                   PROMISSORY NOTE AND REDEMPTION AGREEMENT

Principal:  $5,000,000                             Date: April 28, 1999

1.   Promise to Pay. For value received, Myron W. Wentz ("Borrower"), promises
                                                          --------
     to pay to the order of USANA, Inc. ("Holder") at 3838 West Parkway Blvd.,
                                          ------
     Salt Lake City, Utah or such other place as the Holder hereof from time to
     time may designate in writing, the principal sum of up to FIVE MILLION
     DOLLARS ($5,000,000), plus interest and such other sums as are payable
     under the terms of this Note.

2.   Payments. All unpaid principal, interest and other sums owing under this
     Note shall be due and payable as follows: (a) $2,500,000 on or before
     August 31, 1999; and (b) the balance of principal and accrued interest on
     or before December 31, 1999 (each of August 31, 1999 and December 31, 1999,
     a "Due Date"). Borrower may completely or partially prepay this Note at any
        --- ----
     time or from time to time without penalty. Payments shall be applied first
     to accrued interest, costs and expenses payable under this Note and then to
     principal.

3.   Interest. Interest shall accrue on the unpaid principal balance from and
     after the date hereof at "Prime Rate" as that term is defined in Holder's
                               ----- ----
     bank line of credit agreement until this Note is paid in full. At the date
     of this Note, the Prime Rate is 7.75% per annum. Upon occurrence of an
     Event of Default under that certain Stock Pledge Agreement of even date
     herewith ("Stock Pledge Agreement") executed by Gull Holdings Ltd.
                ----------------------
     ("Gull"), which prevents the delivery of securities having a Market Value
       ----
     sufficient to make payment in full of any installment or amount when due
     hereunder, the unpaid balance of principal then due will bear interest at
     the rate of Prime Rate plus 5% until payment of such delinquent amount is
     made in full.

4.   Method of Payment; Default. Unless prepayment is made by Borrower, amounts
     due and owing hereunder will be paid by the immediate and automatic
     redemption on each Due Date of shares of common stock of USANA, Inc.
     ("Shares") beneficially owned by Borrower in the name of Gull having a
       ------
     Market Value (as defined below) equal to the principal and interest then
     owing on such Due Date(s). For purposes of this Note and the Stock Pledge
     Agreement, the Market Value of Shares surrendered or cancelled in payment
     of amounts owing hereunder will be determined by the average closing price
     of USANA, Inc. common stock as reported by the Nasdaq Stock Market for the
     five trading days preceding the date payment is made. Payment will be made
     from the Shares pledged by Gull pursuant to the Stock Pledge Agreement.
     Borrower's failure to surrender or cause the surrender of such Shares as
     may be required to make a payment when due will not prevent Holder from
     instructing its transfer agent to cancel Shares having the Market Value of
     the payment then due. Holder may instruct its transfer agent to stop
     transfer of Shares held by Gull or to cancel such Shares as may be
     necessary to make the payments required hereunder. Borrower consents to
     such action by Holder and waives any objection or right to notice of such
     action. No additional instruction to the transfer agent will be necessary
     other than a copy of this Note and the Holder's notice that payment is due
     and the Shares have not been surrendered as contemplated hereunder.

 
5.   Prepayment. Borrower may make interim payments prior to the Due Dates in
     cash or by surrendering Shares or instructing USANA to cancel Shares
     pledged by Gull as provided herein. However, not more than two (2) interim
     payments by the surrender of Shares may be made from the date hereof
     through August 31, 1999, and not more than two (2) such payments may be
     made from September 1, 1999 through December 31, 1999.

6.   Attorneys' Fees and Costs. If any action, judicial or nonjudicial, is
     brought on this Note, or if it is placed in the hands of an attorney for
     collection, Borrower promises to pay all of Holder's costs and expenses in
     connection therewith, including without limitation the reasonable
     attorneys' fees incurred and paid by holder in connection herewith through
     any appeal or in bankruptcy.

7.   Waivers. The undersigned, all endorsers, and all persons liable or to
     become liable on this Note hereby waive presentment, demand, protest and
     notice of demand, protest and nonpayment, and any defense or claim that
     resort must first be had to any security or to any other person, and
     authorize the holder of this Note, without affecting his, her or its
     liability hereunder, from time to time, to renew, extend, or change the
     time for payment or the other terms of this Note, to take and hold security
     for the payment of this Note, to release or exchange the security therefor,
     to apply any such security to such obligations as the holder may determine
     in its sole discretion, and to release, substitute, or add to those liable
     or to become liable on this Note.

8.   Governing Law. This Note shall be governed by and construed in accordance
     with the laws of the State of Utah, United States of America, without
     regard for conflict of law rules, and the parties consent and stipulate to
     the jurisdiction and venue in all appropriate courts located in Salt Lake
     County, Utah.

                                        BORROWER:
