                            MULTI-PACK SUPPLY AGREEMENT
                            ---------------------------

          THIS MULTI-PACK SUPPLY AGREEMENT ("Agreement") is made and entered
into as of March 1, 1998 by and between Packaging Resources Incorporated, a
Delaware corporation ("PRI"), and General Mills Operations, Inc., a Delaware
corporation (Yoplait").

                                     RECITALS:

          WHEREAS, Yoplait desires to purchase from PRI and PRI desires to sell
to Yoplait, four-ounce (4 oz.) thermoformed multi-pack cups identified on
Schedule A attached hereto and made a part hereof (the "Cups").

          NOW, THEREFORE, in consideration of the foregoing and the mutual 
agreements set forth herein, and for other good and valuable consideration, 
the receipt and sufficiency of which are hereby acknowledged, the parties 
hereto hereby agree as follows:

          1.   SUPPLY OF CUPS.  PRI shall sell to Yoplait, and Yoplait shall
purchase and take delivery from PRI the Cups in accordance with the estimates
noted in Schedule C attached hereto and made a part hereof.  The parties
acknowledge that Schedule C lists estimates only and that Yoplait does not
guarantee the purchase of any volume of Cups.  However, Yoplait agrees that PRI
will be its exclusive and sole supplier to Trix multipack, Adventure Pack and
Yoplait Original multipack Cups as described on Schedule A, subject to PRI's
ability to perform in accordance with the terms of this Agreement.  Purchases
hereunder shall be in accordance with Yoplait's written purchase orders
submitted to PRI.  In the event there is any conflict between the terms of any
such purchase order terms and the terms of this Agreement, the terms of this
Agreement shall govern.

          2.   TERM.

               (a)  The term of this Agreement shall commence as of March 1,
1998 and shall end on February 28, 2003 ("Initial Term").

               (b)  Yoplait shall have an option to renew the term of this
Agreement for a period of one (1) year after the Initial Term upon written
notice to PRI not less than nine (9) months prior to the end of the Initial
Term.  Any such notice of the exercise of the option to renew shall contain a
new Schedule C.  Other changes to the terms and conditions of this Agreement
shall be as mutually agreed to in writing by the parties.

          3.   PRICE.

               (a)  BASE PRICE.  The base price of the Cups shall be as noted in
Schedule B attached hereto and made a part hereof.

               (b)  RESIN PRICE CHANGES.  Effective March 1, 1999 a price
adjustment for the Cups shall be implemented effective through February 28,
2000.  Such price adjustment shall be based on any increase or decrease between
the market price of polystyrene on March 1, 1998 and such price on March 1,
1999.  On March 1, 2000, a price adjustment for the Cups shall be implemented
effective as of such date based on any increase or decrease between the market
price of polystyrene on March 1, 1999 and such price on March 1, 2000.  Except
as expressly agreed otherwise at any time after March 1, 2000, price adjustments
for the Cups based on any increase or decrease in the market price of
polystyrene shall be implemented when incurred by PRI; provided, however, that
no such price adjustment shall be effective without thirty (30) days prior
written notice to Yoplait.  Any price adjustment pursuant to this Section 3(b)
shall be in accordance with Schedule B.


               (c)  NON-RESIN PRICE CHANGES.  In March of each year of the term
hereof, PRI shall advise Yoplait in writing of all non-resin price increases and
decreases which relate to the manufacture of the Cups.  Upon mutual agreement of
the parties, the base price of the Cups shall be appropriately adjusted and
confirmed by the parties in writing on April 1 of each year of the term hereof;
provided that Yoplait agrees to accept non-resin increases, not to exceed 2%,
when PRI provides appropriate written documentation.  The parties also agree
that to the extent that cost savings are identified, mutually-agreed and
implemented, any such savings shall be passed along to GMI to reduce the price
of the Cups or to reduce such other applicable costs as are paid by GMI.

          4.   PURCHASE OF INVENTORY.  Upon the termination of this Agreement 
for any reason, Yoplait shall purchase from PRI all Cups and related work in
progress then in PRI's inventory; provided, however, that Yoplait shall not be
obligated to purchase any such inventory in excess of the maximum inventory
levels contemplated by the forecasts furnished by Yoplait pursuant to Section 5
hereof.

          5.   FORECASTS OF REQUIREMENTS.  On or about the first (1st) day of
each calendar month during the term hereof, Yoplait shall provide PRI with a
four (4) calendar month forecast of Yoplait's anticipated needs for Cups
hereunder including without limitation, the month, plant location, flavor design
and product group.


                                         -2-

          6.   SPECIFICATIONS AND STANDARDS.  PRI in its performance 
hereunder shall comply with all specifications and quality control standards 
set forth in Schedule A and Schedule D, attached hereto and made a part 
hereof ("specifications").  If PRI shall fail to meet such specifications 
with respect to any Cups, such Cups shall be returned PRI at PRI's sole 
expense and PRI shall, within thirty (30) days of its receipt of such 
defective Cups, either replace such Cups or refund (or credit) the entire 
amount of any base price paid for such Cups.

          7.   INDEMNIFICATION.

               (a)  INDEMNIFICATION BY YOPLAIT.  To the extent that the Cups
supplied hereunder comply with the specifications and standards agreed to by the
parties in accordance with Section 6, Yoplait agrees to indemnify, defend and
hold PRI harmless from and against any and all demands, claims, actions, suits
and proceedings which may at any time be brought against PRI and any and all
liabilities, losses, damages, costs and expenses (including, but not limited to,
reasonable attorney's fees and other legal costs and expenses) which may at any
time be suffered or incurred by PRI, as a result of, arising from or in
connection with the handling, transportation, or use of the Cups or any
products to be sold within the Cups.

               (b)  INDEMNIFICATION BY PRI.  To the extent that PRI shall fail
to meet the specifications and standards agreed to by the parties in accordance
with Section 6 with respect to any Cups, PRI agrees to indemnify, defend and
hold Yoplait harmless from and against any and all demands, claims, actions,
suits and proceedings which may at any time be brought against Yoplait and any
and all liabilities, losses, damages, costs and expenses (including, but not
limited to, reasonable attorney's fees and other legal costs and expenses) which
may at any time be suffered or incurred by Yoplait, as a result of, arising from
or on account of any act or omission in connection with the handling or
transportation of such Cups, or any products to be sold within the Cups;
provided, however, in no event shall PRI be liable for the incidental or
consequential losses or damages (including lost profits) of Yoplait.

          8.   EXCLUSIVITY.  PRI agrees that it will not sell Cups set forth on
Schedule A to any third party.

          9.   MISCELLANEOUS.

               (a) FORCE MAJEURE.  In the event either party hereto shall be
prevented from the performance of any act required hereunder by reason of
strikes, lock-outs, labor troubles, inability to procure materials, failure of
power, restrictive governmental laws or regulations, riots, insurrection, war or
other reasons of a like nature not the fault of, or under the control of, the
party


                                         -3-

delayed in performing work or doing acts required under the terms of this 
Agreement, then performance of such act shall be excused for the period of 
the delay and the period for the performance of any such act shall be 
extended for a period equivalent to the period of such delay, provided the 
party delayed in performing promptly gives written notice to the other party 
of its inability to perform and provided, further, that upon the termination 
of the force majeure event the delayed party promptly commences performance.
