relevant Shelf Registration
Statement or Prospectus or any amendments or supplements thereto after Buyer has
furnished that Shareholder or underwriter with copies of the same. In connection
with a firm or best efforts underwritten offering, to the extent customarily
required by the managing underwriter, Buyer will indemnify the underwriters,
their officers and directors and each such person who controls the underwriters
(within the meaning of Section 15 of the Securities Act), to the extent
customary in such agreements.

         (b) By the Shareholders. Each Shareholder will, if Registrable Shares
held by such Shareholder are included in the securities as to which such
registration is being effected, indemnify Buyer, each of its directors,
officers, stockholders, partners, employees and agents and each person who
controls Buyer within the meaning of Section 15 of the Securities Act, and each
other such Shareholder, each of its officers, directors, partners, employees and
agents and each person controlling such Shareholder within the meaning of
Section 15 of the Securities Act, against all claims, losses, damages and
liabilities (or actions in respect thereof), including any of the foregoing
incurred in settlement of any litigation (including reasonable attorneys' fees),
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any Shelf Registration Statement or Prospectus,

                                       12
<PAGE>   13
or any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
to the extent, but only to the extent, that such untrue statement (or alleged
untrue statement) or omission (or alleged omission) is made in such Shelf
Registration Statement or Prospectus, in reliance upon and in conformity with
written information furnished to Buyer by such Shareholder and stated to be
specifically for use therein; provided, however, that the obligation to
indemnify will be individual to each Shareholder and shall be limited to an

best efforts underwritten offering, to the extent customarily required by the
managing underwriter, each Shareholder, severally and not jointly, will
indemnify the underwriters, their officers and directors and each person who
controls the underwriters (within the meaning of Section 15 of the Securities
Act), to the extent customary in such agreements; provided, however, that the
obligation to indemnify will be individual to each Shareholder and shall be

Registrable Shares sold in connection with such registration.

         (c) Each party entitled to indemnification under this Section 7 (the
"Schedule 7.4(a) Indemnified Party") shall give notice to the party required to
provide indemnification (the "Schedule 7.4(a) Indemnifying Party") promptly
after such Schedule 7.4(a) Indemnified Party has actual knowledge of any claim
as to which indemnity may be sought, and shall permit the Schedule 7.4(a)
Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom; provided that counsel for the Schedule 7.4(a) Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Schedule 7.4(a) Indemnified Party (which approval shall not be
unreasonably withheld), and the Schedule 7.4(a) Indemnified Party may
participate in such defense at such party's expense; provided, however, that the
Schedule 7.4(a) Indemnifying Party shall pay such expense if representation of
such Schedule 7.4(a) Indemnified Party by the counsel retained by the Schedule
7.4(a) Indemnifying Party would be inappropriate due to actual or potential
differing interests between the Schedule 7.4(a) Indemnified Party and any other
party represented by such counsel in such proceeding. The failure of any
Schedule 7.4(a) Indemnified Party to give notice as provided herein shall not
relieve the Schedule 7.4(a) Indemnifying Party of its obligations under this
Agreement, except to the extent, but only to the extent, that the Schedule
7.4(a) Indemnifying Party's ability to

                                       13
<PAGE>   14
defend against such claim or litigation is impaired as a result of such failure
to give notice. No Schedule 7.4(a) Indemnifying Party in the defense of any such
claim or litigation, shall, except with the consent of each Schedule 7.4(a)
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Schedule 7.4(a) Indemnified Party of a release
from all liability in respect to such claim or litigation.

         (d) If the indemnification provided for in this Section 7 is held by a
court of competent jurisdiction (by the entry of a final judgment or decree and
the expiration of time to appeal or the denial of the last right of appeal) to
be unavailable to a Schedule 7.4(a) Indemnified Party with respect to any loss,
liability, claim, damage, or expense referred to therein, then the Schedule
7.4(a) Indemnifying Party, in lieu of indemnifying such Schedule 7.4(a)
Indemnified Party hereunder, shall contribute to the amount paid or payable by
such Schedule 7.4(a) Indemnified Party as a result of such loss, liability,
claim, damage, or expense in such proportion as is appropriate to reflect the
relative fault of the Schedule 7.4(a) Indemnifying Party on the one hand and of
the Schedule 7.4(a) Indemnified Party on the other in connection with the
statements or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable considerations. The relative
fault of the Schedule 7.4(a) Indemnifying Party and of the Schedule 7.4(a)
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 to state a material fact relates to information supplied by the
Schedule 7.4(a) Indemnifying Party or by the Schedule 7.4(a) Indemnified Party
and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

         (e) The parties hereto agree that it would not be just and equitable if
contribution pursuant this Section 7 were determined by pro rata allocation or
by any other method of allocation that does not take account of the equitable
considerations referred to in Section 7(d). Notwithstanding anything herein to
the contrary, no participating holder of Registrable Shares will be required to
contribute any amount in excess of the amount by which the net proceeds received
by such participating holder from the sale of Registrable Shares pursuant to the
Shelf Registration Statement exceeds the amount of any damages that such
participating Shareholder has otherwise been

                                       14
<PAGE>   15
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person or entity guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) will be entitled to
contribution from any person or entity who was not guilty of such fraudulent
misrepresentation.

         (f) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in any underwriting agreement entered
into in connection with an underwritten public offering are in conflict with the
foregoing provisions, the provisions in the underwriting agreement shall
control.

         (g) The indemnification and contribution provided for under this
Schedule 7.4(a) will remain in full force and effect regardless of any
investigation made by or on behalf of the Schedule 7.4(a) Indemnified Party or
any officer, director or controlling person of the Schedule 7.4(a) Indemnified
Party and will survive the completion of any offering of Registrable Shares in
any Shelf Registration Statement under this Schedule 7.4(a).

         SECTION 7. Information by Shareholder. The Shareholder or Shareholders
wishing to sell any Registrable Shares in any registration shall furnish to
Buyer such information regarding such Shareholder or Shareholders and the
distribution proposed by such Shareholder or Shareholders as Buyer may request
in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Schedule 7.4(a).

         SECTION 8. Delay of Registration. The Shareholders shall not have any
right to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of these registration rights.

         SECTION 9. Rule 144. Buyer agrees that it will use its best efforts to
file with the SEC in a timely manner all reports and other documents required to
be filed by Buyer under the Securities Act and the Exchange Act and the rules
and regulations adopted by the SEC thereunder, to the extent required from time
to time, to enable each Shareholder to sell Registrable Shares without
registration under the Securities Act within the limitation of the exemptions
provided by (i) Rule 144, or (ii) any similar rule or regulation hereafter
adopted by the SEC, until the earlier to occur of the date (a) the Registrable
Shares covered thereby have been sold pursuant to a Shelf

                                       15
<PAGE>   16
Registration Statement, or (b) by which each Shareholder may sell all of its or
his Registrable Shares covered thereby under Rule 144(k). Buyer also agrees to
furnish to each Shareholder forthwith upon request any information which such
Shareholder may reasonably request in availing itself of Rule 144.

         SECTION 10. Termination of Buyer's Obligations. Buyer shall have no
obligations to register or maintain any Shelf Registration Statement governing
Registrable Shares and no penalties or liquidated damages will accrue or be
payable as a result of such failure to register or maintain any Shelf
Registration Statement, (a) if all Registrable Shares have been registered and
sold pursuant to a Shelf Registration Statement effected pursuant to this
Schedule 7.4(a), or (b) with respect to any particular Shareholder, at such time
as all Registrable Shares held by such Shareholder may be sold under Rule
144(k), as it may be amended from time to time, including but not limited to
amendments that reduce that period of time that securities must be held before
such securities may be sold pursuant to such Rule.

         SECTION 11. Successors and Assigns. This Schedule 7.4(a) shall inure to
the benefit of and be binding upon the successors and assigns of each of the
parties hereto including any person to whom Registrable Shares are transferred
in accordance with the provisions of the Stock Purchase Agreement.

         SECTION 12. Amendment and Waivers. Except as otherwise provided herein,
the provisions of this Schedule 7.4(a) may not be amended, modified or
supplemented, and waivers or consents to departure from the provisions hereof
may not be given unless agreed upon in writing by Buyer, the holders of a
majority of the Registrable Shares and the holders of a majority of the
Registrable Shares held by the Non-Warrantor Sellers.

                                                                   Exhibit 4.b.2

                                                                   Schedule 10.1

Registration Statement remains effective, the Effectiveness Period shall be

Buyer Stock upon any stock split or stock dividend or into which such shares of

consolidation, recapitalization or similar event until, in the case of any such
security, the earliest of (i) its effective registration under the Securities
Act and resale in accordance with the Registration Statement covering it, (ii)
expiration of the holding period that would be applicable thereto under Rule
144(k) were it not held by an Affiliate of Buyer or (iii) its sale pursuant to

filed with the SEC pursuant to a Demand Registration and/or Piggyback
Registration.

         "Rule 144" means Rule 144 under the Securities Act, as such Rule may be

         "Schedule 10.1 Indemnified Party" shall have the meaning set forth in

         "Schedule 10.1 Indemnifying Party" shall have the meaning set forth in

hereof.

         SECTION 2. Demand Registration.

         (a) Request for Registration. At any time during the Eligible Period,
Seller may demand once, by written notice to Buyer, that Buyer effect a
registration of all or part of its Registrable Shares under the Securities Act
(a "Demand Registration"), provided that the aggregate number of Registrable
Shares demanded to be registered have a market value of at least $5 million as
measured by the closing sale price of Buyer's Common Stock as reported by the
NASDAQ Stock Market on the NASDAQ trading day preceding the day of such demand.
Subject to Section 2(c) below, no later than 60 days following receipt by Buyer
of such written notice from Seller, Buyer shall prepare and file (or cause to be
filed) with the SEC a registration statement on Form S-3 (or any applicable
successor form) with respect to the sale by Seller of all such Registrable
Shares which Seller has requested to be registered (a "Demand Registration
Statement"), and Buyer will use its reasonable best efforts to have such Demand
Registration Statement declared effective within 90 days following receipt by
Buyer of such written notice from Seller.

                                    S 10.1-2
<PAGE>   3
         (b) Selection of Underwriters. In the event that in the sole discretion
of Buyer, any Demand Registration is effected in connection with any public
offering which shall involve, in whole or in part, an underwritten offering,
Buyer shall have the right to designate an underwriter or underwriters as the
lead or managing underwriter(s) of such underwritten offering. Seller agrees
that if any Registrable Shares are sold in connection with any public offering
involving, in whole or in part, an underwritten offering, then Seller will enter
into a customary underwriting agreement with the underwriter(s) selected
pursuant to the preceding sentence.

         (c) Delay in Filing. Notwithstanding the foregoing, Buyer may delay in
filing a Demand Registration Statement and may withhold efforts to cause such
Demand Registration Statement to become effective if Buyer determines in good
faith that such registration might (1) interfere with or affect the negotiation
or completion of any material transaction or other material event that is being
contemplated by Buyer (whether or not a final decision has been made to
undertake such material transaction at the time the right to delay is
exercised), or (2) involve initial or continuing disclosure obligations that
might not be in the best interest of Buyer's shareowners. Buyer may exercise
such right to delay the filing or effectiveness of a Demand Registration
Statement two times and may delay the filing or effectiveness of such
registration statement for not more than 90 days beyond the relevant period set
forth in Section 2(a). Upon any delay by Buyer pursuant to this Section 2(c)
which lasts more than 60 days, Seller may rescind its notice given pursuant to
Section 2(a), and Seller will be deemed not to have exercised its right to
effect a Demand Registration as a result of such notice.

         (d) Effective Demand Registration. A registration shall not constitute
a Demand Registration until the Demand Registration Statement has become
effective and, subject to Section 4(e)(i), remains continuously effective with
the SEC for the lesser of (i) the period during which all Registrable Shares
registered in the Demand Registration are sold and (ii) the Effectiveness
Period. Except as provided in Section 4(e)(i), in the event that a Demand
Registration Statement shall cease to be effective prior to such period, Buyer
shall promptly prepare and file a new Demand Registration Statement covering the
Registrable Shares previously covered by such Demand Registration Statement and
shall use its reasonable best efforts to have such new Demand Registration
Statement declared effective as soon as possible.

                                    S 10.1-3
<PAGE>   4
         (e) Satisfaction of Buyer's Obligation. Seller acknowledges that, after
Seller delivers a written notice to Buyer to effect a Demand Registration
pursuant to Section 2(a), Buyer's obligations under this Section 2 may be
satisfied, in Buyer's sole discretion, by the inclusion of the Registrable
Shares in any registration statement filed by Buyer for the benefit of Buyer or
any of its shareowners other than Seller. Seller will retain all rights provided
for herein applicable to a Demand Registration in connection with any Demand
Registration effected as described in this Section 2(e).

         SECTION 3. Piggyback Registrations.

         (a) Right to Piggyback. Whenever, during the period commencing on the
date of the Agreement and ending 18 months after the date of the Agreement,
Buyer proposes to register under the Securities Act on behalf of any of its
shareowners any shares of Common Stock of Buyer (except for the registration of
securities to be offered pursuant to an employee benefit plan on Form S-3 or
Form S-8 or pursuant to a registration made on Form S-4 or any successor forms
then in effect) at any time other than pursuant to a Demand Registration and the
registration form to be used may be used for the registration of the Registrable
Shares (a "Piggyback Registration"), Buyer will so notify Seller in writing no
later than 30 days prior to the filing date of a registration statement in
connection therewith. The notice shall offer to include in such filing the
amount of Registrable Shares as Seller may request. Seller shall (i) advise
Buyer in writing within 15 days after the date of receipt of such offer from
Buyer, setting forth the number of Registrable Shares for which registration is
requested, and (ii) deliver to Buyer a letter from counsel to Seller to the
effect that registration under the Securities Act is or may be required for the
sale of such Registrable Shares. Notwithstanding the foregoing, (i) Buyer hereby
notifies Seller that it is proposing to register under the Securities Act
certain shares of Common Stock of Buyer issued in connection with the
acquisition of Microcosm Communications Limited by Buyer (the "Microcosm
Registration") and hereby offers to include in a registration statement on Form
S-3 all of the Registrable Shares, (ii) within 15 days of the date of the
Agreement, Seller shall advise Buyer in writing of the number of Registrable
Shares, if any, for which registration is requested and shall deliver a
completed Notice and Questionnaire satisfactory to Buyer with respect to certain
information about Seller specifically for use in the registration statement if
any Registrable Shares are to be included therein, and (iii) if any Registrable
Shares are to be included therein, such Microcosm Registration shall

                                    S 10.1-4
<PAGE>   5
otherwise constitute a Piggyback Registration for purposes of this Section 3. If
at any time after giving any such written notice of its intention to effect any
registration of securities and prior to the effective date of the Registration
Statement filed in connection with such registration, Buyer shall determine for
any reason not to register any securities which gave rise to the Piggyback
Registration, Buyer may, in its sole discretion, give written notice of such
determination to Seller and thereupon it shall be relieved of its obligation to
register any Registrable Shares in connection with such registration. If the
offering subject to any notice given pursuant to this Section 3(a) is to be
underwritten, Seller shall sell the Registrable Shares to be included in the
registration to or through the underwriter or underwriters of the securities
being registered upon terms generally comparable to the terms applicable to
others, and if any underwriter or underwriters reasonably determine that the
number of shares included in the Registration Statement is more than can be sold
in an orderly fashion, then the number of shares which Seller and any other
holders of Buyer's Common Stock having piggyback registration rights will be
permitted to include in such registration statement will be reduced pro rata in
proportion to the number of shares proposed to be included in such registration
by Seller and any other holders having piggyback registration rights to an
amount reasonably acceptable to the underwriter or underwriters.

         (b)  Selection of Underwriters. If any Piggyback Registration is an
underwritten offering, Buyer will select the investment banker(s) and manager(s)
that will administer the offering and Buyer and Seller shall enter into a
customary underwriting agreement with such investment banker(s) and manager(s).

         SECTION 4. Registration Procedures.

         (a)  Obligations of Buyer. Whenever Buyer effects the registration of
Registrable Shares under the Securities Act pursuant to Section 2 or Section 3
hereof, Buyer shall:

              (1)  Prepare and file (or cause to be filed) with the SEC a
    Registration Statement on Form S-3 (or any applicable successor form) with
    respect to the applicable Registrable Shares and use its reasonable best
    efforts to cause the Registration Statement to become effective;

              (2)  Prepare and file with the SEC such amendments to the
    Registration Statement and amendments or supplements to the Prospectus
    contained therein as

                                    S 10.1-5
<PAGE>   6
    may be necessary to keep such Registration Statement effective and such
    Registration Statement and Prospectus accurate and complete for the
    Effectiveness Period;

              (3) Furnish to Seller copies of the Registration Statement, any
    preliminary or final Prospectus, any amendment or supplement to any of the
    foregoing and such other documents as Seller may reasonably request in order
    to facilitate the public offering of the Registrable Shares;

              (4) Use its reasonable best efforts to register or qualify the
    Registrable Shares covered by the Registration Statement and to maintain
    such registration or qualification under such state securities or blue sky
    laws as Seller shall reasonably request and do any and all other reasonable
    acts and things that may be necessary or advisable to enable Seller to
    consummate the disposition of the Registrable Shares in such jurisdiction,
    except that Buyer shall not for any purpose be required to execute a general
    consent to service of process or to qualify to do business as a foreign
    corporation in any jurisdiction where it is not so qualified;

              (5) Notify Seller, promptly after it shall receive notice thereof,
    of the date and time when any Registration Statement and each post-effective
    amendment thereto has become effective;

              (6) Notify Seller promptly of any request by the SEC for the
    amending or supplementing of any Registration Statement or Prospectus or for
    additional information;

              (7) Notify Seller, at any time when a Prospectus relating to the
    Registrable Shares is required to be delivered under the Securities Act, of
    any event which would cause any such Prospectus or any other Prospectus as
    then in effect to include an untrue statement of a material fact or omit to
    state any 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 promptly prepare and file with the SEC, and
    promptly notify Seller of the filing of, such amendments or supplements to
    any Registration Statement or Prospectus as may be necessary to correct any
    such statements or omissions;

                                    S 10.1-6
<PAGE>   7
              (8) Notify Seller, promptly after it shall receive notice or
    obtain knowledge thereof, of the issuance of any stop order by the SEC
    suspending the effectiveness of any Registration Statement or the initiation
    or threatening of any proceeding for that purpose and promptly use its
    reasonable best efforts to prevent the issuance of any stop order or to
    obtain its withdrawal if such stop order should be issued;

              (9) Use its reasonable best efforts to list or qualify all
    Registrable Shares covered by any Registration Statement on any securities
    exchange or inter-dealer quotation system on which Buyer's Common Stock is
    then listed or quoted; and

              (10) Otherwise use commercially reasonable efforts to comply with
    all applicable rules and regulations of the SEC, and make available to
    Seller, as soon as reasonably practicable, an earning statement covering the
    period of at least 12 months, beginning with the first full calendar month
    after the effective date of each Registration Statement, which earning
    statement shall satisfy the provisions of Section 11(a) of the Securities
    Act and Rule 158 thereunder.

         (b)  Seller Information. Notwithstanding anything to the contrary
contained herein, Buyer may require that Seller, as a condition to any Demand
Registration or to having Registrable Shares included in any Piggyback
Registration, furnish to Buyer such information regarding Seller and the
contemplated distribution of its Registrable Shares as shall be required to be
included in the applicable Registration Statement, and that such information be
furnished to Buyer in writing and signed by Seller and stated to be specifically
for use in the related Registration Statement, Prospectus or other document
incident thereto.

         (c)  Notice to Discontinue. Seller agrees that, upon receipt of any
notice from Buyer of any event of the kind described in Section 4(a)(7) hereof,
Seller will discontinue disposition of Registrable Securities until Seller
receives copies of the supplemented or amended Prospectus contemplated by
Section 4(a)(7). In addition, if Buyer requests, Seller will deliver to Buyer
(at Buyer's expense) all copies of the Prospectus covering the Registrable
Shares current at the time of receipt of the notice.

         (d)  Notice by Seller. Whenever Seller has requested that any
Registrable Shares be registered pursuant

                                    S 10.1-7
<PAGE>   8
to this Schedule 10.1, Seller shall notify Buyer, at any time when a Prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event (to Seller's knowledge and as to matters concerning
Seller) as a result of which the Prospectus included in the Registration
Statement contains an untrue statement of a material fact or omits to state any
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.

         (e) Suspension of Registration. Notwithstanding anything to the
contrary contained herein, following the effectiveness of a Registration
Statement registering Registrable Shares (whether pursuant to a Demand
Registration or a Piggyback Registration), Buyer may suspend at any time the
availability of such Registration Statement and any related Prospectus upon (i)
the issuance by the SEC of a stop order with respect to such Registration
Statement or the initiation of proceedings with respect to such Registration
Statement under Section 8(d) or 8(e) of the Securities Act, (ii) the occurrence
of any event or the existence of any fact as a result of which (A) any
Registration Statement shall contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, or (B) any Prospectus shall contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, or
(iii) the occurrence or existence of any pending corporate development,
including without limitation any such development that might (A) interfere with
or affect the negotiation or completion of any material transaction or other
material event that is being contemplated by Buyer (whether or not a final
decision has been made to undertake such material transaction at the time the
right to delay is exercised), or (B) involve initial or continuing disclosure
obligations that might not be in the best interest of Buyer's shareowners, that,
in the reasonable discretion of Buyer, makes it appropriate to suspend the
availability of any Registration Statement and the related Prospectus (any
suspension of the availability of a Registration Statement and related
Prospectus upon any event described in any of subsections (i), (ii) and (iii)
above is hereinafter referred to as a "Suspension Period"); provided that the
duration of a Suspension Period under subsections (ii) and (iii) shall not
extend beyond 120 days. Notwithstanding the foregoing, Buyer shall be limited to
no more than two Suspension Periods under subsections (ii) and (iii) above in

                                    S 10.1-8
<PAGE>   9
any rolling 12-month period. Buyer shall endeavor to end any Suspension Period
as promptly as practicable under the circumstances.

         Buyer shall notify Seller in writing of the existence of a Suspension
Period. Upon receipt of any notice from Buyer of a Suspension Period, Seller
shall forthwith discontinue any disposition of Registrable Shares until Seller
(i) is advised in writing by Buyer that the use of the applicable Prospectus may
be resumed, (ii) has received copies of a supplemental or amended Prospectus, if
applicable, and (iii) has received copies of any additional or supplemental
filings which are incorporated or deemed to be incorporated by reference into
such Prospectus.

         SECTION 5. Registration Expenses. With respect to any Demand
Registration effected pursuant to Section 2 hereof (other than a Demand
Registration which is effected as described in Section 2(e) hereof), all fees,
costs and expenses of and incidental to such Demand Registration and the public
offering in connection therewith shall be borne by Seller, and shall be paid by
Seller to Buyer within three days after any request therefor is made by Buyer.
With respect to any Piggyback Registration effected pursuant to Section 3 hereof
or any Demand Registration which is effected as described in Section 2(e)
hereof, all fees, costs and expenses of and incidental to such Piggyback
Registration and the public offering in connection therewith shall be borne by
Seller on a pro rata basis according to the percentage of Seller's Registrable
Shares included in such Piggyback Registration or Demand Registration to the
total number of shares registered in connection therewith, and shall be paid by
Seller to Buyer within three days after any request therefor is made by Buyer.
Notwithstanding the foregoing, Seller will not be obligated to reimburse Buyer
for salary and overhead costs of Buyer's internal personnel or fees for auditing
any Buyer financial statements in connection with any Demand Registration or
Piggyback Registration.

         SECTION 6. Indemnification.

         (a) By Buyer. In the event of any registration of Registrable Shares
under the Securities Act pursuant to this Schedule 10.1, to the fullest extent
permitted by law, Buyer will indemnify Seller and each of its officers,
directors, employees and agents and each person controlling Seller (within the
meaning of Section 15 of the Securities Act) against all expenses, claims,
losses, damages and liabilities arising out of any untrue or allegedly untrue
statement of a material fact contained in any Registration

                                    S 10.1-9

Statement registering Registrable Shares or any Prospectus contained therein or
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, provided, however, that
Buyer will not be liable in any such case to the extent that any such expense,
claim, loss, damage or liability arises out of any untrue or allegedly untrue
statement or omission or alleged omission resulting from information furnished
to Buyer by Seller specifically for use therein or Seller's failure to deliver a
copy of the Registration Statement or Prospectus or any amendments or
supplements thereto after Buyer has been requested to furnish Seller, or has
furnished Seller, with copies of the same.

         (b) By Seller. In the event of any registration of Registrable Shares
under the Securities Act pursuant to this Schedule 10.1, to the fullest extent
permitted by law, Seller will indemnify Buyer, each of its officers, directors,
employees and agents and each person controlling Buyer (within the meaning of
Section 15 of the Securities Act) against all expenses, claims, losses, damages
and liabilities arising out of any untrue or allegedly untrue statement of a
material fact contained in any Registration Statement registering Registrable
Shares or any Prospectus contained therein or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances in which they were
made, not misleading, but only to the extent that such untrue or allegedly
untrue statement or omission or alleged omission resulted from any information
furnished to Buyer by Seller specifically for use therein; provided, however,
that Seller's obligation to indemnify shall be limited to an amount equal to the
net proceeds received by Seller from Registrable Shares sold in connection with
any such registration.

         (c) Each party entitled to indemnification under this Section 6 (the
"Schedule 10.1 Indemnified Party") shall give notice to the party required to
provide indemnification (the "Schedule 10.1 Indemnifying Party") promptly after
such Schedule 10.1 Indemnified Party has actual knowledge of any claim as to
which indemnity may be sought, and shall permit the Schedule 10.1 Indemnifying
Party to assume the defense of any such claim or any litigation resulting
therefrom; provided that the Schedule 10.1 Indemnified Party may participate in
such defense at such party's expense. The failure of any Schedule 10.1
Indemnified Party to give notice as provided herein shall not relieve the
Schedule 10.1 Indemnifying Party of its obligations under this Section 6, except
to the extent that the Schedule 10.1 Indemnifying Party's ability to defend
against such claim or litigation is impaired as a result of such failure to give
notice. No Schedule 10.1 Indemnifying Party shall be liable for any settlement
of any claim or proceeding effected without its written consent. No Schedule
10.1 Indemnifying Party in the defense of any such claim or proceeding shall,
except with the consent of each Schedule 10.1 Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Schedule 10.1 Indemnified Party of a release from all liability in respect to
such claim or proceeding.

         (d) If the indemnification provided for in this Section 6 is held by a
court of competent jurisdiction (by the entry of a final judgment or decree and
the expiration of time to appeal or the denial of the last right of appeal) to
be unavailable to a Schedule 10.1 Indemnified Party with respect to any expense,
claim, loss, damage or liability referred to therein, then the Schedule 10.1
Indemnifying Party, in lieu of indemnifying such Schedule 10.1 Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Schedule 10.1
Indemnified Party as a result of such expense, claim, loss, damage or liability
in such proportion as is appropriate to reflect the relative fault of the
Schedule 10.1 Indemnifying Party on the one hand and of the Schedule 10.1
Indemnified Party on the other in connection with the statements or omissions
that resulted in such expense, claim, loss, damage or liability as well as any
other relevant equitable considerations. The relative fault of the Schedule 10.1
Indemnifying Party and of the Schedule 10.1 Indemnified Party shall be
determined by reference to, among other things, whether the untrue or allegedly
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Schedule 10.1
Indemnifying Party or by the Schedule 10.1 Indemnified Party

and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

         (e) Seller and Buyer agree that it would not be just and equitable if
contribution pursuant this Section 6 were determined by pro rata allocation or
by any other method of allocation that does not take account of the equitable
considerations referred to in Section 6(d). Notwithstanding anything to the
contrary contained herein, Seller will not be required to contribute any amount
pursuant to Section 6(d) in excess of the amount by which the net proceeds
received by Seller from the sale of Registrable Shares pursuant to any
Registration Statement exceeds the amount of any damages Seller has otherwise
been required to pay by reason of such untrue or allegedly untrue statement or
omission or alleged omission. Notwithstanding anything to the contrary contained
herein, no Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) will be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation.

         (f) The indemnification and contribution provided for under this
Schedule 10.1 will survive the sale of Registrable Shares covered by any
Registration Statement under this Schedule 10.1.

         SECTION 7. Not Assignable. Seller may not assign any of the rights
granted under this Schedule 10.1 to any other Person.

         SECTION 8. Delay of Registration. Notwithstanding anything to the
contrary contained herein, Seller shall not have any right to obtain or seek an
injunction restraining or otherwise delaying any registration of securities of
Buyer as the result of any controversy that might arise with respect to the
interpretation or implementation of any provision of this Schedule 10.1.

         SECTION 9. Limitation of Obligations.

         (a) Notwithstanding anything to the contrary contained herein, Buyer
shall have no obligations to register or maintain any Registration Statement
covering Registrable Shares (i) if all Registrable Shares have been registered
and sold pursuant to a Registration Statement effected pursuant to this Schedule
10.1 or (ii) if all Registrable Shares held by Seller may be sold within a three
month period under Rule 144.

                  (b) Notwithstanding anything to the contrary contained herein,
neither Seller nor Buyer will have any liability under this Schedule 10.1
(whether or not related to any breach or alleged breach hereof) or in connection
with any Demand Registration or Piggyback Registration for any consequential,
special, incidental or punitive damages or lost profits.
