may borrow and repay and  reborrow up to a maximum  aggregate  principal  amount
outstanding at any one time equal to the original  principal  amount of the Line
of Credit.

                                        5





All  proceeds so obtained  under the Line of Credit may be used by Borrower  for
general corporate  purposes in such manner as Borrower may elect in the ordinary
course of its business  operations.  All advances to Borrower  under the Line of
Credit  shall be evidenced  by the Note,  which shall be executed and  delivered
simultaneously  herewith.  Each  request for an advance  under the Note shall be
made by  Borrower to Lender in writing no later than 9:00 a.m.  Eastern  time on
the Business Day that is two  Business  Days prior to the date of the  requested
advance.  Lender  shall make the amount of the  requested  advance  available to
Borrower  prior to 1:00 p.m.  Eastern time on the requested  borrowing  date, by
transferring  to the account  directed by Borrower  the amount of the  requested
advance.  The  outstanding  principal  amount of the Note shall be repaid on the
Maturity  Date  or at such  earlier  time as may be  provided  pursuant  to this
Agreement and shall bear interest paid on the first day of each month  (computed
on the  daily  outstanding  principal  balance,  for the  actual  number of days
outstanding,  on the basis of a 365 day year),  payable in the manner  described
therein,  from the date thereof on the unpaid principal amount thereof from time
to time  outstanding at a rate per annum equal to the Prime Rate plus .50%, with
any change in such  interest  rate on the Note due to a change in the Prime Rate
to become  effective  as of the  opening of  business on each date on which such
change in the Prime Rate  occurs.  Notwithstanding  any other  provision of this
Agreement, Lender shall not be required to advance funds to Borrower pursuant to
the Line of Credit  in excess of the  amounts  received  by Lender  pursuant  to
Section  [7.7] of the OpCo  Contribution  Agreement,  dated  January  __,  1997,
between  Lender and Crescent Real Estate  Equities  Limited  Partnership,  which
amounts consist of accounts receivable owned by Lender and collected by Borrower
on Lender's behalf.

                  2.2.  Interest and Charges.  Lender and Borrower  hereby agree
that the only  charge  imposed by Lender upon  Borrower  for the use of money in
connection  herewith is and shall be the interest  expressed in the Note, at the
rate set  forth  therein,  and that all other  charges  imposed  by Lender  upon
Borrower in connection herewith, including, without limitation, default and late
charges,  are and shall be deemed to be charges  made to  compensate  Lender for
underwriting and administrative services and costs, and other services and costs
performed  and  incurred,  and  to be  performed  and  incurred,  by  Lender  in
connection with the Line of Credit,  and shall under no  circumstances be deemed
to be charges for the use of money. In no contingency or event  whatsoever shall
the  aggregate of all amounts  deemed  interest  hereunder or under the Note and
charged or collected  pursuant to the terms of this Agreement or pursuant to the
Note  exceed  the  highest  rate  permissible  under  any law  which a court  of
competent jurisdiction shall, in a final determination,  deem applicable hereto.
In the event that such a court  determines  that  Lender has charged or received
interest  hereunder in excess of the highest applicable rate, the rate in effect
hereunder  shall  automatically  be reduced to the  maximum  rate  permitted  by
applicable  law and  Lender  shall  promptly  refund to  Borrower  any  interest
received by Lender in excess of the maximum  lawful rate or, if so  requested by
Borrower,  shall apply such excess to the principal  balance of the Obligations.
It is the intent  hereof that  Borrower  not pay or  contract  to pay,  and that
Lender not receive or contract to receive,  directly or indirectly in any manner
whatsoever,  interest  in excess of that  which  may be paid by  Borrower  under
applicable law.


                                        6





                  2.3.  Prepayment.  Borrower may prepay amounts outstanding 
under the Line of Credit at any time without premium or penalty.

         3.  SECURITY INTEREST.

                  3.1. Grant of Security  Interest.  As security for the payment
of the Note and all Obligations  whatsoever of Borrower to Lender,  Borrower and
each  Subsidiary  hereby  grant to Lender a  continuing,  general  lien upon and
security interest in and to the following described property,  wherever located,
whether  now  existing  or  hereafter  acquired  or  arising,  namely:  (a)  the
Collateral and (b) all proceeds of the Collateral.

                  3.2. Grant of Security Interest by Subsidiaries.  The grant of
security  interests  in and to the  Collateral  by each  Subsidiary  pursuant to
Section 3.1 shall be  unconditional  and  absolute  and,  without  limiting  the
generality  of the  foregoing,  shall not be released,  discharged  or otherwise
affected by:

                  (a) any extension, renewal, settlement,  compromise, waiver or
release in respect of any obligation of Borrower under this Agreement, the Note,

transactions,  provided  that nothing  herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

                  (f) any invalidity or unenforceability  relating to or against
Borrower, or any other Subsidiary, for any reason related to this Agreement, any
other Loan Document, or any provision of applicable law or regulation purporting
to prohibit the payment by Borrower, of the principal of or interest on the Note
or any other amount payable by Borrower under this  Agreement,  the Note, or any
other Loan Document; or

                                        7





                  (g) any other act or  omission  to act or delay of any kind by
Borrower,  any  other  Subsidiary,  Lender  or any  other  Person  or any  other
circumstance  whatsoever  which might, but for the provisions of this paragraph,
constitute  a legal  or  equitable  discharge  of any  Subsidiary's  obligations
hereunder.

Regulation X of the Board of Governors of the Federal  Reserve  System),  order,
writ, judgment,  injunction,  decree, determination or award presently in effect
having  applicability  to  Borrower  or any  Subsidiary  or  any  organizational
document of Borrower or any Subsidiary, or result in a breach of or constitute a
default under any indenture or loan or credit  agreement or any other agreement,
lease or instrument to which  Borrower or any  Subsidiary is a party or by which
it or its  properties  may be bound or  affected;  and neither  Borrower nor any
Subsidiary  is in default under any such law,  rule,  regulation,  order,  writ,
judgment,  injunction,  decree,  determination  or award or any such  indenture,
agreement, lease or instrument.

         6. AFFIRMATIVE  COVENANTS.  Borrower  covenants to Lender that from and
after the date hereof,  and so long as any amounts  remain  unpaid on account of
any of the  Obligations or this Agreement  remains  effective  (whichever is the
last to occur),  Borrower will comply (and will cause each Subsidiary to comply)
with the affirmative covenants set forth below:

                  6.1.  Records Respecting Collateral.  All records of Borrower
and its Subsidiaries with respect to the Collateral will be kept, in the case of
Borrower, at the Executive

                                                        10





Office or, in the case of a Subsidiary, at the location shown on Exhibit "A" and
will not be removed  from such  address  without  the prior  written  consent of
Lender.

                  6.2.  Further  Assurances.  Borrower shall duly execute and/or
deliver  (or  cause  to  be  duly  executed  and/or  delivered)  to  Lender  any
instrument,  invoice,  document,  document of title, order, financing statement,
assignment,  waiver,  consent or other writing which may be reasonably necessary
to Lender to carry out the  terms of this  Agreement  and any of the other  Loan
Documents and to perfect its security  interest in and facilitate the collection
of the  Collateral,  the proceeds  thereof,  and any other  property at any time
constituting security to Lender. Borrower shall perform or cause to be performed
such acts as Lender may reasonably  request to establish and maintain for Lender
a valid and perfected  security  interest in and secure title to the Collateral,
free and clear of any  liens,  encumbrances  or  security  interests  other than
Permitted Encumbrances.

                  6.3.  Right to  Inspect.  Lender  (or any  person  or  persons
designated by it) shall, in its sole  discretion,  have the right to call at any
place of business of Borrower or any Subsidiary at any reasonable  time,  during
normal  business  hours  following   reasonable   advance  notice  and,  without
hindrance, disruption or delay, inspect, audit, check and make extracts from any
books,  records,  journals,  orders,  receipts,  correspondence or other data of
Borrower or any Subsidiary of Borrower relating to the Collateral, to Borrower's
business or to any other transactions between the parties hereto.

                  6.4. Reports.  Borrower shall, as soon as practicable,  but in
any event on or before  twenty (20) days after the end of each  calendar  month,
furnish or cause to be furnished to Lender a status report,  certified by a duly
authorized officer of Borrower,  showing the aggregate dollar value of the items
comprising the Collateral and the age of each  individual item thereof as of the
last day of the preceding  fiscal month  (segregating  such items in such manner
and to such degree as Lender may reasonably request). In any event, upon request
from Lender, made at any time hereafter,  subject to Borrower's  confidentiality
constraints,  Borrower shall furnish  Lender with a then current  Account Debtor
address list.

                  6.5.  Payment of Taxes.  Borrower  shall pay and discharge and
shall cause each  Subsidiary  to pay and discharge  all taxes,  assessments  and
governmental  charges upon Borrower or such  Subsidiary,  their income and their
properties  prior to the date on which penalties  attach thereto,  unless and to
the extent only that (x) such taxes,  assessments and  governmental  charges are
being contested in good faith and by appropriate proceedings by Borrower or such
Subsidiary, (y) Borrower or such Subsidiary maintains reasonable reserves on its
books  therefor and (z) the payment of such taxes does not result in a Lien upon
any of the Collateral other than a Permitted Encumbrance.

                  6.6.  Certificate of No Default.  Borrower shall, on a 
quarterly basis not later than forty-five (45) days after the close of each of 
its first three Fiscal Quarters and not later than ninety (90) days after the 
close of its Fiscal Year, certify to Lender, in a statement executed by a

                                       11





duly authorized  Officer of Borrower in the form of Exhibit "E" attached hereto,
that no Event of Default and no Default Condition exists or has occurred, or, if
an Event of Default  or  Default  Condition  exists,  specifying  the nature and
period of existence thereof.

                  6.7.  Change of Principal  Place of Business.  Borrower hereby
agrees that if, at any time hereafter, Borrower elects to (i) move the Executive
Office or the principal place of business of a Subsidiary,  (ii) change its name
or the name of a Subsidiary, or (iii) change its organizational structure or the
organizational  structure of any Subsidiary to a structure  other than a limited
liability  company or  corporation,  Borrower  will notify  Lender in writing at
least thirty (30) days prior thereto.

                  6.8.  Preservation  of Existence.  Borrower shall preserve and
maintain  and shall cause each  Subsidiary  to maintain its  existence,  rights,
franchises and privileges in the jurisdiction of its  organization,  and qualify
and  remain  qualified  to do  business  in  each  jurisdiction  in  which  such
qualification  is necessary or desirable in view of its business and  operations
or the ownership of its properties.

                  6.9.  Compliance  With Laws.  Borrower  shall comply and shall
cause each Subsidiary to comply with the  requirements  of all applicable  laws,
rules, regulations and orders of any governmental authority,  noncompliance with
which would or could  materially  adversely  affect their  respective  financial
condition or the ownership,  maintenance or operation of any material portion of
any of their  respective  properties.  Without  limiting the foregoing,  each of
Borrower and its  Subsidiaries  shall obtain and maintain all material  permits,
licenses and other authorizations which are required under, and otherwise comply
with, all federal, state, and local laws and regulations.

                  6.10. Certain Required Notices.  Promptly, upon its receipt of
notice or knowledge  thereof,  Borrower will report to Lender:  (i) any lawsuit,
proceeding, action, arbitration, claim or governmental investigation, inquiry or
proceeding,  pending or threatened  against  Borrower or any Subsidiary  seeking
damages for an amount in excess of $1 million;  or (ii) the existence and nature
of any Default Condition or Event of Default.

         7. NEGATIVE COVENANTS. Borrower covenants to Lender that from and after
the date  hereof and so long as any amount  remains  unpaid on account of any of
the Obligations or this Agreement  remains  effective  (whichever is the last to
occur), Borrower will not do (and will not permit any Subsidiary to do), without
the prior written consent of Lender, any of the things or acts set forth below:

                  7.1.  Encumbrances.  Create, assume, or suffer to exist any 
Lien on the Collateral except for Permitted Encumbrances and as permitted by 
Section 4.3 of this Agreement.

                  7.2.  Business Locations.  Transfer the Executive Office or 
the principal place of business of any Subsidiary to, or maintain records with
respect to, Collateral at any locations

                                       12





other than those at which the same are presently kept or maintained as set forth
on Exhibit "A"  hereto,  except  upon at least  thirty  (30) days prior  written
notice to Lender and after the  delivery to Lender of financing  statements,  if
reasonably  required by Lender,  in form reasonably  satisfactory to Lender,  to
perfect or continue the perfection of Lender's Lien.

         8.  EVENTS OF DEFAULT.  The occurrence of any events or conditions set
forth below shall constitute an Event of Default hereunder, provided that any 
requirement for the giving of notice or the lapse of time, or both, has been 
satisfied:

                  8.1. Notes.  Borrower shall fail to repay the principal on the
Note on the Maturity Date or at such earlier time as may be provided pursuant to
this  Agreement or make  payments of interest  within five  Business Days of the
giving  of  written  notice  by Lender to  Borrower  of  Lender's  right to such
payment.

                  8.2.  Other  Obligations.  Borrower  shall  fail to  make  any
payments  (other than those  described  in Section  8.1) on its  Obligations  to
Lender  within 10 days of the giving of written  notice by Lender to Borrower of
Lender's right to such payment.

                  8.3.    Misrepresentations.    Borrower    shall    make   any
representation or warranty in any of the Loan Documents or in any certificate or
statement  furnished at any time hereunder or in connection with any of the Loan
Documents which proves to have been untrue or misleading in any material respect
when made or furnished.

                  8.4.  Covenants.  Borrower  shall default in the observance or
performance of any covenant or agreement (other than payment obligations covered
by Section 8.1 or 8.2 above)  contained in any of the Loan Documents unless such
default is cured to  Lender's  satisfaction  within  thirty  (30) days after the
sooner to occur of receipt of notice of such  default from Lender or the date on
which such default first becomes known to Borrower.

                  8.5.  Other Debts.  Borrower shall default in connection with 
any agreement for indebtedness for borrowed money of $10,000,000 or more with 
any creditor other than Lender which entitles said creditor to accelerate the 
maturity thereof.

                  8.6.  Voluntary  Bankruptcy.  Borrower  shall file a voluntary
petition in bankruptcy or a voluntary  petition or answer  seeking  liquidation,
reorganization,  arrangement, readjustment of its debts, or for any other relief
under  the  Bankruptcy  Code,  or  under  any  other  act or law  pertaining  to
insolvency  or  debtor  relief,  whether  state,  Federal,  or  foreign,  now or
hereafter  existing;  Borrower  shall enter into any  agreement  indicating  its
consent to,  approval of, or  acquiescence  in, any such petition or proceeding;
Borrower shall apply for or permit the appointment by consent or acquiescence of
a receiver,  custodian or trustee of Borrower for all or a  substantial  part of
its property; Borrower shall make an assignment for the benefit of creditors; or
Borrower shall be unable or shall fail to pay its debts  generally as such debts
become due, or

                                       13





Borrower  shall  admit,  in writing,  its  inability or failure to pay its debts
generally as such debts become due.

                  8.7.  Involuntary  Bankruptcy.  There  shall  have been  filed
against Borrower an involuntary  petition in bankruptcy or seeking  liquidation,
reorganization,  arrangement,  readjustment of its debts or for any other relief
under  the  Bankruptcy  Code,  or  under  any  other  act or law  pertaining  to
insolvency or debtor relief, whether state, federal or foreign, now or hereafter
existing;  Borrower  shall  suffer or permit the  involuntary  appointment  of a
receiver,  custodian or trustee of Borrower or for all or a substantial  part of
its  property;  or Borrower  shall suffer or permit the issuance of a warrant of
attachment,  execution or similar process against all or any substantial part of
the property of Borrower;  provided,  however,  that no filing,  appointment  or
issuance  described  above shall  constitute an Event of Default if such filing,
appointment  or issuance is dismissed or  terminated  within ninety (90) days of
its occurrence.

                  8.8.  Judgments.  A final judgment or order for the payment of
money is rendered against Borrower or any Subsidiary in the amount of $5,000,000
or more  (exclusive of amounts  covered by insurance) and either (x) enforcement
proceedings  shall have been  commenced  by any creditor  upon such  judgment or
order,  or (y) a stay of enforcement  of such judgment or order,  by reason of a
pending appeal or otherwise, shall not be in effect for any period of sixty (60)
consecutive days.

                  8.9. Bankruptcy of Affiliate.  Any motion,  complaint or other
pleading  is filed in any  bankruptcy  case of any  person or entity  other than
Borrower  and such  motion,  complaint or pleading  seeks the  consolidation  of
Borrower's assets and liabilities with the assets and liabilities of such person
or entity;  provided,  however, that the filing of any such motion, complaint or
pleading shall not  constitute an Event of Default if such motion,  complaint or
pleading is dismissed within ninety (90) days of its filing.

                  8.10.  Material Adverse Change.  There shall occur any 
material adverse change in the financial condition, operations or business 
prospects of Borrower.

         9. REMEDIES.  Upon the occurrence of any Default  Condition or Event of
Default,  Lender's obligation to disburse amounts under the Line of Credit shall
immediately cease; provided,  however, that if such obligation has ceased due to
the  occurrence  of a Default  Condition,  and such Default  Condition  does not
become an Event of Default due to its having been cured or waived  before it has
matured into an Event of Default, then such obligation shall be reinstated as of
the date such  Default  Condition  is cured or waived.  Upon the  occurrence  or
existence of any Event of Default, or at any time thereafter,  without prejudice
to the rights of Lender to enforce its claims  against  Borrower for damages for
failure by Borrower to fulfill any of its obligations hereunder, subject only to
prior receipt by Lender of payment in full of all Obligations  then  outstanding
in immediately available funds, Lender shall have all of the rights and remedies
set forth below, and it may exercise any one, more, or all of such remedies,  in
its sole discretion, without thereby waiving any of the others.

                                       14






                  9.1.  Acceleration of the Obligations.  Lender, at its option,
may declare all of the Obligations to be immediately due and payable,  whereupon
the same shall become immediately due and payable without  presentment,  demand,
protest,  notice of  nonpayment  or any other  notice  required by law  relative
thereto,  all of  which  are  hereby  expressly  waived  by  Borrower,  anything
contained herein to the contrary  notwithstanding and, in connection  therewith,
if Lender so elects, by further written notice to Borrower,  Lender may increase
the rate of interest charged on the Note then outstanding for so long thereafter
as Lender  further  shall  elect to an amount  not to exceed the  Default  Rate.
Failure to declare  all  Obligations  due shall not  constitute  an  election by
Lender to waive its right to demand  payment  at any time and in any  event,  as
Lender  in its  discretion  may deem  appropriate.  Thereafter,  Lender,  at its
option,  may, but shall not be obligated  to, accept less than the entire amount
of Obligations due, if tendered,  provided,  however, that unless then agreed to
in writing by Lender,  no such acceptance shall or shall be deemed to constitute
a waiver of any Event of Default or a reinstatement of any commitments of Lender
hereunder.

                  9.2. Remedies of a Secured Party.  Lender shall thereupon have
the rights and  remedies of a secured  party under the UCC in effect on the date
thereof  (regardless  of whether the same has been  enacted in the  jurisdiction
where the rights or remedies are asserted),  including,  without limitation, the
right to take  possession of any of the Collateral or the proceeds  thereof,  to
sell or otherwise  dispose of the same,  and to apply the proceeds  therefrom to
any of the  Obligations  in such order as Lender,  in its sole  discretion,  may
elect.  Lender shall give Borrower  written  notice of the time and place of any
public  sale of the  Collateral  or the time  after  which  any  other  intended
disposition  thereof is to be made. The requirement of sending reasonable notice
shall be met if such  notice is given to  Borrower at least ten (10) days before
such  disposition.   Expenses  of  retaking,   holding,  insuring,   preserving,
protecting,  preparing  for sale or  selling  or the like  with  respect  to the
Collateral  shall include,  in any event,  reasonable  attorneys' fees and other
legally  recoverable   collection  expenses,   all  of  which  shall  constitute
Obligations.

                  9.3.  Repossession  of the  Collateral.  Lender  may  take the
Collateral or any portion  thereof into its  possession,  by such means (without
breach of the peace) and through  agents or otherwise  as it may elect (and,  in
connection therewith, demand that Borrower assemble the Collateral at a place or
places  and in such  manner  as Lender  shall  prescribe),  and  sell,  lease or
otherwise dispose of the Collateral or any portion thereof in its then condition
or following  any  commercially  reasonable  preparation  or  processing,  which
disposition may be by public or private  proceedings,  by one or more contracts,
as a unit or in parcels,  at any time and place and on any terms, so long as the
same are  commercially  reasonable  and Borrower  hereby waives all rights which
Borrower  has or may have  under and by virtue of  O.C.G.A.  sections  44-14-260
through  44-14-264,  including,  without  limitation,  the right of  Borrower to
notice and to a judicial hearing prior to seizure of any Collateral by Lender.

                  9.4.  Other Remedies.  Unless and except to the extent 
expressly provided for to the contrary herein, the rights of Lender specified 
herein shall be in addition to, and not in

                                       15





limitation of,  Lender's  rights under the UCC, as amended from time to time, or
any other statute or rule of law or equity,  or under any other provision of any
of  the  Loan  Documents,   all  of  which  may  be  exercised  successively  or
concurrently.


         10.  MISCELLANEOUS.

                  10.1.  Waiver.  Each and every right  granted to Lender  under
this  Agreement,  or any of the other  Loan  Documents,  or any  other  document
delivered hereunder or in connection herewith or allowed it by law or in equity,
shall be  cumulative  and may be exercised  from time to time. No failure on the
part of Lender to exercise, and no delay in exercising,  any right shall operate
as a waiver thereof,  nor shall any single or partial  exercise by Lender of any
right preclude any other or future exercise thereof or the exercise of any other
right.  No waiver by Lender of any Default  Condition or Event of Default  shall
constitute a waiver of any subsequent Default Condition or Event of Default.

                  10.2.  GOVERNING LAW.  THIS AGREEMENT AND THE OTHER
LOAN DOCUMENTS, AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER AND THEREUNDER, SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
GEORGIA.

                  10.3. Survival. All representations,  warranties and covenants
made herein and in the Loan  Documents  shall survive the execution and delivery
hereof and thereof but shall terminate when Lender's obligation to advance funds
under the Line of Credit has expired. The terms and provisions of this Agreement
shall continue in full force and effect, notwithstanding the payment of the Note
or the termination of the Line of Credit, until all of the Obligations have been
paid in full and Lender's  obligation  to advance funds under the Line of Credit
has expired.

                  10.4. Assignment. No assignment hereof or of any Loan Document
shall be made by Borrower  without the prior written  consent of Lender.  Lender
may collaterally assign, pledge or transfer its rights under this Agreement, the
Note or any other Loan Document to Lender's  senior lenders  without the consent
of Borrower;  any other  assignment or transfer  shall require the prior written
consent of Borrower,  which consent shall not be  unreasonably  withheld.  It is
understood  and agreed by the parties hereto that Lender's  rights,  but not its
obligations,  under this Agreement,  the Note and all other Loan Documents shall
be  collaterally  assigned by Lender to [Money Center Bank],  in its capacity as
administrative agent under the Magellan Facility, for the benefit of the lenders
under the Magellan  Facility,  pursuant to a written  instrument  of  assignment
satisfactory  to  [Money  Center  Bank]  and  the  parties  hereto;  and  Lender
acknowledges  and agrees that such  collateral  assignment of rights shall in no
way relieve  Lender of any of Lender's  obligations  under this Agreement or the
Loan Documents.


                                                        16





                  10.5.  Counterparts.  This Agreement may be executed in two or
more counterparts, each of which when fully executed shall be an original, and 
all of said counterparts taken together shall be deemed to constitute one and 
the same agreement.

                  10.6.  Reimbursement.  Borrower  shall pay to Lender on demand
all  reasonable  out-of-pocket  costs and expenses  that Lender pays or actually
incurs  in  connection   with  the   negotiation,   preparation,   consummation,
enforcement  and  termination  of this  Agreement and the other Loan  Documents.
Borrower will pay all expenses  incurred by it in the transaction.  In the event
Borrower becomes a debtor under the Bankruptcy  Code,  Lender's secured claim in
such case shall  include  interest on the  Obligations  and all fees,  costs and
charges  provided  for  herein  (including,   without   limitation,   reasonable
attorneys'  fees actually  incurred) all to the extent allowed by the Bankruptcy
Code. All expenses due under this Section 10.6 shall be Obligations.

                  10.7.  Successors and Assigns.  This Agreement and Loan 
Documents shall be binding upon and inure to the benefit of the successors and 
permitted assigns of the parties hereto and thereto.

                  10.8.  Severability.  If any provision of this Agreement or of
any of the Loan  Documents or the  application  thereof to any party  thereto or
circumstances  shall be invalid or unenforceable to any extent, the remainder of
such Loan Documents and the  application  of such  provisions to any other party
thereto or circumstance  shall not be affected  thereby and shall be enforced to
the greatest extent permitted by law.

                  10.9.  Notices.  All notices,  requests and demands to or upon
the  respective  parties  hereto shall be deemed to have been given or made when
personally delivered, upon the date originally received if delivered by telecopy
transmission followed by registered or certified mail confirmation, one Business
Day following deposit with an overnight delivery service, or three Business Days
following  deposit in the mail,  registered or certified  mail,  postage prepaid

with the remaining Loan Documents,  constitute the entire agreement  between the
