                    Servicer on its behalf) shall take the following actions
                    and make the following determinations:

               (i) not less than five Business Days prior to the Removal and
          Repurchase Date (the "Removal and Repurchase Notice Date"), furnish
          to the Trustee, any Agent, any Enhancement Providers and the Rating
          Agencies a Removal Notice specifying the Designated Accounts which
          are to be removed, and the then existing Receivables in such
          Designated Accounts (the "Designated Receivables") which are to be
          repurchased, from the Trust and the Determination Date (which may be
          the Determination Date on which such notice is given) on which the
          removal of such Designated Accounts and the repurchase of such
          Designated Receivables will occur (a "Removal and Repurchase Date");

               (ii) on the Removal and Repurchase Date with respect to such
          Designated Accounts, amend Schedule 1 by delivering to the Trustee a
          computer file or microfiche or written list containing a true and
          complete list of the Removed Accounts specifying for each such
          Account, as of the Removal and Repurchase Notice Date, its account
          number and the aggregate amount of Receivables outstanding in such
          Account;

               (iii) on the Removal and Repurchase Date, deposit into the
          Collection Account funds in an amount equal to the aggregate
          outstanding balance of the Repurchased Receivables on such date (the
          "Repurchased Receivables Purchase Price"), which funds,
          notwithstanding anything in the Pooling and Servicing Agreement to
          the contrary, will not be released from the Collection Account other
          than pursuant to Section 4.03 (f) of the Pooling and Servicing
          Agreement;

               (iv) represent and warrant that the removal of any such
          Eligible Account and the repurchase of the Receivables then existing
          in such Account on any Removal and Repurchase Date shall not, in the
          reasonable belief of the Seller, cause an Early Amortization Event
          to occur or cause the Pool Balance to be less than the Required
          Participation Amount;

               (v) represent and warrant that no selection procedures believed
          by the Seller to be adverse to the interests of the Beneficiaries
          were utilized in selecting the Designated Accounts;

               (vi) represent and warrant as of the Removal and Repurchase
          Date that the list of Removed Accounts delivered pursuant to clause
          (ii) above, as of the Removal and Repurchase Date, is true and
          complete in all material respects;

               (vii) represent and warrant that such removal and repurchase
          will not result in a reduction or withdrawal of the rating of any
          outstanding Series or Class by the applicable Rating Agency;

               (viii) deliver to the Trustee, each Rating Agency, any Agent
          and any Enhancement Providers a Tax Opinion, dated the Removal and
          Repurchase Date, with respect to such removal and repurchase; and

               (ix) on or before the related Removal and Repurchase Date,
          deliver to the Trustee, any Agent and any Enhancement Providers an
          Officers' Certificate confirming the items set forth in clauses (iv)
          through (vii) above and confirming that the Seller reasonably
          believes that the removal of the Removed Accounts and the repurchase
          of the Repurchased Receivables will not result in the occurrence of
          an Early Amortization Event; the Trustee may conclusively rely on
          such Officers' Certificate and shall have no duty to make inquiries
          with regard to the matters set forth therein and shall incur no
          liability in so relying.

          No Designated Accounts shall be so removed and no Designated
          Receivables shall be so repurchased unless each Rating Agency shall
          have notified the Seller, the Servicer and the Trustee in writing
          that such removal and repurchase will not result in a reduction or
          withdrawal of the rating of any outstanding Series or Class by such
          Rating Agency."

               Repurchase Date with respect to any such Designated Account and
               Designated Receivables, such Designated Account shall be deemed
               removed, and such Designated Receivables ("Repurchased
               Receivables") shall be deemed repurchased, from the Trust for
               all purposes and the Trustee shall, without further action, be
               deemed to sell, transfer, assign, set over and otherwise convey
               to the Seller, effective as of the Removal and Repurchase Date,
               without recourse, representation or warranty, all the right,
               title and interest of the Trust in and to the Repurchased
               Receivables, all moneys due and to become due and all amounts
               received with respect thereto and all proceeds thereof. Within

     2. PURCHASE AND SALE OF COMMON STOCK

          a. PURCHASE AND SALE OF COMMON STOCK. Upon and subject to the terms
and conditions set forth herein, the Company may issue and sell to the
Purchaser, and the Purchaser shall purchase from the Company upon proper
exercise of the Company's rights hereunder, that number of Shares having an
aggregate Purchase Price of up to $125,000,000.

          b. DELIVERY OF DRAWDOWN NOTICES.

               (i) Subject to the satisfaction of the conditions set forth in
Section 2(g) below, at any time and from time to time during the Open Period,
the Company may, in its sole discretion, deliver a Drawdown Notice to the
Purchaser stating a dollar amount (the "STATED DOLLAR AMOUNT") of Shares which
the Company desires to sell to the Purchaser during the related Purchase Period;
provided, that a Drawdown Notice may not be delivered by the Company during an
existing Purchase Period. The Company shall designate in each Drawdown Notice a
minimum Purchase Price per Share with regard to the related Purchase Period,
which shall not be less than the Floor Price or greater than the Ceiling Price
(a "COMPANY DESIGNATED MINIMUM PRICE"). If the Company fails to designate a
Company Designated Minimum Price in a Drawdown Notice, the Company Designated
Minimum Price for the related Purchase Period shall be the Floor Price. The
Company may not deliver more than 20 Drawdown Notices during

<PAGE>

the Open Period.

          (ii) The Stated Dollar Amount designated by the Company in a Drawdown
Notice shall be in increments of $100,000 and shall be at least $500,000, but
shall in no event exceed $7,500,000. In addition, the Stated Dollar Amount
designated by the Company in a Drawdown Notice may not be greater than the
product of (A) the Floor Price and (B) the number of shares of Common Stock then
currently available under the Registration Statement.

          (iii) Contemporaneous with the delivery of a Drawdown Notice, the
Company shall deliver to the Purchaser (A) a copy of the then current prospectus
or prospectus supplement to the Registration Statement in accordance with the
rules and regulations under the 1933 Act, (B) the other documents required to be
delivered pursuant to Sections 7(e), 7(f), 7(h) and 7(i) below, and (C)
reimbursement for any previously unreimbursed expenses as provided in Section
10(b) below. Purchases required as a result of a Drawdown Notice shall be
effected by the parties in accordance with Section 2(h) below.

     c. ADJUSTMENT OF THE DAILY DOLLAR AMOUNT.

     On each Trading Day during a Purchase Period, the Daily Dollar Amount
for such Trading Day shall be subject to adjustment as follows:

               (i) For each Trading Day during the Purchase Period on which
(A) 94% of the VWAP for such Trading Day is less than the Company Designated
Minimum Price and (B) the product of (x) the Company Designated Minimum Price
and (y) the number of Shares (if any) sold by the Purchaser during such Trading
Day in accordance with the plan of distribution contained in the Registration
Statement at a price greater than or equal to the Company Designated Minimum
Price (such number of Shares being referred to herein as the "SOLD SHARE
AMOUNT"), is less than the Daily Dollar Amount, the Daily Dollar Amount shall be
reduced automatically to equal the Company Designated Minimum Price multiplied
by the Sold Share Amount. For the avoidance of any doubt, for each Trading Day
during the Purchase Period on which (m) 94% of the VWAP for such Trading Day is
less than the Company Designated Minimum Price and (n) the Company Designated
Minimum Price multiplied by the Sold Share Amount is greater than the Daily
Dollar Amount, then the Daily Dollar Amount shall not be adjusted. For the
further avoidance of any doubt, for each Trading Day during the Purchase Period
on which (r) 94% of the VWAP for such Trading Day is less than the Company
Designated Minimum Price and (s) the Sold Share Amount equals zero, then the
Daily Dollar Amount shall equal zero.

               (ii) For each Trading Day during the Purchase Period on which
(A) the Registration Statement or any prospectus or prospectus supplement is not
available for the sale of Shares by the Purchaser or (B) trading of the Common
Stock on the Principal Market is suspended or halted for more than 1 hour at any
time during which the Principal Market is open for trading, or (C) trading on
the Principal Market in general is suspended or halted for more than 1 hour (the
full Trading Day less such period of unavailability or suspension being referred
to as the "AVAILABLE PERIOD"), the Daily Dollar Amount for such Trading Day
shall be automatically reduced (but not increased) to equal to the product of
(x) the number of Shares sold by the

<PAGE>

Purchaser during the Available Period in accordance with the plan of
distribution contained in the Registration Statement at a price greater than or
equal to the Company Designated Minimum Price, and (y) the Purchase Price per
Share (with the VWAP component of the Purchase Price being calculated with
respect to the Available Period only).

               (iii) For each Trading Day during the Purchase Period on which
the Daily Dollar Amount for such Trading Day would exceed 13.64% of the
Preceding Average Daily Dollar Volume, the Daily Dollar Amount for such Trading
Day shall be automatically reduced to equal 13.64% of the Preceding Average
Daily Dollar Volume.

          In the case that more than one of the above adjustments to the Daily
Dollar Amount is applicable on a given Trading Day, only the adjustment that
results in the lowest Daily Dollar Amount for such Trading Day shall apply and
be effected. The Daily Dollar Amount for a particular Trading Day as reduced in
accordance with Sections 2(c)(i), 2(c)(ii) or 2(c)(iii) above shall be referred
to as the "ADJUSTED DAILY AMOUNT" for such Trading Day. For the avoidance of
doubt, this reduction in the Daily Dollar Amount for such Trading Day shall not
affect the calculation of the Daily Dollar Amount or Adjusted Daily Amount for
any other Trading Day.

          In addition, with respect to any particular Trading Day, the Purchaser
shall not be obligated to purchase a number of Shares greater than the lowest of
(A) the Daily Dollar Amount (or, if applicable, the Adjusted Daily Amount) for
such Trading Day divided by the Purchase Price for such Trading Day, (B) 25% of
such Trading Day's trading volume for the Common Stock on the Principal Market
as reported by Bloomberg Financial L.P., and (C) 15% of the previous Trading
Day's trading volume for the Common Stock on the Principal Market as reported by
Bloomberg Financial L.P. (such lowest amount as calculated pursuant to clauses
(A), (B) and (C) above being referred to herein as the "PURCHASER DAILY SHARE
OBLIGATION" or "PDSO" and with the PDSO for a particular Trading Day multiplied
by the Purchase Price for such Trading Day being referred to herein as the "PDSO
DOLLAR AMOUNT"); PROVIDED, that in the case of clauses (B) and (C) above,
individual trades of at least 60,000 shares of Common Stock shall for purposes
of such clauses each be treated as a trade of 60,000 shares of Common Stock.

          For the avoidance of any doubt, all calculations performed with
respect to this Section 2(c) will be performed with respect to the Trading Day
on which the sale of Shares to the Purchaser is deemed to occur, not the
corresponding Closing Date.

          d. PURCHASER'S OBLIGATION TO PURCHASE SHARES. Subject to the
conditions set forth in this Agreement, following the Purchaser's receipt of a
validly delivered Drawdown Notice, the Purchaser shall be required to purchase
from the Company with respect to each Trading Day during the related Purchase
Period a number of Shares having an aggregate Purchase Price at least equal to
the PDSO Dollar Amount for such Trading Day at the Purchase Price per Share for
such Trading Day (with the VWAP component of Purchase Price per Share calculated
only with respect to the Available Period during such Trading Day if the Daily
Dollar Amount for such Trading Day has been adjusted pursuant to Section
2(c)(ii)). The Purchaser shall, in no event, be required to purchase pursuant to
this Agreement a number of Shares having an aggregate

<PAGE>

Purchase Price which is greater than $125,000,000.

          e. DELIVERY OF EFFECTIVENESS NOTICE. The Company shall, at least 5
Trading Days in advance of the day it anticipates will be the Effective Date,
deliver to the Purchaser a notice (the "EFFECTIVENESS NOTICE") identifying the
anticipated Effective Date. If the Effective Date has not yet occurred as of one
month after the date specified in such a notice, the Company will be required to
provide a new Effectiveness Notice with respect to the then-anticipated
Effective Date, in accordance with the preceding sentence. The Company shall use
its good faith efforts to predict the Effective Date in any Effectiveness Notice
it delivers and shall have no liability with respect to such prediction if the
actual Effective Date is earlier or later than predicted in the Effectiveness
Notice.

          f. LIMITATIONS ON PURCHASER'S OBLIGATION AND RIGHT TO PURCHASE SHARES.
Notwithstanding anything to the contrary in this Agreement, the number of shares
of Common Stock that may be acquired by the Purchaser at any specific time
pursuant hereto shall not exceed a number that, when added to the total number
of shares of Common Stock deemed beneficially owned at such time by the
Purchaser (other than by virtue of the ownership of securities or rights to
acquire securities that have limitations on the Purchaser's right to convert,
exercise or purchase similar to the limitation set forth herein), together with
all shares of Common Stock deemed beneficially owned at such time (other than by
virtue of the ownership of securities or rights to acquire securities that have
limitations on the right to convert, exercise or purchase similar to the
limitation set forth herein) by the Purchaser's "affiliates" (as defined in Rule
144 of the 1933 Act) (the "AGGREGATION PARTIES") that would be aggregated for
purposes of determining whether a group under Section 13(d) of the Exchange Act
exists, would exceed 9.99% of the total issued and outstanding shares of the
Common Stock (the "RESTRICTED OWNERSHIP PERCENTAGE"). In connection with the
foregoing limitation, the Daily Dollar Amount, or, if applicable, the Adjusted
Daily Amount, and/or the PDSO Dollar Amount, shall be further reduced such that
it shall not include such excess amount of shares of Common Stock. If at any
time, the ten percent beneficial ownership trigger level contained in Section
16(a) of the Exchange Act is reduced, the Restricted Ownership Percentage shall
be automatically reduced to .01% below such reduced trigger level.

          The Purchaser covenants at all times on each day (each such day being
referred to as a "COVENANT DAY") as follows: During the balance of such Covenant
Day and the succeeding 61 days (the balance of such Covenant Day and the
succeeding 61 days being referred to as the "COVENANT PERIOD") the Purchaser
will not acquire shares of Common Stock pursuant to any right (including
pursuant to Section 2 of this Agreement) existing at the commencement of the
Covenant Period to the extent the number of shares so acquired by the Purchaser
and its Aggregation Parties (ignoring all dispositions) would exceed:

               (x) the Restricted Ownership Percentage of the total number of
                   shares of Common Stock outstanding at the commencement of
                   the Covenant Period, MINUS

               (y) the number of shares of Common Stock actually owned by the

<PAGE>

                   Purchaser and its Aggregation Parties at the commencement
                   of the Covenant Period.

          A new and independent covenant will be deemed to be given by the
Purchaser as of each moment of each Covenant Day. No covenant will terminate,
diminish or modify any other covenant. The Purchaser agrees to comply with each
such covenant. This Section 2(f) controls in the case of any conflict with any
other provision of this Agreement or any agreement entered into in connection
herewith.

          Each Drawdown Notice shall include a representation by the Company as
to the number of shares of Common Stock outstanding as of the last day of the
calendar month immediately preceding the related Drawdown Notice Date.

          The Purchaser shall notify the Company when it becomes aware that it
will not be permitted to purchase Shares as a result of the provisions of this
Section 2(f). The Company shall have no obligation to sell Shares to the
Purchaser and the Purchaser shall have no obligation to purchase Shares from the
Company that may not be acquired by the Purchaser by reason of the provisions of
this Section 2(f). The Purchaser shall have no liability for any failure to
purchase Shares from the Company that are not permitted to be acquired by the
Purchaser pursuant to this Section 2(f).

          Nothing contained in this Section 2(f) shall affect or relieve in any
way the Company's obligation to deliver Shares previously purchased by the
Purchaser pursuant to this Agreement as to which there has not been a Closing
(as defined below).

          g. CONDITIONS TO COMPANY'S ABILITY TO DELIVER A DRAWDOWN NOTICE.
Notwithstanding anything to the contrary in this Agreement, the Company shall
not be entitled to deliver a Drawdown Notice unless each of the following
conditions is satisfied at the time of such delivery:

               (i) a Registration Statement covering the applicable number of
shares of Common Stock as set forth in Section 2(g)(vi) below shall have been
declared effective in accordance with the Registration Rights Agreement and such
Registration Statement, together with any required prospectus supplement, shall
be effective and available for the sale of such Shares by the Purchaser and all
Shares previously purchased by the Purchaser hereunder and then held by the
Purchaser;

               (ii) the Common Stock shall be listed and/or quoted on an
Approved Market and shall not have been suspended from trading thereon, and the
Company shall not have been notified of any pending or threatened proceeding or
other action to delist or suspend the Common Stock on the Principal Market;

               (iii) there shall not have occurred a Major Transaction or the
public announcement of a pending Major Transaction which has not been abandoned
or terminated;

               (iv)  the Company shall have complied with its obligations under
all the

<PAGE>

Transaction Documents and shall otherwise not be in breach of, or in default
under, any of the Transaction Documents;

               (v) there shall not have occurred any breach or default by the
Company under any other agreements between the Company and the Purchaser;

               (vi) a number of shares of Common Stock equal to at least
3,000,000 (or, if less, the greatest number of shares of Common Stock that the
Company is then permitted to register pursuant to the 1933 Act and the rules and
regulations promulgated thereunder) shall have been duly authorized and reserved
for issuance with respect to the applicable Purchase Period and shall be
available for sale under the Registration Statement, and

               (vii) the Company shall have delivered to the Purchaser a
secretary's certificate dated as of the applicable Drawdown Notice Date in the
form and substance of EXHIBIT D.

          The Company's delivery of a Drawdown Notice shall constitute a
representation by the Company that the shares of Common Stock referred to in
clause (vi) above have been reserved for issuance as required pursuant to this
Section 2(g). If any of the events described in clauses (iii) and (v) above
occurs, or the Company ceases to be in compliance with one or more of the
conditions specified in clauses (i), (ii), (iv) and (vi) above, during a
Purchase Period, then the Purchaser shall have no further obligation to purchase
any additional Shares during such Purchase Period, although the Company's
obligation to deliver Shares previously purchased by the Purchaser pursuant to
this Agreement as to which there has not been a Closing (as defined below) shall
not be affected or relieved in any way as a result of any of the above
conditions not being fulfilled by the Company.

          h. MECHANICS OF PURCHASE OF SHARES BY PURCHASER.

               (i) To effect a purchase of Shares during a Purchase Period,
the Purchaser shall deliver on each Purchase Day of the Purchase Period, a
written notice via facsimile or e-mail to the Company (each a "PURCHASE NOTICE")
by 11:59 p.m. New York City time on such Purchase Day. Each Purchase Notice
shall set forth:

                   (A) the aggregate Purchase Price for the Shares being
                       purchased by the Purchaser pursuant to such Purchase
                       Notice, such aggregate Purchase Price being no less than
                       the PDSO Dollar Amount and no greater than the Daily
                       Dollar Amount or, if applicable, the Adjusted Daily
                       Amount (with the aggregate Purchase Price specified
                       within such range being binding);

                   (B) the Purchase Price per Share;

                   (C) the number of Shares being purchased pursuant to such
                       Purchase Notice;

                   (D) the date of the closing of the purchase by the Purchaser
                       of such
<PAGE>

                       Shares (a "CLOSING") (which shall occur not later than
                       10:00 a.m. New York City time on the 11th Trading Day
                       after the date of the Purchase Notice, at the offices
                       of Kleinberg, Kaplan, Wolff & Cohen, P.C.,
                       551 Fifth Avenue, New York, New York 10176); and

                   (E) that the Purchaser is then in compliance with the
                       covenant contained in Section 5(l) below.

     The date of each Closing is referred to herein as a "CLOSING DATE."

          (ii) Notwithstanding anything herein to the contrary, the parties
agree that the Purchaser will be deemed to own the Shares to be purchased with
respect to a particular Purchase Day as of such Purchase Day, regardless of the
associated Closing Date.

          (iii) On each Closing Date, (A) the Company shall either (x) deliver
to the Purchaser certificates representing the Shares to be issued and sold to
the Purchaser on such date, registered in the name of the Purchaser or its
designee and free of any legends and stop transfer restrictions or (y) deposit
such Shares into the account(s) (with the Purchaser receiving confirmation that
the Shares are in such account(s)) designated by the Purchaser for the benefit
of the Purchaser, and (B) the Purchaser shall deliver to the Company the
aggregate Purchase Price (net of any amounts payable by the Company pursuant
hereto) to be paid for such Shares (upon receipt of confirmation of delivery of
such Shares), determined as aforesaid, in immediately available funds. In
addition, each of the Company and the Purchaser shall deliver all documents,
instruments and writings required to be delivered by either of them pursuant to
this Agreement, at or prior to each Closing. In the alternative to physical
delivery of certificates representing Common Stock, if delivery of the Shares
may be effectuated by electronic book-entry through DTC, then the Closing shall
occur, and delivery of the Shares pursuant to such purchase shall, unless
requested otherwise by the Purchaser, settle by book-entry transfer through DTC
by the Closing Date. The parties agree to coordinate with DTC to accomplish this
objective.

          (iv) If the Company fails to deliver the appropriate number of Shares
to the Purchaser within 1 Trading Day following the date on which the Closing
with respect to such Shares was scheduled as provided above (the "SCHEDULED
CLOSING DATE") for any reason, the Purchaser shall not purchase any additional
Shares from the Company pursuant to this Agreement until such failure has been
fully cured by the Company and the appropriate number of Shares has been
delivered to the Purchaser, and the Purchase Period shall be extended by a
number of Trading Days equal to the number of Trading Days from the Scheduled
Closing Date to the date of such cure. If such failure is not cured by the
Company by the close of business on the 4th Trading Day following the Scheduled
Closing Date (1) the current Purchase Period shall immediately terminate and the
Purchaser shall have no further obligation to purchase any additional Shares
from the Company with respect to such terminated Purchase Period, and (2) the
Purchaser may, from time to time during the 10 Trading Day period following such
4th Trading Day, purchase in the open market the number of Shares that the
Company failed to deliver and the Company shall, upon receipt of notice of such
purchase, as partial relief for the damages to

<PAGE>

the Purchaser by reason of the above-described failure, reimburse the Purchaser
for the cost of such purchase (each such purchase and reimbursement being a
"BUY-IN"), promptly following which time the Purchaser shall deliver to the
Company the aggregate Purchase Price to be paid for such Shares, determined as
aforesaid, in immediately available funds. If the Company fails to pay such
reimbursement within 3 Trading Days of receipt of such notice, then the Company
shall pay to the Purchaser, on the 1st Trading Day following such 3rd Trading
Day, in addition to, and not in lieu of, the reimbursement amount payable by the
Company to the Purchaser hereunder, an amount equal to 2% of the reimbursement
amount per period of 22 Trading Days (or portion thereof) until the
reimbursement amount is paid in full. If no Buy-in occurs with respect to a
certain number of Shares and the Company's failure to deliver such Shares to the
Purchaser is not cured by the Company by the close of business on the 13th
Trading Day following the Scheduled Closing Date, this Agreement shall terminate
(subject to Section 10(j) below) upon the delivery by the Purchaser to the
Company of a notice regarding such excessively delayed Closing (a "DELAYED
CLOSING NOTICE"), and following its delivery of such notice, the Purchaser shall
have no further obligation to purchase any additional Shares from the Company
under this Agreement. The remedies set forth in this Section 2(h)(iv) are not
exclusive of any other remedies available to the Purchaser at law or equity.

          (v) If the Company fails to satisfy any of the conditions set forth in
Section 7 below (including, without limitation, Section 7(l)) on any Purchase
Day or Scheduled Closing Date, the Purchaser shall not purchase any additional
Shares from the Company pursuant to this Agreement until such condition has been
fully satisfied by the Company and the Purchase Period shall be extended by a
number of Trading Days equal to the number of Trading Days from such Purchase
Day or Scheduled Closing Date (as applicable) to the date of such satisfaction
by the Company. If such condition is not fully satisfied by the Company by the
close of business on the 4th Trading Day following such Purchase Day or
Scheduled Closing Date (as applicable), the current Purchase Period shall
immediately terminate, and the Purchaser shall have no further obligation to
purchase any additional Shares from the Company with respect to such terminated
Purchase Period. If such condition is not fully satisfied by the Company by the
close of business on the 13th Trading Day following such Purchase Day or
Scheduled Closing Date (as applicable), this Agreement shall terminate (subject
to Section 10(j) below) upon the delivery to the Company of a Delayed Closing
Notice and, following its delivery of such notice, the Purchaser shall have no
further obligation to purchase any additional Shares from the Company under this
Agreement; provided, however, that the Purchaser may not deliver a Delayed
Closing Notice during the pendency of a Suspension Period (as defined in the
Registration Rights Agreement). The remedies set forth in this Section 2(h)(v)
are not exclusive of any other remedies available to the Purchaser at law or
equity and shall not affect or relieve in any way the Company's obligation to
deliver Shares previously purchased by the Purchaser pursuant to this Agreement
as to which there has not been a Closing.

          (vi) The number of Shares to be purchased pursuant to each Purchase
Notice shall be rounded to the nearest whole number so as to avoid the issuance
of fractional shares.

          (vii) Notwithstanding anything herein to the contrary, there shall be
a maximum of 7 Closings scheduled by the parties with respect to any particular
Purchase Period

<PAGE>

excluding any Closings at which either one or both of the parties fails to
perform its obligations under this Agreement.

          i. CERTAIN ADJUSTMENTS. Preceding Average Daily Dollar Volume as well
as the limitations imposed by Sections 2(f), 2(k), and the final paragraph of
2(c) hereof on the number of Shares acquirable, shall be adjusted appropriately
to reflect stock splits, reverse stock splits, stock dividends, combinations and
like transactions affecting the Common Stock. Such appropriate adjustments shall
be made for any period of Trading Days used for purposes of performing
calculations under this Agreement.

          j. DELISTING; SUSPENSION. If at any time during a Purchase Period or
during the 10 Trading Days after the end of such Purchase Period, (i) the
Registration Statement, together with the required prospectus or prospectus
supplement, shall not be effective and available for sale of all the Shares, or
(ii) the Common Stock and Shares shall not be listed on the Principal Market or
shall have been suspended from trading thereon, the Purchaser shall have the
right (the "REPURCHASE OPTION"), as partial relief for the damages to the
Purchaser by reason of the occurrence of the events listed in clauses (i) or
(ii) above (each a "REPURCHASE Event"), which remedy shall not be exclusive of
any other remedies available at law or equity, in its sole discretion, to sell
to the Company, and the Company agrees to buy, promptly upon the exercise of
such right by the Purchaser, but in any event within 3 Trading Days of the
exercise of such right, all or any part of the Shares issued to the Purchaser
during such Purchase Period and then held by the Purchaser, at the price per
Share at which such Shares were actually purchased by the Purchaser (the
"PAYMENT AMOUNT") (such repurchase being a "REPURCHASE CLOSING").
Notwithstanding anything else in this Section 2(j) to the contrary, in the event
that the consummation of a Repurchase Closing would constitute a violation of
Regulation M promulgated under the Exchange Act, (A) the Purchaser shall have
the right to immediately terminate this Agreement (subject to Section 10(j)
below) upon written notice to the Company (such termination being deemed by both
parties hereto as a termination of the related "Distribution" pursuant to Rule
100 under Regulation M), and (B) such Repurchase Closing shall be postponed
until immediately following such termination of this Agreement. If the Company
fails to pay to the Purchaser the full aggregate Payment Amount within 3 Trading
Days of the Purchaser's exercise of the Repurchase Option hereunder (or, if the
Repurchase Closing is postponed pursuant to the immediately preceding sentence,
within 3 Trading Days of the date on which the Purchaser terminated this
Agreement pursuant to clause (A) above) the Company shall pay to the Purchaser,
on the 1st Trading Day following such 3rd Trading Day, in addition to and not in
lieu of the Payment Amount payable by the Company to the Purchaser upon exercise
of the Repurchase Option, an amount equal to 2% of the Payment Amount per period
of 22 Trading Days (or portion thereof) until the Payment Amount is paid in
full. The Purchaser may in its sole discretion, without prejudice, withdraw such
exercise of its Repurchase Option in whole or part from time to time prior to
the payment in full to the Purchaser of the amounts specified in this Section
2(j).

          k. OVERALL LIMIT ON COMMON STOCK ISSUABLE. Notwithstanding anything
contained herein to the contrary, the number of Shares issuable by the Company
to the Purchaser and purchasable by the Purchaser from the Company hereunder
shall not exceed 19.99% of the shares

<PAGE>

of Common Stock outstanding as of the date hereof, subject to appropriate
adjustment for stock splits, reverse stock splits, stock dividends, combinations
or other similar recapitalizations affecting the Common Stock (the "MAXIMUM
COMMON STOCK ISSUANCE"), unless (i) the issuance of Shares hereunder in excess
of the Maximum Common Stock Issuance shall first be approved by the Company's
shareholders in accordance with applicable law and the by-laws and articles of
incorporation of the Company, or (ii) independent counsel for the Company
determines that such shareholder approval is not required by the rules of the
market or exchange on which the Common Stock is principally traded, and so
notifies the Purchaser. Without limiting the generality of the foregoing, such
shareholders' approval (if applicable) must duly authorize the issuance by the
Company of shares of Common Stock totaling more than 19.99% of the shares of
Common Stock outstanding on the date hereof. The parties understand and agree
that the Company's failure to seek or obtain such shareholder approval shall in
no way adversely affect the validity and due authorization of the issuance and
sale of Shares hereunder, and that such approval pertains only to the
applicability of the Maximum Common Stock Issuance limitation provided in this
Section 2(k).

in connection with registered underwritten public offerings in which Company
Counsel represents the issuer.

          l. SHORT SALES. The Purchaser shall not assume or maintain a net short
position in the Common Stock, except to the extent reasonably necessary to hedge
the Purchaser's net long exposure to the Common Stock resulting from (i) its
actual purchases of Shares pursuant to this Agreement on all completed Purchase
Days for which there has not yet been a Closing plus (ii) its reasonably
anticipated purchases of Shares pursuant to this Agreement over a period not to

Agreement, adjusted as applicable. Notwithstanding the above, in no event shall
the Purchaser's indemnification obligations under this Agreement exceed the
aggregate net proceeds received by the Purchaser from its sale of Shares
purchased from the Company pursuant to this Agreement.

          b. EXPENSES.

               (i) As an inducement to the Purchaser to enter into this
Agreement, the Company agrees to reimburse the Purchaser or its counsel,
designees or clients, as applicable, for all reasonable fees and expenses
actually incurred (including reasonable legal expenses) relating to the initial
and ongoing due diligence and the negotiation and execution of the Transaction
Documents. The Company will pay to the Purchaser and/or its counsel, at the time
of signing this Agreement, for an estimate of all such costs and expenses
incurred as of such date of signing. If the Purchaser or its counsel (as the
case may be) discovers that such estimates were higher than actual costs and
expenses, it will reimburse any excess to the Company within 30 days of such
discovery to extent such excess is not offset against other or further
reimbursable expenses. To the extent such estimate does not so cover all such
reimbursable costs and expenses, the Company shall promptly pay the Purchaser
and/or its counsel the amount of such deficiency promptly following demand
therefor. Notwithstanding the above, the Company's payment obligations to the
Purchaser under this Section 10(b)(i) shall be limited to $70,000 with respect
to costs, fees and expenses incurred by the Purchaser prior to the initial
Drawdown Notice Start Date under this Agreement, and $15,000 (or $20,000 for any
quarter during which the Company files a Registration Statement on a form other
than Form S-3 or in which the then effective Registration Statement is on a form
other than Form S-3) with respect to costs, fees and expenses incurred by the
Purchaser during each calendar quarter thereafter; PROVIDED that to the extent a
payment limit is not fully utilized in any period, the amount of such unused
availability shall carry forward and be available to the Purchaser in one or
both of the two immediately succeeding periods.

               (ii) Except as otherwise set forth in this Section 10(b) or
Section 9 above or set forth in the Registration Rights Agreement, each party
shall pay the fees and expenses of its advisers, counsel, accountants and other
experts, if any, and all other expenses incurred by such party incident to the
negotiation, preparation, execution, delivery and performance of the
transactions contemplated by the Transaction Documents. Any attorneys' fees and
expenses incurred by either the Company or by the Purchaser in connection with
the preparation, negotiation, execution and delivery of any amendments to this
Agreement or relating to the enforcement of the rights of any party, after the
occurrence of any breach of the terms of this Agreement by another party or any
default by another party in respect of the transactions contemplated hereunder,
shall be paid on demand by the party which breached the Agreement and/or
defaulted, as the case may be. The Company shall pay all stamp and other taxes
and duties levied in connection with the issuance of any Shares issued pursuant
hereto.

          c. COUNTERPARTS. This Agreement may be executed in two or more
identical counterparts, all of which shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each
party and delivered to the other party; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

<PAGE>

          d. HEADINGS. The headings of this Agreement are for convenience of
reference and shall not form part of, or affect the interpretation of, this
Agreement.

          e. SEVERABILITY. If any provision of this Agreement shall be invalid
or unenforceable in any jurisdiction, such invalidity or unenforceability shall
not affect the validity or enforceability of the remainder of this Agreement in
that jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction.

          f. ENTIRE AGREEMENT; AMENDMENTS; WAIVERS. This Agreement supersedes
all other prior oral or written agreements between the Purchaser and the Company
with respect to the matters discussed herein, and this Agreement and the
instruments referenced herein (including the other Transaction Documents)
contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor the Purchaser makes any representation,
warranty, covenant or undertaking with respect to such matters. No provision of
this Agreement may be amended other than by an instrument in writing signed by
the Company and the Purchaser, and no provision hereof may be waived other than
by an instrument in writing signed by the party against whom enforcement is
sought. The Purchaser may at any time elect, by notice to the Company, to waive
(whether permanently or temporarily, and subject to such conditions, if any, as
the Purchaser may specify in such notice) any of its rights, any of the
Company's obligations to the Purchaser, or any of the conditions precedent with
which the Company must comply that are for the sole benefit of the Purchaser,
with respect to or in connection with the Purchaser's acquisition of Common
Stock from the Company pursuant to the Transaction Documents, in which event
such waiver shall be binding against the Purchaser in accordance with its terms.

          g. NOTICES. Any notices, consents, waivers or other communications
required or permitted to be given under the terms of this Agreement must be in
writing, must be delivered by (i) a nationally recognized delivery service, mail
or hand delivery OR (ii) facsimile, and will be deemed to have been delivered
(A) upon receipt, when delivered via delivery service; or (B) upon receipt, when
sent by facsimile (provided confirmation of transmission is mechanically or

          h. SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, this
Agreement shall be binding upon and inure to the benefit of the parties and
their respective successors and assigns, including any Permitted Assignee (as
defined below). The Company shall not assign this Agreement or any rights or
obligations hereunder without the prior written consent of the Purchaser,
including by merger or consolidation. The Purchaser may assign some or all of
its rights hereunder to an Affiliate, without the consent of the Company, and to
others, with the written consent of the Company (in each case, a "PERMITTED
ASSIGNEE"); provided, however, that

<PAGE>

each such assignee shall be required to confirm in writing its agreement to be
bound by the terms of this Agreement, and provided further, that any such
assignment shall not release the Purchaser from its obligations hereunder unless
such obligations are assumed by such assignee. Notwithstanding anything to the
contrary contained in the Transaction Documents, the Purchaser shall be entitled
to pledge the Shares in connection with a bona fide margin account.

          i. NO THIRD PARTY BENEFICIARIES. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

          j. SURVIVAL. The representations and warranties of the Company and the
Purchaser contained in Sections 3 and 4, the agreements and covenants (with
respect to any deliveries of Shares not yet made by the Company and any
purchases of Shares not yet made by the Purchaser that, in each case, are
required to be made by such party pursuant to this Agreement) set forth in
Sections 2(h)(iii), 2(h)(iv), 2(h)(v), 2(j), 2(k), 5 (except for Sections 5(j),
(k), (l), (m) and (n)), 6, 7 and 10, and the indemnification provisions set
forth in Section 9, shall survive each of the Closings, the termination of the
Open Period and the termination of this Agreement, regardless of whether this
Agreement is terminated automatically or by one or both of the parties hereto,
for a period of 3 years following the termination of this Agreement.

          k. PUBLICITY. The Company and the Purchaser shall have the right to
approve before issuance any press releases or any other public statements with
respect to the transactions contemplated hereby; provided, however, that the
Company shall be entitled, without the prior approval of the Purchaser, to make
any press release or other public disclosure with respect to such transactions
as is required by applicable law and regulations (although the Purchaser shall
be consulted by the Company in connection with any such press release or other
public disclosure prior to its release and shall be provided with a copy
thereof).

          l. FURTHER ASSURANCES. Each party shall do and perform, or cause to be
done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

          m. PLACEMENT AGENT. The Purchaser and the Company each acknowledges
and warrants that it has not engaged any placement agent in connection with the
sale of the Shares, other than Ladenburg Thalmann & Co. Inc., whose fees will be
paid exclusively by the Company. The Company and the Purchaser shall each be
responsible for the payment of any fees or commissions of placement agents or
brokers engaged, directly or indirectly, by the Company or the Purchaser,
respectively, in connection with the purchase of the Shares by the Purchaser.
The Company and the Purchaser shall pay, and hold the other party harmless
against, any liability, loss or expense (including, without limitation,
reasonable attorneys' fees and out-of-pocket expenses) arising in connection
with any such claim.

          n. NO STRICT CONSTRUCTION. The language used in this Agreement will be
deemed to be the language chosen by the parties to express their mutual intent,
and no rules of strict

<PAGE>

construction will be applied against any party.

          o. REMEDIES. The Purchaser and each Permitted Assignee shall have all
rights and remedies set forth in this Agreement and the Registration Rights
Agreement and all rights and remedies which such holders have been granted at
any time under any other agreement or contract and all of the rights which such
holders have under any law. Any person having any rights under any provision of
this Agreement shall be entitled to enforce such rights specifically (without
posting a bond or other security), to recover damages by reason of any breach of
any provision of this Agreement and to exercise all other rights granted by law.
The Purchaser and each Permitted Assignee without prejudice may withdraw, revoke
or suspend its pursuit of any remedy at any time prior to its complete recovery
as a result of such remedy. Notwithstanding the foregoing, in no event shall
either party be liable to the other party for any indirect, incidental,
consequential, special or exemplary damages arising from or in connection with
this Agreement or the Registration Rights Agreement (other than pursuant to a
party's indemnification obligations under Section 6 of the Registration Rights
Agreement) even if such party has been advised of the possibility of such
damages.

          p. PAYMENT SET ASIDE. To the extent that the Company makes a payment
or payments to the Purchaser hereunder or under the Registration Rights
Agreement or the Purchaser enforces or exercises its rights hereunder or
thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside, recovered from, disgorged by or are
required to be refunded, repaid or otherwise restored to the Company, a trustee,
receiver or any other person under any law (including, without limitation, any
bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such enforcement or setoff
had not occurred.

          q. DAYS. Unless the text refers to "Trading Days" or "Purchase Days,"
all references herein to "days" shall mean calendar days.

          r. RESCISSION AND WITHDRAWAL RIGHT. Notwithstanding anything to the
contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, wherever the Purchaser exercises a right, election,
demand or option under a Transaction Document and the Company does not fully
perform its related obligations within the periods therein provided, then the
Purchaser in its sole discretion may rescind or withdraw from time to time any
relevant notice, demand or election in whole or in part without prejudice to its
future actions and rights.
