          -------------

Hahn, Shipp and Hawkins are all directors and officers of the Issuer and Mr. 
Dee is an officer but not a director. Apart from the plan holdings in this 
plan and the individual interests of each trustee under such plan as of 
December 31, 1999, these individuals had personal holdings of the Issuer's 
common stock as set forth below. Unless otherwise noted, all shares shown are 
held by individuals possessing sole voting and dispositive power with respect 
to such shares.

     (b)  The Hawkins Chemical, Inc. Employee Stock Ownership Plan and Trust
(the "ESOP") currently holds 2,434,823 shares of the Issuer's common stock,
representing 22% of the total outstanding shares. The ESOP allows participants
to direct the voting of shares allocated to their accounts, but since the
Trustees may vote shares with respect to which no directions are received, the
Trustees may be deemed to share voting power as to all of these shares. In
addition, certain Trustees, as individual participants in the ESOP, have the
power to direct the voting of the following number of shares allocated to their
personal accounts as of December 31, 1999: Dean L. Hahn, 205,301 shares; Donald
L. Shipp, 181,654 shares; and John R. Hawkins, 122,090 shares. The Trustees also
have dispositive power with respect to all 2,434,823 shares, provided that this
power is limited by a requirement that the assets of the ESOP Trust must consist
primarily of shares of the Issuer's stock. Each Trustee disclaims beneficial
ownership of the shares attributed to him solely as a Trustee of the ESOP.



---------------------
(1)  Mr. Hahn has sole voting and dispositive power over all of these 106,576
shares, except for 9,902 shares that Mr. Hahn holds jointly with his wife as to
which he shares voting and dispositive power.

(2)  Mr. Shipp has sole voting and dispositive power over all of these 122,171
shares, except 60,000 shares held by his wife as to which he may be deemed to
share voting and investment power, but as to which he disclaims beneficial
ownership.

(3)  Mr. Hawkins has sole voting and dispositive power over all of these 75,787
shares, except 42,647 shares held by him as custodian for one minor child as to
which he has full voting and dispositive power, but as to which he disclaims
beneficial ownership; and 33,080 shares that Mr. Hawkins holds jointly with his
wife as to which he shares voting and dispositive power.
