Until so surrendered, each certificate shall be deemed at any time after the Effective Time to represent only the right to receive the amount of cash, without interest, into which Gull Shares theretofore represented - 6 - by such certificate shall have been converted at the Effective Time pursuant to this Section. If a certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed and, if required by Meridian or Gull, upon the posting by such Person of a bond in such amount as Meridian or Gull may reasonably direct as indemnity against any claim that may be made against it with respect to such certificate and upon such Person's compliance with the other requirements set forth herein, the Paying Agent will issue in respect of such lost, stolen or destroyed certificate, the Merger consideration to be received by virtue of the Merger with respect to Gull Shares represented thereby. 2.5.2 Meridian may cause the Paying Agent to invest the payment fund in securities of a United States commercial bank or of the government of the United States or any state thereof, provided, that the terms and conditions of the investments shall be such as to permit the Paying Agent to make prompt payment of the Merger consideration as necessary.

Each Party will give prompt written notice to the others of any material adverse development causing a breach of any of its own representations and warranties in Section Section 3, 4 and 5.

Each of Fresenius and Gull will not, and will not cause or permit any of its employees or agents to, solicit, initiate, or encourage the submission of any proposal or offer from any Person relating to a tender or exchange offer, a merger, consolidation or other business combination involving Gull or any of its Subsidiaries or any proposal to acquire in any manner a substantial equity interest in, or substantial portion of the assets of, Gull or any of its Subsidiaries (a "Third Party Offer"); provided, however, that Fresenius, Gull and their respective directors and officers may engage in discussions or negotiations with, or furnish information concerning Gull and its properties, assets and business to any Person which makes a Third Party Offer if the Board of Directors of Gull reasonably concludes in good faith after consultation with, and based on the advice of, its outside counsel, that the failure to take such action would be inconsistent with the fiduciary obligations of such Board of Directors under applicable law; and provided further, that notwithstanding anything to the contrary herein contained, the Board of Directors of Gull may take and disclose to Gull Stockholders a position contemplated by Rule 14e-2 promulgated under the Securities Exchange Act, comply with Rule 14d-9 thereunder and make all disclosures required by applicable law in connection therewith and such actions shall not be considered a breach of - 31 - this Section of this Agreement.

Gull shall afford Meridian two business days to respond with a counteroffer to any Third Party Offer.

Any such payment will be made promptly in immediately available United States funds. 6.9 Bylaw Indemnification. The Bylaws of Gull, as the surviving corporation, shall contain the provisions with respect to indemnification set forth in the Articles of Incorporation and Bylaws of Gull on the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of five years after the Effective Time in any manner that would adversely affect the rights thereunder of Persons who at any time prior to the Effective Time were prospective indemnitees under the Articles of Incorporation or Bylaws of Gull in respect of actions or omissions occurring at or prior to the Effective Time, including, without limitation, the transactions contemplated by this Agreement, unless such modification is required by law. For a period of five years after the Effective Time, Meridian will reimburse Fresenius for its actual out-of-pocket costs for the maintenance of "tail coverage" of Gull's officers and directors pursuant to Fresenius' existing insurance policy covering such matters to the extent that such coverage may be purchased with premium payments for such tail coverage established as of the Closing Date or Meridian may, at its option, maintain such coverage with a United States nationally-recognized insurer. 6.10 Closing Balance Sheet.

Covenants of Fresenius; Indemnification. 7.1 Voting of Shares.

Fresenius shall not be obligated to vote such shares in favor of the Merger if the Fairness Opinion is withdrawn for reasons other than the appearance of a Third Party Offer. In addition, Fresenius shall not be obligated to vote such shares in favor of the Merger if the Fairness Opinion is withdrawn because of the appearance of a Third Party Offer, but in such case Fresenius will pay to Meridian the entire amount of consideration received by Fresenius in excess of $11,094,059 through the consummation of a transaction pursuant to such Third Party Offer. Fresenius will retain ownership and all voting rights to the Gull Shares owned by it through the closing. 7.2 Indebtedness of Gull to Fresenius. Upon the closing of the Merger all amounts then owed by Gull to Fresenius will be reduced by a contribution by Fresenius to the capital of Gull to the extent of any reductions in the shareholders' equity of Gull that occurs from December 31, 1997 through the Closing Date. Any remaining amounts owed by Gull to Fresenius, including accrued interest, will be represented by a note of Meridian payable to Fresenius to the extent of 50% of the principal on June 15, 1999 and the balance on December 31, 1999 together in each case with interest on the unpaid balance at 7 1/2% per annum. Should the reduction in shareholders' equity, including without limitation reductions established through Section Section 6.11.2 and 6.11.3, exceed the aforesaid amounts owed by Gull to Fresenius, the balance will be paid to Meridian by Fresenius at the closing and at the time of determination provided in Section Section 6.11.2 and 6.11.3. Fresenius will continue to finance Gull through the closing of the Merger in amounts and to the extent and on terms and conditions consistent with Fresenius' past practices in financing Gull. The amount of any such reduction in the shareholder's equity shall be as determined by the balance sheet prepared as of the Closing Date as called for in Section 6.10. Should the parties not agree on the closing balance sheet, any areas of disagreement shall be resolved by an accounting firm jointly picked by the accounting firms that audited Gull's and Meridian's last annual financial statements. 7.3 Indemnification for Shareholder Actions. Fresenius will indemnify and hold harmless Meridian and Gull, and their officers, directors, employees, agents and Subsidiaries from and against any and all claims and demands brought by Gull Stockholders or Fresenius shareholders against any of them with respect to matters arising prior to the Closing Date including, without limitation, the matters contemplated by this Agreement, other than amounts paid by Meridian or Gull to dissenting Gull Stockholders and expenses incurred in related appraisal proceedings. The obligations of Fresenius will be limited to $11,094,059. Meridian will indemnify and hold harmless Fresenius and Gull, and their officers, directors, employees, agents and Subsidiaries from and against any and all claims and demands brought by Meridian shareholders against any of them with respect to the matters contemplated by this Agreement including, without limitation, with respect to information provided by Meridian in writing for inclusion in the proxy statement of Gull for submission to Gull Stockholders to vote upon the Merger. The obligations of Meridian will be limited to $3 million. 7.3.1 Promptly after receipt by an indemnified party of written notice of the commencement of any action or proceeding threatened or initiated with respect to which a claim for indemnification is to be made pursuant to this - 35 - Section, the indemnified party will give written notice to the indemnitor of the commencement of such action; provided the failure to give notice shall not relieve the indemnitor of its obligations hereunder except to the extent that the indemnitor is actually prejudiced by such failure to give notice. Unless in the indemnified party's reasonable judgment a conflict of interest between the Persons indemnified and the indemnitor may exist in respect of the claim, the indemnitor shall be entitled to participate and to assume the defense of such claim, jointly with any other such claim to the extent that it may desire with counsel reasonably satisfactory to the indemnified party as the case may be. After notice from the indemnitor of its election to assume the defense thereof, the indemnitor will not be liable to the Persons indemnified for any legal or other expenses subsequently incurred by them in connection with the defense thereof. The indemnitor will not consent to the entry of any judgment or enter into any settlement which does not include as an unconditional term given by the claimant or plaintiff to the Persons indemnified, a release from all liability with respect to such claim or litigation. The indemnitor shall not be liable for any settlement of any such claim or action effected without its written consent. 7.3.2 If the matters giving rise to indemnification stated above become subject to a final judgment of a court of competent jurisdiction which allocates the relative liability for payment of any such claims or demands by shareholders of Fresenius, Gull or Meridian, the liability that would otherwise be that of an indemnitor shall instead be allocated among Fresenius, Gull or Meridian. The allocation will be in such proportions as is appropriate to reflect the relative fault of the particular parties in connection with the statements or omissions or actions or inactions which resulted in such claims or damages of third parties, as determined in such final judgment. 7.4 Indemnification by Fresenius. Fresenius shall indemnify Meridian with respect to and hold Meridian harmless from any liability, cost or expense which Gull or Meridian may directly or indirectly incur or suffer by reason of, or which results from, arises out of or is based upon the inaccuracy of any representation, warranties of and failures to comply with covenants made by Fresenius or Gull herein. Without limiting the generality of the foregoing, the indemnity obligation of Fresenius with respect to the representations of Gull contained in Section 3 shall extend to all representations and warranties of Gull as stated in Section 3 and not be limited to those of which Fresenius has actual Knowledge. This indemnity shall also cover any liabilities, costs or expenses reasonably incurred which Gull or Meridian may directly or indirectly incur or suffer by reason of, or which result from, or arise out of, or are based upon a bankruptcy matter pending in Germany entitled Gull GmbH v. Bamphi, a notice given Gull by INCSTAR Corporation on June 5, 1996 relating to patents dealing with Epstein Barr Virus and with respect to certain validation questions described in Section 3.26 of the Disclosure Schedule, in each case to the extent that such liability, cost or expense exceeds the amount accrued therefor on the closing balance sheet called for by Section 6.10. The indemnification granted by Fresenius with respect to representations and warranties and failures to comply with covenants made by, Gull, is not intended to be a guarantee or surety but rather the direct, unqualified and - 36 - continuing obligation of Fresenius in its capacity as a majority shareholder of Gull extended to Meridian as an inducement for Meridian to enter into and perform this Agreement in reliance in part upon the representations, warranties and covenants of Gull and in consideration of the representations and covenants made by Meridian herein. The parties recognize that it would be inequitable if the obligation of Fresenius, as set forth in this Section 7.4, were construed as a guarantee or surety so as to limit the ability of Meridian to proceed directly against Fresenius as provided hereafter. Accordingly, the parties acknowledge that Meridian may proceed against Fresenius in accordance with this Section 7.4 as provided below, with or without proceeding against Gull or any of its Subsidiaries. Fresenius shall not assert or exercise any, and hereby waives and disclaims all, rights of subrogation, indemnification or contribution by Gull or Meridian with respect to any payments made by it to Meridian pursuant to this Section. Fresenius agrees not to raise as a defense in any proceeding pursuant to this Section 7.4 as provided hereafter or in any other court or forum, any defense to the actions of Meridian based upon a theory that the indemnifications provided herein by Fresenius are in the nature of a guarantee or surety.

The indemnitor shall have 10 business days from receipt of such notice to notify the indemnified party whether or not the indemnitor disputes its obligation to indemnify the indemnified party with respect to such liability. If such notice is not given by the indemnitor, the indemnitor shall pay the amount claimed promptly. 7.7.3 Nothing shall prevent the indemnified party from making a claim with respect to a potential or contingent liability provided the indemnified party's notice sets forth a specific basis for any such potential or contingent liability and the estimated amount thereto to the extent then feasible and the indemnified party has reasonable grounds to believe that such a liability or impairment will be incurred or suffered. Any payment to an indemnified party with respect to any such potential or contingent liability shall be final and binding upon the indemnified party, regardless of the actual losses incurred by the indemnified party in respect of such liability when actually asserted or incurred. 7.7.4 The indemnified party and the indemnitor shall attempt in good faith to resolve any dispute between them with respect to the matters covered by this Section promptly by negotiations between executives that have the authority to settle the dispute. Either party may give the other written notice of any dispute not resolved in the normal course. Within 10 business days following delivery of any such notice, executives of both parties shall meet at a mutually acceptable time and place thereafter for as long as they deem necessary to exchange relevant information and to attempt to resolve the dispute. If the matter has not been resolved within 20 business days following delivery of such notice or if the parties fail to meet within 10 business days, either party may initiate mediation of the dispute. Mediation shall take place under the then current model procedure for mediation of business disputes at the American Arbitration Association, 140 W. 51st Street, New York, New York 10020. A neutral third party will be selected from the Association's panel. The place of mediation shall be New York City. Any dispute not resolved by mediation within 45 days after the initiation shall be settled by arbitration conducted expeditiously in accordance with the rules for arbitration of business disputes conducted by the American Arbitration Association by a sole arbitrator. If one party has requested to the other to participate in the procedures - 38 - outlined above and the other has failed, the other may initiate arbitration before expiration of the 45 day period. Arbitration shall be governed by the United States Arbitration Act and judgment upon the award rendered by the arbitrator may be entered by any court having jurisdiction. 7.8 Transition. Fresenius will not take any action to discourage any lessor, licensor, customer, supplier, or other business associate of any of Gull and its Subsidiaries from maintaining the same business relationships with Gull and its Subsidiaries after the Closing Date as it maintained with them prior to the Closing Date. Fresenius will refer all customer inquiries relating to the businesses of Gull and its Subsidiaries to Meridian from and after the Closing Date. Fresenius will perform in all material respects all agreements now in force between it and Gull or any of its Subsidiaries until and after the Closing Date in accordance with the terms of any such agreements. Fresenius will transmit to Meridian any adverse reaction, adverse experience or quality complaints pertaining to the Products coming to Fresenius' attention after the Closing addressed to Meridian at the address set forth hereafter. 7.9 Confidentiality. Fresenius will treat and hold as such all of the Confidential Information, refrain from using any of the Confidential Information except in connection with this Agreement, and deliver promptly to Meridian or destroy, at the request of Meridian, all tangible embodiments of the Confidential Information which are in its possession. If Fresenius is requested or required to disclose any Confidential Information, Fresenius will notify Meridian promptly at the request or requirement so that Meridian may seek an appropriate protective order or waive compliance with the provisions of this Section. If, in the absence of a protective order or the receipt of a waiver hereunder, Fresenius is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal, Fresenius may disclose the Confidential Information; provided, however, that Fresenius shall use its reasonable efforts to obtain, at the reasonable request of Meridian, an order or other assurance that confidential treatment will be accorded to such portion of the Confidential Information required to be disclosed as Meridian shall designate. The foregoing provisions shall not apply to any Confidential Information which is generally available to the public immediately prior to the time of disclosure. 7.10 Noncompetition and Non-Solicitation Covenants. For a period of three years after the Closing Date, Fresenius will not initiate a new business venture or acquire any business which is predominantly engaged in the manufacture and sale of diagnostic testing kits and reagents in the same field of application as existing Gull or Meridian products (hereinafter referred to as "Prohibited Business") in any geographic area in which Gull and its Subsidiaries or Meridian and its Subsidiaries conducts that business as of the Closing Date, or solicit directly or indirectly or encourage any person employed by Gull or any Subsidiary or Meridian to leave such employment when Gull or Meridian desires to retain that employee. However, notwithstanding the foregoing, this Section 7.10 shall not prevent or prohibit Fresenius from any of the following: - 39 - (i) acquiring another business that is not predominantly engaged in the Prohibited Business; and (ii) distributing any products which are or may be competitive with products manufactured or sold by Gull or Meridian. If Fresenius acquires another business pursuant to subsection (i) above which is also engaged in the Prohibited Business, Fresenius shall use its best efforts to notify Meridian of such acquisition and to enter into discussions with Meridian regarding possible business arrangements with respect thereto acceptable to both Fresenius and Meridian. If the final judgment of a court of competent jurisdiction declares that any term or provision of this Section is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed. 7.11 Contribution to Capital. Fresenius shall release its invoice dated June 30, 1998 in an amount of 856,281.18 German Marks evidencing its claim against Gull for the reimbursement of certain costs and expenses incurred by Fresenius on behalf of Gull by contributing such obligation to the capital of Gull prior to the closing. 8.
