All remaining employees of Sigma and its Affiliates shall continue to be subject to the protections of the Confidentiality Agreement signed by the Parties as of December 24, 2001, and except as provided herein, IVD shall not directly or indirectly hire or solicit to hire any such employees of Sigma or its Affiliates other than the Employees or induce or encourage any such other employee to terminate his or her association with Sigma. Should IVD hire any employee of Sigma, without Sigma's prior written consent, which will not be unreasonably withheld, other than the Employees, within 36 months following the Closing, IVD shall reimburse Sigma for the amount of any severance payments made by Sigma in respect of the termination of such employee's employment in connection with the sale of the Assets to IVD. Sigma shall not have any responsibility for ensuring IVD's ability to hire any employees to whom IVD has made offers nor for the terms of any of the Employment Agreements with such persons. (b) IVD will have sole responsibility for any obligations or liabilities to the Employees accepting offers of Employment Agreements that arise from all wages, benefits and other compensation, all severance obligations and all required ancillary payments of taxes, insurance and related social requirements, to the extent for services rendered on or after the Closing Date. Such liabilities of IVD are part of the "Assumed Liabilities" defined in Section 1.2 of this Agreement. (c) Sigma shall retain all liabilities for wages, benefits and other compensation and/or required ancillary payments of Taxes, insurance and related social requirements (including all severance and other employment related payments related to the EIA Product Line through the day of Closing), (i) in respect to the services rendered prior to the Closing Date by the Employees accepting the Employment Agreements, and (ii) with respect to services rendered at any time by all employees other than those accepting the Employment Agreements. Such liabilities of Sigma are part of the "Retained Liabilities" defined in Section 1.2 of this Agreement. 4.5 NONCOMPETITION AND CONFIDENTIALITY In consideration of the consummation of the transactions contemplated hereby: (a) Sigma shall not, for a period of three (3) consecutive years from the Closing Date, (i) directly or indirectly, anywhere in the world, through any Affiliate or other 11 entity, as a principal, partner, agent or otherwise, compete, assist in or provide financial resources to any activity which directly manufactures or sells any products contained in the EIA Product Line or products or services in the in-vitro diagnostic enzyme immunoassay business regulated by the FDA; or (ii) directly or indirectly solicit, encourage to leave employment, or hire any of the former employees hired by IVD pursuant to the Employment Agreements; provided, however, that such restrictions shall not apply to any such employee who responds to a general solicitation for employment with Sigma, including any employee responding to an advertisement for employment in a newspaper, trade journal or web site, regardless of whether such solicitation is made by Sigma or through a third party; or (iii) solely with respect to activities concerned with sales of the EIA Product Line, directly or indirectly sell, solicit for sale, or call on for purposes of selling, any customer contained on the Customer Lists (it being expressly acknowledged by IVD that Sigma may call upon such customers for all other purposes). (b) Sigma shall not, for a period of two (2) consecutive years from the Closing Date, use or disclose to anyone except authorized personnel of IVD, whether or not for its benefit or otherwise, any confidential matters which both solely concern the EIA Product Line and are of a nature that Sigma has maintained as confidential during its ownership of the EIA Product Line, as described in Schedule 4.5(b) (the "Confidential Information"); provided that "Confidential Information" shall not include any information that is used, or is expected to be used, in Sigma's or its Affiliates' other areas of business other than the EIA Product Line. The preceding obligations to maintain such Confidential Information in confidence shall not apply to the extent that (i) the information is or becomes in the future public knowledge through no fault or omission of Sigma, or (ii) the information is required to be disclosed by law. (c) Sigma acknowledges that the foregoing restrictions in subsections (a) and (b) above are reasonable and agrees that in the event of any breach thereof the harm to IVD will be irreparable and without adequate remedy at law, and therefore that injunctive relief with respect thereto will be appropriate. To the extent that any provision of this Section 4.5 is adjudicated to be invalid or unenforceable because it is overbroad, that provision shall not be void but rather shall be limited only to the extent required by applicable law and enforced as so limited. 4.6 TERMINATION OF DISTRIBUTORSHIP AGREEMENT As of the Closing, the Distributorship Agreement by and between IVD and Sigma effective as of May 1, 1999, the Distributorship Agreement between IVD and Sigma effective as of October 1, 2000, and all related rights and obligations under each of the foregoing agreements shall terminate. 4.7 SUPPLY OF REAGENT UNDER WARRANTY TO CUSTOMERS Notwithstanding the provisions of Section 1.2 above, IVD shall supply to all previous customers of Sigma, with respect to sales of reagents prior to the Closing, any replacement reagent which any such customer has demanded and which the original supplier of reagent to Sigma has an obligation or is otherwise willing to supply. IVD shall use its best efforts to satisfy any such customer complaints with respect to sales prior to Closing by seeking to arrange for the supply of 12 replacement reagents at such supplier's cost. In the event that no such reagent is provided by the supplier at its cost, despite IVD's best efforts, then IVD shall sell such replacement reagent to Sigma at IVD's cost. Notwithstanding the foregoing covenant, IVD assumes no direct liability to such customers for sales of reagents by Sigma prior to Closing. 4.8 LIMITED USE OF SIGMA TRADEMARK. Sigma has agreed to permit IVD limited rights to use the "Sigma" brand name in connection with the resale of the EIA Product Line Inventory which IVD acquires hereunder, for a period not to exceed: the earlier of (a) two years or (b) the remaining shelf life of the Inventory (which shall be included in the indemnification by IVD of Sigma pursuant to Section 5.1). Promptly upon the expiration of the applicable license period, IVD shall cease all sale or other transfer of Inventory, Records and any other Assets on which the "Sigma" brand name may appear, and no later than 30 days thereafter IVD shall complete removal of any and all use and indication of the "Sigma" name from the Inventory, the Records and any other Assets remaining in its possession. With respect to instruments contained in the Inventory that are already installed at customer locations, IVD shall remove or "sticker-over" the "Sigma" brand name from such products within 8 months from the Closing. ARTICLE V INDEMNIFICATION 5.1 INDEMNIFICATION BY IVD From and after the Closing Date, IVD shall defend, indemnify and hold harmless Sigma and its Affiliates and shareholders and each of their employees, officers, directors and agents from and against any and all claims, losses, arbitration and court costs, reasonable attorneys' fees, demands, causes of action, suits, judgments, debts, liabilities and expenses, including arbitration costs and reasonable attorneys' fees incurred in establishing the right to indemnification (collectively referred to for purposes of this Article V as a "Claim") in any tribunal, domestic or foreign, resulting from (a) any failure of IVD promptly to carry out, perform, satisfy and discharge any of its covenants, agreements, undertakings, liabilities or obligations under any of the Transaction Documents, (b) any breach of any representation or warranty by IVD contained herein, (c) IVD's ownership or use of the Assets after the Closing, or (d) any obligation or liability arising from the Assumed Liabilities. 5.2 INDEMNIFICATION BY SIGMA (a) From and after the Closing Date, Sigma shall defend, indemnify and hold harmless IVD and its Affiliates and shareholders and each of their employees, officers, directors and agents from and against any and all Claims resulting from or arising out of (i) any failure of Sigma promptly to carry out, perform, satisfy and discharge any of its covenants, agreements, undertakings, obligations or liabilities under any of the Transaction Documents, or (ii) any breach of any representation or warranty of Sigma contained herein, (iii) the failure of Sigma to assume responsibility for any Retained Liability, (iv) any failure to comply with any "bulk sales," "bulk 13 transfer" or similar laws other than to the extent such Claims are Assumed Liabilities; or (v) as provided in Section 5.2(b) hereof. (b) Sigma shall indemnify IVD in the manner and by the amount listed below, for each Customer Leased Instrument and each Third-Party Leased Instrument returned by existing Sigma customers, in both instances only if such return is fully consummated during the 12 months immediately following Closing and the criteria set forth in (A) or (B) have been met: (A) The amount of such Claim for indemnification shall be equal to $10,000 if and only if each of the following conditions have been met: (1) IVD has lost the customer due to factors caused by Sigma's handling of the account pre-Closing; (2) IVD has used its best efforts since Closing to retain the customer, including without limitation the provision of appropriate levels of field services and technical support for all in-place instruments; and (3) the returned instrument has not been nor is reasonably expected to be replaced by another instrument from IVD; or (B) The amount of such Claim for indemnification shall be equal to $5,000 if and only if each of the following conditions has been met: (1) IVD has not lost the customer due to factors caused by Sigma's handling of the account pre-closing; (2) IVD has used its best efforts since Closing to retain the customer, including without limitation the provision of appropriate levels of field services and technical support for all in-place instruments; and (3) the returned instrument has not been nor is reasonably expected to be replaced by another instrument from IVD. Any Claims under this Section 5.2(b) are subject to being offset by a $10,000 credit in Sigma's favor for each new Customer Leased Instrument or new Third-Party Leased Instrument delivered to a customer by Sigma in the time period from March 1, 2002 through Closing. The foregoing shall be IVD's sole recourse against Sigma for any and all Claims relating to the return of any Customer Leased Instruments. Each new Customer Leased Instrument or new Third-Party Leased Instrument delivered to a customer by Sigma in the time period from March 1, 2002 through Closing is identified as such on Schedule 1.1(b). (c) Notwithstanding the foregoing, Sigma shall not be required to indemnify any party under subsections (i), (ii) or (v) of Section 5.2(a) or Section 5.2(b), unless and until the aggregate amount of all Claims exceeds Six Hundred Fifty Thousand Dollars ($650,000) (the "Deductible"), and then only to the extent of amounts in excess of the Deductible. Further, in no event shall Sigma's aggregate indemnification obligation under subsections (i), (ii) or (v) of Section 5.2(a) and Section 5.2(b) exceed Three Hundred Fifty Thousand Dollars ($350,000). 5.3 INDEMNIFICATION PROCEDURES Promptly after acquiring knowledge of any Claim against which a Party entitled to indemnification hereunder (the "Indemnified Party") may seek indemnification against the other Party (the "Indemnifying Party") pursuant to this Article V, the Indemnified Party shall give written notice thereof to the Indemnifying Party; provided, however, that failure to provide such notice will 14 not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party under this Agreement unless (a) the Indemnified Party fails to give written notice to the Indemnifying Party within forty (40) days of the date the Indemnified Party acquires knowledge of such Claim or (b) the Indemnifying Party is prejudiced as a result of such failure. To the extent that the Claim consists of a claim, suit or action by a third party (an "Action"), the Indemnifying Party shall be entitled to participate in the defense of such Action and, to the extent that it so elects by written notice to the Indemnified Party promptly after receiving the aforesaid notice from such Indemnified Party, to assume control of such defense; provided however, that (y) the Indemnified Party shall at its own expense be entitled to participate in the defense of such Action and to employ separate counsel and (z) the Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to each Indemnified Party of a release from all liability in respect of such Action. After written notice by the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of any such Action, the Indemnifying Party shall not be liable to such Indemnified Party hereunder for any legal expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. 5.4 COMPUTATION OF CLAIMS All computations of Claims and the amount of indemnification to which any Indemnified Party is entitled under this Article V shall be made after deduction of all proceeds of insurance (net of retroactive premiums and self-insurance retention) recoverable by the Indemnified Party with respect to such Claims. 5.5 EXCLUSIVE REMEDY The Parties agree that the provisions of this Article V set forth the exclusive remedy of the Indemnified Parties after the Closing with respect to any Claims under any of the Transaction Documents. 5.6 SETOFF IVD shall not be entitled to set off any amounts owing by Sigma to IVD or any party entitled to indemnification pursuant to Section 5.2, as an Indemnified Party or otherwise, against any amounts owed to Sigma pursuant to the Transition Services Agreement, except to the extent that such amounts owing by Sigma are owing pursuant to a binding judgment or arbitration award. 5.7 EXPIRATION OF REPRESENTATIONS AND WARRANTIES All of the representations and warranties contained in Articles II and III hereof are made only as of the Closing Date and shall survive Closing only for purposes of indemnification under this Article V for a period of twelve (12) months from the Closing Date. All other obligations under this Agreement shall expire according to their terms. 15 5.8 KNOWLEDGE OF BREACH If, as of Closing, IVD has actual knowledge of any fact, circumstance or situation which constitutes a breach, or if known to Sigma would constitute such a breach, or will with the passage of time or the giving of notice constitute a breach, of any representation, warranty or covenant of Sigma hereunder or a failure of any conditions to IVD's obligations under this Agreement or the Schedules and Exhibits hereto, and IVD has not given Sigma prompt notice thereof prior to Closing, IVD shall be precluded from seeking indemnification with respect to such breach under this Article V. ARTICLE VI MISCELLANEOUS PROVISIONS 6.1 Arbitration Except as otherwise provided in Section 4.5(c) or in this Section 6.1, in the event of any controversy or claim arising under or in relation to this Agreement, including any issue about payment of amounts due, the Parties shall, in good faith, attempt to resolve the controversy or claim by negotiation. If the controversy or claim cannot be resolved within sixty (60) days, then it shall be settled exclusively by binding arbitration in accordance with the Arbitration Rules of the American Arbitration Association ("AAA") and shall be held in Atlanta, Georgia. There shall be three (3) arbitrators: one selected by the Party who requests arbitration, who shall notify the other Party of the individual selected at the time that notice of arbitration is sent; one selected by the other Party within ten (10) days of receipt of notice of arbitration; and one selected by the Parties jointly within ten (10) calendar days thereafter or, failing their agreement, selected pursuant to the rules of the AAA. No arbitrator shall be related to, employed by, or have at any time a substantial ongoing business relationship with any Party hereto or any of their respective Affiliates. The losing Party in the arbitration shall reimburse the prevailing Party for all costs and expenses, including reasonable attorney fees, incurred in connection with the arbitration. The decision of the arbitrators shall be final and binding on the Parties and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction. The provisions of this arbitration clause shall not be applied to the determination of questions affecting validity or scope of any patents, trademarks or other intellectual property rights. 16 6.2 ALLOCATION OF TAXES AND CERTAIN FEES AND EXPENSES (a) For any personal property, ad valorem and any other similar local or state taxes relating solely to the Assets or the EIA Product Line for any taxable year or period commencing prior to the Closing and ending on or after the Closing Date (a "Straddle Period "), Sigma shall pay to IVD within fifteen (15) days after the date on which Taxes are paid with respect to such periods an amount that relates to the portion of such taxable period ending immediately prior to the Closing Date to the extent such Taxes are not paid by Sigma prior to Closing. For purposes of this Section, the portion of such Tax that is allocated to Sigma shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction, the numerator of which is the number of days in the taxable period ending immediately prior to the Closing Date, and the denominator of which is the number of days in the entire taxable period. Any credits relating to a taxable period that begins before and ends on or after the Closing Date shall be allocated in a similar manner, with the entire credit multiplied by a fraction, the numerator of which is the number of days prior to the Closing Date and the denominator of which is the number of days in the entire taxable period. All determinations necessary to give effect to the allocations described in this Section shall be made in a manner consistent with the prior practice of Sigma, except for changes required by changes in law or fact. (b) IVD shall assume and pay all liabilities for sales, use, transfer, value-added and other Taxes arising from the transfer of the Assets and the Assumed Liabilities to IVD and all fees and expenses related to the recordation of assignments against the intellectual property rights set forth in the Trademark Assignment. Except as otherwise provided herein, each of the Parties shall pay all costs and expenses incurred on its behalf in connection with the negotiation, preparation and execution of the Transaction Documents and the consummation of the transactions contemplated thereby. 6.3 NOTICE (a) Any notice required or permitted to be given hereunder shall be in writing and shall be (i) personally delivered, (ii) transmitted by postage pre-paid first class certified United States mail, (iii) transmitted by pre-paid, overnight delivery, or (iv) transmitted by facsimile transmission (with the confirmation by certified mail as described below) and shall bear the address or facsimile number shown in this Section 6.3 or such other address or facsimile number as may be designated in writing hereafter by such Party: If to IVD: If to Sigma: IVAX Diagnostics, Inc.
