(the "Company"), Falcon Mezzanine Partners, LP ("Falcon") and Stichting

                                R E C I T A L S :

         A. The Company and the Purchasers have entered into a Purchase
Agreement ("Purchase Agreement"), dated as of the date hereof for the purchase
and sale of $30,000,000 principal amount of the Company's Senior Secured Notes
due 2009 (the "Notes"), 3,060,444 shares (the "Shares") of the Company's common
stock, par value $.001 (the "Common Stock") and Warrants to purchase 15,000,000
shares of Common Stock (the "Warrants").

         B. As a condition to closing of the Purchase Agreement, the parties
have agreed to enter into this Agreement.

         NOW, THEREFORE, in consideration of the above recitals and the mutual
covenants, representations, warranties and agreements set forth herein, and for
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the parties hereto intending to be legally bound do hereby
agree as follows:

         1. DEFINED TERMS. Capitalized terms used but not otherwise defined
herein shall have the meanings assigned to such terms in the Purchase Agreement.

         2. REPRESENTATIONS OF THE PURCHASERS. Each Purchaser represents and
warrants to the Company as follows:

                  (a) Each Purchaser acknowledges and agrees that the
certificates representing the Shares and the Warrant Shares shall bear a legend
in substantially the form appearing below (unless subsequently registered under
the Act):

         "THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT
         BE OFFERED, SOLD, PLEDGED, HYPOTHECATED, ASSIGNED OR TRANSFERRED EXCEPT
         (i) PURSUANT TO A REGISTRATION STATEMENT UNDER THE SECURITIES ACT THAT
         HAS BECOME EFFECTIVE AND IS CURRENT WITH RESPECT TO THESE SECURITIES,
         OR (ii) PURSUANT TO A SPECIFIC EXEMPTION FROM REGISTRATION UNDER THE
         SECURITIES ACT BUT ONLY UPON THE COMPANY FIRST HAVING OBTAINED THE






         WRITTEN OPINION OF COUNSEL TO THE CORPORATION, OR OTHER COUNSEL
         REASONABLY ACCEPTABLE TO THE CORPORATION, THAT THE PROPOSED DISPOSITION
         IS CONSISTENT WITH ALL APPLICABLE PROVISIONS OF THE SECURITIES ACT AS
         WELL AS ANY APPLICABLE "BLUE SKY" OR SIMILAR SECURITIES LAWS."

                  Each Purchaser also acknowledges that the Company may place a
stop transfer order against transfer of any of the Shares or Warrant Shares, if
necessary in the Company's reasonable judgment, in order to assure compliance by
the Purchaser with the terms of the Purchase Agreement and this Agreement.

                  (b) The individual executing this Agreement has appropriate
authority to act on behalf of such Purchaser. This Agreement has been duly
executed and delivered by or on behalf of such Purchaser and constitutes the
valid and binding agreement of such Purchaser, enforceable against such
Purchaser in accordance with its terms (except in all cases as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceeding may be brought).

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to the Purchaser that the Company has full right, power
and authority to enter into this Agreement and this Agreement has been duly
authorized, executed and delivered by the Company and constitutes the legal,
valid and binding agreement of the Company enforceable against the Company in
accordance with its terms (except in all cases as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium, or
similar laws affecting the enforcement of creditors' rights generally and except
that the availability of the equitable remedy of specific performance or
injunctive relief is subject to the discretion of the court before which any
proceeding may be brought).

         4. COVENANTS OF THE PURCHASER. Each Purchaser agrees and covenants that
it will not sell, transfer or make any disposition of any securities of the
Company after the effectiveness of any registration statement relating to a
primary public offering by the Company for a period of time as required by the
managing underwriter of any such offering not to exceed 90 days; provided that
each director, executive officer and 5% or greater shareholder of the Company
shall have agreed to such restrictions for the same time period.

         5. REGISTRATION OF SHARES, WARRANTS AND WARRANT SHARES AND LISTING OF
SHARES AND WARRANT SHARES. The Company hereby agrees with the Purchasers that:

                  (a) (i) The Company shall use its commercially reasonable
efforts to file or cause to be filed, a registration statement (the
"Registration Statement") under the Securities Act, to permit the resale by a
holder thereof of the Shares, Warrants and Warrant Shares and to have such
registration statement declared effective no later than 180 days following the
Closing Date (the "Effectiveness Deadline").



                                       2


                           (ii) The Company shall use its commercially
reasonable efforts to cause such Registration Statement to remain effective
until the earlier to occur of (A) the expiration of the time period referred to
in Rule 144(k) under the Securities Act with respect to the Purchasers and (B)
such time as all the Shares, Warrants and Warrant Shares covered by the
Registration Statement have been sold or are otherwise freely tradable without
registration under the Securities Act (the "Effectiveness Period").

                  (b) In connection with the foregoing, the Company will:

                           (i) Prepare and file with the Securities and Exchange
Commission (the "Commission") a Registration Statement with respect to such
securities and use its commercially reasonable efforts to cause such
Registration Statement to become and remain effective.

                           (ii) 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 keep such Registration
Statement effective and to comply with the provisions of the Securities Act with
respect to the sale or other disposition of all securities covered by such
Registration Statement whenever the holder of such securities shall desire to
sell the same.

                           (iii) Furnish to holder such number of copies of a
summary prospectus or other prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other
documents, as holder may reasonably request in order to facilitate the sale of
the Common Stock owned by holder.

                           (iv) Use its commercially reasonable efforts to
register or qualify the securities covered by such Registration Statement under
applicable blue sky laws, and do such other reasonable acts and things as may be
required in jurisdictions to which such blue sky laws apply; PROVIDED, HOWEVER,
that the Company shall not be obligated to file any general consent to service
of process or qualify as a foreign corporation in any jurisdiction.

                           (v) Furnish at the request of holder, on the date
that the Registration Statement with respect to the Shares, Warrants and Warrant
Shares becomes effective, an opinion, dated as of such date, of the independent
counsel representing the Company for the purposes of such registration,
addressed to the Purchaser stating that such Registration Statement has become
effective under the Securities Act and that 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.

                  (c) All of the expenses incurred in complying with the
foregoing, including, without limitation, all registration and filing fees
(including all expenses incident to filing with the NASD), printing expenses,
fees and disbursements of counsel for the Company, expenses of any special
audits incident to or required by any such registration and expenses of
complying with the securities or blue sky laws or any jurisdictions shall be
paid by the Company.



                                       3


                  (d) The Company shall also use its commercially reasonable
efforts to cause such Common Stock to be listed on the American Stock Exchange
or such other principal national securities exchange on which the shares of
Common Stock are then listed or if the shares are not so listed, on The NASDAQ
Stock Market, if the shares are then listed on such market.

                  (e) Each Purchaser shall furnish to the Company such
information regarding itself, the Shares, Warrants and Warrant Shares
beneficially owned by it and the intended method of disposition of the Shares,
Warrants and Warrant Shares beneficially owned by it as shall be reasonably
required to effect the registration of such Shares, Warrants and Warrant Shares
and shall execute such documents in connection with such registration as the
Company may reasonably request.

         6. INDEMNIFICATION. In the event of any offer of the Shares, Warrants
or Warrant Shares pursuant to the Registration Statement or any amendment
thereof hereof, the Company agrees to indemnify and hold harmless each
Purchaser, each underwriter, if any, of such Shares, Warrants or Warrant Shares,
and each other person, if any, who controls such Purchaser or any such
underwriter within the meaning of the Act, from and against any and all losses,
claims, damages or liabilities (or actions in respect thereof) which arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement under which the Shares,
Warrants and Warrant Shares were registered and offered under the Act or any
prospectus contained therein, 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, and will reimburse
such Purchaser, each such underwriter, and each such controlling person for any
legal or any other expenses reasonably incurred by such Purchaser, such
underwriter or controlling person in connection with the investigation or
defense of any such loss, claim, damage, liability or action, PROVIDED, HOWEVER,
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage, or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
such Registration Statement or such prospectus in reliance upon, and in
conformity with, written information furnished to the Company by such Purchaser,
such underwriter or such controlling person, specifically for use in preparation
thereof, PROVIDED FURTHER, that the Company shall not file any such Registration
Statement or prospectus containing information relating to such Purchaser
without providing the Purchaser with an opportunity to review and, to the extent
incorrect, correct such information.

         In the event of any offer of the Shares, Warrants and Warrant Shares
pursuant to the Registration Statement or any amendment thereof, and to the
extent permitted by applicable law, each Purchaser and each other person, if
any, who controls such Purchaser within the meaning of the Act, agrees to
indemnify and hold harmless the Company, each person who controls the Company
within the meaning of the Act, and each officer and director of the Company from
and against any losses, claims, damages or liabilities, joint or several, to
which the Company, such controlling person or any such officer or director may
become subject under the 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



                                       4


fact contained in such post-effective amendment or other Registration Statement
under which such Shares, Warrants and Warrant Shares were offered or any
prospectus contained therein, 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, which untrue
statement or alleged untrue statement or omission or alleged omission was made
therein in reliance upon, and in conformity with, written information furnished
to the Company by such Purchaser or such controlling person specifically for use
in connection with the preparation thereof (provided that the Company shall have
afforded the Purchaser with an opportunity to review, and to the extent
incorrect, correct such information prior to the filing thereof), and to
reimburse the Company, each such controlling person and each such officer or
director for any legal or any other expenses reasonably incurred by them in
connection with investigating, or defending any such loss, claim, damage,
liability or action; PROVIDED, HOWEVER, that any such indemnification obligation
shall be individual to each Purchaser and limited to an aggregate maximum dollar
amount not to exceed the aggregate dollar amount of the proceeds received by the
Purchasers in any such offering.

         Promptly after receipt by an indemnified party of notice of the
commencement of any action or the assertion of a claim that may be subject to
indemnification hereunder, such indemnified party, if a claim in respect thereof
is to be made against an indemnifying party, will give written notice to such
indemnifying party of the commencement or assertion thereof. Indemnification
provided for under this Section 6 shall not be available to the indemnified
party if it shall fail to give such notice to the indemnifying party (if the
indemnifying party was not aware of the action) to the extent the indemnifying
party was prejudiced by failure to receive such notice, but the omission to give
such notice shall not relieve the indemnifying party from any liability it
otherwise may have to the indemnified party. In case any such action is brought
or such assertion is made against any indemnified party, and it notifies any
indemnifying party of such commencement or assertion, the indemnifying party
will be entitled to participate in and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party, and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such indemnified party for any legal expenses subsequently incurred by
such indemnified party in connection with the defense thereof, other than the
reasonable cost of investigation.

         7. LIQUIDATED DAMAGES. If the Registration Statement covering the
securities required to be filed by the Company pursuant to Section 5 hereof is
not declared effective by the Commission by the Effectiveness Deadline, or the
Registration Statement shall cease to be effective at any time after the
Effectiveness Deadline but prior to the termination of the Effectiveness Period
(a "Noneffective Period"), then the Company shall make the payments to the
Purchaser as provided in the next sentence as liquidated damages and not as a
penalty; PROVIDED HOWEVER, that if after a Registration Statement is declared
effective the Board of Directors of the Company reasonably determines in good
faith that the continued effectiveness of the filing of such Registration
Statement at such time would be materially detrimental to the Company and it is
therefore necessary to suspend the filing of such Registration Statement the
Company may suspend the effectiveness of such Registration Statement for a
period of time not



                                       5


to exceed 90 days in any 12 month period without incurring any liquidated
damages pursuant to this Section 7 for such Noneffective Period. The amount to
be paid by the Company to each Purchaser shall be determined as of each
Computation Date (as defined below), and such amount shall be equal to 1.0% (the
"Liquidated Damage Rate") of the total proceeds received by the Company pursuant
to the amount of the Purchase Price allocated to the Shares purchased by such
Purchaser pursuant to the Purchase Agreement for the period from the
Effectiveness Deadline or the commencement of a Noneffective Period, as
applicable, to the first Computation Date, and for each 30-day period of any
subsequent Computation Dates thereafter, calculated on a pro rata basis to the
date on which the Registration Statement is declared effective by the Commission
(the "Periodic Amount"). The full Periodic Amount shall be paid by the Company
to each Purchaser by wire transfer of immediately available funds within three
days after each Computation Date. As used in this Section 7, "Computation Date"
means the date which is 30 days after the Effectiveness Deadline or the
commencement of a Noneffective Period, as applicable, and, if the Registration
Statement to be filed by the Company pursuant to Section 5 has not theretofore
been declared effective by the Commission, each date which is 30 days after the
previous Computation Date until such Registration Statement is so declared
effective.

         8. RULE 144. The Company covenants that it will file the reports
required to be filed by it under the Act and the Exchange Act and the rules and
regulations adopted by the Commission thereunder (or, if it ceases to be
required to file such reports, it will, upon the request of the Purchaser, make
publicly available other information that fulfills the information requirements
set forth in Rule 144 (c) (2)), and it will take such further action as the
Purchasers may reasonably request, all to the extent required from time to time
to enable the Purchasers to sell the Shares and Warrant Shares without
registration under the Act within the limitation of the exemptions provided by
(a) Rule 144 under the Act, as such Rule may be amended from time to time, or
(b) any similar rule or regulation hereafter adopted by the Commission. Upon the
request of the Purchasers, the Company will deliver to it a written statement as
to whether the Company has complied with such information disclosure and other
requirements.
