B A C K G R O U N D

WHEREAS, CPR and Blue Lake are parties to a Promissory Note, dated March 1, 2005, pursuant to which CPR owes Blue Lake the principal amount of $1,290,000 (the “Original Note”). The Original Note had a maturity date of March 31, 2008. CPR paid Blue Lake quarterly interest during the term of the Original Note; and

WHEREAS, this Note amends and restates in its entirety the Original Note.

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants and promises hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, CPR and Blue Lake, intending to be legally bound hereby, agree as follows

1. Principal and Interest Payments. Unless this Note is prepaid pursuant to Section 2 hereof or otherwise becomes due and payable on an earlier date in accordance with the terms hereof, the Principal Amount shall be due and payable as follows: (a) Two Hundred Thousand U.S. Dollars ($200,000), which Blue Lake acknowledges was paid to Blue Lake on April 8, 2008, (b) CPR shall pay Blue Lake Fifty Thousand U.S. Dollars ($50,000) on the first business day of each calendar month for twelve (12) consecutive months (totaling $600,000 in the aggregate), the first payment to occur on May 1, 2008 and the last to occur on April 1, 2009, and (c) on April 30, 2009, CPR shall pay to Blue Lake the balance of the Principal Amount, equal to Four Hundred and Ninety Thousand U.S. Dollars ($490,000), plus accrued interest. All interest shall be payable on April 30, 2009, unless this Note is prepaid in accordance with Section 2 or otherwise becomes due and payable on an earlier date in accordance with the terms hereof. All sums outstanding from time to time hereunder shall bear interest until the date paid at the rate of ten percent (10%) per annum. Interest shall accrue at the applicable rate on the basis of a 360-day year and the actual number of days elapsed.

2. Prepayment. CPR shall have the right to prepay from time to time without premium or penalty. Any prepayment shall be used to first to pay any accrued but unpaid interest and then, second, shall be applied to reduce the final balloon Principal Amount payment.

3. Escrow Agreement. This Note, and the due performance by CPR of all of its obligations hereunder, is secured by that certain escrow agreement (the “Escrow Agreement”), dated of even date herewith, by and among ClearPoint Business Resources, Inc., CPR and Blue Lake.

4. Event of Default.

a. Event of Default. Following the date hereof, the following events shall each constitute an “Event of Default”:

(i) if CPR shall fail to make any payment of principal or interest under this Note when such payment is due, which default shall remain uncured for five (5) business days after written notice of such failure shall have been given by Blue Lake to CPR;

(ii) if CPR or any individual guaranteeing or providing security for this Note shall enter into any agreement with one or more of its or their respective creditors regarding any moratorium with respect to its or their debts or the participation of any such creditors or their representatives in the supervision, management or control of the business of CPR or the assets of such individual;

(iii) if any bankruptcy or insolvency proceeding is commenced by CPR or any individual guaranteeing or providing security for this Note, or any such proceeding is commenced against CPR or any individual guaranteeing or providing security for this Note involuntarily and remains un-discharged for sixty (60) days or if a receiver or trustee is appointed to take possession of the property or assets of CPR or of any individual guaranteeing or providing security for the payment of this Note;

(iv) if CPR or any individual guaranteeing or providing security for the payment of this Note executes or agrees to a general assignment for the benefit of creditors; or

(v) if CPR or any individual guaranteeing or providing security for the payment of this Note consents to the entry of an order for relief against it in an involuntary bankruptcy or insolvency case, or if CPR or any such individual guaranteeing or providing security for the payment of this Note consents to the appointment of a trustee, receiver, liquidator or similar official.

b. Remedies on Default. Subject to Section 4(c), upon an Event of Default and at any time thereafter during the continuance of such Event of Default, without any further notice, demand, presentment, notice of protest or other action, at the election of Blue Lake, this Note shall be immediately due and payable, both as to the Principal Amount and any accrued but unpaid interest.

2

c. Guarantor Default. If any Event of Default is triggered due to the actions of any individual guaranteeing or providing security for the payment of this Note, then before electing to treat such an event as an Event of Default, Blue Lake shall provide CPR with three (3) business days to provide Blue Lake with reasonable assurances that Blue Lake will continue to get paid by CPR hereunder or that the shares subject to the Escrow Agreement will adequately cover the balance due hereunder.

5. Sale of Assets or Change of Control. Upon the consummation of an Event (as defined below) after the date hereof, without any further notice, demand, presentment, notice of protest or other action, at the election of Blue Lake, this Note shall be immediately due and payable, both as to Principal Amount and any accrued but unpaid interest. The term “Event” as used in this Section 5 shall mean (a) a sale of twenty-five percent (25%) or more of the assets of CPR, or (b) any consolidation, merger or share exchange of CPR in which the holders of CPR’s voting stock outstanding immediately prior to such consolidation, merger or share exchange do not in the aggregate hold a majority of the voting stock of the surviving or resulting entity outstanding immediately following such consolidation, merger or share exchange, excluding, however, (x) a merger or other reorganization solely for the purpose of changing CPR’s jurisdiction of organization or name, or (y) a merger of CPR with or into a wholly-owned subsidiary of CPR that is incorporated in the United States.
