Item 5. Other Events.

On June 26, 1997, Lawter International, Inc. ("Lawter") and Hach Company
("Hach") entered into a Purchase and Standstill Agreement and Mutual Release
(the "Agreement") pursuant to which Lawter agreed to sell all of its 3,157,220
shares of Hach Common Stock (the "Lawter Shares"), which constitute
approximately 27.8% of the issued and outstanding shares of Common Stock of
Hach, and Hach agreed to purchase the Lawter Shares, for a purchase price of $19
per share or a total of $59,987,180 for all of the Lawter Shares (the "Purchase
Price").  The closing of the transaction is scheduled to take place on or prior
to July 8, 1997 (the "Closing Date"), subject to certain customary closing
conditions.  A copy of the Agreement is set forth as Exhibit 99.2 to this Report
and is incorporated herein by this reference.
The Agreement provides that, for a period of ten years, Lawter shall be subject
to certain standstill provisions relating to Hach.  Such provisions include, but
are not limited to, Lawter's agreement not to (a) acquire, directly or
indirectly, any beneficial ownership of any common stock or other securities of
Hach; (b) participate in any "solicitation" of "proxies" as defined in Rule 14a-
1 of the Exchange Act of 1934; (c) make any statement or proposal with respect
to a merger, sale or transfer of assets, recapitalization or other extraordinary
corporate transaction with regard to Hach; or (d) seek to exercise control over
Hach.
The Agreement allows for an adjustment to the Purchase Price in the event there
is a Change of Control of Hach (as defined in the Agreement) on or prior to
September 30, 1998 and as a result of such Change of Control any stockholder of
Hach receives cash of more than $19 per share for their Common Stock of Hach.
At the closing of any such transaction, Hach will pay to Lawter in cash an
amount equal to (x) the difference between the greatest amount per share
received by the stockholders of Hach in such transaction and the amount of the
Purchase Price paid per share for the Lawter Shares pursuant to the Agreement
times (y) 3,157,220.
