     SECTION 2.01.  INVESTMENTS. (a) Purchase and Sale of Common Stock. Subject
to the terms and conditions of this Agreement, the Company, at its sole and
exclusive option, may issue and sell to the Investor, and the Investor shall
purchase from the Company shares of the Company's Common Stock, based on such

"Closing") shall be deemed to take place concurrently with the execution and
delivery of this Agreement by the parties hereto and the completion of the
closing transactions set forth in the immediately following sentence. At the

the Investor shall execute and deliver the Registration Rights Agreement; (ii)
the Company shall deliver to the Investor a certificate executed by the
Secretary of the Company, signing in such capacity, dated the date of the
Closing (A) certifying that attached thereto are true and complete copies of the
resolutions duly adopted by the Board of Directors of the Company authorizing
the execution and delivery of the Transaction Documents and the consummation of
the transactions contemplated thereby (including, without limitation, the
reservation and issuance of the Common Stock pursuant to this Agreement), which
authorization shall be in full force and effect on and as of the date of such
certificate and (B) certifying and attesting to the office, incumbency, due
authority and specimen signatures of each Person who executed any Transaction
Document for or on behalf of the Company; (iii) the Company shall deliver to the

L.L.P., counsel to the Company, shall deliver to the Investor an opinion, dated
the date of the Closing and addressed to the Investor, covering customary

hereof by wire transfer to the account designated by the Investor in writing
prior to the Closing.

     SECTION 2.03.  MECHANICS OF DRAW DOWNS. (a) Draw Down Notice. On any
Trading Day during the Commitment Period, the Company may deliver a Draw Down
Notice to the Investor, subject to the satisfaction of the conditions set forth
in Sections 6.02 and 6.03; provided, however, the Investment Amount for each
Draw Down as designated by the Company in the applicable Draw Down Notice shall
be neither less than the Minimum Draw Down Amount nor more than the Maximum Draw
Down Amount (as determined as of the applicable Draw Down Date); provided
further, however, that if the Maximum Draw Down Amount as of


                                       6

<PAGE>   8


the applicable Draw Down Date is less than the Minimum Draw Down Amount, the
Company shall not be entitled to deliver any such Draw Down Notice.

          (b) Delivery of Draw Down Notice. A Draw Down Notice shall be deemed
delivered on (i) the Trading Day that it is received by facsimile or otherwise
(and the Company confirms such delivery by e-mail notice or by telephone
(including voicemail message)) by the Investor if received prior to 12:00 noon,
New York City time such Trading Day, or (ii) in the event it is received by
facsimile or otherwise (and the Company confirms such delivery by e-mail notice
or telephone (including voicemail message)) subsequent to 12:00 noon, New York
City time, on a Trading Day, the immediately succeeding Trading Day. No Draw
Down Notice may be delivered other than on a Trading Day during the Commitment
Period.

          (c) Determination of Draw Down Shares Issuable. Subject to Section
2.03(d) and (e) hereof, the number of Draw Down Shares to be purchased by the
Investor with respect to any Draw Down shall be determined on a daily basis
during the applicable Valuation Period and shall equal with respect to any such
Trading Day the quotient of (x) one-fifth (1/5) of the Investment Amount,
divided by (y) the Purchase Price for such Trading Day. The portion of the
Investment Amount for which Draw Down Shares may be issued for each Trading Day
during the Valuation Period may not exceed one-fifth (1/5) of the Investment
Amount.

          (d) Floor Price Limitation. If the VWAP on any Trading Day during a
Valuation Period is less than the Floor Price specified in the applicable Draw
Down Notice, the Company shall not sell and the Investor shall not purchase the
Draw Down Shares otherwise to be purchased for such Trading Day. In such case,
the Investment Amount shall be reduced by one-fifth (1/5) of the Investment
Amount for each such Trading Day.

          (e) Minimum Trading Hours Limitation. In the event that the Common
Stock is not listed and approved for trading on a Principal Market and free from
any halts or suspensions of trading (whether imposed generally on such Principal
Market or specifically with respect to the Common Stock) for a period of at
least six (6) hours on any Trading Day during a Valuation Period, then the
Company shall not sell and the Investor shall not purchase the Draw Down Shares
otherwise to be purchased in respect of such Trading Day. In such case, the
Investment Amount shall be reduced by one-fifth (1/5) of the Investment Amount
for each such Trading Day.

     SECTION 2.04.  SETTLEMENTS. Subject to the provisions of Section 6.04, on
each Settlement Date the Company shall, unless otherwise instructed by the
Investor, cause the Transfer Agent to electronically transmit shares of Common
Stock to the Investor (by crediting the account of the Investor's Prime Broker,
as designated by the Investor, with The Depository Trust Company through its
Deposit Withdrawal Agent Commission system ("DWAC Transfer")) representing the
Draw Down Shares to be purchased by the Investor on such Settlement Date with
respect to the Draw Down Period immediately preceding such Settlement Date
pursuant to Section 2.03(c) hereof against delivery by the Investor of the
portion of the Investment Amount representing the Draw Down Shares to be
purchased on such Settlement Date by wire transfer of immediately available
funds to an account designated by the Company on or before the Settlement Date.
In addition, on or prior to each such Settlement Date, each of the Company and
the Investor shall deliver all documents, instruments and writings required to
be delivered by


                                       7

<PAGE>   9


either of them pursuant to this Agreement in order to implement and effect the
transactions contemplated herein. The Investor acknowledges that although the
Draw Down shares acquired from the Company pursuant to a DWAC Transfer do not
bear a restrictive legend, they constitute "restricted securities" within the
meaning of the Securities Act and the Investor agrees it will transfer the Draw
Down Shares through the facilities of The Depository Trust Company only pursuant
to the Registration Statement or pursuant to Rule 144 under the Securities Act.

     SECTION 2.05.  DAMAGES FOR LATE DELIVERY OR NON-DELIVERY OF DRAW DOWN
SHARES; INVESTOR RIGHT TO VOID DRAW DOWN NOTICE. (a) In the event the Draw Down
Shares are not delivered by the Company on any Settlement Date, the Company will
pay the Investor, the actual damages, if any, incurred by the Investor as a
result of such late delivery or non-delivery. For purposes of the foregoing, the
actual damages of the Investor shall mean the actual costs, penalties and
interest expense incurred by the Investor resulting from its failure to deliver
on the Settlement Date any Draw Down Shares it was entitled to receive from the
Company on any Settlement Date to any unaffiliated third party to whom it had
agreed to deliver shares of Common Stock. The Investor agrees to act in good
faith to minimize its actual damages in any such event and shall provide the
Company with a detailed calculation of its actual damages and supporting
documentation therefor. Except as provided by Section 2.05(c) below, such amount
may be offset by the Investor against the portion of the Investment Amount
otherwise payable by the Investor with respect to such Draw Down Shares or
future payment obligations of the Investor with respect to subsequent Draw Down
Notices. No amounts shall be payable in the event the Investor does not incur
any actual damages.

          (b) The Company may not deliver a Draw Down Notice in the event (1)
all prior required deliveries of Draw Down Shares have not been made or (2) the
Company has not paid any amounts owed to the Investor pursuant to Section
2.05(a) unless, in connection with such notice, the Company shall have advised
the Investor in writing that the Investor may offset the amounts payable by the
Company (which amount shall be set forth in such notice and shall be consistent
with the Investor's calculation thereof) against the portion of the Investment
Amount otherwise payable by the Investor with respect to such Draw Down Notice.

          (c) In the event the Company, acting in good faith, disputes in
writing the determination by the Investor of the amount of its actual damages
resulting from the failure of the Company to deliver Draw Down Shares on a
Settlement Date (or deliver such Draw Down Shares at all), the Company may
continue to deliver Draw Down Notices for a period of 30 days following such
Settlement Date without paying the Investor such damages, whether in cash or by
offset, provided that the aggregate Investment Amount drawn down during such
30-day period does not exceed $7,500,000. Notwithstanding any payment of damages
by the Company, whether in cash or by offset, if the Company, acting in good
faith, disputes the determination by the Investor of the amount of its actual
damages, such payment shall in no manner constitute an agreement by the Company
with the Investor's calculations. The Company may deliver Draw Down Notices for
up to an additional 90 days from the date of payment (not to extend beyond 120
days from the applicable Settlement Date) while the Company challenges the
Investor's calculations. If the Company and the Investor have not resolved their
dispute by such time as to the amount of actual damages incurred by the
Investor, the ability of the Company to deliver Draw Down Notices shall
thereafter be suspended until such matter is resolved.

the extent described therein, as described in the SEC Reports). The Company and
each of its subsidiaries is duly qualified to transact business and is in good
standing in each jurisdiction in which the character of the properties owned or
leased by it or the nature of its businesses makes such qualification necessary,
except where the failure to so qualify or be in good standing would not have a
material adverse effect on the business, assets, operations, properties,
condition (financial or otherwise) or prospects of the Company and its
subsidiaries, taken as a whole, or any adverse effect on the Company's ability
to consummate the transactions contemplated by, or to execute, deliver and
perform its obligations under, each of the Transaction Documents (a "Material

the Company have been duly and validly authorized and issued, and are fully paid
and nonassessable. The Common Shares (in an amount up to the Maximum Share
Amount) have been duly and validly authorized and have been duly reserved, and
will remain available for issuance, pursuant to this Agreement. When issued
against payment therefor as provided in this Agreement, the Common Shares will
be validly issued, fully paid and nonassessable, free and clear of all
preemptive rights, claims, liens, charges, encumbrances and security interests
of any nature whatsoever. Except as set forth in this Section 3.02 or the SEC
Reports, there are no outstanding options, warrants, conversion rights,
subscription rights, preemptive rights, rights of first refusal or other rights
or agreements of any nature outstanding to subscribe for or to purchase any
shares of Common Stock of the Company or any other securities of the Company of

rights, rights of first refusal or other similar limitation. Except as otherwise
required by law, there are no restrictions upon the voting or transfer of any

each of the Transaction Documents to be executed, delivered or performed by it
and has taken all necessary corporate action to authorize the execution,
delivery and performance by it of, and the consummation of the transactions
contemplated by, the Transaction Documents. No other corporate proceeding on the
part of the Company is necessary, and no consent of any shareholder of the
Company is required, for the valid execution and delivery by the Company of the
Transaction Documents, and the performance and consummation by the Company of
the transactions contemplated by the Transaction Documents to be performed by
the Company. The Company has duly executed and delivered, or concurrently

Assuming the due execution of this Agreement and the Registration Rights
Agreement by the Investor, this Agreement and the Registration Rights Agreement
constitute the valid and binding obligations of the Company, enforceable against
the Company in accordance with each of their respective terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general principles of equity (regardless of
whether enforcement is sought in a proceeding in equity or at law).

     SECTION 3.04.  NO VIOLATION; CONSENTS.

     (a) The execution, delivery and performance by the Company of the
Transaction Documents and the consummation of the transactions contemplated

other liabilities (including any guarantees and other contingent, subordinated,
unmatured or unliquidated liabilities whether or not reduced to judgment,
disputed or undisputed, secured or unsecured), (ii) the Company has sufficient
funds and cash flow to pay its liability on its existing debts as they become
absolute and matured without taking into account future lease payments under
operating leases or payments due after June 30, 2003 under financing leases,
(iii) final judgments against the Company in pending or, to the Company's
knowledge, threatened actions for money damages will not be rendered at a time
when, or in an amount such that, the Company will be unable to satisfy any such
judgments promptly in accordance with their terms (taking into account (a) the
maximum reasonable amount of such judgments in any such actions (other than
amounts that would be remote), (b) the earliest reasonable time at which such
judgments would be rendered and (c) any reasonably expected insurance recovery
with respect thereto), and (iv) the Company does not have unreasonably small

organizational and other governing documents, or any provision of any security
issued by the Company, or of any agreement, instrument or other undertaking to
which the Company is a party or by which it or any of its property or assets is
bound, or the applicable provisions of any law, statute, rule, regulation,
order, writ, injunction, judgment or decree of any court or Governmental
Authority to

                                       11

expected to have a Material Adverse Effect.

     SECTION 3.08.  SEC REPORTS; FINANCIAL CONDITION; NO ADVERSE CHANGES. (a)
The audited consolidated financial statements of the Company and the related
notes thereto as of October 31, 2000 reported on by Ernst & Young LLP,
independent auditors, contained in the SEC Reports, present fairly the
consolidated financial position, results of operations and cash flows of the
Company at such date and for the periods set forth therein . The unaudited
consolidated financial statements of the Company and related notes thereto as of

Company at such date and for the periods set forth therein. The Financial
Statements, including the related schedules and notes thereto, have been
prepared in accordance with generally accepted accounting principles in the
United States as in effect on the date of filing of such documents with the

securities by the Company material in relation to the financial condition of the

          (b) Except as are fully reflected or reserved against in the Financial
Statements and the notes thereto, there are no liabilities or obligations with
respect to the Company or any of its subsidiaries of any nature whatsoever
(whether absolute, accrued, contingent or otherwise and whether or not due)
that, either individually or in the aggregate, after taking into account (a) the
maximum reasonable amount of any liability that may arise on account of any
litigation or any other contingent liability or obligation (other than amounts
that would be remote), (b) the earliest reasonable time at which any such
liability or obligation may become due and (c) any reasonably expected insurance
recovery with respect thereto, could reasonably be expected to have a Material
Adverse Effect.

          (c) Since October 31, 2000, except as set forth in the SEC Reports,
there has been no development or event, nor any prospective development or event
known to the Company or any of its subsidiaries, or any litigation, proceeding
or other action seeking an injunction or other restraining order, damages or
other relief from a court or administrative agency of competent jurisdiction
pending, threatened or, to the knowledge of the Company, contemplated, or any
action of any Governmental Authority, that has had or could reasonably be
expected to have a Material Adverse Effect.

     SECTION 3.09.  USE OF PROCEEDS; FEDERAL REGULATIONS. No part of the net
proceeds from the sale of the Common Stock issued hereunder will be used in a

other than for or in connection with general working capital purposes.

     SECTION 3.10.  SUBSIDIARIES. As of the date hereof, the Company has no
subsidiaries other than those set forth in the SEC Reports or those that conduct
no active business.

Affiliates, nor to its knowledge any Person acting on its or their behalf, has,
directly or indirectly, made any offers or sales of any security or solicited
any offers to buy any security under circumstances that would require
registration under the Securities Act of the offer and sale of the Common Stock
hereunder.

     SECTION 3.12.  NO LITIGATION. Except as disclosed in the SEC Reports, no
litigation or claim (including those for unpaid taxes), or environmental
proceeding against the Company or any of its subsidiaries is pending, threatened
or, to the Company's best knowledge, contemplated that, if determined adversely,
would (after taking into consideration any reasonably expected insurance
recovery with respect thereto) have a Material Adverse Effect on the Company.

     SECTION 3.13.  ENVIRONMENTAL MATTERS. The Company and each of its
subsidiaries is in compliance in all material respects with all applicable state
and federal environmental laws, and no event or condition has occurred that may
interfere in any material respect with the compliance by the Company or any of
its subsidiaries with any environmental law or that may give rise to any
liability under any environmental law that, individually or in the aggregate,
would have a Material Adverse Effect.

     SECTION 3.14.  INTELLECTUAL PROPERTY. The Company (and/or its subsidiaries)
owns or has licenses to use certain patents, copyrights and trademarks
("intellectual property") associated with its business. The Company and its
subsidiaries have all intellectual property rights that are needed to conduct
the business of the Company and its subsidiaries as it is now being conducted as
disclosed in the SEC Reports. To the Company's knowledge, the intellectual
property rights that the Company (and/or its subsidiaries) owns are valid and
enforceable. To the Company's knowledge, the use of such intellectual property
by the Company (and/or its subsidiaries') does not infringe upon or conflict
with any right of any third party, and, except as disclosed in the SEC Reports
neither the Company nor any of its subsidiaries has received notice, written or
otherwise, of any such infringement or conflict other than with respect to
alleged infringements or conflicts that, individually or in the aggregate, if
determined adversely to the Company would not have a Material Adverse Effect.
Except as set forth in the SEC Reports, the Company has no knowledge of any
infringement of its (and/or its subsidiaries) intellectual property by any third
party.

     SECTION 3.15.  INSURANCE. The Company and each of its subsidiaries are
insured by insurers of recognized financial responsibility against such losses
and risks and in such amounts as management of the Company believes to be
prudent. The Company has no reason to believe that it and its subsidiaries will
not be able to renew its existing insurance coverage as and when

                                       13

<PAGE>   15


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.

     SECTION 3.16.  RELATED PARTY TRANSACTIONS. Except as disclosed in the SEC
Reports and except for such transactions for which disclosure pursuant to
Regulation S-K would not be required in an annual report on Form 10-K or
otherwise, none of the officers, directors, employees or 5% or greater
shareholders of the Company is presently a party to any transaction with the
Company or any of its subsidiaries (other than for services as employees,

payments to or from any such officer, director, employee or shareholder or, to
the knowledge of the Company, any corporation, partnership, trust or other

possession of all franchises, grants, authorizations, licenses, permits,
easements, variances, exemptions, consents, certificates, approvals and orders
necessary to own, lease and operate its properties and to carry on its business
as it is now being conducted (collectively, the "Company Permits"), and there is
no action pending or, to the knowledge of the Company, threatened regarding
suspension or cancellation of any of the Company Permits except for such Company
Permits the failure of which to possess, or the cancellation or suspension of
which, would not, individually or in the aggregate, have a Material Adverse
Effect. To the best of its knowledge neither the Company nor any of its
subsidiaries is in material conflict with, or in material default or material
violation of, any of the Company Permits.

     SECTION 3.18.  INTERNAL ACCOUNTING CONTROLS. The Company and each of its
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.

     SECTION 3.19.  TAX RETURNS. The Company has filed or caused to be filed all
Federal tax returns and all material state and local tax returns required to
have been filed by it and has paid or caused to be paid all taxes shown to be
due and payable by it on such returns or on any assessments received by it,

     SECTION 3.20.  DISCLOSURE. The representations and warranties of the
Company in this Agreement and the statements contained in the SEC Reports (at
the time they were filed with the SEC and, except as modified by subsequent SEC
Reports) and the schedules, certificates and exhibits furnished to the Investor
by or on behalf of the Company in connection herewith did not and do not contain
any untrue statement of a material fact and do not omit to state any material
fact necessary to make the statements herein or therein not misleading. The SEC
Reports contain all material information concerning the Company required to be

would not be deliverable in the precise form so delivered if delivered as of
such date during the Valuation Period, then the Company shall cancel the Draw
Down (a "Draw Down Cancellation") immediately by delivering written notice to
the Investor specifying the reasons therefor (the "Draw Down Cancellation

                                       23

<PAGE>   25


Notice"), by facsimile (simultaneously sent by e-mail and with telephonic advice
of the sending (which requirement will be deemed satisfied by leaving of
recorded message)). The Draw Down Cancellation Notice shall be deemed delivered
on (i) the Trading Day it is received by facsimile or otherwise by the Investor

on the last Trading Day of such Valuation Period. Anytime a Draw Down
Cancellation Notice is delivered to the Investor, such Draw Down shall remain
effective as to the portion of the Investment Amount not canceled pursuant to
the preceding sentence.

<PAGE>   26


days after the occurrence of the event that requires such filing, or any such
Registration Statement, after its initial effectiveness, lapses in effect or
sales of all of the Registrable Securities otherwise cannot be made thereunder
(whether by reason of the Company's failure to amend or supplement the

     SECTION 8.01.  NON-DISCLOSURE OF MATERIAL NON-PUBLIC INFORMATION.

     (a) The Company covenants and agrees that it shall refrain from disclosing,
and shall cause its officers, directors, employees and agents to refrain from
disclosing, any material non-public information to the Investor, unless prior to
disclosure of such information the Company identifies such information as being
material non-public information and provides the Investor and its advisors and
representatives with the opportunity to accept or refuse to accept such material
non-public information for review.

     (b) The Company acknowledges and understands that the Investor is entering

non-public information to the Investor or its advisors or representatives, and
the Company represents that it does not disseminate material non-public
information to any investors who purchase stock in the Company in a public
offering, to money managers or to securities analysts; provided, however, that
notwithstanding anything herein to the contrary, the Company will, as
hereinabove provided, immediately notify the Investor and its advisors and
representatives and, if any, underwriters, of the existence of any event or
circumstance (without any obligation to disclose the specific event or
circumstance) of which it becomes aware, constituting material non-public
information (whether or not requested of the Company specifically or generally
during the course of due diligence by such persons or entities), which, if not
disclosed in the prospectus included in the Registration Statement would cause
such prospectus to include a material misstatement or to omit a material fact
required to be stated therein in order to make the statements therein, in light
of the circumstances in which they were made, not misleading.
