GNC/OC:  Shareholder Agreement Summary

            The following amendments were made to the shareholder agreement
            between GNC and OC on June 18, 1996, after OC increased its
            ownership in GNC from 49.5% to 80.3%:

      o     OC will not purchase additional shares of GNC prior to July 1, 1999,
            if after such purchase OC would own more than 81% of GNC unless:

            an offer is made for all the shares of GNC not held by OC; and,

            this offer is accepted by the majority of the non-OC shareholders.

      o     If an offer is made prior to July 1, 1999, OC must offer a purchase
            price of at least $18.50 per share.

      o     OC will support a policy of the GNC Board of Directors that any
            repurchase of shares of GNC, prior to July 1, 1999, should be
            approved by the majority of the non-OC Directors of GNC.

      o     If at any time during the five year period after July 1, 1996 OC
            wishes to sell as a block 90% or more of their shareholdings, or
            propose a merger or consolidation involving GNC, they will not do so
            unless:

            in the case of a sale 90% or more of their shareholdings, the
            purchaser offers to purchase the non-OC held shares of GNC for
            equivalent value; and,

            in the case of merger or consolidation all shares are exchanged for
            equivalent value.


                                                                              12

Case Study: Hartford Acquisition of Omni Insurance Group

Consideration Paid

o     Hartford Financial Services Group agreed to buy Omni Insurance Group on
      October 16, 1997 for $31.75 per Omni share.

o     The purchase price represents a 78.9% premium to Omni's market price one
      day prior to the announcement of the transaction.

o     100% of the total consideration of $184.7 million will be paid in cash.

Additional Information

o     The Hartford, which had no nonstandard auto line of its own, had been
      looking to develop the business or to acquire one for about a year.

o     Omni, the nation's 22nd largest provider of nonstandard auto insurance,
      benefited from being the only remaining publicly traded "pure play" in
      nonstandard auto, according to analysts.

o     Omni wrote approximately $10 billion in premiums in 1996 through 3,500
      agents in 11 states.

Case Study: USF&G Acquisition of Titan Holdings

Consideration Paid

o     USF&G Corp. Agreed to acquire Titan Holdings Inc. for $23.20 per share on
      August 8, 1997.

o     The total consideration of $233.0 million will consist of 50% cash and 50%
      common stock.

o     Any increase in USF&G's stock price is to be divided evenly between the
      stock and cash consideration resulting in a floating value for the cash
      and stock portion.

o     The transaction is structured with a 15% collar around USF&G's stock
      price.

Additional Information

o     Titan had been considering strategic alternatives since it hired a
      financial advisor in June.

o     Titan, which generates 65% of its business from non-standard auto (LTM
      total premiums earned of $171.5 million), is expected to fit well with
      Victoria Financial, USF&G's non-standard subsidiary, and add geographic
      diversification.

o     The transaction is expected to be earnings neutral in 1998 and accretive
      to EPS thereafter.

Case Study: GMAC Acquisition of Integon Corp.

Consideration Paid

o     GMAC agreed to acquire Integon Corp. for $26.00 per share on June 23,
      1997, representing a 67.7% premium to market the day prior to
      announcement.

o     The total consideration of $524.7 million will be in the form of cash.

Additional Information

o     Integon reported consistent profits through the third quarter of 1996 but
      posted losses of $16 and $35 million in the 2 subsequent quarters.

o     Following the first quarter earnings release, Integon announced that they
      had retained a financial advisor to consider strategic alternatives.

o     The purchase price paid by GMAC is considered to be relatively rich given
      Integon's financial position, financial leverage (debt/equity ratio of
      93.0%) and operating leverage (premiums written/statutory surplus of
      3.0x).

o     GMAC currently has a presence in the insurance industry through Motors
      Insurance Corp.

Anthem Insurance Companies, Inc. / Acordia, Inc.

Transaction Summary

o     On June 2, 1997 Anthem announced a cash tender offer for all the

Zurich Group / Zurich Reinsurance Centre Holdings, Inc.

Transaction Summary

o     On April 17, 1997 Zurich Group reached an agreement to purchase for $39.50
      per share in cash the 34% of interest in ZRC that it did not already own.

History

o     ZRC completed its IPO in May 1993, reducing Zurich Group's holdings to
      65.7%.

o     In August 1996, Zurich Group believed that changes in the reinsurance
      market place made a consolidation of ZRC more desirable.

o     On January 13, 1997, Zurich Group made public its intentions to acquire
      the public shares of ZRC for $36.00 per share, $1.00 above ZRC's IPO
      price.

o     In February 1997, after several class action lawsuits had been filed and
      concern from public shareholders that the offer price was unacceptable,
      ZRC informed the parent that its offer of $36.00 per share was inadequate.

o     On April 10, 1997, Zurich Group proposed a revised price of $38.25 per
      share which was rejected by ZRC.

o     On April 17, 1997, Zurich Group offered $39.50 per share for ZRC. This
      offer was ultimately accepted by ZRC.

GNC: Acquisition of Unisun Insurance Company

      Transaction Summary

      o     On October 20, 1997, GNC agreed to acquire Unisun Insurance Company
            ("Unisun") for $26 million in cash.

      o     The transaction is expected to be immediately accretive to earnings,
            and is expected to add $0.08, $0.13 and $0.19 per share in 1998,
            1999 and 2000, respectively.

      Company Overview

      o     Unisun is a leading writer of private passenger automobile liability
            insurance in South Carolina and ranks as a leading service carrier
            for both the North Carolina and South Carolina reinsurance facility.

      o     A large portion of the company's business is ceded to the facility,
            enabling the company to act primarily as a servicer for these
            policies.

      Transaction Benefits

      o     Recent legislation in South Carolina will result in the creation of
            a significant voluntary nonstandard automobile market in March 1999.

      o     There is significant opportunity to realize cost savings.

      o     This acquisition provides GNC with a Southeast market presence and
            provides a platform for further market expansion in that region.


                                                                              44
