(ii) The Management Stockholder agrees that, notwithstanding any provision in this Agreement to the contrary, he or she will not, without the prior written consent of the Board, during the period following an Initial Public Offering or any secondary registered equity offering during which the Majority Stockholders are subject to underwriter-imposed restrictions on the transfer of shares of Common Stock (the “Lock-Up Period”), (A) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any Shares, Options or other securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by such Management Stockholder in accordance with the rules and regulations of the Securities and Exchange Commission) or (B) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (A) or (B) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, provided that such restrictions shall be no more onerous than those applicable to the Majority Stockholders.

6

3(b)(i) for at least six (6) months, to purchase from the Management Stockholder or the Management Stockholder’s Transferee, and upon the exercise of such right the Management Stockholder or such Transferee shall sell to the Company (or its designated assignee), all or any portion of the Shares held by the Management Stockholder or Transferee as of the date as of which such right is exercised at a per Share price equal to the Fair Market Value of a share of Common Stock determined as of the date such right is exercised, provided that if such termination of the Management Stockholder’s Employment occurs due to the Management Stockholder’s death or Disability or is effected by the Company without Cause or by the Management Stockholder for Good Reason, the call right described in this paragraph (i) shall not apply with respect to such Management Stockholder’s Rollover Shares.

(ii) In the event that either the Management Stockholder’s Employment with the Company is terminated for Cause or the Management Stockholder violates any of the restrictive covenants set forth in the Plan or in any equity award grant agreement under the Plan:

(A) in either case prior to the Agreement Termination Date, the Company (or its designated assignee) shall have the right, during the 180-day period following the latest to occur of (x) such termination of Employment, (y) such violation of a restrictive covenant and (z) the date on which the Management Stockholder or Transferee has held the Shares most recently acquired to be sold pursuant to this Section 3(b)(ii) for at least six (6) months, to purchase from the Management Stockholder or the Management Stockholder’s Transferee, and upon the exercise of such right the Management Stockholder or such Transferee shall sell to the Company (or its designated assignee), all or any portion of the Shares held by the Management Stockholder or Transferee as of the date as of which such right is exercised at a per Share price equal to (I) in the case of a Rollover Share, the Fair Market Value of such Share determined as of the date such right is exercised or (II) in the case of an Option Share, the lesser of (a) the Fair Market Value of a share of Common Stock determined as of the date such right is exercised or (b) the exercise price per Share paid by the Management Stockholder to acquire such Share; or

(B) in either case following the Agreement Termination Date, the Management Stockholder shall be obligated to pay to the Company an amount equal to the amount which, as a result of such Management Stockholder’s exercise of Options at any time following, or within one year prior to, the date of termination of his or her Employment, such Management Stockholder was required to recognize as income for U.S. federal income tax purposes (or would have been required to recognize as income if the Management Stockholder was subject to U.S. federal income taxes).

(iv) The Company (or its designated assignee) shall exercise the call rights described in this Section 3(b) by delivering to the Management Stockholder or Transferee, as applicable, a written notice specifying its intent to purchase Shares held by the Management Stockholder or Transferee (the “Call Notice”) and the number of Shares to be purchased. The Company’s call right shall be deemed exercised as of the date on which the Company delivers such Call Notice to the Management Stockholder or Transferee. Such purchase and sale shall occur on such date as the Company (or its designated assignee) shall specify, which date shall be no later than forty-five (45) days after the end of the fiscal quarter in which the Call Notice is delivered. The Company will use commercially reasonable efforts to make the payment for the Shares in cash on the date of such purchase and sale; provided that, despite using such efforts, if such payment will result in the violation of the terms or provisions of, or result in a default or event of default under, any guarantee, financing or security agreement or document entered into by the Company or any of its Affiliates and in effect on such date (hereinafter a “Financing Agreement”), the Company may delay any such payment for no more than two (2) years. In the event the payment of the purchase price is delayed as a result of a restriction imposed by a Financing Agreement as provided above, such payment shall be made without the application of further conditions or impediments as soon as practicable after the payment of such purchase price would no longer result in the violation of the terms or provisions of, or result in a default or event of default under, any Financing Agreement, and such payment shall equal the amount that would have been paid to the Management Stockholder or Transferee if no delay had occurred plus interest for the period from the date on which the purchase price would have been paid but for the delay in payment provided herein to the date on which such payment is made (the “Delay Period”), calculated at an annual rate equal to the average annual prime rate charged during the Delay Period by a nationally recognized bank designated by the Board plus two (2) percentage points. In the event that the Company is not able to make payment within two (2) years after the date specified in the Call Notice, the Company will, upon the written request of the Management Stockholder or Transferee, cancel the Call Notice and return to the Management Stockholder or Transferee the Shares subject to the Call Notice (as adjusted to take into account any corporate transactions during the intervening period) in exchange for cancellation of the debt and any interest payments that would otherwise have been payable thereon.

(v) In the event that the Company exercises its call right to purchase Shares from the Management Stockholder under Section 3(b)(i) or Section 3(b)(iii) and, following the date that the Company pays the Management Stockholder the applicable purchase price for such Shares, the Management Stockholder violates any of the restrictive covenants set forth in the Plan or in any equity award grant agreement under the Plan, the Management Stockholder or the Management Stockholder’s Transferee shall pay to the Company, within ten (10) business days following the date of such violation, an amount equal to (A) the amount the Company paid the Management Stockholder or Transferee to purchase such Shares less (B) the amount the

8

Company would have been required to pay the Management Stockholder or Transferee for such Shares if the Company had purchased the Shares pursuant to Section 3(b)(ii)(A).

(c) Put Right. (i) In the event that, prior to the Agreement Termination Date, the Management Stockholder’s Employment with the Company terminates due to the Management Stockholder’s death or Disability, such Management Stockholder or her or his Transferee (as applicable) shall have the right, during the 180-day period following the later to occur of (x) such termination of Employment and (y) the date on which the Management Stockholder or Transferee has held the Shares most recently acquired to be sold pursuant to this Section 3(c)(i) for at least six (6) months, to sell to the Company (or its designated assignee), and upon the exercise of such right the Company (or its designated assignee) shall purchase from the Management Stockholder or Transferee, all or any portion of the Shares held by the Management Stockholder or Transferee as of the date on which such right is exercised at a per Share price equal to the Fair Market Value of a Share of Common Stock determined as of the date such right is exercised. The Management Stockholder or Transferee shall exercise such right by delivering to the Company a written notice (the “Put Notice”) specifying his or her intent to sell Shares held by the Management Stockholder or Transferee and the number of Shares to be sold. The Management Stockholder’s or Transferee’s put right shall be deemed exercised as of the date on which the Management Stockholder or Transferee delivers such Put Notice to the Company. Such purchase and sale shall occur on such date as the Company (or its designated assignee) shall specify, which date shall be no later than forty-five (45) days after the end of the fiscal quarter in which the Put Notice is delivered. The Company will use commercially reasonable efforts to make the payment for the Shares in cash on the date of such purchase and sale; provided that, despite using such efforts, if such payment will result in the violation of the terms or provisions of, or result in a default or event of default under, any Financing Agreement, the Company may delay any such payment until such restriction lapses as provided below. In the event the payment of the purchase price is delayed as a result of a restriction imposed by a Financing Agreement as provided above, the Company shall notify the Management Stockholder or Transferee as soon as practicable of the need for such a delay (the “Delay Notice”), and shall permit the Management Stockholder or Transferee, within ten (10) days of the delivery of the Delay Notice, to rescind the Put Notice. If the Management Stockholder or Transferee does not rescind the Put Notice as provided in the preceding sentence, the Put Notice shall remain outstanding and any payment in respect thereof shall be made without the application of further conditions or impediments as soon as practicable after the payment of such purchase price would no longer result in the violation of the terms or provisions of, or result in a default or event of default under, any Financing Agreement, and such payment shall equal the amount that would have been paid to the Management Stockholder or Transferee if no delay had occurred plus interest for the Delay Period, calculated at an annual rate equal to the average annual prime rate charged during the Delay Period by a nationally recognized bank designated by the Board plus two (2) percentage points

4. Certain Rights.

(a) Drag Along Rights. If one or more Majority Stockholder desires to (i) sell, prior to the Agreement Termination Date, forty percent (40%) or more of its direct or indirect pecuniary interest (as defined in Rule 16a-1 under the Exchange Act) in any Shares of Common Stock (including through the disposition of interests in LVB Acquisition Holding, LLC

9

(“LVB LLC”)), in a single transaction or a series of related transactions, to a good faith independent purchaser (a “Purchaser”) (other than any other Majority Stockholder, other investment partnership, limited liability company or other entity established for investment purposes and controlled by one or more of the members (other than passive investors) or the principals of the Majority Stockholder or any of their Affiliates and other than any Employees of the Majority Stockholder or their Affiliates, hereinafter referred to as a “Permitted Transferee”) upon such terms and conditions as agreed to with the Majority Stockholder, the Management Stockholder or Transferee agrees, at the request of the Majority Stockholder, to sell to such Purchaser a number of its Shares of Common Stock, not to exceed (a) the number of Shares of Common Stock held by such Management Stockholder or Transferee multiplied by (b) a fraction, the numerator of which is the aggregate number of Shares of Common Stock in which the Majority Stockholder has a pecuniary interest that such Majority Stockholder has proposed to be transferred, and the denominator of which is the aggregate number of Shares of Common Stock in which the Majority Stockholder has a pecuniary interest (or to vote such number of Shares in favor of any merger or other transaction which would effect a sale of such Shares) at the same price per share of Common Stock and pursuant to the same terms and conditions with respect to payment for the Shares as agreed to by the Majority Stockholder; provided that, except with respect to any liability incurred by such Management Stockholder or any Transferee individually, the Management Stockholders and any Transferees shall not be liable to a Purchaser for an amount greater than the proceeds from the sale. In such case, the Majority Stockholder shall give written notice of such sale to the Management Stockholder or Transferee at least fifteen (15) days prior to the consummation of such sale, setting forth (i) the consideration to be received by the holders of shares of Common Stock, (ii) the identity of the Purchaser, (iii) any other material terms and conditions of the proposed Transfer and (iv) the date of the proposed Transfer. The Company shall be responsible for the proportionate share of the costs of the proposed Transfer incurred by the Management Stockholders and any Transferees to the extent not paid or reimbursed by the proposed Purchaser. Notwithstanding the foregoing, the Management Stockholder shall not be required to agree to any additional non-compete or similar restrictions in connection with the sale.

(b) Tag Along Rights.

(i) Subject to paragraph (iv) of this Section 4(b), if one or more Majority Stockholder or its Permitted Transferee proposes to transfer, prior to the Agreement Termination Date, its direct or indirect pecuniary interest (as defined in Rule 16a-1 under the Exchange Act) in any Shares of Common Stock (including through the disposition of interests in LVB LLC) to a Purchaser (other than a Permitted Transferee), other than a transfer through an Initial Public Offering or any secondary registered equity offering, then the Majority Stockholder or his or her Permitted Transferee (hereinafter referred to as a “Selling Stockholder”) shall give written notice of such proposed transfer to the Management Stockholder or Transferee (the “Selling Stockholder’s Notice”) at least thirty (30) days prior to the consummation of such proposed transfer, and shall provide notice to all other stockholders of the Company to whom the Majority Stockholder has granted similar “tag-along” rights (such stockholders together with the Management Stockholder or Transferee, referred to herein as the “Other Stockholders”) setting forth the proposed material terms and conditions of such Transfer (including price per Share).

10

(ii) The Management Stockholder or Transferee shall have the right to elect, by delivery of written notice to the Majority Stockholder within twenty (20) days from delivery of the Selling Stockholder’s Notice, to sell to the proposed Transferee a number of its Shares of Common Stock, not to exceed the product of (A) the total number of Shares, including any shares of Common Stock underlying vested Options (or options that would become vested in connection with the proposed transfer), owned by the Management Stockholder or Transferee and (B) a fraction, the numerator of which is the aggregate number of Shares of Common Stock in which the Majority Stockholder has a pecuniary interest that such Majority Stockholder has proposed to be transferred, and the denominator of which is the aggregate number of Shares of Common Stock in which the Majority Stockholder has a pecuniary interest (the Management Stockholder’s or Transferee’s “Pro Rata Amount”), on the same terms and conditions (including price per share of Common Stock) as agreed to by the Selling Stockholder. In the event that the Transferee does not wish to acquire all of the Shares offered by the Management Stockholder or Transferee, the number of Shares of Common Stock to be purchased by such Transferee shall be allocated pro rata among the Majority Stockholders and the Other Stockholders in accordance with the number of Shares of Common Stock and Shares underlying vested Options that each such stockholder elected to transfer to the Transferee.

(iii) In order to be entitled to exercise its rights pursuant to this Section 4(b), the Management Stockholder or Transferee must agree to make to the proposed Purchaser representations, warranties, covenants, indemnities and agreements comparable to those made by the Selling Stockholder in connection with the proposed transfer and agree to the same conditions to the proposed transfer as the Selling Stockholder agrees, it being understood that all such representation, warranties, covenants, indemnities and agreements shall be made by the Selling Stockholder, the Management Stockholder or Transferee and any Other Stockholder exercising similar tag-along rights severally and not jointly provided that the Selling Stockholder shall not be required to agree to any additional non-compete or similar restrictions in connection with the sale. The Selling Stockholder, the Management Stockholder or Transferee and any Other Stockholder who exercises similar tag-along rights each shall be responsible for its proportionate share of the costs of the proposed Transfer to the extent not paid or reimbursed by the proposed Purchaser or the Company.

(iv) In connection with the exercise of its tag-along rights under paragraph (ii) of this Section 4(b), or its transfer rights under Section 3(a)(iii), if the Management Stockholder or Transferee desires to exercise vested Options to acquire up to the number of Shares the Management Stockholder or Transferee is permitted to sell pursuant to the exercise of its tag-along rights under paragraph (ii) of this Section 4(b), or its transfer rights under Section 3(a)(iii), the Company will permit the Management Stockholder or Transferee, to the extent permitted under the Plan, to exercise any such vested Options through net-physical settlement (net of the applicable exercise price and applicable withholding taxes) if the Company’s independent auditors determine that net-physical settlement of any such Options would not produce less-favorable accounting consequences for the Company than if the Management Stockholder or Transferee paid the exercise price for any such vested Options in cash.

(v) Notwithstanding anything to the contrary contained herein, the provisions of this Section 4(b) shall not apply during the period from the Effective Time through the first anniversary of the Effective Time to any sale or transfer by a Majority Stockholder of its

11

pecuniary interest in any Shares of Common Stock (including through the disposition of interests in LVB LLC) for a price that is equal to or less than the Fair Market Value of such Share of Common Stock as of the Effective Time unless and until the Majority Stockholder, after giving effect to the proposed sale or transfer, shall have sold or transferred in the aggregate (other than to Permitted Transferees or to officers, employees or directors of, or consultants to, the Company or any of its subsidiaries) its pecuniary interest in Shares of Common Stock representing 15.0% or more of the Shares of Common Stock in which the Majority Stockholder collectively had a pecuniary interest as of the Effective Time.

(c) Permitted Transferees. Any Permitted Transferee to which a Majority Stockholder’s pecuniary interest in any Shares of Common Stock (including interests in LVB LLC) is Transferred shall agree to execute this Agreement as a condition to such Transfer.

5. Registration. The Company shall have no obligation to register the Shares.

6. Termination. This Agreement shall terminate with respect to the Common Stock immediately following the later to occur of (a) an Initial Public Offering or (b) the fifth anniversary of the Effective Time (the “Agreement Termination Date”) except that (i) if an Initial Public Offering has occurred on or prior to the Agreement Termination Date, and the Lockup Period has not expired as of the Agreement Termination Date, the requirements of Sections 3(a)(ii) and 5(b) hereof shall survive the termination of this Agreement, (ii) the provisions of Section 3(b)(ii)(B) hereof shall survive the termination of this Agreement and (iii) the requirements contained in Section 2 hereof shall survive the termination of this Agreement, provided that a Management Stockholder or his or her Transferee may sell Shares pursuant to Rule 144 of the Securities Act if such Management Stockholder or Transferee meets and complies with all of the applicable requirements thereof.

7. Acknowledgements of the Management Stockholder, LVB Acquisition Holding, LLC and the Company.

(a) The Management Stockholder acknowledges that the Majority Stockholder will own interests in LVB LLC and will own its shares of Common Stock through LVB LLC, and that the Majority Stockholder will have governance and other rights with respect to the Company that are different from (and may be greater than) the rights to which the Management Stockholder is entitled.

(b) The Company and LVB LLC hereby acknowledge that the Management Stockholders shall not be economically disadvantaged with respect to the Shares or Options solely by reason of holding shares or options to purchase shares of the Company’s Common Stock instead of membership interests or options to purchase membership interests in LVB LLC. In the event there is a corporate transaction affecting the membership interests of LVB LLC or any dividend or distribution made to holders of the membership interests in LVB LLC in respect of such interests, the Company and LVB LLC shall take commercially reasonable steps to assure that appropriate adjustments and/or dividends or distributions are made to or in respect of the Shares such that the Management Stockholders will be in the same economic position in which they would have been had they received membership interests in LVB LLC instead of the

12

Shares; provided that this Section 7 shall not be construed to entitle any Management Stockholder to any membership or other interests in LVB LLC. For purposes of this Agreement, no Management Stockholder shall be deemed to be economically disadvantaged from a tax perspective by reason of his holding Options or Shares as opposed to membership interests in a limited liability company or partnership interests in a partnership.

8. Distributions With Respect To Shares. As used herein, the term “Shares” includes securities of any kind whatsoever distributed with respect to the Company’s Common Stock acquired by the Management Stockholder or his or her or her Transferee (whether pursuant to the Plan, the letter agreement dated on or about August 27, 2007 between the Company and such Management Stockholder or otherwise) or any such securities resulting from a stock split or consolidation involving such Common Stock.

9. Amendment; Assignment. This Agreement may be amended, superseded, canceled, renewed or extended, and the terms hereof may be waived, only by a written instrument signed by authorized representatives of the parties or, in the case of a waiver, by an authorized representative of the party waiving compliance. No such written instrument shall be effective unless it expressly recites that it is intended to amend, supersede, cancel, renew or extend this Agreement or to waive compliance with one or more of the terms hereof, as the case may be. Except for the Management Stockholder’s right to assign his or her rights under Section 4(a) or the Company’s right to assign its rights under Section 4(b), no party to this Agreement may assign any of its rights or obligations under this Agreement without the prior written consent of the other parties hereto.

10. Notices. Each notice and other communication hereunder shall be in writing and shall be given and shall be deemed to have been duly given on the date it is delivered in person, on the next business day if delivered by overnight mail or other reputable overnight courier, or the third business day if sent by registered mail, return receipt requested, to the parties as follows:

The Rollover Shares so contributed will be canceled and retired without any conversion thereof or payment or distribution thereon, as set forth in Section 4.1 of the Merger Agreement. In exchange for the Rollover Shares and your Cash Contribution, you will receive a number of Shares equal to the amount of your investment as indicated on the Acceptance Form attached hereto, divided by $10, which is equal to the price per Share to be paid by the Majority Holders (as defined below) for their Shares. You will be the holder of record of the Shares in which you invest as of the Closing, whether or not Newco issues physical certificates to you for such Shares. This offer is conditioned upon the occurrence of the Closing. If the Closing does not occur, this Agreement will be canceled and will be of no force and effect.

3. Form of Consideration. If you choose to invest in the Shares, (i) you must commit to invest a minimum of $50,000 and (ii) you must then satisfy your investment (a) with respect to any Rollover Shares you invest, by contributing all or a portion of Biomet shares of common stock that you hold as a capital asset (e.g., shares you acquired on the market or shares you acquired by exercising stock options), if any, and/or (b) by making your Cash Contribution, if any. Your Cash Contribution must be received by wire transfer by no later than 5:00 p.m. (Five p.m., Eastern Daylight Savings Time) on Monday, September 17, 2007 (wire information will be provided to you). Delivery of any Rollover Shares will occur as follows: (x) with respect to Rollover Shares, if any, for which physical certificates were delivered to you, by delivering to LVB the physical certificates that were so issued; and (y) with respect to Rollover Shares you hold through a brokerage account, by having the brokerage firm by which such Rollover Shares are held transfer those Rollover Shares to an account established in Newco’s name (the “Newco Account”) (transfer instructions will be provided to you). Delivery of physical certificates for Rollover Shares (if any) must be made via Federal Express or United Parcel Service (UPS) to LVB Acquisition, Inc., c/o Bradley J. Tandy, Senior Vice President, General Counsel & Secretary, Biomet, Inc., 56 East Bell Drive, Warsaw, IN 46582, U.S.A., by no later than 5:00 p.m. (Five p.m., Eastern Daylight Savings Time) on Monday, September 17, 2007. Rollover Shares that are being electronically transferred (if any) must be credited to the Newco Account by no later than 5:00 p.m. (Five p.m., Eastern Daylight Savings Time) on Monday, September 17, 2007, which means that you should instruct your broker to initiate the transfer no later than 4:00 pm. on Monday, September 17, 2007. The Rollover Shares should not be transferred prior to Monday, September 17, 2007.

4. Acceptance and Closing; Conditions. You may accept this offer and the terms of this Agreement by completing and returning the Acceptance Form attached hereto, in which case the closing of your acquisition of the Shares will occur immediately after the Closing. This offer is conditioned upon the occurrence of the Closing. If the Closing does not occur on or before October 31, 2007 (the “Closing Deadline”), this Agreement will be canceled and you will have no rights with respect hereto and any Rollover Shares that you have transferred or cash payment that you have made pursuant to Section 3 will be returned to you within 3 business days of the Closing Deadline; provided, that if Newco determines on or before the Closing Deadline and in good faith that the Closing is likely to occur on or before November 30, 2007, the Closing Deadline shall automatically be extended to November 30, 2007.

5. Limitation. Newco, in its discretion, may limit the number of Shares that you may purchase, and therefore may choose not to accept the full amount of your investment election. Rollover Shares not accepted pursuant to the preceding sentence will be treated in accordance with the provisions of the Merger Agreement.

6. Vesting. Your Shares when issued will be fully vested.

7. Stockholders’ Agreement. By completing and returning the Acceptance Form below, you agree to become a party to the Management Stockholders’ Agreement, as may be amended from time to time in accordance with its terms (the “Stockholders’ Agreement”) and you will be subject to the terms and conditions thereof with respect to your Shares. The Stockholders’ Agreement will be provided to you a reasonable time prior to September 14, 2007. Newco agrees that it will, and that it will cause the Majority Holders (as defined below) to, also become a party to the Stockholders’ Agreement.

8. Tax Reporting. It is intended that your contribution of the Rollover Shares, if any, shall be treated as a tax-free transfer under Section 351 of the Internal Revenue Code of 1986, as amended (the “Code”), which transfer encompasses the original transfer of cash by LVB Acquisition Holding, LLC to LVB Acquisition, Inc. (formerly LVB Acquisition, LLC) in connection with the transactions contemplated by the Merger Agreement and the transfers by you and other members of management of Cash Contributions (if any) and Rollover Shares (if any), and Newco and Biomet will report, and will procure that their respective affiliates report, consistently with such treatment.

All discussions of U.S. federal tax considerations in this document have been written to support the marketing of the Shares. Such discussions were not intended or written to be used, and cannot be used by any taxpayer, for the purpose of avoiding U.S. federal tax penalties. You should consult your own tax advisers in determining the tax consequences of the rollover and of holding the Shares, including the application to your particular situation of the U.S. federal tax considerations discussed herein, as well as the application of state, local, foreign, or other tax laws.

9. Representations; Acknowledgements. By signing below and completing and returning the Acceptance Form, you hereby represent and warrant to Newco and Biomet that:

(iii) the Acceptance Form has been duly and validly executed and delivered by you and constitutes your legal, valid and binding obligation, enforceable against you in accordance with its terms, except to the extent that such validly binding effect and enforceability may be limited by applicable bankruptcy, reorganization, insolvency, moratorium and other laws relating to or affecting creditors’ rights generally;

(iv) the Shares are being acquired for your own account, for investment purposes only and not with a view to or in connection with any distribution, reoffer, resale, public offering or other disposition thereof not in compliance with the Securities Act of 1933, as amended (the “Securities Act”), as may be amended from time to time, or any applicable United States federal or state securities laws or regulations;

(v) you possess expertise, knowledge, and sophistication in financial and business matters generally, and in the type of transaction in which Biomet and Newco propose to engage in particular;
