Agreement unless otherwise indicated. The terms defined in the singular have a comparable meaning when used

in the plural, and vice versa. References to “herein”, “hereof”, “hereunder” and the like refer to this Agreement

as a whole and not to any particular section or provision, unless the context requires otherwise. The table of

Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be

deemed followed by the words “without limitation.” No rule of construction against the draftsperson shall be

applied in connection with the interpretation or enforcement of this Agreement, as this Agreement is the product

of negotiation between sophisticated parties advised by counsel. All references to “$” or “dollars” mean the

lawful currency of the United States of America. Except as expressly stated in this Agreement, all references to

any statute, rule or regulation are to the statute, rule or regulation as amended, modified, supplemented or

replaced from time to time (and, in the case of statutes, include any rules and regulations promulgated under the

statute) and to any section of any statute, rule or regulation include any successor to the section. References to a

“business day” shall mean a business day in the City of New York.

Section 1.4.

No Reliance. Each party acknowledges that it is not relying upon any

representation or warranty not set forth in the Transaction Documents. The Investor acknowledges that it has

had an opportunity to conduct such review and analysis of the business, assets, condition, operations and

prospects of the Company and its subsidiaries, including an opportunity to ask such questions of management

(for which it has received such answers) and to review such information maintained by the Company, in each

case as the Investor considers sufficient for the purpose of making the Purchase. The Investor further

acknowledges that it has had such an opportunity to consult with its own counsel, financial and tax advisers and

other professional advisers as it believes is sufficient for purposes of the Purchase. For purposes of this

Agreement, the term “Transaction Documents” refers collectively to this Agreement, the Warrant and the

Registration Rights Agreement, in each case, as amended, modified or supplemented from time to time in

accordance with their respective terms.

similar laws affecting the enforcement of creditors’ rights generally and general equitable principles, regardless

of whether such enforceability is considered in a proceeding at law or in equity (“Bankruptcy Exceptions”).

(ii)

The execution, delivery and performance by the Company of this Agreement and

the other Transaction Documents and the consummation of the transactions contemplated hereby and thereby

and compliance by the Company with any of the provisions hereof and thereof, will not (i) violate, conflict with,

or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time

or both, would constitute a default) under, or result in the termination of, or accelerate the performance required

by, or result in a right of termination or acceleration of, or result in the creation of, any lien, security interest,

Adverse Effect.

capital stock or (I) any failure to meet any internal or public projections, forecasts, guidance, estimates,

milestones, or budgets or internal or published financial or operating predictions of revenue, earnings, cash flow

or cash position (it being understood that the exceptions in clauses (H) and (I) shall not prevent or otherwise

affect a determination that the underlying cause of any such change, decline or failure referred to therein (if not

provided

that, in the case of clauses (A), (B), (C) and (D), to the extent the impact on the Company and its subsidiaries,

Section 2.3.

Representations and Warranties of the Investor. The Investor, hereby represents

and warrants to the Company that as of the date hereof and the Closing Date:

(a)

Status. The Investor has been duly organized and is validly existing as a corporation

under the laws of Delaware.

(b)

Authorization, Enforceability.

(i)

The Investor has the power and authority, corporate or otherwise, to execute and

deliver this Agreement and the Registration Rights Agreement and to carry out its obligations hereunder and

thereunder. The execution, delivery and performance by the Investor of this Agreement and the Registration

Rights Agreement and the consummation of the transactions contemplated hereby and thereby have been duly

authorized by all necessary action on the part of the Investor, and no further approval or authorization is

required on the part of the Investor or any other party for such authorization to be effective. This Agreement and

the Registration Rights Agreement are or will be valid and binding obligations of the Investor enforceable

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 7

against the Investor in accordance with their respective terms, except as the same may be limited by Bankruptcy

Exceptions.

(ii)

The execution, delivery and performance by the Investor of this Agreement and

the Registration Rights Agreement and the consummation of the transactions contemplated hereby and thereby

and compliance by the Investor with any of the provisions hereof and thereof, will not (i) violate, conflict with,

or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time

or both, would constitute a default) under, or result in the termination of, or accelerate the performance required

by, or result in a right of termination or acceleration of, or result in the creation of, any lien, security interest,

charge or encumbrance upon any of the properties or assets of the Investor under any of the terms, conditions or

provisions of (A) its organizational documents or (B) any note, bond, mortgage, indenture, deed of trust, license,

lease, agreement or other instrument or obligation to which the Investor is a party or by which it may be bound,

or to which the Investor or any of the properties or assets of the Investor may be subject, or (ii) subject to

compliance with the statutes and regulations referred to in the next paragraph, violate any statute, rule or

regulation or any judgment, ruling, order, writ, injunction or decree applicable to the Investor or any of its

properties or assets except, in the case of clauses (i) (B) and (ii), for those occurrences that, individually or in the

aggregate, have not had and would not be reasonably likely to have an Investor Material Adverse Effect.

“Investor Material Adverse Effect” means a material adverse effect on the ability of the Investor to consummate

the Purchase and the other transactions contemplated by this Agreement.

(iii)

Other than such as have been made or obtained, no notice to, filing with,

exemption or review by, or authorization, consent or approval of, any Governmental Entity is required to be

made or obtained by the Investor in connection with the consummation by the Investor of the Purchase except

for any such notices, filings, exemptions, reviews, authorizations, consent and approvals the failure of which to

make or obtain would not be reasonably likely to have an Investor Material Adverse Effect.

(c)

Ownership. Without giving effect to the Purchase, the Investor is not the Beneficial

Owner of (i) any Common Stock or (ii) any securities or other instruments representing the right to acquire

Common Stock. The Investor does not have a formal or informal agreement, arrangement or understanding with

any person (other than the Company) to acquire, dispose of or vote any securities of the Company. “Beneficial

Ownership” shall be determined in accordance with Rules 13d-3 and 13d-5 under the Securities Exchange Act

of 1934 (the “Exchange Act”), including the provision that any member of a “group” shall be deemed to have

Beneficial Ownership of all securities Beneficially Owned by other members of the group, and except that the

exclusion in Rule 13d-3(d)(1)(i) for rights to acquire securities that are not exercisable “within 60 days” shall

not apply. “Beneficial Owner” and “Beneficially Own” shall have conforming definitions. Unless specified

otherwise, all percentage calculations of Beneficial Ownership will be calculated by including securities that the

person (including any group of which such person is a member), but not any other person, has the right to

acquire in both the numerator and the denominator.

To the extent the Investor transfers its rights to one or more of its Permitted Transferees at or prior to

Closing, the representations and warranties in Sections 2.3(a) and (b) shall be deemed to also be made by the

Investor in respect of each such Permitted Transferee and the representation and warranty in Section 2.3(c) shall

be deemed to be made in respect of the Investor and such Permitted Transferees collectively.

Article III

COVENANTS

Section 3.1.

Commercially Reasonable Efforts. Subject to the terms and conditions of this

Agreement, each of the parties will use its commercially reasonable efforts in good faith to take, or cause to be

taken, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 8

applicable laws, so as to permit consummation of the Purchase and the exercise in full of the Warrant for

Warrant Shares as promptly as practicable and otherwise to enable consummation of the transactions

contemplated hereby and by the other Transaction Documents (including making filings and deliveries) and

shall use commercially reasonable efforts to cooperate with the other party to that end. Without limiting the

generality of the foregoing, at the request of the Investor, the Company shall make or cause to be made all

filings required from the Company or its respective subsidiaries or affiliates under the Hart-Scott-Rodino

Antitrust Improvements Act of 1976 (the “HSR Act”) to permit the Investor to acquire all of the Warrant Shares

and shall use commercially reasonable efforts to cooperate with the Investor in connection with HSR Act filings

and otherwise with respect to the obtaining of any required antitrust approvals.

Section 3.2.

Expenses. Unless otherwise provided in any Transaction Document executed

by the Company and the Investor, each of the parties hereto will bear and pay all costs and expenses incurred by

it or on its behalf in connection with the transactions contemplated under the Transaction Documents, including

fees and expenses of its own financial or other consultants, investment bankers, accountants and counsel.

Section 3.3.

Stockholder Approvals; Sufficiency of Authorized Common Stock. At any

annual or special meeting of Company stockholders commencing with the first annual meeting following the

Closing until such approvals are obtained, the Company shall use its reasonable best efforts to obtain (i) the

NYSE Stockholder Approval from its stockholders (if required for the issuance of Warrant Shares by the

Company upon exercise of the Warrant) and (ii) the Charter Amendment Approval from its stockholders (if

required for the issuance of Warrant Shares by the Company upon exercise of the Warrant), and shall take all

corporate action necessary to obtain such approvals. Until the date on which the Warrant has been fully

exercised, the Company shall at all times have reserved for issuance, free of preemptive or similar rights, a

sufficient number of shares of authorized and unissued Warrant Shares to effectuate the exercise of the Warrant

(A) from and after the Closing, for the number of Warrant Shares for which NYSE Stockholder Approval and

Charter Amendment Approval is not required for the issuance thereof by the Company upon exercise of the

Warrant and (B) from and after receipt of the NYSE Stockholder Approval (if required for the issuance of

Warrant Shares by the Company upon exercise of the Warrant) and/or the Charter Amendment Approval (if

required for the issuance of Warrant Shares by the Company upon exercise of the Warrant), for the balance of

the Warrant Shares. The Company shall cause, at its expense, as soon as reasonably practicable (x) following

the Closing Date, the number of Warrant Shares for which NYSE Stockholder Approval and Charter

Amendment Approval is not required for the issuance thereof by the Company upon exercise of the Warrant and

(y) following receipt of NYSE Stockholder Approval (if required for the issuance of Warrant Shares by the

Company upon exercise of the Warrant) and/or Charter Amendment Approval (if required for the issuance of

Warrant Shares by the Company upon exercise of the Warrant), the balance of the Warrant Shares, to be listed

on the New York Stock Exchange (“NYSE”) at the time they become freely transferable in the public market

under the Securities Act, subject to official notice of issuance, and shall maintain such listing on the NYSE for

so long as any Common Stock is listed on the NYSE. Nothing in this Section 3.3 shall preclude the Company

from satisfying its obligations in respect of the exercise of the Warrant by delivery of shares of Common Stock

which are held in the treasury of the Company.

Section 3.4.

Certain Notifications Until Closing. From the date of this Agreement until the

Closing, each party shall promptly notify the other party of (i) any fact, event or circumstance of which it is

aware and which would be reasonably likely to cause any representation or warranty of such party contained in

this Agreement to be untrue or inaccurate in any material respect or to cause any covenant or agreement of such

party contained in this Agreement not to be complied with or satisfied in any material respect and (ii) any fact,

circumstance, event, change, occurrence, condition or development of which it is aware and which, individually

or in the aggregate, has had or would be reasonably likely to have a Material Adverse Effect or an Investor

Material Adverse Effect, as the case may be;

provided

however

that, delivery of any notice pursuant to this

Section 3.4 shall not limit or affect any rights of or remedies available to the other party.

Section 3.5.

Authorization of Preferred Shares. The Company shall, prior to the Closing,

duly and validly authorize the Preferred Shares.

Prior to the five year anniversary of the Closing Date, without the prior written consent

of the Company, the Investor and its Permitted Transferees shall not (i) directly or indirectly transfer, sell,

assign, pledge, convey, hypothecate or otherwise encumber or dispose of any of the Purchased Securities, or (ii)

lend, hypothecate or permit any custodian to lend or hypothecate any of the Purchased Securities or any

Common Stock,

provided

that, if at any time the Purchased Securities do not qualify as “admitted assets” that

are eligible to be reported in the Investor’s or Permitted Transferee’s annual statement under the insurance

regulations applicable to the Investor or a Permitted Transferee holding any Purchased Securities, the Company

will not unreasonably withhold its consent to a Transfer (as defined below) of the Purchased Securities owned

by the Investor or such Permitted Transferee, as applicable, to a third party (subject, in the case of a Transfer of

Preferred Shares, to such Transfer satisfying the conditions set forth in the first proviso of Section 4.3(e)). In the

case of any such Transfer of the Warrant, the Company will take such actions with respect to allowing

transferees of the Warrant to become parties to, and have rights under, the Registration Rights Agreement. Each

transaction referenced in clauses (i) and (ii) of this Section 4.3(a) is herein called a “Transfer”. Neither exercises

of the Warrant for Warrant Shares, nor delivery of Preferred Shares as payment of the exercise price of the

Warrant, in each case in accordance with the terms of the Warrant, shall be deemed Transfers.

(b)

The Investor and the Permitted Transferees (individually or collectively) may not

Transfer any Warrant Shares other than (i) in a transaction that has been specifically approved by the Company

in writing, (ii) in a public offering registered with the Securities and Exchange Commission in the manner and to

the extent contemplated by the Registration Rights Agreement or in a sale under Rule 144 under the Securities

Act, where the Company has been offered the opportunity to designate a sole underwriter, broker or market

maker, or (iii) in a private transaction or series of related transactions, and, in the case of (ii) or (iii), to the

knowledge of the Investor or Permitted Transferee (with no duty of inquiry), no purchaser or group of related

purchasers acquires Common Stock in such transaction or series of transactions that, when aggregated with

Common Stock already owned by such purchaser or group of related purchasers, represents more than 3.5% of

the Company’s outstanding Common Stock, and in any case consistent with applicable laws and regulations.

(c)

Notwithstanding the foregoing, Section 4.3(a) and (b) shall not prevent the Investor and

the Permitted Transferees from Transferring any or all of the Purchased Securities or Warrant Shares, at any

time, to any direct or indirect subsidiary of the Investor where the Investor beneficially owns at least 80% of the

equity interests (measured by both voting rights and value) of such subsidiary and such subsidiary is classified

as a domestic partnership or domestic corporation for U.S. federal income tax purposes (each, a “Permitted

Transferee”), but only if the Permitted Transferee agrees in writing for the benefit of the Company to be bound

by the terms of this Agreement (including these transfer restrictions);

provided

that, if the Investor ceases to

beneficially own at least 80% of the equity interests (measured by both voting rights and value) of such

Permitted Transferee, such Permitted Transferee shall be required to transfer such Purchased Securities or

Warrant Shares to the Investor or a Permitted Transferee (or in the case of the Warrant Shares, in accordance

with Section 4.3(b)) immediately;

provided further

that, no such Transfer shall relieve the Investor of its

obligations under this Agreement. The Investor shall cause each Permitted Transferee to comply with this

Agreement as applicable to it.

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 10

(d)

Without the prior written consent of the Company, the Investor and its Permitted

Transferees may not engage in any Hedging Transaction with respect to any of the Purchased Securities or

Warrant Shares (but, in the case of Warrant Shares actually issued upon exercise of the Warrant, only prior to

the later of (i) their issuance and (ii) the fifth anniversary of the Closing Date). “Hedging Transaction” means

any short sale (whether or not against the box) or any purchase, sale or grant of any right (including any put or

call option, swap or other derivative transaction whether settled in cash or securities) to obtain a “short” or “put

equivalent position” with respect to the Common Stock.

(e)

On and after the five year anniversary of the Closing Date, the Investor and its

Permitted Transferees may Transfer the Purchased Securities to any other person,

provided

that (i) the amount

transferred to the transferee is at least equal to the lesser of (x) an amount of Preferred Securities having an

aggregate liquidation value of at least $1,000,000,000 or (y) an amount of Purchased Securities equal to all of

the Purchased Securities then owned by Investor together with its Permitted Transferees, (ii) the transfer and

resulting ownership are consistent with law and regulation and (iii) the transferee agrees, on terms and in a form

reasonably satisfactory to the Company, that its transfers, if any, will be subject to this Section 4.3(e),

provided

further

that, in the case of transferees from the Investor or a Permitted Transferee pursuant to this Section 4.3(e),

and any subsequent transferees the minimum transfer amount in clause (i) above shall be the lesser of (x) an

amount of Purchased Securities having an aggregate liquidation value of at least $500,000,000 and (y) the

aggregate amount of Purchased Securities held by such transferee.

(f)

The Purchased Securities are, and the Warrant Shares will be when issued, restricted

securities under the Securities Act and may not be offered or sold except pursuant to an effective registration

statement or an available exemption from registration under the Securities Act. Accordingly, the Investor shall

not, directly or through others, offer or sell any Purchased Securities or any Warrant Shares except pursuant to a

registration statement or pursuant to Rule 144 or another exemption from registration under the Securities Act, if

available. Prior to any Transfer of Purchased Securities or Warrant Shares other than pursuant to an effective

registration statement, the Investor shall notify the Company of such Transfer and the Company may require the

Investor to provide, prior to such Transfer, such evidence that the Transfer will comply with the Securities Act

(including written representations and an opinion of counsel) as the Company may reasonably request. The

Company may impose stop-transfer instructions with respect to any securities that are to be transferred in

contravention of this Agreement.

Section 4.4.

Purchase for Investment. The Investor acknowledges that the Purchased

Securities and the Warrant Shares have not been registered under the Securities Act or under any state securities

laws. The Investor (i) is acquiring the Purchased Securities pursuant to an exemption from registration under the

Securities Act solely for investment with no present intention to distribute them to any person in violation of the

Securities Act or any applicable U.S. state securities laws, (ii) will not sell or otherwise dispose of any of the

Purchased Securities or the Warrant Shares, except in compliance with the registration requirements or

exemption provisions of the Securities Act and any applicable U.S. state securities laws, (iii) has such

knowledge and experience in financial and business matters and in investments of this type that it is capable of

evaluating the merits and risks of the Purchase and of making an informed investment decision, and has

conducted a review of the business and affairs of the Company that it considers sufficient and reasonable for

purposes of making the Purchase, (iv) is able to bear the economic risk of the Purchase and at the present time is

able to afford a complete loss of such investment and (iv) is an “accredited investor” (as that term is defined by

Rule 501 under the Securities Act).

Section 4.5.

Legend. The Investor agrees that all certificates or other instruments

representing Purchased Securities and the Warrant Shares will bear a legend substantially to the following

effect:

“THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER

THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND

MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 11

REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER SUCH ACT AND

APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM

REGISTRATION UNDER SUCH ACT OR SUCH LAWS. THIS INSTRUMENT IS ISSUED PURSUANT

TO AND SUBJECT TO THE RESTRICTIONS ON TRANSFER AND OTHER PROVISIONS OF A

SECURITIES PURCHASE AGREEMENT, DATED APRIL 30, 2019, BETWEEN THE ISSUER OF THESE

SECURITIES AND THE INVESTOR REFERRED TO THEREIN, A COPY OF WHICH IS ON FILE WITH

THE ISSUER. THE SECURITIES REPRESENTED BY THIS INSTRUMENT MAY NOT BE SOLD OR

OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE WITH SAID AGREEMENT. ANY SALE OR

OTHER TRANSFER NOT IN COMPLIANCE WITH SAID AGREEMENT WILL BE VOID.”

In the event that (i) any Purchased Securities or Warrant Shares become registered under the Securities Act or

(ii) Warrant Shares are eligible to be transferred without restriction in accordance with Rule 144 under the

Securities Act, the Company shall (subject to the receipt of any evidence required under Section 4.3(e)) issue

new certificates or other instruments representing such Purchased Securities or Warrant Shares, which shall not

contain such portion of the above legend that is no longer applicable;

provided

that, the Investor surrenders to

the Company the previously issued certificates or other instruments.

Section 4.6.

Information Rights. At the request of the Investor, from time to time upon

reasonable notice, and subject in the case of non-public information, to the receipt by the Company of

reasonable confidentiality undertakings from the Investor, the Company shall make the Chief Financial Officer

of the Company available to meet with the Investor for the purpose of discussing with the Investor the financial

condition, business and results of operations of the Company. This right is non-transferable and terminates on

the date that the Investor and its Permitted Transferees no longer collectively hold Preferred Stock with an

aggregate liquidation value of at least $1,000,000,000.

(c)

by the mutual written consent of the Investor and the Company.

Internal Revenue Code of 1986, as amended, and applicable U.S. Treasury Regulations promulgated thereunder

(including determining the applicability or non-applicability of such preferred stock OID rules to the Preferred

Shares and, if such rules are determined to apply, the appropriate period for accruing the amount covered by

such rules into income); and (ii) the proper allocation, for tax purposes, of the aggregate purchase price for the

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 18

Holders of Series A shall not be entitled to any dividends, whether payable in cash, securities or other

property, other than dividends (if any) declared and payable on the Series A as specified in this Section 4

(subject to the other provisions of this Certificate of Designations).

(b)

Priority of Dividends. So long as any share of Series A remains outstanding, no dividend shall

be declared or paid on the Common Stock or any other shares of Junior Stock (other than a dividend payable

solely in Junior Stock), and no Common Stock, Junior Stock or Parity Stock shall be purchased, redeemed or

otherwise acquired for consideration by the Corporation, directly or indirectly during a Dividend Period, unless

(x) all accrued and unpaid dividends for all past Dividend Periods, including the latest completed Dividend

Period (including, if applicable as provided in Section 4(a) above, dividends on such amount), on all outstanding

shares of Series A have been or are contemporaneously declared and paid in full (or declared and a sum

sufficient for the payment thereof has been set aside for the benefit of the holders of shares of Series A on the

applicable record date) and (y) the Corporation shall have paid or shall contemporaneously pay in full any

portion of the redemption price required to be paid by it pursuant to Section 6 that is unpaid at such time. The

foregoing provision shall not apply to redemptions, purchases or other acquisitions of shares of Common Stock

in connection with the cashless exercises and similar actions under any employee benefit plan in the ordinary

course of business and consistent with past practice prior to the Original Issuance Date.

When dividends are not paid (or declared and a sum sufficient for payment thereof set aside for the

benefit of the holders thereof on the applicable record date) on any Dividend Payment Date (or, in the case of

Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment

date falling within a Dividend Period related to such Dividend Payment Date) in full upon the Series A and any

shares of Parity Stock, all dividends declared on the Series A and all such Parity Stock and payable on such

Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the

Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such

Dividend Payment Date) shall be declared pro rata so that the respective amounts of such dividends declared

shall bear the same ratio to each other as all accrued and unpaid dividends per share on the Series A (including,

if applicable as provided in Section 4(a) above, dividends on such amount) and all Parity Stock payable on such

Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the

Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such

Dividend Payment Date) bear to each other.

Subject to the foregoing, such dividends (payable in cash, securities or other property) as may be

determined by the Board of Directors (or a duly authorized committee of the Board of Directors) may be

declared and paid on any securities of the Corporation (other than Series A), including Common Stock and other

Junior Stock, from time to time out of any funds legally available for such payment, and the Series A shall not

be entitled to participate in any such dividends.

Section 5.

Liquidation Rights.

receive for each share of Series A, out of the assets of the Corporation or proceeds thereof (whether capital or

surplus) available for distribution to stockholders of the Corporation, and after satisfaction of all liabilities and

obligations to creditors of the Corporation, before any distribution of such assets or proceeds is made to or set

aside for the holders of Common Stock and any other stock of the Corporation ranking junior to the Series A as

to such distribution, payment in full in an amount equal to the sum of (i) $105,000 per share and (ii) the accrued

and unpaid dividends thereon (including, if applicable as provided in Section 4(a) above, dividends on such

amount), whether or not declared, to the date of payment. Furthermore, without limiting in any way the

obligation of the Corporation to make the payments specified in the immediately preceding sentence, in

connection with the payment of the amounts specified in clause (ii) of the immediately preceding sentence, the

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 19

Corporation shall use its reasonable best efforts to ensure that, immediately prior to any such liquidation,

dissolution or winding up, the Corporation shall declare and pay any accrued and unpaid dividends (including, if

applicable as provided in Section 4(a) above, dividends on such amount) outstanding as of such time.

(b)

Partial Payment. If in any distribution described in Section 5(a) above the assets of the

Corporation or proceeds thereof are not sufficient to pay the Liquidation Preferences (as defined below) in full

to all holders of Series A and all holders of any stock of the Corporation ranking equally with the Series A as to

such distribution, the amounts paid to the holders of Series A and to the holders of all such other stock shall be

paid

pro rata

in accordance with the respective aggregate Liquidation Preferences of the holders of Series A and

the holders of all such other stock. In any such distribution, the “Liquidation Preference” of any holder of stock

of the Corporation shall mean the amount otherwise payable to such holder in such distribution (assuming no

limitation on the assets of the Corporation available for such distribution), including an amount equal to any

declared but unpaid dividends (and, in the case of any holder of stock, including the Series A, on which

applicable, dividends on such amount), whether or not declared, as applicable),

provided

that the Liquidation

Preference for any share of Series A shall be determined in accordance with Section 5(a) above.

(c)

A, the holders of other stock of the Corporation shall be entitled to receive all remaining assets of the

Corporation (or proceeds thereof) according to their respective rights and preferences.

consolidation in which the holders of Series A receive cash, securities or other property for their shares, or the

sale, lease or exchange (for cash, securities or other property) of all or substantially all of the assets of the

Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation.

last addresses appearing on the books of the Corporation. Such mailing shall be at least 30 days and not more

(e)

Partial Redemption. In case of any redemption of part of the shares of Series A at the time

outstanding, the shares to be redeemed shall be selected either

pro rata

or in such other manner as the

Corporation may determine to be fair and equitable. Subject to the provisions hereof, the Corporation shall have

full power and authority to prescribe the terms and conditions upon which shares of Series A shall be redeemed

from time to time. If fewer than all the shares represented by any certificate are redeemed, a new certificate

shall be issued representing the unredeemed shares without charge to the holder thereof.

(f)

Effectiveness of Redemption. If notice of redemption has been duly given and if on or before the

redemption date specified in the notice all funds necessary for the redemption have been deposited by the

trust company doing business in the Borough of Manhattan, The City of New York, and having a capital and

surplus of at least $50 million and selected by the Board of Directors, so as to be and continue to be available

solely therefor, then, notwithstanding that any certificate for any share so called for redemption has not been

surrendered for cancellation, on and after the redemption date dividends shall cease to accrue on all shares so

called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 22

the holders thereof to receive the amount payable on such redemption from such bank or trust company, without

interest. Any funds unclaimed at the end of three years from the redemption date shall, to the extent permitted

by law, be released to the Corporation, after which time the holders of the shares so called for redemption shall

look only to the Corporation for payment of the redemption price of such shares.

Section 7.

shares into any other securities, except in connection with the surrender to the Corporation of shares of the

of consummation of such exchange, reclassification, merger or consolidation (provided, that if pursuant

closing time of trading on a particular day is 4:00 p.m. and the specified event occurs at 5:00 p.m. on that day,

the Market Price would be determined by reference to such 4:00 p.m. closing price).

Warrant) and all applicable Regulatory Approvals, up to an aggregate of 80,000,000 fully paid and

to Section 13 hereof), at a purchase price per share of Common Stock equal to the Exercise Price,

provided

however

, after the receipt of the NYSE Stockholder Approval (if required for the issuance of Warrant Shares by

the Corporation upon exercise of the Warrant) and the Charter Amendment Approval (if required for the

issuance of Warrant Shares by the Corporation upon exercise of the Warrant), if the Warrantholder provides a

Common Stock in reliance upon an application exemption, including, without limitation, the exemption

provided in Section 802.9 or Section 802.64, of the rules promulgated under the HSR Act, the Warrantholder

Exercise of Warrant; Term.

(A)

Subject to Section 2, to the extent permitted by applicable laws and regulations, the right to

purchase the Shares represented by this Warrant is exercisable, in whole or in part by the Warrantholder, at any

time or from time to time after the execution and delivery of this Warrant by the Corporation on the date hereof,

but in no event later than 5:00 p.m., New York City time, on the Expiration Date, by (i) the surrender of this

Warrant and Notice of Exercise or Sale annexed hereto, duly completed and executed on behalf of the

Warrantholder, at the principal executive office of the Corporation located at 5 Greenway Plaza, Suite 110,

Houston, Texas 77046 (or such other office or agency of the Corporation in the United States as it may

designate by notice in writing to the Warrantholder at the address of the Warrantholder appearing on the books

of the Corporation), and (ii) payment of the Exercise Price for the Shares thereby purchased at the election of

the Warrantholder by (a) tendering in cash, by certified or cashier’s check payable to the order of the

Corporation, or by wire transfer of immediately available funds to an account designated by the Corporation

and/or (b) the surrender to the Corporation of shares of the Corporation’s Cumulative Perpetual Preferred Stock,

Series A (“Preferred Stock”), valued for purposes of payment of the Exercise Price at the per share sum of (x)

$100,000 per share of Preferred Stock and (y) the amount of any accrued and unpaid dividends on each of such

surrendered shares of Preferred Stock (including all past due dividends) with such accrual computed from the

last dividend payment date through the applicable exercise date of this Warrant.

(B)

(i) Notwithstanding anything in this Warrant to the contrary, if the NYSE Stockholder Approval

and/or the Charter Amendment Approval are required for the issuance of Warrant Shares by the Corporation

upon exercise of the Warrant, then unless and until such required approvals have been received, the

Warrantholder shall not be permitted to exercise this Warrant for Shares as set forth in this Section 3, but rather

in lieu thereof shall be permitted to sell this Warrant to the Corporation, in whole or in part, by the surrender of

this Warrant and Notice of Exercise or Sale annexed hereto as set forth in Section 3(A)(i) above, for a cash

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 29

purchase price equal to the Warrant Option Value (in the case of a sale of the entire Warrant) or for a cash

purchase price equal to a pro rata portion of Warrant Option Value based on the percentage of the Warrant being

sold (in the case of a partial sale of the Warrant), in each case as of the date the Warrantholder delivers to the

Corporation such Notice of Exercise or Sale, and any cash payment due from the Corporation pursuant to this

clause (i) shall be made by the Corporation not later than 30 days after the determination of Warrant Option

Value; provided, that the Warrantholder shall not be permitted to sell this Warrant to the Corporation as set forth

in this Section 3(B)(i), in whole or in part, prior to the 30th day following the first annual meeting of the

Corporation following the issuance of this Warrant.

(ii) Notwithstanding anything in this Warrant to the contrary, (a) the Warrantholder hereby acknowledges and

agrees that its exercise of this Warrant for Shares is subject to the condition that the Warrantholder will have

first received any applicable Regulatory Approvals, and (b) in the event that the Warrantholder is required to

receive any applicable Regulatory Approval in order to exercise this Warrant for Shares and to own such Shares

without the Warrantholder being in violation of applicable law, rule or regulation and such Regulatory Approval

cannot be obtained within 180 days after the filing of the applicable premerger notification and report forms by

the Warrantholder for any reason other than the failure of the Warrantholder to use its commercially reasonable

efforts to obtain such approval, then the Warrantholder shall be permitted, in lieu of exercising this Warrant for

Shares as set forth in this Section 3, to sell this Warrant to the Corporation, in whole or in part, by the surrender

of this Warrant and Notice of Exercise or Sale annexed hereto as set forth in Section 3(A)(i) above, for a cash

purchase price per Warrant Share underlying the portion of the Warrant being sold equal to the Market Price per

Warrant Share less the Exercise Price per Warrant Share as of the date the Warrantholder delivers to the

Corporation such Notice of Exercise or Sale, and any cash payment due from the Corporation pursuant to this

Section 3(b)(ii) shall be made by the Corporation not later than 30 days after the determination of Market Price

per Warrant Share. Notwithstanding the foregoing or any other provision of this Warrant or the Purchase

Agreement to the contrary, in no event shall the Warrantholder be required to agree to (and, for clarity, none of

the following shall be deemed to be commercially reasonable) (1) any prohibition of or limitation on the

ownership or operation by the Warrantholder, any of its Affiliates, or any of its or their respective subsidiaries,

of any portion of their respective businesses or assets, (2) divest, hold separate or otherwise dispose of any

portion of its, its Affiliates’, or any of its or their respective subsidiaries’ respective businesses or assets, (3) any

limitation on the ability of the Warrantholder, any of its Affiliates, or any of its or their respective subsidiaries,

as the case may be, to acquire or hold, or exercise full rights of ownership of, the Warrant, the Warrant Shares,

the Shares, or the Preferred Stock, or (4) any other limitation on the Warrantholder’s, any of its Affiliates’, or

any of its or their respective subsidiaries’ ability to effectively control their respective businesses or operations

or any assets thereof.

(C)

If the Warrantholder does not exercise this Warrant in its entirety or does not sell this Warrant in

its entirety, as the case may be, the Warrantholder will be entitled to receive from the Corporation within a

reasonable time, and in any event not exceeding three business days, a new warrant in substantially identical

form for the purchase of that number of Shares equal to the difference between the number of Shares subject to

this Warrant and the number of Shares as to which this Warrant is so exercised (in the case of a Warrant

exercise) or a new warrant representing the portion of the Warrant that was not sold (in the case of a Warrant

sale). Notwithstanding anything in this Warrant to the contrary, the Warrantholder hereby acknowledges and

agrees that its exercise of this Warrant for Shares is subject to the conditions that the NYSE Stockholder

Approval (if required for the issuance of Warrant Shares by the Corporation upon exercise of the Warrant) and

the Charter Amendment Approval (if required for the issuance of Warrant Shares by the Corporation upon

exercise of the Warrant) have been received

Issuance of Shares; Authorization; Listing. Certificates for Shares issued upon exercise of this

Warrant will be issued in such name or names as the Warrantholder may designate and will be delivered to such

named Person or Persons within a reasonable time, not to exceed three business days after the date on which this

Warrant has been duly exercised in accordance with the terms of this Warrant. The Corporation hereby

represents and warrants that any Shares issued upon the exercise of this Warrant in accordance with the

provisions of Section 3(A) will be duly and validly authorized and issued, fully paid and nonassessable and free

from all taxes, liens and charges (other than liens or charges created by the Warrantholder, except as otherwise

provided herein, income and franchise taxes incurred in connection with the exercise of the Warrant or taxes in

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 30

respect of any transfer occurring contemporaneously therewith). The Corporation agrees that the Shares so

issued will be deemed to have been issued to the Warrantholder as of the close of business on the date on which

this Warrant and payment of the Exercise Price are delivered to the Corporation in accordance with the terms of

this Warrant, notwithstanding that the stock transfer books of the Corporation may then be closed or certificates

representing such Shares may not be actually delivered on such date. Subject to receipt of the NYSE

Stockholder Approval (if required for the issuance of Warrant Shares by the Corporation upon exercise of the

Warrant) and the Charter Amendment Approval (if required for the issuance of Warrant Shares by the

Corporation upon exercise of the Warrant), (x) the Corporation shall at all times reserve and keep available, out

of its authorized but unissued Common Stock, solely for the purpose of providing for the exercise of this

Warrant, the aggregate number of shares of Common Stock as shall from time to time be sufficient to effect the

exercise of the rights under this Warrant, and (y) if at any time the number of authorized but unissued shares of

Common Stock shall not be sufficient for purposes of the exercise of this Warrant in accordance with its terms,

without limitation of such other remedies as may be available to the Warrantholder, the Corporation shall

immediately take all corporate action necessary to increase its authorized and unissued shares of Common Stock

to a number of shares as shall be sufficient for such purposes. The Corporation will (A) procure, at its sole

expense, the listing of the Shares issuable upon exercise of this Warrant, subject to issuance or notice of

issuance, on all principal stock exchanges on which the Common Stock is then listed or traded and (B) maintain

such listings of such Shares at all times after issuance. The Corporation will use reasonable best efforts to

ensure that the Shares may be issued without violation of any applicable law or regulation or of any requirement

of any securities exchange on which the Shares are listed or traded. The Corporation and the Warrantholder will

reasonably cooperate to take such other actions as are necessary to obtain (i) any Regulatory Approvals

applicable to Warrantholder’s exercise of its rights hereunder, including with respect to the issuance or

acquisition of the Shares and (ii) any regulatory approvals applicable to the Corporation solely as a result of the

issuance of the Shares. Before taking any action that would cause an adjustment pursuant to Section 13 to

reduce the Exercise Price below the then par value (if any) of the Common Stock, the Corporation shall take any

and all corporate action that may, in the opinion of its counsel, be necessary in order that the Corporation may

validly and legally issue fully paid and non-assessable shares of Common Stock at the Exercise Price as so

adjusted.

No Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall

be issued upon any exercise of this Warrant. In lieu of any fractional Share to which the Warrantholder would

otherwise be entitled, the Warrantholder shall be entitled to receive a cash payment equal to the Market Price of

the Common Stock on the last trading day preceding the date of exercise less the Exercise Price for such

fractional share.

No Rights as Stockholders; Transfer Books. This Warrant does not entitle the Warrantholder to

any voting rights or other rights as a stockholder of the Corporation prior to the date of exercise hereof. The

Corporation will at no time close its transfer books against transfer of this Warrant in any manner that interferes

with the timely exercise of this Warrant.

Charges, Taxes and Expenses. Issuance of certificates for Shares to the Warrantholder upon the

exercise of this Warrant shall be made without charge to the Warrantholder for any issue or transfer tax or other

incidental expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid

by the Corporation.

Transfer/Assignment.

the same tenor and date as this Warrant but registered in the name of one or more transferees, upon surrender of

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 31

this Warrant, duly endorsed, to the office or agency of the Corporation described in Section 3(A). All expenses

(other than stock transfer taxes) and other charges payable in connection with the preparation, execution and

delivery of the new warrants pursuant to this Section 8 shall be paid by the Corporation.

the Warrantholder to the Corporation, for a new warrant or warrants of like tenor and representing the right to

purchase the same aggregate number of Shares. The Corporation shall maintain a registry showing the name

and address of the Warrantholder as the registered holder of this Warrant. This Warrant may be surrendered for

exchange, exercise, or sale, in accordance with its terms, at the office of the Corporation, and the Corporation

shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.

10.

Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Corporation of evidence

reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any

such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the

Corporation, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the

Corporation shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant

of like tenor and representing the right to purchase the same aggregate number of Shares as provided for in such

lost, stolen, destroyed or mutilated Warrant.

11.

Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the

expiration of any right required or granted herein shall not be a business day, then such action may be taken or

such right may be exercised on the next succeeding day that is a business day.

12.

Rule 144 Information. The Corporation covenants that it will use its reasonable best efforts to

timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange

Act and the rules and regulations promulgated by the SEC thereunder (or, if the Corporation is not required to

file such reports, it will, upon the request of any Warrantholder, make publicly available such information as

necessary to permit sales pursuant to Rule 144 or Regulation S under the Securities Act), and it will use

reasonable best efforts to take such further action as any Warrantholder may reasonably request, in each case to

the extent required from time to time prior to the second anniversary of the Expiration Date to enable such

holder to, if permitted by the terms of this Warrant and the Purchase Agreement, sell this Warrant or any Shares

without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144

or Regulation S under the Securities Act, as such rules may be amended from time to time, or (B) any successor

rule or regulation hereafter adopted by the SEC. Upon the written request of any Warrantholder, the

Corporation will deliver to such Warrantholder a written statement that it has complied with such requirements.

13.

Adjustments and Other Rights. The Exercise Price and the number of Shares issuable upon

exercise of this Warrant shall be subject to adjustment from time to time as follows; provided, that if more than

one subsection of this Section 13 is applicable to a single event, the subsection shall be applied that produces the

largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section

13 so as to result in duplication:

(A)

Stock Splits, Subdivisions, Reclassifications or Combinations. If the Corporation shall (i) declare

and pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide or

reclassify the outstanding shares of Common Stock into a greater number of shares, or (iii) combine or

reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Shares

issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the

effective date of such subdivision, combination or reclassification shall be proportionately adjusted so that the

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 32

Warrantholder after such date shall be entitled to purchase the number of shares of Common Stock that such

holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this

Warrant after such date had this Warrant been exercised immediately prior to such date. In such event, the

Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of

such subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the

product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment and (2)

the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the

dividend, distribution, subdivision, combination or reclassification giving rise to this adjustment by (y) the new

number of Shares issuable upon exercise of the Warrant determined pursuant to the immediately preceding

sentence.

(B)

Certain Issuances of Common Shares or Convertible Securities. If the Corporation shall issue

shares of Common Stock (or rights or warrants or other securities exercisable or convertible into or

exchangeable (collectively, a “conversion”) for shares of Common Stock (collectively, “convertible securities”))

(other than in Permitted Transactions or a transaction to which subsection (A) of this Section 13 is applicable)

without consideration or at a consideration per share (or having a conversion price per share) that is less than

95% of the Market Price on the last trading day preceding the date of the agreement on pricing such shares (or

such convertible securities) then, in such event:

(i)

the number of Shares issuable upon the exercise of this Warrant immediately prior to the

date of the agreement on pricing of such shares (or of such convertible securities) (the “Initial

Number”) shall be increased to the number obtained by multiplying the Initial Number by a fraction (a)

the numerator of which shall be the sum of (x) the number of shares of Common Stock of the

Corporation outstanding on such date and (y) the number of additional shares of Common Stock issued

(or into which convertible securities may be exercised or convert) and (b) the denominator of which

shall be the sum of (x) the number of shares of Common Stock outstanding on such date and (y) the

number of shares of Common Stock that the aggregate consideration receivable by the Corporation for

the total number of shares of Common Stock so issued (or into which convertible securities may be

exercised or convert) would purchase at the Market Price on the last trading day preceding the date of

the agreement on pricing such shares (or such convertible securities); and

(ii)

the Exercise Price payable upon exercise of the Warrant shall be adjusted by multiplying

such Exercise Price in effect immediately prior to the date of the agreement on pricing of such shares

(or of such convertible securities) by a fraction, the numerator of which shall be the number of shares

of Common Stock issuable upon exercise of this Warrant prior to such date and the denominator of

which shall be the number of shares of Common Stock issuable upon exercise of this Warrant

immediately after the adjustment described in clause (B)(i) above.

For purposes of the foregoing, the aggregate consideration receivable by the Corporation in connection

with the issuance of such shares of Common Stock or convertible securities shall be deemed to be equal to the

sum of the net offering price (after deduction of any related expenses payable to third parties) of all such

securities plus the minimum aggregate amount, if any, payable upon exercise or conversion of any such

convertible securities into shares of Common Stock; and “Permitted Transactions” shall include issuances (1) as

consideration for or to fund the acquisition by the Corporation of businesses and/or assets constituting a

significant part of a business (including, without limitation, the Acquisition), (2) in connection with employee

benefit plans and compensation related arrangements of the Corporation approved by the Board of Directors,

and (3) in connection with a broadly marketed offering and sale of Common Stock or convertible securities for

cash conducted by the Corporation on a basis consistent with large public companies similar to the Corporation

in their own capital raising transactions. Any adjustment made pursuant to this Section 13(B) shall become

effective immediately upon the date of such issuance.

(C)

Other Distributions. In case the Corporation shall fix a record date for the making of a

distribution to all holders of shares of its Common Stock of securities, evidences of indebtedness, assets, cash,

rights or warrants (excluding (x) Ordinary Cash Dividends and (y) dividends of its Common Stock and other

dividends or distributions referred to in Section 13(A)), in each such case, the Exercise Price in effect prior to

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 33

such record date shall be reduced immediately thereafter to the price determined by multiplying the Exercise

Price in effect immediately prior to the reduction by the quotient of (i) the Market Price of the Common Stock

on the last trading day preceding the first date on which the Common Stock trades regular way on the New York

Stock Exchange without the right to receive such distribution, minus the amount of cash or the Fair Market

Value of the securities, evidences of indebtedness, assets, rights or warrants to be so distributed in respect of one

share of Common Stock (the “Per Share Fair Market Value”) divided by (ii) such Market Price on such date

specified in clause (i); such adjustment shall be made successively whenever such a record date is fixed. In such

event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number obtained

by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such

adjustment, and (2) the Exercise Price in effect immediately prior to the distribution giving rise to this

adjustment by (y) the new Exercise Price determined in accordance with the immediately preceding

sentence. In the case of adjustment for a cash dividend that is, or is coincident with, a regular quarterly

dividend, the Per Share Fair Market Value shall be reduced by the per share amount of the portion of the cash

dividend that would constitute an Ordinary Cash Dividend. In the event that such distribution is not so made,

the Exercise Price and the number of Shares issuable upon exercise of this Warrant then in effect shall be

readjusted, effective as of the date when the Board of Directors determines not to distribute such shares,

evidences of indebtedness, assets, rights, cash or warrants, as the case may be, to the Exercise Price that would

then be in effect and the number of Shares that would then be issuable upon exercise of this Warrant if such

record date had not been fixed.

(D)

Certain Repurchases of Common Stock. In case the Corporation effects a Pro Rata Repurchase

of Common Stock, then the Exercise Price shall be adjusted to the price determined by multiplying the Exercise

Price in effect immediately prior to the effective date of such Pro Rata Repurchase by a fraction of which the

numerator shall be (i) the product of (x) the number of shares of Common Stock outstanding immediately before

such Pro Rata Repurchase and (y) the Market Price of a share of Common Stock on the trading day immediately

preceding the first public announcement by the Corporation or any of its Affiliates of the intent to effect such

Pro Rata Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase, and of which the

denominator shall be the product of (x) the number of shares of Common Stock outstanding immediately prior

to such Pro Rata Repurchase minus the number of shares of Common Stock so repurchased and (y) the Market

Price per share of Common Stock on the trading day immediately preceding the first public announcement by

the Corporation or any of its Affiliates of the intent to effect such Pro Rata Repurchase. In such event, the

number of shares of Common Stock issuable upon the exercise of this Warrant shall be adjusted to the number

obtained by dividing (a) the product of (1) the number of Shares issuable upon the exercise of this Warrant

before such adjustment, and (2) the Exercise Price in effect immediately prior to the Pro Rata Repurchase giving

rise to this adjustment by (b) the new Exercise Price determined in accordance with the immediately preceding

sentence.

(E)

Business Combinations. In case of any Business Combination or reclassification of Common

Stock (other than a reclassification of Common Stock referred to in Section 13(A)), the Warrantholder’s right to

receive Shares upon exercise of this Warrant shall be converted into the right to exercise this Warrant to acquire

the number of shares of stock or other securities or property (including cash) that the Common Stock issuable

(at the time of such Business Combination or reclassification) upon exercise of this Warrant immediately prior

to such Business Combination or reclassification would have been entitled to receive upon consummation of

such Business Combination or reclassification; and in any such case, if necessary, the provisions set forth herein

with respect to the rights and interests thereafter of the Warrantholder shall be appropriately adjusted so as to be

applicable, as nearly as may reasonably be achievable, to the Warrantholder’s right to exercise this Warrant in

exchange for any shares of stock or other securities or property pursuant to this paragraph. In determining the

kind and amount of stock, securities or the property receivable upon exercise of this Warrant following the

consummation of such Business Combination, if the holders of Common Stock have the right to elect the kind

or amount of consideration receivable upon consummation of such Business Combination, then the

Warrantholder shall have the right to make a similar election (including, without limitation, being subject to

similar proration constraints) upon exercise of this Warrant with respect to the number of shares of stock or

other securities or property that the Warrantholder will receive upon exercise of this Warrant.

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 34

(F)

Rounding of Calculations; Minimum Adjustments. All calculations under this Section 13 shall

be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the

case may be. Any provision of this Section 13 to the contrary notwithstanding, no adjustment in the Exercise

Price or the number of Shares into which this Warrant is exercisable shall be made if the amount of such

adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, but any such amount

shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with

any subsequent adjustment that, together with such amount and any other amount or amounts so carried

forward, shall aggregate $0.01 or 1/10th of a share of Common Stock, or more.

(G)

Timing of Issuance of Additional Common Stock Upon Certain Adjustments. In any case in

which the provisions of this Section 13 shall require that an adjustment shall become effective immediately after

a record date for an event, the Corporation may defer until the occurrence of such event (i) issuing to the

Warrantholder of this Warrant exercised after such record date and before the occurrence of such event the

additional shares of Common Stock issuable upon such exercise by reason of the adjustment required by such

event over and above the shares of Common Stock issuable upon such exercise before giving effect to such

adjustment and (ii) paying to such Warrantholder any amount of cash in lieu of a fractional share of Common

Stock;

provided

however

, that the Corporation upon request shall deliver to such Warrantholder a due bill or

other appropriate instrument evidencing such Warrantholder’s right to receive such additional shares, and such

cash, upon the occurrence of the event requiring such adjustment.

(H)

Statement Regarding Adjustments. Whenever the Exercise Price or the number of Shares into

which this Warrant is exercisable shall be adjusted as provided in Section 13, the Corporation shall forthwith

file at the principal office of the Corporation a statement showing in reasonable detail the facts requiring such

adjustment and the Exercise Price that shall be in effect and the number of Shares into which this Warrant shall

be exercisable after such adjustment, and the Corporation shall also cause a copy of such statement to be sent by

a nationally recognized next day courier service (with a copy sent concurrently by e-mail) to each

Warrantholder at the mailing and e-mail addresses appearing in the Corporation’s records (which initially shall

be as set forth in Section 17 hereof).

(I)

Notice of Adjustment Event. In the event that the Corporation shall propose to take any action of

the type described in this Section 13 (but only if the action of the type described in this Section 13 would result

in an adjustment in the Exercise Price or the number of Shares into which this Warrant is exercisable or a

change in the type of securities or property to be delivered upon exercise of this Warrant), the Corporation shall

give notice to the Warrantholder, in the manner set forth in Section 13(H), which notice shall specify the record

date, if any, with respect to any such action and the approximate date on which such action is to take

place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate

the effect on the Exercise Price and the number, kind or class of shares or other securities or property that shall

be deliverable upon exercise of this Warrant. In the case of any action that would require the fixing of a record

date, such notice shall be given at least 10 days prior to the date so fixed, and in case of all other action, such

notice shall be given at least 15 days prior to the taking of such proposed action. Failure to give such notice, or

any defect therein, shall not affect the legality or validity of any such action.

(J)

Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking

of any action that would require an adjustment pursuant to this Section 13, the Corporation shall take any action

that may be necessary, including obtaining regulatory, New York Stock Exchange or stockholder approvals or

exemptions, in order that the Corporation may thereafter validly and legally issue as fully paid and

nonassessable all shares of Common Stock that the Warrantholder is entitled to receive upon exercise of this

Warrant pursuant to this Section 13.

(K)

Adjustment Rules. Any adjustments pursuant to this Section 13 shall be made successively

whenever an event referred to herein shall occur. If an adjustment in Exercise Price made hereunder would

reduce the Exercise Price to an amount below the par value of the Common Stock, then such adjustment in the

Exercise Price made hereunder shall reduce the Exercise Price to the par value of the Common Stock and then,

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 35

upon the Corporation’s satisfaction of its obligations under Section 4 hereof, to such lower par value as may

then be established.

14.

Governing Law.

This Warrant will be governed by and construed in accordance with the

laws of the State of New York applicable to contracts made and to be performed entirely within such

State. Each of the parties hereto agrees (a) to submit to the non-exclusive personal jurisdiction of the

Section 2.

Demand Registration.

Right to Request Registration. Subject to the provisions hereof, until the Termination

Date, the Investor may at any time request registration for resale under the Securities Act of all or part of the

Registrable Shares separate from an S-3 Shelf Registration (a “Demand Registration”);

provided

however

, that

(based on the then-current market prices) the number of Registrable Shares included in the Demand Registration

would, if fully sold, yield

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 42

gross proceeds to the Investor of at least the Minimum Amount. Subject to Section 2(d) and Sections 5 and 7

below, the Company shall use reasonable best efforts (i) to file a Registration Statement registering for resale

such number of Registrable Shares as requested to be so registered pursuant to this Section 2(a) (a “Demand

Registration Statement”) within 45 days after the Investor’s request therefor and (ii) if necessary, to cause such

Demand Registration Statement to be declared effective by the SEC as soon as practical thereafter. If permitted

under the Securities Act, such Registration Statement shall be one that is automatically effective upon filing.

(b)

Number of Demand Registrations. Subject to the limitations of Sections 2(a), 2(d) and

4(a), the Investor shall be entitled to request up to three Demand Registrations in the aggregate (regardless of the

number of Permitted Transferees who may become an Investor pursuant to Section 11). A Registration

Statement shall not count as a permitted Demand Registration unless and until it has become effective.

(c)

Priority on Demand Registrations. The Company may include Shares other than

Registrable Shares in a Demand Registration for any accounts (including for the account of the Company) on

the terms provided below; and if such Demand Registration is an underwritten offering, such Shares may be

included only with the consent of the managing underwriters of such offering. If the managing underwriters of

the requested Demand Registration advise the Company and the Investor requesting such Demand Registration

that in their opinion the number of Shares proposed to be included in the Demand Registration exceeds the

number of Shares which can be sold in such underwritten offering without materially delaying or jeopardizing

the success of the offering (including the price per share of the Shares proposed to be sold in such underwritten

offering), the Company shall include in such Demand Registration (i) first, the number of Registrable Shares

that the Investor proposes to sell, and (ii) second, the number of Shares proposed to be included therein by any

other Persons (including Shares to be sold for the account of the Company) allocated among such Persons in

such manner as the Company may determine. If the number of Shares which can be sold is less than the number

of Shares proposed to be registered pursuant to clause (i) above by the Investor, the amount of Shares to be sold

shall be allocated to the Investor.

(d)

Restrictions on Demand Registrations. The Investor shall not be entitled to request a

Demand Registration (i) within six months after the Investor has sold Shares in a Demand Registration or an

underwritten Shelf Takedown requested pursuant to Section 4(b) or (ii) at any time when the Company is

diligently pursuing a primary or secondary underwritten offering pursuant to a Piggyback Registration.

Notwithstanding the foregoing, the Company shall not be obligated to proceed with a Demand Registration if

the offering to be effected pursuant to such registration can be effected pursuant to an S-3 Shelf Registration and

the Company, in accordance with Section 4, effects or has effected an S-3 Shelf Registration pursuant to which

such offering can be effected.

(e)

Underwritten Offerings. The Investor shall be entitled to request an underwritten

offering pursuant to a Demand Registration, but only if the number of Registrable Shares to be sold in the

offering would reasonably be expected to yield gross proceeds to the Investor of at least the Minimum Amount

(based on then-current market prices) and only if the request is not made within six months after the Investor has

sold Shares in an underwritten

offering pursuant to (i) a Demand Registration or (ii) an S-3 Shelf Registration. If any of the Registrable Shares

covered by a Demand Registration are to be sold in an underwritten offering, the Company shall have the right

to select the managing underwriter or underwriters to lead the offering.

(f)

Effective Period of Demand Registrations. Upon the date of effectiveness of any

Demand Registration for an underwritten offering and if such offering is priced promptly on or after such date,

the Company shall use reasonable best efforts to keep such Demand Registration Statement effective for a

period equal to 60 days from such date or such shorter period which shall terminate when all of the Registrable

Shares covered by such Demand Registration have been sold by the Investor. If the Company shall withdraw

any Demand Registration pursuant to Section 5 before such 60 days end and before all of the Registrable Shares

covered by such Demand Registration have been sold pursuant thereto, the Investor shall be entitled to a

replacement Demand Registration which shall be subject to all of the provisions of this Agreement. A Demand

Registration shall not count against the limit on the number of such registrations set forth in Section 2(b) if (i)

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 43

after the applicable Registration Statement has become effective, such Registration Statement or the related

offer, sale or distribution of Registrable Shares thereunder becomes the subject of any stop order, injunction or

other order or restriction imposed by the SEC or any other governmental agency or court for any reason not

attributable to the Investor or its Affiliates (other than the Company and its controlled Affiliates) and such

interference is not thereafter eliminated so as to permit the completion of the contemplated distribution of

Registrable Shares or (ii) in the case of an underwritten offering, the conditions specified in the related

underwriting agreement, if any, are not satisfied or waived for any reason not attributable to the Investor or its

Affiliates (other than the Company and its controlled Affiliates), and as a result of any such circumstances

described in clause (i) or (ii), less than 75% of the Registrable Shares covered by the Registration Statement are

sold by the Investor pursuant to such Registration Statement.

Section 3.

Piggyback Registrations.

(a)

Right to Piggyback.

Whenever prior to the Termination Date the Company proposes to register any Shares under

the Securities Act (other than on a registration statement on Form S-8, F-8, S-4 or F-4), whether for its own

account or for the account of one or more holders of Shares (other than the Investor), and the form of

registration statement to be used may be used for any registration of Registrable Shares (a “Piggyback

Registration”), the Company shall give written notice to the Investor of its intention to effect such a registration

and, subject to Sections 3(b) and 3(c), shall include in such registration statement and in any offering of Shares

to be made pursuant to that registration statement all Registrable Shares with respect to which the Company has

received a written request for inclusion therein from the Investor within 10 days after the Investor’s receipt of

the Company’s notice or, in the case of a primary offering, such shorter time as is reasonably specified by the

Company in light of the circumstances (

provided

that only Registrable Shares of the same class or classes as the

Shares being registered may be included). The Company shall have no obligation to proceed with any

Piggyback Registration and may abandon, terminate and/or withdraw such registration for any reason at any

time prior to the pricing thereof. If the Company or any other Person other than the Investor proposes to sell

Shares in an underwritten

offering pursuant to a registration statement on Form S-3 under the Securities Act, such offering shall be treated

as a primary or secondary underwritten offering pursuant to a Piggyback Registration.

(b)

Priority on Primary Piggyback Registrations. If a Piggyback Registration is initiated as

a primary underwritten offering on behalf of the Company and the managing underwriters advise the Company

and the Investor (if the Investor has elected to include Registrable Shares in such Piggyback Registration) that in

their opinion the number of Shares proposed to be included in such offering exceeds the number of Shares (of

any class) which can be sold in such offering without materially delaying or jeopardizing the success of the

offering (including the price per share of the Shares proposed to be sold in such offering), the Company shall

include in such registration and offering (i) first, the number of Shares that the Company proposes to sell, and

(ii) second, the number of Shares requested to be included therein by holders of Shares, including the Investor

(if the Investor has elected to include Registrable Shares in such Piggyback Registration), pro rata among all

such holders on the basis of the number of Shares requested to be included therein by all such holders or as such

holders and the Company may otherwise agree (with allocations among different classes of Shares, if more than

one are involved, to be determined by the Company).

(c)

Priority on Secondary Piggyback Registrations. If a Piggyback Registration is initiated

as an underwritten registration on behalf of a holder of Shares other than the Investor, and the managing

underwriters advise the Company that in their opinion the number of Shares proposed to be included in such

registration exceeds the number of Shares (of any class) which can be sold in such offering without materially

delaying or jeopardizing the success of the offering (including the price per share of the Shares to be sold in

such offering), then the Company shall include in such registration (i) first, the number of Shares requested to be

included therein by the holder(s) requesting such registration, (ii) second, the number of Shares requested to be

included therein by other holders of Shares including the Investor (if the Investor has elected to include

Registrable Shares in such Piggyback Registration) and (iii) third, the number of Shares that the Company

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 44

proposes to sell, pro rata among such holders on the basis of the number of Shares requested to be included

therein by such holders or as such holders and the Company may otherwise agree (with allocations among

different classes of Shares, if more than one are involved, to be determined by the Company).

(d)

Selection of Underwriters. If any Piggyback Registration is a primary or secondary

underwritten offering, the Company shall have the right to select the managing underwriter or underwriters to

administer any such offering.

(e)

Basis of Participations. The Investor may not sell Registrable Shares in any offering

pursuant to a Piggyback Registration unless it (a) agrees to sell such Shares on the same basis provided in the

underwriting or other distribution arrangements approved by the Company and that apply to the Company

and/or any other holders involved in such Piggyback Registration and (b) completes and executes all

questionnaires, powers of attorney, indemnities, underwriting agreements, lockups and other documents

required under the terms of such arrangements.

Section 4.

S-3 Shelf Registration.

(a)

Right to Request Registration. Subject to the provisions hereof, at any time when the

Company is eligible to use Form S-3 prior to the Termination Date, the Investor shall be entitled to request on

one occasion that the Company file a Registration Statement on Form S-3 (or an amendment or supplement to

an existing registration statement on Form S-3) for a public offering of all or such portion of the Registrable

Shares designated by the Investor pursuant to Rule 415 promulgated under the Securities Act or otherwise (an

“S-3 Shelf Registration”). A request for an S-3 Shelf Registration may not be made within six months after the

Investor has sold Shares in a Demand Registration or at any time when an S-3 Shelf Registration is in effect or

the Company is diligently pursuing a primary or secondary underwritten offering pursuant to a registration

statement. Upon such request, and subject to Section 5, the Company shall use reasonable best efforts (i) to file

a Registration Statement (or any amendment or supplement thereto) covering the number of Registrable Shares

specified in such request under the Securities Act on Form S-3 (an “S-3 Shelf Registration Statement”) for

public sale in accordance with the method of disposition specified in such request within five business days (in

the case of a Registration Statement that is automatically effective upon filing) or 30 days (in the case of all

other Registration Statements) after the Investor’s written request therefor and (ii) if necessary, to cause such S-

3 Shelf Registration Statement to become effective as soon as practical thereafter. If permitted under the

Securities Act, such Registration Statement shall be one that is automatically effective upon filing. The right to

request an S-3 Shelf Registration may be exercised no more than once in the aggregate, regardless of the number

of Permitted Transferees who may become an Investor pursuant to Section 11. If the Investor has used its right

to an S-3 Shelf Registration pursuant to this Section 4 and has exercised fewer than three Demand Registrations,

the Investor may elect a second S-3 Shelf Registration and, upon such election, the number of Demand

Registrations available to the Investor shall be reduced by one.

(b)

Right to Effect Shelf Takedowns. The Investor shall be entitled, at any time and from

time to time when an S-3 Shelf Registration Statement is effective and until the Termination Date, to sell such

Registrable Shares as are then registered pursuant to such Registration Statement (each, a “Shelf Takedown”),

but only upon not less than three business days’ prior written notice to the Company (if such takedown is to be

underwritten). The Investor shall be entitled to request that a Shelf Takedown be an underwritten offering;

provided

however

, that (based on the then-current market prices) the number of Registrable Shares included in

each such underwritten Shelf Takedown would reasonably be expected to yield gross proceeds to the Investor of

at least the Minimum Amount, and

provided further

that the Investor shall not be entitled to request any

underwritten Shelf Takedown (i) within six months after the Investor has sold Shares in an underwritten offering

effected pursuant to (x) a Demand Registration or (y) an S-3 Shelf Registration or (ii) at any time when the

Company is diligently pursuing a primary or secondary underwritten offering of Shares pursuant to a

registration statement. The Investor shall give the Company prompt written notice of the consummation of each

Shelf Takedown (whether or not underwritten).

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 45

(c)

Priority on Underwritten Shelf Takedowns. The Company may include Shares other

than Registrable Shares in an underwritten Shelf Takedown for any accounts on the terms provided below, but

only with the consent of the managing underwriters of such offering

and the Investor (such consent not to be unreasonably withheld). If the managing underwriters of the requested

underwritten Shelf Takedown advise the Company and the Investor that in their opinion the number of Shares

proposed to be included in the underwritten Shelf Takedown exceeds the number of Shares which can be sold in

such offering without materially delaying or jeopardizing the success of the offering (including the price per

share of the Shares proposed to be sold in such offering), the Company shall include in such underwritten Shelf

Takedown (i) first, the number of Shares that the Investor proposes to sell, and (ii) second, the number of Shares

proposed to be included therein by any other Persons (including Shares to be sold for the account of the

Company) allocated among such Persons in such manner as the Company may determine. If the number of

Shares which can be sold is less than the number of Registrable Shares proposed to be included in the

underwritten Shelf Takedown pursuant to clause (i) above, the amount of Shares to be so sold shall be allocated

to the Investor. The provisions of this paragraph (c) apply only to a Shelf Takedown that the Investor has

requested be an underwritten offering.

(d)

Selection of Underwriters. If any of the Registrable Shares are to be sold in an

underwritten Shelf Takedown initiated by the Investor, the Company shall have the right to select the managing

underwriter or underwriters to lead the offering.

(e)

Effective Period of S-3 Shelf Registrations. The Company shall use reasonable best

efforts to keep any S-3 Shelf Registration Statement effective for a period of 90 days after the effective date of

such registration statement,

provided

that such 90 day period shall be extended by the number of days in any

Suspension Period commenced pursuant to Section 5 during such period (as it may be so extended) and by the

number of days in any Third Party Holdback Period commenced during such period (as it may be so extended).

Notwithstanding the foregoing, the Company shall not be obligated to keep any such registration statement

effective, or to permit Registrable Shares to be registered, offered or sold thereunder, at any time on or after the

Termination Date.

Section 5.

Suspension Periods.

(a)

Suspension Periods. The Company may (i) delay the filing or effectiveness of a

Registration Statement in conjunction with a Demand Registration or an S-3 Shelf Registration or (ii) prior to

the pricing of any underwritten offering or other offering of Registrable Shares pursuant to a Demand

Registration or an S-3 Shelf Registration, delay such underwritten or other offering (and, if it so chooses,

withdraw any registration statement that has been filed), but in each case described in clauses (i) and (ii) only if

the Company determines in its sole discretion (x) that proceeding with such an offering would require the

Company to disclose material information that would not otherwise be required to be disclosed at that time and

that the disclosure of such information at that time would not be in the Company’s best interests, or (y) that the

registration or offering to be delayed would, if not delayed, materially adversely affect the Company and its

subsidiaries taken as a whole or materially interfere with, or jeopardize the success of, any pending or proposed

material transaction, including any debt or equity financing, any acquisition or disposition, any recapitalization

or reorganization or any other material transaction, whether due to commercial reasons, a desire to avoid

premature disclosure of information or any other reason. Any period during which the Company has delayed a

filing, an effective date or an offering pursuant to this Section 5 is herein called a

“Suspension Period”. If pursuant to this Section 5 the Company delays or withdraws a Demand Registration or

S-3 Shelf Registration requested by the Investor, the Investor shall be entitled to withdraw such request and, if it

does so, such request shall not count against the limitation on the number of such registrations set forth in

Section 2 or 4. The Company shall provide prompt written notice to the Investor of the commencement and

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 46

termination of any Suspension Period (and any withdrawal of a registration statement pursuant to this Section

5), but shall not be obligated under this Agreement to disclose the reasons therefor. The Investor shall keep the

existence of each Suspension Period confidential and refrain from making offers and sales of Registrable Shares

(and direct any other Persons making such offers and sales to refrain from doing so) during each Suspension

Period. In no event (i) may the Company deliver notice of a Suspension Period to the Investor more than three

times in any calendar year and (ii) shall a Suspension Period or Suspension Periods be in effect for an aggregate

of 180 days or more in any calendar year.

(b)

Other Lockups. Notwithstanding any other provision of this Agreement, the Company

shall not be obligated to take any action hereunder that would violate any lockup or similar restriction binding

on the Company in connection with a prior or pending registration or underwritten offering.

(c)

Purchase Agreement Restrictions. Nothing in this Agreement shall affect the

restrictions on transfers of Shares and other provisions of the Purchase Agreement, which shall apply

independently hereof in accordance with the terms thereof.

Section 6.

Holdback Agreements.

The restrictions in this Section 6 shall apply for as long as the Investor is the beneficial owner

of any Registrable Shares. If the Company sells Shares or other securities convertible into or exchangeable for

(or otherwise representing a right to acquire) Shares in a primary underwritten offering pursuant to any

registration statement under the Securities Act (but only if the Investor is provided its piggyback rights, if any,

in accordance with Sections 3(a) and 3(b)), or if any other Person sells Shares in a secondary underwritten

offering pursuant to a Piggyback Registration in accordance with Sections 3(a) and 3(b), and if the managing

underwriters for such offering advise the Company (in which case the Company promptly shall notify the

Investor) that a public sale or distribution of Shares outside such offering would materially adversely affect such

offering, then, if requested by the Company, the Investor shall agree, as contemplated in this Section 6, not to

(and to cause its majority-controlled Affiliates not to) sell, transfer, pledge, issue, grant or otherwise dispose of,

directly or indirectly (including by means of any short sale), or request the registration of, any Registrable

Shares (or any securities of any Person that are convertible into or exchangeable for, or otherwise represent a

right to acquire, any Registrable Shares) for a period (each such period, a “Holdback Period”) beginning on the

10th day before the pricing date for the underwritten offering and extending through the earlier of (i) the 90th

day after such pricing date (subject to customary automatic extension in the event of the release of earnings

results of or material news relating to the Company) and (ii) such earlier day (if any) as may be designated for

this purpose by the managing underwriters for such offering (each such agreement of the Investor, a “Holdback

Agreement”). Each Holdback Agreement shall be in writing in form and substance satisfactory to the Company

and the managing underwriters. Notwithstanding the foregoing, the Investor shall not be obligated to

enter into a Holdback Agreement unless the Company and each selling shareholder in such offering also execute

agreements substantially similar to such Holdback Agreement. A Holdback Agreement shall not apply to (i) the

exercise of any warrants or options to purchase shares of the Company (

provided

that such restrictions shall

apply with respect to the securities issuable upon such exercise), (ii) any Shares included in the underwritten

offering giving rise to the application of this Section 6, or (iii) any Shares of the Company’s capital stock owned

or held by any employee benefit plan of the Investor or its majority-controlled Affiliates.

Section 7.

Registration Procedures.

(a)

Whenever the Investor requests that any Registrable Shares be registered pursuant to

this Agreement, the Company shall use reasonable best efforts to effect, as soon as practical as provided herein,

the registration and the sale of such Registrable Shares in accordance with the intended methods of disposition

thereof, and, pursuant thereto, the Company shall, as soon as practical as provided herein:

(i)

subject to the other provisions of this Agreement, use reasonable best efforts to prepare

and file with the SEC a Registration Statement with respect to such Registrable Shares and cause such

Registration Statement to become effective (unless it is automatically effective upon filing);

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 47

(ii)

use reasonable best efforts to prepare and file with the SEC such amendments and

supplements to such Registration Statement and the Prospectus used in connection therewith as may be

necessary to comply with the applicable requirements of the Securities Act and to keep such

Registration Statement effective for the relevant period required hereunder, but no longer than is

necessary to complete the distribution of the Registrable Shares covered by such Registration

Statement, and to comply with the applicable requirements of the Securities Act with respect to the

disposition of all the Registrable Shares covered by such Registration Statement during such period in

accordance with the intended methods of disposition set forth in such Registration Statement;

(iii)

use reasonable best efforts to obtain the withdrawal of any order suspending the

effectiveness of any Registration Statement, or the lifting of any suspension of the qualification or

exemption from qualification of any Registrable Shares for sale in any jurisdiction in the United States;

(iv)

deliver, without charge, such number of copies of the preliminary and final Prospectus

and any supplement thereto as the Investor may reasonably request in order to facilitate the disposition

of the Registrable Shares of the Investor covered by such Registration Statement in conformity with the

requirements of the Securities Act;

(v)

use reasonable best efforts to register or qualify such Registrable Shares under such

other securities or blue sky laws of such U.S. jurisdictions as the Investor reasonably requests and

continue such registration or qualification in effect in such jurisdictions for as long as the applicable

Registration Statement may be required to be kept effective under this Agreement (

provided

that the

Company will not be required to

qualify generally to do business in any jurisdiction where it would not otherwise be required to (I) qualify but

for this subparagraph (v), (II) subject itself to taxation in any such jurisdiction or (III) consent to general service

of process in any such jurisdiction);

(vi)

notify the Investor and each distributor of such Registrable Shares identified by the

Investor, at any time when a Prospectus relating thereto would be required under the Securities Act to

be delivered by such distributor, of the occurrence of any event as a result of which the Prospectus

included in such Registration Statement contains an untrue statement of a material fact or omits a

material fact necessary to make the statements therein, in light of the circumstances under which they

were made, not misleading, and, at the request of the Investor, the Company shall use reasonable best

efforts to prepare, as soon as practical, a supplement or amendment to such Prospectus so that, as

thereafter delivered to any prospective purchasers of such Registrable Shares, such Prospectus shall not

contain an untrue statement of a material fact or omit to state any material fact necessary to make the

statements therein, in light of the circumstances under which they were made, not misleading;

(vii)

in the case of an underwritten offering in which the Investor participates pursuant to a

Demand Registration, a Piggyback Registration or an S-3 Shelf Registration, enter into an underwriting

agreement in substantially the form used by the Company or companies of comparable market

capitalization for offerings of that kind, with appropriate modification, containing such provisions

(including provisions for indemnification, lockups, opinions of counsel and comfort letters), and take

all such other customary and reasonable actions as the managing underwriters of such offering may

request in order to facilitate the disposition of such Registrable Shares (including, making members of

senior management of the Company available at reasonable times and places to participate in “road-

shows” that the managing underwriter determines are necessary to effect the offering);

(viii)

in the case of an underwritten offering in which the Investor participates pursuant to a

Demand Registration, a Piggyback Registration or an S-3 Shelf Registration, and to the extent not

prohibited by applicable law, (A) make reasonably available, for inspection by the managing

underwriters of such offering and one attorney and accountant acting for such managing underwriters,

pertinent corporate documents and financial and other records of the Company and its subsidiaries and

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 48

controlled Affiliates, (B) cause the Company’s officers and employees to supply information

reasonably requested by such managing underwriters or attorney in connection with such offering, (C)

make the Company’s independent accountants available for any such managing underwriters’ due

diligence and have them provide customary comfort letters to such underwriters in connection

therewith; and (D) cause the Company’s counsel to furnish customary legal opinions to such

underwriters in connection therewith;

provided

however

, that such records and other information shall

be subject to such confidential treatment as is customary for underwriters’ due diligence reviews;

(ix)

use reasonable best efforts to cause all such Registrable Shares to be listed on each

primary securities exchange (if any) on which securities of the same class issued by the Company are

then listed;

(x)

provide a transfer agent and registrar for all such Registrable Shares not later than the

effective date of such Registration Statement and, a reasonable time before any proposed sale of

Registrable Shares pursuant to a Registration Statement, provide the transfer agent with printed

certificates for the Registrable Shares to be sold, subject to the provisions of Section 11;

(xi)

make generally available to its shareholders a consolidated earnings statement (which

need not be audited) for a period of 12 months beginning after the effective date of the Registration

Statement as soon as reasonably practicable after the end of such period, which earnings statement

shall satisfy the requirements of an earning statement under Section 11(a) of the Securities Act and

Rule 158 thereunder; and

(xii)

promptly notify the Investor and the managing underwriters of any underwritten

offering, if any:

(1)

when the Registration Statement, any pre-effective amendment, the Prospectus

or any Prospectus supplement or any post-effective amendment to the Registration Statement

has been filed and, with respect to the Registration Statement or any post-effective

amendment, when the same has become effective;

(2)

of any request by the SEC for amendments or supplements to the Registration

Statement or the Prospectus or for any additional information regarding the Investor;

(3)

of the notification to the Company by the SEC of its initiation of any

proceeding with respect to the issuance by the SEC of any stop order suspending the

effectiveness of the Registration Statement; and

(4)

of the receipt by the Company of any notification with respect to the

suspension of the qualification of any Registrable Shares for sale under the applicable

securities or blue sky laws of any jurisdiction.

For the avoidance of doubt, the provisions of clauses (vii), (viii), (xi) and (xii) of this Section

7(a) shall apply only in respect of an underwritten offering and only if (based on market prices at the time the

offering is requested by the Investor) the number of Registrable Shares to be sold in the offering would

reasonably be expected to yield gross proceeds to the Investor of at least the Minimum Amount.

(b)

No Registration Statement (including any amendments thereto) shall contain any untrue

statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the

statements therein not misleading, and no Prospectus (including any supplements thereto) shall contain any

untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in

light of the circumstances under which they were made, not misleading, in each case, except for any untrue

statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 49

in reliance on and in conformity with written information furnished to the Company by or on behalf of the

Investor, any selling securityholder or any underwriter or other distributor specifically for use therein.

(c)

At all times after the Company has filed a registration statement with the SEC pursuant

to the requirements of the Securities Act and until the Termination Date, the Company shall use reasonable best

efforts to continuously maintain in effect the registration of Common Stock under Section 12 of the Exchange

Act and to use reasonable best efforts to file all reports required to be filed by it under the Securities Act and the

Exchange Act and the rules and regulations adopted by the SEC thereunder, all to the extent required to enable

the Investor to be eligible to sell Registrable Shares (if any) pursuant to Rule 144 under the Securities Act.

(d)

The Company may require the Investor and each distributor of Registrable Shares as to

which any registration is being effected to furnish to the Company information regarding such Person and the

distribution of such securities as the Company may from time to time reasonably request in connection with

such registration.

(e)

The Investor agrees by having its shares of Common Stock treated as Registrable

Shares hereunder that, upon being advised in writing by the Company of the occurrence of an event pursuant to

Section 7(a)(vi), the Investor will immediately discontinue (and direct any other Persons making offers and sales

of Registrable Shares to immediately discontinue) offers and sales of Registrable Shares pursuant to any

Registration Statement (other than those pursuant to a plan that is in effect prior to such time and that complies

with Rule 10b5-1 under the Exchange Act) until it is advised in writing by the Company that the use of the

Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by

Section 7(a)(vi), and, if so directed by the Company, the Investor will deliver to the Company all copies, other

than permanent file copies then in the Investor’s possession, of the Prospectus covering such Registrable Shares

current at the time of receipt of such notice.

(f)

The Company may prepare and deliver a free writing prospectus (as such term is

defined in Rule 405 under the Securities Act) in lieu of any supplement to a Prospectus, and references herein to

any “supplement” to a Prospectus shall include any such free writing prospectus. Neither the Investor nor any

other seller of Registrable Shares may use a free writing prospectus to offer or sell any such shares without the

Company’s prior written consent.

(g)

It is understood and agreed that any failure of the Company to file a registration

statement or any amendment or supplement thereto or to cause any such document to become or remain

effective or usable within or for any particular period of time as provided in Section 2, 4 or 7 or otherwise in this

Agreement, due to reasons that are not reasonably within its control, or due to any refusal of the SEC to permit a

registration statement or prospectus to become or remain effective or to be used because of unresolved SEC

comments thereon (or on any documents incorporated therein by reference) despite the Company’s good faith

and reasonable best efforts to resolve those comments, shall not be a breach of this Agreement.

(h)

It is further understood and agreed that the Company shall not have any obligations

under this Section 7 at any time on or after the Termination Date, unless an underwritten offering in which the

Investor participates has been priced but not completed prior to the Termination Date, in which event the

Company’s obligations under this Section 7 shall continue with respect to such offering until it is so completed

(but not more than 60 days after the commencement of the offering).

(i)

Notwithstanding anything to the contrary in this Agreement, the Company shall not be

required to file a Registration Statement or include Registrable Shares in a Registration Statement unless it has

received from the Investor, at least five days prior to the anticipated filing date of the Registration Statement,

requested information required to be provided by the Investor for inclusion therein.

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 50

Section 8.

Registration Expenses.

(a)

All expenses incident to the Company’s performance of or compliance with this

Agreement, including all registration and filing fees, fees and expenses of compliance with securities or blue sky

laws, FINRA fees, listing application fees, printing expenses, transfer agent’s and registrar’s fees, cost of

distributing Prospectuses in preliminary and final form as well as any supplements thereto, and fees and

disbursements of counsel for the Company and all independent certified public accountants and other Persons

retained by the Company (all such expenses being herein called “Registration Expenses”) (but not including any

underwriting discounts or commissions attributable to the sale of Registrable Shares or fees and expenses of

counsel and any other advisor representing any underwriters or other distributors), shall be borne by the

Company. The Investor shall bear the cost of all underwriting discounts and commissions associated with any

sale of Registrable Shares and shall pay all of its own costs and expenses, including all fees and expenses of any

counsel (and any other advisers) representing the Investor and any stock transfer taxes.

(b)

The obligation of the Company to bear the expenses described in Section 8(a) shall

apply irrespective of whether a registration, once properly demanded or requested becomes effective or is

withdrawn or suspended;

provided

however

, that Registration Expenses for any Registration Statement

withdrawn solely at the request of the Investor (unless withdrawn following commencement of a Suspension

Period pursuant to Section 5) shall be borne by the Investor.

Section 9.

Indemnification.

(a)

The Company shall indemnify, to the fullest extent permitted by law, the Investor and

each Person who controls the Investor (within the meaning of the Securities Act) against all losses, claims,

damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including

reasonable attorneys’ fees) arising out of or based upon any untrue or alleged untrue statement of a material fact

contained in any Registration Statement or Prospectus or any amendment thereof or supplement thereto or

arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or

necessary to make the statements therein not misleading, except insofar as the same are made in reliance and in

conformity with information furnished in writing to the Company by the Investor expressly for use therein. In

connection with an underwritten offering in which the Investor participates conducted pursuant to a registration

effected hereunder, the Company shall indemnify each participating underwriter and each Person who controls

such underwriter (within the meaning of the Securities Act) to the same extent as provided above with respect to

the indemnification of the Investor.

(b)

In connection with any Registration Statement in which the Investor is participating, the

Investor shall furnish to the Company in writing such information as the Company reasonably requests for use

in connection with any such Registration Statement or Prospectus, or amendment or supplement thereto, and

shall indemnify, to the fullest extent permitted by law, (i) the Company, its officers and directors and each

Person who controls the Company (within the meaning of the Securities Act) and (ii) each participating

underwriter, if any, and each Person who controls such underwriter (within the meaning of the Securities Act)

against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and

expenses (including reasonable attorneys’ fees) arising out of or based upon any untrue or alleged untrue

statement of material fact contained in the Registration Statement or Prospectus, or any amendment or

supplement thereto, or arising out of or based upon any omission or alleged omission of a material fact required

to be stated therein or necessary to make the statements therein not misleading, but only to the extent that the

same are made in reliance and in conformity with information furnished in writing to the Company by or on

behalf of the Investor expressly for use therein.

(c)

Any Person entitled to indemnification hereunder shall (i) give prompt written notice to

the indemnifying Person of any claim with respect to which it seeks indemnification and (ii) permit such

indemnifying Person to assume the defense of such claim with counsel reasonably satisfactory to the

indemnified Person. Failure so to notify the indemnifying Person shall not relieve it from any liability that it

may have to an indemnified Person except to the extent that the indemnifying Person is materially and adversely

prejudiced thereby. The indemnifying Person shall not be subject to any liability for any settlement made by the

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 51

indemnified Person without its consent (but such consent will not be unreasonably withheld). An indemnifying

Person who is entitled to, and elects to, assume the defense of a claim shall not be obligated to pay the fees and

expenses of more than one counsel (in addition to one local counsel) for all Persons indemnified (hereunder or

otherwise) by such indemnifying Person with respect to such claim (and all other claims arising out of the same

circumstances), unless in the reasonable judgment of any indemnified Person there may be one or more legal or

equitable defenses available to such indemnified Person which are in addition to or may conflict with those

available to another indemnified Person with respect to such claim, in which case such maximum number of

counsel for all indemnified Persons shall be two rather than one). If an indemnifying Person is entitled to, and

elects to, assume the defense of a claim, the indemnified Person shall continue to be entitled to participate in the

defense thereof, with counsel of its own choice, but, except as set forth above, the indemnifying Person shall not

be obligated to reimburse the indemnified Person for the costs thereof. The indemnifying Person shall not

consent to the entry of any judgment or enter into or agree to any settlement relating to a claim or action for

which any indemnified Person would be entitled to indemnification by any indemnified Person hereunder unless

such judgment or settlement imposes no ongoing obligations on any such indemnified Person and includes as an

unconditional term the giving, by all relevant claimants and plaintiffs to such indemnified Person, a release,

satisfactory in form and substance to such indemnified Person, from all liabilities in respect of such claim or

action for which such indemnified Person would be entitled to such indemnification. The indemnifying Person

shall not be liable hereunder for any amount paid or payable or incurred pursuant to or in connection with any

judgment entered or settlement effected with the consent of an indemnified Person unless the indemnifying

Person has also consented to such judgment or settlement.

(d)

The indemnification provided for under this Agreement shall remain in full force and

effect regardless of any investigation made by or on behalf of the indemnified Person or any officer, director or

controlling Person of such indemnified Person and shall survive the transfer of securities and the Termination

Date but only with respect to offers and sales of Registrable Shares made before the Termination Date or during

the period following the Termination Date referred to in Section 7(h).

(e)

If the indemnification provided for in or pursuant to this Section 9 is due in accordance

with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims,

damages, liabilities or expenses referred to herein, then each applicable indemnifying Person, in lieu of

indemnifying such indemnified Person, shall contribute to the amount paid or payable by such indemnified

Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to

reflect the relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other

in connection with the statements or omissions which result in such losses, claims, damages, liabilities or

expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying Person on

the one hand and of the indemnified Person on the other shall be determined by reference to, among other

things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to

state a material fact relates to information supplied by the indemnifying Person or by the indemnified Person,

and by such Person’s relative intent, knowledge, access to information and opportunity to correct or prevent

such statement or omission. In no event shall the liability of the indemnifying Person be greater in amount than

the amount for which such indemnifying Person would have been obligated to pay by way of indemnification if

the indemnification provided for under Section 9(a) or 9(b) hereof had been available under the circumstances.

Section 10.

Securities Act Restrictions.

The Registrable Shares are restricted securities under the Securities Act and may not be

offered or sold except pursuant to an effective registration statement or an available exemption from registration

under the Securities Act. Accordingly, the Investor shall not, directly or through others, offer or sell any

Registrable Shares except pursuant to a Registration Statement as contemplated herein or pursuant to Rule 144

or another exemption from registration under the Securities Act, if available. Prior to any transfer of Registrable

Shares other than pursuant to an effective registration statement, the Investor shall notify the Company of such

transfer and the Company may require the Investor to provide, prior to such transfer, such evidence that the

transfer will comply with the Securities Act (including written representations or an opinion of counsel) as the

Company may reasonably request. The Company may impose stop-transfer instructions with respect to any

Berkshire Hathaway SECURITIES PURCHASE AGREEMENT — page 52

Registrable Shares that are to be transferred in contravention of this Agreement. Any certificates representing

the Registrable Shares may bear a legend (and the Company’s share registry may bear a notation) referencing

the restrictions on transfer contained in this Agreement (and the Purchase Agreement), until such time as such

securities have ceased to be (or are to be transferred in a manner that results in their ceasing to be) Registrable

Shares. Subject to the provisions of this Section 10, the Company will replace any such legended certificates

with unlegended certificates promptly upon surrender of the legended certificates to the Company or its

designee and cause shares that cease to be

Registrable Shares to bear a general unrestricted CUSIP number, in order to facilitate a lawful transfer or at any

time after such shares cease to be Registrable Shares.

Section 11.

Transfers of Rights.

(a)

If the Investor transfers any rights to a Permitted Transferee in accordance with the

Purchase Agreement, such Permitted Transferee shall, together with all other such Permitted Transferees and the

Investor, also have the rights of the Investor under this Agreement, but only if the Permitted Transferee signs

and delivers to the Company a written acknowledgment (in form and substance satisfactory to the Company)

that it has joined with the Investor and the other Permitted Transferees as a party to this Agreement and has

assumed the rights and obligations of the Investor hereunder with respect to the rights transferred to it by the

Investor. Each such transfer shall be effective when (but only when) the Permitted Transferee has signed and

delivered the written acknowledgment to the Company. Upon any such effective transfer, the Permitted

Transferee shall automatically have the rights so transferred, and the Investor’s obligations under this

Agreement, and the rights not so transferred, shall continue,

provided

that under no circumstances shall the

Company be required to provide (i) more than three Demand Registrations and (ii) more than one S-3 Shelf

Registration (or two in the event the Investor elects to exchange one of its Demand Registrations for an S-3

Shelf Registration). Notwithstanding any other provision of this Agreement, no Person who acquires securities

transferred in violation of this Agreement or the Purchase Agreement, or who acquires securities that are not or

upon acquisition cease to be Registrable Shares, shall have any rights under this Agreement with respect to such

securities, and such securities shall not have the benefits afforded hereunder to Registrable Shares.

Section 12.
