registration under the Securities Act of Registrable Shares. Then the Company
shall (subject to the managing underwriter's discretion) promptly give written
notice of such proposed registration to all holders of Registrable Shares and
shall (subject to the managing underwriter's discretion) offer to include in
such proposed registration any Registrable Shares requested to be included in
such proposed registration by all holders of Registrable Shares who respond in
writing to the Company's notice within 30 days after delivery of such notice
(which response shall specify the number of Registrable Shares proposed to be
included in such registration). The Company shall use its best efforts to
promptly effect the registration under the Securities Act of the Registrable
Shares which the Company has been so requested to register. The number of
requests permitted pursuant to this Section 2(a) shall be unlimited.

                  (b) Anything contained in Section 2(a) to the contrary
notwithstanding, the Company shall not be obligated to effect any registration
under the Securities Act pursuant to Section 2(a) except in accordance with the
following provisions:

                           (i) with respect to any registration pursuant to this
         Section 2, the Company may include in such registration any Primary
         Shares or Other Shares; provided, however, that if the managing
         underwriter advises the Company that the inclusion of all Registrable
         Shares, Primary Shares and/or Other Shares proposed to be included in
         such registration would interfere with the successful marketing
         (including pricing) of the Registrable Shares proposed to be included
         in such registration, then the number of Registrable Shares, Primary
         Shares and/or Other Shares proposed to be included in such registration
         shall be included in the following order:

                                    (A) first, all Registrable Shares requested
                  to be included in such registration by the Shareholders who
                  requested such registration or made timely notice to the
                  Company of their request to include Registrable Shares in such
                  registration pursuant to Section 2(a), pro rata among such
                  requesting Shareholders based on the number of Registrable
                  Shares requested by each such requesting Shareholder to be so
                  registered;

                                    (B) second, all Registrable Shares requested
                  to be included in such registration by the other Shareholders
                  who requested the inclusion of their Registrable Shares in
                  such registration pursuant to Section 3, pro



                                       4
<PAGE>   7

                  rata among all such Shareholders based on the number of
                  Registrable Shares requested by each such Shareholder to be so
                  registered;

                                    (C) third, the Primary Shares; and

                                    (D) fourth, the Other Shares;

                           (ii) at any time before the Registration Statement
         covering Registrable Shares becomes effective, the Shareholder or group
         of Shareholders which requested such registration pursuant to Section
         2(a) may request the Company to withdraw or not to file the
         Registration Statement; and

                           (iii) the Company may, at its sole option, elect to
         satisfy a request for a registration pursuant to Section 2(a) on Form
         S-2 or Form S-3 promulgated under the Securities Act (or any successor
         forms thereto), if such forms are then available to the Company.

                  (c) The Company shall file a registration statement with
respect to each registration requested pursuant to Section 2(a) as soon as
practicable after receipt of the demand of the requesting Shareholders;
provided, however, that if in the good faith judgment of the Board of Directors
of the Company, such registration would be seriously detrimental to the Company
in that such registration would interfere with a proposed primary registration
of securities by the Company or any other material corporate transaction and the
Board of Directors concludes, as a result, that it is advisable to defer the
filing of such registration statement at such time (as evidenced by an
appropriate resolution of the Board), then the Company shall have the right to
defer such filing for the period during which such registration would be
seriously detrimental; provided, further, however, that (i) the Company may not
defer the filing for a period of more than one hundred and twenty (120) days
after receipt of the demand of the requesting Shareholders, (ii) the Company
shall not exercise its right to defer such a registration more than once, and
(iii) if the Company undertakes a primary registration following an exercise of
its deferral right, the holders of Registrable Shares shall have "piggyback"
rights under Section 3 hereof with respect to not less than one-third (1/3) of
the number of shares of Registrable Shares to be sold in such offering.

         SECTION 3. PIGGYBACK REGISTRATION.

                  If the Company at any time that is 180 days after its initial
Public Offering proposes for any reason to register shares of Common Stock under
the Securities Act (other than on Form S-4 or Form S-8 promulgated under the
Securities Act or any successor forms thereto), it shall promptly give written
notice to the Shareholders of its intention to so register such shares and, upon
the written request, delivered to the Company within 20 days after delivery of
any such notice by the Company, of any Shareholder to include in such
registration Registrable Shares (which request shall specify the number of
Registrable Shares proposed to be included in such registration), the Company
shall use its best efforts to cause all such Registrable Shares to be included
in



                                       5
<PAGE>   8
such registration on the same terms and conditions as the Common Stock otherwise
being sold in such registration; provided, however, that if the managing
underwriter advises the Company that the inclusion of all Registrable Shares
requested to be included in such registration would interfere with the
successful marketing (including pricing) of the Primary Shares or Other Shares
proposed to be registered by the Company, then the number of Primary Shares,
Registrable Shares and Other Shares proposed to be included in such registration
shall be included in the following order:

                           (i) first, the Primary Shares or Other Shares
         proposed to be registered by the Company; and

                           (ii) second, the Registrable Shares requested to be
         included in such registration pursuant to this Section 3, pro rata
         among the holders thereof based upon the number of Registrable Shares
         requested to be registered by each such holder; and

                           (iii) any Other Shares.

         SECTION 4. REGISTRATIONS ON FORM S-3.

                  Anything contained in Section 2 to the contrary
notwithstanding, at such time as the Company shall have qualified for the use of
Form S-3 promulgated under the Securities Act or any successor form thereto, a
Majority of Shareholders shall have the right to request in writing an unlimited
number of registrations of Registrable Shares on Form S-3 or such successor
form, which request or requests shall (i) specify the number of Registrable
Shares intended to be sold or disposed of and the holders thereof, (ii) state
the intended method of disposition of such Registrable Shares and (iii) relate
to Registrable Shares having an anticipated aggregate gross offering price
(before underwriting discounts and commissions) of at least $10,000,000, and
upon receipt of any such request, the Company shall use its best efforts
promptly to effect the registration under the Securities Act of the Registrable
Shares so requested to be registered. A requested registration on Form S-3 or
any such successor form in compliance with this Section 4 shall be treated as a
registration initiated pursuant to, and shall be subject to, the provisions of
Section 2.

         SECTION 5. HOLDBACK AGREEMENT.

                  (a) If the Company at any time shall register shares of Common
Stock under the Securities Act (including any registration pursuant to Section
2, Section 3 or Section 4) for sale to the public pursuant to an underwritten
offering, the Shareholders shall not sell publicly, make any short sale of,
grant any option for the purchase of, or otherwise dispose publicly of, any
Registrable Shares (other than those shares of Common Stock included in such
registration pursuant to Sections 2, 3 or 4) without the prior written consent
of the Company, for a period designated by the Company in writing to the
Shareholders, which period shall not begin more than 10 days prior to the
effectiveness of the Registration Statement pursuant to which such public
offering shall be made and shall not last more than 180 days after the closing
of sale of shares pursuant to such



                                       6
<PAGE>   9

Registration Statement. The Company shall use reasonable efforts to obtain the
agreement of any Person permitted to sell shares of Common Stock in a
registration to be bound by and to comply with this Section 5 with respect to
such registration as if such Person was a Shareholder hereunder.

                  (b) If the Company at any time pursuant to Section 2 or
Section 3 of this Agreement shall register under the Securities Act Registrable
Shares held by Shareholders for sale to the public pursuant to an underwritten
offering, the Company shall not effect any public sale or distribution of
securities similar to those being registered, or any securities convertible into
or exercisable or exchangeable for such securities, for such period as shall be
determined by the managing underwriters, which period shall not begin more than
10 days prior to the effectiveness of the Registration Statement pursuant to
which such public offering shall be made and shall not last more than 180 days
after the closing of sale of shares pursuant to such Registration Statement.

         SECTION 6. PREPARATION AND FILING.

                  (a) If and whenever the Company is under an obligation
pursuant to the provisions of this Agreement to use its best efforts to effect
the registration of, and keep effective a Registration Statement for, any
Registrable Shares, the Company shall, as expeditiously as practicable:

                           (i) use its best efforts to cause a Registration
         Statement that registers such Registrable Shares to become and remain
         effective for a period of 90 days (extended for such period of time as
         the Shareholders are required to discontinue disposition of Registrable
         Shares pursuant to Section 6(b) below) or until all of such Registrable
         Shares have been disposed of (if earlier);

                           (ii) use its best efforts to furnish, at least five
         business days before filing a Registration Statement that relates to
         the registration of such Registrable Shares, a Prospectus relating
         thereto or any amendments or supplements relating to such a
         Registration Statement or Prospectus, to one counsel (the
         "Shareholders' Counsel") selected by a Majority of Shareholders, copies
         of all such documents proposed to be filed;

                           (iii) [Intentionally omitted];

                           (iv) notify in writing the Shareholders' Counsel, and
         the Shareholders whose Registrable Shares may be included in such
         Registration Statement, promptly of (A) the receipt by the Company of
         any notification with respect to any comments by the Commission with
         respect to such Registration Statement or Prospectus or any amendment
         or supplement thereto or any request by the Commission for the amending
         or supplementing thereof or for additional information with respect
         thereto, (B) the receipt by the Company of any notification or written
         information with respect to the issuance or threatened issuance by the
         Commission of any stop order suspending the effectiveness of such



                                       7
<PAGE>   10

         Registration Statement or Prospectus or any amendment or supplement
         thereto or the initiation or threatening of any proceeding for that
         purpose (and the Company shall use its best efforts to prevent the
         issuance thereof or, if issued, to obtain its withdrawal) and (C) the
         receipt by the Company of any notification with respect to the
         suspension of the qualification of such Registrable Shares for sale in
         any jurisdiction or the initiation or threatening of any proceeding for
         such purposes;

                           (v) use its best efforts to register or qualify such
         Registrable Shares under such other securities or blue sky laws of such
         jurisdictions as the Shareholders holding such Registrable Shares
         reasonably request and do any and all other acts and things which may
         be reasonably necessary or advisable to enable the Shareholders to
         consummate the disposition in such jurisdictions of the Registrable
         Shares owned by the Shareholders; provided, however, that the Company
         will not be required to qualify generally to do business, subject
         itself to general taxation or consent to general service of process in
         any jurisdiction where it would not otherwise be required to do so but
         for this clause (v);

                           (vi) furnish to the Shareholders holding such
         Registrable Shares such number of copies of a summary Prospectus, if
         any, or other Prospectus, including a preliminary Prospectus, in
         conformity with the requirements of the Securities Act, and such other
         documents as such Shareholders may reasonably request in order to

         Shares;

                           (vii) use its best efforts to cause such Registrable
         Shares to be registered with or approved by such other governmental
         agencies or authorities as may be necessary by virtue of the business
         and operations of the Company to enable the Shareholders holding such
         Registrable Shares to consummate the disposition of such Registrable
         Shares;

                           (viii) notify the Shareholders holding such
         Registrable Shares on a timely basis at any time when a Prospectus
         relating to such Registrable Shares is required to be delivered under
         the Securities Act within the appropriate period mentioned in clause
         (i) of this Section 6(a), of the happening of any event as a result of
         which the Prospectus included in such Registration Statement, as then
         in effect, includes 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 light of the circumstances under which
         they were made, not misleading, and prepare and furnish to such
         Shareholders a reasonable number of copies of, and file with the
         Commission, a supplement to or an amendment of such Prospectus as may
         be necessary so that, as thereafter delivered to the offerees of such
         shares, such Prospectus shall not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading;

                           (ix) subject to the execution of confidentiality
         agreements in form and substance reasonably satisfactory to the
         Company, make available upon reasonable notice and during normal
         business hours, for inspection by the Shareholders holding Registrable
         Shares requested to be included in such registration, any underwriter

         Statement and any attorney, accountant or other agent retained by the
         Shareholders or underwriter (collectively, the "Inspectors"), all
         pertinent financial and other records, pertinent corporate documents
         and properties of the Company (collectively, the "Records"), and cause
         the Company's officers, directors and employees to supply all
         information (together with the Records, the "Information") reasonably
         requested by any such Inspector, in each case as shall be reasonably
         necessary to enable them to exercise their due diligence responsibility
         in connection with such Registration Statement; provided, however, that
         any of the Information that the Company determines in good faith to be
         confidential, and of which determination the Inspectors are so
         notified, shall not be disclosed by the Inspectors unless (A) the
         disclosure of such Information is necessary to avoid or correct a
         misstatement or omission in the Registration Statement or Prospectus,
         (B) the release of such Information is ordered pursuant to a subpoena
         or other order from a court of competent jurisdiction or, upon the
         written advice of counsel, is otherwise required by law, or (C) such
         Information has been made generally available to the public, and the
         Shareholders agree that they will, upon learning that disclosure of
         such Information is sought in a court of competent jurisdiction, give
         notice to the Company and allow the Company, at the Company's expense,
         to undertake appropriate action to prevent disclosure of the
         Information deemed confidential;

                           (x) use its best efforts to obtain from its
         independent certified public accountants "cold comfort" letters in
         customary form and at customary times and covering matters of the type
         customarily covered by cold comfort letters;

                           (xi) use its best efforts to obtain from its counsel
         an opinion or opinions in customary form naming the Shareholders as
         additional addressees or parties who may rely thereon;

                           (xii) provide a transfer agent and registrar (which
         may be the same entity and which may be the Company) for such
         Registrable Shares;

                           (xiii) issue to any underwriter to which the
         Shareholders holding such Registrable Shares may sell shares in such
         offering certificates evidencing such Registrable Shares;

         securities exchange on which any shares of the Common Stock are listed
         or, if the Common Stock is not listed on a national securities
         exchange, use its best efforts to qualify such Registrable Shares for
         inclusion on the Nasdaq National Market;



                                       9
<PAGE>   12

                          (xv) otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission and make available
         to its securityholders, as soon as reasonably practicable, earnings
         statements (which need not be audited) covering a period of 12 months
         beginning within three months after the effective date of the
         Registration Statement, which earnings statements shall satisfy the
         provisions of Section 11(a) of the Securities Act; and

                          (xvi) use its best efforts to take all other steps
         necessary to effect the registration of, and maintain an effective
         Registration Statement with respect to, such Registrable Shares
         contemplated hereby.

                  (b) Each holder of the Registrable Shares, upon receipt of any
notice from the Company of any event of the kind described in Section 6(a)(viii)
hereof, shall forthwith discontinue disposition of the Registrable Shares
pursuant to the Registration Statement covering such Registrable Shares until
such holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 6(a)(viii) hereof, and, if so directed by the Company,
such holder shall deliver to the Company all copies, other than permanent file
copies then in such holder's possession, of the most recent Prospectus covering
such Registrable Shares at the time of receipt of such notice.

         SECTION 7. EXPENSES.

                  All expenses (other than underwriting discounts and
commissions relating to the Registrable Shares) incurred by the Company and the
Shareholders in complying with this Agreement, including, without limitation,
all registration and filing fees (including all expenses incident to filings
with the National Association of Securities Dealers, Inc.), fees and expenses of
complying with securities and blue sky laws, printing expenses, fees and
expenses of the Company's counsel and accountants and fees and expenses of the
Shareholders' Counsel, shall be paid by the Company in connection with
registrations requested under Section 2 or Section 4; provided, however, that
all underwriting discounts and selling commissions applicable to the Registrable
Shares and Other Shares shall be borne by the holders selling such Registrable
Shares and Other Shares, in proportion to the number of Registrable Shares and
Other Shares sold by each such holder.

         SECTION 8. INDEMNIFICATION.

                  (a) In connection with any registration of any Registrable
Shares under the Securities Act pursuant to this Agreement, the Company shall
indemnify and hold harmless, to the fullest extent permitted by law, each holder
of Registrable Shares, each underwriter, broker or any other Person acting on
behalf of the holders of Registrable Shares and each other Person, if any, who
controls any of the foregoing Persons within the meaning of the Securities Act
(each such indemnified Person being referred to herein as an "Indemnified
Person") against any losses, claims, damages or liabilities, joint or several
(or actions in respect thereof), to which any of the foregoing Persons may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities



                                       10
<PAGE>   13

(or actions in respect thereof) arise out of or are based upon an untrue
statement or allegedly untrue statement of a material fact contained in or
incorporated by reference in the Registration Statement under which such
Registrable Shares were registered under the Securities Act, any preliminary
Prospectus or final Prospectus contained therein or otherwise filed with the
Commission, any amendment or supplement thereto or any document incident to
registration or qualification of any Registrable Shares, or arise out of or are
based upon 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 or, with respect to any Prospectus, necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, or any violation by the Company of the Securities Act or state
securities or blue sky laws applicable to the Company and relating to action or
inaction required of the Company in connection with such registration or
qualification under such state securities or blue sky laws; and shall promptly
reimburse the Indemnified Persons for any legal or other expenses reasonably
incurred by any of them in connection with investigating or defending any such
loss, claim, damage, liability or action; provided, however, that the Company
shall not be liable in any such case to any such Indemnified Person to the
extent that any such loss, claim, damage, liability or action (including any
legal or other expenses incurred) arises out of or is based upon: (i) an untrue
statement or allegedly untrue statement or omission or alleged omission made in
said Registration Statement, preliminary Prospectus, final Prospectus,
amendment, supplement or document incident to registration or qualification of
any Registrable Shares in reliance upon and in conformity with written
information furnished to the Company through an instrument duly executed by such
Indemnified Person specifically for use in the preparation thereof or (ii) any
Indemnified Person's failure to deliver a copy of the Prospectus (including any
amendment or supplement thereto) after the Company has delivered to such
Indemnified Person a sufficient number of copies of the same.

                  (b) In connection with any registration of Registrable Shares
under the Securities Act pursuant to this Agreement, each holder of Registrable
Shares being registered shall, severally and not jointly, to the fullest extent
permitted by law, indemnify and hold harmless (in the same manner and to the
same extent as set forth in Section 8(a) above) the Company, each director of
the Company, each officer of the Company who shall have signed such Registration
Statement, each other holder of Registrable Shares or Other Shares, each agent,
underwriter, broker or other Person acting on behalf of the Company, each other
holder of Registrable Shares or Other Shares and each Person who controls any of
the foregoing Persons within the meaning of the Securities Act with respect to
any statement or omission from such Registration Statement, any preliminary
Prospectus or final Prospectus contained therein or otherwise filed with the
Commission, any amendment or supplement thereto or any document incident to
registration or qualification of any Registrable Shares, if such statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company or such underwriter through an instrument duly executed
by such holder specifically for use in connection with the preparation of such
Registration Statement, preliminary Prospectus, final Prospectus, amendment,
supplement or document; provided, however, that the



                                       11
<PAGE>   14

maximum amount of liability in respect of such indemnification shall be
limited, in the case of each seller of Registrable Shares, to an amount equal to
the net proceeds actually received by such seller from the sale of Registrable
Shares effected pursuant to such registration.

                  (c) Promptly after receipt by an indemnified party of notice
of the commencement of any action involving a claim referred to in Section 8(a)
or Section 8(b), such indemnified party will, if a claim in respect thereof is
made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the indemnified party's
failure to give such notice shall not release, relieve or in any way affect the
indemnifying party's obligation hereunder to indemnify the indemnified party
unless and to the extent that the rights of the indemnifying party are
prejudiced thereby. In case any such action is brought against an indemnified
party, the indemnifying party will be entitled to participate in and to assume
the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that he, she, or it may wish, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of his, her or its election so to assume the
defense thereof, the indemnifying party shall not be responsible for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof; provided, however, that if any indemnified party shall
have reasonably concluded (based on the written advice of counsel) that there
may be one or more legal or equitable defenses available to such indemnified
party which are additional to or conflict with those available to the
indemnifying party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this
Section 8, the indemnifying party shall not have the right to assume the defense
of such action on behalf of such indemnified party and such indemnifying party
shall reimburse such indemnified party and any Person controlling such
indemnified party for that portion of the fees and expenses of any counsel
retained by the indemnified party which is reasonably related to the matters
covered by the indemnity agreement provided in this Section 8.

                  (d) If the indemnification provided for in this Section 8 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, claim, damage, liability or action referred to
herein (other than as a result of the applicability of the proviso in Section
8(a)), then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amounts paid or payable by such
indemnified party as a result of such loss, claim, damage, liability or action
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 statements or omissions which resulted in such loss, claim,
damage, liability or action as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

         SECTION 9. UNDERWRITING AGREEMENT.

                  (a) If any registration pursuant to Section 2 or Section 4 is
requested to be an underwritten offering, the Company shall negotiate in good
faith to enter into a reasonable and customary underwriting agreement with the
underwriters thereof. The Company shall be entitled to receive indemnities from
lead institutions, underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the same
extent as provided above with respect to information so furnished in writing by
such Persons specifically for inclusion in any Prospectus or Registration
Statement and to the extent customary given their role in such distribution.

                  (b) No Shareholder may participate in any registration
hereunder that is underwritten unless such Shareholder agrees to (i) sell such
Shareholder's Registrable Shares proposed to be included therein on the basis
provided in any underwriting arrangements approved by the Company and a Majority
of Shareholders and (ii) as expeditiously as possible, notify the Company of the
occurrence of any event concerning such Shareholder as a result of which the
Prospectus relating to such registration 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 light of the circumstances under
which they were made, not misleading.

         SECTION 10. INFORMATION BY HOLDER.

                  The Shareholders shall furnish to the Company such written
information regarding the Shareholders and the distribution proposed by the
Shareholders as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Agreement.

         SECTION 11. EXCHANGE ACT COMPLIANCE.

                  From the Registration Date or such earlier date as a
Registration Statement filed by the Company pursuant to the Exchange Act
relating to any class of the Company's securities shall have become effective,
the Company shall comply with all of the reporting requirements of the Exchange
Act applicable to it (whether or not it shall be required to do so) and shall
comply with all other public information reporting requirements of the
Commission which are conditions to the availability of Rule 144 for the sale of
the Common Stock. The Company shall cooperate with the Shareholders in supplying
such information as may be necessary for the Shareholders to complete and file
any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

         SECTION 12. MERGERS, ETC.

                  The Company shall not, directly or indirectly, enter into any
merger, consolidation or reorganization in which the Company shall not be the
surviving



                                       13
<PAGE>   16

corporation unless the surviving corporation shall, prior to such merger,
consolidation or reorganization, agree in writing to assume the obligations of
the Company under this Agreement, and for that purpose references hereunder to
"Registrable Shares" shall be deemed to include the shares of common stock, if
any, or other securities that the Shareholders would be entitled to receive in
exchange for Common Stock under any such merger, consolidation or
reorganization; provided, however, that, to the extent the Shareholders receive
securities that are by their terms convertible into shares of common stock of
the issuer thereof, then any such shares of common stock as are issued or
issuable upon conversion of said convertible securities shall be included within
the definition of "Registrable Shares."

         SECTION 13. NEW CERTIFICATES.

                  As expeditiously as possible after the effectiveness of any
Registration Statement filed pursuant to this Agreement, the Company will
deliver in exchange for any legended certificate evidencing Registrable Shares
so registered, new stock certificates not bearing any restrictive legends.

         SECTION 14. NO CONFLICT OF RIGHTS; SELECTION OF UNDERWRITER.

                  The Company shall not, at any time after the date hereof,
grant any registration rights that conflict with or impair, or have any parity
with or priority over, the registration rights granted hereby. In any Public
Offering, the managing underwriter shall be a nationally recognized investment
banking firm chosen by the Board.

         SECTION 15. TERMINATION.

                  This Agreement shall terminate and be of no further force or
effect upon the written agreement of the Company, a majority of Registrable
Shares held by the Investors (which majority must include the affirmative vote
of all Registrable Shares then held by UBS) and a majority of Registrable Shares
held by the Continuing Shareholders or when there shall no longer be any
Restricted Shares outstanding.

         SECTION 16. MISCELLANEOUS.

                  (a) Successors and Assigns. Except as expressly set forth
herein, this Agreement shall bind and inure to the benefit of the Company and
the Shareholders and, subject to Section 16(b), the respective successors and
assigns of the Company and the Shareholders. This Agreement is not intended to
create any third party beneficiaries.

                  (b) Assignment. Each Shareholder may assign its rights
hereunder to any purchaser or transferee of Registrable Shares; provided,
however, that such purchaser or transferee shall, as a condition to the
effectiveness of such assignment, unless already a party to this Agreement, be
required to execute a counterpart to this Agreement agreeing to be treated as
Shareholder hereunder, whereupon such purchaser or transferee shall have the
benefits of and shall be subject to the restrictions contained in this Agreement
as if



                                       14
<PAGE>   17

such purchaser or transferee was originally included in the definition of a
Shareholder and had originally been a party hereto.

                  (c) Severability. It is the desire and intent of the parties
hereto that the provisions of this Agreement be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any particular provision of this
Agreement shall be adjudicated by a court of competent jurisdiction to be
invalid, prohibited or unenforceable for any reason, such provision, as to such
jurisdiction, shall be ineffective, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of this
Agreement or affecting the validity or enforceability of such provision in any
other jurisdiction. Notwithstanding the foregoing, if such provision could be
more narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.

                  (d) Entire Agreement. This Agreement and the other writings
referred to herein or delivered pursuant hereto contain the entire agreement
among the parties with respect to the subject matter hereof and thereof and
supersede all prior and contemporaneous arrangements or understandings with
respect hereto and thereto.

failure of any party to enforce any of the provisions of this Agreement shall in
no way be construed as a waiver of such provisions and shall not affect the

of counterparts, and each such counterpart hereof shall be deemed to be an
