              o  Annualized base salaries for the Company's executive officers
                 were increased effective as of March 1, 2005, and are as
                 follows:

                                                           Base annual
                       Executive Officer                     salary
                    -----------------------             ----------------
                    Dr. Louis F. Centofanti             $        225,000
                    Richard T. Kelecy                            182,000
                    Larry McNamara                               185,000
                    Timothy P. Keegan                            180,000

              o  Establishment of a quarterly and annual bonus compensation plan
                 (the "Bonus Plan") for each of the above listed executive
                 officers of the Company. Each executive officer has a separate
                 Bonus Plan, with eligible quarterly payments to that executive
                 officer, if they meet the required criteria for a quarterly
                 bonus payment, which shall be payable the subsequent month and
                 an annual bonus payment to that executive officer, if they meet
                 the required criteria for annual bonus payments, which shall be
                 payable the subsequent month following the close of the
                 Company's books for the year in question. Annual or quarterly

                 Company meets a minimum threshold of 85% of its budgeted EBITDA

                 the executive officer is eligible to receive quarterly and
                 annual payments based on achieving certain targets set forth in
                 the executive officer's particular Bonus Plan during the
                 quarter in question and the year in question. The amount of the
                 quarterly and annual payments will vary depending on the target
                 met and the percentage of meeting such target. The following
                 schedule sets forth the maximum amount payable under the Bonus
                 Plan for each executive officer:

                 Timothy P. Keegan                         50,000
