          2.  Registration under Securities Act etc.
              --------------------------------------

              2.1  Registration on Request.
                   -----------------------

               (a) Demand Request.  Upon the written request of the Initiating
                   --------------
Holders (on their own and/or on behalf of the other Stockholders), requesting
that the Company effect the registration under the Securities Act of all or part
of such initiating Holders' Registrable Securities or the Registrable Securities
owned by other Stockholders and specifying the intended method or methods of
disposition thereof (a "Demand Request"), the Company will, as promptly as
reasonably practicable but in no event later than 20 days after such request,
give written notice of such requested registration to all registered holders of
Registrable Securities who would be entitled to participate in such
registration, and thereupon the Company will, subject to the terms of this
Agreement, use its best efforts to effect the registration under the Securities
Act of:

                                       1


               (i)    the Registrable Securities which the Company has been so
     requested to register by such Initiating Holders (on their own and/or on
     behalf of the other Stockholders) for disposition in accordance with the
     intended method or methods of disposition stated in such request;

               (ii)   all other Registrable Securities the holders of which
     shall have made a written request to the Company for registration thereof
     within 30 days after the receipt of such written notice from the Company
     (which request shall specify the intended method or methods of disposition
     of such Registrable Securities);

               (iii)  all shares of Common Stock which the Company may elect to
     register in connection with the offering of Registrable Securities pursuant
     to this section 2.1; and

               (iv)   all shares of Common Stock which the Company may be
     required to register in connection with "piggyback" or incidental
     registration rights granted to any other Person;

all to the extent requisite to permit the disposition (in accordance with the
intended method or methods of distribution specified in the Demand Request) of
the Registrable Securities and the additional shares of Common Stock, if any, so
to be registered, provided, however that such Demand Request shall be for not
                  --------  -------
less than 400,000 shares of Common Stock. Subject to the provisions of section
2. 1(d), the Initiating Holders will have the right pursuant to this section 2.
1(a) to make one Demand Request.

          Without limiting the generality of the foregoing, the Initiating
Holders shall have the right to request registration pursuant to this Section
2.1 and specify that one of the methods of disposition of Registrable Securities
shall be a block trade or trades involving Registrable Securities held by such
Initiating Holders and/or other Stockholders and that, in connection therewith,
the Company shall file with the Commission a registration statement under Rule
415 covering all of the Registrable Securities to be sold in the block trade or
trades.  In such case, the Company shall file an appropriate shelf registration
statement with the Commission as promptly as reasonably practicable and in
accordance with the provisions of section 2.3.  Subject to the provisions of
section 2.1(d), a shelf registration which involves a block trade or block
trades as an intended method of disposition, whether or not any such block

                                       2


trade is made, shall be considered as the exercise of the Demand Request
permitted by this section 2.1(a).

          Notwithstanding anything herein to the contrary, it is understood and
agreed that the Initiating Holders may make a Demand Request for registration
pursuant to this section 2.1(a) 30 days prior to the date on which it is agreed
by the parties that the restricted period under Accounting Series Release No.
135 would expire.

          (b) Registration Statement Form.  The registration under this section
              ---------------------------
2. l shall be on such appropriate registration form of the Commission (i) as
shall be selected by the Company and, as shall be reasonably acceptable to the
Initiating Holders of the Registrable Securities so to be registered and (ii) as
shall permit the disposition of such Registrable Securities in accordance with
the intended method or methods of disposition specified in the request for such
registration.

          (c) Expenses. The Company will pay all Registration Expenses in
              --------
connection with the registration requested pursuant to this section 2.l
(including any registration deemed not to be "effected" under section 2.l).

          (d) Effective Registration Statement.  The registration requested
              --------------------------------
pursuant to this section 2.l shall not be deemed to have been effected (and
therefore shall not constitute the Demand Request) (i) unless the registration
statement with respect thereto has become effective in accordance with the
manner of disposition specified by the requesting holders, provided that a
                                                           --------
registration which does not become effective after the Company has filed the
registration statement with respect thereto solely by reason of the refusal to
proceed of the Initiating Holders (other than a refusal to proceed based upon
the advice of counsel relating to a matter with respect to the Company) shall be
deemed to have been effected by the Company at the request of the Initiating
Holders unless the Initiating Holders shall have elected to pay all Registration
Expenses in connection with such registration, (ii) if, after it has become
effective, such registration becomes subject to any stop order, injunction or
other order or requirement of the Commission or other governmental agency or
court for any reason, or (iii) if the conditions to closing specified in the
purchase agreement or underwriting agreement, if any, entered into in connection
with such registration are not satisfied, other than by reason of some act or
omission by a holder of Registrable Securities.

                                       3


          (e) Selection of Underwriters.  If a requested registration pursuant
              -------------------------
to this section 2.1 involves an underwritten offering, the underwriter or
underwriters thereof shall be selected by the Company, subject to the approval
of the holders of a majority of the Registrable Securities which the Company has
been requested to register, which approval shall not be unreasonably withheld.

          (f) Priority in Requested Registrations. If the requested registration
              -----------------------------------
pursuant to this section 2.l involves an underwritten offering, and the managing
underwriter shall advise the Company in writing (with a copy to each holder of
Registrable Securities requesting registration) that, in its opinion, the number
of securities requested to be included in such registration (including
securities of the Company which are not Registrable Securities) exceeds the
number which can be sold in such offering within a price range acceptable to the
holders of a majority of the Registrable Securities requested to be included in
such registration, the Company will include in such registration, to the extent
of the number which the Company is so advised can be sold in such offering, (i)
first, Registrable Securities requested to be included in such registration by
the holders of Registrable Securities, pro rata among such holders requesting
                                       --- ----
such registration on the basis of the number of such securities requested to be
included by such holders, and (ii) second, subject to section 2.1(a) hereof,
securities the Company proposes to sell and other securities of the Company
included in such registration by other holders who may have "piggyback" or
incidental registration rights.

          (g) Delay Periods.  The Company shall be entitled to Postpone the
              -------------
filing of any registration statement otherwise required to be prepared and filed
by the Company pursuant to this section 2.1, or suspend the use of any effective
registration statement under this section 2.1, for a reasonable period of time,
but not in excess of 90 days (a "Delay Period"), if (i) such postponement or
suspension is required by applicable law arising from events outside of the
control of the Company or (ii) any senior executive officer of the Company
determines that in such senior executive officer's reasonable good faith
judgment the registration and distribution of the Registrable Securities covered
or to be covered by such registration statement would interfere with any pending
material financing, acquisition, corporate reorganization, business combination,
joint venture, strategic alliance, commercial alliance, customer contract or
other transaction involving the Company or any of its subsidiaries or would
require premature disclosure thereof and promptly gives the initiating Holders
written notice of such determination, and an approximation of the period of the
anticipated delay; provided, however, that (i) the aggregate number of days
included in all Delay Periods during any consecutive 12 months shall not exceed
the

                                       4


aggregate of 180 days and (ii) a period of at least 90 days shall elapse
between the termination of any Delay Period and the commencement of the
immediately succeeding Delay Period.  Immediately upon receipt of a written
notice of suspension, each holder of Registrable Securities who made a request
to participate in the underwritten offering pursuant to this section 2.1 shall
cease all disposition efforts with respect to Registrable Securities held by
such holder.  If the Company shall so postpone the filing of a registration
statement, the Holders of Registrable Shares to be registered shall
automatically be deemed to have withdrawn the request for registration and such
request shall not constitute the Demand Request for registration to which the
Initiating Holders of Registrable Shares are entitled pursuant to this section
2.l.  The time period for which the Company is required to maintain the
effectiveness of the registration statement shall be extended by the aggregate
Delay Periods during such registration.

              2.2  Incidental Registration.
                   -----------------------

              (a)  Right to Include Registrable Securities.  If the Company at
                   ---------------------------------------
any time proposes to register any of its shares of Common Stock (other than in
connection with a registration of securities which are convertible or
exchangeable into Common Stock) under the Securities Act (other than by a
registration on Form S-4 or S-8, or any successor or similar forms and other
than pursuant to section 2.1), whether or not for sale for its own account, it
will each such time give prompt written notice to all holders of Registrable
Securities of its intention to do so and of such holders' rights under this
section 2.2.  Upon the written request of any such holder made within 30 days
after the receipt of any such notice (which request shall specify the
Registrable Securities intended to be disposed of by such holder and the
intended method or methods of disposition thereof), the Company will, subject to
the terms of this Agreement, use its best efforts to effect the registration
under the Securities Act of all Registrable Securities which the Company has
been so requested to register by the holders thereof, to the extent requisite to
permit the disposition (in accordance with the intended method or methods of
distribution thereof specified in the requests of such holders) of the
Registrable Securities so to be registered, by inclusion of such Registrable
Securities in the registration statement which covers the securities which the
Company proposes to register; provided that if, at any time after giving written
                              --------
notice of its intention to register any securities and prior to the effective
date of the registration statement flied in connection with the registration of
the Registrable Securities and the securities which the Company proposes to
sell, the Company shall determine for any reason either not to register or to
delay registration of the securities which the Company proposes to sell, the
Company may, at its election, postpone or

                                       5


withdraw the registration statement and give written notice of such
determination to each holder of Registrable Securities and, thereupon, (i) in
the case of a determination not to register, shall be relieved of its obligation
to register any Registrable Securities in connection with such registration (but
not from its obligation to pay the Registration Expenses in connection
therewith), without prejudice, however, to the rights of any holder or holders
of Registrable Securities entitled to do so to request that such registration be
effected as a registration under section 2.l, and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities, for the same period as the delay in registering such
other securities. No registration effected under this section 2.2 shall relieve
the Company of its obligation to effect any registration upon request under
section 2.l, nor shall any such registration hereunder be deemed to have been
effected pursuant to section 2.1. The Company will pay all Registration Expenses
in connection with each registration of Registrable Securities requested
pursuant to this section 2.2, and each holder whose Registrable Securities are
included in a registration requested pursuant to this section 2.2 will pay any
underwriting discounts and commissions and fees of such holder's counsel in
connection therewith.

          (b) Priority in Incidental Registrations.  If (i) a registration
              ------------------------------------
pursuant to this section 2.2 involves an underwritten offering of the securities
so being registered, whether or not for sale for the account of the Company, to
be distributed (on a firm commitment basis) by or through one or more
underwriters of recognized standing under underwriting terms appropriate for
such a transaction, and (ii) the managing underwriter of such underwritten
offering shall inform the Company and holders of the Registrable Securities
requesting such registration by letter of its belief that the number of
securities requested to be included in such registration exceeds the number
which can be sold in (or during the time of) such offering, then the Company
will include in such registration:

               (i)   first, all the securities the Company proposes to sell for
     its own account,

               (ii)  second, all securities of any other holder who has made a
     demand for registration, and

               (iii) third, to the extent that the number of securities which
     the Company and any such other holders proposed to include pursuant to
     clauses (i) and (ii) is less than the number of securities which the
     Company has been advised can be sold in such

                                       6


     offering, the number of (x) such Registrable Securities requested to be
     included in such registration by the holders of Registrable Securities
     pursuant to section 2.2(a) hereof and (y) other equity securities of the
     Company requested to be included in such registration by holders of such
     securities who are entitled to incidental registration rights under any
     other registration rights agreements with the Company shall be allocated
     pro rata among all such holders on the basis of the relative number of
     --- ----
     Registrable Securities and other equity securities each such holder has
     requested to be included in such registration.

          2.3    Registration Procedures.  If and whenever the Company is
                 -----------------------
required to effect the registration of any Registrable Securities under the
Securities Act as provided in sections 2.l and 2.2, the Company shall, as
expeditiously as reasonably possible:

               (i)  prepare and file with the Commission the requisite
     registration statement to effect such registration (including such audited
     financial statements as may be required by the Securities Act or the rules
     and regulations promulgated thereunder) and thereafter cause such
     registration statement to become and remain effective for a period of at
     least 120 days, provided however that the Company may discontinue any
                     --------
     registration of its securities which are not Registrable Securities (and,
     under the circumstances specified in section 2.2(a), its securities which
     are Registrable Securities) at any time prior to the effective date of the
     registration statement relating thereto;

               (ii) 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 for a period of at least 120 days (30 days in the case
     of any registration pursuant to section 2.2) and to comply with the
     provisions of the Securities Act with respect to the disposition of all
     securities covered by such registration statement until the earlier of such
     time as all of such securities have been disposed of in accordance with the
     intended methods of disposition by the seller or sellers thereof set forth
     in such registration statement or such other time as is required by the
     Securities Act;

                                       7


               (iii) furnish to each seller of Registrable Securities covered by
     such registration statement and each underwriter, if any, of the securities
     being sold by such seller such number of conformed copies of such
     registration statement and of each such amendment and supplement thereto
     (in each case including all exhibits), such number of copies of the
     prospectus contained in such registration statement (including each
     preliminary prospectus and any summary prospectus) and any other prospectus
     filed pursuant to Rule 424 under the Securities Act, in conformity with the
     requirements of the Securities Act, and such other documents, as such
     seller and underwriter, if any, may reasonably request;

               (iv)  use its best efforts to register or qualify all Registrable
     Securities and other securities covered by such registration statement
     under such other state securities laws or blue sky laws of such
     jurisdictions as any seller thereof and any underwriter of the securities
     being sold by such seller shall reasonably request, to keep such
     registrations or qualifications in effect for so long as such registration
     statement remains in effect, and take any other action which may be
     reasonably necessary or advisable to enable such seller and underwriter to
     consummate the disposition in such jurisdictions of the securities owned by
     such seller, except that the Company shall not for any such purpose be
     required to qualify generally to do business as a foreign corporation in
     any jurisdiction wherein it would not but for the requirements of this
     subsection (iv) be obligated to be so qualified or to consent to general
     service of process in any such jurisdiction;

               (v)   furnish to each seller of Registrable Securities a signed
     counterpart, addressed to such seller and the underwriters, if any, of:

                    (X) an opinion of counsel for the Company (which shall be
          outside counsel if outside counsel is rendering such opinion in the
          transaction and otherwise may be the Company's inside counsel), dated
          the effective date of such registration statement (or, if such
          registration includes an underwritten public offering, an opinion
          dated the date of the closing under the underwriting agreement),
          customary for a transaction of such type, and

                                       8


                    (Y) a "comfort" letter (or, in the case of any such Person
          which does not satisfy the conditions for receipt of a "comfort"
          letter specified in Statement on Auditing Standards No. 72, as amended
          by Statements on Auditing Standards Nos. 76 and 86, an "agreed upon
          procedures" letter), dated the effective date of such registration
          statement (and, if such registration includes an underwritten public
          offering, a letter of like kind dated the date of the closing under
          the underwriting agreement), signed by the independent public
          accountants who have certified the Company's financial statements
          included in such registration statement, covering substantially the
          same matters with respect to such registration statement (and the
          prospectus included therein) and, in the case of the accountants'
          letter, with respect to events subsequent to the date of such
          financial statements, as are customarily covered in opinions of
          issuer's counsel and in accountants' letters delivered to the
          underwriters in underwritten public offerings of securities (with, in
          the case of an "agreed upon procedures" letter, such modifications or
          deletions as may be required under Statement on Auditing Standards No.
          75) and, in the case of the accountants' letter, such other financial
          matters customarily covered in a transaction of such type;

               (vi)  notify the holders of Registrable Securities and the
     managing underwriter or underwriters, if any, promptly:

                    (V) when the registration statement, the prospectus or any
          prospectus supplement related thereto or post-effective amendment to
          the registration statement has been filed, and, with respect to the
          registration statement or any post-effective amendment thereto, when
          the same has become effective;

                    (W) of any request by the Commission for amendments or
          supplements to the registration statement or the prospectus or for
          additional information;

                    (X) of the issuance by the Commission of any stop order
          suspending the effectiveness of the registration statement or the
          initiation of any proceedings by any Person for that purpose;

                                       9


                    (Y) if at any time the representations and warranties of the
          Company made as contemplated by section 2.4 below cease to be true and
          correct; and

                    (Z) of the receipt by the Company of any notification with
          respect to the suspension of the qualification of any Registrable
          Securities for sale under the securities or blue sky laws of any
          jurisdiction or the initiation or threat of any proceeding for such
          purpose;

               (vii)  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, upon the Company's
     discovery that, or upon the happening of any event as a result of which,
     the prospectus included in such registration statement, as then in effect,
     includes an untrue statement of a material fact or omits to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading in the light of the circumstances under
     which they were made, and at the request of any such seller promptly
     prepare and furnish to such seller and each underwriter, if any, 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 securities, 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 in the light of the circumstances under which they were made;

               (viii) make every reasonable effort to obtain the withdrawal of
     any order suspending the effectiveness of the registration statement as
     promptly as possible;

               (ix)   otherwise use its best efforts to comply with all
     applicable rules and regulations of the Commission, and, if required, make
     available to its security holders, as soon as reasonably practicable, an
     earnings statement covering the period of at least twelve months, but not
     more than eighteen months, beginning with the first day of the Company's
     first full calendar quarter after the effective date of such registration
     statement, which earnings statement

                                      10


     shall satisfy the provisions of Section 11(a) of the Securities Act and
     Rule 158 thereunder, and use its best efforts to furnish to each such
     seller at least one business day prior to the filing thereof a copy of any
     amendment or supplement to such registration statement or prospectus and
     shall not file any thereof to which any such seller shall have reasonably
     objected 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;

               (x)  provide and cause to be maintained a transfer agent and
     registrar for all Registrable Securities covered by such registration
     statement from and after a date not later than the effective date of such
     registration statement; and

               (xi) use its best efforts to list all Registrable Securities
     covered by such registration statement on any securities exchange on which
     any of the securities of the same class as the Registrable Securities are
     then listed.

          The Company will not file any registration statement or amendment
thereto or any prospectus or any supplement thereto to which the holders of at
least a majority of the Registrable Securities covered by such registration
statement or the underwriter or underwriters, if any, shall reasonably object.

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish the Company such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing in order to assure compliance
with applicable securities laws and applicable rules and regulations of
securities exchanges.

          Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
occurrence of any event of the kind described in paragraph (vii) of this section
2.3, such holder will forthwith discontinue such holder's disposition of
Registrable Securities pursuant to the registration statement relating to such
Registrable Securities until such holder's receipt of the copies of the
supplemented or amended prospectus contemplated by paragraph (vii) of this
section 2.3 and, if so directed by

                                      11


the Company, will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies, then in such holder's possession of the
prospectus relating to such Registrable Securities current at the time of
receipt of such notice. In the event the Company shall give any such notice, the
period mentioned in paragraph (ii) of this section 2.3 shall be extended by the
length of the period from and including the date when each seller of any
Registrable Securities covered by such registration statement shall have
received such notice to the date on which each such seller has received the
copies of the supplemented or amended prospectus contemplated by paragraph (vii)
of this section 2.3.

          2.4  Underwritten Offerings.
               ----------------------

          (a)  Requested Underwritten Offerings.  If requested by the
               --------------------------------
underwriters for any underwritten offering by holders of Registrable Securities
pursuant to a registration requested under section 2.l, the Company will enter
into an underwriting or similar agreement with such underwriters for such
offering, such agreement to be reasonably satisfactory in substance and form to
the Company, each such holder and the underwriters, and to contain such
representations and warranties by the Company and such other terms as are
generally prevailing in agreements of this type, including, without limitation,
indemnities to the effect and to the extent provided in section 2.6.  The
holders of the Registrable Securities will cooperate with the Company in the
negotiation of the underwriting or similar agreement and will give consideration
to the reasonable suggestions of the Company regarding the form thereof,
provided that nothing herein contained shall diminish the foregoing obligations
- --------
of the Company.  The holders of Registrable Securities to be distributed by such
underwriters shall be parties to such underwriting agreement, which agreement
shall provide that any or all of the representations and warranties by, and the
other agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of such holders of
Registrable Securities and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement shall be
conditions precedent to the obligations of such holders of Registrable
Securities.  No underwriting or similar agreement shall require any holder of
Registrable Securities to make any representations or warranties to or
agreements with the Company or the underwriters, other than representations and
warranties or agreements regarding such holder, such holder's Registrable
Securities and such holder's intended method or methods of distribution and any
other representation required by law, or to make any agreements with the Company
or the underwriters with respect to indemnification of any Person or the
contribution obligations of any Person that would impose any obligation

                                      12


which is broader than the indemnity furnished by such holder pursuant to the
provisions of section 2.6. In addition, the holders of Registrable Securities
shall cooperate with the Company in an effort to provide that any such agreement
will contain a provision modifying the indemnification of the underwriter to the
effect that neither the Company nor the holders of the Registrable Securities
will be liable to any Person who participates as an underwriter in the offering
or sale of Registrable Securities with respect to any preliminary prospectus, to
the extent that any such loss, claim, damage or liability of such underwriter
results from such underwriter having sold Registrable Securities to a person to
whom there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the final prospectus, if the Company has previously
furnished copies thereof to such underwriter and such final prospectus as then
amended or supplemented, has corrected any such misstatement or omission.

          (b) Incidental Underwritten Offerings.  If the Company at any time
              ---------------------------------
proposes to register any of its securities under the Securities Act as
contemplated by section 2.2 and such securities are to be distributed by or
through one or more underwriters, the Company will, if requested by any holder
of Registrable Securities as provided in section 2.2 and subject to the
provisions of section 2.2(b), use its best efforts to arrange for such
underwriters to include all the Registrable Securities to be offered and sold by
such holder among the securities to be distributed by such underwriters.  The
holders of Registrable Securities to be distributed by such underwriters shall
be parties to the underwriting agreement between the Company and such
underwriters, which agreement shall provide that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of such holders of Registrable Securities and that any or all of
the conditions precedent to the obligations of such underwriters under such
underwriting agreement be conditions precedent to the obligations of such
holders of Registrable Securities. Any such holder of Registrable Securities
shall not be required to make any representations or warranties to or agreements
with the Company or the underwriters, other than representations, warranties or
agreements regarding such holder, such holder's Registrable Securities and such
holder's intended method or methods of distribution and any other representation
required by law, or to make any agreements with the Company or the underwriters
with respect to indemnification of any Person or the contribution obligations of
any Person that would impose any obligation which is broader than the indemnity
furnished by such holder pursuant to the provisions of section 2.6.  In
addition, the holders of Registrable Securities shall cooperate with the Company
in an effort to provide that any such agreement will

                                      13


contain a provision modifying the indemnification of the underwriter to the
effect that neither the Company nor the holders of the Registrable Securities
will be liable to any Person who participates as an underwriter in the offering
or sale of Registrable Securities with respect to any preliminary prospectus, to
the extent that any such loss, claim, damage or liability of such underwriter
results from such underwriter having sold Registrable Securities to a person to
whom there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the final prospectus, if the Company has previously
furnished copies thereof to such underwriter and such final prospectus as then
amended or supplemented, has corrected any such misstatement or omission.

           (c)  Holdback Agreements.
                -------------------

               (i)  Each holder of Registrable Securities agrees by acquisition
     of such Registrable Securities, if and to the extent so required by the
     managing underwriter, not to sell, make any short sale of, loan, grant any
     option for the purchase of, effect any public sale or distribution of or
     otherwise dispose of any securities of the Company, during the 7 days prior
     to and the 90 days after any underwritten registration pursuant to section
     2.l or 2.2 has become effective and in which the holders of Registrable
     Securities have the opportunity to participate, except as part of such
     underwritten registration, whether or not such holder participates in such
     registration, unless the underwriters managing the registered public
     offering otherwise agree, provided that the foregoing restrictions shall
                               --------
     not apply with regard to any Stockholder to the transfer to any Affiliate
     of such Person, or to any bona fide pledge of such Registrable Securities,
     provided that such Affiliate or other transferee and/or lender or creditor
     acknowledges in writing that it is bound by the provisions of this section
     2.4(c).  Each holder of Registrable Securities agrees that the Company may
     instruct its transfer agent to place stop transfer notations in its records
     to enforce this section 2.4(c).

               (ii) The Company agrees (X) if so required by the managing
     underwriter not to sell, make any short sale of, loan, grant any option for
     the purchase of, effect any sale or distribution of or otherwise dispose of
     its equity securities or securities convertible into or exchangeable or
     exercisable for any of such securities during the seven days prior to and
     the 90 days after any underwritten registration

                                      14


     pursuant to section 2.1 or 2.2 has become effective, except as part of such
     underwritten registration and except pursuant to registrations on Form S-4,
     S-8, or any successor or similar forms thereto, and (Y) to cause each
     holder of its securities purchased from the Company, or any securities
     convertible into or exchangeable or exercisable for such securities, at any
     time after the date of this Agreement (other than in a public offering) to
     agree not to sell, make any short sale of, loan, grant any option for the
     purchase of, effect any sale or distribution of or otherwise dispose of
     such securities during such periods, unless the underwriters managing the
     registered public offering otherwise agree.

          (d) Participation in Underwritten Offerings.  No Person may
              ---------------------------------------
participate in any underwritten offering hereunder unless such Person (i) agrees
to sell such Person's securities on the basis provided in any underwriting
arrangements approved, subject to the terms and conditions hereof, by the
Company and the holders of a majority of the Registrable Securities to be
included in such underwritten offering and the Initiating Holders, if
applicable, and (ii) completes and executes all questionnaires, indemnities,
underwriting agreements and other documents (other than powers of attorney)
required under the terms of such underwriting arrangements.  Notwithstanding the
foregoing, no underwriting agreement (or other agreement in connection with such
offering) shall require any holder of Registrable Securities to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations and warranties regarding such holder,
such holder's Registrable Securities and such holder's intended method or
methods of distribution and any other representation required by law, or to make
any agreements with the Company or the underwriters with respect to
indemnification of any Person or the contribution obligations of any Person that
would impose any obligation which is broader than the indemnity furnished by
such holder pursuant to the provisions of section 2.6.

          2.5    Preparation: Reasonable Investigation.  In connection with the
                 -------------------------------------
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the holders of Registrable
Securities registered under such registration statement, their underwriters, if
any, and their respective counsel and accountants, the opportunity to
participate in the preparation of such registration statement, each prospectus
included therein or filed with the Commission, and each amendment thereof or
supplement thereto, and will give each of them such reasonable access during
normal business hours to its books, records, and properties, and cause the
Company's officers, employees and the

                                      15


independent public accountants who have certified its financial statements to
supply all information reasonably requested by such holders' and such
underwriters' respective counsel, to conduct a reasonable investigation within
the meaning of the Securities Act.

          2.6  Indemnification.
               ---------------

          (a)  Indemnification by the Company.  In the event of any registration
               ------------------------------
of any securities of the Company under the Securities Act pursuant to section
2.l or 2.2, the Company will, and hereby does agree to, indemnify and hold
harmless the holder of any Registrable Securities covered by such registration
statement and its partners, if any, its and their respective directors,
officers, partners, agents and Affiliates, each other Person who participates as
an underwriter in the offering or sale of such securities and each other Person,
if any, who controls such holder or any such underwriter within the meaning of
the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such holder or partner thereof or any such director or officer
or partner or agent or Affiliate or underwriter or controlling person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered under the
Securities Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, 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
the Company will reimburse such holder, its respective partners and each such
director, officer, partner, agent, Affiliate, underwriter and controlling person
for any legal or any other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, liability, action or
proceeding, provided that the Company shall not be liable in any such case to
            --------
the extent that any such loss, claim, damage, liability (or act on or proceeding
in respect thereof) or expense arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity
with written information furnished to the Company through an instrument duly
executed by such holder, specifically stating that it is for use in the
preparation thereof.  Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such holder or partner
thereof or any

                                      16


such director, officer, partner, agent, Affiliate, underwriter or controlling
person and shall survive the transfer of such securities by such holder. The
indemnity agreement contained in this section 2.6 shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, action or
proceeding if such settlement is effected without the consent of the Company,
which consent shall not be unreasonably withheld.

          (b) Indemnification by the Sellers.  The Company may require, as a
              ------------------------------
condition to including any Registrable Securities in any registration statement
filed pursuant to section 2.3, that the Company shall have received an
undertaking reasonably satisfactory to it from the prospective seller of such
Registrable Securities, to indemnify severally, not jointly and severally, and
hold harmless (in the same manner and to the same extent as set forth in
subsection (a) of this section 2.6) the Company, each director of the Company,
each officer of the Company and each other person, if any, who controls the
Company within the meaning of the Securities Act, with respect to any statement
or alleged statement in or omission or alleged omission from such registration
statement, any preliminary prospectus, final prospectus or summary prospectus
contained therein, or any amendment or supplement thereto, if such statement or
alleged statement or omission or alleged omission was made in reliance upon and
in conformity with written information furnished to the Company by the
prospective seller of the Registrable Securities through an instrument duly
executed by such seller specifically stating that it is for use in the
preparation of such registration statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement.  Any such indemnity
shall remain in full force and effect, regardless of any investigation made by
or on behalf of the Company or any such director, officer or controlling person
and shall survive the transfer of such securities by such seller.  The indemnity
agreement provided for in this section 2.6(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, action or proceeding if
such settlement is effected without the consent of such seller (which consent
shall not be unreasonably withheld).  The parties hereto hereby acknowledge and
agree that, unless otherwise expressly agreed to in writing by holders of
Registrable Securities to the contrary, for all purposes of this Agreement the
only information furnished or to be furnished to the Company for use in any
registration statement, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto are
statements specifically relating to (i) the beneficial ownership of shares of
Common Stock by such holders and its Affiliates, (ii) the name and address of
such holder and (iii) the method or methods of distribution of such holders.
The indemnity provided for under this section 2.6(b) shall be limited in


                                      17


amount to the net amount of proceeds actually received by such seller from the
sale of Registrable Securities pursuant to such registration statement.

          (c) Notices of Claims, etc.  Promptly after receipt by an indemnified
              ----------------------
party of notice of the commencement of any action or proceeding involving a
claim referred to in the preceding subsections of this section 2.6, such
indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of
such action, provided that the failure of any indemnified party to give notice
             --------
as provided herein shall not relieve the indemnifying party of its obligations
under the preceding subsections of this section 2.6, except to the extent that
the indemnifying party is actually prejudiced by such failure to give notice.
In case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist in respect of such claim, the
indemnifying party shall be entitled to participate in and to assume the defense
thereof, jointly with any other indemnifying party similarly notified, to the
extent that the indemnifying party may wish, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party shall not be liable to such indemnified party
for any legal or other expenses subsequently incurred by the latter in
connection with the defense thereof other than reasonable costs of
investigation.  No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
of any such action 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, or a covenant not to sue, in respect to such claim or litigation.
No indemnified party shall consent to entry of any judgment or enter into any
settlement of any such action the defense of which has been assumed by an
indemnifying party without the consent of such indemnifying party, which consent
shall not be unreasonably withheld.

          (d) Indemnification Payments.  The indemnification required by this
              ------------------------
section 2.6 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or
expense, loss, damage or liability is incurred.

          (e) Contribution.  If the indemnification provided for in the
              ------------
preceding subsections of this section 2.6 is unavailable to an indemnified party
in respect of any expense, loss, claim, damage or liability referred to therein,
then each

                                      18


indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such expense, loss, claim, damage or liability in such proportion as is
appropriate to reflect the relative benefits and the relative fault of the
Company on the one hand and the holder or underwriter, as the case may be, on
the other in connection with the distribution of the Registrable Securities and
the statements or omissions which result in any expense, loss, damage or
liability, as well as any other relevant equitable considerations. The relative
fault of the Company on the one hand and of the holder or underwriter, as the
case may be, on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or
omission to state a material fact relates to information supplied by the
Company, by the holder or by the underwriter and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          The Company and the holders of Registrable Securities agree that it
would not be just and equitable if contribution pursuant to this subsection (e)
were determined by pro rata allocation (even if the holders and any underwriters
                   --- ----
were treated as one entity for such purpose) or by any other method of
allocation that does not take account of the equitable considerations referred
to in the immediately preceding paragraph.  The amount paid or payable by an
indemnified party as a result of the losses, claims, damages and liabilities
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth in the preceding sentence and subsection
(c) of this section 2.6, any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim.

          Notwithstanding the provisions of this subsection (e), no holder of
Registrable Securities or underwriter shall be required to contribute any amount
in excess of the amount by which (i) in the case of any such holder the net
proceeds actually received by such holder from the sale of Registrable
Securities or (ii) in the case of an underwriter, the total price at which the
Registrable Securities purchased by it and distributed to the public were
offered to the public exceeds, in any such case, the amount of any damages that
such holder or underwriter has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission.  No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  No party shall be liable for contribution under
this section 2.6 except to the extent and under such circumstances as such

                                      19


party would have been liable to indemnified under this section 2.6 if such
indemnification were enforceable under applicable law.

              2.7  Limitations on Registrations of Registrable Securities.  The
                   ------------------------------------------------------
Company shall not be required to effect any registration of Registrable
Securities pursuant to section 2.l or 2.2 hereof (other than with respect to a
registration pursuant to section 2.l of Registrable Securities of the Initiating
Holders) if it shall deliver (i) to the requesting holder of Registrable
Securities an opinion of counsel (which opinion and counsel shall be reasonably
satisfactory to the Initiating Holders, or other requesting holder of
Registrable Securities, if applicable) to the effect that all Registrable
Securities held by such Initiating Holders, or other requesting holder of
Registrable Securities, if applicable, may be sold immediately in the public
market without registration under the Securities Act and any applicable state
securities laws and (ii) to the Company's stock transfer agent a letter of
instruction removing any stop order and restrictive legends on such Registrable
Securities.
