sample="quota" bates="2025688065" isource="pm" decade="1980" class="ui" date="19860301" TH1080 Addendum 1 to the Agreement dated 1 March 1986 between Tobacco Advisory Council and Hazleton Laboratories Europe Ltd. 1. The value of the original contract was £190761, thereafter, further work was requested and is now included in the protocol attached and the additional estimated charges were notified to TAC on 6 March 1986 by Dr. T.H. Houseman. The total contract value will now remain fixed subject to the provisions of Clause 5 of the main contract providing the Contract Work has been completed in accordance with the protocol by 28 February 1987. Any changes to the protocol or extensions to the time period of completion will incur further variations to the contract sum. 2. The Contract Work was started on 22 April 1986. The delays from 1 March 1986 to this date are due to circumstances completely outside the control of Hazleton. 3. Both parties confirm (as indicated in clause 3 of the main contract) that the likely duration of the Contract Work is a period of 12 months. 4. Prior to 22 April 1986 HLE carried out additional preparatory work at the request of TAC which has been charged against the "Estimated Charges". 5. Taking into account the foregoing both parties therefore acknowledge that the Contract Work is likely to extend beyond 28 February 1987 and that additional costs to cover the work being done before the start of the Contract Work will be chargeable at that time.
