or distribution of any part thereof, and that Purchaser has no present intention
of selling, granting any participation in, or otherwise distributing the same.

intended to describe the aspects of the Company's business which it believes to
be material.

that if an exemption from registration or qualification is available, it may be
conditioned on various requirements including, but not limited to, the time and
manner of sale, the holding period for the Securities, and on requirements
relating to the Company which are outside of such Purchaser's control, and which
the Company may not be able to satisfy.

                  3.5  LEGENDS. Purchaser understands that the Securities and
any securities issued in respect of or exchange for the Securities, may bear one
or all of the following legends:

                       (a)  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR

FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER

appropriate similar rule that may be adopted by the SEC) under the Securities
Act covering the Converted Common Stock (including any amendment thereto, the
"SHELF REGISTRATION") not later than sixty (60) days after the Closing (the
"FILING DATE"). The Shelf Registration shall be on Form S-3 or another

resale by the Purchaser from time to time. The Purchaser agrees to furnish

resumed, (ii) has received copies of a supplemental or amended prospectus, if
applicable, and (iii) has received copies of any additional or supplemental
filings which are incorporated or deemed to be incorporated by reference in such
prospectus. The Purchaser shall treat any information relating to a Suspension
Period, including its receipt of notice of a Suspension Period, as confidential
information of the Company, and shall not use or disclose any such information
except with the prior written consent of the Company.

obligations under this Section 4, in connection with the registration of the
Converted Common Stock on the Shelf Registration, the Company shall:

                           (a)  As promptly as practicable after becoming aware
of such event, notify the Purchaser of the occurrence of any event, as a result
of which the prospectus included in the Shelf Registration, 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,
in light of the circumstances under which they were made, not misleading, and
promptly prepare an amendment to the Shelf Registration and supplement to the
prospectus to correct such untrue statement or omission, and deliver a number of
copies of such supplement and amendment to the Purchaser as the Purchaser may
reasonably request; and

                           (b)  As promptly as practicable after becoming aware
of such event, notify the Purchaser who holds Converted Common Stock being sold
of the issuance by the SEC of any stop order or other suspension of the
effectiveness of the Shelf Registration at the earliest possible time and take
all lawful action to effect the withdrawal, recession or removal of such stop
order or other suspension; and

                           (c)  With a view to making available to the Purchaser
the benefits of Rule 144 under the Securities Act ("RULE 144") and any other
rule or regulation of the SEC that may at any time permit the Purchaser to sell
Converted Common Stock to the public without registration or pursuant to
registration, the Company covenants and agrees to use its reasonable commercial
efforts to: (i) make and keep public information available, as those terms are

timely manner all reports and other documents required of the Company under the

                  4.6  INDEMNIFICATION AND CONTRIBUTION.

                       (a)  The Company agrees to indemnify and hold
harmless the Purchaser from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which the
Purchaser (including for such purpose its officers, directors, partners,
attorneys and agents) may become subject (under the Securities Act or otherwise)
to the extent such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, any untrue
statement of a material fact contained in the Shelf Registration or the
prospectus (including any supplement) contained therein or arise out of, or are
based upon, the omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in light of the
circumstances under which they were made in the case of the prospectus), not
misleading, or to the extent arising out of any failure by the Company to
fulfill any undertaking included in the Shelf Registration, and the Company
will, on a quarterly basis, reimburse the Purchaser for any legal or other
expenses reasonably incurred in investigating or defending any such action,
proceeding or claim; provided, however, that the Company shall not be liable in
any such case to the extent that such loss, claim, damage or


                                       7



liability arises out of, or is based upon (i) an untrue statement made in such
Shelf Registration in reliance upon and in conformity with information furnished
to the Company by or on behalf of the Purchaser, (ii) the failure of the
Purchaser to comply with the covenants and agreements contained in this
Agreement, or (iii) any untrue statement in any prospectus that is corrected in
any subsequent prospectus that was delivered to the Purchaser prior to the
pertinent sale or sales by the Purchaser.

                           (b)  Each Purchaser, severally and not jointly,
agrees to indemnify and hold harmless the Company (including for such purpose
its officers, directors, partners, attorneys and agents) from and against any
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) to which the Company may become subject (under the Securities Act or
otherwise) to the extent such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the Shelf
Registration or the prospectus (including any supplement) contained therein or
to the extent arising 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 (in light of the circumstances under
which they were made in the case of the prospectus), not misleading, in each
case, to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of the Purchaser specifically for use in preparation of the Shelf
Registration.

                           (c)  Promptly after receipt by any indemnified
person of a notice of a claim or the beginning of any action in respect of which
indemnity is to be sought against an indemnifying person pursuant to this
Section 4.6, such indemnified person shall notify the indemnifying person in
writing of such claim or of the commencement of such action (but the omission to
so notify the indemnifying party shall not relieve it from any liability that it
otherwise may have to the indemnified party, except to the extent that the
indemnifying party is materially prejudiced and forfeits substantive rights and
defenses by reason of such failure), and, subject to the provisions hereinafter
stated, in case any such action shall be brought against an indemnified person
and the indemnifying person shall have been notified thereof, the indemnifying
person shall be entitled to participate therein, and, in the case of any claim
as to which both the indemnified party and the indemnifying party are parties,
to the extent that it shall wish, the indemnifying party may assume the defense
thereof, with counsel reasonably satisfactory to the indemnified person. After
notice from the indemnifying person to such indemnified person of the
indemnifying person's election to assume the defense thereof, the indemnifying
person shall not be liable to such indemnified person for any legal expenses
subsequently incurred by such indemnified person in connection with the defense
thereof; provided, however, that if there exists or shall exist a conflict of
interest that would make it inappropriate in the reasonable judgment of the
indemnified person for the same counsel to represent both the indemnified person
and such indemnifying person or any affiliate or associate thereof, the
indemnified person shall be entitled to retain its own counsel at the expense of
such indemnifying person. If the indemnifying party shall assume the defense of
any such claim, it shall not, without prior written consent of the indemnified
party (which consent shall not unreasonably be withheld), settle or compromise
any such claim or consent to the entry of any


                                       8



judgment that does not include an unconditional release of the indemnified party
from all liabilities with respect to such claim or judgment. Further, no
indemnifying party shall have any obligation with respect to any settlement
entered into by an indemnified party without the prior written approval of this
indemnifying party.

                           (d)  If the indemnification provided for in this
Section 4.6 is unavailable to or insufficient to hold harmless an indemnified
party under subsection (a) or (b) above in respect of any losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) referred
to therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand and the Purchaser
on the other in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities (or actions in respect thereof), as
well as any other relevant equitable considerations. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or the Purchaser on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Purchaser agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, or liabilities (or actions in respect thereof) referred to
above in this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. 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.

                  4.7  NASDAQ NMS LISTING. The Company shall use its reasonable
commercial efforts to cause the Converted Common Stock to be listed for
inclusion on the Nasdaq National Market System no later than on the Effective
Date.

         5.       FINDER'S FEE. At the Closing, the Company shall pay to the
Purchaser a finders' fee in the amount of $800,000 in consideration of the
Purchaser's arrangement of the financing.

         6.       CONDITIONS OF THE PURCHASER'S OBLIGATIONS AT THE CLOSING. The
obligations of the Purchaser to the Company under this Agreement are subject to
the fulfillment, on or before the Closing, of each of the following conditions,
unless otherwise waived:

                  6.1  REPRESENTATIONS AND WARRANTIES. The representations and
warranties of the Company contained in Section 2 shall be true and correct in
all material respects on and as of the Closing with the same effect as though
such representations and warranties had been made on and as of the date of the

conditions of this Agreement, must be in writing and shall be effective only to
