                               SUBLEASE AGREEMENT

This  SUBLEASE  (the  "Sublease")  is entered into as of the 9th day of October,
2000, between IDEAS FOR MEDICINE,  INC., formerly known as CryoLife  Acquisition
Corporation,  a Florida  corporation  (herein called "IFM") and HORIZON  MEDICAL
PRODUCTS, INC., a Georgia corporation (herein called "Horizon"),  both hereafter
called the "Parties".

1.   DEMISE

IFM hereby  sublets to  Horizon  and  Horizon  subleases  from IFM the  Premises
described in Paragraph 2 herein, which is the Demised Premises leased by IFM, as
Tenant, from Secret Promise, Ltd., as successor-in-interest to J. Crayton Pruitt
Family Trust u/t/a 9/17/76, ("Landlord") under that certain lease dated March 5,
1997, as amended,  which is  incorporated  herein,  by  reference,  and which is
hereinafter,  collectively  with  any and  all  amendments,  referred  to as the
"Lease."  Defined terms used herein but not otherwise  defined herein shall have
the meaning set forth in the Lease.

2.   DESCRIPTION OF SPACE

The premises (the "Premises")  subject to this Sublease consists of that certain
tract or parcel of land more particularly described on Exhibit A attached hereto
and made a part hereof,  together with all improvements  erected thereon and all
appurtenances thereunto belonging.

3.   TERM OF SUBLEASE

The term (the "Sublease  Term") of this Sublease shall be for a period ending on
the date that the Lease  Term  expires  or is earlier  terminated,  if  earlier.
Notwithstanding  anything to the contrary  expressed or implied in this Sublease
or in the Lease,  Horizon hereby  acknowledges  and agrees that it shall have no
right to exercise any election,  right or  opportunity of Tenant under the Lease
to renew or extend the term of the Lease,  nor shall  Horizon  have any right to
holdover or continue in  occupancy  of the  Premises  after  termination  of the
Lease,  except as expressly set forth herein to the contrary.  At the expiration
of the initial  Term of the Lease,  Horizon  shall be entitled to request IFM to
extend  the Term of the Lease in  accordance  with the terms of Section 5 of the
Lease. Horizon shall provide such request to IFM in writing not more than ninety
(90) nor less  than  thirty  (30)  days  prior to the last  date by which IFM is
permitted to provide to Landlord a notice of election to extend under the Lease.
If IFM refuses to so extend it shall so notify  Horizon within fifteen (15) days
after receipt of Horizon's notice, and then, with Landlord's prior consent,  and
provided that Landlord agrees in writing that (i) IFM is or shall be released as
of the  expiration  of the then  current  Lease  Term and shall not be or remain
liable during the succeeding  Extension Option Term or Terms, and (ii) CryoLife,
Inc.  ("CryoLife"),  IFM's sole  shareholder,  is or shall be released  from its
obligations  under the  Guaranty  executed  by  CryoLife in favor of Landlord in
connection  with the Lease as of the  expiration  of the then current Lease Term
and shall not be liable during the  succeeding  Extension  Option Term or Terms.
IFM shall  assign all of its right,  title and  interest in and to the Lease and
the Premises to Horizon upon the  expiration or  termination of the then current
Lease Term. Alternatively, if IFM does not elect to extend then Horizon shall be





free to negotiate with Landlord for a new, direct lease of the Premises. Horizon
hereby  acknowledges  that IFM has no duty or obligation to extend the lease for
the benefit of Horizon,  that  Landlord has no duty or  obligation  to negotiate
with  Horizon with respect to a new lease,  and that  Landlord's  consent to any
assignment to Horizon may be granted or withheld by Landlord in accordance  with
the provisions of Section 23 of the Lease.

4.   SUBLEASE RENT

Horizon  agrees to pay to IFM as "Rent" for the  Premises all amounts due by IFM
to Landlord under the Lease including, but not limited to, monthly "Base Rental"
(as  defined  and  prescribed  in the  Lease),  together  with any and all other
"Additional  Rental",  rents,  sums and other  charges due and payable under the
Lease as set forth therein. With respect to Base Rental payments and any and all
other  payments  due on or  before  the first  (1st) day of the month  under the
Lease,  under this Sublease such  payments  shall be due and payable  monthly in
advance on the twentieth (20th) day of each calendar month immediately preceding
the calendar  month of the term of this Sublease for which such Rent is due. The
payment  of Rent for the month of October  2000 shall be due and  payable as and
when this Sublease is executed by Horizon,  and shall be pro rated on a per diem
basis for the partial  month.  As to any and all other  payments due and payable
under the Lease,  for purposes of this Sublease  such payments  shall be due and
payable  to  Horizon  to IFM on the date  which is ten  (10)  days  prior to the
applicable due date for such payment under the Lease.

If any  payment  or  installment  of Rent is not paid as and when due under this
Sublease, and if such failure is not cured within ten (10) days thereafter, then
such Rent payment shall be due and payable together with an administrative  late
charge  handling  fee equal to One Hundred  Dollars  ($100.00).  Horizon  hereby
acknowledges  and agrees that (i) IFM shall not be  obligated to accept any late
payment,  (ii) IFM  shall  not be deemed  to have  waived  such  late  charge by
acceptance  of any  subsequent  Rent payment which fails to include such charge,
and (iii) any and all past due Rent shall,  in addition,  bear interest from the
date  which is ten (10)  days  after  the date due until the date paid at a rate
("Default  Interest Rate") equal to the lesser of eighteen  percent (18%) simple
interest per annum or the highest rate allowed by law.

5.   HOLDOVER

There shall be absolutely no holdover  permitted by Horizon after the expiration
or  termination  of this  Sublease.  Any holdover  after the  expiration of this
Sublease  concurrently  with the  expiration  of the term of the Lease  shall be
conclusively deemed to be as a tenant at will or at sufferance of Landlord under
the Lease,  and not by, through or under IFM under this  Sublease.  Any holdover
after the earlier  termination  of the term hereof  prior to the  expiration  or
termination  of the term of the Lease  shall be  conclusively  deemed to be as a
tenant at will or at  sufferance of IFM under this  Sublease.  Any such holdover
tenancy under  Landlord may  thereafter be terminated by Landlord,  and any such
holdover tenancy under IFM may be thereafter terminated by IFM, at any time from
and after the date it  commences  and/or as provided by the laws of the State of
Florida.  Notwithstanding  the  foregoing,  the Rent  during  the  period of any
holdover  under IFM shall  increase to one hundred  twenty-five  percent  (125%)
times the Rent due payable under the Lease. Further, Horizon hereby acknowledges
and agrees that its indemnity of IFM and of Landlord under Section 6 below shall


                                       2


include,  without  limitation,  any and all claims,  demands,  causes of action,
damages,  costs and expenses  (including  without  limitation  reasonable actual
attorneys'  fees and costs)  arising out of or resulting  directly or indirectly
from Horizon's  holdover.  Notwithstanding  the foregoing,  Horizon shall not be
liable  to IFM  for any  consequent,  special,  indirect,  or  punitive  damages
hereunder,  except to the extent  that  damages (if any) owed by IFM to Landlord
may be so characterized.

6.   HORIZON TO COMPLY WITH LEASE AGREEMENT TERMS, INDEMNITIES

     6.1 Horizon  agrees to perform and observe the covenants,  conditions,  and
terms  set  forth in the Lease on the part of the  tenant  to be  performed  and
observed  (including  without  limitation  Sections  9-11  thereof),  except the
covenant  for the  payment of Base  Rental  (and any rent tax  imposed  thereon)
reserved in the Lease,  and to indemnify,  defend (using counsel  selected by or
acceptable  to IFM for such purpose) and hold the Landlord and IFM each harmless
from and against any and all claims,  demands,  causes of action, damages, costs
and expenses (including without limitation reasonable actual attorneys' fees and
costs) arising out of or resulting  directly or indirectly  from IFM's breach of
or default under the Lease or this Sublease, unless caused by or resulting from,
directly or indirectly, any act or omission, breach or default of Horizon.

7.   SERVICES AND UTILITIES

Horizon shall pay any and all charges for utilities and services as set forth in
the Lease. In the event that IFM has any utility  deposits or other deposits for
services,  Horizon shall  reimburse IFM for the amounts thereof or shall replace
the same with deposits  funded by Horizon  within thirty (30) days after written
request from IFM to do so.

8.   USE FOR BUSINESS PURPOSES

The premises  subleased herein are to be used for the business  purposes set out
in the Lease and for no other use or purpose whatsoever.

9.   ALTERATIONS

Horizon  shall  not  undertake  or  commence  any   alterations,   additions  or
improvements  to the Premises  without  having first  obtained the prior written
consent of IFM hereunder and, to the extent applicable,  the consent or approval
of Landlord under the Lease.

10.  WAIVER OF ONE BREACH NOT WAIVER OF OTHERS

Waiver of one breach of a term,  condition,  or  covenant  of this  Sublease  by
either party hereto shall be limited to the particular instance and shall not be
deemed to be a waiver of future breaches of the same or other terms, conditions,
or covenants.

                                       3

any of the following acts, events or conditions:

under this  Sublease is not paid when due,  and such failure is not cured within
ten (10) days  after  written  notice  from IFM to  Horizon  thereof  (provided,
however,  that IFM shall not be obligated to provide to Horizon a notice of such
failure to the  opportunity  to cure same after such  notice more than three (3)
times in any period of twelve (12) consecutive months;

     (c) The  failure or refusal of  Horizon,  at any time  during the  Sublease
Term,  to fulfill or perform any other  covenant,  agreement  or  obligation  of
Horizon  hereunder if such failure or refusal shall continue without  correction
for a period of twenty  (20) days after  notice  thereof  to Horizon  (provided,
however, that if such covenant,  agreement or obligation shall be of such nature
that it can be fulfilled or performed and if Horizon in good faith  commences to
fulfill or perform  same  within  said  twenty  (20) day period  exercising  due
diligence,  a default by Horizon shall not be deemed to have occurred if Horizon
commences to diligently  pursue the  fulfillment or performance of the covenant,
agreement  or  obligation   during  such  20-day  period  and  shall  thereafter
continuously and diligently proceed therewith until completion within sixty (60)
total days);

     (d) An attempt to assign, sub-sublease or further transfer Horizon's rights
or interests  hereunder  shall occur without the prior written  approval of IFM,
except as set forth in that certain Assignment of Sublease of even date herewith
among Horizon, Bank of America, N.A., and IFM.

     (e) The  initiation of any  proceeding  whereupon the estate or interest of

jurisdiction in the Premises in respect of Horizon in an involuntary  case under

applicable federal or state bankruptcy,  insolvency or other similar law, or the
appointment   of  a  receiver,   liquidator,   assignee,   custodian,   trustee,
sequestrator (or similar official) of Horizon or for any substantial part of the
assets  of  Horizon,  or the  entry of any  decree  or  order  with  respect  to
winding-up or liquidation of the affairs of Horizon, if any such decree or order
continues unstayed and in effect for a period of sixty (60) consecutive days;

     (g) The  commencement  by Horizon  of a  voluntary  case under the  federal
bankruptcy  laws,  as now or  hereafter  constituted,  or any  other  applicable
federal or state bankruptcy,  insolvency or other similar law, or the consent by


                                       4


Horizon to the appointment of or possession by a receiver, liquidator, assignee,
trustee,  custodian,  sequestrator (or other similar official) of Horizon or for
any substantial part of the assets of Horizon, or any assignment made by Horizon
for the  benefit of  creditors,  and such case or  proceeding  is not  dismissed
within sixty (60) days; or

     (h) A default by Horizon under that certain Promissory Note from Horizon in
favor  of IFM  dated  as of  even  date  herewith  in the  principal  amount  of
$5,945,216  (as that note may be amended or replaced) and a failure to cure such
default as set forth therein.

     11.2 Upon the  occurrence  of a default  by Horizon  as  described  in this
Sublease,  IFM shall have the option to pursue any one or more of the  following
remedies  without  notice or demand  whatsoever,  and in addition to, and not in
limitation  of any other remedy or right  permitted to it by law of in equity or
by this Sublease:

     (a) IFM, with or without terminating this Sublease and without waiving such
default,  may perform,  correct or repair any condition which shall constitute a
failure on Horizon's part to keep,  observe,  perform or satisfy such condition,
and IFM may take, on behalf of Horizon,  whatever  steps IFM deems  necessary to
cure such default.  IFM may reenter the Premises for such purposes without being
liable for  prosecution  or any claim for damages  therefor,  and Horizon  shall
fully reimburse and compensate IFM on demand for all costs and expenses incurred
by IFM in such performance,  correction or repair, including without limitation,
accrued  interest  from the date of demand  until date of payment at the Default
Interest Rate, and such sums shall be deemed to be Additional Rental hereunder;

     (b)  IFM  may  terminate  this  Sublease,  in  which  event  Horizon  shall
immediately  surrender  the Premises to IFM, and if Horizon  fails to do so, IFM
may,  without  prejudice  to any other  remedy it may have,  enter upon and take
possession of the Premises and expel or remove  Horizon and any other person who
may be  occupying  said  premises  or any part  thereof in  accordance  with all
applicable laws and without breaching the peace;

     (c) IFM may recover possession of the Premises, with or without terminating
this  Sublease,  at IFM's option,  in the manner  prescribed  by any  applicable
statute, including without limitation, statutes relating to summary process. Any
demand for the Rent,  reentry for conditions  broken, and any and all notices to
quit,  including  without  limitation,  the notice required by the provisions of
Section 83.20, Florida Statutes,  or any similar statutes,  or other formalities
of any nature, to which Horizon may be entitled, are hereby specifically waived.
In any  possessory  action for nonpayment of Rent or other charge due hereunder,
Horizon expressly waives any defense other than payment. Horizon's obligation to
pay Rent is independent of any duty or obligation of IFM under this Sublease;

     (d) IFM may relet the Premises upon such terms and  conditions and for such
rental as IFM deems  advisable,  without  thereby  avoiding or terminating  this
Sublease, and Horizon shall remain liable for any and all Rent and other charges
and expenses hereunder.  For the purpose of reletting, IFM is authorized to make
such repairs or alterations to the Premises  and/or to remove or store Horizon's
or other  occupants'  possessions as may be necessary in the sole  discretion of
IFM for the purpose of such  reletting,  and if a sufficient sum is not realized
from such  reletting  (after  payment of all costs and expenses of such repairs,
alteration or storage and the expense of such  reletting  and the  collection of


                                       5


rent accruing  therefrom)  each month to equal the Rent,  then Horizon shall pay
such deficiency each month upon demand therefor. Actions to collect such amounts
may be  brought  from  time to  time,  on one or  more  occasions,  without  the
necessity of IFM's  waiting until the  expiration  of the Sublease  Term. In the
event of termination of the Sublease or repossession of the Premises for default
as described in this Sublease, IFM shall use commercially  reasonable efforts to
relet the Premises, or a portion thereof, and to collect rental after reletting;
and in the event of  reletting,  IFM may relet the whole or any  portion  of the
Premises,  as agent for Horizon or for IFM's own account,  for any period to any
sublease and for any use and purpose;

     (e) IFM may declare  immediately  due and payable  the then  present  value
(calculated  with a  discount  factor or eight  percent  (8%) per  annum) of the
difference  between (x) the entire amount of Base Rental.  Additional Rental and
other charges and  assessments  which in IFM's  reasonable  determination  would
become due and payable during the remainder of the Sublease Term (in the absence
of the termination of this Sublease),  and (y) the then fair market value of the
Premises for the remainder of the Sublease Term.  Upon the  acceleration of such
amounts, Horizon agrees to pay the same at once, in addition to all Rent, costs,
charges,  assessments,  and reimbursements  theretofore due: provided,  however,
that such  payment  shall not  constitute  a penalty  or  forfeiture,  but shall
constitute liquidated damages for Horizon's failure to comply with the terms and
provisions of this Sublease (IFM and Horizon  agreeing that IFM's actual damages
in such event are  difficult to ascertain and that the amount set forth above is
a reasonable  estimate  thereof).  In computing such liquidated  damages,  there
shall be added to such  deficiency any  reasonable  expenses as IFM may incur in
connection with reletting,  such as court costs,  reasonable attorneys' fees and
disbursements,   brokerage  fees  and  preparing  the  Premises  for  reletting.
Furthermore,  such amount  shall be construed  as  liquidated  damages and shall
constitute a debt provable in bankruptcy or receivership; and/or

     (f) Alter all locks and other  security  devices  at the  Premises  without
terminating this Sublease.

     In the event that IFM shall have taken possession of the Premises  pursuant
to the authority herein granted,  then IFM shall have the right to keep in place
and use all of the furniture,  fixtures and equipment at the Premises, including
without  limitation  that which is owned by or subleased to Horizon,  and at all
times prior to any  foreclosure  thereon by IFM or  repossession  thereof by any
lessor  thereof or third party  having a lien  thereon.  IFM shall also have the
right to remove from the Premises (without the necessity of obtaining a distress
warrant,  writ of  sequestration  or other legal  process) all or any portion of
such furniture, fixtures, equipment and other property located thereon and place
same in storage at any  premises  within  the  county in which the  Premises  is
located; and in such event, Horizon shall be liable to IFM for costs incurred by
IFM in connection with such removal and storage and shall indemnify and hold IFM
harmless from all loss,  damage,  cost, expense and liability in connection with
such removal and storage. IFM shall also have the right to relinquish possession
of all or any portion of such furniture,  fixtures, equipment and other property
to any person  ("Claimant")  claiming to be entitled to  possession  thereof who
presents to IFM a copy of any instrument  represented to IFM by Claimant to have


                                       6


been executed by Horizon (or any predecessor of Horizon)  granting  Claimant the
right  under  various  circumstances  to  take  possession  of  such  furniture,
fixtures,  equipment or other property, without the necessity on the part of IFM
to  inquire  into  the  authenticity  of said  instrument's  copy  of  Horizon's
signature thereon and without the necessity of IFM's making any investigation or
inquiry as to the  validity of the  factual or legal  basis upon which  Claimant
purports to act.  Horizon  agrees to indemnify  and hold IFM  harmless  from all
costs,  expense,  loss, damage and liability incident to IFM's relinquishment of
possession of all or any portion of such furniture, fixtures, equipment or other
property to  Claimant.  The rights of IFM herein  stated shall be in addition to
any and all  other  rights  which  IFM  has or may  hereafter  have at law or in
equity, and Horizon stipulates and agrees that the rights herein granted IFM are
commercially reasonable. IFM shall in no event be liable to Horizon,  including,
without  limitation,  liability for trespass or conversion,  with respect to any
actions  taken  pursuant  to this  Section  11.2 so long as same  are  taken  in
accordance with all applicable laws.

         11.3 No course of dealing  between  IFM and  Horizon or any  failure or
delay on the part of IFM in  exercising  any  rights of IFM under  Section  11.2
hereof or under any other  provisions of this Sublease shall operate as a waiver
of any  rights  of  IFM  hereunder,  at law or in  equity  or  under  any  other
provisions of this  Sublease,  nor shall any waiver of a default on one occasion
operate  as a waiver  of any  subsequent  default  or of any other  default.  No
express waiver shall affect any condition,  covenant,  rule, or regulation other
than the one  specified in such waiver and that one only for the time and in the
manner specifically stated. The exercise by IFM of any one or more of the rights
and remedies provided in this Sublease shall not prevent the subsequent exercise
by IFM of any one or more of the other rights and remedies herein provided.  All
remedies  provided for in this Sublease are  cumulative and may, at the election
of IFM, be exercised alternatively, successively, or in any other manner and are
in addition  to any other  rights  provided  for or allowed by law or in equity.
After  default,  the  acceptance of Rent (or any portion  thereof) or failure to
re-enter by IFM shall not be held to be a waiver of its rights to terminate this
Sublease or of any other rights under this  Sublease or applicable  statue,  and
IFM may  re-enter and take  possession  of the  Premises,  or exercise any other
right and remedy, as if no Rent had been accepted after such default.

         11.4  Exercise by IFM of any one or more  remedies  under Section 11 or
otherwise  available shall not be deemed to be an acceptance of surrender of the
Premises  by Horizon  whether by  agreement  or by  operation  of law,  it being
understood that such surrender can be effected only by the written  agreement of
IFM and Horizon or  otherwise as  permitted  by law. No  alteration  of locks or
other security  devices and no removal or other exercise of dominion by IFM over
the property of Horizon or others at the Premises  shall be deemed  unauthorized
or constitute a conversion, Horizon hereby consenting, after any default, to the
aforesaid  exercise of dominion over Horizon's  property  within the Premises so
long  as  IFM  complies   with  all  Florida  laws   pertaining   to  distraint,
dispossessory,  detainer or other remedial actions of landlords not waived under
this  Sublease.  All  claims  for  damages  by  reason of such  re-entry  and/or
repossession  and/or  alteration of locks or other  security  devices and hereby
waived,  as are all  claims  for  damages  by  reason of any  distress  warrant,
forcible detainer proceedings,  sequestration proceedings or other legal process
so  long  as IFM  complies  with  all  Florida  laws  pertaining  to  distraint,
dispossessory,  detainer or other remedial actions of landlords not waived under
this Sublease. No such reentry or taking possession of the Premises by IFM shall


                                       7


be construed as an election on IFM's part to terminate this  Sublease,  unless a
written  notice of such  intention  be given by IFM to  Horizon  or  unless  the
termination  thereof be decreed by a court of  competent  jurisdiction.  Horizon
agrees that any re-entry by IFM which is made pursuant to a judgment obtained in
forcible  detainer  proceedings  or other  legal  proceedings  will not make IFM
liable for trespass.

12.  LITIGATION COSTS

If any legal action is filed to enforce this Sublease,  or any part thereof, the
prevailing shall be entitled to recover  reasonable  actual  attorneys' fees and
costs of the action.

13.  APPLICABLE LAW, VENUE, AND SERVICE

In interpreting  this Sublease and in determining the right of the Parties under
it, the laws of the State of Florida shall apply.  Venue shall lie in the county
in which the Premises is located.

Personal service either within or without such state shall be sufficient to give
personal jurisdiction to any court in which an action is filed for litigation of
rights under this Sublease.

14.  SURRENDER OF PREMISES AND KEYS

Horizon agrees that at the  expiration or termination of this Sublease,  it will
quit and  surrender the Premises in the condition set forth in the Lease upon an
expiration  or  termination,  without  notice,  and will deliver to IFM all keys
belonging to the Premises.

15.  REMOVAL OF PROPERTY BY IFM

If IFM  re-enters  the  Premises  or  takes  possession  of them  before  normal
expiration of this Sublease in accordance  with its terms,  any and all personal
property  of  Horizon  not  removed  within  ten (10) days of such  re-entry  or
repossession  (and to the  extent IFM has  changed  the  locks,  it will  permit
Horizon access to the Premises for such purposes) shall be  conclusively  deemed
to have been abandoned by Horizon and IFM shall have the right to cause the same
to be removed and disposed of in any manner it deems  necessary or  appropriate,
including without limitation  throwing the same away, at Horizon's sole cost and
expense.

16.  HORIZON'S INSOLVENCY, BANKRUPTCY, RECEIVERSHIP OR ASSIGNMENT FOR CREDITORS

If IFM cannot  terminate this Sublease or Horizon's right of possession  because
of the application of bankruptcy or similar laws,  then Horizon,  as a debtor in
possession  or on behalf of any  trustee  for  Horizon,  shall:  (i)  within the
statutory time,  assume or reject this Sublease and (ii) not seek or request any
extension of adjournment of any application to assume or reject this Sublease by
IFM.  In such  event,  Horizon or any  trustee  for Horizon may only assume this
Sublease if (A) it cures or provides  adequate  assurance  that it will promptly
cure any default  hereunder,  (B) it compensates or provides adequate  assurance
that it will  promptly  compensate  IFM for  any  actual  pecuniary  loss to IFM


                                       8


resulting from Horizon's defaults, including without limitation accrued interest
at the Default  Interest Rate and  attorneys'  fees as a result of such default,
and (C) it provides adequate  assurance or performance  during the Sublease Term
of all of the terms,  covenants and  provisions of this Sublease to be performed
by  Horizon.  In no event  after  the  assumption  of this  Sublease  shall  any
then-existing  default  remain  uncured for a period in excess of the earlier of
ten (10)  days or the time  period  set  forth  herein.  Adequate  assurance  of
performance shall include,  without  limitation,  adequate  assurance (1) of the
source of payment of Rent  reserved  hereunder,  and (2) that the  assumption of
this  Sublease  will not breach any  provision  hereunder,  and will not cause a
breach of any other sublease,  financing  agreement or master agreement relating
to the Building.

deemed to have given its  consent) to the  proposed  Transfer  for all  purposes
under the Lease, (iii) provided that Bank of America,  N.A.  ("Bank"),  is still

attached as Exhibit A to that certain "Lessor  Subordination  and Consent" being
executed and  delivered  substantially  of even date herewith by IFM in favor of
Bank,  then this condition (iv) shall not be applicable).  Horizon  acknowledges

of any proposed  Transfer.  Horizon agrees to give IFM at least thirty-five (35)
days' prior written notice of any proposed Transfer,  and to provide to Landlord
and to Bank a concurrent  copy of any notice  given by Horizon to IFM  hereunder
