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

     In order to induce the Purchasers to purchase the Purchased Shares, the
Company makes the following representations and warranties to each of the
Purchasers, which representations and warranties shall be true, correct and
complete in all respects on the date hereof and shall be true, correct and
complete in all respects as of the Closing:

     2.1  Organization and Corporate Power.  (a) The Company is a corporation
          --------------------------------
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation as set forth on Schedule 2.1(a) and has all
                                                  ---------------
requisite corporate power and authority to own its properties and to carry on
its business as presently conducted.  Except as set forth in Schedule 2.1(a),
                                                             ---------------
the Company is duly licensed or qualified to do business as a foreign
corporation in each jurisdiction wherein the character of its property, or the
nature of the activities presently conducted by it, makes such qualification
necessary or is otherwise required by law, each of which foreign jurisdictions
is set forth on Schedule 2.1 hereto.
                ------------

          (b) The attached Schedule 2.1(b) contains a list of all Subsidiaries
                           ---------------
of the Company.  Except for such Subsidiaries, the Company does not (i) own of
record or beneficially, directly or indirectly, (A) any shares of capital stock
or securities convertible into capital stock of any other corporation or (B) any
participating interest in any partnership, joint venture or other non-corporate
business enterprise or (ii) control, directly or indirectly, any other entity.
As used in this Agreement, unless otherwise specified, the term "Company" shall
                                                                 -------
mean the Company and each of its Subsidiaries.  Where the representations and
warranties apply in this Article II in any particular instance to a Subsidiary
of the Company, the Company and the Subsidiary, jointly and severally, make the
representations and warranties on behalf of such Subsidiary (as they apply to
such Subsidiary and as the context requires).

          (c) Each of the Subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
incorporation and is duly licensed or qualified to do business as a foreign
corporation in each jurisdiction wherein the nature of the business transacted
by it or the character of the properties owned or leased by it

                                      -2-
<PAGE>

requires such licensing or qualification. Each of the Subsidiaries has the
corporate power and authority to own and hold its properties and to carry on its
business as now conducted and as proposed to be conducted. All of the
outstanding shares of capital stock of each of the Subsidiaries are owned
beneficially and of record by the Company, one of its other wholly owned
Subsidiaries, or any combination of the Company and/or one or more of its other
wholly owned Subsidiaries, in each case free and clear of any liens, charges,
restrictions, claims or encumbrances of any nature whatsoever; and there are no
outstanding subscriptions, warrants, options, convertible securities, or other
rights (contingent or other) pursuant to which any of the Subsidiaries is or may
become obligated to issue any shares of its capital stock to any person other
than the Company or one of the other Subsidiaries.

     2.2.  Authorization. The Company has all necessary corporate power and has
           ---------------------------
taken all necessary corporate action required for the due authorization,
execution, delivery and performance by the Company of this Agreement, the Non-
Competition, Non-Disclosure and Confidentiality Agreements referenced in Section
8.8 and the Second Amended and Restated Shareholders' Agreement dated the date
hereof (the "Shareholders' Agreement") and referenced in Section 8.9
             -----------------------
(collectively, the "Related Agreements"), and any other agreements or
                    ------------------
instruments executed by the Company in connection herewith or therewith and the
consummation of the transactions contemplated herein or therein, and for the due
authorization, issuance and delivery of the Purchased Shares and the Conversion
Shares. Sufficient shares of authorized but unissued Common Stock have been
reserved for the issuance of the Conversion Shares issuable upon conversion of
the Purchased Shares. The issuance of the Purchased Shares does not, and the
issuance of the Conversion Shares will not, require any further corporate action
and is not and will not be subject to any preemptive right, right of first
refusal or the like. This Agreement, the Related Agreements and the other
agreements and instruments executed by the Company in connection herewith or
therewith will each be a valid and binding obligation of the Company enforceable
in accordance with its respective terms.

      2.3  Government Approvals.  No consent, approval, license or authorization
           --------------------
of, or designation, declaration or filing with, any court or governmental
authority is or will be required on the part of the Company in connection with
the execution, delivery and performance by the Company of this Agreement, any of
the Related Agreements or any other agreements or instruments executed by the
Company in connection herewith or therewith, or in connection with the sale and
issuance of the Purchased Shares or the issuance of the Conversion Shares,

-------
exclude any Observer from any meeting or portion thereof (so long as the Company
notifies the Observer of such withholding and of any action taken by the Board
of Directors as a result of such meeting) if access to such information or
attendance at such meeting would, (a) in the judgment of the Company's outside
counsel, adversely affect the attorney-client privilege between the Company and
its counsel or cause the Board of Directors to breach its fiduciary duties, (b)
in the good faith determination of a majority of the members of the Board of
Directors, will result in a conflict of interest with the Company due to such
Observer's relationships with any Purchaser of their affiliates, or (c) in the
good faith judgment of the management of the Company, would lead to disclosure
of trade secrets or confidential information of the Company or (d) not permit
the members of the Board of Directors, in order to satisfy their respective
fiduciary duties, to discuss without reservation a topic (or avoid disclosure of
information on such topic) which the Board of Directors reasonably believes
could result in a conflict of interest between the Company and any Observer,
stockholder or director representative. The Company will use its best efforts to
ensure that any withholding of information or any restriction on attendance is
strictly limited only to the extent necessary set forth in the preceding
sentence. The Observer shall not be (a) permitted to vote at any meeting of the
Board of Directors, or (b) counted for purposes of determining whether there is
sufficient quorum for the Board of Directors to conduct its business. The
parties hereto hereby acknowledge and agree that notwithstanding contrary
authority, if any, that no Observer shall owe any fiduciary or other duties to
the shareholders of the Company or otherwise have any directorial or other
duties or liabilities to the Company or its shareholders except as specifically
set forth in this Section 3.10. Each Purchaser entitled to an Observer shall
designate, and may replace, such Observer with or without cause in its sole

A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock or other shares of Common Stock which

          ----------------------------    --------------
capital stock of the Company whether now authorized or not, and rights, options
or warrants to purchase capital stock, and securities of any type whatsoever
that are, or may become convertible into or exchangeable for capital stock,

     5.4  Notice from the Company.  In the event the Company proposes to
          -----------------------
undertake an issuance of New Securities, it shall give each Purchaser written
notice of its intention, describing the type of New Securities and the price and
the terms upon which the Company proposes to issue the same. Each Purchaser
shall have twenty (20) business days from the date of receipt of any such notice
to agree to purchase up to their Pro Rata Share of such New Securities (and any
over-allotment amount pursuant to the operation of Section 5.2 hereof) for the
price and upon the terms specified in the notice by giving written notice to the
Company and stating therein the quantity of New Securities to be purchased.

     5.5  Sale by the Company.  In the event any Purchaser fails to exercise
          -------------------
in full his or its purchase right (after giving effect to the over-allotment
provision of Section 5.2 hereof), the Company shall have ninety (90) days
thereafter to sell the New Securities with respect to which such Purchaser's
purchase right was not exercised, at a price and upon terms no more favorable to
the purchasers thereof than was specified in the Company's notice. To the extent
the Company does not sell all the New Securities offered within said (90) day
period, the Company shall not thereafter issue or sell such New Securities
without first again offering such securities to each Purchaser in the manner
provided above.

     5.6  Termination of Rights.  The rights granted under this Article V
          ---------------------
shall expire immediately prior to, and shall not apply in connection with, the
consummation of the first Qualified Public Offering.

     5.7  Right to Purchase in Initial Public Offering.  With respect to the
          --------------------------------------------
initial public offering of the Company (the "IPO"), which shall be a firm
                                             ---
commitment underwritten public offering, those Series E Purchasers (together
with their affiliated entities) which are purchasing at least 75,000 shares of
Series E Preferred Stock (a "Qualified Purchaser") shall have the right to
purchase in such IPO up to an aggregate of ten percent (10%) of the shares of
Common Stock offered by the Company for sale to the public (the "IPO
                                                                 ---
Allocation"); provided that such participation in the IPO Allocation shall be
----------
subject to the same terms and conditions, including price and underwriting
terms, offered to the public, as any shares of Common Stock offered by the
Company to the public.  Notwithstanding the foregoing, the allocation of shares
to each Qualified Purchaser  under this Section 5.7 shall in all cases be
subject to (i) compliance with all applicable rules and regulation of, and if
necessary, approval by, the Commission and the National Association of
Securities Dealers (the "NASD") and any other law, policy, rule or regulation
                         ----
applicable to the IPO; and (ii) the delivery to the Company and any underwriters
of an opinion of counsel that such allocation is permissible by law, regulation
or policy of the Commission and/or the NASD. If any modification of the
provisions of this Section 5.7 becomes necessary due to the application to the
IPO of any such Commission or NASD law, rule, regulation or policy, the
provisions of this Section 5.7 shall be deemed automatically modified to give
effect to the maximum extent allowable under such law, policy, rule or
regulation. The application of the foregoing right of the IPO Allocation shall
be subject in all instances to the discretion of the managing underwriter in any
public offering, if such managing underwriter concludes that in its good faith
judgment the participation of the Qualified Purchasers would interfere with the
successful marketing (including pricing and flotation) of the securities to be
included in the Company's proposed public offering. For purposes of this Section
5.7, a

                                      -22-
<PAGE>

Qualified Purchaser also includes an investment company (or group of investment
companies) with a common investment advisor.

     The IPO Allocation shall be further allocated among the Qualified
Purchasers as follows: Crosslink Capital (together with its affiliated entities)
shall have the special right to obtain fifty percent (50%) of the IPO Allocation
and the balance of the IPO Allocation shall be divided among the rest of the
Qualified Purchasers on a "pro rata" basis. Such "pro rata" basis shall be
determined for each Qualified Purchaser (other than Crosslink Capital and its
affiliates) by a fraction, the numerator of which shall be all Conversion Shares
owned by each Qualified Purchaser (excluding for this purpose, Crosslink Capital
and its affiliates) and the denominator of which shall be the aggregate of all
Conversion Shares owned by all Qualified Purchasers (excluding for this purpose,
Crosslink Capital and its affiliates) desiring to participate in the IPO
Allocation.

     If the managing underwriter advises the Company that, in the managing
underwriter's good faith judgement, a limitation on the number of shares offered
pursuant to the IPO Allocation would interfere with the successful marketing
(including pricing and flotation) of the securities to be included in the
Company's proposed public offering, then Crosslink Capital shall participate
preferentially in the IPO Allocation up to the full amount of shares it would
otherwise be permitted to purchase (but for such limitation), and the balance,
if any, of shares remaining in the IPO Allocation shall be offered to the rest
of the Qualified Purchasers on a "pro rata" basis.

and not jointly, represents and warrants to the Company, as to itself only, as
follows with respect to the purchase of the Purchased Shares:

          (a)  Such Purchaser, if a corporation, partnership or trust, is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, has all requisite power and authority and has
taken all necessary action required for the due authorization, execution,
delivery and performance of this Agreement and the Related Agreements, and any

Purchaser, enforceable against such Purchaser in accordance with their
respective terms;

<PAGE>

          (c)  Such Purchaser has been advised and understands that the
Purchased Shares have not been registered under the Act, on the basis that no
distribution or public offering of the Purchased Shares is to be effected,
except in compliance with applicable securities laws and regulations or pursuant
to an exemption therefrom, and that, in this connection, the Company is relying
in part on the representations of such Purchasers set forth in this Article VI;

          (d)  Such Purchaser has been further advised and understands that no
public market now exists for any of the securities issued by the Company and
that a public market may never exist for the Purchased Shares or the Conversion
Shares;

          (e)  Such Purchaser is purchasing the Purchased Shares for investment
purposes, for its own account and not with a view to, or for sale in connection
with, any distribution thereof in violation of Federal or state securities laws;

          (f)  Such Purchaser is an "accredited investor" within the meaning of
Rule 501 under the Act and, by reason of its business or financial experience,
such Purchaser has the capacity to protect its own interest in connection with
the transactions contemplated hereunder;

          (g)  Such Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Purchased Shares;
provided, however, that nothing in this Section 6.1 shall be deemed to vitiate
or limit the representations, warranties and covenants of the Company contained
in this Agreement; and

          (h)  No person has or will have, as a result of the transaction
contemplated by this Agreement, any right, interest or claim against or upon the
Company for any commission, fee or other compensation as a finder or broker
because of any act or omission by such Purchaser; and

          (i)  Each Purchaser that is not an existing stockholder of the Company
and that is not a "venture capital operating company," within the meaning of DOL
Reg. Sec. 2510.3-101(d), hereby represents to the Company and the other
Purchasers that it is not investing in the Company with any "plan asset," within
the meaning of DOL Reg. Sec. 2510.3-101, of a "plan," within the meaning of
Section 3(3) of ERISA.

          6.2  Permitted Sales; Legends.  Notwithstanding the foregoing
               ------------------------
representations, the Company agrees that, if such transferee agrees in writing
to be subject to the terms hereof to the same extent as if it were an original
Purchaser hereunder, it will permit (a) a distribution of Preferred Stock or
Conversion Shares by a partnership to one or more of its partners, where no
consideration is exchanged therefor by such partners, or to a retired or
withdrawn partner who retires or withdraws after the date hereof in full or
partial distribution of his or her interest in such partnership, or to the
estate of any such partner or the transfer by gift, will or intestate succession
of any partner to his or her spouse or to the siblings, lineal descendants or
ancestors of such partner or his or her spouse, or to a trust created for the
benefit of one or more of the foregoing, (b) a transfer of Preferred Stock or
Conversion Shares by a

                                      -24-
<PAGE>

Purchaser to such Purchaser's affiliate (as defined in Section 11.3) and (c) a
transfer of Preferred Stock or Conversion Shares upon obtaining assurance
reasonably satisfactory to the Company that such transaction is exempt from the
registration requirements of, or is covered by an effective registration
statement under, the Act and applicable state securities or "Blue Sky" laws,
including, without limitation, receipt of an opinion to such effect in form and
of counsel reasonably satisfactory to the Company. The certificates representing
the Preferred Stock and any Conversion Shares shall bear a legend evidencing
such restriction on transfer substantially in the following form:

          "The securities represented by this certificate have been
          acquired for investment and have not been registered under
          the Securities Act of 1933 (the "Act") or the securities
                                           ---
          laws of any state and may not be sold or transferred
          except pursuant to a registration under the Act or an
          exemption therefrom."

          -------------------
terms shall have the following respective meanings:

          "Holder" means the Person who is the then record owner of Registrable
           ------
Securities which have not been sold to the public.

          "Initiating Holders" means any Purchaser or Purchasers or their
           ------------------
respective permitted assignees who in the aggregate are holders of at least
forty percent (40%) of the Conversion Shares then held by the Purchasers and
their respective permitted transferees (including shares of Common Stock issued
or issuable upon conversion of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred
Stock).

          "Registrable Securities" means (i) all of the Conversion Shares owned
           ----------------------
by the Purchasers, (ii) all other shares of Common Stock now owned or hereafter
acquired by any Purchaser; (iii) all shares of Common Stock issuable with
respect to securities of the Company convertible into or exercisable for shares
of Common Stock now owned or hereafter acquired by any Purchaser; and (iv) any
Common Stock issued in respect of the shares described in clauses (i) through
(iii) upon any stock split, stock dividend, recapitalization or other similar
event.

          The term "register", "registered" and "registration" refer to a
                    --------    ----------       ------------
registration effected by preparing and filing a registration statement in

any special audits incident to or required by any such registration.

          "Selling Expenses" means all underwriting discounts and selling
           ----------------
commissions applicable to the sale of Registrable Securities.

     7.2  Requested Registrations
          -----------------------

          (a)  Except as set forth in subsection (c) below, if, on any two (2)
occasions after the Closing, the Company shall receive from one or more
Initiating Holders a written request that the Company effect the registration of
Registrable Securities on Form S-1 or Form S-2 (or other successor form), the
Company will:

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

               (ii) as soon as practicable, use all commercially reasonable
     efforts to effect such registration as may be so requested and as would
     permit or facilitate the sale and distribution of such portion of such
     Registrable Securities as are specified in such request, together with such
     portion of the Registrable Securities of any Holder or Holders joining in
     such request as are specified in a written request by such Holder or
     Holders given to the Company within fifteen (15) days after receipt of such
     written notice from the Company.  If the underwriter managing the offering
     advises the Holders who have requested inclusion of their Registrable
     Securities in such registration that marketing considerations require a
     limitation on the number of shares offered, such limitation shall be
     imposed pro rata among such Holders who requested inclusion of Registrable
             ---------
     Securities in such registration according to the number of Registrable
     Securities each such Holder requested to be included in such registration.
     Neither the Company nor any other shareholder may include shares in a
     registration effected under this Section 7.2 without the consent of the
     Holders holding a majority of the Registrable Securities sought to be
     included in such registration if the inclusion of shares by the Company or
     the other shareholders would limit the number of Registrable Securities
     sought to be included by the Holders or reduce the offering price thereof.
     No registration initiated by Initiating Holders hereunder shall count as a
     registration under this Section 7.2 unless and until it shall have been
     declared effective or unless, in connection with such registration, at
     least seventy-six percent (76%) of the number of Registrable Securities for
     which registration has been requested are registered.  Notwithstanding the
     foregoing, a registration that is terminated or abandoned at the direction
     of a majority in interest of the selling Holders shall count as a
     registration under this Section 7.2 unless either: (i) the selling Holders
     shall pay or reimburse the Company for the Registration Expenses reasonably
     incurred in connection with such terminated or abandoned registration, or
     (ii) such registration is terminated or abandoned as a result of
     information concerning the business or financial condition of the Company
     which is made known to the selling Holders after the date on which such
     registration was requested.

                                      -26-
<PAGE>

          (b)  Selection of Underwriter.  The underwriter of any underwriting
               ------------------------
requested under this Section 7.2 shall be selected by the Holders holding a
majority of the Registrable Securities included therein; provided that such
underwriter must be reasonably acceptable to the Company.

          (c)  Special Conditions.  The Company shall not be obligated to effect
               ------------------
a registration of Registrable Securities pursuant to subsection (a) hereof:

               (i)   if the reasonably anticipated aggregate price to the public
     of the Registrable Securities to be included in such registration does not
     equal or exceed $5,000,000.00;

               (ii)  during the period starting with the date ninety (90) days
     prior to the Company's estimated date of filing of, and ending on a date
     ninety (90) days following the effective date of, a registration statement
     pertaining to an underwritten public offering of securities for the account
     of the Company, provided that the Company is actively employing in good
     faith all reasonable efforts to cause such registration statement to become
     effective and that the Company's estimate of the date of filing of such
     registration statement is made in good faith; or

               (iii) if the Company shall furnish to the Holders a certificate
     signed by the President of the Company stating that in the good faith
     judgment of the Board of Directors it would be seriously detrimental to the
     Company or its shareholders for a registration statement to be filed in the
     near future, in which case the Company's obligation under this Section 7.2
     to use its best efforts to file a registration statement shall be deferred
     for a period not to exceed three (3) months.

     7.3  "Piggy Back" Registration
           ------------------------

          (a)  If the Company shall determine to register any of its securities,
either for its own account or the account of a security holder or holders
exercising their registration rights, other than a registration relating solely
to employee benefit plans, or a registration on any registration form which does
not permit secondary sales or does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of Registrable Securities, the Company will:

               (i)  Promptly give to each Holder of Registrable Securities
     written notice thereof (which shall include the number of shares the
     Company or other security holder proposes to register and, if known, the
     name of the proposed underwriter); and

               (ii) Use its best efforts to include in such registration all the
     Registrable Securities specified in a written request or requests made by
     any Holder within fifteen (15) days after the date of delivery of the
     written notice from the Company described in clause (i) above.  If the
     underwriter advises the Company that marketing considerations require a
     limitation on the number of shares offered pursuant to any registration
     statement, then the Company may offer all of the securities it proposes to

                                      -27-
<PAGE>

     register for its own account or the maximum amount that the underwriter
     considers salable and such limitation on any remaining securities that may,
     in the opinion of the underwriter, be sold will be imposed pro rata among
                                                                --------
     all Holders who request to include shares in such registration statement
     according to the number of Registrable Securities each such Holder
     requested to be included in such registration statement.

          (b)  The Company shall select the underwriter for an offering made
pursuant to this Section 7.3; provided that such underwriter must be reasonably
acceptable to the Holders of a majority of the Registrable Securities being
registered in such offering.

     7.4  Expenses of Registration.  All Registration Expenses incurred in
          ------------------------
connection with any registration, qualification or compliance pursuant to
Section 7.2, 7.3 or 7.5 shall be paid by the Company.  All Selling Expenses
incurred in connection with any such registration, qualification or compliance
shall be borne by the holders of the securities registered, pro rata on the
basis of the number of their shares so registered.

     7.5  Registration on Form S-3.  The Company shall use its best efforts to
          ------------------------
qualify for registration on Form S-3 or any comparable or successor form; and to
that end the Company shall register (whether or not required by law to do so)
the Common Stock under the Securities Exchange Act of 1934 (the "Exchange Act")
                                                                 ------------
in accordance with the provisions of the Exchange Act either concurrently with
or immediately following the effective date of the first registration of any
securities of the Company on Form S-1 or any comparable or successor form.
After the Company has qualified for the use of Form S-3, in addition to the
rights contained in the foregoing provisions of this Article VII, one or more
Holders shall have the right to request registrations on Form S-3 (such requests
shall be in writing and shall state the number of shares of Registrable
Securities to be disposed of and the intended methods of disposition of such
shares by such Holder or Holders), provided that (a) the Company shall not be
obligated to effect more than five (5) registrations in the aggregate pursuant
to this Section 7.5 and not more than one (1) registration in any nine-month
period, (b) the Company shall not be obligated to effect any such registration
pursuant to this Section 7.5 more than once in any six month period, and (c) in
no event shall the Company be required to register shares with an aggregate
market value of less than $2,500,000.

     7.6  Registration Procedures.  In the case of each registration effected
          -----------------------
by the Company pursuant to this Article VII, the Company will keep each Holder
of Registrable Securities included in such registration advised in writing as to
the initiation of each registration and as to the completion thereof.  At its
expense, the Company will do the following, for the benefit of such Holders:

          (a)  Keep such registration effective for a period of one hundred
twenty days or until the Holder or Holders have completed the distribution
described in the registration statement relating thereto, whichever first
occurs, amend or supplement such registration statement and the prospectus
contained therein from time to time to the extent necessary to comply with the
Act and applicable state securities laws, and notify the Holders immediately of
the need for a supplement or amendment;

                                      -28-
<PAGE>

          (b)  Use its best efforts to register or qualify the Registrable
Securities covered by such registration under the applicable securities or "blue
sky" laws of such jurisdictions as the selling shareholders may reasonably
request; provided, that the Company shall not be obligated to qualify to do
business in any jurisdiction where it is not then so qualified or otherwise
required to be so qualified or to take any action which would subject it to the
service of process in suits other than those arising out of such registration;

          (c)  Furnish such number of prospectuses and other documents incident
hereto as a Holder from time to time may reasonably request;

          (d)  In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 7.2 hereof, the Company will
enter into any underwriting agreement reasonably necessary to effect the offer
and sale of Common Stock but not inconsistent with the provisions of this
Agreement and, provided such underwriting agreement contains customary
underwriting provisions and is entered into by the Holder and provided further
that, if the underwriter so requests, the underwriting agreement will contain
customary contribution provisions on the part of the Company;

          (e)  To the extent then permitted under applicable professional
guidelines and standards, obtain a comfort letter from the Company's independent
public accountants in customary form and covering such matters of the type
customarily covered by comfort letters and an opinion from the Company's counsel
in customary form and covering such matters of the type customarily covered in a
public issuance of securities, in each case addressed to the Holders, and
provide copies thereof to the Holders; and

          (f)  Permit the counsel to the selling shareholders whose expenses are
being paid pursuant to Section 7.4 hereof to inspect and copy such corporate
documents as such counsel may reasonably request.

     7.7  Indemnification.
          ---------------

          (a)  In connection with any registration under this Article VII, the
Company will, and hereby does, indemnify each Holder, each of its officers,
directors and partners, and each person controlling such Holder within the
meaning of the Act, with respect to which such registration, qualification or
compliance has been effected pursuant to this Article VII, and each underwriter,
if any, and each person who controls such underwriter within the meaning of the
Act, against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any prospectus, offering circular or
other document (including any related registration statement, notification or
the like) incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Act or the Exchange Act or
securities act of any state or any rule or regulation thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such registration, qualification or compliance, and will
reimburse each such

                                      -29-
<PAGE>

Holder, each of its officers, directors and partners, and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and defending any such claim, loss, damage,
liability or action, whether or not resulting in any liability, provided that
the Company will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense arises out of or is based on any
untrue statement (or alleged untrue statement) or omission (or alleged omission)
based upon written information furnished to the Company by such Holder or
underwriter and stated to be specifically for use therein.

          (b) In connection with a registration under this Article VII, each
Holder will, if Registrable Securities held by such Holder are included in the
securities as to which such registration, qualification or compliance is being
effected, indemnify the Company, each of its directors and officers and each
underwriter, if any, of the Company's securities covered by such a registration
statement, each person who controls the Company or such underwriter within the
meaning of the Act and the rules and regulations thereunder, each other such
Holder and each of their officers, directors and partners, and each person
controlling such Holder, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the Company and such Holder's directors, officers, partners, persons,
underwriters or control persons for any legal or any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, whether or not resulting in liability, in each case
to the extent, but only to the extent, that such untrue statement (or alleged
untrue statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Company by such Holder
and stated to be specifically for use therein; provided, however, that the
obligations of each Holder hereunder shall be limited to an amount equal to the
net proceeds received by such Holder upon sale of such Holder's securities.

          (c) Each party entitled to indemnification under this Section 7.7 (the
"Indemnified Party") shall give notice to the party required to provide
 -----------------
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
                      ------------------
has actual knowledge of any claim as to which indemnity may be sought, but the
failure of any Indemnifying Party to give such notice shall not relieve the
Indemnifying Party of its obligations under this Section 7.7 (except and to the
extent the Indemnifying Party has been prejudiced as a consequence thereof).
The Indemnifying Party will be entitled to participate in, and to the extent
that it may elect by written notice delivered to the Indemnified Party promptly
after receiving the aforesaid notice from such Indemnified Party, at its expense
to assume, the defense of any such claim or any litigation resulting therefrom,
with counsel reasonably satisfactory to such Indemnified Party, provided that
the Indemnified Party may participate in such defense at its expense,
notwithstanding the assumption of such defense by the Indemnifying Party, and
provided, further, that if the defendants in any such action shall include both
the Indemnified Party and the Indemnifying Party and the Indemnified Party shall
have reasonably concluded that there may be

                                      -30-
<PAGE>

legal defenses available to it and/or other Indemnified Parties which are
different from or additional to those available to the Indemnifying Party, the
Indemnified Party or Parties shall have the right to select separate counsel to
assert such legal defenses and to otherwise participate in the defense of such
action on behalf of such Indemnified Party or Parties and the fees and expenses
of such counsel shall be paid by the Indemnifying Party. No Indemnifying Party,
in the defense of any such claim or litigation, shall, except with the consent
of each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation. Each Indemnified Party shall
(i) furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with defense of such claim and litigation resulting
therefrom and (ii) shall reasonably assist the Indemnifying Party in any such
defense, provided that the Indemnified Party shall not be required to expend its
funds in connection with such assistance.

          (d) If the indemnification provided for in Sections 7.7(a) or 7.7(b)
is unavailable or insufficient to hold harmless an Indemnified Party under such
subsections in respect of any losses, claims, damages or liabilities or actions
in respect thereof referred to therein, then each Indemnifying Party shall in
lieu of indemnifying such Indemnified Party contribute to the amount paid or
payable by such Indemnified Party as a result of losses, claims, damages,
liabilities or actions in such proportion as appropriate to reflect the relative
fault of the Company, on the one hand, and the sellers of such Registrable
Securities, on the other, in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or actions as well as any
other relevant equitable considerations, including the failure to give any
notice under Section 7.7(c).  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact relates to information supplied by the Company on the one
hand, or the sellers of such Registrable Securities, on the other hand, and to
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.  The Company and the sellers
of Registrable Securities agree that it would not be just and equitable if
contributions pursuant to this paragraph were determined by pro rata allocation
                                                            --------
(even if all of the sellers of such Registrable Securities were treated as one
entity for such purpose) or by any other method of allocation which did not take
account of the equitable considerations referred to above in this subsection.
The amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages, liabilities or action in respect thereof, referred to above in
this paragraph, shall be deemed to include 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, the sellers of such Registrable Securities shall not be required to
contribute any amount in excess of the amount, if any, by which the net proceeds
received by such sellers for the Common Stock sold by each of them under such
registration statement exceeds the amount of any damages which they would have
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission.  No person guilty of fraudulent misrepresentations
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who is not guilty of such fraudulent
misrepresentation.

                                      -31-
<PAGE>

          (e) No Holder shall be required to participate in a registration
pursuant to which it would be required to execute an underwriting agreement in
connection with a registration effected under Section 7.2 or 7.3 which imposes
indemnification or contribution obligations on such Holder more onerous than
those imposed hereunder; provided, however, that the Company shall not be deemed
to breach the provisions of Section 7.2 or 7.3 if a Holder is not permitted to
participate in a registration on account of his refusal to execute an
underwriting agreement on the basis of this subsection (e).

          7.8 Information by Holder.  Each Holder of Registrable Securities
              ---------------------
included in any registration shall furnish to the Company such information
regarding such Holder and the distribution proposed by such Holder as the
Company may reasonably request in writing and as shall be reasonably required in
connection with any registration, qualification or compliance referred to in
this Article VII or otherwise required by applicable state or federal securities
laws.

          7.9 "Market Standoff Agreement".
               -------------------------

              (a) Each Holder, if requested by the Company and the managing
underwriter of an offering by the Company of Common Stock or other securities of
the Company pursuant to its initial registration, shall agree not to sell
publicly or otherwise transfer or dispose of any Registrable Securities or other
securities of the Company acquired prior to such initial public offering and
held by Holder for a specified period (not to exceed 180 days) following the
effective date of the first such registration; provided, however, that the
                                               --------  -------
foregoing restrictions shall not apply to securities purchased by any Holder in
the initial public offering, and provided, further, that the foregoing
                                 --------  -------
restrictions shall not apply to open market transactions by any Shareholder
which is an "investment company" as defined in the Investment Company Act of
1940, as amended.  Notwithstanding the foregoing, the Holders shall be under no
obligation to agree to such restrictions unless all directors, officers and key
management employees of the Company and all holders of more than five percent
(5%) of the outstanding capital stock of the Company agree to comparable
restrictions.  Notwithstanding Section 11.4 below, no amendment to this Section
7.9 shall be effective as to any Holder which is an Investment Company, without
the consent of such Holder.

              (b) The Company, if requested by the Holder and the managing
underwriter of an offering of Registrable Securities for the benefit of the
Holders, agrees (i) not to effect any public sale or distribution of its equity
securities, or any securities convertible into or exchangeable or exercisable
for such securities, during the seven (7) days prior to and during the ninety
(90) day period beginning on the effective date of any registration related to
an underwritten offering pursuant to which Registrable Securities are to be sold
(except as part of such underwritten registration or pursuant to registrations
on Form S-8 or Form S-4 or other registration relating to employee benefit plans
or the registration of securities relating to a transaction subject to Rule 145
under the Securities Act or on any form which does not permit secondary
resales), and (ii) to use best efforts to cause each officer, director and key
management employee of the Company and each holder of at least five percent (5%)
of the outstanding capital stock of the Company to agree to comparable
restrictions.

          7.10  Limitations on Registration Rights.  From and after the date of
                ----------------------------------
this Agreement, the Company shall not enter into any agreement with any holder
or prospective holder of any securities of the Company giving such holder or
prospective holder (a) the right to require the Company, upon any registration
of any of its securities, to include, among the securities which the Company is
then registering, securities owned by such holder, unless under the terms of
such agreement, such holder or prospective holder may include such securities in
any such registration only to the extent that the inclusion of its securities
will not limit the number of Registrable Securities sought to be included by the
Holders of Registrable Securities or reduce the offering price thereof; or (b)
the right to require the Company to initiate any registration of any securities
of the Company.

          7.11  Exception to Registration.  The Company shall not be required to
                -------------------------
effect a registration under this Article VII if (i) in the written opinion of
counsel for the Company, which counsel and the opinion so rendered shall be
reasonably acceptable to the Holders of Registrable Securities, such Holders may
sell without registration under the Act all Registrable Securities for which
they requested registration under the provisions of the Act and in the manner
and in the quantity in which the Registrable Securities were proposed to be
sold, or (ii) the Company shall have obtained from the Commission a "no action"
letter to that effect; provided that this Section 7.11 shall not apply to sales
made under Rule 144(k) or any successor rule promulgated by the Commission until
after the effective date of the Company's initial registration of shares under
the Act.  Notwithstanding the foregoing, in no event shall the provisions of
this Section 7.11 be construed to preclude a Holder of Registrable Securities
from exercising rights under Section 7.3 for a period of three years after the
effective date of the Company's initial registration of shares under the Act.

          7.12  Rule 144 Reporting.  With a view to making available the
                ------------------
benefits of certain rules and regulations of the Commission which may permit the
sale of restricted securities (as that term is used in Rule 144 under the Act)
to the public without registration, the Company agrees to:

                (a) make and keep public information available as those terms
are understood and defined in Rule 144 under the Act, at all times from and
after ninety (90) days following the effective date of the first registration
under the Act filed by the Company for an offering of its securities to the
general public;

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

                (c) so long as a Purchaser owns any restricted securities,
furnish to the Purchaser forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of Rule 144 (at any
time from and after ninety days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Act and Exchange Act (at any time after it has
become subject to such reporting requirements), a copy of the most recent annual
or quarterly

                                      -33-
<PAGE>

report of the Company, and such other reports and documents so filed as a
Purchaser may reasonably request in availing itself of any rule or regulation of
the Commission allowing a Purchaser to sell any such securities without
registration.

          7.13  Listing Application.  If shares of any class of stock of the
                -------------------
Company shall be listed on a national securities exchange, the Company shall, at
its expense, include in its listing application all of the shares of the listed
class then owned by any Purchaser.

          7.14  Damages.  The Company recognizes and agrees that the Holder of
                -------
Registrable Shares shall not have an adequate remedy if the Company fails to
comply with the provisions of this Article VII, and that damages will not be
readily ascertainable, and the Company expressly agrees that in the event of
such failure any Holder of Registrable Shares shall be entitled to specific
performance of the Company's obligations hereunder and that the Company will not
oppose an application seeking such specific performance.

          7.15  Termination of Registration Rights.  All of the registration
                ----------------------------------
rights set forth in this Article 7 shall terminate: (i) as to all Holders, on
the fourth anniversary of the date on which the registration statement in
respect of the Company's initial public offering became effective, and (ii) as
to any individual Holder, the date on which such Holder becomes first eligible
to sell all of his, her or its Registrable Securities under Rule 144 within any
three (3) month period or otherwise pursuant to Rule 144(k).

                ---------------------------
covenants and agreements made herein or in any certificates or documents
executed in connection herewith shall survive the execution and delivery hereof

                -------------------
covenants, agreements, representations, warranties and undertakings contained in
this Agreement shall be binding on and shall inure to the benefit of the

          11.4  Amendments and Waivers.  Amendments or additions to this

Agreement may be made, agreements with any decision of the Company may be made,
and compliance with any term, covenant, agreement, condition or provision set
forth herein may be omitted or waived (either generally or in a particular
instance and either retroactively or prospectively) upon the written consent of
the Company and the holders of fifty-one percent (51 %) of the issued and
issuable Conversion Shares (calculated as if all outstanding shares of all
series of Preferred Stock had been converted to Common Stock).  Prompt notice of
any such amendment or waiver shall be given to any Person who did not consent
thereto.  This Agreement (including the Schedules and Exhibits annexed hereto,
                                                      --------
which are an integral part of this Agreement) and the Related Agreements
constitute the full and complete agreement of the parties with respect to the
subject matter hereof.

          Notwithstanding anything in this Agreement to the contrary, no waiver,
omission, amendment or addition to this Agreement may be made which (i) modifies
this Section 11.4 or (ii) would affect the holders of each series of Preferred
Stock in a disproportionate manner (other than any disproportionate results
which are due to the rights, preferences, privileges or limitations set forth in
the Company's charter, as amended to date).  For purposes hereof, the term
"disproportionate manner" shall refer to any event which would impair the rights
of one holder while not impairing similar rights held by another holder of the

or advantage, or impose any detriment or disadvantage, for any series of the
Preferred Stock without also extending a similar benefit or imposing a similar
detriment, on a proportionate percentage of equity basis, to the other series of
Preferred Stock.  By way of illustration, the Company shall not change the
reporting requirements for any series of the Preferred Stock, or increase the
liquidation preference or redemption amount for any series of Preferred Stock
without also changing on a similar basis the reporting requirements, or
increasing by a similar proportionate percentage, the liquidation preference or
redemption amount for the other series of Preferred Stock.  All numerical
adjustments shall be made on a proportionate percentage (based on any
Purchaser's relative equity interest in the Company) and not on an absolute
numerical basis.

additional shares of any class or series of preferred stock of the Company may,
at the discretion of the Board of Directors, become parties to this Agreement
(as amended from time to time) by executing a counterpart signature page to this
Agreement.  By execution of such counterpart signature page, this Agreement
shall be automatically amended and such person or entity shall be deemed to be a
"Purchaser" for all purposes of this Agreement, and as such shall be entitled to
the rights and benefits, and be bound by the obligations, of this Agreement.

indemnify may be unenforceable for any reason, the Company shall make the
maximum contribution to the payment and satisfaction of each of the indemnified
liabilities which shall be permissible under applicable law.

Purchasers would be irreparably and immediately harmed and could not be made

any rights and remedies otherwise available to the Purchasers, the Purchasers
shall each be entitled (a) to equitable relief by way of injunction in the event
of the Company's Default or threatened Default, (b) to compel specific
performance, and (c) such other equitable relief as may be necessary or
appropriate to restrain such Default or threatened Default, in each case without

of litigation relating to the foregoing, if a court of competent jurisdiction
determines that a Default or threatened Default has occurred, the Company shall
be liable and shall pay the reasonable legal fees incurred by the Purchasers in
connection with such litigation, including any appeal therefrom.  No failure or
delay by the Purchasers in exercising any right, power or privilege hereunder
shall operate as a waiver thereof, or shall any single or partial exercise
thereof preclude any other or further exercise hereunder.

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

            (a) The rights granted to a Purchaser under Sections 3.1, 3.5, 3.10,
3.11, Article V and Article VII hereof may be transferred by such Purchaser to
another Purchaser, to any affiliate of a Purchaser, to any affiliate of the
Company or to any person or entity acquiring at least 400,000 Conversion Shares
(as appropriately adjusted for a stock split, stock dividend, reorganization,
reclassification or other similar event with respect to the Preferred Stock,
including any transferee of Series E Preferred Stock convertible into such
number of Conversion Shares or Registrable Securities); provided, however, that

under

                                      -41-
<PAGE>

Section 3.1, Section 3.5 or 3.10, 3.11, also Section 11.13, to the same extent

instrument in accordance with subparagraph (b) above and containing the

corporation or limited liability company, it shall be a condition to such
transfer that such partnership, corporation or limited liability company
designates one person as agent for receipt of all notices on behalf of such
partners, stockholders or members, as the case may be.  In the event of such
transfer, such partner, stockholder or member shall be deemed a Purchaser for
purposes of this Section 11.12 and may again transfer such rights to any other
person or entity which acquires such shares of Preferred Stock or Registrable
Securities from such partner, stockholder or member, in accordance with, and
subject to, the provisions of subparagraphs (a), (b) and (c) above.

          (e) Minimum Transfers.  Notwithstanding anything to the contrary

reorganization, reclassification or other similar event with respect to the
Preferred Stock) to any transferee; provided, however, that a Purchaser may

transfer any number of shares to another Purchaser, to an affiliate of the
Company, to a stockholder of the Company or, if such Purchaser is a partnership,
corporation or limited liability company, to a partner, stockholder or member
thereof, and provided, further, that any Purchaser holding 400,000 or fewer
             -----------------
Registrable Securities may only transfer such Registrable Securities to another
Purchaser, to any affiliate of the Company, to any stockholder of the Company or
to no more than two other transferees.  The foregoing restrictions shall not
apply to transfers of Registrable Securities once the Company becomes subject to
the reporting requirements of Section 12 of the Exchange Act.

                  presentment, demand of payment, filing of claims with a court

                  right to require a proceeding first against the Company,
                  protest, notice and all demands whatsoever.

                           (d) This Guarantee shall not be discharged except by

                  and the Indenture.

                  paid by either to the Trustee or such Holder, this Guarantee,
                  to the extent theretofore discharged, shall be reinstated in
                  full force and effect.

                           (f) The Guaranteeing Subsidiary shall not be entitled
                  to any right of subrogation in relation to the Holders in
                  respect of any obligations guaranteed hereby until payment in
                  full of all obligations guaranteed hereby.

                           (g) As between the Guarantors, on the one hand, and
                  the Holders and the Trustee, on the other hand, (x) the
                  maturity of the obligations guaranteed hereby may be
                  accelerated as provided in Article 6 of the Indenture for the
                  purposes of this Guarantee, notwithstanding any stay,
                  injunction or other prohibition preventing such acceleration
                  in respect of the obligations guaranteed hereby, and (y) in
                  the event of any declaration of acceleration of such
                  obligations as provided in Article 6 of the Indenture, such
                  obligations (whether or not due and payable) shall forthwith
                  become due and payable by the Guarantors for the purpose of
                  this Guarantee.

                  contribution from any non-paying Guarantor so long as the
                  exercise of such right does not impair the rights of the
                  Holders under the Guarantee.

                           (i) Pursuant to Section 10.02 of the Indenture, after
                  giving effect to any maximum amount and any other contingent
                  and fixed liabilities that are relevant under any applicable
                  Bankruptcy or fraudulent conveyance laws, and after giving
                  effect to any collections from, rights to receive contribution
                  from or payments made by or on behalf of any other Guarantor
                  in respect of the obligations of such other Guarantor under
                  Article 10 of the Indenture shall result in the obligations of
                  such Guarantor under its Guarantee not constituting a
                  fraudulent transfer or conveyance.

                  3.       Execution and Delivery. The Guaranteeing Subsidiary
                           ----------------------
agrees that the Guarantee shall remain in full force and effect notwithstanding
any failure to endorse on each Note a notation of such Guarantee.

                  4.       Guaranteeing Subsidiary May Consolidate, Etc. on

Certain Terms.
-------------
                           (a)   The Guaranteeing Subsidiary may not consolidate
                  with or merge with or into (whether or not such Guarantor is
                  the surviving Person) another corporation, Person or entity
                  whether or not affiliated with such Guarantor unless:

                           (i)   subject to Section 10.05 of the Indenture, the
                                 Person formed by or surviving any such
                                 consolidation or merger (if other than a
                                 Guarantor or the Company) unconditionally
                                 assumes all the obligations of such Guarantor,
                                 pursuant to a supplemental indenture in form
                                 and substance reasonably satisfactory to the
                                 Trustee, under the Notes, the Indenture and the
                                 Guarantee on the terms set forth herein or
                                 therein; and

                           (ii)  immediately after giving effect to such
                                 transaction, no Default or Event of Default
                                 exists.

                           (b)   In case of any such consolidation, merger, sale
                  or conveyance and upon the assumption by the successor
                  corporation, by supplemental indenture, executed and delivered
                  to the Trustee and

<PAGE>

                  satisfactory in form to the Trustee, of the Guarantee endorsed

                  the covenants and conditions of the Indenture to be performed
                  by the Guarantor, such successor corporation shall succeed to
                  and be substituted for the Guarantor with the same effect as
                  if it had been named herein as a Guarantor. Such successor
                  corporation thereupon may cause to be signed any or all of the
                  Guarantees to be endorsed upon all of the Notes issuable
                  hereunder which theretofore shall not have been signed by the
                  Company and delivered to the Trustee. All the Guarantees so
                  issued shall in all respects have the same legal rank and
                  benefit under the Indenture as the Guarantees theretofore and
                  thereafter issued in accordance with the terms of the
                  Indenture as though all of such Guarantees had been issued at
                  the date of the execution hereof.

                        (c) Except as set forth in Articles 4 and 5 of the
                  Indenture, and notwithstanding clauses (a) and (b) above,
                  nothing contained in the Indenture or in any of the Notes
                  shall prevent any consolidation or merger of a Guarantor with
                  or into the Company or another Guarantor, or shall prevent any
                  sale or conveyance of the property of a Guarantor as an
                  entirety or substantially as an entirety to the Company or
                  another Guarantor.

                  5.    Releases.
                        --------

                        (a) In the event of a sale or other disposition of
                  all of the assets of any Guarantor, by way of merger,
                  consolidation or otherwise, or a sale or other disposition of
                  all of the capital stock of any Guarantor, then such Guarantor
                  (in the event of a sale or other disposition, by way of
                  merger, consolidation or otherwise, of all of the capital
                  stock of such Guarantor) or the corporation acquiring the
                  property (in the event of a sale or other disposition of all
                  or substantially all of the assets of such Guarantor) will be
                  released and relieved of any obligations under its Guarantee;
                  provided that the Net Proceeds of such sale or other
                  disposition are applied in accordance with the applicable
                  provisions of the Indenture, including without limitation
                  Section 4.10 of the Indenture. Upon delivery by the Company to
                  the Trustee of an Officers' Certificate and an Opinion of
                  Counsel to the effect that such sale or other disposition was
                  made by the Company in accordance with the provisions of the
                  Indenture, including without limitation Section 4.10 of the
                  Indenture, the Trustee shall execute any documents reasonably
                  required in order to

                                       5
<PAGE>

                  evidence the release of any Guarantor from its obligations
                  under its Guarantee.

                        (b) Any Guarantor not released from its obligations
                  under its Guarantee shall remain liable for the full amount of
                  principal of and interest on the Notes and for the other
                  obligations of any Guarantor under the Indenture as provided
                  in Article 10 of the Indenture.

                  6.    No Recourse Against Others. No past, present or future
                        --------------------------
director, officer, employee, incorporator, stockholder or agent of the
Guaranteeing Subsidiary, as such, shall have any liability for any obligations
of the Company, the Guaranteeing Subsidiary or under the Notes, any Guarantees,
the Indenture or this Supplemental Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder of
the Notes by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for issuance of the Notes. Such waiver
may not be effective to waive liabilities under the federal securities laws and
it is the view of the Commission that such a waiver is against public policy.

                  8.    NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF
                        ----------------------
NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

                  9.    Counterparts. The parties may sign any number of copies
                        ------------
of this Supplemental Indenture. Each signed copy shall be an original, but all
of them together represent the same agreement.

                  10.   Effect of Headings. The Section headings herein are for
                        ------------------
convenience only and shall not affect the construction hereof.

                  11.   The Trustee. The Trustee shall not be responsible in any
                        -----------
manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Subsidiary, MFB, Great
American, Pretzelmaker, and the Company.
