                                            more  days in any month  during  the
                                            Term,  the average  daily balance of

                                            month  shall  bear  interest  at the

                                            any excess  amount  shall  either be
                                            applied,  at Lender's option, to the
                                            outstanding  Loans in such  order as

                                            force of law) of any such authority,
                                            central bank or  comparable  agency,
                                            has or  would  have  the  effect  of
                                            reducing   the  rate  of  return  on
                                            Lender's capital as a consequence of
                                            its obligations hereunder to a level
                                            below that which  Lender  could have
                                            achieved  but  for  such   adoption,
                                            change or  compliance  (taking  into
                                            consideration Lender's policies with
                                            respect to capital  adequacy)  by an
                                            amount   deemed   by  Lender  to  be
                                            material,  then,  from time to time,
                                            Borrower  shall  pay upon  demand to
                                            Lender  such  additional  amount  or
                                            amounts  as will  compensate  Lender
                                            for such  reduction.  In determining
                                            such amount or  amounts,  Lender may
                                            use  any  reasonable   averaging  or
                                            attribution  methods. The protection
                                            of this  Section  shall be available
                                            to Lender regardless of any possible
                                            contention    of    invalidity    or
                                            inapplicability  with respect to the
                                            applicable   law,    regulation   or

                           effect during such month on the average daily balance
                           during such month of any amounts payable by Lender to
                           Borrower hereunder which are not drawn by Borrower on
                           the Settlement Date.

                           6.      Security Interest.

                           (a) Pursuant to the Original  Agreement,  Greka, Saba
and Santa Maria hereby  ratify and  reaffirm the security  interest of Lender in
the  Collateral  as created and  perfected  pursuant to the  Original  Agreement
("Prior  Security  Interests").  Greka,  Saba and Santa Maria hereby confirm and
agree that the UCC-1 financing  statements  executed and delivered in connection
with the  Original  Agreement  remain in full force and effect and  continue  to
perfect the Prior Security  Interest and the security  interests created hereby.
All security  interests  created hereby shall be in addition and supplemental to
that  created  as  aforesaid  and  shall  relate  back to the date of the  Prior
Security Interests.

                           (b)  In  extension   of  and  without   limiting  the
provisions of Section 6(a) above,  to secure the prompt payment to Lender of the
Obligations,  Borrower hereby assigns, pledges and grants to Lender a continuing
security  interest  in and to the  Collateral,  whether now owned or existing or
hereafter  acquired or arising and wheresoever  located (whether or not the same
is subject to Article 9 of the Uniform  Commercial  Code). All of the Borrower's
ledger sheets, files, records,  books of account,  business papers and documents
relating to the Collateral  shall,  until delivered to or removed by Lender,  be
kept by Borrower  in trust for Lender  until all  Obligations  have been paid in
full.  Each  confirmatory  assignment  schedule  or  other  form  of  assignment
hereafter  executed by Borrower shall be deemed to include the foregoing  grant,
whether or not the same appears therein.

                           (c) Lender may file one or more financing  statements
disclosing  Lender's  security  interest in the  Collateral  without  Borrower's
signature  appearing thereon or Lender may sign on Borrower's behalf as provided
in Section 13 hereof.  The parties  agree that a carbon,  photographic  or other
reproduction of this Agreement shall be sufficient as a financing statement.  If
any Receivable  becomes  evidenced by a promissory note or any other  instrument
for the payment of money,  Borrower will immediately  deliver such instrument to
Lender appropriately endorsed.

                           7.   Representations   Concerning   the   Collateral.
Borrower  represents  and  warrants  (each of  which  such  representations  and
warranties  shall be  deemed  repeated  upon the  making of each  request  for a
Revolving  Credit  Advance  and made as of the time of each and every  Revolving
Credit Advance hereunder):

                           (a) all the  Collateral (i) is owned by Borrower free
and clear of all claims, liens,  security interests and encumbrances  (including
without  limitation  any claims of  infringement)  except (A) those in  Lender's
favor  and  (B)  Permitted  Liens  and  (ii)  is not  subject  to any  agreement
prohibiting  the  granting  of a security  interest  or  requiring  notice of or
consent to the granting of a security interest;

                           (b) all Receivables (i) represent  complete bona fide
transactions  which require no further act under any circumstances on Borrower's
part to  make  such  Receivables  payable  by  Customers,  (ii)  to the  best of
Borrower's  knowledge,  are not  subject to any  present,  future or  contingent
Disputes;  (iii)  do not  represent  bill  and hold  sales,  consignment  sales,

definition  of Eligible  Receivables,  except as may  otherwise be  specifically
disclosed  in  such  Borrowing  Base  Certificate  or as  otherwise  theretofore
disclosed in writing to Lender; and (v) Borrower has no knowledge of any fact or
circumstance not disclosed to Lender in the pertinent Borrowing Base Certificate
or otherwise in writing,  which would impair the validity or  collectibility  of
any  Receivable  and that all documents in connection  with each  Receivable are
genuine.

                           (c) in the event any  amounts  due and owing from any
account  debtor to Borrower on any Eligible  Receivable  shall become subject to
any  Dispute,  or to any  other  adjustment  otherwise  permitted  to be made in
accordance  with the  terms and  provisions  hereof  in the  ordinary  course of
business and prior to the occurrence of an Event of Default hereunder,  Borrower
agrees that it shall,  at the time of the  submission of the next Borrowing Base
Certificate required to be delivered to Lender immediately following the date on
which Borrower  learns  thereof,  provide Lender with notice  thereof.  Borrower
further  agrees  that it shall also  notify  Lender  promptly of all returns and
credits  in  respect  of  any  Receivables  included  within  a  Borrowing  Base
Certificate, which notice shall specify the Receivables affected.

                           8. Covenants  Concerning the  Collateral.  During the
Term, Borrower covenants that it shall:

                           (a) not dispose of any of the  Collateral  whether by
sale,  lease or  otherwise  except for (i) the sale of Inventory in the ordinary
course of business, and (ii) the disposition or transfer of obsolete and wornout
Equipment in the ordinary  course of business during any fiscal year of Borrower

extent  that (x) the  proceeds  of any  such  disposition  are  used to  acquire
replacement  Equipment  which is subject to  Lender's  first  priority  security
interest or (y) the proceeds of which are remitted to Lender in reduction of the
Obligations;

<PAGE>


                           (b) not encumber,  mortgage,  pledge, assign or grant
any security  interest in any  Collateral or any of  Borrower's  other assets to
anyone other than Lender except as set forth on Schedule  1(C)  attached  hereto
and made a part hereof;

                           (c) place notations upon Borrower's  books of account
and any financial  statement  prepared by Borrower to disclose Lender's security
interest in the Collateral;

                           (d)  defend  the  Collateral  against  the claims and
demands of all parties.

                           (e)  keep  and  maintain  the   Collateral   in  good
operating  condition,  except  for  ordinary  wear and tear,  and shall make all
necessary  repairs  and  replacements  thereof  so that the value and  operating
efficiency  shall at all times be maintained and  preserved.  Borrower shall not
permit any such items to become a fixture to real estate or  accessions to other
personal property;

                           (f) not extend the  payment  terms of any  Receivable
without prompt notice thereof to Lender;

                           (g) perform all other  steps  requested  by Lender to
create and maintain in Lender's favor a valid perfected first security  interest
in all Collateral; and

                           (h) promptly provide Lender with duplicate  originals
of all credits which  Borrower  issues to its Customers and  immediately  notify
Lender of any  merchandise  returns  or  Disputes.  Borrower  shall  settle  all
Disputes  at no cost or  expense  to Lender.  Should  Lender so elect,  upon the
occurrence of any Event of Default, Lender may at any time in its discretion (i)
withdraw Borrower's authority to issue credits to its Customers without Lender's
prior  written  consent;  (ii)  litigate  Disputes or settle them  directly with
Customers on terms  acceptable to Lender;  or (iii) direct Borrower to set aside
and identify as Lender's  property any returned or  repossessed  merchandise  or
other goods which by sale resulted in Receivables theretofore assigned to Lender
("Retained  Goods").  All Retained Goods (and the proceeds thereof) shall be (A)
held by  Borrower  in trust for  Lender as  Lender's  property,  (B)  subject to
Lender's  security  interest  hereunder,  and (C) disposed of only in accordance
with Lender's express written instructions.

                           9.  Collection  and  Maintenance  of  Collateral  and
Records. Lender may at any time verify Borrower's Receivables utilizing an audit
control  company or any other agent of Lender.  Lender or Lender's  designee may
notify Customers, at any time at Lender's sole discretion,  of Lender's security
interest in Receivables,  collect them directly and charge the collection  costs
and  expenses to  Borrower's  account,  but,  unless and until Lender does so or
gives Borrower other instructions,  Borrower shall instruct all of its Customers
to make payments on account of Receivables to an account under Lender's dominion
and  control at such bank as Lender may  designate,  as provided by the terms of
Section  23.  To the  extent  Borrower  receives  any  payments  on  account  of
Receivables,  it shall  hold such  payments  for  Lender's  benefit  in trust as
Lender's  trustee and immediately  deliver them to Lender in their original form
with all necessary endorsements or, as directed by Lender, deposit such payments
as  directed  by Lender  pursuant  to  Section  22 hereof.  Lender  will  credit
(conditional upon final  collection) all such payments to Borrower's  account on
the Settlement Date.  Promptly after the creation of any  Receivables,  Borrower
shall  provide  Lender with  schedules  describing  all  Receivables  created or
acquired  by  Borrower  and  shall  execute  and  deliver  confirmatory  written
assignments of such Receivables to Lender, but Borrower's failure to execute and
deliver such schedules or written  confirmatory  assignments of such Receivables
shall not affect or limit Lender's  security  interest or other rights in and to
the  Receivables.  Borrower  shall  furnish,  at  Lender's  request,  copies  of
contracts,  invoices or the equivalent,  and any original  shipping and delivery
receipts for all merchandise sold or services  rendered and such other documents
and information as Lender may require. All of Borrower's invoices shall bear the
terms stated on the applicable  customer order,  and no change from the original
terms of such customer order shall be made without the prior written  consent of
Lender.  Borrower shall provide Lender on a monthly  (within ten (10) days after
the end of each month),  or more  frequent  basis,  as  requested  by Lender,  a
summary report of Borrower's current  Inventory,  certified as true and accurate
by Borrower's  President or Chief  Financial  Officer,  as well as an aged trial
balance of Borrower's existing accounts payable.  Borrower shall provide Lender,
as requested  by Lender,  such other  schedules,  documents  and/or  information
regarding the Collateral as Lender may require.  Without limiting the foregoing,
Borrower shall provide to Lender a borrowing base certificate upon Santa Maria's
invoicing of customers,  but no less  frequently  than weekly  ("Borrowing  Base
Certificate"),  which  must be in form and  substance  acceptable  to Lender and
which  Borrowing  Base  Certificate  shall certify to Lender,  and shall contain
sufficient  information  and  calculations  as  Lender  may  deem  necessary  or
desirable,   in  order  to  verify  any  Receivables   Availability,   Inventory
Availability,  the  applicable  Formula  Amount and  whether or not  Receivables
and/or  Inventory  included  therein are Eligible  Receivables  and/or  Eligible
Inventory.  Without limiting the foregoing, a Borrowing Base Certificate must be
executed  and  delivered  by  Borrower to Lender at the time of or prior to each
request for Revolving Credit Advances pursuant to Section 4. Each such Borrowing
Base Certificate shall be delivered to Lender at its office described in Section
26 below, on each relevant Business Day.

                           10.  Inspections.  During normal business hours, and,
so long as no Event of Default or Incipient Event of Default shall have occurred
hereunder,  upon  thirty-six  (36) hours prior notice to Borrower,  Lender shall
have  the  right  to  (a)  visit  and  inspect  Borrower's  properties  and  the
Collateral,  (b) inspect, audit and make extracts from Borrower's relevant books
and  records,  including,  but not limited to,  management  letters  prepared by
independent accountants, and (c) discuss with Borrower's principal officers, and
independent accountants,  Borrower's business,  assets,  liabilities,  financial
condition,  results of operations and business prospects.  Borrower will deliver
to Lender any instrument necessary for Lender to obtain records from any service
bureau maintaining records for Borrower.

                           11.  Financial  Information.  Borrower  shall provide
Lender (a) as soon as available,  but in any event within ninety (90) days after
the end of each of Borrower's fiscal years,  Borrower's  balance sheet as at the
end of such fiscal year and the related statements of income,  retained earnings
and statement of cash flow for such fiscal year,  setting  forth in  comparative
form the figures as at the end of and for the previous fiscal year,  which shall
have been reported on by independent  certified public  accountants who shall be
satisfactory  to Lender and shall be accompanied by an unqualified  audit report
issued  by  such  independent  certified  public  accountants;  (b) as  soon  as
available,  drafts  of  Borrower's  balance  sheet  as at  the  end of  each  of
Borrower's fiscal years and the related statements of income,  retained earnings
and  statement  of cash flow for such fiscal  year,  which have been  internally
prepared by Borrower;  (c) as soon as available,  but in any event within thirty
(30) days after the close of each month and quarter, the balance sheet as at the
end of such month and  quarter and the related  statements  of income,  retained
earnings and changes in statement of cash flow for such month and quarter, which
have been internally  prepared by Borrower.  All financial  statements  required
under (a), (b) and (c) above shall be prepared in accordance with GAAP,  subject
to year  end  adjustments  in the  case of  monthly  and  quarterly  statements.
Together with the financial statements furnished pursuant to (a) above, Borrower
shall deliver a certificate of Borrower's certified public accountants addressed
to Lender  stating that (i) they have caused this  Agreement  and the  Ancillary
Agreements to be reviewed and (ii) in making the  examination  necessary for the
issuance of such financial  statements,  nothing has come to their  attention to
lead them to believe  that any Event of Default  or  Incipient  Event of Default
exists and, in  particular,  they have no  knowledge  of any Event of Default or
Incipient Event of Default or, if such is not the case, specifying such Event of
Default or  Incipient  Event of Default  and its nature,  when it  occurred  and
whether it is  continuing.  At the times the financial  statements are furnished
pursuant to (a), (b) and (c) above,  a certificate  of  Borrower's  President or
Chief Financial  Officer shall be delivered to Lender stating that,  based on an
examination sufficient to enable him to make an informed statement,  no Event of
Default  or  Incipient  Event of  Default  exists,  or, if such is not the case,
specifying  such Event of Default or Incipient  Event of Default and its nature,
when it occurred, whether it is continuing and the steps being taken by Borrower
with respect to such event. If any internally  prepared  financial  information,
including that required under this section,  is  unsatisfactory in any manner to
Lender,  Lender  may  request  that  Borrower's   independent  certified  public
accountants review same.

                           In addition to the  foregoing  financial  statements,
Borrower shall furnish Lender no less than thirty (30)

days prior to the  beginning  of each  fiscal year  commencing  with fiscal year
2000, a month by month projected  operating budget and cash flow for such fiscal
year (including an income statement for each month and a balance sheet as at the
end  of  the  last  month  in  each  fiscal  quarter),  such  projections  to be
accompanied by a certificate  signed by Borrower's  President or Chief Financial
Officer to the effect that such  projections  have been prepared on the basis of
sound  financial  planning  practice  consistent with past budgets and financial
statements and that such officer has no reason to question the reasonableness of
any material assumptions on which such projections were prepared.

                           12.   Additional   Representations,   Warranties  and
Covenants.  Borrower represents and warrants (each of which such representations
and  warranties  shall be deemed  repeated  upon the  making of a request  for a
Revolving  Credit  Advance  and  made as of the  time of each  Revolving  Credit
Advance made hereunder), and covenants that:

                           (a) Saba and Santa Maria is each a  corporation  duly
organized and validly  existing  under the laws of the State of  California  and
Greka is a corporation duly organized and validly existing under the laws of the
State of Colorado and each  Borrower is duly  qualified  and in good standing in
every other state or  jurisdiction  in which the nature of  Borrower's  business
requires such qualification except where the failure to qualify would not have a
material adverse effect on the Borrower's business.;

                           (b) the execution,  delivery and  performance of this
Agreement and the Ancillary  Agreements (i) have been duly authorized,  (ii) are
not in contravention of Borrower's  certificate of incorporation,  by-laws or of
any indenture, agreement or undertaking to which Borrower is a party or by which
Borrower is bound and (iii) are within Borrower's corporate powers;

                           (c)  this  Agreement  and  the  Ancillary  Agreements
executed  and  delivered  by Borrower are  Borrower's  legal,  valid and binding
obligations, enforceable in accordance with their terms;

                           (d) it  keeps  and will  continue  to keep all of its
books and records  concerning  the  Collateral at Borrower's  executive  offices
located at the address set forth in the introductory paragraph of this Agreement
and will not move such books and records  without  giving Lender at least thirty
(30) days prior written notice;

                           (e) (1) the operation of Borrower's  business and the
Collateral is and will  continue to be in  compliance  in all material  respects
with all applicable federal,  state and local laws, including but not limited to
all applicable environmental laws and regulations and Sanction/Embargo Programs.

                                  (2) Borrower has  established  and  maintained
and will  continue  to  maintain  a  system  to  assure  and  monitor  continued
compliance  with  all  applicable   environmental  laws,  and   Sanction/Embargo
Programs, which system shall include periodic reviews of such compliance.

                                  (3) in the event the Borrower  obtains,  gives
or receives notice of any release or threat of release of a reportable  quantity
of any Hazardous  Substances  on its property (any such event being  hereinafter
referred to as a "Hazardous  Discharge")  or receives  any notice of  violation,
request for information or notification  that it is potentially  responsible for
investigation  or cleanup of  environmental  conditions on its property,  demand
letter or complaint, order, citation, or other written notice with regard to any
Hazardous  Discharge  or  violation  of any  environmental  laws  affecting  its
property or  Borrower's  interest  therein (any of the  foregoing is referred to
herein as an "Environmental Complaint") from any Person or entity, including any
state agency  responsible in whole or in part for  environmental  matters in the
state in which such  property  is located  or the  United  States  Environmental
Protection Agency (any such person or entity hereinafter the "Authority"),  then
the Borrower  shall,  within five (5) Business Days, give written notice of same
to the Lender  detailing facts and  circumstances of which the Borrower is aware
giving  rise  to  the  Hazardous   Discharge  or  Environmental   Complaint  and
periodically  inform Lender of the status of the matter.  Such information is to
be  provided  to allow the  Lender  to  protect  its  security  interest  in the
Collateral and is not intended to create nor shall it create any obligation upon
the Lender with respect thereto.

                                  (4)  Borrower  shall  respond  promptly to any
Hazardous Discharge or Environmental  Complaint and take all necessary action in
order  to  safeguard  the  health  of any  Person  and to avoid  subjecting  the
Collateral to any lien, charge, claim or encumbrance.  If Borrower shall fail to
respond  promptly to any  Hazardous  Discharge  or  Environmental  Complaint  or
Borrower shall fail to comply with any of the requirements of any  environmental
laws,  the Lender may, but without the obligation to do so, for the sole purpose
of protecting the Lender's interest in Collateral:  (A) give such notices or (B)
enter onto  Borrower's  property (or authorize  third parties to enter onto such
property) and take such actions as the Lender (or such third parties as directed
by the Lender) deem  reasonably  necessary or  advisable,  to clean up,  remove,
mitigate or otherwise  deal with any such Hazardous  Discharge or  Environmental
Complaint. All reasonable costs and expenses directly incurred by the Lender (or
such third parties) in the exercise of any such rights,  including any sums paid
in connection with any judicial or administrative  investigation or proceedings,
fines and  penalties,  together with interest  thereon from the date expended at
the Default Rate for Revolving  Credit Advances shall be paid upon demand by the
Borrower,  and until paid shall be added to and become a part of the Obligations
secured  by the  liens  created  by the  terms of this  Agreement  or any  other
agreement between Lender and Borrower.

                                  (5) Borrower  shall defend and  indemnify  the
Lender and hold the Lender harmless from and against all loss, liability, damage
and expense,  claims,  costs,  fines and penalties,  including  attorney's fees,
directly  suffered  or  incurred  by the  Lender  under or on  account of A. any
environmental laws,  including,  without  limitation,  the assertion of any lien
thereunder,  with  respect  to any  Hazardous  Discharge,  the  presence  of any
Hazardous  Substances  affecting  Borrower's  property,  whether or not the same
originates or emerges from  Borrower's  property or any contiguous  real estate,
including  any loss of  value of the  Collateral  as a result  of the  foregoing
except to the extent such loss, liability, damage and expense is attributable to
any Hazardous Discharge resulting from actions on the part of the Lender, and B.
any Sanction/Embargo  Program. The Borrower's obligations under Section 12(e)(v)
A. shall arise upon the discovery of the presence of any Hazardous Substances on
the  Borrower's  property,   whether  or  not  any  federal,   state,  or  local
environmental  agency has taken or threatened any action in connection  with the
presence of any Hazardous Substances, and under Section 12(e)(v) B on failure to
comply with any  Sanction/Embargo  Program.  The  Borrower's  obligation and the
indemnifications hereunder shall survive the termination of this Agreement.

                                  (6)  For   purposes   of  Section   12(e)  all
references to Borrower's  property  shall be deemed to include all of Borrower's
right, title and interest in and to all owned and/or leased premises;

                           (f)  based  upon  the  Employee   Retirement   Income
Security Act of 1974  ("ERISA"),  as amended,  and the regulations and published
interpretations  thereunder:  (i)  Borrower  has not  engaged in any  Prohibited
Transactions as defined in Section 406 of ERISA and Section 4975 of the Internal
Revenue  Code of 1986,  as amended,  and the rules and  regulations  promulgated
thereunder;  (ii) Borrower has met all applicable  minimum funding  requirements
under Section 302 of ERISA in respect of its plans,  if any;  (iii) Borrower has
no knowledge of any event or  occurrence  which would cause the Pension  Benefit
Guaranty  Corporation  to  institute  proceedings  under  Title  IV of  ERISA to
terminate  any  employee  benefit  plan(s);   (iv)  Borrower  has  no  fiduciary
responsibility for investments with respect to any plan existing for the benefit
of persons other than Borrower's employees;  and (v) Borrower has not withdrawn,
completely  or  partially,  from any  multiemployer  pension plan so as to incur
liability under the Multiemployer Pension Plan Amendments Act of 1980;

financial condition as reflected in such statements since the date thereof,  and

amount in excess of $3,000,000 in the aggregate  during  Borrower's  2000 fiscal

                           (p) Borrower shall  maintain a fixed charge  coverage
ratio  (calculated by dividing the sum of dividends,  scheduled debt  repayment,
interest payments  (including cash interest payments to Greka Energy Corporation
and/or Saba Petroleum  Company and excluding  accrued  interest payable to Greka
Energy Corporation and/or Saba Petroleum  Company),  cash portion of taxes paid,
and cash capital  expenditures into EBITDA, all as calculated in accordance with
GAAP) of no less than 1.3:1.  For  purposes  of this  Section  12(p),  the fixed
charge coverage ratio shall be measured at December 31, 1999 for the immediately
preceding nine (9) months and at March 31, 2000 and for each June 30,  September
30,  December 31 and March 31 thereafter for the  immediately  preceding  twelve
(12) month period;

                           (q) it shall  cause to be  maintained  at all times a
ratio of Total  Liabilities to Tangible Net Worth plus  Subordinated Debt of not
greater  than the ratio of:  1.5 to 1 as of  Borrower's  fiscal  quarter  ending
December 31, 1999 and continuously thereafter;

                           (r) the  outstanding  balance  of the Term Loan shall
not at any time  exceed  75% of the then  current PV 10 value of the Oil and Gas
Properties  owned by  Borrower.  Provided no other Event of Default or Incipient
Event  of  Default  shall  have  occurred  hereunder  and  Borrower  remains  in
compliance  with all  other  financial  covenants  set  forth  herein,  upon the
occurrence  of a violation  of this  covenant,  Borrower  shall be  permitted an
opportunity  to cure such  violation  within 60 days following the occurrence of
any such violation, provided, however, that such cure will not be permitted more
than two (2) times during the Term and not more than once during any consecutive
12 month period.

                           (s) none of the proceeds of the Loans  hereunder will
be used directly or indirectly  to  "purchase" or "carry"  "margin  stock" or to
repay  indebtedness  incurred to "purchase" or "carry" "margin stock" within the
respective  meanings of each of the quoted terms under Regulation G of the Board
of  Governors  of the  Federal  Reserve  System  as now  and  from  time to time
hereafter in effect;

                           (t) it will  bear the full risk of loss from any loss
of any nature  whatsoever  with respect to the  Collateral.  At its own cost and
expense in amounts and with carriers acceptable to Lender, it shall (i) keep all
its insurable  properties  and  properties  in which it has an interest  insured
against the hazards of fire, flood,  sprinkler leakage, those hazards covered by
extended coverage insurance and such other hazards,  and for such amounts, as is
customary in the case of companies  engaged in businesses  similar to Borrower's
including, without limitation,  business interruption insurance; (ii) maintain a
bond in such  amounts  as is  customary  in the  case of  companies  engaged  in
businesses similar to Borrower's insuring against larceny, embezzlement or other
criminal  misappropriation  of insured's  officers and  employees who may either
singly or jointly  with others at any time have access to the assets or funds of
Borrower  either  directly  or through  authority  to draw upon such funds or to
direct  generally the  disposition  of such assets;  (iii)  maintain  public and
product  liability  insurance  against  claims  for  personal  injury,  death or
property damage suffered by others; (iv) maintain all such workers' compensation
or  similar  insurance  as may be  required  under  the  laws  of any  state  or
jurisdiction  in which Borrower is engaged in business;  (v) furnish Lender with
(x) copies of all policies and evidence of the  maintenance  of such policies at
least thirty (30) days before any  expiration  date,  and (y)  appropriate  loss
payable endorsements in form and substance satisfactory to Lender, naming Lender
as loss payee and providing  that as to Lender the insurance  coverage shall not
be impaired  or  invalidated  by any act or neglect of Borrower  and the insurer
will provide Lender with at least thirty (30) days notice prior to cancellation.
Borrower  shall  instruct the  insurance  carriers that in the event of any loss
thereunder,  the carriers  shall make payment for such loss to Lender and not to
Borrower and Lender jointly. If any insurance losses are paid by check, draft or
other  instrument  payable to Borrower  and Lender  jointly,  Lender may endorse
Borrower's name thereon and do such other things as Lender may deem advisable to
reduce the same to cash.  Lender is hereby  authorized to adjust and  compromise
claims.  All loss  recoveries  received by Lender upon any such insurance may be
applied to the Obligations, in such order as Lender in its sole discretion shall
determine.  Notwithstanding  the  foregoing,  to the extent  that any  insurance
proceeds received by Lender do not belong to Borrower or result from the loss of
property of Borrower which is not  Collateral,  Lender will return such proceeds
to Borrower.  Any surplus  shall be paid by Lender to Borrower or applied as may
be otherwise  required by law. Any deficiency  thereon shall be paid by Borrower
to Lender, on demand; and

                           (u) it shall not purchase or acquire  obligations  or
stock of, or any other interest in, or make any investment in any entity, except
(A)  obligations  issued or  guaranteed  by the United  States of America or any
agency thereof,  (B) commercial  paper with maturities of not more than 180 days
and a published  rating of not less than A-1 or P-1 (or the equivalent  rating),
(C) certificates of time deposit and bankers'  acceptances  having maturities of
not more  than 180  days and  repurchase  agreements  backed  by  United  States
government  securities  of a  commercial  bank if (x) such  bank has a  combined
capital and surplus of at least  $500,000,000,  or (y) its debt obligations,  or
those of a holding company of which it is a subsidiary,  are rated not less than
A (or the  equivalent  rating)  by a  nationally  recognized  investment  rating
agency,  (D) U.S. money market funds that invest solely in obligations issued or
guaranteed  by the  United  States  of  America  or an Agency  thereof,  and (E)
Eurodollar time deposits with financial  institutions with a published rating of
not less than A-1 or P-1 (or the equivalent rating).

                           (v) (1) Borrower and its  Subsidiaries  have reviewed
the effect that the Year 2000 Issue would have on their  respective  businesses.
The costs to Borrower  and its  Subsidiaries  of any  reprogramming  required to
avoid the Year 2000 Issue to permit the proper functioning of Borrower's and its
Subsidiaries'  computer  software,  hardware and firmware  systems and equipment
containing  embedded  microchips  and the  proper  processing  of data,  and the
testing of such reprogramming, and of the reasonably foreseeable consequences of
the Year 2000 Issue to Borrower and its  Subsidiaries  (including  reprogramming
errors and the failure of systems or equipment  supplied by others or with which
Borrower's and its Subsidiaries'  computer systems interface) are not reasonably
expected to result in an Event of Default or to have a material  adverse  effect
on Borrower's or its Subsidiaries' businesses, assets, operations,  prospects or
condition (financial or otherwise).

                                  (2)  Borrower has  evaluated  and assessed the
potential  impact of the Year 2000 Issue upon  Borrower's and its  Subsidiaries'
customers,  key  suppliers  and  vendors  and their  efforts to manage the risks
arising out of the Year 2000 Issue,  and Borrower has determined that Borrower's
and its Subsidiaries' businesses,  assets,  operations,  prospects and condition
(financial and otherwise) shall not be materially adversely affected by any such
impact or risks.

                                  (3) Borrower  shall take, and shall cause each
of its  Subsidiaries  to take, all necessary  action to complete in all material
respects, the reprogramming of computer software,  hardware and firmware systems
and  equipment  containing  embedded  microchips  owned  or  operated  by or for
Borrower  and its  Subsidiaries  or used or relied  upon in the conduct of their
businesses  (including  systems and  equipment  supplied by others or with which
such  systems  of  Borrower  or any of its  Subsidiaries  interface)  reasonably
necessary to avoid the Year 2000 Issue to permit the proper  functioning of such
computer systems and other equipment and the proper  processing of data, and the
testing of such systems and  equipment,  as so  reprogrammed.  At the request of
Lender,  Borrower shall  provide,  and shall cause each of its  Subsidiaries  to
provide,  to Lender  reasonable  assurance of its compliance  with the preceding
sentence.

                           (w) Borrower  will cause  Randeep S. Grewal to remain
active in the management of Borrower as the Chairman,  Chief Executive  Officer,
President  and  director  of  Borrower  for a period  of at least  two (2) years
following the Closing Date.

                           (x) In the  event  that any  Borrower  shall  sell or
dispose of any real property or in the event Borrower shall sell any subsidiary,
all  proceeds of such sale shall first be applied to repay  amounts  outstanding
under the Term Loan.  Such  payments  will be  applied by Lender in the  inverse
order of maturity.

                           (y)  Borrower  will  use the  proceeds  of  Revolving
Credit Advances only for its proper working capital purposes.  Borrower will use
the  proceeds of the Term Loan only for the  purchase of the Santa Maria Oil and
Gas  Properties,  the  Vintage Oil and Gas  Properties  and the  refinancing  of
Borrower's existing indebtedness to Lender.

                           (z) Santa Maria shall not  transfer any of its assets
to any other Borrower.

                           (aa)  Upon the  occurrence  of any  Event of  Default
hereunder, Borrower shall immediately cease any and all payments to Greka Energy
Corporation.  Until the  occurrence  of any Event of Default  Borrower  may make
distributions of funds to Greka Energy Corporation in the ordinary course of its
business.

                           (bb) Borrower  shall at all times  maintain a minimum
Tangible Net Worth of at least $26,000,000.

                           (cc) Additional  Warranties.  Santa Maria  covenants,
represents and warrants that:

                                  (1) Interests in Property.  Santa Maria is and
will continue to be the lawful owner of the property more particularly described
on Schedule  12(cc)  annexed  hereto ( the Property") and the interests of Santa
Maria in the  Property,  as set  forth in  Schedule12(cc)  hereto,  are true and
correct  as of the  date  hereof  and  shall  not  change  so long as any of the
Obligations remain outstanding.

                                  (2)  Leases  in  Effect.  All  of  the  Leases
specifically  described in Schedule  12(cc)  hereof (the  "Leases")  are in full
force and effect, and all covenants,  express or implied, in respect thereof, or
of any  assignment  thereof  which may affect the validity of any of the Leases,
have been performed.

                                  (3)  Gas  Contracts.  Santa  Maria  (i) is not
obligated in any  material  respect by virtue of any  prepayment  made under any
contract  containing  a  "take-or-pay"  or  "prepayment"  provision or under any
similar agreement to deliver  hydrocarbons  produced from or allocated to any of
the Property at some future date without  receiving full payment therefor at the
time of delivery, and (ii) has not produced gas, in any material amount, subject
to, and  neither  Santa Maria nor any of the  Property is subject to,  balancing
rights of third  parties or balancing  duties under  governmental  requirements,
except  as to such  matters  for which  Santa  Maria  has  established  monetary
reserves  adequate in amount to satisfy such obligations and has segregated such
reserves from other accounts.

                                  (4) Refunds. No orders of, proceedings pending
before,  or other  governmental  requirements of, the Federal Energy  Regulatory
Commission,   or  any  other  similar  state  or  federal   regulatory  body  or
governmental authority exist which could result in Santa Maria being required to
refund any material portion of the proceeds  received or to be received from the
sale of hydrocarbons constituting part of the Property.

                                  (5)  Maintenance  of Leases.  Santa Maria will
keep and continue all Leases,  estates and  interests  herein  described and all
contracts and agreements relating thereto in full force and effect in accordance
with the terms thereof and will not permit the same to lapse or otherwise become
impaired for failure to comply with the obligations thereof,  whether express or
implied.  In this  connection,  Santa  Maria shall not release any of the Leases
without the prior written consent of Lender.

                                  (6)  Operation of Property.  Santa Maria shall
operate or, to the extent that the right of operation is vested in others,  will
exercise  its best  efforts to require the  operator to operate the Property and
all  wells  drilled   thereon  and  that  may  hereafter  be  drilled   thereon,
continuously and in good workmanlike manner in accordance with the best usage of
the field and in  accordance  with all laws of the United  States of America and
the state in which the Property is situated,  as well as all rules,  regulations
and laws of any governmental  agency having  jurisdiction to regulate the manner
in which the operation of the Property shall be carried on, and will comply with
all terms and  conditions  of the  Leases  it now holds and each  assignment  or
contract  obligating  Santa Maria in any way with respect to the  Property;  but
nothing  herein shall be construed to empower  Santa Maria to bind the Lender to
any contract or obligation or render the Lender in any way responsible or liable
for bills or obligations incurred by Santa Maria.


                                      -33-

                                  (7) Transfer or Division Orders.  Upon request
of Lender,  Santa Maria will execute and deliver  written notices of assignments
to any persons,  corporations or other entities owing or which may in the future
owe to Santa Maria monies or accounts  arising in  connection  with (a) any oil,
gas or mineral  production from all or any portion of the Property;  (b) any gas
contracts,  processing  contracts  or  other  contracts  relating  to all or any
portion of the Property;  or (c) the operation of or production  from all or any
portion of the  Property.  The  notices of  assignments  shall  advise the third
parties that all of the monies or accounts described above have been assigned to
Lender,  and if  required by Lender,  shall also  require and direct that future
payments  thereof,  including amounts then owing and unpaid, be paid directly to
Lender.

                                  (8) Uneconomic Wells. Should proceeds from the
sale of  production  from  any oil  and/or  gas  well  constituting  part of the
Property (net of production,  severance and windfall profit taxes and royalties,
overriding  royalties and other payments out of or measured by  production)  not
exceed the expense of  operation  of such well  (including,  but not limited to,
operator's  overhead,  payments to  contractors  and  suppliers and annual taxes
assessed on the basis of the value of the property  prorated on a monthly basis,
but expressly  excluding  any portion of the cost of drilling or completing  the
relevant well or the cost of non-routine  workover or remedial  operators) for a
period in excess of three  consecutive  calendar  months,  then, upon receipt by
Santa Maria of written  notification from Lender,  Santa Maria will (a) take all
necessary  steps to abandon the relevant well, or (b) provide from sources other
than proceeds from the sale of production  attributable  to the Property  (i.e.,
through borrowings or contractual commitments obtained from third parties not in
violation of any provision of this Deed of Trust) the funds  required to pay the
share of Santa Maria of the expenses associated with the continuing operation of
such well.

                                  13.   Power  of  Attorney.   Borrower   hereby
appoints  Lender or any other  Person whom Lender may  designate  as  Borrower's
attorney,  with power to: (i)  endorse  Borrower's  name on any  checks,  notes,
acceptances, money orders, drafts or other forms of payment or security that may
come into Lender's possession;  (ii) sign Borrower's name on any invoice or bill
of lading relating to any Receivables,  drafts against Customers,  schedules and
assignments  of  Receivables,  notices of assignment,  financing  statements and
other public records, verifications of account and notices to or from Customers;

by mail, telephone,  telegraph or otherwise with Customers; (iv) execute customs
declarations  and such other  documents  as may be required  to clear  Inventory
through Customs;  (v) do all things  necessary to carry out this Agreement,  any
Ancillary  Agreement  and  all  related  documents;  and  (vi) on or  after  the
occurrence  and  continuation  of an Event of  Default,  notify the post  office
authorities to change the address for delivery of Borrower's  mail to an address
designated by Lender, and to receive,  open and dispose of all mail addressed to
Borrower.  Borrower  hereby  ratifies  and  approves  all acts of the  attorney.
Neither  Lender nor the attorney will be liable for any acts or omissions or for
any error of judgment or mistake of fact or law. This power,  being coupled with
an  interest,  is  irrevocable  so long as any  Receivable  which is assigned to
Lender or in which Lender has a security  interest  remains unpaid and until the
Obligations have been fully satisfied.

                                  14.  Expenses.   Borrower  shall  pay  all  of
Lender's   out-of-pocket  costs  and  expenses,   including  without  limitation
reasonable fees and  disbursements of counsel retained or employed by Lender and
appraisers,  in connection with the preparation,  execution and delivery of this
Agreement and the Ancillary  Agreements,  and in connection with the prosecution
or defense of any action,  contest,  dispute,  suit or proceeding concerning any
matter in any way arising out of, related to or connected with this Agreement or
any Ancillary Agreement.  Borrower shall also pay all of Lender's  out-of-pocket
costs  and  expenses,   including   without   limitation   reasonable  fees  and
disbursements of counsel retained or employed by Lender,  in connection with (a)
the preparation,  execution and delivery of any waiver, any amendment thereto or
consent proposed or executed in connection with the transactions contemplated by
this Agreement or the Ancillary  Agreements,  (b) Lender's obtaining performance
of the Obligations under this Agreement and any Ancillary Agreements, including,
but not limited to, the enforcement or defense of Lender's  security  interests,
assignments of rights and liens hereunder as valid perfected security interests,
(c) any  attempt to  inspect,  verify,  protect,  collect,  sell,  liquidate  or
otherwise  dispose of any Collateral,  and (d) any  consultations  in connection
with any of the foregoing.  Borrower shall also pay Lender's then standard price
for  furnishing  Borrower or its designees  copies of any  statements,  records,
files or other data  (collectively,  "Reports")  requested  by  Borrower  or its
designees,  other than  reports of the kind  furnished  to Borrower and Lender's
other borrowers on a regular,  periodic basis in the ordinary course of Lender's
business.  Borrower shall also pay Lender's  customary bank charges,  including,
without  limitation,  all wire transfer  fees  incurred by Lender,  for all bank
services  performed  or  caused  to be  performed  by  Lender  for  Borrower  at
Borrower's  request.  All such  costs and  expenses  together  with all  filing,
recording  and search  fees,  taxes and  interest  payable by Borrower to Lender
shall be payable on demand and shall be secured by the Collateral. If any tax by
any  governmental  authority  is or  may be  imposed  on or as a  result  of any
transaction  between  Borrower  and Lender which Lender is or may be required to
withhold  or pay,  Borrower  agrees to  indemnify  and hold  Lender  harmless in
respect of such taxes,  and Borrower will repay to Lender the amount of any such
taxes which shall be charged to Borrower's  account;  and until  Borrower  shall
furnish  Lender  with  indemnity   therefor  (or  supply  Lender  with  evidence
satisfactory  to it that due provision  for the payment  thereof has been made),
Lender may hold without interest any balance  standing to Borrower's  credit and
Lender shall retain its security  interests in any and all Collateral.  Borrower
hereby acknowledges that Lender shall not be liable in any manner whatsoever for
any selling expenses,  orders, purchases or contracts of any kind resulting from
any  transaction  between  Borrower and any other  Person,  and Borrower  hereby
indemnifies  and holds Lender  harmless with respect  thereto,  which  indemnity
shall survive termination of this Agreement.

                                  15.  Assignment.  Lender may assign any or all
of the  Obligations  together  with any or all of the security  therefor and any
transferee  shall  succeed  to all of  Lender's  rights  with  respect  thereto.
Borrower shall be promptly notified of any such assignment.  Notwithstanding the
foregoing,   Lender  shall  not  knowingly  Transfer  the  Obligations  (or  any
substantial portion thereof) to any person or entity (i) whose primary source of
revenue is from gas or oil  production  and (ii) with whom  Borrower's  business
materially competes in conflict of Borrower's interest.  As used in this Section
15,  "Transfer"  shall mean a voluntary  sale,  assignment  or  conveyance  to a
separate legal entity from the Lender and no Transfer shall occur as a result of
merger,  acquisition,  consolidation or by operation of law. Upon such transfer,
Lender  shall be released  from all  responsibility  for the  Collateral  to the
extent same is assigned to any transferee.  Lender may from time to time sell or
otherwise grant  participations  in any of the Obligations and the holder of any
such participation  shall,  subject to the terms of any agreement between Lender
and such holder,  be entitled to the same benefits as Lender with respect to any
security for the  Obligations  in which such holder is a  participant.  Borrower
agrees that each such holder may exercise  any and all rights of banker's  lien,
set-off and counterclaim with respect to its participation in the Obligations as
fully as though Borrower were directly  indebted to such holder in the amount of
such  participation.  Borrower  may not assign or transfer  any of its rights or
obligations  under this Agreement  without the prior written  consent of Lender,
and no such assignment or transfer of any such obligation shall relieve Borrower
thereof  unless  Lender  shall  have  consented  to such  release  in a  writing
specifically referring to the obligation from which Borrower is to be released.

                                  16. Waivers.  Borrower waives  presentment and
protest of any  instrument and notice  thereof,  notice of default and all other
notices to which Borrower might otherwise be entitled.

                                  17. Term of  Agreement.  Lender may  terminate
this Agreement at any time upon one hundred and twenty (120) days' prior written
notice to Borrower. If not so terminated,  this Agreement shall continue in full
force  and  effect  until  the  expiration  of  the  Term.  The  Term  shall  be
automatically extended for successive periods of one (1) year each unless either
party shall have  provided the other with a written  notice of  termination,  at
least  ninety  (90) days  prior to the  expiration  of the  initial  Term or any
renewal Term.  The Borrower may terminate  this Agreement at any time upon sixty
(60) days' prior written notice ("Termination Date") upon payment in full of the
Obligations;  provided, that Borrower pays an early termination fee in an amount
equal to the Required  Percentage  of the  Reducing  Facility  Amount.  Reducing
Facility Amount shall mean $10,000,000, plus the outstanding balance of the Term
Loan as of the date of  termination  (without  giving effect to any  prepayments
made on the Term Loan). For the purposes hereof,  Required Percentage shall mean
(a) 3% from the Closing Date through November 29, 2001, (b) 2% from November 30,
2001  through  November  29,  2002 and (c) 1% from  November  30,  2002  through
November 29, 2003 and during any year of any renewal Term.

                                  18. Events of Default.  The  occurrence of any
of the following shall constitute an Event of Default:

                                  (a)  failure  to  make  payment  of any of the
Obligations when required hereunder;

                                  (b)  failure  to pay any taxes when due unless
such taxes are being contested in good faith by appropriate proceedings and with
respect to which adequate reserves have been provided on Borrower's books;

                                  (c) failure to perform under and/or committing
any breach of this Agreement or any Ancillary  Agreement or any other  agreement
between  Borrower and Lender or failure to perform any  non-monetary  obligation
with respect to which a cure is expressly permitted hereunder within thirty (30)
days following the occurrence of such failure;

or Equipment is located;

                                  (e) any representation,  warranty or statement

Borrower's  assets having an aggregate value in excess of $250,000,or a judgment
is rendered against Borrower or any of Borrower's property involving a liability
of more than $250,000, which shall not have been vacated, discharged,  stayed or
bonded pending appeal or  reconsideration  within sixty (60) days from the entry
thereof;

                                  (g) any  change  in  Borrower's  condition  or
affairs (financial or otherwise) which in Lender's  reasonable belief materially
impairs the Collateral or the ability of Borrower to perform its Obligations;

                                  (h) any lien  created  hereunder  or under any
Ancillary  Agreement for any reason ceases to be or is not a valid and perfected
lien having a first priority  interest other than as to assets which are subject
to Permitted Liens which are purchase money security interests,  but only to the
extent Lender's lien is not a first priority security interest in such assets;

                                  (i) Borrower shall (i) apply for or consent to
the  appointment  of, or the taking of  possession  by, a  receiver,  custodian,
trustee or liquidator of itself or of all or a substantial part of its property,

                                  (l)  Borrower  directly or  indirectly  sells,
assigns,  transfers,   conveys,  or  suffers  or  permits  to  occur  any  sale,
assignment,  transfer or  conveyance  of any assets of Borrower or any  interest
therein, except as permitted herein;

                                  (m) Borrower  fails to operate in the ordinary
course of business;

                                  (n) Lender  shall in good  faith  deem  itself
insecure or unsafe or shall have a reasonable  belief that there is or will be a
material diminution in value, removal or material waste of the Collateral;

                                  (o) a default by Borrower in the payment, when
due, of any principal of or interest on any  indebtedness  for money borrowed in
excess of $250,000;

                                  (p) any Change of Ownership; or

                                  (q) The  occurrence  of any default  under the
Conoco  Indemnification  Agreement  which would have the effect of impairing the
enforceability or financial benefits to Borrower of such Agreement;

                                  19.  Remedies.  (a) Upon the  occurrence of an
Event of Default  pursuant to Section 18 (i) herein,  all  Obligations  shall be
immediately due and payable and this Agreement shall be deemed terminated;  upon
the occurrence and  continuation  of any other of the Events of Default,  Lender
shall have the right to demand repayment in full of all Obligations,  whether or
not otherwise due and/or to terminate this  Agreement  without  advance  notice.
Until all  Obligations  have been  fully  satisfied,  Lender  shall  retain  its
security interest in all Collateral. Lender shall have, in addition to all other
rights and remedies provided herein,  the rights and remedies of a secured party
under the Uniform  Commercial  Code, and under other  applicable  law, all other
legal and equitable  rights to which Lender may be entitled,  including  without
limitation, the right to take immediate possession of the Collateral, to require
Borrower to assemble  the  Collateral,  at  Borrower's  expense,  and to make it
available  to  Lender  at a place  designated  by  Lender  which  is  reasonably
convenient  to both  parties  and to enter any of the  premises  of  Borrower or
wherever the  Collateral  shall be located,  with or without force or process of
law,  and to keep and store the same on said  premises  until  sold (and if said
premises shall be the property of Borrower, Borrower agrees not to charge Lender
for  storage  thereof  for a period up to at least sixty (60) days after sale or
disposition of said Collateral). Further, Lender may, at any time or times after
default by Borrower,  sell and deliver all  Collateral  held by or for Lender at
public or private sale for cash,  upon credit or  otherwise,  at such prices and
upon such terms as Lender,  in Lender's sole  discretion,  deems  advisable,  or
Lender may otherwise recover upon the Collateral in any commercially  reasonable
manner as Lender,  in its sole discretion,  deems  advisable.  Except as to that
part of the Collateral  which is perishable or threatens to decline  speedily in
value or is of a type customarily sold on a recognized  market,  the requirement
of reasonable  notice shall be met if such notice is mailed  postage  prepaid to
Borrower at Borrower's  address as shown in Lender's records,  at least ten (10)
days before the time of the event of which notice is being given.  Lender may be
the purchaser at any sale, if it is public.  In connection  with the exercise of
the foregoing  remedies,  Lender is granted  permission to use all of Borrower's
trademarks,  trade names, trade styles, patents, patent applications,  licenses,
franchises and other  proprietary  rights which are used in connection  with (a)
Inventory  for the purpose of disposing of such  Inventory and (b) Equipment for
the purpose of completing the manufacture of unfinished  goods.  The proceeds of
sale shall be applied first to all costs and expenses of sale, including but not
limited to attorneys'  fees, and second to the payment (in whatever order Lender
elects) of all  Obligations.  Lender  will  return any  excess to  Borrower  and
Borrower shall remain liable to Lender for any deficiency.

                                  20. Waiver;  Cumulative  Remedies.  Failure by
Lender to  exercise  any right,  remedy or option  under this  Agreement  or any
supplement hereto or any other agreement between Borrower and Lender or delay by
Lender in exercising the same, will not operate as a waiver; no waiver by Lender
will  be  effective  unless  it is in  writing  and  then  only  to  the  extent
specifically  stated.  Lender's rights and remedies under this Agreement will be
cumulative and not exclusive of any other right or remedy which Lender may have.

                                  21.   Application   of   Payments.    Borrower
irrevocably  waives the right to direct the  application of any and all payments
at any time or times hereafter  received by Lender from or on Borrower's behalf,
and Borrower  hereby  irrevocably  agrees that Lender shall have the  continuing
exclusive  right to apply and reapply any and all payments  received at any time
or times hereafter against  Borrower's  Obligations  hereunder in such manner as
Lender  may deem  advisable  notwithstanding  any  entry by  Lender  upon any of
Lender's books and records.  In the event that Lender shall elect to reapply any
payments hereunder, Lender will not perform such reapplication in a manner which
would result in a payment default under the Term Loan.

                                  22. Depository Accounts.  Any payment received
by Borrower on account of any Collateral  shall be held by Borrower in trust for
Lender,  and Borrower shall  promptly  deliver same in kind to Lender or deposit
all such  payments  into a cash  collateral  account  at such bank as Lender may
designate for  application  to payment of the  Obligations.  Borrower shall also
execute such further documents as Lender may deem necessary to establish such an
account and all funds  deposited in such  account  shall  immediately  be deemed
Lender's property.

                                  23.  Lock Box  Accounts.  Borrower  shall,  at
Lender's request, instruct all of its Customers to make such payments on account
of Receivables to an account under Lender's dominion and control at such bank as
Lender may  designate.  Borrower  shall also execute  such further  documents as
Lender may deem necessary to establish such an account,  and all funds deposited
in such account shall immediately be deemed Lender's property.

                                      -39-
<PAGE>

                                  24. Revival.  Borrower  further agrees that to
the extent  Borrower  makes a payment or  payments to Lender,  which  payment or
payments  or any part  thereof  are  subsequently  invalidated,  declared  to be
fraudulent or preferential, set aside and/or required to be repaid to a trustee,
receiver or any other  party under any  bankruptcy  act,  state or federal  law,
common law or equitable cause, then, to the extent of such payment or repayment,
the  obligation  or part thereof  intended to be satisfied  shall be revived and
continued in full force and effect as if said payment had not been made.


<PAGE>


                                  25.  Syndication.  Borrower  acknowledges that
after  the date  hereof,  Lender  may at any time and from  time to time  select
additional  Co-Lenders to make Loans to Borrower under this  Agreement,  so that
this  Agreement  shall then  constitute a syndicated  credit  facility.  In such
event, the term "Lender" for all purposes of this Agreement,  as well as each of
the other Ancillary  Agreements,  shall instead refer to GMAC as agent,  for the
benefit of itself  and each and all of the other  Co-Lenders  ("Agent").  In any
such  case,  the  Agent  shall  exclusively  make all  determinations  as to the
management,  handling and  enforcement  of this  Agreement in all  respects,  on
behalf of itself and each of the other  Co-Lenders,  subject  to no  limitations
whatsoever.  Without  limiting the  foregoing:  (a) the term "Lender" shall mean
each and all of the Co-Lenders in the syndicated  facility,  including,  without
limitation, GMAC or any successor in interest to GMAC, the Agent itself and each
of the other Co-Lenders;  (b) each and all of the  representations,  warranties,
covenants,  Collateral  and  agreements,  protections,  guarantees,  rights  and
remedies  referred to or otherwise set forth in this Agreement and the Ancillary
Agreements are to run for the benefit of the Agent, on behalf of itself and each
other  Co-Lender;  and (c) each Co-Lender is accordingly also to have all of the
rights, security interests, remedies and other benefits and protections provided
to the  Lender  in  this  Agreement  and the  Ancillary  Agreements,  except  as
otherwise set forth in this Agreement.  Each Co-Lender is also to acknowledge in
writing,  to the Agent,  the Borrower and each of the other  Co-Lenders (if any)
and in a manner  satisfactory  to the Agent and the Borrower (in the case of the
Borrower on the condition that the Borrower shall not unreasonably  withhold its
approval thereto), that it shall be a party to this Agreement as a Co-Lender and
that  it  shall  have  all of the  responsibilities  of the  Lender  under  this
Agreement  and the  Ancillary  Agreements  of the Lender and of a  Co-Lender  in
accordance with the pertinent provisions thereof, including, without limitation,
the manner of the handling of the Loans and the maximum  principal dollar amount
of Loans which each such Co-Lender  shall be obligated to extend as Loans to the
Borrower as their respective Commitment. Moreover, in any case where an Agent is
acting for itself and other Co-Lenders  hereunder,  the Borrower agrees to cause
any guarantors to execute and deliver such additional  documentation as GMAC, as
Agent (or any successor  Agent) may request at any time and from time to time in
order to reflect or evidence that each and all of their  respective  guarantees,
whether now existing or hereafter arising, run for the benefit and protection of
the Agent,  on behalf of itself and the other  Co-Lenders  and include,  without
limitation,  all Loans due or to become  due to each and all of the  Co-Lenders;
provided,  however, that such documentation shall permit the payment to Agent on
behalf of Co-Lenders and shall not increase the aggregate liability  thereunder.
In the event that such a syndicated facility may exist by reason of the addition
of any  Co-Lender(s),  GMAC (or any successor Agent as provided for below) is to
act in the capacity of Agent under such  syndicated  Agreement,  for itself as a
Co-Lender entitled to all of the rights and benefits of a Co-Lender and for each
and  all  of the  other  Co-Lenders  under  this  Agreement  and  the  Ancillary
Agreements.  Without limiting the generality of the foregoing, in the event that
a  syndicated  facility  may  exist  hereunder  by reason  of the  existence  of
Co-Lenders,  no  Co-Lender  other  than  Agent  shall  have the right to conduct
audits,  declare an Incipient Event of Default or an Event of Default or conduct
due diligence in accordance with this Agreement,  establish,  set,  maintain and
adjust  reserves or reserve  requirements  to the same extent that the Lender is
permitted when a syndicated  facility does not exist. As of the Closing Date and
in relation to any such Agent/Co-Lender  arrangements,  the following additional
provisions are to supplement this Agreement:


                                      -40-
<PAGE>

                                  (a) Agent and Co-Lender  Provisions.  Borrower
recognizes  that after the  Closing  Date,  the Lender  may,  in  Lender's  sole
discretion:  (i) select additional Co-Lenders at any time and from time to time;
and (ii) resign at any time as Agent,  provided that such  resignation  complies
with the terms of this Section 25 (a).

                                  Should   the  Agent,   whether   GMAC  or  any
successor  Agent,  serve  under  this  Agreement  and act for  itself  and other
Co-Lenders  as to the Loans,  the  following  supplemental  provisions  shall be
applicable  and shall survive the  termination  of any such  Co-Lender or agency
relationships:

                                         (1) Authorization  and Action.  Each of
the  Co-Lenders  hereby  irrevocably   appoints  and  authorizes  the  Agent  to
exclusively  take all actions as Agent on its behalf and to exercise all rights,
powers and remedies  under this  Agreement as are delegated to the Lender or the
Agent by the terms thereof as modified herein, together with such rights, powers
and remedies as are reasonably  incidental  thereto.  The duties of the Agent to
each Co-Lender  shall be mechanical and  administrative  in nature and the Agent
shall not by reason of this  Agreement  or otherwise be a trustee or a fiduciary
for any of the  Co-Lenders.  The Agent shall have no duties or  responsibilities
except those expressly set forth herein.  The Agent shall be fully authorized to
act or to refrain  from  acting at any time and from time to time in  accordance
with its sole discretion  under the terms and provisions of this Agreement,  the
Ancillary Agreements and each of them. The Agent may at all times act or refrain
from acting  without any  requirement  of seeking the approval or the consent of
any of the Co-Lenders.  As to all matters set forth in this Agreement, the Agent
shall not be required  to exercise  any  discretion  or take any action,  but as
noted herein shall be  authorized to act or to refrain from acting (and shall be
fully protected in so acting or so refraining from acting) upon the instructions
of the  Majority  Lenders,  and  such  instructions  shall be  binding  upon all
Co-Lenders;  provided, however, that the Agent shall not be required to take any
action  which  exposes the Agent to personal  liability  or which is contrary to
this Agreement or applicable law. It is agreed that the Agent may perform any of
its duties hereunder by or through its officers, directors, agents or employees.


                                      -41-
<PAGE>


                                         (2) Liability of Agent. The Agent shall
have no duties or  responsibilities  except  those  expressly  set forth in this
Agreement.  Neither  the Agent  nor any of its  directors,  officers,  agents or
employees  shall be liable for any action  taken or omitted to be taken by it or
them under or in connection  with this  Agreement as Agent in the absence of its
or their own gross  negligence  or  willful  misconduct.  Without  limiting  the
foregoing,  the Agent: (A) may consult with legal counsel (including counsel for
the Borrower),  independent  public accountants and other experts selected by it
and shall not be liable  for any  action  taken or  omitted  to be taken in good
faith by it in  accordance  with the  advice  of such  counsel,  accountants  or
experts;  (B) makes no warranty or representation to any Co-Lender and shall not
be   responsible   to  any   Co-Lender   for  any   statements,   warranties  or
representations made in or in connection with this Agreement; (C) shall not have
any duty to ascertain or to inquire as to the  performance  or observance of any
of the terms,  covenants,  or conditions  of this  Agreement on the apart of the
Borrower,  or to inspect the property  (including  the books and records) of the
Borrower;  (D) shall not be  responsible to any Co-Lender for the due execution,
legality, validity,  enforceability,  genuineness,  perfection,  sufficiency, or
value of this Agreement or any other instrument or document  furnished  pursuant
thereto;  and (E) shall incur no liability under or in respect of this Agreement
by acting upon any notice,  consent,  certificate or other instrument or writing
(which may be by telegram,  telex, or facsimile  transmission) believed by it to
be genuine and signed or sent by the proper party or parties.  Without  limiting
the foregoing, the Agent shall have no obligation whatsoever to any of the other
Co-Lenders  or to any other  Person to assure that the  Collateral  exists or is
owned by the  Borrower or is cared for,  protected  or insured or that the Liens
granted  to  the  Agent  herein  or  pursuant   hereto  have  been  properly  or
sufficiently  or  lawfully  created,  perfected,  protected  or  enforced or are
entitled to any particular priority, or to exercise or continue exercising,  any
of the rights,  authorities and powers granted or available to the Agent in this
Agreement, it being understood and agreed that in respect of the Collateral,  or
any act,  omission or event related thereto,  the Agent may act in any manner it
may deem appropriate, in its sole discretion,  given the Agent's own interest in
the Collateral as one of the Co-Lenders.

                                         (3)  Rights of Agent as a Lender.  With
respect to its making of Loans  under this  Agreement,  the Agent shall have the
same rights and powers  under this  Agreement as if and to the same extent as if
the same ran directly to itself or any other Co-Lender and may exercise the same
in the place and stead of each such  Co-Lender  as though it were not the Agent;
and the term  "Lender",  "Co-Lender" or  "Co-Lenders"  shall  therefore,  unless
otherwise expressly indicated, include the Agent in its individual capacity. The
Agent and its Affiliates may accept deposits from, lend money to, act as trustee
under  indentures  of, and  generally  engage in any kind of  business  with the
Borrower,  its  Subsidiaries  or Affiliates,  and any Person who may do business
with or own  securities  of the Borrower or any  Subsidiary  or Affiliate of the
Borrower, all as if the Agent were not the Agent and without any duty to account
therefor to the Co-Lenders.

                                         (4) Independent Credit Decisions.  Each
of the  Co-Lenders  shall  acknowledge  that it has,  independently  and without
reliance  upon the Agent or any of the  other  Co-Lenders  and  based  upon such
documents  and  information  as it has  deemed  appropriate,  shall make its own
credit  analysis and decision to enter into this Agreement as a Co-Lender and to
be bound by all of the terms and provision hereof,  each of the Co-Lenders shall
also acknowledge that it will, independently and without reliance upon the Agent
or any of the other Co-Lenders and based on such documents and information as it
shall deem appropriate,  at the time,  continue to make its own credit decisions
in taking or not taking action under this Agreement. Except for notices, reports
and other  documents and information  expressly  required to be furnished to the
Co-Lenders   by  the  Agent   hereunder,   the  Agent  shall  have  no  duty  or
responsibility  to  provide  any of the  Co-Lenders  with  any  credit  or other
information  concerning  the affairs,  financial  condition,  or business of the
Borrower, or any Subsidiary or any Affiliate of the Borrower which may come into
the possession of the Agent or any of its Affiliates.

                                         (5)      General      Immunity      and
Indemnification.  Neither the Agent nor any of its directors,  officers, agents,
attorneys or employees  shall be liable to any Co-lender for any action taken or
omitted to be taken by it or them  hereunder or in connection  herewith,  except
for its or their own willful  misconduct  or gross  negligence.  The  Co-Lenders
agree to  indemnify  the Agent (to the extent not  reimbursed  by the  Borrower)
ratably  according  to the  respective  amounts of their  Commitments,  from and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
actions,  judgments,  suits,  costs,  expenses or  disbursements  of any kind or
nature  whatsoever which may be imposed on, incurred by, or asserted against the
Agent in any way  relating  to or arising out of this  Agreement,  or any action
taken or omitted by the Agent under this  Agreement,  provided  that none of the
Co-Lenders  shall be liable for any  portion of any of the  foregoing  resulting
from the Agent's gross negligence of willful  misconduct.  Without limitation of
any of the foregoing,  each of the Co-Lenders  agrees to reimburse the Agent (to
the extent not reimbursed by the Borrower)  promptly upon demand for its ratable
share of any  out-of-pocket  expenses  (including  counsel fees) incurred by the
Agent in connection with the preparation,  administration, or enforcement of, or
legal advice in respect of, rights or  responsibilities  under or in relation to
this Agreement.  The Borrower  unconditionally  and without limitation agrees to
indemnify,  defend and hold harmless the Agent,  on its own behalf and on behalf
of each of the  other  Co-Lenders,  from and  against  any and all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements of any kind or nature  whatsoever,  arising out of any
litigations, investigations, claims or proceedings, pending or threatened, which
may be imposed on,  incurred by, or asserted  against any of such  Co-Lenders or
the  Agent  in any way  relating  to or  arising  out of the  Borrower  and this
Agreement  and the Ancillary  Agreements  but not arising out of a dispute among
any of the Co-Lenders, Lender or the Agent, provided that the Borrower shall not
be liable  for any  portion  of any of the  foregoing  resulting  from the gross
negligence or willful misconduct of the Agent or the Co-Lender,  as the case may
be; this indemnity  shall survive any  termination of this Agreement and payment
in full of the Obligations. Without limitation of any of the foregoing, Borrower
unconditionally agrees to reimburse the Agent and the Co-Lenders,  promptly upon
demand in full, for any and all out-of-pocket  expenses  (including counsel fees
of the Agent)  incurred by the Agent in connection  with the enforcement of this
Agreement  as to the  Borrower.  In  determining  whether to become a  Co-Lender
hereunder it is recognized that certain  out-of-pocket  expenses may be incurred
by prospective  Co-Lenders (other than the Agent); the Borrower  unconditionally
agrees to reimburse the Agent and each such prospective  Co-Lender promptly upon
demand in full for any and all out-of-pocket expenses (including counsel fees of
each such prospective Co-Lender) incurred in connection with such review.

                                         (6)  Successor  Agent.   GMAC  and  any
successor Agent(s) (each, the "Agent") may resign at any time by giving at least
30 days' prior written notice  thereof to the  Co-Lenders and the Borrower.  Any
successor  Agent shall be a member of the New York Clearing  House, or any other
bank or other financial institution with assets of at least $1 Billion. Upon the
acceptance of any  appointment  as Agent  hereunder by a successor  Agent,  such
successor  Agent shall  thereupon  succeed to and become  vested with all of the
rights, powers,  privileges,  and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and  obligations  under or in relation
to this  Agreement.  After  retiring,  or the  Agent's  resignation  or  removal
hereunder as Agent, the provisions of this subsection shall inure to its benefit
as to any  actions  taken or omitted to be taken by it while it was Agent  under
this Agreement. In the case of any such removal or resignation, however, nothing
contained in this paragraph, is or shall be deemed to limit or change any duties
or responsibilities that the Agent may otherwise have to Borrower as a Co-Lender
under this Agreement,  which limitations or changes may only occur in accordance
with other pertinent terms and provisions hereof.

                                         (7)  Revolving  Credit.   Each  of  the
Co-Lenders  severally  agree,  on the  terms  and  conditions  set forth in this
Agreement,  to make Loans to the  Borrower  from time to time  during the period
from the date of their respective  Commitment as a Co-Lender hereunder up to and
including  the last  day of the Term in an  aggregate  principal  amount  not to
exceed at any time  outstanding the amount set opposite such Co-Lender's name in
a written  acknowledgment  satisfactory to Agent and to Borrower,  provided that
the Borrower shall not unreasonably withhold approval thereof,  confirming their
respective undertaking to become a Co-Lender hereunder and to be bound by all of
the terms and provisions  hereof,  as such amount may be reduced pursuant to the
provisions  hereof dealing with  "reduction of  Commitment".  The Agent may, but
shall  not be  obligated  to,  advance  Loans on  behalf  of each and all of the
Co-Lenders to the Borrower.  It is understood  that the obligation of Co-Lenders
to  fund  Loans   hereunder   shall  be  irrevocable  and  not  subject  to  any
qualification  or exception  whatsoever and shall be made in accordance with the
terms  and  conditions  of this  Agreement  under all  circumstances,  including
without  limitation any lack of validity or  enforceability of this Agreement or
any of the Ancillary Agreements,  the existence of any claim, setoff, defense or
other  right which the  Borrower  or any third  party may have at any time,  any
statement of the Borrower or any third party being untrue or  inaccurate  in any
respect,  the surrender or impairment of any Collateral  for the  performance or
observance  of  this  Agreement  or  any  of  the  Ancillary  Agreements  or the
occurrence  of any Incipient  Event of Default or Event of Default.  Each of the
Loans as to which a Co-Lender has so  acknowledged  its  willingness  to co-lend
hereunder  shall be made  available  to the Agent by each of the  Co-Lenders  in
accordance with the terms of this  Agreement,  and shall be remitted in a timely
manner in the proportion that  Co-Lender's  Commitment bears to the total amount
of all the Co-Lenders'  Commitments  hereunder.  Without limiting the foregoing,
each Co-Lender agrees that by no later than the day of each Revolving Loan to be
made  to the  Borrower,  it  shall  deposit  its  pro  rata  share  thereof,  in
immediately  available  funds, in the Borrower's Loan Account with the Agent, or
in such other account satisfactory to the Agent as the Borrower may from time to
time designate. Within the limits of their respective Commitments,  the Borrower
may borrow, repay and reborrow under the revolving Loans.

                                  The  failure  of any  Co-Lender  to  make  any
requested  Revolving  Loan to be made by it on the date specified for such Loan,
whether or not such  Co-Lender may be a Restricted  Co-Lender (as defined and as
described below),  shall not relieve it or any other Co-Lender of its respective
obligation  (if  any)  to  make  Loans  hereunder,  but no  Co-Lender  shall  be
responsible  for the failure of any other  Co-Lender to make Loans to be made by
such other Co-Lender(s).  In the event,  however,  that any particular Co-Lender
decides  not to fund any of the Loans to the  Borrower in  accordance  with this
Agreement,  by  reason  of  any  Federal  or  State  banking  agency  regulatory
supervision, limits, constraints or other restrictions applicable to the overall
business  operations  of Co-Lender,  and arises  strictly in relation to general
regulatory   difficulties   or  concerns   applicable  to  that  Co-Lender  (the
"Restricted Co-Lender"),  then: (y) the Restricted Co-Lender unconditionally and
irrevocably  agrees  with the Agent  that the Agent  shall,  following  any such
failure to fund,  have the right at any time to seek to  replace  and to replace
that  Restricted  Co-Lender  with another  Co-Lender  under this  Agreement,  or
alternatively,  the  Agent  itself,  may be  substituted  in the  place  of such
Restricted  Co-Lender.  Under  such  circumstances,  upon any  such  replacement
occurring  and upon  payment  to the  Restricted  Co-Lender  by any  replacement
Co-Lender,  or by the Agent,  of the principal  balance of all Loans owed to the
Restricted  Co-Lender,  together  with all  accrued  interest  thereon:  (A) the
Restricted  Co-Lender  shall no longer act as a Co-Lender to the Borrower  under
this Agreement; and (B) simultaneously, the Restricted Co-Lender shall be deemed
to have fully released and  discharged  the Agent,  the Borrower and each of the
Co-Lenders  from any and all  obligations,  claims and  liabilities  under or in
relation to this  Agreement  (but this shall not release or be deemed to release
the  Restricted  Co-Lender  from any claims,  liabilities  or obligations to the
Agent, the other Co-Lenders, or to the Borrower by reason of the lack of funding
or any  related  matters);  and (z) if and to the extent that the  Borrower  may
certify in writing  to the Agent that the lack of funding of the  Borrower  by a
Restricted Co-Lender may materially and adversely affect the Borrower's business
operations and for so long as necessary  until  arrangements  with a replacement
Co-Lender  may be put into place,  the Agent agrees to fund any  amount(s)  that
otherwise were to have been funded by the  Restricted  Co-Lender and to increase
the amount of the Agent's  Commitment  to the Borrower  accordingly,  until such
time, if any, as replacement Co-Lender arrangements may be finalized.

                                         (8)  Loan  Account.   The  Agent  shall
maintain a loan  account  ("Loan  Account")  in which shall be recorded  (i) all
Loans made by the Agent on behalf of the Co-Lenders to the Borrower  pursuant to
this  Agreement,  (ii) all payments made by the Borrower on all such Loans,  and
(iii) all other  appropriate  debits and credits as provided in this  Agreement,
including without  limitation,  all fees,  charges,  expenses and interest.  All
entries in the  Borrower's  Loan Account  shall be made in  accordance  with the
Agent's customary accounting practices as in effect from time to time.

                                         (9) Notice and Manner of Borrowing. The
Borrower  shall give the Agent a Notice of Borrowing  under this  Agreement,  at
least on (1) Business Day before each request for a Revolving Loan,  specifying:
(i) the date of such requested Loan; and (ii) the amount of such Loan. The Agent
shall promptly  notify each Co-Lender of each such Notice.  Not later than 12:00
a.m. (New York Time) on the date of such  Revolving  Loans,  each Co-Lender will
make  available to the Agent such  Co-Lender's  pro rata share of such Revolving
Loans.  After the  Agent's  receipt of such funds not later than 4:00 p.m.  (New
York  time) on the date of such  Revolving  Loans,  the  Agent  will  make  such
requested  Revolving  Loan  available to the Borrower in  immediately  available
funds, up to an aggregate  outstanding amount at any time and from time to time,
not to exceed the Maximum  Loan Amount by  crediting  the amount  thereof to the
Borrower's  Loan Account at the Payment  Office or into  another  account of the
Borrower  specifically  designated by the Borrower on the date and in the amount
set forth in the applicable Notice of Borrowing.

                                         (10)  Nonreceipt  of  Funds  by  Agent.
Unless the Agent shall have received  notice from a Co-Lender  prior to the date
on which such Co-Lender is to provide funds to the Agent for a Loan to be and by
such  Co-Lender  that such  Co-Lender  will not make available to the Agent such
funds, the Agent may assume that such Co-Lender has made such funds available to
the  Agent on the date of such Loan in  accordance  with the  provisions  hereof
entitled "Notice and Manner of Borrowing",  and the Agent in its sole discretion
may,  but shall not be  obligated  to, in reliance  upon such  assumption,  make
available to the  Borrower on such date a  corresponding  amount.  If and to the
extent that such  Co-Lender  shall not have so made such funds  available to the
Agent,  such  Co-Lender  agrees to repay to the Agent  forthwith  on demand such
corresponding  amount together with interest thereon, for each day from the date
such  amount is made  available  to the  Borrower  until the date such amount is
repaid to the Agent,  at the customary  rate set by the Agent for the correction
of errors among  correspondent  banks for three  Business Days and thereafter at
the  Alternate  Base  Rate.  If such  Co-Lender  shall  repay to the Agent  such
corresponding  amount  forthwith,  such amount so repaid shall  constitute  such
Co-Lender's Loan for purposes of this Agreement.  If such Co-Lender does not pay
such  corresponding  amount  forthwith upon Agent's demand  therefor,  the Agent
shall promptly notify the Borrower,  and the Borrower shall immediately pay such
corresponding  amount to the Agent with interest thereon,  for each day from the
date such amount is made available to the Borrower until the date such amount is
repaid to the  Agent,  at the rate of  interest  applicable  at the time to such
proposed Loan.

                                  Unless the Agent  shall have  received  notice
from  the  Borrower  prior  to the  date  on  which  any  payment  is due to the
Co-Lenders  hereunder  that the Borrower will not make such payment in full, the
Agent may assume that the Borrower has made such payment in full to the Agent on
such date and the Agent in its sole  discretion  may, but shall not be obligated
to, in reliance upon such assumption,  cause to be distributed to each Co-Lender
on such due date an amount  equal to the amount then due to such  Co-Lender.  If
and to the extent the  Borrower  shall not have so made such  payment in full to
the Agent,  each  Co-Lender  shall repay to the Agent  forthwith  on demand such
amount  distributed to such Co-Lender  together with interest thereon,  for each
day from the date such amount is distributed  to such  Co-Lender  until the date
such Co-Lender repays such amount to the Agent, at the customary rate set by the
Agent for the correction of errors among  correspondent banks for three Business
Days and thereafter at the Alternate Base Rate. All of the provisions  contained
in this  subsection  (k) shall,  however,  be subject  to the  provisions  above
dealing with any Restricted Co-Lender(s).

                                         (11) Amendment, Termination, Waiver and
Action by the Agent. No Amendment,  modification,  termination, or waiver of any
provision of this  Agreement  or any of the  Ancillary  Agreements  to which the
Borrower is a party,  nor consent to any  departure by the Borrower  from any of
the Ancillary Agreements to which it is a party, shall in any event be effective
unless  the same shall be in  writing  and  signed by the  Agent,  and then such
waiver or consent shall be effective  only in the specific  instance and for the
specific purpose for which given; provided,  however, that except to the limited
extent  specifically  and  affirmatively  required  by the terms and  provisions
hereof, the Agent is at liberty and without any applicable restriction,  to act,
or to omit to act, to enforce or to refrain from  enforcing,  in accordance with
the terms and  provisions of this  Agreement,  without any notice to and without
obtaining any consent or approval of any of the Co-Lenders hereunder.  The Agent
need not take any action hereunder and no amendment,  waiver or consent shall be
called for to be entered into by the Agent hereunder.

                                         (12)    Execution   and   Delivery   of
Supplemental  Documents and Action.  Borrower agrees at the request of the Agent
made at any time  and  from  time to time  to:  (a)  execute  and to cause to be
delivered  to the Agent,  on behalf of itself  and each of the other  Co-Lenders
hereunder such further  documentation  as the Agent or any of the Co-Lenders may
deem  reasonably  necessary or  desirable  in order to  implement  the terms and
provisions hereof; and (b) take such reasonable  additional steps and actions as
the Agent requests for any of such purposes.

                                         (13)   Confidentiality.   Each  of  the
Co-Lenders  agrees to be bound in all  respects by the terms and  provisions  of
this Agreement,  including  without  limitation all  confidentiality  provisions
hereof and the Co-Lenders  shall keep  confidential  all information  which this
Agreement states is not to be disseminated and shall otherwise fully comply with
all confidentiality requirements of this Agreement.

                                         (14) Fees and Entitlements. Each of the
Co-Lenders  agree that they shall not be  entitled to receive any portion of any
fees, charges or any other compensation which the Agent is or at any time may be
entitled to charge or receive under or in relation to this  Agreement,  or under
or in relation to any other  agreement or arrangement  that the Agent may now or
hereafter have with or concerning the Borrower,  or any of its  Subsidiaries  or
Affiliates.  As their  exclusive  entitlement  as a  Co-Lender  and in any other
capacity  under or in  relation  to this  Agreement  or  otherwise,  each of the
Co-Lenders  other than the Agent shall each be entitled solely to the payment of
principal  and  interest  due  or to  become  due  under  the  Revolving  Loans,
corresponding  to  payments  made in  relation  to  Loans  made to the  Borrower
hereunder pursuant to the respective Commitments of each such Co-Lender.

                                         (15)  Counterparts.  Any  agreement  or
consent of the Co-Lenders may be executed in any number of  counterparts  and by
different   Co-Lenders   and  other  parties  to  this   Agreement  in  separate
counterparts,  each of which when so executed  shall be deemed to be an original
and all of  which  when  taken  together  shall  constitute  one  and  the  same
agreement.

                                         (16)  Statements.   All  Loans  to  the
Borrower, and all other debits and credits provided for in this Agreement, shall
be evidenced by entries made by the Agent in its internal  data control  systems
showing  the date,  amount and reason for each such debit or credit.  Until such
time as the Agent shall have  rendered to the  Borrower  written  statements  of
account as provided herein,  the balance in the Borrower's Loan Account,  as set
forth in the  Agent's  most recent  printout,  shall be  rebuttably  presumptive
evidence of the amounts due and owing the Co-Lenders by the Borrower. Each month
the Agent shall render to the Borrower a statement  setting forth the balance of
the Borrower's Loan Account, including principal,  interest,  expenses and fees.
Each such  statement  shall be subject to  adjustment  by the Agent,  but shall,
absent  manifest errors or omissions,  be presumed  correct and binding upon the
Borrower and shall  constitute an account stated unless,  within sixty (60) days
after receipt of any statement from the Agent, the Borrower shall deliver to the
Agent  written  objection  thereto  specifying  the  error  or  errors,  if any,
contained in such statement.

                                         (17)  Defaults/Action by Agent.  Should
an Event of  Default  exist or occur  which  may be  declared  hereunder  at the
Agent's option, the Agent shall at the written election to that effect delivered
to the Agent by the Majority  Lenders,  declare such an Event of Default to have
occurred under this Agreement. For all purposes of this Agreement,  however, the
Agent may  assume  that no Event of Default or  Incipient  Event of Default  has
occurred and is  continuing  unless  Agent has actual  knowledge of the Event of
Default or Incipient Event of Default,  has received notice from the Borrower or
a  Co-Lender  stating the nature of the Event of Default or  Incipient  Event of
Default and in the instance where such notice is from a Co-Lender,  stating that
the Co-Lender  considers  the Event of Default or Incipient  Event of Default to
have occurred and to be continuing.

                                         Except where an affirmative  obligation
on the part of the Agent to act is specifically set forth herein,  requiring the
Agent to act,  the  Agent  may,  but  shall  not be  required  to  exercise  its
discretion  to act or not to act.  The Agent shall not be required to act or not
act if to do so would expose Agent to liability,  would be inconsistent with the
Agent's  practice in similar  situations when acting solely for its own account,
or would be contrary to this Agreement or any of the Ancillary  Agreements or to
applicable law.

                                  26. Notices.  Any notice or request  hereunder
may be given to Borrower or Lender at the  respective  addresses set forth below
or as may  hereafter be specified in a notice  designated as a change of address
under  this  paragraph.  Any  notice  or  request  hereunder  shall  be given by
registered or certified mail, return receipt requested,  or by overnight mail or

those by mail or overnight mail, deemed to have been given when deposited in the
mail or with the overnight  mail carrier,  and, in the case of a telecopy,  when
confirmed.

Exhibit 99.1

         On December 1, 1999, Greka Energy issued the following press release:

                       "GREKA CLOSES $35 MILLION FINANCING

         December  1,  1999.  NEW  YORK,  NEW  YORK - GREKA  Energy  Corporation
(NASDAQ:  GRKA) closed the financing of up to $35 million with a major financial
institution.  The financing includes a $10 million revolver to primarily operate
the Company's refinery  operations and a term note of $25 million.  The proceeds
of the term loan,  secured by the Company's  interest in certain  California oil
and gas properties and real estate, are to be used for acquisitions and payments
toward current debt of the Company.

         Mr.  Randeep  S.  Grewal,  Chairman,  CEO  &  President,  stated,  `The
Company's  closing of this  financing  that  provides  current  debt  payoff and
additional  acquisition  financing is yet another  demonstration of management's
continued  achievement  in  meeting  objectives  that  are  consistent  with our
strategy to enhance  shareholder  value.  In addition to the Company's  reported
record earnings for the last two consecutive  quarters,  this financing  further
strengthens  Greka Energy's balance sheet by substantially  reducing our current
liabilities.  We elected to wait on refinancing the Company's current debt until
such time that our cash flow and  earnings  potential  were  demonstrated.  As a
result of this strategy, the recognition of our strong operating performance has
enabled us to skip the mezzanine  layer of expensive  energy  financing and thus
attain terms that are consistent with our commitment to earnings.'

         GREKA  Energy  is an  integrated  company  focused  on  exploiting  E&P
opportunities and penetrating new niche markets utilizing proprietary technology
with  emphasis on short radius  horizontal  drilling  technology  patented by BP
Amoco (NYSE:  BPA). In addition to owning and  operating an asphalt  refinery in
California, the Company has oil and gas production,  exploration and development
activities in North America and the Far East,  with primary areas of activity in
Alberta, California, Louisiana, Texas, New Mexico, Indonesia and China.

         Except for historical  information  contained herein, the statements in
this Release are  forward-looking  statements that are made pursuant to the safe
harbor  provision  of the  Private  Securities  Litigation  Reform  Act of 1995.

prices,  product  demand,  market  competition,  risks inherent in the Company's
international operations,  imprecision of reserve estimates, the availability of

and the  Company's  ability to replace  and  exploit  its  existing  oil and gas
reserves.  These and other risks are described in the Company's Annual Report on
Form 10-KSB and in the Company's  other filings with the Securities and Exchange
Commission."
