TERMS OF MERGER



2.1.        Effect of Merger and Surviving Corporation.  At the Effective Time of the Merger, Merger Sub will be merged with and into Company pursuant to the terms, conditions and provisions of this Agreement and in accordance with the applicable provisions of the DGCL, and the separate corporate existence of Merger Sub shall cease and Company shall continue as the surviving corporation of the Merger.  The Merger will have the effects set forth in the DGCL.



2.2.         Stock of Company.  Subject to Section 2.6, each share of Company Stock issued and outstanding immediately prior to the Effective Time of the Merger shall, without any further action on the part of Company or the holders of such shares, be treated on the basis set forth in this Section 2.2.

(a)          Cancellation of Treasury Shares.  All shares of Company Stock that are owned by Company as treasury stock and all shares of Company Stock that are owned directly or indirectly by Company or Parent shall be cancelled and shall cease to exist, and no Merger Consideration shall be delivered in exchange therefor.

(b)          Conversion of Company Stock.  At the Effective Time of the Merger, each issued and outstanding share of Company Stock (other than shares to be cancelled in accordance with Section 2.2(a)) shall be automatically canceled and cease to be an issued and outstanding share of Company Stock and (except for Company Dissenting Shares) be converted solely into the right to receive per share consideration (the Merger Consideration) in cash in the amount of $37.50, without interest.

(c)          Company Dissenting Shares.  Notwithstanding anything in this Agreement to the contrary, any shares of Company Stock that are issued and outstanding as of the Effective Time of the Merger and that are held by a stockholder of Company who has properly exercised such holders appraisal rights under the DGCL (the Company Dissenting Shares) shall not be converted into the right to receive the Merger Consideration unless and until such holder shall have failed to perfect, or shall have effectively withdrawn or lost, such holders right to dissent from the Merger under the DGCL and to receive such consideration as may be determined to be due with respect to such Company Dissenting Shares pursuant to and subject to the
requirements of the DGCL and the holders of Company Dissenting Shares shall be entitled to only such rights as are granted by Section 262 of the DGCL.  If any such holder shall have so failed to perfect or have effectively withdrawn or lost such right at the Effective Time of the Merger, each share of such holders Company Stock shall thereupon be deemed to have been converted into and to have become, as of the Effective Time of the Merger, the right to receive, without any interest thereon, the Merger Consideration.  Company shall give Parent (i) prompt notice of any notice or demands for appraisal or payment for shares of Company Stock received by Company and (ii) the opportunity to direct all negotiations and proceedings with respect to any such demands or notices.  Company shall not, without the prior written consent of Parent, or as required by DGCL, make any payment with respect to, or settle, offer to settle or otherwise negotiate, any such demands.

---

2.3.        Company Stock Options.   Each Company Stock Option outstanding as of the Effective Time of the Merger shall be treated in accordance with Section
12.2 or Section 12.3, as applicable.

2.4.        Effect on Merger Sub Stock.   At the Effective Time of the Merger, each issued and outstanding share of capital stock of Merger Sub shall be converted
into and become one fully paid and nonassessable share of common stock of the Surviving Corporation.

2.5.         Exchange Procedures.

(a)          At the Effective Time of the Merger, Parent shall deposit with the Exchange Agent for the benefit of the holders of shares of Company Stock outstanding immediately prior to the Effective Time of the Merger, for exchange in accordance with this Section 2.5 through the Exchange Agent, cash in the amount of the aggregate Merger Consideration payable to such holders of Company Stock pursuant to Section 2.2 in exchange for their shares of Company Stock (collectively, the Exchange Fund).  Such amounts may be invested by the Exchange Agent as directed by Merger Sub or, after the Effective Time of the Merger, the Surviving Corporation; provided that such investments shall be in short-term obligations of the United States of America with
maturities of no more than 30 days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America.  Any income produced by such investments will be payable to the Surviving Corporation or Parent, as Parent directs.

(b)          Parent shall direct the Exchange Agent to mail, promptly after the Effective Time of the Merger, to each holder of record of shares of Company Stock which are represented by (x) a certificate or certificates which immediately prior to the Effective Time of the Merger represented outstanding shares of Company Stock (the Certificates) or (y) an entry to that effect in the shareholder records maintained on behalf of Company by the Company stock transfer agent (the Book Entry Shares), whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.2 hereof, (i) a letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates (if any) shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent and Company may reasonably specify), and (ii) instructions for use in effecting the surrender of the Certificates or authorizing transfer and cancellation of Book Entry Shares in exchange for the Merger Consideration.  Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, or authorizing transfer of Book Entry Shares, together with such letter of transmittal, duly executed, the holder of such shares of Company Stock shall be entitled to receive in exchange therefor the amount of the Merger Consideration which such holder has the right to receive pursuant to Section 2.2 hereof (less any withholding Taxes pursuant to Section 2.11), and any Certificate so surrendered shall forthwith be canceled.  Until surrendered as
contemplated by this Section 2.5, each Certificate and any Book Entry Shares shall be deemed at any time after the Effective Time of the Merger to represent only the right to receive upon such surrender the Merger Consideration to be paid in consideration therefor upon surrender of such Certificate or transfer of the Book Entry Shares, as the case may be, as contemplated

---

by this Section 2.5.  Notwithstanding anything to the contrary set forth herein, if any holder of shares of Company Stock that are not Book Entry Shares should be unable to surrender the Certificates for such shares, because they have been lost or destroyed, such holder shall, if required by Parent or Exchange Agent, deliver in lieu thereof a bond in form and substance and with surety reasonably satisfactory to Parent and shall be entitled to receive the Merger Consideration to be paid in consideration therefor in accordance with Section 2.2 hereof (less any withholding Taxes pursuant to Section 2.11).

(c)          No interest shall be paid or accrued for the benefit of holders of the Certificates or Book Entry Shares on the Merger Consideration payable in respect thereof.  If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Parent that such Tax either has been paid or is not applicable.

(d)          If, after the Effective Time of the Merger, Certificates or Book Entry Shares are presented to Parent for any reason, they shall be canceled and exchanged as provided in this Agreement, subject to the other provisions of this Article 2.

(e)          Any portion of the Exchange Fund which remains undistributed to the former stockholders of Company following the passage of twelve months after the Effective Time of the Merger shall be delivered (together with any income received with respect thereto) to the Surviving Corporation, upon demand, and any former stockholders of Company who have not theretofore complied with this Section 2.5 shall thereafter look only to the Surviving Corporation and/or Parent, subject to any applicable abandoned property, escheat or similar law, only as general creditors thereof for payment of their claim for the Merger Consideration payable in consideration for any Certificate or transfer of any Book Entry Shares.

(f)           Any portion of the Exchange Fund remaining unclaimed as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable law, become the property of Parent free and clear of any claims or interests of any Person previously entitled thereto.  Except as otherwise required by law, none of the Exchange Agent, Parent, Company or the Surviving Corporation shall be liable to any former holder of shares of Company Stock or any other Person for any consideration from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

2.6.        Adjustments.   If after the date hereof and on or prior to the Effective Date of the Merger, the outstanding shares of Company Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization or combination, stock split, reverse stock split, stock dividend or rights issued in respect of such stock, or any similar event shall occur, the Merger Consideration shall be adjusted accordingly to provide to the holders of Company Stock the same economic effect as contemplated by this Agreement prior to such event.

2.7.        Directors of Surviving

11

representation to which the exception or matter reasonably relates to the extent such relationship is reasonably apparent on the face of the disclosure contained in the Company Disclosure Letter.  The inclusion of any item in such Company Disclosure Letter shall not be deemed an admission that such item is a material fact, event or circumstance or that such item has or had, individually or in the aggregate, a Material Adverse Effect.  Subject to the preceding sentences of this paragraph, Company hereby represents and warrants to Parent and Merger Sub as follows:



4.1.        Incorporation, Standing and
Power.   Company has been duly organized, is validly existing and in good standing as a corporation under

properties and assets and to carry on its business as presently conducted. The Company is duly qualified to do business in each
jurisdiction where the character of its properties owned or held under lease or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified would not, individually or in the aggregate, have a Material
Adverse Effect. Company has delivered to Parent true and correct copies of the Companys Certificate of Incorporation and
Bylaws, as currently in effect.



4.2.        Capitalization.



(a)          The authorized capital stock of Company consists of 50,000,000 shares of Company Stock, and 8,484,000 shares of preferred stock, par value $0.01 per share (the Preferred Stock).

unissued capital stock of Company, and Company is not obligated to issue any additional shares of its capital stock or any additional options, warrants or other rights in or with respect to the unissued shares of such stock or any

All government reports and filings required by law have been properly and timely filed and all information required to be distributed to participants or beneficiaries has been distributed with respect to each Employee Plan.  There is no pending or, to the
Companys knowledge, threatened legal action, proceeding or investigation against or involving any Employee Plan or Benefit
Arrangement, other than routine claims for benefits. No prohibited transaction, as defined in Section 406 of ERISA or
Section 4975 of the Code, has occurred with respect to any Employee Plan that could subject the Company or any Person for whom the
Company has an obligation to indemnity to liability under Title I of ERISA or to the imposition of tax under Section 4975 of the
Code (other than any such transaction the cost or liability of which would not have a Material Adverse Effect). No Employee Plan
is subject to Title IV or Part 3 of Subtitle B of Title I of ERISA or Section 412 of the Code. No reportable event as
defined in ERISA has occurred with respect to any of the Employee Plans. All contributions, premiums and other payments required
to be made to each of the Employee Plans or Benefit Arrangement under the terms of the Employee Plan, Benefit Arrangement and
ERISA, the Code or any other applicable laws have been timely made. Except as required by law or as set forth in Section 4.20(c)
of the Company Disclosure Letter, no condition or term under any Employee Plan or Benefit Arrangement exists which would prevent
Parent, the Surviving Corporation or any of their Subsidiaries from terminating or amending any such Employee Plan or Benefit
Arrangement at any time for any reason without liability to Parent, the Surviving Corporation or any of their Subsidiaries (other
than reasonable administrative notice periods, ordinary administration expenses, reasonable administrative expenses related to the
termination process, or routine claims for benefits) that, in the aggregate for all such liability under all such Employee Plans or Benefit Arrangements, would not exceed $100,000.

Arrangement, Parent shall be entitled from time to time to modify, terminate or supplement any such employee plans or benefit arrangements or to substitute new employee plans or benefit arrangements for such employee plans or benefit arrangements in the exercise of their business judgment.

(b)          With respect to any employee plans and benefit arrangements of Parent in which any employees of Company first become eligible to participate on or after the Effective Time of the Merger (New Plans), Parent shall (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements under any such New Plans, except to the extent such conditions or exclusions would have been recognized under the Company Employee Plans or Benefit Arrangements, (ii) recognize service of the employees of Company credited by Company prior to the Effective Time of the Merger for purposes of eligibility and vesting under the New Plans, other than retiree medical plans (and not for purposes of benefit

practicable (but no later than 45 days) after the Effective Time of the Merger, the Parent will cause the Surviving Corporation to
pay or provide to those persons eligible to participate in the Companys Fiscal 2007 Incentive Plan and employed by Company
on the Effective Time of the Merger (and waiving any other employment related condition under the Incentive Plan), (A) the cash
incentive payment under Companys Fiscal 2007 Incentive Plan determined (x) based upon eligible earnings of each employee for
the fiscal year through the Effective Time of the Merger, (y) as if the last day of the month prior to the Effective Time of the
Merger were the last day of the performance period under such plan (Adjusted Performance
Period) and (z) based upon the actual achievement during the Adjusted Performance Period of the
following measures, as applicable: (i) net sales growth for the Adjusted Performance Period as a percentage over actual sales for
the comparable period in fiscal year 2006; (ii) operating income for completed months in the Adjusted Performance Period as a
percentage of the projected operating income for the same months as determined under the Companys operating plan for fiscal

the planned completion of the applicable objective is prior to the Effective Time of the Merger, and (B) the additional matching

anniversary of the Effective Time, Parent will cause the Surviving Corporation to pay and provide to employees of Company whose

and in amounts that are no less favorable to the employee than those in the Companys Severance Pay Plan as in effect as of
the Effective Time of the Merger. Any such severance and other benefits under the Companys Severance Pay Plan shall be in
addition to, and shall not be reduced or offset by any notice pay, severance pay or pay in lieu of notice required under any federal or state statute or regulation.

(ii)   Parent will cause the Surviving
Corporation to assume and perform all of the obligations of Company under the terms of the Executive Employment Agreements and to

is entitled under the terms of the Executive Employment Agreements.

(iii)   In the event Section 409A(a)(1)(B) of the Code
requires a deferral of any payment to an employee who is a key employee as that term is defined in Code 409A, such
payment shall be accumulated and paid in a single lump sum on the earliest date permitted by Code 409A, together with interest for
the period of delay, compounded annually, equal to the prime rate (as published in the Wall Street Journal) and in effect as of
the date the payment should otherwise have been made.

12.2.      Company Stock Options and the Company Stock Option Plans.

Effective Time of the Merger, shall be cancelled (and each holder of a Company Stock Option shall cease to have any rights with respect thereto except as provided in this Section 12.2(a)(ii)) in exchange for a cash payment by Company of an amount equal to (A) the excess, if any, of (x) the Merger Consideration over (y) the exercise price per share of Company Stock subject to such Company Stock Option, multiplied by (B) the number of shares of Company Stock subject to such Company Stock Option.

(b)          All amounts payable pursuant to this Section 12.2 shall be subject to any required withholding of Taxes and shall be paid without interest.

required to delete as of the Effective Time of the Merger the provision in any other Benefit Arrangements of Company providing for
the issuance, transfer or grant of any capital stock of Company or any interest in respect of any capital stock of Company and to
ensure that following the Effective Time of the Merger no holder of a Company Stock Option or any participant in any Company Stock

the Merger (the ESPP Termination Date); (c) the Offering Period in effect as of the ESPP Termination Date shall terminate on the ESPP Termination Date and the extent of each participants purchase rights under the ESPP shall be determined based on the amount of payroll deductions actually withheld on such employees behalf and credited to such employees account as of the ESPP Termination Date; and (iv) upon the Effective Time of the Merger, each outstanding purchase right under the ESPP shall be cancelled (and each participant in the ESPP shall cease to have any rights with respect thereto except as provided in this Section 12.3) in exchange for a cash payment by Company of an amount equal to product of (i) the whole number of shares of Company Stock, rounded down to the nearest whole number, that the participant would have been entitled to purchase under the ESPP had such purchase rights not been cancelled
(subject to the preceding clause (c) and to the provisions of the ESPP regarding the number of shares purchasable) and (ii) the excess, if any, of the Merger Consideration over the lesser of (x) 85% of the Merger Consideration and (y) 85% of the fair market value of a share of Company Stock (determined as provided in the ESPP) on the Commencement Date (as defined in the ESPP) of such Offering Period.  Any excess payroll deductions remaining in a participants account as a result of rounding down or of share purchase limitations under the ESPP shall be distributed to the applicable participant without interest.
