Maryland Code, Commercial Law § 22-705

(1) A party may refuse a tender of a copy which is a material breach as to that copy, but refusal of that tender does not cancel the contract.

(2) In a case governed by paragraph (1) of this subsection, the tendering party may cure the breach by seasonably providing a conforming copy before the breach becomes material as to the whole contract.

(3) A breach that is material with respect to a copy allows cancellation of the contract only if the breach cannot be seasonably cured and is a material breach of the whole contract.
