Final answer:
Section 1 of the partnership agreement is valid, while Section 2 is invalid under RUPA.
Step-by-step explanation:
Under the Revised Uniform Partnership Act (RUPA), Section 1 of the partnership agreement is valid. This section allows for the admission of a new partner if at least 75% of the current partners vote to admit the new partner. This provision is in line with RUPA's requirement for partner admission.
However, Section 2 of the partnership agreement is invalid under RUPA. RUPA does not recognize ordinary negligence as a breach of a partner's duty of care to the partnership. Instead, RUPA imposes a duty of loyalty and a duty of care on partners, requiring them to act in the best interest of the partnership and with a certain standard of care and skill.
