                                                        Andrew P. Gaillard, Esq.
                                                                   June 25, 2001



II.     The Penalties

        This offense carries a maximum penalty of 5 years imprisonment and a
fine. The defendant also is subject to the alternative fine provision of 18
U.S.C. Section 3571. Under this section, the maximum fine that may be imposed on
the defendant is the greatest of the following amounts: (1) twice the gross gain
to the defendant resulting from the offense; and (2) twice the gross loss
resulting from the offense; or (3) $500,000.

        In addition, the defendant is obligated by 18 U.S.C. Section 3013 to pay
a special assessment of $400.00 on each count of conviction. The defendant
agrees to pay the special assessment to the Clerk of the court on the day of
sentencing.

        Finally, unless otherwise ordered, should the Court impose a fine of
more than $2,500 as part of the sentence, interest will be charged on the unpaid
balance of a fine amount not paid within 15 days after the judgment date. 18
U.S.C. Section 3612(f). Other penalties and fines may be assessed on the unpaid
balance of a fine pursuant to 18 U.S.C. Sections 3571 (h), (I) and Section
3612(g).

III.    Sentence Agreement

        The Government and the defendant have agreed, pursuant to Federal Rule
of Criminal Procedure 11(e)(1)(C), that the following sentence is an appropriate
disposition of this case:

A.      Fine

        In light of the defendant's financial condition, the parties agree that
restitution and a separate but related civil settlement, as set forth below, is
appropriate in lieu of a criminal fine in this matter.

B.      Restitution

        The defendant agrees to make restitution in the amount of $5,000,000.00
($5 Million Dollars) to the United States, the victim of its criminal conduct.

Million within thirty (30) days of the plea; $1.5 Million on or before June 30,

                                                    Stanley A. Twardy, Jr., Esq.
                                                        Andrew P. Gaillard, Esq.
                                                                   June 25, 2001


        The defendant understands that if it fails to make such agreed-upon
restitution that the Government may seek to void this agreement. The order of
restitution shall be a condition of probation or supervised release. Failure to
pay restitution may also result in the defendant's re-sentencing to any sentence
which might originally have been imposed by the Court. See 18 U.S.C. Section
3614.

        The Government notes that, contemporaneous with this plea, the defendant
has negotiated and will enter into a separate civil settlement regarding false
claims in the amount of $11,500,000.00 ($11.5 Million Dollars), with credit
allowed for $5,000,000.00 to be ordered and paid as restitution in this case. As
part of the Civil Settlement, the defendant will enter into a Corporate
Integrity Agreement to ensure future compliance.

C.      Probation

        The defendant will be on probation for a period of three years from the
date of sentencing.

IV.     Sentencing Guidelines

        As noted above, the parties have reached agreement as to an appropriate
sentence to be imposed.

                A.      Applicability

        The defendant understands that the Sentencing Reform Act of 1984 and the
Sentencing Guidelines apply in this case. The defendant understands that the
Court is required to consider any applicable Sentencing Guidelines but may
depart from those Guidelines under some circumstances. The defendant expressly
understands that the Sentencing Guideline determinations will be made by the
Court, based upon input from the defendant and the Government. The defendant
further understands that it may withdraw its guilty plea if its sentence or the
Guideline application is other than the parties have agreed and set forth
herein.

                B.      Information to the Court

        It is expressly understood that the Government will discuss the facts of
this case with the United States Probation Office

in this case, and to enter into and comply with all provisions of this
agreement. The resolution shall further certify that Jason Sholder, President of
Raytel Cardiac Services, Inc., is authorized to take these actions, and that all
corporate formalities required for such authorization, including approval by the
defendant's directors, have been observed.

defendant to waive indictment, to enter a plea of guilty, and to receive the
imposition of sentence by the Court.

                                                        Andrew P. Gaillard, Esq.
                                                                   June 25, 2001


applicable to the pacemaker testing business, and the anti-kickback laws and/or
regulations.

        If an individual raises an assertion of the advice of counsel defense in

defendant.

VII.    Waiver of Rights

        A.      Waiver of Right to Indictment

        The defendant understands that it has the right to have the facts of
this case presented to a federal grand jury, consisting of between sixteen and
twenty-three citizens, twelve of whom would have to find probable cause to
believe that it committed the offense set forth in the information before an
indictment could be returned. The defendant expressly acknowledges that it is
waiving its right to be indicted knowingly and intelligently.

        B.      Waiver of Trial Rights and Consequences of Plea

to persist in that plea if it has already been

                                                        Andrew P. Gaillard, Esq.
                                                                   June 25, 2001


made, the right to be tried by a jury with the assistance of counsel, the right
to confront and cross-examine the witnesses against it, the right not to be
compelled to incriminate itself, and the right to compulsory process for the
attendance of witnesses to testify in its defense. The defendant understands
that by pleading guilty it waives and gives up those rights and that if the plea
of guilty is accepted by the Court, there will not be a further trial of any
kind.

        The defendant understands that if it pleads guilty, the Court may ask
its authorized representative questions about each offense to which it pleads
guilty, and if he answers those questions falsely under oath, on the record, and
in the presence of counsel, his answers may later be used against him in a
prosecution for perjury or making false statements.

VIII.   Waiver of Statute of Limitations

        The defendant understands and agrees that should the conviction
following defendant's plea of guilty pursuant to this plea 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 plea agreement
(including any indictment or counts the government has agreed to dismiss at
sentencing pursuant to this plea agreement) may be commenced or reinstated
against defendant, notwithstanding the expiration of the statute of limitations
between the signing of this plea agreement and the commencement or reinstatement
of such prosecution. The defendant agrees to waive all defenses based on the
statute of limitations with respect to any prosecution that is not time-barred
on the date the plea agreement is signed.

IX.     Acknowledgment of Guilt; Voluntariness of Plea

        The defendant acknowledges that it is entering into this agreement and
is pleading guilty freely and voluntarily because it is guilty. The defendant
further acknowledges that it is entering into this agreement without reliance
upon any discussions between the Government and it (other than those described
in the plea agreement letter), without promise of benefit of any kind (other
than the concessions contained in the plea agreement letter), and without
threats, force, intimidation, or coercion of any kind. The defendant further
acknowledges its understanding of the nature of the offense to

which it is pleading guilty, including the penalties provided by law. The
defendant also acknowledges its complete satisfaction with the representation
and advice received from its undersigned attorney. The defendant and its
undersigned counsel are unaware of any conflict of interest concerning counsel's
representation of the defendant in the case. Finally, the defendant acknowledges
that the undersigned representative is authorized and empowered to act in this
matter on behalf of the defendant corporation.

X.      Scope of Agreement

        The defendant acknowledges and understands that this agreement is
limited to the undersigned parties and cannot bind any other federal authority,
or any state or local authority. The defendant acknowledges that no
representations have been made to it with respect to any civil or administrative
consequences that may result from this plea of guilty because such matters are
solely within the province and discretion of the specific administrative or
governmental entity involved. Finally, the defendant understands and
acknowledges that this agreement has been reached without regard to any civil
tax matters that may be pending or which may arise involving it.

XI.     Collateral Consequences

        The defendant further understands that it will be adjudicated guilty of
the offense to which it has pleaded guilty and may thereby be deprived of
certain federal benefits and rights. The defendant understands that the
Government reserves the right to notify any state or federal agency by whom it
is licensed, or with whom it does business, of the fact of its conviction.

XII.    Satisfaction of Federal Criminal Liability; Breach

        The defendant's guilty plea, if accepted by the Court, will satisfy the
federal criminal liability of the defendant for all violations of the federal
health care and related laws now known to this office and the Office of
Inspector General of the Department of Health and Human Services ("HHS-OIG")
that could be brought in the District of Connecticut.

        The defendant understands that if, before sentencing, it violates any
term or condition of this agreement, engages in any

criminal activity, the Government may void all or part of this agreement.

XIII.   Other Promises

        The defendant acknowledges that no other promises, agreements, or
conditions have been entered into other than those set forth in this plea
agreement, and none will be entered into unless set forth in writing, signed by
all the parties.

        This letter shall be presented to the Court, in open court, and filed in
