COVENANTS. Grantor hereby expressly covenants and agrees with Trustee and
Beneficiary that:

(1)      PERFORMANCE OF OBLIGATIONS. Grantor will duly perform all of its
         obligations under this Deed of Trust in accordance with the terms
         hereof.

(2)      DUE ON SALE OR ENCUMBRANCE. Grantor will not, without the prior written
         consent of Beneficiary, transfer, convey or otherwise part with title
         to any of the Mortgaged Property, or any portion thereof or ownership
         interest therein, or create or permit or allow to exist or to be
         created any mortgage, deed of trust, pledge or other lien or
         encumbrance on any of the Mortgaged Property, other than this Deed of
         Trust, and Grantor will not suffer or permit any mechanic's or
         materialmen's lien or any other lien of any nature whatsoever to attach
         to any of the Mortgaged Property or to remain outstanding against the
         same or any part thereof; provided, however, Grantor shall not be in
         default under this Deed of Trust as a result of the filing of any
         mechanic's or materialmen's liens against or otherwise encumbering any
         of the Mortgaged Property arising out of the construction by or for the
         benefit of Grantor of the Building to the extent of any such
         construction completed as of the date of this Deed of Trust; provided,
         however, Grantor shall pay the amounts resulting in such liens or
         otherwise bond over such liens to the extent necessary to prevent the
         foreclosure of any such liens. Beneficiary hereby consents to
         arrangements between Grantor and a third party providing for (i) the
         installation in the Building of communications and/or computer
         equipment owned or leased by third parties (including communications
         and/or computer equipment leased by Grantor to such third parties) to
         enable Grantor to provide such third parties with broadband
         connectivity to the internet, IP VPN services, and/or all other
         internet, intranet and extranet facilities and equipment and/or
         services then currently being provided by Grantor; (ii) the use,
         maintenance, repair, and operation of such communications and/or
         computer equipment by such third parties and/or by Grantor; and (iii) a
         grant by Grantor to such third parties of the right to have actual
         and/or virtual access to the Building and to such communications and/or
         computer equipment (each such third party is a "Co-location Party"; the
         equipment of, owned, leased or otherwise belonging to the Co-location
         Party is the "Co-location Equipment" and the arrangements between
         Grantor and a Co-location Party consistent with (i)-(iii) above being
         the "Permitted Co-location Arrangements"). Notwithstanding the
         foregoing, Permitted Co-location Arrangements may be effected whether
         or not Grantor provides managed hosting services to the Co-location
         Party.

(3)      INSURANCE. Until this Deed of Trust has been released in accordance
         with Paragraph 17 below, Grantor shall maintain the following insurance
         and otherwise comply with the provisions of this Section (3):

                  (i) Grantor shall provide and maintain, at Grantor's sole cost
         and expense throughout the duration of this Deed of Trust, commercial
         general liability insurance, including blanket contractual liability
         coverage (or its equivalent) specifically endorsed to provide coverage
         for the obligations assumed by Grantor pursuant to this Deed of Trust,
         against claims and liability for personal injury, bodily injury, death,
         or property damage occurring on, in, or about the Mortgaged Property,
         with limits of liability of not less than Five Million Dollars
         ($5,000,000.00) for liability arising out of any one occurrence;

                  (ii) insurance insuring Grantor against loss or damage to the
         Mortgaged Property by fire, lightning, windstorm, hail, explosion,
         aircraft, smoke, vandalism, malicious mischief, vehicle damage and
         other risks from time to time included under a so called "Special Form
         Causes of Loss" policy (or its equivalent) together with earthquake
         and, if the Mortgaged Property is located in a special flood hazard
         area, flood insurance and such other similar policies as Beneficiary
         may reasonably require to protect the Mortgaged Property. Such
         insurance shall provide coverage in an amount sufficient to prevent
         Grantor from being a co-insurer of any loss under the policy or
         policies, but in no event less than 100% of the full replacement cost
         of the improvements;

                  (iii) At all times during the duration of this Deed of Trust
         when fuel tanks are located at or on any land on which any Building is
         constructed, Grantor shall maintain so called "Above Ground Storage
         Tank Third Party Liability and Cleanup" insurance or its equivalent.
         Notwithstanding anything to the contrary in this Deed of Trust, such
         insurance shall be on a claims made basis with a per occurrence limit
         of at least One Million Dollars ($1,000,000) and a general aggregate
         limit of at least One Million Dollars ($1,000,000) with reasonable
         deductibles and reasonable coverage for defense costs.

         All of the foregoing insurance will be issued by an insurance company
         of recognized financial standing having at least an A+ rating by Best
         Insurance Reports. Said policies shall be in form as are reasonably
         acceptable to and approved by Beneficiary. All such insurance policies
         are assigned to and are to be held by and, to the extent of its
         interest, for the benefit of and payable in case of loss to the
         Beneficiary, and Grantor will deliver to Beneficiary such policies,
         marked "Paid", and new policies as replacement for any expiring
         policies at least fifteen (15) days before the date of such expiration.
         All such policies of insurance shall have attached the standard
         non-contributory first mortgagee clause or its equivalent in favor of
         Beneficiary, with cancellation only upon at least fifteen (15) days'
         prior written notice to Beneficiary. All amounts recoverable under any
         such policies or to which Grantor is otherwise entitled from third
         parties are hereby assigned to Beneficiary and, in the event of a loss,
         each insurance company or other third party concerned is authorized and
         directed to make payment for such loss directly to Beneficiary alone
         and Beneficiary is hereby authorized to adjust, compromise, receive,
         collect and sue for the same and Grantor hereby authorizes and directs
         that such sum or sums be paid to Beneficiary upon presentation of a
         duly certified copy hereof. Beneficiary is further authorized to
         endorse Grantor's name upon any check in payment of loss. All loss
         proceeds received by Beneficiary shall be applied as follows: (i)
         first, to fund the replacement, repair and restoration to and/or of the
         Mortgaged Property taken or injured if Grantor elects to effect such
         replacement, repair and/or restoration, (ii) next, any remaining funds
         to be applied against the Indebtedness secured hereby to the extent
         then due and unpaid without the application of any prepayment penalty
         and applied

                                      -4-

<PAGE>


         to principal and interest as provided in the Notes, and (iii) next, any
         remaining funds to be paid to Grantor. All of the policies of insurance
         shall be held by Beneficiary as additional security and, in the event
         of a sale of the Mortgaged Property upon foreclosure, all right, title
         and interest of Grantor in and to such policies of insurance shall pass
         to the purchaser at such sale and Grantor irrevocably appoints
         Beneficiary as attorney-in-fact of Grantor to assign any policies or
         proceeds thereof to such purchaser.

         The following notice is provided pursuant to Section 427.120, R.S.Mo.
         As used herein, "you" means Grantor and "we" means Beneficiary: UNLESS
         YOU PROVIDE EVIDENCE OF THE INSURANCE COVERAGE REQUIRED BY YOUR
         AGREEMENT WITH US, WE MAY PURCHASE INSURANCE AT YOUR EXPENSE TO PROTECT
         OUR INTERESTS IN YOUR COLLATERAL. THIS INSURANCE MAY, BUT NEED NOT,
         PROTECT YOUR INTERESTS. THE COVERAGE THAT WE PURCHASE MAY NOT PAY ANY
         CLAIM THAT YOU MAKE OR ANY CLAIM THAT IS MADE AGAINST YOU IN CONNECTION
         WITH THE COLLATERAL. YOU MAY LATER CANCEL ANY INSURANCE PURCHASED BY
         US, BUT ONLY AFTER PROVIDING EVIDENCE THAT YOU HAVE OBTAINED INSURANCE
         AS REQUIRED BY OUR AGREEMENT. IF WE PURCHASE INSURANCE FOR THE
         COLLATERAL, YOU WILL BE RESPONSIBLE FOR THE COSTS OF THAT INSURANCE,
         INCLUDING THE INSURANCE PREMIUM, INTEREST AND ANY OTHER CHARGES WE MAY
         IMPOSE IN CONNECTION WITH THE PLACEMENT OF THE INSURANCE, UNTIL THE
         EFFECTIVE DATE OF THE CANCELLATION OR EXPIRATION OF THE INSURANCE. THE
         COSTS OF THE INSURANCE MAY BE ADDED TO YOUR TOTAL OUTSTANDING BALANCE
         OR OBLIGATION. THE COSTS OF THE INSURANCE MAY BE MORE THAN THE COST OF
         INSURANCE YOU MAY BE ABLE TO OBTAIN ON YOUR OWN.

(4)      INDEMNITY. Grantor will protect, indemnify, defend and hold harmless
         Trustee and Beneficiary from and against any and all claims, causes of
         action, suits, liabilities, damages (exclusive of consequential and
         incidental damages), losses, costs and expenses (including attorneys'
         fees), of whatever nature, which may arise or result, directly or
         indirectly by reason of the use or occupation of the Mortgaged Property
         by Grantor or any part thereof or any failure by Grantor to comply with
         the covenants contained herein.

(5)      REPAIRS. Grantor will at all times keep and maintain the Mortgaged
         Property and every part thereof in good order, repair and condition,
         without any liability of Trustee or Beneficiary to any person for
         damage for failure to repair or for any other cause, and Grantor will
         promptly make all needed and proper repairs, restorations, renewals and
         replacements thereof, so that at all times the value of the Mortgaged
         Property and every part thereof shall be fully preserved and
         maintained, and Grantor will not cause or permit any waste on or of the
         Mortgaged Property or otherwise allow the Mortgaged Property, or any
         part thereof, to depreciate in value by any act or neglect.

(6)      COMPLIANCE. Grantor will not use or suffer or permit to be used the
         Mortgaged Property or any part thereof in any manner inconsistent with
         the rights of Trustee or Beneficiary hereunder, or in violation of the
         provisions of any insurance policy or any rules or regulations of
         insurance underwriters, and will comply with, and maintain, use and
         cause the Mortgaged Property to at all times be in compliance with all
         laws, ordinances, rules, regulations, orders and directions of any
         legislative, executive, administrative or judicial body, officer or
         department applicable to the Mortgaged Property or to the uses or
         purposes thereof.

(7)      CONDEMNATION. In the event the Mortgaged Property, or any part thereof,
         be taken through condemnation proceedings or by virtue of the exercise
         of the right of eminent domain or pursuant to governmental action, any
         and all amounts awarded in any such condemnation proceeding for the
         taking of the Mortgaged Property, or any part thereof, are hereby
         assigned to and shall be paid to Beneficiary, and when received by
         Beneficiary, shall be applied as follows: (i) first, to fund the
         replacement, repair and restoration to and/or of the Mortgaged Property
         taken or injured if

                                      -5-

<PAGE>

         Grantor elects to effect such replacement, repair and/or restoration,
         (ii) next, any remaining funds to be applied against the Indebtedness
         secured hereby to the extent then due and unpaid without the
         application of any prepayment penalty and applied to principal and
         interest as provided in the Notes, and (iii) next, any remaining
         funds to be paid to Grantor.

(8)      SEVERABILITY. To the extent that any grant under this Deed of Trust
         violates the terms of any other agreement to which Grantor is a party
         as of the date of this Deed of Trust, such grant shall be deemed
         severed from this Deed of Trust and shall be deemed to be null and void
         and of no force or effect as of the date of this Deed of Trust and the
         remainder of this Deed of Trust shall remain in full force and effect
         to extent permitted by law and this Deed of Trust shall be deemed
         amended as appropriate to give effect to such severance.

(9)      TAXES. Grantor hereby covenants and agrees to pay any and all taxes,
         assessments, liens and other charges that may be levied or assessed
         against the Mortgaged Property, or any part thereof, prior to the time
         the same shall become delinquent, and Grantor shall promptly provide
         Beneficiary with proof of payment thereof.

(10)     CHANGE IN TAXATION LAWS. In the event of the enactment after the date
         hereof of any law of the State of Missouri or the United States of
         America imposing a specific tax on notes, bonds, or other evidences of
         indebtedness or obligations secured by a mortgage or deed of trust on
         real estate, or in the event the laws now in force relating to taxes on
         notes, mortgages, bonds, or other evidences of indebtedness or
         obligations secured by mortgage or deed of trust shall be in any manner
         changed, or in case such a tax shall be assessed under any existing
         law, as the result of which Trustee or Beneficiary may become
         chargeable with the payment of any such taxes, then and in any such
         event, Grantor covenants and agrees to pay to Trustee or Beneficiary,
         within thirty (30) days after written notice thereof, the amount of any
         such tax; provided that if Trustee or Beneficiary shall be required by
         law to pay any such tax, all moneys so expended shall be due on demand,
         bear interest at the highest rate set forth in the Notes (or if no rate
         is specified, at the maximum lawful rate) and shall be secured hereby.
         In the event Grantor shall fail to pay or cause to be paid or to
         reimburse Trustee or Beneficiary for advances as aforesaid to pay any
         such tax or taxes, or if by such law it should be illegal for Grantor
         to pay any such tax or taxes, then all of the Indebtedness secured
         hereby shall, at the option of Beneficiary, become immediately due and
         payable without further notice, anything herein or in the evidences of
         any indebtedness or other obligations secured by this Deed of Trust to
         the contrary notwithstanding; provided, however, that Grantor shall not
         be required to pay any such tax in excess of an amount which when added
         to the interest paid by Grantor on the Indebtedness would exceed the
         maximum lawful rate allowed in the State of Missouri.

(11)     CURE PAYMENTS. If Grantor shall fail to pay any tax, assessment, lien
         or other charge levied or assessed against the Mortgaged Property, or
         any part thereof, or shall fail to keep and perform any of the
         covenants and conditions herein contained, Trustee or Beneficiary,
         shall be privileged, but shall not be obligated, to pay any such tax,
         assessment, lien, rent or other charge, to redeem such property from
         any sale or foreclosure for taxes or assessments or liens, to effect
         and pay for insurance required hereunder, to perform or pay for any
         other obligations, and to make such other disbursements as are
         necessary or advisable in the opinion of Trustee or Beneficiary to cure
         any default of Grantor hereunder or protect the lien or the rights of
         Trustee and Beneficiary hereunder; any and all such sums of money
         advanced for such purposes by Trustee or Beneficiary shall be deemed
         additional Indebtedness secured by this Deed of Trust and shall be
         payable on demand with interest accruing from the time so advanced at
         the highest rate per annum set forth under the Notes (or if no rate is
         specified, at the maximum lawful rate), and failure on the part of

                                     -6-

<PAGE>

         Grantor to repay the amounts so advanced on demand shall constitute an
         event of default hereunder; provided, however, nothing herein contained
         shall be construed as requiring Trustee or Beneficiary to effect such
         insurance or to advance or expend money or take any action for any of
         the purposes aforesaid.

(12)     FINANCIAL INFORMATION. Grantor shall furnish the financial statements
         as and when required to be provided by Grantor pursuant to and in
         accordance with the Securities Purchase Agreement.

(13)     SECURITY AGREEMENT. This instrument is intended to be a security
         agreement pursuant to the Uniform Commercial Code for any of the items
         specified as part of the Mortgaged Property which, under applicable
         law, may be subject to a security interest pursuant to the Uniform
         Commercial Code, and Grantor hereby grants Beneficiary a security
         interest in said items, whether now owned or hereafter acquired.
         Grantor agrees that Beneficiary may file this instrument, or a
         reproduction thereof, in the real estate records or other appropriate
         index, as a financing statement for any of the items specified as part
         of the Mortgaged Property. Any reproduction of this instrument or of
         any other security agreement or financing statement shall be sufficient
         as a financing statement. In addition, Grantor agrees to execute and
         deliver to Beneficiary, upon Beneficiary's request, any financing
         statements, as well as extensions, renewals and amendments thereof, and
         reproductions of this instrument, in such form as Beneficiary may
         require to perfect a security interest with respect to said items.
         Grantor shall pay all costs of filing such financing statements and any
         extensions, renewals and amendments thereof, and shall pay all
         reasonable costs and expenses of any record searches for financing
         statements Beneficiary may reasonably require. Without the prior
         written consent of Beneficiary, Grantor shall not create or suffer to
         be created pursuant to the Uniform Commercial Code any other security
         interest in said items, including replacements and additions thereto.
         Upon the occurrence of an event of default as hereinafter provided,
         Beneficiary shall have the remedies of a secured party under the
         Uniform Commercial Code and, at Beneficiary's option, may also invoke
         the remedies as otherwise provided in this instrument. In exercising
         any of said remedies, Beneficiary may proceed against the items of
         property specified as part of the Mortgaged Property separately or
         together and in any order whatsoever, without in any way affecting the
         availability of Beneficiary's remedies under the Uniform Commercial
         Code or of the remedies otherwise provided in this instrument.

(14)     EXCLUDED PROPERTY. Beneficiary hereby acknowledges that it has no
         security interest in any of the Excluded Property nor is Grantor's
         interest or the interest of any third party in any Excluded Property
         subordinate or subject to this Deed of Trust or any security interest
         in favor of Beneficiary for Grantor. Beneficiary will execute and
         deliver to Grantor such reasonable instruments as Grantor may from time
         to time request confirming the provisions of this Paragraph 14 in such
         reasonable form as Grantor may request.

(15)     GROUND LEASE. Grantor shall have the right, without the prior written
         consent of Beneficiary, to enter into a ground lease with the fee owner
         of the Land on such terms as determined to be necessary and appropriate
         by Grantor. Grantor shall further have the right to record a memorandum
         of such ground lease in the records of the County of St. Louis, State
         of Missouri. In such event, such ground lease shall be superior to this
         Deed of Trust; provided, however, Grantor shall, upon obtaining all
         necessary third party consents, grant a leasehold deed of trust
         respecting Grantor's leasehold interest to Beneficiary on such terms
         and conditions as are mutually acceptable to Grantor and Beneficiary
         and consistent with the terms of this Deed of Trust.

(16)     SUBORDINATE TO FIRST DEED OF TRUST. Notwithstanding anything to the
         contrary in this Deed of Trust, the rights granted by Grantor to
         Beneficiary under this Deed of Trust respecting all portions of the
         Mortgaged Property are at all times subject and subordinate to the
         following: (i) rights and interests of the holder of fee simple title
         to the Land and to the First Deed of Trust and any renewals,
         modifications, replacements, and extensions of such First Deed of Trust
         thereof to the extent that any of the Mortgaged Property is subject to
         such First Deed of Trust; and (ii) the Missouri Future Advance Deed of
         Trust dated as of February 19, 2001 and recorded on February 20, 2001
         in the records of the St. Louis County Recorder of Deeds as Daily
         Number 450, as amended ("WCAS Deed of Trust"). Grantor shall not be in
         default under this Deed of Trust or be deemed to have breached any
         representations under this Deed of Trust in the event and to the extent
         that Beneficiary's rights under this Deed of Trust are so subordinate.
         Further, Beneficiary agrees that it will execute such reasonable
         agreements and instruments as may be required by Grantor and/or its
         lenders to further evidence such subordination.

(17)     RELEASE. If all of Grantor's covenants and agreements under this Deed
         of Trust are performed in full and either (i) the debt described in the
         Convertible Senior Secured Notes is paid when due or (ii) the then
         outstanding principal amount of the Convertible Senior Secured Notes
         plus all accrued interest on such principal amount is converted into
         equity securities of Borrower pursuant to the Notes, then these
         presents shall be void and this Deed of Trust shall be released with
         all recording costs associated with recording any necessary release to
         be paid by Grantor.

(18)     NO THIRD PARTY RIGHTS OR INTERESTS AFFECTED. Grantor, by this
         instrument, does not and does not intend to mortgage, pledge, alter or
         interfere in any way whatsoever, with the rights of any party(ies) not
         a party hereto. Specifically and without limitation, Grantor by this
         instrument does not and shall not be deemed to have taken any action
         against any property of the estate of Bridge Information Systems, Inc.,
         a Missouri corporation, or any of its affiliates which are
         debtors-in-possession in bankruptcy cases presently proceeding in the
         United States Bankruptcy Court for the Eastern District of Missouri,
         Eastern Division, Cases No. 01-0141593-293 through 01-0141614-293,
         inclusive (collectively, herein the "Debtor"), or to act or attempt to
         act to (i) take or transfer any interest in property of Debtor's
         estate, (ii) create, perfect, or enforce any lien against property of
         Debtor's estate, (iii) create, perfect or enforce any pre-petition lien
         against property of Debtor's estate, (iv) collect or recover any
         pre-petition claim against Debtor or its estate, or (v) to set off the
         interests herein granted against any pre-petition claim against the
         Debtor. This instrument conveys a quitclaim security interest against
         the property rights, if any, in the Mortgaged Property and against
         these rights, if any, only.

(19)     DELIVERY OF NON-DISTURBANCE AGREEMENT. Upon the request of Grantor,
         Beneficiary will execute and deliver a non-disturbance and attornment
         agreement in favor of all users, occupants and subtenants of the
         Mortgaged Property confirming that in the event of a foreclosure of
         this Deed of Trust, the purchaser of the Mortgaged Property at the
         foreclosure sale will recognize and not disaffirm or disturb either the
         agreements between Grantor and any such users, occupants and subtenants
         or the use and occupancy of the Mortgaged Property by such users,
         occupants and subtenants in accordance with such agreements all of
         which such agreements and such uses shall continue in full force and
         effect in accordance with their terms.

(20)     COUNTERPARTS. This Deed of Trust may be executed in several
         counterparts, with signature to one such counterpart being deemed
         signature to all such counterparts, each of which shall be deemed an
         original and all of which taken together shall constitute one and the
         same instrument.

(21)     FURTHER ADVANCES. This Deed of Trust is to be governed by Section
         443.055 of the revised Statues of Missouri. In the event Grantee shall
         receive a notice pursuant to Section 443.055 of the Revised Statues of
         Missouri terminating this Deed of Trust as security for future advances
         for future obligations made or incurred after the date of such notice,

         obligation under the Notes, any document evidencing, securing or
         related to the indebtedness secured by this Deed of Trust
         notwithstanding anything to the contrary in any such document.

(22)     EVENTS OF DEFAULT; REMEDIES. If an event of default as specifically set
         forth herein shall occur, or in the event any one or more of the
         following events shall occur (an "event of default"): (a) If default
         shall be made in the payment of any of the Indebtedness secured hereby,
         or any interest thereon, as and when the same shall become due and
         payable, whether by reason of demand, acceleration or otherwise; (b) If
         default shall be made by Grantor in the due performance or observance
         of any covenant, agreement or condition herein contained or required to

         a period of ten (10) days after the date of the mailing of a written

         such other address as may be designated by Grantor in written notice
         delivered to Beneficiary; (c) If Grantor interest in the Mortgaged
         Property shall pass by operation of law as the result of any creditor's
         action, suit or proceeding or if any of the foregoing shall occur with
         respect to any guarantor of the Indebtedness secured hereby; (d) If the
         Mortgaged Property or any portion thereof or ownership interest therein
         is sold, transferred, assigned or in any manner conveyed without the
         prior written consent of Beneficiary; (e) If a default or event of
         default shall occur under or within the meaning of any other deed of
         trust or mortgage covering any of the Mortgaged Property after giving
         effect to all applicable cure periods; (f) the occurrence of an event
         of default under the Notes after giving effect to all applicable cure
         periods; or (g) if pursuant to ss. 443.055 R.S.Mo., as amended, Grantor
         shall notify Beneficiary of Grantor's election to terminate the
         operation of this Deed of Trust as security for future advances or
         future obligations;

THEN, AND IN EACH AND EVERY SUCH EVENT: (1) All of the Indebtedness then
outstanding and unpaid and all accrued and unpaid interest thereon shall, at the
option of Beneficiary, become and be due and payable immediately, anything in
the Notes evidencing any of the Indebtedness or in this Deed of Trust to the
contrary notwithstanding; (2) Upon demand of Trustee or Beneficiary, Grantor
shall forthwith surrender to Beneficiary the actual possession of all of the
Mortgaged Property and it shall be lawful (whether or not Grantor has so
surrendered possession) for Beneficiary, either personally or by agents or
attorneys, forthwith to enter into or upon the Mortgaged Property and to exclude
Grantor, the agents and servants of Grantor, and all parties claiming by,
through or under Grantor, wholly therefrom, and Beneficiary shall thereupon be
solely and exclusively entitled to possession of said Mortgaged Property and
every part thereof, and to use, operate, manage and control the same, either
personally or by managers, agents, servants or attorneys, to the fullest extent
authorized by law; and upon every such entry, the Beneficiary may, from time to
time, at the expense of Grantor, make all necessary and proper repairs and
replacements to the Mortgaged Property as Beneficiary in its discretion sees
fit, and any amounts so expended shall be due on demand, bear interest at the
post-maturity rate set forth in the Notes and shall be secured hereby; (3)
Trustee, at the request of Beneficiary, shall proceed to sell, either by himself
or by agent or attorney, the Mortgaged Property or any part(s) thereof at public
vendue or outcry at the customary place to the highest bidder for cash after
first giving notice as required by the statutes of the State of Missouri and
upon such sale Trustee shall receive the proceeds of such sale and shall execute
and deliver deed or deeds or other instruments of conveyance, assignment and
transfer to the property sold, to the purchaser or purchasers thereof; and (4)
Trustee and/or Beneficiary may proceed by suit or suits at law or in equity to
enforce the Indebtedness secured hereby and/or to foreclose this Deed of Trust

                                      -9-

<PAGE>

and in such event Trustee shall be entitled to a reasonable fee for his services
and Trustee and Beneficiary shall be entitled to a reasonable fee for the
services of their attorneys and agents, and for all expenses, costs and outlays.
Upon or at any time after the filing of any suit to foreclose the lien hereof,
Beneficiary shall be entitled as a matter of right to the appointment of a
receiver of the Mortgaged Property, either before or after sale, without notice
and without regard to the solvency or insolvency of Grantor at the time of the
application for such receiver, and without regard to the solvency or insolvency
of Grantor at the time of the application for such receiver, and without regard
to the then value of the Mortgaged Property, and Trustee, or Beneficiary, may be
appointed as such receiver. Such receiver shall have all powers necessary or
incidental for the protection, possession, control, management and operation of
the Mortgaged Property.

         In any sale or sales made by Trustee under the power herein granted, or
upon any sale or sales under or by virtue of any judicial proceedings: (i) the
whole of the Mortgaged Property may be sold in one parcel as an entirety, or the
Mortgaged Property may be sold in separate parcels as may be determined by
Trustee in his discretion; (ii) all recitals contained in any deed or other
instrument of conveyance, assignment or transfer made and delivered by Trustee
in pursuance of the powers granted and conferred herein, shall be prima facie
evidence of the facts therein set forth; (iii) such sale or sales shall operate
to divest Grantor of all right, title, interest, claim and demand, either at law
or in equity, under statute or otherwise, in and to the Mortgaged Property and
every part thereof so sold and shall be a perpetual bar, both in law or equity,
against Grantor and any and all persons claiming or to claim from, through or
under Grantor; and (iv) Beneficiary may bid for and purchase the Mortgaged
Property or any part thereof and may make payment therefor by presenting to
Trustee the Notes secured hereby or the other evidences of the Indebtedness
secured hereby so that there may be endorsed as paid thereon the amount of such
bid which is to be applied to the payment of the Indebtedness secured hereby as
herein provided. Each time it shall become necessary to insert an advertisement
of foreclosure, and sale is not had, Trustee shall be entitled to receive the
sum of One Hundred Dollars ($100.00) for services and the amount of all
advertising charges from Grantor, all of which shall be further secured hereby.
Upon the foreclosure and/or sale of the Mortgaged Property, or any part thereof,
the proceeds of such sale or sales shall be applied as follows: First, to the
cost and expense of executing this trust, including reasonable compensation of
Trustee and reasonable attorneys' fees and expenses, outlays for documentary
stamps, cost of procuring title insurance commitments, continuing abstracts,
title searches or examinations reasonably necessary or proper; next, to the
payment of any and all advances made by Trustee or Beneficiary, with interest
thereon as hereinabove provided; next, to the payment of the balance of the
Indebtedness secured hereby, with interest thereon as therein provided; and any
surplus thereafter shall be paid to Grantor or any other party legally entitled
thereto; provided that in the event the net proceeds of such sale or sales shall
not be sufficient to pay in full the Indebtedness secured hereby, Grantor hereby
promises and agrees to pay any deficiency thereon on demand with interest.

         Grantor shall not apply for or avail itself of any appraisement,
valuation, redemption, stay, extension or exemption laws, or any so-called
"moratorium laws", now existing or hereafter enacted, in order to prevent or
hinder the enforcement or foreclosure of this Deed of Trust, and hereby waives
the benefit of such laws. Grantor, for itself, its successors and assigns,
hereby wholly waives the period of redemption and any right of redemption
provided under any existing or future law in the event of a foreclosure of this
Deed of Trust. Grantor, for itself and all who may claim through or under it,
hereby waives any and all right to have the property and estates comprising the
Mortgaged Property marshalled upon any foreclosure of the lien hereof and hereby
agrees that any court having jurisdiction to foreclose such lien may order the
Mortgaged Property sold as an entirety. Grantor hereby waives any order or
decree of foreclosure, pursuant to the rights herein granted, on behalf of the
Grantor, and each and every person acquiring any interest in or title to the
Mortgaged Property, subsequent to the date of this Deed of Trust, and on behalf
of all other persons to the extent permitted by applicable law.

                                      -10-

         The Trustee may resign at any time by written instrument to that effect
delivered to Beneficiary. Beneficiary shall be entitled to remove, at any time
and from time to time, including any time before, during or after the
commencement or completion of any foreclosure proceeding, the Trustee. In case
of the death, removal, resignation, refusal to act or otherwise being unable to
act of the Trustee, Beneficiary shall be entitled to select and appoint a
successor Trustee hereunder by an instrument duly executed, acknowledged and
recorded in the manner and form for conveyances of real estate in the State of
Missouri, which recording may occur before, during or after the commencement or
completion of any foreclosure proceeding, and any such successor Trustee shall
thereupon succeed to Trustee as Trustee hereunder and to all of the rights,
powers, duties, obligations and estate of said Trustee as if specifically named
herein, provided no defect or irregularity in the resignation or removal of said
Trustee or in the appointment of a successor Trustee or in the execution and
recording of such instrument shall affect the validity of said resignation,
removal or appointment or any act or thing done by such successor Trustee
pursuant thereto. Additionally, whether the recording of the successor Trustee
instrument takes place before, during or after the commencement or completion of
any foreclosure proceeding shall have no effect upon the validity of said
proceeding. Trustee shall not be disqualified from acting as Trustee hereunder
or from performing any of the duties of Trustee, or from exercising the rights,
powers and remedies herein granted, by reason of the fact that Trustee is an
officer, employee or stockholder of Beneficiary, or is interested, directly or
indirectly, as the holder of the Convertible Senior Secured Notes or other
Indebtedness secured hereby, Grantor hereby expressly consenting to Trustee
acting as Trustee irrespective of the fact that Trustee might be otherwise
disqualified for any of the foregoing reasons, and that any interest which
Trustee or any successor shall have or may acquire in the Indebtedness secured
hereby, or the Mortgaged Property, shall neither interfere with nor prevent his
acting as Trustee or from purchasing said property at said sale or sales, and
all parties waive any objection to Trustee having or acquiring any such interest
in the Indebtedness or Mortgaged Property and continuing to act as Trustee.
Trustee covenants faithfully to perform and fulfill the trust herein created,
but shall be liable, however, only for gross negligence or willful misconduct as
determined by a court of competent jurisdiction.

         No remedy herein conferred upon or reserved to Trustee or Beneficiary
is intended to be exclusive of any other remedy, but every remedy herein
provided shall be cumulative, and shall be in addition to every other remedy
given hereunder or now or hereafter existing at law or in equity, or by statute;
and every power and remedy given by this Deed of Trust to Trustee or to
Beneficiary may be exercised from time to time and as often as may be deemed
expedient. No delay or omission by Trustee or by Beneficiary to exercise any
right or power arising from any default shall impair any such right or power or
shall be construed to be a waiver of any default or an acquiescence therein. In
case Trustee shall have proceeded to enforce any right under this Deed of Trust
by foreclosure, entry or otherwise, and such proceedings shall have been
discontinued or abandoned because of waiver or for any other reason, or shall
have been determined adversely, then, and in such and every such case, Grantor
and Trustee shall severally and respectively be restored to their former
positions and rights hereunder in respect of the Mortgaged Property, and all
rights, remedies and powers of Trustee shall continue as though no such
proceedings had been taken. If any additional sum or sums shall become due and
owing, by Grantor to Beneficiary, pursuant to the provisions hereof, the
affidavit of Beneficiary shall be sufficient evidence of the fact that such
additional sums are secured hereby in the amount set forth in such affidavit.

(23)     GENERAL PROVISIONS. This Deed of Trust and all provisions hereof shall
         extend to and be binding upon Grantor and all parties claiming by,
         through or under Grantor. All covenants and agreements of Grantor
         herein shall be joint and several. Grantor acknowledges and agrees that
         all expenses and amounts expended by Trustee and/or Beneficiary or owed
         to Trustee or Beneficiary under any indemnity in this Deed of Trust,
         shall be due as and when incurred, bear interest at the highest rate
         set forth in the Notes and the Securities Purchase Agreement (the "Debt

                                      -11-

<PAGE>

         Instruments") (or if no rate is specified, at the maximum lawful rate)
         and shall constitute Indebtedness secured hereby, and all indemnities
         contained in this Deed of Trust shall apply notwithstanding any
         negligent conduct or omission of Beneficiary or Trustee (except to the
         extent of gross negligence or willful misconduct on the part of
         Beneficiary or Trustee), are in addition to any legal liability or
         responsibility Grantor otherwise has, and shall survive the foreclosure
         of this Deed of Trust and the payment of the obligations secured
         hereunder. The unenforceability or invalidity of any provision or
         provisions of this Deed of Trust shall not render any other provision
         or provisions herein contained unenforceable or invalid. The term
         "Beneficiary" shall be deemed to mean and include the endorsee(s),
         transferee(s) or the holder(s) at the time being of the Debt
         Instruments and/or any of the other Indebtedness secured hereby, and
         the successors and assigns of Beneficiary, and the term "Trustee" shall
         be deemed to mean and include any successors of the Trustee in the
         trust hereby created; and the covenants and agreements shall bind and
         inure to the benefit of the heirs, executors, personal representatives,
         successors and assigns of Grantor and the successors in trust of the
         Trustee and the endorsee(s), transferee(s), successors and assigns of
         Beneficiary. All of the grants, covenants, terms, agreements,
         provisions and conditions herein contained shall run with the land.
         Time is of the essence of all Grantor's obligations hereunder. The
         captions or headings used herein are for the convenience of the parties
         and are not a part of this Deed of Trust. To the extent that proceeds
         of the Indebtedness secured hereby or advances under this Deed of Trust
         are used to pay any outstanding lien, charge or prior encumbrance
         against the Mortgaged Property, Beneficiary is hereby subrogated to any
         and all rights and liens held by any owner or holder of such
         outstanding liens, charges and prior encumbrances, irrespective of
         whether said liens, charges or encumbrances are released. Trustee
         hereby lets the Mortgaged Property to Grantor and assigns until this
         Deed of Trust be released and satisfied, or until default be made under
         the covenants and agreements hereof, upon the following terms, to-wit:
         Grantor and all persons claiming or possessing said Mortgaged Property
         or any part thereof, shall pay rent therefor during said term at one
         cent per month, payable on demand, and shall and will surrender
         peaceful possession of said premises, and every part thereof, to
         Trustee immediately upon such default, and without notice or demand
         therefor, provided that nothing in this Deed of Trust shall be
         construed to prevent the Beneficiary from having and taking every legal
         means to enforce payment of the Indebtedness secured hereby, without
         having first enforced this Deed of Trust; provided, further that if
         Grantor shall well and truly pay or cause to be paid to Beneficiary the
         Indebtedness secured hereby as and when the same shall become due and
         payable and this Deed of Trust is no longer intended to secure future
         advances and future obligations under Section 443.055 R.S.Mo., as
         amended, then this trust shall cease and be void and the Mortgaged
         Property hereinbefore conveyed shall be released at the cost of
         Grantor, otherwise to remain in full force and effect. To the extent
         that Beneficiary receives any payment on account of the Indebtedness
         and any such payment(s) or any part thereof is subsequently
         invalidated, declared to be fraudulent or preferential, set aside,
         subordinated and/or required to be repaid to a trustee, receiver or any
         other party under any bankruptcy act, state or federal law, common law
         or equitable cause, then, to the extent of such payment(s) received,
         the Indebtedness or part thereof intended to be satisfied and any and
         all liens, security interests, mortgages and/or other encumbrances upon
         or pertaining to any assets of Grantor and theretofore created and/or
         existing in favor of Beneficiary as security for the payment of such
         Indebtedness shall be revived and continue in full force and effect, as
         if such payment(s) had not been received by Beneficiary and applied on
         account of the Indebtedness. The Recitals above stated are incorporated
         herein by this reference.

(24)     Should at any time the holder of any Note(s) determine to convert the
         indebtedness evidenced thereby into an equity interest in Borrower
         pursuant to the terms of the Securities Purchase Agreement, the
         Notes(s) of such holder shall cease to be "Notes" for purposes hereof
         and shall not be hereby secured, nor shall any equity interest in
         Borrower or rights in securities of Borrower arising under any Notes(s)
         or the Securities Agreement constitute Indebtedness secured by the Deed
         of Trust.

(25)     This Deed of Trust is not effective unless and until the Beneficiary
         under the WCAS Deed of Trust consents in writing to the grant by
