instructions to any transfer agent of the Registrable Securities in order to
implement the restrictions on transfer established in this Agreement.

         Section 4. NOTICE AND OTHER REQUIREMENT OF TRANSFER. No Holder will
make any sale, assignment, transfer, pledge or other disposition of all or any
portion of any Registrable Securities unless:

         (a) The intended sale, assignment, transfer, pledge or other
disposition complies with the provisions of Section 2;

         (b) There is in effect a registration statement under the Securities
Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

         (c) As an alternative to Section 4(b), (i) such Holder has notified the
Company of the proposed disposition and has furnished the Company with a
detailed statement of the circumstances surrounding the proposed disposition,
including the name and address of the buyer and identifying the Registrable
Securities with respect to which such rights are being assigned, and (ii) the
buyer, as a condition to the effectiveness of such assignment, has executed a
counterpart of this Agreement agreeing to be treated as a


                                       15
<PAGE>

Holder hereunder; and, if the Company reasonably requests, such Holder shall
also furnish the Company with an opinion of counsel, reasonably satisfactory to
the Company, that such disposition does not require registration of such shares
under the Securities Act.

         Section 5. PIGGYBACK REGISTRATION.

         (a) If at any time, or from time to time, prior to the termination of
this Agreement pursuant to Section 12 hereof, the Company shall determine to
register any shares of Common Stock for its own account or the account of any of
its shareholders, other than: (i) a transaction relating solely to the sale of
convertible debt instruments; (ii) a registration on Form S-4 or S-8 or another
form not available for registering the Registrable Securities for sale to the
public; or (iii) any registration comprised in whole or in substantial part of
shares underlying stock options granted by the Company or its predecessor, the
Company will give to the Holders written notice as soon as practicable prior to
filing the registration statement and include in such registration, and in any
underwriting involved therein, all the Registrable Securities specified in one
or more written requests which have been made within 15 days after receipt of
such written notice from the Company by any of the Holders, except as set forth
in Section 5(b).

         (b) If the registration is for a registered public offering involving
an underwriting, the Company shall so advise each Holder as a part of the
written notice given pursuant to Section 5(a). In such event, the right of each
Holder to registration pursuant to this Section 5 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. If any
Holder proposes to distribute his securities through such underwriting, he shall
(together with the Company and the other holders distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting by the
Company (provided that the terms of such underwriting agreement must be
consistent with this Agreement). Notwithstanding any other provision of this
Section 5, if the managing underwriter determines that marketing factors require
a limitation of the number of shares to be underwritten, the managing
underwriter may limit the number of Registrable Securities to be included in the
registration and underwriting (provided that no shares held by officers and
directors of the Company, other than Registrable Securities that may be owned by
officers and directors, are included in the registration and underwriting). The
Company shall so advise each of the Holders and the other holders distributing
their securities through such underwriting pursuant to piggyback registration
rights similar to this Section 5, and the number of shares of Registrable
Securities and other securities that may be included in the registration and
underwriting shall be allocated among such Holder and other holders in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities held by each Holder and other securities held by other holders at the
time of filing the registration statement. If any of the Holders disapproves of
the terms of any such underwriting, he may elect to withdraw therefrom by
written notice to the Company and


                                       16
<PAGE>

the managing underwriter. Any Registrable Securities excluded or withdrawn from
such underwriting shall be withdrawn from such registration.

         (c) Notwithstanding any other provision of this Agreement, the
Company's obligation to file a registration statement, or cause such
registration statement to become and remain effective, shall be suspended for a
period not to exceed 90 days (and for periods not exceeding, in the aggregate,
180 days in any 12-month period) if there exists at the time material non-public
information relating to the Company which, in the reasonable opinion of the
Company, should not be disclosed.

         Section 6. EXPENSES OF REGISTRATION. All expenses incurred in
connection with registrations pursuant to Section 5, including without
limitation all registration, filing and qualification fees, printing expenses,
fees and disbursements of counsel for the Company and independent accounts for
the Company and expenses of any special audits of the Company's financial
statements incidental to or required by such registration, fees of the National
Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents
and registrars' fees shall be borne by the Company, except that the Company
shall not be required to pay underwriters' fees, discounts or commissions
relating to Registrable Securities or fees of one separate legal counsel for all
of the Holders.

         Section 7. REGISTRATION PROCEDURES. In the case of each registration
effected by the Company pursuant to this Agreement, the Company will keep the
Holders participating therein advised in writing as to the initiation of each
registration and as to the completion thereof. At its expense, the Company will:

         (a) file and keep such registration pursuant to Section 5 continuously
effective for periods of 180 days or, in each case, such reasonable period
necessary to permit the Holders to complete the distribution described in the
registration statement relating thereto;

         (b) promptly prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to comply with the provisions of the Securities
Act, and to keep such registration statement effective for that period of time
specified in Section 7(a);

         (c) furnish such number of the registration statement and the
prospectus included therein, including preliminary prospectuses and other
documents incident thereto as the Holders from time to time may reasonably
request;

         (d) use reasonable best efforts to obtain the withdrawal of any order
suspending the effectiveness of a registration statement, or the lifting of any
suspension of the qualification of any of the Registrable Securities for sale in
any jurisdiction, at the earliest possible moment;


                                       17
<PAGE>

         (e) register or qualify such Registrable Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions as the Holders or

things that may be necessary or desirable to enable the Holders to consummate
the public sale or other disposition in such jurisdiction of the Registrable
Securities;

         (f) cause all Registrable Securities covered by such registrations to
be listed on each securities exchange, including the American Stock Exchange, on

agreements in customary form) and take all such other actions as the Holders or
the underwriters, if any, reasonably, request in order to expedite or facilitate
the disposition of such Registrable Securities (including, without limitation,
effecting a stock split or a combination of shares);

         (i) make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement, and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement and afford
such entities the reasonable opportunity to review and comment thereon and
participate in the preparation of such registration statement;

         (j) if the offering is underwritten, at the request of the Holders of
Registrable Securities to furnish on the date that Registrable Securities are
delivered to the underwriters for sale pursuant to such registration: (i) an
opinion dated such date of counsel representing the Company for the purposes of
such registration, addressed to the underwriters and to the Holders, stating
that such registration statement has become effective under the Securities Act
and that (A) to the best knowledge of such counsel, no stop order suspending the
effectiveness thereof has been issued and no proceedings for that purpose have
been instituted or are pending or contemplated under the Securities Act, (B) the
registration statement, the related prospectus and each amendment or supplement
thereof comply as to form in all material respects with the requirements of the
Securities Act and the applicable rules and regulations of the Securities and
Exchange Commission thereunder (except that such counsel need not express any
opinion as to


                                       18
<PAGE>

financial statements or other financial data contained therein) and (C) to such
other effects as reasonably may be requested by counsel for the underwriters or

independent public accountants retained by the Company, addressed to the
underwriters and to such seller, stating that they are independent public
accountants within the meaning of the Securities Act and that, in the opinion of
such accountants, the financial statements of the Company included in the
registration statement or the prospectus, or any amendment or supplement
thereof, comply as to form in all material respects with the applicable
accounting requirements of the Securities Act, and such letter shall
additionally cover such other financial matters (including information as to the
period ending no more than five business days prior to the date of such letter)
with respect to such registration as such underwriters reasonably may request;

         (k) notify the Holders, at any time a prospectus covered by such
registration statement is required to be delivered under the Securities Act, of
the happening of any event of which it has knowledge 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

         (1) take such other actions as shall be reasonably requested by the
Holders.

         Section 8. INDEMNIFICATION.

         (a) If the Company registers any of the Registrable Securities under
the Securities Act pursuant to Section 5, the Company will indemnify and hold
harmless the Holders of such Registrable Securities thereunder, each underwriter
of such Registrable Securities thereunder and each other person, if any, who
controls any Holder or underwriter within the meaning of the Securities Act,
against any losses, claims, damages or liabilities, joint or several, to which
such Holders, underwriter or controlling persons may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such Registrable Securities were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereof, or arise
out of or are based upon 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 any violation by the Company of any rule or
regulation promulgated under the Securities Act or any state securities law
applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, and will reimburse the
Holders, each of their respective officers, directors and partners, and each
person controlling any of the Holders, each such underwriter and each person who
controls any such underwriter, for any reasonable legal and any other expenses
incurred in connection with investigating,


                                       19
<PAGE>

defending or settling any such claim, loss, damage, liability or action,
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage or liability arises out of or is based on any
untrue statement or omission based upon written information furnished to the
Company by an instrument duly executed by any of the Holders or underwriter
specifically for use therein.

         (b) Each Holder will, if Registrable Securities held by or issuable to
such Holder are included in the securities as to which such registration is
being effected, severally and not jointly, indemnify and hold harmless the
Company, each of its directors, each officer who signs the registration
statement, each underwriter, if any, of the Company's securities covered by such
a registration statement, each person who controls the Company and each
underwriter within the meaning of the Securities Act, against all claims,
losses, expenses, 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, such
directors, officers, partners, persons or underwriters for any reasonable legal
or any other expenses incurred by them in connection with investigating,
defending or settling any such claim, loss, damage, liability or action, 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 an instrument duly executed by such Holder specifically for use
therein; PROVIDED, that the total amount for which any Holder, its officers,
directors and partners, and any person controlling such Holder, shall be liable
under this Section 8(b) shall not in any event exceed the proceeds (net of
underwriting discounts and commissions) received by such Holder from the sale of
Registrable Securities sold by such Holder in such registration.

         (c) Each party entitled to indemnification under this Section 8 (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 claims as to which indemnity may be sought, and
shall permit the Indemnifying Party to assume the defense of any such claim or
any litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations hereunder, unless such failure resulted in actual detriment to
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 of such claim or
litigation.


                                       20
<PAGE>

         (d) Notwithstanding the foregoing, to the extent that the provisions on
indemnification contained in the underwriting agreements entered into among the
selling Holders, the Company and the underwriters in connection with the
underwritten public offering are in conflict with the foregoing provisions, the
provisions in the underwriting agreement shall be controlling as to the
Registrable Securities included in the public offering; PROVIDED, that if, as a
result of this Section 8(d), the Holders, and any persons controlling such
Holders is held liable for an amount which exceeds the aggregate proceeds
received by such Holders from the sale of Registrable Securities included in a
registration, as provided in Section 8(b), pursuant to such underwriting
agreement (the "Excess Liability"), the Company shall reimburse any such Holders
for such Excess Liability.

         (e) If the indemnification provided for in this Section 8 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such `indemnified party
thereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense 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 hand in
connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense as well as any other relevant equitable
considerations. The relevant fault of the indemnifying party and the indemnified
party shall be determined 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, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Notwithstanding the foregoing, the amount that any Holder shall be obligated to
contribute pursuant to this Section 8(e) shall be limited to an amount equal to
the proceeds to such Holder of the Registrable Securities sold pursuant to the
registration statement which gives rise to such obligation to contribute (less
the aggregate amount of any damages which such Holder has otherwise been
required to pay in respect of such loss, claim, damage, liability or action or
any substantially similar loss, claim, damage, liability or action arising from
the sale of such Restricted Securities).

         (f) The indemnification provided by this Section 8 shall be a
continuing right to indemnification and shall survive the registration and sale
of any securities by any person entitled to indemnification hereunder and the
expiration or termination of this Agreement.

         Section 9. LOCKUP AGREEMENT. In consideration for the Company agreeing
to its obligations under this Agreement, and subject to the provisions of
Section 2, each of the Holders agrees in connection with any registration of any
Registrable Securities in an underwritten offering, at the request of the
Company or the underwriters managing any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any Registrable Securities (other than
those included in the registration) without the prior


                                       21
<PAGE>

written consent of the Company or such underwriters, as the case may be, for
such period of time from the effective date of such registration as the Company
and the underwriters may specify, so long as all stockholders of the Company
holding more than one percent (1 %) of the outstanding common stock and all
officers and directors of the Company are bound by a comparable obligation.

         Section 10. HOLDER'S COOPERATION .

         (a) Each Holder shall promptly furnish to the Company such information
regarding such Holder and the distribution proposed by such Holder as the
Company may request in writing and as shall be required in connection with any
registration referred to herein.

         (b) Each Holder holding shares included in the registration will not
(until further notice by the Company) effect sales thereof (or deliver a
prospectus to any purchaser) after receipt of telegraphic or written notice from
the Company to suspend sales to permit the Company to correct or update a
registration statement or prospectus. At the end of the period during which the
Company is obligated to keep the registration statement current and effective as
described in Section 7(a), each of the Holders holding shares of Registrable
Securities included in the registration shall discontinue sales of shares
pursuant to such registration statement upon receipt of notice from the Company
of its intention to remove from registration the shares of Registrable
Securities covered by such registration statement that remain unsold, and each
of the Holders shall notify the Company of the number of such shares registered
that remain unsold immediately upon receipt of such notice from the Company.

         Section 11. RULE 144. 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:

         (a) make and keep public information available, as those terms are
understood and defined in Rule 144; and

         (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 Securities Act
and the Exchange Act.

         Section 12. TERMINATION OF RIGHTS.

         (a) The rights of any Holder to cause the Company to register
securities under Section 5 shall terminate at such time as such Holder is able
to dispose of all of the Registrable Securities owned by him at such time in one
three-month period pursuant to the provisions of Rule 144.

         (b) Notwithstanding the provisions of Section 12(a), all rights of the
Holders under Section 5 of this Agreement shall terminate at 5:00 P.M. Eastern
time on the date three years after the date of this Agreement.

represents and warrants to the Holders as follows:

indenture, agreement or other instrument or result in the creation or imposition
of any lien, charge or encumbrance of any nature whatsoever upon any of the
properties or assets of the Company.

         (b) This Agreement has been duly executed and delivered by the Company
and constitutes the legal, valid and binding obligation of the Company,
enforceable in accordance with its terms, subject to (i) applicable bankruptcy,
