                                   ARTICLE X
                      INDEMNIFICATION AND RELATED MATTERS

         10.1. Indemnification.

              (a) The Shareholder hereby agrees to indemnify and hold
Purchaser, its Affiliates and the officers, directors, employees, and agents
thereof, harmless (on an after-tax basis) from and against any and all claims,
judgments, causes of action, liabilities, obligations, damages, losses,
deficiencies, costs, penalties, interest, and expenses (including, without
limitation, the reasonable fees and expenses of counsel) (collectively,
"Losses") arising out of, based upon, attributable to, or resulting from:

                  (i) any inaccuracy of any representation, any breach of
         warranty or nonfulfillment of any agreement or covenant on the part of
         the Shareholder contained in this Agreement or any Seller Document;
         and

                  (ii) all claims, actions, suits, proceedings, investigations,
         demands, and assessments incident to any of the foregoing.

              (b) Purchaser hereby agrees to indemnify and hold the Shareholder
harmless (on an after-tax basis) from and against any and all Losses arising out
of, based upon, attributable to, or resulting from:

                  (i) any inaccuracy of any representation, any breach of
         warranty or nonfulfillment of any agreement or covenant on the part of
         Purchaser contained in this Agreement or any Purchaser Document; and

                  (ii) all claims, actions, suits, proceedings, investigations,
         demands, and assessments incident to the foregoing.

         Notwithstanding the foregoing provisions of Section 10.1(a)(ii) or
(b)(ii), the party entitled to indemnification ( the "Indemnified Party") shall
not be entitled to any claims for fees and expensed of counsel in respect of
any action, suit, or proceeding by the party from which indemnification is
sought (the "Indemnifying Party"), unless and until such action, suit, or
proceeding has been determined by a final, nonappealable order or judgment of a
court of competent jurisdiction in favor of such Indemnified Party.

         10.2. Procedures for Indemnification. Whenever a claim shall arise for
indemnification under Section 10.1, with the exception of claims for litigation
expenses in respect of litigation as to which a notice of claim, as provided in
this Section 10.2, has previously been given, which expenses shall be funded on
an ongoing basis, the Indemnified Party shall promptly notify Indemnifying
Party of such claim and, when known, the facts constituting the basis for such
claim; provided, however, that in the event of any claim for indemnification
hereunder resulting from or in connection with any claim or legal proceeding by
a third party, the Indemnified Party shall give such notice thereof to the
Indemnifying Party not later than ten business days prior to the time any
response to the asserted claim is required, if possible, and in any event
within five business days following receipt of notice thereof. Failure to give
timely notice or to include any specified information in any notice required by
this Section 10.2 will not effect the rights or obligations of any party
hereunder except and only to the extent that, as a result

                                      14

   15


of such failure, any party which was entitled to receive such notice was
deprived of its right to recover any payment under its applicable insurance
coverage or was otherwise damaged as a result of such failure. In the event of
any such claim for indemnification resulting from or in connection with a claim
or legal proceeding by a third party, the Indemnifying Party may, at its sole
cost and expense, assume the defense thereof using counsel who is reasonably
satisfactory to the Indemnified Party; provided, however, that the Indemnifying
Party shall first have agreed in writing that it does not and will not contest
its responsibility for indemnifying the Indemnified Party in respect of Losses
attributable to such claim or proceeding; and provided, however, that if the
defendants in any such actions include both the Indemnified Party and the
Indemnifying Party and the Indemnified Party shall have reasonably concluded
that there may be legal defenses or rights available to it which have not been
waived and are in actual or potential conflict with those available to the
Indemnifying Party, the Indemnified Party shall have the right to select one
law firm to act as separate counsel, on behalf of such Indemnified Party, at
the expense of the Indemnifying Party. Subject to the second proviso of the
immediately preceding sentence, if an Indemnifying Party assumes the defense of
any such claim or legal proceeding, the Indemnifying Party shall be entitled to
select counsel and take all steps necessary in the defense thereof; provided,
however, that no settlement shall be made without the prior written consent of
the Indemnified Party, which consent shall not be unreasonably withheld (and if
the Indemnified Party shall withhold its consent to any monetary settlement
proposed by the Indemnifying Party and which the other party to the action has
indicated it is prepared to accept, the Indemnified Party shall in no event be
deemed for purposes of this Agreement to have suffered Losses in connection
with such claim or proceeding in excess of the proposed amount of such
settlement); and provided, further, that subject to the second proviso of the
immediately preceding sentence, the Indemnified Party may, at its own expense,
participate in any such proceeding with the counsel of its choice without any
right of control thereof. So long as the Indemnifying Party is in good faith
defending such claim or proceeding, the Indemnified Party shall not compromise
or settle such claim without the prior written consent of the Indemnifying
Party, which consent shall not be unreasonably withheld. If the Indemnifying
Party does not assume the defense of any such claim or litigation in accordance
with the terms hereof, the Indemnified Party may defend against such claim or
litigation in such manner as it may deem appropriate, including, without
limitation, settling such claim or litigation (after giving prior written
notice of the same to the Indemnifying Party and obtaining the prior written
consent of the Indemnifying Party, which consent shall not be unreasonably
withheld) on such terms as the Indemnified Party may deem appropriate, and the
Indemnifying Party will promptly indemnify the Indemnified Party in accordance
with the provisions of this Section 10.2. Notwithstanding the foregoing, at any
time after the Indemnifying Party has failed to discharge its liability for
legal and other expenses pursuant to this Section 10.2, which failure shall not
have been cured, or at any time the Indemnifying Party is subject to a
bankruptcy case pursuant to Chapter 7 or Chapter 11 of the U.S. Bankruptcy
Code, if the Indemnified Party shall propose to settle a claim as to which it
intends to seek indemnity, it shall provide the Indemnifying Party with 21
days' written notice of such proposed settlement, and the Indemnifying Party
shall, within such period either (i) consent to the terms of the proposed
settlement or (ii) provide the Indemnified Party with (A) a written notice of
objection to the proposed settlement, with a statement of reason, (B)
reasonable evidence that the financial condition of the Indemnifying Party is
sufficient to permit it to pay a judgment for the full amount being sought by
the third party claimant (or, at the Indemnified Party's request, a letter of
credit in such amount) and (C) an undertaking to satisfy any such judgment.

                                  ARTICLE XI
                     RIGHT OF FIRST OFFER AND REIMBURSEMENT

         11.1. Right of First Offer.

              (a) If at any time after the Closing Date, the Shareholder
desires to transfer all or a portion of the shares of Stock owned by him to a
third party (other than an Affiliate or family member of the Shareholder and
other than as provided in the Warrant), the Shareholder shall give prompt
written notice (a "Notice of Offer") to the Company of his intent to transfer
the Stock, which notice shall contain the proposed sale price for the shares of
Stock being offered and the number of shares of Stock which the Shareholder
proposes to transfer and any other material term or condition of the proposed
transfer. The date on which such notice is sent to the Company is referred to
hereinafter as the "Notice Date." The Notice of Offer shall be deemed an
irrevocable offer to sell to the Company (or any Person designated by the
Company) such shares of Stock on the terms and conditions set forth in the
Notice of Offer. The Company shall have 15 days following the Notice Date to
notify in writing the Shareholder of its election to purchase all, but not less
than all, of such shares of Stock (or to have all, but not less than all, of
such shares of Stock purchased by its designees). If the Company notifies the
Shareholder of its election to purchase such shares of Stock, the closing for
such transaction shall take place no later than 30 days from the Notice Date.
If the Shareholder does not receive such written notice from the Company within
the 15-day period, the Company shall be deemed to have declined to purchase
such shares of Stock and the Shareholder may transfer such shares of Stock to
any third parties at not less than the sale price and upon the other terms and
conditions set forth in the Notice of Offer; provided, however, that if the
Shareholder does not complete the contemplated sale within 180 days of the
Notice Date, the provisions of this Section 11.1(a) shall again apply.

              (b) Notwithstanding anything herein to the contrary, the terms
and conditions of Section 11.1(a) do not apply to transfers made by the
Shareholder (i) pursuant to an effective registration statement or in the open
market pursuant to Rule 144 under the Securities Act or otherwise or (ii) in
connection with any merger or business combination of the Company approved by
the Board of Directors. 

         11.2. Reimbursement of the Company by the Shareholder.

              (a) In the event that each of the following conditions has been
satisfied: (i) a meeting of the shareholders of the Company to consider and
vote upon the approval of the Amendment (as defined in the Company Agreement)
shall have been duly convened and held; (ii) all of the Shares (as defined in
the Company Agreement) then issued and outstanding and the Shares acquired from
the Shareholder by Purchaser hereunder shall have been voted at such meeting in
favor of approval of the Amendment, (iii) there shall not have been in effect
as of the date of such meeting any Law or injunction or other order of any
Governmental Body restraining or preventing the Shareholder from voting any
shares of Stock as to which he possessed the power to vote in favor of approval
of the Amendment, and (iv) the Amendment shall not have been approved in
accordance with applicable Law and the Charter and By-laws of the Company, then
the Shareholder shall reimburse the Company for any amounts (but not to exceed
$1,000,000 in the aggregate) paid by the Company to Purchaser as liquidated
damages pursuant to Section 6.5 of the Company Agreement.

                                      16

   17


              (b) The Shareholder shall reimburse the Company for an amount
equal to 20% of (i) the fee of $1,000,000 to be paid by the Company to an
affiliate of Purchaser pursuant to Section 3(b) of the Financial Advisory
Agreement to be entered into between the Company and such affiliate upon the
Closing (as defined in the Company Agreement) and (ii) the fees and
disbursements of Cleary, Gottlieb, Steen & Hamilton.

                                  ARTICLE XII
                   REGISTRATION AND OTHER SHAREHOLDER RIGHTS

         12.1. Demand Registration.

              (a) Upon receipt by the Company at any time following the second
anniversary of the Closing Date of a written request from the Shareholder for
registration of the resale of any Registrable Shares, the Company shall use its
commercially reasonable efforts to cause a registration statement to be filed
under the Securities Act, and any other applicable Laws, within 60 days after
the receipt of such request. The Company shall use all commercially reasonable
efforts to cause any such registration statement to become effective and to
maintain the effectiveness of such registration statement until (x) the date
all Registrable Shares have been sold pursuant thereto or (y) 180 days after
the effective date of such registration statement. The term "registration
statement" means a registration statement filed under the Securities Act, or
any similar disclosure document, filing, or listing particulars utilized in
connection with a Public Equity Offering.

              (b) The Shareholder shall be permitted to make two requests
pursuant to the provisions of Section 12.1(a), provided that no request will be
(i) allowed unless the Company and the security offering shall at that time
satisfy the eligibility requirements for use of Form S-1 or any successor form
and (ii) counted against this limit unless, it has become effective and
remained effective for a period of at least 30 days; provided, however, that
if, within 180 days after it has become effective, an offering of Registrable
Shares pursuant to a registration is interfered with by any stop order,
injunction, or other order or requirement of the Commission or other
Governmental Body, such registration will be deemed not to have been effected
and will not count as a Demand Registration. A registration that is undertaken
by the Company in response to a valid request made by the Shareholder pursuant
to this Section 12.1 shall be referred to herein as a "Demand Registration."
Notwithstanding the foregoing provisions of this Section 12.1(b), the Company
shall not be required to register any Registrable Shares pursuant this Section
12.1(b) at any time (i) within 120 days of the effective date of any
registration statement filed as a result of the exercise of any demand
registration rights by the Shareholder or any other shareholder of the Company,
or (ii) in the event that the Company has registered shares of any class of its
capital stock pursuant to any demand registration rights on more than two
occasions in the preceding 12 months. 

              (c) The Company shall pay all registration expenses incurred with
respect to Section 12.1(a) (other than customary underwriting and broker
commissions), including, without limitation, the reasonable fees and
disbursements of one (but only one) legal firm or counsel to represent
Purchaser and the Shareholder in the case of a Demand Registration. 

              (d) The offering of Registrable Shares pursuant to a Demand
Registration shall be in the form of a "firm commitment" underwritten offering.
The Shareholder shall select the investment banking firm or firms to manage the
underwritten offering; provided, however, that such selection shall be subject
to the consent of the Company, which consent shall not be unreasonably withheld
or delayed. 

                                      17

   18


         12.2. Incidental or "Piggyback" Registration Rights.

              (a) If the Company or any holder of shares of Stock proposes to
sell shares of Stock in a Public Equity Offering, the Company shall give
written notice, at least 15 days prior to the filing of a registration
statement related to such Public Equity Offering (other than a registration
statement relating solely to employee benefit plans or to effect any
acquisition or combination with another Person), of such proposed Public Equity
Offering to the Shareholder which notice shall offer to the Shareholder and his
Affiliates the opportunity to include in such Public Equity Offering such
number of Registrable Shares as the Shareholder and his Affiliates may request.
Within 20 days after receipt of such notice, the Shareholder and his Affiliates
shall, subject to the following sentence, have the right by notifying the
Company in writing to require the Company to include in the registration
statement relating to such Public Equity Offering such number of Registrable
Shares as the Shareholder or his Affiliates may request. Notwithstanding the
foregoing, (x) if at any time the managing underwriter or underwriters of such
Public Equity Offering (the "Managing Underwriter") shall advise the Company in
writing that, in its opinion, the total number of shares proposed to be sold in
such Public Equity Offering (including the total number of Registrable Shares
that the Shareholder and his Affiliates have requested to be sold in such
Public Equity Offering and the total number of shares of Stock requested to be
included by any other selling shareholder entitled to sell shares in such
Public Equity Offering) exceeds the maximum number of shares which the Managing
Underwriter believes may be sold without materially adversely affecting the
price, timing, or distribution of the Public Equity Offering, then the Company
will be required to include in such Public Equity Offering only that number of
shares which the Managing Underwriter believes may be sold without causing such
adverse effect in the following order: (i) all the shares that the Company
proposes to sell in such Public Equity Offering, (ii) all the shares that are
proposed to be sold by any shareholder of the Company who is exercising a
demand registration right, if such Public Equity Offering is being made
pursuant to such demand, and (iii) shares of the Shareholder and his Affiliates
and all other shares that are proposed to be sold by any shareholder of the
Company exercising a so-called "piggyback" registration right on a pro rata
basis in an aggregate number which is equal to the difference between the
maximum number of shares that may be distributed in such Public Equity Offering
as determined by the Managing Underwriter and the number of shares to be sold
in such Public Equity Offering pursuant to clauses (i) and (ii) above, and (iv)
any other shares of Stock requested to be included in such Public Equity
Offering.

              (b) The Company will have the right to postpone or withdraw any

Section 12.2. 

         12.3. Suspension. In connection with any proposed registration of
Registrable Shares pursuant to Section 12.1 or 12.2, during any consecutive

60-consecutive-day periods if (i) at the time the Company receives a request

Registration, the Company or any Subsidiary is engaged in confidential
negotiations or other confidential business activities, disclosure of which
would be required in such registration statement (but would not be required if
such registration statement were not filed), and the Board of Directors
determines in good faith that such disclosure would be materially detrimental
to the Company and its shareholders or would have a material adverse effect on
any such confidential negotiations or other confidential business activities,
(ii) prior to receiving such request, the Board of Directors were to have
determined to effect a Public Equity Offering for the Company's account and the
Company had taken substantial steps (including, but not limited to, selecting a
managing underwriter for such offering) and is proceeding with reasonable
diligence to effect such offering, or (iii) the Company shall furnish to
Purchaser a certificate signed by the President of the Company stating that in
the good faith judgment of the Board of Directors it would be seriously
detrimental to the Company and its shareholders for such registration to be
pursued at such time; provided, however, that any suspension under clause (iii)
shall not exceed 60 days.

         12.4. Preparation and Filing.

              (a) Whenever the Company seeks to effect the registration of any
Registrable Shares in accordance with the provisions of Section 12.1 or 12.2,
the Company shall:

         Section 12.3, remain effective for the period set forth in subsection
         (ii) below and promptly notify the Shareholder (x) when such
         registration statement becomes effective, (y) when any amendment to
         such registration statement becomes effective and (z) of any request
         by the Commission or other applicable Governmental Body for any
         amendment or supplement to such registration statement or any
         prospectus relating thereto or for additional information;

                  (ii) prepare and file with the Commission or other applicable
         Governmental Body such amendments and supplements to such registration
         statement and the prospectus used in connection therewith as may be
         necessary to keep such registration statement effective and to comply
         with the provisions of the Securities Act, and any other applicable
         Laws, with respect to the sale or other disposition of all securities
         covered by such registration statement for a period of not less than
         180 days after the effective date of such registration statement (or
         such shorter period to the extent necessary to permit the completion
         of the sale or distribution of such securities within such period);

                  (iii) furnish to the Shareholder, prior to filing a
         registration statement, copies of such registration statement as
         proposed to be filed and thereafter, such number of copies of such
         registration statement, each amendment and supplement thereto, the
         prospectus included in such registration statement (including each
         preliminary prospectus) and financial statements, reports, and proxy
         statements mailed to shareholders of the Company as the Shareholder
         may reasonably request in order to facilitate the disposition of the
         Registrable Shares being sold; 

                  (iv) use its commercially reasonable efforts to register or
         qualify, not later than the effective date of any filed registration
         statement, the Registrable Shares 

                                      19

   20

         covered by such registration statement under the securities or "blue
         sky" laws of such jurisdictions as the Shareholder reasonably
         requests; provided, however, that the Company will not be required to
         (A) qualify to do business as a foreign corporation or as a dealer in
         any jurisdiction where it is not so qualified, (B) subject itself to
         taxation in any jurisdiction where it is not subject to taxation, (C)
         consent to general service of process in any jurisdiction where it is
         not subject to general service of process, or (D) take any action that
         would subject it to service of process in suits other than those
         arising out of the offer or sale of the Registrable Shares covered by
         the registration statement; 

                  (v) make available, upon reasonable notice and during
         business hours, for inspection by the managing underwriter(s) for the
         Registrable Shares (and one counsel representing such managing
         underwriter(s)) (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents, agreements, and
         properties of the Company and its Subsidiaries and Affiliates as shall
         be reasonably necessary to enable them to exercise their due diligence
         responsibilities ("Records") and cause the Company's officers,
         directors, and employees to supply all information reasonably
         requested by any such Inspectors in connection with the registration
         statement; provided, however, that, unless the disclosure of such
         Records is necessary to avoid or correct a misstatement or omission in
         the registration statement or the release of such Records is ordered
         pursuant to a subpoena or other order from a court of competent
         jurisdiction, the Company shall not be required to provide any
         information under this subparagraph (v) if (A) the Company believes,
         after consultation with counsel for the Company, that to do so would
         cause the Company to forfeit an attorney-client privilege that was
         applicable to such information or (B) if either (1) the Company has
         requested and been granted from the Commission confidential treatment
         of such information contained in any filing with the Commission or
         documents provided supplementally or otherwise or (2) the Company
         reasonably determines in good faith that such Records are confidential
         and so notifies the Inspectors in writing unless prior to furnishing
         any such information with respect to (A) or (B) such holder of
         Registrable Shares requesting such information agrees to enter into a
         confidentiality agreement in a form reasonably acceptable to the
         Company; and, provided, further, that each holder of Registrable
         Shares agrees that it will, upon learning that disclosure of such
         Records is sought in a court of competent jurisdiction, give prompt
         notice to the Company and allow the Company, at its expense, to
         undertake appropriate action and to prevent disclosure of the Records
         deemed confidential; 

                  (vi) obtain a comfort letter from the Company's independent
         public accountants dated within five business days prior to the
         effective date of the registration statement (and as of such other
         dates as the managing underwriter(s) for the Registrable Shares may
         reasonably request) in customary form and covering such matters of the
         type customarily covered by such comfort letters as such managing
         underwriter(s) reasonably request;

                  (vii) obtain an opinion of counsel dated the effective date
         of the registration statement (and as of such other dates as the
         managing underwriter(s) for the Registrable Shares may reasonably
         request) in customary form and covering such matters of the type
         customarily covered by such opinions as counsel designated by such
         managing underwriter(s) reasonably request; 

                                      20

   21


                  (viii) during the period when the registration statement is
         required to be effective, notify the Shareholder of the happening of
         any event as a result of which the prospectus included in the
         registration statement contains an untrue statement of a material fact
         or omits to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading, and the
         Company will forthwith prepare a supplement or amendment to such
         prospectus so that, as thereafter delivered to the purchasers of such
         Registrable Shares, such prospectus will not contain an untrue
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading;

                  (ix) in the case of an underwritten offering, enter into an
         underwriting agreement containing customary terms, including such
         indemnity and contribution provisions as the managing underwriter(s)
         customarily require or may reasonably require;

                  (x) cause such Registrable Shares to be listed for trading on
         the primary securities exchange or quotation system upon which the
         Stock is then listed or traded; and

                  (xi) otherwise use its commercially reasonable efforts to
         comply with all applicable rules and regulations of the Commission,
         and other applicable Governmental Bodies, and make available to its
         security holders, as soon as reasonably practicable, an earnings
         statement covering a period of 12 months, beginning within three
         months after the effective date of the registration statement, which
         earnings statement shall satisfy the provisions of Section 11(a) of
         the Securities Act. 


              (b) The Shareholder shall timely furnish to the Company such
information (including affidavits) regarding the distribution of such
Registrable Shares as the Company may from time to time reasonably request. The
Company may exclude from such registration the securities of the Shareholder or
his Affiliates if he or they fail to furnish such information within 10 days
after such request; provided, however, that the Company's registration
statement relating to such offering is effective within 60 days after the
expiration of such 10-day period.

              (c) The Shareholder agrees that upon the receipt of any notice
from the Company of the happening of any event of the kind described in
paragraph (a)(viii) above, it will forthwith discontinue disposition of
Registrable Shares pursuant to the registration statement covering such
Registrable Shares until the Shareholder's receipt of the copies of the
supplemented or amended prospectus contemplated by paragraph (a)(viii) above.
If the Company gives any such notice, the Company shall keep any such
registration statement pursuant to a Demand Registration effective for that
number of additional days equal to the number of days during the period from
and including the date of the giving of such notice pursuant to paragraph
(a)(viii) above to and including the date on which copies of such supplemented
or amended prospectus are made available to the Shareholder. 

         12.5. Indemnification. In connection with the filing of a registration
statement providing for the registration of any Registrable Shares pursuant to
Section 12.1 or 12.2, the Company shall indemnify and hold harmless the
Shareholder and his Affiliates, to the extent customary and reasonable,
pursuant to indemnification and contribution provisions to be entered into by
the Company at the time of filing of such registration statement. The
Shareholder and his 

                                      21

   22


Affiliates shall indemnify the Company and its directors and officers and each
Person who controls the Company (within the meaning of the Securities Act or
the Exchange Act) against any and all Losses resulting from any untrue
statement or alleged untrue statement of a material fact contained in the
registration statement, prospectus, or any preliminary prospectus or any
amendment thereof or supplement thereto or any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is made
in reliance upon and in strict conformity with information furnished in writing
to the Company by Shareholder for use in such registration statement; provided,
however, that the obligation to indemnify will be several and not joint and
several, among such sellers of Registrable Shares, and the liability of each
such seller of Registrable Shares will be in proportion to, and provided
further that such liability will be limited to, the net amount received by such
seller from the sale of Registrable Shares pursuant to such registration
statement; further provided, that such seller of Registrable Shares shall not
be liable in any such case to the extent that prior to the filing of any such
registration statement or prospectus or amendment thereof or supplement
thereto, such seller has furnished in writing to the Company information
expressly for use in such registration statement or prospectus or amendment
thereof or supplement thereto which corrected or made not misleading
information previously furnished to the Company.

Term of Warrant.

         (a) Ownership. Shareholder may deem and treat the Person in whose name
this Warrant is registered as the Holder and owner hereof for all purposes,
notwithstanding any notations of ownership or writing hereon made by anyone
other than Shareholder, and shall not be affected by any notice to the contrary,
until presentation of this Warrant for registration of transfer as provided in

Shareholder, at its office or agency in Fort Worth, Texas (or at such other

by notice to Shareholder and the registered Holder of this Warrant), a register
for the Warrants, in which the Company shall record the name and address of the
Person in whose name each Warrant has been issued, as well as the name and
address of each transferee and each prior owner of such Warrant. Within five (5)

Holder, as such information appears in such register at the close of business on

         (b) Escrow. Concurrently with the execution hereof, Shareholder is

representing all of the shares 



                                       3
   31

of Common Stock deliverable upon exercise of this Warrant on the date hereof,
such shares to be held in escrow by the Company for the benefit of Holder upon
exercise of this Warrant. Shareholder agrees and covenants (i) that he will take
no action, nor willfully permit any action to be taken, that would result in any
Lien being placed on the shares of Common Stock so placed in escrow and (ii)
that he will forthwith deliver to the Company, upon request of the Company or
the Holder, any shares of Common Stock that become subject to this Warrant in
the future as a result of adjustments pursuant to Section 5 hereof, free and
clear of any Lien. Shareholder authorizes the Company, or, at any time that
Company uses a stock transfer agent, the Company's transfer agent, to place a
stop transfer legend on the stock transfer records of the Company in respect of
such shares of Common Stock until the earlier of (i) the exercise of this
Warrant with respect to such shares of Common Stock or (ii) the expiration or
cancellation hereof. Shareholder hereby authorizes the Company to act in his
place and stead in delivering Warrant Shares upon exercise of this Warrant and
authorizes the Company to accept payment of the Purchase Price on Shareholder's
behalf upon exercise, or partial exercise, of this Warrant. The Company agrees
to promptly pay over to Shareholder such Purchase Price. 

         (c) Term. This Warrant shall be void after 5:00 p.m. Eastern Standard
time on the Expiration Date. To the extent that this Warrant, or any portion
hereof, has not been exercised before 5:00 p.m. Eastern Standard time on the
Expiration Date, all shares of Common Stock held pursuant hereto will be
immediately released to Shareholder and the Company will remove, or cause to be
removed, all stop transfer legends placed thereon as a result of such escrow.

         (d) No Rights as Shareholder. Notwithstanding the foregoing, nothing in
this Warrant shall be construed as conferring upon the Holder or its transferees
any rights as a shareholder of the Company, including the right to vote, receive
dividends, consent or receive notices as shareholder with respect to any meeting
of shareholders for the election of directors of the Company or any other
matter. Shareholder shall retain all rights as a shareholder of the Company with
respect to the Escrow Shares including any right to vote for the election of
directors or upon any matter submitted to shareholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, or change of stock to no par value, consolidation, merger conveyance, or
otherwise) or to receive notice of meeting, and except as otherwise provided for
herein receive dividends or subscription rights or otherwise until the Warrant
shall have been exercised as provided herein. 

         Section 3. Exchange, Transfer and Replacement.

         (a) Exchange. This Warrant is exchangeable, upon the surrender hereof
by the registered Holder to Shareholder at the Company's office or agency
provided for in Section 2, for new Warrants of like tenor, representing in the
aggregate the right to purchase the number of shares of the Common Stock
purchasable hereunder or under any other Warrants tendered herewith, each of
such new Warrants to represent the right to purchase such number of shares of
the Common Stock as shall be designated by said registered Holder at the time of
such surrender, not to exceed the aggregate shares of Common Stock purchasable
on the exercise of all such tendered Warrants.

         (b) Transfer. This Warrant and all rights hereunder are transferable,
in whole or in part, but only upon the register provided for in Section 2 and
only upon satisfaction of the conditions set forth in this Warrant, by the
registered Holder hereof, and a new Warrant shall be made and delivered by the
Company on behalf of Shareholder, of the same tenor as this Warrant but
registered in the name of the transferee, upon surrender of this Warrant with
the assignment 


                                       4
   32

form attached hereto duly completed, at said office or agency of the Company. No
sale, transfer, or other disposition of this Warrant or the Warrant Shares
issuable hereunder will be made without registration under the Securities Act
and applicable state securities laws or pursuant to exemptions therefrom. The
Company or Shareholder may, as a condition to any such transfer, require an
opinion of counsel reasonably satisfactory to it that such transfer complies
with all applicable federal and state securities laws.

         (c) Replacement. Upon receipt by Shareholder at the Company's office or
agency provided for in Section 2 of evidence reasonably satisfactory to
Shareholder of the loss, theft, destruction or mutilation of this Warrant, and,
in the case of loss, theft, or destruction, of indemnity or security reasonably
satisfactory to Shareholder and the Company, and upon surrender of this Warrant,
if mutilated, the Company on behalf of Shareholder will make and deliver a new
Warrant of like tenor, in replacement of this Warrant; provided that, if Wingate
or any of its Affiliates shall be the registered Holder hereof, an agreement of
indemnity (in form reasonably satisfactory to Shareholder) by such registered
Holder shall be sufficient for all purposes of this Section 3.

         (d) Cancellation and Taxes. This Warrant shall be promptly cancelled by
Shareholder upon the surrender hereof in connection with any exchange, transfer,
or replacement pursuant to this Section 3.

         (e) Legend. All Warrants issued upon transfer hereof, including all
amendments to any such Warrants shall be imprinted with a legend in
substantially the following form (in addition to any legend required by state

             THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS
WARRANT WERE PURCHASED PURSUANT TO A STOCK PURCHASE AGREEMENT DATED DECEMBER 23,

THIS WARRANT NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE BEEN

ACT"), OR ANY STATE SECURITIES LAW, AND SUCH SECURITIES MAY NOT BE OFFERED,

PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR PURSUANT TO AN EXEMPTION
FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAW AND SECTION 3 OF THIS
WARRANT.

         Section 4. Exercise of this Warrant.

         (a) In order to exercise this Warrant in whole or in part, the
registered Holder hereof shall complete a subscription form in the form attached
hereto and deliver to Shareholder at the Company's office or agency provided for
in Section 2 such subscription form, this Warrant and the aggregate Purchase
Price of the shares of the Common Stock then being purchased; provided that any
single exercise of this Warrant not made in whole must be for a minimum of 5,000
Warrant Shares as adjusted pursuant to Section 6.

         (b) Such Purchase Price shall be paid to Shareholder in lawful money of
the United States by company check of Wingate or an Affiliate of Wingate, or, if
the Holder is other than Wingate or an Affiliate of Wingate, by certified check
drawn on a banking institution chartered by the government of the United States
or any state thereof or wire transfer of funds.


                                       5
   33

         (c) The exercise of this Warrant shall be deemed to have been effected
and the Purchase Price and the number of shares of the Common Stock issuable in
connection with such exercise shall be determined as of the close of business on
the Business Day on which the last to be delivered of such completed
subscription form and all other items required to be delivered in connection
with such exercise by the registered Holder hereof pursuant to this Section 4
shall have been delivered to the Company on behalf of Shareholder at the
requisite office or agency of the Company. Upon receipt of such form and other
items, the Company shall, as promptly as practicable, and in any event within
five (5) Business Days thereafter, deliver from escrow such shares of Common
Stock as shall be specified on such form and for which the Purchase Price has
been tendered. The Company hereby undertakes to prepare a new certificate or
certificates, in such number of shares as is requested by Holder, and deliver
such certificate(s) representing the number of shares of Common Stock to be
received upon exercise hereof. To the extent that this Warrant is exercised only
in part, Shareholder agrees to execute and deliver a new Warrant of like tenor
to Holder for the purchase of the remaining shares subject to this Warrant.

         Section 5. Payment of Taxes. The Company shall pay any and all
documentary, stamp or similar issue or transfer taxes and other governmental
charges that may be imposed under the laws of the United States of America or
any political subdivision or taxing authority thereof or therein in respect of
any issue or delivery of Warrant Shares or of other securities or property
deliverable upon exercise of the Warrants evidenced by this Warrant representing
such shares or securities (other than income taxes imposed on Holders); provided
that the Company shall not be required to pay any such tax or other charge that
may be imposed in connection with any transfer involved in the issue of any
certificate for Warrant Shares or other securities or property, or payment of
cash, to any Person other than the Holder who surrendered a Warrant upon
exercise, and in case of any such tax or charge, the Company shall not be
required to issue any security or property or pay any cash until such tax or
charge has been paid or it has been established to the Company's satisfaction
that no such tax or charge is payable.

         Section 6. Share Adjustment Provisions; Adjustment of Purchase Price.
The Purchase Price from time to time in effect under this Warrant, and the
number of Warrant Shares subject to purchase hereunder, shall be subject to
adjustments from time to time as hereinafter set forth in this section.

         (a) Common Stock Splits. Upon any subdivision by the Company on or
after the Initial Issue Date of all of its outstanding shares of Common Stock
into a greater number of shares or upon any issuance by the Company on or after
such date of a greater number of shares of Common Stock in a pro rata exchange
for all of its outstanding shares of Common Stock, then in each case from and
after the record date for such subdivision or exchange the number of Warrant
Shares purchasable upon the exercise of this Warrant shall be increased in
proportion to such increase in the number of outstanding shares of Common Stock,
and the Purchase Price then in effect shall be correspondingly decreased. Upon
any pro rata reduction by the Company on or after the Initial Issue Date of its
outstanding shares of Common Stock as a whole or upon any issuance by the
Company after such date of a lesser number of shares of Common Stock in a pro
rata exchange for all of its outstanding shares of Common Stock, then in each
case from and after the record date for such reduction or exchange the number of
Warrant Shares purchasable upon the exercise of this Warrant shall be decreased
in proportion to such reduction in the number of outstanding shares of Common
Stock, and the Purchase Price then in effect shall be correspondingly increased.

         (b) Common Stock Dividends. Upon any declaration and payment by the
Company on or after the Initial Issue Date of a dividend upon Common Stock
payable in Common Stock, 



                                       6
   34

then in each case from and after the payment of such stock dividend, the number
of Warrant Shares purchasable upon the exercise of this Warrant shall be
increased in proportion to the increase in the number of outstanding shares of
Common Stock through such stock dividend, and the Purchase Price then in effect
shall be correspondingly decreased.

         (c) Other Issues. Upon any issuance by the Company to the Shareholder
or his Affiliates or family members (the "Shareholder Group") of shares of
Common Stock on or after the Initial Issue Date (other than issuances of stock
requiring adjustments hereunder pursuant to the immediately preceding
subsections (a) and (b) of this Section 6) for a consideration lower than the
Market Price per share of stock in effect immediately prior to such issuance,
the Purchase Price then in effect shall be reduced or increased, as appropriate,
to equal the following amount:

                           (D x E) + (F x G)
                           -----------------
                                   C x E

where C equals the number of shares of Common Stock beneficially owned by the
Shareholder Group immediately after such additional issuance, D equals the
number of shares of Common Stock beneficially owned by the Shareholder Group
prior to the issue of such additional Common Stock, E equals the Market Price
per share of stock in effect immediately prior to the issue of such additional
Common Stock, F equals the aggregate consideration (before deducting
underwriting discounts, commissions, and other expenses) received or to be
received by the Company in connection with the issuance of such additional
Common Stock, and G equals the Purchase Price which would have been in effect
immediately prior to such issuance had all previous adjustments (if any) under
this subsection (c) been made pursuant to the foregoing formula. Upon any such
reduction in the Purchase Price, the number of Warrant Shares purchasable upon
the exercise of this Warrant shall be correspondingly increased. The provisions
of this subsection (c) shall not be applicable to any issuance of Common Stock
upon actual exercise or actual conversion of any option, warrant, right, or
other security convertible into or exercisable for Common Stock if the Purchase
Price was fully and properly adjusted pursuant to the immediately following
subsection (d) at the time such option, warrant, right, or other security was
issued.

         (d) Common Stock Options; Subscription Rights; Convertible Securities.
Upon any issuance by the Company to any member of the Shareholder Group on or
after the Initial Issue Date of options or rights to subscribe for shares of
Common Stock or of any securities convertible into or exchangeable for shares of
Common Stock or of any similar securities for a consideration per share less
than the Market Price in effect immediately prior to the issuance of such
options, rights, or securities, the Purchase Price shall be reduced (and the
number of shares of Common Stock purchasable upon the exercise of this Warrant
shall be appropriately increased or reduced), by making computations in
accordance with subsection (c) of this Section 6; provided that:

             (i) The maximum number of shares of Common Stock deliverable under
         any such option or right shall be considered to have been delivered at
         the time such option or right was issued, for a consideration equal to
         the minimum purchase price per share of Common Stock provided for in
         such option or right, plus the consideration, if any, received by the
         Company for such option or right (before deducting underwriting
         discounts, commissions, and other expenses);

             (ii) The aggregate maximum number of shares of Common Stock
         deliverable upon conversion of or exchange for any such securities
         shall be considered to have been 


                                       7
   35

         delivered at the time of issuance of such securities, for a
         consideration equal to the consideration received by the Company for
         such securities (before deducting underwriting discounts, commissions,
         and other expenses) plus the minimum consideration (other than such
         securities) to be received by the Company upon the exchange or
         conversion of such securities; 

             (iii) If the purchase or conversion price provided for in any
         rights or options referred to above, the additional consideration, if
         any, payable upon the conversion or exchange of convertible securities
         referred to above, or the rate at which any convertible securities
         referred to above are convertible into or exchangeable for shares of
         Common Stock shall change (other than under or by reason of provisions
         designed to protect against dilution), the Purchase Price (and the
         number of shares of Common Stock purchasable upon the exercise of this
         Warrant) in effect at the time of such event shall be readjusted to the
         Purchase Price (and the number of shares of Common Stock purchasable
         upon the exercise of this Warrant) which would have been in effect at
         such time had such rights, options, or convertible securities still
         outstanding provided for such new purchase or conversion price,
         additional consideration, or conversion rate, as the case may be, at
         the time initially granted, issued, or sold. If the purchase or
         conversion price provided for in any such right or option referred to
         above, the additional consideration, if any, payable upon the
         conversion or exchange of convertible securities referred to above, or
         the rate at which any convertible securities referred to above are
         convertible into or exchangeable for shares of Common Stock shall be
         changed at any time by reason of provisions designed to protect against
         dilution, then when shares of Common Stock are delivered upon the
         exercise of any such right or option or upon conversion or exchange of
         any such convertible security, the Purchase Price (and the number of
         shares of Common Stock purchasable upon the exercise of this Warrant)
         then in effect hereunder shall be readjusted to such amount as would
         have been obtained had such right, option, or convertible security
         never been issued as to such shares of Common Stock and had the
         adjustments required hereunder been made at the time of the issuance of
         the shares of Common Stock delivered as aforesaid; and

             (iv) On the expiration of any such options or rights, or at the
         termination of any such rights to convert or exchange, the Purchase
         Price (and the number of shares of Common Stock purchasable upon the
         exercise of this Warrant) then in effect shall be readjusted to the
         Purchase Price (and the number of shares of Common Stock purchasable
         upon the exercise of this Warrant) which would have been in effect had
         the adjustments (and readjustments) made upon the issuance of such
         expired or terminated options, rights, or securities (or upon the
         occurrence of any event with respect thereto specified in the
         immediately preceding subsection (iii)) not been made. Notwithstanding
         the prior sentence, the Holder shall not be required to surrender or
         adjust any shares of Common Stock theretofore received by the Holder
         upon exercise of a Warrant. 

         (e) Special Dividends; Purchase Rights.

             (i) If at any time on or after the Initial Issue Date the Company
         shall distribute to all holders of shares of Common Stock of any class
         evidences of its indebtedness or assets (excluding any regular periodic
         cash dividend) or a distribution in partial liquidation, each payable
         otherwise than in shares of Common Stock or in securities to which the
         provisions of the immediately following subsection (e)(ii) are
         applicable, Shareholder shall pay to the Holder of this Warrant, upon
         the exercise hereof at any time on or after the payment of such
         dividend or distribution, the securities and 


                                       8
   36

         other property (including cash) which such Holder would have received
         (together with all subsequent distributions thereon) if such Holder had
         exercised or converted this Warrant on the record date fixed in
         connection with such dividend or distribution, and Shareholder shall
         take whatever steps are necessary or appropriate to keep available at
         all times any securities and other properties which are required to
         fulfill such obligations of Shareholder. Notwithstanding the foregoing,
         the rights of the Holder hereof under this subsection (e)(i) upon the
         Company's declaration of a dividend or distribution in partial
         liquidation payable only in securities convertible into shares of
         Common Stock may be exercised only in lieu of any adjustment (in this
         subsection (e) called a "subsection (d) adjustment") because of such
         dividend or distribution called for under subsection (d) of this
         Section 6, and upon exercise hereof such Holder must elect (as
         indicated in the subscription form attached hereto) either such
         subsection (d) adjustment or the rights and benefits provided for in
         this subsection (e)(i). Upon the election by Holder of rights under
         this subsection (e)(i), and delivery of the subscription form to
         Shareholder, Shareholder shall exercise such rights on behalf of Holder
         and deliver to Holder certificates for any Common Stock so received,
         originally executed for transfer to Holder promptly upon receipt
         thereof from the Company. For the purposes of determining the Purchase
         Price from time to time in effect and the number of shares from time to
         time subject hereto prior to the exercise hereof, it shall be assumed
         that the Holder hereof will so elect subsection (d) adjustments, but
         upon any election of the rights and benefits provided for in this
         subsection (e)(i) made at the time of exercise hereof the Purchase
         Price then in effect (and the number of outstanding shares of Common
         Stock purchasable upon such exercise) shall be redetermined to equal
         the amounts which would have been in effect had such subsection (d)
         adjustments never been made. Notwithstanding the provisions of this
         subsection (e)(i), in no event shall any Holder have the right to, or
         the right to elect to, receive Common Stock pursuant to this Warrant
         if, as a result thereof, a "change of control" could be deemed to occur
         under that certain Indenture dated as of December 1, 1997, by and among
         the Company, the Subsidiary Guarantors (as defined therein) and United
         States Trust Company of New York, as Trustee, and, in lieu thereof, the
         Holder shall have the right to receive, or the right to elect to
         receive, Nonvoting Common Stock. Shareholder hereby undertakes to
         deliver or cause to be delivered to the Company shares of Common Stock
         in equivalent number to any shares of Nonvoting Common Stock
         deliverable pursuant to this provision. The Company hereby undertakes
         to deliver to Holder, upon receipt of such Common Stock from
         Shareholder (which shall include any shares held in escrow) such shares
         of Nonvoting Common Stock.

             (ii) If at any time on or after the date hereof the Company shall
         grant, issue or sell any options or rights to purchase stock, warrants,
         securities or other property pro rata to the holders of Common Stock of
         all classes ("Purchase Rights"), then each Holder shall be entitled
         (but not obligated) to acquire from Shareholder upon 10 days notice and
         subject to advance payment to Shareholder of the consideration, costs
         and expenses, if any, related to the Purchase Rights, in lieu of any
         subsection (d) adjustment and upon the terms applicable to such
         Purchase Rights, the aggregate Purchase Rights which such Holder could
         have acquired if it had held the number of shares of Common Stock
         purchasable upon exercise of the Warrants immediately prior to the time
         or times at which the Company granted, issued or sold such Purchase
         Rights.

         (f) Effect of Reorganization and Asset Sales. If any capital
reorganization of the Company, reclassification of the capital stock of the
Company, statutory exchange, consolidation or merger of the Company with another
Person, or sale of all or substantially all of the Company's assets to another
Person shall be effected in such a way that holders of Common Stock shall be


                                       9
   37


entitled to receive stock, securities or assets (including cash) of the Company
or another Person with respect to or in exchange for Common Stock (each such
transaction being hereinafter referred to as a "Transaction"), then each Holder
shall be entitled to receive, and such Warrants shall thereafter represent the
right to receive, in lieu of the Common Stock issuable upon such exercise or
conversion but otherwise upon and subject to all terms and conditions hereof,
the cash, securities or other property to which such Holder would have been
entitled upon the consummation of such Transaction if such Holder had exercised
or converted such Warrants immediately prior thereto (subject to adjustments
from and after the consummation date of such Transactions as nearly equivalent
as possible to the adjustments provided for in this Section 6).

         (g) Notice of Adjustment or Substitution. On the happening of an event
requiring an adjustment of the Purchase Price and upon each change in the number
of Warrant Shares issuable upon the exercise of this Warrant, and in the event
of any change in the rights of the Holder of this Warrant by reason of other
events herein set forth, the Company shall, on behalf of Shareholder,
immediately give written notice to the registered Holder(s) of this Warrant: (i)
describing the event; (ii) stating the adjusted Purchase Price, the number of
Warrant Shares issuable upon exercise or change in rights; and (iii) stating how
such adjustment of Purchase Price or number of Warrant Shares was calculated and
the facts on which the calculation is based.

         (h) Adjustment Exceptions. Anything in this Section 6 to the contrary
notwithstanding, no adjustment of the Purchase Price or the number of Warrant
Shares issuable upon the exercise of this Warrant shall be made upon (a) the
issuance of any Warrants, (b) the issuance of any Warrant Shares, and (c) the
issuance of any shares of Common Stock or (d) other options or rights to
purchase stock, warrants, other securities to any member of the Shareholder
Group who is an employee of the Company pursuant to a plan established by the
Company for the exclusive benefit of its employees. Furthermore, none of the
securities issued as described in this subsection (h) shall be deemed to be
outstanding for the purposes of making the adjustments required by Section 6(c).

         (i) Company Undertakings. The Company hereby agrees to withhold from
any dividend, distribution, right, securities or property otherwise receivable
by the Shareholder as a result of any stock split, recapitalization,
reorganization, statutory exchange, Transaction, Purchase Right or like event,
such portion of the securities and other property (including cash) otherwise
payable to Shareholder as a result of his record ownership of the Warrant Shares
subject to this Warrant and to hold such securities and property in escrow for
the benefit of the Holder upon exercise of this Warrant; provided, however, that
the Company shall not be required to withhold any Purchase Right to the extent
that such Purchase Right expires prior to the Expiration Date and shall, in lieu
thereof, provide notice in accordance with Section 7 hereof.

         Section 7. Notifications by the Company. If at any time:

         (a) the Company shall declare upon the Common Stock any dividend or
other distribution to the holders of the Common Stock;

         (b) the Company shall make an offer for subscription pro rata to the
holders of the Common Stock of any additional shares of stock of any class or
other rights whether by Purchase Rights or otherwise;

         (c) the Board of Directors of the Company shall authorize (whether
definitively or subject to any conditions) any capital reorganization of the
Company, any statutory exchange, 



                                       10
   38

any reclassification of the capital stock of the Company, or any consolidation
of the Company or merger of the Company with, or sale of all or substantially
all of its assets to, another Person;

         (d) the Board of Directors of the Company shall authorize (whether
definitively or subject to any conditions) a voluntary dissolution, liquidation
or winding-up of the Company; or

         (e) the Company shall become subject to involuntary dissolution,
liquidation or winding-up;

then, in any one or more of such cases, the Company, on behalf of the
Shareholder shall give notice thereof to each registered Holder of Warrants,
specifying (i) the date on which the books of the Company shall close or a
record shall be taken for such dividend, distribution or subscription rights or
(ii) the date on which such reorganization, reclassification, statutory
exchange, consolidation, merger, sale, dissolution, liquidation or winding-up
shall take place or be voted upon by shareholders of the Company, as the case
may be. Any such notice under subsections (a) through (e) of this section shall
also specify the date as of which the holders of record of the Common Stock
shall participate in such dividend, distribution or subscription rights, or
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding-up, as the case may be; such
notice shall be given not less than thirty (30) and not more than fifty (50)
days prior to the action in question (except in the case of notice for actions
under Section 7(e), which notice shall be promptly following such action) and
not less than thirty (30) and not more than fifty (50) days prior to the record
date or the date on which the Company's transfer books are closed in respect
thereto, and such notice shall state that the action in question or the record
date is subject to the effectiveness of a registration statement under the
Securities Act or to a favorable vote of stockholders, if either is required.

         Section 8. Notices. All notices, requests and other communications
required or permitted to be given or delivered to registered Holders shall be in
writing, and shall be delivered, or shall be sent by certified or registered
mail, postage prepaid and addressed, to each such Holder at the address shown on
such Holder's Warrant, or at such other address as shall have been furnished to
the Company by notice from such Holder. All notices, requests and other

right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, change of par value, or change of stock to no par
value, consolidation, merger conveyance, or otherwise) or to receive notice of
meetings, (except as otherwise provided for herein) receive dividends or
subscription rights or otherwise until the Warrant shall have been exercised as
provided herein. No provision hereof, in the absence of affirmative action by
the Holder hereof to purchase shares of the Common Stock, and no mere
enumeration herein of the rights or privileges of the Holder hereof, shall give
rise to any liability of such Holder for the Purchase Price or as a shareholder
of the Company, whether such liability is asserted by the Company or by
creditors of the Company.

         Section 10. Governing Law. This Warrant shall be construed in
accordance with and governed by the laws of the State of Texas, without regard
to the provisions thereof relating to conflict of laws. 

         Section 11. Confidentiality. By its acceptance hereof each Holder of
this Warrant agrees that it will take all reasonable steps to keep confidential
any proprietary information of the Company furnished to it, provided, however,
that this restriction shall not apply to information which (i) has at the time
in question entered the public domain, (ii) is required to be disclosed by law
or by any order, rule or regulation (whether valid or invalid) of any
Governmental Body, or (iii) is furnished to purchasers or prospective purchasers
hereof (exclusive of any Person who 


                                       12
   40

competes with, or is an Affiliate of a Person who competes with, the Company) so
long as such purchasers and prospective purchasers have agreed to be subject to
restrictions identical to those imposed upon such Holder under this sentence.

         Section 12. Miscellaneous. Unless otherwise expressly provided herein
or unless the registered Holder hereof otherwise consents in writing, all
financial statements and reports furnished by the Company pursuant to Section
6(i) or otherwise furnished hereunder to the registered Holder hereof shall be
prepared and all computations and determinations pursuant hereto shall be made
in accordance with generally accepted accounting principles in the United States
consistently applied. This Warrant and any provision hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against whom enforcement of the same is sought. The headings in this
Warrant are for purposes of reference only and shall not affect the meaning or
construction of any provisions hereof.

                         [FORM OF CONSULTING AGREEMENT]



   45


                                     FORM OF
                              CONSULTING AGREEMENT

         This CONSULTING AGREEMENT (this "Agreement") is made as of
_______________, 1999 between Kevco, Inc, a Texas corporation (the "Company"),
and Mr. Gerald E. Kimmel (the "Consultant").

         WHEREAS, prior to the date hereof, the Consultant has served as the
Chairman of the Board of Directors of the Company (the "Board") and President
and Chief Executive Officer of the Company and has contributed greatly to the
Company's growth and success;

         WHEREAS, on the date hereof, in connection with certain business
transactions which the Company is completing and in consideration of the
Company's obligations hereunder, the Company and the Consultant have agreed to
terminate the Consultant's current Employment Agreement, dated as of October 1,
1996 (the "Existing Agreement"), and the Consultant is resigning from the
positions described above;

         WHEREAS, the Company desires to ensure the availability to the Company
of the Consultant's expertise and experience;

         WHEREAS, following the date hereof, the Consultant will continue to be
the beneficial owner of a substantial amount of the Company's outstanding voting
common stock;

         WHEREAS, the Company wishes the Consultant to continue to serve as a
Director of the Company and to serve as the non-executive Vice Chairman of the
Board and the Consultant is willing to and desirous of serving in such
positions; and

         WHEREAS, the Consultant is willing to provide such assistance and
assurance, all upon and subject to the terms and conditions contained in this
Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants set forth in this Agreement, the Company and the Consultant agree as
follows:

aspects of the Company's businesses with which the Consultant has particular
expertise or experience. In performing his duties hereunder, the Consultant
shall coordinate and communicate his efforts with the Board. The Consultant
shall not be required to follow any formal schedule of duties or assignments and
shall perform the consultancy in a manner that the Consultant determines is
reasonable. 



   46

2.       Compensation; Benefits.

         (a) Compensation. In consideration for the Consultant's consulting

and similar programs offered by the Company and its subsidiaries to their
respective employees generally (collectively the "Insurance Coverage"), and the
Company shall not take any action, or fail to take any action, the effect or
result of which would be to exclude or otherwise disqualify the Consultant or
Consultant's spouse from inclusion in the Insurance Coverage. During the Term,
the Company shall bear all costs and expenses of the Insurance Coverage for the
Consultant and the Consultant's spouse but at all times thereafter during the
Coverage Term, the Consultant shall bear the premium costs and shall be
responsible for all co-payments, deductibles, and all other costs in the same
manner and to the same extent as the active employees of the Company with
respect to such Insurance Coverage. During the Term, the Consultant or
Consultant's spouse cannot be included in or covered by the Insurance Coverage
or if there is no Insurance Coverage or to the extent there is no Insurance
Coverage, the Company shall obtain for Consultant or Consultant's spouse and
shall keep in full force and effect during the Term, comparable or additional
coverage for such persons; provided, however, if any such coverage is not
available or to the extent any of such coverage is not available, the Company
shall, at its sole cost and expense, pay or reimburse the Consultant and
Consultant's spouse for, all health, medical, dental, hospitalization,
deductibles, and other similar costs and expenses (collectively, the "Health
Costs") incurred or sustained by such persons during the Term not covered or
paid for by the Insurance Coverage or such other coverage, including the
insurance premiums for the Insurance Coverage or other coverage. In determining
whether coverage is "comparable coverage" the following factors, among others,
shall be considered relevant: quality of care, freedom to select facilities,
physicians, and other health care providers, relative financial responsibility
of insured and insurer to cover Health Costs, benefits and illnesses covered by
the applicable insurance, and each of obtaining health care provider services.

             If the Company desires to sell or otherwise transfer to a third
party all or substantially all of the assets or equity of the Company, the
Company covenants and agrees to and with the Consultant to cause such third
party to assume the obligations set forth in this paragraph 2(b), but any such
assumption shall not relieve the Company of its obligations hereunder. The
obligations of the Company under this paragraph 2(b) shall survive the
expiration of the Term.

         (c) Obligations Absolute. The Company's obligations in respect of the
compensation payments and medical and dental benefits provided herein shall be
an absolute obligation of the Company and shall be paid regardless of whether
the Consultant actually performs any consulting services during the Term and
such obligations shall not be subject to any claims or rights of set-off,
mitigation or otherwise.

less than twelve percent (12%) of the outstanding common stock of the Company,
the Company shall use its reasonable best efforts to ensure that at all times
the Consultant shall be a director of the Company and, to such end, the Company
agrees to (acting through the Board or otherwise) nominate the Consultant to
serve as a director of the Company, to include the Consultant in the slate of
nominees recommended by the Board to the Company's shareholders for election as

director of the Company, including by soliciting proxies in favor of the
election of the Consultant.

of the Company, the Company agrees to (acting through the Board or otherwise)

         (c) Reimbursement for Certain Expenses. The Company agrees that, in
addition to any rights the Consultant may have to indemnification or
reimbursement from the Company pursuant to the provisions of the Company's
charter, under applicable law or any applicable policy of insurance, in his
capacities as a present or former officer and/or director of the Company, the
Company will reimburse the Consultant for costs or expenses (including
reasonable attorney's fees and expenses) incurred in defending or responding to
any claim, action, suit, proceeding or investigation arising out of or
pertaining to this Agreement, the Stock Purchase Agreement, dated as of December
23, 1998, among the Consultant, the Company, and Wingate Partners II, L.P., the
Stock Purchase Agreement, dated as of December 23, 1998, between the Company and
Wingate Partners II, L.P. or any of the transactions contemplated hereby or
thereby, provided the Consultant is ultimately found not to be liable to the
Company or its shareholders in any such claim, action, suit, proceeding, or
investigation.
