                            SHAREHOLDERS' AGREEMENT

     This Amended and Restated Shareholders' Agreement (the "Restated
Shareholders' Agreement") is made as of December 29, 1995 and amends and

of securities by any Purchasers (as those terms are defined in the Series A
Agreement).

     B.     On August 31, 1992, the Company and certain securityholders of the
Company entered into a Series B Preferred Stock Purchase Agreement (the "Series

granted in the Series A Agreement.

Company entered into a Series B Preferred Stock and Warrant Purchase Agreement
(the "Second Series B Agreement"), which, among other things, conferred upon

COSMAT Warrant would be deemed "Registrable Securities" under Section 8 of the 
Series B Agreement.
 
     E.     On March 10, 1994, in connection with the Note and Warrant Purchase
Agreement, the Company issued Warrants to purchase Common Stock (the "First
Bridge Warrants"); and the Company and certain parties to the Second Series B
Agreement, as amended, entered into a new agreement (the "Registration Rights
Agreement"), which superseded Section 8 of the Second Series B Agreement, as
amended by the Series B Amendment, in its entirety, contained provisions
substantially similar to those of Section 8 of the Second Series B Agreement, as
amended by the Series B Amendment, and granted such rights to the holders of
First Bridge Warrants.

     F.     On June 20, 1994, the Company granted to Silicon Valley Bank ("SVB")
and Hambrecht & Quist Guaranty Finance ("H&Q") warrants to purchase Common Stock
of the Company (the "SVB/H&Q Warrants"), and in connection therewith, the

"Series C Preferred") and warrants to purchase Series C Preferred Stock (the
"Series C Warrants") pursuant to the Series C Preferred Stock Purchase Agreement
dated September 29, 1994 (the "Series C Agreement"), certain shareholders
constituting the holders of a majority of the Registrable Securities (as that
term is defined in the Registration Rights Agreement, as amended) entered into
the Shareholders' Agreement which restated and superseded the Registration
Rights Agreement, in its entirety, and which granted such registration rights to
the holders of the Series C Preferred and Series C Warrants.

     I.     On May 16, 1995, the Company granted Silicon Valley Bank warrants to
purchase Common Stock of the Company (the "SVB Warrants"), and in connection
therewith, the Company and certain parties to the Shareholders' Agreement
entered into the First Amendment to Shareholders' Agreement (the "First
Amendment") which provided that the shares of Common Stock issuable upon
exercise of the SVB Warrants would be deemed registerable securities under the
Shareholders' Agreement.

Agreement entered into the Second Amendment to Shareholders' Agreement (the
"Second Amendment") which provided that the shares of Common Stock issuable upon
exercise of the Common Warrants would be deemed registerable securities under
the Shareholders' Agreement.

     K.     In connection with the issuance of Series D Preferred Stock (the
"Series D Preferred Stock") pursuant to the Series D Preferred Stock Purchase
Agreement dated December ___, 1995 (the "Series D Agreement"), the purchasers of
the Series D Preferred Stock (the "Series D Holders") desire to enter into an
agreement which will restate and supersede the Shareholders' Agreement, in its
entirety, and which will grant certain rights to the Series D Holders.

     1.2    Requested Registration.
            ---------------------- 

            (a)  Request for Registration.  In case the Company shall receive
                 ------------------------
from Initiating Holders a written request six (6) months after the effective
date of the initial registration of the Company's securities, that the Company
effect any underwritten registration, qualification, or compliance with respect
to Registrable Securities held by such Initiating Holders, then the Company
shall:

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

                   (ii)  as soon as practicable, use its most diligent efforts
to effect all such registration, qualification, or compliance (including,
without limitation, the execution of an undertaking to file post-effective
amendments, appropriate qualification under applicable blue sky or other state
securities laws, and appropriate compliance with applicable regulations issued
under the Securities Act and any other governmental requirements or regulations)
as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any Holders joining in such request as are specified in a written
request received by the Company within twenty (20) days after the date the
Company mails such written notice;

                 Provided, however, that the Company shall not be obligated to
take any action to effect any such registration, qualification, or compliance
pursuant to this Section 1.2:

                         (A)  In any jurisdiction in which the Company would be
required to execute a general consent to service of process in effecting such
registration, qualification, or compli ance unless the Company is already
subject to service in such jurisdiction and except as may be required by the
Securities Act;

                                      -5-

 
                         (B)  During the period starting with the date sixty
(60) days prior to the Company's estimated date of filing of, and ending on the
date six months immediately following the effective date of any registration
statement pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit plan
or initiated by security holders);

                         (C)  Unless the registration will be requested for at
least ten percent (10%) of the Registrable Securities; or

                         (D)  At any time during which the Company is qualified
to use Form S-3 for registration of the Registrable Securities held by the
Holders.

                 Subject to the foregoing clauses (A) through (D), the Company
shall file a registration statement covering the Registrable Securities so
requested to be registered as soon as prac ticable, and in any event within 90
days, after receipt of the request or requests of the Initiating Holders;
provided, however, that if the Company shall furnish to Holders requesting a
registration statement under this Section 1.2, a certificate signed by the
President of the Company stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its shareholders for such registration statement to be filed and it is therefore
essential to defer the filing of such registration statement, the Company shall
have the right to defer such filing for a period of not more than ninety (90)
days after receipt of the request of the Initiating Holders; provided further,
that the Company may not utilize this right more than once in any twelve- (12-)
month period.

            (b)  Underwriting.  The right of any Holder to registration pursuant
                 ------------
to this Section 1.2 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting to the extent requested (unless otherwise mutually agreed by a
majority in interest of the Initiating Holders and such Holder) and to the
extent provided herein.

                 The Company shall (together with all Holders and holders of
other securities proposing to distribute their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by a majority in interest of
the Initiating Holders. Notwithstanding any other provision of this Section 1.2,
if the managing underwriter advises the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the securities of the Company entitled to be included in such
registration which are not Registrable Securities shall be excluded from such
registration to the extent required by such limitation. If a limitation of the
number of shares is still required, then the Company shall so advise all
Holders, and the number of shares of Registrable Securities that may be included
in the registration and underwriting shall first be allocated among Holders
thereof in proportion, as nearly as practicable, to the respective amounts of
Registrable Securities, other than Founders Shares, entitled to inclusion
(determined without regard to any require-

                                      -6-

 
ment of a request to be included in such registration) in such registration held
by all such Holders at the time of filing the registration statement and,
second, should the underwriter's limitation permit inclusion of any additional
securities, among all Holders in proportion, as nearly as practicable, to the
respective amounts of Founders Shares entitled to inclusion (determined without
regard to any requirement of a request to be included in such registration) in
such registration held by all such Holders at the time of filing the
registration statement. No Registrable Securities or other securities excluded
from the underwriting by reason of the underwriter's marketing limitation shall
be included in such registration. To facilitate the allocation of shares in
accordance with the above provisions, the Company or the underwriters may round
the number of shares allocated to any Holder to the nearest 100 shares.

                 If any Holder of Registrable Securities disapproves of the
terms of the underwriting, such person may elect to withdraw therefrom by
written notice to the Company, the managing underwriter and the Initiating
Holders. The Registrable Securities and/or other securities so withdrawn shall
also be withdrawn from registration, and such Registrable Securities shall not
be trans ferred in a public distribution prior to ninety (90) days after the
effective date of such registration, or such other shorter period of time as the
underwriters may require. If by the withdrawal of such Registrable Securities a
greater number of Registrable Securities held by other Holders may be included
in such regis tration (up to the maximum of any limitation imposed by the
underwriters), then the Company shall offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion and manner used in determining the
underwriter limitation in this Section 1.2(b).

                 If the managing underwriter has not limited the number of
Registrable Securities to be underwritten, the Company may include securities
for its own account or for the account of others in such registration if the
underwriter so agrees and if the number of Registrable Securities which would
otherwise have been included in such registration and underwriting will not
thereby be limited.

     1.3    Company Registration.
            -------------------- 

            (a)  Notice of Registration.  If at any time or from time to time,
                 ----------------------
the Company shall determine to register any of its securities, either for its
own account or the account of a security holder or holders exercising their
respective demand registration rights, other than (i) a registration relating
solely to employee benefit plans, or (ii) a registration relating solely to a
Rule 145 transaction, the Company shall:

                 (i)    promptly give to each Holder 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 the Registrable Securities 

                                      -7-

 
specified in a written request by each Holder received by the Company within
fifteen (15) days after the Company mails such written notice, subject to the
provisions below.
 
            (b)  Underwriting.  The right of any Holder to registration pursuant
                 ------------
to Section 1.3 shall be conditioned upon the participation by such Holder in
such underwriting, if any, and the inclusion of the Registrable Securities of
such Holder in the underwriting to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall
(together with the Company and the other holders distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the managing underwriter selected for such underwriting by the
Company. Notwithstanding any other provision of this Section 1.3, if the
managing underwriter deter mines that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit the
Registrable Securities held by Holders. If a limitation of the number of shares
to be included in such registration is required, then the Company shall so
advise all Holders, and the number of shares of Registrable Securities and other
securities that may be included in the registration and underwriting shall be
allocated among all Holders and other holders of securities thereof: first,
among all Holders of the Common Warrants in proportion as nearly as practicable,
to the respective amounts of securities entitled to inclusion (determined
without regard to any requirement of a request to be included in such
registration) in such registration held by all such Holders at the time of
filing the registration statement; second, should the underwriter's limitation
permit inclusion of any additional securities, among all remaining Holders and
other holders in proportion, as nearly as practicable, to the respective amounts
of securities, other than Founders Shares, entitled to inclusion (determined
without regard to any requirement of a request to be included in such
registration) in such registration held by all such remaining Holders and other
holders at the time of filing the registration statement; and third, should the
underwriter's limitation permit inclusion of any additional securities, among
all Holders in proportion, as nearly as practicable, to the respective amounts
of Founders Shares entitled to inclusion (determined without regard to any
requirement of a request to be included in such registration) in such
registration held by all such Holders at the time of filing the registration
statement; provided, however, that the number of Registrable Securities entitled
to inclusion in any such registration, except for the registration of the
initial public offering of the Company's securities, shall be no less than
twenty percent (20%) of the total number of shares covered by such registration.
To facilitate the allocation of shares in accor dance with the above provisions,
the Company may round the number of shares allocated to any Holder to the
nearest 100 shares. If any Holder or other holder disapproves of the terms of
any such under writing, he may elect to withdraw therefrom by written notice to
the Company and the managing underwriter. Any securities excluded or withdrawn
from such underwriting shall be withdrawn from such registration.

            (c)  Right to Terminate Registration.  The Company shall have the
                 -------------------------------
right to terminate or withdraw any registration initiated by it under this
Section 1.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration.

                                      -8-

 
     1.4    Form S-3 Registration.  In case the Company shall receive from a
            ---------------------                                           
Holder or Holders a written request that the Company effect a registration on
Form S-3 and any related qualification or compliance with respect to an amount
of the Registrable Securities owned by such Holder or Holders for which the
anticipated aggregate offering price would be at least $500,000, the Company
shall:

            (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 or 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 given within
twenty (20) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification, or compliance pursuant to this Section 1.4: (1) if
Form S-3 is not available for such offering by the Holders; (2) if the Company
shall furnish to the Holders a certificate signed by the president of the
Company stating that in the good faith judgment of the board of directors of the
Company, it would be seriously detrimental to the Company and its shareholders
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 ninety (90) days after receipt of the
initiating request of the Holder or Holders under this Section 1.4; provided,
however, that the Company shall not utilize this right more than twice in any
twelve- (12-) month period; (3) if the Company has, within the twelve- (12-)
month period preceding the date of such request, already effected one (1)
registration on Form S-3 for the Holders pursuant to this Section 1.4; or (4) in
any jurisdiction in which the Company would be required to execute a general
consent to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction
and except as may be required by the Securities Act.

                 Subject to the foregoing, the Company shall effect such
registration, qualification, or compliance (including, without limitation, the
execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act and any other governmental requirements or regulations) covering the
Registrable Securities and other securities so requested to be registered as
soon as practicable after receipt of the request or requests of the Holders.
Registrations effected pursuant to this Section 1.4 shall not be counted as
demands for registration or registrations effected pursuant to Sections 1.2 or
1.3.

                 If the registration to be effected pursuant to this Section 1.4
is to be an underwritten public offering, it shall be managed by an underwriter
or underwriters acceptable to the Company selected by a majority in interest of
the Holders requesting registration. In such event, the right of any Holder to
registration pursuant to Section 1.4 shall be conditioned upon the participation

                                      -9-

 
by such Holder in such underwriting and the inclusion of the Registrable
Securities of such Holder in the underwriting to the extent provided herein. If
the managing underwriter so selected determines that marketing factors require a
limitation of the number of shares to be underwritten, the managing underwriter
may limit the Registrable Securities held by such Holders to be included in such
registration. The Company shall so advise such Holders, and the number of shares
of Registrable Securities that may be included in the registration shall be
allocated among such Holders in proportion to the respective amounts of
Registrable Securities which would be held by each of such Holders at the time
of filing of the registration statement. Any Registrable Securities that are so

throughout this Section the term "Form S-3" shall be deemed to include any
equivalent successor form for registration pursuant to the Act.

     1.5    Expenses of Registration.
            ------------------------ 

            All Registration Expenses incurred in connection with the
registration, qualification or compliance pursuant to Sections 1.2, 1.3, and 1.4
shall be borne by the Company; provided, however, that the Company shall not be
required to pay for expenses of (i) any registrations requested pursuant to
Section 1.2 after the Company has effected three (3) such registrations pursuant
to Section 1.2 or 1.4 and such registrations have been declared or ordered
effective, and (ii) any registration proceeding begun pursuant to Section 1.2,
the request of which has been subsequently withdrawn by the Initiating Holders,
in which case such expenses shall be borne by the Holders of securities
(including Registrable Securities) pro rata in accordance with the number of
shares initially sought to be registered requesting or causing such withdrawal,
unless the Holders shall agree that such withdrawn registration shall be counted
as a registration for purposes of Section 1.2(a)(ii)(D). Notwithstanding the
foregoing, if such withdrawal is occasioned by the disclosure to the Initiating
Holders of a material adverse fact regarding the Company not known by the
Initiating Holders at the time of their request for registration then the
Company will bear such Registration Expenses and the Holders will retain their
rights under Section 1.2 hereof.

     1.6    Registration Procedures.  If and whenever the Company is required by
            -----------------------                                             
the provisions of this Section to use its most diligent efforts to effect
promptly the registration of Registrable Securities, the Company shall:

            (a)  Prepare and file with the Commission a registration statement
with respect to such Registrable Securities and use its most diligent efforts to
cause such registration statement to become and remain effective as provided
herein.

            (b)  Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
current and to comply with the provisions of the Securities Act with respect to
the sale or other disposition of all Registrable Securities covered by such
registration statement, including such amendments and supplements as may be
necessary to reflect the 

                                      -10-

 
intended method of disposition of the prospective seller or sellers of such
Registrable Securities, but for no longer than one hundred twenty (120) days
subsequent to the effective date of such registration in the case of a
registration statement on Form S-1 (or any similar form of registration
statement required to set forth substantially identical information) and for no
longer than 90 days in the case of a registration statement on Form S-3.

            (c)  Furnish to each prospective seller of Registrable Securities
such number of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other
documents, as such seller may reasonably request in order to facilitate the
public sale or other disposition of the Registrable Securities of such seller.

     1.7    Indemnification.  In the event any of the Registrable Securities are
            ---------------                                                     
included in a registration statement under this Section:

            (a)  The Company will indemnify each Holder, each of its officers
and directors and partners and such Holder's separate legal counsel and
independent accountants, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, and each underwriter, if any, and
each person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages or liabilities (or
actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading, or any violation by the Company of any rule or
regulation promulgated under the Securities Act applicable to the Company in
connection with any such registration, qualification or compliance, and the
Company will reimburse each such Holder, each of its officers and directors and
partners and such Holders' separate legal counsel and independent accountants
and each person controlling such Holder, each such underwriter and each person
who controls any such underwriter, for any legal and any other expenses
reasonably incurred in connection with investigating, preparing or defending any
such claim, loss, damage, liability or action, provided that the Company will
not be liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission or alleged untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder or underwriter and stated to be specifically for
use therein.

            (b)  Each Holder will, if Registrable Securities held by such Holder
are included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers and its legal counsel and independent accountants, each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, 

                                      -11-

 
and each other such Holder, each of its officers and directors and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, 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, and will reimburse the
Company, such Holders, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
(which information shall be limited to a brief description of the Holder, its
holdings of the Registrable Securities to be sold, and its plan of distribution
therefor) furnished to the Company by an instrument duly executed by such Holder
and stated to be specifically for use therein; provided, however, that the
obligations of each Holder hereunder shall be limited to an amount equal to the
net proceeds to each such Holder of Registrable Securities sold pursuant to such
registration statement.

            (c)  Each party entitled to indemnification under this Section (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

            (d)  If the indemnification provided for in this Section is held by
a court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage or expense referred to herein,
then the Indemnifying Party, in lieu of indemnifying the Indemnified Party,
shall contribute to the amount paid or payable by such Indemnified Party with
respect to such loss, liability, claim, damage or expense in the proportion that
is appropriate to reflect the relative fault of the Indemnifying Party and the
Indemnified Party in connection with the statements or omissions that resulted
in such loss, liability, claim, damage or expense, as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of material fact or the 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; provided, however,

                                      -12-

 
that the obligations of each Holder to make contributions shall be limited to an
amount equal to the net proceeds received by each such Holder of Registerable
Securities sold pursuant to such registration statement.

            (e)  The indemnity and contribution provided by each Holder of
Registrable Securities under this Section 1.7 shall be provided severally and
not either jointly or jointly and severally with any other Holder.

            ---------------------                                       
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Section.

     1.9    Rule 144 Reporting.  With a view to making available the benefits

any time after it has become subject to such reporting requirements), a copy of
the most recent annual or quarterly report of the Company, and such other
reports and documents of the Company and other information in the possession of

outstanding Registrable Securities, enter into any agreement with any holder or
prospective holder of any securities of the Company which would allow such
holder or prospective holder (a) to include such securities in any registration
filed under Section 1.2 hereof, unless under the terms of such agreement, such
holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of his securities will not
reduce the amount of the Registrable Securities of the Holders which is
included, or (b) to make a demand registration which could result in such
registration statement being declared effective prior to the earlier of either
of the dates set forth in subsection 1.2(a) or within one hundred twenty (120)
days of the effective date of any registration effected pursuant to Section 1.2.

     1.12   Amendment of Registration Rights.  The registration rights
            --------------------------------

            ----------------------------------

     1.14   Lock-Up Provision.  If requested by the Company and an
            -----------------                                     
underwriter of securities of the Company, no Holder shall sell or otherwise
transfer or dispose of any Restricted Securities (other than those securities

            --------------------------------------                    
Company is obligated to register securities pursuant to this Section 1, such
obligation may be satisfied, at the Company's option, by effecting a
registration in a jurisdiction other than the United States, pursuant to the
applicable securities laws of such jurisdiction. In the event the Company
effects a registration in a foreign jurisdiction, provided that in the good
faith judgment of the board of directors of the Company registration in such
jurisdiction is in the best interests of the Company and its shareholders, and
the Holders will not be materially adversely affected by such choice of
jurisdiction, (i) the rights of holders of Registrable Securities pursuant to
Section 1.3 hereof shall apply to such registration, and (ii) references in this
Section 1 to laws, rules, and customary practices applicable to a registration

Registration Rights Agreement, as amended) hereby agree that the execution and
delivery of this Restated Shareholders' Agreement is an amendment of the
Registration Rights Agreement, as amended, and that the registration rights
contained therein shall be null and void as of the execution hereof and shall be
superseded in their entirety by the terms of this Restated Shareholders'
Agreement.

directors (resulting in a board of nine (9) directors) if the Company fails to
meet any one or more of the following three criteria for the period (the
"Relevant Period") commencing on the date hereof and ending December 31, 1996:

Company's first offering of voting equity securities to the public pursuant to a
registration statement filed with the Securities and Exchange Commission. If

            --------------------                                            
Section 4.1 above:

            (a)  Prior to any transfer of the Company's securities, the
Transferring Shareholder (the "Transferring Shareholder") shall promptly notify
the Company and all holders of Series C and Series D Preferred Stock (not
including the Transferring Shareholder) (the "Remaining Holders") of the terms
and conditions of such purchase offer (the "Purchase Offer"). Such notice shall
set forth (a) the Transferring Shareholder's bona fide intention to transfer
such securities; (b) the securities to be transferred; and (c) the cash price
or, in reasonable detail, other consideration, per share for which the
Transferring Shareholder proposes to transfer such securities.

            (b)  For twenty (20) days following receipt of such notice, the
Company shall have the option to purchase all or any portion of the securities
specified in the notice upon the terms specified in the Purchase Offer. If the
Company elects to purchase any of the securities specified in the notice, the
Company will deliver written notice to the Transferring Shareholder. Settlement
for the purchase of the securities shall be made as provided below.

            (c)  In the event the Company does not elect to acquire all of the
securities specified in the Purchase Offer, the Company shall so notify the
Remaining Holders who at such time shall have the option to purchase such
securities on a pro rata basis determined by applying (i) the ratio of the
number of shares of Common Stock held by each Remaining Holder as of the date of
the notice to the number of shares of Common Stock held by the Remaining Holders
in aggregate, assuming the conversion of all Preferred Stock in both cases, to
(ii) the number of securities available through the Purchase Offer, provided
that the securities allocated to any Remaining Holder that does not elect to
acquire the securities shall be allocated pro rata to those that do elect. If
any Remaining Holder elects to purchase any of the remaining securities
specified in the notice, such Remaining Holder shall deliver written notice to
the Transferring Shareholder and the Company. Settlement for the purchase of the
securities shall be made as provided below.

            (d)  In the event the Remaining Holders elect not to purchase all of
the remaining securities specified in the Transferring Shareholder's notice, the
Transferring Shareholder may sell to any transferee (subject to Sections 4.1 and
4.2 above) on the terms of the Purchase Offer the remainder of the securities
specified in the notice provided that such sale closes within sixty (60) days of
the expiration of the Remaining Holders' twenty (20) day notice period and that
the sale is on terms substantially similar to those specified in the
Transferring Shareholder's notice.

                                      -19-

 
            (e)  Settlement for any or all of the securities elected to purchase
under this Section 4 shall be made in cash within five (5) business days after
the Transferring Shareholder receives the notice from the Company or the
Remaining Holders that it is electing to purchase some or all of the securities;
provided, however, that if the terms of the Purchase Offer called for payment
other than in cash, the Company or the Remaining Holders shall pay for such
securities on the same terms and conditions set forth in the Transferring
Shareholders' notice.

            (f)  Any sale or transfer, or purported sale or transfer, of the
Company's securities shall be null and void unless the terms, conditions and
provisions of this Section 4 are strictly observed and followed. The Company
will not be required (i) to transfer on its books any shares that have been
sold, gifted or otherwise transferred in violation of this Restated
Shareholders' Agreement, or (ii) to treat as owner of such shares, or to accord
the right to vote or pay dividends to any purchaser, donee or other transferee
to whom such shares may have been so transferred.

            (g)  Each certificate representing securities now or hereafter owned
by the Shareholders or issued to any permitted transferee shall be endorsed with
the following legend or its substantial equivalent:

     "THE SALE OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS
     SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF FIRST OFFER
     COPIES OF WHICH MAY BE OBTAINED WITHOUT CHARGE UPON WRITTEN REQUEST TO THE
     SECRETARY OF THE CORPORATION."

            (h)  The legend shall be removed and the right of first offer shall
terminate immediately prior to the closing of the sale of the Company's Common
Stock in a bonafide underwritten public offering registered under the Act.

     4.4    Permitted Transfers.  The transfer restrictions and rights of first
            -------------------

pertain or apply to (i) any transfer to the spouse or to a trust for the benefit
of the Transferring Shareholder or his or her spouse, brother(s), sister(s),
ancestors, descendants, in any combination, (ii) any sale of securities pursuant
to any exercise of regis tration rights as set forth in Section 1 of this
Restated Shareholders' Agreement, (iii) any affiliates of the Transferring
Shareholder, or (iv) any distribution to the partners of a Transferring
Shareholder which is a limited partnership, which distribution is consistent
with the terms of such limited partnership agreement; provided that (A) the
Transferring Shareholder shall inform the Company and Remaining Holders of such
transfer prior to effecting it and (B) except for Section 4.4(ii), the
transferee (the "Permitted Transferee") shall furnish the Company with a written
agreement to be bound by and comply with all provisions of this Restated
Shareholders' Agreement applicable to the shareholder.
