                           REVOLVING LOAN - GRID NOTE


$200,000.00                  Westerville, Ohio                February 28, 1997

     FOR VALUE RECEIVED, the undersigned promises to pay to the order of
NETMED, INC. (hereinafter called the "Lender," which term shall include any
holder hereof) at such place as the Lender may designate, the sum of
TwoHundred Thousand Dollars ($200,000.00) or so much thereof as shall have
been advanced by the Lender at any time and not hereafter repaid (hereinafter
referred to as "Principal Sum") together with interest as hereinafter
provided and payable at the times and in the manners hereinafter provided.
The proceeds of the loan evidenced hereby may be advanced, and repaid in
partial amounts during the term of this revolving note (this "Note") and
prior to maturity.   Each such advance shall be made to the undersigned upon
receipt by the Lender of the undersigned's application therefor and
disbursement instructions, which shall be in such form as the Lender shall
from time to time prescribe.  The Lender shall be entitled to rely on any
oral or telephonic communication requesting an advance and/or providing
disbursement instructions hereunder, which shall be received by it in good
faith from anyone reasonably believed by the Lender to be the undersigned, or
the undersigned's authorized agent.  The undersigned agrees that all Advances
(as such term is defined in the Investment Agreement referenced below) made
by the Lender and payments by the undersigned will be evidenced by entries
made by the Lender on the grid or grids attached hereto, and the undersigned
further agrees that such entries shown on the grid or grids attached hereto
shall be rebuttably presumptive evidence of the amount of the Principal Sum,
any and all advances and payments thereof.  Copies of such entries shall be
provided by Lender to the undersigned within a reasonable time after they are
made.   Each request for an advance shall constitute a warranty and
representation by the undersigned that no event of default hereunder, under
the Investment Agreement, or under any related loan documents has occurred
and is continuing and that no event or circumstance which would constitute
such an event of default, but for the requirement that notice be given or
time elapse or both, has occurred and is continuing.

     This Note is executed and the advances contemplated hereunder are to be
made pursuant to an Investment Agreement by and between the undersigned and
the Lender of even date, and all amendments, modifications, and supplements
thereto from time to time (the "Investment Agreement"), and all the
covenants, representations, agreements, terms, and conditions contained
therein, including but not limited to additional conditions of default, are
incorporated herein as if fully rewritten.

INTEREST

     Interest will accrue on the unpaid balance of the Principal Sum until
paid at a fixed rate of interest equal to eight and one-half percent (8.50%)
per annum.

     All interest shall be calculated on the basis of a 365 day year for the
actual number of days the Principal Sum or any part thereof remains unpaid.

MANNER OF PAYMENT

     The Principal Sum shall be payable on December 31, 1998, and accrued
interest shall be due and payable at maturity, whether by demand,
acceleration or otherwise.

     before five days after the date such payment is due; or

          (c)  an "Event of Default" under the Investment  Agreement shall have

maturity of the obligations evidenced hereby, which obligations shall become

disposition, or modification of all the obligations evidenced hereby or any

guaranties now held or hereafter acquired, or substitute other collateral,
security or other guaranties, and no such action will release, discharge or
modify the duties of the undersigned hereunder.  The undersigned agrees that
