          specified in such request; provided, that the Company shall not be
          obligated to take any action to effect any such registration,
          qualification or compliance pursuant to Section 2.1; (i) in any
          particular jurisdiction in which the Company would be required to
          register as a dealer or to cause any officer or employee of the
          Company to register as a salesman in effecting such registration,
          qualification or compliance, or (ii) after the Company has effected
          three such registrations requested by such shareholder or group of
          shareholders pursuant to this Section 2.1.1 and such registrations
          have been declared or ordered effective; provided, that the
          shareholder or group of shareholders in question shall have been

underwriters to an amount less than 75% of the shares of Registrable Securities
it or they desired to sell, then the ending date of the period shall be reduced
to 90 days, (ii) during which the Company is in possession of material
information concerning it or its business and affairs and which it is not
otherwise required by law to disclose publicly, the public disclosure of which

Shareholders, as the case may be, would propose to employ in connection with the
public offering proposed to be made pursuant to the registration requested;
provided, that, if the Company reasonably objects to any managing underwriter or
underwriters proposed by MascoTech or the Tsuha Shareholders, as the case may
be, MascoTech or the Tsuha Shareholders, as the case may be, shall propose
another managing underwriter or underwriters. If the sale proposed by MascoTech
or the Tsuha Shareholders, as the case may be, is to be effected pursuant to an
underwritten public offering, the right of MascoTech or the Tsuha Shareholders,

Shareholders', as the case may be, Registrable Securities in the underwriting to
the extent requested as otherwise provided herein. The Company shall enter into
an underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting in the manner set forth above and on such
customary terms of such underwriter as the Company and MascoTech or the Tsuha
Shareholders, as the case may be, shall agree. In order to facilitate the
process of registering and selling such securities, the terms thereof are set
forth in this Article II. Notwithstanding any other provisions of Section 2.1,
if the managing underwriter advises MascoTech or the Tsuha Shareholders, as the
case may be, in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
limited as advised by the managing underwriter and no Registrable Securities
excluded from the underwriting by reason of the underwriter's marketing
limitation shall be included in such registration. If MascoTech or the Tsuha
Shareholders, as the case may be, disapprove of the terms of the underwriting,
it or they may elect to withdraw therefrom by written notice to the Company and
the managing underwriter. The Registrable Securities so withdrawn shall also be
withdrawn from registration.

2.2       COMPANY REGISTRATION

2.2.1     RIGHT TO INCLUSION. If at any time or from time to time, the Company
shall determine to register any of its equity securities in an underwritten
offering, either for its own account or the account of any shareholder, other
than (a) a registration relating solely to employee benefit plans, (b) a
registered offering primarily to employees of the Company and its subsidiaries,
(c) a registration relating solely to a transaction described in Rule 145 under
the Securities Act, (d) a transaction relating solely to an exchange pursuant to
Section 3(a)(9) under the Securities Act, (e) a transaction relating solely to
an acquisition of assets or property for securities, or (f) a registration on
any form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of
Registrable Securities by MascoTech or the Tsuha Shareholders of Registrable
Securities, then the Company will:

          (i)  promptly give to MascoTech and to the Tsuha Shareholders written
               notice thereof; and

          (ii) include in such registration (and any related qualification under
               blue sky laws or other compliance), and in any underwriting
               involved therein, all (or such portion thereof as the Company and
               the managing underwriter of the registered offering shall, in
               their discretion, determine) of the Registrable Securities
               specified in any written request by MascoTech or the Tsuha
               Shareholders received by the Company within 30 days after such
               written notice is given on such of the customary terms of such
               inclusion as the Company and MascoTech or the Tsuha Shareholders,
               as the case may be, shall agree.

2.2.2     UNDERWRITING, The rights of MascoTech and of the Tsuha Shareholders to
registration pursuant to section 2.2 shall be conditioned upon MascoTech's or
the Tsuha Shareholders', as the case may be, participation in the underwriting
and the inclusion of such of MascoTech's or the Tsuha Shareholders', as the case
may be, Registrable Securities in the underwriting on such


                                       4
<PAGE>   5

customary terms of the underwriter as the Company and MascoTech or the Tsuha
Shareholders, as the case may be, shall agree. In order to facilitate the
process of registering and selling equity shares of the Company the terms
thereof are set forth in this Article II., MascoTech and the Tsuha Shareholders,
as the case may be, shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for such underwriting by the
Company.

Notwithstanding any other provisions of Section 2.2, if the managing underwriter
determines that marketing factors require a limitation of the number of shares
to be underwritten, the underwriter and the Company may limit or exclude
entirely the Registrable Securities to be included in any registration and
underwriting. In such event, the Company shall so advise MascoTech and the Tsuha
Shareholders.

No Registrable Securities excluded from the underwriting by reason of the
managing underwriter's marketing limitation shall be included in such
registration. If MascoTech or the Tsuha Shareholders disapprove of the terms of
the underwriting, it or they may elect to withdraw therefrom by written notice
to the Company and the managing underwriter. The Registrable Securities so
withdrawn shall also be withdrawn from registration.

Company and fees and expenses of accountants incidental to or required by such

               registration proceeding begun pursuant to Section 2.1, the
               request for which has been subsequently withdrawn by MascoTech or
               the Tsuha Shareholders, as the case may be, and in such case,
               such expenses shall be borne by MascoTech or the Tsuha
               Shareholders, as the case may be; and

          (b)  The Company shall not be required to pay stock transfer taxes,
               underwriters' fees, discounts or commissions relating to
               Registrable Securities sold, or the fees and disbursements of
               counsel for MascoTech or the Tsuha Shareholders.

               thereto as MascoTech or the Tsuha Shareholders from time to time

2.5       RELATED REGISTRATION MATTERS. The Company shall enter into an
underwriting agreement in connection with any registration subject to the
provisions of Section 2.1 and 2.2 hereof, which agreement shall contain such
terms, provisions and agreements as are customary and appropriate for such
registration. In connection with the registration, to the extent not provided in

               Section 11 (a) of the Securities Act and covering a period of at
               least 12 consecutive months beginning after the effective date of
               the registration statement.

2.6       INDEMNIFICATION AND CONTRIBUTION. In connection with any registration
of Registrable Securities pursuant to Article II the Company and MascoTech or
the Tsuha Shareholders, as the case may be (and the underwriters, if any), will
enter into an agreement (which shall be the underwriting agreement in the case
of an underwritten offering) containing mutual indemnification and contribution
rights and procedures in form and substance (i) satisfactory to the Company and
to MascoTech and/or the Tsuha Shareholders and (ii) customary for underwritten
secondary public securities offerings; provided, however, that the liability of
each seller of Registrable Securities pursuant to such indemnification and
contribution provisions shall be limited to the net proceeds (after all expenses
are paid by such seller) from the disposition of the Registrable Securities
disposed of by such seller pursuant to such registration.


2.7       INFORMATION BY SHAREHOLDERS. MascoTech and/or the Tsuha Shareholders
shall furnish to the Company such information regarding it and the distribution

such information as is necessary in order to establish that such Transfer may be
made without registration under the Securities Act, and (b) (if the Transfer is
not made in compliance with Rule 144 thereunder) at the expense of the

satisfactory in form and substance to the Company to the effect that such
Transfer may be made without registration under the Securities Act; provided,
that nothing contained in this Section 2.8 shall relieve the Company from
complying with any request for registration, qualification or compliance made
pursuant to the other provisions of Article II.

2.9       RULE 144 REPORTING. With a view to making available to MascoTech and
the Tsuha Shareholders the benefits of certain rules and regulations of the SEC
which may permit the sale of the Registrable Securities to the public without

          (a) SEC REPORTS. File with the SEC in a timely manner all reports and
other documents thereafter required of the Company if the Company becomes

Act; and

          (b) OTHER INFORMATION. Furnish to MascoTech and to any Tsuha
Shareholder forthwith upon its request (i) a written statement by the Company as

becomes subject to the reporting requirements of Section 13 or 15 (d) of the
Exchange Act), (ii) a copy of the most recent annual or quarterly report of the

register Registrable Securities granted by the Company under Section 2.1 and the
right to participate in Company registrations under Section 2.2 may be assigned
by MascoTech or the Tsuha Shareholders, as the case may be, to a transferee or
assignee of all (but not less than all) of MascoTech's or such Tsuha
Shareholders' Registrable Securities, unless such transferee or assignee
acquires such Registrable Securities through a transaction, or chain of
transactions involving a public offering or a sale effected pursuant to Rule 144
under the Securities Act; provided that the Company is given written notice by
the transferor at the time of or within 10 days after said Transfer, setting
forth the name and address of said transferee or assignee and identifying the
Registrable Securities with respect to which such registration rights are being
assigned.

out of or relating to this Agreement. MascoTech and the Tsuha Shareholders each

proceeding brought in such a court has been brought in an inconvenient forum.

binding upon it and may be enforced in the courts of the State of Michigan and
the United States of America (or any other courts to the jurisdiction of which
it is or may be subject) by a suit upon such judgment, provided that lawful
service of process is effected upon it at the address for which notices are to
be given or served to it pursuant to Section 3.4 of this Agreement. Nothing in
this Section 3.6 shall affect the right of the Company to serve process in any
manner permitted by law or limit the right of the Company to bring proceedings

stricken from this Agreement to the extent required for the purposes of validity
and enforcement thereof.

                                    EXHIBIT A

                               REGISTRATION RIGHTS

1.   Definitions.  For purposes of this Exhibit A, the following terms shall
have the following meanings:

"Common Stock" means the Company's common stock, no par value per share.

"Exchange Act" means the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder.

"Holder" means collectively, the Holder of the Warrant as set forth in the
Warrant Certificate(s) and any transferee of the Warrant (or any part thereof)
permitted pursuant to the terms of the Warrant.

"Person" means an individual, partnership, corporation, limited liability
company, trust or other entity, or a government or agency or political
subdivision thereof.

"Prospectus" means the prospectus included in any Registration Statement at the
time the same becomes effective, as amended or supplemented by any prospectus
supplement, including post-effective amendments and all material incorporated by
reference in the prospectus.

"Registrable Securities" means the Shares; provided, however, that a Share shall
be a Registrable Security only for so long as the Share continues to be a
Restricted Security. For purposes of this Exhibit A, each Share shall be a
Restricted Security at the date of this Exhibit A. A Share shall cease to be a
Restricted Security on the earliest of the following dates: (i) the date the
Company has effectively registered the Share under the Securities Act and the
Holder has disposed of the Share in accordance with the Registration Statement
covering the Share, or (ii) the date the Holder shall be eligible to sell (in
one transaction) all of the Registrable Securities held by the Holder to the
public pursuant to Rule 144 (or any similar provisions then in force) under the
Securities Act, or (iii) the date the Holder has otherwise transferred the
Share.

"Registration Statement" means any registration statement of the Company which
covers any of the Registrable Securities pursuant to the provisions of this
Exhibit A, including all pre-effective amendments and post-effective amendments
thereto, the Prospectus and supplements thereto, all exhibits and all material
incorporated by reference in the registration statement.

"SEC" means the Securities and Exchange Commission.

"Securities Act" means the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder.

2A. Shelf Registration. Within 60 days after the Holder requests the Company to
file a Registration Statement with respect to the Registrable Securities
(provided that the Holder shall

                                       12
<PAGE>   13

not be entitled to make such a request prior to the date the Company becomes
eligible to file a Registration Statement (with respect to the sale of the
Shares by the Holder) on Form S-3 under the Securities Act), the Company shall
prepare and file a Registration Statement providing for the sale of the
Registrable Securities by the Holder pursuant to Rule 415 of the Securities Act
and/or any similar rule that may be adopted by the SEC; provided, however, that
the Holder shall not sell, transfer, pledge or otherwise dispose of any
Registrable Securities while such Registration Statement remains effective,
except during the ten (10) business days immediately following the second
business day following the release by the Company to the public of quarterly or
annual earnings. Notwithstanding the foregoing, if the Company shall furnish to
the Holder a certificate signed by the President of the Company stating that, in
the good faith judgment of the President of the Company, the Company is in
receipt of material, undisclosed information, the disclosure of which would be
detrimental to the Company, then the Holder shall not sell, transfer, pledge or
otherwise dispose of any Registrable Securities for the period or periods
specified in such certificate; provided, however, that the Holder shall not be
so restricted with respect to such sales, transfers, pledges or other
dispositions pursuant to this sentence or the next succeeding sentence for more
than an aggregate of ninety (90) days in any fiscal year of the Company. If at
any time after the Company files a Registration Statement hereunder the Company
decides to make a public offering of securities through one or more
underwriters, and an underwriter selected by the Company to manage such proposed
underwriting advises the Company that it believes that such underwritten
offering could be adversely affected by the concurrent registered offering of
Registrable Securities pursuant hereto, then the Holder shall not sell,
transfer, pledge or otherwise dispose of any Registrable Securities at the
request of the Company during such public offering of securities; provided
further, that the aggregate period of any such restriction, when taken together
with the restriction imposed by the Company pursuant to a certificate signed by
the President of the Company pursuant to the previous sentence, shall not exceed
ninety (90) days in any fiscal year of the Company.

2B. Incidental Registration. If the Company at any time (other than pursuant to
Section 2A hereof) proposes to register its Capital Stock under the Securities
Act for sale to the public, whether for its own account or for the account of
other security holders or both (except with respect to registration statements
on Forms S-4 or S-8 or another form not available for registering Common Stock
for sale to the public) each such time it will give at least 20 days' prior
written notice to the Holder of its intention to do so ("Notice of Incidental
Registration"). If at the time of such notice there does not exist an effective
registration statement pursuant to Section 2A with respect to Registrable
Securities held by Holder (or if pursuant to Section 2A the Company is not
permitted to sell its Registrable Securities for any reason pursuant to the
Shelf Registration), upon the written request of the Holder given within 10 days
after receipt of any Notice of Incidental Registration (which request shall
state the intended method of disposition thereof), the Company will use its best
efforts to cause the Registrable Securities as to which registration shall have
been so requested to be included in the securities to be covered by the
registration statement proposed to be filed by the Company, all to the extent
requisite to permit the sale or other disposition by the Holder (in accordance
with its written request) of such Registrable Securities so registered. The
amount of Registrable Securities to be included in such an underwriting may be
reduced if and only to the extent that the managing underwriter shall be of the
opinion that such inclusion would adversely affect the price of the Registrable
Securities to be

                                       13
<PAGE>   14

sold therein; provided, further, however, that, in an initial public offering,
the Company shall have the first priority to sell shares of Common Stock in such
offering and the number of shares requested to be included in such public
offering by the Holder shall be reduced pro rata based on the number of shares
owned by the Holder on the date notice is given by the Company pursuant to this
Section 2B.

3.   Registration Procedures. In connection with the Company's registration
obligations pursuant to Sections 2A and 2B of this Exhibit A, the Company shall
use its best efforts to effect the registration of the Registrable Securities in
accordance with the method of distribution described on the attached Schedule 1
and, pursuant thereto, the Company shall as reasonably expeditiously as
possible:

(a)  prepare and file with the SEC a Registration Statement within 60 days after
the initial request from the Holder to register such Registrable Securities and
use its best efforts to cause such Registration Statement to become effective
within 90 days after the initial request from the Holder to register such
Registrable Securities;

(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 continuously effective for a
period expiring on the earlier of (i) the date on which all of the Registrable
Securities covered by the Registration Statement have been sold pursuant thereto
or (ii) the date on which all Registrable Securities are eligible for sale
pursuant to Rule 144 under the Securities Act;

(c)  furnish to the Holder, without charge, at least one signed copy of the
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules, all documents incorporated by reference
therein and all exhibits (including those incorporated by reference);

(d)  deliver to the Holder, without charge, as many copies of the Prospectus
(including each preliminary prospectus) and any amendment or supplement thereto
as it may reasonably request, but only while the Company is required to cause
the Registration Statement to remain effective;

(e)  use its best efforts to register or qualify such Registrable Securities for
offer and sale under the securities or blue sky laws of such U. S. States or
possessions as the Holder may reasonably request (the "Blue Sky Laws") and do
any and all other acts or things necessary or advisable to enable the Holder to
consummate the disposition in such jurisdictions of Registrable Securities owned
by the Holder; provided, however, that in no event shall the Company be
obligated to qualify generally to do business in any jurisdiction where it is
not now qualified or to take any action which would subject it to the service of
process in suits other than those arising out of the offer or sale of the
securities covered by such Registration Statement in any jurisdictions where it
is not now so subject or subject itself to taxation in any jurisdiction where it
would not otherwise be subject;

(f)  cooperate with the Holder to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold, free of any and
all restrictive legends, which

                                       14
<PAGE>   15

     certificates shall be in such denominations and registered in such names as
     the Holder may request;

(g)  use its best efforts to cause all Registrable Securities covered by the
Registration Statement to be listed on the Nasdaq Stock Market ("Nasdaq") (or
any other market on which the Common Stock is then listed);

(h)  promptly notify the Holder 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
the Holder, except as provided in Section 2(a), the Company shall prepare a
supplement or amendment to such Prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such Prospectus shall not contain
any untrue statement of a material fact or omit to state any fact necessary to
make the statements therein not misleading.

(i)  advise the Holder, promptly after it shall receive notice or obtain
knowledge thereof, of the issuance of any stop order by the SEC suspending the
effectiveness of such Registration Statement or the initiation of any proceeding
for such purpose and promptly use all reasonable efforts to prevent the issuance
of any stop order or to obtain its withdrawal if such stop order should be
issued;

(j)  furnish to the Holder at the time of the disposition of such Registrable
Securities by the Holder a signed copy of an opinion of counsel for the Company
as to such matters as such Holder may reasonably request and substantially to
the effect that, a registration statement covering such Registrable Securities
has been filed with the Commission under the Securities Act and has been made
effective by order of the Commission; said registration statement and the
prospectus contained therein comply as to form in all material respects with the
requirements of the Securities Act and, based upon such investigation and
inquiry as said counsel deems necessary or appropriate, nothing has come to said
counsel's attention that would cause it to believe that either said registration
statement or said prospectus contains an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein (in the case of said prospectus, in the light of the
circumstances under which they were made) not misleading; said counsel knows of
no legal or governmental proceedings required to be described in said prospectus
that are not described as required, or of any contract or documents of a
character required to be described in said registration statement or said
prospectus or to be filed as an exhibit to said registration statement or to be
incorporated by reference therein that is not described and filed as required;
no stop order has been issued by the Commission suspending the effectiveness of
such registration statement and that, to the best of such counsel's knowledge,
no proceedings for the issuance of such a stop order are threatened or
contemplated; and the applicable provisions of the securities or blue sky laws
of each state in which the Company shall be required, pursuant to clause (e) of
this Section 3, to register or qualify such Registrable Securities, have been
complied with, assuming the accuracy and completeness of the information
furnished to such counsel with respect to each filing relating to such laws; it
being understood that said counsel may rely, as to all factual matters and
financial data treated therein, on certificates of


                                       15
<PAGE>   16
     the Company (copies of which shall be delivered to such Holders), and as to
     all questions of the laws of each state in which the Company shall be so
     required to register or qualify such Registrable Securities, on the opinion
     of counsel from such state reasonably acceptable to such Holder, copies of
     which shall be delivered to such Holder; and

(k)  upon reasonable notice to and consultation with the Company, make available
for inspection by the Holder and any attorney or accountant retained by the
Holder all financial and other records, pertinent corporate documents and
properties of the Company reasonably necessary in order for the Holder to sell
its Shares pursuant to the Registration Statement; provided that such Persons
shall agree in a writing satisfactory in form and substance to the Company to
keep confidential any records, information or documents of the Company unless a
court or administrative agency requires the disclosure of the records,
information or documents or such records, information or documents (A) become
generally available to the public other than as result of a disclosure by any
such Persons, (B) were available to such Persons on a non-confidential basis
prior to the disclosure of such records, information or documents pursuant to
this Exhibit C, or (C) become available to such Persons on a non-confidential
basis from a source other than the Company or its agents, advisors or
representatives.

The Company may require the Holder to furnish to the Company information
regarding the Holder and the distribution of the Registrable Securities as the
Company may from time to time reasonably request in writing and as necessary for
the registration of the Shares.

Upon receipt of any notice from the Company of the happening of any of the
following: (i) the SEC's issuance of any stop order denying or suspending the
effectiveness of the Registration Statement or the initiation of any proceeding
for that purpose, (ii) the Company's receipt of any stop order denying
registration or suspending the qualification of the Registrable Securities for
sale or the initiation of any proceeding for such purpose, (iii) the happening
of any event which makes any statement made in the Registration Statement, the
Prospectus or any document incorporated by reference therein untrue or which
requires any change in the Registration Statement, the Prospectus or any
document incorporated by reference therein to make the statements not include an
untrue statement of material fact or not omit any material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing, the Holder shall discontinue the
disposition of Registrable Securities until the Holder receives a supplemented
or amended Prospectus from the Company or until the Company advises the Holder
in writing that the Holder may resume the use of the Prospectus, and have
received copies of any additional or supplemental filings which are incorporated
by reference in the Prospectus. If the Company so directs, the Holder will
deliver to the Company (at the Company's expense) all copies, other than
permanent file copies then in the Holder's possession, of the Prospectus
covering the Registrable Securities at the time the Holder received the notice.

4.   Registration Expenses. Regardless of when the Registration Statement
becomes effective, the Company shall bear all costs and expenses incident to the
Company's performance of, or compliance with, this Exhibit C, including without
limitation all registration and filing fees, fees and expenses of compliance
with the Blue Sky Laws, printing expenses, messenger, telephone and


                                       16
<PAGE>   17

     delivery expenses, Nasdaq qualification and listing fees, and fees and
     disbursements of counsel for the Company, all independent certified public
     accountants of the Company and fees and expenses of other Persons retained
     by the Company relating to the distribution of the Registrable Securities
     (all such expenses being herein called "Registration Expenses"). The Holder
     shall pay all discounts and commissions attributable to the Registrable
     Securities, all transfer taxes relating to the sale or disposition of the
     Registrable Securities and any fees of any attorney or accountant retained
     by the Holder.

5.   Disclosure. With a view to making available registration on Form S-3 and
the benefits of Rule 144 under the Securities Act, the Company agrees, for a
period two years following the earlier of (x) five (5) years after the date of
this Exhibit A and (y) the date upon which the Holder has purchased from the
Company all of the Shares available under the Warrant, to:

(a)  make and keep current public information available within the meaning of
     Rule 144(c) of the Securities Act;
(b)  file with the SEC in a timely manner all reports and other documents and
     information required of the Company under the Exchange Act, and take such
     other actions as may be necessary to assure the availability of Form S-3
     for use in connection with the registration rights provided in this Exhibit
     A; and
(c)  furnish to the Holder forthwith upon request a written statement as to the
     Company's compliance with the reporting requirements of Rule 144 and the
     Exchange Act, a copy of the Company's most recent annual and quarterly
     reports, and such other reports, documents and other information in the
     possession of or reasonably obtainable by the Company as the Holder may
     reasonably request in availing itself of Rule 144.


6.   Indemnification.
(a)  Indemnification by the Company. The Company agrees to indemnify and hold
harmless, to the full extent permitted by law, the Holder against all losses,
claims, damages, liabilities and expenses (including, without limitation,
reasonable attorneys' fees and expenses) to which the Holder may become subject
under federal or state securities laws or otherwise which arise out of, or are
caused by, the Company's violation of any federal or state securities laws,
including, but not limited to, any untrue or alleged untrue statement of a
material fact contained in any Registration Statement, Prospectus or preliminary
prospectus or in any application or other request that the Company files in
connection with the registration contemplated by such Registration Statement,
including any application or request filed under the Blue Sky Laws 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,
except insofar as the same are caused by or contained in any written information
furnished to the Company by the Holder expressly for use therein; provided,
however, the Company will not be liable in any such case to the extent that any
such loss, claim, damage, liability or expense results from the fact that the
Holder sold Registrable Securities to a Person to whom there was not sent or
given, at or prior to the written confirmation of such sale, a copy of the final
prospectus or of the final prospectus as then amended or supplemented, whichever
is most recent, if the Company had previously made available to the Holder a
sufficient number of copies thereof and such final prospectus, as then amended
or

                                       17
<PAGE>   18

supplemented, corrected such misstatement or omission.

(b)  Indemnification by the Holder. In connection with any Registration
Statement in which the Holder's Registrable Securities are registered and sold,
the Holder shall furnish to the Company such information and affidavits as the
Company reasonably requests for use in connection with any Registration
Statement or Prospectus and agrees to indemnify and hold harmless, to the full
extent permitted by law, the Company, its officers, directors and each Person
who controls the Company (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses (including, without
limitation, reasonable attorneys' fees and expenses) resulting from any untrue
or alleged untrue statement of a material fact or any omission or alleged
omission of a material fact required to be stated in the Registration Statement,
Prospectus, preliminary Prospectus or any application filed under the Blue Sky
Laws or necessary to make the statements therein not misleading, but only to the
extent that the untrue statement or omission is contained in any written
information or affidavit so furnished by the Holder to the Company expressly for
inclusion in the Registration Statement, Prospectus or application filed under
the Blue Sky Laws or results from the fact that the Holder sold Registrable
Securities to a Person to whom there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the final prospectus or of the
final prospectus as then amended or supplemented, whichever is most recent, if
the Company had previously made available a sufficient number of copies thereof
to the Holder and such final prospectus, as then amended or supplemented,
corrected such misstatements or omission.

(c)  Conduct of Indemnification Proceedings. Any Person entitled to
indemnification hereunder shall (i) promptly notify the indemnifying party of
any claim with respect to which it seeks indemnification and (ii) permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any Person entitled to indemnification
hereunder shall have the right to employ separate counsel and to participate in
the defense of the claim, but the fees and expenses of the counsel shall be at
the expense of the Person unless (A) the indemnifying party has agreed to pay
the fees or expenses, (B) the indemnifying party shall have failed to assume the
defense of the claim and employ counsel reasonably satisfactory to the Person,
or (C) in the reasonable judgment of the Person, based upon advice of its
counsel, a conflict of interest may exist between the Person and the
indemnifying party with respect to the claims (in which case, if the Person
notifies the indemnifying party in writing that the Person elects to employ
separate counsel at the expense of the indemnifying party, the indemnifying
party shall not have the right to assume the defense of the claim on behalf of
the Person), and in no event (except as set forth in the last sentence of this
Section 6(c)), shall the Holder have the right to employ more than one separate
counsel at the Company's expense for all of them for any matter. If the
indemnifying party assumes the defense, the indemnifying party will not be
subject to any liability for any settlement made without its consent. The
indemnifying party, however, may not unreasonably withhold its consent. No
indemnifying party will be required to consent to the entry of any judgment or
to enter into any settlement which does not include as an unconditional term the
claimant's or plaintiff's release of the indemnified party from all liability in
respect to the claim or litigation. An indemnifying party who is not entitled
to, or elects not to, assume the defense of a claim shall not be obligated to
pay the fees and expenses of more than one counsel in any jurisdiction for all
parties indemnified by the indemnifying party with

                                       18
<PAGE>   19

respect to the 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 the claim, in which event the
indemnifying party shall be obligated to pay the fees and expenses of such
additional counsel or counsels.
(d)  Survival. The indemnities provided in this Section 6 shall survive the
Holder's transfer of any Registrable Securities.
