                                        2

<PAGE>

registration pursuant to this Section 1.2 after the Company has effected two (2)
                              -----------
such registrations pursuant to this Section 1.2 and such registrations have been
                                    -----------
declared or ordered effective and the sales of such Registrable Securities shall
have closed and the Company shall not be obligated to effect any such
registration pursuant to this Section 1.2 if, in the immediately preceding six
                              -----------
(6) month period, the Company has effected such a registration.

         If the Initiating Holders intend to distribute the Registrable

and the Company shall include such information in the written notice referred to
in Section 1.2(a). In such event, the right of any Holder to include such
   --------------
Holder's 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 (unless otherwise mutually
agreed by a majority in interest of the Initiating Holders and such Holder) to
the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall (together with the Company as provided in
Section 1.8(e)) 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 and reasonably acceptable to the Company.
Notwithstanding any other provision of this Section 1.2, if the underwriter
                                            -----------
advises the Company and the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Company shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Holders thereof, including the Initiating Holders, in such
proportion (as nearly as practicable) among the Holders pro rata based on the
amount of Registrable Securities owned by each Holder.

                1.3.  Shelf Registrations. At any time the holders of fifty
                      -------------------
percent (50%) of the Registrable Securities then outstanding may require that
the Company include the Registrable Securities in an appropriate "shelf"
registration statement pursuant to Rule 415 (or any successor thereto) under the
Securities Act (a "Shelf Registration Statement") and use best efforts to keep
                   ----------------------------
such Shelf Registration Statement effective for sales thereunder for as long as
practicable. The other registration rights set forth in Sections 1.2, 1.4 and
                                                        ------------  ---
1.5 hereof shall be suspended for so long as the Shelf Registration Statement
---
remains effective and usable for the resale of Registrable Securities.

                1.4.  Piggyback Registrations.
                      -----------------------

                      (a)   Notice.  The Company shall notify all Holders of
Registrable Securities in writing at least thirty (30) days prior to filing any
registration statement under the Securities Act for purposes of effecting a
public offering of securities of the Company whether for its own account or the
account of other stockholders or both and will afford each such Holder an
opportunity to include in such registration statement all or any part of the
Registrable Securities then held by such Holder. Each Holder desiring to include
in any such registration statement all or any part of the Registrable Securities
held by such Holder shall, within twenty (20) days after receipt of the
above-described notice from the Company, so notify the Company in writing, and
in such notice shall inform the Company of the number of Registrable Securities
such Holder wishes to include in such registration statement. If a Holder
decides not to include

                                        3

<PAGE>

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
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.

                (b)  Underwriting. If a registration statement under which the
Company gives notice under Section 1.4(a) is for an underwritten offering, then
                           --------------
the Company shall so advise the Holders of Registrable Securities in the notice
delivered under Section 1.4(a). In such event, the right of any such Holder's
                --------------
Registrable Securities to be included in a registration pursuant to this Section
                                                                         -------
1.4 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 managing underwriter or
underwriter(s) selected for such underwriting. Notwithstanding any other
provision of this Agreement, if the managing underwriter(s) determine(s) in good
faith that marketing factors require a limitation of the number of shares to be
underwritten, then the managing underwriter(s) may exclude shares (including
Registrable Securities) from the registration and the underwriting, and the
number of shares that may be included in the registration and the underwriting
shall be allocated, first, to the Company, second, to each of the Holders of
Registrable Securities requesting inclusion of their Registrable Securities in
such registration statement, to be allocated among such Holders pro rata based
on the amount of Registrable Securities owned by each such Holder and third, to
any other holders of the Company's securities; provided, however, that the right
of the underwriters to exclude Registrable Securities from the registration and
underwriting as described above shall be restricted so that the number of
Registrable Securities included in any such registration is not reduced below
twenty-five percent (25%) of the Registrable Securities that the Holders
initially proposed to be registered. Any Registrable Securities excluded or
withdrawn from such underwriting shall be excluded and withdrawn from the
registration.

          1.5.  Form S-3 Registration. If the Company shall be entitled
                ---------------------
as a registrant to use Form S-3 and the holders of at least fifty percent (50%)
of the Registrable Securities then outstanding request that the Company effect a
registration on Form S-3 for shares having an aggregate offering price to the
public of at least Five Million Dollars ($1,000,000), then the Company will:

                (a)  promptly give written notice of the proposed registration
to all other Holders of Registrable Securities; and

                (b)  as soon as practicable, use its best efforts to effect the
registration of the sale of the Registrable Securities specified in such
request, together with all or such portion of the Registrable Securities of any
Holder or Holders joining in such request as are specified in a written request
received by the Company within thirty (30) days after written notice from the
Company is given under Section 1.5(a) above; provided, however, that the Company
                       --------------
shall not be obligated to effect any such registration pursuant to this Section
                                                                        -------
1.5 if, in the immediately preceding twelve (12) month period, the Company has
---
effected three such registrations.

<PAGE>

                    (c) A registration under this Section 1.5 shall not
                                                  -----------
constitute a registration under Section 1.2 nor shall a registration statement
                                -----------
under Section 1.2 constitute a registration under this Section 1.5.
      -----------                                      -----------

               1.6. Initial Registration on Form S-3. Notwithstanding anything
                    --------------------------------
to the contrary contained herein, the Company shall, as promptly as practicable
after the Closing Date, prepare and file a Registration Statement covering the
Designated Securities, and use its best efforts to effect such registration of
the Designated Securities on or prior to the Funding Date (the "Initial

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,
following such notification, promptly deliver to each Holder and each such
underwriter that number of copies of all amendments or supplements referred to

"Violation"):
 ---------

                         (i)   any untrue statement or alleged untrue statement
of a material fact contained or incorporated by reference in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto;

                         (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 federal or state securities law or
any rule or regulation promulgated under the Securities Act, the Exchange Act or
any federal or state securities law in connection with the offering covered by
such registration statement;

                     (b) and the Company will reimburse each such Holder,
partner, member, officer or director, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the indemnity agreement contained in this
subsection 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) a
Violation which occurs in reliance upon and in conformity with written
information furnished in writing and expressly stated for use in connection with
such registration by such Holder, partner, member, officer, director,
underwriter or controlling person of such Holder, or (B) a Violation which
occurs as a result of an untrue statement of a material fact contained or
incorporated by reference in such registration statement that has been corrected
in a subsequent prospectus delivered to such Holder prior to disposition by such
Holder of its Registrable Securities in accordance with Section 1.8(f) hereof.

<PAGE>

               (c) By Selling Holders. To the extent permitted by law, each
selling Holder will, severally and not jointly, if Registrable Securities held
by such Holder are included in the securities as to which such registration is
being effected, indemnify and hold harmless the Company, each of its directors,
each of its officers who have signed the registration statement, each person, if
any, who controls the Company within the meaning of the Securities Act, any
underwriter (as defined in the Securities Act) and any other Holder selling
securities under such registration statement or any of such other Holder's
partners, members, directors or officers or any person who controls such
underwriter or other Holder within the meaning of the Securities Act or the
Exchange Act, against any losses, claims, damages or liabilities (joint or
several) to which the Company or any such director, officer, controlling person,
underwriter or other such Holder, or a member, partner, director, officer or
controlling person of such underwriter or other Holder may become subject under
the Securities Act, the Exchange Act, any federal or state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
federal or state securities law in connection with the offering covered by such
registration statement, 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 by an instrument duly executed by such Holder and stated to be
specifically for use in such registration; and each such Holder will reimburse
any legal or other expenses reasonably incurred by the Company or any such
director, officer, controlling person, underwriter or other Holder, partner,
member, officer, director or controlling person of such other Holder or
underwriter in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
contained in this subsection 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 Holder, which consent shall not be unreasonably
withheld; and provided further, that the total amounts payable in indemnity by a
Holder under this Section 10(c) in respect of any Violation shall not exceed the
                  -------------
net proceeds received by such Holder in the registered offering out of which
such Violation arises.

               (d) Notice. Promptly after receipt by an indemnified party 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 1.10, 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
the defendants include both the indemnifying party and the indemnified party and
the indemnified party shall have reasonably concluded that there may be
reasonable defenses available to it which are different from or additional to
those available to the indemnifying party or if the interests of the indemnified
party reasonably may be deemed to conflict with the interests of the
indemnifying party. 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
                                                                        -------
1.10 to the extent it is prejudiced thereby, but the omission so to deliver
----
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under Section 1.10.
                                                               ------------

                     (e) Contribution. In order to provide for just and
equitable contribution to joint liability under the Securities Act in any case
in which either (A) any Holder exercising rights under this Agreement, or any
controlling person of any such Holder, makes a claim for indemnification
pursuant to this Section 1.10 but it is judicially determined (by the entry of a
                 ------------
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 1.10 provides for indemnification in such case, or (B) contribution
     ------------
under the Securities Act may be required on the part of any such selling Holder
or any such controlling person in circumstances for which indemnification is
provided under this Section 1.10, then, and in each such case, the Company or
                    ------------
such Holder shall contribute to the aggregate losses, claims, damages or
liabilities as is appropriate to reflect not only the relative benefits received
by the indemnified party and the indemnifying party, but also the relative fault
of the indemnified party and the indemnifying party, as well as any other
relevant equitable considerations. The relative fault of such indemnifying party
and indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action; provided,
however, that, in any such case, (1) no such Holder shall be required to
contribute any amount in excess of the public offering price of all such
Registrable Securities offered and sold by such Holder pursuant to such
registration statement; and (2) no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
                       -------------
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                     (f) Survival. The obligations of the Company and Holders
under this Section 1.9 shall survive the completion of any offering of
           -----------
Registrable Securities in a registration statement and the termination of this
Agreement.

               1.11. Limitations on Subsequent Registration Rights. From and
                     ---------------------------------------------
after the date of this Agreement, without the prior written consent of the
Holders of a majority of the Registrable Securities then outstanding, the
Company shall not enter into any agreement with any holder or prospective holder
of any securities of the Company that would allow such holder or prospective
holder to have registration rights superior to, or which limit in any way the
registration rights of the Holders granted hereby.

               1.12. Reporting and Information. With a view to making available
                     -------------------------
the benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Registrable Securities to the public without
registration, the Company agrees to:

                         (i)  make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times;

                         (ii) file with the SEC in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Exchange Act (whether or not it shall be required to make such Exchange Act
Reports) and shall comply with all other public information reporting
requirements of the SEC as a condition to the availability of an

                                       9

<PAGE>

exemption from the Securities Act (under Rule 144 thereof, as amended from time
to time, or successor rule thereto or otherwise) for the sale of Common Stock by
the Holders;

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

                         (iv)  cooperate with the Holders in supplying such
information as may be necessary for the Holders to complete and file any
information reporting forms presently or hereafter required by the Commission as
a condition to the availability of an exemption from the Securities Act (under
Rule 144 thereof or otherwise) for the sale of Common Stock by the Holders.

after October 30, 2001, the Company shall retire One Dollar ($1) of principal
and interest for every Two Dollars ($2) in gross proceeds received on the same
business day of the Company's receipt of the gross proceeds of such financings;

             c.      In the event that Sands Brothers or any of its affiliates
