for distribution in accordance with such intended method of distribution, and

                    2.1.4.1  the Company shall not be obligated to cause a
     Demand Registration to become effective for greater than the twenty five
     percent (25%) of the total number of shares of Registrable Securities held
     by all of the Acorn Holders;

                    2.1.4.2  the Company shall have the sole discretion pursuant
     to Section 2.2.4 of the Purchase Agreement to provide in lieu of a Demand
     Registration hereunder (i) a loan with a term of three (3) years, bearing
     fixed simple interest at the prime rate reported on the date of the loan in
     the "Money Rates" section of the Wall Street Journal (or if such rate is
                                      -------------------
     not published, a comparable rate of Citibank, N.A. ("Prime Rate") amortized
     in equal monthly payments in an amount equal to up to twenty-five percent

     25% of the Registrable Securities held by the requesting Acorn Holders; or
     (ii) an offer to repurchase twenty-five percent (25%) of the Registrable
     Securities held by the requesting Acorn Holders at fair market value as of
     such date.

                    2.1.4.3  the Company shall not be obligated to cause a
     Demand Registration to become effective within six months after the
     effective date of any other registration of securities (other than pursuant
     to a registration on Form S-8 or any successor or similar form that is then
     in effect),

                    2.1.4.4  (except as set forth below) in no event shall the
     Company be required to effect, in the aggregate, without regard to the
     Acorn Holder of Registrable Securities making such request, more than one
     Demand Registration (it being agreed that any Demand Registration that does
     not become effective shall not count toward the foregoing limitation unless
     at the request of the Requisite Percentage of Participating Holders, such
     Demand Registration has been withdrawn after the relevant registration
     statement has been filed but prior to it becoming effective); and

                    2.1.4.5  the Company shall not be obligated to effect a
     Demand Registration having an aggregate anticipated offering price of less
     than $150,000 unless such offering shall cover all remaining Registrable
     Securities. Notwithstanding any other provision of this Section 2.1.4.5,
     any Acorn Holder participating in a Demand

<PAGE>

     Registration who is unable to register all of the Registrable Securities
     that such Acorn Holder sought to register because of the "cutback"
     provision set forth in Section 2.1.5 shall be entitled to an additional
     Demand Registration solely with respect to such Acorn Holder's shares of
     Registrable Securities not registered because of the proviso in Section
     2.1.5, and such additional Demand Registration shall not count toward the
     one Demand Registration contemplated in Section 2.1.4.4.

                    2.1.4.6  the Company shall not be obligated to effect a
     Demand Registration requested later than three (3) months prior to the date
     on which the Acorn Holders must pay tax for the receipt of the Registrable
     Securities.

            2.1.5   Underwriter Cutbacks.  If the managing underwriter of any
                    --------------------
underwritten offering shall advise the Acorn Holders participating in a Demand
Registration that the Registrable Securities covered by the registration
statement cannot be sold in such offering within a price range acceptable to the
Requisite Percentage of Participating Holders, then the Acorn Holders
representing the Requisite Percentage of Participating Holders shall have the
right to notify the Company in writing that they have determined that the
registration statement be abandoned or withdrawn, in which event the Company
shall abandon or withdraw such registration statement.  If the managing
underwriter of any underwritten offering shall advise the Company in writing
that, in its opinion, the number of securities requested to be included in a
Demand Registration exceeds the number that can be sold in such offering within
a price range acceptable to the Requisite Percentage of Participating Holders,
the Company will include in such registration, to the extent of the number that
the Company is so advised can be sold in such offering, Registrable Securities
requested to be included in such registration, pro rata among the Acorn Holders
requesting such registration in accordance with the number of Registrable
Securities held by each such Acorn Holder; provided, however, that if, pursuant
                                           --------  -------
to any of the Other Registration Rights Agreements, the parties holding Other
Registrable Securities exercise "piggy-back" rights in connection with a Demand
Registration that is governed by the general provisions of this sentence, then
the Company will include in such registration, to the extent of the number that
the Company is so advised can be sold in such offering, first all Registrable
                                                        -----
Securities requested to be so included and after all such Registrable Securities
are so included, second, Other Registrable Securities requested to be included
                 ------
in such registration, pro rata among the Acorn Holders and the holders of such
Other Registrable Securities participating in such offering in accordance with
(i) with respect to Acorn Holders, the number of Registrable Securities held by
such Acorn Holder and (ii) with respect to holders of Other Registrable
Securities, the number of shares of Other Registrable Securities held by and, if
applicable, issuable upon conversion of any other securities of the Company
convertible into, exchangeable for or exercisable for Common Stock to each such
holder.

            2.1.6   Selection of Underwriters.  The managing underwriter or
                    -------------------------
underwriters of each underwritten offering of the Registrable Securities so to
be registered shall be selected by the Company.

            2.1.7   Postponement; Suspension.  The Company shall be entitled to
                    ------------------------
postpone or suspend for a reasonable period of time (but not to exceed, in the
aggregate, 90 days in any 365 day period) the filing or effectiveness of any
registration statement required to be prepared and filed by it pursuant to this
Section 2.1 if, (i) the postponement or suspension is necessary due to
circumstances that would require disclosure that would materially and adversely
affect a material acquisition, divestiture or financial transaction of the
Company or (ii) such postponement or suspension is necessary to prepare
financial statements of an acquired company required to be included in such
registration statement pursuant to the requirements of Regulation S-X of the
SEC.  The Company shall give the participating Acorn Holders prompt written
notice of its determination to postpone or suspend the filing of any
registration statement, and an approximation of the anticipated delay.  If the
Company shall so postpone or suspend the filing of a registration statement, the
participating Acorn Holders representing the Requisite Percentage of
Participating Holders shall have the right to withdraw the request for
registration by giving written notice to the Company within 20 days after
receipt of the notice of postponement or suspension (as the case may be) and, in
the event of such withdrawal, such request shall not be counted toward the
number of Requested Registrations (including for purposes of Section 2.1.4).

            2.1.8   Taxes.  If the proceeds to be received by an Acorn Holder
                    -----
participating in a Demand Registration hereunder would not exceed such Acorn
Holder's tax liability arising out of the receipt of his or her shares of
Registrable Securities under a registration statement filed pursuant to such
Demand Registration, the participating Acorn Holder shall notify the Company of
the amount of such tax obligation and the difference between the Acorn Holder's
tax obligation and the proceeds received by the Acorn Holder from the sale of
his or her shares of Registrable Securities under such registration statement
(the "Tax Shortfall").  Upon receipt of such notice, the Company shall offer to
      -------------
include in such Demand Registration up to an additional twenty five percent
(25%) of the total number of shares of Registrable Securities held by the
participating Acorn Holders, but in no event a greater number of shares of
Registrable Securities as having a fair market value greater than the amount of
the Tax Shortfall.

     2.2    Piggyback Registrations.
            -----------------------

            2.2.1   Piggyback Registrations. If, at any time, the Company
                    -----------------------
proposes or is required to register any of its equity securities under the
Securities Act (other than pursuant to registrations on such form or similar
form(s) solely for registration of securities in connection with an employee
benefit plan or dividend reinvestment plan or a merger, consolidation or
acquisition) on a registration statement on Form S-1, Form S-2 or Form S-3 (or
an equivalent general registration form then in effect), whether or not for its
own account, the Company shall

                                       7
<PAGE>

give prompt written notice of its intention to do so to Prospero. Upon the
written request of Prospero, made within 15 days following the receipt of any
such written notice (which request shall specify the maximum number of
Registrable Securities intended to be disposed of by Prospero and the intended
method of distribution thereof), the Company shall use its best efforts to cause
all such Registrable Securities, of which Prospero has so requested the
registration, to be registered under the Securities Act (with the securities
that the Company at the time it proposes to register) to permit the sale or
other disposition by Prospero (in accordance with the intended method of
distribution thereof) of the Registrable Securities to be so registered. There
is no limitation on the number of such piggyback registrations pursuant to the
preceding sentence that the Company is obligated to effect. No registration
effected under this Section 2.2.1 shall relieve the Company of its obligations
to effect Demand Registrations hereunder.

            2.2.2   Abandonment or Delay.  If, at any time after giving written
                    --------------------
notice of its intention to register any equity securities and prior to the
effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such equity securities, the Company may, at its election,
give written notice of such determination to Prospero and (i) in the case of a
determination not to register, shall be relieved of its obligation to register
any Registrable Securities of Prospero in connection with such abandoned
registration, without prejudice, however, to the rights of Holders under Section
2.1, and (ii) in the case of a determination to delay such registration of its
equity securities, shall be permitted to delay the registration of such
Registrable Securities for the same period as the delay in registering such
other equity securities.

            2.2.3   Right to Withdraw. Prospero shall have the right to withdraw
                    -----------------
its request for inclusion of its Registrable Securities in any registration
statement pursuant to this Section 2.2 by giving written notice to the Company
of its request to withdraw; provided, however, that (i) such request must be
                            --------  -------
made in writing prior to the earlier of the execution of the underwriting
agreement or  the execution of the custody agreement with respect to such
registration and (ii) such withdrawal shall be irrevocable and, after making
such withdrawal, Prospero shall no longer have any right to include Registrable
Securities in the registration as to which such withdrawal was made.

            2.2.4   Cutbacks.  If the managing underwriter of any underwritten
                    --------
offering shall inform the Company by letter of its belief that the number of
Registrable Securities requested to be included in a registration under this
Section 2.2 would materially adversely affect such offering, then the Company
will include in such registration, first, the securities proposed by the Company
                                   -----
to be sold for its own account and, second, the Registrable Securities and all
                                    ------
other securities of the Company to be included in such registration to the
extent of the number and type, if any, that the Company is so advised can be
sold in (or during the time of) such offering, first, pro rata among Prospero
                                               -----
and the holders of Other Registrable Securities under any of the Other
Registration Rights Agreements participating in such offering in accordance with
(i) with

                                       8
<PAGE>

respect to Prospero, the number of shares of Registrable Securities held by
Prospero, and (ii) with respect to holders of Other Registrable Securities, the
number of Other Registrable Securities held by, and if applicable, issuable upon
conversion of securities convertible into, exchangeable or exercisable for,
shares of Common Stock, to each such holder, and second, pro rata among the
                                                 ------
holders of any other securities of the Company with respect to which the holders
thereof are entitled to and desire "piggy-back" or similar registration rights;
provided, however, that if such registration is effected by the Holders pursuant
--------  -------
to Section 2.1 herein, Section 2.1.5 shall govern the determination of
Registrable Securities and Other Registrable Securities to be included in such
registration.

     2.3    Registration Procedures.  If and whenever the Company is required by
            -----------------------
the provisions of this Agreement to use its best efforts to effect or cause the
registration of any Registrable Securities under the Securities Act as provided
in this Agreement, the Company shall, as expeditiously as possible:

            2.3.1   prepare and file with the SEC a registration statement on an
appropriate registration form of the SEC for the disposition of such Registrable
Securities in accordance with the intended method of disposition thereof, which
form (i) shall be selected by the Company and (ii) shall, in the case of a shelf
registration, be available for the sale of the Registrable Securities by the
selling Holders thereof and such registration statement shall comply as to form
in all material respects with the requirements of the applicable form and
include all financial statements required by the SEC to be filed therewith, and
the Company shall use its best efforts to cause such registration statement to
become effective (provided, however, that before filing a registration statement
                  --------
or prospectus or any amendments or supplements thereto, or comparable statements
under securities or blue sky laws of any jurisdiction, the Company will furnish
to counsel for the underwriters, if any, copies of all such documents proposed
to be filed (including all exhibits thereto), which documents will be subject to
the reasonable review and reasonable comment of such counsel, and the Company
shall not file any registration statement or amendment thereto or any prospectus
or supplement thereto to which the holders of a majority of the Registrable
Securities covered by such registration statement or the underwriters, if any,
shall reasonably object in writing);

            2.3.2   prepare and file with the SEC 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
such period (which shall not be required to exceed 90 days) as any seller of
Registrable Securities pursuant to such registration statement shall request and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all Registrable Securities covered by such registration
statement in accordance with the intended methods of disposition by the seller
or sellers thereof set forth in such registration statement;

            2.3.3   furnish, without charge, to each seller of such Registrable
Securities and each underwriter, if any, of the securities covered by such
registration statement such number of copies of such registration statement,
each amendment and supplement thereto (in each case including all exhibits), and
the prospectus included in such registration statement (including each
preliminary prospectus) in conformity with the requirements of the Securities
Act, and other documents, as such seller and underwriter may reasonably request
in order to facilitate the public sale or other disposition of the Registrable
Securities owned by such seller (the Company hereby consenting to the use in
accordance with applicable law of each such registration statement (or amendment
or post-effective amendment thereto) and each such prospectus (or preliminary
prospectus or supplement thereto) by each such seller of Registrable Securities
and the underwriters, if any, in connection with the offering and sale of the
Registrable Securities covered by such registration statement or prospectus);

            2.3.4   use its best efforts to register and qualify the Registrable
Securities covered by such registration statement under such other securities or
"blue sky" laws of such jurisdictions as any sellers of Registrable Securities
or any managing underwriter, if any, shall reasonably request in writing, and do
any and all other acts and things that may be reasonably necessary or advisable
to enable such sellers or underwriter, if any, to consummate the disposition of
the Registrable Securities in such jurisdictions, except that in no event shall
the Company be required to qualify to do business as a foreign corporation in
any jurisdiction where it would not, but for the requirements of this Section,
be required to be so qualified, to subject itself to taxation in any such
jurisdiction or to consent to general service of process in any such
jurisdiction;

            2.3.5   promptly notify each Holder selling Registrable Securities
covered by such registration statement and each managing underwriter, if any:
(i) when the registration statement, any pre-effective amendment, 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, when the same has become effective;
(ii) of any request by the SEC or state securities authority for amendments or
supplements to the registration statement or the prospectus related thereto or
for additional information; (iii) of the issuance by the SEC of any stop order
suspending the effectiveness of the registration statement or the initiation of
any proceedings for that purpose; (iv) 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 of any proceeding for such purpose; (v) of the
existence of any fact of which the Company becomes aware that results in the
registration statement, the prospectus related thereto or any document
incorporated therein by reference containing an untrue statement of a material
fact or omitting to state a material fact required to be stated therein or
necessary to make any statement therein not misleading; and (vi) if at any time
the representations and warranties contemplated by ARTICLE III below cease to be
true and correct in all material respects; and, if

                                       10
<PAGE>

the notification relates to an event described in clause (v), the Company shall
promptly prepare and furnish to each such seller and each underwriter, if any, a
reasonable number of copies of a prospectus supplemented or amended so that, as
thereafter delivered to the purchasers of such Registrable 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 in the light of the circumstances under which they were made
not misleading;

            2.3.6   comply with all applicable rules and regulations of the SEC,
and make generally available to its security holders, as soon as reasonably
practicable after the effective date of the registration statement (and in any
event within 16 months thereafter), an earnings statement (which need not be
audited) covering the period of at least twelve consecutive months beginning
with the first day of the Company's first calendar quarter after the effective
date of the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

            2.3.7   enter into such customary agreements (including, if
applicable, an underwriting agreement) and take such other actions as the
Holders of a majority of the Registrable Securities participating in such
offering shall reasonably request in order to expedite or facilitate the
disposition of such Registrable Securities;

            2.3.8   use its best efforts to promptly obtain the withdrawal of
any order suspending the effectiveness of the registration statement;

            2.3.9   furnish to each Holder participating in the offering and the
managing underwriter, without charge, at least one signed copy of the
registration statement and any post-effective amendments thereto, including
financial statements and schedules, all documents incorporated therein by
reference and all exhibits (including those incorporated by reference);

            2.3.10  cooperate with the selling Holders of Registrable Securities
and the managing underwriter, if any, to facilitate the timely preparation and
delivery of certificates not bearing any restrictive legends representing the
Registrable Securities to be sold, and cause such Registrable Securities to be
issued in such denominations and registered in such names in accordance with the
underwriting agreement prior to any sale of Registrable Securities to the
underwriters or, if not an underwritten offering, in accordance with the
instructions of the selling holders of Registrable Securities at least three
business days prior to any sale of Registrable Securities; and

            2.3.11  take all such other commercially reasonable actions as are
necessary or advisable in order to expedite or facilitate the disposition of
such Registrable Securities.

                                       11
<PAGE>

          The Company may require as a condition precedent to the Company's
obligations under this Section 2.3 that each seller of Registrable Securities as
to which any registration is being effected furnish the Company such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request provided that such information shall be
used only in connection with such registration.

          Each Holder of Registrable Securities agrees that upon receipt of any
notice from the Company of the happening of any event of the kind described in
clauses (iii), (iv) or (v) of Section 2.3.5, such Holder will discontinue such
Holder's disposition of Registrable Securities pursuant to the registration
statement covering such Registrable Securities until such Holder's receipt of
the copies of the supplemented or amended prospectus contemplated by Section
2.3.5 and, if so directed by 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 covering such Registrable Securities that
was in effect at the time of receipt of such notice. In the event the Company
shall give any such notice, the applicable period mentioned in Section 2.3.2
shall be extended by the number of days during such period from and including
the date of the giving of such notice to and including the date when each seller
of any Registrable Securities covered by such registration statement shall have
received the copies of the supplemented or amended prospectus contemplated by
Section 2.3.5.

          If any such registration statement or comparable statement under "blue
sky" laws refers to any Holder by name or otherwise as the Holder of any
securities of the Company, then such Holder shall have the right to require (i)
the insertion therein of language, in form and substance satisfactory to such
Holder and the Company, to the effect that the holding by such Holder of such
securities is not to be construed as a recommendation by such Holder of the
investment quality of the Company's securities covered thereby and that such
holding does not imply that such Holder will assist in meeting any future
financial requirements of the Company, or (ii) in the event that such reference
to such Holder by name or otherwise is not in the judgment of the Company, as
advised by counsel, required by the Securities Act or any similar federal
statute or any state "blue sky" or securities law then in force, the deletion of
the reference to such Holder.

     2.4  Registration Expenses.
          ---------------------

          2.4.1 "Expenses" shall mean any and all fees and expenses incident to
the Company's performance of or compliance with this Article 2, including,
without limitation: (i) SEC, stock exchange or NASD registration, listing and
filing fees and all listing fees and fees with respect to the inclusion of
securities in NASDAQ, (ii) fees and expenses of compliance with state securities
or "blue sky" laws and in connection with the preparation of a "blue sky"
survey, including without limitation, reasonable fees and expenses of blue sky
counsel, (iii) printing and copying expenses, (iv) messenger and delivery
expenses, (v) expenses incurred in connection

                                       12
<PAGE>

with any road show, (vi) fees and disbursements of counsel for the Company,
(vii) fees and disbursements of all independent public accountants (including
the expenses of any audit and/or "cold comfort" letter) and fees and expenses of
other persons, including special experts, retained by the Company, (viii) fees
and expenses payable to a Qualified Independent Underwriter (as defined in NASD
Conduct Rule 2720(b)(15)), (ix) fees and expenses payable to the underwriters
referred to in Section 2.3.6 and (x) any other fees and disbursements of
underwriters, if any, customarily paid by issuers or sellers of securities
(collectively, "Expenses").
                --------

          2.4.2  The Company shall pay all Expenses with respect to any Demand
Registration whether or not it becomes effective or remains effective for the
period contemplated by Section 2.3.2 and with respect to up to one registration
effected under Section 2.2. Notwithstanding the foregoing, if, with respect to a
Demand Registration, at the request of the Requisite Percentage of Participating
Holders such registration has been withdrawn after the relevant registration
statement has been filed but prior to its becoming effective, then the Company,
on the one hand, and the Holders participating in such registration, on the
other hand, shall each bear one-half of the Expenses incurred by the Company in
connection with such registration, and any Expenses to be borne hereunder by
such Holders shall be borne by them pro rata in accordance with the number of
shares of Registrable Securities that, with respect to each such Holder, were
included in such registration.

          2.4.3  Notwithstanding the foregoing, (i) the provisions of this
Section 2.4 shall be deemed amended to the extent necessary to cause these
expense provisions to comply with "blue sky" laws of each state in which the
offering is made and (ii) in connection with any registration hereunder, each
Holder of Registrable Securities being registered shall pay all underwriting
discounts and commissions and any transfer taxes, if any, attributable to the
sale of such Registrable Securities, pro rata with respect to payments of
                                     --------
discounts and commissions in accordance with the number of shares sold in the
offering by such Holder, and (iii) the Company shall, in the case of all
registrations under this ARTICLE 2, be responsible for all its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties).

     2.5  Certain Limitations on Registration Rights.
          ------------------------------------------

          2.5.1  In the case of any registration under Section 2.1 pursuant to
an underwritten offering, or in the case of a registration under Section 2.2 if
the Company has determined to enter into an underwriting agreement in connection
therewith, all securities to be included in such registration shall be subject
to an underwriting agreement and no Person may participate in such registration
unless such Person agrees to sell such Person's securities on the basis provided
therein and completes and executes all reasonable questionnaires and other
documents (including custody agreements and powers of attorney) that must be
executed in

                                       13
<PAGE>

connection therewith, and provides such other information to the Company or the
underwriter as may be necessary to register such Person's securities.

          2.5.2  No Holder shall have any right to demand or participate in a
registration under this ARTICLE 2 if such Holder may sell twenty five percent
(25%) or more its Registrable Securities in a five (5) month period (such period
commencing on the date of the notice under Section 2.1.1 or 2.2.1, as the case
may be) under Rule 144 under the Securities Act.

     2.6  Limitations on Sale or Distribution of Other Securities.
          -------------------------------------------------------

          2.6.1  To the extent requested in writing by a managing underwriter,
if any, of any registration effected pursuant to Section 2.1, each Holder of
Registrable Securities agrees not to sell, transfer or otherwise dispose of,
including any sale pursuant to Rule 144 under the Securities Act, any
Registrable Securities (other than as part of such underwritten public offering)
during the time period reasonably requested by the managing underwriter, not to
exceed 180 days (and the Company hereby also so agrees (except that the Company
may effect any sale or distribution of any such securities pursuant to a
registration on Form S-4 (if reasonably acceptable to such managing underwriter)
or Form S-8, or any successor or similar form that is then in effect) to use its
reasonable best efforts to cause each holder of any equity security or any
security convertible into or exchangeable or exercisable for any equity security
of the Company purchased from the Company at any time other than in a public
offering so to agree). Each managing underwriter shall be entitled to rely on
the agreements of each Holder of Registrable Securities set forth in this
Section 2.6.1 and shall be a third party beneficiary of the provisions of this
Section 2.6.1.

          2.6.2  The Company hereby agrees that, if it shall previously have
received a request for registration pursuant to Section 2.1, and if such
previous registration shall not have been withdrawn or abandoned, the Company
shall not sell, transfer, or otherwise dispose of, any Common Stock, or any
other equity security of the Company or any security convertible into or
exchangeable or exercisable for any equity security of the Company (other than
as part of a private sale pursuant to a transaction for which Form S-4 would be
used if such sale were registered, an underwritten public offering pursuant to
such request for registration pursuant to Section 2.2, a registration on Form S-
4 or Form S-8 or any successor or similar form that is then in effect, upon the
conversion, exchange or exercise of any then outstanding Common Stock Equivalent
or in connection with the issuance or exercise of options pursuant to a stock
option plan or pursuant to an employee stock purchase plan), for a period of at
least 40 days commencing on the date 10 days prior to the effective date of such
previous registration, and the Company shall so provide in any registration
rights agreements hereafter entered into with respect to any of its securities.

                                       14
<PAGE>

     2.7  No Required Sale. Nothing in this Agreement shall be deemed to create
          ----------------
an independent obligation on the part of any Holder to sell any Registrable
Securities pursuant to any effective registration statement.

     2.8  Indemnification.
          ---------------

          2.8.1  In the event of any registration of any securities of the
Company under the Securities Act pursuant to this Article 2, the Company will,
and hereby does, indemnify and hold harmless, to the fullest extent permitted by
law, each Holder of Registrable Securities, its directors, officers, Affiliates,
employees, stockholders, members and partners (and the directors, officers,
Affiliates, employees, stockholders, members and partners thereof), each other
Person who participates as an underwriter or a Qualified Independent
Underwriter, if any, in the offering or sale of such securities, each officer,
director, employee, stockholder, member or partner of such underwriter or
Qualified Independent Underwriter, and each other Person, if any, who controls
such seller or any such underwriter within the meaning of the Securities Act,
against any and all losses, claims, damages or liabilities, joint or several,
actions or proceedings (whether commenced or threatened) in respect thereof
("Claims") and expenses (including reasonable fees of counsel and any amounts
  ------
paid in any settlement effected with the Company's consent, which consent shall
not be unreasonably withheld or delayed) to which each such indemnified party
may become subject under the Securities Act or otherwise, insofar as such Claims
or expenses arise out of or are based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in any registration statement
under which such securities were registered under the Securities Act, together
with the documents incorporated by reference therein or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary, final or summary prospectus or any amendment or supplement thereto,
together with the documents incorporated by reference therein, or the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading or (iii) any
violation or alleged violation by the Company of any federal, state or common
law, rule or regulation applicable to the Company and relating to action
required of or inaction by the Company in connection with any such registration;
provided, however, that the Company shall not be liable to any such indemnified
--------  -------
party in any such case to the extent such Claim or expense arises out of or is
based upon any untrue statement or alleged untrue statement of a material fact
or omission or alleged omission of a material fact made in such registration
statement or amendment thereof or supplement thereto or in any such prospectus
or any preliminary, final or summary prospectus in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such indemnified party specifically for use therein. Such indemnity and
reimbursement of expenses shall remain in full force and effect regardless of
any investigation made by or on behalf of such indemnified party and shall
survive the transfer of such securities by such seller.

                                       15
<PAGE>

          2.8.2  Each Holder of Registrable Securities that are included in the
securities as to which any registration under Section 2.1 or Section 2.2 is
being effected (and, if the Company requires as a condition to including any
Registrable Securities in any registration statement filed in accordance with
Section 2.1 or Section 2.2, any underwriter and Qualified Independent
Underwriter, if any) shall, severally and not jointly, indemnify and hold
harmless (in the same manner and to the same extent as set forth in Section
2.8.1) to the fullest extent permitted by law, on an after-tax basis, the
Company, its officers, directors, Affiliates, employees and stockholders,
members and partners (and the directors, officers, Affiliates, employees,
stockholders, members and partners thereof), each Person controlling the Company
within the meaning of the Securities Act and all other prospective sellers and
their directors, officers, general and limited partners and respective
controlling Persons with respect to any untrue statement or alleged untrue
statement of any material fact in, or omission or alleged omission of any
material fact from, such registration statement, any preliminary, final or
summary prospectus contained therein, or any amendment or supplement thereto, in
each case, to the extent (and only to the extent) that 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 or its
representatives by or on behalf of such Holder (or underwriter or Qualified
Independent Underwriter, if any), specifically for use therein and Holder shall
reimburse such indemnified party for any legal or other expenses reasonably
incurred in connection with investigating or defending any such Claim as such
expenses are incurred; provided, however, that the aggregate amount that any
                       --------  -------
such Holder shall be required to pay pursuant to this Section 2.8.2 and Sections
2.8.3 and 2.8.5 shall in no case be greater than the amount of the net proceeds
received by such person upon the sale of the Registrable Securities pursuant to
the registration statement giving rise to such claim. Such indemnity and
reimbursement of expenses shall remain in full force and effect regardless of
any investigation made by or on behalf of such indemnified party and shall
survive the transfer of such securities by such Holder.

          2.8.3  Indemnification similar to that specified in Sections 2.8.1 and
2.8.2 (with appropriate modifications) shall be given by the Company and each
seller of Registrable Securities with respect to any required registration or
other qualification of securities under any state securities and "blue sky"
laws.

          2.8.4  Any person entitled to indemnification under this Agreement
shall notify promptly the indemnifying party in writing of the commencement of
any action or proceeding with respect to which a claim for indemnification may
be made pursuant to this Section 2.8, but the failure of any indemnified party
to provide such notice shall not relieve the indemnifying party of its
obligations under the preceding paragraphs of this Section 2.8, except to the
extent the indemnifying party is materially prejudiced thereby and shall not
relieve the indemnifying party from any liability which it may have to any
indemnified party otherwise than under this ARTICLE 2. In case any action or
proceeding is brought against an indemnified party and it

                                       16
<PAGE>

shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate therein and, unless in the
reasonable opinion of outside counsel to the indemnified party a conflict of
interest between such indemnified and indemnifying parties may exist in respect
of such claim, to assume the defense thereof jointly with any other indemnifying
party similarly notified, to the extent that it chooses, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party that it so chooses, the indemnifying party shall
not be liable to such indemnified party for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
                                                      --------  -------
(i) if the indemnifying party fails to take reasonable steps necessary to defend
diligently the action or proceeding within 20 days after receiving notice from
such indemnified party that the indemnified party believes it has failed to do
so; or (ii) if such indemnified party who is a defendant in any action or
proceeding that is also brought against the indemnifying party reasonably shall
have concluded that there may be one or more legal defenses available to such
indemnified party that are not available to the indemnifying party; or (iii) if
representation of both parties by the same counsel is otherwise inappropriate
under applicable standards of professional conduct, then, in any such case, the
indemnified party shall have the right to assume or continue its own defense as
set forth above (but with no more than one firm of counsel for all indemnified
parties in each jurisdiction), and the indemnifying party shall be liable for
any expenses therefor. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (A)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (B) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

          2.8.5  If for any reason the foregoing indemnity is unavailable or is
insufficient to hold harmless an indemnified party under Sections 2.8.1, 2.8.2
or 2.8.3, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of any Claim in such proportion as
is appropriate to reflect the relative fault of the indemnifying party, on the
one hand, and the indemnified party, on the other hand, with respect to such
offering of securities. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the indemnifying party or the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. If, however, the
allocation provided in the second preceding sentence is not permitted by
applicable law, then each indemnifying party shall contribute to the amount paid
or payable by such indemnified party in such proportion as is appropriate to
reflect not only such relative faults but also the relative

                                       17
<PAGE>

benefits of the indemnifying party and the indemnified party as well as any
other relevant equitable considerations. The parties hereto agree that it would
not be just and equitable if contributions pursuant to this Section 2.8.5 were
to be determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to in the
preceding sentences of this Section 2.8.5. The amount paid or payable in respect
of any Claim shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such Claim. 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. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the violation relates to information supplied by the indemnifying party
or by the indemnified party and the parties' relative intent, knowledge, access
to information, and opportunity to correct or prevent such statement or
omission. Notwithstanding anything in this Section 2.8.5 to the contrary, no
indemnifying party (other than the Company) shall be required pursuant to this
Section 2.8.5 to contribute any amount in excess of the net proceeds received by
such indemnifying party from the sale of Registrable Securities in the offering
to which the losses, claims, damages or liabilities of the indemnified parties
relate, less the amount of any indemnification payment made by such indemnifying
party pursuant to Sections 2.8.2 and 2.8.3.

          2.8.6  The indemnity agreements contained herein shall be in addition
to any other rights to indemnification or contribution that any indemnified
party may have pursuant to law or contract and shall remain operative and in
full force and effect regardless of any investigation made or omitted by or on
behalf of any indemnified party and shall survive the transfer of the
Registrable Securities by any such party.

          2.8.7  The indemnification and contribution required by this Section
2.8 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.

                                  ARTICLE III
                            UNDERWRITTEN OFFERINGS

     3.1  Requested Underwritten Offerings. If requested by the underwriters
          --------------------------------
for any underwritten offering by the Acorn Holders pursuant to a registration
requested under Section 2.1, the Company shall enter into a customary
underwriting agreement with the underwriters. Such underwriting agreement shall
contain such representations and warranties by, and such other agreements on the
part of, the Company and such other terms as are generally included in the
standard underwriting agreement of such underwriters, including, without
limitation, indemnities and contribution agreements. Any Holder participating in
the offering shall be a

                                       18
<PAGE>

party to such underwriting agreement and shall make such representations and
warranties by the participating Holders as are customary in agreements of that
type.

     3.2  Piggyback Underwritten Offerings. In the case of a registration
          --------------------------------
pursuant to Section 2.2 hereof, if the Company shall have determined to enter
into an underwriting agreement in connection therewith, all of the Holders of
Registrable Securities to be included in such registration shall be subject to
such underwriting agreement. Any Holder participating in such registration may,
at its option, require 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 Holder 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 Holder. Such underwriting agreement shall also contain such

                                    GENERAL

     4.1  Rule 144. If the Company shall have filed a registration statement
          --------
pursuant to the requirements of Section 12 of the Exchange Act or a registration
statement pursuant to the requirements of the Securities Act in respect of the
Common Stock or securities of the Company convertible into or exchangeable or
exercisable for Common Stock, the Company covenants that (i) so long as it
remains subject to the reporting provisions of the Exchange Act, it will timely
file the reports required to be filed by it under the Securities Act or the
Exchange Act (including, but not limited to, the reports under Sections 13 and
15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 under
the Securities Act), and (ii) will take such further action as any Holder of

time to time to enable such Holder to sell Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by (A) Rule 144 under the Securities Act, as such Rule may be amended
from time to time, or (B) any similar rule or regulation hereafter adopted by
the Commission. Upon the request of any Holder of Registrable Securities, the
Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

accordance with the provisions of the Purchase Agreement shall not be deemed an
amendment hereof and shall not require the consent of any party hereto.

of and be enforceable by the parties hereto and the respective successors,
personal representatives and assigns of the parties hereto, whether so expressed
or not. If any Person shall acquire Registrable Securities from any Holder, in

promptly notify the Company and such Registrable Securities acquired from such
Holder shall be held subject to all of the terms of this Agreement, and by
taking and holding such Registrable Securities such Person shall be entitled to
receive the benefits of and be conclusively deemed to have agreed to be bound by
and to perform all of the terms and provisions of this Agreement. If the Company
shall so request, any such successor or assign shall agree in writing to acquire
and hold the Registrable Securities acquired from such Holder subject to all of
the terms hereof. If any Holder shall acquire additional Registrable Securities,
such Registrable Securities shall be subject to all of the terms, and entitled
to all the benefits, of this Agreement.

                                       21
<PAGE>

No Person other than a Holder shall be entitled to any benefits under this
Agreement, except as otherwise expressly provided herein.

          4.5.2  This Agreement (with the documents referred to herein or
delivered pursuant hereto) embodies the entire agreement and understanding
between the parties hereto and supersedes all prior agreements and
understandings relating to the subject matter hereof.

          4.5.3  This Agreement shall be construed and enforced in accordance
with and governed by the laws of the State of Colorado without giving effect to
the conflicts of law principles thereof.

          4.5.4  The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof. All section
references are to this Agreement unless otherwise expressly provided.

          4.5.5  This Agreement may be executed in any number of counterparts,
each of which shall be an original, but all of which together shall constitute
one instrument.

          4.5.6  Any term or provision of this Agreement that is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such invalidity or unenforceability without rendering invalid
or unenforceable the remaining terms and provisions of this Agreement or
affecting the validity or enforceability of any of the terms or provisions of
this Agreement in any other jurisdiction.

          4.5.7  The parties hereto acknowledge that there would be no adequate
remedy at law if any party fails to perform any of its obligations hereunder,
and accordingly agree that each party, in addition to any other remedy to which
it may be entitled at law or in equity, shall be entitled to seek injunctive
relief, including specific performance, to enforce such obligations without the
posting of any bond.

          4.5.8  Each party hereto shall take all such action necessary to cause
each certificate of the Company's securities to bear the following legend:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
          REGISTRATION RIGHTS AGREEMENT, BY AND AMONG INTEK INFORMATION, INC.
          AND CERTAIN OTHER PARTIES DATED OCTOBER 30, 1999, COPIES OF WHICH ARE
          AVAILABLE AT THE OFFICES OF INTEK INFORMATION, INC.

          4.5.9  Each party hereto shall do and perform or cause to be done and
performed all such further acts and things and shall execute and deliver all
such other agreements, certificates, instruments, and documents as any other
party hereto reasonably may request in
