If and when an Event of Impasse has occurred, the Board of Directors shall promptly appoint an Impasse Committee of three members. One member shall be selected by CTI, one by Siemens, and the third by the first two members; in the event that the members selected by CTI and Siemens cannot mutually agree upon a third member, such member shall be selected by counsel for CTI and Siemens. It shall be the responsibility of the Impasse Committee to arrive unanimously at a resolution of the Event of Impasse. The resolution recommended by the Impasse Committee shall be binding on the parties hereto (1) unless it is rejected by a majority of the members of the Board of Directors of Group, in which event the Board will then either (A) resolve the impasse, (B) appoint another Impasse Committee (provided, however, that no more than two (2) Impasse Committees may be appointed for any given Event of Impasse), or (c) recommend that CTI or Siemens buy out the other's Group Common Stock interest on mutually agreeable terms, and (2) provided that a recommendation by the Impasse Committee of a buyout by either Group or Siemens of the other shall not be binding on the parties. 13.8 CTI Board.

In the event that additional capital investment is needed by Group in accordance with a business plan approved by its Board of Directors, then CTI and Siemens will each contribute such capital in proportion to their ownership of Group Common Stock, unless another option, e.g., borrowing, is mutually agreed by CTI and Siemens. If either is unable or refuses to make such capital contribution, then Group shall issue sufficient shares of Group Common Stock at fair market value, determined in the manner provided in Sections 14.1 and 14.2 hereof to raise the necessary capital. The other Group shareholder which has contributed its share of the necessary capital shall have a right of first refusal to purchase such shares. 13.10 Intercompany Transfers. The parties acknowledge that it is the intention of Management that CTI develop businesses involving products and services related to the CPS Business, either directly itself, or through subsidiaries or other Affiliates. Siemens and CPS understand and agree that CTI and its Affiliates may use CPS products for the establishment of its own distribution centers for positron-emitting radioisotopes and compounds, for its own PET diagnostic centers, and for the other purposes contemplated in Section 12.1. The parties further agree that with respect to the development of Qualified Distribution Centers, CTI or its Affiliates may purchase RDS (radioisotope distribution systems) products, including any improvements and advances thereto, directly from CPS on the same terms and conditions on which Siemens purchases from CPS pursuant to the OEM Exclusive Distribution Rights Agreement among CPS, Management and Siemens, at prices equal to the transfer prices set forth on Exhibit 13.10 hereto. For purposes of this Section, a "Qualified Distribution Center" shall be a location owned by CTI or its Affiliates, for which CTI can demonstrate a commitment, expressed in writing, by at least one unrelated third party, for the purchase of positron-emitting radioisotopes and compounds from such Distribution Center. CPS products, including RDS products, not purchased for Qualified Distribution Centers shall be purchased from Siemens or its Affiliates at prices to be negotiated on a case by case basis. For centers which they own and operate, CTI or its Affiliates may purchase ECAT systems directly from Siemens and its Affiliates at prices to be negotiated on a case by case basis. All CPS products sold pursuant to this Section 13.10 shall not be resold by CTI in competition with CPS, Siemens or customers of Siemens or its Affiliates. 13.11 Business Plan. Attached hereto as Exhibit 13.11 is a copy of the current five-year business plan for CPS which states the expected sales, expenses and investment levels for CPS, including proportions of debt and equity, together with an expectation range. Exhibit 13.11 is for reference only, and has not been approved by CTI and Siemens. As soon as practicable following the Closing, an initial annual business plan shall be developed and adopted for Group and CPS. 13.12 Distribution Agreement. At the Closing, CPS, Management and Siemens will enter into and execute an amendment of the May 20, 1986 OEM Exclusive Distribution Rights Agreement among them to add thereto additional products of CPS. The form of the amendment shall be substantially as set forth in Exhibit 4.5(j) hereto. -27- <PAGE> 14. ADDITIONAL PURCHASE AND SALE RIGHTS. 14.1 Siemens' Additional Purchase Rights. Siemens shall have the right from and after the Closing Date to purchase from CTI additional shares of Group Common Stock up to the number of shares of Group Common Stock required to bring Siemens' ownership of Group Common Stock to eighty percent (80%) of the then issued and outstanding capital stock of Group at such time (or thereafter) as any of the following events shall occur: (a) A change in control of CTI incident to which Management does not continue to hold, in the aggregate, more shares of CTI Common Stock than any other single shareholder other than Siemens or any of its Affiliates, unless the prior written consent of Siemens is obtained, which consent shall not be unreasonably withheld; or (b) From and after five (5) Years from the date hereof, at such time as the dollar sales volume of CTI's business, other than the CPS Business, is greater than the dollar sales volume of CPS; or (c) From and after seven (7) years from the date hereof, provided, however, (1) Siemens' additional purchase right described in this Section 14.1 shall be contingent upon CPS having exceeded the number of aggregate units required to be sold from the date hereof to the date of exercise of such purchase right as specified in the "Siemens minima plus 20% plan" attached hereto as Exhibit 14.1 in the year immediately preceding its election to exercise its purchase right, (2) CTI shall have a one-time right to defer the exercise of such right by Siemens for a period of one year after the initial notice of exercise, i.e., upon Siemens' initial notice of its intent to exercise its right to purchase additional shares of Group Common Stock hereunder, CTI shall have the right to decline to sell such shares to Siemens, and Siemens may not again undertake to exercise such right to purchase additional shares of Group Common Stock for one year after the initial notice of exercise which was so declined, and (3) Siemens' additional purchase right described in this Section 14.1 shall be contingent on approval from the Bundeskartellamt office in the Federal Republic of Germany, which approval shall be sought in good faith by Siemens. The price to be paid for the Group Common Stock pursuant to such purchase right shall be a price to be negotiated by Siemens and CTI, provided, however, that in the event that they cannot agree upon a price within sixty (60) days from the date of effective notice of exercise, the price shall be determined by the following appraisal procedure: Each party shall obtain a valuation of the Group Common Stock by an independent professional experienced in the valuation of closely-held corporations similar to Group. If the valuations thus obtained are within twenty percent (20%) of each other, the price to be paid for the Group Common Stock to be purchased from CTI by Siemens shall be the average of the two valuations. If the difference between the valuations is more than twenty percent (20%), the two parties making those valuations shall select a third independent professional experienced in the valuation of closely-held corporations similar to Group to make a valuation, and the price to be paid for the Group Common Stock to be purchased by Siemens from CTI shall be the average of the two of the three valuations which are the closest to each other. 14.2 CTI's Additional Rights. CTI shall have the right from and after the Closing to require Siemens to purchase from CTI additional shares of Group Common Stock up to the number of shares of Group Common Stock required to bring Siemens' ownership of -28- <PAGE> Group Common Stock to eighty percent (80%) of the then issued and outstanding capital stock of Group at such time (or thereafter) as any of the following events shall occur: (a) A change in control of CTI incident to which Management does not continue to hold, in the aggregate, more shares of CTI Common Stock than any other single Shareholder other than Siemens or any of its Affiliates, unless the prior written consent of Siemens is obtained, which consent shall not be unreasonably withheld; or (b) From and after five (5) years from the date hereof, at such time as the dollar sales volume of CTI's business, other than the CPS Business, is greater than the dollar sales volume of CPS; or (c) From and after seven (7) years from the date hereof, provided, however, (1) CTI's additional sale right described in this Section 14.2 shall be contingent upon CPS having exceeded the number of aggregate units required to be sold from the date hereof to the date of exercise of such sale right as specified in the "Siemens minima plus 20% plan" attached hereto as Exhibit 14.1 in the year immediately preceding its election to exercise its sale right, (2) Siemens shall have a one-time right to defer the exercise of such sale right for a period of one year after the initial notice of exercise, i.e., upon CTI's initial notice of its intent to exercise its right to require Siemens to purchase additional shares of Group Common Stock, Siemens shall have the right to decline to purchase such shares, and CTI may not again undertake to exercise such right to require Siemens to purchase additional shares of Group Common Stock for one year after the initial notice of exercise which was so declined, and (3) CTI's additional purchase right described in this Section 14.2 shall be contingent on approval from the Bundeskartellamt office in the Federal Republic of Germany, which approval shall be sought in good faith by Siemens. The price to be paid for the Group Common Stock pursuant to such purchase right shall be a price to be negotiated by Siemens and CTI, provided, however, that in the event they cannot agree upon a price within sixty (60) days from the date of effective notice of exercise, the price shall be determined by the following appraisal procedure: Each party shall obtain a valuation of the Group Common Stock by an independent experienced in the valuation of closely-held corporations similar to Group. If the valuations thus obtained are within twenty percent (20%) of each other, the price to be paid for the Group Common Stock to be purchased by Siemens from CTI shall be the average of the two valuations. If the difference between the valuations is more than twenty percent (20%), the two parties making those valuations shall select a third independent professional experienced in the valuation of closely-held corporations similar to Group to make a valuation, and the price to be paid for the Group Common Stock to be purchased by Siemens from CTI shall be the average of the two of the three valuations which are the closest to each other. 14.3 Purchase and Sale in Event of Default. For purposes of this Section 14.3, an "Event of Default" shall be deemed to have occurred if and when any of the following shall have occurred, and shall not have been cured within thirty (30) days after written notice thereof given to the defaulting party by the non-defaulting party: (a) Any representation or warranty herein made by Siemens on the one hand or CTI, Group, CPS or Management on the other proves to have been false in any material respect when made; -29- <PAGE> (b) CTI or Siemens (or any Affiliate of Siemens holding Group shares) files a bankruptcy petition, makes a general assignment for the benefit of creditors or has an involuntary bankruptcy petition filed against it; or (c) CTI or Siemens is unwilling or unable to provide additional capital to Group in accordance with a previously approved plan or previously approved commitment to do so. Upon the occurrence of an Event of Default as defined hereinabove, the non-defaulting shareholder of Group shall have the right to (A) name its designees to any or all management positions of Group without liability to any displaced person under any management or employment contract, and (B) name an additional representative to the Board of Directors of Group. The non-defaulting party will immediately be relieved of any contractual requirements in any management or employment contracts and may administer a sale of additional Group Common Stock to provide previously committed funds, such sales to occur at fair market value in accordance with the procedure set forth at Sections 14.1 and 14.2 above. The non-defaulting shareholder shall have the right to purchase such additional Group Common Stock at its fair market value for sixty (60) days after determination of the price of the shares. 15. STOCK TRANSFER RESTRICTION AND RIGHT OF FIRST REFUSAL. The provisions of this Section 15 shall apply at and after the Closing. Neither CTI nor Siemens may transfer its Group Common Stock for a period of five (5) years from the Closing Date; provided, however, that Siemens or CTI may during such time transfer such stock to any Affiliate of Siemens or CTI, so long as such transfer does not violate any applicable securities laws, subject to the provisions of Section 22.2 below. After five (5) years from the Closing Date, if CTI or Siemens contemplates a sale of its Group Common Stock, it shall notify the other stockholder, and they shall attempt to agree upon a price pursuant to which the other stockholder may purchase the Group Common Stock of the selling stockholder. If they cannot agree upon a price, then the selling stockholder's Group Common Stock shall be subject to a right of first refusal in favor of the other stockholder, as provided hereinbelow, which right of first refusal shall survive after any transfer to a third party. If Siemens or CTI or any of their permitted transferees (the "Selling Stockholder") desires to sell any of its Group Common Stock to any party other than (A) an Affiliate of Siemens or CTI, (B) any general or limited partnership in which Siemens or CTI, or an Affiliate of Siemens or CTI, is a partner, or (C) any Management Person, then: 15.1 The Selling Stockholder shall give notice to the other stockholder of any transactions covered by this Section 15. The notice shall include (A) the name, address and principal business activity of the prospective purchaser; (B) the number of shares of stock proposed to be sold; (C) the manner in which the sale is proposed to be made (including the proposed closing date); and (D) the price at which, or other consideration for which, and the material terms upon which, such sale is proposed to be made, and stating that such proposed sale is, to the best of the Selling Stockholder's knowledge, bona fide. 15.2 During the thirty (30) day period commencing on the date the other stockholder receives the Selling Stockholder's notice, the other stockholder shall have the right to acquire all but not less than all of the shares of Group Common Stock proposed to be sold by the Selling Stockholder in such transaction. Such right shall be exercised, if at all, by an -30- <PAGE> irrevocable notice of exercise given by the other stockholder and received by the Selling Stockholder prior to the expiration of such period, accompanied by a statement that the other stockholder shall pay the Selling Stockholder in accordance with the terms provided for in the proposed transaction. 15.3 If the other stockholder exercises its rights under this Section 15, the Selling Stockholder shall deliver certificates duly endorsed for transfer representing the shares of Group Common Stock purchased by the other stockholder in accordance with the terms specified in such notice against receipt of payment therefor. 15.4 The closing shall occur on the date specified in the Selling Stockholder's notice. 15.5 If the conditions prescribed in this Section 15 have been met in connection with the proposed sale of Group Common Stock by the Selling Stockholder and the other stockholder has not elected to exercise its right of first refusal hereunder, then the Selling Stockholder shall be free to effect such sale for a period of one hundred eighty (180) days following the date of the notice given under Section 15.1 hereof, but only to the person or persons specified in such notice and at the price (or for the consideration) and on substantially the same terms specified therein, and if such sale does not occur within such 180 day period, Group Common Stock proposed to be sold will continue to be subject to this Agreement to the same extent as if such notice had not been given. 16. SALE OF CTI COMMON STOCK BY MANAGEMENT. So long as Siemens owns one percent (1%) or more of the issued and outstanding CTI Common Stock, and provided that at such time there has been no public offering of CTI Common Stock, if at any time any Management Person wishes to sell any of his CTI Common Stock, he shall first notify both Siemens and CTI of his intention to do so, to enable them to offer competitive bids for his CTI Common Stock, provided, however, that this Section 16 shall not be construed as a right of first refusal or a requirement that the Management Person sell his shares to Siemens or CTI. 17. SPECIFIC PERFORMANCE. The parties recognize that, because of the nature of the subject matter of this Agreement, it would be impracticable and extremely difficult to determine actual damages in the event of a breach of this Agreement. Accordingly, if any party commits a breach, or threatens to commit a breach, of any of the provisions of Sections 2, 3, 4, 9, 10, 11, 12, 13, 14, 15 or 16 the other parties shall have the right to seek and receive a temporary restraining order, injunction or other equitable remedy, including, without limitation, the right to have the provisions of this Agreement specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury and that money damages will not provide an adequate remedy. 18. DISPUTE RESOLUTION. Except with respect to resolution of events of impasse, for which a separate procedure is set forth at Section 13.7 above, the parties agree to resolve amicably and in good faith any disputes arising from the interpretation of any provisions of this Agreement. In the event of any disagreement among the parties concerning any provision hereof upon the request of any party the matter shall be immediately referred to the managements of Siemens and CTI. If within a period of 30 days after reference of the matter to them the respective managements are unable to agree upon a resolution, any party may within 30 days after the aforesaid 30-day period elect to utilize a non-binding resolution procedure whereby each party presents its case at a hearing held in Chicago, -31- <PAGE> Illinois or Knoxville, Tennessee, on an alternating basis, with the first hearing to be held in Chicago, Illinois, before a panel consisting of the Chief Executive Officer of each of Siemens and CTI and a mutually acceptable neutral advisor, who shall be selected from the Center for Public Resources' Judicial Panel. Prior to the hearing, the parties and the neutral advisor shall agree on a set of ground rules for the hearing. At the conclusion of the hearing, the Chief Executive Officers of each of Siemens and CTI shall meet and attempt to resolve the matter. If the matter cannot be resolved at such meeting, the neutral advisor may be called upon to render his opinion as to how the matter would be resolved had the matter been on trial in a court of law. After the opinion is received, the executives shall meet again and try to resolve the matter. If the matter cannot be resolved at such meeting, any party may give to the other party notice of its intention to litigate. No litigation may be commenced concerning the matter in dispute until 60 days have elapsed from the sending of the notice to litigate; provided, however, that such litigation may be commenced prior to such date if the applicable statute of limitations would run prior thereto. The parties shall bear their respective costs incurred in connection with this procedure, including the fees and expenses of the neutral advisor. Only after the foregoing procedure has been exhausted shall either party resort to litigation as the final adjudication of the dispute. 19. PRODUCT LIABILITY. Management shall cause CTI at the Closing to enter into an agreement to hold Siemens harmless against any and all product liability, including but not limited to, personal injuries and property damages, recovered by any claimant relating to products manufactured or sold by Group or CPS before the Closing Date, including but not limited to products in the inventories of Group and CPS at the Closing Date, plus any attorney's fees incurred by Siemens in connection with such a claim, provided that CTI shall not be responsible for liability on such products in the event that the damages or injuries which resulted in such liabilities shall be the result of alterations, repairs or service on products, shipment or installation of the products or other action relating to such products by or on behalf of Siemens after the Closing Date. The responsibility of CTI under this Section shall extend to products which Group or CPS did not manufacture but which were sold by or on behalf of Group or CPS prior to the Closing Date. 20. PENSION AND EMPLOYEE BENEFIT MATTERS. Group, CPS and Siemens shall comply with the provisions of the benefits plans listed on Exhibit 5.21 attached hereto and all the laws applicable thereto. 21. TERMINATION OF THIS AGREEMENT. 21.1 Termination. This Agreement may be terminated before the Closing occurs only as follows: (a) By written agreement of the parties at any time; (b) By Siemens, by notice to other parties at any time, if satisfaction of one or more of the conditions specified in Section 4.5 is or becomes impossible; (c) By Group or Management, by notice to Siemens at any time, if satisfaction of one or more of the conditions specified in Section 4.6 is or becomes impossible; or (d) By any of the parties by notice to the others at any time after March 15, 1988. -32- <PAGE> 21.2 Effect of Termination. In the event that this Agreement is terminated pursuant to Section 21.1, such termination shall be without any liability or further obligation of any party to another and the obligations and agreements in this Agreement shall terminate and have no further effect, except for liabilities and obligations (a) under Sections 22.1 and 22.8 hereof, which shall survive such termination, or (b) based on any intentional failure to perform or comply with any covenant or agreement herein or for any intentional misrepresentation or breach of any warranty herein which causes Damages, and such termination shall not constitute a waiver of any claim with respect thereto. 22. MISCELLANEOUS. 22.1 Expenses. Except as otherwise provided herein, Management shall cause CTI to pay, on the one hand, and Siemens shall pay, on the other hand, the expenses incurred in connection with this Agreement and the transactions contemplated hereby by CTI, Group, CPS, the Non-Siemens Group Shareholders and Management, in the first case, and Siemens, in the second case. The payment of all transfer taxes and documentary taxes (other than those imposed by jurisdictions outside the United States) which may be imposed upon each transaction shall be paid by CTI at each closing with respect to the securities transferred in proportion to their interest in the securities transferred. 22.2 Successors; Assignment. This Agreement shall be binding upon and shall inure to the benefit of and be enforceable by the successors of the parties hereto. Except as otherwise provided herein, this Agreement shall not be assignable. Each of Siemens and CTI shall have the right to transfer all or any of the Group Common Stock owned by it to any Affiliate of Siemens or CTI, respectively; provided, however, that such Affiliate of Siemens or CTI, as the case may be, shall agree in advance in writing to be bound by all the terms of this Agreement. In such case, the Affiliate of Siemens shall be entitled to enforce as against CTI, Group, CPS and Management all of the terms and conditions of this Agreement to the same extent as this Agreement could be enforced by Siemens, but Siemens shall remain bound by the terms of this Agreement, and the Affiliate of CTI shall be entitled to enforce as against Siemens all of the terms and conditions of this Agreement to the same extent as this Agreement could be enforced by CTI or Management, but CTI and Management shall remain bound by the terms of this Agreement. 22.3 Entire Agreement; Amendment. This Agreement and the exhibits hereto set forth the entire understanding between the parties with respect to their respective subject matters. They may not be modified, amended, altered or supplemented and no provision may be waived except by a written agreement signed by the parties thereto which shall be authorized by all necessary corporate action of each party. 22.4 Survival of Representations, Warranties and Covenants; Indemnification. (a) All representations, warranties, covenants and agreements made herein shall survive the execution and delivery of this Agreement and the purchase and sale of the Group Common Stock provided for hereunder. (b) If the Closing occurs, each of CTI and Management, on the one hand, and Siemens, on the other hand, shall indemnify and hold the others and Group harmless from and against all Damages arising from or in connection with: -33- <PAGE> (1) any misrepresentation or breach of any warranty made by it herein or in any Exhibit delivered by it at the Closing pursuant hereto or attached hereto; (2) any breach or non-fulfillment of any covenant or agreement required to be performed by it hereunder or thereunder; and (3) any and all actions, suits, investigations, proceedings, demands, assessments, judgments, costs and legal and other expenses incidental to any of the foregoing; provided, however, that CTI and Management shall each be obligated to indemnify and hold harmless Siemens in connection with their own respective misrepresentations, breach or non-fulfillment only; it is not intended that CTI or Management be responsible for the other's misrepresentations, breach or non-fulfillment. Notwithstanding anything to the contrary herein, none of CTI, Management or Siemens shall be required so to indemnify and hold harmless with respect to the first U.S. $50,000 in Damages in the aggregate for which it is liable under this section. In determining the amount of Damages for purposes of this Section, (y) notwithstanding anything to the contrary herein, neither Siemens nor Management or the Non-Siemens Group Shareholders shall have any liability for indemnification hereunder with respect to any claim resulting from the events described in this section of which the indemnifying party is unaware unless a notice of claim, in reasonable detail, with respect thereto shall have been given to the indemnifying party with sufficient promptness after the indemnified party becomes aware of the relevant facts pertaining to such claim that the indemnifying party's ability to minimize or eliminate such Damages has not been materially adversely affected by delay; and (z) no Damages shall be deemed sustained to the extent that such Damages are covered by insurance for the benefit of the indemnified party. (c) Procedure -- Each indemnified party shall give notice to the indemnifying party of any claim hereunder with reasonable promptness after obtaining knowledge thereof, including, without limitation, any third party claim against the indemnified party or Group which might give rise to a claim against the indemnifying party hereunder, stating the nature and basis of such claim and the amount thereof, in reasonable detail, to the extent then known by the indemnified party. The indemnified party shall keep the indemnifying party fully informed, use all reasonable efforts to defend such claim or litigation and present any defense reasonably suggested by the indemnifying party or its counsel. The indemnifying party shall have the right to participate in such third-party claim or litigation by counsel and accountants, at its own expense, and, upon notice to the indemnified party, to assume, at its own expense, the defense or prosecution thereof, as the case may be, with counsel approved by the indemnified party (which approval shall not be unreasonably withheld). If the indemnifying party assumes such defense or prosecution, it shall have no liability for any legal or other expenses subsequently incurred by the indemnified party in connection with such proceeding other than the reasonable costs of investigation and cooperation with the indemnifying party in such defense or prosecution, but it shall thereafter indemnify and hold the other, the other's Affiliates and Group -34- <PAGE> harmless from all Damages with respect to such claim or litigation. The indemnified party shall not make, or offer to make, any settlement of any claim or litigation which might give rise to a right of indemnification from the indemnifying party, without the consent of such indemnifying party, which consent shall not be unreasonably withheld. 22.5 Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given by personal delivery, cable, telegram or telex, or by mail (registered or certified mail, postage prepaid, return receipt requested) to the respective parties as follows: If to Group: CTI Group, Inc. 810 Innovation Drive Knoxville, Tennessee 37932 Attention: Terry D.
