<PAGE>   4
endorsements printed, lithographed or engraved thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any stock exchange on which
the Warrants may be listed, or to conform to usage or to the requirements of
Section 2(b). The Warrant Certificates shall be dated the date of issuance
thereof (whether upon initial issuance, transfer, exchange or in lieu of
mutilated, lost, stolen, or destroyed Warrant Certificates) and issued in
registered form. Warrant Certificates shall be numbered serially with the
letters CW on the Class A Warrant Certificates of all denominations.

of the Company who shall have signed any of the Warrant Certificates shall cease
to be an officer of the Company or to hold the particular office referenced in
the Warrant Certificate before the date of issuance of the Warrant Certificates
or before countersignature by the Warrant Agent and issue and delivery thereof,
such Warrant Certificates may nevertheless be countersigned by the Warrant
Agent, issued and delivered with the same force and effect as though the person
who signed such Warrant Certificates had not ceased to be an officer of the
Company or to hold such office. After countersignature by the Warrant Agent,
Warrant Certificates shall be delivered by the Warrant Agent to the Registered
Holder without further action by the Company, except as otherwise provided by
Section 4 hereof.

     SECTION 4. EXERCISE. Each Class A Warrant may be exercised by the
Registered Holder thereof at any time on or after the Initial Exercise Date, but
not after the Warrant Expiration Date, upon the terms and subject to the
conditions set forth herein and in the applicable Warrant Certificate. A Warrant
shall be deemed to have been exercised immediately prior to the close of
business on the Exercise Date and the person entitled to receive the securities
deliverable upon such exercise shall be treated for all purposes as the holder
of those securities upon the exercise of the Warrant as of the close of business
on the Exercise Date. As soon as practicable on or after the Exercise Date the
Warrant Agent shall deposit the proceeds received form the exercise of a Warrant
and shall notify the Company in writing of the exercise of the Warrants.
Promptly following, and in any event within five days after the date of such
notice from the Warrant Agent, the Warrant Agent, on behalf of the Company,
shall cause to be issued and delivered by the Transfer Agent, to the person or
persons entitled to receive the same, a certificate or certificates for the
securities deliverable upon such exercise, (plus a certificate for any remaining
unexercised Warrants of the Registered Holder) unless prior to the date of
issuance of such certificates the Company shall instruct the Warrant Agent to
refrain from causing such issuance of certificates pending clearance of checks
received in payment of the Exercise Price pursuant to such Warrants. Upon the
exercise of any Warrants and clearance of the funds received, the Warrant Agent
shall promptly remit the payment received for the Warrant (the "Warrant
Proceeds") to the Company or as the Company may direct in writing, subject to
the provisions of Sections 9 hereof.

     SECTION 5.     RESERVATION OF SHARES; LISTING; PAYMENT OF TAXES; ETC.

     (a)  The Company covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issue
upon exercise of Class A Warrants, such number of shares of Common Stock as
shall then be issuable upon the exercise of all outstanding Class A Warrants.
The Company covenants that all shares of Common Stock which shall be issuable
upon exercise of the Class A Warrants shall, at the time of delivery, be duly
and validly issued, fully paid, nonassessable, and free from all preemptive or
similar rights, taxes, liens and charges with respect to the issue thereof,
(other than those which the Company shall promptly pay or discharge) and that
upon issuance such shares shall be listed on each national securities exchange
or eligible for inclusion in each automated quotation system, if any, on which
the other shares of outstanding Common Stock of the Company are then listed or
eligible for inclusion.

     (b)  The Company covenants that if any securities to be reserved for the
purpose of exercise of Warrants hereunder require registration with, or approval
of, any governmental authority under any federal securities law before such
securities may be validly issued or delivered upon such exercise, then the
Company will file a registration statement under the federal securities laws or
a post-effective amendment, use its best efforts to cause the same to become
effective and to keep such registration statement current while any of the
Warrants are outstanding and deliver a prospectus which complies with Section
10(a)(3) of the Act, to the Registered Holder exercising the Warrant (except, if
in the opinion of counsel to the Company, such registration is not required
under the federal securities law or if the Company receives a letter from the
staff of the Commission stating that it would not take any enforcement action if
such registration is not effected). The Company will use its best efforts to
obtain appropriate approvals or registrations under state "blue sky" securities
laws with respect to any such securities in the states where the registration
statement was initially registered. However, Warrants may not be exercised by,
or shares of Common Stock issued to, any Registered Holder in any state in which
such exercise would be unlawful.

     (c)  The Company shall pay all documentary, stamp or similar taxes and
other governmental charges that may be imposed with respect to the issuance of
Warrants, or the issuance or delivery of any shares upon exercise of the Class A
Warrants; provided, however, that if the shares of Common Stock or Class A
Warrants, as the case may be, are to be delivered in a name other than the name
of the Registered Holder of the Warrant Certificate representing any Warrant
being exercised, then no such delivery shall be made unless the person
requesting the same has paid to the Warrant Agent the amount of transfer taxes
or charges incident thereto, if any.

     (d)  The Warrant Agent is hereby irrevocably authorized as the Transfer
Agent to requisition from time to time certificates representing shares of
Common Stock or other securities required upon exercise of the Warrants, and the
Company will comply with all such requisitions.

    SECTION 6. EXCHANGE AND REGISTRATION TO TRANSFER.

    (a)  Warrant Certificates may be exchanged for other Warrant Certificates
representing an equal aggregate number of Warrants of the same class or may be
transferred in whole or in part. Warrant Certificates to be exchanged shall be
surrendered to the Warrant Agent at its Corporate Office, and upon satisfaction
of the terms and provisions hereof, the Company shall execute and the Warrant
Agent shall countersign, issue and deliver in exchange therefor the Warrant
Certificate or Certificates which the Registered Holder making the exchange
shall be entitled to receive.

    (b)  The Warrant Agent shall keep at its office books in which, subject to
such reasonable regulations as it may prescribe, it shall register Warrant
Certificates and the transfer thereof in accordance with its customary
practice. Upon due presentment for registration of transfer of any Warrant
Certificate at such office, the Company shall execute and the Warrant Agent
shall issue and deliver to the transferee or transferees a new Warrant
Certificate or Certificates representing an equal aggregate number of Class A
Warrants.

    (c)  With respect to all Warrant Certificates presented for registration or
transfer, or for exchange or exercise, the subscription or exercise form, as
the case may be, on the reverse thereof shall be duly endorsed, or be
accompanied by a written instrument or instruments of transfer and subscription,
in form satisfactory to the Company and the Warrant Agent, duly executed by the
Registered Holder or his attorney-in-fact duly authorized in writing.

    (d)  A service charge may be imposed by the Warrant Agent for any exchange
or registration or transfer of Warrant Certificates. In addition, the Company
may require payment by such holder of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection therewith.

    (e)  All Warrant Certificates surrendered for exercise or for exchange in
case of mutilated Warrant Certificates shall be promptly canceled by the
Warrant Agent and thereafter retained by the Warrant Agent until termination of
this Agreement or resignation as Warrant Agent, or disposed of or destroyed, at
the direction of the Company.

    (f)  Prior to due presentment for registration of transfer thereof, the
Company and the Warrant Agent may deem and treat the Registered Holder of any
Warrant Certificate as the absolute owner thereof and of each Warrant
represented thereby (notwithstanding any notations of ownership or writing
thereon made by anyone other than a duly authorized officer of the Company or
the Warrant Agent) for all purposes and shall not be affected by any notice to
the contrary.

    SECTION 7. LOSS OR MUTILATION. Upon receipt by the Company and the Warrant
Agent of evidence satisfactory to them of the ownership of and loss, theft,
destruction or mutilation of any Warrant Certificate and (in case of loss,
theft or destruction) of indemnity satisfactory to them, and (in the case of
mutilation) upon surrender and cancellation thereof, the Company shall execute
and the Warrant Agent shall (in the absence of notice to the Company and/or
Warrant Agent that the Warrant Certificate has been acquired by a bona fide
purchaser) countersign and deliver to the Registered Holder in lieu thereof a
new Warrant Certificate of like

                                       6

<PAGE>   7
tenor representing an equal aggregate number of Class A Warrants. Applicants for
a substitute Warrant Certificate shall comply with such other reasonable
regulations and pay such other reasonable charges as the Warrant Agent may
prescribe.

     SECTION 8. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES OF COMMON
     STOCK OR WARRANTS.

     (a)  Except as hereinafter provided, in the event the Company shall, issue
or sell any shares of Common Stock for a consideration per share less than the
Exercise price on the date of sale, or issue any shares of Common Stock as a
stock dividend to the holders of Common Stock, or subdivide or combine the
outstanding shares of Common Stock into a greater or lesser number of shares
(any such issuance, subdivision or combination being herein called a "Change of
Shares"), then, and thereafter upon each further Change of Shares, the Exercise
Price for the Warrants (whether or not the same shall be issued and outstanding)
in effect immediately prior to such Change of Shares shall be changed to a price
(including any applicable fraction of a cent to the nearest cent) determined by
dividing (i) the sum of (a) the total number of shares of Common Stock
outstanding immediately prior to such Change of Shares, multiplied by the
Exercise Price in effect immediately prior to such Change of Shares and (b) the
consideration, if any, received by the Company upon such sale, issuance,
subdivision or combination, by (ii) the total number of shares of Common Stock
outstanding immediately after such Change of Shares; PROVIDED, HOWEVER, that in
no event shall the Exercise Price be adjusted pursuant to this computation to an
amount in excess of the Exercise Price in effect immediately prior to such
computation, except in the case of a combination of outstanding shares of Common
Stock. For the purposes of any adjustment to be made in accordance with this
Section 8(a), the following provisions shall be applicable:

          (A)  In case of the issuance or sale of shares of Common Stock (or of
other securities deemed hereunder to involve the issuance or sale of shares of
Common Stock) for a consideration part or all of which shall be cash, the amount
of the cash portion of the consideration therefor deemed to have been received
by the Company shall be (i) the subscription price, if shares of Common Stock
are offered by the Company for subscription, or (ii) the public offering price
(before deducting therefrom any compensation paid or discount allowed in the
sale, underwriting or purchase thereof by underwriters or dealers or others
performing similar services, or any expenses incurred in connection therewith),
if such securities are sold to underwriters or dealers for public offering
without a subscription offering, or (iii) the gross amount of cash actually
received by the Company for such securities, in any other case.

          (B)  In case of the issuance or sale (otherwise than as a dividend or
other distribution on any stock of the Company, and otherwise than on the
exercise of options, rights or warrants or the conversion or exchange of
convertible or exchangeable securities) of shares of Common Stock (or of other
securities deemed hereunder to involve the issuance or sale of shares of Common
Stock) for a consideration part or all of which shall be other than cash, the
amount of the consideration therefor other than cash deemed to have been
received by the Company shall be the value of such consideration as determined
in good faith by the Board of Directors of the Company, using customary
valuation methods and on the basis of prevailing market values for similar
property or services.

                                       7
<PAGE>   8

          (C)  Shares of Common Stock issuable by way of dividend or other
distribution on any stock of the Company shall be deemed to have been issued
immediately after the opening of business on the day following the record date
for the determination of shareholders entitled to receive such dividend or other
distribution and shall be deemed to have been issued without consideration.

          (D)  The reclassification of securities of the Company other than
shares of Common Stock into securities including shares of Common Stock shall be
deemed to involve the issuance of such shares of Common Stock for a
consideration other than cash immediately prior to the close of business on the
date fixed for the determination of security holders entitled to receive such
shares, and the value of the consideration allocable to such shares of Common
Stock shall be determined as provided in subsection (B) of this Section 8(a).

          (E)  The number of shares of Common Stock at any one time outstanding
shall be deemed to include the aggregate maximum number of shares issuable
(subject to readjustment upon the actual issuance thereof) upon the exercise of
options, rights or warrants and upon the conversion or exchange of convertible
or exchangeable securities.

     (b)  Upon each adjustment of the Exercise Price pursuant to this Section
8, the number of shares of Common Stock purchasable upon the exercise of each
Warrant shall be the number derived by multiplying the number of shares of
Common Stock purchasable immediately prior to such adjustment by the Exercise
Price in effect prior to such adjustment and dividing the product so obtained
by the applicable adjusted Exercise Price.

     (c)  In case the Company shall at any time after the date hereof issue
options, rights or warrants to subscribe for shares of Common Stock, or issue
any securities convertible into or exchangeable for shares of Common Stock, for
a consideration per share (determined as provided in Sections 8(a) and 8(b) and
as provided below) less than the Exercise Price immediately before such
issuance, or without consideration (including the issuance of any such
securities by way of dividend or other distribution), the Exercise Price for
the Warrants (whether or not the same shall be issued and outstanding) in
effect immediately prior to the issuance of such options, rights or warrants,
or such convertible or exchangeable securities, as the case may be, shall be
reduced to a price determined by making the computation in accordance with the
provisions of Sections 8(a) and 8(b) hereof, PROVIDED that:

          (A)  The aggregate maximum number of shares of Common Stock, as the
case may be, issuable or that may become issuable under such options, rights or
warrants (assuming exercise in full even if not then currently exercisable or
currently exercisable in full) shall be deemed to be issued and outstanding at
the time such options, rights or warrants were issued, for a consideration
equal to the minimum purchase price per share provided for in such options,
rights or warrants at the time of issuance, plus the consideration, if any,
received by the Company for such options, rights or warrants; PROVIDED,
HOWEVER, that upon the expiration or other termination of such options, rights
or warrants, if any thereof shall not have been exercised, the number of shares
of Common Stock deemed to be issued and outstanding pursuant to this subsection
(A) (and for the purposes of subsection (E) of Section 8(a) hereof) shall be
reduced by the number of shares as to which options, warrants and/or rights
shall have expired, and such number of shares shall no longer be deemed to be
issued and outstanding, and the Exercise Price then in effect shall forthwith
be readjusted and thereafter be the price

                                       8
<PAGE>   9
that it would have been had adjustment been made on the basis of the issuance
only of the shares actually issued plus the shares remaining issuable upon the
exercise of those options, rights or warrants as to which exercise rights shall
not have expired or terminated unexercised.

          (B)  The aggregate maximum number of shares of Common Stock issuable
or that may become issuable upon conversion or exchange of any convertible or
exchangeable securities (assuming conversion or exchange in full even if not
then currently convertible or exchangeable in full) shall be deemed to be issued
and outstanding at the time of issuance of such securities, for a consideration
equal to the consideration received by the Company for such securities, plus the
minimum consideration, if any, receivable by the Company upon the conversion or
exchange thereof; PROVIDED, HOWEVER, that upon the termination of the right to
convert or exchange such convertible or exchangeable securities (whether by
reason of redemption or otherwise), the number of shares of Common Stock deemed
to be issued and outstanding pursuant to this subsection (B) (and for the
purposes of subsection (E) of Section 8(a) hereof) shall be reduced by the
number of shares as to which the conversion or exchange rights shall have
expired or terminated unexercised, and such number of shares shall no longer be
deemed to be issued and outstanding, and the Exercise Price then in effect shall
forthwith be readjusted and thereafter be the price that it would have been had
adjustment been made on the basis of the issuance only of the shares actually
issued plus the shares remaining issuable upon conversion or exchange of those
convertible or exchangeable securities as to which the conversion or exchange
rights shall not have expired or terminated unexercised.

          (C)  If any change shall occur in the price per share provided for in
any of the options, rights or warrants referred to in subsection (A) of this
Section 8(c), or in the price per share or ratio at which the securities
referred to in subsection (B) of this Section 8(c) are convertible or
exchangeable, such options, rights or warrants or conversion or exchange rights,
as the case may be, to the extent not theretofore exercised, shall be deemed to
have expired or terminated on the date when such price change became effective
in respect of shares not theretofore issued pursuant to the exercise or
conversion or exchange thereof, and the Company shall be deemed to have issued
upon such date new options, rights or warrants or convertible or exchangeable
securities.

     (d)  In case of any reclassification or change of outstanding shares of
Common Stock issuable upon exercise of the Warrants (other than a change in par
value, or from par value to no par value, or from no par value to par value or
as a result of a subdivision or combination), or in case of any consolidation
or merger of the Company with or into another corporation (other than (1) a
merger with a subsidiary of the Company in which merger the Company is the
continuing corporation or (2) any consolidation or merger of the Company with
or into another corporation which, in either instance, does not result in any
reclassification or change of the then outstanding shares of Common Stock or
other capital stock issuable upon exercise of the Warrants (other than a change
in par value, or from par value to no par value, or from no par value to par
value or as a result of subdivision or combination)) or in case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, then, as a condition of such reclassification,
change, consolidation, merger, sale or conveyance, the Company, or such
successor or purchasing corporation, as the case may be, shall make lawful and
adequate provision whereby the Registered Holder of each Warrant then
outstanding shall have the right thereafter to receive on exercise of such
Warrant the kind and amount of securities and property receivable upon such
reclassification, change,

                                       9
<PAGE>   10
consolidation, merger, sale or conveyance by a holder of the number of
securities issuable upon exercise of such Warrant immediately prior to such
reclassification, change, consolidation, merger, sale or conveyance and shall
forthwith file at the Corporate Office of the Warrant Agent a statement signed
by its Chief Executive Officer, President or a Vice President and by its
Treasurer or an Assistant Treasurer or its Secretary or an Assistant Secretary
evidencing such provision. Such provisions shall include provision for
adjustments, which shall be as nearly equivalent as may be practicable to the
adjustments provided for in Sections 8(a), (b) and (c). The above provisions of
this Section 8(d) shall similarly apply to successive reclassifications and
changes of shares of Common Stock and to successive consolidations, mergers,
sales or conveyances.

     (e)  Irrespective of any adjustments or changes in the Exercise Price or
the number of shares of Common Stock purchasable upon exercise of the Warrants,
the Warrant Certificates theretofore and thereafter issued shall, unless the
Company shall exercise its option to issue new Warrant Certificates pursuant to
Section 2(e) hereof, continue to express the Exercise Price per share and the
number of shares purchasable thereunder as the Exercise Price per share and the
number of shares purchasable thereunder were expressed in the Warrant
Certificates when the same were originally issued.

     (f)  After each adjustment of the Exercise Price pursuant to this Section
8, the Company will promptly prepare a certificate signed by the Chairman, Chief
Executive Officer or President, and by the Treasurer or an Assistant Treasurer
or the Secretary or an Assistant Secretary, of the Company setting forth: (i)
the Exercise Price as so adjusted, (ii) the number of shares of Common Stock
purchasable upon exercise of each Warrant, after such adjustment, and (iii) a
brief statement of the facts accounting for such adjustment. The Company will
promptly file such certificate with the Warrant Agent and cause a brief summary
thereof to be sent by ordinary first class mail to each Registered Holder at his
last address as it shall appear on the registry books of the Warrant Agent. No
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity thereof except as to the holder to whom the Company
failed to mail such notice, or except as to the holder whose notice was
defective. The affidavit of an officer of the Warrant Agent or the Secretary or
an Assistant Secretary of the Company that such notice has been mailed shall, in
the absence of fraud, be prima facie evidence of the facts stated therein.

     (g)  No adjustment of the Exercise Price shall be made as a result of or in
connection with (A) the issuance or sale of shares of Common Stock pursuant to
options, warrants, stock purchase agreements and convertible or exchangeable
securities outstanding or in effect on the date hereof and on the terms
described in the final prospectus relating to the public offering contemplated
by the Underwriting Agreement; (B) stock options to be granted under the
Company's 1997 Stock Option Plan; (C) the issuance or sale of shares of Common
Stock upon the conversion of the shares of Series A Convertible Preferred Stock
which comprise a part of the Units; or (D) the issuance or sale of shares of
Common Stock if the amount of said adjustment shall be less than $.10, PROVIDED,
HOWEVER, that in such case, any adjustment that would otherwise be required then
to be made shall be carried forward and shall be made at the time of and
together with the next subsequent adjustment that shall amount, together with
any adjustment so carried forward, to at least $.10. In addition, Registered
Holders shall not be entitled to cash dividends paid by the Company prior to the
exercise of any Warrant or Warrants held by them.

     SECTION 9. FRACTIONAL WARRANTS AND FRACTIONAL SHARES.

     (a)  If the number of shares of Common Stock purchasable upon the exercise
of each Class A Warrant is adjusted pursuant to Section 8 hereof, the Company
nevertheless shall not be required to issue fractions of shares, upon exercise
of the Class A Warrants or otherwise, or to distribute certificates that
evidence fractional shares. With respect to any fraction of a share called for
upon any exercise hereof, the Company shall pay to the Holder an amount in cash
equal to such fraction multiplied by the current market value of such share,
determined as follows:

          (1)  If the Common Stock is listed on a National Securities Exchange
or admitted to unlisted trading privileges on such exchange or listed for
trading on the National Market System of NASDAQ or traded on NASDAQ, the
current value shall be the last reported sale price of the Common Stock on such
exchange on the last business day prior to the date of exercise of this Warrant
or if no such sale is made on such day, the average of the closing bid and
asked prices for such day on such exchange or system; or

          (2)  If the Common Stock is not listed or admitted to unlisted
trading privileges, the current value shall be the mean of the last reported
bid and asked prices reported by the National Quotation Bureau, Inc. on the
last business day prior to the date of the exercise of this Warrant; or

          (3)  If the Common Stock is not so listed or admitted to unlisted
trading privileges and bid and asked prices are not so reported, the current
value shall be an amount determined in such reasonable manner as may be
prescribed by the Board of Directors of the Company.

     SECTION 10. WARRANT HOLDERS NOT DEEMED STOCKHOLDERS. Except as otherwise
provided, no holder of Warrants shall, as such, be entitled to vote or to
receive dividends or be deemed the holder of Common Stock that may at any time
be issuable upon exercise of such Warrants for any purpose whatsoever, nor
shall anything contained herein be construed to confer upon the holder of
Warrants, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issue or reclassification
of stock, change of par value or change of stock to no par value,
consolidation, merger or conveyance or otherwise), or to receive notice of
meetings, or to receive dividends or subscription rights, until such Holder
shall have exercised such Warrants and been issued shares of Common Stock in
accordance with the provisions hereof.

     SECTION 11. RIGHTS OF ACTION. All rights of action with respect to this
Agreement are vested in the respective Registered Holders of the Warrants, and
any Registered Holder of a Warrant, without consent of the Warrant Agent or of
the holder of any other Warrant, may, in his own behalf and for his own
benefit, enforce against the Company his right to exercise his Warrants for the
purchase of shares of Common Stock in the manner provided in the Warrant
Certificate and this Agreement.

<PAGE>   12
     SECTION 12. AGREEMENT OF WARRANT HOLDERS. Every holder of a Class A
Warrant, by his acceptance thereof, consents and agrees with the Company, the
Warrant Agent and every other holder of a Warrant that:

     (a)  The Class A Warrants are transferable only on the registry books of
the Warrant Agent by the Registered Holder thereof in person or by his attorney
duly authorized in writing and only if the Warrant Certificates representing
such Warrants are surrendered at the office of the Warrant Agent, duly endorsed
or accompanied by a proper instrument of transfer satisfactory to the Warrant
Agent and the Company in their sole discretion, together with payment of any
applicable transfer taxes; and

     (b)  The Company and the Warrant Agent may deem and treat the person in
whose name the Warrant Certificate is registered as the holder and as the
absolute, true and lawful owner of the Warrants represented thereby for all
purposes, and neither the Company nor the Warrant Agent shall be affected by
any notice or knowledge to the contrary, except as otherwise expressly provided
in Section 7 hereof.

     SECTION 13. CANCELLATION OF WARRANT CERTIFICATES. If the Company shall
purchase or acquire any Warrant or Warrants, the Warrant Certificate or Warrant
Certificates evidencing the same shall thereupon be delivered to the Warrant
Agent and canceled by it and retired. The Warrant Agent shall also cancel
Common Stock following exercise of any or all of the Warrants represented
thereby or delivered to it for transfer, split up, combination or exchange.

     SECTION 14. CONCERNING THE WARRANT AGENT.

     (a)  The Warrant Agent acts hereunder as agent and in a ministerial
capacity for the Company, and its duties shall be determined solely by the
provisions hereof. The Warrant Agent shall not, by issuing and delivering
Warrant Certificates or by any other act hereunder be deemed to make any
representations as to the validity, value or authorization of the Warrant
Certificates or the Warrants represented thereby or of any securities or other
property delivered upon exercise of any Warrant or whether any stock issued
upon exercise of any Warrant is fully paid and nonassessable.

     (b)  The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of Warrant Certificates to make or cause to be
made any adjustment of the Exercise provided in this Agreement, or to determine
whether any fact exists which may require any such adjustments, or with respect
to the nature or extent of any such adjustment, when made, or with respect to
the method employed in making the same. It shall not (i) be liable for any
recital or statement of facts contained herein or for any action taken,
suffered or omitted by it in reliance on any Warrant Certificate or other
document or instrument believed by it in good faith to be genuine and to have
been signed or presented by the proper party or parties, (ii) be responsible
for any failure on the part of the Company to comply with any of its covenants
and obligations contained in this Agreement or in any Warrant Certificate, or
(iii) be liable for any act or omission in connection with this Agreement
except for its own negligence or willful misconduct.

     (c)  The Warrant Agent may at any time consult with counsel satisfactory
to it (who may be counsel for the Company) and shall incur no liability or
responsibility for any action

                                       12
<PAGE>   13
taken, suffered or omitted by it in good faith in accordance with the opinion or
advice of such counsel.

     (d)  Any notice, statement, instruction, request, direction, order or
demand of the Company shall be sufficiently evidenced by an instrument signed
by the Chairman of the Board, President, any Vice President, its Secretary, or
Assistant Secretary, (unless other evidence in respect thereof is herein
specifically prescribed). The Warrant Agent shall not be liable for any action
taken, suffered or omitted by it in accordance with such notice, statement,
instruction, request, direction, order or demand believed by it to be genuine.

     (e)  The Company agrees to pay the Warrant Agent reasonable compensation
for its services hereunder and to reimburse it for its reasonable expenses
hereunder; it further agrees to indemnify the Warrant Agent and save it
harmless against any and all losses, expenses and liabilities, including
judgments, costs and counsel fees, for anything done or omitted by the Warrant
Agent in the execution of its duties and powers hereunder except losses,
expenses and liabilities arising as a result of the Warrant Agent's negligence
or willful misconduct.

     (f)  The Warrant Agent may resign its duties and be discharged from all
further duties and liabilities hereunder (except liabilities arising as a
result of the Warrant Agent's own negligence or willful misconduct), after
giving 30 days' prior written notice to the Company. At least 15 days prior to
the date such resignation is to become effective, the Warrant Agent shall cause
a copy of such notice of resignation to be mailed to the Registered Holder of
each Warrant Certificate at the Company's expense. Upon such resignation, or
any inability of the Warrant Agent to act as such hereunder, the Company shall
appoint a new warrant agent in writing. If the Company shall fail to make such
appointment within a period of 15 days after it has been notified in writing of
such resignation by the resigning Warrant Agent, then the Registered Holder of
any Warrant Certificate may apply to any court of competent jurisdiction for
the appointment of a new warrant agent. Any new warrant agent, whether
appointed by the Company or by such a court, shall be a bank or trust company
having a capital and surplus, as shown by its last published report to its
stockholders, of not less than $10,000,000 or a stock transfer company. After
acceptance in writing of such appointment by the new warrant agent is received
by the Company, such new warrant agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named herein as
the Warrant Agent, without any further assurance, conveyance, act or deed; but
if for any reason it shall be necessary or expedient to execute and deliver any
further assurance, conveyance, act or deed, the same shall be done at the
expense of the Company and shall be legally and validly executed and delivered
by the resigning Warrant Agent. Not later than the effective date of any such
appointment the Company shall file notice thereof with the resigning Warrant
Agent and shall forthwith cause a copy of such notice to be mailed to the
Registered Holder of each Warrant Certificate.

     (g)  Any corporation into which the Warrant Agent or any new warrant agent
may be converted or merged or any corporation resulting from any consolidation
to which the Warrant Agent or any new warrant agent shall be a party or any
corporation succeeding to the trust business of the Warrant Agent shall be a
successor warrant agent under this Agreement without any further act, provided
that such corporation is eligible for appointment as successor to the Warrant
Agent under the provisions of the preceding paragraph. Any such successor
warrant

                                       13
<PAGE>   14
agent shall promptly cause notice of its succession as warrant agent to be
mailed to the Company and to the Registered Holder of each Warrant Certificate.

     (h)  The Warrant Agent, its subsidiaries and affiliates, and any of its or
their officers or directors, may buy and hold or sell Warrants or other
securities of the Company and otherwise deal with the Company in the same
manner and to the same extent and with like effects as though it were not
Warrant Agent. Nothing herein shall preclude the Warrant Agent from acting in
any other capacity for the Company or for any other legal entity.

     (i)  The Warrant Agent shall retain for a period of two years from the
date of exercise any Warrant Certificate received by it upon such exercise.

     SECTION 15. MODIFICATION OF AGREEMENT. Subject to the provisions of
Section 5(b), the Warrant Agent and the Company may by supplemental agreement

appropriate to cure any ambiguity or to correct any defective or inconsistent
provision or manifest mistake or error herein contained; or (ii) that they may
deem necessary or desirable and which shall not adversely affect the interests
of the holders of Warrant Certificates; provided, however, that no change in
the number or nature of the securities purchasable upon the exercise of any
Warrant, or to increase the Exercise Price therefor or to accelerate the
Warrant Expiration Date, shall be made without the consent in writing of the
Registered Holders representing not less than 66-2/3% of the Warrants then
outstanding, other than such changes as are presently specifically prescribed
by this Agreement as originally executed. In addition, this Agreement may not
be modified, amended or supplemented without the prior written consent of the
Representative, other than to cure any ambiguity or to correct any provision

such change that is necessary or desirable and which shall not adversely affect
the interest of the Representative and except as may be required by law.

                        FIRST AMENDMENT TO 1998 AGREEMENT

         WHEREAS, the Farmers Reservoir and Irrigation Company ("FRICO") and
Eldorado Artesian Springs, Inc. ("Eldorado") (collectively the "Parties") on
December 8, 1998 entered into an agreement with respect to, inter alia, the
acquisition and use of one unit of the Windy Gap Project water from the Northern
Colorado Water Conservancy District, now owned by the Superior Metropolitan
District ("1998 Agreement"); and

         WHEREAS, paragraph 2 of the 1998 Agreement provides as follows:

                  Any such agreement between FRICO and the Superior Metropolitan
                  District ("FRICO/Superior Agreement") must be concluded within
                  ninety (90) days of this Agreement, unless such time period is
                  extended by mutual agreement of the parties. The terms of the
                  FRICO/Superior Agreement must be fully acceptable to Eldorado;
                  or the$10,000.00 initial payment will be refunded to Eldorado
                  and this Agreement will terminate.

         WHEREAS, the Parties, as of this date, are awaiting confirmation of the
transfer of one unit of Windy Gap Project water from the Superior District; and

         WHEREAS, the Parties desire to provide for an alternative water supply
for Eldorado in the event that the Windy Gap Project water is not available from
Superior; and

         WHEREAS, by virtue of the agreement between FRICO and Superior, other
water is being made available to FRICO which can be incorporated into a program
for augmentation for Eldorado.

         NOW, THEREFORE, it is agreed as follows:

         1. FRICO is the recipient of the water allocated to Superior on
approximately 100 shares of FRISCO stock owned by the Superior Metropolitan
District.

         2. FRICO will issue one additional share of stock presently held in the
FRICO treasury which stock will be entitled to the special presumptive
allocation of 100 acre-feet of consumptive use water. The presumptive allocation
of 100 acre-feet shall be divided into ten options, each for 10 acre-feet of
consumptive use water, and the water represented by each option will be
delivered to or for the benefit of Eldorado through a plan of augmentation.

         3. Within thirty (30) days after execution of this Agreement, FRICO and
Eldorado will proceed with an application for change of water right and for a
plan of augmentation using water identified in paragraph 1, above, in the same
manner as set forth in the FRICO/Eldorado agreement to which this Amendment is
attached. Also upon closing, Eldorado shall pay FRICO a non-refundable
$10,000.00 for the options. Upon entry of a decree acceptable to FRICO and

<PAGE>   2

Eldorado, Eldorado may exercise as many of the options as it desires. The
exercise price for each option shall be $91,600.00 for each 10 acre-feet of
consumptive use. The option price for each 10 acre-foot option not exercised in
any given year will be increase by nine percent (9%) each year, beginning with
the date of the entry of the acceptable decree. Eldorado can exercise the
options at any time, provided, however, that the exercise of the option rights
for unexercised options shall all expire on the tenth anniversary of the entry
of the decree. In the event that the Water Court determines that more or less
consumptive use is available than 100 acre-feet per year, there may be more or
less than 10 acre-foot options. In addition, there may also be partial 10
acre-foot options in the event that the amount of consumptive use determined to
be available by the Water Court is not evenly divisible by 10. For example, if
the Water Court determines that 93 acre-feet per year of consumptive use are
available, there would be nine 10 acre-foot options and one 3 acre-foot option.
The price of any partial 10 acre-foot option shall be based on the price of
$9,160.00 per acre-foot as of the date of entry of the decree, subject to
increase of nine percent (9%) each year as provided above.

         4. Eldorado shall have the right to proceed with the acquisition of the
Windy Gap Project water as set forth in the attached agreement as it may, from
time to time, be amended. Alternatively, at Eldorado's election, the application
may proceed with the Marshall Lake water which is the subject of this Amendment
under the terms of this Amendment, or may proceed with both the Windy Gap
Project water and the Marshall Lake water which is the subject of this
Amendment, in which case the payment schedules of both this Amendment and the
provisions of the FRICO/Eldorado Agreement shall be applicable.

         5. In the event that a mutually acceptable decree is not obtained,
Eldorado shall have the right to terminate this agreement, each party being
released from all terms and provisions of this agreement, and each party shall
bear its own cost and expenses incurred, provided that FRICO shall be entitled
to retain the $10,000.00 paid by Eldorado in consideration of the options.

         6. In addition to the payments as set forth above, Eldorado shall pay
to FRICO the amount equal to the annual stock assessment on four (4) shares of
the stock allocated for water delivery purposes to the Marshall Lake Division
for each 10 acre-foot option exercised by Eldorado. Said assessment shall be
paid in the same manner as stock assessments in the company generally.

         Dated this 11th day of July, 2000.
