ITEM 4.       CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

              On June 20, 2002, the Board of Directors of ISP Chemco Inc.
("Chemco"), decided not to renew the engagement of its independent auditors,
Arthur Andersen LLP ("Arthur Andersen"), and selected KPMG LLP as its
independent auditors for the fiscal year ending December 31, 2002. The change in
auditors will become effective June 21, 2002.

              Arthur Andersen's reports on the consolidated financial statements
of Chemco for the fiscal years ended December 31, 2001 and 2000 did not contain
any adverse opinion or disclaimer of opinion, nor were they qualified or
modified as to uncertainty, audit scope, or accounting principles.

              During the fiscal years ended December 31, 2001 and 2000 and the
subsequent interim period between December 31, 2001 and the date of this Current
Report on Form 8-K, there were no disagreements between Chemco and Arthur
Andersen on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which, if not resolved to
Arthur Andersen's satisfaction, would have caused Arthur Andersen to make
reference to the subject matter of the disagreement in connection with its
reports for such years; and there were no reportable events as defined in Item
304(a)(1)(v) of Regulation S-K.

              Chemco has provided to Arthur Andersen a copy of the foregoing
disclosures made in this Current Report on Form 8-K. Attached as Exhibit 16 is a
copy of Arthur Andersen's letter, dated June 21, 2002, stating it has found no
basis for disagreement with such statements.

              During the fiscal years ended December 31, 2001 and 2000 and the
subsequent interim period between December 31, 2001 and the date of this Current
Report on Form 8-K, neither Chemco nor anyone acting on its behalf consulted
with KPMG LLP with respect to the application of accounting principles to a
specified transaction, either completed or proposed, or the type of audit
opinion that might be rendered on Chemco's consolidated financial statements, or
any other matters or reportable events listed in Items 304(a)(2)(i) and (ii) of
Regulation S-K.
