                                    EXHIBIT Q

                                NEW BANK ADDENDUM

                  THIS NEW BANK ADDENDUM, dated ______________________, to the
Amended and Restated Credit Agreement dated as of December 30, 2002 (as
otherwise amended or modified from time to time, the "Credit Agreement"), among
Olympic Steel, Inc. ("Company"), each of the financial institutions parties
thereto (collectively, the "Banks") and Comerica Bank, as Agent for the Banks.

                              W I T N E S S E T H:

                  WHEREAS, the Credit Agreement provides in Section 2.17 thereof
that a financial institution, although not originally a party thereto, may
become a party to the Credit Agreement with the consent of the Company and the
Agent by executing and delivering to the Agent a New Bank Addendum to the Credit
Agreement in substantially the form of this New Bank Addendum; and

                  WHEREAS, the undersigned New Bank was not an original party to
the Credit Agreement but now desires to become a party thereto;

                  NOW, THEREFORE, the New Bank hereby agrees as follows:

                  The New Bank hereby confirms that it has received a copy of
the Credit Agreement and the exhibits and schedules referred to therein, and all
other Loan Documents which it considers necessary, together with copies of the
other documents which were required to be delivered under the Credit Agreement
as a condition to the making of the loans thereunder. The New Bank acknowledges
and agrees that it: (a) has made and will continue to make such inquiries and
has taken and will take such care on its own behalf as would have been the case
had its commitment been granted and its loans been made directly by such New
Bank to the Company without the intervention of the Agent or any other Bank; and
(b) has made and will continue to make, independently and without reliance upon
the Agent or any other Bank, and based on such documents and information as it
has deemed appropriate, its own credit analysis and decisions relating to the
Credit Agreement. The New Bank further acknowledges and agrees that the Agent
has made any representations or warranties about the creditworthiness of the
Company or any other party to the Credit Agreement or any other of the Loan
Documents, or with respect to the legality, validity, sufficiency or
enforceability of the Credit Agreement, or any other of the Loan Documents.

                  New Bank represents and warrants that it is a Person to which
assignments are permitted pursuant to Sections 14.8(c) and (d) of the Credit
Agreement.

                  Except as otherwise provided in the Credit Agreement,
effective as of the Effective Date (as defined below):

                  (a) the New Bank (i) shall be deemed automatically to have
become a party to the Credit Agreement and the other Loan Documents, and to have
all the rights and obligations of a party to the Credit Agreement and the other
Loan Documents, as if it were an original signatory; and (ii) agrees to be bound
by the terms and conditions set


                                       13


forth in the Credit Agreement and the other Loan Documents as if it were an
original signatory thereto; and

                  (b) the New Bank shall be a Revolving Credit Bank and its
Percentage of the Revolving Credit (and its risk participation in Letters of
Credit) shall be as set forth in the attached revised Schedule 1.2(Percentages);
provided any fees paid prior to the Effective Date, including any Letter of
Credit Fees, shall not be recalculated, redistributed or reallocated by Company,
Agent or the Banks.

                  As used herein, the term "Effective Date" means the date on
which all of the following have occurred or have been completed, as reasonably
determined by the Agent:

                  (1) the Company shall have paid to the Agent, all interest,
fees (including the Revolving Credit Facility Fee) and other amounts, if any,
accrued to the Effective Date for which reimbursement is then owing under the
Credit Agreement;

                  (2) New Bank shall have remitted to the Agent funds in an
amount equal to its Percentage of all Advances of the Revolving Credit
outstanding as of the Effective Date; and

                  (3) the Company shall have executed and delivered to the Agent
for the New Bank, a new Revolving Credit Note payable to such New Bank in the
face amount of such New Bank's Percentage of the Revolving Credit Aggregate
Commitment (after giving effect to this New Bank Addendum, and any other New
Bank Addendum executed concurrently herewith).

                  The Agent shall notify the New Bank, along with Company, of
the Effective Date. The New Bank shall deliver herewith to the Agent
administrative details with respect to the funding and distribution of Advances
(and Letters of Credit) as requested by Agent.

                  Terms defined in the Credit Agreement and not otherwise
defined herein shall have their defined meanings when used herein.



                                       14




         IN WITNESS WHEREOF, the undersigned has caused this New Bank Addendum
to be executed and delivered by a duly authorized officer on the date first
above written.
