         (c)      No Consent.  The execution,  delivery and  performance of this
                  Agreement and the other Loan Documents,  and the  consummation
                  of the transactions  contemplated  hereby and thereby,  do not
                  (i) conflict  with,  result in a violation of, or constitute a
                  default  under (A) any  provision  of  Borrower's  articles or
                  certificate  of   incorporation   or  bylaws,   (B)  any  law,
                  governmental  regulation,  court decree or order applicable to
                  Borrower,  or (C) any other  document  or  agreement  to which
                  Borrower is a party, or (ii) require the consent,  approval or
                  authorization of any third party.

         (d)      Financial  Condition.  Each  financial  statement  of Borrower
                  supplied to  Schlinger  is true,  correct and  complete in all
                  material  respects and fairly  presents  Borrower's  financial
                  condition in all material respects as of the date of each such
                  statement.  There has been no material  adverse change in such
                  financial  condition  or results  of  operations  of  Borrower
                  subsequent to the date of the most recent financial  statement
                  supplied to Schlinger.

         (e)      Litigation.  There  are  no  actions,  suits  or  proceedings,
                  pending or, to the knowledge of Borrower,  threatened  against
                  or affecting  Borrower or the  properties of Borrower,  before
                  any court or  governmental  department,  commission  or board,
                  which,  if  determined  adversely  to  Borrower,  would have a
                  material adverse effect on the business,  financial condition,
                  properties, operations or prospects of Borrower.

         (f)      Taxes.  Governmental Charges.  Borrower has filed all federal,
                  state and local tax reports and returns required by any law or
                  regulation  to be filed  by it and has  either  duly  paid all
                  taxes,  duties and charges  indicated due on the basis of such
                  returns  and  reports,  or  made  adequate  provision  for the
                  payment thereof,  and the assessment of any material amount of
                  additional  taxes in excess of those paid and  reported is not
                  reasonably  expected.  There  is no tax  Lien  notice  against
                  Borrower or its properties presently on file.

         (g)      ERISA  Compliance.   Borrower  is  in  compliance  with  ERISA
                  concerning  Borrower's  ERISA Plan, if any, or is not required
                  to  contribute  to any  "multi-employer  plan" as  defined  in
                  Section 401 of ERISA.

         (h)      Compliance  with Laws.  Borrower is conducting its business in
                  material  compliance  with all  statutes,  rules,  regulations
                  and/or  ordinances  imposed  by  any  governmental  unit  upon
                  Borrower  or upon  its  businesses,  operations  and  property
                  (including,   without  limitation,  all  Environmental  Laws).
                  Borrower  has  all  permits  and  licenses  necessary  for the
                  operations  of its  business  as  presently  conducted  and as
                  proposed to be conducted.

         (i)      Tradenames.  Borrower and Guarantors conduct business under no
                  trade or assumed name except KINT conducts  business under the
                  tradename Bird Promotions.

                  statement  furnished by any Obligor, or by any other person on
                  behalf of any Obligor, to Schlinger is not true and correct in
                  any material respect.

                  Guarantor is limited or  terminated  by operation of law or by
                  such Guarantor,  or any such Guarantor  becomes the subject of
                  an insolvency proceeding.

         (o)      Judgment. The entry against any of the Obligors of a final and
                  nonappealable  judgment  for the payment of money in excess of
                  $25,000 (not covered by insurance satisfactory to Schlinger in
                  Schlinger's sole discretion).

         Nothing  contained in this Loan  Agreement  shall be construed to limit
         the events of default enumerated in any of the other Loan Documents and
         all such events of default shall be cumulative.

13.      Remedies.  Upon  the  occurrence  of any one or  more of the  foregoing
         Events of Default,  the entire unpaid balance of principal of the Note,
         together with all accrued but unpaid  interest  thereon,  and all other
         indebtedness  owing to Schlinger by Borrower at such time shall, at the
         option of Schlinger, become immediately due and payable without further
         notice, demand,  presentation,  notice of dishonor, notice of intent to
         accelerate, notice of acceleration, protest or notice of protest of any
         kind, all of which are expressly waived by Borrower; provided, however,
         concurrently  and  automatically  with  the  occurrence  of an Event of
         Default under  Subsections  12 (g) or 12 (h) of this Agreement the Note
         and all other  indebtedness owing to Schlinger by Borrower at such time
         shall,  without any action by  Schlinger,  become  immediately  due and
         payable,  without  further  notice,  demand,  presentation,  notice  of
         dishonor,  notice of  acceleration,  notice  of  intent to  accelerate,
         protest or notice of protest  of any kind,  all of which are  expressly
         waived by Borrower.  All rights and remedies of Schlinger  set forth in
         this  Agreement and in any of the other Loan  Documents are  cumulative
         and may also be exercised by  Schlinger,  at its option and in its sole
         discretion, upon the occurrence of an Event of Default.

14.      Indemnification.   Borrower  hereby  indemnifies  and  agrees  to  hold
         harmless  and defend all  Indemnified  Persons from and against any and
         all  Indemnified  Claims.  THE  FOREGOING  INDEMNIFICATION  SHALL APPLY
         WHETHER OR NOT SUCH INDEMNIFIED  CLAIMS ARE IN ANY WAY OR TO ANY EXTENT
         OWED,  IN  WHOLE OR IN PART,  UNDER  ANY  CLAIM  OR  THEORY  OF  STRICT
         LIABILITY,  OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR
         OMISSION  OF ANY  INDEMNIFIED  PERSON,  but  shall  exclude  any of the
         foregoing resulting from such Indemnified  Person's gross negligence or
         willful  misconduct.  If Borrower  or any third party ever  alleges any
         gross negligence or willful  misconduct by any Indemnified  Person, the
         indemnification  provided for in this Section shall nonetheless be paid
         upon demand,  subject to later adjustment or reimbursement,  until such
         time as a court of competent jurisdiction enters a final judgment as to
         the  extent  and  affect of the  alleged  gross  negligence  or willful
         misconduct.  Upon  notification and demand,  Borrower agrees to provide
         defense of any  Indemnified  Claim and to pay all costs and expenses of
         counsel  selected by any  Indemnified  Person in respect  thereof.  Any
         Indemnified  Person against whom any Indemnified  Claim may be asserted
         reserves the right to settle or compromise any such  Indemnified  Claim
         as such Indemnified  Person may determine in its sole  discretion,  and
         the obligations of such  Indemnified  Person,  if any,  pursuant to any
         such  settlement  or  compromise  shall be deemed  included  within the
         Indemnified  Claims.  Except as specifically  provided in this Section,
         Borrower waives all notices from any Indemnified Person. The provisions
         of this Section shall survive the termination of this Agreement.

15.      Rights  Cumulative.  All  rights of  Schlinger  under the terms of this
         Agreement  shall be  cumulative  of, and in addition  to, the rights of
         Schlinger  under  any and all other  agreements  between  Borrower  and
         Schlinger  (including,  but not limited to, the other Loan  Documents),
         and not in  substitution  or  diminution of any rights now or hereafter
         held by Schlinger under the terms of any other agreement.

16.      Waiver and Agreement.  Neither the failure nor any delay on the part of
         Schlinger to exercise any right, power or privilege herein or under any
         of the other Loan  Documents  shall  operate as a waiver  thereof,  nor
         shall any single or partial exercise of such right,  power or privilege
         preclude any other or further  exercise  thereof or the exercise of any
         other right,  power or  privilege.  No waiver of any  provision in this
         Loan  Agreement or in any of the other Loan  Documents and no departure
         by Borrower  therefrom  shall be effective  unless the same shall be in
         writing and signed by  Schlinger,  and then shall be effective  only in
         the specific instance as specified in such writing.  No modification or
         amendment to this Loan  Agreement or to any of the other Loan Documents
         shall be valid or  effective  unless  the same is  signed  by the party
         against whom it is sought to be enforced.

17.      Benefits. This Agreement shall be binding upon and inure to the benefit
         of Schlinger and Borrower, and their respective successors and assigns;
         provided,  however,  that  Borrower may not,  without the prior written
         consent of Schlinger,  assign any rights, powers, duties or obligations
         under this Agreement or any of the other Loan Documents.

18.      Notices.  All  notices,   requests,  demands  or  other  communications
         required or permitted to be given pursuant to this  Agreement  shall be
         in writing and given by (i) personal delivery,  (ii) expedited delivery
         service with proof of  delivery,  (iii)  United  States  mail,  postage
         prepaid,  registered or certified mail,  return receipt  requested,  or
         (iv) telecopy (with receipt  thereof  confirmed by telecopier)  sent to
         the intended  addressee at the address set forth on the signature  page
         hereof and shall be deemed to have been received either, in the case of
         personal delivery,  as of the time of personal delivery, in the case of
         expedited delivery service,  as of the date of first attempted delivery
         at the address and in the manner provided herein,  in the case of mail,
         upon deposit in a depository  receptacle  under the care and custody of
         the United  States  Postal  Service,  or in the case of telecopy,  upon
         receipt.  Either  party  shall have the right to change its address for
         notice  hereunder to any other location within the  continental  United
         States by notice to the other party of such new address at least thirty
         (30) days prior to the effective date of such new address.

19.      Governing Law; Venue;  Submission to  Jurisdiction.  THIS AGREEMENT AND
         THE  OTHER  LOAN  DOCUMENTS  SHALL  BE  GOVERNED  BY AND  CONSTRUED  IN
         ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO
         THE  PRINCIPLES  OF  CONFLICTS  OF LAWS  THEREOF,  EXCEPT TO THE EXTENT
         PERFECTION  AND THE  EFFECT  OF  PERFECTION  OR  NON-PERFECTION  OF THE
         SECURITY  INTEREST GRANTED  HEREUNDER OR THEREUNDER,  IN RESPECT OF ANY
         PARTICULAR COLLATERAL, ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER
         THAN THE STATE OF TEXAS.  THIS  AGREEMENT AND THE OTHER LOAN  DOCUMENTS
         ARE  PERFORMABLE BY THE PARTIES IN DALLAS COUNTY,  TEXAS.  BORROWER AND
         SCHLINGER EACH AGREE THAT DALLAS COUNTY,  TEXAS, SHALL BE THE EXCLUSIVE
         VENUE FOR  LITIGATION OF ANY DISPUTE OR CLAIM ARISING UNDER OR RELATING
         TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AND THAT SUCH COUNTY IS
         A  CONVENIENT  FORUM IN WHICH TO  DECIDE  ANY SUCH  DISPUTE  OR  CLAIM.
         BORROWER AND SCHLINGER EACH CONSENT TO THE PERSONAL JURISDICTION OF THE
         STATE  AND  FEDERAL  COURTS  LOCATED  IN DALLAS  COUNTY,  TEXAS FOR THE
         LITIGATION OF ANY SUCH DISPUTE OR CLAIM.  BORROWER  IRREVOCABLY WAIVES,
         TO THE FULLEST EXTENT  PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
         OR  HEREAFTER  HAVE TO THE  LAYING OF THE VENUE OF ANY SUCH  PROCEEDING
         BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING  BROUGHT
         IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

                                       13

20.      Waiver of Jury Trial.  BORROWER AND SCHLINGER  EACH HEREBY  IRREVOCABLY
         WAIVES,  TO THE MAXIMUM EXTENT  PERMITTED BY LAW, ANY RIGHT IT MAY HAVE
         TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION  DIRECTLY OR INDIRECTLY
         AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION  WITH THIS AGREEMENT
         OR ANY TRANSACTION CONTEMPLATED HEREBY OR ASSOCIATED HEREWITH.

21.      Invalid  Provisions.  If any provision of this  Agreement or any of the
         other Loan  Documents is held to be illegal,  invalid or  unenforceable
         under present or future laws,  such provision  shall be fully severable
         and the remaining provisions of this Agreement or any of the other Loan
         Documents  shall  remain  in full  force  and  effect  and shall not be
         affected by the illegal,  invalid or unenforceable  provision or by its
         severance.

22.      Expenses. Borrower shall pay all costs and expenses (including, without
         limitation,  reasonable  attorneys'  fees) in  connection  with (i) the
         preparation  of the Loan  Documents,  (ii) any action  required  in the
         course of administration of the indebtedness and obligations  evidenced
         by the Loan  Documents,  and (iii) any  action  in the  enforcement  of
         Schlinger's rights upon the occurrence of Event of Default.

23.      Participation  of the Loan.  Provided  that the  prospective  purchaser
         and/or assignee is not a business competitor of Borrower, as determined
         by  Schlinger  in  its  reasonable  discretion,  Borrower  agrees  that
         Schlinger may, at its option, sell interests in the Loan and its rights
         under this  Agreement and the other Loan  Documents  and, in connection
         with each such sale,  Schlinger  may disclose any  financial  and other
         information   available  to  Schlinger   concerning  Borrower  to  each
         prospective purchaser and assignee.

24.      Maximum Interest Rate.

                                       14

<PAGE>

         (a)      No interest rate specified in this Agreement or any other Loan
                  Document  shall at any time exceed the Maximum Rate. If at any
                  time the interest rate (the  "Contract  Rate") for the Loan or
                  any other  indebtedness,  liability or obligation shall exceed
                  the  Maximum  Rate,  thereby  causing  the  interest  accruing
                  thereon to be limited to the Maximum Rate, then any subsequent
                  reduction in the Contract Rate  therefor  shall not reduce the
                  rate of interest  therefor  below the  Maximum  Rate until the
                  aggregate  amount  of  interest  accrued  thereon  equals  the
                  aggregate  amount of interest which would have accrued thereon
                  if the Contract Rate had at all times been in effect.

         (b)      Notwithstanding  anything to the  contrary  contained  in this
                  Agreement or the other Loan  Documents,  none of the terms and
                  provisions of this Agreement or the other Loan Documents shall
                  ever be  construed to create a contract or  obligation  to pay
                  interest  at a  rate  in  excess  of  the  Maximum  Rate;  and
                  Schlinger shall never charge, receive, take, collect,  reserve
                  or apply,  as interest on the Loan or any other  indebtedness,
                  liability or  obligation,  any amount in excess of the Maximum
                  Rate. The parties hereto agree that any interest, charge, fee,
                  expense or other obligation  provided for in this Agreement or
                  in the other Loan Documents which  constitutes  interest under
                  applicable  law  shall  be,  ipso  facto and under any and all
                  circumstances,  limited or  reduced to an amount  equal to the
                  lesser  of (i) the  amount  of  such  interest,  charge,  fee,
                  expense  or other  obligation  that  would be  payable  in the
                  absence of this  Section  24(b) or (ii) an amount,  which when
                  added to all other  interest  payable under this Agreement and
                  the  other  Loan  Documents,  equals  the  Maximum  Rate.  If,
                  notwithstanding  the foregoing,  Schlinger ever contracts for,
                  charges,  receives,  takes,  collects,  reserves or applies as
                  interest any amount in excess of the Maximum Rate, such amount
                  which  would be deemed  excessive  interest  shall be deemed a
                  partial  payment or prepayment of principal of the Loan or any
                  other  indebtedness,   liability  or  obligation  and  treated
                  hereunder as such; and if the Loan or any other  indebtedness,
                  liability or obligation,  or applicable portions thereof,  are
                  paid in full,  any remaining  excess shall promptly be paid to
                  the  Borrower  or other  applicable  Obligor or  Obligors  (as
                  appropriate).  In  determining  whether the  interest  paid or
                  payable,  under any specific contingency,  exceeds the Maximum
                  Rate, the Borrower and the other Obligors and Schlinger shall,
                  to  the  maximum  extent  permitted  by  applicable  law,  (a)
                  characterize  any nonprincipal  payment as an expense,  fee or
                  premium  rather  than  as  interest,   (b)  exclude  voluntary
                  prepayments  and  the  effects  thereof,   and  (c)  amortize,
                  prorate,  allocate  and spread in equal or  unequal  parts the
                  total amount of interest  throughout  the entire  contemplated
                  term  of the  Loan or any  other  indebtedness,  liability  or
                  obligation,  or  applicable  portions  thereof,  so  that  the
                  interest  rate does not  exceed the  Maximum  Rate at any time
                  during  the  term  of  the  Loan  or any  other  indebtedness,
                  liability  or   obligation;   provided  that,  if  the  unpaid
                  principal  balance is paid and  performed in full prior to the
                  end of the full contemplated term thereof, and if the interest
                  received for the actual  period of existence  thereof  exceeds
                  the Maximum  Rate,  Schlinger  shall refund to the Borrower or
                  other  applicable  Obligor or Obligors  (as  appropriate)  the
                  amount of such excess and, in such event,  Schlinger shall not
                  be  subject  to  any  penalties   provided  by  any  laws  for
                  contracting  for,  charging,  receiving,  taking,  collecting,
                  reserving or applying interest in excess of the Maximum Rate.

25.      Conflicts.  In the event any term or provision  hereof is  inconsistent
         with or  conflicts  with  any  term  or  provision  in any of the  Loan
         Documents,  the terms and provisions  contained in this Agreement shall
         be controlling.

26.      Counterparts.  This Agreement may be separately  executed in any number
         of counterparts,  each of which shall be an original, but all of which,
         taken  together,  shall  be  deemed  to  constitute  one and  the  same
         instrument.  Delivery of an executed  counterpart  of this Agreement by
         telecopy  shall be  equally  as  effective  as  delivery  of a manually
         executed  counterpart  of  this  Agreement.  Any  party  delivering  an
         executed counterpart of this Agreement by telecopy also shall deliver a
         manually  executed  counterpart  of this  Agreement  but the failure to
         deliver a manually executed  counterpart shall not affect the validity,
         enforceability, and binding effect of this Agreement.

27.      Amendment and Restatement of the Original Loan Agreement.  Effective as
         of the date hereof,  this Agreement  shall  constitute an amendment and
         restatement of all, but not an extinguishment,  discharge, satisfaction
         or novation of any,  indebtedness  liabilities  and/or  obligations  of
         Borrower under the Original Loan Agreement.

28.      ENTIRE AGREEMENT. THIS AGREEMENT, THE NOTE AND THE OTHER LOAN DOCUMENTS
         REPRESENT THE FINAL  AGREEMENT  BETWEEN THE PARTIES HERETO WITH RESPECT
         TO THE TRANSACTIONS  CONTEMPLATED HEREIN AND MAY NOT BE CONTRADICTED BY
         EVIDENCE OF PRIOR,  CONTEMPORANEOUS,  OR SUBSEQUENT  ORAL AGREEMENTS OF
