GUARANTY

SECTION 2.01. Guaranty. Each Guarantor irrevocably, absolutely and unconditionally guaranties, jointly with the other Guarantors and severally, the due and punctual payment of the Obligations, in each case, whether such Obligations are now existing or hereafter incurred under, arising out of any Loan Document whether at stated maturity or earlier, by reason of acceleration, mandatory prepayment or otherwise in accordance herewith or with any other Loan Documents. Each of the Guarantors further agrees that the Obligations may be extended, increased or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guaranty notwithstanding any extension, increase or renewal, in whole or in part, of any Obligation. Each of the Guarantors waives presentment to, demand of payment from and protest to any Guaranty Party of any of the Obligations, and also waives notice of acceptance of its guaranty and notice of protest for nonpayment.

SECTION 2.02. Guaranty of Payment. Each of the Guarantors further agrees that its guaranty hereunder constitutes a guaranty of payment when due and not of collection, and waives any right to require that any resort be had by the Administrative Agent or any other Secured Party to any security held for the payment of the Obligations, or to any balance of any deposit account or credit on the books of the Administrative Agent or any other Secured Party in favor of the Borrower or any other Person.

SECTION 2.03. No Limitations. (a) Except for termination of a Guarantor’s obligations hereunder as expressly provided in Section 4.11, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Obligations, or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor hereunder shall not be discharged or impaired or otherwise affected by (i) the failure of the Administrative Agent or any other Secured Party to assert any claim or demand or to enforce any right or remedy under the provisions of any Loan Document or otherwise; (ii) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, any Loan Document or any other agreement, including with respect to any other Guarantor under this Agreement; (iii) the release of any security held by the Administrative Agent or any other Secured Party for the Obligations; (iv) any default, failure or delay, willful or otherwise, in the performance of the Obligations; or (v) any other act or omission that may or might in any manner or to any extent vary the risk of any Guarantor or otherwise operate as a discharge of any Guarantor as a matter of law or equity (other than the indefeasible payment in full in cash of all the Obligations). Each Guarantor expressly authorizes the Secured Parties to take and hold security for the Obligations, to exchange, waive or release any or all such security (with or without consideration), to enforce or apply such security and direct the order and manner of any sale thereof in their sole discretion or to release or substitute any one or more other guarantors or obligors upon or in respect of the Obligations, all in accordance with the Security Agreement and other Loan Documents and all without affecting the obligations of any Guarantor hereunder.

(b) To the fullest extent permitted by applicable law, each Guarantor waives any defense based on or arising out of any defense of any Guaranty Party or the unenforceability of the Obligations, or any part thereof from any cause, or the cessation from any cause of the liability of any Guaranty Party, other than the indefeasible payment in full in cash of all the Obligations. The Administrative Agent and the other Secured Parties may, in accordance with the terms of the Collateral Documents and at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept an assignment of any such security in lieu of foreclosure, compromise or adjust any part of the Obligations, make any other accommodation with any Guaranty Party or exercise any other right or remedy available to them against any Guaranty Party, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Obligations have been fully and indefeasibly paid in full in cash. To the fullest extent permitted by applicable law, each Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against any Guaranty Party, as the case may be, or any security.

SECTION 2.04. Reinstatement. Each of the Guarantors agrees that its guaranty hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation, is rescinded, invalidated or must otherwise be restored by the Administrative Agent or any other Secured Party upon the bankruptcy or reorganization of any Guaranty Party or otherwise.

SECTION 2.05. Agreement To Pay; Subrogation. In furtherance of the foregoing and not in limitation of any other right that the Administrative Agent or any other Secured Party has at law or in equity against any Guarantor by virtue hereof, upon the failure of any Guaranty Party to pay any Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Guarantor hereby promises to and will forthwith pay, or cause to be paid, to the Administrative Agent for distribution to the Secured Parties in cash the amount of such unpaid Obligation. Upon payment by any Guarantor of any sums to the Administrative Agent as provided above, all rights of such Guarantor against any Guaranty Party arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all respects be subject to Article III herein.

SECTION 2.06. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of each Guaranty Party’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Obligations, and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Administrative Agent or the other Secured Parties will have any duty to advise such Guarantor of information known to it or any of them regarding such circumstances or risks.

ARTICLE III

INDEMNITY, SUBROGATION AND SUBORDINATION

SECTION 3.01. Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation as the Guarantors may have under applicable law (but subject to Section 3.03), the Borrower agrees that in the event a payment of an obligation shall be made by any Guarantor under this Agreement, the Borrower shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the Person to whom such payment shall have been made to the extent of such payment.

SECTION 3.02. Contribution and Subrogation. Each Guarantor (a “Contributing Party”) agrees (subject to Section 3.03) that, in the event a payment shall be made by any other Guarantor hereunder in respect of any Obligation and such other Guarantor (the “Claiming Party”) shall not have been fully indemnified by the Borrower as provided in Section 3.01, the Contributing Party shall indemnify the Claiming Party in an amount equal to the amount of such payment, in each case multiplied by a fraction of which the numerator shall be the net worth of the Contributing Party on the date hereof and the denominator shall be the aggregate net worth of all the Contributing Parties together with the net worth of the Claiming Party on the date hereof (or, in the case of any Guarantor becoming a party hereto pursuant to Section 4.12, the date of the Guaranty Supplement hereto executed and delivered by such Guarantor). Any Contributing Party making any payment to a Claiming Party pursuant to this Section 3.02 shall be subrogated to the rights of such Claiming Party to the extent of such payment. Each Guarantor recognizes and acknowledges that the rights to contribution arising hereunder shall constitute an asset in favor of the party entitled to such contribution. In this connection, each Guarantor has the right to waive, to the fullest extent permitted by applicable law, its contribution right against any other Guarantor to the extent that after giving effect to such waiver such Guarantor would remain solvent, in the determination of the Lenders.

SECTION 3.03. Subordination. (a) Notwithstanding any provision of this Agreement to the contrary, all rights of the Guarantors under Sections 3.01 and 3.02 and all other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full in cash of the Obligations; provided that if any amount shall be paid to such Guarantor on account of such subrogation rights at any time prior to the irrevocable payment in full of the Obligations, such amount shall be held in trust for the benefit of the Secured Parties and shall forthwith be paid to the Administrative Agent to be credited and applied against the Obligations, whether matured or unmatured, in connection with Section 8.03 of the Credit Agreement. No failure on the part of the Borrower or any Guarantor to make the payments required by Sections 3.01 and 3.02 (or any other payments required under applicable law or otherwise) shall in any respect limit the obligations and liabilities of any Guarantor with respect to its obligations hereunder, and each Guarantor shall remain liable for the full amount of the obligations of such Guarantor hereunder.

ARTICLE IV

MISCELLANEOUS

SECTION 4.01. Notices. All communications and notices hereunder shall (except as otherwise expressly permitted herein) be in writing and given as provided in Section 10.02 of the Credit Agreement. All communications and notices hereunder to any Guarantor shall be given to it in care of the Borrower as provided in Section 10.02 of the Credit Agreement.

SECTION 4.02. Waivers; Amendment. (a) No failure or delay by the Administrative Agent, any L/C Issuer or any other Secured Party in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the L/C Issuers and the other Secured Parties hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Guaranty Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 4.02, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or any L/C Issuer may have had notice or knowledge of such Default at the time. No notice or demand on any Guaranty Party in any case shall entitle any Guaranty Party to any other or further notice or demand in similar or other circumstances.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Guaranty Party or Guaranty Parties with respect to which such waiver, amendment or modification is to apply, subject to any consent required in accordance with Section 10.01 of the Credit Agreement.

SECTION 4.03. Administrative Agent’s Fees and Expenses, Indemnification. (a) The parties hereto agree that the Administrative Agent shall be entitled to reimbursement of its expenses incurred hereunder as provided in Section 10.04 of the Credit Agreement.

(b) Without limitation of its indemnification obligations under the other Loan Documents, the Borrower agrees to indemnify the Administrative Agent and the other Indemnitees (as defined in Section 10.05 of the Credit Agreement) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of, the execution, delivery or performance of this Agreement or any claim, litigation, investigation or proceeding relating to any of the foregoing agreements or instruments contemplated hereby, whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee or of any Affiliate, director, officer, employee or agent of such Indemnitee.

(c) Any such amounts payable as provided hereunder shall be additional Obligations guaranteed hereby and secured by the other Collateral Documents. The provisions of this Section 4.03 shall remain operative and in full force and effect regardless of the termination of this Agreement or any other Loan Document, the consummation of the transactions contemplated hereby, the repayment of any of the Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Administrative Agent or any other Secured Party. All amounts due under this Section 4.03 shall be payable within 20 Business Days of written demand therefor.

SECTION 4.04. Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof, and shall continue in full force and effect as long as any Loan or any other Obligation shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

SECTION 4.05. Counterparts; Effectiveness; Successors and Assigns; Several Agreement. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by telecopier or electronic transmission of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement. The Administrative Agent may also require that any such documents and signatures delivered by telecopier or electronic transmission be confirmed by a manually signed original thereof; provided that the failure to request or deliver the same shall not limit the effectiveness of any document or signature delivered by telecopier or electronic transmission. This Agreement shall become effective as to any Guaranty Party when a counterpart hereof executed on behalf of such Guaranty Party shall have been delivered to the Administrative Agent and a counterpart hereof shall have been executed on behalf of the Administrative Agent, and thereafter shall be binding upon such Guaranty Party and the Administrative Agent and their respective successors and assigns permitted thereby, and shall inure to the benefit of such Guaranty Party, the Administrative Agent and the other Secured Parties and their respective successors and assigns permitted thereby, except that no Guaranty Party shall have the right to assign or transfer its rights or obligations hereunder or any interest herein (and any such assignment or transfer shall be void) except as expressly contemplated by this Agreement or the other Loan Documents. This Agreement shall be construed as a separate agreement with respect to each Guaranty Party and may be amended, modified, supplemented, waived or released with respect to any Guaranty Party without the approval of any other Guaranty Party and without affecting the obligations of any other Guaranty Party hereunder.

SECTION 4.06. Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

SECTION 4.07. Right of Set-Off. In addition to any rights and remedies of the Lenders provided by Law, upon the occurrence and during the continuance of any Event of Default, each Lender and its Affiliates and each L/C Issuer and its Affiliates is authorized at any time and from time to time, without prior notice to any Guarantor, any such notice being waived by each Guarantor (on its own behalf and on behalf of its Subsidiaries) to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other Indebtedness at any time owing by, such Lender and its Affiliates or such L/C Issuer and its Affiliates, as the case may be, to or for the credit or the account of the respective Loan Parties and their Subsidiaries against any and all Obligations owing to such Lender and its Affiliates or such L/C Issuer and its Affiliates hereunder or under any other Loan Document, now or hereafter existing, irrespective of whether or not such L/C Issuer or such Lender or Affiliate shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or Indebtedness. Notwithstanding anything to the contrary contained herein, no Lender or its Affiliates and no L/C Issuer or its Affiliates shall have a right to set off and apply any deposits held or other Indebtedness owing by such Lender or its Affiliates or such L/C Issuer or its Affiliates, as the case may be, to or for the credit or the account of any Subsidiary of a Loan Party that is not a “United States person” within the meaning of Section 7701(a)(30) of the Code unless such Subsidiary is not a direct or indirect subsidiary of Holdings. Each Lender and L/C Issuer agrees promptly to notify the Borrower and the Administrative Agent after any such set off and application made by such Lender or L/C Issuer, as the case may be; provided, that the failure to give such notice shall not affect the validity of such setoff and application. The rights of the Administrative Agent, each Lender and each L/C Issuer under this Section 4.07 are in addition to other rights and remedies (including other rights of setoff) that the Administrative Agent, such Lender and such L/C Issuer may have.

SECTION 4.08. Governing Law; Jurisdiction; Venue; Waiver of Jury Trial; Consent to Service of Process. (a) The terms of Sections 10.15 and 10.16 of the Credit Agreement with respect to governing law, submission of jurisdiction, venue and waive of trial are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms.

(b) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 4.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 4.09. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 4.10. Guaranty Absolute. To the fullest extent permitted by applicable law, all rights of the Administrative Agent hereunder and all obligations of each Guarantor hereunder shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Credit Agreement, any other Loan Document, any agreement with respect to any of the Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Credit Agreement, any other Loan Document, or any other agreement or instrument, (c) any exchange, release or non-perfection of any Lien on other collateral, or any release or amendment or waiver of or consent under or departure from any guaranty securing or guaranteeing all or any of the Obligations or (d) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Guarantor in respect of the Obligations or this Agreement.

SECTION 4.11. Termination or Release. (a) This Agreement and the Guaranties made herein shall terminate with respect to all Obligations when all the outstanding Obligations (other than (x) obligations under Secured Hedge Agreements not yet due and payable, (y) Cash Management Obligations not yet due and payable and (z) contingent indemnification obligations not yet accrued and payable) have been indefeasibly paid in full and the Lenders have no further commitment to lend under the Credit Agreement, the Outstanding Amount of L/C Obligations has been reduced to zero and the L/C Issuers have no further obligations to issue Letters of Credit under the Credit Agreement.

(b) A Guarantor shall automatically be released from its obligations hereunder as provided in Section 9.11 of the Credit Agreement.

(c) In connection with any termination or release pursuant to paragraph (a) or (b) of this Section 4.11, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantor’s expense, all documents that such Guarantor shall reasonably request to evidence such termination or release, in each case in accordance with the terms of Section 9.11 of the Credit Agreement. Any execution and delivery of documents pursuant to this Section 4.11 shall be without recourse to or warranty by the Administrative Agent.

(d) At any time that the Borrower desires that the Administrative Agent take any of the actions described in immediately preceding paragraph (c), it shall, upon request of the Administrative Agent, deliver to the Administrative Agent an officer’s certificate certifying that the release of the respective Guarantor is permitted pursuant to paragraph (a) or (b). The Administrative Agent shall have no liability whatsoever to any Guarantor as a result of any release of any Guarantor by it as permitted (or which the Administrative Agent in good faith believes to be permitted) by this Section 4.11.

(e) Notwithstanding anything to the contrary set forth in this Agreement, each Cash Management Bank and each Hedge Bank, by the acceptance of the benefits under this Agreement hereby acknowledge and agree that (i) the obligations of the Borrower or any Subsidiary under any Secured Hedge Agreement and the Cash Management Obligations shall be guaranteed pursuant to this Agreement only to the extent that, and for so long, the other Obligations are so guaranteed and (ii) any release of a Guarantor effected in the manner permitted by this Agreement shall not require the consent of any Hedge Bank or Cash Management Bank.

SECTION 4.12. Additional Guarantors. Each Material Domestic Subsidiary of the Borrower that is required to enter in this Agreement as a Guarantor pursuant to Section 6.11 of the Credit Agreement shall execute and deliver a Guaranty Supplement and thereupon such Material Domestic Subsidiary shall become a Guarantor hereunder with the same force and effect as if originally named as a Guarantor herein. The execution and delivery of any such instrument shall not require the consent of any other Guaranty Party hereunder. The rights and obligations of each Guaranty Party hereunder shall remain in full force and effect notwithstanding the addition of any new Guaranty Party as a party to this Agreement.

SECTION 4.13. Limitation on Guaranteed Obligations. Each Guarantor and each Secured Party (by its acceptance of the benefits of this Agreement) hereby confirms that it is its intention that this Agreement not constitute a fraudulent transfer or conveyance for purposes of any Debtor Relief Laws (including the Bankruptcy Code, the Uniform Fraudulent Conveyance Act or any similar Federal or state law). To effectuate the foregoing intention, each Guarantor and each Secured Party (by its acceptance of the benefits of this Agreement) hereby irrevocably agrees that the Obligations owing by such Guarantor under this Agreement shall be limited to such amount as will, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Guarantor that are relevant under such Debtor Relief Laws and after giving effect to any rights to contribution and/or subrogation pursuant to any agreement providing for an equitable contribution and/or subrogation among such Guarantor and the other Guarantors, result in the Obligations of such Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance.

EXHIBIT I

SUPPLEMENT NO. dated as of [ ], to the Guaranty dated as of September 25, 2007 among LVB ACQUISITION, INC. (“Holdings”), certain Subsidiaries of BIOMET, INC. from time to time party thereto and BANK OF AMERICA, N.A., as Administrative Agent.

A. Reference is made to (i) the Credit Agreement dated as of September 25, 2007 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, Holdings, Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, and each lender from time to time party thereto (collectively, the “Lenders” and individually, a “Lender”), (ii) each Secured Hedge Agreement (as defined in the Credit Agreement) and (iii) the Cash Management Obligations (as defined in the Credit Agreement).

B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement.

C. The Guarantors have entered into the Guaranty in order to induce (x) the Lenders to make Loans and the L/C Issuers to issue Letters of Credit, (y) the Hedge Banks to enter into and/or maintain Secured Hedge Agreements and (z) the Cash Management Banks to provide Cash Management Services. Section 4.12 of the Guaranty provides that additional Material Domestic Subsidiaries of the Borrower may become Guarantors under the Guaranty by execution and delivery of an instrument in the form of this Supplement. The undersigned Material Domestic Subsidiary (the “New Subsidiary”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Guarantor under the Guaranty in order to induce (x) the Lenders to make additional Loans and the L/C Issuers to issue additional Letters of Credit, (y) the Hedge Banks to enter into and/or maintain Secured Hedge Agreements and (z) the Cash Management Banks to provide Cash Management Services and as consideration for (x) Loans previously made and Letters of Credit previously issued, (y) Secured Hedge Agreements previously entered into and/or maintained and (z) Cash Management Services previously provided.

Accordingly, the Administrative Agent and the New Subsidiary agree as follows:
