          , 2004, and the related letter of transmittal (which together

     Enclosed are copies of the following documents:

          1. Prospectus, dated           , 2004;

          2. Letter of Transmittal (together with accompanying Substitute Form

     Outstanding Notes in your name or in the name of your nominee, with space
     provided for obtaining such client's instruction with regard to the
     Exchange Offer.

     We urge you to contact your clients promptly. Please note that the Exchange
Offer will expire on the Expiration Date unless extended.

     The Exchange Offer is not conditioned upon any minimum number of
Outstanding Notes being tendered.

     Pursuant to the letter of transmittal, each holder of Outstanding Notes
will represent to Argo-Tech that:

          (i) any Exchange Notes that the holder will acquire in exchange for
     Outstanding Notes will be acquired in the ordinary course of business of
     the holder;

          (ii) the holder has no arrangement or understanding with any person to
     participate in a distribution, within the meaning of the Securities Act, of
     any Exchange Notes issued to the holder;

          (iii) the holder is not an "affiliate" (as defined in Rule 405 under
     the Securities Act) of Argo-Tech Corporation;

          (iv) the holder has full power and authority to tender, exchange,
     sell, assign and transfer the tendered Outstanding Notes;


          (v) Argo-Tech will acquire good, marketable and unencumbered title to
     the tendered Outstanding Notes, free and clear of all liens, restrictions,
     charges and encumbrances; and

          (vi) The Outstanding Notes the holder tenders for exchange are not
     subject to any adverse claims or proxies.

     If the holder is a broker-dealer that will receive Exchange Notes for its
own account in exchange for notes that were acquired as a result of
market-making or other trading activities, it will represent that the
Outstanding Notes were acquired as a result of market-making activities or other
trading activities, and it will acknowledge that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale of
those Exchange Notes. By acknowledging that it will deliver and by delivering a
prospectus meeting the requirements of the Securities Act in connection with any
resale of those Exchange Notes, the broker-dealer is not deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.

     The enclosed Letter to Clients contains an authorization by the beneficial
owners of the Outstanding Notes for you to make the foregoing representations.

     Argo-Tech will not pay any fee or commission to any broker or dealer to any
other persons (other than the Exchange Agent) in connection with the
solicitation of tenders of Outstanding Notes pursuant to the Exchange Offer.
Argo-Tech will pay or cause to be paid any transfer taxes payable on the
transfer of Outstanding Notes to it, except as otherwise provided in Instruction
6 of the enclosed letter of transmittal.

undersigned.
