Esto es más que una plea bargain ya que el sujeto tiene que colaborar con las autoridades para conseguir su rebaja. Con la plea bargain simple, puede ser que el acusado se reconozca culpable de una infracción menor de la que se le imputa así como cumplir con la asitencia de ciertos programas (control de la ira, deshabituación alcohólica, por ej.) o bien cumplir con la libertad vigilada por haber recibido una condena condicional. Sin embargo la dilación premiada significa que el acusado además tendrá que aportar una información sobre los ilícitos y sus autores de los cuales tenga conocimiento.

Según el enlace que nos has proporcionado, se hace la comparación entre la dilación premiada y la colaboración eficaz del Perú. Esta figura procesal no solo implica una rebaja de la pena sino que el acusado que presta su conformidad debe colaborar con las autoridades que procuran perseguir penalmente a otros delincuentes dentro del mismo ámbito criminal.

Plea and Cooperation Agreement from a US Fderal District
DEFENDANT’S OBLIGATIONS
A. Waiver of Indictment and Guilty Plea: The defendant will waive indictment by grand jury, waive venue, and plead guilty to a three-count Information, substantially in the form attached hereto as Exhibit B, charging him with conspiring to conduct the affairs of an enterprise through a pattern of racketeering activity in violation of 18 U.S.C. § 1962(d); money laundering in violation of 18 U.S.C. § 1957; and price fixing in violation of 15 U.S.C. § 1. The defendant agrees that he is in fact guilty of those charges and that the facts set forth in the Factual Basis attached hereto as Exhibit A are true and accurate.
B. Restitution: The Mandatory Victim Restitution Act requires the Court to order restitution to the victims of certain offenses.

Defendant further agrees that he will not seek to discharge any restitution obligation or any part of such obligation in any bankruptcy proceeding.
C. Special Assessment: The defendant agrees to pay a special assessment of $300 at the time of sentencing by delivering a check or money order payable to the United States District Court to the United States Probation Office immediately before the sentencing hearing.
D. Agreement to Cooperate: The defendant agrees to cooperate fully with the government and any other federal, state, or local law enforcement agency, as directed by the government. As used in this Agreement, “cooperation” requires the defendant: (1) to respond truthfully and completely to all questions, whether in interviews, in correspondence, telephone conversations, before a grand jury, or at any trial or other court proceeding; (2) to attend all meetings, grand jury sessions, trials, and other proceedings at which the defendant’s presence is requested by the government or compelled by subpoena or court order; (3) to produce voluntarily any and all documents, records, or other tangible evidence requested by the government; (4) not to participate in any criminal activity while cooperating with the government; and (5) to disclose to the government the existence and status of all money, property, or assets, of any kind, derived from or acquired as a result of, or used to facilitate the commission of, the defendant’s illegal activities or the illegal activities of any conspirators.
