EXHIBIT NO. 10(A)
                                    AGREEMENT

                  This AGREEMENT, dated as of the 16 day of May, 2001 (this
"Agreement"), is by and between THE PROGRESSIVE CORPORATION, an Ohio corporation
(the "Company"), and Glenn Renwick (the "Executive").

         A.       The Executive is a senior executive of the Company and has
made and is expected to continue to make major contributions to the short- and
long-term profitability, growth and financial strength of the Company.

         B.       In the event of a change in ownership or control of the
Company, the Executive may be entitled to (or otherwise receive) certain
payments or other benefits from the Company. The Company recognizes that the
effect of certain tax laws could be to diminish substantially the value of such
payments and benefits.

         C.       In order to encourage the continued attention and dedication
of the Executive to Executive's duties with the Company in the event of a change
in control, and to provide additional inducement for the Executive to continue
to remain in the employ of the Company, the Company desires to ensure that the
Executive receives the full value of the payments and benefits to which the
Executive may be entitled (or otherwise receive) in the event of a change in
ownership or control of the Company.

                  NOW, THEREFORE, in consideration of the foregoing, intending
to be legally bound, the parties hereto hereby agree as follows:

         1.       CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.

                  1.1 Except as otherwise provided herein, in the event it is
determined (as hereinafter provided) that any payment or distribution hereafter
made by the Company or any of its affiliates to or for the benefit of the
Executive, whether paid or payable or distributed or distributable pursuant to
or by reason of any agreement, policy, plan, program or arrangement, including,
without limitation, any stock option, performance share, performance unit, stock
appreciation right, restricted stock award, or similar right, or the lapse or
termination of any restriction on or the vesting or exercisability of any of the
foregoing, or otherwise (the "Payments"), would be subject to the excise tax
imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code") (or any successor provision thereto) by reason of being considered
"contingent on a change in ownership or control" of the Company within the
meaning of Section 280G(b)(2)(A)(i) of the Code (or any successor provision
thereto) or to any similar tax imposed by state or local law, or any interest or
penalties with respect to such tax (such tax or taxes, together with any such
interest and penalties, being hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment (the "Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including, without limitation, any income taxes (and any
interest and penalties imposed with respect thereto) and


                                     -1-

   2

Excise Tax imposed upon the Gross-Up Payment, the Executive retains an amount of
the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

                  1.2 Subject to the provisions of Section 1.3, all
determinations required to be made under this Agreement, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, shall be made
by PricewaterhouseCoopers LLP or such other nationally recognized independent
accounting firm as may be mutually agreed upon by the parties (the "Accounting
Firm") that shall provide detailed supporting calculations both to the Company
and the Executive within 15 business days of the receipt of notice from the
Executive that there has been a Payment or such earlier time as is requested by
the Company. In the event that the Accounting Firm is serving as accountant or
auditor for the individual, entity or group effecting the change in ownership or
control that gives rise to the Excise Tax, the Board of Directors of the Company
shall appoint another nationally recognized accounting firm to make the
determinations required hereunder (which accounting firm shall then be referred
to as the Accounting Firm hereunder). All fees and expenses of the Accounting
Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined
pursuant to this Section 1.2, shall be paid by the Company to the Executive
within five business days of the Company's receipt of the Accounting Firm's
determination. Any determination by the Accounting Firm shall be binding upon
the Company and the Executive, absent manifest error. As a result of the
uncertainty in the application of Section 4999 of the Code that may exist at the
time of the initial determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments that will not have been made by the Company
should have been made (the "Underpayment"), consistent with the calculations
required to be made hereunder. In such event, if after the Company exhausts its
remedies pursuant to Section 1.3, the Executive is required to make a payment of
any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and any such Underpayment shall be promptly paid
by the Company to or for the benefit of the Executive.

                  1.3 The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service, or any state or local taxing authority,
that, if successful, would require the payment by the Company of the Gross-Up
Payment; provided, however, that failure by the Executive to provide such notice
pursuant to this Section 1.3 will relieve the Company of its obligations
hereunder with respect to such claim only if, and only to the extent that, the
Company is prejudiced thereby. Such notification shall be given as soon as
practicable but no later than 10 business days after the Executive is informed
in writing of such claim and shall apprise the Company of the nature of such
claim and the date on which such claim is requested to be paid. The Executive
shall not pay such claim prior to the expiration of the 30-day period following
the date on which the Executive gives such notice to the Company (or such
shorter period ending on the date that any payment of taxes with respect to such
claim is due). If the Company notifies the Executive in writing prior to the
expiration of such period that the Company desires to contest such claim, the
Executive shall:

                      (a) promptly give the Company any information reasonably
     requested by the Company relating to such claim,


                                      -2-
   3
                      (b) promptly take such action in connection with
     contesting such claim as the Company shall reasonably request in writing
     from time to time, including, without limitation, accepting legal
     representation with respect to such claim by an attorney reasonably
     selected by the Company,

                      (c) cooperate with the Company in good faith in order
     effectively to contest such claim, and

                      (d) permit the Company to participate in any proceedings
     relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest, and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provisions of
this Section 1.3, the Company shall control all proceedings taken in connection
with such contest, and, at its sole option, may pursue or forgo any and all
administrative appeals, proceedings, hearings and conferences with the
applicable taxing authority in respect of such claim and may, at its sole
option, either direct the Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and, if so requested by the
Company, the Executive agrees to prosecute such contest to a determination
before any administrative tribunal, in a court of initial jurisdiction and in
one or more appellate courts, as the Company shall determine; provided, however,
that, if the Company directs the Executive to pay such claim and sue for a
refund, the Company shall advance the amount of such payment to the Executive,
on an interest-free basis, and shall indemnify and hold the Executive harmless,
on an after-tax basis, from any Excise Tax or income tax (including interest or
penalties with respect thereto) imposed with respect to such advance or with
respect to any imputed income with respect to such advance; and provided,
further, that any extension of the statute of limitations relating to payment of
taxes for the taxable year of the Executive with respect to which such contested
amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Company's control of the contest shall be limited to issues
with respect to which the Gross-Up Payment would be payable hereunder, and the
Executive shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority;
provided, however, that such settlement or contest does not significantly
increase the Company's liability hereunder.

                  1.4 If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 1.3, the Executive becomes entitled
to receive any refund with respect to such claim, the Executive shall (subject
to the Company's complying with the requirements of Section 1.3) promptly pay to
the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after the receipt by the
Executive of an amount advanced by the Company pursuant to Section 1.3, a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund


                                      -3-

prior to the expiration of 30 days after such determination, then such advance
shall be forgiven and shall not be required to be repaid and the amount of such
advance shall offset, to the extent thereof, the amount of Gross-Up Payment
required to be paid.

         2.       TERMINATION. This Agreement, and all of the parties'
respective obligations hereunder, shall terminate upon the termination of the
Executive's employment with the Company and any of its affiliates for any reason
prior to any change in ownership or control described in Section
280G(b)(2)(A)(i) of the Code; provided, however, that this Agreement shall
remain in full force and effect with respect to any right or entitlement of the
Executive to any Payment that is determined to be contingent on such change in
ownership or control, whether paid or payable or distributed or distributable
before or after such termination of the Executive's employment.

         3.       SUCCESSORS AND ASSIGNS.

                  3.1 This Agreement is personal to the Executive, and, without
the prior written consent of the Company, shall not be assignable by the
Executive other than by will or the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.

                  3.2 This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns.

                  3.3 The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company to assume expressly
and agree to perform this Agreement in the same manner and to the same extent
that the Company would be required to perform it if no such succession had taken
place. "Company" means the Company as hereinbefore defined and any successor to
its business or assets as aforesaid, whether by merger, consolidation, purchase
or otherwise, that assumes and is bound to perform this Agreement by operation
of law or otherwise.

         4.       MISCELLANEOUS.

                  4.1 This Agreement shall be governed by and construed in
accordance with the laws of the State of Ohio, without reference to principles
of conflict of laws. The captions of this Agreement are not part of the
provisions hereof and shall have no force or effect. This Agreement may not be
amended or modified other than by a written agreement executed by the parties
hereto or their respective successors and legal representatives.

                  4.6 The Executive's or the Company's failure to insist upon

be a waiver of such provision or right or any other provision or right of this
