notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation (with or
without notice, lapse of time or both) of, any agreement, credit facility, debt
or other instrument (evidencing a Company or Subsidiary debt or otherwise) or
other understanding to which the Company or any Subsidiary is a party or by
which any property or asset of the Company or any Subsidiary is bound or
affected, or (iii) result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental
authority to which the Company or a Subsidiary is subject (including federal and
state securities laws and regulations), or by which any property or asset of the
Company or a Subsidiary is bound or affected; except in the case of each of
clauses (ii) and (iii), such as could not, individually or in the aggregate,
have or result in a Material Adverse Effect.

                  (e) Filings, Consents and Approvals. Neither the Company nor
any Subsidiary is required to obtain any consent, waiver, authorization or order
of, give any notice to, or make any filing or registration with, any court or
other federal, state, local or other governmental authority or other Person in
connection with the execution, delivery and performance by the Company of the
Transaction Documents, other than (i) the filings required under Section 4.8 and
the required filing of the First Certificate of Designation pursuant to Section
2.2 and the Second Certificate of Designation pursuant to Section 2.3, (ii) the
filing with the Commission of the Conversion Shares Registration Statement and
the Note Shares Registration Statement, (iii) the application(s) to each Trading
Market for the listing of the Underlying Shares for trading thereon in the time
and manner required thereby, (iv) applicable Blue Sky filings, (v) shareholder
approval under the circumstances contemplated by Sections 4.5(f) and 4.5(g)
hereof, and (vi) in all other cases where the failure to obtain such consent,
waiver, authorization or order, or to give such notice or make such filing or
registration could not have or result in, individually or in the aggregate, a
Material Adverse Effect (collectively, the "Required Approvals").

                  (f) Issuance of the Securities. The Securities (including the
Underlying Shares) are duly authorized and, when issued and paid for in
accordance with the Transaction Documents, will be duly and validly issued,
fully paid and nonassessable, free and clear of all Liens created by the
Company. The Company has reserved from its duly authorized capital stock a
number of shares of Common Stock to be issued upon conversion or exercise of the
Securities at least equal to the Required Minimum on the date hereof.

                  (g) Capitalization. The number of shares and type of all
authorized, issued and outstanding capital stock of the Company is set forth in
Schedule 3.1(g). Except as set forth in Schedule 3.1(g), no securities of the
Company are entitled to preemptive or similar rights, and no Person has any
right of first refusal, preemptive right, right of participation, or any similar
right to participate in the transactions contemplated by the Transaction






                                        9
<PAGE>

Documents. Except as a result of the purchase and sale of the Securities and
except as disclosed in Schedule 3.1(g), there are no outstanding options,
warrants, script rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities, rights or obligations convertible into or
exchangeable for, or giving any Person any right to subscribe for or acquire,
any shares of Common Stock, or contracts, commitments, understandings or
arrangements by which the Company or any Subsidiary is or may become bound to
issue additional shares of Common Stock, or securities or rights convertible or
exchangeable into shares of Common Stock. Except as disclosed in Schedule
3.1(g), the issue and sale of the Securities (including the Underlying Shares)
will not obligate the Company to issue shares of Common Stock or other
securities to any Person (other than the Purchasers) and will not result in a
right of any holder of Company securities to adjust the exercise, conversion,
exchange or reset price under such securities. To the knowledge of the Company,
except for the Purchasers or as disclosed in Schedule 3.1(g), no Person or group
of related Persons beneficially owns (as determined pursuant to Rule 13d-3 under
the Exchange Act), or has the right to acquire, by agreement with or by
obligation binding upon the Company, beneficial ownership of in excess of 5% of
the outstanding Common Stock.

                  (h) SEC Reports; Financial Statements. The Company has filed
all reports required to be filed by it under the Securities Act and the Exchange
Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years
preceding the date hereof (or such shorter period as the Company was required by
law to file such material) (the foregoing materials, together with all exhibits
thereto, being collectively referred to herein as the "SEC Reports" and,
together with the Schedules to this Agreement, the "Disclosure Materials") on a
timely basis or has received a valid extension of such time of filing and has
filed any such SEC Reports prior to the expiration of any such extension. As of
their respective dates, the SEC Reports complied in all material respects with
the requirements of the Securities Act and the Exchange Act and the rules and
regulations of the Commission promulgated thereunder, and none of the SEC
Reports, when filed, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The financial statements of the Company included
in the SEC Reports complied in all material respects with applicable accounting
requirements and the rules and regulations of the Commission with respect
thereto as in effect at the time of filing. Such financial statements have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis during the periods involved ("GAAP"), except as may be
otherwise specified in such financial statements or the notes thereto, and
fairly present in all material respects the financial position of the Company
and its consolidated subsidiaries as of and for the dates thereof and the
results of operations and cash flows for the periods then ended, subject, in the
case of unaudited statements, to normal, immaterial, year-end audit adjustments.
All material agreements to which the Company or any Subsidiary is a party or to
which the property or assets of the Company or any Subsidiary are subject have
been filed as exhibits to the SEC Reports as required under the Exchange Act.

                  (i) Material Changes. Since the date of the latest audited
financial statements included within the SEC Reports, except as specifically
disclosed in the Company's Annual Report filed with the SEC for the year ended
December 31, 2000 and any quarterly reports filed with the SEC for any period
thereafter, (i) there has been no event, occurrence or development that has had





                                       10
<PAGE>

or that could result in a Material Adverse Effect, (ii) the Company has not
incurred any liabilities (contingent or otherwise) other than (A) trade payables
and accrued expenses incurred in the ordinary course of business consistent with
past practice and (B) liabilities not required to be reflected in the Company's
financial statements pursuant to GAAP or required to be disclosed in filings
made with the Commission, (iii) the Company has not altered its method of
accounting or the identity of its auditors, (iv) the Company has not declared or
made any dividend or distribution of cash or other property to its stockholders
or purchased, redeemed or made any agreements to purchase or redeem any shares
of its capital stock, and (v) the Company has not issued any equity securities
to any officer, director or Affiliate, except pursuant to existing Company stock
option plans.

                  (j) Litigation. There is no action, suit, inquiry, notice of
violation, proceeding or investigation pending or, to the knowledge of the
Company, threatened against or affecting the Company, any Subsidiary or any of
their respective properties before or by any court, arbitrator, governmental or
administrative agency or regulatory authority (federal, state, county, local or
foreign) (collectively, an "Action") which (i) adversely affects or challenges
the legality, validity or enforceability of any of the Transaction Documents or
the Securities or (ii) could, if there were an unfavorable decision,
individually or in the aggregate, have or result in a Material Adverse Effect.
Neither the Company nor any Subsidiary, nor to the knowledge of the Company, any
director or officer thereof, is or has within the last five years been the
subject of any Action involving a claim of violation of or liability under
federal or state securities laws or a claim of breach of fiduciary duty. The
Company does not have pending before the Commission any request for confidential
treatment of information, and the Company does not expect to make any such
request prior to the Required Effectiveness Date. There has not been, and to the
knowledge of the Company, there is not pending or contemplated, any
investigation by the Commission involving the Company. The SEC has not issued
any stop order or other order suspending the effectiveness of any registration
statement filed by the Company or any Subsidiary under the Exchange Act or the
Securities Act. No strike, work stoppage, slow down or other material labor
problem exists or, to the knowledge of the Company, is threatened or imminent
with respect to any of the employees of the Company or the Subsidiaries.

                  (k) Compliance. Neither the Company nor any Subsidiary (i) is
in default under or in violation of (and no event has occurred that has not been
waived that, with notice or lapse of time or both, would result in a default by
the Company or any Subsidiary under), nor has the Company or any Subsidiary
received notice of a claim that it is in default under or that it is in
violation of, any evidence of indebtedness, indenture, loan or credit agreement
or any other agreement or instrument to which it is a party or by which it or
any of its properties is bound (whether or not such default or violation has
been waived), (ii) is in violation of any order of any court, arbitrator or
governmental body, or (iii) is or has been in violation of any statute, rule or
regulation of any governmental authority, including without limitation all
foreign, federal, state and local laws relating to taxes, environmental
protection, occupational health and safety, product quality and safety and
employment and labor matters, except in each case as could not, individually or
in the aggregate, have or result in a Material Adverse Effect.






                                       11
<PAGE>

                  (l) Regulatory Permits. The Company and the Subsidiaries
possess all certificates, authorizations and permits issued by the appropriate
federal, state, local or foreign regulatory authorities necessary to conduct
their respective businesses as described in the SEC Reports, except where the
failure to possess such permits could not, individually or in the aggregate,
have or result in a Material Adverse Effect ("Material Permits"), and neither
the Company nor any Subsidiary has received any notice of proceedings relating
to the revocation or modification of any Material Permit.

                  (m) Title to Assets. The Company and the Subsidiaries have
good and marketable title in fee simple to all real property owned by them that
is material to the business of the Company and the Subsidiaries and owns or has
the right to use all personal property that is material to the business of the
Company and the Subsidiaries, in each case free and clear of all Liens, except
for Liens that do not materially interfere with the use made and proposed to be
made of such property by the Company and the Subsidiaries. Any real property and
facilities held under lease by the Company and the Subsidiaries are held by them
under valid, subsisting and enforceable leases of which the Company and the
Subsidiaries are in compliance.

                  (n) Patents and Trademarks. The Company and the Subsidiaries
have, or have rights to use, all patents, patent applications, trademarks,
trademark applications, service marks, trade names, copyrights, licenses and
other similar rights that are necessary or material for use in connection with
their respective businesses as described in the SEC Reports (collectively, the
"Intellectual Property Rights"). Neither the Company nor any Subsidiary has
received a written notice that the Intellectual Property Rights used by the
Company or any Subsidiary violates or infringes upon the rights of any Person.
To the knowledge of the Company, (i) all such Intellectual Property Rights are
enforceable and (ii) there is no existing infringement by another Person of any
of the Intellectual Property Rights.

                  (o) Insurance. The Company and the Subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary in the businesses in which the
Company and the Subsidiaries are engaged. Neither the Company nor any Subsidiary
has any reason to believe that it will not be able to renew its existing
insurance coverage as and when such coverage expires or to obtain similar
coverage from similar insurers as may be necessary to continue its business
without a significant increase in cost.

                  (p) Transactions With Affiliates and Employees. Except as set
forth in SEC Reports, none of the officers or directors of the Company and, to
the knowledge of the Company, none of the employees of the Company is presently
a party to any transaction with the Company or any Subsidiary (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.





                                       12
<PAGE>

                  (q) Internal Accounting Controls. The Company and the
Subsidiaries maintain a system of internal accounting controls sufficient to
provide reasonable assurance that (i) transactions are executed in accordance
with management's general or specific authorizations, (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain asset
accountability, (iii) access to assets is permitted only in accordance with
management's general or specific authorization, and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

                  (r) Solvency. Based on the financial condition of the Company
as of the Closing Date, (i) the Company's fair saleable value of its assets
exceeds the amount that will be required to be paid on or in respect of the
Company's existing debts and other liabilities (including known contingent
liabilities) as they mature; (ii) the Company's assets do not constitute
unreasonably small capital to carry on its business for the current fiscal year
as now conducted and as proposed to be conducted including its capital needs
taking into account the particular capital requirements of the business
conducted by the Company, and projected capital requirements and capital
availability thereof; and (iii) the current cash flow of the Company, together
with the proceeds the Company would receive, were it to liquidate all of its
assets, after taking into account all anticipated uses of the cash, would be
sufficient to pay all amounts on or in respect of its debt when such amounts are
required to be paid. The Company does not intend to incur debts beyond its
ability to pay such debts as they mature (taking into account the timing and
amounts of cash to be payable on or in respect of its debt).

                  (s) Certain Fees. Except as disclosed in Schedule 3.1(s), no
brokerage or finder's fees or commissions are or will be payable by the Company
to any broker, financial advisor or consultant, finder, placement agent,
investment banker, bank or other Person with respect to the transactions
contemplated by this Agreement.

                  (t) Private Placement. Neither the Company nor any Person
acting on the Company's behalf has sold or offered to sell or solicited any
offer to buy the Securities by means of any form of general solicitation or
advertising. Neither the Company nor any of its Affiliates nor any person acting
on the Company's behalf has, directly or indirectly, at any time within the past
six months, made any offer or sale of any security or solicitation of any offer
to buy any security under circumstances that would (i) eliminate the
availability of the exemption from registration under Regulation D under the
Securities Act in connection with the offer and sale of the Securities as
contemplated hereby (to the extent Regulation D applies thereto) or (ii) cause
the offering of the Securities pursuant to the Transaction Documents to be
integrated with prior offerings by the Company for purposes of any applicable
law, regulation or shareholder approval provisions, including without limitation
under the rules and regulations of any Trading Market. The Company is not, and
is not an Affiliate of, an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

                  (u) Form S-3 Eligibility. The Company is eligible to register
its Common Stock for resale by the holders thereof under Form S-3 promulgated
under the Securities Act.






                                       13
<PAGE>

                  (v) Listing and Maintenance Requirements. The Company has not,
in the two years preceding the date hereof, received notice (written or oral)
from any Trading Market on which the Common Stock is or has been listed or
quoted to the effect that the Company is not in compliance with the listing or
maintenance requirements of such Trading Market. The Company is, and has no
reason to believe that it will not in the foreseeable future continue to be, in
compliance with all such listing and maintenance requirements.

                  (w) Registration Rights. Except as described in Schedule
3.1(w), the Company has not granted or agreed to grant to any Person any rights
(including "piggy-back" registration rights) to have any securities of the
Company registered with the Commission or any other governmental authority that
have not been satisfied.

                  (x) Application of Takeover Protections. The Company and its
Board of Directors have taken all necessary action, if any, in order to render
inapplicable any poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Company's
Certificate of Incorporation (or similar charter documents) or the laws of its
state of incorporation that is or could become applicable to the Purchasers as a
result of the Purchasers and the Company fulfilling their obligations or
exercising their rights under the Transaction Documents, including without
limitation the Company's issuance of the Securities and the Purchasers'
ownership of the Securities.

                  (y) Disclosure. Subject to the issuance of the press release
contemplated by Section 4.8(i), the Company confirms that neither it nor any
other Person acting on its behalf has as of the date of this Agreement provided
any of the Purchasers or their agents or counsel with any information that
constitutes or might constitute material non-public information. The Company
understands and confirms that the Purchasers will rely on the representation
contained in the immediately foregoing sentence in effecting transactions in
securities of the Company. All disclosure provided to the Purchasers regarding
the Company, its business and the transactions contemplated hereby, including
the Schedules to this Agreement, furnished by or on behalf of the Company are
true and correct in all material respects and do not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading. The Company acknowledges and agrees that
no Purchaser makes or has made any representations or warranties with respect to
the transactions contemplated hereby other than those specifically set forth in
Section 3.2.

         3.2      Representations and Warranties of the Purchasers. Each
Purchaser hereby, for itself and for no other Purchaser, represents and warrants
to the Company as follows:

                  (a) Organization; Authority. Such Purchaser is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with the requisite corporate or partnership
power and authority to enter into and to consummate the transactions
contemplated by the Transaction Documents and otherwise to carry out its
obligations thereunder. The purchase by such Purchaser of the Securities
hereunder has been duly authorized by all necessary action on the part of such
Purchaser. Each of this Agreement and the Registration Rights Agreement and the





                                       14
<PAGE>

Voting Agreement has been duly executed by such Purchaser, and when delivered by
such Purchaser in accordance with the terms hereof, will constitute the valid
and legally binding obligation of such Purchaser, enforceable against it in
accordance with its terms.

                  (b) Investment Intent. Such Purchaser is acquiring the
Securities as principal for its own account for investment purposes only and not
with a view to or for distributing or reselling such Securities or any part
thereof, without prejudice, however, to such Purchaser's right, subject to the
provisions of this Agreement and the Registration Rights Agreement, at all times
to sell or otherwise dispose of all or any part of such Securities pursuant to
an effective registration statement under the Securities Act or under an
exemption from such registration and in compliance with applicable federal and
state securities laws. Nothing contained herein shall be deemed a representation
or warranty by such Purchaser to hold Securities for any period of time. Such
Purchaser is acquiring the Securities hereunder in the ordinary course of its
business.

                  (c) Purchaser Status. At the time such Purchaser was offered
the Securities, it was, and at the date hereof it is an "accredited investor" as
defined in Rule 501(a) under the Securities Act.

                  (d) Experience of such Purchaser. Such Purchaser, either alone
or together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment. Such Purchaser is able to
bear the economic risk of an investment in the Securities and, at the present
time, is able to afford a complete loss of such investment.

                  (e) General Solicitation. Such Purchaser is not purchasing the
Securities as a result of any advertisement, article, notice or other
communication regarding the Securities published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar
or any other general solicitation or general advertisement.

                  (f) Reliance. Such Purchaser understands and acknowledges that
(i) the Securities are being offered and sold to it without registration under
the Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (ii) the availability of such exemption
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the foregoing representations and such Purchaser hereby consents to such
reliance.

                  (g) Sale of Securities. Such Purchaser understands that it may
not sell or otherwise dispose of any Securities except pursuant to an effective
registration statement (a "Subject Registration Statement") under the Securities
Act, and (ii) may only sell such Securities in accordance with the Plan of
Distribution set forth in the prospectus forming a part of the Subject
Registration Statement, and otherwise in compliance with the requirements of the
Act, including, but not limited to, the prospectus delivery requirements of the
Act.

                                   ARTICLE IV
                         OTHER AGREEMENTS OF THE PARTIES

         4.1      Transfer Restrictions.

                  (a) Securities may only be disposed of pursuant to an
effective registration statement under the Securities Act, to the Company or
pursuant to an available exemption from or in a transaction not subject to the
registration requirements of the Securities Act, and in compliance with any
applicable state securities laws. In connection with any transfer of Securities
other than pursuant to an effective registration statement or to the Company,
except as otherwise set forth herein, the Company may require the transferor
thereof to provide to the Company an opinion of counsel selected by the
transferor, such counsel and the form and substance of which opinion shall be
reasonably satisfactory to the Company and Company counsel, to the effect that
such transfer does not require registration under the Securities Act.
Notwithstanding the foregoing, the Company hereby consents to and agrees to
register on the books of the Company and with any transfer agent for the
securities of the Company, without any such legal opinion, any transfer of
Securities by a Purchaser to an Affiliate of such Purchaser, provided that the
transferee certifies to the Company that it is an "accredited investor" as
defined in Rule 501(a) under the Securities Act and that it is acquiring the
Securities solely for investment purposes (subject to the qualifications hereof)
and not with a view to, or for, resale, distribution or fractionalization
thereof in whole or in part in violation of the Securities Act. As a condition
of transfer, any such transferee shall agree in writing to be bound by the terms
of this Agreement and shall have the rights of a Purchaser under this Agreement
the Registration Rights Agreement and the Voting Agreement.

                  (b) The Purchasers agree to the imprinting, so long as is
required by this Section 4.1(b), of the following legend on the certificates
evidencing the Securities:

         NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THEY ARE
         CONVERTIBLE/EXERCISABLE HAVE BEEN REGISTERED WITH THE SECURITIES AND
         EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN
         RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT
         OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT
         BE OFFERED OR SOLD IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE SECURITIES ACT UNLESS, IN THE OPINION (WHICH SHALL
         BE IN FORM AND SUBSTANCE SATISFACTORY TO THE CORPORATION) OF COUNSEL
         SATISFACTORY TO THE CORPORATION, SUCH REGISTRATION IS NOT REQUIRED.

The shares of Common Stock issuable upon the conversion of the Shares or the
exercise of the Warrants shall not contain the legend set forth above nor any
other legend while a Conversion Shares Registration Statement is effective under
the Securities Act. On the Conversion Shares Effective Date, the Company shall
issue the letter attached to the Transfer Agent Instructions to the Company's
transfer agent with respect to the shares of Common Stock issuable upon the





                                       16
<PAGE>

conversion of the Shares or the exercise of the Warrants. The shares of Common
Stock issuable upon the conversion of the Notes shall not contain the legend set
forth above nor any other legend while a Note Shares Registration Statement is
effective under the Securities Act. On the Note Shares Effective Date, the
Company shall issue the letter attached to the Transfer Agent Instructions to
the Company's transfer agent with respect to the shares of Common Stock issuable
upon the conversion of the Notes. In addition, none of the Securities (including
the Underlying Shares) shall contain the legend set forth above nor any other
legend (i) following any sale of such Securities pursuant to Rule 144 or (ii) if
such legend is not required under applicable requirements of the Securities Act
(including judicial interpretations and pronouncements issued by the Staff of
the Commission). The Company agrees that at such time as such legend is no
longer required under this Section 4.1(b), it will, no later than four Trading
Days following the delivery by a Purchaser to the Company or the Company's
transfer agent of a certificate representing Securities (including Underlying
Shares) issued with a restrictive legend, deliver or cause to be delivered to
such Purchaser a certificate representing such Securities that is free from all
restrictive and other legends. The Company may not make any notation on its
records or give instructions to any transfer agent of the Company that enlarge
the restrictions on transfer set forth in this Section or in the Registration
Rights Agreement.

                  (c) If the Company fails to deliver or cause to be delivered
to any Purchaser a certificate representing any Securities by the date on which
delivery of such certificate is required by any Transaction Document (the
"Delivery Date"), the Company shall pay to such Purchaser, in cash, as
liquidated damages and not as a penalty, $5,000 for each Trading Day after such
Delivery Date until such certificate is delivered. Nothing herein shall limit
such Purchaser's right to pursue actual damages for the Company's failure to
deliver certificates representing any Securities as required by the Transaction
Documents, and such Purchaser shall have the right to pursue all remedies
available to it at law or in equity including, without limitation, a decree of
specific performance and/or injunctive relief. The exercise of any such rights
shall not prohibit a Purchaser from seeking to enforce damages pursuant to any
other provision of this Agreement or under applicable law.

                  (d) In addition to any other rights available to a Purchaser,
if the Company fails to deliver to such Purchaser a certificate representing
Common Stock by the Delivery Date, and if after such Delivery Date such
Purchaser purchases (in an open market transaction or otherwise) shares of
Common Stock to deliver in satisfaction of a sale by such Purchaser of the
shares that the Purchaser anticipated receiving from the Company (a "Buy-In"),
then the Company shall pay in cash to such Purchaser (in addition to any
remedies available to or elected by the such Purchaser ) the amount by which (x)
such Purchaser's total purchase price (including brokerage commissions, if any)
for the Common Stock so purchased exceeds (y) the product of (1) the lesser of
(A) the aggregate number of shares of Common Stock that such Purchaser
anticipated receiving from the conversion or exercise at issue or (B) the number
of shares of Common Stock so purchased, multiplied by (2) the conversion price
or exercise price, as the case may be, of the Common Stock on the date on which
the applicable notice of conversion or exercise, as the case may be, was given
(the "Notice Date"), in which event the number of shares of Common Stock that
would have been issued had the Company timely complied with its delivery
requirements shall not be so issued. For example, if such Purchaser purchases
Common Stock having a total purchase price of $11,000 to cover a Buy-In in






                                       17

connection with an attempted conversion of Shares with respect to which the
conversion price of an Underlying Share on the applicable Notice Date multiplied
by the number of Underlying Shares was equal to $2,000 under clause (A) of the
immediately preceding sentence, the Company shall be required to pay such
Purchaser $9,000. Such Purchaser shall provide the Company written notice
indicating the amounts payable to the Purchaser in respect of the Buy-In.

         4.2      Acknowledgment of Dilution. The Company acknowledges that the
issuance of the Securities (including the Underlying Shares) will result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions. The Company further acknowledges
that subject to obtaining all required shareholder approvals, if any, its
obligation to issue the Securities (including the Underlying Shares) pursuant to
the Transaction Documents is unconditional and absolute, regardless of the
effect of any such dilution.

         4.3      Furnishing of Information. As long as any Purchaser owns
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to the
Exchange Act. Upon the request of any such Person, the Company shall deliver to
such Person a written certification of a duly authorized officer as to whether
it has complied with the preceding sentence. As long as any Purchaser owns
Securities, if the Company is not required to file reports pursuant to such
laws, it will prepare and furnish to the Purchasers and make publicly available
in accordance with paragraph (c) of Rule 144 such information as is required for
the Purchasers to sell the Securities under Rule 144. The Company further
covenants that it will take such further action as any holder of Securities may
reasonably request, all to the extent required from time to time to enable such
Person to sell such Securities without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144.

         4.4      Integration. Except for the sale of the Securities to the
Purchasers as contemplated herein the Company shall not, and shall use its best
efforts to ensure that no Affiliate of the Company shall, sell, offer for sale
or solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities to the Purchasers, or
that would be integrated with the offer or sale of the Securities for purposes
of the rules and regulations of any Trading Market.

         4.5      Reservation and Listing of Securities.

                  (a) The Company shall maintain a reserve from its duly
authorized shares of Common Stock for issuance pursuant to the Transaction
Documents in such amount as may be required to fulfill its obligations in full
under the Transaction Documents.

                  (b) If, on any date, the number of authorized but unissued
(and otherwise unreserved) shares of Common Stock (the "Remaining Authorized
Shares") is less than 125% of (i) the Actual Minimum on such date, minus (ii)
the number of shares of Common Stock previously issued pursuant to the
Transaction Documents, then the Board of Directors of the Company shall use its
best efforts to amend the Company's certificate or articles of incorporation to




                                       18
<PAGE>

increase the number of authorized but unissued shares of Common Stock to at
least the Required Minimum at such time (minus the number of shares of Common
Stock previously issued pursuant to the Transaction Documents), as soon as
possible and in any event not later than the 65th day after such date; provided
that the Company will not be required at any time to authorize a number of
shares of Common Stock greater than the maximum remaining number of shares of
Common Stock that could possibly be issued after such time pursuant to the
Transaction Documents.

                  (c) If, at the time any Purchaser requests an exercise or
conversion of any Securities, the Actual Minimum minus the number of shares of
Common Stock previously issued pursuant to the Transaction Documents exceeds the
Remaining Authorized Shares, then the Company shall issue to the Purchaser
requesting such exercise or conversion a number of Underlying Shares equal to
such Purchaser's pro-rata portion of the Remaining Authorized Shares (based on
such Purchaser's share of the aggregate purchase price paid hereunder and
considering any Underlying Shares previously issued to such Purchaser), and the
remainder of the Underlying Shares issuable in connection with such exercise or
conversion shall constitute "Excess Shares" pursuant to Section 4.5(g) below.

                  (d) The Company shall (i) in the time and manner required by
each Trading Market, prepare and file with such Trading Market an additional
shares listing application covering a number of shares of Common Stock at least
equal to the greater of (A) the Required Minimum on the Closing Date and (B) the
Required Minimum on the date of such application, (ii) take all steps necessary
to cause such shares of Common Stock to be approved for listing on each Trading
Market as soon as possible thereafter, (iii) provide to the Purchasers evidence
of such listing, and (iv) maintain the listing of such Common Stock on each such
Trading Market or another Eligible Market.

                  (e) If, on any date, the number of shares of Common Stock
previously listed on a Trading Market is less than 125% of the Actual Minimum on
such date, then the Company shall take the necessary actions to list on such
Trading Market, as soon as reasonably possible, a number of shares of Common
Stock at least equal to the Required Minimum on such date; provided that the
Company will not be required at any time to list a number of shares of Common
Stock greater than the maximum number of shares of Common Stock that could
possibly be issued pursuant to the Transaction Documents.

                  (f) If any Trading Market is an Eligible Market, then the
maximum number of shares of Common Stock that the Company may issue pursuant to
the Transaction Documents at an effective purchase price less than the "Market
Value" (as defined in Nasdaq Marketplace Rule 4200(a)(20)) of a share of Common
Stock on the Trading Day immediately preceding the Closing Date (the "Market
Value") equals 3,409,245 shares (the "Issuable Maximum"), unless the Company
obtains shareholder approval in accordance with the rules and regulations of
such Trading Market. If, at the time any Purchaser requests an exercise or
conversion of any Securities, the Actual Minimum (excluding any shares issued or
issuable at an effective purchase price in excess of the Market Value on the
Trading Day immediately preceding the Closing Date) exceeds the Issuable Maximum
(and if the Company has not have previously obtained the required shareholder
approval), then the Company shall issue to the Purchaser requesting such





                                       19
<PAGE>

exercise or conversion a number of Underlying Shares of Common Stock equal to
such Purchaser's pro-rata portion of the Issuable Maximum (based on such
Purchaser's share of the aggregate purchase price paid hereunder and considering
any Underlying Shares previously issued to such Purchaser), and the remainder of
the Underlying Shares issuable in connection with such exercise or conversion
shall constitute "Excess Shares" pursuant to Section 4.5(g) below.

                  (g) Any Purchaser whose receipt of Excess Shares upon exercise
or conversion of Securities is restricted based on the number of Remaining
Authorized Shares or the Issuable Maximum shall have the option, by notice to
the Company, to require the Company to either: (i) use its best efforts to
obtain the required shareholder approval necessary to permit the issuance of
such Excess Shares as soon as is possible, but in any event not later than the
65th day after such notice, or (ii) within five Trading Days after such notice,
pay cash to such Purchaser, as liquidated damages and not as a penalty, in an
amount equal to the number of Excess Shares times the average Closing Price over
the five Trading Days immediately prior to the date of such notice or, if
greater, the five Trading Days immediately prior to the date of payment (the
"Cash Amount"). If the exercising or converting Purchaser elects the first
option under the preceding sentence and the Company fails to obtain the required
shareholder approval on or prior to the 65th day after such notice, then within
three Trading Days after such 65th day, the Company shall pay the Cash Amount to
such Purchaser, as liquidated damages and not as penalty.

         4.6      Conversion and Exercise Procedures. The Transfer Agent
Instructions and Conversion Notice, as defined in the First Certificate of
Designation, the Second Certificate of Designation and the Notes, set forth the
totality of the procedures required to with respect to the conversion of the
Shares and the Notes. The Transfer Agent Instructions and Form of Election to
Purchase under the Warrants set forth the totality of the procedures with
respect to the exercise of the Warrants. No additional legal opinion or other
information or instructions shall be necessary to enable the Purchasers to
convert their Shares and Notes or exercise their Warrants. The Company shall
honor conversions of the Shares and Notes and exercises of the Warrants and
shall deliver Underlying Shares in accordance with the terms, conditions and
time periods set forth in the Transaction Documents.

any option to purchase, or otherwise dispose of (or announce any offer, sale,

Subsidiaries' equity or equity equivalent securities, including without
limitation any debt, preferred stock or other instrument or security that is, at
any time during its life and under any circumstances, convertible into or
exchangeable for Common Stock (any such offer, sale, grant, disposition or
announcement being referred to as a "Subsequent Placement").

                  (b) The Company will not, directly or indirectly, effect any

(the "Subsequent Placement Notice") of its intention to effect such Subsequent

to be raised thereunder, the Person with whom such Subsequent Placement is
proposed to be effected, and attached to which shall be a term sheet or similar

the Company may effect such Subsequent Placement on the terms and to one or more
of the Persons set forth in the Subsequent Placement Notice; provided that the
Company must provide the Purchasers with a second Subsequent Placement Notice,

initial Subsequent Placement Notice with the one or more of the Persons
identified in the Subsequent Placement Notice. If the Purchasers indicate a
willingness to provide financing in excess of the amount set forth in the
Subsequent Placement Notice, then each Purchaser will be entitled to provide
financing pursuant to such Subsequent Placement Notice up to an amount equal to
such Purchaser's pro rata portion of the aggregate purchase price paid for the
Securities under this Agreement, but the Company shall not be required to accept
financing from the Purchasers in an amount in excess of the amount set forth in
the Subsequent Placement Notice.

Related Persons shall have any liability to the Company or any Person asserting
claims on behalf of or in right of the Company in connection with or as a result
of the transactions contemplated by the Transaction Documents, except to the
extent that any losses, claims, damages, liabilities or expenses incurred by the
Company result from the gross negligence or willful misconduct of the applicable
Purchaser or Purchaser Related Person in connection with such transactions. If
the Company breaches its obligations under any Transaction Document, then, in
addition to any other liabilities the Company may have under any Transaction
Document or applicable law, the Company shall pay or reimburse the Purchasers on

jointly, shall indemnify and hold harmless the Company or any Affiliate,
officer, director, controlling person, employee or agent of the Company (a
"Company Related Person") from and against any and all Losses, as incurred,
arising out of or relating to any breach by such Purchaser of any of the
representations, warranties or covenants made by such Purchaser in this
Agreement or any other Transaction Document, or any allegation by a third party
that, if true, would constitute such a breach, excluding only Losses that result
from the Company's or Company Related Person's gross negligence or willful
misconduct. The reimbursement and indemnification obligations of the Purchasers
under this paragraph shall survive any termination of this Agreement until the
End Indemnity Day, and shall be in addition to any liability that such Purchaser
may otherwise have, and shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Company and any
Company Related Persons. If a Purchaser breaches its obligations under any
Transaction Document, then, in addition to any other liabilities such Purchaser
may have under any Transaction Document or applicable law, such Purchaser shall

any such plan or in any way could be deemed to trigger the provisions of such
plan solely by virtue of receiving Securities under the Transaction Documents.

or such other address as may be designated in writing hereafter, in the same
manner, by such Person.

         6.4      Amendments; Waivers. No provision of this Agreement may be
waived or amended except in a written instrument signed, in the case of an
amendment, by the Company and each of the Purchasers or, in the case of a
waiver, by the party against whom enforcement of any such waiver is sought. No
waiver of any default with respect to any provision, condition or requirement of
this Agreement shall be deemed to be a continuing waiver in the future or a
waiver of any subsequent default or a waiver of any other provision, condition
or requirement hereof, nor shall any delay or omission of either party to
exercise any right hereunder in any manner impair the exercise of any such
right.

         6.5      Headings. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

         6.6      Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or obligations




                                       27
<PAGE>

hereunder without the prior written consent of the Purchasers. Any Purchaser may
assign its rights under this Agreement and the Registration Rights Agreement to
any Person to whom such Purchaser assigns or transfers any Securities.

         6.7      No Third-Party Beneficiaries. This Agreement is intended for
the benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person, except that each Purchaser Related Person and each Company
Related Person is an intended third party beneficiary of Section 4.10 and may
enforce the provisions of such Section directly against the Company or the
Purchasers, as the case may be.

         6.8      Governing Law. The corporate laws of the Commonwealth of
Pennsylvania shall govern all issues concerning the relative rights of the
Company and its stockholders. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
and construed and enforced in accordance with the internal laws of the State of
New York, without regard to the principles of conflicts of law thereof. Each
party hereby irrevocably submits to the exclusive jurisdiction of the state and
federal courts sitting in the City of New York, borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein (including with respect to
the enforcement of any of the Transaction Documents), and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof via registered or
certified mail or overnight delivery (with evidence of delivery) to such party
at the address in effect for notices to it under this Agreement and agrees that
such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law.

         6.9      Survival. The representations and warranties set forth in
Article III of this Agreement shall survive the Closing for a period of two
years and the Second Closing for a period of two years. All other
representations, warranties, agreements and covenants contained herein shall
survive the Closing and the delivery, exercise and/or conversion of the
Securities, as applicable until the End Indemnity Day.

         6.10     Execution. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such facsimile signature page
were an original thereof.

         6.11     Severability. If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be




                                       28
<PAGE>

affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.

         6.12     Remedies. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Purchasers and the Company will be entitled to specific performance under the
Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of
obligations described in the foregoing sentence and hereby agrees to waive in
any action for specific performance of any such obligation the defense that a
remedy at law would be adequate.

         6.13     Usury. To the extent it may lawfully do so, the Company hereby
agrees not to insist upon or plead or in any manner whatsoever claim, and will
resist any and all efforts to be compelled to take the benefit or advantage of,
usury laws wherever enacted, now or at any time hereafter in force, in
connection with any claim, action or proceeding that may be brought by any
Purchaser in order to enforce any right or remedy under any Transaction
Document. Notwithstanding any provision to the contrary contained in any
Transaction Document, it is expressly agreed and provided that the total
liability of the Company under the Transaction Documents for payments in the
nature of interest shall not exceed the maximum lawful rate authorized under
applicable law (the "Maximum Rate"), and, without limiting the foregoing, in no
event shall any rate of interest or default interest, or both of them, when
aggregated with any other sums in the nature of interest that the Company may be
obligated to pay under the Transaction Documents exceed such Maximum Rate. It is
agreed that if the maximum contract rate of interest allowed by law and
applicable to the Transaction Documents is increased or decreased by statute or
any official governmental action subsequent to the date hereof, the new maximum
contract rate of interest allowed by law will be the Maximum Rate of interest
applicable to the Transaction Documents from the effective date forward, unless
such application is precluded by applicable law. If under any circumstances
whatsoever, interest in excess of the Maximum Rate is paid by the Company to any
Purchaser with respect to indebtedness evidenced by the Transaction Documents,
such excess shall be applied by such Purchaser to the unpaid principal balance
of any such indebtedness or be refunded to the Company, the manner of handling
such excess to be at such Purchaser's election.

         6.14     Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser under any Transaction Document are several and not
joint with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document. Nothing contained herein or in any
Transaction Document, and no action taken by any Purchaser pursuant thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Purchasers are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Document. Each
Purchaser shall be entitled to independently protect and enforce its rights,
including without limitation the rights arising out of this Agreement or out of
the other Transaction Documents, and it shall not be necessary for any other
Purchaser to be joined as an additional party in any proceeding for such
purpose.
