ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
          ------------------------------------------------- 

     The Issuer, CIVC, MIG and certain other investors are parties to a Senior
Subordinated Note, Preferred Stock and Warrant Purchase Agreement, dated
September 30, 1998 (the "Purchase Agreement").  Pursuant to the Purchase
                         ------------------                             
Agreement, CIVC acquired stock purchase warrants (the "Warrants") exercisable
                                                       --------              
into 819,310 shares of Common Stock for an aggregate purchase price of
$68,394.71. CIVC utilized internal funds to consummate the acquisition of the
Warrants. In addition, MIG acquired Warrants exercisable into 204,827 shares of
Common Stock for an aggregate purchase price of $17,098.68. MIG utilized
internal funds and loans from BankAmerica Investment Corporation, an affiliated
corporation, to consummate the acquisition of the Warrants.

     A copy of the Purchase Agreement is attached hereto as Exhibit A and is
incorporated herein by reference.

ITEM 4.   PURPOSE OF TRANSACTION.
          ---------------------- 

     CIVC and MIG acquired the Warrants for investment purposes.  Depending on
market conditions and other factors (including evaluation of the Issuer's
businesses and prospects, availability of funds, alternative uses of funds and
general economic conditions), CIVC and MIG 

                              Page 14 of 25 Pages
<PAGE>
 
may from time to time purchase additional securities of the Issuer or dispose of
all or a portion of their investment in the Issuer.

     Pursuant to the Purchase Agreement, CIVC and MIG each acquired shares of
the Issuer's Series A Preferred Stock, par value $.01 per share (the "Series A
Preferred"). Under the terms of the Series A Preferred, as defined in the
Certificate of Designation, Series A Preferred (the "Certificate of
Designation"), CIVC has the right to designate two members on the Issuer's board
of directors (the "Board"), and if an Event of Noncompliance (as defined in the
Certificate of Designation) has occurred and is continuing, each of the
directors designated by CIVC shall be entitled to cast two votes with respect to
any vote taken by the Issuer's Board. In connection therewith, the Issuer, CIVC,
MIG and certain other stockholders of the Issuer are parties to a Stockholders
Agreement, dated as of September 30, 1998 (the "Stockholders Agreement")
pursuant to which each party has agreed to (i) vote all of their shares in favor
of those members of the Board designated by CIVC and (ii) vote all of their
shares in favor of removing an existing director on the Board and filling the
vacancy with a member designated by CIVC in the event that the directors
designated by CIVC are not entitled to cast two votes after the occurrence and
during the continuance of an Event of Noncompliance. In addition, pursuant to
the terms of the Stockholders Agreement, each party thereto has agreed to vote
all of its shares in favor of a Sale of the Company (as defined in the
Shareholders Agreement) proposed by CIVC. As of the date of this statement,
stockholders holding an aggregate of 1,132,825 shares of Common Stock were
parties to the Stockholders Agreement. CIVC expressly disclaims beneficial
ownership of all of the shares of Common Stock owned by the other parties to the
Shareholders Agreement. A copy of the Certificate of Designation is attached
hereto as Exhibit B and is incorporated herein by reference, and a copy of the
Stockholders Agreement is attached hereto as Exhibit C and is incorporated
herein by reference.

     Pursuant to a Registration Agreement, dated as of September 30, 1998 (the
"Registration Agreement"), by and among the Issuer, CIVC, MIG and certain other
stockholders of the Issuer, CIVC, MIG and such other stockholders were granted
certain registration rights with respect to their Warrants and the underlying
Common Stock. A copy of the Registration Agreement is attached hereto as Exhibit
D and is incorporated herein by reference.

     The summaries of the agreements referred to in this Item 4 and elsewhere in
this Statement are not intended to be complete and are qualified in their

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER.

     CIVC is the direct beneficial owner of Warrants currently exercisable into
819,310 shares of Common Stock and MIG is the direct beneficial owner of
Warrants currently exercisable into 204,827 shares of Common Stock. CIVC and MIG
may be deemed to constitute a "group" for purposes of Section 13(d)(3) of the
Exchange Act, and therefore each may be deemed to own beneficially warrants
currently exercisable into 1,024,137 shares of Common Stock, which, when
exercised would result in ownership of approximately 35.6% of the Issuer's
Common Stock as computed under Rule 13d-3.

                              Page 15 of 25 Pages

<PAGE>
 
This filing shall not be deemed an admission that CIVC, on the one hand, or MIG,
on the other, is, for purposes of Section 13(d) and 13(g) of the Exchange Act, 
the beneficial owner of any securities covered in this Statement as held by the 
other. By virtue of the relationship between BA Bank and CIVC described in Item
2, BA Bank may be deemed to possess indirect beneficial ownership of the shares
of Common Stock beneficially owned by CIVC, and by virtue of the relationship
between BAC and BA Bank described in Item 2, BAC may be deemed to possess
indirect beneficial ownership of the shares of Common Stock beneficially owned
by CIVC. By virtue of their relationship as general partners of MIG, each
General Partner may be deemed to possess indirect beneficial ownership of the
Common Stock beneficially owned by MIG. The filing of this Statement by BA Bank,
BAC and the General Partners shall not be deemed an admission that any of BA
Bank, BAC or the General Partners is, for purposes of Section 13(d) or 13(g) of
the Exchange Act, the beneficial owner of any of the securities covered by this
Statement.

     The percentages of Common Stock calculated in this Item 5 are based upon
1,854,692 shares of Common Stock issued and outstanding as of July 31, 1998, as
disclosed in the Issuer's Form 10-Q filed with the Commission on July 31, 1998
for the fiscal quarter ended June 30, 1998.

     Within the last 60 days, none of the Reporting Persons has been involved in
any transactions involving the Common Stock other than as described above.

     No person other than the Reporting Persons has the right to receive or the
power to direct the receipt of dividends from the proceeds from the sale of the
Shares.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          ---------------------------------------------------------------------
          TO SECURITIES OF THE ISSUER.
          --------------------------- 

          Except as set forth in Item 4, to the best knowledge of the Reporting
Persons, no contracts, arrangements, understandings or relationships (legal or
otherwise) exist among the persons named in Item 2 or between such persons and
any other person with respect to any securities of the Issuer, including but not
limited to transfer or voting of any such securities, finder's fees, joint
venture, loan or option arrangements, puts or calls, guarantees of profits,
divisions of profits or losses, or giving or withholding of proxies.

     is relinquished by the SBIC Holder) and (iv) amend this

   ---------             -----------  --  --     -- 
such Indemnified Liability, together will all other such Indemnified
Liabilities, exceeds $250,0000, in which case such Indemnitee shall be entitled
to indemnification only for the amount of such excess; it being understood,
however, that the foregoing limitation applies only to Indemnified Liabilities
arising out of breaches of representations and warranties contained in Section 6
                                                                       ---------

certificate, instrument or other documents contemplated by this Agreement to the
contrary notwithstanding, the obligations of the Company under this Agreement
and the Notes will be subject to the limitation that payments of interest will

provisions of law applicable to the Noteholder in question limiting rates of
interest which may be charged or collected by such Noteholder.

          11E. Consent to Amendments.  Except as otherwise expressly provided
               ---------------------                                         
herein, commencing on and after the Closing the provisions of this Agreement may
be amended or waived, and the Company may take any action herein prohibited, or
omit to perform any act herein required to be performed by it, only if such
Person has obtained the written consent of the Majority Holders; provided that

                                           ---------

only if the Company has obtained the written consent of the Majority Warrant
Holders and only if the provisions of all Warrants are amended in the same
manner and (z) any provision of this Agreement which would continue to apply
after the Notes and Series A Preferred are paid in full may be amended if and
only if the Company has obtained the written consent of the Majority Warrant
Holders.  No other course of dealing between the Company and any Securityholder
or any delay in exercising any rights hereunder, under any of the Securities,
under any other agreement contemplated hereby or the Company's Articles of
Incorporation shall operate as a waiver of any rights of any such holders.  For
purposes of this Agreement, the Notes and Warrant Stock held by the Company or
any of its Subsidiaries shall not be deemed to be outstanding or in existence.
If the Company directly or indirectly pays any consideration to any
Securityholder for such holder's consent to any amendment, modification or
waiver hereunder, the Company shall also pay each other holder of the same type
of Securities granting its consent hereunder equivalent consideration computed
on a pro rata basis.

whether or not any express assignment has been made, the provisions of this
Agreement which are for the benefit of the Purchasers as purchasers or
Securityholders are also for the benefit of, and enforceable by, any subsequent
Securityholder.

          11G. Severability.  Whenever possible, each provision of this

Agreement shall be interpreted in such manner as to be effective and valid under
applicable Laws, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable Laws, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          11H. Counterparts.  This Agreement may be executed in two or more
               ------------                                                
counterparts, any one of which need not contain the signatures of more than one
party, but all such counterparts taken together shall constitute one and the

illustrative only and will not be interpreted as a limitation on, or an
exclusive listing.  The "knowledge" or "awareness" of a Person means the actual

ANY NOTE WARRANT, ANY SERIES A WARRANT, THE WARRANT STOCK, THE STOCKHOLDERS

purposes as a reduction in the issue price of the debt issued to the Purchasers,

Board of Directors and to the extent permitted under the Texas Business
Corporation Act and other applicable law, the Corporation shall pay preferential
dividends in cash to the holders of the Series A Preferred Stock as provided in
this Section 2.  Dividends on each share of the Series A Preferred Stock (a
     ---------                                                             
"Series A Preferred Share") shall accrue on a daily basis at the rate of 8.0%
- -------------------------                                                    
per annum of the sum of $100.00 (the "Liquidation Value") plus all accumulated

and unpaid dividends thereon from and including the date of issuance of such
Series A Preferred Share to and including the first to occur of (i) the date on
which the Liquidation Value of such Series A Preferred Share (plus all accrued
and unpaid dividends thereon) is paid to the holder thereof in connection with
the liquidation of the Corporation or the redemption of such Series A Preferred
Share by the Corporation or (ii) the date on which such share is otherwise
acquired by the Corporation.  Such dividends shall accrue whether or not they
have been declared and whether or not there are profits, surplus or other funds
of the Corporation legally available for the payment of dividends (other than
dividends on capital stock of the Corporation paid with shares of stock of the
same class), and such dividends shall be cumulative such that all accrued and
unpaid dividends shall be fully paid or declared with funds irrevocably set

payments may be made with respect to the Common Stock, the Series B Preferred
Stock, the Series C 
<PAGE>
 
Preferred or any capital stock or other equity securities of the Corporation
(collectively, the "Junior Securities"). The date on which the Corporation
                    -----------------                          
initially issues any Series A Preferred Share shall be deemed to be its "date of
issuance" regardless of the number of times transfer of such Series A Preferred
Share is made on the stock records maintained by or for the Corporation and
regardless of the number of certificates which may be issued to evidence such
Series A Preferred Share.

          (b) Dividend Reference Dates.  To the extent not paid on March 15,
              ------------------------                                      
June 15, September 15, and December 15 of each year, beginning December 31, 1998
(the "Dividend Reference Dates"), all dividends which have accrued on each
      ------------------------                                            
Series A Preferred Share outstanding during the three-month period (or other
period in the case of the initial Dividend Reference Date) ending upon each such
Dividend Reference Date shall be accumulated and shall remain accumulated
dividends with respect to such Series A Preferred Share until paid to the holder
thereof.

          (c) Distribution of Partial Dividend Payments.  Except as otherwise
              -----------------------------------------                      
provided herein, if at any time the Corporation pays less than the total amount
of dividends then accrued with respect to the Series A Preferred Stock, such
payment shall be distributed pro rata among the holders thereof based upon the
aggregate accrued but unpaid dividends on the Series A Preferred Shares held by
each such holder.

          3.  Liquidation.  Upon any liquidation, dissolution or winding up of
              -----------                                                     
the Corporation (whether voluntary or involuntary), each holder of Series A
Preferred Stock shall be entitled to be paid, before any distribution or payment
is made upon any Junior Securities, an amount in cash equal to the aggregate
Liquidation Value of all Series A Preferred Shares held by such holder (plus all
accrued and unpaid dividends thereon), and the holders of Series A Preferred
Stock shall not be entitled to any further payment.  If upon any such
liquidation, dissolution or winding up of the Corporation the Corporation's
assets to be distributed among the holders of the Series A Preferred Stock are
insufficient to permit payment to such holders of the aggregate amount which
they are entitled to be paid under this Section 3, then the entire assets
                                        ---------                        
available to be distributed to the Corporation's stockholders shall be
distributed pro rata among such holders based upon the aggregate Liquidation
Value (plus all accrued and unpaid dividends) of the Series A Preferred Stock
held by each such holder.  Prior to the liquidation, dissolution or winding up
of the Corporation, the Corporation shall declare for payment all accrued and
unpaid dividends with respect to the Series A Preferred Stock, but only to the
extent of funds of the Corporation legally available for the payment of
dividends.  Not more than 60 nor less than 30 days prior to the payment date
stated therein, the Corporation shall mail written notice of any such
liquidation, dissolution or winding up to each record holder of Series A
Preferred Stock, setting forth in reasonable detail the amount of proceeds to be
paid with respect to each share of capital stock of the Corporation, including
each Series A Preferred Share, each share of Series B Preferred Stock, each
share of Series C Preferred Stock and each share of Common Stock in connection
with such liquidation, dissolution or winding up.

          4.  Priority on Dividends and Redemptions.  So long as any Series A
              -------------------------------------                          
Preferred Stock remains outstanding, without the prior written consent of the
holders of a majority of the

outstanding shares of Series A Preferred Stock, the Corporation shall not, nor
shall it permit any Subsidiary to, redeem, purchase or otherwise acquire
directly or indirectly any Junior Securities, nor shall the Corporation directly
or indirectly pay or declare any dividend or make any distribution upon any
Junior Securities, other than (i) repurchases of Common Stock from any employee
of the Corporation provided that (A) no Default or Event of Default (as defined
in the Senior Subordinated Note, Preferred Stock and Warrant Purchase Agreement,

immediately after such repurchase or payment, (B) the purchase price paid in
such repurchase or the amount of such payment does not exceed the fair market
value of the stock repurchased or is in an amount calculated pursuant to the
terms of a repurchase or employment agreement between the Corporation and such
employee entered into in connection with the commencement of such employee's
employment, (C) such purchase occurs after September 30, 1999 and (D) the
aggregate amount paid or payable in any fiscal year in respect of all such
purchases from employees does not exceed $250,000, (ii) dividends paid in
accordance with the terms of the Series B Preferred and the terms of the Series
C Preferred; provided that no Default or Event of Default (as defined in the
Purchase Agreement) or an Event of Noncompliance is in existence immediately
prior to or immediately after such dividend and (iii) dividends on capital stock
of the Corporation paid with shares of stock of the same class.

without cost to such holder within five business days after surrender of the
certificate representing the redeemed Series A Preferred Shares.

          (b)  Consequences of Certain Events of Noncompliance.
               ----------------------------------------------- 

          i.   If an Event of Noncompliance has occurred, the dividend rate per
annum on the Series A Preferred Stock shall increase immediately by an increment
of 3.0 percentage points i.e. the dividend rate will increase from 8.0% to 11.0%
per annum.  If such Event of Noncompliance remains uncured for a period of 180
days, the dividend rate per annum on the Series A Preferred Stock shall increase
at the end of such 180 day period from 11.0% to 13.0%.  Any increase of the
dividend rate resulting from the operation of this paragraph shall terminate as
of the close of business on the date on which no Event of Noncompliance exists,
subject to subsequent increases pursuant to this paragraph.

          ii.  If an Event of Noncompliance has occurred, the holder or holders
of a majority of the Series A Preferred Stock then outstanding may demand (by
written notice delivered to the Corporation) immediate redemption of all or any
portion of the Series A Preferred Stock owned by such holder or holders at a
price per Series A Preferred Share equal to the Liquidation Value thereof (plus
all accrued and unpaid dividends thereon).  The Corporation shall give prompt
written notice of such election to the other holders of Series A Preferred Stock
(but in any event within five days after receipt of the initial demand for
redemption), and each such other holder may demand immediate redemption of all
or any portion of such holder's Series A Preferred Stock by giving written
notice thereof to the Corporation within seven days after receipt of the
Corporation's notice.  The Corporation shall redeem all Series A Preferred Stock
as to which rights under this paragraph have been exercised within 15 days after
receipt of the initial demand for redemption.

          iii. If any Event of Noncompliance has occurred each Series A Director
shall automatically be entitled to cast two votes with respect to any matter
submitted to a vote of the board of directors.  Each Series A Director may
exercise its right to cast two votes in accordance with the preceding sentence
with respect to any matter, including any matter at any annual or other special
meeting of directors, and to the extent and in the manner permitted by
applicable law, pursuant to a written consent in lieu of a meeting of the board
of directors. Such special right shall continue until such time as there is no
longer any Event of Noncompliance in existence, at which time such special right
shall terminate subject to revesting upon the occurrence and continuation of any
Event of Noncompliance which gives rise to such special right hereunder.

          iv.  If any Event of Noncompliance exists, each holder of Series A
Preferred Stock shall also have any other rights which such holder is entitled
to under any contract or agreement at any time and any other rights which such
holder may have pursuant to applicable law.

          8.   Registration of Transfer.  The Corporation shall keep at its
               ------------------------                                    
principal office a register for the registration of Series A Preferred Stock.
Upon the surrender of any certificate 

                                      -9-
<PAGE>
 
representing Series A Preferred Stock at such place, the Corporation shall, at
the request of the record holder of such certificate, execute and deliver (at
the Corporation's expense) a new certificate or certificates in exchange
therefor representing in the aggregate the number of Series A Preferred Shares
represented by the surrendered certificate. Each such new certificate shall be
registered in such name and shall represent such number of Series A Preferred
Shares as is requested by the holder of the surrendered certificate and shall be
substantially identical in form to the surrendered certificate, and dividends
shall accrue on the Series A Preferred Stock represented by such new certificate
from the date to which dividends have been fully paid on such Series A Preferred
Stock represented by the surrendered certificate.

          9.   Replacement.  Upon receipt of evidence reasonably satisfactory to
               -----------                                                      
the Corporation (an affidavit of the registered holder shall be satisfactory) of
the ownership and the loss, theft, destruction or mutilation of any certificate
evidencing shares of Series A Preferred Stock, and in the case of any such loss,
theft or destruction, upon receipt of indemnity reasonably satisfactory to the
Corporation (provided that if the holder is a financial institution or other
institutional investor or a Purchaser as defined in the Purchase Agreement, its
own agreement shall be satisfactory), or, in the case of any such mutilation
upon surrender of such certificate, the Corporation shall (at its expense)
execute and deliver in lieu of such certificate a new certificate of like kind
representing the number of Series A Preferred Shares of such class represented
by such lost, stolen, destroyed or mutilated certificate and dated the date of
such lost, stolen, destroyed or mutilated certificate, and dividends shall
accrue on the Series A Preferred Stock represented by such new certificate from
the date to which dividends have been fully paid on such lost, stolen, destroyed
or mutilated certificate.

          10.  Amendment and Waiver. No amendment, modification or waiver shall
               --------------------                                       
be binding or effective with respect to any provision hereof, without the prior
written consent of the holders of a majority of the Series A Preferred Stock
outstanding at the time such action is taken.

          11.  Notices. Except as otherwise expressly provided hereunder, all
               -------

          4.   Restrictions on Transfer of Stockholder Shares.
               ---------------------------------------------- 

          (a)  Transfer of Stockholder Shares. No Executive or Other Stockholder
               ------------------------------  
shall sell, transfer, assign, pledge or otherwise dispose of (whether with or
without consideration and whether voluntarily or involuntarily or by operation
of law) any interest in his or its Stockholder Shares (a "Transfer"), except
                                                          --------          
pursuant to the provisions of Section 6, in connection with a Public Sale,
pursuant to the Stock Purchase Option Agreements (as defined in the Purchase
Agreement) or with the prior written approval of the Majority Investor Holders
or, in the case of the Executives, pursuant to the provisions of this Section 4.

          (b)  Tag-Along Rights.  At least thirty 30 days prior to any Transfer
               ----------------                                                
of Stockholder Shares (other than a Public Sale), the Executive making such
Transfer (the "Transferring Stockholder") shall deliver a written notice (the
               ------------------------                                      
"Sale Notice") to the holders of Investor Shares, specifying in reasonable
- ------------                                                              
detail the identity of the prospective transferee(s), the number of shares to be
transferred and the terms and conditions of the contemplated Transfer.  Each
holder of Investor Shares may elect to participate in the contemplated Transfer
at the same price per share (whether voting or non-voting stock) and on the same
terms by delivering written notice to the Transferring Stockholder within 30
days after delivery of the Sale Notice.  If any holder of Investor 

                                      -4-
<PAGE>
 
Shares has elected to participate in such contemplated Transfer, the
Transferring Stockholder and each such electing holder shall be entitled to sell
in the contemplated Transfer, at the same price and on the same terms, a number
of Stockholder Shares equal to the product of (i) the quotient determined by
dividing the percentage of Stockholder Shares owned by such Person by the
aggregate percentage of Stockholder Shares owned by the Transferring Stockholder
and the holders of Investor Shares participating in such sale and (ii) the
number of Stockholder Shares to be sold in the contemplated Transfer.

          Each Executive shall use its best efforts to obtain the agreement of
the prospective transferee(s) to the participation of the holders of Investor
Shares in any contemplated Transfer and to the inclusion of the Investor
Warrants and Series A Preferred in the contemplated Transfer, and no Executive
shall transfer any of its Stockholder Shares to any prospective transferee if
such prospective transferee(s) declines to allow the participation of the
holders of Investor Shares or the inclusion of the Warrants or Series A
Preferred.  If any portion of the Investor Warrants is included in any Transfer
of Stockholder Shares under this Section 4(b), the purchase price for the
Investor Warrants shall be equal to the full purchase price determined hereunder
for the Stockholder Shares covered by the portion of the Investor Warrants to be
transferred, reduced by the aggregate exercise price for such shares.

          (c)  Permitted Transfers.  The restrictions set forth in this Section
               -------------------
4 shall not apply with respect to any Transfer of Stockholder Shares by any
Executive pursuant to applicable laws of descent and distribution or among such
Executive's Family Group (collectively referred to herein as "Permitted

continue to be applicable to the Stockholder Shares after any such Transfer and

will exist an Event of Default (as defined in each of the Purchase Agreement and
the Loan Agreement) and the Company shall have used its best efforts to obtain
financing from an outside source for payment of the Put Price, then the Company
may pay the Put Price by delivery (i) of cash (as provided above) up to the
maximum portion of the Put Price, the payment of which will not result in the
occurrence or existence of an Event of Default and (ii) a promissory note in a
principal amount equal to that portion of the Put Price not being paid pursuant
to the foregoing clause (i), payable in three successive annual installments,
with the first installment due on the first anniversary of the delivery of the

Price shall be reduced by the aggregate exercise price of such portion of the
Warrants.

                    ---------

of, plus accrued and unpaid interest on, outstanding indebtedness as of such
date minus the liquidation value of, plus accrued and unpaid dividends, if any,

shall be equal to the amount which such holder would receive with respect to the
Investor Shares specified by such holder in such holder's Put Notice in the
event of a Sale of the Company for an aggregate purchase price equal to the
value attributable to the Company in accordance with the foregoing sentence.

          In calculating the Put Price, all accounting determinations shall be
made in accordance with generally accepted accounting principles consistently
applied.

          (e)  The Investors' right to exercise the Put hereunder shall
terminate upon the first to occur of (i) the 10th anniversary of the date of

          1.   Demand Registrations.
               -------------------- 

          (a)  Requests for Registration.  At any time after the date hereof the
               -------------------------

                                                                   --------

Securities on Form S-1 or any similar long-form registration ("Long-Form

- -------------                                                               
("Short-Form Registrations") if available. All registrations requested pursuant
  ------------------------                                                      
to this paragraph l(a) are referred to herein as "Demand Registrations."  Each
                                                  --------------------        
request for a Demand Registration shall specify the approximate number of
Registrable Securities requested to be registered, the anticipated per share
price range for such offering and the intended method of disposition. Within ten
(10) days after receipt of any such request, the Company shall give written
notice of such requested registration to all other holders of Registrable
Securities and shall include in such registration all Registrable Securities
with respect to which the Company has received written requests for inclusion
therein within 15 days after the receipt of the Company's notice.

          (b)  Long-Form Registrations.  The Majority Investor Holders shall be
               -----------------------                                         
entitled to request two (2) Long-Form Registrations in which the Company shall
pay all Registration 
<PAGE>
 
Expenses (as defined in Section 6(a)) associated with the public offering of the
                        ------------                     
Company's equity securities Investor Holders. A registration shall not count as
one of the permitted Long-Form Registrations until it has become effective and
neither the last nor any subsequent Long-Form Registration shall count as one of
the permitted Long-Form Registrations unless the holders of Registrable
Securities are able to register and sell all of the Registrable Securities
requested to be included in such registration; provided that in any event the
Company shall pay all Registration Expenses in connection with any registration
initiated as a Long-Form Registration whether or not it has become effective and
whether or not such registration has counted as one of the Long-Form
Registrations.

          (c)  Short-Form Registrations.  In addition to the Long-Form
               ------------------------                               
Registrations provided pursuant to Section l(b), the Majority Investor Holders
                                   ------------                               
shall be entitled to request five (5) Short-Form Registrations in which the
Company shall pay all Registration Expenses; provided that in each such Short-
Form Registration the holders of Registrable Securities shall request to include
in such registration at least 25% of the Registrable Securities held by them in
the aggregate as of the date hereof (or such lesser amount if less than 25% are
unregistered as of such demand). Demand Registrations shall be Short-Form
Registrations whenever the Company is permitted to use any applicable short
form.

          (d)  Restrictions on Demand Registrations.  The Company shall not be
               ------------------------------------                           
obligated to effect any Demand Registration within 180 days after the effective
date of a previous Demand Registration or a previous registration in which the
holders of Registrable Securities were given piggyback rights pursuant to
Section 2 and in which there was no reduction in the number of Registrable
- ---------                                                                 
Securities requested to be included. The Company may postpone for up to 180 days
(from the date of the request) the filing or the effectiveness of a registration
statement for a Demand Registration if the Company's board of directors
determines in its reasonable good faith judgment that such Demand Registration
would reasonably be expected to have a material adverse effect on any proposal
or plan by the Company or any of its Subsidiaries to engage in any acquisition
of assets (other than in the ordinary course of business) or any merger,
consolidation, tender offer, reorganization or similar transaction; provided
that in such event, the holders of Registrable Securities initially requesting
such Demand Registration shall be entitled to withdraw such request and, if such
request is withdrawn, such Demand Registration shall not count as one of the
permitted Demand Registrations hereunder and the Company shall pay all
Registration Expenses in connection with such registration. The Company may
delay a Demand Registration hereunder only once in any twelve-month period.

          (e)  Selection of Underwriters.  In any Demand Registration, the
               -------------------------                                  
Company shall have the right to select the investment banker(s) and manager(s)
to administer the offering, provided that the investment banker(s) and
manager(s) so selected are reasonably satisfactory to the Majority Investor
Holders.

          2.   Piggyback Registrations.
               ----------------------- 

          (a)  Right to Piggyback.  Whenever the Company proposes to register 
               ------------------                                             
any of its securities under the Securities Act (other than pursuant to (i) a
Demand Registration or (ii) pursuant to a registration on Form S-4 or S-8 or any
successor or similar forms) and the registration form to be used may be used for
the registration of Registrable Securities (a "Piggyback Registration"), the
                                               ----------------------       
Company shall give prompt written notice (in any event within ten (10) days
after its receipt of notice of any exercise of demand registration rights other
than under this Agreement) to all holders of Registrable Securities of its
intention to effect such a registration and shall include in such registration
all Registrable Securities with respect to which the Company has received
written requests for inclusion therein within 15 days after the receipt of the
Company's notice.

          (b)  Piggyback Expenses.  The Registration Expenses of the holders of
               ------------------                                              
Registrable Securities shall be paid by the Company in all Piggyback
Registrations.

          (c)  Priority on Piggyback Registrations.  If a Piggyback Registration
               -----------------------------------                              
is an underwritten primary registration on behalf of 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 which can be sold in such offering without adversely affecting the
marketability of the offering, the Company shall include in such registration
(i) first, the securities the Company proposes to sell, and (ii) second, the
    -----                                                        ------     
Registrable Securities requested to be included in such registration pro rata
among the holders thereof on the basis of the number of shares of Registrable
Securities owned by each such holder, and (iii) third, other securities
                                                -----                  
requested to be included in such registration pro rata among the holders of such
securities and any other securities held by others requested to be included in
such registration, pro rata among the holders thereof on the basis of the number
of shares requested to be included in such registration.

          (d)  Priority on Secondary Registrations.  If a Piggyback Registration
               -----------------------------------                              
is an underwritten secondary registration on behalf of holders of the Company's
securities (other than the parties hereto) who have been granted contractual
demand registration rights, 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 such offering
without adversely affecting the marketability of the offering, the Company will
include in such registration (i) first, the securities requested to be included
                                 -----                                         
therein by the holders requesting such registration, pro rata among the holders

          4.   Registration Procedures.  Whenever the holders of Registrable
               -----------------------                                      
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company shall use its best efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof (including the registration of the
Warrants held by a holder of Registrable Securities requesting registration as
to which the Company has received reasonable assurances that only Common Stock
shall be distributed to the public), and pursuant thereto the Company shall as
expeditiously as possible:

          (a)  prepare and file with the Securities and Exchange Commission a
registration statement with respect to such Registrable Securities 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 shall furnish to the counsel selected by the
holders of a majority of the Registrable Securities covered by such registration
statement copies of all such documents proposed to be filed, which documents
shall be subject to the review and comment of such counsel);

          (b)  notify each holder of Registrable Securities of the effectiveness
of each registration statement filed hereunder and prepare and file with the
Securities and Exchange 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 not less
than 180 days 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 disposition by the
sellers thereof set forth in such registration statement;

                                      -4-
<PAGE>
 
          (c)  furnish to each seller of Registrable Securities such number of
requested 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 Registrable Securities
owned by such seller;

          (d)  use its reasonable best efforts to register or qualify such
Registrable Securities 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 Registrable
Securities owned by such seller (provided that the Company shall not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subparagraph, (ii) subject itself
to taxation in any such jurisdiction or (iii) consent to general service of
process in any such jurisdiction);

          (e) notify each seller of such Registrable Securities, 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 shall
prepare a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not contain an untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading; provided that upon
such notification by the Company, each seller of such Registrable Securities
will not offer or sell such Registrable Securities until the Company has
notified such seller that it has prepared a supplement or amendment to such
prospectus and delivered copies of such supplement or amendment to such seller;

          (f)  cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on the NASD automated quotation
system and, if listed on the NASD automated quotation system, use its best
efforts to secure designation of all such Registrable Securities covered by such
registration statement as a NASDAQ "national market system security" within the
meaning of Rule 11Aa2-1 of the Securities and Exchange Commission or, failing
that, to secure NASDAQ authorization for such Registrable Securities and,
without limiting the generality of the foregoing, to arrange for at least two
market makers to register as such with respect to such Registrable Securities
with the NASD;

          (g)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)  enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate 

                                      -5-
<PAGE>
 
the disposition of such Registrable Securities (including effecting a stock
split or a combination of shares);

          (i)  make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter (in each case after reasonable prior notice), 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, on a confidential basis, all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in
connection with such registration statement;

          (j)  otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange 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;

          (k)  permit any holder of Registrable Securities which holder, in its
sole and exclusive judgment, might be deemed 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;

          (l)  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 common stock included in such registration statement for sale in any
jurisdiction, the Company shall use its best efforts promptly to obtain the
withdrawal of such order; and

          (m)  obtain a comfort letter from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by comfort letters as the holders of a majority of the Registrable
Securities being sold reasonably request (provided that such Registrable
Securities constitute at least 10% of the securities covered by such
registration statement).

Each seller of Registrable Securities, upon receipt of any notice from the
Company of the happening of any event of the kind described in subsection (e) of
this Section 4, will forthwith discontinue disposition of the Registrable
Securities until receipt by the seller of Registrable Securities of the copies
of the supplemented or amended prospectus contemplated by subsection (e) of this
Section 4 or until it is advised in writing (the "Advice") by the Company that
the use of the prospectus may be resumed and has received copies of any
additional or supplemental filings which are incorporated by reference in the
prospectus, and if so directed by the Company, such seller of Registrable
Securities will, or will request the managing underwriter or underwriters, if
any, to deliver to the Company (at the Company's expense) all copies (other than
permanent file copies)

                                      -6-
<PAGE>
 
then in the possession of such seller of Registrable Securities and of any
underwriter or underwriters, of he prospectus covering such Registrable
Securities current at the time of receipt of such notice. In the event the
Company shall give any such notice, the time periods mentioned in subsection (b)
of this Section 4 shall be extended by the number of days during the period from
and including the date of the giving of such notice to and including the date
when each seller of Registrable Securities covered by such registration
statement shall have received the copies of the supplemented or amended
prospectus contemplated by subsection (e) of this Section 4 hereof or the
Advice.

          5.   Cooperation by Holders of Registrable Securities
               ------------------------------------------------

          (a)  Each seller of Registrable Securities will furnish to the Company
in writing such information as the Company may reasonably require from time to
time from such seller, and otherwise reasonably cooperate with the Company in
connection with any registration with respect to such holder's Registrable
Securities.

          (b)  The failure of any prospective seller of Registrable Securities
to furnish any information or documents in accordance with any provision
contained in this Agreement shall not affect the obligations of the Company
hereunder to any remaining sellers who furnish such information and documents
unless, in the reasonable opinion of counsel to the Company or the underwriters,
such failure impairs or may impair the viability of the or the legality of any
registration statement in connection therewith.

          (c)  At the end of any period during which the Company is obligated to
keep any registration statement current and effective as provided in Section 4,
                                                                     --------- 
the holders of Registrable Securities included in such registration statement
shall discontinue sales of shares pursuant to such registration statement upon
receipt of notice from the Company of its intention to remove from registration
the shares covered by such registration statement which remain unsold and such
holders shall notify the Company of the number of shares registered which remain
unsold promptly after receipt of such notice from the Company.

          6.   Registration Expenses.
               ----------------------

          (a)  All expenses incident to the Company's performance of or
compliance with this Agreement, including without limitation all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, fees and disbursements
of custodians, and fees and disbursements of counsel for the Company and all
independent certified public accountants, underwriters (excluding discounts,
commissions, and undocumented expense allowances) and other Persons (as defined
in the Purchase Agreement) retained by the Company (all such expenses being
herein called "Registration Expenses"), shall be borne as provided in this
               ---------------------                                      
Agreement, except that the Company shall, in any event, pay its internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit or quarterly review, the expense of any liability insurance and
the expenses and fees for listing the securities to be registered on each
securities exchange on which similar securities issued by the Company are then
listed or on the NASD automated quotation system.

                                      -7-
<PAGE>
 
          (b)  In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Investor Registrable
Securities included in such registration for the reasonable fees and
disbursements of one counsel chosen by the holders of a majority of the Investor
Registrable Securities initially requesting such registration.  The Company
shall not be required to pay or obtain reimbursement for excessive discounted
fees and commissions attributable to a sale of the Company and fees and/or
expenses of other experts retained by the holders of Registrable Securities.

          (c)  To the extent Registration Expenses are not required to be paid
by the Company, each holder of securities included in any registration hereunder
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
shall be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.

          (d)  The Company will not bear the cost of or pay for any stock
transfer tax imposed in respect of the transfer of any Registrable Securities to
any purchaser thereof by any holder of Registrable Securities in connection with
any registration of Registrable Securities pursuant to this Agreement.

          7.   Indemnification.
               --------------- 

          (a)  The Company agrees to indemnify, to the extent permitted by law,
each holder of Registrable Securities (requesting or joining in a registration
hereunder), its officers and directors and each Person who controls (within the
meaning of the Securities Act) such holder against all losses, claims, damages,
liabilities and expenses caused by 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 or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, 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 shall 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 Registrable Securities.

          (b)  In connection with any registration statement in which a holder
of Registrable Securities is participating, each such holder shall 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, shall indemnify the Company, its
directors and officers and each Person who controls (within the meaning of the
Securities Act) the Company 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

                                      -8-
<PAGE>
 
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; provided that the obligation to indemnify shall be
limited to the net amount of proceeds received by such holder from the sale of
Registrable Securities pursuant to such registration statement. In connection
with an underwritten offering in which a holder of Registrable Securities is
participating, each such holder shall 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 Company.

          (c)  Any Person entitled to indemnification hereunder shall (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice
shall not impair any Person's right to indemnification hereunder to the extent
such failure has not prejudiced the indemnifying party) 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 shall not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent shall not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim shall 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)  The indemnification provided for under this Agreement shall
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 shall survive the transfer of securities. The
parties hereto also agree to make such provisions, as are reasonably requested
by any indemnified party, for contribution to such party in the event such
party's indemnification is unavailable for any reason.

          8.   Participation in Underwritten Registrations.  No Person may
               -------------------------------------------                
participate in any registration hereunder which 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 Registrable Securities 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) or to undertake any
indemnification obligations to the Company or the underwriters with respect
thereto, except as otherwise provided in Section 7 hereof.

market maker in compliance with Rule 144 under the Securities Act (or any
similar rule then in force) or repurchased by the Company or any Subsidiary. For
purposes of this Agreement, a Person shall be deemed to be a holder of Investor
Registrable Securities, and the Registrable Securities shall be deemed to be in

Registrable Securities when they have been distributed to the public pursuant to
a offering registered under the Securities Act or sold to the public through a
broker, dealer or market maker in compliance with Rule 144 under the Securities
Act (or any similar rule then in force) or repurchased by the Company or any
Subsidiary. For purposes of this Agreement, a Person shall be deemed to be a
holder of Other Registrable Securities, and the Other Registrable Securities
shall be deemed to be in existence, whenever such Person has the right to
acquire directly or indirectly such Other Registrable Securities (upon
conversion or exercise in connection with a transfer of securities or otherwise,
but disregarding any restrictions or limitations upon the exercise of such
night), whether or not such acquisition has actually been effected, and such
Person shall be entitled to exercise the rights of a holder of Other Registrable
Securities hereunder.

illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
the validity, legality or enforceability of any other provision of this
Agreement in such jurisdiction or affect the validity, legality or

party, but all such counterparts taken together shall constitute one and the
same Agreement.

          (g)  Remedies.  Any Person having rights under any provision of this
               --------
