1 EXHIBIT 2.7 DESCRIPTION OF NOTES The Notes are to be issued under an Indenture to be dated as of April 1, 1994 (the "Indenture") between the Company, as issuer, and Texas Commerce Bank National Association, as trustee (the "Trustee"), a copy of which is filed as an exhibit to the Registration Statement of which this Prospectus is a part. The terms of the Indenture are governed by certain provisions contained in the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following summaries of certain provisions of the Indenture do not purport to be complete, and where particular provisions of the Indenture are referred to, such provisions, including the definitions of certain capitalized terms used in this Prospectus, are incorporated by reference as a part of such summaries, which are qualified in their entirety by reference to the provisions of the Indenture. The section ("Section") and article ("Article") references appearing below are to sections and articles of the Indenture. GENERAL The Notes will be unsecured subordinated obligations of the Company, will mature on March 31, 2001 and will be in the aggregate principal amount of $100,000,000 ($115,000,000 aggregate principal amount if the Underwriters' over-allotment option is exercised in full). The Notes will bear interest from the date of issuance at the rate per annum shown on the cover page of this Prospectus. Interest will be payable semi-annually on March 31 and September 30 of each year, commencing September 30, 1994, to the persons in whose names such Notes (or any predecessor Notes) are registered at the close of business on the March 15 or September 15 preceding such Interest Payment Date (Sections 301 and 307). Principal of and premium, if any, and interest on the Notes will be payable, and the Notes will be convertible and may be presented for transfer and exchange, at the office or agency maintained by the Company for such purposes, which will initially be the office of the Trustee located at 80 Broad Street, Fourth Floor, New York, New York 10004. However, at the option of the Company, payment of interest on the Notes may be made by check mailed to the address of persons entitled thereto as shown in the register of the Security Registrar. No service charge will be made upon any registration of transfer or exchange of the Notes, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Indenture does not limit the incurrence of additional indebtedness, including Senior Indebtedness, by the Company. CONVERSION RIGHTS The Notes will be convertible, in whole or from time to time in part (in denominations of $1,000 or integral multiples thereof), at the option of the holder thereof, into Common Stock of the Company, initially at the conversion price stated on the cover page hereof, at any time prior to maturity, unless previously redeemed by the Company. In the case of Notes called for redemption, conversion rights will terminate at the close of business on the fifth business day preceding the Redemption Date. Notwithstanding anything to the contrary in the foregoing, the Notes will not be convertible at any time when payments on the Notes are prohibited under the subordination provisions of the Indenture as described under "-- Subordination of Notes" (Section 1201). If the Company, by dividend or otherwise, declares or makes a distribution on its Common Stock of the type referred to in clause (iv) or (v) below, the holder of each Note, upon the conversion thereof subsequent to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution and prior to the effectiveness of the conversion price adjustment in respect of such distribution pursuant to clause (iv) or (v) below, will be entitled to receive for each share of Common Stock into which such Note is converted the portion of the evidences of indebtedness, shares of capital stock, cash and other assets so distributed applicable to one share of Common Stock; provided, however, that the Company may, with respect to all holders so converting, in lieu of distributing any portion of such distribution not consisting of 27 2 cash or securities of the Company, pay such holder cash in an amount equal to the fair market value thereof, as determined in good faith by the Board of Directors (Section 1201). The conversion price will be subject to adjustment in certain events, including: (i) dividends (and other distributions) payable in Common Stock on any class of capital stock of the Company; (ii) the issuance to all holders of Common Stock of rights, warrants or options entitling them to subscribe for or purchase Common Stock at less than the current market price (as provided in the Indenture); provided, however, that if such rights, warrants or options are only exercisable upon the occurrence of certain triggering events, then the conversion price will not be adjusted until such triggering events occur; (iii) subdivisions and combinations of Common Stock; (iv) distributions to all holders of Common Stock of evidences of indebtedness of the Company, shares of any class of capital stock, cash or other assets (including securities, but excluding those dividends, rights, warrants, options and distributions referred to in clauses (i) and (ii) above and excluding dividends and distributions exclusively paid in cash up to the greater of (x) retained earnings of the Company on the date such distribution or dividend was declared or (y) Net Income (as defined below) of the Company during the four full fiscal quarters preceding the date such distribution or dividend was declared, and other than in connection with a tender offer or other negotiated purchase made by the Company or any Subsidiary for all or a portion of the Common Stock); provided, however, that if any rights, warrants or options in respect of which an adjustment is provided for in this clause (iv) are only exercisable upon the occurrence of certain triggering events, then the conversion price will not be adjusted until such triggering events occur; (v) distributions consisting exclusively of cash (specifically including distributions paid in cash up to the greater of (x) retained earnings of the Company on the date such distribution or dividend was declared or (y) Net Income of the Company during the four full fiscal quarters preceding the date such distribution or dividend was declared, but excluding any cash distributions for which an adjustment has been made pursuant to a preceding clause of this paragraph) to all holders of Common Stock in an aggregate amount that, together with (A) other all-cash distributions made within the preceding 12 months not triggering a conversion price adjustment and (B) all Excess Tender Payments (as defined below) in respect of each tender or exchange offer by the Company or any Subsidiary for Common Stock concluded within the preceding 12 months not triggering a conversion price adjustment, exceeds an amount equal to 20% of the Company's deemed market capitalization on the date fixed for the determination of stockholders entitled to receive such distribution (calculated as set forth in the Indenture); (vi) issuances of Common Stock to an Affiliate for a net consideration per share less than the current market price per share (other than issuances of Common Stock under certain management benefit plans); and (vii) payment of an Excess Tender Payment in respect of a tender or exchange offer by the Company or any Subsidiary for Common Stock, if the aggregate amount of such Excess Tender Payment, together with (A) the aggregate amount of any all-cash distributions made within the preceding 12 months not triggering a conversion price adjustment and (B) all Excess Tender Payments in respect of each tender or exchange offer by the Company or any Subsidiary for Common Stock concluded within the preceding 12 months not triggering a conversion price adjustment, exceeds an amount equal to 20% of the Company's deemed market capitalization on the expiration of such tender offer (calculated as set forth in the Indenture) (Section 1204). For purposes of these conversion price adjustments, the term (i) "Excess Tender Payment" means the excess of (A) the aggregate of the cash and value of other consideration paid by the Company with respect to the shares acquired in the tender or exchange transaction over (B) the market value of such acquired shares after the completion of the tender or exchange offer (calculated as set forth in the Indenture) and (ii) "Net Income" of any Person means the net income of such Person net of non-cash charges taken as a result of accounting changes required to be made by the Financial Accounting Standards Board after the date of the Indenture. No adjustments in the conversion price are required for any dividend or distribution referred to above if the holders may participate in the dividend or distribution (on a basis determined in good faith to be fair by the Board of Directors) and receive the same consideration they would have received if they had converted the Notes (Section 1213). No adjustment of the conversion price will be required to be made until cumulative adjustments amount to 1% or more of the conversion price as last adjusted. In addition to the foregoing adjustments, the Company will be permitted to make such reductions in the conversion price as it considers to be advisable in order that 28 3 any event treated for federal income tax purposes as a dividend of stock or stock rights will not be taxable to the recipient (Section 1204). Subject to any applicable right of the holders to receive the Change of Control Purchase Price (as described below), in the case of certain consolidations or mergers to which the Company is a party or the transfer or lease of the Company's properties or assets substantially as an entirety, each holder has the right to convert each Note only into the kind and amount of securities, cash and other property receivable upon the consolidation, merger, transfer or lease by a holder of the number of shares of Common Stock into which such Note might have been converted immediately prior to such consolidation, merger, transfer or lease (assuming such holder of Common Stock is not a Constituent Person and such holder failed to exercise any rights of election and received per share the kind and amount of consideration received per share by a plurality of non-electing shares) (Section 1211). Fractional shares of Common Stock will not be issued upon conversion, but, in lieu thereof, the Company will pay a cash adjustment based upon the market price of a share of Common Stock (Section 1203). Except as provided below, no adjustment will be made upon a conversion of Notes for interest accrued thereon. The Company's delivery to the holder of the fixed number of shares of Common Stock into which the Note is convertible will be deemed to satisfy the Company's obligation to pay the principal amount of the Note and all accrued interest that has not previously been paid. If a Note is surrendered for conversion during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the close of business on any Interest Payment Date, then notwithstanding such conversion, interest payable in respect of the Note so surrendered will be paid in cash to the person in whose name such Note is registered at the close of business on such Regular Record Date, and (except in the case of Notes with a Maturity Date prior to such Interest Payment Date) when so surrendered for conversion, such Note must be accompanied by payment of an amount equal to the interest thereon which the registered holder as of the close of business on such Regular Record Date is to receive (Sections 307 and 1202). SUBORDINATION OF NOTES The payment of the principal of and premium, if any, and interest on the Notes is, to the extent set forth in the Indenture, subordinated in right of payment to the prior payment in full of all Senior Indebtedness, whether now outstanding or incurred in the future (Section 1301). Upon any payment or distribution of assets of the Company to creditors upon any liquidation, dissolution, winding up, assignment for the benefit of creditors or marshalling of assets and liabilities or any bankruptcy, insolvency, receivership, liquidation, reorganization or similar proceedings of the Company, the holders of all Senior Indebtedness will first be entitled to receive payment in full of all amounts due or to become due thereon before the holders of the Notes will be entitled to receive any payment (other than any payment in the form of Permitted Junior Securities) on account of the principal of or premium, if any, or interest on the Notes, including payment of the Redemption Price and the Change of Control Purchase Price of the Notes, and before the Notes may be converted into Common Stock (Section 1302). No payment (other than any payment in the form of Permitted Junior Securities) on account of principal of and premium, if any, or interest on the Notes, including payment of the Redemption Price and the Change of Control Purchase Price on the Notes, may be made, and the Notes may not be converted into Common Stock, if a Payment Event of Default shall have occurred and be continuing. In addition, no payment (other than any payment in the form of Permitted Junior Securities) on account of principal of or premium, if any, or interest on the Notes, including payment of the Redemption Price and the Change of Control Purchase Price on the Notes, may be made, and the Notes may not be converted into Common Stock, if a Non-payment Event of Default shall have occurred and be continuing, for the period (a "Payment Blockage Period") commencing on receipt of notice of such event of default by the Trustee from holders of at least a majority in principal amount of any Designated Senior Indebtedness (or any trustee or other representative therefor) and ending on the earlier of (i) the date such Non-payment Event of Default has been cured or waived or has ceased to exist or any acceleration of such Designated Senior Indebtedness has been rescinded or annulled or such Designated Senior Indebtedness shall have been discharged and (ii) the date 176 days after such receipt 29 4 of notice. Any number of such notices may be given; provided, however, that, during any 360-day period, the aggregate Payment Blockage Periods shall not exceed 176 days and there shall be a period of at least 184 consecutive days when no Payment Blockage Period is in effect. No default existing or continuing when a Payment Blockage Period begins may be the basis for any subsequent Payment Blockage Period unless such default has been cured for a period of at least 90 consecutive days. In the event that, notwithstanding the restrictions described in the preceding sentences, the Company makes any payment to the Trustee or a holder of Notes prohibited by any such restriction, with such Trustee or holder, as the case may be, knowing of such contravention before receipt thereof, then such payment will be required to be paid over and delivered forthwith to the Company to the extent necessary to pay in full all such Senior Indebtedness (Section 1303). The subordination rights of holders of Senior Indebtedness will not be prejudiced or impaired by any acts or failures to act by the Company or by any such holder (Section 1308). The subordination of the Notes set forth above will not prevent the occurrence of any Event of Default under the Indenture. Furthermore, the subordination of the Notes as set forth above will not impair, as between the Company, the holders of the Notes and creditors of the Company other than holders of Senior Indebtedness, the obligations of the Company to make payments on the Notes in accordance with their terms. In certain circumstances, as set forth in the Indenture, the holders of Notes will be subrogated to certain rights of the holders of Senior Indebtedness upon payment in full of all Senior Indebtedness (Section 1302). By reason of such subordination, in the event of insolvency of the Company, the holders of Senior Indebtedness (as well as other creditors of the Company who are holders of indebtedness that is not subordinated to the Senior Indebtedness) may recover more, ratably, than the holders of the Notes. The Notes will also be effectively subordinated to all liabilities, including trade payables and capitalized lease obligations, if any, of the Company's subsidiaries. Any right of the Company to receive the assets of any of its subsidiaries upon their liquidation or reorganization (and the consequent right of the holders of the Notes to participate in those assets) will be subject to the prior payment of claims of that subsidiary's creditors (including trade creditors), except to the extent that the Company is itself a creditor of such subsidiary, in which case the claims of the Company would still be subject to the prior payment of claims secured by security interests in the assets of such subsidiary and any other indebtedness of such subsidiary senior to that held by the Company. Immediately following the sale of the Notes offered hereby and application of the proceeds therefrom, the Company estimates that the sum of its Senior Indebtedness and the indebtedness of its subsidiaries will total approximately $50 million. There are no restrictions in the Indenture on the creation of Senior Indebtedness (or any other indebtedness). The agreements under which Senior Indebtedness may be outstanding in the future could contain provisions which may require repayment of such respective Senior Indebtedness prior to repayment of the Notes upon, among other things, a Change of Control. If the Company is unable to obtain the requisite consents under its Senior Indebtedness to enable it to repurchase the Notes or is unable to repay all Senior Indebtedness, there would be both an Event of Default under the Notes and an event of default under such Senior Indebtedness, as a result of which events the Company would be prohibited by the subordination terms of the Indenture from repurchasing Notes or making other payments in respect thereof. Furthermore, the exercise by the holders of their right to require the Company to repurchase the Notes could cause a default under the Designated Senior Indebtedness of the Company, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Company. As a result, the repurchase of the Notes could be blocked pursuant to the subordination terms of the Indenture. Finally, the Company's ability to pay cash to the holders of Notes upon a repurchase may be limited by the Company's then existing financial resources. Failure of the Company to pay the Change of Control Purchase Price will create an Event of Default with respect to the Notes, whether or not such repurchase is permitted by the subordination terms of the Indenture. See " -- Repurchase of Notes at the Option of the Holder Upon a Change of Control." "Bank Credit Facility" means the Company's existing bank credit facility and any renewals, amendments, extensions, supplements, modifications, refinancings or replacements thereof (Section 101). "Designated Senior Indebtedness" means (i) all Senior Indebtedness under the Bank Credit Facility if the sum of the amounts outstanding under the Bank Credit Facility and the amounts available for borrowing 30 5 thereunder is equal to or greater than $25,000,000 and (ii) all other Senior Indebtedness having an outstanding principal amount equal to or greater than $25,000,000 (provided, however, that the agreements, indentures or other instruments evidencing any Senior Indebtedness referred to in this clause (ii) specifically state that such Senior Indebtedness shall be classified as "Designated Senior Indebtedness" for purposes of the Indenture) (Section 101). "Indebtedness" of any Person means, without duplication, (i) every obligation of such Person for money borrowed; (ii) every obligation of such Person evidenced by bonds, debentures, notes or similar instruments, including obligations incurred in connection with the acquisition of property, assets or businesses; (iii) every obligation of such Person under conditional sale or other title retention agreements relating to assets or property purchased by such Person or issued or assumed as the deferred purchase price of property, assets or services (but excluding trade accounts payable or accrued liabilities arising in the ordinary course of business that are not overdue by more than 90 days or are being contested by such Person in good faith); (iv) every Capital Lease Obligation of such Person; (v) every obligation of such Person with respect to any Sale and Leaseback Transaction to which such Person is a party; (vi) every obligation of such Person with respect to letters of credit, bankers acceptances or similar facilities issued for the account of such Person; (vii) the maximum fixed redemption or repurchase price of outstanding Redeemable Stock of such Person; (viii) every obligation of such Person with respect to performance, surety or similar bonds; (ix) every obligation of such Person under interest rate, commodity or foreign currency swap, cap, hedge, exchange or similar agreements; (x) every obligation of the type referred to in clauses (i) through (ix) and clause (xi) of another Person the payment of which such Person has Guaranteed or is otherwise responsible for or liable for, directly or indirectly, as obligor, Guarantor or otherwise; and (xi) every amendment, modification, renewal and extension of an obligation of the type referred to in clauses (i) through (x) (Section 101). "Non-payment Event of Default" means any event (other than a Payment Event of Default) the occurrence of which entitles any one or more persons to accelerate the maturity of any Designated Senior Indebtedness (Section 101). "Payment Event of Default" means any default in the payment of principal of or premium, if any, or interest on any Designated Senior Indebtedness when due (whether at maturity, upon acceleration or otherwise) (Section 101). "Permitted Junior Securities" means subordinated debt securities of the Company (or any successor obligor with respect to the Senior Indebtedness) provided for by a plan of reorganization or readjustment that are subordinated in right of payment to all Senior Indebtedness that may be outstanding to substantially the same extent as, or to a greater extent than, the Notes are subordinated as provided in the Indenture (Section 101). "Senior Indebtedness" means all obligations of the Company for Indebtedness (other than Indebtedness described in clause (vii) of the definition of Indebtedness), whether now existing or hereafter incurred or assumed; provided that, Senior Indebtedness shall not include (A) any obligation owed to a Subsidiary or an Affiliate or Related Person of the Company, (B) any obligation that by its terms is not superior in right of payment to the Notes, (C) any obligation in respect of the Company's 8% Convertible Subordinated Debentures and 6% Convertible Subordinated Debentures, if and when issued, for which the Company's existing preferred stock is exchangeable (the Notes not being senior in right of payment to such debentures) or (D) any obligation constituting a trade account payable (Section 101). 31 6 REDEMPTION The Notes will be redeemable, at the Company's option, as a whole or from time to time in part, at any time on or after March 31, 1997, upon not less than 20 nor more than 60 days notice mailed to the registered holders thereof, at the redemption prices (expressed as a percentage of the principal amount thereof) set forth below if redeemed during the 12-month period beginning March 31 of the years indicated: YEAR REDEMPTION PRICE ---------------------------------------------- ---------------- 1997.......................................... % 1998.......................................... % 1999.......................................... % 2000.......................................... % together, in each case, with accrued interest to the Redemption Date (subject to the right of holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date) (Sections 203, 1101, and 1107). If less than all the Notes are to be redeemed, the Notes to be redeemed shall be selected by the Trustee in such manner as the Trustee shall deem appropriate and fair (Section 1104). The Company's existing bank credit facility prohibits the Company from redeeming any Notes unless (i) such redemption is permitted under the restricted payment covenant contained in such bank credit facility and (ii) at the time of such redemption and after giving effect thereto, no default shall have occurred under such bank credit facility. REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL In the event of any Change of Control (as defined below) with respect to the Company which constitutes a Repurchase Event (as defined below), each holder of Notes will have the right, at such holder's option, subject to the terms and conditions of the Indenture, to require the Company to repurchase all or any part (provided that the principal amount must be $1,000 or an integral multiple thereof) of the holder's Notes on the date (the "Change of Control Purchase Date") that is 60 days after the date the Company's Change of Control Notice (as defined below) is mailed (or such later date as is required by law), at a cash price equal to 100% of the principal amount plus accrued interest to the Change of Control Purchase Date (the "Change of Control Purchase Price"). The Change of Control Purchase Price may be less than the fair market value of the Notes on the Change of Control Purchase Date. Promptly, but in any event within 29 days following any Change of Control, the Company is required, with respect to any Senior Indebtedness that would prohibit the repurchase of Notes by the Company in the event of such Change of Control, either to repay all such Senior Indebtedness in full or obtain the requisite consents under such Senior Indebtedness to permit the repurchase of the Notes as provided below. The Company first is required to comply with the covenants in the preceding sentence before it is required to repurchase Notes pursuant to a Change of Control. The foregoing will in no way limit the occurrence of an Event of Default, including an Event of Default arising from a default under the covenants of the second sentence of this paragraph (Section 1401 and 1402). Within 29 days after a Change of Control which constitutes a Repurchase Event, the Company is obligated to mail to the Trustee and to all holders of Notes at their addresses shown in the register of the Security Registrar (and to beneficial owners as required by applicable law) a notice (the "Change of Control Notice") regarding the Change of Control. The Change of Control Notice will describe: (i) the events causing the Change of Control; (ii) the Change of Control Purchase Price; (iii) the Change of Control Purchase Date; (iv) information regarding the conversion rights of the Notes; and (v) the procedures for withdrawing a Change of Control Purchase Notice. The Change of Control Notice will also state whether or not the Company has satisfied its obligations regarding Senior Indebtedness referred to in the preceding paragraph (Section 1401). To exercise the right to have Notes repurchased following a Change of Control, a holder must deliver a Change of Control Purchase Notice to the Paying Agent at its office maintained for such purpose, prior to the 32 7 close of business on the Change of Control Purchase Date. The Change of Control Purchase Notice shall state: (i) the certificate numbers of the Notes to be delivered by the holder thereof for purchase by the Company; (ii) the portion of the principal amount of Notes to be repurchased, which portion must be $1,000 or an integral multiple thereof; and (iii) that such Notes are to be repurchased by the Company pursuant to the applicable provision of the Indenture (Section 1401). A holder of record of Notes shall be entitled to deliver a Change of Control Purchase Notice with respect to any or all Notes held by it; provided, however, that such holder may be required to provide evidence satisfactory to the Company that, with respect to each beneficial holder of the Notes to be delivered to the Company, such beneficial holder is exercising the right to require the repurchase of all of the Notes in which it has a beneficial interest. Any Change of Control Purchase Notice may be withdrawn by the holder by a written notice of withdrawal delivered to the Paying Agent prior to the close of business on the Change of Control Purchase Date. The notice of withdrawal shall state the principal amount and the certificate numbers of the Notes as to which the withdrawal notice relates and the principal amount, if any, which remains subject to a Change of Control Purchase Notice (Sections 1401 and 1402). Payment of the Change of Control Purchase Price for Notes for which a Change of Control Purchase Notice has been delivered and not withdrawn is conditioned upon delivery of such Notes (together with necessary endorsements) to the Paying Agent at its office maintained for such purpose, at any time (whether prior to, on, or after the Change of Control Purchase Date) after the delivery of such Change of Control Purchase Notice. Payment of the Change of Control Purchase Price for such Notes will be made promptly following the later of the Change of Control Purchase Date and the time of delivery of such Notes (Sections 1401 and 1402). "Change of Control" shall occur when: (i) all or substantially all of the Company's assets are sold as an entirety to any person or related group of persons; (ii) there shall be consummated any consolidation or merger of the Company (A) in which the Company is not the continuing or surviving corporation (other than a consolidation or merger with a wholly-owned subsidiary of the Company in which all shares of Common Stock outstanding immediately prior to the effectiveness thereof are changed into or exchanged for the same consideration) or (B) pursuant to which the Common Stock would be converted into cash, securities or other property, in each case other than a consolidation or merger of the Company in which the holders of the Common Stock immediately prior to the consolidation or merger have, directly or indirectly, at least a majority of the Common Stock of the continuing or surviving corporation immediately after such consolidation or merger; or (iii) any person or any persons acting together which would constitute a "group" for purposes of Section 13(d) of the Exchange Act (other than the Company, any Subsidiary, any employee stock purchase plan, stock option plan or other stock incentive plan or program, retirement plan or automatic dividend reinvestment plan or any substantially similar plan of the Company or any Subsidiary or any person holding securities of the Company for or pursuant to the terms of any such employee benefit plan), together with any affiliates thereof, shall Beneficially Own, directly or indirectly, at least 50% of the total Voting Stock of the Company (Section 1401). As noted above, one of the events that constitutes a Change of Control is a sale of all or substantially all of the assets of the Company as an entirety to any person or related group of persons. The Indenture will be governed by New York law, and there is no established quantitative definition under New York law of "substantially all" of the assets of a corporation. This uncertainty may make it more difficult for a holder of Notes to determine whether a Change of Control has occurred in the event that the Company were to engage in a transaction in which it sold less than all of its assets. A Change of Control as described above shall constitute a Repurchase Event unless (i) the closing price per share of the Common Stock on the five consecutive Trading Days selected by the Company out of the 10 consecutive Trading Days ending immediately after the later of the Change of Control or the public announcement of the Change of Control (in the case of a Change of Control under clauses (i) or (ii) of the definition of Change of Control) or ending immediately before the Change of Control (in the case of a Change of Control under clause (iii) of the definition of Change of Control) is at least equal to 105% of the conversion price of the Notes in effect immediately preceding the time of such Change of Control, or (ii) all 33 8 of the consideration (excluding cash payments for fractional shares) in the transaction giving rise to such Change of Control to the holders of Common Stock consists of shares of common stock that are, or immediately upon issuance will be, listed on a national securities exchange or quoted in the Nasdaq National Market, and as a result of such transaction the Notes become convertible solely into such Common Stock and neither Moody's Investors Service, Inc. nor Standard & Poor's, principally as a result of the Change of Control, has downgraded the rating on the Notes by one or more gradations below the rating of the Notes on the original issuance date thereof within 90 days after the date of the public announcement of the Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by any of the rating agencies), or (iii) the consideration in the transaction giving rise to such Change of Control to the holders of Common Stock consists of cash, securities that are, or immediately upon issuance will be, listed on a national securities exchange or quoted in the Nasdaq National Market, or a combination of cash and such securities, and the aggregate fair market value of such consideration (which, in the case of such securities, shall be equal to the average of the daily closing prices of such securities on the five consecutive Trading Days selected by the Company out of the 10 consecutive Trading Days following consummation of such transaction) is at least 105% of the conversion price of the Notes in effect on the date immediately preceding the closing date of such transaction (Section 1401). The Company, to the extent applicable and if required by law, will comply with the provisions of Rule 13e-4 and any successor or similar provision under the Exchange Act which may then be applicable and will file a Schedule 13E-4 or any successor or similar schedule required thereunder in connection with any offer by the Company to purchase Notes at the option of holders upon a Change of Control (Section 1405). The Change of Control purchase feature of the Notes may in certain circumstances make more difficult or discourage a takeover of the Company and, thus, the removal of incumbent management. The Change of Control purchase feature, however, is not the result of management's knowledge of any specific effort to accumulate shares of Common Stock or to obtain control of the Company by means of a merger, tender offer, solicitation or otherwise, or part of any plan by management to adopt a series of anti-takeover provisions. Instead, the Change of Control purchase feature is a result of negotiations between the Company and the Underwriters. Management has no present intention to engage in a transaction involving a Change of Control, although it is possible that the Company would decide to do so in future. Subject to the limitation on mergers discussed below, the Company could, in the future, enter into certain transactions, including certain recapitalizations, sales of assets, or the liquidation of the Company, that would not constitute a Change of Control under the Indenture, but that would increase the amount of Senior Indebtedness (or any other indebtedness) outstanding at such time or substantially reduce or eliminate the Company's assets. There are no restrictions in the Indenture on the creation of additional Senior Indebtedness (or any other indebtedness), and, under certain circumstances, the incurrence of significant amounts of additional indebtedness could have an adverse effect on the Company's ability to service its indebtedness, including the Notes. If a Change of Control were to occur, there can be no assurance that the Company would have sufficient funds to pay the Change of Control Purchase Price for all Notes tendered by the holders thereof. No Note may be purchased pursuant to the Change of Control provisions if there has occurred and is continuing an Event of Default described under "-- Events of Default" (Section 1402). The Company's existing bank credit facility prohibits the Company from repurchasing any Notes unless (i) such repurchase is permitted under the restricted payment covenant contained in such bank credit facility and (ii) at the time of such repurchase and after giving effect thereto, no default shall have occurred under such bank credit facility. In addition, the agreements under which Senior Indebtedness may be outstanding in the future could contain provisions which may require repayment of such respective Senior Indebtedness prior to repayment of the Notes upon, among other things, a Change of Control. If the Company is unable to obtain the requisite consents under its Senior Indebtedness to enable it to repurchase the Notes or is unable to repay all Senior Indebtedness, there would be both an Event of Default under the Notes and an event of default under such Senior Indebtedness, as a result of which events the Company could be prohibited by the subordination provisions of the Indenture from repurchasing Notes or making other payments in respect thereof. Furthermore, the exercise by the holders of their right to require the Company to repurchase the 34 9 Notes could cause a default under the Senior Indebtedness of the Company, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Company. As a result, the repurchase of the Notes could be blocked pursuant to the subordination terms of the Indenture. Finally, the Company's ability to pay cash to the holders of Notes upon a repurchase may be limited by the Company's then existing financial resources. Failure of the Company to pay the Change of Control Purchase Price will be a default under the Indenture and could result in an Event of Default with respect to the Notes, whether or not such repurchase is permitted by the subordination provisions. See "-- Events of Default." LIMITATION ON MERGERS The Company may, without the consent of the holders of the Notes, consolidate with or merge into any other entity or convey, transfer or lease its properties and assets substantially as an entirety to any person, provided that: (1) the entity formed by such consolidation or into which the Company is merged or the person that acquires by conveyance or transfer, or which leases the properties and assets of the Company substantially as an entirety, must be a corporation, partnership or trust organized and existing under the laws of the United States, any state thereof or the District of Columbia; (2) the successor entity expressly assumes, by a supplemental indenture executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and premium, if any, and interest on all Notes and the performance of every covenant of the Indenture on the part of the Company to be performed or observed and provides for conversion rights in accordance with the Indenture; and (3) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time, or both, would become an Event of Default, shall have occurred and be continuing (Section 801). Upon compliance with these provisions by a successor entity, the Company (except in the case of a lease) would be relieved of its obligations under the Indenture and the Notes (Section 802). MODIFICATION AND WAIVER Modifications and amendments of the Indenture, with certain exceptions, may be made by the Company and the Trustee, only with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, and holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may waive compliance by the Company with certain provisions of the Indenture; provided, however, that no such modification, amendment or waiver may, without the consent of the holder of each outstanding Note affected thereby, (i) change the Stated Maturity of the principal of or the due date of any installment of interest on any Note, (ii) reduce the principal amount of, or the rate of interest on, or any premium payable upon redemption of, any Note, (iii) change the currency of payment of principal of, or premium, if any, or interest on, any Note, (iv) impair the right to institute suit for the enforcement of any payment on or with respect to any Note on or after the Stated Maturity, or the Redemption Date in case of the redemption of any Note, (v) adversely affect the right of a holder to convert Notes, (vi) modify the provisions of the Indenture with respect to the subordination of the Notes in a manner adverse to the holders, (vii) reduce the above-stated percentage of outstanding Notes necessary to modify or amend the Indenture, or (viii) reduce the percentage in aggregate principal amount of outstanding Notes necessary for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults (Sections 902 and 1009). The holders of a majority in aggregate principal amount of the outstanding Notes may waive any past default under the Indenture except, among other things, a default in the payment of principal of or premium, if any, or interest on any Note, including the Redemption Price, or a default with respect to right of holders to convert the Notes (Section 513). EVENTS OF DEFAULT The following will be Events of Default under the Indenture: (i) failure to pay principal of, premium, if any, or Redemption Price when due on any Note, whether or not such payment is prohibited by the subordination provisions of the indenture; (ii) failure to pay any interest on any Note 30 days after payment is due, whether or not such payment is prohibited by the subordination provisions of the Indenture; (iii) failure to perform any other covenant of the Company in the Indenture, and such failure continues for 60 days after 35 10 written notice by the Trustee or the holders of at least 25% in principal amount of the outstanding Notes as provided in the Indenture; (iv) default under any mortgage, indenture or instrument under which there may be issued, or by which there may be secured or evidenced, any indebtedness of the Company in excess of an aggregate of $10,000,000 either for borrowed money or representing any Senior Indebtedness (other than indebtedness which is nonrecourse to the Company beyond the property securing such indebtedness) resulting in the acceleration of such indebtedness prior to its express maturity (provided however, that the Event of Default under this clause (iv) shall be automatically deemed remedied and cured if the default under such accelerated indebtedness is remedied or cured by the Company or waived by the holder of such indebtedness); and (v) certain events of bankruptcy, insolvency or reorganization of the Company (Section 501). Notwithstanding the 60-day period and notice requirement referred to in clause (iii) above, with respect to a default under the Change of Control provisions, (1) the 60-day period referred to in clause (iii) above will be deemed to have begun as of the date the Change of Control Notice is required to be sent in the event the Change of Control Notice indicates (or would, if sent, indicate) that the Company has not complied with its obligation to either repay or obtain the requisite consents under any Senior Indebtedness that would prohibit the repurchase of the Notes, and either (a) the holders duly elect to have at least 25% in principal amount of outstanding Notes repurchased or (b) the holders of at least 25% in principal amount of the outstanding Notes or the Trustee thereafter gives the Notice of Default to the Company and, if applicable, the Trustee, and (2) if the breach or default is a result of a default in the payment when due of the Change of Control Purchase Price on the Change of Control Purchase Date, such default shall arise on the Change of Control Purchase Date, provided that either the holders of at least 25% in principal amount of the Notes or the Trustee thereafter gives the Notice of Default to the Company and, if applicable, the Trustee (Section 501). Subject to the provisions of the Indenture relating to the duties of the Trustee in case an Event of Default shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders, unless such holders shall have offered to the Trustee reasonable indemnity (Sections 601 and 603). Subject to such provisions for the indemnification of the Trustee, the holders of a majority in aggregate principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee (Section 512). If an Event of Default shall occur and be continuing, other than an event of bankruptcy, insolvency or reorganization of the Company, either the Trustee or the holders of at least 25% of the principal amount of the outstanding Notes may accelerate the maturity of all Notes upon the earlier of (1) five business days after notice of such acceleration is received by the Company (and the Trustee if given by holders) and (2) a payment default under or acceleration of any Senior Indebtedness or such other earlier time as the final maturity date for such Senior Indebtedness occurs. If an Event of Default shall occur and be continuing which is an event of bankruptcy, insolvency or reorganization of the Company, the maturity of all Notes shall immediately accelerate without any act on the part of the Trustee or any holder. If an Event of Default shall occur and be continuing as a result of an acceleration of indebtedness of the type described in clause (iv) above, a declaration of acceleration under the Indenture shall automatically be annulled if the holders of the accelerated indebtedness described in clause (iv) above have rescinded their declaration of acceleration within 90 days thereof and no other Event of Default has occurred during such 90-day period which has not been cured or waived. After acceleration upon the Event of Default, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of outstanding Notes may, under certain circumstances, rescind and annul such acceleration if, among other things, all Events of Default, other than the non-payment of accelerated principal, have been cured or waived as provided in the Indenture (Section 502). For information as to waiver of defaults, see "-- Modification and Waiver." No holder of any Note will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such holder shall have previously given to the Trustee written notice of a continuing Event of Default, the holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, the Trustee shall not have received from the holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request and the Trustee shall have failed to 36 11 institute such proceeding within 60 days after such notice (Section 507). However, such limitations do not apply to a suit instituted by a holder of a Note for the enforcement of payment of the principal of or premium, if any, or interest on such Note or the Redemption Price on or after the respective due dates expressed in such Note or of the right to convert such Note in accordance with the Indenture (Section 508). The Company will be required annually to furnish to the Trustee a statement as to any default in its performance of certain of its obligations under the Indenture (Section 1004). DISCHARGE OF INDENTURE; DEFEASANCE The Company may terminate substantially all obligations under the Indenture at any time by delivering all outstanding Notes to the Trustee for cancellation and paying any other sums payable under the Indenture (Article IV). The Indenture also provides that the Company may elect: (a) to defease and be discharged from any and all obligations with respect to the Notes and that the provisions of the Indenture (including the provisions described under "-- Subordination of Notes") will no longer be in effect with respect to the Notes (except for the obligations to register the transfer or exchange of the Notes, to replace temporary or mutilated, destroyed, lost or stolen Notes, to maintain an office or agency in respect of Notes and to hold monies for payment in trust) ("Defeasance"); or (b) to be released from its obligations with respect to the Notes under certain restrictive covenants of the Indenture, and that the event of the type described under the clause (iv) under "-- Events of Default" will not be deemed to be an Event of Default under the indenture and that the provisions described under "-- Subordination of Notes" will not apply ("Covenant Defeasance"). Such Defeasance or Covenant Defeasance will take effect only upon the deposit with the Trustee (or other qualifying trustee), in trust for such purpose, of money or U.S. Government Obligations that, through the payment of principal and interest in accordance with their terms, will provide money, in an amount sufficient to pay the principal of and premium, if any, and interest on the Notes on the dates such payments are due, which may include one or more Redemption Dates designated by the Company (other than in connection with a Change of Control occurring after such Defeasance or Covenant Defeasance), in accordance with the terms of the Notes (Article XV). Such a trust may be established with respect to the Notes only if, among other things: (i) such Defeasance or Covenant Defeasance will not result (whether immediately or with notice or lapse of time or both) in an Event of Default under the Indenture; (ii) such deposit will not be prohibited by the provisions of any agreement or instrument to which the Company is a party or is bound; (iii) such deposit will not cause the Trustee to have any conflicting interest with respect to other securities of the Company; (iv) the Company has delivered to the Trustee an Opinion of Counsel to the effect that the holders of the Notes will not recognize income, gain or loss for federal income tax purpose as a result of such Defeasance or Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Defeasance or Covenant Defeasance had not occurred; and (v) the Company has delivered an Officers' Certificate and an Opinion of Counsel, each to the effect that all conditions precedent relating to such Defeasance or Covenant Defeasance have been satisfied. Such Opinion of Counsel, in the case of Defeasance, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable federal income tax law occurring after the issue date (Article XV). If the Company omits to comply with its remaining obligations under the Indenture after Covenant Defeasance in respect of the Notes issued thereunder and the Notes are declared due and payable because of the occurrence of an Event of Default, the amount of money or U.S. Government Obligations on deposit with the Trustee may be insufficient to pay amounts due on the Notes at the time any acceleration of the maturity thereof resulting from such Event of Default. However, the Company will remain liable in respect of such payments (Article XV). 37 12 GOVERNING LAW The Indenture and the Notes will be governed by and construed in accordance with the laws of the State of New York. THE TRUSTEE Texas Commerce Bank National Association is the Trustee under the Indenture. In the ordinary course of business the Company maintains other commercial relationships with the Trustee and its affiliates. If the Trustee shall acquire any conflicting interest (as defined in Section 301(b) of the Trust Indenture Act) after a default under the Indenture, the Trustee either shall eliminate such conflicting interest or resign as Trustee. DESCRIPTION OF CAPITAL STOCK AUTHORIZED CAPITAL STOCK The Company's authorized capital stock consists of 75,000,000 shares of common stock, par value $.01 per share (the "Common Stock"), of which 23,259,658 were issued and outstanding at December 31, 1993, and 10,000,000 shares of preferred stock, par value $.01 per share (the "Preferred Stock"), of which 2,221,005 were issued and outstanding as of December 31, 1993. COMMON STOCK All shares of Common Stock have equal rights to participate in dividends and, in the event of liquidation, assets available for distribution to stockholders, subject to any preference established with respect to Preferred Stock. Each holder of Common Stock is entitled to one vote for each share held on all matters submitted to a vote of stockholders, and voting rights for the election of directors are noncumulative. Shares of Common Stock carry no conversion, preemptive or subscription rights, and are not subject to redemption. All outstanding shares of Common Stock are, and any shares of Common Stock issued upon conversion of convertible securities will be, validly issued, fully paid and nonassessable. The Company pays dividends on Common Stock when, as and if declared by the Board of Directors. Dividends may be declared in the discretion of the Board of Directors from funds legally available therefor, subject to restrictions under agreements related to Company indebtedness. The transfer agent for the Common Stock is Society National Bank, 3200 Renaissance Tower, 1201 Elm Street, Dallas, Texas 75270. PREFERRED STOCK The Preferred Stock is issuable in one or more series or classes, any or all of which may have such voting powers, full or limited, or no voting powers, and such designations, preferences and related, participating, optional or other special rights and qualifications, limitations or restrictions thereof, as are set forth in the Company's Certificate of Incorporation, as amended, or in the resolution or resolutions providing for the issue of such stock adopted by the Board, which is expressly authorized to set such terms for any such issue. In November 1991, the Company issued 1,200,000 shares of $4.00 Exchangeable Convertible Preferred Stock, of which 1,186,005 shares were outstanding on December 31, 1993. Holders of such Preferred Stock are entitled to receive, when, as and if declared by the Board of Directors out of funds legally available therefor, cash dividends at an annual rate of $4.00 per share, payable quarterly in arrears. Upon liquidation, such holders are entitled to receive a preference of $50.00 per share, plus accrued and unpaid dividends to the payment date. Each share of such Preferred Stock is convertible into 5.51 shares of Common Stock at any time prior to redemption (subject to adjustment), equivalent to a conversion price of $9.07 for each share of Common Stock. The Company has the right to exchange the shares of such Preferred Stock for the Company's 8% Convertible Subordinated Debentures due 2006 on any dividend payment date and, subject to certain restrictions, the right to redeem such Preferred Stock beginning January 1, 1995. 38 13 In April 1993, the Company issued 1,035,000 shares (represented by 4,140,000 depositary shares) of $6.00 Exchangeable Convertible Preferred Stock, all of which were outstanding on December 31, 1993. Holders of such Preferred Stock are entitled to receive, when, as and if declared by the Board of Directors out of funds legally available therefor, cash dividends at an annual rate of $6.00 per share ($1.50 per depositary share), payable quarterly in arrears. Upon liquidation, such holders are entitled to receive a preference of $100.00 per share ($25.00 per depositary share), plus accrued and unpaid dividends to the payment date. Each share of such Preferred Stock is convertible into 4.762 shares of Common Stock at any time prior to redemption (subject to adjustment), equivalent to a conversion price of $21.00 for each share of Common Stock. The Company has the right to exchange the shares of such Preferred Stock for the Company's 6% Convertible Subordinated Debentures due 2008 on any dividend date payment on or after March 31, 1994 and the right to redeem such Preferred Stock beginning March 31, 1996. The existing series of Preferred Stock rank prior to the Common Stock, and on a parity with each other, as to dividends and upon liquidation, dissolution or winding up. FACTORS AFFECTING ACQUISITIONS OF CONTROL The Company's Certificate of Incorporation, as amended, provides that the Board of Directors, in its discretion, may establish one or more class or series of Preferred Stock having such number of shares, designations, relative voting rights, dividend rates, liquidation and other rights, preferences and limitations as may be fixed by the Board of Directors without any further stockholder approval. Such rights, preferences, privileges and limitations could have the effect of impeding or discouraging the acquisition of control of the Company. The Company is a Delaware corporation and is subject to Section 203 of the Delaware General Corporation Law (the "DGCL"). In general, Section 203 prevents an "interested stockholder" (defined generally as a person owning 15% or more of a corporation's outstanding voting stock) from engaging in a "business combination" (as defined) with a Delaware corporation for three years following the date such person became an interested stockholder unless (i) before such person became an interested stockholder, the board of directors of the corporation approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination; (ii) upon consummation of the transaction that resulted in the interested stockholder's becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding stock held by directors who are also officers of the corporation and by employee stock plans that do not provide employees with the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer); or (iii) following the transaction in which such person became an interested stockholder, the business combination is approved by the board of directors of the corporation and authorized at a meeting of stockholders by the affirmative vote of the holders of two-thirds of the outstanding voting stock of the corporation not owned by the interested stockholder. Under Section 203, the restrictions described above also do not apply to certain business combinations proposed by an interested stockholder following the announcement or notification of one of certain extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation's directors, if such extraordinary transaction is approved or not opposed by a majority of the directors who were directors prior to any person's becoming an interested stockholder during the previous three years or who were recommended for election or elected to succeed such directors by a majority of such directors. DIRECTORS' LIABILITY The Company's Certificate of Incorporation, as amended, also provides for the elimination of directors' liability for monetary damages for a breach of certain fiduciary duties and for the indemnification of directors, officers, employees or agents as permitted by the DGCL. These provisions cannot be amended without the affirmative vote of the holders of at least a majority in interest of the outstanding shares entitled to vote. 39 14 The Company has entered into indemnification agreements with all directors and executive officers and may, in the future, enter into such agreements with employees and agents. Such indemnification agreements provide generally that such persons will be indemnified, to the extent permitted by applicable law, for expenses (including attorneys' fees), judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by such persons in connection with any proceeding (including, to the extent permitted by law, any derivative action) to which such persons are, or are threatened to be made, a party by reason of their status in such positions. Such indemnification agreements do not change the basic legal standards for indemnity under applicable law or as set forth in the Certificate of Incorporation. 40
