                   SOUTHWEST WATER COMPANY AND SUBSIDIARIES
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                MARCH 31, 2000
                                  (Unaudited)


1.   Southwest Water Company ("the Company" or "Registrant") together with its
     subsidiaries is in the business of managing all aspects of water and
     wastewater systems, and provides its services to more than one million
     people in 24 states. Through its wholly owned subsidiary, ECO Resources,
     Inc. ("ECO"), the Company operates and manages water and wastewater
     treatment facilities owned by cities, municipal utility districts and
     private entities. The Company owns and operates water and wastewater
     utilities through two wholly owned subsidiaries, Suburban Water Systems
     ("Suburban") and New Mexico Utilities, Inc. ("NMUI"). The unaudited
     condensed consolidated financial statements reflect all adjustments, which,
     in the opinion of management, are necessary to present fairly the financial
     position of the Company as of March 31, 2000, and the Company's results of
     operations for the three months ended March 31, 2000. All such adjustments
     are of a normal recurring nature. Certain reclassifications have been made
     to the 1999 financial statements to conform to the 2000 presentation.

2.   Certain information and footnote disclosures normally included in financial
     statements prepared in accordance with generally accepted accounting
     principles have been condensed or omitted pursuant to the rules and
     regulations of the Securities and Exchange Commission. These condensed
     consolidated financial statements should be read in conjunction with the
     financial statements and related notes contained in the Company's Annual
     Report on Form 10-K ("the 1999 Annual Report") for the year ended December
     31, 1999.

3.   There is seasonality to the water services industry; thus, the results
     of operations for the three months ended March 31, 2000 do not necessarily
     indicate the results to be expected for the full year. Rainfall and weather
     conditions affect utility operations, with most water consumption occurring
     during the third quarter of each year when weather tends to be hot and dry.
     Drought conditions would have the effect of lowering revenue due to
     conservation efforts. The Company's contract operations business can also
     be seasonal in nature. Heavy rainfall hampers the Company's ability to
     perform billable work such as pipeline maintenance, manhole rehabilitation
     and other outdoor services. Moderate rainfall may create additional
     opportunities for billable work outside the scope of existing contracts.
     Drought conditions would not necessarily affect the Company's opportunities
     for additional billable work.

4.   The Company records earnings per share ("EPS") by computing basic EPS and
     diluted EPS. Basic EPS is used to measure the performance of the Company
     over the reporting period by dividing net income available to common
     stockholders by the weighted average number of common shares outstanding
     during the period. Diluted EPS is used to measure the performance of the
     Company over the reporting period after giving effect to all dilutive
     potential common shares that would have been outstanding if the dilutive
     common shares had been issued. Stock options give rise to dilutive common
     shares.

5.   In April 2000, the Company purchased 80 percent of the outstanding shares
     of Master Tek International, Inc. ("Master Tek"), a nationwide provider of
     utility submetering, billing and collection services for a purchase price
     of $4,000,000. The purchase price consisted of a $2,000,000 cash payment
     upon closing and a ten-year promissory note. The purchase agreement
     provides that the Company has the right to acquire the remaining 20 percent
     ownership for a price based on a formula related to the financial
     performance of Master Tek over the next ten years. In addition, the Company
     entered into an employment agreement, a consulting agreement and a non-
     compete agreement with the owner of the remaining 20 percent of Master Tek
     as is customary in transactions of this type. Submetering involves the
     installation of electronic equipment in apartments, condominiums, mobile
     home parks and other multi-family dwellings to allow the measurement of
     water, gas and electricity usage for each individual residential unit.
     Master Tek serves more than 175,000 dwelling units in 24 states and, in
     1999, generated revenues of more than $5,000,000.

6.   As discussed in the 1999 Annual Report, Suburban purchased the City of West
     Covina's ("West Covina") water distribution system and facilities. On
     February 25, 2000, Suburban assumed ownership and operation of the water
     system. The transaction added approximately 7,000 connections to Suburban's
     customer base, an increase of approximately 11 percent. The purchase of the
     West Covina system was funded in part by the reinvestment of approximately
     $3,900,000 of proceeds from the sale of surplus land, as described fully in
     the Company's 1999 Annual Report. The remaining funds for the purchase were
     obtained from line of credit borrowing.

7.   As discussed in the 1999 Annual Report, the Company owns a 49 percent
     interest in Windermere Utility Company ("Windermere"), a small, regulated
     water utility located near Austin, Texas. The Company has an agreement with
     the majority shareholder under which the majority shareholder may purchase
     the Company's interest in Windermere for an agreed-upon price. The
     agreement, as amended, extends to May 31, 2000 the majority shareholder's
     right to exercise this purchase option. The Company is currently holding
     discussions with the majority shareholder of Windermere to purchase its
     interest in Windermere along with two other utilities, also located near
     Austin, Texas. The Company anticipates that negotiations will be completed
     in 2000.

8.   As discussed in the 1999 Annual Report, the City of Albuquerque
     ("Albuquerque") has initiated an action in eminent domain to acquire the
     operations of NMUI. In March 2000, certain members of the Albuquerque city
     council introduced a bill directing the city attorney to withdraw the
     condemnation and cease negotiations to acquire NMUI. However, in April
     2000, the bill was defeated, and the condemnation action remains pending.
     At present, Albuquerque is not prosecuting this action and there is no
     assurance that a settlement of the legal action or other resolution will be
     reached quickly.

9.   The Company has two reportable segments as defined under the requirements
     of SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
     Information." There was no change in the basis of segmentation or in the
     basis of measurement of segment profit or loss from the information
     reported in the 1999 Annual Report. The following table sets forth required
     disclosure about the Company's reportable segments as required by SFAS No.
     131.

Item 2:  Management's Discussion and Analysis of Financial Condition and Results
of Operations

Liquidity and capital resources of the Company are influenced primarily by
construction expenditures at Suburban and NMUI for the addition, replacement and
renovation of water utility facilities.  The Company's capital resources may
also be influenced by investments to acquire new business opportunities.

At March 31, 2000, the Company had cash and cash-equivalent balances totaling
$248,000 and three separate unsecured lines of credit from three commercial
banks, with total line of credit capacity of $20,000,000.  All of the lines
expire in 2001 and the Company expects to renew expiring lines of credit in the
normal course of business.  At March 31, 2000, outstanding borrowing was
$11,667,000, and the unused borrowing capacity was  $8,333,000.  In the first
quarter of 2000, the Company's outstanding line of credit borrowing increased
$5,074,000 primarily due to additional cash requirements for acquisitions and
investments made by the Company.  Under two of the line of credit agreements,
interest is charged at each banks' prime rate less one-quarter percent.  The
Company may also borrow at an interest rate that is lower than this rate;
however, the amount borrowed must remain outstanding for a fixed period of time.
Interest charged under the third line of credit is lower than the bank's prime
rate and contains no restrictions as to minimum borrowing or borrowing for a
fixed period of time.  Two of the lines of credit require a $6,000 annual fee,
and the remaining line of credit requires no annual fee.  Each of the line of
credit agreements, as amended, contains certain financial restrictions.  As of
March 31, 2000, the Company was in compliance with all applicable financial
covenants of the line of credit agreements.

In addition to its lines of credit, the Company has existing borrowing capacity
under its First Mortgage Bond Indentures. Under these indentures, the Company
has remaining borrowing capacity of approximately $47,855,000. However, the
amount of additional borrowing available to the Company under its current lines
of credit is limited by financial covenants that restricted additional borrowing
at March 31, 2000 to the unused credit line amount.

During the first quarter of 2000, the Company's additions to property, plant and
equipment were $10,147,000, representing an increase of $3,215,000 from 1999.
The increase was due primarily to the purchase of West Covina's water
distribution system and facilities, which accounted for $9,140,000 of the
additions. Other capital projects accounted for the remaining $1,007,000 of
additions. Developers made contributions in aid of construction ("CIAC"), and
advances totaling $477,000, of which $316,000 was received in cash and $161,000
was received as non-cash contributions of property. Company-financed capital
additions were $9,670,000, funded primarily by borrowing on the lines of credit,
cash flow from operations, and the reinvestment of proceeds from the sale of
surplus land as discussed in Note 6 to the condensed consolidated financial
statements. For the remainder of 2000, the Company estimates that its capital
additions will be approximately $7,200,000, and that cash flow from operations
and CIAC will fund these additions. Line of credit borrowing is also available
to meet construction requirements if needed.

The Company anticipates that its available line of credit borrowing capacity and
the cash flow generated from operations will be sufficient to fund its
activities during the next 12 months, including certain new business
investments.  If additional cash were needed, the Company would consider
alternative sources, including long-term financing.  The amount and timing of
any future long-term financing would depend on various factors, including the
timeliness and adequacy of rate increases, the availability of capital, and the
Company's ability to meet interest and fixed charge coverage requirements.
Regulatory approval is required for any long-term financing by Suburban or NMUI.
If the Company was unable to renew its existing lines of credit or unable to
obtain additional long-term financing, capital spending or acquisitions would be
reduced or delayed until new financing arrangements were secured.  Such
financing arrangements could include seeking equity financing through a private
placement or a public offering.  Similarly, if the Company needed additional
cash to fund an acquisition, financing arrangements could include long-term
borrowing or equity financing.

Regulatory Affairs:

  Regulation and Regulatory Developments

ECO has two distinct types of contractual relationships: time and material
contracts primarily with municipal utility districts ("MUDs"), and fixed fee
operations and maintenance contracts ("O&Ms").  A MUD is a utility district
created under the rules of the Texas Natural Resource Conservation Commission in
order to provide water, wastewater and drainage services to areas where existing
municipal services are not available.  O&M contracts are agreements with cities
and private entities that provide for a specified level of services such as
facility operation and maintenance, meter readings and billing, or management of
the entire water or wastewater system.  ECO's pricing is not subject to
regulation by a public utilities commission. Most contracts with MUDs are short-
term contracts and do not generally include inflation adjustments.  Changes in
prices are negotiated on a contract-by-contract basis. ECO's O&M contracts are
generally longer-term water and wastewater service contracts, primarily with
cities, and typically include inflation adjustments.

The California Public Utilities Commission ("CPUC") and the New Mexico Public
Regulation Commission ("NMPRC") regulate the rates and operations of Suburban
and NMUI, respectively.  The rates allowed are intended to provide the utilities
an opportunity to recover costs and earn a reasonable return on common equity.
Although neither utility is currently seeking any rate increase, future
construction expenditures and increased operating expenses may require periodic
requests for rate increases.  As discussed in the 1999 Annual Report, the CPUC
has directed Suburban to file a general rate application by July 1, 2001.


  Regulatory Developments:

The Company closely monitors legislative, CPUC and NMPRC developments. The
various water industry associations in which the Company actively participates
also monitor these developments. The Company does not know the future possible
legislative, CPUC or NMPRC changes that will be enacted or the terms of such
changes if enacted. Therefore, management cannot predict the impact, if any, of
future legislative changes, CPUC or NMPRC developments or changes on the
Company's financial position or results of operations.

Environmental Affairs:

As a contract operator, ECO does not own any of the water sources, water
production facilities, or water distribution systems that it operates for its
clients, nor does ECO own any of the wastewater collection systems or wastewater
treatment facilities that it operates for its clients.  Although not the owner,
ECO is responsible for operating these water and wastewater facilities in
compliance with all federal, state and local health standards and regulations.

Suburban and NMUI operations fall under the regulatory jurisdiction of the CPUC
and the NMPRC, respectively.  The responsibilities of both regulatory agencies
are to ensure an adequate supply of affordable, healthful, potable water to
residents of their respective states.  The Company's operations are also subject
to water and wastewater pollution prevention standards and water and wastewater
quality regulations of the Environmental Protection Agency ("EPA") and various
state regulatory agencies.  Both the EPA and state regulatory agencies require
periodic testing and sampling of water.  Costs associated with the testing of
the Company's water supplies have increased and are expected to increase further
as the regulatory agencies adopt additional monitoring requirements.  The
Company believes that future incremental costs of complying with governmental
regulations, including capital expenditures, will be recoverable through
increased rates and contract operations revenues.  However, there is no
assurance that recovery of such costs will be allowed. To date, the Company has
not experienced any material adverse effects upon its operations resulting from
compliance with governmental regulations.

As discussed in the Company's 1999 Annual Report, the Company has been named in
several complaints alleging water contamination in the Main San Gabriel Basin in
Southern California.  In September 1999, the California 2nd District Court of
Appeal ordered that the lawsuits be dismissed.  The

California Supreme Court has agreed to review this decision. The Company
anticipates that the Supreme Court will hear the case during 2000.

As discussed in the Company's 1999 Annual Report, in March 1998, the CPUC issued
an order instituting investigation ("OII") directed to all Class A and B water
utilities in California, including Suburban. The purpose of the OII is to
address a series of questions dealing with the safety of current drinking water
standards and compliance with those standards. In February 2000, the CPUC issued
a draft opinion finding that the California Department of Health Services
("DOHS") requirements governing drinking water quality adequately protect the
public health and safety, and that the regulated water utilities have complied
with past and present drinking water quality requirements. While the CPUC
continues to investigate the issues concerned with water quality, the Company
and Suburban are unable to predict what final actions, if any, will be taken by
the CPUC and/or the DOHS as the result of this investigation, or their impact on
the operations or financial position of the Company and Suburban.

Risk Factors:

Certain statements contained in this Report on Form 10-Q for the quarter ended
March 31, 2000 ("the March Report") that are not based on historical fact are
"forward-looking" statements within the meaning of the Private Securities
Litigation Reform Act of 1995. These statements are only projections. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause actual results, performance or achievements of the
Company to be materially different from any performance or achievements planned,
expressed or implied by such forward-looking statements. Although the Company
believes that its expectations are based on reasonable assumptions within the
bounds of its knowledge of its business and operations, there can be no
assurance that actual results will not differ materially from its expectations.

The March Report should be read in conjunction with the Company's 1999 Annual
Report for a more detailed description of the risk factors affecting the Company
which include, but are not limited to, expectations regarding new contracts and
potential acquisitions, weather conditions, water quality issues, regulatory
changes, legal and other contingencies.

Results of Operations:

Three Months Ended March 31, 2000 Compared To Three Months Ended March 31, 1999

Diluted earnings per common share were $.06 in 2000, an increase of 20%,
compared to $.05 during the same period in 1999.

  Operating income

Operating income increased $195,000 or 17%, and, as a percentage of operating
revenues, was 7% in both 2000 and 1999.  ECO's operating income increased
$83,000, due to the addition of new contracts and an increase in the amount of
project work performed outside the scope of existing contracts primarily in the
central Texas region.  Operating income at the utilities increased $134,000, due
primarily to a 5% increase in water consumption by Suburban's customers during a
mild and dry first quarter, which contributed to a 7% increase in utility
operating income.  Parent company expenses increased $22,000, due primarily to
an increase in payroll and benefit-related costs.

  Operating revenues

Operating revenues increased $3,908,000 in the first quarter of 2000 compared
with the same period in 1999.  ECO's revenues increased $3,495,000 or 39%, due
primarily to new contracts and to an increase in the amount of project work
performed outside the scope of existing contracts.  Utility revenues increased
$413,000.  Suburban's revenues increased 6% due primarily to increased customer
water consumption because of mild first quarter weather.  NMUI increased its
number of customers by 311, contributing to a 16% increase in water consumption,
and a 9% increase in water revenue.

<PAGE>

  Direct operating expenses

Direct operating expenses increased $3,537,000 or 28%.  As a percentage of
operating revenues, these expenses were 78% in 2000 and 75% in 1999.  ECO's
direct operating expenses increased $3,409,000, primarily as a result of new
contracts and the increase in the amount of project work performed outside the
scope of existing contracts. Suburban's direct operating expenses increased
$151,000, primarily due to increased water purchases resulting from higher
customer water consumption.  NMUI's direct operating expenses decreased $23,000
due to lower production and distribution expenses.

  Selling, general and administrative

Selling, general and administrative expenses for the first quarter of 2000
increased $176,000 as compared with the same period in 1999.  As a percentage of
operating revenues, these expenses were 15% in 2000 and 18% in 1999.  General
and administrative expenses at the utilities increased $154,000, because of a
decrease in the amount of capitalized administrative overhead at both Suburban
and NMUI.  As discussed above, general and administrative expenses of the parent
company increased $22,000.

  Other

Interest expense increased $29,000 as a result of the increase in line of credit
borrowing in late February to finance the West Covina acquisition.  The increase
also reflects higher interest rates in 2000 compared to 1999.

                          PART II - OTHER INFORMATION

Item 1:  Legal Proceedings

As discussed in the Company's 1999 Annual Report, ECO was named as a defendant
in four lawsuits alleging injury and damages as the result of a sewage spill,
which occurred at an Austin, Texas sewage pumping station. The case is presently
in the discovery stage. No oral depositions have been taken and there have been
no court hearings. The Company and ECO intend to vigorously defend against these
claims and have requested defense and indemnification by their insurance
carrier. At this time, the Company does not believe this matter will have a
material adverse effect on the Company's financial position or results of
operations.

As discussed in the Company's 1999 Annual Report, the Company has been named in
several complaints alleging water contamination in the Main San Gabriel Basin in
Southern California (the "Main Basin").  In September 1999, the California 2nd
District Court of Appeal ordered that the lawsuits be dismissed.  The California
Supreme Court has agreed to review this decision.  The Company anticipates that
the California Supreme Court will hear the oral argument during 2000.  The
Company and Suburban have requested defense and indemnification from their
liability insurance carriers for these lawsuits.  Several of the liability
insurance carriers are currently contributing to the costs of defense of the
lawsuits.  Two additional lawsuits similar to those described in this paragraph
were filed in April 2000 by approximately 240 plaintiffs against Suburban, the
Company, other water producers in the Main Basin and a number of alleged
industrial polluters.  The actions have not yet been served on the Company or
Suburban.  The Company expects to defend the new actions on the same basis as
the earlier actions. Based upon information available at this time, management
does not expect that these actions will have a material adverse effect on the
Company's financial position or results of operations.

As discussed in the Company's 1999 Annual Report, in October 1998 the Company
and ECO were sued in an action in Texas arising out of a fatal auto accident.
The Company believes that its maximum exposure in this action is limited to the
self-insured retention under its umbrella liability policy.  Based on the
information available at this time, management does not expect that this action
will have a material adverse effect on the Company's financial position or
results of operations.

As discussed in Note eight to the condensed consolidated financial statements,
Albuquerque initiated an action in eminent domain to acquire the operations of
NMUI.  The Company believes that the fair market value of NMUI is substantially
in excess of the amount offered in Albuquerque's complaint.  Under New

                                       9
<PAGE>

Mexico state law, there are procedures that would allow Albuquerque to take
possession prior to a resolution of the fair market value issue; however, the
Company believes that it has adequate defenses should Albuquerque choose to
pursue these procedures. Presently, Albuquerque is not prosecuting this action
and there is no assurance that a settlement of the legal action or any other
resolution will be reached quickly.

The Company and its subsidiaries are the subjects of certain litigation arising
from the ordinary course of operations. The Company believes the ultimate
resolution of such matters will not materially affect its consolidated financial
position, results of operations or cash flow.

</TABLE>

First Security Bank of New Mexico, N.A. ("Lender") has extended the credit (the
"Loan") to New Mexico Utilities, Inc. (individually and collectively "Borrower")
pursuant to a promissory note dated December 10, 1997 (the "Note") in the stated
principal amount of $4,000,000.00.  The Loan is unsecured.

The Note and any loan agreements, guaranties, subordinations, Collateral
Documents and other instruments and documents executed in connection therewith,
together with any previous modifications to any of these instruments or
documents shall be referred to as the "Loan Documents".

Borrower has requested certain modifications to the Loan Documents and Lender is
willing to grant such modifications on the following terms and conditions:

      1.  Provided that all conditions stated herein are satisfied, the terms of
          the Loan Documents are hereby modified as follows:

          Modifications to the Terms of the Note
          --------------------------------------
          The maturity date of the Note is extended to April 10, 2001,

          The interest rate under the Note is modified effective April 10, 2000.
          The interest rate on this Agreement is subject to change from time to
          time based on changes in an index which is the British Bankers
          Association quoted through Telerate System (the "Index").  The Index
          is that interest rate determined by Lender as the rate quoted by the
          British Bankers Association through the Dow Jones Telerate System
          Report (or such other similar source as may be selected by Lender) as
          the London Interbank Offered Rate (LIBOR) for deposits of United
          States dollars for one month maturity.  Lender will tell Borrower the
          current Index rate upon Borrower's request.  Borrower understands that
          Lender may make loans based on other rates as well.  The interest rate
          change will not occur more often than each day.  The Index currently
          is 6.132% per annum.  The interest rate to be applied to the unpaid
          principal balance of this agreement will be at 1.250 percentage points
          over the Index, resulting in an initial rate of 7.382% per annum.
          NOTICE: Under no circumstances will the interest rate on this
          Agreement be more than the maximum rate allowed by applicable law.

          This Agreement does not constitute a repayment or extinguishments of
          the Note, but only a modification thereof.

      2.  As preconditions to the terms of this Agreement, Borrower shall
          complete or provide the following

          Borrower shall pay or shall have paid all reasonable fees, costs, and
          expenses, of whatever kind or nature, incurred by Lender in connection
          with this Agreement, including but not limited to attorney's fees,
          lien search fees, title reports and pollicies, and recording and
          filing fees.
<PAGE>

      3.  It is the intention and agreement of Borrower and Lender that: (I) all
          collateral security in which Lender has acquired a security interest
          or other lien pursuant to the Loan Documents shall continue to serve
          as collateral security for payment and performance of all the
          obligations of the Borrower under the Loan Documents, and (iii) all
          agreements, representations, warranties and covenants contained in the
          Loan Documents are hereby reaffirmed in full by borrower except as
          specifically modified by this Agreement

      4.  Borrower hereby acknowledges that: (I) the Loan Documents are in full
          force and effect, as modified by this Agreement, and (ii) by entering
          into this Agreement, Lender does not waive any existing default or any
          default hereafter occurring or become obligated to waive any condition
          or obligation under the Loan Documents.

      5.  Borrower hereby acknowledges that Borrower has no claim, demand,
          lawsuit, cause of action, claim for relief, remedy, or defense against
          enforcement of the Loan Documents that could be asserted against
          Lender, its affiliates, directors, officers, employees, or
          representations, commitments, statements or warranties, including
          without limitation any such conduct arising out of or in any way
          connected with the Loan Documents. Notwithstanding the foregoing,
          Borrower hereby waives, releases and relinquishes any and all claims,
          demands, lawsuits, causes of action, claims for relief, remedies or
          defenses against enforcement of the Loan Documents that could be
          asserted against Lender, its affiliates, directors, officers,
          employees or agents, whether known or unknown.

      6.  In addition to this Agreement, the Loan Documents, and any additional
          documents that this Agreement requires, this finance transaction may
          include other written closing documentation such as resolutions,
          waivers, certificates, financing statements, filings, statements
          closing or escrow instructions, loan purpose statements, and other
          documents that Lender may customarily use in such transactions. Such
          documents are incorporated herein by this reference. All the documents
          to which this paragraph makes reference express, embody and supercede
          any previous understandings, agreements, or promises (whether oral or
          written) with respect to this finance transaction, and represent the
          final expression of the agreement between Lender and Borrower, the
          terms and conditions of which cannot hereafter by contradicted by any
          oral understanding (if any) not reduced to writing and identified
          above.

     WRITTEN AGREEMENTS.  Borrower acknowledges that Borrower is aware of the
     provisions of Section 58-6-5 NMSA 1978 Comp, which requires a contact,
     promise or commitment to loan money or to grant, extend, or renew credit or
     any modification thereof, in an amount greater that twenty-five thousand
     dollars ($25,000), not primarily for personal, family or household
     purposes, to be in wiring and signed by the party to be charged or that
     party's authorized representative.

     Effective as of April 10, 2000.

the same business relationships with the Company after the Closing as it
maintained with the Company prior to the Closing. Each of the Sellers will refer
all customer inquiries relating to the businesses of the Company to the Buyer
from and after the Closing. Should Milton DiGregorio voluntarily terminate his
employment with the Company, the event of his termination shall not by itself be
deemed to be a breach of this Section 6(b).

          (c)  Confidentiality. Each of the Sellers will treat and hold as such
               ---------------
all of the Confidential Information, refrain from using any of the Confidential
Information except in connection with this Agreement, and deliver promptly to
the Buyer or destroy, at the request and option of the Buyer, all tangible
embodiments (and all copies) of the Confidential Information which are in his or
its possession. In the event that any of the Sellers is requested or required
(by oral question or request for information or documents in any legal
proceeding, interrogatory, subpoena, civil investigative demand, or similar
process) to disclose any Confidential Information, that Seller will notify the
Buyer promptly of the request or requirement so that the Buyer may seek an
appropriate protective order or waive compliance with the provisions of this
Section 6(c). If, in the absence of a protective order or the receipt of a
waiver hereunder, any of the Sellers is, on the advice of counsel, compelled to
disclose any Confidential Information to any tribunal or else stand liable for
contempt, that Seller may disclose the Confidential

                                       21
<PAGE>

Information to the tribunal; provided, however, that the disclosing Seller shall
use his or its reasonable efforts to obtain, at the request of the Buyer, an
order or other assurance that confidential treatment will be accorded to such
portion of the Confidential Information required to be disclosed as the Buyer
shall designate. The foregoing provisions shall not apply to any Confidential
Information which is generally available to the public immediately prior to the
time of disclosure.

          (d)  Covenant Not to Compete. As set forth in and subject to the
               -----------------------
provisions of that certain Non-Competition Agreement, the DiGregorios shall not,
for a period of ten (10) years from and after the Closing Date, engage directly
or indirectly in any business that the Company conducts as of the termination of
Employee's employment pursuant to the Employment Agreement. The Parties
acknowledge that the Non-Competition Agreement is a material inducement to the
purchase and sale of the Company Shares pursuant to this Agreement.

          (e)  Continued Employment. Buyer shall not, for a period of up to six
               --------------------
(6) months following the Closing Date, terminate any employee of the Company
without cause (other than Milton DiGregorio under the terms of his Employment
Agreement executed in conjunction herewith) without the approval of Milton
DiGregorio, which approval shall not be unreasonably withheld. (f) Sellers'
Vehicles. The DiGregorios accept the Sellers' Vehicles "as is, where is." The
DiGregorios shall pay all taxes, transfer fees, title fees, license fees and the
like with respect to the transfer of title to and ownership of the Sellers'
Vehicles.

     8.   Remedies for Breaches of This Agreement.
          ---------------------------------------

          (a)  Survival of Representations, Warranties and Covenants. All of
               -----------------------------------------------------
the representations and warranties of the Parties shall survive the Closing
hereunder and continue in full force and effect for a period equal to the
applicable statute of limitations on any actions with respect to such matters.

          (b)  Indemnification Provisions for Benefit of the Buyer. In the event
               ---------------------------------------------------
any of the Sellers breaches (or in the event any third party alleges facts that,
if true, would mean any of the Sellers has breached) any of their
representations, warranties or covenants contained herein, provided that the
Buyer makes a written claim for indemnification against any of the Sellers
pursuant to Section 8(d) below within the applicable survival period set forth
in Section 8(a), then each of the Sellers agrees jointly and severally to
indemnify the Buyer from and against the entirety of any Adverse Consequences
the Buyer may suffer through and after the date of the claim for indemnification
(including any Adverse Consequences the Buyer may suffer after the end of any
applicable survival period) resulting from, arising out of, relating to, in the
nature of, or caused by the breach (or the alleged breach).

          (c)  Indemnification Provisions for Benefit of the Sellers. In the
               -----------------------------------------------------
event the Buyer breaches (or in the event any third party alleges facts that, if
true, would mean the Buyer has breached) any of its representations, warranties,
and covenants contained herein, provided that any of the Sellers makes a written
claim for indemnification against the Buyer pursuant to Section 8(d) below
within the applicable survival period set forth in Section 8(a), then the Buyer
agrees to indemnify each of the Sellers from and against the entirety of any
Adverse Consequences the Seller may suffer through and after the date of the
claim for indemnification (including any Adverse Consequences the Seller may
suffer after the end of any applicable survival period) resulting from, arising
out of, relating to, in the nature of, or caused by the breach (or the alleged
breach).

          (d)  Indemnification Procedures.
               --------------------------

               (i)  If any third party shall notify any Party (the "Indemnified
                                                                    -----------
          Party") with respect to any matter (a "Third Party Claim") which may
          -----                                  -----------------
          give rise to a claim for indemnification against any other Party (the
          "Indemnifying Party") under this Section 8, then the Indemnified Party
           ------------------
          shall promptly notify each Indemnifying Party thereof in writing;
          provided, however, that no delay on the part of the Indemnified Party
          --------  -------
          in notifying any Indemnifying Party shall relieve the Indemnifying
          Party from any obligation hereunder unless (and then solely to the
          extent) the Indemnifying Party thereby is prejudiced.

               (ii) Any Indemnifying Party will have the right to defend the
          Indemnified Party against the Third Party Claim with counsel of its
          choice reasonably satisfactory to the Indemnified Party so long as (A)
          the Indemnifying Party notifies the Indemnified Party in writing
          within fourteen (14) days after the Indemnified Party has given notice
          of the Third Party Claim that the Indemnifying Party will indemnify
          the Indemnified Party from and against the entirety of any Adverse
          Consequences the Indemnified Party may suffer resulting from, arising

                                       25
<PAGE>

          out of, relating to, in the nature of, or caused by the Third Party
          Claim, (B) the Indemnifying Party provides the Indemnified Party with
          evidence reasonably acceptable to the Indemnified Party that the
          Indemnifying Party will have the financial resources to defend against
          the Third Party Claim and fulfill its indemnification obligations
          hereunder, (C) the Third Party Claim involves only money damages and
          does not seek an injunction or other equitable relief, (D) settlement
          of, or an adverse judgment with respect to, the Third Party Claim is
          not, in the good faith judgment of the Indemnified Party, likely to
          establish a precedential custom or practice materially adverse to the
          continuing business interests of the Indemnified Party, and (E) the
          Indemnifying Party conducts the defense of the Third Party Claim
          actively and diligently.

               (iii)  So long as the Indemnifying Party is conducting the
          defense of the Third Party Claim in accordance with Section 8(d)(ii)
          above, (A) the Indemnified Party may retain separate co-counsel at its
          sole cost and expense and participate in the defense of the Third
          Party Claim, (B) the Indemnified Party will not consent to the entry
          of any judgment or enter into any settlement with respect to the Third
          Party Claim without the prior written consent of the Indemnifying
          Party (not to be withheld unreasonably), and (C) the Indemnifying
          Party will not consent to the entry of any judgment or enter into any
          settlement with respect to the Third Party Claim without the prior
          written consent of the Indemnified Party (not to be withheld
          unreasonably).

               (iv)   In the event any of the conditions in Section 8(d)(ii)
          above is or becomes unsatisfied, however, (A) the Indemnified Party
          may defend against, and consent to the entry of any judgment or enter
          into any settlement with respect to, the Third Party Claim in any
          manner it reasonably may deem appropriate (and the Indemnified Party
          need not consult with, or obtain any consent from, any Indemnifying
          Party in connection therewith), (B) the Indemnifying Parties will
          reimburse the Indemnified Party promptly and periodically for the
          costs of defending against the Third Party Claim (including reasonable
          attorneys' fees and expenses), and (C) the Indemnifying Parties will
          remain responsible for any Adverse Consequences the Indemnified Party
          may suffer resulting from, arising out of, relating to, in the nature
          of, or caused by the Third Party Claim to the fullest extent provided
          in this Section 8.

               (v)    In the event that the claim for indemnification does not
          involve a claim by a third party, but instead is a claim by Buyer
          against Seller or Seller against Buyer, the Indemnified Party shall
          give the Indemnifying Parties notice of the alleged breach. The
          Indemnifying Parties shall have thirty (30) days to cure such breach,
          if the breach is of the type that can be cured. If the breach cannot
          be cured, or has not been cured after the expiration of the cure
          period, then the Indemnifying Parties shall promptly pay the
          Indemnified Party the amount of the claim to the fullest extent
          provided in this Section 8.

                                       26
<PAGE>

               (vi)  Notwithstanding anything to the contrary in this Agreement,
          the Buyer shall not have any right to receive any indemnification
          payment from the Sellers for any claims until:

                     (A)  The Sellers have exhausted all coverage available from
               insurance carried by Buyer or the Company with respect to such
               claims; and

                     (B)  The Buyer has accrued an aggregate of $25,000 of
               claims in excess of the claims covered by insurance.

               (vii) Notwithstanding anything to the contrary in this Agreement:

                     (A)  The Buyer shall not have any right to receive any
               indemnification payment from the Sellers in an amount in excess
               of the aggregate of the (x) principal amount then outstanding
               under the Promissory Note, (y) the then remaining payments under
               the Noncompetition Agreement and (z) the maximum amount then
               payable to Sellers in the event of a full exercise of Sellers'
               remaining Put Rights under the Master Tek Shareholders Agreement;
               such maximum amount shall be determined as of the date of the
               notice to Sellers that Buyer is seeking indemnification; and

                     (B)  The Buyer shall have no right to proceed against any
               assets of the Sellers other than their interest in the Promissory
               Note, Noncompetition Agreement and Master Tek Shareholder
               Agreement. This provision shall survive Closing and shall control
               in the event of a conflict with any provision of any document
               executed at Closing of the transactions contemplated by this
               Agreement.

          (e)  Rights of Offset. In the event the Sellers have denied the
               ----------------
Buyer's request for indemnification, in whole or in part, the Buyer shall have
the option of recouping all or any part of any Adverse Consequences it may
suffer by filing suit against the Sellers pursuant to Section 11(h) below and
notifying the Sellers in writing that the Buyer is exercising its rights of
offset under this Section 8(e).

               (i)   While Buyer's action against the Sellers is pending, Buyer
          shall have the right to withhold or to direct the Company to withhold,
          as applicable, (1) the principal payments due under the Promissory
          Note (but must continue to pay the interest to Sellers), (2) the
          Noncompetition Payments (as defined in the Noncompetition Agreement)
          and (3) any amounts due under a "Put Right" as defined in the Master
          Tek Shareholder Agreement (collectively, the "Withholds").

               (ii)  Buyer or the Company, as applicable, must pay the Withholds
          as they become due to a court registry or the escrow established
          pursuant to the Collateral Agreement, will be considered as payments
          made in a timely manner under each of the Promissory Note,
          Noncompetition Agreement and Master Tek

                                       27
<PAGE>

          Shareholder Agreement, and shall not constitute a default under any of
          such agreements.

               (iii) The Withholds shall not exceed (1) the amount Buyer
          reasonably believes the indemnification claim is worth, net of the
          amounts set forth in Section 8(d)(vi), or (2) the maximum limit on
          indemnification established by Section 8(d)(vii).

               (iv)  In the event that Buyer prevails on its claim for
          indemnification against Sellers, Buyer and Sellers shall direct the
          registry or escrow agent to release the Withholds deposited therein in
          accordance with this Section to Buyer. The recoupment by Buyer of any
          principal amounts under the Promissory Note shall affect the timing
          and amount of payments required under the Promissory Note in the same
          manner as if the Maker (as defined in the Promissory Note) had made a
          permitted prepayment (without premium or penalty) thereunder and
          recoupment of payments under the Noncompetition Agreement and Master
          Tek Shareholder Agreement shall constitute regular payments under each
          of those Agreements.

               (v)   In the event that Buyer does not prevail on its claim for
          indemnification against Sellers, (1) Buyer and Seller shall direct the
          registry or escrow agent to release the Withholds deposited therein in
          accordance with this Section to the Sellers, and (2) Buyer shall make
          to the Sellers an accelerated payment of principal under the
          Promissory Note in an amount equal to twice the principal amount of
          the Promissory Note actually withheld as part of the Withholds (the
          aggregate payment not to exceed the maximum amount of principal then
          remaining under the Promissory Note). The accelerated payment of
          principal under the Promissory Note to Sellers shall affect the timing
          and amount of payments required under the Promissory Note in the same
          manner as if the Maker had made a permitted prepayment (without
          premium or penalty) thereunder.

          (f)  Other Indemnification Provisions. Subject to the provisions of
               --------------------------------
Section 8(d)(vii), the foregoing indemnification provisions are in addition to,
and not in derogation of, any statutory, equitable, or common law remedy any
Party may have for breach of representation, warranty, or covenant. Each of the
Sellers hereby agrees that he, she or it will not make any claim for
indemnification against the Company by reason of the fact that he, she or it was
a director, officer, employee, or agent of any such entity or was serving at the
request of any such entity as a partner, trustee, director, officer, employee,
or agent of another entity (whether such claim is for judgments, damages,
penalties, fines, costs, amounts paid in settlement, losses, expenses, or
otherwise and whether such claim is pursuant to any statute, charter document,
bylaw, agreement, or otherwise) with respect to any action, suit, proceeding,
complaint, claim, or demand brought by the Buyer against such Seller (whether
such action, suit, proceeding, complaint, claim, or demand is pursuant to this
Agreement, applicable law, or otherwise).

          (g)  Limitation of Seller's Liability to the Company. The Parties
               -----------------------------------------------
hereby agree that any and all claims, counterclaims, demands, actions and causes
of action, suits, rights, liabilities,

                                       28
<PAGE>

debts, contracts, duties and obligations, of any kind and nature whatsoever,
whether known or unknown, whether arising under common law, in equity or any
statute, which the Company ever had, now has, or in the future may claim to have
against Sellers and which have arisen at any time on or prior to the date of
that certain Release and Limitation of Liability between Sellers and the Company
("Company Claims"), shall be included within the limitations and requirements
established by Section 8(d)(vi) and (vii) and Section 8(e) as though they were
claims for indemnification under this Agreement. In no event shall the total of
Buyer's claims for indemnification and the Company Claims ever exceed the
limitations established by Section 8(d)(vi) and (vii) and Section 8(e).

     9.   Tax Matters. The following provisions shall govern the allocation of
          -----------
responsibility as between Buyer and Sellers for certain tax matters following
the Closing Date:

          (a)  Section 338(h)(10) Election. The Sellers and Buyer agree that no
               ---------------------------
Party shall make an election under Section 338(h)(10) of the Code with respect
to the purchase and sale of the stock of the Company hereunder.

          (b)  Tax Periods Ending on or Before the Closing Date. Buyer shall
               ------------------------------------------------
prepare or cause to be prepared and file or cause to be filed all Tax Returns
for the Company for all periods ending on or prior to the Closing Date which are
filed after the Closing Date. Buyer shall permit Sellers to review and comment
on each such Tax Return described in the preceding sentence prior to filing and
shall permit Sellers to contest on reasonable grounds any taxes, penalties or
interest imposed by the taxing authorities. Sellers shall reimburse Buyer for
Taxes of the Company with respect to such periods within fifteen (15) days after
payment by Buyer or the Company of such Taxes.

          (c)  Tax Periods Beginning Before and Ending After the Closing Date.
               --------------------------------------------------------------
Buyer shall prepare or cause to be prepared and file or cause to be filed any
Tax Returns of the Company for Tax periods which begin before the Closing Date
and end after the Closing Date. Sellers shall pay to Buyer within fifteen (15)
days after the date on which Taxes are paid with respect to such periods an
amount equal to the portion of such Taxes which relates to the portion of such
Taxable period ending on the Closing Date. For purposes of this Section, in the
case of any Taxes that are imposed on a periodic basis and are payable for a
Taxable period that includes (but does not end on) the Closing Date, the portion
of such Tax which relates to the portion of such Taxable period ending on the
Closing Date shall (x) in the case of any Taxes other than Taxes based upon or
related to income or receipts, be deemed to be the amount of such Tax for the
entire Taxable period multiplied by a fraction the numerator of which is the
number of days in the Taxable period ending on the Closing Date and the
denominator of which is the number of days in the entire Taxable period, and (y)
in the case of any Tax based upon or related to income or receipts be deemed
equal to the amount which would be payable if the relevant Taxable period ended
on the Closing Date. Any credits relating to a Taxable period that begins before
and ends after the Closing Date shall be taken into account as though the
relevant Taxable period ended on the Closing Date. All determinations necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of the Company.

          (d)  Cooperation on Tax Matters.
               --------------------------

               (i)   Buyer, the Company and Sellers shall cooperate fully, as
          and to the extent reasonably requested by another Party, in connection
          with the filing of Tax Returns pursuant to this Section and any audit,
          litigation or other proceeding with respect to Taxes. Such cooperation
          shall include the retention and (upon the other Party's request) the
          provision of records and information which are reasonably relevant to
          any such audit, litigation or other proceeding and making employees
          available on a mutually convenient basis to provide additional
          information and explanation of any material provided hereunder. The
          Company agrees (A) to retain all books and records with respect to Tax
          matters pertinent to the Company relating to any taxable period
          beginning before the Closing Date until the expiration of the statute
          of limitations (and, to the extent notified by Buyer or Sellers, any
          extensions thereof) of the respective taxable periods, and to abide by
          all record retention agreements entered into with any taxing
          authority, and (B) to give the other Parties reasonable written notice
          prior to transferring, destroying or discarding any such books and
          records and, if another Party so requests, the Company shall allow
          such Party to take possession of such books and records.

               (ii)  Buyer and Sellers further agree, upon request, to use their
          commercially reasonable efforts to obtain any certificate or other
          document from any governmental authority or any other Person as may be
          necessary to mitigate, reduce or eliminate any Tax that could be
          imposed (including, but not limited to, with respect to the
          transactions contemplated hereby).

               (iii) Buyer and Sellers further agree, upon request, to provide
          the other Parties with all information that any Party may be required
          to report pursuant to Section 6043 of the Code and all Treasury
          Department Regulations promulgated thereunder.

          (e)  Certain Taxes. All transfer, documentary, sales, use, stamp,
               -------------
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement, shall be paid by Sellers
when due, and Sellers will, at their own expense, file all necessary Tax Returns
and other documentation with respect to all such transfer, documentary, sales,
use, stamp, registration and other Taxes and fees, and, if required by
applicable law, Buyer will, and will cause its affiliates to, join in the
execution of any such Tax Returns and other documentation.

          (f)  Changes in Accounting Methods. Notwithstanding any other
               -----------------------------
provision of this Agreement, Sellers shall not be liable for any taxes, or any
interest and penalties on taxes, that arise solely as a result of a change in
accounting methods of the Company after the Closing.

     10.  Termination.
          -----------

          (a)  Termination of Agreement. The Parties may terminate this
               ------------------------
Agreement as provided below:

                                       30
<PAGE>

               (i)   The Buyer and the Sellers may terminate this Agreement by
          mutual written consent at any time prior to the Closing.

               (ii)  the Buyer may terminate this Agreement by giving written
          notice to the Sellers at any time prior to the Closing (A) in the
          event any of the Sellers has breached any material representation,
          warranty, or covenant contained in this Agreement in any material
          respect and the breach has continued without cure for a period of five
          (5) days after the notice of breach or (B) if the Closing shall not
          have occurred on or before April 30, 2000, by reason of the failure of
          any condition precedent under Section 7(a) hereof (unless the failure
          results primarily from the Buyer itself breaching any representation,
          warranty, or covenant contained in this Agreement); and

               (iii) the Sellers may terminate this Agreement by giving written
          notice to the Buyer at any time prior to the Closing (A) in the event
          the Buyer has breached any material representation, warranty, or
          covenant contained in this Agreement in any material respect, the
          Sellers have notified the Buyer of the breach, and the breach has
          continued without cure for a period of five (5) days after the notice
          of breach or (B) if the Closing shall not have occurred on or before
          April 30, 2000, by reason of the failure of any condition precedent
          under Section 7(b) hereof (unless the failure results primarily from
          any of the Sellers themselves breaching any representation, warranty,
          or covenant contained in this Agreement).

          (b)  Effect of Termination. If any Party terminates this Agreement
               ---------------------
pursuant to Section 10(a) above, all rights and obligations of the Parties
hereunder shall terminate without any Liability of any Party to any other Party
(except for any Liability of any Party then in breach).

     11.  Miscellaneous.
          -------------

          (a)  Press Releases and Public Announcements. No Party shall issue any
               ---------------------------------------
press release or make any public announcement relating to the subject matter of
this Agreement without the prior written approval of the Buyer and the Sellers;
provided, however, that any Party may make any public disclosure it believes in
good faith is required by applicable law or any listing or trading agreement
concerning its publicly-traded securities (in which case the disclosing Party
will use its reasonable best efforts to advise the other Parties prior to making
the disclosure).

          (b)  No Third-Party Beneficiaries. This Agreement shall not confer any
               ----------------------------
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

          (c)  Entire Agreement. This Agreement, together with the Promissory
               ----------------
Note and the Agreements referred to in 7(a)(vi)-(xi), inclusive, constitutes the
entire agreement among the Parties and supersedes any prior understandings,
agreements, or representations by or among the Parties, written or oral, to the
extent they related in any way to the subject matter hereof.

<PAGE>

          (d)  Succession and Assignment. This Agreement shall be binding upon
               -------------------------
and inure to the benefit of the Parties named herein and their respective
successors and permitted assigns. No Party may assign either this Agreement or
any of his or its rights, interests, or obligations hereunder without the prior
written approval of the Buyer and the Sellers; provided, however, that the Buyer
may (i) assign any or all of its rights and interests hereunder to one or more
of its Affiliates and (ii) designate one or more of its Affiliates to pay and
perform its obligations hereunder (in any or all of which cases the Buyer
nonetheless shall remain jointly and severally liable for the payment and

Any Party may send any notice, request, demand, claim, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,
telecopy, telex, ordinary mail, or electronic mail), but no such notice,

proven by the sender. Any Party may change the address to which notices,
requests, demands, claims, and other communications hereunder are to be
delivered by giving the other Parties notice in the manner herein set forth.

          (h)  Governing Law; Jurisdiction; Venue. This Agreement shall be
               ----------------------------------
governed and construed in accordance with the laws of the State of Colorado
excluding any conflicts or choice of law rule or principle that might otherwise
refer construction or interpretation of this Agreement to the substantive law of
another jurisdiction. Each of the Parties submits to the jurisdiction of any
state or federal court sitting in Denver, Colorado, in any action or proceeding
arising out of or relating to this Agreement and agrees that all claims in
respect of the action or proceeding may only be heard and determined in any such
court. These courts shall be the exclusive forum for the determination of any
claim or right arising out of or relating to this Agreement. Each of the Parties
waives any defense of inconvenient forum to the maintenance of any action or
proceeding so brought and waives any bond, surety, or other security that might
be required of any other Party with respect thereto. No Party will request the
court in any such action or proceeding to enter relief (whether for damages or
injunctive relief) until the opposing Party has had not less than seven (7) days
to respond to the request or motion for relief. Any Party may make service on
any other Party by sending or delivering a copy of the process to the Party to
be served at the address and in the manner provided for the giving of notices in
Section 11(g) of this Agreement. Each Party hereby waives any and all rights it
may have to a trial by jury. The parties acknowledge that by executing THIS
AGREEMENT, they are giving up all rights, if any, to a trial by jury.

          (i)  Attorneys Fees. The fees and costs, including reasonable
               --------------
attorneys' fees, incurred by any Party to this Agreement as a result of any
dispute arising under or related to this

                                       33
<PAGE>

Agreement shall be awarded to the prevailing party. If there is no prevailing
party, fees and costs may be awarded in the discretion of the court which, in
making such award, shall assess the relative good or bad faith of the Parties
throughout the dispute.

          (j)  Amendments and Waivers. No amendment of any provision of this
               ----------------------
Agreement shall be valid unless the same shall be in writing and signed by the
Buyer and the Sellers. No waiver by any Party of any default, misrepresentation,
or breach of warranty or covenant hereunder, whether intentional or not, shall
be deemed to extend to any prior or subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising
by virtue of any prior or subsequent such occurrence. (k) Severability. Any term
or provision of this Agreement that is invalid or unenforceable in any situation
in any jurisdiction shall not affect the validity or enforceability of the
remaining terms and provisions hereof or the validity or enforceability of the
offending term or provision in any other situation or in any other jurisdiction.

          (l)  Expenses. Each of the Parties and the Company will bear his or
               --------
its own costs and expenses (including legal fees and expenses) incurred in
connection with this Agreement and the transactions contemplated hereby.

          (m)  Construction. Any reference to any federal, state, local, or
               ------------
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty, and covenant contained herein shall have
independent significance. If any Party has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there
exists another representation, warranty, or covenant relating to the same
subject matter (regardless of the relative levels of specificity) which the
Party has not breached shall not detract from or mitigate the fact that the
Party is in breach of the first representation, warranty, or covenant.

          (n)  Incorporation of Exhibits and Schedules. The Exhibits and
               ---------------------------------------
Schedules identified in this Agreement are incorporated herein by reference and
made a part hereof.
