The fourth step in negotiating an alliance partnership is to negotiate the terms and conditions of the alliance. This means agreeing on the financial and operational aspects of the alliance, such as the revenue sharing, the cost sharing, the risk sharing, the intellectual property rights, the confidentiality agreements, and the exit clauses. It also means aligning the expectations and incentives of each partner, such as the commitment level, the contribution level, the reward level, and the penalty level. By negotiating the terms and conditions, both parties can create a fair and balanced deal that reflects their interests and values.
