limitations  set forth herein.  Within the limits set forth in clause (b) of the
preceding  sentence,  the Borrower may borrow, pay or prepay the Term Loan on or
after the Closing Date and prior to the Term Loan Maturity Date,  subject to the
terms,  conditions  and  limitations  set forth  herein.  Each advance under the
Revolving  Loans  and/or a  disbursement  of the Term Loan (each such advance or
disbursement  is referred to herein as a "Loan")  shall  constitute  a Base Rate
Loan and  shall be made on such  Business  Day and in such  amount  (equal  to a
minimum of $100,000.00) as the Borrower shall request by written notice given to
the Lender,  in the case of a disbursement of the Term Loan, no later than 11:00
a.m.  (Denver,  Colorado time) on the date of disbursement of the requested Term
Loan and in the case of an advance  under the Revolving  Loans,  as set forth in
Section 2.3.

         b. Notes.  The  Revolving  Loans shall be  evidenced  by the  Revolving
Credit Note dated the date hereof.  The Revolving  Credit Note shall be a master
note,  and the principal  amount of all  Revolving  Loans  outstanding  shall be
evidenced  by the  Revolving  Credit  Note or any ledger or other  record of the
Lender, which shall be presumptive evidence of the principal owing and unpaid on
the  Revolving  Credit  Note.  The Term Loan shall be evidenced by the Term Loan
Note dated the date hereof.

         c. Notice of  Borrowings.  The Borrower  shall give the Lender  written
notice  not later  than  11:00  a.m.  (Denver,  Colorado  time) on the date of a
requested  advance under the Revolving  Loan  Commitment (a  "Borrowing").  Such
notice  shall be  irrevocable,  shall in each case refer to this  Agreement  and
shall be in the form  attached  hereto as  Exhibit A. Each  notice of  Borrowing
shall be deemed a  representation  by Borrower that all conditions  precedent to
such Borrowing have been satisfied.

d.       Notes; Repayment of Loans.

         (i) The Revolving  Credit Note shall bear interest from the date of the
first  Borrowing on the  outstanding  principal  balance thereof as set forth in
Section  2.6. The Lender  shall,  and is hereby  authorized  by the Borrower to,
endorse  on  a  schedule  attached  to  the  Revolving  Credit  Note  (or  on  a
continuation of such schedule attached to such Note and made a part thereof), or
otherwise  to record in  Lender's  internal  records,  an  appropriate  notation
evidencing  the date  and  amount  of each  Revolving  Loan,  each  payment  and
prepayment of principal of the Revolving Loans,  each payment of interest on the
Revolving  Loans  and the  other  information  provided  for on  such  schedule;
provided, however, that the failure of the Lender to make such a notation or any
error  therein  shall not affect the  obligation  of the  Borrower  to repay the
Revolving  Loans made by Lender in accordance  with the terms of this  Agreement
and the Revolving Credit Note.

         (ii) The Term Loan Note shall bear  interest from the date of Borrowing
on the  outstanding  principal  balance thereof as set forth in Section 2.6. The
term of the Term Loan shall  commence as of the Closing  Date and, if not sooner
paid, the entire unpaid principal balance, all accrued and unpaid interest,  and
all other sums payable in connection with the Term Loan shall be due and payable
in full on the Term Loan Maturity Date.  Borrower shall make monthly payments of
interest on the unpaid  principal  balance of the Term Loan  pursuant to Section
2.6(b)(ii).  Commencing  on December 31, 2001,  Borrower  shall make a principal
payment on the outstanding  principal  balance of the Term Loan in the amount of
$125,000 and on the last day of each  subsequent  quarter  thereafter,  Borrower
shall make principal  payments on the outstanding  principal balance of the Term
Loan in the amount of $250,000 until the Term Loan Maturity Date.

         (iii) In addition to the foregoing,  within forty-five (45) days of the
end of each fiscal quarter and within ninety (90) days following the end of each
fiscal year, Borrower shall make principal reduction payments on the outstanding
principal  balance of the Term Loan in an amount equal to 75% of the Excess Cash
Flow calculated at such time for the preceding fiscal quarter.  Borrower, at the
time of such payment, shall provide to Lender any written evidence and financial
documentation used in calculating the Excess Cash Flow.

                                      A-7


e.       Fees.

         (a) The Borrower  agrees to pay an  origination  fee (the  "Origination
Fee") in an amount  equal to $60,000,  one-half of which has been paid to Lender
and the other half of which shall be paid on the Closing Date.

         (b) A commitment  fee (the  "Commitment  Fee") of .50% per annum on the
average daily unused amount of the  Revolving  Loans during the preceding  month
shall be payable, in arrears, on the last day of each month, commencing December
31, 2001,  and  continuing  on the last day of each month  thereafter  until the
Revolving  Credit  Maturity  Date.  The  Commitment Fee shall be computed on the
basis of the actual number of days elapsed in a year of 360 days. The Commitment
Fee due December 31,  2001,  shall be prorated  based on the number of days from
the Closing Date through December 31, 2001, divided by the number of days in the
month ending December 31, 2001.

         (c) All Fees shall be paid on the dates due, in  immediately  available
funds.  Once paid,  none of the Fees shall be  refundable  (absent a calculation
error) under any circumstances.

f.       Interest on Loans.

         The Borrower shall pay interest on the unpaid  principal amount of each
Loan from the date such Loan is made until such  principal  amount shall be paid
in full as follows:

(a)  With respect to any Base Rate Loan, at a rate per annum equal to the sum
of the Base Rate and the Base Rate Margin specified in subpart (b)(i) below,
which rate shall change when and as the Base Rate changes in accordance with
this Agreement.



                  (b)      (i)
                                                                  Base Rate Margin
                                                               
                                    Revolving Loan                200 Basis Points
                                    ----------------------------- --------------------------
                                    Term Loan                     200 Basis Points
                                    ----------------------------- --------------------------
                          (ii)      The Borrower shall pay to the Lender
                                    accrued interest on the unpaid principal
                                    balance of each Base Rate Loan on the last
                                    day of each month.


         g. Default  Interest.  If the Borrower  shall default in the payment of
the  principal  of or interest on the Loans or any other  amount due or becoming
due hereunder,  by acceleration or otherwise,  the Borrower shall on demand from
time to time pay  interest,  to the extent  permitted by law, on such  defaulted
amount up to (but not  including)  the date of actual  payment (after as well as
before judgment) at a rate per annum (computed on the basis of the actual number
of days  elapsed  over a year of 360  days)  equal to the Base Rate plus 4% (the
"Default Rate") From and after any Event of Default,  the outstanding  principal
balance of the Loans shall accrue interest at the Default Rate.

h.       Termination of Commitments.

         (a)      The  Revolving   Loan   Commitment   shall  be   automatically
                  terminated  at  5:00  p.m.,  Denver,  Colorado  time,  on  the
                  Revolving Credit Maturity Date.

         (b)      The Term Loan shall terminate at 5:00 p.m.,  Denver,  Colorado
                  time, on the Term Loan Maturity Date.

         (c)      The  Borrower  shall  pay  to  the  Lender,  on  the  date  of
                  termination, the Commitment Fee on the amount of the Revolving
                  Loan Commitment so terminated accrued through the date of such
                  termination.

i.       Prepayment.

         (a)      The  Borrower  may prepay  any Base Rate Loan in whole,  or in
                  part, at any time or times.

         (b)      Without  notice  or  demand,  if the  sum  of the  outstanding
                  principal  balance of the Loans  shall at any time  exceed the
                  Borrowing  Base,  the Borrower  shall  immediately  prepay the
                  Loans to the extent  necessary to eliminate  such excess.  Any
                  payment  received by the Lender under this Section  2.9(b) may
                  be applied to the Borrower indebtedness,  in such order and in
                  such amounts as the Lender,  in its discretion,  may from time
                  to time determine.
                                      A-8


         (c)      The Borrower  shall give prior written notice to Lender before
                  a proposed  borrowing (a "Borrowing")  pursuant to Section 2.3
                  hereof.  Such notice  shall be  irrevocable  and shall in each
                  case refer to this  Agreement.  Each notice of Borrowing shall
                  be deemed a  representation  by Borrower  that all  conditions
                  precedent to such Borrowing have been satisfied.

         j. Additional  Costs. If either (i) any change in any law or regulation
(or its  interpretation),  or (ii) the compliance  with any guideline or request
from any central lender or other  governmental  authority (whether or not having
the force of law),  affects or would  affect the amount of capital  required  or
expected  to be  maintained  by the Lender or any  corporation  controlling  the
Lender and the Lender determines that the amount of such capital is increased by
or based upon the  existence  of the Loan (or  commitment  to make the Loan) and
other  extensions of credit (or  commitments  to extend credit) of similar type,
then, upon demand by the Lender,  the Borrower shall pay to the Lender from time
to time as specified by the Lender additional  amounts  sufficient to compensate
the Lender in the light of such  circumstances,  to the  extent  that the Lender
reasonably  determines such increase in capital to be allocable to the existence
of the Lender's  Loan (or  commitment to make the Loan).  A  certificate  of the
Lender  submitted  to the Borrower as to such amounts  shall be  conclusive  and
binding for all purposes,  absent manifest error.  Upon notice from the Borrower
to the Lender  within  five (5)  Business  Days after the  Lender  notifies  the
Borrower  of any such  additional  costs  pursuant  to this  Section  2.10,  the
Borrower  may either (A) prepay in full the Loan if so affected,  together  with
interest accrued thereon to the date of such prepayment, or (B) convert the Loan
if so affected  into a Loan of any other type not so affected upon not less than
four (4) Business Days' notice to the Lender.

k.       Payments.

         (a)      The Borrower shall make each payment  (including  principal of
                  or interest  on any  Borrowing  or any Fees or other  amounts)
                  hereunder  and under any other  Loan  Document  not later than
                  12:00 (noon),  Denver,  Colorado time, on the date when due in
                  dollars to the Lender at its offices at 1675  Broadway,  Suite
                  500, Denver, Colorado 80202, in immediately available funds.

         (b)      Whenever  any payment  (including  principal of or interest on
                  any Borrowing or any Fees or other amounts) hereunder or under
                  any other Loan Document  shall become due, or otherwise  would
                  occur,  on a day that is not a Business  Day, such payment may
                  be  made  on  the  next  succeeding  Business  Day,  and  such
                  extension  of time  shall  in such  case  be  included  in the
                  computation of interest or Fees, if applicable.

                  title that do not  interfere  with its  ability to conduct its
                  business as currently  conducted or to utilize such properties
                  and  assets for their  intended  purposes.  As of the  Closing
                  Date,  all  of  Borrower's   material  properties  and  assets

                  Borrower, threatened against the Borrower or any Subsidiary or
                  any business,  property or rights of any such person (i) which
                  involve any Loan  Document or the  Transactions  or (ii) as to
                  which  there  is  a  reasonable   possibility  of  an  adverse
                  determination  and  which,  if  adversely  determined,  could,
                  individually or in the aggregate, result in a Material Adverse

                  could result in a Material Adverse Change.

         (b)      Neither the Borrower nor any of its Subsidiaries is in default

                  material  agreement or instrument to which it is a party or by
                  which  it or any of its  properties  or  assets  are or may be
                  bound,  where such default could result in a Material  Adverse
                  Change.

                  extend  credit to others  for the  purpose  of  purchasing  or
                  carrying  Margin  Stock or to refund  indebtedness  originally
                  incurred  for  such  purpose,  or (ii) for any  purpose  which
                  entails a violation  of, or which is  inconsistent  with,  the
                  provisions  of  the   Regulations  of  the  Board,   including
                  Regulation G, U or X.

material  misstatement  of fact or  omitted,  omits or will  omit to  state  any
material  fact  necessary to make the  statements  therein,  in the light of the
circumstances under which they were, are or will be made, not misleading.

Affiliates  is in  compliance  in all  material  respects  with  the  applicable
provisions  of  ERISA  and  the   regulations   and  published   interpretations
thereunder.  No  Reportable  Event has  occurred as to which the Borrower or any
ERISA  Affiliate  was  required to file a report with the PBGC,  and the present
value of all benefit  liabilities  under each Plan  (based on those  assumptions
used to fund such Plan) did not, as of the last annual valuation date applicable
thereto, exceed by a material amount the value of the assets of such Plan.

         p. Operation of Business. The Borrower possesses all licenses, permits,
franchises, patents, copyrights, trademarks, and trade names, or rights thereto,
to conduct  its  effective  businesses  substantially  as now  conducted  and as

rules and regulations promulgated thereunder (including without limitation those
relating to the  environment,  health and safety) . The Borrower has been issued
and will maintain all required  federal,  state,  and local  permits,  licenses,
certificates,  and approvals  relating to (1) air  emissions;  (2) discharges to
surface water or  groundwater;  (3) noise  emissions;  (4) solid or liquid waste

d.       Expenses; Indemnity.

         i. The Borrower agrees to pay all  out-of-pocket  expenses  incurred by
the Lender in connection  with the  preparation  of this Agreement and the other
Loan Documents or in connection with any amendments, modifications or waivers of
the  provisions  hereof  or  thereof  (whether  or not the  transactions  hereby

other  indebtedness  at any time  owing by  Lender  to or for the  credit or the
account of the Borrower  against any of and all the  obligations of the Borrower
now or hereafter  existing under this Agreement and other Loan Documents held by
Lender,  irrespective  of whether or not Lender shall have made any demand under
this Agreement or such other Loan Document and although such  obligations may be

hereunder  shall  operate as a waiver  thereof,  nor shall any single or partial
exercise of any such right or power,  or any  abandonment or  discontinuance  of
steps to enforce such a right or power,  preclude any other or further  exercise
thereof or the exercise of any other right or power.  The rights and remedies of
Lender hereunder and under the other Loan Documents are cumulative and exclusive
of any rights or  remedies  which they would  otherwise  have.  No waiver of any
provision  of this  Agreement  or any other  Loan  Document  or  consent  to any
departure by the Borrower  therefrom shall in any event be effective  unless the
same shall be permitted by paragraph (b) below,  and then such waiver or consent
shall be effective  only in the specific  instance and for the purpose for which
given.

                                      A-19


No notice or demand on the  Borrower in any case shall  entitle the  Borrower to
any other or further  notice or demand in similar or other  circumstances.  Each
holder of any of the Notes shall be bound by any amendment, modification, waiver
or consent  authorized as provided  herein,  whether or not such Note shall have
been marked to indicate such amendment, modification, waiver or consent.

         ii.  Neither this  Agreement  nor any  provision  hereof may be waived,
amended or modified  except  pursuant to an agreement or  agreements  in writing
entered into by the Borrower and the Lender.

         h. Interest Rate Limitation.  Notwithstanding anything herein or in the
Notes to the contrary,  if at any time the applicable  interest  rate,  together
with all fees and charges  which are treated as interest  under  applicable  law
(collectively  the  "Charges"),  as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by Lender,  shall exceed the maximum lawful rate (the "Maximum
Rate") which may be  contracted  for,  charged,  taken,  received or reserved by
Lender in accordance with applicable law, the rate of interest payable under the
Note,  together  with all  Charges  payable to  Lender,  shall be limited to the
Maximum Rate.

         i.  Entire  Agreement.  This  Agreement  and the other  Loan  Documents
constitute  the entire  contract  between  the  parties  relative to the subject
matter  hereof.  Any  previous  agreement  among the parties with respect to the
subject  matter  hereof is  superseded  by this  Agreement  and the  other  Loan
Documents.  Nothing in this Agreement or in the other Loan Documents,  expressed
or implied,  is intended to confer upon any party other than the parties  hereto
any rights,  remedies,  obligations  or  liabilities  under or by reason of this
Agreement or the other Loan Documents.

         j.  Waiver of Jury  Trial.  Each party  hereto  hereby  waives,  to the
fullest extent  permitted by applicable law, any right it may have to a trial by
jury in respect of any litigation  directly or indirectly  arising out of, under
or in connection  with this Agreement or any of the other Loan  Documents.  Each
party  hereto (a)  certifies  that no  representative,  agent or attorney of any
other party has represented, expressly or otherwise, that such other party would
not, in the event of  litigation,  seek to enforce the foregoing  waiver and (b)
acknowledges  that it and the other  parties  hereto have been  induced to enter
into this Agreement and the other Loan Documents, as applicable, by, among other
things, the mutual waivers and certifications in this Section 8.11.

k.  Severability. In the event any one or more of the provisions
contained in this Agreement or in any other Loan Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby. The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

         l.  Counterparts.  This  Agreement  may be  executed  in  two  or  more
counterparts,  each of which shall  constitute an original but all of which when
taken together shall constitute but one contract,  and shall become effective as
provided in Section 8.3.

         m.  Headings.  Article and Section  headings  and the Table of Contents
used  herein  are for  convenience  of  reference  only,  are  not  part of this
Agreement  and are not to  affect  the  construction  of,  or to be  taken  into
consideration in interpreting, this Agreement.

         Jurisdiction; Consent to Service of Process.

         i. The Borrower hereby  irrevocably and  unconditionally  submits,  for
itself and its property, to the nonexclusive  jurisdiction of any Colorado State
court or  Federal  court of the  United  States of  America  sitting  in Denver,
Colorado,  and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement or the other Loan Documents, or for
recognition  or  enforcement  of any  judgment,  and each of the parties  hereto
hereby irrevocably and unconditionally  agrees that all claims in respect of any
such action or proceeding may be heard and determined in such Colorado State or,
to the extent  permitted  by law,  in such  Federal  court.  Each of the parties
hereto agrees that a final  judgment in any such action or  proceeding  shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.  Nothing in this Agreement shall affect any
right that Lender may otherwise have to bring any action or proceeding  relating
to this  Agreement  or the other Loan  Documents  against  the  Borrower  or its
properties in the courts of any jurisdiction.

         ii. The Borrower hereby irrevocably and unconditionally  waives, to the
fullest extent it may legally and  effectively do so, any objection which it may
now or hereafter  have to the laying of venue of any suit,  action or proceeding
arising out of or relating to this  agreement or the other Loan Documents in any
Colorado State or Federal court.  Each of the parties hereto hereby  irrevocably
waives,  to the fullest extent  permitted by law, the defense or an inconvenient
forum to the maintenance of such action or proceeding in any such court.



                                      A-20


         iii. Each party to this  Agreement  irrevocably  consents to service of
process in the manner  provided  for  notices  in Section  8.1.  Nothing in this
Agreement  will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         IN WITNESS  WHEREOF,  the  Borrower  and the Lender  have  caused  this
Agreement to be duly executed by their respective  authorized officers as of the
day and year first above written.
