         FOR VALUE RECEIVED, the undersigned, STANADYNE CORPORATION
("Stanadyne") and PRECISION ENGINE PRODUCTS CORP. ("Precision"; and together

of the United States of America and in immediately available funds, the amount
of TWENTY-FIVE MILLION DOLLARS ($25,000,000). All capitalized terms used but not
otherwise defined herein have the meanings given to them in the Loan Agreement
(as hereinafter defined).

         This Term Note is the Term Note issued pursuant to that certain Loan
and Security Agreement dated the date hereof (including all exhibits and
schedules thereto and as from time to time may be amended, restated, renewed,

under which the loans evidenced hereby are made and are to be repaid.

         The principal amount of the indebtedness evidenced hereby shall be

Interest thereon shall be paid until such principal amount is paid in full at

incorporated herein by reference.

         This Term Note is secured by the Collateral and is entitled to all of
the benefits and rights as set forth in the Loan Agreement and the Other
Documents. At the time any payment is due hereunder, at its option, Agent may
charge the amount thereof to any account of any Debtor maintained by Agent.

         If any payment of principal or interest is not made when due hereunder,
of if any other Default or Event of Default shall occur for any reason, or if

         Each Debtor hereby (i) waives diligence, demand, presentment, protest

institute suit in order to enforce payment of this Term Note and (iii) consents
to any one or more extensions or postponements of time of payment, release,
surrender or substitution of collateral security, or forbearance or other
indulgence, without notice or consent. The pleading of any statute of
limitations as a defense to any demand against Debtor is expressly hereby waived
by each Debtor. Upon or after maturity of this Term Note, or any Event of
Default or termination of the Loan Agreement, Agent and each Lender, shall have
the right, subject to the terms of the Loan Agreement, but not the obligation,

Debtor.

         No resort to any Collateral for payment shall be required prior to the
enforcement hereof against any Debtor and any guarantors or endorsers hereof.

         If any term or provision of this Term Note shall be held invalid,
illegal or unenforceable, the validity of all other terms and provisions hereof
shall in no way be affected thereby.

Debtor with respect to any of the Obligations, this Term Note or any related
