following terms, unless the context otherwise requires, have the following
respective meanings:

                  (a) The term "COMPANY" shall include ERF Wireless, Inc. and

         corporation hereunder.

                  (b) The term "COMMON STOCK" includes (a) the Company's common

         without limitation as to amount, either to all or to a share of the
         balance of current dividends and liquidating dividends after the
         payment of dividends and distributions on any shares entitled to
         preference, and the Holders of which shall ordinarily, in the absence
         of contingencies, be entitled to vote for the election of a majority of
         directors of the Company (even though the right so to vote has been
         suspended by the happening of such a contingency) and (c) any other
         securities into which or for which any of the securities described in
         (a) or (b) may be converted or exchanged pursuant to a plan of

         time shall be entitled to receive, or shall have received, on the
         exercise of this Warrant, in lieu of or in addition to Common Stock, or
         that at any time shall be issuable or shall have been issued in
         exchange for or in replacement of Common Stock or Other Securities
         pursuant to Section 4 or otherwise.

         1. EXERCISE OF WARRANT.

                  1.1 METHOD OF EXERCISE.

                  (a) This Warrant may be exercised in whole or in part (but not
         as to a fractional share of Common Stock), at any time and from time to
         time during the Exercise Period by the Holder hereof by delivery of a
         notice of exercise (a "NOTICE OF EXERCISE") substantially in the form
         attached hereto as EXHIBIT A via facsimile to the Company. Promptly
         thereafter the Holder shall surrender this Warrant (if the entire
         amount of the Warrant is subject to the Notice of Exercise) to the
         Company at its principal office via overnight delivery service,
         accompanied by payment of the Purchase Price multiplied by the number
         of shares of Common Stock for which this Warrant is being exercised
         (the "EXERCISE PRICE"). Payment of the Exercise Price shall be made, at
         the option of the Holder, (i) by check or bank draft payable to the
         order of the Company, or (ii) by wire transfer to the account of the
         Company. Upon exercise, the Holder shall be entitled to receive within
         three Trading Days of the Exercise Date (as defined herein), one or
         more certificates, issued in the Holder's name or in such name or names
         as the Holder may direct, subject to the limitations on transfer
         contained herein, for the number of shares of Common Stock so
         purchased. The shares of Common Stock so purchased shall be deemed to
         be issued as of the close of business on the date on which the Company
         shall have received from the Holder payment in full of the Exercise
         Price (the "EXERCISE DATE").

                                       2

                  (b) Upon exercise of a portion of this Warrant in accordance
         with the terms hereof, records showing the amount so exercised and the
         date of exercise shall be maintained on a ledger substantially in the
         form of ANNEX B attached hereto (an originally signed and executed copy
         of which shall be delivered to the Company with each Notice of
         Exercise). The Company shall maintain the originally signed and
         executed ledger and the Holder shall maintain a copy thereof. Upon
         execution of the exercise of the Warrants contemplated by the Notice of
         Exercise, the Company shall deliver to the Holder a copy of ANNEX B
         signed and executed by the Company, and the Holder shall deliver to the
         Company a copy of Annex B signed by the Holder. It is specifically
         contemplated that the Company shall act as the calculation agent for
         all exercises of this Warrant. The Holder and any assignee, by
         acceptance of this Warrant, acknowledges and agrees that, by reason of
         the provisions of this paragraph, following an exercise of a portion of
         this Warrant, the number of shares of Common Stock represented by this
         Warrant will be the amount indicated on ANNEX B attached hereto (which
         may be less than the amount stated on the face hereof).

                  (c) In the event there is a dispute as to the number of shares
         of Common Stock the Holder is entitled to receive upon exercise of this
         Warrant, the Company shall issue to the Holder the number of shares not
         in dispute and the Company and the Holder will use their best efforts
         to resolve such dispute within one Business Day following the receipt
         of a Notice of Exercise. If such dispute cannot be resolved within such
         one-day period, the Company and the Holder shall submit the dispute to
         an independent accountant mutually agreed upon by the Company and the
         Holder to make a final and binding determination of the number of
         shares owed to the Holder. The Company shall issue shares of Common
         Stock owed to Holder as a result of the resolution of the dispute
         within two Business Days following the receipt of the accountant's
         independent determination.

                  1.2 REGULATION D RESTRICTIONS. The Holder hereof represents
and warrants to the Company that it has acquired this Warrant and anticipates
acquiring the shares of Common Stock issuable upon exercise of the Warrant
solely for its own account for investment purposes and not with a view to or for
resale of such securities unless such resale has been registered with the
Commission or an applicable exemption is available therefor and provided that
the Holder shall have furnished to the Company an opinion of counsel in form and
substance reasonably satisfactory to the Company, to the effect that such
transfer is exempt from the registration requirements of the Securities Act and
any applicable state securities laws.

                  1.3 COMPANY ACKNOWLEDGMENT. The Company will, at the time of
the exercise of this Warrant, upon request of the Holder hereof, acknowledge in
writing its continuing obligation to afford to such Holder the registration
rights to which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of a Registration Rights Agreement dated the date
hereof (the "Registration Rights Agreement").

                                       3

<Page>

                  1.4 LIMITATION ON EXERCISE. Notwithstanding the rights of the
Holder to exercise all or a portion of this Warrant as described herein, such
exercise rights shall be limited, solely to the extent set forth in the Purchase
Agreement as if such provisions were specifically set forth herein. In addition,
the number of shares of Common Stock issuable upon exercise of this Warrant is
subject to reduction as specified in Section 10.3 of the Purchase Agreement.

         2. DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. As soon as
practicable after the exercise of this Warrant, and in any event within three
(3) Business Days thereafter, the Company at its expense (including the payment
by it of any applicable issue, stamp or transfer taxes) will cause to be issued
in the name of and delivered to the Holder thereof, or, to the extent
permissible hereunder, to such other person as such Holder may direct, a
certificate or certificates for the number of fully paid and nonassessable
shares of Common Stock (or Other Securities) to which such Holder shall be
entitled on such exercise, plus, in lieu of any fractional share to which such
Holder would otherwise be entitled, cash equal to such fraction multiplied by
the then applicable Purchase Price, together with any other stock or other
securities and property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

         3. ADJUSTMENT FOR EXTRAORDINARY EVENTS. The Purchase Price to be paid
by the Holder upon exercise of this Warrant, and the consideration to be
received upon exercise of this Warrant, shall be adjusted in case at any time or
from time to time pursuant to Article 11 of the Purchase Agreement as if such
provisions were specifically set forth herein.

         4. NO IMPAIRMENT. The Company will not, by amendment of its Certificate
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder of this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of stock
receivable on the exercise of this Warrant above the amount payable therefor on
such exercise, (b) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
unassessable shares of stock on the exercise of this Warrant, and (c) will not
transfer all or substantially all of its properties and assets to any other
person (corporate or otherwise), or consolidate with or merge into any other
person or permit any such person to consolidate with or merge into the Company
(if the Company is not the surviving person), unless such other person shall
expressly assume in writing and will be bound by all the terms of this Warrant.

         5. CERTIFICATE AS TO ADJUSTMENTS. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of this Warrant, the Company will promptly cause its principal
financial officer to compute such adjustment or readjustment in accordance with
the terms of this Warrant and prepare a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (a) the
consideration received or receivable by the Company for any additional shares of

                                       4

<Page>

Common Stock (or Other Securities) issued or sold or deemed to have been issued
or sold, (b) the number of shares of Common Stock (or Other Securities)
outstanding or deemed to be outstanding, and (c) the Purchase Price and the
number of shares of Common Stock to be received upon exercise of this Warrant,
in effect immediately prior to such issue or sale and as adjusted and readjusted
as provided in this Warrant. The Company will forthwith mail a copy of each such
certificate to the Holder of this Warrant, and will, on the written request at
any time of the Holder of this Warrant, furnish to such Holder a like
certificate setting forth the Purchase Price at the time in effect and showing
how it was calculated.

         6. NOTICES OF RECORD DATE, ETC.

                  In the event of

                           (a) any taking by the Company of a record of the
         Holders of any class of securities for the purpose of determining the
         Holders thereof who are entitled to receive any dividend or other
         distribution, or any right to subscribe for, purchase or otherwise
         acquire any shares of stock of any class or any other securities or
         property, or to receive any other right, or

                           (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any transfer of all or substantially all the assets of the
         Company to or consolidation or merger of the Company with or into any
         other Person, or

                           (c) any voluntary or involuntary dissolution,
         liquidation or winding-up of the Company,

then and in each such event the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, and
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any, as of which the Holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares of Common Stock (or Other Securities) for securities or other property
deliverable on such reorganization, reclassification, recapitalization,
transfer, consolidation, merger, dissolution, liquidation or winding-up. Such
notice shall be mailed at least 20 days prior to the date specified in such
notice on which any action is to be taken.

         7. RESERVATION OF STOCK, ETC. ISSUABLE ON EXERCISE OF WARRANT. The
Company will at all times reserve and keep available, solely for issuance and
delivery on the exercise of this Warrant, all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of this Warrant.

by such Holder of any applicable transfer taxes) may direct, calling in the
aggregate on the face or faces thereof for the number of shares of Common Stock
called for on the face of the Warrant so surrendered or for such lesser number
of shares of Common Stock as may be reflected on the Warrant Exercise Ledger
attached as Annex B.

satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of this Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

Holder of this Warrant in the event of any default or threatened default by the
Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that such terms may be

               ARTICLE II. PURCHASE AND SALE OF SECURITIES SECTION

         2.1 PURCHASE AND SALE OF CONVERTIBLE NOTE.

                  (a) Subject to the terms and conditions set forth herein, the
Company agrees to issue and sell to Purchaser, and Purchaser agrees to purchase
from the Company, the Convertible Note.

                  (b) Purchaser shall acquire the Convertible Note on the
Closing Date in an aggregate principal amount of One Million Two Hundred
Eighty-five Thousand Dollars ($1,285,000.00).

                  (c) In connection with the Purchaser's agreement to purchase
the Convertible Note specified in this Article II, the Company shall issue and
deliver to the Purchaser on the Closing Date Warrants to purchase an aggregate
of 300,000 shares of Common Stock.

         SECTION 2.2 PURCHASE PRICE. The purchase price for the Convertible Note
and Warrants on the Closing Date shall be 100% of the principal amount thereof.
Therefore, the aggregate consideration payable by Purchaser to the Company for
the Convertible Note on the Closing Date shall be One Million Two Hundred
Eighty-five Thousand Dollars ($1,285,000.00) (the "Purchase Price").

         SECTION 2.3 CLOSING AND MECHANICS OF PAYMENT.

                  (a) The Purchase Price shall be paid on the Closing Date by
wire transfer of immediately available funds on or before 5:00 p.m. (EST).

                  (b) The Convertible Note and Warrants issued on the Closing

         SECTION 2.4 INTENTIONALLY OMITTED.

                  ARTICLE III. PAYMENT TERMS OF CONVERTIBLE NOTE

         SECTION 3.1 PAYMENT OF PRINCIPAL AND INTEREST; PAYMENT MECHANICS. The
Company will pay all amounts due on each Convertible Note by the method and at
the address specified for such purpose by Purchaser in writing, without the
presentation or surrender of any Convertible Note or the making of any notation
thereon, except that upon written request of the Company made concurrently with
or reasonably promptly after payment or prepayment in full of this Convertible
Note, the holder shall surrender the Convertible Note for cancellation,
reasonably promptly after any such request, to the Company at its principal
executive office. Prior to any sale or other disposition of any Convertible
Note, the holder thereof will, at its election, either endorse thereon the
amount of principal paid thereon and the last date to which interest has been
paid thereon or surrender the Convertible Note to the Company in exchange for a
new Convertible Note or Convertible Notes. The Company will afford the benefits
of this Section 3.1 to any direct or indirect transferee of the Convertible Note

Convertible Note as Purchaser has in this Section 3.1; provided that such
transferee is an "accredited investor" under Rule 501 of the Securities Act.

                                       10

<Page>

         SECTION 3.2 PAYMENT OF INTEREST. Interest shall accrue on the
outstanding principal amount of each Convertible Note as of the date of issuance
and shall be payable as specified therein.

         SECTION 3.3 VOLUNTARY PREPAYMENT. For so long as no Event of Default
shall have occurred and is continuing, the Company may, at its option, repay, in
whole or in part, the Convertible Note, per the terms set forth in Section 4 of
EXHIBIT A hereto, thereof following at least five (5) Business Days prior
written notice to Purchaser (the expiration of such five (5) Business Day period
being referred to as the "prepayment date"); PROVIDED, HOWEVER, that if such
date is not a Business Day, the prepayment date shall be the next Business Day
thereafter.

         SECTION 3.4 MANDATORY PREPAYMENTS (REDEMPTION).

                  (a) Upon (i) the occurrence of a Change in Control of the
Company, (ii) a transfer of all or substantially all of the assets of the
Company to any Person in a single transaction or series of related transactions,
(iii) a consolidation or merger of the Company with or into another Person in
which the Company is not the surviving entity (other than a merger which is
effected solely to change the jurisdiction of incorporation of the Company and
results in a reclassification, conversion or exchange of outstanding shares of
Common Stock solely into shares of Common Stock) (each of items (i), (ii) and
(iii) being referred to as a "Sale Event"), or (iv) the occurrence of a
Registration Default which continues uncured for a period of twenty (20) Trading
Days, then, in each case, the Company shall, upon request of the Majority
Holders, redeem the Convertible Note and Warrants. The redemption price payable
upon any such redemption shall be the redemption price in SECTION 5 of the
Convertible Note and SECTION 13 of the Warrants, respectively (referred to
herein as the "Formula Price").

                  (b) At the option of Purchaser, upon the consummation of one
or more Financings, the Company shall use 10% of the Net Cash Proceeds therefrom
(unless such Net Cash Proceeds from each such Financing is less than $250,000)
to redeem the Convertible Note.

                  (c) Upon the issuance of the Maximum Number of Shares, the
receipt by the Company of Notice of Conversion requiring the issuance of shares
of Common Stock in excess of the Maximum Number of Shares, and the failure
within 40 days of such issuance to obtain shareholder approval to issue
additional shares of Common Stock required to be issued in connection with such
Notices of Conversion (the "Redemption Event"), the Company shall redeem the
outstanding balance of each Convertible Note and Warrant for the Formula Price.

                  (d) In the event that there is an insufficient number of
authorized, issuable, shares of Common Stock registered under the Registration
Statement filed by the Company to allow Purchaser to fully convert the
Convertible Note and exercise all Warrants held by Purchaser and sell such
shares issued thereon, then the Company shall

                                       11

<Page>

immediately file an amendment to the then current Registration Statement to
register a sufficient number of such shares to convert said Convertible Note and
Warrants. Upon the failure within twenty (20) Trading Days measured from the
date of filing the Registration Statement to register a sufficient number of
such shares, the Company shall redeem the outstanding balance of each
Convertible Note and Warrant for the Formula Price. In addition, failure of the
Company to register a sufficient number of such shares to fully convert said
Convertible Note and exercise such Warrants shall be a Registration Default
under SECTION 10.4(E) from the date of the Notice of Conversion to the date of
the earlier of (i) the redemption of the outstanding balance of the Convertible
Note and exercise of all such Warrants or (ii) full conversion of the
Convertible Note and exercise of all such Warrants.

SECTION 3.5 PREPAYMENT PROCEDURES.

         (a) Any permitted prepayment or redemption of the Convertible Note
pursuant to Sections 3.3 or 3.4 above shall be deemed to be effective and
consummated (for purposes of determining the Formula Price and the time at which
Purchaser shall thereafter not be entitled to deliver a Notice of Conversion for
the Convertible Note) as follows:

                  (i) A prepayment pursuant to Section 3.3, the "prepayment
         date" specified therein;

                  (ii) A redemption pursuant to Section 3.4(a), the date of
         consummation of the applicable Sale Event;

                  (iii) A redemption pursuant to Section 3.4(b), three (3)
         Business Days following the date of consummation of the applicable
         Financing (meaning closing and funding); and

                  (iv) A redemption pursuant to Section 3.4(c), the date
         specified in each Convertible Note.

         (b) On the Maturity Date and on the effective date of a repayment or
redemption of the Convertible Note as specified in Section 3.5(a) above, the
Company shall deliver by wire transfer of funds the repayment/redemption price
to Purchaser of the Convertible Note subject to redemption. Should Purchaser not
receive payment of any amounts due on redemption of its Convertible Note by
reason of the Company's failure to make payment at the times prescribed above
for any reason, the Company shall pay to the applicable holder on demand (x)
interest on the sums not paid when due at an annual rate equal to the maximum
lawful rate compounded at the end of each thirty (30) days, until the applicable
holder is paid in full and (y) all costs of collection, including, but not

                                       12

<Page>

limited to, reasonable attorneys' fees and costs, whether or not suit or other
formal proceedings are instituted.

         (c) The Company shall select the Convertible Note to be redeemed in any
redemption in which not all of the Convertible Note are to be redeemed so that
the ratio of the Convertible Note of each holder selected for redemption to the
total Convertible Note owned by that holder shall be the same as the ratio of
all such Convertible Note selected for redemption bears to the total of all then
outstanding Convertible Notes. Should any Convertible Note required to be
redeemed under the terms hereof not be redeemed solely by reason of limitations
imposed by law, the applicable Convertible Note shall be redeemed on the
earliest possible dates thereafter to the maximum extent permitted by law.

         (d) Any Notice of Conversion delivered by Purchaser (including delivery
via telecopy) to the Company prior to the (x) Maturity Date or (y) effective
date of a voluntary repayment pursuant to Section 3.3 or a mandatory prepayment
pursuant to Section 3.4 as specified in Section 3.5(a) above), shall be honored
by the Company and the conversion of the Convertible Note shall be deemed
effected on the Conversion Date. In addition, between the effective date of a
voluntary prepayment pursuant to Section 3.3 or a mandatory prepayment pursuant
to Section 3.4 as specified in Section 3.5(a) above and the date the Company is
required to deliver the redemption proceeds in full to Purchaser, Purchaser may
deliver a Notice of Conversion to the Company. Such notice will be (x) of no
force or effect if the Company timely pays the redemption proceeds to Purchaser
when due or (y) honored on or as of the date of the Notice of Conversion if the
Company fails to timely pay the redemption proceeds to Purchaser when due.

SECTION 3.6 PAYMENT OF ADDITIONAL AMOUNTS.

         (a) Any and all payments by the Company hereunder or under the
Convertible Note to Purchaser and each "qualified assignee" thereof shall be
made free and clear of and without deduction or withholding for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto (all such taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes") unless such Taxes are required by law or the administration thereof
to be deducted or withheld. If the Company shall be required by law or the
administration thereof to deduct or withhold any Taxes from or in respect of any
sum payable under the Convertible Note (i) the holders of the Convertible Note
subject to such Taxes shall have the right, but not the obligation, for a period
of thirty (30) days commencing upon the day it shall have received written
notice from the Company that it is required to withhold Taxes to transfer all or
any portion of the Convertible Note to a qualified assignee to the extent such
transfer can be effected in accordance with the other provisions of this
Agreement and applicable law; (ii) the Company shall make such deductions or
withholdings; (iii) the sum payable shall be increased as may be necessary so
that after making all required deductions or

                                       13

<Page>

withholdings (including deductions or withholdings applicable to additional
amounts paid under this Section 3.6) Purchaser receives an amount equal to the
sum it would have received if no such deduction or withholding had been made;
and (iv) the Company shall forthwith pay the full amount deducted or withheld to
the relevant taxation or other authority in accordance with applicable. A
"qualified assignee" of a Purchaser is a Person that is organized under the laws
of (i) the United States or (II) any jurisdiction other than the United States
or any political subdivision thereof and that (y) represents and warrants to the
Company that payments of the Company to such assignee under the laws in
existence on the date of this Agreement would not be subject to any Taxes and
(z) from time to time, as and when requested by the Company, executes and
delivers to the Company and the Internal Revenue Service forms, and provides the
Company with any information necessary to establish such assignee's continued
exemption from Taxes under applicable law.

         (b) The Company shall forthwith pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies (all such taxes, charges and levies hereinafter referred to as "Other
Taxes") which arise from any payment made under any of the Transaction
Agreements or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement other than Taxes payable solely as a result of the
transfer from Purchaser to a Person of any Security.

         (c) The Company shall indemnify Purchaser, or qualified assignee, for
the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 3.6) paid by Purchaser, or qualified assignee, and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted. Payment under this indemnification shall be made within 30 days from
the date Purchaser or assignee makes written demand therefor. A certificate as
to the amount of such Taxes or Other Taxes submitted to the Company by Purchaser
or assignee shall be conclusive evidence of the amount due from the Company to
such party.

         (d) Within 30 days after the date of any payment of Taxes, the Company
will furnish to Purchaser the original or a certified copy of a receipt
evidencing payment thereof.

         (e) Purchaser shall provide to the Company a form W-8, stating that it
is a non-U.S. person, together with any additional tax forms which may be
required under the Code, as amended after the date hereof, to allow interest
payments to be made to it without deduction.

Company.

                  (d) This Agreement constitutes, and upon execution and

enforceable against the Company in accordance with its respective terms.

                                       15

         SECTION 4.3 CAPITALIZATION. As of the date hereof, the authorized,
issued and outstanding capital stock of the Company is as set forth on SCHEDULE
4.3 hereto and except as set forth on SCHEDULE 4.3 no other shares of capital

stock of the Company are subject to preemptive rights or similar rights of the
stockholders of the Company or any liens or encumbrances imposed through the
actions or failure to act of the Company. Other than as set forth on SCHEDULE
4.3 hereto, as of the date hereof, (i) there are no outstanding options,
warrants, scrip, rights to subscribe for, puts, calls, rights of first refusal,
agreements, understandings, claims or other commitments or rights of any
character whatsoever relating to, or securities or rights convertible into or
exchangeable for any shares of capital stock of the Company or any of its
Subsidiaries, or arrangements by which the Company or any of its Subsidiaries is
or may become bound to issue additional shares of capital stock of the Company
or any of its Subsidiaries, and (ii) there are no agreements or arrangements
under which the Company or any of its Subsidiaries are obligated to register the
sale of any of its or their securities under the Securities Act (except pursuant
to the Registration Rights Agreement) and (iii) there are no anti-dilution or
price adjustment provisions contained in any security issued by the Company (or
in any agreement providing rights to security holders) that will be triggered by
the issuance of the Convertible Note or Conversion Shares. The Company has
furnished to Purchaser true and correct copies of the Company's Corporate
Documents, and the terms of all securities convertible into or exercisable for
Common Stock and the material rights of the holders thereof in respect thereto.

         SECTION 4.4 GOVERNMENTAL AUTHORIZATION. The execution and delivery by
the Company of the Transaction Agreements does not and will not, the issuance
and sale by the Company of the Securities does not and will not, and the
consummation of the transactions contemplated hereby and by the other
Transaction Agreements will not, require any action by or in respect of, or
filing with, any governmental body, agency or governmental official except (a)
such actions or filings that have been undertaken or made prior to the date
hereof and that will be in full force and effect (or as to which all applicable
waiting periods have expired) on and as of the date hereof or which are not
required to be filed on or prior to the Closing Date, (b) such actions or

other stockholders of the Company. Assuming the representations and warranties
of Purchaser herein are true and correct in all material respects, each of the
Securities will have been issued in material compliance with all applicable U.S.
federal and state securities laws. The Company understands and acknowledges
that, in certain circumstances, the issuance of Conversion Shares could dilute
the ownership interests of other stockholders of the Company. The Company

conversion of the Convertible Note is absolute and unconditional regardless of
the dilutive effect that such issuance may have on the ownership interests of
other stockholders of the Company.

         SECTION 4.6 NO CONFLICTS. The execution and delivery by the Company of
the Transaction Agreements to which it is a party did not and will not, the

Corporate Documents, (iii) any agreement, judgment, injunction, order, decree or
other instrument binding upon the Company or any Covered Subsidiary or any of
their respective assets, or result in the creation or imposition of any Lien on
any asset of the Company or any Covered Subsidiary. The Company and each Covered
Subsidiary is in compliance with and conforms to all statutes, laws, ordinances,
rules, regulations, orders, restrictions and all other legal requirements of any
domestic or foreign government or any instrumentality thereof having
jurisdiction over the conduct of its businesses or the ownership of its
properties, except where such failure would not have a Material Adverse Effect.

         SECTION 4.7 FINANCIAL INFORMATION. Since June 30, 2005 (the "Balance
Sheet Date"), except as disclosed in SCHEDULE 4.7, there has been (x) no
material adverse change in the assets or liabilities, or in the business or
condition, financial or otherwise, or in the results of operations or prospects,
of the Company and its Subsidiaries, whether as a result of any legislative or
regulatory change, revocation of any license or rights to do business, fire,
explosion, accident, casualty, labor trouble, flood, drought, riot, storm,
condemnation, act of God, public force or otherwise and (y) no material adverse
change in the assets or liabilities, or in the business or condition, financial
or otherwise, or in the results of operations or prospects, of the Company and
its subsidiaries except in the ordinary course of business; and no fact or
condition exists or is contemplated or threatened which might cause such a
change in the future. The audited consolidated balance sheet of the Company and
its Subsidiaries for the period ending December 31, 2004, and the related
consolidated statements of income, changes in stockholders' equity and changes
in cash flows for the periods then ended, including the footnotes thereto,
except as indicated therein, (i) complied in all material respects with
applicable accounting requirements and (ii) have been prepared in accordance
with GAAP consistently applied throughout the periods indicated. Such financial
statements fairly present the financial condition of the Company and its
Subsidiaries at the dates indicated and the consolidated results of their
operations and cash flows for the periods then ended and, except as indicated
therein, reflect all claims against and all Debts and liabilities of the Company
and its Subsidiaries, fixed or contingent.

         SECTION 4.8 LITIGATION. Except as set forth on SCHEDULE 4.8, there is
no action, suit or proceeding pending or, to the knowledge of the Company,
threatened against the Company or any Covered Subsidiary, before any court or
arbitrator or any governmental body, agency or official in which there is a
reasonable possibility of an adverse decision which could materially adversely
affect the business, condition (financial or otherwise), operations,
performance, properties or prospects of the Company or which challenges the
validity of any Transaction Agreements.

         SECTION 4.9 COMPLIANCE WITH ERISA AND OTHER BENEFIT PLANS.

         (a) Each member of the ERISA Group has fulfilled its obligations under
the minimum funding standards of ERISA and the Code with respect to each Plan
and is in compliance in all material respects with the presently applicable
provisions of ERISA and the Code with respect to each Plan. No member of the
ERISA Group has (i) sought a waiver of the minimum funding standard under
Section 412 of the Code in respect of any Plan, (ii) failed to make any required
contribution or payment to any Plan or Multiemployer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which as resulted or could result in the imposition of a Lien or the posting of
a bond or other security under ERISA or the Code or (iii) incurred any liability
under Title IV of ERISA other than a liability to the PBGC for premiums under
Section 4007 of ERISA.

         (b) The benefit plans not covered under clause (a) above (including
profit sharing, deferred compensation, stock option, employee stock purchase,
bonus, retirement, health or insurance plans, collectively the "Benefit Plans")
relating to the employees of the Company are duly registered where required by,
and are in good standing in all material respects under, all applicable laws.
All required employer and employee contributions and premiums under the Benefit
Plans to the date hereof have been made, the respective fund or funds
established under the Benefit Plans are funded in accordance with applicable
laws, and no past service funding liabilities exist thereunder.

         (c) No Benefit Plans have any unfunded liabilities, either on a "going
concern" or "winding up" basis and determined in accordance with all applicable
laws and actuarial practices and using actuarial assumptions and methods that
are reasonable in the circumstances. No event has occurred and no condition
exists with respect to any Benefit Plans that has resulted or could reasonably
be expected to result in any pension plan having its registration revoked or
wound up (in whole or in part) or refused for the purposes of any applicable
laws or being placed under the administration of any relevant pension benefits
regulatory authority or being required to pay any taxes or penalties (in any
material amounts) under any applicable laws.

         SECTION 4.10 ENVIRONMENTAL MATTERS. The costs and liabilities
associated with Environmental Laws (including the cost of compliance therewith)
are unlikely to have a Material Adverse Effect on the business, condition
(financial or otherwise), operations, performance, properties or prospects of
the Company or any Covered Subsidiary. Each of the Company and the Subsidiaries
conducts its businesses in compliance in all material respects with all
applicable Environmental Laws.

         SECTION 4.11 TAXES. All United States federal, state, county,
municipality, local or foreign income tax returns and all other material tax
returns (including foreign tax returns) which are required to be filed by or on
behalf of the Company and each Covered Subsidiary have been filed and all
material taxes due pursuant to such returns or pursuant to any assessment
received by the Company and each Covered Subsidiary have been paid except those
being disputed in good faith and for which adequate reserves have been
established or would not have a Material Adverse Effect. The charges, accruals
and reserves on the books of the Company and each Covered Subsidiary in respect
of taxes and other governmental charges have been established in accordance with
GAAP.

management, shareholders' or joint venture or similar agreement.

         SECTION 4.13 NOT AN INVESTMENT COMPANY. Neither the Company nor any
Covered Subsidiary is an "Investment Company" within the meaning of Investment
Company Act of 1940, as amended.

         SECTION 4.14 FULL DISCLOSURE. The information heretofore furnished by
the Company to Purchaser for purposes of or in connection with this Agreement or
any transaction contemplated hereby does not, and all such information hereafter
furnished by the Company or any Covered Subsidiary to Purchaser will not (in
each case taken together and on the date as of which such information is
furnished), contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements contained therein, in
the light of the circumstances under which they are made, not misleading.

         SECTION 4.15 NO SOLICITATION; NO INTEGRATION WITH OTHER OFFERINGS. No
form of general solicitation or general advertising was used by the Company or,
to the best of its actual knowledge, any other Person acting on behalf of the
Company, in connection with the offer and sale of the Securities. Neither the
Company, nor, to its knowledge, any Person acting on behalf of the Company, has,
either directly or indirectly, sold or offered for sale to any Person (other
than Purchaser) any of the Securities or, within the six months prior to the
date hereof, any other similar security of the Company except as contemplated by
this Agreement, and the Company represents that neither itself nor any Person
authorized to act on its behalf (except that the Company makes no representation
as to Purchaser and their Affiliates) will sell or offer for sale any such
security to, or solicit any offers to buy any such security from, or otherwise
approach or negotiate in respect thereof with, any Person or Persons so as
thereby to cause the issuance or sale of any of the Securities to be in
violation of any of the provisions of Section 5 of the Securities Act.

         SECTION 4.16 PERMITS. (a) Each of the Company and its Subsidiaries has
all material Permits; (b) all such Permits are in full force and effect, and
each of the Company and its Subsidiaries has fulfilled and performed all
material obligations with respect to such Permits; (c) no event has occurred
which allows, or after notice of lapse of time would allow, revocation or
termination by the issuer thereof or which results in any other material
impairment of the rights of the holder of any such Permit; and (d) the Company
has no reason to believe that any governmental body or agency is considering
limiting, suspending or revoking any such Permit.

         SECTION 4.17 LEASES. Neither the Company nor any Covered Subsidiary is
a party to any capital lease obligation with a value greater than $500,000 or to
any operating lease with an aggregate annual rental greater than $500,000 during
the life of such lease.

         SECTION 4.18 ABSENCE OF ANY UNDISCLOSED LIABILITIES OR CAPITAL CALLS.
There are no liabilities of the Company or any Covered Subsidiary of any kind
whatsoever, whether accrued, contingent, absolute, determined, determinable or
otherwise, and there is no existing condition, situation or set of circumstances
which would reasonably be expected to result in such a liability, other than (i)
those liabilities provided for in the financial statements delivered pursuant to
Section 4.7 and (ii) other undisclosed liabilities which, individually or in the
aggregate, would not have a Material Adverse Effect.

         SECTION 4.19 PUBLIC UTILITY HOLDING COMPANY. Neither the Company nor
any Covered Subsidiary is, or will be upon issuance and sale of the Securities
and the use of the proceeds described herein, subject to regulation under the
Public Utility Holding Company Act of 1935, as amended, the Federal Power Act,
the Interstate Commerce Act or to any federal or state statute or regulation
limiting its ability to issue and perform its obligations under any Transaction
Agreement.

         SECTION 4.20 INTELLECTUAL PROPERTY RIGHTS. Each of the Company and its
Subsidiaries owns, or is licensed under, and has the rights to use, all material
patents, trademarks, trade names, copyrights, technology, know-how and processes
(collectively, "Intellectual Property") used in, or necessary for the conduct of
its business; no claims have been asserted by any Person to the use of any such
Intellectual Property or challenging or questioning the validity or
effectiveness of any license or agreement related thereto. To the best of
Company's and its Subsidiaries' knowledge, there is no valid basis for any such
claim and the use of such Intellectual Property by the Company and its
Subsidiaries will not infringe upon the rights of any Person.

         SECTION 4.21 INSURANCE. The Company and its Subsidiaries maintain, with
financially sound and reputable insurance companies, insurance in at least such
amounts and against such risks such that any uninsured loss would not have a
Material Adverse Effect. All insurance coverages of the Company and its
Subsidiaries are in full force and effect and there are no past due premiums in
respect of any such insurance.

         SECTION 4.22 TITLE TO PROPERTIES. The Company and its Subsidiaries have
good and marketable title to all their respective material properties free and
clear of all Liens except certain newly acquired companies as disclosed on
Schedule 4.22.

         SECTION 4.23 INTERNAL ACCOUNTING CONTROLS. The Company and each of its
Subsidiaries maintain a system of internal accounting controls sufficient, in
the judgment of the Company's Board of Directors, to provide reasonable
assurance that (i) transactions are executed in accordance with managements'
general or specific authorizations, (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with GAAP and to
maintain asset accountability, (iii) access to assets is permitted only in
accordance with management's general or specific authorization, and (iv) the

reasonable intervals and appropriate action is taken with respect to any
differences.

         ARTICLE V. REPRESENTATIONS AND WARRANTIES OF PURCHASER SECTION

         5.1 PURCHASER. Purchaser hereby represents and warrants to the Company
that:

         (a) Purchaser is an "accredited investor" within the meaning of Rule
501(a) under the Securities Act and the Securities to be acquired by it pursuant
to this Agreement are being acquired for its own account and, as of the date
hereof, not with a view toward, or for sale in connection with, any distribution
thereof except in compliance with applicable United States federal and state
securities law; provided that the disposition of Purchaser's property shall at
all times be and remain within its control;

         (b) the execution, delivery and performance of this Agreement and the
purchase of the Securities pursuant thereto are within Purchaser's corporate or
partnership powers, as applicable, and have been duly and validly authorized by
all requisite corporate or partnership action;

         (c) this Agreement has been duly executed and delivered by Purchaser;

         (d) the execution and delivery by Purchaser of the Transaction
Agreements to which it is a party does not, and the consummation of the
transactions contemplated hereby and thereby will not, contravene or constitute
a default under or violation of (i) any provision of applicable law or
regulation, or (ii) any agreement, judgment, injunction, order, decree or other
instrument binding upon Purchaser;

         (e) Purchaser understands that the Securities have not been registered
under the Securities Act and may not be transferred or sold except as specified
in this Agreement or the remaining Transaction Agreements;

         (f) this Agreement constitutes a valid and binding agreement of
Purchaser enforceable in accordance with its terms, subject to (i) applicable
bankruptcy, insolvency or similar laws affecting the enforceability of creditors
rights generally and (ii) equitable principles of general applicability;

         (g) Purchaser has such knowledge and experience in financial and
business matters so as to be capable of evaluating the merits and risks of its
investment in the Securities and Purchaser is capable of bearing the economic
risks of such investment;

                                       21

<Page>

         (h) Purchaser is knowledgeable, sophisticated and experienced in
business and financial matters; Purchaser has previously invested in securities
similar to the Securities and fully understands the limitations on transfer
described herein; Purchaser has been afforded access to information about the
Company and the financial condition, results of operations, property, management
and prospects of the Company sufficient to enable it to evaluate its investment
in the Securities; Purchaser has been afforded the opportunity to ask such
questions as it has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the
offering of the Securities and the merits and the risks of investing in the
Securities; and Purchaser has been afforded the opportunity to obtain such
additional information which the Company possesses or can acquire that is
necessary to verify the accuracy and completeness of the information given to
Purchaser concerning the Company. The foregoing does not in any way relieve the
Company of its representations and other undertakings hereunder, and shall not
limit Purchaser's ability to rely thereon; and

         (i) no part of the source of funds used by Purchaser to acquire the
Securities constitutes assets allocated to any separate account maintained by
Purchaser in which any employee benefit plan (or its related trust) has any
interest.

         (j) Purchaser agrees that for as long as this Securities Purchase
Agreement is in effect or two years, whichever is longer, that Purchaser of any
Affiliate of Purchaser will not short sell (either in a naked or covered short
transaction) any common stock of Company. Any violation of this requirement
would be considered a condition of default by Purchaser and would automatically
void all restrictive covenants of Company imposed by Purchaser and Company.

each Covered Subsidiary to, pay and discharge, at or before maturity, all their
respective material obligations, including, without limitation, tax liabilities,

purchasing or carrying any "margin stock" within the meaning of Regulation G of
the Board of Governors of the Federal Reserve System.

         SECTION 7.9 COMPLIANCE WITH TERMS AND CONDITIONS OF MATERIAL CONTRACTS.
The Company will, and will cause each Covered Subsidiary to, comply, in all
respects, with all terms and conditions of all material contracts to which it is
subject.

         SECTION 7.10 RESERVED SHARES.

         (a) The Company shall at all times have authorized, and reserved for
the purpose of issuance, a sufficient number of shares of Common Stock to
provide for the full conversion of the outstanding Convertible Note and issuance
of the Conversion Shares (based on the conversion price of the Convertible Note
in effect from time to time) (the "Reserved Amount"). The Company shall not
reduce the Reserved Amount without the prior written consent of Purchaser. With
respect to all Securities which contain an indeterminate number of shares of
Common Stock issuable in connection therewith (such as the Convertible Note),
the Company shall include in the Reserve Amount, no less than two (2) times the
number of shares that is then actually issuable upon conversion or exercise of
such Securities. If at any time the number of shares of Common Stock authorized
and reserved for issuance is below the number of Conversion Shares issued or
issuable upon conversion of the Convertible Note, the Company will promptly take
all corporate action necessary to authorize and reserve a sufficient number of
shares, including, without limitation, either (x) calling a special meeting of
shareholders to authorize additional shares, in the case of an insufficient
number of authorized shares or (y) in lieu thereof, consummating the immediate
repurchase of the Convertible Note contemplated in Sections 3.4(c) hereof.

direct the Company's transfer agent to issue certificates, registered in the
name of Purchaser or its nominee, for the Conversion Shares, in such amounts as
specified from time to time by Purchaser to the Company upon proper conversion
of the Convertible Note. Upon conversion of any Convertible Note in accordance
with their terms, the Company will, and will use its best lawful efforts to
cause its transfer agent to, issue one or more certificates representing shares
of Common Stock in such name or names and in such denominations specified by a
Purchaser in a Notice of Conversion. As long as the Registration Statement
contemplated by the Registration Rights Agreement shall remain effective, the
shares of Common Stock issuable upon conversion of any Convertible Note shall be
issued to any transferee of such shares from Purchaser without any restrictive
legend upon appropriate evidence of transfer in compliance with the Securities
Act and the rules and regulations of the Commission, including the prospectus
delivery requirement; provided that for so long as the Registration Statement is
effective, no opinion of counsel will be required to effect any such transfer
unless the transfer agent so requires. In such case the Company will promptly
obtain an Opinion of Counsel to effect such transfer. The Company further
warrants and agrees that no instructions other than these instructions have been
or will be given to its transfer agent. Nothing in this Section 7.11 shall
affect in any way a Purchaser's obligation to comply with all securities laws
applicable to Purchaser upon resale of such shares of Common Stock, including
any prospectus delivery requirements.

         SECTION 7.12 MAINTENANCE OF REPORTING STATUS; SUPPLEMENTAL INFORMATION.
So long as any of the Securities are outstanding, the Company shall timely file
all reports required to be filed with the Commission pursuant to the Exchange
Act. The Company shall not terminate its status as an issuer required to file
reports under the Exchange Act, even if the Exchange Act or the rules and
regulations thereunder would permit such termination. If at anytime the Company
is not subject to the requirements of Section 13 or 15(d) of the Exchange Act,
the Company will promptly furnish at its expense, upon request, for the benefit
of the holders from time to time of Securities, and prospective purchasers of
Securities, information satisfying the information requirements of Rule 144
under the Securities Act.

         SECTION 7.13 FORM D; BLUE SKY LAWS. The Company agrees to file a "Form
D" with respect to the Securities as required under Regulation D of the
Securities Act and to provide a copy thereof to Purchaser promptly after such
filing. The Company shall, on or before the Closing Date, take such action as
the Company shall reasonably determine is necessary to qualify the Securities
for sale to Purchaser at the Closing pursuant to this Agreement under applicable
securities or "blue sky" laws of the states of the United States (or to obtain
an exemption from such qualification), and shall provide evidence of any such
action so taken to Purchaser on or prior to the Closing Date.

                        ARTICLE VIII. NEGATIVE COVENANTS

         The Company hereby agrees that after the date hereof for so long as any
Convertible Note remain outstanding and for the benefit of Purchaser:

         SECTION 8.1 LIMITATIONS ON DEBT OR OTHER LIABILITIES. Neither the
Company nor any Covered Subsidiary will create, incur, assume or suffer to exist
(at any time after the Closing Date, after giving effect to the application of
the proceeds of the issuance of the Securities) (i) any Debt except (x) Debt
incurred in a Permitted Financing, (y) Debt incurred in connection with
equipment leases to which the Company or its Subsidiaries are a party incurred
in the ordinary course of business; and (z) Debt incurred in connection with
trade accounts payable, imbalances and refunds arising in the ordinary course of
business and (ii) any equity securities (including Derivative Securities) (other
than those securities that are issuable (x) under or pursuant to stock option
plans, warrants or other rights programs that exist as of the date hereof, (z)
in connection with the acquisition (including by merger) of a business or of
assets otherwise permitted under this Agreement), unless the Company complies
with the mandatory prepayment terms of Section 3.4(b) hereof.

                                       28

<Page>

         SECTION 8.2 TRANSACTIONS WITH AFFILIATES. The Company and each Covered
Subsidiary will not, directly or indirectly, pay any funds to or for the account
of, make any investment (whether by acquisition or stock or indebtedness, by
loan, advance, transfer of property, guarantee or other agreement to pay,
purchase or service, directly or indirectly, and Debt, or otherwise) in, lease,
sell, transfer or otherwise dispose of any assets, tangible or intangible, to,
or participate in, or effect any transaction in connection with any joint
enterprise or other joint arrangement with, any Affiliate, except, (1) pursuant
to those agreements specifically identified on SCHEDULE 8.2 attached hereto
(with a copy of such agreements annexed to such SCHEDULE 8.2) and (2) on terms
to the Company or such Covered Subsidiary no less favorable than terms that
could be obtained by the Company or such Covered Subsidiary from a Person that
is not an Affiliate of the Company upon negotiation at arms' length, as
determined in good faith by the Board of Directors of the Company; PROVIDED that
no determination of the Board of Directors shall be required with respect to any
such transactions entered into in the ordinary course of business.

         SECTION 8.3 MERGER OR CONSOLIDATION. The Company will not, in a single
transaction or a series of related transactions (i) consolidate with or merge
with or into any other Person, or (ii) permit any other Person to consolidate

or consolidation and (x) immediately before and immediately after given effect
to such transaction (including any indebtedness incurred or anticipated to be
incurred in connection with the transaction), no Default or Event of Default
shall have occurred and be continuing; and (y) the Company has delivered to
Purchaser an Officer's Certificate stating that such consolidation, merger or
transfer complies with this Agreement, and that all conditions precedent in this
Agreement relating to such transaction have been satisfied.

         SECTION 8.4 LIMITATION ON ASSET SALES. Neither the Company nor any
Covered Subsidiary will consummate an Asset Sale of material assets of the
Company or any Covered Subsidiary without the prior written consent of
Purchaser, which consent shall not be unreasonably withheld. As used herein,
"Asset Sale" means any sale, lease, transfer or other disposition (or series of
related sales, leases, transfers or dispositions) or sales of capital stock of a
Covered Subsidiary (other than directors' qualifying shares), property or other
assets (each referred to for the purpose of this definition as a "disposition"),

in the ordinary course of business.

         SECTION 8.5 RESTRICTIONS ON CERTAIN AMENDMENTS. Neither the Company nor
any Covered Subsidiary will waive any provision of, amend, or suffer to be
amended, any provision of such entity's existing Debt, any material contract or

Document if such amendment, in the Company's reasonable judgment, would
materially adversely affect Purchaser or the holders of the Securities without
the prior written consent of Purchaser.

         SECTION 8.6 RESTRICTIONS ON ISSUANCES OF SECURITIES.

         (a) In addition to and not in lieu of the covenant specified in Section
8.1 above:

                  (1) From the Closing Date and continuing until 180 days
         following the date on which the Registration Statement becomes
         effective, the Company agrees that it will not issue any of its equity
         securities (or securities convertible into or exchangeable or
         exercisable for equity securities (the "Derivative Securities")) on
         terms that allow a holder thereof to acquire such equity securities (or
         Derivative Securities) at a discount to the Market Price of the Common
         Stock at the time of issuance or, in the case of Derivative Securities,
         at a conversion price based on any formula (other than standard
         anti-dilution provisions) based on the Market Price on a date later
         than the date of issuance which is below the Market Price on the date
         of issuance (each such event, a "Discounted Equity Offering") other
         than (i) borrowings under conventional credit facilities existing as of
         the date hereof, (ii) stock issued or credit facilities to be
         established in connection with acquisitions, (iii) equity securities or
         Derivative Securities in connection with employee and director
         contracts, stock option and stock purchase plans, (iv) securities
         issued under the Convertible Note or Warrants and (v) private placement
         of restricted securities, not to exceed Seven Million Five Hundred
         Thousand Dollars ($7,500,000.00) in the aggregate from the date hereof,
         that cannot be re-sold into the public market (either under the
         Securities Act of 1933 or contractually) until after a minimum one (1)
         year statutory or contractual hold period. In addition, the Company
         shall not issue any equity securities in connection with a strategic
         alliance entered into by the Company unless such securities are the
         subject of a one year statutory or contractual hold period or, if not
         subject to such a hold period, unless the Purchaser has fully converted
         all outstanding Convertible Note and exercised all Warrants. As used
         herein, "discount" shall include, but not be limited to, (i) any
         warrant, right or other security granted or offered in connection with
         such issuance which, on the applicable date of grant, is offered with
         an exercise or conversion price, as the case may be, at less than the
         then current Market Price of the Common Stock or, if such security has
         an exercise or conversion price based on any formula (other than
         standard anti-dilution provisions) based on the Market Price on a date
         later than the date of issuance, then at a price below the Market Price
         on such date of exercise or conversion, as the case may be, or (ii) any
         commissions, fees or other allowances paid in connection with such
         issuances (other than customary underwriter or placement agent
         commissions, fees or allowances). For the purposes of determining the
         Market Price at which Common Stock is acquired under this Section,
         normal underwriting commissions and placement fees (including
         underwriters' warrants) shall be excluded. Notwithstanding the
         foregoing, the Company may enter into the following types of
         transactions (collectively referred to as "Permitted Financings"): (1)
         "permanent financing" transactions, which would include any form of
         debt or equity financing (other than an underwritten offering), which
         is followed by a reduction of the said financing commitment to zero and
         payment of all related fees and expenses; (2) "project financing" which
         provide for the issuance of recourse debt instruments in connection
         with the operation of the Company's business as presently conducted or
         as proposed to be conducted; (3) an underwritten offering of Common
         Stock, provided that such offering provides for the registration of the
         Conversion Shares if the Registration Statement has not been declared

                                       30

<Page>

         effective; (4) continued funding of the Company under the existing
         Series A preferred debt conversion program as long as any new debt
         conversion funding results in Series A preferred stock that is
         restricted from conversion for at least one year; and (5) other
         financing transactions specifically consented to in writing by the
         Purchaser.

                  (2) The 180-day restrictive period set forth in paragraph (1)
         of this Section 8.6(a) shall be increased by one day for each day a
         Registration Default has occurred and not been cured by the Company.

         (b) Until such time as all of the Convertible Note have been either
redeemed or converted into Conversion Shares in full, the Company agrees it will
not issue any of its equity securities (or Derivative Securities), unless any
shares of Common Stock issued or issuable in connection therewith are
"restricted securities." As used herein "restricted securities" shall mean
securities which may not be sold prior to twelve (12) months following the date
of issuance of such securities by virtue of contractual restrictions imposed by
the Company or otherwise.

         (c) Notwithstanding the foregoing, the restrictions contained in this
Section 8.6 shall not apply to the issuance by the Company of (or the agreement
to issue) Common stock or securities convertible into Common Stock in connection
with (i) the acquisition (including by merger) of a business or of assets
otherwise permitted under this Agreement, or (ii) previously approved Company or
Covered Subsidiary stock option or other compensatory or employee benefit plans.

         SECTION 8.7 LIMITATION ON STOCK REPURCHASES. Except as otherwise set
forth in the Convertible Note and the Warrants, the Company shall not, without
the written consent of the Majority Holders, redeem, repurchase or otherwise
acquire (whether for cash or in exchange for property or other securities or
otherwise) any shares of capital stock of the Company or any warrants, rights or
options to purchase or acquire any such shares.

                                       31

<Page>

         SECTION 8.8 LIMITATION ON SALES BY OFFICERS AND EMPLOYEE DIRECTORS. For
a period of 120 days following the date the Registration Statement is declared
effective by the Commission, no executive officer or a employee director of the
Company shall, individually, sell or otherwise dispose of (other than by reason
of death or disability) to any Person an amount of Common stock greater than
that allowed by Rule 144, promulgated under the Securities Act.

                         ARTICLE IX. RESTRICTIVE LEGENDS

         SECTION 9.1 RESTRICTIONS ON TRANSFER. From and after their respective
dates of issuance, none of the Securities shall be transferable except upon the
conditions specified in this Article IX, which conditions are intended to ensure
compliance with the provisions of the Securities Act in respect of the Transfer
of any of such Securities or any interest therein. Purchaser will use its best
efforts to cause any proposed transferee of any Securities held by it to agree
to take and hold such Securities subject to the provisions and upon the
conditions specified in this Article IX.

         SECTION 9.2 LEGENDS. The Conversion Shares, upon resale by the
Purchaser pursuant to the Registration Statement, shall be freely tradeable and
unrestricted.

         SECTION 9.3 NOTICE OF PROPOSED TRANSFERS. Prior to any proposed
Transfer of the Securities (other than a Transfer (i) registered or exempt from
registration under the Securities Act, (ii) to an affiliate of a Purchaser which
is an "accredited investor" within the meaning of Rule 501(a) under the
Securities Act, provided that any such transferee shall agree to be bound by the
terms of this Agreement and the Registration Rights Agreement, or (iii) to be
made in reliance on Rule 144 under the Securities Act), the holder thereof shall
give written notice to the Company of such holder's intention to effect such
Transfer, setting forth the manner and circumstances of the proposed Transfer,
which shall be accompanied by (a) an opinion of counsel reasonably acceptable to
the Company, confirming that such transfer does not give rise to a violation of
the Securities Act, (B) representation letters in form and substance reasonably
satisfactory to the Company to ensure compliance with the provisions of the
Securities Act and (C) letters in form and substance reasonably satisfactory to
the Company from each such transferee stating such transferee's agreement to be
bound by the terms of this Agreement and the Registration Rights Agreement. Such
proposed Transfer may be effected only if the Company shall have received such
notice of transfer, opinion of counsel, representation letters and other letters
referred to in the immediately preceding sentence, whereupon the holder of such
Securities shall be entitled to Transfer such Securities in accordance with the
terms of the notice delivered by the holder to the Company.

           ARTICLE X. ADDITIONAL AGREEMENTS AMONG THE PARTIES SECTION

         10.1 LIQUIDATED DAMAGES.

                  (a) The Company shall cause its transfer agent to, issue and
deliver shares of Common Stock consistent with Section 7.11 hereof within four
(4) Trading Days of delivery of a Notice of Conversion, as applicable (the
"Deadline") to Purchaser (or any party receiving Securities by transfer from
Purchaser) at the address of Purchaser set forth in the Notice of Conversion.
The Company understands that a delay in the issuance of such certificates after
the Deadline could result in economic loss to Purchaser.

                  (b) Without in any way limiting Purchaser's right to pursue
other remedies, including actual damages and/or equitable relief, the Company
agrees that if delivery of the Conversion Shares is more than one (1) Business
Day after the Deadline (other than a failure due to the circumstances described
in Section 4.3 of the Convertible Note, which failure shall be governed by such
Section) the Company shall pay to Purchaser, as liquidated damages and not as a
penalty, $500 for each $100,000 of Convertible Note then outstanding per day in
cash, for each of the first ten (10) days beyond the Deadline, and $1,000 for
each $100,000 of Convertible Note then outstanding per day in cash for each day
thereafter that the Company fails to deliver such Common Stock. Such cash amount
shall be paid to Purchaser by the last day of the calendar week following the
week in which it has accrued or, at the option of Purchaser (by written notice
to the Company by the first day of the week following the week in which it has
accrued), shall be added to the principal amount of the Convertible Note (if
then outstanding) payable to Purchaser, in which event interest shall accrue
thereon in accordance with the terms of the Convertible Note and such additional
principal amount shall be convertible into Common Stock in accordance with the
terms of the Convertible Note.

         SECTION 10.2 CONVERSION NOTICE. The Company agrees that, in addition to
any other remedies which may be available to Purchaser, including, but not
limited to, the remedies available under Section 10.1, in the event the Company
fails for any reason (other than as a result of actions taken by a Purchaser in
breach of this Agreement) to effect delivery to a Purchaser of certificates with
or without restrictive legends as contemplated by Article IX representing the
shares of Common Stock on or prior to the Deadline after conversion of any
Convertible Note, Purchaser will be entitled, if prior to the delivery of such
certificates, to revoke the Notice of Conversion by delivering a notice to such
effect to the Company whereupon the Company and Purchaser shall each be restored
to their respective positions immediately prior to delivery of such Notice of
Conversion.

         SECTION 10.3 CONVERSION LIMIT. Notwithstanding the conversion rights
under the Convertible Note, unless Purchaser delivers a waiver in accordance
with the immediately following sentence, in no event shall Purchaser be entitled
to convert any portion of the Convertible Note, in excess of that portion of the
Convertible Note, as applicable, of which the sum of (i) the number of shares of
Common Stock beneficially owned by Purchaser and its Affiliates (other than
shares of Common Stock which may be deemed beneficially owned through the
ownership of the unconverted portion of the Convertible Note or other Derivative
Securities convertible into or exchangeable for shares of Common Stock which
contain a limitation similar to that set forth in this Section 10.3), and (ii)
the number of shares of Common Stock issuable upon the conversion of the portion
of the Convertible Note with respect to which this determination is being made,
would result in beneficial ownership by Purchaser and its Affiliates of more
than 4.99% of the outstanding shares of Common Stock. For purposes of Section
10.3(i) beneficial ownership shall be determined in accordance with Rule 13d-3
of the Exchange Act and Regulations 13 D-G thereunder, except as otherwise
provided in this Section 10.3. The foregoing limitation shall not apply and
shall be of no further force or effect (i) immediately preceding and upon the
occurrence of any voluntary or mandatory redemption or repayment transaction
described herein or in the Convertible Note, (ii) immediately preceding and upon
any Sale Event, (iii) on the Maturity Date or (iv) following the occurrence of
any Event of Default which is not cured for a period of ten (10) calendar days.

<Page>

         SECTION 10.4 REGISTRATION RIGHTS.

                  (a) The Company shall grant Purchaser registration rights
covering the Conversion Shares (the "Registrable Securities") on the terms set
forth in the Registration Rights Agreement and herein.

                  (b) The Company shall prepare and file on or before the 90th
day following the Closing Date (the "Filing Date"), a registration statement or
amendment thereto (the "Registration Statement") covering the resale of the
Registrable Securities with the Commission. In the event the Company fails to
file the Registration Statement by the Filing Date for any reason other than
Purchaser's failure to provide information requested by the Company for the
completion and filing of the Registration Statement, the Company shall pay to
Purchaser as liquidated damages (and not as a penalty) one percent (1%) of the
then outstanding principal amount of Convertible Note for each 30-day period,
prorated, until the Registration Statement is filed with the Commission. The
Company shall use its best efforts to cause the Registration Statement to be
declared effective by the Commission or the earlier of (i) 135 days following
the Closing Date, (ii) twenty (20) days following the receipt of a "No Review"
Letter from the Commission or (iii) the first Business Day following the day the
Commission determines the Registration Statement eligible to be declared
effective (the "Required Effectiveness Date"). The Company shall pay all
expenses of registration (other than underwriting fees and discounts, if any, in
respect of Registrable Securities offered and sold under the registration
statement by Purchaser). The Company agrees to file an initial written response
to the Commission within twenty (20) business days of receipt of any comments by
the Commission relating to the Registration Statement. The Company shall provide
to the Purchaser a status letter of the Commission review process addressing the
estimated completion timing of the SEC review, but shall not contain
confidential non-public information which has not been previously disclosed
under Regulation FD or any other applicable regulation.

                  (c) If the Registration Statement is not declared effective by
the Commission by the Required Effectiveness Date, the Company shall pay to
Purchaser, as liquidated damages (and not as a penalty), an amount equal to 2%
of the outstanding principal amount of the Convertible Note, prorated, for each
30 day period the Registration Statement is not declared effective by the
Commission. In the event the Company fails to obtain a valid registration
statement by the 360th day following the Closing Date, the Company will redeem
the Convertible Note and the Warrants as set forth in Section 5 of the
Convertible Note and Section 13 of the Warrants, respectively. Additionally, the
Company will grant to Purchaser certain piggyback registration rights in the
event the Company proposes to effect a registered offering of Common Stock or
warrants or both prior to the filing of the Registration Statement referenced
above.

                                       34

<Page>

                  (d) Any such liquidated damages shall be paid in cash by the
Company to Purchaser by wire transfer in immediately available funds on the last
day of each calendar week following the event requiring its payment.

                  (e) If, following the declaration of effectiveness of the
Registration Statement, such registration statement (or any prospectus or
supplemental prospectus contained therein) shall cease to be effective for any
reason (including but not limited to the occurrence of any event that results in
any prospectus or supplemental prospectus containing an untrue statement of a
material fact or omitting 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 Company fails to file required
amendments to the Registration Statement in order to allow the Purchaser to
resell the Conversion Shares pursuant to the Registration Statement as
unrestricted, unlegended, freely tradeable shares of Common Stock, or if for any
reason there are insufficient shares of such shares of Common Stock registered
under the then current Registration Statement to effect full conversion of the
Convertible Note or exercise of the Warrants (a "Registration Default"), the
Company shall immediately take all necessary steps to cause the Registration
Statement to be amended or supplemented so as to cure such Registration Default.
Failure to cure a Registration Default within ten (10) Business Days shall
result in the Company paying to Purchaser liquidated damages at the rate of one
percent (1%) of the outstanding principal amount of Convertible Note for each 30
day period (prorated), the Registration Default remains uncured.

                      ARTICLE XI. ADJUSTMENT OF FIXED PRICE

         SECTION 11.1 REORGANIZATION. The Conversion Price (the "Fixed Price")
shall be adjusted, as applicable, as hereafter provided.

                                       35

<Page>

         SECTION 11.2 SHARE REORGANIZATION. If and whenever the Company shall:

                  (i) subdivide the outstanding shares of Common Stock into a
         greater number of shares;

                  (ii) consolidate the outstanding shares of Common Stock into a
         smaller number of shares;

                  (iii) issue Common Stock or securities convertible into or
         exchangeable for shares of Common Stock as a stock dividend to all or
         substantially all the holders of Common Stock; or

                  (iv) make a distribution on the outstanding Common Stock to
         all or substantially all the holders of Common Stock payable in Common
         Stock or securities convertible into or exchangeable for Common Stock;
         any of such events being herein called a "Share Reorganization," then
         in each such case the applicable Fixed Price shall be adjusted,
         effective immediately after the record date at which the holders of
         Common Stock are determined for the purposes of the Share
         Reorganization or, if no record date is fixed, the effective date of
         the Share Reorganization, by multiplying the applicable Fixed Price in
         effect on such record or effective date, as the case may be, by a
         fraction of which:

                           (i) the numerator shall be the number of shares of
                  Common Stock outstanding on such record or effective date
                  (without giving effect to the transaction); and

                           (ii) the denominator shall be the number of shares of
                  Common Stock outstanding after giving effect to such Share
                  Reorganization, including, in the case of a distribution of
                  securities convertible into or exchangeable for shares of
                  Common Stock, the number of shares of Common Stock that would
                  have been outstanding if such securities had been converted
                  into or exchanged for Common Stock on such record or effective
                  date.

         SECTION 11.3 RIGHTS OFFERING. If and whenever the Company shall issue
to all or substantially all the holders of Common Stock, rights, options or
warrants under which such holders are entitled, during a period expiring not
more than 45 days after the record date of such issue, to subscribe for or
purchase Common Stock (or Derivative Securities), at a price per share (or, in
the case of securities convertible into or exchangeable for Common Stock, at an
exchange or conversion price per share at the date of issue of such securities)
of less than 95% of the Market Price of the Common Stock on such record date
(any such event being herein called a "Rights Offering"), then in each such case
the applicable Fixed Price shall be adjusted, effective immediately after the
record date at which holders of Common Stock are determined for the purposes of
the Rights Offering, by multiplying the applicable Fixed Price in effect on such
record date by a fraction of which:

                                       36

<Page>

         (i) the numerator shall be the sum of:

                  (i)      the number of shares of Common Stock outstanding on
                           such record date; and

                  (ii)     a number obtained by dividing:

                  (A)      either,

                           (x) the product of the total number of shares of
                  Common Stock so offered for subscription or purchase and the
                  price at which such shares are so offered, or

                           (y) the product of the maximum number of shares of
                  Common Stock into or for which the convertible or exchangeable
                  securities so offered for subscription or

                           (x) purchase may be converted or exchanged and the
                  conversion or exchange price of such securities, or, as the
                  case may be, by

                  (B) the Market Price of the Common Stock on such record date;
         and (ii)the denominator shall be the sum of:

                           (i) the number of shares of Common Stock outstanding
                  on such record date; and

                           (ii) the number of shares of Common Stock so offered
                  for subscription or purchase (or, in the case of Derivative
                  Securities, the maximum number of shares of Common Stock for
                  or into which the securities so offered for subscription or
                  purchase may be converted or exchanged).

To the extent that such rights, options or warrants are not exercised prior to
the expiry time thereof, the applicable Fixed Price shall be readjusted
effective immediately after such expiry time to the applicable Fixed Price which
would then have been in effect upon the number of shares of Common Stock (or
Derivative Securities) actually delivered upon the exercise of such rights,
options or warrants.

                  SECTION 11.4 SPECIAL DISTRIBUTION. If and whenever the Company
shall issue or distribute to all or substantially all the holders of Common
Stock:

                           (i) shares of the Company of any class, other than
                  Common Stock;

                           (ii) rights, options or warrants; or

                           (iii) any other assets (excluding cash dividends and
                  equivalent dividends in shares paid in lieu of cash dividends
                  in the ordinary course);

                                       37

<Page>

and if such issuance or distribution does not constitute a Share Reorganization
or a Rights Offering (any such event being herein called a "Special
Distribution"), then in each such case the applicable Fixed Price shall be
adjusted, effective immediately after the record date at which the holders of
Common Stock are determined for purposes of the Special Distribution, by
multiplying the applicable Fixed Price in effect on such record date by a
fraction of which:

                  (i) the numerator shall be the difference between:

                           (A) the product of the number of shares of Common
                  Stock outstanding on such record date and the Market Price of
                  the Common Stock on such date; and

                           (B) the fair market value, as determined by the
                  Directors (whose determination shall be conclusive), to the
                  holders of Common Stock of the shares, rights, options,
                  warrants, evidences of indebtedness or other assets issued or
                  distributed in the Special Distribution (net of any
                  consideration paid therefor by the holders of Common Stock),
                  and

                  (ii) the denominator shall be the product of the number of
         shares of Common Stock outstanding on such record date and the Market
         Price of the Common Stock on such date.

         SECTION 11.5 CAPITAL REORGANIZATION. If and whenever there shall occur:

                           (i) a reclassification or redesignation of the shares
                  of Common Stock or any change of the shares of Common Stock
                  into other shares, other than in a Share Reorganization;

                           (ii) a consolidation, merger or amalgamation of the
                  Company with, or into another body corporate; or

                           (iii) the transfer of all or substantially all of the
                  assets of the Company to another body corporate;

(any such event being herein called a "Capital Reorganization"), then in each
such case the holder who exercises the right to convert Convertible Note after
the effective date of such Capital Reorganization shall be entitled to receive
and shall accept, upon the exercise of such right, in lieu of the number of
shares of Common Stock to which such holder was theretofore entitled upon the
exercise of the conversion privilege, the aggregate number of shares or other
securities or property of the Company or of the body corporate resulting from
such Capital Reorganization that such holder would have been entitled to receive
as a result of such Capital Reorganization if, on the effective date thereof,
such holders had been the holder of the number of shares of Common Stock to
which such holder was theretofore entitled upon conversion; provided, however,
that no such Capital Reorganization shall be consummated in effect unless all
necessary steps shall have been taken so that such holders shall thereafter be
entitled to receive such number of shares or other securities of the Company or
of the body corporate resulting from such Capital Reorganization, subject to
adjustment thereafter in accordance with provisions the same, as nearly as may
be possible, as those contained above.

         SECTION 11.6 PURCHASE PRICE ADJUSTMENTS. Other than the financing
permitted pursuant to Section 8.6 herein, in case at any time and from time to
time the Company shall issue any shares of Common Stock or Derivative Securities
convertible or exercisable for shares of Common Stock (the number of shares so
issued, or issuable upon conversion or exercise of such Derivative Securities,
as applicable, being referred to as "Additional Shares of Common Stock") for
consideration less than the then Market Price at the date of issuance of such
shares of Common Stock or such Derivative Securities, in each such case the
Conversion Price shall, concurrently with such issuance, be adjusted by
multiplying the Conversion Price immediately prior to such event by a fraction:
(i) the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to the issuance of such Additional Shares of
Common Stock plus the number of shares of Common Stock that the aggregate
consideration received by the Company for the total number of such Additional
Shares of Common Stock so issued would purchase at the Market Price and (ii) the
denominator of which shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of Additional Shares of Common Stock plus the
number of such Additional Shares of Common Stock so issued or sold.

         SECTION 11.7 ADJUSTMENT RULES. The following rules and procedures shall
be applicable to adjustments made in this Article XI:

                  (a) no adjustment in the applicable Fixed Price shall be
required unless such adjustment would result in a change of at least 1% in the
applicable Fixed Price then in effect, provided, however, that any adjustments
which, but for the provisions of this clause would otherwise have been required
to be made, shall be carried forward and taken into account in any subsequent
adjustment;

                  (b) if any event occurs of the type contemplated by the
adjustment provisions of this Article XI but not expressly provided for by such
provisions, the Company will give notice of such event as provided herein, and
the Company's board of directors will make an appropriate adjustment in the
Fixed Price so that the rights of the holders of the applicable Security shall
not be diminished by such event; and

                  (c) if a dispute shall at any time arise with respect to any
adjustment of the applicable Fixed Price, such dispute shall be conclusively
determined by the auditors of the Company or, if they are unable or unwilling to
act, by a firm of independent chartered accountants selected by the Directors
and any such determination shall be binding upon the Company and Purchaser.

                                       39

<Page>

         SECTION 11.8 CERTIFICATE AS TO ADJUSTMENT. The Company shall from time
to time promptly after the occurrence of any event which requires an adjustment
in the applicable Fixed Price deliver to Purchaser a certificate specifying the
nature of the event requiring the adjustment, the amount of the adjustment
necessitated thereby, the applicable Fixed Price after giving effect to such
adjustment and setting forth, in reasonable detail, the method of calculation
and the facts upon which such calculation is based.

         SECTION 11.9 NOTICE TO HOLDERS. If the Company shall fix a record date
for:

                  (a) any Share Reorganization (other than the subdivision of
outstanding Common Stock into a greater number of shares or the consolidation of
outstanding Common Stock into a smaller number of shares),

                  (b) any Rights Offering,

                  (c) any Special Distribution,

                  (d) any Capital Reorganization (other than a reclassification
or redesignation of the Common Stock into other shares),

                  (e) Sale Event; or

                  (f) any cash dividend,

the Company shall, not less than 10 days prior to such record date or, if no
record date is fixed, prior to the effective date of such event, give to
Purchaser notice of the particulars of the proposed event or the extent that
such particulars have been determined at the time of giving the notice.

         SECTION 12.2 POWERS AND REMEDIES CUMULATIVE. No right or remedy herein
conferred upon or reserved to Purchaser is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by
law, be cumulative and in addition to every other right and remedy given
hereunder or now hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy. Every power and remedy given by the Convertible Note or by law
may be exercised from time to time, and as often as shall be deemed expedient,
by Purchaser.

                           ARTICLE XIII. MISCELLANEOUS

                  (a) No failure or delay on the part of any party in exercising
any right, power or remedy hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right, power or remedy preclude
any other or further exercise thereof or the exercise of any other right, power
or remedy.

                  (b) Any provision of this Agreement may be amended,
supplemented or waived if, but only if, such amendment, supplement or waiver is
in writing and is signed by the Company and the Majority Holders; PROVIDED, that
without the consent of each holder of any Convertible Note affected thereby, an
amendment or waiver may not (a) reduce the aggregate principal amount of
Convertible Note whose holders must consent to an amendment or waiver, (b)
reduce the rate or extend the time for payment of interest on any Convertible
Note, (c) reduce the principal amount of or extend the stated maturity of any

<Page>

guarantor of the convertible Note, or by any Person Controlling, Controlled by,
or under common Control with any of the foregoing, shall be disregarded and
deemed not to be outstanding for the purpose of any such determination; and
PROVIDED FURTHER that no such amendment, supplement or waiver which affects the
rights of Purchaser and their affiliates otherwise than solely in their
capacities as holders of Convertible Note shall be effective with respect to
them without their prior written consent.

         SECTION 13.3 INDEMNIFICATION.

                  (a) The Company agrees to indemnify and hold harmless
Purchaser, its Affiliates, and each Person, if any, who controls Purchaser, or
any of its Affiliates, within the meaning of the Securities Act or the Exchange
Act (each, a "Controlling Person"), and the respective partners, agents,
employees, officers and Directors of Purchaser, their Affiliates and any such
Controlling Person (each an "Indemnified Party") and collectively, the
"Indemnified Parties"), from and against any and all losses, claims, damages,
liabilities and expenses (including, without limitation and as incurred,
reasonable costs of investigating, preparing or defending any such claim or
action, whether or not such Indemnified Party is a party thereto, provided that
the Company shall not be obligated to advance such costs to any Indemnified
Party other than Purchaser unless it has received from such Indemnified Party an
undertaking to repay to the Company the costs so advanced if it should be
determined by final judgment of a court of competent jurisdiction that such
Indemnified Party was not entitled to indemnification hereunder with respect to
such costs) which may be incurred by such Indemnified Party in connection with
any investigative, administrative or judicial proceeding brought or threatened
that relates to or arises out of, or is in connection with any activities
contemplated by any Transaction Agreement or any other services rendered in
connection herewith; PROVIDED that the Company will not be responsible for any
claims, liabilities, losses, damages or expenses that are determined by final
judgment of a court of competent jurisdiction to result from such Indemnified
Party's gross negligence, willful misconduct or bad faith.

                  (b) If any action shall be brought against an Indemnified
Party with respect to which indemnity may be sought against the Company under
this Agreement, such Indemnified Party shall promptly notify the Company in
writing and the Company, at its option, may, assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Party and payment of all reasonable fees and expenses. The failure to so notify
the Company shall not affect any obligations the Company may have to such
Indemnified Party under this Agreement or otherwise unless the Company is
materially adversely affected by such failure. Such Indemnified Party shall have
the right to employ separate counsel in such action and participate in the
defense thereof, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party, unless (i) the Company has failed to assume
the defense and employ counsel or (ii) the named parties to any such action
(including any impleaded parties) include such Indemnified Party and the
Company, and such Indemnified Party shall have been advised by counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the Company, in which case, if such
Indemnified Party notifies the Company in writing that it elects to employ
separate counsel at the expense of the Company, the Company shall not have the
right to assume the defense of such action or proceeding on behalf of such
Indemnified Party, PROVIDED, HOWEVER, that the Company shall not, in connection
with any one such action or proceeding or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be responsible hereunder for the
reasonable fees and expenses of more than one such firm of separate counsel, in
addition to any local counsel, which counsel shall be designated by Purchaser.
The Company shall not be liable for any settlement of any such action effected
without the written consent of the Company (which shall not be unreasonably
withheld) and the Company agrees to indemnify and hold harmless each Indemnified
Party from and against any loss or liability by reason of settlement of any
action effected with the consent of the Company. In addition, the Company will

                                       44

<Page>

not, without the prior written consent of Purchaser, settle or compromise or
consent to the entry of any judgment in or otherwise seek to terminate any
pending or threatened action, claim, suit or proceeding in respect to which
indemnification or contribution may be sought hereunder (whether or not any
Indemnified Party is a party thereto) unless such settlement, compromise,
consent or termination includes an express unconditional release of Purchaser
and the other Indemnified Parties, satisfactory in form and substance to
Purchaser, from all liability arising out of such action, claim, suit or
proceeding.

                  (c) If for any reason the foregoing indemnity is unavailable
(otherwise than pursuant to the express terms of such indemnity) to an
Indemnified Party or insufficient to hold an Indemnified Party harmless, then in
lieu of indemnifying such Indemnified Party, the Company shall contribute to the
amount paid or payable by such Indemnified Party as a result of such claims,
liabilities, losses, damages, or expenses (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and by Purchaser on the other from the transactions contemplated by this
Agreement or (ii) if the allocation provided by clause (i) is not permitted
under applicable law, in such proportion as is appropriate to reflect not only
the relative benefits received by the Company on the one hand and Purchaser on
the other, but also the relative fault of the Company and Purchaser as well as
any other relevant equitable considerations. Notwithstanding the provisions of
this Section 13.3, the aggregate contribution of all Indemnified Parties shall
not exceed the amount of interest and fees actually received by Purchaser
pursuant to this Agreement. It is hereby further agreed that the relative
benefits to the Company on the one hand and Purchaser on the other with respect
to the transactions contemplated hereby shall be determined by reference to,
among other things, whether any untrue or alleged untrue statement of material
fact or the omission or alleged omission to state a material fact related to
information supplied by the Company or by Purchaser and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. 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.

                  (d) The indemnification, contribution and expense
reimbursement obligations set forth in this Section 13.3 (i) shall be in
addition to any liability the Company may have to any Indemnified Party at
common law or otherwise; (ii) shall survive the termination of this Agreement
and the other Transaction Agreements and the payment in full of the Convertible
Note and (iii) shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of Purchaser or any other Indemnified
Party.

         SECTION 13.4 EXPENSES: DOCUMENTARY TAXES. The Company has incurred an
application fee equal to 5% of the principal amount of the Convertible Note

Services, Inc. the Purchaser's General Partner. In addition, the Company agrees
to pay to Global Capital Advisors, Ltd., ("GCA") on the Closing Date, a fee
equal to $15,000 (the "Out of Pocket Fee") in full satisfaction of all
obligations of the Company to Purchaser and its agents in connection with the
negotiation and preparation of the Transaction Agreements, relevant due
diligence, and fees and disbursements of legal counsel. The Company has paid
earnest money of $7,500 which shall be applied toward the Out of Pocket Fee at
closing. In addition, the Company agrees to pay any and all stamp, transfer and
other similar taxes, assessments or charges payable in connection with the
execution and delivery of any Transaction Agreement or the issuance of the
Securities to Purchaser, excluding their assigns.

         SECTION 13.5 ADVISOR FEES. Upon Closing of this transaction and the
transaction documents associated with Securities Purchase Agreement between the
Company and certain purchasers dated the date hereof and closed concurrently

addition, on the Closing Date, the Company shall issue to DPS warrants as
described in the Secondary Agreement.

         SECTION 13.6 PAYMENT. The Company agrees that, so long as Purchaser
shall own any Convertible Note purchased by it from the Company hereunder, the
Company will use its best efforts under reasonable business conditions to make
