                      (Subordination of Required Deposit)


     The undersigned Member-Patron of Unified Western Grocers, Inc. ("Unified
Western") acknowledges that pursuant to the APPLICATION AND AGREEMENT FOR

Unified Western.

     In consideration of financial accommodation given, to be given or continued

     may in the future have with Unified Western are and shall be partially
     subordinated deposit account(s) ("Deposit Account" or "Deposit Accounts")
     which shall in all respects except as modified by this Subordination
     Agreement continue to be governed by and subject to the Membership
     Agreement and all provisions thereof regarding deposits and deposit
     accounts; and

          (B) that all Deposit Accounts of the undersigned are non-transferable
     without the consent of Unified Western, which will normally be withheld,

or other similar agreement or arrangement designed to provide interests rate
protection; (G) in respect of all indebtedness, liabilities or obligations of

(whether real, personal, tangible or intangible) of Unified Western; and (H) in
respect of all modifications, renewals, extensions, replacements and refundings
of any indebtedness, liabilities or obligations of any of the types described in
clauses (A) through (G); provided, however, that the term "Senior Indebtedness"
shall not mean any indebtedness, liabilities or obligations of Unified Western,
contingent or otherwise, whether existing on the date of execution of this
Subordination Agreement or thereafter incurred, (i) to trade creditors arising
or incurred in the ordinary course of Unified Western's business, (ii) in

shall be subordinate and junior in right of payment to all Senior Indebtedness
in the following respects:

          (1)  In the event of any insolvency or bankruptcy proceedings, and any
     receivership, liquidation, reorganization, arrangement or other similar
     proceedings in connection therewith, relative to Unified Western or to its
     creditors, as such, or to its property or assets (whether real, personal,
     tangible or intangible), or in the event of any proceedings for voluntary
     liquidation, dissolution or other winding up of Unified Western, whether or
     not involving insolvency or bankruptcy, then the holders of Senior
     Indebtedness shall be entitled to receive payment in full of all Senior
     Indebtedness (whether accrued prior or subsequent to the commencement of
     such case or proceedings) before the undersigned is entitled to receive any
     payment with respect to that portion of any Deposit Account which consists
     of the Required Deposit, and to that end (but subject to the power of a
     court of competent jurisdiction to make other equitable provision
     reflecting the rights conferred herein upon the Senior Indebtedness and the
     holders thereof with respect to that portion of any Deposit Account which
     consists of the Required

                                       2

     Deposit and the undersigned by a lawful plan of reorganization under
     applicable bankruptcy law) the holders of Senior Indebtedness shall be
     entitled to receive for application in payment thereof any payment or
     distribution of any kind or character, whether in cash or property or
     securities, or by set off or otherwise, which may be payable or deliverable
     in any such proceedings in respect of that portion of any Deposit Account
     which consists of the Required Deposit (other than securities which are
     subordinate and junior in right of payment, at least to the extent provided
     herein with respect to the Required Deposit, to the payment of all Senior
     Indebtedness then outstanding) and the undersigned irrevocably authorizes
     and empowers such holders of Senior Indebtedness to demand, sue for,
     collect and receive any such payment or distribution and to receipt
     therefor, and to file all such claims and take all such action, in the name
     of the undersigned or otherwise, as such holders of Senior Indebtedness may
     determine to be necessary or appropriate for the enforcement of these
     subordination provisions, and the undersigned will also execute and deliver
     such instruments confirming such authorizations and such powers of
     attorney, proofs of claim, assignments of claim and other instruments as
     may be requested by such holders of Senior Indebtedness in order to enable
     such holders to enforce any and all claims upon or in respect of that
     portion of any Deposit Account which consists of the Required Deposit; and
     upon any such insolvency or bankruptcy proceedings, receivership,
     liquidation, reorganization, arrangement or other similar proceedings, or
     voluntary liquidation, dissolution or other winding up, any payment or
     distribution of assets of Unified Western of any kind or character, whether
     in cash, property or securities or by set off or otherwise (other than
     securities which are subordinate and junior in right of payment, at least
     to the extent provided herein with respect to the Required Deposit, to the
     payment of all Senior Indebtedness then outstanding) to which the
     undersigned would be entitled, except for the provisions hereof, shall be
     paid by Unified Western or by any receiver, trustee in bankruptcy,
     liquidating trustee, agent or other person making such payment or
     distribution directly to the holders of Senior Indebtedness (pro rata to
     each such holder on the basis of the respective amounts of Senior
     Indebtedness held by such holder) or their representatives, to the extent
     necessary to pay all Senior Indebtedness in full, after giving effect to
     any concurrent payment or distribution to or for the holders of Senior
     Indebtedness;

          (2)  In the event that any default shall occur and be continuing with
     respect to the payment of Senior Indebtedness, unless payment in full shall
     have first been made on all Senior Indebtedness or such default with
     respect to such Senior Indebtedness shall have been cured or waived in
     accordance with the terms of such Senior Indebtedness, no payment shall be
     made with respect to that portion of any Deposit Account which consists of
     the Required Deposit (including any such payment which would cause such
     default and including any payment in connection with the acquisition by
     Unified Western of the Required Deposit for cash or property other than
     capital stock of Unified Western); and

          (3)  In the event that any default (other than those referred to in
     paragraph (2) above shall occur and be continuing with respect to any
     Senior Indebtedness permitting the holders of such Senior Indebtedness to
     accelerate the maturity thereof,

                                       3

     unless payment in full shall have first been made on all Senior
     Indebtedness or such default with respect to such Senior Indebtedness shall
     have been cured or waived in accordance with the terms of such Senior
     Indebtedness, all payments with respect to that portion of any Deposit
     Account which consists of the Required Deposit (including any such payment
     which would cause such default and including any payment in connection with
     the acquisition by Unified Western of the Required Deposit for cash or
     property other than capital stock of Unified Western) shall be suspended
     during any period:

               (a) of 180 days after the giving of written notice of such
          default by the holders of Senior Indebtedness to Unified Western;
          provided, that only one such notice shall be given pursuant to this
          clause (3)(a) in any 12 consecutive months; or

               (b) in which judicial proceedings shall be pending in respect of
          such default, a notice of acceleration of the maturity of such Senior
          Indebtedness shall have been transmitted to Unified Western in respect
          of such default and such judicial proceedings shall be diligently
          pursued in good faith.

     In the event that any payment or other distribution is made to or received
by the undersigned in contravention of the provisions of paragraphs (1), (2)
and/or (3) above, then such payment or other distribution shall be held by the
undersigned for the benefit of, and shall be paid over and delivered to, the
holders of Senior Indebtedness (pro rata as their interests shall appear) or to
their representative or the trustee under the indenture or other agreement (if
any) pursuant to which Senior Indebtedness may have been issued, for application
to the payment of all Senior Indebtedness remaining unpaid to the extent
necessary to pay all Senior Indebtedness then due and payable in accordance with
its terms, after giving effect to any concurrent payment or distribution to or
for the holders of Senior Indebtedness.
