Rocky Hill, Connecticut ("CII").

                                   BACKGROUND

         HelpMate has certain obligations to CII pursuant to (a) a Financing
Agreement dated June 15, 1995 (the "Financing Agreement"), pursuant to which CII
extended to HelpMate financing in the amount of $500,000, as memorialized by a
Senior Note dated June 14, 1995, in the original principal amount of $500,000
(the "Note"), and (b) a Development Agreement dated December 15, 1986, as
amended February 5, 1996 (the "Development Agreement"), pursuant to which CII
reimbursed HelpMate for certain costs incurred in the development of the
HelpMate(TM) robotic courier, and HelpMate agreed to pay CII royalties on
revenues from the sale or license of HelpMate(TM) products in the amounts and
for the term specified in the Development Agreement.

         In connection with the Financing Agreement, HelpMate has issued to CII
a Warrant dated June 15, 1995 (the "1995 Warrant") to purchase shares of
HelpMate's common stock (the "1995 Warrant Shares"), and has entered into a
Warrant and Stock Put Agreement dated June 15, 1995 with respect the 1995
Warrant and the 1995 Warrant Shares (the "1995 Put Agreement").

         In connection with the February 5, 1996 amendment to the Development
Agreement, HelpMate has issued to CII 50,000 shares of HelpMate's common stock
(the "1996 Shares"), and a warrant (the "1996 Warrant") to purchase shares of
HelpMate's common stock (the "1996 Warrant Shares"), and has entered into a
Warrant and Stock Put Agreement dated February 5, 1996 with respect to the 1996
Warrant and the 1996 Warrant Shares (the "1996 Put Agreement").

         CII has agreed to make certain financial accommodations to HelpMate
pursuant to the provisions of a Creditor Agreement dated this date between CII
and HelpMate (the "Creditor Agreement"). Pursuant to the Creditor Agreement,
HelpMate has issued or will issue to CII (a) in satisfaction of CII's
obligations due under the Financing Agreement and the Development Agreement,
shares of HelpMate's common stock (the "Debt Shares") and a Warrant dated this
date (the "Debt Warrant") to purchase shares of HelpMate's common stock (the

which will become due under the Development Agreement on or about January 31,
1999, respectively, additional shares of common stock (the "1998 Royalty
Shares") and additional Warrants (the "1998 Royalty Warrants") to purchase
shares of HelpMate's common stock (the "1998 Royalty Warrant Shares").

         CII is also the holder of a Warrant dated November 20, 1990 and amended
June 14, 1995 (the "1990 Warrant") to purchase shares of HelpMate's common stock
(the "1990 Warrant Shares").

         In this Agreement, the 1990 Warrant Shares, the 1995 Warrant Shares,
the 1996 Warrant Shares, the Debt Warrant Shares and the 1998 Royalty Warrant
Shares are sometimes referred to individually as a "Warrant Share," and
collectively, as the "Warrant Shares." The 1990 Warrant, the 1995 Warrant, the
1996 Shares, the 1996 Warrant, the Debt Shares, the Debt Warrant, the 1998
Royalty Shares, and the 1998 Royalty Warrant, any warrant or warrants issued
upon any replacement, exchange or transfer of any of the warrants described
above, and the Warrant Shares are collectively referred to as the "Securities"
in this Agreement.

         HelpMate and CII desire that CII shall have the opportunity to sell the
Securities, in whole, to HelpMate, upon the terms set forth in this Agreement.

         NOW THEREFORE, the parties agree as follows:

         1. Right of Holder to Sell the Securities to HelpMate. In the event of
a Breach, as defined below, at any time on or before the ten-year anniversary
date of this Agreement, CII shall have the option of selling to HelpMate all of
the Securities then owned by CII. CII shall exercise its option by delivering to
HelpMate a notice (a "Notice of Put") in the form attached as Exhibit A of this
Agreement, at any time on or prior to 30 days after the ten-year anniversary
date of this Agreement. Upon the receipt of a Notice of Put, HelpMate shall
purchase the Securities then owed by CII upon the terms and conditions set forth
in this Agreement.

         2. Breach of Connecticut Presence Obligations. For the period of ten
(10) years following the date of this Agreement, each of HelpMate and its
subsidiaries shall maintain its principal place of business in the State of
Connecticut, base a majority of its employees in the State of Connecticut, and
conduct a majority of its operations (including manufacturing and production),
directly or through subcontractors, in the State of Connecticut. When used in
this Agreement, the term "Breach" shall be mean a breach by HelpMate of the
covenants set forth in this Paragraph.

         3. Purchase Price. The purchase price for the Securities purchased
under this Agreement (the "Purchase Price") shall be (a) with respect to
Securities consisting of shares of common stock of HelpMate, the Current Market
Value ( as defined in Paragraph 4 below) of each such shares multiplied by the
number of such shares; plus (b) with respect to each unexercised Warrant Share,
the dollar amount, if a positive number, resulting from subtracting the exercise
price of such Warrant Share on the Closing Date from the current Market Value of
one share of common stock of HelpMate.

         4. Current Market Value. As used in this Agreement, the "Current Market
Value" of one share of HelpMate Common Stock shall mean:

         (a) the average of the daily closing prices for the 30 consecutive
business days ending no more than 15 business days before the Closing Date (as
adjusted for any stock dividend, split, combination or reclassification that
took effect during such 30 business day period). The closing price for each day
shall be the last reported sales price regular way or, in case no such reported
sales took place on such day, the last reported bid price regular way, in either
case on the principal national securities exchange on which HelpMate's common
stock is listed or admitted to trading, or as reported by the National
Association of Securities Dealer's Automated Quotations System ("NASDAQ") (or if
HelpMate's common stock is not at the time listed or admitted for trading on any
such exchange, or if the prices of the common stock are not reported by NASDAQ,
then such price shall be equal to the last reported bid price on such day as
reported by The National Quotation Bureau Incorporated, or any similar reputable
quotation and reporting service, if such quotation is not reported by the
National Quotation Bureau Incorporated); or

         (b) If the common stock is not traded in such a manner that the
quotations referred to in subparagraph (a) above are available for the period
required under subparagraph (a), the value determined in good faith by the Board
of Directors of HelpMate, or if such determination cannot be made or is
reasonably objected to by CII within 20 days of its notification thereof, by a
nationally recognized independent investment banking firm (with no present or
past relationship with HelpMate or CII) selected in good faith by the Board of
Directors of HelpMate , or if such selection cannot be made or is reasonably
objected to by CII within 20 days of its notification thereof, by a nationally
recognized independent investment banking firm selected by the American
Arbitration Association in Hartford, Connecticut in accordance with its rules.

         5. Closing. The closing (the "Closing"), of the purchase and sale of
the Securities pursuant to this Agreement shall be held on the date (the
"Closing Date") which is the thirtieth (30th) business day after delivery of the
Notice of Put, or if the Purchase Price has not been determined as of such date,
notwithstanding HelpMate's good faith and reasonable diligence in causing the
determination to be completed, then on a date which is within five business days
after the Purchase Price has been determined. At the Closing, CII will deliver
to HelpMate the certificates and warrants representing all the Securities owned
by CII, and HelpMate will deliver to CII the Purchase Price in cash, by
certified or bank check, or by wire transfer of immediately available funds to
an account designated by CII. In the event that the Closing does not take place
on the thirtieth (30th) business day after the delivery by CII of the Notice of
Put (except to the extent that the reason for the delay is that the Purchase
Price has not yet been determined, and HelpMate has exercised good faith and
reasonable diligence in the pursuing the determination thereof), the unpaid
Purchase Price shall bear interest after the thirtieth (30th) business day (the
"Default Interest") and until the Closing Date at the rate of eight percent (8%)
per annum, and all accrued Default Interest shall be due and payable to CII at
the Closing, together with the Purchase Price.
