NOW, THEREFORE, in consideration of the premises and of the mutual agreements, covenants, representations and warranties contained herein, the parties, intending to be legally bound, agree as follows:

1. Purchase and Sale of Assets; Assumption of Liabilities.

1.1 Subject to and upon the terms and conditions set forth in this Agreement, at the Closing, Buyer agrees to purchase from Seller and Seller agrees to sell, transfer, convey, assign and deliver to Buyer (at Seller’s premises) all of the Acquired Assets, in each case free and clear of all Encumbrances of any kind.

1.2 Notwithstanding anything contained in this Agreement, Seller shall not sell, transfer, assign, convey or deliver to Buyer, and Buyer shall not purchase or acquire from Seller, any of Seller’s cash or accounts receivable, or any assets of Seller other than the Acquired Assets.

1.3 Subject to and upon the terms and conditions of this Agreement, at the Closing, Buyer agrees to assume, and shall thereafter pay, fulfill, perform and otherwise discharge, only the Assumed Liabilities. Buyer shall not assume or take title to the Acquired Assets subject to, or in any way be liable or responsible for, any Liability of Seller or the Business that is not an Assumed Liability (the “Excluded Liabilities”) and Seller shall pay, fulfill, perform and discharge such Excluded Liabilities when due.

2. Purchase Price and Payment. In consideration for the purchase of the Acquired Assets, Buyer shall pay to Seller an amount in cash equal to ten million nine hundred thousand ($10,900,000) dollars (the “Purchase Price”), subject to adjustment as provided below, as follows:

(a) At the Closing, Buyer shall pay to Seller, by wire transfer of immediately available funds to such bank account as shall be designated in writing by Seller, an amount in cash equal to five million nine hundred thousand ($5,900,000) dollars (the “Initial Payment”). Notwithstanding the foregoing, the Initial Payment shall be adjusted, on a dollar for dollar basis, by the amount by which the value of the Inventory on the Inventory Date is either greater or less than nine hundred thousand ($900,000) dollars. Following the Closing, Buyer shall pay to Seller an additional amount (the “Additional Payment”) determined as set forth in Sections 2(b) and 2(c) below.

(b) Within fifteen (15) days of the end of each of the first eleven (11) fiscal months of the Post-Closing Period (defined below), Buyer shall deposit into an independent third party escrow account (the “Escrow Account”) maintained at U.S. Bank N.A. (the “Escrow Agent”), as further provided in an Escrow Agreement to be entered into by BioScrip, Buyer, Seller and the Escrow Agent (the “Escrow Agreement”), an amount (the “Monthly Escrow Payment”) to be determined by multiplying (i) $400,000 by (ii) a fraction, the numerator of which is equal to the Gross Profit of the Business achieved during such fiscal month (calculated in the manner set forth on Schedule 2(b) hereto) and the denominator of which is the Gross Profit of the Business for the same fiscal month in the Pre-Closing Period (calculated in the manner set forth on Schedule 2(b) hereto); provided that the maximum amount to be deposited into the Escrow Account for any fiscal month shall not exceed $400,000. In addition, each Monthly Escrow Payment shall be adjusted such that the cumulative amount in the Escrow Account reflects the amount due based on the cumulative Gross Profit of the Business through the most recent fiscal month-end.

(c) On the Escrow Release Date, Buyer shall deliver or cause to be delivered to Seller an amount in cash (the “Final Payment”) equal to (i) five million ($5,000,000) dollars multiplied by a fraction, the numerator of which is equal to the Gross Profit of the Business during the first full twelve (12) fiscal months beginning with the first full fiscal month following the fiscal month in which the Closing Date occurs (such amount, the “Post-Closing Gross Profit,” and such twelve-month period, the “Post-Closing Period”) and the denominator of which is the Gross Profit of the Business during the full twelve fiscal months ending with the fiscal month immediately prior to the fiscal month in which the Closing Date occurs (the “Pre-Closing Gross Profit”) less (ii) all funds deposited into the Escrow Account by or on behalf of Buyer prior to the Escrow Release Date. Gross Profit shall be calculated in the manner set forth on Schedule 2(b). The Final Payment shall be paid by wire transfer of immediately available funds to such bank account as shall be designated in writing by Seller.

(d) BioScrip will cause the funds in the Escrow Account to be paid to the Company on or before the date that is fourteen (14) months from the Closing Date (the “Escrow Release Date”). For the avoidance of doubt, as a result of the adjustments set forth in Section 2(c), the aggregate Purchase Price may be greater or less than $10.9 million.

(e) Not less than ten (10) Business Days prior to the Escrow Release Date, Buyer shall provide Seller with a certificate (the “Escrow Payment Certificate”) signed by the Buyer that sets forth Buyer’s calculation of each Monthly Escrow and the Final Payment amount (the “Escrow Payments”). The calculation of the Escrow Payments shall be prepared using the Gross Profit of the Business calculated in the manner set forth on Schedule 2(b) hereto. Buyer shall provide Seller and its accountants with reasonable access (for a period of not more than sixty (60) days after receipt by Seller of the statement setting forth Buyer’s calculation of the Escrow Payments) to the work papers and other documents prepared by, or on behalf of, Buyer relating to the preparation and calculation thereof for the purpose of reviewing and determining whether to accept or dispute Buyer’s calculation of the amount of

the Escrow Payments. If Seller does not dispute Buyer’s calculation of the amount of the Escrow Payments in writing within sixty (60) calendar days after delivery of the Final Payment amount, the amount of the Final Payment as calculated by Buyer shall be final, conclusive and binding as the Final Payment hereunder on all of the parties hereto. If Seller disputes Buyer’s calculation of the amount of the Escrow Payments, it shall so notify Buyer in writing within sixty (60) calendar days after delivery of the certificate setting forth the calculation of the amount of the Escrow Payments, specifying its objections and the reasons therefor in reasonable detail (the “Objection Notice”). Notwithstanding the delivery of an Objection Notice by Seller, Buyer shall deliver or cause to be delivered the Final Payment as set forth in the Escrow Payment Certificate to Seller no later than the date that is fourteen (14) months from the Closing Date. If Seller delivers an Objection Notice, Buyer and Seller shall use reasonable efforts to resolve the dispute as expeditiously as possible. If the dispute is not resolved within twenty (20) calendar days after delivery of the Objection Notice, such dispute shall be submitted to an accounting firm of national reputation mutually agreed upon by Buyer and Stockholder) (the “Accounting Referee”) with a request to resolve the dispute and deliver its report thereon to Buyer and Seller within thirty (30) calendar days of its appointment. The fees and expenses of the Accounting Referee shall be shared equally by Buyer and Seller.

(f) The difference between the aggregate amount of the Escrow Payments as set forth in the Escrow Payment Certificate and the amount finally determined pursuant to Section 2(e) following delivery of an Objection Notice shall be paid to Seller no later than five (5) Business Days following the resolution of the dispute.

(a) The Indemnitee shall give prompt notice (the “Claim Notice”) to the Indemnifying Party of any claim, including any claim, action, suit, proceeding or investigation by a third party (a “Third Party Claim”), that may result in a Loss. Subject to Section 9.2, the failure to deliver a Claim Notice shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the resulting delay is materially prejudicial to the defense of any such claim. The Claim Notice shall describe the claim in detail, and shall indicate the amount (estimated, if necessary) of the Loss that has been or may be suffered by the Indemnitee.

(b) If the claim set forth in the Claim Notice involves a Third Party Claim, the Indemnifying Party will have the right to assume (subject to the limitations of this Section 9) and thereafter conduct the defense of such Third Party Claim with counsel of its choice (and reasonably acceptable to the Indemnitee) if it acknowledges to the Indemnitee in writing its obligation to indemnify the Indemnitee with respect to all elements of such Third Party Claim; provided, that the Indemnifying Party shall exercise its right to assume such defense within fifteen (15) days of its receipt of the Claim Notice and the Indemnifying Party provides the Indemnitee with evidence reasonably acceptable to the Indemnitee that the Indemnifying Party will have the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder. If the Indemnifying Party assumes the

defense of the Indemnitee in accordance with the provisions hereof, it shall conduct such defense of the Third Party Claim actively and diligently. If the Indemnifying Party does not assume the defense of a Third Party Claim, the Indemnitee may defend such Third Party Claim in such manner as it deems appropriate.

(c) If the Indemnifying Party assumes the defense of any Third Party Claim, the Indemnitee shall be entitled to participate in but not control the defense of such Third Party Claim with its own counsel and at its own cost and expense; provided, however, that if the Indemnitee asserts that there exists a conflict of interest that would make it inappropriate for the same counsel to represent both the Indemnitee and the Indemnifying Party, then the Indemnifying Party shall reimburse the Indemnitee for the reasonable fees and expenses of separate counsel, to the extent such fees and expenses are incurred solely in connection with the matters with respect to which there is a conflict of interest. Notwithstanding anything in this Section 9.3 to the contrary, in no event shall any party, without the written consent of the other party; (i) settle or compromise any Third Party Claim or consent to the entry of any judgment that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the other party of a written release from all liability in respect of such Third Party Claim; or (ii) settle or compromise any Third Party Claim in any manner that (A) involves the sale, forfeiture or loss of, or the creation of any Encumbrance on, any property of such other party, (B) involves an award that together with previous awards would exceed the available amount of the indemnity hereunder, or (C) involves equitable remedies against such other party or any of its Affiliates.

(d) All parties hereto shall cooperate reasonably in the defense of any Third Party Claim and shall use its reasonable efforts to furnish all witnesses and testimony, records, materials and other information, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested in connection therewith.

(e) If the claim set forth in a Claim Notice does not involve a Third Party Claim, the Indemnifying Party shall notify the Indemnitee within sixty (60) days of its receipt of the Claim Notice whether or not the Indemnifying Party disputes such claim. If the Indemnifying Party does not timely notify the Indemnitee that it disputes such claim, as provided above, the claim specified by the Indemnitee in the Claim Notice will be deemed a Liability of the Indemnifying Party hereunder. If the Indemnifying Party timely disputes such claim, such dispute will be resolved by litigation in an appropriate court of competent jurisdiction.

9.4 Limitations.

(a) Losses in respect of which an Indemnifying Party is required to make indemnification under Section 9.1 shall be reduced by an amount equal to any insurance, indemnity, contribution or other similar payments actually paid to and received by the applicable Indemnitee from any third party with respect to any claim giving rise to the Losses. If any insurance, indemnity, contribution or other similar payments are paid to or received by any Indemnitee in a period after such Losses are incurred or indemnification in respect thereof is made, such Indemnitee shall promptly notify the Indemnifying Party and pay the Indemnifying Party an amount equal to such insurance benefits.

(b) Losses in respect of which Seller and Stockholder are required to indemnify a Buyer Indemnified Party shall be reduced by the amount of all or any portion of the Additional Payment that has not been paid to Seller (including amounts then held in the Escrow Account) as of the date of the Claim Notice in respect of which indemnification is sought and which amounts shall be retained by Buyer as an offset.

(c) In no event shall Stockholder’s and Seller’s combined, aggregate obligations, on the one hand, or Buyer’s aggregate obligations, on the other hand, exceed the amount of Purchase Price.

(d) Neither the Buyer Indemnified Parties nor the Seller Indemnified Parties shall be entitled to indemnification for any Losses unless and until such time as the cumulative aggregate amount of all indemnifiable Losses payable to such Indemnitee exceeds one hundred thousand dollars ($100,000), at which time the Indemnitee shall be entitled to recover the amount of all indemnifiable Losses.
