THE WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT (THE
"SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE
"SECURITIES ACT") OR UNDER ANY STATE SECURITIES OR BLUE SKY LAWS ("BLUE SKY
LAWS"). NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER
DISPOSITION OF THIS WARRANT OR THE SECURITIES OR ANY INTEREST THEREIN MAY BE
MADE EXCEPT (a) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT AND ANY APPLICABLE BLUE SKY LAWS OR (b) IF THE COMPANY HAS BEEN
FURNISHED WITH BOTH AN OPINION OF COUNSEL FOR THE HOLDER, WHICH OPINION AND
COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT NO
REGISTRATION IS REQUIRED BECAUSE OF THE AVAILABILITY OF AN EXEMPTION FROM
REGISTRATION UNDER THE SECURITIES ACT AND APPLICABLE BLUE SKY LAWS, AND
ASSURANCES THAT THE TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER
DISPOSITION WILL BE MADE ONLY IN COMPLIANCE WITH THE CONDITIONS OF ANY SUCH
REGISTRATION OR EXEMPTION.

                   WARRANT TO PURCHASE SHARES OF COMMON STOCK
                         OF ACTIVE IQ TECHNOLOGIES, INC.

WARRANT NO. _____                                         Minneapolis, Minnesota
                                                                    May 31, 2002

         This certifies that, for value received, _____________, or [his/its]
successors or assigns (the "Holder") is entitled to purchase from Active IQ
Technologies, Inc. (the "Company") _________________________ (________) fully
paid and nonassessable shares (the "Shares") of the Company's Common Stock, $.01
par value (the "Common Stock"), at an exercise price of $1.25 per share (the
"Exercise Price"), subject to adjustment as herein provided. This Warrant may be
exercised by Holder at any time after the date hereof; provided, however, that,
Holder shall in no event have the right to exercise this Warrant or any portion
thereof later than the five (5) year anniversary of the date hereof, at which
time all of Holder's rights hereunder shall expire.

         This Warrant is subject to the following provisions, terms and
conditions:

         1. Exercise of Warrant. The rights represented by this Warrant may be
exercised by the Holder, in whole or in part (but not as to a fractional share
of Common Stock), by the surrender of this Warrant (properly endorsed, if
required, at the Company's principal office in Minneapolis, Minnesota, or such
other office or agency of the Company as the Company may designate by notice in
writing to the Holder at the address of such Holder appearing on the books of
the Company at any time within the period above named), and upon payment to it
by certified check, bank draft or cash of the purchase price for such Shares.
The Company agrees that the Shares so purchased shall have and are deemed to be
issued to the Holder as the record owner of such Shares as of the close of
business on the date on which this Warrant shall have been surrendered and
payment made for such Shares as aforesaid. Certificates for the Shares of Common
Stock so purchased shall be delivered to the Holder within a reasonable time,
not exceeding ten (10) days, after the rights represented by this Warrant shall
have been so exercised, and, unless this Warrant has expired, a new Warrant
representing the number of Shares, if any, with respect to which this Warrant
shall not then have been exercised shall also be delivered to the Holder within
such time. The Company may require that any such new Warrant or any certificate
for Shares purchased upon the exercise hereof bear a legend substantially
similar to that which is contained on the face of this Warrant.

<PAGE>

         2. Transferability of this Warrant. This Warrant is issued upon the
following terms, to which Holder consents and agrees:

                  (a) Until this Warrant is transferred on the books of the
Company, the Company will treat the Holder of this Warrant registered as such on
the books of the Company as the absolute owner hereof for all purposes without
being affected by any notice to the contrary.

                  (b) This Warrant may not be exercised, and this Warrant and
the Shares underlying this Warrant shall not be transferable, except in
compliance with all applicable state and federal securities laws, regulations
and orders, and with all other applicable laws, regulations and orders.

                  (c) The Warrant may not be transferred, and the Shares
underlying this Warrant may not be transferred, without the Holder obtaining an
opinion of counsel satisfactory in form and substance to the Company's counsel
stating that the proposed transaction will not result in a prohibited
transaction under the Securities Act of 1933, as amended ("Securities Act"), and
applicable Blue Sky laws. By accepting this Warrant, the Holder agrees to act in
accordance with any conditions reasonably imposed on such transfer by such
opinion of counsel.

                  (d) Neither this issuance of this Warrant nor the issuance of
the Shares underlying this Warrant have been registered under the Securities
Act.

         3. Certain Covenants of the Company. The Company covenants and agrees
that all Shares which may be issued upon the exercise of the rights represented
by this Warrant, upon issuance and full payment for the Shares so purchased,
will be duly authorized and issued, fully paid and nonassessable and free from
all taxes, liens and charges with respect to the issue hereof, except those that
may be created by or imposed upon the Holder or its property, and without
limiting the generality of the foregoing, the Company covenants and agrees that
it will from time to time take all such actions as may be requisite to assure
that the par value per share of the Common Stock is at all times equal to or
less than the effective purchase price per share of the Common Stock issuable
pursuant to this Warrant. The Company further covenants and agrees that during
the period within which the rights represented by this Warrant may be exercised,
the Company will at all times have authorized and reserved free of preemptive or
other rights for the exclusive purpose of issue upon exercise of the purchase
rights evidenced by this Warrant, a sufficient number of shares of its Common
Stock to provide for the exercise of the rights represented by this Warrant.

         4. Adjustment of Exercise Price and Number of Shares. The Exercise
Price and number of Shares are subject to the following adjustments:

                  (a) Adjustment of Exercise Price for Stock Dividend, Stock
Split or Stock Combination. In the event that (i) any dividends on any class of
stock of the Company payable in Common Stock or securities convertible into or
exercisable for Common Stock ("Common Stock Equivalents") shall be paid by the
Company, (ii) the Company shall subdivide its then outstanding shares of Common
Stock into a greater number of shares, or (iii) the Company shall combine its
outstanding shares of Common Stock, by reclassification or otherwise, then, in
any such event, the Exercise Price in effect immediately prior to such event
shall (until adjusted again pursuant hereto) be adjusted immediately after such
event to a price (calculated to the nearest full cent) determined by dividing
(a) the number of shares of Common Stock outstanding immediately prior to such
event, multiplied by the then existing Exercise Price, by (b) the total number
of shares of Common Stock outstanding immediately after such event, and the
resulting quotient shall be the adjusted Exercise Price per share. No adjustment
of the Exercise Price shall be made if the amount of such adjustment shall be

<PAGE>

less than $.05 per share, but in such case any adjustment that would otherwise
be required then to be made shall be carried forward and shall be made at the
time and together with the next subsequent adjustment which, together with any
adjustment or adjustments so carried forward, shall amount to not less than $.05
per share.

                  (b) Adjustment of Number of Shares Purchasable on Exercise of
Warrants. Upon each adjustment of the Exercise Price pursuant to this Section,
the Holder shall thereafter (until another such adjustment) be entitled to
purchase at the adjusted Exercise Price the number of shares, calculated to the
nearest full share, obtained by multiplying the number of shares specified in
such Warrant (as adjusted as a result of all adjustments in the Exercise Price
in effect prior to such adjustment) by the Exercise Price in effect prior to
such adjustment and dividing the product so obtained by the adjusted Exercise
Price.

                  (c) Notice as to Adjustment. Upon any adjustment of the
Exercise Price and any increase or decrease in the number of shares of Common
Stock purchasable upon the exercise of the Warrant, then, and in each such case,
the Company within thirty (30) days thereafter shall give written notice
thereof, by first class mail, postage prepaid, addressed to each Holder as shown
on the books of the Company, which notice shall state the adjusted Exercise
Price and the increased or decreased number of shares purchasable upon the
exercise of the Warrants, and shall set forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

                  (d) Effect of Reorganization, Reclassification, Merger, etc.
If at any time while this Warrant is outstanding there should be (i) any capital
reorganization of the capital stock of the Company (other than the issuance of
any shares of Common Stock in subdivision of outstanding shares of Common Stock
by reclassification or otherwise and other than a combination of shares provided
for in Section 4(a) hereof), (ii) any consolidation or merger of the Company
with another corporation, or any sale, conveyance, lease or other transfer by
the Company of all or substantially all of its property to any other
corporation, which is effected in such a manner that the holders of Common Stock
shall be entitled to receive cash, stock, securities, or assets with respect to
or in exchange for Common Stock, or (iii) any dividend or any other distribution
upon any class of stock of the Company payable in stock of the Company of a
different class, other securities of the Company, or other property of the
Company (other than cash), then, as a part of such transaction, lawful provision
shall be made so that Holder shall have the right thereafter to receive, upon
the exercise hereof, the number of shares of stock or other securities or
property of the Company, or of the successor corporation resulting from such
consolidation or merger, or of the corporation to which the property of the
Company has been sold, conveyed, leased or otherwise transferred, as the case
may be, which the Holder would have been entitled to receive upon such capital
reorganization, reclassification of capital stock, consolidation, merger, sale,
conveyance, lease or other transfer, if this Warrant had been exercised
immediately prior to such capital reorganization, reclassification of capital
stock, consolidation, merger, sale, conveyance, lease or other transfer. In any
such case, appropriate adjustments (as determined by the Board of Directors of
the Company) shall be made in the application of the provisions set forth in
this Warrant (including the adjustment of the Exercise Price and the number of
Shares issuable upon the exercise of the Warrant) to the end that the provisions
set forth herein shall thereafter be applicable, as near as reasonably may be,
in relation to any shares or other property thereafter deliverable upon the
exercise of the Warrant as if the Warrant had been exercised immediately prior
to such capital reorganization, reclassification of capital stock, such
consolidation, merger, sale, conveyance, lease or other transfer and the Holder
had carried out the terms of the exchange as provided for by such capital
reorganization, consolidation or merger. The Company shall not effect any such
capital reorganization, consolidation, merger or transfer unless, upon or prior
to the consummation thereof, the successor corporation or the corporation to
which the property of the Company has been sold, conveyed, leased or otherwise
transferred shall assume by written instrument the obligation to deliver to the
Holder such shares of stock, securities, cash or property as in accordance with
the foregoing provisions such Holder shall be entitled to purchase.

         5. Redemption of Warrants

                  (a) Redemption Price. This Warrant may be redeemed at the
option of the Company following a period of thirty (30) consecutive trading days
where the per share average closing sale price of the Common Stock exceeds Two
and 50/100 Dollars ($2.50), on notice as set forth in Section 5(b) hereof, and
at a redemption price equal to One Cent ($.01) for each Share purchasable under
this Warrant; provided, however, that this Warrant may not be redeemed on or
before January 30, 2003. For purposes of this Section, the closing sale price of
the Common Stock shall be determined by the closing sale price as reported by
Nasdaq so long as the Common Stock is quoted on the Nasdaq National Market or
SmallCap Market Systems and, if the Common Stock is listed on a national
securities exchange, shall be determined by the last reported sale price on the
primary exchange on which the Common Stock is traded.

                  (b) Notice of Redemption. In the case of any redemption of
this Warrant, the Company shall give notice of such redemption to the Holder
hereof as provided in this Section 5(b). Notice of redemption to the Holder of
this Warrant shall be given by mailing by first-class mail, postage prepaid, a
notice of such redemption not less than thirty (30) days prior to the date fixed
for redemption. Any notice which is given in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives the notice. Each such notice shall specify the date fixed for
redemption, the place of redemption and the redemption price of $.01 per Share
at which this Warrant is to be redeemed, and shall state that payment of the
redemption price of the Warrant will be made up on surrender of this Warrant at
such place of redemption, and that if not exercised by the close of business on
the date fixed for redemption, the exercise rights of the Warrant shall expire
unless extended by the Company. Such notice shall also state the current
Exercise Price and the date on which the right to exercise the Warrant will
expire unless extended by the Company.

                  (c) Payment of Redemption Price. If notice of redemption shall
have been given as provided in Section 5(b), the redemption price of $.01 per
Share shall, unless the Warrant is theretofore exercised pursuant to the terms
hereof, become due and payable on the date and at the place stated in such
notice. On and after such date of redemption, the exercise rights of this
Warrant shall expire. On presentation and surrender of this Warrant at such
place of payment in such notice specified, this Warrant shall be paid and
redeemed at the redemption price of $.01 per Share within tem (10) days
thereafter.

         6. No Rights as Shareholders. This Warrant shall not entitle the Holder
as such to any voting rights or other rights as a shareholder of the Company.

         7. Governing Law. This Warrant shall be governed by and construed in
accordance with the laws of the State of Minnesota.

         8. Amendments and Waivers. The provisions of this Warrant may not be
amended, modified or supplemented, and waiver or consents to departures from the
provisions hereof may not be given, unless the Company agrees in writing and has
obtained the written consent of the Holder.

         9. Notices. All notices or communications hereunder, except as herein

<PAGE>

                                 LOAN AGREEMENT

         THIS LOAN AGREEMENT is dated as of June 5, 2002, by and between BARAN
ACQUISITION SUB, INC. ("Lender") on the one hand, and o2WIRELESS SOLUTIONS, INC.
("Borrower") and o2WIRELESS, INC., o2WIRELESS LIGHTING, INC., o2WIRELESS SYSTEMS
GROUP, INC., o2WIRELESS DEPLOYMENT, INC., o2WIRELESS SITE DEVELOPMENT, INC.,
YOUNG & ASSOCIATES, INC., o2WIRELESS MICHIGAN, INC., and o2WIRELESS NORTH
CAROLINA, INC. (collectively, "Affiliate Guarantors") on the other hand.

         WHEREAS, Lender is willing to provide working capital advances to
Borrower subject to the conditions and protections provided by this Working
Capital Loan Agreement.

         IN CONSIDERATION of the foregoing and the mutual covenants, conditions
and agreements set forth herein and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, it is hereby
agreed as follows:

                                    ARTICLE I

                                    THE LOAN

         1.1.     Working Capital Advances/Use of Loan Proceeds/Structure of
Commitment.  (a) From time to time prior to the date upon which Lender
determines to withdraw from its commitments under this Loan Agreement and
subject to the terms and conditions set forth in this Loan Agreement, Lender
agrees, for itself only, to extend Working Capital Advances to Borrower. All
Working Capital Advances shall be evidenced by a Working Capital Note the form
of which is attached hereto as Exhibit A, and Borrower is obligated to pay to
Lender the amount of Working Capital Advances actually made by Lender, together
with interest on the principal amount of the Working Capital Advances which
remain outstanding from time to time.

                  (b)      Lender agrees that at a minimum it will initially
advance, upon satisfaction of all conditions precedent other than those
conditions Lender has determined to waive, if any, a minimum of Five Million
Dollars ($5,000,000). The proceeds of such initial advance shall be used as
provided in Schedule 1.1(b). In addition, no later than (i) the date Borrower
files its Form 10-Q for the quarter ended June 30, 2002 or (ii) August 15, 2002,
Lender shall advance to Borrower at least the lesser of (x) $3,000,000 or (y)
the amount of Borrower's Loss for the quarter ended June 30, 2002. If this Loan
Agreement is in effect as of the later of (i) the date Borrower files its Form
10-Q for the quarter ended September 30, 2002 or (ii) November 15, 2002, Lender
shall advance to Borrower, at its discretion, an amount equal to Borrower's Loss
for the quarter ended September 30, 2002. For purposes hereof, Loss shall mean
Borrower's consolidated earnings before interest, taxes, depreciation,
amortization, non-cash restructuring expenses and any accrued and unpaid
management fees due to Lender. In no event, however, will Lender have any
obligation or commitment to extend any Working Capital Advances to Borrower
under this Loan Agreement following the earliest of (i) the occurrence of an
Event of Default or (ii) November 15, 2002.

                                      -2-
<PAGE>

         1.2.     Interest.  (a) Prior to an Event of Default (and except as
otherwise provided herein), the unpaid principal balance of the Working Capital
Advances shall bear interest at the rate of two percent (2%) in excess of the
prime rate of interest as announced by CitiBank, N.A. from time to time. If all
the Working Capital Advances are not paid in full by November 15, 2002, the
interest rate shall thereupon increase by five percentage points.

                  (b)      All interest due and other amounts due under this
Loan Agreement and a Working Capital Note shall be computed for the actual
number of days elapsed and on the basis of a 360-day year.

         1.3.     Notice of Requirement.  Borrower, on behalf of itself and/or
the Affiliate Guarantors shall advise Lender from time to time of the specific
requirements it possesses for which additional working capital is needed to
operate its consolidated business. Upon such advice, Lender shall have the
right, but not the obligation, to advance funds to Borrower and to specify the
specific use of such funds; provided, however, that Lender shall be obligated to
fund the amount, up to $3,000,000, of Borrowers Loss for the quarter ended June
30, 2002. Lender also reserves the right to make advances to Borrower at such
time and in such amounts as Lender determines is necessary to enable Borrower
and the Affiliated Guarantors to meet the respective obligations of their
businesses.

         1.4.     Warranty.  Borrower's receipt of an advance from Lender shall
automatically constitute a warranty by Borrower to the Lender that, on the date
of the advance: (a) all of the representations and warranties of Borrower
contained in this Loan Agreement shall be true and correct on such date as
though made on such date; and (b) no Default or Event of Default shall exist on
such date.

         1.5.     Payments.  (a) The outstanding unpaid principal balance of all
Working Capital Advances, shall be paid in full on the earlier of Lender's
demand for payment, which in no event shall such demand be made prior to
November 15, 2002 or the occurrence of an Event of Default. Notwithstanding such
payment terms, while the Subordination Agreement of even date herewith among
Borrower, Lender and Wachovia Bank, National Association (the "Bank")
("Subordination Agreement") is in effect, no payments shall be made by Borrower
to Lender.

                  (b)      All payments owed by Borrower to Lender under this
Loan Agreement and the Working Capital Advances, including without limitation,
such sums due under each Note shall be made without any counterclaim, offset,
recoupment, withholding, deduction or other reduction, deferment or abatement
for any reason whatsoever.

         1.6.     Affiliate Guaranty.  (a) The Affiliate Guarantors hereby
jointly and severally guarantee to the Lender the prompt payment in full when
due (whether at stated maturity, by acceleration or otherwise) of all Working
Capital Advances (such advances herein called, collectively, the "Guaranteed
Obligations"), in each case strictly in accordance with the terms hereof. The
Affiliate Guarantors hereby further jointly and severally agree that if Borrower
shall fail to pay in full when due (whether at stated maturity, by acceleration
or otherwise) any of the Guaranteed Obligations, the Affiliate Guarantors will
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due

                                      -3-
<PAGE>

(whether at extended maturity, by acceleration or otherwise) in accordance with
the terms of such extension or renewal.

                  (b)      The obligations of the Affiliate Guarantors hereunder
are absolute and unconditional, joint and several, irrespective of the value,
genuineness, validity, regularity or enforceability of the obligations of
Borrower under this Agreement, the Working Capital Notes or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor
(other than, subject to paragraph (c) below, full payment and satisfaction of
all Guaranteed Obligations), it being the intent of this section that the
obligations of the Affiliate Guarantors hereunder shall be absolute and
unconditional, joint and several, under any and all circumstances. Without
limiting the generality of the foregoing, it is agreed that, to the extent
permitted by applicable law, the occurrence of any one or more of the following
shall not alter or impair the liability of the Affiliate Guarantors hereunder
which shall remain absolute and unconditional as described above:

                           (i)      at any time or from time to time, without
                           notice to any of the Affiliate Guarantors, the time
                           for any performance of or compliance with any of the
                           Guaranteed Obligations shall be extended, or such
                           performance or compliance shall be waived;

                           (ii)     any of the acts mentioned in any of the
                           provisions of this Agreement or the Note or any other
                           agreement or instrument referred to herein or therein
                           on the part of Borrower to be done shall fail to be
                           done or be omitted;

                           (iii)    the maturity of any of the Guaranteed
                           Obligations shall be accelerated, or any of the
                           Guaranteed Obligations shall be modified,
                           supplemented or amended in any respect, or any right
                           under this Agreement or the Note shall be waived or
                           any other guarantee of any of the Guaranteed
                           Obligations or any security therefor shall be
                           released or exchanged in whole or in part or
                           otherwise dealt with; or

                           (iv)     any lien or security interest granted to, or
                           in favor of, the Lender as security for any of the
                           Guaranteed Obligations shall fail to be perfected.

                           The Affiliate Guarantors hereby expressly waive
                           diligence, presentment, demand of payment, protest
                           and all notices whatsoever, and any requirement that
                           Lender exhaust any right, power or remedy or proceed
                           against Borrower under this Agreement or the Note.

                  (c)      The obligations of the Affiliate Guarantors hereunder
shall be automatically reinstated if and to the extent that for any reason any
payment by or on behalf of Borrower in respect of the Guaranteed Obligations is
rescinded or must be otherwise restored by Lender or any subsequent holder of
any of the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise and the Affiliate Guarantors jointly
and

                                      -4-
<PAGE>

severally agree that they will indemnify Lender on demand for all reasonable
costs and expenses (including, without limitation, reasonable fees and
disbursements of legal counsel) incurred by Lender in connection with such
rescission or restoration, including any such costs and expenses incurred in
defending against any claim alleging that such payment constituted a preference,
fraudulent transfer or similar payment under any bankruptcy, insolvency or
similar law.

                  (d)      Each Affiliate Guarantor hereby subordinates to
Lender all rights of subrogation or contribution against Borrower, whether
arising by contract or operation of law (including, without limitation, any such
right arising under the Bankruptcy Code) or otherwise by reason of any payment
by it pursuant to the provisions hereof until all Working Capital Advances
(other than any constituting contingent indemnity obligations) are fully paid
and satisfied.

                  (e)      The Affiliate Guarantors jointly and severally agree
that, as between the Affiliate Guarantors and Lender, the Guaranteed Obligations
may be declared to be forthwith due and payable as provided herein (and shall be
deemed to have become automatically due and payable in the circumstances
provided herein) for purposes hereof, notwithstanding any stay, injunction or
other prohibition preventing such declaration (or such obligations from becoming
automatically due and payable) as against Borrower and that, in the event of
such declaration in accordance with the terms hereof (whether or not due and
payable by the Borrower) shall forthwith become due and payable by the Affiliate
Guarantors for purposes hereof.

                  (f)      Each Affiliate Guarantor hereby acknowledges that its
guaranty herein constitutes an instrument for the payment of money.

                  (g)      The guaranty set forth herein is a continuing
guaranty, and shall apply to all Guaranteed Obligations, whenever and howsoever
arising.

                  (h)      The Affiliate Guarantors hereby agree, as between
themselves, that if any Affiliate Guarantor shall become an "Excess Funding
Guarantor" (as defined below) by reason of the payment by such Affiliate
Guarantor of any Guaranteed Obligations, each other Affiliate Guarantor shall,
on demand of such Excess Funding Guarantor (but subject to the next sentence),
pay to such Excess Funding Guarantor an amount equal to such Affiliate
Guarantor's "Pro Rata Share" (as defined below and determined, for this purpose,
without reference to the properties, debts and liabilities of such Excess
Funding Guarantor) of the "Excess Payment" (as defined below) in respect of such
Guaranteed Obligations. The payment obligation of an Affiliate Guarantor to any
Excess Funding Guarantor under this Section shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Affiliate Guarantor under the other provisions of this Section 1.11 and such
Excess Funding Guarantor shall not exercise any right or remedy with respect to
such excess until payment and satisfaction in full of all such obligations. For
purposes hereof, (i) "Excess Funding Guarantor" means, in respect of any
Guaranteed Obligations, an Affiliate Guarantor that has paid an amount in excess
of its Pro Rata Share of such Guaranteed Obligations, (ii) "Excess Payment"
means, in respect of any Guaranteed Obligations, the amount paid by an Excess
Funding Guarantor in excess of its Pro Rata Share of such Guaranteed Obligations
(iii) "Pro Rata Share" means, for any Affiliate Guarantor, the ratio (expressed
as a percentage) of (x) the amount by which the aggregate present fair saleable
value of all assets of such Affiliate Guarantor (excluding any shares of stock
of any

                                      -5-
<PAGE>

other Affiliate Guarantor) exceeds the amount of all the debts and liabilities
of such Affiliate Guarantor (including contingent, subordinated, unmatured and
unliquidated liabilities, but excluding the obligations of such Affiliate
Guarantor hereunder and any obligations of any other Affiliate Guarantor that
have been guaranteed by such Affiliate Guarantor) to (y) the amount by which the
aggregate fair saleable value of all assets of all of the Affiliate Guarantors
exceeds the amount of all the debts and liabilities (including contingent,
subordinated, unmatured and unliquidated liabilities, but excluding the
obligations of the Affiliate Guarantor hereunder) of the Affiliate Guarantors,
determined as of the date hereof.

                  (i)      In any action or proceeding involving any state
corporate law, or any state or Federal bankruptcy, insolvency, reorganization or
other law affecting the rights of creditors generally, if the obligations of the
Affiliate Guarantors hereunder, after giving effect to the contribution rights
provided herein above, would otherwise be held or determined to be void, invalid
or unenforceable, or subordinated to the claims of any other creditors, on
account of the amount of its liability hereunder, then, notwithstanding any
other provision hereof to the contrary, the amount of such liability shall,
without any further action by any Affiliate Guarantor or Lender, be
automatically limited and reduced to the highest amount that is valid and
enforceable and not subordinated to the claims of other creditors as determined
in such action or proceeding.

         1.7.     Security Interest.  (a) As security for the due and prompt
repayment and performance of any and all of the Working Capital Advances and the
performance of all other obligations and covenants of Borrower and Affiliated
Guarantors hereunder, certain or contingent, now existing or hereafter arising,
which are now, or may at any time or times hereafter be owing by Borrower or
Affiliated Guarantors, Borrower and each Affiliated Guarantor hereby pledges and
assigns to Lender and gives Lender a continuing security interest in and general
Lien upon and right of set-off against, all right, title and interest of
Borrower or Affiliated Guarantor in and to the Collateral, whether now owned or
hereafter acquired by Borrower or Affiliated Guarantor, and all proceeds and
products derived therefrom.

                  (b)      Except as herein or by applicable law otherwise
expressly provided, Lender shall not be obligated to exercise any degree of care
in connection with any Collateral in its possession, to take any steps necessary
to preserve any rights in any of the Collateral or to preserve any rights
therein against prior parties, and Borrower or each Affiliated Guarantor agrees
to take such steps. In any case Lender shall be deemed to have exercised
reasonable care if it shall have taken such steps for the care and preservation
of the Collateral or rights therein as Borrower and each Affiliated Guarantor
may have reasonably requested Lender to take and Lender's omission to take any
action not requested by Borrower or an Affiliated Guarantor shall not be deemed
a failure to exercise reasonable care. In no event, however, shall Lender be
obligated to take any actions requested of it. No segregation or specific
allocation by Lender of specified items of Collateral against any liability of
Borrower and each Affiliated Guarantor shall waive or affect any security
interest in or Lien against other items of Collateral or any of Lender's
options, powers or rights under this Agreement or otherwise arising.

                  (c)      Upon the occurrence and continuation of an Event of
Default, Lender may at any time and from time to time, with or without notice to
any Borrower or an Affiliated

                                      -6-
<PAGE>

Guarantor, (i) transfer into the name of Lender or the name of Lender's nominee
any of the Collateral, (ii) notify any Account Debtor or other obligor of any
Collateral to make payment thereon direct to Lender of any amounts due or to
become due thereon and (iii) receive and after a Default or Event of Default
direct the disposition of any proceeds of any Collateral.

                  (d)      Borrower and each Affiliated Guarantor authorizes
Lender at Borrower's expense to file any financing statements relating to the
Collateral and such other documents that are required for filing with the United
States Patent and Trademark Office in order to perfect Lender's security
interest (without Borrower's or Affiliated Guarantor's signatures thereon) which
Lender deems appropriate and Borrower and each Affiliated Guarantor irrevocably
appoints Lender as its attorney-in-fact to execute any such financing
statements, documents and/or control agreements in their name and to perform all
other acts, at their expense, which Lender deems appropriate to perfect and to
continue perfection of the security interest of Lender. Borrower and each
Affiliated Guarantor hereby appoints Lender as its attorney-in-fact to endorse,
present and collect on its behalf and in its name any draft, checks or other
documents necessary or desirable to collect any amounts which they may be owed.
The proceeds realized from the sale or other disposition of any Collateral may
be applied, after allowing two (2) Business Days for collection, first to the
reasonable costs, expenses and attorneys' fees and expenses incurred by Lender
for collection and for acquisition, completion, protection, removal, storage,
sale and delivering of the Collateral; secondly, to interest due upon any of the
Working Capital Advances; and thirdly, to the principal amount of the Working
Capital Advances. If any deficiency shall arise, Borrower and the Affiliated
Guarantor shall remain jointly and severally liable to Lender therefor.

                  (e)      Borrower and each Affiliated Guarantor authorizes
Lender without affecting their joint and several obligations hereunder from time
to time (i) to take from any party and hold additional Collateral or guaranties
for the payment of the Working Capital Advances or any part thereof, and to
exchange, enforce or release such collateral or guaranty of payment of the
Working Capital Advances or any part thereof and to release or substitute any
endorser or guarantor or any party who has given any security interest in any
collateral as security for the payment of the Working Capital Advances or any
part thereof or any party in any way obligated to pay the Indebtedness or any
part thereof; and (ii) upon the occurrence of any Event of Default to direct the
manner of the disposition of the Collateral and the enforcement of any
endorsements, guaranties, letters of credit or other security relating to the
Indebtedness or any part thereof as Lender in its sole discretion may determine.

                  (f)      Upon the occurrence and continuation of an Event of
Default, Lender may notify any Account Debtor of Lender's security interest and
may direct such Account Debtor to make payment directly to Lender for
application against the Working Capital Advances. Any such payments received by
or on behalf of Borrower at any time, whether before or after an Event of
Default, shall be the property of Lender, shall be held in trust for Lender and
not commingled with any other assets of any Person. Lender shall have the right
to apply any proceeds of Collateral to such of the Working Capital Advances as
it may determine.

                  (g)      Borrower and each Affiliated Guarantor hereby waives
any right it may have to require marshaling of its assets.

                                      -7-
<PAGE>

                  (h)      Borrower and each Affiliated Guarantor will cooperate
with Lender in obtaining control of, or control agreements with respect to,
Collateral for which control or a control agreement is required for perfection
of the Lender's security interest.

                  (i)      For purposes of this Loan Agreement "Collateral"
means the following property of Borrower and each Affiliate Guarantor, wherever
located and whether now owned by any Borrower or hereafter acquired: (a) all
Inventory; (b) all General Intangibles; (c) all Accounts and Chattel Paper and
any other instrument or intangible representing payment for goods or services;
(d) all Equipment (other than Equipment subject to a Permitted Lien); (e) all
Investment Property; (f) all shares of stock that Borrower holds in the
Affiliate Guarantors (subject to the prior pledging thereof to the Bank): and
(g) all parts, replacements, substitutions, profits, products and cash and
non-cash proceeds of any of the foregoing (including insurance proceeds payable
by reason of loss or damage thereto) in any form and wherever located.
Collateral shall include all written or electronically recorded books and
records relating to any such Collateral and other rights relating thereto. The
capitalized terms above shall have the meanings assigned thereto under the
Uniform Commercial Code as adopted in the State of Georgia.

                                   ARTICLE III

         Borrower and each Affiliate Guarantor hereby jointly and severally
represent and warrant to Lender as follows:

         3.1.     Organization and Qualification.  Borrower and each Affiliate
Guarantor is a corporation duly and validly organized and existing under the
laws of the state of its incorporation and has the corporate power and all
reasonably necessary licenses, permits and franchises to own its assets and
properties and to carry on its business as now conducted or presently
contemplated. Borrower and each Affiliate Guarantor is duly licensed or
qualified to do business and is in good standing in all jurisdictions in which
failure to do so would have a material adverse effect on its business or
financial condition.

         3.2.     Financial Statements.  All of the financial statements of
Borrower heretofore furnished to Lender by Borrower (i) are accurate and
complete in all material respects and fairly

<PAGE>

present the financial condition, assets, liabilities, results of the
consolidated operations of Borrower, cash flow and other information included
therein for the periods covered thereby and as of the relevant dates thereof,
(ii) were prepared based upon true, correct and complete information that
borrower's management provided and (iii) were prepared in accordance with
generally accepted accounting principles applied on a consistent basis, subject
in the case of interim financial statements to audit and normal year-end
adjustments. There has been no material adverse change in the business,
properties or condition (financial or otherwise) of Borrower since the date of
the latest of such financial statements except for such matters otherwise
disclosed to Lender. There are no any material liabilities, indebtedness and
obligations of any nature (whether accrued, absolute, contingent or otherwise)
of Borrower or an Affiliate Guarantor not disclosed in writing to Lender.

         3.3.     Authorization; Enforceability.  The making, execution,
delivery and performance of this Loan Agreement, the Working Capital Notes and
all other documents to be delivered by Borrower to the Lender in connection with
this Loan Agreement, have been duly authorized by all necessary corporate action
of Borrower and each of the Affiliate Guarantors. This Loan Agreement and the
initial Working Capital Note are, and subsequent Working Capital Notes will be,
the valid and binding obligations of Borrower and each Affiliate Guarantor and
are and will be enforceable against Borrower and each Affiliate Guarantor and
are and will be effective in accordance with their respective terms. No consent
or authorization is required in connection with this Loan Agreement or any
Working Capital Advances made hereunder other than the consent of the Bank which
consent has been obtained. This Loan Agreement grants and creates a valid
security interest in the Collateral for the benefit of Lender and such security
interest will be validly perfected upon appropriate filings of financing
statements, as to the collateral for which financing statements are required to
perfect security interests, and with the filing of requisite documents with the
United States Patent and Trademark Office to perfect the security interests in
registered trademarks, service marks and patents.

         3.4      Compliance with Other Instruments, etc.  Borrower and each
Affiliate Guarantor is not now, nor after given effect to the Working Capital
Loan will be, in violation of its articles of incorporation or by-laws. Borrower
is not, nor after giving effect to the Working Capital Loan will be, in material
violation of any term of any agreement or instrument to which it is a party or
by which it or any of its properties or assets is bound, or any term of any
applicable Law, ordinance, rule or regulation of any governmental authority or
any term of any applicable order, judgment or decree of any court, arbitrator or
governmental authority, the consequences of any which violation (or all such
violations in the aggregate) would reasonably be expected to have a material
adverse effect; and the execution, delivery and performance of this Agreement
and the Working Capital Notes will not result in any material violation of or be
in material conflict with or constitute a default under any such term or result
in the creation of (or impose any obligation on the Borrower to create) any Lien
upon any of the properties or assets of the Borrower pursuant to any such term.

         3.5.     Taxes.  Borrower and each Affiliate Guarantor has filed all
federal, state, foreign and local tax returns which were required to be filed
(subject to any valid extensions of the time for filing), and has paid, or made
provision for the payment of, all taxes owed by it where the failure to so file
or pay such taxes would have any material adverse effect on the assets or

                                      -10-
<PAGE>

properties of the Borrower or such Affiliate Guarantor or cause any material
adverse change in the financial condition of the Borrower or such Affiliate
Guarantor, and no tax deficiencies have been assessed or, to Borrower's
knowledge, proposed against Borrower or an Affiliate Guarantor.

         3.6.     Accuracy of Information.  All information, certificates or
statements by Borrower and each Affiliate Guarantor given in, or pursuant to,
this Loan Agreement shall be accurate, true and complete when given in all
material respects.

         3.7.     Title to Property.  Borrower has good title to, or a valid
leasehold interest in, all assets and properties shown on Borrower's most
recently delivered financial statements and necessary to conduct its business as
now conducted or proposed to be conducted, and there are no Liens on any of the
assets or properties of Borrower other than Permitted Liens. Borrower and each
Affiliate Guarantor has all licenses, permits, franchises, patents, copyrights,
trademarks and trade names, or rights thereto, reasonably necessary to conduct
its business as now conducted or proposed to be conducted, and Borrower does not
know of any conflict with or violation of any valid rights of others with
respect thereto.

         3.8.     ERISA.  Borrower has no knowledge that any Plan is in
noncompliance in any material respect with the applicable provisions of ERISA or
the Internal Revenue Code. Borrower has no knowledge of any pending or
threatened litigation or governmental proceeding or investigation against or
relating to any Plan, nor has any knowledge of any reasonable basis for any
material proceedings, claims or actions against or relating to any Plan.
Borrower has no knowledge that Borrower has incurred any "accumulated funding
deficiency" within the meaning of Section 302(a)(2) of ERISA in connection with
any Plan. Borrower has no knowledge that there has been any Reportable Event or
Prohibited Transaction (as such terms are defined in ERISA) with respect to any
Plan, the occurrence of which would have a material adverse effect on the
business or condition (financial or otherwise) of Borrower, or that Borrower has
incurred any liability to the PBGC under Section 4062 of ERISA in connection
with any Plan.

         3.9.     Fiscal Year.  Borrower's fiscal year ends on December 31.

         3.10.    Compliance With Laws.  Neither Borrower or any Affiliate
Guarantor nor any of the assets of Borrower or an Affiliate Guarantor is in
violation of any Law to which Borrower or any Affiliate Guarantor or their
assets is subject which would have a material adverse effect on Borrower, an
affiliate Guarantor or their assets.

         3.11.    Other Environmental Conditions.  To the best of Borrower's
knowledge after reasonable investigation, there are no conditions existing
currently or likely to exist during the term of this Loan Agreement that would
reasonably be expected to subject Borrower or any Affiliate Guarantor to
damages, penalties, injunctive relief or clean-up costs under any Environmental
Laws, or that would reasonably be expected to require investigation, clean-up,
removal or some other remedial action by Borrower or any Affiliate Guarantor
under Environmental Laws which remedial action would materially and adversely
affect the business or financial condition of the Borrower or an Affiliate
Guarantor, cause any material adverse change

                                      -11-
<PAGE>

in the assets and properties of the Borrower or an Affiliate Guarantor or cause
any material impairment of the right to carry on the business of the Borrower or
an Affiliate Guarantor.

         3.12.    Environmental Judgments, Decrees and Orders.  No materially
adverse judgment, decree, order or citation related to or arising out of
Environmental Laws is applicable to or binds Borrower or an Affiliate Guarantor,
or its Facilities or the owner of any of the Facilities.

         3.13.    No Claims.  Borrower represents, warrants and agrees that
neither Borrower nor to its knowledge any of its shareholders whose beneficial
ownership is reflected in Borrower's latest annual report or proxy statement
filed with the Securities and Exchange Commission, directors, officers, agents
or representatives possess any lawsuit, demand, claim, cause of action, right to
money or damages, right of offset or recoupment or any other right or claim
whatsoever against the Lender. Borrower has also not received any notice that
any shareholders of Borrower are contemplating taking any action against the
Company that arises under federal or state securities laws.

                                   ARTICLE IV

                               NEGATIVE COVENANTS

         From and after the date of this Loan Agreement and until the entire
amount of principal of and interest due on the Working Capital Advances, and all
other fees and payments due under this Loan Agreement, and the Working Capital
Notes, and any other obligations of Borrower to Lender are paid in full,
Borrower shall not do or engage (and shall prevent any Affiliate Guarantor from
doing or engaging) in any of the following without the prior written consent of
Lender; provided, however, that if any of the following limitations or
restrictions imposed on Borrower and the Affiliate Guarantors are more
restrictive than the covenants set forth in the Credit Agreement, the
limitations and restrictions in this Article IV shall be deemed automatically
amended to be consistent in all material respects with such covenants:
