conversion of Series C Preferred (in each case, the "INITIATING HOLDERS"), then
the Company shall, within thirty (30) days of the receipt thereof, give written
notice of such request to all Holders, and subject to the limitations of this
Section 2.2, use its best efforts to effect, as soon as practicable, the
registration under the Securities Act of all Registrable Securities that the
Holders request to be registered.

                  (b) If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 2.2 or any request pursuant to Section 2.4 and the Company shall
include such information in the written notice referred to in Section 2.2(a) or
Section 2.4(a), as applicable. In such event, the right of any Holder to include
its Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by a majority in interest of the
Initiating Holders (which underwriter or underwriters shall be reasonably
acceptable to the Company). Notwithstanding any other provision of this Section
2.2 or Section 2.4, if the underwriter advises the Company that marketing
factors require a limitation of the number of securities to be underwritten
(including Registrable Securities) then the Company shall so advise all Holders
of Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares that may be included in the underwriting shall be
allocated to the Holders of such Registrable Securities on a pro rata basis
based on the number of Registrable Securities held by all such Holders
(including the Initiating Holders). Any Registrable Securities excluded or
withdrawn from such underwriting shall be withdrawn from the registration.

                  (c) The Company shall not be required to effect a registration
pursuant to this Section 2.2:

                           (i) prior to February 26, 2002; unless the Company's
Initial Offering occurs before February 26, 2002, in which case the Company
shall be required to effect registrations pursuant to this Section 2.2 beginning
the day following the date one hundred eighty (180) days after the Company's
Initial Offering.



                                       6.
<PAGE>   11

                           (ii) after the Company has filed three (3)
registrations pursuant to this Section 2.2, and such registrations have been
declared or ordered effective and either: (A) such registration has been
declared or ordered effective; or (B) the request for such registration has been
subsequently withdrawn by the Initiating Holders, unless the withdrawal is based
upon material adverse information concerning the Company of which the Initiating
Holders were not aware at the time of such request; provided, however, that if
the Initiating Holders shall pay all expenses of such withdrawn registration,
then such withdrawn registration shall not be considered for purposes of
determining whether the Company has satisfied its obligations under this Section
2.2(c)(ii).

                           (iii) during the period starting with the date of
filing of, and ending on the date one hundred eighty (180) days following the
effective date of the registration statement pertaining to the Company's Initial
Offering; provided that the Company makes reasonable good faith efforts to cause
such registration statement to become effective;

                           (iv) if within thirty (30) days of receipt of a
written request from Initiating Holders pursuant to Section 2.2(a), the Company
gives notice to the Holders of the Company's intention to make a public offering
within ninety (90) days;

                           (v) if the Company shall furnish to Holders
requesting a registration statement pursuant to this Section 2.2, a certificate
signed by the Chairman of the Board stating that in the good faith judgment of
the Board of Directors of the Company, it would be seriously detrimental to the
Company and its stockholders for such registration statement to be effected at
such time, in which event the Company shall have the right to defer such filing
for a period of not more than ninety (90) days after receipt of the request of
the Initiating Holders; provided that such right to delay a request shall be
exercised by the Company not more than once in any twelve (12) month period; or

                           (vi) without prejudice to the rights of the Holders
under Section 2.4 hereof, if the Initiating Holders propose to dispose of shares
of Registrable Securities that may be immediately registered on Form S-3
pursuant to a request made pursuant to Section 2.4 below.

         2.3 PIGGYBACK REGISTRATIONS. The Company shall notify all Holders of
Registrable Securities in writing at least thirty (30) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to employee benefit
plans or with respect to corporate reorganizations or other transactions under
Rule 145 of the Securities Act) and will afford each such Holder an opportunity
to include in such registration statement all or part of such Registrable
Securities held by such Holder. Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it
shall, within thirty (30) days after the above-described notice from the
Company, so notify the Company in writing. Such notice shall state the intended
method of disposition of the Registrable Securities by such Holder. If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or



                                       7.
<PAGE>   12

registration statements as may be filed by the Company with respect to offerings
of its securities, all upon the terms and conditions set forth herein.

                  (a) UNDERWRITING. If the registration statement under which
the Company gives notice under this Section 2.3 is for an underwritten offering,
the Company shall so advise the Holders of Registrable Securities. In such
event, the right of any such Holder to be included in a registration pursuant to
this Section 2.3 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their Registrable Securities through such underwriting shall enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of the Agreement, if the underwriter determines in good faith that
marketing factors require a limitation of the number of shares to be
underwritten, the number of shares that may be included in the underwriting
shall be allocated, first, to the Company; second, to the Holders on a pro rata
basis based on the total number of Registrable Securities held by the Holders;
and third, to any stockholder of the Company (other than a Holder) on a pro rata
basis. No such reduction shall (i) reduce the securities being offered by the
Company for its own account to be included in the registration and underwriting,
or (ii) reduce the amount of securities of the selling Holders included in the
registration below twenty-five percent (25%) of the total amount of securities
included in such registration, unless such offering is the Initial Offering and
such registration does not include shares of any other selling stockholders, in
which event any or all of the Registrable Securities of the Holders may be
excluded in accordance with the immediately preceding sentence. In no event will
shares of any other selling stockholder be included in such registration which
would reduce the number of shares which may be included by Holders without the
written consent of Holders of not less that sixty-six and two-thirds (66 2/3%)
of the Registrable Securities proposed to be sold in the offering. If any Holder
disapproves of the terms of any such underwriting, such Holder may elect to
withdraw therefrom by written notice to the Company and the underwriter,
delivered at least ten (10) business days prior to the effective date of the
registration statement. Any Registrable Securities excluded or withdrawn from
such underwriting shall be excluded and withdrawn from the registration. For any
Holder which is a partnership, limited liability corporation or corporation, the
partners, members, retired partners, retired members, and stockholders of such
Holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing person shall,
unless such persons also directly own Registrable Securities for their own
account, be deemed to be a single "HOLDER", and any pro rata reduction with
respect to such "Holder" shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in
such "Holder," as defined in this sentence.

                  (b) RIGHT TO TERMINATE REGISTRATION. The Company shall have
the right to terminate or withdraw any registration initiated by it under this
Section 2.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. The Registration
Expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 2.5 hereof.

         2.4 FORM S-3 REGISTRATION. In case the Company shall receive from any
Holder or Holders of Registrable Securities a written request or requests that
the Company effect a



                                       8.
<PAGE>   13

registration on Form S-3 (or any successor to Form S-3) or any similar
short-form registration statement and any related qualification or compliance
with respect to all or a part of the Registrable Securities owned by such Holder
or Holders, the Company will:

                  (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders of Registrable
Securities; and

                  (b) as soon as practicable, effect such registration and all
such qualifications and compliance as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within
fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.4:

                           (i) if Form S-3 (or any successor or similar form) is
not available for such offering by the Holders, or

                           (ii) if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public of less than five hundred thousand dollars
($500,000), or

                           (iii) if within thirty (30) days of receipt of a
written request from Initiating Holders pursuant to Section 2.2(a), the Company
gives notice to the Holders of the Company's intention to make a public offering
within ninety (90) days;

                           (iv) if the Company shall furnish to the Holders a
certificate signed by the Chairman of the Board of Directors of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such Form S-3 registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement for a period of not more than ninety (90) days after receipt of the
request of the Holder or Holders under this Section 2.4; provided, that such
right to delay a request shall be exercised by the Company not more than once in
any twelve (12) month period, or

                           (v) in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or
compliance.

                  (c) Subject to the foregoing, the Company shall file a Form
S-3 registration statement covering the Registrable Securities and other
securities so requested to be registered as soon as practicable after receipt of
the request or requests of the Holders. Registrations effected pursuant to this
Section 2.4 shall not be counted as demands for registration or registrations
effected pursuant to Sections 2.2 or 2.3, respectively.



                                       9.

         2.5 EXPENSES OF REGISTRATION. Except as specifically provided herein,
all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2 or any registration under
Section 2.3 or Section 2.4 herein shall be borne by the Company. All Selling
Expenses incurred in connection with any registrations hereunder, shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to
pay for expenses of any registration proceeding begun pursuant to Section 2.2 or
2.4, the request of which has been subsequently withdrawn by the Initiating
Holders unless (a) the withdrawal is based upon material adverse information
concerning the Company of which the Initiating Holders were not aware at the
time of such request or (b) the Holders of a majority of Registrable Securities
agree to forfeit their right to one requested registration pursuant to Section
2.2, in which event such right shall be forfeited by all Holders). If the
Holders are required to pay the Registration Expenses, such expenses shall be
borne by the holders of securities (including Registrable Securities) requesting
such registration in proportion to the number of shares for which registration
was requested. If the Company is required to pay the Registration Expenses of a
withdrawn offering pursuant to clause (a) above, then the Holders shall not
forfeit their rights pursuant to Section 2.2 to a demand registration.

         2.6 OBLIGATIONS OF THE COMPANY. Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use all reasonable efforts to
cause such registration statement to become effective, and, upon the request of
the Holders of a majority of the Registrable Securities registered thereunder,
keep such registration statement effective for up to ninety (90) days or, if
earlier, until the Holder or Holders have completed the distribution related
thereto. The Company shall not be required to file, cause to become effective or
maintain the effectiveness of any registration statement that contemplates a
distribution of securities on a delayed or continuous basis pursuant to Rule 415
under the Securities Act.

                  (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement for the period set forth in
paragraph (a) above.

                  (c) Furnish to the Holders such number of copies of a
prospectus, including a preliminary prospectus, and such amendments and
supplements thereto, in conformity with the requirements of the Securities Act,
and such other documents as they may reasonably request in order to facilitate
the disposition of Registrable Securities owned by them.

                  (d) Use its reasonable best efforts to register and qualify
the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders; provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions.



                                      10.
<PAGE>   15

                  (e) Use its reasonable best efforts to cause all securities
covered by such registration statement to be registered with or approved by such
other governmental authorities in the United States as may be necessary by
virtue of the business and operations of the Company to enable the sellers to
consummate the disposition thereof;

                  (f) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter(s) of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                  (g) Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing and, at the request of any Holder of securities participating in the
registration, promptly prepare a supplement or an amendment of such prospectus
as may be necessary so that, as thereafter delivered to the purchasers of such
securities, such prospectus shall not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in light of the circumstances
under which they were made.

                  (h) Use its best efforts to furnish, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such
securities are being sold through underwriters, (i) an opinion, dated as of such
date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and (ii)
a letter dated as of such date, from the independent certified public
accountants of the Company, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten
public offering addressed to the underwriters.

                  (i) Use its reasonable best efforts to cause all securities
covered by such registration statement to be listed on a national securities
exchange in the united States or on the National Association of Securities
Dealers, Inc. National Market System (if such securities are not already so
listed), and on each other securities exchange on which similar securities
issued by the Company are then listed, if the listing of such securities covered
by the such registration statement is then permitted under the rules of such
exchange.

         2.7 TERMINATION OF REGISTRATION RIGHTS. A Holder's registration rights
shall expire if (a) the Company has completed its Initial Offering and is
subject to the provisions of the Exchange Act, (b) all Registrable Securities
held by and issuable to such Holder (and its affiliates, partners, former
partners, members and former members) may be sold under Rule 144 during any
ninety (90) day period, and (c) such Holder holds less than one-half (1/2)
percent of the issued and outstanding shares of the Company, on an as if
converted basis.

         2.8 FURNISHING INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Section 2.2, 2.3 or
2.4 that the selling Holders shall



                                      11.
<PAGE>   16

furnish to the Company such information regarding themselves, the Registrable
Securities held by them and the intended method of disposition of such
securities as shall be required to effect the registration of their Registrable
Securities.

         2.9 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under Sections 2.2, 2.3 or 2.4:

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, the partners, officers, employees, agents,
advisors and directors of each Holder, any underwriter (as defined in the
Securities Act) for such Holder and each person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"VIOLATION") by the Company: (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, or in any application or other document or
communication executed by or on behalf of the Company or based upon written
information by or on behalf of the Company filed in any jurisdiction in order to
qualify any securities covered by such registration statement under the "blue
sky" or securities laws thereof, (ii) 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 (iii) any violation or alleged violation
by the Company of the Securities Act, the Exchange Act, any state securities law
or any rule or regulation promulgated under the Securities Act, the Exchange Act
or any state securities law in connection with the offering covered by such
registration statement; and the Company will pay as incurred to each such
Holder, partner, officer, director, underwriter, employee, agent, advisor or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided however, that the indemnity agreement contained in
this Section 2.9(a) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Company, which consent shall not be unreasonably withheld,
nor shall the Company be liable in any such case for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon
a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
such Holder, partner, officer, director, employee, agent, advisor, underwriter
or controlling person of such Holder.

                  (b) To the extent permitted by law, each Holder, severally and
not jointly, will, if Registrable Securities held by such Holder are included in
the securities as to which such registration qualifications or compliance is
being effected, indemnify and hold harmless the Company, each of its directors,
employees, agents, advisors, officers and each person, if any, who controls the
Company within the meaning of the Securities Act, any underwriter and any other
Holder selling securities under such registration statement or any of such other
Holder's partners, directors, officers, employees, agents, advisors or any
person who controls such Holder, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, employee, agent, advisor, controlling person, underwriter or other such



                                      12.
<PAGE>   17

Holder, or partner, director, officer, employee, agent, advisor or controlling
person of such other Holder may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereto) arise out of or are based
upon any Violation, in each case to the extent (and only to the extent) that
such Violation occurs in reliance upon and in conformity with written
information furnished by such Holder under an instrument duly executed by such
Holder and stated to be specifically for use in connection with such
registration; and each such Holder will pay as incurred any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, employee, agent, advisor, underwriter or other Holder, or
partner, officer, director, employee, agent, advisor or controlling person of
such other Holder in connection with investigating or defending any such loss,
claim, damage, liability or action if it is judicially determined that there was
such a Violation; provided, however, that the indemnity agreement contained in
this Section 2.9(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of such Holder, which consent shall not be unreasonably withheld;
provided further, that in no event shall any indemnity under this Section 2.9
exceed the net proceeds from the offering received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
Section 2.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.9, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.9, but the omission so to deliver
written notice to the indemnifying party will not relieve such indemnifying
party of any liability that it may have to any indemnified party otherwise than
under this Section 2.9.

                  (d) If the indemnification provided for in this Section 2.9 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any losses, claims, damages or liabilities referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,



                                      13.
<PAGE>   18

knowledge, access to information and opportunity to correct or prevent such
statement or omission; provided, that in no event shall any contribution by a
Holder hereunder exceed the net proceeds from the offering received by such
Holder.

                  (e) The obligations of the Company and Holders under this
Section 2.9 shall survive completion of any offering of Registrable Securities
in a registration statement and the termination of this agreement. 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.

         2.10 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company
to register Registrable Securities pursuant to this Section 2 may be assigned by
a Holder to a transferee or assignee of Registrable Securities which (a) is a
subsidiary, affiliate, parent, general partner, limited partner, retired
partner, member or retired member of a Holder, (b) is a Holder's family member
or trust for the benefit of an individual Holder, (c) acquires at least two
hundred fifty thousand (250,000) shares of Registrable Securities (as adjusted
for stock splits and combinations), (d) acquires all of such Holder's shares of
Registrable Securities, or (e) is a Permitted Transferee; provided, however, (i)
the transferor shall, within ten (10) days after such transfer, furnish to the
Company written notice of the name and address of such transferee or assignee
and the securities with respect to which such registration rights are being
assigned and (ii) such transferee shall agree to be subject to all restrictions
set forth in this Agreement.

         2.11 AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Section 2
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least sixty percent (60%)
of the Registrable Securities then outstanding; provided that any amendment or
waiver of Section 2.2 may be effected with the written consent of the holders of
at least sixty percent (60%) of the Registrable Securities then outstanding,
excluding shares held by the Management Holders. Any amendment or waiver
effected in accordance with this Section 2.11 shall be binding upon each Holder
and the Company. By acceptance of any benefits under this Section 2, Holders of
Registrable Securities hereby agree to be bound by the provisions hereunder.

         2.12 LIMITATION ON SUBSEQUENT REGISTRATION RIGHTS. After the date of
this Agreement, the Company shall not, without the prior written consent of the
Holders of at least a majority of the Registrable Securities then outstanding,
enter into any agreement with any holder or prospective holder of any securities
of the Company that would grant such holder registration rights senior to those
granted to the Holders hereunder.

         2.13 "MARKET STAND-OFF" AGREEMENT; AGREEMENT TO FURNISH INFORMATION.
Each Holder hereby agrees that such Holder shall not sell, transfer, make any
short sale of, grant any option for the purchase of, or enter into any hedging
or similar transaction with the same economic effect as a sale, or otherwise
reduce its risk of ownership or investment in, any Common Stock (or other
securities) of the Company held by such Holder (other than those included in the
registration) for a period (if any) specified by the representative of the



                                      14.
<PAGE>   19

underwriters of Common Stock (or other securities) of the Company with respect
to each such transaction not to exceed one hundred eighty (180) days following
the effective date of a registration statement of the Company filed under the
Securities Act; provided that all officers and directors of the Company and
holders of at least one percent (1%) of the Company's voting securities enter
into similar agreements, and such agreements have not been waived with respect
to any such officer, director or holder of at least 1% of the Company. The
Company may impose stop-transfer instructions with respect to the shares of
Common Stock (or other securities) subject to the foregoing restriction until
the end of said one hundred eighty (180) day period.

         Each Holder agrees to execute and deliver such other agreements as may
be reasonably requested by the Company or the underwriter which are consistent
with the foregoing or which are necessary to give further effect thereto. In
addition, if requested by the Company or the representative of the underwriters
of Common Stock (or other securities) of the Company, each Holder shall provide,
within ten (10) days of such request, such information as may be required by the
Company or such representative in connection with the completion of any public
offering of the Company's securities pursuant to a registration statement filed
under the Securities Act. The obligations described in this Section 2.13 shall
not apply to a registration relating solely to employee benefit plans on Form
S-1 or Form S-8 or similar forms that may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4 or
similar forms that may be promulgated in the future.

         2.14 RULE 144 REPORTING. With a view to making available to the Holders
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its best efforts to:

                  (a) Make and keep public information available, as those terms
are understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times after the effective date of
the first registration filed by the Company for an offering of its securities to
the general public;

                  (b) File with the SEC, in a timely manner, all reports and
other documents required of the Company under the Exchange Act; and

                  (c) So long as a Holder owns any Registrable Securities,
furnish to such Holder forthwith upon request: a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144 of
the Securities Act, and of the Exchange Act (at any time after it has become
subject to such reporting requirements); a copy of the most recent annual or
quarterly report of the Company; and such other reports and documents as a
Holder may reasonably request in availing itself of any rule or regulation of
the SEC allowing it to sell any such securities without registration.

reasonably requested; provided, however, that the Company shall not be obligated
under this Section 3.2 with respect to a competitor of the Company or with
respect to information which the Board of Directors determines in good faith
would destroy the attorney-client privilege.

         3.3 CONFIDENTIALITY OF RECORDS. Each Investor agrees to use, and to use
its best efforts to insure that its authorized representatives use, the same
degree of care as such Investor uses to protect its own confidential information

not in the public domain), except that such Investor may disclose such
proprietary or confidential information to any partner, subsidiary, affiliate or

connection therewith, the Company shall give each such representative copies of
all notices, minutes, consents and other materials, financial or otherwise,
which the Company provides to its Board of Directors; provided, however, that

SECTION 4. PREEMPTIVE RIGHTS

         4.1 SUBSEQUENT OFFERINGS. Each Major Investor shall have a preemptive
right to purchase its pro rata share of all Equity Securities, as defined below,
that the Company may, from time to time, propose to sell and issue after the
date of this Agreement, other than the Equity Securities excluded by Section 4.6
hereof. Each Investor's pro rata share is equal to the ratio of (a) the number
of shares of the Company's Common Stock (including all shares of Common Stock
issued or issuable upon conversion of the Shares) which such Investor is deemed
to be a holder immediately prior to the issuance of such Equity Securities to
(b) the total number of shares of the Company's outstanding Common Stock
(including all shares of Common Stock issued or issuable upon conversion of the
Shares or upon the exercise of any outstanding warrants or options) immediately
prior to the issuance of the Equity Securities. The term "EQUITY SECURITIES"
shall mean (i) any Common Stock, Preferred Stock or other equity security of the
Company, (ii) any security convertible, with or without consideration, into any
Common Stock, Preferred Stock or other equity security (including any option to
purchase such a convertible security), (iii) any security carrying any warrant
or right to subscribe to or purchase any Common Stock, Preferred Stock or other
equity security or (iv) any such warrant or right.

         4.2 EXERCISE OF RIGHTS. If the Company proposes to issue any Equity
Securities, it shall give each Major Investor written notice of its intention,
describing the Equity Securities, the price and the terms and conditions upon
which the Company proposes to issue the same. Each Major Investor shall have
fifteen (15) days from the giving of such notice to agree to purchase its pro
rata share of the Equity Securities for the price and upon the terms and
conditions specified in the notice by giving written notice to the Company and
stating therein the quantity of Equity Securities to be purchased.
Notwithstanding the foregoing, the Company shall not be required to



                                      18.
<PAGE>   23

offer or sell such Equity Securities to any Major Investor who would cause the
Company to be in violation of applicable United States federal securities laws
by virtue of such offer or sale. In connection with any such offer or sale, the
Company will take such actions as are commercially reasonable, or refrain from
taking such actions as is commercially reasonable, as are within its control, so
as to ensure that appropriate exemptions from the registration requirements of
the Securities Act are available.

         4.3 ISSUANCE OF EQUITY SECURITIES TO OTHER PERSONS. If not all of the
Major Investors elect to purchase their pro rata share of the Equity Securities,
then the Company shall promptly notify in writing the Major Investors who do so
elect (each, an "Electing Investor") and shall offer such Major Investors the
right to acquire such unsubscribed shares. Each Electing Investor shall have
five (5) days after receipt of such notice to notify the Company of its election
to purchase all or a portion thereof of the unsubscribed shares. If the Major
Investors fail to exercise in full the rights of first refusal, the Company
shall have ninety (90) days thereafter to sell the Equity Securities in respect
of which the Major Investor's rights were not exercised, at a price and upon
general terms and conditions no more favorable to the purchasers thereof than
specified in the Company's notice to the Major Investors pursuant to Section 4.2
hereof. If the Company has not sold such Equity Securities within ninety (90)
days of the notice provided pursuant to Section 4.2, the Company shall not
thereafter issue or sell any Equity Securities, without first offering such
securities to the Major Investors in the manner provided above.

         4.4 TERMINATION AND WAIVER OF PREEMPTIVE RIGHTS. The preemptive rights
established by this Section 4 shall not apply to, and shall terminate upon the
earlier of (i) the closing of the Company's Initial Offering or (ii)
consummation of an Asset Transfer or Acquisition as defined in the Company's
Restated Certificate of Incorporation. The preemptive rights established by this
Section 4 may be amended, or any provision waived with the written consent of
Major Investors holding sixty percent (60%) of the Registrable Securities held
by all Major Investors, or as permitted by Section 5.6.

         4.5 TRANSFER OF PREEMPTIVE RIGHTS. The preemptive rights of each Major
Investor under this Section 4 may be transferred to the same parties, subject to
the same restrictions as any transfer of registration rights pursuant to Section
2.10.

         4.6 EXCLUDED SECURITIES. The preemptive rights established by this
Section 4 shall have no application to any of the following Equity Securities:

                  (a) Shares of Common Stock (and/or options, warrants or other
Common Stock purchase rights issued pursuant to such options, warrants or other
rights) issued or to be issued after the Original Issue Date (as defined in the
