Each Selling Stockholder is selling the number of Firm Shares set forth opposite such Selling Stockholder's name in Schedule II hereto.

The Selling Stockholders also propose to sell to the several Underwriters not more than an additional 1,300,000 shares, in the aggregate, of the Class A common stock (the "Additional Shares") if requested by the Underwriters as provided in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter referred to collectively as the "Shares." The shares of Class A common stock of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the "Common Stock."

The registration statement, as amended at the time it became effective, including all financial schedules and exhibits thereto and documents incorporated therein by reference and including a registration statement (if any) filed pursuant to Rule 462(b) under the Act increasing the size of the offering registered under the Act and information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 434 under the Act, is hereinafter referred to as the "Registration Statement"; and the prospectus (including any prospectus subject to completion taken together with any term sheet meeting the requirements of Rule 434(b) or Rule 434(a) under the Act) in the form first used to confirm sales of the Shares is hereinafter referred to as the "Basic Prospectus," except that if any revised prospectus shall be provided to the Representatives by the Company for use in connection with the offering of the Shares as contemplated by Section 5 hereof which differs from the form of prospectus first used to confirm sales of the Shares, the term "Basic Prospectus" shall refer to such revised prospectus from and after the time it is first provided to the Representatives for such use. The Basic Prospectus, as supplemented by the prospectus supplement, dated [ ], 2003 (the "Prospectus Supplement"), relating to the Shares, in the form first used to confirm sales of the Shares, is hereinafter referred to as the "Prospectus."

SECTION 2. Agreements to Sell and Purchase and Lock-Up Agreements. On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, (i) each Selling Stockholder agrees, severally and not jointly, to sell the number of Firm Shares set forth opposite such Selling Stockholder's name in Schedule II hereto and (ii) each Underwriter agrees, severally and not jointly, to purchase from each Selling Stockholder, at a price per Share of $[ ] (the "Purchase Price"), the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Selling Stockholders, severally and not jointly, agree to sell the Additional Shares to the Underwriters, and the Underwriters shall have the right to purchase, severally and not jointly, up to 1,300,000 Additional Shares from the Selling Stockholders at the Purchase Price. Additional Shares may be purchased solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. The Underwriters may exercise their right to purchase Additional Shares in whole or in part from time to time by giving written notice thereof to the Selling Stockholders within 30 days after the date of this Agreement.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its directors, its officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action, that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto) or any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished in writing to the Company by such Underwriter through the Representatives expressly for use therein; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter who failed to deliver a Prospectus, as then amended or supplemented, (so long as the Prospectus and any amendment or supplement thereto was provided by the Company to the several Underwriters in the requisite quantity and on a timely basis to permit proper delivery on or prior to the Closing Date or the Option Closing Date, as the case may be) to the person asserting any losses, claims, damages, liabilities or judgments caused by any untrue statement or alleged untrue statement of a material fact contained in such preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such material misstatement or omission or alleged material misstatement or omission was cured in the Prospectus, as so amended or supplemented, and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person.

(b) Each of the Selling Stockholders agrees, severally and not jointly, to indemnify and hold harmless each Underwriter, its directors, its officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder expressly for use in the Registration Statement (or any amendment thereto),

the Prospectus (or any amendment or supplement thereto) or any preliminary prospectus. Notwithstanding the foregoing, the aggregate liability of any Selling Stockholder pursuant to the provisions of this paragraph shall be limited to an amount equal to the total proceeds (before deducting underwriting discounts and commissions and expenses) received by such Selling Stockholder from the Underwriters for the sale of the Shares sold by such Selling Stockholder hereunder; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter who failed to deliver a Prospectus, as then amended or supplemented, (so long as the Prospectus and any amendment or supplement thereto was provided by the Company to the several Underwriters in the requisite quantity and on a timely basis to permit proper delivery on or prior to the Closing Date or the Option Closing Date, as the case may be) to the person asserting any losses, claims, damages, liabilities or judgments caused by any untrue statement or alleged untrue statement of a material fact contained in such preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such material misstatement or omission or alleged material misstatement or omission was cured in the Prospectus, as so amended or supplemented, and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and any person controlling the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each Selling Stockholder and each person, if any, who controls such Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Underwriter furnished in writing by or on behalf of such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto) or any preliminary prospectus.

(d) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a), 8(b) or 8(c) (the "indemnified party"), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(c), or pursuant to both Sections 8(b) and 8(c), the Underwriter shall not be required to assume the defense of such action pursuant to this Section 8(d), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of such Underwriter). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for (i) the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all Underwriters, their officers and directors and all persons, if any, who control any Underwriter within the meaning of either

Section 15 of the Act or Section 20 of the Exchange Act, (ii) the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and all persons, if any, who control the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all Selling Stockholders and all persons, if any, who control any Selling Stockholder within the meaning of either such Section, and all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters, their officers and directors and such control persons of any Underwriters, such firm shall be designated in writing by each of the Representatives. In the case of any such separate firm for the Company and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Stockholders and such control persons of any Selling Stockholders, such firm shall be designated in writing by the Attorneys. The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty business days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party shall have (a) failed to comply with such reimbursement request or (b) contested, in good faith, such fees and expenses of counsel. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the indemnified party.

(e) To the extent the indemnification provided for in this Section 8 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company or the Selling Stockholders on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company or the Selling Stockholders on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company or the Selling Stockholders on the one hand and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses but after deducting underwriting discounts and commissions) received by the Company or the Selling Stockholders, and the total underwriting discounts and commissions received by the Underwriters, bear to the total price to the public of the Shares, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company or the Selling Stockholders on the one hand and the Underwriters on the other hand 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 Company or the Selling Stockholders on the one

hand or the Underwriters on the other hand and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any matter, including any action, that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 8, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no Selling Stockholder shall be required to contribute any amount in excess of the amount by which the proceeds received by such Selling Stockholder from the sale of its Shares exceeds the amount of any damages that such Selling Stockholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 8(e) are several in proportion to the respective number of Shares purchased by each of the Underwriters hereunder and not joint. The Selling Stockholders obligations to contribute pursuant to this Section 8(e) are several in proportion to the respective number of Shares sold by each Selling Stockholder hereunder and not joint.

(f) Each Selling Stockholder that is not a KKR Selling Stockholder hereby designates CT Corporation System, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, as its authorized agent, upon which process may be served in any action which may be instituted in any state or federal court in the State of New York by any Underwriter, any director or officer of any Underwriter or any person controlling any Underwriter asserting a claim for indemnification or contribution under or pursuant to this Section 8, and each such Selling Stockholder will accept the jurisdiction of such court in such action, and waives, to the fullest extent permitted by applicable law, any defense based upon lack of personal jurisdiction or venue. A copy of any such process shall be sent or given to such Selling Stockholder, at the address for notices specified in Section 12 hereof.

This Agreement may be terminated at any time after it becomes effective and prior to the Closing Date by the Representatives by written notice to the Company and the Selling Stockholders if any of the following has occurred: (i) any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other national or international calamity or crisis or change in the economic conditions or in the financial markets of the United States or elsewhere that, in each case, in the Representatives' judgment, is material and adverse and would, in the Representatives' judgment, make it impracticable or inadvisable to market the Shares on the terms and in the manner contemplated in the Prospectus or to deliver the Shares, (ii) the suspension or material limitation of trading in securities on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required by any such exchange, the Nasdaq National Market, by such system or order of the Commission, the NASD or any other governmental authority, (iii) the suspension of trading of any securities of the Company on any exchange or in the over-the-counter market, (iv) the declaration of a banking moratorium by either federal or New York State authorities or (v) a material disruption in commercial banking or securities settlement or clearance services in the United States.

If on the Closing Date or on the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase the Firm Shares or Additional Shares, as the case may be, that it or they have agreed to purchase hereunder on such date, and the aggregate number of Firm Shares or Additional Shares, as the case may be, that such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase is not more than one-tenth of the total

number of Firm Shares or Additional Shares, as the case may be, to be purchased on such date by all Underwriters, each non-defaulting Underwriter shall be obligated severally, in the proportion that the number of Firm Shares set forth opposite its name in Schedule I bears to the total number of Firm Shares that all the non-defaulting Underwriters, as the case may be, have agreed to purchase, or in such other proportion as the Representatives may specify, to purchase the Firm Shares or Additional Shares, as the case may be, that such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase on such date; provided that in no event shall the number of Firm Shares or Additional Shares, as the case may be, that any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Firm Shares or Additional Shares, as the case may be, without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares, and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date by all Underwriters, and arrangements satisfactory to the Underwriters and the Selling Stockholders for purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders. In any such case that does not result in termination of this Agreement, either the Representatives or the Selling Stockholders shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase such Additional Shares or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase on such date in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of any such Underwriter under this Agreement.

SECTION 11. Agreements of the Selling Stockholders. Each Selling Stockholder agrees with the Underwriters and the Company:

(a) To pay or to cause to be paid all transfer taxes payable in connection with the transfer of the Shares to be sold by such Selling Stockholder to the Underwriters.

(b) To do and perform all things to be done and performed by such Selling Stockholder under this Agreement prior to the Closing Date or any Option Closing Date, as the case may be, and to satisfy all conditions precedent to the delivery of the Shares to be sold by such Selling Stockholder pursuant to this Agreement.

SECTION 12. Tax Disclosure. Notwithstanding any other provision of this Agreement, the parties to this Agreement (and each employee, representative or other agent of such party) may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such tax treatment and tax structure.

The respective indemnities, contribution agreements, representations, warranties and other statements of the Company, the Selling Stockholders and the several Underwriters set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, and will survive delivery of and payment for the Shares, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the officers or directors of the Company, any controlling person of the Company, any Selling Stockholder or any person controlling such Selling Stockholder, (ii) acceptance of the Shares and payment for them hereunder and (iii) termination of this Agreement.

If this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Company or any of the Selling Stockholders to comply with the terms hereof or to fulfill any of the conditions set forth in Section 9 of this Agreement, other than by reason of a default under this Agreement by an Underwriter, the Company and the Selling Stockholders agree to reimburse the several Underwriters upon demand accompanied by reasonable supporting documentation for all out-of-pocket expenses (including the reasonable fees and disbursements of counsel) reasonably incurred by them in connection with the matters contemplated by this Agreement.

Except as otherwise provided, this Agreement has been and is made solely for the benefit of and shall be binding upon the Company, the Selling Stockholders, the Underwriters, any controlling persons referred to herein and their respective successors and assigns, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" shall not include a purchaser of any of the Shares from any of the several Underwriters merely because of such purchase.

This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and the Selling Stockholders and, to the extent provided in Section 8 hereof and the preceding paragraph, the officers and directors of the Company and each person who controls the Company, any Selling Stockholder or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

This Agreement may be signed in various counterparts, which together shall constitute one and the same instrument.
