BACKGROUND

A. Borrowers, Lenders, and Agent are parties to a certain Loan and Security Agreement dated as of May 18, 2011 (as amended or modified from time to time, the “Loan Agreement”). Capitalized terms used but not otherwise defined in this Amendment shall have the meanings respectively ascribed to them in the Loan Agreement.

B. Borrowers have requested and Agent and Lenders have agreed to amend the Loan Agreement in certain respects, all on the terms and conditions set forth herein.

NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby promise and agree as follows:

1. Amendments. Upon the effectiveness of this Amendment, the Loan Agreement is amended as follows:

(a) Definitions. The following definitions contained in Section 1.1 of the Loan Agreement are amended and restated as follows:

“Advance Rate” means the following percentage based upon the Collateral Performance Indicator as of the end of each month then most recently ended for which monthly reports have been delivered to Agent, pursuant to Section 6.2:

“Applicable Margin” means Four and One Quarter of One Percent (4.25%).

“Maturity Date” means May 18, 2015.

(b) Eligible Receivables. Clause (h) of the definition of Eligible Receivables contained in Section 1.1 of the Loan Agreement is amended and restated as follows:

(h) Receivables with a remaining balance in excess of (i) Ten Thousand One Hundred Dollars ($10,100) for Health Services Receivables and Specialty Bed Receivables, and (ii) Seven Thousand Five Hundred Dollars ($7,500) for Home Exercise Equipment Receivables;

(c) Prepayments. Section 2.8(a) of the Loan Agreement is amended and restated as follows:

(a) Optional Prepayments. Borrowers may prepay the Loan from time to time, in full or in part not to exceed Five Million Dollars ($5,000,000) without notice, and, in part, in excess of Five Million Dollars ($5,000,000) upon Seven (7) Business Day’s prior notice to Agent without premium or penalty, provided that (i) in the event Borrowers repay the Loan in full or the Obligations are accelerated following the occurrence of an Event of Default at any time prior to the Maturity Date, Borrowers shall pay a sum equal to One and One Half of One Percent (1.5%) of the Maximum Principal Amount as a prepayment fee, (ii) prepayments shall be in a minimum amount of Ten Thousand Dollars ($10,000) and Ten Thousand Dollars ($10,000) increments in excess thereof; and (iii) partial prepayments prior to the Termination Date shall not reduce Lenders’ Commitments under this Agreement and may be reborrowed, subject to the terms and conditions hereof for borrowing, and partial prepayments will be applied first to accrued interest and fees and then to outstanding Advances. Each Borrower acknowledges that the above described fee is an estimate of Lenders’ damages in the event of early termination and is not a penalty. In the event of termination of the credit facility established pursuant to this Agreement, all of the Obligations shall be immediately due and payable upon the termination date stated in any notice of termination. All undertakings, agreements, covenants, warranties and representations of Borrowers contained in the Credit Documents shall survive any such termination, and Agent shall retain its liens in the Collateral and all of its rights and remedies under the Credit Documents notwithstanding such termination until Borrowers have paid the Obligations to Agent and Lenders, in full, in immediately available funds, together with the applicable termination fee, if any. Notwithstanding the foregoing, in the event any Borrower should enter into a Change of Ownership transaction acceptable to Lenders (as determined in their sole and absolute discretion) and Lenders enter into a modified or new financing with the acquiring Person or Lenders otherwise consents to such Change in Ownership in writing, then the termination fee shall be waived by Lenders.

(i) Principal Receivables for the most recent month end multiplied by the rolling twelve (12) month ratio of net charge-offs to average Principal Receivables during such twelve (12) month period;

(ii) Thirteen Percent (13.0%) of Principal Receivables;

(iii) an amount pursuant to the recommendation of the independent certified public accountant auditing Borrowers’ financial statements.

(e) Collateral Performance Indicator. Section 6.4(e) of the Loan Agreement is amended and restated as follows:

(e) Collateral Performance Indicator. A Collateral Performance Indicator of less than or equal to Twenty Nine Percent (29%).

(f) Arbitration. The parties hereto agree and acknowledge that all jurisdiction, venue and jury trial provisions contained in the Credit Documents are replaced with the following arbitration provision:

(i) Arbitration. The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to (i) this document, any credit subject hereto, or any of the Credit Documents, and their negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests for additional credit.

(ii) Governing Rules. Any arbitration proceeding will (i) proceed in a location in Iowa selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the

3

parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(iii) No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration requirement does not limit the right of any party to (A) foreclose against real or personal property collateral; (B) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (C) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sub-clauses (A), (B) and (C) of this clause (iii).

(iv) Arbitrator Qualifications and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000. Any dispute in which the amount in controversy exceeds $5,000,000 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in the State of Iowa or a neutral retired judge of the state or federal judiciary of Iowa, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in

4

accordance with the substantive law of Iowa and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Iowa Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

(v) Discovery. In any arbitration proceeding, discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than twenty (20) days before the hearing date. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party’s presentation and that no alternative means for obtaining information is available.

(vi) Class Proceedings and Consolidations. No party hereto shall be entitled to join or consolidate disputes by or against others in any arbitration, except parties who have executed this document or any other Credit Document, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of the general public or in a private attorney general capacity.

(vii) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration proceeding.

(viii) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within one hundred eighty (180) days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to this document and the Credit Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of this document and the other Credit Documents or any relationship between the parties.
