4.2 Authority.

(a) Seller has all requisite corporate power and authority to enter into the Agreement and the agreements and documents relating thereto (the "Transaction Documents") and to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement and the other Transaction Documents and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate action on the part of Seller.

ARTICLE XI

ESCROW AND INDEMNIFICATION

11.1 Survival of Representations, Warranties and Covenants. Notwithstanding any investigation conducted before or after the Closing, and notwithstanding any actual or implied knowledge or notice of any facts or circumstances which Buyer or Seller may have as a result of such investigation or otherwise, Buyer and Seller will be entitled to rely upon the other Party's representations, warranties and covenants set forth in this Agreement. The representations and warranties in ARTICLE IV and ARTICLE V shall survive the Closing as hereinafter provided.

11.2 Indemnification of Buyer. From and after the Closing, and subject to the provisions of Section 11.1, Seller shall indemnify and hold harmless Buyer and its stockholders, directors, officers, employees, affiliates, agents and attorneys (the "Buyer Indemnified Parties") against, and reimbursed for, any actual liability, damage, loss, obligation, demand, judgment, fine, penalty, cost or expense (including reasonable attorneys' fees and expenses, and the costs of investigation incurred in defending against or settling such liability, damage, loss, cost or expense or claim

therefor and any amounts paid in settlement thereof) imposed on or reasonably incurred by the Buyer Indemnified Parties (a) as a result of any breach of any representation, warranty, agreement or covenant on the part of Seller under this Agreement or any of the Transaction Documents, other than breaches of the representations and warranties of Seller included in Section 4.2 (Seller's authority), Section 4.9(a) (title to Purchased Assets) and Section 4.11 (Taxes) and breaches of representations, warranties, agreements and covenants resulting from fraud of Seller (b) as a result of any breach of representations, warranties, agreements and covenants contained in Section 4.2 (Seller's authority), Section 4.9(a) (title to Purchased Assets) and Section 4.11 (Taxes), (c) as a result of any breach of any representation, warranty, agreement or covenant on the part of Seller under this Agreement or any of the Transaction Documents resulting from fraud, (d) arising from any Retained Liabilities or Excluded Assets, and (e) arising out of the ownership or operation of the Purchased Assets or the Seller Business on or prior to the Closing or the distribution or allocation to the securityholders of Seller of any portion of the Purchase Price (collectively the "Buyer Damages"). "Buyer Damages" as used herein is not limited to matters asserted by third parties, but includes Buyer Damages incurred or sustained by a Buyer Indemnified Party in the absence of claims by a third party. Unless otherwise specified herein, the indemnification obligations of Seller under (x) Section 11.2(a), (d) and (e) will survive the Closing and continue in full force and effect until the first anniversary of the Closing Date, (y) Section 11.2(b) shall survive until thirty (30) days after the expiration of the applicable statutes of limitations, and (z) Section 11.2(c) shall survive indefinitely.

11.3 Escrow and Satisfaction of Claims for Buyer Damages.

(a) At the Closing, Buyer will deposit the Escrow Amount and the Warrant with U.S. Bank National Association, as Escrow Agent, such deposit to constitute an escrow fund (the "Escrow Fund") to be governed by the terms set forth herein. The Escrow Fund shall be available to compensate the Buyer Indemnified Parties for any Buyer Damages suffered by them and for any purchase price adjustment determined pursuant to Section 3.4. The Escrow Amount shall be invested at the written direction of the Buyer and the Seller. In the absence of such written direction, funds shall be invested in a U.S. Bank Money Market Account, which is FDIC insured.

(b) Subject to the following requirements, the Escrow Fund shall remain in existence during the period following the Closing for one (1) year (the "Escrow Period"). Upon the expiration of the Escrow Period, and within two (2) business days thereafter, the Escrow Fund shall be released to the Seller, less an amount of property in the Escrow Fund having a value equal to the sum of (i) all amounts theretofore delivered out of the Escrow Fund to the Buyer Indemnified Parties pursuant to this ARTICLE XI, (ii) an amount equal to such portion of the Escrow Fund which, subject to the objection of the Seller and the subsequent arbitration of the matter in a manner consistent with this ARTICLE XI, is necessary to satisfy any unsatisfied claims specified in any Buyer Damages Certificate delivered to the Seller prior to the end of the Escrow Period, and (iii) all amounts delivered out of the Escrow Fund to the Buyer pursuant to Section 11.7, which amount shall remain in the Escrow Fund (and the Escrow Fund shall remain in existence) until such claims have been resolved. As soon as such claims have been resolved (such resolution to be evidenced by the written agreement of Buyer and the Seller or the written decision of the arbitrators as described below), and within two (2) business days thereafter, the Escrow Agent shall deliver to the Seller the

remaining cash and/or Warrant included in the Escrow Fund that are not required to satisfy any remaining claims.

(c) As partial security for the indemnity provided for in Section 11.2 and by virtue of this Agreement, the Escrow Agent shall deliver to a Buyer Indemnified Party an amount of property out of the Escrow Fund having a value equal to the amount of Buyer Damages incurred or sustained by such Buyer Indemnified Party. Any Buyer Damages shall first be satisfied out of the Escrow Fund to the extent of the value of property remaining in the Escrow Fund; provided, however, that the delivery of property out of the Escrow Fund shall not be the Buyer Indemnified Parties' exclusive remedy against Seller for any Buyer Damages incurred or sustained by the Buyer Indemnified Parties, and the Buyer Indemnified Parties may recover any Buyer Damages incurred or sustained by the Buyer Indemnified Parties in excess of the Escrow Fund.

(d) Any Buyer Damages of Buyer may be satisfied, in whole or in part, at the option of the Buyer, by the cancellation of a portion of the Warrant. If the Buyer elects to cancel a portion of the Warrant in satisfaction of any Buyer Damages, the number of shares of Buyer Common Stock to be issued upon exercise of the Warrant (the "Warrant Shares") as of immediately prior to the satisfaction of such Buyer Damages shall be reduced to a number equal to (i) the number of Warrant Shares subject to the Warrant immediately prior to the satisfaction of such Buyer Damages, less (ii) (A) the amount of such Buyer Damages to be satisfied by cancellation of a portion of the Warrant, divided by (B) the Warrant Value Per Share. For purposes of this ARTICLE XI, the value of the Warrant at any time shall equal the maximum number of Warrant Shares issuable upon exercise of such Warrant at such time, multiplied by the Warrant Value Per Share. If a portion of the Warrant is cancelled in satisfaction of any Buyer Damages, the Escrow Agent shall deliver to the Buyer the certificate evidencing the Warrant, upon which Buyer will cancel such certificate and will reissue to the Escrow Agent a certificate representing the right to acquire, upon exercise, such number of Warrant Shares as have not been canceled pursuant to this Section 11.3(d).

(e) In the event that a Buyer Indemnified Party has incurred or sustained Buyer Damages or reasonably anticipates that it will incur or sustain Buyer Damages, such Buyer Indemnified Party shall deliver to Seller and the Escrow Agent (if delivered on or before the expiration of the Escrow Period) a certificate signed by any officer of Buyer (a "Buyer Damages Certificate") (i) stating that the Buyer Indemnified Party has incurred or sustained Buyer Damages or reasonably anticipates that it could incur or sustain Buyer Damages and (ii) specifying in reasonable detail the individual items of Buyer Damages included in the amount so stated, the date each such item was paid, sustained or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant or other indemnity to which such item is related.

(f) Seller shall have twenty (20) days to object to any claim or claims made in a Buyer Damages Certificate. In the event that Seller has not objected within such twenty (20) day period, then (i) as to claims for Buyer Damages made in the Buyer Damages Certificates delivered on or before the expiration of the Escrow Period, the Escrow Agent shall deliver to the Buyer Indemnified Party, on or before ten (10) days after the expiration of such twenty (20) day period, an

amount out of the Escrow Fund equal to the amount set forth in the Buyer Damages Certificate, and (ii) as to claims for Buyer Damages included in the Buyer Damages Certificates delivered after the expiration of the Escrow Period, Seller shall deliver to the Buyer Indemnified Party, on or before ten (10) days after the expiration of such twenty (20) day period, an amount of cash equal to the amount set forth in the Buyer Damages Certificate. In the event that Seller so objects within such twenty (20) day period, such objection must be in the form of a certificate signed by an officer of Seller delivered to Buyer and the Escrow Agent (if applicable) (a "Seller Objection Certificate"), which certificate shall set forth the item or items of Buyer Damages in the Buyer Damages Certificate to which Seller is objecting and a reasonable basis for each such objection.

(g) For a period of fifteen (15) days after the delivery of a Seller Objection Certificate, Buyer and Seller shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If such an agreement is reached as to all or any portion of the Buyer Damages that are subject to the Seller Objection Certificate, then a memorandum setting forth such agreement shall be prepared and signed by both parties and, in the case of a claim against the Escrow Fund, shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum. If no such agreement can be reached after good faith negotiation, either Buyer or Seller may demand arbitration of the matter after the expiration of the fifteen (15) day period set forth in this subsection (g). In such event, the matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to Buyer and Seller. In the event that, within fifteen (15) days after submission of any dispute to arbitration, Buyer and Seller cannot mutually agree on one arbitrator, then, within ten (10) days after the end of such fifteen (15) day period, Buyer and Seller shall each select one arbitrator. The two arbitrators so selected shall select an arbitrator to conduct the arbitration.

(h) Any such arbitration shall be held in Delaware under the rules then in effect of the American Arbitration Association. The arbitrator shall determine how all expenses relating to the arbitration shall be paid, including without limitation, the respective expenses of each party, the fees of the arbitrator and the administrative fee of the American Arbitration Association. The arbitrator shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrator, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrator shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys' fees and costs, to the same extent as a competent court of law or equity, should the arbitrator determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of the arbitrator as to the validity and amount of any claim in a Buyer Damages Certificate shall be final, binding, and conclusive upon the parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator. Within thirty (30) days after a decision of the arbitrator requiring payment by one party to another, such party shall make the payment to such other party.

(i) Judgment upon any award rendered by the arbitrator may be entered in any court having jurisdiction. The forgoing arbitration provision shall apply to any dispute between Buyer Indemnified Party and Seller under this ARTICLE XI.

11.4 Indemnification of Seller; Satisfaction of Claims for Seller Damages.

(a) From and after the Closing, and subject to the provisions of Section 11.1, Buyer shall indemnify and hold harmless Seller and its stockholders, directors, officers, employees, affiliates, agents and attorneys (the "Seller Indemnified Parties") against, and reimbursed for, any actual liability, damage, loss, obligation, demand, judgment, fine, penalty, cost or expense (including reasonable attorneys' fees and expenses, and the costs of investigation incurred in defending against or settling such liability, damage, loss, cost or expense or claim therefor and any amounts paid in settlement thereof) imposed on or reasonably incurred by the Seller Indemnified Parties (i) as a result of any breach of any representation, warranty, agreement or covenant on the part of Buyer under this Agreement or any of the Transaction Documents, (ii) arising from any Assumed Liabilities, including the obligations under the Assumed Contracts, but excluding any liability or obligation arising out of or relating to a breach of or default under an Assumed Contract that occurred on or before the Closing, and excluding any liability or obligation arising out of or related to a breach of a representation, warranty or covenant of Seller under this Agreement or the Transaction Documents, and (iii) to the extent it arises exclusively out of the ownership or operation of the Purchased Assets or the Seller Business after the Closing (collectively the "Seller Damages"). "Seller Damages" as used herein is not limited to matters asserted by third parties, but includes Seller Damages incurred or sustained by a Seller Indemnified Party in the absence of claims by a third party. Unless otherwise specified herein, the indemnification obligations of Buyer under this Section 11.4 will survive the Closing and continue in full force and effect until the first anniversary of the Closing Date.

(b) In the event that a Seller Indemnified Party has incurred or sustained Seller Damages or reasonably anticipates that it will incur or sustain Seller Damages, such Seller Indemnified Party shall deliver to Buyer a certificate signed by any officer of Seller (a "Seller Damages Certificate") (i) stating that the Seller Indemnified Party has incurred or sustained Seller Damages or reasonably anticipates that it could incur or sustain Seller Damages and (ii) specifying in reasonable detail the individual items of Seller Damages included in the amount so stated, the date each such item was paid, sustained or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant or other indemnity to which such item is related. Buyer shall have twenty (20) days to object to any claim or claims made in a Seller Damages Certificate. In the event that Buyer has not objected within such twenty (20) day period, then Buyer shall deliver to the Seller Indemnified Party, on or before ten (10) days after the expiration of such twenty (20) day period, an amount of cash equal to the amount set forth in the Seller Damages Certificate. In the event that Buyer so objects within such twenty (20) day period, such objection must be in the form of a certificate signed by an officer of Buyer delivered to Seller (a "Buyer Objection Certificate"), which certificate shall set forth the item or items of Seller Damages in the Seller Damages Certificate to which Buyer is objecting and a reasonable basis for each such objection.

(c) For a period of fifteen (15) days after the delivery of a Buyer Objection Certificate, Seller and Buyer shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If such an agreement is reached as to all or any portion of the Seller Damages that are subject to the Buyer Objection Certificate, then a memorandum setting forth such agreement shall be prepared and signed by both parties. If no such agreement can be reached after good faith negotiation, either Seller or Buyer may demand arbitration of the matter after the expiration of the fifteen (15) day period set forth in this subsection (c). In such event, the matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to Seller and Buyer. In the event that, within fifteen (15) days after submission of any dispute to arbitration, Seller and Buyer cannot mutually agree on one arbitrator, then, within ten (10) days after the end of such fifteen (15) day period, Seller and Buyer shall each select one arbitrator. The two arbitrators so selected shall select an arbitrator to conduct the arbitration. Any such arbitration shall be held in Delaware under the rules then in effect of the American Arbitration Association. Such arbitration shall be conducted in accordance with Section 11.3(h). The decision of the arbitrator as to the validity and amount of any claim for Seller Damages shall be final, binding, and conclusive upon the parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator. Within thirty (30) days after a decision of the arbitrator requiring payment by one party to another, such party shall make the payment to such other party. Judgment upon any award rendered by the arbitrator may be entered in any court having jurisdiction. The forgoing arbitration provision shall apply to any dispute between Seller Indemnified Party and Buyer under this ARTICLE XI.

11.5 Third Party Claims. In the event either any Buyer Indemnified Party or Seller Indemnified Party (an "Indemnified Party") becomes aware of a third party claim that the Indemnified Party reasonably believes may result in a demand for indemnification, the Indemnified Party shall notify Seller or the Buyer, as applicable (the "Indemnifying Party") of such claim, and the Indemnifying Party shall be entitled, at their expense, to participate in, but not to determine or conduct, the defense of such claim. The Indemnified Party shall have the right in its sole discretion to conduct the defense of and settle any such claim; provided, however, that except with the consent of the Indemnifying Party, no settlement of any such claim with third party claimants shall be determinative of the amount of Buyer Damages or Seller Damages, as the case may be, relating to such matter. In the event the Indemnifying Party has consented to any such settlement, the Indemnifying Party shall have no power or authority to object under any provision of this ARTICLE XI to the amount of any claim by the Indemnified Party with respect to such settlement.

11.6 Maximum Liability; Basket. Notwithstanding anything to the contrary contained herein, (i) Seller's aggregate indemnification obligation under Section 11.2, other than its indemnification obligations under Section 11.2(c), shall never exceed the sum of (A) $10,500,000 and (B) the value of the Warrant as of the Closing, (ii) Seller's aggregate indemnification obligation under Section 11.2(c) shall be without limit, (iii) the Buyer Indemnified Parties shall not be entitled to indemnification for Buyer Damages under Sections 11.2(a), (b), (d) and (e) unless the aggregate amount of such Buyer Damages equals or exceeds $200,000 (the "Basket Amount"), in which case the Buyer Indemnified Parties shall be entitled to the entire amount of such Buyer Damages including Buyer Damages covered by the Basket Amount, (iv) Buyer's aggregate indemnification

obligation under Section 11.4 shall never exceed the sum of (A) $10,500,000 and (B) the value of the Warrant as of the Closing, and (v) the Seller Indemnified Parties shall not be entitled to indemnification for Seller Damages under Sections 11.4 unless the aggregate amount of such Seller Damages equals or exceeds the Basket Amount, in which case the Seller Indemnified Parties shall be entitled to the entire amount of such Seller Damages including Seller Damages covered by the Basket Amount.

11.7 Purchase Price Adjustment. Any amounts due to Buyer under Section 3.4 shall be paid to Buyer out of the Escrow Fund. Upon determination of the amount of all claims against Seller for reimbursement under Section 3.4, Buyer and Seller shall deliver to Escrow Agent written instructions, signed by each Buyer and Seller, as to the amount of property to be delivered to Buyer pursuant to this Section 11.7.

11.8 Escrow Agent's Duties.

(a) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth in this Agreement and as set forth in any additional written escrow instructions which the Escrow Agent may receive after the date of this Agreement which are signed by an officer of Buyer and an officer of Seller, and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow Agent while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith.

(b) The Escrow Agent shall hold and safeguard the Escrow Fund during the Escrow Period, shall treat such funds as trust funds in accordance with the terms of this Agreement and not as property of Buyer, and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof.

(c) The Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person, excepting only orders or process of courts of law, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(d) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder.

(e) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent.

(f) The Escrow Agent may resign as Escrow Agent at any time with or without cause by giving at least thirty (30) days' prior written notice to each of Buyer and Seller, such resignation to be effective thirty (30) days following the date such notice is given. In addition, Buyer and Seller may jointly remove the Escrow Agent as escrow agent at any time with or without cause, by an instrument (which may be executed in counterparts) given to the Escrow Agent, which instrument shall designate the effective date of such removal. In the event of any such resignation or removal, a successor escrow agent which shall be a bank or trust company organized under the laws of the United States of America or any state thereof having a combined capital and surplus of not less than $100,000,000, shall be appointed by Buyer with the approval of Seller, which approval shall not be unreasonably withheld. Any such successor escrow agent shall deliver to Buyer and Seller a written instrument accepting such appointment, and thereupon it shall succeed to all the rights and duties of the Escrow Agent hereunder and shall be entitled to receive the Escrow Fund. Thereafter, the predecessor Escrow Agent shall be discharged for any further duties and liabilities under this Agreement.

(g) In performing any duties hereunder, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except for gross negligence, bad faith or willful misconduct on the part of the Escrow Agent. The Escrow Agent shall not incur any such liability for any action taken or omitted in reliance upon any instrument, including any written statement or affidavit provided for in this Agreement that the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow Agent be liable or responsible if acting in good faith for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with the legal counsel in connection with Escrow Agent's duties under this Agreement and shall be fully protected in any act taken, suffered, or permitted by it in good faith in accordance with the advice of counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any Party to this Agreement.

(h) If any controversy arises between the Parties to this Agreement, or with any other Party, concerning the subject matter of this Agreement, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent shall await the arbitrators' decision as specified in Section 11.3(h), and act to make or withhold payments out of the Escrow Fund in accordance with such decision.

(i) Buyer and Seller and their respective successors and assigns shall, jointly and severally, indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, counsel fees, and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of its duties under this Agreement.

11.9 Escrow Agent Fees. All fees of the Escrow Agent for performance of its duties hereunder shall be paid by Buyer in accordance with the standard fee schedule of the Escrow Agent.
