THIS PURCHASE AND SALE AGREEMENT (“Agreement”) is made as of November 19, 2003 by and between Lifeline Systems, Inc. (hereinafter “Seller”), a Massachusetts corporation with a principal place of business at 111 Lawrence Street, Framingham, MA 01702 and De Lage Landen Financial Services, Inc. (hereinafter “Purchaser”), a Michigan corporation with a principal place of business at 1111 Old Eagle School Road, Wayne, Pennsylvania 19087.

WITNESSETH:

WHEREAS, Seller has, in its ordinary course of business, entered into lease agreements (each a “Contract” and collectively, “Contracts”) directly with lessees (each an “Obligor” and collectively, “Obligors”) for the lease of the equipment (“Equipment”) listed therein and as such Contracts are more fully described on Schedule A attached hereto and made a part hereof; and

WHEREAS, Seller has agreed to sell and assign to Purchaser and Purchaser has agreed to purchase and accept the assignment of all of Seller’s right, title and interest in, to and under the Contracts listed on Schedule A and all payments coming due thereunder; and

NOW, THEREFORE, in consideration of the agreements and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

I. ASSIGNMENT AND PURCHASE

1.1 Agreement to Sell. Subject to the terms and conditions set forth herein, upon Purchaser’s payment to Seller of the purchase price of One Million Six Hundred Twenty-Five Thousand Four Hundred Forty-Four Dollars and Seventy-Two Cents ($1,625,444.72) (“Purchase Price”), Seller will, and hereby does without further action:

all by executing an assignment in the form annexed hereto as Exhibit A, which is made a part hereof (the “Assignment”).

Purchaser shall have, in addition to all other rights hereunder, the right to (i) receive and retain any and all

Payments and rights thereto under any Contract; (ii) use or sell or dispose of Equipment (subject to Obligor’s interest therein); and (iii) apply and use such Payments, rights, Equipment (subject to Obligor’s interest therein) and proceeds to satisfy any and all obligations of Seller hereunder.

The parties hereto intend the sale, assignment and transfer of each Contract by Seller to Purchaser hereunder to be a true sale thereof, and not a loan secured by the granting of a lien thereon. If, notwithstanding the foregoing, any transaction of which the sale, assignment and transfer is a part is construed by a court of competent jurisdiction to be a loan and not a true sale and, in addition, as security for all of Seller’s obligations to Purchaser under this Agreement, and for Obligors’ respective obligations under the Contracts, Seller hereby grants and assigns, as applicable, to Purchaser to the extent not transferred a first priority security interest prior in right to all persons and entities (other than that of Obligor under the Contract) in and to all of the following, whether now or in the future owned by Seller:

Upon the occurrence of a default under any Contract, Purchaser shall be entitled to exercise all rights and remedies available to it as a secured party under all applicable laws, including, without limitation, the Uniform Commercial Code (“UCC”), and all rights and remedies under the Contract.

1.2 No Assumption by Purchaser. Purchaser does not assume any of Seller’s, vendor’s or other obligations under any Contract or with respect to any Equipment and shall have no duties in respect thereof, and, in this regard, Seller shall indemnify, defend and hold Purchaser harmless against any and all claims, liabilities or actions with respect thereto.

1.3 Conditions Precedent. Purchaser shall pay the Purchase Price upon Purchaser’s receipt of the following: (a) a duly executed copy of this Agreement; (b) a duly executed Assignment from Seller; (c) the originals of all Contracts (with guarantees or other surety therefor, if any, and all related documents) identified on Schedule A hereto and to the Assignment; (d) a Secretary’s Certificate of Seller with specimen signatures, substantially in the form of Exhibit B hereto; and (e) UCC-1 financing statement against Seller with Purchaser as Secured Party with respect to the Contracts sold and assigned hereunder and Equipment subject thereto.

1.4 Servicing. Upon payment of the Purchase Price, the parties agree that Purchaser (in the name of Seller pursuant to Section 6.2) shall commence billing and collecting of all Payments and other amounts coming due under each Contract as of January 1, 2004. Purchaser shall also bill and collect, on behalf of Seller, all property taxes owing with respect to any Equipment subject to a Contract. Seller shall provide Purchaser with an invoice indicating the amount of such property taxes to be billed by Purchaser. Purchaser shall have no liability for any property taxes owing with respect to any Equipment and Seller hereby agrees to indemnify, defend and hold Purchaser harmless from and against any and all Losses (as defined in Section 4) related to such taxes

(including without limitation any fines, interest and penalties related thereto). Further, Purchaser shall bill and collect all sales taxes owing with respect to any Equipment at a rate determined by Purchaser and Purchaser shall remit such sales taxes to the appropriate taxing authorities in Purchaser’s name. In the event Purchaser collects a Payment that is less than the total Payment, taxes and other amounts owing under a Contract, the amount so collected shall be applied as follows: first, to Purchaser for any past due Payments and other amounts owing under the Contract (including any past due sales tax) and second, for payment of property taxes.

In the event Seller receives any Payments with respect to any Contract that belong to Purchaser pursuant to this Agreement, Seller agrees that such Payments will be Purchaser’s property and will be held in trust by Seller for Purchaser. Seller shall, on a twice monthly basis, but in no event later than 1 day prior to the last business day of the month remit any such Payments to Purchaser via ACH. If Seller fails to remit any Payments it collects to Purchaser pursuant to this paragraph, Seller shall pay Purchaser interest on such Payment at ten percent (10%) per annum until paid.

(i) Upon the occurrence of an Event of Default as defined in a Contract or (ii) in the event Seller shall file or have filed against it any action for relief under any existing or future law relating to bankruptcy, insolvency, reorganization or relief of debtors, a receiver is appointed for Seller, Seller makes a general assignment for the benefit of its creditors, Seller shall generally not, or be unable to, pay its debts as they come due, or Seller shall dissolve, Purchaser shall have the option to notify the Obligor of the transfer and assignment of the Contract by sending the Obligors a notice letter pursuant to Section 6.2 of this Agreement. Such notice letter shall be in such form as Purchaser deems reasonably necessary to effectuate the terms of this paragraph. Upon sending any notice letter, Purchaser may thereafter conduct all future activities with respect to the Contract (including, without limitation, billing and collecting all Payments due thereunder) in its own name and not under the name of Seller.

In addition to the services provided above, Purchaser agrees to assist Seller in billing and collecting past due payments that may be owing to Seller under contracts not assigned to Purchaser under this Agreement but which contracts are with a customer that is also an Obligor under a Contract assigned to Purchaser under this Agreement. The parties shall mutually agree on the processes to be followed by Purchaser with respect to such collection activities. In the event Purchaser bills and collects any such past due amounts owing to Seller from a customer that is also an Obligor under a Contract assigned to Purchaser under this Agreement, any amounts actually collected by Purchaser from such Obligor shall be applied as follows: first, to Purchaser for any past due Payments and other amounts owing under Purchaser’s Contract (including any late charges and past due sales tax) and second, to Seller. Purchaser shall, on a twice monthly basis, (but in no event later than 1 day prior to the last business day of the month) remit any such Payments to Seller via ACH.

3.2 Intentionally Omitted.

3.3 Post-Closing Review. The parties acknowledge and agree that Purchaser may not have originals of all Contract documentation and/or have completed its documentation review with respect to the Contracts identified on Schedule A as of the date of payment of the Purchase Price.

Seller’s portion shall be [**] percent ([**]%) of such payments collected and Purchaser’s portion shall be [**] percent ([**]%) of such payments collected.
