                    1.4   REGISTRATION PROCEDURES.  With respect to a 
                          ----------------------- 
     registration effected by the Company pursuant to Section 1.2 hereof, the
     Company shall use its best efforts to:

                           (a)  Keep such registration effective for the
     Registration Period;

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

                           (c)  Furnish such number of prospectuses and other
     documents incident thereto, including any amendment of or supplement to the
     prospectus, as a Holder from time to time may reasonably request.

                           (d)  Notify each seller of Registrable Securities
     covered by such registration statement at any time when a prospectus
     relating thereto is required to be delivered under the Securities Act of
     the happening of any event as a result of which the prospectus included in
     such registration statement, as then in effect, include 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 not misleading or
     incomplete in the light of the circumstances then existing, and at the
     request of any such seller, prepare and furnish to such seller a reasonable
     number of copies of a supplement to or an amendment of such prospectus as
     may be necessary so that, as thereafter delivered to the purchasers 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 not misleading or incomplete in
     the light of the circumstances then existing;

                           (e)  Cause all such Registrable Securities registered
     pursuant hereunder to be listed on each securities exchange on which
     similar securities issued by the Company are then listed;

                                       3

 
                           (f)  Register or qualify all Registrable Securities
     covered by such registration statement under such other United States state
     securities or blue sky laws of such jurisdictions as each Holder shall
     reasonably request, to keep such registration statement qualification in
     effect for the period referred to in Section 1.2 hereof, and take any other
     action which may be reasonably necessary or advisable to enable each Holder
     to consummate the disposition in such jurisdictions of the securities owned
     by each Holder, except that the Company shall not for any such purpose be
     required to (i) qualify generally to do business as a foreign corporation
     in any jurisdiction wherein it would not, but for the requirements of this
     Section 1.4(f), be obligated to be so qualified, (ii) subject itself to
     taxation in any such jurisdiction or (iii) consent to general service of
     process in any such jurisdiction; and

                           (g)  Otherwise comply with all applicable rules and
     regulations of the Commission and not file any amendment or supplement to
     such registration statement or prospectus to which a majority of the Holder
     shall have reasonably objected in writing on the grounds that such
     amendment or supplement does not comply in all material respects with the
     requirements of the Securities Act or of the rules or regulations
     thereunder, having been furnished with a copy thereof (other than with
     respect to pricing amendment or a prospectus filed pursuant to Rule
     424(b)(1) under the Securities Act) at least two business days prior to the
     filing thereof.

                    1.5   INDEMNIFICATION.
                          --------------- 

                           (a)  The Company will indemnify each Holder, each of
     its officers, directors and partners, legal counsel, and accountants and
     each person controlling such Holder within the meaning of Section 15 of the
     Securities Act, against all expenses, claims, losses, damages and
     liabilities (or actions, proceedings or settlements 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 (including any related registration statement,
     notification, or the like) 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 not misleading, or any violation
     by the Company of the Securities Act or any rule or regulation thereunder
     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 Holder, each of its officers,
     directors, partners, legal counsel, and accountants and each person
     controlling such Holder, for any legal and any other expenses reasonably
     incurred in connection with investigating and defending or settling 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 based upon written information furnished to the
     Company by such Holder and stated to be specifically for use therein. It is
     agreed that the indemnity agreement contained in this Section 1.5(a) shall
     not apply to amounts paid in settlement of any such loss, claim, damage,
     liability, or action if such settlement is effected without the consent of
     the Company (which consent has not been unreasonably withheld).

                                       4

 
                           (b)  Each Holder will, if Registrable Securities 
     held by him are included in the securities as to which such registration,
     qualification, or compliance is being effected, indemnify the Company, each
     of its directors, officers, partners, legal counsel, and accountants, each
     other, such Holder and Other Shareholder, and each of their officers,
     directors and partners, and each person controlling such Holder or Other
     Shareholder, 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 and such Holders, Other
     Shareholders, directors, officers, partners, legal counsel, and
     accountants, 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 furnished to the
     Company by such Holder and stated to be specifically for use therein;
     provided, however, that the obligations of such Holder hereunder shall not
     apply to amounts paid in settlement of any such claims, losses, damages, or
     liabilities (or actions in respect thereof) if such settlement is effected
     without the consent of such Holder (which consent shall not be unreasonably
     withheld).

                           (c)  Each party entitled to indemnification under 
     this Section 1.5 (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 such claim or any litigation resulting therefrom, provided
     that counsel for the Indemnifying Party, who shall conduct the defense of
     such claim or any litigation resulting therefrom, 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, and provided further that the failure of any Indemnified Party to
     give notice as provided herein shall not relieve the Indemnifying Party of
     its obligations under this Section 1, except to the extent that the
     Indemnifying Party is actually prejudiced by such failure to give notice.
     Notwithstanding the foregoing, the Indemnified Party or Parties shall have
     the right to employ its or their own counsel in any such case but the fees
     and expenses of such counsel shall be at the expense of such Indemnified
     Party or Parties unless (i) the employment of such counsel shall have been
     authorized in writing by the Indemnifying Parties in connection with the
     defense of such action at the expense of the Indemnifying Party or Parties,
     (ii) the Indemnifying Party or Parties shall not have employed counsel
     reasonably satisfactory to such Indemnified Party or Parties to have charge
     of the defense of such action within a reasonable time after notice of the
     commencement of the action or (iii) such Indemnified Party or Parties shall
     have reasonably concluded that there may be defenses available to it or
     them which are different from or additional to those available to one or
     all of the Indemnifying Parties (in which case the Indemnifying Parties
     shall not have the right to direct the defense of such action on behalf of
     the Indemnified Party or Parties),  

                                       5

 
     in any of which events such fees and expenses of one additional counsel
     shall be borne by Indemnifying Party or Parties. 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 that 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. Each Indemnified
     Party shall furnish such information regarding itself or the claim in
     question as an Indemnifying Party may reasonably request in writing and as
     shall be reasonably required in connection with defense of such claim and
     litigation resulting therefrom.

                           (d)  If the indemnification provided for in this
     Section 1.5 is unavailable to an Indemnified Party with respect to any
     loss, liability, claim, damage, or expense referred to therein, then the
     Indemnifying Party, in lieu of indemnifying such Indemnified Party
     hereunder, shall contribute to the amount paid or payable by such
     Indemnified Party as a result of such loss, liability, claim, damage, or
     expense 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 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 of the Indemnified Party shall be determined by reference to,
     among other things, whether the action in question, including any untrue or
     alleged, untrue statement of a material fact or 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 actions, statement or omission. The amount paid or payable by
     a party as a result of the losses, claims, damages, liabilities and
     expenses referred to above shall be deemed to include any legal or other
     fees or expenses reasonably incurred by such party in connection with any
     investigation or proceeding. The parties hereto agree that it would not be
     just and equitable if contribution pursuant to this Section 1.5(d) were
     determined by pro rata allocation or by any other method of allocation that
     does not take account of the equitable considerations referred to in this
     paragraph. No person guilty of fraudulent misrepresentation (within the
     meaning of Section 10(f) of the Securities Act) shall be entitled to
     contribution from any person.

                   If indemnification is available under this Section 1.5, the
     Indemnifying Party or Parties shall indemnify each Indemnified Party or
     Parties to the full extent provided herein without regard to the relative
     fault of said Indemnifying Parties or Indemnified Parties or any other
     equitable consideration provided for in this Section 1.5(d).

                    1.6   INFORMATION BY HOLDER.  Each Holder of Registrable
                          ---------------------                             
     Securities shall furnish to the Company such information regarding such
     Holder and the distribution proposed by such Holder 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 Section 1.

                                       6

 
                    1.7   RULE 144 REPORTING.  With a view to making available 
                          ------------------ 
     the benefits of certain rules and regulations of the Commission that may
     permit the sale of the Restricted Securities to the public without
     registration, the Company agrees to use its best efforts to:

                           (a)  Make and keep public information regarding the
     Company available as those terms are understood and defined in Rule 144
     under the Securities Act;

                           (b)  File with the Commission in a timely manner all
     reports and other documents required of the Company under the Securities
     Act and the Exchange Act at any time after it has become subject to such
     reporting requirements;

                           (c)  So long as a Holder owns any Restricted
     Securities, furnish to Holder forthwith upon written request a written
     statement by the Company as to its compliance with the reporting
     requirements of Rule 144, a copy of the most recent annual or quarterly
     report of the Company, and such other reports and documents so filed as a
     Holder may reasonably request in availing itself of any rule or regulation
     of the Commission allowing a Holder to sell any such securities without
     registration.

                    1.8   TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS.  The
                          ---------------------------------------------      
     rights to cause the Company to register securities granted to a Holder by
     the Company under this Section 1 may be transferred or assigned by a
     Holder, provided that the Company is given written notice at the time of or
     within a reasonable time after said transfer or assignment, stating the
     name and address of the transferee or assignee and identifying the
     securities with respect to which such registration rights are being
     transferred or assigned, and, provided further, that the transferee or
     assignee of such rights assumes the obligations of such Holder under this
     Agreement by a written agreement reasonably acceptable to the Company.

                    1.9   "MARKET STAND-OFF" AGREEMENT.  If requested by the
                          ----------------------------                      
     Company and an underwriter of common stock (or other securities) of the
     Company, a Holder shall not sell or otherwise transfer or dispose of any
     Registrable Securities held by such Holder during such period, not
     exceeding 90 days, following the effective date of the registration
     statement of the Company covering such underwritten offering filed under
     the Securities Act specified by the Company; provided that foregoing
     restriction shall apply only if (a) each director and executive officer of
     the Company agrees to a similar restriction on the sale of his or her
     shares, and (b) there are no shareholders selling shares in the
     underwritten public offering unless the Holders are also offered the
     opportunity to sell their Registrable Securities in the underwritten public
     offering.  The Registration Period shall not include the period during
     which foregoing stand-off obligations are in effect.

                   The obligations described in this Section 1.9 shall not apply
     to a registration relating solely to employee benefit plans on Form S-1 or
     Form S-8 or similar forms that may be promulgated in the future, or a
     registration relating solely to a Commission Rule 145 transaction on Form 
     S-4 or similar forms that may be promulgated in the future.

                                       7

 
                    1.10  DELAY OF REGISTRATION.  No Holder shall have any right
                          ---------------------                                 
     to take any action to restrain, enjoin, or otherwise delay any registration
     as the result of any controversy that might arise with respect to the
     interpretation or implementation of this Agreement.

              2.   MISCELLANEOUS

                    2.1   GOVERNING LAW.  This Agreement shall be governed in 
                          ------------- 
     all respects by the laws of the state of California, as if entered into by
     and between California residents exclusively for performance entirely
     within California.
