$5,079,792                                                      January 31, 2002

        FOR VALUE RECEIVED, Alternative Resources Corporation, a Delaware
corporation, (hereinafter called the "COMPANY"), hereby promises to pay in
lawful currency of the United States of America to the order of Wynnchurch
Capital Partners Canada, L.P. or its registered assigns or transferees of all or
any portion hereof (each a "HOLDER") at 150 Field Drive, Suite 165, Lake Forest,
Illinois, 60045, or at such other location as any Holder shall direct as to

<Page>

payment to be received by such Holder, the aggregate principal amount of Five
Million Seventy Nine Thousand Seven Hundred Ninety Two Dollars ($5,079,792.00)
on January 31, 2009 (the "SCHEDULED MATURITY DATE"). This Senior Subordinated
Secured Promissory Note ("NOTE") is issued and delivered by the Company pursuant
to a Securities Purchase Agreement of the Company of even date herewith (the
"SECURITIES PURCHASE AGREEMENT") and the Holder is subject to the terms of and
entitled to the benefits thereunder. Capitalized terms used but not defined
herein shall have the meanings set forth in the Securities Purchase Agreement.
This Note is one of several notes issued by the Company pursuant to the
Securities Purchase Agreement on substantially same terms and conditions set
forth herein (all such notes, including the Note, the "NOTES" and the holders of
the Notes from time to time, including the Holder, the "HOLDERS").

        Subject to the following sentence and the following paragraph, the
unpaid principal amount from time to time outstanding (including any Deferred
Components (as defined herein)) shall bear interest from the date of this Note
at the annual rate of 15% per annum (the "INTEREST RATE"), payable in arrears on
each April 30, July 31, October 31 and January 30 (unless such day is not a
business day, in which event on the next succeeding business day) (each, an
"INTEREST PAYMENT DATE") until payment in full of the principal amount, interest
and all other payment obligations arising hereunder have been fully paid.
Notwithstanding the prior sentence, with respect to interest due on the Notes on
Interest Payment Dates occurring on or prior to January 30, 2006 (the "DEFERRED
INTEREST PAYMENT DATES") the Company may, through written notice delivered to
each of the Holders at least fifteen (15) days prior to such Deferred Interest
Payment Date (which shall set forth the amount of the Deferred Component) and
subject to the following sentence, elect to capitalize up to one-half (1/2) the
amount of any interest payment due on such Deferred Interest Payment Date (the
"DEFERRED COMPONENT") in lieu of payment of the Deferred Component on the
Interest Payment Date, and the Deferred Component shall be deemed additional
principal with respect to this Note. The Company may only elect to take a
Deferred Component so long as (x) there are no past due amounts owed under this
Note and (y) the Company timely pays the entire remaining amount of interest
owed on such Deferred Interest Payment Date.

         Past due amounts (including interest, to the extent permitted by law),
as well as this Note, so long as an Event of Default, (as defined herein) is
continuing, will also accrue interest at the lesser of (a) the Interest Rate
plus 3% per annum and (b) the maximum rate permitted by applicable law ("DEFAULT
INTEREST"), and will be payable on demand. So long as a Directors Violation has
occurred and is continuing, this Note will accrue interest at the Default
Interest rate. Interest on this Note will be calculated on the basis of a
360-day year. All payments under this Note shall be made by wire transfer of
immediately available funds in currency of the United States of America to such
accounts as the Holder shall hereafter give to the Company by written notice
made in accordance with the provisions of this Note.

        All payments hereunder shall, except as required by applicable law, be
made without setoff, deduction or counterclaim, free and clear of all taxes
(other than taxes imposed on the net income of Holder or Holders or franchise
taxes), levies, imports, duties, fees and charges, and without any withholding,
restriction or conditions imposed by any governmental authority. If the Company
is required by law to deduct any such amounts from or in respect of any sum
payable hereunder to Holder, then the sum payable hereunder shall be increased
as may be necessary so

                                     - 2 -
<Page>

that, after making all required deductions, Holder receives an amount equal to
the sum it would have received had no such deductions been made.

        The indebtedness due under the Note is guaranteed and secured by the
Security Agreements (as defined in the Securities Purchase Agreement), subject,
however, to the terms and provisions of the Subordination Agreement.

with respect to such Note, by wire transfer of immediately available funds to an
account or accounts designated by the Holders, on or before the Effective Date
of Prepayment. The Prepayment Notice must be delivered on a business day not
less than ten (10) days (or in the case of a Major Transaction, 30 days) prior
to the date on which such Prepayment is to become effective (the "EFFECTIVE DATE
OF PREPAYMENT") provided, however, that the Effective Date of Prepayment and the
Prepayment may be conditioned upon the closing of a financing transaction, the
closing of a Major Transaction or the approval of the Lender to the Credit

Prepayment Notice) and the Company shall use all reasonable efforts to remove
such conditions by at least two (2) business days prior to the Effective Date of

applied against accrued and unpaid interest (ii) second, applied against unpaid
costs and other obligations arising under this Note and the Security Agreements,
and (iii) third, applied to the principal amount of this Note. Neither the
issuance of a Prepayment Notice nor compliance with Section 1.4 hereof shall
affect a Holder's right to convert the Note in accordance with Article III
hereof.

        1.4  EFFECTIVENESS OF PREPAYMENT. Until the entire outstanding principal
amount of the Notes and all accrued and unpaid interest under the Notes, are
paid with respect to the Notes, the Notes shall be deemed to remain outstanding,

to the Company within forty-five (45) days following the date of the Effective
Date of Prepayment where all or a portion of this Note was Prepaid (other than
with respect to a Prepayment made in connection with a Major Transaction) and
(y) delivery of the Prepayment Amount received by it, have the Prepayment Amount
converted into Note Shares in accordance with Sections 3.3 through 3.7 of this
Note as if Holder had converted such Prepayment Amount of this Note on the
business day before the Effective Date of Prepayment, and the Company shall so
convert this Note, and such conversion shall be deemed to occur one day prior to
such Effective Date of Prepayment.

after a registration statement covering sale of the Note Shares has been filed
provided the Company's transfer agent is participating in the Depository Trust

upon request of a Holder, the Company shall use its reasonable best efforts to
cause its transfer agent to electronically transmit the Common Stock issuable
upon conversion to the Holder by crediting the account of Holder's designated
broker with DTC through its Deposit Withdrawal Agent Commission system.

        3.7  STATUS AS NOTE HOLDER. Upon submission of a Notice of Conversion by
Holder, the principal amount of this Note and the interest thereon covered
thereby shall be deemed converted into shares of Common Stock and the Holder's
rights as a Holder of such converted Note with respect thereto shall cease and
terminate, excepting only the right to receive certificates for such shares of
Common Stock and to any remedies provided herein or otherwise available at law
or in equity to Holder because of a failure by the Company to comply with the

                                     - 7 -
<Page>

terms of this Note. Notwithstanding the foregoing, if Holder has not received
certificates for all shares of Common Stock prior to the fifth (5th) business
day after the expiration of the Delivery Period with respect to a conversion for
any reason, then (unless Holder otherwise elects to retain its status as a
Holder of Common Stock) the Holder shall regain the rights of a holder of a Note
with respect to such unconverted Notes and the Company shall, as soon as
practicable, return such unconverted Notes to the Holder. In all cases, the

if the number of outstanding shares of Common Stock is decreased by a reverse
stock split, combination or reclassification of shares, or other similar event,
the Conversion Price shall be proportionately increased. In such event, the
Company shall notify the Holder of such change on or before the effective date
thereof.

        6.2  ADJUSTMENT DUE TO DISTRIBUTION. If the Company shall declare or
make any distribution of its assets (or rights to acquire its assets) to holders
of any class of Common Stock as a partial liquidating dividend, by way of return
of capital or otherwise (including any dividend or distribution to the Company's
shareholders in cash or shares (or rights to acquire shares) of capital stock of
a subsidiary) (a "DISTRIBUTION") at any time after the date hereof and such
distribution shall be made before the conversion rights of the Holders, and the
Holders will not otherwise be entitled to receive, upon the terms applicable to
such Distribution, the amount of such assets (or rights) which each Holder could
have acquired if such Holder had held the number of shares of Common Stock
acquirable upon complete conversion of this Note immediately before the date on
which a record is taken for determining shareholders entitled to

                                     - 9 -
<Page>

such Distribution, or if no such record is taken, the date as of which the
record holders of Common Stock are to be determined to be entitled to such
Distribution then the Holders shall be entitled, upon the terms applicable to
such Distribution to the amount of such assets or rights upon conversion of this
Note.

        6.3  ANTIDILUTION PROVISIONS. At any time, any amount is outstanding
under this Note, the Conversion Price and the number of Conversion Shares shall
be subject to adjustment from time to time as provided in this Section 6.3. In
the event that any adjustment of the Conversion Price as required herein results
in a fraction of a cent, such Conversion Price shall be rounded up or down to
the nearest cent.

             (a)   ADJUSTMENT OF CONVERSION PRICE AND NUMBER OF SHARES UPON
ISSUANCE OF COMMON STOCK. Except as otherwise provided in Section 6.3(c) and
6.3(e) hereof, if and whenever after the initial issuance of this Note, the
Company issues or sells, or in accordance with Section 6.3(b) hereof is deemed
to have issued or sold, any shares of Common Stock for no consideration or for a
consideration per share less than the Market Price on the date of issuance of
such shares of Common Stock (a "DILUTIVE ISSUANCE"), then effective immediately
upon the Dilutive Issuance, the Conversion Price will be adjusted in accordance
with the following formula:

             E' = (E)(O + (P/M)) / (CSDO)

             where:

             E'    =  the adjusted Conversion Price
             E     =  the then current Conversion Price;
             M     =  the then current Market Price;
             O     =  the number of shares of Common Stock on a fully diluted
                      basis (not including shares of Common Stock held in
                      Treasury of the Company), including shares of Common Stock
                      issuable upon exercise of the Warrants, but excluding
                      Common Stock issuable upon conversion of the Notes,
                      outstanding immediately prior to the Dilutive Issuance;
             P     =  the aggregate consideration,  calculated as set forth in
                      Section 8.3(b) hereof, received by the Company upon such
                      Dilutive Issuance; and
             CSDO  =  the total number of shares of Common Stock
                      Deemed Outstanding (as herein defined)
                      immediately after the Dilutive Issuance.

             (b)   EFFECT ON CONVERSION PRICE OF CERTAIN EVENTS. For purposes of
determining the adjusted Conversion Price under Section 6.3(a) hereof, the
following will be applicable:

                   (i)   ISSUANCE OF RIGHTS OR OPTIONS. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities directly or indirectly exercisable, convertible into or exchangeable
for Common Stock including, without limitation, shares of

                                     - 10 -
<Page>

Common Stock ("CONVERTIBLE SECURITIES") (such warrants, rights and options to
purchase Common Stock or Convertible Securities are hereinafter referred to as
"OPTIONS"), and the price per share for which Common Stock is issuable upon the
exercise of such Options is less than the Market Price on the date of issuance
("BELOW MARKET OPTIONS"), then the maximum total number of shares of Common
Stock issuable upon the exercise of all such Below Market Options (assuming full
exercise, conversion or exchange of Convertible Securities, if applicable) will,
as of the date of the issuance or grant of such Below Market Options, be deemed
to be outstanding and to have been issued and sold by the Company for such price
per share. For purposes of the preceding sentence, the price per share for which
Common Stock is issuable upon the exercise of such Below Market Options is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or granting of such Below Market
Options, plus the minimum aggregate amount of additional consideration, if any,
payable to the Company upon the exercise of all such Below Market Options, plus,
in the case of Convertible Securities issuable upon the exercise of such Below
Market Options, the minimum aggregate amount of additional consideration payable
upon the exercise, conversion or exchange thereof at the time such Convertible
Securities first become exercisable, convertible or exchangeable, by (ii) the
maximum total number of shares of Common Stock issuable upon the exercise of all
such Below Market Options (assuming full conversion of Convertible Securities,
if applicable). No further adjustment to the Conversion Price will be made upon
the actual issuance of such Common Stock upon the exercise of such Below Market
Options or upon the exercise, conversion or exchange of Convertible Securities
issuable upon exercise of such Below Market Options.

                   (ii)  ISSUANCE OF CONVERTIBLE SECURITIES.

                         (A)  If the Company in any manner issues or sells any
Convertible Securities, whether or not immediately convertible (other than where
the same are issuable upon the exercise of Options) and the price per share for
which Common Stock is issuable upon such exercise, conversion or exchange (as
determined pursuant to Section 6.3(b)(ii)(B) if applicable) is less than the
Market Price on the date of issuance, then the maximum total number of shares of
Common Stock issuable upon the exercise, conversion or exchange of all such
Convertible Securities will, as of the date of the issuance of such Convertible
Securities, be deemed to be outstanding and to have been issued and sold by the
Company for such price per share. For the purposes of the preceding sentence,
the price per share for which Common Stock is issuable upon such exercise,
conversion or exchange is determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or sale
of all such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the exercise,
conversion or exchange thereof at the time such Convertible Securities first
become exercisable, convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or
exchange of all such Convertible Securities. No further adjustment to the
Conversion Price will be made upon the actual issuances of such Common Stock
upon exercise, conversion or exchange of such Convertible Securities.

                         (B)  If the Company in any manner issues or sells any
Convertible Securities with a fluctuating conversion or Conversion Price or
exchange ratio (a "VARIABLE RATE CONVERTIBLE SECURITY"), then the price per
share for which Common Stock is

                                     - 11 -
<Page>

issuable upon such exercise, conversion or exchange for purposes of the
calculation contemplated by Section 6.3(b)(ii)(A) shall be deemed to be the
lowest price per share which would be applicable assuming that all holding
periods and other conditions to any discounts contained in such Convertible
Security have been satisfied.

                   (iii) CHANGE IN OPTION PRICE OR CONVERSION RATE. If there is
a change at any time in (i) the amount of additional consideration payable to
the Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange or any Convertible Securities; or (iii) the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock
(other than under or by reason of provisions designed to protect against
dilution), the Conversion Price in effect at the time of such change will be
readjusted to the Conversion Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold.

                   (iv)  TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED
CONVERTIBLE SECURITIES. If, in any case, the total number of shares of Common
Stock issuable upon exercise of any Options or upon exercise, conversion or
exchange of any Convertible Securities is not, in fact, issued and the rights to
exercise such option or to exercise, convert or exchange such Convertible
Securities shall have expired or terminated, the Conversion Price then in effect
will be readjusted to the Conversion Price which would have been in effect at
the time of such expiration or termination had such Options or Convertible
Securities, to the extent outstanding immediately prior to such expiration or
termination (other than in respect of the actual number of shares of Common
Stock issued upon exercise or conversion thereof), never been issued.

                   (v)   CALCULATION OF CONSIDERATION RECEIVED. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Note will be the amount
received by the Company therefor, before deduction of reasonable commissions,
underwriting discounts or allowances or other reasonable expenses paid or
incurred by the Company in connection with such issuance, grant or sale, plus
the minimum aggregate amount of additional consideration, if any, payable to the
Company upon the exercise, conversion or exchange of all such Options or
Convertible Securities at the time such Options or Convertible Securities first
become exercisable, convertible or exchangeable. In case any Common Stock,
Options or Convertible Securities are issued or sold for a consideration part or
all of which shall be other than cash, the amount of the consideration other
than cash received by the Company will be the fair market value of such
consideration except where such consideration consists of freely-tradeable
securities, in which case the amount of consideration received by the Company
will be the Market Price thereof as of the date of receipt. In case any Common
Stock, Options or Convertible Securities are issued in connection with any
merger or consolidation in which the Company is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair market value of
such portion of the net assets and business of the non-surviving corporation as
is attributable to such Common Stock, Options or Convertible Securities, as the
case may be. The fair market value of any consideration other than cash or
securities will be determined in the good faith reasonable business judgment of
the Board of Directors, provided, however, that in any case where the

                                     - 12 -
<Page>

aggregate value of such consideration exceeds Five Million Dollars ($5,000,000)
such valuation is subject to the reasonable approval of the Majority Holders. If
the Company and the Majority Holders are unable to agree upon the valuation set
forth in the prior sentence, the valuation will be determined by an independent,
nationally recognized accounting form selected by the Company and reasonably
acceptable to the Majority Holders, the costs of which will be borne by the
Company.

                   (vi)  EXCEPTIONS TO ADJUSTMENT OF CONVERSION PRICE. No
adjustment to the Conversion Price will be made (i) upon the exercise of any
warrants, options or convertible securities issued and outstanding on the date
hereof in accordance with the terms of such securities as of such date; (ii)
upon the issuance of Notes in accordance with terms of the Securities Purchase
Agreement; or (iii) upon the exercise of the Notes.

             (c)   ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the
Conversion Price pursuant to the provisions of this Section 6.3, the number of
shares of Common Stock issuable upon exercise of this Note shall be adjusted by
multiplying a number equal to the Conversion Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable upon
exercise of this Note immediately prior to such adjustment and dividing the
product so obtained by the adjusted Conversion Price.

             (d)   MAJOR TRANSACTIONS. If the Company shall consolidate or merge
with any other corporation or entity (other than a merger in which the Company
is the surviving or continuing entity and its capital stock is unchanged and
unissued in such transaction and which does not result in a Change of Control
(as defined in this Note)) or there shall occur any share exchange pursuant to
which all of the outstanding shares of Common Stock are converted into other
securities or property or any reclassification or change of the outstanding
shares of Common Stock or the Company shall sell all or substantially all of its
assets (each of the foregoing being a "MAJOR TRANSACTION"), then the holder of
this Note may, at its option, either (a) in the event that the Common Stock
remains outstanding or holders of Common Stock receive any common stock or a
substantially similar equity interest, retain this Note and this Note shall
continue to apply to such Common Stock or shall apply, as nearly as practicable,
to such other common stock or equity interest, as the case may be (with such
equitable adjustments to the Conversion Price as may be required), or (b)
regardless of whether (a) applies, receive consideration, in exchange for this
Note, the number of shares of stock or securities or property of the Company, or
of the entity resulting from such Major Transaction (the "MAJOR TRANSACTION
CONSIDERATION"), to which a holder of the number of shares of Common Stock
delivered upon the conversion of this Note would have been entitled upon such
Major Transaction had such holder so exercised this Note (without regard to any
limitations on exercise herein or elsewhere contained) on the trading date
immediately preceding the public announcement of the transaction resulting in
such Major Transaction and had such Common Stock been issued and outstanding and
had such Holder been the holder of record of such Common Stock at the time of
the consummation of such Major Transaction, and the Company shall make lawful
provision for the foregoing as a part of such Major Transaction and, to the
extent the replacements for the Note Shares are not able to be sold immediately
and in full by Holder without registration of such shares under the Securities
Act, shall cause the issuer of any security in such transaction which
constitutes "Registrable Securities" under the Registration Rights Agreement to
assume all of the Company's obligations under the Registration Rights Agreement.
No later than ten (10) days

                                     - 13 -
<Page>

prior to the consummation of the Major Transaction, but not prior to the public
announcement of such Major Transaction, the Company shall deliver written notice
("NOTICE OF TRANSACTION") to each holder of a Note, which Notice of Transaction
shall be deemed to have been delivered one (1) business day after the Company's
sending such notice by telecopy (provided that the Company sends a confirming
copy of such notice on the same day by overnight courier) of such Notice of
Transaction. Such Notice of Transaction shall indicate the amount and type of
the transaction consideration which such holder of a Note would receive under
this section ("TRANSACTION CONSIDERATION"). If the Transaction Consideration is
cash and does not consist entirely of United States currency, such holder may
elect to receive United States currency in an amount equal to the value of the
Transaction Consideration in lieu of the Transaction Consideration by delivering
notice of such election to the Company within ten (10) days of such holder's
receipt of the Notice of Transaction which notice shall also set forth whether
Holder chooses to avail itself of any of the options under this Section 6.3(d)
(and, if so, which section).

             (e)   MINIMUM ADJUSTMENT OF CONVERSION PRICE. No adjustment of the
Conversion Price shall be made in an amount of less than 1% of the Conversion
Price in effect at the time such adjustment is otherwise required to be made,
but any such lesser adjustment shall be carried forward and shall be made at the
time and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Conversion Price. Other than pursuant to Sections 6(b)(iii) and 6(b)(iv) hereof,
no adjustment under 6.3(a) shall have the effect of increasing the Conversion
Price.

             (f)   OTHER NOTICES. In case at any time:

                   (i)   the Company shall declare any dividend upon the Common
        Stock payable in shares of stock of any class or make any other
        distribution to the holders of the Common Stock;

                   (ii)  the Company shall offer for subscription pro rata to
        the holders of the Common Stock any additional shares of stock of any
        class or other rights;

                   (iii) there shall be any capital reorganization of the
        Company, or reclassification of the Common Stock, or consolidation or
        merger of the Company with or into, or sale of all or substantially all
        of its assets to, another corporation or entity; or

                   (iv)  there shall be a voluntary or involuntary dissolution,
        liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder (x) notice of the
date on which the books of the Company shall close or a record shall be taken
for determining the holders of Common Stock entitled to receive any such
dividend, distribution, or subscription rights or for determining the holders of
Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (y) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive such dividend,
distribution, or

                                     - 14 -
<Page>

subscription rights or to exchange their Common Stock for stock
or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such notice shall be given at least 30 days
prior to the record date or the date on which the Company's books are closed in
respect thereto, but in no event earlier than public announcement of such
proposed transaction or event.

             (g)   CERTAIN DEFINITIONS.

                   (i)   "COMMON STOCK DEEMED OUTSTANDING" shall mean the number
        of shares of Common Stock on a fully diluted basis (not including shares
        of Common Stock held in Treasury of the Company), including shares of
        Common Stock issuable upon exercise of the Warrants, but excluding
        Common Stock issuable upon conversion of the Notes, plus (x) in case of
        any adjustment required by Section 6.3(a) resulting from the issuance of
        any Options, the maximum total number of shares of Common Stock issuable
        upon the exercise of the Options for which the adjustment is required
        (including any Common Stock issuable upon the conversion of Convertible
        Securities issuable upon the exercise of such Options), and (y) in the
        case of any adjustment required by Section 6.3(a) resulting from the
        issuance of any Convertible Securities, the maximum total number of
        shares of Common Stock issuable upon the exercise, conversion or
        exchange of the Convertible Securities for which the adjustment is
        required, as of the date of issuance of such Convertible Securities, if
        any.

                   (ii)  "COMMON STOCK," for purposes of this Article VI,
        includes the Common Stock and any additional class of stock of the
        Company having no preference as to dividends or distributions on
        liquidation, provided that the shares purchasable pursuant to this Note
        shall include only Common Stock in respect of which this Note is
        convertible, or shares resulting from any subdivision or combination of
        such Common Stock, or in the case of any reorganization,
        reclassification, consolidation, merger, or sale of the character
        referred to in Section 8.3(e) hereof, the stock or other securities or
        property provided for in such Section.

        6.4  PURCHASE RIGHTS. If the Company issues any other rights to purchase
stock, warrants, securities or other property (the "PURCHASE RIGHTS") pro rata
to the record holders of any class of Common Stock, then the Holders will be
entitled to acquire, upon the terms applicable to such Purchase Rights, the
aggregate Purchase Rights which each Holder could have acquired if such Holder
had held the number of shares of Common Stock acquirable upon complete
conversion of this Note (subject to any limitation on conversion immediately
before the date on which a record is taken for the grant, issuance or sale of
such Purchase Rights, or, if no such record is taken, the date as of which the
record holders of Common Stock are to be determined for the grants, issue or
sale of such Purchase Rights.

        6.5  CERTAIN ACTIONS PROHIBITED. Without consent of the Required
Holders, the Company will not, by amendment of its charter 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 to be observed or performed by it
hereunder, but will at all times in good faith assist in the carrying out of all
the provisions of this Note and in the taking of all such actions as may
reasonably be requested by the Holder of

                                     - 15 -
<Page>

this Note in order to protect the conversion privilege of the Holder of this
Note, consistent with the tenor and purpose of this Note. Without limiting the
generality of the foregoing, the Company (i) will not increase the par value of
any shares of Common Stock receivable upon the exercise of this Note above the
Conversion Price then in effect, and (ii) will take all such actions as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock upon the conversion of this
Note.

        6.6  NOTICES OF ADJUSTMENT. Upon the occurrence of each adjustment or
readjustment pursuant to this Article VI, the Company, at its expense, shall
promptly compute such adjustment or readjustment and prepare and furnish to each
Holder a certificate, certified by the chief financial officer of the Company,
setting forth such adjustment or readjustment and showing in reasonable detail
the facts upon which such adjustment or readjustment is based, the Conversion
Price resulting from the adjustment, and the revised number of Conversion Shares
resulting from the adjustment. The Company shall, upon the written request at
any time of any Holder, furnish to such Holder a like certificate setting forth
(i) such adjustment or readjustment, (ii) the Conversion Price at the time in
effect and (iii) the number of shares of Common Stock and the amount, if any, of
other securities or property which at the time would be received upon conversion
of a Note.

                                  ARTICLE VII
                             AMENDMENTS AND WAIVERS

             AMENDMENT AND WAIVER. Except as otherwise expressly provided
herein, the provisions of the Notes may be amended, and the Company may take any
action herein prohibited, or omit to perform any act herein required to be
performed by it, if the Company has obtained the written consent of the Majority
Holders; PROVIDED that without the written consent of the Holders of all of the
outstanding principal amount of the Notes, the Company shall take no such action
which shall (i) reduce the rate at which or change the manner in which interest
accrues on the Notes or the times at which such interest becomes payable or is
paid, (ii) change any provision relating to the payments or prepayments of
principal on the Notes, (iii) change the provisions of Article III hereof or
(iv) change the requisite percentage of Holders required for the taking of any
such action described in this proviso.

                                  ARTICLE VIII
                                  MISCELLANEOUS

        8.1  FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the part
of a Holder in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

        8.2  NOTICE. Any notice herein required or permitted to be given shall
be in writing and may be personally served or delivered by courier or by
telecopy (confirmed by sending a copy by first class mail or courier within one
(1) day of sending by telecopy) and shall be deemed to have been given at the
time and date of receipt (which shall include telephone line facsimile
transmission). The addresses for such communications shall be:
