COMBINATION --------------------------------- THIS AGREEMENT AND PLAN OF COMBINATION (this "Agreement"), is made and --------- entered into as of June 24, 1997, by and between Diagnostic Holdings, Inc., a Delaware corporation ("Dade"), and Hoechst AG, a German corporation ("Hoechst"). ---- ------- Each of Hoechst and Dade possess substantial expertise, know-how, skilled personnel, facilities and organization relating to the business of developing, manufacturing and marketing in vitro diagnostic equipment, reagents, consumable supplies and services worldwide. Hoechst and certain of its subsidiaries currently operate the worldwide business of the research, development, manufacture, marketing, sale, distribution and service of human in vitro diagnostic equipment, reagents, consumable supplies and services (the "Business"). -------- As of the Closing, substantially all of the assets, properties, rights and obligations of the Business will be owned, directly or indirectly, by Behring Diagnostics GmbH (the "GMBH Company"), Hoechst Diagnostics Holding ------------ Corporation ("HDHC") and certain affiliates of Hoechst identified on the ---- Acquired Entities Capitalization Schedule to be acquired directly by Dade - ----------------------------------------- hereunder (collectively, the "Acquired Companies"). The issued and outstanding ------------------ stock of the Acquired Companies (other than the stock identified on the Acquired -------- Entities Capitalization Schedule as "Excluded Stock") is hereinafter - -------------------------------- -------------- collectively referred to as the "Stock." ----- Subject to the terms and conditions set forth herein, Dade and Hoechst desire to effect a combination of the Business with the business of Dade and its subsidiaries by Hoechst transferring the Stock to Dade in exchange for an equity interest in Dade. Following consummation of the combination, Dade shall change its name to "Dade Behring Holdings, Inc." and shall cause its wholly owned --------------------------- subsidiary, Dade International Inc., to change its name to "Dade Behring, Inc." ------------------ NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby agree as follows: ARTICLE I TRANSFER OF BUSINESS -------------------- 1.1 Transfer of Stock to Dade. On the terms and subject to the ------------------------- conditions set forth in this Agreement, Dade shall acquire from Hoechst, and Hoechst shall sell, transfer and deliver (or cause to be sold, transferred and delivered) to Dade on the Closing Date, the Stock, free and clear of all liens, mortgages, charges, security interests, encumbrances, and other restrictions of whatever nature ("Liens"). ----- 1.2 Consideration for Transfer of Stock to Dade. In consideration for ------------------------------------------- the Stock (the "Purchase Price"), Dade shall: (a) sell, transfer and deliver, -------------- free and clear of all Liens, to Hoechst 5,198,323 shares of Common Stock of Dade, par value $.01 per share ("Common Stock"), and 519,451 shares of Class L ------------ Common Stock, Series B, of Dade, par value $.01 per share ("Class L Common, --------------- Series B"), (b) issue to Hoechst a warrant (the "Warrant") in form and in - -------- ------- substance as set forth in Exhibit A attached hereto, initially exercisable into --------- 1,279,587 shares of Common Stock and 127,865 shares of Class L Common, Series B, and (c) transfer and deliver to Hoechst $100,000 in immediately available funds. 1.3 Closing Transactions. The closing of the transactions contemplated by -------------------- this Agreement and the other Combination Documents (the "Closing") shall take ------- place in New York, New York, at 6:00 p.m. New York time on July 31, 1997 or, if the conditions to the Closing as set forth in Article II have not been satisfied on or prior to such date, within 10 days following satisfaction of such conditions on a date mutually selected by Dade and Hoechst. The date and time of the Closing are referred to herein as the "Closing Date"; provided that, for ------------ -------- all purposes of this Agreement, the Closing shall be deemed to be effective as of the opening of business on the Closing Date; provided further that the -------- ------- ---- transfer of title of the issued and outstanding capital stock of the GMBH Company shall occur in Basel, Switzerland in the presence of an authorized Swiss notary immediately after the Closing pursuant to a deed in form and substance as set forth in Exhibit B. --------- 1.4 Certain Post-Execution Agreements. --------------------------------- (a) Hoechst and Dade shall in good faith discuss and shall use reasonable best efforts to reach an agreement on (i) a valuation of the Purchase Price and (ii) an allocation of such value among the Acquired Entities. If on or before the date that is 20 Business Days following the date on which representatives of Dade first meet with the Chief Financial Officer of Hoechst to discuss a valuation, the parties cannot agree on a valuation of the Purchase Price or allocation of such valuation, Hoechst shall deliver its valuation and allocation to Dade (the "Hoechst Valuation"). Within Five Business Days after ----------------- receipt of such valuation and allocation from Hoechst (the "Valuation Drop -------------- Date"), Dade shall either accept such valuation and allocation or terminate this agreement pursuant to Section 6.1(d) hereof. If Dade does not terminate this Agreement pursuant to Section 6.1(d) hereof by the Valuation Drop Date, the Hoechst Valuation shall be deemed to be the valuation of the Purchase Price and the related allocation of the Purchase Price for purposes of this Agreement. Dade and Hoechst agree upon determination of the allocation of the Purchase Price to adhere (and to cause their respective affiliates to adhere) to such allocations for tax reporting and accounting purposes. All allocations made pursuant to this Section 1.4 shall be binding upon the parties, their affiliates and each of their respective successors and assigns, and the parties and their affiliates shall report the transactions contemplated by the restructuring documents listed on the attached Exhibit C (the "Restructuring Documents") and --------- ----------------------- the Combination Documents in accordance with such allocations. -2- (b) Hoechst and Dade shall in good faith negotiate a limit (the "Consent Indemnity Limit") to the amount of the Loss in respect of the - ------------------------ Indemnified Liability specified in Section 9.25(a)(vi) for which Hoechst shall indemnify Dade. If on or before the Termination Date Hoechst and Dade cannot agree upon the Consent Indemnity Limit, either Dade or Hoechst may terminate this Agreement pursuant to Section 6.1(h) hereof. (c) Hoechst and Dade shall in good faith negotiate additional agreements with respect to the level of capital expenditures for the Business since December 31, 1996 (the "Expenditure Agreement"). If by the Valuation Drop --------------------- Date Hoechst and Dade cannot agree upon the Expenditure Agreement, Dade may terminate this Agreement pursuant to Section 6.1(i) hereof on the Valuation Drop Date. (d) Hoechst and Dade shall in good faith negotiate an agreement as to which additional stockholders' rights under the Stockholders Agreement shall be "Designation Rights" for purposes of Section 7.6(a). If Hoechst and Dade cannot reach agreement, Dade may terminate this Agreement after the Valuation Drop Date pursuant to Section 6.1(j) hereof. 1.5 Net Asset Adjustment. Hoechst agrees that if Net Assets are less -------------------- than $229.7 million on the Closing Date, then Hoechst shall pay Dade, within five Business Days after the determination of Net Assets (as set forth in Section 1.6 below), the difference between such amounts. Dade agrees that if Net Assets are greater than $229.7 million on the Closing Date, then Dade shall pay Hoechst, within five Business Days after the determination of Net Assets (as set forth in Section 1.6 below), the difference between such amounts. Any payment made under this Section 1.5 shall be made, together with interest thereon from the Closing Date to the date of payment at the prime rate announced by Bankers Trust Company from time to time (the "Prime Rate"), in immediately ---------- available funds by wire transfer. Exhibit D attached hereto contains certain --------- balance sheet categories set forth on the Latest Balance Sheet (as defined in Section 4.6(a) hereto). As used herein, "Net Assets" means the excess of the ---------- assets of the Business appropriately included within the asset categories set forth under the "To JV" heading (and above the line entitled "Working Capital (for Net Asset Test)") on Exhibit D, less the liabilities of the Business --------- appropriately included within the liability categories set forth under such "To JV" heading (and above the line entitled "Working Capital (for Net Asset Test)") on Exhibit D (other than "Restructuring Costs" and "Income Taxes Payable"), less --------- any long-term liabilities of the Business, determined in each case as of the opening of business on the Closing Date, in United States Dollars at the conversion rates used to prepare the Latest Balance Sheet, on a consolidated basis in accordance with U.S. GAAP and on a basis consistent with the Latest Balance Sheet. Without limiting the generality of the foregoing, Hoechst and Dade agree that the audit procedures, scope of audit and materiality thresholds (with respect to both individual items and cumulative reporting) utilized in the preparation of the Latest Balance Sheet (and as disclosed to Dade's accountants) will be utilized in the determination of Net Assets. In calculating Net Assets, (A) the amount of any liability or other obligation (whether accrued, absolute or contingent, whether known or unknown or whether due or to become due) for which Hoechst is obligated to pay under this Agreement (or under any agreement contemplated by -3- Section 7.2(g)) shall be excluded from the calculation of Net Assets, (B) it shall be assumed that the options set forth in Sections 7.18(a) and 7.18(b) have been exercised (i.e., the pro forma effect of transfers under such options shall have been taken into account by including the historical recorded accounts in determining Net Assets) and the purchase prices therefor have been paid (i.e., Net Assets shall be reduced by the amount of such purchase price), (C) the purchase price for the transaction set forth in Section 7.20 shall be deducted from Net Assets (unless the amount of such purchase price shall have been previously paid by Hoechst to Dade in cash) and the related Thai assets and liabilities shall be excluded from Net Assets (except that any such liabilities (of the kind used in calculating Net Assets) in excess of current assets (of the kind used in calculating Net Assets) shall reduce Net Assets), and (D) with respect to 1997 target bonuses (aggregating approximately $6.1 million for fiscal 1997), the liability reflected in the determination of Net Assets shall be (x) 75% of such amount if the Closing occurs prior to October 1, 1997, or (y) a pro rata portion of such amount (based on days elapsed during 1997 on or prior to the Closing) if the Closing occurs on or after October 1, 1997; provided that, if the Closing occurs after December 31, 1997, the -------- liabilities reflected in the determination of Net Assets shall equal the aggregate 1997 target bonuses, plus a pro rata portion of such amount for the portion of 1998 on or prior to the Closing, less any payment of 1997 target bonuses made in 1998 but prior to the Closing. Notwithstanding the foregoing, the "$229.7 million" amount set forth in this Section shall be increased by the amount (if any, but in no event by more than $11.48 million in the aggregate) of any liability or liabilities included in the determination of such $229.7 million target and which would be an Indemnified Liability (or for which Hoechst would otherwise be obligated to pay hereunder (or under any agreement contemplated by Section 7.2(g)), including pursuant to Sections 7.12 and 7.13 hereunder) if such liability or liabilities existed on the Closing Date; provided that, in no event, shall the $229.7 million target exceed $241.18 - -------- million. 1.6 Post-Closing Determination. Within 90 days after the Closing Date, -------------------------- Hoechst and its auditors will prepare and deliver to Dade an audited calculation of Net Assets determined in accordance with Section 1.5 and from the audited consolidated balance sheet of the Business as of the Closing Date (the "Draft ----- Balance Sheet"). Dade and its auditors shall, during the preparation of the - ------------- Draft Balance Sheet by Hoechst and during the period for which an objection may be filed pursuant to the next sentence, have reasonable access to Hoechst, and Hoechst and its auditors shall make available to Dade and its auditors all records and work papers used in preparing the Draft Balance Sheet. If Dade disagrees with the computation of Net Assets reflected on the Draft Balance Sheet, Dade may, within 60 days after receipt of the Draft Balance Sheet, deliver a written notice (an "Objection Notice") to Hoechst setting forth Dade's ---------------- calculation of Net Assets; provided that the running of such period will be -------- suspended during any period that Hoechst or any of its subsidiaries fail to comply with its obligations set forth in the immediately preceding sentence. If an Objection Notice is not delivered within such time period, then the amount of Net Assets set forth in the Draft Balance Sheet shall be conclusive and binding upon Dade and Hoechst and their respective affiliates. Dade and Hoechst will use reasonable efforts to resolve any disagreements as to the computation of Net Assets, but if they do not obtain a final resolution within 30 days after Hoechst has received the Objection Notice, Dade and Hoechst will jointly retain an independent accounting firm (the -4- "Firm") to resolve any remaining disagreements. If Dade and Hoechst are ---- unable to agree on the choice of the Firm, the Firm shall be Deloitte & Touche LLP. Dade and Hoechst shall direct the Firm to render a determination within 30 days of its retention and Dade, Hoechst and their respective employees shall cooperate with the Firm during its engagement. The Firm shall consider only those items and amounts in the Draft Balance Sheet set forth in the Objection Notice that Dade and Hoechst are unable to resolve. The Firm's determination shall be based on the definition of Net Assets included herein. The determination of the Firm will be conclusive and binding upon Dade and Hoechst and their respective affiliates. The fees and expenses ("Firm Fees") of the --------- Firm shall be paid by Dade, subject to the reimbursement by Hoechst as set forth in the next sentence. If any of the items set forth in the Objection Notice and submitted to the Firm for determination are resolved in favor of Dade, Hoechst shall promptly reimburse Dade by wire transfer of immediately available funds in an amount equal to (the "Reimbursement Calculation") (if and only if a positive -------------------------- number) the Firm Fees multiplied by a factor equal to A minus B plus twice ----- ---- A multiplied by B; where "A" is the quotient obtained by dividing the amount ---------- of the items in the Objection Notice resolved by the Firm in favor of Dade by the total amount of such items, and "B" is the Hoechst Percentage. If the Reimbursement Calculation yields a negative number, Dade shall promptly pay Hoechst by wire transfer of immediately available funds in the absolute amount of such Reimbursement Calculation. 1.7 Certain Related Party Receivables. Immediately after the Closing --------------------------------- (and after taking into account the actions contemplated by Section 3.2(h) hereof), Dade and Hoechst acknowledge and agree that the Acquired Companies will own an aggregate of $26.9 million face amount of "accounts receivable from owner" and "accounts receivable from related parties" (as such terms are used in the Latest Balance Sheet referred to in Section 4.6 hereof). Within 30 days after the Closing, Hoechst shall pay (or cause to be paid) to HDHC or the U.S. Company the face amount of such receivable in immediately available funds by wire transfer. In no event shall such accounts receivable be taken into account in the calculations of Net Assets hereunder. ARTICLE II CONDITIONS TO CLOSING --------------------- 2.1 Conditions to Dade's Obligations.

ARTICLE VI TERMINATION ----------- 6.1 Termination. This Agreement may be terminated at any time prior to ----------- the Closing: (a) by the mutual written consent of Dade and Hoechst; (b) by Dade, if there has been a material breach by Hoechst of a representation or warranty or a covenant or agreement set forth in this Agreement, which has not been cured within 30 days after written notification thereof by Dade and would cause a condition to Closing to be unable to be satisfied by the dates set forth in Section 6.1(e) below; (c) by Hoechst, if there has been a material breach by Dade of a representation or warranty or a covenant or agreement set forth in this Agreement, which has not been cured within 30 days after written notification thereof by Hoechst and would cause a condition to Closing to be unable to be satisfied by the date set forth in Section 6.1(e) below; (d) by Dade, if Dade does not accept the Hoechst Valuation by the Valuation Drop Date pursuant to Section 1.4 hereunder; -46- (e) by either Dade or Hoechst, if the Closing has not occurred by December 31, 1997 (the "Termination Date"); provided that the party seeking ---------------- -------- termination pursuant to this clause (e) of Section 6.1 is not in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement; provided further that, if Consents required under Sections -------- ------- 2.1(c) and 2.2(c) with respect to H-S-R and EC Merger Control have not been obtained by the Termination Date, the Termination Date shall be automatically extended to March 31, 1998 so long as neither Dade nor Hoechst determines in its reasonable judgment that either (i) such H-S-R and EC Merger Control Consents cannot be obtained on or prior to March 31, 1998 or (ii) the continuation of this Agreement would have a Material Adverse Effect on either the Business, taken as a whole, or the Dade Business, taken as a whole; (f) by Dade within five Business Days after receipt by Dade of the schedule described in Section 3.2(j) hereunder, if (i) Dade determines that it is not reasonably satisfied with (A) the financial information that Hoechst has indicated pursuant to such schedule that it will provide or (B) the timing for delivery thereof or (ii Dade is not reasonably satisfied that Hoechst will be able to provide such financial information within the time for delivery of such financial information as set forth on such schedule; (g) by Dade within five Business Days after receipt by Dade of the audited financial statements for the Business for the fiscal year ended December 31, 1995 as contemplated by Section 9.2(a) hereof, if such financial statements reflect a material adverse deviation from the revenues and results of operations set forth in the draft of such financial statements delivered to Dade on or prior to the date of this Agreement; (h) by either Dade or Hoechst, if Dade and Hoechst have not agreed upon the Consent Indemnity Limit prior to the Termination Date pursuant to Section 1.4(b); (i) by Dade on the Valuation Drop Date, if the parties have not agreed upon the Expenditure Agreement pursuant to Section 1.4(c); or (j) by Dade prior to the Termination Date, if Dade and Hoechst have not agreed upon, pursuant to Section 1.4(d), which rights under the Stockholders Agreement shall be Designation Rights.

In the event of termination of this Agreement --------------------- by either Dade or Hoechst as provided above, this Agreement shall forthwith become void and of no further force and effect, except that the covenants and agreements set forth in Sections 3.8, 6.1, 6.2, 7.3, 7.5, 7.8 and 7.14 shall survive such termination indefinitely, and except that nothing in Section 6.1 or this Section 6.2 shall be deemed to release any party from any liability for any breach by such party of -47- the terms and provisions of this Agreement or to impair the right of any party to compel specific performance by another party of its surviving obligations under this Agreement. ARTICLE VII ADDITIONAL AGREEMENTS --------------------- 7.1 Survival of Representations and Warranties.

The representations and warranties in this Agreement shall survive for the periods set forth in this Section 7.1 and shall in no event be affected by any investigation, inquiry or examination made for or on behalf of Dade or Hoechst, or the knowledge of any of the Dade Entities' or the Hoechst Entities' officers, directors, shareholders, employees, agents, or other representatives or the acceptance by Dade or Hoechst of any certificate or opinion hereunder.

Subject to the provisions of ----------------------------------- Section 7.2(g), Hoechst shall indemnify Dade and its affiliates (including affiliates after the Closing), and its and their stockholders, officers, directors, employees, agents, representatives, successors and per mitted assigns (collectively, the "Dade Parties") and save and hold each of them ------------ harmless against and pay on behalf of or reimburse such Dade Parties as and when incurred for any loss, liability, demand, claim, action, cause of action, cost, damage, deficiency, tax, penalty, fine or expense, whether or not arising out of third party claims (including interest, penalties, reasonable attorneys' fees and expenses and all reasonable amounts paid in investigation, defense or settlement of any of the foregoing) (collectively, "Losses"), which any such ------ Dade Party may suffer, sustain or become subject to, as a result of, in connection with, relating or incidental to or by virtue of: (i) subject to Section 7.1, any breach of representation and warranty set forth Article IV of this Agreement without regard to any specified dollar limitations or thresholds set forth in such Article IV (other than such dollar limitations or thresholds set forth in Sections 4.9(f), (g), (i), (j), (k), (o) and (r), 4.14(a)(i), (ii), (iv), (v), (vi), (vii), (ix), (x) and (xi) and 4.15(a)); (ii) any nonfulfillment or breach of any covenant, agreement or other provision by Hoechst under this Agreement; or (iii) any liability or obligation which is an Indemnified Liability (as defined in Section 9.25 herein); provided that Hoechst shall not have any liability under clause (i) above with - -------- respect to any particular breach of representation and warranty (other than pursuant to Sections 4.1, 4.3 and 4.4 (and Section 4.27 to the extent related to the foregoing Sections)) unless the Loss for such item exceeds $250,000 and the aggregate of all Losses relating thereto for which Hoechst would, but for this proviso, be liable exceeds on a cumulative basis an amount equal to $10,000,000, and then only to the extent of any such excess; and provided further that the -------- ------- aggregate amount for which Hoechst shall be liable under clause (i) above shall in no event exceed $100,000,000. Dade shall take and shall cause its affiliates to make a good faith attempt to mitigate all such Losses upon and after Dade becomes aware of any circumstances which could reasonably be expected to give rise to such Losses. (b) Indemnification for Benefit of Hoechst. Dade shall indemnify -------------------------------------- Hoechst and its affiliates (including affiliates after the Closing), and its and their stockholders, officers, directors, employees, agents, representatives, successors and permitted assigns (collectively, the "Hoechst Parties") and save --------------- and hold each of them harmless against and pay on behalf of or reimburse such Hoechst Parties as and when incurred for any Losses that the Hoechst Parties may suffer, sustain or become subject to, as the result of, in connection with, relating or incidental to or by virtue of: -49- (i) subject to Section 7.1, any breach of representation and warranty set forth in Article V of this Agreement without regard to any specified dollar limitations or thresholds set forth in such Article V (other than such dollar limitations of thresholds set forth in Sections 5.9(f), (g), (i), (j), (k), (o) and (r), 5.14(a)(i), (ii), (iv), (v), (vi), (vii), (ix), (x) and (xi) and 5.15(a)); (ii) any nonfulfillment or breach of any covenant, agreement or other provision by Dade under this Agreement; or (iii) payments, liabilities or other obligations under or with respect to the San Jose Sublease. (iv) other than Indemnified Liabilities and other than as otherwise expressly provided in this Agreement, any liability or obligation paid or discharged by Hoechst or any of its affiliates (other than Dade and its subsidiaries) after the Closing (or any related Loss) that arises out of or relates to the ownership, use or operation of the Business or the Business Assets; or (v) except with respect to the $26.9 million face amount of receivables referred to in Section 1.7, any claims by Dade and its affiliates against Hoechst and its affiliates with respect to intercompany accounts referred to in Section 7.17 hereof; provided that the amount of Losses (I) with respect to clause (i) above (other - -------- than Losses relating to Section 5.3 (as it relates to the capital stock of Dade) or 5.4) or for breach of any covenant set forth in Section 3.3, 3.5 or 7.3(b) hereunder (but with respect to 7.3(b) hereunder, only for Losses due to payments made to any Person in excess of the amounts agreed upon by the parties hereto pursuant to Section 7.3(b) hereunder) shall be determined by multiplying, in order to acknowledge in certain cases that Hoechst's Loss may be suffered indirectly as a shareholder of Dade, the Hoechst Percentage times such Losses and (II) with respect to clause (i) above for Losses relating to Section 5.3 (as it relates to the capital stock of Dade) or 5.4 or for breach of any covenant set forth in Section 3.6, 3.7 or 7.19 shall be determined by adding to such Losses an amount equal to the Hoechst Percentage times such Losses; provided -------- further that, Dade shall not have any liability under clause (i) above with - ------- respect to any particular breach of representation and warranty (other than pursuant to Sections 5.1, 5.3 and 5.4 (and Section 5.23 to the extent related to the foregoing Sections)) unless the Loss for such item exceeds $517,000 (determined without applying the Hoechst Percentage to such Losses) and the aggregate of all Losses relating thereto for which Dade would, but for this proviso, be liable exceeds on a cumulative basis an amount equal to $20,769,000 (determined without applying the Hoechst Percentage to such Losses), and then only to the extent of any such excess; and provided further that the aggregate -------- ------- Losses for which Dade shall be liable under clause (i) above shall in no event exceed $207,690,000 (determined without applying the Hoechst Percentage to such Losses). Hoechst shall take and shall cause its affiliates to make a good faith attempt to mitigate all such Losses upon and after Hoechst becomes aware of any circumstances that -50- could reasonably be expected to give rise to such Losses. As used herein, "Hoechst Percentage" shall be determined, in the case of each claim for ------------------ indemnification hereunder, as of the date of written notice of such claim and shall equal the percentage (calculated to the fourth decimal point) obtained by dividing (A) the Basic Percentage, by (B) one minus the Basic Percentage. The "Basic Percentage" shall be determined as of the date of each such written ---------------- notice and shall equal the percentage (calculated to the fourth decimal point) obtained by dividing (x) the aggregate number of shares of Common Stock and Class L Common, Series B, owned by Hoechst at such time (but only to the extent that such Common Stock and Class L Common, Series B, were either acquired by Hoechst at the Closing hereunder or issued to Hoechst prior to the date of such claims upon the exercise of the Warrant), by (y) the total number of shares of Common Stock, Class L Common, Series B, and Class L Common Stock of Dade, par value $.01 per share ("Class L Common"), outstanding at such time plus all options to purchase shares of Common Stock, Class L Common and Class L Common, Series B, that were originally issued to employees of Dade and its affiliates and that are exercisable at such time. For example, if on the date of a written notice (i) Hoechst owned an aggregate of 450 shares of Common Stock and Class L Common, Series B, (80 acquired pursuant to the Warrant, 325 acquired pursuant to this Agreement and 45 acquired by other means) and (ii) an aggregate of 1,200 shares of Common Stock, Class L Common and Class L Common, Series B, were outstanding on a fully diluted basis (950 shares outstanding, vested employee options to purchase 200 shares and other options to purchase 50 shares), then the Basic Percentage would equal 35.2174% (405 / 1,150 = 0.352174) and the Hoechst Percentage would equal 53.8462% (0.35/(1.00 - 0.35) = 0.538462). (c) Manner of Payment. Any indemnification of the Dade Parties or the ----------------- Hoechst Parties pursuant to this Section 7.2 shall be effected by wire transfer of immediately available funds from Hoechst or Dade, as the case may be, to an account designated by Dade or Hoechst, as the case may be, within 15 days after the determination thereof. Any such indemnification payments shall include interest at the Prime Rate from the date any such Loss is suffered or sustained to the date of payment. Notwithstanding the foregoing, if in the good faith judgment of Dade's board of directors Dade's payment of any portion of such Losses in immediately available funds would impose a significant financial burden on Dade, Dade shall have the option to issue for such portion pay-in-kind preferred stock convertible into Common Stock at the Warrant Price (as defined in the Warrant, but calculated on a per share basis), with a cumulative annual dividend rate, determined by an Independent Investment Banker (as defined below), based upon market conditions and for companies with a comparable credit rating, in order to reflect the financial condition of Dade after such Losses so as to give the preferred stock a market value equal upon issuance to its face amount. Any indemnification payments made pursuant to this Agreement shall be deemed to be adjustments to the Purchase Price for tax purposes. The parties acknowledge and agree that a "significant financial burden" (as used in this Section 7.2(c)) would be imposed on Dade in order to pay Losses in cash if, for example, Dade's board of directors determined in its good faith judgment that Dade, after taking into account such payment, should obtain additional credit facilities (or expand existing credit facilities) in order to meet working capital and other business needs in the ordinary course of business and that obtaining such additional credit facilities (or expanding existing credit facilities) -51- would be burdensome to Dade. "Independent Investment Banker" means, for ----------------------------- the purposes of this Section 7.2(c), the remaining investment banking firm from the list of the five highest ranking New York-based investment banking firms (other than Goldman (or any successor or Affiliate)), rated by the gross dollar value of underwritten public offerings lead-managed during the preceding four -calendar - quarter period, after Hoechst and Dade shall each have alternately eliminated one such firm from such list until only one such firm remains. (d) Defense of Third Party Claims. The party which is entitled to be ----------------------------- indemnified under this Section 7.2 (an "Indemnitee") shall promptly give written ---------- notice hereunder to the party required to indemnify under this Section 7.2 (an "Indemnitor") after obtaining notice of any claim as to which recovery may be - ----------- sought against the Indemnitor because of the indemnity in this Section 7.2, describing the claim, the amount thereof (if known and quantifiable), and the basis thereof, in each case to the extent known by the Indemnitee; provided that -------- the failure to so notify an Indemnitor shall not relieve the Indemnitor of its obligations hereunder except to the extent that (and only to the extent that) such failure shall have caused the Losses for which the Indemnitor is obligated to be greater than such Losses would have been had the Indemnitee given the Indemnitor prompt notice hereunder, including any Loss sustained by the Indemnitee because of late notice of claims to its insurance carriers. Any Indemnitor shall be entitled to participate in the defense of any claim of a third party (a "Third Party Claim") giving rise to an Indemnitee's claim for ----------------- indemnification at such Indemnitor's expense, and at its option (subject to the limitations set forth below) shall be entitled to assume the defense thereof and in connection therewith appoint a nationally recognized and reputable counsel reasonably acceptable to the Indemnitee to be the lead counsel in connection with such defense; provided that: -------- (i) the Indemnitee shall be entitled to participate in the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided that the fees and expenses of such separate -------- counsel shall be borne by the Indemnitee (other than any fees and expenses of such separate counsel that are incurred prior to the date the Indemnitor effectively assumes control of such defense which, notwithstanding the foregoing, shall be borne by the Indemnitor); (ii) if the Indemnitor does not assume the defense of such Third Party Claim in accordance with this Section 7.2, the Indemnitee will not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof; provided, however, -------- ------- that if the Indemnitor fails to take reasonable steps necessary to defend diligently such Third Party Claim, the Indemnitee may assume its own defense, and the Indemnitor will be liable for all reasonable costs or expenses paid or incurred in connection therewith; and (iii) if the Indemnitor shall control the defense of any such Third Party Claim, the Indemnitor shall obtain the prior written consent of the Indemnitee (which shall not be unreasonably withheld) before ceasing to defend such Third Party Claim -52- or before entering into any settlement of such Third Party Claim if such settlement does not expressly and unconditionally release, with prejudice, the Indemnitee from all liabilities and obligations with respect to such Third Party Claim. (e) Determination of Losses, etc. The amount of any Losses for which ----------------------------- indemnification is provided under this Section 7.2 shall be (A) increased to take account of any actual net Tax cost incurred by the Indemnitee (or its affiliates) arising from the receipt of indemnity payments hereunder (grossed up for such increase) and (B) reduced to take account of any actual net Tax benefit realized by the Indemnitee (or its affiliates) arising from the incurrence or payment of any such Loss. In computing the amount of any such Tax cost or benefit, the Indemnitee (or its affiliates, if applicable) shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence or payment of any indemnified Losses. Any indemnification payment hereunder shall initially be made without regard to this Section 7.2(e) and shall be reduced to reflect any such net Tax benefit or increased to reflect any such net Tax cost only after the Indemnitee (or its affiliates) has actually realized such benefit or cost. For purposes of this Agreement, an Indemnitee (or its affiliates) shall be deemed to have "actually realized" a net Tax ----------------- benefit or net Tax cost to the extent that, and at such time as, the amount of Taxes payable by such Indemnitee (or its affiliates) is reduced below or increased above, as applicable, the amount of Taxes that such Indemnitee (or its affiliates) would be required to pay but for the receipt of the indemnity payment or the incurrence or payment of such Loss, as the case may be. The amount of Losses for which indemnification is provided under this Section 7.2 shall not include any liabilities and obligations if and to the extent that any such liabilities or obligations have actually reduced Net Assets. (f) Sole Remedy. Except as otherwise expressly provided in this ----------- Agreement, Hoechst and Dade hereby acknowledge and agree that the sole and exclusive remedy of the Hoechst Parties and the Dade Parties with respect to any and all Losses relating to the subject matter of this Agreement shall be pursuant to the indemnification provisions set forth in this Article VII. In furtherance of the foregoing, Dade and Hoechst hereby waive, to the fullest extent permitted under Applicable Law, rights with respect to any and all other Losses they or the other Hoechst Parties or the other Dade Parties may incur relating to the subject matter of this Agreement. Except as set forth in this Agreement, neither Dade nor Hoechst is making any representation, warranty, covenant or agreement with respect to the matters contained herein. Anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of Hoechst or Dade, after the consummation of the purchase and sale of the Stock contemplated hereby, to rescind this Agreement or any of the transactions contemplated hereby. (g) Indemnification in Favor of the GMBH Company or HDHC. If Hoechst ---------------------------------------------------- enters into any agreement (including pursuant to the Restructuring Documents) with the GMBH Company or HDHC prior to the Closing, which agreement provides that Hoechst shall indemnify the GMBH Company or HDHC, as the case may be, for the indemnification obligations of Hoechst -53- with respect to Section 7.4, 7.12, 7.13 or 7.15 or any Indemnified Liability, Dade shall not be entitled to any indemnification from Hoechst under this Agreement if and to the extent that Hoechst shall have indemnified the GMBH Company or HDHC, as the case may be, for such indemnification obligations. It is hereby agreed that such agreements to indemnify the GMBH Company shall cover obligations related to the Acquired Entities located in Europe, other than in the United Kingdom, Switzerland and Turkey (the "European Acquired Entities"), -------------------------- and such agreements to indemnify HDHC shall cover obligations related to the Acquired Entities in any other country, including the United Kingdom, Switzerland and Turkey (the "Non-European Acquired Entities"). ------------------------------ 7.3 Expenses. -------- (a) Hoechst will pay all taxes, costs, expenses and other obligations incurred or payable (i) in connection with the transactions contemplated by the Restructuring Documents and which taxes, costs, expenses and other obligations are necessary to incur in connection with such transactions as described therein or (ii) in connection with other transactions necessary to otherwise separate the Business from Hoechst and its affiliated companies (including in connection with transfers in or out of the Acquired Entities, whether before or after Closing). In no event shall such taxes, costs, expenses and other obligations include any liabilities if and to the extent that any such liabilities reduced the amount of Net Assets. (b) Upon the consummation of the transactions contemplated herein (and, with respect to Hoechst (and its affiliates), only upon such consummation), Dade shall pay (or reimburse Hoechst (or its affiliates), as the case may be) for all third-party, out-of-pocket fees, costs and expenses of Hoechst's (or its affiliates') and Dade's advisors for services rendered in connection with the Combination Documents, including investment advisors, accountants, lawyers and consultants, if any, subject to any prior agreements of the parties hereto as to the amount of any particular fees, costs and expenses; provided that such payments shall be limited to activities directly related to - -------- the business combination contemplated hereby, such as due diligence and negotiations, but excluding, with respect to Hoechst and the Business, audits, other ordinary course activities and the transactions, agreements and arrangements referred to in Section 7.3(a) above. To the extent that on or prior to the Closing Hoechst has paid to any third-party any amount with respect to any such fees, costs or expenses for which Dade is obligated to pay pursuant to the foregoing, the amount of such payments by Hoechst shall be credited to the Net Assets as of the Closing subject to receipt by Dade of reasonable and appropriate documents for such fees, costs and expenses. (c) Hoechst (with respect to the Business) and Dade (with respect to Dade) will cooperate and use reasonable best efforts to obtain all requisite third party Consents with respect to Contracts necessary to consummate the transactions contemplated by the Combination Documents, but neither party will be required to pay more than $2 million (exclusive of attorney and other advisor fees) to third parties in connection therewith. -54- (d) In addition to all fees, costs and expenses contemplated by Sections 7.3(a) and 7.3(c) above and other than those contemplated by Section 7.3(b) above, Hoechst shall also pay all transfer taxes, filing fees and other costs and expenses in connection with the transfer of the Business to Dade; provided that such transfer taxes (other than German real estate transfer - -------- taxes), filing fees and other costs are not in excess of $750,000, with all amounts exceeding such limit to be paid by Dade; and provided further that -------- ------- expenditures made by Hoechst pursuant to this Section 7.3(d) which are not required in connection with the transfer of the Business shall not be utilized in computing such $750,000 limitation, unless Dade shall have approved such expenditure by Hoechst, which approval shall not be unreasonably withheld. Filing fees contemplated by Section 3.7 hereunder and the Transfer Taxes set forth in Section 7.4(e) hereunder, to the extent paid in connection with the transfer of the Business to Dade, are subject to the terms of this Section 7.3(d). 7.4 Tax Matters. ----------- (a) Taxable Periods Ending on or Before the Closing Date. Hoechst ---------------------------------------------------- shall prepare and file, or cause to be prepared and filed, at Hoechst's expense, all Tax Returns for the Acquired Entities for all taxable periods ending on or prior to the Closing Date which are filed after the Closing Date. Hoechst shall permit Dade to review and comment on each such Tax Return described in the preceding sentence prior to filing. Hoechst shall pay all income Taxes of the Acquired Entities with respect to taxable periods ending on or before the Closing Date. Hoechst shall be entitled to all income Tax refunds for Acquired Entities for all taxable periods ending on or prior to the Closing Date. Dade shall pay Hoechst any such refund amounts within 15 days of Dade, its affiliates', or Acquired Entities' receipt of the same. (b) Taxable Periods Beginning Before and Ending After the Closing ------------------------------------------------------------- Date. Dade shall prepare and file, or cause to be prepared and filed, any Tax Returns of the Acquired Entities for taxable periods which begin before the Closing Date and end after the Closing Date. Dade shall permit Hoechst to review and comment on each such Tax Return described in the preceding sentence prior to filing. Hoechst shall pay to Dade or the Acquired Companies within 15 days of the date on which income Taxes are paid with respect to such periods an amount equal to the portion of such income Taxes which relates to the portion of such taxable period ending on the Closing Date to the extent such income Taxes have not been paid on or before the Closing Date. For purposes of this Section 7.4(b), in the case of any income Taxes that are payable for a taxable period that includes (but does not end on) the Closing Date, the portion of such income Tax which relates to the portion of such taxable period ending on the Closing Date shall be deemed to be equal to the amount of income Taxes which would have been payable if the relevant taxable period ended on the Closing Date. Any income Tax refunds for taxable periods which begin before the Closing Date and end after the Closing Date shall be apportioned as described in this Section 7.4(b). Dade, its affiliates, and the Acquired Entities and Hoechst and its affiliates shall file for such refunds and fully cooperate to obtain the same. Dade shall pay Hoechst any refund amount due Hoechst under this Section 7.4(b) within 15 days of Dade's, its affiliates', or Acquired Entities' receipt of the same. Hoechst shall bear a portion of the costs of preparing and filing the Tax Returns governed by this -55- Section 7.4(b), such portion to be equal to the portion of the Tax shown on such Tax Return for which Hoechst is liable under this action. For purposes of Sections 7(a) and 7(b), an "income Tax" includes any Tax based on or measured in ---------- whole or in part by income. (c) Additional Tax Indemnification. In addition to the Taxes ------------------------------ allocated to Hoechst under Sections 7.4(a) and 7.4(b) above, Hoechst shall be liable for, and shall indemnify and hold Dade, its affiliates, and the Acquired Entities harmless against, without duplication, (i) any Taxes arising out of the transactions contemplated in the Restructuring Documents; and (ii) all liability (whether as a result of Treasury Regulation (S) 1.1502-6, or any similar provision of state, local, or foreign law, as a transferee, by contract, or otherwise) for Taxes of any Person based on an affiliation, contractual relationship or other relationship existing between such Person and any Acquired Entity at any time prior to the Closing. In no event shall such Taxes or liabilities include any liabilities if and to the extent that such liabilities reduced the amount of Net Assets. (d) Cooperation on Tax Matters. Dade and its affiliates and Hoechst -------------------------- and its affiliates shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Section 7.4, or any amended return, claim for refund, determining a liability for Taxes or a right to refund of Taxes, or any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to any such return, analysis, audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Acquired Entities and Hoechst and its other affiliates agree (A) to retain all books and records with respect to tax matters pertinent to the Acquired Entities relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Dade or Hoechst, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Acquired Entities or Hoechst and their affiliates, as the case may be, shall allow the other party to take possession of such books and records. (e) All sales and transfer taxes, recording charges and similar taxes, fees or charges imposed as a result of any of the transactions contemplated in the Restructuring Documents or this Agreement (collectively, the "Transfer -------- Taxes"), together with any interest, penalties or additions to such Transfer Taxes shall be paid by Hoechst. In no event shall such Transfer Taxes, interest, penalties or additions include any liabilities if and to the extent that any such liabilities reduced the amount of Net Assets. Hoechst and Dade shall cooperate in timely making or causing their affiliates to make all filings, returns, reports and forms as necessary or appropriate to comply with the provisions of all Applicable Laws in connection with the payment of such Transfer Taxes, and shall cooperate in good faith to minimize, to the fullest extent possible under such laws, the amount of any such Transfer Taxes payable in connection therewith. -56- 7.5 Confidentiality. Any information provided to Hoechst or its affiliates --------------- by or on behalf of Dade and to Dade or its affiliates by or on behalf of Hoechst pursuant to this Agreement shall be held by Hoechst, Dade and their respective affiliates in accordance with, and shall be subject to the terms of, certain Confidentiality Agreements, dated October 17, 1996 and February 25, 1997, each by and between Hoechst and Dade (the "Confidentiality Agreements"), which are -------------------------- hereby incorporated in this Agreement with the same effect as though fully set forth herein. 7.6 Covenant Not to Compete. ----------------------- (a) As an inducement for Dade to consummate the transactions contemplated by the Combination Documents, Hoechst agrees that for a period (the "Non-Competition Period") beginning on the Closing Date and ending on the later ---------------------- of (x) the third anniversary of the Closing Date and (y) the earlier of (A) the date on which Hoechst no longer has (or, if Dade so requests, Hoechst waives) all of its rights under paragraph 1 of the Stockholders Agreement and such other provisions of the Stockholders Agreement, if any, as agreed to pursuant to Section 1.4(d) (the "Designation Rights"), and (B) the date on which Dade ------------------ terminates the Cooperation Agreement, it shall not (other than in its capacity as a stockholder of Dade and for the benefit of Dade in connection with the Transition Services Agreement), and it shall not permit any of its affiliates after the Closing to, directly or indirectly, either for itself or through any other Person, engage in, participate in, or permit its name to be used by any enterprise engaging in or participating in, any aspect of the human in vitro diagnostics business in any part of the world; provided, however, that nothing -------- ------- herein shall prohibit Hoechst or its affiliates from (i) participating in any activity contemplated by the Cooperation Agreement, (ii participating in a joint venture with any Person provided that the joint venture is not in competition -------- with Dade in the human in vitro diagnostics business, and (ii acquiring any Person or entering into any business combination with any Person or entering into any joint venture in each case which is engaged in the human in vitro diagnostics business but in which the human in vitro diagnostics business is not the primary business of such Person or joint venture so long as Hoechst, in good faith, offers to sell such business to Dade and if, the parties cannot agree on a price, the price shall be the fair market value determined by an Independent Investment Banker. If Dade does not purchase such human in vitro diagnostics business, Hoechst shall enter into an agreement to sell such business to an independent third party within one year after Dade declines to purchase such human in vitro diagnostics business and shall consummate such sale within two years after Hoechst's acquisition of such human in vitro diagnostics business. For purposes of this Agreement, the term "participation" includes any direct or ------------- indirect interest in any enterprise, whether as a stockholder, partner, joint venturer, franchisor, franchisee or otherwise (other than by ownership of less than five percent (5%) of the stock of a publicly held corporation). Hoechst agrees that this covenant is reasonably designed to protect Dade's substantial investment in the Business and is reasonable with respect to its duration, geographical area and scope. The restrictions set forth in this Section 7.6(a) shall terminate upon the seventh anniversary of the Closing Date. -57- (b) Prior to the later of (i) two years after the Closing Date and (ii one year after the date as Hoechst shall no longer have the Designation Rights, neither Hoechst nor any of its affiliates will solicit the employment (in any capacity) of, or, to the extent not otherwise prohibited by Applicable Law, hire, any employee of Dade or any of its affiliates (other than any employee whose employment is terminated by Dade or such affiliate) without the prior written consent of Dade (which consent shall not be withheld capriciously or otherwise without a good business reason). Notwithstanding the foregoing, nothing herein shall prohibit Hoechst from hiring Uwe Bicker in any capacity not otherwise prohibited in any agreement between Uwe Bicker and Dade or any of its affiliates. (c) Prior to two years after the date of this Agreement, neither Dade nor its affiliates (including the Acquired Entities after Closing) will solicit the employment (in any capacity) of, or, to the extent not otherwise prohibited by Applicable Law, hire any employee of Hoechst or any of its affiliates (other than an employee of InfraServ or whose employment is terminated by Hoechst or such affiliate), with whom Dade or any of its affiliates has had contact or who became known to Dade or any of its affiliates in connection with the consideration and consummation of the transactions contemplated by this Agreement, without the prior written consent (which consent shall not be withheld capriciously or otherwise without a good business reason) of Hoechst. (d) Prior to one year after the date on which the Cooperation Agreement shall have been terminated, neither Dade nor its affiliates (including the Acquired Entities after Closing) will solicit the employment (in any capacity) of, or, to the extent not otherwise prohibited by Applicable Law, hire any employee of Hoechst or any of its affiliates (other than an employee of InfraServ or whose employment is terminated by Hoechst or such affiliate), with whom Dade or any of its affiliates will have had contact or who becomes known to Dade or its affiliates in connection with the transactions contemplated by the Cooperation Agreement, without the prior written consent (which consent shall not be withheld capriciously or otherwise without a good business reason) of Hoechst. (e) If, at the time of enforcement of any of the provisions of this Section 7.6, a court (or arbitrator or administrator) determines that the restrictions stated herein are unreasonable under the circumstances then existing, then the parties hereto agree that the maximum period, scope or geographical area reasonable under the circumstances shall be substituted for the stated period, scope or area. The parties further agree that such court (or arbitrator or administrator) shall be allowed to revise the restrictions contained herein to cover the maximum period, scope or geographical area permitted by law. In no event shall any such substituted or revised period, scope or geographical area exceed any restrictions set forth in Sections 7.6(a) and 7.6(b). (f) If Hoechst, Dade or any of their respective affiliates after the Closing (the "Restricted Persons") breaches, or threatens to commit a breach of, ------------------ any of the provisions of this Section 7.6 (the "Restrictive Covenants"), Dade or --------------------- Hoechst, as the case may be, shall have, -58- independent of any other rights and remedies under this Agreement, the right and remedy to have the Restrictive Covenants specifically enforced by any court of competent jurisdiction without the need to post bond or other security, it being agreed that any breach or threatened breach of the Restrictive Covenants would cause irreparable injury to the parties hereto and that money damages would not provide an adequate remedy to such party. 7.7 Further Transfers; Further Assistance. ------------------------------------- (a) Hoechst shall (whether prior to or after the Closing) execute and deliver such further instruments of conveyance and transfer and take such additional action as Dade may reasonably request to effect, consummate, confirm or evidence the transfer of the Stock to Dade, the transfer of the Business Assets to the Acquired Entities and the conduct of the Business by the Acquired Entities after the Closing (including with respect to obtaining and maintaining all Permits and other Consents necessary or desirable in connection therewith), and shall execute such documents as may be necessary to assist Dade in preserving or perfecting its rights in the Stock after giving effect to the Closing, and the Acquired Entities in preserving or perfecting their rights in the Business Assets or their ability to conduct the Business. Without limiting the foregoing, after the Closing, (i) Hoechst shall (and shall cause its affiliates to) promptly forward to Dade any and all proceeds from accounts receivable relating to the Business or the Business Assets that are received by Hoechst or its affiliates after the Closing but which are part of the Business Assets or which otherwise are for the account of Dade or its affiliates and (ii) Dade shall (and shall cause its affiliates to) promptly forward to Hoechst any and all proceeds from accounts relating to the business or assets (other than the Business or the Business Assets) that are received by Dade or its affiliates after the Closing but which are part of such business or assets or which otherwise are for the account of Hoechst or its affiliates. In connection with any transfer of Business Assets pursuant to this Section 7.7(a), no Hoechst Entity shall transfer any liabilities (of the kind used in calculating Net Assets), whether or not related to the Business, in excess of the amount of current assets (of the kind used in calculating Net Assets) transferred therewith. (b) Without limiting the foregoing, to the extent that the assignment by the Hoechst Entities to one of the Acquired Entities of any Contract pursuant to the Restructuring Documents is not permitted or is prohibited by any Governmental Entity or is not permitted without the consent of any other party to such Contract, neither the Restructuring Documents, this Agreement nor any other Combination Document shall be deemed to constitute an assignment of any such Contract if such consent is not given or if such assignment otherwise would constitute a breach of, or cause a loss of contractual benefits under, any such Contract, and Hoechst will take such provisions as to ensure that no Acquired Entity shall assume or be liable for any obligations or liabilities under any such Contract. Hoechst shall (and shall cause the Other Hoechst Entities to) use their reasonable efforts to advise Dade promptly in writing with respect to any such Contract which any Hoechst Entity knows or has reason to believe will or may not be subject to assignment to one of the Acquired Entities pursuant to the Restructuring Documents. If any Consent with respect to any Contract is not obtained or if such assignment is not permitted irrespective of consent -59- and the Closing hereunder is consummated, Hoechst shall (and shall cause the Other Hoechst Entities to) cooperate with Dade following the Closing Date in any reasonable arrangement designed to provide Dade with the rights and benefits (subject to the obligations) under any such Contract, including, at Hoechst's expense (but subject to the limit on payments to third parties as set forth in Section 7.3(c) herein), enforcement for the benefit of the Acquired Entities of any and all rights of the Hoechst Entities against any other party arising out of any breach or cancellation of any such Contract by such other party and, if requested by Dade, acting as an agent on behalf of the Acquired Entities or as Dade shall otherwise reasonably require. 7.8 Arbitration. ----------- (a) Procedure. At the election of Dade or Hoechst, by written --------- delivery to the other party, any dispute or controversy to which Dade and Hoechst are the principal parties arising out of or relating to the provisions of this Agreement or any of the other Combination Documents (a "Dispute") shall ------- be determined in accordance with the arbitration procedures set forth in this Section 7.8, except as otherwise provided herein (including Section 1.6 above). The parties hereby agree and acknowledge that, except as otherwise provided in this Section 7.8 or otherwise in the Combination Documents, the arbitration procedures and any Final Arbitration Determination (as defined below) hereunder shall be governed by, and shall be enforced pursuant to, the Commercial Arbitration Rules (as supplemented by its Supplementary Procedures for Large, Complex Disputes) of the American Arbitration Association as in effect from time to time. All arbitration proceedings shall be held in New York, New York. (b) Notice of Arbitration. In the event that Dade or Hoechst asserts --------------------- that there exists a Dispute, Dade or Hoechst, as the case may be, shall deliver a written notice to the other party specifying the nature of the asserted Dispute and requesting a meeting to attempt to resolve the same. If no such resolution is reached within 10 calendar days after delivery of such notice, Dade or Hoechst, as the case may be, may, within 45 Business Days after delivery of such notice, commence arbitration hereunder by delivering to the other party a notice of arbitration (a "Notice of Arbitration"). Such Notice of Arbitration --------------------- shall specify the matter(s) as to which arbitration is sought, the nature of any Dispute, the claim(s) of Dade or Hoechst, as the case may be, with respect to the arbitration and shall specify the amount and nature of any damages sought to be recovered as a result of the claim. (c) Selection of Arbitrators. Dade, on the one hand, and Hoechst, on ------------------------ the other hand, shall each select one independent arbitrator expert in the subject matter of the Dispute (the arbitrators so selected shall be referred to herein as "Dade's Arbitrator" and "Hoechst's Arbitrator," respectively). In the ----------------- -------------------- event that either Dade or Hoechst fails to select an independent arbitrator as set forth herein within 30 calendar days from delivery of a Notice of Arbitration, then the matter shall be resolved by the arbitrator selected by the other. Hoechst's Arbitrator and Dade's Arbitrator shall select a third independent arbitrator expert in the subject matter of the dispute, and the three arbitrators so selected shall resolve the matter according to the procedures set forth in this Section -60- 7.8. If Hoechst's Arbitrator and Dade's Arbitrator are unable to agree on a third arbitrator within 20 calendar days after their selection, Hoechst's Arbitrator and Dade's Arbitrator shall each prepare a list of three independent arbitrators expert in the subject matter of the Dispute. Hoechst's Arbitrator and Dade's Arbitrator shall each have the opportunity to designate as objectionable and eliminate one arbitrator from the other arbitrator's list within 7 calendar days after submission thereof, and the third arbitrator shall then be selected by lot from the arbitrators remaining on the lists submitted by Hoechst's Arbitrator and Dade's Arbitrator. (d) Costs. The cost of arbitration ("Arbitration Cost") shall be paid ----- ---------------- by Hoechst, subject to the reimbursement by Dade as set forth in the next sentence. If any of the items set forth in the Notice of Arbitration are resolved by the arbitrator in favor of Hoechst, Dade shall promptly reimburse Hoechst by wire transfer of immediately available funds in an amount equal to (the "Arbitration Reimbursement Calculation") (if and only if a positive number) ------------------------------------- the Arbitration Cost multiplied by a factor equal to A minus B plus twice A ----- ---- multiplied by B; where "A" is the quotient obtained by dividing the amount of - ---------- the items in the Notice of Arbitration resolved by the arbitrator in favor of Hoechst by the total amount of such items, and "B" is the Hoechst Percentage. (e) Entry of Award. The arbitrator(s) shall conduct the arbitration -------------- such that a final result, determination, finding, judgment and/or award (a "Final Arbitration Determination") is made or rendered as soon as practicable, - -------------------------------- but in no event later than 90 calendar days after the delivery of the Notice of Arbitration nor later than 10 calendar days following completion of the arbitration. The Final Arbitration Determination must be agreed upon and signed by the sole arbitrator or by at least two of the three arbitrators (as the case may be). The Final Arbitration Determination shall be final and binding on the parties and there shall be no appeal from or reexamination of the Final Arbitration Determination, except for fraud, perjury or misconduct by an arbitrator prejudicing the rights of any party, and to correct manifest clerical errors. (f) Enforcement. Dade and Hoechst may enforce any Final Arbitration ----------- Determination in any court of competent jurisdiction. If a party makes the Section 7.8(a) arbitration election after the other party has instituted a lawsuit (including a third-party suit) regarding the same Dispute, the other party shall terminate the lawsuit (except the portion, if any, seeking the relief permitted under Section 9.11) and the Dispute shall be resolved pursuant to this Section 7.8. (g) Other Remedies. Nothing in this Section 7.8 shall be construed to -------------- impair the right of either party to seek injunctive or other equitable relief pursuant to Section 9.11. 7.9 Use of Current Supplies and the Hoechst Name. Dade will have after -------------------------------------------- the Closing in Inventory a quantity of work-in-process, preprinted stationery invoices, receipts, forms, advertising and promotional materials, training and source literature, packaging material and other supplies (including all Inventory acquired by Dade) which bear Hoechst's or any Other Hoechst Entity's name and logo. To the extent legally permissible, Hoechst hereby grants, and shall cause the Other Hoechst Entities to grant, to Dade a paid-up license, to remain in effect until the exhaustion of such -61- Inventory in the ordinary course of business, to use any trademarks, trade names, trade dress, copyright or other proprietary rights of Hoechst associated with such Inventory. Dade agrees to use reasonable best efforts to exhaust such Inventory in the ordinary course of business as soon as is reasonably practicable after the Closing. Such license shall be in addition to other licenses granted hereunder or under the documents entered into in accordance with the terms of this Agreement and the Restructuring Documents. Except as provided in this Section 7.9 and as set forth in the Restructuring Documents, no interest in or right to use the name "Hoechst" or the name of any Other Hoechst Entity (other than the Acquired Entities) or any derivation thereof or any trademark, trade name or trade dress with respect thereto is being transferred to Dade pursuant hereto. Within 20 Business Days after the Closing, Dade shall change the name of each Acquired Entity whose name currently includes "Hoechst" so as to remove the "Hoechst" name therefrom. Notwithstanding anything in this Section 7.9 or the Restructuring Documents to the contrary, for a period of three (3) years after the Closing, Dade shall have the right to use the name "Hoechst" in connection with the renamed Acquired Entities located in Japan, Singapore, China and Korea by stating, in whatever form or medium, that each such Acquired Entity is a "Hoechst Joint Venture" or a "Hoechst Diagnostics Joint Venture." 7.10 Change of Structure. Notwithstanding anything to the contrary in this ------------------- Agreement, if Dade or Hoechst proposes an alternative structure for the transfer of the Business to Dade from that contemplated in this Agreement, and such alternative structure does not adversely affect the Tax or accounting consequences, allocation of liabilities, marketability of securities in the public markets, valuation of enterprise or any other economic considerations related to the transfer of the Business, Hoechst and Dade agree to negotiate in good faith to modify (or cause their affiliates to modify), to the extent legally permissible, the Restructuring Documents, this Agreement and the other Combination Documents in such ways as are necessary to implement such alternative structure. For purposes of this paragraph, alternative structures which may be considered include (i) the acquisition of Acquired Entities directly by Dade or its wholly owned subsidiaries, (ii) the acquisition of Business Assets directly by Dade or its subsidiaries, and (iii) making elections under Section 338 (or, if applicable, Section 338(h)(10)) of the Code (or any similar provision of state, local or foreign Tax law) with respect to any Acquired Company or Acquired Entity. 7.11 Transition Countries. Without limiting the provisions of Section 7.7 -------------------- and in furtherance thereof, if by the Closing Date, Dade and Hoechst or their respective affiliates have not received regulatory clearance in one or more countries to close the transactions contemplated by the Combination Documents (a "Transition Country"), it is agreed that Hoechst shall, directly or indirectly, ------------------ on and after the Closing Date, and during the period from the Closing Date until receipt of regulatory clearance in the country (the "Transition Phase"), carry ---------------- on that part of the Business as agent and trustee and for the account of Dade and its affiliates (after the Closing Date) in accordance with the following provisions: (a) Hoechst shall within 30 days after the end of each calendar month of the Transition Phase, and also within 30 days after the end of the Transition Phase, prepare, or cause to -62- be prepared, an account for the Business in each Transition Country, showing for each such calendar month or other period: (i) All receipts received by Hoechst and its affiliates; and (ii) All out-of-pocket expenses incurred by Hoechst and its affiliates directly relating to the Business, other than pursuant to arrangements otherwise contemplated by the Transition Services Agreement. The account shall show the net difference between (i) and (ii), and shall be accompanied by payment of the difference to Dade if (i) is greater than (ii), or an invoice to Dade for the difference if (ii) is greater than (i), which invoice Dade shall pay within ten (10) days after receipt. (b) Any comments or objections which Dade may have with respect to the accounts rendered for that Transition Country under Section 7.11(a) above shall be discussed promptly between Dade and Hoechst. If such comments or objections result in the matter under discussion being resolved, then any appropriate amendment shall be made to such account and Dade and Hoechst shall account to each other accordingly. If such comments or objections do not result in such resolution, then the matter in dispute shall be dealt with in the manner outlined in Section 7.8. (c) If any claim which is covered by insurance of Hoechst or any of its affiliates shall arise during the Transition Phase in respect of any of the Business Assets relating to a part of the Business carried on in a Transition Country, Hoechst shall promptly submit, or cause to be submitted, all relevant documents to the insurers to substantiate such claim in trust for Dade and turn over the proceeds to Dade. Hoechst shall promptly inform Dade of the circumstances giving rise to such insurance claim. (d) Except as otherwise provided in this Agreement, Dade shall have sole liability and responsibility for and in respect of all employees, if any, in each Transition Country (the "Transition Employees") on and after the -------------------- Closing, and Dade shall indemnify or, cause its affiliates (after the Closing) to indemnify, Hoechst and its affiliates (after the Closing), and keep them indemnified in respect thereof. To facilitate an orderly transition of the relevant part of the Business in each Transition Country, during the Transition Phase, Hoechst or its affiliates (after the Closing) shall continue to employ the Transition Employees, and, in consideration thereof, except as otherwise provided in this Agreement with respect to such employees, Dade or its affiliates (after the Closing) shall fully reimburse Hoechst and its affiliates (after the Closing) the cost of the salary, benefits, and all other payments payable to or liabilities in respect of the relevant Transition Employees incurred with respect to the Transition Phase. All such sums so payable shall be regarded as payment of expenses in respect of the Business within the meaning of Section 7.11(a)(ii) above, and shall be reflected in the account(s) rendered for the relevant Transition Country. Except as otherwise provided in this Agreement, no liabilities shall attach to Hoechst or its affiliates (after -63- the Closing) in respect of any of such Transition Employees, who shall be the sole responsibility of Dade and its affiliates (after the Closing), and over whom Dade and its affiliates (after the Closing) shall have full management and supervisory responsibility from and after the Closing. 7.12 U.S., Europe and Japan Restructuring Expenses. Hoechst will fund, as --------------------------------------------- incurred, all costs and expenses relating to the restructuring plans previously disclosed to Dade and its representatives for the categories of expenses set forth on the attached U.S./Europe/Japan Restructuring Expenses Schedule. To the ------------------------------------------------- extent the restructuring plans are not completed prior to Closing Date, Dade will complete, at Hoechst's expense, such plans in a manner consistent with such restructuring plans and will consult with Hoechst from time to time in implementing such restructuring plans. The parties agree that the amounts set forth on the U.S./Europe/Japan Restructuring Expenses Schedule are provided for informational purposes only and that the actual costs and expenses to be funded by Hoechst may be more or less than the amounts set forth thereon. 7.13 Italy Manufacturing Facility Restructuring Expenses. Hoechst shall --------------------------------------------------- complete, at its sole expense, the planned shutdown (the "Italian Facility ---------------- Shutdown") of the Italy manufacturing facility. Hoechst hereby agrees to pay - -------- for all costs, obligations and liabilities arising from or directly related to such Italian Facility Shutdown. 7.14 Break-Up Fee. If this Agreement is terminated because the condition ------------ set forth in Section 2.1(n) shall not have been satisfied, Dade will promptly, but in no event later than three Business Days after this Agreement has been terminated due to the failure of such condition, pay Hoechst $25 million in immediately available funds via wire transfer. Hoechst and Dade hereby agree that the payment of such fee is a material inducement to Hoechst to enter into this Agreement and is to compensate Hoechst for the opportunity costs and risks of entering into this Agreement. 7.15 SEP Liability. Certain employees and former employees of the Syva ------------- division of the Business are covered by the Special Employment Program ("SEP") --- which provides certain severance and termination payments in the event conditions set forth in the SEP are satisfied. Hoechst hereby agrees to indemnify HDHC from all Losses arising out of or in connection with SEP. Hoechst will have full responsibility for handling all claims or potential claims, including all decisions relating to payment thereof, and will reimburse HDHC for all out-of-pocket and other costs and expenses (including mutually agreeable charges for employee time, facilities, document production, legal fees, etc.). Prior to January 1, 1998, Dade agrees to comply with the agreements set forth on the attached SEP Schedule with a view to mitigating ------------ Hoechst's exposure with respect to SEP. Hoechst agrees to make available to Dade all available information, including reports generated with regard to SEP and those benefits sought by Continued Employees under SEP, and, at the reasonable request of Dade, will meet periodically with Dade to provide additional information. 7.16 Proprietary Rights Filing Expenses. Hoechst shall prepare and file (or ---------------------------------- shall cause to be prepared and filed) all documents necessary or desirable for, and shall bear all costs associated with, recording in the applicable patent, trademark and copyright offices the GMBH Company's -64- ownership interest in those patents, trademarks and copyrights included among the Proprietary Rights, including the recording of the assignments of patents and trademarks from Syva Co. and Syntex (USA) Inc. 7.17 Assignment of Intercompany Accounts. Hoechst shall assign immediately ----------------------------------- prior to Closing (a) to the GMBH Company the net balance of all intercompany receivables less intercompany payables of Hoechst and its consolidated affiliates on the one hand and the European Acquired entities on the other hand and (b) to HDHC the balance of all intercompany receivables and intercompany payables of Hoechst and its consolidated affiliates on the one hand and the Non- European Acquired Entities on the other hand, in accordance with following: (i) Hoechst shall cause to be assigned to Hoechst all intercompany receivables on the books of its fully consolidated subsidiaries (other than the Acquired Entities) as of the Closing against each of the Acquired Entities.

Hoechst shall deliver to Dade a schedule of the ---------- PBO calculations with respect to each Hoechst Pension Plan along with such other information which is necessary for Dade to verify such results.

Interest shall be added to the PBO Shortfall amount at the Prime Rate from the Closing Date to the date the cash payment is made. In the event the sum of the PBO Shortfalls is less than $26.9 million, Dade shall cause a cash payment to be made to Hoechst equal to the difference between $26.9 million and the sum of the PBO Shortfalls.

The lease of such parcel shall be rent- free for an initial period of twenty (20) years and shall thereafter have a fair market rental which amount per square meter shall be no greater than the lowest land parcel rental charged to any other site resident for comparable parcels of land.

Hoechst hereby covenants and agrees that as soon as practicable after the Closing, but in no event later than October 31, 1997, Hoechst will cause the current owner(s) and/or lessee(s) (the "Japan Landlord") to enter into -------------- a written lease agreement with Dade or a subsidiary of Dade for the manufacturing premises currently used and occupied by the Business in Japan (the "Japan Premises"), on the following terms and conditions: -------------- Term: Two (2) year initial term, with right of the GMBH Company to ---- terminate upon a notice to be agreed upon. Rent: Historical 1996 rent. ---- Other: All other terms and conditions as currently exist between the Japan ----- Landlord and the Business, and the other standard terms and conditions for such lease agreements in Japan. 14.

In the event Hoechst Italia is not the sole owner of the Scoppito Land or the Scoppito Land is substantially larger than the parcel necessary for the full use and enjoyment of the building occupied by Istituto Behring (the "Behring Building") or other buildings and ---------------- improvements are located on the Scoppito Land, and in any of the foregoing cases the Scoppito Land cannot be appropriately subdivided, then Istituto Behring shall receive a long-term lease or other comparable property rights to that part of the Scoppito Land necessary for the full use and enjoyment of the Behring Building by Istituto Behring, which lease or other property rights shall be comparable to a mortgage free, fee simple ownership interest (e.g. a 999 year lease). Hoechst shall cause Hoechst Italia and Dade shall cause Istituto Behring to agree on reasonable rights of way, easements and similar mutual encumbrances to allow both Hoechst Italia and Istituto Behring to use and develop their adjoining land.
