          (c) Indebtedness. UBEI or UBES shall pay directly to the holders of the Permitted Liabilities listed on Schedule 2.2(c) which is outstanding as of the Closing Date, as specified in one or more pay-off letters.

     2.3 Application of Certain Unidentified Customer Proceeds. In the event that during the one year period commencing on the Closing Date, payments are received from any account debtor which do not specify whether they are to be applied to receivables dated prior to or after the Effective Date, the party receiving payment shall inform the other party of same, and Buyer and Seller shall coordinate jointly to contact the account debtor to determine the receivable to which such payment shall be applied. In the event it cannot be determined after attempting to contact account debtor, Buyer and Seller shall split such amount equally. In the event that during the one year period commencing on the Closing Date payments are received from a customer of the Business that does not have amounts outstanding for pre or post Effective Date transactions at the time such funds are received, and such payment does not otherwise specify which invoice it shall be applied to or otherwise direct the disposition of such proceeds, then the funds received shall be shared equally (50/50) between Buyer and Seller. The provisions of Section 2.4(c) shall apply to any amounts received from a customer of the Business. The party receiving such proceeds shall promptly remit to the other party, such other party’s proportionate share of such funds on each Monday and Thursday following the receipt of such amounts, provided such receiving party shall have determined that all amounts collected with respect

EXECUTION COPY

thereto are good funds. Each party shall provide the other party with a report within 10 business days following the expiration of each calendar month, summarizing the funds received by such party during the prior calendar month, including the date such funds were received, an indication as to how such funds were applied, together with a copy of the check or remittance advice from the customer.

     2.4 Ineligible Receivable Earn Out. The Ineligible Receivable Earn Out Period shall commence with the Effective Date and terminate on September 30, 2009. The following provisions shall apply to the Ineligible Receivables (herein the “Ineligible Receivables Earn Out”):

          (a) US Bio Receivables and Seller Holdback Receivables. The US Bio Receivables, Seller Holdback Receivables, and the following assets to the extent deducted in arriving at Net Assets pursuant to Section 2.1(d) above: (i) long term investments, (ii) prepaid deposit — Wichita lease; (iii) certain prepaid insurance, (iv) rolling stock-leased cars and railcar improvements; (v) Citrix information; (vi) other equipment-conveyors; and (vii) building improvements, subject to the assumption by Seller of specified liabilities and obligations, shall be transferred and assumed by Seller at Closing pursuant to the Bill of Sale, Assignment and Satisfaction attached as Exhibit E.

          (b) Discounted Receivables. UBEI or UBES shall remit to Seller on each Monday and Thursday an amount equal to one-half (50%) of the actual amounts collected by UBEI or UBES with respect to the Discounted Receivables after first deducting from such amount any third party costs and expenses of collection incurred by UBEI or UBES with respect to same, provided UBEI or UBES have determined that all amounts collected with respect thereto are good funds. UBEI or UBES may compromise, settle or adjust the amount of the Discounted Receivables without Seller’s prior written consent and shall not be required to undertake any collection efforts not consistent with Buyer’s collection practices for similar account debts owed to Buyer by other third party account debtors and Seller shall not be responsible for any collection costs which Buyer would not have incurred with respect to similar accounts of Buyer. For a period of four months following the Closing Date, Buyer, to the extent permitted by its applicable lenders, shall cause UBEI and UBES to provide read only access to a summary of cash receipts regarding UBEI and UBES (including information such as invoice numbers, amounts, etc.), and if such access is not permitted, will deliver a record of periodic cash receipts delivered by its lender in the form received within one (1) Business Day of receipt Seller shall use such reports for its internal business purposes only and shall treat such information as confidentially and proprietary as it would with respect to its own similar financial information. Upon expiration of the Collection Period, the obligation of UBEI and UBES to continue to exercise collection efforts with respect to the Seller Holdback Receivables shall cease, any Seller Holdback Receivables that have not previously been collected, compromised, or written off shall be deemed uncollectible, and neither UBEI nor UBES shall have any further obligation to remit any portion of said account receivables to Seller in the event amounts are subsequently collected following the expiration of the Ineligible Receivable Earn Out Period.

          (c) Return of Ineligible Receivables. If at any time any portion of the Ineligible Receivables (the “Collected Amount”) is, pursuant to applicable Law, avoided, rescinded or reduced in amount, or must otherwise be restored or returned by UBES or UBEI, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, Seller shall, within five (5) business days of its receipt of notice from Buyer, return to Buyer, UBES or UBEI, as applicable, that portion of the Collected Amount paid to or for the benefit of Seller or any of the Subsidiaries by Buyer, UBES or UBEI hereunder. In the case of US Bio Receivables or Seller Holdback Receivables, Seller shall be entitled to defend against such third-party claims. In the event that Buyer, UBES or UBEI are successful in defending against any such third party claim with respect to the Discounted Receivables

EXECUTION COPY

and thereby prevent any Collected Amount from being avoided, rescinded or reduced in amount, or otherwise restored or returned, Seller shall pay to Buyer, within five (5) business days of its receipt of notice from Buyer, an amount equal to one-half (50%) of the costs and expenses (including attorneys’ and other professionals’ advisor fees) incurred by Buyer, UBES or UBEI in defending such claim, but in no event in excess of the portion of such Collected Amount paid to Seller. If Buyer succeeds in getting any amounts restored, they will be passed on to Seller to the extent of Seller’s interest therein, regardless of whether such restoration falls outside of the Ineligible Receivables Earn Out Period.

     2.5 Blue Ford Earn Out.

          (a) Calculation. The term “Blue Ford Earn Out” means an amount equal to thirty-five percent (35%) of the consolidated after-tax net income (the “Potential Earnout Consideration”) of UBES and UBEI generated solely from the Blue Ford Operations based on operating results for the period from the Effective Date through and including September 30, 2009 (“Earnout Determination Period”), up to an aggregate amount of $1,000,000. Said after-tax net income shall be calculated using GAAP consistently applied (the “Potential Earnout Consideration”), including allocations from Buyer and its Affiliates of selling, general and administrative expenses attributable to the Blue Ford Operations. The Potential Earnout Consideration shall be determined for the period commencing on the Effective Date and ending September 30, 2008, and for the period commencing October 1, 2008 and ending September 30, 2009 (each such period an “Earnout Determination Interval”).

          (b) Payment. As soon as reasonably practical (but in no event more than ninety (90) days) after the expiration of each Earnout Determination Interval, the Buyer shall deliver to the Seller each of the following: (i) the Buyer’s calculation of the Potential Earnout Consideration due the Company for the applicable Earnout Determination Interval; (ii) Buyer’s working papers supporting Buyer’s calculation of the Potential Earnout Consideration for such Earnout Determination Interval; and (iii) a check in the amount of the Potential Earnout Consideration determined by the Buyer. The Buyer shall provide the Seller and its professional advisors with reasonable access during normal working hours to the books and records of UBES and UBEI; provided, however, that access shall be granted only as to such books and records that relate to the Blue Ford Earn Out and are reasonably necessary to enable the Seller to independently verify Buyer’s calculation of the Potential Earnout Consideration for the relevant Earnout Determination Interval. The Seller shall have thirty (30) business days from its receipt from the Buyer of the Potential Earnout Consideration for a specific Earnout Determination Interval to review the Potential Earnout Consideration, and if the Seller disagrees with the Potential Earnout Consideration, submit to Buyer a notice of objection (an “Earnout Consideration Objection Notice”) to the amount of the Potential Earnout Consideration determined by Buyer with respect to the relevant Earnout Determination Interval, describing in reasonable detail the reasoning behind the Seller’s objection to Buyer’s calculation of the Potential Earnout Consideration, including the Seller’s own amount and method of calculation of such Potential Earnout Consideration. Failure to submit an Earnout Consideration Objection Notice within such time period shall be deemed acceptance of the applicable Potential Earnout Consideration. If the Seller objects to the applicable Potential Earnout Consideration within the time period set forth above, Buyer and the Seller shall use commercially reasonable efforts to resolve in good faith any such objection and to agree upon the definitive applicable Potential Earnout Consideration. If within thirty (30) days after Buyer’s receipt of an Earnout Consideration Objection Notice, the parties have not resolved such objections and agreed upon the definitive applicable Potential Earnout Consideration, Buyer and the Company shall engage the Independent Accountant. Buyer and the Company shall cause the Independent Accountant, within forty-five (45) days after its engagement, to resolve such disagreement and to prepare the

EXECUTION COPY

applicable Potential Earnout Consideration, which resolution and definitive applicable Potential Earnout Consideration will be conclusive and binding upon the parties hereto. If the parties submit any unresolved objections to the Independent Accountant for resolution as provided in this Section 2.5(b), the fees and expenses of the Independent Accountant shall be borne equally by both parties.

ARTICLE III

CLOSING

     3.1 Closing and Closing Date. The closing of the sale of the Membership Interest and the Transferred Assets (“Closing”) shall take place at the offices of Moss & Barnett, A Professional Association, 4800 Wells Fargo Center, 90 South Seventh Street, Minneapolis, MN ###-###-#### on the date hereof (“Closing Date”).
