the Prior Rights Agreement is hereby amended and restated to read in its 
entirety as set forth herein.
 
     2.   Registration.  
          ------------
 
          2.1  Definitions. As used herein, the following terms, have the 
               ----------- 
following meanings:

               (a) "Forms S-1," "S-2"  and "S-3:"  The forms so designated,
promulgated by the Commission for registration of securities under the
Securities Act of 1933, as amended (the "Securities Act"), and any forms
succeeding to the functions of such forms, whether or not bearing the same
designation.

               (b) "Commission:"  The Securities and Exchange Commission or any
other federal agency at the time administering the Securities Act.

               (c) "Holder:"  A holder of Registrable Stock, provided that
anyone who acquires any Registrable Stock in a distribution pursuant to a
registration statement filed by the Company under the Securities Act shall not
thereby be deemed to be a "Holder."

               (d) "Register," "registered" and "registration" refer to a
registration effected by filing a registration statement in compliance with the
Securities Act, and the declaration or ordering by the Commission of
effectiveness of such registration statement.

               (e)  "Registrable Stock:"

                    (i)   the shares of Common Stock issuable or issued upon
conversion of the Series A Shares,

                    (ii)  The shares of Common Stock issuable or issued upon
conversion of the Series B Shares,

                    (iii) The shares of Common Stock issuable or issued upon
conversion of the Series C Shares,

                                      -2-

 
                    (iv)  the shares of Common Stock issuable or issued upon
conversion of the Warrant Shares (the shares of Common Stock referred to in
clauses (i), (ii), (iii), (iv) and (v) hereof are collectively referred to
hereafter as the "Stock"), and

                    (v)   any other shares of Common Stock of the Company
issued as (or issuable upon the conversion or exercise of any warrant, right
or other security which is issued as) a dividend or other distribution with
respect to, or in exchange for or in replacement of, the Stock, excluding in
all cases, however, any Registrable Securities sold by a person in a
transaction in which his or her rights under this Agreement are not assigned;

provided, however, that Common Stock or other securities shall only be treated
- --------  -------                                                             
as Registrable Stock if and so long as they have not been (A) sold to or through
a broker or dealer or underwriter in a public distribution or a public
securities transaction, or (B) sold in a transaction exempt from the
registration and prospectus delivery requirements of the Securities Act under
Section 4(1) thereof so that all transfer restrictions, and restrictive legends
with respect thereto, if any, are removed upon the consummation of such sale.

          2.2  Required Registration.
               --------------------- 

               (a) If the Holder or Holders of an aggregate of at least fifty
percent (50%) of the Registrable Stock propose to dispose of their Registrable
Stock (such Holder or Holders being herein called the "Initiating Holders"), the
Initiating Holders may request the Company in writing to effect such
registration, stating the number of shares of Registrable Stock to be disposed
of by such Initiating Holders and the intended method of disposition, including,
but not limited to, registration on Form S-1. Upon receipt of such request, the
Company shall give prompt written notice thereof to all other Holders, whereupon
such other Holders shall give written notice to the Company within 20 days after
the date of the Company's notice (the "Notice Period") if they propose to
dispose of any shares of Registrable Stock pursuant to such registration,
stating the number of shares of Registrable Stock to be disposed of by such
Holder or Holders and the intended method of disposition.

               (b) The Company will use its best efforts to effect promptly
after the Notice Period the registration under the Securities Act of all
shares of Registrable Stock specified in the requests of the Initiating
Holders and the requests of the other Holders subject, however, to the
limitations set forth in Section 2.4.

          2.3  Registration Procedures.  Whenever the Company is required by 
               ----------------------- 
the provisions of this Section 2 to use its best efforts to effect promptly 
the registration of shares of Registrable Stock, the Company will:

               (a) prepare and file with the Commission a registration
statement with respect to such shares and use its best 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 

                                      -3-

 
necessary to keep such registration statement effective and current and to
comply with the provisions of the Securities Act with respect to the
disposition of all shares covered by such registration statement, including
such amendments and supplements as may be necessary to reflect the intended
method of disposition from time to time of the prospective seller or sellers
of such shares, 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 S-2 and for no longer than ninety (90)
days in the case of a registration statement on Form S-3;

               (c) furnish to each prospective seller 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 shares owned by such seller;

               (d) use its best efforts to register or qualify the shares
covered by such registration statement under such other securities or blue sky
or other applicable laws of such jurisdiction within the United States as each
prospective seller shall reasonably request, to enable such seller to
consummate the public sale or other disposition in such jurisdictions of the
shares owned by such seller; provided, however, that in no event shall the
Company be obligated to qualify to do business in any jurisdiction where it is
not at the time so qualified or to take any action which would subject it to
service of process in suits other than those arising out of the offer or sale
of the Registrable Stock covered by such registration statement in any
jurisdiction where it is not at the time so subject; and

               (e) furnish to each prospective seller, to the extent requested
by such seller, a signed counterpart, addressed to the prospective sellers, of
(i) an opinion of counsel for the Company, dated the closing date of the sale
of the applicable Registrable Stock, and (ii) a "comfort" letter signed by the
independent public accountants who have certified the Company's financial
statements included in the registration statement, covering substantially the
same matters with respect to the registration statement (and the prospectus
included therein) and (in the case of the "comfort" letter) with respect to
events subsequent to the date of the financial statements, as are customarily
covered in opinions of issuer's counsel and in "comfort" letters delivered to
the underwriters in underwritten public offerings of securities.

          2.4  Limitations on Required Registrations.
               ------------------------------------- 

               (a) The Company shall not be required to effect more than two
registrations pursuant to Section 2.2.  The Company shall not be required to
effect any registration unless the anticipated aggregate offering price, net of
underwriting discounts and commissions, would exceed $2,000,000.

               (b) The Company shall not be required to cause a registration
requested pursuant to Section 2.2 to become effective prior to the earlier of
(i) three years after the date of the first closing under the Series C Purchase
Agreement or (ii) six (6) months after the Company's initial registration with
the Commission (other than a registration effected solely to implement an
employee benefit plan or a transaction to which Rule 145 of the Commission is
applicable).

                                      -4-

 
               (c) The Company shall not register securities for sale for its
own account or for the account of holders of securities other than Registrable
Stock in any registration requested pursuant to Section 2.2 without the
written consent of Initiating Holders who hold at least 51% of the Registrable
Stock as to which registration has been requested, unless such securities are
entitled to be included in such registration only to the extent that the
inclusion of such securities will not diminish the amount of Registrable Stock
included in such registration or otherwise materially and adversely affect the
right of the Initiating Holders to have their Registrable Securities
registered. The Company may not cause any other registration of securities for
sale for its own account (other than a transaction to which Rule 145 of the
Commission is applicable or a registration effected solely to implement an
employee benefit plan) to be initiated after a registration requested pursuant
to Section 2.2 and to become effective less than 90 days after the effective
date of any registration requested pursuant to Section 2.2.

               (d) Whenever a requested registration is for an underwritten
offering, only shares which are to be included in the underwriting may be
included in the registration. Notwithstanding the provisions of Sections
2.2(b) and 2.4(c), if the underwriter determines that (i) marketing factors
require a limitation of the total number of shares to be underwritten, or (ii)
the offering price per share would be reduced by the inclusion of the shares
of the Company or others, then the number of shares to be included in the
registration and underwriting shall first be allocated among all Holders who
indicated to the Company their decision to distribute any of their Registrable
Stock through such underwriting, in proportion, as nearly as practicable, to
the respective numbers of shares of Registrable Stock owned by such Holders at
the time of filing the registration statement, then, if any, to the Company
and others. No stock excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration. If
the Company disapproves of any such underwriting, the Company may elect to
withdraw therefrom by written notice to the Initiating Holders and the
underwriter. The securities so withdrawn from such underwriting shall also be
withdrawn from such registration.

               (e) If at the time of any request to register Registrable Stock
pursuant to Section 2.2 hereof, the Company is engaged, or has fixed plans to
engage within 90 days of the time of the request, in a registered public
offering as to which the Holders may include Registrable Stock pursuant to
Section 2.5 hereof or the Company is engaged in any other activity which, in the
good faith determination of the Board, would be adversely affected by the
requested registration to the material detriment of the Company, then the
Company may at its option direct that such request be delayed for a period not
in excess of 120 days from the effective date of such offering, or the date of
commencement of such other material activity, as the case may be, such right to
delay a request to be exercised by the Company not more than once in any 12-
month period while the rights set forth in Section 2.2 are in effect.

          2.5  Incidental Registration.  If the Company at any time proposes
               -----------------------                                         
to register any of its Common Stock under the Securities Act (other than a
registration effected solely to implement an employee benefit plan or a
transaction to which Rule 145 of the Commission is applicable), it will each
such time give written notice to all Holders of its intention so to do.  Upon
the written request of a Holder or Holders given within 20 days after receipt of
any such notice (stating the number of shares of Registrable Stock to be
disposed of by such Holder or Holders and the intended method of disposition),
the Company will use its best efforts 

                                      -5-

 
to cause all such shares intended to be disposed of, which the Holders shall
have requested registration thereof, to be registered under the Securities Act
so as to permit the disposition (in accordance with the methods in said
request) by such Holder or Holders of the shares so registered, subject,
however, to the limitations set forth in Section 2.6.

          2.6  Limitations on Incidental Registration.  If the registration
               --------------------------------------                         
of which the Company gives notice pursuant to Section 2.5 is for an underwritten
offering, only securities which are to be included in the underwriting may be
included in the registration.  Notwithstanding any provision of Section 2.5, if
the underwriter determines that marketing factors require a limitation of the
number of shares to be underwritten, the underwriter may exclude or otherwise
limit the number of shares, including Registrable Stock, requested to be
included in the registration and underwriting to a number of shares not less
than twenty percent (20%) of the aggregate number of shares to be disposed of in
the registration and underwriting, unless the registration is for an initial
public offering (in which case the percentage may be less).  The Company shall
so advise all Holders of any limitation (except those Holders who have not
indicated to the Company their decision to distribute any of their Registrable
Stock through such underwriting), and the number of shares, including
Registrable Stock, that may be included in the registration and underwriting
shall be allocated among the selling shareholders in proportion, as nearly as
practicable, to the respective amounts of securities, including Registrable
Stock, owned by such Holders and other selling shareholders entitled to be
included therein at the time of filing the registration statement, in accordance
with Section 2.12(a).  No Registrable Stock excluded from the underwriting by
reason of the underwriter's marketing limitation shall be included in such
registration.  If any Holder disapproves of any such underwriting, such person
may elect to withdraw therefrom by written notice to the Company and the
underwriter.  The Registrable Stock and/or other securities so withdrawn from
such underwriting shall also be withdrawn from such registration.

               The registration rights granted under Sections 2.2, 2.5 and 2.8
shall terminate as to any Holder or permissible transferee or assignee of such
rights if such person (a) holds one percent (1%) or less of the outstanding
shares of Common Stock of the Company (on an as-converted basis) and (b) is
permitted to sell all of the Registrable Stock held by him or her in a single
transaction to the public pursuant to Rule 144.

          2.7  Designation of Underwriter.
               -------------------------- 

               (a) In the case of any registration effected pursuant to
Section 2.2 or Section 2.8, a majority in interest of the requesting Holders
shall have the right to designate the managing underwriter in any underwritten
offering, which underwriter shall be reasonably acceptable to the Company.

               (b) In the case of any registration initiated by the Company,
the Company shall have the right to designate the managing underwriter in any
underwritten offering.

                                      -6-

 
          2.8  Form S-3.  The Company shall register its Common Stock under
               --------                                                       
the Securities Exchange Act of 1934, as amended, as promptly as reasonably
practicable following the effective date of the first registration of any
securities of the Company on Form S-1 and the Company shall thereafter effect
all qualifications and compliances as would permit or facilitate the sale and
distribution of its stock on Form S-3, to the extent available.  After the
Company has qualified for the use of Form S-3, the Holders shall have the right
to request an unlimited number of registrations on Form S-3 (such requests shall
be in writing and shall state the number of shares of Registrable Stock to be
disposed of and the intended method of disposition) except that the Company (a)
shall not be required to effect more than one registration pursuant to this
Section 2.8 in any six-month period, and (b) shall not be required to effect a
registration pursuant to this Section 2.8 unless the Holder or Holders
requesting registration hold an aggregate of at least thirty percent (30%) of
the Registrable Stock then outstanding and propose to dispose of shares of
Registrable Stock having an aggregate expected public offering price (before
deduction of underwriting discounts and expenses of sale) of at least $500,000.

               The Company shall give notice to all Holders of the receipt of a
request for registration pursuant to this Section 2.8 and shall provide a
reasonable opportunity for other Holders to participate in the registration,
provided that if the registration is for an underwritten offering, the terms of
Section 2.4(d) shall apply to all participants in such offering.  Subject to the
foregoing, the Company will use its best efforts to effect promptly the
registration of all shares of Registrable Stock on Form S-3 to the extent
requested by the Holder or Holders thereof.

          2.9  Cooperation by Prospective Sellers.
               ---------------------------------- 

               (a) Each prospective seller of Registrable Stock, and each
underwriter designated by each such seller, will furnish to the Company such
information as the Company may reasonably require from such seller or
underwriter in connection with the registration statement (and the prospectus
included therein).

               (b) Failure of a prospective seller of Registrable Stock to
furnish the information and agreements described in this Section 2 shall not
affect the obligations of the Company under this Section 2 to the remaining
sellers who furnish such information and agreements unless, in the reasonable
opinion of counsel to the Company or the underwriters, such failure impairs or
may impair the viability of the offering or the legality of the registration
statement or the underlying offering.

               (c) The Holders holding shares included in the registration
statement will not (until further notice) effect sales thereof after receipt
of telegraphic or written notice from the Company to suspend sales to permit
the Company to correct or update a registration statement or prospectus but
the obligations of the Company with respect to maintaining any registration
statement current and effective shall be extended by a period of days equal to
the period such suspension is in effect unless (i) such extension would result
in the Company's inability to use the financial statements in the registration
statement initially filed pursuant to the Holder or Holders' request and (ii)
such correction or update did not result from the Company's acts or failures
to act.

                                      -7-

 
               At the end of the period during which the Company is obligated
to keep the registration statement current and effective as described in
Section 2.3(b) (and any extensions thereof required by the preceding
sentence), the Holders holding shares included in the registration statement
shall discontinue sales of shares pursuant to such registration statement upon
receipt of notice from the Company of its intention to remove from
registration the shares covered by such registration statement which remain
unsold, and such Holders shall notify the Company of the number of shares
registered which remain unsold immediately upon receipt of such notice from
the Company.

          2.10 Expenses of Registration.  All expenses incurred in effecting
               ------------------------                                        
any registration pursuant to this Section 2 including, without limitation, all
registration and filing fees, printing expenses, expenses of compliance with
blue sky laws, fees and disbursements of counsel for the Company and expenses of
any audits incidental to or required by any such registration, shall be borne by
the Company, except that (a) all expenses, fees and disbursements of any counsel
retained by the Holders and all underwriting discounts and commissions shall be
borne by the Holders holding the securities registered pursuant to such
registration, according to the quantity of the securities so registered; (b) the
Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to Section 2.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (in which case all participating Holders
shall bear such expenses), unless the Holders of a majority of the Registrable
Securities agree to forfeit their right to one demand registration pursuant to
Section 2.2, provided however, that if immediately prior to the time of such
withdrawal, the Holders have learned of a materially adverse change in the
condition, business or prospects of the Company from that known to the Holders
at the time of their request, then the Holders shall not be required to pay any
of such expenses and shall retain their rights pursuant to Section 2.2; and (c)
the Company shall not be required to pay any expenses associated with any
registration of Registrable Stock requested by Holders pursuant to Section 2.8.

          2.11 Indemnification.
               --------------- 

               (a) To the extent permitted by law, the Company will indemnify
each Holder requesting or joining in a registration, each agent, officer and
director of such Holders, each person controlling such Holder and each
underwriter and selling broker of the securities so registered (collectively,
"Indemnitees") 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 prospectus,
offering circular or other document incident to any registration,
qualification or compliance (or in any related registration statement,
notification or the like) 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 in the light of the circumstances in which
they were made, or any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration, qualification or compliance, and will reimburse each such
Indemnitee, promptly and on a current basis from time to time, for any legal
and any other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action, provided, however, 
                                                             --------  ------- 
that the Company will not be liable in any such case to the extent that any
such claim, loss, 

                                      -8-

 
damage or liability is caused by any untrue statement or omission so made in
strict conformity with written information furnished to the Company by an
instrument duly executed by such Indemnitees and stated to be specifically for
use therein and except that the foregoing indemnity agreement is subject to
the condition that, insofar as it relates to any such untrue statement (or
alleged untrue statement) or omission (or alleged omission) made in the
preliminary prospectus but eliminated or remedied in the amended prospectus on
file with the Commission at the time the registration statement becomes
effective or in the amended prospectus filed with the Commission pursuant to
Rule 424(b) (the "Final Prospectus"), such indemnity agreement shall not inure
to the benefit of any underwriter, or any Indemnitee if there is no
underwriter, if a copy of the Final Prospectus was not furnished to the person
or entity asserting the loss, liability, claim or damage at or prior to the
time such furnishing is required by the Securities Act; provided, further,
that this indemnity shall not be deemed to relieve any underwriter of any of
its due diligence obligations; provided, further, that the indemnity agreement
contained in this Section 2.11(a) shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability or action if such
settlement is effected without the consent of the Company, which consent shall
not be unreasonably withheld.

               (b) To the extent permitted by law, each Holder requesting or
joining in a registration and each underwriter of the securities so registered
will indemnify the Company and its officers and directors and each other
Holder and each person, if any, who controls any thereof within the meaning of
Section 15 of the Securities Act and their respective successors 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 prospectus, offering circular or other document
incident to any registration, qualification or compliance (or in any related
registration statement, notification or the like) 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 in the light of the
circumstances in which they were made and will reimburse, promptly and on a
current basis from time to time, the Company and each other person indemnified
pursuant to this Section 2.11(b) for any legal and any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, provided, however, that this Section 
                                          --------  -------              
2.11(b) shall apply only if (and only to the extent that) such statement or
omission was made in reliance upon and in strict conformity with written
information (including, without limitation, written negative responses to
inquiries) furnished to the Company by an instrument duly executed by such
Holder or underwriter and stated to be specifically for use in such
prospectus, offering circular or other document (or related registration
statement, notification or the like) or any amendment or supplement thereto
and except that the foregoing indemnity agreement is subject to the condition
that, insofar as it relates to any such untrue statement (or alleged untrue
statement) or omission (or alleged omission) made in the preliminary
prospectus but eliminated or remedied in the amended Prospectus on file with
the Commission at the time the registration statement becomes effective or in
the Final Prospectus, such indemnity agreement by a Holder other than an
underwriter shall not inure to the benefit of (i) the Company and (ii) any
underwriter or any Holder, if there is no underwriter, if a copy of the Final
Prospectus was not furnished to the person or entity asserting the loss,
liability, claim or damage at or prior to the time such furnishing is required
by the Securities Act; provided, further, that this indemnity shall not be
                       --------  -------                                  
deemed to relieve any underwriter of any of its due diligence obligations;
                                                                          
provided, further, that the indemnity agreement 
- --------  -------                                                        

                                      -9-

 
contained in this Section 2.11(b) shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability or action if such
settlement is effected without the consent of the Holder or underwriter, as the 
case may be, which consent shall not be unreasonably withheld, and provided, 
                                                                   --------
further, that the obligations of such Holders shall be limited to an amount
- -------
equal to the proceeds to each such Holder from the sale of Registrable Stock
as contemplated herein, unless such claim, loss, damage, liability or action
resulted from such Holder's fraudulent misconduct.

               (c) Each party entitled to indemnification hereunder (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 (at its expense) to assume the defense
of any 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 satisfactory to the Indemnified Party, and the Indemnified 
Party may participate in such defense at such party's expense, and 
provided, further, that the omission by any Indemnified Party to give notice as 
- --------  -------          
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 2.11 except to the extent that the omission results in a
failure of actual notice to the Indemnifying Party and such Indemnifying Party
is damaged solely as a result of the failure to give notice. 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) The reimbursement required by this Section 2.11 shall be
made by periodic payments during the course of the investigation or defense,
as and when bills are received or expenses incurred.

               (e) The obligations under this Section 2.11 shall survive the
redemption and conversion, if any, of the Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock, the completion of any offering of
Registrable Stock in a registration statement under this Section 2, or
otherwise.

          2.12 Rights Which May Be Granted to Subsequent Investors.
               --------------------------------------------------- 

               (a) Within the limitations prescribed by this Section 2.12(a),
but not otherwise, the Company may grant to subsequent investors in the
Company rights of incidental registration (such as those provided in Section
2.5). Such rights may only pertain to shares of Common Stock, including shares
of Common Stock into which any other securities may be converted. Such rights
may be granted with respect to (i) registrations actually requested by
Initiating Holders pursuant to Section 2.2, but only in respect of that
portion of any such registration as remains after inclusion of all Registrable
Stock requested by Holders and (ii) registrations initiated by the Company,
but only in respect of that portion of such registration as is available under
the limitations set forth in Section 2.6 (which limitations shall apply to all
Holders) and such rights shall be limited in all cases to sharing in the
available portion of the registration in question with Holders, such sharing
to be based on the number of shares of Common Stock held by the respective
Holders and held by such other investors, plus the number of shares of Common

                                      -10-

 
Stock into which other securities held by the Holders and such other investors
are convertible, which are entitled to registration rights. With respect to
registrations which are for underwritten public offerings, "available portion"
shall mean the portion of the underwritten shares which is available as
specified in clauses (i) and (ii) of the third sentence of this Section
2.12(a). Shares not included in such underwriting shall not be registered.

               (b) The Company may not grant to subsequent investors in the
Company rights of registration upon request (such as those provided in Section
2.2) unless (i) such rights are limited to shares of Common Stock, (ii) all
Holders are given enforceable contractual rights to participate in
registrations requested by such subsequent investors (the right of priority of
registration being pro rata as between subsequent investors and Holders),
where such participation is on a pro rata basis between subsequent investors
and Holders, (iii) subject to the limitations described in the final three
sentences of Section 2.12(a), such rights shall not become effective prior to
90 days after the effective date of the first registration by the Company
pursuant to Section 2.2 and (iv) such rights shall not be more favorable than
those granted to the Holders.

          2.13 Transfer of Registration Rights.  The registration rights
               -------------------------------                             
granted to each Investor under this Section 2 may be transferred only:

               (a) to a transferee who shall acquire not less than 50,000
shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Registrable Stock (as adjusted for Recapitalization
Events); or

               (b) in connection with the distribution by an Investor of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
or Registrable Stock to the beneficial owners (including, without limitation,
to partners of a general or limited partnership, shareholders of a corporation
and beneficiaries of a trust) of securities of the Investor; or

               (c) in the case of the Phoenix Warrant and the Series B Stock
and Registrable Stock acquirable thereby, to an affiliate of Phoenix.

                   The registration rights may only be transferred if the
Company is, within a reasonable time after such transfer, furnished with
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 only if immediately following such transfer the further disposition of the
applicable securities by the transferee or assignee is restricted under the
Securities Act. Notwithstanding any provision of this Section 2.13, the
registration rights granted to each Investor under this Section 2 may not be
assigned to any person or entity which, in the Company's reasonable judgment,
is a competitor of the Company.

          2.14 "Stand-off" Agreement.  In consideration for the Company
               ---------------------                                      
performing its obligations under this Section 2 each Investor agrees for a
period of time (not to exceed 180 days)  from the effective date of any
registration of securities of the Company (upon request of the Company or of the
underwriters managing any underwritten offering of the Company's securities) not
to sell, make any short sale of, loan, grant any option for the purchase of, or

                                      -11-

 
otherwise dispose of any Registrable Stock, other than shares of Registrable
Stock included in the registration, without the prior written consent of the
Company or such underwriters, as the case may be, provided, however, that all
                                                  --------  -------          
officers and directors of the Company and each holder of more than 5% of the
outstanding Common Stock shall have entered into similar agreements.

     3.   Miscellaneous.
          ------------- 

          3.1  Notices.  All notices, requests, consents and other

3.1) shall be in writing and shall be mailed by first-class or certified mail,

               (b)  If to the Investors:

                    at their respective addresses set forth
                    on Schedule A hereto
                       ----------

          3.2  Modification; Waiver.  Neither this Agreement nor any
               --------------------                                    
provision hereof may be changed, waived, discharged or terminated orally or in
writing, except that any provision of this Agreement may be amended and the
observance of any such provision may be waived (either generally or in a
particular instance and either retroactively or prospectively) with (but only
with) the written consent of (a) the Company, and (b) the Holders of at least
66-2/3% of the 

                                      -12-

 
Registrable Stock (assuming the exercise and/or conversion of all exercisable
or convertible securities). Any amendment or waiver effected in accordance
with this paragraph shall be binding upon each Holder of Registrable
Securities, and the Company. In the event that an underwriting agreement is
entered into between the Company and any Holder, and such underwriting
agreement contains terms differing from this Agreement, as to any such Holder
the terms of such underwriting agreement shall govern.

          3.3  Entire Agreement.  This Agreement contains the entire
               ----------------                                        
agreement between the parties with respect to the transactions contemplated
hereby, and supersedes all negotiations, agreements, representations,
warranties, commitments, whether in writing or oral, prior to the date hereof.

          3.4  Successors and Assigns.  Subject to Section 2.13, all of the
               ----------------------                                         
terms of this Agreement shall be binding upon and inure to the benefit of and be
enforceable by the respective successors and assigns of the parties hereto.

          3.5  Enforcement.
               ----------- 

               (a) Remedies at Law or in Equity.  If the Company shall default 
                   ----------------------------                         
in any of its obligations under this Agreement or if any representation or
warranty made by or on behalf of the Company in this Agreement or in any
certificate, report or other instrument delivered under or pursuant to any
term hereof shall be untrue or misleading in any material respect as of the
date of this Agreement or as of the date it was made, furnished or delivered,
each Investor may proceed to protect and enforce its rights by suit in equity
or action at law, whether for the specific performance of any term contained
in this Agreement, the Company's Articles or for an injunction against the
breach of any such term or in furtherance of the exercise of any power granted
in this Agreement or the Company's Articles, or to enforce any other legal or
equitable right of such Investor or to take any one or more of such actions.
In the event any Investor brings such an action against the Company, the
prevailing party in such dispute shall be entitled to recover from the losing
party all fees, costs and expenses of enforcing any right of such prevailing
party under or with respect to this Agreement or the Company's Articles,
including without limitation such reasonable fees and expenses of attorneys
and accountants, which shall include, without limitation, all reasonable fees,
costs and expenses of appeals.

               (b) Remedies Cumulative; Waiver.  No remedy referred to herein is
                   ---------------------------                                  
intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to above or otherwise available to each Investor at law or
in equity.  No express or implied waiver by any Investor of any default shall be
a waiver of any future or subsequent default.  The failure or delay of each
Investor in exercising any rights granted it hereunder shall not constitute a
waiver of any such right and any single or partial exercise of any particular
right by any Investor shall not exhaust the same or constitute a waiver of any
other right provided herein.

                                      -13-

 
          3.6  Execution and Counterparts.  This Agreement may be executed in
               --------------------------                                       
any number of counterparts, each of which when so executed and delivered shall
be deemed an original, and such counterparts together shall constitute one
instrument.  Each party shall receive a duplicate original of the counterpart
copy or copies executed by it and by the Company.

          3.7  Governing Law and Severability.  This Agreement shall be
               ------------------------------                             
governed by the laws of the State of California as applied to agreements entered
into and to be performed entirely within California.  In the event any provision
of this Agreement or the application of any such provision to any part shall be
held by a court of competent jurisdiction to be contrary to law, the remaining
provisions of this Agreement shall remain in full force and effect.

          3.8  Headings.  The descriptive headings of the Sections hereof are
               --------                                                         
inserted for convenience only and do not constitute a part of this Agreement.

                                      -14-

 
          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.
