                               PURCHASE AGREEMENT

     This Series C Preferred Stock Purchase Agreement (the "Agreement") dated as
of February 22, 1999 is entered into by and among Monitronics International,
Inc., a Texas corporation (the "Company"), and the Persons listed on Exhibit A
attached hereto (individually, a "Purchaser" and, collectively, the
"Purchasers"). Capitalized terms not defined elsewhere herein shall have the
respective meanings assigned to them in part 10 of this Agreement.

     In consideration of the mutual promises and covenants contained in this
Agreement, the parties agree as follows:

     1. Authorization and Sale of Shares.

          1A. Authorization. The Company has, or before the Closing (as defined
in part 2) will have, duly authorized the issuance and sale, pursuant to the
terms of this Agreement, of up to 1,409,375 shares of its Series C Preferred
Stock, having the rights, restrictions, privileges and preferences set forth in
the Articles of Amendment to the Articles of Incorporation attached as Exhibit B
(the "Articles of Amendment"). The Company has, or before the Closing will have,
adopted and filed the Articles of Amendment with the Secretary of State of the
State of Texas. The shares of Series C Preferred Stock being sold under this
Agreement and, unless the context otherwise requires, the shares of Class A
Common Stock issued or issuable upon the conversion of such shares of Series C
Preferred Stock are referred to as "Shares."

          1B. Sale of Shares of Series C Preferred Stock. Subject to the terms
and conditions of this Agreement, at the Closing, the Company will issue and
sell to the Purchasers, and each of the Purchasers will purchase, the number of
shares of Series C Preferred Stock set forth opposite such Purchaser's name on
Exhibit A for the purchase price of $ 19.689579 share. In the event CRL fails to
acquire the number of Shares set forth opposite its name on Exhibit A within
five (5) days following the Closing, Windward shall have the right to acquire
such Shares, pro rata based upon the number of Shares set forth opposite their
respective names on Exhibit A, on the same terms and conditions.

          1C. Separate Sales. The Company's agreement with each of the
Purchasers is a separate agreement, and the sale of Series C Preferred Stock to
each of the Purchasers is a separate sale.

          1D. Use of Proceeds. The Company will use the proceeds from the sale
of the Series C Preferred Stock as follows: (i) $20,181,819 for the acquisition
of substantially all of the assets of Dealers Monitoring Acquisition, L.P. (the
"DMAC Acquisition"); and (ii) $7,568,181 for the repurchase of certain
outstanding shares of Class A Common Stock, from those shareholders and in such
amounts and for such purchase price as set forth on Exhibit C attached hereto.

     2. The Closing. The closing of the issuance, sale and purchase of the
shares of Series C Preferred Stock under this Agreement (the "Closing") shall
take place on the date of the closing of the DMAC Acquisition but in no event
prior to March 4, 1999. The Closing shall be held at the offices of the Company,
12801 Stemmons Freeway, Suite 821, Dallas, Texas at 10:00

                                       1

<PAGE>

a.m., Central Time, on the date specified for such Closing above, or at such
other place or such other time as the Company and Windward may agree in writing.
At the Closing, the Company shall deliver to each of the Purchasers a
certificate representing the number of Shares of Series C Preferred Stock being
purchased by such Purchaser, registered in the name of such Purchaser, against
payment to the Company of the purchase price therefor, by wire transfer, check,
or other method acceptable to the Company. If at the Closing any of the
conditions specified in part S shall not have been fulfilled, each of the
Purchasers shall, at its election, be relieved of all of its obligations under
this Agreement to be performed at such Closing without thereby waiving any other
rights it may have by reason of such failure or such nonfulfillment.

     3. Representations and Warranties of the Company. Subject to and except as
disclosed by the Company in the Schedule of Exceptions attached as Exhibit D,
the Company hereby represents and warrants to each of the Purchasers as follows:

organized, validly existing and in good standing under the laws of the State of
Texas and has full corporate power and authority to conduct its business as
presently conducted and as proposed to be conducted by it and to enter into and
perform this Agreement and to carry out the transactions contemplated by this
Agreement. The Company is duly qualified and in good standing to do business as
a foreign corporation in each jurisdiction where the failure to be so qualified
would have a material adverse effect on the business, prospects, assets or
condition (financial or otherwise) of the Company. The Company has furnished to
each Purchaser true and complete copies of its Articles of Incorporation and
Bylaws, each as amended to date and currently in effect.

          3B. Capitalization. The authorized capital stock of the Company

                                       2

<PAGE>

otherwise) to purchase, redeem or otherwise acquire any shares of its capital
stock or any interest therein or to pay any dividend or make any other
distribution in respect thereof. All of the issued and outstanding shares of
capital stock of the Company have been offered, issued and sold by the Company
in compliance with applicable federal and state securities laws.

          3C. Subsidiaries, Etc. The Company has no Subsidiaries and does not
own or control, directly or indirectly, any shares of capital stock of any other
corporation or any interest in any partnership, joint venture or other
non-corporate business enterprise.

          3D. Shareholder List and Agreements. Exhibit D sets forth a true and
complete list of the shareholders of the Company, showing (both on a fully
diluted basis and non-fully diluted basis) the number and percentage of shares
of Class A Common Stock, Series A Preferred Stock, Series B Preferred Stock, the
Mezzanine Warrants, the Heller Warrant, the Preferred Warrants or other
securities of the Company (including options) held by each shareholder as of the
date of this Agreement and date of the Closing and the consideration paid to the
Company, if any, therefor. Except (i) pursuant to the 1994 Stock Plan, (ii) as
provided in this Agreement or any Ancillary Agreement, or (iii) as set forth in
Exhibit D, there are no agreements, written or oral, between the Company and any
holder of its capital stock, or, to the best of the Company's knowledge, among
any holders of its capital stock, relating to the acquisition (including without
limitation rights of first refusal or preemptive rights), disposition,
registration under the Securities Act, or voting of the capital stock of the
Company.

          3E. Issuance of Shares. The issuance, sale and delivery of the Series

delivery of the shares of Class A Common Stock issuable upon conversion of the
Series C Preferred Stock, have been, or will be on or prior to the Closing, duly
authorized by all necessary corporate action on the part of the Company, and all
such Shares have been duly reserved for issuance. The Series C Preferred Stock,
when so issued, sold and delivered against payment therefor in accordance with
the provisions of this Agreement, and Shares of Class A Common Stock issuable
upon conversion of the Series C Preferred Stock, when issued upon such
conversion in accordance with the Articles of Incorporation, will be duly and
validly issued, fully paid and non-assessable, free and clear of all Liens, and
not subject to any preemptive rights of any third party. Based in part on the
representations made by each of the Purchasers in part 4 of this Agreement, the
offer and sale of the Shares to each of the Purchasers will be in compliance
with applicable federal and state securities laws. Upon the closing of the
transactions contemplated by this Agreement, including the repurchase of Class A

aggregate 16.176% of the Common Stock calculated on a fully diluted basis.

          3F. Authority for Agreement. The execution, delivery and performance
by the Company of this Agreement and all Ancillary Agreements, and the
consummation by the Company of the transactions contemplated hereby and thereby,
have been duly authorized by all necessary corporate action. This Agreement and
the Ancillary Agreements have been duly executed and delivered by the Company
and constitute valid and binding obligations of the Company enforceable in
accordance with their respective terms. The execution, delivery and performance
of the transactions contemplated by this Agreement and the Ancillary Agreements
and compliance with their provisions by the Company will not violate any
provision of law and will not conflict with or result in any breach of any of
the terms, conditions or provisions of, or

                                       3

<PAGE>

constitute a default (with or without notice or lapse of time or both) under
which there would arise a right of termination, cancellation or acceleration of
any obligation or the loss of any right, or require a consent or waiver under,
the Articles of Incorporation or Bylaws (each as amended to date) or any
indenture, lease, agreement or other loan document provision or instrument to
which the Company is a party or by which it or any of its properties is bound,
or any decret, judgment, order, statute, law, ordinance, rule or regulation
applicable to the Company or its assets or properties.

          3G. Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any Governmental Authority is required on the part of the Company
in connection with the execution and delivery of this Agreement, the offer,
issuance, sale and delivery of the Shares, or the other transactions to be
consummated at the Closing, as contemplated by this Agreement, except for
filings, if any, required under the HSR Act and such filings as shall have been
made prior to and shall be effective on and as of each Closing.

          3H. Litigation. There is no action, suit or administrative proceeding,
or governmental inquiry or investigation, pending, or, to the best of the
Company's knowledge, any basis therefor or threat thereof, against the Company,
which questions the validity of this Agreement or any Ancillary Agreement or the
right of the Company to enter into or perform this Agreement or any Ancillary
Agreement, or which could reasonably be expected to have, either individually or
in the aggregate, any material adverse effect on the business, prospects, assets
or condition, financial or otherwise, of the Company, nor is there any
litigation pending, or, to the best of the Company's knowledge, any basis
therefor or threat thereof, against the Company by reason of the proposed
activities of the Company or negotiations by the Company with possible investors
in the Company, nor is there any judgment, decree, injunction, rule or order of
any court, Governmental Authority, instrumentality or arbitrator outstanding
against the Company having or likely to have the effect of preventing the
consummation of the transaction contemplated by this Agreement or having or
likely to have a material adverse effect on the business, prospects, assets or
condition (financial or otherwise) of the Company.

          3I. Financial Statements. The Company has furnished to each of the
Purchasers a complete and correct copy of the following financial statements
(collectively, the "Financial Statements"): (i) the Company's audited balance
sheet, statement of income, changes in shareholders' equity, and cash flows for
the fiscal year end June 30, 1998, and (ii) the Company's unaudited balance
sheet (the "Balance Sheet") as of December 31, 1998 (the "Balance Sheet Date")
and the related statement of operations and cash flow for the six-month period
ended as of the Balance Sheet Date (the "Most Recent Financial Statements"). The
Financial Statements are complete and correct, are in accordance with the books
and records of the Company and present fairly the financial condition and
results of operations of the Company, as at the dates and for the periods
indicated, and have been prepared in accordance with generally accepted
accounting principles consistently applied, except that the Most Recent
Financial Statements lack footnotes and other presentation items and are subject
to normal year-end audit adjustments, which will not be material, individually
or in the aggregate.

          3J. Absence of Liabilities. Except as disclosed in Exhibit D, at the
Balance Sheet Date, the Company did not have any indebtedness, obligations or
liabilities of any type,

                                       4

<PAGE>

and there is no basis for any claim or liability of any nature against the
Company, that in the aggregate exceeded $100,000, whether accrued, absolute,
contingent or otherwise, and whether due or to become due or asserted or
unasserted, which were not fully reflected on the Balance Sheet, and since the
Balance Sheet Date the Company has not incurred or otherwise become subject to
any of the foregoing except in the ordinary course of business consistent with
past practice.

          3K. Taxes. The amount shown on the Balance Sheet as provision for
taxes is sufficient in all material respects for payment of all accrued and
unpaid federal, state, county, local and foreign taxes for the period then ended
and all prior periods. The Company has filed all federal, state, county, local
and foreign tax returns which are required to be filed by it on or prior to the
date of each Closing, except where such failure to file would not have a
material adverse effect on the business, prospects, assets or condition
(financial or otherwise) of the Company, such returns are true and correct and
all taxes shown thereon to be due have been timely paid with exceptions not
material to the Company. Federal income tax returns of the Company have not been
audited by the Internal Revenue Service, and no controversy with respect to
taxes of any type is pending or, to the best of the Company's knowledge,
threatened. Neither the Company nor any of its shareholders has ever filed (i)
an election pursuant to Section 1362 of the Code, that the Company be taxed as
an S Corporation or (ii) a consent pursuant to Section 341(f) of the Code
relating to collapsible corporations.

          3L. Property and Assets. The Company has good and indefeasible title
to or a valid leasehold interest in all of its properties and assets, which
comprise all of the properties and assets reflected in the Balance Sheet (except
those disposed of since the Balance Sheet Date in the ordinary course of
business) and all of the properties and assets necessary or useful for the
conduct of its business and none of such properties or assets is subject to any
Lien of any nature whatsoever other than those the material terms of which are
described in the Balance Sheet or in Exhibit D.

          3M. Intellectual Property. The Company is the sole owner of or
possesses all legal rights to all patents, patent applications, trademarks,
service marks, trademark and service mark applications, trade names, copyrights,
trade secrets, licenses, information and proprietary rights and processes
presently used by the Company or necessary for the conduct of the Company's
business as conducted and as proposed to be conducted (the "Intellectual
Property Rights"). The Company has taken all actions reasonable in light of its
financial position to protect the Intellectual Property Rights and, no Person is
infringing or violating any of such rights. The business conducted or proposed
to be conducted by the Company does not and will not cause the Company to
infringe or violate any of the trademarks, service marks, trade names,
copyrights, licenses, trade secrets or other intellectual property rights or the
patents of any other Person, and, except as set forth in Exhibit D, does not and
will not require the Company to obtain any license or other agreement to use any
trademarks, service marks, trade names, copyrights, licenses, trade secrets or
other intellectual property rights or patents of others. Except for standard
end-user license agreements, there are no outstanding options, licenses or
agreements of any kind relating to the Intellectual Property Rights, nor is the
Company bound by or a party to any options, licenses or agreements of any kind
with respect to the patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses, information and proprietary rights and processes of any
other Person. The Company has not received any communications alleging that

                                       5

<PAGE>

the Company has violated or, by conducting its business as proposed to be
conducted, would violate any of the patents, trademarks, service marks, trade
names, copyrights, trade secrets, licenses, information and proprietary rights
and processes of any other Person. Exhibit D contains a complete list of
patents, pending patent applications, trademarks and service marks of the
Company. The Company is not aware that any employee of the Company is obligated
under any contract (including any license, covenant or commitment of any
nature), or subject to any judgment, decree or order of any court or
administrative agency, that would conflict or interfere with (i) the performance
of the any employee's duties as an officer, employee or director of the Company,
(ii) the use of any employee's best efforts to promote the interests of the
Company, or (iii) the Company's business as conducted or proposed to be
conducted. The Company does not believe that it is or will be necessary to use
any inventions or works of authorship of its employees (or persons it currently
intends to hire) made prior to their employment by the Company.

          3N. Insurance. The Company maintains valid policies of insurance with
respect to its properties and business of the kinds and in the amounts not less
than is customarily obtained by corporations engaged in the same or similar
business and similarly situated, including, without limitation, workers
compensation insurance and insurance against casualty loss, public liability,
libel, slander, defamation, advertising injury and other risks. Exhibit D sets
forth a schedule and brief description of the policies of insurance currently
maintained by the Company. With respect to each such insurance policy: (i) the
policy is in full force and effect; (ii) the Company is not in breach or default
(including with respect to the payment of premiums or the giving of notices),
and no event has occurred which, with notice or the lapse of time, would
constitute such a breach or default or permit termination, cancellation,
modification or denial of coverage under the policy and (iii) no party to the
policy has repudiated any of its provisions.

          3O. Material Contracts and Obligations. Exhibit D sets forth a list of
all material agreements or commitments of any nature to which the Company is a
party or by which it is bound (other than existing agreements to purchase
monitoring alarm contracts), including without limitation (i) each agreement
which requires future expenditures by the Company in excess of $100,000 or which
might result in payments to the Company in excess of $100,000, (ii) all
employment and consulting agreements, employee benefit, bonus, pension,
profit-sharing, stock option, stock purchase and similar plans and arrangements,

regulations promulgated under the Securities Act), including without limitation
any agreement or other arrangement providing for the furnishing of services by,
rental of real or personal property from, or otherwise requiring payments to,

foresees in the future is reasonably likely to materially adversely affect, the
business, prospects, assets or condition, financial or otherwise, of the
Company. To the best of the Company's knowledge, no employee of the Company is

payment of dividends under this paragraph 1H, dividends shall continue to accrue

     2A. In the event of any liquidation, dissolution or winding up of the
corporation, either voluntary or involuntary:

          (i) The holders of the Series C Preferred Stock shall be entitled to
     receive, prior and in preference to any distribution of any of the assets
     or surplus funds of the corporation to the holders of the Series A
     Preferred Stock, Series B Preferred Stock or Common Stock by reason of
     their ownership thereof, an amount for each share of Series C Preferred
     Stock then held by them equal to $ 19.689579 (as adjusted for any stock
     dividends, combinations or splits with respect to such shares) plus accrued
     or declared but unpaid dividends on the Series C Preferred Stock (the
     "Series C Liquidation Value"). If upon the occurrence of such event, the
     assets and funds thus distributed among the holders of the Series C
     Preferred Stock shall be insufficient to permit the payment to such holders
     of such full preferential amount, then the entire assets and funds of the
     corporation legally available for distribution shall be distributed ratably
     among the holders of the Series C Preferred Stock in proportion to the
     shares of Series C Preferred Stock then held by them.

          (ii) After payment to the holders of the Series C Preferred Stock of
     the full amount to which they are entitled under subparagraph (i) above,
     the holders of the Series B Preferred Stock shall be entitled to receive,
     prior and in preference to any distribution of any of the assets or surplus
     funds of the corporation to the holders of the Series A Preferred Stock by
     reason of their ownership thereof, an amount for each share of Series B
     Preferred Stock then held by them equal to $1.00 (as adjusted for any stock
     dividends, combinations or splits with respect to such shares) plus accrued
     or declared but unpaid dividends on the Series B Preferred Stock (the
     "Series B Liquidation Value"). If upon the occurrence of such event, the
     assets and funds thus distributed among the holders of the Series B
     Preferred Stock shall be insufficient to permit the payment to such holders
     of such full preferential amount, then the entire assets and funds of the
     corporation legally available for distribution shall be distributed ratably
     among the holders of the Series B Preferred Stock in proportion to the
     shares of Series B Preferred Stock then held by them.

          (iii) After payment to the holders of the Series C Preferred Stock and
     Series B Preferred Stock of the full amount to which they are entitled
     under subparagraphs (i) and (ii) above, the holders of the Series A
     Preferred Stock shall be entitled to receive, prior and in preference to
     any distribution of any of the assets or surplus funds of the corporation
     to the holders of the Common Stock by reason of their ownership thereof, an
     amount for each share of Series A Preferred Stock then held by them equal
     to $1.00 (as adjusted for any stock dividends, combinations or splits with
     respect to such shares) plus accrued or declared but unpaid dividends on
     the Series A Preferred Stock (the "Series A Liquidation Value"). If upon
     the occurrence of such event, the assets and funds thus distributed among
     the holders of the Series A Preferred Stock shall be insufficient

<PAGE>

     to permit the payment to such holders of such full preferential amount,
     then the entire assets and funds of the corporation legally available for
     distribution shall be distributed ratably among the holders of the Series A
     Preferred Stock in proportion to the shares of Series A Preferred Stock
     then held by them.

          (iv) Subject to the payment in full of the Series C Liquidation
     Preference, the Series B Liquidation Preference and the Series A
     Liquidation Preference as provided in subparagraphs (i), (ii) and (iii)
     above, all remaining assets and surplus funds of the corporation shall be
     distributed among holders of Common Stock and the holders of Series A
     Preferred Stock, ratably in proportion to the shares of Common Stock then
     held by them and the shares of Common Stock into which the shares of Series
     A Preferred Stock then held by them could be converted.

     2B. For purposes of this part 2, a "liquidation" shall, at the option of
the holders of at least 66-2/3% of the outstanding shares of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock, voting together as
a single class and not as a separate series, include:

          (i) a consolidation or merger of the corporation with or into any
     other corporation, or any other Person, other than a wholly-owned

     shareholders of the corporation prior to the transaction will maintain
     voting control of the resulting entity after the transaction;

          (ii) any corporate reorganization in which the corporation shall not
     be the continuing or surviving entity resulting from such reorganization;

          (iii) a sale of all or substantially all of the assets of the
     corporation; or

          (iv) a share exchange in which any Person acquires all of the
     outstanding shares of any class or series of capital;

such that the holders of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock shall be paid in cash or in securities received from
the acquiring corporation, or in a combination thereof, at the closing of any
such transaction, an amount equal to the amount per share which would be payable
to the holders of Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock pursuant to this part 2 in a liquidation of the corporation.

     2C. Any securities to be delivered to the holders of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock pursuant to
paragraph 2B above shall be valued as follows:

          (i) Securities not subject to restrictions on free transferability:

               (a) if traded on a securities exchange, the value shall be deemed
          to be the average of the security's closing prices on such

<PAGE>

          exchange over the 30-day period ending three days prior to the
          closing;

               (b) if actively traded over-the-counter, the value shall be
          deemed to be the average of the closing bid prices over the 30-day
          period ending three days prior to the closing; and

               (c) if there is no active public market, the value shall be the
          fair market value thereof, as mutually determined by a majority of the
          disinterested directors and the holders of a majority of the
          outstanding shares of Series A Preferred Stock, Series B Preferred
          Stock and Series C Preferred Stock, voting together as a separate
          class or series, or, in the absence of such agreement, by an
          independent appraisal paid for by the corporation; and

          (ii) Securities subject to investment letter or other restrictions on
     free marketability shall be valued at an appropriate discount from the
     market value determined as above in subparagraphs (i)(a), (i)(b) or (i)(c)
     to reflect the approximate fair market value thereof, as mutually
     determined by a majority of the disinterested directors and the holders of
     a majority of the outstanding Series A Preferred Stock, Series B Preferred
     Stock and Series C Preferred Stock, voting together as a separate class or
     series or, in the absence of such agreement, by an independent appraisal
     paid for by the corporation.

     2D. The corporation shall give each holder of record of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock written notice of
such impending transaction not later than 20 days prior to the shareholders
meeting called to approve such transaction or 20 days prior to the closing of
such transaction, whichever is earlier, and shall also notify such holders in
writing of the final approval of such transaction. The first of said notices
shall describe the material terms and conditions of the contemplated transaction
as well as the terms and conditions of this part 2, and the corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than 20 days after the mailing
by the corporation of the first notice provided for herein or sooner than 20
days after the mailing by the corporation of any notice of material changes
provided for herein; provided, however, that such periods may be shortened upon
the written consent of the holders of a majority of the outstanding Series A

share of Series C Preferred Stock to be redeemed on such Mandatory Redemption
Date equal to $ 19.689579 (as adjusted for stock dividends, combinations or
splits with respect to such shares), plus any accrued or declared but unpaid
dividends on the Series C Preferred Stock (the "Series C Redemption Price").

     3G. If the funds of the corporation legally available for redemption of
Series C Preferred Stock on the Mandatory Redemption Date are insufficient to
redeem the total number

<PAGE>

of shares of Series C Preferred Stock to be redeemed on the Mandatory Redemption
Date, those funds that are legally available will be applied to the Series C
Preferred Stock, ratably among the holders of the shares to be redeemed based
upon the aggregate Series C Redemption Price of such shares held by each such
holder. At any time and from time to time thereafter when additional funds of
the corporation are legally available for redemption of shares of Series C
Preferred Stock, such funds immediately will be applied to redeem the balance of
the shares of Series C Preferred Stock that have not been redeemed and such
funds will not be used for any other purpose, including to redeem any shares of
Series B Preferred Stock or Series A Preferred Stock that the corporation is
obligated to redeem. If the funds of the corporation legally available for
redemption of all classes or series of Preferred Stock to be redeemed on the
Mandatory Redemption Date are insufficient to redeem the total number of shares
of Preferred Stock to be redeemed on the Mandatory Redemption Date, those funds
that are legally available will be applied first to the Series C Preferred
Stock, ratably among the holders of the shares to be redeemed based upon the
aggregate Series C Redemption Price of such shares held by each such holder, and
thereafter those funds legally available will be applied to the Series B
Preferred Stock, and thereafter those funds legally available will be applied to
the Series A Preferred Stock.

     3H. If the funds of the corporation legally available for redemption of
Series B Preferred Stock on the Series B Redemption Date are insufficient to
redeem the total number of shares of Series B Preferred Stock to be redeemed on
the Series B Redemption Date, those funds that are legally available will be
applied to the Series B Preferred Stock, ratably among the holders o~ the shares
to be redeemed based upon the aggregate Series B Redemption Price of such shares
held by each such holder. At any time and from time to time thereafter when
additional funds of the corporation are legally available for redemption of
shares of Series B Preferred Stock, such funds immediately will be applied to
redeem the balance of the shares of Series B Preferred Stock that have not been
redeemed and such funds will not be used for any other purpose, including to
redeem any shares of Series A Preferred Stock that the corporation is obligated
to redeem.

     3I. If the funds of the corporation legally available for redemption of
Series A Preferred Stock on the Mandatory Redemption Date are insufficient to
redeem the total number of shares of Series A Preferred Stock to be redeemed on
the Mandatory Redemption Date, those funds that are legally available will be
applied to the Series A Preferred Stock ratably among the holders of the shares
to be redeemed based upon the aggregate Series A Redemption Price of such shares
held by each such holder. At any time and from time to time thereafter when
additional funds of the corporation are legally available for redemption of
shares of Series A Preferred Stock, such funds immediately will be applied to
redeem the balance of the shares of Series A Preferred Stock that the
corporation has become obligated to redeem on the Mandatory Redemption Date but
which it has not redeemed and such funds will not be used for any other purpose.

     3J. No share of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock is entitled to any dividends accruing after the date on
which the Series A Redemption Price, the Series B Redemption Price or the Series
C Redemption Price, respectively, is paid. On such date, all rights of the
holder of such share of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock will cease, and such share of Series

<PAGE>

A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock will not
be deemed to be outstanding.

     3K. Any shares of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock that are redeemed or otherwise acquired by the
corporation will be cancelled and will not be reissued, sold or transferred. If
fewer than the total number of shares of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock represented by any certificate are
redeemed, a new certificate representing the number of unredeemed shares of
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock
will be issued to the holder thereof without cost to such holder within three
business days after surrender of the certificate representing the redeemed
shares.

     3L. Neither the corporation nor any Subsidiary will redeem, repurchase or
otherwise acquire any shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, except as expressly authorized herein or
pursuant to a purchase offer made (i) pro-rata to all holders of shares of
Series C Preferred Stock on the basis of the number of shares of Series C
Preferred Stock owned by each such holder, (ii) pro-rata to all holders of
shares of S~..1ies B Preferred Stock on the basis of the number of shares of
Series B Preferred Stock owned by each such holder and only if all shares of
Series C Preferred Stock have been redeemed, repurchased or otherwise acquired
by the corporation or (iii) pro-rata to all holders of shares of Series A
Preferred Stock on the basis of the number of shares of Series A Preferred Stock
owned by each such holder and only if all shares of Series C Preferred Stock and
Series B Preferred Stock have been redeemed, repurchased or otherwise acquired
by the corporation.

     3M. Notwithstanding anything in this part 3 to the contrary, neither the
corporation nor any Subsidiary will redeem, repurchase or otherwise acquire any
shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock while any Notes are outstanding, or if prohibited under the
Credit Agreement. If on the date that the holders of the Series A Preferred
Stock and the Series C Preferred Stock could elect to require the corporation to
effect the Series A Mandatory Redemption and the Series C Mandatory Redemption
any Notes are outstanding or the redemption of the Series A Preferred Stock,
Series B Preferred Stock and the Series C Preferred Stock is prohibited under
the Credit Agreement, the time for giving such notice shall be extended until
100 days following the date (the "Extension Date") upon which no Notes remain
outstanding and the redemption of the Series A Preferred Stock, the Series B
Preferred Stock and the Series C Preferred Stock is no longer prohibited under
the Credit Agreement. If the holders of a majority of the outstanding shares of
Series A Preferred Stock give written notice to the corporation within the
100-day period following the Extension Date of their election to require the
Series A Mandatory Redemption, the corporation (and such holders) shall be
obligated to redeem the Series A Preferred Stock pursuant to paragraph 3B on the
date 120 days following the Extension Date (the "Extended Mandatory Redemption
Date") and the Extended Mandatory Redemption Date shall be deemed the Mandatory
Redemption Date for purposes of paragraph 3B. If the holders of a majority of
the outstanding shares of Series C Preferred Stock give written notice to the
corporation within the 100-day period following the Extension Date of their
election to require the Series C Mandatory Redemption, the corporation (and such
holders) shall be obligated to redeem the Series C Preferred Stock pursuant to
paragraph 3C on the Extended Mandatory Redemption Date and the Extended
Mandatory Redemption Date shall be deemed the Mandatory Redemption Date for
purposes of paragraph

<PAGE>

3C. If on the Series B Redemption Date any Notes are outstanding or the
redemption of the Series B Preferred Stock is prohibited under the Credit
Agreement, the corporation (and the holders of the Series B Preferred Stock)
shall be obligated to redeem the Class B Preferred Stock pursuant to paragraph
3A on the date 120 days following the Extension Date (the "Extended Series B
Redemption Date") and the Extended Series B Redemption Date shall be deemed the
Series B Redemption Date for purposes of paragraph 3A.

     Part 4. Voting Rights.

     4A Except as otherwise provided in these Articles of Incorporation or the
Act, the Series A Preferred Stock and, upon the expiration of any waiting period

corporation, and the Common Stock shall not be entitled to vote as a class on
any matter. Except as otherwise provided in these Articles of Incorporation or
the Act, the holders of Series B Preferred Stock will have no right to vote
their shares of Series B Preferred Stock on any matters to be voted on by the
shareholders of the corporation. Except as otherwise provided in these Articles
of Incorporation or the Act, the holders of Class A Common Stock will be
entitled to one vote per share on all matters voted on by the shareholders of
the corporation and the holders of Class B Common Stock will have no right to
vote their shares of Class B Common Stock on any matters to be voted on by the
shareholders of the corporation.

     4B. Without first obtaining the approval or consent of the holders of at
least 66-2/3% of the outstanding shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock, voting together as a separate
class or series, the corporation shall not:

          (i) issue any capital stock, options, warrants or rights to purchase
     or acquire capital stock, or any other equity securities, other than (A)
     pursuant to an Approved Plan, (B) upon conversion of shares of Series A
     Preferred Stock, (C) upon conversion of shares of Series B Preferred Stock,
     (D) upon conversion of shares of Series C Preferred Stock, (E) the issuance
     of the Warrant Shares upon the exercise of the Warrants or (F) the Class A
     Common Stock issuable upon conversion of any outstanding Class B Common
     Stock;

          (ii) sell or dispose of in any manner all or any substantial portion
     of its properties or assets, liquidate, dissolve or enter into any merger,
     consolidation or similar transaction; or

     assets, purchase of stock or other securities, merger or otherwise, or
     create any Subsidiary other than a wholly owned Subsidiary), other than
     purchases (either directly, or indirectly through the purchase of 100% of
     the outstanding stock of the Person) of monitoring alarm contracts in the
     ordinary course of business of the corporation or pursuant to the DMAC
     Acquisition (as defined in the Series C Purchase Agreement).

<PAGE>

     4C. Without first obtaining the approval or consent of the holders of at
least 66-2/3% of the outstanding shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock, each voting as a single and
separate class or series, the corporation shall not:

          (i) amend the Articles of Incorporation or bylaws of the corporation;
     or

          (ii) purchase, redeem or otherwise acquire or retire for value any of
     its capital stock or other equity securities or declare or make any
     dividend or other distribution with respect to any of its capital stock or
     other equity securities (other than a dividend or distribution payable
     solely in shares of Common Stock), except that this provision shall not
     prevent the repurchase by the corporation of capital stock from employees
     at cost pursuant to agreements with such employees approved by the Board of
     Directors (with a majority of the Purchaser Directors concurring).

     Part 5. Conversion

     The holders of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock shall have conversion rights as follows (the
"Conversion Rights"):

     5A. Right to Convert.

     Subject to the provisions of paragraph 5C, (i) each share of Series A
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, at the office of the
corporation or any transfer agent for such share, into such number of fully paid
and nonassessable shares of Class A Common Stock as is determined by dividing
$1.00 by the Series A Conversion Price (as defined below) in effect at the time
of conversion, (ii) each share of Series B Preferred Stock shall be convertible,
at the option of the holder thereof, simultaneously upon the closing of a
Qualified Public Offering, into such number of fully paid and nonassessable
shares of Class A Common Stock as is determined by dividing the Series B
Redemption Price at the time of closing of such Qualified Public Offering by the
Public Offering Price (as defined in paragraph 5C) in such Qualified Public
Offering, and (iii) each share of Series C Preferred Stock shall be convertible,
at the option of the holder thereof, at any time after the date of issuance of
such share, at the office of the corporation or any transfer agent for such
share, into such number of fully paid and nonassessable shares of Class A Common
Stock as is determined by dividing $ 19.689579 by the Series C Conversion Price
(as defined below) in effect at the time of conversion.

     5B. Automatic Conversion. Each share of Series A Preferred Stock shall
automatically be converted into shares of Class A Common Stock at the then
effective Series A Conversion Price immediately upon the closing of a Qualified
Public Offering. Each share of Series C Preferred Stock shall automatically be
converted into shares of Class A Common Stock at the then effective Series C
Conversion Price immediately upon the closing of a Qualified Public Offering.

     5C. Mechanics of Conversion. Before any holder of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall be entitled to
convert shares of Series A

<PAGE>

Preferred Stock, Series B Preferred Stock or Series C Preferred Stock into
shares of Class A Common Stock, such holder shall surrender the certificate or
certificates thereof, duly endorsed, at the office of the corporation or of any
transfer agent for such shares, and shall give written notice to the corporation
at such office that he elects to convert the same and shall state therein the
name or names in which the certificate or certificates for shares of Class A
Common Stock are to be issued. The corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock a
certificate or certificates for the number of shares of Class A Common Stock to
which the holder shall be entitled as aforesaid. Such conversion shall be deemed
to have been made immediately prior to the close of business on the date of
surrender of the shares of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock to be converted, and the Person or Persons entitled to
receive the shares of Class A Common Stock issuable upon such conversion shall
be treated for all purposes as the record holder or holders of such shares of
Class A Common Stock on such date. hi the event of an automatic conversion of
the Series A Preferred Stock or Series C Preferred Stock, the Board of Directors
may elect to treat the conversion of the shares of Series A Preferred Stock or
Series C Preferred Stock as having been made effective as of the date of the
event resulting in the automatic conversion.

     5D. Adjustments to Conversion Prices for Dilutive Issues.

          (i) Conversion Prices. The initial Series A Conversion Price shall be
     $1.00 per share. The initial Series C Conversion Price shall be $19.689579
     per share. The Series A Conversion Price and the Series C Conversion Price
     shall be subject to adjustment as set forth in this paragraph 5D.

          (ii) Special Definitions. For purposes of this paragraph 5D, the
     following definitions apply:

               (a) "Options" shall mean rights, options, or warrants to

          securities convertible into or exchangeable for Common Stock.

               (c) "Additional Shares of Common Stock" shall mean all shares of
          Common Stock issued (or, pursuant to 5D(iv), deemed to be issued) by
          the corporation after the Series C Original Issue Date other than
          shares of Common Stock issued or issuable:

                    (1) upon conversion of shares of the Series A Preferred
               Stock, Series B Preferred Stock or Series C Preferred Stock;

                    (2) to officers, directors or employees of, or consultants

               options granted pursuant to any Approved Plan);

                    (3) as a dividend or distribution on Series A Preferred
               Stock, Series B Preferred Stock or Series C Preferred Stock;

                    (4) pursuant to a transaction for which adjustment of the
               Series A Conversion Price or the Series C Conversion price, as
               the case may be, is made pursuant to paragraph 5D(v) or 5D(vi),
               respectively;

                    (5) pursuant to the acquisition of another Person by merger,

               (exclusive of the DMAC Acquisition) or reorganization; or

                    (6) upon the exercise of the Warrants or the conversion of
               Class B Common Stock into Class A Common Stock.

          (iii) No Adjustment of Conversion Price. No adjustment in the Series A
     Conversion Price of a particular share of Series A Preferred Stock shall be
     made in respect of the issuance of Additional Shares of Common Stock unless
     the consideration per share for an Additional Share of Common Stock issued
     or deemed to be issued by the corporation is less than the Series A
     Conversion Price in effect on the date of, and immediately prior to such
     issue, for such share of Series A Preferred Stock. No adjustment in the
     Series B Conversion Price of a particular share of Series B Preferred Stock
     shall be made in respect of the issuance of Additional Shares of Common
     Stock. No adjustment in the Series C Conversion Price of a particular share
     of Series C Preferred Stock shall be made in respect of the issuance of
     Additional Shares of Common Stock unless the consideration per share for an
     Additional Share of Common Stock issued or deemed to be issued by the
     corporation is less than the Series C Conversion Price in effect on the
     date of, and immediately prior to such issue, for such share of Series C
     Preferred Stock.

          (iv) Deemed Issue of Additional Shares of Common Stock. In the event
     the corporation at any time or from time to time after the Series C
     Original Issue Date shall issue any Options or Convertible Securities or
     shall fix a record date for the determination of holders of any class of
     securities then entitled to receive any such Options or Convertible
     Securities, then the maximum number of shares (as set forth in the
     instrument relating thereto without regard to any provisions contained
     therein designed to protect against dilution) of Common Stock issuable upon
     the exercise of such Options or, in the case of Convertible Securities and
     Options therefor, the conversion or exchange of such Convertible
     Securities, shall be deemed to be Additional Shares of Common Stock issued
     as of the time of such issue or, in case such a record date shall have been
     fixed, as of the close of business on such record date, provided that
     Additional Shares of Common Stock shall not be deemed to have been issued
     unless the consideration per share (determined pursuant to paragraph
     5D(vii) hereof) of such Additional

<PAGE>

     Shares of Common Stock would be less than the Series A Conversion Price or
     Series C Conversion Price, as the case may be, in effect on the date of and
     immediately prior to such issue, or such record date, as the case may be,
     and provided further that in any such case in which Additional Shares of
     Common Stock are deemed to be issued:

               (a) no further adjustments in the Series A Conversion Price or
          Series C Conversion Price shall be made upon the subsequent issue of
          Convertible Securities or shares of Common Stock upon the exercise of
          such Options or conversion or exchange of such Convertible Securities;

               (b) if such Options or Convertible Securities by their terms
          provide, with the passage of time or otherwise, for any increase in
          the consideration payable to the corporation, or decrease in the
          number of shares of Common Stock issuable upon the exercise,
          conversion or exchange thereof, then the Series. A Conversion Price or
          Series C Conversion Price computed upon the original issue thereof (or
          upon the occurrence of a record date with respect thereto), and any
          subsequent adjustments based thereon, shall, upon any such increase or
          decrease becoming effective, be recomputed to reflect such increase or
          decrease insofar as it affects such Options or the rights of
          conversion or exchange under such Convertible Securities (provided,
          however, that no such adjustment of the Series A Conversion Price or
          the Series C Conversion Price shall affect Common Stock previously
          issued upon conversion of Series A Preferred Stock or Series C
          Preferred Stock).

               (c) upon the expiration of any such Options or any rights of
          conversion or exchange under such Convertible Securities which shall
          not have been exercised, the Series A Conversion Price or Series C
          Conversion Price computed upon the original issue thereof (or upon the
          occurrence of a record date with respect thereto), and any subsequent
          adjustments based thereon, shall, upon such expiration, be recomputed
          as if:

                    (1) in the case of Convertible Securities or Options for
               Common Stock the only Additional Shares of Common Stock issued
               were the shares of Common Stock, if any, actually issued upon the
               exercise of such Options or the conversion or exchange of such
               Convertible Securities and the consideration received therefor
               was the consideration actually received by the corporation for
               the issue of all such Options, whether or not exercised, plus the
               consideration actually received by the corporation upon such
               exercise, or for the issue of all such Convertible Securities
               which were actually converted or exchanged, plus the additional
               consideration, if any, actually received by the corporation upon
               such conversion or exchange, and

<PAGE>

                    (2) in the case of Options for Convertible Securities, only
               the Convertible Securities, if any, actually issued upon the
               exercise thereof were issued at the time of issue of such Options
               and the consideration received by the corporation for the
               Additional Shares of Common Stock deemed to have been then issued
               was the consideration actually received by the corporation for
               the issue of all such Options, whether or not exercised, plus the
               consideration deemed to have been received by the corporation
               (determined pursuant to paragraph 5D(vii)) upon the issue of the
               Convertible Securities with respect to which such Options were
               actually exercised;

               (d) no adjustment of the conversion rate for the Series A
          Preferred or Series C Preferred Stock shall have the effect of
          increasing the Series A Conversion Price or Series C Conversion Price
          to an amount which exceeds the lower of (1) the Series A Conversion
          Price or Series C Conversion Price on the original adjustment date, or
          (2) the Series A Conversion Price or Series C Conversion Price that
          would have resulted from any actual issuance of Additional Shares of
          Common Stock between the original adjustment date and such
          readjustment date;

               (e) in the case of any Options that expire by their terms not
          more than 30 days after the date of issue thereof, no adjustment of
          the Series A Conversion Price or the `Series C Conversion price shall
          be made, except as to shares of Series A Preferred Stock or Series C
          Preferred Stock converted during such period, until the expiration or
          exercise of all such Options, whereupon such adjustment shall be made
          in the same manner provided in clause (c) above; and

               (f) if any such record date shall have been fixed and such
          Options or Convertible Securities are not issued on the date fixed
          thereof, the adjustment previously made in the Series A Conversion
          Price or Series C Conversion Price that became effective on such
          record date shall be cancelled as of the close of business on such
          record date, and shall instead be made on the actual date of issuance,
          if any.

          (v) Adjustment of Series A Conversion Price Upon Issuance of
     Additional Shares of Common Stock. In the event the corporation, at any
     time after the Series C Original Issue Date, shall issue Additional Shares
     of Common Stock (including Additional Shares of Common Stock deemed to be
     issued pursuant to paragraph 5D(iv)) without consideration or for a
     consideration per share less than the Series A Conversion Price in effect
     on the date of and immediately prior to such issue, then and in such event,
     such Series A Conversion Price shall be reduced, concurrently with such
     issue, to the price (calculated to the nearest $00001) obtained by
     multiplying the Series A Conversion Price in effect

<PAGE>

     immediately prior to the time of such issue or sale by a fraction, the
     numerator of which shall be (i) the number of shares of Common Stock
     outstanding (or deemed to be outstanding hereunder) immediately prior to
     such issue or sale multiplied by the Series A Conversion Price immediately
     prior to such issue or sale plus (ii) the consideration received (or deemed
     to be received hereunder) by the corporation upon such issue or sale, and
     the denominator of which shall be the product of (iii) the total number of
     shares of Common Stock outstanding (or deemed to be outstanding hereunder)
     immediately after such issue or sale, multiplied by (iv) the Series A
     Conversion Price immediately prior to such issue or sale. Notwithstanding
     the foregoing, no adjustment of the Series A Conversion Price shall be made
     in an amount less than 50.0001 per share, but any such lesser adjustment
     shall be carried forward and shall be made at the time of and together with
     the next subsequent adjustment which together with any adjustments so
     carried forward shall amount to 50.0001 per share' or more. Upon each
     adjustment of the Series A Conversion Price, the Series A Preferred Stock
     shall thereafter be convertible, at the Series A Conversion Price resulting
     from such adjustment, into the number of shares of Class A Common Stock
     obtained by multiplying the Series A Conversion Price in effect immediately
     prior to such adjustment by the number of shares of Class A Common Stock
     into which the Series A Preferred Stock was convertible pursuant hereto
     immediately prior to such adjustment and dividing the product thereof by
     the Series A Conversion Price resulting from such adjustment.

          (vi) Adjustment of Series C Conversion Price Upon Issuance of
     Additional Shares of Common Stock. In the event the corporation, at any
     time on or prior to the first anniversary of the Series C Original Issue
     Date shall issue Additional Shares of Common Stock (including Additional
     Shares of Common Stock deemed to be issued pursuant to paragraph 5D(iv))
     without consideration or for a consideration per share less than the Series
     C Conversion Price in effect on the date of and immediately prior to such
     issue, then and in such event, such Series C Conversion Price shall be
     reduced, concurrently with such issue, to a price equal to the
     consideration per share, if any, received by the corporation for the
     issuance of such Additional Shares of Common Stock. In the event the
     corporation, at any time after the first anniversary of the Series C
     Original Issue Date shall issue Additional Shares of Common Stock
     (including Additional Shares of Common Stock deemed to be issued pursuant
     to paragraph 5D(iv)) without consideration or for a consideration per share
     less than the Series C Conversion Price in effect on the date of and
     immediately prior to such issue, then and in such event, such Series C
     Conversion Price shall be reduced, concurrently with such issue, to the
     price (calculated to the nearest $0.0001) obtained by multiplying the
     Series C Conversion Price in effect immediately prior to the time of such
     issue or sale by a fraction, the numerator of which shall be the sum of (i)
     the number of shares of Common Stock outstanding (or deemed to be
     outstanding hereunder) immediately prior to such issue or sale multiplied
     by the Series C Conversion Price immediately prior to such issue or sale
     plus (ii) the consideration received (or deemed to be received hereunder)
     by the corporation upon such issue or sale, and' the denominator of which
     shall be the product of (iii)

<PAGE>

     the total number of shares of Common Stock outstanding (or deemed to be
     outstanding hereunder) immediately after such issue or sale, multiplied by
     (iv) the Series C Conversion Price immediately prior to such issue or sale.
     Notwithstanding the foregoing, no adjustment of the Series C Conversion
     Price shall be made in an amount less than 50.0001 per share, but any such
     lesser adjustment shall be carried forward and shall be made at the time of
     and together with the next subsequent adjustment which together with any
     adjustments so carried forward shall amount to 50.0001 per share or more.
     Upon each adjustment of the Series C Conversion Price, the Series C
     Preferred Stock shall thereafter be convertible, at the Series C Conversion
     Price resulting from such adjustment, into the number of shares of Class A
     Common Stock obtained by multiplying the Series C Conversion Price in
     effect immediately prior to such adjustment by the number of shares of
     Class A Common Stock into which the Series C Preferred Stock was
     convertible pursuant hereto immediately prior to such adjustment and
     dividing the product thereof by the Series C Conversion Price resulting
     from such adjustment.

          (vii) Determination of Consideration. For purposes of this paragraph
     5D, the consideration received by the corporation for the issuance of any
     Additional Shares of Common Stock shall be computed as follows:

               (a) Cash and Property. Such consideration shall:

                    (1) insofar as it consists of cash, be computed at the
               aggregate amount of cash received by the corporation excluding
               amounts paid or payable for accrued interest or accrued dividends
               after deducting all commissions and expenses paid and concessions
               and discounts allowed to underwriters, dealers or others
               performing similar services in connection with such issue;

                    (2) insofar as it consists of property other than cash, be
               computed at the fair value thereof at the time of such issue, as
               determined in good faith by the Board of Directors; and

                    (3) in the event Additional Shares of Common Stock are
               issued together with other shares or securities or other assets
               of the corporation for consideration that covers both, be the
               proportion of such consideration so received, computed as
               provided in clauses (1) and (2) above, as determined in good
               faith by the Board of Directors.

               (b) Options and Convertible Securities. The consideration per
          share received by the corporation for Additional Shares of Common
          Stock deemed to have been issued pursuant to paragraph 5D(iv),
          relating to Options and Convertible Securities, shall be determined by
          dividing:

<PAGE>

                    (1) the total amount, if any, received or receivable by the
               corporation as consideration for the issue of such Options or
               Convertible Securities, plus the minimum aggregate amount of
               additional consideration (as set forth in the instruments
               relating thereto, without regard to any provision contained
               therein designed to protect against dilution) payable to the
               corporation upon the exercise of such Options or the conversion
               or exchange of such Convertible Securities, or in the case of
               Options for Convertible Securities, the exercise of such Option
               for Convertible Securities and the conversion or exchange of such
               Convertible Securities; by

                    (2) the maximum number of shares of Common Stock (as set
               forth in the instruments relating thereto, without regard to any
               provision contained therein designed to protect against dilution)
               issuable upon the exercise of such Options or the conversion or
               exchange of such Convertible Securities.

     5E. Adjustments for Dividends. Combinations or Subdivisions of Common
Stock. In the event that the corporation at any time or from time to time after
the Series C Original Issue Date shall declare or pay any dividend on the Common
Stock payable in Common Stock or in any right to acquire Common Stock, or shall
effect a subdivision of the outstanding shares of Common Stock into a greater
number of shares of Common Stock (by stock split, reclassification or
otherwise), or in the event the outstanding shares of Common Stock shall be
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares of Common Stock, then the Series A Conversion Prices and Series C
Conversion price in effect immediately prior to such event shall, concurrently
with the effectiveness of such event, be proportionately decreased or increased,
as appropriate.

     5F. Other Distributions. In the event the corporation shall at any time or
from time to time make or issue, or fix a record date for the determination of
holders of Common Stock entitled to receive a dividend or other distribution
payable in securities of other Persons, evidences of indebtedness issued by the
corporation or any of its Subsidiaries or other Persons, assets (excluding cash
dividends) or Options or rights not referred to in paragraph 5D(iv), then in
each such event provision shall be made so that the holders of Series A
Preferred Stock and Series C Preferred Stock shall receive, upon the conversion
thereof, the securities of the corporation that they would have received had
their stock been converted into Common Stock on the date of such event.

     5G. Other Adjustments. In case of any reorganization or any
reclassification of the capital stock of the corporation, any consolidation,
merger or share exchange of the corporation with or into another Person or
Persons (other than a consolidation or merger deemed to be a liquidation,
dissolution or winding up of the corporation as provided in paragraph 2B above),
each share of Series A Preferred Stock and Series C Preferred Stock shall
thereafter be convertible into the number of shares of stock or other securities
or property (including cash) to which a holder of the number of shares of Common
Stock deliverable upon conversion of such share of Series A Preferred Stock or
Series C Preferred Stock would have been entitled upon the record date of (or
date of, if no record date is fixed) such reorganization, reclassification,

<PAGE>

consolidation, merger or share exchange; and, in any case appropriate adjustment
(as determined by the Board of Directors) shall be made in the application of
the provisions herein set forth with respect to the rights and interests
thereafter of the holders of Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock to the end that the provisions set forth herein
shall thereafter be applicable, as nearly equivalent as is practicable, in
relation to any shares of stock or the securities or property (including cash)
thereafter deliverable upon the conversion of the shares of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock.

     5H. No Impairment. The corporation will not, by amendment of these Articles
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the corporation but will at
all times in good faith assist in the carrying out of all the provisions of this
part 5 and in the taking of all such action as may be necessary or appropriate
in order to protect the conversion right of the holders of the Series A
Preferred Stock, the Series B Preferred Stock and the Series C Preferred Stock
against impairment.

     5I. Certificates as to Adjustments. Upon the occurrence of each adjustment
or readjustment of the Series A Conversion Price or Series C Conversion price
pursuant to this part 5, the corporation at its expense shall promptly compute
such adjustment and prepare and furnish to each holder of Series A Preferred
Stock or Series C Preferred Stock, as the case may be, a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The corporation shall, upon the
written request at any time of any holder of the Series A Preferred Stock or
Series C Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Series A Conversion Price or Series C Conversion Price, as the case may be, at
the time in effect, and the number of shares of Common Stock and the amount, if
any, of other property which at the time would be received upon the conversion
of the Series A Preferred Stock or Series C Preferred Stock.

     5J. Issue Taxes. The corporation shall pay any and all issue and other
taxes that may be payable in respect of any issue or delivery of shares of Class
A Common Stock on conversion of shares of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock pursuant hereto; provided, however,
that the corporation shall not be obligated to pay any transfer taxes resulting
from any transfer requested by any holder in connection with any such
conversion.

     5K. Reservation of Stock Issuable Upon Conversion. The corporation shall at
all times reserve and keep available out of its authorized but unissued shares
of Class A Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock, such number of its shares of Class A Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
shares of the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock and if at any time the number of authorized but unissued shares
of Class A Common Stock shall not be sufficient to effect the conversion of all
then outstanding shares of the Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock, the corporation will take such corporate
action as in the opinion of its counsel, may be necessary to

<PAGE>

increase its authorized but unissued shares of Class A Common Stock to such
number of shares as shall be sufficient for such purpose, including, without
limitation, engaging in best efforts to obtain the requisite shareholder
approval of any necessary amendment to these Articles of Incorporation.

     5L. Fractional Shares. No fractional share shall be issued upon the
conversion of any share or shares of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock. All shares of Class A Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock
by a holder thereof shall be aggregated for purposes of determining whether the
conversion would result in the issuance of any fractional share. If, ever such
aggregation, the conversion would result in the issuance of a fraction of a
share of Class A Common Stock, the corporation shall, in lieu of issuing any
fractional share, pay the holder otherwise entitled to such fraction a sum in
cash equal to the fair market value of such fraction on the date of conversion
(as determined in good faith by the Board of Directors of the corporation).

     5M. Payment of Accrued Dividends. As soon as possible after shares of
Series A Preferred Stock or Series C Preferred Stock have been converted into
shares of Class A Common Stock, the corporation shall deliver to the holder of
the shares of Series A Preferred Stock or Series C Preferred Stock converted
payment in cash in an amount equal to all accrued and unpaid dividends with
respect to each share of Series A Preferred Stock or Series C Preferred Stock
converted, or if the conversion occurs following an initial public offering of
the corporation's equity securities, and such securities are then listed on a
national securities exchange or the Nasdaq National Market, at the option of the
corporation, a number of shares of Class A Common Stock having a fair market
value on the date of conversion (based upon the average closing sales prices of
the Class A Common Stock for the immediately preceding ten trading days) equal
to the accrued and unpaid dividends on the shares of Series A Preferred Stock or
Series C Preferred Stock converted. Shares of Class A Common Stock issued by the
corporation in payment of accrued and unpaid dividends in lieu of cash shall,
upon issuance, be fully paid and nonassessable shares.

     5N. Notices. The corporation shall give each holder of record of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock written
notice of each proposed underwritten public offering of Class A Common Stock
that could reasonably be anticipated to be a Qualified Public Offering not later
than 20 days prior to the anticipated date of closing of such public offering.
Such notice shall set forth a summary of the proposed terms of such public
offering, including the anticipated initial public offering price (which may be
expressed as a range of anticipated prices) for the Class A Common Stock.
Thereafter, the corporation shall give such holders prompt written notice of any
material changes in the proposed terms of such public offering, including any
change in the anticipated initial public offering price. If the public offering
is a Qualified Public Offering, the corporation shall also give each holder of
record of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock written notice to such effect, specifying the price at which
shares of Class A Common Stock initially are offered to the public in such
Qualified Public Offering (the "Public Offering Price"), not later than the date
of commencement of such Qualified Public Offering.

Stock, and in the case of any such loss, theft or destruction, upon receipt of
indemnity reasonably satisfactory to the corporation or, in the case of any

will be entitled to convert any and all of the shares o~ such holder's Class B
Common Stock into the same number of shares of Class A Common Stock at such
holder's election; provided, that each holder of Class B Common Stock shall only
be entitled to convert any share or shares of Class B Common Stock to the extent

vote a greater quantity of securities of any kind issued by the corporation than

requirement (and such statement will obligate the corporation to issue such
Class A Common Stock). Such conversion will be deemed to have been effected as
of the close of business on the date on which such certificate or certificates
have been surrendered and such notice has been received, and at such time the
rights of the holder of the converted Class B Common Stock as such holder will
cease and the Person or Persons in whose name or names the certificate or
certificates for shares of Class A Common Stock are to be issued upon such
conversion will be deemed to have become the holder or holders of record of the
shares of Class A Common Stock represented thereby.

<PAGE>

     12C. Promptly after such surrender and the receipt of such written notice,
the corporation will issue and deliver in accordance with the surrendering
holder's instructions (i) the certificate or certificates for the Class A Common

Class B Common Stock which was represented by the certificate or certificates
delivered to the corporation in connection with such conversion but which was

Stock into a greater or lesser number of shares (whether with or without par
value) or a change in the par value of Class A Common Stock or Class B Common
Stock or from par value to no par value, or from no par value to par value) or
in the case of, and as condition to, the consolidation or merger of the
corporation with or into another corporation (other than a merger in which the
corporation is the continuing corporation and which does not result in any
reclassification of outstanding shares of Class A Common Stock or Class B Common
Stock), each share of Class B Common Stock shall be convertible into the number
of shares of stock or other securities or property receivable upon such
reorganization, reclassification, consolidation or merger by a holder of the
number of shares of Class A Common Stock of the corporation into which such
share of Class B Common Stock was convertible immediately prior to such
reorganization, reclassification, consolidation or merger; and, in any such
case, appropriate adjustment shall be made in the application of the provisions
set forth in this paragraph I 2E with respect to the rights and interests
thereafter of the holders of Class B Common stock to the end that the provisions
set forth in this paragraph 1 2E (including provisions with respect to the
conversion rate) shall thereafter be applicable, as nearly as they reasonably
may be, in relation to any shares of stock or other securities or property
thereafter deliverable upon the conversion of the shares of Class B Common
Stock.

     12F. Shares of Class B Common Stock which are converted into shares of
Class A Common Stock as provided herein shall not be reissued.

shares, solely for the purpose of issue upon the conversion of the Class B
Common Stock as provided in this part 12, such number of shares of (T~ass ~
Common Stock as shall then be issuable upon the conversion of all then
outstanding shares of Class B Common Stock (assuming that all such shares of
Class B Common Stock are held by Persons entitled to convert such shares into
Class A Common Stock).

     12H. The issuance of certificates for Class A Common Stock upon the
conversion of Class B Common Stock will be made without charge to the holders of
such shares for any issuance tax in respect thereof or other cost incurred by
the corporation in connection with such conversion and the related issuance of
Class A Common Stock. The corporation will not close its books against the
transfer of Class B Common Stock or of Class A Common Stock issued or

<PAGE>

issuable upon the conversion of Class B Common Stock in any manner which would
interfere with the timely conversion of Class B Common Stock."

               Austin Ventures III will designate two Series A Directors for so

               that Austin Ventures V will designate the Series B Director for

               Series A Directors and the Series B Director, the "Purchaser
               Directors") shall be designated by the holders of a majority of
               the Shares; provided, that Windward will designate the Series C
               Director for so long as Windward holds any Shares;

          (d)  one director shall be James R. Hull ("Hull"), for so long as Hull

meeting) in advance of all meetings of the Board of Directors and all meetings
of committees of the Board of Directors, and will permit such Purchaser, if such
Purchaser has not designated a Purchaser Director, to attend meetings of the

for their actual and reasonable out-of-pocket expenses incurred in attending
meetings of the Board of Directors and all committees thereof and otherwise
incurred in fulfilling their duties as directors. If a Purchaser has not

Purchaser is unable to attend a meeting of the Board of Directors or a committee
on which he serves, the Company shall reimburse one representative of such
Purchaser for actual and reasonable out-of-pocket expenses incurred in attending
meetings of the Board of Directors and such committees. The Company shall also
reimburse one observer designated by Windward for actual and reasonable
out-of-pocket expenses incurred in attending meetings of the Board of Directors

(1) and (n) of the Note Agreement.

     1F. Indemnification Agreements. At the Closing Date under the Series C

director is first elected or appointed to the Board of Directors, the Company

who is elected or appointed to the Board of Directors on such date.

                   2. Provisions Relating to Restricted Stock.

     2A. General Restrictions on Transfer of Capital Stock: Dividends.

          (a) For purposes of this Agreement, "Restricted Stock" is Common Stock
(other than Shares, Underlying Common Stock or Warrant Shares) now owned or
subsequently acquired by any Common Shareholder or a transferee of a Common
Shareholder in a Permitted Transfer (as defined below). During the term of this
Agreement, none of the shares of Restricted Stock may be sold, assigned,
transferred, pledged, encumbered or otherwise disposed of (a "transfer") except
in a Permitted Transfer or a transfer that complies with the provisions of this
Agreement, including paragraph 2B.

          (b) Any attempted transfer of shares of Restricted Stock other than in
accordance with this Agreement shall be null and void and the Company shall
refuse to recognize any such transfer and shall not reflect on its records any
change in record ownership of shares of Restricted Stock pursuant to any such
transfer.

          (c) The following transfers of Restricted Stock (each a "Permitted
Transfer") may be made free of the restrictions and requirements of paragraph 2B
hereof: (i) an individual holder of Restricted Stock may transfer any or all of
the shares of Restricted Stock owned by him to his spouse or children, or to
trusts established for the benefit of his spouse or children, provided that the
transferee grants to the transferor an irrevocable proxy coupled with an
interest to vote all of the shares of Restricted Stock so transferred and agrees
to be bound by the provisions of this Agreement, including, without limitation,
paragraph 2B; (ii) a partnership, corporation or trust holding Restricted Stock
may transfer any shares of Restricted Stock owned by such holder (I) to its
Affiliates, (2) to its general or limited partners, shareholders or
beneficiaries, or (3) to an entity owned by or organized for the benefit of the
general or limited

<PAGE>

partners, shareholders, officers, directors, employees, Affiliates or
beneficiaries of such holder, as applicable, and (iii) a holder of Restricted
Stock may pledge any shares of Restricted Stock owned by such holder to secure
the repayment of any bona fide indebtedness owing by such holder, the Company or
any Subsidiary to a financial institution, provided that such holder retains the
power to vote the shares of Restricted Stock so pledged until such time as the
pledgee shall have realized upon the pledge and that the provisions of this
Agreement, including, without limitation, this part 2 shall be applicable to the
shares of Restricted Stock so pledged. Any Person (other than the Company) who
shall acquire any shares of Restricted Stock in a Permitted Transfer is referred
to in this Agreement as a "Permitted Transferee." Notwithstanding any other
provision of this Agreement, the restrictions and requirements of paragraph 2B
shall not apply to transfers of Restricted Stock pursuant to part 3 hereof.

     2B. Right of First Refusal.

          (a) Whenever and as often as any holder of Restricted Stock desires to
sell any shares of Common Stock pursuant to a bona fide written offer to
purchase such shares, such holder (for purposes of this paragraph 2B, the
"Selling Holder") shall give written notice (the "Notice") to each holder of
Shares, Underlying Common Stock, Warrants or Warrant Shares, each Common
Shareholder and each Permitted Transferee holding Restricted Stock (each, an
"Offeree") to such effect, enclosing a copy of such offer and specifying the
number of shares of Common Stock that the Selling Holder desires to sell, the
name of the Person or Persons to whom the Selling Holder desires to make such
sale and the consideration per share of Common Stock that has been offered in
connection with such offer. Upon receipt of the Notice, the Company shall have
the right and option to purchase the shares proposed to be sold for cash at the
purchase price per share specified in the Notice, exercisable for 20 days after
receipt of the notice. Failure of the Company to respond to such Notice within
such 20-day period shall be deemed to constitute a notification to the Selling
Holder of the Company's decision not to exercise the right and option to
purchase such shares under this paragraph. If the Company fails to exercise its
first right and option, the Selling Holder shall promptly give written notice to
each of the Offerees. The Offerees, pro rata in accordance with their ownership
of Shares, Underlying Common Stock, Warrants (based on the number of Warrant
Shares for which they are then exercisable), Warrant Shares and shares of Common
Stock, calculated on a fully diluted basis, shall have the right and option to
purchase the remaining shares proposed to be sold for cash at the purchase price
per share specified in the Notice, exercisable for 10 days after the
notification of the expiration of the Company's 20-day option period. Failure of
any Offeree to respond to such Notice within such 10-day period shall be deemed
to constitute a notification to the Selling Holder of such Offeree's decision
not to exercise the right and option to purchase such shares under this
paragraph. If any Offeree fails to exercise its first right and option, the
Selling Holder shall give written notice to each of the other Offerees who has
elected to purchase its pro rata share of the shares proposed to be transferred,
and each such Offeree shall have the right, exercisable for a period of five
days from the date of receipt of such notice, to purchase the remaining shares,
pro rata according to Shares, Underlying Common Stock, Warrants (based on the
number of Warrant Shares for which it is then exercisable), Warrant Shares and
shares of Common Stock held by all such electing Offerees, or in such other
proportions as they may agree upon. In the event such consideration includes
non-cash consideration, the dollar value of such non-cash consideration shall be
its fair market value as determined by the Company and the holders of a majority
of the outstanding Shares, Underlying Common Stock, Warrants (based on

<PAGE>

the number of Warrant Shares for which it is then exercisable) and Warrant
Shares ("Fair Market Value"). If such parties are unable to reach an agreement
within 15 days after receipt of the Notice, Fair Market Value will be determined
by an independent appraiser jointly selected by a majority of the Purchaser
Directors and a majority of the remaining directors and the period within which
an Offeree may exercise its right or option under this paragraph shall be
extended until 10 days after such appraisal is completed.

          (b) The Company and/or the Offerees may exercise the right and option
provided above by giving written notice of exercise to the Selling Holder within
such 10-day period, specifying the date (not later than five days from the date
of expiration of all applicable first right and options to purchase shares under
this paragraph) upon which payment of the purchase price for the shares
purchased pursuant to this paragraph shall be made. The Selling Holder shall
deliver to the Offeree(s) at the Company's principal office, one day prior to
the payment date, wire transfer instructions, and on the payment date specified
in such notice, the certificate or certificates representing such shares,
properly endorsed for transfer, against payment of the purchase price therefor
by the Offeree(s) in immediately available funds.

          (c) If all the shares proposed to be transferred are not purchased by
Offerees in accordance with this paragraph, the Selling Holder shall not be
required to sell any of the shares proposed to be transferred to the Offerees or
to the Company, and during the 90-day period commencing on the expiration of the
rights and options provided for in this paragraph, may sell all (but not less
than all) of such shares to the transferee named in Notice for a consideration
equal to or greater than the consideration specified in the Notice, free of the
restrictions contained in paragraph 2B of this Agreement (but subject to the
other terms and conditions hereof).

          (d) For the purposes of calculating the number of shares an Offeree
may acquire under this paragraph 2B, options to acquire Common Stock pursuant to
the Company's 1994 Stock Plan held by an Offeree shall be deemed issued and
outstanding if such Offeree is then an employee of the Company.

     2C. Contractual Preemptive Rights. Notwithstanding any preemptive or
similar rights that any of the parties hereto may have pursuant to any other
agreement, the parties hereto agree that their respective preemptive or similar
rights with respect to the issuance of Equity Securities by the Company after
the date hereof shall be governed exclusively by this paragraph 2C. If prior to
a Qualified Public Offering (as defined below), the Company shall issue any
Equity Securities, each holder of Shares, Underlying Common Stock and Warrant
Shares and the Hull Family Limited Partnership (the `Hull Partnership") shall be
entitled to purchase, on the same terms, the same proportion of such Equity
Securities to be issued necessary in order that the aggregate shares of Common
Stock beneficially held by such holder constitute the same percentage of all
Common Stock (assuming, in each case, the conversion, exercise or exchange of
all outstanding Equity Securities, including outstanding Equity Securities held
by such holder) after the issuance of such Equity Securities as before the
issuance thereof; provided, however, that such preemptive right shall not apply
to (a) securities issued to employees or consultants to the Company under the
1994 Stock Plan, (b) securities issued upon the conversion, exercise or exchange
of Equity Securities to which the preemptive rights under this paragraph 2C were
applicable, (c) securities issued in connection with an exercise of the
preemptive rights granted

<PAGE>

hereunder, (d) Shares issued pursuant to the Series C Purchase Agreement,
including Shares issued upon conversion of the Series C Preferred Stock, (e)
securities issued upon exercise of the Warrants, (f) securities issued in
connection with the merger with or acquisition of another Person, (g) securities
issued in connection with a public offering, or (h) shares of Class A Common
Stock issued as dividends on Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock pursuant to the Articles of Incorporation. A holder
of Shares, Underlying Common Stock and Warrant Shares and the Hull Partnership
may exercise his or its right under this paragraph 2C to purchase Equity
Securities by paying the purchase price therefor at the principal office of the
Company within 20 days after receipt of notice from the Company (which notice by
the Company shall be given at least 20 days before the issuance of the Equity
Securities) stating the amount of Equity Securities it intends to issue and the
price and characteristics thereof. The holder shall pay such purchase price in
cash or by check; provided, however, that if the Company is indebted to such
holder, the holder shall be entitled, at the holder's sole option, to credit
against the purchase price all or any portion of the Company's indebtedness to
such holder which is then due (accrued and unpaid dividends on any Preferred
Stock shall be deemed to be indebtedness for purposes of such credit). A
holder's contractual preemptive rights hereunder shall be deemed to be exercised
immediately prior to the close of business on the day of payment of the purchase
price in accordance with the foregoing provisions, and at such time such holder
shall be treated for all purposes as the record holder of the Equity Securities,
as the case may be. As promptly as practicable (and i: any event within ten
days) on or after the purchase date, the Company shall issue and deliver at its
principal office a certificate or certificates for the number of full shares or
amount, whichever is applicable, of Equity Securities together with cash for any
fraction of a share or portion of an Equity Security at the purchase price to
which the holder is entitled hereunder. For purposes of this paragraph 2C,
"Qualified Public Offering" shall mean the sale of the corporation's Class A
Common Stock in a firm commitment, underwritten public offering registered under
the Securities Act (other than a registration relating solely to a transaction
under Rule 145 under the Securities Act (or any successor thereto) or to an
employee benefit plan of the corporation), at a public offering price (prior to
underwriters commissions and expenses) per share of Class A Common Stock
(appropriately adjusted for subdivisions and combinations of shares of Common
Stock and dividends on Class A Common Stock payable in shares of Class A Common
Stock) equal to or exceeding $3.00 per share.

     2D. Purchasers or Transferees of Capital Stock. Except as otherwise
specifically provided herein, any Permitted Transferee or other Person who shall
acquire (either voluntarily or involuntarily, by operation of law or otherwise)
any shares of Restricted Stock or any other security subject to the terms of
this Agreement shall be bound by all the terms and conditions of this Agreement
to the same extent as the parties hereto and, prior to registration of the
transfer of any such securities on the books of the Company, any purchaser or
other transferee shall execute an agreement with the parties hereto agreeing to
be bound hereby.

                   3. Liquidity Rights~ Right of First Offer.

     3A. Sale of the Company. If the Company fails (for any reason, including
that the funds of the Company legally available to make such Mandatory
Redemption are insufficient) to redeem any shares of Preferred Stock in a
Mandatory Redemption on the Mandatory Redemption Date (such date determined
without giving effect to Article IV, paragraph 3M of the Articles of

<PAGE>

Incorporation) the holders of a majority of the outstanding shares of any series
of Preferred Stock may elect, by giving written notice to that effect to the
Company within 45 days after such Mandatory Redemption Date to defer such
Mandatory Redemption for 12 months and to initiate procedures for the Sale of
the Company (the "Sale Notice"). For purposes hereof, a "Sale of the Company"
means either (i) a sale of all or substantially all of the issued and
outstanding stock of the Company, (ii) a sale of all or substantially all of the
assets and business of the Company and a liquidation of the Company immediately
following such sale, or (iii) a merger or consolidation of the Company with or
into another corporation, in each case for cash or securities. If the Sale
Notice is issued, all holders of Preferred Stock shall be deemed to have so
deferred and the following procedure shall apply.

     3B. Sale Procedure. The Board of Directors shall, as promptly as
practicable, engage a Qualified Investment Banker (as defined below) at the
Company's expense to represent the Company and the shareholders of the Company
in connection with the Sale of the Company. The Company and the Common
Shareholders shall use their reasonable best efforts to consummate the Sale of
the Company within 90 days after receipt of the Sale Notice or as soon as
possible thereafter, but shall not be required to solicit offers for more than
nine months following the date that the Qualified Investment Banker begins such
solicitation. For purposes hereof, a "Qualified Investment Banker" shall be a
nationally recognized investment banking firm selected by the Board of Directors
of the Company with a majority of the Purchaser Directors concurring.

     3C. Sale Offers. At such time as the Company suspends its solicitation of
offers for the Sale of the Company, it shall give each holder of Preferred Stock
written notice ("Offer Notice") describing each offer (each a "Sale Offer")
received by the Company, setting forth the name of the proposed purchaser, a
description of the consideration to be received upon the sale, the date for
closing the sale and the other material terms of the Sale Offer. The holders of
a majority of the outstanding Preferred Stock may select one Sale Offer by
giving written notice of such selection to the Company within 15 days following
receipt of the Offer Notice.

     3D. Acceptance. Notice of the Sale Offer selected by the holders of
Preferred Stock pursuant to paragraph 3C above shall be given by the Company to
each Common Shareholder and each holder of Warrants and Warrant Shares. Within
60 days following receipt of notice of such selection, the Company, (or, if the
selected Sale Offer is an offer to purchase capital stock of the Company, the
Common Shareholders), must accept the selected Sale Offer.

     3E. Purchase and Sale. If a Sale Offer is made, the Company or, if the Sale
Offer is to purchase shares of capital stock of the Company, each Common
Shareholder, shall sell the assets and business of the Company or shares of
capital stock of the Company, as the case may be, on the terms set forth in the
Sale Offer.

     3F. Best Efforts. The Company and each Shareholder agree to use reasonable
best efforts to cause the Company to effect a Sale of the Company pursuant to
any Sale Offer accepted by the Company, including, without limitation, voting
all shares of voting stock held by such Shareholder to approve a sale of assets
by the Company followed by the liquidation and dissolution of the Company, or to
adopt a plan of merger or consolidation by the Company included in the terms of
such Sale Offer.

<PAGE>

     3G. Lapse. If all parties to this Agreement have performed their
obligations under this part 3 and if the Sale of the Company is not consummated
within 12 months after such Mandatory Redemption Date through no fault of the
Company, the right herein granted to effect a Sale of the Company by reason of
the failure of the Company to redeem shares of Preferred Stock on such Mandatory
Redemption Date shall lapse.

     3H. Right of First Offer. Prior to entering into any Sale of the Company in
which holders of Series C Preferred Stock would receive less than the Series C
Conversion Price then in effect, the Company will first give Windward written
notice that the Company is contemplating a Sale of the Company and Windward will
have the right to make an offer to purchase the Company in accordance with this
paragraph 3H. Such right of offer to purchase shall be exercisable for a period
of 30 days after Windward receives written notice from the Company of its intent
to pursue a Sale of the Company. At any time during the period set forth above,
Windward may deliver to the Company a written proposal for the purchase of the
Company. Such proposal will disclose in reasonable detail the terms and
conditions upon which Windward will agree to purchase the Company in a Sale of
the Company, including the securities or assets to be acquired and the price to
be paid. The Company may either accept the offer of Windward or pursue
alternative Sale of the Company transactions; provided, however, that the
Company may not consummate any alternative Sale of the Company unless the
consideration per share to be received in such Sale of the Company is at least
110% of the consideration per share proposed by Windward. Nothing in this part 3
shall be deemed to prevent the Company from engaging in an initial public
offering of its securities during the time a Sale of the Company is being
sought.

                             4. General Provisions.

     4A. Transfer Conditions. Prior to any proposed sale, assignment, transfer
or pledge of any Preferred Stock, Warrants, Warrant Shares or Common Stock
(other than a transfer not involving a change in beneficial ownership), unless
there is in effect a registration statement under the Securities Act covering
the proposed transfer, the holder thereof shall give notice to the Company of
such holder's intention to effect such transfer, sale, assignment or pledge.
Each such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in reasonable detail, and, if requested by
the Company, shall be accompanied, at such holder's expense, by either (i) a
written opinion of legal counsel who shall be, and whose legal opinion shall be,
reasonably satisfactory to the Company (it being agreed that Testa, Hurwitz &
Thibeault, LLP, Hughes & Luce, L.L.P. and Skadden, Arps, Slate, Meagher & Flom
LLP are satisfactory counsel), addressed to the Company, to the effect that the
proposed transfer of the Preferred Stock, Warrants, Warrant Shares or Common
Stock may be effected without registration under the Securities Act, or (ii) a
"no action" letter from the Securities and Exchange Commission (the
"Commission") to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Preferred Stock, Warrants, Warrant Shares or Common Stock shall be entitled to
transfer such Preferred Stock, Warrants, Warrant Shares or Common Stock in
accordance with the terms of the notice delivered by the holder to the Company
and subject to the other provisions of this Agreement. Each certificate
evidencing the Preferred Stock, Warrants, Warrant Shares or Common Stock
transferred as provided above shall bear, except if such transfer is made
pursuant to Rule 144 under the Securities Act, the appropriate restrictive
legend set forth below, except that such

<PAGE>

certificate shall not bear such restrictive legend if in the opinion of counsel
for such holder and the Company such legend is not required in order to
establish compliance with any provision of the Securities Act. Notwithstanding
the foregoing, each holder of Preferred Stock, Warrants, Warrant Shares or
Common Stock agrees that it will not request that a transfer of the Preferred
Stock, Warrants, Warrant Shares or Common Stock be made (or that the appropriate
restrictive legend described below hereof be removed from the certificate
evidencing the Preferred Stock, Warrants, Warrant Shares or Common Stock) solely
in reliance on Rule 144(k) under the Securities Act, if as a result of such
proposed transfer the Company would be rendered subject to the reporting
requirements of the Securities Exchange Act.

     4B. Legends on Certificates. During the term of this Agreement, each
certificate representing shares of Common Stock, Warrant Shares or Preferred
Stock will bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE AND THE SALE, ASSIGNMENT,
     TRANSFER, PLEDGE OR OTHER DISPOSITION AND VOTING THEREOF ARE SUBJECT TO
     CERTAIN RESTRICTIONS AND AGREEMENTS CONTAINED IN A SECOND AMENDED AND
     RESTATED SHAREHOLDERS AGREEMENT DATED AS OF MARCH --, 1999 AMONG THE
     COMPANY AND CERTAIN SHAREHOLDERS AND WARRANT HOLDERS. A COPY OF THE
     SHAREHOLDERS AGREEMENT AND ALL APPLICABLE AMENDMENTS THERETO WILL BE
     FURNISHED BY THE COMPANY TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT
     CHARGE UPON WRITTEN REQUEST TO THE COMPANY AT ITS PRINCIPAL PLACE OF
     BUSINESS OR REGISTERED OFFICE."

The Company shall make a notation on its records and give instructions to any
transfer agent of the Preferred Stock, Warrants, Warrant Shares or Common Stock
in order to implement the restrictions on transfer established in this
Agreement.

     4C. Termination; Amendment.

          (a) This Agreement shall terminate upon the earlier to occur of (i)(A)
the written agreement of the holders of at least 662/3% of the Shares then
outstanding, (B) the holders of at least 662/3% of the Underlying Common Stock
then outstanding and (C) the holders of at least 662/3% of the Common Stock
issued and issuable upon exercise of the Warrants, (ii) the acquisition by a
single purchaser of all of the issued and outstanding shares of the Common
Stock, Shares, Warrants, Warrant Shares and the Underlying Common Stock or (iii)
the closing of a Qualified Public Offering.

          (b) This Agreement may be amended by the written agreement of the
holders of at least 662/3% of the shares of Restricted Stock, at least 662/3% of
the shares of Underlying Common Stock, and, in the case of any amendment that
adversely affects the rights or interests of any holder or holders of Warrants
or Warrant Shares hereunder, at least 662/3 of the Common Stock issued and
issuable upon exercise of the Warrants, and, in the case of any amendment that
adversely affects the rights or interests of any holder or holders of Shares
hereunder, at least 662/3 of the Shares.

of the State of Texas or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the State of Texas.

     4F. Counterparts. This Agreement may be executed in my number of

                       EXHIBIT A TO SHAREHOLDERS AGREEMENT

                            INDEMNIFICATION AGREEMENT

     This Indemnification Agreement (the "Agreement") is executed on and entered
into as of              --,       (the "Effective Date") by and between
           ------------     -----
Monitronics International, Inc., a Texas corporation (the "Company"), and
                   ("Director").
------------------

     The Company is required or permitted under certain circumstances to
indemnify directors of the Company against liability incurred by them in such
capacities or by reason of occupying such position. The Company desires to have
Director serve as a director of the Company, and Director desires to serve,
provided that he is indemnified by the Company. This is the Indemnification
Agreement referred to in the Second Amended and Restated Shareholders Agreement
(the "Shareholders Agreement") entered into on March , 1999 by the Company and
the Shareholders named therein.

     The parties agree as follows:

                                 1. Definitions.

     Unless the context requires otherwise, for purposes of this Agreement:

     (a) "Act" shall mean the Texas Business Corporation Act, as in effect on
the date of this Agreement and as hereafter amended, and any successor statute;

     (b) the terms "proceedings," "expenses" and other terms defined in Article
2.02-i of the Act are used herein with the meanings as so defined under the Act;
and

     (c) the phrase "serving in a representative capacity at the request of the
Company" means serving at the request of the Company as a director, officer,
partner, venturer, proprietor, trustee, employee, agent or similar functionary
of another corporation, partnership, joint venture, sole proprietorship, trust,
employee benefit plan or other enterprise.

                                  2. Indemnity.

     (a) The Company agrees to indemnify Director to the fullest extent
permitted by the Act, as soon as practicable but in any event no later than 30
days after receipt by the Company of any claim for indemnity hereunder against
expenses judgments, penalties, fines and amounts paid in settlement (including
all interest, assessments and other charges paid or payable in connection with
or in respect of such expenses, judgments, fines, penalties or amounts paid in
settlement of such proceeding) incurred by or on behalf of Director in
connection with any proceeding in which Director was, is or is threatened to be
a named a party to or witness or other participant in such proceeding because he
is or was a director or officer of the Company or because he is or was serving
in a representative capacity at the request of the Company.

     (b) Reasonable expenses incurred by Director in connection with a
proceeding referred to in paragraph 2A in advance of the final disposition of
the proceeding and without the

<PAGE>

determination specified in Sections F or G of Article 2.02-1 of the Act,
promptly upon receipt by the Company of:

          (i) a written affirmation by Director of his good faith belief that he
has met the standard of conduct necessary for indemnification under the Act; and

          (ii) a written undertaking by or on behalf of the Director to repay
the amount paid or reimbursed pursuant to this paragraph 2B if it is ultimately
determined that he has not met the standard of conduct necessary for
indemnification under the Act or if it is ultimately determined that
indemnification of Director against expenses incurred by him in connection with
that proceeding is prohibited by Section E of Article 2.02-I of the Act.

     (c) This Agreement makes mandatory the indemnification permitted under
Section B of Article 2.02-1 of the Act with respect to expenses incurred in
connection with a proceeding described in such provision and shall be deemed to
constitute authorization of indemnification in the manner required by the Act.

                      3. Notification and Defense of Claim.

     (a) Promptly after receipt by Director of notice of the commencement of any
proceeding in which Director was, is or is threatened to be a named a party to
or witness or other participant in such proceeding, if a claim for indemnity in
connection with such proceeding is to be made against the Company under this
Agreement, will promptly notify the Company of the commencement thereof. With
respect to any such proceeding other than a proceeding brought by or on behalf
of the Company or as to which Director shall have made the determination
provided for in (ii) below, the Company will be entitled to participate therein
at its own expense, and the Company may assume the defense thereof with counsel
satisfactory to Director. After notice from the Company to Director of its
election to assume the defense thereof, the Company will not be liable to
indemnify Director under this Agreement against expenses subsequently incurred
by Director in connection with the defense thereof other than reasonable costs
of investigation or as otherwise provided below. Director shall have the right
to select and employ counsel in a proceeding, but the fees and expenses of such
counsel incurred after notice from the Company of its assumption of the defense
thereof shall be borne by Director unless (i) the employment of such counsel by
Director has been authorized by the Company, (ii) Director shall have reasonably
concluded that there may be a conflict of interest between the Company and
Director in the conduct of the defense of such proceeding, or (iii) the Company
shall not in fact have employed counsel to assume the defense of such action,
and in each case the fees and expenses of counsel shall be subject to the
indemnity provided hereunder by the Company; provided, however, that in the
event any other person indemnified by the Company is also named or threatened to
be named defendant or respondent in a proceeding referred to in (ii) above, the
fees and expenses of only one counsel employed by Director and all such other
persons shall be subject to indemnity hereunder.

     (b) Promptly following receipt by the Company from Director of any claim
for indemnity hereunder, the Company shall in good faith make or cause to be
made any determination as to reasonableness of expenses and determination that
indemnification is permissible as may be required pursuant to the Act and, as
soon as practicable, but in any event

<PAGE>

no later than 30 days after receipt by the Company of any claim for indemnity
hereunder, following such determination, the Company shall pay or cause to be
paid to Director in cash the amount of the expenses indemnified hereunder and so
determined to be reasonable and permissible. Such payment shall be~ made out of
the assets of the Company.

                                4. Miscellaneous.

     (a) The Company expressly confirms and agrees that it has entered into this
Agreement in order to induce Director to serve or continue to serve as a
director or in a representative capacity at the request of the Company, and
acknowledges that Director is relying upon this Agreement in continuing in such
capacity and in serving as a director of the Company or in a representative
capacity at the request of the Company hereafter, whether or not Director serves
in any such capacity on the date of this Agreement. All agreements and
obligations of the Company contained herein shall continue during the period
that Director serves as a director of the Company or in a representative
capacity at the request of the Company and thereafter so long as Director shall
be subject to any possible claim or pending, threatened or completed proceeding
by reason of the fact that Director was a director or served in any other
representative capacity.

     (b) In the event Director is required to bring any action to enforce his
rights or to collect any amount due him under this Agreement and is successful
in such action, the Company shall reimburse Director for all of Director's fees
and expenses (including, without limitation, reasonable attorney's fees) in
bringing and pursuing such action.

     (c) Each of the provisions (including any provision within a single
paragraph or sentence) of this Agreement is a separate and distinct agreement
and independent of the others, so that if any provision hereof shall be held to
be invalid, illegal or unenforceable for any reason whatsoever, such invalidity
or unenforceability shall not affect the validity or enforceability of the other
provisions hereof and such remaining provisions shall remain enforceable to the
fullest extent permitted by law.

     (d) This Agreement shall be interpreted and enforced in accordance with the
internal laws but not the law of conflicts of the State of Texas.

     (e) This Agreement and the terms hereof shall be binding upon and inure to
the benefit of the Company and Director, and their respective successors and
assigns.

     (f) No amendment, modification, termination or cancellation of this
Agreement shall be effective unless in writing signed by both parties hereto. No
waiver of any of the provisions of this Agreement shall be deemed or shall
constitute a waiver of any other provisions hereof (whether or not similar) nor
shall such waiver constitute a continuing waiver.

     (g) The-indemnification provided by this Agreement shall not be deemed
exclusive of any other rights to which Director may be entitled under any
provision of the Act, the Articles of Incorporation or bylaws of the Company or
of any other corporation, or any other agreement or otherwise. To the extent
that a change in the Act (whether by statute or judicial decision) permits
greater indemnification by agreement than would be affording currently under the
Company's bylaws and this Agreement, it is the intent of parties hereto that
Director shall enjoy by this Agreement the greater benefits so afforded by such
change.

     The parties hereto desire to amend and restate the Prior Registration
Agreement in its entirety in order to facilitate the transactions contemplated

     The parties agree that the Prior Registration Agreement shall be amended
and restated in its entirety by this Agreement, and the parties further agree as
follows:

     1.   Demand Registrations.

          (a)  Requests for Registration

               (i) At any time and from time to time (A) after March   , 2000,
                                                                     --
the holders of at least 66-2/3% of the shares of Common Stock issued or issuable
upon conversion of the Series A Preferred Stock and the Series C Preferred Stock
(the "Underlying Common Stock") and (B) at any time and from time to time
following the initial public offering of the Company's equity securities, the
holders of at least 66-2/3% of the shares of Common Stock issued or issuable
upon conversion of the Series C Preferred Stock (each of the groups described in
(A) and (B), a "Demand Registrant"), may request registration under the
Securities Act of all or any part of their Underlying Common Stock (each, a
"Demand Registration"), subject to the terms and conditions of this Agreement.
Any request (a "Registration Request") for a Demand Registration shall specify
(i) the approximate number of shares of Underlying Common Stock requested to be
registered (but not less than a majority of the total number of shares of
Underlying Common Stock issued or issuable to the Demand Registrant), and (ii)
the intended method of distribution of such shares that will be a firm
commitment underwritten offering managed by one or more underwriters selected as
provided in paragraph 1(b), below. Within ten days after the date of sending of
such request, the Company will give written notice of such requested
registration to all other holders of Underlying Common Stock and to all holders
of Warrants and Warrant Shares and will (subject to clause (iii) below) include
in such registration all shares of Underlying Common Stock and all Warrant
Shares that holders of Underlying Common Stock, Warrants or Warrant Shares
request the Company to include in such registration by written notice given to
the Company within 15 days after the date of sending of the Company's notice.

               (ii) Subject to paragraph l(a)(i), the holders of 66-2/3% of the
Underlying Common Stock will be entitled to request up to two Demand
Registrations at any time and from time to time after March , 2000 and the
holders of the shares of Common Stock issued or issuable upon conversion of the
Series C Preferred Stock will be entitled to request up to two Demand
Registrations at any time and from time to time after the initial public
offering of the Company's equity securities. A Demand Registrant requesting a
Demand Registration under this part 1 may, at any time prior to the effective
date of the registration statement relating to such Demand Registration, revoke
such request by providing written notice thereof to the Company, in which case
such Demand Registration will not be deemed to have been requested for purposes
of this paragraph l(a)(ii). Any Demand Registration requested by a Demand
Registrant shall not be deemed to have been effected (and, therefore, not
requested for purposes of this paragraph l(a)(ii)) unless it has become
effective and there has not been any stop order,

<PAGE>

injunction or other order or requirement of the Securities and Exchange
Commission (the "Commission") or other governmental agency or court suspending
such effectiveness.

               (iii) Subject to the provisions of the Heller Warrant, the
Company will not include in any Demand Registration any securities other than
Underlying Common Stock and Warrant Shares of the Demand Registrant without the
prior written consent of the Demand Registrant, except that the Company shall
include in such registration shares of Common Stock to be sold for the account
of the Company, for the account of other holders of Underlying Common Stock and
for the account of other holders of Warrants and Warrant Shares if the managing
underwriter(s) advise the Company in writing that in their opinion the shares of
Underlying Common Stock, Warrant Shares and other shares of Common Stock
proposed to be included in such offering can be sold in an orderly manner in
such offering within a price range acceptable to the Demand Registrant If the
managing underwriter(s) advise the Company in writing that in their opinion the
number of shares of Underlying Common Stock, Warrant Shares and shares of Common
Stock proposed to be included in such registration for sale by the Company,
Heller, holders of Warrants and Warrant Shares and holders of Underlying Common
Stock exceeds the number of shares which can be sold in an orderly manner in
such offering within a price range acceptable to the Demand Registrant, the
Company will include in such registration, prior to the inclusion of any other
shares, (i) first, the Issued Warrant Shares (as defined in the Heller Warrant),
(ii) second, the number of shares of Underlying Common Stock and Warrant Shares
requested to be registered by the Demand Registrant, and (iii) third, the number
of other shares of Underlying Common Stock and Warrant Shares requested to be
included that in the opinion of such underwriters can be sold in an orderly
manner within the price range of such offering, pro rata among the respective
holders thereof on the basis of the number of shares of Underlying Common Stock
and Warrant Shares that each such holder has requested the Company to include in
such registration. For purposes of this paragraph 1(a)(iii), in any Demand
Registration in which the Demand Registrant is the holders of 66-2/3% of the
Underlying Common Stock, all Warrant Shares requested to. be registered in the
Demand Registration shall be deemed to be requested by the Demand Registrant.

               (iv) In the event that in connection with an initial public
offering, the managing underwriter(s) advise the Company in writing that in
their opinion Underlying Common Stock and Warrant Shares can be included in a
secondary portion of such registration, then the Company shall advise all
shareholders in accordance with paragraph 1(i) above and shall include in such
registration all shares of Underlying Common Stock and all Warrant Shares that
holders of Underlying Common Stock, Warrants or Warrant Shares request the
Company to include in such registration; provided that, if the managing
underwriter(s) advise the Company in writing that in their opinion the number of
shares of Underlying Common Stock and Warrant Shares proposed to be included in
such registration exceeds the number of shares which can be sold in an orderly
manner in such offering within a price range acceptable to the Company, the
Company will include in such registration the number of shares that in the
opinion of such underwriters can be sold, subject to the terms of the Heller
Warrant, pro rata among the respective holders thereof on the basis of the
number of shares of Underlying Common Stock and Warrant Shares that each such
holder has requested the Company to include in such registration.

<PAGE>

          (b) Selection of Underwriter. The Demand Registrant shall select the
managing underwriter(s) to manage each offering effected pursuant to a Demand
Registration.

          (c) Registration on Forms S-2, S-3. Following its initial public
offering of securities under the Securities Act, the Company shall use its
commercially reasonable best efforts to qualify for registration on Forms S-2 or
S-3 or any comparable or successor form or forms. After the Company has
qualified for the use of Forms S-2 or S-3 or any comparable or successor form of
forms, in addition to the rights contained in the paragraphs 1(a) and (b), each
of (i) the holders of at least 25% of the Underlying Common Stock, (ii) the
holders of at least 30% of the Common Stock issued and issuable upon exercise of
the Warrants and (iii) holders of a majority of the shares of Common Stock

million; provided further, that the Company shall not be obligated to effect
more than two Registrations on Form S-2 or S-3 or any comparable or successor
form or forms during any twelve month period. Such requests shall be in writing

Shares, as applicable, proposed to be disposed of and the intended method of
distribution of such shares by such holder or holders.

effect any registration within 180 days after the effective date of a previous
registration statement on Form S-I in which the holders of Underlying Common
Stock participated or were given an opportunity to participate and declined to
do so. The Company may postpone for up to 180 days the filing or the
effectiveness of a registration statement for a Demand Registration set forth
above if (i) the Board of Directors determines, reasonably and in good faith,
that such registration might have an adverse effect on any proposal or plan by
the Company, including, without limitation, a plan or proposal to engage in any
acquisition, merger, consolidation, tender offer, offering or similar
transaction or (ii) any other material, nonpublic development or transaction is
pending; provided, that the Company may not postpone the filing or effectiveness
of a registration statement pursuant to this sentence more frequently than once
during any period of 12 consecutive months.

          (a) Right to Piggyback. If the Company proposes to register any of its
securities under the Securities Act (other than pursuant to a Demand
Registration or registration solely in connection with an employee benefit or
stock ownership plan) and the registration form to be used may be used for the
registration of Underlying Common Stock and/or Warrant Shares (a "Piggyback
Registration"), the Company will give prompt written notice to all holders of
Underlying Common Stock and to all holders of Warrants and Warrant Shares of its
intention to effect such a registration (each a "Piggyback Notice"). Subject to
subparagraph 2(c) below and the provisions of the Heller Warrant, the Company
will include in such registration all shares of Underlying Common Stock that
holders of Underlying Common Stock and all Warrant Shares that holders of
Warrants and Warrant Shares request the Company to include in such registration

<PAGE>

the Piggyback Notice.

          (b) Piggyback Expenses. The Registration Expenses of the holders of
Underlying Common Stock and the holders of Warrant Shares will be paid by the
Company in all Piggyback Registrations.

          (c) Priority on Primary Registrations. If a Piggyback Registration
relates to an underwritten public offering of equity securities by the Company
and the managing underwriters advise the Company in writing that in their
opinion the number of securities requested to be included in such registration
exceeds the number that can be sold in an orderly manner in such offering within
a price range acceptable to the Company, the Company will include in such
registration (i) first, the securities proposed to be sold by the Company, (ii)
second, the Issued Warrant Shares (as defined in the Heller Warrant), (iii)
third, the Underlying Common Stock and Warrant Shares requested to be included
in such registration, pro rata among the holders of such Underlying Common Stock
and Warrant Shares on the basis of the number of shares owned by each such
holder and (iv) fourth, other securities requested to be included in such
registration.

          (d) Priority on Secondary Registrations. If a Piggyback Registration
relates to an underwritten public offering of equity securities by holders of
the Company's securities and the managing underwriters advise the Company in
writing that in their opinion the number of securities requested to be included
in such registration exceeds the number which can be sold in an orderly manner
in such offering within a price range acceptable to the holders initially
requesting such registration, the Company will include in such registration (i)
first, the Issued Warrant Shares, (ii) second, the securities requested to be
included therein by the holders requesting such registration, (iii) third, the
Underlying Common Stock and Warrant Shares requested to be included in such
registration, pro rata among the holders of such Underlying Common Stock and
Warrant Shares on the basis of the number of shares owned by each such holder
and (iv) fourth, other securities requested to be included in such registration.

     3. Registration Procedures. Whenever the holders of Underlying Common
Stock, Warrants or Warrant Shares have requested that any Underlying Common
Stock or Warrant Shares be registered pursuant to this Agreement, the Company
will use its best efforts consistent with legal requirements and, in the case of
an offering by the Company, prevailing market conditions, to effect the
registration and the sale of such Underlying Common Stock and/or Warrant Shares,
as applicable, in accordance with the intended method of distribution thereof
and will as expeditiously as possible:

          (i) prepare and file with the Commission a registration statement with
respect to such Underlying Common Stock and/or Warrant Shares, as applicable,
and use its best efforts to cause such registration statement to become
effective, provided that before filing a registration statement or prospectus or
any amendments or supplements thereto, the Company will furnish to the selling
shareholders' counsel selected by the holders of a majority of an aggregate of
the Underlying Common Stock and Warrant Shares covered by such registration
statement in the case of a Piggyback Registration and to counsel selected by the
Demand Registrant in the case of

<PAGE>

a Demand Registration copies of all such documents proposed to be filed, which
documents will be subject to the review of such counsel;

          (ii) prepare and file with the Commission 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 for
a period of up to six months, and comply with the provisions of the Securities
Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of distribution by the sellers thereof set forth in such registration
statement;

          (iii) furnish to each seller of Underlying Common Stock and Warrant
Shares, as applicable, 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 such other
documents as such seller may reasonably request in order to facilitate the
disposition of the Underlying Common Stock and/or Warrant Shares, as applicable,
owned by such seller;

          (iv) use its best efforts to register or qualify such Underlying
Common Stock and/or Warrant Shares, as applicable, under such other securities
or blue sky laws of such jurisdictions as any seller reasonably requests and do
any and all other acts and things which may be reasonably necessary or advisable
to enable such seller to consummate the disposition in such jurisdictions of the
Underlying Common Stock and/or Warrant Shares, as applicable, owned by such
seller, provided that Life Company will not be required (i) to qualify generally
to do business in any jurisdiction where it would not otherwise be required to
qualify but for this subparagraph, (ii) to subject itself to taxation in any
such jurisdiction or (iii) to consent to general service of process in any such
jurisdiction;

          (v) notify each seller of such Underlying Common Stock and/or Warrant
Shares, as applicable, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration statement
contains an untrue statement of a material fact or omits any fact necessary to
make the statements therein not misleading, and, at the request of any such
seller, the Company will prepare a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Underlying Common Stock
and/or Warrant Shares, as applicable, such prospectus will not contain an untrue
statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading;

          (vi) cause all such Underlying Common Stock and/or Warrant Shares, as
applicable, to be listed for trading on each securities exchange on which
similar securities issued by the Company are then listed and to be qualified for
trading on each system on which similar securities issued by the Company are
from time to time qualified;

          (vii) provide a transfer agent and registrar for all such Underlying
Common Stock and/or Warrant Shares, as applicable, not later than the effective
date of such registration statement and thereafter maintain such a transfer

<PAGE>

agreements in customary form) and take all such other actions as the holders of
a majority of the aggregate of the shares of Underlying Common Stock and Warrant
Shares being sold or the underwriters, if any, reasonably request in order to
expedite or facilitate the disposition of such Underlying Common Stock and/or
Warrant Shares, as applicable;

          (ix) make available for inspection by any underwriter participating in
any disposition pursuant to such registration statement and any attorney,
accountant or other agent retained by any such underwriter, all financial and
other records, pertinent corporate documents and properties of the Company, and
cause the Company's officers, directors, employees and independent accountants
to supply all information reasonably requested by any such underwriter,
attorney, accountant or agent in connection with such registration statement;

          (x) otherwise use its best efforts to comply with all applicable rules
and regulations of the Commission, and make available to its security holders,
as soon as reasonably practicable, an earnings statement covering the period of
at least twelve months beginning with the first day of the Company's first full
calendar quarter after the effective date of the registration statement, which
earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder;

          (xi) permit any holder of Underlying Common Stock and/or Warrant
Shares, as applicable, which might be deemed, in the sole and exclusive judgment
of such holder, to be an underwriter or a controlling person of the Company, to
participate in the preparation of such registration or comparable statement and
to require the insertion therein of material, furnished to the Company in
writing, which in the reasonable judgment of such holder and its counsel should
be included; and

          (xii) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Underlying Common Stock and/or Warrant Shares, as applicable, included in
such registration statement for sale in any jurisdiction, the Company will use
its reasonable best efforts promptly to obtain the withdrawal of such order.

If any such registration or comparable statement refers to any holder by name or
otherwise as the holder of any securities of the Company and if, in its sole and
exclusive judgment, such holder is or might be deemed to be a controlling person
of the Company, such holder shall have the right to require (i) the inclusion in
such registration statement of language, in form and substance reasonably
satisfactory to such holder, to the effect that the holding of such securities
by such holder is not to be construed as a recommendation by such holder of the
investment quality of the Company's securities covered thereby and that such
holding does not imply that such holder will assist in meeting any future
financial requirements of the Company, or (ii) in the event that such reference
to such holder by name or otherwise is not required by the Securities Act or any
similar federal statute then in force, the deletion of the reference to such
holder; provided, that with respect to this clause (ii) such holder shall
furnish to the Company an opinion of counsel to such effect, which opinion and
counsel shall be reasonably satisfactory to the Company.

Demand Registrations by the holders of 66-2/3% of the Underlying Common Stock,
of the holders of the shares of Common Stock issued or issuable upon conversion
of the Series C Preferred Stock in connection with two Demand Registrations (in
addition to Demand Registrations requested by the holders of 66-2/3% of the
Underlying Common Stock), any and all registrations on Forms S-2 and S-3 or any
comparable or successor form or forms pursuant to subparagraph 1(c) and any and
all Piggyback Registrations.

     5.   Indemnification.

          (a) Indemnification by the Company. The Company agrees to indemnify to
the extent permitted by law, each holder of Underlying Common Stock and each
holder of Warrant Shares, and each of its respective officers, directors,
employees, partners and agents and each person who controls such holder (within
the meaning of the securities act) against all losses, claims, damages,
liabilities and expenses (including reasonable attorney's fees and expenses and
reasonable costs of investigation and any amounts paid in any settlement
effected with the consent of the Company, which consent shall not be
unreasonably withheld) caused by (i) any untrue or alleged untrue statement of
material fact contained in any registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto, (ii) any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading or (iii) any violation by the
Company of any federal or state law, rule or regulation applicable to the
Company and relating to action required or inaction by the Company in connection
with any such registration, except insofar as the same are caused by or
contained in any information furnished in writing to the Company by such holder
expressly for use therein or by such holder's failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto
after the Company has furnished such holder with a sufficient number of copies
of the same. In connection with an underwritten offering, the Company will
indemnify such underwriters, their officers and directors and each person who
controls such underwriters (within the meaning of the securities act) to the
same extent as provided above with respect to the indemnification of the holders
of Underlying Common Stock and/or Warrant Shares, as applicable.

          (b) Indemnification by Holders. In connection with any registration
statement in which a holder of Underlying Common Stock and/or Warrant Shares, as
applicable, is participating, each such holder will furnish to the Company in
writing such information and affidavits as the Company reasonably requests for
use in connection with any such registration statement or prospectus and, to the
extent permitted by law, will severally but not jointly

<PAGE>

indemnify the Company, its directors and officers and each person who controls
the Company (within the meaning of the securities act) against any losses,
claims, damages, liabilities and expenses resulting from any untrue or alleged
untrue statement of material fact contained in the registration statement,
prospectus or 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 omission is contained in any
information or affidavit so furnished in writing by such holder expressly for
use in any registration statement or prospectus relating to such registration or
should have been contained in any information or affidavit so furnished in
writing by such holder; provided, that the obligation to indemnify will be
individual to each holder and will be limited to the net amount of proceeds
received by such holder from the sale of Underlying Common Stock and/or Warrant
Shares, as applicable, pursuant to such registration statement.

          (c) Notice: Defense of Claims. Any person entitled to indemnification
hereunder will (i) give prompt written notice to the indemnifying party of any
claim with respect to which it seeks indemnification and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party will not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

          (d) Survival: Contribution. The indemnification provided for under
this agreement will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling person of such indemnified party and will survive the
transfer of securities. Subject to the limitations and conditions of this
paragraph 5, the Company also agrees to make such provisions as are reasonably
requested by any indemnified party for contribution to such party in the event
the Company's indemnification provided herein is unavailable for any reason.

     6. Participation in Underwritten Registrations. No Person may participate
in any registration hereunder that is underwritten unless such Person (i) agrees
to sell such Person's securities on the basis provided in any underwriting
arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements, and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements; provided, that no holder of
Underlying Common Stock or Warrant Shares included in any underwritten
registration shall be required to make any representations or warranties to the
Company or the underwriters other than representations and warranties regarding
such holder and such holder's intended method of distribution and a statement to
the effect that nothing has come to the attention of such holder that would lead
such holder to believe that the registration statement or the prospectus
included

<PAGE>

therein contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein in order to make the statements
contained therein, in light of the circumstances under which they were made, not
misleading.

     7.   Miscellaneous.

          (a) No inconsistent agreements. The Company will not hereafter enter
into any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the holders of Underlying Common Stock, Warrants
or Warrant Shares in this Agreement.

          (b) Adjustments Affecting Underlying Common Stock. The Company will
not take any action, or permit any change to occur, with respect to its
securities for the purpose of materially and adversely affecting the ability of
the holders of Underlying Common Stock or Warrants or Warrant Shares to include
such Underlying Common Stock or Warrant Shares in a registration undertaken
pursuant to this Agreement or materially and adversely affecting the
marketability of such Underlying Common Stock or Warrant Shares in any such
registration (including, without limitation, effecting a stock split or a
combination of shares), provided that this subparagraph (b) shall not apply to
actions or changes with respect to the Company's business, earnings or revenues
where the effect of such actions or changes on the Underlying Common Stock and
Warrant Shares is merely incidental.

are inserted for convenience only and do not constitute a part of this
Agreement.

          (j) Governing Law. The construction, validity and interpretation of
this Agreement will be governed by and construed in accordance with the domestic
laws of the State of Texas, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of Texas or any other
jurisdiction) that would cause the application of the laws of any jurisdiction
other than the State of Texas.

          (k) Further Assurances. Each party to this Agreement hereby covenants
and agrees, without the necessity of any further consideration, to execute and
deliver any and all such further documents and take any and all such other
actions as may be necessary or appropriate to carry out the intent and purposes
of this Agreement and to consummate the transactions contemplated hereby.

          (l) Counterparts. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, with the
same effect as if all parties had signed the same document. All such
counterparts shall be deemed an original, shall be construed together and shall
constitute one and the same instrument.

          (m) Reporting. When it is first legally required to do so, the Company
shall register its Common Stock under Section 12 of the Exchange Act and shall
keep effective such registration and timely file such information, documents and
reports as the Commission may require or prescribe under Section 13 of the
Exchange Act. From and after the effective date of the first registration
statement filed by the Company under the Securities Act, the Company shall
(whether or not it shall then be required to do so) timely file such
information, documents and

<PAGE>

reports that a corporation, partnership or other entity subject to Section 13 or
15(d) (whichever is applicable) of the Exchange Act is required to file.
Immediately upon becoming subject to the reporting requirements of either
Section 13 or 15(d) of the Exchange Act, the Company shall promptly upon request
furnish any holder of Underlying Common Stock or Warrant Shares (i) a written
statement by the Company that it has complied with such reporting requirements,
(ii) a copy of the most recent annual or quarterly report of the Company, and
(iii) such other reports and documents filed by the Company with the Commission
as such holder may reasonably request in availing itself of an exemption for the
sale of Underlying Common Stock and Warrant Shares without registration under
the Securities Act. The Company acknowledges and agrees that the purposes of the
requirements contained in this paragraph 7(m) are to enable any such holder to
comply with the current public information requirement contained in paragraph
(c) of Rule 144 under the Securities Act, should such holder ever wish to
dispose of any of the securities of the Company acquired by it without
registration under the Securities Act in reliance upon Rule 144 (or any other
similar exemptive provision), and to qualify the Company for the use of
registration statements on Form S-3. In addition, the Company shall take such
other measures and file such other information, documents and reports, as shall
hereafter be required by the Commission as a condition to the availability of
Rule 144 under the Securities Act (or any similar exemptive provision hereafter
in effect) and the use of Form S-3. The Company also covenants to use its
reasonable best efforts, to the extent that it is reasonably within its power to
do so, to qualify for the use of Form S-3.

          (n) Termination. This Agreement shall terminate on the later to occur
of (i) June 30, 2006 and (ii) the date on which Windward owns less than 1% of
the Common Stock on a fully diluted basis, except that paragraph 5 and paragraph
7(m) shall continue in effect for so long as any shares of Underlying Common
Stock or Warrants or Warrant Shares remain outstanding.

                                    RECITALS:

     The Company and certain of the Security Holders are parties to, among other
agreements, the following agreements (collectively, the "Existing Security

May 10, 1996, as amended by that certain Amendment Agreement dated as of

Agreement dated as of January 1, 1998 (the "Third Amendment Agreement"), and
that certain Transfer, Assignment and Assumption Agreement and Fourth Amendment
Agreement dated as of July 22, 1998 (the "Fourth Amendment Agreement," and

and the Third Amendment Agreement, the "Previous Amendment Agreements") (as so
amended, the "Preferred Subordination Agreement"); (ii) Amended and Restated
