ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. 

     The net investment cost (including commissions, if any) of the shares of
Common Stock beneficially owned by EGS Associates, EGS Partners, Bev Partners 
and Pharm Fund is approximately $1,209,682, $2,988,495, $708,164 and 
$1,025,999, respectively.

      To the best of Mr. Greenberg's knowledge, the net investment cost

$143,261.

      The net investment cost (including commissions, if any) of the shares of
Common Stock owned directly by Mr. Ketcher, is approximately $129,197.

      The shares of Common Stock purchased by each of EGS Associates, Bev

Partners were purchased with investment capital of discretionary accounts 
under management of EGS Partners.  The shares of Common Stock purchased by 
Messrs. Greenberg (and members of his immediate family) and Ketcher were
purchased with personal funds or trust funds.

Partners, Bev Partners, and Pharm Fund are held in their respective commingled 
margin accounts, or in the case of EGS Partners, in margin and non-margin 
accounts held by discretionary accounts under its management.  Such margin 
accounts are maintained at Bear Stearns & Co. Inc., and may from time to time 
have debit balances.  Non-margin accounts are maintained at Bankers Trust

possible to determine the amounts, if any, of margin used with respect to the 
shares of Common Stock purchased.  The shares owned by Mr. Greenberg are held 
in his various accounts maintained at Goldman, Sachs & Co. or are beneficially 
owned by members of his immediate family.  The shares owned by Mr. Ketcher are 
held in his various accounts maintained at First Boston Corporation.  
Currently, the interest rate charged on such various margin accounts is 
approximately 7% per annum.

ITEM 4.   PURPOSE OF THE TRANSACTION.

      The purpose of the acquisition of the shares of the Common Stock by the
Reporting Persons was for investment.  The Reporting Persons may in the future 
dispose of any or all of the shares of the Common Stock held by it or him at 
any time, or acquire other shares.

      Except as set forth in the preceding paragraph, none of the Reporting

of the matters referred to in paragraphs (b) through (j), inclusive, of 
Item 4 of Schedule 13D.  Such entities and persons may, at any time and from
time to time, review or reconsider their position with respect to the Company,
and formulate plans or proposals with respect to any of such matters.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER. 

      (a)  The approximate aggregate percentage of shares of Common Stock
reported beneficially owned by each person herein is based on 10,526,932
shares outstanding, which is the total number of shares of Common Stock
outstanding as of April 24, 1997, as reflected in the company's quarterly 
report on Form 10-Q filed with the Securities and Exchange Commission (the
"Commission") for the fiscal quarter ended March 31, 1997 (which is the most
recent Form 10-Q on file).

      As of the close of business on July 2, 1997:

           (i)   EGS Associates owns beneficially 100,683 shares of Common
Stock, constituting approximately 1.0% of the shares outstanding.

           (ii)  EGS Partners owns directly no shares of Common Stock.  By
reason of the provisions of Rule 13d-3 of the Securities Exchange Act of 1934,
as amended (the "Act"), EGS Partners may be deemed to own beneficially 275,286
shares, constituting approximately 2.6% of the shares outstanding, purchased
for discretionary accounts managed by it.

           (iii) Bev Partners owns beneficially 48,831 shares of Common
Stock, constituting approximately 0.5% of the shares outstanding.

           (iv)  Pharm Fund owns 87,346 shares of Common Stock, constituting

    13D                                                    Page 14 of 22 Pages

           (v)   Mr. Greenberg owns directly, and beneficially through
ownership by members of his immediate family, 10,400 shares of Common Stock,
constituting approximately 0.1% of the shares outstanding.

           (vi)  Mr. Ketcher owns directly 12,100 shares of Common Stock,
constituting approximately 0.1% of the shares outstanding.

           (vii) Messrs. Ehrman, Gerstl and McLaren own directly no shares of 
Common Stock.

           By reason of the provisions of Rule 13d-3 of the Act, each of the
General Partners may be deemed to own the 100,683 shares beneficially owned by
EGS Associates, the 275,286 shares beneficially owned by EGS Partners, the
48,831 shares beneficially owned by Bev Partners and the 87,346 shares
beneficially owned by Pharm Fund.  When the shares beneficially owned by EGS
Associates, EGS Partners, Bev Partners, and Pharm Fund are aggregated, they
total 512,146 shares of Common Stock, constituting approximately 4.9% of the
shares outstanding.

           (viii)      In the aggregate, the Reporting Persons beneficially
own a total of 534,646 shares of Common Stock, constituting approximately
5.1% of the shares outstanding.

           (b)   (i)   Each of EGS Associates, EGS Partners (with respect to
shares of the discretionary accounts), Bev Partners and Pharm Fund has the 
power to vote and to dispose of the shares of Common Stock beneficially 
owned by it, which power may be exercised by the General Partners, except
that there is no voting power over 1,620 shares of Common Stock held in one 
of the discretionary accounts.  Each of the discretionary accounts is a 
party to an investment management agreement with EGS Partners pursuant to 
which EGS Partners has investment authority with respect to securities held 
in such account.

                 (ii)  Each General Partner has the sole power to vote and
dispose of the shares owned directly by him.  Mr. Greenberg has shared power
to vote and dispose of shares owned by members of his immediate family.

           (c)   The trading dates, number of shares of Common Stock
purchased or sold and price per share for all transactions in the Common 
Stock from the 60th day prior to July 2, 1997 up to and including July 
2, 1997 by EGS Associates, EGS Partners, Pharm Fund, Bev Partners, and Mr. 
Ketcher, are set forth in Schedules A, B, C, D and E.  During such period,

the power to direct the receipt of dividends from or the proceeds of sale of
such shares of Common Stock.
