We would also be happy to schedule a call with the deal teams to walk through the draft or discuss any preliminary questions before your firm begins its detailed review. We have availability early next week and can coordinate a time that works for all parties.

Finally, a brief reminder that the attached draft is confidential and subject to the terms of the Exclusivity Agreement and any applicable confidentiality agreements between the parties. We would ask that distribution be limited accordingly.

Please do not hesitate to reach out if you have any preliminary questions. We look forward to working with you on this transaction.
