Receiving Service: Entire Company Locations of Receiver: Various Description: Provide routine processing of employee payroll and distribution of pay checks/EFT receipts utilizing the PeopleSoft Payroll module. Term: Anticipated to end by 7/31/2000, but in no case beyond 12/31/2000. Monthly Base Fee: $15,257 (See attached memo) Additional Charges for Additional Services Provided by Olin Corporation: To be negotiated on an as-needed basis Additional Charges for Additional Software Licensing: All additional licensing costs will be paid by Arch Chemical All Charges for Ceridian Tax Services For Arch Chemicals: All invoices to be paid by Arch Chemicals All Charges for Services Related to PeopleSoft: To be negotiated on an as-needed basis TO: Tony Sandonato Arch Chemicals December 8, 1999 FR: Dennis McGough Olin Corporation C.C.: Rose Gibson RE: Payroll Services for Arch Chemicals for 2000 This memo confirms our discussions regarding payroll services for Arch Chemicals beyond 1999. For 1999, Olin Corporation has been charging Arch Chemicals $18,000/month for normal payroll services, including the processing and distribution of all normal payrolls (approximately 67 individual payrolls per month), a once-per-year special payroll (annual bonuses, etc.), a reasonable number of special check requests, tax withholding and distribution services and W2 preparation and distribution. Ceridian Tax Service was paid directly by Arch Chemicals. Arch would like to continue our payroll services arrangement through the year 2000 because of concerns with potential Y2K issues, (including leap year issues) that may arise. **For 2000, the fee to Arch Chemicals would be $15,257/month, which represents a 3.9% increase over 1999 plus modifications to the payroll process stated in the footnote below. This fee arrangement ANTICIPATES THE SAME LEVEL OF SERVICE as 1999. Therefore, it does not include the monthly fee to Ceridian Tax Service. This fee will be paid to the vendor directly from Arch Chemicals. Also, it does not include the costs related to PeopleSoft, which will be billed separately. We anticipate that an outside consultant will complete the PeopleSoft year-end work. Olin Corporation will bill you the costs it incurs to complete this activity. If, as we have discussed, you are able to reduce the number of payrolls processed each month, Arch Chemicals will enjoy a negotiated reduction in fees, commensurate with the level of decrease. If the number of payrolls increases, the fee will increase commensurate with the increase. Fees for special services not within the scope of this agreement will be negotiated at the time these services are requested. Olin Corporation or Arch Chemicals may terminate this agreement upon three months written notice to the other. If this agreement is terminated prior to the end of a calendar year, Olin Corporation agrees to provide all necessary year-end payroll processing services reflecting transactions through the date of termination and contract for necessary PeopleSoft year-end services, provided that Arch Chemicals agrees to pay the appropriate fees for both services. If the foregoing is agreeable to you, please indicate by signing this memo below. These changes will be incorporated into the Payroll Processing & Distribution Services section of the Olin/Arch Transition Services Agreement. **THIS NEW MONTHLY CHARGE IS BASED ON PENDING CHANGES IN CURRENT PAYROLL PROCESSING. THIS REPRESENTS THE PROPOSED CHANGE OF WEEKLY TO BI-WEEKLY FOR 4 PAYROLLS. IT ALSO REPRESENTS A 75% REDUCTION IN PRINTING AND POSTAGE CHARGES FOR EFT STATEMENTS.
