AMENDMENT TO STOCK PURCHASE AGREEMENT


This AMENDMENT TO STOCK PURCHASE AGREEMENT is made the 12th day of 
August, 1997, with an effective date as described below, by and 
between UNIVERSAL DOCUMENT MANAGEMENT SYSTEMS, INC. (formerly 
"MedPlus Acquisition Corp.") (the "Purchaser"), an Ohio 
corporation and a wholly-owned subsidiary of MedPlus, Inc. 
("MedPlus"), with its principal offices located at 8805 Governor's 
Hill Drive, Cincinnati, Ohio  45249, JAY AND JUDY HILNBRAND, 
individuals residing at 617 Sonora Ct., Cincinnati, Ohio 45215 
("Hilnbrand") and ROBERT C. WEISS, an individual residing at 5632 
Julmar, Cincinnati, OH  45238 ("Weiss") (Hilnbrand and Weiss are 
collectively referred to as the "Sellers").

                          W I T N E S S E T H:

WHEREAS, the Purchaser and the Sellers entered into a Stock 
Purchase Agreement dated December 29th, 1995 (the "Initial 
Agreement") pursuant to which the Sellers sold to the Purchaser 
and the Purchaser purchased from the Sellers all of the common 
stock of HWB, Inc. owned by  the Sellers (the "HWB Stock"); and

WHEREAS, the consideration for the HWB Stock, which the parties 
agree was a capital asset, was to be paid to the Sellers over a 
period of three years in the form of MedPlus common stock and/or 
cash and was to be calculated based on the revenues of the 
Purchaser during such three year period (the "Earn-Out 
Consideration"); and

WHEREAS, the Purchaser is planning to combine with certain CAD 
resellers and conduct an initial public offering of its common 
stock (the "IPO") with an effective date which is on or before 
December 31, 1997 (the "IPO Date");and

WHEREAS, if the IPO occurs, then following the IPO, MedPlus will 
no longer be the sole shareholder of the Purchaser; and

WHEREAS, if the IPO occurs, then as a result of the change in 
ownership and structure of the Purchaser following the IPO, the 
Purchaser and the Sellers desire to amend the Initial Agreement 
with respect to the Earn-Out Consideration to clarify the revenues 
as to which it applies and to provide for additional time during 
which the Earn-Out Consideration may be paid to the Sellers and to 
allow a portion of such consideration to be paid in the form of 
the Purchaser's common stock instead of MedPlus' common stock; and

WHEREAS, the Purchaser and Sellers agree that this Amendment to 
Stock Purchase Agreement shall only become effective in the event 
of the IPO and on the IPO Date, if any.

NOW THEREFORE, in consideration of the foregoing and the mutual 
agreements set forth herein, the parties, intending to be legally 
bound, agree as follows:
On the IPO Date, Schedule 2 to the Initial Agreement shall be 
amended to read in its entirety as follows:


                     "Schedule 2
                Stock Purchase Consideration

On January 1, 1998, the Purchaser shall pay to the Sellers 
$390,000 (of which $311,922 shall be paid to Hilnbrand and $78,078 
shall be paid to Weiss).   So long as each of Jay Hilnbrand and 
Robert C. Weiss remains employed by the Purchaser until at least 
December 31, 1998, the following consideration shall be payable to 
Sellers no later than March 31, 1999, 2000 and 2001, respectively, 
as follows (the `Earn-Out Consideration'):

If, during any of the three periods described below (the `Earn-Out 
Periods'), the Audited Net Revenue (as defined below) of the 
Purchaser exceeds a certain amount, as listed below, with respect 
to that Earn-Out Period (the `Earn-Out Threshold'), then Purchaser 
shall pay to the Sellers an aggregate amount equal to 99.9% of the 
`Payment Amount' listed below (the `Annual Payment').  In no event 
shall the cumulative aggregate of the Earn-Out Consideration for 
all three Earn-Out Periods exceed $2,610,000.

The IPO Date through
December 31, 1998          $1,750,000            $1.00 for each
                                                dollar of Audited 
                                                Net Revenue over  
                                                  $1.75 million

January 1, 1999 through
December 31, 1999            2,750,000           $1.00 for each
                                              dollar of Audited
                                               Net Revenue over
                                                $2.75 million

January 1, 2000 through
December 31, 20003           3,750,000           $1.00 for each
                                              dollar of Audited
                                               Net Revenue over
                                                $3.75 million

For purposes hereof, `Audited Net Revenue' of the Purchaser shall 
mean all the gross revenues related to the Purchaser's Step2000 
software product (including, but not limited to, licensing and 
maintenance fees and consulting and application building fees with 
respect to Step2000), minus returns and allowances related to the 
Purchaser's Step2000 software product and minus the amount of 
accounts receivable written off as uncollectible during the period 
in question which are related to the Purchaser's Step2000 software 
product and which are either over 180 days old or are owed by a 
debtor which has declared bankruptcy or has otherwise admitted its 
insolvency in a public filing.  In the event that the amount of 
any fees charged by Purchaser to any person who is an affiliate of 
Purchaser or MedPlus are less than the ordinary rates charged for 
customers who are not affiliates in arms-length transactions, then 
the amount of Audited Net Revenues for purposes of calculating the 
Earn-Out Consideration shall be increased by the amount by which 
the ordinary rates exceed the actual rates charged.  All payments 
of the Earn-Out Consideration shall be made in cash or, at the 
election of the Purchaser, in a combination of cash and the 
Purchaser's common stock, provided that the common stock component 
of any payment of the Earn-Out Consideration shall not exceed 50%. 
 To the extent the Purchaser's common stock is used to make any 
payment, each share so issued shall be deemed to have a value 
equal to the average of the closing price per share of the 
Purchaser's common stock on the Nasdaq National Market for each of 
the 20 trading days preceding the payment date.  Notwithstanding 
the foregoing, payments may only be made in the form of the 
Purchaser's common stock if at the time of issuance thereof there 
is a registration statement effective under the Securities Act of 
1933 covering a resale of such shares by Sellers, the cost of 
which shall not be the responsibility of Sellers.  The term 
`Purchaser's common stock' shall not include any securities of the 
Purchaser other than its common stock, or any securities of any 
successor of the Purchaser. 

The percentage of each Annual Payment of Earn-Out Consideration to 
which each Seller is entitled is set forth as follows:  Hilnbrand, 
79.98%; Weiss 20.02%."

IN WITNESS WHEREOF, the parties hereto have caused this 
Amendment to Stock Purchase Agreement to be executed as of the day 
and year first above written.
