                          COMMON STOCK PURCHASE WARRANT

                            Void after August 5, 2009

         INTEGRATED DEFENSE TECHNOLOGIES, INC. (the "COMPANY"), a Delaware
corporation, hereby certifies that for value received, J.H. WHITNEY MEZZANINE
FUND, L.P. ("WMF"), a Delaware limited partnership, or its successors or assigns
(the "HOLDER"), is entitled to purchase, subject to the terms and conditions
hereinafter set forth, at any time or beginning on the date hereof and prior to
5:00 P.M., New York City time, on August 5, 2009 (the "EXPIRATION DATE"), an
aggregate of 5,556 fully paid and nonassessable shares of Common Stock (as
hereinafter defined) of the Company, at an exercise price of $.01 per share (the
"PURCHASE PRICE"), subject to adjustment as provided herein,

         This Warrant is issued pursuant to the Securities Purchase Agreement
(the "PURCHASE AGREEMENT"), dated as of the date hereof, among the Company, PEI
Electronics, Inc., SierraTech, Inc. and WMF, and is subject to the terms
thereof. Capitalized terms used herein and not otherwise defined shall have the
meanings assigned to such terms in the Purchase Agreement. The Holder is
entitled to the rights and subject to the obligations contained in the Purchase
Agreement and the Stockholders' Agreement relating to this Warrant and the
shares of Common Stock issuable upon exercise of this Warrant.
<Page>

         1. DEFINITIONS. For the purposes of this Warrant, the following terms
shall have the meanings indicated:

                  "APPLICABLE PRICE" shall mean the higher of (a) the Current
Market Price per share of Common Stock on the applicable record or other
relevant date and (b) the Dilution Price.

                  "BUSINESS DAY" shall mean any day other than a Saturday,
Sunday or other day on which commercial banks in the City of New York are
authorized or required by law or executive order to close.

                  "CLOSING PRICE" shall mean, with respect to each share of
Common Stock for any day, (a) the last reported sale price regular way or, in
case no such sale takes place on such day, the average of the closing bid and
asked prices regular way, in either case as reported on the principal national
securities exchange on which the Common Stock is listed or admitted for trading
or (b) if the Common Stock is not listed or admitted for trading on any national
securities exchange, the last reported sale price or, in case no such sale takes
place on such day, the average of the highest reported bid and the lowest
reported asked quotation for the Common Stock, in either case as reported on the
NASDAQ or a similar service if NASDAQ is no longer reporting such information.

                  "COMMON STOCK" means the common stock, par value $0.01 per
share, of the Company, and any class of stock resulting from successive changes
or reclassification of such Common Stock.

                  "COMPANY" shall have the meaning ascribed to such term in the
first paragraph of this Warrant.

                  "CURRENT MARKET PRICE" shall mean the average of the daily
Closing Prices per share of Common Stock for the 10 consecutive trading days
commencing 15 trading days before the date on which Current Market Price is to
be determined. If on any such date the shares of Common Stock are not listed or
admitted for trading on any national securities exchange or quoted by NASDAQ or
a similar service, then the Company, on the one hand, and the holder of this
Warrant on the other hand, shall each promptly appoint as an appraiser an
individual who shall be a member of a nationally recognized investment banking
firm. Each appraiser shall be instructed to, within 30 days of appointment,
determine the Current Market Price per share of Common Stock which shall be
deemed to be equal to the fair market value per share of Common Stock as of such
date. If the two appraisers are unable to agree on the Current Market Price per
share of Common Stock within such 30 day period, then the two appraisers, within
10 days after the end of such 30 day period shall jointly select a third
appraiser. The third appraiser shall, within 30 days of its appointment,
determine, in good faith, the Current Market Price per share of Common Stock and
such determination shall be controlling. If any party fails to appoint an
appraiser or if one of the two initial appraisers fails after appointment to
submit its appraisal within the required period, the appraisal submitted by the
remaining appraiser shall be controlling. Current Market Price per share of
Common Stock shall be determined without regard to any minority discount
accorded to the shares of Common Stock. The cost of the foregoing appraisals
shall be shared one-half by the Company and one-half by holder of this Warrant,
PROVIDED, HOWEVER, in the event a third appraiser

                                       2
<Page>

is utilized and one of the two initial appraisals (but not the other initial
appraisal) is greater than or less than the appraisal by such third appraiser by
10% or more, then the cost of all of the foregoing appraisals shall be borne by
the party who appointed the appraiser who made such initial appraisal.

                  "DILUTION PRICE" shall mean, with respect to each share of
Common Stock, $540 subject to appropriate adjustment for any stock dividend,
subdivision, combination, reclassification or like event with respect to the
Common Stock.

                  "EXERCISE DATE" shall have the meaning ascribed to such term
in Subsection 2(d).

                  "EXERCISE PRICE" shall mean the Aggregate Purchase Price
divided by the aggregate number of Warrant Shares issuable under this Warrant at
such time.

                  "EXPIRATION DATE" shall have the meaning ascribed to such term
in the first paragraph of this Warrant.

                  "FULLY DILUTED COMMON STOCK" shall mean the number of shares
of Common Stock outstanding as of the relevant time assuming the exercise,
exchange or conversion in full of all rights, warrants (other than this Warrant
and all other warrants issued upon assignment of all or any portion hereof),
options and other securities exercisable or exchangeable for or convertible into
shares of Common Stock (whether or not then exercisable, convertible or
exchangeable), but shall not include any shares issuable upon exercise of
options issued pursuant to Management Options.

                  "HOLDER" shall have the meaning ascribed to such term in the
first paragraph and Section 9(a) of this Warrant.

                  "NASDAQ" shall mean the Automatic Quotation System of the
National Association of Securities Dealers, Inc.

                  "PERSON" shall mean any individual, firm, corporation,
partnership, trust, incorporated or unincorporated association, joint venture,
joint stock company, government (or an agency or political subdivision thereof)
or other entity of any kind, and shall include any successor (by merger or
otherwise) of such entity.

                  "PURCHASE AGREEMENT" shall have the meaning ascribed to such
term in the second paragraph of this Warrant.

                  "PURCHASE PRICE" shall have the meaning ascribed to such term
in the first paragraph of this Warrant.

                  "STOCKHOLDERS AGREEMENT" means the Amended and Restated
Stockholders Agreement in the form attached to the Purchase Agreement as Exhibit
D.

                                       3
<Page>

                  "SUBSIDIARY" shall mean, with respect to any Person, a
corporation or other entity of which 50% or more of the voting power of the
voting equity securities or equity interests is owned, directly or indirectly,
by such Person.

                  "WARRANT" shall mean this Warrant and any subsequent Warrant
issued pursuant to Subsection 2(c).

                  "WARRANT REGISTER" shall have the meaning ascribed to such
term in Subsection 9(c).

                  "WARRANT SHARES" shall mean the shares of Common Stock
issuable upon exercise of this Warrant.

         2. EXERCISE OF WARRANT.

                  (a) EXERCISE. This Warrant may be exercised, in whole only, at
any time and from time to time during the period beginning on the date hereof
and ending on the Expiration Date, by surrendering to the Company at its
principal office this Warrant, with the form of Election to Purchase Shares (the
"ELECTION TO PURCHASE SHARES") attached hereto as EXHIBIT A duly executed by the
Holder and accompanied by payment of the aggregate Purchase Price for the total
number of Warrant Shares.

                  (b) DELIVERY OF SHARES; PAYMENT OF PURCHASE PRICE. As soon as
practicable after surrender of this Warrant and receipt of payment, the Company
shall promptly issue and deliver to the Holder a certificate or certificates for
the number of Warrant Shares for which this Warrant is hereby being exercised,
in such name or names as may be designated by such Holder, along with a check
for the amount of cash to be paid in lieu of issuance of fractional shares, if
any. Payment of the aggregate Purchase Price may be made as follows (or by any
combination of the following): (i) in United States currency by cash or delivery
of a certified check, bank draft or postal or express money order payable to the
order of the Company, (ii) by assigning to the Company all or any part of the
unpaid principal amount of the Note held by the Holder in a principal amount
equal to the aggregate Purchase Price, or (iii) by surrender of a number of
shares of Common Stock held by the Holder equal to the quotient obtained by
dividing (A) the aggregate Purchase Price payable with respect to the exercise
of this Warrant (B) the Current Market Price per share of Common Stock on the
Exercise Date.

                  (c) WHEN EXERCISE EFFECTIVE. The exercise of this Warrant
shall be deemed to have been effective immediately prior to the close of
business on the Business Day on which this Warrant is exercised in accordance
with the provisions of this Section 2 (the "EXERCISE DATE") and the Person in
whose name any certificate for shares of Common Stock shall be issuable upon
such exercise, as provided in Subsection 2(b), shall be deemed to be the record
holder of such shares of Common Stock for all purposes on the Exercise Date.

         3. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. The Purchase
Price and the number of shares of Common Stock issuable upon exercise of this
Warrant shall be adjusted from time to time upon the occurrence of the following
events:

                                       4
<Page>

                  (a) DIVIDEND, SUBDIVISION, COMBINATION OR RECLASSIFICATION OF
COMMON STOCK. If the Company shall, at any time or from time to time, (i)
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock into a
larger number of shares of Common Stock, (iii) combine the outstanding Common
Stock into a smaller number of shares of its Common Stock, or (iv) issue any
shares of its capital stock in a reclassification of the Common Stock (including
any such reclassification in connection with a consolidation or merger in which
the Company is the continuing corporation), then in each such case, the Purchase
Price in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination or reclassification, and the
number and kind of shares of capital stock issuable on such date shall be
proportionately adjusted so that the Holder of any Warrant exercised after such
date shall be entitled to receive, upon payment of the same aggregate amount as
would have been payable before such date, the aggregate number and kind of
shares of capital stock which, if such Warrant had been exercised immediately
prior to such date, such Holder would have owned upon such exercise and been
entitled to receive by virtue of such dividend, subdivision, combination or
reclassification. Any such adjustment shall become effective immediately after
the record date of such dividend or the effective date of such subdivision,
combination or reclassification. Such adjustment shall be made successively
whenever any event listed above shall occur. If a dividend is declared and such
dividend is not paid, the Purchase Price shall again be adjusted to be the
Purchase Price in effect immediately prior to such record date (giving effect to
all adjustments that otherwise would be required to be made pursuant to this
Section 3 from and after such record date).

                  (b) ISSUANCE OF RIGHTS TO PURCHASE COMMON STOCK BELOW CURRENT
MARKET PRICE OR DILUTION PRICE. If the Company shall, at any time or from time
to time, fix a record date for the issuance of rights, options or warrants to
all holders of Common Stock entitling them to subscribe for or purchase Common
Stock, or securities convertible into Common Stock at a price per share of
Common Stock or having a conversion price per share of Common Stock if a
security is convertible into Common Stock (determined in either such case by
dividing (x) the total consideration payable to the Company upon exercise,
conversion or exchange of such rights, options, warrants or other securities
convertible into Common Stock by (y) the total number of shares of Common Stock
covered by such rights, options, warrants or other securities convertible into
Common Stock) which is lower than either the Current Market Price per share of
Common Stock on such record date (or, if an ex-dividend date has been
established for such record date, on the day next preceding such ex-dividend
date) or the Dilution Price, THEN, the Purchase Price shall be reduced to the
price determined by multiplying the Purchase Price in effect immediately prior
to such record date by a fraction, the numerator of which shall be the sum of
the number of shares of Common Stock outstanding on such record date plus the
number of additional shares of Common Stock which the aggregate offering price
of the total number of shares of Common Stock so to be offered (or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at the Applicable Price and the denominator of which shall be the
number of shares of Common Stock outstanding on such record date plus the number
of additional shares of Common Stock to be offered for subscription or purchase
(or into which the convertible securities so to be offered are initially
convertible). In case such price for subscription or purchase may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be determined

                                       5
<Page>

in good faith by the Board of Directors of the Company. Any such adjustment
shall become effective immediately after the record date for such rights or
warrants. Such adjustment shall be made successively whenever such a record date
is fixed. If such rights, options or warrants are not so issued, the Purchase
Price shall be adjusted to the Purchase Price that otherwise would be in effect
but for the fact such record date was fixed (giving effect to all adjustments
that otherwise would be required to be made pursuant to this Section 3 from and
after such record date).

                  (c) CERTAIN DISTRIBUTIONS. If the Company shall, at any time
or from time to time, fix a record date for the distribution to all holders of
Common Stock (including any such distribution made in connection with a
consolidation or merger in which the Company is the continuing corporation) of
evidences of indebtedness, assets or other property (other than regularly
scheduled cash dividends or cash distributions payable out of consolidated
earnings or earned surplus or dividends payable in capital stock for which
adjustment is made under Subsection 3(a)) or subscription rights, options or
warrants (excluding those referred to in Subsection 3(b)), THEN the Purchase
Price shall be reduced to the price determined by multiplying the Purchase Price
in effect immediately prior to such record date by a fraction (which shall in no
event be less than zero), the numerator of which shall be the Current Market
Price per share of Common Stock on such record date (or, if an ex-dividend date
has been established for such record date, on the next day preceding such
ex-dividend date), less the fair market value (as determined in good faith by
the Board of Directors of the Company) of the portion of the assets, evidences
of indebtedness, other property, subscription rights or warrants so to be
distributed applicable to one share of Common Stock and the denominator of which
shall be such Current Market Price per share of Common Stock. Any such
adjustment shall become effective immediately after the record date for such
distribution. Such adjustments shall be made successively whenever such a record
date is fixed. In the event that such distribution is not so made, the Purchase
Price shall be adjusted to the Purchase Price in effect immediately prior to
such record date (giving effect to all adjustments that otherwise would be
required to be made pursuant to this Section 3 from and after such record date).

                  (d) ISSUANCE OF COMMON STOCK BELOW CURRENT MARKET PRICE OR
DILUTION PRICE.

                           (i) If the Company shall, at any time and from time
to time, after the date hereof, directly or indirectly, sell or issue shares of
Common Stock (regardless of whether originally issued or from the Company's
treasury), or rights, options, warrants or convertible or exchangeable
securities containing the right to subscribe for or purchase shares of Common
Stock) at a price per share of Common Stock (determined, in the case of rights,
options, warrants or convertible or exchangeable securities, by dividing (x) the
total consideration received or receivable by the Company in consideration of
the sale or issuance of such rights, options, warrants or convertible or
exchangeable securities, plus the total consideration payable to the Company
upon exercise or conversion or exchange thereof, by (y) the total number of
shares of Common Stock covered by such rights, options, warrants or convertible
or exchangeable securities) which is lower than either the Current Market Price
per share of Common Stock or the Dilution Price immediately prior to such sale
or issuance, then, subject to clause 3(d)(ii), the Purchase Price shall be
reduced to a price determined by multiplying the Purchase Price in effect
immediately prior thereto by a fraction, the numerator of which shall be the sum
of the number of shares of Common Stock outstanding

                                       6
<Page>

immediately prior to such sale or issuance plus the number of shares of Common
Stock which the aggregate consideration received (determined as provided below)
for such sale or issuance would purchase at the Applicable Price and the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately after such sale or issuance. Such adjustment shall be
made successively whenever such sale or issuance is made. For the purposes of
such adjustments, the shares of Common Stock which the holder of any such
rights, options, warrants, or convertible or exchangeable securities shall be
entitled to subscribe for or purchase shall be deemed to be issued and
outstanding as of the date of such sale or issuance and the consideration
"received" by the Company therefor shall be deemed to be the consideration
actually received or receivable by the Company (plus any underwriting discounts
or commissions in connection therewith) for such rights, options, warrants or
convertible or exchangeable securities, plus the consideration stated in such
rights, options, warrants or convertible or exchangeable securities to be
payable to the Company for the shares of Common Stock covered thereby. If the
Company shall sell or issue shares of Common Stock for a consideration
consisting, in whole or in part, of property other than cash or its equivalent,
then in determining the "price per share of Common Stock" and the
"consideration" received or receivable by or payable to the Company for purposes
of the first sentence and the immediately preceding sentence of this Subsection
3(d), the fair value of such property shall be determined in good faith by the
Board of Directors of the Company. The determination of whether any adjustment
is required under this Subsection 3(d) by reason of the sale and issuance of
rights, options, warrants or convertible or exchangeable securities and the
amount of such adjustment, if any, shall be made only at the time of such
issuance or sale and not at the subsequent time of issuance of shares of Common
Stock upon the exercise of such rights to subscribe or purchase.

                           (ii) No adjustment shall be made to the Purchase
Price pursuant to clause 3(d)(i) in connection with the issuance of (A) shares
issued in any of the transactions described in Subsections 3(a), (b) and (c)
hereof; or (B) shares issued upon exercise of this Warrant.

                           (iii) Notwithstanding any provision in Section 3 to
the contrary and without limitation to any other provision contained in Section
3, in the event any securities of the Company (other than this Warrant),
including, without limitation, those securities set forth as exceptions in
Subsection 3(d)(ii) (for purposes of this Subsection, collectively, the "SUBJECT
SECURITIES"), are amended or otherwise modified by operation of its terms or
otherwise (including, without limitation, by operation of such Subject
Securities' anti-dilution provisions) in any manner whatsoever that results in
(i) the reduction of the exercise, conversion or exchange price of such Subject
Securities payable upon the exercise for, or conversion or exchange into, Common
Stock or other securities exercisable for, or convertible or exchangeable into,
Common Stock and/or (ii) such Subject Securities becoming exercisable for, or
convertible or exchangeable into (A) more shares or dollar amount of such
Subject Securities which are, in turn exercisable for, or convertible or
exchangeable into, Common Stock, or (B) more shares of Common Stock, THEN such
amendment or modification shall be treated for purposes of Section 3 as if the
Subject Securities which have been amended or modified have been terminated and
new securities have been issued with the amended or modified terms. The Company
shall make all necessary adjustments (including successive adjustments if
required) to the Purchase Price in accordance with Section 3, but in no event
shall the Purchase Price be greater than it was immediately prior to the
application of this Subsection to the transaction in question. On the expiration
or termination of any such amended or modified Subject Securities for

                                       7
<Page>

which adjustment has been made pursuant to the operation of the provisions of
this Subsection under Section 3(b) or 3(d), as the case may be, without such
Subject Securities having been exercised, converted or exchanged in full
pursuant to their terms, the adjusted Purchase Price shall be appropriately
readjusted in the manner specified in such Section.

                  (e) ADJUSTMENTS TO OTHER SHARES. In the event that at any
time, as a result of an adjustment made pursuant to Subsection 3(a), the Holder
shall become entitled to receive, upon exercise of this Warrant, any shares of
capital stock of the Company other than shares of Common Stock, the number of
such other shares so receivable upon exercise of this Warrant shall be subject
to adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the shares of Common Stock
contained in Subsections 3(a), (b), (c) and (d), inclusive, and the provisions
of Sections 2, 5, 6 and 7 with respect to the shares of Common Stock shall apply
on like terms to any such other shares.

                  (f) ADJUSTMENT OF NUMBER OF SHARES ISSUABLE UPON EXERCISE.
Upon each adjustment of the Purchase Price as a result of the calculations made
in Subsections 3(a), (b), (c) or (d), this Warrant shall thereafter evidence the
right to receive, at the adjusted Purchase Price, that number of shares of
Common Stock (calculated to the nearest one-hundredth) obtained by dividing (x)
the product of the aggregate number of shares of Common Stock covered by this
Warrant immediately prior to such adjustment and the Purchase Price in effect
immediately prior to such adjustment of the Purchase Price by (y) the Purchase
Price in effect immediately after such adjustment of the Purchase Price.

                  (g) REORGANIZATION, RECLASSIFICATION, MERGER AND SALE OF
ASSETS. If there occurs any capital reorganization or any reclassification of
the Common Stock of the Company, the consolidation or merger of the Company with
or into another Person (other than a merger or consolidation of the Company in
which the Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, THEN the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Common Stock
then deliverable upon the exercise of this Warrant as if this Warrant had been
exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance; and, in any such case, appropriate
adjustments (as determined in good faith by the Board of Directors of the
Company) shall be made to assure that the provisions hereof (including
provisions with respect to changes in, and other adjustments of, the Purchase
Price) shall thereafter be applicable, as nearly as reasonably may be
practicable, in relation to any securities or other assets thereafter
deliverable upon exercise of this Warrant.

         4. CERTIFICATE AS TO ADJUSTMENTS. Whenever the number of shares of
Common Stock issuable, or the securities or other property deliverable, upon the
exercise of this Warrant shall be adjusted pursuant to the provisions hereof,
the Company shall promptly give written notice thereof

                                       8
<Page>

to the Holder, in accordance with Section 13, in the form of a certificate
signed by the Chairman of the Board, President or one of the Vice Presidents of
the Company, and by the Chief Financial Officer, Treasurer or one of the
Assistant Treasurers of the Company, stating the adjusted number of shares of
Common Stock issuable, or the securities or other property deliverable, upon
exercise of the Warrant and setting forth in reasonable detail the method of
calculation and the facts requiring such adjustment and upon which such
calculation is based. Each adjustment shall remain in effect until a subsequent
adjustment is required.

         5. FRACTIONAL SHARES. Notwithstanding an adjustment of this Warrant to
the contrary, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence
fractional shares. In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the greater of the Current
Market Price of a share of Common Stock on the Exercise Date and the Dilution
Price.

         6. NOTICE OF PROPOSED ACTIONS. In case the Company shall propose at any
time or from time to time (a) to declare or pay any dividend payable in stock of
any class to the holders of Common Stock or to make any other distribution to
the holders of Common Stock (other than a regularly scheduled cash dividend),
(b) to offer to the holders of Common Stock rights or warrants to subscribe for
or to purchase any additional shares of Common Stock or shares of stock of any
class or any other securities, rights or options, (c) to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, (e) to
effect the liquidation, dissolution or winding up of the Company, or (f) to take
any other action that would require a vote of the Company's stockholders, then,
in each such case, the Company shall give to the Holder, in accordance with
Section 13, a written notice of such proposed action, which shall specify (i)
the record date for the purposes of such stock dividend, distribution of rights
or warrants or vote of the stockholders of the Company, or if a record is not to
be taken, the date as of which the holders of shares of Common Stock of record
to be entitled to such dividend, distribution of rights or warrants, or vote is
to be determined, or (ii) the date on which such reclassification,
consolidation, merger, sale, transfer, disposition, liquidation, dissolution or
winding up is expected to become effective, and such notice shall be so given as
promptly as possible but in any event at least ten (10) Business Days prior to
the applicable record, determination or effective date specified in such notice.

         7. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, but will at all times in good faith assist in the carrying out
of all such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Holder of this Warrant against
dilution or other impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of stock
receivable on the exercise of this Warrant above the amount payable therefor on
such exercise, (b) will at all times reserve and keep available the maximum
number of its authorized shares of Common Stock, free from all preemptive rights
therein, which will be sufficient to permit the full

exercise of this Warrant, and (c) will take all such action as may be necessary
or appropriate in order that all shares of Common Stock as may be issued

validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

         8. REPLACEMENT OF WARRANTS. On receipt by the Company of an affidavit
of an authorized representative of the Holder stating the circumstances of the
loss, theft, destruction or mutilation of this Warrant (and in the case of any
such mutilation, on surrender and cancellation of such Warrant), the Company at
its expense will promptly execute and deliver, in lieu thereof, a new Warrant of
like tenor which shall be exercisable for a like number of shares of Common
Stock. If required by the Company, such Holder must provide an indemnity bond or
other indemnity sufficient in the judgment of the Company to protect the Company
from any loss which it may suffer if a lost, stolen or destroyed Warrant is
replaced.

         9. RESTRICTIONS ON TRANSFER.

                  (a) The term "HOLDER" as used herein shall also include any
transferee of this Warrant whose name has been recorded by the Company in the
Warrant Register (as hereinafter defined). Each transferee of this Warrant or
the Common Stock issuable upon the exercise hereof acknowledges that this
Warrant or the Common Stock issuable upon the exercise hereof has not been
registered under the Securities Act and may be transferred only pursuant to an
effective registration under the Securities Act or pursuant to an applicable
exemption from the registration requirements of the Securities Act.

                  (b) With respect to a transfer that should occur prior to the
time that the Warrant or the Common Stock issuable upon the exercise thereof is
registered under the Securities Act, such Holder shall request an opinion of
counsel (which shall be rendered by counsel reasonably acceptable to the
Company) that the proposed transfer may be effected without registration or
qualification under any Federal or state securities or blue sky law. Counsel
shall, as promptly as practicable, notify the Company and the Holder of such
opinion and of the terms and conditions, if any, to be observed in such
transfer, whereupon the Holder shall be entitled to transfer this Warrant or
such shares of Common Stock (or portion thereof), subject to any other
provisions and limitations of this Warrant. In the event this Warrant shall be
exercised as an incident to such transfer, such exercise shall relate back and
for all purposes of this Warrant be deemed to have occurred as of the date of
such notice regardless of delays incurred by reason of the provisions of this
Section 9 which may result in the actual exercise on any later date.

                  (c) The Company shall maintain a register (the "WARRANT
REGISTER") in its principal office for the purpose of registering the Warrant
and any transfer thereof, which register shall reflect and identify, at all
times, the ownership of any interest in the Warrant. Upon the issuance of this
Warrant, the Company shall record the name of the initial purchaser of this
Warrant in the Warrant Register as the first Holder. Upon surrender for
registration of transfer or exchange of this Warrant together with a properly
executed Form of Assignment attached hereto as EXHIBIT B at the principal office
of the Company, the Company shall, at its expense, execute and deliver one or
more

                                       10

new Warrants of like tenor which shall be exercisable in the aggregate for the
Total Percentage of Warrant Shares, registered in the name of the Holder or a
transferee or transferees.

                  This Warrant may be transferred or assigned, in whole or in
part, by the Holder at any time without the consent of the Company.

         10. NO RIGHTS OR LIABILITY AS A STOCKHOLDER. This Warrant does not
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company. No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Common Stock, and no enumeration herein of the
rights or privileges of the Holder shall give rise to any liability of such
Holder as a stockholder of the Company.

         11. CHARGES, TAXES AND EXPENSES. Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the Holder hereof for any issue or transfer tax, or other incidental expense, in
respect of the issuance or delivery of such certificates or the securities
represented thereby, all of which taxes and expenses shall be paid by the
Company.

         12. AMENDMENT OR WAIVER. This Warrant and any term hereof may be
amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

restrictions of record.

         Lessor further covenants to keep the Lessee in the quiet possession of
the premises during the aforesaid term, provided Lessee shall comply with all of
the provisions of this lease.

         5A. USE OF PREMISES: Except as otherwise provided in the Lease, Lessee
shall have the right to use the Demised Premises for any and all lawful
purposes; subject, however, to the zoning regulations and restrictive covenants

any federal, state or local laws, ordinances or regulations, now or hereafter in
effect, relating to environmental matters, industrial hygiene, occupational
health or hazardous materials (hereafter "Environmental Laws"). Lessee shall not

state or federal standard) amount of hazardous substances onto the Demised
Premises without the express written consent of the Lessor. Lessee shall only
handle, store or use Hazardous Substances in the minimum quantities practicable
for its operations. The foregoing restrictions shall not in any way be construed
to limit or affect Lessee's obligation under this Lease to comply with
applicable law or indemnify Lessor against any harm or damage caused by such
substances.

         (b) No spill, deposit, emission, leakage or other release of Hazardous
Substance into the soils, groundwater, surface waters, buildings or structures
shall be deemed "ordinary wear and tear", and Lessee shall be responsible to
promptly and, to the extent required by applicable law, cleanup any such release
as shall occur at the Premises during the term of the Lease and shall surrender
the Premises free of any significant (meaning in excess of amounts allowed by
applicable law) contamination or damage caused by such occurrences during the
term of this Lease. Lessee further covenants that Lessee will be responsible for
the cost of any environmental contamination including but not limited to
inspection by reputable firms, any cleanup or other procedures to eradicate
hazardous materials and any follow up inspection by qualified firms.

<Page>

                  i) any and all enforcement, cleanup, removal, mitigation or
other governmental or regulatory actions instituted or threatened pursuant to
any Environmental Laws affecting the Premises;

                  ii) any and all claims made or threatened by any third party
relating to damage, contribution, cost recovery, compensation, loss or injury
resulting from any Hazardous Substances allegedly arising from the Premises;

                  iii) Lessee's discovery of any occurrence or condition on the
Premises which could subject the premises to any liabilities or any restriction
on ownership, occupancy, transferability or use of the Premises under the
Environmental Laws.

         (d) Lessee shall permit Lessor and his agents to enter into and upon
the Premises, without notice, at all reasonable times for the purpose of
inspecting the Premises and all activities thereon, including without
limitation, activities related to Hazardous Substances.

         5C. LESSOR WARRANTY:

         Lessor agrees to indemnify and hold harmless Lessee from any and all
claims, damages, fines, judgments, penalties, costs, liabilities, or losses,
including reasonable litigation expenses, whether arising during or after the
term of this lease, relating to any Hazardous Substance not introduced into or
used on the premises by Lessee (whether before or during the term of this Lease)
or, to the extent Lessee can otherwise show, any Hazardous Substance which does
not result from Lessee's lease or use of the Premises. Lessee agrees to provide
prompt notice of any such claim to Lessor and to tender the defense, at Lessor's
sole option, of any such claim to Lessor.

         6. RENTAL:

         A. INITIAL TERM: Lessee covenants and agrees to pay Lessor as rent for

payable May 1, 2001 and a like payment on the first day of each month thereafter
through April 1, 2008. Rent shall increase each Lease Year by one and one half

notice in writing of its election to exercise the Option at least nine (9)
months prior to the termination of the initial term of this Lease.

         7. TENANT IMPROVEMENTS: Lessor shall provide $600,000 (the "Allowance")

particularly on EXHIBIT

                                       3
<Page>

C attached hereto and incorporated herein by reference (the "Improvements").
Lessor shall complete the Improvements on or before June, 2001. In the event the
total cost of the Improvements exceeds the Allowance, Lessee shall pay for such
overage. In addition, Lessor shall provide furniture systems for the Premises in
an amount not to exceed $275,000 (the "Furniture Systems"), such systems to be

         8. ENTRY BY LESSOR: Lessor, through its agents or representatives,
reserves the right to inspect said premises from time to time and to make
repairs that Lessor deems necessary, provided such inspections and repairs will
in no way curtail or affect the operations of Lessee, and Lessor agrees to
subject itself and its agents and representatives to those reasonable measures
deemed necessary to Lessee to protect its security. Lessor and Lessor shall have
the further right to show the Demised Premises to prospective lenders, tenants,
and purchasers, at any time during business hours, with 24 hour notice to
Lessee.

         9. UTILITIES AND SERVICES: Lessee shall pay, when due, all bills for

business, at a location to be agreed upon by the Lessor, provided said sign does
no damage to the building or improvements on the premises. The design of such
sign and its location, must be approved by the Lessor, which approval shall not
be unreasonably withheld.

         11. DAMAGE OR LOSS OF PROPERTY: Lessor shall not be liable for the loss
of any property of the Lessee from the Demised Premises or for any damage to any

         12. INDEMNIFICATION BY LESSEE: Lessor shall not be liable to Lessee or
Lessee's employees, agents, patrons or visitors, or to any other person
whomsoever, for any injury to persons or damage to property on or about the

of Lessee, its agents, servants or employees, or any other persons entering upon
the Demised Premises, or caused by the buildings or improvements located on the
real estate on which the Demised Premises are located becoming out of repair, or
caused by any prior or future leakage of gas, oil, hazardous substances, water
or steam, or by electricity emanating from the real estate or due to any cause
whatsoever, and Lessee hereby covenants and agrees that it will at all times
indemnify and hold safe and harmless the Lessor and Lessor's agents and
employees from any loss, liability, claims, suits, costs, expenses, including,
without limitation attorneys' fees and damages, both real and alleged, arising
out of any such damage or injury; except injury to persons or damage to
property, the sole cause of which is the negligence of the Lessor or the failure
of the Lessor to repair any part of the Demised Premises which Lessor is
obligated to repair and maintain hereunder within a reasonable time after the
receipt of written notice from Lessee of needed repairs. Lessee shall procure
and maintain through the term of this sublease a policy or policies of
insurance, at its sole cost and expense, insuring against all claims, demands,
or actions arising out of or in connection with: (i) Demised Premises; (ii) the
condition of the Demised Premises; (iii) Lessee's

                                       4
<Page>

operations in and maintenance and use of the Demised Premises; and (iv) Lessee's
ability or policies to be in the amount of not less than $3,000,000 per
occurrence in respect to injury to persons (including death) and in the amount
of not less than $1,000,000 per occurrence in respect of property damage or
destruction, including loss of use thereof All such policies shall be procured
by Lessee from responsible insurance companies. Certificate of Insurance
evidencing such coverage shall be delivered to Lessor prior to the commencement
date of this Lease. Not less than fifteen days prior to the expiration date of
any such policy, Certificates of Insurance evidencing renewal of insurance
policies for such coverage shall be delivered to Lessor. Such Certificates of
Insurance shall further provide that not less than thirty days' written notice
shall be given to Lessor before such policy may be canceled or changed to reduce
insurance provided thereby.

         13. AD-VALOREM TAXES: Lessor shall pay all ad valorem taxes and special
assessment taxes assessed or charged against or upon the Demised Premises,
including taxes and assessments on or against the land and building, but Lessee
shall pay such taxes or assessments against its personal property located in the
leased building.

         Notwithstanding anything herein to the contrary, if the Demised
Premises cannot be maintained as a "Project" as that term is defined in Code of
Alabama, 1975, Sections 11-54-80, et seq., then Lessee shall be obligated to pay
to the Lessor on December 31 of every year during the term hereof an amount of
money equal to the ad valorem taxes payable for the Demised Premises for said
year.

         14. FIRE INSURANCE ON CONTENTS: Lessee agrees that it will carry fire
insurance with extended coverage on the contents of personal property to be
located within the Demised Premises.

         15. FIRE AND CASUALTY DAMAGE:

         A. Lessor agrees, at its expense, to maintain insurance covering the
building in an amount not less than eighty percent (80%) (or such greater
percentage as may be necessary to comply with the provisions of any co-insurance
clauses of the policy) of the replacement cost thereof, insuring against the
perils of Fire, Lightning, Extending Coverage, Endorsement to insure against all
other Risks of Direct Physical Loss, such coverages and endorsements to be as
defined, provided and limited in the standard bureau forms prescribed by the
insurance regulatory authority for the State of Alabama for use by insurance
companies admitted in Alabama for the writing of such insurance of risks located
without such State. Subject to the provisions of subparagraph B and D below,
such insurance shall be for the sole benefit of Lessor and under its sole
control.

         B. If the building should be damaged by fire, tornado, or other
casualty, Lessee shall give immediate written notice thereof to Lessor.

         C. If the building should be destroyed by fire, tornado, or other
casualty, or if it should be so damaged thereby that rebuilding or repairs
cannot in Lessor's estimation be completed with two hundred (200) days after the
date upon which Lessor is notified by Lessee of

                                       5
<Page>

such damage, this sublease shall terminate and the rent shall be abated during
the unexpired portion of this sublease, effective upon the date of the
occurrence of such damage.

         D. If the building should be damaged by any peril covered by the
insurance to be provided by Lessor under subparagraph A above, but only to such
extent that rebuilding or repairs can in Lessor's estimation be completed within
two hundred (200) days after the date upon which Lessor is notified by Lessee of
such damage, this Lease shall not terminate, and Lessor shall at its sole cost
and expense thereupon proceed with reasonable diligence to rebuild and repair
the Building to substantially the condition in which it existed prior to such
damage; except that Lessor shall not be required to rebuild, repair or replace
any part of the partitions, fixtures, additions and other improvements which may
have been placed in, or about the Demised Premises by Lessee. If the Demised
Premises are untenantable in whole or in part following such damage, the rent
payable hereunder during the period in which they are untenantable shall be
reduced to such extent as may be fair and reasonable under all of the
circumstances. In the event that Lessor should fail to complete such repairs or
rebuilding within two hundred (200) days after the date upon which Lessor is
notified by Lessee of such damage, Lessee may at its option terminate this Lease
by delivering written notice of termination to Lessor as Lessee's exclusive
remedy, whereupon all rights and obligations hereunder shall cease and
terminate.

         E. Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed or trust covering the
Demised Premises requires that the insurance proceeds be applied to such
indebtedness, then Lessor shall have the right to terminate this Lease by
delivering written notice of termination to Lessee within fifteen (15) days
after such requirements are made by any such holder, whereupon all rights and
obligations hereunder shall cease and terminate.

         F. Anything in this Lease to the contrary notwithstanding, Lessor and
Lessee hereby waive and release each other of and from any and all rights of
recovery, claim, action or cause of action, against each other, their agents,
officers and employees, for any loss or damage that may occur to the Demised
Premises, improvements to the building, or personal property (building contents
within the building) by reason of fire or the elements regardless of cause or
origin, including negligence of Lessor or Lessee and their agents, officers and
employees. Because this subparagraph will preclude the assignment of any claim
mentioned in it by way of subrogation (or otherwise) to an insurance company (or
any other person), each party to this lease and subsequent Lease agrees
immediately to give each insurance company which has issued to it policies of
fire and extended coverage insurance, written notice of the terms of the mutual
waivers contained in this subparagraph, and to have the insurance policies
properly endorsed, if necessary, to prevent the invalidation of the insurance
coverages by reason of the mutual waivers contained in this subparagraph.

         16. WAIVER OF SUBROGATION: Lessor shall not be liable for any damage to
fixtures, equipment or other property of Lessee caused by fire or other
insurable hazards, regardless of the nature or cause, and Lessee expressly
releases Lessor from all liability for such damage. Lessee shall not be liable
for any damage to the Demised Premises caused by fire or other insurable hazards
or to any portion of such premises, regardless of the nature or cause of

                                       6
<Page>

the fire or other hazards, and Lessor hereby expressly releases Lessee from all
liability for such damage.

         17. ALTERATIONS: Lessee may make non-structural alterations to the
Demised Premises at its expense, except that written approval must first be
obtained from Lessor, which approval will not be unreasonably withheld. All
alterations must be approved by the Inspection Department of the City of
Huntsville and shall become a part of the Demised Premises and be the property
of Lessor, unless otherwise agreed to in writing by Lessor prior to the time
that said alterations are made. Lessee agrees to remove the non-structural
alterations at the request of the Lessor.

         Lessor shall have the right, but not the obligation, to make such
alterations and modifications to the building or buildings in which the Demised
Premises are located, and/or all common areas surrounding the same, as Lessor
may elect, consistent with sound engineering and aesthetic landscaping
principles.

         18. CONDEMNATION: Should the entire Demised Premises, or such portion
of the Demised Premises as would substantially interfere with the operation of
the business of the Lessee, be taken by the public authority under the power of
eminent domain, or like power, and should the parties hereto fail to agree upon
a new rental basis for the remaining portion, then this Lease shall terminate
effective as of the date possession thereof shall be required to be delivered
pursuant to the final order, or judgment or decree entered in the proceedings in
exercise of such power. All damages awarded for the taking of said premises or
any part thereof, shall be payable in the full amount thereof to and the name
shall be the property of the Lessor, including, but not limited to, any sum paid
or payable as compensation for loss of value of the leasehold, and Lessee shall
be entitled only to that portion of the award expressly stated to have been made
to it for a loss of business and the loss of value and cost of removal or stock,
equipment and furniture owned and removable by the Lessee without damaging the
building.

         19. ASSIGNMENT OR SUBLETTING: Lessee shall have the right to assign or
sublease all or any part of the premises with the written approval of Lessor,
which approval will not be unreasonably withheld.

         20. DEFAULT: In the event Lessee fails to pay any installment of rental
as it becomes due, Lessor may, after first giving ten (10) days' notice in
writing to Lessee of such default, terminate this lease and re-enter the leased
premises by summary proceedings or otherwise expelling Lessee and removing all
property therefrom.

         With respect to any other violation or breach of this agreement other
than the payment of rental, Lessor shall give to Lessee thirty (30) days' notice
in writing of such violation or breach and upon the failure of Lessee to correct
such violation before the expiration of such thirty (30) days, Lessor shall have
the right of termination and re-entry as hereinabove provided.

         In the event Lessee files a voluntary petition in bankruptcy or has an
involuntary petition in bankruptcy filed against it and the petition is not
dismissed within thirty (30) days after the filing thereof, or if Lessee becomes
a debtor in any plan or reorganization as allowed by the laws of the United
States or federal court, or if Lessee makes an assignment for the benefit of

                                       7
<Page>

creditors, then, in any one of such events, Lessor may, at its option, declare
the term of this Lease at an end and in any one of such events above named,
Lessee shall thereafter have no right of possession or interest in or to the
leased premises.

         In the event of the employment of an attorney by Lessor on account of
the violation of, or breach of, or in an endeavor to enforce any of the terms,
provisions, or conditions of this Lease, and Lessor prevails, Lessee agrees to
pay to Lessor a reasonable attorney's fee for the services of said attorney.

         21. REMEDIES:

         A. Upon the occurrence of any of such events of default described in
Paragraph 20 hereof, Lessor shall have the option to pursue any one or more of
the following remedies without any notice or demand whatsoever:

         (i) To terminate this Lease, in which event Lessee shall immediately
surrender the Demised Premises to Lessor and if Lessee fails to do so, Lessor
may, without prejudice to any other remedy which it may have for possession or
arrearages in rent, enter upon and take possession of the Demised Premises and
expel or remove Lessee and any other person who may be occupying the Demised
Premises or any part thereof, without being liable for prosecution of any claim
of damages therefore,

         (ii) Enter upon the Demised Premises, without being liable for
prosecution of any claim for damages therefore, and do whatever Lessee is
obligated to do under the terms of this Lease; and Lessee agrees to reimburse
Lessor on demand for any expenses which Lessor may incur in thus effecting
compliance with Lessee's obligation under this Lease, and Lessee further agrees
that Lessor shall not be liable for any damages resulting to the Lessee from
such action, whether caused by the negligence of Lessor or otherwise;

         B. In the event Lessor may elect to regain possession of the Demised
Premises by a forcible detainer proceeding, Lessee hereby specifically waives
any statutory notice which may be required prior to such proceeding, and agrees
that Lessor's execution of this Lease is, in part, consideration of this waiver.

         C. Exercise by Lessor of any one or more remedies hereunder granted or
otherwise available shall not be deemed to be an acceptance of surrender of the
Demised Premises by Lessee, whether by agreement or by operation of law, it
being understood that such surrender can be effected only by the written
agreement of Lessor and Lessee. No removal or other exercise of dominion by
Lessor over the property of Lessee or others at the Demised Premises shall be
deemed unauthorized or constitute a conversion, Lessee hereby consenting, after
any event of default, to the aforesaid exercise of dominion over Lessee's
property within the Demised Premises. All claims for damages by reason of such
re-entry and/or repossession and/or alteration of locks or other security
devises are hereby waived, as are all claims for damages by reason of any
distress warrant, forcible detainer proceedings, sequestration proceedings or
other legal process. Lessee agrees that any reentry by Lessor may be pursuant to
judgment obtained in forcible detainer proceedings or other legal proceedings or
without the necessity of any legal proceedings, as Lessor may elect, and Lessor
shall not be liable in trespass or otherwise.

                                       8
<Page>

         D. In the event Lessor elects to terminate the Lease by reason of any
event of default, the notwithstanding such termination, Lessee shall be liable
for and shall pay to Lessor, at the address specified for notice to Lessor
herein, the sum of all rental and other indebtedness accrued to date of such
termination, plus, as damages, an amount equal to the greater of (i) the total
rental hereunder for the remaining portion of the Lease term (had such term not
been terminated by Lessor prior to the date of expiration stated in Paragraph
2), and (ii) the then present value of the then fair rental value of the Demised
Premises for such period.

         E. In the event that Lessor elects to repossess the Demised Premises
without terminating this Lease, or in the event Lessor elects to terminate this
Lease, then Lessee, at Lessor's option, shall be liable for and shall pay to
Lessor, at the address specified for notice to Lessor herein, all rental and
other indebtedness accrued to the date of such repossession, plus rental
required to be paid by Lessee to Lessor during the remainder of this Lease term
until the date of expiration of the term, as stated in Paragraph 2, diminished
by any net sum thereafter received by Lessor through reletting the Demised
Premises during said period (after deducting expenses incurred by Lessor as
provided in subparagraph F below). In no event shall Lessee be entitled to any
excess of any rental obtained by reletting over and above the rental herein
reserved. Actions to collect amounts due by Lessee to Lessor under this
subparagraph may be brought from time to time, on one or more occasions, without
the necessity of Lessor's waiting until expiration of the Lease term.

         F. In case of any event of default or breach of Lease, or threatened or
anticipatory breach or default, Lessee shall also be liable for and shall pay to
Lessor, at the address specified for notice to Lessor herein, in addition to any
sum provided to be paid above, brokers' fees incurred by Lessor in connection
with reletting the whole or any part of the Demised Premises; the costs of
removing and storing Lessee's or other occupant's property; the costs of
repairing, altering, remodeling or otherwise putting the Demised Premises into
condition acceptable to a new tenant or tenants; and all reasonable expense
incurred by Lessor in enforcing or defending Lessor's rights and/or remedies
including reasonable attorney's fee, whether suit is actually filed or not.

         G. In the event of termination or repossession of the Demised Premises
for an event of default, Lessor shall not have any obligation to relet or to
attempt to relet the Demised Premises, or any portion thereof, to collect rental
after reletting; and in the event of reletting, Lessor may relet the whole or
any portion thereof, or to collect rental after reletting; and in the event of
reletting, Lessor may relet the whole or any portion of the Demised Premises for
any period to any tenant and for any use and purpose.

         H. If Lessee should fail to make any payment or cure any default
hereunder within the term herein permitted, Lessor, without being under any
obligation to do so and without thereby waiving such default, may make such
payment and/or remedy such other default for the account of Lessee (and enter
the Demised Premises for such purpose), and thereupon Lessee shall be obligated
to, and hereby agrees, to pay Lessor, upon demand, all costs, expenses, and
disbursements (including reasonable attorney's fees) incurred by Lessor in
taking such remedial action.

                                       9
<Page>

         I. In the event of any default by Lessor, Lessee's exclusive remedy
shall be an action for damages (Lessee hereby waiving the benefit of any laws
granting it a lien upon the property of Lessor and/or upon rent due Lessor), but
prior to any such action Lessee will give Lessor written notice specifying such
default with particularity, and Lessor shall thereupon have thirty (30) days in
which to cure any such default. Unless and until Lessor fails to so cure any
default upon such notice, Lessee shall not have any remedy or cause of action by
reason thereof. All obligations of Lessor hereunder will be construed as
covenants, not conditions; and all such obligations will be binding upon Lessor
only during the period of its possession of the Real Estate, and in the event of
the transfer by such owner of its interest in the Real Estate, such transferor
owner shall thereupon be released and discharged from all covenants and
obligations of the Lessor thereafter accruing, but such covenants and obligation
shall be binding during the lease term upon each new owner for the duration of
such owner's ownership. Notwithstanding any other provision of this lease,
Lessee agrees to look solely to the equity or interest then owned by Lessor in
the Real Estate and in no event shall any deficiency judgment or any money
judgment of any kind be sought or obtained against any party Lessor for breach
of any of the covenants of Lessor hereunder or for any of the indemnifications
by Lessor arising under this Lease.

         22. PARKING: Lessor will provide parking spaces for Lessee in the
parking lots as provided in Exhibit C attached hereto. These parking spaces will
be exclusively for the use of the Lessee, its agents, employees, customers, and
invitees.

         23. MAINTENANCE AND REPAIRS: Lessee shall maintain, in good condition,
all mechanical equipment attached to the Demised Premises; provided, however,
that Lessor shall at its expense repair or replace all heating, air-conditioning
or water cooling units (including compressors and combustion chambers) and
cafeteria equipment which, although properly maintained, have failed because of
age or other faults not caused by the Lessor; and further provided that if such
units are not properly maintained or are otherwised damaged by Lessee or its
agents or employees, such repair or replacement shall be the responsibility of
the Lessee, at its expense.

         Lessee shall be responsible, at its expense, for all lawn maintenance
for the Demised Premises and the Property.

         Lessor shall maintain and repair, at its expense, the exterior roof of
the Demised Premises.

         Lessee agrees to provide all other maintenance and repairs not herein
specifically mentioned.

         Lessee agrees at the time of vacating the Demised Premises to return
the Demised Premises to the Lessor in the same good condition as when they first
occupied the Demised Premises at the commencement of the lease term.

         24. JANITORIAL SERVICES: Lessee shall provide at its expense all
janitorial services to the Demised Premises.

                                       10

         25. MORTGAGES: Lessee accepts this Lease subject and subordinate to any
mortgage(s) and/or deed(s) of trust now or any time hereafter constituting a
lien or charge upon the premises or the improvements situated thereon; provided,
however, that if the mortgagee, trustee, or holder of any such mortgage or deed
of trust elects to have Lessee's interest in this Lease superior to any such
instrument, then by notice to Lessee from such mortgagee, trustee or holder,
this sublease shall be deemed superior to such lien, whether this Lease was
executed before or after said mortgage or deed of trust. Lessee shall at any
time hereafter, on demand, execute any instruments, releases, or other documents
which may be required by any mortgage for the purpose of subjecting and
subordinating this Lease to the lien of any such mortgage.

         26. NOTICES: All notices to be given by either of the parties shall be
given in writing and by depositing the same in the United States mail, postage
prepaid, certified or registered, return receipt requested, and addressed to the
parties at the following addresses:
