Mister A.C. and Vignola understand that the Guidelines determinations will be made by the Court by a preponderance of the evidence standard. Mister A.C. and Vignola understand that although the Court is not ultimately bound to impose a sentence within the applicable Guidelines range, its sentence must be based upon considerations of all relevant sentencing factors set forth in 18 U.S.C. § 3553(a).

13. The United States and Mister A.C. agree and stipulate that the Sentencing Guidelines in effect on the day of sentencing should be applied.

14. The United States and Vignola agree and stipulate that the Sentencing Guidelines in effect on the day of sentencing should be applied.

SENTENCING AGREEMENT

15. Mister A.C. and Vignola understand that the sentences to be imposed on them are within the sole discretion of the sentencing judge. It is understood that the Sentencing Guidelines are not binding on the Court. The defendants acknowledge that their entries of guilty pleas to the charged offense authorizes the sentencing court to impose any sentence, up to and including the statutory maximum sentence. The United States cannot and does not make any promises or representations as to what sentences Mister A.C. and Vignola will receive. The defendants understand that, as provided in Fed. R. Crim. P. 11(c)(3)(B), if the Court does not impose a sentence consistent with the parties' sentencing recommendation, the defendants nevertheless have no right to withdraw their pleas of guilty. However, the United States will inform the Probation Office and the Court of (a) this Agreement; (b) the nature and extent of Mister A.C.'s and Vignola's activities with respect to this case, and all other activities of Mister A.C. and Vignola which the United States deems relevant to sentencing; and (c) the timeliness, nature, extent and significance of Mister A.C.'s and Vignola's cooperation with the United States. In so doing, the United States may use any information it deems relevant, including information provided by Mister A.C. and Vignola both prior and subsequent to the signing of this Agreement. The United States reserves the right to make any statement to the Court or the Probation Office concerning the nature of the offense charged in the attached Information, the participation of Mister A.C. and Vignola therein, and any other facts or circumstances that it deems relevant. The United States also reserves the right to comment on or to correct any representation made by or on behalf of Mister A.C. and Vignola, and to supply any other information that the Court may require.

16. If the United States determines that Mister A.C. has provided substantial assistance in any Federal Proceeding, and has otherwise fully complied with all of the terms of this Agreement, it will file a motion pursuant to U.S.S.G. § 8C4.1 to recommend a downward departure for the substantial assistance Mister A.C. provided to the United States. The United States and Mister A.C. further agree that the fine to be imposed is within the sole discretion of the sentencing judge, but that the Court must consider the factors set forth in U.S.S.G. § 8C3.3(b) in determining Mister A.C.'s ability to pay a fine. The United States and Mister A.C. are free to recommend or argue for any specific sentence to the Court.

17. If the United States determines that Vignola has provided substantial assistance in any Federal Proceeding, and has otherwise fully complied with all of the terms of this Agreement, it will file a motion, pursuant to U.S.S.G. § 5K1.1, advising the sentencing judge of all relevant facts pertaining to that determination and requesting the Court to sentence Vignola in light of the factors set forth in U.S.S.G. § 5K1.1(a)(1)-(5), and thus impose, in the Court's discretion, a sentence below the applicable Sentencing Guidelines ranges for incarceration and fine. The United States and Vignola are free to recommend or argue for any specific sentence to the Court.

18. Vignola and Mister A.C. understand that this Agreement does not in any way affect or limit the right of the United States to respond to and take positions on post-sentencing motions or requests for information that relate to reduction or modification of sentence.

19. Mister A.C. and Vignola acknowledge that the decision whether they have provided substantial assistance in any Federal Proceeding is within the sole discretion of the United States. It is understood that should the United States determine that Mister A.C. or Vignola have not provided substantial assistance in any Federal Proceeding, such a determination will release the United States from any obligation to file a motion pursuant to U.S.S.G. §§ 8C4.1 and 5K1.1, but will not entitle Mister A.C. and/or Vignola to withdraw their respective guilty plea once it has been entered. Mister A.C. and Vignola further understand that whether or not the United States files its motions pursuant to U.S.S.G. §§ 8C4.1 and 5K1.1, the sentence to be imposed on them remains within the sole discretion of the sentencing judge.

20. Mister A.C. and Vignola understand and agree that should the conviction following their pleas of guilty pursuant to this Agreement be vacated for any reason, then any prosecution that is not time-barred by the applicable statute of limitations on the date of the signing of this Agreement (including any counts that the Government has agreed to dismiss at sentencing pursuant to this Agreement) may be commenced or reinstated against them, notwithstanding the expiration of the statute of limitations between the signing of this Agreement and the commencement or reinstatement of such prosecution. It is the intent of this Agreement to waive all defenses based on the statute of limitations with respect to any prosecution that is not time-barred on the date that this Agreement is signed.

After conferring with their attorneys and considering all available alternatives, the Defendants have made a knowing and voluntary decision to enter into this Plea Agreement.

22. The Defendants hereby acknowledge that they have accepted this Agreement and decided to plead guilty because they are in fact guilty.

The United States has made no promises or representations to the Defendants as to whether the Court will accept or reject the recommendations contained within this Agreement.

VIOLATION OF PLEA AGREEMENT

24. Mister A.C. and Vignola agree that should the United States determine in good faith that Mister A.C. and/or Vignola have given false, misleading, or incomplete information or testimony, or that Mister A.C. and/or Vignola have failed in any other way to fulfill any of the obligations set out in this Agreement, the United States shall notify counsel for Mister A.C. and/or Vignola in writing by personal or overnight delivery or facsimile transmission of its intention to void any of its obligations under this Agreement (except its obligations under this paragraph), and Mister A.C. and/or Vignola will be subject to prosecution for any federal criminal violation of which the United States has knowledge, including but not limited to the substantive offenses relating to the investigation resulting in this Agreement. It is the intent of this Agreement to waive all defenses based on the statute of limitations with respect to any prosecution that is not time-barred on the date that this Agreement is signed.

25. If Mister A.C. and/or Vignola violate any provision of this Agreement, they agree that any documents, statements, information, testimony or evidence provided by Mister A.C. and/or Vignola whether before or after the execution of this Agreement, and any leads derived therefrom, shall be admissible in evidence in any and all criminal proceedings hereafter brought against Mister A.C. and/or Vignola, and that neither will assert a claim under the United States Constitution, any statute, Rule 410 of the Federal Rules of Evidence, or any other federal rule, that such evidence, or any leads therefrom, should be suppressed.
