Bradley E. Larson, President and Chief Executive Officer
Meadow Valley Corporation
4411 South 40th St., Suite D-11
Phoenix, Arizona 85040

Dear Mr. Larson:

     This letter will serve as a non-binding (except as set forth in paragraph
16 below) expression of intent to acquire all of the capital stock and business
of Ready Mix, Inc., a Nevada corporation ("Ready Mix"), and wholly-owned
subsidiary of Meadow Valley Corporation, a Nevada corporation ("Seller"), on the
following principal terms and conditions:

          1. The purchaser will be RMI Enterprises, LLC, a Nevada limited
     liability company or one of its affiliates ("Purchaser"). Purchaser and
     such affiliate, if any, will be owned by Stuart R. Engs, Jr. or an entity
     or entities wholly owned by Stuart R. Engs, Jr. ("Purchaser's Owner") and
     are not, and at Closing will not be, directly or indirectly controlled by,
     or under common control with any person or entity other than Purchaser's
     Owner.

          2. Purchaser will acquire all of the capital stock ("Stock") of Ready
     Mix, free and clear of all claims and encumbrances of any kind as of the
     "Closing" (defined below in paragraph 10), and Ready Mix shall own free and
     clear of any claim by Seller following the Closing, without limitation, all
     of the following: (a) all current assets listed on Ready Mix's balance
     sheet as of November 30, 2001 as heretofore delived to Purchaser (the
     "November Balance Sheet") consisting of cash, accounts receivable,
     inventories of raw material, work in progress, finished goods and supplies,
     prepaid expenses and other current assets; (b) all property and equipment
     consisting of land and buildings; furniture; fixtures, trucks and other
     equipment; construction in progress; and intellectual property rights owned
     by Ready Mix (and by Seller relating solely to Ready Mix) and necessary for
     the business of Ready Mix, all as listed on Ready Mix's November Balance
     Sheet; (c) all business records including without limitation computer
     files, software, customer records and telephone numbers; (d) all interests
     as lessee in operating leases and assets covered thereby which are required
     to be disclosed in connection with the November Balance Sheet in accordance
     with generally accepted accounting principles; (e) all licenses, permits
     and operating rights; (f) all refundable deposits; and (g) all contracts
     and contract rights.

          3. The consideration to be provided by Purchaser for Stock, and for
     Seller's non-competition covenant referred to in paragraph 7, will be
     Purchaser's undertaking to cause Ready Mix to repay to Seller in cash at
     Closing an amount (the "Intercompany Prepayment Amount") in complete
     discharge of all inter-company debt owing from Ready Mix to Seller. Subject
     to adjustment as noted below in this paragraph



Letter of Intent - Sale of Ready Mix, Inc.

Page 2


     3, the Intercompany Prepayment Amount shall be Four Million One Hundred One
     Thousand Four Hundred Thirty-Four Dollars ($4,101,434). The Intercompany
     Prepayment Amount represents the amount agreed to by the parties working
     off the November Balance Sheet after applying certain adjustments which
     will be set forth specifically on an attachment to the definitive stock
     purchase agreement referred to in paragraph 16. The Intercompany Prepayment
     Amount shall be (a) increased by the amount, if any, that assets set forth
     on the November Balance Sheet are less, and/or the liabilities are greater,
     than the respective assets and liabilities set forth on Ready Mix's balance
     sheet as of the Closing Date (which shall be prepared in accordance with
     the same accounting principles as, and in a manner consistent with, those
     of the November Balance Sheet)("Closing Balance Sheet"); and (b) decreased
     by the amount, if any, that assets set forth on the November Balance Sheet
     are greater, and/or the liabilities are less, than the respective assets
     and liabilities set forth on the Closing Balance Sheet.

          4.   The Intercompany Prepayment Amount shall be paid by Ready Mix in
     cash to Seller at Closing, out of funds provided by Purchaser, by cashier's
     check or wire transfer of immediately available funds.

          5.   Purchaser's acquisition of the Stock notwithstanding, Seller will
     indemnify and defend Purchaser from and against, and Ready Mix and
     Purchaser shall not be obligated with respect to, any liabilities of Seller
     and Ready Mix which are not reflected on the November Balance Sheet or in
     the notes thereto or incurred prior to Closing in the ordinary course of
     business (including, without limitation, liabilities for federal, state and
     local taxes and any liabilities relating to environmental laws), all of
     which shall be assumed by Seller. General real and personal property taxes
     for the current year relating to Ready Mix shall be prorated as of the
     Closing Date for purposes of the Closing Balance Sheet. If the Closing
     occurs before the tax rate is fixed for the current year, the apportionment
     of taxes shall be upon the basis of the tax rate for the immediately
     preceding year applied to the latest assessed valuation of Ready Mix's
     assets.

          6.   Seller shall make reasonable efforts to assist Purchaser and
     Ready Mix in collecting for the account of Ready Mix and Purchaser the
     accounts receivable of Ready Mix which arose prior to the Closing Date and
     shall promptly remit to Purchaser any such amounts received by Seller in a
     manner to be negotiated. Any amounts received by Ready Mix and Purchaser
     from parties that owe accounts receivable to Seller or Ready Mix with
     respect to the period prior to the Closing and accounts receivable to
     Purchaser concerning the period after the Closing shall be applied to the
     invoice specified by the paying party, but if no invoice is specified such
     amounts will be applied on a first-in, first-out basis based on the date of
     the invoice.

          7.   The definitive stock purchase agreement referred to in paragraph
     16 below, will be entered into between Purchaser and Seller governing the
     transaction contemplated hereby ("Transaction") and will contain customary
     representations and warranties, covenants (including a non-competition
     covenant by Seller



Letter of Intent - Sale of Ready Mix, Inc.
February 8, 2002
Page 3


     covering the business of Ready Mix, throughout the geographic region
     currently covered by Seller and Ready Mix for a period of five years
     following the Closing), indemnities and conditions, and a post-Closing
     price adjustment, mechanism, all on terms to be acceptable to the parties.
     Seller's faithful performance of its indemnification covenants shall be
     partially secured by a hold-back of a $300,000 portion of the Intercompany
     Prepayment Amount to be placed into a mutually agreed-upon interest-bearing
     escrow at Closing. The holdback will be released automatically to Seller on
     December 31, 2002 to the extent that the escrow has not been encumbered by
     properly noticed claims, if any, asserted by Purchaser in accordance with
     the terms of the stock purchase agreement. The stock purchase agreement
     shall set forth the allocation of the Intercompany Prepayment Amount
     between (a) satisfaction of intercompany debt and (b) Seller's non-
     competition covenant.

          8.   Seller and Ready Mix will give Purchaser and its attorneys,
     accountants, consultants, and other authorized representatives, an
     opportunity to examine all of the properties and records of Ready Mix and
     properties and records of Seller attributable primarily to Ready Mix (for
     inspection and copying) for the period ending 30 days after the execution
     of this letter by Purchaser or ending on any earlier date when the
     definitive stock purchase agreement is executed. Additional due diligence
     investigation may be necessary only on a basis, and for a period, to be
     mutually agreed upon between Purchaser and Seller. In addition, promptly
     upon the execution of this letter, Purchaser may, upon Purchaser's request,
     retain an acceptable environmental consultant to conduct an environmental
     audit of the real property owned or occupied, or both, by Ready Mix. The
     fees and expenses of such consultant shall be borne by Purchaser.

          9.   From the date of this letter through the earlier of (i) the date
     on which Purchaser notifies Seller in writing that Purchaser has elected
     not to proceed with the Transaction, which Purchaser or Seller may
     determine to do in its respective sole and absolute discretion, and (ii)
     the period specified above in paragraph 8, Seller shall not, and shall not
     permit any of its representatives, officers or directors or other
     authorized representatives or agents to, directly or indirectly, encourage,
     solicit, initiate, conduct or continue discussions or negotiations with, or
     provide any information to, any other entity or person concerning a sale of
     Ready Mix, whether through a sale of stock, assets or business or a merger,
     consolidation or other business combination (collectively, an "Acquisition
     Transaction"); provided, however, that, in response to a wholly unsolicited
     request from a third party with respect to an Acquisition Transaction,
     Seller may furnish information concerning its business, properties or
     assets to such third party if (a) in such case outside counsel to Seller or
     to Seller's board of directors advises Seller's board of directors that in
     the exercise of the fiduciary responsibilities of the members of Seller's
     board of directors such information should be provided to such third party;
     and (b) Seller promptly informs Purchaser of any inquiry (including the
     terms thereof) which Seller may receive in respect of an Acquisition
     Transaction.

     10. The Closing of the Transaction under the definitive stock purchase
agreement ("Closing") shall take place as soon as practicable after the
completion of the due diligence investigation referred to in paragraph 8.

     11. (a)    Purchaser's obligations under the definitive stock purchase
agreement to consummate the Closing will be subject to customary conditions
including, without limitation, the conditions that:

         (i)    Bob Morris shall have entered into a two-year non-competition
     agreement in favor of Purchaser and its successors and assigns preventing
     Mr. Morris from engaging in the business of manufacturing or sales of
     concrete or aggregates other than in connection with Seller's operation of
     (a) its existing Prescott pit aggregate operations only to the extent
     consistent with past practices, and (b) its own site-specific batch plants
     located on Seller's or its subsidiaries' construction job sites solely for
     the purpose of providing concrete to Seller and its subcontractors for use
     on its own job sites. In consideration of the execution and delivery of the
     non-competition agreement by Mr. Morris, Purchaser shall pay consideration
     to Mr. Morris on terms to be specified therein.

         (ii)  Purchaser shall have completed (with results acceptable to
     Purchaser in its sole discretion) its financial and other due diligence
     investigations (including (i) an examination verifying Ready Mix's November
     Balance Sheet and Closing Balance Sheet, (ii) inspection of the condition
     of Ready Mix's plant, machinery and equipment, and (iii) an environmental
     inspection, including the audit referred to in paragraph 8); and

         (iii) Purchaser shall have received a qualified opinion of Seller's
     Nevada counsel to the effect that no legal impediment exists to, or
     required consents or approvals which have not been obtained are required
     for, Seller's and Ready Mix's consummation of the Transaction.

     (b) Seller's obligations under the definitive stock purchase agreement to
consummate the Closing shall be subject to customary conditions including,
without limitation, the conditions that:

          (i)   a reputable recognized investment banking firm selected by
     Seller shall have rendered an opinion to the board of directors of Seller
     as to the fairness of the Transaction to Seller and its shareholders from a
     financial point of view;

                    (ii)      all pending litigation against Seller and its
               directors brought by Silver State Materials Corp. ("SSMC") and
               Cyrus W. Spurlino shall have been dismissed with prejudice; and

                    (iii)     at Closing, all shares of common stock, par value
               $0.001 per share, in Seller ("Shares"), beneficially owned by
               SSMC (consisting of 512,300 Shares) and all Shares beneficially
               owned by Mr. Spurlino (consisting of 47,800 Shares) shall have
               been surrendered to Seller.

               (c)  Seller's, Ready Mix's and Purchaser's obligations under the
          definitive stock purchase agreement to consummate the Closing shall be
          subject to other customary conditions, including, without limitation,
          the following:

                    (i)       Seller and Purchaser shall be satisfied with the
               results of the environmental inspection, if any, performed by the
               consultant referred to in paragraph 8;

                    (ii)      The respective boards of directors of Seller and
               Purchaser shall have approved the Transaction; and

                    (iii)     No litigation shall be pending seeking to enjoin
               the Transaction.

               12.  Each party agrees to consult with the other before issuing
          any press releases or otherwise making any public statement with
          respect to the Transaction and no party shall issue any press release
          or make any such public statement without the prior consent of the
          other except to the extent Seller is required by law to do so.

               13.  Except as expressly contemplated by this letter, Seller will
          operate its business and that of Ready Mix prior to the Closing in the
          normal and ordinary course consistent with past practices.

               14.  Except as otherwise provided by this letter, Purchaser and
          Seller shall each pay its own fees and expenses incurred in connection
          with the Transaction.

               15.  Purchaser shall maintain confidentiality of all information
          received from Seller and/or Ready Mix in connection with the
          Transaction except (i) information in the public domain or
          independently received from a third party with a right to disclose
          this information or (ii) to the extent that disclosure is required by
          law. If the Transaction is not consummated, Purchaser shall promptly
          return to Seller and/or Ready Mix all documents and other written
          material received by Purchaser in connection with the Transaction and
          shall not retain any copies or summaries thereof.

               16.  Except as set forth in paragraphs 8, 9, 12, 14, 15 and this
          16, this letter represents an expression of intent only. Accordingly,
          neither Purchaser, Seller nor Ready Mix will be bound by any terms of

     this 16. Instead, a definitive stock purchase agreement between the parties
     will be prepared by Purchaser for the Transaction in form approved by the
     parties. Such definitive agreement will be the definitive agreement between
     the parties. Unless the definitive agreement is entered into (regardless of
     the reason for it not so having been entered into), neither Purchaser,
     Seller nor Ready Mix shall be under any obligation to the others
     irrespective of any negotiations, agreements or undertakings between, or
     actions taken by, such parties, except for paragraphs 8, 9, 12, 14, 15, and
