                  hereafter approved by Lender in writing prior to their

                  hereof will be, the sole beneficial owner of the Collateral,
                  free and clear of any mortgage, lien, pledge, charge, security

                  terms against the party obligated to pay the same (the "Third
                  Party Debtor"), and the amount represented by the Undersigned
                  to Lender from time to time as owing by each Third Party
                  Debtor or by all Third Party Debtors will be the correct
                  amount actually and unconditionally owing by such Third Party

                  Security Agreement or otherwise.

                  customers) and other tangible property is at and will be kept
                  at one of such locations or at such other locations as the
                  Undersigned shall specify in writing to Lender and, subject to
                  the provisions of this General Security Agreement, none of the
                  Collateral shall be moved therefrom without the prior written
                  consent of Lender.

         (g)      The Undersigned has full corporate power, authority and
                  capacity to execute, deliver and perform all of its

<PAGE>   5



         (j)      This General Security Agreement when duly executed and
                  delivered by the Undersigned will be a legal, valid and
                  binding obligation of the Undersigned, enforceable against it
                  in accordance with its terms, subject only as such enforcement
                  may be limited by bankruptcy, insolvency and any other similar
                  laws or proceedings relating to the enforcement of creditors'
                  rights generally and to the extent that equitable remedies
                  such as specific performance and injunction are in the
                  discretion of a court of competent jurisdiction.

         (k)      There is no charter, by-law, or capital stock provision of the
                  Undersigned and no provision of any indenture, mortgage, lease
                  or agreement, written or oral, to which the Undersigned is a
                  party or under which the Undersigned is obligated, nor to the
                  knowledge of the Undersigned is there any law, statute, rule
                  or regulation, or any judgment, decree or order of any court
                  or agency binding on the Undersigned, which would be violated,
                  contravened, breached by or under which default would occur as
                  a result of the execution and delivery of this General
                  Security Agreement or by the performance of any provision,
                  condition, covenant or other term hereof.

         (l)      There is no litigation, tax claim, proceeding or dispute in
                  progress, pending or, to the knowledge of the Undersigned,
                  threatened, against, relating to or affecting the Undersigned
                  or its property, the adverse determination of which might
                  adversely affect the Undersigned's financial condition or
                  operations or impair the Undersigned's ability to perform its
                  obligations hereunder or under any other instrument or
                  agreement required hereunder.

         (m)      The undersigned is solvent in the sense that the fair saleable
                  value of all of its assets exceeds the total amount of its
                  liabilities.

4.       COVENANTS OF THE UNDERSIGNED.

         So long as this General Security Agreement remains in effect, the
Undersigned hereby covenants and agrees that:

         (a)      Without the prior written consent of Lender, the Undersigned
                  shall not assume, create or permit the creation of any
                  mortgage, lien, charge, pledge, security interest,

                  limiting the generality of the foregoing, any purchase money

         (b)      The Undersigned shall diligently defend its title to the
                  Collateral against the claims and demands of all persons

                                        5

<PAGE>   6



         (c)      The Undersigned shall diligently maintain, use and operate the
                  Collateral and shall carry on and conduct its business in a
                  proper and efficient manner so as to preserve and protect the
                  Collateral and the earnings, incomes, rents, issues and
                  profits thereof.

         (d)      The Undersigned shall (i) cause the Collateral to be properly
                  insured and kept properly insured with reputable insurers as
                  shall be acceptable to Lender against loss or damage by fire,
                  windstorm, water, theft, malicious mischief and extended
                  coverage, and such other risks as Lender may require, to the
                  full insurable value thereof, (ii) either assign the insurance
                  policies to Lender or have the loss thereunder made payable to
                  Lender, as Lender may require, (iii) deliver to Lender the
                  originals of such policies or certified copies thereof with

                  insured, as appropriate, and (iv) deliver to Lender evidence
                  of such insurance satisfactory to Lender. Should the
                  Undersigned neglect to maintain such insurance, Lender may
                  (but shall not be required to) insure the Collateral, and any
                  premiums paid by Lender together with interest thereon shall
                  be payable by the Undersigned to Lender upon demand.

         (e)      The Undersigned shall keep the Collateral free and clear of
                  all taxes, assessments, claims, liens and encumbrances except
                  for ("Permitted Liens"):

                  (i)      security interests and liens at any time granted in
                           favor of Lender;

                  (ii)     liens for taxes that are not yet due or are being
                           contested in good faith by the Undersigned by
                           appropriate proceedings promptly instituted and
                           diligently conducted, when the Undersigned has
                           established appropriate reserves therefor, but only
                           if nonpayment of such taxes will not have a material
                           adverse effect upon the business, operations,
                           properties, condition (financial or otherwise), or
                           the business prospects of the Undersigned or the
                           Collateral and no lien is imposed upon the
                           Undersigned's assets with respect to such taxes
                           unless such lien is at all times junior and
                           subordinate in priority to the security interests and
                           liens in favor of Lender;

                  (iii)    statutory liens arising in the ordinary course of the
                           Undersigned's business by operation of law or
                           regulation, but only if (a) payment in respect of any
                           such lien is not at the time required or such liens
                           are being contested in good faith by the Undersigned
                           by appropriate proceedings promptly instituted and
                           diligently conducted, when the Undersigned has
                           established appropriate reserves therefor, (b) such
                           liens do not, in the aggregate, materially detract
                           from the value of the Collateral or materially impair
                           the use thereof in the operation of the Undersigned's
                           business, and (c) such liens are at all times junior
                           and subordinate to the security interests and liens
                           in favor of Lender; and

                  (iv)     such other liens as Lender may hereafter approve in
                           writing.

         (f)      The Undersigned shall pay all rents, taxes, rates, levies,
                  assessments, government fees, dues and other charges of every
                  nature lawfully levied, assessed or imposed against or in
                  respect of the Undersigned or the Collateral or any part
                  thereof as and when the same shall become due and payable, and
                  shall exhibit to Lender, when required, the receipts and
                  vouchers establishing such payments.

         (g)      The Undersigned shall preserve and maintain its corporate
                  existence, rights, franchises and privileges and shall duly
                  observe and conform to all valid requirements of any
                  governmental authority relative to its business, credit or any
                  of the Collateral and all covenants, terms and conditions upon
                  or under which the Collateral is held.

         (h)      The Undersigned shall notify Lender in writing:

                  (i)      promptly after the Undersigned's learning thereof, of
                           the commencement of any litigation or claims before
                           any court, administrative board or other tribunal
                           relating to or affecting the Undersigned or any of
                           its properties, whether or not the claim is
                           considered by the Undersigned to be covered by
                           insurance;

                  (ii)     of the occurrence of any event or the existence of
                           any fact which renders any representation or warranty
                           in this General Security Agreement inaccurate,
                           incomplete or misleading;

                  (iii)    promptly after the Undersigned's learning thereof, of

                           guaranty or other similar agreement relating to any
                           indebtedness of the Undersigned exceeding $300,000;

                  (iv)     promptly after the occurrence thereof, of any Event
                           of Default;

                  (v)      promptly after the occurrence thereof, of any default
                           by any obligor under any note or other evidence of
                           indebtedness payable to the Undersigned;

                  (vi)     promptly after the occurrence thereof, of any
                           judgment rendered against the Undersigned in an
                           amount exceeding $300,000;

                  (vii)    at least thirty (30) days prior to the occurrence
                           thereof, the details of any proposed material

                           occurrence thereof, the details of any acquisition of
                           any vehicle, mobile home, trailer, boat, aircraft or

                  (viii)   promptly after the Undersigned's learning thereof, of
                           any event which occurs that would have an adverse
                           effect upon the Collateral or upon the financial
                           condition of the Undersigned, including, without
                           limiting the generality of the foregoing, any loss of
                           or damage to the Collateral, any default by any Third
                           Party Debtors in the payment or other performance of
                           its obligations with respect to the Collateral or the
                           return to or repossession by the Undersigned of
                           Collateral where such return or repossession of
                           Collateral is material in relation to the business of
                           the Undersigned; and

                  (ix)     promptly (and in any event within 2 Business Days)
                           after the Undersigned's learning thereof, of the
                           termination of or assertion by a landlord of the
                           Undersigned of any default under any lease between
                           such landlord and the Undersigned.

         (i)      The Undersigned shall not sell, exchange, transfer, lease,
                  assign or otherwise dispose of or change the use of the
                  Collateral or any interest therein (except for sales of
                  Inventory in the ordinary course of the Undersigned's business
                  so long as no Event of Default exists hereunder) or modify,
                  amend, discount, compromise or terminate any Chattel Paper,
                  Document of Title, Instrument, Security, Intangible or
                  Accounts, or assign, factor or discount any of the Accounts to
                  a third party, without the prior written consent of Lender.
                  All proceeds of the Collateral shall be held in trust by the
                  Undersigned for Lender.

         (j)      The Undersigned shall prevent the Collateral, except the
                  Collateral sold or leased as permitted hereby, from being or
                  becoming an accession to other property not covered by this
                  General Security Agreement.

         (k)      The Undersigned shall not create or permit the creation of any
                  trust deed or similar instrument without the prior written
                  consent of Lender.

         (l)      The Undersigned shall keep proper books of account in
                  accordance with sound accounting practice and complete and
                  accurate records concerning the Collateral. The Undersigned
                  shall from time to time forthwith, on request, furnish to
                  Lender in writing all information and statements, including
                  financial information and statements, requested relating to
                  the Undersigned's business, the Collateral or any part
                  thereof, and Lender or its authorized agents shall be entitled
                  from time to time to inspect the tangible Collateral wherever
                  located, including, without limiting the generality of the
                  foregoing, the books and records, financial or otherwise,
                  maintained by the Undersigned with respect to the Collateral,
                  and to make copies thereof and take extracts therefrom, and
                  for such purpose Lender or its authorized agents shall have
                  access to all places where the Collateral or any part thereof
                  is located and to all premises occupied by the Undersigned.


                                        8

         (m)      The Undersigned shall keep all Collateral, other than
                  Inventory in transit, at one or more locations set forth in
                  Schedule A attached hereto, and all such Collateral shall not,
                  without the prior written consent of Lender, be moved
                  therefrom, except prior to an Event of Default, for (i) sales
                  of Inventory in the ordinary course of business and (ii) the
                  storage of Inventory at locations within Maryland and Georgia
                  other than those shown on Schedule A if, prior to storage of
                  any such Inventory at such locations, all filings that are
                  necessary to perfect or continue to perfect Lender's security
                  interests in or liens upon the Collateral have been filed.

         (n)      The Undersigned shall provide Lender with all agreements
                  hereafter entered into between the Undersigned and any
                  landlord or warehouseman which owns any premises at which any
                  Inventory may hereafter be kept. The Undersigned shall obtain
                  a lien waiver or subordination, in the form requested by
                  Lender, from each landlord of a premises leased by the
                  Undersigned.

         (o)      The Undersigned shall furnish Lender with Inventory reports,
                  which reports shall describe the Inventory by each location
                  and be substantially in the form requested by Lender, at such
                  times as Lender may request. The Undersigned shall conduct a
                  physical inventory no less frequently than annually and shall
                  provide to Lender reports based on each such physical
                  inventory promptly thereafter, together with such supporting
                  information as Lender shall reasonably request.

         (p)      The Undersigned shall deliver to Lender from time to time
                  promptly upon request such other information concerning the
                  Collateral, the Undersigned and the Undersigned's business and
                  affairs as Lender may reasonably request.

         (q)      The Undersigned shall not change its name or the location of
                  its chief executive office or principal place of business
                  without having given Lender at least sixty (60) days prior
                  written notice thereof.

5.       USE AND VERIFICATION OF COLLATERAL.

         Subject to compliance with the Undersigned's covenants contained herein
and paragraph 7 hereof, the Undersigned may, until an Event of Default, possess,
operate, collect, use, enjoy and deal with the Collateral in the ordinary course
of the Undersigned's business in any lawful manner not inconsistent with the
provisions of this General Security Agreement; provided always that Lender shall
have the right at any time and from time to time to verify the existence and
state of the Collateral in any manner Lender may consider appropriate and the
Undersigned agrees to furnish all assistance and information and to perform all
such acts as Lender may request in connection therewith and for such purpose,
the Undersigned shall permit Lender and its representatives, from time to time,
and as often as may be requested, but only during normal business hours, to (i)
visit and inspect the properties at which any Collateral is located, (ii)
inspect, audit and make extracts from its books and records and (iii) discuss
with the Undersigned's officers, employees and

                                        9

<PAGE>   10



independent accountants, the Undersigned's business, assets, liabilities,
financial condition, business prospects and results of operations.

6.       SECURITIES.

         If Collateral at any time includes Securities, the Undersigned hereby
authorizes Lender to transfer the same or any part thereof into its own name or
that of its nominee(s) so that Lender or its nominee(s) may appear of record as
the sole registered owner thereof; provided, that, until the occurrence of Event
of Default, Lender shall deliver promptly to the Undersigned all notices or
other communications received by it or its nominee(s) as such registered owner
and, upon demand and receipt of payment of any reasonable expenses in connection
thereof, shall issue to the Undersigned or its order a proxy to vote and take
all action with respect to such Securities. After the occurrence of an Event of
Default, the Undersigned waives all rights to receive any notices or
communications received by Lender or its nominee(s) as such registered owner and
agrees that no proxy issued by Lender to the Undersigned or its order as
aforesaid shall thereafter be effective. Lender shall be entitled but not bound
or required to vote in respect of such Securities at any meeting at which the
holder thereof is entitled to vote and, generally, to exercise any of the rights
which the holder of such Securities may at any time have; provided, that, Lender
shall not be responsible for any loss occasioned by the exercise of any of such
rights or by the failure to exercise the same within the time limited for the
exercise thereof.

7.       COLLECTION AND VERIFICATION OF ACCOUNTS AND OTHER DEBTS.

         To expedite collection, the Undersigned shall endeavor to make
collection of its Accounts and all debts evidenced by its Chattel Paper or its
Instruments for Lender. Any of Lender's officers, employees or agents shall have
the right, at any time or times thereafter, in the name of Lender, any designee
of Lender or the Undersigned, to verify the validity, amount or any other matter
relating to any Account with the account debtor of such Account by mail,
telephone, telecopier or otherwise. The Undersigned shall cooperate fully with
Lender to facilitate and promptly conclude any such verification process.

8.       PROCEEDS, INCREASES, PROFITS, PAYMENTS OR DISTRIBUTIONS.

         Whether or not an Event of Default has occurred, Lender may take
control of or receive all proceeds of, income from or interest on Collateral and
may apply any money taken as Collateral to the satisfaction of the Obligations
secured hereby. Lender may hold as additional security any increase or profits
received from any Collateral in Lender's possession, may receive any payment or
distribution upon redemption or retirement of the Collateral or upon the
dissolution or liquidation of the issuer of the Collateral and may apply any
money received from such Collateral to reduce the Obligations secured hereby and
may hold any balance as additional security for such part of the Obligations as
may not yet be due, whether absolute or contingent. If the Undersigned receives
any such increase or profits or payments or distributions, the Undersigned will
deliver the same promptly to Lender to be held by Lender as herein provided.
Lender will not be obligated to keep any


                                       10

<PAGE>   11



Collateral separate or identifiable. In the case of any Instrument, Security or
Chattel Paper, Lender will not be obligated to take any necessary or other steps
to preserve rights against other persons.

9.       EVENT OF DEFAULT.

         The occurrence of one or more of the following events shall constitute
an "Event of Default":

         (a)      The Undersigned shall default in the payment of all or any
                  part of the Obligations of the Undersigned to Lender as the
                  same falls due, whether by acceleration or otherwise.

         (b)      The Undersigned shall default in the performance or observance
                  of any covenant, obligation, term, condition, undertaking,
                  provision or agreement heretofore, herein or hereafter given
                  to Lender, whether contained herein or in any other agreement
                  to which the Undersigned and Lender are parties, including,
                  without limiting the generality of the foregoing, any covenant
                  or undertaking set out in the Guaranty.

         (c)      Any of the representations and warranties heretofore, herein
                  or hereafter given to Lender is or becomes incorrect in any
                  respect at any time or any certificate, statement or audit
                  report heretofore, herein or hereafter given or delivered to
                  Lender is incorrect in any respect at the time such
                  certificate, statement or audit report is given or delivered
                  to Lender.

         (d)      If any execution, judgment or any other process of any court
                  shall become enforceable against the Undersigned or any
                  guarantor of any of the Obligations or any distress or
                  analogous process shall be levied upon the Collateral or any
                  part thereof.

         (e)      The Undersigned or any guarantor of any of the Obligations
                  shall become insolvent, file a bankruptcy petition, make an
                  assignment in bankruptcy, make a bulk sale of its assets or
                  otherwise transfer all or substantially all of its assets,
                  propose a compromise or arrangement to its creditors or take
                  advantage of provisions for relief under the U.S. Bankruptcy
                  Code or any other legislation for the benefit of insolvent
                  debtors.

         (f)      If a bankruptcy petition shall be filed or presented against
                  the Undersigned or any guarantor of any of the Obligations and
                  not be bona fide opposed by the Undersigned or any guarantor
                  of any of the Obligations, any proceeding is taken, whether in
                  court or under the terms of any agreement or appointment in
                  writing, with respect to a compromise or arrangement to have
                  the Undersigned or any guarantor of any of the Obligations
                  dissolved, liquidated or wound up, or to have a receiver or
                  similar official appointed in respect of the Undersigned or
                  any guarantor of any of the Obligations or of any part of the
                  Collateral, or if any encumbrance becomes


                                       11

<PAGE>   12



                  enforceable against any Collateral or any encumbrancer takes
                  possession of any part thereof.

         (g)      The Undersigned or any guarantor of any of the Obligations
                  shall cease or threaten to cease to carry on business for a
                  period which significantly affects the Undersigned's capacity
                  to continue its business, on a profitable basis; or the
                  Undersigned shall suffer the loss or revocation of any license
                  or permit now held or hereafter acquired by the Undersigned
                  which is necessary to the continued or lawful operation of its
                  business; or the Undersigned shall be enjoined, restrained or
                  in any way prevented by court, governmental or administrative
                  order from conducting all or any material part of its business
                  affairs.

         (h)      An Event of Default shall have occurred under (and as defined
                  in) the Loan and Security Agreement dated December 21, 1995,
                  between Lender and Borrower, as modified, amended or otherwise
                  altered (the "Loan Agreement").

         (i)      If the Undersigned enters into any reorganization, merger or
                  other similar arrangement.

         (j)      The Undersigned shall be criminally indicted or convicted
                  under any law that could lead to forfeiture of any property of
                  the Undersigned.

         (k)      Lender shall have commercially reasonable grounds to believe
                  that the prospect of payment of the Obligations or performance
                  of the obligations under this General Security Agreement or
                  under any other agreement between the Undersigned and Lender
                  are about to be impaired or that the Collateral is about to be
                  in danger of being lost, damaged, confiscated or placed in
                  jeopardy.

         (l)      The Undersigned or any other guarantor of all or any part of
                  the Obligations shall revoke or attempt to revoke its
                  guaranty.

The provisions of this clause are not intended in any way to affect any rights
of Lender with respect to any Obligations which may now or hereafter be payable
on demand.

10.      REMEDIES ON DEFAULT.

         (a)      Upon or at any time after the occurrence of any Event of
                  Default, Lender, at its sole discretion, may declare all or
                  any part of the Obligations, whether or not any such
                  Obligation is not by its terms payable on demand, to be
                  immediately due and payable in full, without demand or notice
                  of any kind.

         (b)      If Lender declares that the Obligations shall immediately

                  of the Obligations, take immediate possession of the
                  Collateral, enter upon any premises of the Undersigned,
                  otherwise enforce this General Security Agreement and enforce
                  any rights of the Undersigned in respect of the Collateral by
                  any manner permitted by applicable law, and may use the
                  Collateral in the manner and to the extent that Lender may
                  consider appropriate and may hold, insure, repair, process,
                  maintain, preserve, prepare for disposition and dispose of the
                  same and may require the Undersigned to assemble and deliver
                  the Collateral or make the Collateral available to Lender at a
                  place designated by Lender. Lender may also take proceedings
                  in any court of competent jurisdiction for the appointment of
                  a receiver (which term shall include a receiver and manager)
                  of the Collateral or of any part thereof or may by instrument
                  in writing appoint any person to be a receiver of the
                  Collateral or of any part thereof and may remove any receiver
                  so appointed by Lender and appoint another in his stead; and
                  any such receiver appointed by instrument in writing shall, to
                  the extent permitted by applicable law or to such lesser
                  extent permitted, have all of the rights, remedies, benefits
                  and powers of Lender hereunder or under the Code or otherwise
                  and, without limiting the generality of the foregoing, have
                  power (i) to take possession of the Collateral or any part
                  thereof, (ii) to carry on or concur in carrying on all or any
                  part or parts of the business of the Undersigned, (iii) to
                  file such proofs of claim and other documents as may be
                  necessary or advisable in order to have his claim lodged in
                  any bankruptcy, winding-up or other judicial proceedings
                  relative to the Undersigned, (iv) to borrow money required for
                  the seizure, repossession, retaking, repair, insurance,
                  maintenance, preservation, protection, collection, preparation
                  for disposition, disposition or realization of the Collateral
                  or any part thereof and for the enforcement of this General
                  Security Agreement or for the carrying on of the business of
                  the Undersigned on the security of the Collateral in priority
                  to the security interest created under this General Security
                  Agreement, and (v) to sell, lease or otherwise dispose of, or
                  concur in the sale, lease or other disposition of, the whole
                  or any part of the Collateral at public auction, by public
                  tender or by private sale, lease or other disposition, either
                  for cash or upon credit, at such time and upon such terms and
                  conditions as the receiver may determine, provided that if any
                  such disposition involves a deferred payment or payments,
                  Lender will not be accountable for and the Undersigned will
                  not be entitled to be credited with the proceeds of any such
                  disposition until the monies therefor are actually received.
                  Any such receiver shall for all purposes be deemed to be the
                  agent of the Undersigned. Lender may from time to time fix the
                  remuneration of such receiver. All moneys from time to time
                  received by such receiver shall be paid by him first in
                  discharge of the reasonable expenses of Lender incurred in
                  retaking, holding, repairing, processing and preparing for
                  disposition and disposing of the Collateral including, without
                  limitation, all rents, taxes, rates, insurance premiums and
                  outgoings affecting the Collateral, remuneration of the
                  receiver, such other amounts referred to in subparagraph 12(b)
                  hereof, costs of keeping in good standing any liens and
                  charges on the Collateral prior to the security constituted by
                  this General Security Agreement and any other reasonable
                  expenses

                                       13

                  incurred by Lender, and secondly in or toward payment of such
                  parts of the Obligations of the Undersigned to Lender in such
                  manner and order as Lender may in its sole discretion
                  determine, and any residue of such moneys so received shall be
                  paid to the Undersigned. Lender in appointing or refraining
                  from appointing such receiver shall not incur any liability to
                  the receiver, the Undersigned or otherwise and shall not in
                  any way be responsible for any misconduct or negligence of any
                  such receiver.

         (c)      In addition to the rights and remedies specifically provided
                  herein, Lender shall, upon the occurrence of an Event of
                  Default, have the rights and remedies of a secured party under
                  the Code and other applicable legislation and as otherwise
                  provided by applicable law.

         (d)      If the disposition of the Collateral fails to satisfy all of
                  the Obligations, the Undersigned shall be liable to pay for
                  any deficiency on demand.

         (e)      When required to do so by the Code, Lender shall give to the
                  Undersigned the written notice required by the Code of any
                  intended disposition of the Collateral by serving such notice
                  personally on the Undersigned or by mailing such notice by
                  registered mail to the last known address of the Undersigned
                  or by any other method authorized or permitted by the Code.

11.      ACCOUNTS.

         In addition to the remedies set out in paragraph 10 hereof, Lender may
collect, realize, sell or otherwise deal with the Accounts or any part thereof
in such manner, upon such terms and conditions and at such time or times after
the occurrence of an Event of Default as may seem to it advisable and without
notice to the Undersigned (except in the case of sale and then subject to
subparagraph 10(e) hereof). Lender shall not be liable or accountable for any
failure to collect, realize, sell or obtain payment of the Accounts or any part
thereof and shall not be bound to institute proceedings for the purpose of
collecting, realizing or obtaining payment of the same or for the purpose of
preserving any rights of Lender, the Undersigned or any other person, firm or
corporation in respect of the same. All moneys collected or received by the
Undersigned in respect of the Accounts shall be received as trustee for Lender
and shall be forthwith paid over to Lender. All moneys collected or received by
Lender in respect of the Accounts or other Collateral may be applied, after
deduction of the reasonable expenses of realization from the money collected and
subject to any applicable requirements of the Code, on account of such parts of
the Obligations of the Undersigned as to Lender deems best or in the discretion
of Lender may be released to the Undersigned, all without prejudice to the
liability of the Undersigned or Lender' right to hold and realize this security.

12.      CHARGES AND EXPENSES.

         (a)      Upon the Undersigned's failure to perform any of its duties
                  hereunder, Lender may, but shall not be obligated to, perform
                  any or all of such duties, without waiving any rights to
                  enforce this General Security Agreement, and the Undersigned
                  shall pay to Lender, forthwith upon written demand therefor,
                  an amount equal to the costs, fees and expenses incurred by
                  Lender in so doing (including, without limiting the generality
                  of the foregoing, costs, fees and expenses associated with
                  legal advice and services).

         (b)      Lender may charge on its own behalf and pay to others
                  reasonable sums for costs, fees and expenses incurred and for
                  services rendered (including, without limiting the generality
                  of the foregoing, legal advice and services) in or in
                  connection with seizing, repossessing, retaking, repairing,
                  insuring, realizing, disposing of, retaining or collecting the
                  Collateral or any part thereof, and such sums shall be a first
                  charge on the proceeds of such realization, disposition or
                  collection. Subject to any applicable requirements of the Code
                  and the provisions of paragraph 10 hereof, the proceeds of any
                  such disposition of any Collateral may be applied by Lender to
                  the payment of all such costs, fees and expenses and any
                  balance of such proceeds may be applied by Lender towards the
                  payment of the Obligations in such order of application as
                  Lender may from time to time determine.

         (c)      All of the above costs, fees and expenses and all amounts
                  borrowed on the security of the Collateral under paragraph 10
                  hereof shall bear interest at a rate equal to two percent
                  (2.0%) per annum above the Interest Rate (as such term is
                  defined in the Loan Agreement) then in effect under the Loan
                  Agreement and shall be Obligations under this General Security
                  Agreement.

13.      FURTHER ASSURANCES.

         The Undersigned shall from time to time forthwith on Lender's request
furnish further assurance of title to the Collateral and further security to
Lender and execute and deliver all such financing statements, further
assignments, documents and instruments, and do or make all such further acts,
matters and things as may be required by Lender with respect to the Collateral
or any part thereof or as may be required or desirable to give effect to the
purposes and provisions of this General Security Agreement, and the Undersigned
further covenants and agrees to pay all costs and expenses incurred in
connection therewith. The Undersigned hereby irrevocably constitutes and
appoints Lender the true and lawful attorney of the Undersigned, with full power
of substitution, to do, make, sign, execute and deliver on behalf of the
Undersigned all such statements, assignments, documents, instruments, acts,
matters and things, as the Undersigned has agreed by these presents to do, make,
sign, execute or deliver or as may be required by Lender to give effect to these
presents or in the exercise of the powers on Lender hereby conferred, with the
right to use the name of the Undersigned, whenever and wherever Lender may deem
it necessary or expedient to do so. The power of attorney granted herein may be
exercised in the name and on behalf of the successors or

                                       15

<PAGE>   16



assigns of the Undersigned. None of the powers hereby granted shall be revoked
by the bankruptcy of the Undersigned.

14.      DEALINGS BY LENDER.

         Lender may grant extensions of time, additional advances, renewals,
extensions and other indulgences, take and give up securities, accept
compositions, grant releases and discharges and otherwise deal with the
Undersigned, debtors of the Undersigned, sureties and others and with the
Collateral and other securities as Lender may see fit without prejudice to the
liability of the Undersigned or Lender's rights under this General Security
Agreement.

15.      GENERAL.

         The Undersigned and Lender further agree that:

         (a)      This General Security Agreement shall constitute and be a
                  continuing security agreement in every respect, shall not be
                  considered as satisfied or discharged by any intermediate
                  payment of all or any part of the Obligations and shall be in
                  addition to and not in substitution for any other security now
                  or hereafter held by Lender.

         (b)      Nothing in this General Security Agreement shall obligate
                  Lender to make any loan or accommodation to the Undersigned or
                  to grant, continue, renew or extend the time for payment or
                  satisfaction of the Obligations.

         (c)      Any failure by Lender to exercise any right set out in this
                  General Security Agreement shall not constitute a waiver
                  thereof. No remedy for the enforcement of the rights of Lender
                  hereunder shall be exclusive of or dependent on any other such
                  remedy but any one or more of such remedies may from time to
                  time be exercised in whole or in part, independently or in
                  combination.

         (d)      The security interests and liens created or provided for by
                  this General Security Agreement are intended to attach to
                  Collateral existing when this General Security Agreement is
                  signed by the Undersigned and delivered to Lender (or in the
                  case of property acquired subsequent thereto, immediately upon
                  the Undersigned acquiring any rights in such property). The
                  Undersigned acknowledges that it has received value and has
                  (or in the case of after acquired property, will have) rights
                  in the Collateral. The parties do not intend to postpone the
                  attachment of any security interest or lien created hereby.
                  For greater certainty, it is declared that any and all future
                  loans, advances or other value which Lender may in its
                  discretion make or extend to or for the account of the
                  Undersigned shall be secured by this General Security
                  Agreement.


                                       16

<PAGE>   17



         (e)      All rights of Lender hereunder shall be assignable and in any
                  action brought by an assignee to enforce such rights, the
                  Undersigned shall not assert against the assignee any claim or
                  defense which the Undersigned now has or may hereafter have
                  against Lender.

         (f)      This General Security Agreement shall inure to the benefit of
                  and be binding upon Lender and the Undersigned, their
                  successors and assigns.

         (g)      If the Collateral or any part thereof is being sold or
                  delivered to the Undersigned by Lender, title and ownership of
                  each part of the Collateral shall not pass to the Undersigned
                  but shall be and remain in Lender until all Obligations in
                  respect of each such part are paid or performed in full.

         (h)      If more than one person executes this General Security
                  Agreement, then obligations hereunder shall be joint and
                  several and the Obligations shall include those of all or any
                  one or more of them.

         (i)      This General Security Agreement may be executed in one or more
                  counterparts, each of which when so executed shall be deemed
                  to be an original and such counterparts together shall
                  constitute one and the same instrument. Any signature
                  delivered by a party by facsimile transmission shall be deemed
                  to be an original signature hereto.

         (j)      In this General Security Agreement words importing number
                  shall include the singular and the plural, words importing
                  gender shall include all genders and the word "person" shall
                  include all firms, corporations, trusts, partnerships and
                  other forms of association.

         (k)      The headings of the paragraphs hereof are inserted for
                  convenience of reference only and shall not affect the
                  interpretation or construction of this General Security
                  Agreement.

         (l)      Time shall be of the essence of this General Security
                  Agreement and of each and every part hereof.

         (m)      This General Security Agreement shall be deemed effective upon
                  Lender's acceptance thereof. This General Security Agreement
                  will be governed in all respects by the laws of the State of
                  Georgia.

         (n)      No modification of or amendment to this General Security
                  Agreement shall be valid or binding unless set forth in
                  writing and duly executed by the Undersigned and Lender and no
                  waiver of any breach of any term or provision of this General
                  Security Agreement shall be effective or binding unless made
                  in writing and signed by the

                                       17

<PAGE>   18



                  party purporting to give the same and, unless otherwise
                  provided, shall be limited to the specific breach waived.

         (o)      Any provision of this General Security Agreement, as amended
                  from time to time, which is prohibited or unenforceable in any
                  jurisdiction shall, as to such jurisdiction, be ineffective to
                  the extent of such prohibition or unenforceability without
                  invalidation of the remaining provisions hereof or affecting
                  the validity or enforceability of such provision in any other
                  jurisdiction.
