have agreed pursuant to Rule 13d-1(k) under the Securities Exchange Act of 1934,
as amended, to file one Statement on Schedule 13D with respect to their
ownership of Common Stock. Capitalized terms used herein and not defined herein
have the meanings ascribed thereto in the Schedule 13D, as previously amended.
ITEM 2. IDENTITY AND BACKGROUND
Item 2 is hereby amended and supplemented as follows:
The Reporting Persons are filing this Schedule 13D jointly, pursuant to
the Joint Filing Agreement, dated July 15, 2003, filed as an exhibit hereto.
ITEM 4. PURPOSE OF TRANSACTION
Item 4 is hereby amended and supplemented as follows:
On July 14, 2003, ISP issued a press release (the "Press Release")
announcing that it intends, either directly or through an affiliate, upon the
election to the Hercules Board of Directors of the nominees of The Hercules
Shareholders' Committee for NEW Management (the "Committee"), to acquire an
additional ten million shares of Common Stock. ISP or its affiliate intends to
commence a tender offer for five million shares of Common Stock at $12.00 per
share in cash and to purchase an additional five million shares of Hercules
common stock through open market purchases thereafter.
In a letter from ISP and Mr. Heyman to the Committee dated July 14,
2003 (the "Commitment Letter"), ISP and Mr. Heyman committed to enter into a
standstill agreement, which would become effective upon the election to the
Hercules Board of Directors of all four of the Nominees. Pursuant to the
standstill agreement, ISP and Mr. Heyman would agree, for a period of two years,
not to make any acquisition or merger proposal for Hercules or any of its
business units, unless a third party makes an acquisition proposal first, and to
otherwise limit their ownership in Hercules' stock to 20% of Hercules'
outstanding shares.
Page 13 of 17 Pages
The foregoing summary of the Press Release and the Commitment Letter
are qualified in their entirety by reference to the text of the documents, which
are attached hereto as Exhibits 99.01 and 99.02, respectively, and which are
incorporated herein by reference.
The commitments set forth in the Commitment Letter are in addition
to the procedural safeguards set forth in the June 24th letter from ISP and Mr.
Heyman to the Committee, which is attached hereto as Exhibit 99.03 and which is
incorporated herein by reference.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
Item 5 is hereby amended and supplemented as follows:
Each of ISP, the Minority Directors and Nominees have agreed to be part
of the Committee. Because of such agreement, ISP, the Minority Directors and
Nominees may be deemed to be part of a "group" for purposes of Rule 13d-3 of the
Exchange Act. Investco, Holdings, ISP and Mr. Heyman may also be deemed to part
of the "group" because: (i) as of the filing of this Amendment No. 15 Investco
has the sole power to vote, direct the voting of, dispose of and direct the
disposition of 9,893,700 shares of Common Stock (the "Investco Shares"); (ii)
Holdings, by virtue of being the sole member of Investco, may be deemed to own
beneficially (solely for purposes of Rule 13d-3 under the Exchange Act) the
Investco Shares; (iii) ISP, by virtue of its ownership of all of the outstanding
common stock of Holdings, may be deemed to own beneficially (solely for purposes
of Rule 13d-3 under the Exchange Act) the Investco Shares and (iv) Mr. Heyman,
by virtue of his deemed beneficial ownership (as defined in Rule 13d-3 under the
