      This Amendment No. 1 relates to the Common Stock, par value $.01 per share
("Common Stock"), issued by Icad, Inc., a Delaware corporation (the "Company"),
formerly know as Howtek, Inc., whose principal executive offices are located at
6405 Congress Avenue, Boca Raton, FL 33487. Except as modified hereby, there has
been no change in the information previously reported in the Schedule 13D dated
June 7, 2002 of Robert Howard (the "Reporting Person").

Item 3.  Source and Amount of Funds or other Consideration.

      2,000,000 shares of Common Stock reported in Item 5 as beneficially owned
by the Reporting Person were acquired by RH Ventures Inc. ("RH"), a corporation
of which the Reporting Person is an officer, sole director and sole shareholder.
These shares were acquired by RH in exchange for 1,600,000 shares of Intelligent
Systems Software, Inc. ("ISSI") Common Stock owned by RH, pursuant to the terms
of the merger of ISSI with and into the Company (the "Merger'), which was
consummated on June 28, 2002. 100,000 shares of Common Stock reported in Item 5
as beneficially owned by the Reporting Person represent shares that the
Reporting Person may acquire from the Company pursuant to the conversion of a
Convertible Revolving Credit Promissory Note in the principal amount of $250,000
payable by the Company to the Reporting Person (the "Note") which represents a
loan made by the Reporting Person to the Company on June 6, 2002. The Reporting
Person used his personal funds to advance to the Company the loan that was
evidenced by the Note.

Item 4.  Purpose of Transaction.

      The shares reported in Item 3 herein were acquired by the Reporting Person
for investment purposes. The Reporting Person may make purchases of Common Stock
from time to time and may dispose of any or all of the shares of Common Stock
beneficially owned by him (to the extent he has dispositive power over such
shares) at any time. The Reporting Person has no plans or proposals which relate
to, or could result in any of the matters referred to in Paragraphs (b) through
(j) of Item 4 of Schedule 13D.

Item 5.  Interest in Securities of the Issuer.

      (a)-(b) According to the Company there were 25,944,844 outstanding shares
of Common Stock on June 28, 2002 after giving effect to the 10,400,000 shares of
Common Stock issued in connection with the Merger. Immediately after the
consummation of the Merger, the Reporting Person beneficially owned 5,334,863
shares of Common Stock, which amount included (i) 5,184,863 shares owned
directly by the Reporting Person, (ii) 10,000 shares issuable upon exercise of
options owned by the Reporting Person, (iii) 100,000 shares issuable upon
conversion of the Note and (iv) 40,000 shares beneficially owned by Kit Howard,
the wife of the Reporting Person, (of which 25,000 shares are issuable upon
exercise of options owned by the wife of the Reporting Person). The Reporting
Person may be deemed to have sole voting and disposition power over the shares
referred to in items (i) - (iii) above and shared voting and disposition power
over the shares referred to in item (iv) above.

      (c) During the past 60 days the Reporting Person (i) in connection with
the Merger acquired beneficial ownership of 2,000,000 shares of Common Stock in
exchange for the 1,600,000 shares of Common Stock of ISSI


                                  3 of 5 Pages


owned by RH immediately prior to the Merger and (ii) the Note was issued by the
Company in favor of the Reporting Person in consideration of a loan in the
principal amount of $250,000 made by the Reporting Person to the Company. The
Note is convertible into 100,000 shares of Common Stock at $2.50 per share.

      (d) Kit Howard, the Reporting Person's spouse, has the right to receive
dividends on, and any proceeds from the disposition of any shares of Common
Stock reported as owned by her in Item 5 above.

      (e) It is inapplicable for the purposes hereof to state the date on which
the Reporting Person ceased to be the owner of more than five percent (5%) of
the Common Stock.

Item  6. Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

      The Company has a Convertible Revolving Credit Promissory Note and
Revolving Loan and Security Agreement (the "Loan Agreement") with the Reporting
Person under which the Reporting Person has agreed to advance funds, or to
provide guarantees of advances made by third parties in an amount up to
$3,000,000. The Loan Agreement expires January 4, 2004, subject to extension by
the parties. Outstanding advances are collateralized by substantially all of the
assets of the Company and bear interest at prime interest rate plus 2%. The Loan
Agreement entitles the Reporting Person to convert outstanding advances into
shares of Common Stock at any time based on the lesser of the market price of
the Common Stock at the time of the advance or at the time of conversion of the
Note.

      In connection with the Merger, the Company entered into a stockholders'
agreement with the Reporting Person, the Company's Chief Executive Officer and
certain stockholders of ISSI. The parties to the stockholders' agreement agreed
to limit the number of shares of the Company's Common Stock each may sell on a
quarterly basis over the course of two years from the consummation of the
Merger.

      Except as described in this Item 6 and in Item 5 above, there are no
contracts, arrangements, understandings or relationships with the Reporting
Person or any other person with respect to the securities of the Company,
including but not limited to transfer or voting of any other securities,
finders' fees, joint ventures, loan or option arrangements, puts or calls,
guaranties of profits, divisions of profits or loss or the giving or withholding
of proxies.
