<s>[INST] A company is getting ready for negotiations with a major supplier. The purchasing department has gathered the following information regarding the current market conditions: 

(1) The force majeure clause in the existing contract is ambiguous with regard to product liability and replacement costs. 
(2) The relationship between the company and supplier has been strained due to disagreements on the interpretation of the force majeure clause, specifically regarding product liability and replacement costs. 
(3) The supplier is experiencing financial difficulties, and there are rumors of possible restructuring. 
(4) End-users of the product are beginning to shift demand towards alternative products with lower environmental impact. 

The purchasing department has been told that its goal for the upcoming negotiations is to ensure that the contract reflects a shifting of the risk of product liability and replacement costs back to the supplier. What negotiation tactics might help achieve this goal given the current market conditions?

To answer this question, explain `threats` or `weaknesses` that can be expressed or emphasized about the supplier during negotiation; `opportunities` that can be utilized to influence the outcome to the company's advantage; `leverage` that can be used to persuade the supplier to accept the desired terms, and `alternatives` to be explored if the negotiations fail.[/INST]
