4.21. Business as a Going Concern. Seller is hereby transferring the Assets to Purchaser with the intent to transfer to Purchaser the Business of Seller, as the same existed immediately prior to the Closing Date, as a going concern.

5. WARRANTIES OF PURCHASER. To induce Seller to enter into and perform under this Agreement, Purchaser hereby warrants to Seller:

5.1. Good Standing and Authority. Purchaser is a corporation duly organized, validly existing and in good standing under the laws of England and Wales.

This Agreement and all of the Attendant Documents to which Purchaser is a party, and the consummation of the transactions contemplated in this Agreement, have been or will be, on or prior to the Closing Date, duly authorized and approved by all necessary and proper corporate action on the part of Purchaser. This Agreement, and all of the Attendant Documents to which Purchaser is a party, as the case may be, when executed and delivered, will constitute legal, valid and binding obligations of Purchaser enforceable against Purchaser in accordance with their respective terms.

5.2. Non-Violative Agreement. Neither the execution and delivery of this Agreement and the Attendant Documents to which Purchaser is a party nor the consummation of the transactions contemplated in this Agreement will conflict with, result in the breach or violation of or constitute a default under the terms, conditions or provisions of either Purchaser’s organizational documents or any other agreement or instrument to which Purchaser is a party, or by which Purchaser is bound or to which it is subject.

5.3. Brokerage or Finder’s Fee. No broker, finder, agent or similar intermediary has acted for or on behalf of Purchaser in connection with this Agreement or the transactions contemplated hereby and no broker, finder, agent or similar intermediary is entitled to any broker’s, finder’s or similar fee or other commission in connection therewith based on any agreement, arrangement or understanding with Purchaser or any action taken by Purchaser.

5.4 Conduct of the Business. From and after the Closing Date, the Purchaser shall use its commercially reasonable endeavors to use and employ the Assets to conduct the Business as a going concern.

6. ADDITIONAL AGREEMENTS AND COVENANTS; SURVIVAL.

6.1. Use of Seller’s Name. In partial consideration of the Purchase Price, at Closing, the Seller is transferring to Purchaser and Purchaser is receiving, the right to use

the name and trademark “BioRobotics,” subject to the terms and provisions of the Co-Existence Agreement, which Purchaser is executing and delivering at Closing as an express condition of such transfer of right.

6.2. Employees. From and after the Closing Date, the Purchaser shall: (a) perform and observe all the employer’s obligations, whether under the contract of employment or otherwise, arising out of or in connection with any Employees’ employment including, without limitation, payment for wages or salaries, accrued holiday pay, sick pay, maternity pay, liability to tax, accrued bonuses or commissions and other periodic payment for any period after the Closing Date; and (b) perform and observe all the transferee’s obligations arising under Regulation 10 of TUPE, including but not limited to providing the Seller with such information as it requests prior to the Closing Date in order to allow it to perform its own obligations under Regulation 10(2) and Regulation 10(3) and its obligations arising under section 188 of TULCRA. Prior to the last day of the ninth month after the Closing Date, Purchaser shall provide Seller with a written accounting of all payments as required by law or contract, whether actual or implied by law, to be made by or for Purchaser to or in respect of any BG Employee from and after the Closing Date in the nature of notice pay or payments in lieu of notice, statutory or contractual redundancy payments, payments for accrued but untaken holiday pay, and payment of wages or salary and benefits for a period of no longer than thirty (30) days, payment of applicable income tax for such BG Employee, and payment of National Insurance on account of such BG Employee, and a written accounting of the amount equivalent to the holiday pay for the holiday days (including National Insurance) of those fourteen (14) Employees that are not BG Employees which each such Employee has not taken, but to which such Employee is entitled, as of the Closing Date. To the extent the aggregate of all such payments plus up to $10,000 in legal fees and costs are less than the Employee Amount, Purchaser shall deliver to Seller along with such report payment of such difference in immediately available funds. Purchaser warrants that such report shall be true, correct, and complete in all respects when delivered to Seller; and Seller, at Seller’s expense, shall have the right to verify in a commercially reasonable manner that the report is true, complete, and correct upon delivery hereunder by Purchaser. Purchaser further warrants that Purchaser shall not seek credit against the Employee Amount for any amount paid to a BG Employee in excess of the amount required by law or by contract, whether actual or implied by law, to be paid to the BG Employee or, with respect to National Insurance, on the BG Employee’s behalf.

6.3. Transfer of Possession of Assets. Title to all Assets is transferring to Purchaser at Closing. Purchaser shall use its commercially reasonable endeavors to assume full possession of the Assets located at the Premises and to remove all Assets from the Premises as soon as possible after the Closing Date; provided, however, that Purchaser shall only be permitted to store such Assets, including Inventory stored at the Premises prior to the Closing Date, at the Premises for a period not to exceed ninety (90) days after the Closing (the “Transfer Period”). Further, Purchaser shall only be permitted to store Assets that are Inventory and that are

located other than at the Premises at their respective locations for sixty (60) days after the Closing Date. During the Transfer Period each of Purchaser and Seller shall use its commercially reasonable endeavors to effect the prompt transfer of possession of the Assets to Purchaser during regular business hours (unless otherwise agreed) and without undue interruption of or burden upon either party. Purchaser shall reimburse Seller for any out-of-pocket costs incurred by Seller in connection with the transfer of possession of the Assets to the Purchaser during the Transfer Period as and to the extent Purchaser has consented to such out-of-pocket costs (which consent shall not be unreasonably withheld or delayed), it being agreed that Purchaser’s denial of consent shall entitle the Seller not to perform any act that cannot be performed without the incursion of such unapproved out of pocket cost. Seller shall have no responsibility for and shall be privileged to dispose of any Asset remaining on the Premises after the last day of the Transfer Period provided that Seller delivers prior written notice to Purchaser of its intent to dispose of any Asset and affords Purchaser fifteen (15) days to remove such Asset. During the Transfer Period, Seller shall maintain property insurance and casualty insurance with regard to the Premises and shall cause Purchaser to be listed as an additional named insured (or similar status recognized in England and Wales) with regard to the Transfer Period. During the Transfer Period, Seller shall not permit or suffer to exist any Lien on, damage to, or destruction of, the Assets in Seller’s possession that, in each instance, arises through the acts or failures to act of Seller or any Seller Affiliate. In addition, during the Transfer Period, Seller shall not: (i) liquidate its remaining business or otherwise wind-up its business affairs; (ii) vacate the Premises; (iii) terminate its lease on the Premises, or (iv) discontinue utility service to the Premises, without first delivering prior written notice to the Purchaser at least fifteen (15) days prior to the commencement of any of the events listed in items (i) through (iv) of this Section 6.3.

6.4. Seller’s TUPE Obligations. Seller agrees to comply with its statutory obligations regarding information and consultation under Regulation 10 of TUPE, save to the extent that Seller is unable to do so due to a failure on the part of the Purchaser to comply with its obligations under TUPE.

6.5. ETO. Purchaser acknowledges that no later than sixty (60) days after the Closing Date, Purchaser will dismiss or give notice to dismiss the BG Employees by reason of redundancy. Purchaser reasonably believes that such dismissals will not be automatically unfair under Regulation 8(1) TUPE and will be justifiable as fair because they will be attributable to an Economic Technical or Organizational (“ETO”) reasons, entailing a change in the workforce. Purchaser will use its commercially reasonable efforts to establish the ETO reason and to ensure that any dismissals of Employees for ETO reasons are carried out using a fair procedure in accordance with applicable law.

6.6. Seller’s Liability for Failure to Establish an ETO. Purchaser agrees that in the event that any BG Employee brings any claims that he/she has been automatically unfairly dismissed under Regulation 8(1) TUPE as a result of any transaction

contemplated in connection with this Agreement, the Purchaser shall use its commercially reasonable efforts to defend such claim on the grounds that such dismissal was carried out for a fair ETO reason entailing a change in the workforce. If the Purchaser uses its commercially reasonable efforts to establish the ETO reason and to mitigate any loss with respect to any such BG Employee claim, but fails, based upon a final determination of such claim, to establish that such the dismissal was fair for an ETO reason involving a change in the workforce, then Seller and Matrix, jointly and severally, shall indemnify Purchaser from and against the established liability (the “Established Liability”) with respect to such BG Employee claim and all reasonable costs, expenses, damages, liabilities, and losses arising with respect to such Established Liability, upon written demand from Purchaser provided to Seller and Matrix. However, the total liability under this Section 6.6 of Seller and Matrix in respect of all such Established Liabilities and related losses shall not exceed US$250,000. Neither Seller nor Matrix shall have any liability under this Section 6.6 with respect to any claim that is not formally lodged with an employment tribunal or English Court prior to the date that is nine months after the Closing Date. Neither Seller nor Matrix shall have any liability under this Section 6.6 with respect to any Employee that is not a BG Employee, or for Established Liabilities and related losses and damages for a number of Employees that, in the aggregate, exceeds the number of BG Employees.

6.7. Standard for Establishing Liability for an Unfair Dismissal Claim. A liability shall only become an “Established Liability” if an Employee successfully claims, by a decision of an Employment Tribunal having jurisdiction or by an order duly issued of an English Court, that such Employee has been automatically unfairly dismissed and if the Purchaser has failed to establish that the dismissal was fair due to an ETO reason.

6.8. Automatically Unfair Dismissal. For the purpose of Sections 6.6 and 6.7 above, an “automatically unfair dismissal” means a dismissal under Regulation 8(1) of TUPE. The Purchaser’s right to cause the Escrow Agent to pay monies from the Escrow Amount to Purchaser under Section 6.6 is limited to deductions in respect of successful claims (by a decision of an Employment Tribunal or an Order of the English Court) by not more than that number of Employees that does not exceed the number of BG Employees, and does not extend to situations where the dismissal is otherwise unfair; nor, in any circumstances is the Purchaser able to deduct monies from the Escrow Amount which are attributable to any such Employee’s pay in lieu of notice or a basic award/statutory redundancy payment entitlement calculated in accordance with section 119 of the Employment Rights Act 1996, (whether awarded as part of Established Liability, or otherwise), it being acknowledged that such amounts are included in the Employee Amount. For the avoidance of doubt, the deduction referred to in Section 6.6 is limited to claims for automatically unfair dismissal only and does not extend to any other claims including sex, race, or disability discrimination.

6.9. Covenant Not to Compete. Seller and certain of the affiliates of Seller are entering into covenants not to compete for a period of one (1) year following the Closing (the “Covenants”) in the form attached hereto as Exhibit D.

6.10. Advice of Change. Seller will promptly advise Purchaser in writing, upon obtaining Knowledge, of: any event which occurred on or prior to the date of execution of this Agreement that is not disclosed herein and any event which occurs after the date of this Agreement, in each case that would, under this Agreement or any Exhibit or Schedule delivered pursuant hereto, have been required to be disclosed on the date of execution of this Agreement by Seller.

6.11. Survival. The warranties set forth in Sections 4 and 5 and the covenants contained in Article 6 of this Agreement shall survive for a period of nine months after the Closing Date. Any claim that is made before the applicable survival period expires will survive until fully and finally resolved.

6.12. Matrix Financials. Set forth on the attached Schedule 6.12 is the unaudited balance sheet of Matrix as of June 30, 2003 (the “Matrix Balance Sheet”). By executing this Agreement where indicated below, Matrix hereby warrants that, except as set forth on Schedule 6.12, the Matrix Balance Sheet presents a true and fair view of the financial condition of Matrix as of June 30, 2003, and has been prepared in accordance with United States generally accepted accounting principles, consistently applied (“US GAAP”) for Matrix, as a wholly-owned subsidiary. The Matrix Balance Sheet makes substantially full and adequate provision for all obligations, liabilities or commitments, whether fixed or contingent, and doubtful accounts receivable of Matrix to the extent such presentation would be required for the Matrix Balance Sheet to conform to US GAAP with regard to Matrix as a wholly-owned subsidiary.

6.13. Preparation of Opening Balance Sheet. By executing this Agreement where indicated below, Matrix covenants that during the thirty (30) day period commencing the Closing Date, Matrix will use its reasonable efforts to assist the Purchaser in establishing an opening balance sheet that conforms to GAAP for the Business as the same will be conducted by the Purchaser from and after the Closing Date. Notwithstanding the foregoing, Matrix shall not hereby be required to incur any out-of-pocket expenses in connection with performing the covenants set forth in this Section 6.13.

6.14. Purchase Orders. The Seller shall use commercially reasonable endeavors to transfer or cause to be transferred the Purchase Orders to Purchaser immediately upon Closing and, if requested by Purchaser, Seller shall advise each customer that submitted any Purchase Order to Seller that: (a) Purchaser shall satisfy the Purchaser Order; (b) Purchaser shall forward the invoice under the Purchase Order; and/or (c) all payments under the Purchase Order should be tendered to Purchaser. Upon the reasonable request of Purchaser, during the thirty days from and after the Closing Date, Seller shall provide reasonable assistance to Purchaser in connection with the installation of any equipment covered by a Purchase Order.

Further, to the extent Seller receives any amount in payment of a Purchase Order, Seller shall promptly notify Purchaser of such receipt and tender such amount to Purchaser. In the event that any Purchase Order is cancelled by the customer through no fault of Purchaser, then Purchaser may deduct the amount of such Purchase Order from the Escrow Amount; provided, however, that such deduction shall not constitute a payment in the nature of indemnity and, therefore, shall not be counted with respect to, or otherwise affect, the amount under the Seller Cap (as defined in Section 8.2 below). However, the total amount of the deduction from the Escrow Amount permitted hereby shall not exceed the Purchase Order Amount.

6.15. Employees During Transition. For so long as Lesley Andrews and Denise Rowllings (the “Transition Employees”) are employed by the Purchaser during the Transfer Period, Purchaser shall permit each Transition Employee to provide up to 15 hours of service in each week during the Transfer Period to the Seller for the purpose of enabling the transfer of the Business to Purchaser on behalf of the Seller and enabling the Seller to administer and wind up its affairs after the Closing Date. The provision of up to 15 hours per week of service during the Transfer Period to Seller as herein provided shall be at no cost to Seller. However, to the extent that Seller requires more than fifteen hours per week from any Transition Employee during the Transfer Period, Seller shall pay to Purchaser a fee of $100 per hour for each hour of each Transition Employee’s service time.

6.16. Return of Assets. During the sixty (60) days from and after the Closing Date, Seller shall use its reasonable efforts to secure the return of the items of Inventory that have been loaned to third parties, and Seller shall assure that each item of Inventory that is in the possession of an affiliate of Seller and not located on the Premises or at Matrix’s United States warehouses will be delivered to either the Premises or to one of Matrix’s warehouses.

6.17. Covenant to Pay Creditors. From and after the Closing Date, Seller shall use commercially reasonable efforts to pay its creditors and settle its accounts on a timely basis and to preserve (to the extent Seller then retains influence over such matters) the goodwill associated with the name “BioRobotics”.

6.18. Distribution Agreements. Purchaser and Seller acknowledge and agree that Purchaser is not hereby assuming the agreements in the nature of distribution agreements that are part of the Excluded Assets set forth on Schedule 1.16 (“Distribution Agreements”). It is Seller’s intention to terminate each of the Distribution Agreements immediately as of the Closing Date, with such termination taking effect ninety (90) days after Seller provides such notice. During the ninety (90) day period after the Closing Date, Purchaser shall supply products, including equipment and parts, relating to the Business to the distributors under the Distribution Agreements upon receipt of purchase orders therefor on substantially the same terms and conditions as applicable under the applicable Distribution Agreement.

Seller and Matrix jointly and severally agree to indemnify, defend and hold harmless Purchaser and its Affiliates, officers, directors, shareholders, managers, members, employees, independent contractors, agents, successors and assigns (collectively, the “Purchaser Parties”) from and against any and all claims, damages, liabilities, losses, costs or expenses caused by, arising out of or relating to:

(a) any inaccuracy in, or breach of any warranty of Seller contained in this Agreement, any of the Attendant Documents or any schedule to be furnished by Seller to Purchaser pursuant to this Agreement or any of the Attendant Documents;

(b) any breach or failure of Seller or to perform any covenant or agreement required to be performed by Seller pursuant to this Agreement or any of the Attendant Documents;

(c) any Excluded Liability;

(d) any actual defect in any product manufactured by Seller prior to the Closing;

(e) Each and every cost, claim, liability, expense or demand which relates to or arises out of or in connection with any Employee prior to the Closing Date, or any Employee claim under Regulation 11 of TUPE due to Seller’s failure to comply with Seller’s obligation under Regulation 10 of TUPE, except to the extent such cost, claim, liability, expense or demand relates to the failure of the Purchaser to comply with the Purchaser’s obligations under Regulation 10 of TUPE or any claim by any person not listed on Schedule 4.10 claiming to be an employee of the Purchaser after the Closing Date, which claim is alleged by reason of TUPE and the application of TUPE to the transactions contemplated by this Agreement; and

(f) any and all actions, suits, proceedings, demands, assessments, judgments, costs and expenses, including reasonable attorneys’ and consultants’ fees (collectively, “Related Expenses”), incident to any of the foregoing.

provided, however, that no later than thirty (30) days after learning of the assertion of any claim, demand, suit, action or legal, administrative or other proceeding by any person (other than a Party) or any other governmental body (a “Third Party Claim”) against any of the Purchaser Parties for which any Purchaser Party intends to claim indemnification under this Section 8.1 (each, a “Third Party Claim”), such Purchaser Party shall notify the Seller, Matrix and the parties set forth in Section 9.3 and afford Seller and Matrix the opportunity to join in the

defense or settlement thereof at Seller’s or Matrix’s own expense with counsel of their choosing, and such Purchaser Party shall cooperate fully to make available to the Seller and Matrix all pertinent information under its control or in its possession. Purchaser shall have the right (but not the obligation) to afford to Seller and Matrix the opportunity to assume the defense or settlement of such Third Party Claims at their own expense with counsel of their choosing, provided that Seller and Matrix shall not settle any such claim without the prior written consent of such Purchaser Party, which consent shall not be unreasonably withheld or conditioned. If any Purchaser Party undertakes the defense (including by failing to afford Seller or Matrix the right to undertake the defense) of any Third Party Claim for which any Purchaser Party may or will seek indemnification hereunder from Seller or Matrix, the Purchaser Party shall use commercially reasonable efforts exercised in good faith to defend against such Third Party Claim and to mitigate any damages suffered by any Purchaser Party with respect to such Third Party Claim.

8.2. Limitation on Seller/Matrix Indemnification. Notwithstanding anything to the contrary contained in this Agreement, (i) the rights of Purchaser to indemnification under this Article 8 and under Section 6.6 shall constitute the sole and exclusive remedy of the Purchaser Parties from and after the Closing for any breach by the Seller or Matrix of any provision of this Agreement, and (ii) no claim, including with respect to a Third Party Claim, may be asserted nor any action commenced against either of Seller or Matrix for indemnification under Section 6.6 or Section 8.1 unless written notice describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or action is received by the Seller within nine months after the Closing Date. Any provision of this Agreement to the contrary notwithstanding, the indemnification obligations of the Seller and Matrix pursuant to Sections 6.6 and 8.1 shall not exceed, in the aggregate, one million, three hundred and fifty thousand United States Dollars (US$1,350,000) (the “Seller Cap”); provided, however, that the Seller Cap shall not apply to indemnifications claims made pursuant to either (a) Section 6.14, or (b) Section 8.1(a) relating solely to an inaccuracy in, or a breach of, the warranty of Seller set forth in Section 4.10 concerning Employee Bonuses (such specified claims (“Exempt Claims”), which Exempt Claims may be made by any Purchaser Party without limitation as to amount and without reducing the amount available under the Seller Cap. Any amounts payable by Seller or Matrix pursuant to Sections 6.6 or 8.1 shall first be deducted from the Escrow Amount pursuant to the Escrow Agreement, and, only once the Escrow Amount is zero, shall the same be payable by Seller or Matrix, as the case may be. Nothing in this Agreement, including, but not limited to the Seller Cap and the nine-month period in which to bring claims, shall limit the liability of either Matrix or Seller in respect of a proven allegation of fraud, fraudulent misrepresentation or willful misstatement. Further nothing herein shall limit the right of any Purchaser Party to pursue equitable relief against the Seller or Matrix to enforce Purchaser’s rights under this Agreement, so long as the relief sought is not monetary in nature or reasonably capable of being reduced to monetary damages.

8.3. Indemnification of Seller. Purchaser hereby agrees to indemnify, defend and hold harmless Seller and its officers, directors, shareholders, managers, members, employees, independent contractors, agents, successors and assigns (collectively, the “Seller Parties”) from and against any and all claims, damages, liabilities, losses, costs or expenses caused by, arising out of or relating to:

(a) any inaccuracy or misrepresentation in, or breach of any representation or warranty of Purchaser contained in this Agreement, any of the Attendant Documents or any schedule to be furnished by Purchaser to Seller pursuant to this Agreement or any of the Attendant Documents

(b) any breach or failure of Purchaser to perform any covenant or agreement required to be performed by it pursuant to this Agreement or any of the Attendant Documents;

(c) employment by the Purchaser of the Employees or the termination of that employment after the Closing Date (subject always to the deduction from the Purchase Price of the Employee Amount and right of Purchaser as against Seller and/or Matrix with respect to Employee claims under Section 6.6, or Section 8.1 to the Escrow Amount or under this Article 8); and

(d) any and all Related Expenses incident to any of the foregoing.

8.4. Indemnification Obligations of Purchaser Limited. The liability of the Purchaser under Section 8 shall not exceed One Million, Two Hundred and Fifty Thousand United States Dollars (US$1,250,000) (the “Purchaser Cap”); provided, however, that the Purchaser Cap shall not apply to claims based on fraud, willful misconduct or intentional misrepresentations of material fact. Further, Purchaser shall not be liable to indemnify any Seller Party for any claim unless notice of such claim is provided to Purchaser within nine months after the Closing Date or, solely with respect to a claim asserted under Section 6.2, thirty (30) days after the provision by Purchaser of the report to be provided pursuant to Section 6.2 hereof, if later.

8.5. Settlement. Notwithstanding anything contained in this Agreement to the contrary, Purchaser will have the right to settle any claims or actions, the defense of which Seller or Matrix would otherwise be entitled to assume pursuant to the provisions of this Section 8, after first giving Seller and Matrix not less than five (5) days prior written notice of such proposed settlement (the “Settlement Notice”), if it is necessary to settle such actions or claims in order to prevent a material adverse affect on the Business and the proposed settlement is commercially reasonable in light of the circumstances.
