                                 TO SCHEDULE 13D

          This amended statement relates to the Common Stock, $1.00 par value

Jaffray Inc. intended to comply with Rule 10b5-1(c) of the Securities Exchange
Act of 1934, as amended, pursuant to which CRL intended to sell up to an
aggregate of 78,000 Shares it owns. The Rule 10b5-1 Plan terminated on November
30, 2002 with no sales of Shares being made pursuant to the Rule 10b5-1 Plan.

          As also previously reported, the 62 Trust intended to dispose of up to
100,000 Shares it owns by distributing such Shares to its beneficiaries on or
before October 31, 2002 (the "Distribution"). The Distribution has not occurred
and the 62 Trust has determined not to complete the Distribution at this time.

          The description of the Rule 10b5-1 Plan is qualified in its entirety
by the provisions of such agreement previously filed as Exhibit A to Amendment
29 to this statement.

          On December 18, 2002, CRL entered into, effective as of August 31,
2002, a First Amendment to Second Amended and Restated Credit Agreement (the
"First Amendment") with the The Northern Trust Company ("Northern Trust"), which
amended the Second Amended and Restated Credit Agreement effective as of August
31, 2001 (the "Credit Agreement"), which was previously filed as Exhibit A to
Amendment 28 to this statement. The Amendment terminated the revolving portion
of the Credit Agreement and extended the term of the Credit Agreement to, and
waived CRL's defaults under the Credit Agreement until, February 15, 2003. Mr.
Carroll ratified his prior guaranty and pledge agreement in favor of Northern
Trust in connection with the Credit Agreement and consented to the First
Amendment by executing the First Amendment. The

58 Trust ratified its prior pledge agreement in favor of Northern Trust in
connection with the Credit Agreement and consented to the First Amendment by
executing the First Amendment.

          The description of the First Amendment is qualified in its entirety by

exhibit.

          to Securities of the Issuer.

                                 FIRST AMENDMENT
                 TO SECOND AMENDED AND RESTATED CREDIT AGREEMENT

     This First Amendment to Second Amended and Restated Credit Agreement (this
"AMENDMENT"), dated December 18, 2002, but effective as of August 31, 2002 (the
"EFFECTIVE DATE"), is entered into between CRL, INC., a Delaware corporation
(the "BORROWER"), and THE NORTHERN TRUST COMPANY, an Illinois banking

                                    RECITALS:

     A.   The Borrower and the Lender have entered into a Second Amended and
Restated Credit Agreement dated as of August 31, 2001 (the "CREDIT AGREEMENT";
the terms defined in the Credit Agreement and not otherwise defined herein shall
be used herein as defined in the Credit Agreement).

     B.   As of August 31, 2002, the Lender's Revolving Commitment, any
obligation to make Revolving Loans and any obligation to issue Revolving Letters
of Credit all terminated and the Lender has no further obligations in connection
therewith.

     C.   As of August 31, 2002, the Term Letters of Credit have been fully
drawn, cancelled and all amounts drawn and not reimbursed by the Borrower to the
Lender have been converted into the Term Loan. As of August 31, 2002, the Lender
has no obligation to issue any Term Letter of Credit.

     D.   As of December 18, 2002, the aggregate principal amount of the Term
Loan outstanding is $5,710,000 and all accrued and unpaid interest is
$12,133.76.

     E.   The Term Loan was due and payable on August 31, 2002 and has not been
paid in full.

     F.   The Borrower and the Lender desire to amend the Credit Agreement in
certain respects as set forth herein, including without limitation to (i)
eliminate references to the Revolving Commitment and the obligation of the
Lender to make Revolving Loans and issue Revolving Letters of Credit thereunder
and (ii) extend the Termination Date with regard to the Term Loan only.

     G.   Certain Events of Default have occurred and are continuing under the
Credit Agreement and Borrower has requested Lender to waive such Events of
Default. Lender agrees to waive such Events of Default on the terms contained
herein.

     NOW, THEREFORE, the parties hereto agree as follows:

the Trust, the Trust Pledge Agreement, and have consented to this Amendment,
each by signing the signature page to this Amendment.

          (h) OTHER. Such other documents as the Lender may reasonably request.

          4.2. NO DEFAULT. After giving effect to the waiver in SECTION 5
hereof, as of the closing date hereof, no Event of Default or Default under the
Loan Documents shall have occurred and be continuing.

          4.3. REPRESENTATIONS AND WARRANTIES. After giving effect to the waiver

Loan Documents and in SECTION 3 of this Amendment shall be true and correct as
though made on such date, except for such changes as are specifically permitted
under the Credit Agreement.

     5. WAIVER. Borrower has advised Lender that an Event of Default occurred
under SECTION 8.1(d) of the Credit Agreement as a result of the Obligations
exceeding the Collateral Base. Borrower has also advised Lender that an Event of
Default has occurred and is continuing under SECTION 8.1(f) of the Credit
Agreement as a result of Borrower's Subsidiary, Freezing in Florida, LLC,
violating certain financial covenants under Section 4.1(u) of that certain
Letter of Credit and Reimbursement Agreement between Freezing in Florida, LLC
and Bank of America National Association dated as of September 1, 1999 for the
periods ending March 31, 2002, June 30, 2002, September 30, 2002 and December
31, 2002. Borrower has further advised Lender that the Event of Default under
SECTION 8.1(f) of the Credit Agreement that is now occurring as a result of
Freezing in Florida, LLC's violation of Section 4.1(u) of the aforementioned
Letter of Credit and Reimbursement Agreement may continue for an unknown time
period in the future. On the Effective Date, Lender waives the aforedescribed
Events of Default under SECTION 8.1(d) and SECTION 8.1(f) of the Credit
Agreement through February 15, 2003 only. Lender's waiver of said Events of
Default also extends for such specified time periods and in accordance with this
waiver to any event of default, default or similar event that may have occurred
in any other Loan Document as a result of said Events of Default. Lender's
waiver of said Events of Default is limited to the specific facts giving rise to
such Events of Default described above and shall not be deemed a waiver of or
consent to any other failure to comply with the terms of SECTION 8.1 of the
Credit Agreement or any other provisions of the Credit Agreement. Such waiver
shall not prejudice or constitute a waiver of any right or remedies which the
Lender may have or be entitled to with respect to any other breach of SECTION
8.1 or any other provision of the Credit Agreement. Further, except as expressly
provided herein, this Amendment shall not establish a custom or course of
dealing and does not waive, limit or postpone any of the liabilities or
obligations of the Borrower, whether under the Credit Agreement, as amended
hereby, or any of the other Loan Documents or otherwise, and any discussions
(whether written or oral) which have occurred or which hereafter may occur are
not, and shall not be deemed to be, a waiver, limitation or postponement of any
of the Lender's rights and remedies under the Credit Agreement, as amended
hereby, any of the other Loan Documents or applicable law, all of which rights
and remedies hereby expressly are reserved.

     6. RELEASES OF CLAIMS. In consideration of the Lender's extension of the
Termination Date, the Borrower hereby irrevocably releases and forever
discharges the Lender

                                  Page 19 of 21


and its affiliates, subsidiaries, successors, assigns, directors, officers,
employees, agents and attorneys (each a "RELEASED PERSON") of and from all
damages, loses, claims, demands, liabilities, obligations, actions and causes of
action whatsoever which the Borrower may now have or claim to have against any
Released Person on account of or in any way touching, concerning, arising out of
or founded upon this Amendment, the Credit Agreement, as amended hereby, and the
other Loan Documents, and the transactions contemplated hereby and thereby,
whether presently known or unknown and of every nature and extent whatsoever
arising before or through the date hereof.

     7. GENERAL.

          7.1. EXPENSES. The Borrower agrees to pay the Lender upon demand for
all reasonable expenses, including reasonable attorneys' and legal assistants'
fees (which attorneys and legal assistants may be employees of the Lender),

execution of this Amendment, the Replacement Note and any documents required to
be furnished herewith or therewith.

          7.2. LAW. THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS.

          7.3. SUCCESSORS. This Amendment shall be binding upon the Borrower and
the Lender and their respective successors and assigns, and shall inure to the

DOCUMENTS. The Credit Agreement, as amended hereby, and the other Loan Documents

counterparts, and any party hereto may execute one or more such counterparts,
