         SECTION 201. THE LOANS. (a) From time to time upon Borrower's  request,
and subject to the terms and  conditions  of this  Agreement,  Lender  agrees to
advance to Borrower  prior to the Credit  Expiration  Date amounts  which do not
exceed the Maximum Availability in aggregate outstanding principal amount at any
one time.  Advances  made by Lender  to  Borrower  under  this  Section  201 are
hereinafter  collectively called the "Loans".  Notwithstanding  anything in this
Agreement to the contrary,  the Lender shall not be obligated  hereunder to make
any Loans on or after the  earlier  of (i) the  Credit  Expiration  Date or such
later  date to which  such  expiration  date may be  extended  by  Lender in its
discretion or (ii) the date Lender pursuant to Section 801(a) hereof  terminates
its obligation to make any further Loans to Borrower  hereunder.  Subject to the
terms and conditions hereof, prior to the Credit Expiration Date,  Borrower,  at
its option, from time to time may borrow,  repay and reborrow all or any portion
of the Loans,  except that  Borrower's  right to prepay Loans  bearing  interest
based on the  Adjusted  LIBOR (as such  term is  defined  in the Note)  shall be
subject to the breakage  provisions of the Note and any such prepayment shall be
applied as provided in the Note.

         (b) The  proceeds of the Loans may be used by Borrower  only to finance
acquisitions  by the Borrower and to finance  Borrower's  and its  Subsidiaries'
working capital



379000.1


                                       -8-





and other general corporate needs (including  without  limitation to finance the
cost of the leasehold improvements and equipment purchases made or to be made by
Borrower for its new corporate headquarters building in Marietta, Georgia).

         (c) The Loans are to be  evidenced  by the Note.  Interest on the Loans
will accrue at the rate or rates per annum set forth in the Note,  and principal
and interest on the Loans will be payable in the manner prescribed in the Note.

         (d)  Borrower  shall  pay to  Lender  an  origination  fee for the Loan
facility  provided by Lender to Borrower under this Section 201, which fee shall
be in the amount of $5,000 (and Lender shall credit  against such sum the $5,000
commitment  letter fee previously  paid by Borrower to Lender in connection with
such  facility)  and such fee shall be deemed  fully  earned by Lender  upon the
parties' execution and delivery of this Agreement from the Borrower and shall be
non-refundable.

         (e) Borrower  shall pay to Lender unused  facility fees for  Borrower's
Loan facility  hereunder  during the Revolving Loan Period computed on the daily
average  unused  portion  of the  Maximum  Availability  at a rate per  annum of
three-eighths of one percent (.375%). Such unused facility fees shall be payable
by Borrower to Lender quarterly in arrears, commencing on November 30, 1996, and
continuing to be due on the last day of each February,  May, August and November
thereafter  during the Revolving Loan Period as well as on the Credit Expiration
Date.  Notwithstanding  anything in this Section to the contrary,  however,  the
total unused  facility  fees payable by Borrower to Lender under clauses (x) and
(y) above shall not exceed the sum of $6,250 and $25,000,  respectively,  during
each of the  following two periods:  the period from the date of this  Agreement
though August 31, 1997, and the period from September 1, 1997 through the Credit
Expiration Date.

         (f) All of the Loans shall  constitute  one loan by Lender to Borrower.
Lender shall maintain a loan account on its books in which shall be recorded all
Loans,  all  payments  made by Borrower  on the Loans and all other  appropriate
debits and  credits as  provided  in this  Agreement  and the Note with  respect
thereto,  including without limitation all charges,  expenses and interests. All
entries in such account shall be made in accordance with the Lender's  customary
accounting  practices  as in effect from time to time.  Lender  shall  render to
Borrower  a  monthly  statement  setting  forth  the  balance  of such  account,
including principal, interest, expenses and fees, and each such statement shall,
absence  manifest  error or  omissions,  be presumed  correct  and binding  upon
Borrower and shall constitute an account stated unless,  within thirty (30) days
after  receipt of any such  statement  from Lender,  Borrower  shall  deliver to
Lender a written objection thereto specifying the error or errors or omission or
omissions, if any, contained in such statement.

         (g) All  interest  and fees owing by  Borrower to Lender  hereunder  or
under the other Financing  Documents shall be computed on the basis of a 360-day
year and the actual days elapsed

         SECTION 202.  COLLATERAL AND  GUARANTIES.  (a) All of the Loans and the
other  Liabilities  shall be secured  pursuant to the Security  Agreement  which

this  Agreement  and pursuant to which Lender shall be granted a  first-priority
security  interest in all of  Borrower's  present or future  accounts,  contract
rights,  chattel paper, general intangibles (excluding its Intellectual Property
Rights but including the proceeds thereof),  instruments,  documents, inventory,
equipment,  fixtures, leasehold improvements,  and other assets and all proceeds
thereof  (excluding its Intellectual  Property Rights but including the proceeds
thereof). In addition,  all of the Loans and the other Liabilities shall also be
secured pursuant to a Stock Pledge Agreement which (together with an irrevocable
stock power in the form of Exhibit C-2 attached  hereto)  shall be duly executed
and  delivered  by  Borrower to Lender in  connection  with this  Agreement  and
pursuant to which Lender shall be granted a first-priority  security interest in
all of the capital stock of CryoLife International and all proceeds thereof.

         (b)  All  of the  Loans  and  the  other  Liabilities  shall  be  fully
guaranteed by CryoLife  International  pursuant to a Subsidiary  Guaranty  which
shall be duly  executed  and  delivered by CryoLife  International  to Lender in
connection  with this  Agreement.  In  addition,  the  obligations  of  CryoLife
International  under such  Subsidiary  Guaranty  shall be secured  pursuant to a
Subsidiary  Security  Agreement  which shall be duly  executed and  delivered by
CryoLife International to Lender in connection with this Agreement, and pursuant
to which Lender shall be granted a  first-priority  security  interest in all of
CryoLife  International's  present or future accounts,  contract rights, chattel
paper,  general  intangibles  (excluding its  Intellectual  Property  Rights but
including the proceeds thereof),  instruments,  documents, inventory, equipment,
fixtures, leasehold improvements, and other assets and all proceed thereof.

         (c) Within ten (10) days after  Borrower's  creation or  acquisition of
any  Subsidiary,  Borrower  shall  pledge  all  of the  capital  stock  of  such
Subsidiary to the Lender as additional collateral for the Liabilities,  Borrower
shall cause such  Subsidiary  to guaranty the  repayment of the  Liabilities  to
Lender,  and  Borrower  shall  cause  such  Subsidiary  to grant to the Lender a
first-priority  perfected  security  interest  in and lien on all of its  assets
(excluding its Intellectual Property Rights, but including the proceeds thereof)
as additional  collateral for the  Liabilities,  all pursuant to such Subsidiary
Guaranties,  Subsidiary Security  Agreements,  Stock Pledge Agreements and other
collateral  documents as are acceptable in all respects to the Lender.  Borrower
also shall  provide  Lender  with any and all  closing  certificates,  financing
statement filings,  opinions of counsel and other closing documents of the types
described  in Section 605 hereof as the Lender may request  with respect to such
pledge, guaranty and collateral documents.

         (d)  Borrower  shall  execute  (or  cause to be  executed)  any and all
financing  statements,  fixture  filings,  certificate  of  title  applications,
collateral assignments,  stock powers or transfers, or other documents as Lender
may  reasonably  request  from time to time in order to perfect or maintain  the
perfection and priority of Lender's  security  interest in the Collateral now or
hereafter covered by the Security  Agreement,  any Stock Pledge Agreement or any
Subsidiary Security Agreement or any additional collateral documents executed by



379000.1


                                      -10-





Borrower or any Subsidiary pursuant to this Section 202.

         (e) If any of the Collateral  will be located on any premises which are
leased by  Borrower  or any of its  Subsidiaries  from a third party or, if such
premises are owned by Borrower or one of its Subsidiaries, on which any creditor
(other than Lender) holds a security deed, mortgage, or deed of trust granted by
Borrower or one of its Subsidiaries,  Borrower shall cause each such third party
lessor or  creditor  to  execute  in favor of  Lender a Waiver  and  Consent  in
substantially  the form of Exhibit I  attached  hereto (or in such other form as
may be acceptable to Lender).

         SECTION 203. AGREEMENTS REGARDING INTEREST AND OTHER CHARGES.  Pursuant
to the Official Code of Georgia  Annotated  Section  7-4-2,  Lender and Borrower
hereby  agree that the only  charge  imposed  or to be  imposed  by Lender  upon
Borrower  for the use of money in  connection  with the Loans is and will be the
interest  required under the Note, which interest will be at the rates which are
or will be expressed in simple interest terms in the Note as of the date of such
Note.  Borrower hereby acknowledges and agrees that Lender has not imposed on it
any minimum borrowing requirements,  reserve or escrow balances, or compensating
balances  related in any way to this Agreement.  In no event shall the amount of
interest  due and  payable  under this  Agreement,  the Note or any of the other
Financing  Documents  exceed the maximum rate of interest  allowed by applicable
law (including,  without limitation,  Official Code of Georgia Annotated Section
7-4-18) and, in the event any such payment is inadvertently  made by Borrower or
inadvertently received by Lender, such excess sum shall be credited as a payment
of principal.  It is the express  intent hereof that Borrower not pay and Lender
not receive, directly or indirectly or in any manner, interest in excess of that
which may be lawfully paid under applicable law.

         SECTION 204. INDEMNITY.  Borrower agrees to indemnify and hold harmless
the Lender from and against any and all claims,  liabilities,  losses,  damages,
actions and demands by any party  against the Lender  arising out of the making,
holding or  administration  of the Loans or the  Collateral,  allegations of any
participation  by the Lender in the affairs of any or all of the Credit  Parties
or  allegations  that the Lender has any joint  liability with any or all of the
Credit  Parties  for  any  reason,  or any  claims  against  the  Lender  by any
shareholder of the Borrower,  unless,  with respect to the above,  the Lender is
finally  and  judicially  determined  to have  acted or failed to act with gross
negligence or to have engaged in willful misconduct.

         SECTION 205. CAPITAL ADEQUACY. Without limiting any other provisions of
this Agreement,  in the event that the Lender  determines  after the date hereof
that the  introduction  or change  after the date of this  Agreement of any law,
treaty,  governmental (or  quasi-governmental)  rule,  regulation,  guideline or
order regarding capital adequacy, or any change therein or in the interpretation
or application  thereof after the date of this  Agreement,  or compliance by the
Lender with any request or directive  regarding capital adequacy (whether or not
having the force of law and whether or not failure to comply  therewith would be
unlawful)  from  a  central  bank  or  governmental  authority  or  body  having
jurisdiction  which is introduced  or changed after the date of this  Agreement,
does or shall



379000.1


                                      -11-





have the  effect of  reducing  the rate of return on the  Lender's  capital as a
consequence of its obligations  hereunder to a level below that which the Lender
could have achieved but for such law,  treaty,  rule,  regulation,  guideline or
order or such change or  compliance  (taking  into  consideration  the  Lender's
policies with respect to capital  adequacy and assuming the full  utilization of
the Lender's capital immediately before such adoption,  change or compliance) by
an amount reasonably deemed by the Lender to be material,  then the Lender shall
promptly after its determination of such occurrence notify the Borrower thereof.
The Borrower agrees to pay to the Lender as an additional fee from time to time,
within ten (10) days after written notice and demand by the Lender,  such amount
as the  Lender  certifies  to be the  amount  that will  compensate  it for such
reduction in connection  with its  obligations  hereunder.  A certificate of the
Lender  claiming  compensation  under this Section  shall be  conclusive  in the
absence  of  manifest  error or fraud and  shall  set  forth  the  nature of the
occurrence giving rise to such compensation, the additional amount or amounts to
be paid to it hereunder and the method by which such amounts were determined. In
determining such amount, the Lender may use reasonable averaging and attribution
methods.

                  ARTICLE III - REPRESENTATIONS AND WARRANTIES

or by  which  it or any of its  properties  or  assets  is  bound  or  affected.
Execution, delivery and performance by any Credit Party of each and every of the
Financing  Documents  executed  by it do not  violate  any  provision  of law or
regulations and does not result in a breach of or constitute a default under any
agreement, indenture or other instrument to which any Credit Party is a party or

decree of any court pending, anticipated or (to Borrower's knowledge) threatened
against any Credit Party or against any of its  properties or assets which might
have a material  adverse  effect on the Credit Parties taken as a whole or their
respective  properties or assets, or which might call into question the validity
or enforceability of any of the Financing Documents,  or which might involve the
alleged violation by any Credit Party of any federal, state, local or other law,
rule or regulation;  provided,  however,  that no representation is made in this
Section 305 with respect to Environmental Laws.

state,  local,  or other  securities  laws and  regulations  with respect to the
issuance of any of its capital stock or any other of its securities.

         SECTION 308.  TAX RETURNS.  Each Credit Party has filed or caused to be

basis of any material claim, action, demand, suit, proceeding, hearing, study or

pursuant to this  Agreement  shall  constitute an automatic  representation  and
warranty  by  Borrower  to Lender  that there does not then exist any Default or
Event of Default as well as a  reaffirmation  as of the date of such  request of
all of the  representations  and warranties of the Credit  Parties  contained in

                       ARTICLE IV - AFFIRMATIVE COVENANTS

         For so long as this Agreement is in effect, and unless Lender expressly
consents in writing  otherwise or to the contrary  (which  consent  shall not be
unreasonably  withheld),  Borrower  hereby  expressly  covenants  and  agrees as
follows:

         SECTION 401.  INSPECTION AND  EXAMINATION.  Upon reasonable  request of
Lender,  each Credit Party shall permit during regular business hours any person
designated by Lender to inspect and examine such Credit Party's  financial books
and  records,  its  minute  books and other  business  memoranda  and  writings;
provided,  however, that so long as no Event of Default has occurred and is then
continuing  Borrower may condition  Lender's (or its  designee's)  access to any
Credit Party's  business  memoranda and writings (other than its financial books
and records) on Lender's (or such  designee's)  entering into a suitable written
confidentiality  agreement.  Each Credit Party shall make available its officers
and employees to Lender to discuss the financial affairs of such Credit Party at
such reasonable times and intervals as Lender may request, and each Credit Party
shall  promptly  confirm or furnish in reasonable  detail  whatever  information
relative to such Credit Party as Lender's authorized representative,  auditor or
counsel may reasonably request.

         SECTION 402. BOOKS AND RECORDS. Each Credit Party shall keep its books,
records and accounts in accordance with generally accepted accounting principles
and practices applied on a basis consistent with preceding years.

subsequent fiscal year,  consolidated and consolidating  financial statements of

by a duly  completed  Compliance  Certificate  in the form of Exhibit J attached
hereto  executed on behalf of Borrower by its chief financial  officer;  (2) Not

month of each fiscal year),  consolidated  financial statements of Borrower,  to
include balance sheets and statements of income and stockholders' equity, all in
reasonable  detail,  prepared in accordance with generally  accepted  accounting
principles  (subject  to  changes  resulting  from  year-end  adjustments),  and
certified by the chief  financial  officer of Borrower and accompanied by a duly
completed  Compliance  Certificate  in the form of  Exhibit  J  attached  hereto
executed on behalf of Borrower by its chief financial officer; (3) Promptly upon
becoming  aware of the  existence of any Default or Event of Default,  a written
notice  specifying  the nature and period of  existence  thereof and what action
Borrower is taking or proposes to take with respect  thereto;  (4) Promptly upon
becoming aware that the holder of any other evidence of indebtedness or security
of any Credit Party has given notice or taken any other action with respect to a
claimed default or event of default or event which, with the giving of notice or
passage  of time,  or  both,  would  constitute  a  default,  a  written  notice
specifying the notice given or action taken by such holder and the nature of the
claimed  default or event and what action Borrower is taking or proposes to take
with respect  thereto;  (5) Promptly upon  transmission  thereof,  copies of all
financial  statements,  proxy statements,  notices and reports as Borrower shall
send  to its  public  shareholders,  if  any,  and  copies  of all  registration
statements  and all other reports which Borrower may file from time to time with
the  Securities  and Exchange  Commission  or any  comparable  state  securities
regulatory agency; and (6) From time to time upon request of Lender,  such other
information relating to the operations, business, and financial condition of any
Credit Party as Lender may reasonably request.

         SECTION 404.  MAINTENANCE  OF ASSETS.  Each Credit Party shall maintain
and keep all of its  property  and assets  (other than Tissue  Freezers) in good
repair, working order and condition and shall from time to time make all needful
and proper repairs, renewals and replacements thereto subject to reasonable wear
and tear.

         SECTION 405. MAINTENANCE OF INSURANCE. Each Credit Party shall maintain
with  financially  sound and  reputable  insurers  acceptable to Lender (i) with
reference  to its property  other than the  Collateral,  insurance  against such
risks and in such amounts as is customary in the case of Persons of  established
reputations engaged in the same or similar business and similarly situated,  and
(ii)  liability  and  worker's  compensation  insurance  in such  amounts  as is
customary in the case of Persons of established  reputations engaged in the same
or similar  business and  similarly  situated  (except that the dollar amount of
each Credit Party's liability  insurance coverage must be acceptable to Lender),
and, upon request by Lender,  shall furnish  Lender copies of the policies under
which such  insurance is carried.  The Credit  Parties'  obligations  concerning
insurance of the Collateral are governed by the applicable  Financing Documents.
The Credit  Parties  shall not be  required to maintain  property  insurance  on
Tissue Freezers.

         SECTION 406.  PAYMENT OF TAXES.  Each Credit Party shall punctually pay
and discharge all taxes,  assessments and governmental charges or levies imposed
upon it or



379000.1


                                      -16-





upon its income or upon any of its  property,  as well as all claims of any kind
which,  if unpaid,  might by law become a Lien upon its property,  except taxes,
assessments,  charges,  levies or claims  which are in good faith  being  timely
litigated or otherwise  properly contested by such Credit Party and which cannot
become a Lien  upon  any of the  Collateral  with  priority  over  the  security
interest of Lender or as to which such  Credit  Party has  established  reserves
satisfactory  to Lender.  Upon any Credit Party's failure to make prompt payment
of any such obligation of such Credit Party not excepted above,  Lender may, but
is  under  no  obligation  to,  pay all or any  part of the  same  or  effect  a
settlement  or  compromise  thereof in the name of such  Credit  Party;  and all
amounts so paid by Lender as well as the  expenses  incurred in  negotiating  or
attempting to negotiate a compromise or settlement will  automatically  become a
part of the  Liabilities of Borrower under this Agreement and will bear interest
from the date of such  payment at the lower of (i) the highest  rate of interest
which  Borrower  has  contracted  to pay on any of the  Liabilities  or (ii) the
highest rate permissible under applicable law.

         SECTION 407.  ENVIRONMENTAL  MATTERS.  Borrower  shall notify Lender in
writing, promptly upon learning thereof, of:

         (i) any  notice  that  any  Credit  Party is not in  compliance  in any
material  respect with all terms and  conditions  of all  permits,  licenses and
authorizations  which are required under  Environmental Laws, or that any Credit
Party is not in compliance in any material  respect with all other  limitations,
restrictions,  conditions, standards, prohibitions,  requirements,  obligations,
schedules and timetables contained in any applicable Environmental Laws;

         (ii) any  notice of any past,  present  or future  events,  conditions,
circumstances,  activities,  practices,  incidents, actions or plans which, with
respect to any Credit  Party,  may interfere  with or prevent its  compliance or
continued  compliance in any material  respect with  Environmental  Laws, or may
give  rise to any  material  common  law or  legal  liability  on its  part,  or
otherwise  form  the  basis  of  any  material  claim,  action,   demand,  suit,
proceeding,  hearing,  study or investigation against it, based on or related to
the manufacture,  processing,  distribution,  use, treatment, storage, disposal,
transport,  or  handling,  or the  emission,  discharge,  release or  threatened
release  into the  environment,  of any  pollutant,  contaminant,  chemical,  or
industrial, toxic or hazardous substance or waste; and

         (iii) any  notice or claim of any  civil,  criminal  or  administrative
action,  suit,  demand,  claim,  hearing,  notice  or demand  letter,  notice of
violation, investigation, or proceeding pending or threatened against any Credit
Party relating in any way to Environmental Laws.

         SECTION 408. PRIMARY  DEPOSITORY  RELATIONSHIPS.  To the maximum extent
permitted by applicable  law, the Credit  Parties shall  maintain  their primary
depository relationships with Lender.

without  presentment,  demand,  notice or  protest of any kind (all of which are
expressly  waived by Borrower in this  Agreement),  be declared due and payable,
whereupon they immediately will become due and payable;

         (c) Lender may also, at its option, and without notice or demand of any
kind, exercise from time to time any and all rights and remedies available to it
under this



379000.1


                                      -23-





Agreement  or under any of the other  Financing  Documents,  as well as exercise
from time to time any and all rights and remedies  available to a secured  party
when a debtor is in  default  under a  security  agreement  as  provided  in the
Uniform  Commercial  Code of Georgia,  or  available  to Lender  under any other
applicable  law or in  equity,  including  without  limitation  the right to any
deficiency remaining after disposition of the Collateral; and

         (d)  Borrower  shall  pay  all of the  reasonable  costs  and  expenses
actually incurred by Lender in enforcing its rights under this Agreement and the
other Financing Documents.  In the event any claim under this Agreement or under
any of the other Financing  Documents is referred to an attorney for collection,
or collected by or through an attorney at law, Borrower will be liable to Lender
for all reasonable  expenses  actually  incurred by it in seeking to collect the
Liabilities or to enforce its rights hereunder, in the other Financing Documents
or in  the  Collateral,  including  without  limitation  actual  and  reasonable
attorneys' fees.

         SECTION 802.  APPLICATION OF PROCEEDS;  COLLECTION  COSTS. Any proceeds
from  disposition of any of the Collateral may be applied by Lender first to the
payment of all  reasonable  expenses  and costs  actually  incurred by Lender in
collecting  such  Liabilities,  in enforcing the rights of Lender under each and
every of the  Financing  Documents  and in  collecting,  retaking,  holding  and
preparing the Collateral for and  advertising  the sale or other  disposition of
and realizing upon the Collateral,  including without  limitation the reasonable
expenses of  liquidating  any liens or claims upon the Collateral and reasonable
attorneys'  fees (but not to exceed  actual fees  incurred) as well as all other
legal  expenses and court costs.  Any balance of such proceeds may be applied by
Lender  toward  the  payment  of such of the  Liabilities  and in such  order of
application  as the Lender  may from time to time  elect.  Lender  shall pay the
surplus,  if any, to Borrower.  Borrower  shall pay the  deficiency,  if any, to
Lender.

                           ARTICLE IX - MISCELLANEOUS

         SECTION 901. TIME OF ESSENCE. Time is of the essence of this Agreement.

         SECTION 902. ENTIRE AGREEMENT.  This Agreement,  together with the Note
and all of the other Financing Documents, supersedes and replaces the Prior Loan
Agreements,  the Prior Security Agreements,  and all other prior discussions and
agreements  by and between any of the Credit  Parties and Lender with respect to
the Loans or the  Collateral,  and together they  constitute the sole and entire
agreement  between the parties with  respect  thereto.  No promises,  covenants,
representations,  or  agreements  other  than  as  expressly  set  forth  in the
Financing  Documents  have been made to or with any Credit  Party,  and Borrower
represents  and  warrants  that it is not  relying on any  promises,  covenants,
representations  or  agreements,  other  than as  expressly  set  forth  in such
documents in entering into this Agreement.

         SECTION 903.  SEVERAL  COUNTERPARTS.  This Agreement may be executed in
any number of counterparts each of which shall be deemed an original, and all of
such



379000.1


                                      -24-





counterparts together shall constitute one and the same instrument.

         SECTION 904. SURVIVAL OF WARRANTIES.  All  representations,  covenants,
and  warranties  made  in  this  Agreement,  or in any of  the  other  Financing
Documents are cumulative and in addition to those imposed by law or equity,  and
are to survive the execution  hereof,  the making of the Loans, and the delivery
hereof and of all the other Financing Documents.

         SECTION  905.  RIGHTS  CUMULATIVE.  All rights and  remedies of Lender,
whether  provided  for  herein or in any of the  other  Financing  Documents  or
conferred by law or in equity or by statute or otherwise, are cumulative and not
alternative,  and may be enforced successively or concurrently.  The collection,
repossession,  sale or retention of any of the Collateral by Lender will not bar
an action by Lender for the  recovery of any of the  Liabilities  of Borrower to
Lender  (Borrower  having expressly agreed herein to remain fully liable for any
deficiency), nor will Lender's bringing of an action against Borrower to recover
moneys  owing  under any of the  Liabilities  bar  Lender's  right to collect or
repossess any of the Collateral.

         SECTION  906.  NO  RELEASE;  TERM OF  AGREEMENT.  No sale,  assignment,
transfer,   renewal,   addition,    extension,    consolidation,    subdivision,
modification,  or  substitution  of  any of  the  Liabilities,  or of any of the
Financing  Documents,  or of any  interest  thereunder,  nor any  loss,  damage,
injury,  theft,  or destruction of any of the Collateral  will release  Borrower
from its  obligations  hereunder.  The Liabilities may from time to time be paid
and Liabilities thereafter incurred, and neither this Agreement nor the security
interests and security titles conveyed under the Financing Documents shall lapse
or terminate because no Liabilities are outstanding. This Agreement shall remain
in full force and effect until such time as (i) no Liabilities  are  outstanding
and (ii) Lender is under no obligation to make any Loans hereunder to Borrower.

         SECTION 907. WAIVERS AND MODIFICATIONS.  Lender will not be deemed as a
consequence of any act,  delay,  failure,  omission,  or forbearance  (including
without limitation failure to exercise its right of accelerating the maturity of
any of the Liabilities or other indulgences granted from time to time by Lender)
or for any other reason:  (1) to have waived, or to be estopped from exercising,
any of its rights or  remedies  under this  Agreement  or under any of the other
Financing  Documents,  or (2) to have modified,  changed,  amended,  terminated,
rescinded,  or  superseded  any of the terms of this  Agreement or of any of the
other Financing Documents, unless such waiver, modification,  amendment, change,
termination,  rescission, or supersession is express, in writing and signed by a
duly authorized  officer of Lender.  No single or partial  exercise by Lender of
any right or remedy will preclude other or further  exercise thereof or preclude
the  exercise  of any other  right or  remedy,  and a waiver  expressly  made in
writing on one occasion  will be effective  only in that  specific  instance and
only for the precise  purpose for which  given,  and will not be  construed as a
consent to or a waiver of any right or remedy on any future occasion.  No notice
to or demand on Borrower in any instance  will entitle  Borrower to any other or
future notice or demand in similar or other circumstances.



379000.1


                                      -25-






         SECTION 908. WAIVER OF  PRESENTMENT,  ETC.  Borrower  hereby  expressly
waives presentment,  demand,  dishonor,  protest,  notice for payment, notice of
non-payment,  notice of dishonor,  notice of default,  notice of  compromises or
surrender  and any other  demand or notice  whatsoever  in  connection  with the
Financing Documents.

         SECTION 909. NOTICES.  Except as provided  otherwise in this Agreement,
all notices and other  communications  under this Agreement are to be in writing
and are to be deemed to have been duly given and to be effective  upon  delivery
to the party to whom  they are  directed.  If sent by U.S.  mail,  first  class,
certified, return receipt requested, postage prepaid, and addressed to Lender or
to Borrower at their  respective  addresses set forth  beneath their  respective
signatures  below,  such  notices,  demands and other  communications  are to be
deemed to have been delivered on the second  business day after being so posted.
Either  Lender or  Borrower  may by  written  notice to the  other  designate  a
different address for receiving notices under this Agreement; provided, however,
that no such change of address will be effective until written notice thereof is
actually received by the party to whom such change of address is sent.

         SECTION 910. NO ASSIGNMENT BY BORROWER.  Borrower may not,  without the
consent of Lender,  assign any of its rights or duties hereunder or under any of
the other Financing Documents.

         SECTION 911. LENDER'S EXPENSES. All statements,  reports, certificates,
opinions,  and other  documents  or  information  furnished  to Lender under the
Financing  Documents  shall be  supplied  by  Borrower  without  cost to Lender.
Further,   Borrower  shall  reimburse   Lender  on  demand  for  all  reasonable
out-of-pocket  costs and expenses  (including  actual and reasonable legal fees)
incurred by the Lender or its  participants in connection with the  preparation,
establishment,   operation,   enforcement,  and  termination  of  the  Financing
Documents or the protection or  preservation of any right or claim of the Lender
with respect to the Financing  Documents;  provided,  however,  that  Borrower's
obligation to reimburse Lender for its attorney's fees and expenses  relating to
the  initial  preparation  and  establishment  of this  Agreement  and the other
Financing Documents shall not exceed $10,000.

         SECTION 912. PAYMENT OF TAXES.  Borrower will pay all taxes (if any) in
connection with this Agreement,  any of the other Financing Documents, any loans
made in connection with this  Agreement,  or the issuance or ownership of any of
the Financing  Documents and in connection with any  modification of said loans,
this Agreement, or any of the other Financing Documents (excluding, however, any
taxes  imposed upon or measured by the net income of the Lender),  and will save
the  Lender  harmless  without  limitation  as  to  time  against  any  and  all
liabilities  with respect to all such taxes.  The  obligations of Borrower under
this section shall survive the payment of the Liabilities and the termination of
this Agreement.

         SECTION 913. DEMAND LIABILITIES. If any of the Liabilities are by their
terms demand  obligations,  nothing  contained  herein shall  affect,  impair or
modify the



379000.1


                                      -26-





demand nature of such  obligations,  and the occurrence of a Default or an Event
of Default shall not be a prerequisite  for Lender's  requiring  payment of such
obligations.

         SECTION 914. SET-OFFS AGAINST DEPOSITS. Upon the occurrence of an Event
of Default hereunder, Lender, without notice or demand of any kind, may hold and
set off against such of the Liabilities (whether matured or unmatured) as Lender
may  elect,  any  balance or amount to the credit of  Borrower  in any  deposit,
agency,  reserve,  holdback or other account of any nature whatsoever maintained
by or on behalf of Borrower  with Lender at any of its  offices,  regardless  of
whether  such  accounts  are general or special and  regardless  of whether such
accounts are individual or joint.

         SECTION 915.  PARTICIPANT SET-OFF. Any Person purchasing an interest in
debt obligations  under this Agreement held by Lender may exercise all rights of
offset with respect to such interest as fully as if such Person were a holder of
debt obligations hereunder in the amount of such interest.

         SECTION  916.  CONFIDENTIALITY.  Each of the parties to this  Agreement
shall use  reasonable,  good  faith  efforts to  maintain  as  confidential,  in
accordance with such Person's  normal  practices and policies for protecting its
own confidential  information,  this Agreement and the other Financing Documents
and the terms and conditions  thereof,  and all other  information  delivered to
such party in  connection  with the  transactions  contemplated  by or otherwise
pursuant to this  Agreement  that is  proprietary in nature and that was clearly
marked or labeled or otherwise  identified  as being  confidential  information;
provided, however, that each such Person may disclose information concerning the
aforesaid  Financing  Documents  or their  terms and  conditions  or such  other
confidential  information  described  above  (i) as  required  in its  counsel's
opinion  pursuant to the lawful  requirements  or  requests of any  Governmental
Authority,  (ii) as required in its  counsel's  opinion by any  governmental  or
administrative  rule,  judicial  process or subpoena,  (iii) to their respective
attorneys,  accountants,  advisers or  consultants  (but only on a  confidential
basis as provided below),  (iv) to the extent necessary in its counsel's opinion
to enforce such Person's rights or remedies or perform such Person's obligations
under any of the  Financing  Documents  or  applicable  law,  (v) to the  extent
necessary or  appropriate  in the opinion of its counsel in connection  with any
litigation  or other  proceeding  having it or any of its  Affiliates as a party
thereto,  and (vi)  Lender  may  disclose  such  information  to any  actual  or
prospective  assignee or  participant  of Lender.  If Lender or any Credit Party
discloses any  information  covered by this  subsection to any of its attorneys,
accountants,  advisers or consultants,  such Person shall advise such attorneys,
accountants,  advisers or consultants of the provisions of this Section but such
Person  shall  not  be  liable  for  any  misappropriation  or  misuse  of  such
information by such attorneys,  accountants,  consultants or advisers other than
occasioned by such  Person's own gross  negligence  or willful  misconduct.  The
obligations  of the parties  under this Section 916 shall survive until one year
after the date of any termination of this Agreement. Lender agrees, upon request
of Borrower  following any  termination  of this  Agreement,  to use  reasonable
efforts to return to Borrower any  confidential  or  proprietary  information of
Borrower  delivered  to  Lender  pursuant  to  this  Agreement  and in  Lender's
possession.

         SECTION 917. GOVERNING LAW; SEVERABILITY. This Agreement and all of the
other Financing  Documents have been made and delivered in the State of Georgia,
and the terms, provisions and performance thereof are in all respects, including

to the  extent of such  prohibition  or  invalidity,  without  invalidating  the
remainder of such provision or the remaining  provisions of this Agreement or of
any of the other Financing Documents.

Financing  Documents  shall inure to the benefit of its  successors and assigns.

                                 PROMISSORY NOTE


AUGUST 30, 1996                                                      $10,000,000

     FOR VALUE RECEIVED, the undersigned (hereinafter referred to as "Borrower")
promises to pay to the order of NATIONSBANK,  N.A. (SOUTH) (hereinafter referred
to as  "Lender")  at Lender's  office  located at 600  Peachtree  Street,  N.E.,
Atlanta,  Georgia  30308,  or at such  other  place  as the  holder  hereof  may
designate,  the principal sum of TEN MILLION DOLLARS  ($10,000,000),  or so much
thereof  as shall  have been  advanced  hereagainst  and  shall be  outstanding,
together with  interest on so much of the principal  balance of this Note as may
be  outstanding  and  unpaid  from  time to time,  calculated  on the basis of a
360-day year and actual days  elapsed,  at the rate or rates per annum  provided
below.

     The unpaid principal balance of this Note shall bear interest at a rate per
annum equal to the Prime Rate (as defined below) plus (i) zero basis points (0%)
during the period from the date of this Note through  August 31, 2001,  and (ii)
twenty-five  basis points  (0.25%) from and after  September 1, 2001;  provided,
however,  that  Borrower  may,  by a written  notice  (or by  telephonic  notice
promptly confirmed in writing) delivered to the Lender not later than 10:00 a.m.
(Atlanta  time) on the  second  Business  Day prior to any  Interest  Period (as
defined below)  designated by the Borrower in such notice,  direct that interest
accrue on the  unpaid  principal  balance of this Note (or any  portion  thereof
which is in an amount of not less than $100,000 or any greater integral multiple
thereof) outstanding from time to time during such Interest Period at a rate per
annum  equal  to the sum of the  Adjusted  LIBOR  (as  defined  below)  for such
Interest Period plus the Applicable  LIBOR Margin (as defined below);  provided,
further,  however,  that upon the occurrence and during the  continuation of any
Event of  Default  (as  defined  below),  the  Lender  may,  upon  notice to the
Borrower,  suspend  Borrower's right to use the aforesaid Adjusted LIBOR option.
Each such designation by the Borrower of an interest rate for this Note based on
the  Adjusted  LIBOR  and of an  Interest  Period  applicable  thereto  shall be
irrevocable  and shall remain in effect  throughout such Interest  Period.  Upon
determining any interest rate based on the Adjusted LIBOR for an Interest Period
requested  by the  Borrower,  the Lender shall  promptly  notify the Borrower by
telephone  (which shall be promptly  confirmed in writing by the Lender) of such
determination,  and such determination  shall, in the absence of manifest error,
be final, conclusive and binding for all purposes.  Notwithstanding  anything in
this Note to the contrary,  a prepayment of any portion of the principal balance
of this Note which is then bearing  interest  based on the Adjusted LIBOR may be
made without penalty by the Borrower only on the last day of the Interest Period
applicable  thereto and, if any such prepayment is made on a day that is not the
last day of the  applicable  Interest  Period,  the  Borrower  shall  pay to the
Lender,  upon the  Lender's  written  request to the  Borrower  therefor  (which
request  shall set forth the basis for the request of such payment in reasonable
detail and, in the absence of manifest  error,  shall be final,  conclusive  and
binding on the Lender and the Borrower),  an amount equal to any and all losses,
expenses and liabilities  (including,  without limitation,  any interest paid by
the Lender to the  extent not  recovered  by the Lender in  connection  with its
re-employment  of the  prepaid  funds  and  including  any  loss of  anticipated
profits)  which the  Lender  may  sustain  as a result of such  prepayment.  The
calculation  of any and all amounts  payable to the Lender  with  respect to any
portion of the  principal  balance of this Note  bearing  interest  based on the
Adjusted  LIBOR  shall be made as though  the Lender had  actually  funded  such
portion  through  the  purchase  of  deposits  in the London  interbank  market;
provided,  however,  that the Lender  may fund such  portion of this Note in any
manner  it  sees  fit and the  foregoing  assumptions  shall  be used  only  for
calculation of amounts which may be payable under this Note.

     As used in  this  Note,  the  following  terms  shall  have  the  following
meanings: (a) "Adjusted LIBOR" shall mean, for any Interest Period, the rate per
annum  (rounded  upwards  to the  nearest  1/16th  of one  percentage  point (if
necessary))  equal to the quotient obtained by dividing (x) the offered rate for
United States dollar  deposits for a period  comparable to such Interest  Period
appearing  on the  Telerate  Screen Page 3750 (or as quoted or published by such
other recognized independent quote service as may be selected by the Lender from
time to time)  as of  11:00  a.m.  (Atlanta  time)  on the date  that is two (2)
Business Days prior to the  beginning of such  Interest  Period (but if at least
two such rates appear on such screen or are so quoted at such time,  the offered
rate for such Interest Period shall be the arithmetic mean of such rates) by (y)
a  percentage  equal to one (1) minus the then  average  stated  maximum  amount
(stated as a decimal) of all reserve  requirements  applicable  to any member of
the Federal Reserve System in respect of Eurocurrency  liabilities as defined in
Regulation  D of the Board of Governors  of the Federal  Reserve  System (or any
successor  categories  for  such  liabilities  under  such  Regulation  D);  (b)
"Applicable LIBOR Margin" shall mean (i) one hundred  seventy-five  basis points
(1.75%)  during the period from the date of this Note  through  August 31, 2000,
(ii) two hundred basis points  (2.0%)  during the period from  September 1, 2000
through August 31, 2001, and (iii) two hundred  twenty-five basis points (2.25%)
during the period from and after  September 1, 2001;  (c)  "Business  Day" shall
mean any day  excluding  a  Saturday,  Sunday,  any other day on which banks are
required or permitted to be closed in the city in which  Lender's  address shown
in this Note is located, and any other day on which trading is not carried on by
and between banks in United States dollars in the London interbank  market;  (d)
"Interest  Period" shall mean, in the case of the  determination of any Adjusted
LIBOR,  a one, two,  three,  four, six or twelve month period as selected by the
Borrower  but (i) in the event any  Interest  Period would end on a day which is
not a  Business  Day,  such  Interest  Period  shall  be  deemed  to  end on the
immediately  succeeding  Business  Day unless  such  extension  would cause such
Interest  Period to end on the next  calendar  month in which case such Interest
Period shall be deemed to end on the  immediately  preceding  Business Day, (ii)
any  Interest  Period  which  begins on a day for which there is no  numerically
corresponding day in the calendar month in which such Interest Period ends shall
expire on the immediately  preceding  Business Day, and (iii) the Borrower shall
not be entitled to select any  Interest  Period which  extends  beyond the final
maturity  date of this  Note;  (e)  "LIBOR  Advance"  means any  portion  of the
principal  balance of this Note which bears interest based on Adjusted LIBOR for
a particular  Interest Period;  (f) "Prime Rate" shall mean the rate of interest
announced by Lender from time to time as its "prime rate," "prime lending rate,"
"base rate" or similar  reference  rate (any such rate  announced by Lender is a
reference rate only and does not  necessarily  represent the best or lowest rate
actually charged by it to any customer and the Lender may make loans at rates of
interest which are at, above or below such reference rate) and the Prime Rate in
effect at the close of business  on each  business  day of Lender  shall for the
purposes  of this  Note be the  Prime  Rate  for  that  day and any  immediately
succeeding  non-business day or days of Lender,  and in the event the Prime Rate
is  discontinued  as a standard,  the holder hereof shall designate a comparable
reference rate as a substitute therefor; and (g) "Prime Rate Advances" means any
and all portions of the principal balance of this Note which bear interest based
on the Prime Rate.

     This Note shall be payable as follows:

                  (a) Accrued interest on this Note shall be payable as follows:
         (i)  during the period  from the date of this Note  through  August 31,
         1998, accrued interest shall be payable quarterly in arrears on so much
         of the  principal  balance of this Note as then  consists of Prime Rate
         Advances,  which payments shall be due commencing on November 30, 1996,
         and shall continue to be on the last day of each February,  May, August

         interest  shall  be  payable  in  arrears  on so much of the  principal
         balance of this Note as then  consists of LIBOR  Advances at the end of
         each Interest Period applicable  thereto (and, in the case of any LIBOR
         Advance  having an Interest  Period in excess of three months,  accrued
         interest  thereon  shall be due on each day which  occurs  every  three
         months after the initial date of such Interest Period), and (ii) during
         the period from and after September 1, 1998,  accrued interest shall be
         payable in arrears on each date on which a payment of  principal is due
         on this Note pursuant to paragraph (b) below; and

                  (b) The  principal  balance of this Note shall be repayable in
         sixty (60) consecutive monthly  installments each in an amount equal to
         one-sixtieth (1/60th) of the outstanding principal balance of this Note
         as of the opening of the Lender's  business on September 1, 1998, which
         installments  shall be due  commencing  on October  1, 1998,  and shall
         continue to be due on the same day of each succeeding  month thereafter
         up to and through September 1, 2003, except that in all cases the final
         installment  of principal  due  hereunder on such final  maturity  date
         shall be in an amount equal to the entire  remaining  unpaid  principal
         balance of this Note.

     This Note is the "Note"  referred to in the Third Amended and Restated Loan
Agreement of even date between Borrower and Lender (said agreement,  as the same
may be hereafter  amended,  supplemented,  or restated,  being herein called the
"Loan  Agreement")  and this Note  evidences  any and all Loans now or hereafter
made by Lender to Borrower thereunder.

     Borrower  shall pay a late charge of five percent  (5%) of any  installment
payment  hereunder  which is not paid within ten (10) days after such payment is
due.  During the existence of any Event of Default  under this Note,  the unpaid
principal and accrued  interest balance of this Note shall bear interest on each
day  until  paid  at the  Prime  Rate  (as  defined  above)  plus,  in  Lender's
discretion,  up to an  additional  (i) two  percentage  points (2.0%) during the
period  from the  date of this  Note  through  August  31,  2001 or (ii) two and
one-quarter  percentage  points (2.25%) from and after September 1, 2001, but in
each such  period  only to the  extent  that  payment of such  interest  on such
principal  or interest is  enforceable  under  applicable  law.  All payments or
prepayments on this Note shall be applied,  first,  to interest  accrued on this
Note through the date of such payment or prepayment  and then to principal  (and
any  partial  principal  prepayments  on this Note made  prior to the date shown
above on which the  initial  principal  installment  is due  hereunder  shall be
applied to such installments in the inverse order of their maturity).

     Borrower may, upon thirty (30) days' prior written notice to Lender, prepay
the  principal  balance  of this  Note in whole or in part  without  premium  or
penalty but any  prepayment  of any portion of this Note then  bearing  interest
based on Adjusted  LIBOR will be subject to certain  additional  provisions  set
forth  above and any  partial  prepayment  of this Note shall be applied as also
provided above. In addition, in the event Borrower sells, transfers,  assigns or
otherwise  conveys any of its property to another person,  Borrower shall make a
mandatory principal prepayment on this Note, without premium or penalty,  within
five (5) business days after the closing of such  transaction,  which prepayment
shall be in an amount  equal to one hundred  percent  (100%) of the  proceeds of
such transaction (net of the cost of such transaction,  including any reasonable
sales  commissions  paid to persons who are not affiliated with the Borrower and
also net of any taxes  payable by the Borrower on account of such  transaction),
except that this  principal  prepayment  requirement  shall not apply to (i) any
sale by Borrower of its inventory in the ordinary  course of its business,  (ii)
any sale or other  disposition by Borrower of any of its obsolete or unnecessary
equipment  so long as the net  proceeds  of each  such  disposition  are used by
Borrower to replace such  equipment or purchase  other  equipment,  or (iii) any
other sale or  disposition  of any  property  by  Borrower  which the Lender has
expressly  agreed in writing  will be exempt from this  prepayment  requirement.
Notwithstanding the foregoing, however, no prepayment pursuant to this paragraph
shall be due in any  particular  fiscal  year of  Borrower  unless and until the
total amount of such net proceeds for all such sales or other  conveyances  made
during such fiscal year exceeds $500,000.

     Upon the  occurrence  of an Event of  Default  under  (and as such  term is
defined in) the Loan Agreement,  Lender, at its option, without demand or notice
of any kind,  may declare this Note  immediately  due and payable.  In case this
Note is collected by or through an attorney-at-law, all costs of such collection
incurred by the Lender,  including reasonable  attorney's fees, shall be paid by
Borrower (but not to exceed actual fees and expenses incurred).

     Time is of the essence of this Note. Demand, presentment, notice, notice of
demand, notice for payment,  protest and notice of dishonor are hereby waived by
each and every maker, guarantor,  surety and other person or entity primarily or
secondarily  liable on this Note. Lender shall not be deemed to waive any of its
rights under this Note unless such waiver be in writing and signed by Lender. No
delay or  omission  by Lender in  exercising  any of its rights  under this Note
shall operate as a waiver of such rights and a waiver in writing on one occasion
shall not be construed as a consent to or a waiver of any right or remedy on any
future occasion.

     This Note shall be governed by and  construed  and  enforced in  accordance
with the laws of the State of Georgia (without giving effect to its conflicts of
law rules).  Whenever possible, each provision of this Note shall be interpreted
in such manner as to be  effective  and valid under  applicable  law, but if any
provision of this Note shall be prohibited by or invalid under  applicable  law,
such provision  shall be ineffective  only to the extent of such  prohibition or
invalidity,  without  invalidating  the  remainder  of  such  provision  or  the
remaining provisions of this Note.

     Words  importing  the singular  number  hereunder  shall include the plural
number and vice versa,  and any pronoun used herein shall be deemed to cover all
genders. "Person" as used herein means any individual, corporation, partnership,
joint  venture,   association,   joint  stock  company,  trust,   unincorporated
association or government or any agency or political  subdivision  thereof.  The
word "Lender" as used herein shall include  transferees,  successors and assigns
of Lender,  and all rights of Lender hereunder shall inure to the benefit of its

year first above set forth.

                                    EXHIBIT B

                     AMENDED AND RESTATED SECURITY AGREEMENT


     THIS  AGREEMENT  is made and entered  into as of August 30,  1996,  between
NATIONSBANK, N.A. (SOUTH), a national banking association which is the successor
by merger to Bank South, a Georgia  banking  corporation  formerly known as Bank
South,  N.A.,  having its main office at 600 Peachtree  Street,  N.E.,  Atlanta,
Georgia  30308  ("Secured  Party"),  and CRYOLIFE,  INC., a Florida  corporation
having its chief executive  office and principal place of business at 2211 North
Market Parkway, Suite 142, Marietta, Cobb County, Georgia 30067 ("Debtor").

                               STATEMENT OF FACTS

     Secured Party holds certain liens on certain of Debtor's equipment pursuant
to an  Equipment  Security  Agreement,  dated as of August 4, 1994,  executed by
Debtor in favor of Secured Party (the "Prior Security  Agreement"),  which liens
secured  certain of the loans made by Secured  Party to Debtor  under the Second
Amended and Restated Loan  Agreement,  also dated as of August 4, 1994,  between
Secured Party and Debtor (the "Prior Loan Agreement").

     Secured  Party and Debtor  have  agreed to amend and restate the Prior Loan
Agreement by entering into a Third Amended and Restated Loan Agreement, dated as
of the date hereof, between Secured Party and the Debtor (said agreement, as the
same may be  amended,  supplemented  or  restated,  is herein  called the "Third
Restated  Loan  Agreement").  It is a  condition  precedent  to Secured  Party's
obligation to make loans to Debtor under the Third  Restated Loan Agreement that
the Prior  Security  Agreement  be amended  and  restated  as  provided  in this
Agreement, and that parties are entering into this Agreement for such purpose.

     In  consideration  of any and all loans or other extensions of credit which
may be now or hereafter  made from time to time by Secured Party to Debtor under
the  Third  Restated  Loan  Agreement,  as well as for other  good and  valuable
consideration, the receipt and adequacy of which are hereby acknowledged, Debtor
and  Secured  Party do hereby  agree to amend  and  restate  the Prior  Security
Agreement as follows:

                               STATEMENT OF FACTS

     (b) The term  "Collateral"  as used  herein  shall mean and include all now
existing or hereafter  arising rights,  titles and interests of Debtor in, to or
under the following  types or items of property of Debtor,  whether now owned or
hereafter  existing or hereafter  created,  acquired or arising and  wheresoever

                  trademarks, service marks, trade names, copyrights, good will,
                  customer  lists,  tax refund claims,  computer  programs,  and

                  security  interests  or other  security  held by or granted to
                  Debtor  to secure  payment  of any of its  accounts,  contract
                  rights, chattel paper, instruments or general intangibles, and
                  all  rights  to  indemnification   and  all  other  intangible

                  Debtor or for display or  demonstration,  all work in process,
                  all raw materials, all finished goods, and all other materials

                  and other general intangibles of Debtor relating to any of the
                  foregoing (collectively, the "Equipment").

         Notwithstanding  anything herein to the contrary,  the Collateral shall
not  include  any of Debtor's  Intellectual  Property  Rights (as defined in the
Third Restated Loan  Agreement)  but the  Collateral  shall include the proceeds
thereof.

         (c)  Unless  otherwise  defined  herein,  all terms  contained  in this
Agreement shall have the meanings provided for by the Uniform Commercial Code as
in effect in the State of  Georgia  to the  extent  the same are used or defined
therein.  In addition,  the term "proceeds" as used herein includes  whatever is
receivable  or received  when any  Collateral  or any proceeds  thereof is sold,

such Collateral. In addition, all references herein to a particular type or item
of Collateral shall be deemed to include all now existing or hereafter  acquired
books and records of Debtor  relating  to such  Collateral  (including,  without
limitation, all computer materials and records). The Collateral also includes in
all cases all monies and other property of Debtor of any other kind which may be

all deposit or other  accounts of Debtor with Secured  Party and all balances or
other property now or hereafter held or on deposit therein.

         2. OBLIGATIONS  SECURED.  This Agreement and the security  interest and
lien granted hereunder to Secured Party secures all obligations which may be now
or hereafter  owing by Debtor to Secured  Party under this  Agreement as well as
any and all  indebtedness,  obligations or other liabilities which may be now or
hereafter  owing by the Debtor to Secured Party under or on account of the Third
Restated  Loan  Agreement  or any of the other  Financing  Documents  as defined
therein, and including without limitation any interest which, but for the filing

together with such additional  writings,  including,  without  limitation,  duly

         4.  COVENANTS  AND  AGREEMENTS OF DEBTOR.  Debtor hereby  covenants and

Collateral.

         (g)  Debtor  agrees  that  such  care as  Secured  Party  gives  to the

account fully for and promptly  deliver to Secured Party,  in the form received,

security interest in the Collateral,  including,  without limitation,  obtaining
such landlord waivers, mortgagee waivers and other assurances from third parties
regarding  Secured  Party's  access  to and  right to  foreclose  on or sell the

hereby authorizes  Secured Party to execute and file any financing  statement or
fixture  filing on  Debtor's  behalf,  and the  parties  further  agree that any
carbon,  photographic,   or  other  reproduction  of  this  Agreement  shall  be
sufficient as a financing  statement and may be filed in any appropriate  office
in lieu thereof.

         (k) Debtor shall reimburse  Secured Party upon demand for all costs and
expenses,  including, without limitation,  actual and reasonable attorney's fees
and disbursements,  Secured Party may now or hereafter incur while exercising or

Agreement or by law, all of which costs and expenses  shall  constitute  part of
the Obligations secured hereunder.

         (l) Debtor  shall give  Secured  Party not less than  thirty  (30) days
prior  written  notice  of any  change in  Debtor's  chief  executive  office or

         (m) Debtor shall keep its records concerning the Collateral at Debtor's
address set forth above or at Debtor's other  location(s)  (if any) set forth on
Schedule 1 attached to this  Agreement  and shall not remove such  records  from

         (n) Debtor shall keep all  Collateral  consisting  of goods (other than

or at Debtor's other locations (if any) set forth on Schedule 1 attached to this
Agreement,  and Debtor shall not,  without the prior written approval of Secured
Party,  remove any  Collateral  therefrom  except for sales of  Inventory in the
ordinary  course  of  business  and the  disposition  of  obsolete  or  worn-out
Equipment in accordance  with this Agreement and except for the storage of goods
at  locations  other than those shown above or on Schedule 1 attached  hereto if
(i) Debtor gives  Secured Party  written  notice of the new storage  location at
least thirty (30) days prior to storing such  Collateral at such location,  (ii)
Secured Party's security interest in such Collateral  hereunder is and continues
to be duly  perfected,  (iii) all documents and other receipts in respect of any

of such  Collateral  and to permit Secured Party to have the right to enter upon
and use such premises in order to inspect,  store,  process,  assemble or remove
the Collateral therefrom after the occurrence of an Event of Default.

         (o) Debtor shall furnish Secured Party with such information  regarding
the Collateral (and any account  debtors  thereunder) as Secured Party from time
to time may request.

         (p) Debtor shall keep the  Collateral in good  condition and repair and
shall not cause or permit any waste of any of the Collateral.

         (q) Debtor shall  insure the  Collateral,  with Secured  Party named as
loss payee under all property  coverages and as an additional  insured under all
liability  coverages,  in form and amount, with insurers,  and against risks and
liabilities which are satisfactory to Secured Party in all respects,  and Debtor
hereby assigns all such policies and all proceeds  thereof  (including  returned
premiums) to Secured Party, to secure the Obligations, agrees to deliver them to
Secured  Party at its request,  and agrees that Secured Party may make any claim
thereunder,  cancel the  insurance  on default by Debtor,  collect  and  receive
payment and indorse any instrument in payment of loss or return premium or other
refund or return, and apply such amounts received,  at Secured Party's election,
to replacement of the Collateral or to the Obligations.  Debtor shall not use or
permit  the  use of any of the  Collateral  in  any  manner  which  will  render
inapplicable or invalid any insurance  coverage  therefor.  Debtor shall deliver
the  originals of all property  insurance  policies  covering the  Collateral to
Secured  Party  together  with loss  payable  endorsements  thereon  in form and
substance satisfactory to Secured Party and in the name of Secured Party as loss
payee  thereunder.  Each  policy of  insurance  or each such  endorsement  shall
contain a clause  requiring  the  insurer to give not less than thirty (30) days
prior written notice to Secured Party in the event of cancellation of the policy
for  nonpayment  of premium  and a clause to the effect  that the  interests  of
Secured  Party  thereunder  shall not be impaired or  invalidated  by any act or
neglect of Debtor nor by the  occupation  of the  premises  covered  thereby for
purposes more hazardous than are permitted by said policy.

         (r) Debtor agrees that all risk of loss of the Collateral  shall at all
times be and remain upon Debtor  irrespective of whether such Collateral is then
in Debtor's or Secured Party's possession.

         (s) Debtor  agrees that any of the  Collateral  consisting of Equipment
shall be and remain personal property and shall not, by reason of its attachment
or other  connection  to any real  property,  either become or be deemed to be a
fixture or  appurtenance  to such real property and shall at all times be deemed
severable therefrom.

         (t) Debtor  shall permit  Secured  Party (or any person  designated  by
Secured Party) from time to time to inspect the Collateral and to inspect, audit
and make copies of or extracts  from all books and records  maintained  by or on
behalf of Debtor pertaining to the Collateral (including computer records),  all
at such times and places as Secured Party may request from time to time.

         5. POWER OF  ATTORNEY.  Debtor  hereby  agrees  that from time to time,
without presentment, notice or demand, and without affecting or impairing in any
way the rights of Secured Party with respect to the Collateral,  the obligations
of Debtor hereunder or the other  Obligations,  Secured Party may, but shall not
be  obligated  to and shall incur no  liability to Debtor or any third party for
failing to, take any action which Debtor is obligated by this  Agreement to take
but which the Debtor  fails to take,  and Debtor  also  hereby  appoints  (which
appointment is coupled with an interest and shall be irrevocable so long as this
Agreement is in effect)  Secured Party as its  attorney-in-fact  with full power
and  authority  at any  time to take any of the  following  actions  during  the
existence  of any Event of  Default  hereunder  in either  Debtor's  or  Secured
Party's name (but Secured  Party shall have no  obligation to and shall incur no
liability to Debtor or any third party for failing to exercise any such power or
authority):  (a) to collect  by legal  proceedings  or  otherwise  and  indorse,
receive and receipt for all dividends,  interest,  payments, proceeds, and other

Collateral;  (g) to receive, open and dispose of Debtor's mail pertaining to any
of  the  Collateral   consisting  of  Accounts  Receivables  and  notify  postal
authorities to deliver such mail to such address as Secured Party may designate;
(h) to indorse Debtor's name upon any checks or other proceeds of any Collateral
and deposit same to any account of Secured Party;  (i) to indorse  Debtor's name

name or Debtor's name, and without prior notice to or demand upon Debtor. Debtor
agrees to reimburse  Secured  Party on demand for any sums  advanced or expenses
incurred by Secured Party in exercising  any of the foregoing  rights and powers
together  with  interest  accruing  thereon daily at the highest rate Debtor has
contracted to pay on any of the Obligations.  Debtor's reimbursement obligations
under this Section shall constitute part of the Obligations secured hereunder.

         6. EVENTS OF DEFAULT. An event of default under this Agreement shall be
deemed to exist upon the  occurrence  of any of the  following  event (each such
event being herein called an "Event of Default"):

         (a) If any representation, or warranty of Debtor made in this Agreement
proves to have been untrue, incorrect,  misleading or incomplete in any material
respect as of the date made or deemed made;

         (b) Failure of Debtor to perform, observe, discharge or comply with any
of the covenants set forth in Section 4 (other than  subsection  (e), (k) or (l)
thereof) of this  Agreement,  which failure is not cured within thirty (30) days
of the giving by Secured Party to Debtor of written notice of same;

         (c)  Failure  of  Debtor  punctually  and  fully to  perform,  observe,
discharge or comply with any of the other covenants set forth in this Agreement;

         (d) The  occurrence  of any other  Event of Default  under (and as such
term is defined in) the Third Restated Loan Agreement.

         7.  SECURED  PARTY'S  REMEDIES.  Upon the  occurrence  and  during  the
continuation  of any one or more of the  foregoing  Events of  Default,  Secured
Party  may,  at its  option,  and  without  notice to or demand on Debtor and in
addition to all rights and remedies  available to Secured  Party under the Third
Restated Loan Agreement or any of the other Financing  Documents,  or at law, in
equity, or otherwise, do any one or more of the following:

         (a)  Secured  Party may  declare  any or all of the  Obligations  to be
immediately  due and payable and foreclose or otherwise  enforce Secured Party's
security  interest in or other lien hereunder on any or all of the Collateral in
any manner permitted by law or provided for in this Agreement.

         (b)  Secured  Party may  recover  from  Debtor all costs and  expenses,
including,  without limitation,  actual and reasonable attorney's fees, incurred
or paid by Secured Party in exercising or enforcing any right,  power, or remedy
with respect to any or all of the Collateral provided to it by this Agreement or
by applicable law. Notwithstanding anything herein to the contrary, the Debtor's
liability under this Agreement for the Secured Party's attorney's fees shall not
exceed the attorney's fees actually incurred by the Secured Party.

         (c)  Secured  Party may require  Debtor to  assemble  any or all of the
Collateral and make it available to Secured Party at such place or places as may
be designated by Secured Party.

         (d) Secured Party may enter onto any property  where any  Collateral is
located and take possession thereof with or without judicial process.

         (e) Prior to Lender's disposition of any Collateral,  Secured Party may
store, process,  complete,  repair or recondition it or otherwise prepare it for
disposition in any manner and to the extent Secured Party deems appropriate (but
Secured Party shall not be obligated to do so).

         (f) Secured  Party may  transfer any of the  Collateral  into its name,
notify any account  debtor under or other person  obligated on any Collateral to
make payments  thereunder  directly to Secured Party,  and otherwise  collect or
enforce  payment  of any of the  Collateral  (but  Secured  Party  shall have no
obligation to do any of the foregoing).

         (g)  Secured  Party  may  sell  or  otherwise  dispose  of  any  of the
Collateral at one or more public or private sales at Debtor's or Secured Party's
place of business or any other place or places,  including without limitation at
any  brokers  board or  security  exchange,  in lots or in bulk,  for cash or on
credit,  all as Secured Party,  in its discretion,  may deem  advisable.  Debtor
agrees that seven (7) days' prior written notice from Secured Party to Debtor of
any public sale of any  Collateral  or the date after which any private  sale of
any Collateral will be held shall constitute  reasonable notice thereof and such
sale may be held at such  locations as Secured  Party may designate in each said
notice.  Secured Party shall have the right to conduct any such sale on Debtor's
premises,  without any charge therefor, and any such sales may be adjourned from
time to time in accordance with  applicable law.  Secured Party may purchase all
or any part of the  Collateral  at any public sale or, if  permitted by law, any
private  sale and, in lieu of actual  payment of such  purchase  price,  Secured
Party may set-off the amount of such price against the Obligations.

         (h) Secured Party is hereby  granted by Debtor a license or other right
to use during the term of this Agreement, without charge, any or all of Debtor's
labels, patents,  software,  copyrights,  trade secrets, trade names, trademarks
and advertising  materials,  or any other property of any similar nature,  as it
pertains  to any of the  Collateral,  in  advertising  for sale and  selling any
Collateral or in completing  Debtor's  performance  under or collecting any sums
owing in respect of any  Collateral,  and Debtor's rights under all licenses and
all  franchise  agreements  relating  to any of the  Collateral  shall  inure to
Secured  Party's  benefit to the extent of Secured  Party's  rights,  titles and
interests in or to the Collateral under this Agreement.

         (i) Secured Party also may, without prior notice or demand of any kind,
hold and set-off against such of the Obligations  (whether matured or unmatured)
as Secured  Party may elect any balance of amount to the credit of Debtor in any
deposit,  agency,  reserve,  holdback or other account of any nature  whatsoever
which may be now or hereafter  maintained by or on behalf of Debtor with Secured
Party in any of its offices,  regardless  of whether any such account is general
or special and regardless of whether any such account is individual or joint.

         8. APPLICATION OF PROCEEDS.  (a) All monies and other proceeds received
by  Secured  Party  upon  any  collection,  sale  or  other  disposition  of any
Collateral,  together  with all other  monies  and other  proceeds  received  by
Secured Party hereunder, shall be applied as follows:

                           First,  to the  payment of the  reasonable  costs and
                  expenses of such sale,  collection or other  disposition which
                  may have been  incurred by Secured  Party,  including  without
                  limitation  actual and reasonable  attorney's fees as provided
                  in  Section  7(b)  above  and all other  reasonable  expenses,
                  liabilities  and advances made or incurred by Secured Party in
                  connection therewith;

                           Second,  to the payment of all other Obligations then
                  due in such order as Secured Party may elect; and

                           Third,  after payment in full of all Obligations then
                  due, any surplus then  remaining  from such proceeds  shall be
                  paid to Debtor; and

         (b) Debtor  shall  remain  liable to Secured  Party for any  deficiency
owing on the Obligations after the application of the proceeds of the Collateral
as provided above.

         9. INDEMNITY.  Debtor hereby agrees to indemnity Secured Party and hold
Secured Party  harmless  from and against any claim,  liability,  loss,  damage,
expense,  suit,  action or proceeding  which may now or hereafter be suffered or
incurred by Secured Party as a result of Debtor's failure to observe, perform or
discharge Debtor's duties or obligations hereunder or Secured Party's holding or
administering this Agreement or any Collateral unless with respect to any of the
above Secured Party is finally determined to have acted with gross negligence or
to have engaged in willful  misconduct.  Without  limiting the generality of the
foregoing,  this indemnity shall extend to any claims  asserted  against Secured
Party by any person under any environmental,  occupational safety and hazard, or
other  similar  laws,  rules or  regulations  by reason of Debtor's or any other
person's  failure  to  comply  with any such  laws,  rules or  regulations.  The
indemnity  obligations  of Debtor under this Section shall  constitute a part of
the  Obligations  secured  hereunder and shall survive the  termination  of this
Agreement.

         10. MISCELLANEOUS.  (a) Any waiver,  forbearance or failure or delay by
Secured Party in exercising  any of its rights,  powers,  or remedies  hereunder
shall not preclude the further  exercise  thereof,  and every right,  power,  or
remedy of Secured Party  hereunder shall continue in full force and effect until
such  right,  power or remedy is  specifically  waived in a writing  executed by
Secured  Party.  Debtor  waives  any right to require  Secured  Party to proceed
against  any  person or to  exhaust  any  Collateral  or to pursue any remedy in
Secured Party's power.

         (b)  This   Agreement   may  be  executed  in  any  number  of  several
counterparts,  each of which when so executed  shall be deemed to be an original
and all of which  counterparts  taken together shall constitute one and the same
instrument.

         (c) This Agreement  contains the entire agreement between Secured Party
and Debtor with respect to the  Collateral and supersedes and replaces the Prior
Security  Agreement as well as any and all other prior agreements,  commitments,
understandings,   negotiations  or  correspondence  between  them  with  respect
thereto.  If any provision of this Agreement shall be held invalid or prohibited
under applicable law, this Agreement shall be invalid or ineffective only to the
extent of such invalidity or prohibition,  without invalidating the remainder of
this Agreement.

         (d) The  rights,  powers,  and  remedies  of Secured  Party  under this
Agreement shall be in addition to all other rights, powers, or remedies given to
Secured Party by applicable law or by any other agreement,  all of which rights,
powers and remedies  shall be  cumulative  and may be exercise  successively  or
concurrently  without  impairing  Secured Party's security  interest in or other
lien on any of the Collateral.

         (e) All singular  terms used herein  shall  include the plural and vice
versa.  All  pronouns  used  herein  shall be deemed to cover all  genders.  All
headings  used  herein  are for  convenience  of  reference  only and  shall not
constitute a substantive part of this Agreement.

         (f) This  Agreement may not be amended or modified  except by a writing
signed by each of the parties hereto.

         (g) Except as may be otherwise  expressly provided herein, all notices,
requests and demands to or upon any party  hereto  shall be given in  accordance
with the notice provisions of the Third Restated Loan Agreement.

         (h) All rights of Secured Party under this Agreement shall inure to the
benefit of its successors and assigns,  and all obligations of Debtor  hereunder
shall bind its successors, and assigns.

         (i) This  Agreement and all security  interests and other liens granted
or  conveyed  hereunder  shall  remain  in full  force and  effect  and shall be
irrevocable  until such time as (x) no Obligations  are  outstanding and (y) the
Third Restated Loan  Agreement is no longer in effect.  Debtor hereby waives any
right Debtor may have upon payment in full of the Obligations to require Secured
Party to terminate  its security  interest in the  Collateral  or any  financing
statement relating thereto until this Agreement is terminated in accordance with
the foregoing terms.

         (j) This Agreement  shall be construed in accordance  with and governed
by the laws of the State of Georgia  without  giving effect to its choice of law
rules.

         (k) Time is of the essence of this Agreement.

         IN  WITNESS  WHEREOF,  Debtor  and  Secured  Party  have  executed  and
delivered this Agreement,  and Debtor has affixed its seal hereto, as of the day
and year first above set forth.

         WHEREAS, the Pledgor and the Pledgee are parties to a Third Amended and

all of the shares of capital stock of the Subsidiary set forth on Schedule 1 and
all  other  shares of such  stock  which  may be now or  hereafter  owned by the

         3. PLEDGE OF SECURITIES, ETC.

            3.1 PLEDGE.  To secure the Secured  Obligations and for the purposes
set forth in Section 1, the  Pledgor  hereby  pledges to the Pledgee the Pledged
Stock,  together  with (i) the  certificates  representing  such  Pledged  Stock
accompanied by stock powers duly executed in blank by the Pledgor,  and (ii) all
dividends  (whether in cash, stock,  warrants,  options,  or other  securities),

            3.2  DEFINITION OF PLEDGED  SECURITIES AND  COLLATERAL.  The Pledged
Stock and all items  described  in clause  (ii) of Section  3.1 are  hereinafter

blank or in favor of the Pledgee or any nominee or nominees of the Pledgee or an
agent appointed by the Pledgee.

         5. VOTING, ETC. Unless and until an Event of Default (such term to mean

or in substitution  for the Pledged  Securities  except to the Pledgor,  and any

         paragraph (c) above,  which failure shall continue for thirty (30) days
         after the Pledgee gives the Pledgor notice of same.

         7.2  REMEDIES.  In case an Event of Default  shall have occurred and be
continuing,  the Pledgee shall be entitled to exercise all of the rights, powers
and  remedies  (whether  vested in it by this  Agreement,  any  other  Financing
Document or by law and including, without limitation, all rights and remedies of
a secured  party of a debtor in default under the Uniform  Commercial  Code (the
"Code") in effect in the State of Georgia at that time) for the  protection  and
enforcement of its rights in respect of the Collateral, and the Pledgee shall be
entitled,  without  limitation,  to exercise  the  following  rights,  which the
Pledgor hereby agrees to be commercially reasonable:

            (i) to receive  all  amounts  payable  in respect of the  Collateral
         otherwise  payable  under  Section 6 to the  Pledgor and to enforce the
         payment of the Pledged  Securities  and to exercise  all of the rights,
         powers, and remedies of the Pledgor thereunder;

            (ii)  to  transfer  all  or any  part  of the  Collateral  into  the
         Pledgee's name or the name of its nominee or nominees;

            (iii)  to vote  all or any part of the  Collateral  (whether  or not
         transferred  into the  name of the  Pledgee)  and  give  all  consents,
         waivers and  ratifications  in respect of the  Collateral and otherwise
         act with respect thereto as though it were the outright owner thereof;

            (iv) at any time or from time to time to sell,  assign and  deliver,
         or grant options to purchase,  all or any part of the Collateral in one
         or more parcels, or any interest therein, at any public or private sale
         at any exchange,  broker's board or at any of the Pledgee's  offices or
         elsewhere,  without demand of performance,  advertisement  or notice of
         intention  to  sell  or of the  time or  place  of sale or  adjournment
         thereof or to redeem or  otherwise  (all of which are hereby  expressly
         and  irrevocably  waived by the  Pledgor),  for cash,  on credit or for
         other property, for immediate or future delivery without any assumption
         of credit  risk,  and for such price or prices and on such terms as the
         Pledgee in its sole  discretion may determine;  the Pledgor agrees that
         to the  extent  that  notice of sale shall be  required  by law that at
         least ten (10) days  notice to the Pledgor of the time and place of any
         public  sale or the time  after  which any  private  sale is to be made
         shall  constitute  reasonable  notification;  the Pledgee  shall not be
         obligated to make any sale of  Collateral  regardless of notice of sale
         having been given;  the Pledgee may adjourn any public or private  sale
         from time to time by announcement at the time and place fixed therefor,
         and any such sale may, without further notice,  be made at the time and
         place to which it was so  adjourned;  the  Pledgor  hereby  waives  and
         releases to the fullest extent  permitted by law any right or equity of
         redemption with respect to the Collateral, whether before or after sale
         hereunder,  and all rights,  if any, of marshalling  the Collateral and
         any other  security for the Secured  Obligations  or otherwise;  at any
         such sale, unless prohibited by applicable law, the Pledgee may bid for
         and  purchase all or any part of the  Collateral  so sold free from any
         such right or equity of redemption; and the Pledgee shall not be liable
         for failure to collect or realize upon any or all of the  Collateral or
         for any delay in so doing nor shall any of them be under any obligation
         to take any action whatsoever with regard thereto;

            (v)  to  settle,  adjust,   compromise  and  arrange  all  accounts,
         controversies,  questions, claims and demands whatsoever in relation to
         all or any part of the Collateral;

            (vi) to execute all such contracts, agreements, deeds, documents and
         instruments;  to bring, defend and abandon all such actions,  suits and
         proceedings;  and to take all actions in relation to all or any part of
         the Collateral as the Pledgee in its sole discretion may determine;

            (vii) to appoint managers,  agents, officers and servants for any of
         the purposes  mentioned in the  foregoing  provisions of this Section 7
         and to dismiss the same, all as the Pledgee in its sole  discretion may
         determine; and

            (viii)  generally,  to take all such other  action as the Pledgee in
         its sole  discretion may determine as incidental or conducive to any of
         the matters or powers  mentioned in the  foregoing  provisions  of this
         Section 7 and which the Pledgee  may or can do lawfully  and to use the
         name of the Pledgor for the purposes  aforesaid and in any  proceedings
         arising therefrom.

         8.  REMEDIES,  ETC.,  CUMULATIVE.  Each right,  power and remedy of the
Pledgee provided for in this Agreement or any other Financing Document or now or
hereafter  existing at law or in equity or by statute  shall be  cumulative  and
concurrent and shall be in addition to every other such right,  power or remedy.
The  exercise or  beginning of the exercise by the Pledgee of any one or more of
the  rights,  powers or remedies  provided  for in this  Agreement  or any other
Financing  Document  or now or  hereafter  existing  at law or in  equity  or by
statute or otherwise  shall not preclude the  simultaneous  or later exercise by
the  Pledgee of all such other  rights,  powers or  remedies,  and no failure or
delay on the part of the  Pledgee to exercise  any such  right,  power or remedy
shall operate as a waiver thereof.

         9.  APPLICATION OF PROCEEDS.  All moneys  collected by the Pledgee upon
any sale or other disposition of the Collateral,  together with all other moneys
received by the Pledgee hereunder, shall be applied as follows:

                  First,  to the payment of the costs and expenses of such sale,
         collection  or  other  realization,   including,   without  limitation,
         reasonable  attorneys'  fees actually  incurred and all other expenses,
         liabilities  and  advances  actually  made or actually  incurred by the
         Pledgee in connection therewith;

                  Second,  to the payment of the Secured  Obligations  then due;
         and

                  Third,  after payment in full of all Secured  Obligations then
         due, to the Pledgor, or its successors or assigns, or to whomsoever may
         be lawfully  entitled  to receive  the same or as a court of  competent
         jurisdiction may direct any surplus then remaining from such proceeds.

         10.  PURCHASERS OF  COLLATERAL.  Upon any sale of any of the Collateral
hereunder  (whether by virtue of the power of sale herein  granted,  pursuant to
judicial process or otherwise), the receipt of the Pledgee or the officer making
the sale shall be a sufficient  discharge to the  purchaser or purchasers of the
Collateral so sold, and such  purchaser or purchasers  shall not be obligated to
see to the  application  of any  part of the  purchase  money  paid  over to the
Pledgee or such officer or be  answerable in any way for the  misapplication  or
nonapplication thereof.

         11. PAYMENT OF EXPENSES;  INDEMNITY.  The Pledgor shall: (i) whether or
not the transactions  hereby  contemplated  are consummated,  pay all reasonable
out-of-pocket  costs and expenses of the Pledgee actually incurred in connection
with the  administration  (both  before  and  after  the  execution  hereof  and
including  advice of counsel as to the  rights  and duties of the  Pledgee  with
respect  thereto) of the Pledgee incurred in connection with the preservation of
rights  under,  and  enforcement  of,  and,  after  an  Event  of  Default,  the
renegotiation or  restructuring  of this Agreement and any amendment,  waiver or
consent relating thereto (including, without limitation, the reasonable fees and
disbursements  of  counsel  for the  Pledgee,  not to  exceed  actual  fees  and
disbursements);  (ii) pay and hold the Pledgee harmless from and against any and
all  present  and  future  stamp or  documentary  taxes or any  other  excise or
property  taxes,  charges or similar  levies  which arise from any payment  made
hereunder or from the execution,  delivery or registration of, or otherwise with
respect to this Agreement and save the Pledgee harmless from and against any and
all  liabilities  with respect to or resulting from any delay or omission to pay
any such  taxes,  charges  or  levies;  and (iii)  indemnify  the  Pledgee,  its
officers, directors, employees, representatives and agents from and hold each of
them harmless against any and all costs, losses, liabilities, claims, damages or
expenses  actually  incurred  by any of  them  (whether  or not  any of  them is
designated a party  thereto)  arising out of or by reason of any  investigation,
litigation  or other  proceeding  related to this  Agreement or any  transaction
contemplated  hereby,  including,  without  limitation,  the reasonable fees and
disbursements of counsel, not to exceed actual fees and disbursements,  incurred
in  connection  with any such  investigation,  litigation  or other  proceeding.
Notwithstanding  anything in this  Agreement to the contrary,  the Pledgor shall
not  be  responsible  to  the  Pledgee  or  any  officer,  director,   employee,
representative  or agent  of the  foregoing  (an  "Indemnified  Party")  for any
losses,  damages,  liabilities  or expenses  which result from such  Indemnified
Party's gross  negligence or willful  misconduct.  If and to the extent that the
obligations  of the  Pledgor  under this  Section 11 are  unenforceable  for any
reason,  the  Pledgor  hereby  agrees to make the  maximum  contribution  to the
payment  and  satisfaction  of  such  obligations  which  is  permissible  under
applicable  law. The Pledgor's  obligations  under this Section 11 shall survive
any termination of this Agreement.

         12. FURTHER  ASSURANCES.  The Pledgor agrees that it will join with the
Pledgee in  executing  and, at its own  expense,  file and refile under the Code
such financing statements,  continuation  statements and other documents in such
offices as the Pledgee may deem necessary or appropriate  and wherever  required
or  permitted by law in order to perfect and  preserve  the  Pledgee's  security
interest in the Collateral  and hereby  authorizes the Pledgee to file financing
statements and amendments  thereto relative to all or any part of the Collateral
without the  signature of the Pledgor  where  permitted by law, and agrees to do
such further acts and things and to promptly  execute and deliver to the Pledgee
such  additional  conveyances,  assignments,  agreements and  instruments as the
Pledgee  may  reasonably  require or deem  advisable  to carry  into  effect the
purposes of this Agreement or to further assure and confirm unto the Pledgee its
rights, powers and remedies hereunder.

         (b) The Pledgee shall be deemed to have  exercised  reasonable  care in
the  custody  and  preservation  of  the  Collateral  in its  possession  if the
Collateral is accorded treatment  substantially  equal to that which the Pledgee
accords its own property,  it being  understood  that the Pledgee shall not have
responsibility  for (i)  ascertaining  or taking  action with  respect to calls,
conversions,  exchanges,  maturities,  tenders or other matters  relative to any
Collateral,  whether or not the  Pledgee has or is deemed to have  knowledge  of
such matters,  or (ii) taking any necessary steps to preserve rights against any
parties with respect to any Collateral.

         14.  REPRESENTATIONS AND WARRANTIES.  The Pledgor hereby represents and
warrants that (i) it is the legal record and  beneficial  owner of, and has good

performance of this Agreement or consummation of the  transactions  contemplated
hereby, including, without limitation, the exercise by the Pledgee of the voting
or other rights provided for in this Agreement or the remedies in respect of the

and sale of securities  generally (or except as may already have been obtained);
(iv) all shares of Pledged  Stock have been duly and validly  issued,  are fully
paid and nonassessable;  and (v) the security interest in the Pledged Securities

pursuant to this  Agreement is not subject to any prior lien or  encumbrance  or
any agreement  purporting to grant to any third party a lien or  encumbrance  on
the  property  or  assets  of  the  Pledgor  which  would  include  the  Pledged
Securities.

demands of all persons whomsoever;  (ii) the Pledgor will have like title to and
right to pledge any other property at any time hereafter  pledged to the Pledgee

interest therein of the Pledgee; and (iii) the Pledgor will not, with respect to
any Collateral, enter into any shareholder agreements, voting agreements, voting

circumstance or occurrence whatsoever,  including,  without limitation:  (a) any
change in the time,  place or manner of payment of, or in any other term of, all

or receiver, or by any court, in any such proceeding, whether or not the Pledgor
shall have notice or knowledge  of any of the  foregoing;  or (f) any  exchange,
release or nonperfection of any other collateral,  or any release,  or amendment
or waiver of or consent to departure  from any guaranty or security,  for all or

         18. POWER OF ATTORNEY.  The Pledgor hereby  absolutely and  irrevocably
constitutes  and  appoints the Pledgee the  Pledgor's  true and lawful agent and
attorney-in-fact,  with full power of substitution,  in the name of the Pledgor:
(a) to execute  and do all such  assurances,  acts and things  which the Pledgor
ought to do but has failed to do under the covenants and provisions contained in
this  Agreement;  (b) to take any and all such action as the Pledgee may, in its
sole  discretion,  determine  as  necessary  or  advisable  for the  purpose  of
maintaining, preserving or protecting the security constituted by this Agreement
or any of the rights,  remedies,  powers or privileges of the Pledgee under this
Agreement;  and (c) generally, in the name of the Pledgor exercise all or any of
the powers, authorities, and discretions conferred on or reserved to the Pledgee

document of conveyance,  agreement,  or act as the Pledgee may deem proper in or
for the purpose of exercising any of such powers,  authorities  or  discretions.
The  Pledgor  hereby  ratifies  and  confirms,  and hereby  agrees to ratify and
confirm,  whatever  lawful  acts the  Pledgee  shall do or  purport to do in the
exercise  of the power of  attorney  granted  to the  Pledgee  pursuant  to this
Section 18, which power of attorney, being given for security, is irrevocable.

         19.  TERMINATION,  RELEASE.  Upon the termination of the Loan Agreement
and the full payment and  performance  of all of the Secured  Obligations,  this
Agreement shall  terminate,  and the Pledgee,  at the request and expense of the
Pledgor,  will  execute  and  deliver  to the  Pledgor  a proper  instrument  or
instruments  acknowledging  the  satisfaction and termination of this Agreement,
and will duly assign,  transfer and deliver to the Pledgor (without recourse and
without any  representation or warranty) such of the Collateral as may be in the
possession  of the Pledgee  and as has not  theretofore  been sold or  otherwise
applied or released pursuant to this Agreement,  together with any moneys at the
time held by the Pledgee hereunder.

         20. MISCELLANEOUS. The Pledgor agrees with the Pledgee that each of the
obligations  and  liabilities of the Pledgor to the Pledgee under this Agreement
may be  enforced  against  the  Pledgor  without  the  necessity  of joining the
Subsidiary,  any other holders of pledges of or security interests in any of the
Collateral,  or any  other  person as a party.  This  Agreement  shall  create a
continuing  security  interest in the  Collateral  and shall be binding upon the
Pledgor and its  successors and assigns and shall inure to the benefit of and be
enforceable by the Pledgee,  and its successors and assigns.  This Agreement may
be  changed,  waived,  discharged  or  terminated  only in  accordance  with the
provisions of the Loan Agreement. Unless otherwise defined herein or in the Loan
Agreement,  terms  defined in Article 9 of the Code in the State of Georgia  are
used herein as therein defined.  The headings in this Agreement are for purposes
of  reference  only and  shall  not limit or define  the  meaning  hereof.  This
Agreement may be executed in any number of counterparts,  each of which shall be
an original, but all of which shall constitute one instrument. In the event that
any provision of this Agreement shall prove to be invalid or unenforceable, such
provision  shall be deemed to be  severable  from the other  provisions  of this
Agreement which shall remain binding on all parties hereto.

         21. GOVERNING LAW. This Agreement and the rights and obligations of the
parties  hereunder  shall be construed in accordance with and be governed by the
internal laws of the State of Georgia.

         IN WITNESS  WHEREOF,  the  Pledgor  and the  Pledgee  have  caused this
Agreement  to be executed by their duly elected  officers  duly  authorized  and
Pledgor has caused its corporate seal to be hereunto affixed, all as of the date
first above written.

hereunder shall be made free and clear of and without deduction for any set-off,
counterclaim,  or withholdings  so that, in each case,  Lender shall receive the
full amount that it would  otherwise  be entitled to receive with respect to the
Obligations.  Guarantor  acknowledges  and agrees that this  Guaranty  Agreement
(this  "Guaranty")  is a guaranty of payment and not of collection  and that the
liability of Guarantor  under this  Guaranty  shall be immediate and primary and
shall  not be  contingent  upon the  exercise  or  enforcement  by Lender of any
remedies Lender may have against Borrower or any other person or the enforcement
of any lien or realization  upon any  collateral  Lender may at any time possess
for any of the Obligations.

         2.       OBLIGATIONS AND CREDIT DOCUMENTS DEFINED.

         (a) The  term  "Obligations"  as used  herein  shall  mean  any and all
indebtedness,  liabilities or obligations of Borrower to Lender which may now or
hereafter arise from or in any way relate to the Third Amended and Restated Loan
Agreement, dated as of August 30, 1996, between Borrower and Lender, or the Note
referred  to  therein,  or any other  agreement,  instrument  or other  document
executed  by  Borrower  with  or in  favor  of  Lender  under  or in  connection
therewith,   or  any   extensions,   renewals,   refinancings,   restructurings,
modifications  or  replacements,  in  whole  or in  part,  of or for  any of the
foregoing.

         (b) The term  "Obligations"  as used  herein also  expressly  includes,
without   limitation,   any  interest  which  would  accrue  on  the  applicable
Obligations  described  above but for the  filing by or  against  Borrower  of a
proceeding under any bankruptcy, insolvency, receivership or moratorium law.

         (c) The term "Credit  Documents"  as used herein shall mean and include
any and all  present or future  loan  agreements,  letter of credit  agreements,
lease   agreements,   security   agreements,   pledge   agreements,   collateral
assignments,  security deeds, mortgages, other security instruments,  promissory
notes, guaranties,  subordination agreements,  and any and all other agreements,
instruments  or  documents  which may now exist or may  hereafter be executed by
Borrower as evidence of or as collateral  for any or all of the  Obligations  or
pursuant to which any or all of the Obligations may be now or hereafter  created
or secured or which now or hereafter relate in any other way to the Obligations.

         3. GUARANTY  ABSOLUTE.  Except to the extend expressly provided herein,
this  Guaranty  shall  in  all  respects  be  an  absolute,   unconditional  and
irrevocable guaranty of payment of the Obligations and Guarantor guarantees that
the Obligations will be paid strictly in accordance with the terms of the Credit
Documents under which they arise, regardless of any law, regulation or order now
or hereafter in effect in any  jurisdiction  affecting  any of such terms or the
rights of Lender with respect  thereto.  The  liability of Guarantor  under this
Guaranty  shall remain in full force and effect without regard to, and shall not
be released, suspended,  discharged,  terminated, modified or otherwise affected
by any circumstance or occurrence  whatsoever,  including without limitation any
of the  following  (whether  or not  Guarantor  consents  thereto  or has notice
thereof):  (i) any change in or waiver of the time,  place or manner of payment,
or any other term, of any of the Obligations or Credit Documents,  any waiver of
or any renewal, extension,  increase,  amendment or modification of or addition,
consent or supplement to or deletion from, or any other action or inaction under
or in  respect  of,  any of the  Obligations  or Credit  Documents  or any other
document,  instrument  or  agreement  referred to therein or any  assignment  or
transfer  of any of the  Obligations  or  Credit  Documents;  (ii)  any  lack of
validity,  legality  or  enforceability  of  any of the  Obligations  or  Credit
Documents or any other document, instrument, or agreement referred to therein or
of any assignment or transfer of any of the  foregoing;  (iii) any furnishing to
Lender of any  additional  collateral  for any of the  Obligations  or any sale,
exchange,  release or surrender of, or realization on, any collateral for any of
the  Obligations;  (iv) any  settlement,  release  or  compromise  of any of the
Obligations or Credit Documents,  any collateral  therefor,  or any liability of
any other party (including  without limitation any other guarantor) with respect
to any of the Obligations or Credit  Documents,  or any subordination of payment
of any of the Obligations to the payment of any other indebtedness, liability or
obligation  of  Borrower;  (v)  any  bankruptcy,   insolvency,   reorganization,
composition,  adjustment,  merger,  consolidation,  dissolution,  liquidation or
other like proceeding or occurrence  relating to Borrower or any other change in
the  ownership,  composition  or nature of  Borrower;  (vi) any  non-perfection,
subordination,  release or voidability of any security interest, security title,
pledge,  collateral assignment or other lien of Lender on any collateral for any
of the  Obligations  or this  Guaranty;  (vii) any  application  of sums paid by
Borrower or any other person with respect to any of the  Obligations,  except to
the extent actually  applied against the  Obligations,  regardless of what other
liabilities of Borrower  remain  unpaid;  (viii) the failure of Lender to assert
any claim or demand or to enforce  any right or remedy  against  Borrower or any
other person (including any other guarantor of any of the Obligations) under the
provisions of any of the Credit Documents or otherwise, or any failure of Lender
to exercise any right or remedy against any other guarantor of or any collateral
for any of the Obligations; (ix) any other act or failure to act by Lender which
may  adversely  affect  Guarantor;  or (x) any other  circumstance  which  might
otherwise  constitute a defense against,  or a legal or equitable  discharge of,
Guarantor's liability under this Guaranty.

         4.  GUARANTY  CONTINUING;  REINSTATEMENT.  This  Guaranty  shall in all
respects be a continuing and irrevocable  guaranty of payment (and not merely of
collection)  and  shall  remain  in  full  force  and  effect  until  all of the
Obligations  shall have been indefeasibly paid in full and Lender shall be under
no obligation to make any additional  loans or extend any  additional  credit or
financial  accommodations  to Borrower which would  constitute  Obligations once
made or extended. If claim is ever made upon Lender for repayment or recovery of
any  amount  received  by  Lender  in  payment  or on  account  of  any  of  the
Obligations,  and if Lender  repays all or part of said  amount by reason of (i)
any  judgment,  decree  or order  of any  court or  administrative  body  having
jurisdiction  over  Lender  or any of its  property  or (ii) any  settlement  or
compromise  of any  such  claim  effected  by  Lender  with  any  such  claimant
(including without limitation Borrower or a trustee, conservator or receiver for
Borrower),  then and in such  event  Guarantor  agrees  that any such  judgment,
decree,  order,  settlement  or  compromise  shall be  binding  upon  Guarantor,
notwithstanding any revocation or cancellation of this Guaranty or of any of the
Credit  Documents,  and Guarantor shall be and remain liable to Lender hereunder
for the amount so repaid or  recovered  to the same extent as if such amount had
never originally been paid to Lender and Guarantor's obligations and liabilities
to Lender  under  this  Guaranty  shall be  reinstated  to such  extent and this
Guaranty and any  collateral  for this  Guaranty  shall remain in full force and
effect (or shall be  reinstated)  to such  extent.  Guarantor  hereby  expressly
waives the benefit of any applicable  statute of limitations  and agrees that it
shall be liable  under this  Guaranty  whenever  Lender  seeks to  enforce  such
liability against Guarantor or its property.

     5. WAIVERS AND CONSENTS.  Guarantor hereby waives: (i) notice of acceptance
of this Guaranty by Lender; (ii) notice of the creation, existence, acquisition,
extension,  or renewal of any of the Obligations;  (iii) notice of the amount of
the Obligations outstanding from time to time, subject,  however, to Guarantor's
right to make inquiry of Lender at reasonable  intervals to ascertain the amount
of Obligations then outstanding;  (iv) notice of any default or event of default
under any of the Credit  Documents or with respect to any of the  Obligations or
notice of any other adverse change in Borrower's financial condition or means or
ability to pay any of the  Obligations or perform its  obligations  under any of
the  Credit  Documents  or  notice  of  any  other  fact  which  might  increase
Guarantor's  risk hereunder;  (v) notice of presentment,  demand,  protest,  and
notice of  dishonor  or  nonpayment  as to any  instrument;  (vi)  notice of any
acceleration  or other demand for payment of any of the  Obligations;  and (vii)
all other  notices and demands to which  Guarantor  might  otherwise be entitled
with respect to any of the  Obligations or the Credit  Documents or with respect
to Lender's enforcement of its rights and remedies thereunder. Guarantor further
waives any right  Guarantor  may have,  by  statute  (such as  O.C.G.A.  Section
10-7-24) or otherwise, to require Lender to seek recourse first against Borrower
or  any  other  person,  or to  realize  upon  any  collateral  for  any  of the
Obligations,  as a condition  precedent to enforcing  Guarantor's  liability and
obligations  under this  Guaranty,  and  Guarantor  further  waives any  defense
arising by reason of any incapacity or other disability of Borrower or by reason
of any other defense which Borrower may have on any of the  Obligations or under
any of the Credit Documents.  Guarantor consents and agrees that, without notice
to or consent by Guarantor  and without  affecting or impairing the liability of
Guarantor  under this  Guaranty,  Lender may  compromise  or settle,  extend the
period of duration or the time for the payment,  discharge or performance of any
of the Obligations or Credit Documents,  or may refuse to enforce or may release
all  or any  parties  to any  or  all  of  the  Obligations  (including  without
limitation any other guarantor thereof) or any collateral therefor, or may grant
other  indulgences to Borrower or such other parties in respect thereof,  or may
waive,  amend or  supplement  in any manner the  provisions of any of the Credit
Documents or any other document, instrument or agreement relating to or securing
any of the Obligations  (other than this Guaranty),  or may release,  surrender,
exchange,  modify,  or  compromise  any and all  collateral  securing any of the
Obligations  or in which  Lender  may at any time have a lien,  or may refuse to
enforce  its  rights  or may make any  compromise  or  settlement  or  agreement
therefor, in respect of any and all of such collateral, or with any party to any
of the Obligations or Credit Documents, or with any other person, or may release
or  substitute  any one or more of the  other  endorsers  or  guarantors  of the
Obligations  whether parties to this Guaranty or not, or may exchange,  enforce,
waive or release any  collateral  for any  guaranty  of any of the  Obligations.
Guarantor  further  consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of  Guarantor  or against or in payment of any of
the Obligations.

         6.  SUBROGATION  AND OTHER  RIGHTS.  Guarantor  agrees that no payment,
performance or enforcement of Guarantor's liabilities and obligations under this
Guaranty shall cause Guarantor,  by subrogation or otherwise,  to acquire any of
Lender's rights against Borrower or any property of Borrower (or any interest in
such rights) unless and until Lender has received full and indefeasible  payment
of all of the Obligations.

         7. CROSS-COLLATERALIZATION.  Guarantor's obligations and liabilities to
Lender under this Guaranty  shall be secured by any and all security  interests,
security titles, pledges, collateral assignments or other liens which Lender may
now or  hereafter  have or acquire  in, to or on any real or  personal  property
assets of Guarantor,  whether such assets now exist or are  hereafter  acquired,
except to the extent that Guarantor's  obligations and liabilities hereunder are
expressly excluded from the coverage of any such lien under the express terms of
the mortgage,  security deed, security agreement,  pledge agreement,  collateral
assignment or other document which granted or grants such lien.

         8. GUARANTOR DUE DILIGENCE AND BENEFIT. Guarantor is fully aware of the
financial  condition,  assets  and  prospects  of  Borrower,  and  Guarantor  is
executing  and  delivering  this  Guaranty  based  solely upon  Guarantor's  own
independent  investigation  thereof  and in no  part  upon  any  representation,
warranty or statement of Lender with respect to Borrower's  financial condition,
assets or  prospects.  Guarantor  is in a position  to and hereby  assumes  full
responsibility  for  obtaining  any and all  information  concerning  Borrower's
financial condition, assets and prospects as Guarantor may now or hereafter deem
material  to  Guarantor's  decision to enter into and become  liable  under this
Guaranty and Guarantor is not relying upon, nor does Guarantor  expect Lender to
furnish Guarantor with any information which may be now or hereafter in Lender's
possession  concerning  Borrower's  financial  condition,  assets or  prospects.
Guarantor hereby knowingly accepts the full range of risks encompassed  within a
contract of guaranty,  which risks Guarantor  understands  may include,  without
limitation,  the possibility that Borrower may incur additional  indebtedness to
Lender for which Guarantor may be liable  hereunder after  Borrower's  financial
condition  or means or ability  to pay its  lawful  debts when they fall due has
deteriorated. Guarantor further acknowledges and agrees that any credit or other
financial accommodations now or hereafter extended by Lender to Borrower and any
and all forbearances with respect to Borrower or its assets which Lender may now
or hereafter grant are and will be of direct interest,  benefit and advantage to
Guarantor.

         9. LENDER'S  ACCOUNTS AND RECORDS;  APPLICATION OF PAYMENTS.  Guarantor
agrees  that,  in the absence of manifest  error,  any and all books and records
relating to the  Obligations  which are prepared and  maintained by Lender shall
constitute  prima facie evidence of the existence and amount of the Obligations.
In the event that Lender sends to Borrower any periodic or other  statements  of
account  with  respect  to any or all of the  Obligations,  each such  statement
rendered by Lender  shall,  in the absence of manifest  error,  be deemed final,
binding and conclusive  upon Guarantor  unless Lender is notified by Borrower in
writing to the contrary  within  thirty (30) days after the date such  statement
was sent by Lender to  Borrower  (and each such  notice  shall only be deemed an
objection  to  those  items   specifically   objected  to  therein).   Guarantor
irrevocably  waives the right to direct the  application of any and all payments
and  collections at any time  hereafter  received by Lender from or on behalf of
Borrower,  Guarantor or otherwise  with  respect to any of the  Obligations  and
Guarantor  does hereby  irrevocably  agree that Lender shall have the continuing
exclusive  right to apply and re-apply any and all such payments and collections
received at any time hereafter by Lender against the  Obligations in such manner
and order as Lender may deem  advisable,  notwithstanding  any contrary entry by
Lender upon any of its books and records.

         10.  AUTOMATIC   ACCELERATION  OF  GUARANTY.  In  the  event  that  any
proceeding  is  instituted  by or  against  Borrower  under  the  United  States
Bankruptcy Code or any other bankruptcy, receivership, insolvency, or moratorium
law (and, in the case of any such involuntary  proceeding which is not consented
to or  acquiesced  in  by  Borrower  or  Guarantor,  the  continuation  of  such
proceeding  without the same being dismissed or stayed for thirty (30) days), as
between Guarantor and Lender, all of the Obligations shall be deemed immediately
due and payable,  without notice or demand of any kind by Lender,  and Guarantor
agrees  immediately to pay the Obligations in full,  irrespective of whether any
or  all of  the  Obligations  can  then  be  accelerated  against  Borrower  and
irrespective  of any right which  Borrower  then may have under any  bankruptcy,
receivership,  insolvency or  moratorium  law to cure defaults and reinstate the
maturities of the Obligations.

         11.  GUARANTOR  INFORMATION.  Guarantor  agrees  that,  so long as this
Guaranty remains in effect, Guarantor shall furnish to Lender from time to time,
at such  intervals  and by such dates as may be  required  by Lender,  financial
statements for Guarantor in form and substance  satisfactory  to Lender together
with such other information relating to Guarantor's financial condition,  assets
or prospects as Lender may request,  and  Guarantor  shall permit  Lender or its
representatives  to visit and inspect  Guarantor's  properties  and  Guarantor's
books and records during  reasonable  business hours and to discuss  Guarantor's
financial condition, assets, and prospects with Lender.

         12. SET-OFF AGAINST DEPOSITS.  If an event of default shall occur under
any of the Credit Documents,  Lender,  without notice or demand of any kind upon
Guarantor,  may hold and set-off against such of the  Obligations  (whether then
matured or  unmatured)  as Lender may elect any balance or amount in any deposit
or other account of any nature  whatsoever now or hereafter  maintained by or on
behalf of Guarantor  with Lender,  regardless of whether such account is general
or special and regardless of whether such account is individual or joint.

         13. NOTICES TO GUARANTOR. All notices, demands and other communications
hereunder  by Lender to Guarantor  shall be deemed to have been validly  served,
given or  delivered  by  Lender  when  hand-delivered  against  receipt,  or one
business day after being entrusted to a reputable  national  overnight  delivery
service,  or two business days after being  deposited in the United States mail,
postage  prepaid,  or, in the case of a  telegraphic  or telecopy  notice,  when
transmitted,  and in each case directed or addressed to Guarantor at Guarantor's
address  or  telecopy  number set forth  beneath  Guarantor's  signature  below.
Guarantor may designate a different  address or telecopy  number for Guarantor's
receipt of notices or other communications hereunder but no such change shall be
effective unless and until Lender actually  receives written notice thereof from
Guarantor.

         14.  COLLECTION  COSTS.  Guarantor  shall be liable to Lender for,  and
shall  pay  to  Lender  on  demand,  all  costs  (including  without  limitation
reasonable  attorney's  fees  and  expenses)  actually  incurred  by  Lender  in
enforcing performance of or collecting any payments due under this Guaranty.

         15.  ASSIGNMENT  AND  TRANSFER.  This  Guaranty  shall be binding  upon
Guarantor and Guarantor's heirs, legal  representatives,  successors and assigns
and  shall  inure  to the  benefit  of and be  enforceable  by  Lender  and  its
successors,  transferees  and assigns.  Without  limiting the  generality of the
preceding sentence, Lender may assign or grant participations in all or any part
of the Obligations, whereupon such assignee or participant shall become entitled
to all of the rights in respect thereof granted to Lender herein.

         16. GOVERNING LAW. This Guaranty shall be governed by the internal laws
of the State of Georgia (without giving effect to its conflicts of law rules).

         17.  SUBORDINATION  OF  BORROWER'S  OBLIGATIONS  TO  GUARANTOR.  As  an
independent  covenant,  Guarantor hereby expressly  covenants and agrees for the
benefit of Lender  that all  present  or future  indebtedness,  obligations  and
liabilities  of Borrower to Guarantor of whatsoever  description  (collectively,
the "Junior  Claims") shall be subordinate and junior in right of payment to all
Obligations of Borrower to Lender  (collectively,  the "Senior  Claims").  If an
event of default under any Credit Document shall occur,  then,  unless and until
such event of default  shall have been cured or shall have  ceased to exist,  no
direct or  indirect  payment  (in  cash,  property,  securities  by  set-off  or
otherwise) shall be made by Borrower to Guarantor on account of or in any manner
in respect of any Junior  Claim  except  such  payments  and  distributions  the
proceeds  of which  shall be  applied to the  Senior  Claims.  In the event of a
Proceeding (as  hereinafter  defined),  all Senior Claims shall first be paid in
full before any direct or indirect payment or distribution  (in cash,  property,
securities by set-off or otherwise)  shall be made to Guarantor on account of or
in  any  manner  in  respect  of any  Junior  Claim  except  such  payments  and
distributions  the proceeds of which shall be applied to the Senior Claims.  For
the purposes of the previous  sentence,  a "Proceeding"  shall occur if Borrower
shall make an  assignment  for the  benefit  of  creditors,  file a petition  in
bankruptcy, have entered against or in favor of it an order for relief under the
Bankruptcy Code or similar law of any other jurisdiction,  generally fail to pay
its debts as they come due (either as to number or amount), admit in writing its
inability to pay its debts generally as they mature, make a voluntary assignment
for the benefit of creditors,  commence any proceeding  relating to it under any
reorganization,  arrangement,  readjustment of debt,  dissolution or liquidation
law or statute of any  jurisdiction,  whether now or hereafter in effect,  or by
any act,  indicate  its consent  to,  approval  of or  acquiescence  in any such
proceeding or in the appointment of any receiver of, or trustee or custodian (as
defined in the  Bankruptcy  Code) for  itself,  or any  substantial  part of its
property,  or a trustee or a receiver  shall be appointed  for Borrower or for a
substantial  part of the  property of Borrower and such  appointment  remains in
effect for more than sixty (60) days or  Borrower  shall  indicate  its  consent
thereto,  approval  therefor or  acquiescence  therein,  or a petition under any
bankruptcy,  reorganization,  arrangement,  readjustment of debt, dissolution or
liquidation  law or statute of any  jurisdiction  (whether  now or  hereafter in
effect) shall be filed against Borrower and such petition shall not be dismissed
within sixty (60) days after such  filing,  an order for relief shall be entered
in such  proceeding,  or Borrower shall indicate its consent  thereto,  approval
therefor or acquiescence therein. In the event any direct or indirect payment or
distribution is made to Guarantor in contravention of this Section, such payment
or distribution  shall be deemed received in trust for the benefit of Lender and
shall  be  immediately   paid  over  to  Lender  for  application   against  the
Obligations. Guarantor agrees to execute such additional documents as Lender may
reasonably request to evidence the subordination provided for in this Section.

         18.  MISCELLANEOUS.  (a) This Guaranty  (together  with any  collateral
documents  executed  by  Guarantor  to secure its  obligations  and  liabilities
hereunder)  constitutes  the sole and entire  agreement  between  Guarantor  and
Lender with respect to the subject matter hereof and supersedes and replaces any
and all prior agreements, understandings, negotiations or correspondence between
them  with  respect  thereto,  including  without  limitation  any and all prior
guaranty agreements executed by Guarantor in favor of Lender with respect to any
or all of the Obligations.

         (b) This Guaranty is intended to be an instrument  under seal.  Time is
of the essence of this Guaranty.

         (c) Words  importing the singular  number  hereunder  shall include the
plural  number and vice versa and any  pronouns  used herein  shall be deemed to
cover all  genders.  The term  "person"  as used  herein  means any  individual,
corporation, partnership, joint venture, limited liability company, association,
joint-stock  company,  trust or other entity, or any government or any agency or
political subdivision thereof.

         (d)  Wherever  possible,  any  provision  in  this  Guaranty  which  is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be  ineffective  only to the  extent  of such  prohibition  or  unenforceability
without  invalidating the remaining  provisions hereof, and any such prohibition
or  unenforceability  in any one  jurisdiction  shall not  invalidate  or render
unenforceable such provision in any other jurisdiction.

         (e) No  amendment  or waiver of any  provision  of this  Guaranty,  nor
consent to any departure by Guarantor  therefrom,  shall be effective or binding
upon Lender unless Lender shall first have given written  consent  thereto.  Any
such amendment, waiver or consent which is so granted by Lender shall apply only
to the  specific  occasion  which is the  subject of such  amendment,  waiver or
consent and shall not apply to the  occurrence  of the same or any similar event
on any future  occasion.  No failure on the part of Lender to  exercise,  and no
delay by Lender in  exercising,  any right  hereunder  shall operate as a waiver
thereof,  nor  shall any  single  or  partial  exercise  of any right  hereunder
preclude  any other or further  exercise  thereof or the  exercise  of any other
right by  Lender.  No notice to or  demand  on  Guarantor  in any case by Lender
hereunder shall entitle Guarantor to any further notice or demand in any similar
or other  circumstances  or  constitute a waiver of the rights of Lender to take
any other or future action in any  circumstances  without notice or demand.  The
remedies provided to Lender in this Guaranty are cumulative and not exclusive of
any other remedies provided by law.

         (f) This Guaranty, each of the Credit Documents and all other documents
relating  thereto,  including  without  limitation  any  consents,  waivers  and
modifications that may be hereafter executed and delivered with respect thereto,
may be reproduced by Lender by photographic,  photostatic,  microfilm,  or other
similar process and Lender may destroy any original documents so reproduced, and
Guarantor  hereby  stipulates  and  agrees  that,  to the  extent  permitted  by
applicable law, any such reproduction  shall be as admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original shall be in existence and whether or not such  reproduction was made by
Lender in the ordinary course of its business),  and any enlargement,  facsimile
or further  reproduction  of such  reproduction  shall likewise be admissible in
evidence.

         (g) This Guaranty may be executed in one or more  counterparts and each
such counterpart shall constitute an original and all such counterparts together
shall constitute one and the same instrument.

         (h) All Section  headings  herein are for convenience of reference only
and shall not limit or  otherwise  affect the meaning or  interpretation  of the
provisions of this Guaranty.

         (i) If this Guaranty is executed by more than one  Guarantor,  the term
"Guarantor" as used herein shall include all such persons  collectively and each
such person  individually  and all such persons  shall be jointly and  severally
liable under this Guaranty.  If more than one person is named above as Borrower,
the term  "Borrower" as used herein shall include all such persons  collectively
and each such person individually.

         (j) To the maximum extent permitted by law, the Guarantor covenants and
agrees so long as the  Obligations  remain  outstanding  to maintain its primary
depository relationships with Lender.

         19. JURY TRIAL WAIVER;  CONSENT TO  JURISDICTION  AND VENUE.  GUARANTOR
HEREBY  WAIVES,  TO THE FULLEST  EXTENT  PERMITTED BY APPLICABLE  LAW, ANY RIGHT
GUARANTOR MAY HAVE UNDER ANY  APPLICABLE  LAW TO A TRIAL BY JURY WITH RESPECT TO
ANY SUIT OR LEGAL ACTION WHICH MAY BE COMMENCED BY OR AGAINST GUARANTOR,  LENDER
OR BORROWER CONCERNING THE INTERPRETATION,  CONSTRUCTION,  VALIDITY, ENFORCEMENT
OR PERFORMANCE OF THIS GUARANTY OR ANY OF THE CREDIT DOCUMENTS. IN THE EVENT ANY
SUCH SUIT OR LEGAL  ACTION IS COMMENCED BY LENDER,  GUARANTOR  HEREBY  EXPRESSLY
AGREES,  CONSENTS  AND  SUBMITS  TO THE  PERSONAL  JURISDICTION  OF ANY STATE OR
FEDERAL COURT SITTING IN FULTON  COUNTY,  GEORGIA,  WITH RESPECT TO SUCH SUIT OR
LEGAL ACTION,  AND GUARANTOR ALSO  EXPRESSLY  CONSENTS AND SUBMITS TO AND AGREES
THAT VENUE IN ANY SUCH SUIT OR LEGAL  ACTION IS PROPER IN SAID COURTS AND COUNTY
AND  GUARANTOR  HEREBY  EXPRESSLY  WAIVES  ANY AND  ALL  PERSONAL  RIGHTS  UNDER
APPLICABLE  LAW OR IN EQUITY TO  OBJECT  TO THE  JURISDICTION  AND VENUE OF SAID
COURTS AND COUNTY. THE JURISDICTION AND VENUE OF THE COURTS AND COUNTY CONSENTED
AND  SUBMITTED  TO AND AGREED  UPON IN THIS  SECTION ARE NOT  EXCLUSIVE  BUT ARE
CUMULATIVE  AND IN  ADDITION  TO THE  JURISDICTION  AND VENUE OF ANY OTHER COURT
UNDER ANY APPLICABLE LAW OR IN EQUITY.

or at Debtor's other locations (if any) set forth on Schedule 1 attached to this
Agreement,  and Debtor shall not,  without the prior written approval of Secured
Party,  remove any  Collateral  therefrom  except for sales of  Inventory in the
ordinary  course  of  business  and the  disposition  of  obsolete  or  worn-out
Equipment in accordance  with this Agreement and except for the storage of goods
at  locations  other than those shown above or on Schedule 1 attached  hereto if
(i) Debtor gives  Secured Party  written  notice of the new storage  location at
least thirty (30) days prior to storing such  Collateral at such location,  (ii)

loss payee under all property  coverages and as an additional  insured under all
liability  coverages,  in form and amount, with insurers,  and against risks and
liabilities which are satisfactory to Secured Party in all respects,  and Debtor
hereby assigns all such policies and all proceeds  thereof  (including  returned
premiums) to Secured Party, to secure the Obligations, agrees to deliver them to
Secured  Party at its request,  and agrees that Secured Party may make any claim
thereunder,  cancel the  insurance  on default by Debtor,  collect  and  receive

refund or return, and apply such amounts received,  at Secured Party's election,
to replacement of the Collateral or to the Obligations.  Debtor shall not use or

substance satisfactory to Secured Party and in the name of Secured Party as loss

shall be and remain personal property and shall not, by reason of its attachment
or other  connection  to any real  property,  either become or be deemed to be a
fixture or  appurtenance  to such real property and shall at all times be deemed
severable therefrom.

         (t) Debtor  shall permit  Secured  Party (or any person  designated  by
Secured Party) from time to time to inspect the Collateral and to inspect, audit
and make copies of or extracts  from all books and records  maintained  by or on
behalf of Debtor pertaining to the Collateral (including computer records),  all
at such times and places as Secured Party may request from time to time.

     5. POWER OF ATTORNEY.  Debtor hereby agrees that from time to time, without
presentment, notice or demand, and without affecting or impairing in any way the
rights of Secured  Party with  respect to the  Collateral,  the  obligations  of

obligated  to and shall  incur no  liability  to  Debtor or any third  party for
failing to, take any action which Debtor is obligated by this  Agreement to take

addition  to all rights  and  remedies  available  to  Secured  Party  under the
Guaranty  Agreement  or the Third  Restated  Loan  Agreement or any of the other
Financing Documents,  or at law, in equity, or otherwise,  do any one or more of
the following:

         (a)  Secured  Party may  declare  any or all of the  Obligations  to be
immediately  due and payable and foreclose or otherwise  enforce Secured Party's
security  interest in or other lien hereunder on any or all of the Collateral in
any manner permitted by law or provided for in this Agreement.

         (b)  Secured  Party may  recover  from  Debtor all costs and  expenses,
including,  without limitation,  actual and reasonable attorney's fees, incurred
or paid by Secured Party in exercising or enforcing any right,  power, or remedy

by applicable law. Notwithstanding anything herein to the contrary, the Debtor's
liability under this Agreement for the Secured Party's attorney's fees shall not
exceed the attorney's fees actually incurred by the Secured Party.

         (c)  Secured  Party may require  Debtor to  assemble  any or all of the
Collateral and make it available to Secured Party at such place or places as may
be designated by Secured Party.

         (d) Secured Party may enter onto any property  where any  Collateral is
located and take possession thereof with or without judicial process.

         (e) Prior to Lender's disposition of any Collateral,  Secured Party may
store, process,  complete,  repair or recondition it or otherwise prepare it for
disposition in any manner and to the extent Secured Party deems appropriate (but
Secured Party shall not be obligated to do so).

         (f) Secured  Party may  transfer any of the  Collateral  into its name,
notify any account  debtor under or other person  obligated on any Collateral to
make payments  thereunder  directly to Secured Party,  and otherwise  collect or
enforce  payment  of any of the  Collateral  (but  Secured  Party  shall have no
obligation to do any of the foregoing).

         (g)  Secured  Party  may  sell  or  otherwise  dispose  of  any  of the
Collateral at one or more public or private sales at Debtor's or Secured Party's
place of business or any other place or places,  including without limitation at
any  brokers  board or  security  exchange,  in lots or in bulk,  for cash or on
credit,  all as Secured Party,  in its discretion,  may deem  advisable.  Debtor
agrees that seven (7) days' prior written notice from Secured Party to Debtor of
any public sale of any  Collateral  or the date after which any private  sale of
any Collateral will be held shall constitute  reasonable notice thereof and such
sale may be held at such  locations as Secured  Party may designate in each said
notice.  Secured Party shall have the right to conduct any such sale on Debtor's
premises,  without any charge therefor, and any such sales may be adjourned from
time to time in accordance with  applicable law.  Secured Party may purchase all
or any part of the  Collateral  at any public sale or, if  permitted by law, any
private  sale and, in lieu of actual  payment of such  purchase  price,  Secured
Party may set-off the amount of such price against the Obligations.

         (h) Secured Party is hereby  granted by Debtor a license or other right
to use during the term of this Agreement, without charge, any or all of Debtor's
labels, patents,  software,  copyrights,  trade secrets, trade names, trademarks
and advertising  materials,  or any other property of any similar nature,  as it
pertains  to any of the  Collateral,  in  advertising  for sale and  selling any
Collateral or in completing  Debtor's  performance  under or collecting any sums
owing in respect of any  Collateral,  and Debtor's rights under all licenses and
all  franchise  agreements  relating  to any of the  Collateral  shall  inure to
Secured  Party's  benefit to the extent of Secured  Party's  rights,  titles and
interests in or to the Collateral under this Agreement.

         (i) Secured Party also may, without prior notice or demand of any kind,
hold and set-off against such of the Obligations  (whether matured or unmatured)
as Secured  Party may elect any balance of amount to the credit of Debtor in any
deposit,  agency,  reserve,  holdback or other account of any nature  whatsoever
which may be now or hereafter  maintained by or on behalf of Debtor with Secured
Party in any of its offices,  regardless  of whether any such account is general
or special and regardless of whether any such account is individual or joint.

         8. APPLICATION OF PROCEEDS.  (a) All monies and other proceeds received
by  Secured  Party  upon  any  collection,  sale  or  other  disposition  of any
Collateral,  together  with all other  monies  and other  proceeds  received  by
Secured Party hereunder, shall be applied as follows:

                        First,  to the  payment  of  the  reasonable  costs  and
                   expenses of such sale,  collection or other disposition which
                   may have been incurred by Secured  Party,  including  without
                   limitation actual and reasonable  attorney's fees as provided
                   in  Section  7(b)  above and all other  reasonable  expenses,
                   liabilities and advances made or incurred by Secured Party in
                   connection therewith;

                        Second, to the payment of all other Obligations then due
                   in such order as Secured Party may elect; and

                        Third,  after  payment in full of all  Obligations  then
                   due, any surplus then  remaining  from such proceeds shall be
                   paid to Debtor; and

         (b) Debtor  shall  remain  liable to Secured  Party for any  deficiency
owing on the Obligations after the application of the proceeds of the Collateral
as provided above.

         9. INDEMNITY.  Debtor hereby agrees to indemnity Secured Party and hold
Secured Party  harmless  from and against any claim,  liability,  loss,  damage,
expense,  suit,  action or proceeding  which may now or hereafter be suffered or
incurred by Secured Party as a result of Debtor's failure to observe, perform or
discharge Debtor's duties or obligations hereunder or Secured Party's holding or
administering this Agreement or any Collateral unless with respect to any of the
above Secured Party is finally determined to have acted with gross negligence or
to have engaged in willful  misconduct.  Without  limiting the generality of the
foregoing,  this indemnity shall extend to any claims  asserted  against Secured
Party by any person under any environmental,  occupational safety and hazard, or
other  similar  laws,  rules or  regulations  by reason of Debtor's or any other
person's  failure  to  comply  with any such  laws,  rules or  regulations.  The
indemnity  obligations  of Debtor under this Section shall  constitute a part of
the  Obligations  secured  hereunder and shall survive the  termination  of this
Agreement.

         10. MISCELLANEOUS.  (a) Any waiver,  forbearance or failure or delay by
Secured Party in exercising  any of its rights,  powers,  or remedies  hereunder
shall not preclude the further  exercise  thereof,  and every right,  power,  or
remedy of Secured Party  hereunder shall continue in full force and effect until
such  right,  power or remedy is  specifically  waived in a writing  executed by
Secured  Party.  Debtor  waives  any right to require  Secured  Party to proceed
against  any  person or to  exhaust  any  Collateral  or to pursue any remedy in
Secured Party's power.

         (b)  This   Agreement   may  be  executed  in  any  number  of  several
counterparts,  each of which when so executed  shall be deemed to be an original
and all of which  counterparts  taken together shall constitute one and the same
instrument.

         (c) This Agreement  contains the entire agreement between Secured Party
and Debtor with respect to the  Collateral and supersedes and replaces the Prior
Security  Agreement as well as any and all other prior agreements,  commitments,
understandings,   negotiations  or  correspondence  between  them  with  respect
thereto.  If any provision of this Agreement shall be held invalid or prohibited
under applicable law, this Agreement shall be invalid or ineffective only to the
extent of such invalidity or prohibition,  without invalidating the remainder of
this Agreement.

         (d) The  rights,  powers,  and  remedies  of Secured  Party  under this
Agreement shall be in addition to all other rights, powers, or remedies given to
Secured Party by applicable law or by any other agreement,  all of which rights,
powers and remedies  shall be  cumulative  and may be exercise  successively  or
concurrently  without  impairing  Secured Party's security  interest in or other
lien on any of the Collateral.

         (e) All singular  terms used herein  shall  include the plural and vice
versa.  All  pronouns  used  herein  shall be deemed to cover all  genders.  All
headings  used  herein  are for  convenience  of  reference  only and  shall not
constitute a substantive part of this Agreement.

         (f) This  Agreement may not be amended or modified  except by a writing
signed by each of the parties hereto.

         (g) Except as may be otherwise  expressly provided herein, all notices,
requests and demands to or upon any party  hereto  shall be given in  accordance
with the notice provisions of the Third Restated Loan Agreement.

         (h) All rights of Secured Party under this Agreement shall inure to the
benefit of its successors and assigns,  and all obligations of Debtor  hereunder
shall bind its successors, and assigns.

         (i) This  Agreement and all security  interests and other liens granted
or  conveyed  hereunder  shall  remain  in full  force and  effect  and shall be
irrevocable  until such time as (x) no Obligations  are  outstanding and (y) the
Third Restated Loan  Agreement is no longer in effect.  Debtor hereby waives any
right Debtor may have upon payment in full of the Obligations to require Secured
Party to terminate  its security  interest in the  Collateral  or any  financing
statement relating thereto until this Agreement is terminated in accordance with
the foregoing terms.

         (j) This Agreement  shall be construed in accordance  with and governed
by the laws of the State of Georgia  without  giving effect to its choice of law
rules.

         (k) Time is of the essence of this Agreement.

         IN  WITNESS  WHEREOF,  Debtor  and  Secured  Party  have  executed  and
delivered this Agreement,  and Debtor has affixed its seal hereto, as of the day
and year first above set forth.

of August 30, 1996,  between the Borrower and the Lender (the "Loan Agreement").
This opinion letter is delivered  pursuant to Section 605 of the Loan Agreement.
Capitalized terms used and not otherwise defined herein are used herein with the
meanings  ascribed  to  them in the  Loan  Agreement  and in the  Interpretative
Standards  (as  defined  below);  provided,  however,  that in the  event of any
conflict in the  definitions  contained in the Loan  Agreement (on the one hand)
and in the Interpretative  Standards (on the other hand), the definitions in the
Loan Agreement shall control.

         This  opinion  letter is limited  by, and is in  accordance  with,  the
January 1, 1992  edition of the  Interpretative  Standards  applicable  to Legal
Opinions to Third Parties in Corporate Transactions adopted by the Legal Opinion
Committee of the  Corporate  and Banking Law Section of the State Bar of Georgia
(the   "Interpretative   Standards"),   which   Interpretative   Standards   are
incorporated in this opinion letter by this reference.

         In connection with this representation, we have examined fully executed
counterparts  of the  following  documents  (items  (a)  through  (f)  below are
hereinafter referred collectively as the "Credit Documents"):

               (a) The Loan Agreement;

               (b) The Note;

               (c) The Security Agreement;

               (d) The Stock Pledge Agreement;

               (e) The Subsidiary Guaranty executed by the Guarantor;

               (f) The Subsidiary Security Agreement executed by the Guarantor;

               (g)  Acknowledgement  copies of the financing  statements on Form
         UCC-1 (the "Financing  Statements")  under the Uniform  Commercial Code
         (the "UCC") as in effect in the State of Georgia (the "State"),  naming
         the  Borrower  and the  Guarantor,  respectively,  as debtors,  and the
         Lender,  as secured  party,  and filed on  ____________,  1996,  in the
         Office of the Clerk of the Superior Court of Cobb County,  Georgia (the
         "Filing Office");

               (h) Reports of examinations (the "Search Reports"),  dated August
         ___, 1996, and conducted under the Borrower's and the Guarantor's  name
         by  Equifax  Business  Information  Services  (which is an  independent
         contractor and is not affiliated with or supervised by our firm) in the
         federal and state tax lien,  judgment lien and UCC financing  statement
         records of the Filing Office; and

               (i) The other documents and material written agreements listed on
         Schedule I attached hereto.

         In the capacity  described  above, we have also considered such matters
of law and of fact,  together  with such  other  records  and  documents  of the
Borrower and the Guarantor, certificates of officers or other representatives of
the Borrower and the Guarantor, certificates of public officials, and such other
documents  as we have deemed  appropriate  for the  opinions  and  confirmations
herein set forth.

         With your  permission in rendering the opinions and  confirmations  set
forth herein, we have assumed the following,  in addition to the assumptions set
forth in the Interpretative  Standards,  without any investigation or inquiry on
our part:

         (i)   The due  authorization,  execution  and  delivery  of all  Credit
               Documents by all parties thereto (other than the Borrower and the
               Guarantor);

         (ii)  That the Credit Documents  constitute the binding  obligations of
               the parties  thereto  (other than the Borrower and the Guarantor)
               and that each party  thereto  (other  than the  Borrower  and the
               Guarantor)  has all requisite  power and authority to perform its
               respective obligations thereunder;

         (iii) That the only interest,  fees and other charges contracted for or
               to be reserved,  charged,  taken or paid in  connection  with the
               Transaction are those set forth in the Credit  Documents and that
               all such  interest,  fees and charges will be reserved,  charged,
               taken and  applied by Lender  solely as  described  in the Credit
               Documents, and that no interest shall be reserved, charged, taken
               or paid under the Credit  Documents  on unpaid  interest and that
               under no circumstances shall the rate of interest paid or payable
               under the Credit Documents (including any fees, charges, premiums
               or similar amounts which may be characterized as interest) exceed
               5.0%  per  month  (whether  due to  prepayment,  acceleration  or
               otherwise);

         (iv)  The Borrower has, prior to or concurrently with its execution and
               delivery   of  the   Security   Agreement,   rights  in  and  the
               unrestricted  right to convey  the  Collateral  covered  thereby,
               including  that  portion  of such  Collateral  which  constitutes
               property  of a type  (x) in  which  a  security  interest  may be
               granted and  perfected  under the  provisions of Article 9 of the
               UCC and (y) as to which the  federal  laws of the  United  States
               have  not  preempted  the  UCC  with  respect  to  the  validity,
               enforceability,  perfection  or priority  of  security  interests
               therein  (such  portion  of  such  Collateral  being  hereinafter
               collectively  referred  to as  the  "Borrower  UCC  Collateral");
 
         (v)   The Guarantor  has, prior to or  concurrently  with its execution
               and delivery of the Subsidiary Security Agreement,  rights in and
               the unrestricted  right to convey the Collateral covered thereby,
               including  that  portion  of such  Collateral  which  constitutes
               property  of a type  (x) in  which  a  security  interest  may be
               granted and  perfected  under the  provisions of Article 9 of the
               UCC and (y) as to which the  federal  laws of the  United  States
               have  not  preempted  the  UCC  with  respect  to  the  validity,
               enforceability,  perfection  or priority  of  security  interests
               therein  (such  portion  of  such  Collateral  being  hereinafter
               collectively  referred to as the "Guarantor UCC Collateral";  the
               Borrower UCC Collateral  and the Guarantor UCC  Collateral  being
               hereinafter  collectively  referred to as the "UCC  Collateral");

         (vi)  The principal place of business and chief executive office of the
               Borrower and the Guarantor are located in the State;

         (vii) All of the UCC  Collateral  of the Borrower and the  Guarantor is
               situated or located  within the State other than that which is in
               transit to or from such a location or is mobile equipment;

         (viii) The Search Reports are accurate and complete; and

         (ix)  The Financing  Statements give (i) the correct  federal  taxpayer
               identification  number for the debtor  named  thereon  and (ii) a
               correct  address of the secured  party named  thereon  from which
               information  concerning  the  security  interest to be  perfected
               thereby may be obtained.

         The opinions set forth herein are limited to the laws of the State, the
general corporation laws of the State of Florida and any applicable federal laws
of the United States.

         Based  upon  the  foregoing,  and  subject  to  the  other  exceptions,
assumptions and qualifications set forth or incorporated herein by reference, it
is our opinion that:

         1. The Borrower was duly  organized as a  corporation,  and is existing
and in good standing, under the laws of the State of Florida.

         2. The  Borrower  has the  corporate  power to execute  and deliver the
Credit  Documents  to which  Borrower  is a party,  to perform  its  obligations
thereunder, to own and use its Assets and to conduct its business.

         3. The Borrower has duly  authorized  the execution and delivery of the
Credit  Documents  to  which  Borrower  is a party  and all  performance  by the
Borrower thereunder.

         4. The Borrower has duly executed and delivered the Credit Documents to
which it is a party.

         5. The execution  and delivery by the Borrower of the Credit  Documents
to which Borrower is a party do not, and if the Borrower were now to perform its
obligations thereunder such performance would not, result in any:

         (i)   violation of the Certificate of  Incorporation  or By-Laws of the
               Borrower;

         (ii)  violation of any existing federal or State constitution, statute,
               regulation,  rule,  order or law to  which  the  Borrower  or its
               Assets are subject;

         (iii) breach of or default under any material written agreements;

         (iv)  creation  or  imposition  of any  contractual  lien  or  security
               interest  in,  on or  against  the  Borrower's  Assets  under any
               material written agreements (except as contemplated by the Credit
               Documents); or

         (v)   violation  of  any  judicial  or  administrative   decree,  writ,
               judgment or order to which, to our knowledge, the Borrower or its
               Assets are subject.

         With your permission,  we have assumed that the term "material  written
agreements"  used in clauses (iii) and (iv) above includes only those agreements
listed as such on Schedule I attached hereto.

         6. The Guarantor was duly organized as a  corporation,  and is existing
and in good standing, under the laws of the State of Florida.

         7. The  Guarantor  has the  corporate  power to execute and deliver the
Credit  Documents  to which  Guarantor  is a party,  to perform its  obligations
thereunder, to own and use its Assets and to conduct its business.

         8. The Guarantor has duly  authorized the execution and delivery of the
Credit  Documents  to which  Guarantor  is a party  and all  performance  by the
Guarantor thereunder.

         9. The Guarantor  has duly executed and delivered the Credit  Documents
to which it is a party.

         10. The execution and delivery by the Guarantor of the Credit Documents
to which  Guarantor is a party do not, and if the Guarantor  were now to perform
its obligations thereunder such performance would not, result in any:

         (i)   violation of the Certificate of  Incorporation  or By-Laws of the
               Guarantor;

         (ii)  violation of any existing federal or State constitution, statute,
               regulation,  rule,  order or law to which  the  Guarantor  or its
               Assets are subject;

         (iii) breach of or default under any material written agreements;

         (iv)  creation  or  imposition  of any  contractual  lien  or  security
               interest  in, on or  against  the  Guarantor's  Assets  under any
               material written agreements (except as contemplated by the Credit
               Documents); or

         (v)   violation  of  any  judicial  or  administrative   decree,  writ,
               judgment or order to which,  to our  knowledge,  the Guarantor or
               its Assets are subject.

         With your permission,  we have assumed that the term "material  written
agreements"  used in clauses (iii) and (iv) above includes only those agreements
listed as such on Schedule I attached hereto.

         11. No consent,  approval,  authorization or other action by, or notice
to or filing  with,  any court or  administrative  or  governmental  body of the
United  States or the State is required in  connection  with the  execution  and
delivery  by the  Borrower  or the  Guarantor  of the  Credit  Documents  or the
incurrence  by the  Borrower or the  Guarantor of their  respective  obligations
thereunder,  except such consents, approvals,  authorizations,  registrations or
filings as have been made or obtained and are in full force and effect.

         12. Each Credit  Document  executed by the Borrower or the Guarantor is
enforceable against it.

         13.  While the laws of the State  relating to matters of  interest  and
usury  are not  without  ambiguities,  and  assuming  that the  Borrower  is not
required or deemed to pay any interest or other  charges for the use of money in
connection with the Transactions in excess of 5% per month, a court applying the
laws of the State should  conclude  that the Credit  Documents are in compliance
with the State's interest and usury laws; provided,  however, that we express no
opinion  herein as to any provision of any Credit  Document (if any) that may be
construed to require or permit interest to be charged or paid on unpaid interest
except  to the  extent  permitted  under  Official  Code  of  Georgia  Annotated
("O.C.G.A.") Section 7-4-17.

         14. None of the Loans  contemplated  by the Loan  Agreement,  including
without limitation the use of the proceeds thereof,  will violate or result in a
violation  of  Regulation  G, T, U or X of the Board of Governors of the Federal
Reserve System.

         15. (a) Each of the  Security  Agreement  and the  Subsidiary  Security
Agreement  is  effective  to create a security  interest  in the UCC  Collateral
covered thereby;

         (b) The Financing  Statements are in appropriate form for filing in the
State and no taxes or fees,  other than normal  filing fees,  are required to be
paid in connection with such filing, and the filing of the Financing  Statements
is  effective  to perfect the  security  interest to be created by the  Security
Agreement and the Subsidiary Security Agreement,  respectively,  in that portion
of the UCC  Collateral  in which a security  interest  may be  perfected  by the
filing of a UCC financing statement in the State (the "Security Interest");

         (c)  Based  solely  on  the  Search  Reports,  for  which  we  take  no
responsibility, and assuming that no additional filings have been made since the
effective time thereof, the Security Interest has the priority accorded to a UCC
security  interest  perfected by the filing of a UCC financing  statement in the
Filing Office; and

         (d) The opinions  expressed in paragraphs  15(a), (b) and (c) above are
subject to the following additional exceptions and qualifications:

         (i)   The effect of bankruptcy, insolvency, reorganization,  moratorium
               and  other  similar  laws  affecting  the  rights  of  creditors,
               including the U.S. Bankruptcy Code in its entirety and State laws
               regarding  fraudulent  transfers,  obligations and conveyances or
               regarding receiverships;

         (ii)  In the case of  proceeds,  as such  term is  defined  in the UCC,
               continuation of the perfection of the Security  Interest  therein
               is limited to the degree set forth in O.C.G.A. Section 11-9-306;

         (iii) Continuation statements relating to the Financing Statements must
               be filed  within six (6) months prior to the  expiration  of five
               (5) years  from the date of filing  thereof  and  within the same
               period prior to each succeeding  fifth (5th)  anniversary of such
               filing date;

         (iv)  Additional  filings  may be  necessary  with  respect  to the UCC
               Collateral  if the  Borrower or the  Guarantor  changes its name,
               identity or corporate  structure or the jurisdiction in which the
               UCC  Collateral  is located or in the event the  Borrower  or the
               Guarantor changes the location of its principal place of business
               or chief executive office;

         (v)   It may not be possible to create or perfect any security interest
               in any of the UCC  Collateral  consisting  of accounts or general
               intangibles  arising  under service  agreements,  or the proceeds
               thereof,  that are subject to an agreement that is or purports to
               be  non-assignable  or that may not be assigned under  applicable
               law; and

         (vi)  We express no opinion  herein with respect to the  perfection  or
               priority  of the  Security  Interest  in any  portion  of the UCC
               Collateral  which  may  constitute  a  fixture  (as such  term is
               defined in the UCC).

         Based  upon  the  foregoing,  and  subject  to  the  other  exceptions,
assumptions and qualifications set forth or incorporated by reference herein, we
hereby confirm to you that:

         A. To our  knowledge,  no litigation or other  proceedings  against the
Borrower  or the  Guarantor  or any of their  respective  Assets is  pending  or
overtly threatened by a written communication to the Borrower or the Guarantor.

         B. The  Borrower  and the  Guarantor  are each  qualified  to  transact
business  as a foreign  corporation  in the  States of  Georgia.  The  foregoing
statement is based solely upon certificates  provided by an agency of that state
as described on Schedule I attached hereto,  copies of which have been delivered
to you at the closing of the Transaction, and is limited to the meaning ascribed
to such certificate by the applicable state agency.

         This opinion  letter has been  delivered  solely for the benefit of the
addressees  pursuant  to the Loan  Agreement  and may not be relied  upon by any
other  person or entity or for any other  purpose  without the  express  written
permission of the undersigned.

                              Very truly yours,

                               WAIVER AND CONSENT


         THIS WAIVER AND  CONSENT is made as of this _____ day of August,  1996,
by the undersigned in favor of NATIONSBANK,  N.A.  (SOUTH),  a national  banking
association having offices at 600 Peachtree Street, N.E., Atlanta, Georgia 30308
(the "Lender").

                               STATEMENT OF FACTS

         The  undersigned  is  the  lessor  of the  real  property  and  related
improvements  and  fixtures  located at  _______________________________________
hereinafter  collectively  called the "Real Property".  The Lender and CRYOLIFE,
INC.   and/or  its  subsidiary   CRYOLIFE   INTERNATIONAL,   INC.,   hereinafter
collectively  called  "Debtor",  the  lessee  of the Real  Property,  may now or
hereafter enter into one or more security  agreements under which the Lender may
be  granted a  security  interest  in some or all of the  Debtor's  now owned or
hereafter acquired accounts,  contract rights,  general intangibles,  documents,
instruments,  inventory, equipment, machinery, furniture, fixtures and leasehold
improvements  and all  proceeds  of any or all of the  foregoing  as well as all
books and records (including without limitation computer and accounting records)
of  the  Debtor  pertaining  to  any  or  all  of  the  foregoing,   hereinafter
collectively  called  the  "Personal  Property".  Some  or all  of the  Personal
Property will be placed, stored or otherwise located on the Real Property.

         NOW,  THEREFORE,  for and in consideration  of the foregoing  premises,
$5.00 in hand paid by the Lender to the undersigned, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
undersigned does hereby consent and agree in favor of Lender as follows:

                               STATEMENT OF TERMS

         1. The undersigned  consents to and acquiesces in the Debtor's grant of
a security interest in the Personal Property in favor of the Lender.

         2. The undersigned hereby waives,  relinquishes and releases any right,
privilege or power which the undersigned  now has, or may hereafter have,  under
or by virtue of any law or any agreement, instrument or other document, to claim
or assert any right, title or interest in or to the Personal Property, including
without  limitation  any right,  privilege or power to levy or distrain upon the
Personal Property for rent, in arrears, in advance or both.

         3. The Lender may  exercise any rights,  privileges,  options or powers
which it may have with respect to the Personal  Property  without  regard to the
undersigned's  right, title or interest in and to the Real Property,  including,
without limitation,  any right, privilege or option which the Lender may have to
enter upon the Real Property and inspect,  or to take  possession of and remove,
the Personal Property, or any part thereof, pursuant to the terms and conditions
of any  agreement  between  Debtor and the Lender or pursuant to any  applicable
law;  provided,  that Lender shall  reimburse the undersigned for the reasonable
costs of repairing any actual  physical  damage to the Real  Property  caused by
Lender in removing the Personal Property (but Lender shall not be liable for any
other diminution in the value of the Real Property resulting from the removal of
any of the Personal Property therefrom).

         4. If the Lender  elects to take  possession  of all or any part of the
Personal  Property pursuant to the terms of any agreement between Debtor and the
Lender or pursuant to any  applicable  law,  the Lender shall have access to the
Real  Property  for the  purposes of  inspecting,  preserving  or  removing  the
Personal Property and the Lender may, in its discretion and without liability to
the undersigned except as expressly provided below, leave all or any part of the
Personal Property on the Real Property for a period of not more than ninety (90)
days after the Lender takes such possession;  provided, that Lender shall pay to
the  undersigned  pro-rated  rent  (based on the base rent rate then  payable by
Debtor to the undersigned)  for the days that Lender is in actual  possession of
the Real Property if and to the extent that Debtor fails to pay the same.

         5. The  undersigned  agrees to give the Lender prior written notice (at
Lender's  address  set  forth  above or at such  other  address  as  Lender  may
hereafter designate by written notice to the undersigned) of any payment default
by Debtor  under its lease of the Real  Property and Lender shall have the right
(but not the obligation) to cure such payment default within ten (10) days after
Lender's  receipt of such payment default notice and the  undersigned  shall not
terminate  the  Debtor's  lease of the Real  Property on account of such payment
default until Lender's cure right expires.

         6. The validity and enforceability of this Waiver and Consent shall not
be impaired,  diminished,  annulled or affected in any manner  whatsoever by the
modification,  alteration,  extension or renewal of any debt or other obligation

                             COMPLIANCE CERTIFICATE

     This  Certificate  is delivered  pursuant to that certain Third Amended and
Restated Loan Agreement,  dated as of March 30, 1996 (the  Agreement),  by and
between CRYOLIFE, INC., a Florida corporation (the Borrower), and NATIONSBANK,
N.A.  (SOUTH),  a national banking  association (the Lender).  All capitalized
terms used in this  Certificate  which are defined in the  Agreement are used in
this  Certificate  with the same  meanings  given such  terms in the  Agreement.
Unless  otherwise  defined in the Agreement,  all  accounting  terms used herein
shall have the meaning  given such terms  under  generally  accepted  accounting
principles consistently applied (GAAP).

     I  hereby  certify,  to the  best  of my  knowledge  and  belief  and in my
representative capacity on behalf of the Borrower, to the Lender as follows:

     1. I am the duly  qualified  and  acting  chief  financial  officer  of the
Borrower.

     2. I have prepared or reviewed the financial  statements of the Borrower as
of and for the period ending  _________________________,  _____, true,  complete
and correct copies of which are attached hereto as Exhibit 1 (collectively,  the
Financial Statements).

     3. The  Financial  Statements  were  prepared in  accordance  with GAAP and
fairly present the financial  position and results of operations of the Borrower
(and its consolidated  subsidiaries,  if any) as of and for the period ending on
the date of the Financial Statements (subject to normal year-end adjustments).

     4. I further  certify that as of, and for the period ending on, the date of
the Financial  Statements,  and except as may be disclosed on Exhibit 2 attached
hereto (all of the following  being  calculated on a  consolidated  basis and in
accordance with GAAP and the Agreement):

               (a) The Borrowers  Current Ratio was not less than 2.0 to 1.0 at
          any time during such period;

               (b) The  Borrowers  Leverage  Ratio did not exceed 1.0 to 1.0 at
          any time during such period;

               (c) The  Borrowers  Debt Coverage Ratio was not less than 1.3 to
          1.0 for such period;

               (d)  The   Borrowers   Net  Worth  was  not  less  than  [insert
          $15,500,000  thru 12/31/96,  and during each fiscal year  thereafter
          insert the prior fiscal years  required  amount plus $500,000] at any
          time during such period; and

               (e) The Borrowers Capital  Expenditures for such fiscal year (or
          for the  portion  thereof  ending  with such  period)  did not  exceed
          $2,000,000 in total.

     Attached hereto as Exhibit 3 are calculations  demonstrating whether or not
the Borrower was in  compliance,  as of and for the period ending on the date of
the Financial  Statements,  with the covenants in the Loan  Agreement  which are
summarized in items (a) through (e) above.

     5. No Default or Event of Default has occurred and is  continuing as of the
date of this  Certificate  other than those  Defaults or Events of Defaults  (if
any) which are described on the aforesaid Exhibit 2 attached hereto.

     I represent the foregoing information to be true and correct to the best of
my knowledge  and belief and I execute  this  Certificate  in my  representative
capacity on behalf of the Borrower as of this ____ day of _____________________,
_____.
