2.    Piggy Back Registration Rights.

      (a) If at any time during the period commencing on the Closing Date (as
defined in the Merger Agreement) and ending on the earliest to occur of the
following: (i) all Registrable Securities covered by a Registration Statement
have been sold under such Registration Statement, or (ii) a subsequent
Registration Statement covering all of the Registrable Securities has been
declared effective under the Securities Act, or (iii) Holders no longer hold any
Registrable Securities or (iv) all Registrable Securities held by Holders may be
sold in compliance with Rule 144, the Company proposes to register any of its
securities under the Securities Act on any form for the registration of
securities under the Securities Act, whether or not for its own account (other
than by a registration statement on Form S-4 or Form S-8 or other form which
does not include substantially the same information as would be required in a
form for the general registration of securities or would not be available for
the Registrable Securities) (a "Piggy Back Registration"), it shall as
expeditiously as possible give written notice to the Holders of its intention to
do so and of the Holders' rights under Sections 2 through 4. (Such rights are
referred to hereinafter as "Piggy Back Registration Rights.") Upon the written
request of any of such Holders made within five (5) business days after receipt
of any such notice (which request shall specify the Registrable Securities
intended to be disposed of by each such Holder), the Company shall use its best
efforts to (i) include in the Registration Statement (and in any



                                        3
<PAGE>   5
underwriting relating thereto) all of the Registrable Securities with respect to
which the Company has received such requests and (ii) have such Registration
Statement declared effective by the Commission and maintain the effectiveness
thereof for the period necessary for the Holders to effect the proposed sale or
other disposition (but in no event for a period greater than 90 days).

      (b) If at any time after giving written notice of its intention to
register any securities in a Piggy Back Registration but prior to the effective
date of the related Registration Statement, the Company shall determine for any
reason not to register such securities, the Company shall give written notice of
such determination to the Holders and thereupon shall be relieved of its
obligation to register any Registrable Securities in connection with such Piggy
Back Registration; provided, however, that the Company shall concurrently give a
similar notice to all other holders of the Company's securities selling such
securities under such Registration Statement pursuant to piggy back registration
rights.

      (c) If a Piggy Back Registration involves an offering by or through one or
more underwriters, then the Holders, provided they have requested to have
Registrable Securities included in the Company's Registration Statement, shall
agree to sell their Registrable Securities to the underwriters selected by the
Company on the same terms and conditions as apply to other selling shareholders
and enter into an underwriting agreement with such underwriters containing
customary selling shareholder representations and warranties.

      (d) The Registration Statement filed in accordance with this Section may
include other securities of the Company with respect to which registration
rights have been granted, and may include securities of the Company being sold
for the account of the Company.

      (e) If a Piggy Back Registration involves an offering by or through one or
more underwriters, the Company shall not be required to include Registrable
Securities therein if and to the extent the underwriter managing the offering
reasonably believes in good faith and advises the Company in writing (which in
turn so advises the Holders in writing) that such inclusion would adversely
affect such offering as a result of marketing factors. The number of Registrable
Securities that may be included, if any, following such underwriting cutback
shall be allocated among the exercising Holders and all other holders selling
securities under such Registration Statement pursuant to piggy back registration
rights on a pro rata basis according to the number of Registrable Securities
requested to be included in such Piggy Back Registration.

3.    Registration Procedures

      In connection with the Company's registration obligation hereunder, the
Company shall effect such registration on the appropriate form available for the
sale of the Restricted Securities to permit the sale of the Restricted
Securities in accordance with the method or methods of disposition thereof
specified by the Holders, and pursuant thereto the Company shall as
expeditiously as reasonably possible:



                                        4
<PAGE>   6
      (a) No fewer than five (5) Business Days prior to the initial filing of
the Registration Statement or Prospectus and, if practical, no fewer than two
(2) Business Days prior to the filing of any amendment or supplement thereto
(other than any document that would be incorporated or deemed to be incorporated
therein by reference), furnish to the Holders, copies of all such documents
proposed to be filed, which documents, if practical (other than those
incorporated or deemed to be incorporated by reference) will be subject to the
review of such Holders. The Company shall not file such Registration Statement
or related Prospectus or any amendments or supplements thereto to which the
Holders covered thereby shall reasonably object on a timely basis;

      (b) Prepare and file with the Commission such amendments, including
post-effective amendments, to each Registration Statement as may be necessary to
keep such Registration Statement continuously effective for the Effectiveness
Period; cause the related Prospectus to be supplemented by any required
Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424
under the Securities Act; and comply with the provisions of the Securities Act
and the Exchange 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 selling Holders thereof contemplated
hereby and set forth in such Registration Statement as so amended or in such
Prospectus as so supplemented.

      (c) Notify the Holders promptly (and in the case of an event specified by
clause (i)(A) of this paragraph, if practical, in no event fewer than two (2)
Business Days prior to such filing), and (if requested by any such Person),
confirm such notice in writing, (i)(A) when a Prospectus or any Prospectus
Supplement or post-effective amendment is proposed to be filed, and (B) with
respect to the Registration Statement or any post-effective amendment, when the
same has become effective, (ii) of any request by the Commission or any other
federal or state governmental authority for amendments or supplements to the
Registration Statement or related Prospectus or for additional information,
(iii) of the issuance by the Commission, any state securities commission, any
other governmental agency or any court of any stop order, order or injunction
suspending or enjoining the use or the effectiveness of the Registration
Statement or the initiation of any proceedings for that purpose, (iv) of the
receipt by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Restricted
Securities for sale in any jurisdiction, or the initiation or threat of any
proceeding for such purpose, and (v) of the happening of any event that makes
any statement made in such Registration Statement or related Prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue
in any material respect or that requires the making of any changes in such
Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, not misleading, and that in
the case of the Prospectus, it will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading;



                                        5
<PAGE>   7
      (d) Use its reasonable best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of any order enjoining or suspending the use or
effectiveness of the Registration Statement or the lifting of any suspension of
the qualification (or exemption from qualification) of any of the Restricted
Securities for sale in any jurisdiction, at the earliest reasonable practicable
moment;

      (e) If requested by the Holders, (i) promptly incorporate in a Prospectus
supplement or post-effective amendment such information as the Holders indicate
relates to them or otherwise reasonably request be included therein, and (ii)
make all required filings of such Prospectus supplement or such post-effective
amendment as soon as practicable after the Company has received notification of
the matters to be incorporated in such Prospectus supplement or post-effective
amendment; provided, however, that the Company shall not be required to take any
action pursuant to this Section 3(e) that would, in the opinion of counsel for
the Company, violate applicable law;

      (f) Furnish to each Holder without charge, at least one conformed copy of
the Registration Statement and each amendment thereto, including financial
statements (but excluding schedules and all documents incorporated or deemed to
be incorporated therein by reference);

      (g) Deliver to each Holder as many copies of the Prospectus or
Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons reasonably request; and the Company hereby
consents to the use of such Prospectus and each amendment or supplement thereto
by each of the Holders in connection with the offering and sale of the
Restricted Securities covered by such Prospectus and any amendment or supplement
thereto;

      (h) Prior to any public offering of the Restricted Securities, use its
reasonable best efforts to register or qualify or cooperate with the Holders in
connection with the registration or qualification (or exemption from such
registration or qualification) of such Restricted Securities for offer and sale
under the securities or "Blue Sky" laws of such jurisdictions within the United
States as any Holder reasonably requests in writing and to cause the offering of
the Restricted Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the
United States, except as may be required as a consequence of the selling
Holder's business (in which case the Company will cooperate in all reasonable
respects with the filing of such Registration Statement therewith and granting
of approvals thereby), as may be necessary to enable the selling Holders to
consummate the disposition of such Restricted Securities; keep each such
registration or qualification (or exemption therefrom) or approval effective
during the period such Registration Statement is required to be kept effective
and do any and all other acts necessary or advisable to enable the disposition
in such jurisdictions of the Restricted Securities covered by the Registration
Statement; provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so qualified
or to take any action that would



                                        6
<PAGE>   8
subject it to general service of process in any such jurisdiction where it is
not then so subject or subject the Company to any tax in any such jurisdiction
where it is not then so subject;

      (i) In connection with any sale or transfer of the Restricted Securities
that will result in such securities no longer being Restricted Securities,
cooperate with the Holders to facilitate the timely preparation and delivery of
certificates representing the Restricted Securities to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depository Trust Company and to enable such
Restricted Securities to be in such denominations and registered in such names
as the Holders may request at least two (2) Business Days prior to any sale of
the Restricted Securities;

      (j) Upon the occurrence of any event contemplated by Section 3(c)(v)
hereof, as promptly as practicable, prepare a supplement or amendment,
including, if appropriate, a post-effective amendment, to the Registration
Statement or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required
document so that, as thereafter delivered, such Prospectus will not contain an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading;

      (k) Comply with applicable rules and regulations of the Commission and
make generally available to its security holders earning statements satisfying
the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder
(or any similar rule promulgated under the Securities Act), no later than 45
days after the end of any 12-month period (or 90 days after the end of any
12-month period if such period is a fiscal year) commencing on the first day of
the first fiscal quarter after the effective date of the Registration Statement,
which statement shall cover said period, consistent with the requirements of
Rule 158;

      (l) List all Common Stock covered by such Registration Statement on the
exchange or system, if any, on which the Common Stock of the Company is then
listed;

      (m) If necessary in connection with a disposition of Registrable
Securities, make available for inspection, at the offices where normally kept
during reasonable business hours, by a representative of any Holder and any
attorney or accountant retained by such Holder, financial and other records,
pertinent corporate documents and properties of the Company and its subsidiaries
as they may reasonably request, and cause the officers, directors and employees
of the Company and its subsidiaries to supply all information reasonably
requested by any such representative, attorney or accountant in connection with
such disposition, provided, that all records, information or documents made
available for inspection by the Company shall be deemed to be confidential and
at the time of delivery of such records, information or documents shall be kept
confidential by such Persons, and such Persons shall so agree in writing, unless
(i) such records, information or documents are in the public domain or otherwise
publicly available, (ii) disclosure of such records, information or documents is
required by court or administrative



                                        7
<PAGE>   9
order or is necessary to respond to inquiries of regulatory authorities or (iii)
disclosure of such records, information or documents is otherwise required by
law (including, without limitation, pursuant to the requirements of the
Securities Act; and.

      (n) Take all such other actions in connection therewith in order to
expedite or facilitate the disposition of such Registrable Securities.

      The Company may require each seller of the Restricted Securities as to
which any registration is being effected to: (i) furnish to the Company such
information regarding the distribution of such Restricted Securities as is
required by law to be disclosed in the Registration Statement and (ii) provide
to the Company a signed writing accepting and acknowledging its rights and
obligations hereunder. The Company may exclude from such registration the
Restricted Securities of any holder of Restricted Securities who unreasonably
fails to furnish such information or signed writing at least five (5) Business
Days prior to the effective date of such Registration Statement.

      Each Holder agrees by acquisition of the Restricted Securities that, upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), or 3(c)(v) hereof, such
Holder will forthwith discontinue disposition of such Restricted Securities
covered by such Registration Statement or Prospectus until such Holder's receipt
of the copies of the supplemented or amended Prospectus contemplated by Section
3(i) hereof, or until it is advised in writing (the "Advice") by the Company
that the use of the applicable Prospectus may be resumed, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus.

      The registration rights of the Holders pursuant to this Agreement and the
ability to offer and sell Restricted Securities pursuant to the Registration
Statement are subject to the conditions and limitations contained in this
paragraph, and each Holder will be deemed to have agreed with the Company that
if the Board of Directors of the Company determines in its good faith judgment,
as evidenced by a resolution of the Board of Directors, that the use of any
Prospectus would require the disclosure of material information that the Company
has a bona fide business purpose for preserving as confidential or the
disclosure of which would impede the Company's ability to consummate a
significant transaction, and that the Company is not otherwise required by
applicable securities laws or regulations to disclose, upon written notice of
such determination by the Company, the rights of the Holders to offer, sell or
distribute any Restricted Securities pursuant to the Registration Statement or
to require the Company to take action with respect to the registration or sale
of any Restricted Securities pursuant to the Registration Statement shall be
suspended until the date upon which the Company notifies the Holders and all
other holders selling securities under such Registration Statement in writing
that suspension of such rights for the grounds set forth in this paragraph is no
longer necessary subject to the limits set forth herein, and the Company agrees
to give such notice as promptly as practicable following the date that such
suspension of rights is no longer necessary.

4.    Registration Expenses

      All fees and expenses incident to the performance of or compliance with
this Agreement by the Company shall be borne by it whether or not the
Registration Statement is filed or becomes effective and whether or not any
securities are issued or sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (a) all registration and filing fees (including, without limitation,
fees and expenses in compliance with securities or "Blue Sky" laws), (b)
printing expenses (including, without limitation, expenses of printing
Prospectuses), (c) messenger, telephone and delivery expenses, (d) fees and

expense of any annual audit, and the fees and expenses incurred in connection
with the listing of the securities to be registered on any securities exchange.
Notwithstanding the foregoing or anything in this Agreement to the contrary,
each Holder shall pay all underwriting discounts and commissions of any
underwriters or broker-dealers with respect to any Restricted Securities sold by
it.

5.    Indemnification

      (a) The Company (as an "Indemnifying Person") agrees to indemnify and hold
harmless each Holder and his representatives and agents (an "Indemnified
Person"), from and against any and all losses, claims, damages, liabilities and
judgments caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement, Prospectus or form of
Prospectus or in any amendment or supplement thereto or in any preliminary
Prospectus, or caused by (i) any omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the case of any Prospectus or form of Prospectus or
supplement thereto, in the light of the circumstances under which they were
made, not misleading, except insofar as such losses, claims, damages,
liabilities or judgments are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any
Indemnified Person furnished to the Company in writing by or on behalf of such
Indemnified Person for the specific purpose of inclusion in the Registration
Statement or (ii) any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law; provided that the foregoing indemnity with respect to any
preliminary Prospectus shall not inure to the benefit of any Indemnified Person
from whom the Person asserting such losses, claims, damages, liabilities and
judgments purchased securities if such untrue statement or omission or alleged
untrue statement or omission made in such preliminary Prospectus is eliminated
or remedied in the Prospectus and a copy of the Prospectus shall not have been
furnished to such Person in a timely manner provided such failure is not as a
result of an action or inaction on the part of the Indemnifying Person.



                                        9
<PAGE>   11
      (b) In case any action shall be brought against any Indemnified Person,
based upon the Registration Statement or any such Prospectus or any amendment or
supplement thereto and with respect to which indemnity may be sought against the
Company, such Indemnified Person shall promptly notify the Company in writing
and the Company shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Person and payment of all
fees and expenses. Any Indemnified Person shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Person, unless (i) the employment of such counsel shall have been
specifically authorized in writing by the Company, (ii) the Company shall have
failed to assume the defense and employ counsel for the Indemnified Parties or
(iii) the named parties to any such action (including any impleaded parties)
include both such Indemnified Person and the Company and such Indemnified Person
shall have been advised by counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
Company (in which case the Company shall not have the right to assume the
defense of such action on behalf of such Indemnified Person), provided, however,
that the Company shall not, in connection with any such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all such Indemnified Persons, which firm shall be designated in
writing by such Indemnified Persons; and provided, however, that all such fees
and expenses shall be reimbursed as they are incurred. The Company shall not be
liable for any settlement of any such action effected without its written
consent but if settled with the written consent of the Company, the Company
agrees to indemnify and hold harmless any Indemnified Person from and against
any loss or liability by reason of such settlement. No Indemnifying Person
shall, without the prior written consent of the Indemnified Person, effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Person is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Person, unless such settlement includes an
unconditional release of such Indemnified Person from all liability on claims
that are the subject matter of such proceeding.

      (c) In connection with the Registration Statement, each Holder
participating in such Registration Statement agrees, severally and not jointly,
to indemnify and hold harmless the Company, its directors, its officers and any
Person controlling the Company within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to each Indemnified Person but only with
reference to information relating to such Indemnified Person furnished in
writing by or on behalf of such Indemnified Person for the specific purpose of
inclusion in the Registration Statement. In case any action shall be brought
against the Company, any of its directors, any such officer or any Person
controlling the Company based on such Registration Statement and in respect of
which indemnity may be sought against any Indemnified Person, the Indemnified
Person shall have the rights and duties given to the Company (except that if the
Company shall have assumed the defense thereof, such Indemnified Person shall
not be required to do so, but may employ separate counsel therein and
participate in the defense thereof but the fees and expenses of such counsel



                                       10
<PAGE>   12
shall be at the expense of such Indemnified Person), and the Company, its
directors, any such officers and any Person controlling the Company shall have
the rights and duties specified for Indemnified Persons in Section 5(b) hereof.

      (d) If the indemnification provided for in this Section 5 is unavailable
to an Indemnified Person in respect of any losses, claims, damages, liabilities
or judgments referred to therein, then each indemnifying party, in lieu of
indemnifying such Indemnified Person, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claim, damages,
liabilities and judgments in such proportion as is appropriate to reflect the
relative fault of the Company and each such Indemnified Person in connection
with the statements, omissions or violations which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative fault of the Company and each such
Indemnified Person 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 Company
or such Indemnified Person and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.

      The Company and the Holders agree that it would not be just and equitable
if contribution pursuant to this Section 5(d) were determined by pro rata
allocation (even if the Indemnified Persons were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such Indemnified
Person in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 5, no Indemnified Person shall be
required to contribute any amount in excess of the amount by which the total net
proceeds received by it in connection with the sale of the Restricted Securities
pursuant to this Agreement exceeds the amount of any damages which such
Indemnified Person has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. The Indemnified Persons'
obligations to contribute pursuant to this Section 5(d) are several in
proportion to the respective amount of Restricted Securities included in any
such Registration Statement by each Indemnified Person and not joint.

6.    Rule 144

      The Company shall use its reasonable best efforts to file the reports
required to be filed by it under the Securities Act and the Exchange Act in a
timely manner and, if at any time it is not required to file such reports but in
the past had been required to or did file such reports, it



                                       11

will, upon the request of any Holder, make available other information as
required by, and so long as necessary to permit, sales of its Restricted
Securities pursuant to Rule 144.

7.    Miscellaneous

      (a) Remedies. In the event of a breach by the Company, or by a Holder of
