                        THE PROGRESSIVE CORPORATION 1997

                                GAINSHARING PLAN
   2
                                                                   Exhibit 10(B)

                           THE PROGRESSIVE CORPORATION
                              1997 GAINSHARING PLAN


1.   The Progressive Corporation and its subsidiaries ("Progressive" or the
     "Company") have adopted The Progressive Corporation 1997 Gainsharing Plan
     (the "Plan") as part of their overall compensation program. The objective
     of the compensation program is to pay competitive base salaries and for
     gainsharing to bring total cash compensation to the top of the market when
     Core Business and assigned Business Unit or Product performance meets
     expectations. Participants will have the opportunity to earn cash
     compensation in excess of the top of the market when Core Business and
     assigned Business Unit or Product performance exceeds expectations.

2.   Plan participants for each Plan year shall be selected by the Executive
     Compensation Committee (the "Committee") of the Board of Directors of The
     Progressive Corporation from those officers and regular employees of
     Progressive who are assigned primarily to the Core Business or a corporate
     support function as of December 1 of that Plan year. The gainsharing
     opportunity, if any, for those executive officers who participate in The
     Progressive Corporation 1997 Executive Bonus Plan will be provided by and
     be a component of that plan. The Plan shall be administered by or under the
     direction of the Committee.

3.   Annual Gainsharing Payments under the Plan will be determined by
     application of the following formula:

     Annual Gainsharing Payment = Paid Earnings x Target Percentage x
     Performance Factor

4.   Paid Earnings for any Plan year means the following items paid to a
     participant during the Plan year: (a) regular, vacation, sick, holiday,
     funeral and overtime pay, (b) lump sum merit adjustments based on
     performance and (c) retroactive payments of any of the foregoing items
     relating to the same Plan year.

     For purposes of the Plan, Paid Earnings shall not include any short-term or
     long-term disability payments made to the participant, the earnings
     replacement component of any worker's compensation award or any other bonus
     or incentive compensation awards.

     Notwithstanding the foregoing, if the sum of the regular, vacation, sick,
     holiday and funeral pay received by a participant during a Plan year
     exceeds his/her salary range maximum for that Plan year, then his/her Paid
     Earnings for that Plan year shall equal his/her salary range maximum, plus
     any of the following items received by such participant during that Plan
     year: (a) overtime pay, (b) retroactive payments of regular, vacation,
     sick, holiday, overtime and funeral pay and (c) lump sum merit adjustments.

5.   Target Percentages vary by position. Target Percentages for Plan
     participants typically are as follows:



==============================================================================
                     POSITION                                 TARGET %
- ------------------------------------------------------------------------------
                                                         
Policy Team Members, General Managers and Senior             50% - 100%
Process Team Members
- ------------------------------------------------------------------------------
Senior Product Managers (PM's), Senior Claims
Managers and Senior Corporate Function Heads                    35%
- ------------------------------------------------------------------------------
Senior Regional Claims Managers, Function Heads and             25%
PM's
- ------------------------------------------------------------------------------
Regional Claims Managers, Finance Managers and
Group Managers                                                  15%
- ------------------------------------------------------------------------------
Senior Professionals and Managers                               12%
- ------------------------------------------------------------------------------
Professionals and Supervisors (e.g. CSR's, Claims Reps,
etc.)                                                            8%
==============================================================================


     Target Percentages will be established within the above ranges by, and may
     be changed with the approval of, the Chief Executive Officer ("CEO"), Chief
     Financial Officer ("CFO") or Chief Human Resources Officer ("CHRO") and, if
     applicable, the appropriate process leader. Target Percentages also may be
     changed from year to year by such individuals.

6.   The Performance Factor
     ----------------------

     A.   General
          -------

          The Performance Factor shall consist of one or more Profitability and
          Growth Components, as described below. The Profitability and Growth
          Components will be weighted to reflect the nature of the individual
          participant's assigned responsibilities. The weighting factors may
          differ among participants and will be determined, and may be changed
          from year to year, by or under the direction of the CEO, CFO or CHRO.

     B.   Profitability and Growth Components
          -----------------------------------

          The Profitability and Growth Components measure overall operating
          performance of Progressive's core personal and commercial automobile
          insurance business ("Core Business"), as a whole, and the
          participant's assigned Business Unit or Product (as applicable), for
          the Plan year for which an Annual Gainsharing Payment is to be made.
          For purposes of computing a Performance Score for these Components,
          operating performance results are measured by the Gainsharing Matrix,
          as established by or under the direction of the Committee for the Plan
          year, which assigns a Profitability and Growth Performance Score to
          various combinations of profitability (as measured by the Gainsharing
          Combined Ratio) and growth (based on year-to-year change in Net
          Written Premium) outcomes.



   4




          The Gainsharing Combined Ratio is determined for the Core Business and
          each Business Unit or Product (as applicable) as follows:

          1.   Each year, target combined ratios are established by or under the
               direction of the Committee by Product, Distribution Channel and
               New/Renewal business ("Designated Segments"), determined to yield
               an average target policy life combined ratio of 96. Special Lines
               and CV target combined ratios remain at 96 regardless of
               Distribution Channel and whether New or Renewal business.

          2.   A weighted target combined ratio is calculated based on the
               various target combined ratios, weighted based on the Net Earned
               Premium generated by each Designated Segment for the Plan year.

          3.   The actual GAAP combined ratio achieved for the Plan year is
               subtracted from the weighted target combined ratio to determine
               the extent to which performance is over or under target. This
               result, whether positive or negative, is subtracted from the
               average policy life combined ratio target of 96 to determine the
               Gainsharing Combined Ratio.

          The Gainsharing Combined Ratio is then matched with growth in Net
          Written Premium using the Gainsharing Matrix to determine a
          Profitability and Growth Performance Score.

     C.   Component Weighting 
          -------------------

          Profitability and Growth Components for the Core Business and assigned
          Business Unit or Product, as applicable, are weighted as provided
          above. For participants in the Core Business, the typical weighting
          will be as follows:



=========================================================================
                                                      
Profitability and Growth Component                    Weighting
- -------------------------------------------------------------------------
Core Business                                            75%
- -------------------------------------------------------------------------
Business Unit or Product                                 25%
- -------------------------------------------------------------------------
Total                                                    100%
=========================================================================


          There will typically be no Business Unit or Product Profitability and
          Growth Component for participants assigned to a corporate support
          function (such as Finance, Human Resources, Law and Information
          Services) and others who are not assigned primarily to a Business Unit
          or Product. Individualized programs may be developed if and to the
          extent deemed appropriate by the CEO, CFO or CHRO.



   5




          The Performance Score for each Profitability and Growth Component is
          multiplied by the assigned weighting factor to produce a Weighted
          Performance Score. The sum of the Weighted Performance Scores equals
          the Performance Factor. The final Performance Factor can vary from 0
          to 2.0, based on actual performance versus the pre-established
          objectives. In some cases, the Profitability and Growth Performance
          Score for the Core Business or a particular Business Unit or Product
          may be above 2.0 or below 0. The individual scores (positive and
          negative, above 2.0 and below 0) are not adjusted, but go directly
          into the calculation of the Performance Factor, which is capped at 0
          and 2.0.

7.   Subject to Paragraph 8 below, no later than December 31 of each Plan year,
     each participant will receive an initial payment in respect of his or her
     Annual Gainsharing Payment for such Plan year equal to 75% of an amount
     calculated on the basis of Paid Earnings for the first 25 pay periods of
     the Plan year, one pay period of estimated earnings, performance data
     through the first 11 months of the Plan year (estimated, if necessary) and
     one month of forecasted operating results. No later than February 15 of the
     following year, each such participant shall receive the balance of his or
     her Annual Gainsharing Payment, if any, for such Plan year, based on his or
     her Paid Earnings for the entire Plan year and performance data for the
     Plan year.

     Any Plan participant who is then eligible to participate in The Progressive
     Corporation Executive Deferred Compensation Plan ("Deferral Plan") may
     elect to defer all or a portion of the Annual Gainsharing Payment otherwise
     payable under this Plan, subject to and in accordance with the terms of the
     Deferral Plan.

8.   Unless otherwise determined by the Committee or as provided at Paragraph 10
     hereof, in order to be entitled to receive any portion of an Annual
     Gainsharing Payment for any Plan year, the participant must be employed by
     Progressive on the payment date for that portion of the Annual Gainsharing
     Payment. Annual Gainsharing Payments will be net of any legally required
     deductions for federal, state and local taxes and other items.

9.   The right to any Annual Gainsharing Payment hereunder may not be
     transferred, assigned or encumbered by any participant. Nothing herein
     shall prevent any participant's interest hereunder from being subject to
     involuntary attachment, levy or other legal process.

10.  The Plan shall be administered by or under the direction of the Committee.
     The Committee shall have the authority to adopt, alter and repeal such
     rules, guidelines, procedures and practices governing the Plan as it shall,
     from time to time, in its sole discretion, deem advisable.

     The Committee shall have full authority to determine the manner in which
     the Plan will operate, to interpret the provisions of the Plan and to make
     all determinations hereunder. All such interpretations and determinations
     shall be final and binding on Progressive, all Plan participants and all
     other parties. No such interpretation or determination shall be relied on
     as a precedent for any similar action or decision.


   6



     Unless otherwise determined by the Committee, all of the authority of the
     Committee hereunder (including, without limitation, the authority to
     administer the Plan, select the persons entitled to participate herein,
     interpret the provisions thereof, waive any of the requirements specified
     herein and make determinations hereunder and to establish, change or modify
     Performance Components and their respective weighting factors, performance
     targets and Target Percentages) may be exercised by the CEO, CFO or the
     CHRO.

11.  The Plan may be terminated, amended or revised, in whole or in part, at any
     time and from time to time by the Committee, in its sole discretion.

12.  The Plan will be unfunded and all payments due under the Plan shall be made
     from Progressive's general assets.

13.  Nothing in the Plan shall be construed as conferring upon any person the
     right to remain a participant in the Plan or to remain employed by
     Progressive, nor shall the Plan limit Progressive's right to discipline or
     discharge any of its officers or employees or change any of their job
     titles, duties or compensation.

14.  Progressive shall have the unrestricted right to set off against or recover
     out of any Annual Gainsharing Payment or other sums owed to any participant
     under the Plan any amounts owed by such participant to Progressive.

15.  This Plan supersedes all prior plans, agreements, understandings and
     arrangements regarding bonuses or other cash incentive compensation payable
     by or due from Progressive, other than The Progressive Corporation 1996
     Process Management Bonus Plan and any successor plans thereto. Without
     limiting the generality of the foregoing, this Plan supersedes and replaces
     The Progressive Corporation 1995 Gainsharing Plan, as heretofore in effect
     (the "Prior Plan"), which is and shall be deemed to be terminated as of
     December 31, 1996 (the "Termination Date"); provided, that any bonuses or
     other sums earned under the Prior Plan prior to the Termination Date shall
     be unaffected by such termination and shall be paid to the appropriate
     participants when and as provided thereunder.

16.  This Plan is adopted, and is to be effective, as of January 1, 1997. This
     Plan shall be effective for 1997 and for each calendar year thereafter
     unless and until terminated by the Committee.

17.  This Plan shall be interpreted and construed in accordance with the laws of
     the State of Ohio.
