EXPLANATORY NOTE

This Registration Statement on Form S-4 (the "Registration Statement") relates to a business combination to be effected pursuant to an Agreement and Plan of Mergers dated June 19, 1998 between Berkshire and General Re (the "Merger Agreement"). The Merger Agreement provides for a form of combination in which Berkshire and General Re will each become a wholly owned subsidiary of NBH, Inc., a new holding company. NBH, Inc. will then take the name "Berkshire Hathaway Inc." (referred to in this Registration Statement as "New Berkshire"). The Merger Agreement also provides that, under certain conditions, the business combination may be restructured (the "Alternative Transaction"). In the Alternative Transaction, General Re will merge with, and become, a wholly owned subsidiary of a subsidiary of Berkshire itself, rather than of New Berkshire, and Berkshire itself will remain the ultimate parent company. Therefore, this Registration Statement constitutes the Registration Statement of New Berkshire or, if the Alternative Transaction occurs, of Berkshire. Berkshire and New Berkshire are both referred to as the "Registrants."


BERKSHIRE HATHAWAY INC. GENERAL RE CORPORATION

August 12, 1998

Dear Fellow Stockholders:

The Boards of Directors of Berkshire Hathaway Inc. and General Re Corporation have both unanimously approved the merger of Berkshire and General Re. If the combination had been completed on June 30, 1998, the combined company would have had a GAAP net worth of approximately $58 billion, the highest of any company in the United States. We expect this combination to enhance the value of both Berkshire and General Re. This proxy statement explains why. We encourage you to read it all, carefully. We also urge you to attend your stockholders' meeting, at which your chairman will answer any questions you have about the transaction.

In the combination, General Re stockholders will receive shares of Class A Common Stock or Class B Common Stock that are identical to the existing Class A and Class B Common Stock of Berkshire. On August 11, 1998, the last trading day for which information was available before this proxy statement was first mailed, the last sale prices of Berkshire's Class A and Class B Common Stock on the New York Stock Exchange were $68,900 and $2,308, respectively.

We are planning to accomplish the combination through concurrent tax-free mergers of Berkshire and General Re into separate subsidiaries of a new holding company, now named NBH, Inc., which will take Berkshire's name after the closing and is called "New Berkshire" in this proxy statement. General Re stockholders will receive for each share they own either 0.0035 of a share of New Berkshire Class A Common Stock or 0.105 of a share of New Berkshire Class B Common Stock, at their election. Berkshire stockholders will receive one share of New Berkshire Class A or Class B Common Stock for each respective share of Berkshire Class A or Class B Common Stock they own.

We expect to receive Internal Revenue Service rulings supporting our conclusion that both of the mergers will be tax-free to the companies and their stockholders (except as to the small amount of cash that General Re stockholders may receive in lieu of receiving fractional shares of New Berkshire stock), although we cannot assure you we will receive such rulings. If, contrary to our expectation, we do not receive the rulings, we have agreed that Berkshire will have the right to restructure the combination to accomplish it in a different fashion. There will be no need to create New Berkshire or to merge Berkshire with a subsidiary of New Berkshire, and the combination will be accomplished solely by General Re merging with an indirect subsidiary of Berkshire itself (rather than New Berkshire). In that event, General Re stockholders will receive the same value in consideration for their shares as the exchange ratio stated above, but Berkshire will pay three percent of that consideration in cash rather than shares, and the gain realized by General Re stockholders on exchanging their shares will be taxable to them. Berkshire's stockholders in that event will continue to own their existing shares in Berkshire, which will become the corporate parent of General Re.

The combination cannot be completed unless the stockholders of both companies approve the merger agreement and we have each scheduled special meetings for our stockholders to vote on the merger agreement. The Boards of Directors of Berkshire and General Re have unanimously determined that the combination and the merger of their respective companies are in the best interest of their stockholders, and each Board unanimously recommends that you vote FOR approval of the merger agreement. YOUR VOTE IS VERY IMPORTANT.

Berkshire stockholders are also being asked to vote on a proposal to increase the number of authorized shares of Berkshire Common Stock.

Whether or not you plan to attend a meeting, please vote by completing the enclosed proxy card and mailing it to us. If you sign, date, and mail your proxy card without indicating how you want to vote, your proxy will be counted as a vote in favor of the proposals submitted at your meeting. If your shares are held in "street name," you must instruct your broker in order to vote. If you fail to return your proxy card or fail to instruct your broker, you will in effect vote against the merger agreement.

The date, times, and places of the special meetings are as follows:

For Berkshire stockholders:    For General Re stockholders:
Wednesday, September 16, 1998  Friday, September 18, 1998
9:30 a.m.                      10:00 a.m.

409 South 16th Street          695 East Main Street
Omaha, Nebraska                Stamford, Connecticut

Stockholders of either company are welcome to attend the meeting of the other.

This Joint Proxy Statement/Prospectus provides you with detailed information about the proposed mergers. Again, we encourage you to read it carefully and understand it before you vote. You may obtain information about our companies from documents that we have filed with the Securities and Exchange Commission.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

AUGUST 12, 1998

TO THE STOCKHOLDERS:

Notice is hereby given that a Special Meeting of the Stockholders of Berkshire Hathaway Inc. ("Berkshire") will be held at the Orpheum Theater, 409 South 16th Street, Omaha, Nebraska, on Wednesday, September 16, 1998 at 9:30
a.m. for the following purposes:

1. To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Mergers dated as of June 19, 1998 (the "Merger Agreement") between Berkshire and General Re Corporation ("General Re") and the transactions contemplated therein (the "Transactions"). The Merger Agreement provides for the merger of Berkshire with a subsidiary of NBH, Inc. ("New Berkshire"), a newly formed Delaware corporation (the "Berkshire Merger"), and the concurrent merger of General Re with a separate subsidiary of New Berkshire (the "General Re Merger" and, together with the Berkshire Merger, the "Mergers"). Pursuant to the Mergers, both Berkshire and General Re will become wholly owned subsidiaries of New Berkshire. At the effective time of the Mergers, each outstanding share of Berkshire Class A Common Stock, par value $5.00 per share ("Berkshire Class A Common Stock"), other than shares owned by Berkshire or its subsidiaries, will be deemed to be converted into one share of New Berkshire Class A Common Stock, par value $5.00 per share, and each outstanding share of Berkshire Class B Common Stock, par value $0.1667 per share ("Berkshire Class B Common Stock"), other than shares owned by Berkshire or its subsidiaries, will be deemed to be converted into one share of New Berkshire Class B Common Stock, par value $0.1667 per share. Alternatively, if Berkshire and General Re cannot obtain certain rulings requested from the United States Internal Revenue Service (the "IRS"), the Merger Agreement provides for the merger solely of General Re with an indirect subsidiary of Berkshire (the "Alternative General Re Merger"). If the Alternative General Re Merger occurs, General Re will become a wholly owned subsidiary of Berkshire (rather than New Berkshire), New Berkshire will not be organized as a new holding company, the Berkshire Merger will not need to occur (and will not occur), and the outstanding shares of Berkshire Class A and Class B Common Stock will remain outstanding and be unchanged.

2. To consider and vote upon a proposal to amend the Restated Certificate of Incorporation of Berkshire to increase to 1,650,000 (from 1,500,000) the number of shares of Berkshire Class A Common Stock, and to increase to 55,000,000 (from 50,000,000) the number of shares of Berkshire Class B Common Stock, authorized for issuance (the "Berkshire Charter Amendment"). The Berkshire Charter Amendment will be made only if the Alternative General Re Merger occurs.

3. To consider and act upon any other matters that may properly come before the meeting or any adjournment thereof.

The Berkshire Board of Directors has fixed the close of business on August 10, 1998 as the record date for determining the stockholders having the right to vote at the meeting or any adjournment thereof. A list of such stockholders will be available for examination by a stockholder for any purpose germane to the meeting during ordinary business hours at the offices of the Corporation at 1440 Kiewit Plaza, Omaha, Nebraska during the ten days prior to the meeting.

The affirmative vote of a majority of the voting power of the outstanding shares of Berkshire Class A Common Stock and Berkshire Class B Common Stock entitled to vote thereon, voting together as a single class, is required to approve and adopt the Merger Agreement and the Transactions, or to approve the Berkshire Charter Amendment.


THE VOTE OF ALL HOLDERS OF BERKSHIRE COMMON STOCK IS IMPORTANT. WHETHER OR NOT YOU ATTEND THE SPECIAL MEETING, PLEASE COMPLETE, SIGN, DATE AND RETURN THE ACCOMPANYING PROXY CARD IN THE POSTAGE PREPAID ENVELOPE AS SOON AS POSSIBLE. IF YOU ATTEND THE SPECIAL MEETING, YOU MAY REVOKE YOUR PROXY AND VOTE YOUR SHARES OF BERKSHIRE COMMON STOCK IN PERSON.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF BERKSHIRE

COMMON STOCK VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE TRANSACTIONS AND TO APPROVE THE BERKSHIRE CHARTER AMENDMENT AT THE SPECIAL MEETING.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

AUGUST 12, 1998

TO THE STOCKHOLDERS:

Notice is hereby given that a Special Meeting of the Stockholders of General Re Corporation ("General Re") will be held at Financial Centre, 695 East Main Street, Stamford, Connecticut, on September 18, 1998 at 10:00 a.m. for the following purposes:

1. To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Mergers dated as of June 19, 1998 (the "Merger Agreement") between General Re and Berkshire Hathaway Inc. ("Berkshire") and the transactions contemplated therein (the "Transactions"). The Merger Agreement provides for the merger of General Re with a subsidiary of NBH, Inc. ("New Berkshire"), a newly formed Delaware corporation (the "General Re Merger"), and the concurrent merger of Berkshire with a separate subsidiary of New Berkshire (the "Berkshire Merger" and, together with the General Re Merger, the "Mergers"). Pursuant to the Mergers, both General Re and Berkshire will become wholly owned subsidiaries of New Berkshire. At the effective time of the Mergers, each outstanding share of General Re Common Stock, par value $0.50 per share ("General Re Common Stock"), other than shares owned by General Re, Berkshire or their respective subsidiaries, will be converted into the right to receive, at the option of the holder, (A) 0.0035 of a share of New Berkshire Class A Common Stock, par value $5.00 per share ("New Berkshire Class A Common Stock") or (B) 0.105 of a share of New Berkshire Class B Common Stock, par value $0.1667 per share ("New Berkshire Class B Common Stock"). Alternatively, if Berkshire and General Re cannot obtain certain rulings requested from the United States Internal Revenue Service (the "IRS"), the Merger Agreement provides for the merger solely of General Re with an indirect subsidiary of Berkshire (the "Alternative General Re Merger"). If the Alternative General Re Merger occurs, General Re will become a wholly owned subsidiary of Berkshire (rather than New Berkshire), New Berkshire will not be organized as a new holding company, and the Berkshire Merger will not need to occur (and will not occur). In that event, at the effective time of the Alternative General Re Merger, each outstanding share of General Re Common Stock, other than shares owned by General Re, Berkshire, or their respective subsidiaries, will be converted into the right to receive, at the option of the holder, (A) 0.003395 of a share of Berkshire Class A Common Stock, par value $5.00 per share ("Berkshire Class A Common Stock"), plus an amount in cash equal to the product of 0.000105 and the Average Trading Price of one share of Berkshire Class A Common Stock or (B) 0.10185 of a share of Berkshire Class B Common Stock, par value $0.1667 per share ("Berkshire Class B Common Stock"), plus an amount in cash equal to the product of 0.00315 and the Average Trading Price of one share of Berkshire Class B Common Stock. The "Average Trading Price" is the average of the high and low trading prices of Berkshire Class A Common Stock or Berkshire Class B Common Stock, as the case may be, as reported on the New York Stock Exchange Composite Tape for each of the five consecutive trading days ending on the last full trading day immediately prior to the date on which the effective time of the merger occurs.

2. To consider and act upon any other matters that may properly come before the meeting or any adjournment thereof.

The General Re Board of Directors has fixed the close of business on August 10, 1998 as the record date for determining the stockholders having the right to vote at the meeting or any adjournment thereof. A list of such stockholders will be available for examination by a stockholder for any purpose germane to the meeting during ordinary business hours at the offices of the Corporation at 695 East Main Street, Stamford, Connecticut, during the ten days prior to the meeting.


The affirmative vote of a majority of the voting power of the outstanding shares of General Re Common Stock and General Re Series A ESOP Convertible Preferred Stock entitled to vote thereon, voting together as a single class, is required to approve and adopt the Merger Agreement and the Transactions.

THE VOTE OF ALL HOLDERS OF GENERAL RE COMMON STOCK IS IMPORTANT.

SUMMARY

The transactions described in this document are complex, in part because the way in which Berkshire and General Re are combined will differ depending upon whether the IRS issues the rulings requested by the companies. This summary highlights selected information from this document but may not contain all the information that is important to you. For a more complete understanding of the Transactions and for a more complete description of the legal terms of the mergers, you should read this entire document carefully, as well as the additional documents we refer you to. See "Where You Can Find More Information" (page 78).
QUESTIONS AND ANSWERS

Q: WHY ARE THE TWO COMPANIES PROPOSING TO MERGE?

A: Berkshire and General Re believe that their combination will create value for both companies' stockholders. The transaction will allow General Re to better serve its clients by accepting attractive reinsurance opportunities that it has declined or been unable to write in the past, due to constraints on its earnings volatility. Removing the constraints will enhance long-term profitability. The combination will allow General Re to retain, rather than to cede to other reinsurers, more of the business it writes, which will increase funds available for investment. Berkshire will allow General Re to grow its international business as quickly as it desires and will provide General Re with abundant capital. Also, combining General Re with Berkshire's other income-generating businesses will increase General Re's flexibility in managing its insurance investments, and the combination will increase Berkshire's existing invested insurance assets by approximately $25 billion.

Q: HOW DOES NEW BERKSHIRE DIFFER FROM BERKSHIRE?

A: Once the mergers occur, New Berkshire will be the holding company owning both Berkshire and General Re, but its corporate characteristics will not differ in any material respect from Berkshire's. The New Berkshire Class A and Class B Common Stock will be identical to Berkshire's existing Class A and Class B Common Stock. The New Berkshire Board of Directors and executive officers will be identical to Berkshire's, except that Ronald E. Ferguson, Chairman and Chief Executive Officer of General Re, will join the New Berkshire Board.

Q: WHAT WILL I RECEIVE FOR MY GENERAL RE STOCK?

A: As we expect the combination to be accomplished, General Re stockholders will receive, at their election, either 0.0035 of a share of New Berkshire Class A Common Stock or 0.105 of a share of New Berkshire Class B Common Stock for each share of General Re common stock they own at the time of the mergers.

However, if the IRS does not issue the rulings we expect, the combination will be accomplished differently (referred to in this document as the "Alternative Transaction"). General Re stockholders will receive the same value in consideration for their shares as the exchange ratio stated in the prior paragraph, but will receive shares of Berkshire, rather than of New Berkshire, and will receive three percent of the consideration in cash, rather than stock. Accordingly, in that event General Re stockholders will receive, at their election, either (A) 0.003395 (i.e., 97% of 0.0035) of a share of Berkshire Class A Common Stock and an amount of cash equal to
0.000105 (i.e., 3% of 0.0035) times the average trading price of a share of Berkshire Class A Common Stock on the NYSE over a five-day period before the merger, or (B) 0.10185 (i.e., 97% of 0.105) of a share of Berkshire Class B Common Stock and an amount of cash equal to 0.00315 (i.e., 3% of 0.105) times the average trading price of a share of Berkshire Class B Common Stock on the NYSE over a five-day period before the merger occurs.

Q: WHAT ARE THE TAX CONSEQUENCES OF THE MERGERS?

A: We expect to receive IRS rulings supporting our conclusion that both the General Re Merger and the Berkshire Merger will be tax-free to General Re stockholders (except as to the small amount of cash that General Re stockholders may receive instead of receiving fractional shares of New Berkshire Class B Common Stock) and to the Berkshire stockholders, although we cannot assure you that we will receive such rulings. If we do not receive the rulings and Berkshire elects to restructure the transaction, the Alternative Transaction will not be taxable to Berkshire or its stockholders, but will be taxable to General Re stockholders.

TAX MATTERS ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE TRANSACTIONS WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF THE TRANSACTIONS TO YOU.

Q: HOW DO I ELECT BETWEEN RECEIVING CLASS A COMMON STOCK AND CLASS B COMMON STOCK?

A: General Re Stockholders: You will make your election when you send in your General Re stock certificate with a transmittal letter that New Berkshire will send to you shortly after the General Re merger occurs. Unless you elect to receive Class A Common Stock, you will receive Class B Common Stock.

Berkshire Stockholders: You will be deemed to receive shares of the same class of New Berkshire stock as the shares of Berkshire stock you now own.

Q: WITH BERKSHIRE'S (AND NEW BERKSHIRE'S) PER SHARE STOCK PRICE SO HIGH, HOW WILL FRACTIONAL SHARES BE HANDLED?

A: New Berkshire will not issue fractional shares. Instead, General Re stockholders who elect to receive New Berkshire Class A Common Stock will receive, in lieu of any fractional share of New Berkshire Class A Common Stock owed to them, as many whole shares of New Berkshire Class B Common Stock as possible, and all General Re stockholders will receive cash in lieu of any fractional share of New Berkshire Class B Common Stock owed to them. To determine the number of New Berkshire Class B shares to be received in lieu of a fractional New Berkshire Class A share, the fraction will be multiplied by 30, because New Berkshire Class B shares will have 1/30th of the economic rights of New Berkshire Class A shares. The amount of cash will be based on the average trading price of Berkshire Class B Common Stock over a five trading-day period before the Mergers occur. Fractional shares will be handled in exactly the same way if General Re stockholders receive Berkshire shares rather than New Berkshire shares. Of course, Berkshire stockholders will not receive any fractional shares of New Berkshire, as the exchange ratio is one-for-one.

The following tables illustrates the Merger Consideration to General Re stockholders. In these tables, the "value of a Class A or Class B share" means the average trading price of such a share on the NYSE over a five-day period before the merger.

Q: SHOULD I SEND IN MY GENERAL RE OR BERKSHIRE STOCK CERTIFICATE NOW?

A: No. After the mergers are completed, we will send General Re stockholders written instructions for exchanging their stock certificates. Berkshire stockholders will keep their existing stock certificates, which will automatically represent shares in New Berkshire if the Berkshire Merger occurs.

Q: WHAT DO I NEED TO DO NOW?

A: Please mail your signed proxy card in the enclosed postage prepaid return envelope as soon as possible, so that your shares may be represented and voted at the appropriate stockholders' meeting. YOUR VOTE IS VERY IMPORTANT.

If you sign and send in your proxy and do not indicate how you want to vote, your proxy will be counted as a vote in favor of the proposals. If you do not vote or you abstain, it will have the effect of a vote against the proposals. You may withdraw your proxy up to and on the day of your stockholders' meeting by following the directions on page 49.

Berkshire's special meeting will take place on Wednesday, September 16, 1998 at 9:30 a.m. and General Re's special meeting will take place on Friday, September 18, 1998 at 10:00 a.m. You should sign and mail your proxy card even if you are planning to attend your meeting as you can still withdraw your proxy, change your vote or attend your meeting and vote in person.

Q: WHAT AM I BEING ASKED TO VOTE UPON?

A: General Re stockholders: You are being asked to approve the Merger Agreement which provides that General Re will become, through merger, a wholly owned subsidiary of either New Berkshire or Berkshire. We expect General Re to become a subsidiary of New Berkshire, in which event the transaction will be tax-free to General Re stockholders (except as to the small amount of cash that General Re stockholders may receive in lieu of receiving fractional shares of New Berkshire Class B Common Stock). However, we cannot be certain that the IRS will issue the rulings we have requested. If the IRS does not, Berkshire has the right to elect the Alternative Transaction. Under the Alternative Transaction, the gain realized on exchanging your shares will be taxable to you. You are being asked to approve both alternatives. The taxable alternative will occur only if the IRS will not issue the rulings that we have requested.

Berkshire stockholders: You are being asked to approve the Merger Agreement, including the merger of Berkshire into a subsidiary of New Berkshire. New Berkshire will be organized with authorized capital of 1,650,000 shares of Class A Common Stock and 55,000,000 shares of Class B Common Stock. If General Re merges with a subsidiary of Berkshire, rather than New Berkshire (because the IRS would not issue the rulings we have requested), then Berkshire will have issued a substantial portion of its available authorized shares. Accordingly, you are also being asked to approve an increase in the number of authorized shares of Berkshire's common stock from 1,500,000 to 1,650,000 shares of Berkshire Class A Common Stock and from 50,000,000 to 55,000,000 shares of Berkshire Class B Common Stock. This increase in Berkshire's authorized shares will occur only if the Alternative Transaction occurs (so that General Re merges with a subsidiary of Berkshire, rather than New Berkshire), but this increase is not required, and is not a condition, for the combination to be accomplished in that alternative fashion.

Q: WHAT VOTE IS REQUIRED FOR APPROVAL?

A: The mergers must be approved:

. by holders of a majority of the votes entitled to be cast by holders of the outstanding shares of General Re Common Stock and General Re's Series A ESOP Convertible Preferred Stock, who vote together as a single class, and

. by holders of a majority of the votes entitled to be cast by holders of the outstanding shares of Berkshire Class A Common Stock and Berkshire Class B Common Stock, who vote together as a single class.

4

The increase in Berkshire's authorized common stock must be approved by a majority of the votes entitled to be cast by holders of the outstanding shares of Berkshire Class A Common Stock and Berkshire Class B Common Stock, who vote together as a single class.

Holders of Berkshire Class A Common Stock are entitled to one vote per share, and holders of Berkshire Class B Common Stock are entitled to 1/200 of a vote per share, on the matters to be considered at the Berkshire Meeting.

Q: WHAT DO THE BERKSHIRE AND GENERAL RE BOARDS OF DIRECTORS RECOMMEND?

A: Each Board of Directors unanimously approved the merger agreement and recommends that their company's stockholders vote FOR the proposal to approve the Merger Agreement and the transactions contemplated thereby, including the Alternative Transaction. The Berkshire Board also recommends that Berkshire stockholders vote FOR the proposal to increase Berkshire's authorized common stock.

Q: WHAT RISKS SHOULD I CONSIDER?

A: General Re stockholders should recognize that the exchange ratios of 0.0035 of a New Berkshire Class A share or 0.105 of a New Berkshire Class B share (or 97% thereof if the Alternative General Re Merger occurs) are fixed. These exchange ratios will not change even if the market price of Berkshire stock decreases before the General Re merger occurs. Accordingly, the market value of the New Berkshire (or Berkshire) stock you receive when the merger occurs may be lower than the current market value of Berkshire's stock.

General Re stockholders should also recognize that the Alternative General Re Merger will occur if the IRS will not issue the rulings we have requested. In that event, the excess of the market value of both the shares and the cash received by General Re stockholders over such holders' tax basis in General Re stock will be a taxable gain, while the value of the merger consideration will not be increased.

Both companies' stockholders should review "Certain Risk Factors and Other Investment Considerations" on pages 15 through 16, as well as the countervailing factors considered by each company's Board of Directors described under "The Transactions--Reasons for the Transactions; Recommendations of the Boards of Directors."

Q: WHEN ARE THE MERGERS EXPECTED TO OCCUR?

A: We are working to complete the Mergers during the fourth quarter of 1998.

Q: WHAT WILL NEW BERKSHIRE'S DIVIDEND POLICY BE?

A: New Berkshire will continue Berkshire's dividend policy. Berkshire has not declared a cash dividend since 1967 and has no present intention to pay a dividend on either its Class A or Class B Common Stock in the future.

Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY SHARES FOR ME?

A: Your broker will vote your shares only if you provide instructions on how to vote; except that brokers who hold shares of Berkshire stock as nominees will have discretionary authority to vote such shares for the increase in Berkshire's authorized common stock. Otherwise, without instructions, your shares will not be voted. Shares that are not voted will have the effect of votes against the proposals.

THE COMPANIES

COMPARATIVE PER SHARE MARKET PRICE INFORMATION (PAGE 57)

Shares of Berkshire and General Re common stock are each listed on the New York Stock Exchange. On June 19, 1998 and August 11, 1998, the last full trading day on the New York Stock Exchange prior to the public announcement of the Transactions and prior to the date of first mailing of this Joint Proxy Statement/Prospectus, respectively, General Re common stock closed at $220 1/4 and $233 1/16 per share, Berkshire Class A Common Stock closed at $80,900 and $68,900 per share and Berkshire Class B Common Stock closed at $2,705 and $2,308 per share.

APPROVALS (PAGE 42)

We are prohibited by U.S. antitrust laws from completing the transactions until after we have furnished certain information and materials to the Antitrust Division of the Department of Justice and the Federal Trade Commission and a required waiting period has ended. We each filed the required forms, and the waiting period ended on August 9, 1998. However, the Department of Justice and the Federal Trade Commission continue to have the authority to challenge the transactions on antitrust grounds before or after the mergers are completed.

We are each required to make filings with or to obtain approvals from certain domestic and international regulatory authorities in connection with the transactions. These consents and approvals include the approval of the insurance commissioners of the states of Connecticut, Delaware, Ohio and North Dakota, governmental entities in Australia, South Africa, Hong Kong and the United Kingdom, and the European Commission.

We cannot predict whether we will obtain all required approvals before we complete the transactions, or whether any approvals will include conditions that would be detrimental to New Berkshire. It is a condition to our completing

7

the transactions that we obtain all approvals that are material to either of us or which, if not received, would materially dilute the aggregate benefits to the parties of the Transactions.

CONDITIONS TO THE TRANSACTIONS (PAGE 50)

We will complete the Transactions only if we satisfy several conditions, including the following:

. a majority of the voting power of the General Re Voting Stock and Berkshire Common Stock vote to adopt the Merger Agreement and the Transactions;

. no legal restraints or prohibitions prevent the consummation of the Transactions;

. the IRS issues certain rulings we have requested or Berkshire elects the Alternative Transaction;

. all approvals and authorizations have been received, except for those which are not material or would not materially dilute the aggregate benefits to the parties of the Transactions;

. our lawyers render certain tax opinions.

Unless prohibited by law, either General Re or Berkshire could elect to waive a condition that has not been satisfied and complete the Transactions anyway.

TERMINATION OF THE MERGER AGREEMENT (PAGE 53)

We can jointly agree to call off the transactions at any time before completing them. Either of us can call off the transactions if:

. the General Re or Berkshire stockholders fail to approve the Transactions;

. the Transactions have not been consummated by June 1, 1999;

. any government or court issues an order or takes another action enjoining or prohibiting one or both of the Mergers or the Transactions, and such action has become final and non-appealable; or

. the other party fails to perform its material obligations under the Merger Agreement, and such failure is not cured.

In addition, Berkshire may call off the transactions if:

. the General Re Board withdraws or adversely modifies its approval or recommendation of the Merger Agreement or the Transactions;

. the General Re Board recommends a transaction other than the Transactions with Berkshire; or

. General Re holds extended discussions or provides information to a third party for a transaction that the General Re Board has determined is superior to the Transactions or a third party proposes or commences a transaction and General Re does not timely reject such proposal.

General Re may call off the transactions in order to concurrently enter into an agreement with a third party for a proposal, made before stockholders' approval of the merger, that the General Re Board determines is superior to the Transactions.

TERMINATION FEE (PAGE 54)

If General Re terminates the merger agreement to enter into an agreement with another party, or if the General Re Board takes any action to make the General Re Rights Plan inapplicable to another party, then General Re must pay Berkshire a termination fee of $400 million and must reimburse Berkshire's expenses. The Merger Agreement requires General Re to pay to Berkshire, in certain circumstances, a termination fee of $400 million and reimbursement of Berkshire's expenses if Berkshire terminates the Merger Agreement.

STOCK OPTION AGREEMENT (PAGE 32)

We have entered into a Stock Option Agreement that permits Berkshire under certain circumstances to purchase 15,000,000 shares of General Re Common Stock, approximately 19.8% of the outstanding General Re Common Stock, at a price of $283.71 per share. Berkshire's total profit from the termination fee under the Merger Agreement and its profit under the Stock Option Agreement may not exceed $600 million.

APPRAISAL RIGHTS (PAGE 44)

Both of our companies are organized under Delaware law. Under Delaware law, Berkshire and General Re stockholders have no right to an appraisal of the value of their shares in connection with the Transactions. However, in the event of the Alternative Transaction, General Re stockholders who follow the procedures required by Delaware law and who have not voted in favor of the Transactions will be entitled to have their shares of General Re Common Stock appraised by a Delaware court and to receive "fair value" for such shares.

OPINION OF GENERAL RE'S FINANCIAL ADVISOR (PAGE 25)

In deciding to approve the Transactions, the General Re Board considered an opinion from its financial advisor, Goldman, Sachs & Co. ("Goldman Sachs"), as to the fairness of the Merger Consideration to be received by the holders of General Re Common Stock in the Transactions from a financial point of view. This opinion is attached as Annex IV to this Joint Proxy Statement/Prospectus. We encourage you to read and consider this opinion carefully, as well as the information under "The Transactions--Opinion of General Re's Financial Advisor."

FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE (PAGE 45)

We have each made forward-looking statements in this document (and in documents that are incorporated by reference) that are subject to risks and uncertainties. Forward-looking statements include the information concerning possible or assumed future results of operations of Berkshire, General Re or the combined companies. Also, when we use words such as "believes," "expects," "anticipates," "intends," "plans," "estimates" or similar expressions, we are making forward-looking statements. Stockholders should note that actual events and results may differ materially from those expressed in forward-looking statements due to a number of factors including, changes in market prices of Berkshire's significant investees, the occurrence of one or more catastrophic events that causes losses insured by General Re or the Berkshire insurance group, changes in insurance laws or regulations, changes in Federal income tax laws and general economic and market factors.

(1) This information has been developed under the assumption that the Alternative Transaction will not be consumated. Therefore, upon consummation of the General Re Merger, each outstanding share of General Re Common Stock will be converted into the right to receive either 0.0035 Class A shares or 0.105 Class B shares of New Berkshire Common Stock. The pro forma combined condensed financial statements assume that all General Re shares were converted into Class A shares at the fixed exchange ratio of 0.0035.

(2) Class B Common Stock has economic rights equal to one thirtieth ( 1/30) of the economic rights of Class A Common Stock. Earnings per share and book value per share are reflected on the equivalent Class A Common Stock basis. The equivalent Class B amounts are equal to one thirtieth of such amounts.

14

CERTAIN RISK FACTORS AND INVESTMENT CONSIDERATIONS

In considering whether to approve and adopt the Merger Agreement, and in making an election between Class A Common Stock and Class B Common Stock as the Merger Consideration, the stockholders of General Re should consider the following:

FIXED MERGER CONSIDERATION DESPITE POTENTIAL CHANGE IN RELATIVE STOCK PRICES. Upon completion of the General Re Merger, each share of General Re Common stock will be converted into the right to receive 0.0035 of a share of New Berkshire Class A Common Stock or 0.105 of a share of New Berkshire Class B Common Stock (plus cash for fractional shares) or, if the Alternative General Re Merger occurs, into 0.003395 of a share of Berkshire Class A Common Stock or 0.10185 of a share of Berkshire Class B Common Stock (plus cash). These exchange ratios will not be adjusted despite any increase or decrease in the price of either Berkshire or General Re Common Stock. The prices of Berkshire and General Re Common Stock when the Mergers occur may vary from their prices at the date of this Joint Proxy Statement/Prospectus and at the date of the Special Meetings. For example, during the twelve month period ending on August 11, 1998 (the most recent practicable date prior to the first mailing of this Joint Proxy Statement/ Prospectus), the closing price of Berkshire Class A Common Stock varied from a low of $41,500 to a high of $80,900 and ended that period at $68,900, and the closing price of General Re Common Stock varied from a low of $193 3/16 to a high of $259 11/16 and ended that period at $233 1/16 (see "Comparative Market Prices and Dividend Information" for further information). Such variations may be the result of changes in the business or operations of Berkshire or General Re or the prospects of their businesses, separately or combined, changes in market assessments of Berkshire or General Re's business, operations, or prospects, or in market assessments of the likelihood that the Mergers will be consummated, the tax effects of the Mergers, and the timing thereof, as well as general market and economic conditions and other factors. At the time of the Special Meetings, the holders of General Re shares will not know the exact value of the shares that they will receive when the General Re Merger is completed. Also, because Berkshire Common Stock is not included in the S&P 500 and General Re Common Stock will cease to be included in the S&P 500 index due to the Transactions, index funds and other institutional investors whose portfolios track that index may sell New Berkshire (or Berkshire) Common Stock that they receive in the Merger and may sell General Re Common Stock that they own prior to the Merger. Such selling may cause downward pressure on the stock market prices of New Berkshire (or Berkshire) Common Stock and General Re Common Stock.

Both Berkshire and General Re stockholders are urged to obtain current market quotations for Berkshire and General Re Common Stock.

POTENTIAL FOR TAXATION OF MERGER CONSIDERATION TO STOCKHOLDERS OF GENERAL RE. Berkshire and General Re are seeking certain tax rulings from the IRS. If the requested rulings are denied or are not obtained prior to February 19, 1999, Berkshire has the right to elect to proceed with the Alternative Transaction, in which event the excess of the market value of the Merger Consideration received by a stockholder over the tax basis in such stockholder's shares of General Re Common Stock will be a taxable gain to such holder. However, the Merger Consideration will not be increased in such event, even though holders of General Re Common Stock may be required to pay additional Federal income taxes as a result of the Alternative Transaction. See "The Transactions--The Alternative Transaction" and "The Transactions-- Federal Income Tax Considerations."

NONCONVERTIBILITY, MARKET PRICE AND LESSER VOTE OF NEW BERKSHIRE CLASS B COMMON STOCK. Each share of New Berkshire Class A Common Stock is convertible into 30 shares of New Berkshire Class B Common Stock, but shares of New Berkshire Class B Common Stock are not convertible into shares of New Berkshire Class A Common Stock or any other security. Although a share of New Berkshire Class B Common Stock may sell below one-thirtieth of the market price for New Berkshire Class A Common Stock, it is unlikely that a share of New Berkshire Class B Common Stock will sell more than fractionally above one- thirtieth of the market price for New Berkshire Class A Common Stock because higher prices than that would cause arbitrage activity to ensue. Also, holders of shares of New Berkshire Class A Common Stock will be entitled to one vote, but holders of shares of New Berkshire Class B Common Stock will be entitled to only one two-hundredth ( 1/200th) of a vote, for each share on matters submitted to a vote of New Berkshire stockholders. See "Description of New Berkshire Capital Stock." The foregoing applies equally to Berkshire's Class A and Class B Common Stock.

15

PAST GROWTH RATE IN BERKSHIRE'S BOOK VALUE PER SHARE IS NOT AN INDICATION OF FUTURE RESULTS. In the years since Berkshire's present management acquired control of Berkshire, its book value per share has grown at a highly satisfactory rate. Because of the large size of Berkshire's capital base (approximately $36.9 billion as of June 30, 1998, and New Berkshire's pro forma stockholder's equity at that date would have been $58.0 billion), Berkshire's book value per share cannot increase in the future at a rate even close to its past rate.

DEPENDENCE ON KEY MANAGEMENT. Investment decisions and all other capital allocation decisions are made for Berkshire's businesses by Mr. Buffett, its Chairman, age 67, in consultation with Mr. Munger, its Vice Chairman, age 74. If for any reason the services of Berkshire's key management personnel, particularly Mr. Buffett, were to become unavailable, there could be a material adverse effect both on New Berkshire and on the market price of New Berkshire Common Stock.

SUPER-CAT INSURANCE. Berkshire believes that in recent years it has been the largest writer in the world of "super-cat" insurance, whereby reinsurers (such as Berkshire) assume a risk of large losses from mega-catastrophes such as hurricanes or earthquakes. This business has produced pre-tax underwriting gains of approximately $283 million, $167 million and $152 million in 1997, 1996 and 1995, respectively, but is virtually certain to produce huge losses in some years in the future. Berkshire's present underwriting standards (which are subject to change) seek to limit Berkshire's exposure to a loss from a single event to $1 billion in excess of the premium earned. Prices have fallen in the super-cat business and Berkshire's volume in this line of business may significantly decline.

CONCENTRATION OF INVESTMENTS. Compared to other insurers, Berkshire's insurance subsidiaries keep an unusually high percentage of their assets in common stocks and diversify their portfolios far less than is conventional. A significant decline in the general stock market would produce a large decrease in Berkshire's book value, one far greater than likely to be experienced by most other property-casualty insurance companies. Such a decrease could have a material adverse effect on the share price for Berkshire Common Stock, but would not be a basis for termination of the Merger Agreement by General Re.

ABSENCE OF STOCKHOLDER-DESIGNATED CONTRIBUTIONS PROGRAM FOR NEW BERKSHIRE CLASS B STOCK. For some years Berkshire has let its stockholders of record of Berkshire Class A Stock designate charitable contributions to be made by Berkshire. In 1997, stockholders of record as of August 31, 1997 were entitled to designate $16 per share, an amount that is expected to increase in the future. New Berkshire will continue this program for stockholders of record of New Berkshire Class A Stock. However, shares of Berkshire Class B Common Stock are not eligible to participate in the program. Accordingly, General Re stockholders who receive shares of New Berkshire Class B Common Stock will not participate in the program with respect to their shares of New Berkshire Class B Common Stock.

ACCOUNTING CHARGE FOR COMPENSATION. General Re's reported expenses (but not its true economic expenses) will increase after the merger due to changes in its compensation plans. As part of its current compensation plans, General Re grants options on its shares to many of its employees. As discussed elsewhere in this Joint Proxy Statement/Prospectus, such options will be replaced with a new long-term incentive compensation plan having a cash value equal to General Re's option plan. Under current accounting rules, General Re excludes the economic costs related to the granting of stock options from reported earnings. The costs of the new long-term incentive compensation plan, however, will be charged as an expense against the combined companies' consolidated earnings.

DECLINE IN PREMIUM VOLUME. General Re has recently been experiencing a decline in written premiums from its North American property/casualty operations. The decline in premium volume reflects the current competitive market and General Re's adherence to underwriting discipline. Over time, should this trend of declining premiums continue, General Re will experience a reduction in float which will create a decrease in invested assets and related investment income.

At the Special Meetings, holders of Berkshire Common Stock and General Re Voting Stock will be asked to vote upon a proposal to approve and adopt (i) the Agreement and Plan of Mergers, dated as of June 19, 1998, between Berkshire and General Re (the "Merger Agreement"), which provides, among other things, that Berkshire and General Re will each merge with separate subsidiaries of NBH, Inc., a Delaware corporation ("New Berkshire") to be renamed "Berkshire Hathaway Inc." following the consummation of the Mergers (as defined) and which gives Berkshire the right to elect the Alternative Transaction under certain circumstances, (ii) in the case of the Berkshire Meeting, the Merger Agreement ("Berkshire Merger Agreement"), among Berkshire, New Berkshire and Wyllis Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of New Berkshire ("Merger Sub A"), which provides for the merger of Merger Sub A with and into Berkshire (the "Berkshire Merger"), and a proposal to amend the Restated Certificate of Incorporation of Berkshire to increase to 1,650,000 (from 1,500,000) the number of shares of Berkshire Class A Common Stock, and to increase to 55,000,000 (from 50,000,000) the number of shares of Berkshire Class B Common Stock, authorized for issuance (the "Charter Amendment"), which will be effected in the event of the Alternative Transaction, and (iii) in the case of the General Re Meeting, the Merger Agreement (the "General Re Merger Agreement" and, together with the Berkshire Merger Agreement, the "Subsidiary Merger Agreements"), among General Re, New Berkshire and Steven Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of New Berkshire ("Merger Sub B"), which provides for the merger of Merger Sub B with and into General Re (the "General Re Merger" and, together with the Berkshire Merger, the "Mergers") and, in the alternative, a Merger Agreement (the "Alternative General Re Merger Agreement") among General Re, Berkshire and one or more subsidiaries of Berkshire, which provides for the merger of an indirect subsidiary of Berkshire with and into General Re (the "Alternative General Re Merger"). The transactions contemplated by the Merger Agreement, the Subsidiary Merger Agreements, and the Alternative General Re Merger Agreement, including the Alternative Transaction (see "The Transactions--The Alternative Transaction"), are referred to herein as the "Transactions." As a result of the Mergers, each of Berkshire and General Re will become a wholly owned subsidiary of New Berkshire.

The terms, designations, preferences, limitations, privileges and rights of the respective classes of New Berkshire Common Stock will be identical to those of the existing corresponding classes of Berkshire Common Stock.

BACKGROUND OF THE TRANSACTIONS

For many years, the Berkshire Hathaway Insurance Group and General Re have engaged in reinsurance transactions with each other. In September 1996, Ajit Jain, a senior officer of the Berkshire Hathaway Insurance Group, and Joseph P. Brandon, Chief Financial Officer of General Re, whose offices are both in Stamford, Connecticut, met there to discuss the possibilities for a strategic alliance or other arrangement enabling the Berkshire Hathaway Insurance Group and General Re to pursue reinsurance opportunities together. Mr. Jain discussed this topic with Warren E. Buffett, Chairman and Chief Executive Officer of Berkshire, who knew General Re's business well and was professionally acquainted with Ronald E. Ferguson, Chairman and Chief Executive Officer of General Re. Mr. Buffett told Mr. Jain, who conveyed to Mr. Brandon, that he was willing to consider a merger of General Re with Berkshire, but no merger discussions ensued at that time.

Almost a year later, in July of 1997, Mr. Jain and Mr. Brandon reinitiated their discussions. Later in July 1997, Mr. Buffett and Mr. Ferguson met. At that meeting and during subsequent meetings and telephone conversations in August and September 1997, they discussed their respective reinsurance businesses and the strategic implications to Berkshire and General Re of a possible business combination. Mr. Buffett and Mr. Ferguson shared the view that a combination of Berkshire and General Re would benefit both companies for the reasons described below under "The Transactions--Reasons for the Transactions; Recommendations of the Boards of Directors." In addition, Mr. Buffett concluded that he would be delighted to work closely with Mr. Ferguson and would welcome his participation as a member of Berkshire's Board of Directors. Mr. Buffett also said that any tax-free merger would depend upon Berkshire being fully satisfied that the transaction would also not result in any taxes upon Berkshire or its stockholders. In connection with these preliminary discussions, General Re engaged Goldman Sachs as its financial advisor and consulted with Wachtell, Lipton, Rosen & Katz, its legal counsel. During this period, the relationship between the market prices of Berkshire's Common Stock and General Re's Common Stock was such that Mr. Buffett was not willing to consider a transaction that would provide any premium to the General Re stockholders. Accordingly, neither Mr. Buffett nor Mr. Ferguson proposed a share exchange ratio, and these discussions were not pursued beyond these preliminary matters.

In December of 1997 and April of 1998, Messrs. Jain and Brandon engaged in further discussions, by telephone and in person, regarding the possibility of a business combination between Berkshire and General Re. Thereafter, on May 6, 1998, Messrs. Buffett and Ferguson met in New York City at Mr. Buffett's invitation to discuss further the possibility of a business combination between the two companies, including the potential financial and other terms of such a combination. Mr. Buffett had studied General Re's most recent annual report and continued to believe that a merger would enhance the value of both companies. Since the prior meetings, the value of Berkshire's stock had increased in relationship to the value of General Re's Common Stock. As a result, at the May 6, 1998 meeting, Mr. Buffett proposed an exchange ratio of 0.105 of a share of Berkshire Class B Common Stock for each share of General Re Common Stock, subject to negotiation of other definitive terms of a combination and to review and approval by their respective companies' boards of directors.

Mr. Buffett and Mr. Ferguson met again on May 27, 1998 and also discussed the subject during a June 5, 1998 phone conversation. During these discussions, Mr. Buffett and Mr. Ferguson continued to discuss the terms of a potential business combination, including the exchange ratio. As a part of these discussions, Mr. Ferguson

18

also explained to Mr. Buffett the various employee benefit and incentive plans in place at General Re and the need to restructure certain of those plans if a combination occurred. They also discussed transaction structure, and Mr. Buffett said that he would agree to vote his shares in Berkshire in favor of the Merger Agreement. As a result of these discussions, Mr. Buffett and Mr. Ferguson reached an agreement between them, subject to board review and approval, on a proposal to combine their companies at the proposed share exchange ratio, using the desired new holding company structure if the IRS would issue the requested tax rulings. Mr. Buffett and Mr. Ferguson continued to discuss various terms of the business combination until the General Re Board meeting.

On June 10, 1998, the General Re Board of Directors met and discussed the proposed business combination. General Re's legal advisors were present at the meeting and participated in the discussions. Following the discussions, the General Re Board authorized management to continue discussions with Berkshire regarding a possible business combination, including negotiation of definitive terms.

At the conclusion of the General Re Board of Directors meeting, Mr. Ferguson telephoned Mr. Buffett to inform him that the General Re Board was favorably inclined toward the merger proposal and, based upon such favorable inclination, had asked Goldman Sachs to undertake an analysis of the financial implications of a possible business combination between Berkshire and General Re and the impact thereof on the shareholders of General Re.

Between June 10 and June 18, 1998, Messrs. Ferguson and Brandon, with the assistance of General Re's outside financial and legal advisors, negotiated the terms of the Merger Agreement, Stock Option Agreement and Voting Agreements with representatives of Berkshire and its legal counsel. During the course of those negotiations, General Re requested, and Berkshire agreed, that the Merger Agreement allow General Re stockholders the election to receive either New Berkshire Class A Common Stock or New Berkshire Class B Common Stock. The exchange ratio of 0.0035 of a share of New Berkshire Class A Common Stock reflects the fact that New Berkshire Class B Common Stock will have one- thirtieth of the economic rights of one share of New Berkshire Class A Common Stock (which is the relationship between the current Berkshire Class A and Class B Common Stock). Berkshire, General Re and their respective legal counsel also negotiated the terms of the Alternative Transaction in the event that the IRS will not issue the requested rulings. General Re requested that Charles T. Munger, Vice-Chairman of Berkshire, also agree to vote his shares in Berkshire in favor of the Merger Agreement, and Mr. Munger agreed to do so. During this time, the parties and their legal counsel jointly began drafting the private letter ruling request to be submitted to the IRS. During this period, representatives of General Re also conducted a due diligence review of Berkshire.

The General Re Board of Directors met again on June 18 and 19, 1998, at which meetings Mr. Ferguson, together with Mr. Brandon, discussed the process leading to the proposed business combination being presented to the General Re Board for approval, presented management's analysis of the financial and other terms of the proposed business combination with Berkshire and reviewed the results of General Re's due diligence review. Goldman Sachs made a presentation as to the financial aspects of the proposed transaction and General Re's legal counsel reviewed for the General Re Board its fiduciary obligations and made a presentation as to the terms of the Merger Agreement, Stock Option Agreement and other documents relating to the transaction. At the Board's invitation, Mr. Buffett and Mr. Munger attended a portion of the June 19, 1998 meeting. Mr. Buffett and Mr. Munger discussed management succession at Berkshire, Berkshire's operational philosophy and opportunities for General Re as a part of Berkshire. Also during that meeting, Goldman Sachs delivered its oral opinion to the effect that, as of June 19, 1998 and based upon the qualifications and assumptions made and matters considered by Goldman Sachs described in its written opinion dated June 19, 1998, the Merger Consideration to be received in the Transactions by holders of General Re Common Stock is fair from a financial point of view to such holders. At the conclusion of the meeting, the General Re Board of Directors determined that the Merger Agreement and the transactions contemplated thereby, including the Stock Option Agreement and the transactions contemplated in it, are fair to and in the best interests of General Re and its stockholders. Accordingly, the General Re Board of Directors approved the Merger Agreement and the Stock Option Agreement and resolved to recommend that the General Re stockholders approve the Merger Agreement, the General Re Merger, and the other contemplated transactions.

19

The Berkshire Board of Directors met later on June 19, 1998 and determined that the Merger Agreement and the transactions contemplated thereby, including the Stock Option Agreement and the transactions contemplated in it, are fair to and in the best interests of Berkshire and its stockholders. Accordingly, the Berkshire Board of Directors approved the Merger Agreement and the Stock Option Agreement and resolved to recommend that the Berkshire stockholders approve the Merger Agreement, the Berkshire Merger, and the other contemplated transactions.

The Merger Agreement, Stock Option Agreement, and Voting Agreements were signed and a joint press release was issued shortly after the close of trading on the New York Stock Exchange (the "NYSE") on June 19, 1998.

REASONS FOR THE TRANSACTIONS; RECOMMENDATIONS OF THE BOARDS OF DIRECTORS

Berkshire and General Re believe that their combination will create value for both companies' stockholders by providing opportunities to achieve substantial benefits that would not be available to either company alone. Specifically, the combination allows for substantial synergy in four identified areas.

First, the combination will remove constraints on earnings volatility that have caused General Re in the past to decline certain attractive reinsurance business and to retrocede to other reinsurers substantial amounts of the business that General Re has written. General Re has been unable to operate in a manner that could produce large swings in its reported earnings, due both to its status as a publicly traded company and its desire to maintain its triple- A credit rating. On occasion, that constraint has required General Re to forego opportunities to write large, complex, but attractive, reinsurance business. As part of Berkshire, that constraint will disappear. Berkshire is willing to accept reinsurance business that can produce extreme volatility in reported periodic results. Accounting consequences do not influence decisions of Berkshire's management with respect to this or any other Berkshire business. This fact, along with Berkshire's extraordinary financial strength, are believed to be the primary reasons why the Berkshire Hathaway Insurance Group has become a major provider of large and complex reinsurance coverages. Although General Re will operate independently of Berkshire's other insurance and reinsurance operations, it will similarly operate free of constraints on earnings volatility.

Two benefits are expected from removing those constraints. One, General Re's long-term profitability should be enhanced because it can accept attractive business it previously declined. Two, General Re will be free to reduce its reliance on the retrocessional market (i.e. reinsurance of reinsurance) over time. Reduced retrocessions will increase General Re's investable funds ("float").

Second, General Re has substantial opportunities to develop its global reinsurance franchise. After the combination, General Re will be able to make investments to grow its international business as quickly as it sees fit. Berkshire seeks growth in the long-term intrinsic value of its businesses, and is willing to incur short-term costs in doing so, without regard to periodic reported earnings.

Third, General Re will gain tax flexibility from the combination. In managing insurance investments, it is a distinct advantage to know that large amounts of taxable income will consistently recur. Most insurance companies are unable to assume the consistent recurrence of significant taxable income. Berkshire insurance companies can make this assumption confidently, due to the large and diverse streams of taxable income flowing from Berkshire's numerous noninsurance subsidiaries. Accordingly, General Re after the combination can fashion its investment strategy without concern as to the presence of taxable income.

Finally, Berkshire's insurance companies, including General Re after the combination, are backed by abundant capital. The Berkshire Hathaway Insurance Group maintains capital strength at high levels, significantly higher than normal in the industry. This capital strength differentiates Berkshire insurance companies from their competitors. Berkshire's capital strength will allow General Re to follow whatever asset strategy makes the most sense, unconstrained by the effects on its capital of a sharp market decline. Periodically, this flexibility has proven of enormous advantage to Berkshire's insurance companies, and should lead over the long term to increased returns generated on General Re's invested assets over what they otherwise would be.

20

In addition to these synergies, the combination will add approximately $25 billion to Berkshire's invested insurance assets.

The Boards of Directors of each company also considered various other factors that contributed to their approval and recommendation of the Merger Agreement and the Transactions. Those factors include: (i) the terms and conditions of the Merger Agreement, including an exchange ratio that provides certainty about the number of shares to be issued and received in the Mergers;
(ii) the expected, although not certain, treatment of the Mergers as tax-free exchanges of stock; and (iii) the certainty of consummation of the combination even if the IRS does not issue the private letter rulings that the companies have requested.

The Berkshire Board also considered the advantages of adding Mr. Ferguson as a director and the certainty provided by the Merger Agreement that Berkshire will not be obligated to consummate the Berkshire Merger unless Berkshire is fully satisfied that the transaction will not result in any taxes upon Berkshire or its stockholders.

The General Re Board also considered a number of other items and factors, including, without limitation, the following:

(i) the financial presentation of Goldman Sachs to the General Re Board and the oral opinion of Goldman Sachs to the effect that, as of June 19, 1998 and based upon the qualifications and assumptions made and matters considered by Goldman Sachs described in its written opinion dated June 19, 1998, the Merger Consideration to be received by the stockholders of General Re in the Transactions is fair to such stockholders from a financial point of view;

(ii) General Re's business, management, financial performance and condition, strategic objectives, prospects and competitive position, and the recommendations of General Re's management;

(iii) a review of strategic alternatives, including other possible business combinations and, based on the foregoing, the belief that a transaction with another company could not reasonably be expected to offer terms with advantages comparable to those of a business combination with Berkshire;

(iv) the fact that the Merger Consideration on a per share basis represented a premium over recently prevailing market prices of General Re Common Stock;

(v) the ability of the stockholders of General Re who wish to do so to continue to participate in General Re's business as part of Berkshire after the Mergers and to benefit from the potential appreciation of the common stock of Berkshire; however, the General Re Board noted that because of the large size of Berkshire's capital base, Berkshire's book value is not expected to increase in the future at its historical rate;

(vi) its knowledge and review of the financial condition, results of operations and business prospects of Berkshire, as well as the results of General Re's due diligence review of Berkshire, and its belief that Berkshire's historical practice has been to retain management and allow the companies to operate autonomously, and that consequently the Mergers would not be likely to adversely affect General Re's relationships with its clients and associates;

(vii) the terms and conditions of the Merger Agreement and the parties respective representations, warranties, covenants, agreements and conditions to their respective obligations, including the condition that the Mergers be approved by the General Re Voting Stockholders; and

(viii) the risk that benefits sought in the Mergers would not be obtained, the risk that the Mergers would not be consummated, the fact that, with a fixed exchange ratio, the relative values of Berkshire and General Re are fixed by the parties in advance and would not take into account subsequent changes or changed market perceptions, and the effect of the public announcement of the Mergers on the trading price of the common stock of the parties.

The General Re Board also considered the factors set forth in the section entitled "Certain Risk Factors and Other Investment Considerations."

21

Each company's Board determined that the potential advantages of the Transactions far outweigh the disadvantages. Each company's Board believes that the Transactions will result in its company's stockholders realizing greater value than its company could deliver to them alone. Based on the consideration of these and other relevant matters, each company's Board unanimously determined that the Merger Agreement and the Mergers, and the other Transactions, are in the best interests of its company and its company's stockholders.

The foregoing discussion of the factors considered by each company's Board is not intended to be exhaustive, but is believed to include all material factors considered by each company's Board. In reaching its decision to approve the Merger Agreement and the Mergers, neither company's Board quantified or assigned any relative weights to the factors considered, or considered any one factor to be determinative, and individual directors may have given different weight to different matters.

THE BERKSHIRE BOARD OF DIRECTORS AND THE GENERAL RE BOARD OF DIRECTORS HAVE EACH UNANIMOUSLY CONCLUDED THAT THE MERGERS ARE IN THE BEST INTERESTS OF THEIR RESPECTIVE STOCKHOLDERS, AND EACH UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS

VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE TRANSACTIONS. SEE "THE TRANSACTIONS--CONFLICTS OF INTEREST" AND "THE TRANSACTIONS--OTHER AGREEMENTS AND TRANSACTIONS."

FORM OF THE MERGERS

If the approval of the holders of Berkshire Common Stock is obtained and all other conditions to the Berkshire Merger are satisfied or waived, pursuant to the Berkshire Merger Agreement (a copy of which is attached as Annex V to this Agreement) Merger Sub A will be merged with and into Berkshire, with Berkshire being the surviving corporation after the Berkshire Merger and a wholly owned subsidiary of New Berkshire. If the approval of the holders of General Re Voting Stock is obtained and all other conditions to the General Re Merger are satisfied or waived, pursuant to the General Re Merger Agreement (a copy of which is attached as Annex VI to this Agreement) Merger Sub B will be merged with and into General Re, with General Re being the surviving corporation after the General Re Merger and a wholly owned subsidiary of New Berkshire. After the Berkshire Merger, Berkshire will change its name to "OBH, Inc." and New Berkshire will change its name to "Berkshire Hathaway Inc." The date on which the closing of the Mergers occurs is referred to herein as the "Closing Date."

THE ALTERNATIVE TRANSACTION

The Merger Agreement gives Berkshire the right to elect an alternative form of transaction (the "Alternative Transaction") if the IRS refuses to grant tax rulings requested by the companies or does not do so prior to February 19, 1999. This section of the Joint Proxy Statement/Prospectus describes the Alternative Transaction and the events that may cause the parties to consummate the Alternative Transaction. If the Alternative Transaction occurs, each holder of General Re Common Stock will recognize gain or loss equal to the difference between (i) the sum of the fair market value of the shares of Berkshire Common Stock and the amount of cash received by such holder and (ii) such holder's tax basis in its shares of General Re Common Stock. For a further explanation of the tax consequences of the Alternative Transaction, see "The Transactions--Federal Income Tax Considerations."

On June 29, 1998, Berkshire and General Re filed a joint private letter ruling request (the "Ruling Request") with the IRS. Each company agreed in the Merger Agreement to use its reasonable best efforts to obtain three specified rulings (the "Rulings") as soon as practicable. The three requested Rulings specified in the Merger Agreement are as follows:

(i) The "351(e) Ruling": The companies requested that the IRS rule that New Berkshire will not be an "investment company" within the meaning of
Section 351(e) of the Internal Revenue Code of 1986, as amended (the "Code").

(ii) The "No Gain or Loss Ruling": The companies also requested that the IRS rule that, if the Mergers qualify as an exchange under Section 351 of the Code, no gain or loss will be recognized by New

22

Berkshire or by the stockholders of Berkshire or General Re, including by application of certain provisions of Section 368 of the Code, upon the exchange of Berkshire Common Stock or General Re Common Stock for New Berkshire Common Stock pursuant to the Mergers, except that gain realized by holders of General Re Common Stock will be recognized to the extent of any cash received in lieu of a fractional share interest in New Berkshire Class B Common Stock.

(iii) The "368(c) Ruling": The companies also requested that the IRS rule that New Berkshire will neither acquire "control" of Berkshire or General Re in the Mergers nor have "control" of Berkshire or General Re immediately after the Mergers, in both cases within the meaning of Section 368(c) of the Code.

The purpose of the Ruling Request is to provide assurance that the Mergers of Berkshire and General Re with subsidiaries of New Berkshire will not result in unintended, adverse tax consequences to New Berkshire or its stockholders. If New Berkshire were an investment company within the meaning of Section
351(e), adverse tax consequences to New Berkshire and its stockholders could follow. Certain proposed Treasury regulations (the "Proposed Regulations") could suggest, under certain circumstances, that New Berkshire might be such an investment company. The Proposed Regulations were proposed in 1981 and have never been adopted in final form, but they purport to apply to transactions occurring after February 17, 1976. The 351(e) Ruling is intended to provide assurance that the Proposed Regulations, even if adopted, will not result in such adverse tax consequences.

The No Gain or Loss Ruling and the 368(c) Ruling are intended to provide assurance that, if the Mergers qualify as tax-free exchanges under Section 351 of the Code, the Mergers will not result in unintended, adverse tax consequences under certain provisions of Section 368 of the Code. Assuming that the Rulings are issued, the companies' respective obligations to consummate the Mergers are conditioned upon their receipt from their tax counsel of legal opinions, based upon reasonably requested representation letters and dated the Closing Date, that the Mergers will be treated as a transfer of property to New Berkshire by the companies' respective stockholders governed by Section 351 of the Code. For a discussion of the tax consequences of the Mergers qualifying as exchanges under Section 351 of the Code, see "The Transactions--Federal Income Considerations."

As of the date of this Proxy Statement/Prospectus, the IRS has neither granted nor denied any of the three Rulings.

In general, Berkshire may elect to proceed with the Alternative Transaction (the "Alternative Election") if the IRS informs Berkshire that it will not grant the 351(e) Ruling. However, it is possible that the United States Treasury Department (the "Treasury Department") may withdraw or announce its intention to withdraw the Proposed Regulations that prompted the 351(e) Ruling request. If the IRS will not grant the 351(e) Ruling because the Treasury Department has withdrawn or announced its intention to withdraw the Proposed Regulations, then Berkshire may elect to proceed with the Alternative Transaction only if the IRS also informs Berkshire that it will not grant the
368(c) Ruling. Also, Berkshire may elect to proceed with the Alternative Transaction if the IRS neither grants nor denies the requested Rulings by February 19, 1999. Berkshire may make the election by giving written notice to General Re within 10 business days after the earlier of its being so informed by the IRS or February 19, 1999. In the event Berkshire is entitled to make the Alternative Election and does not give any written, timely notice to General Re declining to make the Alternative Election, Berkshire will be deemed to have made the Alternative Election, and the Alternative Transaction will occur, subject to the conditions contained in the Merger Agreement.

Berkshire cannot make the Alternative Election if it has received notice that the IRS has issued the 351(e) Ruling and the No Gain or Loss Ruling. If the Treasury Department has withdrawn or announced its intention to withdraw the Proposed Regulations that prompted the 351(e) Ruling request, Berkshire cannot make the Alternative Election if it has received notice that the IRS has issued either the No Gain or Loss Ruling or the 368(c) Ruling on or prior to the date Berkshire elects to proceed with the Alternative Transaction.

23

If Berkshire makes or is deemed to make the Alternative Election, then the Alternative Transaction will be consummated, subject to the conditions contained in the Merger Agreement. In that event, the Alternative General Re Merger will occur and the Berkshire Merger will not occur. More specifically, General Re will merge with, and will become, an indirect wholly owned subsidiary of Berkshire itself rather than New Berkshire. As a result of that merger, holders of General Re Common Stock will receive a combination of Berkshire Common Stock (rather than New Berkshire Common Stock) and cash. Berkshire itself will not merge with a New Berkshire subsidiary or any other entity. Accordingly, Berkshire will remain as the ultimate holding company of its businesses, including, after the merger, General Re. Each share of General Re Common Stock will be converted into the right to receive, at the option of the holder, either (A) 0.003395 of a share of Berkshire Class A Common Stock and an amount of cash equal to 0.000105 times the Average Trading Price (as defined in "The Transactions--Merger Consideration") of a share of Berkshire Class A Common Stock or (B) 0.10185 of a share of Berkshire Class B Common Stock and an amount of cash equal to 0.00315 times the Average Trading Price of a share of Berkshire Class B Common Stock. The Berkshire Common Stock received by General Re stockholders will have identical rights and privileges as the New Berkshire Common Stock that General Re stockholders would have received. The existing Berkshire Common Stock held by Berkshire stockholders will remain outstanding and be unchanged.

If the Alternative Transaction occurs, certain other aspects of the Transactions will also be adjusted. Specifically, because the Berkshire Merger will not occur, there will be no effect on the any existing Berkshire stock options. Also, Mr. Ferguson will be appointed to the Berkshire Board (rather than the New Berkshire Board). Wherever appropriate, the rights and obligations of New Berkshire under the Merger Agreement will become rights and obligations of Berkshire.

Neither the failure to receive one or more of the Rulings nor the making of the Alternative Election constitutes a basis for either party to refuse to consummate the Transactions.

MERGER CONSIDERATION

General Re. Except for the payment of cash in lieu of fractional shares or as stated otherwise in the event of the Alternative Transaction, at the Effective Time, each issued and outstanding share of General Re Common Stock (other than shares owned by General Re, Berkshire, or their respective subsidiaries) will be converted into the right to receive from New Berkshire either (a) 0.0035 of a share of New Berkshire Class A Common Stock or (b) 0.105 of a share of New Berkshire Class B Common Stock (the "New Berkshire Merger Consideration"), at the option of the holder.

Notwithstanding the foregoing, in the event of the Alternative Transaction, at the Effective Time, each issued and outstanding share of General Re Common Stock (other than shares owned by General Re, Berkshire or their respective subsidiaries and shares of holders who have properly exercised appraisal rights under the DGCL) will be converted into the right to receive from Berkshire either (a) 0.003395 of a share of Berkshire Class A Common Stock plus an amount in cash equal to the product of 0.000105 and the Average Trading Price of one share of Berkshire Class A Common Stock or (b) 0.10185 of a share of Berkshire Class B Common Stock plus an amount in cash equal to the product of 0.00315 and the Average Trading Price of one share of Berkshire Class B Common Stock (the "Alternative Merger Consideration" and, together with the New Berkshire Merger Consideration, the "Merger Consideration"), at the option of the holder. The "Average Trading Price" is the average of the high and low trading prices of Berkshire Class A Common Stock or Berkshire Class B Common Stock, as the case may be, as reported on the New York Stock Exchange Composite Tape for each of the five consecutive trading days ending on the last full trading day immediately prior to the date on which the Effective Time occurs. See "The Transactions--The Alternative Transactions" and "The Transactions--Federal Income Tax Considerations."

All outstanding shares of General Re Preferred Stock will be called for redemption and redeemed prior to the Effective Time. Therefore, prior to or concurrently with the Effective Time, holders of General Re Preferred Stock will have received the right to obtain the redemption price for their shares of General Re Preferred Stock,

24

or such holders will have become holders of General Re Common Stock by virtue of the exercise of their right to convert the General Re Preferred Stock. Upon such conversion, such holders will have the same rights to elect and receive Merger Consideration as the other holders of General Re Common Stock. See "The Transactions--Other Agreements and Transactions."

If prior to the Effective Time the outstanding shares of Berkshire Class A or Class B Common Stock have been changed into a different number of shares or a different class, due to any stock dividend, reclassification, recapitalization, split or similar transaction, the Merger Consideration will be correspondingly adjusted to the extent appropriate to reflect such changes.

Any shares of General Re Common Stock owned by General Re, Berkshire or any of their subsidiaries, will automatically be cancelled and retired at the Effective Time and will cease to exist, and no New Berkshire Common Stock, Berkshire Common Stock or other consideration will be delivered in exchange therefor.

Berkshire. Except for shares owned by Berkshire or any of its subsidiaries, at the Effective Time, without any action on the part of any Berkshire stockholder, each issued and outstanding share of Berkshire Class A Common Stock will be converted into one share of New Berkshire Class A Common Stock and each issued and outstanding share of Berkshire Class B Common Stock will be converted into one share of New Berkshire Class B Common Stock. In the event of the Alternative Transaction, the Berkshire Merger will not occur; therefore no conversion of Berkshire Common Stock will occur and the outstanding shares of Berkshire Class A and Class B Common Stock will remain outstanding and be unchanged. See "The Transactions--The Alternative Transaction."

OPINION OF GENERAL RE'S FINANCIAL ADVISOR

On June 19, 1998, Goldman Sachs rendered an oral opinion to the General Re Board (subsequently confirmed in writing to the General Re Board) to the effect that, as of such date and based upon the qualifications and assumptions made and matters considered by Goldman Sachs described in its written opinion dated June 19, 1998 (the "Goldman Sachs Opinion"), the Merger Consideration to be received in the Transactions by holders of shares of General Re Common Stock pursuant to the Merger Agreement is fair from a financial point of view to such holders.

THE FULL TEXT OF THE GOLDMAN SACHS OPINION, WHICH SETS FORTH THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED AND MATTERS CONSIDERED IN, AND THE LIMITATIONS ON, THE REVIEW UNDERTAKEN IN CONNECTION WITH THE GOLDMAN SACHS OPINION, IS ATTACHED HERETO AS ANNEX IV AND IS INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS OF GENERAL RE SHOULD READ THE GOLDMAN SACHS OPINION IN ITS ENTIRETY AND CONSIDER IT CAREFULLY. THE SUMMARY OF THE GOLDMAN SACHS OPINION SET FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE GOLDMAN SACHS OPINION. THE GOLDMAN SACHS OPINION IS ADDRESSED TO THE BOARD OF DIRECTORS OF GENERAL RE AND DOES NOT ADDRESS THE MERITS OF THE UNDERLYING DECISION OF GENERAL RE TO ENGAGE IN THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF GENERAL RE AS TO HOW SUCH STOCKHOLDER SHOULD VOTE WITH RESPECT TO ANY MATTER TO BE VOTED UPON AT THE GENERAL RE MEETING.

In connection with the Goldman Sachs Opinion, Goldman Sachs reviewed, among other things: the Merger Agreement; Annual Reports to Shareholders and Annual Reports on Form 10-K for the five years ended December 31, 1997 of General Re and Berkshire, certain interim reports to shareholders and Quarterly Reports on Form 10-Q of General Re and Berkshire; Statutory Annual Statements filed by certain insurance subsidiaries of General Re and Berkshire with the Insurance Departments of the States under the laws of which they are respectively organized for the five years ended December 31, 1997; certain interim statutory financial information

25

filed by such subsidiaries with such Insurance Departments; certain other communications from General Re and Berkshire to their respective shareholders; and certain internal financial analyses and forecasts for General Re prepared by its management. Goldman Sachs also held discussions with members of the senior management of General Re and Berkshire regarding the strategic, financial and operating rationale for, and expected benefits of, the transactions contemplated by the Merger Agreement and the past and current business operations, financial condition and future prospects of their respective companies. In addition, Goldman Sachs reviewed the reported price and trading activity for shares of General Re Common Stock and shares of Berkshire Common Stock, compared certain financial and stock market information for General Re and Berkshire with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the reinsurance industry specifically and in other industries generally and performed such other studies and analyses as Goldman Sachs considered appropriate.

In preparing the Goldman Sachs Opinion, Goldman Sachs relied upon the accuracy and completeness of all of the financial and other information reviewed by Goldman Sachs and assumed such accuracy and completeness for purposes of rendering its opinion. In addition, Goldman Sachs noted that they are not actuaries and that the services of Goldman Sachs did not include actuarial determinations or evaluations or an attempt to evaluate actuarial assumptions. In addition, Goldman Sachs noted that they did not make an independent evaluation or appraisal of the assets and liabilities (including the loss and loss adjustment expense reserves) of General Re or Berkshire or any of their subsidiaries and was not furnished with any such evaluation or appraisal. In that regard, Goldman Sachs made no analyses of, and expressed no opinion as to, the adequacy of the loss and loss adjustment expense reserves of General Re or Berkshire. Goldman Sachs noted that it was advised by the management of Berkshire that Berkshire does not prepare financial forecasts, and that Goldman Sachs' review of Berkshire was limited to publicly available information and discussions with the management of Berkshire. Goldman Sachs noted in the Goldman Sachs Opinion that it was not requested to, and did not, solicit from third parties indications of interest in acquiring all or part of General Re or in engaging in a business combination or any other strategic transaction with General Re.

Goldman Sachs was not requested to make, and did not make, a recommendation as to whether any holder of General Re Common Stock who is entitled to make a Class A Election should make such a Class A Election. Goldman Sachs noted that it was expected that the General Re Merger will be tax-free to the holders of General Re Common Stock but that, in the event that the Alternative Transaction occurs, holders of General Re Common Stock will recognize gain or loss for federal income tax purposes. Goldman Sachs noted that in rendering its opinion Goldman Sachs did not take into account the particular tax consequences of the General Re Merger or the Alternative Transaction to the holders of General Re Common Stock. The Goldman Sachs Opinion was necessarily based upon financial, economic, market and other conditions as they existed and could be evaluated on the date of such opinion.

The following is a summary of certain of the financial analyses reviewed by Goldman Sachs with the General Re Board on June 19, 1998 and used by Goldman Sachs in connection with providing its oral opinion to the General Re Board on June 19, 1998 and in providing the written Goldman Sachs Opinion.

Summary of Terms of Proposed Transaction. Goldman Sachs reviewed the terms of the proposed Transactions, including the exchange ratios for the shares of General Re Common Stock in the Transactions, the consideration per share of General Re Common Stock and the aggregate consideration. Utilizing a price of $78,500 (the closing price on the New York Stock Exchange of the Berkshire Class A Common Stock on June 17, 1998) (the "Berkshire June 17 Closing Price") and applying an exchange ratio equal to 0.0035 shares of New Berkshire Class A Common Stock for each share of General Re Common Stock, Goldman Sachs calculated a consideration per share of General Re Common Stock equal to $274.75 (the "Per Share Consideration") and an aggregate consideration equal to approximately $21.7 billion (the "Aggregate Consideration").

Transaction Multiples. Utilizing a Per Share Consideration equal to $274.75, Goldman Sachs analyzed the consideration to be paid per share of General Re Common Stock in relation to (i) $225.63 (the closing price on

26

the New York Stock Exchange of General Re Common Stock on June 17, 1998) (the "General Re June 17 Closing Price"), (ii) $228.06 (the latest twelve months' ("LTM") high closing price on the New York Stock Exchange of General Re Common Stock (the "LTM High")), (iii) $182.00 (the LTM low closing price on the New York Stock Exchange of General Re Common Stock (the "LTM Low")), (iv) the 1997 actual earnings per share ("EPS") of General Re Common Stock, (v) the LTM EPS of General Re Common Stock (the "LTM EPS"), (vi) the estimated 1998 EPS for General Re Common Stock based on median 1998 earnings estimates for General Re reported by the Institutional Brokers Estimates System ("IBES") (the "1998 IBES EPS Estimate"), (vii) the estimated 1999 EPS for General Re Common Stock based on median 1999 earnings estimates for General Re reported by IBES (the "1999 IBES EPS Estimate"), (viii) General Re's stated shareholders' equity (including and excluding the effect of Statement of Financial Accounting Standards No. 115 ("FAS 115")), and (ix) General Re's tangible shareholders' equity (including and excluding the effect of FAS 115). All EPS calculations exclude realized gains on investments taxed at 35%, and all shareholders' equity calculations are as of March 31, 1998, include the proceeds from the exercise of outstanding stock options and are on a fully-diluted basis.

Such analysis indicated that the Per Share Consideration represented: (i) a 21.8% premium to the General Re June 17 Closing Price, (ii) a 20.5% premium to the LTM High, (iii) a 51.0% premium to the LTM Low, (iv) 23.4x the actual 1997 EPS of General Re Common Stock, (v) 23.1x the LTM EPS, (vi) 21.3x the 1998 IBES EPS Estimate, (vii) 19.5x the 1999 IBES EPS Estimate, (viii) 2.7x General Re's stated shareholders' equity (including the effect of FAS 115), (ix) 3.0x General Re's tangible shareholders' equity (including the effect of FAS 115),
(x) 3.9x General Re's stated shareholders' equity (excluding the effect of FAS 115), and (xi) 4.7x General Re's tangible shareholders' equity (excluding the effect of FAS 115).

Comparable Public Company Analysis. Goldman Sachs reviewed and compared certain financial information relating to General Re to corresponding financial information, ratios and public market multiples for two groups of selected publicly traded companies in the insurance industry considered by Goldman Sachs to be reasonably comparable to General Re for purposes of this analysis. Such comparable companies consisted of: (i) Transatlantic Holdings, Inc., Everest Reinsurance Holdings, NAC Re Corporation, Trenwick Group Inc. and Chartwell Re Corporation (the "U.S. Reinsurance Companies"), and (ii) American International Group Inc., Allstate Corporation, Travelers Property Casualty Corporation, Hartford Financial Services Group Inc., The St. Paul Companies, Inc., Progressive Corporation and SAFECO Corporation (the "Property and Casualty Companies", and together with the U.S. Reinsurance Companies, the "Comparable Companies"). Goldman Sachs calculated and compared various financial multiples and ratios for General Re with those of the Comparable Companies using the respective closing price per common share on June 17, 1998. The multiples and ratios for General Re and the Comparable Companies were based on the most recent publicly available information and on median IBES estimates.

With respect to the Comparable Companies and General Re, Goldman Sachs considered, among other multiples and ratios, (i) the June 17, 1998 closing price as a percentage of the 52 week high, (ii) the price/earnings ("P/E") multiple based on 1998 and 1999 IBES estimates, (iii) the IBES estimate of five-year EPS growth rate, (iv) the market price to adjusted book value (excluding the effect of FAS 115) multiple, (v) the return on average common equity ("ROE") based on IBES 1998 estimates (calculated as IBES 1998 estimates of operating earnings divided by common equity excluding FAS 115 adjustments),
(vi) the dividend yield, (vii) the debt to capital ratio, and (viii) the net premiums written to statutory surplus ratio (based on LTM net premiums written).

Goldman Sachs' analysis indicated that (i) the June 17, 1998 closing price as a percentage of the 52 week high ranged from 80% to 96% with a median of 87% for the U.S. Reinsurance Companies, and from 80% to 98% with a median of 91% for the Property and Casualty Companies, as compared to 99% for General Re, (ii) 1998 P/E multiples ranged from 9.7x to 14.5x with a median of 12.0x for the U.S. Reinsurance Companies, and from 13.0x to 26.7x with a median of 15.1x for the Property and Casualty Companies, as compared to 17.5x for General Re, (iii) 1999 P/E multiples ranged from 8.9x to 13.4x with a median of 10.7x for the U.S. Reinsurance Companies, and from 11.9x to 23.3x with a median of 13.6x for the Property and Casualty

27

Companies, as compared to 16.0x for General Re, (iv) five year estimated growth rates ranged from 10.0% to 13.0% with a median of 11.3% for the U.S. Reinsurance Companies, and from 10.0% to 15.0% with a median of 12.0% for the Property and Casualty Companies, as compared to 12.0% for General Re, (v) the market price to adjusted book value multiple ranged from 1.1x to 2.0x with a median of 1.5x for the U.S. Reinsurance Companies, and from 1.5x to 5.1x with a median of 2.8x for the Property and Casualty Companies, as compared to 3.1x for General Re, (vi) ROE ranged from 10.8% to 14.1% with a median of 11.4% for the U.S. Reinsurance Companies, and from 10.1% to 19.2% with a median of 17.1% for the Property and Casualty Companies, as compared to 17.7% for General Re,
(vii) dividend yield ranged from 0.5% to 2.7% with a median of 0.6% for the U.S. Reinsurance Companies, and from 0.2% to 3.1% with a median of 1.2% for the Property and Casualty Companies, as compared to 1.0% for General Re,
(viii) the debt to capital ratio ranged from 0.0% to 32.4% with a median of 24.6% for the U.S. Reinsurance Companies, and from 10.1% to 41.4% with a median of 21.3% for the Property and Casualty Companies, as compared to 4.7% for General Re, and (ix) the net premiums written to statutory surplus ratio ranged from 0.6x to 1.1x with a median of 1.0x for the U.S. Reinsurance Companies, and from 0.6x to 2.9x with a median of 0.9x for the Property and Casualty Companies, as compared to 0.5x for General Re's U. S. operations.

Comparison of Total Annual Returns. Goldman Sachs reviewed and compared the Total Annual Return (defined as the annualized appreciation of common stock price plus dividends received) with respect to each of General Re, Berkshire, American International Group Inc., Progressive Corporation and the S&P 500 Index over (to the extent applicable) the one, three, five, ten, fifteen and twenty year periods ending June 17, 1998. Goldman Sachs' analysis indicated that (i) the Total Annual Return on the General Re Common Stock was 22.54%, 21.15%, 17.13%, 17.32% and 16.12% over the one, three, five, ten and fifteen year periods, respectively, ending June 17, 1998, (ii) the Total Annual Return on the Berkshire Class A Common Stock was 69.18%, 52.11%, 37.50%, 34.85%, 44.62% and 35.51% over the one, three, five, ten, fifteen and twenty year periods, respectively, ending June 17, 1998, (iii) the Total Annual Return on the common stock of American International Group Inc. was 38.97%, 38.62%, 28.93%, 25.94% and 20.79% over the one, three, five, ten and fifteen year periods, respectively, ending June 17, 1998, (iv) the Total Annual Return on the common stock of Progressive Corporation was 70.28%, 56.25%, 37.43% and 31.08% over the one, three, five and ten year periods, respectively, ending June 17, 1998, and (v) the Total Annual Return of the S&P 500 Index was 23.78%, 27.04%, 19.81%, 15.13%, 13.34% and 12.92% over the one, three, five, ten, fifteen and twenty year periods, respectively, ending June 17, 1998.

Berkshire Historical Outperformance. Goldman Sachs reviewed and compared the average amount, if any, by which the percentage increase in the book value and price per share of the Berkshire Class A Common Stock exceeded the percentage increase in the S&P 500 Index over the three month period ending March 31, 1998 and over the one, three, five, ten, fifteen and twenty year periods ending December 31, 1997. Goldman Sachs' analysis indicated that (i) the percentage increase in the S&P 500 Index exceeded the percentage increase in the book value per share of the Berkshire Class A Common Stock by 3.6% over the three month period ending March 31, 1998, (ii) the percentage increase in the price per share of the Berkshire Class A Common Stock exceeded the percentage increase in the S&P 500 Index by 32.6% over the three month period ending March 31, 1998, (iii) the annual percentage increase in the book value per share of the Berkshire Class A Common Stock exceeded the annual percentage increase in the S&P 500 Index by 0.7%, 5.1%, 6.6%, 8.2%, 9.2% and 10.9% over the one, three, five, ten, fifteen and twenty year periods, respectively, ending December 31, 1997, (iv) the annual percentage increase in the price per share of the Berkshire Class A Common Stock exceeded the annual percentage increase in the S&P 500 Index by 1.5%, 11.1%, 13.5%, 13.8% and 17.1% over the one, five, ten, fifteen and twenty year periods, respectively, ending December 31, 1997, and (v) the annual percentage increase in the S&P 500 Index exceeded the annual percentage increase in the price per share of the Berkshire Class A Common Stock by 0.1% over the three year period ending December 31, 1997.

Present Value of Consideration Received Analysis. Goldman Sachs noted that it is the opinion of certain commentators that Berkshire's stock has from time to time traded above the intrinsic value per share of Berkshire, reflecting a "Berkshire Premium", and that the amount of any Berkshire Premium has varied over

time. In its analyses, Goldman Sachs did not estimate the intrinsic value per share of General Re or Berkshire, or the amount or expected future duration, if any, of any Berkshire Premium.

To help assess the potential effect of a Berkshire Premium, Goldman Sachs performed an analysis of the implied present value of the consideration to be received in the Transactions per share of General Re Common Stock over periods of three, five, seven and ten years as derived on the basis of the Aggregate Pro Forma Value (as defined below) of the Transactions, utilizing a discount rate of 10%, a current aggregate intrinsic value of the General Re Common Stock equal to the Aggregate Consideration (the "Aggregate General Re Value") and a range of assumed intrinsic values per share of Berkshire Class A Common Stock (each such intrinsic value per share being a "Berkshire Intrinsic Value Per Share"). Goldman Sachs derived a range of Berkshire Intrinsic Values Per Share calculated by reference to the Berkshire June 17 Closing Price, assuming that such price included a Berkshire Premium equal to 0%, 5%, 15%, 25%, 35% and 45% of the Berkshire Intrinsic Value Per Share. In order to calculate the "Aggregate Pro Forma Value" of the Transactions, Goldman Sachs multiplied each Berkshire Intrinsic Value Per Share by the number of issued and outstanding shares of Berkshire Common Stock (as adjusted to take into account the economic relationship between the Berkshire Class A Common Stock and the Berkshire Class B Common Stock), and added to each resulting amount the Aggregate General Re Value. Goldman Sachs applied three assumed growth rates to the range of Aggregate Pro Forma Values obtained. Such growth rates were characterized by Goldman Sachs as percentage amounts (7%, 5% and 3%) (each such percentage amount being a "Berkshire Outperformance Percentage") by which the growth rate of a range of Aggregate Pro Forma Values exceeds an assumed S&P Index annual growth rate of 10%.

Goldman Sachs analysis indicated that (i) over a ten year period, the implied present value of the consideration to be received per share of General Re Common Stock was greater than the Per Share Consideration in each scenario other than when the Berkshire Outperformance Percentage was equal to 3% and the Berkshire Premium was equal to 45%, (ii) over a seven year period, the implied present value of the consideration to be received per share of General Re Common Stock was greater than the Per Share Consideration in each scenario other than when the Berkshire Outperformance Percentage was equal to 3% and the Berkshire Premium was equal to 35% and 45%, (iii) over a five year period, the implied present value of the consideration to be received per share of General Re Common Stock was greater than the Per Share Consideration in each scenario other than (x) when the Berkshire Outperformance Percentage was equal to 3% and the Berkshire Premium was equal to 25%, 35% and 45% and (y) when the Berkshire Outperformance Percentage was equal to 5% and the Berkshire Premium was equal to 35% and 45%, and (iv) over a three year period, the implied present value of the consideration to be received per share of General Re Common Stock was greater than the Per Share Consideration in each scenario other than (x) when the Berkshire Outperformance Percentage was equal to 3% and the Berkshire Premium was equal to 15%, 25%, 35% and 45%, (y) when the Berkshire Outperformance Percentage was equal to 5% and the Berkshire Premium was equal to 25%, 35% and 45%, and (z) when the Berkshire Outperformance Percentage was equal to 7% and the Berkshire Premium was equal to 35% and 45%. Goldman Sachs noted that if the Berkshire Common Stock traded with a Berkshire Premium in the future, the number of instances where the Per Share Consideration was less than the implied present value of the consideration to be received per share of General Re Common Stock would be reduced and in some cases eliminated.

Pro Forma Merger Analysis. Goldman Sachs analyzed the estimated pro forma effect of the Transactions on the EPS of General Re and Berkshire on both a reported income and a comprehensive income basis. Goldman Sachs noted that comprehensive income is equal to net income plus after-tax unrealized appreciation in investment portfolio and foreign translation adjustments. Goldman Sachs' analysis was based on, among other things, the following assumptions: (i) approximately $14.5 billion of goodwill amortized over 40 years, and (ii) an effective capital gains tax rate of 35%. In addition, in its analysis, Goldman Sachs excluded the effects of any cost savings and synergies. In connection with its analysis of estimated pro forma EPS on a reported income basis, Goldman Sachs utilized (i) with respect to General Re, the 1998 IBES EPS Estimate and the 1999 IBES EPS Estimate, and (ii) with respect to Berkshire, EPS estimates for Berkshire as calculated by Goldman Sachs based on historical net operating income of Berkshire (excluding all realized investment gains), as adjusted for certain intervening acquisitions by Berkshire, and an assumed annual growth rate of 12.5%. In connection with

29

its analysis of estimated pro forma EPS on a comprehensive income basis, Goldman Sachs utilized (i) with respect to General Re, the 1998 IBES EPS Estimate and the 1999 IBES EPS Estimate and an assumed rate of appreciation of General Re's equity portfolio equal to 10% per annum, and (ii) with respect to Berkshire, EPS estimates for Berkshire as calculated by Goldman Sachs based on historical net operating income of Berkshire, an assumed annual growth rate of 12.5% per annum and an assumed rate of appreciation of Berkshire's equity portfolio equal to 15% per annum.

Goldman Sachs' analysis indicated that (i) on a reported EPS basis, the proposed Transactions would be highly dilutive to holders of General Re Common Stock and substantially accretive to holders of Berkshire Common Stock in 1998 and 1999, and (ii) on a comprehensive EPS basis, the proposed Transactions would be substantially dilutive to holders of General Re Common Stock and mildly dilutive (1.2% and 1.3%, respectively) to holders of Berkshire Common Stock in 1998 and 1999. Goldman Sachs noted that, in view of the trading characteristics of the Berkshire Common Stock (particularly the high P/E multiples at which the Berkshire Common Stock trades), an earnings-based analysis does not provide a meaningful measure or indication of the estimated pro forma effect of the Transactions. Goldman Sachs noted, however, that the analysis of the comprehensive EPS effect of the Transactions on the holders of Berkshire Common Stock was the most relevant earnings-based means by which to measure the estimated pro forma effect of the Transactions.

Pro Forma Contribution and Ownership Analysis. Goldman Sachs analyzed and compared the respective contribution of net income (including realized gains on investments), operating income (excluding realized gains on investments based upon an assumed 35% tax rate), comprehensive income (net income plus after-tax unrealized appreciation in investment portfolio and foreign translation adjustments) and book value of General Re and Berkshire to the combined entity resulting from the Transactions. Based upon figures for the twelve months ended March 31, 1998 or as of March 31, 1998, as the case may be, Goldman Sachs noted that the contribution of General Re to the net income, operating income, comprehensive income and book value of the combined entity resulting from the Transactions would be 29.9%, 45.2%, 16.8% and 19.4%, respectively.

Goldman Sachs performed an analysis of the pro forma equity ownership of the combined entity resulting from the Transactions of the holders of General Re Common Stock. Goldmans Sachs' analysis indicated that holders of General Re Common Stock would own approximately 18.2% of the equity of the combined entity resulting from the Transactions.

The summary set forth above does not purport to be a complete description of the analyses performed by Goldman Sachs. The preparation of a fairness opinion is a complex process and is not susceptible to partial analysis or summary description. Selecting portions of the analyses or the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying the Goldman Sachs Opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all such analyses and did not assign relative weights to any of the analyses. No public company used in the above analyses as a comparison is completely comparable to General Re or Berkshire. The analyses were prepared solely for purposes of Goldman Sachs providing the Goldman Sachs Opinion to the General Re Board and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold or may trade in the future. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of General Re, Berkshire, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast. As described above, the Goldman Sachs Opinion delivered to the General Re Board was one of many factors taken into consideration by the General Re Board in making its determination to approve the Merger Agreement.

Goldman Sachs, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. Goldman Sachs is familiar with General Re, having acted as its financial advisor in connection with, and having participated in certain of the negotiations leading to, the Merger

30

Agreement. Goldman Sachs is familiar with Berkshire, having acted in 1996 as co-manager of Berkshire's public offering of $500 million principal amount of 1.00% Senior Exchangeable Notes due December 2, 2001. In addition, on July 22, 1998, Berkshire agreed to acquire Executive Jet, Inc. An investment fund affiliated with Goldman Sachs (and in which Goldman Sachs has a financial interest) is an approximately 27% stockholder of Executive Jet, Inc. In connection with the transaction, Goldman Sachs also acted as the financial advisor to, and will receive an advisory fee from, Executive Jet, Inc.

Goldman Sachs provides a full range of financial, advisory and brokerage services and in the course of its normal trading activities may from time to time effect transactions and hold positions in the securities or options on securities of General Re and/or Berkshire for its own account and/or for the account of customers.

Pursuant to a letter agreement (the "Goldman Sachs Engagement Letter"), General Re engaged Goldman Sachs as its financial advisor in connection with the possible sale of all or a portion of General Re to Berkshire. Pursuant to the terms of the Goldman Sachs Engagement Letter, General Re has agreed to pay to Goldman Sachs a transaction fee of 0.145% of the aggregate consideration paid in a transaction in which the purchase of 50% or more of the outstanding shares of General Re Common Stock is accomplished. Any such transaction fee is payable to Goldman Sachs in cash in accordance with the following schedule:
(i) $3 million upon execution of the agreement with respect to such transaction, and (ii) the remainder upon consummation of any such transaction. General Re also has agreed to reimburse Goldman Sachs for its reasonable out- of-pocket expenses, including all fees and disbursements of counsel, and to indemnify Goldman Sachs and certain related persons against certain liabilities in connection with their engagement, including certain liabilities under the federal securities laws.

PROCEDURES FOR ELECTION OF MERGER CONSIDERATION AND SURRENDER OF GENERAL RE COMMON STOCK CERTIFICATES; FRACTIONAL SHARES

General Re. Each holder of an outstanding certificate which, immediately prior to the Effective Time, represented shares of General Re Common Stock may elect the aggregate number of shares of General Re Common Stock represented by the certificate(s) surrendered therewith to be converted into the right to receive shares of New Berkshire Class A Common Stock (or, if the Alternative Transaction occurs, Berkshire Class A Common Stock and cash) (a "Class A Election") . All shares of General Re Common Stock represented by such certificate for which a Class A Election has not been effectively made shall be converted into the right to receive New Berkshire Class B Common Stock (or, if the Alternative Transaction occurs, Berkshire Class B Common Stock and cash).

Shares of New Berkshire Class A Common Stock and New Berkshire Class B Common Stock will have different voting rights and shares of New Berkshire Class B Common Stock will not be convertible into shares of New Berkshire Class A Common Stock, exactly as is the case with the existing Berkshire Class A and Class B Common Stock. In addition, stockholders of record of New Berkshire Class A Common Stock may designate charitable contributions to be made by the corporation. In 1997, stockholders of record of Berkshire Class A Common Stock as of August 31, 1997 were entitled to designate $16 per share, an amount that is expected to increase in the future. It is anticipated that this program will continue in the future for stockholders of record of Class A Common Stock. Shares of Class B Common Stock do not participate in this program. Accordingly, General Re stockholders who receive shares of New Berkshire or Berkshire Class B Common Stock will not be entitled to participate in this program with respect to such shares. See "Certain Risk Factors and Investment Considerations" and "Description of New Berkshire Capital Stock."

No certificates or scrip representing fractional shares of New Berkshire or Berkshire Common Stock will be issued upon the surrender for exchange of certificates representing shares of General Re Common Stock, and such fractional share interests will not entitle the owner thereof to vote or to any rights as a stockholder. Each holder of shares of General Re Common Stock exchanged pursuant to the General Re Merger who would have otherwise been entitled to receive a fraction of a share of Class A Common Stock will receive, in lieu thereof, the number of whole shares of Class B Common Stock determined by multiplying such fraction by 30. After

31

application of the procedure described in the previous sentence, each holder of shares of General Re Common Stock exchanged pursuant to the General Re Merger who would have otherwise been entitled to receive a fraction of a share of Class B Common Stock will receive, in lieu thereof, a cash payment (without interest) equal to the product of (x) such fraction and (y) the Average Trading Price of Berkshire Class B Common Stock.

The Exchange Agent is BankBoston, N.A., whose address is c/o Boston Equiserve 150 Royall Street, Canton, Massachusetts 02021.

In order to receive the Merger Consideration, a General Re stockholder must surrender to the Exchange Agent the certificate or certificates which, prior to the Effective Time, represented outstanding shares of General Re Common Stock. As soon as practicable after the Effective Time, the Exchange Agent will send to each such stockholder a letter of transmittal and instructions for use in effecting the Class A Election, if desired, and the surrender of certificates. The Exchange Agent will accept such certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices.

After the Effective Time of the Merger, there will be no further transfer on the records of General Re or its transfer agent of certificates representing shares of General Re Common Stock and if such certificates are presented to General Re for transfer, they will be cancelled against delivery of the Merger Consideration pursuant to the Merger Agreement. Until surrendered in accordance with the Merger Agreement, each certificate for shares of General Re Common Stock will be deemed at any time after the Effective Time of the Mergers to represent only the right to receive upon such surrender the Merger Consideration pursuant to the Merger Agreement. No interest will be paid or will accrue on any cash payable as consideration in the Mergers or in lieu of any fractional shares of New Berkshire or Berkshire Common Stock.

No dividends or other distribution with respect to New Berkshire or Berkshire Common Stock with a record date after the Effective Time of the Mergers will be paid to the holder of any unsurrendered certificate for shares of General Re Common Stock with respect to the shares of New Berkshire or Berkshire Common Stock represented thereby and no payment of cash as Merger Consideration, in lieu of fractional shares or for dividends or distributions on New Berkshire or Berkshire Common Stock will be paid to any such holder until the surrender of such certificate in accordance with the Merger Agreement. Subject to the effect of applicable laws, following surrender of any such certificate, there will be paid to the holder of the certificate representing whole shares of New Berkshire or Berkshire Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender the amount of any cash payable in lieu of a fractional share of Class B Common Stock to which such holder is entitled pursuant to the Merger Agreement and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to whole shares of such stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to whole shares of such stock.

Berkshire. In no event will holders of shares of Berkshire Common Stock be required to exchange their stock certificates. At the Effective Time, each certificate representing shares of Berkshire Class A or Class B Common Stock will, without any action on the part of the holder thereof, be deemed to represent a certificate for an equal number of shares of New Berkshire Class A or Class B Common Stock, respectively. In the event of the Alternative Transaction, there will be no change, deemed or otherwise, with respect to Berkshire Common Stock. HOLDERS OF BERKSHIRE COMMON STOCK SHOULD NOT SEND ANY CERTIFICATES REPRESENTING BERKSHIRE COMMON STOCK WITH THE ENCLOSED PROXY CARD OR TO THE EXCHANGE AGENT.

STOCK OPTION AGREEMENT

In connection with the Merger Agreement, Berkshire and General Re entered into the Stock Option Agreement. The following description of the Stock Option Agreement does not purport to be complete and is qualified in its entirety by reference to the Stock Option Agreement, a copy of which is attached as Annex II to this Joint Proxy Statement/Prospectus. Pursuant to the Stock Option Agreement, General Re granted Berkshire

32

an irrevocable option (the "Option") to purchase up to 15,000,000 shares of General Re Common Stock at a cash purchase price equal to $283.71 per share (the "Option Purchase Price"). The Option may be exercised by Berkshire, in whole or in part, at any time, or from time to time, following (but not prior to) the occurrence of one of the Triggering Events (as defined below) and prior to the termination of the Option in accordance with the terms of the Stock Option Agreement.

The Stock Option Agreement provides that in the event of any change in the number of issued and outstanding shares of General Re Common Stock by reason of any stock dividend, stock split, split-up, recapitalization, reorganization or other change in the corporate or capital structure of General Re, the number and/or kind of General Re shares subject to the Option and the purchase price per General Re share will be appropriately adjusted to restore Berkshire to its rights, including its right to purchase shares of General Re Common Stock representing 19.9% of the capital stock of General Re entitled to vote generally for the election of the directors which is issued and outstanding immediately prior to the exercise of the Option.

A "Triggering Event" occurs when (a) any person (other than Berkshire or any of its subsidiaries) has acquired beneficial ownership (as such term is defined in Rule 13d-3 under the Securities Exchange Act of 1934 (the "Exchange Act")) or the right to acquire beneficial ownership of, or any "group" (as such term is defined under the Exchange Act) has been formed which beneficially owns or has the right to acquire beneficial ownership of, General Re Common Stock aggregating 20 percent or more of the then outstanding General Re Common Stock; (b) General Re shall have terminated the Merger Agreement to enter into an agreement for a Superior Proposal (as defined under "Certain Provisions of the Merger Agreement--No Solicitation"); (c) a Takeover Proposal (as defined under "Certain Provisions of the Merger Agreement--No Solicitation") shall have been made to General Re or any of its subsidiaries or any of its stockholders or any person shall have publicly announced an intention (whether or not conditional) to make a Takeover Proposal with respect to General Re or any of its subsidiaries, and thereafter the Merger Agreement shall have been terminated by either Berkshire or General Re because of the failure to obtain the required approval of the stockholders of General Re, and within 18 months of the date of such termination General Re entered into any Third Party Acquisition Agreement (as defined under "Certain Provisions of the Merger Agreement--No Solicitation"), or the Merger Agreement shall have been terminated by Berkshire because (A) General Re withdrew, modified or amended in any respect adverse to Berkshire or New Berkshire its approval or recommendation of the Merger Agreement or the General Re Transactions, recommended any Takeover Proposal from a person other than Berkshire or resolved to do any of the foregoing, or (B) General Re, in response to a Superior Proposal, furnished information or participated in discussion as permitted by the Merger Agreement, and such discussions, directly or through agents or representatives, continued for more than 10 business days after the receipt of such Superior Proposal, or a Takeover Proposal was publicly disclosed commenced or was publicly proposed or communicated to General Re and which contained a proposal as to price (without regard to whether such proposal specified a specific price or a range of potential prices) and General Re did not reject such proposal within 10 business days of its receipt or, if sooner, the date its existence first became publicly disclosed, and, in any event described in this clause (B), within 18 months of the date of such termination General Re entered into any Third Party Acquisition Agreement.

Pursuant to the Stock Option Agreement, at any time the Option is exercisable, Berkshire may elect, by sending a written notice to General Re (the "Cash Exercise Notice"), in lieu of exercising the Option for shares of General Re Common Stock, to have General Re pay cash in an amount equal to the Spread (as defined below) multiplied by all or such portion of the General Re shares subject to the Option as Berkshire specifies. The term "Spread" is defined in the Stock Option Agreement as the excess, if any, over the Option Purchase Price of the higher of (i) if applicable, the highest price per share of General Re Common Stock paid or proposed to be paid in cash or property by any person pursuant to any Takeover Proposal or (ii) the closing price of the shares of General Re Common Stock on the NYSE Composite Tape on the last trading day immediately prior to the date of the Cash Exercise Notice (the "Closing Price").

Pursuant to the terms of the Stock Option Agreement, General Re's obligations to deliver General Re shares upon exercise of the Option is subject only to the conditions that: (a) no preliminary or permanent injunction or

33

other order issued by any federal or state court of competent jurisdiction in the United States prohibiting the delivery of the General Re shares is in effect; (b) any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act") shall have expired or shall have been terminated; (c) any other consent, approval, order, notification, or authorization, the failure of which to obtain or make would make the issuance of the General Re shares illegal, shall have been obtained or made and be in full force and effect; and (d) a Triggering Event shall have occurred.

The Stock Option Agreement provides that, if within 18 months after the date the Merger Agreement was terminated pursuant to the terms thereof (the "Merger Termination Date"), neither Berkshire nor any other person has acquired more than fifty percent (excluding the General Re shares purchased pursuant to the Option) of the outstanding General Re Common Stock, then General Re has the right to purchase (the "Repurchase Right") all, but not less than all, of the General Re shares acquired upon exercise of the Option of which Berkshire is the beneficial owner on the date General Re gives written notice of its intention to exercise the Repurchase Right at the greater of (a) the Option Purchase Price or (b) the average of the last sales prices for shares of General Re Common Stock on the thirty trading days ending on the date General Re gives written notice of its intention to exercise the Repurchase Right. If General Re does not exercise the Repurchase Right within thirty days following the date the Repurchase Right becomes exercisable, the Repurchase Right expires and cannot be exercised.

The Stock Option Agreement also provides that at any time prior to the date that is 18 months after the Merger Termination Date, Berkshire will have the right to sell (the "Sale Right") to General Re all, but not less than all, of the General Re shares acquired upon exercise of the Option of which Berkshire is the beneficial owner on the date Berkshire gives written notice of its intention to exercise the Sale Right at the greater of (a) the Option Purchase Price, or (b) the average of the last sales prices for shares of General Re Common Stock on the 30 trading days ending on the date Berkshire gives written notice of its intention to exercise the Sale Right. If Berkshire does not exercise the Sale Right within thirty days following the date the Sale Right becomes exercisable, the Sale Right expires and cannot be exercised.

The Stock Option Agreement provides that the right to exercise the Option will terminate at the earliest of (a) the Effective Time, (b) the date 120 days after the Option first becomes exercisable (if the Option is not previously exercised) and (c) if not then exercisable, thirty days after termination of the Merger Agreement in accordance with its terms (the "Option Termination Date") provided, if the Option cannot be exercised or the General Re shares cannot be delivered because (a) an injunction or other order issued by a federal or state court of competent jurisdiction in the U.S. prohibits the delivery of the General Re shares, (b) the waiting period under the HSR Act has not expired or been terminated or (c) any consent, approval, order, notification, or authorization, the failure of which to obtain or make would make the issuance of the General Re shares illegal, has not been obtained or made and is in full force and effect, the Option Termination Date will be extended until 30 days after such impediment to exercise or delivery has been removed.

The Stock Option Agreement provides that in no event will Berkshire's Total Profit (as defined below) exceed $600 million and, if it otherwise would exceed such amount, Berkshire will repay such excess amount to General Re in cash (or the purchase price of the Repurchase Right or the Sale Right, as applicable, will be reduced) so that Berkshire's Total Profit will not exceed $600 million after taking into account the foregoing actions.

The Stock Option Agreement further provides that the Option may not be exercised for a number of General Re Shares as would, as of the date of the Stock Exercise Notice (as defined in the Stock Option Agreement), result in a Notional Total Profit (as defined below) of more than $600 million and, if exercise of the Option otherwise would exceed such amount, Berkshire, at its discretion, may increase the Option Purchase Price for that number of shares of General Re Common Stock set forth in the Stock Exercise Notice so that the Notional Total Profit will not exceed $600 million. The Stock Option Agreement provides that this restriction will not restrict any exercise of the Option permitted on any subsequent date at the Option Purchase Price.

34

The term "Total Profit" is defined in the Stock Option Agreement as the aggregate amount (before taxes) of the following: (a) (i) the amount of cash received by Berkshire as the Termination Fee (see "Certain Provisions of The Merger Agreement--Termination Fee") and the amount received by Berkshire as cash in lieu of General Re shares upon exercise of the Option for cash (as described above), less (ii) any repayment of such cash to General Re, (b) (i) the amount received by Berkshire pursuant to General Re's repurchase of General Re shares, less (ii) Berkshire's purchase price for such General Re shares, and (c) (i) the net cash amounts received by Berkshire pursuant to the sale of General Re shares (or any other securities into or for which such General Re Shares are converted or exchanged) to any unaffiliated party, less
(ii) Berkshire's purchase price for such General Re shares.

As used in the Stock Option Agreement the term "Notional Total Profit," with respect to any number of General Re shares as to which Berkshire may propose to exercise the Option, will be the Total Profit determined as of the date of the Stock Exercise Notice assuming that the Option was exercised on such date for such number of General Re shares and assuming that such General Re shares together with all other General Re shares acquired upon exercise of the Option and held by Berkshire and its affiliates as of such date, were sold for cash at the closing market price for the General Re Common Stock as of the close of business on the preceding trading day.

OTHER AGREEMENTS AND TRANSACTIONS

Voting Agreements. In connection with the Merger Agreement, Warren E. Buffett and Charles T. Munger, the beneficial owners of approximately 40% and 1.5%, respectively, of the voting power of Berkshire Common Stock entered into voting agreements with General Re (the "Voting Agreements.") The following description of the Voting Agreements does not purport to be complete and is qualified in its entirety by reference to the form of Voting Agreement which is attached as Annex III hereto. Pursuant to the Voting Agreements, Mr. Buffett and Mr. Munger have each agreed to vote the shares of Class A Common Stock beneficially owned by them, other than any such shares that they give as gifts to family members or charities (the "Voting Agreement Shares"), in favor of the adoption of the Merger Agreement and approval of the Berkshire Merger and the Transactions and in favor of any other matter necessary to the consummation of the Transactions considered and voted upon at the Berkshire Meeting. The Voting Agreements also provide, among other things, that until the close of business on the date of the Berkshire Meeting, Mr. Buffett and Mr. Munger will not (a) sell, pledge, or otherwise dispose of any of the Voting Agreement Shares, (b) deposit the Voting Agreement Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Voting Agreement Shares, or grant any proxy with respect thereto (other than a proxy naming such person as one of the proxy holders), (c) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer or other disposition of any of the Voting Agreement Shares, or (d) convert any of the Voting Agreement Shares into shares of Berkshire Class B Common Stock.

Redemption of General Re Preferred Stock. Pursuant to the Merger Agreement, and as a condition to Berkshire's obligation to consummate the Transactions, General Re has agreed to take all actions necessary to call for redemption, and to redeem, all of the shares of General Re Preferred Stock as of immediately prior to the Effective Time. Shares of General Re Preferred Stock may be converted into shares of General Re Common Stock until the close of business on the date of redemption.

Preferred Stock Issuance. Pursuant to the Merger Agreement, as of June 29, 1998 Berkshire issued to General Re 10,000 shares of its 5.10% Preferred Stock, without par value ("Berkshire 5.10% Preferred Stock"), a non-voting, non-participating cumulative preferred stock, with an aggregate face amount of $1,000,000, redeemable at face amount (plus accrued but unpaid dividends) at Berkshire's option after five years from the date of issuance, and in exchange General issued to Berkshire 10,000 shares of its 5.10% Preferred Stock, without par value ("General Re 5.10% Preferred Stock") having equivalent value and substantially identical terms. The Berkshire 5.10% Preferred Stock and the General Re 5.10% Preferred Stock will not be converted in the Mergers and will remain outstanding following the Effective Time.

35

EFFECTIVE TIME

On the Closing Date, the parties will file certificates of merger or other appropriate documents (in any such case, the "Certificates of Merger") and will make all other filings or recordings required under the Delaware General Corporation Law ("DGCL"). The Mergers will become effective at such time as the Certificate of Mergers are duly filed with the Secretary of State of the State of Delaware, or at such other time as Berkshire and General Re specify in the Certificates of Merger (the time the Mergers become effective being the "Effective Time"). Such filing will be made as promptly as practicable after satisfaction or waiver of the conditions to the Mergers.

EFFECT ON GENERAL RE STOCK PLANS

The Merger Agreement provides that as a result of the Transactions each outstanding and unexercised stock option to purchase shares of General Re Common Stock and stock appreciation rights (payable in shares of General Re Common Stock) granted under the General Re stock plans (the "General Re Stock Plans") will cease to represent the right to acquire shares of General Re Common Stock and will be converted into and become a right with respect to New Berkshire Common Stock. Pursuant to the terms of the General Re Stock Plans, as a result of the Transactions the unvested stock options and stock appreciation rights which were granted prior to June 9, 1998 and held by employees will become fully vested and exercisable. In addition, upon certain terminations of employment within two years following the General Re Merger, the restrictions on the shares of restricted stock and restricted share units will lapse.

EFFECT ON BERKSHIRE STOCK PLAN

Each outstanding option or right to purchase shares of Berkshire Class B Common Stock (a "Berkshire Option") will, if agreed by the holder of such Berkshire Option (if such agreement is required), be assumed by New Berkshire in such manner that it is converted into an option to purchase shares of New Berkshire Class B Common Stock, with each such Berkshire Option to otherwise be exercisable upon the same terms and conditions as then are applicable to such Berkshire Option, including the number of shares and exercise price provided thereby. New Berkshire will assume all rights and obligations of Berkshire under Berkshire's stock option plan as in effect at the Effective Time and shall continue such plans in accordance with their terms. In the event of the Alternative Transaction, there will be no change to the Berkshire Options.

FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material United States federal income tax consequences of the Mergers and the Alternative Transaction to holders of Berkshire Common Stock and General Re Voting Stock who hold such stock as a capital asset. The summary is based on the Code, Treasury regulations thereunder, and administrative rulings and court decisions in effect as of the date hereof, all of which are subject to change at any time, possibly with retroactive effect. This summary is not a complete description of all of the consequences of the Mergers and the Alternative Transaction and, in particular, may not address United States federal income tax considerations applicable to stockholders subject to special treatment under United States federal income tax law (including, for example, foreign persons, financial institutions, dealers in securities, insurance companies or tax-exempt entities, holders who acquired Berkshire Common Stock or General Re Voting Stock pursuant to the exercise of an employee stock option or right or otherwise as compensation, and holders who hold Berkshire Common Stock or General Re Voting Stock as part of a hedge, straddle or conversion transaction). In addition, no information is provided herein with respect to the tax consequences of the Mergers and the Alternative Transaction under applicable foreign, state or local laws. HOLDERS OF BERKSHIRE COMMON STOCK OR GENERAL RE VOTING STOCK ARE URGED TO CONSULT WITH THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE MERGERS AND THE ALTERNATIVE TRANSACTION TO THEM, INCLUDING THE EFFECTS OF FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.

The Mergers

If Berkshire does not make the Alternative Election (as defined above under "The Transactions--The Alternative Transaction"), either because it is not entitled to do so under the terms of the Merger Agreement or

36

because it expressly declines to make the Alternative Election, the parties will proceed with the Mergers, subject to the conditions described under the caption "Certain Provisions of the Merger Agreement--Conditions to Consummation of the Transactions."

If Berkshire does not make the Alternative Election, the respective obligations of each party to consummate the Mergers are conditioned upon one of the following having occurred: (i) Berkshire having received written notice of the issuance of the 351(e) Ruling and the No Gain or Loss Ruling; (ii) if the IRS will not grant the 351(e) Ruling as a result of the Treasury Department having withdrawn the Proposed Regulations, Berkshire having received written notice of the issuance of the No Gain or Loss Ruling or the
368(c) Ruling; or (iii) Berkshire having expressly declined to make the Alternative Election.

In addition, Berkshire's obligations to consummate the Mergers are further conditioned upon the following: (i) the Final Regulations (as defined in "Certain Provisions of the Merger Agreement--Conditions to Consummation of the Transactions") being in effect; (ii) either (A) Berkshire having received the
351(e) Ruling and the No Gain or Loss Ruling or (B) the Proposed Regulations having been withdrawn and Berkshire having received either the No Gain or Loss Ruling or the 368(c) Ruling; and (iii) Berkshire having received an opinion of Munger, Tolles & Olson LLP, counsel to Berkshire, based upon reasonably requested representation letters and dated the Closing Date, to the effect that the Berkshire Merger will be treated as a transfer of property to New Berkshire by the holders of Berkshire Common Stock governed by Section 351(a) or 351(b) of the Code. If Berkshire receives any of the Rulings, General Re's obligations to consummate the Mergers will be further conditioned upon the receipt by General Re of an opinion of Wachtell, Lipton, Rosen & Katz, counsel to General Re, based upon reasonably requested representation letters and dated the Closing Date, to the effect that the General Re Merger will be treated as a transfer of property to New Berkshire by the holders of General Re Common Stock governed by Section 351(a) of 351(b) of the Code.

Berkshire has received an opinion of Munger, Tolles & Olson LLP, dated the date of this Joint Proxy Statement/Prospectus, to the effect that, under currently applicable United States federal income tax law, the Berkshire Merger will be treated as a transfer of property to New Berkshire by the holders of Berkshire Common Stock governed by Section 351(a) or 351(b) of the Code. General Re has received an opinion of Wachtell, Lipton, Rosen & Katz, dated the date of this Joint Proxy Statement/Prospectus, to the effect that, under currently applicable United States federal income tax law, the General Re Merger will be treated as a transfer of property to New Berkshire by the holders of General Re Common Stock governed by Section 351(a) or 351(b). These opinions are based upon certain assumptions (including an assumption that the Rulings will be granted, as to which there can be no assurance) and certain representations made to Munger, Tolles & Olson LLP and Wachtell, Lipton, Rosen & Katz by Berkshire and General Re.

Based upon such opinions, if Berkshire receives the Rulings described above and the Mergers are consummated, the following United States federal income tax consequences will result:

(i) No gain or loss will be recognized by holders of Berkshire Common Stock or General Re Common Stock who exchange all of their Berkshire Common Stock or General Re Common Stock solely for New Berkshire Common Stock pursuant to the Mergers, except to the extent of any cash received in the General Re Merger in lieu of a fractional share interest in New Berkshire Common Stock;

(ii) No gain or loss will be recognized by New Berkshire as a result of the Mergers;

(iii) The aggregate tax basis of the shares of New Berkshire Common Stock received in the Berkshire Merger will be the same as the aggregate tax basis of the shares of Berkshire Common Stock surrendered in exchange therefor;

(iv) The aggregate tax basis of the shares of New Berkshire Common Stock received in the General Re Merger will be the same as the aggregate tax basis of the shares of General Re Common Stock surrendered in exchange therefor, decreased by the amount of cash received in lieu of a fractional share interest in New Berkshire Common Stock, and increased by the amount of income or gain which was recognized on such exchange; and

37

(v) The holding period of the shares of New Berkshire Common Stock received in the Mergers will include the holding period of the shares of Berkshire Common Stock or General Re Common Stock surrendered in exchange therefor.

A holder of General Re Common Stock who receives in the General Re Merger cash in lieu of a fractional share interest in New Berkshire Common Stock will recognize capital gain equal to the lesser of (i) the excess of (A) the sum of the fair market value of the shares of New Berkshire Common received in the Mergers and the amount of cash received in the General Re Merger in lieu of a fractional share interest in New Berkshire Common Stock over (B) such holder's basis in the shares of General Re Common Stock surrendered in the Merger or
(ii) the amount of cash so received, provided that as expected, immediately after the Effective Time, the General Re stockholders will not, in the aggregate, own stock of New Berkshire possessing 50% or more of the total combined voting power of all classes of New Berkshire stock entitled to vote or 50% or more of the total value of all classes of New Berkshire stock ("Section 304 Control"), taking into account certain constructive ownership rules of the Code and, in the case of a General Re shareholder who also owns Berkshire Common Stock, taking into account any New Berkshire Common Stock received by such General Re stockholder in the Berkshire Merger in its capacity as a Berkshire stockholder. Moreover, assuming that the General Re stockholders do not have Section 304 Control immediately after the Effective Time, no loss will be recognized by a General Re stockholder with respect to the receipt of cash in lieu of a fractional share interest in New Berkshire Common Stock. In the extremely unlikely event that the stockholders of General Re were to have Section 304 Control of New Berkshire immediately after the Effective Time, holders of General Re Common Stock who do not actually or constructively own any shares of Berkshire Common Stock at the Effective Time will recognize capital gain or loss equal to the difference between the amount of cash received in lieu of a fractional share interest in New Berkshire Common Stock and the portion of the General Re stockholder's tax basis in its General Re Common Stock that is allocable to such fractional share interest. Holders of General Re Common Stock who actually or constructively own shares of Berkshire Common Stock should consult their own tax advisors as to the amount and character of any income in the event that the General Re stockholders have Section 304 Control of New Berkshire immediately after the Effective Time.

Any capital gain or loss recognized on the receipt of cash in lieu of a fractional interest in New Berkshire Common Stock will be long-term capital gain or loss if the holder's holding period is more than one year at the Effective Time. In the case of individual holders, any such capital gain will be subject to tax at varying rates depending upon the holder's holding period and income level. The Code limits the deductibility of capital losses.

Shares of General Re Preferred Stock that are redeemed by General Re for cash immediately prior to the Effective Time will be subject to the rules of
Section 302 of the Code. Under Section 302 of the Code a redemption of shares of General Re Preferred Stock by General Re for cash will be treated as a distribution taxable as a dividend to the redeemed stockholders to the extent of General Re's current or accumulated earnings and profits unless the redemption (i) results in a "complete redemption" of the stockholder's interest in General Re, (ii) is "substantially disproportionate" with respect to the holder or (iii) is "not essentially equivalent to a dividend". In determining whether any of these three tests have been met, shares of General Re Common Stock will be taken into account along with shares of General Re Preferred Stock. Moreover, shares considered to be owned by the holder by reason of the constructive ownership rules of the Code, as well as shares actually owned, will be taken into account. If any of the foregoing tests are met, then, except with respect to declared and unpaid dividends, if any, the redemption of shares of General Re Preferred Stock for cash will result in taxable gain or loss equal to the difference between the amount of cash received and the holder's tax basis in the redeemed shares. Any such gain or loss will be capital gain or loss and will be long-term capital gain or loss if the stockholder's holding period exceeds one year. In the case of an individual, any such long-term capital gain will be taxed at varying rates depending upon the holder's holding period and income level. The Code limits the deductibility of capital losses. Based on a published IRS ruling, the redemption of a stockholder's General Re Preferred Stock for cash will be treated as "not essentially equivalent to a dividend" if, taking into account the constructive ownership rules, (a) the holder's relative stock interest in General Re is minimal, (b) the holder exercises no control over General Re's affairs and (c) there is a reduction in the holder's proportionate interest in General Re.

38

The Alternative Transaction

If Berkshire makes, or is deemed to have made, the Alternative Election, the parties will proceed with the Alternative Transaction, subject to the conditions described under the caption "Certain Provisions of the Merger Agreement--Conditions to Consummation of the Transactions."

If Berkshire makes, or is deemed to have made, the Alternative Election, Berkshire's obligation to consummate the Alternative Transaction is conditioned upon Berkshire's having received the opinions of Munger, Tolles & Olson LLP, counsel to Berkshire, and Wachtell, Lipton, Rosen & Katz, counsel to General Re, based upon reasonably requested representation letters and dated the Closing Date, that the Alternative Transaction will not qualify as a reorganization within the meaning of Section 368 of the Code, the Merger Consideration will be taxable to the stockholders of General Re, and the Alternative Transaction will not be a taxable transaction to either Berkshire or its stockholders.

Berkshire has received opinions of Munger, Tolles & Olson LLP and Wachtell, Lipton, Rosen and Katz, dated the date of this Joint Proxy Statement/Prospectus to the foregoing effect, in each case based upon certain assumptions and certain representations made to Munger, Tolles & Olson LLP and Wachtell, Lipton, Rosen & Katz by Berkshire and General Re.

Based upon such opinions, if the Alternative Election is made, the Alternative Transaction will not be taxable to Berkshire or its stockholders. The Alternative General Re Merger will, however, be a taxable transaction to the holders of General Re Common Stock. Each holder of General Re Common Stock will recognize gain or loss equal to the difference between (i) the sum of the fair market value of the shares of Berkshire Common Stock and the amount of cash received by such holder in the Alternative General Re Merger and (ii) such holder's tax basis in its shares of General Re Common Stock, provided that either (i) as expected, the stockholders of General Re do not have
Section 304 Control of Berkshire immediately after the Effective Time or
(ii) such holder does not actually or constructively own any shares of Berkshire Common Stock prior to the Effective Time. Such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the holder's holding period in the General Re Common Stock is more than one year at the Effective Time. Any such capital gain will be taxed at varying rates depending upon the holder's holding period and income level. The Code limits the deductibility of capital losses. Holders of General Re Common Stock who actually or constructively own shares of Berkshire Common Stock prior to the Effective Time should consult their own tax advisors as to the amount and character of any income in the extremely unlikely event that the General Re stockholders have Section 304 Control of Berkshire immediately after the Effective Time.

If the Alternative Election is made, the redemption of shares of General Re Preferred Stock by General Re for cash immediately prior to the Effective Time of the Alternative General Re Merger will be subject to Section 302 of the Code and will be taxed in the same manner described above with respect to redemptions of General Re Preferred Stock by General Re for cash immediately prior to the Effective Time of the General Re Merger.

CONFLICTS OF INTEREST

In considering the respective recommendations of the Berkshire Board and the General Re Board with respect to the Transactions, stockholders of Berkshire and General Re should be aware that, as described below, certain members of General Re's and Berkshire's management and Boards may have interests in the Transactions that are different from, or in addition to, the interests of stockholders of Berkshire and General Re, and that may create potential conflicts of interest. The Berkshire Board and the General Re Board have each considered these interests, among other matters, in approving and adopting the Merger Agreement and the Transactions.

Executive Officers and Board of New Berkshire. All of the current directors of Berkshire will become directors of New Berkshire. Following the Transactions, Ronald E. Ferguson, Chairman and Chief Executive Officer of General Re, will be appointed as a member of the New Berkshire Board of Directors. See "Directors

39

and Officers of New Berkshire Following the Mergers." In addition, the executive officers of Berkshire will become the executive officers of New Berkshire.

Employment Agreement. In connection with the execution of the Merger Agreement, General Re and New Berkshire entered into an employment agreement with Ronald E. Ferguson (the "Employment Agreement"). The Employment Agreement is for a term of five years, commencing at the Effective Time and terminating on the fifth anniversary thereof (the "Employment Period"). During the Employment Period, Mr. Ferguson will serve as the Chairman and Chief Executive Officer of General Re, reporting directly to the Chief Executive Officer of New Berkshire. During the Employment Period, Mr. Ferguson will also serve on the Board of Directors of New Berkshire and have an annual base salary of not less than the annual base salary payable to Mr. Ferguson prior to the Effective Time and an annual bonus pursuant to the terms of the annual bonus and long-term incentive compensation plans for senior executives of General Re. The Employment Agreement provides that upon Mr. Ferguson's termination of employment, he will be paid an annual retirement benefit pursuant to the Employee Retirement Plan of General Re and its Affiliates (the "Retirement Plan") and the General Re Supplemental Benefits Equalization Plan, calculated without an actuarial reduction as if Mr. Ferguson had remained employed until his Normal Retirement Date (as defined in the Retirement Plan) (the "Retirement Benefit"). During the Employment Period, Mr. Ferguson will be eligible to receive benefits which are no less favorable in the aggregate than the benefits he received prior to the Effective Time. The Employment Agreement further provides that, upon the termination of Mr. Ferguson's employment other than for cause, death or disability or if Mr. Ferguson terminates employment for good reason, Mr. Ferguson is entitled to a lump-sum cash payment equal to the sum of (i) any unpaid base salary, (ii) a pro rata annual bonus, based on the average of the annual bonuses earned in the three years prior to the date of termination (the "Average Annual Bonus") and (iii) the product of (x) the greater of (A) three and (B) the number of months from the date of termination until the end of the Employment Period divided by 12 (the "Continuation Period") and (y) the sum of Mr. Ferguson's base salary and the Average Annual Bonus. Upon any such termination, any incentive compensation awards granted after the Effective Time will vest immediately, and the Retirement Benefit will be calculated to include the additional age and service credit that Mr. Ferguson would have accrued if he had remained employed during the Continuation Period. In addition, Mr. Ferguson will continue to be provided with benefits during the Continuation Period. If any amounts payable to Mr. Ferguson under the Employment Agreement or otherwise would subject him to the excise tax under Section 4999 of the Code, General Re will make a payment to Mr. Ferguson such that after the payment of all income and excise taxes, he will be in the same after-tax position as if no excise tax under Section 4999 had been imposed. The Employment Agreement contains restrictive covenants, which prohibit Mr. Ferguson from competing with General Re, soliciting its employees, and disclosing confidential information, during the Employment Period and for specified periods thereafter. The Employment Agreement contains substantially the same terms as the Ferguson Agreements (as defined below) and replaces and supersedes the Ferguson Agreements.

Change of Control Arrangements. Mr. Ferguson is a party to an employment and a change of control agreement with General Re (the "Ferguson Agreements"), both of which will be superseded by the Employment Agreement described above and, as such, Mr. Ferguson will not be entitled to receive the payments and benefits described herein. James E. Gustafson, Tom N. Kellogg and certain other senior management employees of General Re (together with Mr. Ferguson, the "Covered Executives") are parties to change of control employment agreements with General Re (together with the Ferguson Agreements, the "Executive Agreements"). The Executive Agreements provide that if within two years following a change of control of General Re, a Covered Executive's employment is terminated other than for cause, death or disability or the Covered Executive terminates his employment for good reason, such Covered Executive will be entitled to receive a lump sum payment equal to the product of (i) three and (ii) the sum of (A) the Covered Executive's annual base salary and (B) the greater of (x) 50% of the annual base salary and (y) the target formula amount of the annual incentive bonus under the General Re 1995 Long Term Compensation Plan for the calendar year in which the date of termination occurs. In addition, the Covered Executive will be entitled to continued coverage under General Re's welfare benefit plans or the cost of providing such benefits. Under the Ferguson Agreements, Mr. Ferguson would have been entitled to an unreduced normal retirement pension benefit. Stockholder approval

40

of the Transactions contemplated by the Merger Agreement will constitute a Change of Control for purposes of the Executive Agreements. If any amounts payable to a Covered Executive under the Executive Agreements or otherwise would subject such executive to the excise tax under Section 4999 of the Code, General Re will make a payment to the Covered Executive such that after the payment of all income and excise taxes, the Covered Executive will be in the same after-tax position as if no excise tax under Section 4999 had been imposed.

Long-Term Compensation Programs. Stockholder approval of the Transactions will constitute a change in control under General Re's 1989 Long-Term Compensation Plan, as amended (the "1989 Plan") and the 1995 Long-Term Compensation Plan, as amended (the "1995 Plan"). Prior to a change in control, each participant in the 1989 Plan and the 1995 Plan, including certain executive officers, who is eligible to receive a long-term performance bonus under the 1989 Plan or 1995 Plan and/or an annual incentive bonus under the 1995 Plan shall elect that any such long-term performance bonus and/or annual incentive bonus will either (i) become immediately payable or creditable, where applicable, based upon the assumption that the applicable performance objectives have been fully achieved (or, in the case of the long-term performance bonus, if greater, on actual performance achieved), and pro-rated based on a fraction, the numerator of which will be the number of days in the award period that have elapsed prior to the occurrence of such change in control, and the denominator of which will be the total number of days in the award period, or (ii) continue to be earned without interruption based on continuing employment for the full award period, pursuant to the terms of the original award with a minimum award of not less than the pro rated award. In addition, prior to a change in control, each participant in the 1995 Plan and/or General Re's Share Partnership Program, including certain executive officers, who has elected to defer amounts otherwise payable as long-term performance bonus or annual incentive bonus shall have the right to elect that all such amounts deferred into stock units will either (i) become immediately payable in cash in a lump-sum or (ii) continue to be deferred and converted into share units with respect to Berkshire Class B Common Stock.

Directors Plans. Stockholder approval of the Transactions will constitute a change in control under General Re's Deferred Compensation Plan for Directors (the "Deferred Compensation Plan"). Upon a change in control, the account balance of a participating director, at the election of the director, may be distributed immediately or may continue to be deferred in accordance with a director's original election. In addition, pursuant to the terms of General Re's Retirement Plan for Directors (as amended and restated), Directors' Stock Unit Plan, 1989 Long-Term Compensation Plan and 1995 Long-Term Compensation Plan (the "Director Plans"), a cessation of service from the General Re Board of Directors, as a result of the General Re Merger will be deemed to be a "Retirement" within the meaning of each such Director Plan for all purposes of such Director Plans, without regard to the director's actual age or years of service upon any such cessation of service. In addition, upon cessation of service entitling such former directors to payments thereunder from the General Re Board as a result of the Transactions, the restrictions on the shares of restricted stock granted under Director Plans will lapse.

Stock-Based Rights. As described under "The Transactions--Effect on General Re Stock Plans" above, pursuant to terms of the General Re Stock Plans, unvested stock options and stock appreciation rights granted prior to June 9, 1998, including those held by executive officers, will become fully vested and exercisable as a result of stockholder approval of the Transactions. In addition, upon certain terminations of employment within two years following the General Re Merger, the restrictions on the shares of restricted stock and share units held by employees, including certain executive officers, will lapse. The number of unvested stock options to acquire shares of General Re Common Stock held by Messrs. Ferguson, Gustafson, Kellogg, Minton and Dr. Lutke-Bornefeld that will become fully vested and exercisable as a result of the Transactions is 214,432, 57,534, 38,907, 6,085 and 24,000, respectively. The number of shares of General Re Common Stock underlying awards of restricted stock and share units held by Messrs. Ferguson, Gustafson, Kellogg, Minton and Dr. Lutke-Bornefeld that may become transferable as a result of the Transactions is 26,955.55, 23,946.87, 9,347.41, 2,000.00 and 13,367.21, respectively.

Indemnification. The Merger Agreement also provides that from and after the Effective Time, New Berkshire and General Re will indemnify, defend, protect and hold harmless the present and former officers and

41

directors of General Re, subject to certain limitations, for all claims arising as a result of their service to General Re or relating to the Merger Agreement and the Transactions. See "Certain Provisions of The Merger Agreement--Indemnification."

CERTAIN EMPLOYEE BENEFIT MATTERS

The Merger Agreement provides generally that the current General Re employee benefit plans will, to the extent practicable and except as necessary or desirable to facilitate compliance with applicable statutory and regulatory requirements and their terms, remain in effect without material amendment through the consummation of the Transactions and (other than the General Re Stock Plans) for a period of at least three years thereafter. However, New Berkshire, Berkshire and General Re will not be required to issue any shares of its equity securities in connection with such plans following the consummation of the Transactions other than with respect to unexercised stock options (including replacement options) to purchase outstanding shares of General Re Common Stock and existing share units (payable in shares of General Re Common Stock) that are converted into rights with respect to New Berkshire Common Stock upon consummation of the Transactions. See "The Transactions-- Effect on General Re Stock Plans." General Re and Berkshire will use their reasonable best efforts to agree on compensation plans for the officers and employees of General Re after consummation of the Transactions to provide them incentive compensation for a period of at least three years thereafter that in the aggregate is reasonably comparable (without giving effect to any payments resulting from the Transactions) to that historically provided by the General Re Stock Plans.

The Merger Agreement also provides that New Berkshire or Berkshire, as the case may be, will honor without material modification for a period of at least three years following consummation of the Transactions all current employee severance plans or policies and employment and severance agreements of General Re.

ACCOUNTING TREATMENT

The General Re Merger will be accounted for under the purchase method of accounting, in accordance with generally accepted accounting principles. Under the purchase method of accounting, the purchase price of General Re, including direct costs of the Transactions, will be allocated to the assets acquired and liabilities assumed based upon their estimated fair values, with the excess purchase consideration allocated to goodwill. The conversion of Berkshire Common Stock into New Berkshire Common Stock will be treated as a reorganization with no change in the recorded amount of Berkshire's assets and liabilities. The financial statements of Berkshire will become the financial statements of New Berkshire. The results of New Berkshire operations will include the results of operations of General Re commencing at the Effective Time.

The Unaudited Pro Forma Combined Condensed Financial Statements appearing elsewhere in this Joint Proxy Statement/Prospectus are based upon certain assumptions and allocate the purchase price to assets and liabilities based upon preliminary estimates of their respective fair values. The unaudited pro forma adjustments and combined amounts are included for informational purposes only. If the Transactions are consummated, then New Berkshire's financial statements will reflect effects of acquisition adjustments only from the Effective Time. The actual allocation of the purchase price may differ significantly from the allocation reflected in the Unaudited Pro Forma Combined Condensed Financial Statements.

APPROVALS AND CONSENTS

The Merger Agreement provides that General Re and Berkshire will use their best efforts and cooperate with one another (i) in promptly determining whether any filings are required to be made or consents, approvals, waivers, permits or authorizations are required to be obtained under any applicable law or regulation or from any governmental authorities or third parties in connection with the transactions contemplated by the Merger Agreement and the Stock Option Agreement and (ii) in promptly making any such filings, in furnishing information required in connection therewith and in timely seeking to obtain any such consents, approvals, waivers, permits or authorizations.

42

U. S. Antitrust Laws

Under the HSR Act, certain acquisition transactions may not be consummated unless notice has been given and certain information furnished to the Antitrust Division of the United States Department of Justice (the "Antitrust Division") and the FTC and specified waiting period requirements have been satisfied, unless earlier termination has been granted. General Re and Berkshire each filed with the Antitrust Division and the FTC a Notification and Report Form with respect to the Mergers on July 9, 1998 and July 10, 1998, respectively. On August 9, 1998, the waiting period under the HSR Act expired. At any time before or after the Effective Time, and notwithstanding that the HSR Act waiting period has been terminated, the Antitrust Division could take such action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin consummation of the Mergers or seeking divestiture of substantial assets of Berkshire or General Re. At any time before or after the Effective Time, and notwithstanding that the HSR Act waiting period has been terminated, any state could take such action under the antitrust laws as it deems necessary or desirable in the public interest. Such action could include seeking to enjoin consummation of the Merger or divestiture of businesses of Berkshire or General Re. Private parties also may seek to take legal action under the antitrust laws under certain circumstances.

State Insurance Regulatory Approvals

State insurance company holding laws and regulations applicable to General Re generally provide that no person may acquire control of certain General Re insurance subsidiaries unless such person has provided certain required information to, and such acquisition has been approved by, the appropriate insurance regulatory authorities. In accordance with these laws, an application on Form A for approval of the Transactions has been filed with the Commissioners of Insurance of the States of Connecticut, Delaware, Ohio and North Dakota. As of the date of this Joint Proxy Statement/Prospectus, these Commissioners of Insurance have not completed their respective review of Berkshire's applications.

Foreign Insurance and Securities Broker-Dealer Regulatory Approvals

The insurance company or securities broker-dealer laws of Australia, Hong Kong, South Africa and the United Kingdom generally provide that no person may acquire control of General Re or of certain General Re insurance subsidiaries unless such person has provided certain required information to, and such acquisition has been approved by, the appropriate regulatory authorities of that country. In accordance with the laws of these countries, Berkshire has filed an application for approval of the Transactions with the appropriate governmental entities in each country. As of the date of this Joint Proxy Statement/Prospectus, these countries' respective governments have not completed their review of Berkshire's filings.

European Economic Community Merger Approval

The acquisition by New Berkshire of the voting securities of General Re pursuant to the Merger Agreement is subject to disapproval by the European Commission. In accordance with the Regulation 4064/89 as amended, promulgated by the Council of the European Union and generally known as the Merger Regulation, Berkshire and General Re have filed a draft Application Form CO with the European Commission notifying the Commission of the proposed Merger. As of the date of this Joint Proxy Statement/Prospectus, the Commission is reviewing the draft filing.

STOCK EXCHANGE LISTING

Berkshire will use its best efforts to cause the shares of New Berkshire Common Stock issued in the Mergers to be approved for listing on the NYSE, subject to notice of issuance, prior to the Closing Date.

DELISTING AND DEREGISTRATION OF GENERAL RE COMMON STOCK

If the General Re Merger is consummated, General Re Common Stock will be delisted from the NYSE and deregistered under the Exchange Act.

43

RESALES OF COMMON STOCK

Shares of Class A Common Stock and Class B Common Stock to be issued in connection with the Mergers will be registered under the Securities Act of 1933, as amended (the "Securities Act"). Such shares will be freely transferable, except that shares received by any person who may be deemed to be an affiliate of General Re or Berkshire within the meaning of Rule 145 of the Securities Act (each such person being an "Affiliate") may not be resold except in transactions permitted by such Rule or as otherwise permitted under the Securities Act.

General Re has agreed in the Merger Agreement to use its best efforts to cause each person who may be deemed to be an Affiliate of General Re to deliver to Berkshire a written agreement intended to ensure compliance with the Securities Act.

APPRAISAL RIGHTS

General Re

Record holders of shares of General Re Common Stock will not be entitled to appraisal rights under Section 262 of the DGCL in connection with the General Re Merger. However, record holders of General Re Common Stock will be entitled to such appraisal rights with respect to the Alternative General Re Merger if the Alternative Transaction is consummated. The following discussion is not a complete statement of the law pertaining to appraisal rights under the DGCL and is qualified in its entirety by reference to the full text of Section 262, which is reprinted as Annex IX to this Joint Proxy Statement/Prospectus.

Under the DGCL, record holders of General Re Common Stock who do not wish to accept the Berkshire Common Stock and cash upon consummation of the Alternative General Re Merger, who follow the procedures set forth in Section 262, and who have not voted in favor of the Transactions, will be entitled to have their shares of General Re Common Stock appraised by the Delaware Court of Chancery and to receive payment for the "fair value" of such shares, exclusive of any element of value arising from the accomplishment or expectation of the Alternative Transaction, together with a fair rate of interest, as determined by such court, if the Alternative Transaction is consummated.

Pursuant to Section 262, General Re must provide not less than 20 days notice of the General Re Special Meeting to all persons who held shares of General Re Common Stock on the Record Date, and such notice must state that such appraisal rights are available and include a copy of Section 262. This Joint Proxy Statement/Prospectus constitutes such notice for purposes of the General Re Special Meeting. Any stockholder of record who wishes to exercise appraisal rights should review the following discussion and Annex IX carefully because failure to comply timely and properly with the procedures specified in
Section 262 will result in the loss of appraisal rights under the DGCL.

A holder of General Re Common Stock wishing to exercise appraisal rights must deliver to General Re, before the vote on the approval and adoption of the Merger Agreement at the General Re Special Meeting, a written demand for appraisal of such holder's shares of General Re Common Stock. A proxy or vote against the Transactions will not constitute such a demand. Failure to vote against the Transactions will not constitute a waiver of the holder's appraisal rights, but a vote in favor of the Transactions will constitute such a waiver. In addition, a holder of General Re Common Stock wishing to exercise appraisal rights must hold of record such General Re Common Stock on the date that written demand therefor is made and continue to hold such shares of General Re Common Stock through the Effective Time.

All written demands for appraisal of shares of General Re Common Stock should be mailed or delivered to General Re Corporation, 695 East Main Street, Stamford, Connecticut 06904, Attention: Corporate Secretary.

Within 10 days after the Effective Time of the Alternative General Re Merger, General Re must send a notice as to the effectiveness of the Alternative General Re Merger to each person who has satisfied the appropriate provisions of Section 262. Within 120 days after such Effective Time, but not thereafter, General Re

44

or any such stockholder who has satisfied the foregoing conditions and is otherwise entitled to appraisal rights under Section 262, may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares of General Re Common Stock held by such stockholder. Upon the filing of any such petition by a stockholder, service of a copy of the petition must be made to General Re. If no such petition is filed, appraisal rights will be lost for all stockholders who had previously demanded appraisal of their shares of General Re Common Stock. Stockholders of General Re seeking to exercise appraisal rights should assume that General Re will not file a petition with respect to the appraisal of the value of shares of General Re Common Stock and that General Re will not initiate any negotiations with respect to the "fair value" of shares of General Re Common Stock. Accordingly, stockholders of General Re who wish to exercise their appraisal rights should regard it as their obligation to take all steps necessary to perfect their appraisal rights in the manner described in Section 262.

Within 120 days after the Effective Time of the Alternative General Re Merger, any record holder of shares of Common Stock who has complied with the provisions of Section 262 will be entitled, upon written request, to receive from General Re a statement setting forth the aggregate number of shares of General Re Common Stock not voted in favor of approval of the Merger Agreement and with respect to which demands for appraisal were received by General Re, and the number of holders of such shares of General Re Common Stock.

If a petition for appraisal is timely filed, after a hearing on such petition, the Delaware Court of Chancery will determine the holders of shares of General Re Common Stock entitled to appraisal rights and will appraise the "fair value" of the shares of General Re Common Stock, exclusive of any element of value arising from the accomplishment or expectation of the Alternative Transaction, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. Stockholders seeking appraisal should be aware that the fair value of their shares of General Re Common Stock as determined under Section 262 could be more than, the same as or less than the value of the value of the Berkshire Common Stock and cash that they would otherwise receive if they did not seek appraisal.

Any stockholder of General Re who has duly demanded an appraisal in compliance with Section 262 will not, after the Effective Time of the Alternative General Re Merger, be entitled to vote such holder's shares of General Re Common Stock for any purpose nor, after such Effective Time, be entitled to the payment of dividends or other distributions thereon.

If no petition for an appraisal is filed within the time provided, or if a stockholder of General Re delivers to General Re a written withdrawal of such holder's demand for an appraisal and an acceptance of the merger consideration within 60 days after the Effective Time of the Alternative General Re Merger or with the written approval of General Re thereafter, then the right of such stockholder to an appraisal will cease and such stockholder shall be entitled to receive the merger consideration with respect to such stockholders shares of General Re Common Stock, without interest, as if such stockholder had not demanded appraisal of such holder's shares of General Re Common Stock.

Berkshire. Under the DGCL, holders of Berkshire Common Stock are not entitled to dissenters' appraisal rights, which would give them the right to obtain the payment of cash in exchange for their shares of Berkshire Common Stock as a result of the Berkshire Merger. Such rights are unavailable because the Berkshire Common Stock is listed on the NYSE and the consideration such holders will own after the Berkshire Merger will be shares of New Berkshire Common Stock. Holders of Berkshire Common Stock are also not entitled to such appraisal rights in the event the Alternative Transaction is consummated.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

Berkshire and General Re have each made forward-looking statements in this document (and in certain documents that are incorporated by reference in this Joint Proxy Statement/Prospectus) that are subject to risks and uncertainties. These statements are based on the beliefs and assumptions of the respective company's management, and on information currently available to such management. Forward-looking statements include

45

the information concerning possible or assumed future results of operations of Berkshire, General Re and New Berkshire set forth under "Summary," "The Transactions--Background of the Transactions," "The Transactions--Reasons for the Transactions; Recommendations of the Boards of Directors" and "Unaudited Pro Forma Condensed Combined Financial Statements," and statements preceded by, followed by or that include the words "believes," "expects," "anticipates," "intends," "plans," "estimates" or similar expressions.

Forward-looking statements are not guarantees of performance. They involve risks, uncertainties and assumptions. The future results and stockholder values of the combined companies following the Transactions may differ materially from those expressed in these forward-looking statements. Many of the factors that will determine these results and values are beyond Berkshire's, General Re's, and New Berkshire's ability to control or predict. Stockholders are cautioned not to place undue reliance on any forward-looking statements. In addition, Berkshire, General Re and New Berkshire do not have any intention or obligation to update forward-looking statements after they distribute this Joint Proxy Statement/Prospectus, even if new information, future events or other circumstances have made them incorrect or misleading. Berkshire, General Re and New Berkshire claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Actual events and results may differ materially from those expressed or forecasted in forward-looking statements due to a number of factors. The principal important risk factors that could cause the combined companies' actual performance and future events and actions to differ materially from such forward-looking statements, include, but are not limited to, changes in market prices of Berkshire's significant investees, the occurrence of one or more catastrophic events, such as an earthquake or hurricane, that causes losses insured by General Re or members of Berkshire's insurance group, changes in insurance laws or regulations, changes in Federal income tax laws, as well as general economic and market factors that affect the prices of securities or the industries in which Berkshire and their affiliates do business, especially those affecting the property and casualty insurance industry.

RECORD DATE; VOTING POWER

General Re. The General Re Board has fixed the close of business (5:00 p.m., New York City time) on August 10, 1998 (the "Record Date") as the record date for determining the holders of General Re Voting Stock entitled to notice of, and to vote at, the General Re Meeting. Only holders of record of General Re Voting Stock at the close of business on the Record Date will be entitled to notice of, and to vote at, the General Re Meeting.

At the close of business on the Record Date, (i) 75,664,527 shares of General Re Common Stock were issued and outstanding and entitled to vote at the General Re Meeting; and (ii) 1,690,554 shares of General Re Preferred Stock were issued and outstanding and entitled to vote at the General Re Meeting. Holders of record of General Re Common Stock and General Re Preferred Stock are entitled to one vote at the General Re Meeting for each share of General Re Common Stock held of record on the Record Date or underlying such General Re Preferred Stock on any matter which may properly come before the General Re Meeting. Votes may be cast at the General Re Meeting in person or by proxy. See "The Stockholders' Meetings--Voting of Proxies."

The presence at the General Re Meeting, either in person or by proxy of the holders of a majority of the voting power represented by the General Re Voting Stock is necessary to constitute a quorum in order to transact business at the General Re Meeting. In the event that a quorum is not present at the General Re Meeting, such meeting will be adjourned or postponed in order to solicit additional proxies.

Berkshire. The Berkshire Board has fixed the close of business (5:00 p.m., New York City time) on August 10, 1998 as the record date for determining the holders of Berkshire Common Stock entitled to notice of, and to vote at, the Berkshire Meeting. Only holders of record of Berkshire Common Stock at the close of business on the Record Date will be entitled to notice of, and to vote at, the Berkshire Meeting.

Votes may be cast at the Berkshire Meeting in person or by proxy. See "The Stockholders' Meetings--Voting of Proxies."

47

The presence at the Berkshire Meeting, either in person or by proxy of the holders of a majority of the outstanding Berkshire Common Stock entitled to vote, is necessary to constitute a quorum of the Berkshire Common Stock, in order to transact business at the Berkshire Meeting. In the event that a quorum is not present at the Berkshire Meeting, it is expected that such meeting will be adjourned or postponed in order to solicit additional proxies.

VOTES REQUIRED

General Re. Approval of the proposal to adopt the Merger Agreement and the Transactions, including the General Re Merger and the Alternative Transaction and the Alternative General Re Merger, will require the affirmative vote of the majority of the voting power of the outstanding shares of General Re Voting Stock entitled to vote thereon. Under applicable Delaware law, in determining whether the proposal to approve and adopt the Merger Agreement and the Transactions has received the requisite number of affirmative votes, abstentions will be counted and have the same effect as a vote against the proposals. Brokers who hold shares of General Re Voting Stock as nominees, in the absence of instructions from the beneficial owners thereof, will not have discretionary authority to vote such shares for the approval and adoption of the Merger Agreement and the Transactions. Any shares which are not voted because the nominee-broker lacks discretionary authority will be counted and have the same effect as a vote against the proposals.

Berkshire. Approval of each of the proposals to (a) adopt the Merger Agreement and the Transactions, including the Berkshire Merger and the Alternative Transaction and (b) approve the Berkshire Charter Amendment, will require the affirmative vote of the majority of the voting power of the outstanding shares of Berkshire Common Stock entitled to vote thereon. Under applicable Delaware law, in determining whether either proposal has received the requisite number of affirmative votes, abstentions will be counted and have the same effect as a vote against the proposal. Brokers who hold shares of Berkshire Common Stock as nominees, in the absence of instructions from the beneficial owners thereof, will not have discretionary authority to vote such shares for the approval and adoption of the Merger Agreement and the Transactions. Any shares which are not voted because the nominee-broker lacks such discretionary authority will be counted and have the same effect as a vote against the proposal. However, even in the absence of instructions from the beneficial owners thereof, brokers who hold shares of Berkshire Common Stock as nominees will have discretionary authority to vote such shares for the approval of the Berkshire Charter Amendment.

SHARE OWNERSHIP OF MANAGEMENT AND CERTAIN STOCKHOLDERS

General Re. As of the close of business on the Record Date, General Re's directors and executive officers and their affiliates may be deemed to be the beneficial owners of 271,704 outstanding shares of General Re Common Stock (collectively representing approximately 0.35% of the voting power of the General Re Voting Stock).

Berkshire. As of the close of business on the Record Date, Berkshire's directors and executive officers and their affiliates may be deemed to be the beneficial owners of 546,770 outstanding shares of Berkshire Class A Common Stock and 92 outstanding shares of Berkshire Class B Common Stock (collectively representing approximately 45.7% of the voting power of the Berkshire Common Stock). See "The Transactions--Other Agreements--Voting Agreements."

VOTING OF PROXIES

Shares represented by properly executed proxies received in time for a Special Meeting will be voted at such Special Meeting in the manner specified by such proxies. Berkshire stockholders should be aware that, if your proxy is properly executed but does not contain voting instructions, your proxy will be voted FOR approval of the Merger Agreement, including the Transactions and the Alternative Transaction and FOR approval of the Berkshire Charter Amendment. General Re stockholders should be aware that, if your proxy is properly executed but does not contain voting instructions, your proxy will be voted FOR approval of the Merger Agreement,

48

including the Transactions and the Alternative Transaction. It is not expected that any matter other than as described herein will be brought before the Special Meetings. If other matters are properly presented before the Special Meetings, the persons named in such proxy will have authority to vote in accordance with their judgment on any other such matter, including without limitation, any proposal to adjourn or postpone the meeting or otherwise concerning the conduct of the meeting; provided, that a proxy that has been designated to vote against the approval of the Merger Agreement will not be voted, either directly or through a separate proposal, to adjourn the meeting to solicit additional votes.

REVOCABILITY OF PROXIES

The grant of a proxy on the enclosed Berkshire or General Re proxy card does not preclude a stockholder from voting in person. A stockholder of General Re may revoke a proxy at any time prior to its exercise by (i) delivering, prior to the General Re Special Meeting, to Charles F. Barr, Secretary, General Re Corporation, 695 East Main Street, Stamford, Connecticut 06904, a written notice of revocation bearing a later date or time than the proxy; (ii) delivering to the Secretary of General Re a duly executed proxy bearing a later date or time than the revoked proxy; or (iii) attending the General Re Meeting and voting in person. A stockholder of Berkshire may revoke a proxy at any time prior to its exercise by (i) delivering, prior to the Berkshire Special Meeting, to Forrest N. Krutter, Secretary, Berkshire Hathaway Inc., 1440 Kiewit Plaza, Omaha, Nebraska 68131, a written notice of revocation bearing a later date or time than the proxy; (ii) delivering to the Secretary of Berkshire a duly executed proxy bearing a later date or time than the revoked proxy; or (iii) attending the Berkshire Meeting and voting in person. Attendance at the relevant Special Meeting will not by itself constitute revocation of a proxy. Neither Berkshire nor General Re expects to adjourn the relevant Special Meeting for a period of time long enough to require the setting of a new Record Date for such meeting. If an adjournment occurs, it will have no effect on the ability of either Berkshire's or General Re's stockholders of record as of the Record Date to exercise their voting rights or to revoke any previously delivered proxies.

SOLICITATION OF PROXIES

Each of Berkshire and General Re will bear the cost of solicitation of proxies from its own stockholders, except that General Re and Berkshire intend to share equally the cost associated with this Joint Proxy Statement/Prospectus, including related filing fees. Arrangements will be made with brokerage houses and other custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of stock held of record by such persons, and Berkshire and General Re will reimburse such company's custodians, nominees and fiduciaries for their reasonable out-of- pocket expenses in connection therewith. In addition to solicitation by mail, the directors, officers and employees of General Re and its subsidiaries may solicit proxies from General Re stockholders by telephone, telegram or in person.

In addition, General Re has retained Georgeson & Company Inc. to assist them in the solicitation of proxies from stockholders in connection with the General Re Meeting. Georgeson & Company Inc. will receive a fee which General Re expects will not exceed $15,000 as compensation for its services and will also receive reimbursement of its out-of-pocket expenses. General Re has agreed to indemnify Georgeson & Company Inc. against certain liabilities arising out of or in connection with its engagement.

GENERAL RE STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY CARDS. IN NO EVENT SHOULD BERKSHIRE STOCKHOLDERS SEND IN THEIR STOCK CERTIFICATES.

(viii) the representations and warranties of the other party in the Merger Agreement being true and correct in all material respects, in each case as of the date of the Merger Agreement and as of the Closing Date as though made on and as of such date; provided that for purposes of determining the satisfaction of the foregoing, such representations and warranties will be deemed true and correct if the failure or failures of such representations and warranties to be so (excluding the effect of any qualification set forth therein relating to "materiality", "material adverse change" or "material adverse effect") have not had and could not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the other party or on the ability of the other party to consummate the Transactions or to perform its obligations under the Merger Agreement; and

50

(ix) each party having performed the obligations required to be performed by it under the Merger Agreement at or prior to the Closing Date (except for such failures to perform as have not had or could not reasonably be expected, either individually or in the aggregate, to have a material adverse effect with respect to the other party or adversely affect the ability of the party to consummate the transactions therein contemplated or perform its obligations thereunder).

(ii) if there has been an Alternative Election, Berkshire having received the opinions of Munger, Tolles & Olson LLP, counsel to Berkshire, and Wachtell, Lipton, Rosen & Katz, counsel to General Re, based upon reasonably requested representation letters and dated the Closing Date, that the Alternative Transaction will not qualify as a reorganization within the meaning of Section 368 of the Code, the Merger Consideration will be taxable to the stockholders of General Re, and the Alternative Transaction will not be a taxable transaction to either Berkshire or its stockholders; and

The "Final Regulations" means Treasury Regulation Section 1.351-1(c) as in effect on the date of the Merger Agreement (or as may be amended prior to the Closing Date either (1) in a manner affecting only the diversification test of Treasury Regulation Section 1.351-1(c)(1)(i) and not the test of Treasury Regulation Section 1.351-1(c)(1)(ii) or (2) solely to conform the Final Regulations to the amendments made to Section 351(e)(1) of the Code by the Taxpayer Relief Act of 1997).

CONDUCT OF BUSINESS PENDING THE EFFECTIVE TIME

Pursuant to the Merger Agreement, General Re has agreed, among other things, until the Effective Time (except as otherwise specifically required by the terms of the Merger Agreement) that it will, and it will cause its subsidiaries to, act and carry on their respective businesses in the usual, regular and ordinary course of business consistent with past practice and, to the extent consistent therewith, use its best efforts to preserve intact their current business organizations, keep available the services of their current officers and employees and preserve their relationships with insureds, reinsurers, customers, suppliers, insurance brokers and agents, and others having business dealings with them so that their goodwill and ongoing businesses will not be impaired at the Effective Time. Except for certain exceptions for actions in the ordinary course of business consistent with past practices or as disclosed to Berkshire, General Re agreed to not, and not permit any of its subsidiaries to, without prior consent of Berkshire, among other things, (i) declare or pay any dividend or distribution (other than regular quarterly cash dividends on General Common Stock not in excess of $0.59 per share, with usual record and payment dates for such dividends in accordance with General Re's past dividend practice, and regular annual cash dividends on General Re Preferred Stock not in excess of $6.20 per share (or not in excess of the amount

51

required to be paid pursuant to the Certificate of Designations for the General Re Preferred Stock, with usual record and payment date for such dividends in accordance with such Certificate of Designations)), (ii) reclassify or acquire any shares of its capital stock or certain other securities, (iii) issue or encumber any shares of its capital stock and certain other securities, (iv) amend its charter documents, (v) acquire a substantial portion of the stock or assets of another business organization,

NO SOLICITATION

The Merger Agreement provides that neither General Re nor any of its subsidiaries will, nor will General Re authorize or permit any of its directors, officers or employees or any investment banker, financial advisor, attorney, accountant or other representative retained by it or any of its subsidiaries to, directly or indirectly through another person, (i) solicit, initiate or encourage (including by way of furnishing information), or take any other action designed to facilitate, any inquiries or the making of any inquiry, proposal or offer from any person relating to any direct or indirect acquisition or purchase of a business that constitutes 20% or more of the net revenues, net income or assets of General Re and its subsidiaries, taken as a whole, or 20% or more of any class of equity securities of General Re, any tender offer or exchange offer that if consummated would result in any person beneficially owning 20% or more of any class of any equity securities of General Re, or any merger, consolidation, business combination, recapitalization, reorganization, liquidation, dissolution or similar transaction involving General Re (or any General Re subsidiary whose business constitutes 20% or more of the net revenues, net income or assets of General Re and its subsidiaries, taken as a whole), other than the transactions contemplated by the Merger Agreement or the Stock Option Agreement (a "Takeover Proposal") or (ii) participate in any discussions or negotiations regarding any Takeover Proposal.

Notwithstanding the foregoing, however, if the General Re Board of Directors determines in good faith, after consultation with outside counsel, that it is necessary to do so in order to act in a manner consistent with its fiduciary duties to General Re's stockholders under applicable law, General Re may, in response to any proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, reorganization, liquidation, dissolution or similar transaction, for consideration to General Re's stockholders consisting of cash and/or securities, all of the shares of General Re's capital stock then outstanding or all or substantially all the assets of General Re, on terms which the Board of Directors of General Re determines in its good faith judgment to be more favorable to General Re's stockholders than the Transactions and for which financing, to the extent required, is then committed or which, in the good faith judgment of the Board of Directors of General Re, is reasonably capable of being obtained by such third party (a "Superior Proposal") made prior to the approval of the Transactions by the General Re stockholders, which Superior Proposal was not solicited by it and which did not otherwise result from a breach of the covenant not to solicit, and subject to providing prior written notice of its decision to take such action to Berkshire and compliance with the other provisions of the covenant not to solicit, (x) furnish information with respect to General Re and its subsidiaries to any person making a Superior Proposal pursuant to a customary confidentiality agreement (as determined by General Re based on the advice of its outside counsel) and (y) participate in discussions or negotiations regarding such Superior Proposal.

Except as expressly permitted by the covenant not to solicit, neither the Board of Directors of General Re nor any committee thereof may (i) withdraw or modify, or propose publicly to withdraw or modify, in a manner

52

adverse to Berkshire, the approval or recommendation by such Board of Directors or such committee of the Transactions or this Agreement, (ii) approve or recommend, or propose publicly to approve or recommend, any Takeover Proposal, or (iii) cause General Re to enter into any letter of intent, agreement in principle, acquisition agreement or other similar agreement related to any Takeover Proposal (a "Third Party Acquisition Agreement"). Notwithstanding the foregoing, the Board of Directors of General Re, to the extent that it determines in good faith, after consultation with outside counsel, that in light of a Superior Proposal it is necessary to do so in order to act in a manner consistent with its fiduciary duties to General Re's stockholders under applicable law, may terminate the Merger Agreement solely in order to concurrently enter into a Third Party Acquisition Agreement with respect to any Superior Proposal, but only at a time that is after the second business day following Berkshire's receipt of written notice advising Berkshire that the Board of Directors of General Re is prepared to accept a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the person making such Superior Proposal, all of which information will be kept confidential by Berkshire.

In addition to the obligations of General Re set forth above, General Re has agreed to immediately advise Berkshire orally and in writing of any request for information or any Takeover Proposal, the material terms and conditions of such request or Takeover Proposal and the identity of the person making such request or Takeover Proposal. General Re has further agreed to keep Berkshire reasonably informed of the status and details (including amendments or proposed amendments) of any such request or Takeover Proposal.

Nothing contained in the covenant not to solicit prohibits General Re from taking and disclosing to its stockholders a position contemplated by Rule 14e- 2(a) promulgated under the Exchange Act or from making any disclosure to General Re's stockholders if, in the good faith judgment of the Board of Directors of General Re, after consultation with outside counsel, failure so to disclose would be inconsistent with its obligations under applicable law; provided, however, that, neither General Re nor its Board of Directors nor any committee thereof may withdraw or modify, or propose publicly to withdraw or modify, its position with respect to the Merger Agreement or the Transactions or approve or recommend, or propose publicly to approve or recommend, a Takeover Proposal.

TERMINATION

The Merger Agreement may be terminated and abandoned at any time prior to the Effective Time, whether before or after approval of the Transactions by the stockholders of General Re and Berkshire:

(i) by mutual written consent of Berkshire and General Re;

(ii) by either party if (a) any Federal, state or local government or any court, administrative agency or commission or other governmental authority or agency, domestic or foreign, shall have issued an order, decree or ruling or taken any other action permanently enjoining, restraining or otherwise prohibiting one or both of the Mergers or the Transactions and such order, decree, ruling or other action shall have become final and nonappealable; (b) the Transactions shall not have been consummated on or before June 1, 1999 (other than due to the failure of the party seeking to terminate the Merger Agreement to perform its obligations thereunder); (c) any required approval of the stockholders of either party shall not have been obtained by reason of the failure to obtain the required vote upon a vote held at a duly held meeting of stockholders or at any adjournment thereof; or (d) if the other party fails to perform any of its material obligations under this Agreement and such failure has not been cured within thirty days after receipt of written notice of such failure;

(iii) by Berkshire, (a) if General Re (1) withdraws, modifies or amends in any respect adverse to Berkshire or New Berkshire its approval or recommendation of the Merger Agreement or the Transactions, (2) recommends any Takeover Proposal from a person other than Berkshire or (3) resolves to do any of the foregoing, or (b) if (1) General Re, in response to a Superior Proposal, furnishes information or participates in discussion as permitted by the Merger Agreement, and such discussions, directly or through agents or representatives, continue for more than 10 business days after the receipt of such Superior Proposal, or

53

(2) (x) a Takeover Proposal that is publicly disclosed shall have been commenced, publicly proposed or communicated to General Re which contains a proposal as to price (without regard to whether such proposal specifies a specific price or a range of potential prices) and (y) General Re shall not have rejected such proposal within 10 business days of its receipt or, if sooner, the date its existence first becomes publicly disclosed; or

(iv) by General Re, to concurrently enter into a Third Party Acquisition Agreement with respect to a Superior Proposal.

Upon termination, the Merger Agreement shall become void and have no effect, without any liability or obligation on the part of Berkshire or General Re, other than the payment of expenses as described in "The Transactions--Fees and Expenses" below, and the payment of the Termination Fee (as defined below). Termination does not relieve any party for any breach of the representations, warranties, covenants or agreements set forth in the Merger Agreement prior to any such termination.

TERMINATION FEE

If the Merger Agreement is terminated by General Re in order for General Re to concurrently enter into a Third Party Acquisition Agreement with respect to a Superior Proposal or if prior to any termination of the Merger Agreement, General Re or General Re's Board of Directors or any committee thereof shall have taken any action to make the General Re's Rights Agreement dated as of September 11, 1991 with Bank of New York, as right agent (the "Rights Plan"), inapplicable to any person other than Berkshire or New Berkshire, then, concurrently with any such termination or action, General Re is required to
(i) pay Berkshire a fee equal to $400 million and (ii) promptly reimburse Berkshire its out-of-pocket expenses related to the Merger Agreement and the Transactions.

If the Merger Agreement is terminated by Berkshire due to a reason set forth in paragraph (iii) under "The Transactions--Termination" above, or if a Takeover Proposal shall have been made to General Re or any of its subsidiaries or stockholders or any person shall have publicly announced an intention (whether or not conditional) to make a General Re Takeover Proposal and thereafter this Agreement is terminated by either party due to the failure to obtain the required stockholder vote of Berkshire or General Re and, in either case, within 18 months after the date of such termination General Re enters into any Third Party Acquisition Agreement relating to any Takeover Proposal, then General Re is required to (i) promptly (but in no event later than two business days after the date such agreement is entered into) pay Berkshire a fee equal to $400 million and (ii) reimburse Berkshire its out-of- pocket expenses related to the Merger Agreement and the Transactions.

The fee described in the preceding paragraphs is referred to herein as the "Termination Fee."

(vii) the absence of certain changes or events since the most recent audited financial statements filed with the Commission, including material adverse changes with respect to Berkshire; (viii) compliance with all applicable laws;
(ix) the inapplicability of any state takeover statute or similar statute or regulation of the State of Delaware (and, to the knowledge of Berkshire, of any other state or jurisdiction) to the Merger Agreement and the transactions contemplated thereby, the absence of any provision of Berkshire's Certificate of Incorporation, Bylaws or other governing instruments that would restrict or impair the ability of New Berkshire to exercise the rights of a stockholder with respect to securities of Berkshire and its subsidiaries or the rights granted under the Merger Agreement or permit any stockholder to acquire securities of Berkshire or its subsidiaries on a basis not available to New Berkshire; (x) the interim operations of New Berkshire and the Merger Subs;
(xi) brokers' fees and expenses; (xii) the Berkshire Board's recommendation and determinations with respect to the Merger Agreement and the transactions contemplated thereby, including the Transactions, the Berkshire Merger, and the Alternative General Re Merger; and (xiii) the required vote of Berkshire's stockholders necessary to approve the Merger Agreement, the Berkshire Merger and the other transactions contemplated thereby.

INDEMNIFICATION

The Merger Agreement provides that General Re will, and from and after the Effective Time, New Berkshire will, indemnify, defend, protect and hold harmless each person who is now, or has been at any time prior to the date of the Merger Agreement or who becomes such prior to the Effective Time, an officer or director of General Re or any of its subsidiaries (the "Indemnified Parties") against (i) all losses, claims, damages, costs, expenses, liabilities or judgments or amounts that are paid in settlement with the approval of the indemnifying party (which approval will not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding or investigation based in whole or in part on or arising in whole or in part out of the fact that such person is or was a director, officer or employee of General Re or any of its subsidiaries (the "Indemnified Parties"), whether pertaining to any matter existing or occurring at or prior to the Effective Time and whether

55

asserted or claimed prior to, or at or after, the Effective Time ("Indemnified Liabilities") and (ii) all Indemnified Liabilities based in whole or in part on, arising in whole or in part out of, or pertaining to the Merger Agreement, the Stock Option Agreement or the transactions contemplated thereby. In the case of General Re, such indemnification will only be to the fullest extent a corporation is permitted under the DGCL to indemnify its own directors and officers, and in the case New Berkshire, such indemnification will not be limited by the DGCL but will not be applicable to any claims made against the Indemnified Parties if a judgment or other final adjudication establishes that their acts or omissions (A) were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so deliberated or (B) arose out of, were based upon or attributable to the gaining of any financial profit or other advantage to which they were not legally entitled. General Re or New Berkshire, as the case may be, will pay all expenses of each Indemnified Party in advance of the final disposition of any such action or proceeding to the fullest extent permitted by law upon receipt of any undertaking contemplated by Section 145(e) of the DGCL.

FEES AND EXPENSES

Whether or not the Transactions are consummated, all costs and expenses incurred in connection with the Agreement and the transactions contemplated thereby will be paid by the party incurring such expenses, except that expenses in connection with the printing and mailing of this Joint Proxy Statement/Prospectus, the registration statement of which this is a part, and filing fees with the Commission, will be shared equally between Berkshire and General Re.

AMENDMENT AND WAIVER

The Merger Agreement may be amended by the parties at any time before or after required approval of the Transactions by the stockholders of General Re and of Berkshire; provided, however, that after such approvals, no amendment will be made that by law requires further stockholder approval unless such approval is obtained. Prior to the Effective Time, the parties may (i) extend the time for the performance of any obligation or other act of any other party to the Merger Agreement, (ii) waive any inaccuracies in the representations and warranties contained in the Merger Agreement or in any document delivered pursuant thereto or (iii) subject to any required stockholder approval, waive compliance with any of the agreements or conditions contained in the Merger Agreement.

UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

The following unaudited pro forma combined condensed financial statements are based on the historical consolidated financial statements of Berkshire and General Re, combined and adjusted to give effect to the Mergers. Certain reclassifications have been made to the historical financial statements to conform with this pro forma presentation. These statements should be read in conjunction with such historical financial statements and notes thereto, which are incorporated by reference in this Joint Proxy Statement/Prospectus. See "Where You Can Find More Information".

The unaudited pro forma combined condensed statements of earnings for the year ended December 31, 1997 and for the six months ended June 30, 1998 present the results for Berkshire and General Re as if the Mergers had occurred at the beginning of each period presented. The accompanying unaudited pro forma combined condensed balance sheet as of June 30, 1998 gives effect to the Mergers as of that date.

The pro forma adjustments are based upon preliminary estimates, information currently available and certain assumptions that management believes are reasonable under the circumstances. Berkshire's actual consolidated financial statements will reflect the effects of the Mergers on and after the Effective Time rather than the dates indicated above. The unaudited pro forma combined condensed financial statements neither purport to represent what the combined results of operations or financial condition actually would have been had the Mergers and related transactions in fact occurred on the assumed dates, nor to project the combined results of operations and financial position for any future period.

The Mergers will be accounted for by the purchase method and, therefore, assets and liabilities of General Re will be recorded at their fair values. The excess of the purchase cost over the fair value of net assets acquired at the Effective Time will be recorded as goodwill. Allocations included in the pro forma statements are based on analysis which is not yet completed. Accordingly, the final value of the purchase price and its allocation may differ, perhaps significantly, from the amounts included in these pro forma statements.

At the Effective Time, each issued and outstanding share of General Re Common Stock will be converted into the right to receive either 0.0035 Class A shares or 0.105 Class B shares of New Berkshire Common Stock. The pro forma combined condensed financial statements assume that all General Re shares were converted into Class A shares at the fixed exchange ratio of 0.0035. The total value of the consideration for pro forma purposes was determined using the average closing price of Berkshire Class A Common Stock on the NYSE for the ten day trading period ended June 26, 1998. The total consideration for the transaction using this value was $21.1 billion.

The pro forma financial statements were prepared under the expectation that the IRS issues certain rulings requested by the companies on the tax aspects of the transaction. See "The Transactions--Federal Income Tax Considerations of the Transactions". If the rulings are denied or not obtained prior to February 19, 1999, Berkshire has the right to elect to proceed with the Alternative Transaction, as described under "The Transactions--The Alternative Transaction." Under the Alternative Transaction, Berkshire would have paid cash of approximately $634 million for 3% of the total consideration and issued approximately 8,200 fewer Class A equivalent shares than reflected in the following pro forma financial statements. The Alternative Transaction scenario would not result in materially different pro forma combined results from operations or financial condition than the pro forma information presented herein.

NOTES TO THE UNAUDITED PRO FORMA COMBINEDCONDENSED FINANCIAL STATEMENTS

The pro forma adjustments to the combined condensed statements of earnings are described below.

(A) Reduction of interest income due to amortization of purchase accounting adjustments related to certain of General Re's investments in securities with fixed maturities.

(B) Estimation of (1) the increase in compensation expense related to the anticipated replacement of General Re's employee stock option plan with a new incentive compensation plan that would not require the issuance of stock options or securities of Berkshire and (2) the increase in compensation expense related to the use of non-dividend paying Berkshire stock with respect to the General Re Employee Savings and Stock Ownership Plan ("ESSOP").

(C) Amortization of the excess of purchase price over the fair value of net assets acquired, net of the elimination of goodwill amortization included in General Re's historical statement of earnings. The excess of purchase price over fair value of net assets recorded with respect to the merger will be amortized ratably over 40 years.

(D) Amortization of purchase accounting adjustments related to General Re's outstanding debt.

(E) Income tax effects on pro forma adjustments.

The purchase accounting and pro forma adjustments related to the combined condensed balance sheet are described below. Dollar amounts are in millions.

(F) Excess of purchase price over the fair value of net assets acquired ($13,947), less the elimination of goodwill included in General Re's historical balance sheet ($956).

(G) Recognition of liabilities related to the estimated value of General Re employee stock options ($635) and estimated General Re and Berkshire merger costs ($74).

(H) Conversion of General Re's redeemable cumulative convertible preferred stock into Berkshire common stock ($144) and adjustment of related ESSOP loan balances to fair value ($40).

(I) Adjustment of income tax liabilities applicable to pro forma adjustments, other than goodwill, estimated merger costs and General Re Preferred stock.

(J) Adjustment of General Re's consolidated debt to fair value.

(K) Issuance of 270,710 Class A equivalent New Berkshire shares in exchange for General Re shares ($21,126), less elimination of General Re's historical shareholders' equity accounts ($8,479).

Warren E. Buffett and Susan T. Buffett are husband and wife. Howard G. Buffett is the son of Warren and Susan Buffett. Otherwise, there is no family relationship between any other officer or director of the Corporation.

Ronald L. Olson is a partner of the law firm of Munger, Tolles & Olson LLP, which rendered legal services to Berkshire and its subsidiaries in 1997 and is expected to render legal services to New Berkshire in 1998. In January 1998, Mr. Olson and his wife agreed to sell a home owned by them to MS Property Company, a subsidiary of Wesco Financial Corporation, which is an 80.1% owned subsidiary of Berkshire, and to purchase another home from MS Property Company. Both homes are located in a community developed by MS Property Company. The values of the homes and terms of the exchange were determined by Mr. Munger, approved by Wesco Financial Corporation's board of directors and accepted by Mr. Olson.

COMPENSATION OF DIRECTORS AND COMMITTEES OF THE BOARD OF DIRECTORS

Mr. Scott is expected to be the member of the audit committee of the New Berkshire Board. The functions of the audit committee are to select the independent auditors; review the results of the annual audit; inquire into important internal control, accounting and financial reporting matters; and report and make recommendations to the full Board of Directors. New Berkshire will not have standing nominating or compensation committees of the Board of Directors.

Directors who are employees of New Berkshire or its subsidiaries will not receive fees for attendance at directors' meetings. Directors who are not employees will receive a fee of $900 for each meeting attended in person and $300 for participating in any meeting conducted by telephone. A director who serves as a member of the audit committee will receive additional fees of $1,000 quarterly. Directors will be reimbursed for their out-of-pocket expenses incurred in attending meetings of directors or shareholders.

EXECUTIVE OFFICERS

Set forth below are the names and titles of certain of the persons who are expected to serve as executive officers of New Berkshire (or, in the event of the Alternative Transaction, of Berkshire) following the Transactions.

     NAME                               AGE  POSITION WITH REGISTRANT  SINCE
     ----                               ---  ------------------------  -----
Warren E. Buffett......................  67 Chairman of the Board      1970
Marc D. Hamburg........................  49 Vice President             1992
Charles T. Munger......................  74 Vice Chairman of the Board 1978

Each executive officer will serve, in accordance with the bylaws of New Berkshire, until the first meeting of the Board of Directors following the next annual meeting of shareholders and until his respective successor is chosen and qualified or until he sooner dies, resigns, is removed or becomes disqualified. Mr. Buffett and Mr. Munger will also serve as directors of New Berkshire.

65

COMPENSATION OF EXECUTIVE OFFICERS

New Berkshire has not yet paid any compensation to any of its executive officers, and the form and amount of such compensation has not yet been determined. However, New Berkshire is expected to continue Berkshire's program, which has been different from that of most public corporations. Mr. Buffett recommends to the Berkshire Board of Directors the amount of his proposed remuneration and he sets the remuneration of Berkshire's other executive officers (including both salary and bonus). Mr. Buffett has been paid an annual salary of $100,000 for each of the last 17 years. Factors considered by the Board of Directors and Mr. Buffett are typically subjective, such as their perception of the individual's performance and any planned change in functional responsibility. Neither the profitability of Berkshire nor the market value of its stock are considered in setting executive officer remuneration (including both salary and bonus). Further, it is Berkshire's policy that all compensation paid to its executive officers be deductible under Internal Revenue Code Section 162(m).

For information concerning the compensation paid to the Chief Executive Officers and certain other executive officers of each of Berkshire and General Re for the 1997 fiscal year, see the 1998 Proxy Statements for Berkshire and General Re, the relevant portions of which are incorporated by reference into the Berkshire's and General Re's Annual Report on Form 10-K for the Year Ended December 31, 1997, respectively.

(1) Beneficial owners exercise both sole voting and sole investment power unless otherwise stated. New Berkshire Class A Common Stock is convertible into thirty shares of New Berkshire Class B Common Stock at the option of the stockholder. As a result, pursuant to Rule 13d-3(d)(1) of the Exchange Act, a stockholder will be deemed to have beneficial ownership of the shares of New Berkshire Class B Common Stock which such stockholder may acquire upon conversion of the New Berkshire Class A Common Stock. In order to avoid overstatement, the amount of New Berkshire Class B Common Stock beneficially owned does not take into account such shares of New Berkshire Class B Common Stock which may be acquired upon conversion (an amount which is equal to 30 times the number of shares of New Berkshire Class A Common Stock held by a stockholder).

(1) Beneficial owners exercise both sole voting and sole investment power unless otherwise stated. Berkshire Class A Common Stock is convertible into thirty shares of Berkshire Class B Common Stock at the option of the stockholder. As a result, pursuant to Rule 13d-3(d)(1) of the Exchange Act, a stockholder is deemed to have beneficial ownership of the shares of New Berkshire Class B Common Stock which such stockholder may acquire upon conversion of the Berkshire Class A Common Stock. In order to avoid overstatement, the amount of Berkshire Class B Common Stock beneficially owned does not take into account such shares of Berkshire Class B Common Stock which may be acquired upon conversion (an amount which is equal to 30 times the number of shares of Berkshire Class A Common Stock held by a stockholder). The percentage of outstanding Berkshire Class B Common Stock is based on the total number of shares of Berkshire Class B Common Stock outstanding as of the Record Date (1,747,632 shares) and does not take into account shares of Berkshire Class B Common Stock which may be issued upon conversion of Berkshire Class A Common Stock.

(2) Includes 474,998 shares owned directly and beneficially by Warren E. Buffett, and 3,234 shares owned by three trusts of which Mr. Buffett is sole trustee but with respect to which Mr. Buffett disclaims any beneficial economic interest. Mr. Buffett shares investment and voting power with respect to 36,981 shares of Berkshire Class A Common Stock and 6 Class B Common Stock owned by Susan T. Buffett.

69

(3) Mr. and Mrs. Buffett have entered into a voting agreement with Berkshire providing that, should the combined voting power of shares held by Mr. and Mrs. Buffett and the trusts exceed 49.9% of Berkshire's total voting power, they will vote those shares in excess of that percentage proportionately with votes of the other Berkshire shareholders.

(4) Includes 448 shares of Berkshire Class A Common Stock for which Mr. Chace has sole investment and voting power. Also includes 12,400 shares of Berkshire Class A and 62 shares of Berkshire Class B Common Stock held by various trusts of which Mr. Chace is a trustee and 160 shares of Berkshire Class A shares held by an estate for which Mr. Chace is an executor and for which he has shared investment and voting power. Excluded are 987 shares of Berkshire Class A Common Stock in which Mr. Chace has a pecuniary interest but with respect to which he possesses neither investment power nor voting power, and also does not include 54 Shares of Berkshire Class A Common Stock owned by Elizabeth Z. Chace, wife of Mr. Chace.

(5) Does not include 10 shares of Berkshire Class A Common Stock owned by Suzanne M. Scott, wife of Walter Scott, Jr.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF GENERAL RE

At the Record Date the only person known by General Re management to be a beneficial holder, directly or indirectly, of more than 5% of General Re Common Stock is Capital Research and Management Company, 333 South Hope Street, Los Angeles, California 90071, which reported in a Schedule 13G dated July 9, 1998 that it beneficially owned 4,605,300 shares of General Re Common Stock (6.1% as of the Record Date), with respect to which it had sole voting power over no shares and sole dispositive power over 4,605,300 shares, and no shared voting or dispositive power. All of the outstanding shares of General Re Preferred Stock are held by the ESSOP.

The following table shows the number of shares of General Re Common Stock beneficially owned as of the Record Date by each director and by the Chief Executive Officer and the four most highly compensated executive officers of General Re (including the beneficial ownership of General Re Preferred Stock held by the ESSOP, which is reported as shares of General Re Common Stock because the General Re Preferred Stock is convertible into and votes with General Re Common Stock as a class). Except as otherwise indicated, each person has sole voting and investment power with respect to the shares shown.

(1) Includes shares of General Re Common Stock held in the names of spouses and children, as to which beneficial ownership is disclaimed. No person named above beneficially owns more than 1% of the outstanding stock. Does not include the following shares underlying stock options exercisable within 60 days: Ronald E. Ferguson: 62,989 shares; James E. Gustafson:
35,583 shares; Tom N. Kellogg: 41,406 shares; Peter Lutke-Bornefeld:
18,000 shares; Peter A. Minton: 3,340 shares; and all executive officers as of July 10, 1998 as a group: 338,655 shares.

(2) Non-employee directors may elect to defer all or part of their compensation to be held in deferral accounts either in cash or as units equivalent to shares of General Re Common Stock ("share units"). Executive officers may receive a portion of their bonuses in share units and may receive, in appropriate circumstances, share units subject to certain restrictions ("restricted share units"). Share units and restricted share units carry no voting rights. Also, executive officers receive awards of share units under the Supplemental Benefit Equalization Plan (the "SBEP") to the extent that shares of General Re Preferred Stock cannot be allocated to an executive officer under the terms of the ESSOP because of limits imposed by the Code. In addition,

71

Peter Lutke-Bornefeld holds 13,367 restricted share units: 5,225 will convert to unrestricted shares of General Re Common Stock on January 3, 2000; and 8,142 will convert to unrestricted shares of General Re Common Stock on April 8, 2006.

(3) Shares of General Re Preferred Stock are allocated to the accounts of participants in the ESSOP pursuant to the terms of the ESSOP. Distributions under the ESSOP are made in cash or shares of General Re Common Stock into which the General Re Preferred Stock is convertible. The participants in the ESSOP have the right to instruct the trustee with respect to the vote of the shares allocated to their accounts and a portion of the General Re Preferred Stock that has not been allocated to any participant's account or for which no instructions are timely received by the trustee, whether or not allocated to the account of any participant. The number of shares of General Re Common Stock disclosed above includes the shares of General Re Preferred Stock allocated to each participant's account but excuses any unallocated shares because of the trustee's fiduciary duty relating to the voting of unallocated shares under the Employee Retirement Income Security Act of 1974. The number of shares allocated to the accounts of the persons named above, if any, and the minimum number of unallocated shares as to which they may give voting instructions are as follows: Ronald E. Ferguson: 833 allocated shares, 2,217 unallocated shares; James E. Gustafson: 821 allocated shares, 2,185 unallocated shares; Tom N. Kellogg: 1,216 allocated shares, 3,236 unallocated shares; Peter A. Minton: 8 allocated shares, 22 unallocated shares; and all executive officers as of the Record Date as a group: 11,414 allocated shares and 30,378 unallocated shares.

(4) Includes stock that is subject to restrictions on resale. Ronald E. Ferguson holds 15,000 restricted shares (15,000 restricted until January 2002); James E. Gustafson holds 18,000 restricted shares (2,500 restricted until September 1999, 2,500 restricted until November 2001, 13,000 restricted until October 2006); Tom N. Kellogg holds 5,000 restricted shares (5,000 restricted until February 2000); Peter A. Minton holds 2,000 restricted shares (500 restricted until February 2003, 500 restricted until February 2005, 1,000 restricted until July 2018); and all executive officers as of the Record Date as a group hold 92,700 restricted shares.

THE BERKSHIRE CHARTER AMENDMENT

Article Fourth of the Berkshire Restated Certificate of Incorporation (the "Berkshire Certificate") as currently in effect authorizes the issuance of up to an aggregate of 51,500,000 shares of Berkshire Common Stock, of which 1,500,000 are shares of Class A Common Stock and 50,000,000 are shares of Class B Common Stock. As of the Record Date, 1,188,054 shares of Class A Common Stock and 1,747,632 shares of Class B Common Stock were issued and outstanding and 35,669,120 shares of Class B Common Stock were reserved for issuance upon conversion of Class A Common Stock and outstanding stock options. There were, therefore 311,946 shares of Class A and 14,330,880 shares of Class B Common Stock available for future issuances.

If the Transactions are approved by Berkshire and General Re stockholders, and Berkshire elects the Alternative Transaction, up to approximately 262,620 shares of Class A equivalents (assuming all General Re stockholders make the Class A Election ) will be subject to issuance to holders of General Re Common Stock and approximately 575,000 shares of Class B Common Stock will be subject to options, and 49,326 shares of Class A Common Stock and 5,878,180 shares of Class B Common Stock would be available for future issuances.

The Berkshire Board believes it would be desirable to increase the number of shares of authorized Berkshire Common Stock in order to make available additional shares for possible acquisitions or other purposes. After giving effect to the Berkshire Charter Amendment, the amount of authorized Berkshire Common Stock will be the same as that currently authorized for New Berkshire. If Berkshire stockholders approve the Berkshire Charter Amendment, it will be filed with the Delaware Secretary of State and become effective only in the event Berkshire makes the Alternative Election.

All newly authorized shares of Berkshire Common Stock would have the same rights as the presently authorized shares. Under the Berkshire Certificate, stockholders of Berkshire do not have preemptive rights.

73

BUSINESS RELATIONSHIPS BETWEEN BERKSHIRE AND GENERAL RE

For many years, certain of Berkshire's property and casualty insurance subsidiaries have entered into reinsurance contracts with General Re. Within the contracts, Berkshire either assumed risks from or ceded risks to General Re. In most cases, these contracts provided that Berkshire serve as the assuming enterprise and General Re serve as the ceding enterprise. In recent years, these contracts provided principally excess of loss reinsurance coverage. Excess of loss reinsurance refers to an arrangement in which the assuming company indemnifies the ceding company, subject to specified limitations, for all or a portion of a loss amount in excess of a stipulated retention by the ceding company.

DESCRIPTION OF NEW BERKSHIRE CAPITAL STOCK

The authorized capital stock of New Berkshire consists of 1,650,000 shares of New Berkshire Class A Common Stock, 55,000,000 shares of New Berkshire Class B Common Stock and 1,000,000 shares of preferred stock, no par value per share ("Berkshire Preferred Stock").

The following summary of certain provisions of the New Berkshire Class A Stock, Berkshire Class B Common Stock and New Berkshire Preferred Common Stock does not purport to be complete and is subject to, and qualified in its entirety by, the provisions of applicable law and New Berkshire's Certificate of Incorporation.

The holders of outstanding shares of New Berkshire Class A Common Stock are entitled to one vote, and the holders of outstanding shares of New Berkshire Class B Common Stock are entitled to one two-hundredth ( 1/200th) of a vote, for each share held of record on all matters submitted to a vote of stockholders. Unless otherwise required by the DGCL, the New Berkshire Class A Common Stock and New Berkshire Class B Common Stock vote as a single class with respect to all matters submitted to a vote of stockholders of Berkshire.

Mr. Buffett will own approximately 32.8% of the New Berkshire Class A Stock, (based on the assumptions stated in note (2) to the table under "Security Ownership of Certain Beneficial Owners and Management of New Berkshire"). He will share voting and investment power over another 2.5% of such stock, which will be owned by his wife, Susan T. Buffett, and 0.2% of such stock, which will be owned by trusts of which he is trustee but in which he has no economic interest. Mr. and Mrs. Buffett have entered into a voting agreement with Berkshire, which will be applicable to the shares of New Berkshire beneficially owned by Mr. and Mrs. Buffett, providing that, should the voting power of shares held by Mr. and Mrs. Buffett and the trust exceed 49.9% of the total voting power of Berkshire (and therefore New Berkshire) voting securities, they will vote their shares in excess of that percentage proportionally with the votes of the other stockholders.

Each share of New Berkshire Class A Common Stock may be converted into thirty (30) shares of New Berkshire Class B Common Stock at the holder's option at any time. Shares of New Berkshire Class B Common Stock are not convertible into New Berkshire Class A Common Stock or any other security.

Holders of New Berkshire Class A Stock are entitled to receive ratably such dividends as may be declared by the New Berkshire Board out of funds legally available therefor. Holders of New Berkshire Class B Common Stock will be entitled to dividends equal to one-thirtieth ( 1/30th) of the amount per share declared by New Berkshire's Board for each share of New Berkshire Class A Common Stock. Dividends with respect to the New Berkshire Class B Common Stock will be paid in the same form and at the same time as dividends with respect to New Berkshire Class A Common Stock, except that, in the event of a stock split or stock dividend, holders of New Berkshire Class A Common Stock will receive shares of New Berkshire Class A Common Stock and holders of New Berkshire Class B Common Stock will receive shares of New Berkshire Class B Stock, unless otherwise specifically designated by resolution of the New Berkshire Board. New Berkshire will continue Berkshire's dividend policy. Berkshire has not declared a cash dividend since 1967 and has no present intention to pay a dividend on Berkshire Class A Common Stock or on Berkshire Class B Common Stock in the future.

74

In the event of the liquidation, dissolution or winding-up of New Berkshire, holders of New Berkshire Class A Common Stock and New Berkshire Class B Common Stock are entitled to share ratably in all assets remaining after the payment of liabilities, with holders of New Berkshire Class B Common Stock entitled to receive per share one-thirtieth ( 1/30th) of any amount per share received by holders of New Berkshire Class A Common Stock. Neither holders of New Berkshire Class A Common Stock nor New Berkshire Class B Stock shall have preemptive rights to subscribe for additional shares of either class. All shares of New Berkshire Class A Common Stock and New Berkshire Class B Common Stock outstanding upon completion of the Transaction will be fully paid and nonassessable.

No shares of New Berkshire Preferred Stock are presently outstanding. In the future, New Berkshire may issue the New Berkshire Preferred Stock in one or more series. The New Berkshire Board is authorized to determine, with respect to each series of New Berkshire Preferred Stock which may be issued, the powers, designations, preferences, and rights of the shares of such series and the qualifications, limitations, or restrictions thereof, including any dividend rate, redemption rights, liquidation preferences, sinking fund terms, conversion rights, voting rights and any other preferences or special rights and qualifications. The effect of any issuance of the New Berkshire Preferred Stock upon the rights of holders of the New Berkshire Class A Common Stock and New Berkshire Class B Common Stock depends upon the respective powers, designations, preferences, rights, qualifications, limitations and restrictions of the shares of one or more series of New Berkshire Preferred Stock as determined by the New Berkshire Board. Such effects might include dilution of the voting power of the New Berkshire Class A Common Stock and New Berkshire Class B Common Stock, the subordination of the rights of holders of New Berkshire Class A Common Stock and New Berkshire Class B Common Stock to share in New Berkshire's assets upon liquidation, and a reduction in the amount otherwise available for payment of dividends on New Berkshire Class A Common Stock and New Berkshire Class B Common Stock.

75

COMPARISON OF RIGHTS OF STOCKHOLDERS

At the Effective Time, the stockholders of Berkshire and General Re will become stockholders of New Berkshire. As stockholders of New Berkshire, their rights will be governed by the DGCL and New Berkshire's Certificate of Incorporation (the "New Berkshire Certificate") and Bylaws (the "New Berkshire Bylaws"). Following are summaries of certain differences between (i) the rights of Berkshire stockholders and New Berkshire stockholders and (ii) the rights of General Re stockholders and New Berkshire stockholders. The summaries do not purport to be complete and are qualified in their entirety by reference to the New Berkshire Certificate and Bylaws, the Berkshire Certificate of Incorporation and Bylaws and the General Re Restated Certificate of Incorporation (the "General Re Certificate") and General Re Bylaws, as applicable.

New Berkshire, Berkshire and General Re are each organized under the laws of the State of Delaware. Any differences, therefore, in the rights of holders of New Berkshire Common Stock, on the one hand, and Berkshire Common Stock and General Re Common Stock, respectively, on the other hand, arise solely from differences in their respective certificates of incorporation and bylaws.

COMPARISON OF STOCKHOLDERS' RIGHTS WITH RESPECT TO NEW BERKSHIRE AND BERKSHIRE

The New Berkshire Certificate of Incorporation and the New Berkshire Bylaws are substantially similar to the Berkshire Certificate of Incorporation and the Berkshire Bylaws, respectively, except as described below.

Authorized Capital. The total number of authorized shares of capital stock of Berkshire is 52,500,000 shares, consisting of 1,500,000 shares of Berkshire Class A Common Stock, 50,000,000 shares of Berkshire Class B Common Stock and 1,000,000 shares of preferred stock. The authorized capital of New Berkshire is 57,650,000 shares, consisting of 1,650,000 shares of New Berkshire Class A Common Stock, 55,000,000 shares of New Berkshire Class B Common Stock and 1,000,000 shares of preferred stock.

COMPARISON OF STOCKHOLDERS' RIGHTS WITH RESPECT TO NEW BERKSHIRE AND GENERAL RE

Number of Directors. Under the DGCL, the certificate of incorporation or bylaws of a corporation may specify the number of directors. The New Berkshire Bylaws provide that the New Berkshire Board will determine the number of Berkshire directors. The General Re Bylaws provide that the number of directors shall be not less than nine (9) nor more than twenty-one (21), as determined by a resolution of a majority of the directors of the General Re Board then in office or by the holders of 60% in interest of the outstanding voting shares of General Re, including the holders of 60% in interest of the outstanding voting shares of General Re held by persons other than an "interested stockholder" (as defined in the General Re Bylaws).

Removal of Directors. Under the New Berkshire Bylaws, holders of a majority of shares issued and outstanding and entitled to vote in the election of directors may remove a director with or without cause. Under the General Re Certificate and the General Re Bylaws, a director may only be removed for cause.

Vacancies in the Board of Directors. Under the New Berkshire Bylaws, a vacancy on the New Berkshire Board may be filled by a vote of the stockholders at a meeting called for that purpose, or by a majority of directors then in office, even though less than a quorum, or by a sole remaining director. Under the General Re Bylaws, a vacancy on the General Re Board may be filled by a majority of directors then in office, even though less than a quorum.

Annual Stockholder Meetings. The General Re Bylaws provide for an annual meeting of stockholders to be held at any time designated by the Board of Directors. The New Berkshire By-laws provide for an annual meeting to be held generally on the first Monday in May.

Special Stockholder Meetings. The New Berkshire Bylaws provide that a special meeting of stockholders may be called at any time by the Chairman of the Board of the New Berkshire Board. A special meeting may

76

also be called by New Berkshire's Secretary, or in the case of his death, absence, incapacity or refusal, by an assistant secretary or other officer, upon application of a majority of directors or stockholders who hold at least 50% of Berkshire's issued and outstanding capital stock. Under the General Re Certificate and the General Re By-laws, only the Board of Directors may call a special meeting of common stockholders.

Action by Written Consent. The General Re Certificate prohibits action by written consent except for action that may be taken solely upon the vote or consent in writing of holders of any series of preferred stock of General Re. The New Berkshire Certificate permits action by the written consent of stockholders who would be entitled to vote upon such action if such meeting were held having not less than the percentage of the total number of votes which would have been required to take such action at such a meeting.

Provisions Affecting Business Combinations. The General Re Certificate requires that any "business combination" (as defined in the General Re Certificate) with an "interested stockholder" shall require the affirmative vote of the holders of 60% in interest of the outstanding voting shares of General Re unless certain specified conditions are satisfied. This provision shall not apply if such "business combination" (i) has been approved prior to consummation by two-thirds of the "continuing directors" (as defined in the General Re Certificate) of General Re, or (ii) constitutes a merger or consolidation with any corporation of which a majority of the outstanding voting shares is owned of record by General Re (unless any affiliate of an "interested stockholder" is a party to such "business combination"). The New Berkshire Certificate specifies that any director individually, or any firm of which such director may be a member, may be a party to or have a pecuniary interest in any contract or transaction of the New Berkshire, provided that such fact or interest shall have been known to the New Berkshire Board, or a majority thereof, at the meeting at which the New Berkshire Board authorized such contract or transaction.

Stockholder Rights Plan. General Re has entered into the Rights Plan pursuant to which each share of General Re Common Stock is issued a General Re Stockholder Right. Berkshire does not have a stockholder rights plan.

The consolidated financial statements and schedules of General Re and its subsidiaries as of December 31, 1997 and 1996, and for each of the years in the three-year period ended December 31, 1997, included in the 1997 General Re Annual Report and Form 10-K, have been incorporated by reference herein, in reliance upon the reports (also incorporated by reference herein) of PricewaterhouseCoopers LLP, independent certified public accountants, and upon the authority of said firm as experts in accounting and auditing.

LEGAL MATTERS

Certain legal matters with respect to the validity of the New Berkshire (or Berkshire) Common Stock to be issued pursuant to the Mergers and certain federal income tax consequences of the Transactions will be passed upon by Munger, Tolles & Olson LLP for Berkshire. Ronald L. Olson, a partner of Munger, Tolles & Olson LLP, is a director of Berkshire and will be a director of New Berkshire. He and other attorneys in such firm beneficially own an aggregate of less than 1% of the outstanding Berkshire Common Stock. Certain legal matters with respect to certain federal income tax consequences of the Transactions will be passed upon by Wachtell, Rosen, Lipton & Katz for General Re and, in the event of the Alternative Transaction, for Berkshire.

SUBMISSION OF FUTURE STOCKHOLDER PROPOSALS

Stockholder proposals intended to be presented at the 1999 Annual Meeting of Stockholders of New Berkshire must be received by the Secretary of New Berkshire not later than November 18, 1998 for inclusion in the proxy materials for such meeting. The proposal must be in accordance with the provisions of Rule 4a-8 promulgated by the Commission under the Exchange Act. It is suggested the proposal be submitted by certified mail, return receipt requested.

Due to the contemplated consummation of the General Re Merger, General Re does not currently expect to hold a 1999 Annual Meeting of Stockholders because General Re will be a wholly owned subsidiary of Berkshire or New Berkshire. In the event that the General Re Merger is not consummated and such a meeting is held, to be eligible for inclusion in General Re's proxy statement and form of proxy relating to that meeting, proposals of stockholders intended to be presented at such meeting must be received by General Re either (i) within a reasonable time after General Re announces publicly the date of the meeting and before General Re mails its proxy statement to stockholders in connection with such meeting, or (ii) no later than December 1, 1998, if General Re shall have announced publicly its intention not to consummate the General Re Merger prior to such date.

Holding Company shall assume all rights and obligations of Berkshire under Berkshire's stock option plans as in effect at the Effective Time and shall continue such plans in accordance with their terms.

(i) Adjust the terms of all outstanding employee stock options to purchase shares of General Common Stock ("General Stock Options") granted under any of General's 1995 Long Term Compensation Plan, Long Term Compensation Plan, 1996 Employee Stock Award Plan or 1989 Long Term Compensation Plan (collectively, the "Option Plans"), to provide that, at the Effective Time, each General Stock Option outstanding immediately prior to the Effective Time shall (except to the extent that Berkshire and the holder of a General Stock Option otherwise agree in writing prior to the Effective Time) be deemed to constitute an option to acquire, on the same terms and conditions as were applicable under such General Stock Option, the number of shares of Holding Company Class B Common Stock equal to the product of (1) the number of shares of General Common Stock issuable upon exercise of such General Stock Option and (2) 0.105, provided that any fractional shares of Holding Company Class B Stock resulting from such multiplication shall be rounded up or down to the nearest one one-hundredth of a share (provided that, notwithstanding

Annex I-9


the foregoing, the terms of such General Stock Option shall provide for the payment of cash in lieu of any fractional share of Holding Company Class B Common Stock upon exercise thereof in an amount equal to such fraction multiplied by the last sale price of Holding Company Class B Common Stock as reported on the New York Stock Exchange ("NYSE") Composite Tape on the date of exercise), at a price per share equal to (x) the exercise price for the shares of General Common Stock otherwise purchasable pursuant to such General Stock Option divided by (y) 0.105, provided, that such exercise price shall be rounded up or down to the nearest cent.

3.5 Exchange of General Certificates.

(a) Exchange Agent. Prior to the mailing of the Proxy Statement/Prospectus to General's stockholders and Berkshire's stockholders, Berkshire shall designate and appoint a bank or trust company reasonably satisfactory to General to act as exchange agent (the "Exchange Agent") for the payment of the Merger Consideration. As soon as reasonably practicable as of or after the Effective Time, Holding Company shall deposit the Merger Consideration with the Exchange Agent for the benefit of the holders of shares of General Stock, for exchange in accordance with this Article 3.

(b) Exchange Procedures. As soon as practicable after the Effective Time, the Exchange Agent shall mail to each holder of an outstanding certificate or certificates which prior thereto represented shares of General Common Stock
(i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to such certificate shall pass, only upon delivery of such certificates to such Exchange Agent), and (ii) instructions for use in effecting the surrender of the certificates for the Merger Consideration. The letter of transmittal shall permit each such holder to elect (a "Class A Election") the aggregate number of shares of General Common Stock represented by the certificate(s) surrendered therewith to be converted into shares of Holding Company Class A Common Stock pursuant to Section 3.4(b)(i) or Section 3.7(c)(i), as the case may be, and shall provide that all shares of General Common Stock represented thereby with respect to which a Class A Election has not been made shall be converted into Holding Company Class B Common Stock pursuant to Section 3.4(b)(ii) or Section 3.7(c)(ii), as the case may be. Upon proper surrender to the Exchange Agent of such certificates for cancellation, the holder of such certificates shall after the Effective Time be entitled only to a certificate or certificates representing the number of full shares of Holding Company Common Stock into which the aggregate number of shares of General Common Stock previously represented by such certificate or certificates surrendered shall have been converted pursuant to this Agreement and any cash constituting Merger Consideration, cash in lieu of fractional shares and cash dividends or distributions to which such holder is entitled. The Exchange Agent shall accept such certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. After the Effective Time, there shall be no further transfer on the records of General or its transfer agent of certificates representing shares of General Common Stock and if such certificates are presented to General for transfer, they shall be cancelled against delivery of certificates for Holding Company Common Stock and cash in lieu of fractional shares as provided herein. If any certificate for such Holding Company Common Stock is to be issued in, or if cash is to be remitted to, a name other than that in which the certificate for General Common Stock surrendered for exchange is registered, it shall be a condition of such exchange that the certificate so surrendered shall be properly endorsed, with signature guaranteed, or otherwise in proper form for transfer and that the person requesting such exchange shall pay to Holding Company or its transfer agent any transfer or other taxes required by reason of the issuance of certificates for such Holding Company Common

Annex I-10


Stock in a name other than that of the registered holder of the certificate surrendered, or establish to the satisfaction of Holding Company or its transfer agent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 3.5(b), each certificate for shares of General Common Stock shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration and any cash payable hereunder. No interest will be paid or will accrue on the Merger Consideration, any dividends or distributions or any cash payable in lieu of any fractional shares of Holding Company Common Stock.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Holding Company Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered certificate for shares of General Common Stock with respect to the shares of Holding Company Common Stock represented thereby and no cash payment as Merger Consideration, for dividends or distributions on Holding Company Stock with a record date on or following the Effective Time or in lieu of fractional shares shall be paid to any such holder pursuant to Section 3.5(e) until the surrender of such certificate in accordance with this Section 3.5. Subject to the effect of applicable laws, following surrender of any such certificate, there shall be paid to the holder of the certificate representing whole shares of Holding Company Common Stock issued in exchange therefor, without interest,
(i) at the time of such surrender the amount of any cash payable in lieu of a fractional share of Holding Company Class B Common Stock to which such holder is entitled hereunder and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Holding Company Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Holding Company Common Stock.

(d) No Further Ownership Rights in General Common Stock. All shares of Holding Company Common Stock issued and cash paid pursuant to Section 3.5(e) upon the surrender for exchange of certificates representing shares of General Common Stock in accordance with the terms of this Article 3 shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of General Common Stock (and the associated Rights) theretofore represented by such certificates.

(e) No Fractional Shares. Each holder of shares of General Common Stock exchanged pursuant to the General Merger who would have otherwise been entitled to receive a fraction of a share of Holding Company Class A Common Stock shall receive, in lieu thereof, such number of shares of Holding Company Class B Common Stock in the amount of such fraction multiplied by 30. No certificates or scrip representing fractional shares of Holding Company Class B Common Stock shall be issued upon the surrender for exchange of certificates representing shares of General Common Stock, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a stockholder of Holding Company. Notwithstanding any other provision of this Agreement, (A) each holder of shares of General Common Stock exchanged pursuant to the General Merger who would have otherwise been entitled to receive a fraction of a share of Holding Company Class B Common Stock shall receive, in lieu thereof, a cash payment (without interest) equal to the product of (x) such fraction and (y) the Average Trading Price for one share of Berkshire Class B Common Stock. For purposes of this Agreement, "Average Trading Price" shall mean the average of the high and low trading prices of Berkshire Class A Common Stock or Bentwood Class B Common Stock, as the case may be, as reported on the NYSE Composite Tape for each of the five consecutive trading days ending on the last full trading day immediately prior to the date on which the Effective Time occurs.

(f) Termination of Exchange Fund. Any portion of the Merger Consideration deposited with the Exchange Agent pursuant to this Section 3.5 (the "Exchange Fund") which remains undistributed to the holders of the certificates representing shares of General Common Stock for nine months after the Effective Time shall be delivered to Holding Company, upon demand, and any holders of shares of General Common Stock who have not theretofore complied with this Article 3 shall thereafter look only to Holding Company and only as general creditors thereof for payment of their claim for Merger Consideration, any cash in lieu of fractional shares of

Annex I-11


Holding Company Class B Common Stock and any dividends or distributions with respect to whole shares of Holding Company Common Stock to which such holders may be entitled.

(g) No Liability. None of Holding Company, Berkshire, General or the Exchange Agent shall be liable to any person in respect of any shares of Holding Company Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any certificates representing shares of General Common Stock shall not have been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which any shares of Holding Company Common Stock, any cash payable as Merger Consideration or in lieu of fractional shares of Holding Company Class B Common Stock or any dividends or distributions with respect to Holding Company Common Stock in respect of such certificate would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 4.1(d)), any such shares, cash, dividends or distributions in respect of such certificate shall, to the extent permitted by applicable law, become the property of Holding Company, free and clear of all claims or interest of any person previously entitled thereto.

(h) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Berkshire (or Holding Company after the Effective Time), on a daily basis. Any interest and other income resulting from such investments shall be paid to Berkshire (or Holding Company after the Effective Time).

3.6 General Preferred Stock. General agrees to take all actions necessary to call for redemption, and to redeem, all of the shares of General Preferred Stock as of immediately prior to the Effective Time pursuant to the terms thereof.

3.7 Partial Cash Election.

(a) Subject only to Berkshire's compliance in all material respects with
Section 6.14, Berkshire shall be permitted to elect (the "Partial Cash Election"), but may decline to elect, to pay a portion of the Merger Consideration in cash as provided under Section 3.7(c). Berkshire may make the Partial Cash Election by giving written notice to General indicating that it is making the Partial Cash Election within ten business days following the earlier of (x) Berkshire being informed by the Internal Revenue Service of the United States ("IRS") that it will not grant the 351(e) Ruling (as defined in
Section 6.14) (and, if the IRS will not grant the 351(e) Ruling as a result of the United States Treasury Department (the "Treasury Department") withdrawing or announcing its intention to withdraw Proposed Treasury Regulation Sections 1.351-1(c)(1)(ii)(d) and 1.368-4 (the "Proposed Regulations"), Berkshire also being informed by the IRS that it will not grant the 368(c) Ruling (as defined in Section 6.14)), or (y) February 19, 1999. Notwithstanding the prior sentence, Berkshire may not make the Partial Cash Election if Berkshire has received written notice of the issuance of either (I) the 351(e) Ruling and the No Gain or Loss Ruling or (II), if the Treasury Department has withdrawn the Proposed Regulations, the No Gain or Loss Ruling or the 368(c) Ruling by the IRS on or prior to the date Berkshire makes the election. In the event Berkshire is entitled to make the Partial Cash Election and does not give any written notice declining to make the Partial Cash Election to General, as of the expiration of such ten business days, Berkshire shall be deemed to have made the Partial Cash Election. Berkshire shall not be permitted to make the Partial Cash Election except to the extent provided in this Section 3.7. Notwithstanding any provision to the contrary contained in this Agreement, none of the failure to receive one or more of the Rulings, the making of the Partial Cash Election or the effects of any of the foregoing shall be deemed a material adverse effect to any party hereunder or constitute a basis for any party not to consummate the transactions contemplated hereby.

(b) If the Partial Cash Election has been made, then, notwithstanding any other provision of this Agreement, at the Effective Time: (i) the Berkshire Merger shall not be consummated, (ii) the outstanding Holding Company Stock shall not be cancelled nor will any additional Holding Company stock be issued, (iii) the Transactions will have no effect on Berkshire Common Stock or any Berkshire Option, the Berkshire Certificate of Incorporation and Bylaws, or the Berkshire Board of Directors and officers, except that Ronald E. Ferguson, Chairman and Chief Executive Officer of General, shall be duly appointed as a director of Berkshire (rather than Holding

Annex I-12


Company) immediately after the Effective Time, (iv) all of the rights and obligations of Holding Company shall enure to, or be obligations of, Berkshire, (v) as appropriate, references herein to Holding Company Class A Common Stock and Holding Company Class B Common Stock shall instead refer to Berkshire Class A Common Stock and Berkshire Class B Common Stock, respectively, and (vi) Berkshire shall take any action required so that Merger Sub B is a direct subsidiary of a direct subsidiary of Berkshire.

(c) If the Partial Cash Election has been made, then, notwithstanding
Section 3.4(b), for each issued and outstanding share of General Common Stock (with the associated Rights), the Merger Consideration shall consist of either
(i) the right to receive from Berkshire (A) 0.003395 of a fully paid and nonassessable share of Berkshire Class A Common Stock and (B) an amount in cash equal to the product of .000105 and the Average Trading Price of one share of Berkshire Class A Common Stock, or (ii) the right to receive from Berkshire (x) 0.10185 of a fully paid and nonassessable share of Berkshire Class B Common Stock and (y) an amount in cash equal to the product of .00315 and the Average Trading Price of one share of Berkshire Class B Common Stock, as determined pursuant to the election procedures set forth in Section 3.5(b).

(d) As promptly as practicable after the date hereof, and in any event prior to the filing of the Ruling Request (as defined in Section 6.14(a)), Berkshire shall issue to General shares of a new class of non-voting, non- participating cumulative preferred stock of Berkshire, which shares shall have an aggregate face amount of $1,000,000, shall pay dividends at a market rate and shall be redeemable for their aggregate face amount (plus accrued but unpaid dividends) at Berkshire's option after five years from the date of issuance, and in exchange General shall issue to Berkshire an equal number of shares of a new class of preferred stock of General having equivalent value and substantially identical terms. The preferred stock issued pursuant to this Section 3.7(d) shall not be converted in the Berkshire Merger or the General Merger and shall remain outstanding following the Effective Time.

3.8 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, General Common Stock outstanding immediately prior to the Effective Time and held by a holder who has delivered a written demand for appraisal of such shares in accordance with Section 262 of the DGCL, if such Section 262 provides for appraisal rights for such General Common Stock in the General Merger ("Dissenting Shares"), shall not be converted as provided in Section 3.7(c) hereof, unless and until such holder fails to perfect or effectively withdraws or otherwise loses his right to appraisal and payment under the DGCL. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses his right to appraisal, such Dissenting Shares shall thereupon be treated as if they had been converted as of the Effective Time into the right to receive the Merger Consideration as provided in Section 3.4(b) or Section 3.7(c) hereof, as appropriate, together with any dividends or distributions payable thereon or cash in lieu of fractional shares, and to which such holder is entitled, without interest thereon. General shall give Berkshire prompt notice of any demands received by General for appraisal of General Common Stock, and, prior to the Effective Time, Berkshire shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, General shall not, except with the prior written consent of Berkshire, make any payment with respect to, or offer to settle, any such demands.

Section 4.2 or 4.3, respectively, or to one or more of its covenants contained herein; provided, that the mere inclusion of an item in a Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by a party that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a material adverse effect with respect to any party hereto.

Except as disclosed in Section 4.2(d) of the Disclosure Schedule, the execution and delivery of this Agreement or the Stock Option Agreement does not, and the consummation of the transactions contemplated hereby and thereby and compliance with the provisions hereof and thereof will not, conflict with, or result in any breach or violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of or "put" right with respect to any obligation or to loss of a material benefit under, or result in the creation of any Lien upon any of the properties or assets of General or any of its subsidiaries under, (i) the Certificate of Incorporation or Bylaws of General or the comparable charter or organizational documents of any of its subsidiaries, (ii) any loan or credit agreement, note, bond, mortgage, indenture, lease, contract or other agreement, instrument, permit, concession, franchise or license applicable to General or any of its subsidiaries or their respective properties or assets or (iii) subject to the governmental filings and other matters referred to in the following sentence, any judgment, order, decree, statute, law, ordinance, rule, regulation or arbitration award applicable to General or any of its subsidiaries or their respective properties or assets, other than, in the case of clauses (ii) and
(iii), any such conflicts, breaches, violations, defaults, rights, losses or Liens that individually or in the aggregate could not have a material adverse effect with respect to General or could not prevent, hinder or materially delay the ability of General to consummate the transactions contemplated by this Agreement or the Stock Option Agreement. No consent, approval, order or authorization of, or registration, declaration or filing with, or notice to, any Federal, state or local government or any court, administrative agency or commission or other governmental authority or agency, domestic or foreign (a "Governmental Entity"), is required by or with respect to General or any of its subsidiaries in connection with the execution and delivery of this Agreement or the Stock Option Agreement by General or the consummation by General of the transactions contemplated hereby and thereby, except for (i) the filing of a premerger notification and report form by General under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), (ii) the filing with the Securities and Exchange Commission (the "SEC") of (y) the Proxy Statement/Prospectus, and (z) such reports or schedules under the Exchange Act as may be required in connection with this Agreement or the Stock Option Agreement and the transactions contemplated by this Agreement and the Stock Option Agreement, (iii) the filing of the Certificates of Merger for the Mergers with the Secretary of State of the State of Delaware, and appropriate documents with the relevant authorities of other states in which General is qualified to do business, (iv) the filing of appropriate

(e) SEC Documents; Undisclosed Liabilities. General has filed all required reports, schedules, forms, statements and other documents with the SEC since January 1, 1996 (collectively, and in each case including all exhibits and schedules thereto and documents incorporated by reference therein, the "General SEC Documents"). As of their respective dates, General SEC Documents complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to such General SEC Documents, and none of General SEC Documents (including any and all financial statements included therein) as of such dates contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The consolidated financial statements of General included in General SEC Documents (the "General SEC Financial Statements") comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with generally accepted accounting principles (except, in the case of unaudited consolidated quarterly statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly present the consolidated financial position of General and its consolidated subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods then ended (subject, in the case of unaudited quarterly statements, to normal year-end audit adjustments). Since December 31, 1997, neither General nor any of its subsidiaries has incurred any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) except (i) as and to the extent set forth on the audited balance sheet of General and its subsidiaries as of December 31, 1997 (including the notes thereto), (ii) as incurred in connection with the transactions contemplated by this Agreement or the Stock Option Agreement, (iii) as incurred after December 31, 1997 in the ordinary course of business and consistent with past practice, (iv) as described in General SEC Documents filed since December 31, 1997 (the "Recent General SEC Documents"), or (v) as would not, individually or in the aggregate, have a material adverse effect with respect to General.

(f) Information Supplied. None of the information supplied or to be supplied by General for inclusion or incorporation by reference in (i) the registration statement on Form S-4 to be filed with the SEC by Holding Company in connection with the issuance of Holding Company Common Stock in the Transactions (the "Form S-4") will, at the time the Form S-4 is filed with the SEC, and at any time it is amended or supplemented or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) the Proxy Statement/Prospectus will, at the date it is first mailed to General's stockholders and the Berkshire's stockholders or at the time of General Stockholders Meeting (as defined in Section 6.1(b)) and the Berkshire Stockholders Meeting (as defined in Section 6.1(c)), contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. The Proxy Statement/Prospectus will comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder, except that no representation is made by General with respect to statements made or incorporated by reference therein based on information supplied by Berkshire or Holding Company for inclusion or incorporation by reference therein.

(g) Absence of Certain Changes or Events. Except as disclosed in the Recent General SEC Documents or in Section 4.2(g) of the Disclosure Schedule, since December 31, 1997, General has conducted its business only in the ordinary course consistent with past practice, and there is not and has not been: (i) any material adverse change with respect to General; (ii) any condition, event or occurrence which, individually or in the aggregate, could reasonably be expected to have a material adverse effect or give rise to a material adverse change with

Annex I-16


respect to General; (iii) any event which, if it had taken place following the execution of this Agreement, would not have been permitted by Section 5.1 without the prior consent of Berkshire; or (iv) any condition, event or occurrence which would prevent, hinder or materially delay the ability of General to consummate the transactions contemplated by this Agreement or the Stock Option Agreement.

(h) Litigation; Labor Matters; Compliance with Laws.

(i) Except as disclosed in the Recent General SEC Documents, there is no suit, action or proceeding or investigation pending or, to the knowledge of General, threatened against or affecting General or any of its subsidiaries or any basis for any such suit, action, proceeding or investigation that, individually or in the aggregate, could reasonably be expected to have a material adverse effect with respect to General or prevent, hinder or materially delay the ability of General to consummate the transactions contemplated by this Agreement or the Stock Option Agreement, nor is there any judgment, decree, injunction, rule or order of any Governmental Entity or arbitrator outstanding against General or any of its subsidiaries having, or which, insofar as reasonably could be foreseen by General, in the future could have, any such effect.

(ii) Neither General nor any of its subsidiaries is a party to, or bound by, any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization, nor is it or any of its subsidiaries the subject of any proceeding asserting that it or any subsidiary has committed an unfair labor practice or seeking to compel it to bargain with any labor organization as to wages or conditions of employment nor is there any strike, work stoppage or other labor dispute involving it or any of its subsidiaries pending or, to its knowledge, threatened, any of which could have a material adverse effect with respect to General.

(iii) The conduct of the business of each of General and each of its subsidiaries complies with all statutes, laws, regulations, ordinances, rules, judgments, orders, decrees or arbitration awards applicable thereto, except for violations or failures so to comply, if any, that, individually or in the aggregate, could not reasonably be expected to have a material adverse effect with respect to General.

(i) Employee Matters. General has delivered or made available to Berkshire full and complete copies or descriptions of each material employment, severance, bonus, profit sharing, compensation, termination, stock option, stock appreciation right, restricted stock, phantom stock, performance unit, pension, retirement, deferred compensation, welfare or other employee benefit agreement, trust fund or other arrangement and any union, guild or collective bargaining agreement maintained or contributed to or required to be contributed to by General or any of its ERISA Affiliates, for the benefit or welfare of any director, officer, employee or former employee of General or any of its ERISA Affiliates (such plans and arrangements being collectively the "General Benefit Plans"). Each of General Benefit Plans is in material compliance with all applicable laws including ERISA and the Code. The Internal Revenue Service has determined that each General Benefit Plan that is intended to be a qualified plan under Section 401(a) of the Code is so qualified and General is aware of no event occurring after the date of such determination that would adversely affect such determination. The liabilities accrued under each such plan are reflected on the latest balance sheet of General included in the Recent SEC Reports in accordance with generally accepted accounting principles applied on a consistent basis. No condition exists that is reasonably likely to subject General or any of its subsidiaries to any direct or indirect liability under Title IV of ERISA or to a civil penalty under
Section 502(j) of ERISA or liability under Section 4069 of ERISA or 4975, 4976, or 4980B of the Code or the loss of a federal tax deduction under
Section 280G of the Code or other liability with respect to General Benefit Plans that would have a material adverse effect on General and that is not reflected on such balance sheet. No General Benefit Plan (other than any General Benefit Plan that is a "multiemployer plan" as such term is defined in
Section 4001(a)(3) of ERISA) is subject to Title IV of ERISA. There are no pending, threatened, or anticipated claims (other than routine claims for benefits or immaterial claims) by, on behalf of or against any of General Benefit Plans or any trusts related thereto. "ERISA Affiliate" means, with respect to any person, any trade or business, whether or not incorporated, that together with such person would be deemed a "single employer" within the meaning of Section 4001(a)(15) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

Annex I-17

Except as set forth in Section 4.2(j) of the Disclosure Schedule: (i) no material claim for unpaid Taxes has been asserted against General or any of its subsidiaries in writing by a Tax authority or has become a lien (except for liens for Taxes not yet due and payable or for Taxes that are being disputed in good faith by appropriate proceedings and that have been reserved against in accordance with generally accepted accounting principles) against the property of General or any of its subsidiaries, (ii) no audit of any Tax Return of General or any of its subsidiaries is being conducted by a Tax authority, and (iii) no extension of the statute of limitations on the assessment of any Taxes has been granted by General or any of its subsidiaries and is currently in effect. Neither General nor any of its Subsidiaries is or has been a member of any consolidated, combined, unitary or aggregate group for Tax purposes except such a group consisting only of General and its subsidiaries. As used herein, "Taxes" shall mean all taxes of any kind, including, without limitation, those on or measured by or referred to as income, gross receipts, sales, use, ad valorem, franchise, profits, license, withholding, payroll, employment, excise, severance, stamp, occupation, premium, value added, property or windfall profits taxes, customs, duties or similar fees, assessments or charges of any kind whatsoever, together with any interest and any penalties, additions to tax or additional amounts imposed by any governmental authority, domestic or foreign. As used herein, "Tax Return" shall mean any return, report or statement required to be filed with any governmental authority with respect to Taxes.

(k) State Antitakeover Laws Not Applicable; No Other Restrictions. The Board of Directors of General has approved this Agreement and the Stock Option Agreement and the transactions contemplated hereby and thereby and such approval constitutes approval of the Transactions and the General Merger and the Stock Option Agreement and the other transactions contemplated hereby and thereby by the Board of Directors of General under the provisions of Section 203 of the DGCL and Article VIII of General's Certificate of Incorporation such that Section 203 of the DGCL and such Article VIII do not apply to this Agreement or the Stock Option Agreement or the transactions contemplated hereby or thereby. No other state takeover statute or similar statute or regulation of the State of Delaware (or, to the knowledge of General after due inquiry, of any other state or jurisdiction) applies or purports to apply to this Agreement or the Stock Option Agreement or the transactions contemplated hereby or thereby. No provision of the Certificate of Incorporation, Bylaws or other governing instruments of General or any of its subsidiaries or the terms of any rights plan or agreement of General (including the Rights Agreement) would, directly or indirectly, restrict or impair (i) the ability of Berkshire or Holding Company to vote, or otherwise to exercise the rights of a stockholder with respect to, securities of General and its subsidiaries that may be acquired or controlled by Berkshire or Holding Company by virtue of this Agreement or the Stock Option Agreement, the transactions contemplated hereby or thereby or (ii) the rights granted hereunder and thereunder, including without limitation, the right to cause General to repurchase options or equity securities pursuant to the Stock Option Agreement, or permit any stockholder to acquire securities of General, Berkshire or Holding Company, or any of their respective subsidiaries on a basis not available to Berkshire or Holding Company in the event that Berkshire or Holding Company were to acquire securities of General.

(l) Environmental Matters. There are no legal, administrative, arbitral or other proceedings, claims, actions, causes of action, private environmental investigations or remediation activities or governmental investigations of any nature seeking to impose, or that reasonably could be expected to result in the imposition, on General or any of its subsidiaries of any liability or obligations arising under common law standards relating to environmental protection, human health or safety, or under any local, state, federal, national or supernational environmental statute, regulation or ordinance, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (collectively, "Environmental Laws"), pending or, to the knowledge of General, threatened, against General or any of its subsidiaries, which liability or obligation would have or would reasonably be expected to have a material adverse effect on General or any of its subsidiaries. To

Annex I-18


the knowledge of General or any of its subsidiaries, there is no reasonable basis for any such proceeding, claim, action or governmental investigation that would impose any liability or obligation that would have or would reasonably be expected to have a material adverse effect on General or any of its subsidiaries. To the knowledge of General, during or prior to the period of (i) its or any of its subsidiaries' ownership or operation of any of their respective current properties, (ii) its or any of its subsidiaries' participation in the management of any property, or (iii) its or any of its subsidiaries' holding of a security interest or other interest in any property, there was no release or threatened release of hazardous, toxic, radioactive or dangerous materials or other materials regulated under Environmental Laws in, on, under or affecting any such property which would reasonably be expected to have a material adverse effect on General or any of its subsidiaries. Neither General nor any of its subsidiaries is subject to any agreement, order, judgment, decree, letter or memorandum by or with any court, governmental authority, regulatory agency or third party imposing any material liability or obligations pursuant to or under any Environmental Law that would have or would reasonably be expected to have a material adverse effect on General or any of its subsidiaries.

(m) Properties. Except as disclosed in the Recent General SEC Documents, each of General and its subsidiaries (i) has good, clear and marketable title to all the properties and assets reflected in the latest audited balance sheet included in such Recent General SEC Documents as being owned by General or one of its subsidiaries or acquired after the date thereof which are, individually or in the aggregate, material to General's business on a consolidated basis (except properties and assets sold or otherwise disposed of since the date thereof in the ordinary course of business), free and clear of (A) all Liens except (1) statutory liens securing payments not yet due and (2) such imperfections or irregularities of title or other Liens (other than real property mortgages or deeds of trust) as do not materially affect the use of the properties or assets subject thereto or affected thereby or otherwise materially impair business operations at such properties, and (B) all real property mortgages and deeds of trust and (ii) is the lessee of all leasehold estates reflected in the latest audited financial statements included in such Recent General SEC Documents or acquired after the date thereof which are material to its business on a consolidated basis and is in possession of the properties purported to be leased thereunder, and each such lease is valid without default thereunder by the lessee or, to General's knowledge, the lessor.

(n) Insurance Matters.

(i) Except as otherwise would not, individually or in the aggregate, be reasonably likely to have a material adverse effect, all policies, binders, slips, certificates, annuity contracts and participation agreements and other agreements of insurance, whether individual or group, in effect as of the date hereof (including all applications, supplements, endorsements, riders and ancillary agreements in connection therewith) that are issued by General or its subsidiaries (the "General Insurance Contracts") and any and all marketing materials, are, to the extent required under applicable law, on forms approved by applicable insurance regulatory authorities or which have been filed and not objected to by such authorities within the period provided for objection, and such forms comply in all material respects with the insurance statutes, regulations and rules applicable thereto and, as to premium rates established by General or any subsidiary which are required to be filed with or approved by insurance regulatory authorities, the rates have been so filed or approved, the premiums charged conform thereto in all material respects, and such premiums comply in all material respects with the insurance statutes, regulations and rules applicable thereto.

Annex I-19

Such reserves were adequate in the aggregate to cover the total amount of all reasonably anticipated liabilities of General and each of its Subsidiaries under all outstanding insurance, reinsurance and other applicable agreements as of the respective dates of such General statutory accounting statements. The admitted assets of General and each of its subsidiaries as determined under applicable laws are in an amount at least equal to the minimum amounts required by applicable laws.

(ii) Except for regular periodic assessments in the ordinary course of business or assessments based on developments which are publicly known within the insurance industry, to the knowledge of General, no claim or assessment is pending or threatened against any subsidiary which is peculiar or unique to such subsidiary by any state insurance guaranty associations in connection with such association's fund relating to insolvent insurers which if determined adversely, would, individually or in the aggregate, be reasonably likely to have a material adverse effect.

Annex I-22

(f) Information Supplied. None of the information supplied or to be supplied by Berkshire or Holding Company for inclusion or incorporation by reference in
(i) the Form S-4 will, at the time the Form S-4 is filed with the SEC, and at any time it is amended or supplemented or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) the Proxy Statement/Prospectus will, at the date the Proxy Statement/Prospectus is first mailed to General's stockholders and the Berkshire's stockholders or at the time of General Stockholders Meeting and the Berkshire Stockholders Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. The Form S-4 and Proxy Statement/Prospectus will comply as to form in all material respects with the requirements of the Securities Act and Exchange Act and the rules and regulations promulgated thereunder, except that no representation or warranty is made by Berkshire or Holding Company with respect to statements made or incorporated by reference therein based on information supplied by General for inclusion or incorporation by reference therein.

(h) Compliance with Laws. The conduct of the business of each of Berkshire and each of its subsidiaries complies with all statutes, laws, regulations, ordinances, rules, judgments, orders, decrees or arbitration awards applicable thereto, except for violations or failures so to comply, if any, that, individually or in the aggregate, could not reasonably be expected to have a material adverse effect with respect to Berkshire.

(i) State Antitakeover Laws Not Applicable; No Other Restrictions. No state takeover statute or similar statute or regulation of the State of Delaware (or, to the knowledge of Berkshire after due inquiry, of any other state or jurisdiction) applies or purports to apply to this Agreement or the transactions contemplated hereby. No provision of the Certificate of Incorporation, Bylaws or other governing instruments of Berkshire or any of its subsidiaries would, directly or indirectly, restrict or impair (i) the ability of Holding Company to vote, or

Annex I-23


otherwise to exercise the rights of a stockholder with respect to, securities of Berkshire and its subsidiaries that may be acquired or controlled by Holding Company by virtue of this Agreement or the transactions contemplated hereby or (ii) the rights granted hereunder, or permit any stockholder to acquire securities of Berkshire or any of its subsidiaries on a basis not available to Holding Company in the event that Holding Company were to acquire securities of Berkshire.

General or Holding Company, as the case may be, will pay all expenses of each Indemnified Party in advance of the final disposition of any such action or proceeding, to the fullest extent permitted by law upon receipt of any undertaking contemplated by Section 145(e) of the DGCL.

Any Indemnified Party wishing to claim indemnification under this Section 6.5, upon learning of any such claim, action, suit, proceeding or investigation, shall notify General and Holding Company (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 6.5 except to the extent such failure prejudices such party), and shall deliver to General (or after the Effective Time, Holding Company) the undertaking contemplated by

Annex I-28


Section 145(e) of the DGCL. The Indemnified Parties as a group may retain only one law firm to represent them with respect to each such matter unless there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of any two or more Indemnified Parties.

ANNEX II

STOCK OPTION AGREEMENT

THIS STOCK OPTION AGREEMENT (the "Agreement") is entered into as of June 19, 1998 by and between General Re Corporation, a Delaware corporation (the "Grantor"), and Berkshire Hathaway Inc., a Delaware corporation (the "Grantee").

WHEREAS, the Grantee and the Grantor are entering into an Agreement and Plan of Mergers, dated as of the date hereof (the "Merger Agreement"), which provides, among other things, for the merger of a subsidiary of NBH, Inc., a Delaware corporation, into Grantor (such merger, along with the other transactions contemplated by the Merger Agreement, the "Transactions");

WHEREAS, as a condition and inducement to Grantee's willingness to enter into the Merger Agreement, the Grantee has requested that the Grantor grant to the Grantee an option to purchase up to 15,000,000 shares of Common Stock, par value $0.50 per share, of the Grantor (the "Common Stock"), upon the terms and subject to the conditions hereof; and

WHEREAS, in order to induce the Grantee to enter into the Merger Agreement, the Grantor is willing to grant the Grantee the requested option.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereto agree as follows:

1. The Option; Exercise; Adjustments; Payment of Spread.

(a) Contemporaneously herewith the Grantee and the Grantor are entering into the Merger Agreement. Subject to the other terms and conditions set forth herein, the Grantor hereby grants to the Grantee an irrevocable option (the "Option") to purchase up to 15,000,000 (as may be adjusted as provided herein) shares of Common Stock (together with rights attached thereto to purchase Series A Junior Participating Preferred Stock of the Company issued pursuant to the Rights Agreement (the "Rights Agreement") dated as of September 11, 1991 between the Company and Bank of New York, as rights agent) (the "Shares") at a cash purchase price equal to $283.71 per share (the "Purchase Price"). The Option may be exercised by the Grantee, in whole or in part, at any time, or from time to time, following the occurrence of one of the events set forth in Section 2(d) hereof, and prior to the termination of the Option in accordance with the terms of this Agreement.

(b) In the event the Grantee wishes to exercise the Option, the Grantee shall send a written notice to the Grantor (the "Stock Exercise Notice") specifying a date for the closing of such purchases (subject to the HSR Act (as defined below) and applicable insurance regulatory approvals) not later than 10 business days and not earlier than three business days following the date such notice is given. In the event of any change in the number of issued and outstanding shares of Common Stock by reason of any stock dividend, stock split, split-up, recapitalization, reorganization or other change in the corporate or capital structure of the Grantor, the number and/or kind of Shares subject to this Option and the purchase price per Share shall be appropriately adjusted to restore the Grantee to its rights hereunder, including its right to purchase Shares representing 19.9% of the capital stock of the Grantor entitled to vote generally for the election of the directors of the Grantor which is issued and outstanding immediately prior to the exercise of the Option at an aggregate purchase price equal to the Purchase Price multiplied by 15,000,000. In the event that any additional shares of Common Stock are issued after the date of this Agreement (other than pursuant to an event described in the preceding sentence), the number of Shares subject to this Option shall be increased by 19.9% of the number of the additional shares of Common Stock so issued (and such additional Shares shall have a purchase price per share equal to the Purchase Price). Notwithstanding anything in this Agreement, the number of shares subject to this Option shall never exceed 19.9% of the outstanding shares of the Grantor.

Annex II-1


(c) At any time when the Option is exercisable pursuant to the terms of
Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to purchase Shares as provided in Section 1(a) hereof, to send a written notice to the Grantor (the "Cash Exercise Notice") specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given on which date the Grantor shall pay to the Grantee an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Shares subject to the Option as Grantee shall specify in such notice. As used herein "Spread" shall mean the excess, if any, over the Purchase Price of the higher of (y) if applicable, the highest price per share of Common Stock (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid or proposed to be paid by any person pursuant to any General Takeover Proposal (as defined in the Merger Agreement) (the "Alternative Purchase Price") or
(z) the closing price of the shares of Common Stock on the NYSE Composite Tape on the last trading day immediately prior to the date of the Cash Exercise Notice (the "Closing Price"). If the Alternative Purchase Price includes any property other than cash, the Alternative Purchase Price shall be the sum of (i) the fixed cash amount, if any, included in the Alternative Purchase Price plus (ii) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing prices (or the average of the closing bid and asked prices if closing prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date of the Cash Exercise Notice shall be deemed to equal the fair market value of such property. If such other property consists of something other than cash or securities with an existing public trading market and, as of the payment date for the Spread, agreement on the value of such other property has not been reached, the Alternative Purchase Price shall be deemed to equal the Closing Price. Upon the Grantee's exercise of its right to receive cash pursuant to this
Section 1(c), the obligations of the Grantor to deliver Shares pursuant to
Section 3 shall be terminated with respect to such number of Shares for which the Grantee shall have been paid the Spread.

2. Conditions to Delivery of Shares. The Grantor's obligation to deliver Shares upon exercise of the Option is subject only to the conditions that:

(a) No preliminary or permanent injunction or other order issued by any federal or state court of competent jurisdiction in the United States prohibiting the delivery of the Shares shall be in effect; and

(b) Any applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated; and

(c) Any other consent, approval, order, notification, or authorization, the failure of which to obtain or make would make the issuance of the Shares illegal, shall have been obtained or made and be in full force and effect; and

(d) (i) any person (other than Grantee or any of its subsidiaries) shall have acquired beneficial ownership (as such term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) or the right to acquire beneficial ownership of, or any "group" (as such term is defined under the Exchange Act) shall have been formed which beneficially owns or has the right to acquire beneficial ownership of, shares of Common Stock aggregating 20% or more of the then outstanding Common Stock; (ii) the Merger Agreement shall have been terminated by Grantor pursuant to Section 8.1(g) of the Merger Agreement; or (iii) either (A) a General Takeover Proposal shall have been made to Grantor or any of its subsidiaries or any of its stockholders or any person shall have publicly announced an intention (whether or not conditional) to make a General Takeover Proposal with respect to Grantor or any of its subsidiaries and thereafter the Merger Agreement shall have been terminated by either Grantee or Grantor pursuant to Section 8.1(d) of the Merger Agreement, or (B) the Merger Agreement shall have been terminated by Grantee pursuant to Section 8.1(f) of the Merger Agreement, and, in the case of either clause (A) or clause (B), within 18 months of the date of such termination Grantee enters into any General Acquisition Agreement (as defined in the Merger Agreement). As used in this Agreement, "person" shall have the meaning specified in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.

Annex II-2


3. The Closing.

(a) Any closing hereunder shall take place on the date specified by the Grantee in its Stock Exercise Notice or Cash Exercise Notice, as the case may be, at 9:00 A.M., local time, at the offices of Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street, New York, New York, or, if the conditions set forth in Section 2(a), (b) or (c) have not then been satisfied, on the second business day following the satisfaction of such conditions, or at such other time and place as the parties hereto may agree (the "Closing Date"). On the Closing Date, (i) in the event of a closing pursuant to
Section 1(b) hereof, the Grantor will deliver to the Grantee a certificate or certificates, representing the Shares in the denominations designated by the Grantee in its Stock Exercise Notice and the Grantee will purchase such Shares from the Grantor at the price per Share equal to the Purchase Price or (ii) in the event of a closing pursuant to Section 1(c) hereof, the Grantor will deliver to the Grantee cash in an amount determined pursuant to Section 1(c) hereof. Any payment made by the Grantee to the Grantor, or by the Grantor to the Grantee, pursuant to this Agreement shall be made by wire transfer to a bank designated by the party receiving such funds.

(b) The certificates representing the Shares shall bear an appropriate legend relating to the fact that such Shares have not been registered under the Securities Act of 1933, as amended (the "Securities Act").

4. Representations and Warranties of the Grantor. The Grantor represents and warrants to the Grantee that (a) the Grantor is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has the requisite corporate power and authority to enter into and perform this Agreement; (b) the execution and delivery of this Agreement by the Grantor and the consummation by it of the transactions contemplated hereby have been duly authorized by the Board of Directors of the Grantor and this Agreement has been duly executed and delivered by a duly authorized officer of the Grantor and constitutes a valid and binding obligation of the Grantor, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general principles of equity; (c) the Grantor has taken all necessary corporate action to authorize and reserve the Shares issuable upon exercise of the Option and the Shares, when issued and delivered by the Grantor upon exercise of the Option and paid for by Grantee as contemplated hereby, will be duly authorized, validly issued, fully paid and non-assessable and free of preemptive rights; (d) the execution and delivery of this Agreement by the Grantor and, except as otherwise required by the HSR Act and applicable insurance laws and for such filings as are required by the New York Stock Exchange, Inc. ("NYSE"), the consummation by it of the transactions contemplated hereby do not require the consent, waiver, approval or authorization of or any filing with any person or public authority and will not violate, result in a breach of or the acceleration of any obligation under, or constitute a default under, any provision of Grantor's certificate of incorporation or bylaws, or any material indenture, mortgage, lien, lease, agreement, contract, instrument, order, law, rule, regulation, judgment, ordinance, or decree, or restriction by which the Grantor or any of its subsidiaries or any of their respective properties or assets is bound; (e) no "fair price," "moratorium," "control share acquisition," "interested shareholder" or other form of antitakeover statute or regulation, including without limitation, Section 203 of the Delaware General Corporation Law, or similar provision contained in the certificate of incorporation or bylaws of Grantor, is or shall be applicable to any of the transactions contemplated by this Agreement, and the Board of Directors of the Company has taken all action to approve the transactions contemplated hereby to the extent necessary to avoid any such application (including, without limitation, the Board of Directors of the Company having determined pursuant to Article IX of the Company's Restated Certification of Incorporation that the purchase price under Sections 7 and 8 hereof will not violate or require any shareholder vote under Article X thereof); and (f) the Grantor has taken all corporate action necessary so that the grant and any subsequent exercise of the Option by the Grantee or other exercise by the Grantee of any its rights hereunder will not result in the separation or exercisability of the rights under the Rights Agreement or in any nullification of rights under the Rights Agreement held by the Grantee or any of its Affiliates or Associates (as defined in the Rights Agreement).

5. Representations And Warranties of The Grantee. The Grantee represents and warrants to the Grantor that (a) the execution and delivery of this Agreement by the Grantee and the consummation by it of the

Annex II-3


transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of the Grantee and this Agreement has been duly executed and delivered by a duly authorized officer of the Grantee and constitutes a valid and binding obligation of Grantee; and (b) the Grantee is acquiring the Option and, if and when it exercises the Option, will be acquiring the Shares issuable upon the exercise thereof for its own account and not with a view to distribution or resale in any manner which would be in violation of the Securities Act.

6. Listing of Shares; Filings; Governmental Consents. Subject to applicable law and the rules and regulations of the NYSE, when the Option becomes exercisable hereunder, the Grantor will promptly file an application to list the Shares on the NYSE and will use all reasonable best efforts to obtain approval of such listing and to effect all necessary filings by the Grantor under the HSR Act and the applicable insurance laws of each state and foreign jurisdiction; provided, however, that if the Grantor is unable to effect such listing on the NYSE by the Closing Date, the Grantor will nevertheless be obligated to deliver the Shares upon the Closing Date. Each of the parties hereto will use its reasonable best efforts to obtain consents of all third parties and governmental authorities, if any, necessary to the consummation of the transactions contemplated.

7. Repurchase of Shares. If within 18 months after the date the Merger Agreement was terminated pursuant to the terms thereof (the "Merger Termination Date"), neither the Grantee nor any other person has acquired more than fifty percent (excluding the Shares) of the shares of outstanding Common Stock, the Grantor will then have the right to purchase (the "Repurchase Right") all, but not less than all, of the Shares acquired upon exercise of this Option of which the Grantee is the beneficial owner on the date the Grantor gives written notice of its intention to exercise the Repurchase Right, at the greater of (i) the Purchase Price or (ii) the average of the last sales prices for shares of Common Stock on the 30 trading days ending on the date the Grantor gives written notice of its intention to exercise the Repurchase Right. If the Grantor does not exercise the Repurchase Right within thirty days following the date the Repurchase Right becomes exercisable, the Repurchase Right will expire and cannot thereafter be exercised. In the event the Grantor wishes to exercise the Repurchase Right, the Grantor shall send a written notice to the Grantee specifying a date (not later than 20 business days and not earlier than 10 business days following the date such notice is given) for the closing of such purchase.

8. Sale of Shares. At any time prior to the date that is 18 months after the Merger Termination Date, the Grantee shall have the right to sell (the "Sale Right") to the Grantor all, but not less than all, of the Shares acquired upon exercise of this Option of which the Grantee is the beneficial owner on the date the Grantee gives written notice of its intention to exercise the Sale Right, at the greater of (i) the Purchase Price, or (ii) the average of the last sales prices for shares of Common Stock on the 30 trading days ending on the date the Grantee gives written notice of its intention to exercise the Sale Right. If the Grantee does not exercise the Sale Right within thirty days following the date the Sale Right becomes exercisable, the Sale Right will expire and cannot thereafter be exercised. In the event the Grantee wishes to exercise the Sale Right, the Grantee shall send a written notice to the Grantor specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given for the closing of such sale.

9. Registration Rights.

(a) In the event that the Grantee shall desire to sell any of the Shares within three years after the purchase of such Shares pursuant hereto, and such sale requires, in the opinion of counsel to the Grantee, which opinion shall be reasonably satisfactory to the Grantor and its counsel, registration of such Shares under the Securities Act, the Grantor will cooperate with the Grantee and any underwriters in registering such Shares for resale, including, without limitation, promptly filing a registration statement which complies with the requirements of applicable federal and state securities laws, and entering into an underwriting agreement with such underwriters upon such terms and conditions as are customarily contained in underwriting agreements with respect to secondary distributions; provided that the Grantor shall not be required to have declared effective more than two registration statements hereunder and shall be entitled to delay the filing or effectiveness of any registration statement for up to 90 days if the offering would, in the judgment of the Board of Directors of the Grantor, require premature disclosure of any material corporate development or material transaction involving the Grantor or interfere with any previously planned securities offering by the Grantor.

Annex II-4


(b) If the Common Stock is registered pursuant to the provisions of this
Section 9, the Grantor agrees (i) to furnish copies of the registration statement and the prospectus relating to the Shares covered thereby in such numbers as the Grantee may from time to time reasonably request and (ii) if any event shall occur as a result of which it becomes necessary to amend or supplement any registration statement or prospectus, to prepare and file under the applicable securities laws such amendments and supplements as may be necessary to keep available for at least 90 days a prospectus covering the Common Stock meeting the requirements of such securities laws, and to furnish the Grantee such numbers of copies of the registration statement and prospectus as amended or supplemented as may reasonably be requested. The Grantor shall bear the cost of the registration, including, but not limited to, all registration and filing fees, printing expenses, and fees and disbursements of counsel and accountants for the Grantor, except that the Grantee shall pay the fees and disbursements of its counsel, and the underwriting fees and selling commissions applicable to the shares of Common Stock sold by the Grantee. The Grantor shall indemnify and hold harmless (i) Grantee, its affiliates and its officers and directors and each person who controls Grantee within the meaning of the Securities Act or Exchange Act and (ii) each underwriter and each person who controls any underwriter within the meaning of the Securities Act or the Exchange Act (collectively, the "Underwriters") ((i) and (ii) being referred to as "Indemnified Parties") against any losses, claims, damages, liabilities or expenses, to which the Indemnified Parties may become subject, insofar as such losses, claims, damages, liabilities (or actions in respect thereof) and expenses arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained or incorporated by reference in any registration statement or prospectus filed pursuant to this paragraph, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Grantor will not be liable in any such case to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any such documents in reliance upon and in conformity with written information furnished to the Grantor by the Indemnified Parties expressly for use or incorporation by reference therein.

(c) The Grantee and the Underwriters shall indemnify and hold harmless the Grantor, its affiliates and its officers and directors and each person who controls Grantee within the meaning of the Securities Act or Exchange Act against any losses, claims, damages, liabilities or expenses to which the Grantor, its affiliates and its officers and directors may become subject, insofar as such losses, claims, damages, liabilities (or actions in respect thereof) and expenses arise out of or are based upon any untrue statement of any material fact contained or incorporated by reference in any registration statement filed pursuant to this paragraph, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Grantor by the Grantee or the Underwriters, as applicable, specifically for use or incorporation by reference therein.

10. Expenses. Each party hereto shall pay its own expenses incurred in connection with this Agreement, except as otherwise specifically provided herein.

11. Specific Performance. The Grantor acknowledges that if the Grantor fails to perform any of its obligations under this Agreement immediate and irreparable harm or injury would be caused to the Grantee for which money damages would not be an adequate remedy. In such event, the Grantor agrees that the Grantee shall have the right, in addition to any other rights it may have, to specific performance of this Agreement. Accordingly, if the Grantee should institute an action or proceeding seeking specific enforcement of the provisions hereof, the Grantor hereby waives the claim or defense that the Grantee has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists. The Grantor further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief.

Annex II-5

(d) As used herein, the term "Notional Total Profit" with respect to any number of Shares as to which Grantee may propose to exercise this Option shall be the Total Profit determined as of the date of the Stock Exercise Notice assuming that this Option were exercised on such date for such number of Shares and assuming that such Shares, together with all other Shares acquired upon exercise of the Option and held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions).

ANNEX IV

OPINION OF GOLDMAN, SACHS & CO.

June 19, 1998

Board of Directors
General Re Corporation
Financial Center
695 East Main Street
Stamford, CT 06904

Gentlemen and Mesdames:

You have requested our opinion as to the fairness from a financial point of view to the holders of the outstanding shares of common stock, par value $0.50 per share (the "Company Common Stock"), of General Re Corporation (the "Company") of the Merger Consideration to be received by such holders in the proposed Transactions (as each such term is defined herein) pursuant to the Agreement and Plan of Mergers, dated June 19, 1998 (the "Agreement"), by and between Berkshire Hathaway Inc. ("Berkshire") and the Company.

The Agreement contemplates, subject to the right of Berkshire to elect to effect the Alternative Company Merger Transaction (as defined below), two contemporaneous merger transactions pursuant to which each of the Company and Berkshire would become a subsidiary of NBH, Inc., a holding company which will be renamed Berkshire Hathaway ("New Berkshire"). Pursuant to the Company merger transaction (the "Company Merger Transaction"), each issued and outstanding share of Company Common Stock (other than shares owned by Berkshire) will be converted into the following (the consideration described in (i) and (ii) immediately below being the "Company Merger Transaction Consideration"): (i) the right to receive either (A) 0.0035 of a share of the Class A common stock, par value $5.00 per share, of New Berkshire ("New Berkshire Class A Common Stock"), or (B) 0.105 of a share of the Class B common stock, par value $0.1667 per share, of New Berkshire ("New Berkshire Class B Common Stock"), as determined pursuant to the election procedures set forth in the Agreement. Pursuant to the Berkshire merger transaction (the "Berkshire Merger Transaction"), each issued and outstanding share of the Class A common stock, par value $5.00 per share, of Berkshire (the "Berkshire Class A Common Stock") will be converted into one share of New Berkshire Class A Common Stock and each issued and outstanding share of Class B common stock, par value $0.1667 per share, of Berkshire (the "Berkshire Class B Common Stock" and, together with the Berkshire Class A Common Stock, the "Berkshire Common Stock") will be converted into one share of New Berkshire Class B Common Stock. Alternatively, if Berkshire elects, under the circumstances described in the Agreement, to pay 3% of the aggregate merger consideration in cash and to consummate an alternative merger transaction (the "Alternative Company Merger Transaction", and collectively with the Company Merger Transaction, the "Transactions"), neither the Company Merger Transaction nor the Berkshire Merger Transaction shall occur and, pursuant to the Alternative Company Merger Transaction, the Company would become a subsidiary of Berkshire. Pursuant to the Alternative Company Merger Transaction, each issued and outstanding share of Company Common Stock (other than shares owned by Berkshire) will be converted into the following (the consideration described in (i) and (ii) immediately below being the "Alternative Company Merger Transaction Consideration", and collectively with the Company Merger Transaction Consideration, the "Merger Consideration"): the right to receive either (A) (x) 0.003395 of a share of Berkshire Class A Common Stock and (y) an amount in cash equal to the product of 0.000105 and the Average Trading Price (as defined in the Agreement), or (B) (x) 0.10185 of a share of Berkshire Class B Common Stock and (y) an amount in cash equal to the product of 0.00315 and the Average Trading Price, as determined pursuant to the election procedures set forth in the Agreement. Pursuant to the Agreement, in the Transactions, holders of shares of Company Common Stock may elect (a "Class A Election") to have their shares converted into New Berkshire Class A Common Stock or Berkshire Class A Common Stock, as the case

Annex IV-1


may be, to the extent that they would receive a whole number of shares of such Class A Common Stock, with any excess consideration being paid in the form of shares of New Berkshire Class B Common Stock or Berkshire Class B Common Stock, as the case may be (subject to a cash payment for any fractional shares of such Class B Common Stock). Holders of shares of Company Common Stock who do not make a Class A Election will receive shares of New Berkshire Class B Common Stock or Berkshire Class B Common Stock, as the case may be (subject to a cash payment for any fractional shares of such Class B Common Stock).

Goldman, Sachs & Co., as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. We are familiar with the Company, having acted as its financial advisor in connection with, and having participated in certain of the negotiations leading to, the Agreement. We are familiar with Berkshire, having acted in 1996 as co-manager of Berkshire's public offering of $500 million principal amount of 1.00% Senior Exchangeable Notes due December 2, 2001. Goldman, Sachs & Co. provides a full range of financial, advisory and brokerage services and, in the course of its normal trading activities, may from time to time effect transactions and hold positions in the securities or options on securities of the Company and/or Berkshire for its own account and/or for the accounts of customers.

In connection with this opinion, we have reviewed, among other things, the Agreement; Annual Reports to Shareholders and Annual Reports on Form 10-K for the five years ended December 31, 1997 of the Company and Berkshire; certain interim reports to shareholders and Quarterly Reports on Form 10-Q of the Company and Berkshire; Statutory Annual Statements filed by certain insurance subsidiaries of the Company and Berkshire with the Insurance Departments of the States under the laws of which they are respectively organized for the five years ended December 31, 1997; certain interim statutory financial information filed by such subsidiaries with such Insurance Departments; certain other communications from the Company and Berkshire to their respective shareholders; and certain internal financial analyses and forecasts for the Company prepared by its management. We also have held discussions with members of the senior management of the Company and Berkshire regarding the strategic, financial and operating rationale for, and expected benefits of, the transactions contemplated by the Agreement and the past and current business operations, financial condition and future prospects of their respective companies. In addition, we have reviewed the reported price and trading activity for shares of Company Common Stock and shares of Berkshire Common Stock, compared certain financial and stock market information for the Company and Berkshire with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the reinsurance industry specifically and in other industries generally and performed such other studies and analyses as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial and other information reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. We are not actuaries and our services did not include actuarial determinations or evaluations by us or an attempt to evaluate actuarial assumptions. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including the loss and loss adjustment expense reserves) of the Company or Berkshire or any of their subsidiaries and we have not been furnished with any such evaluation or appraisal. In that regard, we have made no analyses of, and express no opinion as to, the adequacy of the loss and loss adjustment expense reserves of the Company or Berkshire. We were advised by the management of Berkshire that Berkshire does not prepare financial forecasts. Our review of Berkshire was limited to publicly available information and discussions with the management of Berkshire. We were not requested to, and did not, solicit from third parties indications of interest in acquiring all or part of the Company or in engaging in a business combination or any other strategic transaction with the Company.

Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the transactions contemplated by the Agreement and such opinion does not constitute a recommendation as to how any holder of shares of Company Common Stock should vote with respect to such transactions. In addition, we have not been requested

Annex IV-2


to make, and we are not making, a recommendation as to whether any holder of Company Common Stock who is entitled to make a Class A Election should make such a Class A Election. We note that it is expected that the Company Merger Transaction will be tax-free to the holders of Company Common Stock but that, in the event that the Alternative Company Merger Transaction occurs, holders of Company Common Stock will recognize gain or loss for federal income tax purposes. In rendering this opinion, we have not taken into account the particular tax consequences of the Company Merger Transaction or the Alternative Company Merger Transaction to the holders of Company Common Stock. Our opinion is necessarily based upon financial, economic, market and other conditions as they exist and can be evaluated on the date hereof.

Based upon and subject to the foregoing and based upon such other matters as we consider relevant, it is our opinion that, as of the date hereof, the Merger Consideration to be received in the Transactions by holders of shares of Company Common Stock pursuant to the Agreement is fair from a financial point of view to such holders.

Very truly yours,

GOLDMAN, SACHS & CO.

ANNEX IX

SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW

(S) 262. APPRAISAL RIGHTS.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to (S) 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to (S) 251 (other than a merger effected pursuant to (S) 251(g) of this title), (S) 252, (S) 254, (S) 257, (S) 258, (S) 263 or (S) 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation

as provided in subsection (f) of (S) 251 of this title.

  (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series
of stock of a constituent corporation if the holders thereof are required
by the terms of an agreement of merger or consolidation pursuant to
(S)(S) 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under (S) 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

Annex IX-1


(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of his shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of his shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of his shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to (S) 228 or (S) 253 of this title, each consitutent corporation, either before the effective date of the merger or consolidation or within ten days thereafter, shall notify each of the holders of any class or series of stock of such constitutent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section; provided that, if the notice is given on or after the effective date of the merger or consolidation, such notice shall be given by the surviving or resulting corporation to all such holders of any class or series of stock of a constituent corporation that are entitled to appraisal rights. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either
(i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constitutent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constitutent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which notice is given.

Annex IX-2


(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw his demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after his written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted his certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that he is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of

Annex IX-3


Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who had demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of his demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

Annex IX-4

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 145 of the General Corporation Law of Delaware empowers the Registrants to indemnify, subject to the standards therein prescribed, any person in connection with any action, suit or proceeding brought or threatened by reason of the fact that such person is or was a director, officer, employee or agent of the Registrants or is or was serving as such with respect to another corporation or other entity at the request of the Registrants. Section 10 of the Registrants' By-Laws provides that such Registrant shall, to the fullest extent permitted by Section 145 of the General Corporation Law of Delaware, indemnify its directors and officers from and against any and all of the expenses, liabilities or other matters referred to in or covered by said Section. Additionally, as permitted by said Section and the Registrants' By- Laws, the Registrants have entered into indemnification agreements with each of its directors and officers. The description of the Berkshire Hathaway Inc. indemnification agreements under the caption "Summary of the Indemnification Agreements" on page 9 of Berkshire Hathaway Inc.'s definitive proxy statement for its May 19, 1987 Annual Meeting of Stockholders, Commission File No. 0-7413, is incorporated herein by reference. The NBH, Inc. indemnification agreements are substantially identical to those of Berkshire Hathaway Inc.

As permitted by Section 102 of the General Corporation Law of Delaware, the Registrants' Certificates of Incorporation includes a provision eliminating, to the extent permitted by Delaware law, the personal liability of each director of the Registrants to the Registrants or any of its stockholders for monetary damages resulting from breaches of such director's fiduciary duty of care.

ITEM 22. UNDERTAKINGS.

The undersigned Registrants hereby undertake:

(a) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) to include any prospectus required by section 10(a)(3) of the Securities Act of 1933 (the "Securities Act");

(ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post- effective amendment hereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement.

(b) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(d) to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(e) to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

(f) that, for purposes of determining any liability under the Securities Act of 1933, each filing of a Registrants' annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of any employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(g) insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrants pursuant to the foregoing provisions, or otherwise, the Registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by a Registrant of expenses incurred or paid by a director, officer or controlling person of such Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, a Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
