ITEM 1.01. ENTRY INTO A MATERIAL DEFINITVE AGREEMENT. EMPLOYMENT AGREEMENT WITH JOHN B. HENNEMAN, III On December 19, 2005, Integra LifeSciences Holdings Corporation (the "Company") entered into an Amended and Restated Employment Agreement with John B. Henneman, III, the Company's Executive Vice President and Chief Administrative Officer. The following is a summary of the material terms of the agreement. Term The employment agreement extends Mr. Henneman's term of employment with the Company through January 3, 2009, with an automatic extension of the term of employment for consecutive one year periods unless the Company or Mr. Henneman provides notice that it or he elects not to extend the term. Compensation and Benefits The employment agreement provides that Mr. Henneman's base salary will increase to $420,000, effective January 1, 2006. In addition, Mr. Henneman will have a target bonus opportunity of 40% of his base salary, based upon the satisfaction of certain performance objectives as determined by the Compensation Committee of the Board of Directors of the Company, in its sole discretion. Mr. Henneman is also eligible to participate in the Company's employee benefit plans, stock-based plans and any other plans and benefits covering executives of the Company. Equity Grant Mr. Henneman's employment agreement provides for an award to Mr. Henneman of 100,000 shares of the Company's common stock, subject to restrictions and forfeiture, under the Company's 2003 Equity Incentive Plan. The award will be made on January 3, 2006, and the award agreement will provide that shares of common stock will be issued to Mr. Henneman on January 3, 2009 if the Company sales in 2006, 2007 or 2008 are greater than sales in 2005. The shares will be issued earlier if the Company experiences a change in control or Mr. Henneman's employment is terminated without cause, for good reason, disability or death. The employment agreement also provides that all equity compensation grants made to Mr. Henneman by the Compensation Committee will fully vest upon the occurrence of a change in control of the Company or if Mr. Henneman's employment with the Company is terminated without cause, for good reason, disability or death. In addition, if the term of the employment agreement is not renewed, then a portion of Mr. Henneman's outstanding shares of restricted stock will be deemed to have vested as of the last day of his employment with the Company based on the number of days that he worked for the Company after the grant of restricted stock and the total number of days in the restriction period set forth in the restricted stock grant. Severance Payments If Mr. Henneman's employment with the Company is terminated by the Company for a reason other than death, disability or cause or Mr. Henneman terminates employment with the Company for good reason or because the Company does not extend the term of the employment agreement pursuant to the automatic renewal provision, the Company will pay to him a lump sum cash severance amount equal to the sum of his annual base salary as of his last day of active employment and his target bonus. In addition, the Company will continue to maintain and provide to Mr. Henneman continued participation in all group insurance, life insurance, health and accident, disability and other employee benefit plans of the Company in which he would have been entitled to participate had his employment not terminated, at no cost, for a period ending on the earlier to occur of (i) the first anniversary of his last day of employment, (ii) the date

he is employed on a full-time basis by another employer, or (iii) his death, provided the continued participation in such plan is not prohibited by the terms of the plan or for legal reasons. Mr. Henneman's employment agreement provides that, instead of the foregoing severance benefits, if within 12 months of a change in control of the Company, his employment with the Company is terminated by the Company for a reason other than death, disability or cause or he terminates employment with the Company for good reason or because the Company does not extend the term of the employment agreement pursuant to the automatic renewal provision, the Company will pay to him a lump sum cash payment equal to 2.99 times the sum of his annual base salary as of his last day of active employment and target bonus. In addition, the Company will continue to maintain and provide to Mr. Henneman continued participation in all group insurance, life insurance, health and accident, disability and other employee benefit plans of the Company in which he would have been entitled to participate in had his employment not terminated, at no cost, for a period ending on the earlier to occur of (i) the fifth anniversary of the employment agreement or (ii) his death, provided the continued participation in such plan is not prohibited by the terms of the plan or for legal reasons. All reasonable fees and expenses incurred by Mr. Henneman as a result of his termination of employment will be paid by the Company. The above severance benefits are conditioned on Mr. Henneman and the Company executing mutual releases. If any payment, coverage or benefit provided to Mr. Henneman is subject to the excise tax under Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), he will receive a "gross-up" payment so he would be in the same net after-tax position he would have been in had Sections 280G and 4999 not been part of the Code. Death of Executive If Mr. Henneman dies during the term of his employment agreement, the Company will pay his spouse death benefits equal to a lump sum payment equal to Mr. Henneman's base salary, and his spouse and dependents will be eligible to continue to participate in the Company's health benefit plan for a period of one year from the date of Mr. Henneman's death, at no cost, provided such participation is not prohibited by the terms of the plan or for legal reasons. Restrictive Covenants Mr. Henneman's employment agreement provides that during the term of this agreement, and for the one year period after Mr. Henneman's termination of employment with the Company, Mr. Henneman will be subject to certain covenants not to compete against the Company.
