RESTRICTED STOCK PURCHASE AGREEMENT

     THIS RESTRICTED STOCK PURCHASE AGREEMENT ("Agreement") is entered into as
of March 6, 2000, by Wild Oats Markets, Inc., a Delaware corporation (the
"Company"), and Perry D. Odak (the "Purchaser").

SECTION A -- Acquisition Of Shares


1.   Transfer. Pursuant to the employment agreement between the parties dated as
     of March 6, 2001 ("Employment Agreement"), and subject to the terms and
     conditions set forth in this Agreement, the Company agrees to transfer
     1,332,649 shares ("Purchased Shares") of Common Stock, $0.001 par value per
     share, of the Company ("Stock") to the Purchaser. The transfer shall occur
     at the offices of the Company on the date set forth above or at such other
     place and time as the parties may agree.

2.   Consideration. The Purchaser agrees to pay $6.969 for each Purchased Share
     ("Purchase Price"), or an aggregate of $9,287,230.15. The Purchase Price is
     agreed to be at 100% of the per share closing price of the Stock on NASDAQ
     as of the date of purchase. Payment of $0.01 per share shall be made on the
     purchase date in cash or cash equivalents and the balance shall be paid by
     delivery of a full recourse, five-year promissory note in an original
     principal amount equal to the amount of the Purchase Price for the
     Purchased Shares not otherwise paid in cash or cash equivalents (the
     "Note") (the form of which is attached hereto as Exhibit A and made a part
     hereof), with interest on the Note at the rate set forth in the Note.
     Payments of principal and interest due under the Note shall be subject to
     acceleration under the terms set forth therein and in the Pledge Agreement.
     The Note shall provide for a balloon payment of principal and accrued,
     unpaid interest on the fifth anniversary of the date the Note is made.

3.   Tax Election and Withholding. Purchaser hereby acknowledges that he has
     been advised by the Company to seek independent tax advice regarding the
     availability and advisability of making an election under Section 83(b) of
     the Internal Revenue Code of 1986, as amended (the "Code"), and that any
     such election (an "83(b) Election"), if made, must be made within 30 days
     of the date the Purchased Shares are transferred to the Purchaser. At the
     time of making a timely 83(b) Election, or, in the event the Purchaser
     fails to make a timely 83(b) Election, on each date on which a Right of
     Repurchase (defined below) lapses, the Company shall have the right to
     deduct from any compensation or any other payment of any kind (including
     withholding the release of Purchased Shares) due the Purchaser the amount
     of any federal, state or local taxes required by law to be withheld as a
     result of the purchase of the Purchased Shares or the lapse of the Right of
     Repurchase in whole or in part; provided, however, that the value of
     Purchased Shares withheld may not exceed the statutory minimum withholding
     amount required by law. In lieu of such deduction, the Company may require
     the Purchaser to make a cash payment to the Company equal to the amount
     required to be withheld. If the Purchaser does not make such payment when
     requested, the Company may refuse to release any certificate representing
     Purchased Shares under this Agreement until arrangements satisfactory to
     the Board of Directors of the Company for such payment have been made.

SECTION B -- Right Of Repurchase

1.   Scope of Repurchase Right. All Purchased Shares initially shall be
     "Restricted Shares" and shall be subject to a right, but not an obligation,
     of repurchase by the Company ("Right of Repurchase"). The Purchaser shall
     not transfer, assign, encumber, sell, hypothecate, exchange or otherwise
     dispose of any Restricted Shares, except by will or the laws of descent and
     distribution, subject to the terms of this Agreement.

2.   Condition Precedent to Exercise of Repurchase Right. Subject to Paragraph 3
     below, the Right of Repurchase shall be exercisable with respect to any or
     all of the Restricted Shares at any time (i) following the date when the
     Purchaser's employment pursuant to the Employment Agreement terminates for
     any reason, with or without cause, including death or disability, or (ii)
     if the Purchaser does not commence employment on the effective date of the
     Employment Agreement.

3.   Lapse of Repurchase Right. Provided that the Purchaser has remained in the
     continuous employment of the Company pursuant to the Employment Agreement
     from the effective date of that agreement, the Right of Repurchase shall
     lapse and the Purchased Shares shall no longer be Restricted Shares (i.e.,
     they shall become "vested") as follows:

     (i) Unless vesting is accelerated pursuant to clauses (ii) or (iii) below,
     on each of the dates specified in the following table with respect to the
     aggregate percentage of Purchased Shares indicated:

</TABLE>

     The extent to which the Purchased Shares are vested as of a particular
     vesting date specified above, determined based on the total number of
     Purchased Shares, is rounded down to the nearest whole share. However,
     vesting is rounded up to the nearest whole share with respect to the last
     vesting date reflected on this vesting schedule.

     (ii) The aggregate percentage of Purchased Shares specified below shall
     become vested when the fair market value of the Stock, as measured by the
     average of the daily closing stock prices on NASDAQ for the preceding 90
     consecutive trading days, shall equal at least the corresponding Per Share
     Fair Market Value Threshold indicated (such shares being the Restricted
     Shares that would regularly vest the latest under clause (i) above
     following the date when such acceleration under this clause (ii) has become
     effective):

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

     For example, if 25% of the Purchased Shares are already vested pursuant to
     clause (i) above, and 50% of the Purchased Shares become vested pursuant to
     this clause (ii), then the Purchaser shall be vested in 75% of the
     Purchased Shares.

     (iii) One hundred percent (100%) of the Restricted Shares shall become
     vested upon a Change in Control of the Company (as defined in the
     Employment Agreement), within the first twelve months after the effective
     date of the Employment Agreement, or upon a Change of Control of the
     Company thereafter if the fair market value of the Stock, as measured by
     the closing stock price on NASDAQ immediately prior to the Change in
     Control, shall equal at least Twenty Dollars ($20).

4.   Repurchase Cost. If the Company exercises the Right of Repurchase, it shall
     pay the Purchaser an amount equal to the Purchase Price for each of the
     Restricted Shares being repurchased.

5.   Exercise of Repurchase Right. The Right of Repurchase shall be exercisable
     only by written notice delivered to the Purchaser. The notice shall set
     forth the date on which the repurchase is to be effected. Such date shall
     not be more than 30 days after the date of the notice. To the extent not
     held in escrow by the Company, the certificate(s) representing the
     Restricted Shares to be repurchased shall, prior to the close of business
     on the date specified for the repurchase, be delivered to the Company
     properly endorsed for transfer, together with any other documents needed to
     effectuate the transfer. The Company shall, concurrently with the receipt
     of such certificate(s), pay to the Purchaser the purchase price determined
     according to Paragraph B.4 above. Payment shall be made (a) in cash or cash
     equivalents, (b) by canceling indebtedness to the Company, including
     indebtedness incurred by the Purchaser in the purchase of the Restricted
     Shares (whether or not then due), or (c) by a combination of the foregoing.

6.   Additional Shares or Substituted Securities. In the event of a stock
     dividend, extraordinary dividend payable in a form other than stock,
     spin-off, stock split, reverse stock split, recapitalization, or similar
     transaction affecting the Company's outstanding securities that is effected
     without receipt of consideration, any new, substituted or additional
     securities or other property (including money paid other than as an
     ordinary cash dividend) that are by reason of such transaction distributed
     with respect to any Restricted Shares shall immediately be subject to this
     Agreement (including the Right of Repurchase). Appropriate adjustments to
     reflect the distribution of such securities or property shall be made to
     the number and/or class of the Restricted Shares. Appropriate adjustments
     shall also be made, after each such transaction, to the per share fair
     market value prices referred to in Paragraph B.3(ii) above, and the price
     per share to be paid upon the exercise of the Right of Repurchase, in order
     to reflect any change in the Company's outstanding securities effected
     without receipt of consideration therefor; provided, however, that the
     aggregate purchase price payable for the Restricted Shares shall remain the
     same.

7.   Termination of Rights as Stockholder. If the Company makes available, at
     the time and place and in the amount and form provided in this Agreement,
     the consideration for the Restricted Shares to be repurchased in accordance
     with this Section B, then after such time the person from whom such
     Restricted Shares are to be repurchased shall no longer have any rights as
     a holder of such Restricted Shares (other than the right to receive payment
     of such consideration in accordance with this Agreement). Such Restricted
     Shares shall be deemed to have been repurchased in accordance with the
     applicable provisions hereof, whether or not the certificate(s) therefor
     have been delivered as required by this Agreement.

8.   Escrow Upon issuance, the certificates for Restricted Shares shall be
     deposited in escrow with the Company, together with a stock power, endorsed
     in blank by the Purchaser, with respect to the Restricted Shares, to be
     held in accordance with the provisions of this Agreement. Any new,
     substituted or additional securities or other property described in
     Paragraph B.6 above shall immediately be delivered to the Company to be
     held in escrow, but only to the extent the Purchased Shares with respect to
     which such securities or other property are issued are, at the time,
     Restricted Shares. All regular cash dividends on Restricted Shares (or
     other securities at the time held in escrow) shall be paid directly to the
     Purchaser and shall not be held in escrow. The Purchaser shall have no
     right to vote the Restricted Shares while held in escrow. Restricted
     Shares, together with any other assets or securities held in escrow
     hereunder, shall be (i) surrendered to the Company for repurchase and
     cancellation upon the Company's exercise of its Right of Repurchase
     (provided that the Purchaser hereby appoints the Company as
     attorney-in-fact to execute any repurchase agreement and related
     certificates and documents for the repurchase of the Restricted Shares by
     the Company and to endorse and transfer such shares to the Company) or (ii)
     released to the Purchaser upon the Purchaser's request to the extent the
     Purchased Shares are no longer Restricted Shares. In any event, all
     Purchased Shares which have vested (and any other vested assets and
     securities attributable thereto) shall be released within 60 days after the
     Purchaser's cessation of employment pursuant to the Employment Agreement.

SECTION C -- Restrictions On Transfer

1.   Purchaser Representations. In connection with the issuance and acquisition
     of Purchased Shares under this Agreement, the Purchaser hereby represents
     and warrants to the Company as follows:

     The Purchaser understands and is familiar with the requirements of
     Regulation D (17 C.F.R. ss.230.501-08), and is an accredited investor
     within the meaning of the Securities Act of 1933 (the "Securities Act").

     The Purchaser is acquiring and will hold the Purchased Shares for
     investment for his account only and not with a view to, or for resale in
     connection with, any "distribution" thereof within the meaning of the
     Securities Act.

     The Purchaser understands that the Purchased Shares have not been
     registered under the Securities Act by reason of a specific exemption
     therefrom and that the Purchased Shares must be held indefinitely, unless
     they are subsequently registered under the Securities Act or the Purchaser
     obtains an opinion of counsel, in form and substance satisfactory to the
     Company and its counsel, that such registration is not required. The
     Purchaser further acknowledges and understands that the Company is under no
     obligation to register the Purchased Shares.

     The Purchaser is aware of the adoption of Rule 144 by the Securities and
     Exchange Commission under the Securities Act, which permits limited public
     resales of securities acquired in a non-public offering, subject to the
     satisfaction of certain conditions, including without limitation the
     availability of certain current public information about the issuer, the
     resale occurring only after the holding period required by Rule 144 has
     been satisfied, the sale occurring through an unsolicited "broker's
     transaction," and the amount of securities being sold during any
     three-month period not exceeding specified limitations.

     The Purchaser will not sell, transfer or otherwise dispose of the Purchased
     Shares in violation of the Securities Act, the Securities Exchange Act of
     1934, or the rules promulgated thereunder, including Rule 144 under the
     Securities Act. The Purchaser agrees that he will not dispose of the
     Purchased Shares unless and until he has complied with all requirements of
     this Agreement applicable to the disposition of Purchased Shares and he has
     provided the Company with written assurances, in substance and form
     satisfactory to the Company, that (a) the proposed disposition does not
     require registration of the Purchased Shares under the Securities Act or
     all appropriate action necessary for compliance with the registration
     requirements of the Securities Act or with any exemption from registration
     available under the Securities Act (including Rule 144) has been taken and
     (b) the proposed disposition will not result in the contravention of any
     transfer restrictions applicable to the Purchased Shares under state
     securities law.

     The Purchaser has been furnished with, and has had access to, such
     information as he considers necessary or appropriate for deciding whether
     to invest in the Purchased Shares, and the Purchaser has had an opportunity
     to ask questions and receive answers from the Company regarding the terms
     and conditions of the issuance of the Purchased Shares.

     The Purchaser is aware that his investment in the Company is a speculative
     investment which has limited liquidity and is subject to the risk of
     complete loss. The Purchaser is able, without impairing his financial
     condition, to hold the Purchased Shares for an indefinite period and to
     suffer a complete loss of his investment in the Purchased Shares.

2.   Securities Law Restrictions. Regardless of whether the offering and sale of
     Shares under this Agreement have been registered under the Securities Act
     or have been registered or qualified under the securities laws of any
     state, the Company at its discretion may impose restrictions upon the sale,
     pledge or other transfer of the Purchased Shares (including the placement
     of appropriate legends on stock certificates or the imposition of
     stop-transfer instructions) if, in the judgment of the Company, such
     restrictions are necessary or desirable in order to achieve compliance with
     the Securities Act, the securities laws of any state or any other law.

3.   Rights of the Company. The Company shall not be required to (i) transfer on
     its books any Purchased Shares that have been sold or transferred in
     contravention of this Agreement or (ii) treat as the owner of Purchased
     Shares, or otherwise to accord voting, dividend or liquidation rights to,
     any transferee to whom Purchased Shares have been transferred in
     contravention of this Agreement.

4.   Piggyback Registration Rights. If the Company proposes to register any of
     its equity securities under the Securities Act (other than a registration
     effected solely to implement an employee benefit plan or transaction to
     which Rule 145 of the Securities Act is applicable, or a registration using
     any form that does not permit secondary sales of securities), on a form and
     in a manner that would permit registration of the Purchased Shares for sale
     to the public under the Securities Act, it will give written notice to the
     Purchaser of its intention to do so, describing such securities and
     specifying the form and manner and other relevant facts involved in such
     proposed registration, if such disclosure is acceptable to the managing
     underwriter. Upon the written request of the Purchaser delivered to the
     Company within ten (10) days after the receipt of any such notice (which
     request shall specify the Purchased Shares intended to be disposed of by
     the Purchaser and the intended method of disposition thereof), the Company
     will use reasonable commercial efforts (at the Company's expense, other
     than underwriting commissions, stock transfer taxes and opinions of counsel
     accruing to or required by the Purchased Shares being registered) to effect
     the registration under the Securities Act of all the Purchased Shares that
     the Company has been so requested to register; provided, however, that:

     (i) The Company shall only be obligated to register those Purchased Shares
     which are fully paid and nonassessable, which have fully vested under any
     vesting schedule applicable to Purchased Shares, and with respect to which
     any indebtedness incurred by the Purchaser in the purchase of the Purchased
     Shares has been paid.

     (ii) If, at any time after giving such written notice of its intention to
     register its securities and prior to the effective date of the registration
     statement filed in connection with such registration, the Company shall
     determine for any reason not to register such securities, the Company may,
     at its election, give notice of such determination to the Purchaser and
     thereupon the Company shall be relieved of its obligation to register any
     Purchased Shares in connection with such registration.

     (iii) If such registration involves an underwritten offering, the Purchaser
     must sell the Purchased Shares requested to be registered to the
     underwriter selected by the Company on the same terms and conditions as
     apply to the Company or the other selling stockholders participating
     therein, and Purchaser shall bear all costs of such sale.

     The Company shall not be obligated to effect any registration of Purchased
     Shares incidental to the registration of any of its securities in
     connection with mergers, acquisitions, exchange offers, dividend
     reinvestment plans or stock option or other employee benefit plans. If a
     registration pursuant to this Agreement involves an underwritten offering
     and the sole or managing underwriter advises the Company that, in its
     opinion, the number of securities proposed to be included in such
     registration should be limited due to market conditions or the necessity of
     including shares being sold by the Company, or being sold by third parties
     pursuant to the Registration Rights Agreement dated July 12, 1996, then the
     Company will notify the Purchaser, if he has requested registration, and
     the Purchased Shares shall be excluded until such limitation has been met.
     The Company shall have the right to select the managing underwriter with
     respect to any offering. The Company shall have no obligation to pro rate
     the amount of Purchased Shares that the Purchaser may register in any such
     offering, in the event the number of shares includable is limited.

     Notwithstanding the foregoing, the Company shall not be required to
     included any Purchased Shares in any registration in the event that the

                                 PROMISSORY NOTE


$ 9,273,978.31                                                     March 6, 2001
                                                               Boulder, Colorado


                FOR VALUE RECEIVED, Perry D. Odak ("Borrower") promises to pay
to the order of Wild Oats Markets, Inc., a Delaware corporation ("Holder"), the
principal sum of Nine Million Two Hundred Seventy Three Thousand Nine Hundred
Seventy Eight and 31/100 Dollars ($9,273,978.31) ("Principal Sum"), together
with interest computed on the unpaid balance of the Principal Sum calculated
from the date hereof until paid in full in accordance with the provisions of
this Note (the "Loan").

         Borrower has delivered to Holder on the date hereof an executed
Restricted Stock Purchase Agreement (the "Stock Purchase Agreement"), pursuant
to which Borrower purchased 1,332,649 shares of Common Stock, par value of
$0.001 per share, of Wild Oats Markets, Inc. (the "Shares"). Borrower has paid
$13,251.84 in cash and has requested that Holder make the Loan to Borrower to
pay the balance of the purchase price of the Shares, and Holder is willing to
make the Loan to Borrower upon the terms and subject to the conditions contained
in this Note.

         1. Interest. Interest shall accrue on the outstanding principal amount
of this Note at a rate equal to 5.5% per annum, and shall be compounded
semi-annually. All interest shall accrue based on a 360-day year for the actual
number of days outstanding. In the event Borrower shall fail to make any payment
under this Note within 10 days after its due date, Borrower shall pay a late
charge, without written notice or additional demand therefor, that is equal to
the lesser of (i) 5% of the amount not paid in a timely manner or (ii) the
maximum amount permitted by applicable law. Any such late charge shall be
payable with the interest payment on which it is imposed. All payments made
pursuant to this Note shall be applied, first, to any late fees and penalties
hereunder, next, to all accrued and outstanding interest on the Loan, and lastly
to the principal amount outstanding.


         2.       Payment.

                (a) Method of Payment. All payments hereunder shall be made in
lawful currency of the United States and in immediately available funds at the
principal office of Holder at 3375 Mitchell Lane, Boulder, CO 80301, or at such
other place as Holder may from time to time designate. Any payments by check
shall be accepted subject to collection in immediately available funds.

                  (b) Scheduled Payment. The entire outstanding Principal Sum of
this Note, together with all accrued and unpaid interest, late charges,
expenses, and fees, shall be due and payable in full on the last business day
preceding the fifth anniversary of the date this Note is made.

                  (c) Mandatory Prepayment. Accrued and unpaid interest,
together with the Principal Sum, if not sooner paid, shall be immediately due
and payable on the earliest of: (i) the date Borrower is no longer the
beneficial owner of the Shares; (ii) the date of termination of Borrower's
employment with Holder pursuant to the Employment Agreement between Borrower and
Holder dated March 6, 2001 (the "Employment Agreement"); (iii) thirty days after
the achievement of the "Performance Targets" (defined below); and (iv) the
acceleration of the maturity of the Loan as provided in Section 3. For purposes
of this Note, the Performance Targets are achieved (i) when the fair market
value of the Shares, as measured by the closing stock price on NASDAQ for the
preceding 120 consecutive trading days shall equal at least $30 per share, or
(ii) upon a Change in Control of the Company (as defined in the Employment
Agreement) if the fair market value of the Shares as measured by the closing
stock price on NASDAQ immediately prior to the Change in Control shall equal at
least $20 per share (as such per share prices may be adjusted by Holder to
reflect any stock dividend, extraordinary dividend payable in a form other than
stock, spin-off, stock split, reverse stock split, recapitalization, or similar
transaction affecting the Holder's outstanding securities that is effected
without receipt of consideration).

                  (d)      Optional  Prepayment.  Borrower may, at any time and
from time to time,  without premium or penalty, prepay the outstanding Principal
Sum in whole or in part.

                  (e)      Event  of  Default.  Any of  the  following  shall
constitute an "Event of Default" hereunder: (i) failure to pay the Loan when due
and payable; (ii) any breach by Borrower of the terms of the Stock Purchase
Agreement or this Note; or (iii) death of Borrower.

         3. Acceleration. In the event that Borrower commences an action under
any law relating to bankruptcy, insolvency or relief of debtors, there is
commenced against Borrower an action under any such law which results in the
entry of an order for relief or such action remains undismissed for a period of
60 days or Borrower otherwise becomes insolvent, or upon the occurrence of an
Event of Default, Holder may accelerate this Loan and may, by written notice to
Borrower, declare the entire outstanding Principal Sum and all accrued and
unpaid interest thereon to be immediately due and payable and, thereupon, the
outstanding Principal Sum and all such accrued and unpaid interest shall become
and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are expressly waived by Borrower. If an
Event of Default shall occur, Borrower shall pay Holder all costs and expenses
which Holder may incur in connection with the collection of any monies due under
this Note or in connection with the enforcement of any rights under this Note or
under any other agreement related to the loan evidenced hereby, including
reasonable attorneys' fees and costs not to exceed Fifteen Percent (15%) of the
then outstanding principal balance hereunder. The failure of Holder to
accelerate this Loan shall not constitute a waiver of any of Holder's rights
under this Loan as long as any of the events described in this Section continue.

         4.       Recourse.

                  The Loan shall be a full recourse obligation of Borrower, and
Holder may enforce this Note by any suit, claim, action or proceeding wherein a
money judgment, deficiency judgment or other judgment for personal liability
shall be sought against Borrower. Without limiting Holder's right to exercise
any or all of its rights, powers and remedies upon an Event of Default, Holder
agrees to accept Shares if offered in payment of Borrower's obligation under the
Note, which Shares shall be valued based on their then fair market value as
determined by the closing price on NASDAQ; provided, however, that any Shares
that are "unvested" and subject to the Company's "right of repurchase" under the
Stock Purchase Agreement will not be valued at more than the purchase price paid
by the Borrower for such Shares.

         5.       Miscellaneous.

                  (a) Each right, power and remedy of Holder under this Note or
under applicable laws shall be cumulative and concurrent, and the exercise of
any one or more of them shall not preclude the simultaneous or later exercise by
Holder of any or all such other rights, powers or remedies. No failure or delay
by Holder to insist upon the strict performance of any one or more provisions of
this Note or to exercise any right, power or remedy consequent upon a breach
thereof or default hereunder shall constitute a waiver thereof, or preclude
Holder from exercising any such right, power or remedy. By accepting full or
partial payment after the due date of any amount of principal of this Note,
Holder shall not be deemed to have waived the right either to require payment
when due and payable of all other amounts of principal of this Note or to
exercise any rights and remedies available to it in order to collect all such
other amounts due and payable under this Note.

                  (b) No modification, change, waiver or amendment of this Note
shall be deemed to be made by Holder unless in writing signed by Holder, and
each such waiver, if any, shall apply only with respect to the specific instance
involved.

                  (c) To the extent permitted by law, Borrower waives diligence,
presentment, demand, demand for payment, notice of nonpayment, notice of
dishonor, protest and notice of protest and all other notices or demands in
connection with the delivery, acceptance, performance, default or enforcement of
this Note.

                  (d) Borrower hereby agrees that at any time and from time to
time and with or without consideration, Holder may, without notice to or further
consent of Borrower and without in any manner releasing, lessening or affecting
the obligations of Borrower hereunder: (a) release, surrender, waive, add,
substitute, settle, exchange, compromise, modify, extend or grant indulgences
with respect to, (i) this Note, (ii) all or any part of the collateral or
security for this Note, if any, and (iii) Borrower; and (b) grant any extension
or other postponements of time of payment hereof.

                  (e)      The terms of any documents referred to herein are
incorporated  herein by reference as though fully set forth herein.

                  (f) Borrower hereby acknowledges, consents and agrees that the
provisions of this Note and the rights of all parties mentioned herein shall be
governed by and construed and enforced in accordance with the internal laws of
the State of Colorado, without regard to the conflict of laws and principles
thereof.

                  (g) This Note shall not be assignable by Borrower and shall be
binding upon Borrower's personal representative, heirs and legatees.

                  (h) All notices, demands, requests for modification, consents
or approvals under this Note must be in writing and shall be deemed to have been
properly given when received by Holder at its address as above stated, and when
hand-delivered or mailed by first class mail, postage prepaid, to Borrower at
the address as it appears below, or at such other place as either party may
designate in writing.

                  (i)      Time is of the essence with respect to all matters
hereunder.

         IN WITNESS WHEREOF, Borrower has executed this Note, under seal, on the
day and year first above written.
