Warrant Purchase Agreement and each promissory note, contract, instrument and
other document required hereby or at any time hereafter delivered to Lender in
connection herewith (collectively, the "LOAN DOCUMENTS") have been duly

provisions hereof will constitute legal, valid and binding agreements and
obligations of Borrower, enforceable in accordance with their respective terms.

SECTION 2.03 NO VIOLATION. The execution, delivery and performance by Borrower
of each of the Loan Documents do not violate any provision of any law or
regulation, or contravene any provision of the Articles of Incorporation or
By-Laws of Borrower, or result in any breach of or default under any contract,
obligation, indenture or other instrument to which Borrower is a party or by
which Borrower may be bound.

SECTION 2.04 LITIGATION. There are no pending, or to the best of Borrower's

writing prior to the date hereof.

SECTION 2.05 CORRECTNESS OF FINANCIAL STATEMENT. The pro forma financial
statement of Borrower has been prepared by the chief financial officer of
Borrower after doing the required due diligence for Borrower to represent and
warrant herein that such statement is complete and correct and presents fairly
the financial condition and projections of Borrower for the period therein
stated. The balance sheet of Borrower dated February 6, 2001, a true copy of
which has been delivered by Borrower to Lender prior to the date hereof, (a) is
complete and correct and presents fairly the financial condition of Borrower,
(b) discloses all liabilities of Borrower that are required to be reflected or
reserved against under generally accepted accounting principles, whether
liquidated or unliquidated, fixed or contingent, and (c) has been prepared in
accordance with generally accepted accounting principles consistently applied.
Since the date of such balance sheet there has been no material adverse change

properties except in favor of Lender or as otherwise permitted by Lender in
writing.

requires the subordination in right of payment of any of Borrower's obligations
subject to this Agreement to any other obligation of Borrower except as provided
in the Subordination Agreement and Intercreditor Agreement.

SECTION 2.08 PERMITS, FRANCHISES. Borrower possesses, and will hereafter

ERISA with respect to each Plan; and each Plan will be able to fulfill its
benefit obligations as they come due in accordance with the Plan documents and
under generally accepted accounting principles.

SECTION 2.11 ENVIRONMENTAL MATTERS. Except as disclosed by Borrower to Lender in
writing prior to the date hereof, Borrower is in compliance, which compliance

environmental, hazardous waste, health and safety statutes, and any rules or
regulations adopted pursuant thereto, which govern or affect any of Borrower's
operations and/or properties, including without limitation, the Comprehensive

SECTION 2.13 NO CONSENT. The Borrower's execution, delivery and performance of

or governmental body of the United States of America or any state thereof or any
political subdivision of the United States of America or any state thereof.

SECTION 2.14 QUALIFIED COMMERCIAL LOAN. This loan is a Qualified Commercial Loan

                                EVENTS OF DEFAULT
                                -----------------

         SECTION 6.01 EVENTS OF DEFAULT. The occurrence of any of the following

or other amounts payable under any of the Loan Documents.

         (b) Any financial statement or certificate furnished to Lender in

by its nature can be cured, such default shall continue for a period of twenty
(20) days from its occurrence.

         (d) Any default in the payment or performance of any obligation, or any
defined event of default, under the terms of any contract or instrument (other
than any of the Loan Documents) pursuant to which Borrower or any guarantor
hereunder has incurred any debt or other liability to any person or entity,
including Lender.

         (e) The filing of a notice of judgment lien against Borrower or any
guarantor hereunder; or the recording of any abstract of judgment against

and/or of a writ of attachment or execution, or other like process, against the
assets of Borrower or any guarantor hereunder; or the entry of a judgment
against Borrower or any guarantor hereunder. Notwithstanding the foregoing,
there shall not be an Event of Default upon the filing of notices of judgment
lien, the recording of abstracts of judgment, or the entries of judgment against
Borrower or any guarantor hereunder if the aggregate amount of all such
judgments is less than $50,000 and such judgments are released within sixty (60)
days of the filing, recording or entry of such judgment.

         (f) Borrower or any guarantor hereunder shall become insolvent, or
shall suffer or consent to or apply for the appointment of a receiver, trustee,
custodian or liquidator of itself or any of its property, or shall generally
fail to pay its debts as they become due, or shall make a general assignment for
the benefit of creditors; Borrower or any guarantor hereunder shall file a
voluntary petition in bankruptcy, or seeking reorganization, in order to effect
a plan or other arrangement with creditors or any other relief under the

law granting relief to debtors, whether now or hereafter in effect; or any
involuntary petition or proceeding pursuant to the Bankruptcy Code or any other

                                      -9-
<PAGE>

applicable state or federal law relating to bankruptcy, reorganization or other
relief for debtors is filed or commenced against Borrower or any guarantor
hereunder, or Borrower or any such guarantor shall file an answer admitting the
jurisdiction of the court and the material allegations of any involuntary
petition; or Borrower or any such guarantor shall be adjudicated a bankrupt, or
an order for relief shall be entered against Borrower or any such guarantor by
any court of competent jurisdiction under the Bankruptcy Code or any other
applicable state or federal law relating to bankruptcy, reorganization or other
relief for debtors.

         (g) There shall exist or occur any event or condition which Lender in
good faith believes impairs, or is substantially likely to impair, the prospect
of payment or performance by Borrower of its obligations under any of the Loan
Documents.

         (h) The dissolution or liquidation of Borrower; or Borrower, or any of
its directors or stockholders, shall take action seeking to effect the
dissolution or liquidation of Borrower.

         (i) Any change in ownership during the term of this Agreement of an
aggregate of twenty-five percent (25%) or more of the common stock of
stockholders' equity in Borrower.

         (j) Any "EVENT OF DEFAULT" as defined under the WF Bank Loan Documents,
the WF Finance Loan Documents or Seller's Note or any amendments, modifications
or restatements thereof.

SECTION 6.02 REMEDIES. Upon (a) the occurrence of any Event of Default under
SUBSECTION 6.1(F) above, all Indebtedness including principal and accrued and
unpaid interest outstanding under each of the Loan Documents shall become
automatically due and payable and (b) upon the occurrence of any other Event of
Default, all Indebtedness including all principal and accrued and unpaid
interest outstanding under each of the Loan Documents, any term thereof to the
contrary notwithstanding, shall at Lender's option and without notice become
immediately due and payable; in each case without presentment, demand, or any
notices of any kind, including without limitation notice of nonperformance,
notice of protest, protest, notice of dishonor, notice of intention to
accelerate or notice of acceleration, all of which are hereby expressly waived
by each Borrower. Upon acceleration of the Indebtedness, Lender shall have all
rights, powers and remedies available under each of the Loan Documents, or
accorded by law, including without limitation the right to resort to any or all
security for any credit subject hereto and to exercise any or all of the rights
of a beneficiary or secured party pursuant to applicable law. All rights, powers
and remedies of Lender may be exercised at any time by Lender and from time to
time after the occurrence of an Event of Default, are cumulative and not
exclusive, and shall be in addition to any other rights, powers or remedies
provided by law or equity.

                                  ARTICLE VII.
                                  MISCELLANEOUS
                                  -------------

SECTION 7.01 NO WAIVER. No delay, failure or discontinuance of Lender in
exercising any right, power or remedy under any of the Loan Documents shall
affect or operate as a waiver of such right, power or remedy; nor shall any
single or partial exercise of any such right, power or remedy preclude, waive or
otherwise affect any other or further exercise thereof or the exercise of any
other right, power or remedy. Any waiver, permit, consent or approval of any
kind by Lender of any breach of or default under any of the Loan Documents must
be in writing and shall be effective only to the extent set forth in such
writing.

SECTION 7.02 NOTICES. All notices, requests and demands which any party is
required or may desire to give to any other party under any provision of this
Agreement must be in writing delivered to each party at the following address:

person) relating to any Borrower or any other person or entity, (d) the
performance, prior to the date hereof and after any Event of Default, of an

of this Agreement; provided, however, Lender shall coordinate with WF Bank on
performing such collateral audits and Borrower's out-of-pocket cost and expense
under this SUBSECTION (E) shall be limited to $3,500 per collateral audit.

SECTION 7.04 SUCCESSORS, ASSIGNMENT. This Agreement shall be binding upon and
inure to the benefit of the heirs, executors, administrators, legal
representatives, successors and assigns of the parties; provided however, that
Borrower may not assign or transfer its interest hereunder without Lender's
prior written consent. Lender reserves the right to sell, assign, transfer,
negotiate or grant participations in all or any part of, or any interest in,
Lender's rights and benefits under each of the Loan Documents. In connection

has or may hereafter acquire relating to any credit subject hereto, Borrower or

collateral required hereunder.

SECTION 7.05 AMENDMENT. This Agreement may be amended or modified only in
writing signed by each party hereto.

SECTION 7.06 NO THIRD PARTY BENEFICIARIES. This Agreement is made and entered

                                      -11-
<PAGE>

SECTION 7.07 TIME. Time is of the essence of each and every provision of this
Agreement and each other of the Loan Documents.

SECTION 7.08 SEVERABILITY OF PROVISIONS. If any provision of this Agreement
shall be prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity without
invalidating the remainder of such provision or any remaining provisions of this
Agreement.

SECTION 7.09 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which when executed and delivered shall be deemed to be an
original, and all of which when taken together shall constitute one and the same
Agreement.

SECTION 7.10 GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Texas.

SECTION 7.11 SAVINGS CLAUSE. It is the intention of the parties to comply
strictly with applicable usury laws. Accordingly, notwithstanding any provision
to the contrary in the Loan Documents, in no event shall any Loan Documents
require the payment or permit the payment, taking, reserving, receiving,
collection or charging of any sums constituting interest under applicable laws
that exceed the maximum amount permitted by such laws, as the same may be
amended or modified from time to time (the "MAXIMUM RATE"). If any such excess
interest is called for, contracted for, charged, taken, reserved or received in
connection with any Loan Documents, or in any communication by or any other
person to Borrower or any other person, or in the event that all or part of the
principal or interest hereof or thereof shall be prepaid or accelerated, so that
under any of such circumstances or under any other circumstance whatsoever the
amount of interest contracted for, charged, taken, reserved or received on the
amount of principal actually outstanding from time to time under the Loan
Documents shall exceed the Maximum Rate, then in such event it is agreed that:
(i) the provisions of this Paragraph shall govern and control; (ii) neither
Borrower nor any other person or entity now or hereafter liable for the payment
of any Loan Documents shall be obligated to pay the amount of such interest to
the extent it is in excess of the Maximum Rate; (iii) any such excess interest
which is or has been received by Lender, notwithstanding this paragraph, shall
be credited against the then unpaid principal balance hereof or thereof, or if
any of the Loan Documents has been or would be paid in full by such credit,
refunded to Borrower; and (iv) the provisions of each of the Loan Documents, and
any other communication to Borrower, shall immediately be deemed reformed and
such excess interest reduced, without the necessity of executing any other
document, to the Maximum Rate. The right to accelerate the maturity of the Loan
Documents does not include the right to accelerate, collect or charge unearned
interest, but only such interest that has otherwise accrued as of the date of
acceleration. Without limiting the foregoing, all calculations of the rate of
interest contracted for, charged, taken, reserved or received in connection with
any of the Loan Documents which are made for the purpose of determining whether
such rate exceeds the Maximum Rate shall be made to the extent permitted by
applicable laws by amortizing, prorating, allocating and spreading during the
period of the full term of such Loan Documents, including all prior and
subsequent renewals and extensions hereof or thereof, all interest at any time
contracted for, charged, taken, reserved or received by Lender. The terms of
this Paragraph shall be deemed to be incorporated into each of the other Loan
Documents.

         To the extent that either Chapter 303 or 306, or both, of the Texas
Finance Code apply in determining the Maximum Rate, Lender hereby elects to
determine the applicable rate ceiling by using the weekly ceiling from time to
time in effect, subject to Lender's right subsequently to change such method in
accordance with applicable law, as the same may be amended or modified from time
to time.

                                      -12-

SECTION 7.12 RIGHT OF SETOFF; DEPOSIT ACCOUNTS. Upon and after the occurrence of
an Event of Default, (a) Borrower hereby authorizes Lender and WF Bank, acting
on Lender's behalf, at any time and from time to time, without notice, which is
hereby expressly waived by each Borrower, and whether or not Lender shall have
declared any credit subject hereto to be due and payable in accordance with the
terms hereof, to set off against, and to appropriate and apply to the payment
of, Borrower's obligations and liabilities under the Loan Documents (whether
matured or unmatured, fixed or contingent, liquidated or unliquidated), any and
all amounts owing by Lender to Borrower (whether payable in U.S. dollars or any
other currency, whether matured or unmatured, and in the case of deposits,
whether general or special (except trust and escrow accounts), time or demand
and however evidenced), and (b) pending any such action, to the extent
necessary, to hold such amounts as collateral to secure such obligations and
liabilities and to return as unpaid for insufficient funds any and all checks
and other items drawn against any deposits so held as Lender, in its sole
discretion, may elect. Borrower hereby grants to Lender a security interest in
all deposits and accounts maintained with Lender and with any other financial
institution to secure the payment of all obligations and liabilities of Borrower
to Lender under the Loan Documents subject only to prior liens and security
interests in favor of WF Bank.

SECTION 7.13 BUSINESS PURPOSE. Borrower represents and warrants that each credit
subject hereto is for a business, commercial, investment, agricultural or other
similar purpose and not primarily for a personal, family or household use.

SECTION 7.14 ARBITRATION.

         (a) ARBITRATION. The parties hereto agree, upon demand by any party, to
submit to binding arbitration all claims, disputes and controversies between or
among them (and their respective employees, officers, directors, attorneys, and
other agents), whether in tort, contract or otherwise arising out of or relating
to in any way (i) the loan and related Loan Documents which are the subject of
this Agreement and its negotiation, execution, collateralization,
administration, repayment, modification, extension, substitution, formation,
inducement, enforcement, default or termination; or (ii) requests for additional
credit.

         (b) GOVERNING RULES. Any arbitration proceeding will (i) proceed in a
location in Texas selected by the American Arbitration Association ("AAA"); (ii)
be governed by the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in any of the documents
between the parties; and (iii) be conducted by the AAA, or such other
administrator as the parties shall mutually agree upon, in accordance with the
AAA's commercial dispute resolution procedures, unless the claim or counterclaim
is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and
costs in which case the arbitration shall be conducted in accordance with the
AAA's optional procedures for large, complex commercial disputes (the commercial
dispute resolution procedures or the optional procedures for large, complex
commercial disputes to be referred to, as applicable, as the "RULES"). If there
is any inconsistency between the terms hereof and the Rules, the terms and
procedures set forth herein shall control. Any party who fails or refuses to
submit to arbitration following a demand by any other party shall bear all costs
and expenses incurred by such other party in compelling arbitration of any
dispute. Nothing contained herein shall be deemed to be a waiver by any party
that is a Lender of the protections afforded to it under 12 U.S.C. ss.91 or any
similar applicable state law.

                                      -13-
<PAGE>

         (c) NO WAIVER OF PROVISIONAL REMEDIES, SELF-HELP AND FORECLOSURE. The
arbitration requirement does not limit the right of any party to (i) foreclose
against real or personal property collateral; (ii) exercise self-help remedies
relating to collateral or proceeds of collateral such as setoff or repossession;
or (iii) obtain provisional or ancillary remedies such as replevin, injunctive
relief, attachment or the appointment of a receiver, before during or after the
pendency of any arbitration proceeding. This exclusion does not constitute a
waiver of the right or obligation of any party to submit any dispute to
arbitration or reference hereunder, including those arising from the exercise of
the actions detailed in Sections (i), (ii) and (iii) of this paragraph.

         (d) ARBITRATOR QUALIFICATIONS AND POWERS. Any arbitration proceeding in
which the amount in controversy is $5,000,000.00 or less will be decided by a
single arbitrator selected according to the Rules, and who shall not render an
award of greater than $5,000,000.00. Any dispute in which the amount in
controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel
of three arbitrators; provided however, that all three arbitrators must actively
participate in all hearings and deliberations. The arbitrator will be a neutral
attorney licensed in the State of Texas with a minimum of ten years experience
in the substantive law applicable to the subject matter of the dispute to be
arbitrated. The arbitrator will determine whether or not an issue is
arbitratable and will give effect to the statutes of limitation in determining
any claim. In any arbitration proceeding the arbitrator will decide (by
documents only or with a hearing at the arbitrator's discretion) any pre-hearing
motions which are similar to motions to dismiss for failure to state a claim or
motions for summary adjudication. The arbitrator shall resolve all disputes in
accordance with the substantive law of Texas and may grant any remedy or relief
that a court of such state could order or grant within the scope hereof and such
ancillary relief as is necessary to make effective any award. The arbitrator
shall also have the power to award recovery of all costs and fees, to impose
sanctions and to take such other action as the arbitrator deems necessary to the
same extent a judge could pursuant to the Federal Rules of Civil Procedure, the
Texas Rules of Civil Procedure or other applicable law. Judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction. The
institution and maintenance of an action for judicial relief or pursuit of a
provisional or ancillary remedy shall not constitute a waiver of the right of
any party, including the plaintiff, to submit the controversy or claim to
arbitration if any other party contests such action for judicial relief.

         (e) DISCOVERY. In any arbitration proceeding discovery will be
permitted in accordance with the Rules. All discovery shall be expressly limited
to matters directly relevant to the dispute being arbitrated and must be
completed no later than 20 days before the hearing date and within 180 days of
the filing of the dispute with the AAA. Any requests for an extension of the
discovery periods, or any discovery disputes, will be subject to final
determination by the arbitrator upon a showing that the request for discovery is
essential for the party's presentation and that no alternative means for
obtaining information is available.

         (f) CLASS PROCEEDINGS AND CONSOLIDATIONS. The resolution of any dispute
arising pursuant to the terms of this Agreement shall be determined by a
separate arbitration proceeding and such dispute shall not be consolidated with
other disputes or included in any class proceeding.

         (g) PAYMENT OF ARBITRATION COSTS AND FEES. The arbitrator shall award
all costs and expenses of the arbitration proceeding.

         (h) MISCELLANEOUS. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business or by applicable law or
regulation. If more than one agreement for arbitration by or between the parties
potentially applies to a dispute, the arbitration provision most directly
related to the Loan Documents or the subject matter of the dispute shall
control. This arbitration provision shall survive termination, amendment or
expiration of any of the Loan Documents or any relationship between the parties.

                                      -14-

SECTION 7.15 INDEMNIFICATION. Borrower agrees to indemnify Lender, each assignee

directors, employees, representatives, agents, attorneys, accountants and
experts ("INDEMNIFIED PARTIES") from, hold each of them harmless against and
promptly upon demand pay or reimburse each of them for, the Indemnity Matters
(hereafter defined) which may be incurred by or asserted against or involve any
of them (whether or not any of them is designated a party thereto) as a result
of, arising out of or in any way related to (i) any actual or proposed use by
Borrower of the proceeds of any of the Loans, (ii) the execution, delivery and
performance of the Loan Documents, (iii) the operations of the business of
Borrower, (iv) the failure of Borrower to comply with the terms of any Loan
Document or this Agreement, or with any applicable law, (v) any inaccuracy of
any representation or any breach of any warranty of Borrower set forth in any of
the Loan Documents, (vi) any assertion that any Indemnified Party was not
entitled to receive the proceeds received pursuant to the Loan Documents or
(vii) any other aspect of the Loan Documents, including, without limitation, the
reasonable fees and disbursements of counsel and all other expenses incurred in
connection with investigating, defending or preparing to defend any such action,
suit, proceeding (including any investigations, litigation or inquiries) or
claim and including all Indemnity Matters arising by reason of the ordinary
negligence of any Indemnified Party, but excluding all Indemnity Matters arising
solely by reason of claims between the Lender or any assignee or participant, or
any such party's shareholders against Lender or any assignee or participant or
by reason of the gross negligence or willful misconduct on the part of the
Indemnified Party. "INDEMNITY MATTERS" shall mean any and all actions, suits,
proceedings (including any investigations, litigation or inquiries), claims,
demands and causes of action made or threatened against a person and, in
connection therewith, all losses, liabilities, damages (including, without
limitation, consequential damages) or reasonable costs and expenses of any kind
or nature whatsoever incurred by such person whether caused by the sole or
concurrent negligence of such person seeking indemnification.

SECTION 7.16 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, BORROWER HEREBY IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A TRIAL BY
JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT,
TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE
LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF LENDER
IN THE NEGOTIATION, ADMINISTRATION OR ENFORCEMENT THEREOF.

THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES RELATING TO THE INDEBTEDNESS.

                                    ---------

2,000,000.00                                                      Houston, Texas
                                                                February 6, 2001

         FOR VALUE RECEIVED, the undersigned MOUNTAIN COMPRESSED AIR, INC., a
Texas corporation ("BORROWER"), promises to pay to the order of WELLS FARGO
ENERGY CAPITAL, INC., Texas corporation ("LENDER") at its office at 1000
Louisiana, Suite 600, Houston, Texas 77002, or at such other place as the holder
hereof may designate, in lawful money of the United States of America and in
immediately available funds, the principal sum of Two Million Dollars
($2,000,000.00), with interest thereon as set forth herein. This Note is issued
in connection with that certain Credit Agreement between Lender and Borrower of
even date herewith (the "CREDIT AGREEMENT"), and is secured as provided therein
by the Security Documents. All capitalized terms not otherwise defined herein
are defined in the Credit Agreement.

INTEREST:

         (a) INTEREST. Borrower agrees to pay interest at Lender's address
listed above on the unpaid principal note hereof and, to the extent permitted by
law, the accrued interest in respect hereof from time to time from the date
hereof until payment in full of the principal amount hereof and accrued interest
hereon, at a rate equal to twelve percent (12%) per annum. Interest shall be
computed on the basis of a 360-day year, actual days elapsed, unless such
calculation would result in a usurious rate, in which case interest shall be
computed on the basis of a 365/366-day year, as the case may be, actual days
elapsed. Interest shall be payable quarterly commencing on April 1, 2001, and
continuing on the first day of each succeeding third month thereof until
"MATURITY" as hereinbelow defined.

         (b) DEFAULT INTEREST. From and after the maturity date of this Note, or
such earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed, unless such calculation would
result in a usurious rate, in which case interest shall be computed on the basis
of a 365/366-day year, as the case may be, actual days elapsed) equal to
fourteen percent (14%) per annum, but in no event at a rate greater than the
Maximum Rate.

REPAYMENT AND PREPAYMENT:

         (a) REPAYMENT. Principal shall be payable upon maturity hereof, January
31, 2004 ("MATURITY") or such sooner date if principal under this Note is
accelerated as provided herein.

         (b) APPLICATION OF PAYMENTS. Each payment made on this Note shall be
credited first, to any interest then due and second, to the outstanding
principal balance hereof.

<PAGE>

         (c) PREPAYMENT. Borrower may prepay this Note provided that all terms
in the Credit Agreement and herein are complied with (including the payment of
any prepayment penalties required in the Credit Agreement), at any time upon one
day prior notice and in the minimum amount of One Hundred Thousand Dollars
($100,000); PROVIDED, HOWEVER, that if the outstanding principal balance of such
portion of this Note is less than said amount, the minimum prepayment amount
shall be the entire outstanding principal hereof.

EVENTS OF DEFAULT:

         (a) EVENTS OF DEFAULT. The occurrence of an Event of Default under the
Credit Agreement shall constitute an "Event of Default" under this Note.

         (b) REMEDIES. Upon (i) the occurrence of any Event of Default under
SUBSECTION 6.1 (F), all sums of principal and accrued and unpaid interest
outstanding hereunder shall become automatically due and payable and (ii) upon
the occurrence of any other Event of Default, the holder of this Note, at the
holder's option, may declare all sums of principal and accrued and unpaid
interest outstanding hereunder to be immediately due and payable; in each case
without presentment, demand, or any notices of any kind, including without
limitation notice of nonperformance, notice of protest, protest, notice of
dishonor, notice of intention to accelerate or notice of acceleration, all of
which are expressly waived by Borrower, and the obligation, if any, of the
holder to extend any further credit hereunder shall immediately cease and
terminate. Borrower shall pay to the holder immediately upon demand the full
amount of all payments, advances, charges, costs and expenses, including
reasonable attorneys' fees (to include outside counsel fees and all allocated
costs of the holder's in-house counsel to the extent permissible), expended or
incurred by the holder in connection with the enforcement of the holder's rights
and/or the collection of any amounts which become due to the holder under this
Note, and the prosecution or defense of any action in any way related to this
Note, including without limitation, any action for declaratory relief, whether
incurred at the trial or appellate level, in an arbitration proceeding or
otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Lender or any other person) relating to
any Borrower or any other person or entity.

         MISCELLANEOUS:

         (a) GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS. THIS NOTE IS PERFORMABLE IN
HARRIS COUNTY, TEXAS. ANY ACTION OR PROCEEDING UNDER OR IN CONNECTION WITH THIS
NOTE AGAINST BORROWER OR ANY THIRD PARTY OBLIGOR MAY BE BROUGHT IN ANY STATE OR
FEDERAL COURT IN HARRIS COUNTY, TEXAS. BORROWER AND EACH THIRD PARTY OBLIGOR
HEREBY IRREVOCABLY (I) SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS,
AND (II) WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF
ANY SUCH ACTION OR PROCEEDING BROUGHT IN SUCH COURT OR THAT SUCH COURT IS AN
INCONVENIENT FORUM. NOTHING HEREIN SHALL AFFECT THE RIGHT OF LENDER TO BRING ANY
ACTION OR PROCEEDING AGAINST BORROWER OR ANY THIRD PARTY OBLIGOR OR WITH RESPECT

                                      A-2

         (b) SAVINGS CLAUSE. It is the intention of the parties to comply
strictly with applicable usury laws. Accordingly, notwithstanding any provision
to the contrary in this Note, the Credit Agreement, or in any contract,
instrument or document evidencing or securing the payment hereof or otherwise
relating hereto (each, a "RELATED DOCUMENT"), in no event shall this Note or any
Related Document require the payment or permit the payment, taking, reserving,
receiving, collection or charging of any sums constituting interest under
applicable laws that exceed the maximum amount permitted by such laws, as the
same may be amended or modified from time to time (the "MAXIMUM RATE"). If any
such excess interest is called for, contracted for, charged, taken, reserved or
received in connection with this Note or any Related Document, or in any
communication by Lender or any other person to Borrower or any other person, or
in the event that all or part of the principal or interest hereof or thereof
shall be prepaid or accelerated, so that under any of such circumstances or
under any other circumstance whatsoever the amount of interest contracted for,
charged, taken, reserved or received on the amount of principal actually
outstanding from time to time under this Note shall exceed the Maximum Rate,
then in such event it is agreed that: (i) the provisions of this paragraph shall
govern and control; (ii) neither Borrower nor any other person or entity now or
hereafter liable for the payment of this Note or any Related Document shall be
obligated to pay the amount of such interest to the extent it is in excess of
the Maximum Rate; (iii) any such excess interest which is or has been received
by Lender, notwithstanding this paragraph, shall be credited against the then
unpaid principal balance hereof or thereof, or if this Note or any Related
Document has been or would be paid in full by such credit, refunded to Borrower;
and (iv) the provisions of this Note and each Related Document, and any other
communication to Borrower, shall immediately be deemed reformed and such excess
interest reduced, without the necessity of executing any other document, to the
Maximum Rate. The right to accelerate the maturity of this Note or any Related
Document does not include the right to accelerate, collect or charge unearned
interest, but only such interest that has otherwise accrued as of the date of
acceleration. Without limiting the foregoing, all calculations of the rate of
interest contracted for, charged, taken, reserved or received in connection with
this Note and any Related Document which are made for the purpose of determining
whether such rate exceeds the Maximum Rate shall be made to the extent permitted
by applicable laws by amortizing, prorating, allocating and spreading during the
period of the full term of this Note or such Related Document, including all
prior and subsequent renewals and extensions hereof or thereof, all interest at
any time contracted for, charged, taken, reserved or received by Lender. The
terms of this paragraph shall be deemed to be incorporated into each Related
Document.

         To the extent that either Chapter 303 or 306, or both, of the Texas
Finance Code apply in determining the Maximum Rate, Lender hereby elects to
determine the applicable rate ceiling by using the weekly ceiling from time to
time in effect, subject to Lender's right subsequently to change such method in
accordance with applicable law, as the same may be amended or modified from time
to time.

         (c) RIGHT OF SETOFF; DEPOSIT ACCOUNTS. Upon and after the occurrence of
an Event of Default, (i) Borrower hereby authorizes Lender, at any time and from
time to time, without notice, which is hereby expressly waived by Borrower, and
whether or not Lender shall have declared this Note to be due and payable in
accordance with the terms hereof, to set off against, and to appropriate and
apply to the payment of, Borrower's obligations and liabilities under this Note
(whether matured or unmatured, fixed or contingent, liquidated or unliquidated),
any and all amounts owing by Lender to Borrower (whether payable in U.S. dollars

                                      A-3
<PAGE>

or any other currency, whether matured or unmatured, and in the case of
deposits, whether general or special (except trust and escrow accounts), time or
demand and however evidenced), and (ii) pending any such action, to the extent
necessary, to hold such amounts as collateral to secure such obligations and
liabilities and to return as unpaid for insufficient funds any and all checks
and other items drawn against any deposits so held as Lender, in its sole
discretion, may elect. Borrower hereby grants to Lender a security interest in
all deposits and accounts maintained with Lender and with any other financial
institution to secure the payment of all obligations and liabilities of Borrower
to Lender under this Note.

         (d) SUBORDINATION. Payment of this Note is subject to the terms of the
Subordination and Intercreditor Agreement of even date herewith between WF Bank,
Lender, WF Finance and Borrower.

NOTICE: THIS NOTE AND ALL OTHER DOCUMENTS RELATING TO THE INDEBTEDNESS EVIDENCED
HEREBY CONSTITUTE A WRITTEN LOAN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES RELATING TO THIS NOTE AND THE
INDEBTEDNESS EVIDENCED HEREBY.

         IN WITNESS WHEREOF, the undersigned has executed this Note as of the
date first written above.

                  (a) ORGANIZATION AND STANDING; CERTIFICATE AND BY-LAWS. The

          to own and operate its properties and assets, and to carry on its
          business as presently conducted and as proposed to be conducted. The
          Company is qualified to do business as a foreign corporation and is in
          good standing in all jurisdictions in which the Company owns or leases
          property or in which the failure to be so qualified would have a
          material adverse affect on the Company's business as currently
          conducted.

                  (b) CORPORATE POWER. The Company has, and will have at the

          requisite corporate power and authority to execute and deliver this
          Agreement, to sell and issue the Warrant hereunder, to issue the
          Shares upon exercise of the Warrant and to carry out and perform its

          by the Company, the authorization, sale, issuance and delivery of the
          Warrant and (upon exercise of the Warrant) the Shares and the
          performance of all of the Company's obligations hereunder and under
          the Warrant have been taken. This Agreement and the Warrant each
          constitutes a valid and binding obligation of the Company, enforceable
          in accordance with its terms, except as may be limited by insolvency,
          bankruptcy, moratorium or other laws affecting the rights of creditors
          in general. The Shares have been duly and validly reserved and, when
          issued in compliance with the provisions of this Agreement and the
          Warrant, will be validly issued, fully paid and nonassessable. Upon
          issuance upon exercise of the Warrant, the Shares will be free of any
          liens, claims or encumbrances. The Shares are not subject to any
          preemptive rights or rights of first refusal.

          any shares of its capital stock or any convertible securities, rights
          or options of the type described in the preceding sentence. The
          Company is not a party to any agreement (except as set forth in this
          Agreement) restricting the transfer of any shares of the Company's
          capital stock.

                  (e) GOVERNMENTAL CONSENT, ETC. No consent, approval or

          delivery requirements of the Securities Act of 1933 (the "Securities

                  (g) BROKERS OR FINDERS. The Company has not incurred, and will
          not incur, directly or indirectly, as a result of any action taken by
          the Company, any liability for brokerage or finders' fees or agents'

          Company were subject to the requirements of Section 13 or 15(d) of the
          Exchange Act.

persons with respect to such transaction or series of transactions is in excess
of $100,000 unless such transaction (a) is fair to the Company, (b) is not
materially adverse to the rights of the holders of Warrants, and (c) is on terms

Company and who does not beneficially own more than 5% of any outstanding class
or series of capital stock of the Company and who is not related by blood or
marriage to any of the foregoing. As used herein, "Affiliate" has the meaning
set forth in Article VII of the Warrant, except that as long as any of the
Shareholders are stockholders of the Company, such Shareholders and each of
their respective Affiliates shall be deemed Affiliates of the Company and

stockholders as such or authorize or make any other distribution, payment or
delivery of property or cash to its holders of Common Stock as such, or redeem,
retire, purchase or otherwise acquire, directly or indirectly, for a
consideration (otherwise than in exchange for, or from the proceeds of the

any shares of any class of its Common Stock now or hereafter outstanding.

                  (b) PERMITTED DIVIDENDS. The Company may pay dividends to the
holders of its Common Stock, provided that (i) contemporaneously with the
declaration of any such dividend, the Company will set aside for payment to the
holders of Warrants an amount equal to the total Dividend Amount (as hereinafter
defined) payable to all holders of Warrants and (ii) on the date of payment of
such dividend, will pay to each holder of Warrants the Dividend Amount
multiplied times the number of Warrants owned by such holder as reflected on the
Warrantholders' List. Such payment shall be made by Company check to such holder
of Warrants at the address of such Holder as reflected on the Warrantholders'

                                      B-5

List. As used herein, the Dividend Amount shall equal the dividend declared or
paid (as the case may be) with respect to one share of Common Stock multiplied
times the Dilution Factor on the date of declaration or payment.

requested by the Company and (ii) the examination will not unreasonably disrupt,
in any material manner, the operations of the Company.

         Section 5.5. RULE 144 REPORTING. The Company agrees that from and after
the date it registers any class of its securities under Section 12(b) or 12(g)
of the Exchange Act, it shall:

                  (a) Make and keep "adequate public information" available, as
          those terms are understood and defined in Rule 144 under the
          Securities Act, at all times from and after the date hereof;

                  (b) File with the Commission in a timely manner all reports
          and other documents required of the Company under the Securities Act
          and the Exchange Act; and

                  (c) So long as Purchaser owns any Shares, furnish to Purchaser
          promptly upon request a written statement by the Company as to its
          compliance with the reporting requirements (i) necessary to cause
          "adequate public information" to be available under Rule 144, and (ii)

resulting from any violation or inaccuracy of any representations, warranties,
obligations or covenants of the Company contained, disclosed or set forth in
this Agreement or the Warrant.

purchased by the Company pursuant to this Agreement, if the Company shall not be
able lawfully to purchase all of such shares on the closing date under the
provisions of applicable state corporate law dealing with impairment of surplus,
the Company shall purchase on the closing date so many of such shares as it may
lawfully purchase. In the event the Company purchases less than all of such
Shares on the closing date, then the Company shall not, without the written
consent of the Selling Holder, pay dividends, distributions or other payments to
any stockholder or make any loans to stockholders, other than reasonable salary
and benefits payments, until the remainder of such Shares are purchased in
accordance with the terms of this Agreement.

         (b) RESTRICTIONS ON CERTAIN CAPITAL TRANSACTIONS. The Company will not,
without the written consent of all holders of Warrants and Shares, increase the
par value of any Shares or effect a transfer from the retained earnings account
of the Company to the capital or additional paid in capital accounts of the
Company if, at the time of such transfer and after giving effect thereto and to
any concurrent or then contemplated transactions, the ability of the Company to
lawfully discharge its obligations to purchase shares of Shares pursuant to this
Agreement would be materially or adversely impaired.

         (c) CONTINUING OBLIGATION. If the Company is unable on the closing date
lawfully to purchase all of the Shares that it is obligated to purchase, the
obligation of the Company to purchase such Shares that the Company could not
lawfully purchase shall continue until such time as the Company may lawfully
discharge such obligation; provided, however, that the purchase price shall be
increased by an amount equal to interest on the purchase price at the rate of
__% per annum.

         Section 7.3. PURCHASE OF WARRANT. Prior to the exercise of the Warrant,
a holder of a Warrant (who shall be deemed a Selling Holder as used in Sections
7.1 and 7.2) without first exercising the Warrant, may deliver an Exercise
Notice in accordance with Section 7.1(a) as if the Warrant had been exercised
and the Shares covered by the Exercise Notice had been issued. The Selling
Holder may exercise the Warrant immediately prior to the closing date and
transfer the Shares to the Company. In lieu of exercising the Warrant, at the
closing, the Selling Holder may sell all or a portion of the Warrant to the
Company for a purchase price equal to the purchase price (computed as provided
in Section 7.1) of the Shares that could be acquired by the Selling Holder by
exercising the Warrant to be sold to the Company minus the price the Selling
Holder would be required to pay to acquire such Shares under the Warrant.
Appropriate revisions will be made to the representations and warranties to be
made by the Company and the Selling Holder as provided by Section 7.1(d) and (e)
in the event the Warrant is purchased.

         Section 7.4. COMPANY'S OPTION TO PURCHASE. From and after the

          to cause the holders of Warrants and Shares to sell all of their
          Shares and Warrants to the Company, the Company shall notify
          ("Purchase Notice") such holders ("Redeemed Holders") of its intent to
          purchase all Shares and Warrants owned by the Redeemed Holders. The
          Purchase Notice shall state: (i) the proposed closing date of such
          purchase which shall be a Business Day at least ten and no more than
          thirty Business Days from the date of such notice and (ii) the
          purchase price.

                  (b) PURCHASE PRICE. The purchase price for the aggregate
          number of Shares shall be the Put Purchase Price. The purchase price
          for the Warrant shall equal the Put Purchase Price as computed above
          minus the price for which the Shares could be acquired pursuant to
          exercise of the Warrant.

                  (c) CLOSING. The closing of any purchase pursuant to this
          Section 7.4 shall be held at the principal executive offices of the
          Company at 10:00 a.m., local time, on the date specified in the
          Purchase Notice, or such other time and place as the Company and
          Purchaser shall agree in writing. At the closing, the Company shall
          pay the Redeemed Holders the Purchase Price by cashier's check or wire
          transfer of immediately available funds. Each Redeemed Holder shall
          deliver certificates representing the securities transferred, duly
          endorsed for transfer to the Company.

                  (d) REPRESENTATIONS AND WARRANTIES. At the Closing, the
          Redeemed Holders shall make the representations and warranties
          specified in Section 7.1(d) and the Company shall make the
          representations and warranties specified in 7.1(e); provided, that
          appropriate revisions shall be made to such representations and
          warranties if Warrants are purchased by the Company.

                  (e) LEGEND. Purchaser agrees to maintain a legend on all
          Shares owned by it and on the Warrant referring to the right and
          option set forth in this Section.

                  (f) RESTRICTIONS ON PURCHASES. The Company shall not have the
          right and option to purchase Shares or Warrants as provided in this
          Section unless the Company is legally able to purchase all Shares and
          Warrants outstanding under applicable corporate law.

                  (g) NO RESTRICTION ON TRANSFER. Nothing in this Article VII
          shall restrict or limit a holder of Shares or Warrants the ability to
          sell the Warrant or Shares, except that from and after receipt of the
          Purchase Notice until the purchase of the shares as provided in this
          Section, a holder of Shares or Warrants shall not sell, assign,
          transfer or pledge the Shares.

                  (h) BREACH OF LOAN AGREEMENT OR OTHER DOCUMENTS.
          Notwithstanding any other provision herein, the Company shall not have
          the right or option to cause a holder of Shares or Warrants to sell
          Shares or Warrants to the Company if the Company has breached, is in

No. W-1                                                         February 6, 2001

Company 1,350,000 duly authorized, validly issued, fully paid and nonassessable
shares of Common Stock, $___ par value (the "Common Stock") at any time or from
time to time prior to 5:00 p.m., Houston, Texas time, on the Expiration Date (as
herein defined), all subject to terms, conditions and adjustments set forth in
this Warrant.

         This is the Warrant (the "Warrant") (such term to include any warrants
issued in substitution therefor) originally issued pursuant to the Warrant
Purchase Agreement. Certain capitalized terms used in this Warrant are defined
in Article VII; unless otherwise specified, references to an "Exhibit" mean one
of the exhibits attached to this Warrant, references to an "Article" mean one of
the articles in this Warrant and references to a "Section" mean one of the
sections of this Warrant.

                         ARTICLE I. EXERCISE OF WARRANT

         Section 1.1. MANNER OF EXERCISE. This Warrant may be exercised by the
holder hereof, in whole or in part, during normal business hours on any Business
Day, by surrender of this Warrant to the Company at its office maintained
pursuant to subdivision (a) of Section 6.2, accompanied by a subscription in
substantially the form attached to this Warrant (or a reasonable facsimile
thereof) duly executed by such holder and accompanied by payment, in cash or by
certified or official bank check payable to the order of the Company in the
amount obtained by multiplying (a) the number of shares of Common Stock (without
giving effect to any adjustment thereof) designated in such subscription by (b)
the Initial Price, and such holder shall thereupon be entitled to receive the
number of duly authorized, validly issued, fully paid and nonassessable shares
of Common Stock (or Other Securities) determined as provided in Articles II
through IV.

         Section 1.2. WHEN EXERCISE EFFECTIVE. Each exercise of this Warrant
shall be deemed to have been effected immediately prior to the close of business
on the Business Day on which this Warrant shall have been surrendered to the
Company as provided in Section 1.1, and at such time the Person or Persons in
whose name or names any certificate or certificates for shares of Common Stock
(or Other Securities) shall be issuable upon such exercise as provided in
Section 1.3 shall be deemed to have become the holder or holders of record
thereof.

                                       1
<PAGE>

         Section 1.3. DELIVERY OF STOCK CERTIFICATES, ETC. As soon as
practicable after each exercise of this Warrant, in whole or in part, and in any
event within five Business Days thereafter, the Company, at its expense
(including the payment by it of any applicable issue taxes), will cause to be
issued in the name of and delivered to the holder hereof, subject to Article V,
as such holder (upon payment by such holder of any applicable transfer taxes)
may direct, the following:

                  (a) CERTIFICATES. A certificate or certificates for the number
         of duly authorized, validly issued, fully paid and nonassessable shares
         of Common Stock (or Other Securities) to which such holder shall be
         entitled upon such exercise plus, in lieu of any fractional share to
         which such holder would otherwise be entitled, cash in an amount equal
         to the same fraction of the Market Price per share on the Business Day
         next preceding the date of such exercise.

                  (b) WARRANT. In case such exercise is in part only, a new
         Warrant or Warrants of like tenor dated the date hereof, calling in the
         aggregate on the face or faces thereof for the number of shares of
         Common Stock equal (without giving effect to any adjustment thereof) to
         the number of such shares called for on the face of this Warrant minus
         the number of such shares designated by the holder upon such exercise
         as provided in Section 1.1.

          ARTICLE II. ADJUSTMENT OF COMMON STOCK ISSUABLE UPON EXERCISE

         Section 2.1. GENERAL; WARRANT PRICE. The number of shares of Common
Stock which the holder of this Warrant shall be entitled to receive upon each
exercise hereof shall be determined by multiplying the number of shares of
Common Stock which would otherwise (but for the provisions of this Article II)
be issuable upon such exercise, as designated by the holder hereof pursuant to
Section 1.1, by a fraction (the "Dilution Factor") (a) the numerator of which is
the Initial Price and (b) the denominator of which is the Warrant Price in
effect at the effective time of such exercise (as provided in Section 1.2). The
"Warrant Price" shall initially be the Initial Price, shall be adjusted and
readjusted from time to time as provided in this Article II and, as so adjusted
or readjusted, shall remain in effect until a further adjustment or readjustment
thereof is required by this Article II.

         Section 2.2. ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. In case the
Company at any time or from time to time after the date hereof shall issue or
sell Additional Shares of Common Stock (including Additional Shares of Common
Stock deemed to be issued pursuant to section 2.4 or 2.5) without consideration
or for a consideration per share less than the Dilutive Basis, then, and in each
such case, such Warrant Price shall be reduced, concurrently with such issue or
sale, to the lower of the prices (calculated to the nearest cent) determined as
follows:

                  (a) by multiplying the Warrant Price then in existence by a
         fraction, the numerator of which shall be (i) the number of shares of
         Common Stock outstanding immediately prior to such issue or sale plus
         (ii) the number of shares of Common Stock which the aggregate
         consideration received by the Company for the total number of such
         Additional Shares of Common Stock so issued or sold would purchase at
         the Current Market Price, and the denominator of which shall be the
         number of shares of Common Stock outstanding immediately after such
         issue or sale, provided that, for the purposes of this Section 2.2, (i)
         immediately after any Additional Shares of Common Stock are deemed to
         have been issued pursuant to Section 2.4 or 2.5, such Additional Shares
         of Common Stock shall be deemed to be outstanding, and (ii) treasury
         shares shall not be deemed to be outstanding; and

                                       2
<PAGE>

                  (b) by dividing (i) an amount equal to the sum of (1) the
         number of shares of Common Stock outstanding immediately prior to such
         issuance or sale multiplied times the then effective Warrant Price plus
         (2) the total consideration, if any, received and deemed received by
         the Company upon such issue or sale, by (ii) the total number of shares
         of Common Stock outstanding and deemed outstanding immediately after
         such issue or sale.

         Section 2.3. EXTRAORDINARY DIVIDENDS AND DISTRIBUTIONS. If the Company
at any time or from time to time after the date hereof shall declare, order, pay
or make a dividend or other distribution (including, without limitation, any
distribution of other or additional stock or Other Securities or property or
Options by way of dividend or spin-off, reclassification, recapitalization or
similar corporate rearrangement) on the Common Stock, other than (a) a dividend
payable in Additional Shares of Common Stock or (b) a dividend payable in cash
or other property and declared out of the earned surplus of the Company as at
the date thereof as increased by any credits (other than credits resulting from
a revaluation of property) and decreased by any debits made thereto, then, and
in each such case, the Warrant Price in effect immediately prior to the close of
business on the record date fixed for the determination of holders of any class
of securities entitled to receive such dividend or distribution shall be
reduced, effective as of the close of business on such record date, to a price
(calculated to the nearest cent) determined by multiplying such Warrant Price by
a fraction:

                  (a) the numerator of which shall be the Current Market Price
         in effect on such record date or, if the Common Stock trades on an
         ex-dividend basis, on the date prior to the commencement of ex-dividend
         trading, less the amount of such dividend or distribution (as
         determined in good faith by the Board of Directors of the Company)
         applicable to one share of Common Stock, and

                  (b) the denominator of which shall be the Current Market Price
         on such record date, or if the Common Stock trades on an ex-dividend
         basis, on the date prior to the commencement of ex-dividend trading.

         Section 2.4. TREATMENT OF OPTIONS AND CONVERTIBLE SECURITIES. In case
the Company at any time or from time to time after the date hereof shall issue,
sell, grant or assume, or shall fix a record date for the determination of
holders of any class of securities entitled to receive, any Options or
Convertible Securities, then, and in each such case, the maximum number of
Additional Shares of Common Stock (as set forth in the instrument relating
thereto, without regard to any provisions contained therein for a subsequent
adjustment of such number) issuable upon the exercise of such Options or, in the
case of Convertible Securities and Options therefor, the conversion or exchange
of such Convertible Securities, or, in the case of Appreciation Rights, the
number computed in Section 2.9, shall be deemed to be the number of Additional
Shares of Common Stock issued as of the time of such issue, sale, grant or
assumption or, in case such a record date shall have been fixed, as of the close
of business on such record date (or, if the Common Stock trades on an
ex-dividend basis, on the date prior to the commencement of ex-dividend
trading); provided that such Additional Shares of Common Stock shall not be
deemed to have been issued unless the consideration per share (determined

                                       3
<PAGE>

pursuant to Section 2.6) of such shares would be less than the Dilutive Basis in
effect on the date of and immediately prior to such issue, sale, grant or
assumption or immediately prior to the close of business on such record date
(or, if the Common Stock trades on an ex-dividend basis, on the date prior to
the commencement of ex-dividend trading), as the case may be; and provided,
further, that in any such case in which Additional Shares of Common Stock are
deemed to be issued no further adjustment of the Warrant Price shall be made
upon the subsequent issue or sale of Convertible Securities or Additional Shares
of Common Stock upon the exercise of such Options or the conversion or exchange
of such Convertible Securities.

         Section 2.5. TREATMENT OF STOCK DIVIDENDS, STOCK SPLITS, ETC. In case
the Company at any time or from time to time after the date hereof shall declare
or pay any dividend on the Common Stock payable in Common Stock, or shall effect
a subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in Common Stock), then, and in each such case, Additional Shares of
Common Stock shall be deemed to have been issued (a) in the case of any such
dividend, immediately after the close of business on the record date for the
determination of holders of any class of securities entitled to receive such
dividend, or (b) in the case of any such subdivision, at the close of business
on the day immediately prior to the day upon which such corporate action becomes
effective.

         Section 2.6. COMPUTATION OF CONSIDERATION. For the purpose of Article
II, the following shall be used to determine the consideration received or
deemed received by the Company:

                  (a) SHARES ACTUALLY ISSUED. The consideration for the issue or
         sale of any Additional Shares of Common Stock shall, irrespective of
         the accounting treatment of such consideration,

                           (i) insofar as it consists of cash, be computed at
                  the net amount of cash received by the Company, without
                  deducting any expenses paid or incurred by the Company or any
                  commissions or compensations paid or concessions or discounts
                  allowed to underwriters, dealers or others performing similar
                  services in connection with such issue or sale,

                           (ii) insofar as it consists of property (including
                  securities) other than cash, be computed at the fair value
                  thereof at the time of such issue or sale, as determined in
                  good faith by the Board of Directors of the Company, and

                           (iii) in case Additional Shares of Common Stock are
                  issued or sold together with other stock or securities or
                  other assets of the Company for a consideration which covers
                  both, be the portion of such consideration so received,
                  computed as provided in clauses (i) and (ii) above, applicable
                  to such Additional Shares of Common Stock, all as determined
                  in good faith by the Board of Directors of the Company.

                  (b) SHARES DEEMED ISSUED. Additional Shares of Common Stock
         deemed to have been issued pursuant to Section 2.4, relating to Options
         and Convertible Securities, shall be deemed to have been issued for a
         consideration per share determined by dividing,

                           (i) the present value (using a discount factor equal
                  to the average interest rate on the Company's outstanding
                  indebtedness to financial institutions and assuming any
                  consideration receivable by the Company shall be received at
                  the latest date possible under the terms of such Options or
                  Convertible Securities) of the total amount, if any, received
                  and receivable by the Company as consideration for the issue,
                  sale, grant or assumption of the Options or Convertible
                  Securities in question, plus the present value (using a
                  discount factor equal to the average interest rate on the
                  Company's outstanding indebtedness to financial institutions

                                       4
<PAGE>

                  and assuming any consideration receivable by the Company shall
                  be received at the latest date possible under the terms of the
                  Options and Convertible Securities) of the minimum aggregate
                  amount of additional consideration (as set forth in the
                  instruments relating thereto, without regard to any provision
                  contained therein for a subsequent adjustment of such
                  consideration to protect against dilution) payable to the
                  Company upon the exercise in full of such Options or the
                  conversion or exchange of such Convertible Securities or, in
                  the case of Options for Convertible Securities, the exercise
                  of such Options for Convertible Securities and the conversion
                  or exchange of such Convertible Securities, in each case
                  computing such consideration as provided in the foregoing
                  subdivision (a), by

                           (ii) the maximum number of Additional Shares of
                  Common Stock (as set forth in the instruments relating
                  thereto, without regard to any provision contained therein for
                  a subsequent adjustment of such number to protect against
                  dilution) issuable upon the exercise of such Options or the
                  conversion or exchange of such Convertible Securities.

                  (c) STOCK DIVIDENDS, ETC. Additional Shares of Common Stock
         issued or deemed to have been issued pursuant to Section 2.5, relating
         to stock dividends, stock splits, etc., shall be deemed to have been
         issued for no consideration.

                  (d) SERVICES. Additional Shares of Common Stock issued or sold
         or deemed issued or sold in exchange for services or the promise of
         future services shall be deemed to have been issued for no
         consideration.

         Section 2.7. ADJUSTMENTS FOR COMBINATIONS, ETC. In case the outstanding
shares of Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the Warrant Price in
effect immediately prior to such combination or consolidation shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately increased.

         Section 2.8. DILUTION IN CASE OF OTHER SECURITIES. In case any Other
Securities shall be issued or sold or shall become subject to issue or sale upon
the conversion or exchange of any stock (or Other Securities) of the Company (or
any issuer of Other Securities or any other Person referred to in Article II) or
to subscription, purchase or other acquisition pursuant to any Options issued or
granted by the Company (or any such other issuer or Person) for a consideration
such as to dilute, on a basis consistent with the standards established in the
other provisions of this Article II, the purchase rights granted by this
Warrant, then, and in each such case, the computations, adjustments and
readjustments provided for in this Article II with respect to the Warrant Price
shall be made as nearly as possible in the manner so provided and applied to
determine the amount of Other Securities from time to time receivable upon the
exercise of the Warrant, so as to protect the holder of the Warrant against the
effect of such dilution.

         Section 2.9. APPRECIATION RIGHTS. If the Company issues or sells
Appreciation Rights, a number of Additional Shares of Common Stock shall be
deemed issued for purposes of this Article II and shall be computed as follows:

                  (a) VALUE BASED ON DIVIDENDS. If the Appreciation Rights
         entitle the holder thereof to distributions or payments based on or
         determined with reference to dividends paid or payable on Common Stock,
         the number of Additional Shares of Common Stock deemed issued will be
         the number of shares of Common Stock that would be required to be
         issued such that the holder thereof would receive distribution payments
         equal to those paid or payable with respect to such Appreciation
         Rights.

                                       5
<PAGE>

                  (b) VALUE BASED ON LIQUIDATING DISTRIBUTIONS. If the
         Appreciation Rights entitle the holder thereof to distributions or
         payments based on or determined with reference to liquidation
         distributions paid or payable on, or consideration received, in
         connection with the sale, exchange or transfer of Common Stock, the
         number of Additional Shares of Common Stock deemed issued will be the
         number of shares of Common Stock that would be required to be issued
         such that the holder thereof would receive distributions or payments
         equal to those paid or payable with respect to such Appreciation
         rights.

                  (c) VALUE BASED ON DIVIDENDS AND LIQUIDATING DISTRIBUTIONS. If
         the Appreciation Rights entitle the holder thereof to distributions
         based on or determined with reference to either dividends paid or
         payable on Common Stock and liquidating distributions paid or payable
         or on consolidation received in connection with the sale, exchange or
         transfer of Common Stock, the number of Additional Shares of Common
         Stock deemed issued will be the greater of the amount computed under
         (a) or (b) above.

                  (d) OTHER PROFITS. If the Appreciation Rights entitle the
         holder thereof to distributions based on or determined with reference
         to any other measure of profit of the Company, the number of Additional
         Shares of Common Stock deemed issued will be the value of the
         Appreciation Right, as determined in the good faith judgment of the
         Board of Directors, divided by the Current Market Price of the Common
         Stock on the date of issuance of the Appreciation Right.

                    ARTICLE III. CONSOLIDATION, MERGER, ETC.

         Section 3.1. CONSOLIDATION, MERGER, SALE OF ASSETS, REORGANIZATION,
ETC. From and after the date hereof, without the prior consent of the holder of
this Warrant, the Company shall not (a) consolidate with or merge into any other
Person if the Company is not the continuing or surviving corporation of such
consolidation or merger, or (b) permit any other Person to consolidate with or
merge into the Company even though the Company shall be the continuing or
surviving Person if, in connection with such consolidation or merger, the Common
Stock or Other Securities shall be changed into or exchanged for stock or other
securities of any other Person or cash or any other property, or (c) transfer
all or substantially all of its properties or assets to any other Person, or (d)
effect a capital reorganization or reclassification of the Common Stock or Other
Securities (other than a capital reorganization or reclassification resulting in
the issue of Additional Shares of Common Stock for which adjustment in the
Warrant Price is provided in Section 2.2 or 2.3).

         Section 3.2. ASSUMPTION OF OBLIGATIONS. Notwithstanding anything
contained in this Warrant to the contrary, the Company will not effect any of
the transactions described in clauses (a) through (d) of Section 3.1 unless,
prior to the consummation thereof, each Person (other than the Company) which
may be required to deliver any stock, securities, cash or property upon the
exercise of this Warrant as provided herein shall assume, by written instrument
delivered to, and reasonably satisfactory to, the holder of this Warrant, (a)
the obligations of the Company under this Warrant (and if the Company shall
survive the consummation of such transaction, such assumption shall be in
addition to, and shall not release the Company from, any continuing obligations
of the Company under this Warrant) and (b) the obligation to deliver to such
holder such shares of stock, securities, cash or property as such holder may be
entitled to receive. Nothing in this Article III shall be deemed to authorize
the Company to enter into any transaction not otherwise permitted by the Loan
Agreement.

                ARTICLE IV. OTHER PROVISIONS CONCERNING DILUTION

         Section 4.1. OTHER DILUTIVE EVENTS. In case any event shall occur as to
which the provisions of Article II or III are not strictly applicable but the
failure to make any adjustment would not fairly protect the purchase rights
represented by this Warrant in accordance with the essential intent and
principles of such sections, then, in each such case, the Company shall appoint
a firm of independent certified public accountants of recognized national
standing (which may be the regular auditors of the Company), which shall give
their opinion upon the adjustment, if any, on a basis consistent with the
essential intent and principles established in Articles II and III, necessary to
preserve, without dilution, the purchase rights represented by this Warrant.
Upon receipt of such opinion, the Company will promptly mail a copy thereof to
the holder of this Warrant and shall make the adjustments described therein.

         Section 4.2. NO DILUTION OR IMPAIRMENT. The Company will not, by
amendment of its certificate of incorporation or through any consolidation,
merger, reorganization, transfer of assets, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the holder of this Warrant against dilution or other impairment. Without
limiting the generality of the foregoing, the Company (a) will not permit the
par value of any shares of stock receivable upon the exercise of this Warrant to
exceed the amount payable therefor upon such exercise, (b) will take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable shares of Common Stock on the
exercise of the Warrant from time to time outstanding, and (c) will not take any
action which results in any adjustment of the Warrant Price if the total number
of shares of Common Stock (or Other Securities) issuable after the action upon
the exercise of the Warrant would exceed the total number of shares of Common
Stock (or Other Securities) then authorized by the Company's certificate of
incorporation and available for the purpose of issuance upon such exercise.

         Section 4.3. ACCOUNTANT'S AND COMPANY'S REPORT AS TO ADJUSTMENTS. In
each case of any adjustment or readjustment in the shares of Common Stock (or
Other Securities) issuable upon the exercise of this Warrant, the Company at its
expense will promptly compute such adjustment or readjustment in accordance with
the terms of this Warrant and cause independent certified public accountants of
recognized national standing (which may be the regular auditors of the Company)
selected by the Company to verify such computation (other than any computation
of the fair value of property as determined in good faith by the Board of
Directors of the Company) and prepare a report setting forth such adjustment or
readjustment and showing in reasonable detail the method of calculation thereof
and the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or to be received by the Company for
any Additional Shares of Common Stock issued or sold or deemed to have been
issued, (b) the number of shares of Common Stock outstanding or deemed to be
outstanding, and (c) the Warrant Price in effect immediately prior to such issue
or sale and as adjusted and readjusted (if required by Article II) on account
thereof. The Company shall also prepare and certify a report stating that any
computation of the fair value of property by the Board of Directors was done in
good faith by the Board of Directors as required herein. The Company will
forthwith mail a copy of each such report to each holder of a Warrant and will,
upon the written request at any time of any holder of a Warrant, furnish to such
holder a like report setting forth the Warrant Price at the time in effect and
showing in reasonable detail the manner in which it was calculated. The Company
will also keep copies of all such reports at its office maintained pursuant to
subdivision (a) of Section 6.2 and will cause the same to be available for
inspection at such office during normal business hours by any holder of a
Warrant or any prospective purchaser of a Warrant designated by the holder
thereof.

following occurs,

         any class of securities for the purpose of determining the holders
         thereof who are entitled to receive any dividend (other than a regular
         periodic dividend payable in cash out of earned surplus in an amount
         not exceeding the amount of the immediately preceding cash dividend for
         such period) or other distribution, or any right to subscribe for,
         purchase or otherwise acquire any shares of stock of any class or any
         other securities or property, or to receive any other right, or

                  (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any consolidation or merger involving the Company and any
         other Person or any transfer of all or substantially all the assets of
         the company to any other Person, or

                  (c) any voluntary or involuntary dissolution, liquidation or
         winding-up of the Company,

the Company will mail to each holder of a Warrant a notice specifying (i) the
date or expected date as of which any such record is to be taken for the purpose
of such dividend, distribution or right, and the amount and character of such
dividend, distribution or right, and (ii) the date or expected date on which any
such reorganization, reclassification, recapitalization, consolidation, merger,
transfer, dissolution, liquidation or winding-up is to take place and the time,
if any such time is to be fixed, as of which the holders of record of Common
Stock (or Other Securities) shall be entitled to exchange their shares of Common
Stock (or Other Securities) for the securities or other property deliverable
upon such reorganization, reclassification, recapitalization, consolidation,
merger, transfer, dissolution, liquidation or winding-up. Such notice shall be
mailed at least 20 days prior to the date therein specified.

         Section 4.5. REGISTRATION OF COMMON STOCK. If any shares of Common
Stock required to be reserved for purposes of exercise of this Warrant require
registration with or approval of any governmental authority under any federal or
state law (other than the Securities Act) before such shares may be issued upon
exercise, the Company will, at its expense and as expeditiously as possible, use
its best efforts to cause such shares to be duly registered or approved, as the
case may be. At any such time as Common Stock is listed on any national
securities exchange, the Company will, at its expense, obtain the a notice of
issuance, of the shares of Common Stock issuable upon exercise of the Warrant
and maintain the listing of such shares after their issuance; and the Company
will also list on such national securities exchange, will register under the
Exchange Act and will maintain such listing of, any Other Securities that at any
time are issuable upon exercise of the Warrant, if and at the time that any
securities of the same class shall be listed on such national securities
exchange by the Company.

         Section 4.6. AVAILABILITY OF INFORMATION. The Company will cooperate
with each holder of any Warrant or Restricted Security in supplying such
information as may be reasonably requested by such holder to complete and file
any information reporting forms presently or hereafter required by the
Commission to report such holder's beneficial ownership of Common Stock or Other
Securities or as a condition to the availability of an exemption from the
provisions of the Securities Act for the sale of any Restricted Securities.

(or Other Securities) issuable upon exercise of the Warrant shall be duly
authorized and, when issued upon such exercise, shall be validly issued and, in
the case of shares, fully paid and non-assessable with no liability on the part
of the holders thereof.

         this Warrant have not been registered under the Securities Act of 1933,
         as amended, and may not be transferred, sold or otherwise disposed of
         in the absence of such registration or an exemption therefrom under

such notice (a) shall describe the manner and circumstances of the proposed
transfer and (b) shall include an opinion of legal counsel addressed to the
Company, in form and substance reasonably satisfactory to the Company, to the

this Article V upon the transferability of Restricted Securities shall cease and
terminate as to any particular Restricted Securities when such securities shall

Whenever such restrictions shall cease and terminate as to any Restricted
Securities, the holder thereof shall be entitled to receive from the Company,
without expense (other than applicable transfer taxes, if any), new certificates
representing the securities not bearing the applicable legends required by
Section 5.1.
