Contractual Commitments

We enter into contracts in the normal course of business with contract research organizations (“CROs”), contract manufacturing organizations (“CMOs”), academic institutions and other third parties for preclinical and clinical research studies, testing and manufacturing services. These contracts generally do not contain minimum purchase commitments and are cancellable by us upon prior written notice, although purchase orders for preclinical materials are generally non-cancellable or have cancellation penalties. Payments due upon cancellation consist primarily of payments for services provided or expenses incurred, including non-cancellable obligations from our service providers, up to the date of cancellation or upon the completion of a manufacturing run.

Litigation and Claims

From time to time, we may be party to litigation, arbitration, claims or other legal proceedings in the course of our business. The outcome of any such legal proceedings, regardless of the merits, is inherently uncertain. In addition, litigation and related matters are costly and may divert the attention of our management and other resources that would otherwise be engaged in other activities. If we were unable to prevail in any such legal proceedings, our business, results of operations, liquidity, and financial condition could be adversely affected.

Indemnifications Obligations

We entered into indemnification agreements with our officers and directors that require us to indemnify such individuals for certain events or occurrences while each such officer or director is, or was, serving at our request in such capacity. The maximum potential future payments we could be required to make is, in many cases, unlimited. We have directors’ and officers’ liability insurance coverage that limits its exposure and enables us to recover a portion of any future amounts to be paid.
