Preferred Shares to any Person unless the Shareholder seeking to make the
transfer (the "Transferor") shall first have made the written offer to sell
described in Section 4.2 below (the "Offer") and that Offer has not been
accepted pursuant to the terms of this Shareholders' Agreement.

                  4.2. Offer by Transferor. The Offer referred to in Section
4.1 shall be given by the Transferor to the Company and to each of the other
Shareholders (,herein the "Non-Offering Shareholders") and shall consist of a
written Offer to sell all the Offered Shares which the Transferor then intends
to dispose of, to which Offer shall be attached a statement of intention to
dispose of the Offered Shares pursuant to a bona fide offer from a prospective
purchaser or purchasers (the "Transferee"), a description of the contemplated
disposition, the name and address of each bona fide Transferee, the number of
Preferred Shares involved in and other terms (the "Terms") of the proposed
disposition. The Terms shall include, without limitation, the purchase price
per Offered Share offered by each Transferee and the manner in which such
purchase price shall be paid to the Transferor. Such Offer shall be signed by
the Transferor and shall remain irrevocable until the earlier of (a) the time
at which all of the Offered Shares are accepted by the Company or the Non-
Offering Shareholders, as provided in Sections 4.3 and 4.4 or (b) one hundred
twenty (120) days after the "Offer Date," which date shall be the date on which
a notice is given to the Company and such Non-Offering Shareholders in
accordance with the terms of Section 12.1 of this Shareholders' Agreement. The
date on which the Offer becomes revocable is referred to herein as the
"Expiration Date."

                  4.3. Acceptance of Offer by the Company. The Company may, at
its option exercise within sixty (60) days after the Offer Date, elect to
purchase all or any portion of the Offered Shares on the Terms (with the
designees of the selling Shareholder abstaining on any vote of the Board of
Directors of the Company with respect to such purchase). If and to the extent
the Company does not accept the Offer in accordance with this Section 4.3 with
respect to all of the Offered Shares, the Offered Shares may be disposed of in
accordance with Section 4.4. The Company shall exercise its option under this
Section 4.3 by giving an Exercise Notice. The Exercise Notice shall be in
accordance with the Terms. Any purchase by the Company of one hundred percent
(100%) of the Offered Shares shall be completed not later than ninety (90) days
after the Offer Date (subject to any extension of time required to permit
necessary governmental or regulatory filings, notices or approvals).

                  4.4. Acceptance of Offer by Shareholders. If and to the
extent the Company does not accept the Offer with respect to all of the Offered
Shares in accordance with the provisions of Section 4.3, the remaining Offered
Shares shall be deemed to be offered to the Non-Offering Shareholders and each
Non-Offering Shareholder may, at its option exercised within ten (10) days
after (i) the last day of the exercise period pursuant to Section 4.3 or, if
earlier (ii) the date on which the Company notifies the Shareholders of its
election to purchase less than all (or none) of the Offered Shares, elect to
purchase not more than its Proportion of the remaining Offered Shares. Each
Non-Offering Shareholder who exercises its option to purchase its Proportion of
the Offered Shares shall do so by giving an Exercise Notice. In the event that
any such Non-Offering Shareholder gives an Exercise Notice covering less than
its Proportion of the Offered Shares


                                     - 6 -

<PAGE>   7



available to be purchased by Non-Offering Shareholders (such shares not covered
by Exercise Notices being referred to as the "Balance"), each of the
Non-Offering Shareholders that time delivered an Exercise Notice covering its
full Proportion of the Offered Shares available to be purchased by Non-Offering
Shareholders, may, by a second Exercise Notice delivered within ten (10) days
after the expiration of the first ten (10) day period referred to above, elect
to purchase up to that number of Offered Shares that is equal to the product of
the Balance multiplied by a fraction, the numerator of which shall be such
Non-Offering Shareholder's Proportion of the number of Offered Shares first
made available for purchase by Non-Offering Shareholders pursuant to this
Section 4.4, and the denominator of which shall be the total number of such
Offered Shares covered by the first Exercise Notices timely delivered by all
Non-Offering Shareholders which purchased their respective full Proportions.
If, after the expiration of the second ten (10) day period any Offered Shares
remain available to be purchased, any Non-Offering Shareholder which has timely
delivered Exercise Notices covering the maximum number of Offered Shares
available to it, may notify the Company, within five (5) days after the
expiration of such second ten (10) day period of its desire to purchase
additional Offered Shares, specifying the maximum number of such Offered Shares
it is willing to purchase. If more than one such notice is received by the
Company, the number of additional Offered Shares shall be allocated to the
Non-Offering Shareholders delivering such notices in the same proportion as
their respective offers bear to the total number of Offered Shares available in
the third and final round.

                  4.5. Purchases by Company and Shareholders. If the Company
and the Non- Offering Shareholders together, or the Non-Offering Shareholders
(or any of them) alone, elect to purchase 100% of the Offered Shares, the sale
and purchase of such shares shall be completed not later than one hundred and
five (105) days after the Offer Date (subject to any extension of time required
to permit necessary governmental or regulatory filings, notices or approvals).
The Transferor shall not be obligated to sell any Offered Shares to the Company
or to any Non-Offering Shareholder unless the Company and/or the Non-Offering
Shareholders have agreed to purchase, and purchase, 100% of the Offered Shares.
"Completion" of any sale pursuant to this Article 4 shall mean, at a minimum,
delivery by the selling Shareholder to each purchaser of certificate(s)
representing the number of Preferred Shares to be sold, in form for transfer by
delivery, and payment by each purchaser of the purchase price therefor in
accordance with the Terms, or as may otherwise be agreed by the parties.

         5.       SALE OF OFFERED SHARES TO TRANSFEREE.

         If the Non-Offering Shareholders and the Company do not elect to
purchase all of the Offered Shares in accordance with the terms of Sections 4.3
and 4.4 the Transferor shall not be obligated to sell any of the Offered Shares
to the Non-Offering Shareholders or the Company and shall be entitled to
dispose of all of the Offered Shares to the Transferee on the Terms, provided
that such disposition is consummated within one hundred fifty (150) days
(subject to any extension of time required to permit necessary governmental or
regulatory filings, notices or approvals) after the Offer Date and the
Transferee executes a counterpart of this Shareholders' Agreement and agrees to
remain bound by all terms of this Shareholders' Agreement. Any proposed
transfer on terms and conditions


                                     - 7 -

<PAGE>   8



other than the Terms, as well as any subsequent proposed transfer of Preferred
Shares by such Shareholder, shall again be subject to the rights of the Company
and the Non-Offering Shareholders and shall require compliance by Transferor
with the procedures described in Article 4.

         6.       EFFECTS OF NON-PARTICIPATION.

         The exercise or non-exercise of the rights of any Shareholder or the
Company under Article 4 to participate in one or more sales of shares of Stock
made by the Company or any Shareholder shall not adversely affect such
Shareholder's or the Company's right, as applicable, to participate in
subsequent sales of shares of Stock subject to Article 4.

         7.       REGISTRATION RIGHTS.

                  7.1. Company Registration. If at any time after the date of
this Shareholders' Agreement the Company proposes to register (including for
this purpose a registration effected by the Company for shareholders other than
the Holders) any of its stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash (other
than a registration relating solely to the sale of securities to participants
in a Company stock plan, or a registration relating to shares to be issued in
connection with the acquisition of another company, or 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 the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder made within (30) days after the Company shall have given such notice in
accordance with Section 12.1 hereof, the Company shall, subject to the
provisions of Section 7.5, use all reasonable efforts to cause to be registered
under the Securities Act all of the Registrable Securities that each such
Holder has requested to be registered.

                  7.2. Obligations of the Company. Whenever required under this
Article 7 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a)  Prepare and file with the SEC a registration statement
         with respect to such Registrable Securities and use all reasonable
         efforts to cause such registration statement to become effective, and,
         upon the request of the Holders of a majority of the Registrable
         Securities registered thereunder, keep such registration statement
         effective for up to one hundred twenty (120) days;

                  (b)  Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection with such registration statement as may be necessary to
         comply with the provisions of the Securities Act with respect to the
         disposition of all securities covered by such registration statement;


                                     - 8 -

<PAGE>   9



                  (c)  Furnish to the Holders such numbers of copies of a
         prospectus, including a preliminary prospectus, in conformity with the
         requirements of the Securities Act, and such other documents as they
         may reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them;

                  (d)  Use all reasonable efforts to register and qualify the
         securities covered by such registration statement under such other
         securities or blue sky laws of such jurisdictions as shall be
         reasonably requested by the Holders, provided, however, that the
         Company shall not be required in connection therewith or as a
         condition thereto to qualify to do business or to file a general
         consent to service of process in any such states or jurisdictions; and

                  (e)  Enter into and perform its obligations under an
         underwriting agreement, in usual and customary form, with the managing
         underwriter of such offering. Each Holder participating in such
         underwriting shall also enter into and perform its obligations under
         such an agreement.

                  7.3. Furnish Information. It shall be a condition precedent
to the obligations of the Company to take any action pursuant to this Article 7
that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be reasonably and customarily
required to effect the registration of the Registrable Securities.

                  7.4. Expenses of Company Registration. The Company shall bear
and pay all, expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 7.1 for each Holder (which right may be assigned as
provided in Section 7.10), including (without limitation) all registration,
filing and qualification fees, printers' and accounting fees relating or
apportionable thereto and the reasonable fees and disbursements (not to exceed
US $50,000) of one counsel for the selling Holders selected by them, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

                  7.5. Underwriting Requirements. In connection with any
offering involving an underwriting of shares being issued by the Company, the
Company shall not be required under Section 7.1 to include any of the Holders'
securities in such underwriting unless such Holder accepts the terms of the
underwriting as agreed upon between the Company and the underwriters selected
by the Company, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company. If the
total amount of securities, including Registrable Securities, requested by
shareholders to be included in an offering exceeds the amount of securities to
be sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of Registrable Securities which the
underwriters believe will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling
shareholders according to the total amount of securities requested to be
included therein

                                     - 9 -

owned by each selling shareholder or in such other proportions as shall
mutually be agreed to by such selling shareholders).

                  If any Person does not agree to the terms of any such
underwriting, it shall be excluded therefrom by written notice from the Company
or the underwriter. Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration. If shares are so
withdrawn from the registration, the Company shall then offer to all Persons
who have retained the right to include securities in the registration the right
to include additional securities in the registration in an aggregate amount
equal to the number of shares so withdrawn, with such shares to be allocated
among the Persons requesting additional inclusion pro rata according to the
total amount of securities requested to be included in such registration owned
by each such Person or in such other proportions as shall be mutually agreed by
such selling shareholders.

                  For purposes of the immediately preceding paragraph
concerning apportionment, for any selling shareholder which is a holder of
Registrable Securities and which is a partnership or corporation, the partners,
retired partners and shareholders of such Holder, or the estates and family
members of any such partners and retired partners, and any trusts for the
benefit of any of the foregoing Persons shall be deemed to be a single "selling
shareholder," and any pro rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder," as defined in this sentence.

                  7.6. Delay of Registration. No Holder shall 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 this Article 7.

                  7.7. Indemnification. In the event any Registrable Securities 
are included in a registration statement under this Article 7:

                  (a)  To the extent permitted by law, the Company will
         indemnify and hold harmless each Holder, the officers, directors,
         partners, employees and legal counsel of each Holder, and each Person,
         if any, who controls such Holder within the meaning of the Securities
         Act or the Exchange Act, against any losses, claims, damages or
         liabilities (joint or several) to which they may become subject under
         the Securities Act, the Exchange Act or any other federal or state
         law, rule or regulation insofar as such losses, claims, damages or
         liabilities (or actions in respect thereof) arise out of or are based
         upon any of the following statements, omissions or violations
         (collectively, a "Violation"): (i) any untrue statement or alleged
         untrue statement of a material fact contained in such registration
         statement, including any preliminary prospectus or final prospectus
         contained therein or any amendments or supplements thereto, (ii) the
         omission or alleged omission to state therein a material fact required
         to be stated therein, or necessary to make the statements therein not
         misleading in light of the circumstances in which they were made, or
         (iii) any violation or alleged violation


                                     - 10 -

<PAGE>   11



         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; and the
         Company will reimburse each such Holder, officer, director, partner,
         employee, legal counsel, underwriter or controlling Person for any
         legal or other expenses reasonably incurred by them in connection with
         investigating or defending any such loss, claim, damage, liability or
         action or enforcing these indemnification provisions, as such expenses
         are incurred; provided, however, that the indemnity agreement
         contained in this subsection 7.7(a) shall not apply to amounts paid in
         settlement of any such loss, claim, damage, liability or action if
         such settlement is effected without the consent of the Company, nor
         shall the Company be liable in any such case for any such loss, claim,
         damage, liability or action to the extent that it arises out of or is
         based upon a Violation which occurs in reliance upon and in conformity
         with written information shed expressly for use in connection with
         such registration by any such Holder.

                  (b) To the extent permitted by law, each selling Holder will
         indemnify and hold harmless the Company, each of its directors and
         officers, its legal counsel, each Person, if any, who controls the
         Company within the meaning of the Securities Act, and any other Holder
         selling securities in such registration statement or any of such other
         Holder's directors, officers, employees, legal counsel or any Person
         who controls such Holder, against any losses, claims, damages or
         liabilities (joint or several) to which the Company or any such
         director, officer, employee, legal counsel, or controlling Person, or
         other such Holder or director, officer, employee, legal counsel or
         controlling Person of such other Holder may become subject, under the
         Securities Act, the Exchange Act or other federal or state law,
         insofar as such losses, claims, damages or liabilities (or actions in
         respect thereto) arise out of or are based upon any Violation, in each
         case to the extent (and only to the extent) that such Violation occurs
         in reliance upon and in conformity with written information furnished
         by such Holder expressly for use in connection with such registration;
         and each such Holder will reimburse any legal or other expenses
         reasonably incurred by the Company or any such director, officer,
         employee, legal counsel, controlling Person, other Holder, or officer,
         director, employee, legal counsel, or controlling Person of such other
         Holder in connection with investigating or defending any such loss.
         claim, damage, liability, or action or enforcing these
         indemnifications provisions, as such expenses are incurred; provided,
         however, that the indemnity agreement contained in this subsection
         7.7(b) shall not apply to amounts paid in settlement of any such loss,
         claim, damage, liability or action if such settlement is effected
         without the consent of the indemnifying Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 7.7 of notice of the commencement of any action (including any
         governmental action), such indemnified party will, if a claim in
         respect thereof is to be made against any indemnifying party under
         this Section 7.7, give to the indemnifying party a written notice of
         the commencement thereof and the indemnifying party shall have the
         right to participate in, and, to the extent the indemnifying party so
         desires, jointly with any other indemnifying party similarly noticed,
         to assume the defense thereof with counsel mutually satisfactory to
         the parties; provided,


                                     - 11 -

<PAGE>   12



         however, that an indemnified party shall have the right to retain its
         own counsel at its own expense if it so desires. Notwithstanding the
         foregoing, if the indemnified party and the indemnifying party have
         conflicting interests with respect to the action so that joint counsel
         for them would be inappropriate (as determined by counsel to the
         indemnified party and counsel to the indemnifying party), then the
         indemnifying party shall pay reasonable fees and expenses of one
         counsel to the indemnified party. Each indemnified party shall give
         reasonably prompt notice to each indemnifying party or parties of any
         action or proceeding commenced against it in respect of which
         indemnity may be sought hereunder, but the failure to deliver written
         notice to the indemnifying party within a reasonable time of the
         commencement of any such action, shall not relieve such indemnifying
         party of any liability to the indemnified party under this Section
         7.7, unless the indemnifying party is materially prejudiced by such
         failure to give notice.

                  (d) If the indemnification provided for in this Section 7.7
         is held by a court of competent jurisdiction to be unavailable to an
         indemnified party or insufficient to hold harmless an indemnified
         party under subsection (a), (b), or (c) above, then each indemnifying
         party shall contribute to the amount paid or payable by such
         indemnified party as a result of the losses, claims, damages or
         liabilities referred to in subsection (a), (b), or (c) above, in such
         proportion as is appropriate to reflect the relative fault of the
         indemnifying party on the one hand and of the indemnified party on the
         other in connection with the action, statement or omission that
         resulted in such claims, as well as other equitable considerations.
         The relative fault shall be determined with reference to, among other
         things, whether the untrue statement or alleged omission to state a
         material fact relates to information supplied by the indemnifying
         party or such indemnified party and the parties' relative intent,
         knowledge, access to information and opportunity to correct or prevent
         such statement or omission. Notwithstanding the foregoing provisions
         of this Section 7.7, a Holder of Registrable Securities shall not, as
         an indemnifying party, be required to contribute any amount in excess
         of (x) the amount by which the total price at which the Registrable
         Securities sold by such indemnifying party were offered to the public
         exceeds (y) the amount of any damages which such indemnifying party
         has otherwise been required to pay by reason of such action, untrue or
         alleged untrue statement or omission or alleged omission. The Company
         and each Holder of Registrable Securities agrees that it would not be
         just and equitable if contribution pursuant to this Section 7.7(d)
         were determined by pro rata allocation or by any other method of
         allocation which does not take account of the equitable considerations
         referred to above in this Section 7.7(d). The amount paid or payable
         by an indemnified party as a result of the losses, claims, damages or
         liabilities referred to above in this Section 7.7(d) shall be deemed
         to include any legal or other expenses reasonably incurred by such
         indemnified party in connection with investigation or defense of any
         such action or claim which is the subject of this subsection (d) or
         enforcement of these contribution provisions.

                  (e) The obligations of the Company and Holders under this
         Section 7.7 shall survive the completion of any offering of
         Registrable Securities in a registration statement under this Article
         7, and otherwise.

                  7.8. Reports Under Securities Exchange Act. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to:

                  (a)  make and keep public information available, as those
         terms are understood and defined in SEC Rule 144, at all times;

                  (b)  file with the SEC in a timely manner all reports and
         other documents required of the Company under the Securities Act and
         the Exchange Act; and

                  (c)  furnish to any Holder, so long as the Holder owns any
         Registrable Securities, forthwith upon request (i) a written statement
         by the Company that it has complied with the reporting requirements of
         SEC Rule 144, the Securities Act and the Exchange Act (at any time
         after it has become subject to such reporting requirements), and (ii)
         a copy of the most recent annual or quarterly report of the Company
         and such other reports and documents so filed by the Company.

                  7.9. Form S-3 Registration. In case the Company shall receive
at any time after ninety (90) days from the Closing Date written request or
requests from a Holder that the Company effect a registration on Form S-3 and
any related qualification or compliance with respect to all or a part of the
Registrable Securities owned by such Holder or Holders, the Company will:

                  (a)  promptly give written notice of the proposed 
         registration, and any related qualification or compliance, to all
         other Holders; and

                  (b)  as soon as practicable, effect such registration and all
         such qualifications and compliances as may be so requested and as
         would permit or facilitate the sale and distribution of all such
         portion of such Holder's or Holders' Registrable Securities as are
         specified in such request, together with all or such portion of the
         Registrable Securities of any other Holder or Holders joining in such
         request as are specified in a written request made within thirty (30)
         days after the Company shall have given such notice pursuant to
         Section 12.1 hereof; provided, however, that the Company shall not be
         obligated to effect any such registration, qualification or compliance
         pursuant to this Section 7.9 (i) if Form S-3 is not available for such
         offering by the Holders; (ii) if the Holders, together with the
         holders of any other securities of the Company entitled to inclusion
         in such registration, propose to sell Registrable Securities and such
         other securities (if any) at an aggregate price to the public of less
         than Five Million Dollars (US $5,000,000); (iii) if the Company shall
         furnish to the Holders a certificate signed by the CEO stating that in
         the good faith judgment of the Board of Directors it would be
         seriously detrimental to the Company and its stockholders for such
         Form S-3 Registration to be effected at such time, in which event the
         Company shall have the right to defer the filing of the Form S-3
         Registration Statement for a period of not more than one hundred
         eighty (180) days after receipt of the request of the Holder or
         Holders


                                     - 13 -

<PAGE>   14



         under this Section 7.9; provided, however, that the Company shall not
         utilize this right more than once in any 12 month period; (iv) if the
         Company within the nine month period preceding the date of such
         request, already has effected one registration on Form S-3 for the
         Holders pursuant to this Section 7.9 or within the 48 month period
         preceding the date of such request already has effected five such
         registrations and other similar provisions granting rights to the
         registration on Form S-3; or (v) in any particular jurisdiction in
         which the Company would be required to qualify to do business or to
         execute a general consent to service of process in effecting such
         registration, qualification or compliance.

                  Subject to the foregoing, the Company shall file a
         registration statement covering the Registrable Securities and other
         securities so requested to be registered (including securities which
         the Company wishes to issue), as soon as practicable after receipt of
         the request or requests of the Holders. All expenses, other than
         underwriting discounts and commissions, incurred in connection with
         the registrations pursuant to this Section 7.9, including (without
         limitation) all other registration, filing, qualification, printer's
         and accounting fees shall be borne by the Company.

                  7.10. Assignment of Registration Rights. The rights to cause
the Company to register Registrable Securities pursuant to this Article 7 may
be assigned by a Holder to a transferee or assignee who has lawfully received
the shares in a private sale in accordance with all applicable laws and
regulations and with respect to Registrable Securities, the terms of this
Shareholders' Agreement; provided, however, in each case, the Company is,
within a reasonable period of time after such transfer, given written notice of
the name and address of such transferee or assignee and the securities with
respect to which such registration rights are being assigned; and provided,
further, that such assignment shall be effective only if (i) immediately
following such transfer the further disposition of any such securities by the
transferee or assignee is restricted under the Securities Act and (ii) the
transferee agrees to be bound by the terms of this Article 7.

                  7.11. Amendment of Registration Rights. Any provision of this
Article 7 may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders of
at least seventy percent (70%) of the Registrable Securities. Any amendment or
waiver effected in accordance therewith shall be binding upon each holder of
any securities purchased under this Shareholders' Agreement at the time
outstanding (including securities into which such securities are convertible),
each future holder of all such securities, and the Company; provided, however,
that no such amendment or the waiver of the observance of any provisions of
this Article 7 that adversely affect the rights of Vulcan Ventures Incorporated
may occur without Vulcan Ventures Incorporated's consent.

                  7.12. Termination of Registration Rights. The Company's
obligations pursuant to this Article 7 shall terminate with respect to each
Holder upon the earlier to occur of (i) five (5) years after the Closing Date
or (ii) such time as such Holder may sell all of its Registrable Securities


                                     - 14 -

                  approved by both the Principal Shareholder and Rinzai in
                  writing in their respective sole and absolute discretion;

                           8.1.4. In the event that the number of directors
                  making up any of the aforesaid Class I, II or III is
                  increased the individuals who make up the such additional

been approved by both the Principal Shareholder and Rinzai for the purposes of
this Section 8.1.

                  8.2. Termination of Provisions under Certain Circumstances. If
at any time the number of shares of Stock owned or controlled by any of the
Principal Shareholder and Chestnut, or Rinzai (or by any transferee of any
thereof who is entitled, pursuant to the provisions of Section 8.1, to
designate Directors) shall be less than ten percent (10%) of the then issued
and outstanding shares of capital stock of the Company by reason of any sale or
other disposition made by either (i) the Principal Shareholder and Chestnut or
(ii) Rinzai, as applicable, this Article 8 shall terminate and be of no further
force and effect. 'This Agreement shall terminate as to Howard, and Howard

         11.      SPECIFIC PERFORMANCE.

         The Shareholders, the Company and Howard acknowledge and agree that
the recovery of money damages will not constitute an adequate remedy for breach
of the provisions of this Shareholders' Agreement. Accordingly, the parties
agree that the provisions of this Shareholders' Agreement may be specifically
enforced against them and transferees of securities of the Company which are
subject to this Shareholders' Agreement (in addition to any other remedies
available for breach of this Shareholders' Agreement), and the parties (for
themselves and, in the case of the Shareholders, transferees of their
securities of the Company), hereby waive the defense in any equitable
proceeding that there is an adequate remedy at law for any such breach.

         12.      MISCELLANEOUS.

                  12.5. Amendments and Waivers. Except as expressly provided in

by any of them of any Voting Agreement (and related Proxy), Affiliate

contemplated by the Merger Agreement or otherwise entered into in connection
with the Merger Agreement nor the consummation of any of the actions or
transaction contemplated thereby shall constitute a breach of the Hayes'
